Description

Technical Field

[0001] The invention relates to the technical field of solar cell panels, and in particular to a vacuum adsorption type scratch-free transport device for solar cell panels. Background Art

[0002] Solar panels, also known as photovoltaic panels, are semiconductor devices that use the photovoltaic effect to directly convert sunlight into electrical energy. This device is mainly composed of semiconductor materials such as silicon. It can directly convert the received sunlight into electrical energy without going through the intermediate process of thermal energy conversion, which makes it highly efficient in energy conversion. Solar panels are an indispensable core component in solar power generation systems. They are widely used in power supply systems for residential, commercial buildings and industrial facilities. In addition, solar panels also play a vital role in the energy supply of spacecraft, remote communication base stations and electricity needs in remote areas. In the design of the vacuum adsorption type scratch-free transfer device for solar panels, solar panels are key components that need to be transferred, and their safe transfer is particularly important. In order to ensure that the solar panels are not damaged during the transfer process, thereby maintaining their optimal power generation efficiency and extending their service life, the transfer device must have high efficiency and safety characteristics.

[0003] According to the patent document: CN116353973A, a convenient transportation device and transportation method for solar panels are disclosed. Its technical solution includes: a frame body and a placement mechanism and a monitoring and risk avoidance mechanism installed on the frame body, thereby forming a main body of the transportation device, the frame body includes a first workbench and a second workbench, the distance between the two is adjustable, the placement mechanism includes a plurality of limit components and receiving components, the monitoring and risk avoidance mechanism also includes a micro air pump connected to the air outlet end and the emergency airbag, and a pressure sensor arranged in the second mounting frame, and the pressure sensor is provided with a pressure threshold. The present invention can monitor the transportation status of the solar panel in real time through the setting of the monitoring and risk avoidance mechanism, and can prevent the solar panel from being damaged by strong external force through the timely protection of the emergency airbag.

[0004] During the transportation of solar panels, a specially designed box is usually used to load these sensitive devices. Multiple solar panels are placed on the inner wall of these boxes. To prevent them from colliding with each other during transportation, sponges are used as separation materials. This sponge separation method aims to provide a certain degree of protection to reduce the possibility of direct contact between solar panels. However, although this method can provide protection to a certain extent, it is not perfect. There are some obvious deficiencies in the traditional transportation method. The most prominent problem is the limitation of the sponge separation effect. Due to the limited buffering capacity of the sponge, it cannot completely eliminate the friction and impact generated by the bumps and shakes of solar panels during transportation. This continuous shaking and friction may cause scratches or other forms of damage on the surface of solar panels. Although these damages may seem insignificant, they may have a greater negative impact on the performance and lifespan of solar panels. Therefore, finding a more effective protection measure to ensure the safety of solar panels during transportation is an important challenge faced by the current logistics industry.

[0019] Compared with the prior art, the present invention has at least the following beneficial effects:

[0020] (1) The synergistic effect of triple protection of adsorption - clamping - buffering. The vacuum adsorption technology of the honeycomb - shaped concave plate (uniformly dispersing stress), the elastic clamping of the rubber right - angled clamping block (avoiding rigid contact), and the spring - linked buffering structure (canceling out transportation vibrations) form a multi - level protection system. The three are synchronously triggered through mechanical transmission, which not only achieves the global force balance of the battery panel, but also completely eliminates the risk of scratches through the complementary material characteristics (rigid frame + elastic contact). The protection efficiency is greatly improved compared with the traditional single - stage isolation method.

[0021] (2) The electromechanical coordination of dynamic closing and space optimization. When the hydraulic push rod drives the closing plate to open and close, the two - way hinge block - rotating rod mechanism synchronously drives the placement plate push - pull control component, so that actions such as the opening and closing of the box body, the telescoping of the layered placement plate, and the reset of the clamping mechanism are completed integrally. This "single - input - multi - output" linkage design not only ensures the operation efficiency (shortening the loading and unloading time), but also realizes the zero - interference three - dimensional arrangement of multiple battery panels in the limited box body space through the precise cooperation of the guide groove and the slide rail.

