DETAILED DESCRIPTION

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] Please also refer to Figure 1 and Figure 2, the automatic smoke sampling quality control device provided by the present invention is now described. The automatic smoke sampling quality control device includes an installation shell 1, a first accommodating chamber 2 for accommodating an unused sampling module 13, a second accommodating chamber 3 connected to the interior of the installation shell 1 for accommodating the used sampling module 13, and a telescopic transport member 4 movably arranged in the installation shell 1 for pushing out or retracting the sampling module 13 into the installation shell 1. The telescopic transport member 4 is also provided with a plug-in unit 5 for plugging and fixing with the sampling module 13. The plug-in unit 5 connects the sampling module 13 with the external exhaust pipeline and the external circuit. The installation shell 1 is also provided with a card-mounted transport mechanism 6. The card-mounted transport mechanism 6 plugs and fixes the sampling module 13 that enters the installation shell 1 from the first accommodating chamber 2 with the plug-in unit 5, and transports the sampling module 13 to the entrance of the second accommodating chamber 3 after sampling.

[0029] Compared with the prior art, the automatic smoke sampling quality control device provided in this embodiment fixes the installation shell 1 on the side wall flange of the flue or chimney before smoke sampling. A telescopic transport member 4 is provided inside the installation shell 1, and a plug-in unit 5 is provided on the telescopic transport member 4 to be plugged and fixed with the sampling module 13. A first accommodating chamber 2 for accommodating an unused sampling module 13 and a second accommodating chamber 3 connected to the inside of the installation shell 1 for accommodating a used sampling module 13 are provided on the side of the installation shell 1. Multiple sampling modules 13 are placed side by side in the first accommodating chamber 2 in sequence. When smoke sampling is performed, the sampling module 13 closest to the mounting shell 1 in the first accommodating chamber 2 enters the mounting shell 1 from the first accommodating chamber 2 and is fixed to the mounting transport mechanism 6 by card-fitting. Then the telescopic transport part 4 extends toward the direction close to the sampling module 13. The plug-in unit 5 on the telescopic transport part 4 is plugged and fixed to the connecting terminal 136 and the exhaust port 135 on the sampling module 13. The sampling module 13 is connected to the external exhaust pipeline and the external circuit of the equipment through the plug-in unit 5. Then the mounting transport mechanism 6 is disengaged from the sampling module 13. The telescopic transport part 4 continues to move to push the sampling module 13 into the flue or chimney to collect smoke. After the collection is completed, the telescopic transport member 4 moves in the opposite direction to the initial position of the sampling module 13, and the clamping transport mechanism 6 re-clamps the sampling module 13. The telescopic transport member 4 continues to move in the opposite direction to disengage the plug-in unit 5 from the sampling module 13. Finally, the clamping transport mechanism 6 transports the sampling module 13 to the second accommodating chamber 3 to complete the smoke sampling. The smoke automatic sampling quality control device of the present invention can realize the action of transporting the sampling module 13 from the first accommodating chamber 2, sampling, and then re-transporting it to the second accommodating chamber 3 through the cooperation of the clamping transport mechanism 6 and the telescopic transport member 4, fully realizing the automatic replacement of the module.

[0030] In this embodiment, the sampling module 13 is an integral unit consisting of a protective shell disposed outside a standard sampling head and a standard sampling head 138. It includes a housing 131, a mounting member 132 disposed inside the housing 131 for mounting the sampling head, and an exhaust cavity 133 whose mouth is connected to the gas outlet of the sampling head 138. The mounting member 132 presses and secures the sampling head 1313 to the mouth of the exhaust cavity 133. The exhaust cavity 133 is also provided with an exhaust port 135 for communicating with an exhaust device for discharging gas from the exhaust cavity 133. A heating unit 134 for heating the filter membrane on the sampling head is also provided within the housing 131. The heating unit 134 includes a plurality of heating elements disposed around the sampling head, and a connection terminal 136 disposed within the housing 131 and electrically connected to the heating element. The plug-in unit 5 arranged on the telescopic transport member 4 is a block as a whole. The plug-in unit 5 is provided with a connecting terminal 136 that cooperates with the connecting terminal 136. The plug-in unit 5 is also provided with a connecting pipe for connecting with the air suction port 135, and the plug-in unit 5 is also provided with a positioning pin that matches the position and size of the positioning hole on the accommodating shell 131 of the sampling module 13.

