Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting facilities, in particular to a drip-proof fire-fighting electrical fire-extinguishing device. Background Art

[0002] Fire sprinkler heads are used in fire sprinkler systems as automatic fire extinguishing devices. Generally, fire sprinkler heads are installed on walls or ceilings and connected to pressurized water network pipes, or individual sprinkler heads are installed along the pipes to protect the area below them. In the event of a fire, the heat-sensitive glass tube is affected by the high temperature and the internal liquid begins to expand. When the expansion limit is exceeded, the liquid will squeeze the glass ball and the water in the water pipe will flow out to extinguish the fire.

[0003] The existing sprinkler head is blocked by a sealing plug, and the bottom of the sealing plug is supported by a thermosensitive glass tube. After long-term use, the sealing plug will inevitably age or be corroded by air and water, which will cause leakage, causing water to seep downward from the sprinkler head, which will interfere with normal life in the room. To this end, we provide a drip-proof fire electrical fire extinguishing device. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-5 As shown, the utility model provides a technical solution: a drip-proof fire-fighting electrical fire-extinguishing device, comprising a fixed sleeve 1, a slot 11 is provided at the bottom of the fixed sleeve 1, a water inlet pipe 2 is penetrated and connected to the top of the fixed sleeve 1, a nozzle 3 is penetrated and connected to the bottom of the fixed sleeve 1, the water inlet pipe 2 is connected to the external high-pressure water network pipeline, and the fire-fighting water in the high-pressure water network can be injected into the nozzle 3 through the water inlet pipe 2.

[0025] Among them, the outer ring of the nozzle 3 is provided with a support plate 4, a sealing cover 5 is provided in the middle of the bottom of the support plate 4, the top of the sealing cover 5 is open, a support rod 51 is provided at the bottom of the inner wall of the sealing cover 5, and a sealing plug 52 is provided on the top of the support rod 51. The sealing plug 52 is made of materials such as rubber or silicone with good sealing properties. The top of the sealing plug 52 is inserted into the bottom of the inner cavity of the nozzle 3. During installation, the nozzle 3 can be blocked by inserting the sealing plug 52 into the nozzle 3 to prevent it from leaking downward.

[0026] Furthermore, a sealing ring 53 is provided on the top of the sealing cover 5. The sealing ring 53 is made of materials such as rubber or silicone with good sealing properties. The sealing ring 53 is inserted into the inner cavity of the slot 11. An airbag 54 is provided on the inner ring of the sealing ring 53. In the initial state, the airbag 54 is deflated. An inflation channel 55 is opened on the left side of the sealing cover 5. The air outlet of the inflation channel 55 passes through the bottom of the sealing ring 53 and is connected to the inner cavity of the airbag 54. The air inlet of the inflation channel 55 is provided with a plug 9.

[0027] During specific use, during installation, by inserting the sealing ring 53 into the slot 11, the sealing cover 5 can enclose the entire nozzle 3. Once the sealing plug 52 leaks due to aging or corrosion by air and water, the sealing cover 5 can catch the water droplets to prevent them from dripping onto the ground. At the same time, the plug block 9 can be pulled out of the inflation channel 55, and then air is filled into the air bag 54 through the inflation channel 55 to make the air bag 54 swell. Through the double sealing of the sealing ring 53 and the air bag 54, the sealing cover 5 can be in a completely sealed state, which can prevent the water in the sealing cover 5 from overflowing and flowing to the ground, so as to ensure normal life in the room. After inflation, the plug block 9 can be reinserted into the inflation channel 55 to seal it.

[0028] Among them, a card hole 56 is opened at the bottom of the sealing cover 5, a bracket 6 is connected between the left and right sides of the bottom of the support plate 4, a card slot 61 is set at the bottom of the inner wall of the bracket 6, a thermosensitive glass tube 7 is connected between the bottom of the sealing cover 5 and the bottom of the inner wall of the bracket 6, and a card rod 71 is set at the top and bottom of the thermosensitive glass tube 7. The card rod 71 located at the top is inserted into the inner cavity of the card hole 56, and the card rod 71 located at the bottom is inserted into the inner cavity of the card slot 61. During installation, the upper card rod 71 is inserted into the card hole 56, and the lower card rod 71 is inserted into the card slot 61 at the same time, so that the thermosensitive glass tube 7 is placed between the sealing cover 5 and the bottom of the inner wall of the bracket 6. The thermosensitive glass tube 7 can push the sealing cover 5 upward to be fixed to the bottom of the support plate 4.

[0029] Furthermore, a splash plate 8 is provided at the bottom of the bracket 6 . The splash plate 8 is fixed to the bottom of the bracket 6 through a support bar 81 . A plurality of notches 82 are evenly formed on the outer circle of the splash plate 8 .

[0030] During specific use, the thermosensitive glass tube 7 is filled with a thermosensitive liquid. When a fire occurs indoors, the liquid in the thermosensitive glass tube 7 begins to expand due to the high temperature. When the set expansion limit is exceeded, the liquid will expand the thermosensitive glass tube 7. At this time, the resistance force on the sealing cover 5 disappears, and the fire-fighting water in the nozzle 3 can flush out the sealing plug 52. At the same time, the sealing cover 5 falls downward, and then the fire-fighting water is sprayed downward onto the splash plate 8. The notch 82 can cause the water to splash everywhere to extinguish the fire indoors.
