[0013] II. This utility model, by setting up a spraying device, allows the fire extinguisher to deliver extinguishing gas to the main pipe through the connecting pipe when the fire extinguisher is working. The extinguishing gas is then sprayed through the nozzles on the branch pipes. Under the action of the spraying device, the extinguishing gas inside the fire extinguisher can be evenly and comprehensively sprayed into the cabinet to extinguish the fire. Since the spraying device is shaft-connected to the inside of the cabinet, the spraying device can be flipped outward from inside the cabinet, which facilitates the installation and maintenance of electrical components installed inside the cabinet without creating obstruction. When the spraying device is flipped inward, the fastener and the fastening hole work together to connect and fix the fastening plate to the overlapping plate, achieving simple fixation of the spraying device inside the cabinet.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-8 This utility model provides a technical solution: a power distribution cabinet with rapid automatic fire extinguishing function, comprising: a placement frame 1 and a cabinet body 3. The placement frame 1 is fixed to the left end of the cabinet body 3. A fire extinguisher 8 is fixed inside the placement frame 1. A spraying device 4 is provided inside the cabinet body 3. The spraying device 4 is axially connected to the inner wall of the left end of the cabinet body 3. A connecting pipe 7 connects the fire extinguisher 8 and the spraying device 4. The connecting pipe 7 passes through the inside of the left end of the cabinet body 3. The fire extinguisher 8 delivers fire extinguishing gas to the spraying device 4 through the connecting pipe 7. The spraying device 4 sprays the fire extinguishing gas into the inside of the cabinet body 3 to extinguish the fire. A cavity 6 is opened inside the upper end of the cabinet body 3. Gas outlet pipes 2 are fixed to the outer walls of the cabinet body 3 on both sides of the cavity 6. A smoke alarm 5 for smoke warning is fixedly fitted at the lower end of the cavity 6.

[0027] In order to extinguish the fire evenly and comprehensively by spraying the extinguishing gas inside the fire extinguisher 8 into the cabinet 3, the spraying device 4 includes a cover plate 41, a branch pipe 42 and a main pipe 43. The branch pipe 42 is fixedly connected between the cover plate 41 and the main pipe 43. The outer wall of the rear end of the branch pipe 42 is evenly provided with spray holes 421. The branch pipe 42 and the main pipe 43 are in a connected state. The fire extinguisher 8 delivers the extinguishing gas to the main pipe 43 through the connecting pipe 7 and sprays it through the spray holes 421 on the branch pipe 42.

[0028] To detect smoke inside cabinet 3 and activate fire extinguisher 8, smoke detector 5 includes a suction fan 51 and a housing 53. The suction fan 51 is fixed to the upper end of housing 53, and the suction fan 51 and housing 53 are in communication. A mesh plate 52 is provided at the upper end of the suction fan 51. A smoke inlet 55 is provided inside the outer wall of housing 53. A smoke sensor 56 is provided inside housing 53. A horn 54 is provided on the inner side wall of housing 53. A control panel is provided on the inner wall of housing 53 opposite to the horn 54. When the controller 57 and the suction fan 51 are working, they can extract the gas inside the cabinet 3 to achieve ventilation and air exchange inside the cabinet 3. In addition, when the suction fan 51 is sucking air, it can accelerate the airflow inside the cabinet 3, so that the smoke sensor 56 can quickly detect the smoke. The horn 54 and the fire extinguisher 8 are both electrically connected to the controller 57. After the smoke sensor 56 detects the smoke, the controller 57 controls the horn 54 to sound an alarm and activates the fire extinguisher 8, so that the fire extinguisher 8 can extinguish the fire through the spray device 4.

[0029] In order for the spraying device 4 to be flipped and fixed inside the cabinet 3, a fastener 411 is fixed to the outer wall of the rear end of the buckle plate 41, and an overlapping plate 9 that cooperates with the buckle plate 41 is fixed to the inner side wall of the cabinet 3. The overlapping plate 9 has a fastening hole 91 that cooperates with the fastener 411. Under the combined action of the fastener 411 and the fastening hole 91, the buckle plate 41 can be connected and fixed to the overlapping plate 9.

[0030] The vent pipe 2 has a right-angle structure, and the cavity 6 is connected to the outside through the vent pipe 2, which enables ventilation inside the cabinet 3. Because the vent pipe 2 has a right-angle structure, it ensures that rainwater will not enter the cabinet 3.

[0031] To facilitate easy fixing or separation of the buckle plate 41 and the overlapping plate 9, the fastener 411 consists of a horizontal bar, a vertical bar, a pivot, and a torsion spring. The vertical bar is connected to the horizontal bar through the pivot. The vertical bar and the horizontal bar are perpendicular in their natural state. The torsion spring is symmetrically fixed between the vertical bar and the horizontal bar. When the buckle plate 41 is pushed or pulled, the vertical bar can swing under the action of the torsion spring, so that it can shuttle inside the buckle hole 91, realizing the connection and separation of the buckle plate 41 and the overlapping plate 9.

[0032] The working principle and usage process of this utility model are as follows: After the utility model is installed, when it is used for operation, the air inside the cabinet 3 can be dispersed to the outside through the cavity 6 and the exhaust pipe 2 during the operation of the suction fan 51. This achieves ventilation and heat dissipation inside the cabinet 3. Furthermore, since the exhaust pipe 2 has a right-angle structure, it ensures that rainwater will not enter the cabinet 3. When the suction fan 51 is suctioning, it can accelerate the airflow inside the cabinet 3 and quickly gather the gas into the smoke detector 5, so that the smoke sensor 56 can quickly detect the smoke. The horn 54 and the fire extinguisher 8 are both electrically connected to the controller 57. After the smoke sensor 56 detects the smoke, the controller 57 controls the horn 54 to sound an alarm and activates the fire extinguisher 8. The fire extinguisher 8 then delivers the extinguishing gas to the main pipe 43 through the connecting pipe 7, and then sprays it through the nozzle 421 on the branch pipe 42, so that the extinguishing gas inside the fire extinguisher 8 is evenly and comprehensively sprayed into the cabinet 3 to extinguish the fire.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
