[0011] According to the above technical solution, the L-shaped piece itself has elasticity. The movement of the rectangular piece squeezes the L-shaped piece, and the deformed L-shaped piece stores energy under the action of its own elasticity. An arc surface two is formed at one end of the L-shaped piece away from the carrying box. The rectangular piece contacts the arc surface two during movement, and the rectangular piece continues to move and squeeze the L-shaped piece.

[0012] According to the above technical solution, a second scroll spring is arranged between the rectangular piece and the mounting block.

[0013] According to the above technical solution, the deceleration device includes a portal frame, a displacement plate, an elastic piece, a contact rod, a connection seat, a blocking piece, an L-shaped block and a baffle.

[0015] An installation method for a transformer installation device for photovoltaic power generation includes the following steps: Step 1: Before the transformer is fixed on the transformer pole, first pull the rotating plate to rotate away from the support plate. The surface where the rotating plate moves and contacts the support plate separates. At the same time, the rotation of the rotating plate drives the second arc-shaped sleeve to move away from the first arc-shaped sleeve. Step 2: After the second arc-shaped sleeve moves to the specified position, move the first arc-shaped sleeve to contact the circumferential surface of the cement column, close the rotating plate, and the rotation of the rotating plate drives the second arc-shaped sleeve to reset to the initial position. The second arc-shaped sleeve contacts the circumferential surface of the cement column during the movement. Step 3: Use screws and nuts to fix the first arc-shaped sleeve and the second arc-shaped sleeve on the cement column, and then repeat the above operation to fix the first arc-shaped sleeve and the second arc-shaped sleeve on the other cement column on the other side. Step 4: After the transformer is fixed on the transformer pole, place the transformer on the top of the bottom plate. The transformer contacts the inner wall of the protection frame during the movement, and then use screws and nuts to fix the transformer on the top of the bottom plate.

[0016] The present invention provides a transformer installation device for photovoltaic power generation. It has the following beneficial effects: (1) For this transformer installation device for photovoltaic power generation, after the second arc-shaped sleeve moves, move the first arc-shaped sleeve to contact the cement column. By opening the second arc-shaped sleeve, it is not necessary for the first arc-shaped sleeve and the second arc-shaped sleeve to move downward from the highest point of the cement column during fixation, effectively reducing the safety hazards in high-altitude operations. Then, through the limiting short rod and the limiting long rod applying limits to the sliding rod, the two sides of the sliding rod are limited simultaneously to increase stability, and the position of the sliding rod can also be quickly adjusted to adapt to the distance between the cement columns, reducing the time for multiple adjustments, thereby effectively improving the installation efficiency of the transformer.

[0017] (2) For this transformer installation device for photovoltaic power generation, multiple rectangular pieces and L-shaped pieces collide continuously to generate continuous vibrations, and then the vibrations are transmitted to the contacting rotating plate through the arc surface one, avoiding jams when opening the rotating plate, thereby effectively improving the smoothness of the rotation of the rotating plate and ensuring the stability of the operation during the installation process. When the rectangular pieces rotate without colliding with the L-shaped pieces, when the rotating plate is closed, the rectangular pieces and the L-shaped pieces do not trigger vibrations, avoiding the deviation of the first arc-shaped sleeve in contact with the cement column due to the influence of vibrations, improving the rationality of the vibrations and ensuring the accuracy of the installation.

[0018] (3) In the transformer installation device for photovoltaic power generation, the blocking piece exerts intermittent resistance on the contact rod, slowing down the moving speed of the contact rod. By applying intermittent resistance to the contact rod, the speed of the rotating plate during reset is controlled to ensure that after the operator releases the rotating plate, the second arc-shaped sleeve can be reset at a safe speed, thereby effectively improving the installation stability. When the elastic piece restores, it drives the displacement plate to move, and the movement of the displacement plate provides an additional thrust to the cylindrical rod. When the rotating plate is opened, the displacement plate exerts an additional force on the cylindrical rod to ensure that the telescopic plate can smoothly move to the designated position before the second arc-shaped sleeve closes.

