Self-adjustable retracting and releasing device for anchor cable

Abstract

The invention relates to a self-adjustable retracting and releasing device for an anchor cable, which belongs to the technical field of ocean monitoring. The self-adjustable retracting and releasing device comprises a volute spiral spring assembly, a lever mechanism, a pressing mechanism, a clutch mechanism, a winch assembly and a support seat. The self-adjustable retracting and releasing device can achieve the functions of automatically retracting and releasing a moored water floating object anchor chain within a certain length range by using the characteristic that the plane volute spiral spring assembly can store and release certain torque energy; when the water resistance borne by the floating objects changes because floating objects floating in the water are influenced from the outside environment and the tension borne by the moored anchor chain correspondingly changes; when the tension borne by the moored anchor chain is greater than a fixed value, the self-adjustable retracting and releasing device starts to release the anchor chain; and when the tension borne by the moored anchor chain is smaller than the certain value, the self-adjustable retracting and releasing device automatically retracts the moored chain.

Description

technical field [0001] The invention relates to an anchor cable retracting and releasing device, in particular to a self-adjusting anchor cable retracting and releasing device, which belongs to the technical field of marine monitoring devices. Background technique [0002] In marine engineering and marine hydrometeorological investigation and monitoring applications, marine detection equipment is moored within a certain range on the sea surface, floats on the sea surface with waves, and timely monitors marine hydrometeorological conditions within a certain sea area in order to obtain accurate information. Hydrometeorological conditions. Currently generally used mooring methods: one is fixed-length mooring, that is, according to the depth under the water surface, a certain length of mooring chain is released to make the floating body loaded with the monitor float on the sea surface. In case of weather, the floating body carrying the instrument may be buried in the water, aff...

Problems solved by technology

Currently generally used mooring methods: one is fixed-length mooring, that is, according to the depth under the water surface, a certain length of mooring chain is released to make the floating body loaded with the monitor float on the sea surface. In case of weather, the floating body carrying the instrument may be buried in the water, affecting the real-time detection of hydrometeorological data and interruption of communication with the shore station center; The equipment is complicated, and equipment such as power supply, motor and pressure sensor need to be configured, the work reliability is low, and regular maintenance is required