[0022] (3) The system coordination of adaptive load and environmental stability. The adsorption control plate automatically adjusts the negative pressure intensity according to the size of the battery panel, forming a dynamic match with the adjustable second hydraulic push rod (controlling the clamping force); at the same time, the L - shaped guide plate and the sealed closing plate form a double environmental barrier. This "intelligent adsorption - flexible clamping - airtight protection" closed - loop system enables the device to still maintain the state of suppressing the micron - level displacement of the battery panel and constant - pressure protection under complex working conditions such as transportation bumps, temperature and humidity changes.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] As Figure 1 - Figure 2 shown, the present invention provides a vacuum adsorption type solar panel scratch-free transfer device, including a transfer box 1, a closing plate 2 is arranged on the front side of the transfer box 1, and a solar panel placement rack 3 is arranged on the inner wall of the transfer box 1.

[0036] Through the provided transfer box body 1 and the closing plate 2, the solar panels can be effectively protected and fixed, preventing the solar panels from being scratched due to external impacts or vibrations during the transfer process. The design of the transfer box body 1 takes into account the size and shape of the solar panels to ensure that the solar panels can be stably placed inside. At the same time, the setting of the closing plate 2 can effectively close the front opening of the transfer box body 1, improving the overall protection performance. The solar panel placement rack 3 is specifically designed according to the characteristics of the solar panels to ensure that the solar panels can be safely and stably placed in the transfer box body 1, avoiding shaking or collision during the transfer process.

[0037] As Figure 3 - Figure 5 shown, the transfer box body 1 includes a box body outer shell 11. The inner wall of the box body outer shell 11 is fixedly connected with an inner box body connecting frame 12. The box body outer shell 11 includes a box body outer shell main body 111. The bottom of the middle part of the rear side of the box body outer shell main body 111 is fixedly connected with a hydraulic push rod 113. A chute 112 is opened in the middle part of the rear side of the box body outer shell main body 111. The top and bottom of the rear sides of the left and right sides of the box body outer shell main body 111 are fixedly connected with L-shaped guide plates 114. The top of the hydraulic push rod 113 is fixedly connected with an L-shaped lifting plate 115. The outer wall of the bottom of the front side of the L-shaped lifting plate 115 is slidably connected to the inner wall of the chute 112 opened in the middle part of the rear side of the box body outer shell main body 111. The top of the front side of the L-shaped lifting plate 115 is fixedly connected with a two-way hinge block 116. Rotating rods 117 are rotatably connected to both the left and right sides of the two-way hinge block 116. Guide grooves 118 are opened at the top and bottom of the left and right sides of the front side of the box body outer shell main body 111. The inner box body connecting frame 12 includes an inner box body connecting frame main body 121.

Connecting frame guide grooves 125 are opened on one side of the top of the left and right groups of guide side plates 123 on both the left and right sides of the inner box body connecting frame main body 121.

[0038] Through the above structural settings, when the transfer box body 1 transfers the solar panels, the hydraulic push rod 113 can be used to push the L-shaped lifting plate 115 to slide in the chute 112, and drive the double-jointed block 116 and the rotating rod 117 to change the angle. Thus, through the cooperation of the rotating rod 117 with the guiding side plate 123 and the side plate guiding groove 124 on the connecting frame 12 inside the box body, the opening or closing of the closing plate 2 can be realized. The setting of the L-shaped guiding plate 114 serves as a guiding and limiting function. In addition, the connecting frame 12 inside the box body is fixedly connected to the box body shell main body 111 through the inner connecting frame connecting block 122, which improves the connection strength between the connecting frame 12 inside the box body and the box body shell main body 111, making the overall structure of the transfer box body 1 more stable. The solar panel placement rack 3 is placed through the connecting frame 12 inside the box body.

