Description

Technical Field

[0001] The utility model relates to the technical field of damper systems, especially a symmetric single-axis damper system. Background Art

[0002] As shown in the traditional damper system Figure 3 When the photovoltaic main shaft 101 rotates, it drives the upper connecting piece 102, causing the dampers 103 on both sides of the main shaft to contract and stretch, so as to achieve the purpose of shock absorption and stability. When the damper acts under force, since the force application directions of the dampers on the lower connecting piece 105 cross each other, the lower connecting piece will be subjected to a large torsional force. At the same time, the lateral force acting on the lower connecting piece is not on the centroid axis of the column 104. This eccentric force will cause the column to twist, and the force and moment transmitted by the lower connecting piece are concentrated on the web of the column 104, which is not conducive to the stability of the column;

[0003] In addition, to ensure that the damper does not collide with other components, the length of the lower connecting piece needs to be set longer, and the lower connecting piece also needs to be welded with a bottom plate and stiffening plates to improve strength, increasing the structural cost;

[0004] In view of the above defects, this application is proposed. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a symmetric single-axis damper system, which is used to solve the problem of the torsional force generated by the damper system on the column in the prior art solution, optimize the force application mode, ensure the stability of the column, and reduce costs.

[0006] To solve the above problems, the utility model provides a symmetric single-axis damper system, including an upper connection assembly, dampers, and a lower support assembly. The upper connection assembly includes a main shaft connecting piece and a swing arm connected to each other. The lower support assembly includes a damper connection part and a column connection part. At least two groups of dampers are provided. The two ends of the damper are respectively connected to the swing arm and the damper connection part. The two groups of dampers are symmetrically arranged on both sides of the column connection part, and the force application directions of the two groups of dampers on the lower support assembly are parallel, so that the force transmitted by the damper to the connecting piece coincides with the centroid axis of the column, so as to achieve the purpose of eliminating the torsional force. After the torsional force is eliminated, the stability of the column is higher.

[0007] According to an embodiment of the utility model, the main shaft connecting piece is a hoop.

[0008] According to an embodiment of the utility model, the number of the upper connection assemblies is the same as the number of the dampers, that is, the number of the hoops and the swing arms is the same as the number of the dampers.

[0009] Optionally, in other embodiments, the number of the swing arms can be less than the number of the dampers. For example, several dampers are installed on the same swing arm.

[0010] According to an embodiment of the present utility model, the symmetric single-axis damper system further includes a column, and the lower support assembly is connected to the column through a column connection part.

[0011] According to an embodiment of the present utility model, the lower support assembly is connected to the flange position of the column, changing the force application point of the column from the web center in the traditional solution to the flange, reducing the moment in the strong axis direction of the damper. Under the same torque, the force transmitted by the damper to the strong axis direction of the column is also correspondingly reduced.

[0012] According to an embodiment of the present utility model, the lower support assembly further includes a lower support backing plate and lower support ear plates. The column connection part and the lower support ear plates are both arranged on the lower support backing plate. A plurality of groups of lower support ear plates are provided, and a damper connection part is formed between adjacent lower support ear plates.

[0013] By providing the lower support backing plate, replacing the square tube with a plate reduces the cost.

[0014] Optionally, the number of the lower support ear plates is twice the number of dampers, or a plurality of dampers can be connected between two lower support ear plates.

[0015] According to an embodiment of the present utility model, the lower support backing plate has an L-shaped structure, and the lower support ear plates are connected to both wall surfaces of the L-shaped structure.

[0016] Preferably, the lower support backing plate is an overall L-shaped plate, so that the forming process does not require welding, shortening the component manufacturing time. Moreover, the L-shaped lower support backing plate has simple stress, reducing the required materials of the plate and lowering the cost.

[0017] According to an embodiment of the present utility model, the column connection part includes a plurality of bolt holes arranged on the lower support backing plate, and the lower support backing plate and the column are connected through bolt assemblies.

