Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet technology, specifically an electrical cabinet with a power failure protection mechanism. Background Technology

[0002] For safety reasons, electrical cabinets are typically equipped with internal power-off devices. However, these devices cannot completely eliminate the risk of fire. If a fire breaks out inside the cabinet and is not extinguished promptly, it can cause significant safety hazards and economic losses.

[0003] Therefore, to ensure the safety of electrical cabinets, fire extinguishers are usually placed next to them to promptly eliminate potential safety hazards in the event of an open flame. Regular inspections and early warning systems are also necessary to ensure the safety of electrical cabinets. Failure to detect safety hazards in a timely manner can still result in significant economic losses.

[0004] To address this, we propose an electrical cabinet that can be powered off and has an active protection mechanism to overcome the shortcomings of existing electrical cabinets. Utility Model Content

[0005] The technical problem solved by this utility model is to provide an electrical cabinet with a power failure protection mechanism to solve the problems raised in the prior art.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] An electrical cabinet with a power failure protection mechanism includes a cabinet body. Filter plates are fixedly connected to both sides of the cabinet body. An adjustment mechanism is provided on the outside of the filter plates. The adjustment mechanism includes a sealing shell, a linkage rod, a sliding rod, and a moving frame. A power compartment is fixedly connected to the bottom of the sealing shell. A snap-fit ​​plate is rotatably connected to the surface of the sealing shell. A flame-retardant mechanism is provided inside the cabinet body. The flame-retardant mechanism includes an exhaust ring and a gas cylinder.

[0008] Preferably, a fan is fixedly connected to the top of the cabinet, a protective plate for the fan is fixedly connected to the surface of the cabinet, and the sealing shell is fixedly connected to the cabinet. The fan allows the air inside the cabinet to circulate with the outside air, thereby improving the heat dissipation efficiency of the cabinet.

[0009] Preferably, a connecting block is fixedly connected to the surface of the snap-fit ​​plate, and the connecting block is rotatably connected to the linkage rod. A first telescopic spring is fixedly connected to the top end of the linkage rod, and the top end of the first telescopic spring is fixedly connected to the sealing shell. The first telescopic spring provides tension to the top end of the linkage rod, so that the linkage rod quickly drives the connecting block to move, and the snap-fit ​​plates are closed by interleaving each other.

[0010] Preferably, the bottom end of the linkage rod is rotatably connected to a hinge rod, and the bottom of the hinge rod is rotatably connected to the sliding rod. The sliding rod is slidably connected to the sealing shell, and the bottom of the sliding rod is fixedly connected to a toothed plate, which is located inside the power compartment. The toothed plate drives the sliding rod to move up and down, and the linkage rod moves up and down through the transmission control of the hinge rod.

[0011] Preferably, a second telescopic spring is fixedly connected to the bottom of the toothed plate, and the bottom end of the second telescopic spring is fixedly connected to the power chamber. A power gear is rotatably connected inside the moving frame, and the power gear meshes with the toothed plate. A buffer pad of the buffer toothed plate is fixedly connected to the surface of the sealing shell. The second telescopic spring provides a thrust to the toothed plate when the locking plate is closed.

[0012] Preferably, the movable frame is internally fixedly connected to an electric motor that controls the rotation of the power gear, and the power compartment is internally fixedly connected to a slide rail. The movable frame is slidably connected to the slide rail, and the slide rail limits the movement of the movable frame, thereby improving the stability of the sliding of the movable frame.

[0013] Preferably, an iron sheet is fixedly connected to the surface of the movable frame, an electromagnet adapted to the iron sheet is fixedly connected to the surface of the power compartment, a third telescopic spring is fixedly connected inside the power compartment, and the other end of the third telescopic spring is fixedly connected to the movable frame. A reset tube is fixedly connected inside the power compartment. The iron sheet is attracted by the electromagnet to fix the movable frame, so that the power gear meshes with the gear plate.

[0014] Preferably, the bottom of the cabinet is fixedly connected to a storage compartment, and the gas tank is installed inside the storage compartment. The bottom of the gas outlet ring is fixedly connected to a control pipe, and the control pipe passes through the cabinet and is fixedly connected to the gas tank. Through the control pipe, the gas tank is connected to the gas outlet ring, and when carbon dioxide gas needs to be released, the gas inside the gas tank is controlled to enter the gas outlet ring.

