Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic panels, and in particular to a tracking solar photovoltaic panel assembly. Background Art

[0002] Photovoltaic power generation is a clean way of generating electricity. In today's society where environmental protection is increasingly emphasized, photovoltaic power generation has received attention. Photovoltaic panel components are important equipment for photovoltaic power generation, which will generate direct current when exposed to sunlight.

[0003] When photovoltaic power generation is used, the efficiency of photovoltaic panels is related to the angle at which sunlight hits the photovoltaic panels. Therefore, there are a variety of devices in the prior art to achieve real-time tracking of the sun by photovoltaic panels to obtain the highest power generation efficiency. For example, the device shown in the patent number: CN106685330B, the patent name: Solar Tracking Power Generation Device provides a way to enable photovoltaic panels to track sunlight.

[0004] However, even though the tracking solar photovoltaic panel assemblies on the market can track the sun, they usually involve a certain amount of moving parts. When trying to apply these devices to large photovoltaic power generation fields in the northwest region, it is easy for dust, gravel and other debris carried by the local strong wind to invade the gaps in the moving parts, thereby damaging the reliability of these types of equipment, and then causing the equipment to track the sun often less than expected. Although this problem can be avoided by putting a plastic or cloth protective bag on the outside of the equipment, these protective bags are also easily damaged by long-term gravel impact, resulting in very limited protection effect.

[0005] To this end, a tracking solar photovoltaic panel assembly is proposed. Summary of the invention

[0006] The object of the present invention is to provide a tracking solar photovoltaic panel assembly to improve the ability of a movable structure in the tracking photovoltaic assembly to resist the invasion of external debris.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A tracking solar photovoltaic panel assembly comprises a frame for fixing on the ground, a rotating pedestal is rotatably mounted on the frame, a supporting column is fixedly mounted on the rotating pedestal, a rotating platform is arranged on the top of the supporting column, a photovoltaic panel body is fixedly mounted on the rotating platform, a protective device and a repair device are arranged on the rotating pedestal, and the repair device is used to repair the protective device.

[0009] Based on this setting, when the photovoltaic panels generate electricity during the day, the preset program in the photovoltaic power generation matrix can be used to control the rotating pedestal and the rotating platform to achieve rotation in two dimensions. After coupling these two rotation methods, the photovoltaic panels can always face the sun, thereby achieving highly efficient photovoltaic power generation.

[0010] In addition, the protective device can prevent gravel and other debris in the external environment from invading the area where the movable structure is located under the photovoltaic panel body, thereby maintaining a clean environment in the working area where the rotating platform and the rotating pedestal are located, thereby reducing the risk of environmental debris invading the gaps between the movable structures and improving the ability of the movable structure in the photovoltaic module to resist the invasion of external debris. Moreover, during the non-power generation period at night, the photovoltaic panel body is controlled by the program to return to a horizontal position. At this time, the repair device is activated to automatically detect and repair the damage on the protective device, thereby improving the reliability of the protective performance of the present invention and ensuring that the present invention can provide effective protection.

[0011] Preferably, the protective device includes two side panels symmetrically fixedly mounted on a rotating pedestal, and the two side panels are respectively located on both sides of the photovoltaic panel body, and an installation groove is opened on the side panel, a blocking cloth is arranged in the installation groove, and the top and bottom ends of the blocking cloth not located in the installation groove are respectively arranged on the bottom end of the photovoltaic panel body and the rotating pedestal; a replacement module is arranged on the rotating pedestal, and the replacement module periodically and automatically replaces the blocking cloth used for shielding.

