Description

Technical Field

[0001] This utility model belongs to the field of natural gas leak monitoring technology, specifically relating to a fire early warning linkage device based on natural gas leak monitoring. Background Technology

[0002] The fire alarm and linkage device based on natural gas leak monitoring is a safety system that integrates monitoring, early warning, and linkage control. It uses a high-sensitivity sensor to detect the natural gas concentration in real time. When the concentration exceeds a safe threshold, it immediately triggers an audible and visual alarm and automatically shuts off gas valves, activates ventilation equipment, or activates the fire suppression system. The device employs mechanical or electronic control methods to ensure rapid response and effectively prevent fires or explosions. It is widely used in homes, industrial facilities, and commercial spaces to protect life and property.

[0003] Traditional linkage systems may experience delays in their control actions, such as closing valves or activating ventilation, after a gas leak is detected by a sensor. This delay can increase the risk. These delays are typically caused by the time consumed in signal transmission, control unit response, and actuator action. After a leak is detected, the signal needs to be processed and transmitted to the control unit. The control unit then makes a judgment and issues an execution command, and finally, the actuator, such as a valve or ventilation equipment, can complete the action. Any lag in any step of this process can increase the amount of gas leaked, thereby increasing the risk of fire or explosion. Utility Model Content

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example

[0026] Reference Figure 1-4 This embodiment of the present invention provides a fire alarm linkage device based on natural gas leak monitoring, comprising:

[0027] The pipeline structure 100 includes a gas pipeline 101 and a push-button control valve 102 adapted to be installed on the gas pipeline 101.

[0028] The control mechanism 200 includes a shut-off component 201 for automatically closing the push-button control valve 102 and a ventilation component 202 for ventilation.

[0029] In particular, by cooperating between the shut-off component 201 and the ventilation component 202, the gas valve can be quickly shut off and ventilation can be started in the event of a gas leak using a purely mechanical method. This solves the delay problem that may be caused by signal transmission and control unit response in traditional linkage devices, improves the response speed, and at the same time, the purely mechanical structure reduces the reliance on electronic components, enhances the reliability of the device, and effectively reduces the safety risks after a gas leak.

[0030] Specifically, the closing component 201 includes a support frame 201a fixedly mounted on the surface of the push-button control valve 102, a compression spring 201b fixedly mounted on the surface of the support frame 201a, and a push plate 201c fixedly mounted on the end of the compression spring 201b for pressing the push-button control valve 102.

[0031] Furthermore, the closing component 201 also includes two locking plates 201d disposed on the surface of the support frame 201a for engaging with the push plate 201c, and a connecting spring 201e fixedly installed between the two locking plates 201d.

[0032] Preferably, two positioning rods are fixedly installed on the surface of the support frame 201a, and positioning holes for use with the positioning rods are opened on the surface of the clamping plate 201d.

[0033] The positioning rod and the positioning hole are used to limit the movement of the two clamping plates 201d, thereby improving the stability of the movement of the clamping plates 201d.

[0034] Furthermore, the ventilation component 202 includes a mounting bracket 202a fixedly mounted on the surface of the support frame 201a, a motor 202b fixedly mounted on the mounting bracket 202a, a ventilation fan blade 202c fixedly mounted on the output end of the motor 202b, and an exhaust duct 202d fixedly mounted on the surface of the mounting bracket 202a.

[0035] Among them, the ventilation fan blade 202c is located inside the exhaust duct 202d, which is connected to the ventilation pipe. It is used to discharge gas through the ventilation pipe in case of gas leakage. The motor 202b is used to drive the transmission cam 202e to rotate. The transmission cam 202e quickly discharges indoor air through the ventilation fan blade 202c and the ventilation pipe to prevent gas explosion.

[0036] It should be noted that the gas leak detection sensor directly controls the start and stop of motor 202b through a simple circuit (such as a relay or transistor switch).

[0037] Specifically, the ventilation component 202 also includes a transmission cam 202e fixedly installed at the output end of the motor 202b, and a transmission block 202f slidably disposed inside the mounting bracket 202a and used in conjunction with the transmission cam 202e.

[0038] The transmission block 202f has a slot on its surface that engages with the end face of the clamping plate 201d. Under the action of the motor 202b, the transmission cam 202e is driven to rotate. When the transmission cam 202e rotates, it moves the transmission block 202f downward, causing the inclined surface of the transmission block 202f to press against the two clamping plates 201d. This causes the clamping plates 201d to move and disengage from the push plate 201c, thereby triggering the compression spring 201b to spring the push plate 201c downward and close the push-type control valve 102, reducing the electronic control links and improving the response speed.

[0039] Furthermore, two limiting rods 202g are fixedly installed on the surface of the transmission block 202f, and baffles are fixedly installed on the surface of the limiting rods 202g.

[0040] The mounting bracket 202a has a groove on its surface that is used to cooperate with the limiting rod 202g. The end of the limiting rod 202g is engaged in the inside of the groove, and the baffle on the limiting rod 202g is used to limit the transmission block 202f.

[0041] When in use, when the sensor detects a gas leak, it will control the motor 202b to start. Under the action of the motor 202b, the transmission cam 202e will rotate. The transmission cam 202e will quickly discharge the indoor air through the ventilation fan blades 202c and the ventilation pipe, thereby discharging the leaked gas and reducing the indoor gas concentration.

[0042] When the motor 202b drives the transmission cam 202e to rotate, the exhaust pipe 202d drives the transmission cam 202e to rotate. When the transmission cam 202e rotates, it will squeeze the transmission block 202f and make it move downward. The inclined surface of the transmission block 202f squeezes the two clamping plates 201d, causing the clamping plates 201d to move and disengage from the push plate 201c, thereby triggering the compression spring 201b to push the push plate 201c downward. The push plate 201c presses the push-type control valve 102 to close it and prevent the gas from continuing to pass through the gas pipeline 101. The end of the clamping plate 201d will be engaged in the groove on the surface of the transmission block 202f, and the connecting spring 201e is in a stretched state.

[0043] In summary, by coordinating the shut-off component 201 and the ventilation component 202, the gas valve can be quickly shut off and ventilation can be started in the event of a gas leak using a purely mechanical method. This solves the delay problem that may be caused by signal transmission and control unit response in traditional linkage devices, improves the response speed, and at the same time, the purely mechanical structure reduces the reliance on electronic components, enhances the reliability of the device, and effectively reduces the safety risks after a gas leak.
