Embodiment Construction

[0016] Below in conjunction with accompanying drawing, the present invention is described in detail:

[0017] A multi-layer multi-layered fish reef, including a first suspended fish reef 1, a second suspended fish reef 2 and a positioning anchor 3, the first suspended fish reef 1 is connected to the second suspended fish reef 2 by a rope, and the second suspended fish reef 2 The positioning anchor 3 is connected by a rope; the first suspended fish reef 1 is composed of a cover plate 4 and a base 5, and the cover plate 4 and the base 5 form a hollow cavity. The device is connected with an airbag device; the inflation device includes an inflation pipeline 6 and a valve arranged on the inflation pipeline, the valve can prevent seawater from entering the airbag, save the drainage operation of the airbag by an external inflator, and directly inflate the airbag; the airbag device includes an airbag 7 And the protective bag 8 that is coated on the outside of the air bag, the protecti...

Abstract

The invention relates to a multiple-water-layer propagation fish shelter which is characterized by comprising a first suspension fish shelter, a second suspension fish shelter and a location anchor, wherein the suspension fish shelter is connected with the second suspension fish shelter via a rope; the second suspension fish shelter is connected with the location anchor via a rope; the first suspension fish shelter comprises a cover plate and a base which define a hollow cavity body; an inflation device is arranged on the cover plate; the inflation device located in the cavity body is connected with an air bag device; the second suspension fish shelter is a ball casing which is in a hollow structure; a plurality of irregular holes are formed in the surface of the ball casing; an anchor body of the location anchor is internally provided with a plurality of accommodation cavities; the accommodation cavities are internally provided with barbs; the barbs are rotationally connected with convex blocks on the anchor body via pin shafts; limiting blocks are arranged outside the accommodation cavities; a conical cavity is arranged below the anchor body; and an eccentric block is arranged in the conical cavity. The shelter can regulate suspension depth for manual propagation, has good stability, low dragging possibility and excellent ecological performance, can carry out multiple-water-layer propagation and has a good propagation effect.

Description

technical field [0001] The invention relates to a multi-water layer multiplication fish reef. Background technique [0002] As a fishery habitat improvement technology, artificial reef construction has played an important role in restoring fishery habitats and increasing fishery resources. The current research focus of fish reef technology is on the scientific research on the mechanism of artificial reef environment, while artificial reef As an important part of artificial reef construction, there is no in-depth research on the delivery technology and method. The deployment of artificial reefs plays a pivotal role in all aspects of artificial reef construction. Safe, accurate and efficient deployment of artificial reefs will not only enable artificial reefs to exert their maximum habitat transformation function, but also It saves a lot of manpower and material resources for the construction of artificial fish reefs. Contents of the invention [0003] Aiming at the pr...