Detailed Implementation Modes

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 - 5 , an embodiment of the present invention is: a transformer installation device for photovoltaic power generation, including a bottom plate 1. A protection frame 2 is fixedly installed on the top of the bottom plate 1. A support plate 3 is fixedly installed on the surface of the bottom plate 1. A chute is provided on the inner wall of the support plate 3. A limiting groove is provided on one side of the support plate 3 close to the chute. A fixing device is also included; wherein, the fixing device includes a sliding rod 4, a moving plate 5, a first arc-shaped sleeve 6, a connecting plate 7, a rotating plate 8, a second arc-shaped sleeve 9, a grip rod 10, a first spring 11, a limiting short rod 12, and a limiting long rod 13. The sliding rod 4 is slidably installed inside the chute. The moving plate 5 is fixedly installed on the circumferential surface of the sliding rod 4. The moving plate 5 is slidably installed on the inner wall of the support plate 3. The first arc-shaped sleeve 6 is fixedly penetrated through the inner and outer walls of the moving plate 5. The connecting plate 7 is fixedly installed on the circumferential surface of the sliding rod 4. The connecting plate 7 is slidably installed on the inner wall of the support plate 3. The rotating plate 8 is rotatably installed on one side of the connecting plate 7 close to the first arc-shaped sleeve 6. The second arc-shaped sleeve 9 is fixedly penetrated through the inner and outer walls of the rotating plate 8. The grip rod 10 is slidably penetrated through the inner and outer walls of the sliding rod 4. The first spring 11 is arranged between the grip rod 10 and the sliding rod 4. The limiting short rod 12 is fixedly installed on the circumferential surface of the grip rod 10. The limiting short rod 12 is slidably penetrated through the circumferential surface of the sliding rod 4. The limiting long rod 13 is fixedly installed on the circumferential surface of the grip rod 10. The limiting long rod 13 is slidably penetrated through the inner and outer walls of the connecting plate 7. By opening the second arc-shaped sleeve 9, the first arc-shaped sleeve 6 and the second arc-shaped sleeve 9 do not need to move downward from the highest point of the cement column during fixation, avoiding unnecessary equipment movement in high-altitude operations and reducing potential safety hazards.

[0023] The surface of the rotating plate 8 close to the moving plate 5 is in contact with the inner wall of the support plate 3. A first volute spring is arranged between the rotating plate 8 and the connecting plate 7. By providing the first volute spring, the operator does not need to push the rotating plate 8 back to the initial position again, facilitating the operator to quickly fix the first arc-shaped sleeve 6 and the second arc-shaped sleeve 9.

[0024] The circumferential surface of the limiting short rod 12 is in contact with the inner wall of the limiting groove close to the moving plate 5, and the circumferential surface of the limiting long rod 13 is in contact with the inner wall of the limiting groove close to the connecting plate 7. By limiting both sides of the sliding rod 4, the stability is increased, and at the same time, the position of the sliding rod 4 can be quickly adjusted to adapt to the distance between the cement columns, reducing the time for multiple adjustments and effectively improving the efficiency of transformer installation.

[0025] An installation method for a transformer installation device for photovoltaic power generation, comprising the following steps: Step 1: Before the transformer is fixed on the transformer pole, first pull the rotating plate 8 to rotate away from the support plate 3, the surface where the rotating plate 8 moves and contacts the support plate 3 is separated, and at the same time, the rotation of the rotating plate 8 drives the second arc-shaped sleeve 9 to move away from the first arc-shaped sleeve 6; Step 2: After the second arc-shaped sleeve 9 moves to the specified position, move the first arc-shaped sleeve 6 to contact the circumferential surface of the cement column, close the rotating plate 8, the rotation of the rotating plate 8 drives the second arc-shaped sleeve 9 to reset to the initial position, and the second arc-shaped sleeve 9 contacts the circumferential surface of the cement column during the movement; Step 3: Fix the first arc-shaped sleeve 6 and the second arc-shaped sleeve 9 on the cement column with screws and nuts, and then repeat the above operation to fix the first arc-shaped sleeve 6 and the second arc-shaped sleeve 9 on the other side on another cement column; Step 4: After the transformer is fixed on the transformer pole, place the transformer on the top of the bottom plate 1, the transformer contacts the inner wall of the protection frame 2 during the movement, and then fix the transformer on the top of the bottom plate 1 with screws and nuts.

