[0001] The invention belongs to the technical field of air insulation cabinets, in particular to a box-type fixed air insulation cabinet. Background Art

[0002] Box-type fixed air-insulated cabinet, usually referred to as air-insulated switchgear, is a switchgear that uses air as the insulating medium. The working principle is that the external line first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs, such as instruments, automatic control, motor magnetic switches, various AC contactors, etc.

[0003] The existing box-type fixed air-insulated cabinet is usually kept sealed inside so that the air can insulate the electronic equipment inside. However, when the internal equipment is running, a large amount of heat will be generated, which needs to be dissipated. However, due to the seal, it is impossible to design a heat dissipation port for ventilation and heat dissipation. The existing method is to dissipate heat on the surface of the cabinet by setting a heat dissipation mechanism on the surface.

[0022] The elastic force of the first spring 602 can push the piston rod 601 to move downward as a whole. Then, when hot air squeezes the bottom of the piston rod 601 and pushes it upward, the first spring 602 will be compressed. Then, the hot air is blocked by the baffle 604 and guided to the top of the driving rotating blade 603 to push it, thereby driving the driving rotating blade 603 to rotate as a whole.

[0023] like Figure 4 and Figure 6 As shown, the cooling mechanism 5 includes a cooling heat exchange tube 501, a disc water tank 502 and a rotating wheel 503; The cooling and heat exchange tube 501 is arranged inside the air insulation cabinet body 1, the disc water tank 502 is arranged at the rear end of the cooling box 4, and is fixedly connected to the rear end of the cooling and heat exchange tube 501, the rotating wheel 503 is movably sleeved on the inner cavity of the disc water tank 502, and the rear end of the rotating wheel 503 is transmission-connected to the rear end of the driving rotating blade 603 through the transmission belt 8.

[0024] The above scheme is adopted: by providing a rotating wheel 503, when the driving rotating blade 603 drives the transmission belt 8 to move, the rotating wheel 503 can be driven to rotate synchronously. At this time, the rotation of the rotating wheel 503 can drive the water inside the disc water tank 502 to flow back and forth between the disc water tank 502 and the cooling and heat exchange tube 501, so that the transmission belt 8 can keep driving the rotating blade 603 to rotate.

[0025] like Figure 3 and Figure 5 As shown, the surface of the ventilation pipe 3 is provided with a locking assembly 7 located on the back of the driving rotating blade 603, and the locking assembly 7 includes a locking gear 701, a locking tooth block 702, a movable frame 703 and a second spring 704; The locking gear 701 is fixedly sleeved on the rear end of the driving rotating blade 603 and is located on the back side of the ventilation pipe 3. The locking tooth block 702 is movably installed on the surface of the ventilation pipe 3 and is located on one side of the locking gear 701.

The surface of the locking gear 701 is meshed with the side of the locking tooth block 702 that is in contact with it.

[0026] The above scheme is adopted: by providing a movable frame 703, the locking tooth block 702 can be pushed to move toward the locking gear 701 through the elastic force of the movable frame 703 until it engages and clamps with the surface of the locking gear 701, so that the locking gear 701 and the driving rotating blade 603 can be clamped and fixed as a whole.

[0027] like Figure 3 As shown, the top surface of one side of the movable frame 703 is in contact with the bottom surface of one side of the locking tooth block 702, and both are in the shape of an inclined surface.

[0028] The above scheme is adopted: by providing a movable frame 703, when the movable frame 703 is pushed upward as a whole, the top surface of one side of the movable frame 703 will slide along the bottom surface of one side of the locking tooth block 702, driving the locking tooth block 702 to move to one side away from the surface of the locking gear 701, until the teeth on one side of the locking tooth block 702 are separated from the surface of the locking gear 701, and the meshing and clamping effect of the locking gear 701 can be successfully released.

[0029] like Figure 2 and Figure 6 As shown, the rear end of the rotating wheel 503 is provided with a linkage assembly 9 located on the back of the transmission belt 8, and the linkage assembly 9 includes a first connecting block 901, a linkage plate 902, a second connecting block 903 and a bevel gear rod 904; The first connecting block 901 is fixedly sleeved on the rear end of the rotating wheel 503, the bevel gear rod 904 is movably sleeved on the other side of the cooling box 4, the second connecting block 903 is fixedly sleeved on the rear end of the bevel gear rod 904, and the linkage plate 902 is movably sleeved on the rear ends of the first connecting block 901 and the second connecting block 903.

[0030] By adopting the above solution, the linkage plate 902 is provided, and when the rotating wheel 503 rotates, the first connecting block 901 can be driven to rotate, so that the linkage plate 902 drives the second connecting block 903 and the bevel gear rod 904 to rotate as a whole.

[0031] like Figure 6 As shown, the other side of the cooling box 4 is movably sleeved with a second driving assembly 10, and the second driving assembly 10 includes a driving gear rod 101, a driven gear 102 and a driven bevel gear 103; The driving gear rod 101 is movably sleeved in the middle of the other side of the cooling box 4, the driven gear 102 is movably sleeved in the interior of the cooling box 4 and is located on one side of the bottom of the driving gear rod 101, and the driven bevel gear 103 is fixedly sleeved on the top of the driving gear rod 101; The bottom end surface of the driving gear rod 101 meshes with the surface of the driven gear 102 .

