Description

Technical Field

[0001] This invention relates to the field of fire protection equipment technology, and in particular discloses a fire sprinkler system. Background Technology

[0002] In typical residential and public buildings, common fire-fighting equipment includes fire extinguishers and fire hose boxes. Fire extinguishers have an expiration date and become useless without regular maintenance and replacement. Fire hose boxes generally contain fire hydrants and fire hoses connected to the building's fire water supply lines. One end of the fire hose is connected to the fire hydrant, and the other end is equipped with a water nozzle. Fire hose boxes are usually located in public areas such as building corridors or stairwells. Moreover, the fire hydrants in most building fire hose boxes require the activation of a fire pump to supply water, making the operation process complicated. In the event of a fire in a residential building, the initial fire is usually small. If it can be extinguished in time, it can prevent harm to people's lives and property and avoid public disasters. When faced with a fire, people are prone to panic and frantically search for fire extinguishers or water hoses to spray water to extinguish the fire, thus failing to minimize the damage in time.

[0003] When faced with sudden disasters, especially fires, people are prone to panic and fail to take effective and correct measures. The situation at a fire scene can change rapidly and the fire can continue to spread. Panic and incorrect actions may cause them to miss the opportunity to extinguish the fire. If the spread and ravages of the fire can be contained in time, fire casualties and fire losses can be avoided. Summary of the Invention

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this invention is to provide a spraying device that can be used immediately in a residence, and which can extinguish fires before they spread without requiring the user to worry about how to use the fire extinguishing spraying device.

[0005] To achieve the above objectives, the present invention provides a fire sprinkler system, comprising a reel, a fire hose, and a cover; the reel is fixed to an external support, the fire hose is wound onto the reel, and a quick-release structure is provided between the cover and the reel, with the cover covering the reel via the quick-release structure; the reel includes a base, an inner spacer ring disposed on the base, and a middle spacer ring disposed outside the inner spacer ring; the inner spacer ring has a first slit, and a first limiting rod is provided on the upper edge of one side of the inner spacer ring; the fire hose... The head end of the hose is wound inside the inner diaphragm ring. The free end of the fire hose passes through the cut in the inner diaphragm ring and is wound around the outside of the inner diaphragm ring in the opposite direction to the winding direction inside the inner diaphragm ring. The middle diaphragm ring is sleeved on the outside of the fire hose wound around the inner diaphragm ring. The chassis is provided with a through hole. The head end of the fire hose passes through the through hole and is connected to the water supply pipe pre-installed in the external support. The tail end of the fire hose is provided with a fire nozzle. The fire nozzle is limited on the winding reel by the first limiting rod.

[0006] Furthermore, it also includes an outer ring located on the chassis outside the central partition ring, with the outer ring surrounding the central partition ring; the central partition ring has a second cut, through which the free end of the fire hose wound around the outside of the inner partition ring passes and is wound around the outside of the central partition ring in a direction opposite to the outer winding direction of the inner partition ring; the outer ring is used to fit around the outside of the fire hose wound around the outside of the central partition ring.

[0007] Furthermore, the chassis is also provided with multiple central ring holes, which are spaced apart around the central axis of the chassis. The central ring holes are located between the outer ring and the inner partition ring. The partition ring is provided with multiple first fitting rods, which are used to engage with the central ring holes to fix the partition ring to the chassis.

[0008] Furthermore, the chassis is provided with multiple outer ring holes; the multiple outer ring holes are spaced apart along the edge of the chassis, and the outer ring is provided with multiple second fitting rods, which are used to engage with the outer ring holes so that the outer ring is fixed to the chassis.

[0009] Furthermore, the outer ring is also provided with a clamping rod, and a receiving gap is formed between the clamping rod and the side wall of the outer ring. The free end of the fire hose wound around the outside of the middle partition ring passes through the receiving gap and is clamped and positioned on the winding reel.

