Description

An easy-to-install wind and snow resistant photovoltaic bracket Technical Field

[0001] This invention relates to the field of photovoltaic support technology, specifically to a wind and snow resistant photovoltaic support that is easy to install. Background Technology

[0002] In the construction and operation of photovoltaic power plants, the photovoltaic support structure, as a key structure supporting photovoltaic modules, directly affects the safety, stability, and power generation efficiency of the power plant. Existing technologies already include photovoltaic support structures that facilitate the installation of photovoltaic panels; however, to better enable photovoltaic support structures to withstand harsh natural environmental conditions such as wind and snow, a wind and snow resistant photovoltaic support structure that is easy to install has been designed.

[0003] However, existing wind and snow resistant photovoltaic (PV) brackets, which are easy to install, tend to accumulate large amounts of snow on their surfaces after snowfall. For thicker snow layers, a scraper is typically used to push the snow from top to bottom. However, when the snow layer is thick and the weather is cold, the upper layer of the snow is a soft layer, while the bottom layer forms an ice layer. The ice layer has a strong adhesion to the PV panel, making it difficult to remove it directly by pushing. To remove the ice layer, a large pushing force is needed to overcome the adhesion of the ice layer. At this point, because the ice layer has a strong adhesion to the PV panel, it may damage the PV panel during snow removal, thus reducing the safety of snow removal. Summary of the Invention

[0004] This invention provides an easy-to-install wind and snow resistant photovoltaic bracket. Before snow removal, the bracket inserts into the ice layer to break the ice, thus solving the problem mentioned in the background art that the entire ice layer has a large adsorption force on the photovoltaic panel surface, making it inconvenient to push the snow.

The airbag expands outward through the outward expansion part, moves out of the second storage groove, and fills the gap between the outward expansion part and the main core.

[0009] As an optional solution for the wind and snow resistant photovoltaic bracket that is easy to install according to the present invention, the second lifting plate has a first air chamber inside, a piston plate is slidably arranged in the first air chamber, a protruding plate is fixed on the surface of the core column, a transmission rod is fixed between the protruding plate and the piston plate, and a second air chamber is opened inside the main core that communicates with the first air chamber, and the second air chamber communicates with the airbag.

[0010] As an optional solution for the wind and snow resistant photovoltaic bracket that is easy to install according to the present invention, a connecting rod is fixed between the movable plate and the outer expansion part, a first air guide pipe is connected to one side of the second air chamber, a second air guide pipe is slidably arranged inside the first air guide pipe, an air guide groove is provided between the airbag and the movable plate, and the end of the second air guide pipe is connected to the air guide groove.

[0011] As an optional solution for the wind and snow resistant photovoltaic bracket that is easy to install according to the present invention, the fixed frame is provided with a sliding groove, and a reciprocating screw is rotatably arranged inside the sliding groove. A servo motor is fixed at the end of the fixed frame, and the output end of the servo motor is fixed to the reciprocating screw.

[0012] As an optional solution for the wind and snow resistant photovoltaic bracket that is easy to install according to the present invention, a baffle is elastically provided on the upper surface of the sliding groove, and an inclined surface is provided at one end of the baffle. An abutment rod is fixed on the surface of the gantry frame, and the baffle opens the sliding groove by abutting against the inclined surface through the abutment rod.

[0013] As an optional solution for the wind and snow resistant photovoltaic bracket that is easy to install according to the present invention, a positioning block is fixed on the surface of the fixing frame, a third storage groove is opened inside the positioning block, an adjusting rod is fixed on the surface of the baffle, one end of the adjusting rod is slidably disposed in the third storage groove, and a second spring is fixed between the adjusting rod and the inner wall of the third storage groove.

[0014] As an optional solution for the wind and snow resistant photovoltaic support that is easy to install according to the present invention, the outer surface of the foundation pile is fixed with a clamp, two columns are fixed between the clamp and the fixing frame, and horizontal and vertical strips and diagonal strips for strengthening the connection are fixed between the two columns. An inclined support rod is also fixed between the clamp and the fixing frame.

[0015] The present invention has the following beneficial effects:

[0016] 1. This easy-to-install wind and snow resistant photovoltaic bracket can break the ice by inserting the posts into the ice layer at the bottom of the snow before the pusher plate is used for snow removal. After breaking the ice, several sets of holes formed on the ice layer allow air to enter, which greatly reduces the adhesion of the entire ice layer to the surface of the photovoltaic panel. Since the adhesion of the ice layer has been reduced, the pusher plate can push the snow layer on the surface of the photovoltaic panel more easily, which significantly reduces the pushing force required for snow removal and avoids damage to the photovoltaic panel that may be caused by excessive pushing force, thereby effectively improving the safety of the snow removal process.

