Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic brackets, and in particular to an angle-adjustable photovoltaic bracket. Background Art

[0002] Photovoltaic panels are devices that convert sunlight into electrical energy through the photoelectric effect. They are composed of multiple photovoltaic cells. When sunlight shines on photovoltaic cells, photons are stimulated and absorbed, generating charges and currents. This process is also called photoelectric conversion. The output power of photovoltaic panels is affected by factors such as the intensity, angle, and spectrum of sunlight. When the angle of the photovoltaic panel is not appropriate, the power generation efficiency will be low. It can be seen that the adjustable angle of photovoltaic panels is very important. When doing field projects (such as building railways and water conservancy projects), workers need electricity for daily life, and do not need to lay a large number of them. The frequency of use is not high, and the power consumption is not large. Therefore, using photovoltaic panels to generate electricity and store it will be an economical choice.

[0003] Considering that photovoltaic panels are installed in areas with large sunlight contact areas during field projects, the complex environment during field operations may cause soft soil or land with more mud and sand, making it difficult to install photovoltaic panels. Although pouring cement on the ground can better fix the photovoltaic panels, it may increase the pressure on the ground, thereby causing land collapse. At the same time, the subsequent removal of cement is more troublesome, but if it is directly installed on the ground without being fixed, it may knock down the equipment when encountering rainy and snowy weather and soil erosion, causing equipment damage. The existing technology mostly requires manual adjustment when adjusting the angle, which takes a lot of time. In addition, since the construction period may sometimes be several years, the angle of the sun is different when the seasons change, and most of the existing technology has only one direction of angle adjustment, which will result in low power generation efficiency. The existing technology uses more mechanical structures, which will increase the loss of the mechanical structure, and needs to consume more energy to adjust the angle when in use. The photovoltaic power generation itself is not much, and when the mechanical structure increases, it will consume more energy. In addition, the existing technology is more troublesome to remove the photovoltaic panels, and it is not convenient to repair if they are damaged during use. Summary of the invention

[0004] The object of the present invention is to provide a photovoltaic bracket with adjustable angle to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is an angle-adjustable photovoltaic bracket, comprising a bracket seat, wherein the inner wall at the top of the bracket seat is rotatably connected to a rotating column, the top of the rotating column is fixedly connected to a rotating base plate, the top of the rotating base plate is fixedly connected to an angle adjustment mechanism, the inner wall of the bracket seat is slidably connected to a fixing mechanism, and there are two groups of fixing mechanisms.

[0006] The angle adjustment mechanism includes a driving motor, a motor fixing block is fixedly connected to the bottom of the driving motor, the bottom of the motor fixing block is fixedly connected to the top of the rotating base plate, the output shaft of the driving motor is fixedly connected to a power gear, the teeth of the power gear are meshed with a rack plate, the outer wall of the rack plate is slidably connected to a transmission shell, and there are two groups of transmission shells, one end of each group of transmission shells is fixedly connected to an adjustment shell, the interiors of the transmission shells and the adjustment shells are filled with water, the inner wall of the adjustment shell is slidably connected to an adjustment block, the inner wall of the adjustment block is rotatably connected to a base plate fixing block, and the top of the base plate fixing block is fixedly connected to a photovoltaic base plate.

[0007] With the above technical solution, the angle of the photovoltaic panel cannot be adjusted all the time during construction. When the position of the sun changes, a signal from the sunlight sensor will be received. The sunlight sensor will be used to understand whether the angle of the photovoltaic panel needs to be adjusted. When the angle needs to be adjusted, the motor will be started, and the motor will drive the power gear to rotate. During the rotation of the power gear, the rack plate will be pushed to move. When the rack plate moves, pressure will be applied to the water inside the transmission shell and the adjustment shell. At this time, the adjustment block can be pushed upward. At the same time, the movement of the rack plate on the other side will cause a cavity to be generated inside the transmission shell. The water will fill the cavity due to gravity. At this time, the inside of the adjustment shell is adjusted. A cavity will be generated inside the adjusting shell, and the cavity of the adjusting shell will reduce the internal air pressure. At this time, the external high air pressure will push the adjusting block to the low pressure area. At this time, the adjusting block will fill the cavity to balance the internal and external air pressures. At the same time, when a cavity is generated inside the adjusting shell, the gravity of the photovoltaic base plate will press the adjusting block down. At this time, the adjusting block will be assisted to fill the cavity of the adjusting shell. Compared with traditional equipment that uses more mechanical structures, the angle can be adjusted by pushing water to save energy consumption, reduce the loss caused by the mechanical structure, reduce the maintenance frequency, save costs, and the automatic angle adjustment also enables the photovoltaic panels to generate electricity at full power without manual labor.

