Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support systems, specifically a terrain-adaptive mountain photovoltaic support system foundation adjustment device. Background Technology

[0002] Mountainous regions, with their abundant solar resources and vast unused land, have become important sites for photovoltaic power plant construction. However, the complex terrain of mountainous areas, characterized by large undulations, irregular slopes, and diverse geological conditions, presents numerous challenges to the installation and stable operation of photovoltaic support systems. Traditional support systems generally use a slider-groove connection device to install and position adjacent support systems. Due to the frequent winds and sandstorms in mountainous areas, mud and sand can easily mix in, increasing the resistance of the slider movement and even causing jamming, directly affecting the installation of photovoltaic support systems. Utility Model Content

[0003] To address the problem of increased resistance caused by the mixing of mud and sand during the movement of the slider-groove structure in the aforementioned technologies, this invention provides an adaptive terrain-adaptive mountain photovoltaic support foundation adjustment device.

[0004] The technical solution of this utility model is as follows: An adaptive terrain-adaptive photovoltaic (PV) support foundation adjustment device for mountainous areas, comprising a PV support with a pre-set track and PV panels mounted above the PV support. The photovoltaic bracket has a movable outer shell inside its track. The movable outer shell has countersunk holes at both ends facing the side wall of the track. The countersunk holes contain movable ball bearings that cannot be disengaged from the countersunk holes and extend out of the movable outer shell. The movable outer shell also has a fixing bolt extending out of the photovoltaic bracket track at the center of its surface. The photovoltaic support includes horizontal supports and vertical supports arranged perpendicularly to each other. A first reinforcing plate is provided at the connection between the horizontal supports and the vertical supports. The first reinforcing plate is connected to the fixing bolts extending from the vertical supports and the horizontal supports. A second reinforcing plate is provided at the connection between the longitudinal support and the photovoltaic panel, and the second reinforcing plate is connected to the fixing bolts extending from the longitudinal support.

[0005] Furthermore, in the adaptive terrain mountain photovoltaic support foundation adjustment device described above, the length of the moving ball extending out of the moving shell is less than the radius of the moving ball.

[0006] The method of providing elastic cushioning for the moving ball is as follows: an elastic element is provided between the moving ball and the moving housing, and the direction of the elastic force exerted by the elastic element on the moving ball is parallel to the length direction of the moving housing.

[0007] As a preferred technical solution, the end of the elastic element away from the movable roller is fixed to the movable housing.

[0008] Furthermore, in the above-described adaptive terrain mountain photovoltaic support foundation adjustment device, the moving ball is rotatable relative to the elastic element.

[0009] To increase the friction between the movable housing and the photovoltaic support, a rubber layer is also provided around the outer side of the movable housing, and the rubber layer is symmetrically arranged about the central axis of the movable housing.

[0010] Furthermore, in the above-described adaptive terrain mountain photovoltaic support foundation adjustment device, the two ends of the movable outer shell are configured as convergence ports, and the inner diameter of the convergence ports is smaller than the diameter of the movable ball bearings.

[0011] In order to ensure that the elastic element provides stable elastic force to the moving ball and to prevent the moving ball from getting stuck on the surface of the elastic element, the diameter of the moving ball is larger than the inner diameter of the elastic element and smaller than the inner diameter of the moving housing.

[0012] Furthermore, in the above-described adaptive terrain mountain photovoltaic support foundation adjustment device, the second reinforcing plate is configured with a Z-shaped structure, and the sides of the Z-shaped second reinforcing plate are respectively attached to the sides of the longitudinal support and the bottom of the photovoltaic panel.

[0013] Furthermore, in the above-described adaptive terrain mountain photovoltaic support foundation adjustment device, the first reinforcing plate is configured with an L-shaped structure, and the outer surface of the L-shaped first reinforcing plate is respectively attached to the side of the horizontal support and the longitudinal support.

