DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides an easy-to-install waterproof photovoltaic purlin assembly, including a lower support plate 1, on which through holes 2 are evenly arranged. The through holes 2 can accelerate the separation of rainwater falling on the lower support plate 1 from the lower support plate 1, and the through holes 2 can be used to fix the photovoltaic purlin assembly to the photovoltaic bracket. The top of one end of the lower support plate 1 and the bottom of the other end are both provided with positioning grooves 6. The positioning grooves 6 can play a positioning function, which is convenient for aligning two adjacent photovoltaic purlin assemblies.

[0023] A threaded hole 11 is provided in the middle of both ends of the lower support plate 1, and a connecting plate 8 is movably connected to the top of one threaded hole 11. The middle of both ends of the connecting plate 8 is threadedly connected with a second screw 9. When the two photovoltaic purlin assemblies are aligned, the user rotates the connecting plate 8, and the second screw 9 on the other end of the connecting plate 8 can be located above the threaded hole 11 on the other photovoltaic purlin assembly, that is, the two photovoltaic purlin assemblies can be fixed together by using the connecting plate 8 and the second screw 9.

[0024] The two second screw rods 9 in the utility model are connected by a transmission structure 2, which includes a support shell 10 movably sleeved with the top of the second screw rod 9, and two sprocket wheels 16 are movably connected in the inner cavity of the support shell 10. The top of the second screw rod 9 is fixedly connected to the bottom of the sprocket wheel 16, and the two sprocket wheels 16 are connected by a chain 15. Both sides of the chain 15 are provided with a second flat pull hole 17. Through the setting of the transmission structure 2, the user pulls the chain 15 to make the two sprocket wheels 16 rotate at the same time, and the two sprocket wheels 16 rotate in the same direction. The rotating sprocket wheel 16 can drive the second screw rod 9 fixedly connected thereto to rotate, and when the second screw rod 9 rotates, the connecting plate 8 and the lower support plate 1 can be fixed together, which is convenient for the disassembly and assembly of the second screw rod 9.

[0025] A connecting vertical plate 3 is fixedly connected to the middle of the top of the lower support plate 1, and the width of the connecting plate 8 is not greater than the width of the connecting vertical plate 3, which is convenient for placing the photovoltaic module on the lower support plate 1. In some embodiments of the present application, the width of the connecting vertical plate 3 and the connecting plate 8 are the same, both of which are 45mm; in other embodiments of the present application, the width of the connecting plate 8 is 30-45mm, and the width of the connecting vertical plate 3 is 45-60mm.

[0026] The top of the connecting vertical plate 3 is connected to an upper pressure plate through a first screw 12. Drain holes are evenly arranged on the upper pressure plate, and the length of the drain holes is the same as the length of the short side of the upper pressure plate. The drain holes penetrate the upper pressure plate. Through the setting of the drain holes, the accumulated water intercepted by the upper pressure plate can be moved to the other side of the upper pressure plate. That is, when the purlin assembly is in use, the upper pressure plate can be prevented from intercepting rainwater, thereby avoiding the risk of the photovoltaic assembly being soaked in water.

[0027] The upper pressing plate includes a bottom plate 4 movably connected to the first screw rod 12, the transmission structure 1 is located in the bottom plate 4, and a cover plate 5 is fixed on the top of the bottom plate 4. The top of the cover plate 5 is inclined, and the setting of the cover plate 5 prevents rainwater from gathering on the cover plate 5.

[0028] The transmission structure 1 includes two synchronous wheels 13 movably connected to the base plate 4. The two synchronous wheels 13 are connected through a synchronous belt 14. A flat pulling hole 7 is provided in the middle of the outer side of the synchronous belt 14. The synchronous wheel 13 is fixedly connected to the top of the first screw rod 12. Through the setting of the transmission structure 1, the movement of the synchronous belt 14 can make the two first screw rods 12 rotate synchronously, which is convenient for the disassembly and assembly of the upper pressure plate.

[0029] From the above description, it can be seen that the utility model changes the force for twisting the first screw 12 or the second screw 9 into a force for pulling the synchronous belt 14 or the chain 15 to translate, so that the first screw 12 and the second screw 9 can be quickly disassembled and assembled, thereby improving the disassembly and assembly efficiency of the photovoltaic purlin assembly.

[0030] In some embodiments of the present application, the material of the photovoltaic purlin assembly is aluminum alloy or stainless steel, and the surface of the photovoltaic purlin assembly is coated with a waterproof coating.

[0031] To sum up: when using the easy-to-install waterproof photovoltaic purlin assembly, the user fixes the lower support plate 1 on the photovoltaic bracket 19, places one end of the photovoltaic assembly 18 on the lower support plate 1, and drives the synchronous belt 14 to move through the flat pull hole 7. During the movement of the synchronous belt 14, the synchronous wheel 13 is driven to rotate, and the synchronous wheel 13 drives the first screw 12 fixedly connected thereto to rotate until the upper pressure plate is tightly fitted with the top of the photovoltaic assembly 18, and the photovoltaic assembly and the photovoltaic purlin assembly are fixed together.

[0032] When two photovoltaic purlin assemblies need to be connected together, the user aligns the positioning grooves 6 on the two photovoltaic purlin assemblies, rotates the connecting plate 8, and connects the connecting plate 8 to the threaded holes 11 on the two photovoltaic purlin assemblies. The user drives the chain 15 to move through the second flat pull hole 17. During the movement of the chain 15, the sprocket 16 is driven to rotate. The sprocket 16 drives the second screw 9 to rotate. The second screw 9 and the connecting plate 8 can be used to fix the two photovoltaic purlin assemblies together.

[0033] When the photovoltaic purlin assembly is in use, rainwater intercepted by the upper pressure plate is drained away through the drainage holes to prevent rainwater from accumulating on the photovoltaic assembly. In addition, by setting the positioning grooves, rainwater on the lower support plate 1 can be drained away to prevent rainwater from accumulating on the photovoltaic purlin assembly.

[0034] The standard parts used in the utility model can be purchased from the market, and the special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art. The machinery, parts and equipment all adopt the conventional models in the prior art and will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and modifications can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
