[0024] The rotating device 2 includes a connecting ring 21, a hollow fixed frame 22 and a hollow moving frame 23; the connecting ring 21 is rotatably connected to the outside of the cylinder 11, and the connecting ring 21 is fixedly connected with a hollow fixed frame 22 connected with a through hole 211 on the connecting ring 21, and the through hole 211 is also connected with a corresponding through hole 12; the connecting ring 21 is also provided with a hollow moving frame 23 that slidably cooperates with the through hole 211; the outer circumferential surface of the connecting ring 21 is also provided with a tooth groove; the wall 4 is fixedly connected with a motor Ⅰ6, and the output shaft of the motor Ⅰ6 is fixedly connected with a gear 7 that meshes with the tooth groove; the hollow fixed frame 22 is provided with a vent hole Ⅰ224; the hollow moving frame 23 is provided with a vent hole Ⅱ233;

[0025] The collecting device 3 comprises a movable block 31; the interior of the cylinder 11 is fixedly connected to a motor II 15 through a bracket 14; a screw 16 is fixedly connected to the output shaft of the motor II 15; a threaded hole 32 is provided on the movable block 31 to which the screw 16 is threadedly connected; an electric telescopic rod I 33 is fixedly connected to the lower end of the movable block 31; the electric telescopic rod I 33 passes through a slide groove 13 on the outer circumferential surface of the cylinder 11 and is parallel to the central axis of the cylinder 11; a connecting seat 36 is fixedly connected to the lower end of the connecting seat 36, and a temperature sensor 37 is fixedly connected to the lower end of the connecting seat 36;

[0026] The temperature sensor 37, motor I6, motor II15 and electric telescopic rod I33 are all electrically connected to the controller. Under the control of the controller, motor I6 drives the rotating device 2 to rotate, so that the fixed cylinder 22 moves to the bottom of the cylinder 11, and then the vent holes I224 and III228 are closer to the equipment.

[0027] The hollow fixed frame 22 includes a body I 221, an electric telescopic rod II 222 is fixedly connected to the body I 221, and the hollow moving frame 23 includes a body II 231; the free end of the electric telescopic rod II 222 is fixedly connected to the body II 231 and can drive the body II 231 to move; the electric telescopic rod II 222 is electrically connected to the controller. The position of the slide 2 is controlled by the electric telescopic rod II 222, thereby achieving the purpose of blocking the vent hole II 233 on the slide 2.

[0028] The hollow fixed frame 22 and the hollow movable frame 23 are both designed to be U-shaped.

[0029] The outer side of the body I 221 is provided with a vent hole III 228, and a rubber plug 227 is provided in the vent hole III 228. A connecting rod 225 is fixedly connected to the side of the rubber plug 227, and the other end of the connecting rod 225 passes through the vent hole I 224 and is fixedly connected to the transmission plate 223; the connecting rod 225 is also sleeved with a spring 226 located between the rubber plug 227 and the inner wall of the body I 221. After the fixed cylinder 22 rotates, the vent hole III 228 is directly located above the high temperature area, which can effectively reduce the temperature of the high temperature area.

[0030] The cross-sectional area of ​​the vent hole III 228 is larger than that of the vent hole I 224. The air intake volume per unit time of the vent hole III 228 is larger than that of the vent hole I 224. Since the vent hole III 228 is located above the high temperature area, the heat dissipation efficiency is effectively improved.

[0031] A fixing ring 34 is fixedly connected to the side of the free end of the electric telescopic rod I 33, and a fixing frame 35 is fixedly connected to the outer side of the fixing ring 34; a circular ring 38 is fixedly connected to the lower end of the fixing frame 35. The circular ring 38 drives the transmission plate 223 to move, so that the vent hole III 228 is connected to the outside.

[0032] The two end sides of the body II 231 are provided with slideways 232 that slide with the screw 16. The side of the body II 231 facing the cylinder 11 is fixedly connected with a pad 234, and the pad 234 is provided with a hole 235 that is connected to the corresponding vent hole II 233; the two ends of the body II 231 can slide into the interior of the body I 221.

