Description

Technical Field

[0001] The utility model relates to the field of tube sheet connection, and particularly relates to a tube sheet connecting piece. Background Technique

[0002] With the transformation of the global energy structure towards clean energy, marine energy, as a renewable resource, has received increasing attention. In response to the national initiative, the marine photovoltaic industry has been vigorously developed and combined with the marine aquaculture industry. An HDPE (high-density polyethylene) floating fishery-photovoltaic complementary platform has been designed and developed. "Fishery-photovoltaic complementarity" refers to a form of combination of fishery aquaculture and photovoltaic power generation, that is, photovoltaic panels are erected above the water surface for power generation, and precious marine products are cultured in the water area below the photovoltaic panels. The photovoltaic panel array also provides a good shading effect for the cultured precious marine products, forming a new power generation mode of "generating electricity above and culturing below"; the development mode of fishery-photovoltaic complementarity integrates fishery aquaculture and production and processing; by utilizing China's rich marine resources, a photovoltaic power generation system is built in the deep sea, and modern facilities are used for the assembly and matching of fishery underwater, which not only increases the output value of marine resources, but also the photovoltaic power generation in the upper space can provide green electricity for nearby industries and seafood processing industries. The tube sheet connecting piece can be used for the connection and fixation of the photovoltaic panel column and the bottom stay bar of the photovoltaic panel.

[0003] However, for the tube sheet connecting piece in the prior art, the connection between the photovoltaic panel column and the bottom stay bar of the photovoltaic panel is relatively troublesome. When inserting the column into the tube sheet connecting piece, the position of the column needs to be adjusted to fix it with bolts. However, the connection between the column and the tube sheet connecting piece is relatively tight, resulting in unsmooth rotation, making the fixation of the column relatively troublesome. Content of the Utility Model

[0004] The purpose of the utility model is to provide a tube sheet connecting piece to solve the problems put forward in the above background technique.

[0005] To solve the above technical problems, the technical solution of the utility model is a tube sheet connecting piece, which includes a first connecting tube and a second connecting tube. Rotating mechanisms are arranged at the top and bottom positions inside the first connecting tube. The rotating mechanism includes a snap ring, and two groups of rotating grooves are opened on the inner side wall of the first connecting tube;

[0006] Guide grooves are opened on the upper and lower side walls inside the rotating groove. A number of groups of support plates are arranged at the upper and lower ends on the outer side wall of the snap ring. An axial groove is opened on the support plate, and a ball is rotatably arranged inside the axial groove.

[0007] As a further scheme of the utility model: the snap ring is rotatably arranged inside the rotating groove, the bottom of the ball is rotatably arranged inside the axial groove, and the top of the ball is rotatably arranged inside the guide groove.

[0008] As a further solution of the utility model: The support plate is rotatably arranged inside the rotation groove along the guide groove through the cooperation of the ball and the shaft groove.

[0009] As a further solution of the utility model: Three groups of reinforcing hoops are arranged on the outer side wall of the first connecting pipe, fixing screw holes are opened on the outer side of the reinforcing hoops, and a slot is opened on the side wall of the second connecting pipe at the middle position.

[0010] As a further solution of the utility model: Grooves are symmetrically opened on the outer side wall of the second connecting pipe with respect to the slot, and screw grooves are penetrated and opened inside the grooves.

[0011] As a further solution of the utility model: A sealing cap is arranged at the top of the groove, a clamping groove is opened at the middle position of the second connecting pipe, and bolts are arranged inside both the fixing screw holes and the screw grooves.

[0012] Adopting the above technical solution: Insert the column into the first connecting pipe. At this time, the clamping ring is clamped on the column. By rotating the clamping ring through the column, the support plate makes the ball rotate through the shaft groove. At this time, the ball moves along the guide groove. Furthermore, the clamping ring can rotate inside the rotation groove along the guide groove through the shaft groove and the ball, facilitating the rotation of the column inserted into the first connecting pipe. Rotate the hole groove on the column to one side of the fixing screw hole, and then insert the bolt through the fixing screw hole into the hole groove to fix the column.

[0013] Insert the column into the first connecting pipe, and insert the bolt through the fixing screw hole to fix the column. The three groups of reinforcing hoops arranged on the outer side wall of the first connecting pipe can increase the strength of the first connecting pipe. Clamp the bottom tension bar of the photovoltaic panel into the clamping groove, and then insert the bolts into the screw grooves opened on the second connecting pipe respectively to fix the bottom tension bar of the photovoltaic panel. Then, set the sealing cap inside the groove to protect the bolt from being corroded by seawater. The slot opened at the middle position of the second connecting pipe can be used to insert pipes. Through this pipe and plate connector, the photovoltaic panel column and the bottom tension bar of the photovoltaic panel can be connected and fixed together. BRIEF DESCRIPTION OF THE DRAWINGS
