Description

Technical Field

[0001] This utility model relates to the field of sprinkler head technology, specifically a fire extinguishing sprinkler head. Background Technology

[0002] Fire sprinkler heads (also known as fire extinguishing sprinklers) are key components of automatic sprinkler systems. They automatically spray water to extinguish fires by sensing fires (such as high temperatures or flames) and are widely used in buildings, industries, warehouses, and other locations. Classified by triggering principle, there are thermal sprinkler heads: triggered by the expansion and rupture of a thermal element (such as a liquid-filled glass bulb) when heated; mechanical sprinkler heads: triggered by the deformation or melting of a mechanical structure (such as a fusible alloy or spring) when heated; and electronic sprinkler heads: activated by a solenoid valve linked to smoke or temperature sensors (requires power or signal lines).

[0003] Existing heat-sensitive fire sprinkler heads spray water onto a sprinkler head, causing the water to be sprayed outwards. However, this spraying method results in an overly dispersed water flow with weak impact force, leading to water waste and making it unsuitable for targeted fire suppression. Therefore, a new type of fire sprinkler head is needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a fire extinguishing sprinkler head to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is a fire extinguishing sprinkler head, comprising:

[0006] A spray head, comprising a base, a bracket, and a water outlet pipe, wherein one end of the bracket is fixed to the side of the base and the other end is fixed to the side of the water outlet pipe;

[0007] A flow-gathering component includes a through hole, a steel wire, and a water-gathering tank. The through hole is located at the upper end of the outlet pipe, and the steel wire is inserted into the through hole with both ends bent. There are four water-gathering tanks located at the lower end of the outlet pipe, and they are arranged in a ring-shaped symmetrical distribution.

[0008] Furthermore, the current-gathering assembly also includes a through hole, a drainage pipe, and a locking block. The through hole is located at the lower end of the support, and one end of the locking block is fixed to the lower end of the drainage pipe, while the other end is inserted into the through hole.

[0009] Furthermore, the diameter of the upper port of the drainage pipe is larger than the diameter of the lower port, and the diameter of the lower port of the drainage pipe is the same as the diameter of the upper port of the outlet pipe.

[0010] Furthermore, the upper end diameter of the water outlet pipe is smaller than the lower end diameter, and the steel wire is located in the middle of the water outlet pipe.

[0011] Furthermore, the spray head also includes a screw connector and a glass tube. The screw connector is fixed to the upper end of the base and connected to an external water supply pipe, while the glass tube is fixed to the middle of the lower end of the base by a plunger.

[0012] Furthermore, it also includes a damage prevention component, which includes a first clamping plate, an opening, a second clamping plate, and a connecting post. The first clamping plate and the second clamping plate are clamped on both sides of the bracket. The opening is opened at both ends of the first clamping plate. The connecting post is fixed at both ends of the side of the second clamping plate and is inserted into the opening.

[0013] Furthermore, the first and second clamps are placed on the upper end of the drainage tube, and the connecting post is located between the two supports.

[0014] This utility model has the following beneficial effects:

[0015] This invention, through its flow-concentrating component, allows water to flow out through the holes in the screw joint, base, and plunger after the glass tube breaks, falling into the drainage pipe and then converging through the steel wire in the outlet pipe. Subsequently, most of the water is sprayed out from the four water-concentrating tanks. This design enables the fire sprinkler head to form a focused water flow, increasing the water flow impact force, reducing water waste, and improving fire extinguishing efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-3 As shown, this utility model is a fire extinguishing sprinkler head, comprising:

[0026] The spray head includes a base 11, a bracket 12 and a water outlet pipe 13. One end of the bracket 12 is fixed to the side of the base 11 and the other end is fixed to the side of the water outlet pipe 13.

[0027] The diameter of the upper end of the water outlet pipe 13 is smaller than the diameter of the lower end;

[0028] The spray head also includes a screw connector 10 and a glass tube 14. The screw connector 10 is fixed to the upper end of the base 11 and connected to the external water supply pipe. The glass tube 14 is fixed to the middle of the lower end of the base 11 by a plunger.

