Technical Field

[0001] The utility model relates to the technical field of fire detection, in particular to a high-reliability starting device for a fire extinguishing device. Background Art

[0002] The current fire extinguishing device activation methods mainly include electric start and thermal start. The electric start method relies on an external power supply to provide the starting current to the starter or starting structure, but there is a risk of power supply or fire extinguishing control system failure in actual use, especially when a fire occurs. On the other hand, the thermal start structure does not rely on an external power supply, but its components may be environmentally unfriendly and may not meet compliance requirements during transportation.

[0003] Based on the above problems, an electric starting structure that does not rely on an external power supply is required to ensure that the fire extinguishing device can be reliably started when a fire occurs. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a high-reliability starting device for a fire extinguishing device, which solves the problem in the prior art that the hot start structure does not rely on an external power supply, but its components may be environmentally unfriendly and may not meet compliance requirements during transportation.

[0005] The utility model discloses a high-reliability starting device for a fire extinguishing device, comprising a device body, a connecting assembly and a temperature sensing cable;

[0006] A plurality of through holes are provided on the same side of the device body, and a connecting component is provided in the through hole, and an electrode is provided inside the connecting component for connecting a temperature sensing cable;

[0007] An energy storage component is provided inside the device body;

[0008] One end of the temperature sensing cable is connected to the electrode, and the other end is connected to the energy storage component inside the device body.

[0009] As a further improvement of the present invention, the connection assembly includes N plug-in posts, one end of each plug-in post is provided with a plug-in interface which completely penetrates the plug-in post, and a threaded thread opening is provided on the outer side of each plug-in post.

[0010] As a further improvement of the utility model, the device body includes a shell, a base is provided on one side of the shell, a connection port is provided at the base, a threaded connection area is provided at the connection port, and the threaded connection area is adapted to the threaded thread port provided on the outer side of the plug-in column.

[0011] As a further improvement of the utility model, a temperature control switch is provided on the temperature sensing cable, the temperature control switch is connected in parallel with the temperature sensing cable, and a thermistor wire is wound around the outer side of the temperature control switch through a connecting piece.

[0012] As a further improvement of the utility model, a thermistor is provided on the temperature sensing cable, the thermistor is tightly fitted to the outer side of the temperature sensing cable, and both ends of the thermistor are wrapped around the connector to fix the thermistor.

[0013] As a further improvement of the present invention, the connecting member includes at least two ring bodies, and N winding protrusions are provided on the sides of the two ring bodies close to each other. A winding groove is provided on the outer side of the winding protrusion, and the winding groove is adapted to the thermal sensitive wire.

[0014] As a further improvement of the utility model, one of the plug posts is connected to an electrical device via a cable, and the other end of the cable is connected to an energy storage component provided inside the device body.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] The utility model uses the connection terminal and the controller to realize detection by thermistor and temperature sensing cable by separate connection when in use. Since thermistor will burn after reaching a predetermined temperature, and the temperature sensing cable will close without generating sparks after reaching a predetermined temperature, the two can be placed in different environments for detection. Thermistor itself cannot generate a closing signal to close the system and generate current, so it needs to be used in conjunction with a temperature control switch. The temperature control switch and the temperature sensing cable are connected in parallel, and any signal can energize the system. In addition, thermistor and the temperature sensing cable can be placed in a protection area to prevent one of the detection methods from failing. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] See also Figure 1-Figure 3 The current fire extinguishing device activation methods mainly include electric start and thermal start. The electric start method relies on an external power supply to provide the starting current to the starter or starting structure, but there is a risk of power supply or fire extinguishing control system failure in actual use, especially when a fire occurs. On the other hand, the thermal start structure does not rely on an external power supply, but its components may be environmentally unfriendly and may not meet compliance requirements during transportation.

[0030] Based on this, we propose a high reliability starting device for a fire extinguishing device, comprising a device body 1, a connecting component 2 and a temperature sensing cable 4;

[0031] A plurality of through holes are provided on the same side of the device body 1, and a connecting component 2 is provided in the through hole. An electrode is provided inside the connecting component for connecting a temperature sensing cable 4;

[0032] The device body 1 is provided with an energy storage component, generally a battery,

[0033] One end of the temperature sensing cable 4 is connected to the electrode, and the other end is connected to the energy storage component inside the device body 1 .

[0034] The connection assembly 2 includes N plug-in posts 21 . An inserting port 22 is provided at one end of the plug-in post 21 and completely penetrates the plug-in post 21 . A threaded port 23 is provided on the outer side of the plug-in post 21 .

