DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0035] See also Figures 1 to 6 The present invention relates to a dry-type transformer device with an alarm function, comprising a box body 1, a transformer body 2 is installed on the inner bottom wall of the box body 1, the inner wall of the box body 1 is rotatably connected to two vertical rods 3, and the two vertical rods 3 are sleeved with lifting blocks 4, the inner side of the left lifting block 4 is threadedly connected to the vertical rod 3, the top of the box body 1 is fixedly connected to a motor 1 5, the output shaft of the motor 1 5 passes through the box body 1 and is fixedly connected to the left vertical rod 3, a lifting frame 6 is fixedly connected between the two lifting blocks 4, the inner side of the lifting frame 6 is fixedly connected to two mounting frames 7, the two mounting frames 7 are installed on the opposite sides of the two conveyor belts 8, and the two conveyor belts 8 are installed on the opposite sides of the two sliders 9, and the two adjacent sliders 9 are rotatably connected with cleaning wheels 10, and the top two sliders 9 are embedded with motor 2 11, and the output shafts of the two motors 2 11 are fixedly connected to the two cleaning wheels 10 respectively, and the lifting frame 6 is a hollow design The inner wall of the lifting frame 6 is provided with an annular air outlet 12, and the top of the lifting frame 6 is connected with an air inlet pipe 13 and an air exhaust pipe 15. The air inlet pipe 13 and the air exhaust pipe 15 are both hoses. The top of the box body 1 is fixedly connected to the heat sink 14, the top of the air inlet pipe 13 passes through the box body 1 and is connected to the heat sink 14, the top of the air exhaust pipe 15 passes through the box body 1 and the heat sink 14 in turn and extends to the top of the heat sink 14, an air pump 16 is installed on the air inlet pipe 13 and the air exhaust pipe 15, the heat sink 14 and the left side of the box body 1 are embedded with a filter plate 17, and a refrigeration mechanism 18 is provided inside the heat sink 14; the refrigeration mechanism 18 includes two cooling fins 181, the bottoms of the two cooling fins 181 are embedded in the top of the heat sink 14, the bottoms of the two cooling fins 181 are located inside the heat sink 14, and the bottoms of the two cooling fins 181 are fixedly connected with evenly distributed heat-conducting rods 182.

[0036] In the present invention, the box 1 is used to place the transformer body 2. When the transformer body 2 is working, the user closes the valve on the exhaust pipe 15 and opens the air pump 16 on the right and the valve on the air inlet pipe 13. At this time, the outside air will pass through the filter plate 17 and be sucked into the lifting frame 6 from the air inlet pipe 13. The air will then be ejected from the multiple air outlet holes 12 into the box 1. The high-temperature air inside the box 1 is discharged from the filter plate 17 at the bottom, thereby achieving the effect of heat dissipation for the transformer body 2.

[0037] When the transformer body 2 is in overload operation for a long time, the user can turn on the cooling plate 181 to cool the air flowing in the heat dissipation box 14, thereby improving the heat dissipation effect of the transformer body 2. In terms of the heat dissipation effect, the user can turn on the motor 15 to control the height of the lifting frame 6. When the motor 15 is started, it will drive the left vertical rod 3 to rotate. The vertical rod 3 is threadedly connected to the lifting block 4. Therefore, after the motor 15 is turned on, it will drive the lifting frame 6 to move. After the lifting frame 6 moves, the position of the air outlet 12 will be changed, so that the air outlet 12 will spray toward the transformer body 2, which can improve the heat dissipation effect of the transformer body 2. By controlling the lifting frame 6 to rise and fall at a uniform speed, the transformer body 2 can be evenly cooled, thereby reducing the number of parts on the transformer body 2 that fail to achieve the heat dissipation effect, reducing the failure rate of the transformer body 2, and improving the practicality of the device.

