[0032] The sealing mechanism 3 is arranged at the top of the water inlet pipe 24. The sealing mechanism 3 includes a positioning tube 31. The positioning tube 31 is installed at the top of the water inlet pipe 24 and is connected with the water inlet pipe 24. A sealing cover 32 is installed on the top of the positioning tube 31. A transmission hole 321 is opened on the top of the sealing cover 32. An air supply pipe 22 is clamped on the top of the sealing cover 32. The other end of the air supply pipe 22 is connected with the vacuum chamber 2. The dredging mechanism 4 is installed at the port of the water inlet pipe 24. When a water pump is needed, as the control motor 12 starts to run, it can play a role in pumping water, which is convenient for subsequent irrigation of farmland, and as the pumping During the watering process, the dredging mechanism 4 can be used to block and separate, and prevent leaves and impurities from entering the diversion chamber 21, which can extend the maintenance period of the equipment and reduce blockages. As the equipment is in operation, the internal airflow of the vacuum chamber 2 can be used to quickly extract excess gas from the diversion chamber 21, so that the interior is in a negative pressure state, and external water can flow in through the diversion pipe connected to the water inlet pipe 24. At this time, the guide wheel at one end of the rotating shaft rotates, and the water can be discharged along the outlet pipe 23, which is convenient for subsequent irrigation treatment.

When an unexpected situation occurs during operation, the floating terminal 33 can be pressed against the transmission hole 321 to prevent water from entering the vacuum chamber 2 and causing damage to the equipment.

[0034] like Figure 8As shown, since dirt and the like are often mixed in the water and remain inside the positioning tube 31, a pair of clamping shafts 331 are installed on the side walls of the floating terminal 33. The clamping shafts 331 are arc-shaped and symmetrically installed at both ends of the floating terminal 33. A gap is provided between the outer wall of the clamping shaft 331 and the inner wall of the positioning tube 31. A connecting shaft 341 is installed at the bottom of the floating terminal 33.

[0035] like Figure 7 As shown, the bottom of the blocking cover 34 is fixedly connected to a swing shaft 35, and a counterweight ball 351 is installed at the bottom of the swing shaft 35. A fixing ring is installed on the side wall of the counterweight ball 351, and the fixing ring is made of rubber. The cleaning plate 44 can collide with the counterweight ball 351, and can pull the floating terminal 33 to move on the liquid surface. The inner wall of the positioning tube 31 can be cleaned with the help of the blocking cover 34 to prevent small dirt or algae fragments from entering the interior of the positioning tube 31 and affecting the operation of subsequent equipment. The adsorption shaft 46 on the cleaning plate 44 can move with the counterweight ball 351, so as to cooperate with the elastic barbs to further clean and adsorb the suspended dirt in the water flow.

[0036] like Figure 2 As shown, in order to reduce the situation where dirt and the like enter the inside of the water pump during operation, the dredging mechanism 4 includes a positioning ring 41 and a fixed pipe 42. The positioning ring 41 is clamped inside the water inlet pipe 24. A plurality of metal rods are installed on the inner wall of the positioning ring 41. The fixed pipe 42 is installed between the metal rods, and the metal rods are symmetrically arranged. A fixed sieve plate is installed between the positioning ring 41 and the fixed pipe 42 to separate solid impurities in sewage. The fixed sieve plate can play a separation role to prevent dirt and the like in the water flow from entering the inside of the vertical plate, which is used to block dirt and ensure the normal operation of the equipment.

[0037] like Figure 5 As shown, during the operation of the equipment, a small amount of dirt will enter the water pump and be adsorbed on the internal parts. The dredging mechanism 4 also includes a rotating shaft 43, which is rotatably arranged inside the fixed pipe 42. The two ends of the rotating shaft 43 are respectively installed with a movable disc 45 and a cleaning plate 44. The cleaning plate 44 is located inside the water inlet pipe 24, and the movable disc 45 is rotatably arranged on the outside of the fixed screen plate.

[0038] One end of the cleaning plate 44 is arc-shaped, and a plurality of adsorption shafts 46 are fixedly connected to one side of the arc-shaped cleaning plate 44. A plurality of elastic barbs are provided on the inner wall of the adsorption shaft 46. The position of the cleaning plate 44 corresponds to the counterweight ball 351. During the rotation of the cleaning plate 44 following the rotating shaft 43, the adsorption shaft 46 can be used to adsorb small suspended particles in the water, thereby reducing the amount of suspended dirt in the sewage and reducing the corrosion caused by the accumulation of dirt on the surface of internal parts.

