Description

Technical Field

[0001] The utility model relates to the technical field of building integrated photovoltaics, and particularly relates to a vertical transportation device for photovoltaic modules. Background Art

[0002] Photovoltaics can directly convert endless solar energy into electric energy, which is a very clean energy source; especially for rooftop distributed photovoltaics, the existing rooftops of buildings can be utilized to directly install photovoltaic systems, and the electricity generated by photovoltaics can be directly utilized by the production equipment of factories.

[0003] However, for the construction of a rooftop distributed photovoltaic power station, photovoltaic modules need to be installed on the rooftop piece by piece. For a 10,000-square-meter rooftop, about 2,000 photovoltaic modules are required. The photovoltaic modules are transported to the site in a packaging unit consisting of 30 - 50 pieces; if a whole packaging unit is transported to the rooftop, a lifting device is often needed. Due to the huge number of lifting units, if the modules are laid and lifted simultaneously, high mechanical equipment costs will be incurred. If all the modules are lifted onto the rooftop at once, it will cause load accumulation on the rooftop, posing a safety hazard to the rooftop. If the photovoltaic modules are placed on the ground and transported to the rooftop one by one, it will cost a large amount of labor costs and there will also be a risk of module damage.

[0050] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work shall fall within the protection scope of the present utility model.

[0051] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0052] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0053] As Figures 1-7 shown, the present utility model provides a vertical transportation device for photovoltaic modules, including a main structural support 1 arranged vertically. An elevating platform 2 and a driving device I3 are provided on the main structural support 1. The elevating platform 2 is arranged on one side of the main structural support 1, and the driving device I3 is in driving connection with the elevating platform 2 for driving the elevating platform 2 to move up and down along the main structural support 1. On the other side of the main structural support 1, a roof platform 4 is further provided. The roof platform 4 is located above the building wall 5, and its lower end face is slightly higher than the height of the building wall 5. The elevating platform 2 is driven to rise so that the photovoltaic module transmission plane thereon and the photovoltaic module transmission plane on the roof platform 4 are at the same height. The main structural support 1 mainly consists of two columns I11. A whole is formed between the two columns 11 through a cross bar 13. To ensure the stability of the main structural support 1, diagonal bars 14 are also arranged between the two cross bars 13; As Figure 1 shown, the main structural support 1 is connected to the building wall through a wall connecting member 12, ensuring the safety of the 1-structural body. As Figure 7As shown in the figure, when the 12-connected wall member cannot be connected to the building wall 5, 4 columns I11 can be set up and then connected by the cross bar 13 to make the main structure support 1 form a stable system by itself, such as Figure 7 shown.

[0054] Place the packaged photovoltaic module on the lifting platform 2, as Figure 1 shown. Then the driving device I drives the lifting platform to rise along the column I. When it rises to be flush with the roof platform 4, stop the lifting of the lifting platform 2. Then transfer the photovoltaic module from the lifting platform to the roof platform 4, as Figure 2 shown. Then move the photovoltaic module from the roof platform 4 to the roof panel for laying. The structure of the present utility model greatly saves manpower. By combining the driving device, the lifting platform and the roof platform, the transmission of the photovoltaic module is realized quickly, greatly improving the work efficiency.

[0055] As a preferred embodiment of the present utility model, the lifting platform 2 includes a platform skeleton 21, a connecting buckle 22, a roller I23 and a guardrail 24. Multiple roller I23 are arranged at intervals and in parallel on the platform skeleton 21, as Figures 8 to 10 shown. The guardrail 24 is installed on the platform skeleton 21 in a detachable manner. Connecting buckles 22 are also installed at both sides of one end of the platform skeleton 21. The two columns I11 on the main structure support 1 penetrate through the connecting buckles 22. When the driving device I3 drives the lifting platform 2 to rise and fall, the connecting buckle 22 moves up and down along the two columns I11. The platform skeleton 21 is mainly used to support the weight of the upper photovoltaic module b and other goods. The packaged photovoltaic module can slide on the roller I23 as a whole, and the photovoltaic module b can be loaded on the lifting platform 2 by being pushed by one person; as Figure 9 shown, the lifting platform 2 is equipped with a guardrail 24 around it. This guardrail 24 is designed to be detachable. Remove the guardrail 24 before loading the goods. After the photovoltaic module b is in place, install the guardrail 24 to prevent the photovoltaic module b from tipping over.

[0056] As Figure 10 and Figure 11 shown, multiple roller I23 form a photovoltaic module transmission plane. Limit devices 25 are respectively installed at the front and rear ends of the photovoltaic module transmission plane for limiting the front and rear positions of the photovoltaic module.

[0057] When the packaged photovoltaic module b is in place on the lifting platform 2, lift the limit device 25, and the photovoltaic module b cannot move on the lifting platform 2, thus ensuring the stability of the photovoltaic module b during the vertical lifting process. When it is necessary to unload or move the photovoltaic module b, step on the limit device 25 with the foot to make it in the same plane as the platform skeleton 21. The roller I23 is slightly higher than the plane of the platform skeleton 21, so as to ensure that the photovoltaic module b can be easily unloaded.

