Description

Technical Field

[0001] This utility model relates to the technical field of gas alarm devices, and in particular to a gas alarm device that can simulate high and low alarm functions. Background Technology

[0002] A combustible gas detection and alarm system consists of a combustible gas detector, a combustible gas alarm controller, and a fire audible and visual alarm. It can provide early warning when the concentration of leaked combustible gas in the protected area is below the lower explosive limit, thereby preventing fires and explosions caused by combustible gas leaks. This system is suitable for places where combustible gases or combustible liquid vapors are used, produced, or stored, enabling early fire prevention and avoiding fire and explosion accidents.

[0003] Since it takes time for gas to travel from the leak point to the sensor location, this causes a delay in the system's response time to leak events. In emergency situations, this delay may increase safety risks. Therefore, there is a need to provide a method that can increase the airflow velocity within the detection area, thereby improving detection speed and sensitivity. Utility Model Content

[0004] The purpose of this invention is to provide a gas alarm device that can simulate high and low alarm functions, in order to solve the problem mentioned in the background art, that since gas needs time to travel from the leak point to the location of the sensor, this will cause a delay in the system's response time to the leak event, and in emergency situations, this delay may increase safety risks.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a gas alarm device that can simulate high and low alarm functions, comprising:

[0007] The detector body and the sensor are fixed to the lower side of the detector body.

[0008] The sensing component includes a fixed block, a motor, a fan, and two side frames. The fixed block is located directly below the sensor, the motor is fixedly installed inside the center of the fixed block, the fan is fixed at the output end of the motor, and the two side frames are fixed at both ends of the fixed block.

[0009] Furthermore, the fan draws in air from below and blows it out from above.

[0010] Furthermore, a fixing plate is slidably installed inside the side frame, and a threaded rod is threaded through one end of the fixing plate, with a rotating ring rotatably installed on one side of the threaded rod.

[0011] Furthermore, a clamping block is fixed to one side of the rotating ring, and one side of the clamping block is in contact with the outer surface of the sensor.

[0012] Furthermore, it also includes an adjustment component, which includes mounting holes, springs, and locking pins. The mounting holes are opened on both sides of one end of the fixed plate, two springs are fixed inside the corresponding mounting holes, and a locking pin is fixed to one end of each spring.

[0013] Furthermore, the side frame has fixing holes on both sides, and the end of the locking post extends into the fixing hole.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. In this utility model, the detector body, sensor and sensing component are set up so that when in use, the threaded rod is rotated and rotated inside the rotating ring. The threaded rod moves inside the fixed plate and drives the clamping block to move synchronously. The clamping block is fixed on the outer surface of the sensor. Then, the motor is started and the motor drives the fan to rotate, so that the air flows from the direction of the motor to the direction of the fan (23). By increasing the air flow speed in the detection area, the gas can spread to the location of the sensor more quickly, thereby improving the detection speed of the gas alarm device.

[0016] Second, based on the first beneficial effect, by setting the adjustment component, during installation, the operator only needs to press the locking pin to compress the spring inside the mounting hole and make the locking pin retract from the fixing hole. Then, adjust the position of the fixing plate so that the locking pin is inserted into the appropriate fixing hole. Adjust the length of the installed sensing component. The position of the fixing plate can be adjusted according to actual needs, so that the sensing component can adapt to different installation environments and space constraints, thus improving the applicability of the device.

[0028] 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.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] Please see Figures 1 to 5 As shown, this embodiment is a gas alarm device that can simulate high and low alarm functions, including:

[0032] The detector body 11 and the sensor 12 are fixed to the lower side of the detector body 11.

[0033] The detector body 11 is the main structure of the entire gas alarm device, used to install and support other components. It is usually made of robust materials to ensure the stability and durability of the device. The sensor 12 is responsible for detecting the concentration of a specific gas in the environment.

[0034] The sensing component includes a fixing block 21, a motor 22, a fan 23 and side mounting frames 24. The fixing block 21 is located directly below the sensor 12. The motor 22 is fixedly installed inside the center of the fixing block 21. The fan 23 is fixed at the output end of the motor 22, and the two side mounting frames 24 are fixed at both ends of the fixing block 21.

[0035] The fixing block 21 is used to install and fix the motor 22, providing a stable platform to ensure the correct positioning and operation of the motor 22 and the fan 23. When the motor 22 starts, it will drive the fan 23 to rotate, thereby generating airflow, increasing the airflow speed, and helping the gas to reach the sensor 12 faster. The side frame 24 provides space for the fixing plate 25 to slide.

[0036] The fan 23 draws air from below and blows it out from above. A fixing plate 25 is slidably installed inside the side frame 24. A threaded rod 26 is threaded through one end of the fixing plate 25. A rotating ring 27 is rotatably installed on one side of the threaded rod 26. A clamping block 28 is fixed on one side of the rotating ring 27, and one side of the clamping block 28 is in contact with the outer surface of the sensor 12.

[0037] Rotating the threaded rod 26 can drive the clamping block 28 to move, which is convenient for operation and maintenance. The rotating ring 27 is used to convert the rotational motion of the threaded rod 26 into the linear motion of the clamping block 28, which helps to accurately control the position of the clamping block. The clamping block 28 is used to fix the sensor 12 in the appropriate position.

[0038] Working principle:

[0039] When in use, rotate the threaded rod 26. The threaded rod 26 rotates inside the rotating ring 27 and moves inside the fixed plate 25. The threaded rod 26 synchronously drives the clamping block 28 to move and fixes the clamping block 28 on the outer surface of the sensor 12. Then, start the motor 22. The motor 22 drives the fan 23 to rotate, so that the air flows from the direction of the motor 22 to the direction of the fan (23).

[0040] This step increases the airflow speed within the detection area, allowing the gas to travel to the location of sensor 12 more quickly, thereby improving the detection speed of the gas alarm device.

[0041] Please see Figures 1 to 5 As shown; this embodiment, based on the above embodiment, further includes:

[0042] The adjustment assembly includes mounting holes 32, springs 33, and locking posts 34. The mounting holes 32 are opened on both sides of one end of the fixing plate 25. Two springs 33 are fixed inside the corresponding mounting holes 32. One end of the spring 33 is fixed with a locking post 34. Fixing holes 31 are opened on both sides of the side frame 24, and the end of the locking post 34 extends into the fixing hole 31.

[0043] Mounting hole 32 allows spring 33 and locking pin 34 to be mounted and fixed on fixing plate 25, while also providing space for spring 33 to compress and rebound.

[0044] Working principle:

[0045] During installation, the operator only needs to press the locking pin 34 to compress the spring 33 inside the mounting hole 32 and remove the locking pin 34 from the fixing hole 31. Then, adjust the position of the fixing plate 25 so that the locking pin 34 is inserted into the appropriate fixing hole 31 and adjust the length of the sensor component.

[0046] This step allows the position of the fixing plate 25 to be adjusted according to actual needs, enabling the sensing components to adapt to different installation environments and space constraints, thus improving the applicability of the device.

[0048] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
