Waterproof cable tension sensor and inspection platform

Abstract

The present invention provides a waterproof cable tension sensor and an inspection platform. The sensor comprises a fixed seat, a sliding rail mechanism, a cable tension acquisition mechanism and a sensing mechanism. The upper part of the fixed seat is fixed with the sliding rail mechanism; the sliding rail mechanism comprises a slider; the cable tension acquisition mechanism acquires the cable tension and is fixedly connected with the slider; the sliding rail mechanism has a displacement that causes the slider to move in the direction of cable tension; a magnet is arranged at the bottom of the slider; and the movement distance of the slider is proportional to the cable tension. The bottom of the fixed seat is fixed with a sensing structure; the sensing mechanism acquires the position of the slider by obtaining the magnetic field of the magnet; and the cable tension is output according to the position of the slider. In the present invention, a device system is designed. The invention is based on the device and an encoder chip; the magnet is fixed with the slider; and the position sensing in the underwater lateral movement scene is realized.

Description

technical field [0001] The invention relates to the field of sensors, and more particularly, to a waterproof cable tension sensor and an inspection platform. Background technique [0002] For the amphibious inspection platform, signals, etc. need to be guided to the water surface through the buoy system and then communicate with the roadbed. Obtaining the tension of the cable plays an indispensable role. The waterproof tension sensor currently used in the market is mainly based on the waterproof Hall sensor, which has the advantages of high precision and convenient assembly. However, the Hall sensor mainly measures the magnetic change and converts the distance or angle of the magnetic object. In the scene of lateral movement in the water, the error is too large due to the influence of the intermediate medium or the obstruction, and the sensing distance is short. In addition, the Hall sensor also has the disadvantage of high price. Most importantly, there is no waterproof s...

AI Technical Summary

Problems solved by technology

However, the Hall sensor mainly measures the magnetic change and converts the distance or angle of the magnetic object. In the scene of lateral movement in the water, it is easily affected by the intermediate medium or the obstruction, resulting in excessive error and short sensing distance.

In addition, the Hall sensor also has disadvantages such as high price

Most importantly, there is no waterproof sensor that can directly measure the wire tension in the existing market

In addition, the body is equipped with various high-current working devices, which generate various magnetic fields, which easily affect the measurement accuracy of the Hall sensor.
