Balancing device for floating content gauge

Abstract

A balancer in wheel shaft structure comprises DC motor erected in motor seat, balance wheel and wire winding wheel on DC motor. A group of transducer is set on corresponding position of balance wheel outer edge to motor seat, wire winding wheel is shrunk-on external end portion of motor shaft at outer side of balance wheel.

Description

technical field [0001] The invention relates to a float type water level gauge, in particular to a balance device for the float type water level gauge. Background technique [0002] Float-type water level gauges are widely used in water level measurement of reservoirs, dams, rivers, etc. Vertical well measurement methods are generally used: build a vertical parallel, and use floats and counterweights to measure water levels. The construction cost of this method is relatively high. High; it is relatively simple to use the slope logging method of the float type water level gauge, but a counterweight lift shaft is also needed in places such as reservoir dams, and the cost of building the lift shaft is also very high. Chinese patent 01276330.6 discloses a new structure float type water level gauge, the balance box is designed as a slide bar structure, including balance reminder, water level sensing pulley, guide pulley, guide rail, sliding cross bar, wire wheel, reversible motor...

Problems solved by technology

Chinese patent 01276330.6 discloses a new structure float type water level gauge, the balance box is designed as a slide bar structure, including balance reminder, water level sensing pulley, guide pulley, guide rail, sliding cross bar, wire wheel, reversible motor And the switch circuit, the switch circuit is composed of a relay switch connected in parallel with a power switch in series, and the counterweight mounted on the sliding bar moves up and down to contact with the switch, thereby controlling the rotation of the motor. This structure is relatively simple, but in practice During the application process, the guide pulley is easily stuck with the guide rail, which leads to the failure of the balance device, and the maintenance frequency is very high, which brings great inconvenience to the actual application.
