[0019] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0020] like Figure 1 As shown, the pumping device includes a water pump 10 and a water level monitoring mechanism. The water pump 10 can be placed in a water collection well to pump out the water in the water collection well. The specific type of the water pump 10 can be selected according to actual needs, and this application does not make specific restrictions. The water level monitoring mechanism can monitor the water level in the water collection well and control the opening and closing of the water pump 10 according to the water level in the water collection well.

[0021] Specifically, the water level monitoring mechanism includes a cylinder 20 , a reset switch 30 and a floating assembly 40 .

[0022] The cylinder 20 may be a cylindrical cylinder 20, and the cylinder 20 includes a bottom plate 21, a peripheral side plate 22 and a top plate 23, wherein the peripheral side plate 22 is located between the bottom plate 21 and the top plate 23, and the peripheral side plate 22 extends along the peripheral side of the bottom plate 21 and the top plate 23, and the peripheral side plate 22 is connected to the bottom plate 21 and the top plate 23 to form a vertically extending accommodating cavity 24 surrounded by the bottom plate 21 and the top plate 23, and a plurality of connecting holes 25 penetrating the peripheral side plate 22 and communicating with the accommodating cavity 24 are provided on the outer peripheral side surface of the peripheral side plate 22; the reset switch 30 is arranged Installed on the inner side of the top plate 23, the reset switch 30 is electrically connected to the water pump 10. When the reset switch 30 is pressed, the water pump 10 starts. When the reset switch 30 is released and reset, the water pump 10 is turned off. The reset switch 30 is also called a moment switch, which can control the start and stop of the water pump 10. The specific working principle of the reset switch 30 has long been disclosed in the relevant technology and will not be elaborated in this application. The floating component 40 is located in the accommodating cavity 24. The floating component 40 can float under the buoyancy of water. The floating component 40 is used to press the reset switch 30 when floating to a preset height.

[0023] It can be understood that when the water pumping device is used, the water pump 10 and the cylinder 20 can be placed in the water collection well, with the bottom plate 21 of the cylinder 20 facing downward and the top plate 23 facing upward. The water in the water collection well can enter the accommodating chamber 24 through the connecting hole 25, so that the water level in the accommodating chamber 24 is the same as the water level in the water collection well. When the water enters the accommodating chamber 24, the floating component 40 floats on the water surface under the buoyancy of the water and rises and falls with the rise and fall of the water level. When the water rises to the starting level, the floating component 40 floats to a preset height, and the floating component 4 0 will press the reset switch 30, so that the water pump 10 starts and the water in the sump is discharged in time. The specific height of the starting liquid level can be selected according to actual needs; when the water level in the sump is lowered to the point where the floating assembly 40 is separated from the reset switch 30, the reset switch 30 is reset under the action of its own elastic force, so that the water pump 10 is shut down, thereby preventing the water level in the sump from lowering and causing the water pump 10 to be exposed to the water surface and idling for a long time, resulting in overheating and burning. The water pump 10 can be started and closed without the need for on-site personnel to operate, making the start and close of the water pump 10 more convenient and timely.

[0024] In addition, the cylinder 20 can provide protection for the reset switch 30 and the floating component 40, and the connecting hole 25 on the cylinder 20 can play a filtering role to prevent large particles of impurities and impurities such as plastic bags from entering the accommodating chamber 24 and causing blockage of the accommodating chamber 24. The number and specific aperture of the connecting holes 25 can be selected according to actual needs; in addition, the reset switch 30 is located on the top plate 23 and has a relatively high height. For example, the cylinder 20 can be 4 meters long, and the placement height of the reset switch 30 is close to 4 meters, which can prevent the reset switch 30 from being immersed in water and causing damage to the reset switch 30. The length of the cylinder 20 can be selected according to actual needs so that the top plate 23 and the reset switch 30 installed on the top plate 23 have sufficient height.

[0025] Specifically, the floating assembly 40 includes a floating ball 41 and a pressure rod 42. The floating ball 41 can float under the buoyancy of water; the pressure rod 42 is located above the floating ball 41 and is fixedly connected to the floating ball 41. The pressure rod 42 is used to press the reset switch 30 when the floating ball 41 floats to the preset height. It can be understood that the floating ball 41 is a spherical structure made of a material with large buoyancy such as foam plastic. The floating ball 41 can float on the water surface under the buoyancy of the water, and drive the pressure rod 42 to rise and fall with the rise and fall of the water level. When the floating ball 41 floats to the preset height, the pressure rod 42 rises to contact the reset switch 30 and presses the reset switch 30, thereby starting the water pump 10. Among them, the pressure rod 42 can be integrally formed with the floating ball 41.

[0026] Furthermore, the peripheral side plate 22 includes a first portion 221 and a second portion 222 , the first portion 221 is connected to the bottom plate 21 , and the second portion 222 is located above the first portion 221 and connected to the first portion 221 and the top plate 23 .

[0027] The accommodating cavity 24 includes a first cavity 241 located in the first part 221 and a second cavity 242 located in the second part 222. The diameter of the first cavity 241 is larger than the diameter of the second cavity 242. The floating ball 41 is located in the first cavity 241, and the top end of the pressing rod 42 extends into the second cavity 242. It can be understood that the cavity diameter of the first cavity 241 is larger, which can more conveniently accommodate the floating ball 41 with a larger volume, so that the floating ball 41 can have a greater buoyancy, thereby ensuring that the floating assembly 40 can rise and fall with the rise and fall of the water level; the cavity diameter of the second cavity 242 is smaller, which can provide a good guiding effect for the pressing rod 42 in vertical sliding, and can prevent the pressing rod 42 from shaking left and right, so that the pressing rod 42 can smoothly and accurately press the reset switch 30.

[0028] Furthermore, the outer peripheral surface of the pressure rod 42 contacts the inner wall surface of the second cavity 242, and the pressure rod 42 can slide vertically along the second cavity 242, which can reduce the gap between the pressure rod 42 and the inner wall surface of the second cavity 242, so that the pressure rod 42 can smoothly and accurately press the reset switch 30, and at the same time prevent the water in the first cavity 241 from flowing to the reset switch 30.

[0029] In one embodiment, the top surface of the pressing rod 42 is a spherical arc surface, so that the pressing rod 42 can slide vertically along the second cavity 242 more smoothly, thereby preventing the pressing rod 42 from getting stuck in the second cavity 242 .

[0030] In one embodiment, the inner wall surface of the second cavity 242 is a polished surface, which can enhance the smoothness of the inner wall surface of the second cavity 242 and make the pressing rod 42 slide more smoothly.

[0031] In some embodiments of the present application, the diameter of the first cavity 241 is larger than the ball diameter of the float 41, so that there can be a gap between the float 41 and the inner wall surface of the first cavity 241, thereby making the rise and fall of the float 41 smoother, and at the same time preventing the float 41 from being scratched against the inner wall surface of the first cavity 241 and causing damage to the float 41.

[0032] Furthermore, bristles 43 are provided on the outer peripheral side of the float 41, and the bristles 43 are in contact with the inner wall surface of the first cavity 241, so that when the float 41 floats up and down, the bristles 43 can brush the connecting hole 25 to prevent dirt such as mud and sand from clogging the connecting hole 25. The bristles 43 can preferably be hard bristles 43 to prevent soft bristles 43 from being entangled with the connecting hole 25.

[0033] In one embodiment, the connecting hole 25 is disposed in the first part 221 . The connecting hole 25 is disposed only in the first part 221 , but not in the second part 222 . This can prevent rainwater from entering the second cavity 242 through the connecting hole 25 and contacting the reset switch 30 .

[0034] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
