Description

[0003] Existing box-type substations usually have power equipment such as transformers installed inside. During the operation of the power equipment, it will generate heat, which will continue to accumulate inside the substation, causing the temperature inside the substation to rise rapidly in a short period of time.

[0014] The present invention has the following beneficial effects: 1. By setting up the air cooling mechanism, when the weather is clear, the driving motor rotates, driving the fan blades to rotate, so that the air inside the substation body can circulate quickly, taking away the hot air inside, thereby reducing the temperature inside the substation body and avoiding overheating and damage to the internal transformer and other power equipment; 2. By setting up a dehumidification mechanism, the rotation of the rotating shaft will synchronously drive the rotation of the first gear ring, and then drive the rotation of the first gear, and drive the rotation of the first reciprocating screw, so that the slider slides back and forth on the inner wall of the slide slot, drives the frame to move back and forth up and down, and then drives the water-absorbing sponge to move back and forth up and down to wipe the side wall of the transformer box. Due to the change in temperature difference between morning and evening, the temperature drops at night, and the water vapor in the air may condense into water droplets attached to the outside of the transformer box, and the water-absorbing sponge can absorb the water droplets to prevent the water droplets from penetrating into the inside of the transformer box, causing the transformer to be short-circuited and damaged; 3. By setting a rainproof mechanism, if it rains, the rainproof cover can play a certain role in preventing rain from directly entering the substation body through the air inlet, causing short circuit damage to the internal power equipment. Due to the wind direction, some rain may drift into the air inlet obliquely, and some rain will fall into the rain collecting trough for collection. As the rain in the rain collecting trough gradually increases, the weight of the rainproof cover will gradually increase, and then the rainproof cover can overcome the elastic force of the spring to drive the vertical rod to slide downward, and then drive the sealing plug to move downward until the sealing plug completely enters the air inlet to block the air inlet, thereby preventing some rain from obliquely entering the air inlet. In the process of the vertical rod sliding downward, the air in the vertical groove will be squeezed into the horizontal groove through the connecting pipe, thereby pushing the two sealing plates to slide close to each other until the two sealing plates are against each other, sealing the exhaust port, which can prevent rain from entering the substation body through the exhaust port, further playing a waterproof role. 4. By setting a water cooling mechanism, in rainy weather, the rotating shaft will be driven by the rainproof cover to slide downward, thereby driving the first gear ring to move downward, and driving the second gear ring to move downward. At this time, the first gear ring is separated from the first gear, and the second gear ring is meshed with the second gear. The rotation of the second gear ring will drive the second gear to rotate, and then drive the second reciprocating screw to rotate, driving the rectangular block to slide back and forth on the inner wall of the pump water tank. The rectangular block will drive the sliding plug to slide back and forth through the cross bar. At this time, rainwater in the rain collecting trough will be pumped into the pump water tank through the one-way water inlet pipe, and then the rainwater in the pump water tank will be squeezed into the water inlet cavity through the one-way water outlet pipe. The heat conducting plate can transfer the heat in the substation body, thereby generating heat exchange with the rainwater in the water inlet cavity, thereby cooling the inside of the substation body, and then the rainwater will be discharged through the drain pipe. At this time, it will switch to water cooling, so that the cooling of the inside of the substation body can be maintained while preventing rain, and the rainwater can be utilized at the same time to improve the utilization rate of resources; 5. This device automatically switches the cooling mode according to the weather, which is realized by mechanical structure linkage. There is no need to set up complex control programs, the structure is simple, and the cost is low; 6. By setting the first filter, the second filter and the bristles, when the external air enters the substation body through the air inlet, the dust in the air will be intercepted by the first filter, thereby preventing the dust from entering the substation body and causing damage to the power equipment. The rotation of the shaft will drive the sealing plug to rotate, and then drive the multiple bristles to rotate, brushing off the dust on the first filter, preventing the dust from clogging the first filter and affecting the air intake. The second filter can also block external dust from entering the substation body through the exhaust port. When the air is discharged through the exhaust port, it will also flow through the second filter, blowing off the dust on the second filter and cleaning the second filter.