[0014] The beneficial effects of this utility model are as follows: This invention features a movable outer shell inside a photovoltaic bracket with an internal track. Fixing bolts are fixedly installed on the surface of the movable outer shell, with one end of each bolt extending out of the photovoltaic bracket. The photovoltaic bracket consists of mutually perpendicular horizontal and vertical supports. A first reinforcing plate is installed at the connection between the horizontal and vertical supports, and a second reinforcing plate is installed at the connection between the vertical support and the photovoltaic panel. By extending the fastening bolts inside the photovoltaic bracket, the horizontal and vertical supports are connected, achieving a connection between the photovoltaic bracket and the reinforcing plate support and improving the fastening capability.

[0015] In addition, the installation of moving balls at both ends of the movable housing and the internal installation of elastic components can effectively reduce the resistance of the movable housing moving inside the photovoltaic support. Furthermore, when there is mud and sand inside the photovoltaic support, the structure composed of elastic components and moving balls can transform sliding friction into rolling friction, thereby reducing the impact of mud and sand mixing and greatly reducing the resistance of movement.

Detailed Implementation

[0019] Example Given the numerous challenges posed by the complex and varied mountainous terrain to the installation and stable operation of the photovoltaic support bracket 1, this embodiment provides a terrain-adaptive foundation adjustment device for the mountainous photovoltaic support bracket 1 to achieve stable installation and efficient adjustment of the photovoltaic support bracket 1 in complex terrain. Figure 1-4 As shown, the overall structure of the device includes a photovoltaic support 1 with a preset track and a photovoltaic panel 2 set on top of the photovoltaic support 1. The preset track inside the photovoltaic support 1 has a convex cross-sectional shape, and the track is provided with openings on the four sides of the photovoltaic support 1. In addition, the photovoltaic support 1 serves as the supporting foundation of the entire device, and a frame structure is formed by mutually perpendicular horizontal supports 11 and vertical supports 12 to provide support for the photovoltaic panel 2.

[0020] A movable housing 4 is also installed inside the track of the photovoltaic support 1. Both ends of the movable housing 4 facing the track sidewall have countersunk holes, and movable ball bearings 5 ​​are installed inside these countersunk holes. To ensure the normal operation of the movable ball bearings 5, they cannot detach from the countersunk holes, and the length of the movable ball bearings 5 ​​extending out of the movable housing 4 is less than the radius of the movable ball bearings 5. This design ensures that the movable ball bearings 5 ​​can contact the track sidewall and roll. Simultaneously, both ends of the movable housing 4 are designed with converging openings. To prevent the movable ball bearings 5 ​​from falling out of the countersunk holes, the inner diameter of the converging openings is smaller than the diameter of the movable ball bearings 5.

[0021] An elastic element 6 is provided between the movable ball bearing 5 and the movable housing. In this embodiment, the elastic element 6 is an elastic spring. One end of the elastic element 6, away from the movable roller, is fixed to the movable housing, and the other end is in contact with the surface of the movable ball bearing 5. The direction of the elastic force exerted on the movable roller by the elastic element 6 is parallel to the length direction of the movable housing 4. A fixing bolt 7 extending from the track of the photovoltaic bracket 1 is also provided in the middle of the surface of the movable housing 4. The fixing bolt 7 is used to fix the movable device to other components.

[0022] In order to smoothly achieve the rolling of the movable ball 5 inside the movable housing 4, the diameter of the movable ball 5 is smaller than the inner diameter of the movable housing 4, and the structure of the movable ball 5 having a larger diameter than the inner diameter of the elastic element 6 enables the elastic element 6 to stably apply elastic force to the movable ball 5, avoiding the phenomenon of the movable ball 5 and the elastic element 6 getting stuck due to the small diameter of the movable ball 5. In addition, the movable ball 5 can rotate relative to the elastic element 6, reducing the frictional resistance during movement.

