Reinforcing device of bracket of medium-volume sampler

Abstract

The invention discloses a reinforcing device of a bracket of a medium-volume sampler. The reinforcing device consists of three stainless steel pipes with the same dimension, three movable pipes, three pipeline clamps and three connecting screw nuts, wherein the stainless steel pipes are used for connecting two adjacent legs of the three-legged bracket of the sampler; the movable pipes are placed in the middles of turn-up parts of the stainless steel pipes, and are fixed on the outer sides adjacent to the legs of the three-legged bracket by the connecting screw nuts; the movable pipes rotate upwards by 180 degrees, and lean against the three-legged bracket of the sampler in parallel; and the other ends of the movable pipes are fixed together with the three-legged bracket of the sampler by the pipeline clamps. The device can reinforce the medium-volume sampler, can prevent the medium-volume sampler from being blown down, reserves the characteristics of simple structure, small storage space and convenience in dismounting and carrying, and can meet the requirement on atmospheric particulate research sampling work or routine atmospheric environment monitoring work.

Description

technical field [0001] The invention relates to a bracket reinforcement device for a medium-flow sampler, which is a bracket reinforcement device for a medium-flow sampler with simple structure, portability, detachability, small storage space, and stainless steel as the main material, and is suitable for scientific research sampling work or routine Atmospheric particulate matter sampling equipment in atmospheric environmental monitoring work - the fixation of medium flow samplers. It belongs to the technical field of environmental monitoring equipment. Background technique [0002] Various brands of medium-flow samplers that meet national standards can be purchased in the market, such as Laoying 2030 medium-flow intelligent TSP sampler, Wuhan Tianhong TH-150 series intelligent medium-flow total suspended particle sampler, etc. Generally speaking, the flow samplers of various brands are composed of the following three parts: replaceable sampling head, sampler body (air pump)...

AI Technical Summary

Problems solved by technology

The support of the medium flow sampler is generally an ordinary retractable stainless steel tripod support, but the sampling of atmospheric particulate matter is generally carried out outdoors, which is easily affected by weather conditions

According to the sampling experience of the sampling personnel, the medium-flow sampler is easily blown down by the strong wind during the sampling process, which not only causes damage to the instrument, but also leads to sampling failure, which cannot meet the needs of atmospheric particulate matter sample collection under unattended conditions

In addition, the material of the sampling bracket is composed of stainless steel and plastic, and the plastic will age and break easily under long-term exposure to sunlight, making the whole bracket not strong enough
