[0022] DETAILED DESCRIPTION

[0023] ​​To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] like Figures 1-6 As shown, a self-cleaning filtration device for water conservancy projects includes a filter box 1. A filter shell 6 is fixedly connected to the inner side of the filter box 1 on one side of a known connecting pipe. One side of the filter shell 6 has an inlet 13, and the other side is connected to the known connecting pipe port. A baffle 14 is fixedly connected to the middle of the inner wall of the filter shell 6, dividing the internal space of the filter shell 6 into a left chamber 9 and a right chamber 10. The baffle 14 ensures that the wastewater initially filtered by the filter box 1 only enters the right chamber 10 through the inlet 13, then flows along the right chamber 10 into the known connecting pipe, and finally into the treatment box. The inlet 13 is located inside the right chamber 10. A gear shaft 15 is rotatably connected to the center line of the right chamber 10. Several filter plates 11 arranged in a circular array are fixedly connected to the gear shaft 15 along its center line. The filter plates 11 are slidably connected to the baffle 14 and the inner wall of the right chamber 10. The opening between two adjacent filter plates 11 is equivalent to the inlet 13. Before reaching the connecting pipe, the sewage passing through the inlet 13 is filtered by several filter plates 11, which can prevent unfiltered mud and sand in the sewage from entering the connecting pipe and instead accumulate between the two filter plates 11 connected to the inlet 13. One end of the gear shaft 15 extends through the baffle 14 into the left chamber 9, and the baffle 14 is rotatably connected to a spur gear 17 that meshes with the gear shaft 15 on one side of the left chamber 9. When the amount of mud and sand filtered between the two filter plates 11 near the inlet 13 increases and affects the water flow in the right chamber 10, the rotation of the spur gear 17 can achieve the rotation of the gear shaft 15, which can rotate the two adjacent filter plates 11 that have accumulated mud and sand to be offset from the inlet 13. That is, other empty adjacent filter plates 11 can be moved to both sides of the inlet 13 to continue filtering the mud and sand.

[0026] To further clean the silt accumulated between the two adjacent filter plates 11, the two adjacent filter plates 11 with accumulated silt are rotated to the position of the telescopic shell 12. A screw 16, parallel to the center line of the right chamber 10, is threaded into the left chamber 9. A telescopic shell 12, sliding along the length of the gear shaft 15 and penetrating the baffle 14, is threaded onto the surface of the screw 16. Rotation of the screw 16 allows the telescopic shell 12 to be inserted between the two adjacent filter plates 11 at the corresponding positions. The outer wall of the telescopic shell 12 is slidably connected to the inner wall of the space formed between the two adjacent filter plates 11. The side of the telescopic shell 12 facing the right chamber 10 is recessed and equipped with a switch valve 18. When the telescopic shell 12 is inserted… Before the two filter plates 11 are positioned, the switch valve 18 is remotely controlled to open automatically. This allows the silt and sand between the adjacent filter plates 11 to be collected into the telescopic housing 12 during its forward movement via the open switch valve 18. When the telescopic housing 12 fully enters the right chamber 10 and retracts to its original position, the switch valve 18 closes. A sealing plate 19 is embedded in the side of the telescopic housing 12 located above the inlet 13 and away from the right chamber 10 via a spring rod. A discharge pipe 7, aligned with the center line of the sealing plate 19, is fixedly connected through the wall of the filter box 1. Push rods 20, used to open the sealing plate 19, are fixedly connected to the inner walls of some openings of the discharge pipe 7 facing the right chamber 10. Figure 6 As shown, when the telescopic shell 12 is located in the left chamber 9, the push rod 20 pushes the sealing plate 19 to move against the thrust of the spring rod, thus opening the right end face of the telescopic shell 12 and connecting it with the discharge pipe 7. Therefore, when the telescopic shell 12 collecting mud and sand retracts and returns to its original position... Figure 6 In the indicated state, the collected silt mixed with a small amount of sewage can be discharged through the open sealing plate 19. Moreover, when the telescopic shell 12 moves forward, the sealing plate 19 disengages from the push rod 20, and can be resealed at the right end of the telescopic shell 12 under the pushing action of the spring rod, preventing the silt from re-entering the filter box 1 through the open sealing plate 19 at the right port of the telescopic shell 12 during silt collection. Motors 8 are fixedly connected to the outer wall of the filter box 1 and the left chamber 9, and the two motors 8 are used to drive the screw 16 and the spur gear 17 to rotate, respectively.

[0027] Further: the filter box 1 is further provided with a known filter grid 2 near the top of the box, the bottom corners of the filter grid 2 are fixedly connected with springs 5, the bottom ends of the springs 5 are connected with the bottom of the filter box 1 through waterproof electric telescopic rods 4, the upper opening of the filter box 1 is fixedly connected with two parallel distributed and upper and lower staggered arranged blocking rods 3, the side surface bottom edge position of the blocking rod 3 near the lower position of the filter grid 2 is throughly arranged, in actual use, the waterproof electric telescopic rod 4 is elongated to realize the rising of the filter grid 2 until the lower position of the blocking rod 3 on the left side of the filter grid 2 is contacted, and under the hindering action, when the waterproof electric telescopic rod 4 continuously elongates, the two springs 5 on the left side are elastically contracted, and at the same time, the filter grid 2 is inclined to the right side, so that the first filtered sundries in the filter grid 2 can be discharged and fallen off along the through hole at the bottom of the left side.

[0028] Working principle, the sewage is poured into the filter box 1, and is collected in the filter box 1 under the preliminary filtration of the filter grid 2, before the sewage enters the connecting pipe, through the water inlet 13 into the right chamber 10, after layer upon layer filtration through a plurality of filter plates 11, the sewage is further filtered, the impurities are accumulated between the adjacent two filter plates 11 near the water inlet 13, after waiting for a period of time, the adjacent two filter plates 11 of the accumulated silt can be rotated to be staggered with the water inlet 13 and moved to the telescopic shell 12 by rotating the spur gear 17 to realize the meshing connection of the gear shaft 15, the opening valve 18 is opened, the telescopic shell 12 is inserted between the adjacent two filter plates 11 in the corresponding position by rotating the screw rod 16, in the advancing process of the telescopic shell 12, the silt between the adjacent two filter plates 11 is collected into the telescopic shell 12 through the opened opening valve 18, after the telescopic shell 12 completely enters the right chamber 10, the opening valve 18 is closed before the telescopic shell 12 retreats and resets, then with the telescopic shell 12 resetting into the left chamber 9, the silt accumulated between the adjacent two filter plates 11 can be removed.

[0029] The wiring diagram of the waterproof electric telescopic rod 4, the opening valve 18 and the motor 8 in the utility model belongs to the common knowledge in the field, the working principle is a known technology, and the type is selected according to the actual use, so the control mode and the wiring arrangement of the waterproof electric telescopic rod 4, the opening valve 18 and the motor 8 are not explained in detail.
