Marine hydrology observation instrument used for ocean wind electricity planning

Abstract

The invention relates to a marine hydrology observation instrument used for ocean wind electricity planning. The marine hydrology observation instrument used for the ocean wind electricity planning comprises a floating platform, wherein a line wheel is fixedly arranged on the top surface of the floating platform, the periphery of the line wheel is fixedly connected with one end of a mooring rope,a hammer is fixedly arranged at the other end of the mooring rope, through holes are respectively formed in the top surface and the bottom surface of each sampling device, the inner walls of the two through holes of each sampling device are respectively fixedly connected with the periphery of the same sleeve, grooves are formed in the two sides of the inner wall of each sleeve respectively, the other end of a second connecting rod in each groove is hinged with one side of the same clamping block, a water inlet is formed in the top surface of each sampling device, a conical plug is movably arranged in each sampling device, an air sac is fixedly arranged on the bottom surface of each sampling device, and an air pump is fixedly arranged in each air sac. The marine hydrology observation instrument provided by the invention can realize accurate sampling on depth of each seawater layer, so that comprehensiveness and accuracy of a hydrologic observation result are guaranteed, and engineeringconstruction of an offshore wind plant is promoted; and seawater can rapidly enter a sampling device, so that sampling efficiency of the marine hydrology observation instrument is improved.

Description

technical field [0001] The invention belongs to the field of hydrological observation, in particular to an ocean hydrological observation instrument for ocean wind power planning. Background technique [0002] Paying attention to and vigorously developing offshore wind power and accelerating the construction of offshore wind power will not only drive the development of marine economy and equipment manufacturing, but also ensure my country's energy security, meet the inevitable requirements of sustainable energy supply, and promote energy conservation and emission reduction. At present, the evaluation of offshore wind energy resources in my country has not been systematically carried out, and the work of marine hydrographic survey and seabed geological survey is relatively weak, and these working conditions are difficult and the cycle is long, which affects the smooth progress of offshore wind farm construction.

Problems solved by technology

At present, the evaluation of offshore wind energy resources in my country has not been carried out systematically, and the work of marine hydrographic survey and seabed geological survey is relatively weak, and these working conditions are difficult and the cycle is long, which affects the smooth progress of offshore wind farm construction.

The traditional method of marine hydrological observation is that the ships arrive at the observation points one by one, drop the current and water depth observation equipment one by one, and observe on board. After the observation time meets the requirements, the measurement efficiency is low, and the equipment is retrieved one by one. Not only is it time-consuming and laborious, but the measurement time cannot Guaranteed to be carried out at the same time, the observation data needs to be merged and sorted, which is very cumbersome and cannot meet the measurement of different seawater depths, resulting in deviations in the measurement results and affecting the accuracy of the measurement results