[0008] Furthermore, each group of the fixing mechanism includes a lever, the outer wall of the bracket seat is provided with a through slot, the outer wall of the lever is slidably connected to the outer wall of the through slot, one end of the lever is fixedly connected to a traction block, the outer wall of the traction block is slidably connected to the inner wall of the bracket seat, the inner wall of the traction block is slidably connected to a sliding shaft, the outer wall of the sliding shaft is hinged with a traction rod, and there are two groups of traction rods, the inner wall of the bracket seat is slidably connected to a force-bearing block, and there are two groups of force-bearing blocks, and each group of traction rods is close to the force-bearing block. One end is hinged, the inner wall of each group of the force-bearing blocks is hinged with a hinge, and there are two groups of hinges, one side of each group of the hinges is hinged with a movable plate, and there are two groups of movable plates, the outer walls of every two groups of the movable plates are sealed with expansion rubber, and the force-bearing block, the movable plate and the expansion rubber surround an air cavity, the inner wall of the traction block is provided with an I-shaped groove, the inner wall of the I-shaped groove is slidably connected with an air guide tube, the bottom of the air guide tube is fixedly connected with a bellows, and one end of the bellows is fixedly connected to one side of the force-bearing block.

[0009] When the above technical solution is adopted, the environment is complex and the soil may be soft or the soil is sandy during field operations, which makes it difficult to install photovoltaic panels. Although pouring cement on the ground can better fix the photovoltaic panels, it may increase the pressure on the ground, thereby causing land collapse. At the same time, the subsequent removal of cement is more troublesome. However, if it is directly installed on the ground without being fixed, the equipment may be knocked down when encountering rainy and snowy weather and soil erosion, causing damage to the equipment. When installing the equipment, insert the bracket into the soil and press the lever downward. The lever will drive the traction block to move downward. When the traction block moves, it will push the traction rod downward, and the traction rod will push the force block outward. Since the original state of the expanded rubber is to wrap the movable plate in a fan shape (such as Figure 5As shown in the figure), when the force-bearing block has not moved outward, the movable plate will be subjected to the pressure of the expansion rubber itself to restore. When the force-bearing block moves outward, the force of the expansion rubber to restore will pull the movable plate outward and restore it to a fan-shaped state, so that the contact area with the soil can be increased. At the same time, when the traction block moves downward, the air inside the I-shaped groove will be pushed downward to the inside of the air guide tube. After the air enters the inside of the air guide tube, it will enter the inside of the air cavity along the bellows. When the inside of the air cavity is filled with air, the internal air pressure will increase. Since the force-bearing block and the movable plate are rigid, the excess air will flow to the expansion rubber and exert pressure on it, so that the expansion rubber is forced to expand outward. At this time, the contact area with the soil is further increased to avoid the equipment being knocked down and damaged when encountering soil erosion. And when dismantling the equipment, you only need to push the lever upward. The equipment can be pulled out of the ground, and the upward movement of the traction block will draw back the air inside the air cavity. At the same time, the air no longer exerts pressure on the expanded rubber, and the expanded rubber will return to its original state. When the traction block moves upward, it will also drive the traction rod to pull the force block inward. Since the movable plate is inclined, when the movable plate contacts the bracket seat, it will squeeze the movable plate and fold the upper and lower sides of the expanded rubber into a U-shape toward the movable plate and the cavity inside the expanded rubber until the movable plate completely enters the interior of the bracket seat and fits tightly with the bracket seat. At the same time, when the force block is retracted, the bracket seat will scrape off the soil on the outer wall of the force block, the movable plate and the expanded rubber, so as to facilitate the disassembly and assembly of the equipment. It can be quickly dismantled when changing the construction site, and an air pump can be set inside the traction block. When the internal air pressure is insufficient, air can be transported inward by the air pump to more conveniently fix the equipment.

