Description

Technical Field

[0001] This utility model belongs to the field of fire protection equipment technology, specifically relating to an automated sprinkler fire extinguishing device for building fire protection. Background Technology

[0002] In the field of building fire safety, automatic sprinkler systems are key equipment for the initial prevention and control of fires. Their reliability and adaptability are directly related to the life safety and property safety of people in the building. At present, most of the mainstream building fire sprinkler systems on the market adopt traditional nozzle structures, which can spray water through small water outlets on the nozzle body during use.

[0003] However, traditional sprinkler-type fire extinguishing devices are prone to clogging during long-term use. The water outlet diameter of traditional sprinklers is generally 1-5 mm. During long-term use, scale, rust, dust, fibers and other impurities in the air can easily adhere to the inner wall of the orifice or block the outlet. Once a fire occurs, the clogged sprinkler cannot deliver water in time or the water volume is insufficient, which will lead to fire extinguishing failure, miss the best time to control the fire, and expand the fire loss.

[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide an automated sprinkler system for building fire protection.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this utility model is to provide an automated sprinkler fire extinguishing device for building fire protection, which can solve the problem of clogging that easily occurs in traditional sprinkler-type fire extinguishing devices during long-term use.

[0007] To achieve the above objectives, a specific embodiment of this utility model provides the following technical solution: an automated sprinkler fire extinguishing device for building fire protection, comprising a base plate, on which a spray pipe and a smoke sensor are fixedly mounted respectively. A closed water guiding mechanism is provided on the spray pipe. The closed water guiding mechanism includes a fixing frame, on which multiple guide rods are fixedly connected. The bottom ends of the multiple guide rods are jointly fixedly connected to a support plate. An electric telescopic rod is fixedly connected to the support plate. A water guiding plate is fixedly connected to the top end of the electric telescopic rod. The water guiding plate is disposed below the spray pipe for sealing the spray pipe.

[0008] In one or more embodiments of this utility model, the water guide plate is provided with a plurality of sliding holes that match the guide rods, and each guide rod is slidably connected inside the sliding hole.

[0009] In one or more embodiments of this utility model, a support spring is fixedly connected to the support plate, the top end of the support spring is fixedly connected to the water guide plate, and the support spring is sleeved on the outside of the electric telescopic rod.

[0010] In one or more embodiments of this utility model, a cylinder is fixedly connected to the water guide plate, the cylinder is sleeved on the support plate and extends to the bottom of the support plate.

[0011] In one or more embodiments of this utility model, a sealing ring is fixedly connected to the bottom end of the nozzle, and the bottom end of the sealing ring is in contact with the upper end face of the water guide plate.

[0012] In one or more embodiments of this utility model, the fixing frame includes two arc-shaped clamps, each of which is fixedly connected with two ear plates, and both sets of ear plates are fixed by bolts.

[0013] In one or more embodiments of this utility model, each of the two arc-shaped clamps is fixedly connected to a connecting seat, and the top end of each guide rod is fixedly connected to the connecting seat.

[0014] Compared with existing technologies, this utility model provides an automated sprinkler system for building fire protection. By using a direct water discharge method from the nozzle, it effectively avoids the problem of traditional nozzles having small orifices that are easily clogged by scale and impurities, ensuring the reliability of the water flow channel during long-term use. In the event of a fire, it can respond quickly and discharge water, thereby improving the stability of fire protection equipment. The water guide plate can normally seal and protect the nozzle, effectively preventing dust, moisture, and other impurities in the air from entering the nozzle, preventing corrosion and scale buildup on the inner wall of the pipe, and ensuring that the device is always in good standby condition. The electric telescopic rod can move the water guide plate, flexibly adjusting its distance from the nozzle. When the distance between the water guide plate and the nozzle is large, the water flows downward; when the distance is small, the water flows outward with greater force under the pressure of the water guide plate, resulting in a stronger impact and improving fire extinguishing efficiency, thus meeting diverse usage needs.

[0023] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0024] like Figures 1 to 5 As shown in the figure, an automated sprinkler system for building fire protection in one embodiment of this utility model includes a base plate 1. A nozzle 2 and a smoke sensor 3 are fixedly installed on the base plate 1. The base plate 1 is a ceiling or wall. The nozzle 2 is installed on it and directly connected to the building's fire water supply network, serving as the outlet for the fire extinguishing water source. Its large-diameter design avoids the problem of easy clogging of traditional small nozzles. The smoke sensor 3 continuously monitors the smoke concentration in the environment. Once a fire hazard is detected, it will send an electrical signal to the external control equipment to initiate fire extinguishing operations.

