Description

Technical Field

[0001] The utility model relates to the field of photovoltaic panel transportation, and particularly to a transportation device for high-position installation of photovoltaic panels. Background Art

[0002] In the deployment of large-scale photovoltaic power generation systems, especially in the construction scenarios of vast regions, in order to maximize the light energy utilization rate per unit area, fixed photovoltaic brackets are designed to ensure that the photovoltaic panels can maintain the most ideal light incidence angle. Although this strategy improves the energy collection efficiency, it also brings installation challenges: in order to conform to the terrain and capture the best sunlight angle, the layout of the brackets often results in a vertical distance of up to 3 to 5 meters between the high side and the ground, and there is also a height difference of about 1.5 meters on the low side.

[0003] Under this background, the laying operation of photovoltaic panels becomes particularly complex and difficult. The traditional laying process usually starts from the low end of the inclined plane and relies on teamwork. The photovoltaic panels need to be delivered to the top of the inclined plane for installation through multiple manual relays. This process not only takes time and effort, requires precise cooperation among multiple staff members to repeatedly transfer heavy photovoltaic panel components in a relay form, but also significantly increases the labor intensity. Moreover, the high-frequency manual transfer is not only inefficient but also hides high risks. If care is not taken, the photovoltaic panels may slip, posing a serious threat to the safety of personnel and equipment below, and the accident risk increases sharply.

[0004] Therefore, in view of the above problems, the applicant has developed a transportation device for high-position installation of photovoltaic panels to reduce the labor intensity and risk of manually handling photovoltaic panels and improve the overall construction efficiency of photovoltaic power stations. Summary of the Utility Model

[0005] The utility model aims to provide a transportation device for high-position installation of photovoltaic panels to reduce the labor intensity and risk of manually handling photovoltaic panels and improve the overall construction efficiency of photovoltaic power stations.

[0006] To achieve the above object, the utility model adopts the following technical scheme: A transportation device for high-position installation of photovoltaic panels includes a transfer box for loading photovoltaic panels and a lifting and conveying mechanism for lifting and conveying photovoltaic panels. The transfer box and the lifting and conveying mechanism are detachably connected. A side door is hinged on one side of the transfer box connected to the lifting and conveying mechanism; the lifting and conveying mechanism includes a support plate and two groups of lifting components fixed on the support plate. Each group of lifting components includes a fixed pulley fixed at the upper end of the support plate and a hoisting motor fixed at the lower end. The sling of the hoisting motor is connected with a supporting seat through the fixed pulley; the transfer box includes a bottom plate and a box body. Two symmetrical chutes are opened on the bottom plate, and sliding seats for placing photovoltaic panels are arranged in the chutes.

[0007] The principle and advantages of this scheme are:

[0008] In actual application, the transfer box equipped with photovoltaic panels in this solution is transported to a trolley by auxiliary transportation equipment such as a forklift. Workers detachably fix the lifting and conveying mechanism on one side of the transfer box with a side door, and ensure that the top of the supporting seat is not higher than the bottom wall of the chute. Then, workers on the ground push the photovoltaic panels into the supporting seat. The lifting motor starts, and through a fixed pulley and a sling, the supporting seat and the photovoltaic panels are lifted upward. During the upward transportation of the photovoltaic panels, workers located on the installation bracket or scaffolding grab the upper end of the photovoltaic panels and guide them to the laying position for installation and fixation; then the above operations are repeated for subsequent transportation of the photovoltaic panels.

[0009] 1. Compared with the existing method of completely relying on manual lifting during the installation of photovoltaic panels, in this solution, the lifting and conveying structure is used to replace the lifting work of ground workers. Ground workers only need to push the photovoltaic panels along the chute into the supporting seat, which greatly reduces the labor intensity of ground workers, and significantly reduces the risk of slipping caused by manual transfer, significantly improves the safety of on-site operations, and reduces potential harm to personnel and equipment below; and because ground workers have better preserved physical strength, they can exchange work with workers on the installation bracket, ensuring that the workers receiving the photovoltaic panels above have sufficient physical strength, ensuring the transportation safety and laying efficiency of the photovoltaic panels, and at the same time, it is also beneficial to maintain the health status and long-term work efficiency of the staff.

