Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and in particular to a multi-directional fire sprinkler head based on a reflective heat-concentrating cover. Background Technology

[0002] Fire sprinkler systems are among the most common and effective automatic fire extinguishing facilities in buildings. Their core component is the fire sprinkler head, which is activated by heat-sensitive elements (such as glass bulbs or fusible alloys) when heated, opening the water path to spray water for fire extinguishing. However, existing conventional fire sprinkler heads have several significant technical drawbacks: Low thermal sensitivity: Sprinkler heads typically rely on natural convection of the surrounding air to heat the heat-sensitive element. In the early stages of a fire, heat may accumulate at higher levels of the ceiling, and the heat-sensitive element may take a long time to reach its operating temperature, leading to a delayed response and missed opportunities for optimal fire suppression. Short detection range: The heat-sensitive element can only sense the temperature within its immediate vicinity. For fire sources that are far away or behind obstacles, the sensing capability drops sharply, easily resulting in blind spots. Lack of directionality in spraying: Once activated, traditional sprinkler heads typically spray water downwards or outwards, lacking directionality. This means that the water flow may not accurately reach the base of the fire source, instead being wasted in unburned areas, resulting in low fire suppression efficiency and significant water damage. Summary of the Invention

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a multi-directional fire sprinkler head based on a reflective heat-concentrating cover, which can solve the above-mentioned problems.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a multi-directional fire sprinkler head based on a reflective heat-concentrating cover, including a water supply main pipe 1, a valve control system, multiple sprinkler units and a reflective heat-concentrating cover sprinkler head. The valve control system is set at the front end of the water supply main pipe 1 and the sprinkler unit inlet. The multiple sprinkler units are set on the water supply main pipe 1, and the reflective heat-concentrating cover sprinkler head is set at the output end of the multiple sprinkler units. The valve control system includes main valve 2 and sub-valve 6; The multi-spray unit includes a downward-sloping spray pipe 7, an upward-sloping spray pipe 8, a horizontal spray pipe 9, and a downward-sloping spray pipe 10; The reflective heat-concentrating spray head includes a reflective heat-concentrating cover 11, a heat-sensitive tube 13, and a spray water pipe 15; The main valve 2 is fixedly connected to the front end of the main water supply pipe 1. The main valve 2 is a fire gate valve ZS45T-16. It serves as the switch for the main water circuit of the system. Under normal conditions, it is kept open to ensure rapid water supply in case of fire. During maintenance or repair, it is closed to cut off the water supply to the main water supply pipe 1 and prevent water leakage. The rated pressure of 1.6MPa is higher than the conventional fire water pressure of buildings, which can cope with water pressure fluctuations and ensure system stability. The cast iron material is wear-resistant and anti-aging, and is suitable for long-term use. The main valve 2 is equipped with a valve operating rod 3, which is a special operating rod for the ZS45T-16 gate valve. It is used to manually operate the opening and closing of the main valve 2, which is convenient for daily maintenance by staff. The chrome plating treatment on the surface can effectively prevent rust and avoid operation jamming due to rust, ensuring that the valve can be opened and closed quickly in an emergency. A plug 4 is fixedly connected to the end of the water supply main pipe 1. Several multi-spray unit connection ports are evenly arranged on the water supply main pipe 1. Several U-shaped pipe clamps 5 are fixedly connected to the main water supply pipe 1. The U-shaped pipe clamps 5 are evenly distributed on the main water supply pipe 1 and the number varies according to the length of the main water supply pipe 1. The lower spray pipe 10 is fixedly connected to the bottom of the water supply main pipe 1. Four horizontal spray pipes 9 are fixedly connected to both sides of the middle part of the water supply main pipe 1. The upward-sloping spray pipe 8 is fixedly connected to the left side of the front end and the right side of the rear end of the water supply main pipe 1. The downward-sloping spray pipe 7 is fixedly connected to the right side of the front end and the left side of the rear end of the water supply main pipe 1. The downward-sloping spray pipe 7, the upward-sloping spray pipe 8, the horizontal