[0012] Through this setting, when the protective device is working, first of all, the two side panels can directly shield the two sides of the photovoltaic panel body. At the same time, the planes where the two side panels are located are perpendicular to the rotation axis of the rotating pedestal. Therefore, even if the side panels are rigid panels, they will not hinder the modification of the photovoltaic panel body to change the tilt angle. The remaining two sides that are not blocked by the side panels can be blocked by the blocking cloth, thereby achieving the shielding of the four sides of the photovoltaic panel assembly as a whole, thereby reducing the risk of environmental debris invading the gap between the movable structures and improving the ability of the movable structure in the photovoltaic assembly to resist the invasion of external debris. In addition, the blocking cloth itself, as a component of the fabric category, has a soft characteristic, so the blocking cloth will not hinder the rotation of the photovoltaic panel body. During the night period, when the photovoltaic assembly stops generating electricity, the photovoltaic panel body is controlled by the program to return to the horizontal posture. At this time, the replacement module is first started, the blocking cloth that works during the daytime period is replaced, and a new blocking cloth is replaced. Then the repair device is started to detect and repair the damage on the replaced blocking cloth, thereby improving the reliability of the protective performance of the present invention and ensuring that the present invention can provide effective protection.

[0013] It is worth noting that, since the baffle cloth is arranged in the placement groove, a circular space is formed between the edge of the baffle cloth and the side wall of the placement groove, and the gap between the edge of the baffle cloth and the placement groove is narrow, so it is difficult for gravel to pass through the gap between the two. When the baffle cloth is deformed by the wind, the baffle cloth still changes shape in the placement groove, which means that the gap always exists, so the gravel blown by the wind is always difficult to invade the area where the movable components of the photovoltaic module are located, thereby reducing the risk of environmental debris invading the gap between the movable structures. On this basis, textile edge sealing can also be performed on the edge of the baffle cloth to increase the deformation resistance of the edge of the baffle cloth, thereby further reducing the risk of the gap between the baffle cloth and the placement groove being expanded by the wind, thereby improving the reliability of the present invention.

[0014] Preferably, the replacement module includes a driving motor fixedly mounted on the side panel, a driving roller 1 is fixedly mounted on the output end of the driving motor, a support is fixedly mounted on the bottom end of the photovoltaic panel body, a driving roller 2 is rotatably mounted on the support, and a transmission belt is jointly sleeved on the driving roller 1 and the driving roller 2; the baffle cloth is in the shape of an annular strip, and the baffle cloth is simultaneously sleeved on the driving roller 1 and the driving roller 2; a clamping roller 1 is rotatably mounted on the side panel, a clamping roller 2 is rotatably mounted on the support, the clamping roller 1 and the driving roller 1 cooperate with each other to clamp the baffle cloth, and the clamping roller 2 and the driving roller 2 cooperate with each other to clamp the baffle cloth.

[0015] Through this arrangement, the clamping roller 1 cooperates with the driving roller 1 to clamp the blocking cloth, and the clamping roller 2 cooperates with the driving roller 2 to clamp the blocking cloth. At this time, the blocking cloth is clamped, so even if the blocking cloth is not stretched straight on the driving roller 1 and the driving roller 2, there can be enough friction between the blocking cloth and the driving roller 1 and the driving roller 2 to allow the driving roller 1 and the driving roller 2 to drive the blocking cloth to move. Therefore, the design length of the blocking cloth can have a certain margin so that the blocking cloth will not hinder the rotation of the photovoltaic panel body.

[0016] When the present invention is in the night time period, the photovoltaic panel body is controlled by the program to return to the horizontal state, and then the driving motor is controlled by the program to start and drive the driving roller 1 and the driving roller 2 to rotate, so that the half of the blocking cloth that performs the shielding and protection operation during the daytime period will be moved from the outermost side of the present invention to the inner side of the present invention, and the other half of the blocking cloth that does not perform the shielding and protection operation during the daytime will, on the contrary, be moved from the inner side of the present invention to the outermost side of the present invention, thereby realizing the replacement of the blocking cloth that produces the shielding and protection function. The replaced blocking cloth is detected and repaired by the repair device, thereby ensuring that the blocking cloth of the present invention can play a practical protective role and improving the reliability of the protective performance of the present invention.

