Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of gas detection, and specifically relates to a safe and environmentally-friendly gas detection device and method. BACKGROUND

[0002] In daily operations such as limited space operation (aircraft wing tank cleaning operation, aviation fuel tank cleaning operation, waste emulsion cleaning operation), whole machine paint spraying operation, etc., a large amount of toxic and harmful gas will be generated, mainly involving carbon monoxide, hydrogen sulfide, methane, etc., so the operating personnel can only carry out subsequent maintenance and maintenance operations after ensuring the safety of the operating environment. When protective measures or management measures are not properly implemented, the health of the operating personnel will be seriously threatened. Therefore, the environmental gas needs to be detected before operation.

[0003] However, the existing gas detection method usually requires the operating personnel to wear protective clothing, protective masks and other protective measures, and uses a gas concentration detector to detect the gas concentration of the operating site. This method has low detection efficiency. At the same time, the existing detection method needs to manually sample the gas in advance. However, this method has poor sealing performance of the sampling device when in use, so that the sample is lost, and the gas sample is neutralized by the air in the environment, thereby reducing the detection accuracy. At the same time, the detection efficiency is low due to the repeated sampling and detection work, and the existing detection method needs to rely on a large amount of manual work, thereby reducing the detection effect. Therefore, the application provides a safe and environmentally-friendly gas detection device and method to solve the problems of low detection efficiency and low monitoring accuracy of the existing equipment.

2. A safe and environmentally friendly gas detection method, based on the safe and environmentally friendly gas detection device according to claim 1, characterized in that: Includes the following steps: Step 1: Before using this equipment, the staff will position multiple sampling tubes (8) inside the detection box (106) through multiple sets of main clamping rings (607) and auxiliary clamping rings (608), and fix the detector (9) on the top of the positioning plate (502). At this time, the staff will use two buckles (104) to seal the door (101) and the detection box (106) to ensure the airtightness of the entire equipment. Then, the controller (103) will control the detector (9) and the detection head (901) to start working, and can further detect the gas situation inside the detection box (106). The controller (103) will control the oxygen pump (301) and the oxygen supply valve (302) to work, and at the same time control the gas outlet solenoid valve (303) to work, so as to fill the oxygen in the oxygen supply tank (3) into the detection box (106), thereby ensuring that the value of the detector (9) remains stable before detection. Step 2: The controller (103) further controls the two moving motors (203) to work together, thereby driving the two moving gears (201) to rotate, which in turn drives the two tracks (2) to rotate, thus enabling the entire equipment to move and turn at the same time. The movement can be monitored by the moving camera (105). Step 3: When the entire device moves to the location of the gas to be detected, the controller (103) controls the reversing motor (405) and the moving rod controller (402) to work together, thereby driving the moving rod (4) to rotate and extend, thereby driving the collecting head (401) to turn and move up and down, so that the collecting head (401) can reach the required position. At this time, due to the function of the collecting camera (409), the specific position of the collecting head (401) can be monitored. Step 4: The controller (103) further controls the support motor (701) to make the support main gear (7) rotate, thereby driving the support secondary gear (703) to rotate, and then driving the support rod (704) to rotate. At the same time, the controller (705) controls the support rod to extend and retract, so that the sampling tube (8) can reach the top of the air outlet plate (417). The controller further controls the sampling tube (8) to descend, so that the air outlet plate (417) pushes the sealing plate (809) to move upward until the sealing ring (810) is tightly attached to the sealing plate (415), thereby sealing the sampling tube (8). Step 5: The controller (103) controls the collection pump (411) and collection valve (413) to work simultaneously, thereby delivering the gas to the booster pipe (414), and then through the outlet pipe (418) to the inside of the sampling tube (8). At this time, the excess gas inside the sampling tube (8) is discharged through the clamping rod (505). At this time, the detection head (901) transmits the detection data to the detector (9). At this time, the detector (9) transmits the value to the controller (103) and records it. When the value of the detector (9) is stable, the controller (103) controls the collection valve (413) and collection pump (411) to stop working. The controller (103) controls the sampling tube (8) to reset. The controller (103) controls the detection head (901) to insert into the jet nozzle (805) to perform the detection work again, thereby ensuring the authenticity of the detection data. The controller (103) controls the jet valve (806) to close, thereby saving the gas and ensuring the subsequent secondary detection. Step 6: The controller (103) controls the oxygen to re-enter the detection chamber (106), thereby filling the detection chamber (106) with oxygen again, thereby resetting the data of the detector (9), and the controller (103) controls the equipment to move to the next position, thereby facilitating the detection work at the next position.
