[0032] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0033] Example 1

[0034] See also Figure 1-5 As shown, in this embodiment, a sampling device is provided, which consists of a mounting frame 1, multiple gas storage tanks 2, a gas pipe 4, a regulating tank 6, an air pump 7, a hose 8, a sampling tube 9, a rotary joint 11, a connecting pipe 12, a switching assembly, and a locking assembly.

[0035] First, the mounting frame 1 serves as the supporting structure for the entire device. Multiple gas tanks 2 are fixedly mounted within it. Each gas tank 2 is fixedly connected to a gas pipe 4 at the top, which is used to direct the collected flue gas into the tank 2. To prevent flue gas backflow, each gas pipe 4 is equipped with a one-way valve 5.

[0036] A regulating tank 6 is fixedly mounted on the top of the mounting frame 1, and one end of a plurality of gas pipes 4 is fixedly connected to the outer wall of the regulating tank 6 and is in communication with the interior of the regulating tank 6. A switching assembly is provided inside the regulating tank 6, and the switching assembly includes a regulating core 13 that is sealed and rotatably provided inside the regulating tank 6. One end of the regulating core 13 is fixedly connected to the connecting pipe 12, and the other end of the connecting pipe 12 is in communication with the air outlet of the vacuum pump 7 via a rotary joint 11. In this way, when the vacuum pump 7 is working, the flue gas collected through the hose 8 and the sampling tube 9 can enter the interior of the regulating tank 6 via the rotary joint 11 and the connecting pipe 12, and be distributed to different gas pipes 4 through the air outlet 15 of the regulating core 13, and then enter the corresponding gas storage tank 2.

[0037] To achieve this switching function, the outer wall of the regulating core 13 is provided with multiple air outlet holes 15. These air outlet holes 15 are staggered in the radial direction of the regulating core 13 and respectively mate with multiple air delivery pipes 4 connected to the outer wall of the regulating tank 6. By rotating the regulating core 13, the alignment of the air outlet holes 15 with different air delivery pipes 4 can be changed, thereby achieving the switching of smoke delivery.

[0038] In order to ensure the stability of the regulating core 13, a locking assembly is also provided. The locking assembly includes a cylindrical shell 16 fixedly mounted on the end of the regulating tank 6 away from the connecting tube 12, and a gear holder 17 located in the cylindrical shell 16. A rotating rod 14 is fixedly mounted on one end of the regulating core 13, and the rotating rod 14 passes through the gear holder 17 and rotates through the cylindrical shell 16. A moving tube 19 and a gear block 18 are slidably sleeved on the outer wall of the rotating rod 14, and the two are fixedly connected, and the moving tube 19 and the gear block 18 can rotate synchronously with the rotating rod 14 through a slide block. One end of the moving tube 19 passes through one side of the cylindrical shell 16, and the gear block 18 engages with the gear holder 17 to achieve a locking function. In order to maintain the locked state, a spring 20 is sleeved on the outer wall of the moving tube 19, one end of which is in close contact with the inner wall of one side of the cylindrical shell 16, and the other end is in close contact with one side of the gear block 18.

[0039] The present application can be used in the field of flue gas sampling technology, and can also be used in other fields applicable to the present application.

[0040] Example 2

[0042] In order to facilitate observation of the rotational positions of the plurality of air outlet holes 15 , the regulating tank 6 is made of a transparent material.

[0043] For ease of operation, a first lever 21 is fixedly mounted on one end of the rotating rod 14 for rotating the adjusting core 13. Simultaneously, two corresponding second levers 22 are fixedly mounted on the outer wall of the movable tube 19. To unlock, the first and second levers 21, 22 are simultaneously operated to disengage the gear block 18 from the gear holder 17, thereby allowing the adjusting core 13 to rotate.

[0044] In addition, an exhaust pipe 3 with a valve is fixedly mounted on the outer wall of each gas storage tank 2 for discharging the smoke in the gas storage tank 2 when needed.

[0045] At the same time, a placement rack 10 is fixedly installed on one side of the installation frame 1 for placing the sampling tube 9.

[0046] In order to facilitate the movement of the entire device, four universal wheels 23 are fixedly installed on the bottom of the installation frame 1, and a push-pull handle 24 is fixedly installed on one side thereof.

[0047] The use process and working principle of the technical solution of this utility model are as follows:

[0048] When in use, the user can move the device to the position where smoke collection is required by pushing and pulling the handle 24 and the universal wheel 23. After that, the user can hold the first lever 21 with his hand and move the second lever 22 with his finger to pull the movable tube 19 outward. At this time, the gear block 18 is separated from the gear seat 17, and the user can rotate the rotating rod 14, which can drive the regulating core 13 to rotate synchronously; when the air outlet 15 on the outer wall of the regulating core 13 is aligned with the gas supply pipe 4 at one end of the gas storage tank 2 to be used, the rotation of the rotating rod 14 can be stopped at this time, and the pulling of the second lever 22 can be released. Under the action of the spring 20, the gear block 18 will be engaged with the gear seat 17 again, thereby completing the locking of the regulating core 13, which can ensure that the regulating core 13 has better stability during the gas supply process; after completing the adjustment of the regulating core 13, the user can remove the sampling tube 9, start the air pump 7, and collect The sampling tube 9 can sample and collect the external flue gas, and then the flue gas can be collected into the gas storage tank 2 through multiple connecting tubes 12 to complete the storage; the one-way valve 5 provided on the gas supply pipe 4 can prevent the flue gas from flowing back, thereby ensuring a good storage effect of the flue gas; when the user needs to sample another kind of flue gas, the user can rotate the adjustment core 13 again according to the above operation until the other air outlet 15 is aligned with the gas supply pipe 4 at one end of the other gas storage tank 2. At this time, the original air outlet 15 will be blocked and closed, and the other kind of flue gas can be collected into the other gas storage tank 2. The operation is simple and fast, which is convenient for users to use and effectively improves the efficiency of flue gas collection; when the user needs to take out the flue gas, he only needs to connect the external pipeline to the exhaust pipe 3 on one side of the corresponding gas storage tank 2. After opening the valve, the flue gas stored in the gas storage tank 2 can be discharged for subsequent analysis and detection.
