Automatic precipitation sampler

Abstract

The invention aims to provide an automatic precipitation sampler which comprises a sampling bottle, a sampling bottle sensor, a pressure sensor, a detection funnel, a rain collection funnel, a cover, a rotary motor, a lifting rod, a lifting rod motor and a water injection mechanism, wherein the lifting rod is mounted below the cover; the lifting rod motor drives the lifting rod so that the cover moves up and down; the rotary motor is connected with the cover and drives the cover to rotate; the cover covers the rain collection funnel; the rain collection funnel is communicated with the water injection mechanism; the sampling bottle is arranged by corresponding to the water injection mechanism; the sampling bottle sensor is mounted on the water injection mechanism to detect whether the sampling bottle is full of water or not; the detection funnel is arranged beside the rain collection funnel; a pipeline blocking rainwater is connected below the detection funnel; a bypass pipe is mounted on the pipeline; and the pressure sensor is mounted on the bypass pipe. The automatic precipitation sampler provided by the invention can automatically collect rainwater in precipitation and automatically stop sampling after the rain stops; and after the collection, the precipitation automatic sampler can store the sample perfectly and record the precipitation-related data.

Description

technical field [0001] The invention relates to a device for collecting rainwater. Background technique [0002] Acid rain will "acidify" the environment and cause serious harm to human landscapes such as soil, water bodies, forests, buildings, and historical sites. my country covers Sichuan, Guizhou, Guangdong, Guangxi, Hunan, Hubei, Jiangxi, Zhejiang, Jiangsu, and Qingdao, etc. In some provinces and cities, the acid rain area with an area of ​​more than 2 million square kilometers not only caused great economic losses, but also threatened the survival and development of human beings. To prevent and control acid rain, the precipitation water quality must first be tested to understand the coverage and severity of acid rain, and provide the necessary basis for the prevention and control of acid rain. Accurate collection of precipitation samples is the key to water quality analysis. [0003] At present, most of the domestic precipitation samplers are provided with a sealing co...

Problems solved by technology

The disadvantage of this device is that the structure is too simple, there is only one sampling container, although it does not need electricity and is low in cost, its reliability is poor, and many uncertain factors are not considered, so the practicability is very poor

The disadvantage of this device is the use of the rain sensor. The principle and performance of the rain sensor are not yet mature, the service life is not ideal, and the price of the product is also very expensive. high