[0010] Furthermore, a photovoltaic module is clamped on the top of the photovoltaic base plate, and there are multiple groups of photovoltaic modules. The outer wall of each group of photovoltaic modules is provided with a groove, and there are four groups of grooves. The inner walls of the grooves of every two groups of photovoltaic modules are clamped with expansion blocks, and there are multiple groups of expansion blocks. The outer wall of the photovoltaic base plate is provided with a drainage groove.

[0011] By adopting the above technical solution, when encountering rainy or snowy weather, the expansion block will absorb water and expand when it contacts water. After the expansion block expands, it will engage with the photovoltaic modules on both sides and completely fill the grooves of the photovoltaic modules. At this time, the fixation of the photovoltaic modules will be more stable. Since the photovoltaic base plate is inclined, when there is water inside the photovoltaic base plate, the water will be discharged through the drain groove to avoid internal water accumulation and increase in pressure. When the weather is clear, the expansion block will gradually drain or evaporate the internal water. At this time, the expansion block will return to its original state. At this time, the disassembly and assembly of the photovoltaic module will be more convenient, and the modular design of the photovoltaic module can be replaced more conveniently when it fails or is damaged.

[0012] Furthermore, the bottom of the rotating base plate is fixedly connected with spur teeth, the spur teeth are meshed with spur gears, one side of the spur gear is fixedly connected with a turntable, one side of the turntable is fixedly connected with a rotating handle, the outer wall of the rotating handle is rotatably connected to a handle jacket, the top wall of the bracket seat is fixedly connected with a fixing frame, and the inner wall of the fixing frame is rotatably connected to the outer wall of the spur gear.

[0013] By adopting the above technical solution, the direction of the sun will change when the seasons change. If the angle of the photovoltaic panel is incorrect or cannot be adjusted, the power generation efficiency will be low. When the angle needs to be adjusted, hold the rotating handle and turn the turntable. When the turntable rotates, it will drive the spur gear to rotate. Since the spur gear is engaged with the spur teeth at the bottom of the rotating base plate, when the spur gear rotates, it will drive the rotating base plate to rotate. At this time, the photovoltaic panel can be rotated at all angles, so that different angles can be adjusted even after installation. It can also be adjusted to the most suitable angle in different seasons to increase the power generation efficiency. If necessary, a motor can be set inside the spur gear, so that the photovoltaic panel can be adjusted without the need for personnel to be present.

[0014] Furthermore, a waterproof protective shell is fixedly connected to the top of the rotating base plate, the inner wall of the waterproof protective shell is slidably connected to the outer wall of the transmission shell, the top of the waterproof protective shell is fixedly connected to a signal antenna, the outer wall of the waterproof protective shell is fixedly connected to a status display screen, the outer wall of the waterproof protective shell is fixedly connected to a start button, and the outer wall of the waterproof protective shell is fixedly connected to a close button.

[0015] By adopting the above technical solution, since photovoltaic panels are usually set up in a flat area far away from buildings, it will be very difficult to adjust the angle of the photovoltaic panels if necessary. The setting of the signal antenna can be used to adjust the equipment through the remote network. When adjusting on-site, the status display screen can be turned on to observe the current power generation and other photovoltaic panel status, so as to better adjust the photovoltaic panels. When inspecting the equipment, the off button can be pressed. At this time, the circuit of the photovoltaic panel will be disconnected from the external circuit and the internal components will be powered off to protect the safety of the maintenance personnel. After the maintenance is completed, the start button can be pressed to resume the normal operation of the photovoltaic panel.

[0016] Furthermore, a support column is fixedly connected to the top of the waterproof protective shell, a support block is fixedly connected to the bottom of the photovoltaic base plate, and an outer wall of the support column is rotatably connected to an inner wall of the support block.

[0017] By adopting the above technical solution, the support column will support the support block when adjusting the angle of the photovoltaic panel, and the connection between the support block and the support column will be used as a fulcrum when adjusting the angle, so as to adjust the angle more accurately and protect the photovoltaic base plate from bending due to the angle adjustment.

[0018] Furthermore, a sliding groove is provided on the outer wall of the rack plate, a sliding block is provided on the inner wall of the transmission shell, and the inner wall of the sliding groove is slidably connected to the outer wall of the sliding block.

