[0026] 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.

[0027] Please also refer to Figure 1 and Figure 2 The automatic smoke sampling quality control device provided by the present invention will now be described. The automatic smoke sampling quality control device includes a mounting housing 1, a switching mechanism 2 disposed within the mounting housing 1 for mounting and accommodating a plurality of sampling modules 9, a telescopic transport member 3 disposed within the mounting housing 1 for pushing the sampling modules 9 out or retracting them into the mounting housing 1, the telescopic transport member 3 further being provided with a plug-in unit 4 for plugging and fixing the sampling modules 9, the plug-in unit 4 connecting the sampling modules 9 to an external exhaust pipeline and an external circuit, and a moving mechanism 5 disposed within the mounting housing 1 for transporting the sampling modules 9 between the telescopic transport member 3 and the switching mechanism 2.

[0028] Compared with the prior art, the automatic smoke sampling quality control device provided in this embodiment is different from the prior art in that the mounting shell 1 is fixed on the side wall flange of the flue or chimney, and the mounting shell 1 is connected to the inside of the flue or chimney. A switching mechanism 2 is provided inside the mounting shell 1, and multiple sampling modules 9 are placed on the switching mechanism 2. Then the moving mechanism 5 transports the sampling module 9 from the switching mechanism 2 to the telescopic transport member 3, and extends the sampling module 9 to the outside of the mounting shell 1 for sampling through the movement of the telescopic transport member 3. The sampling module 9 is fixed to the end of the telescopic transport member 3 through the plug-in unit 4 and is connected to the external exhaust pipe and circuit. After the sampling is completed, the sampling module 9 is removed from the telescopic transport member 3 by the moving mechanism 5 and replaced on the mounting position of the switching mechanism 2. Then, the new sampling module 9 is moved to the designated position through the movement of the switching mechanism 2, so that the moving mechanism 5 can remove the new sampling module and then install it on the telescopic transport member 3 for the next sampling. The automatic smoke sampling quality control device of the present invention can place multiple sampling modules 9 in the installation shell 1 through the setting of the switching mechanism 2, and realize automatic replacement of the sampling modules 9 through the switching action of the switching mechanism 2, so that the automatic smoke sampling quality control device has a higher degree of automation and also improves the working efficiency and sampling accuracy of smoke collection.

[0029] In this example, see Figure 9 The sampling module 9 is an integral unit consisting of a protective shell and a standard sampling head arranged outside the standard sampling head 98, including a housing 91, a mounting member 92 arranged inside the housing 91 for mounting the sampling head, and an exhaust cavity 93 whose mouth is connected to the gas outlet of the sampling head 98. The mounting member 92 presses and fixes the sampling head 98 to the mouth of the exhaust cavity 93. The exhaust cavity 93 is also provided with an exhaust port 95 for connecting to an exhaust device for discharging the gas in the exhaust cavity. A heating unit 94 for heating the filter membrane on the sampling head is also provided in the housing. The heating unit 94 includes a plurality of heating elements arranged around the sampling head, and a connecting terminal 96 arranged in the housing and connected to the heating element circuit. A connecting pipe is also provided on the plug-in unit 4, and a positioning pin is also provided on the plug-in unit 4 that matches the position and size of the positioning hole on the housing of the sampling module 9.