[0031] In addition, in this embodiment, the first accommodating chamber 2 can be set vertically or tilted, and multiple sampling modules 13 are arranged in sequence in the first accommodating chamber 2 so that the sampling modules 13 can slide into the mounting shell 1 along the length direction of the first accommodating chamber 2 by their own gravity. The second accommodating chamber 3 is generally set at an angle, so that the sampling modules 13 can slide to the bottom of the second accommodating chamber 3 by gravity after entering the second accommodating chamber 3 under the transportation of the card-mounted transport mechanism 6, making the storage of the sampling modules 13 more convenient. In addition, the bottoms of the first accommodating chamber 2 and the second accommodating chamber 3 are both provided with a clearance groove that is compatible with the external protrusion of the sampling module 13. The clearance groove and the external protrusion of the sampling module 13 can cooperate with each other to make the sliding of the sampling module 13 more stable, thereby preventing the sampling module 13 from rolling or tilting.

[0032] As a specific embodiment of the smoke dust automatic sampling quality control device provided by the present invention, please refer to Figure 3The clamping and transporting mechanism 6 includes a movable transport part 61 provided in the mounting shell 1 for clamping and fixing the sampling module 13, a linear drive unit 62 for driving the movable transport part 61 to move, and a push-off structure 63 provided at the mouth of the second accommodating chamber 3 for pushing the sampling module 13 from the movable transport part 61 to the second accommodating chamber 3. After the sampling module 13 enters the mounting shell 1 from the first accommodating chamber 2, the movable transport part 61 is used to accommodate the sampling module 13, and then the telescopic transport part 4 moves close to the plug-in unit 5 on the telescopic transport part 4 and is plugged and fixed with the connecting terminal 136 and the exhaust port 135 on the sampling module 13. The sampling module 13 is connected to the external exhaust pipeline and the external circuit of the equipment through the plug-in unit 5. Then, the movable transport part 61 is driven by the linear drive mechanism to separate from the sampling module 13, and the telescopic transport part 4 continues to move to push the sampling module 13 out into the flue or chimney to collect smoke and dust. After the collection is completed, the telescopic transport part 4 moves in the opposite direction to the initial position of the sampling module 13, and the movable transport part 61, driven by the linear drive mechanism, re-clamps the sampling module 13 in the clamping structure on the movable transport part 61. The telescopic transport part 4 continues to move in the opposite direction to disengage the plug-in unit 5 from the sampling module 13. Finally, the movable transport part 61 transports the sampling module 13 to the mouth of the second accommodating chamber 3, and then pushes the sampling module 13 into the second accommodating chamber 3 through the push-off structure 63, and stores the used sampling module 13. The linear drive unit 62 drives the movable transport part 61 to move between the outlet of the first accommodating chamber 2 and the entrance of the second accommodating chamber 3 to transport the sampling module 13, making the transportation, movement, disassembly and replacement of the sampling module 13 in the installation shell 1 more convenient.

[0033] Moreover, the movable transport part 61 can also cooperate with the telescopic transport part 4 through movement to realize the connection and disconnection of the sampling module 13 and the plug-in unit 5. After the sampling module 13 enters the installation shell 1 from the first accommodating chamber 2, the sampling module 13 is first clamped onto the movable transport part 61, and then the telescopic transport part moves close to the plug-in unit 5 on the telescopic transport part 4 and is plugged and fixed with the connecting terminal 136 and the air extraction port 135 on the sampling module 13. The sampling module 13 is connected to the external air extraction pipeline and the external circuit of the equipment through the plug-in unit 5. Then, the movable transport part 61 is disconnected from the sampling module 13 under the drive of the linear drive mechanism, and the telescopic transport part 4 continues to move to push the sampling module 13 into the flue or chimney to collect smoke dust. After the collection is completed, the telescopic transport part 4 moves in the opposite direction to the initial position of the sampling module 13. The movable transport part 61, driven by the linear drive mechanism, re-clamps the sampling module 13 in the clamping structure on the movable transport part 61. The telescopic transport part 4 continues to move in the opposite direction to disengage the plug-in unit 5 from the sampling module 13. Finally, the movable transport part 61 transports the sampling module 13 to the mouth of the second accommodating chamber 3, and then pushes the sampling module 13 out into the second accommodating chamber 3 to store the used sampling module 13.

