Description

Technical Field

[0001] The present invention relates to the technical field of sewage pumps, and more particularly to a high-performance sewage pump. Background Art

[0002] The working principle of the sewage pump is based on the pressure difference and centrifugal force. When the sewage pump is started, the motor drives the impeller to rotate. The rotation of the impeller generates centrifugal force, causing the sewage to enter the pump body. As the impeller rotates, the sewage is sucked into the inlet of the pump body. At the same time, the pressure in the pump body decreases, forming a negative pressure area, which prompts the sewage to continue to be sucked in. After the sewage enters the pump body, the rotation of the impeller pushes it to the outlet. The centrifugal force causes the sewage to be quickly pumped out and transported to the target location.

[0022] The crushed pulp is drivingly connected to the output shaft of the sewage pump motor 3, and the guide rod 10 is slidably connected to the guide hole at the corresponding position.

[0023] The lifting screw 13 is disposed in the lifting screw hole, and the lifting screw 13 is drivingly connected to the output shaft of the lifting motor 12 .

[0024] The cross-sectional shape of the guide bar 21 in a top view is set to be T-shaped, and the cross-sectional shape of the guide groove 24 in a top view is set to be T-shaped, and the guide groove 24 matches the shape of the guide bar.

[0029] The single chip microcomputer model is set to M68HC16, and the flow sensor model is set to WG311.

[0030] The specific implementation method is as follows: when using the present invention, the start and stop of the device can be controlled by the suction start button 34 and the suction stop button 35, so that the pump itself can be operated and closed. The discharge port flow sensor 7 will detect the liquid flow inside the discharge port 5 in real time. When the flow value decreases significantly, the intelligent control unit 27 determines that there is a blockage problem in the liquid inlet 8. At this time, the intelligent control unit 27 controls the sewage pump motor 3 to close, so that the pump itself stops running. Then the intelligent control unit 27 automatically controls the lifting motor 12 to drive the lifting screw 13 to rotate, which will drive the pump body 1 to rise, and the guide rod 10 will move in the guide hole, thereby realizing the guiding and limiting functions. After rising to a suitable height, the intelligent control unit 27 stops the lifting motor 12 and starts the posture adjustment electric push rod 26, whose output shaft pushes the transmission rod 25 to extend. The extension of the transmission rod 25 will push the cleaning motor 16 to deflect upward, and at the same time, the slide 23 slides downward on the guide bar 21. When the cleaning motor 16 is pushed to vertical, the posture adjustment electric push rod 26 just reaches the limit distance of the output shaft extension. At this time, the intelligent control unit 27 The posture adjustment electric push rod 26 is closed, and the lifting motor 12 is controlled to rotate in the opposite direction, so that the pump body 1 descends until the cleaning bracket 18 is inserted into the liquid inlet 8. At this time, the intelligent control unit 27 controls the lifting motor 12 to close and start the cleaning motor 16. The cleaning motor 16 drives the cleaning bracket 18 to rotate through the cleaning shaft 17. The plastic cleaning brush strip 19 and the sponge wiping strip 20 cooperate with each other to remove the accumulated dirt on the inner wall of the liquid inlet 8, thereby ensuring that the liquid inlet 8 is unobstructed. After cleaning, the intelligent control unit 27 controls the device to reset. The principle is the same as above, and then the intelligent control unit 27 continues to start the sewage pump motor 3 to make the device run. By pressing the cleaning button 31, the automatic cleaning of the liquid inlet 8 can be manually controlled. The suction height of the device can be manually adjusted by the suction position lowering button 33 and the suction position raising button 32. This enables the present invention to automatically clean the liquid inlet 8 according to the discharge volume, avoiding the problem that the dirt accumulation in the liquid inlet 8 causes blockage and affects the operation of the sewage pump. No manual cleaning is required, the cleaning efficiency is high, and the degree of automation is high, so that the actual use effect of the present invention is better.

[0031] Working principle of the present invention: Refer to the instruction manual Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 5 When using the present invention, by providing a discharge port flow sensor 7, an intelligent control unit 27, a cleaning motor 16 and a posture adjustment electric push rod 26 and other structures, the present invention can automatically clean the liquid inlet 8 according to the discharge volume, avoiding the problem of dirt accumulation at the liquid inlet 8 causing blockage that affects the operation of the sewage pump. No manual cleaning is required, the cleaning efficiency is high, and the degree of automation is high, so that the actual use effect of the present invention is better.
