[0002] A water pump refers to a pump with one suction (water) nozzle and one exhaust (water) nozzle, and can continuously form a vacuum or negative pressure at the inlet; a slight positive pressure is formed at the exhaust nozzle, and the diaphragm inside the pump is made to move back and forth through a mechanical device, thereby compressing and stretching the air in the pump chamber of a fixed volume to form a vacuum (negative pressure), and creating a pressure difference between the pump suction port and the external atmospheric pressure. Under the action of the pressure difference, the gas is compressed (sucked) into the pump chamber and then discharged from the exhaust port.

[0003] At present, when a water pump is pumping liquid, it is impacted by hydraulic pressure. The inner cavity of the water pump is not easy to accumulate dirt, but the water pumping pipe directly connected to the pump body is easily disturbed by foreign objects and becomes scratched or blocked. When the equipment stops running, the dirt that is not washed away by the water pressure will adhere to the pipe wall, and in severe cases will cause corrosion to the pipe.

[0004] Regarding the operation of the water pump, how to prevent external dirt from damaging the pipes connected to the water pump in order to increase the service life of the pipes is a technical difficulty that needs to be solved. Utility Model Content

[0034] Specifically, the water pump 120 is installed on the outside of the transmission motor 110, and the transmission shaft inside the transmission motor 110 is adapted to penetrate into the inner cavity of the water pump 120, the drainage pipe 220 is installed on the outer end of the adapter end pipe 210, the base 230 is installed on the bottom end of the drainage pipe 220, the nut 260 is connected to the outside of the base 230, the anti-blocking member 250 is connected to the inside of the flow delivery base 240, the nut 260 is installed on the outer end of the anti-blocking member 250, and the two clamp seats 310 are respectively installed on the drainage pipe 220 and the drainage pipe 220. On the water pipe 220 and the base 230, the first clamping plate 320 is installed on the guide rod on one side of the clamping seat 310, and the second clamping plate 330 is installed on the guide rod on the other side of the clamping seat 310. The winding roller 350 is located on the inner side of the first clamping plate 320 and the second clamping plate 330. The rocker 340 is installed inside the winding roller 350. The pin 380 is movably installed inside the rocker 340. The cable 360 is wound around the outside of the two winding rollers 350, and the dredging assembly 370 is installed outside the cable 360.

[0035] Two clamping seats 310 are fixedly installed in the drain pipe 220 and the base 230 respectively, and the first clamping plate 320 and the second clamping plate 330 are symmetrically installed on the end rods on both sides of the clamping seats 310, and the rocker 340 and the winding roller 350 are movably installed on the inner sides of the adjacent first clamping plate 320 and the second clamping plate 330. At the same time, the two ends of the cable 360 are respectively wrapped around the outside of the two winding rollers 350, and the combined dredging assembly 370 is fixedly installed on the cable 360. When a rocker 340 close to the base 230 is controlled to rotate, the cable 360 will drive the dredging assembly 370 to move along the inner wall of the drain pipe 220 until the dirt adhered to the inner wall of the drain pipe 220 is quickly scraped off by the dredging assembly 370. At this time, the device can normally extract sewage while avoiding the problem of corrosion of the pipe wall due to excessive dirt adhesion. Embodiment 2

[0036] Combination Figure 2-Figure 4As shown, on the basis of the first embodiment, the outer end of the base 230 and the inner end of the fluid delivery base 240 are respectively installed with evenly distributed pressure pads, and the inner part of the pressure pads is movably installed with a combination bolt, the anti-blocking member 250 is composed of a filter sheet and an end rod, and the end of the end rod that passes through the outside of the fluid delivery base 240 is provided with a thread adapted to engage with the nut 260.