[0034] As a specific embodiment of the smoke dust automatic sampling quality control device provided by the present invention, please refer to Figure 2 and Figure 3 The movable transport member 61 is a movable card plate, which is provided with a through-slot for receiving and retaining the sampling module 13. A plurality of guide slides 64 are provided within the inner ring of the mounting housing 1 and extend through the movable card plate. A first mounting plate 15 for mounting the guide slides 64 is also provided within the mounting housing 1. Driven by the linear drive mechanism, the movable transport member 61 slides along the length of the guide slides 64. The plurality of guide slides 64 ensures smoother sliding of the movable transport member 61.

[0035] In this embodiment, the first accommodating chamber 2 and the second accommodating chamber 3 are both located on the side of the mounting shell 1, and the entrance of the second accommodating chamber 3 is located below the exit of the first accommodating chamber 2. A plurality of guide slides 64 are vertically arranged in the mounting shell 1. A holding groove for accommodating the sampling module 13 is provided on the upper surface of the movable transport member 61. A clearance opening for the sampling module 13 to pass through is also provided on the side of the holding groove near the exit of the first accommodating chamber 2, so as to facilitate the sampling module 13 to enter and exit the holding groove. A clearance opening is also provided on the side of the holding groove near the plug-in unit 5. A fixing groove for fixing the sampling module 13 in the axial direction of the telescopic transport member 4 is provided at the bottom of the holding groove. In addition, a clearance groove for the ejection plate 631 to pass through is provided at the bottom of the holding groove, so as to facilitate the ejection structure 63 to push the sampling module 13 out of the clearance opening of the holding groove and push it into the second accommodating chamber 3 for storage.

[0036] In this embodiment, the linear drive mechanism includes a rotating screw that passes through and is threadedly connected to the movable transport member 61, and a motor for driving the rotating screw. The rotating screw and the plurality of guide slides 64 are arranged parallel to each other. The motor is electrically connected to a controller, which controls the start, stop, and rotation of the motor. The motor is preferably a servo motor or a stepper motor.

[0037] As a specific embodiment of the smoke dust automatic sampling quality control device provided by the present invention, please refer to Figure 2 and Figure 3 The push-off structure 63 includes a push-off plate 631 slidably disposed within the mounting housing 1 and located at the opening of the second accommodating chamber 3, and a push-off drive unit 632 disposed within the mounting housing 1 for driving the push-off plate 631 to reciprocate. The push-off plate 631 is located within a clearance groove on the movable transport member 61, and under the action of the push-off drive unit 632, the push-off plate 631 reciprocates in a direction perpendicular to the axis of the telescopic transport member 4, allowing the sampling module 13 to easily enter the second accommodating chamber 3 from the movable transport member 61, making storage of the sampling module 13 more convenient and quick.

[0038] In this embodiment, two guide rod push plates 631 are also provided on the inner wall of the mounting housing 1, capable of sliding along the length of the guide rods. The push drive unit 632 includes a rotating screw disposed parallel to the guide rods and a motor for driving the rotating screw. The rotating screw is disposed parallel to the multiple guide rods, and the motor is electrically connected to a controller, which controls the start, stop, and rotation of the motor. The motor is preferably a servo motor or a stepper motor, though a reduction motor may also be used.

[0039] As a specific embodiment of the smoke dust automatic sampling quality control device provided by the present invention, please refer to Figure 4 and Figure 5 ,and Figure 6 , a pushing mechanism 7 for pushing the sampling module 13 toward the outlet of the first accommodating chamber 2 is further provided in the first accommodating chamber 2, and a blocking mechanism 8 for blocking the sampling module 13 is further provided at the outlet of the first accommodating chamber 2. The setting of the pushing mechanism 7 can push multiple sampling modules 13 toward the mouth of the first accommodating chamber 2, and conveniently push the sampling modules 13 from the first accommodating chamber 2 to the movable transport member 61 of the mounting shell 1. The setting of the blocking mechanism 8 can block the sampling modules 13, and control the number of sampling modules 13 entering the interior of the mounting shell 1 from the first accommodating chamber 2 through the opening and closing of the blocking mechanism 8, ensuring that only one sampling module 13 enters the mounting shell 1 at a time, making the automatic sampling device more automated and easier to use.

