Description

Intelligent excrement collection device for carnivorous fishes Technical Field The invention relates to the technical field of fish culture, in particular to an intelligent excrement collection device for carnivorous fishes. Background The intestinal tracts of carnivorous fishes (mandarin fish, weever, largemouth black weever and the like) are short, and the produced excrement has high nitrogen content in the excretion process after ingestion, digestion and absorption, is a main source of harmful substances such as ammonia nitrogen, nitrite and the like in the culture water body, and can not be effectively cleared timely, so that the water quality is extremely easy to deteriorate, thereby causing fish stress and disease breeding and seriously restricting the improvement of culture density and benefit. At present, the excrement collection mode commonly adopted in industrial culture mainly depends on manual salvage or sewage pipe sewage suction, and manual salvage mainly depends on naked eye searching and manual salvage, so that the labor intensity is high, the efficiency is low, and the salvage process is blind. The traditional pool bottom blow-off pipe can generate severe water flow and noise during working, so that the stress of fishes is easy to cause, the fish shoal is easy to be attracted to the vicinity of a blow-off port, the extrusion of the fish shoal is caused, particularly the fishes with spines on the fins of mandarin fish and the like are easy to mutually stab organisms, and the injury and even death conditions occur. Disclosure of Invention Aiming at the defects in the prior art, the invention provides the intelligent excrement collecting device for the carnivorous fishes, which can automatically collect the excrement of the fish shoal without affecting the life of the fish shoal. In order to achieve the aim, the intelligent excrement collection device for the carnivorous fishes comprises a collection mechanism, an adsorption plate and a driving mechanism; The collecting mechanism comprises a collecting cavity and a drain pipe, the collecting cavity is arranged at the bottom of the water tank, the top of the collecting cavity is provided with a plurality of openings communicated with the water tank, and the drain pipe is arranged in the collecting cavity; the adsorption plates are respectively and reversibly arranged at the openings and can close the openings, and a plurality of negative pressure holes are formed in the adsorption plates; the driving mechanism is connected with the adsorption plate and can drive the adsorption plate to turn over. The excrement and urine of shoal of fish is the granule, can sink to the pond bottom gradually after discharging, falls on each adsorption plate, can adsorb excrement and urine on the adsorption plate through the negative pressure hole, and actuating mechanism regularly drives the adsorption plate upset, and one side that has the excrement and urine with the adsorption plate is inhaled and is rotated to collecting the intracavity to separate collecting chamber and pond, can stop adsorbing excrement and urine, and carry out powerful blowdown to collecting chamber through the blow off pipe. The intelligent excrement collecting device for the carnivorous fishes has the beneficial effects that the adsorption plate can adsorb and transfer the excrement at the bottom into the collecting cavity, and the process can not generate severe water flow and noise in the water pool, so that the normal life of a fish farm is not affected. The adsorption plate can also separate the collection cavity and the water pool after transfer so as to facilitate uniform sewage disposal in the collection cavity, and avoid the influence of noise, water flow and the like on the water pool. Further, the bottom of the pool is also provided with a separation net positioned above the adsorption plate. The isolation net can avoid the shoal of fish to be close to the adsorption plate to avoid the adsorption plate to collide with fish when overturning. Further, the collecting mechanism further comprises a scraper which is movably arranged in the collecting cavity, and the end part can be contacted with one side of the adsorption plate facing the collecting cavity. After the adsorption plate drives the adsorbed excrement to turn over to the collecting cavity, the scraping plate moves and contacts with the surface of the adsorption plate through the end part, and the excrement remained on the adsorption plate is scraped off so as to be sucked away by the sewage drain pipe. Further, the adsorption plate is rotationally connected with the inner wall of the opening through a rotating shaft, a gear is sleeved on the rotating shaft, the scraping plate is rotationally connected with the collecting cavity through a second rotating shaft, and the second rotating shaft is sleeved with the gear; The driving mechanism comprises a motor and a rotating shaft III, the motor is arranged in the collecting c