[0058] The structure of the connection buckle 22 adopted by the utility model is as shown in Figure 13 and Figure 14 . The connection buckle 22 includes a sleeve 221 with upper and lower openings. Bearing groups 222 are respectively arranged on the opposite sides inside the sleeve 221, and the bearing groups 222 form a rolling connection with the column I11. The connection buckle 22 is sleeved on the column I11. Bearing groups 222 composed of a plurality of bearings are arranged on both sides inside the connection buckle 22. The plurality of bearings can change the sliding friction between the connection buckle 22 and the column I11 into rolling friction. At the same time, the bearing groups 222 can hold the column I11 to prevent the connection buckle 22 from falling off the column I11, and can also ensure that the connection buckle 22 is in the same vertical state to prevent jamming during the lifting process.

[0059] As shown in Figure 1 , Figure 6 , Figure 7 , the roof platform 4 includes columns II41, top crossbars 42, roller bars II43 and bottom connecting rods 44. The upper and lower ends of the columns II41 are respectively connected to the top crossbars 42 and the bottom connecting rods 44 to form a roof platform support a. A number of roller bars II43 are arranged in parallel at intervals at the upper end of the roof platform support a. The bottom connecting rod 44 is fixedly connected to the roof panel 6 through a support fixture 7. The lifting platform 2 is driven to rise so that the photovoltaic module transmission plane where the roller bar I23 is located on it is at the same height as the photovoltaic module transmission plane where the roller bar II43 is located on the roof platform 4. First, the bottom connecting rod 44 is connected through the support fixture 7 arranged on the roof panel 6. The column II41 is supported on the bottom connecting rod 44. The number of columns II41 can be set to 2 or 4 according to requirements; the top crossbar 42 is supported at the upper end of the column II. At the same time, a number of roller bars II43 are arranged between the top crossbars 42. The roof platform support a composed of the top crossbars 42 and the roller bars II43 should be slightly higher than the height of the parapet wall.

[0060] As shown in Figure 2 and Figure 3 , when the height of the building wall 5 is too high, it will cause the height of the roof platform 4 to be too large from the height of the roof panel 6. A roof lifting platform 8 can be set by means of the column II41 of the roof platform 4. Specifically, a roof lifting platform 8 is arranged inside the roof platform support a. The roof lifting platform 8 is connected to the roof platform support a through the connection buckle 22 sleeved on the column II41. The roof lifting platform 8 is also provided with a driving device II9 for driving its lifting and a number of roller bars III81 arranged in parallel at intervals. The operating principle and steps of the roof lifting platform 8 are similar to those of the lifting platform 2 and will not be elaborated here.

[0061] As shown in Figure 4 , Figure 5 andFigure 6 As shown, the driving device I3 and the driving device II9 include a driving motor 101, a cable winder 102, a traction cable 103 and a pulley 104. The cable winder 102 is arranged at the driving end of the driving motor 101. The pulleys 104 are respectively arranged at the upper part of the main structure bracket 1 and the upper part of the roof platform support a. One end of the traction cable 103 is connected to the cable winder 102, and the other end thereof bypasses the pulley 104 and is connected to the platform skeleton 21 and the roof lifting platform 8, and is used to control the lifting of the lifting platform 2 and the roof lifting platform 8 respectively.

[0062] According to different lifting loads, one or more driving motors 101 can be set. The cable winder 102 is installed at the end of the driving motor. One end of the traction cable 103 is connected to the lifting platform 2, and the other end is connected to the cable winder 102. At the same time, the traction cable 103 needs to pass through the pulley 104 at the top of the main structure bracket 1. At the same time, on the cross bar 13 at the top of the main structure bracket 1, a plurality of suspension points are set, and a plurality of pulleys 104 or anti-falling ropes 105 can be suspended. The anti-falling rope 105 has the function of falling and tensioning, preventing the traction cable 103 from falling off or breaking during use, causing the lifting platform 2 to fall; as Figure 2 and Figure 10 As shown, when the lifting platform 2 is lifted to the same height as the roof platform 4, the limit device 25 is lowered, and the packaged photovoltaic modules can be moved as a whole from the lifting platform 2 to the roof platform 4.

[0063] The utility model is simple to set up, convenient to operate, and has multiple modes, suitable for various application scenarios. Only 1-2 people are required for operation, and the photovoltaic modules of a packaging unit can be transported to the roof. Moreover, the photovoltaic modules of a packaging unit can be transported and laid as needed, which can save labor costs and mechanical costs.

[0064] The parts not described in the utility model are applicable to the prior art.

[0065] Obviously, the above embodiments are only examples given for clear illustration, and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the utility model.