[0019] By adopting the above technical solution, the rack plate can be limited by setting the sliding groove and the sliding block, and the rack plate will not separate from the transmission shell when moving, so as to prevent the internal water from flowing out and affecting the accuracy of the angle adjustment.

[0020] Furthermore, sunlight sensors are fixed on both sides of the photovoltaic base plate.

[0021] By adopting the above technical solution, the position of the sun will change during the day. When the sunlight sensors on both sides of the photovoltaic base plate detect a significant light difference, the internal components can be controlled to adjust the angle of the photovoltaic panel, thereby obtaining higher power generation efficiency. Moreover, while traditional equipment is installed with the photovoltaic panel facing south, this equipment can be installed in the east-west direction, thereby obtaining better power generation efficiency.

[0022] The present invention has the following beneficial effects: 1. The angle of the photovoltaic panel cannot be adjusted all the time during construction. When the position of the sun changes, a signal from the sunlight sensor will be received. The sunlight sensor will be used to understand whether the angle of the photovoltaic panel needs to be adjusted. When the angle needs to be adjusted, the motor is started to drive the power gear to push the rack plate to move, and pressure is applied to the water inside the transmission shell and the adjustment shell. At this time, the adjustment block can be pushed upward to adjust the angle. Compared with traditional equipment that uses more mechanical structures, adjusting the angle by pushing water can save energy consumption, reduce the loss caused by the mechanical structure, reduce the maintenance frequency, and save costs.

[0023] 2. The direction of the sun will change with the change of seasons. If the angle of the photovoltaic panel is incorrect or cannot be adjusted, the power generation efficiency will be low. When the angle needs to be adjusted, hold the rotating handle and turn the turntable. When the turntable rotates, it will drive the spur gear to rotate. Since the spur gear is engaged with the spur teeth at the bottom of the rotating base plate, when the spur gear rotates, it will drive the rotating base plate to rotate. If necessary, a motor can be installed inside the spur gear, so that the photovoltaic panel can be adjusted without the need for personnel to be present.

[0024] 3. When encountering rainy and snowy weather, the expansion block of the present invention will absorb water and expand when it contacts water. After the expansion block expands, it will engage with the photovoltaic modules on both sides and completely fill the grooves of the photovoltaic modules. At this time, the fixation of the photovoltaic modules will be more stable. Since the photovoltaic base plate is inclined, when there is water inside the photovoltaic base plate, the water will be discharged through the drainage groove to avoid internal water accumulation and increase in pressure. When the weather is clear, the expansion block will gradually drain or evaporate the internal water. At this time, the expansion block will return to its original state. At this time, the disassembly and assembly of the photovoltaic module will be more convenient, and the modular design of the photovoltaic module can be more convenient to replace when it fails or is damaged.

[0025] 4. When working in the field, it is inevitable to encounter soft soil. If cement is poured into the ground, it may increase the pressure on the ground, resulting in land collapse. At the same time, the subsequent removal of cement is more troublesome. However, if it is installed directly on the ground, it may knock down the equipment when encountering soil erosion, causing damage to the equipment. When installing the equipment, insert the bracket into the soil and press the lever down. Since the original state of the expansion rubber is a fan-shaped wrapping of the movable plate (such as Figure 5 As shown in the figure), when the force-bearing block has not moved outward, the movable plate will be subjected to the pressure of the expansion rubber itself to restore itself. When the force-bearing block moves outward, the force of the expansion rubber to restore itself will pull the movable plate outward and restore it to a fan-shaped state. At this time, the contact area with the soil can be increased; when the air cavity is filled with air, the internal air pressure will increase, and the air pressure will exert pressure on the expansion rubber, causing the expansion rubber to expand outward under force. At this time, the contact area with the soil is further increased, which facilitates the disassembly and assembly of the equipment and can be quickly dismantled when the construction site is changed.

[0026] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 8 As shown, the present invention is an angle-adjustable photovoltaic bracket, comprising a rotating base plate 1, the top of the rotating base plate 1 is fixedly connected to an angle adjustment mechanism 2, the bottom of the angle adjustment mechanism 2 is fixedly connected to a rotating column, the outer wall of the rotating column is rotatably connected to a bracket seat 14, the interior of the bracket seat 14 is slidably connected to a fixing mechanism 3, and the fixing mechanism 3 has two groups.

