[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1: A power distribution switch control device, such as Figure 1-Figure 5 As shown, it includes a distribution cabinet 1, a connecting plate 11, a thermal temperature sensor 12, an aerosol injector 13, a cabinet door 14, a protective frame 15, an electric push rod 16, an extrusion frame 17, a driving screw 18, a connecting rod 19, a threaded sleeve 110, a connecting piece 111, a buzzer 113 and a guide rod 114. The distribution cabinet 1 has six ventilation holes on both sides. The cabinet door 14 is rotatably connected to the left front side of the distribution cabinet 1. A connecting plate 11 is welded at the lower part of the distribution cabinet 1. A thermal temperature sensor 12 is arranged in the middle of the connecting plate 11. Aerosol injectors 13 are symmetrically arranged on the left and right sides of the bottom of the distribution cabinet 1. The thermal temperature sensor 12 and the aerosol injector 13 are electrically connected through a control module. The upper part of the aerosol injector 13 is connected to the connecting plate 11. The aerosol injector 13 is used for fire extinguishing. The upper part of the rear of the distribution cabinet 1 is welded. There is a protective frame 15, and an electric push rod 16 is connected to the left front part of the protective frame 15 by bolts. The electric push rod 16 and the thermal thermostat 12 are electrically connected through a control module. The bottom of the telescopic rod of the electric push rod 16 is connected to an extrusion frame 17. A connecting rod 19 is fixedly connected to the left side of the top of the cabinet door 14, and a driving screw rod 18 is welded to the top of the connecting rod 19. A threaded sleeve 110 is threadedly connected to the driving screw rod 18, and a connecting piece 111 is connected to the rear of the threaded sleeve 110. The top of the connecting piece 111 and the bottom of the extrusion frame 17 are extruded and matched. A guide rod 114 is fixedly connected to the left front side of the top of the distribution cabinet 1, and the guide rod 114 and the connecting piece 111 are slidably connected. A buzzer 113 is connected to the middle of the upper front part of the distribution cabinet 1, and an alarm is issued through the buzzer 113. The buzzer 113 and the thermal thermostat 12 are electrically connected through the control module.

[0033] When the staff needs to repair the internal circuit of the power distribution cabinet 1, the cabinet door 14 can be opened. When the cabinet door 14 is opened, the connecting rod 19 will be driven to rotate, and the rotation of the connecting rod 19 will drive the driving screw 18 to rotate. The rotation of the driving screw 18 will drive the threaded sleeve 110 to move upward, and the upward movement of the threaded sleeve 110 drives the connecting piece 111 to move upward. After the cabinet door 14 is fully opened, the connecting piece 111 moves upward to the highest point. Then, the staff can cut off the power supply of the power distribution cabinet 1 and start to repair the internal circuit of the power distribution cabinet 1. After the maintenance is completed, the staff can power on the power distribution cabinet 1. After the power distribution cabinet 1 is powered on, if there is a short circuit or other faults in the power distribution cabinet 1, sparks are likely to occur, thereby causing a fire. When the thermal thermometer 12 senses it, it will control the aerosol injector 13 to spray an aerosol mixture through the control module to extinguish the fire. At the same time, the thermal thermometer 12 will also control the electric push rod 16 to start working and the buzzer 113 to start working through the control module. The buzzer 113 will emit a buzzing sound to remind In case of fire, the telescopic rod of the electric push rod 16 begins to extend, driving the extrusion frame 17 to move downward. When the extrusion frame 17 contacts the top of the connecting piece 111, the connecting piece 111 is driven to move downward. The connecting piece 111 moves downward and drives the threaded sleeve 110 to move downward. The threaded sleeve 110 moves downward and drives the driving screw rod 18 to reverse and reset. The driving screw rod 18 reverses and resets and drives the cabinet door 14 to reverse and automatically close through the connecting rod 19. In this way, the air inside the distribution cabinet 1 can be automatically isolated to reduce the outside air. The gas enters the distribution cabinet 1, so when there is insufficient oxygen inside the distribution cabinet 1, the fire will gradually become smaller, making the aerosol injector 13 more effective in extinguishing the fire, and it can also isolate the fire to prevent the fire from spreading to other distribution switch control equipment. After the fire is extinguished, the temperature inside the distribution cabinet 1 drops. After the thermistor 12 senses it, it controls the buzzer 113 and the aerosol injector 13 to stop working through the control module, and controls the telescopic rod of the electric push rod 16 to shorten and reset, driving the extrusion frame 17 to move upward and reset.

