Description

Technical Field

[0001] The utility model relates to the technical field of TSP samplers, in particular to a TSP comprehensive sampler with high precision. Background Art

[0002] Total suspended particulate matter refers to particles suspended in the air with an aerodynamic equivalent diameter of ≤100μm. Other common concepts of the same type include PM10, PM2.5, etc., which all refer to dust particles.

[0003] When conducting TSP sampling, generally one point is required in the upwind direction, target area, and downwind direction. If there are sensitive points, additional points will be added at the sensitive points. Since some locations are lower or there are obstructions nearby, the height of the sampler needs to be adjusted to improve the sampler's collection accuracy.

[0004] The sampler in the prior art usually has a bracket installed at the bottom, but the installation of the bracket is troublesome, time-consuming and labor-intensive, and the bracket is heavy and bulky, making it inconvenient to carry.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0008] Furthermore, each of the supporting legs adopts a multi-section foldable telescopic rod, and one end of each of the supporting legs away from the corresponding connecting block is fixedly connected to a protective pad.

[0009] Furthermore, each arc-shaped groove opened in the fixing block 1 has a certain angle with the sampler body, and each arc-shaped groove opened in the fixing block 2 is parallel to the sampler body.

[0010] Furthermore, a fixing pad is provided on the top of each connecting block, each fixing pad is made of soft rubber material, a bolt is inserted into the interior of each fixing pad, and the outer surface of each bolt is threadedly connected to the corresponding threaded hole.

[0012] Furthermore, a folding handle is installed inside the sampler body, and a display screen and operation buttons arranged at equal distances are installed on the front of the sampler body.

[0013] Furthermore, a mounting groove is provided inside the sampler body, slots arranged at equal distances are installed inside the mounting groove, and bases arranged at equal distances are installed on the bottom surface of the sampler body.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model is provided with components such as a connecting block, a fixing block 1, a fixing block 2 and a supporting leg. When the device is used, when it is necessary to support the sampler, the supporting leg is rotated from one fixing block to contact the arc groove of the fixing block 2, and then the internally folded supporting leg is pulled out and contacts the ground. When it is necessary to store the supporting leg, the supporting leg is now contracted and then rotated to the arc groove of one fixing block for storage, thereby achieving the effect that the device can conveniently raise the height of the sampler and support it according to needs.

[0016] 2. The utility model is provided with components such as a fixing pad, a bolt, a fixing block 1 and a threaded hole.