[0032] The angle adjustment mechanism 2 includes a driving motor 21, the bottom of the driving motor 21 is fixedly connected to a motor fixing block, the bottom of the motor fixing block is fixedly connected to the top of the rotating base plate 1, the output shaft of the driving motor 21 is fixedly connected to a power gear 22, the teeth of the power gear 22 are meshed with a rack plate 23, the outer wall of the rack plate 23 is slidably connected to a transmission shell 24, and there are two groups of transmission shells 24, one end of each group of transmission shells 24 is fixedly connected to an adjustment shell 25, the interior of the transmission shell 24 and the adjustment shell 25 are filled with water, the inner wall of the adjustment shell 25 is slidably connected to an adjustment block 26, the inner wall of the adjustment block 26 is rotatably connected to a base plate fixing block, and the top of the base plate fixing block is fixedly connected to the photovoltaic base plate 11.

[0033] In this embodiment, the angle of the photovoltaic panel cannot be adjusted all the time during construction. When the position of the sun changes, a signal from the sunlight sensor will be received. The sunlight sensor will be used to understand whether the angle of the photovoltaic panel needs to be adjusted. When the angle needs to be adjusted, the motor is started to drive the power gear 22 to push the rack plate 23 to move, and pressure is applied to the water inside the transmission shell 24 and the adjustment shell 25. At this time, the adjustment block 26 can be pushed upward to achieve angle adjustment. Compared with traditional equipment that uses more mechanical structures, adjusting the angle by pushing water can save energy consumption, reduce the loss caused by the mechanical structure, reduce maintenance frequency, and save costs.

[0034] Specifically, each group of the fixing mechanism 3 includes a lever 31, the outer wall of the bracket seat 14 is provided with a through slot, the outer wall of the lever 31 is slidably connected to the outer wall of the through slot, one end of the lever 31 is fixedly connected to a traction block 32, the outer wall of the traction block 32 is slidably connected to the inner wall of the bracket seat 14, the inner wall of the traction block 32 is slidably connected to a sliding shaft, the outer wall of the sliding shaft is hinged with a traction rod 33, and there are two groups of traction rods 33, the inner wall of the bracket seat 14 is slidably connected to a force block 34, and there are two groups of force blocks 34, and each group of the traction rods 33 is close to the force block 34. One end is hinged, the inner wall of each group of the force-bearing blocks 34 is hinged with a hinge, and there are two groups of hinges, one side of each group of the hinges is hinged with a movable plate 37, and there are two groups of movable plates 37, the outer walls of every two groups of the movable plates 37 are sealed with expansion rubber 38, and the force-bearing block 34, the movable plate 37 and the expansion rubber 38 surround to form an air cavity, the inner wall of the traction block 32 is provided with an I-shaped groove, the inner wall of the I-shaped groove is slidably connected with an air guide tube 35, the bottom of the air guide tube 35 is fixedly connected with a bellows 36, and one end of the bellows 36 is fixedly connected to one side of the force-bearing block 34.