spray pipe 9, and the lower spray pipe 10 form a three-dimensional spherical spray range. Several sub-valves 6 are fixedly connected to the front end of the downward-sloping sprinkler pipe 7, the upward-sloping sprinkler pipe 8, the horizontal sprinkler pipe 9, and the downward sprinkler pipe 10. The sub-valves 6 are fire ball valves Q11F-16DN25, which control the water flow of a single sprinkler unit. The brass material has both rust resistance and sealing performance, which can prevent water leakage caused by long-term use. The full-bore design can reduce water flow resistance, ensure that the sprinkler unit receives sufficient flow, and improve fire extinguishing efficiency. A solenoid valve 16 is fixedly connected to the sub-valves 6. The solenoid valve 16 is a fire-specific solenoid valve 2W-250-25, which is linked with the sub-valves 6 and is the core component for realizing directional sprinkler. When a fire is detected and triggered, the solenoid valve 16 will quickly receive the signal and drive the corresponding sub-valves 6 to open, allowing water to enter the sprinkler unit in the direction of the fire. The solenoid valves in other directions remain closed to avoid water waste. The response time of ≤0.5s can ensure rapid water supply in the early stage of a fire, buying time for fire extinguishing. Several spray pipes 15 are fixedly connected to the output ends of the inclined downward spray pipe 7, the inclined upward spray pipe 8, the horizontal spray pipe 9, and the downward spray pipe 10. A spray head bracket 14 is fixedly connected to the spray pipe 15. A heat-sensitive tube 13 is fixedly connected inside the spray head bracket 14. A reflective heat-concentrating cover 11 is fixedly connected to the top of the spray head bracket 14. A splash plate 12 is fixedly connected to the bottom of the spray head bracket 14.

[0021] Working principle: When a fire occurs in the protected area, the heat radiation generated by the flame spreads to the surroundings. The reflective heat-concentrating cover 11 of each spray unit focuses the heat radiation from different directions onto the heat-sensitive tube 13, thereby increasing the heat intensity received by the heat-sensitive tube 13 by 3-5 times and shortening the thermal response time. Because the reflective heat-concentrating cover 11 is aligned with the direction of the spray unit, it is only sensitive to heat radiation in the corresponding direction, thus avoiding accidental triggering of environmental heat sources in non-fire areas. When the heat-sensitive tube 13 in the direction of the fire is triggered by high temperature, the state change of the heat-sensitive tube 13 is transmitted to the corresponding sub-valve 6 through an electrical signal. The sub-valve 6 is quickly opened under the drive of the solenoid valve 16, allowing water to enter the sprinkler unit in the direction of the fire only. The main valve 2 is normally closed via the valve operating rod 3, and is opened by default in case of fire, ensuring that the water flow from the main water supply pipe 1 can enter the target sprinkler unit through the opened sub-valve 6. After the water flow enters the corresponding sprinkler unit through the directional opening sub-valve 6, it achieves three-dimensional fire suppression through the following path. Fire water in the main water supply pipe 1 is diverted through sub-valve 6 to the inclined downward sprinkler pipe 7, inclined upward sprinkler pipe 8, horizontal sprinkler pipe 9 or downward sprinkler pipe 10, and then transported to the sprinkler head through sprinkler water pipe 15. The angle design of different sprinkler pipes determines the direction of water flow - the lower sprinkler pipe 10 covers the area directly below, the horizontal sprinkler pipe 9 covers the left and right / front and back middle space, the upward-sloping sprinkler pipe 8 covers the ceiling or the area above, and the downward-sloping sprinkler pipe 7 covers the wall and ground transition area downwards, which together form a spherical fire extinguishing range. Water flows through the splash plate 12 and is dispersed into water droplets in the appropriate direction. For example, the splash plate of the horizontal sprinkler pipe 9 spreads the water flow into a fan shape to cover the wall, while the splash plate of the lower sprinkler pipe 10 forms an umbrella shape to cover the ground, thereby improving the fire extinguishing efficiency. After the fire is extinguished, close the main valve 2, cut off the water flow from the main water supply pipe 1, replace the triggering thermal tube 13 and the sealing components of the corresponding sub-valve 6, reset the control signal of the solenoid valve 16, ensure that the sub-valve 6 returns to the closed state, open the main valve 2, and discharge the air in the pipeline through the plug 4 to complete the system reset.

