Abstract

The invention provides an underwater depthkeeping automatic retracting and launching device for a detecting instrument. A cable winds on a roller; the end part of the cable bypasses a rolling wheel and is connected with the detecting instrument; when a first stepping motor drives the rolling wheel to rotate along the first direction, a first one-way bearing and a second one-way bearing are locked,a third one-way bearing is released, and the roller rotates around the third one-way bearing so as to release the detecting instrument; when a second stepping motor drives the roller to rotate alongthe second direction, the first one-way bearing and the second one-way bearing are released, the third one-way bearing is locked, and the rolling wheel rotates around the first one-way bearing so as to retract the detecting instrument; and only one circle of cable exists on the rolling wheel, and winding and unwinding are carried out by adopting the different stepping motors, so that during unwinding, the launching depth of the detecting instrument can be set through fixing the rotation circle numbers of the first stepping motor, and accurate launching in different depths underwater is realized.

Description

technical field [0001] The invention relates to the technical field of underwater detection, in particular to an automatic retractable device for underwater depth determination of a detector. Background technique [0002] In recent years, with the rapid development of industrial production, while people's lives have been improved, environmental pollution has become one of the major problems facing modern society, and water quality testing is particularly important. When testing certain water quality indicators, such as water hardness testing, it is often necessary to perform depth-fixed detection of water quality at different depths, so it is often desirable that the detection device has the function of constant-depth delivery. However, the common retracting devices currently on the market are mainly to wind the cable on the reel, and then realize the retraction through the motor drive. The cable on the reel is relatively thick, so the number of turns is different and the d...
