Electronic pulse fish trapping device

Abstract

The invention relates to an electronic pulse fish trapping device which comprises a control module and conductive rods, wherein the control module is positioned between a power supply source and the conductive rods and used for generating high-voltage pulses according to an input voltage from the power supply source and controlling the time interval of generating the high-voltage pulses, and the conductive rods are used for receiving the high-voltage pulses from the control module and releasing the high-voltage pulses into water. According to the invention, the conductive rods are arranged linearly before the bell-mouth entrance of the floodway of a water reservoir, where the water flow is slow, to form an electric fence with the same width as the floodway and generate a high-voltage pulse current stimulation field in the direction perpendicular to the electric fence. If the fish stocks swim close to the electric fence, the fish stocks swim back under the stimulation of the special pulse currents, which achieves the purpose of preventing escape of fish.

Description

technical field [0001] The invention relates to a fish blocking device, in particular to an electronic pulse fish blocking device. Background technique [0002] The traditional method of preventing fish from escaping with fishing nets. Summer and autumn are the rainy seasons in our country. When floods suddenly overflow and fish escape, it brings huge economic losses to professional fish farmers. Traditional escape prevention: to prevent escape in rivers, use cages or separate nets. To prevent fish from escaping in reservoir ponds, the upstream and downstream (spillway mouths set up to ensure the safety of the reservoir) outlets are to prevent fish from escaping by blocking fishing nets horizontally. 2. Disadvantages of traditional fishing nets to prevent fish from escaping A. Serious safety hazards have been laid for the safe operation of reservoirs and embankments. , will quickly block the meshes of the fishing nets used to block fish, and the blocked meshes will soon lo...

2. Disadvantages of traditional fishing nets to prevent fish from escaping A. Serious safety hazards have been laid for the safe operation of reservoirs and embankments. , will quickly block the meshes of the fishing nets used to block fish, and the blocked meshes will soon lose their normal combing ability. During the flood discharge stage, the water flow is rushing, and it is impossible to remove the scum on the net in time, let alone replace it in time The flow through the network has resulted in a sharp drop in the spillway and river flood discharge, which has brought serious safety hazards to the safe operation of the reservoir.

B. The efficiency of blocking fish is low. With the traditional method of blocking fish with fishing nets, it is impossible for the fishing net to completely match the terrain, and there are also scratches and damages of large floating objects. The anti-escape effect is low, and the average anti-escape rate is less than 75%.