[0022] Structural Description: Water supply main pipe 1: As the core water supply channel of the entire sprinkler head system, it is used to connect the main fire protection pipeline of the building to each multi-sprinkler unit, and to supply fire water to the system. At the same time, the multi-sprinkler unit connection ports are evenly set on its pipe body, providing a foundation for the installation of multi-sprinkler units. It can supply water to all sprinkler units in a centralized and stable manner, ensuring that the water pressure of each unit is balanced. Meanwhile, the uniform connection port layout facilitates the installation of multi-sprinkler units in the preset position, laying the foundation for the subsequent formation of a three-dimensional spherical sprinkler range. Main valve 2: As the control switch for the main water circuit of the system, it is installed at the front end of the main water supply pipe 1. It adopts the structure of a fire gate valve. Under normal conditions, it is kept open to ensure that fire water can quickly enter the main water supply pipe 1 in case of fire. When it is closed for maintenance or repair, it can cut off the water supply and prevent water leakage. Its specific gate valve structure and rated pressure design can cope with the fluctuation of building fire water pressure and ensure the stability of the system water supply. Moreover, the cast iron material is wear-resistant and anti-aging, and can be used reliably for a long time, reducing the trouble of frequent replacement. Valve operating lever 3: This is the manual operating component of the main valve 2. It is set up in conjunction with the main valve 2. The operator can easily control the opening and closing of the main valve 2 by manual operation, which is convenient for daily maintenance. The anti-rust treatment on the surface can prevent the operation from being stuck due to rust, and ensure that the main valve 2 can be quickly opened and closed in an emergency, so as not to delay the opportunity to deal with the fire. Plug 4: It is fixedly connected to the end of the water supply main pipe 1 to seal the water supply main pipe 1 and prevent the water in the water supply main pipe 1 from overflowing from the end. At the same time, during system maintenance, the plug 4 can be removed to discharge air or impurities in the pipe, ensuring the cleanliness of the inside of the pipe and maintaining the smooth flow of water. U-shaped pipe clamps 5: are fixedly connected to the main water supply pipe 1 and distributed along the length of the main water supply pipe 1. They can stably fix the main water supply pipe 1 on the preset support to prevent the main water supply pipe 1 from shifting or shaking due to water pressure impact or external collision, and ensure that the main water supply pipe 1 remains in a horizontal and stable state, providing a guarantee for the precise spraying of multiple spray units. Moreover, their number can be adjusted according to the length of the main water supply pipe 1, which can adapt to the installation requirements of different lengths of main water supply pipe 1 and enhance applicability. Sub-valve 6: It is fixedly connected to the front end of the inclined downward sprinkler pipe 7, the inclined upward sprinkler pipe 8, the horizontal sprinkler pipe 9, and the downward sprinkler pipe 10 respectively. It adopts the fire ball valve structure and can control the water flow of the corresponding sprinkler unit individually to achieve directional spraying. The use of brass material makes it both rust-proof and sealing, avoiding water leakage problems after long-term use. The full-bore design can reduce water flow resistance, ensure that the corresponding sprinkler unit receives sufficient flow, and improve fire extinguishing efficiency. Slanted downward sprinkler pipe 7: Fixedly connected to the front right side and rear left side of the main water supply pipe 1, serving as a water delivery channel to transport water to the corresponding reflective heat-concentrating hood sprinkler head. Its specific installation position and angle enable the water to spray downwards, covering the transition area between the wall and the ground downwards. In conjunction with other sprinkler pipes, it forms a three-dimensional spherical spray range, filling the spray blind spot in this area and improving the overall fire extinguishing coverage effect. 