[0017] 2. This easy-to-install wind and snow resistant photovoltaic bracket, when the insert column is inserted into the ice layer, moves the core column downward relative to the main core, allowing the top rod to extend the outward expansion section relative to the main core. This outward expansion section can expand the ice layer outward, making the ice layer easier to break. This increases the likelihood of the ice layer breaking into several small pieces after the main core is inserted into the ice layer, which is beneficial for improving the ice-breaking effect. In turn, it reduces the adhesion of the ice layer to the photovoltaic panel surface, making it easier to push the material.

[0018] 3. This easy-to-install wind and snow resistant photovoltaic bracket, when the outward extension section extends outward relative to the main core section, can move the airbag out of the second storage slot and inflate it through the linkage of connecting rods, moving plates, and other structures. The inflated airbag can fill the gap between the outward extension section and the main core section, effectively preventing snow from squeezing into the gap and thus preventing snow from hindering the normal repositioning of the outward extension section. At the same time, the airbag is inflated during the process of moving out of the second storage slot, while the part that is not moved out will not inflate due to the restriction of the second storage slot. This ensures that the part of the airbag that is moved out can always remain in an inflated state, ensuring... The continuous and effective filling of gaps further improves the reliability and effectiveness of gap filling, resulting in better snow removal. During the process of the airbag retracting and retracting into the second storage slot, the piston plate resets and gradually draws the gas inside the airbag into the second and first air chambers. This process causes the part of the airbag that has been retracted into the second storage slot to become deflated, while the part that has not been retracted remains in an inflated state. This design avoids wrinkles in the airbag that has not been fully retracted, thus ensuring that the airbag can be smoothly and unobstructedly retracted into the second storage slot, guaranteeing the convenience and smoothness of the storage work.

[0019] 4. This easy-to-install wind and snow resistant photovoltaic bracket, when not in snow removal mode, has a baffle covering the upper surface of the sliding groove, effectively reducing snow accumulation inside the sliding groove; when snow removal is carried out, the gantry slides along the sliding groove and drives the abutment rod to move. The abutment rod first contacts the inclined surface, causing the baffle to open to both sides of the sliding groove. After the baffle is fully opened, the sliding groove is opened, thus ensuring that the gantry can slide smoothly along the sliding groove, ensuring the normal progress of snow removal work, and further improving the snow removal effect.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1, please refer to Figures 1-11, shows an easy-to-install wind and snow resistant photovoltaic support, including a base pile 1 and a fixing frame 3 for installing photovoltaic panels 2. The fixing frame 3 is fixedly connected to the base pile 1. A horizontal plate 4 is slidably arranged on the fixing frame 3, and a snow removal push plate 5 is fixed to the surface of the horizontal plate 4. A gantry frame 6 is also slidably arranged on the fixing frame 3. A first lifting plate 7 and a second lifting plate 8 are slidably arranged on the inner side of the gantry frame 6. An ice-breaking insert 9 is fixed to the lower surface of the second lifting plate 8. An electric push rod 15 is fixed to the top of the gantry frame 6. The output end of the push rod 15 is fixed to the surface of the first lifting plate 7; a sliding groove 30 is provided on the fixed frame 3, and a reciprocating screw 31 is rotatably arranged inside the sliding groove 30; a servo motor 32 is fixed to the end of the fixed frame 3, and the output end of the servo motor 32 is fixed to the reciprocating screw 31; a clamp 40 is fixed to the outer surface of the foundation pile 1, and two columns 41 are fixed between the clamp 40 and the fixed frame 3; horizontal and vertical bars 42 and diagonal bars 43 for strengthening the connection are fixed between the two columns 41; and a diagonal support rod 44 is also fixed between the clamp 40 and the fixed frame 3.

