Abstract
Description
Technical Field
[0001] This utility model relates to the field of power compartment technology, and in particular to a prefabricated power compartment and its roof structure. Background Technology
[0002] With the continuous acceleration of smart grid construction, higher requirements have been placed on the construction speed and quality of power facilities such as substations. Traditional substation construction suffers from problems such as long construction cycle, low integration, and difficult maintenance, making it difficult to meet the needs of smart grid construction. In contrast, prefabricated power modules, as a new type of substation solution, have advantages such as short construction cycle, high integration, and environmental protection and energy saving. They can be quickly promoted and applied to actual construction, significantly shortening the construction cycle and improving the construction efficiency of substations, and are widely used in the power industry.
[0003] Precast power modules typically consist of a module body and a roof, which are hoisted and assembled during installation. However, the roofs of existing precast power modules usually only serve to shield the module body, which is a single function. In addition, traditional precast power modules rely on heat dissipation vents on the side walls of the module body for heat dissipation, which has poor heat dissipation effect. Therefore, this application provides a precast power module and roof structure to meet the requirements. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a prefabricated electric power cabin and its roof structure to solve the problems of poor heat dissipation and limited roof function in existing prefabricated electric power cabins.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A prefabricated electric power cabin and its roof structure includes a top frame, the bottom of which is closed, and a top cover on the top of which is provided. A first through groove is provided in the center of the bottom wall of the top frame, and a second through groove is provided at both ends of the bottom wall of the top frame. An exhaust frame is also provided at both ends of the bottom wall of the top frame, and the exhaust frame is located on the side of the second through groove away from the first through groove. An air inlet slot is provided on the side wall of the top frame at a position corresponding to the first through groove. The top frame is provided with a barrier to prevent the first through groove and the second through groove from communicating.
[0007] Optionally, the exhaust frame extends vertically through the bottom wall of the top frame, and multiple exhaust fans are installed side by side inside the exhaust frame.
[0008] Optionally, the top cover is triangular and arched upwards, with the bottom surface of the top cover aligned with and sealed to the top surface of the top frame, and the arched portion of the top cover is provided with multiple lifting rings.
[0009] Optionally, a first mesh screen is installed inside the air intake slot.
[0010] Optionally, a second mesh is installed in the first through slot, the mesh count of the second mesh being greater than that of the first mesh.
[0011] Optionally, multiple support columns are vertically fixed inside the top frame, and the top ends of the support columns are connected to the arched portion of the top cover.
[0012] Optionally, the barrier is a pair of first baffles arranged in the top frame, the pair of first baffles being distributed on both sides of the first through slot, the air inlet slot being located between the pair of first baffles, and the bottom and both ends of the first baffles being sealed and fitted to the inner wall of the top frame.
[0013] Optionally, a pair of second baffles are provided inside the top cover, the pair of second baffles being aligned and sealed with the pair of first baffles, and the second baffles being sealed and fitted to the inner wall of the top cover.
[0014] Optionally, a pair of partitions are vertically fixed at the bottom of the top frame, and the pair of partitions are aligned with a pair of first baffles.
[0015] A prefabricated electric power cabin includes a prefabricated electric power cabin body and a prefabricated electric power cabin roof structure. The top frame is fixedly assembled on the top of the prefabricated electric power cabin body. The second through slot is located inside the prefabricated electric power cabin body. The exhaust frame is located outside the prefabricated electric power cabin body. The partition is vertically inserted into the prefabricated electric power cabin body. The side wall of the partition is sealed and fitted to the inner side wall of the prefabricated electric power cabin body. A gap is left between the bottom end of the partition and the inner bottom wall of the prefabricated electric power cabin body.
[0016] Compared with the prior art, this utility model has at least the following beneficial effects:
[0017] In the above scheme, the top frame is fixedly assembled to the top of the prefabricated power pod through the air inlet slot, the first through slot, the second through slot, and the exhaust frame. The second through slot is located inside the prefabricated power pod, and the exhaust frame is located outside the prefabricated power pod. The partition is vertically inserted into the prefabricated power pod, and the side wall of the partition is sealed to the inner side wall of the prefabricated power pod. A gap is left between the bottom end of the partition and the bottom wall of the prefabricated power pod. When the multiple exhaust fans in the exhaust frame are activated, the air inside the prefabricated power pod can be drawn out through the second through slot, creating a negative pressure inside the prefabricated power pod. Outside air enters the prefabricated power pod through the air inlet slot and the first through slot, which can form an airflow circulation inside and outside the prefabricated power pod and the top frame. While the top frame and the top cover provide protection for the top of the prefabricated power pod, they can also provide ventilation and heat dissipation inside the prefabricated power pod.
[0018] The structure, with the second through slot and exhaust frame located at both ends of the bottom of the top frame, the air inlet slot and the first through slot located in the middle of the top frame, and a pair of baffles set at the bottom of the top frame, can form a U-shaped airflow trajectory from the middle to both ends in the prefabricated power cabin, ensuring that air can circulate and dissipate heat in all parts of the prefabricated power cabin, thus having good heat dissipation performance.