[0023] To enhance the stability of the connection between the components of the photovoltaic bracket 1, a first reinforcing plate 31 is provided at the connection between the horizontal bracket 11 and the vertical bracket 12. The first reinforcing plate 31 has an L-shaped structure. The outer surface of the L-shaped first reinforcing plate 31 is respectively attached to the side of the horizontal bracket 11 and the vertical bracket 12. The first reinforcing plate 31 is connected to the fixing bolts 7 extending from the vertical bracket 12 and the horizontal bracket 11. The first reinforcing plate 31 is fixed to the movable outer shell 4 by the fixing bolts 7, which effectively improves the connection strength between the horizontal bracket 11 and the vertical bracket 12. In addition, a second reinforcing plate 32 is provided at the connection between the longitudinal support 12 and the photovoltaic panel 2. The second reinforcing plate 32 is Z-shaped. The horizontal and vertical plates of the Z-shaped second reinforcing plate 32 are perpendicular to each other. The horizontal and vertical plates of the Z-shaped second reinforcing plate 32 are respectively attached to the side of the longitudinal support 12 and the bottom of the photovoltaic panel 2. The second reinforcing plate 32 is connected to the fixing bolts 7 extending from the longitudinal support 12, thereby realizing a stable connection between the photovoltaic panel 2 and the longitudinal support 12. It also makes it easy to adjust the angle of the photovoltaic panel 2 according to the terrain.

[0024] To reduce friction during the connection process between the movable housing 4 and the photovoltaic support 1 and enhance the stability of the connection, a rubber layer 8 is also provided around the outer side of the movable housing 4. The rubber layer 8 is symmetrically arranged about the central axis of the movable housing 4. Please refer to the appendix. Figure 1-4 When using this device, firstly, the horizontal support 11 and the vertical support 12 are arranged at a preset angle to form a support frame. At this time, no fastening is required; their relative positions can be maintained by temporary fixing to reserve operating space for the subsequent installation of the moving device. The specific installation steps are as follows: Step 1: Installation between the longitudinal support 12 and the transverse support 11: The movable housing 4, pre-installed with the elastic element 6 and the movable ball bearing 5, is embedded into the preset tracks of the transverse support 11 and the longitudinal support 12, ensuring that the movable ball bearing 5 in the countersunk holes at both ends of the movable housing 4 is in close contact with the sidewalls of the tracks, and that the portion of the movable ball bearing 5 extending out of the movable housing 4 can roll along the inner wall of the tracks. The two outer surfaces of the L-shaped first reinforcing plate 31 are respectively attached to the sides of the transverse support 11 and the longitudinal support 12. At this time, the fixing bolts 7 extending from the surface of the movable housing 4 within the tracks of the transverse support 11 and the longitudinal support 12 will pass through the preset holes in the first reinforcing plate 31, and the fixing bolts 7 will be tightened with nuts, achieving a fixed connection between the transverse support 11 and the longitudinal support 12. Simultaneously, the rubber layer 8 contacts and is compressed against the top of the photovoltaic support 1.

[0025] Step 2: Installation of the longitudinal support 12 and the photovoltaic panel 2 support: Using the same method as in Step 1, install the movable housing 4 with elastic element 6 and moving ball bearings 5 ​​into the preset track of the longitudinal support 12, ensuring that the moving ball bearings 5 ​​in the countersunk holes at both ends of the movable housing 4 are in close contact with the side wall of the track, and the rubber layer 8 is in contact with the top of the track. Move the photovoltaic panel 2 to the preset position above the longitudinal support 12, and take the Z-shaped second reinforcing plate 32, making its vertical plate fit against the bottom of the photovoltaic panel 2 and its horizontal plate fit against the side of the longitudinal support 12. The fixing bolts 7 extending from the movable housing 4 inside the track of the longitudinal support 12 pass through the preset holes in the horizontal plate of the second reinforcing plate 32, and tighten the fixing bolts 7 with nuts to complete the connection between the photovoltaic panel 2 and the longitudinal support 12.

[0026] In addition, during use, when there is slight subsidence in the mountainous terrain or when the photovoltaic mounting bracket is subjected to external loads, the movable outer shell 4 can move appropriately within the track of the photovoltaic bracket 1 via the movable ball bearing 5. The elastic element 6 will generate corresponding elastic deformation according to the movement, which plays a role in buffering and adjustment, avoiding stress concentration at the connection points, and ensuring that the photovoltaic panel 2 can maintain a good working condition in complex mountainous terrain, thereby ensuring the light energy conversion efficiency.