[0040] As a specific embodiment of the smoke dust automatic sampling quality control device provided by the present invention, please refer to Figure 4 and Figure 5 The pushing mechanism 7 includes a pushing slider 71 slidably arranged at the bottom of the first accommodating chamber 2, a pushing elastic member 72 arranged in the first accommodating chamber 2 for pushing the pushing slider 71, and a movable member 73 arranged on the pushing slider 71. When the sampling module 13 is installed, the top of the movable member 73 can be tilted toward the blocking mechanism 8, and finally the movable member 73 is flattened as a whole and lower than the bottom surface of the first accommodating chamber 2, so that the sampling module 13 can pass through. Then, the sampling module 13 is blocked by the blocking mechanism 8, and the movable member 73 can be automatically lifted up under the action of the torsion spring, so that the movable member 73 is clamped on the side of the sampling module 13, and the sampling module 13 is pushed toward the mouth of the first accommodating chamber 2 under the action of the pushing elastic member 72.

[0041] In this embodiment, a sliding groove for accommodating the push slider 71 is further provided at the bottom of the bottom of the first accommodating chamber 2. The sliding groove is recessed at the bottom of the first accommodating chamber 2, and the pushing elastic member 72 is also provided in the sliding groove. A pulling handle for pulling the push slider 71 is further provided on the side of the push slider 71. A long groove for extending the pulling handle to the outside of the sliding groove is further provided on the side wall of the sliding groove. A locking unit 74 for fixing the position of the pulling handle is further provided on the outside of the shell of the first accommodating chamber 2. When the sampling module 13 is installed, the push slider 71 can be pulled to the position farthest from the outlet by pulling the handle, and then fixed by the locking unit 74. The locking unit 74 is released after the installation is completed.

[0042] In order to reduce the manufacturing cost, the locking unit 74 is usually a locking pin, and the pulling handle is in the shape of a plate. The pulling handle can be blocked by the visible pin, making it more convenient to fix the pulling handle.

[0043] In this embodiment, the movable part 73 can be a stop block slidably set on the pushing slider 71, and an elastic part is also provided between the stop block and the pushing slider 71. The elastic part can push the stop block in the direction away from the pushing slider 71, so that the stop block protrudes from the sliding groove setting, and the stop block can be pressed down so that the top of the stop block is lower than the bottom surface of the first accommodating chamber 2, so that the sampling module 13 can pass through. After the sampling module 13 passes through the stop block, the stop block is automatically lifted under the action of the torsion spring, and the stop block is clamped on the side of the sampling module 13, and pushes the pushing slider 71 and the stop block by pushing the elastic part 72. The stop block pushes the sampling module 13 toward the mouth of the first accommodating chamber 2, making it more convenient and reliable for the sampling module 13 to enter the installation shell 1.

[0044] As a specific embodiment of the smoke dust automatic sampling quality control device provided by the present invention, please refer to Figure 4 and Figure 5The side of the movable member 73 is hingedly mounted on the push slider 71. A compressive elastic member is provided at the connection between the movable member 73 and the push slider 71 for driving the movable member 73 to rotate toward the sampling module 13. The push slider 71 is also provided with a receiving groove for accommodating the movable member 73. The movable member 73 is in the shape of a plate. This mounting method of the movable member 73 makes it easier to turn over.

[0045] As a specific embodiment of the smoke dust automatic sampling quality control device provided by the present invention, please refer to Figure 6 The blocking mechanism 8 includes a movable baffle 81 movably arranged at the mouth of the first accommodating chamber 2 for blocking the sampling module 13, and a blocking drive unit 82 arranged at the mouth of the first accommodating chamber 2 for driving the movable baffle 81 to move. A second mounting plate 16 for mounting the blocking drive unit 82 is provided in the mounting shell 1. The second mounting plate 16 is also provided with a clearance groove for the movable baffle 81 to pass through. The second mounting plate 16 is located above the first accommodating chamber 2. The blocking drive unit 82 can drive the movable baffle 81 to block the mouth of the first accommodating chamber 2 or to make way for the sampling module 13 from the mouth of the first accommodating chamber 2 to pass through, ensuring that only one sampling module 13 enters the mounting shell 1 at a time, thereby making the automatic sampling device more automated.

[0046] In this embodiment, the blocking drive unit 82 includes a rotating screw disposed within the mounting housing 1 and a motor for driving the rotating screw. The motor is electrically connected to a controller, which controls the start, stop, and rotation of the motor. A servo motor or a stepper motor is generally preferred, but a reduction motor may also be used, depending on practical considerations and cost.