[0021] The dehumidification mechanism also includes a first reciprocating screw 16 rotatably connected to the inner wall of the slide groove 11, the side wall of the first reciprocating screw 16 is threadedly connected to the slider 12, the upper end of the first reciprocating screw 16 passes through the upper end of the mounting frame 2 and is fixedly connected to the first gear 17, the side wall of the rotating shaft 9 is fixedly connected to the first ring gear 18 through a fixed shaft, and the first ring gear 18 is meshingly connected to the first gear 17.

[0022] Furthermore, the rotation of the rotating shaft 9 will synchronously drive the first gear ring 18 to rotate, and then drive the first gear 17 to rotate, and drive the first reciprocating screw 16 to rotate, so that the slider 12 slides back and forth on the inner wall of the slide groove 11, driving the frame 13 to move back and forth up and down, and then driving the water-absorbing sponge 14 to move back and forth up and down to wipe the side walls of the transformer case 3. Due to the change in temperature difference between morning and evening, the temperature drops at night, and the water vapor in the air may condense into water droplets attached to the outside of the transformer case 3, and the water-absorbing sponge 14 can absorb the water droplets to prevent the water droplets from penetrating into the inside of the transformer case 3, causing the transformer to be short-circuited and damaged.

[0023] A rainproof mechanism is installed on the substation body 1, and the rainproof mechanism includes a plurality of vertical grooves 19 opened at the upper end of the substation body 1, a plurality of vertical rods 20 are sealingly and slidably connected to the inner walls of the plurality of vertical grooves 19, a rainproof cover 21 is fixedly connected to the upper ends of the plurality of vertical rods 20, a spring 22 is fixedly connected to the bottom of the vertical groove 19, the upper end of the spring 22 is fixedly connected to the lower end of the vertical rod 20, the upper end of the rotating shaft 9 is rotatably connected to the lower end of the rainproof cover 21, and a sealing plug 23 cooperating with the air inlet 4 is fixedly connected to the side wall of the rotating shaft 9.

[0024] The rainproof mechanism also includes two transverse grooves 24 symmetrically opened on the inner wall of the exhaust port 5. The inner walls of the two transverse grooves 24 are sealed and slidably connected with sealing plates 25. The vertical groove 19 is connected to the transverse groove 24 through a connecting pipe 26. A rain collecting trough 30 is opened at the upper end of the rainproof cover 21.

[0025] It should be noted that when the rainwater in the rain collecting trough 30 reaches one third of the internal volume of the rain collecting trough 30 , the vertical rod 20 slides to the lowest position of the vertical groove 19 .

[0026] Furthermore, if it rains, the rain cover 21 can play a certain role in preventing rain from directly entering the substation body 1 through the air inlet 4, causing short circuit damage to the internal power equipment. Due to the wind direction, some rainwater may drift into the air inlet 4 obliquely, and some rainwater will fall into the rain collecting trough 30 for collection. As the rainwater in the rain collecting trough 30 gradually increases, the weight of the rain cover 21 will gradually increase, and then the rain cover 21 can overcome the elastic force of the spring 22 to drive the vertical rod 20 to slide downward, The sealing plug 23 is driven to move downward until the sealing plug 23 completely enters the air inlet 4 to block the air inlet 4, thereby preventing some rainwater from obliquely entering the air inlet 4. In the process of the vertical rod 20 sliding downward, the air in the vertical groove 19 will be squeezed into the horizontal groove 24 through the connecting pipe 26, thereby pushing the two sealing plates 25 to slide close to each other until the two sealing plates 25 abut against each other, thereby sealing the exhaust port 5, thereby preventing rainwater from entering the interior of the substation body 1 through the exhaust port 5, thereby further playing a waterproof role.

