Description

Technical Field

[0001] This invention relates to the field of gas detection, and more particularly to an environmentally adaptive gas leak detection alarm. Background Technology

[0002] In petrochemical, chemical industrial parks, gas transmission, warehousing and logistics, and household settings, the risk of leakage of toxic, harmful, flammable and explosive gases always exists. Once a gas leak occurs, it may not only cause safety accidents such as explosions and fires, but also lead to poisoning and suffocation, posing a serious threat to life, property safety and the ecological environment.

[0003] Existing gas leak detection alarms are typically fixed in a specific location using bolts, brackets, or other structures. Once installed, their shape and position are difficult to adjust. If the detection area needs to be changed, the original installation structure must be disassembled and re-drilled and fixed, which is cumbersome and time-consuming. This not only affects installation efficiency but may also damage the installation surface. It is also difficult to quickly adjust to different installation scenarios, resulting in poor flexibility and seriously affecting detection efficiency.

[0004] Therefore, it is necessary to design a gas leak detection alarm that can be quickly adjusted in shape and installed in different positions to detect gas while providing early warning, so as to facilitate quick relocation to adapt to different environments and scenarios, improve detection efficiency, and provide a flexible environment-adaptive gas leak detection alarm. Summary of the Invention

[0005] To overcome the shortcomings of existing gas leak detection alarms, such as cumbersome and time-consuming operation, which not only affects installation efficiency but may also damage the mounting surface, difficulty in quickly adjusting to adapt to different installation scenarios, poor flexibility, and serious impact on detection efficiency, this invention provides a gas leak detection alarm that can be quickly adjusted in shape and installed in different positions to provide early warning while detecting gas. It is easy to quickly change positions to adapt to different environments and scenarios, improves detection efficiency, and is a flexible, environment-adaptive gas leak detection alarm.

[0006] The technical solution is as follows: An environmentally adaptive gas leak detection alarm includes a fixed plate, telescopic rods, lead screws, a rotating plate, a detection chamber, a fan, a catalytic combustion sensor, an electrochemical sensor, support blocks, an alarm, clamping components, and limiting components. The fixed plate has two parts, upper and lower. The lower fixed plate has two telescopic rods connected to its rear lower side, with the telescopic ends of the rods connected to the lower fixed plate. The lower fixed plate has a lead screw rotatably connected to its rear, which is threaded to the upper fixed plate. The upper fixed plate has a rotating plate rotatably connected to its upper part, with a detection chamber connected to its upper side. A fan is connected to the right side of the detection chamber. A catalytic combustion sensor is connected to the bottom of the detection chamber, and an electrochemical sensor is connected to the lower inner side of the detection chamber. Support blocks are connected to both sides of the lower fixed plate, and an alarm is connected to the upper right side of the detection chamber. Both the catalytic combustion sensor and the electrochemical sensor are electrically connected to the alarm. The fixed plate has clamping components for clamping and installing the device, and the upper left side of the upper fixed plate has a limiting component for limiting the rotation plate.

[0007] More preferably, the support blocks are all U-shaped.

[0008] More preferably, it also includes a handle, with a handle connected to the upper side of the lead screw.

[0009] More preferably, the clamping assembly includes a slider, a clamping block, a fixing screw, and a fixing knob. The slider is slidably connected to the side of the fixing plates that are close to each other. The clamping block is detachably connected to the slider by two fixing screws on the left and right sides. The fixing knob is threadedly connected to the side of the fixing plates that are far from each other. The fixing knob passes through the slider on the same side.

[0010] More preferably, the fixing screws are all provided with cross-shaped grooves.

[0011] More preferably, all clamping blocks are triangular.

[0012] Even more preferably, the fixed knobs are all equipped with anti-slip textures.

[0013] More preferably, the limiting assembly includes a limiting plate, a limiting block, and springs. The upper left side of the upper fixed plate is connected to the limiting plate, the limiting block is slidably connected to the limiting plate, the limiting block is engaged with the rotating plate, and two springs are connected between the limiting block and the limiting plate.

[0014] More preferably, the right side of the limiting block is C-shaped.

[0015] More preferably, it also includes a filter screen, which is connected to the right side of the fan.

[0016] Beneficial effects: 1. This invention places the support block on a table or clamps the device onto a cabinet or pipe using a combination of clamping blocks, sliders, lead screws, and telescopic rods. Air then flows into the detection chamber, where the gas is detected by an electrochemical sensor or a catalytic combustion sensor, and an alarm sounds to alert the user. This allows for quick adjustment of the device's position to detect gas while providing early warnings, facilitating rapid relocation to adapt to different environments and scenarios, improving detection efficiency, and offering flexible use.

[0017] 2. According to the detection position, the detection chamber can be rotated by hand to make the rotating plate rotate, which in turn drives the fan to rotate to the other side. After adjusting the angle, the limiting block moves and resets to lock with the rotating plate for fixation. Then, the above operation is repeated to detect and warn of gas. This allows the angle of the fan to be adjusted according to the detection area to draw in air for detection, thereby expanding the detection coverage and improving detection accuracy.