[0010] Furthermore, the chassis has multiple fixing plates around its outer periphery, and the fixing plates protrude outward along the radial direction of the chassis. The cover is disc-shaped, and the periphery of the cover extends downward and radially inward to form a conical claw portion. The conical claw portion is used to clamp the edge of the fixing plate so that the cover can be detachably placed on the winding reel.

[0011] Furthermore, the mounting plate or chassis has mounting holes on its edge; the fire sprinkler system also includes fasteners for securing the mounting plate and chassis together to an external support through the mounting holes. Preferably, each fixing plate is provided with fixing holes.

[0012] Preferably, the fastener is a bolt.

[0013] Furthermore, it also includes a base located below the chassis, on which a connecting pipe for connecting to the tap water system is provided. The outlet end of the connecting pipe passes through a through hole on the chassis and connects to the head end of the fire hose, so that the connecting pipe is connected to the fire hose.

[0014] Furthermore, at least two second limiting rods are provided at the top of the central partition ring. The first limiting rod and the two second limiting rods together clamp the fire spray gun to limit the fire spray gun on the winding reel.

[0015] Furthermore, the fire hose is provided with a pipe connector at its head end, which passes through the through hole of the chassis and is detachably connected to the pipe connector of the water supply pipe pre-installed inside the external support component.

[0016] The principle of this invention is as follows: The fire sprinkler system mainly includes a reel, a fire hose, and a cover. The reel connects directly to the pre-installed water supply pipe inside the residential wall through through holes and pipe joints on the base, eliminating the need for a fire pump and complicated valve operation. To ensure smooth hose dragging, the reel employs a multi-layer concentric ring structure—an inner diaphragm ring and a middle diaphragm ring. The head end of the fire hose is first wound inside the inner diaphragm ring, passes through the first cut, and then wound in the opposite direction around the outer side of the inner diaphragm ring, where it is then stopped by the middle diaphragm ring. This reverse winding structure ensures that the hose will not become tangled due to internal twisting during emergency dragging.

[0017] In addition, a quick-release mechanism (such as the engagement of the tapered claw portion around the cover with the fixing plate on the edge of the chassis) is provided between the cover and the reel, allowing for quick and easy opening by hand without tools. The fire nozzle connected to the end of the fire hose is limited by the first limiting rod on the inner diaphragm ring, ensuring that it is securely placed on the reel when not in use, thus enabling emergency operation of opening the cover, pulling out the nozzle, and spraying water immediately. The beneficial effects of this invention are: First, by directly connecting to the tap water supply pipe, it avoids the complicated steps of starting the fire pump required by traditional devices, achieving true "ready to use" and is especially suitable for family homes without professional fire protection facilities. Secondly, the quick-release design of the cover allows users to open it quickly by hand in an emergency, allowing them to access the fire hose immediately. Third, the reverse layered winding design of the fire hose in the reel fundamentally solves the hidden danger of the hose easily getting tangled and knotted during emergency dragging, ensuring smooth water spraying. Fourth, the device can operate using daily tap water pressure and does not require regular replacement or disposal like fire extinguishers. It is long-lasting and maintenance-free, effectively containing fires in their initial stages and significantly reducing the harm to life and property caused by fires. Attached Figure Description

[0020] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0021] Please see Figures 1 to 13 As shown, the present invention provides a fire sprinkler device that can be connected to a water supply pipe of a pre-installed tap water system inside the wall of a residential house, and the sprinkler device can be fixed to the wall so that it can be used directly to spray sand and water to extinguish fires in the event of a fire.

[0022] Please combine Figures 1-3As shown, the fire sprinkler device of the present invention includes a take-up reel 10, a fire hose 20, and a cover 30. The fire hose 20 is wound around the take-up reel 10, and the cover 30 is detachably installed on the fire hose 20 and the take-up reel 10. The take-up reel 10 includes a base 11, a middle partition ring 12 and an outer ring 13 disposed on the base 11. An inner partition ring 111 is provided in the middle of the base 11. A first cut 112 is provided on the inner partition ring 111. A first limiting rod 113 is also provided at the top of the inner partition ring 111. A plurality of middle ring holes 114 and a plurality of outer ring holes 115 are provided on the base 11. The plurality of middle ring holes 114 are arranged around the inner partition ring 111, and the plurality of outer ring holes 115 are arranged around the inner partition ring 111. The outer ring holes 115 are located at the edge of the base 11, and the middle ring holes 114 are located in the middle of the base 11 and outside the inner partition ring 111.