[0026] When this embodiment is working, before fixation, pull the rotating plate 8 to rotate away from the support plate 3, and the surface where the rotating plate 8 moves and contacts the support plate 3 is separated. The rotating plate 8 stretches the first scroll spring during rotation, and the first scroll spring deforms under the stretching force. At the same time, the rotation of the rotating plate 8 drives the second arc-shaped sleeve 9 to move away from the first arc-shaped sleeve 6. After the second arc-shaped sleeve 9 moves to the specified position, move the first arc-shaped sleeve 6 to contact the circumferential surface of the cement column, and release the rotating plate 8. The deformed first scroll spring restores itself under the action of its own elasticity, and the restoration of the first scroll spring drives the rotating plate 8 to move towards the support plate 3. The rotating plate 8 contacts the inner wall of the support plate 3 during movement. At the same time, the movement of the rotating plate 8 drives the second arc-shaped sleeve 9 to move towards the first arc-shaped sleeve 6, and the second arc-shaped sleeve 9 contacts the circumferential surface of the cement column during movement. Then, use screws and nuts to fix the first arc-shaped sleeve 6 and the second arc-shaped sleeve 9 on the cement column, and repeat the above operation to fix the first arc-shaped sleeve 6 and the second arc-shaped sleeve 9 on the other side to another cement column. After the fixation is completed, place the transformer on the top of the bottom plate 1. The transformer contacts the inner wall of the protection frame 2 during movement, and then use screws and nuts to fix the transformer on the top of the bottom plate 1. By opening the second arc-shaped sleeve 9, it is not necessary for the first arc-shaped sleeve 6 and the second arc-shaped sleeve 9 to move downward from the highest point of the cement column during fixation, avoiding unnecessary equipment movement during high-altitude operations and reducing potential safety hazards. When it is necessary to adjust the positions of the first arc-shaped sleeve 6 and the second arc-shaped sleeve 9, pull the grip rod 10 to move away from the sliding rod 4. The grip rod 10 squeezes the first spring 11 during movement, and the first spring 11 deforms under the squeezing force. At the same time, the movement of the grip rod 10 drives the limiting short rod 12 to move away from the moving plate 5, and the surface where the limiting short rod 12 contacts the limiting groove is separated. The movement of the grip rod 10 drives the limiting long rod 13 to move away from the moving plate 5, and the surface where the limiting long rod 13 contacts the limiting groove is separated, so that the limiting effect exerted by the limiting short rod 12 and the limiting long rod 13 on the sliding rod 4 is released simultaneously. Push the grip rod 10 to move away from the bottom plate 1. The movement of the grip rod 10 drives the sliding rod 4 to move away from the bottom plate 1. The movement of the sliding rod 4 drives the moving plate 5 to move away from the bottom plate 1. The movement of the moving plate 5 drives the first arc-shaped sleeve 6 to move away from the bottom plate 1. At the same time, the movement of the sliding rod 4 drives the connecting plate 7 to move away from the bottom plate 1. The movement of the connecting plate 7 drives the rotating plate 8 to move away from the bottom plate 1. The movement of the rotating plate 8 drives the second arc-shaped sleeve 9 to move away from the bottom plate 1. After the sliding rod 4 moves to the predetermined position, release the grip rod 10. The deformed first spring 11 restores itself and drives the grip rod 10 to move towards the sliding rod 4. The movement of the grip rod 10 drives the limiting short rod 12 and the limiting long rod 13 to move towards the moving plate 5. The limiting short rod 12 contacts the inner wall of the limiting groove during movement, and at the same time, the limiting long rod 13 contacts the inner wall of the limiting groove during movement, so that the movement of the sliding rod 4 is limited, and the stability is increased by limiting both sides of the sliding rod 4.At the same time, the position of the sliding rod 4 can be quickly adjusted to adapt to the distance between the cement columns, reducing the time for multiple adjustments and effectively improving the efficiency of transformer installation.

[0027] Please refer to Figures 1 - 9 , on the basis of the above-mentioned embodiments, in another embodiment of the present invention, it further includes a protection device and a deceleration device; the protection device includes a linkage frame 141, a carrying box 142, a telescopic plate 143, a second spring 144, a cylindrical rod 145, an L-shaped piece 146, a mounting block 147 and a rectangular piece 148. The linkage frame 141 is slidably installed on the surface of the support plate 3, the carrying box 142 is fixedly installed at one end of the linkage frame 141, the other end of the linkage frame 141 is fixedly connected to the connection plate 7, the telescopic plate 143 is slidably installed on the inner wall of the carrying box 142, the second spring 144 is arranged between the telescopic plate 143 and the carrying box 142, the cylindrical rod 145 is fixedly installed on the surface of the telescopic plate 143, the cylindrical rod 145 slidably penetrates through the inner and outer walls of the carrying box 142, the L-shaped piece 146 is fixedly installed on the inner wall of the carrying box 142, the mounting block 147 is fixedly installed on the inner wall of the telescopic plate 143, the rectangular piece 148 is rotatably installed on the inner wall of the mounting block 147, and a first arc surface is formed on the side of the telescopic plate 143 away from the second spring 144. The first arc surface contacts the rotating plate 8. When the rotating plate 8 is closed, the rectangular piece 148 and the L-shaped piece 146 do not trigger vibration, so that the first arc-shaped sleeve 6 that has already contacted the cement column will not be offset due to the influence of vibration, which not only improves the rationality of vibration but also ensures the accuracy of installation.