[0039] Such as Figure 6 - Figure 9As shown, the solar panel placement rack 3 includes a plurality of placement plates 31. A placement plate push-pull control component 32 is arranged on the outer side of the plurality of placement plates 31. Two springs 33 are fixedly connected to the bottom of the middle part at the rear side of the placement plate push-pull control component 32. The plurality of placement plates 31 all include placement plate bottom plates 311. The middle parts of the front sides of the bottoms of the plurality of placement plate bottom plates 311 are fixedly connected with second hydraulic push rods 312. The middle parts of the bottoms of the plurality of placement plate bottom plates 311 are rotatably connected with rotating rods 314. The four sides of the bottoms of the plurality of placement plate bottom plates 311 are fixedly connected with placement plate guide rods 313. The left and right sides of the plurality of placement plate bottom plates 311 are slidably connected to the inner walls of the side plate guide grooves 124 opened in multiple groups of guide side plates 123. The tops of the plurality of placement plate bottom plates 311 are fixedly connected with adsorption control plates 315. The tops of the plurality of adsorption control plates 315 are fixedly connected with concave plates 316. The middle parts of the tops of the plurality of concave plates 316 are designed in a honeycomb shape. The front and rear sides of the plurality of concave plates 316 are provided with concave plate guide grooves 317. The outer walls of the plurality of groups of placement plate guide rods 313 are slidably connected with concave blocks 318. The bottoms of the plurality of groups of concave blocks 318 are fixedly connected with expansion and contraction rods 319. The front and rear sides of the tops of the left plurality of expansion and contraction rods 319 and the right plurality of expansion and contraction rods 319 are fixedly connected with columnar vertical rods 3111. The tops of the plurality of groups of columnar vertical rods 3111 are fixedly connected with rubber right-angle clamping blocks 3112. The outer sides of the plurality of groups of rubber right-angle clamping blocks 3112 are fixedly connected with clamping block sliding rods 3113. The outer walls of the plurality of groups of clamping block sliding rods 3113 are slidably connected to the inner walls of the two concave plate guide grooves 317 opened in the plurality of concave plates 316.A second rotating rod 3110 is rotatably connected to the middle of the bottom of multiple expansion and contraction rods 319 on the left side and multiple expansion and contraction rods 319 on the right side. The front and rear sides of the bottom of multiple rotating rods 314 are rotatably connected to the sides of the tops of multiple groups of second rotating rods 3110 far from the expansion and contraction rods 319. The left sides of multiple expansion and contraction rods 319 on the right side are fixedly connected to the right ends of multiple second hydraulic push rods 312. The placing plate push-pull control assembly 32 includes a lifting vertical rod 321. A pressing block 322 is fixedly connected to the rear side of the lifting vertical rod 321. The two sides of the bottom of the pressing block 322 are fixedly connected to the tops of two springs 33. The bottoms of the two springs 33 are fixedly connected to the bottom of the inner wall of the chute 112 opened in the box body housing main body 111. Multiple bidirectional hinged cross bars 323 are fixedly connected to the front side of the lifting vertical rod 321. Rotating side plates 324 are rotatably connected to the left and right sides of multiple bidirectional hinged cross bars 323. The outer wall of the pressing block 322 is slidably connected to the inner wall of the chute 112 opened in the box body housing main body 111 on one side of the bottom of the L-shaped lifting plate 115. The inner sides of multiple groups of rotating side plates 324 far from the bidirectional hinged cross bars 323 are rotatably connected to rotating side plate connection blocks 325. L-shaped connection blocks 326 are fixedly connected to the inner sides of multiple groups of rotating side plate connection blocks 325. The inner sides of multiple groups of L-shaped connection blocks 326 extend to the inner wall of the box body connection frame main body 121 through multiple connection frame guiding grooves 125 opened on the left and right sides of the box body connection frame main body 121 and the bottoms are fixedly connected to the middle of the left and right sides of the tops of multiple placing plate bottom plates 311.