[0017] Preferably, the repair device includes a reserve box fixedly mounted on the side panel, a propulsion spring fixedly mounted in the reserve box, and a push plate fixedly mounted on the other end of the propulsion spring; patch sheets are arranged in the reserve box, a release port is opened at the bottom end of the reserve box, and the patch sheet is used to be adhered to the baffle cloth in an adhesive manner; a drive motor is fixedly mounted on the side panel, a feeding roller is fixedly mounted on the output end of the drive motor, and a plurality of hooks are evenly fixedly mounted on the feeding roller; a grating sensor is fixedly mounted on the side panel, the grating sensor is arranged opposite to the baffle cloth, and the grating sensor is electrically connected to the drive motor and the drive motor.

[0018] With this arrangement, when the baffle is replaced with the operation of the drive motor, the grating sensor will continue to detect the replaced half of the baffle. If there is a break on this part of the baffle, the laser of the grating sensor can pass through the break, thereby triggering the grating sensor and sending an electrical signal. Subsequently, the control program controls the drive motor to start, so that the feeding roller rotates. At this time, the bottom side of one of the patch sheets pre-stored in the storage box protrudes from the release port, and at the same time, the patch sheet is pressed to the bottom of the storage box under the elastic force of the propulsion spring and will not fall down. Therefore, the hook on the rotating feeding roller will hook the bottom side of the patch sheet protruding from the release port during the movement, and pull it out of the storage box during the subsequent movement. When the patch sheet is about to be completely pulled out of the storage box, the rotation of the feeding roller causes another hook to hook into the side of the patch sheet that leaves the storage box, thereby the patch sheet is grabbed by the feeding roller, and the patch sheet is attached to the cylindrical surface of the feeding roller. Afterwards, the filling roller continues to move so that the repair piece is in contact with the baffle cloth. At this time, the repair piece is attached to the baffle cloth by bonding, thereby repairing the damaged part of the baffle cloth.

[0019] Among them, the bonding method can be the following two methods: first, the patch piece is preset with a Velcro bristle surface, that is, a side of the Velcro with a large number of harder and fine hooks, which is hooked into the cloth surface of the baffle through the bristle surface to achieve adhesive repair; second, solid glue is pre-installed on the wall surface on one side of the storage box where the patch piece is squeezed by the propulsion spring, so when the patch piece is pulled out of the storage box, it will be stained with a certain amount of glue, and then the adhesive force of this part of the glue is used to stick the patch piece to the cloth surface of the baffle.

[0020] Therefore, the present invention can detect and repair the damage on the replaced baffle cloth, thereby improving the reliability of the protective performance of the present invention, while reducing the number of inspections required for the present invention, extending the service life of the present invention, and saving maintenance costs.

[0021] Preferably, the patch includes a cloth layer and a hot melt adhesive layer, a heating cylinder is rotatably mounted on the side plate, a resistance wire is arranged inside the heating cylinder, and the resistance wire is electrically connected to the grating sensor.

[0022] Through this arrangement, the hot melt adhesive can be used to show adhesive force only in the molten state, so that the patch sheet does not show adhesiveness at room temperature, so that the patch sheet is easier to be pulled out of the storage box by the claws, and no additional resistance is caused by the stickiness of the patch sheet. In addition, the arrangement of the hot melt adhesive layer allows the overall structure of the patch sheet to have a certain strength, so when the claw tries to hook into the patch sheet, the patch sheet is easier to be hooked into by the claw, rather than deforming due to softness to avoid the claw, thereby improving the reliability of the present invention.

[0023] In addition, when the grating sensor detects a tear on the baffle cloth, the electrical signal it sends causes the control system to start the resistance wire in the heating cylinder, so that the resistance wire starts to heat up. Subsequently, when the filling roller sticks the patch to the baffle cloth, the heating cylinder and the filling roller squeeze the baffle cloth and the patch at the same time. At this time, the hot melt adhesive layer on the patch fits, presses and heats the baffle cloth, so the hot melt adhesive melts and adheres to the baffle cloth, thereby completing the bonding between the patch and the baffle cloth, that is, completing the repair work of the baffle cloth, improving the reliability of the protective performance of the present invention, and reducing maintenance costs.

