[0002] Fire sprinklers are a vital component of automatic sprinkler systems, and they play a vital role when a fire occurs. As a key device in the modern fire safety system, fire sprinklers are designed to quickly respond to the initial stage of a fire, effectively curb the spread of fire, and protect the safety of people and property.

[0003] Traditional fire sprinklers usually use fusible materials or glass balls as temperature sensors and trigger mechanisms, that is, they are triggered when the temperature reaches a certain threshold, thereby releasing water. Sprinklers using this method are passive sprinklers, which have the disadvantage of being triggered only when the impact of the fire expands to a certain range after the fire occurs. There are also active trigger sprinklers that use electric heating, but their response sensitivity is low, and they often have the disadvantages of being large in size and complex in structure.

[0004] Therefore, it is necessary to solve the above technical problems. Summary of the invention

[0035] Please also read Figures 1 to 5 Now, an active start glass ball sprinkler provided in the embodiment of the present application is described. The active start glass ball sprinkler comprises a frame 101, a support mechanism and a start mechanism. Among them:

[0036] The frame 101 has a connection end 102 for connecting a fire-fighting pipe, and the connection end 102 forms a water outlet channel 103. The supporting mechanism includes a stopper 104, a glass ball 105, and a tightening screw 106 threadedly connected to the frame 101 in sequence. The stopper 104 abuts against the frame 101 through the glass ball 105 and the tightening screw 106 and is used to close the water outlet channel 103. The starting mechanism includes a guide 107 connected to the stopper 104 and an impact pin 108 movably connected to the guide 107. The glass ball 105 is located on the moving path of the impact pin 108 relative to the guide 107 and can be broken by the impact pin 108. The starting mechanism also includes a solid gas generating agent 109 that can be electrically triggered and generate impact gas. The solid gas generating agent 109 is arranged on the side of the impact pin 108 away from the glass ball 105 and is used to drive the impact pin 108 to rush towards the glass ball 105 after triggering. It can be understood that the active-start glass ball sprinkler provided in this embodiment also includes a splash plate and other structures commonly used in the art, which will not be described in detail here.

[0037] According to the above structure provided in this embodiment, a support mechanism and a pneumatic mechanism are provided in the active start type glass ball sprinkler provided in this embodiment, wherein the stopper 104 in the support mechanism is supported by the glass ball 105 and the tightening screw 106 and blocks the water outlet channel 103. When the solid gas generating agent 109 in the starting mechanism is triggered, its impact gas can drive the impact pin 108 to move quickly relative to the guide member 107 and break the glass ball 105, so that the stopper 104 that loses support can be flushed away by the water flow in the water outlet channel 103 and the active start type glass ball sprinkler provided in this application can be used for fire fighting. Since the impact gas generated by the solid gas generating agent 109 in this embodiment can make the impact pin 108 break the glass ball 105 in a very short time, the response speed of the active start type glass ball sprinkler provided in this embodiment can be significantly improved, which is far superior to the prior art. Of course, the glass ball 105 provided in the present embodiment can also be set to have a temperature threshold for automatic rupture, so that when a fire occurs, the actively started glass ball sprinkler provided in the present embodiment can also respond automatically, thereby achieving a better fire extinguishing effect; at the same time, by controlling the electrical connection between the wire 123 and the fire protection system, the sprinkler can be triggered in advance in front of the path where the fire spreads to spray water preventively, thereby effectively preventing the fire from spreading; and, the guide member 107 and the stop head 104 are designed as an integrated whole, thereby effectively reducing the number of components and the complexity of the entire sprinkler. When the sprinkler is triggered, the guide member 107 and the stop head 104 can simultaneously detach from the water outlet area of ​​the water outlet channel 103, thereby avoiding blocking the water flow and improving reliability and fire extinguishing efficiency.

[0038] In another embodiment of the present application, please refer to Figures 1 to 5, the guide member 107 forms a receiving hole 110 and a guide hole 111 that are interconnected, at least a portion of the impact pin 108 and the solid gas generating agent 109 are disposed in the receiving hole 110, and the impact pin 108 also has another portion that extends into the guide hole 111 and can be provided with movement guidance by the guide hole 111. According to the above structure provided in this embodiment, on the one hand, the solid gas generating agent 109 disposed in the receiving hole 110 can provide a directional instantaneous impact force for the impact pin 108, and on the other hand, the guide hole 111 can provide a more stable guidance for the movement of the impact pin 108, so that the impact pin 108 provided in this embodiment can rush toward the glass ball 105 more quickly and stably and break the glass ball 105, which is conducive to further improving the response speed of the active start type glass ball sprinkler provided in this embodiment.

[0039] In another embodiment of the present application, please refer to Figures 1 to 5 The starting mechanism further includes a sealing gasket 112 disposed in the receiving hole 110, the sealing gasket 112 abuts against the side of the solid gas generating agent 109 away from the impact pin 108 and is sealed with the guide member 107 to form a side wall of the receiving hole 110, and the sealing gasket 112 is also provided with a wire hole 113 for the control wire 123 of the solid gas generating agent 109 to pass through; the control wire 123 is electrically connected to the fire control system. According to the above structure provided in this embodiment, the sealing gasket 112 disposed on the side of the solid gas generating agent 109 away from the impact pin 108 can make the impact gas generated after the solid gas generating agent 109 is triggered act on the impact pin 108 more fully, thereby enabling the impact pin 108 to rush toward the glass ball 105 more quickly and stably and break the glass ball 105, which is conducive to further improving the response speed of the active start type glass ball sprinkler provided in this embodiment.

