Cultured fish grate connection structure and manufacturing method thereof

Abstract

The invention relates to a cultured fish grate connection structure which comprises a longitudinal pipe, a transverse pipe and a connection piece. The connection piece comprises a first main pipe and a first side pipe. A first opening and a second opening are formed in the two ends of the first main pipe respectively. A channel allowing the transverse pipe to pass through is formed between the first opening and the second opening. The cultured fish grate connection structure further comprises a first limiting piece and a second limiting piece. The first limiting piece corresponding to the first opening is arranged on the transverse pipe. The second limiting piece corresponding to the second opening is arranged on the transverse pipe. One end of the first side pipe is perpendicularly connected with the first main pipe. The other end of the first side pipe is connected with the longitudinal pipe. The invention further provides a manufacturing method of the cultured fish grate connection structure. By the adoption of the technical scheme, the situation that the joint of the transverse pipe and the connection piece and the joint of the longitudinal pipe and the connection piece crack can be reduced greatly, the wind wave resistance of the cultured fish grate connection structure is improved effectively, and the service life of the cultured fish grate connection structure is prolonged effectively.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a connection structure for aquaculture fish rafts, and also relates to a manufacturing method of the connection structure for aquaculture fish rafts. Background technique [0002] At present, the increasing scale of offshore aquaculture and the development of ports have reduced the area of ​​offshore aquaculture, increased the density of aquaculture, and seriously polluted the seawater. In order to solve the problem of aquaculture safety and expand the aquaculture space, aquaculture fish rafts are generally used in the mariculture industry. [0003] There are several ways to make farmed fish steaks on the market: [0004] The first method: use screws to directly penetrate and lock the criss-cross pipes up and down. It is necessary to use a drilling machine to drill holes and then pass bolts to fix them. The installation process is cumbersome, the efficiency is low, and the ...

Problems solved by technology

[0004] The first method: use screws to directly penetrate and lock the criss-cross pipes up and down. It is necessary to use a drilling machine to drill holes and then pass bolts to fix them. The installation process is cumbersome, the efficiency is low, and the labor cost of installation is very high. The joints of the pipes are pierced through holes, causing the pipes to break easily at the positions with holes when they are impacted by waves on the sea surface, or the bolts and plastic pipes are rubbed for a long time to make the bolts fall off when the plastic pipes are drilled. Risk of use

[0005] The second method: use four-way or six-way joints to fix the pipes together by welding the end faces. Since the hot-melt welding process is used, the quality is higher than the first method. This connection structure includes horizontal pipes, The longitudinal pipes and the connectors connecting the horizontal pipes and the longitudinal pipes are fixedly connected. With this connection structure, the six-way or four-way joints are the stress concentration points at the joints between the horizontal and the longitudinal. Under the impact, there will be fractures at the joint, and the stability of the entire cultured fish raft is still unsatisfactory

In this way, although the assembly is more convenient, because the position of the pipe on the semicircular fastener is the stress concentration point, under the repeated impact of wind and waves for a long time, the edge of the connection between the pipe and the semicircular fastener will break , which ultimately affects the stability of the entire cultured fish raft

Moreover, with this connection structure, the horizontal pipes and the longitudinal pipes are on different planes, and the cultured fish rafts formed by this connection structure have height differences, which is inconvenient for operators to walk and work on the cultured fish rafts.
