Coastline fence capable of preventing sharks from invading

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...
