An Underwater Stealth Blocking Device with Distributed, High-Power Power Modules

Abstract

The invention relates to an underwater invisible blocking device with a distributed high-power power supply module. The underwater invisible blocking device includes: a DC power supply device, a water surface pulse generator, a conductor electrode, and an underwater ballast. The DC power supply device uses To convert the alternating current generated by the mains or generator into the stable direct current required by the water surface pulse generator; the output end of the DC power supply device is connected to the input end of the water surface pulse generator, and the water surface pulse generator is used for The DC power generated by the DC power supply device is converted into a high-voltage pulse with adjustable positive and negative polarity, which drives the conductor electrode to form a pulsed electronic block. The water surface pulse generator adopts a distributed and high-power form, which makes the invisible blocking device simple and efficient, can ensure the safety of blocking creatures, and at the same time provide uninterrupted power supply.

Description

technical field [0001] The invention relates to the technical field of power electronic engineering, in particular to an underwater invisible blocking device of a distributed high-power power supply module. Background technique [0002] In large-water aquaculture farms, nuclear power plant water intakes and other occasions, in order to achieve effective interception of aquatic organisms or closed frogmen, the traditional method is to use nylon nets. However, the amount of disassembly and assembly of nylon mesh is large, and it is easy to adhere to aquatic organisms, which affects the water flow and normal boating. It needs frequent cleaning and maintenance, and has a great impact on the surrounding water environment. [0003] In recent years, the inductive effect of organisms on the electric field has received extensive attention from the academic circles at home and abroad. The inductive effect and the sun-trending effect of organisms under the condition of pulsed electric ...

Problems solved by technology

This kind of power supply has the disadvantages of low power factor on the input side and large harmonic content; the output voltage cannot be automatically and continuously adjusted, and can only be adjusted manually in stages.

In particular, the power frequency transformer is bulky, which seriously affects the power density and portability of the pulse power supply device, causing inconvenience in the transportation and installation of the power supply