[0030] As a specific embodiment of the smoke dust automatic sampling quality control device provided by the present invention, please refer to Figure 3The switching mechanism 2 includes a switching turntable 21 rotatably disposed within the housing, and a driving mechanism 22 for driving the switching turntable 21 to rotate. The switching turntable 21 is provided with a plurality of mounting structures 23 for mounting the sampling modules 9. The plurality of mounting structures 23 are evenly arranged on the side of the switching turntable 21 along a circle concentric with the switching turntable 21. Before measurement, the plurality of sampling modules 9 are mounted on the mounting structures 23 on the switching turntable 21. The telescopic transport member 3 moves to a position close to the detection hole 11. The moving mechanism 5 removes the sampling module 9 from the mounting structure 23 of the switching mechanism 2 and places it on the telescopic transport member 3. The plug-in unit 4 at the end of the telescopic transport member 3 is fixedly engaged with the end of the sampling module 9. The telescopic transport member 3 then pushes the sampling module 9 out of the housing 1 for sampling. After sampling is completed, the end of the telescopic transport member 3 is retracted into the housing 1. The moving mechanism 5 removes the sampling module 9 from the telescopic transport member 3 and re-mounts the sampling module 9 in the mounting structure 23. Finally, the driving mechanism 22 drives the switching turntable 21 to rotate a certain angle (the angle size matches the number of the mounting structures 23), and rotates the new sampling module 9 to the specified position, completing the automatic replacement and installation of the sampling module 9, making the replacement and removal of the sampling module 9 more convenient and quick, and making the switching mechanism 2 more convenient to use.

[0031] In this embodiment, multiple auxiliary wheels 24 are rotatably mounted within the mounting housing 1. These auxiliary wheels 24 are distributed along the circumference of the switching disc 21 and are provided with grooves around the circumference of the auxiliary wheels 24 for receiving the edge of the disc body of the switching disc 21. Multiple rotating shafts for mounting the auxiliary wheels 24 are provided within the mounting housing 1. These shafts are parallel to the telescopic transport member 3, ensuring a more secure mounting of the auxiliary wheels 24. The multiple auxiliary wheels 24 securely secure the switching disc 21, enabling the switching disc 21 to be rotatably mounted within the mounting housing 1. This mounting structure for the switching disc 21 ensures a more stable and reliable installation and rotation, and allows the telescopic transport member 3 to easily pass through the center of the switching disc 21. Of course, the switching disc 21 can also be mounted using other mounting methods, such as a rotatable connection to the side wall of the mounting housing 1 via an internal hollow sleeve. In order to cooperate with the installation method of the switching turntable 21, the driving mechanism 22 includes a driving wheel that is rotatably arranged on the side wall of the mounting shell 1 and is tightly attached to the circumference of the switching turntable 21, and a driving mechanism 22 for driving the driving wheel to rotate. In order to ensure the accuracy and response speed of the rotation of the switching turntable 21, the driving mechanism 22 usually uses a servo motor or a stepper motor, but of course other motors can also be used.

[0032] As a specific embodiment of the smoke automatic sampling quality control device provided by the present invention, please refer to Figure 3. The mounting structure 23 includes two clamping plates 231 spaced apart on the switching turntable 21. The two clamping plates 231 form a housing for accommodating the sampling module 9. Positioning protrusions 232 are also provided on the side walls of the housing. There are multiple mounting structures 23. The sampling module 9 can be clamped and fixed by the clamping plates 231. Positioning protrusions 232 are also provided on the side walls of the housing. The positioning protrusions 232 match the positioning grooves on the sides of the sampling module 9, making the installation position of the sampling module 9 more accurate. In addition, the fixing method of clamping and fixing the sampling module 9 with two clamping plates 231 makes the three sides of the housing cavity open structures, which facilitates the removal of the sampling module 9 from the housing cavity or the installation of the sampling module 9 into the housing cavity.

[0033] In this embodiment, an elastic push pin 233 for positioning the sampling module 9 is also provided on the mounting structure 23. The elastic end of the elastic push pin 233 is located inside the accommodating cavity and corresponds to the position of the positioning hole on the end of the sampling module 9. The elastic push pin 233 can position the sampling module 9 in the radial direction of the switching disk after the sampling module 9 is installed between the two clamping plates 231, so that the installation position of the sampling module 9 in the mounting structure 23 is more accurately fixed.