[0015] The beneficial effects of this utility model are:

[0016] 1. When the sealed shell needs to be connected, the sliding rod drives the linkage rod to move, causing the snap-fit ​​plate to flip outward, allowing outside air to enter the cabinet through the sealed shell and filter plate. When the sealed shell needs to be closed, the shell can be sealed by several snap-fit ​​plates arranged in an alternating manner. Carbon dioxide gas is released through the gas cylinder and evenly distributed inside the cabinet through the air outlet ring, thus creating an oxygen-deficient state inside, thereby preventing the occurrence of fire or controlling the spread of fire.

[0017] 2. This application protects the fan with a protective plate. The fan allows air to circulate between the inside and outside of the cabinet, improving the cabinet's heat dissipation efficiency. When the locking plate needs to be closed, the first telescopic spring provides tension to the top of the linkage rod, causing the linkage rod to quickly move the connecting block, closing the locking plates in an alternating manner, thus improving the sealing efficiency of the sealing shell. The toothed plate drives the sliding rod to move up and down, and the linkage rod moves up and down through the transmission control of the hinge rod. The second telescopic spring provides thrust to the toothed plate when closing the locking plate, improving the locking plate's closing efficiency. The rotation of the power gear drives the toothed plate to move up and down.

[0018] 3. This application controls the rotation of the power gear by rotating the motor, limits the movement of the moving frame by the slide rail, improves the stability of the moving frame's sliding, fixes the moving frame by attracting the iron plate by the electromagnet, and makes the power gear mesh with the toothed plate. When it is necessary to close the locking plate, the electromagnet is de-energized, and the moving frame is pulled by the third telescopic spring, so that the power gear and the toothed plate are disengaged. The reset tube can provide thrust to the moving frame to facilitate the electromagnet to attract the iron plate. The gas tank is stored and fixed by the storage compartment. The gas tank is connected to the gas outlet ring by the control tube, and when it is necessary to release carbon dioxide gas, the gas inside the gas tank is controlled to enter the gas outlet ring.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0028] It should be noted that, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] like Figure 1-4 As shown, this utility model provides an electrical cabinet with a power failure protection mechanism, including a cabinet body 1. Filter plates 4 are fixedly connected to both sides of the cabinet body 1. Through the filter plates 4, the air inside the cabinet body 1 can circulate with the outside air, thereby dissipating heat from the cabinet body 1.

[0030] Furthermore, a fan 3 is fixedly connected to the top of the cabinet 1, and a protective plate 2 for protecting the fan 3 is fixedly connected to the surface of the cabinet 1. The sealing shell 501 is fixedly connected to the cabinet 1. The fan 3 is protected by the protective plate 2. The fan 3 allows the air inside the cabinet 1 to circulate with the outside air, thereby improving the heat dissipation efficiency of the cabinet 1.

[0031] like Figure 2 and Figure 3As shown, an adjustment mechanism 5 is provided on the outside of the filter plate 4. The adjustment mechanism 5 includes a sealing shell 501, a linkage rod 504, a sliding rod 507, and a moving frame 511. The bottom of the sealing shell 501 is fixedly connected to a power chamber 508. A snap-fit ​​plate 502 is rotatably connected to the surface of the sealing shell 501. The snap-fit ​​plate 502 is fixed by the sealing shell 501. The sealing shell 501 can be sealed by several snap-fit ​​plates 502 arranged in an alternating manner.

[0032] Furthermore, when it is necessary to connect the sealing shell 501, the sliding rod 507 drives the linkage rod 504 to move, causing the snap plate 502 to flip outward, so that outside air can enter the cabinet 1 through the sealing shell 501 and the filter plate 4. The power source for the sliding rod 507 to move up and down is provided by the power chamber 508.

[0033] Furthermore, a connecting block 503 is fixedly connected to the surface of the snap-fit ​​plate 502, and the connecting block 503 is rotatably connected to the linkage rod 504. A first telescopic spring 505 is fixedly connected to the top end of the linkage rod 504, and the top end of the first telescopic spring 505 is fixedly connected to the sealing shell 501. When it is necessary to close the snap-fit ​​plate 502, the first telescopic spring 505 provides a pulling force to the top end of the linkage rod 504, so that the linkage rod 504 quickly drives the connecting block 503 to move, thereby closing the snap-fit ​​plates 502 in an alternating manner and improving the sealing efficiency of the sealing shell 501.

[0034] Furthermore, the bottom end of the linkage rod 504 is rotatably connected to a hinge rod 506, and the bottom of the hinge rod 506 is rotatably connected to the sliding rod 507. The sliding rod 507 is slidably connected to the sealing shell 501. The bottom of the sliding rod 507 is fixedly connected to a toothed plate 509, and the toothed plate 509 is located inside the power chamber 508. The toothed plate 509 drives the sliding rod 507 to move up and down, and the linkage rod 504 moves up and down through the transmission control of the hinge rod 506.