[0035] In the embodiment, the number of the plug posts 21 is set to 2, so that the temperature sensing cable 4 and the electrical device 3 can be conveniently connected. The structure of the connection component 2 is similar to the connection method of a screw-type light bulb. The metal contacts are in contact through the thread, and the battery is used to achieve the effect of power supply.

[0036] The electrical equipment 3 is generally a fire extinguishing device or an alarm, and the signal transmission is realized by electrical connection;

[0037] The device body 1 includes a shell 11, a base 14 is provided on one side of the shell 11, a connection port 12 is provided at the base 14, a threaded connection area 13 is provided at the connection port 12, and the threaded connection area 13 is adapted to a threaded thread port 23 provided on the outer side of the plug-in column 21.

[0038] One side of the plug-in post 21 is a flange, which is integrally formed and has a diameter greater than the diameter of the plug-in post 21. Such a design makes the plug-in post 21 easier to hold and operate, and provides a convenient installation and disassembly method.

[0039] Both ends of the plug-in column 21 are completely penetrated to form plug-in interfaces 22, which are adapted to the temperature sensing cable 4 and the electrical equipment 3 and are used to connect to the device body 1. The temperature sensing cable 4 and the electrical equipment 3 can be connected to the plug-in column 21 through the plug-in interfaces 22 to achieve circuit connectivity.

[0040] A temperature control switch 7 is provided on the temperature sensing cable 4 . The temperature control switch 7 is connected in parallel with the temperature sensing cable 4 . A thermistor wire 5 is wound around the outer side of the temperature control switch 7 through a connector 6 .

[0041] Embodiment 1:

[0042] See also Figure 4 In this embodiment, a temperature control switch 7 is installed at one end of the temperature sensing cable 4 located at the threaded thread 23, and a thermistor 5 is wound around the outside of the temperature control switch 7. At this time, the thermistor 5 is combined by a connector 6. At this time, the thermistor 5 and the temperature sensing cable 4 are detected. Since the thermistor 5 will burn after reaching a predetermined temperature, and the temperature sensing cable 4 will close without generating sparks after reaching a predetermined temperature, the two can be placed in different environments for detection. The thermistor 5 itself cannot generate a closing signal to close the system and generate current, so it needs to be used in conjunction with the temperature control switch 7. The temperature control switch 7 and the temperature sensing cable 4 are connected in parallel, and any signal can power on the system.

[0043] Of course, the thermistor wire 5 and the temperature sensing cable 4 can be placed in a protection area to prevent one of the detection methods from failing.

[0044] A thermistor 5 is provided on the temperature sensing cable 4 . The thermistor 5 is tightly attached to the outer side of the temperature sensing cable 4 . Both ends of the thermistor 5 are wound around a connector 6 to fix the thermistor 5 .

[0045] Embodiment 2:

[0046] See also Figure 2 : In this embodiment, one end of the temperature sensing cable 4 is connected to the threaded thread 23 and combined with the base 14;

[0047] The other end of the temperature sensing cable 4 is provided with a connector 6, and there are at least two connectors 6, which are far away from each other. A thermal wire 5 is wound between the two connectors 6, and the thermal wire 5 is tightly attached to the outer side of the temperature sensing cable 4;

[0048] At this time, in order to fix the thermal wire 5, the connecting pieces 6 at both ends thereof include ring bodies 62, and the ends of the two ring bodies 62 close to each other are both provided with winding protrusions 63, and the outer side of the winding protrusions 63 is provided with winding grooves 61, and the outer side of the thermal wire 5 is wound and connected with the winding grooves 61, so as to fix the thermal wire 5;

[0049] The winding spacing of the thermistor wire 5 can be adjusted by the distance between the two connectors 6 , and when the ring body 62 is combined with the temperature sensing cable 4 , its inner side is clamped and fixed to the temperature sensing cable 4 by elastic members, and can adapt to different diameters of the temperature sensing cable 4 .

[0050] The connecting member 6 includes at least two ring bodies 62 . N winding protrusions 63 are provided on the sides of the two ring bodies 62 close to each other. A winding groove 61 is provided on the outer side of the winding protrusion 63 . The winding groove 61 is adapted to the thermal line 5 .

[0051] Assuming that the number of winding protrusions 63 is 2, both ends of the thermal wire 5 are wound around the winding groove 61, thereby fixing both ends of the thermal wire 5 to meet the need of fixing the thermal wire;

[0052] One of the plug posts 21 is connected to an electric device 3 via a cable, and the other end of the cable is connected to an energy storage component provided inside the device body 1 .

[0053] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