[0027] The water cooling mechanism includes a water inlet cavity 27 opened in the side wall of the transformer substation body 1, two pump water tanks 28 are symmetrically fixedly connected to the upper end of the mounting frame 2 through a fixed axis, a sliding plug 29 is sealingly and slidably connected to the inner wall of the pump water tank 28, the pump water tank 28 is connected to the rainwater collecting trough 30 through a one-way water inlet pipe 31, the one-way water inlet pipe 31 is made of a hose, and the one-way water inlet pipe 31 only allows rainwater in the rainwater collecting trough 30 to enter the pump water tank 28, the pump water tank 28 is connected to the water inlet cavity 27 through a one-way water outlet pipe 32, the one-way water outlet pipe 32 only allows rainwater in the pump water tank 28 to enter the water inlet cavity 27, two drain pipes 33 are symmetrically and fixedly connected to the bottom of the water inlet cavity 27, the other ends of the two drain pipes 33 are extended to the outside of the transformer substation body 1, a heat conducting plate 42 is sealed and embedded in the inner wall of the transformer substation body 1, and one end of the heat conducting plate 42 extends to the water inlet cavity 27.

[0028] The water cooling mechanism also includes a rectangular block 34 slidably connected to the inner wall of the pump water box 28. The rectangular block 34 is symmetrically fixedly connected to the side wall of the sliding plug 29 with two cross bars 35. The other ends of the two cross bars 35 are fixedly connected to the side wall of the sliding plug 29. The inner wall of the pump water box 28 is rotatably connected to a second reciprocating screw 36. The side wall of the second reciprocating screw 36 is threadedly connected to the rectangular block 34. One end of the second reciprocating screw 36 passes through the side wall of the pump water box 28 and is fixedly connected to a second gear 37. The lower end of the first ring gear 18 is fixedly connected to a second ring gear 38 that cooperates with the second gear 37.

[0029] Furthermore, when the air inlet 4 and the air outlet 5 are sealed, air cooling cannot be performed. At this time, the rotating shaft 9 will be driven by the rain cover 21 to slide downward, thereby driving the first gear ring 18 to move downward, and driving the second gear ring 38 to move downward. At this time, the first gear ring 18 is separated from the first gear 17, and the second gear ring 38 will mesh with the second gear 37. The rotation of the second gear ring 38 will drive the second gear 37 to rotate, and then drive the second reciprocating screw 36 to rotate, driving the rectangular block 34 to slide back and forth on the inner wall of the pump water tank 28. The rectangular block 34 will drive the sliding plug 29 to slide back and forth in a sealed manner through the cross bar 35. At this time, the rainwater in the rainwater collecting trough 30 will be pumped into the pump water box 28 through the one-way water inlet pipe 31, and then the rainwater in the pump water box 28 will be squeezed into the water inlet chamber 27 through the one-way water outlet pipe 32. The heat conducting plate 42 can transfer the heat in the substation body 1, thereby generating heat exchange with the rainwater in the water inlet chamber 27, and then cooling the inside of the substation body 1. Then the rainwater will be discharged through the drain pipe 33. At this time, it will switch to water cooling, so that while preventing rain, it can also maintain the cooling of the inside of the substation body 1, and at the same time, the rainwater can be utilized to improve the utilization rate of resources.

The rotation of the rotating shaft 9 will drive the sealing plug 23 to rotate, and then drive the multiple bristles 41 to rotate, brushing off the dust on the first filter 39 to prevent dust from clogging the first filter 39 and affecting the air intake. The second filter 40 can also block external dust from entering the substation body 1 through the exhaust port 5. When the air is discharged through the exhaust port 5, it will also flow through the second filter 40, blowing off the dust on the second filter 40 and cleaning the second filter 40.

[0032] In the present invention, when the weather is clear, the driving motor 6 rotates, driving the spline sleeve 7 to rotate, and then driving the spline shaft 8 to rotate, driving the rotating shaft 9 to rotate, and driving the multiple fan blades 10 to rotate, generating a suction force, and the external air will enter the substation body 1 through the air inlet 4, and then the air will flow from top to bottom, and finally the air will be discharged through the exhaust port 5, so that the air inside the substation body 1 will circulate quickly, taking away the hot air inside it, thereby reducing the temperature inside the substation body 1 and avoiding overheating and damage to internal power equipment such as transformers.