[0018] According to an embodiment of the present utility model, the symmetric single-axis damper system further includes a main shaft, and the hoop is connected to the main shaft.

[0019] The beneficial effects of the present utility model are as follows: by symmetrically arranging the dampers on both sides of the column and making the force application directions of the two groups of dampers on the lower support assembly parallel, the torsional forces generated by the dampers on the column are offset by the symmetric structure design, making the force transmitted by the damper to the lower support assembly coincide with the centroid axis of the column, so as to achieve the purpose of eliminating the torsional force. After the torsional force is eliminated, the stability of the column is higher; in this solution, the installation method of the damper does not require increasing the length of the lower support backing plate to avoid collision, and since the force on the lower support backing plate is reduced, there is no need for a bottom plate and stiffeners to improve the strength. The forming is simple, reducing the required materials of the plate and lowering the cost of the structure. Description of the Drawings

[0024] The following description is intended only to disclose the present invention and to enable those skilled in the art to implement the present invention. The embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0025] Symmetrical uniaxial damper systems are generally used in the photovoltaic field, such as Figure 1 , including an upper connecting assembly, two dampers 4, and a lower support assembly 10.

[0026] The upper connecting assembly is used to connect the main shaft 2 and the damper 4, the lower support assembly 10 is used to connect the column 5 and the damper 4, and the main shaft 2 is used to connect the photovoltaic panel.

[0027] The upper connecting assembly includes a main shaft connecting part and a swing arm 3 connected to each other, wherein the main shaft connecting part is a clamp 1, the clamp 1 is connected to the main shaft 2, and the swing arm 3 is hinged to the upper end of the damper 4 through a pin body and an upper retaining ring 9. Two groups of upper connecting assemblies are provided.

[0028] The lower support assembly 10 includes a lower support pad 6, a lower support ear plate 7, a damper connection part and a column connection part 11. The column connection part 11 and the lower support ear plate 7 are both arranged on the lower support pad 6. Four groups of lower support ear plates 7 are arranged symmetrically. A damper connection part is formed between two groups of lower support ear plates 7. The lower support pad 6 is an L-shaped plate as a whole, so that no welding is required in the forming process, which shortens the component manufacturing time. The L-shaped lower support pad 6 is simply stressed, which reduces the material required for the plate and reduces the cost. The lower support ear plate 7 is connected to both wall surfaces of the L-shaped structure to improve the support stability. The lower support ear plate 7 is hinged to the lower end of the damper 4 through a pin body and a lower retaining ring 8.

[0029] like Figure 2 The column connecting portion 11 includes four bolt holes provided on the lower support plate 6 , and the lower support plate 6 is connected to the column 5 via a bolt assembly 12 .

[0030] The column 5 is generally an H-shaped column. The lower support assembly 10 is connected to the flange position of the column 5, changing the force application point of the column 5 from the web center in the traditional solution to the flange. The moment in the strong axis direction of the damper decreases, and under the same torque, the force transmitted by the damper to the strong axis direction of the column also decreases accordingly.

[0031] Two groups of dampers 4 are symmetrically arranged on both sides of the column connection part 11 and the column 5, and the force application directions of the two groups of dampers 4 on the lower support assembly 10 are parallel. The symmetrical structure design cancels out the torsional forces generated by the dampers on the column, making the force transmitted by the dampers to the connecting piece coincide with the centroid axis of the column to achieve the purpose of eliminating the torsional force. After the torsional force is eliminated, the stability of the column is higher.

[0032] Under the ideal state adopted by the present invention, when the photovoltaic main shaft rotates, the force and moment transmitted by the damper to the column both act on the strong axis of the column, and the stability is better.

[0033] Those skilled in the art should understand that the above description and the embodiments of the present invention shown in the drawings are only examples and do not limit the present invention. The object of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been shown and described in the embodiments. Without departing from the said principle, the embodiments of the present invention can have any deformation and modification.