[0034] In this technical solution, the photovoltaic panel 2 is fixed to the photovoltaic bracket by clamping blocks and T-screws, thus completing the installation of the photovoltaic panel 2. The operation is convenient, and the installation of the photovoltaic panel 2 is existing technology and not an innovation of this application, so it will not be described in detail. In this application, as shown in Figure 1, the foundation pile 1 is compacted into the ground, and then the clamp 40 is fixed to the foundation pile 1. The fixing frame 3 and the clamp 40 are connected by the column 41 and the diagonal support rod 44, and fixed by fastening bolts, thus realizing the installation and fixing of the fixing frame 3. The connection strength of the structure is strengthened by the horizontal and vertical bars 42 and the diagonal bars 43, thereby improving the wind and snow resistance of the photovoltaic bracket and improving the performance. After snowfall, the surface of the photovoltaic panel 2 is prone to accumulation. For larger snowfalls and thicker snow layers, snow removal typically involves using a scraper to push the snow from top to bottom. However, when the snow layer is thick and the weather is cold, the upper layer of the snow is a soft layer, while the bottom layer forms an ice layer. The ice layer has a strong adhesion to the photovoltaic panel 2, making it difficult to remove it directly by pushing. To remove the ice layer, a large pushing force is needed to overcome the adhesion of the ice layer. Because of the strong adhesion of the ice layer to the photovoltaic panel 2, the photovoltaic panel 2 may be damaged during snow removal, thus reducing the safety of snow removal. To address this issue, as shown in Figures 3 and 4, during snow removal, the reciprocating screw 31 includes a left screw... The left lead screw 311 and the right lead screw 312 are threaded together at the bottom of the gantry 6. A slider 401 is fixed on the surface of the horizontal plate 4 and threaded together with the right lead screw 312. First, the left lead screw 311 is rotated by the servo motor 32 on the left side. The left lead screw 311 drives the gantry 6 to move from left to right. The gantry 6 drives the insertion post 9 to move from left to right, so that the insertion post 9 moves along the snow layer on the surface of the photovoltaic panel 2. During the movement of the insertion post 9, the extension and retraction of the electric push rod 15 drives the first lifting plate 7 and the second lifting plate 8 to move up and down. The second lifting plate 8 drives the insertion post 9 to move up and down, so that the insertion post 9 can be inserted into the snow layer until it is inserted into the cold layer, thereby breaking the ice. When the insertion post 9 reaches its lowest position, its bottom end will not contact the surface of the photovoltaic panel 2, thus avoiding damage to the photovoltaic panel 2. After the ice breaking is completed, several sets of holes are formed on the ice layer to facilitate air entry, thereby reducing the adsorption force of the entire ice layer on the surface of the photovoltaic panel 2. Then, when the gantry 6 moves to the rightmost end, the servo motor 32 on the right side drives the right lead screw 312 to rotate. The right lead screw 312 drives the slider 401 to move. The slider 401 drives the horizontal plate 4 to move. The horizontal plate 4 drives the push plate 5 to move, so that the push plate 5 pushes the snow layer on the surface of the photovoltaic panel 2, thereby facilitating snow removal. After the snow removal is completed, the right lead screw 312 drives the push plate 5 to reset first, and then the left lead screw 311 drives the insertion post 9 to reset.

[0035] In Example 2, when the insert 9 is inserted into the ice layer, although holes are formed in the ice layer, some areas may crack while others may not, resulting in large chunks of ice remaining and strong adhesion, leading to poor ice-breaking effect. To address this issue, this example is an improvement on Example 1. Specifically, please refer to Figures 1-11. The insert 9 includes a main core 901, with a pointed tip 902 fixed to its bottom end. Extended portions 903 are slidably arranged on both sides of the main core 901. A core column 10 is fixed to the lower surface of the first lifting plate 7, and the core column 10 passes through the second lifting plate 8 and is slidably connected to the main core 901. A top rod 11 is fixed to the inner side of the extended portions 903. The surface of the core column 10... The surface of the gantry 6 is provided with a first sliding groove 12 for the top rod 11 to slide. The end of the top rod 11 is fixed with a sliding protrusion 13. The inner wall of the first sliding groove 12 is provided with an inclined groove 14. The outward expansion 903 expands outward by sliding along the inclined groove 14 through the sliding protrusion 13. The surface of the gantry 6 is fixed with a stop block 16 for limiting the second lifting plate 8. A telescopic rod 17 is elastically provided between the first lifting plate 7 and the second lifting plate 8. The telescopic rod 17 includes a first support rod 171 fixed to the first lifting plate 7 and a second support rod 172 fixed to the second lifting plate 8. The interior of the second support rod 172 is provided with a first storage groove 173 for the first support rod 171 to slide. A first spring 174 is fixed between the first support rod 171 and the bottom wall of the first storage groove 173.