[0010] 2. In this solution, the transfer box and the lifting and conveying structure are detachably connected. The lifting and conveying structure can be repeatedly installed on multiple transfer boxes for transporting photovoltaic panels. Compared with setting a lifting and conveying structure on each transfer box, this solution effectively saves the transfer cost, and the transfer box and the lifting and conveying structure being two separate structures reduces the overall volume of the transfer box, occupies less space in the transport carriage, increases the single - time transport volume of photovoltaic panels by the transport vehicle, and is beneficial to reducing the transport cost and the overall construction cost of the photovoltaic power station.

[0011] Further, the upper part of the supporting seat is a wedge - shaped opening. When the supporting seat is at the lowest end, the top of the wedge - shaped opening is flush with the bottom wall of the chute.

[0012] The above setting facilitates workers to quickly push the photovoltaic panels into the supporting seat and ensures the smooth process of the photovoltaic panels entering the supporting seat, effectively avoiding bump damage to the photovoltaic panels.

[0013] Further, balls are installed at the bottom of the chute.

[0014] The above balls avoid the direct contact between the sliding seat and the chute, change the sliding friction into rolling friction, reduce the friction loss, extend the service life of the equipment. At the same time, the ball design makes it easier for workers to push the photovoltaic panels, effectively improving the installation efficiency of the photovoltaic panels.

[0015] Further, a rotating shaft is rotatably connected to the top of the support plate, and the rotating shafts are distributed along the width direction of the support plate.

[0016] The above setting is beneficial to reducing the friction between the photovoltaic panel and the support plate when the photovoltaic panel rises in an inclined state, and reducing the frictional damage to the photovoltaic panel.

[0017] Further, a buffer assembly is provided on one side of the upper part of the support plate facing the transfer box. The buffer assembly includes a spring fixed to the support plate, and a buffer layer is fixed to the free end of the spring. The buffer layer is made of a low-friction elastic material.

[0018] When the angle adjustment structure causes the support seat and the photovoltaic panel to tilt towards the support plate, the above setting reduces the collision between the photovoltaic panel and the support plate when the photovoltaic panel tilts and the friction between the photovoltaic panel and the support plate when the photovoltaic panel continues to rise after tilting, reducing the damage to the photovoltaic panel.

[0019] Further, a forklift opening penetrating horizontally is formed in the bottom plate. This facilitates the forklift to transfer the entire transfer box, reducing the labor intensity of manual handling.

[0020] Further, the box body includes an upper box body and a lower box body, which are hinged to each other. In specific use, the lower box body is rotated downward, facilitating the loading of the photovoltaic panel and facilitating the worker to hold the upper end of the photovoltaic panel and push the photovoltaic panel into the support seat.

[0030] Embodiment 1

[0031] As Figures 1 - 5 shown, a transporting device for high-position installation of photovoltaic panels includes a transfer box 1 for loading photovoltaic panels and a lifting and conveying mechanism 2 for lifting and conveying photovoltaic panels. A side door is hinged to one side of the transfer box 1 connected to the lifting and conveying mechanism 2. The connection between the transfer box 1 and the lifting and conveying mechanism 2 is detachable, and the implementation forms of the detachable connection include but are not limited to hook connection, snap connection, pin connection, etc. In this embodiment, the transfer box 1 and the lifting and conveying mechanism 2 are connected by a hanging buckle. A lifting ring (not shown in the figure) is provided on the transfer box 1, and a hook (not shown in the figure) is provided on the lifting and conveying mechanism 2. The hook hooks the lifting ring to realize the connection between the two.

