A New Float Type Liquid Level Automatic Control Device

Abstract

A new type of float type liquid level automatic control device, including float, long arm, sliding cylinder, sliding rod, toggle lever, toggle lever cavity, power switch, etc. The utility model is characterized in that one end of the long arm is connected with a float, and one end is connected with a sliding rod; the sliding rod is provided with a sliding rod; and the sliding cylinder is provided with a sliding path corresponding to the sliding rod, so that the sliding rod can slide on the sliding cylinder. It slides vertically inside; the sliding rod is provided with a toggle lever for toggling the toggle lever; the toggle lever is provided with a vertical toggle block for toggle the power switch; the power switch is connected with the electric device for supplying water to the water tank. There is a lever sliding hole on one side of the sliding cylinder, so that the lever can be moved up and down along the lever sliding hole during the operation of the device, so as to drive the lever to move up and down; The direction dial can drive the opening and closing of the power switch, so as to achieve the purpose of automatic liquid control. The invention has the advantages of simple structure, low price, good force transmission effect, good control effect and the like; it can be widely used for water storage and liquid control in rural areas, cities and the like.

Description

technical field [0001] The invention relates to a liquid level control device, in particular to a float type liquid level automatic control device. Background technique [0002] Since the beginning of the 21st century, the rapid development of the world economy has caused human beings to overdraw the earth's resources in advance. Water resources have become the most scarce natural resources today. Water conservation and rational use of water are now the top priority for human survival. [0003] Existing water storage facilities are generally equipped with water level control systems, usually manual and automatic. In the automatic water level control system, a simple mechanical device such as a water toilet tank, which manually lowers the water level and then makes the float drive the valve piston to inject water; it is not only easy to damage during use, but also not suitable for large water storage facilities The water level is automatically controlled. Complicated water ...

AI Technical Summary

Problems solved by technology

Although the device is simple in structure and small in size and solves some technical problems, it also has defects: one is that the hollow float is generally made of plastic with air inside, and its specific gravity is smaller than that of water. Although the buoyancy is very good, it can control the water surface The gravity of the float is obviously insufficient when descending, so the two-way force transmission of the force transmission mechanism is inconsistent and the force transmission of the gear is unstable. A certain arc, if the two-way force transmission is inconsistent and the gear transmission force is unstable, it will easily cause the operation of the lever to fail; the third is that the device does not consider the control of the liquid level other than the water outlet, so the application range has certain limitations

Although the structure of this device is simpler than the previous one, the two-way force transmission is consistent and the speed of the float rises and falls is stable, and it is also applicable to the level control of other liquids including water. The transmission mode of the pulley and the transmission belt, one section of the transmission belt is a structure with a certain deflection such as a steel wire, and the other section is a belt, and the belt is provided with two shifting blocks; in such a structure, the connection between the steel wire and the belt is easy to break , the transmission belt is easy to fall off, resulting in failure of force transmission; the shift block on the belt is not easy to fix, and it is very easy to fall off, resulting in control failure