When the flow delivery base 240 and the base 230 are immersed in the interior of the foundation ditch, the sewage will enter from the notch inside the flow delivery base 240 in advance, and enter the inner cavity of the drainage pipe 220 after being filtered by the anti-blocking member 250, and finally be extracted upward by the water pump 120 until the sewage is discharged outward along the water outlet end pipe at the top of the water pump 120, thereby ensuring that the device can quickly pump water from the foundation of the security project. Embodiment 3

[0038] Combination Figure 5-Figure 7 As shown, on the basis of Example 1, a hollow cavity is opened inside the clamp seat 310, and the cable 360 is adapted to pass through the hollow cavity, and the dredging assembly 370 includes a reinforcing gasket 371 fixedly installed on the outside of the cable 360, two sealing gaskets 372 movably installed in two annular grooves outside the reinforcing gasket 371, and an annular scraper 373 installed in the reinforcing gasket 371, and a funnel-shaped blade head is installed at one end of the annular scraper 373 away from the reinforcing gasket 371, and a plurality of plug rods that pass through the inside of the reinforcing gasket 371 are fixedly installed on the inner side of the annular scraper 373.

[0039] By fixing the reinforcing gasket 371 on the outside of the cable 360, in the initial state, a flow delivery base 240 close to the adapter end pipe 210 is pre-adjusted until an anti-blocking member 250 installed on the outside thereof reels the cable 360, and then the latch 380 is inserted into the rocker 340 and the first clamping plate 320, and the dredging assembly 370 as a whole can be moved into the pipe at the top of the drain pipe 220. When the drain pipe 220 completes the extraction of sewage from the foundation ditch, the operator can remove the latch 380 again and control another rocker 340 close to the base 230 to rotate until the cable 360 drives the dredging assembly 370 to move along the inner cavity of the drain pipe 220. At this time, the dirt adhering to the inner wall of the drain pipe 220 can be quickly cleaned, thereby effectively ensuring that the device can be safely stored after use.

[0040] The working principle and use process of the utility model are as follows: two sealing gaskets 372 are pre-installed in two annular grooves outside the reinforcing gasket 371, and then the annular scraper 373 is installed at one end of the reinforcing gasket 371, and the annular scraper 373 is penetrated into the rod body inside the reinforcing gasket 371 by using multiple nuts to lock it. At this time, the annular scraper 373 can be tightly fitted on the reinforcing gasket 371, and the reinforcing gasket 371 is fixedly installed on the outside of the cable 360, and then the two clamping seats 31 0 are respectively fixedly installed in the drain pipe 220 and the base 230, and the first clamping plate 320 and the second clamping plate 330 installed on the rod bodies on both sides of the clamping seat 310 can position and clamp the combined winding roller 350 and the rocker 340, and the two ends of the cable 360 will be respectively wound around the outside of the two winding rollers 350, and then the two rockers 340 are adjusted until the cable 360 is in a taut state in the inner cavity of the drain pipe 220, and the dredging assembly 370 will be located in the cavity at the top of the drain pipe 220;

[0041] When in use, the operator needs to install the adapter end pipe 210 on the end pipe outside the water pump 120 in advance, and place the combined flow base 240 and drainage pipe 220 in the ditch of the foundation until the flow base 240 and drainage pipe 220 are immersed in the sewage in the ditch of the foundation. When the transmission motor 110 is started and running, as the sewage in the ditch enters the inner cavity of the flow base 240 and the base 230, the sewage can be screened by the anti-blocking member 250, and the finally treated sewage can enter the interior of the water pump 120 along the drainage pipe 220 and The water is discharged outward from the water outlet pipe at the top of the water pump 120. When the equipment is stopped, the two pins 380 are removed, and then the operator can adjust a rocker 340 near the base 230 until the cable 360 drives the dredging assembly 370 to move along the inner cavity of the drain pipe 220, until the dredging assembly 370 scrapes the dirt accumulated on the inner wall of the drain pipe 220 to the inside of the base 230. When the dirt is submerged in the base 230, the base 230 can be placed in water for washing, thereby ensuring the convenient cleaning of the drain pipe 220 after use.

[0042] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