[0033] like Figure 2 and Figure 3As shown, an embodiment of this utility model provides a prefabricated electric cabin roof structure, including a top frame 2. The bottom of the top frame 2 is closed, and a top cover 3 is provided on the top of the top frame 2. The top cover 3 is triangular and arched upward, which is conducive to the drainage of rainwater. The arched part of the top cover 3 is provided with multiple lifting rings 5 for easy hoisting.
[0034] like Figures 2 to 4 As shown, a first through groove 7 is provided in the center of the bottom wall of the top frame 2, and a second through groove 8 is provided at both ends of the bottom wall of the top frame 2. An exhaust frame 9 is also provided at both ends of the bottom wall of the top frame 2. The exhaust frame 9 is located on the side of the second through groove 8 away from the first through groove 7. An air inlet slot 4 is provided on the side wall of the top frame 2 at the position corresponding to the first through groove 7. The top frame 2 is provided with a barrier to prevent the first through groove 7 and the second through groove 8 from communicating. The exhaust frame 9 vertically penetrates the bottom wall of the top frame 2. Multiple exhaust fans 12 are installed side by side inside the exhaust frame 9. A dustproof net is installed at the bottom of the exhaust frame 9 to prevent mosquitoes and dust from entering the exhaust frame 9. The bottom surface of the top cover 3 is aligned with the top surface of the top frame 2 and sealed. With this structure, when the exhaust fan 12 is started, the air at both ends of the top frame 2 and the top cover 3 can be drawn out. When the second channel 8 and the first channel 7 are connected to the prefabricated power compartment, the air in the prefabricated power compartment can be discharged through the second channel 8. Outside air enters the prefabricated power compartment through the air inlet 4 and the first channel 7, forming an airflow circulation to ventilate and dissipate heat for the prefabricated power compartment.
[0035] like Figures 2 to 4 As shown, a first mesh 13 is installed in the air intake slot 4, and a second mesh 14 is installed in the first through slot 7. The mesh count of the second mesh 14 is greater than that of the first mesh 13, and it is used to block external dust. Multiple support columns 10 are vertically fixed in the top frame 2, and the top of the support column 10 is connected to the arched part of the top cover 3.
[0036] like Figures 2 to 5 As shown, the barrier is a pair of first baffles 11 arranged inside the top frame 2. The pair of first baffles 11 are distributed on both sides of the first through groove 7, and the air inlet hole 4 is located between the pair of first baffles 11. The bottom and both ends of the first baffles 11 are sealed and fitted to the inner wall of the top frame 2. A pair of second baffles 15 are provided inside the top cover 3. The pair of second baffles 15 are aligned and sealed with the pair of first baffles 11. The second baffles 15 are sealed and fitted to the inner wall of the top cover 3. A pair of partitions 6 are vertically fixed at the bottom of the top frame 2. The pair of partitions 6 are aligned and fitted with the pair of first baffles 11.
[0037] like Figures 1 to 4As shown, this embodiment also provides a prefabricated power cabin, including a prefabricated power cabin body 1 and a prefabricated power cabin roof structure. The top frame 2 is fixedly assembled on the top of the prefabricated power cabin body 1. The second through slot 8 is located inside the prefabricated power cabin body 1. The exhaust frame 9 is located outside the prefabricated power cabin body 1. The partition 6 is vertically inserted into the prefabricated power cabin body 1. The side wall of the partition 6 is sealed and fitted with the inner side wall of the prefabricated power cabin body 1. A gap is left between the bottom end of the partition 6 and the inner bottom wall of the prefabricated power cabin body 1.
[0038] The working principle of the technical solution provided by this utility model is as follows:
[0039] In use, the top frame 2 is fixedly assembled to the top of the prefabricated power cabin 1, with the second through slot 8 located inside the prefabricated power cabin 1, the exhaust frame 9 located outside the prefabricated power cabin 1, and the partition 6 vertically inserted into the prefabricated power cabin 1. The side wall of the partition 6 is sealed to the inner side wall of the prefabricated power cabin 1, and a gap is left between the bottom end of the partition 6 and the inner bottom wall of the prefabricated power cabin 1. Thus, multiple exhaust fans 12 in the exhaust frame 9 are activated, drawing air out of the prefabricated power cabin 1 through the second through slot 8, creating negative pressure inside the prefabricated power cabin 1. Outside air enters the prefabricated power cabin 1 through the air inlet slot 4 and the first through slot 7. Inside, airflow circulation can be formed inside and outside the prefabricated power cabin 1 and the top frame 2. While the top frame 2 and the top cover 3 provide shelter for the top of the prefabricated power cabin 1, they can also ventilate and dissipate heat inside the prefabricated power cabin 1. Furthermore, since the second through slot 8 and the exhaust frame 9 are located at the bottom ends of the top frame 2, and the air inlet slot 4 and the first through slot 7 are located in the middle of the top frame 2, along with a pair of partitions 6 set at the bottom of the top frame 2, a U-shaped airflow trajectory from the middle to both ends can be formed inside the prefabricated power cabin 1, ensuring that air can circulate and dissipate heat at all locations inside the prefabricated power cabin 1, thus possessing good heat dissipation performance.
