The sieve section comprises a plurality of ring elements arranged on top of each other. The ring elements are provided with distance elements determining thedistance between adjacent ring elements, the distance elements being formed as projections and recesses of stepwise heights and depths, respectively, or as mutually collaborating wedge units so as to allow an arbitrary setting of the ring distance.
4 Claims, 6 Drawing Figures FOUNTAIN WELL The present invention relates to a fountain (bored) well that is designed to be placed in a hole drilled into the earth for pumping a liquid and that comprises a silt pipe at the lower end of the bored well, an extension pipe constituting the top section of the well, and a sieve section arranged between these, which sieve section is fitted with a pump, from which, on the other hand, a piping is arranged to the drainage point of the liquid, whereby the sieve section comprises several rings or equivalent positioned on top of each other, the mutual distances of which rings are determined by means of distance elementslocated on the rings and corresponding to each other.
The well, which is located in a hole drilled into the earth (see FIG. 1), comprises a silt pipel, a sieve section 2, and an extension pipe 3. Inside the sieve section, a pump 4 is located, from which a piping leads to the drainage point of the water.
The water in the earth layers has access to the pumping space through the sieve section 2. On the basis of the structure of the surrounding soil and of the ground water supply, the slit size of the sieve pipe and the length of the sieve section are determined. This is why, from a good sieve pipe, light and easy adjustability of the water slit and possibility ofjoining the components are required;
The sieve pipes at present in use are made, among other things, of wood, ceramic materials, metal or plastics, and as extension pipes havebeen used steel or plastics pipes with threaded or flanged joints. In all of the above constructions it has not been easy to change the slit size of the sieve section but it has usually been constructed as fixed.
Since in the above constructions the slit adjustment has not been possible at the installation site, it has not been possible to choose theappropriate sieve pipe until the drilling has proceeded deep enough and the soil thus been studied. This is why sieve pipes with different slit sizes must be kept on stock. The constructions used are very expensive, because their manufacturing is difficult. Often the shape of the slitcannot be economically manufactured so that it would notbe blockedby soil particles carried by water. Flange, threaded etc. joints of the sieve and extension pipes increase the pipe diameter and in this way alter the flow characteristics especially of the sieve pipe. The joints used are also expensive and slow to install. 1
A purpose of the present invention is to avoid ;the above disadvantages and to produce an ever more eff cient fountain well. A bored .well, according to the invention is mainly characterized in that the distance elements are formed as projections and recesses of stepwise heights and depths, respectively, or as mutually colaboratin g wedge units so as toallow any desired setting of the ring distance.
In the following, the invention will be examined more closely with the aid of the embodiments according to the attached drawings. v
FIG. 1 shows, as'has already come out, a schematic view of a well according to the invention.
FIG. 2 shows, on an enlarged scale and as a partial cross section, the sieve section of the well of FIG. 1.
FIG. 3 shows, a partial section of one arrangement of rings of the sieve section of the well according to the invention.
Thus, the well pipe system according to the present invention consists of an extension pipe, a silt pipe 1, a
joint band 9, a body or framework 10 of the sieve section 4, and of adjustment rings 1 1, 12 around the body, made of various plastics by means of various manufacturing techniques (FIG. 2).
The water slit 19 is in the sieve pipe 4 according to the invention adjustable with sufficiently small steps or continuously within a certain range. The sieve units and the extension pipes 3 can be joined simply and rapidly to any required length. Under these circumstances, the size of the slit 1'9 may be determined at the installation site, and one basic unit is adequate for storage. In this construction it is possible to make the water slit 19 more favourable for the water flow. By means of shaping it is also possible to reduce the blocking of the water slit by gravel. By manufacturing the entire system out of plastics, corrosion, decaying etc. troubles are avoided. Moreover, the friction coefficient of plastics is low, and so the silt carried from the soil by water does not block the sieve pipe construction.
The extensionpipe 3 is shaped so that its components are partly inserted into each other and that a groove 7 is formed at the joint. The extension pipe accommodates a slot 8 at the groove -7, through which slot the locking band 9 is inserted into the groove 7.
The sieve section 4 consists of a body or body framework 10, around which adjustment rings 11 and 12 are piled. The top section of the body 10 has a relieved thread section 13, and the adjustment rings 11 and 12 are tightened by means of a nut 14 adapted to the thread'section. The top and bottom section of the body 10 has jointing units similar to those in the extension pipe 3. The bottom end of the sieve section accommodates a silt pipe I, as which in the system according to the present invention, for example, an extension pipe 3 is suitable. The bottom end of the silt pipe is closed by a plug 15.
FIG. 3 shows one arrangement of adjustment rings 11 and 12. Ring 11 has on the surfach 16 recesses 17 of different depths, into which the projections 18 on the ring 12 are fitted. By in this way alternatingly placing rings 11 and l2-onto the body 10 (FIG. 2) so that the projections 18 meet the desired recesses 17, the mutual distance of the rings (water slit) 19 can be adjusted almost continuously.
FIG. 4 shows another arrangement of setting the water slit l9. Herein the ring 11 is fitted with a wedgeshaped recess 20 that the grooves or is otherwise roughened and the ring 12 is fitted with a wedgeshaped projection 21 that matches the recess 20. By turning the rings it is possible to adjust the height of the water slit 19.-
A well pipe system according to the invention is assembled so that an extension pipe 3 (FIG. 2) is closed with a plug 15, after which it is suitable as a silt pipe 1. To this silt pipe 1 a desired number of sieve section bodies 10 are joined by means of locking band 9. The extensionor silt pipe has a flange 22, on top of which sieve rings 11 and 12 are placed in positions required by the necessary water slit. Finally, the pile of rings in this way assembled is tightened bymeans of a nut 14 at the top end of the body 10. By means of the method of joining previously described a necessary number of extension pipes 3 are joined to the top end of the body 6.
FIGS. 5 and 6 show an additional embodiment of the invention. FIG. 5 shows the sieve pipe as viewed from above and FIG. 6 the sieve rings.
The adjustment rings 24 have, with uniform distances, on both sides of the ring, circumferential wedge faces 26 and projecting faces 25. The rings 24, which are in themselves identical, are arranged on top of each other so that the wedge face sections 26 of the rings are on every second ring narrowed in one direction and on every second ring in the opposite direction. By locating the projecting face 25 of one ring 24 against differnt points of the next rings wedge face 26, the ring distance 19 can be adjusted as desired. The inner face of each ring 24 has a pin 27 that can be accommodated to guide grooves 28 on the outer face of the body framework 10, which grooves are located asymmetrically in relation to each other. These guide grooves 28 are preferably accommodated with an evenly increasing phase transfer A in relataion to each other.
Thus, if pin 27 of one ring is placed in the guide groove 28 at point 0,0 (FIG. 7) and the pin of the next ring, 27, (with the ring upside down) in the corresponding guide groove at point 1,0, a relatively small ring distance (water slit) is obtained. By placing the pin 27 of the second ring in the guide groove at point 2,0, correspondingly a double slit is obtained, etc,