[0047] As a specific embodiment of the smoke dust automatic sampling quality control device provided by the present invention, please refer to Figure 1 and Figure 7 The telescopic transport member 4 is rod-shaped, and the plug-in unit 5 is provided at the end of the telescopic transport member 4. A reciprocating mechanism 43 for driving the telescopic transport member 4 to reciprocate along the axial direction is also provided in the mounting housing 1. Driven by the reciprocating mechanism 43, the telescopic transport member 4 reciprocates along its own axial direction, removing the sampling module 13 from the movable transport member 61 and sending it to the inside of the chimney or flue for sampling. After sampling is completed, the sampling module 13 is returned to the movable transport member 61. The provision of the reciprocating mechanism 43 makes the telescopic transport member 4 more automated and more convenient and quick to slide.

[0048] In this embodiment, the telescopic transport member 4 is in the shape of a cylinder with a hollow interior. The hollow interior of the telescopic transport member 4 reduces the overall weight of the telescopic transport member 4, and at the same time allows the circuit and air path connected to the plug-in unit 5 to pass through. The circuit and air path are connected to the air pump and the control unit of the mounting shell 1 through a drag chain arranged on the side of the telescopic transport member 4, preventing the circuit and air path from being entangled when the telescopic transport member 4 moves.

[0049] The reciprocating mechanism 43 includes a pulley assembly 431 disposed within the mounting housing 1 and extending along the length of the telescopic transport member 4, and a reciprocating power unit 432 disposed within the mounting housing 1 for driving the pulley assembly 431. A connecting unit is also disposed between the push-pull block 42 and the transmission belt of the pulley assembly 431, connecting the push-pull block 42 to the transmission belt. The pulley assembly 431 includes a first rotating wheel and a second rotating wheel, each of which rotates within the mounting housing 1, and a transmission belt wound around the first and second rotating wheels. The reciprocating power unit 432 is also disposed within the mounting housing 1 to drive the first or second rotating wheel. The use of the pulley assembly 431 to drive the reciprocating mechanism 43 increases the travel range of the telescopic transport member 4 and also ensures smoother movement of the telescopic transport member 4.

[0050] In this embodiment, the reciprocating mechanism 43 may also use a cylinder or an electric push rod to drive the telescopic transport member 4, or may use other linear drives, so that the structure of the reciprocating mechanism 43 is simpler.

[0051] In this embodiment, the connecting unit is a connecting piece provided between the push-pull block 42 and the conveyor belt. One end of the connecting piece is clamped and fixed on the conveyor belt, and the other end is fixed to the push-pull block 42 by screws.

[0052] As a specific embodiment of the smoke dust automatic sampling quality control device provided by the present invention, please refer to Figure 1 and Figure 7A support sleeve 41 for installing the telescopic transport member 4 is provided in the mounting shell 1. A push-pull block 42 for connecting the telescopic transport member 4 to the movable part of the reciprocating mechanism 43 is also provided at the end of the telescopic transport member 4. A rotating mechanism 44 for driving the telescopic transport member 4 to rotate around the axis is also provided in the mounting shell 1. The sliding is arranged in the support sleeve 41, and the push-pull block 42 is clamped on the end of the telescopic transport member 4 and is rotatably connected to the telescopic transport member 4. The telescopic transport member 4 adopts this mounting structure so that the telescopic transport member 4 can slide along the axial direction and can also rotate around the axial direction under the drive of the rotating mechanism 44. The setting of the rotating mechanism 44 can conveniently rotate the telescopic transport member 4. The angle of the air inlet pipe of the sampling head on the sampling module 13 installed at the end of the telescopic transport member 4 can be conveniently adjusted according to the airflow direction in the flue or chimney, making the collection of smoke and dust more flexible and convenient. Before collecting smoke and dust from a flue or chimney for the first time, the direction of the airflow can be measured. When the housing 1 is installed, the angle at which the telescopic transport member 4 rotates from the zero position to the most suitable position can be determined. Then, each time a measurement is performed, it is only necessary to control the telescopic transport member 4 to rotate to a fixed angle through the rotating mechanism 44, thereby making the measurement of the sampling device more accurate.