[0035] In this embodiment, when working in the field, the environment is complex and the soil may be soft or the soil is rich in mud and sand, which makes it difficult to install the photovoltaic panels. Although pouring cement into the ground can better fix the photovoltaic panels, it may increase the pressure on the ground, thereby causing land collapse. At the same time, the subsequent removal of cement is more troublesome. However, if it is directly installed on the ground without being fixed, the equipment may be knocked down when encountering rainy and snowy weather and soil erosion, causing damage to the equipment. When installing the equipment, the bracket seat 14 is inserted into the soil and the lever 31 is pressed downward. The lever 31 will drive the traction block 32 to move downward. When the traction block 32 moves, it will push the traction rod 33 to move downward, and the traction rod 33 will push the force block 34 to move outward. Since the original state of the expansion rubber 38 is a fan-shaped wrapping of the movable plate 37 (such as Figure 5 As shown in the figure, when the force-bearing block 34 has not yet moved outward, the movable plate 37 will be subjected to the pressure of the expansion rubber 38 itself returning to its original position. When the force-bearing block 34 moves outward, the force of the expansion rubber 38 returning to its original position will pull the movable plate 37 outward and restore it to a fan-shaped state, thereby increasing the contact area with the soil. At the same time, when the traction block 32 moves downward, the air inside the I-shaped groove will be pushed downward to the inside of the air guide tube 35. After the air enters the inside of the air guide tube 35, it will enter the inside of the air cavity along the bellows 36. When the inside of the air cavity is filled with air, the internal air pressure will increase. Since the force-bearing block 34 and the movable plate 37 are both rigid, the excess air will flow to the expansion rubber 38 and exert pressure on it, so that the expansion rubber 38 is forced to expand outward. At this time, the contact area with the soil is further increased to avoid the equipment being knocked down and damaged when encountering soil erosion. When dismantling the equipment, it is only necessary to push the lever 31 upward to remove the equipment from the ground When the traction block 32 is pulled out, the upward movement of the traction block 32 will draw back the air inside the air cavity, and the air will no longer exert pressure on the expansion rubber 38, and the expansion rubber 38 will return to its original state. When the traction block 32 moves upward, it will also drive the traction rod 33 to pull the force-bearing block 34 to move inward. Since the movable plate 37 is inclined, when the movable plate 37 contacts the bracket seat 14, it will squeeze the movable plate 37 and fold the upper and lower sides of the expansion rubber 38 into a U-shape toward the cavity inside the movable plate 37 and the expansion rubber 38 until the movable plate 37 completely enters the interior of the bracket seat 14 and fits tightly with the bracket seat 14. At the same time, when the force-bearing block 34 is retracted, the bracket seat 14 will scrape off the soil on the outer walls of the force-bearing block 34, the movable plate 37 and the expansion rubber 38, so as to facilitate the disassembly and assembly of the equipment. It can be quickly dismantled when changing the construction site, and an air pump can be set inside the traction block 32. When the internal air pressure is insufficient, air can be transported inward by the air pump to more conveniently fix the equipment.

[0036] Specifically, a photovoltaic module 12 is clamped on the top of the photovoltaic base plate 11, and there are multiple groups of photovoltaic modules 12. The outer wall of each group of photovoltaic modules 12 is provided with a groove, and there are four groups of grooves. The inner walls of the grooves of every two groups of photovoltaic modules 12 are clamped with expansion blocks 13, and there are multiple groups of expansion blocks 13. The outer wall of the photovoltaic base plate 11 is provided with a drainage groove.

[0037] In this embodiment, when encountering rainy or snowy weather, the expansion block 13 will absorb water and expand when it comes into contact with water. After the expansion block 13 expands, it will engage with the photovoltaic modules 12 on both sides and completely fill the grooves of the photovoltaic modules 12. At this time, the fixation of the photovoltaic modules 12 will be more stable. Since the photovoltaic base plate 11 is inclined, when there is water inside the photovoltaic base plate 11, the water will be discharged through the drainage groove to avoid internal water accumulation and increase in pressure. When the weather is clear, the expansion block 13 will gradually drain or evaporate the internal water. At this time, the expansion block 13 will return to its original state. At this time, the disassembly and assembly of the photovoltaic module 12 will be more convenient, and the modular design of the photovoltaic module 12 can be more convenient to replace in case of failure or damage.

[0038] Specifically, the bottom of the rotating base plate 1 is fixedly connected with spur teeth, which are meshed with spur gears 15, one side of the spur gear 15 is fixedly connected with a turntable, one side of the turntable is fixedly connected with a rotating handle, the outer wall of the rotating handle is rotatably connected to the handle jacket, the top wall of the bracket seat 14 is fixedly connected with a fixing frame, and the inner wall of the fixing frame is rotatably connected to the outer wall of the spur gear 15.

[0039] In this embodiment, the direction of the sun will change with the change of seasons. If the angle of the photovoltaic panel is incorrect or cannot be adjusted, the power generation efficiency will be reduced. When the angle needs to be adjusted, hold the rotating handle and turn the turntable. When the turntable rotates, it will drive the spur gear 15 to rotate. Since the spur gear 15 is engaged with the spur teeth at the bottom of the rotating base plate 1, when the spur gear 15 rotates, it will drive the rotating base plate 1 to rotate. At this time, the photovoltaic panel can be rotated at all angles, so that different angles can be adjusted even after installation. It can also be adjusted to the most suitable angle in different seasons to increase the power generation efficiency. If necessary, a motor can be set inside the spur gear 15, so that the photovoltaic panel can be adjusted without the need for personnel to be present.