[0033] When external air enters the substation body 1 through the air inlet 4, dust in the air will be intercepted by the first filter 39, thereby preventing dust from entering the substation body 1 and causing damage to the power equipment. The rotation of the rotating shaft 9 will drive the sealing plug 23 to rotate, and then drive the multiple bristles 41 to rotate, brushing off the dust on the first filter 39 to prevent dust from clogging the first filter 39 and affecting the air intake. The second filter 40 can also block external dust from entering the substation body 1 through the exhaust port 5. When the air is discharged through the exhaust port 5, it will also flow through the second filter 40, blow off the dust on the second filter 40, and clean the second filter 40.

[0034] In addition, the rotation of the rotating shaft 9 will synchronously drive the first gear ring 18 to rotate, and then drive the first gear 17 to rotate, and drive the first reciprocating screw 16 to rotate, so that the slider 12 slides back and forth on the inner wall of the slide groove 11, driving the frame 13 to move back and forth up and down, and then driving the absorbent sponge 14 to move back and forth up and down to wipe the side wall of the transformer box 3. Due to the change in temperature difference between morning and evening, the temperature drops at night, and the water vapor in the air may condense into water droplets attached to the outside of the transformer box 3, and the absorbent sponge 14 can absorb the water droplets to prevent the water droplets from penetrating into the inside of the transformer box 3, causing the transformer to be short-circuited and damaged.

[0035] If it rains, the rain cover 21 can play a certain role in preventing rain from directly entering the substation body 1 through the air inlet 4, causing short circuit damage to the internal power equipment. Due to the wind direction, some rain may drift into the air inlet 4 obliquely, and some rain will fall into the rain collecting trough 30 for collection. As the rain in the rain collecting trough 30 gradually increases, the weight of the rain cover 21 will gradually increase, and then the rain cover 21 can overcome the elastic force of the spring 22 to drive the vertical rod 20 to slide downward, thereby driving The sealing plug 23 moves downward until the sealing plug 23 completely enters the air inlet 4 to block the air inlet 4, thereby preventing some rainwater from obliquely entering the air inlet 4, and during the downward sliding of the vertical rod 20, the air in the vertical groove 19 will be squeezed into the horizontal groove 24 through the connecting pipe 26, thereby pushing the two sealing plates 25 to slide closer to each other until the two sealing plates 25 abut against each other, sealing the exhaust port 5, thereby preventing rainwater from entering the interior of the substation body 1 through the exhaust port 5, and further playing a waterproof role.

[0036] When the air inlet 4 and the air outlet 5 are sealed, air cooling cannot be performed. At this time, the rotating shaft 9 will be driven by the rain cover 21 to slide downward, thereby driving the first gear ring 18 to move downward, and driving the second gear ring 38 to move downward. At this time, the first gear ring 18 is separated from the first gear 17, and the second gear ring 38 will mesh with the second gear 37. The rotation of the second gear ring 38 will drive the second gear 37 to rotate, and then drive the second reciprocating screw 36 to rotate, driving the rectangular block 34 to slide back and forth on the inner wall of the pump water tank 28. The rectangular block 34 will drive the sliding plug 29 to slide back and forth through the cross bar 35. The rainwater in the rainwater collecting trough 30 will be pumped into the pump water box 28 through the one-way water inlet pipe 31, and then the rainwater in the pump water box 28 will be squeezed into the water inlet chamber 27 through the one-way water outlet pipe 32. The heat conducting plate 42 can transfer the heat in the substation body 1, thereby generating heat exchange with the rainwater in the water inlet chamber 27, and then cooling the inside of the substation body 1. Then the rainwater will be discharged through the drain pipe 33, and it will switch to water cooling at this time, so that it can keep the temperature inside the substation body 1 while preventing rain, and at the same time make use of the rainwater to improve the utilization rate of resources.