[0034] As a specific embodiment of the smoke automatic sampling quality control device provided by the present invention, please refer to FIG. Figure 3 , multiple mounting structures 23 are evenly distributed around the axis of the telescopic transport member 3, and a moving mechanism 5 for transporting the sampling module 9 between the telescopic transport member 3 and the mounting structure 23 is also provided in the mounting shell 1. At this time, a clearance hole for the telescopic transport member 3 to pass through is provided in the center of the switching turntable 21. The telescopic transport member 3 and the switching turntable 21 are coaxially arranged, and the clamping plates 231 that constitute the mounting structure 23 are all arranged along the radial direction of the switching turntable 21. The sides of the accommodating cavity close to the telescopic transport member 3 and away from the telescopic transport member 3 are both open structures. At this time, an accommodating groove 31 for accommodating the installation of the sampling module 9 is also provided on the telescopic transport member 3, so that the installation and fixation of the sampling module 9 is more firmly secured. With this arrangement, the mounting structure 23 can conveniently push the sampling module 9 from the opening structure into the accommodating groove 31 on the telescopic transport member 3 through the moving mechanism 5, making the movement of the sampling module 9 more convenient.

[0035] As a specific embodiment of the smoke automatic sampling quality control device provided by the present invention, please refer to FIG. Figure 7The moving mechanism 5 includes a pushing unit 51 provided on the mounting housing 1, a pushing arm 52 provided at the movable end of the pushing unit 51, and a movable clamping unit 53 provided at the end of the pushing arm 52 for clamping the sampling module 9. The moving mechanism 5 adopts this structure to conveniently remove the sampling module 9 from the mounting structure 23 on the switching disk by the movable clamping unit 53, and to push the sampling module 9 into the receiving groove 31 on the telescopic transport member 3 by the pushing unit 51. The movable clamping unit 53 then releases the sampling module 9 and returns to its original position, completing the movement and loading of the sampling module 9. After smoke sampling, the sampling module 9 is removed and replaced in the mounting structure 23 of the switching turntable 21 by the reverse action.

[0036] In this embodiment, the movable clamping unit 53 includes a fixed clamping piece arranged at the end of the pushing arm 52, a clamping cylinder arranged on the pushing arm 52, and a movable clamping piece arranged at the movable end of the clamping cylinder. When the sampling module 9 needs to be moved, the fixed clamping piece and the movable clamping piece respectively abut against the two ends of the sampling module 9. The clamping unit adopts this structure to conveniently clamp and move the sampling module 9.

[0037] As a specific embodiment of the smoke dust automatic sampling quality control device provided by the present invention, please refer to Figure 1 、 Figure 4 and Figure 5 The telescopic transport member 3 is rod-shaped, with a plug-in unit 4 positioned at the end of the telescopic transport member 3. A push-pull mechanism 32 is also located within the mounting housing 1, driving the telescopic transport member 3 to reciprocate along its axis. The push-pull mechanism 32 includes a drive belt assembly 321 disposed within the mounting housing 1 and extending along the length of the telescopic transport member 3, and a power unit 322 mounted on the inner wall of the mounting housing 1 to drive the drive belt assembly 321. A connecting unit is also provided between the push-pull bracket 33 and the drive belt of the drive belt assembly 321, connecting the push-pull bracket 33 to the drive belt. The drive belt assembly 321 includes a first rotating wheel and a second rotating wheel mounted on the side wall of the mounting housing 1, respectively, and a drive belt looped around the first and second rotating wheels. The mounting housing 1 also includes a power unit 322 for driving the first and second rotating wheels. The use of the drive belt assembly 321 to drive the push-pull mechanism 32 increases the travel range of the telescopic transport member 3 and ensures smoother movement of the telescopic transport member 3.

[0038] In this embodiment, the push-pull mechanism 32 may also use a cylinder or an electric push rod to drive the telescopic transport member 3, or other linear drives to make the structure of the push-pull mechanism 32 simpler.

