Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, and more specifically to a mechanically activated self-generating temperature detector device. Background Technology

[0002] Among existing automatic fire extinguishing devices, non-pressurized fire extinguishing devices have gained widespread market recognition due to their excellent fire extinguishing performance, stability and safety during use, and ease of installation and maintenance.

[0003] Non-pressurized fire extinguishing devices are mainly activated by two methods: thermal wire ignition and electric ignition. Electric ignition requires continuous power supply and is at risk of failure in the event of circuit failure or power outage. Thermal wire ignition uses a heat-sensitive ignition wire for activation, which is accompanied by intense combustion and exposed sparks during activation, making it unsuitable for flammable and explosive environments. Utility Model Content

[0004] To address the aforementioned shortcomings in the existing technology, this utility model provides a mechanically activated self-generating temperature detector that requires no external power source, operates without open flame during startup, and generates its own electricity at a preset temperature. It is suitable for fire detection and extinguishing in specific environments.

[0005] The purpose of this utility model is achieved as follows:

[0006] A mechanically activated self-generating temperature sensor device, comprising:

[0007] The upper housing has a through hole at the top;

[0008] A fusible alloy nut is disposed at the top of the upper housing;

[0009] The firing pin is slidably disposed in the inner cavity of the upper housing, with its top end protruding through the top through hole of the upper housing and having an external thread structure at the top end;

[0010] A spring is sleeved on the upper part of the firing pin and located in the inner cavity of the upper housing;

[0011] The lower housing is connected to the upper housing via a threaded structure.

[0012] The primer ignition element is fixedly mounted on the top of the lower housing;

[0013] Electrolyte, contained within the cavity of the lower housing;

[0014] The current output terminal is located at the bottom of the lower housing;

[0015] The positive and negative terminals are connected to the bottom of the current output terminal.

[0016] Furthermore, the external thread structure at the tip of the firing pin is connected to the fusible alloy nut via a thread, so that the firing pin is constrained to the initial position at room temperature.

[0017] Furthermore, the bottom end of the firing pin is axially aligned with the trigger surface of the primer firing element, maintaining a preset distance.

[0018] Furthermore, the lower surface of the primer firing element is connected to the top of the electrolyte.

[0019] Furthermore, the bottom of the electrolyte is connected to the top of the current output terminal, and the current generated by the electrolyte is transmitted through the current output terminal, the positive terminal, and the negative terminal.

[0020] The detection signal current generated by the mechanically activated self-generating temperature detector is transmitted to an external linkage system (such as an alarm controller or fire extinguishing device starter) via a wire. Upon receiving the current signal, the external linkage system triggers and executes a predetermined action (such as issuing an alarm or initiating a fire extinguishing procedure), thereby achieving a rapid system response.

[0021] Compared with the prior art, the mechanically activated self-generating temperature detector provided by this utility model has the characteristics of corrosion resistance, moisture resistance, long life, high accuracy and low false alarm rate. It does not require an external power supply, detects temperature and emits current signal on its own, and occupies little space. It is especially suitable for fire detection in small complex spaces, special places without electricity and explosion-proof places. Attached Figure Description

[0032] A specific embodiment of this utility model discloses a mechanically activated self-generating heat detector device, which is particularly suitable for early fire detection and linkage fire extinguishing systems in places without power supply or explosion protection.

[0033] like Figures 1 to 2 As shown, the mechanically activated self-generating temperature detector device of this utility model includes the following components: an upper housing 2, a fusible alloy nut 1, a striking pin 4, a spring 3, a lower housing 6, a primer ignition element 5, an electrolyte 7, a current output terminal 8, a positive terminal 9, and a negative terminal 10. The upper housing 2 has a through hole at its top; the fusible alloy nut 1 is disposed at the top of the upper housing 2; the striking pin 4 is slidably disposed in the inner cavity of the upper housing 2, with its top end protruding from the through hole at the top of the upper housing 2 and having an external thread structure at its top end; the spring 3 is sleeved on the upper part of the striking pin 4 and located in the inner cavity of the upper housing 2; the lower housing 6 is connected to the upper housing 2 via a threaded connection; the primer ignition element 5 is fixedly disposed at the top of the lower housing 6; the electrolyte 7 is housed in the inner cavity of the lower housing 6; the current output terminal 8 is disposed at the bottom of the lower housing 6; the positive terminal 9 and the negative terminal 10 are respectively connected to the bottom of the current output terminal 8.

[0034] In this embodiment, the external thread structure at the tip of the firing pin 4 is connected to the fusible alloy nut 1 by a thread, so that the firing pin 4 is constrained to the initial position at room temperature.

[0035] In this embodiment, the bottom end of the firing pin 4 is axially aligned with the trigger surface of the primer firing element 5 and maintains a preset distance, which is set according to the trigger sensitivity requirements of the device.

[0036] In this embodiment, the lower surface of the primer excitation element 5 is connected to the top of the electrolyte 7 to ensure that the excitation signal can be effectively transmitted to the electrolyte.

[0037] In this embodiment, the bottom of the electrolyte 7 is connected to the top of the current output terminal 8, thereby achieving an effective connection between the ion conduction path and the current output.

[0038] The working principle is as follows: When the ambient temperature rises to the melting point threshold of the fusible alloy nut 1, the fusible alloy nut 1 undergoes a melting phase change, releasing the constraint on the striker 4. The spring 3, in a compressed energy storage state, drives the striker 4 downwards along its axis using its elastic restoring force, striking the primer ignition element 5. Upon impact, the primer ignition element 5 triggers a chemical reaction and releases heat energy, heating and activating the electrolyte 7 below, causing it to melt. After activation, the ions in the electrolyte 7 migrate with temperature changes, leading to an internal charge imbalance and generating current. This current is transmitted through the current output terminal 8, via the positive terminal 9 and the negative terminal 10.

[0039] Compared to the "Self-generating Temperature Detector" in authorization announcement number CN222211988U, which relies on a temperature-sensing ignition wire for activation, this ignition wire is essentially a fuse, resulting in violent combustion and exposed sparks upon activation, making it unsuitable for flammable and explosive environments. The mechanically activated temperature detector device provided by this utility model has significant advantages: First, it employs a fusible alloy temperature-sensing trigger mechanism, utilizing the physical melting characteristics of the fusible alloy nut to accurately sense the temperature threshold. Second, it uses a purely mechanical activation method, where a spring releases mechanical energy to drive a striker to strike the primer ignition element; the activation process involves no combustion or open flame. Third, it features a fully sealed protective shell structure; the entire process of temperature sensing, mechanical drive, primer ignition, and power generation is completed within a closed cavity formed by the upper and lower shells, with no exposed sparks or flames, making it inherently safe and particularly suitable for flammable and explosive hazardous environments.

[0040] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this application. It should be understood that the above description is only a specific embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
