A wind and sand resistant photovoltaic support

Abstract

This utility model discloses a wind-resistant photovoltaic support frame, including a support frame with a support column installed on its inner side. A rotatable guide plate is installed on the support column to guide wind and sand. A photovoltaic module is installed on the top of the support frame, and a dust removal mechanism is installed on the photovoltaic module to remove wind and sand from the photovoltaic panel. This utility model, by installing the guide plate below the bottom of the photovoltaic module, causes the end of the guide plate in contact with the wind to be blown up and tilted when wind and sand blow, thus guiding the wind and preventing it from directly impacting the bottom of the photovoltaic module. This significantly improves the support frame's ability to resist wind and sand. After the wind and sandstorm subsides, the dust removal mechanism slides back and forth across the surface of the photovoltaic panel to remove sand and dust, ensuring the effectiveness of the photovoltaic panel.

Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel support technology, specifically a wind and sand resistant photovoltaic support. Background Technology

[0002] Photovoltaic panel supports are crucial components used to support and secure photovoltaic (PV) panels. They play a key role in PV power generation systems, ensuring the panels can be stably installed on the ground, roof, or other building surfaces. PV panel supports are typically made of metal materials such as aluminum alloys and steel, offering high strength and corrosion resistance. They allow for adjustment of the PV panel's angle, enabling the panels to maximize sunlight absorption based on the sun's position, thus improving power generation efficiency. Common types of PV panel supports include fixed supports, adjustable supports, and tracking supports.

[0003] A search revealed that a wind-resistant photovoltaic support system was mentioned in the publicly available application number 202321211399.9.

[0004] While the above solution addresses the issues mentioned in the background section, it still has the following shortcomings: 1. The construction cost is relatively high, and the photovoltaic panels cannot be installed at an angle, thus failing to absorb sunlight effectively; 2. After desert sandstorms, sand and dust accumulate on the photovoltaic panels, which cannot be cleaned, severely affecting the performance of the photovoltaic panels.

[0005] Therefore, a wind and sand resistant photovoltaic support system was proposed to solve the above problems. Utility Model Content

[0006] 1. Technical problem to be solved by the utility model

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wind and sand resistant photovoltaic support, which aims to solve the problems that the existing photovoltaic panel support cannot guide wind and sand and cannot clean the photovoltaic panels of sand and dust after the wind and sand.

[0008] 2. Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A wind-resistant photovoltaic support includes a support frame, a support column installed on the inner side of the support frame, a guide plate that can rotate to guide wind and sand on the support column, a photovoltaic module installed on the top of the support frame, and a dust removal mechanism installed on the photovoltaic module to remove wind and sand from the photovoltaic panel.

[0009] Furthermore, the support column is buried in the ground at the center of the bottom of the bracket. A reinforcing rod is welded to the outer ring surface of the bottom of the support column and to the four support legs of the bracket. A reinforcing plate is installed on the top of the support column and connected to the bottom of the photovoltaic module by bolts.

[0010] The above technical solution strengthens the support column and improves the overall support stability of the support structure.

[0011] Furthermore, the guide plate is located below the bottom of the photovoltaic module and its tilt angle is the same as that of the photovoltaic module. The bottom of the guide plate has a bend parallel to the ground. A connecting hole is provided on the top inclined surface of the guide plate. Rotating shafts are symmetrically installed on the inner two sides of the connecting hole. Rotating holes that match the size of the rotating shafts and are rotatably connected are symmetrically provided on the outer two sides of the support column.

[0012] The above technical solution enables the guide plate to rotate within a certain angle range on the outer ring surface of the support column.

[0013] Furthermore, two vertically sliding blocks are symmetrically installed on both sides of the outer ring surface of the support column, and the bottom of the two sliding blocks is inclined and fits against the top inclined surface of the guide plate in the initial state.

[0014] The above technical solution ensures that when the guide plate rotates on the support column, whether it rotates clockwise or counterclockwise, it will squeeze a sliding block, causing the sliding block to slide vertically upward.

[0015] Furthermore, a spring is installed on the top of each of the two sliding blocks, and a fixing block is connected to the top of each of the two springs. One end of the fixing block is fixedly installed on the outer ring surface of the support column.

[0016] The above technical solution enables the sliding block to compress the spring when it slides vertically upwards. This elastic force can drive the guide plate to return to its original shape after the wind disappears.

