Problems solved by technology

[0004] An acousto-optic integrated fish repelling instrument designed in the prior art can achieve the effect of repelling fish, but if the power is cut off during the repelling process, it may cause the fish to swim back and cause repelling failure, and the range and effect of repelling still have room for improvement

Embodiment 1

[0019] like figure 1 As shown, the design of fish repelling alarm system for underwater engineering blasting construction is mainly composed of DC power supply 1, first pulse generator 2, second pulse generator 201 and repelling sound generator 5. Device 2, the second pulse generator 201, driving away the sound generator 5 are connected, the first pulse generator 2 is connected with the pulse booster 3, the pulse booster 3 is connected with the electrode 4 in water, the second pulse generator 201 is respectively connected with The flash generator 7 and the electromagnetic rod 8 are connected, and the driving sound generator 5 is connected with a loudspeaker 6. The present invention can realize sound, light source, electrode, and electromagnetic driving to drive the fish, and the driving will not cause harm to the fish and only plays a role in driving away. The range is large, and the damage to fish schools caused by underwater blasting construction can be avoided by driving fi...

Embodiment 2

[0028] like figure 1 As shown, the input end of the first pulse generator 2 is electrically connected to the DC power supply 1, and the DC power supply 1 is connected to a storage battery 101. The storage battery 101 is a waterproof storage battery, which can prevent the DC power supply 1 from being powered off during the process of driving fish schools to drive fish to swim back. If the situation occurs, ensure that the power of the fish driving system is sufficient during the driving process, and the storage battery 101 has a strong power storage capacity, a long cycle life, and is not easy to leak. The output terminal of the first pulse generator 2 outputs pulses with a voltage value ≤ 24V. The input terminal of the booster 3 is electrically connected to the output terminal of the first pulse generator 2, and the output terminal of the pulse booster 3 outputs a pulse with a voltage value ≥ 100V. The electrode 4 in the water is composed of a long electrode line 402 and a unif...

Abstract

The invention provides a design of fish-repelling alarm system for underwater engineering explosion mainly formed by a DC power supply, a first pulse generator, a second pulse generator and a repelling sound generator. The DC power supply is respectively connected with the first pulse generator, the second pulse generator and the repelling sound generator; the first pulse generator is connected with a pulse booster; the pulse booster is connected with a water electrode; the second pulse generator is respectively connected with a flicker generator and an electromagnetic bar; and the repelling sound generator is connected with a loudspeaker. Fish clusters can be repelled by sound, light sources, electrodes and electromagnets; damages cannot be made to the fishes during the repelling process; and the great repelling range is achieved, and damage to the fish clusters by underwater explosion construction can be avoided by the repelling work.

Description

technical field [0001] The invention relates to a fish-repelling alarm system, in particular to the design of a fish-repelling alarm system for underwater engineering blasting construction. Background technique [0002] Shock waves are generated during underwater blasting construction, causing damage to fish and fish schools in the construction area, causing damage to marine ecology. It is necessary to drive fish and alarm for underwater blasting construction, for example, the Three Gorges Dam Before the blasting of the third-stage cofferdam, in order to reduce or avoid the damage to fish, especially rare and unique fish, caused by the underwater shock wave generated by the blasting of the third-stage cofferdam of the Three Gorges Dam on the Yangtze River, the HGL-2 type electric catch and stop fish were used before blasting. The machine drove the fish out of the waters endangered by the blasting shock wave. [0003] Prior art such as authorized announcement number CN 10133...
