Description

Technical Field

[0001] This invention relates to the field of photovoltaic module installation equipment technology, and specifically to a photovoltaic module security device and its operation method. Background Technology

[0002] Photovoltaic power generation is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy.

[0003] Photovoltaic power generation mainly includes centralized and distributed systems. Distributed systems mainly refer to the installation of photovoltaic power generation devices in small areas such as residential rooftops and factory rooftops, and the installation method is mainly manual. Centralized systems involve the large-area deployment of photovoltaic modules, and manual installation is inefficient and no longer applicable. Therefore, the installation of centralized photovoltaic modules is usually automated.

[0004] One step in the automated installation of photovoltaic (PV) modules is to lay each vertically arranged PV module down to a horizontal position. The equipment used includes a flow rack transport mechanism and a laying mechanism. When the PV modules are transported from the flow rack to the laying mechanism, a safety device is needed to secure them and prevent them from tipping over. A rotating feeding mechanism is used to lay the PV modules down to a horizontal position. Specifically, a separation mechanism separates the first PV module from the modules following it, placing the first PV module in a gripping and rotating position. The rotating feeding mechanism then grips the first PV module at the designated position and rotates, aligning the gripped PV module parallel to the steel strand below. Finally, the rotating feeding mechanism releases the first PV module, allowing it to fall onto the steel strand for transport.

[0005] Therefore, the safety device, as a component connecting the flow rack transport mechanism and the rotating unloading mechanism, not only transports the photovoltaic modules conveyed by the flow rack transport mechanism to the clamping and rotating position, but also prevents the photovoltaic modules from tipping over. Summary of the Invention

[0006] The purpose of this invention is to provide a photovoltaic module safety device and operating method, which can limit the photovoltaic modules transported to the tilting mechanism to prevent the photovoltaic modules from tipping over, and enable the photovoltaic modules to be picked up one by one by the rotating feeding mechanism and tilted to a horizontal position.

[0007] This invention is achieved through the following technical solution:

[0008] A photovoltaic module security device includes an anti-tipping frame, an upper baffle, and a rotation limiting component;

[0009] The anti-tipping frame has a central through-hole for the photovoltaic module to pass through, and the bottom of the anti-tipping frame is used to connect to a smooth transport mechanism.

[0010] The upper baffle is located on the front side of the top of the anti-tipping frame, and the upper baffle is used to block the upper part of the photovoltaic module passing through the anti-tipping frame;

[0011] The rotation limiting component includes a rotating part and a blocking part. One end of the rotating part is connected to the anti-tipping frame, and the other end is connected to the blocking part. The blocking part is located on the front side of the upper baffle. There is a gap between the blocking part and the upper baffle in the photovoltaic module transportation direction. This gap can accommodate at least one photovoltaic module. When the blocking part rotates to the vertical position, it blocks the upper part of the photovoltaic module. When the blocking part rotates to the horizontal position, it allows the photovoltaic module to pass through.

[0012] In this invention, "front side" refers to the area at the forefront of the photovoltaic module's transport direction. The blocking part of this invention rotates via a rotating part. The term "first photovoltaic module" is relative and does not specifically refer to any particular photovoltaic module; it refers to the foremost photovoltaic module located at the end of the flow transport mechanism, specifically the one whose upper and lower parts are blocked by the upper baffle and the baffle at the end of the transport mechanism, respectively.

[0013] In this invention, when photovoltaic modules are transported to the front of the flow transport mechanism, the lower part of the photovoltaic module is blocked by a baffle at the end of the flow transport mechanism, and the upper part is blocked by an upper baffle on the security device. This achieves positioning and blocking of the photovoltaic modules located at the security device. At this time, a batch of photovoltaic modules are continuously and tightly attached together. However, flipping photovoltaic modules requires flipping them one by one. Therefore, before flipping, the first photovoltaic module needs to be separated from the subsequent photovoltaic modules. After separation, the first photovoltaic module loses the obstruction of the baffle at the end of the flow transport mechanism and the upper baffle, and enters the gap between the blocking part and the upper baffle. At this time, the first photovoltaic module is blocked by the blocking part, achieving separation and blocking of the photovoltaic module. When the blocking part rotates to the horizontal position, the photovoltaic module is allowed to pass through. That is, the photovoltaic module placed in the gap between the blocking part and the upper baffle loses any obstruction and can be clamped by the rotating feeding mechanism and laid down horizontally.

