Self-opening/closing quantitative bottle-dividing rainwater sampler

Abstract

The invention discloses a self-opening / closing quantitative bottle-dividing rainwater sampler. The rainwater sampler comprises a box body, a plurality of rail rods are mounted on the inner wall of the box body at equal intervals, a rail groove is formed in the bottom wall of each rail rod, a sliding pipe sleeve is slidably mounted in each rail groove, a sampling pipe is slidably inserted into the lower end of each sliding pipe sleeve in a sealed mode, a spring pipe is installed at one end of each rail groove, the multiple spring pipes are connected with the side walls of the multiple sliding pipe sleeves correspondingly, multiple sampling bottles are symmetrically placed on the inner bottom wall of the box body, and multiple drainage pipes are embedded in the inner bottom wall of the box body at equal intervals. The spring pipes push the sliding pipe sleeves to slide in the rail grooves under the action of hydrodynamic force, automatic fixed-point sampling is achieved in the sampling grooves through the gravity of the sampling pipes, automatic quantitative sampling is achieved through cooperation of the sampling bottles and the sampling pipes, electric control or manual sampling is not needed, and the sampler is more accurate and reliable.

Description

technical field [0001] The invention relates to the field of rainwater sampling, in particular to a self-opening and closing quantitative bottle-dividing rainwater sampler. Background technique [0002] The collection and storage of rainwater is one of the important links of environmental testing. The pollution degree of air environment and water environment can be analyzed by detecting the content of various substances in rainwater. [0003] The existing rainwater collection usually adopts electric control collection. In rainy days, the controller opens the water inlet to enter the water, and then injects rainwater into the sampling bottle through the controller, various sensors, and drivers to achieve quantitative sampling. However, the energy consumed by electric control More, and the power control system is easily damaged by moisture in the rain environment, and the reliability is low. Contents of the invention [0004] The purpose of the present invention is to solve...
