Description

Technical Field

[0001] This utility model relates to the field of pipe fitting connection device technology, and in particular to a pipe head connector. Background Technology

[0002] Photovoltaic power generation is becoming increasingly popular, and onshore photovoltaic power generation is already quite mature, but it occupies a lot of land space. Offshore photovoltaic power generation can effectively avoid the limitations of land space, utilizing the vast ocean area for deployment, and also avoiding problems such as building obstruction and terrain influences. At the same time, seawater can play a role in heat dissipation, improving the power generation efficiency of photovoltaic panels.

[0003] Traditional floating photovoltaic equipment requires the installation of an external wave barrier and connecting pipes to provide buoyancy. The installation of the pipes and wave barrier requires multiple fittings to be connected and then assembled to form the wave barrier and connecting pipes. The traditional method of connecting fittings is mostly to use clamps and flanges. This method requires the pipe fitting interfaces to be connected, and if the pipe length is insufficient, it cannot effectively and stably connect.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] According to the pipe connector of this utility model, a connecting pipe is fixedly provided on the outside of the mating pipe head, and a sealing part is provided inside the mating pipe head, which seals the inside of the connecting pipe to form a hollow area.

[0009] According to the pipe connector of this utility model, the snap-fit ​​parts inside the ring sleeve are symmetrically distributed about the central cross-section of the ring sleeve, and the size of the snap-fit ​​groove inside the different snap-fit ​​parts is different.

[0011] According to the pipe connector of this utility model, a sealing ring surface that fits with the sealing part is provided between two adjacent snap-fit ​​parts.

[0012] This utility model provides a pipe head connector, comprising: two opposing rings for clamping and fixing the pipe head, thereby ensuring the connection and fixation of the connecting pipe; each ring has several locking portions on its inner wall, each locking portion including several locking ring grooves distributed along the axis of the ring, ensuring that the locking portion has a certain width, so that when fixing the mating pipe head, the mating pipe head can move within the width of the corresponding locking portion, achieving the docking effect when the distance of the mating pipe head changes; the mating pipe head has an annular protrusion on its outer ring corresponding to the locking ring groove, the annular protrusion engaging with the annular groove, and the mating pipe head locking into the inside of the locking ring groove, thereby restricting the axial movement of the pipe head, realizing the installation and fixation of pipe heads at different distances.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0018] See Figures 1-3 This utility model provides a pipe head connector, which includes two opposing rings 6. The two rings 6 are used to fix and clamp the pipe head, thereby ensuring the connection and fixation of the connecting pipe 5. The inner wall of each ring 6 is provided with several snap-fit ​​parts, and each snap-fit ​​part includes several snap-fit ​​ring grooves. The snap-fit ​​ring grooves are distributed along the axis of the ring 6 to ensure that the snap-fit ​​parts have a certain width. So when fixing the mating pipe head, the mating pipe head can move within the width of the corresponding snap-fit ​​part, achieving the docking effect when the distance of the mating pipe head changes. The mating pipe head has an outer ring with an annular protrusion corresponding to the snap-fit ​​ring groove. The annular protrusion engages with the annular groove, and the mating pipe head snaps into the inside of the snap-fit ​​ring groove, thereby restricting the axial movement of the pipe head and realizing the installation and fixation of pipe heads at different distances.

[0019] Preferably, the outer wall of the ring sleeve 6 of this utility model is provided with an installation protrusion 7, which cooperates with the snap ring groove to ensure that the fitting tube head is snapped into the inside of the snap ring groove. The installation protrusion 7 is provided with a plurality of tube head pressing holes 62, and a fixing bolt is inserted into the inside of the tube head pressing holes 62. A connecting tube 5 is fixedly provided on the outer side of the fitting tube head, and a sealing part 3 is provided inside the fitting tube head. The sealing part 3 seals the inside of the connecting tube 5 to form a hollow area, ensuring that the connecting tube 5 can float on the seawater and complete the support and protection of the photovoltaic equipment.

[0020] In addition, the snap-fit ​​parts inside the ring sleeve 6 of this utility model are symmetrically distributed about the center cross-section of the ring sleeve 6, ensuring that the snap-fit ​​parts at both ends of the ring sleeve 6 can adapt to the same mating pipe head, preventing the phenomenon that the two ends cannot be fixed synchronously. The size of the snap-fit ​​ring groove inside the different snap-fit ​​parts is different.

[0021] Furthermore, the present invention has several mounting protrusions 7 to ensure that the mounting protrusions 7 correspond to multiple snap-fit ​​ring grooves, ensuring the reliability of the mating pipe head installation. The end of the mating pipe head and the tail of the mounting protrusions 7 are provided with sealing parts that fit against the inner wall of the ring sleeve 6. A sealing ring surface that fits against the sealing parts is provided between two adjacent snap-fit ​​parts, so that the mating pipe head can fit tightly into the inside of the ring sleeve 6, preventing the ring sleeve 6 from vibrating and affecting the service life of the ring sleeve 6.

[0022] In use, the corresponding mating pipe head is fixed to the connecting pipe 5, or the connecting pipe 5 and the mating pipe head are directly integrated into one structure. As long as the distance between the pipe heads is within the area of ​​the corresponding snap-fit ​​part, the two rings 6 are directly snapped onto the corresponding mating pipe head. Then, the two rings 6 are fixed using fastening bolts, thus completing the fixing of the mating pipe head. In this embodiment, as shown... Figure 3As shown, two types of snap-fit ​​parts are provided. The first snap-fit ​​part 61 is located on the inner side, and the second snap-fit ​​part 63 is located on the outer side. Moreover, the positions of the two snap-fit ​​parts can be adapted to ensure that they can be used to fix the fitting pipe head at different distances.

[0023] In summary, this utility model provides a pipe head connector, comprising: two opposing rings for clamping and fixing the pipe head, thereby ensuring the connection and fixation of the connecting pipe; each ring has several snap-fit ​​portions on its inner wall, each snap-fit ​​portion including several snap-fit ​​grooves distributed along the axis of the ring to ensure that the snap-fit ​​portion has a certain width, so that when fixing the mating pipe head, the mating pipe head can move within the width of the corresponding snap-fit ​​portion, achieving the docking effect when the distance of the mating pipe head changes; the mating pipe head has an annular protrusion on its outer ring corresponding to the snap-fit ​​groove, the annular protrusion engaging with the annular groove, and the mating pipe head snapping into the inside of the snap-fit ​​groove, thereby restricting the axial movement of the pipe head and enabling the installation and fixation of pipe heads at different distances. In summary, the technical effect of this utility model is to provide a connector that adapts to pipe heads of different lengths and distances, ensuring that two pipe heads can be docked and fixed when the distance of the pipe heads changes, achieving adaptability to pipe head docking.
