Description

Automatic water supply device

technical field

The utility model relates to a water supply device, in particular to a device for automatically controlling water supply.

Background technique

With the improvement of rural living standards, more and more farmers are digging wells by themselves. Pumping water instead of manual water pumping, but manual control of pumping is required, which is very inconvenient, often overflowing, and wastes electricity and energy. source of water.

Contents of the invention

The purpose of this utility model is to provide an automatic water supply device. When the water level is low, the power is automatically turned on to start the motor to supply water, and when the water level reaches a certain height, the power is automatically turned off to stop the water supply.

The utility model is composed of a water tank, a water pump, and a control switch. The water tank has an inlet pipe and an outlet pipe connected to the water pump. The control switch is connected by a contact switch on the top of the water tank, and the bottom of the water tank is connected with the contact switch through a connecting rod. The upper float of the lower float and the upper part of the water tank is connected with the contact switch through the connecting rod and is responsible for disconnecting the power supply.

The upper float and the lower float of the control switch can be slidably fixed on a vertical slide bar in the water tank.

The water tank also has an overflow pipe leading from the upper part of the water tank, and the water outlet pipe includes a non-drinking water pipe leading from the bottom of the water tank and a drinking water pipe leading from the middle and lower part of the water tank.

The water pump can be a centrifugal pump or a submersible pump, preferably a two-phase electric micro-water pump.

The utility model has the advantages of: 1. The control switch completely adopts a mechanical contact structure, the power is disconnected by the upper float, and the power is connected by the lower float. The structure is simple, the cost is low, the operation is stable and reliable, and the maintenance is convenient. 2. An overflow pipe is set on the water tank. In case the control switch is out of control, the water can flow from the pipe to the appropriate position. 3. The non-drinking water pipe is at the bottom of the water tank to remove sediment, and the drinking water pipe is at the middle and lower part of the water tank to ensure clean water. 4. Using two electric micro pumps can save electric energy.

Detailed ways

As shown in Figure 1, the utility model is composed of a water tank 10, a water pump 1, a control switch 7, etc. The water tank 10 has an inlet pipe 6 connected to the water pump 1, an overflow pipe 11 is drawn from the top of the water tank 10, and a non-conductive pipe 11 is drawn from the bottom of the water tank 10. The drinking water pipe 13 and the drinking water pipe 12 drawn from the lower part of the water tank 10; the control switch 7 is composed of a contact switch 8 on the top of the water tank, a lower float 2, an upper float 5 and a slide bar 4, wherein the lower float 2 and the upper float 5 is slid and fixed on the vertical slide bar 4 in the water tank. The lower float 2 is connected to the contact switch 8 at the bottom of the water tank 10 through the connecting rod 3 and is responsible for turning on the power supply. The point switch 8 is connected to be responsible for disconnecting the power supply; the water pump 1 adopts a low-power submersible pump with two power supplies.
