Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-6 The utility model provides a technical solution: a dewatering device for narrow rock and soil foundation pits, comprising a plurality of curved connecting pipes 3, both ends of the curved connecting pipes 3 are provided with quick-connection mechanisms 5, and a well point pipe 6 is provided at the bottom of one of the quick-connection mechanisms 5, and a main pipe 7 is provided at the bottom of the other quick-connection mechanism 5, and an anti-blocking mechanism 4 is provided in the well point pipe 6;

[0030] The anti-blocking mechanism 4 includes a rotating rod 402, the outer walls of which are respectively connected to multiple propellers 403 and multiple blades 404, the two ends of the rotating rod 402 are respectively rotatably connected to a filter plate 405 and a connecting block 401, and one end of the rotating rod 402 passes through one side of the filter plate 405, and the outer wall of the rotating rod 402 is connected to two scrapers 406, the outer wall of the filter plate 405 is connected to the inner wall of the well-point pipe 6, both sides of the connecting block 401 are connected to the inner wall of the well-point pipe 6, the top of the scraper 406 is in contact with the bottom of the filter plate 405, and one side of the scraper 406 is slidably connected to the inner wall of the well-point pipe 6.

[0031] The specific implementation method is as follows: water enters the well point pipe 6 through the pump room 1, and the rising water flow drives the propeller 403 to rotate, and the rotation of the propeller 403 drives the rotating rod 402 to rotate, and the rotation of the rotating rod 402 drives the blade 404 to rotate, so that the mud and impurities that cannot be filtered by the filter plate 405 can be further crushed, avoiding the blockage of the pipe caused by large mud and impurity particles, so that the equipment can work normally. When the rotating rod 402 rotates, the rotating rod 402 will also drive the scraper 406 to rotate. Since the scraper 406 is tightly fitted with the filter plate 405, the scraper 406 can clean up the impurities and soil attached to the surface of the filter plate 405, avoiding the blockage of the filter plate 405 and the blockage of the well point pipe 6.

[0032] The outer wall of the main pipe 7 is connected with a first connecting pipe 8, the other end of the first connecting pipe 8 is connected with a pump room 1, and the other side of the pump room 1 is connected with a water outlet pipe 2. The outer wall of the main pipe 7 is connected with a plurality of second connecting pipes 10, and the second connecting pipe 10 and one end of the well point pipe 6 are both connected with a joint 9, and a limiting groove 11 is provided on the outer wall of the joint 9. The quick connection mechanism 5 includes a fixed ring 501, the inner wall of the fixed ring 501 is connected to the outer wall of the bent connecting pipe 3, and a sliding sleeve 502 is slidably connected to the outer wall of the bent connecting pipe 3. A spring groove 504 and a placement groove 507 are respectively provided on both sides of the sliding sleeve 502. The inner wall of the spring groove 504 is slidably connected to the outer wall of the fixed ring 501. A spring 503 is provided on the outer wall of the bent connecting pipe 3, and the two ends of the spring 503 are respectively connected to one side of the fixed ring 501 and the inner wall of the spring groove 504. A plurality of travel grooves 505 are provided on the outer wall of the bent connecting pipe 3, and the inner wall of the travel groove 505 is slidably connected to a limiting ball 506, and the inner wall of the bent connecting pipe 3 is slidably connected to the outer wall of the joint 9.

[0033] The specific implementation method is as follows: the sliding sleeve 502 moves upward to compress the spring 503, and at the same time drives the placement groove 507 to move, so that the placement groove 507 moves to a position horizontal with the limiting ball 506. At this time, the joint 9 is inserted into the curved connecting pipe 3. During the insertion of the joint 9, the side of the outer wall of the joint 9 with an inclined surface will push the limiting ball 506, so that the limiting ball 506 moves into the placement groove 507 through the travel groove 505, so that the joint 9 can continue to be inserted. When the limiting groove 11 moves to a position horizontal with the limiting ball 506, the sliding sleeve 502 is driven downward by the elastic force of the spring 503 to return to its original position, so that the side of the placement groove 507 with an inclined surface squeezes the limiting ball 506, so that the limiting ball 506 moves into the limiting groove 11 through the travel groove 505, so that the joint 9 is stuck by the limiting ball 506, and then the well point pipe 6 and the second connecting pipe 10 are connected to the curved connecting pipe 3 through the joint 9, so that the connection operation is relatively simple, the connection speed is fast, and the work efficiency is improved.

[0034] Working principle: When in use, the well point pipe 6 is inserted into the ground, and the sliding sleeve 502 slides backward to drive the placement groove 507 to move backward to the position of the travel groove 505, and the spring 503 is compressed, and then the curved connecting pipe 3 is moved downward, so that the joint 9 is inserted into the curved connecting pipe 3. During this process, the joint 9 first moves the limiting ball 506 into the placement groove 507, and then the spring 503 stretches to drive the sliding sleeve 502 to move downward, and drives the limiting ball 506 to move into the limiting groove 11, so that the limiting ball 506 passes The limiting groove 11 fixes the joint 9, thereby connecting the bent pipe 3, the well point pipe 6 and the main pipe 7. Then, water is sucked into the well point pipe 6 through the pump room 1. The water flows upward in the well point pipe 6 and drives the propeller 403 to rotate. The rotation of the propeller 403 drives the blade 404 and the scraper 406 to rotate. The rotation of the blade 404 crushes the mud and impurities in the well point pipe 6. The rotation of the scraper 406 cleans up the mud and impurities on the surface of the filter plate 405. Both prevent the mud and impurities from clogging the well point pipe 6.
