Problems solved by technology

[0007] At present, there is still a lack of research on emergency response technology for large-scale jellyfish disasters in the nearshore and farshore oceans at home and abroad. The device of the present invention and its use method can provide technical support for the healthy development of coastal tourism and the safe operation of coastal electric power industry. It is of great significance to reduce the harm of jellyfish in coastal areas and protect public health

Embodiment 1

[0045] When using the disastrous jellyfish crushing device of the present invention in the offshore sea area, it must be used before the jellyfish body is sexually mature, because the jellyfish cannot be crushed blindly after sexual maturity, otherwise it will stimulate the sexual reproduction of the jellyfish and cause an outbreak in the next year.

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

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

[0048] The net port of the trawl net 1 is provided with two side frames 3, namely: side frame I 31 and side frame II 32; the materials are all stainless steel tubes, with heads at the ends, 2000 mm in length, 20 mm in outer diameter, and 18 mm in inner diamete...

Embodiment 2

[0060] In the coastal waters near the bathing beach or the industrial water intake, the water body is relatively shallow, and it is suitable to adopt the method of intercepting and collecting jellyfish with nets. image 3 The system shown is a schematic diagram of the disaster jellyfish collection system in the bathing beach or 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 bathing beach and the safety of industrial water.

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

[0062] The jellyfish collection channel 10 is a U-shaped groove surrounded by 3 planes, and the opening of the U-shaped groove is facing away from the coast; the two ends of the opening of the U-shaped groove are respectively connected with interception nets 9 (...

Embodiment 3

[0066] Specifically, the interception network can be formed by connecting the sides of the single-chip network end to end; the design description of the single-chip network:

[0067] The purpose of the interception net is to stop the collection of large jellyfish, but also to ensure that swimmers are not entangled. Therefore, comparisons and considerations have been made in the selection of the material and thickness of the network cable, the size and shrinkage of the mesh, the material and thickness of the rope, and the material and size of the float and sinker. Specifically, the interception network described in Embodiment 1 is composed of the following single-chip network:

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

[0069] 2. The net wire should be thicker (>∮2mm) than that of the fishing gear to reduce its ability to hang and entangle.

[0070] 3. The mesh shrinkage coefficient is designed ...

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...