[0039] In this embodiment, there are two or more drive belt assemblies 321, each disposed on either side of the telescopic transport member 3 and extending axially therefrom. Both sides of the push-pull bracket 33 are connected to the drive belts of the drive belt assemblies 321 via connecting units. Movement of the drive belts drives the push-pull bracket 33 along the sliding rod. Only one of the two drive belt assemblies 321 is equipped with a power unit 322. A connecting belt assembly is provided between the two drive belt assemblies 321 to ensure synchronized operation of the two drive belt assemblies 321, preventing asynchronous movement of the two sides of the push-pull bracket 33. This ensures more synchronized movement of the two sides of the push-pull bracket 33 and smoother movement of the push-pull bracket 33 and the telescopic transport member 3.

[0040] In this embodiment, the connecting unit is a connecting piece provided between the push-pull bracket 33 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 bracket 33 by screws.

[0041] As a specific embodiment of the smoke automatic sampling quality control device provided by the present invention, please refer to FIG. Figure 4 and Figure 5 , a rotating mechanism 34 for driving the telescopic transport member 3 to rotate around the axis is also provided in the mounting shell 1. The setting of the rotating mechanism 34 can conveniently rotate the telescopic transport member 3, and can conveniently adjust the angle of the air inlet pipe of the sampling head on the sampling module 9 installed at the end of the telescopic transport member 3 according to the direction of the airflow in the flue or chimney, making the collection of smoke and dust more flexible and convenient. Before collecting smoke and dust from the flue or chimney for the first time, the direction of the airflow can be measured, and the angle of the telescopic transport member 3 from the zero position to the most suitable position can be determined when the mounting shell 1 is installed. Then, in each measurement, it is only necessary to control the telescopic transport member 3 to rotate to a fixed angle through the rotating mechanism 34.

[0042] In this embodiment, the telescopic transport member 3 is rotatably provided with a push-pull bracket 33 for connecting the telescopic transport member 3 to the push-pull mechanism 32. The push-pull bracket 33 is also slidably provided within the mounting housing 1 to drive the telescopic transport member 3 to slide axially. A rotation mechanism 34 is disposed between the push-pull bracket 33 and the ends of the telescopic transport member 3. The rotation mechanism 34 is disposed between the push-pull bracket 33 and the telescopic transport member 3. The push-pull mechanism 32 propels the telescopic transport member 3, the push-pull bracket 33, and the rotation mechanism 34 to slide together. Parallel sliding rods are also provided within the mounting housing 1. The push-pull bracket 33 is slidably connected to the sliding rods at both ends. Driven by the push-pull mechanism 32, the push-pull bracket 33 slides axially along the telescopic transport member 3, with the telescopic transport member 3 and the rotation mechanism 34 simultaneously sliding along with the push-pull bracket 33. The arrangement of the push-pull bracket 33 allows the push-pull mechanism 32 to push the push-pull bracket 33 while the rotation mechanism 34 also drives the telescopic transport member 3 to rotate. This makes the telescopic transport member 3 more flexible and convenient to use and enhances the accuracy of smoke sampling results.

[0043] In this embodiment, the preferred rotating mechanism 34 is generally a servo motor, but can also be a stepper motor or other types of motors. The body of the rotating mechanism 34 is fixedly mounted on the push-pull bracket 33 and can slide with the push-pull bracket 33. The rotating end of the rotating mechanism 34 is connected to the end of the telescopic transport member 3. The push-pull bracket 33 is connected to the end of the telescopic transport member 3 through the rotating mechanism 34, making the installation of the rotating mechanism 34 more convenient.

[0044] In this embodiment, an additional support sleeve for supporting the telescopic transport member 3 is provided on the inner wall of the mounting shell 1. The support sleeve is provided coaxially with the telescopic transport member 3, and the telescopic transport member 3 is slidably provided in the support sleeve. This makes the installation of the telescopic transport member 3 more stable. The telescopic transport member 3 is cylindrical with a hollow interior. The hollow interior of the telescopic transport member 3 reduces the overall weight of the telescopic transport member 3, and at the same time allows the circuit and air path connected to the plug-in unit 4 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 provided on the side of the telescopic transport member 3, preventing the circuit and air path from getting entangled when the telescopic transport member 3 moves, making the telescopic movement of the telescopic transport member 3 more convenient.