[0032] By adopting the above solution, the driving gear rod 101 is provided. When the driving gear rod 101 rotates, the teeth on the bottom surface of the driving gear rod 101 drive the teeth on the surface of the driven gear 102, thereby driving the driven gear 102 to rotate as a whole.

[0033] like Figure 6 As shown, the surface of the driven bevel gear 103 is meshed with the front end surface of the bevel gear rod 904 .

[0034] By adopting the above solution, the driven bevel gear 103 is provided. When the bevel gear rod 904 is driven to rotate, the teeth on the rear end surface drive the teeth on the surface of the driven bevel gear 103, so that the driven bevel gear 103 and the driving gear rod 101 rotate synchronously as a whole.

[0035] like Figure 4 and Figure 6 As shown, a conveying assembly 11 is arranged between the bottom end of the cooling box 4 and the top end of the air insulation cabinet body 1, and the conveying assembly 11 includes a conveying pipeline 1101, a conveying fan blade 1102, a one-way valve column 1103 and a power spring 1104; The bottom end of the cooling box 4 is fixedly connected to the top of the air insulation cabinet body 1 through the conveying pipe 1101, the conveying fan blade 1102 is movably sleeved on the top inner wall of the conveying pipe 1101, the one-way valve column 1103 is movably installed on the inner wall of the conveying pipe 1101, and is located below the conveying fan blade 1102, and the bottom end of the one-way valve column 1103 is elastically connected to the inner wall of the conveying pipe 1101 through a power spring 1104.

[0036] The above scheme is adopted: by providing a power spring 1104, when gas enters the delivery pipe 1101, it can squeeze and push the one-way valve column 1103 as a whole downward, and compress the power spring 1104. When the top of the one-way valve column 1103 loses the push, the elastic force of the power spring 1104 can be released to push the one-way valve column 1103 as a whole to reset upward, and at the same time, it can prevent the gas inside the air insulation cabinet body 1 from entering the cooling box 4 through the delivery pipe 1101.

[0037] like Figure 7 As shown, the conveying blade 1102 is meshed with the surface of the driven gear 102 .

[0038] The above scheme is adopted: by providing a conveying blade 1102, when the driven gear 102 rotates, the teeth on the surface of the driven gear 102 can drive the teeth on the surface of the conveying blade 1102, thereby driving the conveying blade 1102 to rotate as a whole, and finally a negative pressure area is generated on the top of the conveying blade 1102, which can guide the gas in the cooling box 4 to the inside of the conveying pipe 1101 and push the one-way valve column 1103 to open, and reflux to the inside of the air insulation cabinet body 1 for replenishment.

[0039] The working principle and use process of the present invention: First, when the equipment inside the air-insulated cabinet body 1 is running and the air heats up, expands and rises, the hot air will accumulate and push the bottom of the piston rod 601, so that the piston rod 601 is completely pushed upward. At this time, the piston rod 601 will push the movable frame 703 to move upward as a whole, so that the inclined surface on one side of the movable frame 703 squeezes and pushes the locking tooth block 702 as a whole to move to one side, so that the other side is separated from the surface of the locking gear 701 to release the meshing and clamping effect, thereby releasing the locking and fixing effect on the driving rotating blade 603.

[0040] Then, the hot air pushes the top of the driving rotating blade 603, and the driving rotating blade 603 can be driven to rotate as a whole, so as to drive the transmission belt 8 to drive the rotating wheel 503 to rotate, so that the water inside the disc water tank 502 flows, and then the water flow will drive the transmission belt 8 and the driving rotating blade 603 to rotate continuously for gas-assisted transportation to the inside of the cooling box 4, and the water flow flows back and forth in the cooling heat exchange tube 501 and the disc water tank 502 to rotate, so that the water absorbing heat in the cooling heat exchange tube 501 can be subjected to hot and cold interactive cooling treatment, and finally the cooling heat exchange tube 501 can smoothly cool the hot air inside the cooling box 4.

[0041] When the rotating wheel 503 rotates, it will drive the first connecting block 901 to rotate through the linkage plate 902, driving the second connecting block 903 and the bevel gear rod 904 to rotate synchronously. At this time, due to the meshing relationship between the bevel gear rod 904 and the surface of the driven bevel gear 103, the driven bevel gear 103 and the driving gear rod 101 can be driven to rotate as a whole. Then, due to the meshing relationship between the bottom surface of the driving gear rod 101 and one side of the surface of the driven gear 102, the driven gear 102 can be driven to rotate, and then the conveying fan blade 1102 meshing with the other side of the surface of the driven gear 102 can be driven to rotate, and finally the conveying fan blade 1102 rotates to drive the cooled gas inside the cooling box 4 into the conveying pipe 1101, pushing the one-way valve column 1103 downward as a whole. At this time, the gas can flow back to the inside of the air insulation cabinet body 1 through the gap generated by the one-way valve column 1103 downward, thereby realizing the cooling and heat dissipation of the hot air.

[0042] Supplementary explanation: The entire air-insulated cabinet body 1 is installed and fixed in the distribution room, and the indoor environment maintains a certain degree of cleanliness, which can prevent dust particles from adhering to the gaps between the locking gear 701 and the locking tooth block 702, the bevel gear rod 904 and the driven bevel gear 103, and the driving gear rod 101 and the driven gear 102, causing blockage.
