Description

Technical Field

[0001] The utility model belongs to the field of photovoltaic power generation auxiliary components, and particularly relates to a shock-absorbing structure for a photovoltaic bracket. Background Technique

[0002] During the use of a photovoltaic panel, it will be affected by wind force and ground vibration. Therefore, the installation of the photovoltaic panel has certain requirements for the rigidity and shock-absorbing ability of the photovoltaic bracket. In actual situations, the main factor that affects the photovoltaic panel for the longest time and the highest frequency is wind force. Due to the rigidity of the photovoltaic bracket itself, when the photovoltaic panel is installed on the photovoltaic bracket, only when affected by a large wind force, will it be difficult for the photovoltaic bracket to support, resulting in a large amplitude of vibration. Under normal circumstances, the photovoltaic bracket is mainly affected by medium and small wind forces.

[0003] Existing photovoltaic brackets mainly adopt rigid connections, and shock absorption relies on the elastic and deformation properties of the bracket itself, which has obvious deficiencies in shock absorption performance. When affected by medium and small wind forces, the photovoltaic bracket will generate small-amplitude vibrations with a high frequency. This kind of vibration will affect the installation stability of the photovoltaic panel and the photovoltaic bracket, and it is difficult to detect. During the long-term use of the photovoltaic bracket, problems such as loosening will occur. At the same time, the existing photovoltaic bracket and the photovoltaic panel are mainly connected and fixed through several points. During long-term use, this kind of vibration will cause excessive stress on these points, resulting in damage to the photovoltaic panel. Content of the Utility Model

[0004] To overcome the deficiencies and existing problems of the prior art and improve the shock-absorbing ability of the photovoltaic bracket for small-amplitude high-frequency vibrations, the utility model provides a shock-absorbing structure for a photovoltaic bracket.

[0005] The utility model is realized through the following technical solutions:

[0006] A shock-absorbing structure for a photovoltaic bracket includes a conduction seat and a conduction rod. An activity cavity is provided in the conduction seat, a fixed groove is provided at the bottom of the activity cavity, a shock-absorbing ball is provided in the fixed groove, the lower end of the conduction rod is inserted into the activity cavity and abuts against the top surface of the shock-absorbing ball. A limiting cover connected to the top of the conduction seat is sleeved on the conduction rod. A limiting ring cooperating with the limiting cover is provided on the circumference of the bottom end of the conduction rod. A shock-absorbing ring is also sleeved on the conduction rod. The upper end of the shock-absorbing ring is located between the limiting cover and the conduction rod, and the lower end of the shock-absorbing ring is located between the limiting ring and the wall of the activity cavity. Both the shock-absorbing ring and the shock-absorbing ball are made of rubber material. A connecting piece for connecting the photovoltaic bracket is provided at the top of the conduction rod, and a connecting portion for connecting the photovoltaic bracket is provided at the bottom of the conduction seat.

[0007] The limiting cover is threadedly connected to the top end of the conduction seat, and the outer circle of the limiting cover is in the shape of a hexagonal nut.

[0008] The top of the conduction rod is provided with an internal hexagonal hole, and the connecting piece is provided with a through hole corresponding to the internal hexagonal hole.

[0009] The connecting piece includes a connecting seat, the connecting seat is threadedly connected to the top of the conduction rod, the top of the connecting seat is provided with a first rotating part, and the top of the first rotating part is provided with a first screw part.

[0010] The connecting part includes a second rotating part, and the bottom of the second rotating part is provided with a second screw part.

[0011] Both the first rotating part and the second rotating part are hexagonal in shape, and both the first rotating part and the second rotating part are provided with radial through channels.

[0012] Both the first rotating part and the second rotating part are respectively provided with three through channels, and each through channel penetrates from one side surface of the first rotating part and the second rotating part to the opposite side surface.

[0013] The utility model realizes the shock absorption function by using the shock absorption balls and shock absorption rings made of rubber material. Compared with the traditional spring and elastic sheet structures, the shock absorption balls made of rubber material are not easy to generate excessive vibration and have good shock filtering ability. At the same time, the utility model utilizes the deformation performance of the rubber material to enable the conduction rod and the conduction seat to have a space for relative displacement when connected, and realizes multi-directional shock filtering by means of displacement extrusion of the shock absorption balls and shock absorption rings. In the utility model, the limiting cover is connected to the top of the conduction seat, and through the cooperation of the limiting ring and the limiting cover, it is possible to prevent the conduction rod from being disengaged due to excessive movement amplitude.

Detailed Embodiment

[0018] For the convenience of understanding by those skilled in the art, the following further describes the utility model in detail with reference to the drawings and specific embodiments.

