Description
Technical field
The present invention relates to the opertaing device of water quality detecting device underwater penetration, is the underwater penetration sensor of water quality detecting device specifically.
Background technology
Water quality detection in the prior art adopts equipment such as bottle gouard moved by hands or electric block can only lift by crane the lifting water quality detecting device, can't controlledly water quality detecting device be hung in to specify the depth of water to carry out water quality detection.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, a kind of underwater penetration sensor of water quality detecting device is provided, arrive the water surface or water-bed position in the hope of accurately recording water quality detecting device, and the degree of depth of entry, so that the detection that water quality detecting device can be from the water surface to various water-quality guideline such as the water-bed water temperature that carry out the different depth of waters exactly, conductivity, transparencies.
Technical solution problem of the present invention adopts following technical scheme:
The design feature of underwater penetration sensor is in the water quality detecting device of the present invention: fixing electric block on suspension bracket, in the bulging side of cucurbit rope rope drum pitch of the laps is set and counts sensor, the hook of rope drum wire rope connects water quality detecting device, is respectively arranged with water level sensor and water-bed sensor on water quality detecting device.
The design feature of underwater penetration sensor also is in the water quality detecting device of the present invention:
Described rope drum pitch of the laps is counted being set to of sensor: the side setting at cucurbit rope drum is roused the rope drum end plate that rotates with the cucurbit rope, on rope drum end plate outer face, be positioned at the rope drum end plate same circumferential position on each revolution sensing magnet piece evenly is set, with the rope of described rope drum end plate opposite position drum reducer casing in a machine box is set, there are two revolution sensing Hall elements to be provided with at interval in the machine box, described two revolution sensing Hall elements and described revolution sensing magnet piece are on the same circumferential position, constitute electromagnetic induction device with described revolution sensing Hall element and revolution sensing magnet piece.