[0035] Furthermore, a second telescopic spring 510 is fixedly connected to the bottom of the toothed plate 509, and the bottom end of the second telescopic spring 510 is fixedly connected to the power chamber 508. A power gear 517 is rotatably connected inside the moving frame 511, and the power gear 517 meshes with the toothed plate 509. A buffer pad 520 of the buffer toothed plate 509 is fixedly connected to the surface of the sealing shell 501. The second telescopic spring 510 provides a thrust to the toothed plate 509 when the snap-fit ​​plate 502 is closed, thereby improving the closing efficiency of the snap-fit ​​plate 502. The toothed plate 509 moves up and down by rotating the power gear 517.

[0036] Furthermore, the movable frame 511 is internally fixedly connected to a motor 516 that controls the rotation of the power gear 517, and the power compartment 508 is internally fixedly connected to a slide rail 514. The movable frame 511 is slidably connected to the slide rail 514. The rotation of the power gear 517 is controlled by the rotation of the motor 516, and the slide rail 514 limits the movement of the movable frame 511, thereby improving the stability of the sliding of the movable frame 511.

[0037] Furthermore, an iron sheet 518 is fixedly connected to the surface of the movable frame 511, and an electromagnet 519 adapted to the iron sheet 518 is fixedly connected to the surface of the power chamber 508. A third telescopic spring 512 is fixedly connected inside the power chamber 508, and the other end of the third telescopic spring 512 is fixedly connected to the movable frame 511. A reset tube 513 is fixedly connected inside the power chamber 508. The iron sheet 518 is attracted by the electromagnet 519 to fix the movable frame 511, so that the power gear 517 meshes with the gear plate 509.

[0038] Furthermore, when the locking plate 502 needs to be closed, the electromagnet 519 is de-energized, and the moving frame 511 is pulled by the third telescopic spring 512, so that the power gear 517 is disengaged from the toothed plate 509. Through the reset tube 513, a thrust can be provided to the moving frame 511, so that the electromagnet 519 can pick up the iron piece 518.

[0039] like Figure 1 and Figure 4 As shown, the cabinet 1 is equipped with a flame-retardant mechanism 6, which includes an exhaust ring 601 and a gas cylinder 603. When it is necessary to extinguish the fire in the cabinet 1, carbon dioxide gas is released through the gas cylinder 603 and evenly distributed inside the cabinet 1 through the exhaust ring 601, thereby improving the fire extinguishing efficiency of the electrical cabinet.

[0040] Furthermore, the bottom of the cabinet 1 is fixedly connected to a storage compartment 602, and the gas tank 603 is assembled inside the storage compartment 602. The bottom of the gas outlet ring 601 is fixedly connected to a control pipe 604, and the control pipe 604 passes through the cabinet 1 and is fixedly connected to the gas tank 603. The gas tank 603 is stored and fixed through the storage compartment 602, and the gas tank 603 is connected to the gas outlet ring 601 through the control pipe 604. When carbon dioxide gas needs to be released, the gas inside the gas tank 603 is controlled to enter the gas outlet ring 601.

[0041] Furthermore, a solenoid valve is installed inside the control tube 604 to open or close the control tube 604.

[0042] The structural diagrams of the components shown in the attached figures are exemplary. The specific implementation should be adapted and optimized by considering the functional requirements, assembly conditions and process limitations in the actual application scenario, and adjusting the structural parameters, size specifications and connection methods accordingly.

[0043] In use, when the electrical cabinet is overloaded and powered off, the electromagnet 519 is de-energized. The third telescopic spring 512 pulls the moving frame 511, causing the power gear 517 to disengage from the toothed plate 509. The second telescopic spring 510 provides a pushing force to the toothed plate 509, and the first telescopic spring 505 provides a pulling force to the top of the linkage rod 504, causing the linkage rod 504 to quickly move the connecting block 503, which interlocks and closes the snap-fit ​​plates 502, sealing the sealing shell 501. When a fire occurs due to abnormal temperature inside the cabinet 1, the control tube 604 is activated, causing the gas cylinder 603 to release carbon dioxide gas. This gas is evenly distributed inside the cabinet 1 through the gas outlet ring 601, creating an oxygen-deficient environment inside, thereby preventing the occurrence of a fire or controlling its spread, and improving the electrical cabinet's power-off protection capability.

[0044] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model.
