Problems solved by technology

The current method of preventing stings and sharks in bathing beaches mainly uses fishing nets to enclose the bathing beaches, but thorns and entanglements often occur. It is not to block jellyfish and sharks, but to catch them
Patents GB2288962A, GB2303283 (same family C N1057500C) disclose seaside shark prevention nets, which cannot block jellyfish and sharks at the same time, and the effect of blocking sharks alone, especially in China's sea area, is not very satisfactory
The connection, laying, management and maintenance of net gear are inconvenient, and there is no good way to combine and arrange them

Embodiment 1

[0039] Example 1 A single-chip network applied to a beach in the East China Sea.

[0040] Bath area: 7000 square meters (200 meters x 350 meters)

[0041] like figure 1 As shown, the new protective monolithic mesh 1 for bathing beaches is woven by a netting machine with a single dead knot using yellow PE42tex7×3 mesh wires. After weaving, it is stretched and heat-set. The components together constitute the protective net gear of the beach, and the cable includes the upper class 2, the lower class 3, the floater class 4, and the sinker class 5. to combine Figure 7 As shown, the left and right edges of the monolithic net 1 can be combined into a whole row.

[0042] like Figure 1-6 As shown, the upper edge of the monolithic net 1 is attached to the upper class 2, and its lower edge is attached to the lower class 3. The length of the monolithic net 1 is divided into three types: 99.00m, 49.50m, and 24.75m; the monolithic net ( 1) There are 12 levels of straightening height:...

Embodiment 2

[0045] The binding method of embodiment 2 monolithic net

[0046]First prepare the cable:

[0047] The upper line 2 and the floater line 4 are 3-strand ropes of polyethylene φ10.0mm, with one left and one right twisted; One of each is used together, and the length of the above-mentioned cables is 100.00m, 50.50m, 25.75m and so on;

[0048] Secondly, different monolithic nets are bound separately

[0049] 1. If figure 1 , mesh 2a=50.0mm, 2800T single-chip mesh, such as figure 2 , and mesh 2a=100.0mm, 1400T monolithic mesh, the binding length with the upper and lower lines is 99.00m, and the two ends of the monolithic mesh are left blank with a distance of 6, 0.50m, the upper and lower lines The total length of 100.00m;

[0050] The binding method of 2800T is: 600 sections at 99.00m, each section is 165.0mm long, the first section and the last section are tied with 6 meshes, and the remaining sections are tied with 4 meshes;

[0051] The binding method of 1400T is: 600 se...

Abstract

The invention relates to a novel bathing beach protection single net and a bundling method thereof. Left and right edges of the single net can be combined into integral rows around seams; an upper edge of the single net is bundled and attached with a head line; a lower edge of the single net is bundled and attached with a foot line; the single net has three types of lengths of 99.00m, 49.50m and 24.75m, so that the single net is assembled into net rows according to the length-width requirements of a bathing beach; the single net has 12 types of straightening heights of 0.70m, 1.40m, 2.10m, 2.80m, 3.50m, 4.20m, 4.90m, 5.60m, 6.30m, 7.00m, 7.70m, and 8.40m so as to adapt to the requirement on the change of the water depth of the bathing beach; and each single net is divided into a plurality of sections. The novel bathing beach protection single net and the bundling method thereof have the beneficial effects that a plurality of adopted single nets can be connected and combined into an integral-row net tool, are convenient for connection, laying, management and maintenance of the net tool and can be used for simultaneously blocking nettlefishes and sharks.

Description

technical field [0001] The invention belongs to the protection device of the beach, and in particular relates to a new type of protective single-piece net for the beach and its binding method. Background technique [0002] Beaches are places built on coastal beaches for swimming, sunbathing and other sea sports. When swimming, the threat of jellyfish and sharks to swimmers has become one of the important safety issues in beach bathing places. Protective nets for bathing beaches generally include nets laid around the bathing beach to simultaneously block jellyfish and sharks, wires and accessories for supporting and fixing the nets. The anti-stinging and shark-proofing method of present seashore bathing place mainly adopts fishing net to enclose the bathing place, but the phenomenon of stabbing and twining often occurs, instead of stopping jellyfish and sharks, they are caught. Patents GB2288962A, GB2303283 (common family C N1057500C) disclose seaside shark prevention nets,...
