Description

Technical Field

[0001] This utility model belongs to the field of waste gas sampling technology, specifically relating to an automatic control sampling device. Background Technology

[0002] Waste gas sampling is a crucial step in environmental monitoring and industrial emission control. Its technical system and quality control directly affect the accuracy of environmental data. Generally, specialized sampling equipment is required for waste gas sampling. However, the concentration of gases varies in different environments, so it is necessary to sample gases from different environments. Staff extract and collect waste gases from different environments into appropriate devices for subsequent centralized testing. However, some existing sampling devices often have certain shortcomings in use, so they need to be improved.

[0003] Chinese patent CN216484201 U discloses an exhaust gas sampling device, comprising a main body with an air inlet seat and an exhaust gas monitoring mechanism mounted on its upper end. A tiered exhaust gas collection box is mounted on the upper end of the air inlet seat. A control panel is located at the front end of the main body, a bracket is mounted at the rear end, a push rod is mounted on the inner side of the bracket, a waste suction mechanism is mounted at the front end, and casters are located at the lower end. This utility model describes an exhaust gas sampling device with a tiered, identifiable exhaust gas collection box and a sealed air inlet valve seat, enabling convenient and better collection of exhaust gas. It features a tiered effect, collecting and identifying exhaust gas from different areas, allowing for detection and analysis of exhaust gas from each area. It also facilitates better entry of exhaust gas into individual exhaust gas boxes for easier air intake control and provides excellent sealing performance.

[0004] However, while the above-mentioned technical solution can achieve the purpose of sampling and collecting exhaust gas, the gas passes through the interior of the main body of the equipment during collection. Then, the staff pulls out the inlet valve plate, allowing the gas to enter one of the exhaust gas storage tanks. Afterwards, the staff manually closes the inlet valve plate. Because the inlet valve plate is equipped with a sealing gasket, its ability to move back and forth inside the inlet valve seat indicates that there is a certain gap between the inlet valve plate and the inlet valve seat. This causes the gas entering the exhaust gas storage tank to flow back. When other exhaust gas storage tanks contain gases of different concentrations, the gas inside the entire equipment will be mixed, thus affecting the subsequent detection results. Therefore, it has certain limitations in use. Utility Model Content

An electric slider 5 is slidably connected inside the electric slide rail 4. A support rod 6 is fixedly connected to the top of the electric slider 5. An electric telescopic rod 7 is fixedly connected to the top of the support rod 6. An insertion pipe 8 is fixedly connected to the output end of the electric telescopic rod 7. A contact plate 9 is fixedly connected to the surface of the insertion pipe 8. A first sealing ring 10 is provided on the top of the contact plate 9. Several storage cavities 11 are fixedly connected inside the placement cavity 2. An air inlet short pipe 12 is fixedly connected to the bottom of the storage cavity 11, and the surface of the air inlet short pipe 12 penetrates the interior of the housing 1. A control valve 13 is provided on the surface of the air inlet short pipe 12. A connecting plate 14 is fixedly connected to the bottom of the surface of the air inlet short pipe 12. A second sealing ring is provided at the bottom of the connecting plate 14. The electric slider 5 and electric slide rail 4 enable the support rod 6 to move left and right. The insertion pipe 8 allows it to be inserted into the air intake short pipe 12. The contact plate 9 ensures that the insertion pipe 8 contacts the connecting plate 14 when inserted into the air intake short pipe 12, thereby making the first sealing ring 10 and the second sealing ring contact, achieving a sealing effect during air intake. The control valve 13 can close the bottom end of the air intake short pipe 12 at the bottom of the storage chamber 11 to prevent the backflow of exhaust gas.

[0022] An exhaust fan 15 is fixedly connected to one side of the inner wall of the housing 1. An exhaust pipe is fixedly connected to the air inlet end of the exhaust fan 15, and an air inlet hood 16 is fixedly connected to the bottom end of the exhaust pipe. The air inlet hood 16 is fixedly connected to the middle of one side of the inner wall of the housing 1. An air supply pipe 17 is fixedly connected to the air outlet end of the exhaust fan 15, and the surface of the air supply pipe 17 penetrates the interior of the insertion pipe 8. Through the arrangement of the air inlet hood 16, the exhaust fan 15, the exhaust pipe, and the air supply pipe 17, exhaust gas can enter the interior of the insertion pipe 8, and then enter the interior of the storage chamber 11 through the short air inlet pipe 12.

[0023] An exhaust gas monitoring mechanism 22 is fixedly connected to one side of the top of the placement chamber 2. A second observation port 23 is opened on the surface of the housing 1, and a push handle 24 is fixedly connected to the other side of the housing 1. The exhaust gas monitoring mechanism 22 enables the exhaust gas to be monitored. The exhaust gas monitoring mechanism 22 can be an exhaust gas detector or other types of equipment in the prior art. The second observation port 23 facilitates the observation of the inside of the housing 1 by the staff, and the push handle 24 facilitates the movement of the housing 1 by the staff.

[0024] A control panel is fixedly connected to one side of the placement cavity 2, and the control panel is electrically connected to the electric slide rail 4, the electric telescopic rod 7, the control valve 13, the exhaust fan 15 and the exhaust gas monitoring mechanism 22 respectively.

[0025] Example 2:

[0026] Please see Figure 1 and Figure 3 As shown, a first observation port 18 is provided on the surface of the storage chamber 11, a label 19 is provided at the top of the surface of the storage chamber 11, and an extraction port 20 is fixedly connected to the top of the back of the storage chamber 11. A sealing plug 21 is threadedly connected to the surface of the extraction port 20. The first observation port 18 allows the operator to easily observe the internal condition of the storage chamber 11. The label 19 allows the operator to mark the current waste gas information inside the storage chamber 11. The extraction port 20 allows the operator to extract the waste gas from the storage chamber 11 for subsequent testing. The sealing plug 21 makes the extraction port 20 easy to seal.

[0027] The working principle of this utility model is as follows: When the operator needs to extract exhaust gas from the current location, they move the housing 1 to the appropriate position using the push handle 24, and then control the exhaust fan 15 to operate. The exhaust pipe at the air inlet of the exhaust fan 15 draws in air, transferring the suction force to the inside of the air inlet hood 16. The air then enters the inside of the air delivery pipe 17 through the air inlet pipe 3, and then enters the inside of the connector pipe 8 through the air delivery pipe 17. At the same time, the operator controls the electric slider 5 to slide inside the electric slide rail 4. The electric slider 5 then drives the support rod 6 to move left and right. When it moves to the position below the air inlet short pipe 12, the operator controls the electric slider 5 to operate. When the telescopic rod 7 is activated, the output end of the electric telescopic rod 7 drives the insertion pipe 8 to rise, so that it is inserted into the interior of the air intake short pipe 12. At the same time, the top of the contact plate 9 and the bottom of the connecting plate 14 come into contact, and the first sealing ring 10 and the second sealing ring come into contact, achieving a sealing effect. Then the exhaust gas enters the storage chamber 11. After a certain amount has entered, the operator controls the exhaust fan 15 and the control valve 13 to close. Then, a mark is made on the label 19 on the surface of the storage chamber 11 at the current position for subsequent testing. During subsequent testing, the sealing plug 21 can be opened, and a certain amount of exhaust gas can be extracted from the storage chamber 11 using the corresponding extraction mechanism for testing.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
