Abstract
Description
Technical Field
[0001] This application relates to the field of fire sprinkler technology, and in particular to a multi-angle adjustable rotary fire sprinkler. Background Technology
[0002] Fire sprinklers are key components of fire sprinkler systems and are widely used in building fire protection facilities. Their main function is to extinguish flames or control the spread of fire by spraying water when a fire occurs. With the acceleration of urbanization and the increasing complexity of building structures, higher requirements are placed on the performance and function of fire sprinklers to ensure effective fire suppression in various fire scenarios.
[0003] Traditional fire sprinklers typically employ a fixed structure, including pendant, upright, and sidewall types. These sprinklers are fixed to the water supply pipe via threaded connections. When the temperature-sensing element (such as a glass bulb) ruptures due to heat, water is ejected from the sprinkler to extinguish the fire.
[0004] While traditional fire sprinklers can meet firefighting needs to a certain extent, their fixed water spray direction limits their effectiveness in complex fire scenarios. They cannot flexibly adjust the spray direction according to the specific location of the fire source and changes in the fire intensity, thus reducing the practicality of fire sprinklers. Utility Model Content
[0005] The purpose of this application is to address the problem that traditional fire sprinklers cannot flexibly adjust the spray direction according to the specific location of the fire source and changes in the fire intensity, thus reducing the practicality of fire sprinklers. This application provides a multi-angle adjustable rotary fire sprinkler.
[0006] To achieve the above objectives, this application specifically adopts the following technical solution:
[0007] A multi-angle adjustable rotary fire sprinkler head includes a cross-head nozzle. One end of the cross-head nozzle has an annular groove, and a ring frame is rotatably fitted inside the annular groove. A polygonal fastening cap is fixedly connected to the middle section of the cross-head nozzle. A water guide plate is fixedly connected to the bottom of the ring frame at an angle. A fusible glass column is fixedly connected to one end of the water guide plate. A T-shaped plug is inserted into the inner bottom of the cross-head nozzle, and the bottom of the fusible glass column abuts against the T-shaped plug. A drive assembly for driving the ring frame to rotate is installed at one end of the polygonal fastening cap. A monitoring element for detecting fire sources is installed at one end of the cross-head nozzle.
[0008] By adopting the above technical solution and using the monitoring component and drive assembly in conjunction, the water guide plate can be driven to rotate towards the fire source based on the real-time fire source direction monitored by the monitoring component. After the fusible glass column bursts due to heat, the water flow can pass through the cross-head nozzle, rush to the top of the water guide plate, and rush towards the fire source along the guide direction of the water guide plate. This facilitates the automatic adjustment of the water flow impact direction according to the fire source direction, improving the fire extinguishing efficiency and practicality of the device.
[0009] Furthermore, the drive assembly includes a gear ring fixedly connected to the top of the ring frame, and an installation chamber is provided inside the polygonal fastening cap. A motor is fixedly connected inside the installation chamber, and the output end of the motor passes through the polygonal fastening cap and is fixedly connected to a gear that meshes with the gear ring.
[0010] By adopting the above technical solution and setting up the cooperation between the gear and the gear ring, it is easy to drive the gear ring and the gear to mesh by starting the motor, and drive the ring frame and the water guide plate to rotate, thereby realizing the adjustment of the orientation of the water guide plate and effectively improving the practicality of the device.
[0011] Furthermore, the monitoring component includes four thermal sensors that are uniformly fixedly connected to one end of the cross-head nozzle, and the thermal sensors are electrically connected to the motor.
[0012] By adopting the above technical solution and using a combination of thermal sensors and motors, the location of the fire source can be monitored in real time, effectively improving the accuracy of the device.
[0013] Furthermore, the inner wall of the installation chamber is fixedly connected with heat-insulating rock wool, and the motor is installed inside the heat-insulating rock wool.
[0014] By adopting the above technical solution and combining the heat-insulating rock wool with the installation chamber, the heat insulation of the motor is effectively improved.
[0015] Furthermore, one end of the T-shaped plug is provided with a groove, and the contact surface between the T-shaped plug and the cross-head nozzle is provided with multiple extrusion grooves evenly.
[0016] By adopting the above technical solution, and by setting up the column groove and the extrusion groove in combination, when the fusible glass column breaks, water can enter the extrusion groove and squeeze the T-shaped plug to deform and collapse into the column groove. This quickly releases the T-shaped plug from the contact surface of the cross-head nozzle, allowing the T-shaped plug to quickly detach from the cross-head nozzle, thus improving the practicality of the device.
