Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring, and more specifically, to a gas sampling device for environmental monitoring. Background Technology

[0002] Environmental monitoring refers to the activities of environmental monitoring agencies in monitoring and measuring the status of environmental quality. Environmental monitoring determines the level of environmental pollution and quality by monitoring and measuring indicators that reflect environmental quality. The content of environmental monitoring mainly includes the monitoring of physical indicators, chemical indicators, and ecosystems. Gas sampling devices are used in environmental monitoring when collecting gas samples.

[0003] A search revealed an existing patent (publication number: CN 211784629 U) that discloses a gas sampling device for environmental monitoring, relating to the technical field of auxiliary devices for environmental monitoring gas sampling. This patent addresses the problem that existing environmental monitoring gas sampling devices often increase the workload of staff because they cannot directly perform initial testing upon gas collection. The sampling housing has a cover plate on top, connected to the housing via a slot. A suction pipe placement slot is located in the middle of the cover plate, and a limit block is located at the lower end of the cover plate. A placement plate is located at the upper end of the sampling housing, and a sealing block is placed above the placement plate. An air pump is located inside the sampling housing and fixedly connected to the housing via an air pump support block. A suction pipe is located at the upper end of the air pump, with one end extending outside the suction pipe placement slot. A gas distributor is located at the lower end of the air pump. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Existing environmental monitoring gas sampling devices have poor sealing performance during the sampling process, which leads to the mixing of other gases during the gas input process or leakage during use, resulting in low accuracy of detection data. At the same time, existing devices cannot purify the remaining gas when sampling is not needed, which leads to gas sample mixing when used again.

[0005] Therefore, a gas sampling device for environmental monitoring is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a gas sampling device for environmental monitoring to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a gas sampling device for environmental monitoring, comprising a sampling box, wherein an auxiliary sampling mechanism is installed inside the sampling box;

[0008] The sampling box has a processing chamber embedded inside. A sampling tube is nested at the top of the sampling box, a pump body is nested at the bottom of the sampling tube, a bellows is nested at the bottom of the pump body, a fixing plate is fixedly installed at the bottom of the bellows, an injection tube is nested at the bottom of the fixing plate, a hydraulic rod is fixedly installed on one side of the top of the fixing plate, a first butyl rubber stopper is embedded inside the processing chamber, a gas storage tank is embedded at the bottom inside the sampling box, a second butyl rubber stopper is embedded at the top of the gas storage tank, an exhaust pipe is nested on one side of the outside of the gas storage tank, a gas meter is nested at the bottom of the gas storage tank, and a control panel is nested on the outside of the sampling box.

[0009] Furthermore, a filter screen is nested on the outside of the sampling tube, a heat dissipation window is embedded on the outside of the processing chamber, and activated carbon is embedded inside the heat dissipation window.

[0010] Furthermore, the pump body is nested between the sampling tube and the bellows.

[0011] Furthermore, the bellows is used in conjunction with the hydraulic rod.

[0012] Furthermore, the injection tube extends through the interior of the first butyl rubber stopper and the second butyl rubber stopper.

[0013] Furthermore, the gas meter is used in conjunction with the control panel.

[0014] Furthermore, the filter screen is movably mounted on the outside of the sampling tube.