[0033] The side of the pad 234 facing the cylinder 11 is set as an arc surface. A temperature control method for a power distribution station, the control method comprising the following steps:

[0034] Step 1: Turn on the power supply, and the exhaust fan 5 and the motor II 15 start working;

[0035] Step 2: When it is detected that the local temperature is too high and reaches a preset high threshold, the controller controls the motor II 15 to stop working, and at the same time the motor I 6 drives the rotating device 2 to rotate, so that the hollow fixed frame 22 is located below the cylinder 11, the electric telescopic rod I 33 is stretched, and the electric telescopic rod II 222 is contracted, so that the hollow movable frame 23 slides downward, and at the same time drives the ring 38 to move downward, and then drives the transmission plate 223 under the ring 38 to move to cover the vent hole I 224 at the corresponding position, so that the corresponding vent hole III 228 is exposed, thereby accelerating local heat dissipation;

[0036] Step 3: When the local temperature drops to a preset low threshold, the rotating device 2 and the electric telescopic rod Ⅰ33 are reset, and the control motor Ⅱ15 continues to work.

[0037] The working principle of the present invention is: when using the device, the power is turned on, the exhaust fan 5 and the motor II 15 work, the motor II 15 drives the screw 16 to rotate, and then drives the movable block 31 to move back and forth along the setting direction of the screw 16, so that the range that the temperature sensor 37 can monitor is increased; the exhaust fan 5 draws the heat inside the distribution station from the vent I 224, the vent II 233, the hole 235, and the slide groove 13 into the cylinder 11, the fixed cylinder 22 and the slide cylinder 23, and then discharges it.

[0038] Specifically, when the temperature sensor 37 moves to a certain position and the temperature at the position is higher than a predetermined value, an alarm is sounded, and the controller controls the motor II 15 to stop rotating, so that the temperature sensor 37 stays at the position. At the same time, the controller controls the motor I6 to start, and the motor I6 drives the gear 7 to rotate. The gear 7 drives one of the connecting rings 21 to rotate through the tooth groove, and then drives the fixed cylinder 22 and the sliding cylinder 23 to rotate, so that the fixed cylinder 22 is located below the cylinder body 11; then the controller controls the electric telescopic rod II 222 to retract, thereby driving the sliding cylinder 23 to rotate. The cylinder 23 moves toward the fixed cylinder 22, and finally the slideway 232 completely enters the cylinder body 11, the cushion block 234 is close to the outer circumferential surface of the cylinder body 11 to block the hole 235, and at the same time the electric telescopic rod I33 is stretched, driving the ring 38 to move downward, so that it contacts the transmission plate 223 located below it, and drives the transmission plate 223 to be close to the outer surface of the body I221, and partially blocks the vent hole I224. When the transmission plate 223 moves, it also drives the corresponding rubber plug 227 to separate from the corresponding vent hole III228, so that The vent hole III 228 is connected to the outside world. At this time, when the exhaust fan 5 is working, the heat in the power distribution station can only enter the fixed cylinder 22 through the vent hole III 228 and the unblocked vent hole I 224, and then be discharged after passing through the cylinder 11. Since the fixed cylinder 22 rotates to the lower end of the cylinder 11, the distance between the vent hole III 228, the vent hole I 224 and the equipment in the power distribution station is shortened, and the air inlet end on the slide cylinder 23 is separated from the outside world. Only the air can enter the interior of the device from the vent hole III 228 and the vent hole I 224, which is relatively normal. In this state, the total area of ​​the air inlet end of the device is reduced, so the suction force at the positions of the vent holes III 228 and the vent holes I 224 is enhanced, which accelerates the heat dissipation efficiency. At the same time, the ring 38 pushes the corresponding transmission plate 223 to move, so that the vent holes III 228 located below the temperature sensor 37 are exposed. The cross-sectional area of ​​the vent holes III 228 is larger than the cross-sectional area of ​​the vent holes I 224. When heat is dissipated, the exposed vent holes III 228 and the high-temperature area below the temperature sensor 37 have higher heat dissipation efficiency, thereby achieving the purpose of accelerating the heat dissipation in local areas.

[0039] After the local temperature drops, the temperature sensor 37 feeds back a signal to the controller, which is then controlled by the controller to reverse the operation in the above manner to move it to the initial state and continue temperature collection and monitoring.