[0036] In this technical solution, when the insertion post 9 is inserted into the ice layer, the outward expansion portion 903 can extend outward relative to the main core portion 901, allowing the outward expansion portion 903 to expand the ice layer outward, making the ice layer easier to break. This increases the likelihood of the ice layer breaking into several small pieces after the insertion post 9 is inserted, which is beneficial for improving the ice-breaking effect and reducing the adhesion of the ice layer to the surface of the photovoltaic panel 2, making it easier to push the material. The specific movement state of the outward expansion portion 903 is as follows: First, the electric push rod 15 pushes the first lifting plate 7 downward. The resistance of the ice layer to the telescopic rod 17 is insufficient to make the ice layer break into smaller pieces. When the telescopic rod 17 retracts, the first lifting plate 7 will drive the second lifting plate 8 to move downwards simultaneously. The second lifting plate 8 will drive the insert 9 to move downwards, so that the insert 9 is inserted into the ice layer until the second lifting plate 8 contacts the stop block 16, preventing the second lifting plate 8 and the insert 9 from moving downwards any further. Then, the electric cam will continue to push the first lifting plate 7 downwards. At this time, the first lifting plate 7 moves downwards relative to the second lifting plate 8. The first lifting plate 7 will drive the core column 10 to move downwards, so that the core column 10 moves downwards relative to the main core 901, as shown in Figures 6 and 7. The core column 10 moves downward, causing the push rod 11 to slide along the first groove 12. The push rod 11 drives the sliding protrusion 13 to slide along the inclined groove 14, causing the sliding protrusion 13 to drive the push rod 11 to extend outward. The push rod 11 drives the outward expansion portion 903 to extend outward, so that when the main core 901 is inserted into the ice layer, the outward expansion portion 903 expands outward, making it easier for the ice layer to expand outward. The push rod 11 penetrates the main core 901 and slides with the main core 901, so that the push rod 11 can only move horizontally along the main core 901 and will not penetrate further. The offset in other directions allows the top rod 11 to stably drive the outward expansion part 903 to expand outward. In this technical solution, when the first lifting plate 7 moves downward relative to the second lifting plate 8, the first spring 174 is compressed, causing the first support rod 171 to retract into the first receiving groove 173, and the telescopic rod 17 to retract. When the first lifting plate 7 moves upward relative to the second lifting plate 8, the first spring 174 is relieved, allowing the telescopic rod 17 to extend and return to its original position. The pointed end 902 facilitates the insertion of the insertion post 9 into the ice layer, making ice breaking easier.

[0037] In Example 3, to facilitate the insertion of the insertion post 9 into the ice layer, the outward expansion portion 903 and the main core portion 901 are designed as a complete circular structure. However, when the outward expansion portion 903 extends outward, a gap is formed between the outward expansion portion 903 and the main core portion 901. Due to the existence of the gap, snow will be squeezed into the gap when the outward expansion portion 903 extends outward, thus affecting the subsequent repositioning of the outward expansion portion 903 and consequently affecting the subsequent snow removal effect. To address this problem, this embodiment is an improvement based on Example 2. Specifically, please refer to Figures 1-11. A second storage groove 18 is provided inside the main core portion 901. A movable plate 19 is slidably arranged inside the second storage groove 18. An airbag 20 is fixed between the movable plate 19 and the outward expansion portion 903. The airbag 20 expands outward through the outward expansion portion 903. Zhang is removed from the second storage slot 18 and the gap between the outer expansion 903 and the main core 901 is filled; the second lifting plate 8 has a first air chamber 21 inside, a piston plate 22 is slidably arranged in the first air chamber 21, a protruding plate 23 is fixed on the surface of the core column 10, a transmission rod 24 is fixed between the protruding plate 23 and the piston plate 22, the main core 901 has a second air chamber 25 inside that communicates with the first air chamber 21, and the second air chamber 25 communicates with the airbag 20; a connecting rod 26 is fixed between the moving plate 19 and the outer expansion 903, a first air guide pipe 27 is connected to one side of the second air chamber 25, a second air guide pipe 28 is slidably arranged inside the first air guide pipe 27, an air guide groove 29 is arranged between the airbag 20 and the moving plate 19, and the end of the second air guide pipe 28 communicates with the air guide groove 29.

