[0020] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.
[0021] The structure of the present invention is described in detail below with reference to the accompanying drawings.
[0022] refer to Figures 1 to 7, an embodiment of the present invention provides a ventilation device and ventilation method for a transformer, comprising a box body 1, a mounting slot 2 is provided on one side of the box body 1, a plurality of air outlets 3 are provided on the upper side of the mounting slot 2, a mounting bracket 4 is fixedly connected to the lower side of the mounting slot 2, a transformer 5 is fixedly connected to the upper side of the mounting bracket 4, a closed door 6 is symmetrically hinged at the opening of the mounting slot 2, and a main ventilation mechanism is also included, the main ventilation mechanism includes an air storage chamber 7 opened inside the box body 1 and located below the mounting slot 2, a main suction component for sucking outside air into the air storage chamber 7 is provided below the air storage chamber 7, the mounting slot 2, two rotating grooves 8 are symmetrically provided on the lower side, a plurality of first air holes 9 communicating with the interior of the rotating grooves 8 are provided above the air storage chamber 7, and a side ventilation mechanism is provided. The side ventilation mechanism includes an air sleeve 10 rotatably connected to the rotating groove 8, a side air chamber 11 is provided in the air sleeve 10, and a plurality of second air holes 12 communicating with the interior of the side air chamber 11 are provided above the air sleeve 10. A rotation drive component for driving the two air sleeves 10 to rotate in opposite directions is provided on one side of the box body 1, and a side suction component for sucking the air inside the air storage chamber 7 into the inside of the side air chamber 11 is provided below the air sleeve 10.
[0023] When the heat dissipation demand is relatively small, the air sleeve 10 is in a horizontal state. At this time, only the side suction component needs to be driven, which will draw air from the air storage chamber 7 into the side air chamber 11, and blow it into the installation slot 2 through the second air hole 12 to ventilate and dissipate heat for the transformer 5. The air that has completed heat dissipation will be discharged from the air outlet 3.
[0024] When the heat dissipation demand is large and the transformer 5 needs to be cooled, the rotation drive component is started, which will drive the two air sleeves 10 to rotate toward the direction of the transformer 5 according to actual needs, so that the second air hole 12 is tilted to align with the transformer 5, and then the side suction component is started to absorb the air in the air storage chamber 7, and blow the air to the surface of the transformer 5 through the second air hole 12 for targeted ventilation and heat dissipation. At the same time, the main suction component is started, which will suck the outside air into the air storage chamber 7. The air sucked into the air storage chamber 7 will be blown into the rotating groove 8 through the first air hole 9, and enter the installation groove 2 under the guidance of the surface of the side of the air sleeve 10 away from the second air hole 12 to further ventilate and dissipate the heat of the transformer 5. The air that has completed heat dissipation will also be discharged from the air outlet 3.
[0025] Through this arrangement, the tiltable and rotatable air sleeve 10 can be used to carry out targeted ventilation and heat dissipation on the surface of the transformer 5, thereby effectively improving the ventilation and heat dissipation effect of the transformer 5, and preventing the transformer 5 from overheating and affecting its working efficiency. At the same time, by providing the first air hole 9 and the main suction component, the installation slot 2 can be further cooled when the heat dissipation demand is large, thereby further improving the heat dissipation effect of the transformer 5.
[0026] Furthermore, the rotation drive assembly includes a U-shaped frame 13 fixedly connected to one side of the box body 1, and a drive rod 14 is rotatably connected in the U-shaped frame 13, and the drive rod 14 is respectively provided with a positive thread 15 and a reverse thread 16, and two sliding racks 17 are symmetrically slidably connected in the U-shaped frame 13, and the two sliding racks 17 are respectively threadedly connected to the positive thread 15 and the reverse thread 16, and a driving motor 18 is fixedly connected to one side of the U-shaped frame 13, and the output end of the driving motor 18 extends into the U-shaped frame 13 and is fixedly connected to one end of the driving rod 14. The rotation drive assembly also includes a rotating rod 19 fixedly connected to both sides of the wind sleeve 10, and a rotating hole is provided on both sides of the rotating groove 8, and the rotating rod 19 is rotatably connected to the rotating hole. Two driving gears 20 are provided on the outside of the box body 1, and the two rotating rods 19 close to the sliding racks 17 extend to the outside of the box body 1 and are respectively fixedly connected to the two driving gears 20, and the two driving gears 20 are respectively meshed with the two sliding racks 17.
