Description

Technical Field

[0001] The utility model relates to the technical field of environmental monitoring, in particular to an environmental comprehensive sampler. Background Art

[0002] The environmental comprehensive sampler is a common sampling device used to collect gas components in the air. It mainly collects quantitative gas by generating negative pressure through the internal air pump, collects harmful gas components in the air by solution absorption method, and collects particulate matter components in the atmosphere by filter membrane weighing method, providing reference data for air quality management, weather forecasting, and air health risk assessment.

[0003] Traditional environmental comprehensive samplers are equipped with a placement box for special absorption bottles, but the space in the placement box is limited and cannot accommodate other types of absorption bottles, drying bottles, and blank sample bottles for reference and comparison, which causes certain inconveniences during sampling. Utility Model Content

[0005] By adopting the above technical scheme, the interface part is used to install the TSP cutter for collecting particulate components in the atmosphere, the placement box is used to place a special absorption bottle to absorb harmful gas components in the air, and the connecting rod is installed on the handle part through a fixing clamp, which effectively avoids the interference of the connecting rod when the sampler housing and the TSP cutter and the absorption bottle are installed. The placement rack is installed on the side surfaces on both sides of the sampler housing through the connecting rod to increase the placement position of the absorption bottle, and can also be used to place absorption bottles and drying bottles of different models; when using the solution absorption method, a blank sample bottle is usually added for data reference. The blank sample bottle only adds absorption liquid but does not come into contact with the gas in the air. As a reference for the experiment, the blank sample bottle is placed on the placement rack so that it is at the same level as other absorption bottles. The absorption liquid inside is also affected by the vibration of the air pump, thereby improving the rigor of the sampling experiment.

[0006] The utility model is further configured that the fixing clamp is provided with a mounting portion and clamping portions provided at both ends of the mounting portion, and both ends of the connecting rod are provided with clamping grooves adapted to the clamping portions, and the fixing clamp is clamped to the connecting rod through the clamping grooves.

[0007] Furthermore, the mounting portion is generally U-shaped, an arc groove matched with the handle portion is provided on the inner side of the mounting portion, a connecting rod is provided with a connecting column in the slot, and the clamping portion is provided with a trapezoidal groove matched with the connecting column.

[0008] By adopting the above technical solution, the fixing clip is integrally formed of rubber material and is installed in the connecting rod by snap-fitting. The contact area between the fixing clip and the connecting rod is increased by the mounting column, thereby preventing the fixing clip from detaching from the connecting rod.

[0009] The utility model is further configured such that the placement rack includes a back plate, and an upper plate and a lower plate perpendicular to the back plate, the back plate is provided with a steering portion, and the back plate is rotatably connected to the connecting rod through the steering portion, the upper plate and the lower plate are respectively provided with inner holes a and inner holes b coaxially distributed with each other, and the inner holes a and the inner holes b are combined to form the installation groove.

[0010] Furthermore, the diameter of the inner hole a is larger than that of the inner hole b, and both the inner hole a and the inner hole b are provided with rubber rings for buffering.

[0011] By adopting the above technical solution, the absorption bottle passes through the inner hole a and abuts against the lower plate, so that when the absorption bottle abuts against the lower plate, it is positioned by the upper plate to prevent the absorption bottle from tipping over and breaking. The placement rack is welded from sheet metal parts, and the rubber ring is used to buffer the friction between the placement rack and the body of the absorption bottle.

[0012] The utility model is further configured such that the height H of the back plate is not greater than half of the total length L of the connecting rod.

[0013] By adopting the above technical solution, when the connecting rod is removed, the placement rack can be folded on the connecting rod, thereby reducing the overall occupied space and facilitating packing and transportation.

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

[0015] 1. The connecting rod is installed on the handle through a fixing clamp, which effectively avoids interference between the connecting rod and the sampler housing, TSP cutter, and absorption bottle when they are installed. The placement rack is installed on the sides of both sides of the sampler housing through the connecting rod to increase the placement position of the absorption bottle. It can also be used to place different types of absorption bottles and drying bottles.

[0016] 2. The rack can be folded onto the connecting rod to reduce the overall space occupied and facilitate packing and transportation.
