Description

Technical Field

[0001] The utility model relates to the technical field of fire sprinklers, in particular to a fire sprinkler dispersion large-range adapter. Background Art

[0002] Fire sprinkler: A sprinkler that starts automatically within a predetermined temperature range under the action of heat, or is started by a control device according to a fire signal, and sprays water for fire extinguishing according to the designed sprinkling shape and flow rate. It is a part of the sprinkler system.

[0003] When a fire breaks out inside a building, it is necessary to control or extinguish the fire by spraying water through a fire sprinkler.

[0004] However, when the existing fire sprinkler adapter sprays water, it can only spray a fixed area, and the existing fire sprinkler adapter cannot increase the spraying range when spraying water, thus reducing the fire extinguishing efficiency.

[0005] Moreover, when the existing fire sprinkler adapter sprays water, when the water pressure is too high, some water will directly splash to the side, causing the water to fall vertically on the ground and unable to be diffused through the splash plate, resulting in a reduction in the fire extinguishing effect. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a fire sprinkler dispersion large-range adapter to solve the problems raised in the above background art.

[0007] To solve the above technical problems, the utility model provides the following technical solution: A fire sprinkler dispersion large-range adapter, comprising:

[0008] A main body;

[0009] A diffusion block located at the bottom of the main body, and the diffusion block is used to expand the spraying area of water;

[0010] A support rod is arranged at the bottom of the main body. The top of the support rod is connected to the bottom of the main body by welding. The bottom of the support rod is connected to the outer wall of the column by a fastener. A rotating column is arranged inside the column. The rotating column is connected to a spiral plate by a fastener. The bottom of the rotating column is connected to a diversion plate by a fastener. The outside of the diversion plate is connected to the diffusion block by a fastener. An expansion ring is arranged on the outer wall of the main body.

[0011] Preferably, one end of a fixing rod is connected to the inside of the support rod by a fastener. The end of the fixing rod away from the support rod is connected to one side of an adapter block by a fastener. The top of the column is connected to a flared block by welding.

[0012] Preferably, the bottom of the connecting block is connected to one end of the rotating column away from the flow guiding disc through a rotating shaft, and the bottom of the glass column is provided at the top of the connecting block.

[0013] Preferably, the top of the glass column is connected to the bottom end of the plug in an embedded form, the outer wall of the plug is connected to the inside of the main body through a fastener, and a through hole is provided on the plug.

[0014] Preferably, a baffle is provided on the top of the flow guiding disc, the baffle is connected to the flow guiding disc by welding, and one end of the baffle is connected to the diffusion block by welding.

[0015] Preferably, the telescopic ring is connected to the outer wall of the main body in a sliding form, the top of the telescopic ring is connected to the bottom end of the elastic member through a fastener, and the top end of the elastic member is connected to the main body through a fastener.

[0016] Preferably, the inner wall of the telescopic ring is connected to the bevel plate through a fastener, and the diffusion blocks are evenly distributed on the flow guiding disc.

[0017] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0018] First, by setting the spiral disc and the diffusion block, the present utility model can increase the dispersion range of the water sprayed by the fire sprinkler. When a fire occurs inside a building, due to the high temperature, the glass column breaks, and the water inside the pipeline is sprayed to the outside through the plug. The water enters the inside of the column through the flared block, the water entering the inside of the column impacts the spiral piece, and the spiral piece is rotated by the water impact through the rotating column. The rotating column drives the flow guiding disc to rotate. After the water falls on the flow guiding disc, it is guided to the inside of the diffusion block through the baffle on the flow guiding disc. The flow guiding disc drives the diffusion block to rotate, and the diffusion block swings the water inside it to a farther position, so that the adapter of the fire sprinkler can spray water over a large range, effectively improving the fire extinguishing efficiency.

[0019] Second, by setting the telescopic ring and the bevel plate, the present utility model can prevent water from splashing to the outside. When the water sprayed by the main body is large, part of the water splashes to one side through the nozzle. The water impacts on the bevel plate, and through the impact force of the water, the bevel plate drives the telescopic ring to move downward to limit the splashed water, preventing the water from dripping vertically onto the ground. When not in use, the elastic member pulls the telescopic ring to always be located outside the main body, preventing the telescopic ring from covering the glass column and causing the glass column to be unable to effectively sense the external temperature, reflecting the practicability of this device.

