[0012] Compared with the prior art, the present invention provides a modular substation ventilation and heat dissipation device, which has the following beneficial effects:

[0013] In the present invention, through the structural design of the heat dissipation device, when the air pump is started, the pure gas in the side box enters the upper housing cover 1 through the first strip opening, penetrates the filter belt and enters the lower housing cover 1. At this time, the pure gas and its flow direction cooperate with the brush for cleaning, so that the dust on the filter belt that falls off during cleaning can fall off and be discharged from the inside to the outside, thereby improving the cleaning effect, cleaning efficiency and cleaning quality of the filter belt. Then, the gas enters the filter plate again for filtration, and then enters the upper housing cover through the diversion box and the first connecting pipe.

[0014] In the present invention, the inhaled gas is filtered by the filter belt, so as to ensure the purity of the gas in the side box cavity, and further ensure that the gas blown to the surface of the substation equipment is pure gas, avoiding the accumulation of dust on the surface of the substation equipment. In addition, when the gas outside the side box enters the side box through the filter belt, it will cause the gas in the outer casing to enter the side box first, thereby reducing the contact rate between the gas in the outer casing and the substation equipment, and further reducing the degree of dust accumulation on the surface of the substation equipment, so as to ensure the cleanliness of the surface of the substation equipment during the ventilation and heat dissipation process of the substation equipment.

[0015] In the present invention, through the setting of the air pump in cooperation with the humidity control mechanism, the humidity of the gas outside the substation equipment can be flexibly controlled. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Refer to Figures 1-6, the present invention provides a technical solution: a modular substation ventilation and heat dissipation device, including a suspension rod 2, substation equipment 4, and an outer casing 1. The substation equipment 4 is arranged inside the outer casing 1. The upper end of the suspension rod 2 is connected to the top of the outer casing 1, and the lower end of the suspension rod 2 is installed with a heat dissipation device 3. The heat dissipation device 3 includes a side box 31 connected to the lower end of the suspension rod 2. Rotary rollers 312 perpendicular to the side surface of the outer casing 1 are respectively installed at the four corner ends of the side box 31. A filter belt 33 is arranged outside the side box 31 and installed outside the four rotary rollers 312. One rotary roller 312 is connected to the output end of a first motor 314 through a first transmission belt 313. A through port 311 corresponding to the filter belt 33 is arranged on the side box 31. A blowing air pipe 32 communicating with the cavity of the side box 31 is installed on the box surface of the side box 31 close to one side of the outer casing 1. A rotating shaft rod 321 is rotatably installed on the box surface of the side box 31 far from one side of the outer casing 1. One end of the rotating shaft rod 321 is installed with a first guide fan 322 placed in the blowing air pipe 32. The other end of the rotating shaft rod 321 is connected to the output end of a second motor 323 through a second transmission belt 324. The second motor 323 and the first motor 314 are respectively installed on the side box 31. A dehumidifying mechanism 6 for drying the filter belt 33 and a cleaning mechanism 5 for cleaning the filter belt 33 are also installed on the side box 31. Specifically, when the first motor 314 drives the first transmission belt 313 to drive the rotary roller 312 to rotate, the filter belt 33 can be driven to rotate. When the second motor 323 drives the second transmission belt 324 to drive the rotating shaft rod 321 to rotate, the first guide fan 322 can be driven to rotate. During this process, the first guide fan 322 extracts the gas in the cavity of the side box 31 and blows it to the surface of the substation equipment 4 through the blowing air pipe 32. At the same time, the gas outside the side box 31 is inhaled into the side box 31 through the filter belt 33, and the filter belt 33 filters the inhaled gas, thereby ensuring the purity of the gas in the cavity of the side box 31, and further ensuring that the gas blown to the surface of the substation equipment 4 is pure gas, avoiding dust accumulation on the surface of the substation equipment 4. In addition, when the gas outside the side box 31 enters the inside of the side box 31 through the filter belt 33, the gas in the outer casing 1 will preferentially enter the side box 31, thereby reducing the contact rate between the gas in the outer casing 1 and the substation equipment 4, and further reducing the degree of dust accumulation on the surface of the substation equipment 4, so as to ensure the cleanliness of the surface of the substation equipment 4 during the ventilation and heat dissipation process of the substation equipment.

[0024] In this embodiment, a second recess 317 is provided at the lower end of the side box 31. A second strip opening 318 communicating with the cavity of the side box 31 is provided on the second recess 317. The dehumidifying mechanism 6 includes second housing covers 61 disposed on both sides of the filtering surface of the filtering belt 33. A semiconductor heat sink 62 is installed on the second housing covers 61. The upper second housing cover 61 is installed in the recess 317. The heating surface of the upper semiconductor heat sink 62 is located inside the second housing cover 61. The cooling surface of the upper semiconductor heat sink 62 is located in the second strip opening 318. The lower end of the lower second housing cover 61 is communicated with a dehumidifying box 63. A dehumidifying cotton block 64 is installed in the dehumidifying box 63. An outer housing box 65 is provided outside the lower second housing cover 61. The cavity of the outer housing box 65 is connected to an air pump 67 through a second connecting pipe 66. The output end of the air pump 67 is connected to the cavity of the side box 31. A humidity control mechanism 7 is further installed on the lower second housing cover 61. Specifically, the running direction of the filtering belt 33 sequentially passes through the dehumidifying mechanism 6 and the cleaning mechanism 5. That is to say, when processing the filtering belt 33, the filtering belt 33 is first processed by the dehumidifying mechanism 6, and then the dehumidified filtering belt 33 is cleaned by the cleaning mechanism 5. Specifically, the space where the filtering belt 33 is located within the range of the second housing cover 61 is heated by the heating surface of the semiconductor heat sink 62. The gas introduced through the first connecting pipe 58 enters the upper second housing cover 61, then penetrates through the filtering belt 33 and enters the lower second housing cover 61, and then is introduced into the dehumidifying cotton block 64 for dehumidification treatment. At the same time, the cooling surface of the upper semiconductor heat sink 62 can cool the gas in the cavity of the side box 31, reducing the temperature of the gas in the side box 31. The cooling surface of the lower semiconductor heat sink 62 can cool the gas in the outer housing box 65, so that the air pump 67 sucks the cooled gas in the outer housing box 65 into the cavity of the side box 31. Then, the cold air in the side box 31 is blown towards the power transformation equipment 4 by the first guide fan 322 for temperature reduction and heat dissipation treatment.

