Abstract

The invention relates to a tuning fork liquid level switch convenient to maintain and overhaul. The tuning fork liquid level switch comprises a box body, a rotating arm, a vibration fork, a base and a motor. A rotating shaft is installed on the surface of one side of the box body in a penetrating mode, the motor is arranged in the box body, the rotating arm is rotatably installed on one side of the motor, the vibration fork is arranged on one side of the rotating arm, and the base is arranged on one side of the vibration fork. A spring is arranged between the base and the vibration fork, a guide rail is arranged in the base, the vibration fork is movably inserted into the guide rail, a limiting key is arranged on one side of the base, and a limiting groove is formed in the inner wall of the box body. The motor is started and rotates to drive the rotating arm to rotate, so that the vibration fork vibrates back and forth in the guide rail at a fixed frequency, when the liquid level reaches the vibration fork part, the vibration frequency is changed, a vibration sensor senses a signal and transmits the signal to a control end, a liquid level control effect is achieved, and the problem that part of tuning fork liquid level switches are inconvenient to disassemble and overhaul quickly is solved.

Description

technical field [0001] The invention relates to the technical field of liquid level detection, in particular to a tuning fork liquid level switch which is convenient for maintenance and repair. Background technique [0002] The working principle of the vibrating fork switch is to use a pair of vibrating forks with a natural vibration frequency. When the water surface is quiet and submerged in the vibrating fork, the vibration frequency changes, and the sensor transmits the signal of this frequency change to the controller for switch control. [0003] After a massive search, it was found that the prior art publication number is CN204330084U, which discloses a vibrating fork liquid level switch device, which includes a vibrating fork liquid level switch, a T-shaped tee and a drain valve, and is characterized in that the T-shaped tee passes through The wall flange is connected with the container, the vibrating fork liquid level switch is vertically installed on the top of the T...
