Description

Technical Field

[0001] This utility model relates to the field of fire sprinkler technology, and more specifically, to a fire sprinkler for fire fighting. Background Technology

[0002] Fire sprinklers are a key component of automatic sprinkler systems, used to automatically spray water to extinguish fires when they occur. They are typically installed on the ceiling or walls of a building and can be activated quickly upon detecting a fire, spraying water to cover the fire area, thereby controlling and extinguishing the fire.

[0003] Most existing fire sprinklers only have one nozzle and a splash plate below it, causing water to spray outward through the splash plate. In this case, a blank area in the middle of the spray can easily appear, affecting the fire extinguishing effect.

[0004] Meanwhile, in existing technologies, fire sprinklers mainly spray droplets of water for fire extinguishing. However, when a fire occurs, a lot of dust is generated and dispersed in the air, which can cause people at the fire scene to suffocate due to inhaling large amounts of dust. Existing technologies use atomizing sprinklers to atomize the sprayed water to reduce dust, but the atomized water flow is less effective at extinguishing fires, affecting the fire extinguishing effect. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the problems existing in the prior art, this utility model provides a fire sprinkler head for fire fighting, so as to solve the technical problems mentioned in the background art that the fire sprinkler head for fire fighting has blank areas when spraying fire extinguishing and has poor fire extinguishing and dust suppression effects.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A fire sprinkler head for fire fighting includes a connecting pipe. Multiple water outlet pipes are evenly arranged on the bottom sidewall of the connecting pipe. A two-way pipe is provided at the tail end of each water outlet pipe. One end of the two-way pipe has a spray pipe pointing upwards, and the other end has a spray pipe pointing downwards. An atomizing nozzle is provided on the spray pipe. A spray head is provided at the bottom end of the spray pipe, and a splash plate is provided below the spray head. A sealing plug is provided at the bottom of the connecting pipe. A connecting section is provided at the bottom end of the sealing plug. A pressure member is provided on the connecting section slidingly to the outside of the connecting pipe. A support section is threaded at the bottom outer end of the connecting pipe. An adjusting member is threaded on the support section. A heat-sensitive glass ball is placed between the adjusting member and the pressure member.

[0010] The present invention is further configured such that a protective cover is foldably fitted on the outer side of the thermosensitive glass ball, and the top end of the protective cover is detachably connected to the pressing member and the bottom end is detachably connected to the supporting section. The protective cover can intercept the flying debris when the thermosensitive glass ball breaks, preventing damage caused by the flying glass debris.

[0011] The present invention is further configured such that a first magnetic absorbing piece is provided at the top and bottom of the protective cover, and a second magnetic absorbing piece is provided at the bottom of the pressing member and the top of the supporting section. The first magnetic absorbing piece and the second magnetic absorbing piece are magnetically attracted to each other. The protective cover can be conveniently installed and disassembled between the supporting section and the pressing member through the cooperation of the first magnetic absorbing piece and the second magnetic absorbing piece.

[0012] The present invention is further provided with an internal hexagonal adjustment groove at the bottom end of the adjustment component, which facilitates the adjustment component to be rotated and adjusted by means of a tool, thereby achieving the pressing of the thermosensitive glass ball.

[0013] The present invention is further configured such that a first connecting frame is provided on the support section, a first connecting ring is provided at the top of the first connecting frame, and the first connecting ring is threaded onto the bottom end of the connecting pipe. Through the cooperation of the first connecting frame and the first connecting ring, the support section can be stably installed at the bottom end of the connecting pipe, thereby realizing the stable installation of the adjusting component. This facilitates the installation, disassembly and replacement of the thermal glass ball.

[0014] The present invention is further configured such that a second connecting frame is provided on the splash plate, and a second connecting ring is provided at the top of the first connecting frame. The first connecting ring is screwed onto the outside of the spray pipe. The splash plate is stably installed at the bottom of the spray head through the cooperation of the second connecting frame and the second connecting ring.

[0015] The present invention is further configured such that the top end of the adjusting member and the bottom end of the pressing member are provided with limiting grooves to cooperate with the thermal glass ball. The setting of the limiting grooves can improve the stability of the thermal glass ball when it is installed between the adjusting member and the pressing member.

[0016] The present invention is further configured such that a limiting platform is provided inside the connecting pipe, and a limiting edge is provided at the bottom end of the connecting pipe. Both the limiting platform and the limiting edge are used to limit the movement of the sealing plug. When the sealing plug is in a blocking state against the water outlet pipe, the top of the sealing plug abuts against the bottom of the limiting platform, thereby enhancing the sealing performance of the sealing plug. When the sealing plug moves to below the water outlet pipe, the limiting edge limits the sealing plug to prevent the sealing plug from moving out of the bottom of the connecting pipe, thereby sealing the bottom of the connecting pipe and ensuring that the water can flow smoothly through the water outlet pipe.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a fire sprinkler head for fire fighting, which has the following beneficial effects:

[0019] 1. This utility model features a foldable protective cover on the outside of the thermosensitive glass ball, preferably with heat-conducting holes. In the event of a fire, the thermosensitive glass ball will shatter, and the protective cover can intercept the debris generated by the shattering, preventing injury caused by the flying debris from the thermosensitive glass ball.

