Description

Technical Field

[0001] This utility model relates to the field of substation cabin insulation technology, and in particular to a prefabricated cabin-type substation cabin insulation structure. Background Technology

[0002] Prefabricated modular substation enclosures are integrated outdoor substation facilities that are prefabricated in a factory and assembled on-site. After the components are assembled and tested in the factory, the entire enclosure is transported to the site. They are characterized by standardization, modularity, and prefabrication, significantly shortening the construction cycle. Insulation is required because substation equipment generates heat during operation, and the external ambient temperature fluctuates greatly. Insulation reduces heat loss or transfer, maintaining a suitable operating temperature for the equipment inside the enclosure and preventing excessively high or low temperatures from affecting equipment performance and lifespan. It also prevents condensation inside the enclosure, reducing the risk of electrical short circuits and equipment corrosion, improving energy efficiency, and lowering operating costs.

[0003] Most substation enclosure insulation structures employ insulation layers in the walls, roof, and floor, along with multiple layers including waterproofing, moisture-proofing, and protective layers. They also rely on tight seals for doors and windows. However, in severe weather, such as rain, rainwater continuously washes over the top of the substation enclosure. Furthermore, drainage channels become clogged with leaves and other debris, leading to water accumulation. Because water has a high specific heat capacity, it rapidly absorbs and conducts heat, causing the top of the enclosure to remain at a low temperature, resulting in poor insulation performance.

[0004] Therefore, it is necessary to provide a new type of prefabricated substation body insulation structure to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a prefabricated substation body insulation structure.

[0006] This utility model provides a prefabricated substation body insulation structure, comprising: a substation body body, a transmission assembly, a limiting assembly, and a motor. A base is fixedly connected to the bottom of the substation body body. An access door is installed at one end of the substation body body, and multiple ventilation holes are opened at the other end of the substation body body. Two support plates are fixedly connected to the top of the substation body body. A first threaded rod is rotatably connected to the adjacent side of the two support plates. A first threaded block is threadedly connected to the outer side of the first threaded rod. A waterproof cloth is fixedly connected to the top of the first threaded block. A transmission assembly is installed on the outer side of the first threaded rod near the first threaded block. Limiting assemblies are installed inside the front and rear sides of the substation body body. A motor is fixedly connected to the side of the substation body near the access door. A storage groove is opened inside the top of the substation body body, and a solar panel is rotatably connected to one side of the inner wall of the storage groove.

[0007] Preferably, the transmission assembly includes a drive wheel, the interior of which is fixedly connected to the exterior of the first threaded rod near the first threaded block. A driven wheel is rotatably connected to the top of the substation body near the entrance / exit. A pulley is fitted around the drive wheel and the driven wheel. A first gear is fixedly connected to the end of the driven wheel away from the motor. A second gear is rotatably connected to the interior of the substation body near the entrance / exit. A second threaded rod is fixedly connected to the side of the second gear away from the motor. A second threaded block is threadedly connected to the exterior of the second threaded rod. An adjusting rod is rotatably connected to the top of the second threaded block.

[0008] Preferably, the limiting component includes a fixing rod, the two fixing rods are respectively fixedly connected to the inside of both sides of the substation cabin body, the fixing rods are slidably connected to a sliding block, and the two sliding blocks are fixedly connected to a connecting block on their opposite sides.

[0009] Preferably, the first gear and the second gear are meshed, and the driving end of the motor is fixedly connected to one side of the driven wheel.

[0012] Preferably, the outer top of the adjusting rod is rotatably connected to the inner bottom of the solar panel.

[0013] Preferably, the bottom end of the waterproof fabric is fixedly connected to the top end of the connecting block.

[0014] Compared with related technologies, the prefabricated substation body insulation structure provided by this utility model has the following beneficial effects:

[0015] By starting the motor, the waterproof cloth can be unfolded in time when it rains, building a reliable rainproof barrier for the substation cabin. This prevents rainwater from directly washing over the top of the cabin, reducing the possibility of water accumulation and preventing the cabin top from becoming cold and the insulation effect from decreasing due to water accumulation. It also prevents the insulation material from getting damp and affecting its insulation performance, reducing heat loss or transfer from inside the cabin and helping to maintain a suitable operating temperature for the equipment inside.

[0016] While unfolding the waterproof cloth, the solar panels can be automatically stored in the storage slot, preventing them from being damaged by rainwater erosion or external impacts in rainy weather, thus extending their service life and ensuring that they can work normally and efficiently under suitable weather conditions, providing a stable energy supply for the substation. When the waterproof cloth is retracted, the solar panels automatically come out, allowing them to quickly enter working condition, maximizing the capture of sunlight and continuously converting solar energy into electrical energy.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0025] Please see Figures 1 to 5A prefabricated substation cabin insulation structure is disclosed. The structure comprises: a substation cabin body 1, providing reliable space for internal equipment; a base 2 fixedly connected to the bottom of the substation cabin body 1 to effectively support its weight; an access door 3 installed at one end of the substation cabin body 1, providing convenient access for daily maintenance and equipment repair; and multiple ventilation holes 4 at the other end of the substation cabin body 1 to ensure a certain degree of airtightness of the cabin. Under the premise of achieving air circulation between the cabin and the outside, two support plates 5 are fixedly connected to the top of the substation cabin body 1 to provide additional support. A first threaded rod 6 is rotatably connected to the adjacent side of the two support plates 5. A first threaded block 7 is threadedly connected to the outside of the first threaded rod 6. A waterproof cloth 8 is fixedly connected to the top of the first threaded block 7. When the first threaded rod 6 rotates, the first threaded block 7 will move linearly along the outside of the first threaded rod 6 according to the interaction of the threads. This movement can stably drive the waterproof cloth 8 connected to it to expand or contract.