[0023] Specifically, the outer edge of the chassis 11 is provided with a plurality of fixing plates 116 protruding radially, and fixing holes 117 are provided on the fixing plates 116.

[0024] The middle partition ring 12 has a cut 121, and two second limiting rods 122 are provided on the top of the middle partition ring 12. The lower end of the middle partition ring 12 has a plurality of first fitting rods 123 that are inserted into the middle ring hole 114 on the chassis 11. The inner side of the outer ring 13 has a clamping rod 131, and the lower end of the outer ring 13 has a plurality of second fitting rods 132 that are inserted into the outer ring hole 115 on the chassis 11.

[0025] When not in use, the fire hose 20 is wound inside the winding reel 10, and the head end of the fire hose 20 is provided with a pipe joint 21, and the tail end of the fire hose 20 is provided with a fire spray gun 22.

[0026] Preferably, the fire nozzle 22 is equipped with an elastic hanging plate and a grip ring. When using the fire hose 20 and the fire nozzle 22, one hand can hold the elastic hanging plate and the other hand can hold the grip ring, which facilitates water spraying for fire extinguishing. The elastic hanging plate can also be temporarily hung on a suitable external object after the fire is extinguished.

[0027] The cover 30 is arranged in the shape of a disc. The periphery of the cover 30 extends downward and radially inward to form a conical claw portion 31. The circumferential diameter of the lower edge of the conical claw portion 31 is slightly smaller than the outer diameter of the fixed plates 116 provided on the base plate 11 of the winding reel 10, so that the conical claw portion 31 and the edge of the fixed plate 116 form a hook engagement.

[0028] Please combine Figures 4-7 As shown, the fire hose 20 is wound and rolled up onto the winding reel 10 in the following manner: First, curl the head end of the fire hose 20 and insert it into the inner diaphragm ring 111 of the chassis 11 (leaving a portion for installing the pipe connector 21 at the head end); then, pass the fire hose 20 outward from the first cut 112 of the inner diaphragm ring 111, and curl the portion of the fire hose 20 that has passed through the first cut 112 in the opposite direction (opposite to the curling direction of the head end) onto the outer ring of the inner diaphragm ring 111; when the number of curls of the fire hose 20 is close to the inner diameter of the middle diaphragm ring 12, insert the first fitting rod 123 at the lower end of the middle diaphragm ring 12 into the middle ring hole 114 of the chassis 11, so that the middle diaphragm ring 12 is fixedly installed on the chassis 11. Next, the fire hose 20 is passed through the second cut 121 of the central partition ring 12 and then wound around the outer perimeter of the central partition ring 12 in a reverse curling manner. When the number of turns of the fire hose 20 is close to the inner diameter of the outer ring 13, the second fitting rod 132 at the lower end of the outer ring 13 is inserted into the outer ring hole 115 of the chassis 11, so that the outer ring 13 is fixedly installed on the chassis 11. Then, the fire hose 20 is passed through the clamping rod 131 on the inner side of the ring wall of the outer ring 13, so that the fire hose 20 is clamped by the clamping rod 131, and then the tail end of the fire hose 20 is pulled above the coiled fire hose 20 and the winding reel 10.

[0029] After the fire hose 20 is wound into the take-up reel 10, the head end of the fire hose 20, which is wound in the inner spacer ring 111 on the chassis 11, is pulled out and a pipe connector 21 is installed at this end. Then, a fire nozzle 22 is installed at the tail end of the fire hose 20. After the fire nozzle 22 is connected to the fire hose 20, it can be placed above the take-up reel 10. The fire nozzle 22 is held in place by the first limiting rod 113 on the inner spacer ring 111 and the two second limiting rods 122 on the middle spacer ring 12, so that it is securely placed on the take-up reel 10.

