TECHNICAL FIELD

[0001] The present application relates to the field of photovoltaic technology, in particular to a photovoltaic module bottom tray structure for photovoltaic shelter. BACKGROUND

[0002] Solar energy as a renewable clean energy is increasingly expanding in life and industrial application fields, but the traditional solar photovoltaic module and support are usually large in size, which is not conducive to mobility, so the emergence of photovoltaic shelter solves this problem, and the photovoltaic shelter can be folded and moved with the photovoltaic shelter to meet the use requirements in special environment. Therefore, in the use process of the photovoltaic shelter, it is normal for the photovoltaic module to frequently enter and exit the photovoltaic shelter.

[0003] At present, in the use process of the photovoltaic shelter, all photovoltaic modules enter and exit the shelter by the cooperation of multiple people. Although the photovoltaic modules in the shelter are much smaller in size, the weight is not reduced due to the folding type, so it is difficult to enter and exit the shelter, and usually multiple people are needed to operate to put the photovoltaic module into the shelter. When the photovoltaic module is unfolded outward, multiple people are also needed to pull it, which is time-consuming and laborious. Due to the small space in the shelter, jamming is easy to occur during the pushing and pulling process, causing damage to the photovoltaic module. In addition, long-term entry and exit of the shelter causes serious wear and tear at the bottom of the shelter and the bottom of the photovoltaic module, greatly shortening the service life of the photovoltaic module and the shelter, and further increasing the maintenance and replacement cost.

[0025] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0026] like Figures 1-3 As shown, an embodiment of the present invention provides a bottom tray structure for photovoltaic modules in a photovoltaic cabin, comprising: a base plate assembly 1, partitions 2, and a rolling assembly 3. The base plate assembly 1 includes a base plate 11 and four surrounding plates 12 respectively vertically arranged around the base plate 11. At least one of the surrounding plates 12 is hinged to the base plate 11, having a surrounding state that is vertical relative to the base plate 11 and a folded-down state that forms a slope below the base plate 11. The surrounding plates 12 can switch between the folded-down state and the surrounding state. The partitions 2 are fixed to the base plate 11 at intervals, and the partitions 2 form an area for accommodating photovoltaic modules. The rolling assembly 3 is rotatably inserted through the partitions 2.

[0027] The application comprises a bottom plate assembly 1, a partition plate 2 and a rolling assembly 3, the bottom plate assembly 1 comprises a bottom plate 11 and four surrounding plates 12 vertically arranged around the bottom plate 11, the partition plate 2 forms an area for accommodating photovoltaic modules, when the surrounding plates 12 are in the surrounding state, the photovoltaic modules can be better limited in the bottom plate assembly 1, when the surrounding plates 12 are in the down state, the photovoltaic modules in the bottom plate assembly 1 can be moved relative to the bottom plate 11 through the rolling assembly 3 and slide out along the inclined partition plate 2. The rolling assembly 3 can reduce the friction between the photovoltaic modules and the bottom plate 11, effectively protect the photovoltaic modules and prolong the service life of the photovoltaic modules.

[0028] Specifically, the bottom plate 11 is plate-shaped and made of rigid material.

[0029] Specifically, the surrounding plate 12 prevents the photovoltaic modules from sliding out of the bottom plate 11 or being not accommodated in place, and limits the photovoltaic modules. It should be noted that the surrounding plate 12 is divided into a fixed surrounding plate 121 fixed to the bottom plate 11 and a movable surrounding plate 122 hinged to the bottom plate 11, one side of the movable surrounding plate 122 is hinged to the bottom plate 11 through a hinge 13, the movable surrounding plate 122 has a surrounding state vertically relative to the bottom plate 11 and a down state forming an inclined surface lower than the bottom plate 11, and can be switched between the down state and the surrounding state.

[0030] It should be noted that there are many ways to switch between the down state and the surrounding state of the movable surrounding plate 122. In some feasible embodiments, the two ends of the movable surrounding plate 122 are provided with fixed holes matched with the ends of the adjacent fixed surrounding plate 121, when the movable surrounding plate 122 is vertical relative to the bottom plate 11, the two ends of the adjacent fixed surrounding plate 121 are clamped with the fixed holes on the movable surrounding plate 122 to maintain the movable surrounding plate 122 in the surrounding state, and when it is needed to switch to the down state, the two ends of the adjacent movable surrounding plate 122 are separated from the fixed holes on the movable surrounding plate 122, and the movable surrounding plate 122 is down under the action of the thrust force to form the down state.