[0032] As Figure 2 、 Figure 3 shown, the lifting and conveying mechanism 2 includes a support plate 26 and two groups of lifting components fixed on the support plate 26. The lifting components are installed on the side facing the transfer box 1. Each group of lifting components includes a fixed pulley 21 fixed at the upper end of the support plate 26 and a hoisting motor 22 fixed at the lower end. The sling of the hoisting motor 22 is connected with a supporting seat 23 through the fixed pulley 21. A groove for accommodating the photovoltaic panel is formed on the supporting seat 23. The hoisting motor 22 is a forward and reverse motor; As Figure 4 、 Figure 5 shown, the transfer box 1 includes a bottom plate 12 and a box body 11. Two symmetrical chutes 13 are formed on the bottom plate 12. A sliding seat 14 for placing the photovoltaic panel is arranged in the chute 13. A ball 15 is installed at the bottom of the chute 13. When the supporting seat 23 is at the bottommost position, the top of the supporting seat 23 is not higher than the bottom wall of the chute 13. Preferably, as Figure 2 shown, in this embodiment, the upper part of the supporting seat 23 is a wedge-shaped opening that gradually expands outwards. The top of the wedge-shaped opening is flush with the bottom wall of the chute 13, which is convenient for workers to quickly push the photovoltaic panel into the supporting seat 23. Further, the box body 11 includes an upper box body and a lower box body. The lower box body is fixed on the bottom plate 12. The upper box body and the lower box body are hinged. The four side walls of the upper box body are all independent side walls. In specific applications, each side wall of the upper box body is separated and rotated downwards, which is convenient for loading the photovoltaic panel and for workers to hold the upper end of the photovoltaic panel and push the photovoltaic panel into the supporting seat 23.

[0033] As Figure 5As shown, further, a forklift opening 16 penetrating transversely is formed in the bottom plate 12. The forklift opening 16 is located at the bottom of the chute 13 and there is a certain distance between the top of the forklift opening 16 and the bottom wall of the chute 13, facilitating the forklift to transfer the entire transfer box 1 and reducing the labor intensity of manual handling.

[0034] The specific implementation process is as follows:

[0035] In specific applications, the transfer box 1 filled with photovoltaic panels is transported from the factory to the construction site. After arriving at the construction site, the forklift unloads and transports the transfer box 1 through the forklift opening 16. The forklift places the transfer box 1 on the trolley, and the worker transports the photovoltaic panels to the laying position through the trolley. Then, the side opening door is opened, and the lifting and conveying mechanism 2 is connected and fixed to the transfer box 1. When the two are fixed, the top of the wedge-shaped opening of the supporting seat 23 is flush with the bottom of the chute 13.

[0036] After the entire conveying device is fixed, the worker on the ground pushes the photovoltaic panels along the chute 13 to move into the supporting seat 23, presses the button of the control switch 28, and the hoisting motor 22 starts. Through the fixed pulley 21 and the sling, the supporting seat 23 and the photovoltaic panels are driven to move upward. During the upward movement, the photovoltaic panels in the supporting seat 23 tilt towards the support plate side due to lack of vertical support and fixation. After the photovoltaic panels tilt, their upper ends are lapped on the rotating shaft at the top of the support plate 26. The photovoltaic panels continue to be conveyed upward, and the top of the photovoltaic panels gradually laps on the cross beam of the installation bracket. The worker on the installation bracket guides the photovoltaic panels to the correct laying position during the conveying process and then installs and fixes them; then the supporting seat 23 resets to the bottom, and the worker on the ground continues to push the subsequent photovoltaic panels into the supporting seat 23 for lifting and conveying, repeating the above process.

[0037] Embodiment 2

[0038] Compared with Embodiment 1, as Figure 6 、 Figure 7 Combined with the figure shown, in this embodiment, a buffer assembly 24 is provided on the upper part of the support plate 26 towards the transfer box 1 side. The buffer assembly 24 includes a spring 241 fixed on the support plate 26, and a buffer layer 242 is fixed at the free end of the spring 241. The buffer layer 242 is made of a low-friction elastic material, and a rotating shaft 25 is rotatably connected to the top end of the support plate 26. The rotating shaft 25 is distributed along the width direction of the support plate 26. In specific use, the photovoltaic panels tilt towards the support plate. The photovoltaic panels first come into contact with the buffer layer 242. During the continuous tilting process, the spring 241 and the buffer layer 242 are compressed, and while being compressed, they generate a reverse thrust on the photovoltaic panels, enabling the photovoltaic panels to slowly lean against the support plate during the tilting process. The reverse thrust of the buffer assembly 24 plays a buffering role for the photovoltaic panels, effectively reducing the collision between the photovoltaic panels and the support plate 26 when the photovoltaic panels tilt and the friction between the photovoltaic panels and the support plate 26 when the photovoltaic panels continue to rise after tilting, and reducing the damage to the photovoltaic panels.

It should be noted that for those skilled in the art, without departing from the technical solution of the present utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicability of the patent.
