DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-6 This application is described in further detail.

[0021] The embodiment of the present application discloses an electrical cabinet with high safety performance.

[0022] Reference Figure 1-6 The electrical cabinet with high safety performance comprises a cabinet body 1, and a plurality of heat dissipation holes 11 are opened on the side wall of the cabinet body 1.

[0023] A plurality of partitions 12 are arranged in the cabinet 1 along the height direction, and the plurality of partitions 12 divide the space in the cabinet 1 into a plurality of accommodating chambers 13. The heat dissipation holes 11 are connected to the inside of the accommodating chambers 13. The number of partitions 12 is N, and the number of accommodating chambers 13 is N+1. In this embodiment, the number of partitions 12 is two, and the number of accommodating chambers 13 is three. A fire extinguishing mechanism 3 is arranged on the top of each accommodating chamber 13. A temperature sensor is arranged inside the cabinet 1, and the temperature sensor is electrically connected to a buzzer. When the temperature sensor senses that the temperature inside the cabinet 1 exceeds the set value, the buzzer sounds an alarm to remind the staff that the temperature inside the cabinet 1 is abnormal, and to inspect the inside of the cabinet 1 to reduce the possibility of fire.

[0024] The fire extinguishing mechanism 3 includes a containing frame 31, a dry powder bag 32, and a tearing assembly 33 for scratching and tearing the dry powder bag 32. The containing frame 31 is fixedly connected to the inner wall of the cabinet 1, and the dry powder bag 32 is placed in the containing frame 31. A plurality of fire extinguishing ports 311 for powder to pass through are opened on the bottom wall of the containing frame 31, and the tearing assembly 33 is located below the dry powder bag 32.

[0025] Each containing frame 31 is provided with a plurality of fire extinguishing chambers 312 along the length direction, and two adjacent fire extinguishing chambers 312 are separated by a fireproof plate 313 to block the fire and prevent the fire from spreading. Each fire extinguishing chamber 312 corresponds to a group of fire extinguishing mechanisms 3, and the combination of multiple fire extinguishing chambers 312 improves the accuracy of fire extinguishing.

[0026] The tearing assembly 33 includes two sliding plates 331, which move in directions toward or away from each other. A driving assembly 4 for driving the sliding plates 331 to slide is provided in the cabinet 1. A blade 332 is provided on each sliding plate 331, and multiple blades 332 are arranged at intervals along the length direction of the sliding plate 331. A clip 333 is also provided on the two sliding plates 331. The clip 333 is arranged on the side where the blades 332 of the two sliding plates 331 are away from each other, and the clip 333 clamps the bottom bag body of the dry powder bag 32.

[0027] The driving assembly 4 includes a first rack 41, a second rack 42, and a driving gear 43. An installation space for accommodating the driving assembly 4 is provided on the inner wall of the cabinet 1. The driving gear 43 is rotatably arranged in the installation space. The first rack 41 and the second rack 42 slide on both sides of the radial direction of the driving gear 43, respectively. The first rack 41 and the second rack 42 are respectively connected to the two sliding plates 331 of the same group. In this embodiment, the first rack 41 is located below the second rack 42. The first rack 41 is fixedly connected to the right sliding plate 331 through the first connecting rod 411, and the second rack 42 is fixedly connected to the left sliding plate 331 through the second connecting rod 421. The driving gear 43 rotates counterclockwise to control the two sliding plates 331 to move in a direction away from each other.

[0028] A driving shaft 44 is coaxially connected to the driving gear 43, and the driving shaft 44 is fixedly connected to the driving gear 43. The driving shaft 44 is rotatably connected to the installation space. An I-shaped wheel 45 is coaxially connected to the driving shaft 44, and a driving rope 46 is wound around the I-shaped wheel 45. A fire extinguishing groove 14 for the driving rope 46 to extend out is opened on the inner wall of the electrical cabinet, and one end of the driving rope 46 away from the I-shaped wheel 45 is fixedly connected to the inner bottom wall of the fire extinguishing groove 14.

[0029] A coil spring 47 is provided on the drive shaft 44, one end of the coil spring 47 is fixedly connected to the drive shaft 44, and the other end of the coil spring 47 is fixedly connected to the inner wall of the installation space. The drive rope 46 applies a force to the drive shaft 44 to rotate the drive shaft 44 clockwise, and the coil spring 47 is compressed at this time.

[0030] When a fire occurs, the flame burns the drive rope 46, and the coil spring 47 loses its restraint and returns to its original state, causing the drive shaft 44 to rotate and the sliding plate 331 to slide in directions away from each other. As the sliding plate 331 moves, the blade 332 cuts the dry powder bag 32 and the clamp 333 clamps the bag body of the dry powder bag 32 to pull the dry powder bag 32 open, thereby quickly pouring out the dry powder in the dry powder bag 32 and extinguishing the fire. The fire can be extinguished quickly and timely, which improves the safety of the electrical cabinet and avoids causing a fire.

[0031] The top surface of the sliding plate 331 is provided with a receiving groove 5 for receiving the blade 332 . The blade 332 is connected to the inner wall of the receiving groove 5 in a lifting manner. The blade 332 can be lowered to be completely located in the receiving groove 5 , and the blade 332 can also be raised to extend out of the receiving groove 5 .

[0032] A synchronous plate 6 is rotatably arranged in the receiving groove 5, and a lifting groove 51 for the synchronous plate 6 to be lifted and lowered is arranged on the sliding plate 331. The synchronous plate 6 is fixedly connected to all the blades 332 on one sliding plate 331 at the same time. A first inclined surface 61 is arranged on the bottom surface of the end of the synchronous plate 6 that is away from each other. A matching plate 7 is fixedly arranged on the inner bottom wall of the receiving frame 31, and a second inclined surface 71 is arranged on the top surface of the matching plate 7 close to the end of the synchronous plate 6. A giving way groove 3311 for the matching plate 7 to give way is provided on the sliding plate 331. Multiple matching plates 7 are arranged at intervals along the length direction of the sliding plate 331 to improve the force stability of the sliding plate 331.

[0033] When the sliding plate 331 moves in a direction away from each other, the first inclined surface 61 of the synchronous plate 6 cooperates with the second inclined surface 71 of the matching plate 7, so that the sliding plate 331 gradually moves to the top of the matching plate 7, so that the top of the blade 332 extends out of the receiving groove 5. When there is no fire, the blade 332 is completely located in the receiving groove 5 to prevent the blade 332 from accidentally damaging the dry powder bag 32. After the fire occurs, as the sliding plate 331 moves, the blade 332 extends out of the receiving groove 5 to cut the dry powder bag 32.

[0034] The implementation principle of an electrical cabinet with high safety performance in the embodiment of the present application is as follows: When a fire occurs, the flame burns off the drive rope 46, and the coil spring 47 loses its constraint and returns to its original state, causing the drive shaft 44 to rotate, causing the sliding plate 331 to slide in a direction away from each other. As the sliding plate 331 moves, the sliding plate 331 gradually moves to the top of the matching plate 7, so that the top of the blade 332 extends out of the accommodating groove 5, and the blade 332 cuts the dry powder bag 32, and the clip 333 clamps the bag body of the dry powder bag 32 to pull the dry powder bag 32 open, thereby quickly pouring out the dry powder in the dry powder bag 32 and extinguishing the fire. The fire can be extinguished quickly and timely, which improves the safety of the electrical cabinet and avoids causing a fire.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
