Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses an automatic open extinguishing device. Referring to fig. 1, an automatic opening fire extinguishing apparatus includes a shower pipe 1 and a spray sheet 2 fixed to the bottom of the shower pipe 1. The bottom of the spray pipe 1 is fixed with a connecting shaft 21, and the bottom end of the connecting shaft 21 is fixedly connected with the disk-shaped spray sheet 2. The spraying piece 2 is evenly distributed with a plurality of spraying teeth 22 along the circumference. A water inlet pipe 23 is fixed at the top end of the spray pipe 1. The outer peripheral surface of the spray pipe 1 is uniformly provided with a plurality of first nozzles 24 along the circumferential direction.

The shower pipe 1 is installed on the roof of the house. After entering the spray pipe 1 through the water inlet pipe 23, the water flow is sprayed out from a first spray opening 24 on the spray pipe 1. The sprayed water flow firstly collides with the spraying sheet 2 and is poured from the periphery of the spraying sheet 2 to the periphery. The spray teeth 22 on the peripheral side of the spray plate 2 allow the water stream to form a plume during pouring.

Referring to fig. 2 and 3, a plurality of groups of sealing components 3 for preventing water flow from flowing out of the shower pipe 1 are arranged in the pipe wall of the shower pipe 1. The sealing assembly 3 comprises a cover plate 31 which is arranged in the spraying pipe 1 in a sliding manner along the circumferential direction of the spraying pipe 1 and a baffle 32 which is arranged in the spraying pipe 1 in a sliding manner along the vertical direction. The cover plate 31 is provided with a second nozzle 14 which can be aligned with the first nozzle 24. An arc-shaped sliding groove I33 is formed in the pipe wall of the spraying pipe 1, and the spraying pipe 1 is connected with the cover plate 31 in a sliding mode along the circumferential direction of the spraying pipe 1 through the sliding groove I33. A second sliding groove 34 which is perpendicular to the first sliding groove 33 is formed in the pipe wall of the spraying pipe 1, and the spraying pipe 1 is connected with the blocking piece 32 in a sliding mode through the second sliding groove 34 in the vertical direction.

Referring to fig. 3 and 4, the sidewall of the blocking plate 32 is opened with a through hole 35 for the cover plate 31 to pass through. The top surface of the through hole 35 is fixed with a plug piece 36, and the top surface of the cover plate 31 is provided with a plug groove which can be plugged with the plug piece 36. The bottom of the second sliding groove 34 is fixed with a fireproof expansion rubber block 11, and the bottom end of the blocking piece 32 is abutted to the fireproof expansion rubber block 11. The material of the fireproof expansion rubber block 11 is ethylene propylene diene monomer. The outer arc surface and the inner arc surface of the cover plate 31 are respectively coated with a waterproof coating, and the waterproof coating is made of polyurethane.

Before the cover plate 31 moves, the second nozzle 14 and the first nozzle 24 are in a dislocation state, and water flow is accumulated in the spray pipe 1. The insertion piece 36 on the blocking piece 32 is in an insertion state with the insertion groove of the cover plate 31, so as to provide a limiting function for the cover plate 31 and prevent the cover plate 31 from moving. After the blocking piece 32 moves upwards, the inserting piece 36 on the blocking piece 32 is separated from the inserting groove on the cover plate 31, and the cover plate 31 loses the limiting function.

Referring to fig. 2 and 3, a first spring 25 is fixed on the top of the blocking piece 32, and the top end of the first spring 25 is fixedly connected with the top wall of the second sliding groove 34. The cover plate 31 has guide pieces 26 fixed to its top and bottom surfaces, respectively. The top surface and the bottom surface of the first sliding groove 33 are respectively provided with a guide groove 27, the guide piece 26 is connected with the spray pipe 1 in a sliding mode along the circumferential direction of the spray pipe 1 through the guide groove 27, one side, close to the blocking piece 32, of the guide piece 26 is fixedly provided with a second spring 15, and one end, far away from the guide piece 26, of the second spring 15 is fixedly connected with the inner wall, close to the blocking piece 32, of the guide groove 27.

Referring to fig. 1, a guide shaft 12 is fixed at the top of the blocking piece 32, a guide hole 13 is formed in the top surface of the second sliding chute 34, and the guide shaft 12 is connected with the spray pipe 1 in a sliding manner vertically through the guide hole 13.

The implementation principle of the automatic fire extinguishing device is that:

after entering the shower pipe 1 through the water inlet pipe 23, the water flow is blocked by the cover plate 31. When a fire disaster occurs indoors and the air temperature rises rapidly, the volume of the fireproof expansion rubber block 11 is increased, the blocking piece 32 is pushed to move upwards, the insertion piece 36 on the blocking piece 32 is separated from the insertion groove on the cover plate 31, the cover plate 31 loses the limiting effect, and the cover plate moves under the action of the second spring 15. After the cover plate 31 moves, the second nozzle 14 is aligned with the first nozzle 24, and water flow is sprayed out from the first nozzle 24 on the spray pipe 1. The sprayed water flow firstly collides with the spraying sheet 2 and is poured from the periphery of the spraying sheet 2 to the periphery. The spray teeth 22 on the peripheral side of the spray plate 2 allow the water stream to form a plume during pouring.

The above are preferred embodiments of the present application, and the scope of protection of the present application is not limited thereto, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