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-5 , a fire sprinkler dispersion large-range adapter, comprising:

[0028] Main body 1;

[0029] The diffusion block 7 located at the bottom of the main body 1, and the diffusion block 7 is used to expand the spraying area of water;

[0030] At the bottom of the main body 1, there is a support rod 2. The top of the support rod 2 is connected to the bottom of the main body 1 by welding. The bottom of the support rod 2 is connected to the outer wall of the column 5 through fasteners. Inside the column 5, there is a rotating column 10. The rotating column 10 is connected to the spiral blade 9 through fasteners. The bottom of the rotating column 10 is connected to the diversion plate 4 through fasteners. The outside of the diversion plate 4 is connected to the diffusion block 7 through fasteners. An expansion ring 12 is provided on the outer wall of the main body 1. When a fire breaks out inside a building, due to the excessive temperature, the glass column 3 breaks. The water inside the pipeline is sprayed to the outside through the plug 15. The water enters the inside of the column 5 through the flared block 14. The water entering the inside of the column 5 impacts the spiral blade 9. The spiral blade 9 is impacted by the water and rotates through the rotating column 10. The rotating column 10 drives the diversion plate 4 to rotate. After the water falls on the diversion plate 4, it is diverted to the inside of the diffusion block 7 through the baffle 6 on the diversion plate 4. The diversion plate drives the diffusion block 7 to rotate. The diffusion block 7 swings the water inside it to a farther position, so that the fire sprinkler adapter can spray water over a large range, effectively improving the fire extinguishing efficiency.

[0031] Specifically, one end of the fixing rod 16 is connected to the inside of the support rod 2 through fasteners. The end of the fixing rod 16 away from the support rod 2 is connected to one side of the connection block 8 through fasteners. The top of the column 5 is connected to the flared block 14 by welding.

[0032] Through the above technical solution, the fixing rod 16 is used to support the connection block 8, so that the connection block 8 can support the glass column 3 and the rotating column 10. The flared block 14 is used to increase the water flowing into the inside of the column 5.

[0033] Specifically, the bottom of the connection block 8 is connected to one end of the rotating column 10 away from the diversion plate 4 through a rotating shaft. The bottom of the glass column 3 is provided at the top of the connection block 8.

[0034] Through the above technical solution, the connection block 8 is used to support the rotating column 10 and the spiral blade 9, so that the spiral blade 9 is in a suspended state inside the column 5, which is convenient for rotation by the impact of water flow.

[0035] Specifically, the top of the glass column 3 is connected to the bottom end of the plug 15 by embedding. The outer wall of the plug 15 is connected to the inside of the main body 1 through fasteners. A through hole is provided on the plug 15.

[0036] Through the above technical solution, a special liquid is filled inside the glass column 3. When it encounters a certain temperature, the glass column 3 will break due to the liquid.

[0037] Specifically, a baffle 6 is provided on the top of the diversion plate 4. The baffle 6 is connected to the diversion plate 4 by welding. One end of the baffle 6 is connected to the diffusion block 7 by welding.

[0038] Through the above technical solution, the baffle 6 is used to divert the water falling on the diversion disc 4 so that the water can flow into the inside of the diffusion block 7, and then when the turntable rotates, it will drive the water inside the diffusion block 7 to be thrown to a farther position.

[0039] Specifically, the telescopic ring 12 is connected to the outer wall of the main body 1 in a sliding manner. The top of the telescopic ring 12 is connected to the bottom end of the elastic member 11 through a fastener, and the top end of the elastic member 11 is connected to the main body 1 through a fastener.

[0040] Through the above technical solution, when the telescopic ring 12 is not impacted by the splashing water, the telescopic ring 12 can always be located at the top of the main body 1 by the pulling of the elastic member 11, preventing the telescopic ring 12 from blocking the glass column 3 and causing the glass column 3 to be unable to effectively sense the temperature.

[0041] Specifically, the inner wall of the telescopic ring 12 is connected to the bevel plate 13 through a fastener, and the diffusion blocks 7 are evenly distributed on the diversion disc 4.

[0042] Through the above technical solution, when the water splashes to the side through the plug 15, the splashing water will impact on the bevel plate 13, and then drive the telescopic ring 12 to move downward through the bevel plate 13 to limit the splashing water.

[0043] During use, first, when a fire breaks out inside the building, due to the excessive temperature, the glass column 3 breaks, and the water inside the pipeline is sprayed to the outside through the plug 15. The water enters the inside of the column 5 through the flared block 14. The water entering the inside of the column 5 impacts the spiral blade 9, and the spiral blade 9 is impacted by the water and rotates through the rotating column 10. The rotating column 10 drives the diversion disc 4 to rotate. After the water falls on the diversion disc 4, it is diverted to the inside of the diffusion block 7 through the baffle 6 on the diversion disc 4. The diversion disc drives the diffusion block 7 to rotate, and the diffusion block 7 swings the water inside it to a farther position. When the water sprayed from the main body 1 is relatively large, part of the water splashes to one side through the nozzle. The water impacts on the bevel plate 13, and through the impact force of the water, the bevel plate 13 drives the telescopic ring 12 to move downward to limit the splashing water and prevent the water from dripping vertically onto the ground. When not in use, the telescopic ring 12 is always located outside the main body 1 by the pulling of the elastic member 11, preventing the telescopic ring 12 from covering the glass column 3 and causing the glass column 3 to be unable to effectively sense the external temperature, and then the work can be completed.