[0024] It is worth noting that in order to improve the heating efficiency of the hot melt adhesive layer so that the hot melt adhesive layer can be melted quickly in a short time to improve the repair efficiency, the hot melt adhesive can be pre-made into fine particles and then spread on the cloth layer of the repair piece, and then slightly heated to make these particles adhere to the cloth layer. In this way, the hot melt adhesive layer will be able to obtain a larger overall surface area, so that the hot melt adhesive layer can have a larger heating area, which is more conducive to the rapid melting of the hot melt adhesive layer.

[0025] Preferably, a protrusion is provided on the cloth layer, no hot melt adhesive layer is provided on the protrusion, and the end of the hook claw is serrated.

[0026] By providing the protrusion, the patch will have a portion of fabric that is not bonded with the hot melt adhesive layer, so when the hook claw tries to hook into the patch, it can hook into the protrusion, thereby avoiding the hook claw's hooking action from being resisted by the hot melt adhesive layer, thereby making it easier for the hook claw to hook into the patch, improving the reliability of the present invention. On this basis, a serration portion is provided on the end of the hook claw to form a serration shape, so that the end of the hook claw has a plurality of fine tips, so that the hook claw is easier to hook into the weaving gap of the fabric layer.

[0027] In addition, the protrusion is not used as the main repair material part during bonding, so even if it is damaged, it will not affect the repair effect of the patch. Therefore, after the patch is attached to the baffle, the hook can be allowed to tear the protrusion under the mechanical force of the driving motor, so that the hook can be smoothly removed from the patch, ensuring the movement stability of the present invention.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. By setting up a protective device, it is possible to prevent gravel and other debris in the external environment from invading the area where the movable structure is located under the photovoltaic panel, so that the working area where the rotating platform and the rotating pedestal are located always maintains a clean environment, and improves the ability of the movable structure in the photovoltaic module to resist the invasion of external debris. By setting up a replacement module, the blocking cloth that works during the daytime can be replaced and replaced with a new one, thereby ensuring that the blocking cloth can provide effective shielding and protection effects.

[0030] 2. By setting up a repair device, at night, when the photovoltaic module is not generating electricity, the photovoltaic panel body is controlled by the program to return to a horizontal position. At this time, the repair device is started and automatically detects damage on the barrier cloth. If there is damage, the control program controls the filling roller to rotate. Then, the claws on the rotating filling roller will hook the bottom side of the repair piece protruding from the release port during the movement and pull it out of the reserve box. Then, the repair piece is attached to the barrier cloth and the repair piece is attached to the barrier cloth by bonding, so as to repair the damaged part of the barrier cloth, thereby ensuring the reliability of the protective performance of the barrier cloth.

[0031] 3. By providing a hot melt adhesive layer, a cloth layer and a heating cylinder, the hot melt adhesive can be used to show adhesive force only in a molten state, so that the patch sheet does not show adhesiveness at room temperature, so that the patch sheet is easier to be pulled out of the storage box by the claws, and no additional resistance is caused by the stickiness of the patch sheet. In addition, the provision of the hot melt adhesive layer allows the overall structure of the patch sheet to have a certain strength, so when the claw tries to hook into the patch sheet, the patch sheet is more easily hooked by the claw, rather than deforming due to softness to avoid the claw, thereby improving the reliability of the present invention.

DETAILED DESCRIPTION

[0042] The following content will use the drawings listed in the aforementioned "Description of Drawings" section to clearly explain the specific implementation methods of the present invention, in the hope that readers can have a more complete and objective understanding of the working principle of the present invention and the corresponding technical effects.

