DETAILED DESCRIPTION

[0021] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate several embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] A fireproof electrical cabinet, such as Figure 1-Figure 5As shown, it includes a cabinet body 1 and a cabinet door 2 rotatably connected to the cabinet body 1, a fire detector 4, an electrical component 5 and a fire extinguishing assembly 7 are arranged in the cabinet body 1, a plurality of ventilation holes 11 are opened on the side of the cabinet body 1, and a driving assembly 3 for driving the cabinet door 2 to close is provided on the cabinet body 1, the driving assembly 3 includes a first bracket 31 arranged on the cabinet body 1 and a first driving member arranged on the first bracket 31, a driving gear 33 is provided on the driving shaft of the first driving member, and a driven gear 34 is rotatably provided on the rotating shaft of the cabinet door 2, the driven gear 34 and the driving gear 33 are engaged with each other, and a torsion spring 35 is provided between the driven gear 34 and the rotating shaft of the cabinet door 2, when the fire detector 4 detects a fire, the trigger system will trigger the first driving member and the fire extinguishing assembly 7 to operate, and the operation of the first driving member will drive the cabinet door 2 to close through the cooperation of the driving gear 33 and the driven gear 34, and the first driving member is a motor 32.

[0025] Among them, the fire detector 4 is used to detect whether there is a fire in the electrical cabinet. The fire extinguishing component 7 is electrically connected to the fire detector 4. When the fire detector 4 detects a fire, it will control the fire extinguishing component 7 to operate immediately to extinguish the fire. When a fire occurs, the driving component 3 is used to drive the opened cabinet door 2 to close;

[0026] Specifically, when a fire occurs in the electrical cabinet, the fire detector 4 will first sense it, and the fire detector 4 will activate the trigger system. The trigger system will control the motor 32 and the fire extinguishing component 7 to operate. The fire extinguishing component 7 will extinguish the fire in the electrical cabinet. The operation of the motor 32 will drive its own drive shaft to rotate forward for one circle. The forward rotation of the drive shaft will drive the driving gear 33 to rotate forward. The forward rotation of the driving gear 33 will drive the driven gear 34 to rotate forward. If the cabinet door 2 is open, the rotation of the driven gear 34 will drive the torsion spring 35 to rotate. The rotation of the torsion spring 35 will drive the cabinet door 2 to move closer to the cabinet body 1. Close. If the cabinet door 2 itself is in a closed state, when the driven gear 34 rotates, the cabinet door 2 cannot rotate, so the torsion spring 35 will deform. When the motor 32 is not powered, that is, the fire detector 4 does not detect a fire or the motor 32 drives its own drive shaft to rotate one circle, the torsion spring 35 will reset. The reset of the torsion spring 35 will drive the driven gear 34 to idle on the rotating shaft of the cabinet door 2. The cabinet door 2 will not be opened due to the reset of the torsion spring 35. When people open and close the cabinet door 2 normally, since the motor 32 is not powered, it does not affect people's normal opening and closing of the cabinet door 2.

[0027] To sum up, by setting up a fire detector 4 to sense whether a fire has occurred, the motor 32 is used to drive the cabinet door 2 to close in time at the first time of the fire to prevent the cabinet door 2 from opening and causing the fire to spread. At the same time, through the setting of the driving gear 33, the driven gear 34 and the torsion spring 35, regardless of whether the cabinet door 2 is in a closed or open state, the driving component 3 can still operate stably and does not affect the normal opening and closing operations of the cabinet door 2. In addition, by setting up the fire extinguishing component 7 and the fire detector 4 to cooperate with each other, the fire can be fully extinguished at the first time of the fire to prevent the fire from spreading.

[0028] like Figure 4 As shown, the cabinet body 1 is provided with a closing component 6 for blocking the ventilation hole 11, and the closing component 6 includes a second bracket 61 provided on the cabinet body 1 and a second driving member provided on the second bracket 61, and a connecting block 64 is provided on the output shaft of the second driving member. The cabinet body 1 is provided with a sliding sleeve 63, and a blocking frame 65 for blocking the ventilation hole 11 is slidingly provided in the sliding sleeve 63. The blocking frame 65 is connected to the connecting block 64, and the second driving member is an electric push rod 62.

[0029] In order to achieve the heat dissipation effect of the electrical components 5, ventilation holes 11 are usually provided on the cabinet 1. When the electrical cabinet catches fire, sparks may splash out from the ventilation holes 11. Therefore, when the fire occurs, the fire detector 4 senses it and controls the electric push rod 62 to operate through the trigger system. The output shaft of the electric push rod 62 will extend when the output shaft extends, and the connecting block 64 will move downward when the connecting block 64 moves downward, which will drive the blocking frame 65 to move downward. The blocking frame 65 moves downward to block the ventilation holes 11, thereby effectively preventing sparks from splashing from the ventilation holes 11 and causing the fire to spread. When the fire detector 4 senses that there is no fire, it will control the output shaft of the electric push rod 62 to retract through the trigger system, thereby driving the blocking frame 65 to no longer block the ventilation holes 11, so that the electrical cabinet can achieve good ventilation effect.

[0030] like Figure 5 As shown, the fire extinguishing assembly 7 includes a third driving member arranged in the cabinet 1, and a fire extinguisher 72 for extinguishing a fire is provided on the output block of the third driving member. The third driving member drives the fire extinguisher 72 to move, and the third driving member is an electric slide rail 71.

[0031] When the fire detector 4 senses a fire, the trigger system will control the fire extinguisher 72 and the electric slide 71 to start. The output block of the electric slide 71 will drive the fire extinguisher 72 to operate back and forth in the vertical direction, thereby extinguishing all the fire in the electrical cabinet. Therefore, by setting the fire extinguisher 72 to be movable, the fire in the electrical cabinet can be completely extinguished. When the fire detector 4 does not sense a fire, the fire extinguisher 72 and the electric slide 71 will also be closed.

[0032] The fire extinguisher 72 is arranged in parallel with the electrical component 5 .

[0033] Among them, by arranging the fire extinguisher 72 in parallel with the electrical component 5, the fire in the electrical cabinet can be extinguished more comprehensively.

[0034] A sliding rod 73 is provided in the cabinet 1 , and one end of the fire extinguisher 72 is slidably connected to the sliding rod 73 .

[0035] Among them, through the setting of the sliding rod 73, the fire extinguisher 72 will be more stable when it reciprocates in the vertical direction.

[0036] The fire extinguisher 72 is a dry powder fire extinguisher 72 or a carbon dioxide fire extinguisher 72 .

[0037] A plurality of through holes are provided on one side wall of the cabinet body 1 , and corresponding through holes are also provided on the side wall on the opposite side, and the through holes on both sides are aligned.

[0038] Among them, by aligning the through holes on both sides, the air circulation in the electrical cabinet can be accelerated, thereby achieving a better heat dissipation effect in the cabinet body 1.
