Description

Technical Field

[0001] This invention relates to dehumidification technology for transformer substations, specifically to a deep dehumidification mechanism for transformer substation foundation condensation. Background Technology

[0002] A prefabricated substation, or simply prefabricated substation, is a compact set of power distribution equipment that integrates high-voltage switchgear, distribution transformers, and low-voltage power distribution devices into one or more enclosures with windproof, rainproof, and dustproof functions according to a specific wiring scheme. It is mainly divided into European and American types. Its working principle is to receive high-voltage electrical energy in the high-voltage chamber, step it down in the transformer chamber, and then distribute it to the electrical equipment or power distribution network in the low-voltage chamber. It has the advantages of small footprint, flexible combination, low investment, short construction period, and can be integrated with intelligent monitoring system to realize "four remote" functions. However, it has problems such as the capacity of a single transformer generally does not exceed 1250kVA, high heat dissipation pressure, narrow inspection and maintenance space, and operating noise. It is widely used in urban public power distribution, residential communities, industrial parks, rail transit and other occasions.

[0003] During the operation of the transformer substation, it is necessary to dry the humid air inside, which requires the use of a condenser dehumidification mechanism. Currently, the connection between the current condenser dehumidification mechanism and the transformer substation is mostly through flanges and bolts. Although this method is simple to operate, it is time-consuming and affects work efficiency when installing and disassembling the dehumidification mechanism. At the same time, most current dehumidification mechanisms cannot adjust the residence time of air in the dehumidification chamber. When the air humidity is high, the residence time is short, which will cause the humid air to flow back before it can be fully condensed, thus causing condensation inside the transformer substation. When the air humidity is low, the residence time is long, which will increase unnecessary energy consumption.

[0004] To address the problems raised in the background art, those skilled in the art have proposed a condensation-type deep dehumidification mechanism for transformer substation foundations. Summary of the Invention

[0005] The purpose of this invention is to provide a condensation-type deep dehumidification mechanism for transformer substations, so as to solve the problems of long installation and disassembly time between the dehumidification mechanism and the transformer substation in the prior art, and the inability to adjust the residence time of air in the dehumidification chamber.

[0029] As attached Figure 1 To be continued Figure 9 As shown:

[0030] Example 1:

[0031] This invention provides a condensing deep dehumidification mechanism for a transformer substation, comprising: a transformer substation body 1; a dehumidification box 2 with an internal dehumidification chamber disposed below the transformer substation body 1; mounting brackets 3 fixedly connected to the outer periphery of both ends of the dehumidification box 2 and fixedly connected to the top of the transformer substation body 1; an air inlet 4 and an air outlet 5 respectively penetrating through both ends of the dehumidification chamber; an intake fan 6 and an exhaust fan 7 respectively installed inside the air inlet 4 and the air outlet 5; connecting pipes 8 fixedly connected to the outer ends of both the air inlet 4 and the air outlet 5; two sets of mounting pipes 9 fixedly connected to the bottom of the transformer substation body 1; an upper mounting base 10 fixedly connected to the outer periphery of the bottom of the mounting pipe 9; and a lower mounting base 11 fixedly connected to the outer periphery of the top of the connecting pipe 8; a mounting assembly 12 disposed at the connection between the upper mounting base 10 and the lower mounting base 11; the mounting assembly 12 includes a mounting groove 121, a mounting block 122, a mounting hole 123, a first connecting groove 124, and a mounting rod 12. 5. The first annular groove 126, the rotating ring 127, the first connecting block 128, the first sliding groove 129, the first slider 1210, and the first spring 1211 are fixedly installed inside the dehumidification chamber 2. Two sets of cooling plates 14 are fixedly installed inside the dehumidification chamber 2. A heat-conducting block 15 is installed on one side of the cooling plate 14. A condensation plate 16 is installed on the side of the heat-conducting block 15 away from the cooling plate 14. A heat dissipation fin 17 is installed on the side of the cooling plate 14 away from the heat-conducting block 15. An L-shaped partition 18 is fixedly connected to the bottom of the cooling plate 14 to separate the air that needs to be condensed from the heat generated during the operation of the cooling plate 14. Two sets of heat dissipation vents 19 are opened at the top of the dehumidification chamber 2 between the heat dissipation fin 17 and the partition 18. A cooling fan 20 is installed inside the heat dissipation vent 19. A guide channel 21 is opened at the bottom of the dehumidification chamber below the condensation plate 16. Two sets of drain pipes 22 connected to the guide channel 21 are installed at the bottom of the dehumidification chamber 2.

