Description

Technical Field

[0001] This invention relates to the field of solar photovoltaic module hoisting technology, and in particular to a hoisting and protective device for solar photovoltaic modules in mountainous areas. Background Technology

[0002] Photovoltaic modules (also called solar panels or photovoltaic modules) are the core and most important component of a solar power system. Their function is to convert solar energy into electrical energy, which is then either stored in batteries or used to power loads. The quality and cost of photovoltaic modules directly determine the quality and cost of the entire system. High-power, high-efficiency, high-reliability, and high-output modules are key to driving photovoltaic power generation towards grid parity. Furthermore, the quality of photovoltaic module installation directly affects the safety performance of the solar power plant. Improper installation can lead to instability and other safety hazards, such as fires. Therefore, high-quality photovoltaic module installation is crucial for ensuring the safety of solar power generation.

[0003] Taking the Maoergai Hydropower Station photovoltaic power generation project in Heishui County as an example, the project has a total installed capacity of 520.905 MWac and a nominal rated capacity of 420 MWac. It uses 942,396 monocrystalline silicon bifacial photovoltaic modules with peak power of 550Wp and 555Wp (425,600 550Wp modules and 516,796 555Wp modules). The project uses a large number of photovoltaic modules, so unloading and relocation of the modules is a major challenge. Since the project is located in a mountainous area with complex terrain, the use of forklifts is limited. Therefore, cranes, loaders and other mechanical equipment are used to lift and unload the modules. During the lifting process, it is often found that the lifting straps squeeze and damage the module box, resulting in module breakage.

[0004] Therefore, a lifting protection device for mountain solar photovoltaic modules is needed to prevent the lifting slings used during lifting from squeezing and damaging the module housing, which could lead to module breakage. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a lifting protection device for mountain solar photovoltaic modules to prevent the lifting slings used during lifting from squeezing and damaging the module housing, thus preventing module breakage.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A lifting and protective device for mountain solar photovoltaic modules includes: a left protective pipe and a right protective pipe; the left and right protective pipes are detachably connected; a first sleeve and a second sleeve are fixedly connected to one side of the left protective pipe; the first sleeve and the second sleeve are parallel and have a certain gap between them; a third sleeve and a fourth sleeve are fixedly connected to one side of the right protective pipe; the third sleeve and the fourth sleeve are parallel and have a certain gap between them; the diameter of the third and fourth sleeves is larger than that of the first and second sleeves, and the third and fourth sleeves are respectively fitted onto the first and second sleeves; the third and fourth sleeves are provided with a plurality of positioning holes, and the first and second sleeves are provided with limiting holes; positioning bolts are fitted onto the limiting holes and the positioning holes.

This protects the components and improves lifting safety. Furthermore, depending on the actual lifting situation (e.g., lifting two housings at once), simply remove the positioning bolts, pull the left and right protective tubes to the sides, and reinsert the positioning bolts into the positioning and limit holes to adjust the device's dimensions accordingly. It is practical, simple, and convenient; preventing damage to the housing caused by the slings during lifting. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example 1

[0023] Reference Figures 2 to 4 A lifting and protection device for mountain solar photovoltaic modules includes: a left protective pipe 1 and a right protective pipe 2; the left protective pipe 1 and the right protective pipe 2 are detachably connected; in this embodiment, the left protective pipe 1 and the right protective pipe 2 are made of circular steel pipes with a diameter of 48.3 mm and a wall thickness of 3.6 mm, which is the same steel pipes used in the scaffolding at the substation construction site, making the material easy to obtain.

[0024] Specifically, a first sleeve 11 and a second sleeve 12 are fixedly connected to one side of the left protective tube 1; the first sleeve 11 and the second sleeve 12 are parallel, and a certain gap is provided between the first sleeve 11 and the second sleeve 12; in this embodiment, the gap between the first sleeve 11 and the second sleeve 12 is 1200mm.

