[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example: Reference Figure 1-Figure 5 The tower gas sampling device shown includes a tower body 1 and a sampling barrel 20. The gas inlet end of the sampling barrel 20 is provided with a valve. An air inlet box 4 is provided in the tower body 1 via a lifting mechanism. The lifting mechanism is used to drive the air inlet box 4 to achieve a lifting function. The sampling barrel 20 is provided outside the tower body 1 via a squeezing mechanism. The squeezing mechanism is used to fix the sampling barrel 20.

[0026] The lifting mechanism includes a lower plate 2 and an upper plate 3, and the lower plate 2 and the upper plate 3 are both arranged on the inner wall of the circumference of the tower body 1. Two limit rods 5 are fixedly installed on the opposite sides of the lower plate 2 and the upper plate 3. The air intake box 4 is slidably installed on the two limit rods 5. The top of the air intake box 4 is provided with a control component, the side of the air intake box 4 is provided with an air intake pipe 10, and a filter component is provided in the air intake box 4. The lower plate 2 and the tower body 1 are jointly provided with an L-shaped pointed nozzle pipe 12, and the top of the lower plate 2 is provided with an air pump 13. The air inlet end of the air pump 13 is provided with a telescopic tube 14. The top of the telescopic tube 14 is connected to the air intake box 4, and the output end of the air pump 13 is connected to the L-shaped pointed nozzle pipe 12;

[0027] The extrusion mechanism includes a fixed plate 15, which is fixedly installed on the outer wall of the tower body 1. A U-shaped extrusion plate 19 is slidably installed on the top of the fixed plate 15 through a sliding assembly. The sampling tube 20 is adapted to the L-shaped pointed nozzle tube 12 and the U-shaped extrusion plate 19. A piston 21 is slidably installed in the sampling tube 20. A pull rod 22 is provided on the side of the piston 21. The other end of the pull rod 22 extends to the outside of the sampling tube 20 and is provided with an operating panel.

[0028] With the above structure, when in use, first open the valve at the air inlet end of the sampling tube 20, and insert the pointed end of the L-shaped pointed nozzle tube 12, and then drive the U-shaped extrusion plate 19 to move horizontally through the sliding component to squeeze and fix the sampling tube 20. The fixing operation is simple through extrusion, which facilitates the installation, disassembly and replacement of the sampling tube 20; then turn on the air pump 13, and extract air through the air inlet pipe 10 and the air inlet box 4, and input the gas into the sampling tube 20 through the telescopic tube 14 and the L-shaped pointed nozzle tube 12. The piston 21 moves horizontally through the action of air pressure until the sampling tube 20 is filled with gas. When the sampling height needs to be adjusted, the air inlet box 4 can be driven by the control component to realize the lifting function, thereby realizing sampling and detection of gases at different heights, which is highly practical.

[0029] like Figure 3 As shown, the control component includes a winding roller 7, a rectangular hole is opened on the top of the upper plate 3, and a winding shaft is installed on the relative inner walls of the rectangular hole for common rotation. The winding roller 7 is fixedly sleeved on the winding shaft, and a motor slot is opened on the side inner wall of the rectangular hole. A winding motor 8 is fixedly installed in the motor slot, and the output shaft of the winding motor 8 is fixedly connected to one end of the winding shaft. A wire rope 9 is wound around the winding roller 7, and the other end of the wire rope 9 is fixedly connected to the top of the air intake box 4. This arrangement can realize the winding and releasing function of the wire rope 9 through the rotation of the winding roller 7, and the height adjustment function of the air intake box 4 is realized through the winding and releasing of the wire rope 9 and the cooperation of the gravity of the air intake box 4.

[0030] Specifically, when the winding motor 8 drives the winding roller 7 to rotate forward, the winding roller 7 reels the wire rope 9. At this time, the wire rope 9 pulls the air intake box 4 upward to achieve upward adjustment. When the winding motor 8 drives the winding roller 7 to rotate reversely, gravity causes the air intake box 4 to move downward to achieve downward adjustment.

[0031] like Figure 2 As shown, the two limit rods 5 are each provided with a return spring 6, the top ends of the two return springs 6 are fixedly mounted on the bottom of the air intake box 4, and the bottom ends of the two return springs 6 are fixedly mounted on the top of the lower plate 2. This arrangement can drive the air intake box 4 to move downward rapidly through its elastic action when the winding roller 7 reverses.

[0032] Specifically, when the air intake box 4 moves upward, the return spring 6 is stretched. When the winding roller 7 reverses, the air intake box 4 can be driven to move downward quickly through the action of gravity and the elastic action of the return spring 6, thereby realizing the downward adjustment function.

[0033] like Figure 3 As shown, the filter assembly includes a filter plate 11. A mounting hole is provided on the top of the air inlet box 4. The filter plate 11 is slidably arranged in the mounting hole. This arrangement allows the gas to be filtered through the filter plate 11 to prevent foreign matter from entering.

[0034] Specifically, by disposing the filter plate 11 , larger foreign matter can be filtered to prevent clogging of the L-shaped pointed nozzle tube 12 and affecting the sampling operation.

[0035] like Figure 5As shown, the sliding assembly includes a screw 17, a sliding hole is opened at the top of the fixed plate 15, one end of the screw 17 is rotatably mounted on the side inner wall of the sliding hole, and the other end of the screw 17 extends outside the sliding hole and is fixedly mounted with a handwheel 18, and a slider 16 is threadedly mounted on the screw 17, and the top of the slider 16 is fixedly connected to the bottom of the U-shaped extrusion plate 19. This arrangement can drive the slider 16 to move horizontally through the action of the thread, thereby realizing the extrusion and fixation of the end of the sampling tube 20 through the U-shaped extrusion plate 19.

[0036] Specifically, when the sampling tube 20 needs to be fixed, the screw 17 is driven to rotate by rotating the handwheel 18, thereby driving the slider 16 and the U-shaped extrusion plate 19 to move horizontally under the action of the thread, thereby squeezing and fixing one end of the sampling tube 20. The installation operation is simple and convenient, and the work efficiency is improved.

[0037] like Figure 5 As shown, a protection pad is provided on the side of the U-shaped extrusion plate 19. Such an arrangement can protect the sampling tube 20 through the protection pad when it is extruded and fixed.

[0038] Specifically, when the U-shaped extrusion plate 19 squeezes and fixes the sampling tube 20, the provision of the protection pad can play a protective role and prevent the sampling tube 20 from being damaged during the squeezing.

[0039] like Figure 5 As shown, a sensing groove is provided on the side of the piston 21, and a sensor 23 is provided in the sensing groove. The sensor 23 is electrically connected to the vacuum pump 13. Such a setting enables the sensor 23 to play a sensing role when the piston 21 moves to the inner wall of one end of the sampling tube 20.

[0040] Specifically, when the piston 21 moves to the inner wall of one end of the sampling cylinder 20, the sensor 23 senses that the sampling cylinder 20 is full of gas, thereby sending an electrical signal to the air pump 13 to stop the air intake operation, with a high degree of automation.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