[0031] In this embodiment, the hinge 13 is a rotating torque hinge with a large opening and closing range and can stay at any angle, so it is not necessary to additionally provide a fixing structure, when the opening and closing angle of the movable surrounding plate 122 relative to the horizontal plane is 90°, the surrounding state is reached, and when the movable surrounding plate 122 is lower than the horizontal plane and inclined, the down state is reached.

[0032] Specifically, the partition plates 2 are fixed on the bottom plate 11 with a spacing matching the width of the photovoltaic module. The partition plates 2 are provided with through holes 21 for the rolling assembly 3 to pass through.

[0033] In addition, the height of the partition plates 2 is the same as that of the surrounding plates 12, for limiting the photovoltaic module.

[0034] Specifically, the rolling assembly 3 comprises a shaft body 31 and a roller sleeve 32. The shaft body 31 passes through the partition plates 2 and is fixed at both ends to the surrounding plates 12. The roller sleeve 32 movably sleeves the shaft body 31 and is located between the partition plates 2. The photovoltaic module is placed on the roller sleeve 32. When the photovoltaic module is pulled, the roller sleeve 32 rotates relative to the shaft body 31, which can reduce the friction at the bottom of the photovoltaic module and effectively protect the bottom of the photovoltaic module.

[0035] Further, the shaft body 31 is a straight-through solid steel column with a smooth surface. The shaft body 31 is provided with grooves 311 at both ends. The surrounding plates 12 at both ends of the shaft body 31 are provided with protrusions matching the grooves 311, which are designed to prevent the guide shaft from shifting.

[0036] Further, the roller sleeve 32 is a hollow cylinder with a length slightly smaller than the spacing between the partition plates 2 and an inner diameter matching the outer diameter of the shaft body 31, so as to produce good transmission.

[0037] Further, the shaft body 31 and the roller sleeve 32 are made of high-strength steel, which not only guarantees the strength but also reduces the overall structure weight. Considering the installation space and practicability, the outer diameter of the shaft body 31 is preferably within the range of 30mm to 36mm.

[0038] Further, the rolling assembly 3 further comprises a felt, which is attached to the surface of the roller sleeve 32 and plays a role of shock absorption, which can effectively protect the bottom of the photovoltaic module.

[0039] The specific work flow of the application: before the photovoltaic module is taken out of the photovoltaic shelter, the hinge 13 on the structure is opened, and the movable coaming 122 is lowered. One person pushes the photovoltaic module along the movable coaming 122 to lower and unfold it for use. After use, the photovoltaic module is pushed into the small partition in the tray along the movable coaming 122 by one person. The structure of the application enables the relatively heavy photovoltaic module to be quickly taken in and out of the shelter by one person, greatly shortening the preparation time of the photovoltaic module in special use environments such as war, without the need for a large number of personnel on site, saving manpower and resources, and ensuring the safety of the photovoltaic module in use. Secondly, the structure design effectively protects the bottom of the photovoltaic shelter and the bottom of the photovoltaic module, greatly reducing the degree of bottom wear and tear and improving the service life of the photovoltaic module and the photovoltaic shelter.

[0040] The application has the following beneficial effects:

[0041] The application comprises a bottom plate assembly, a partition plate and a rolling assembly. The bottom plate assembly comprises a bottom plate and four coamings vertically arranged around the bottom plate. The partition plate forms an area for accommodating the photovoltaic module. When the coamings are in the surrounding state, the photovoltaic module can be better limited in the bottom plate assembly. When the coamings are in the turned-down state, the photovoltaic module in the bottom plate assembly can move relative to the bottom plate through the rolling assembly and slide out along the inclined partition plate. The rolling assembly can reduce the friction between the photovoltaic module and the bottom plate, effectively protect the photovoltaic module and prolong the service life of the photovoltaic module.

[0042] The above is only the preferred specific embodiment of the application, but the protection scope of the application is not limited thereto. Any changes or replacements within the technical range disclosed by the application can be easily thought of by those skilled in the art, which should be covered within the protection scope of the application.
