Description

Technical Field

[0001] The present invention relates to the technical field of power distribution, and in particular to a power distribution switch control device. Background Art

[0002] The power distribution cabinet belongs to a kind of power distribution switch control device. The power distribution switch control device is mainly used for the power distribution of the power system. After the power distribution cabinet is used for a long time, the lines inside the power distribution cabinet may be aged. The aging of the lines is likely to cause a fire. Therefore, the patent with the publication number of CN116093766A discloses a power distribution cabinet with an automatic fire extinguishing system, including a cabinet body. A top box is arranged on the top of the cabinet body and is connected by bolts. A base is arranged at the bottom of the cabinet body. A rectangular side plate one is arranged on the left side of the cabinet body and is connected by welding. A rectangular side plate two is arranged on the right side of the cabinet body and is connected by welding. A controller is arranged in the middle of the inner wall of the base. A heat-sensitive temperature sensor is arranged at the top of the controller. An aerosol ejector one is arranged at the left rear end of the inner wall of the base. An aerosol ejector two is arranged at the right rear end of the inner wall of the base. An aerosol ejector three is arranged at the left front end of the inner wall of the base.

[0003] When a fire breaks out inside the above-mentioned power distribution cabinet, the heat-sensitive temperature sensor will be induced, and the controller can control multiple ejectors to eject an aerosol mixture to extinguish the fire inside the power distribution cabinet. However, if the staff is close to the power distribution cabinet when a fire breaks out inside the power distribution cabinet, and at this time, since the cabinet door is open, the outside air is likely to make the fire more intense. Therefore, the staff can close the cabinet door to isolate the air as much as possible, so that the fire extinguishing effect is better. However, because there is a risk of explosion at any time when a fire breaks out inside the power distribution cabinet, the staff is likely to be injured when closing the cabinet door during a fire. Therefore, a power distribution switch control device that can automatically isolate the air inside the power distribution cabinet when a fire breaks out is now developed. Summary of the Invention

[0004] The present invention provides a power distribution switch control device that can automatically isolate the air inside the power distribution cabinet when a fire breaks out, so as to overcome the defect that when a fire breaks out in a power distribution cabinet with an existing automatic fire extinguishing system, the staff needs to manually close the cabinet door to isolate the air.

[0011] More preferably, it further includes a pushing-away mechanism for pushing away the staff. The pushing-away mechanism includes a fixed block which is connected to the side of the power distribution cabinet away from the downward moving frame. A pushing-away frame is rotatably connected to the top of the fixed block. A connecting torsion spring is connected between the pushing-away frame and the fixed block. A rotating assembly for driving the pushing-away frame to rotate is arranged between the pushing-away frame and the power distribution cabinet.

[0012] More preferably, the rotating assembly includes a one-way gear which is connected to the pushing-away frame near the side close to the downward-moving frame. A fixing member is connected to the side of the power distribution cabinet near the one-way gear. A winder is rotatably connected to the fixing member. A missing gear is connected to the side of the winder near the one-way gear. The missing gear meshes with the one-way gear. A return torsion spring is connected between the top of the winder and the fixing member. A connecting pull rope is wound around the winder. A guiding member is arranged on the side of the power distribution cabinet near the one-way gear. The connecting pull rope bypasses the guiding member, and the end of the connecting pull rope away from the winder is connected to the downward-moving frame.

Detailed implementation manners

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1: A distribution switch control device, as Figures 1 - 5 shown, includes a power distribution cabinet 1, a connecting plate 11, a heat-sensitive thermostat 12, an aerosol injector 13, a cabinet door 14, a protective frame 15, an electric push rod 16, a pressing frame 17, a driving lead screw 18, a connecting rod 19, a threaded sleeve 110, a connecting member 111, a buzzer 113 and a guide rod 114. Six ventilation openings are provided on both the left and right sides of the power distribution cabinet 1. The cabinet door 14 is rotatably connected to the left front side of the power distribution cabinet 1. The connecting plate 11 is welded to the lower part inside the power distribution cabinet 1. The heat-sensitive thermostat 12 is provided in the middle of the connecting plate 11. The aerosol injectors 13 are symmetrically arranged in the front and back on both the left and right sides of the bottom inside the power distribution cabinet 1. The heat-sensitive thermostat 12 and the aerosol injectors 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 protective frame 15 is welded to the upper rear part of the power distribution cabinet 1. The electric push rod 16 is connected to the left front part of the protective frame 15 through a bolt. The electric push rod 16 and the heat-sensitive thermostat 12 are electrically connected through a control module. The bottom of the telescopic rod of the electric push rod 16 is connected to the pressing frame 17. The left side of the top of the cabinet door 14 is fixedly connected to the connecting rod 19. The driving lead screw 18 is welded to the top of the connecting rod 19. The threaded sleeve 110 is threadedly connected to the driving lead screw 18. The rear part of the threaded sleeve 110 is connected to the connecting member 111. The top of the connecting member 111 and the bottom of the pressing frame 17 are in pressing cooperation. The guide rod 114 is fixedly connected to the left front side of the top of the power distribution cabinet 1. The guide rod 114 and the connecting member 111 are slidably connected. The buzzer 113 is connected to the middle of the upper front part of the power distribution cabinet 1. An alarm is issued through the buzzer 113. The buzzer 113 and the heat-sensitive thermostat 12 are electrically connected through a control module.

