Description

Technical Field

[0001] This invention relates to the field of electrical cabinets, and more particularly to an electrical cabinet with a foldable solar panel. Background Technology

[0002] In the field of electrical cabinets, heat dissipation is often required for the electrical components and other heat-generating parts. This is especially true for outdoor electrical cabinets in substations, where enhanced heat dissipation equipment is essential. Because outdoor electrical cabinets are geographically dispersed and inconvenient for laying power cables, solar panels are commonly installed on the cabinets to power internal cooling equipment such as fans and water-cooling devices. However, due to the relatively small size of electrical cabinets, installation space is limited, preventing the installation of large-area solar panels. This results in limited power generation efficiency and, constrained by the energy storage efficiency of solar energy, a limited number of cooling devices can be installed within the cabinet. For outdoor electrical cabinets frequently exposed to hot environments, the heat dissipation effect is often inadequate. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an electrical cabinet with a foldable solar panel, which has high space utilization, high power generation efficiency, and high safety.

[0004] The objective of this invention can be achieved through the following technical solutions:

[0005] An electrical cabinet with foldable solar panels includes an electrical cabinet body, a protective cover, and a foldable solar panel. The protective cover is located on the top of the electrical cabinet body and has an opening. The foldable solar panel includes a base, a crossbeam, a telescopic rod, several folding units, a scissor mechanism, and a retraction adjustment cylinder. The base is fixed to the top of the electrical cabinet body and located inside the protective cover. The crossbeam is mounted on the base. The telescopic rod is horizontally mounted on the crossbeam, with its movable end connected to the telescopic rod. The retraction adjustment cylinder is hinged to the crossbeam, and its output end is connected to the scissor mechanism. The several folding units are arranged sequentially along the length of the telescopic rod. Each folding unit includes two solar panels that are hinged to each other. Both ends of the folding unit are hinged to the telescopic rod. One end of the scissor mechanism is fixed to the crossbeam, and the other end is connected to the end of the last folding unit furthest from the crossbeam.

[0006] Furthermore, the foldable solar panel is located inside a protective cover when fully folded.

[0007] Furthermore, the foldable solar panel also includes an angle adjustment cylinder, the middle of the crossbeam is hinged to the base, the angle adjustment cylinder is fixed to the base, and the output end is fixedly connected to the crossbeam.

[0008] Furthermore, the base is a lifting cylinder, and the crossbeam is hinged to the output end of the lifting cylinder.

[0009] Furthermore, the telescopic rod includes several sleeves that are sequentially connected.

[0010] Furthermore, telescopic rods are provided on both sides of the crossbeam.

[0011] Furthermore, there are multiple telescopic rods located on one side of the crossbeam.

[0012] Furthermore, multiple telescopic rods located on one side of the crossbeam are evenly spaced.

[0013] Furthermore, the protective cover has bidirectional openings.

[0014] Furthermore, the protective cover has a U-shaped cross-section.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The base of the present invention is fixed inside the protective cover, the crossbeam is set on the base, the telescopic rod is set horizontally on the crossbeam, the movable end of the telescopic rod is connected, the retraction adjustment cylinder is hinged on the crossbeam, and the output end is connected to the scissor mechanism. Several folding units are arranged sequentially along the length of the telescopic rod. Each folding unit includes two solar panels that are hinged to each other. Both ends of the folding unit are hinged to the telescopic rod. One end of the scissor mechanism is fixed on the crossbeam, and the other end is connected to the end of the last folding unit away from the crossbeam. The foldable solar panel can be used with a light intensity sensor. When sunlight is detected, the retraction adjustment cylinder drives the scissor mechanism to unfold, and the scissor mechanism drives the solar panel to extend out of the protective cover until it is fully unfolded. When sunlight is not detected, the retraction adjustment cylinder drives the scissor mechanism to retract, and the scissor mechanism drives the solar panel to move closer to the protective cover until it is fully inside the protective cover. The space utilization rate is high, the capacity of the solar panel is expanded, and the power generation efficiency is improved. Thus, more electrical cabinet heat dissipation equipment can be driven. At the same time, the foldable solar module can be fully protected, and the safety is high.

[0017] (2) The present invention drives the solar panel to fold and retract by means of a shrink adjustment cylinder and a scissor mechanism. Due to the structural characteristics of the scissor mechanism, a small displacement of the output end of the shrink adjustment cylinder can cause the scissor mechanism to produce a large displacement, thereby increasing the capacity of the solar panel.

[0018] (3) The foldable solar module of the present invention also includes an angle adjustment cylinder. The middle part of the crossbeam is hinged to the base. The angle adjustment cylinder is fixed on the base and the output end is fixedly connected to the crossbeam. The angle of the crossbeam can be adjusted by the angle adjustment cylinder, thereby adjusting the angle of the solar panel, so that the foldable solar module has the function of chasing the sun and improving the power generation efficiency.

[0019] (4) The present invention has telescopic rods on both sides of the crossbeam 34, and the protective cover has a two-way opening. The foldable solar panel can be unfolded towards both sides of the crossbeam. There are multiple telescopic rods on one side of the crossbeam. The multiple telescopic rods on one side of the crossbeam are evenly spaced, which has high space utilization, can accommodate more solar panels, and has high power generation efficiency.