Detailed Implementation

[0029] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0030] An environmentally adaptive gas leak detection alarm, such as Figures 1-10 As shown, the system includes a fixed plate 1, telescopic rods 2, lead screws 3, handles 4, rotating plates 9, a detection chamber 10, a fan 11, a filter 12, a catalytic combustion sensor 13, an electrochemical sensor 14, a support block 18, an alarm 19, a clamping assembly, and a limiting assembly. The fixed plate 1 has two parts, upper and lower. The lower part of the upper fixed plate 1 is connected to two telescopic rods 2, both on the left and right sides. The telescopic ends of the telescopic rods 2 are connected to the lower fixed plate 1. The lower fixed plate 1 is rotatably connected to a lead screw 3, which is threaded to the upper fixed plate 1. A handle 4 is connected to the upper side of the lead screw 3 for easy gripping and rotation. The upper part of the upper fixed plate 1 is rotatably connected to a rotating plate 9. The upper side of the rotating plate 9... The device is connected to a detection chamber 10. A fan 11 is connected to the right side of the detection chamber 10. A filter 12 is connected to the right side of the fan 11 to facilitate the filtration of impurities. A catalytic combustion sensor 13 is connected to the bottom of the detection chamber 10. An electrochemical sensor 14 is connected to the inner side of the lower part of the detection chamber 10. Support blocks 18 are connected to both the left and right sides of the lower fixing plate 1. The support blocks 18 are U-shaped to facilitate support. An alarm 19 is connected to the upper right side of the detection chamber 10. The catalytic combustion sensor 13 and the electrochemical sensor 14 are electrically connected to the alarm 19. The fixing plate 1 is equipped with clamping components for clamping and installing the device. The upper left side of the upper fixing plate 1 is equipped with a limiting component for limiting the rotation plate 9.

[0031] like Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, the clamping assembly includes a slider 5, a clamping block 6, a fixing screw 7, and a fixing knob 8. The slider 5 is slidably connected to the side of the fixing plate 1 that is close to each other. The clamping block 6 is detachably connected to the slider 5 by two fixing screws 7 on the left and right sides. The clamping block 6 is triangular to fit the shape of the slider 5. The fixing screw 7 is provided with a cross groove to facilitate the insertion and tightening of tools for installation. The fixing knob 8 is threadedly connected to the side of the fixing plate 1 that is far from each other. The fixing knob 8 passes through the slider 5 on the same side. The fixing knob 8 is provided with anti-slip texture to prevent slipping.

[0032] like Figure 3 and Figure 4 As shown, the limiting assembly includes a limiting plate 15, a limiting block 16, and a spring 17. The upper left side of the upper fixing plate 1 is connected to the limiting plate 15, and the limiting block 16 is slidably connected to the limiting plate 15. The limiting block 16 is engaged with the rotating plate 9. The right side of the limiting block 16 is C-shaped to facilitate fixing the rotating plate 9. Two springs 17 are connected between the limiting block 16 and the limiting plate 15.

[0033] This device can be used when gas leak detection and alarm are required in different scenarios. Depending on the scenario, when used indoors, the support block 18 is placed directly on the table. All support blocks 18 are U-shaped. Alternatively, the clamping block 6 can be placed in contact with the slider 5. Then, a tool is used to insert into the cross-shaped groove and rotate the fixing screw 7 to fix the clamping block 6 in place. After installation, the device is lifted and turned over so that the lower clamping block 6 contacts the edge of the cabinet. All clamping blocks 6 are triangular. Then, by rotating the screw 3 through the handle 4, the upper fixing plate 1 moves under the action of the thread, which in turn causes the telescopic rod 2 to retract, driving the upper slider 5 to move, thus moving the upper clamping block 6. The device is clamped to the edge of the cabinet and then activated by fan 11. The fan 11 draws air into the detection chamber 10, where it is detected by electrochemical sensor 14. The air is then expelled from the chamber and filtered through filter 12 to remove impurities. When the electrochemical sensor 14 detects carbon monoxide, a gas leak is detected, triggering an alarm 19. Remedial measures are then taken. After use, fan 11 is turned off, and screw 3 is rotated in the reverse direction. The screw causes the upper fixing plate 1 to move in the opposite direction, extending the telescopic rod 2. The length of the upper slider 5 is increased, causing the upper clamping block 6 to move in the opposite direction and disengage from the edge of the cabinet. The device can then be removed. In industrial applications, the device is removed by turning the fixing screw 7, followed by the clamping block 6. The device is then lifted, and depending on the pipe specifications, the fixing knob 8 is manually turned to disengage from the slider 5. The slider 5 is then pulled to a suitable position, and the fixing knob 8 is turned in the opposite direction to move it through the slider 5 for fixation. Anti-slip textures are used for anti-slip. The lower slider 5 then contacts the pipe. The above operation is repeated by turning the screw 3, causing the upper slider 5 to move and contact the pipe for clamping, thereby... This device is fixed to the pipeline. Then, the fan 11 is turned on to allow air to flow into the detection chamber 10. The gas is detected by the catalytic combustion sensor 13 and then discharged from the detection chamber 10. When the catalytic combustion sensor 13 detects methane, it indicates that there is a natural gas leak. At this time, the alarm 19 sounds to alert the user, and then remedial measures are taken. This allows for quick adjustment of the device's position to detect gas while providing early warnings. It is easy to quickly change positions to adapt to different environments and scenarios, improving detection efficiency and flexibility. After use, the fan 11 is turned off, and the above operation is repeated to remove the device. Before detecting a natural gas leak in a pipeline, depending on the detection location, the limiting block 16 can be manually pulled along the limiting plate 15 to disengage from the rotating plate 9. The spring 17 is compressed, and the right side of the limiting block 16 is C-shaped. Then, the detection chamber 10 is rotated, causing the rotating plate 9 to rotate, which in turn drives the fan 11 to rotate to the other side. After adjusting the angle, the limiting block 16 is released, the spring 17 rebounds, and the limiting block 16 moves back to its original position and engages with the rotating plate 9 for fixation. The above operation is then repeated to detect and warn of gas leaks. This allows the angle of the fan 11 to be adjusted according to the detection area to draw in air for detection, thereby expanding the detection coverage and improving detection accuracy.

[0034] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
