[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a municipal water conservancy engineering screen includes a support base 1, a connecting frame 2 rotatably connected to the support base 1, a screen 3 fixedly connected to the connecting frame 2, a cleaning structure 4 on the support base 1, the cleaning structure 4 including a long pipe 401 and a nozzle 402, two long pipes 401 fixedly connected to the support base 1, multiple nozzles 402 installed on the long pipes 401, a short pipe 403 fixedly connected to one end of the long pipes 401, a water tank 407 fixedly connected to the support base 1, a booster pump 405 installed on the water tank 407, a first connecting pipe 404 fixedly connected to the booster pump 405, two short pipes 403 fixedly connected to the first connecting pipe 404, a second connecting pipe 406 fixedly connected to the booster pump 405, the end of the second connecting pipe 406 extending into the interior of the water tank 407, an inlet pipe 408 fixedly connected to the water tank 407, and a driving structure 6 on the support base 1.

[0023] As a technical optimization solution of this utility model, such as Figure 1As shown, multiple nozzles 402 located on the same long tube 401 are linearly and equidistantly distributed, and the screen 3 is inclined, so that impurities inside the screen 3 can easily fall into the collection box 702 for collection.

[0024] As a technical optimization solution of this utility model, such as Figure 1 and Figure 2 As shown, a water supply pipe 8 is fixedly connected to the support base 1, and a drain pipe 9 is fixedly connected to the support base 1. Therefore, sewage can enter the interior of the screen 3 from the water supply pipe 8 and be discharged from the interior of the support base 1 through the drain pipe 9.

[0025] As a technical optimization solution of this utility model, such as Figure 2 and Figure 4 As shown, the drive structure 6 includes a motor 601 and a first pulley 602. The motor 601 is mounted on the support base 1. The first pulley 602 is fixedly connected to the output shaft of the motor 601. The second pulley 604 is fixedly connected to the connecting frame 2. A belt 603 is wound between the first pulley 602 and the second pulley 604, which enables the screen 3 to rotate, thereby improving the filtration and screening effect.

[0026] As a technical optimization solution of this utility model, such as Figure 1 , Figure 3 and Figure 6 As shown, the short pipe 403 is provided with a filter structure 5, which includes a retaining ring 501 and a connecting ring 502. The retaining ring 501 is fixedly connected inside the short pipe 403, and the connecting ring 502 abuts against the retaining ring 501. A filter screen 503 is fixedly connected to the connecting ring 502. Therefore, water can be filtered through the filter screen 503, thereby preventing large particles of impurities in the water from clogging the nozzle 402 and improving the stability of use.

[0027] As a technical optimization solution of this utility model, such as Figure 3 As shown, a pressure sleeve 506 abuts on the connecting ring 502, and a threaded sleeve 505 is threadedly connected to the short tube 403. The threaded sleeve 505 abuts against the retaining ring 501, and the threaded sleeve 505 abuts against one end of the short tube 403. Therefore, the filter screen 503 can be quickly disassembled, which facilitates the cleaning of the filter screen 503.

[0028] As a technical optimization solution of this utility model, such as Figure 3 As shown, a plurality of rotating rods 504 are fixedly connected to the threaded sleeve 505. The plurality of rotating rods 504 are arranged in a circular array about the center of the threaded sleeve 505, so the threaded sleeve 505 can be easily rotated by holding the rotating rods 504.

[0029] As a technical optimization solution of this utility model, such as Figure 1 and Figure 2 As shown, the bottom end of the support base 1 is provided with a collection structure 7, which includes a handle 701 and a collection box 702. The bottom end of the support base 1 is provided with a collection box 702, and a handle 701 is fixedly connected to one side of the collection box 702. Four brake casters 703 are installed at the bottom end of the collection box 702, thus enabling the centralized collection of impurities after screening and filtration.

[0030] In use, the external water delivery pipe can be connected to the inlet pipe 408, and the sewage delivery pipe can be connected to the supply pipe 8. Water then enters the screen 3 from the supply pipe 8. Larger impurities are blocked by the screen 3 and eventually fall into the collection box 702 for collection. The filtered sewage flows to the bottom of the support base 1 and is finally discharged from the drain pipe 9. During the filtration and screening process, the motor 601 can be started. The output shaft of the motor 601 rotates, driving the first pulley 602 to rotate. The first pulley 602 drives the second pulley 604 to rotate via the belt 603. The rotation of the second pulley 604 drives the connecting frame. 2. Rotation of connecting frame 2 will cause screen 3 to rotate. This rotation allows each part of screen 3 to perform sieving, thus improving the filtration and sieving effect. When cleaning screen 3 is needed, water enters water tank 407 through inlet pipe 408. Then, booster pump 405 is activated. Under the action of booster pump 405, water enters the second connecting pipe 406, then the booster pump 405, then the first connecting pipe 404, then the two short pipes 403, and finally the long pipe 403. Inside the nozzle 1, the water is finally sprayed out from multiple nozzles 402. Under the action of the booster pump 405, the water sprayed from the nozzles 402 has a large pressure. After the high-pressure water comes into contact with the screen 3, it will backwash the screen 3. During the washing process, the motor 601 can drive the connecting frame 2 to rotate. The rotation of the connecting frame 2 will drive the screen 3 to rotate together, thereby achieving a comprehensive and rapid cleaning of the screen 3. This avoids the need for manual cleaning by personnel, effectively shortens the cleaning time, and improves the cleaning efficiency. It is worth noting that during the flow of water inside the short pipe 403, it can be filtered through the filter screen 503, thereby preventing large particles of impurities in the water from clogging the nozzles 402. The plug improves the stability of use. When the filter screen 503 needs to be cleaned, the threaded sleeve 505 can be rotated by holding the rotating rod 504 until the threaded sleeve 505 is unscrewed from the end of the short tube 403. Then the pressure sleeve 506 is taken out, and finally the filter screen 503 is taken out, thus realizing the quick disassembly of the filter screen 503, which facilitates the cleaning of the filter screen 503 and effectively ensures the filtration effect of the filter screen 503. When it is necessary to clean the impurities collected inside the collection box 702, the brake of the brake universal wheel 703 can be released, and then the collection box 702 can be pulled out from the bottom of the support base 1 by holding the handle 701. After the collection box 702 is pulled out, it is convenient to clean the impurities collected inside.