[0020] (5) The base of the present invention is a lifting cylinder, and the crossbeam is hinged to the output end of the lifting cylinder. Through the dual action of the lifting cylinder and the angle adjustment cylinder, the angle range of the crossbeam is expanded. Attached Figure Description

[0028] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. These embodiments are based on the technical solution of the present invention and provide detailed implementation methods and specific operating procedures. However, the scope of protection of the present invention is not limited to the following embodiments.

[0029] Example 1

[0030] An electrical cabinet with foldable solar panels, such as Figure 1 and Figure 2 It includes an electrical cabinet body 1, a protective cover 2, and a foldable solar panel 3. The protective cover 2 is located on the top of the electrical cabinet body 1 and has an opening, such as... Figure 4The foldable solar panel 3 includes a base 31, a crossbeam 34, a telescopic rod 37, several folding units, a scissor mechanism 35, and a retraction adjustment cylinder 33. The base 31 is fixed to the top of the electrical cabinet body 1 and located inside the protective cover 2. The crossbeam 34 is mounted on the base 31, and the telescopic rod 37 is horizontally mounted on the crossbeam 34. The movable end of the telescopic rod 37 is connected to the crossbeam 34, and the retraction adjustment cylinder 33 is hinged to the crossbeam 34, with its output end connected to the scissor mechanism 35. Several folding units are arranged sequentially along the length of the telescopic rod 37. Each folding unit includes two hinged solar panels 36. Both ends of the folding unit are hinged to the telescopic rod 37. Figure 5 One end of the scissor mechanism 35 is fixed to the crossbeam 34, and the other end is connected to the end of the last folding unit away from the crossbeam 34.

[0031] When the foldable solar module 3 is fully folded, it is located inside the protective cover 2. The protective cover 2 plays a protective role and has a compact structure to prevent the foldable solar module 3 from being damaged under the influence of severe weather.

[0032] The telescopic rod 37 includes several sleeves that are connected in sequence.

[0033] Telescopic rods 37 are provided on both sides of the crossbeam 34. The protective cover 2 has a two-way opening. The foldable solar module 3 can be unfolded towards both sides of the crossbeam 34. There are multiple telescopic rods 37 on one side of the crossbeam 34. The multiple telescopic rods 37 on one side of the crossbeam 34 are evenly spaced, which has a high space utilization rate and can accommodate more solar panels 36, resulting in high power generation efficiency.

[0034] The working principle of an electrical cabinet with foldable solar panels is as follows:

[0035] The foldable solar panel can be used with a light intensity sensor. When sunlight is detected, the retraction adjustment cylinder 33 drives the scissor mechanism 35 to unfold, and the scissor mechanism 35 drives the solar panel 36 to extend out of the protective cover 2 until it is fully unfolded. When sunlight is not detected, the retraction adjustment cylinder 33 drives the scissor mechanism 35 to retract, and the scissor mechanism 35 drives the solar panel 36 to move closer to the protective cover 2 until it is fully inside the protective cover 2.

[0036] Example 2

[0037] In this embodiment, the foldable solar module 3 also includes an angle adjustment cylinder 32. The crossbeam 34 is hinged to the base 31 in the middle. The angle adjustment cylinder 32 is fixed to the base 31 and its output end is fixedly connected to the crossbeam 34. The angle of the crossbeam 34 can be adjusted by the angle adjustment cylinder 32, thereby adjusting the angle of the solar panel 36, so that the foldable solar module 3 has a sun-chasing function and improves the power generation efficiency.

[0038] like Figure 3The protective cover 2 has a U-shaped cross-section to avoid spatial conflicts when the foldable solar module 3 is adjusted.

[0039] Everything else is the same as in Example 1.

[0040] Example 3

[0041] In this embodiment, the base 31 is a lifting cylinder, and the crossbeam 34 is hinged to the output end of the lifting cylinder. Through the combined action of the lifting cylinder and the angle adjustment cylinder 32, the angle range of the crossbeam 34 is expanded. Everything else is the same as in embodiment 2.

[0042] Examples 1, 2, and 3 propose an electrical cabinet with a foldable solar panel. The foldable solar panel can be used in conjunction with a light intensity sensor. When sunlight is detected, the retraction adjustment cylinder 33 drives the scissor mechanism 35 to unfold, and the scissor mechanism 35 drives the solar panel 36 to extend out of the protective cover 2 until it is fully unfolded. When sunlight is not detected, the retraction adjustment cylinder 33 drives the scissor mechanism 35 to retract, and the scissor mechanism 35 drives the solar panel 36 to move closer to the protective cover 2 until it is fully inside the protective cover 2. By using the retraction adjustment cylinder 33 and the scissor mechanism 35 to fold and retract the solar panel 36, due to the structural characteristics of the scissor mechanism 35, a small displacement of the output end of the retraction adjustment cylinder 33 can cause a large displacement of the scissor mechanism 35, thereby increasing the capacity of the solar panel.

[0043] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