[0025] The nozzle 2 is equipped with a closed water guiding mechanism, which includes a fixed frame. Multiple guide rods 6 are fixedly connected to the fixed frame, and a support plate 7 is fixedly connected to the bottom ends of the guide rods 6. An electric telescopic rod 8 is fixedly connected to the support plate 7, and a water guiding plate 9 is fixedly connected to the top end of the electric telescopic rod 8. The water guiding plate 9 is positioned below the nozzle 2 and is used to close the nozzle 2. The electric telescopic rod 8 can be extended or retracted to drive the water guiding plate 9 to move up and down. In non-fire conditions, the water guiding plate 9 fits tightly against the bottom of the nozzle 2, providing a sealing and protective function. During firefighting, the distance between the water guiding plate 9 and the nozzle 2 can be adjusted to control the water flow.

[0026] The water guide plate 9 has multiple sliding holes 10 that match the guide rods 6, and each guide rod 6 is slidably connected inside the sliding hole 10. By using the sliding holes 10 in conjunction with the guide rods 6, the water guide plate 9 can be prevented from shifting during the lifting and lowering process, ensuring that it can always remain aligned with the upper spray pipe 2 and the sealing ring 15.

[0027] A support spring 11 is fixedly connected to the support plate 7. The top end of the support spring 11 is fixedly connected to the water guide plate 9, and the support spring 11 is sleeved on the outside of the electric telescopic rod 8. The support spring 11 can provide a continuous upward elastic preload force, which acts on the water guide plate 9, enabling the water guide plate 9 to be tightly pressed against the upper nozzle 2 outlet when not in operation, improving the reliability of static sealing and preventing dust and moisture intrusion.

[0028] A cylinder 14 is fixedly connected to the water guide plate 9. The cylinder 14 is sleeved on the support plate 7 and extends to the bottom of the support plate 7. The cylinder 14 extends downward from the water guide plate 9 to form a sleeve structure, which encloses the internal support plate 7, support spring 11 and the working part of the electric telescopic rod 8. This can effectively prevent water sprayed during fire extinguishing as well as dust and debris in the environment from entering its interior, and avoid corrosion of moving parts and electric telescopic rod 8.

[0029] A sealing ring 15 is fixedly connected to the bottom end of the nozzle 2, and the bottom end of the sealing ring 15 contacts the upper end face of the water guide plate 9. The sealing ring 15 can improve the reliability of the seal, prevent gaps, and ensure that moisture, dust and chemicals that may corrode the pipe in the air cannot enter the interior of the nozzle 2 during long-term standby.

[0030] The mounting bracket includes two arc-shaped clamps 4, each with two ear plates 12 fixedly connected to it. Both sets of ear plates 12 are secured with bolts 13. A connecting seat 5 is fixedly connected to each of the two arc-shaped clamps 4, and the top of each guide rod 6 is fixedly connected to the connecting seat 5. Its overall structure is simple, and during installation and subsequent maintenance, there is no need to disassemble or disturb the main fire protection pipeline, facilitating construction and maintenance.

[0031] Working principle: During use, the electric telescopic rod 8 remains extended under normal conditions, pushing the water guide plate 9 upward so that its upper end face fits tightly against the sealing ring 15 at the bottom of the nozzle 2, completely sealing the outlet of the nozzle 2. At this time, the support spring 11 is in a slightly compressed state, and its elastic force can assist the water guide plate 9 in pressing the sealing ring 15, enhancing the sealing reliability, preventing dust, moisture and other impurities in the air from entering the interior of the nozzle 2, and avoiding corrosion and scaling on the inner wall of the pipe.

[0032] When a fire occurs inside the building and the smoke concentration reaches the detection threshold of the smoke sensor 3, the smoke sensor 3 can capture the fire signal and transmit the electrical signal to the external control equipment. Subsequently, the control equipment activates the electric telescopic rod 8 to retract and drive the water guide plate 9 to slide down along the guide rod 6 to release the closed state of the nozzle 2. At this time, the water in the fire water pipe can flow continuously from the outlet of the nozzle 2 under pressure to carry out fire extinguishing operations.

[0033] During this process, depending on the fire scenario, the distance between the water guide plate 9 and the nozzle 2 can be controlled by adjusting the retraction range of the electric telescopic rod 8, thus achieving two fire extinguishing modes. When the electric telescopic rod 8 retracts significantly, keeping the water guide plate 9 and the nozzle 2 at a large distance, the water flow from the nozzle 2 is unobstructed and can spray downwards naturally. When the electric telescopic rod 8 retracts slightly, keeping the distance between the water guide plate 9 and the nozzle 2 smaller, the water flow hits the water guide plate 9 after flowing out at high speed. Due to its obstruction and pressurization, it can form a powerful jet of water outwards with a stronger impact force.

[0034] After the fire is extinguished, the smoke sensor 3 can no longer detect smoke signals, and can control the electric telescopic rod 8 to extend again, pushing the water guide plate 9 to reset upward along the guide rod 6, restoring the nozzle 2 to its closed state.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
