Description

Technical Field

[0001] The present application belongs to the field of fire fighting equipment, and more specifically, to a smart sprinkler head with a dual-start trigger temperature sensing device. Background Art

[0002] Fire sprinkler nozzles are an indispensable part of the fire safety system. They can be quickly activated when a fire occurs, release fire extinguishing agents to control the spread of the fire, and provide valuable time for personnel evacuation and fire fighting and rescue. With the advancement of technology and the improvement of fire safety needs, the design and technology of fire sprinkler nozzles are also constantly innovating and developing.

[0003] Traditional fire sprinkler heads for buildings mainly rely on the induction temperature of glass balls or fusible alloy elements to start spraying water, and cannot be linked with fire alarm systems. This method has problems such as slow response speed and high false alarm rate, and cannot achieve extremely fast response to fires. Therefore, it is necessary to solve the above technical problems. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a smart sprinkler nozzle with a dual-start trigger temperature sensing device to solve the technical problems in the prior art that fire sprinkler nozzles do not respond in time and cannot be linked with the fire alarm system.

[0005] To achieve the above purpose, the technical solution adopted in this application is:

[0006] Provided is a smart sprinkler head with a dual-start trigger temperature sensing device, comprising:

[0007] A body, forming a water outlet and a connection end connected to the water outlet;

[0008] A screw, threadedly connected to the body, with the tip of the screw facing the water outlet;

[0009] A support assembly, comprising a straight support and a plug and a lever support abutting at both ends of the straight support, wherein the plug blocks the water outlet through the straight support, and a side of the lever support facing away from the straight support abuts against the tip of the screw, and the straight support and the screw are eccentrically arranged at their respective abutment points with the lever support;

[0010] A pull plate, comprising a first half piece and a second half piece connected by a fusible alloy, wherein the first half piece is connected to the straight support, and the second half piece is connected to the lever support;

[0011] The diaphragm type electric heater is bonded to the pull plate in the connection area between the first half sheet and the second half sheet and is electrically connected to the fire control system.

[0012] Optionally, the support assembly further comprises a spring abutting between the body and the plug, wherein the spring is pre-deformed and has a rebound direction perpendicular to the straight support.

[0013] Optionally, the plug forms a first flange and a second flange that are spaced apart, and a portion of the spring that abuts against the plug is accommodated in a space formed by the first flange and the second flange.

[0014] Optionally, the plug abuts against the straight support through the second flange, and the radius of the second flange is smaller than the radius of the first flange.

[0015] Optionally, a guide rail is formed on the main body and abuts against the outer circular surfaces at both ends of the spring, and the guide rail is parallel to the straight support.

[0016] Optionally, the pull plate is provided with a slot for the straight support and the lever support to pass through, the straight support is provided with a protrusion for limiting the first half piece, and the lever support is provided with a slot for limiting the second half piece.

[0017] Optionally, the pull plate further includes reinforcement sheets arranged on both sides of the notch.

[0018] Optionally, at least a portion of the first half sheet and the second half sheet are overlapped, and a circular hole is correspondingly provided at a position where the first half sheet and the second half sheet overlap.

[0019] Optionally, the smart sprinkler head with a dual-start trigger temperature sensing device also includes a splash plate connected to the main body and facing the water outlet.

[0020] Optionally, the diaphragm type electric heater comprises a heating wire which is heat-sealed and arranged in a curve between two layers of polyimide film, the heating wire is connected to an electrode, the heating wire has a thickness of 0.05 mm and a width of 0.69 mm, and the thickness of the polyimide film is not greater than 0.08 mm.

[0021] The beneficial effect of the smart sprinkler with a dual-start trigger temperature sensing device provided by the present application is that: compared with the prior art, one end of the straight support in the present application abuts against the plug and blocks the plug at the water outlet set on the body, and the other end abuts against the lever support. Since the side of the lever support facing away from the straight support abuts against the tip of the screw and the straight support and the screw are eccentrically arranged at the abutment with the lever support, when the fusible alloy between the first half piece connected to the straight support and the second half piece connected to the lever support melts, the lever support can be turned over and the straight support loses its support for the plug, so that the plug is separated from the water outlet and the water outlet is quickly opened, which significantly shortens the response time of the smart sprinkler with a dual-start trigger temperature sensing device provided by the present application to fire, which is far superior to the prior art.

[0022] In addition, the smart sprinkler nozzle with a dual-start trigger temperature sensing device provided in the present application can realize active heating of the pull plate. Therefore, the smart sprinkler nozzle provided in the present application can intelligently adjust the fire sprinklers in different positions to actively spray water according to the size and spread of the fire, thereby improving the fire extinguishing efficiency.

