Description

Technical Field

[0001] This utility model relates to the field of waste gas sampling technology, specifically to a waste gas sampling smoke gun holder. Background Technology

[0002] With social progress, the inspection of exhaust gas emissions is also being strengthened. Since exhaust gas mainly consists of gaseous components and trace amounts of harmful gases, the collection and detection of exhaust gas can be used to check the combustion of fuel and whether exhaust gas emissions meet the standards. Therefore, exhaust gas sampling and detection is crucial. Current exhaust gas detection mainly involves inserting a sampling nozzle into the flue to collect samples.

[0003] For example, Chinese Patent (CN212568121U) discloses a waste gas sampling gun holder, which includes a base, on which legs, a lifting ring, and a guide rod are installed. A support seat is fixedly installed on the surface of the base, and a sliding block is movably installed on the inner wall of the support seat. A left-right adjustment component is fixedly installed on the surface of the sliding block. The beneficial effect of this utility model is that by installing the up-down adjustment component and the left-right adjustment component on the base, the sampling gun can be fixed to the left-right adjustment component during use. The left-right adjustment component allows the sampling gun to be adjusted left and right, while the up-down adjustment component allows for up-down adjustment. Since neither the up-down nor the left-right adjustment components use fixing parts, it is more convenient to adjust the sampling gun, thereby greatly increasing work efficiency and ultimately achieving the goal of facilitating the adjustment of the sampling gun position.

[0004] The legs of the aforementioned device are welded to the base, which makes the bracket inconvenient to store. The bracket cannot be folded or disassembled, resulting in it occupying a large space and being very inconvenient to transport and store, especially in situations where the bracket needs to be moved frequently. This may require more storage space and additional transportation vehicles, which increases operating costs and labor intensity. The fixed leg design also makes it impossible for the bracket to be flexibly adjusted in different working environments, and it is impossible to flexibly change the angle or height according to the space conditions or measurement needs on site. To address the above problems, a waste gas sampling smoke gun bracket is proposed to solve the problem. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a waste gas sampling smoke gun bracket, which solves the problems of current brackets being inconvenient to store, not being foldable or disassembled, resulting in them occupying a large space and being very inconvenient to transport and store, especially in situations where the bracket needs to be moved frequently, which may require more storage space and additional transportation tools, increasing operating costs and labor intensity. The fixed leg design also makes it impossible for the bracket to be flexibly adjusted in different working environments, and it is impossible to flexibly change the angle or height according to the space conditions or measurement needs on site.

The top of the connecting rod is rotatably connected to the second rotating sleeve through a rotating shaft.

[0012] Preferably, the diameter of the fixing rod is larger than the diameter of the insertion hole.

[0013] Compared with the prior art, the advantages of this utility model are as follows: This utility model achieves height adjustment through the telescopic rod of the support assembly via the telescopic sleeve and locking nut, adapting to different flue height requirements and avoiding the safety hazards of manual climbing required by traditional fixed supports. The legs can be adjusted in opening angle via locking pins to adapt to uneven ground or narrow spaces, ensuring the stability of the support. The second threaded rod of the opening assembly drives the connecting rod to adjust the opening radius of the three sets of legs, providing a larger support area and preventing settlement. At the same time, rotating the handwheel can also quickly fold the support for rapid storage, allowing the exhaust gas sampling support to be easily folded and stored when not in use. It occupies little space, is easy to transport and store, reduces the cumbersome assembly process, and improves the efficiency of on-site operation. Attached Figure Description

[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0022] Reference Figure 1-5As shown, a waste gas sampling smoke gun bracket includes a fixed plate 1. Three sets of first rotating sleeves 2 are fixedly connected to the outside of the fixed plate 1. A bracket assembly 8 is rotatably connected below the three sets of first rotating sleeves 2. An opening assembly 9 is provided in the middle of the lower part of the fixed plate 1. At least three insertion holes 3 are provided through the upper surface of the fixed plate 1. A first threaded rod 4 is inserted into each of the three insertion holes 3. A second wing nut 10 for fixing is threaded to the bottom end of each of the three first threaded rods 4. A fixing rod 5 is fixedly connected above each of the three first threaded rods 4. A first semi-circular clamp 6 is fixedly connected to the top of each of the three fixing rods 5. A second semi-circular clamp 7 is rotatably connected above the first semi-circular clamp 6.