[0040] Through the above structural settings, the solar panel placement rack 3 can adjust its position more flexibly in the transfer box body 1. When it is necessary to place or take out the solar panel, the lifting vertical rod 321 can drive the bidirectional hinged cross bar 323 and the rotating side plate 324 to change the angle, so as to push the placing plate bottom plate 311 to slide in the guiding side plate 123 and the side plate guiding groove 124 through the L-shaped connection block 326, realizing the extension of the placing plate 31 when the closing plate 2 is opened or the retraction when the closing plate 2 is closed. The setting of the spring 33 enables the lifting vertical rod 321 to automatically reset when not affected by external forces. At the same time, the second hydraulic push rod 312 can push the rotating rod 314 and the expansion and contraction rod 319 to change the angle, so as to clamp or release the solar panel through the columnar vertical rod 3111 and the rubber right-angle clamp block 3112, realizing the rapid fixation and loosening of the solar panel. The honeycomb design of the concave plate 316 can increase the contact area between it and the solar panel and improve the adsorption effect. The settings of the concave plate guiding groove 317 and the clamp sliding rod 3113 can ensure the stability of the rubber right-angle clamp block 3112 during the clamping process. In addition, the settings of the placing plate guiding rod 313 and the concave block 318 can guide and limit the movement of the expansion and contraction rod 319 and the columnar vertical rod 3111, preventing them from shaking or colliding during the movement.

[0041] Such as Figure 10As shown in the figure, the closing plate 2 includes two closing plate bodies 21. The rear sides of the two closing plate bodies 21 are slidably connected to the left and right sides of the outer wall of the box body shell main body 111. At the top and bottom of the rear sides of the two closing plate bodies 21, transverse sliding rods 22 are fixedly connected. The outer walls of the two groups of transverse sliding rods 22 are slidably connected to the inner walls of two groups of guiding grooves 118 opened on the front side of the box body shell main body 111. At the top and bottom of the outer sides of the two closing plate bodies 21, side connecting rods 23 are fixedly connected. At the rear sides of the outer sides of the two groups of side connecting rods 23, columnar connecting rods 24 are fixedly connected. At the outer ends of the two groups of columnar connecting rods 24, expansion and contraction plates 25 are fixedly connected. At the rear sides of the inner sides of the two groups of expansion and contraction plates 25, expansion and contraction plate hinge blocks 26 are fixedly connected. The outer walls of the two groups of columnar connecting rods 24 are rotatably connected to the front inner walls of the two groups of L-shaped guiding plates 114. The inner walls of the two expansion and contraction plate hinge blocks 26 are rotatably connected to the outer walls of the two rotating rods 117 on the side away from the double hinge block 116.

[0042] Through the above structural settings, when the closing plate 2 opens or closes the transfer box body 1, the rotating rod 117 can drive the expansion and contraction plate hinge block 26 and the expansion and contraction plate 25 to change the angle, so as to push the closing plate body 21 to slide in the guiding groove 118 opened on the front side of the box body shell main body 111 through the columnar connecting rod 24 and the side connecting rod 23, realizing the smooth opening or closing of the closing plate 2. The setting of the L-shaped guiding plate 114 can not only conduct guiding and limiting, but also increase the stability of the closing plate 2 when it is closed. The closed state of the closing plate 2 can effectively prevent external dust or moisture from entering the transfer box body 1 and damaging the solar panels. At the same time, the sealing design between the closing plate 2 and the transfer box body 1, such as using rubber sealing strips, can further improve the overall protection performance. When it is necessary to open the closing plate 2, only by operating through a driving mechanism such as the hydraulic push rod 113, the smooth opening of the closing plate 2 can be easily realized, which is convenient for the placement or removal of the solar panels. In addition, the design of the entire transfer device takes into account the convenience and practicality of operation, enabling the operator to easily complete the transfer work of the solar panels and improving the work efficiency.

