Abstract

The invention discloses a trawling net for emergency disposal of hairy shrimps in waters adjacent to a nuclear power plant, comprising: a hull, a strut and a trawling net connected to the strut, the strut extends to both sides of the forward direction of the hull, the The struts are movably connected with the hull, and the struts are provided with a number of rollers, and the trawl is retracted through the corresponding rollers; the hull is provided with a winch device, and the trawl and the winch The net device is fixedly connected; the hull is provided with a stretching mechanism, and the stretching mechanism is connected to the free end of the strut through a pull rope. The stretching mechanism includes a cylinder, and the cylinder rotates to the The stay rope is retracted; the winch device and the stretching mechanism are connected through a straight rod, and the winch device and the stretching mechanism rotate synchronously; The invention can automatically control the distribution shape and area of ​​the trawl net through the sonar probe to realize automatic shrimp catching.

Description

technical field [0001] The invention relates to a hairy shrimp fishing device, in particular to a trawling net for emergency treatment of hairy shrimps in waters adjacent to nuclear power plants. Background technique [0002] According to the official website of the National Nuclear Safety Administration, on March 24, 2020, Unit 4 of Yangjiang Nuclear Power Plant was operating at full power. Due to marine organisms (shrimp groups) entering the seawater circulating water filtration system, the high pressure difference of the rotating filter caused the No. 2 seawater The circulating water pump tripped, and the staff reduced the power of the unit to 600,000 kilowatts according to the plan. Then, the pressure difference of the rotary filter of the seawater circulating water filtration system was high, which caused the trip of the No. 1 seawater circulating water pump, and the tripping of the two seawater circulating water pumps triggered the condenser failure signal , causing th...