[0038] In this technical solution, as shown in Figures 6, 8, and 9, when the outwardly extending portion 903 extends outward relative to the main core portion 901, the outwardly extending portion 903 pulls the moving plate 19 to slide within the second receiving groove 18 via the connecting rod 26. The moving plate 19 causes the airbag 20 to move out of the second receiving groove 18, allowing the airbag 20 to seal the gap between the outwardly extending portion 903 and the main core portion 901. Simultaneously, as the airbag 20 moves out of the second receiving groove 18, the first lifting plate 7 moves downward relative to the second lifting plate 8, causing the core column 10 to drive the protruding plate 23 to move downward. The protruding plate 23 drives the piston plate 22 to move downward via the transmission rod 24. The piston plate 22 then moves the first... The gas inside the air chamber 21 fills the second air chamber 25, and then flows through the first air guide tube 27, the second air guide tube 28, and the air guide groove 29 into the airbag 20, causing the airbag 20 to inflate. This allows the airbag 20 to fill the gap between the outward expansion portion 903 and the main core portion 901, preventing snow from getting into the gap and affecting the repositioning of the outward expansion portion 903. In this technical solution, when the airbag 20 is removed from the second storage groove 18, the airbag 20 will be inflated. Since the part of the airbag 20 that has not been removed from the second storage groove 18 is restricted by the second storage groove 18 and will not inflate, only the removed part will inflate, allowing the airbag 20 to expand from the second storage groove. The portion removed from section 18 remains in an expanded state, preventing snow from being squeezed into the gap between the outward expansion section 903 and the main core section 901, thus further improving the gap filling effect. Additionally, during the process of the airbag 20 retracting into the second storage slot 18, the airbag 20 cannot deflate first. If the airbag 20 deflates first, wrinkles will appear. When the airbag 20 retracts into the second storage slot 18, the wrinkled areas of the airbag 20 may be compressed and unable to retract into the second storage slot 18. Therefore, during the process of the airbag 20 retracting into the second storage slot 18, the piston plate 22, during its resetting process, will draw gas from inside the airbag 20 into the second air chamber 25. Then, the airbag 20 is adsorbed into the first air chamber 21 through the second air chamber 25, so that the part of the airbag 20 that is put into the second storage groove 18 is in a deflated state, while the part that is not put into the second storage groove 18 is in an inflated state. This avoids the airbag 20 that is not put into the second storage groove 18 from becoming wrinkled, thus facilitating the storage of the airbag 20. In this technical solution, the moving plate 19 is moved by the connecting rod 26. The moving plate 19 moves the airbag 20 out of the second storage groove 18, thus avoiding pulling on the airbag 20. Moreover, the second air guide tube 28 can slide relative to the first air guide tube 27, so that the ventilation effect of the airbag 20 is not affected when the airbag 20 is extended or retracted.

[0039] In Example 4, when the gantry 6 and the horizontal plate 4 move, they need to slide along the sliding groove 30. However, in snowy weather, not only will snow accumulate on the surface of the photovoltaic panel 2, but also on the sliding groove 30, thus affecting the subsequent sliding of the gantry 6 and the horizontal plate 4. To address this problem, this example is an improvement based on Example 3. Specifically, please refer to Figures 1-11. A baffle 33 is elastically provided on the upper surface of the sliding groove 30. One end of the baffle 33 has an inclined surface 34. An abutment rod 35 is fixed on the surface of the gantry 6. The baffle 33 opens the sliding groove 30 by abutting against the inclined surface 34 through the abutment rod 35. A positioning block 36 is fixed on the surface of the fixing frame 3. A third storage groove 37 is provided inside the positioning block 36. An adjusting rod 38 is fixed on the surface of the baffle 33. One end of the adjusting rod 38 is slidably disposed in the third storage groove 37. A second spring 39 is fixed between the adjusting rod 38 and the inner wall of the third storage groove 37.

[0040] In this technical solution, as shown in Figures 10 and 11, when snow removal is not required, the baffle 33 covers the upper surface of the sliding groove 30, thereby reducing snow accumulation inside the sliding groove 30. When snow removal is required, the gantry 6 slides along the sliding groove 30, and the gantry 6 drives the abutment rod 35 to move, so that the abutment rod 35 first contacts the inclined surface 34, causing the baffle 33 to open to both sides of the sliding groove 30. At the same time, the baffle 33 drives the adjusting rod 38 to retract into the third receiving groove 37 and compresses the second spring 39, so that the second spring 39 stores force, facilitating the subsequent reset of the baffle 33. After the plate 33 is fully opened, the sliding groove 30 is opened, and the gantry 6 slides into the inner side of the baffle 33. The outer surface of the gantry 6 abuts against the baffle 33 and can slide along the surface of the baffle 33, so that the gantry 6 can slide along the sliding groove 30. In this technical solution, when the gantry 6 slides to the other end of the sliding groove 30, it still abuts against the baffle 33, so that the sliding groove 30 is always in an open state, so that the slider 401 can continue to slide along the sliding groove 30. Only when the gantry 6 is reset is the abutment against the baffle 33 released, so that the baffle 33 closes the sliding groove 30 again.
