Description

Technical Field

[0001] The utility model relates to the technical field of combustible gas monitoring, in particular to a combustible gas monitoring and alarm device. Background Art

[0002] Combustible gas monitoring and alarm devices are used to detect and warn of combustible gas leaks. They play a crucial role in industrial production and household safety, providing timely warnings of potential explosion and poisoning risks. These devices typically consist of sensors, controllers, and alarm systems. Through sophisticated sensors and control systems, they monitor combustible gas concentrations in real time and issue prompt alarms when levels exceed permitted limits, effectively preventing industrial accidents and household hazards.

[0003] A combustible gas monitoring and alarm device disclosed in publication number CN220672056U, although the utility model is provided with a pushing assembly, by placing the gas monitoring box on the mounting seat and inserting the air inlet pipe into the interior of the gas monitoring box along the air inlet, the fixed plate, threaded rod, handle and limit rod are used in conjunction to drive the splint to move, so that the two splints can clamp the gas monitoring box on the mounting seat, thereby realizing the installation operation of the gas monitoring box. There is no need to install the gas monitoring box by bolt fixing, so that when the gas monitoring box needs to be disassembled for inspection later, the operation is more convenient.

[0004] However, combustible gas monitoring is a long process that requires continuous power support during use. However, the device is difficult to operate stably for a long time in an environment where the power cannot be connected. In addition, the position of the left and right sides of the device need to be adjusted and locked during installation, and manual operation is relatively cumbersome. Utility Model Content

[0030] Example 1

[0031] Reference Figure 1-5 , which is the first embodiment of the present utility model, provides a combustible gas monitoring and alarm device, which includes:

[0032] An exhaust duct 100 is fixedly connected to one side of the exhaust duct 100 with an installation box 101. A gas monitoring box 102 is provided on the installation box 101. The gas monitoring box 102 is placed on the installation box 101. The combustible gas in the exhaust duct 100 enters the gas monitoring box 102 through the air inlet pipe 103. The concentration of the combustible gas is detected by the gas monitoring box 102.

[0033] The power generation assembly 200 includes a control cabinet 201. A generator 202 is fixedly mounted on one side of the control cabinet 201. A rotor 203 is provided on one side of the generator 202. A gearbox 204 is also provided on one side of the generator 202. During use, combustible gas enters the exhaust duct 100, and the blades 2032 capture wind energy and begin to rotate. The rotation of the blades 2032 and the hub 2031 is transmitted to the generator 202 through the gearbox 204, thereby converting mechanical energy into electrical energy. The stirring of the blades 2032 ensures that the gas entering the intake pipe 103 is evenly mixed.

[0034] The fixing assembly 300 includes a servo motor 301. The output end of the servo motor 301 is driven and connected to the first bevel gear 302. The surface of the first bevel gear 302 is meshed with the second bevel gear 303. The center rotation of the second bevel gear 303 is connected to the bidirectional screw 304. The surface of the bidirectional screw 304 is threadedly connected to the movable block 305. During use, the servo motor 301 is started to drive the first bevel gear 302 to rotate, and then drive the second bevel gear 303 to rotate, so that the bidirectional screw 304 rotates. At this time, the two movable blocks 305 move toward each other on the surface of the bidirectional screw 304, driving the two clamps 3051 to clamp and fix the gas monitoring box 102.

[0035] Furthermore, an air intake pipe 103 is provided on one side of the exhaust pipe 100, a filter 1031 is provided on the inner wall of the air intake pipe 103, and a sealing ring 1032 is provided at one end of the air intake pipe 103. The combustible gas enters the gas monitoring box 102 through the air intake pipe 103 on the exhaust pipe 100, and the smoke and dust are filtered by the filter 1031 to prevent dust accumulation in the gas monitoring box 102 and blockage. By replacing the sealing ring 1032, the air intake pipe 103 can adapt to air inlets of different sizes, thereby increasing the sealing of the gas monitoring box 102.

[0036] Furthermore, a first cavity and a second cavity are opened inside the installation box 101, the second bevel gear 303 is arranged in the first cavity, and the power generation component 200 is fixedly installed in the second cavity. The fixing component 300 and the power generation component 200 are installed and fixed through the first cavity and the second cavity.

[0037] Furthermore, a display screen 1021 is provided on the front of the gas monitoring box 102, and an alarm 1022 is also provided on the front of the gas monitoring box 102. The gas monitoring data can be clearly displayed through the display screen 1021, and an alarm is sounded through the alarm 1022 when the concentration exceeds the standard.

[0038] Furthermore, one end of the rotor 203 is fixedly connected to a hub 2031 , and blades 2032 are provided on the surface of the hub 2031 . The hub 2031 drives the blades 2032 to rotate, converting the wind force generated by the gas circulation into mechanical energy to help the generator 202 generate electricity.

[0039] Furthermore, a splint 3051 is fixedly connected to the top of the movable block 305, and an anti-slip pad 3052 is fixedly installed on the opposite side of the splint 3051. The gas monitoring box 102 is clamped and fixed by the two splints 3051. The anti-slip pad 3052 can increase the friction between the splint 3051 and the gas monitoring box 102, thereby increasing the stability of the installation.

[0040] During use, the gas monitoring box 102 is first placed on the installation box 101, and the servo motor 301 is started to drive the first bevel gear 302 to rotate, thereby driving the second bevel gear 303 to rotate, and the bidirectional screw 304 to rotate. At this time, the two movable blocks 305 move toward each other on the surface of the bidirectional screw 304, driving the two clamping plates 3051 to clamp and fix the gas monitoring box 102. The anti-slip pad 3052 can increase the friction between the clamping plates 3051 and the gas monitoring box 102, thereby increasing the stability of the installation;

[0041] The combustible gas then enters the exhaust duct 100, and the blades 2032 capture wind energy and begin to rotate. The rotation of the blades 2032 and the hub 2031 is transmitted to the generator 202 through the gearbox 204, thereby converting mechanical energy into electrical energy, which in turn provides power support for the gas monitoring box 102 and the servo motor 301, thereby maintaining long-term stable operation of the gas monitoring box 102 in an environment where power cannot be connected;

[0042] Finally, due to the stirring of the blades 2032, the gas entering the intake pipe 103 is mixed evenly, and the combustible gas in the exhaust pipe 100 enters the gas monitoring box 102 through the intake pipe 103. The smoke and dust are filtered by the filter 1031 to prevent dust accumulation in the gas monitoring box 102 from causing blockage. By replacing the sealing ring 1032, the intake pipe 103 can adapt to air inlets of different sizes, increase the sealing performance of the gas monitoring box 102, and detect the concentration of the combustible gas through the gas monitoring box 102.

[0043] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
