[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0022] Example:

[0023] like Figures 1 to 4 As shown, this utility model provides a drainage pump with water level control function, including a pump body 11 and a volute 12. The volute 12 is located at the bottom of the pump body 11, and has an inlet pipe 15 and a drain pipe 16. A filter 17 is installed inside the inlet pipe 15, which can intercept impurities. The pump body 11 is equipped with a backwash assembly, which includes a backwash pump 18 and two sets of first control valves 19. The inlet pipe 15 and the drain pipe 16 are connected by a pipeline, and the backwash pump 18 is also connected to the pipeline. This connection enables backwashing and improves the self-cleaning ability of the filter 17. The two sets of first control valves 19 are respectively installed on the inlet pipe 15 and the drain pipe 16, and the forward and reverse water flow can be adjusted through the dual-valve linkage control. A suction port 21 is provided on the drain pipe 16, and a second control valve 22 is provided on the suction port 21. A pump cover 23 is provided on the top of the pump body 11. Through the cooperation of the suction port 21 and the second control valve 22, the suction function can be realized, and the opening and closing of the backwash cleaning can be controlled. A control module 24 is provided inside the pump cover 23. Both the first control valve 19 and the second control valve 22 are electrically connected to the control module 24. Through the setting of the control module 24, the device can be controlled. The control module 24 can be an LPC1768FBD100 microcontroller.

[0024] A water level control module 25, electrically connected to the control module 24, is housed inside the pump cover 23. A water level sensor 26 is mounted on the pump body 11 and is electrically connected to the water level control module 25. Through feedback settings from the water level sensor 26, changes in liquid level can be monitored. The water level control module 25 can be an E5AC-CX model, and the water level sensor 26 can be an L2-1000 model.

[0025] The pump body 11 is equipped with a mounting bracket 27, and the backwash pump 18 is mounted on the mounting bracket 27. The inlet of the backwash pump 18 is connected to the drain pipe 16, and the outlet of the backwash pump 18 is connected to the inlet pipe 15. The fixed setting of the mounting bracket 27 can stabilize the operating posture of the backwash pump 18 and improve the durability of the equipment.

[0026] like Figure 2 , 3 As shown, the water inlet pipe 15 is equipped with an end cap 29 and a connector for adjusting the opening and closing of the end cap 29. The end cap 29 is connected to the water inlet pipe 15 via the connector. The water suction port 21 is equipped with a filter end cap 31. The opening and closing of the water inlet pipe 15 can be controlled by adjusting the end cap 29. The filter end cap 31 is used to prevent impurities from entering the filter.

[0027] The connector includes a sleeve 32 and a suspension ball 33. The sleeve 32 is mounted on the inlet pipe 15, and the end cap 29 is slidably mounted inside the sleeve 32. Through the guiding mechanism of the sleeve 32, the end cap 29 can adaptively rise and fall, improving sealing adjustment efficiency. The suspension ball 33 is installed on the top of the end cap 29, and a pressure sensor 34 is located on the top of the sleeve 32. The pressure sensor 34 is electrically connected to the control module 24. Through the linkage between the suspension ball 33 and the pressure sensor 34, changes in water level buoyancy can be sensed, improving overflow protection capabilities. The pressure sensor 34 can be an MLH model pressure sensor.

[0028] The end cap 29 has a groove 35, and a slider 36 is provided on the end cap 29. The slider 36 is slidably disposed within the groove 35. The cooperation between the groove 35 and the slider 36 restricts the movement of the end cap 29, improving structural stability. The end cap 29 has multiple sets of water inlet holes 37, and a limiting ring 28 is provided at the opening end of the groove 35. Through the design of the multi-hole diversion and limiting structure, the water pressure distribution can be balanced, improving impact resistance.

[0029] like Figure 2 , 4As shown, a motor 13 is housed within the pump body 11, and an impeller 14 is housed within the volute 12. The impeller 14 is connected to the output shaft of the motor 13. This direct drive configuration between the motor 13 and the impeller 14 enhances power transmission efficiency and improves drainage performance. The control module 24 is electrically connected to the backwash pump 18 and the motor 13. Through multi-device collaborative control, start-up, shutdown, and mode switching can be achieved, improving system integration.

[0030] The specific usage and function of this embodiment are as follows:

[0031] In practical use, the drainage pump device with water level control function operates and functions as follows: First, the device is installed in the area where drainage is needed. After the power is turned on, the motor 13 drives the impeller 14 inside the volute 12 to rotate, generating suction, and water flows in from the inlet pipe 15. The filter 17 inside the inlet pipe 15 starts working, purifying the water quality and reducing the wear of impurities on the pump body 11. When the water level sensor 26 detects that the water level has reached the preset start water level, the water level control module 25 starts the motor 13 through the control module 24, and the drainage work officially begins. The water flows through the volute 12 and is discharged from the drain pipe 16. If backflushing is required, the control module 24 will control the two sets of first control valves 19 to close and start the backflushing pump 18 at the same time. At this time, the second control valve 22 opens, the suction port 21 draws in the surrounding water, and a reverse water flow is formed between the inlet pipe 15 and the drain pipe 16. The water flow generated by the backflushing pump 18 washes away the impurities attached to the filter 17 and the inner wall of the pipe, realizing the self-cleaning function and ensuring smooth drainage. The control module 24 inside the pump cover 23 processes signals from the water level sensor 26, pressure sensor 34, etc., and controls the operation of each component.

[0032] The end cap 29 on the water inlet pipe 15 cooperates with the connector. When the water level rises, the suspended ball 33 moves the end cap 29 within the sleeve 32 as the water level rises. The pressure sensor 34 at the top of the sleeve 32 detects the pressure change and transmits it to the control module 24. The control module 24 then adjusts the opening and closing of the motor 13 to prevent it from running dry. The sliding groove 35 on the end cap 29 cooperates with the slider 36 to guide the sliding of the end cap 29. Multiple sets of water inlet holes 37 increase the water intake efficiency, and the limiting ring 28 prevents the slider 36 from falling out.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