[0034] Embodiment 2: Based on embodiment 1, Figure 6-Figure 7As shown, it also includes a closing mechanism for blocking the ventilation opening of the distribution cabinet 1, and the closing mechanism includes a driving assembly, a rotating plate 32, a sealing member 34 and a reset torsion spring 35. The left and right sides of the distribution cabinet 1 are rotatably connected with the rotating plates 32, and the front and rear sides of the bottom of the rotating plate 32 are connected with sealing members 34. The sealing member 34 is used to block the ventilation opening. The sealing member 34 can be a rubber plate. Two reset torsion springs 35 are connected between the rotating plate 32 and the distribution cabinet 1. A driving assembly for driving the rotating plate 32 to rotate is provided between the front part of the rotating plate 32 and the extrusion frame 17; the driving assembly includes a lower moving frame 3, a rack 31 and a full gear 33. The lower moving frame 3 is welded to the rear side of the extrusion frame 17, and the racks 31 are welded to the left and right sides of the lower moving frame 3. The front part of the rotating plate 32 is welded with a full gear 33, and the full gear 33 is meshed with the rack 31.

[0035] When a fire occurs inside the distribution cabinet 1, although the cabinet door 14 is closed, some air will still enter the vent. Therefore, a closing mechanism is provided to further block the vent. When the extrusion frame 17 moves downward, it will drive the lower frame 3 to move downward, and the lower frame 3 moves downward to drive the rack 31 to move downward. When the rack 31 moves downward and engages with the full gear 33, it will drive the full gear 33 to rotate. The rotation of the full gear 33 drives the rotating plate 32 to rotate. The rotating plate 32 will swing downward to drive the seal 34 to block the vent, and the reset torsion spring 35 will be twisted, so as to achieve the purpose of isolating the air. When the extrusion frame 17 moves upward, it will drive the lower frame 3 to move upward and reset. The lower frame 3 moves upward to drive the rack 31 to move upward. The rack 31 moves upward to drive the full gear 33 to rotate and reset, and under the action of the reset torsion spring 35, it will also drive the rotating plate 32 to reverse and reset and no longer block the vent.

[0036] like Figure 4-Figure 5 As shown, a power-off switch 112 is also included. The power-off switch 112 is connected to the left front side of the top of the distribution cabinet 1. The power-off switch 112 is located on the right side of the driving screw 18. The top of the power-off switch 112 and the bottom of the extrusion frame 17 are squeezed together. When the extrusion frame 17 moves downward and squeezes the power-off switch 112, the power-off switch 112 can automatically disconnect the circuit in the distribution cabinet 1, thereby achieving the purpose of power-off protection.

[0037] like Figure 8-Figure 9As shown, it also includes a pushing mechanism for pushing the staff forward, the pushing mechanism includes a pushing frame 4, a fixed block 41, a connecting torsion spring 42 and a rotating assembly, a fixed block 41 is welded on the lower right front side of the distribution cabinet 1, the top of the fixed block 41 is rotatably connected to the pushing frame 4, a connecting torsion spring 42 is connected between the lower part of the pushing frame 4 and the top of the fixed block 41, and a rotating assembly for driving the pushing frame 4 to rotate is provided between the pushing frame 4 and the right side of the distribution cabinet 1; the rotating assembly includes a one-way gear 43, a missing gear 44, a fixing member 45, a reel 46, a connecting pull rope 47, a return torsion spring 48 and a guide Part 49, a one-way gear 43 is welded on the upper right part of the push-off frame 4, a fixing part 45 is fixedly connected to the right front part of the distribution cabinet 1, and a reel 46 is rotatably connected to the fixing part 45, and a missing gear 44 is connected to the bottom of the reel 46, and the missing gear 44 is meshed with the one-way gear 43. A return torsion spring 48 is connected between the top of the reel 46 and the fixing part 45, and a connecting rope 47 is wound on the reel 46. A guide part 49 is connected to the right front part of the distribution cabinet 1, and the guide part 49 is located in front of the fixing part 45. The connecting rope 47 is bypassed upward along the bottom of the guide part 49, and the upper end of the connecting rope 47 is connected to the lower frame 3.

