Description

Technical Field

[0001] The invention belongs to the technical field of environmental protection, and in particular relates to a sampling device for air monitoring in a radiation environment. Background Art

[0002] When conducting environmental testing, it is necessary to select appropriate sampling points and times, use sampling equipment to collect samples, and then send the samples to the laboratory to detect the components in the samples through analytical instruments; however, in some special use environments, such as nuclear reactors, the surrounding environment may be affected by radiation and become radioactive, so it is difficult for maintenance personnel to operate at close range for a long time. Therefore, in order to ensure the personal safety of maintenance personnel, a sampling device for air monitoring in radiation environments is needed, which can sample the air by itself;

[0003] After searching, the prior art publication number is CN117804849A, which is an automatic gas sampling device. The device controls the sample adding head structure and the propulsion component through the angle driving component to make the air enter the sample storage bottle through the air outlet pipe, the air guide pipe, the gas adding head, the plug, the second air vent and the first air vent in sequence; and drives the sample placement plate to rotate through the second motor to store samples in the sample storage bottles distributed along the circumferential direction of the sample placement plate; and the device cooperates with the hydrogen balloon arranged above the outer support shell through the hanging rope component at the bottom of the outer support shell to achieve air sampling at a high place; but the gas from the last sampling may remain in the air outlet pipe, the air guide pipe, the gas adding head, the plug, the second air vent and the first air vent, resulting in impure samples and affecting the accuracy of the monitoring data;

[0004] After searching, the prior art publication number is CN 118111772 A, which is a gas detection sampler. The device uses multiple external ports to evenly distribute the gas pipes at different positions in the space to be sampled and cooperates with the air pump to simultaneously draw the gas at different positions in the same space into the gas collection bottle; at the same time, when the air pump starts to pump gas forward, it can drive the valve block in the gas pipe to slide toward the straight pipe, so as to discharge the gas previously stored in the gas pipe into the gas collection tank; However, the device requires the staff to manually arrange the gas pipe, which is not suitable for use in dangerous environments;

[0005] Therefore, there is a need for a sampling device for air monitoring in a radiation environment, which can automatically perform sampling and replace the sampling bottle while preventing other gases from entering the sampling bottle and ensuring the accuracy of the sample data. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a sampling device for air monitoring in a radiation environment. The present invention realizes automatic replacement of sampling bottles by cooperating with a replacement device and a sampling device, thereby preventing the sampling bottle from colliding with the sampling device and causing damage, causing the sampling bottle to be unable to be used normally or the sample collected by the sampling bottle to leak; at the same time, the sampling of the sampling bottle is controlled by the negative pressure principle to prevent other gases from entering the sampling bottle and affecting the accuracy of the sample data.

The gas squeezes the rubber liner, thereby exhausting the air in the rubber liner; then buckle the sealing cover back to the air inlet at the bottom of the shell, open the inspection door on the storage box I, and fix the sampling bottle on the conveyor belt on the replacement device;

At the same time, the electric push cylinder IV cooperates with the pressure block II to control the clamping mechanism to drive the sampling bottle to extend toward the connecting plate. At this time, the pressure block I presses the sealing cover downward to open the air inlet at the bottom of the shell. At the same time, a closed space is formed between the sealing cover and the connecting box. Then the air pump is turned on to extract the air between the shell and the rubber liner, forming a negative pressure, so that the rubber liner starts to collect samples;

[0013] 5) Sealing: After sampling is completed, the threaded rod IV in the sealing device controls and drives the sealer to align with the connection port on the sampling bottle, and the electric push rod II controls the push block to buckle the sealing cover on the connection port on the sampling bottle. Then the electric push rod II controls the push block to reset, and the electric push rod II cooperates with the push rod to place the new sealing cover on one side of the push block;

[0014] 6) Collection of sampling bottles after sampling: The electric push cylinder IV in the sampling device drives the pressure block II to reset, and the spring I drives the support frame to reset; then the motor I in the replacement device drives the conveyor belt through the transmission roller to transport the unused sampling bottles to the top of the slide chute, and at the same time, an idle storage trough on the conveyor belt passes through the through trough II and rotates to the bottom of the discharge chute; then the rotating disk cooperates with the motor III to make the clamping mechanism drive the sealed sampling bottle to rotate to the top of the discharge chute; then the clamping mechanism drives the sampling bottle to descend, and the bottom of the sampling bottle passes through the discharge chute into the storage box II, then the transport mechanism II clamps the sampling bottle and drives the sampling bottle to continue to descend until the sampling bottle is inserted and rotated into the storage trough below the discharge chute;
