Bird repelling device for mud flat crab culture

Abstract

The invention discloses a bird repelling device for mud flat crab culture. For the problems that existing bird repelling equipment for aquatic crab culture does not have long-term usability, and is poor in effect, high in cost, limited in repelling range and the like, now the scheme is proposed as follows: the device comprises a through hole and a buoy, wherein support legs are fixed to an outer wall of the top of the buoy through bolts; a storage battery is fixed to the outer wall of one side of each support leg through a screw; a striking mechanism is connected to the outer wall of each storage battery through a thread; a motor is fixed to the outer wall of the bottom of each storage battery through the screw; a threaded rod is fixed to the top end of an output shaft of each motor through the screw; and a turning plate is fixed to the top end of each threaded rod through the screw. A rotating shaft is driven by the turning plate to rotate, mud is dug out when a digging bucket rotates, sounds are generated when a long rod collides with a percussion gong to repel birds, and the mud is projected to the distance at the moment to repel distant flying birds, so that the bird repellingrange is widened, the use cost is low, the effect is good, long-term usability is achieved, and the bird repelling device is not prone to being seen through.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a bird repelling device for raising crabs on tidal flats. Background technique [0002] Bird repelling is also called bird repellent, which is called bird repellent in English. In a broad sense, all means to prevent harmful birds from invading their own territory, such as farms, orchards, wind power plants, and military and civilian airports, which endanger their labor results or equipment safety, are called bird repellent. Bird repelling, among which seagulls and other flying birds need to be placed to feed aquatic products in aquaculture. Blue crabs are a kind of aquatic products with high value. During the period of blue crab seedlings and moulting, flying birds are extremely vulnerable, resulting in a large amount of property loss, so it is necessary to formulate anti-bird and repellent measures during aquaculture. [0003] The existing bird repelling methods generally u...

Problems solved by technology

[0004] Based on the existing problems of long-term usability, poor effect, high cost and limited repelling range of the existing bird repelling equipment for crab breeding in aquatic products, and the technical problem that flying birds have a high IQ, and the bird repelling equipment is easily broken, the present invention proposes A bird repellent device for raising crabs in tidal flats
