The invention discloses a water tank non-critical automatic control switch. The shift block includes a first notch, the shift fork is hinged on the frame, the first end of the shift fork is located in the first notch of the shift block, and the second of the shift fork The two ends are provided with a second notch, a magnet is provided above the second end of the shift fork, the trigger block is hinged on the frame, the first end of the trigger block is located in the second notch of the shift fork, the top of the shift block is connected to the first end of the connecting wire, The bottom of the shift block is connected to the end of the connecting wire, the floating object is connected to the middle of the connecting wire, and the floating object floats on the water surface in the water tank; the water pump is connected between the positive pole of the circuit and the negative pole of the circuit, the water pump outlet leads to the water tank, and the touch block is a conductor And it is connected with the negative pole of the circuit, the movement of the shifting block drives the shifting fork to swing, and the shifting fork moves the trigger block. When the trigger block swings, the second end of the trigger block can contact with the positive pole of the circuit, and the water pump is powered to work and inject water into the water tank. The advantages of the invention are: beyond the critical point, the control is more accurate and reliable.
Description
technical field [0001] The invention relates to the field of automatic control, in particular to a non-critical automatic control switch for filling a water tank. Background technique [0002] In many fields of modern science and technology, automatic control technology plays an increasingly important role. Automatic control refers to the use of external equipment or devices to make a certain working state or parameter of a machine, equipment or production process automatically operate according to a predetermined law without direct participation of humans. The operator is freed from tedious labor to engage in other work, which greatly saves human resources and improves production efficiency. The automatic water supply of water tanks, water towers, etc. is an important application of automatic control technology in the fields of life and industrial production. However, in the prior art, the automatic water supply control switch of the water tank has poor reliability and has...
