Description

Technical Field

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

[0002] Solar panels, also known as photovoltaic panels, are semiconductor devices that use the photovoltaic effect to convert sunlight energy directly 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 the power supply systems of 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 the power needs of remote areas. In the design of the vacuum adsorption 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 be efficient and safe.

[0003] According to patent document: CN116353973A, a convenient transport device and transport 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 transport device body. The frame body includes a first workbench and a second workbench, and the distance between the two is adjustable. The placement mechanism includes multiple limit components and receiving components. The monitoring and risk avoidance mechanism also includes a micro air pump whose air outlet is connected to the emergency airbag, and a pressure sensor set in the second mounting frame. 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 - linkage buffering structure (canceling out transportation vibrations) form a multi - level protection system. The three are synchronously triggered through mechanical transmission, which not only realizes the force balance of the entire battery panel area, 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 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 board 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 constitute a double environmental barrier. This "intelligent adsorption - flexible clamping - airtight protection" closed - loop system enables the device to still maintain the state of suppressing micron - level displacement and constant - pressure protection of the battery panel under complex working conditions such as transportation bumps and temperature and humidity changes.

The solar panel placement rack 3 is specially 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 1 to avoid shaking or collision during the transfer process.

[0037] like Figure 3 - Figure 5 As shown, the transfer box 1 includes a box shell 11, the inner wall of the box shell 11 is fixedly connected to the box inner connecting frame 12, the box shell 11 includes a box shell body 111, the bottom of the middle part of the rear side of the box shell body 111 is fixedly connected to a hydraulic push rod 113, and a slide groove 112 is opened in the middle part of the rear side of the box shell body 111.

The left and right sides of the inner connecting frame main body 121 in the box are provided with a connecting frame guide groove 125 on one side of the top of the left and right groups of guide side plates 123.

[0038] Through the above-mentioned structural setting, when the transfer box 1 is transporting the solar panel, the hydraulic push rod 113 can push the L-shaped lifting plate 115 to slide in the slide groove 112, and drive the two-way hinge block 116 and the rotating rod 117 to change the angle, so that the opening or closing of the closing panel 2 is achieved through the cooperation of the rotating rod 117 with the guide side plate 123 and the side plate guide groove 124 on the connecting frame 12 in the box. The setting of the L-shaped guide plate 114 is to perform a guiding and limiting function. In addition, the connecting frame 12 in the box is fixedly connected to the box shell body 111 through the inner connecting frame connecting block 122, which improves the connection strength between the connecting frame 12 in the box and the box shell body 111, making the overall structure of the transfer box 1 more stable, and the solar panel placement rack 3 is placed through the connecting frame 12 in the box.

[0039] like Figure 6 - Figure 9As shown, the solar panel placement rack 3 includes multiple placement plates 31, and the outer sides of the multiple placement plates 31 are provided with placement plate push-pull control components 32. The bottom of the middle part of the rear side of the placement plate push-pull control component 32 is fixedly connected with two springs 33. The multiple placement plates 31 include a placement plate bottom plate 311, and the middle part of the front side of the bottom of the multiple placement plate bottom plates 311 is fixedly connected with a second hydraulic push rod 312. The middle part of the bottom of the multiple placement plate bottom plates 311 is rotatably connected with a rotating rod 314. The four sides of the bottom of the multiple placement plate bottom plates 311 are fixedly connected with a placement plate guide rod 313. The left and right sides of the multiple placement plate bottom plates 311 are slidably connected to the inner wall of the side plate guide groove 124 opened by the multiple groups of guide side plates 123. The top of the multiple placement plate bottom plates 311 is fixedly connected with an adsorption control plate 315. The top of 315 is fixedly connected with a concave plate 316, and the middle part of the top of multiple concave plates 316 is honeycomb-shaped. Concave plate guide grooves 317 are opened on the front and back sides of multiple concave plates 316. The outer walls of multiple groups of placement plate guide rods 313 are slidably connected with concave blocks 318, and the bottoms of multiple groups of concave blocks 318 are fixedly connected with expansion rods 319. The front and back sides of the tops of multiple expansion rods 319 on the left and multiple expansion rods 319 on the right are fixedly connected with columnar uprights 3111. The tops of multiple groups of columnar uprights 3111 are fixedly connected with rubber right-angle clamps 3112. The outer sides of multiple groups of rubber right-angle clamps 3112 are fixedly connected with clamp slides 3113. The outer walls of multiple groups of clamp slides 3113 are slidably connected to the inner walls of the two concave plate guide grooves 317 opened by multiple concave plates 316.At the middle of the bottom of multiple left and right expansion and contraction rods 319, there are second rotating rods 3110 rotatably connected. On the front and rear sides of the bottom of multiple rotating rods 314, the sides away from the expansion and contraction rods 319 at the top of multiple groups of second rotating rods 3110 are rotatably connected. On the left side of multiple right expansion and contraction rods 319, the right ends of multiple second hydraulic push rods 312 are fixedly connected. The placement plate push-pull control component 32 includes a lifting vertical rod 321. At the rear side of the lifting vertical rod 321, there is a pressing block 322 fixedly connected. At both sides of the bottom of the pressing block 322, the top ends of two springs 33 are fixedly connected. The bottom ends 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. At the front side of the lifting vertical rod 321, there are multiple bidirectional hinged cross bars 323 fixedly connected. On the left and right sides of multiple bidirectional hinged cross bars 323, there are rotating side plates 324 rotatably connected. 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. On the side away from the bidirectional hinged cross bar 323 on the inner side of multiple groups of rotating side plates 324, there are rotating side plate connecting blocks 325 rotatably connected. On the inner side of multiple groups of rotating side plate connecting blocks 325, there are L-shaped connecting blocks 326 fixedly connected. On the inner side of multiple groups of L-shaped connecting blocks 326, they extend to the inner wall of the box body connecting frame main body 121 through multiple connecting frame guiding grooves 125 opened on the left and right sides of the box body connecting frame main body 121 and the bottoms are fixedly connected to the middle parts of the left and right sides of the tops of multiple placement 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 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 placement plate bottom plate 311 to slide in the guiding side plate 123 and the side plate guiding groove 124 through the L-shaped connecting block 326, realizing the extension of the placement 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 can make the lifting vertical rod 321 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 placement 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, avoiding shaking or collision during the movement process.