[0045] As a specific embodiment of the smoke automatic sampling quality control device provided by the present invention, please refer to FIG. Figure 6 and Figure 8The end of the telescopic transport member 3 is also provided with a receiving groove 31 for accommodating the sampling module 9. The side wall of the receiving groove 31 is provided with a clamping structure for clamping the sampling module 9. The plug-in unit 4 is also provided in the receiving groove 31. The provision of the receiving groove 31 and the clamping structure makes the installation and removal of the sampling module 9 more convenient and quick. The sampling module 9 is clamped and moved from the installation structure to the receiving groove 31 and connected to the plug-in unit 4 through the moving mechanism. At the same time, the plug-in unit 4 is also provided in the receiving groove 31, so that the sampling module 9 can be connected to the external circuit and the gas path at the same time as it is installed, making the installation of the sampling module 9 more secure and more convenient.

[0046] In this embodiment, the clamping structure is a positioning protrusion 232 provided on the side wall of the accommodating groove 31. Simultaneously, a clamping groove 97 is also provided on the outer wall of the sampling module 9 to cooperate with the positioning protrusion 232. The positioning protrusion 232 and the clamping groove 97 can be arranged to clamp and fix the sampling module 9 along the axial direction of the movable rod.

[0047] As a specific embodiment of the smoke automatic sampling quality control device provided by the present invention, please refer to FIG. Figure 8 The telescopic transport member 3 is also provided with a plug-in push-pull unit 35 for pushing the plug-in unit 4. The plug-in push-pull unit 35 is also disposed within the receiving groove 31, and the plug-in unit 4 is disposed at the movable end of the plug-in push-pull unit 35. The plug-in unit 4 is disposed at the movable end of the plug-in push-pull unit 35. A mounting bracket for mounting and fixing the plug-in push-pull unit 35 is also provided within the telescopic transport member 3. The positioning protrusions are also provided for removing the snap-on tabs provided on the inner wall of the mounting bracket, facilitating assembly of the telescopic transport member 3. The plug-in unit 4 is also provided with positioning pins for positioning the sampling module 9. After the sampling module 9 is fixed by the card-mounted structure, the plug-in unit 4 is pushed toward the sampling module 9 by the plug-in push-pull unit 35, so that the connecting pipe and the connecting terminal on the plug-in unit 4 are connected with the exhaust port and the connecting terminal on the sampling module 9, connecting the sampling module 9 with the external circuit and the external exhaust pipeline. When the sampling module 9 needs to be disassembled, the plug-in push-pull unit 35 pulls the plug-in unit 4 backward, so that the plug-in unit 4 can be quickly separated from the sampling module 9, making it convenient to remove the sampling module 9 from the accommodating groove 31.

[0048] In this embodiment, the end of the sampling module 9 is also provided with a positioning hole that cooperates with the positioning pin on the plug-in unit 4. The end of the positioning pin protrudes from the end face of the plug-in unit 4. This can ensure that the positioning pin is inserted into the positioning hole to position and adjust the position of the sampling module 9 before the plug-in unit 4 contacts the sampling module 9, making the installation of the sampling module 9 more precise, avoiding the misalignment of the exhaust port and the connection terminal on the sampling module 9 and the plug-in unit 4, and making the connection between the sampling module 9 and the external circuit and the exhaust pipeline more reliable.

[0049] As a specific embodiment of the smoke automatic sampling quality control device provided by the present invention, please refer to FIG. Figure 7 The automatic smoke sampling and quality control device also includes a cap-removing mechanism 7 disposed on the inner wall of the mounting housing 1 and used to remove and install the sealing cap of the sampling head on the sampling module 9. The cap-removing mechanism 7 can remove the sealing cap of the sampling head of the sampling module 9 before the telescopic transport member 3 transports the sampling module 9 into the chimney or flue, and re-install the sealing cap at the entrance of the sampling head after sampling is completed, thereby making the sampling of the automatic smoke sampling and quality control device more accurate.