[0020] 2. This utility model features a sealing plug, a connecting section, and a pressing component inside the connecting pipe. When the thermosensitive glass ball is in its normal state, it presses against the pressing component, thus sealing and fixing the sealing plug inside the connecting pipe and preventing water from entering the outlet pipe. When the thermosensitive glass ball ruptures due to high temperature and the internal temperature-sensitive liquid expands, it loses its pressure on the pressing component. As a result, the sealing plug, under the action of water pressure inside the connecting pipe, pushes the protective cover downward, thereby connecting the connecting pipe and the outlet pipe. This allows the water in the connecting pipe to be discharged outward through the outlet pipe, achieving spray fire extinguishing. In this way, automatic sensing can be achieved when a fire occurs.

[0021] 3. In this utility model, a spray pipe and a mist pipe are connected to the tail end of the water outlet pipe via a two-way splitter pipe. An atomizing nozzle is installed in conjunction with the mist pipe, and a spray head is installed in conjunction with the spray pipe. This allows the water flowing into the water outlet pipe to flow to the mist pipe and the spray pipe respectively through the splitter pipe. The water entering the mist pipe is sprayed out as a water mist under the action of the atomizing nozzle, while the water entering the spray pipe is sprayed out as a spray. This ensures sufficient fire suppression through spraying and reduces airborne dust through atomization, preventing suffocation caused by excessive dust and other harmful factors during fire suppression, thus improving the fire suppression effect. Furthermore, this utility model has a splash plate at the bottom of each spray head, ensuring that the spray from a group of fire sprinklers reaches all areas without dead zones, avoiding the situation where the middle of the area cannot be sprayed, as is common with traditional fire sprinklers.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0030] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0031] Please see Figures 1-5 A fire sprinkler head for fire protection includes a connecting pipe 1. Multiple water outlet pipes 2 are evenly arranged on the bottom side wall of the connecting pipe 1. A two-way pipe 3 is arranged at the tail end of the water outlet pipe 2. A spray pipe 4 is arranged upward at one end of the two-way pipe 3, and a spray pipe 5 is arranged downward at the other end. An atomizing nozzle 6 is arranged on the spray pipe 4, and a spray nozzle 7 is arranged at the bottom end of the spray pipe 5.

[0032] In this way, the water flowing into the outlet pipe 2 can be distributed to the spray pipe 4 and the sprinkler pipe 5 through the diversion pipe. The water flowing into the spray pipe 4 will be sprayed out in the form of water mist under the action of the atomizing nozzle 6, and the water flowing into the sprinkler pipe 5 will be sprayed out in the form of a spray under the action of the sprinkler head 7. In this way, when extinguishing a fire, it can ensure the suffocation caused by the spraying method and reduce the dust in the air by the atomizing method, so as to avoid the suffocation caused by the large amount of dust and other harmful factors in the fire control. This improves the fire extinguishing effect.

[0033] This utility model provides a splash plate 8 below each sprinkler head 7, so that the spray liquid sprayed by a group of fire sprinklers can reach the area without dead corners, avoiding the situation where the middle of the traditional fire sprinkler cannot be sprayed.

[0034] In this invention, a sealing plug 9 is provided at the bottom of the inner part of the connecting pipe 1, a connecting section 10 is provided at the bottom of the sealing plug 9, a pressing member 11 is provided on the outside of the connecting pipe 1 through the sliding extension of the connecting section 10, a support section 12 is threaded at the bottom outer end of the connecting pipe 1, an adjusting member 13 is threaded on the support section 12, and a thermosensitive glass ball 14 is provided between the adjusting member 13 and the pressing member 11.

[0035] Please see Figures 1-5 As one embodiment of the thermal glass ball 14: the outer side of the thermal glass ball 14 is foldably fitted with a protective cover 15. The top end of the protective cover 15 is detachably connected to the pressing member 11 and the bottom end is detachably connected to the support section 12. The protective cover 15 can intercept the flying debris when the thermal glass ball 14 explodes, preventing damage caused by the flying glass debris.

[0036] Please see Figures 1-5 As one embodiment of the protective cover 15: the top and bottom of the protective cover 15 are provided with first magnetic absorbing plates 16, and the bottom of the pressing member 11 and the top of the support section 12 are provided with second magnetic absorbing plates 17. The first magnetic absorbing plates 16 and the second magnetic absorbing plates 17 are magnetically attracted to each other. Through the cooperation of the first magnetic absorbing plates 16 and the second magnetic absorbing plates 17, the protective cover 15 can be conveniently installed and disassembled between the support section 12 and the pressing member 11. During installation, the top of the protective cover 15 is first separated from the pressing member 11, so that the thermal glass ball 14 is placed between the adjusting member 13 and the pressing member 11 and screwed in to fix it. Then the top of the protective cover 15 is connected to the pressing member 11.