[0027] When it is necessary to drive the two air sleeves 10 to rotate toward the transformer 5, the drive motor 18 is started, which will drive the drive rod 14 to rotate, thereby relying on the positive thread 15 and the reverse thread 16 with opposite thread rotation directions to drive the two sliding racks 17 to move away from each other, and the two sliding racks 17 moving away from each other will drive the two driving gears 20 to rotate in opposite directions while sliding, thereby driving the two air sleeves 10 to rotate toward the transformer 5 from both sides through the rotating rod 19, so as to carry out targeted ventilation on the surface of the transformer 5, conversely, driving the drive rod 14 to reverse can reset the two air sleeves 10. Through this setting, the positive thread 15, the reverse thread 16 and the sliding rack 17 can be used to synchronously and stably drive the air sleeve 10, thereby effectively improving the driving effect of the air sleeve 10.
[0028] Furthermore, the main suction component includes an air inlet cavity 21 opened inside the box body 1 and located below the air storage cavity 7, a plurality of first mounting holes connected to the interior of the air storage cavity 7 are opened above the air inlet cavity 21, a first fan 22 is fixedly connected in the first mounting hole, an air inlet pipe 23 is fixedly connected on the side of the box body 1 away from the closed door 6, an air duct 24 is opened in the air inlet pipe 23, and the air duct 24 is connected to the interior of the air inlet cavity 21 below, and an air inlet 25 connected to the interior of the air duct 24 is opened on the side of the air inlet pipe 23 away from the closed door 6.
[0029] When it is necessary to draw outside air into the air storage chamber 7, the first fan 22 is started, which will draw outside air into the air inlet chamber 21 through the air inlet 25 and the air duct 24, and blow the air in the air inlet chamber 21 into the air storage chamber 7 through the first air hole 9 to ventilate and dissipate heat inside the installation slot 2. Through this setting, the first fan 22 can be used to blow outside air into the installation slot 2 through the first air hole 9, thereby further improving the heat dissipation effect of the transformer 5 and ensuring the efficient operation of the transformer 5. At the same time, by opening the air inlet 25 at a high place on the side of the air inlet pipe 23 away from the closed door 6, it can effectively prevent rainwater and water accumulated outside the box 1 from entering the air duct 24, thereby ensuring the safe use of the transformer 5.
[0030] Furthermore, the side suction assembly includes several second mounting holes opened above the air storage chamber 7, and an elastic hose 26 is fixedly connected above the second mounting hole. The end of the elastic hose 26 away from the second mounting hole is connected to the interior of the side air chamber 11, and a second fan 27 is fixedly connected in the second mounting hole.
[0031] When ventilation and heat dissipation are required through the second air hole 12, the second fan 27 is started, which draws air from the air storage chamber 7 and blows it into the side air chamber 11 through the elastic hose 26, thereby ventilating and dissipating the inside of the mounting slot 2 or the surface of the transformer 5 through the second air hole 12, ensuring that the transformer 5 can be cooled and work efficiently. At the same time, by providing the elastic hose 26, it can be ensured that the air sleeve 10 can stably draw air from the air storage chamber 7 when rotated to different inclination angles, thereby effectively improving the stability of the equipment.
[0032] Furthermore, a plurality of first receiving slots are provided on a side of the closed door 6 close to the transformer 5, a first windshield 28 is rotatably connected below the first receiving slot, a first V-shaped spring clip 29 is provided in the first receiving slot, and the two ends of the first V-shaped spring clip 29 are respectively fixedly connected to the first windshield 28 and the inner end surface of the first receiving slot. A plurality of second receiving slots are provided on the inner end surface of the mounting slot 2, a second windshield 30 is rotatably connected below the second receiving slot, and a second V-shaped spring clip 31 is provided in the second receiving slot. The two ends of the second V-shaped spring piece 31 are respectively fixedly connected to the second wind deflector 30 and the inner end surface of the second receiving groove. The closed door 6 is located above the first receiving groove and is fixedly connected to the sliding sleeve 32. The inner end surface of the installation groove 2 is located above the second receiving groove and is also fixedly connected to the sliding sleeve 32. A pull ring 33 is provided above the sliding sleeve 32, and a sliding rod 34 is fixedly connected below the pull ring 33. The sliding rod 34 is slidably inserted into the sliding sleeve 32, and the lower end of the sliding rod 34 is fixedly connected to a locking baffle 35.
[0033] When the first wind shield 28 and the second wind shield 30 are not in use, the first wind shield 28 and the second wind shield 30 are respectively stored in the first storage groove and the second storage groove. At this time, the locking baffle 35 falls naturally and blocks the side of the first wind shield 28 and the second wind shield 30 close to the transformer 5, so that the first wind shield 28 and the second wind shield 30 cannot pop out.