[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, horizontal sliding rods 22 are fixedly connected. The outer walls of the two groups of horizontal 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 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 closing plate 2 in the closed state can effectively prevent external dust or moisture from entering the transfer box 1 and damaging the solar panels. At the same time, the sealing design between the closing plate 2 and the transfer box 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] The working principle of the present invention is as follows: when the solar panel needs to be transported, the operator can first move the transport box 1 to the specified position and position the transport box 1 by bolts, and then control the extension and contraction of the hydraulic push rod 113 to pull the L-shaped lifting plate 115 to slide in the slide groove 112, and drive the two-way hinge block 116 and the rotating rod 117 to change the angle. The two rotating rods 117 rotate to push the two expansion plates 25 to expand outward, and at the same time drive the columnar connecting rod 24, the side connecting rod 23 and the closing plate body 21 to slide along the guide groove 118 to realize the smooth opening of the closing plate 2. When the two closing plate bodies 21 move outward to a certain position, at this time, the hydraulic push rod 113 pulls the L-shaped lifting plate 115, which moves downward on the inner wall of the slide groove 112 opened in the box shell body 111, to fall to a certain position. When the cam 321 is in the upright position, the locking cam 322 is in the upright position, and the locking cam 323 is in the upright position, so that the locking cam 323 is locked.

[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 plate 315 in the solar panel placement plate 31 with the solar panel is started. The suction force generated by the adsorption control plate 315 can firmly adsorb the solar panel on the top of the concave plate 316. The honeycomb design on the top of the concave plate 316 can make the solar panel more evenly stressed during adsorption. At the same time, it increases the adsorption area and improves the adsorption effect. Subsequently, the operator can control the extension and retraction of the second hydraulic push rod 312 to push the rotating rod 314 and the expansion rod 319 to change the angle. The expansion rod 319 drives the rubber right-angle clamp 3112 to move inward under the guidance of the concave plate guide groove 317 and the clamp slide rod 3113 through the columnar vertical rod 3111, thereby clamping and fixing the solar panel to ensure its stability during transportation. After the solar panel is placed and fixed, the operator can control the extension and contraction of the hydraulic push rod 113 to make the L-shaped lifting plate 115 slide upward in the slide groove 112, and drive the two-way hinge block 116 and the rotating rod 117 to rotate in the opposite direction, thereby pushing the closing plate body 21 to move inward along the guide groove 118 through the expansion plate hinge block 26 and the columnar connecting rod 24 and other structures to achieve smooth closing of the closing plate 2. In the process of closing the closing plate 2, the pressure block 322 gradually rises and resets under the elastic force of the spring 33, driving the lifting vertical rod 321 and the two-way hinged cross bar 323 to rise, causing the rotating side plate 324 to rotate in the opposite direction, and then pulling the placement plate bottom plate 311 to slide inward along the guide side plate 123 and the side plate guide groove 124 by rotating the side plate connecting block 325 and the L-shaped connecting block 326, and retracting the multiple placement plates 31 into the transfer box 1.

[0045] At this time, the L-shaped lifting plate 115 continues to rise until it returns to its original position, completing the closure of the transfer box. During the entire transfer process, the precisely controlled mechanical structure and adsorption fixing method effectively avoid scratches and damage to the solar panels during the transfer process, thereby improving the transfer efficiency and safety. In addition, multiple solar panels are placed in layers through multiple placement plates 31. When the inner wall of the transfer box 1 is bumpy during transportation, each solar panel is placed and fixed separately, further reducing the collision and friction between the solar panels, thereby improving the protection effect during the transfer process. The rubber right-angle clamp 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 wear on the surface of the solar panel, thereby further improving the safety and protection effect of the transfer process.
