DETAILED DESCRIPTION

A fixing seat 2 is installed at the bottom of the multistage pump group 1, and a filter chamber group 3 is installed at the top of the multistage pump group 1, and a filter assembly 4 is installed inside the filter chamber group 3. The water inlet section group 5 is symmetrically connected to the top of the filter chamber group 3. The water inlet section group 5 includes an inner spiral tube 501, a connecting tube 502, a regulating valve 503 and a movable tube 504. The top of the inner spiral tube 501 is provided with a connecting tube 502, and the lower end of the inner spiral tube 501 is provided with a regulating valve 503, and the bottom of the regulating valve 503 is connected with a movable tube 504. Through the structural setting of the inner spiral tube 501, the water flow entering therein is increased in flow rate with the assistance of the spiral structure inside it, and through the structural setting of the movable tube 504, the entire water inlet section group 5 can be swung left and right in the vertical direction at the top of the filter chamber group 3, so that it can be adjusted within a certain range according to the needs of use, so as to facilitate structural adjustment in different scenarios.
[0025] The multistage pump assembly 1 includes a multistage pump body 101, a coupling 102 and an assembly flange 103. The coupling 102 is installed at one end of the multistage pump body 101, and the assembly flange 103 is arranged on the top of the multistage pump body 101. The filter chamber assembly 3 includes a strengthening chamber 301, an adjusting pipe 302 and a fixing flange 303. The side of the strengthening chamber 301 is rotatably connected with the adjusting pipe 302, and the end of the adjusting pipe 302 away from the strengthening chamber 301 is installed with a fixing flange 303. The structures of the fixing flange 303 and the assembly flange 103 match each other, and the assembly flange 103 and the multistage pump body 101 are fixedly connected. The fixed connection, the adjusting tube 302 enables the strengthening chamber 301 to have the activity of horizontal axial rotation, and the inner spiral tube 501 when the movable tube 504 has the activity of horizontal axial rotation on the side of the strengthening chamber 301. Through the use of the assembly flange 103 and the fixed flange 303, the entire multi-stage pump group 1 and the filter chamber group 3 have good structural disassembly properties, so as to facilitate the structural maintenance of the filter assembly 4 installed inside the filter chamber group 3. In addition, through the use of the adjusting tube 302, the entire strengthening chamber 301 can have axial rotation properties in the horizontal direction, thereby further improving the activity of the entire device structure.
[0026] The filter assembly 4 includes a filter screen 401, a slide tube 402 and a guide rod 403. The left and right sides of the filter screen 401 are symmetrically connected with the slide tube 402, and the middle section of the slide tube 402 is vertically penetrated by the guide rod 403. The filter assembly 4 also includes a return spring 404 and a fixed column 405. The bottom of the slide tube 402 is provided with a return spring 404. The upper and lower ends of the guide rod 403 are slidably connected between the slide tube 402 and the guide rod 403, and the return spring 404 is sleeved on the lower section surface of the guide rod 403. When water flows into the filter through the water inlet section group 5 When the water is inside the bin group 3, the impurities contained in the water will be intercepted by the filter screen 401. At the same time, due to the rapid flushing of the water flow, the filter screen 401 is pushed along the guide rod 403 toward the direction of the return spring 404 through the sliding tube 402 and squeezes the return spring 404. The return spring 404 compressed by the structure will rebound at the same time. This reciprocating movement allows the entire filter screen 401 to elastically move up and down inside the reinforced bin 301, which can filter out impurities in the passing water as much as possible without affecting the flow rate of the water.
[0027] In summary, if Figures 1 to 4 As shown, when the double-inlet double-helix high-efficiency water inlet section is used, the whole device is first fixed on a pre-confirmed installation structure surface by using the fixing seat 2 provided at the bottom of the multistage pump group 1, and then the assembly flange 103 provided at the top of the multistage pump body 101 is connected and fixed with the fixing flange 303 provided at the bottom of the regulating pipe 302, and the coupling 102 is used to connect the whole multistage pump group 1 with the motor used for external power drive;
[0028] During the installation process, the structural rotation between the strengthening chamber 301 and the adjusting pipe 302 can be adjusted by the water inlet section group 5 connected to the top of the entire filtering chamber group 3 communicating vessel to be able to rotate left and right in the vertical direction, so as to make appropriate adjustments according to the needs of pipeline laying and connection;
[0029] Then, the rotational mobility between the movable pipe 504 and the strengthening chamber 301 is used to adjust the connection direction of the entire water inlet section group 5, so as to facilitate the subsequent pipeline connection. Finally, the external water delivery pipeline is connected and fixed to the water inlet section group 5 through the connecting pipe 502.
[0030] When water enters the interior of the enhanced chamber 301 through the inner spiral tube 501, the filter screen 401 will be pushed by the water pressure as the high-speed water flow is flushed, and moves along the surface of the guide rod 403 under the sliding of the sliding tube 402, and is pushed toward the output end of the regulating tube 302, thereby squeezing the reset spring 404. The reset spring 404 will rebound while being structurally compressed, so that the filter screen 401 can reciprocate inside the filter chamber group 3, thereby ensuring that the water flowing through it is filtered and impurities removed to the greatest extent.
