Abstract

The invention belongs to the technical field of environmental monitoring, particularly relates to a rainwater sampling device for environmental monitoring, and provides the following scheme for solving the problem that an existing sampling device is prone to overflow: the rainwater sampling device comprises a box body, sliding grooves are formed in the inner walls of the two sides of the box body,sliding blocks are slidably connected in the sliding grooves, and first springs are fixed between the sliding blocks and the inner walls of the sliding grooves; and a bearing ring is fixed between the two sliding blocks, a water collecting basin is fixed to the inner wall of the bearing ring, a plurality of stress plates are fixed to the top of the circumferential outer wall of the water collecting basin, the stress plates are wing-shaped, a water outlet is formed in the bottom of the water collecting basin, a guide groove is formed in the bottom of the circumferential inner wall of the watercollecting basin and is in a threaded shape, and a sampling mechanism is arranged in the box body. According to the rainwater sampling device, when rainwater drips onto the stress plate, the stress plate drives the water collecting basin to rotate, and the water collecting basin drives accumulated water flow to rotate, so that the water flow forms a vortex shape, the accumulated water flow can beaccelerated to be left from the water outlet and collected, and the phenomenon that the water flow overflows reversely is prevented.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a rainwater sampling device for environmental monitoring. Background technique [0002] The precipitation sampler used by the environmental detection department or the meteorological detection department is used to measure the pH value and conductivity of the collected rainwater for scientific researchers to analyze and study the rainwater. Rainfall is a natural phenomenon, but because of the pollution of the atmospheric environment, it has become a source of pollution that cannot be ignored. Therefore, in order to grasp the characteristics of rainwater quality in different periods of the rainfall process, it is necessary to use sampling and detection devices to study rainwater. [0003] When the existing precipitation sampling and detection equipment is used in heavy rain, in order to quickly sample rainwater, the general water collection basin is funnel-shaped...