[0017] Furthermore, a U-shaped plate is installed on the dust removal mechanism. The bottom two ends of the U-shaped plate are attached to the top two inclined surfaces of the photovoltaic module. A slider is installed at the bottom two ends of the U-shaped plate. A sliding groove is opened at the top two ends of the photovoltaic module to slide with the slider. A lead screw is bolted between the two sides of the slider. A second motor is installed at one end of each lead screw. The slider is located inside the frame groove of the photovoltaic module. The two lead screws and the second motor are respectively installed inside the frame of the photovoltaic module. The lead screw is rotatably connected inside the frame of the photovoltaic module.

[0018] The above technical solution enables the U-shaped plate to slide back and forth between the top two ends of the photovoltaic module via sliders when the second motor drives the lead screw to rotate.

[0019] Furthermore, a rubber roller is rotatably connected between the two ends of the U-shaped groove of the U-shaped plate, the rubber roller is in contact with the surface of the photovoltaic panel, and a first motor for driving the rubber roller to rotate is installed at one end of the U-shaped plate.

[0020] The above technical solution enables the first motor to drive the rubber roller to rotate, which in turn slides back and forth on the top inclined surface of the photovoltaic panel with the U-shaped plate, thereby cleaning the sand and dust on the surface of the photovoltaic panel. This eliminates the need for manual cleaning and ensures the efficiency of the photovoltaic panel.

[0021] 3. Beneficial effects Compared with the prior art, the beneficial effects of this utility model are: In this utility model, the following effects can be achieved by setting an anti-sand photovoltaic support: 1. The two ends of the guide plate of this device can rotate on the support column. During the rotation, the slider will be squeezed to slide upward and compress the spring. After the guide plate rotates, it will block the bottom of the photovoltaic panel and form a guide surface to guide the sand and dust out from the bottom of the guide plate, greatly reducing the pressure exerted by the wind on the bottom of the photovoltaic panel. After the wind disappears, the guide plate will return to its original shape under the action of the spring; 2. After the second motor starts, it drives the lead screw to rotate. When the lead screw rotates, it drives the U-shaped plate to slide up and down at both ends of the top frame of the photovoltaic panel. The first motor drives the rubber roller to rotate and scrape the surface of the photovoltaic panel, cleaning the sand and dust on the surface of the photovoltaic panel. Thus, the cleanliness of the photovoltaic panel surface is guaranteed without manual cleaning, making the photovoltaic panel more efficient when used. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are provided. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0026] Example 1: Please see Figure 1 - Figure 4 This embodiment provides a wind-resistant photovoltaic support bracket, including a bracket 1, a support column 2 installed on the inner side of the bracket 1, a guide plate 3 that can rotate to guide wind and sand on the support column 2, a photovoltaic module 4 installed on the top of the bracket 1, and a dust removal mechanism 5 installed on the photovoltaic module 4 to remove wind and sand from the photovoltaic panel. The guide plate 3 is installed below the bottom of the photovoltaic module 4. When wind and sand blow, the end of the guide plate 3 that is in contact with the wind will be blown up and tilted, thus guiding the wind and preventing the wind from being directly applied to the bottom of the photovoltaic module 4, thereby greatly improving the wind and sand resistance of the bracket 1 to the photovoltaic module 4. After the wind and sand blows, the dust removal mechanism 5 can slide back and forth on the surface of the photovoltaic panel to remove the sand and dust, thereby ensuring the performance of the photovoltaic panel.

[0027] Example 2: Please see Figure 1-4 Based on embodiment 1, this embodiment further defines that two vertically sliding blocks 22 are symmetrically installed on both sides of the outer ring surface of the support column 2. The bottom of the two sliding blocks 22 is inclined and fits against the top inclined surface of the guide plate 3 in the initial state. When the wind blows, if the wind blows to the higher end of the guide plate 3 first, the guide plate 3 rotates clockwise on the support column 2 and squeezes the corresponding sliding block 22 to slide upward a distance. If the wind blows to the lower end of the guide plate 3, the guide plate 3 rotates counterclockwise and squeezes the corresponding sliding block 22 to slide upward a distance.

