Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fishery culture net cage, and particularly relates to a zipper type net system manufacturing method. BACKGROUND

[0002] The net is an important component of the net cage and other aquaculture equipment. In particular, the net cage frame with a truss structure inevitably forms a window with a certain area. Therefore, the net needs to be split and fixed outside the net cage frame during actual operation. Therefore, the connection and fixing method between the net and the net cage frame plays a crucial role in the reliability of the net cage. In actual application, the connection and fixing method is as follows: direct binding type, that is, the net is directly bound to the frame structure by binding lines. When the size of the frame structure is too large to be bound, a round pipe and other auxiliary tools are added. This method is simple to install and has good reliability, but the net can only bear the load perpendicular to the frame structure. When the load has a component along the frame structure, the net will slip because it is not constrained. Therefore, this method has certain limitations.

[0003] In order to overcome this deficiency, the patent for invention with Chinese publication number CN115843729A discloses a method for fixing the net of a culture net cage. The method is to add binding pipes and support pipes to the main structure of the net cage to form a net tool, and then fix the net to the net tool. The net includes a net, a side frame and a rope frame. The support pipes are arranged in pairs between the binding pipes and the main structure of the net cage, and the distance between the two support pipes arranged in pairs is pre-set. The end of each rope frame is installed on the side frame by splicing or knotting. Two binding ropes are used to wrap the side frame and the binding pipe at the upper and lower sides of the end of the rope frame installed on the side frame with a pre-set number of turns. The two binding ropes are located between the two support pipes arranged in pairs, thereby fixing the position of the end of the rope frame. Finally, the net and the rope frame are fixed by winding the binding line.

[0004] Although the patent for invention with Chinese publication number CN115843729A can solve the problem that the existing culture net cage cannot bear the load component along the frame direction, the above-mentioned connection and fixing method not only needs to add multiple sets of support pipes and binding pipes to the net cage frame to provide binding positions for the net, but also changes the overall structure and weight of the net cage frame, thereby causing the net to be unstable in installation and use, the structure to be complex, and the manufacturing cost to be high. In addition, the net needs to be fixed and connected by winding the net and the binding pipe with multiple sets of binding with a pre-set number of turns during the binding process. The above-mentioned winding method has the problems of complex operation process, long operation time, unstable connection, and low disassembly and assembly efficiency. SUMMARY

[0005] Therefore, one of the purposes of the present application is to provide a liquid seal type micro-pressure protection valve to avoid the shortcomings of the prior art, which can not only solve the problems of unstable use, complex structure and high manufacturing cost of the net cover during installation and use, but also avoid the occurrence of related problems such as complex operation process, long operation time, unstable connection and low disassembly efficiency.