[0028] The L-shaped piece 146 itself has elasticity, and a second arc surface is formed at the end of the L-shaped piece 146 away from the carrying box 142. By forming the second arc surface, the wear generated when the L-shaped piece 146 contacts the rectangular piece 148 is reduced, which helps to extend the service life of the L-shaped piece 146.

[0029] A second scroll spring is arranged between the rectangular piece 148 and the mounting block 147, and the rectangular piece 148 contacts the inner wall of the mounting block 147. By applying continuous vibration to the rotating plate 8 during rotation through the telescopic plate 143, the smooth rotation of the rotating plate 8 during the installation process is effectively ensured, and the situation of jamming during the rotation of the rotating plate 8, which affects the efficiency of high-altitude operations, is avoided.

[0030] The speed reduction device includes a portal frame 151, a displacement plate 152, an elastic sheet 153, a contact rod 154, an adapter seat 155, a stop piece 156, an L-shaped block 157 and a baffle 158. The portal frame 151 is fixedly installed on the surface of the carrier box 142. The displacement plate 152 slides through the inner wall of the portal frame 151. The elastic sheet 153 is arranged between the displacement plate 152 and the portal frame 151. The contact rod 154 is fixedly installed on the surface of the displacement plate 152. The adapter seat 155 is fixedly installed on the inner wall of the portal frame 151. The stop piece 156 is rotatably installed on the inner wall of the adapter seat 155. The L-shaped block 157 is fixedly installed on the circumferential surface of the stop piece 156. The baffle 158 is fixedly installed on the inner wall of the adapter seat 155. The displacement plate 152 contacts the cylindrical rod 145. A third scroll spring is arranged between the stop piece 156 and the adapter seat 155. When the rotary plate 8 is opened, the stop piece 156 does not affect the movement of the contact rod 154, and the displacement plate 152 applies additional power to the cylindrical rod 145 to ensure that the telescopic plate 143 can smoothly move to the designated position when the second arc-shaped sleeve 9 is closed.

[0031] An arc surface three is formed on the side of the L-shaped block 157 close to the baffle 158. The arc surface three contacts the baffle 158. By applying intermittent resistance to the contact rod 154, the speed of the rotary plate 8 during reset is controlled to ensure that after the operator releases the rotary plate 8, the second arc-shaped sleeve 9 can be reset at a safe speed, thereby effectively improving the stability of installation.