[0040] Specifically, a waterproof protective shell 16 is fixedly connected to the top of the rotating base plate 1, the inner wall of the waterproof protective shell 16 is slidably connected to the outer wall of the transmission shell 24, the top of the waterproof protective shell 16 is fixedly connected to a signal antenna 17, the outer wall of the waterproof protective shell 16 is fixedly connected to a status display screen, the outer wall of the waterproof protective shell 16 is fixedly connected to a start button, and the outer wall of the waterproof protective shell 16 is fixedly connected to a close button.

[0041] In this embodiment, since photovoltaic panels are usually set up in a flat area far away from buildings, it will be very difficult to adjust the angle of the photovoltaic panels if necessary. The setting of the signal antenna 17 can adjust the equipment through a remote network. When adjusting on-site, the status display screen can be opened to observe the current power generation and other photovoltaic panel status, so as to better adjust the photovoltaic panels. When inspecting the equipment, the off button can be pressed. At this time, the circuit of the photovoltaic panel will be disconnected from the external circuit and the internal components will be powered off to protect the safety of the maintenance personnel. After the maintenance is completed, the start button can be pressed to restore the normal operation of the photovoltaic panel.

[0042] Specifically, the top of the waterproof protective shell 16 is fixedly connected to a support column 18, the bottom of the photovoltaic bottom plate 11 is fixedly connected to a support block, and the outer wall of the support column 18 is rotatably connected to the inner wall of the support block.

[0043] In this embodiment, the support column 18 will support the support block when the angle of the photovoltaic panel is adjusted. The connection between the support block and the support column 18 will also be used as a fulcrum when the angle is adjusted, so as to adjust the angle more accurately and protect the photovoltaic base plate 11 from bending due to the angle adjustment.

[0044] Specifically, a sliding groove is formed on the outer wall of the rack plate 23, a sliding block is formed on the inner wall of the transmission housing 24, and the inner wall of the sliding groove is slidably connected to the outer wall of the sliding block.

[0045] In this embodiment, the rack plate 23 can be limited by the setting of the sliding groove and the sliding block, and the rack plate 23 will not separate from the transmission shell 24 when moving, so as to prevent the internal water from flowing out and affecting the accuracy of the angle adjustment.

[0046] Specifically, sunlight sensors are fixed on both sides of the photovoltaic bottom plate 11 .

[0047] In this embodiment, the position of the sun changes throughout the day. When the sunlight sensors on both sides of the photovoltaic base plate 11 detect a significant light difference, the internal components can be controlled to adjust the angle of the photovoltaic panel, thereby obtaining higher power generation efficiency. Moreover, while traditional equipment is installed with the photovoltaic panel facing south, this equipment can be installed in the east-west direction, thereby obtaining better power generation efficiency.

[0048] When in use, first of all, it is inevitable to encounter soft soil during field operations. When photovoltaic panels are installed on mud or sandy land, pouring cement on the ground can better fix the photovoltaic panels, but it may cause increased pressure on the ground, thereby causing land collapse. At the same time, the subsequent shoveling of cement is more troublesome. However, if it is directly installed on the ground without being fixed, it may cause the equipment to be knocked down when encountering rainy and snowy weather and soil erosion, causing equipment damage. When the equipment is installed, the bracket seat 14 is inserted into the soil and the lever 31 is pressed downward. The lever 31 will drive the traction block 32 to move downward. When the traction block 32 moves, it will push the traction rod 33 to move downward, and the traction rod 33 will push the force block 34 to move outward. Since the original state of the expansion rubber 38 is a fan-shaped wrapping of the movable plate 37 (such as Figure 5 As shown in the figure, when the force block 34 has not moved outward, the movable plate 37 will be subjected to the pressure of the expansion rubber 38 itself to restore. When the force block 34 moves outward, the force of the expansion rubber 38 to restore the movable plate 37 will pull the movable plate 37 outward and restore it to the fan-shaped state, so that the contact area with the soil can be increased. At the same time, when the traction block 32 moves downward, the air inside the I-shaped groove will be pushed downward to the inside of the air guide tube 35. After the air enters the inside of the air guide tube 35, it will enter the inside of the air cavity along the bellows 36. When the inside is filled with air, the internal air pressure will increase. Since the force block 34 and the movable plate 37 are both rigid, the excess air will flow to the expansion rubber 38 and exert pressure on it, so that the expansion rubber 38 is forced to expand outward. At this time, the contact area with the soil is further increased to avoid the equipment being knocked down and damaged when encountering soil erosion. In addition, an air pump can be set inside the traction block 32. When the internal air pressure is insufficient, air can be transported inward by the air pump to fix the equipment more conveniently.