[0039] like Figure 3 and Figure 4 As shown, in order to prevent the accumulation of dead branches and broken leaves, etc., which may cause the water absorption process to be not smooth, a plurality of arc grooves are provided on the movable disk 45 for rotating with the water flow, an annular groove is provided on the outer wall of the movable disk 45, and a reset shaft 451 is connected inside the annular groove, the reset shaft 451 is elastic, a cleaning block 47 is clamped on the reset shaft 451, the cleaning block 47 is arc-shaped and has a hollow groove inside, a plurality of sewage inlet grooves 471 are installed on the top of the cleaning block 47, a pair of limiting shafts 472 are installed on the inner wall of the cleaning block 47, an adsorption plate 48 is clamped inside the limiting shaft 472, and the adsorption plate 48 The position corresponds to the sewage inlet trough. The cleaning block 47 on the edge of the movable disk 45 can be arranged in contact with the inner wall of the external guide tube under the action of centrifugation, and can clean the pipeline connection port during the transmission process to prevent silt and debris in the water from accumulating in the pipeline to reduce the water flow of the pipeline. The dirt generated enters the adsorption plate 48 along the sewage inlet trough 471, which can be convenient for subsequent replacement and cleaning. In addition, as the cleaning block 47 moves, dead branches and leaves can also be squeezed and torn off, which can reduce the accumulation of dirt on one side of the fixed screen plate, resulting in a reduction in water intake.

[0040] Preferably, a sound-absorbing pad is installed at the bottom of the fixing frame 1, and the sound-absorbing pad is made of rubber material, which can play a shock-absorbing role and reduce the noise caused by vibration during the operation of the equipment.

[0041] Working principle: First, when the water pump is needed, as the control motor 12 starts to operate, it can play a role in pumping water, which is convenient for subsequent irrigation of farmland, and during the pumping process, the dredging mechanism 4 can play a role in blocking and separating, preventing leaves and impurities from entering the diversion chamber 21, which can extend the maintenance cycle of the equipment and reduce blockages. During the operation of the equipment, the internal airflow of the vacuum chamber 2 can be used to quickly extract the excess gas in the diversion chamber 21, so that the interior is in a negative pressure state, and the external water flow can enter along the diversion pipe connected to the water inlet pipe 24. At this time, the guide wheel at one end of the rotating shaft rotates, and the water flow can be discharged along the outlet pipe 23, which is convenient for subsequent irrigation treatment. With the help of the water flow and the arc groove on the movable disk 45, the movable disk 45 can rotate with the water flow, and the dead branches and broken leaves can be squeezed and separated during the transmission process to prevent them from directly sticking to the fixed screen plate and affecting the entry amount.

[0042] Then, during the transmission process, the cleaning block 47 on the edge of the movable disk 45 can be arranged in contact with the inner wall of the external guide tube under the action of centrifugation, and can clean the pipe connection port during the transmission process to prevent sludge and debris in the water from accumulating in the pipe and reducing the water flow of the pipe, and the generated dirt and the like enter the adsorption plate 48 along the sewage inlet trough 471, which can be convenient for subsequent replacement and cleaning, and as the cleaning block 47 moves, it can also squeeze and tear off dead branches and leaves, which can facilitate subsequent irrigation cleaning and maintenance, and the cleaning plate 44 can absorb small suspended particles in the water with the help of the adsorption shaft 46 during the rotation of the rotating shaft 43, so as to prevent it from floating in the positioning tube 31 under the action of buoyancy, and long-term use will cause residues in the positioning tube 31, which can slow down the accumulation of scale and stains in the guide chamber 21;

[0043] Finally, the cleaning plate 44 can collide with the counterweight ball 351, which can pull the floating terminal 33 to move on the liquid surface, and the inner wall of the positioning tube 31 can be cleaned with the help of the blocking cover 34 to prevent small dirt or algae fragments from entering the positioning tube 31 and affecting the operation of subsequent equipment. After the irrigation is completed, the equipment can be stopped and the floating terminal 33 can be reset to allow the dirt adhered to the bottom of the blocking cover 34 to be discharged along the water flow, thereby extending the maintenance cycle inside the equipment.
