[0001] The present invention relates to the field of photovoltaic technology, and in particular to a shaft rotator and a photovoltaic bracket having the shaft rotator. Background Art

[0002] In traditional photovoltaic power station projects, in order to improve the return on investment, many projects adopt the mode of combining photovoltaic with other industries, such as photovoltaic with agriculture and fishery. In order to make full use of the existing land resources, planting and breeding are carried out under the power station. In these projects, it is often necessary to build adjustable photovoltaic brackets very high, which makes it difficult to adjust the angle of the bracket. For example, forest photovoltaic complementary projects require the components to be more than 3.5 meters above the ground, and some fish photovoltaic complementary projects or agricultural photovoltaic complementary projects require the components to be more than 2.5 meters above the ground. It is difficult for people to operate on the ground, so it is difficult to adjust the angle of the bracket.

[0003] In the process of implementing the traditional technology, the applicant found that when adjusting the angle of the high bracket, the operator usually needs to climb to the adjustment shaft with the help of equipment such as a ladder, which is time-consuming, labor-intensive and inefficient. For example, the fishing boats used for maintenance in the fish-light complementary project are generally small and shake a lot. It is difficult to set up a ladder on the boat. Climbing to the adjustable bracket to adjust the height of the shaft is a high-altitude operation, and the safety is also poor. Summary of the invention

[0033] Please refer to Figure 1 to Figure 2 The present application provides a shaft rotator 1, comprising a telescopic rod 10 and a transmission assembly.

[0034] One end of the telescopic rod 10 is supported on the ground, and the other end is fixed with a transmission assembly, wherein the transmission assembly includes a sprocket 11 and a chain 13, wherein the sprocket 11 is placed in a housing 12, the top of the telescopic rod 10 is fixedly connected to the housing 12, one end of the chain 13 is wound around the sprocket 11, the axis of the sprocket 11 is fixedly connected with a transmission shaft 14, and the transmission shaft 14 is provided with a first transmission part 15, and the sprocket 11 can be driven to rotate by manually pulling the chain 13.

[0035] The transmission assembly also includes a transmission sleeve 16 , one end of which is provided with a second transmission part 17 that can cooperate with the first transmission part 15 to transmit torque to the transmission sleeve 16 , and the other end is used for fixed connection with the rotating shaft 19 .

[0036] See also Figures 2 to 4 In this embodiment, the first transmission part 15 includes a plurality of first stoppers 151, which extend radially outward from the surface of the transmission shaft 14; the second transmission part 17 includes a plurality of second stoppers 171, which extend radially inward from the inner surface of the transmission sleeve 16, and the second stoppers 171 can rotate to transmit torque under the action of the first stoppers 151. According to actual needs, the first transmission part 15 and the second transmission part 17 can also have various matching modes, such as snap fit, spline fit, etc.

[0037] When the shaft rotator 1 of this embodiment is used to adjust the shaft 19, the height of the telescopic rod 10 is first adjusted according to the height of the shaft 19, so that the axis of the sprocket 11, the axis of the transmission shaft 14, the axis of the transmission sleeve 16 and the axis of the shaft 19 are located on the same horizontal line. The transmission shaft 14 is inserted into the transmission sleeve 16, so that each first stopper 151 of the first transmission part 15 is against each second stopper 171 of the second transmission part 17. At this time, the staff pulls the chain 13 below the shaft rotator 1, which can provide a torque for the sprocket 11 to rotate around its axis, and the transmission shaft 14 will also drive the first stopper 151 to rotate, and the first stopper 151 will act on the second stopper 171 to transmit the torque to the transmission sleeve 16, and the transmission sleeve 16 finally drives the shaft 19 to rotate.

[0038] The shaft rotator 1 has a detachably connected transmission shaft 14 and a transmission sleeve 16. The transmission sleeve 16 is installed at one end of the shaft 19 before the transmission shaft 14 is connected, so that different types of shafts 19 can be matched. At the same time, with the help of the height adjustment of the telescopic rod 10, the shafts 19 at different heights can also be matched. During operation, the staff does not need to climb to a high place to work, and the risk is low.

[0039] According to some embodiments of the present invention, the second stopper 171 can be replaced by a plurality of grooves, which are arranged inside the transmission sleeve 16 and can cooperate with the first stopper 151 to transmit torque. In this case, the first stopper 151 and the groove form a spline fit, which facilitates the docking of the transmission shaft 14 and the transmission sleeve 16.

[0040] According to some embodiments of the present invention, a bell-mouth member 18 is provided at one end of the transmission sleeve 16 close to the second transmission part 17. The bell-mouth member 18 has a large opening, so that the transmission shaft 14 can be quickly and accurately inserted into the transmission sleeve 16 when the worker lifts the sprocket 11, which facilitates the connection between the transmission shaft 14 and the transmission sleeve 16 in the air and improves work efficiency.

[0041] See also Figure 4 The present application also provides a photovoltaic support 2, including a column 20 and a crossbeam 21, wherein the crossbeam 21 is rotatably fixed on the column 20, wherein a scissor jack 22 is movably connected between the column 20 and the crossbeam 21, wherein an upper hinge 211 of the scissor jack 22 is connected to the crossbeam 21 via a pin, and a lower hinge 201 is connected to the column 20 via a pin. According to actual needs, the pin can also be replaced by other rotatable connectors. The scissor jack 22 is controlled by a rotating shaft 19, and one end of the rotating shaft 19 is connected to the rotating shaft rotator 1 as described above, wherein the transmission sleeve 16 of the rotating shaft rotator 1 is provided with a bell-mouth member 18 at one end close to the second transmission part 17 to facilitate the docking of the transmission shaft 14 and the transmission sleeve 16.

[0042] The photovoltaic panel is installed on the crossbeam 21 of the photovoltaic bracket 2. The staff standing on the ground can extend the transmission assembly to the same height as the shaft 19 through the telescopic rod 10, and then insert the transmission shaft 14 into the transmission shaft sleeve 16 to complete the matching of the shaft rotator 1 and the shaft 19. At this time, pulling the chain 13 can transmit the torque to the shaft 19, thereby driving the scissor jack 22 to open and close, and the distance between the upper hinge point 211 and the lower hinge point 201 changes accordingly, thereby adjusting the inclination angle of the photovoltaic panel.

[0043] See also Figure 5 One end of the telescopic rod 10 in this embodiment is placed on the ground, so when pulling the chain 13, the telescopic rod 10 can be used as a supporting point to reduce the shaking of the transmission component; at the same time, the staff can complete the adjustment of the inclination angle of the photovoltaic bracket by standing on the ground, which is easy to operate and highly safe.

[0044] According to some embodiments of the present invention, the telescopic rod 10 includes a telescopic portion 101 and a triangular support portion 102 provided at the lower end of the telescopic portion 101, and the triangular support portion 102 is supported on the ground. The use of triangular support can further reduce the shaking of the transmission assembly during operation and improve stability.

[0045] According to some embodiments of the present invention, one end of the rotating shaft 19 away from the rotating shaft rotator 1 can extend and be connected in series with multiple scissor jacks 22, so that the inclination angles of multiple photovoltaic supports can be adjusted simultaneously when operating the rotating shaft rotator 1, further improving work efficiency.

[0046] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