[0015] Furthermore, there are two heat dissipation windows, distributed on both sides of the outer surface of the processing cavity.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. Compared with existing technologies, this environmental monitoring gas sampling device improves the accuracy of environmental gas detection by setting up an auxiliary sampling mechanism. The entire device is placed in the environment to be monitored. By activating the pump, gas from the environment to be tested is drawn in through the sampling tube. After passing through the pump, the gas is transmitted to the injection tube through the bellows. The fixed plate is then lowered by the hydraulic rod, allowing the injection tube to pass through the first and second butyl rubber stoppers, and the gas is input into the gas storage tank for storage. After the gas input is completed, the hydraulic rod compresses the injection tube, placing it in the processing chamber. At the same time, the gas meter automatically records and displays the volume or concentration of the gas in the storage tank. When gas needs to be discharged, it is discharged through the exhaust pipe. Multiple safety measures are taken during the sampling and discharge process to improve the sealing effect of gas collection, thereby improving the accuracy of gas detection.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] As attached Figure 1-4 The gas sampling device for environmental monitoring shown includes a sampling box 1, an auxiliary sampling mechanism 2 installed inside the sampling box 1, a processing chamber 3 embedded inside the sampling box 1, a sampling tube 4 nested at the top of the sampling box 1, a pump body 5 nested at the bottom of the sampling tube 4, a bellows 6 nested at the bottom of the pump body 5, a fixed plate 7 fixedly installed at the bottom of the bellows 6, an injection tube 8 nested at the bottom of the fixed plate 7, a hydraulic rod 9 fixedly installed on one side of the top of the fixed plate 7, a first butyl rubber stopper 10 embedded inside the processing chamber 3, a gas storage tank 11 embedded at the bottom inside the sampling box 1, a second butyl rubber stopper 12 embedded at the top of the gas storage tank 11, an exhaust pipe 13 nested on one side of the outside of the gas storage tank 11, a gas meter 14 nested at the bottom of the gas storage tank 11, and a control panel 15 nested on the outside of the sampling box 1.

[0026] The device is placed in the environment to be monitored. By activating the pump 5, gas from the environment is drawn in through the sampling tube 4. After passing through the pump 5, the gas is transmitted to the injection tube 8 through the bellows 6. The fixed plate 7 is then lowered by the hydraulic rod 9, allowing the injection tube 8 to pass through the first butyl rubber stopper 10 and the second butyl rubber stopper 12, thus inputting the gas into the gas storage tank 11 for storage. After the gas input is completed, it is compressed by the hydraulic rod 9, placing the injection tube 8 into the processing chamber 3. At the same time, the gas meter 14 automatically records and displays the volume or concentration of the gas in the gas storage tank 11. When gas needs to be discharged, it is discharged through the exhaust pipe 13. Multiple safety measures are taken during the sampling and discharge process to improve the sealing effect of gas collection, thereby improving the accuracy of gas detection.

[0027] Example 2

[0028] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with reference to the specific working method described in detail:

[0029] like Figure 1 As shown, in a preferred embodiment, a filter screen 16 is nested around the outside of the sampling tube 4, and a heat dissipation window 17 is embedded on the outer side of the processing chamber 3. Activated carbon 18 is embedded inside the heat dissipation window 17. Furthermore, the filter screen 16 allows the sampling tube 4 to be installed when gas collection is not required. The filter screen 16 filters the incoming gas, allowing the remaining gas inside the sampling tube 4 to be discharged. The gas is then discharged into the processing chamber 3 and purified by the heat dissipation window 17 and the activated carbon 18, improving the overall practicality of the device.

[0030] The working process of this utility model is as follows:

[0031] When using this environmental monitoring gas sampling device, firstly, place the entire device in the environment to be monitored. Then, start the pump 5 to draw in gas from the environment through the sampling tube 4. After passing through the pump 5, the gas is transmitted to the injection tube 8 via the bellows 6. The hydraulic rod 9 then controls the downward movement of the fixed plate 7, allowing the injection tube 8 to pass through the first butyl rubber stopper 10 and the second butyl rubber stopper 12, thus inputting the gas into the gas storage tank 11 for storage. After the gas input is complete, the hydraulic rod 9 compresses the gas, placing the injection tube 8 into the processing chamber 3. Simultaneously, the gas meter 14 automatically records and displays the data from the gas storage tank 11. The volume or concentration of gas inside the sampling tube 4 is measured. When gas needs to be discharged, it is discharged through the exhaust pipe 13. Multiple safety measures are taken during the sampling and discharge process to improve the sealing effect of gas collection, thereby improving the accuracy of gas detection. At the same time, the sampling tube 4 can be installed when gas collection is not required through the filter screen 16. The gas entering through the filter screen 16 is filtered to discharge the remaining gas inside the sampling tube 4. The gas is discharged into the processing chamber 3 and purified by the heat dissipation window 17 and activated carbon 18, improving the overall practicality of the device. This is the working process and working principle of the device.