[0017] Furthermore, the bottom of the fusible glass column passes through the water guide plate and is fixedly connected to a heat-conducting copper column.
[0018] By adopting the above technical solution and using the combination of thermally conductive copper pillars and fusible glass pillars, the thermal sensitivity of the fusible glass pillars is effectively improved.
[0019] Furthermore, a sealing rubber gasket is fixedly fitted at one end of the cross-head nozzle.
[0020] By adopting the above technical solution and using a sealing rubber gasket in conjunction with the cross-head nozzle, the sealing performance between the cross-head nozzle and the high-pressure water pipe joint is effectively improved.
[0021] Furthermore, the ring frame is configured as a ceramic heat insulation frame.
[0022] By adopting the above technical solution and setting up a ceramic heat insulation frame, the heat resistance and corrosion resistance of the ring frame are effectively improved, and the service life of the device is extended.
[0023] In summary, this application includes at least one of the following beneficial effects:
[0024] 1. By setting up the monitoring component and the drive assembly to work together, the water guide plate can be driven to rotate towards the fire source based on the real-time monitoring of the fire source direction. After the fusible glass column bursts due to heat, the water can pass through the cross-head nozzle, rush to the top of the water guide plate, and rush towards the fire source along the guide direction of the water guide plate. This allows the water flow to be automatically adjusted according to the direction of the fire source, improving the fire extinguishing efficiency and practicality of the device.
[0025] 2. By using the column groove and the extrusion groove in combination, water can easily enter the extrusion groove when the fusible glass column breaks, and squeeze the T-shaped plug to deform and collapse into the column groove. This quickly releases the T-shaped plug from the contact surface of the cross-head nozzle, allowing the T-shaped plug to quickly separate from the cross-head nozzle, thus improving the practicality of the device.

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0032] This application discloses a multi-angle adjustable rotary fire sprinkler head.
[0033] Reference Figures 1-3 A multi-angle adjustable rotary fire sprinkler head includes a cross-head nozzle 1, an annular groove 2 at one end of the cross-head nozzle 1, a ring frame 3 rotatably fitted inside the annular groove 2, a polygonal fastening cap 4 fixedly connected to the middle section of the cross-head nozzle 1, a water guide plate 5 fixedly connected to the bottom of the ring frame 3 at an incline, a fusible glass column 6 fixedly connected to one end of the water guide plate 5, a T-shaped plug 7 inserted into the bottom of the cross-head nozzle 1, the bottom of the fusible glass column 6 abutting against the T-shaped plug 7, a drive component for driving the ring frame 3 to rotate is installed at one end of the polygonal fastening cap 4, and a monitoring element for detecting fire source is installed at one end of the cross-head nozzle 1.
[0034] The drive assembly includes a toothed ring 8 fixedly connected to the top of the ring frame 3, an installation chamber 9 is provided inside the polygonal fastening cap 4, a motor 10 is fixedly connected inside the installation chamber 9, the output end of the motor 10 passes through the polygonal fastening cap 4 and is fixedly connected to a gear 11 that meshes with the toothed ring 8.
[0035] Furthermore, the monitoring component includes four thermal sensors 12 that are uniformly fixedly connected to one end of the cross-head nozzle 1, and the thermal sensors 12 are electrically connected to the motor 10.
[0036] Furthermore, a sealing rubber gasket 17 is fixedly fitted at one end of the cross-head nozzle 1.
[0037] In use, firstly, the cross-head nozzle 1 is connected to the high-pressure water pipe connector by rotating the cross-head nozzle 1, so that the cross-head nozzle 1 is connected to the high-pressure water supply pipe. At the same time, the cross-head nozzle 1 causes the sealing rubber gasket 17 to come into contact with the high-pressure water pipe connector. Utilizing the elastic properties of the sealing rubber gasket 17, the sealing rubber gasket 17 is deformed under force and fills the space between the cross-head nozzle 1 and the high-pressure water pipe connector, thereby improving the sealing performance between the cross-head nozzle 1 and the high-pressure water pipe connector.