[0026] The transmission assembly includes a drive wheel 9, which is fixedly connected to the outside of the first threaded rod 6 near the first threaded block 7. The drive wheel 9 can transmit the power from the driven wheel 10 to the first threaded rod 6. A driven wheel 10 is rotatably connected to the top of the substation body 1 near the door 3. A pulley 11 is fitted around the drive wheel 9 and the driven wheel 10 to smoothly transmit the rotation of the driven wheel 10 to the drive wheel 9, ensuring the stability and continuity of power transmission. Limiting assemblies are installed inside the front and rear sides of the substation body 1. The limiting assemblies include fixed rods 12, which are fixedly connected to the outside of the two sides of the substation body 1. Sliding blocks 13 are slidably connected to the outside of the fixed rods 12. During the unfolding or retraction of the waterproof cloth 8, the sliding blocks 13 slide along the fixed rods 12 to ensure the waterproof cloth 8 moves smoothly. The direction is stable and there will be no deviation or shaking. The two sliding blocks 13 are fixedly connected to the opposite side of the connecting block 14. The bottom end of the waterproof cloth 8 is fixedly connected to the top end of the connecting block 14. The motor 15 is fixedly connected to one side of the driven wheel 10. The end of the driven wheel 10 away from the motor 15 is fixedly connected to the first gear 16. The substation body 1 is rotatably connected to the inside of the side near the door 3. The first gear 16 and the second gear 17 are meshed. The second gear 17 rotates in the opposite direction under the drive of the first gear 16, realizing the power direction transmission. The side of the second gear 17 away from the motor 15 is fixedly connected to the second threaded rod 18. The first threaded rod 6 and the second threaded rod 18 rotate in opposite directions. The second threaded rod 18 is externally threaded to the second threaded block 19. The second threaded rod 18 rotates under the drive of the second gear 17, thereby realizing the drive of the second threaded block 19. The top end of the second threaded block 19 is rotatably connected to the adjusting rod 20.

[0027] A motor 15 is fixedly connected to the side of the substation body 1 near the entrance / exit door 3. A storage slot 21 is opened inside the top of the substation body 1. A solar panel 22 is rotatably connected to one side of the inner wall of the storage slot 21, realizing the unfolding and storage of the solar panel 22. The storage slot 21 provides a safe storage space for the solar panel 22. The solar panel 22 is usually tilted to efficiently receive solar energy. The top of the adjusting rod 20 is rotatably connected to the bottom of the solar panel 22. A sliding hole 23 is opened inside the top of the substation body 1. The end of the second threaded rod 18 is rotatably connected to one side of the sliding hole 23. The outside of the second threaded block 19 is slidably connected to the inside of the sliding hole 23.

[0028] The working principle of the prefabricated substation body insulation structure provided by this utility model is as follows:

[0029] The solar panel 22 is tilted during normal times to efficiently receive solar energy, while the waterproof cloth 8 is in a retracted state when encountering rainy weather.

[0030] First, start the motor 15. Once the motor 15 starts running, it will drive the driven wheel 10 to rotate smoothly. The rotation of the driven wheel 10, through the transmission of the belt pulley 11, drives the driving wheel 9 to rotate synchronously. As the driving wheel 9 rotates, the first threaded rod 6 begins to rotate at a constant speed between the two support plates 5. Due to the interaction of the threads, the rotation of the first threaded rod 6 is converted into the linear motion of the first threaded block 7. The first threaded block 7 moves forward linearly along the outside of the first threaded rod 6.

[0031] As the first threaded block 7 moves, the waterproof cloth 8 connected to it is gradually unfolded. At the same time, to ensure the stability of the unfolding process of the waterproof cloth 8, the connecting block 14 synchronously drives the sliding block 13 to slide outside the fixed rod 12, providing support for the unfolding of the waterproof cloth 8.

[0032] As the driven wheel 10 rotates, it also drives the first gear 16, which is coaxial with it, to rotate as well. Since the first gear 16 and the second gear 17 are meshed, the rotation of the first gear 16 immediately drives the second gear 17 to rotate in the opposite direction. As the second gear 17 rotates, the rotating shaft 18 connected to it begins to rotate inside the sliding hole 23. It is worth noting that the rotation directions of the rotating shaft 18 and the first threaded rod 6 are exactly opposite. Driven by the rotation of the rotating shaft 18, the second threaded rod 19 begins to slide precisely inside the sliding hole 23. As the second threaded rod 19 slides, the adjusting rod 20 connected to it begins to move, and the movement of the adjusting rod 20 further drives the solar panel 22 to rotate smoothly inside one side of the storage slot 21. Finally, the solar panel 22 slowly returns to the inside of the storage slot 21, completing the storage process. At this time, the waterproof cloth 8 is fully unfolded, successfully protecting the substation cabin from rain, ensuring that the equipment inside the cabin is not affected by rainwater, and ensuring the stable operation of the substation under severe weather conditions.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