[0014] Thus, the present invention can limit the photovoltaic modules transported to the tilting mechanism, preventing the photovoltaic modules from tipping over, and allowing the photovoltaic modules to be picked up one by one by the rotating unloading mechanism and tilted to a horizontal position.

[0015] Furthermore, the upper baffle is provided with a first waist hole, and the upper baffle is connected to the top of the anti-tipping frame by bolt fastening through the first waist hole. The vertical displacement of the upper baffle is achieved by adjusting the position of the bolt in the first waist hole.

[0016] Furthermore, a downward-pressing telescopic assembly is provided on the rear side of the upper baffle; the downward-pressing telescopic assembly is used to press the first photovoltaic module blocked by the rear side of the upper baffle into the gap between the front side of the upper baffle and the blocking part. The function of the downward-pressing telescopic assembly is to press the first photovoltaic module out of the upper baffle to prevent the first photovoltaic module from being squeezed by the upper baffle and the second photovoltaic module panel and thus unable to separate.

[0017] Furthermore, mounting blocks are provided on both sides of the top of the anti-tipping frame; the upper baffle and the rotation limiting assembly are both mounted on the mounting blocks.

[0018] Furthermore, guide plates are provided on both sides of the anti-tipping frame, which are used to guide the photovoltaic modules conveyed on the smooth transport mechanism through the anti-tipping frame.

[0019] The guide plate described in this invention can not only guide the photovoltaic modules conveyed on the flow transport mechanism through the anti-tipping frame, but also limit the two sides of the photovoltaic modules at the end of the flow transport mechanism to prevent the photovoltaic modules from tipping over from both sides of the transport direction of the flow transport mechanism.

[0020] Furthermore, the guide plate includes an inlet section and a fixed section;

[0021] The fixing section is installed on the inner wall of the anti-tipping frame, and the length direction of the fixing section is consistent with the transportation direction of the photovoltaic module.

[0022] One end of the inlet section is connected to the fixed section, and the inlet section forms an angle with the transportation direction of the photovoltaic module, so that the horizontal distance between the guide plates on both sides of the anti-tipping frame gradually decreases from one end of the inlet section to the other end at the fixed section.

[0023] The guide plate has a funnel-shaped entrance, which not only facilitates guiding the photovoltaic modules to the security device, but also ensures that photovoltaic modules that have been offset too much at the rear end can be gradually guided to the appropriate position.

[0024] Furthermore, the guide plate is installed on the inside of the anti-tipping frame via a fixing plate;

[0025] The fixing plate is vertically connected to the outer wall of the guide plate, and the fixing plate is provided with a second waist hole; the fixing plate is connected to the anti-tipping frame by bolt fastening through the second waist hole, and the horizontal distance between the guide plates on both sides of the anti-tipping frame can be adjusted by adjusting the position of the bolt in the second waist hole.

[0026] Furthermore, the bottom and top of the anti-tipping frame are respectively provided with a tightening mechanism and a pressing mechanism; the tightening mechanism and the pressing mechanism are respectively used to apply downward pressure and upward thrust to the top and bottom of the photovoltaic module.

[0027] Furthermore, the bottom of the anti-tipping frame is provided with a connecting plate for connecting the smooth transport mechanism.

[0028] The operation method of the aforementioned photovoltaic module security device includes the following steps:

[0029] S1. When the photovoltaic module is transported to the anti-tipping frame through the flow transport mechanism, the lower and upper parts of the first photovoltaic module on the flow transport mechanism are blocked by the baffle and the upper baffle on the flow transport mechanism, respectively.

[0030] S2. The separation mechanism set at the bottom of the anti-tipping frame moves the first photovoltaic module on the flow transport mechanism out of the flow transport mechanism, so that the baffle on the flow transport mechanism no longer obstructs the first photovoltaic module. At this time, the first photovoltaic module is supported by the separation mechanism.

[0031] S3. The downward telescopic component set on the top of the anti-tipping frame applies downward pressure to the top of the first photovoltaic module; pressing the first photovoltaic module blocked by the rear side of the upper baffle out into the gap between the front side of the upper baffle and the blocking part;

[0032] S4. The rotating part of the rotating limiting component makes the blocking part horizontal. At this time, there is no obstruction at the top and bottom of the first photovoltaic module. The rotating feeding mechanism grabs the first photovoltaic module and moves the first photovoltaic module out of the security device.