[0028] Example 3: Please see Figure 4Based on embodiment 1, this embodiment further specifies that springs 24 are installed on the top of both sliding blocks 22, and fixed blocks 23 are connected to the top of both springs 24. One end of the fixed block 23 is fixedly installed on the outer ring surface of the support column 2. When the sliding block 22 moves upward, it will compress the spring 24. At the same time, the guide plate 3 rotates and tilts at the bottom of the photovoltaic module 4 to form a guide surface to block the ground of the photovoltaic module 4. The bottom of the guide plate 3 is used to guide the wind force away, thereby greatly reducing the pressure of the wind on the photovoltaic module 4, providing the photovoltaic support with wind and sand resistance. After the wind disappears, the guide plate 3 will rotate back to its original position under the action of the spring 24.

[0029] Example 4: Please see Figure 1 and Figure 5 Based on Embodiment 1, this embodiment further specifies that a U-shaped plate 51 is installed on the dust removal mechanism 5. The bottom two ends of the U-shaped plate 51 are attached to the top two inclined surfaces of the photovoltaic module 4. A slider 54 is installed at the bottom two ends of the U-shaped plate 51. The top two ends of the photovoltaic module 4 are provided with sliding grooves that are slidably connected to the slider 54. A lead screw 55 is bolted between the two sides of the slider 54. A second motor 56 is installed at one end of each lead screw 55. The slider 54 is located inside the frame groove of the photovoltaic module 4. The two lead screws 55 and the second motor 56 are respectively installed inside the frame of the photovoltaic module 4. The lead screws 55 are rotatably connected inside the frame of the photovoltaic module 4. When the second motor 56 is started, it drives the lead screw 55 to rotate. At this time, the lead screw 55 drives the slider 54 to slide back and forth in the sliding grooves at both ends of the frame of the photovoltaic module 4, so that the U-shaped plate 51 slides up and down on the top inclined surface of the photovoltaic module 4.

[0030] Example 5: Please see Figure 1 and Figure 5 Based on Embodiment 1, this embodiment further specifies that a rubber roller 52 is rotatably connected between the two ends of the U-shaped groove inside the U-shaped plate 51. The rubber roller 52 is in contact with the surface of the photovoltaic panel. A first motor 53 for driving the rubber roller 52 to rotate is installed at one end of the U-shaped plate 51. During the back-and-forth sliding of the U-shaped plate 51 on the top of the photovoltaic panel, the first motor 53 is started to drive the rubber roller 52 to rotate. The rubber roller 52 will scrape and remove dust from the surface of the photovoltaic panel while moving, thereby cleaning the sand and dust on the surface of the photovoltaic panel without the need for manual cleaning that takes a lot of time, thus ensuring the efficiency of the photovoltaic panel.

[0031] Working principle: When the photovoltaic support is in use, if the wind blows sand first to the higher end of the guide plate 3, the guide plate 3 will rotate clockwise on the support column 2 and press the corresponding sliding block 22 to slide upward a certain distance. If the wind blows to the lower end of the guide plate 3, the guide plate 3 will rotate counterclockwise and press the corresponding sliding block 22 to slide upward a certain distance. When the sliding block 22 moves upward, it will compress the spring 24. At the same time, the guide plate 3 rotates and tilts at the bottom of the photovoltaic module 4 to form a guide surface to block the ground of the photovoltaic module 4. The bottom of the guide plate 3 is used to guide the wind force away, thereby greatly reducing the pressure of the wind on the photovoltaic module 4, providing the photovoltaic support with wind and sand resistance. After the wind disappears, the guide plate 3 will rotate back to its original position under the action of the spring 24. When the second motor 56 starts, it drives the lead screw 55 to rotate. At this time, the lead screw 55 drives the slider 54 to slide back and forth in the grooves at both ends of the photovoltaic module 4 frame, so that the U-shaped plate 51 slides up and down on the top inclined surface of the photovoltaic module 4. During the back and forth sliding of the U-shaped plate 51 on the top of the photovoltaic panel, the first motor 53 starts to drive the rubber roller 52 to rotate. The rubber roller 52 will scrape and remove dust from the surface of the photovoltaic panel while moving, thus cleaning the sand and dust on the surface of the photovoltaic panel. There is no need for manual cleaning that takes a lot of time, ensuring the efficiency of the photovoltaic panel.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Without departing from the concept of this technical solution, any obvious substitution is within the protection scope of this utility model.