[0033] When maintenance personnel need to repair the internal circuits of the power distribution cabinet 1, the cabinet door 14 can be opened. When the cabinet door 14 is opened, it drives the connecting rod 19 to rotate. The rotation of the connecting rod 19 drives the driving lead screw 18 to rotate. The rotation of the driving lead screw 18 causes the threaded sleeve 110 to move upward. The upward movement of the threaded sleeve 110 drives the connecting member 111 to move upward. After the cabinet door 14 is fully opened, the connecting member 111 moves upward to the highest point. Subsequently, the maintenance personnel can cut off the power supply of the power distribution cabinet 1 and then start repairing the internal circuits of the power distribution cabinet 1. After the repair is completed, the maintenance personnel can power on the power distribution cabinet 1. If a short circuit or other faults occur inside the power distribution cabinet 1 after it is powered on, it is easy to generate sparks and cause a fire. When the heat-sensitive temperature sensor 12 senses it, it will control the aerosol ejector 13 to eject an aerosol mixture for fire extinguishing through the control module. At the same time, the heat-sensitive temperature sensor 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 beeping sound to remind the maintenance personnel of the fire situation. The telescopic rod of the electric push rod 16 starts to extend, driving the extrusion frame 17 to move downward. When the extrusion frame 17 contacts the top of the connecting member 111, it drives the connecting member 111 to move downward. The downward movement of the connecting member 111 drives the threaded sleeve 110 to move downward. The downward movement of the threaded sleeve 110 drives the driving lead screw 18 to reverse and reset. The reverse reset of the driving lead screw 18 drives the cabinet door 14 to reverse and close automatically through the connecting rod 19. In this way, the inside of the power distribution cabinet 1 can be automatically isolated from the air, reducing the entry of external air into the power distribution cabinet 1. When there is not enough oxygen inside the power distribution cabinet 1, the fire will gradually weaken, making the fire extinguishing effect of the aerosol ejector 13 better. Moreover, it can also isolate the fire and prevent the fire from spreading to other power distribution switch control devices. After the fire is extinguished, the temperature inside the power distribution cabinet 1 drops. When the heat-sensitive temperature sensor 12 senses it, it controls the buzzer 113 and the aerosol ejector 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: On the basis of Embodiment 1, as Figures 6 - 7As shown in the figure, it further includes a closing mechanism for blocking the ventilation openings of the power distribution cabinet 1. The closing mechanism includes a driving assembly, a rotating plate 32, a sealing member 34, and a reset torsion spring 35. Rotating plates 32 are rotatably connected to both the left and right sides of the power distribution cabinet 1. Sealing members 34 are connected to both the front and rear sides of the bottom of the rotating plate 32. The sealing members 34 are used to block the ventilation openings. The sealing members 34 can be rubber plates. Two reset torsion springs 35 are connected between the rotating plate 32 and the power 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 downward moving frame 3, a rack 31, and a full gear 33. A downward moving frame 3 is welded to the rear side of the extrusion frame 17. Racks 31 are welded to both the left and right sides of the downward moving frame 3. Full gears 33 are welded to the front parts of the rotating plates 32. The full gears 33 are meshed with the racks 31.

[0035] When a fire breaks out inside the power distribution cabinet 1, although the cabinet door 14 is closed, some air will still enter through the ventilation openings. Therefore, the closing mechanism is provided to further block the ventilation openings. When the extrusion frame 17 moves downward, it will drive the downward moving frame 3 to move downward. The downward movement of the downward moving frame 3 drives the rack 31 to move downward. When the rack 31 moves downward and meshes 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 sealing member 34 to block the ventilation opening, and the reset torsion spring 35 is twisted. In this way, the purpose of isolating air can be achieved. When the extrusion frame 17 moves upward, it will drive the downward moving frame 3 to move upward and reset. The upward movement of the downward moving frame 3 drives the rack 31 to move upward. The upward movement of the rack 31 drives the full gear 33 to rotate and reset. Moreover, 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 ventilation opening.