[0038] When the fire is relatively small, the staff may not find it and will always be in a state close to the distribution cabinet 1. Therefore, a push-away mechanism is provided. When the lower moving frame 3 moves downward, the upper end of the connecting pull rope 47 will be pulled downward, and the connecting pull rope 47 will drive the reel 46 to rotate, and the return torsion spring 48 will be twisted. The rotation of the reel 46 drives the missing gear 44 to rotate. When the missing gear 44 rotates and engages with the one-way gear 43, the push-away frame 4 will be driven to swing forward through the one-way gear 43, and the connecting torsion spring 42 will be twisted. The push-away frame 4 swings forward and pushes the staff's legs forward, so that the staff can know the situation and stay away from the distribution cabinet by themselves. In the electrical cabinet 1, when the missing gear 44 and the one-way gear 43 are separated, under the action of the connecting torsion spring 42, the push-off frame 4 is driven to reverse and reset. Through the cooperation between the missing gear 44 and the one-way gear 43, the push-off frame 4 can be intermittently swung forward to push the staff away. When the lower frame 3 moves upward to reset and release the connecting pull rope 47, under the action of the return torsion spring 48, the winder 46 is driven to reverse and reset to rewind the connecting pull rope 47. The reversal of the winder 46 drives the missing gear 44 to reverse. When the missing gear 44 reverses and meshes with the one-way gear 43 again, it will drive the outer gear ring of the one-way gear 43 to idle, and the push-off frame 4 will not rotate.

[0039] like Figure 10-11As shown, a protective mechanism for protecting the aerosol sprayer 13 is also included, and the protective mechanism includes a protective member 5, a connecting seat 51, a support pull rope 52 and a fixed torsion spring 53. The left and right sides of the lower part of the distribution cabinet 1 are connected to the connecting seat 51, and the connecting seat 51 is rotatably connected to the protective member 5 for protecting the upper part of the aerosol sprayer 13. Fixed torsion springs 53 are connected between the front and rear sides of the protective member 5 and the connecting seat 51, and the support pull rope 52 is connected between the upper part of the protective member 5 and the rotating plate 32. The upper front part of the connecting seat 51 is rotatably connected to a wire pulley, and the support pull rope 52 passes around the wire pulley and passes through the distribution cabinet 1.

[0040] By covering the aerosol injector 13 with the protective member 5, the aerosol injector 13 can be protected. When the staff is repairing the distribution cabinet 1, it can prevent the maintenance tools from accidentally falling and hitting the aerosol injector 13. Therefore, when the rotating plate 32 swings downward, the protective member 5 will be driven to rotate through the support rope 52 and will no longer block the aerosol injector 13. The fixed torsion spring 53 is twisted. When the rotating plate 32 swings upward and resets, the rotating plate 32 is driven to reverse and reset under the action of the fixed torsion spring 53.

[0041] like Fig.12 As shown, it also includes a support rod 6, a buffer rod 61, a buffer pad 62 and an elastic member 63. The left and right sides of the front lower part of the push-off frame 4 are connected to the support rod 6, the buffer rod 61 is slidably connected between the support rods 6, the buffer pad 62 is provided at the front of the buffer rod 61, and the elastic member 63 is connected between the left and right sides of the rear part of the buffer rod 61 and the push-off frame 4.

[0042] When the push-off frame 4 swings forward, the buffer rod 61 and the buffer pad 62 are driven to swing forward and contact the legs of the staff, and the elastic member 63 deforms adaptively, and the buffer rod 61 and the buffer pad 62 can provide buffering protection for the legs of the staff to avoid leg injuries.

[0043] It should be understood that the above description is only for exemplary purposes and is not meant to limit the present invention. Those skilled in the art will appreciate that variations of the present invention will be included within the scope of the claims herein.