[0033] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0034] 1. The upper baffle on the top of the anti-tipping frame and the baffle on the flow transport mechanism of the present invention respectively block the upper and lower parts of the first photovoltaic module, preventing the first photovoltaic module from tipping over at the end of the flow transport mechanism. At the same time, under the blocking effect of the first photovoltaic module, subsequent photovoltaic modules are also blocked at the end of the flow transport mechanism, realizing the positioning and blocking of the photovoltaic module at the end of the flow transport mechanism. The set rotation limiting component can block the first photovoltaic module after it is separated, so that the first photovoltaic module can be clamped by the rotation feeding mechanism and laid down horizontally. That is, the safety device of the present invention can block the photovoltaic modules, so that the photovoltaic modules can be clamped by the rotation feeding mechanism one by one and laid down horizontally.

[0035] 2. In order to prevent the photovoltaic modules from shifting to both sides during the downward sliding process at the end of the flow transport mechanism, the present invention installs guide plates on both sides of the anti-tipping frame. The front end of the guide plate is parallel to the side of the photovoltaic module, and the rear end is offset outward at a certain angle to ensure that the photovoltaic modules that have shifted too much at the rear end can be gradually guided to a suitable position. The connection between the guide plate and the anti-tipping frame adopts a waist-shaped hole, which can be used for fine adjustment of the guide position to meet the panel installation position after the photovoltaic module is rotated.

[0036] 3. The anti-tipping frame of this invention is equipped with a pressing mechanism and a top-pressing mechanism at its bottom and bottom, respectively. The function of the pressing mechanism and the top-pressing mechanism is to press down a component in the middle position to prevent more components from following behind. On the one hand, because the flow transport mechanism and the safety device are at a certain angle relative to the horizontal plane during installation (the end of the flow transport mechanism is tilted downwards at a certain angle towards the safety device), the component of the photovoltaic module's weight will act on the upper baffle. Considering the force limit of the upper baffle, the pressing mechanism and the top-pressing mechanism (two sets of pressing cylinders) are used to bear part of the component of the photovoltaic module's weight, preventing damage to the upper baffle. On the other hand, when there are many photovoltaic modules on the flow transport mechanism, the subsequent photovoltaic modules and the upper baffle will exert a certain pressure on the first photovoltaic module. If the pressure on the first photovoltaic module is too great and it gets stuck between the second photovoltaic module and the upper baffle, the separation mechanism will jam when separating the first plate.

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0044] Example 1:

[0045] like Figures 1-3 As shown, a photovoltaic module security device includes an anti-tipping frame 1, an upper baffle 9, and a rotation limiting component 3.

[0046] Anti-tipping frame 1, used for mounting other components of the security device and for allowing photovoltaic modules to pass through, has a central through-hole for the photovoltaic modules to pass through, and its bottom is used to connect to a smooth transport mechanism, such as... Figure 1 As shown, the anti-tipping frame 1 can specifically be a rectangular frame whose shape is adapted to the shape of the photovoltaic module, and the size of the rectangular through hole inside the rectangular frame is larger than that of the photovoltaic module.

[0047] In a preferred embodiment, to facilitate the connection of the smooth transport mechanism, two connecting plates 6 are provided at the bottom of the rectangular frame. The connecting plates 6 can be as follows: Figure 1 The L-shaped plate shown has its vertical section connected to the sidewall of the bottom long side of the rectangular frame, and its horizontal section flush with the upper surface of the bottom long side of the rectangular frame. The lower surface of the overlapping flow transport mechanism overlaps with the upper surface of the connecting plate 6. The flow transport mechanism is used to transport photovoltaic modules, enabling vertical transport of the modules. This flow transport mechanism is not a structure protected by this invention, and its structure will not be specifically described here.

[0048] An upper baffle 9 is positioned on the front side of the top of the anti-tipping frame 1. The upper baffle 9 is used to block the upper part of the photovoltaic module passing through the anti-tipping frame 1. To ensure that the first photovoltaic module blocked by the upper baffle 9 and the baffle at the end of the flow transport mechanism is in a vertical position, the distance between the upper baffle 9 and the baffle at the end of the flow transport mechanism in the photovoltaic module transport direction is zero. The upper baffle 9 can be positioned directly above the baffle at the end of the flow transport mechanism, or it can be positioned as follows: Figure 1 As shown, upper baffles 9 are provided on both sides of the top of the anti-tipping frame 1. The two upper baffles 9 are located on both sides of the baffle at the end of the smooth transport mechanism.

