Example Embodiment

[0044] Example 1

[0045] The disaster jellyfish mincing device of the present invention must be used before the jellyfish becomes sexually mature, because the jellyfish cannot be minced blindly after sexual maturity, otherwise, the sexual reproduction of the jellyfish will be stimulated and the outbreak will occur the following year.

[0046] figure 1 It is a schematic diagram of the disaster jellyfish crushing device of the present invention, wherein:

[0047] The bottom of the net of the trawl net 1 is provided with a net ring 2 composed of solid steel rings; 16 steel wires 21 are arranged inside the net loop 2, which are arranged in the shape of umbrella ribs, with a diameter of ∮ 2mm; the trawl net 1 is in the shape of a bag;

[0048] The net port of the trawl net 1 is provided with two side gangs 3, namely: side gang I31 and side gang Ⅱ 32; the material is stainless steel pipe, the end has a head, the length is 2000mm, the outer diameter is 20mm, and the inner diameter ...

Example Embodiment

[0059] Example 2

[0060] In the coastal waters near the beach or industrial water intake, the water body is relatively shallow, and it is appropriate to use nets to intercept and collect jellyfish. image 3 The system shown is a schematic diagram of a sea area disaster jellyfish collection system at a beach or an industrial water intake. The fundamental purpose is to prevent large jellyfish from entering the bathing beach and industrial water intake, and to ensure the health of the beach and the safety of industrial water.

[0061] image 3 and Figure 4 The jellyfish collection system described in includes intercepting net 9, jellyfish collection channel 10 and bubble generator 11, wherein:

[0062] The jellyfish collection channel 10 is a U-shaped trough surrounded by three planes, and the opening of the U-shaped trough faces away from the coast; the two ends of the opening of the U-shaped trough are respectively connected with intercepting nets 9 (that is, the jellyfish ...

Example Embodiment

[0065] Example 3

[0066] Under specific circumstances, the intercepting net can be formed by connecting the sides of the monolithic net end to end; the design description of the monolithic net:

[0067] The interception net is designed to stop the collection of large jellyfish, but also to ensure that swimmers are not entangled. Therefore, a comparison and consideration were made in the selection of the material and thickness of the wire, the size and narrowing of the mesh, the material and thickness of the rope, and the material and size of the float and sinker. Specifically, the interception net described in Embodiment 1 is composed of the following monolithic nets:

[0068] 1. Determine the size of the large jellyfish to use the corresponding mesh, the mesh is 2a=50.0mm and 2a=100.0mm.

[0069] 2. The net wire should be appropriately thickened (>∮2mm) compared with the net wire of the fishing net to reduce its ability to thorn and entangle.

[0070] 3. The mesh reductio...

Abstract

The invention discloses a disaster jellyfish emergency disposal method. According to the disaster jellyfish emergency disposal method, a mode that an emergency disaster jellyfish mincing device and a jellyfish collection system are combined is adopted, wherein a hollow steel wire is arranged at the bottom of a drag net; when the drag net is driven to quickly advance by a ship, jellyfishes gathered at the bottom of the drag net are crushed by means of water flow impact pressure; at a region with relatively shallow water, the disaster jellyfish collection system is combined; a jellyfish collection passage designed in the disaster jellyfish collection system is positioned at an included angle formed by a W-shaped interception net; and on the tide, the jellyfishes are introduced into and gathered to the jellyfish collection passage by the interception net under the action of the tide and then are killed off in a centralized way. According to the disaster jellyfish emergency disposal method, a large number of disaster jellyfishes are effectively disposed, the ecological hazard of the jellyfishes can be reduced, and a quick, high-efficiency and convenient disposal effect can be performed on the jellyfish disaster which outbreaks rapidly.

Description

technical field [0001] The invention belongs to the field of marine fishery devices, and in particular relates to a large-scale disaster jellyfish crushing device. Background technique [0002] In recent years, jellyfish disasters, as a new type of ecological disaster, have attracted great attention from the governments and researchers of coastal countries around the world. The outbreak mechanism and emergency warning and disposal technology of large jellyfish have become a hot spot in the research of marine ecological disasters. The outbreak of large jellyfish It not only affects fishery production, but also destroys the structure of the food chain, leading to an imbalance in the ecosystem. [0003] At present, there are few disaster elimination and disposal methods for large jellyfish at home and abroad. Japan has research on large-scale jellyfish monitoring and early warning systems and disposal methods. It mainly uses diversified means such as ship monitoring, remote se...