[0038] Then, four thermal sensors 12 are set up to monitor the temperature changes around the cross-head nozzle 1 in real time. When a fire source appears in a certain direction and heats the fusible glass column 6, causing the liquid inside the fusible glass column 6 to expand and burst, the water flow inside the high-pressure water pipe pushes the T-shaped plug 7 out of the interior of the cross-head nozzle 1 and through the cross-head nozzle 1 to the top of the guide plate 5. At this time, the heat insulation rock wool 13 drives the gear 11 to rotate according to the monitoring data provided by the thermal sensor 12 in a certain direction, and makes the gear 11 mesh with the gear ring 8, so that the gear 11 drives the ring frame 3 and the guide plate 5 to rotate synchronously, thereby making the guide plate 5 rotate and face the direction of the fire source detected by the thermal sensor 12, so that the water flow along the direction of the guide plate 5 rushes towards the fire source and extinguishes the fire source. This facilitates the automatic adjustment of the water spray direction according to the direction of the fire source, improving the fire extinguishing accuracy and practicality of the device.
[0039] Reference Figures 1-3 The inner wall of the installation chamber 9 is fixedly connected with heat-insulating rock wool 13, and the motor 10 is installed inside the heat-insulating rock wool 13.
[0040] When in use, by setting up heat-insulating rock wool 13 to wrap and protect the motor 10, a heat-insulating protective layer is formed on the outside of the motor 10, which effectively improves the heat resistance of the motor 10.
[0041] Reference Figures 1-3 One end of the T-shaped plug 7 is provided with a column groove 14, and the contact surface between the T-shaped plug 7 and the cross screw nozzle 1 is provided with multiple extrusion grooves 15.
[0042] When in use, when the fusible glass column 6 is heated and cracks, releasing the resistance to the T-plug 7, water from the high-pressure water pipe passes through the cross-head nozzle 1 and comes into contact with the T-plug 7. This causes the water to embed into the squeezing groove 15 and squeeze the T-plug 7 into the column groove 14, causing it to contract and deform. This quickly releases the T-plug 7 from the connection surface of the cross-head nozzle 1, allowing the T-plug 7 to quickly detach from the interior of the cross-head nozzle 1, effectively improving the practicality of the device.
[0043] Reference Figure 1 and Figure 2 The bottom of the fusible glass column 6 passes through the water guide plate 5 and is fixedly connected to the heat-conducting copper column 16.
[0044] When in use, as the temperature rises, the heat-conducting copper column 16 heats up rapidly and quickly transfers the heat to the fusible glass column 6, thereby effectively improving the thermal sensitivity of the fusible glass column 6 and enhancing the practicality of the device.
[0045] Reference Figure 1 and Figure 2 The ring frame 3 is set as a ceramic heat insulation frame.
[0046] When in use, by setting the ring frame 3 as a ceramic heat insulation frame, the heat resistance and corrosion resistance of the ring frame 3 are effectively improved, and the service life of the device is extended.
[0047] The implementation principle of the multi-angle adjustable rotary fire sprinkler in this embodiment is as follows: First, the cross-head nozzle 1 is connected to the high-pressure water pipe joint by rotating the cross-head nozzle 1, so that the cross-head nozzle 1 is connected to the high-pressure water supply pipe. At the same time, the cross-head nozzle 1 causes the sealing rubber gasket 17 to come into contact with the high-pressure water pipe joint. The elastic properties of the sealing rubber gasket 17 are utilized to deform the sealing rubber gasket 17 under force and fill the space between the cross-head nozzle 1 and the high-pressure water pipe joint to improve the sealing performance between the cross-head nozzle 1 and the high-pressure water pipe joint.
[0048] Then, four thermal sensors 12 are set to monitor the temperature changes around the cross-head nozzle 1 in real time. When a fire source appears in a certain direction and heats the fusible glass column 6, causing the liquid inside the fusible glass column 6 to expand and burst, the resistance to the T-type plug 7 is released, allowing the water in the high-pressure water pipe to pass through the cross-head nozzle 1 and form resistance with the T-type plug 7. This causes the water flow to embed into the squeezing groove 15 and squeeze the T-type plug 7 into the column groove 14 to shrink and deform. This quickly releases the adhesion between the T-type plug 7 and the cross-head nozzle 1, allowing the T-type plug 7 to quickly detach from the interior of the cross-head nozzle 1 and pass through the cross-head nozzle 1 to the top of the guide plate 5.
[0049] At this time, the heat-insulating rock wool 13 drives the gear 11 to rotate according to the monitoring data provided by the thermal sensor 12 in a certain direction, and the gear 11 meshes with the gear ring 8, so that the gear 11 drives the ring frame 3 and the water guide plate 5 to rotate synchronously, thereby causing the water guide plate 5 to rotate and face the direction of the fire source detected by the thermal sensor 12, so that the water flow along the orientation of the water guide plate 5 rushes towards the fire source and extinguishes the fire source.
