Description

Technical Field

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

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

[0003] Gas is an indispensable product in daily life and is also a very dangerous flammable gas. Gas leakage will lead to gas accumulation. When it reaches a certain amount, it will explode when it encounters an open flame. It is very dangerous. The current gas alarm is to obtain the leakage data and then notify the indoor personnel to escape through sound and light alarm, and notify the relevant departments to deal with it through remote alarm. However, notifying the indoor personnel to escape is too simple. On-site processing or escape should be carried out in combination with the leakage speed and concentration. If the leakage speed is slow, timely on-site processing when the danger is low can avoid the explosion caused by continuous leakage. If the leakage speed is slow and the person escapes in time, the concentration will continue to increase due to continuous accumulation, resulting in an explosion. Therefore, gas leakage requires intelligent alarm. Summary of the invention

A gas detection probe 2 is installed outside the controller 51. The controller 51 is electrically connected to the audible and visual alarm 52, the motor 1 236, the motor 2 34, the gas detection probe 1 238, the gas detection probe 2 and the distance sensor; The alarm mechanism 5 reminds the indoor personnel based on the leakage speed and concentration, and remotely transmits the leakage data to the relevant departments for communication and rescue.

[0030] Working principle: The device is installed on the top of the cabinet where the gas meter is located, and the gas outlet cover 42 is installed outdoors. When the gas detection probe 2 detects the presence of gas in the cabinet, the controller 51 controls the sound and light alarm 52 to alarm and remind people in the room, and then remotely transmits the gas leakage data to the gas management center; Due to the density of the gas, the gas will gather on the top of the cabinet. At the same time, the controller 51 starts the motor 2 34 to drive the exhaust fan blades 35 to rotate, and the air on the top of the cabinet enters the interior of the air chamber 24 connected to the air inlet 26 through the air inlet hood 32, the air inlet pipe 31, the air inlet 1 211 and the air inlet 26 opposite to the air inlet 1 211. After the gas enters 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 air chamber 24 on the other side will be discharged to the outside through the air outlet 2 28, the air outlet 1 210, the air outlet pipe 41 and the air outlet hood 42. The piston plate 214 During the movement, the spring 215 is compressed, and the mounting ring 217, the stirring rod 218, the gas detection probe 1 238 and the magnetic block 219 are pulled to move synchronously. During the movement of the piston plate 214, the one-way gear 1 227 and the one-way gear 2 232 and other structures are also driven to move synchronously. When moving in this direction, the rotation generated by the meshing of the one-way gear 1 227 and the rack 1 228 does not meet the direction of driving the rotation of the rotating shaft 226, so the sealing block 222 is still in a blocking state with respect to the gas outlet 3 221. The blocking makes the piston plate 214 form a piston, which is pushed by the incoming gas to move in the gas chamber 24 and push out the gas on the other side. When the gas enters, the fan blades 220 drive the rotating shaft 212 and the plurality of magnetic strips 213 to rotate. The rotation of the magnetic strips 213 drives the stirring rod 218 to rotate through the magnetic block 219, thereby dispersing the incoming gas and avoiding the situation where the detection data has poor accuracy due to the gas gathering together due to density reasons. When the piston plate 214 moves, the distance sensor obtains the distance moved by the piston plate 214. When it moves to the specified distance, the controller 51 starts the motor 1 236 to drive the gear 2 237 to rotate, so that the gear 1 235 drives the column 23 to rotate, and the column 23 drives the end plate 1 25 and the end plate 27 to rotate. At the same time, the structure in the air chamber 24 rotates accordingly. At this time, the air inlet 26 is staggered with the air inlet 1 211, and the air outlet 28 is staggered with the air outlet 1 210. The internal seal of the air chamber 24, when the piston plate 214 moves to a specified distance, the one-way gear 232 meshes with the rack 234, and the direction of rotation generated by the meshing of the one-way gear 232 and the rack 234 in this moving direction satisfies the direction of rotation of the rotating shaft 3 231, the rotating shaft 3 231 drives the bevel gear 4 233 to rotate, and the bevel gear 4 233 drives the bevel gear 3 229 and the reciprocating screw 223 to rotate, so that the moving plate 1 drives the sealing block 222 to move, and the air outlet When the piston plate 214 is moved, the gas detection probe 1 238 detects the mixed gas, obtains the concentration value of the gas under the specified volume, and transmits it to the controller 51. When the piston plate 214 is reset, the one-way gear 1 227 meshes with the rack 1 228 and rotates. The rotation direction of the one-way gear 1 227 meets the direction of driving the rotation shaft 226 to rotate, thereby driving the bevel gear 239 to rotate. The bevel gear 239 drives the bevel gear 1 224 and the reciprocating screw 223 to rotate, so that the moving plate 1 drives the sealing block 222 to reset and insert into the interior of the gas outlet 3 221, and the gas outlet 3 221 is blocked, so that the piston plate 214 is combined into a piston, waiting for the next gas to be drawn in. After the controller 51 obtains the concentration value, it determines the leakage speed of the gas leakage location according to the concentration value. Then, the controller 51 remotely transmits the leakage data to the gas management center, and broadcasts voice according to the gas leakage speed through the sound and light alarm 52, and issues an operating instruction to remind indoor personnel to evacuate quickly or quickly close the main gas valve according to the leakage speed. After obtaining the data, the gas management center communicates with multiple departments and gas households for processing; When multiple air chambers 24 rotate for detection in sequence, the gas in the cabinet is continuously drawn in. When the detected air chamber 24 is re-connected with the air inlet 211 and the 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 hood 42 to the outside. Extracting and detecting the leaked gas and discharging it outdoors can reduce the indoor gas concentration, slow down the speed of gas concentration superposition, and provide time for later rescue and escape.
