By installing the shell on the passage of the power distribution room, when a fire occurs, the cylinder drives the abutment plate away from the bottom plate, so that the curtain can fall and close the passage to isolate the fire area and prevent the spread of fire and smoke. At the same time, the overall weight of the curtain is relatively light, making it easier to enter the fire area from the outside to extinguish the fire, and it does not affect the escape of the staff.

[0016] 2. By moving the push plate away from the notch of the container, the container can roll down the inclined platform, allowing the water inside the container to enter the curtain body through the through hole, thereby improving the fire resistance of the curtain body. At the same time, magnetic strips are set on both sides of the curtain body, so that multiple curtains can cooperate with each other to seal the channel, greatly improving the practicality of the curtain body in fire prevention.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0026] In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] like Figures 1 to 7 As shown, a fireproof device for a power distribution room includes a housing 1 and a base plate 11 rotatably disposed at the bottom of the housing 1. The base plate 11 is hinged to the housing 1 and can rotatably open or close the interior of the housing 1. The housing 1 can be installed on the passageway of the power distribution room. Specifically, an mounting plate 18 is fixed to the upper end of the housing 1. The housing 1 can be installed on the door frame 5 of the passageway of the power distribution room through the mounting plate 18 to avoid interference with the normal use of the power distribution room in this embodiment.

[0028] The housing 1 is provided with a partition 12 that divides its interior into an upper cavity 13 and a lower cavity 14. A curtain 2 located in the lower cavity 14 is installed on the partition 12. The curtain 2 abuts against the bottom plate 11. Specifically, the curtain 2 includes fireproof cloth 21 and glass wool 23. The fireproof cloth 21 has an inner cavity 22. The glass wool 23 is located in the inner cavity 22. That is, the fireproof cloth 21 is provided on the outside of the glass wool 23. The upper end of the partition 12 has an opening, and the upper end of the fireproof cloth 21 is fixed to the partition 12.

[0029] A cylinder 4 is installed in the upper cavity 13. The output end of the cylinder 4 is connected to an abutment plate 42 that abuts against the bottom plate 11. When a fire occurs, the cylinder 4 drives the abutment plate 42 to move away from the bottom plate 11, that is, the bottom plate 11 can rotate downward, so that the curtain 2 can fall and close the passage to isolate the fire area and prevent the spread of fire and smoke. At the same time, the curtain 2 is made of fireproof cloth 21 and glass wool 23, which makes the overall weight of the curtain 2 relatively light, so it will not interfere with the entry and exit of firefighters to extinguish the fire. That is, it is easier to enter the fire area from the outside to extinguish the fire, and it does not affect the escape of the staff.

[0030] The partition 12 has a through hole 15 that connects the inner cavity 22 and the upper cavity 13. The upper cavity 13 is provided with a water-filled container 3. The container 3 is set on an inclined platform 17. The upper end of the container 3 has a notch 31, and at this time, the notch 31 is set upward to prevent the water in the container 3 from pouring out from the notch 31. Furthermore, the output end of the cylinder 4 is connected to a push plate 41 that abuts against the notch 31. The push plate 41 is partially inserted into the notch 31 to limit the position of the container 3.

[0031] Furthermore, the inclined platform 17 is provided with a horizontally arranged placement platform 171, and the container 3 is placed on the placement platform 171, thereby enabling the container 3 to be more stably placed on the inclined platform 17.

[0032] Furthermore, a counterweight 32 is fixed to the side of the notch 31. When the cylinder 4 is activated, the push plate 41 moves away from the notch 31 of the container 3, allowing the container 3 to roll down the inclined platform 17 under the action of gravity. Since the counterweight 32 is provided on the side of the notch 31, after the container 3 rolls down, the notch 31 can face downwards. Thus, the water in the container 3 can enter the inner cavity 22 of the curtain 2 through the through hole 15. By injecting water into the curtain 2, the fire resistance of the curtain 2 can be improved.

[0033] To further improve the fire resistance of the curtain 2 and prevent it from being damaged by intense fire, thus ensuring the reliability of the curtain 2 in isolating fire and smoke, a heat dissipation plate 16 is provided in the upper cavity 13. The heat dissipation plate 16 is spaced above the through hole 15. When the inner cavity 22 is filled with water in the container 3, some of the water submerges the lower part of the heat dissipation plate 16. When the temperature of the curtain 2 rises due to fire isolation, the water can act as a medium to conduct heat to the heat dissipation plate 16 for heat dissipation, thereby further improving the fire resistance of the curtain 2 and ensuring the reliability of the curtain 2 in use.

[0034] Flexible magnetic strips 24 are provided on both sides of the curtain 2, so that multiple curtains 2 can cooperate with each other to close the passage, which greatly improves the fireproof practicality of the curtain 2. Furthermore, iron strips 51 that cooperate with the magnetic strips 24 are provided on both sides of the door frame 5. When the curtain 2 falls, the magnetic strips 24 on the curtain 2 can be magnetically attracted to the iron strips 51, so that the curtain 2 can better close the passage.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