[0049] In a specific case, in order to realize that the upper baffle 9 is set on the front side of the top of the anti-tipping frame 1, when the anti-tipping frame 1 is a rectangular frame, mounting blocks 10 are provided on both sides of the top of the anti-tipping frame 1; the upper baffle 9 and the rotation limiting component 3 are both mounted on the mounting blocks 10; the mounting blocks 10 are set perpendicular to the top side wall of the anti-tipping frame 1, and the upper baffle 9 and the rotation limiting component 3 can be installed at the end of the mounting block 10 away from the top of the anti-tipping frame 1.

[0050] In a preferred embodiment, the upper baffle 9 is provided with a first waist hole, and the upper baffle 9 is connected to the end of the mounting block 10 by bolt fastening through the first waist hole. The vertical displacement of the upper baffle 9 can be achieved by adjusting the position of the bolt in the first waist hole, that is, the vertical position of the upper baffle 9 is adjustable.

[0051] In specific implementation, a downward pressing telescopic component 2 is provided on the rear side of the upper baffle 9; the downward pressing telescopic component 2 is used to press out the first photovoltaic module blocked by the rear side of the upper baffle 9 into the gap between the front side of the upper baffle 9 and the blocking part; the downward pressing telescopic component 2 can be installed on the inner side wall of the upper baffle 9, the inner side wall of the upper baffle 9 specifically refers to the side opposite to the mounting block 10, and the downward pressing telescopic component 2 can be a cylinder.

[0052] The rotation limiting assembly 3 includes a rotating part and a blocking part. One end of the rotating part is connected to the anti-tipping frame 1, specifically, it can be rotatably connected to the end of the mounting block 10. The other end is connected to the blocking part, which is located on the front side of the upper baffle 9. The two parts can be staggered, meaning the blocking part does not have to be directly in front of the upper baffle 9. Figure 2 As shown, there is a gap between the blocking part and the upper baffle 9 in the photovoltaic module transportation direction, which can be used to accommodate at least one photovoltaic module; when the blocking part rotates to the vertical position, it blocks the upper part of the photovoltaic module; when the blocking part rotates to the horizontal position, it allows the photovoltaic module to pass through; the specific shape of the blocking part can be a long strip, and the rotating part can be driven by a motor or a rotary cylinder.

[0053] In this embodiment, the upper baffle 9 on the top of the anti-tipping frame 1 and the baffle on the flow transport mechanism respectively block the upper and lower parts of the first photovoltaic module, preventing the first photovoltaic module from tipping over at the end of the flow transport mechanism. At the same time, under the blocking effect of the first photovoltaic module, subsequent photovoltaic modules are also blocked at the end of the flow transport mechanism, realizing the positioning and blocking of the photovoltaic module at the end of the flow transport mechanism. The rotating limiting component 3 can block the first photovoltaic module after it is separated, so that the first photovoltaic module can be clamped by the rotating feeding mechanism and laid down to a horizontal position.

[0054] In a preferred embodiment, guide plates 4 are provided on both sides of the anti-tipping frame 1, and the guide plates 4 are used to guide the photovoltaic modules conveyed on the smooth transport mechanism through the anti-tipping frame 1.

[0055] In one specific implementation scheme, the guide plate 4 includes an inlet section and a fixed section;

[0056] The fixed section is set on the inner wall of the anti-tipping frame 1, and the length direction of the fixed section is consistent with the transportation direction of the photovoltaic module. One end of the entrance section is connected to the fixed section, and the entrance section has an angle with the transportation direction of the photovoltaic module, so that the horizontal distance between the guide plates 4 on both sides of the anti-tipping frame 1 gradually decreases from one end of the entrance to the other end at the fixed section, that is, the entrance of the guide plate 4 has a horn structure.

[0057] The guide plate 4 described in this embodiment can prevent the photovoltaic module from shifting to both sides during the sliding process at the end of the flow transport mechanism. The guide plate 4 is installed on both sides of the anti-tipping frame 1. The front end of the guide plate 4 is parallel to the side of the photovoltaic module, and the rear end is offset outward at a certain angle to ensure that the photovoltaic module that has shifted too much at the rear end can be gradually guided to the appropriate position.