[0034] When the first wind shield 28 and the second wind shield 30 are needed, the sliding rod 34 and the locking baffle 35 are pulled upward by the pull ring 33. When the locking baffle 35 no longer blocks the first wind shield 28 and the second wind shield 30, the first wind shield 28 and the second wind shield 30 are respectively popped out by the first V-shaped spring piece 29 and the second V-shaped spring piece 31 to a predetermined angle. When the above-mentioned heat dissipation demand is small, the wind sleeve 10 is in a horizontal state, and the first wind shield 28 and the second wind shield 30 will guide the air blown out of the second wind hole 12 to blow it to the surface of the transformer 5 for targeted ventilation and heat dissipation of the transformer 5. When the above-mentioned heat dissipation demand is large, the wind sleeve 10 is tilted to align with the transformer 5, and the first wind shield 28 and the second wind shield 30 will guide the air blown out of the first wind hole 9, thereby further performing targeted ventilation and heat dissipation on the surface of the transformer 5.
[0035] In addition, several first wind shields 28 and second wind shields 30 are arranged above and below. When in use, the first wind shields 28 and second wind shields 30 of different heights can be popped out according to actual needs, so that targeted ventilation can be achieved on different surfaces and different heights of the transformer 5.
[0036] Through this arrangement, the first wind shield 28 and the second wind shield 30 can be used to further carry out targeted ventilation and heat dissipation on the surface of the transformer 5. At the same time, by popping out the first wind shield 28 and the second wind shield 30 at different heights, the targeted heat dissipation of the transformer 5 can be made more flexible and varied, thereby effectively improving the flexibility of use of the equipment and ensuring that the equipment has better ventilation and heat dissipation effects.
[0037] Furthermore, a plurality of side vents are provided on both sides of the box body 1 , a plurality of baffles 36 are rotatably connected in the side vents, and a rain shield 37 is fixedly connected to the top of the box body 1 .
[0038] By providing the side air vents, the air circulation inside the box 1 can be further improved, thereby further improving the ventilation and heat dissipation effect of the transformer 5. The provision of the rain shield 37 can ensure that rainwater does not flow into the installation groove 2 through the air outlet 3 and damage the transformer 5, thereby effectively improving the safety of the equipment.
[0039] A transformer ventilation method comprises the following steps: Step 1: Determine the heat dissipation requirement based on the operating status, load and temperature data of the transformer 5; Step 2: Determine whether to use the first windshield 28 and the second windshield 30, and the positions of the first windshield 28 and the second windshield 30 to be used; Step 3: After determining to use the wind deflector, pull up the locking baffle 35 as needed to pop out the first wind deflector 28 and the second wind deflector 30 to guide the airflow during subsequent ventilation; Step 4: After determining that the heat dissipation demand is small, the second fan 27 is started, and air is blown out from the second air hole 12 of the horizontal air sleeve 10 through the air storage chamber 7, the elastic hose 26, and the side air chamber 11 to ventilate and dissipate heat inside the installation slot 2, and the hot air is discharged from the air outlet 3; Step 5: After determining that the heat dissipation demand is large, start the drive motor 18, and drive the air sleeve 10 to rotate through the drive rod 14, the sliding rack 17 and the drive gear 20, so that the second air hole 12 is aligned with the transformer 5, and the transformer 5 is subjected to targeted heat dissipation through the second fan 27. At the same time, start the first fan 22 to allow the outside air to enter the air storage chamber 7 through the air inlet cavity 21, and then enter the installation slot 2 through the first air hole 9 to assist in heat dissipation.
[0040] Working principle of the present invention: When the heat dissipation demand is relatively small, the air sleeve 10 is in a horizontal state. At this time, only the side suction component needs to be driven, which will draw air from the air storage chamber 7 into the side air chamber 11, and blow it into the installation slot 2 through the second air hole 12 to ventilate and dissipate heat for the transformer 5. The air that has completed heat dissipation will be discharged from the air outlet 3.
[0041] When the heat dissipation demand is large and the transformer 5 needs to be cooled, the rotation drive component is started, which will drive the two air sleeves 10 to rotate toward the direction of the transformer 5 according to actual needs, so that the second air hole 12 is tilted to align with the transformer 5, and then the side suction component is started to absorb the air in the air storage chamber 7, and blow the air to the surface of the transformer 5 through the second air hole 12 for targeted ventilation and heat dissipation. At the same time, the main suction component is started, which will suck the outside air into the air storage chamber 7. The air sucked into the air storage chamber 7 will be blown into the rotating groove 8 through the first air hole 9, and enter the installation groove 2 under the guidance of the surface of the side of the air sleeve 10 away from the second air hole 12 to further ventilate and dissipate the heat of the transformer 5. The air that has completed heat dissipation will also be discharged from the air outlet 3.
