Critical-free automatic control system for water feeding of water tank

Abstract

The invention discloses a critical-free automatic control system for water feeding of a water tank. A stirring block comprises a first concave opening part of a concave structure, a stirring fork is hinged to a rack, a first end of the stirring fork is located in the first concave opening part of the stirring block, a second end of the stirring fork is provided with a second concave opening part of a concave structure, a magnet is arranged below the second end of the stirring fork, a triggering block is hinged to the rack, and a first end of the triggering block is located in the second concave opening part of the stirring fork; a slide rod is vertically and slidably installed in a guide mechanism, the lower end of the slide rod is fixed to a floating object, the floating object floats onthe water surface in the water tank, the upper end of the slide rod is connected with the stirring block, and the slide rod slides up and down to drive the stirring block to move; a water pump is connected between a positive electrode and a negative electrode of a circuit, a water outlet of the water pump leads to the water tank, the triggering block is a conductor and is connected with the negative electrode of the circuit, the stirring block moves to drive the stirring fork to swing, the stirring fork stirs the triggering block, and the triggering block swings the second end of the stirringfork to be in contact with the positive electrode of the circuit. The system has the advantage of achieving more accurate and reliable control by crossing critical points.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a non-critical automatic control system 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...