[0040] In another embodiment of the present application, please refer to Figures 1 to 5 The starting mechanism further includes a screw sleeve 114 threadedly connected to the guide member 107, and the sealing gasket 112 is clamped between the screw sleeve 114 and the solid gas generating agent 109. According to the above structure provided in this embodiment, the screw sleeve 114 threadedly connected to the guide member 107 can form a stable support for the sealing gasket 112, which can effectively prevent the sealing gasket 112 from moving inside the receiving hole 110 after being subjected to the impact gas triggered by the solid gas generating agent 109, thereby avoiding the problem of the impact force of the impact gas triggered by the solid gas generating agent 109 being reduced due to the movement of the sealing gasket 112, thereby enabling the impact pin 108 to rush toward the glass ball 105 more quickly and stably and break the glass ball 105, which is conducive to further improving the response speed of the active start type glass ball sprinkler provided in this embodiment.

[0041] In another embodiment of the present application, please refer to Figures 1 to 5The starting mechanism further includes a sealing sheet 115 that can be punctured by the impact pin 108. The sealing sheet 115 is connected to the guide member 107 and is used to close the side port of the guide hole 111 away from the receiving hole 110. According to the above structure provided in this embodiment, the sealing sheet 115 used to close the guide hole 111 can prevent foreign impurities from entering the guide hole 111 and the receiving hole 110, which is conducive to the long-term and stable use of the active start type glass ball sprinkler provided in this embodiment. Optionally, the sealing sheet 115 in this embodiment can be selected as a structure such as an aluminum film or a plastic sheet.

[0042] In another embodiment of the present application, please refer to Figures 1 to 5 The side surface of the stopper 104 facing the glass ball 105 forms a receiving cavity 116, and at least a part of the glass ball 105 is received in the receiving cavity 116. According to the above structure provided in this embodiment, the glass ball 105 abuts against the receiving cavity 116, so that the glass ball 105 abuts against the stopper 104 more stably, which is conducive to the long-term and stable use of the active start glass ball sprinkler provided in this embodiment.

[0043] In another embodiment of the present application, please refer to Figures 1 to 5 , a boss 117 coaxial with the water outlet channel 103 is formed on the side of the stopper 104 facing the water outlet channel 103, and an inclined surface 118 inclined relative to its own central axis is formed on the surface of the boss 117. According to the above structure provided in this embodiment, the inclined surface 118 formed on the surface of the boss 117 can enable the boss 117 to withstand the impact force of the water flow inclined relative to the water outlet channel 103, so that the stopper 104 can be turned over more quickly and leave the central axis of the water outlet channel 103 when it is flushed away by the water flow in the water outlet channel 103, which is conducive to the rapid discharge of water by the active start glass ball sprinkler provided in this embodiment and forming a good fire extinguishing effect.

[0044] In another embodiment of the present application, please refer to Figures 1 to 5 The stopper 104 forms a flange portion 119 for abutting against the frame 101, and the frame 101 forms a countersunk hole 120 for accommodating the flange portion 119. According to the above structure provided in this embodiment, since the flange portion 119 of the stopper 104 is accommodated in the countersunk hole 120 formed on the frame 101, the countersunk hole 120 can effectively limit the direction of the water outlet channel 103 of the stopper 104 from shaking relative to the frame 101, which is conducive to the active start glass ball sprinkler provided in this embodiment being able to be used stably for a long time during fire duty.

[0045] In another embodiment of the present application, please refer to Figures 1 to 5The flange 119 is used to form an end face annular groove 121 on the end face abutting against the frame 101. The support mechanism also includes a sealing ring 122 accommodated in the end face annular groove 121. The flange 119 is sealed and connected to the frame 101 through the sealing ring 122. According to the above structure provided in this embodiment, the flange 119 can form a more stable sealing connection with the frame 101 through the sealing ring 122 disposed in the end face annular groove 121, which is conducive to the long-term and stable use of the active start glass ball sprinkler provided in this embodiment.

[0046] In another embodiment of the present application, please refer to Figures 1 to 5 , the guide member 107 and the stopper 104 are integrally formed, and the centers of gravity of the guide member 107 and the stopper 104 are offset from each other in the horizontal direction. According to the above structure provided in this embodiment, the guide member 107 and the stopper 104 are integrally formed so that the center of gravity of the overall structure of the two can be further offset from the central axis of the water outlet channel 103, so that the stopper 104 can be turned over more quickly when it is flushed away by the water flow in the water outlet channel 103 and leave the water outlet area of ​​the water outlet channel 103 together with the guide member 107, which is conducive to the rapid discharge of water by the active start glass ball sprinkler provided in this embodiment and forming a good fire extinguishing effect.

[0047] The above description is only a preferred embodiment of the present application and is not intended to limit the present application.