[0025] In this embodiment, the humidity control mechanism 7 includes a diversion block 71 disposed at the connection end between the dehumidification box 63 and the lower housing cover 61. A diversion port 72 is provided in the diversion block 71. A heat conduction rod 73 also penetrates through the diversion block 72. A disc 74 is rotatably installed at the upper end of the heat conduction rod 73. The disc 74 is connected to the lower housing cover 61 by a second spring 75. The lower end of the heat conduction rod 73 penetrates through the dehumidifying sponge block 64. An adiabatic sleeve 76 is sleeved on the outer part of the heat conduction rod 73 at the position of the dehumidifying sponge block 64. A second diversion fan 77 is installed on the heat conduction rod 73 below the dehumidifying sponge block 64. A blocking block 78 is also installed in the dehumidification box 63 below the dehumidifying sponge block 64. A through hole 79 corresponding to the second diversion fan 77 is provided in the blocking block 78. Specifically, when the gas outside the power transformation equipment 4 requires a certain humidity content, it is regulated by the humidity control mechanism 7. Specifically, by increasing the power of the air pump pipe 67, a greater thrust can be generated on the second diversion fan 77, thereby driving the second diversion fan 77 to move downward. At this time, the heat conduction rod 73 at the position of the diversion block 71 enters the dehumidifying sponge block 64. At this time, the heat conduction rod 73 heats the dehumidifying sponge block 64. That is to say, the heat conduction rod 73 absorbs the heat in the housing cover 61 and conducts it to the dehumidifying sponge block 64 to slightly evaporate the moisture in the dehumidifying sponge block 64, thereby increasing the humidity of the gas outside the power transformation equipment 4 until the required humidity requirement is reached. After completion, by reducing the power of the air pump 67, the humidity control mechanism 7 can be closed, and the operation is flexible and efficient.

[0026] In this embodiment, a first recess 315 is provided at the lower end of the side box 31. A first strip opening 316 communicating with the cavity of the side box 31 is provided on the first recess 315. The cleaning mechanism 5 includes housing covers 51 disposed on both sides of the filtering surface of the filtering belt 33. A first spring 52 pointing to the filtering belt 33 is installed in the housing cover 51. A hole plate 53 is installed at the end of the first spring 52 close to the filtering belt 33. A brush 54 for cleaning the filtering belt 33 is installed on the hole plate 53. The upper housing cover 51 is installed on the first recess 315. The inner cavity of the upper housing cover 51 communicates with the first strip opening 316. The lower housing cover 51 is connected to a filtering box 55. A filter plate 56 is installed in the filtering box 55. Specifically, when the air pump 67 is started, the pure gas in the side box 31 enters the upper housing cover 51 through the first strip opening 316 and penetrates through the filtering belt 33 into the lower housing cover 51. At this time, the pure gas and its flow direction cooperate with the brush for cleaning, so that the dust on the filtering belt 33 that is cleaned off can fall off and be discharged from the inside to the outside, thereby improving the cleaning effect, cleaning efficiency and cleaning quality of the filtering belt 33. Then, the gas enters the filter plate again for filtering, and then enters the upper housing cover 61 through the diversion box 57 and the first connecting pipe 58.

[0027] In this embodiment, a diversion box 57 is connected to the lower end of the filter box 55, and the diversion box 57 is communicated with the inner cavity of the second housing cover 61 located above through a first connecting pipe 58; so as to have a simple structure, stronger gas fluidity and higher efficiency.

[0028] In this embodiment, multiple layers of filter plates 56 are arranged at intervals; so as to improve the filtering effect on gas.

[0029] In this embodiment, the suspension rods 2 are evenly distributed along the outer periphery of the power transformation equipment 4; so as to fully blow cold air to the surface of the power transformation equipment 4.

[0030] In this embodiment, a ventilation window 8 is provided on the outer housing 1; so as to exchange the gas inside the outer housing 1 with the external gas.

[0031] During specific implementation, start the first motor 314 to drive the first conveyor belt 313 to drive the roller 312 to rotate, then the filter belt 33 can be driven to rotate. Start the second motor 323 to drive the second conveyor belt 324 to drive the rotating shaft rod 321 to rotate, then the first guide fan 322 can be driven to rotate. The first guide fan 322 extracts the gas in the cavity of the side box 31 and blows it to the surface of the power transformation equipment 4 through the air blowing pipe 32 for ventilation and heat dissipation treatment of the power transformation equipment 4. Start the air pump 67 to trigger the dehumidification mechanism 6 and the cleaning mechanism 5, adjust the power of the air pump 67 according to the humidity of the area where the power transformation equipment 4 is located, and start the humidity regulation mechanism 7 to adjust the humidity outside the power transformation equipment 4.

[0032] The above is only a preferred specific implementation manner of the invention, but the protection scope of the invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the invention, according to the technical solution and inventive concept of the invention, makes equivalent replacement or change, and should be covered by the protection scope of the invention.