[0038] After the transformer body 2 has been used for a period of time, when the surface of the transformer body 2 needs to be cleaned, the user can turn on the motor 2 11 to drive the cleaning wheel 10 to rotate. After the cleaning wheel 10 rotates, the dust on the surface of the transformer body 2 will be cleaned off. At the same time, turning on the two conveyor belts 8 can drive the two sliders 9 to move in a circular motion, thereby achieving the purpose of cleaning the surface of the transformer body 2. At the same time, the user closes the valves on the right air pump 16 and the air inlet pipe 13, and opens the air pump 16 and the valve on the exhaust pipe 15 on the left. At this time, the air pump 16 will draw the dust generated by cleaning into the exhaust pipe 15 and discharge it, thereby effectively avoiding dust pollution of the internal environment of the box 1, thereby improving the practicality of the device.

[0039] See also Figures 1 to 3 , wherein: a temperature sensor 19 and a controller 20 are installed on the inner wall of the box 1, the output end of the temperature sensor 19 is connected to the controller 20 signal, a buzzer 21 and an alarm 22 are fixedly connected to the front of the box 1, and the input ends of the buzzer 21 and the alarm 22 are both connected to the controller 20 signal.

[0040] In the present invention, when the transformer body 2 is in use, the temperature sensor 19 will detect the working environment temperature of the transformer body 2. If overheating occurs, the temperature sensor 19 will send a signal to the controller 20. After receiving the signal, the controller 20 will turn on the buzzer 21 and the alarm 22 to alarm, thereby allowing the transformer body 2 to have an alarm function, allowing the staff to stop the machine for inspection as soon as possible to avoid overheating and damage to the transformer body 2.

[0041] See also Figure 3 , wherein: a thermal imager 23 is installed on the inner wall of the box 1, and the output end of the thermal imager 23 is connected to the controller 20 for signal.

[0042] In the present invention, the setting of the thermal imager 23 can detect the temperature of various areas on the surface of the transformer body 2. If the temperature of a certain area of ​​the transformer body 2 is overheated, the controller 20 can control the lifting frame 6 to pause or slow down at the corresponding location, thereby improving the cooling effect of the overheated area, achieving the purpose of accurately cooling and dissipating the heat of the transformer body 2, and thus improving the practicality of the device.

[0043] See also Figure 3 and 5 , wherein: the top of the lifting frame 6 is fixedly connected with a fireproof cloth 24, the shape of the fireproof cloth 24 is annular, and the fireproof cloth 24 is a glass fiber cloth layer.

[0044] In the present invention, when encountering a fire, the lifting frame 6 will be in close contact with the inner bottom wall of the box body 1. At this time, the fireproof cloth 24 will cover the transformer body 2, thereby achieving a fireproof effect on the transformer body 2 and reducing the damage caused by the flame to the transformer body 2. If the transformer body 2 catches fire, it can also achieve a flame retardant effect, avoid the spread of flames, and reduce economic losses.

[0045] See also Figure 5 , wherein: an installation cavity 25 is provided inside the fireproof cloth 24, and the interior of the installation cavity 25 is filled with activated carbon.

[0046] In the present invention, the installation cavity 25 is filled with activated carbon, which can filter the smoke generated by the combustion of the transformer body 2, reduce the damage caused by harmful substances in the smoke to nearby personnel, facilitate the safe escape of workers, and facilitate fire extinguishing of the transformer body 2.

[0047] See also Figure 3 , wherein: a flame sensor 26 is installed on the inner wall of the box 1, and the output end of the flame sensor 26 is connected to the controller 20 signal.

[0048] In the present invention, the flame sensor 26 is provided to detect whether an open flame appears in the box 1. When an open flame appears, the flame sensor 26 sends a signal, and the controller 20 controls the motor 5 to drive the lifting frame 6 to descend, thereby performing fire prevention and flame isolation treatment on the transformer body 2, thereby improving the practicality of the device.

[0049] See also Figure 3 , wherein: a tank body 27 is embedded in the inner top wall of the box body 1, the bottom of the tank body 27 is connected to an exhaust pipe 28, and a solenoid valve 29 is installed on the exhaust pipe 28.

[0050] In the present invention, when a fire occurs, the solenoid valve 29 opens and the compressed carbon dioxide in the tank 27 is discharged, which can achieve the effect of extinguishing the fire. Moreover, if the transformer body 2 suddenly becomes hot, the carbon dioxide will also be discharged. The carbon dioxide can achieve the effect of assisting in cooling the transformer body 2, thereby reducing the damage to the transformer body 2 caused by the high temperature and improving the practicality of the device.