[0037] Please see Figures 1-5 As one embodiment of the adjusting member 13: the bottom end of the adjusting member 13 is provided with an internal hexagonal adjustment groove 18, which makes it easy to rotate and adjust the adjusting member 13 with a tool, thereby achieving the pressure of the thermal glass ball 14.

[0038] Please see Figures 1-5 As one embodiment of the support section 12: a first connecting frame 19 is provided on the support section 12, and a first connecting ring 20 is provided at the top of the first connecting frame 19. The first connecting ring 20 is threaded onto the bottom end of the connecting pipe 1. Through the cooperation of the first connecting frame 19 and the first connecting ring 20, the support section 12 can be stably installed at the bottom end of the connecting pipe 1, thereby realizing the stable installation of the adjusting component 13.

[0039] Please see Figures 1-5 As one embodiment of the splash plate 8: a second connecting frame 21 is provided on the splash plate 8, a second connecting ring 22 is provided at the top of the first connecting frame 19, and the first connecting ring 20 is screwed onto the outside of the spray pipe 5. The splash plate 8 is stably installed at the bottom of the spray head 7 through the cooperation of the second connecting frame 21 and the second connecting ring 22.

[0040] Please see Figures 1-5 As one embodiment of the adjusting member 13: the top end of the adjusting member 13 and the bottom end of the pressing member 11 are both provided with limiting grooves 23 to cooperate with the thermal glass ball 14. The setting of the limiting grooves 23 can improve the stability of the thermal glass ball 14 when it is installed between the adjusting member 13 and the pressing member 11.

[0041] Please see Figures 1-5 As one implementation of the connecting pipe 1: a limiting platform 24 is provided inside the connecting pipe 1, and a limiting edge 25 is provided at the bottom end of the connecting pipe 1. Both the limiting platform 24 and the limiting edge 25 are used to limit the movement of the sealing plug 9. When the sealing plug 9 is in the blocking state of the water outlet pipe 2, the top of the sealing plug 9 presses against the bottom of the limiting platform 24, thereby strengthening the sealing performance of the sealing plug 9. When the sealing plug 9 moves to below the water outlet pipe 2, the limiting edge 25 limits the sealing plug 9 to prevent the sealing plug 9 from moving out of the bottom of the connecting pipe 1, thereby sealing the bottom of the connecting pipe 1 and ensuring that the water can flow smoothly through the water outlet pipe 2.

[0042] In summary:

[0043] This utility model provides a foldable protective cover 15 on the outside of the thermal glass ball 14, preferably with heat conduction holes on the protective cover 15. In this way, when a fire occurs, the thermal glass ball 14 will shatter, and the protective cover 15 can intercept the debris generated by the shattering, thus avoiding injury caused by the flying debris of the thermal glass ball 14.

[0044] This invention features a sealing plug 9, a connecting section 10, and a pressing member 11 arranged inside the connecting pipe 1. When the thermosensitive glass ball 14 is in its normal state, it presses against the pressing member 11, thereby sealing and fixing the sealing plug 9 inside the connecting pipe 1 and preventing water from entering the outlet pipe 2. When the thermosensitive glass ball 14 expands and ruptures due to high temperature, it loses the pressure on the pressing member 11, causing the sealing plug 9 to move downward under the water pressure inside the connecting pipe 1. This allows the connecting pipe 1 to connect with the outlet pipe 2, enabling the water in the connecting pipe 1 to be discharged outward through the outlet pipe 2, thus achieving automatic fire suppression. In this way, automatic sensing can be achieved when a fire occurs.

[0045] In this invention, a spray pipe 5 and a mist pipe 4 are connected to the tail end of the water outlet pipe 2 via a two-way pipe 3. An atomizing nozzle 6 is installed in conjunction with the mist pipe 4, and a spray head 7 is installed in conjunction with the spray pipe 5. This allows the water flowing into the water outlet pipe 2 to flow through the two-way pipe to the mist pipe 4 and the spray pipe 5 respectively. The water flowing into the mist pipe 4 is sprayed out in the form of a water mist under the action of the atomizing nozzle 6, while the water flowing into the spray pipe 5 is sprayed out in the form of a spray under the action of the spray head 7. This ensures that during fire extinguishing, the spraying method guarantees sufficient fire suppression, while the atomized spray reduces dust and other pollutants in the air, preventing suffocation caused by excessive dust and other harmful factors during fire control, thus improving the fire extinguishing effect.

[0046] Furthermore, each sprinkler head 7 is equipped with a splash plate 8 at its bottom, which ensures that the spray liquid from a group of fire sprinklers covers the area without dead corners, avoiding the situation where the middle of the traditional fire sprinkler cannot be sprayed.
