[0060] In use, when the transformer installed above the support 2 is on fire, the control assembly controls the internal circuit of the cabinet 1 to be cut off, then the control assembly controls the cutting assembly to work to cut off the connecting line between the cabinet 1 and the transformer, so that the flame is prevented from burning to the inside of the cabinet 1 along the connecting line, after being cut off, the control assembly drives the retracting and releasing assembly to release the steel cable 5, at this time, under the action of gravity, the cabinet 1 is lowered, so that the cabinet 1 is away from the transformer on fire, and finally the cabinet 1 is located on the ground, so that the high-temperature flame generated by the transformer on fire is prevented from baking the cabinet 1, so that the devices in the cabinet 1 are prevented from being damaged, thereby achieving the protection of the cabinet 1.

[0061] As shown in Figure 1 , the retracting and releasing assembly comprises a mounting frame 7, a winding wheel 8, a transmission rod 9 and a first motor 10.

[0062] The mounting frame 7 is symmetrically arranged below the cabinet 1, the winding wheel 8 is rotatably installed in the mounting frame 7, the other end of the steel cable 5 is fixedly connected with the winding wheel 8, the steel cable 5 is wound in the winding wheel 8, the transmission rod 9 is fixedly connected between the opposite two winding wheels 8, and the first motor 10 is fixedly installed outside the mounting frame 7 and is fixedly connected with the middle part of one side of the opposite winding wheel 8.

[0063] The first motor 10 is started to make the output shaft positively rotate to drive the connected winding wheel 8 to rotate, so as to drive the other winding wheel 8 to rotate through the transmission rod 9, so that the wound steel cable 5 is released, and conversely, the output shaft of the first motor 10 is reversely rotated to realize the winding of the steel cable 5.

[0064] As shown in Figure 3 and Figure 4 , the cutting assembly comprises a sliding rail 13, a lead screw 14, a sliding block 15, a cutter 16 and a second motor 17.

[0065] The slide rail 13 is symmetrically fixedly installed on one side of the cabinet body 1, the lead screw 14 is rotatably installed inside the slide rail 13, the sliding block 15 is symmetrically threadedly sleeved outside the lead screw 14, the cutter 16 is fixedly connected between the upper and lower two opposite sliding blocks 15, the second motor 17 is fixedly connected on one side of the slide rail 13, the output shaft of the second motor 17 is fixedly connected with one end of the corresponding lead screw 14, and the connecting line between the transformer and the cabinet body 1 is located between the pair of cutters 16.

[0066] The second motor 17 is started to make the output shaft of the second motor 17 drive the lead screw 14 to rotate in the positive direction, so as to drive the pair of sliding blocks 15 to move close to each other, and then drive the cutter 16 to move, and finally the two cutters 16 move close to each other to cut off the connecting line.

[0067] As shown in Figures 1 to 4 , the control assembly comprises a temperature sensor 11, a flame sensor 12, a controller not shown in the figure, and a power supply assembly;

[0068] The temperature sensor 11 is arranged on the top of the cabinet body 1 and is used to monitor the temperature around the transformer. The threshold value of the temperature sensor 11 is set to 200℃, which is higher than the normal operating temperature of the transformer. The flame sensor 12 is arranged on the top of the cabinet body 1 and is used to monitor the flame around the transformer. The controller is arranged in the inside of the cabinet body 1 and is used to cut off the circuit in the inside of the cabinet body 1 and control the first motor 10 and the second motor 17 to work in cooperation with the temperature sensor 11 and the flame sensor 12. The controller is a PLC controller. The power supply assembly is arranged below the cabinet body 1 and is used to provide power supply for the temperature sensor 11, the flame sensor 12, the first motor 10 and the second motor 17.

[0069] In use, when the transformer is on fire, the temperature around the transformer is higher than 200℃ and is accompanied by sparks and flames. At this time, the temperature sensor 11 and the flame sensor 12 are both triggered, and the controller cuts off the circuit in the inside of the cabinet body 1 and controls the first motor 10 and the second motor 17 to work.

[0070] As shown in Figure 3 , the power supply assembly comprises a storage battery 18 and a photovoltaic panel 19.

[0071] The storage battery 18 is arranged below the cabinet body 1 and provides power supply for the temperature sensor 11, the flame sensor 12, the first motor 10 and the second motor 17. The photovoltaic panel 19 is arranged below the cabinet body 1 and is used to convert solar energy into electrical energy and store the electrical energy in the storage battery 18.

[0072] So that when the transformer and the inside of the cabinet body 1 are both powered off, the subsequent protection measures for the cabinet body 1 can be ensured to be executed through the power supply of the storage battery 18.

[0073] As shown in Figure 1 and Figure 3As shown, the bottom of the cabinet 1 is fixedly installed with a frame 20, the inside of the frame 20 is provided with a channel, the outer side of the frame 20 is equidistantly surrounded by spray holes 21 which are in communication with the channel, and the lower side of the frame 20 is provided with a water supply assembly which can inject water into the channel.