[0032] When this embodiment is working, while the rotating plate 8 rotates, the pressure applied to the first arc surface is reduced, so that the deformed second spring 144 is restored under the action of its own elasticity. The restoration of the second spring 144 drives the telescopic plate 143 to move away from the carrier box 142. The movement of the telescopic plate 143 drives the cylindrical rod 145 to move away from the carrier box 142. At the same time, the movement of the telescopic plate 143 drives the mounting block 147 to move away from the carrier box 142. The movement of the mounting block 147 drives the rectangular piece 148 to move away from the carrier box 142. The rectangular piece 148 contacts the second arc surface during the movement. Since the rectangular piece 148 contacts the inner wall of the mounting block 147, the rotation of the rectangular piece 148 away from the connecting plate 7 is blocked. The rectangular piece 148 continues to move and squeezes the L-shaped piece 146. The L-shaped piece 146 deforms under the extrusion. The deformed L-shaped piece 146 stores energy under the action of its own elasticity. When the rectangular piece 148 separates from the second arc surface, the deformed L-shaped piece 146 quickly returns to its initial state. The L-shaped piece 146 collides with the second rectangular piece 148 during the restoration process to generate vibration. The L-shaped piece 146 repeats the above movement and collides with the third rectangular piece 148 to generate vibration, so that the L-shaped piece 146 intermittently collides with the rectangular piece 148 to generate continuous vibration. The rectangular piece 148 transmits the vibration to the moving telescopic plate 143, and the telescopic plate 143 then transmits the vibration to the rotating rotating plate 8 through the first arc surface, making the rotation of the rotating plate 8 smoother. After the telescopic plate 143 moves to the specified position, it stops moving. The rotating plate 8 continues to rotate and separates from the first arc surface. By applying continuous vibration to the rotating rotating plate 8 through the telescopic plate 143, the smoothness of the rotation of the rotating plate 8 during the installation process is effectively guaranteed, which is convenient for the operators in high-altitude operations to carry out efficient and stable installation work. When the first volute spring drives the rotating plate 8 to return to its original position, the rotating plate 8 and the first arc surface come into contact again, so that the rotation of the rotating plate 8 drives the telescopic plate 143 to move towards the carrier box 142. The telescopic plate 143 moves and squeezes the second spring 144. The second spring 144 deforms under the extrusion. The deformed second spring 144 exerts a reaction force on the telescopic plate 143. The telescopic plate 143 is affected by the reaction force and exerts an additional resistance on the rotating plate 8 during the reset. At the same time, the movement of the telescopic plate 143 drives the mounting block 147 to move towards the carrier box 142. The movement of the mounting block 147 drives the rectangular piece 148 to move towards the carrier box 142. The rectangular piece 148 contacts the second arc surface during the movement. The L-shaped piece 146 exerts an obstruction on the moving rectangular piece 148, making the rectangular piece 148 rotate away from the mounting block 147. The rectangular piece 148 moves and stretches the second volute spring. The second volute spring deforms under the stretching. The rectangular piece 148 continues to move and separates from the second arc surface. The restored deformed second volute spring drives the rectangular piece 148 to rotate to its initial position. By not triggering vibration when the rectangular piece 148 contacts the L-shaped piece 146 again, the first arc-shaped sleeve 6 that has already contacted the cement column will not be affected by the vibration and shift, which improves the rationality of the vibration.Also ensures the accuracy of installation; When the cylindrical rod 145 moves away from the displacement plate 152, the cylindrical rod 145 gradually reduces the thrust exerted on the displacement plate 152, causing the deformed elastic piece 153 to recover and drive the displacement plate 152 to move towards the cylindrical rod 145. During the movement of the displacement plate 152, it provides an additional thrust to the cylindrical rod 145. At the same time, the movement of the displacement plate 152 drives the contact rod 154 to move towards the cylindrical rod 145. The circumferential surface of the contact rod 154 contacts the side of the blocking piece 156 away from the telescopic plate 143 during the movement, causing the movement of the contact rod 154 to drive the blocking piece 156 to rotate towards the telescopic plate 143. The blocking piece 156 stretches the third scroll spring during the rotation, and the third scroll spring deforms under the stretching force. At the same time, the rotation of the blocking piece 156 drives the L-shaped block 157 to rotate away from the baffle 158, and the arc surface three separates from the baffle 158 during the movement. The contact rod 154 continues to move and separates from the blocking piece 156. The deformed third scroll spring recovers and drives the blocking piece 156 to rotate to the initial position. The rotation of the blocking piece 156 drives the L-shaped block 157 to move to the initial position, and the arc surface three contacts the baffle 158 again during the movement. By ensuring that the blocking piece 156 does not affect the movement of the contact rod 154, while the displacement plate 152 exerts an additional force on the cylindrical rod 145, it ensures that the telescopic plate 143 can smoothly move to the designated position when the second arc-shaped sleeve 9 is closed. When the cylindrical rod 145 moves towards the displacement plate 152, the movement of the cylindrical rod 145 drives the displacement plate 152 to move away from the elastic piece 153. The displacement plate 152 stretches the elastic piece 153 during the movement, and the elastic piece 153 deforms under the stretching force. The deformed elastic piece 153 exerts a reaction force on the displacement plate 152, causing the displacement plate 152 to exert an additional resistance on the cylindrical rod 145. At the same time, the movement of the displacement plate 152 drives the contact rod 154 to move away from the cylindrical rod 145. The circumferential surface of the contact rod 154 contacts the side of the blocking piece 156 close to the telescopic plate 143 during the movement. The rotation of the L-shaped block 157 towards the baffle 158 is blocked, causing the contact rod 154 to move and squeeze the blocking piece 156. The blocking piece 156 deforms under the extrusion force. The deformed blocking piece 156 exerts an additional resistance on the moving contact rod 154. The contact rod 154 continues to move and separates from the blocking piece 156. The deformed blocking piece 156 recovers under its own elasticity. The contact rod 154 contacts multiple blocking pieces 156 during the movement, causing the blocking pieces 156 to exert intermittent resistance on the contact rod 154. The speed of the movement of the contact rod 154 is slowed down by the intermittent resistance. By applying intermittent resistance to the contact rod 154 to control the speed of the reset of the rotating plate 8, it ensures that after the operator releases the rotating plate 8, the second arc-shaped sleeve 9 can be reset at a safe speed, thereby effectively improving the stability of the installation.