[0030] Please see Figures 8-12 As shown, the base 11 of the reel 10 has a through hole 118 in the center. The through hole 118 is used for the adapter 41 of the water supply pipe 40 of the pre-installed water supply system in the wall of a residential house (hereinafter referred to as the wall). When the fire sprinkler device of the present invention is installed at home, the adapter 41 is first installed on the water supply pipe 40 of the pre-installed water supply system in the wall. Then, the fire hose 20 that has been wound and wound is connected to the reel 10 and placed at the pipe opening of the water supply pipe 40, so that the adapter 41 passes through the through hole 118 in the center of the base 11. Then, the reel 10 is fastened to the wall by bolts 42 passing through the fixing holes 117 on the outer edge of the base 11 (pre-drilling holes in the wall is optional, and expansion bolts are selected as the fasteners). After that, the pipe connector 21 at the head end of the fire hose 20 is connected to the adapter 41.

[0031] After installation, cover the take-up reel 10 with the cover 30, and use the tapered claws 31 on the outer periphery of the cover 30 to elastically clamp the edges of the fixing plates 116 on the outer edge of the chassis 11 of the take-up reel 10, so that the cover 30 is securely installed on the take-up reel 10.

[0032] Because the fire sprinkler device of the present invention connects the pipe connector 21 at the end of the fire hose 20 directly to the pipe connector 41 of the pre-installed water supply pipe 40 in the wall during installation, without connecting a switch valve or water supply pump, in the event of a fire, the cover 30 can be quickly lifted (the cone claw part 31 is more convenient and faster to disassemble than the traditional buckle), and the fire nozzle 22 at the end of the fire hose 20 can be picked up directly, and the fire hose 20 can be pulled out together. The fire nozzle 22 can then be operated to spray water directly to extinguish the fire.

[0033] Specifically, the cover 30 has a hollow shell structure and covers the take-up reel 10. The cover 30 only uses the conical claw part 31 around its periphery to hook and grasp the edges of the fixing plates 116 on the outer periphery of the base 11 of the take-up reel 10. There are no other bolts, switches, locks, or buckles. The cover 30 is disc-shaped, and the conical claw part 31 and the upper end of the cover 30 form a gripping protrusion that is easy to grasp (in actual use, silicone anti-slip stickers can be pasted on this part, or an anti-slip texture structure can be added here during manufacturing). In case of an emergency such as a fire, the cover 30 can be easily and quickly opened by hand.

[0034] Specifically, the fire hose 20 wound in the reel 10 has the opposite winding direction of the portion of the inner partition ring 111 wound around it to the portion of the middle partition ring 12 wound around it. Therefore, when the fire hose 20 is pulled out of the reel 10, it does not produce messy curling compared to the same-direction winding method, making it easier to use.

[0035] Please see Figure 13 As shown, when the fire sprinkler system of the present invention is installed in a home, if there is no water supply pipe 40 for the tap water system, a base 50 can be added below the chassis of the reel 10, and a connecting pipe 51 for connecting to the tap water system can be installed on the base 50. The outlet end of the connecting pipe 51 passes through the through hole 118 in the center of the chassis 11 and is placed inside the reel 10 so that the pipe connector 21 at the head end of the fire hose 20 can be connected; that is, adding the base 50 can improve the versatility of the installation site of the fire sprinkler system of the present invention.

[0036] In the event of a fire, panic and confusion can easily lead to disorganization. However, the fire sprinkler system of this invention offers ease of use, speed, and practicality. In the event of a fire, simply lift the cover 30 by hand, pick up the fire nozzle 221, and drag out the fire hose 20 to operate the fire nozzle 22 and spray water directly to extinguish the fire. This user-friendly sprinkler system avoids incorrect operation in emergency fire situations, enabling timely water spraying to extinguish flames and minimizing damage.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
