Description

Technical Field

[0001] The present invention relates to the technical field of gas leakage alarm monitoring, and particularly to a gas leakage alarm monitoring device. Background Art

[0002] Gas is the general term for gaseous fuels, which can burn to release heat for use by residents and industrial enterprises. There are many types of gas, mainly including natural gas, artificial gas, liquefied petroleum gas, biogas, and coal gas.

[0003] Gas is an essential product in daily life and is also a very dangerous combustible gas. After gas leakage, gas will accumulate. When it reaches a certain amount and encounters an open flame, an explosion will occur, which is very dangerous. Currently, when a gas alarm is triggered, after obtaining the leakage data, it notifies indoor personnel to escape through sound and light alarm, and notifies relevant departments to come for handling through remote alarm. However, notifying indoor personnel to escape is too single. It should combine the leakage speed and concentration for on-site treatment or escape. If the leakage speed is slow and the danger level is low, on-site timely treatment can avoid the explosion caused by continuous leakage. If escaping in a timely manner when the leakage speed is slow, the concentration will continue to increase due to continuous accumulation, resulting in an explosion. Therefore, intelligent alarm for gas leakage is required. Summary of the Invention

[0058] The alarm mechanism 5 includes an audible and visual alarm 52 and a controller 51 fixed to one side of the U-shaped mounting frame 11. A second gas detection probe is installed outside the controller 51. The controller 51 is electrically connected to the audible and visual alarm 52, the first motor 236, the second motor 34, the first gas detection probe 238, the second gas detection probe and the distance sensor;

[0059] The alarm mechanism 5 prompts the indoor personnel in combination with the leakage speed and concentration, and remotely transmits the leakage data to the relevant departments for communication and rescue.

[0060] Working principle:

[0061] Install this device on the top of the gas meter in the cabinet, and install the air outlet cover 42 outdoors. When the second gas detection probe detects gas in the cabinet, the controller 51 controls the sound and light alarm 52 to alarm and remind people indoors, and then remotely transmits the gas leakage data to the gas management center;

[0062] Due to the density of the gas, the gas will accumulate at the top of the cabinet. At the same time, the controller 51 starts the second motor 34 to drive the exhaust fan blade 35 to rotate, and the air at the top of the cabinet is passed through the air inlet cover 32, the air inlet pipe 31, the first air inlet 211, and the second air inlet 26 opposite to the first air inlet 211 into the interior of the air chamber 24 connected to the second air inlet 26. After the gas enters the interior of the air chamber 24, it will push the piston plate 214 in the air chamber 24 to move. During the movement of the piston plate 214, the gas in the other air chamber 24 is discharged outdoors through the second air outlet 28, the first air outlet 210, the air outlet pipe 41, and the air outlet cover 42. During the movement of the piston plate 214, the spring 215 is compressed, and the mounting ring 217, the stirring rod 218, the first gas detection probe 238, and the magnet 219 are pulled to move synchronously. During the movement of the piston plate 214, the structures such as the first one-way gear 227 and the second one-way gear 232 are also driven to move synchronously. When moving in this direction, the rotation generated by the engagement of the first one-way gear 227 and the first rack 228 does not meet the rotation direction for driving the second rotating shaft 226. Therefore, the sealing block 222 still blocks the third air outlet 221. The blockage causes the piston plate 214 to form a piston, which is pushed by the incoming gas and moves in the air chamber 24, and the gas on the other side is pushed out;

[0063] When the gas enters, it will cause the fan blade 220 to drive the first rotating shaft 212 and multiple magnetic strips 213 to rotate. The rotation of the magnetic strips 213 drives the stirring rod 218 to rotate through the magnet 219, dispersing the incoming gas and avoiding the poor accuracy of the detection data caused by aggregation due to density reasons;

[0064] When the piston plate 214 moves, the distance sensor obtains the moving distance of the piston plate 214. When it moves to the specified distance, the controller 51 starts the first motor 236 to drive the second gear 237 to rotate, so that the first gear 235 drives the cylinder 23 to rotate. The cylinder 23 drives the first end plate 25 and the second end plate 27 to rotate. At the same time, the structure in the air chamber 24 rotates accordingly. At this time, the second air inlet 26 is offset from the first air inlet 211, and the second air outlet 28 is offset from the first air outlet 210, making the inside of this air chamber 24 sealed. When the piston plate 214 moves to the specified distance, the one-way gear two 232 meshes with the rack two 234. The rotation direction generated by the meshing of the one-way gear two 232 and the rack two 234 in this moving direction satisfies the rotation direction for driving the third rotating shaft 231 to rotate. The third rotating shaft 231 drives the fourth bevel gear 233 to rotate. The fourth bevel gear 233 drives the third bevel gear 229 and the reciprocating screw 223 to rotate, so that the first moving plate drives the sealing block 222 to move, opening the third air outlet 221. After the third air outlet 221 is opened, a gap appears in the piston plate 214, and the spring 215 can then push the piston plate 214 to move back to one side. When moving, the sucked gas passes through the third air outlet 221 and enters the other side of the piston plate 214. During the movement of the piston plate 214, the first gas detection probe 238 detects the mixed gas, obtains the concentration value under the specified gas volume, and transmits it to the controller 51. When the piston plate 214 is reset, the one-way gear one 227 meshes with the rack one 228 and rotates. The rotation direction of the one-way gear one 227 satisfies the rotation direction for driving the second rotating shaft 226 to rotate, thereby driving the second bevel gear 239 to rotate. The second bevel gear 239 drives the first bevel gear 224 and the reciprocating screw 223 to rotate, so that the first moving plate drives the sealing block 222 to reset and insert into the inside of the third air outlet 221, blocking the third air outlet 221, and making the piston plate 214 form a complete piston, waiting for the next gas suction;

[0065] After the controller 51 obtains the concentration value, it judges the leakage speed of the gas leakage location according to this concentration value. Then the controller 51 remotely transmits the leakage data to the gas management center, and broadcasts voice through the sound and light alarm 52 according to the gas leakage speed, and issues an operation instruction to remind the indoor personnel to quickly evacuate or quickly close the main gas valve according to the leakage speed. After the gas management center obtains the data, it communicates and processes with multiple departments and gas-using households;

[0066] When multiple air chambers 24 are sequentially rotated for detection, the gas in the cabinet is continuously sucked in. When the detected air chamber 24 is reconnected to the first air inlet 211 and the first air outlet 210, the new gas entering will pass through the piston plate 214 to discharge the detected gas on the other side through the air outlet pipe 41 and the air outlet cover 42 to the outside of the room. Extracting and detecting the leaked gas and discharging it to the outside of the room can reduce the indoor gas concentration and delay the speed of gas concentration superposition, providing time for later rescue and escape.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