[0058] In a preferred embodiment, the guide plate 4 is disposed on the inner side of the anti-tipping frame 1 via the fixing plate 11;

[0059] The fixing plate 11 is vertically connected to the outer wall of the guide plate 4, and the fixing plate 11 is provided with a second waist hole; the fixing plate 11 is connected to the anti-tipping frame 1 by bolt fastening through the second waist hole 13, and the horizontal distance between the guide plates 4 on both sides of the anti-tipping frame 1 can be adjusted by adjusting the position of the bolt in the second waist hole 13.

[0060] The connection between the guide plate 4 and the anti-tipping frame 1 uses a waist-shaped hole, which allows for fine adjustment of the guide position to meet the panel installation position after the photovoltaic module is rotated.

[0061] In a preferred embodiment, the bottom and top of the anti-tipping frame 1 are respectively provided with a tightening mechanism 5 and a pressing mechanism 8; the tightening mechanism 5 and the pressing mechanism 8 are used to apply downward pressure and upward thrust to the top and bottom of the photovoltaic module, respectively. Specifically, the tightening mechanism 5 and the pressing mechanism 8 can be cylinders.

[0062] The function of the clamping mechanism 5 and the pressing mechanism 8 is to press down a component in the middle position to prevent more components from following. Firstly, because the flow transport mechanism and security device are installed at a certain angle relative to the horizontal plane, the component of the photovoltaic module's weight will act on the upper baffle 9. Considering the force limit of the upper baffle 9, two sets of pressing cylinders are used to bear part of the component of the photovoltaic module's weight, preventing damage to the upper baffle 9. Secondly, when there are many photovoltaic modules on the flow transport mechanism, the subsequent photovoltaic modules and the upper baffle 9 will exert some pressure on the first photovoltaic module. If the pressure on the first photovoltaic module is too great and it gets stuck between the second photovoltaic module and the upper baffle 9, the separation mechanism 7 will jam when separating the first photovoltaic module.

[0063] In practical use, a separation mechanism 7 is provided at the bottom of the anti-tipping frame 1. The separation mechanism 7 ensures that the first photovoltaic module is safely separated from the second photovoltaic module, provided that there are rigid blocks above and below the module, and then transports the first photovoltaic module to the clamping plate position. The operation process is: lifting, pushing forward, and lowering. After lifting the first photovoltaic module past the baffle of the flow transport mechanism, it is lowered to the clamping plate position, where the module can then be clamped and rotated for unloading. The separation mechanism 7 sequentially lifts, pushes forward, and lowers the first photovoltaic module, achieving the separation of the first and second photovoltaic modules. Lifting ensures that the bottom of the first photovoltaic module is higher than the baffle on the flow transport mechanism, and then pushing forward ensures that the bottom of the first photovoltaic module crosses the baffle on the flow transport mechanism. The separation mechanism 7 is not the structure to be protected by this invention, and its specific structure will not be described here.

[0064] The operation method of the photovoltaic module security device described in this embodiment includes the following steps:

[0065] S1. When the photovoltaic module is transported to the anti-tipping frame 1 by the flow transport mechanism, the lower and upper parts of the first photovoltaic module on the flow transport mechanism are blocked by the baffle and the upper baffle 9 on the flow transport mechanism, respectively.

[0066] S2. The separation mechanism 7 set at the bottom of the anti-tipping frame 1 moves the first photovoltaic module on the flow transport mechanism out of the flow transport mechanism, so that the baffle on the flow transport mechanism loses its obstruction to the first photovoltaic module. At this time, the first photovoltaic module is supported by the separation mechanism 7.

[0067] S3. The downward telescopic component 2 set on the top of the anti-tipping frame 1 applies downward pressure to the top of the first photovoltaic module; the first photovoltaic module blocked by the rear side of the upper baffle 9 is pushed out into the gap between the front side of the upper baffle 9 and the blocking part.

[0068] S4. The rotating part of the rotating limiting component 3 makes the blocking part horizontal. At this time, there is no obstruction at the top and bottom of the first photovoltaic module. The rotating feeding mechanism grabs the first photovoltaic module and moves the first photovoltaic module out of the security device.
