Description

Technical Field

[0001] The utility model relates to a novel cross coupling, belonging to the technical field of speed reducers. Background Art

[0002] At present, traditional tracking photovoltaic power generation is adopted in mountainous and hilly areas, which has high requirements for land flatness and infrastructure. Appropriate leveling is required, and when driving piles, the support platforms should be as straight as possible to facilitate the installation of the main beam. Therefore, in similar geographical environments, fixed photovoltaic power generation is basically adopted and scattered layout is carried out in suitable sites. The infrastructure cost is relatively high, so there are disadvantages such as small installed capacity, low efficiency, and short sunshine time. Summary of the Invention

[0003] The purpose of the utility model is to overcome the above deficiencies and provide a novel cross coupling, which has the advantages of large installed capacity, high power generation efficiency, long sunshine time, etc.

[0004] The purpose of the utility model is realized as follows:

[0005] A novel cross coupling includes a cross joint. The vertical shaft and the horizontal shaft of the cross joint are perpendicular to each other. A connecting plate is respectively arranged at the upper and lower ends of the vertical shaft, and a connecting plate is also respectively arranged on the front and rear sides of the horizontal shaft. The vertical shaft is connected with the connecting plates at the upper and lower ends by bolts, and the horizontal shaft is connected with the connecting plates on the front and rear sides by bolts. The connecting plates are U-shaped. Among them, the two connecting plates on the vertical shaft are arranged relatively up and down, and the U-shaped notch between the upper and lower two connecting plates catches the left main beam; the two connecting plates on the horizontal shaft are arranged relatively front and rear, and the U-shaped notch between the front and rear two connecting plates catches the right main beam. There are gaps between both the left main beam and the right main beam and the connecting plates. The connecting plates are fixed to the main beam, and fine adjustments in the front and rear, left and right, and up and down directions can be made. After selecting the position, the connecting plates and the main beam are fixed with fasteners.

[0006] Each connecting plate is provided with threaded holes on its three surfaces, and fasteners pass through the threaded holes.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] This novel cross coupling is provided with a cross joint, and the two adjacent main beams are respectively fixed by the two perpendicular shafts on the cross joint with connecting plates, and the relative positions between the two main beams can be slightly adjusted. In this way, a certain deviation in the up and down and left and right directions can be tolerated between adjacent platforms, so that the site does not need to be leveled and accurately measured, increasing the installed capacity, improving the installation efficiency, extending the sunshine time, and thus greatly reducing the infrastructure cost. In addition, tracking photovoltaic power generation can be used in hilly areas and other regions, improving the applicable range of photovoltaic modules. Description of the Drawings

The vertical shaft 2 is connected to the connecting plates 4 at the upper and lower ends through bolts 5, and the horizontal shaft 3 is connected to the connecting plates 4 on the front and rear sides through bolts 5.

[0013] The connecting plate 4 is U-shaped, and the notch of the U-shape of the connecting plate 4 is used to clamp the main beam of the photovoltaic module. Among them, the two connecting plates 4 on the vertical shaft 2 are arranged oppositely up and down, and the U-shaped notch between the upper and lower two connecting plates 4 is used to clamp the left main beam 6; the two connecting plates 4 on the horizontal shaft 3 are arranged oppositely front and rear, and the U-shaped notch between the front and rear two connecting plates 4 is used to clamp the right main beam 7.
