Description

The anti-jellyfish method and device of the anti-shark in bathing beach
Technical field
The present invention relates to a kind of protective net apparatus, in particular to a kind of bathing beach means of defence and device.
Background technique
Bathing beach is built up on littoral seabeach for tourist's swimming, solarization sunbath and the other movement overseas of progress Place.When tourist, which plunges into the commercial sea, to swim, some animals (especially jellyfish and shark) in seawater can threaten to swimmer, this As one of safety problem important in bathing beach.
The method of the anti-shark of anti-jellyfish of bathing beach mainly uses fishing net that outdoor bathing place fences up at present, such as Chinese patent public affairs It opens No. CN1057500C and provides a kind of seaside protecting network and compared with common shark net, the periphery of this seaside protecting network is set A continuous protective barrier is set.The barrier is stretched by the direction of the periphery seaward of protective net, and provides one to ship is carried out It is evident that caution sign, and prevents one that carrys out ship barrier in kind.But this seaside protecting network can only individually prevent shark Swim into, can not simultaneously jellyfish and shark are stopped.
For another example Chinese patent discloses No. CN102717881B and provides a kind of anti-jellyfish shark net tool in bathing beach, packet The rete cord and attachment component for including and being laid in around bathing beach while blocking the mesh sheet of jellyfish and shark, support and fix mesh sheet, Wherein mesh sheet is that the cable for being greater than 42tex7 × 3 by rugosity weaves, and mesh is 2a=50.0mm or 2a=100.0mm, net Purpose casing coupling coefficient is E=0.707.The invention passes through the material and thickness of selection cable, the size of mesh and casing coupling, gang rope The material and size of material and thickness, float and sinker play the effect for stopping jellyfish and shark simultaneously in turn, but when sea When having wind waviness, wave will drive the especially jellyfish of the unknown object in seawater and float, anti-only according to one layer in seawater in this way The anti-shark of jellyfish can not stop jellyfish to climb over netting gear by wave to enter in bathing beach, and then cause to the tourist in outdoor bathing place It is dangerous.
In conclusion existing technology can not play the role of the anti-jellyfish of anti-shark simultaneously, need at present it is a kind of can be simultaneously The method and device of the anti-anti- jellyfish of shark.
Summary of the invention
The object of the present invention is to provide a kind of construction method of three-dimensional anti-anti- jellyfish net of shark, can quickly assemble and just It is safeguarded in replacement.
According to an aspect of the present invention, a kind of anti-jellyfish method of the anti-shark in bathing beach is provided, this method includes following step It is rapid: (1), to prepare the frame-shaped shark net module that several block lengths are 5~10m and width is 2~5m, shark net module includes at least Two layers of shark net mesh sheet for stopping shark, in the top edge of shark net mesh sheet install it is first exaggerated, in shark net mesh sheet Lower edge installation the first infraclass and in the cutting installed respectively on two sides of shark net mesh sheet, wherein the One it is exaggerated on to install float hook at interval of 0.5~1m, to install a sinker at interval of 0.5~1m in the first infraclass Hook;(2), prepare the anti-jellyfish net module of frame-shaped that several block lengths are 6~15m and width is 2~5m, anti-jellyfish net module packet Include anti-jellyfish net mesh sheet for stopping jellyfish, in the top edge of anti-jellyfish net mesh sheet install it is second exaggerated, in anti-jellyfish net Mesh sheet lower edge installation the second infraclass and in the fixation installed respectively on two sides of anti-jellyfish net mesh sheet Piece, wherein to install a float hook at interval of 0.5~1m on exaggerated in second, fixed in the side of anti-jellyfish net module On piece at interval of 0.05~0.2m install first lantern ring, on the other side fixinig plate of anti-jellyfish net module at interval of 0.05~0.2m installs second lantern ring, also, along from the second exaggerated longitudinal direction to the second infraclass, first set Ring is arranged alternately with the second lantern ring;(3), along the wheel of preset bathing beach in the seawater apart from 20~200m of outdoor bathing place sandy beach Profile is to install one for fixing the spud pile of shark net module at interval of 2~5m, and one end of spud pile is embedded in seabed, separately Sea is stretched out in one end, and the two sidewalls of each spud pile pass through screw respectively and are fixedly connected with a slot part;(4), by each anti-shark The cutting of net module two sides is inserted into respectively in the card slot of the corresponding slot part of two neighboring spud pile, to realize shark net module With the connection of spud pile;And (5), the second infraclass of each anti-jellyfish net module is fixedly connected on each shark net module First is exaggerated, and the first lantern ring and second on the adjacent fixinig plate of two neighboring anti-jellyfish net module is alternately passed through using connecting strand Lantern ring is to link together two neighboring anti-jellyfish net module, to form the anti-jellyfish net of the anti-shark in three-dimensional bathing beach.
