Description

Technical Field

[0001] This invention relates to the field of hydrological monitoring, and in particular to an automatic detachment device for lead fish used to prevent floating objects. Background Technology

[0002] Hydrological monitoring is the collection of data related to water bodies, focusing on various hydrological elements of rivers, lakes, and seas. River and lake hydrological elements include water depth, water level, flow direction, flow velocity, discharge, water temperature, ice conditions, specific gravity, sediment content, precipitation, evaporation, water color, transparency, and the chemical composition of water. Marine hydrological elements include tides, currents, waves, ocean currents, seawater temperature, salinity, sea surface temperature, air pressure, wind direction, wind speed, and plankton. Hydrological observation stations are typically established at specific locations or sections within rivers, lakes, and seas to conduct long-term, uninterrupted hydrological observations. After processing and analysis, the various hydrological observation data not only form the basis for hydrological forecasting but also serve as crucial data for studying seabed, riverbed, and bank changes, ocean currents, runoff patterns, and for designing and calculating hydraulic and coastal engineering projects, as well as compiling navigation guides. Lead weights are used in hydrological observation. Lead weights for hydrological cableway surveys are hydrological measuring instruments made of lead or a lead-iron mixture, possessing a certain weight and elongation ratio, and a streamlined shape. The structure of the lead weight is based on a streamlined body, with a suspension mechanism and current meter suspension rod mounted on its back, along with the longitudinal and transverse tails and signal source, forming the complete lead weight unit. Currently, lead weights are generally suspended in the water by steel cables for monitoring. During use, when tethered by floating objects such as aquatic plants, the lead weight cannot automatically detach from the steel cable, and the cable pull can easily damage the cableway support or even cause it to be washed away.

At this time, the locking post will be compressed into the second mounting groove. After the locking post is compressed into the second mounting groove, the connecting leg will disengage, thereby realizing the automatic disengagement of the lead weight and preventing the lead weight from pulling the cableway support through the steel cable.