8. Upward-sloping sprinkler pipe: It is fixedly connected to the left front end and the right rear end of the main water supply pipe 1. It is used to transport the water flow in the main water supply pipe 1 to the corresponding reflective heat-concentrating sprinkler head. Through a specific installation angle, it can guide the water flow to spray upwards and downwards, covering the area above the ceiling or space. This solves the problem that traditional sprinkler heads cannot cover the area above. It works in conjunction with other sprinkler pipes to achieve three-dimensional fire suppression and eliminate the hidden danger of fire spreading in the area above. Horizontal sprinkler pipe 9: Fixedly connected to both sides of the middle of the water supply main pipe 1, there are four in total. It is responsible for delivering water to the corresponding reflective heat-concentrating hood sprinkler head. Its horizontal installation angle allows the water to spray in a horizontal direction, covering the left and right or front and back middle layer areas of the space, filling the spray gaps in the middle layer space. In conjunction with sprinkler pipes in other directions, it further improves the three-dimensional spherical spray range and ensures that fires in the middle layer area can be extinguished in time. Lower spray pipe 10: Fixedly connected to the bottom of the main water supply pipe 1, serving as a water supply channel connecting the main water supply pipe 1 with the corresponding reflective heat-concentrating hood spray head, guiding water flow to spray directly downwards, covering the area directly below the main water supply pipe 1. This area is easily covered by traditional spray heads but requires stable coverage. This setting ensures sufficient water flow in this area, forming a three-dimensional spherical spray range together with other spray pipes, improving the overall fire extinguishing reliability. Reflective heat-concentrating cover 11: Fixedly connected to the top of the sprinkler head bracket 14, covering the heat-sensitive tube 13, it can focus the heat radiation of the fire from different directions onto the heat-sensitive tube 13, enhance the heat intensity received by the heat-sensitive tube 13, shorten the heat response time, and enable the system to detect the fire faster. Moreover, it is aligned with the direction of the sprinkler unit and is only sensitive to heat radiation in the corresponding direction, which can avoid the environmental heat source in non-fire areas from falsely triggering the system and improve the detection accuracy. Water splash plate 12: It is fixedly connected to the bottom of the sprinkler head bracket 14. It is designed with a specific shape according to the spray direction of the corresponding sprinkler pipe. It can disperse the water flow delivered by the sprinkler pipe 15 into water splashes that are suitable for the spray direction. For example, the water flow of the horizontal sprinkler pipe 9 can be spread into a fan shape to cover the wall, and the water flow of the lower sprinkler pipe 10 can form an umbrella shape to cover the ground. This increases the contact area between the water flow and the fire, improves the fire extinguishing efficiency, and ensures that fires in different directions can be effectively extinguished. Thermosensitive tube 13: Fixedly connected inside the sprinkler head bracket 14, it is the fire detection element of the system. It can accurately receive the heat radiation focused by the reflective heat-concentrating cover 11. When the temperature reaches the set value, it triggers the system to open the corresponding sub-valve 6 to spray water. It is installed inside the bracket to avoid damage from minor external collisions. At the same time, it can quickly sense changes in heat to ensure that the fire is detected in time and fire extinguishing actions are triggered. Spray head bracket 14: It is fixedly connected to the spray water pipe 15 and is used to fix the heat-sensitive tube 13, the reflective heat-concentrating cover 11 and the splash plate 12. It can stably and accurately fix the three key components in the preset position, ensuring that the focus of the reflective heat-concentrating cover 11 is aligned with the heat-sensitive tube 13, and the splash plate 12 can effectively disperse the water flow, ensuring that the components work together, while providing support for the components and preventing the components from shifting and affecting the normal operation of the system. Spray pipe 15: It is fixedly connected to the output end of the inclined lower spray pipe 7, the inclined upper spray pipe 8, the horizontal spray pipe 9, and the lower spray pipe 10. It connects the corresponding spray unit and the reflective heat-concentrating hood spray head. It can smoothly guide the water flow delivered by each spray unit to the reflective heat-concentrating hood spray head, providing a channel for subsequent water flow dispersion and spraying, ensuring that the water flow can smoothly reach the fire extinguishing area. At the same time, its connecting function can make the reflective heat-concentrating hood spray head and the spray unit form a stable whole, improving the structural stability of the system. Electromagnetic valve 16: Fixedly connected to sub-valve 6 and linked with thermal tube 13. When thermal tube 13 is triggered, it can quickly receive the signal and drive the corresponding sub-valve 6 to open, realizing directional spraying. It allows water to flow only into the spray unit in the direction of the fire, avoiding water waste. Its fast response time can ensure timely water supply in the early stage of the fire, buy valuable time for fire fighting, and improve the timeliness and effectiveness of the system's fire fighting.