[0019] As Figure 1 , 2 shown, a shock-absorbing structure for a photovoltaic support includes a conduction rod 100 and a conduction seat 200. Both the conduction rod 100 and the conduction seat 200 are used to conduct the vibration brought by the support. An activity cavity 210 is provided in the conduction seat 200. A fixing groove 220 is provided at the bottom of the activity cavity 210. A shock-absorbing ball 230 is provided in the fixing groove 220. The shock-absorbing ball 230 is used to provide shock-absorbing performance. The fixing groove 220 can prevent the shock-absorbing ball 230 from loosening and displacing. The lower end of the conduction rod 100 is inserted into the activity cavity 210 and abuts against the top surface of the shock-absorbing ball 230. The shock-absorbing ball 230 is made of rubber material. When the conduction rod 100 contacts the shock-absorbing ball 230, it can rely on the elasticity of the shock-absorbing ball 230 for shock absorption, and at the same time, a certain activity range can be obtained by using the deformation ability of the shock-absorbing ball 230. A limit cover 110 is sleeved on the conduction rod 100. The limit cover 110 is threadedly connected to the top end of the conduction seat 200. The outer ring of the limit cover 110 is in the shape of a hexagonal nut. The hexagonal nut-shaped structure makes the limit cover 110 easier to screw during installation, and it is convenient for disassembly and assembly.

[0020] As Figure 2 , 3 shown, a limit ring 120 cooperating with the limit cover 110 is provided at the bottom end of the conduction rod 100. The inner diameter of the sleeve hole of the limit cover 110 is smaller than the outer diameter of the limit ring 120. When the limit cover 110 is connected to the conduction seat 200, the conduction rod 100 will generate a certain activity in the activity cavity 210 after being stressed. The cooperation of the limit ring 120 and the limit cover 110 limits the activity range of the conduction rod 100 in the vertical direction, so that the bottom end of the conduction rod 100 is always in the activity cavity 210, preventing the conduction rod 100 from being disengaged due to excessive activity. A shock-absorbing ring 130 made of rubber material is also sleeved on the conduction rod 100. The upper end of the shock-absorbing ring 130 is located between the limit cover 110 and the conduction rod 100, and the lower end of the shock-absorbing ring 130 is located between the limit ring 120 and the wall of the activity cavity 210. The vibration generated by the support will be conducted to the conduction seat 200 and the conduction rod 100. The conduction rod 100 and the conduction seat 200 are stressed to generate relative displacement and squeeze the shock-absorbing ball 230 and the shock-absorbing ring 130, realizing multi-directional shock filtration. The automatic reset can be realized by using the elasticity and deformation performance of the shock-absorbing ball 230 and the shock-absorbing ring 130.

[0021] As Figure 2 , 3As shown in the figure, a connecting member 140 is provided at the top of the conduction rod 100. The connecting member 140 is used to mount the conduction rod 100 on a photovoltaic bracket. The connecting member 140 includes a connecting seat 141. The connecting seat 141 is threadedly connected to the top of the conduction rod 100 to conduct the vibration generated by the bracket to the conduction rod 100. An internal hexagonal hole 101 is provided at the top of the conduction rod 100, and a through hole 143 corresponding to the internal hexagonal hole 101 is provided on the connecting member 140. When the conduction column is to be connected to the connecting seat 141, an internal hexagonal tool can be used to pass through the through hole 143 to screw and fix the conduction column on the connecting seat 141. A first rotating part 142 is provided at the top of the connecting seat 141, and a first screw part 144 is provided at the top of the first rotating part 142. The first rotating part 142 facilitates the operator to drive the first screw part 144 by a rotating force, so that the first screw part 144 is threadedly connected to the photovoltaic bracket.

[0022] As Figure 2 , 3 shown in the figure, a connecting part 240 is provided at the bottom of the conduction seat 200. The connecting part 240 is used to mount the conduction seat 200 on a photovoltaic bracket. The connecting part 240 includes a second rotating part 241. A second screw part 242 is provided at the bottom of the second rotating part 241. The second rotating part 241 facilitates the operator to drive the second screw part 242 by a rotating force, so that the second screw part 242 is threadedly connected to the photovoltaic bracket, and then the conduction seat 200 is mounted on the bracket. Both the first rotating part 142 and the second rotating part 241 are hexagonal in shape and can be screwed by tools such as a wrench, which is convenient for disassembly and assembly. Radial through channels 300 are provided on both the first rotating part 142 and the second rotating part 241. The operator can pass a support rod through the through channel 300 to screw the first rotating part 142 or the second rotating part 241. Three through channels 300 are respectively provided on both the first rotating part 142 and the second rotating part 241. Each through channel 300 penetrates from one side surface of the first rotating part 142 and the second rotating part 241 to the opposite side surface. The multiple through channels 300 facilitate the operator to pass the support rod through the through channel 300 from multiple directions, which is convenient for operation.

[0023] Installation process: First, the limit cover 110 and the shock-absorbing ring 130 are sleeved on the conduction rod 100 through the upper end of the conduction rod 100. Then, the conduction rod 100 is connected to the connecting seat 141, and the conduction rod 100 is tightened by an internal hexagonal tool. Finally, the connecting member 140 can be connected to the bracket. After the conduction rod 100 is installed, the shock-absorbing ball 230 is placed in the fixing groove 220, and the limiting ring 120 part on the conduction rod 100 is extended into the movable cavity 210. Then, the limit cover 110 is screwed and fixed on the conduction seat 200 to prevent the conduction rod 100 from loosening. Finally, the connecting part 240 is connected to the bracket, and the installation is completed.

[0024] The above embodiments are the preferred implementation manners of the present utility model, and are not intended to limit the present utility model. Without departing from the inventive concept of the present utility model, any obvious substitution is within the protection scope of the present utility model.
