Description
Technical Field
[0001] The utility model relates to the technical field of smoke emission monitoring, and more specifically to a multi-point sampling rod structure. Background Art
[0002] Air pollution sources include fixed pollution sources and mobile pollution sources. Fixed pollution sources are divided into organized emission sources and unorganized emission sources. Organized emission sources refer to flues, chimneys and exhaust pipes, etc. Nowadays, in order to ensure a good living environment, the flue gas emitted by power plants during normal operation must meet domestic environmental protection emission standards, so regular sampling and testing of the gas in the flue is required;
[0003] At present, the method for sampling gas in long-distance and non-linear flues is: workers enter the flue and install sampling devices. This method requires workers to first set up a climbing frame in the flue according to the specified depth. After the climbing frame is installed, the workers can reach the specified position in the flue for subsequent installation work. The process is relatively cumbersome. At the same time, the method of construction in the flue is very likely to cause obstruction of the workers' vision and restriction of movement, which increases the difficulty of construction and is also prone to safety hazards. In addition, this method of sampling gas has a long construction period and high cost.
[0004] Therefore, a sampling structure in the flue is needed. This structure does not require workers to enter the flue to set up a climbing frame to install the sampling device as usual. The sampling of gases in the flue at different depths can be completed only outside the flue. Utility Model Content

The mounting plate 13 is fixed to the side wall of the flue in an inlaid manner, which provides a good supporting effect for the truss structure 11.
[0029] In one embodiment, the truss structure 11 includes an L-shaped first connecting rod 111 and a V-shaped second connecting rod 112, the long arm of the first connecting rod 111 is fixedly connected to the mounting plate 13, the vertex of the second connecting rod 112 is fixedly connected to the long arm of the first connecting rod 111, and a third connecting rod 113 is fixedly connected between the two supporting arms of the second connecting rod 112; a fourth connecting rod 114 is fixedly connected to both sides of the third connecting rod 113, and the other ends of the two fourth connecting rods 114 are fixedly connected to the mounting plate 13, respectively. The truss structure 11 composed of the first connecting rod 111, the second connecting rod 112, the third connecting rod 113 and the fourth connecting rod 114 forms a plurality of isosceles triangles as a whole, thereby ensuring the supporting effect of the sampling part 2, maintaining the stability of the sampling part 2 during operation, and thereby improving the working efficiency of the multi-point sampling part 2.
[0030] In one embodiment, the sampling portion 2 includes a plurality of sampling rods 21 of different specifications arranged in parallel.
[0031] In one embodiment, a through groove is opened on the mounting plate 13, a first flange 22 is installed in the through groove, a second flange 23 is detachably installed on the first flange 22, one end of each sampling rod 21 is fixedly connected to the second flange 23, and each sampling rod 21 extends to the side wall of the second flange 23 opposite to the truss structure 11.
[0032] Through the cooperation between the first flange 22 and the second flange 23, the sampling portion 2 can be taken out at any time, thereby improving the mobility of the sampling rod 21 structure and facilitating repair, maintenance and replacement.
[0033] In one embodiment, a filter 24 is installed at one end of each sampling rod 21 away from the second flange 23 , and a filter 24 protection cover 25 is installed on each filter 24 .
[0034] In one embodiment, the probe rod bracket 12 is Y-shaped, and the sampling part 2 is mounted on the upper end of the probe rod bracket 12 during the process of entering or moving out of the flue. The sampling part 2 slides on the probe rod bracket 12 during the process of pushing it into the flue, thereby improving the stability of the multi-point sampling rod structure during the disassembly and assembly process, and effectively reducing the collision between the sampling part 2 and the side wall of the flue. It should be noted that the probe rod bracket 12 is not limited to the Y-shape, and its upper end portion can also be U-shaped or other shapes.
[0035] In one embodiment, the distance between each sampling rod 21 and the adjacent sampling rod 21 is equal.
[0036] In one embodiment, two adjacent sampling rods 21 are connected by a plurality of locking mechanisms 3, each of which includes a partition block 31; each partition block 31 is a hollow structure, and a wire reel is installed in the internal space of each partition block 31, and a connecting belt 32 is wound around the wire reel. An opening is provided on one side of the partition block 31, and the free end of the connecting belt 32 passes through the opening and extends to the outside of the partition block 31. The partition block 31 is provided with a male surface of Velcro below the opening, and the surface of the connecting belt 32 is provided with a female surface of Velcro.

[0039] In one embodiment, the contact surface between the partition block 31 and the sampling rod 21 is arc-shaped, and the arc-shaped surface of the partition block 31 is matched with the surface of the sampling rod 21. The surface matched with the surface of the sampling rod 21 increases the fit between the partition block 31 and the sampling rod 21, thereby further improving its stability.
[0040] In one embodiment, a free end of the connecting strap 32 is fixedly connected to a Type buckle 33, The width of the buckle 33 is greater than the width of the opening.