[0034] Please also read Figures 1 to 5 Now, a smart sprinkler head with a dual-start trigger temperature sensing device provided in an embodiment of the present application is described. The smart sprinkler head with a dual-start trigger temperature sensing device includes a body 101 , a screw 104 , a support assembly and a pull plate 108 .

[0035] Among them, the body 101 forms a water outlet 102 and a connecting end 103 connected to the water outlet 102, and the connecting end 103 can be used to connect with a fire-fighting pipe so that the water outlet 102 is used to connect to an external water supply pipe. It can be understood that a thread for installation and fixing can be provided on the connecting end 103. The screw 104 is threadedly connected to the body 101, and the tip of the screw 104 is directly opposite to the water outlet 102. The support assembly includes a straight support 105 and a plug 106 and a lever support 107 abutting against both ends of the straight support 105. The plug 106 blocks the water outlet 102 through the straight support 105. In other embodiments of the present application, in order to increase the sealing performance between the plug 106 and the water outlet 102, a sealing ring can also be provided on one side of the plug 106 for blocking the water outlet 102, which has a better sealing effect, which will not be repeated here.

[0036] The side of the lever support 107 facing away from the straight support 105 abuts against the tip of the screw 104, and the straight support 105 and the screw 104 are eccentrically arranged at the abutment points with the lever support 107. The pull plate 108 includes a first half sheet 110 and a second half sheet 111 connected by a fusible alloy 109, wherein the first half sheet 110 is connected to the straight support 105, and the second half sheet 111 is connected to the lever support 107. In this embodiment, the fusible alloy 109 can melt rapidly when the temperature rises, so that the first half sheet 110 and the second half sheet 111 are quickly separated; wherein the diaphragm type electric heater 122 is bonded to the pull plate 108 and electrically connected to the fire control system, and preferably, the diaphragm type electric heater 122 is bonded to the connection area between the first half sheet 110 and the second half sheet 111.

[0037] According to the structure provided in this embodiment, one end of the straight support 105 abuts against the plug 106 and blocks the plug 106 at the water outlet 102 provided on the body 101 , and the other end abuts against the lever support 107 . Since the side of the lever support 107 facing away from the straight support 105 abuts against the tip of the screw 104 and the straight support 105 and the screw 104 are eccentrically arranged at the abutment points with the lever support 107, it can be understood that the abutment point of the screw 104 and the lever support 107 is farther away from the connection point between the second half piece 111 and the lever support 107 than the abutment point between the straight support 105 and the lever support 107. Therefore, when the fusible alloy 109 between the first half piece 110 connected to the straight support 105 and the second half piece 111 connected to the lever support 107 melts, the lever support 107 can be flipped and the straight support 105 can lose its support for the plug 106, thereby making the plug 106 detached from the water outlet 102 and realizing the rapid opening of the water outlet 102, which significantly shortens the response time of the smart sprinkler with a dual-start trigger temperature sensing device provided in the present application to fire, which is far superior to the prior art.

[0038] At the same time, according to the above structure provided in the present embodiment, since the diaphragm electric heater 122 in the present embodiment can actively heat the pull plate 108 and separate the first half sheet 110 and the second half sheet 111 so that the temperature sensing device is triggered and the sprinkler is started; therefore, the smart sprinkler provided in the present embodiment can actively start the fire sprinkler nozzles at different positions to actively spray water according to the size and spread of the fire under the control of the fire control system, thereby further improving the fire extinguishing efficiency, which is far superior to the existing technology.

[0039] In another embodiment of the present application, please refer to Figures 1 to 5 The support assembly further includes a spring 112 abutting between the body 101 and the plug 106, the spring 112 being pre-deformed and having a rebound direction perpendicular to the straight support 105. According to the above structure provided in this embodiment, the spring 112 can quickly bounce the plug 106 away from the water outlet 102 after the plug 106 loses the supporting force of the straight support 105, thereby further shortening the response time of the smart sprinkler with a dual-start trigger temperature sensing device provided in this embodiment to a fire.

[0040] In another embodiment of the present application, please refer to Figures 1 to 5 , the plug 106 forms a first flange 113 and a second flange 114 which are spaced apart, and the portion of the spring 112 abutting against the plug 106 is accommodated in the space formed by the first flange 113 and the second flange 114. According to the above structure provided in this embodiment, the first flange 113 and the second flange 114 can restrict the position of the spring 112 to a certain extent, so that it can be stabilized in a fixed position, which is conducive to enabling the spring 112 to maintain rapid response for a longer period of time.