[0043] like Figures 1 to 9 As shown, a specific implementation of the present invention is demonstrated. Among them, several points need to be explained in advance: first, the rotating platform 3 and the rotating base 2 are both rotating mechanisms driven by servo motors. There are already mature implementations in the prior art, so they will not be repeated in the following content of this article; second, in order to fill the inevitable matching gaps between the various structures of the present invention, soft brushes 64 can be arranged in these gaps according to actual design needs to cover these gaps, and at the same time, the soft and deformable nature of the soft brush 64 is utilized so that the movement between the components related to these gaps will not be hindered. In particular, if the brush 64 is set in the gap between the cloth 7 and its adjacent components, the brush 64 can also clean the gravel attached to the cloth 7, thereby ensuring the cleanliness of the cloth 7, so as to prevent the gravel from entering the interior of the present invention with the movement of the cloth 7; third, in order to facilitate the arrangement of the cloth 7 in the placement groove 61, the driving roller 1 63 is also arranged in the placement groove 61. For details, please refer to Figure 3Correspondingly, in order to enable the heating cylinder 67 to cooperate with the feeding roller 65 to clamp the cloth 7, the heating cylinder 67 is also arranged in the placement groove 61. Similarly, the grating sensor 68 is also arranged in the placement groove 61. Fourthly, see Figure 1 and Figure 3 As shown, the length of the cloth 7 should be set with a certain margin so that the photovoltaic panel body 4 can have sufficient space for movement when moving. The figure is only for illustration. When the present invention is applied, the selection of the length margin of the cloth 7 should be appropriately selected according to the actual working conditions and design; fifth, the transmission belt 632 is arranged on the side of the side plate 6 close to the external environment. At the same time, one end of the driving roller 1 63 and the driving roller 2 62 are extended from the side of the side plate 6, so the transmission belt 632 is sleeved on the end of the driving roller 1 63 and the driving roller 2 62 respectively extending from the side plate 6 to realize belt transmission. At the same time, in order to prevent the influence of the external environment on the belt transmission, a protective cover 633 is provided on the outer cover of the transmission belt 632, and the motor is fixedly installed on the outside of the protective cover 633 to avoid interference with components; sixth, see Figure 1 Although the top of the side panel 6 is higher than the top surface of the photovoltaic panel body 4, during use, the rotating base 2 will rotate under program control to make the photovoltaic panel body 4 face the sunlight. Therefore, the side panel 6 will not have an inclined projection on the photovoltaic panel, so it will not affect the power generation performance of the photovoltaic panel.

[0044] When the present invention is installed, first take out the frame 1 for fixing on the ground, the frame 1 has a rotating base 2 rotatably mounted on it, the rotating base 2 has a supporting column 5 fixedly mounted on it, a rotating platform 3 is arranged at the top of the supporting column 5, a photovoltaic panel 4 is fixedly mounted on the rotating platform 3, a protective device and a repairing device are arranged on the rotating base 2, and the repairing device is used to repair the protective device.

[0045] Among them, the protective device includes two side panels 6 symmetrically fixedly installed on the rotating base 2, and the two side panels 6 are respectively located on both sides of the photovoltaic panel body 4, and a placement groove 61 is opened on the side panel 6, and a blocking cloth 7 is arranged in the placement groove 61. The top and bottom ends of the blocking cloth 7 not located in the placement groove 61 are respectively arranged on the bottom end of the photovoltaic panel body 4 and the rotating base 2; a replacement module is arranged on the rotating base 2, and the replacement module periodically and automatically replaces the blocking cloth 7 used for shielding.

[0046] Specifically, the replacement module includes a driving motor fixedly mounted on the side panel 6, a driving roller 1 63 is fixedly mounted on the output end of the driving motor, a support 621 is fixedly mounted on the bottom end of the photovoltaic panel body 4, a driving roller 2 62 is rotatably mounted on the support 621, and a transmission belt 632 is jointly sleeved on the driving roller 1 63 and the driving roller 2 62; the baffle cloth 7 is in the shape of an annular strip, and the baffle cloth 7 is simultaneously sleeved on the driving roller 1 63 and the driving roller 2 62; a clamping roller 1 631 is rotatably mounted on the side panel 6, and a clamping roller 2 622 is rotatably mounted on the support 621, the clamping roller 1 631 and the driving roller 1 63 cooperate with each other to clamp the baffle cloth 7, and the clamping roller 2 622 and the driving roller 2 62 cooperate with each other to clamp the baffle cloth 7.