[0049] Secondly, the direction of the sun will change with the change of seasons. If the angle of the photovoltaic panel is not correct or cannot be adjusted, the power generation efficiency will be reduced. When the angle needs to be adjusted, hold the rotating handle and turn the turntable. When the turntable rotates, it will drive the spur gear 15 to rotate. Since the spur gear 15 is meshed with the spur teeth at the bottom of the rotating base plate 1, when the spur gear 15 rotates, it will drive the rotating base plate 1 to rotate, and if necessary, a motor can be set inside the spur gear 15, so that the photovoltaic panel can be adjusted without the presence of personnel; the position of the sun will change throughout the day, and the angle of the photovoltaic panel cannot be adjusted all the time during construction. When the sunlight sensors on both sides of the photovoltaic base plate 11 detect a significant light difference, the internal components can be controlled to adjust the angle of the photovoltaic panel. When the angle needs to be adjusted, the motor is started, and the motor drives the power gear 22 to rotate. During the rotation of the power gear 22, the rack plate 23 is pushed When the rack plate 23 moves, it will apply pressure to the water inside the transmission shell 24 and the adjustment shell 25. At this time, the adjustment block 26 can be pushed upward. At the same time, the movement of the rack plate 23 on the other side causes a cavity to be generated inside the transmission shell 24, and the water will fill the cavity due to gravity. At this time, a cavity will be generated inside the adjustment shell 25, and the cavity of the adjustment shell 25 will reduce the internal air pressure. At this time, the external high air pressure will push the adjustment block 26 to the low pressure area. At this time, the adjustment block 26 will fill the cavity to balance the internal and external air pressures. At the same time, when a cavity is generated inside the adjustment shell 25, the gravity of the photovoltaic base plate 11 will press the adjustment block 26 downward. At this time, the adjustment block 26 will be assisted to fill the cavity of the adjustment shell 25. At this time, the photovoltaic panel can be rotated at all angles, so that different angles can be adjusted even after installation, and it can be adjusted to the most suitable angle in different seasons to increase power generation efficiency.

[0050] Then, when encountering rainy or snowy weather, the expansion block 13 will absorb water and swell when it contacts water. After the expansion block 13 expands, it will engage with the photovoltaic modules 12 on both sides and completely fill the grooves of the photovoltaic modules 12. At this time, the fixation of the photovoltaic modules 12 will be more stable. Since the photovoltaic base plate 11 is inclined, when there is water inside the photovoltaic base plate 11, the water will be discharged through the drainage groove to avoid internal water accumulation and increase in pressure. When the weather is clear, the expansion block 13 will gradually drain or evaporate the internal water. At this time, the expansion block 13 will return to its original state. At this time, the disassembly and assembly of the photovoltaic module 12 will be more convenient, and the modular design of the photovoltaic module 12 can be more convenient to replace in case of failure or damage.

[0051] Finally, when dismantling the equipment, it is only necessary to pull the lever 31 upward to pull the equipment out of the ground. The upward movement of the traction block 32 will draw back the air inside the force block 34, and the air will no longer exert pressure on the expansion rubber 38, and the expansion rubber 38 will return to its original state. When the traction block 32 moves upward, it will also drive the traction rod 33 to pull the force block 34 to move inward. Since the movable plate 37 is inclined, when the movable plate 37 contacts the bracket seat 14, it will squeeze the movable plate 37 and fold the upper and lower sides of the expansion rubber 38 into a U-shape toward the cavity inside the movable plate 37 and the expansion rubber 38 until the movable plate 37 completely enters the interior of the bracket seat 14 and fits tightly with the bracket seat 14. At the same time, when the force block 34 is retracted, the bracket seat 14 will scrape off the soil on the outer walls of the force block 34, the movable plate 37 and the expansion rubber 38, which is convenient for the disassembly and assembly of the equipment and can be quickly dismantled when changing the construction site.
