Description

Technical Field

[0001] This utility model relates to the field of control device technology, and in particular to an automatic start-stop control device for a water pump. Background Technology

[0002] A submersible pump is a mechanical device used to transport liquids, primarily for pumping water or other liquids from a lower elevation to a higher elevation, or from one place to another. It is typically driven by an electric motor, using the centrifugal force generated by the rotation of an impeller to draw in and discharge liquid. A key feature of submersible pumps is that the entire unit (including the motor) can be immersed in the liquid, making them widely used in agricultural irrigation, industrial drainage, urban water supply, and wastewater treatment.

[0003] In the existing technology, the float submersible pump controls the start and stop of the water pump by using a float that floats outside the submersible pump and is connected to a pipe. This type of float control requires a large amount of space to move around, and the narrow space in the operating environment can cause the water pump to fail to operate normally. Utility Model Content

[0004] The purpose of this invention is to solve the shortcomings of existing technologies, such as the need for a large operating space for water pumps to start and stop, and the inability of water pumps to operate normally due to narrow operating environments.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic start-stop control device for a water pump, comprising: a sealed shell, a current controller fixedly installed inside the sealed shell by bolts, a sleeve fixedly installed on one side of the sealed shell, a float ball slidably connected inside the sleeve, air vent shells fixedly installed at the top and bottom of the sleeve, a sensor fixedly installed inside the sealed shell, and a signal line electrically connected to one end of the sensor.

[0006] In a preferred embodiment, a mounting bracket is fixedly installed at the bottom of the sealing shell, and an external interface is electrically connected to the current controller.

[0007] In a preferred embodiment, one side of the sleeve is connected to the sensor via a pipe.

[0008] In a preferred embodiment, the external interface is electrically connected to a power cord.

[0009] In a preferred embodiment, the signal line is electrically connected to the current controller.

[0010] In a preferred embodiment, the external interface on the current controller is electrically connected to the control terminal of the water pump.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] This utility model

[0013] The mounting bracket is fixed to the pump. The current controller controls the flow of current. When the device is placed in the well and there is water, the float will float in the casing. When it floats to the sensor, the sensor receives a signal and transmits the signal to the current controller via a signal line. The current controller will then be energized, and the external water pump will start pumping water. When the water level drops, the float will descend, and the sensor will stop energizing. The controller will then cut off the power, and the water pump will stop working. The main function is to control the start and stop of the water pump. The vent shell is used for venting and absorbing air and to prevent mud and sand from clogging the casing. It can control the water pump in various environments and working conditions, automatically starting and stopping when there is a lack of water. The compact design allows it to be fixed to the water pump and used in confined spaces.

[0014] When the float reaches the sensing area, it controls the water pump to start with a delay, thus preventing the motor from burning out due to frequent starts. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example

[0022] like Figure 1-3As shown, this utility model provides a technical solution: an automatic start / stop control device for a water pump, comprising: a sealed shell 9, a current controller 1 fixedly installed inside the sealed shell 9 by bolts, a sleeve 4 fixedly installed on one side of the sealed shell 9, a float 3 slidably connected inside the sleeve 4, vent shells 2 fixedly installed at the top and bottom of the sleeve 4, a sensor 5 fixedly installed inside the sealed shell 9, a signal line 8 electrically connected to one end of the sensor 5, a fixing bracket 6 fixedly installed at the bottom of the sealed shell 9, an external interface 7 electrically connected to the current controller 1, and a sleeve 4 on one side. The device is connected to sensor 5 via a pipe. External interface 7 is electrically connected to a power cord. Signal line 8 is electrically connected to current controller 1. External interface 7 on current controller 1 is electrically connected to the control terminal of the water pump. As the water level drops, float 3 moves away from the sensing area, and the water pump stops immediately. When float 3 reaches the sensing area, it controls the water pump to start with a delay, avoiding frequent starts that could burn out the water pump motor. This can save more than 50% of electricity. The device is compact and can be fixed on the water pump, allowing it to be used in confined spaces. The sealed shell 9 is sealed with glue to protect the internal circuit components of the controller from water damage.

[0023] Working principle:

[0024] like Figure 1-3 As shown, the mounting bracket 6 is fixed together with the pump. The current controller 1 is used to control the flow of current. When the device is placed in the well, and there is water in the well, the float 3 will float in the casing 4 through the water. When it floats to the sensor 5, the sensor 5 will receive a signal and then transmit the signal to the current controller 1 through the signal line 8. The current controller 1 will then be energized by the received signal. At this time, the external water pump will start to work and pump water. After the water level drops, the float 3 will drop. At this time, the sensor 5 will stop the energizing signal. The controller will cut off the power, and the water pump will stop working. This device is mainly used to control the start and stop of the water pump. The air vent shell 2 is used for venting and energizing and to prevent mud and sand from being unable to be discharged, which would cause blockage in the casing 4. It can control the water pump to start and stop automatically due to water shortage in various environments and working conditions.

[0025] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
