Description

Technical Field

[0001] The present invention belongs to the technical field of gas detection, and in particular relates to a safe and environmentally friendly gas detection device and method. Background Art

[0002] When performing daily operations such as confined space operations (aircraft wing tank cleaning operations, aviation fuel depot cleaning operations, waste emulsion cleaning operations), whole machine painting operations, etc., a large amount of toxic and harmful gases will be generated, mainly involving carbon monoxide, hydrogen sulfide, methane, etc. Therefore, it is necessary to ensure that the working environment is safe before the operators can carry out subsequent inspections and maintenance operations. If the protective measures or management measures are not implemented in place, the health of the operators will be seriously threatened. Therefore, it is usually necessary to test the environmental gases before the operation.

[0003] However, in the existing gas detection method, workers usually need to wear protective clothing, protective masks and other protective measures, and use a gas concentration detector to detect the gas concentration in the workplace. This method has low detection efficiency. At the same time, the existing detection method requires manual sampling of the gas in advance. However, when this method is used, the sealing of the sampling device is poor, which causes sample loss. At the same time, the gas sample will be neutralized by the air in the environment, resulting in low detection accuracy. At the same time, the detection efficiency is low due to multiple reciprocating sampling and detection work. At the same time, the existing detection method needs to rely on a large amount of manpower, resulting in poor detection effect. For this reason, the present invention proposes a safe and environmentally friendly gas detection device and method to solve the problems of low detection efficiency and low monitoring accuracy of existing equipment.

[0014] The present invention also provides a safe and environmentally friendly gas detection method, based on the safe and environmentally friendly gas detection device as described above, comprising the following steps:

[0015] Step 1: Before using this equipment, the staff will position multiple sampling tubes inside the test box through multiple sets of main clamping rings and auxiliary clamping rings, and fix the detector on the top of the positioning plate. At this time, the staff will seal the box door and the test box through two buckles to ensure the sealing of the entire equipment. The controller will then control the detector and the test head to start working, and the gas situation inside the test box can be further detected. The controller will then control the oxygen pump and the oxygen supply valve to work, and the outlet solenoid valve to work, so that the oxygen inside the oxygen supply tank is filled into the test box, thereby ensuring that the value of the detector remains stable before the test.

[0016] Step 2: The controller further controls the two mobile motors to work in coordination, thereby driving the two mobile gears to rotate, and then driving the two crawlers to rotate in coordination, so that the entire device can move and turn at the same time, and the movement status can be monitored by a mobile camera;

[0017] Step 3: When the whole device moves to the required gas detection position, the controller controls the reversing motor and the moving rod controller to work together, so that the moving rod can be rotated and retracted at the same time, so that the collecting head can be turned and moved up and down at the same time, so that the collecting head can reach the required position. At this time, the specific position of the collecting head can be monitored due to the function of the collecting camera;

[0018] Step 4: The controller further controls the support motor to rotate the support main gear, thereby driving the support sub-gear to rotate, and then driving the support rod to rotate, and at the same time controls the support rod controller to extend and retract the support rod, so that the sampling tube can reach the top of the gas outlet plate, and further controls the sampling tube to descend, so that the gas outlet plate pushes the sealing plate to move upward until the sealing ring is tightly attached to the sealing plate, so that the sampling tube is sealed;

[0019] Step 5: The controller further controls the collection pump and the collection valve to work simultaneously, so as to deliver the gas to the booster pipe, and then deliver it to the inside of the sampling tube through the outlet pipe. At this time, the excess gas inside the sampling tube is discharged through the clamping rod. At this time, the detection head transmits the detection data to the detector. At this time, the detector transmits the value to the controller and records it. When the value of the detector is stable, the controller controls the collection valve and the collection pump to stop working. The controller further controls the sampling tube to reset. The controller further controls the detection head to be inserted into the injection head, so as to perform the detection work again, so as to ensure the authenticity of the detection data. The controller further controls the injection valve to be closed, so as to save the gas, so as to ensure the subsequent secondary detection.

[0020] Step six: The controller further controls the oxygen to enter the detection box again, so that the detection box is filled with oxygen again, thereby resetting the detector data, and the controller further controls the device to move to the next position, thereby facilitating the detection work at the next position.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] This equipment can pump oxygen from the oxygen supply tank into the test box through the cooperation of the oxygen pump and the oxygen supply valve, and can discharge the gas inside the test box through the exhaust solenoid valve, so that the test box is filled with oxygen before the test, so that the value of the detector is fixed before the test, thereby ensuring the accuracy of the test and thus ensuring the test effect;

[0023] This equipment can rotate the reversing main gear through the cooperation of the reversing motor and the moving rod controller, thereby driving the reversing sub-gear to rotate, thereby driving the moving rod to rotate, and at the same time driving the moving rod to extend and retract, thereby driving the collecting head to move up and down and turn at the same time, so that the collecting head can reach any position, thereby further ensuring the accuracy of the detection. At the same time, this equipment can transport the gas to the outlet pipe through the booster pipe through the collection valve and the collection pump, and then transport it to the inside of the sampling tube, thereby realizing automation and improving the detection efficiency;

[0024] This equipment can drive the support main gear to rotate through the support motor, thereby driving the support sub-gear to rotate, thereby driving the support rod to rotate, and then through the support rod controller, the support rod can be driven to extend and retract, so that the support plate can move up and down and turn at the same time, so that the sampling tube can be located at the top of the outlet pipe, thereby ensuring the accuracy of gas entering the sampling tube, thereby further ensuring the detection effect;

[0025] This device can drive the vertical moving rod to extend and retract through the vertical moving controller, thereby driving the front and rear moving rod to move up and down. At the same time, the front and rear moving rods can be driven to extend and retract through the front and rear moving controller, thereby driving the detection head to move, thereby ensuring that the detection head can be inserted into the interior of the jet head directly opposite it, thereby further ensuring the detection accuracy, thereby further ensuring the detection effect;

[0026] The device can drive the sampling rod to descend by contracting the support rod, thereby driving the sampling tube to descend, so that the gas outlet pipe lifts the sealing disk, and at the same time makes the sealing ring and the sampling head fit tightly, thereby preventing gas leakage, and at the same time ensuring that the oxygen inside the detection box enters the sampling tube, thereby ensuring the purity of the gas inside the sampling tube, thereby further ensuring the accuracy of the detection.

Step six: the controller (103) further controls the oxygen to enter the detection box (106) again, so that the detection box (106) is filled with oxygen again, so that the data of the detector (9) is reset, and the controller (103) further controls the device to move to the next position, so as to facilitate the detection work at the next position.
