Underwater anti-dragging type fixed detection device

Abstract

The invention relates to an underwater anti-dragging type fixed detection device. The device is composed of an anti-dragging shell (1), a spherical sealed cabin (2), a fixing base (3), a sealed cabinfixing device (4) and shell and base connecting pieces (5); the spherical sealed cabin (2) is arranged in the upper surface of the anti-dragging shell (1); the spherical sealed cabin (2) is connectedwith the fixing base (3) through the sealed cabin fixing device (4); the anti-dragging shell (1) is connected with the fixing base (3) through the shell and base connecting pieces (5); the anti-dragging shell (1) is in the shape of a circular truncated cone; the side surface of the anti-dragging shell (1) is composed of a metal perforated plate (11); and fixing frames composed of metal pipes are arranged on the upper surface and lower surface of the anti-dragging shell and are integrally welded together with the metal perforated plate (11). The underwater anti-dragging type fixed detection device can be stably fixed underwater, is not influenced by water flow and can be effectively prevented from being hooked by a trawl net or other fishing equipment; and the underwater anti-dragging typefixed detection device can realize an effective anti-dragging function so as to obtain real data and provide reliable data for marine scientific investigation.

Description

technical field [0001] The patent of the present invention relates to a detection device, specifically to a signal detection device near a fixed point that can effectively prevent dragging underwater, and belongs to the technical field of marine engineering. Background technique [0002] my country has a vast sea area, totaling 3 million square kilometers. The East China Sea continental shelf is 200-600 kilometers wide, and the South China Sea continental shelf is 180-250 kilometers wide. The seabed is rich in resources. The total area of ​​seabed oil is more than 1 million square kilometers, the geological reserves are 10 billion tons, and the proven mineral deposits are 4.36 million tons. With the increase of population, the amount of resources per capita is getting less and less, and the development of seabed resources has been paid more and more attention by people. my country has a vast land and abundant resources, and is rich in marine resources. To protect our country...