[0047] The repair device includes a reserve box 66 fixedly mounted on the side plate 6, a propulsion spring 661 fixedly mounted in the reserve box 66, and a push plate 662 fixedly mounted on the other end of the propulsion spring 661; patch sheets 663 are arranged in the reserve box 66, and a release port 666 is provided at the bottom of the reserve box 66, and the patch sheets 663 are used to be attached to the baffle cloth 7 by bonding; a driving motor is fixedly mounted on the side plate 6, and a feeding roller 65 is fixedly mounted on the output end of the driving motor, and a plurality of hooks 651 are evenly fixedly mounted on the feeding roller 65; a grating sensor 68 is fixedly mounted on the side plate 6, and the grating sensor 68 is arranged directly opposite to the baffle cloth 7, and the grating sensor 68 is electrically connected to the driving motor and the driving motor. Among them, the patch sheet 663 includes a cloth layer 664 and a hot melt adhesive layer 665, and a heating cylinder 67 is rotatably mounted on the side plate 6, and a resistance wire 71 is arranged in the heating cylinder 67, and the resistance wire 71 is electrically connected to the grating sensor 68.

[0048] In addition, a protrusion 6641 is provided on the cloth layer 664, and no hot melt adhesive layer 665 is provided on the protrusion 6641. The end of the hook 651 is serrated. The hot melt adhesive layer 665 is composed of a plurality of hot melt adhesive particles evenly laid on the cloth layer 664. An edge sealing portion 72 is provided at the edge of the retaining cloth 7, and the edge sealing portion 72 is made in a woven manner.

[0049] When the present invention generates electricity during the day, the preset program in the photovoltaic power generation matrix can be used to control the rotating pedestal 2 and the rotating platform 3 to achieve rotation in two dimensions. After the two rotation modes are coupled, the photovoltaic panel 4 can always face the sun, thereby achieving efficient photovoltaic power generation.

[0050] In addition, the protective device can prevent gravel and other debris in the external environment from invading the area where the movable structure is located under the photovoltaic panel body 4, thereby maintaining a clean environment in the working area where the rotating platform 3 and the rotating pedestal 2 are located, thereby reducing the risk of environmental debris invading the gap between the movable structures and improving the ability of the movable structure in the photovoltaic module to resist the invasion of external debris. Moreover, during the non-power generation period at night, the photovoltaic panel body 4 is controlled by the program to return to the horizontal position. At this time, the repair device is started to automatically detect and repair the damage on the protective device, thereby improving the reliability of the protective performance of the present invention and ensuring that the present invention can provide effective protection.

[0051] When the protective device is working, firstly, the two side panels 6 can directly shield the two sides of the photovoltaic panel body 4. At the same time, the planes where the two side panels 6 are located are perpendicular to the rotation axis of the rotating pedestal 2. Therefore, even if the side panels 6 are rigid panels, they will not hinder the photovoltaic panel body 4 from changing the tilt angle. The remaining two sides that are not blocked by the side panels 6 can be blocked by the blocking cloth 7, thereby achieving the shielding of the four sides of the photovoltaic panel assembly as a whole, thereby reducing the risk of environmental debris invading the gap between the movable structures and improving the ability of the movable structure in the photovoltaic assembly to resist the invasion of external debris. In addition, as a component of the fabric category, the blocking cloth 7 itself has a soft characteristic, so the blocking cloth 7 will not hinder the rotation of the photovoltaic panel body 4. During the night period, when the photovoltaic components stop generating electricity, the photovoltaic panel body 4 is controlled by the program to return to the horizontal position. At this time, the replacement module is started first to replace the baffle cloth 7 that was working during the daytime, and then replace it with a new baffle cloth 7. Then the repair device is started to detect and repair the damage on the replaced baffle cloth 7, thereby improving the reliability of the protective performance of the present invention and ensuring that the present invention can provide effective protection.