[0025] A third sleeve 21 and a fourth sleeve 22 are fixedly connected to one side of the right protective pipe 2; the third sleeve 21 and the fourth sleeve 22 are parallel, and there is a certain gap between the third sleeve 21 and the fourth sleeve 22; the gap between the third sleeve 21 and the fourth sleeve 22 is 1200mm. Please refer to... Figure 4The third sleeve 21 and the fourth sleeve 22 have diameters larger than the first sleeve 11 and the second sleeve 12. The third sleeve 21 and the fourth sleeve 22 are respectively fitted onto the first sleeve 11 and the second sleeve 12. The third sleeve 21 and the fourth sleeve 22 are provided with a plurality of positioning holes 23. In this embodiment, there are three positioning holes 23, which are arranged equidistantly with a gap of 400mm between them. The first sleeve 11 and the second sleeve 12 are provided with limiting holes 13. The limiting holes 13 are located on the first sleeve 11. The first and second sleeves 11 and 12 are positioned away from the left protective sleeve 1 to increase the size of cardboard boxes that the lifting and protective device for mountain solar photovoltaic modules can protect. The distance between the left protective sleeve 1 and the right protective sleeve 2 is adjustable through the first sleeve 11, the second sleeve 12, the third sleeve 21, and the fourth sleeve 22 to accommodate more cardboard box sizes. Positioning bolts 3 are fitted onto the limiting hole 13 and the positioning hole 23. The positioning bolts 3 control the distance between the left protective sleeve 1 and the right protective sleeve 2 by aligning different positioning holes 23 with the limiting hole 13. This device is simple to manufacture, uses readily available materials, is easy to use, has extremely low cost, and is reusable. In actual construction, simply place the device directly above the box and spread the lifting straps to protect the modules. This device can also be adjusted according to the actual lifting situation (such as lifting 2 boxes at once). Simply remove the positioning bolt 3, pull the left protective tube 1 and the right protective tube 2 to both sides, and reinsert the positioning bolt 3 into the positioning hole 23 and the limiting hole 13. This makes the device size easy to adjust. It is practical, simple and convenient. It prevents the component box from being crushed and damaged by the lifting slings during lifting. Example 2

[0026] Based on Example 1, please refer to Figure 1 In this embodiment, several sling limiting plates 4 are provided on the outer sides of the left protective pipe 1 and the right protective pipe 2. In this embodiment, a total of 8 sling limiting plates 4 are provided, arranged in pairs as a group. Two groups of limiting plates are provided on the left side of the left protective pipe 1, with a gap of 900mm between the two groups. Two groups of limiting plates are provided on the right side of the right protective pipe 2, with a gap of 900mm between the two groups. During hoisting, placing the slings under the sling limiting plates 4 can limit the slings and prevent slippage, improving hoisting safety.

[0027] To prevent the left protective pipe 1 and the right protective pipe 2 from sliding against the box to be hoisted, several clamping plates 5 are provided at the bottom of the left protective pipe 1 and the right protective pipe 2. The clamping plates 5 are arranged at equal intervals and are placed on the outside of the top of the box during hoisting. Example 3

[0028] Based on Examples 1 and 2, such as Figure 5As shown, to facilitate welding of the sling limiting plate 4 and the clamping plate 5, the left protective pipe 1 and the right protective pipe 2 are made of square steel pipes. In this embodiment, to prevent friction between the sling and the corner of the square steel pipe, the corner of the contact point between the sling limiting plate 4 and the sling is ground. During the installation of photovoltaic modules, the bottom of the housing may also be squeezed; therefore, in this embodiment, two sets of lifting protection devices for mountain solar photovoltaic modules are provided. The difference between the two sets is that the clamping plate 5 of one set is welded to the bottom of the left protective pipe 1 and the right protective pipe 2, while the clamping plate 5 of the other set is welded to the top of the left protective pipe 1 and the right protective pipe 2. Figure 6 As shown, during hoisting, one set of clamping plates 5 is placed at the bottom of the left protective pipe 1 and the right protective pipe 2, and the other set is placed at the bottom of the box.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Substitutions may include replacements for some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the scope of protection of this utility model.