[0032] In one embodiment of the present invention, a plurality of mounting grooves 121 are provided and are formed on the top of the lower mounting base 11. A mounting block 122 is fixedly connected to the bottom of the upper mounting base 10 and is adapted to the size of the mounting groove 121. A mounting hole 123 passes through the mounting block 122. A first connecting groove 124 is formed on one inner wall of the mounting groove 121. A mounting rod 125 is slidably connected to the first connecting groove 124 and is adapted to the size of the mounting hole 123. A first annular groove 126 is formed inside the lower mounting base 11 and communicates with the bottom of the first connecting groove 124. A rotating ring 127 is rotatably connected to... In the first annular groove 126, the first connecting block 128 is fixedly connected to the top of the rotating ring 127 and the bottom of the end of the mounting rod 125 away from the mounting groove 121 and is slidably connected to the first connecting groove 124. The first sliding groove 129 is opened at the bottom of the lower mounting base 11 and communicates with the bottom of the first annular groove 126. The first slider 1210 is fixedly connected to the bottom of the rotating ring 127 and slidably connected to the first sliding groove 129. The first spring 1211 is installed inside the first sliding groove 129 and its two ends are respectively fixedly connected to one side of the first slider 1210 and one side of the inner wall of the first sliding groove 129.

[0033] Working principle: First, the first slider 1210 slides along the first groove 129 to compress the first spring 1211. During this process, the rotating ring 127 moves synchronously along the first annular groove 126 with the first slider 1210. The rotating ring 127 then drives the mounting rod 125 to move synchronously within the first connecting groove 124 via the first connecting block 128. When the mounting rod 125 moves out of the mounting groove 121 and into the first connecting groove 124, the top of the lower mounting seat 11 and the bottom of the upper mounting seat 10 are tightly pressed together, causing the mounting block 122 to be inserted into the mounting groove 121. Then, the first slider 1210 is released, and the first spring 1211 rebounds and drives the rotating ring 127 to move in the opposite direction via the first slider 1210. At this time, the first connecting block 128 drives the mounting rod 125 to move synchronously within the first connecting groove 124. The rotating ring 127 moves synchronously. When the mounting rod 125 is inserted into the mounting hole 123, the mounting block 122 can be fixed in the mounting groove 121, thus completing the connection between the mounting pipe 9 and the connecting pipe 8. Then, the intake fan 6 and the exhaust fan 7 are started, so that the humid air inside the transformer body 1 is drawn into the dehumidification chamber through the mounting pipe 9 and the connecting pipe 8. At this time, the cooling chip 14 and the cooling fan 20 are started. When the humid air comes into contact with the condensation plate 16, condensation begins. The condensed dry air flows back into the transformer body 1 through the connecting pipe 8. During this process, the water droplets generated by condensation will fall due to their own gravity and be discharged through the guide groove 21 and the drain pipe 22. The heat generated by the cooling chip 14 during operation will be discharged to the outside through the heat dissipation fins 17 and the cooling fan 20 through the heat dissipation port 19.

[0034] Example 2:

[0035] This embodiment is basically the same as the previous embodiment, except that a sealing component 13 is also provided at the connection between the upper mounting base 10 and the lower mounting base 11. The sealing component 13 includes a sealing groove 131, a second annular groove 132, a sealing ring 133, an air chamber 134, a piston 135, a connecting hole 136, a second connecting groove 137, a second connecting block 138, and a connecting rod 139.

[0036] In one embodiment of the present invention, a sealing groove 131 is formed at the bottom of the upper mounting base 10, a second annular groove 132 is formed at the top of the lower mounting base 11, a sealing ring 133 is made of rubber and is hollow inside, the sealing ring 133 is installed inside the second annular groove 132 and, after expansion, is adapted to the size of the sealing groove 131, an air chamber 134 is formed inside the lower mounting base 11, a piston 135 is slidably connected to the air chamber 134 and is adapted to the size, a connecting hole 136 is formed on the top inner wall of one side of the air chamber 134 and communicates with the sealing ring 133, a second connecting groove 137 is formed on one side of the first annular groove 126 and communicates with the half of the air chamber 134 away from the connecting hole 136, a second connecting block 138 is fixedly connected to one side of the rotating ring 127 and slidably connected to the second connecting groove 137, and a connecting rod 139 is movably connected to the air chamber 134 and its two ends are respectively fixedly connected to the second connecting block 138 and the piston 135.