[0029] The screw connector 10 is used to connect the spray head to the external water pipe. The base 11 serves as a support and connection. The bracket 12 serves as a connection and is used to connect the water outlet pipe 13. The water outlet pipe 13 is used to spray water. The glass tube 14 is a heat-sensitive element, filled with liquid. When heated, it expands and bursts, triggering the water spray.

[0030] The current-gathering component includes a through hole 20, a steel wire 21, and a water-gathering tank 22. The through hole 20 is opened at the upper end of the water outlet pipe 13. The steel wire 21 is inserted into the through hole 20 and bent at both ends. There are four water-gathering tanks 22, which are opened at the lower end of the water outlet pipe 13 and are distributed in a ring symmetrical manner.

[0031] The current-gathering assembly also includes a through hole 23, a drain pipe 24, and a locking block 25. The through hole 23 is opened at the lower end of the bracket 12, and one end of the locking block 25 is fixed to the lower end of the drain pipe 24, while the other end is inserted into the through hole 23.

[0032] The diameter of the upper port of the drainage pipe 24 is larger than the diameter of the lower port, and the diameter of the lower port of the drainage pipe 24 is the same as the diameter of the upper port of the outlet pipe 13.

[0033] Steel wire 21 is located in the middle of the outlet pipe 13;

[0034] The through hole 20 is used to connect the steel wire 21, which can reduce the divergence of water flow due to inertia or turbulence, making the water column more focused. The water collection tank 22 can guide the water flow. The through hole 23 and the clamp 25 are used to connect the drain pipe 24, which is used to receive the falling water flow.

[0035] Working principle:

[0036] The lower end of the drain pipe 24 is inserted into the through hole 23 using the locking block 25. The screw connector 10 is screwed onto the water outlet of the water supply pipe reserved above where a fire is likely to occur. When a fire occurs, the glass tube 14 is ruptured by heat, and the water flows out through the hole between the screw connector 10, the base 11 and the plunger, falling into the drain pipe 24. It then converges through the steel wire 21 in the outlet pipe 13, and then most of the water flows out from the four water collection tanks 22 and falls to the fire source below.

[0037] This step allows the fire sprinkler head to create a focused water flow, increasing the water flow impact force, reducing water waste, and improving fire extinguishing efficiency.

[0038] Please see Figure 4 As shown, this embodiment, based on the above embodiment, further includes:

[0039] The damage prevention component includes a first clamping plate 30, an opening 31, a second clamping plate 32, and a connecting post 33. The first clamping plate 30 and the second clamping plate 32 are clamped on both sides of the bracket 12. The opening 31 is opened at both ends of the first clamping plate 30. The connecting post 33 is fixed at both ends of the side of the second clamping plate 32 and is inserted into the opening 31.

[0040] The first clamping plate 30 and the second clamping plate 32 are placed on the upper end of the drainage tube 24, and the connecting column 33 is located between the two supports 12;

[0041] The first clamping plate 30 and the second clamping plate 32 serve a protective function, clamping the glass tube 14 in the middle. The connecting post 33 and the opening 31 serve a connecting function, which can connect the first clamping plate 30 and the second clamping plate 32.

[0042] Working principle:

[0043] The first clamp 30 is attached to one side of the bracket 12. Holding the second clamp 32, the connecting post 33 is aligned with the opening 31 and pressed down. The first clamp 30 and the second clamp 32 are then released. At this time, the first clamp 30 and the second clamp 32 fall onto the drainage tube 24 and wrap the glass tube 14 inside. Holding the base 11, the screw connector 10 is aligned with the outlet of the external water supply pipe. The screw connector 10 is tightened with a wrench. Then, holding the first clamp 30 with one hand, the second clamp 32 is pulled forcefully with the other hand to remove the first clamp 30 and the second clamp 32, exposing the glass tube 14.

[0044] This step is to prevent the glass tube 14 from being damaged by the installation tool when installing the sprinkler head.

[0045] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