[0023] Furthermore, the support assembly 8 includes a telescopic sleeve 801, a rotating block 802 is fixedly connected above the telescopic sleeve 801, the rotating block 802 is rotatably connected to the inside of the first rotating sleeve 2 via a rotating shaft, and a telescopic rod 803 is slidably connected inside the telescopic sleeve 801.

[0024] Specifically, the telescopic sleeve 801 is threadedly connected to a locking nut 804 for fixing the telescopic rod 803, and a second rotating sleeve 805 is fixedly connected to the middle of the inner side of the telescopic sleeve 801. By rotating the locking nut 804, the end of the locking nut 804 can abut against the surface of the telescopic rod 803, thereby preventing the telescopic rod 803 from sliding inside the telescopic sleeve 801, thus achieving the function of fixing. This is the prior art and will not be elaborated on here.

[0025] Furthermore, the lower end of the telescopic rod 803 is rotatably connected to the support leg 806 via the locking pin 808. The bottom of the support leg 806 is fixedly connected to the plug pin 807. The end of the locking pin 808 is threadedly connected to the first wing nut 809. After tightening the first wing nut 809, the upper sides of the support leg 806 will deform, thereby squeezing the bottom of the telescopic rod 803, thus generating friction and preventing relative rotation between the support leg 806 and the telescopic rod 803. The plug pin 807 adopts a spiral drill tip design, which, together with the widened footplate at the bottom of the support leg 806, can withstand lateral impact without displacement on hard ground. The optional plug pin 807 can also be replaced with a rubber support foot.

[0026] Specifically, the opening component 9 includes a connecting plate 901, with a second threaded rod 902 threadedly connected to the middle of the connecting plate 901. The top of the second threaded rod 902 is rotatably connected to the middle of the bottom surface of the fixed plate 1, and a rotating handwheel 903 is fixedly connected to the bottom of the second threaded rod 902. Through the linkage design between the connecting rod 905 and the second threaded rod 902, the three legs 806 can be opened synchronously and at equal intervals, ensuring that the support surface is evenly stressed and forming a stable triangular structure. The second threaded rod 902 is made of self-lubricating POM material to reduce the operating torque of the handwheel.

[0027] Specifically, three sets of third rotating sleeves 904 are fixedly connected to the side of the connecting plate 901. Each of the three sets of third rotating sleeves 904 is rotatably connected to a connecting rod 905 through a rotating shaft. The top of the connecting rod 905 is rotatably connected to the second rotating sleeve 805 through a rotating shaft.

[0028] Furthermore, the diameter of the fixing rod 5 is larger than the diameter of the insertion hole 3. This design prevents the fixing rod 5 from slipping out of the insertion hole 3. Optionally, the length of the fixing rod 5 can be customized to avoid interference between the sampling smoke guns when they are installed.

[0029] Working principle: When the bracket is opened, first loosen the locking nut 804, pull the telescopic rod 803 to extend from the telescopic sleeve 801 to the required height, then tighten the locking nut 804 to fix it. Next, turn the handwheel 903 to drive the second threaded rod 902 to rotate, and push the three sets of support legs 806 to open synchronously to the preset radius through the connecting rod 905 and the third rotating sleeve 904 to ensure stable three-point support. Then, insert the plug pin 807 into the ground, and lock the angle between the support leg 806 and the telescopic rod 803 through the first butterfly nut 809 to enhance the anti-overturning ability. Then, place the smoke gun on the first semi-circular clamp 6, fasten the second semi-circular clamp 7, and turn the nut to fix it. Then, turn the fixing rod 5 to adjust the direction of the smoke gun so that it is aligned with the center of the flue. Use an external laser level to calibrate the verticality to ensure accurate sampling position.
