Description

TECHNICAL FIELD

[0001] The present application relates to the underwater blocking technology field, for separating, isolating underwater area, blocking, surrounding underwater objects, in particular to a kind of underwater fixing structure and fixing method of net body. BACKGROUND

[0002] China has a large number of offshore, sea port important facilities, such as offshore oil drilling platform, artificial island, port, dock, etc. Their protection involves water surface and underwater two aspects, wherein underwater protection mainly adopts the way of net body, separates the target to be protected from the outside water area. In this way, it can not only affect the normal flow of seawater, but also prevent the intrusion of objects in the outside water area into important facilities.

[0003] At present, the way of laying underwater net body is usually to use floating ball or floating platform to connect the upper part of the net body, so that it floats on the water surface; the lower part of the net body is equipped with a weight, so that it sinks in the water or the bottom of the water. Due to the fluidity of seawater, only relying on floating ball, floating platform or counterweight cannot effectively fix the net body, and fixed pile, anchor point, shore pile are needed to assist in fixing.

[0004] However, due to the limitation of on-site arrangement environment, especially when connecting with fixed pile, it is difficult to achieve airtightness, resulting in gaps, so that the protected objects and personnel can break through the protection of underwater blocking net by unintentional or intentional way.

[0005] Therefore, it is meaningful to design and develop a method for fixing underwater net body. SUMMARY

[0006] Therefore, the present application provides a kind of underwater fixing structure and fixing method of net body, can solve the problem that the existing underwater blocking net is easy to appear gap when connecting with underwater pile, reduce the leakage rate of blocking net, improve the safety performance of the whole blocking net.

[0007] The embodiment of the present application discloses a kind of underwater fixing structure of net body, including net body, pile and hook, pile is fixed underwater, a plurality of hooks are installed on pile, hook includes inner hook and outer hook, inner hook is fixed on one side of pile, outer hook is fixed on the outer side of inner hook, each pile is provided with at least 2 hooks distributed in parallel, one side of net body is installed on the inner hook of two hooks of one pile, the other side of net body is installed on the outer hook of two hooks of another adjacent pile, two inner hooks and two outer hooks of one pile are installed with net body.

[0008] In an embodiment of the present application, the hook is provided with 2 groups, and each group of hooks is vertically distributed.

[0009] In an embodiment of the present application, the pile body is a cuboid, the two groups of hooks are located on the same face of the pile body, one end of the net body is installed on the two parallel inner hooks of the same pile body, the other end of the other net body is installed on the two parallel outer hooks, and one net body is connected between the two pile bodies.

[0010] In an embodiment of the present application, the inner hooks and the outer hooks are both arc-shaped, and the outer hooks are welded on the circular arcs of the inner hooks.

[0011] The embodiment of the present application further discloses an underwater fixing method of the net body, comprising the following steps:

[0012] The right end of the first net body is installed on the inner hooks of the two parallel hooks on the left pile body;

[0013] The left end of the second net body is installed on the outer hooks of the hooks on which the first net body is installed on the left pile body;

[0014] The right end of the second net body is installed on the inner hooks of the two parallel hooks on the right pile body;

[0015] The left end of the third net body is installed on the outer hooks of the hooks on which the second net body is installed on the right pile body;

[0016] The other net bodies are installed according to the above steps in sequence.

[0017] In an embodiment of the present application, one end of each net body is fixed on the inner hooks of the hooks of the pile body, and the other end is fixed on the outer hooks of the hooks of the other pile body.

[0018] In an embodiment of the present application, the net body and the hooks are fixed by using a cable tie, a shackle or a knot.

[0019] The present application solves the problem that the invading object invades through the gap at the connection position of the pile body by fully covering the net body on the fixed pile body and covering the gap at the connection position of the adjacent net bodies with the pile body.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] As shown in the figure, this embodiment of the invention discloses an underwater fixing structure for a net, including a net, a pile 1, and hooks 2. The pile is fixed underwater, and a plurality of hooks are installed on the pile. Hook 2 includes an inner hook 21 and an outer hook 22. The inner hook is fixed on one side of the pile, and the outer hook is fixed on the outside of the inner hook. Each pile has at least two parallel hooks. One side of the net is installed on the inner hook of two hooks of one pile, and the other side of the net is installed on the outer hook of two hooks of another adjacent pile. The net is installed on both the inner hook and the outer hook of one pile.

[0025] In one embodiment of the present invention, the hooks are provided in two groups, with each group of hooks vertically distributed.

[0026] In one embodiment of the present invention, the pile body is a cuboid, the two sets of hooks are located on the same side of the pile body, one end of the net body is installed on two parallel inner hooks of the same pile body, one end of the other net body is installed on two parallel outer hooks, and a net body is connected between the two pile bodies.

[0027] In one embodiment of the present invention, both the inner hook and the outer hook are arc-shaped, and the outer hook is welded onto the arc of the inner hook.

[0028] like Figure 1 As shown in the figure, this invention also discloses an underwater fixation method for a net, comprising the following steps:

[0029] Install the right end of the first net body 22 onto the inner hook 31 and inner hook 32 of the two parallel hooks on the left pile body 11.

[0030] Install the left end of the second net body 21 onto the outer hook 41 and outer hook 42 of the hook on the left pile body 11 where the first net body has been installed;

[0031] Install the right end of the second net body 21 onto the inner hook 33 and inner hook 34 of the two parallel hooks on the right side pile body 12;

[0032] Install the left side of the third net body 23 onto the two outer hooks 43 and 44 on the right side pile body 12 that are used to install the hooks of the second net body 21; Figure 1 The hooks are placed vertically, such as Figure 2As shown.

[0033] Other nets are installed according to the above steps in turn.

[0034] In an embodiment of the present application, one end of each net is fixed to the inner hook of the pile hook, and the other end is fixed to the outer hook of the hook of another pile.

[0035] In an embodiment of the present application, the net and the hook are fixed by using a cable tie, a shackle or a knot.

[0036] The installation position of the conventional net and the pile is prone to have a larger gap, and the embodiment of the present application sets the inner hook and the outer hook on the pile, and the net needs to be installed on the two hooks on the pile, so that two layers of nets are covered on the same pile, and the gap that may occur is shielded, solving the problem of a large gap occurring when the underwater net and the pile are fixed. The alternating connection of the double-layer net and the inner and outer hooks makes the installation method regular, facilitating personnel operation and maintenance.

[0037] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