[0041] In another embodiment of the present application, please refer to Figures 1 to 5 , the plug 106 is abutted against the straight support 105 through the second flange 114, and the radius of the second flange 114 is smaller than the radius of the first flange 113. According to the above structure provided in this embodiment, since the plug 106 is abutted against the straight support 105 through the second flange 114 and the second flange 114 with a smaller radius can have a smaller rotational torque, when the straight support 105 loses support for the second flange 114, it is beneficial for the plug 106 to quickly flip and detach from the water outlet 102, thereby further shortening the response time of the smart sprinkler with a dual-start trigger temperature sensing device provided in this embodiment to the fire. In addition, since the radius of the second flange 114 is small, the spring 112 is installed in the gap between the first flange 113 and the second flange 114 through a small elastic deformation, which is beneficial to avoid the spring 112 being in a state of high elastic restoring force for a long time and causing easy failure, and ensure that the smart sprinkler with a dual-start trigger temperature sensing device provided in this embodiment can be in a stable duty state for a long time.

[0042] In another embodiment of the present application, please refer to Figures 1 to 5 , a guide rail 115 is formed on the body 101 to abut against the outer circumferential surfaces at both ends of the spring 112, and the guide rail 115 is parallel to the straight support 105. According to the above structure provided in this embodiment, the guide rail 115 can be used to guide the spring 112. In this way, when the straight support 105 blocks the plug 106 at the water outlet 102, the spring 112 can be guided by the guide rail 115 and rise with the plug 106, which is conducive to the faster installation of the smart sprinkler with a dual-start trigger temperature sensing device provided in this embodiment.

[0043] In another embodiment of the present application, please refer to Figures 1 to 5 The pull plate 108 is provided with a notch 116 for the straight support 105 and the lever support 107 to pass through, the straight support 105 is provided with a protrusion 117 for limiting the first half piece 110, and the lever support 107 is provided with a slot 118 for limiting the second half piece 111. According to the above structure provided in this embodiment, the pull plate 108 is convenient to maintain a stable connection relationship with the straight support 105 and the lever support 107 by being sleeved on the straight support 105 and the lever support 107, which is convenient to improve the structural stability of the smart sprinkler with a dual-start trigger temperature sensing device provided in this embodiment when on fire duty.

[0044] In another embodiment of the present application, please refer to Figures 1 to 5 The pull plate 108 also includes reinforcing plates 119 disposed on both sides of the notch 116. According to the above structure provided in this embodiment, the reinforcing plates disposed on both sides of the notch 116 are conducive to improving the structural strength of the pull plate 108 in this embodiment, thereby further improving the structural stability of the smart sprinkler head with a dual-start trigger temperature sensing device provided in this embodiment when on fire duty.

[0045] In another embodiment of the present application, please refer to Figures 1 to 5 The first half sheet 110 and the second half sheet 111 are at least partially overlapped, and a circular hole 120 is correspondingly provided at the position where the first half sheet 110 and the second half sheet 111 overlap. According to the above structure provided in this embodiment, the first half sheet 110 and the second half sheet 111 are provided with the circular hole 120, and when welding with fusible alloy, the fixture positioning guide rod can be passed through the circular hole 120 to achieve rapid positioning, which is conducive to improving production efficiency.

[0046] In another embodiment of the present application, please refer to Figures 1 to 5The smart sprinkler head with dual-start trigger temperature sensing device also includes a splash plate 121 connected to the body 101 and facing the water outlet 102. According to the above structure provided in this embodiment, the splash plate 121 connected to the body 101 can effectively expand the splash range of the smart sprinkler head with dual-start trigger temperature sensing device provided in this embodiment, and achieve a better fire extinguishing effect.

[0047] In another embodiment of the present application, please also refer to Figure 1 and Figure 5 The diaphragm electric heater 122 includes a heating wire 123 that is heat-sealed and arranged in a curve between two layers of polyimide film 124. The heating wire 123 is connected to an electrode 125. The heating wire has a thickness of 0.05 mm and a width of 0.69 mm. The thickness of the polyimide film 124 is not more than 0.08 mm. It is connected to the circuit of the fire control system through the electrode 125. It has a fast heating speed when triggered, which is beneficial to the timely response of the sprinkler head and has a good self-protection effect. It can effectively improve the stability of the sprinkler head during cleaning and defense duty and the reliability of rapid triggering when a fire occurs.

[0048] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