[0036] As Figures 4 - 5 As shown in the figure, it further includes a power-off switch 112. The power-off switch 112 is connected to the left front side of the top of the power distribution cabinet 1. The power-off switch 112 is located to the right of the driving lead screw 18. The top of the power-off switch 112 and the bottom of the extrusion frame 17 are in extrusion fit. When the extrusion frame 17 moves downward and presses on the power-off switch 112, the power-off switch 112 can automatically disconnect the circuit inside the power distribution cabinet 1 to achieve the purpose of power-off protection.

[0037] As Figures 8 - 9As shown in the figure, it further 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 to the lower side of the right front part of the power 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. A rotating assembly for driving the pushing frame 4 to rotate is provided between the pushing frame 4 and the right side of the power distribution cabinet 1. The rotating assembly includes a one-way gear 43, a missing gear 44, a fixing member 45, a winder 46, a connecting pull rope 47, a return torsion spring 48 and a guiding member 49. A one-way gear 43 is welded to the upper right part of the pushing frame 4. A fixing member 45 is fixedly connected to the right front part of the power distribution cabinet 1. A winder 46 is rotatably connected to the fixing member 45. A missing gear 44 is connected to the bottom of the winder 46. The missing gear 44 meshes with the one-way gear 43. A return torsion spring 48 is connected between the top of the winder 46 and the fixing member 45. A connecting pull rope 47 is wound around the winder 46. A guiding member 49 is connected to the right front part of the power distribution cabinet 1. The guiding member 49 is located in front of the fixing member 45. The connecting pull rope 47 bypasses upward along the lower direction of the guiding member 49. The upper end of the connecting pull rope 47 is connected to the moving-down frame 3.

[0038] In the case where the fire is relatively small, the staff may not have noticed yet and will always be in a state of being close to the power distribution cabinet 1. Therefore, a pushing mechanism is provided. When the moving-down frame 3 moves downward, it will pull the upper end of the connecting pull rope 47 downward. The connecting pull rope 47 will drive the winder 46 to rotate, and the return torsion spring 48 will be twisted. When the winder 46 rotates to drive the missing gear 44 to rotate, when the missing gear 44 rotates and meshes with the one-way gear 43, it will drive the pushing frame 4 to swing forward through the one-way gear 43, and the connecting torsion spring 42 will be twisted. When the pushing frame 4 swings forward, it will push the legs of the staff forward, so that the staff can know the situation and move away from the power distribution cabinet 1 by themselves. When the missing gear 44 and the one-way gear 43 are separated, under the action of the connecting torsion spring 42, it drives the pushing frame 4 to reverse and reset. Through the cooperation between the missing gear 44 and the one-way gear 43, it can realize that the pushing frame 4 swings forward intermittently to push the staff away. When the moving-down frame 3 moves upward and resets to release the connecting pull rope 47, under the action of the return torsion spring 48, it drives the winder 46 to reverse and reset to wind up the connecting pull rope 47. When the winder 46 reverses, it 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 rotate idly, and the pushing frame 4 will not rotate.

[0039] Such as Figures 10 - 11As shown, it further includes a protection mechanism for protecting the aerosol injector 13. The protection mechanism includes a protection member 5, a connecting seat 51, a support stay cord 52, and a fixed torsion spring 53. The left and right sides of the lower part inside the power distribution cabinet 1 are both connected with a connecting seat 51. A protection member 5 for protecting the upper part of the aerosol injector 13 is rotatably connected to each connecting seat 51. Fixed torsion springs 53 are connected between the front and rear sides of the protection member 5 and the connecting seat 51. Support stay cords 52 are connected between the upper part of the protection member 5 and the rotating plate 32. Guide pulleys are rotatably connected to the front upper parts of the connecting seats 51. The support stay cords 52 bypass the guide pulleys and pass through the power distribution cabinet 1.

[0040] By covering the upper part of the aerosol injector 13 with the protection member 5, the aerosol injector 13 can be protected. When the staff repairs the power distribution cabinet 1, it can prevent repair tools from accidentally falling and hitting the aerosol injector 13. Therefore, when the rotating plate 32 swings downward, it will drive the protection member 5 to rotate through the support stay cord 52 and no longer block the upper part of the aerosol injector 13, and the fixed torsion spring 53 is twisted. When the rotating plate 32 swings upward and resets, under the action of the fixed torsion spring 53, it drives the rotating plate 32 to reverse and reset.

[0041] As Figure 12 shown, it further 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 pushing-away frame 4 are both connected with a support rod 6. A buffer rod 61 is slidably connected between the support rods 6. A buffer pad 62 is provided at the front part of the buffer rod 61. Elastic members 63 are connected between the left and right sides of the rear part of the buffer rod 61 and the pushing-away frame 4.

[0042] When the pushing-away frame 4 swings forward, it will drive the buffer rod 61 and the buffer pad 62 to swing forward and contact the legs of the staff. The elastic member 63 deforms adaptively. The legs of the staff can be buffered and protected through the buffer rod 61 and the buffer pad 62 to avoid leg injuries.

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