[0050] As a specific embodiment of the smoke automatic sampling quality control device provided by the present invention, please refer to FIG. Figure 7 The cap-removing mechanism 7 includes a cap-removing driving unit 73 provided on the inner wall of the mounting housing 1, a cap-removing bracket 72 provided at the movable end of the cap-removing driving unit 73, and a cap-removing clamping unit 71 provided on the cap-removing bracket 72. The cap-removing mechanism 7 includes a cap-removing driving unit 73 provided on the inner wall of the mounting housing 1, a cap-removing bracket 72 provided at the movable end of the cap-removing driving unit 73, and a cap-removing clamping unit 71 provided on the cap-removing bracket 72. The cap-removing driving unit 73 drives the cap-removing bracket 72 and the cap-removing clamping unit 71 provided on the cap-removing bracket 72 to move. When the cap-removing clamping unit 71 moves to the sealing cap on the sampling head, the cap-removing clamping unit 71 tightens the sealing cap. Then, the cap-removing driving unit 73 drives the cap-removing bracket 72 and the cap-removing clamping unit 71 to return to their original positions, thereby removing the sealing cap from the mouth of the sampling head. After sampling is completed, the above-mentioned action is repeated to reinstall the sealing cap at the mouth of the sampling head.

[0051] As a specific embodiment of the smoke automatic sampling quality control device provided by the present invention, please refer to FIG. Figure 7 The mounting housing 1 is also provided with a detection hole 11 for the telescopic transport member 3 and the sampling module 9 to pass through. A sealing mechanism 6 is also provided within the mounting housing 1 for closing the detection hole 11 after sampling is completed. The sealing mechanism 6 can be used to block the detection hole 11 during the non-sampling period of the smoke automatic sampling quality control device, thereby preventing smoke from entering the mounting housing 1.

[0052] Furthermore, to ensure that detection hole 11 remains sealed when telescopic transport member 3 is pushed out of mounting housing 1, telescopic transport member 3 is cylindrical and slidable along its own axial direction within the mounting housing. The diameter of telescopic transport member 3 matches the diameter of detection hole 11, requiring the sampling module 9 to be smaller than the telescopic transport member 3 to facilitate the free passage of sampling hole 11. During sampling, the circumference of telescopic transport member 3 is tightly attached to the inner wall of detection hole 11, thereby sealing detection hole 11 and preventing smoke from entering mounting housing 1 through detection hole 11 during the sampling process.

[0053] As a specific embodiment of the smoke automatic sampling quality control device provided by the present invention, please refer to FIG. Figure 7 The sealing mechanism 6 includes a sealing drive unit 61 mounted on the inner wall of the mounting housing 1, and a sealing plate 62 disposed at the movable end of the sealing drive unit 61 and resting against the inner wall of the mounting housing 1 for sealing the detection hole 11. A sealing protrusion is also provided near the detection hole 11 to cooperate with the sealing plate 62. When the detection hole 11 needs to be opened, the sealing drive unit 61 pulls the sealing plate 62 to open the detection hole 11. When the detection hole 11 needs to be closed, the sealing drive unit 61 pushes the sealing plate 62 to close the detection hole 11, making the opening and closing of the detection hole 11 more convenient and quick.

[0054] As a specific embodiment of the automatic sampling quality control device for smoke and dust provided by the present invention, please refer to Figure 1. In order to ensure the accuracy of the rotation position of the switching turntable 21 and accurately identify and record the status information of the sampling module, an identification mechanism 8 for detecting the sampling module 9 is also provided inside the installation shell 1, and a corresponding label is also affixed to the surface of the sampling module 9. The setting of the identification mechanism 8 can ensure the accuracy of the rotation position of the switching turntable 21, and at the same time, it can also identify and confirm the label on the sampling module 9 to prevent the reuse of the wrong or used sampling module 9. The identification mechanism 8 includes an identification unit for the label on the equipment sampling module 9 and a driving cylinder for pushing the identification unit to move. The identification unit can choose a card reader for reading electronic tags, 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 9.

[0055] 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.
