Problems solved by technology

[0002] The submersible pump is one of the most commonly used equipment for dewatering in foundation pits and other deep excavation projects. During its use, the following situations are often encountered: when the water level is below the minimum water level, if the pump continues to pump water, the pump body will be damaged. It will eventually cause the pump to burn due to idling heat, which will endanger the safety of the foundation pit construction. In order to avoid burning the pump, the project is often equipped with special caregivers. Once the demand for the pump is large, the workers will monitor multiple pumps at the same time. If you can’t do what you want, you will undoubtedly need to increase the amount of labor and improve the strength of the operation. Therefore, it is particularly important to design a switch that can automatically control the switch.

Embodiment 1

[0023] Such as figure 1 As shown, the submersible pump automatic control switchgear provided in this embodiment includes a power supply 1, a water pump motor 2 and a control mechanism, the power supply 1 is connected to the water pump motor 2, and the control mechanism includes a water level control switch 3, a control mechanism The switch 4 and the electromagnetic control driving device 6, the control switch 4 is connected in series between the power supply 1 and the water pump motor 2, and the lower water level control switch 3 and the coil of the electromagnetic control driving device 6 are connected in series between the positive and negative poles of the power supply 1 .

[0024] When working, use the floating ball to drive the lower water level control switch 3 to work. When only the lower water level control switch 3 is turned on, the water pump does not work. At the same time, when the control switch 4 is turned on, the water pump starts to work. The water pump doesn'...

Embodiment 2

[0026] Such as figure 2 As shown, the general structure of the submersible pump automatic control switch device provided by this embodiment is the same as that of Embodiment 1, the difference is that the control switch 4 is used as the upper water level control switch 9, and the upper water level control switch 9 is connected to the upper water level control switch 9. Electromagnetic control driving device 6 cooperates to lock.

[0027] In this embodiment, the floating ball controlling the upper water level control switch 9 and the lower water level control switch 3 is the same floating ball during specific operation, and the lower water level control switch 3 is a normally closed switch, and the upper water level control switch 9 is a normally open switch. The float is set between the two switches and is in contact with the lower water level control switch 3. At this time, the lower water level control switch 3 is in a disconnected state, and the water pump does not work. As...

Embodiment 3

[0029] Such as image 3 As shown, the general structure of the submersible pump automatic control switch device provided by this embodiment is the same as that of Embodiment 2, the difference is that the circuit where the lower water level control switch 3 is connected in series with the coil of the electromagnetic control drive device 6 is also electrically connected There is a first control power supply 7 .

Abstract

The invention discloses a submersible pump automatic control switch device for water pump switch control, comprising a power supply, a water pump motor and a control mechanism, the power supply is connected to the water pump motor, and the control mechanism includes a water level control switch, a control switch and the electromagnetic control driving device, the control switch is connected in series between the power supply and the water pump motor, and the lower water level control switch and the coil of the electromagnetic control driving device are connected in series between the positive and negative poles of the power supply. The submersible pump automatic control switch device obtained in the present invention uses the water level change to control the switch to close, thereby realizing automatic control of the water pump to start or stop, so that the overall structure is simple, and the function of automatic control is realized in a real sense.

Description

technical field [0001] The invention relates to a control device for a water pump, in particular to an automatic control switch device for a submersible pump. Background technique [0002] The submersible pump is one of the most commonly used equipment for dewatering in foundation pits and other deep excavation projects. During its use, the following situations are often encountered: when the water level is below the minimum water level, if the pump continues to pump water, the pump body will be damaged. It will eventually cause the pump to burn due to idling heat, which will endanger the safety of the foundation pit construction. In order to avoid burning the pump, the project is often equipped with special caregivers. Once the demand for the pump is large, the workers will monitor multiple pumps at the same time. If the power is not enough, it will undoubtedly need to increase the amount of manpower and improve the strength of the operation. Therefore, it is particularly i...
