Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1 - Figure 2 , the present utility model provides a technical solution: an automatic acquisition device for a hazardous chemical accident site, including a main body mechanism 1. The main body mechanism 1 includes a carrier cart 101. A device box body 102 is fixedly installed at the upper end of the carrier cart 101. A gas storage tank body 103 is fixedly installed at the left end of the lower part inside the device box body 102. A gas storage tank inlet 104 is fixedly arranged at the upper end of the gas storage tank body 103. An electric switch valve at the inlet 105 is fixedly installed at the upper outer end of the gas storage tank body 103. A mechanical switch valve 106 of the gas storage tank is fixedly installed inside the gas storage tank body 103. A connecting hose 107 is movably connected to the upper end of the gas storage tank inlet 104. A liquid collection bottle 108 is fixedly installed at the right end of the lower part inside the device box body 102. The right end of the connecting hose 107 extends into the inside of the liquid collection bottle 108. A sampling tube 109 is movably installed inside the liquid collection bottle 108. The upper end of the sampling tube 109 extends above the liquid collection bottle 108. The right end of the sampling tube 109 is located outside the device box body 102. A liquid level sensor 110 is fixedly installed inside the liquid collection bottle 108.

[0023] A opening door 111 is movably installed at the right end of the device box body 102. A spring 112 is fixedly installed at the upper end of the transport trolley 101. The upper end of the spring 112 is fixedly connected to the opening door 111. A solenoid valve 113 is fixedly installed at the right end of the lower part inside the device box body 102. The solenoid valve 113 is located at the left end of the opening door 111. The solenoid valve 113 is movably connected to the opening door 111. A camera 114 is fixedly installed at the right end of the upper end of the transport trolley 101. An explosion-proof battery 115 is fixedly installed inside the device box body 102. A trolley track 116 is movably installed at the lower end of the transport trolley 101.

[0024] When using this device for the collection operation at the hazardous chemical accident site, the staff evacuates the gas storage tank body 103 to a vacuum state in the laboratory and closes the mechanical switch valve 106 of the gas storage tank. Connect the device according to the attached drawing at the sampling site and turn on the power. At this time, the inlet electric switch valve 105 is in the closed state, and the solenoid valve 113 is in the suction state. The solenoid valve 113 adsorbs the opening door 111, causing the spring 112 to be stretched, and the opening door 111 is in the closed state. After the device is placed, open the mechanical switch valve 106 of the gas storage tank and the camera 114, and remotely control the transport trolley 101 to drive the trolley track 116 to move, so that the transport trolley 101 moves to the target position, and then rotate the trolley to the appropriate sampling position. The above are the preparation work steps before the automatic collection of hazardous chemicals.

[0025] When using this device for the gas collection operation at the accident site, the staff remotely disconnects the power supply through remote control, causing the solenoid valve 113 to lose suction. The opening door 111 opens under the action of the pulling force of the spring 112, and the sampling tube 109 drops to above the target gas. At the same time, the inlet electric switch valve 105 is opened. Under the negative pressure state of the gas storage tank body 103, the air at the scene enters the liquid collection bottle 108 through the sampling tube 109, and then enters the gas storage tank body 103 through the connecting hose 107 to be collected, completing the gas collection work.

[0026] When using this device for the liquid collection operation at the accident site, the staff remotely disconnects the power supply through remote control, causing the solenoid valve 113 to lose suction. The opening door 111 opens under the action of the pulling force of the spring 112, and the sampling tube 109 drops below the liquid level. At the same time, the inlet electric switch valve 105 is opened. Under the negative pressure state of the gas storage tank body 103, the liquid at the scene enters the liquid collection bottle 108 through the sampling tube 109. When the liquid level in the liquid collection bottle 108 reaches the liquid level of the sensor 110, the inlet electric switch valve 105 is closed, completing the liquid collection work.

[0027] If it is necessary to collect both liquid and gas, one type of sample can be collected first, and then the position of the trolley can be moved to collect samples in another state. After the sampling is completed, the carrier trolley 101 can be remotely controlled back to the analysis area, the mechanical switch valve 106 of the gas storage tank can be closed, the connecting pipes can be removed, and the samples can be sealed for analysis.

[0028] Working principle: When using this device to collect samples at the scene of a hazardous chemical accident, the staff evacuates the gas storage tank body 103 to a vacuum state in the laboratory and closes the mechanical switch valve 106 of the gas storage tank. The device is connected according to the attached drawing at the sampling site and the power supply is turned on. At this time, the electric switch valve 105 at the air inlet is in the closed state, and the solenoid valve 113 is in the suction state. The solenoid valve 113 adsorbs the opening door 111, causing the spring 112 to be stretched and the opening door 111 to be in the closed state. After the device is placed, the mechanical switch valve 106 of the gas storage tank and the camera 114 are opened, and the carrier trolley 101 is remotely controlled to drive the trolley track 116 to move, so that the carrier trolley 101 moves to the target position, and then the trolley is rotated to a suitable sampling position. The above are the preparatory work steps before automatic collection of hazardous chemicals; when using this device to collect gas at the accident scene, the staff remotely disconnects the power supply through remote control, so that the solenoid valve 113 loses suction, and the opening door 111 opens under the action of the pulling force of the spring 112. The sampling tube 109 falls to above the target gas. At the same time, the electric switch valve 105 at the air inlet is opened. Under the negative pressure state of the gas storage tank body 103, the air at the scene enters the liquid collection bottle 108 through the sampling tube 109, and then enters the gas storage tank body 103 through the connecting hose 107 and is collected, completing the gas collection work; when using this device to collect liquid at the accident scene, the staff remotely disconnects the power supply through remote control, so that the solenoid valve 113 loses suction, and the opening door 111 opens under the action of the pulling force of the spring 112. The sampling tube 109 falls below the liquid level. At the same time, the electric switch valve 105 at the air inlet is opened. Under the negative pressure state of the gas storage tank body 103, the liquid at the scene enters the liquid collection bottle 108 through the sampling tube 109. When the liquid level in the liquid collection bottle 108 reaches the level of the sensor 110, the electric switch valve 105 at the air inlet is closed, completing the liquid collection work. If it is necessary to collect both liquid and gas, one type of sample can be collected first, and then the position of the trolley can be moved to collect samples in another state. After the sampling is completed, the carrier trolley 101 can be remotely controlled back to the analysis area, the mechanical switch valve 106 of the gas storage tank can be closed, the connecting pipes can be removed, and the samples can be sealed for analysis.
