Abstract

The invention relates to the technical field of marine fish expelling equipment, and discloses a PLC-based sound wave fish expelling system for a power plant coal unloading wharf. The PLC-based soundwave fish expelling system comprises a first motor and two supporting plates, the first motor is fixedly arranged on the left side wall of the supporting plate at the left side, and a reciprocating lead screw and a first rotating rod are arranged between the two supporting plates; the rod walls of the two ends of the reciprocating lead screw and the rod walls of the two ends of the first rotatingrod are rotationally connected with the side walls of the corresponding supporting plates through first bearings correspondingly, the left end of the reciprocating lead screw penetrates through the supporting plate at the left side and is fixedly connected with the output end of the first motor, and the reciprocating lead screw and the first rotating rod are in transmission connection through a transmission mechanism; and the rod wall of the first rotating rod is movably sleeved with a sleeve, limiting grooves are symmetrically formed in the inner wall of the sleeve, and limiting blocks are symmetrically and fixedly arranged on the rod wall of the first rotating rod. According to the PLC-based sound wave fish expelling system, the sound wave emission direction is adjusted, and the fish repelling effect is ensured.

Description

technical field [0001] The invention relates to the technical field of marine fish driving equipment, in particular to a PLC-based acoustic wave fish driving system for coal unloading docks of power plants. Background technique [0002] The propagation of the vibration generated by the sounding body in the air or other substances is called a sound wave. The sound wave propagates in all directions through various media. The sound wave is usually a longitudinal wave, and there are also transverse waves. The particles where the sound wave goes vibrate near the equilibrium position along the direction of propagation. The propagation of sound waves is essentially the transfer of energy in the medium. [0003] Among them, the patent No. CN110963545A discloses a method and system for driving away underwater organisms using high and low frequency sound wave transducers. Acoustic transducer, using low-frequency acoustic transducer to drive out fish in the water body, using high-freq...
