Problems solved by technology

[0002] Shoreline guardrails are usually used to separate deep water areas from shallow water areas. People usually operate in shallow water areas. Sharks are very ferocious creatures in the ocean. When people are active in the ocean, they may be threatened by sharks. However, existing shoreline barriers are not very good at keeping sharks out

Embodiment 1

[0030] refer to Figure 1-7 , a coastline guardrail for preventing shark intrusion, comprising a plurality of upright structures equidistantly arranged and a protective structure connected between two adjacent upright structures, the upright structure includes a sleeve 9 and a rotating rod 6, and the sleeve 9 is poured In the embankment, the top of the sleeve column 9 is provided with a threaded groove, and the rotating rod 6 is threadedly connected with the sleeve column 9 at the threaded groove, and one side of the sleeve column 9 is provided with a first through hole, and the sleeve column 9 is in the first through hole. Bolts 901 are provided at the through holes, and the rotating rod 6 can be fixed by rotating the bolts 901 without falling off. There is a rotating sleeve 8, and the rotating sleeve 8 is sleeved on the outside of the rotating rod 6. Through the rotation of the rotating sleeve 8 and the elasticity of the first spring 5, when the seawater flows, the protectiv...

Embodiment 2

[0037] refer to Figure 8 , a shoreline guardrail for preventing shark invasion. Compared with Embodiment 1, in order to make the installation of the coastline guardrail more stable in this embodiment, both sides of the rotating rod 6 are welded with a rotating shaft 23, and the outside of the rotating shaft 23 is welded with a first hook. Ring 24, one side of the first shackle 24 is equipped with a steel cable 25, and one end of the steel cable 25 is provided with a second shackle 26, and the bottom end of the second shackle 26 is welded with a fixed column 27, the fixed column 27 are all poured in the embankment, and the steel cables on both sides of the rotating rod 6 make the rotating rod 6 not shaken by seawater fluctuations to enhance stability.

[0038] During use, this device is energized first, and the inside of the protective frame 1 can be energized through the rubber tube 18, so that the lighting lamp 3 can emit light. Extend the rubber tube 18 to avoid damage to ...

Abstract

The invention belongs to the technical field of protective fences, and particularly discloses a coastline fence capable of preventing sharks from invading. The coastline fence capable of preventing the sharks from invading is used for solving the problems that an existing coastline fence is not high in design strength and cannot well prevent the sharks from entering. According to the technical scheme, the coastline fence capable of preventing the sharks from invading comprises a plurality of stand column structures arranged at equal distance and protective structures connected between every two adjacent stand column structures, the stand column structures comprise sleeve columns and rotating rods, the sleeve columns are poured into a dam, and threaded grooves are formed in the top ends ofthe sleeve columns; and the rotating rods are in threaded connection with the sleeve columns at the positions of the threaded grooves, first through holes are formed in one sides of the sleeve columns, and the sleeve columns are provided with bolts at the positions of first through holes. According to the coastline fence capable of preventing the sharks from invading, irradiation orange light is additionally arranged, reflection ability and refraction ability are improved, and the sharks can be expelled; and meanwhile, warning light illuminating can be carried out at night, fishing boats are prevented from hitting the fence, the fence is more stable through wire ropes on two sides, and a glass film prevents the coastline fence from being damaged by the pulling of sea grass.

Description

technical field [0001] The invention relates to the technical field of guardrails, in particular to a coastline guardrail for preventing shark invasion. Background technique [0002] Shoreline guardrails are usually used to separate deep water areas from shallow water areas. People usually operate in shallow water areas. Sharks are very ferocious creatures in the ocean. When people are active in the ocean, they may be threatened by sharks. However, existing shoreline barriers are not very good at keeping sharks out. [0003] The existing coastline safety guardrails are usually used to prevent people from entering deep water areas when they are active in shallow water areas, and can block people's activities. The ability to withstand is limited, and it may be destroyed when it is impacted. When expelling fish through smell, it will pollute water resources. Expelling sharks through sound waves will also cause certain damage to the human body. Therefore, we have proposed a sha...