[0052] When the present invention is in the night time period, the photovoltaic panel body 4 is controlled by the program to return to the horizontal state, and then the driving motor is controlled by the program to start and drive the driving roller 1 63 and the driving roller 2 62 to rotate, so that the half of the blocking cloth 7 that performs the shielding and protection operation during the daytime period will be moved from the outermost side of the present invention to the inner side of the present invention, and the other half of the blocking cloth 7 that does not perform the shielding and protection operation during the daytime will, on the contrary, be moved from the inner side of the present invention to the outermost side of the present invention, thereby realizing the replacement of the blocking cloth 7 that produces the shielding and protection function. The replaced blocking cloth 7 is detected and repaired by the repair device, thereby ensuring that the blocking cloth 7 of the present invention can play a practical protective role and improving the reliability of the protective performance of the present invention.

[0053] When the cloth 7 is replaced with the operation of the driving motor, the grating sensor 68 will continue to detect the replaced half of the cloth 7. If there is a break in this part of the cloth 7, the laser of the grating sensor 68 can pass through the break, thereby triggering the grating sensor 68 and sending an electrical signal. Subsequently, the control program controls the driving motor to start, so that the feeding roller 65 rotates. At the same time, the resistance wire 71 in the heating cylinder 67 is also started, so that the resistance wire 71 starts to heat up.

[0054] At this time, see Figure 5 , the bottom side of one of the patch sheets 663 pre-stored in the reserve box 66 sticks out from the release port 666, and at the same time, the patch sheet 663 is pressed to the bottom of the reserve box 66 by the elastic force of the push spring 661 and does not fall down. Therefore, the hook 651 on the rotating feeding roller 65 will hook the bottom side of the patch sheet 663 sticking out from the release port 666 during the movement, and pull it out of the reserve box 66 in the subsequent movement. When the patch sheet 663 is about to be completely pulled out of the reserve box 66, the rotation of the feeding roller 65 causes another hook 651 to hook into the side of the patch sheet 663 that is leaving the reserve box 66, so that the patch sheet 663 is grabbed by the feeding roller 65, and the patch sheet 663 is attached to the cylindrical surface of the feeding roller 65.

[0055] Afterwards, refer to Figure 7 As shown, the filling roller 65 continues to move so that the repair piece 663 is in contact with the baffle cloth 7. At this time, the heating cylinder 67 and the filling roller 65 squeeze the baffle cloth 7 and the repair piece 663 at the same time, and the hot melt adhesive layer 665 on the repair piece 663 is in contact with the baffle cloth 7, pressed and heated, so that the hot melt adhesive melts and adheres to the baffle cloth 7, thereby completing the bonding between the repair piece 663 and the baffle cloth 7, that is, completing the repair work of the baffle cloth 7, thereby improving the reliability of the protective performance of the present invention and reducing the maintenance cost.

[0056] Therefore, the present invention can detect and repair the damage on the replaced baffle cloth 7, thereby improving the reliability of the protective performance of the present invention, while reducing the number of inspections required for the present invention, extending the service life of the present invention, and saving maintenance costs.

[0057] It should be emphasized that although this embodiment only shows a tracking photovoltaic panel assembly composed of a rotating base 2 and a rotating platform 3, the application scenario of the present invention is not limited to this type of equipment, but can be applied to various photovoltaic panel assemblies that use movable structures to achieve automatic tracking of the sun.

[0058] Based on the contents recorded in the above text, although the beneficial effects of the present invention have been elaborated in detail and corresponding specific implementation methods have been provided for this purpose, ordinary technicians in this field can still make conventional substitutions, deformations, etc. based on the given technical solutions without creative labor to achieve the same technical effects, provided that they fully understand the working principle of the present invention, but such changes should not be considered to exceed the scope of the present invention. Specifically, the scope of the present invention is defined by the attached claims and their equivalents.