[0043] Working principle of the present invention: When it is necessary to transfer the solar panel, the operator can first move the transfer box body 1 to the designated position and position the transfer box body 1 through bolts. Then, by controlling the telescopic movement of the hydraulic push rod 113, the L-shaped lifting plate 115 is pulled to slide in the chute 112, and the two-way hinge block 116 and the rotating rod 117 are driven to change the angle. The two rotating rods 117 rotate to push the two expansion and contraction plates 25 to expand outward. At the same time, the columnar connecting rod 24, the side connecting rod 23 and the main body of the closing plate 21 are driven to slide along the guiding groove 118, realizing the smooth opening of the closing plate 2. When the two main bodies of the closing plate 2 move outward to a certain position, at this time, when the L-shaped lifting plate 115 that is pulled by the hydraulic push rod 113 and moves downward along the inner wall of the chute 112 opened in the main body of the box shell 111 drops to a certain position, at this time, the L-shaped lifting plate 115 contacts the top of the pressing block 322 fixed to the rear side of the lifting vertical rod 321 at the bottom of one side of the inner wall of the chute 112 opened in the main body of the box shell 111. As the L-shaped lifting plate 115 continues to drop, the pressing block 322 is subjected to the pressing force of the L-shaped lifting plate 115, driving the lifting vertical rod 321 to move downward. At this time, the spring 33 is compressed and generates elastic force. At the same time, the lifting vertical rod 321 drives the two-way hinge cross rod 323 to move downward to change the angle of the rotating side plate 324. The rotating side plate 324 pushes the bottom plate of the placing plate 311 to slide in the guiding side plate 123 and the side plate guiding groove 124 through the rotating side plate connecting block 325 and the L-shaped connecting block 326, so that the plurality of placing plates 31 extend out of the transfer box body 1, facilitating the operator to place the solar panel on the placing plate 31. After the plurality of placing plates 31 move out of the outer wall of the transfer box body 1.

[0044] At this time, the staff can place the solar panel on the top of the concave plate 316. At this time, the adsorption control board 315 in the solar panel placement board 31 is activated. Through the suction force generated by the adsorption control board 315, the solar panel is firmly adsorbed on the top of the concave plate 316. The honeycomb design on the top of the concave plate 316 can make the solar panel receive more uniform force during adsorption. At the same time, it increases the adsorption area and improves the adsorption effect. Subsequently, the operator can control the telescopic movement of the second hydraulic push rod 312 to drive the rotating rod 314 and the expansion and contraction rod 319 to change the angle. The expansion and contraction rod 319 drives the rubber right-angle clamp block 3112 to move inward under the guidance of the concave plate guide groove 317 and the clamp block slide rod 3113 through the columnar vertical rod 3111, so as to clamp and fix the solar panel to ensure its stability during transportation. After the placement and fixation of the solar panel are completed, the operator can control the telescopic movement of the hydraulic push rod 113 to make the L-shaped lifting plate 115 slide upward in the chute 112, and drive the double-jointed block 116 and the rotating rod 117 to rotate in the reverse direction. Thus, through structures such as the expansion and contraction plate hinge block 26 and the columnar connecting rod 24, the main body of the closing plate 21 is pushed to move inward along the guide groove 118 to realize the smooth closing of the closing plate 2. During the closing process of the closing plate 2, the pressing block 322 gradually rises and resets under the elastic force of the spring 33, driving the lifting vertical rod 321 and the double-jointed cross bar 323 to rise, making the rotating side plate 324 rotate in the reverse direction. Furthermore, through the rotating side plate connecting block 325 and the L-shaped connecting block 326, the bottom plate 311 of the placement plate is pulled to slide inward along the guide side plate 123 and the side plate guide groove 124, and multiple placement plates 31 are retracted into the transportation box body 1.

[0045] At this time, the L-shaped lifting plate 115 continues to rise until it completely returns to the initial position, completing the closing of the transportation box body. During the entire transportation process, through the precisely controlled mechanical structure and adsorption and fixation method, scratches and damages to the solar panel during transportation are effectively avoided, and the transportation efficiency and safety are improved. In addition, multiple solar panels are placed in layers through multiple placement plates 31. When the inner wall of the transportation box body 1 jolts during transportation, since each solar panel is placed and fixed separately, the collision and friction between the solar panels are further reduced, improving the protection effect during transportation. The rubber right-angle clamp block 3112 is made of rubber, with good elasticity and wear resistance. When clamping and fixing the four corners of the solar panel, it can not only ensure stability but also reduce the wear on the surface of the solar panel, further enhancing the safety and protection effect during transportation.