[0037] Working principle: During the process of the first slider 1210 compressing the first spring 1211, the second connecting block 138 drives the piston 135 along the air chamber 134 through the connecting rod 139, sliding synchronously with the first slider 1210 and drawing air from the sealing ring 133 into the air chamber 134 through the connecting hole 136. When the sealing ring 133 deflates and is submerged in the second annular groove 132, the upper mounting seat 10 and the lower mounting seat 11 are installed. After installation, the first slider 1210 is released, causing the first spring 1211 to rebound. At this time, the first slider 1210 drives the piston 135 to move in the opposite direction in the air chamber 134 through the second connecting block 138 and the connecting rod 139, thereby sending air from the air chamber 134 into the sealing ring 133 through the connecting hole 136. When the sealing ring 133 expands to fit tightly with the sealing groove 131, the connection between the upper mounting seat 10 and the lower mounting seat 11 is sealed.

[0038] Example 3:

[0039] This embodiment is basically the same as the previous embodiment, except that a guide plate 23 with a smaller size than the dehumidification chamber is provided on the side of the condensation plate 16 away from the partition plate 18. An adjustment component 24 is provided at the bottom of the guide plate 23 where it connects to the dehumidification chamber. The adjustment component 24 includes a mounting post 241, a rotating groove 242, a rotating shaft 243, a cavity 244, a second sliding groove 245, a through groove 246, a pull rod 247, a second slider 248, a second spring 249, a slot 2410, a locking block 2411, and a pulling block 2412.

[0040] In one embodiment of the present invention, mounting posts 241 are fixedly connected to both sides of the dehumidification chamber 2, rotating grooves 242 penetrate the inner walls of both sides of the dehumidification chamber and extend into the mounting posts 241, rotating shafts 243 are fixedly connected to both sides of the bottom of the guide plate 23 and rotatably connected to the rotating grooves 242, a cavity 244 is formed inside the rotating shaft 243 on one side of the guide plate 23, a second sliding groove 245 is formed on the top and bottom inner walls of the cavity 244, a through groove 246 penetrates the inner wall of the rotating groove 242 on one side of the guide plate 23 and communicates with the cavity 244, and a pull rod 247 is movably connected to the through groove 246 and extends into the inner end. Inside the cavity 244, the second slider 248 is fixedly connected to the inner end of the pull rod 247 and slidably connected to the cavity 244 and the second slide groove 245. The second spring 249 is sleeved on the outer periphery of the pull rod 247 near the inner end and its two ends are fixedly connected to one side of the second slider 248 and one side of the inner wall of the cavity 244, respectively. The slot 2410 is opened on the surface of the mounting post 241 on one side of the guide plate 23 and is located on the outer periphery of the through groove 246. The block 2411 is fixedly connected to the outer periphery of the pull rod 247 near the outer end and is adapted to the size of the slot 2410. The pull block 2412 is fixedly connected to the outer end of the pull rod 247.

[0041] Working principle: When the air humidity is high or low, it is necessary to adjust the residence time of the air in the dehumidification chamber to ensure the condensation effect or reduce energy consumption. At this time, the pull block 2412 is pulled outward, causing it to drive the second slider 248 to slide outward along the second slide groove 245 and the cavity 244 via the pull rod 247, thus compressing the second spring 249. When the locking block 2411 moves outward with the pull rod 247 and moves out of the locking groove 2410, the pull rod 247 is rotated to drive the second slider 248 to rotate synchronously. Since the second slider 248 is slidably connected to the cavity 244 and the second slide groove 245, and the second spring 249 is compressed, the second slider 248 is compressed. Two grooves 245 are formed on the top and bottom inner walls of the cavity 244. Therefore, the second slider 248 will drive the rotating shaft 243 to rotate synchronously with the pull rod 247, thereby adjusting the angle of the guide plate 23. After adjusting to the appropriate angle, the pull block 2412 is released, the second spring 249 rebounds and drives the pull rod 247 to move inward through the second slider 248. When the locking block 2411 moves inward with the pull rod 247 to the insertion slot 2410, the pull rod 247 can be fixed at the current angle, thereby fixing the guide plate 23 at the current angle. At this time, the air residence time adjustment can be completed.

[0042] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