[0074] If the season of the fire is autumn, there are dry grasses around the transformer, after the transformer is on fire, the sparks will fall on the dry grasses and ignite the dry grasses, so that the flames will be formed around the cabinet 1, and the cabinet 1 will be roasted by the flames even if it is far away from the transformer;

[0075] Therefore, when the cabinet 1 is lowered, the water supply assembly injects water into the channel, and the water is sprayed out through the spray holes 21, so that the surrounding dry grasses are sprayed with water, and the dry grasses are wetted, thereby avoiding the dry grasses from being ignited, and further achieving the protection of the cabinet 1. After the cabinet 1 is lowered to the ground, the water continues to be sprayed outward, ensuring that the surrounding of the cabinet 1 is wet, and better protecting the cabinet 1.

[0076] As shown in the drawings, Figure 3 The water supply assembly comprises a box body 22, a collecting port, a flow guide frame 23, a filter screen 24, a pump body 25, and a hose 26.

[0077] The box body 22 is arranged below the cabinet 1, the mounting bracket 7, the storage battery 18, and the photovoltaic panel 19 are fixedly installed on the top of the box body 22, the collecting ports are symmetrically formed on the box body 22 for collecting rainwater, the flow guide frame 23 is installed on the box body 22 for guiding the rainwater into the collecting ports, the filter screen 24 is arranged in the collecting ports for filtering the rainwater to avoid dry leaves entering the box body 22, and the pump body 25 is installed on the top of the box body 22, the water suction end of the pump body 25 is communicated with the inside of the box body 22 through a suction pipe, the water delivery end of the pump body 25 is connected with the inner side of the frame 20 through the hose 26, the hose 26 is in communication with the channel, and the controller can control the pump body 25.

[0078] At the same time when the first motor 10 is started, the controller controls the pump body 25 to work, the rainwater collected in the box body 22 is pumped out through the suction pipe, and the rainwater is injected into the channel through the hose 26, so as to realize water injection. The rainwater is introduced through the flow guide frame 23, and then filtered through the filter screen 24 and collected in the box body 22.

[0079] As shown in the drawings, Figure 4 The frame 20 can cover the storage battery 18, the photovoltaic panel 19, the pump body 25, and the hose 26.

[0080] So that after the cabinet 1 falls on the box body 22, the frame 20 can cover the storage battery 18, the photovoltaic panel 19, the pump body 25, and the hose 26, achieving the protection of the storage battery 18, the photovoltaic panel 19, the pump body 25, and the hose 26, and avoiding the damage of the sparks to the storage battery 18, the photovoltaic panel 19, the pump body 25, and the hose 26.

[0081] AsFigure 1 As shown, the lead screw 14 is symmetrically provided with threads in opposite directions.

[0082] This allows the lead screw 14 to drive a pair of sliders 15 to move closer to each other when it rotates clockwise.

[0083] like ​ As shown, the first motor 10 is specifically configured as a motor with a power failure brake.

[0084] When the transformer is in normal use, the first motor 10 is de-energized and its output shaft is locked, thus ensuring that the steel cable 5, together with the locking buckle 6, can lift the cabinet 1, so that the cabinet 1 is stably positioned at a high position.

[0085] Working principle: When the transformer installed above the bracket 2 catches fire, the surrounding temperature exceeds 200℃ and is accompanied by sparks and flames. At this time, both the temperature sensor 11 and the flame sensor 12 are triggered, and the controller cuts off the circuit inside the cabinet 1. Then, the second motor 17 is controlled to work. The output shaft of the second motor 17 drives the lead screw 14 to rotate forward, thereby driving a pair of sliders 15 to move closer to each other, which in turn moves the cutter 16. The two cutters 16 move closer to each other and finally cut the connecting wire, preventing the flame from burning into the cabinet 1 along the connecting wire. After cutting, the controller controls the first motor 10 to work, causing its output shaft to rotate forward, driving the connected winding wheel 8 to rotate, which in turn drives the other winding wheel 8 to rotate, so that the wound steel cable 5 is released. At this time, under the action of gravity, the cabinet 1 descends, moving the cabinet 1 away from the burning transformer. Finally, the cabinet 1 is located on the ground. By moving the cabinet 1 away from the burning transformer, the high temperature flames generated by the burning transformer can be prevented from baking the cabinet 1, causing damage to the components inside the cabinet 1, thereby protecting the cabinet 1.

[0086] If the fire occurs in autumn, and there is dry grass around the transformer, the sparks from the transformer will fall on the dry grass and ignite it, causing flames to form around cabinet 1. Even if cabinet 1 is far away from the transformer, it will still be exposed to the heat of the flames.

[0087] Therefore, when cabinet 1 descends, the controller controls pump 25 to work, which, together with the suction pipe, draws out the rainwater collected in cabinet 22 and injects it into the channel with hose 26, thus achieving water injection. The water is sprayed out through nozzle 21, which wets the surrounding dry grass, thereby preventing the dry grass from being ignited and protecting cabinet 1. After cabinet 1 descends to the ground, water continues to spray outward to keep the area around cabinet 1 moist, thus better protecting cabinet 1.

[0088] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