[0053] In this embodiment, the rotating mechanism 44 includes a rotating wheel 441 rotatably arranged at the end of the support sleeve 41 and coaxially arranged with the telescopic transport member 4, and a rotating power unit 442 for driving the rotating wheel 441 to rotate. The rotating wheel 441 is mounted on the outside of the telescopic transport member 4, and a driving protrusion is provided on the inner hole wall of the rotating wheel 441. A sliding long groove is provided on the circumferential surface of the telescopic transport member 4, which is arranged along the length direction of the telescopic transport member 4 and is adapted to the driving protrusion. The setting of the driving protrusion and the sliding long groove enables the telescopic transport member 4 to slide through the rotating wheel 441 while also rotating with the rotating wheel 441.

[0054] As a specific embodiment of the smoke dust automatic sampling quality control device provided by the present invention, please refer to Figure 2 and Figure 8 The side wall of the mounting housing 1 is further provided with a detection hole 11 for the passage of the telescopic transport member 4, and a sealing mechanism 9 for sealing the detection hole 11 is further provided in the mounting housing 1. The sealing mechanism 9 can block the detection hole 11 through the sealing mechanism 9 when the smoke automatic sampling quality control device is not sampling, thereby preventing smoke from the chimney or flue from entering the interior of the mounting housing 1.

[0055] As a specific embodiment of the smoke dust automatic sampling quality control device provided by the present invention, please refer to Figure 8The sealing mechanism 9 includes a first sealing plate 91 slidably disposed within the mounting housing 1 and a sealing drive unit 93 for driving the first sealing plate 91 to slide. Furthermore, to facilitate faster closing of the detection hole 11, a second sealing plate 92 is provided on the opposite side of the first sealing plate 91. The second sealing plate 92 slides relative to the first sealing plate 91 and is also driven by the sealing drive unit 93. When the automatic sampling device is not performing measurements, the two sealing drive units 93 drive the first sealing plate 91 and the second sealing plate 92 to move relative to each other, thereby sealing the detection hole 11.

[0056] In this embodiment, the first sealing plate 91 and the second sealing plate 92 are both provided with a makeshift groove matching the size and shape of the telescopic transport member 4 on the side close to the telescopic transport member 4. In this way, when the telescopic transport member 4 pushes the sampling module 13 out of the installation shell 1 for sampling, the first sealing plate 91 and the second sealing plate 92 can be placed against the telescopic transport member 4, and the detection hole 11 can still be sealed.

[0057] As a specific embodiment of the smoke dust automatic sampling quality control device provided by the present invention, please refer to Figure 8 The automatic smoke sampling quality control device also includes a cap removal clamp 12 disposed on the side of the first sealing plate 91, which is used to remove the sealing cap of the sampling head on the sampling module 13 from the sampling head and reinstall it on the sampling head after the test is completed. The cap removal clamp 12 is mounted on the first sealing plate 91, and the first sealing plate 91 can slide up and down under the drive of the sealing drive unit 93. The cap removal clamp 12 is moved to an appropriate height under the drive of the first sealing plate 91. When the telescopic transport member 4 transports the sampling module 13 to the cap removal clamp 12, the cap removal clamp 12 clamps the sealing cap and then removes the sealing cap from the sampling head under the drive of the first sealing plate 91. Similarly, the sealing cap can also be installed on the sampling head. The provision of the cap removal clamp 12 allows the sealing cap of the standard sampling head of the sampling module 13 to be removed before the telescopic transport member 4 transports the sampling module 13 to the chimney or flue, and the sealing cap is reinstalled at the entrance of the sampling head after sampling is completed, making sampling by the automatic smoke sampling quality control device simpler and more convenient, and also making smoke sampling more accurate.

[0058] As a specific embodiment of the smoke dust automatic sampling quality control device provided by the present invention, please refer to Figure 8Since there are multiple sampling modules 13 in the device, in order to identify the identity information of the sampling module 13 that is entering the installation shell 1 and is being docked and used, and to ensure the correct position of the sampling module 13 on the movable transport part 61, an identification mechanism 14 for detecting the identity information of the sampling module 13 is also provided inside the installation shell 1, and a corresponding label is also affixed to the surface of the sampling module 13. The setting of the identification mechanism 14 can identify and confirm the identification information on the sampling module 13 to prevent the reuse of the wrong or used sampling module 13, and at the same time ensure that the sampling module 13 is in the correct position. The identification mechanism 14 includes an identification unit for the label on the equipment sampling module 13 and a driving cylinder for pushing the identification unit to move. The identification unit can choose a card reader that reads the electronic tag, or it can be a barcode scanner that can read barcodes or QR codes. The identification unit is electrically connected to the controller to record the usage status of the sampling module 13.

[0059] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
