Abstract

The invention discloses a water quality monitoring sampling device and method. The water quality monitoring sampling device comprises a fishing rod, a sampling bottle and a float bowl. The sampling bottle comprises a valve body, a valve element and a bottle body. The top of the bottle body is provided with a water inlet. The valve body comprises a cylindrical shell. The top face of the shell is provided with a hanging hole. The side wall of the shell is provided with water inlet windows. The lower end of the shell is connected with the upper end of the bottle body in a threaded mode. The valve element is vertically movably arranged in the shell. The float bowl is connected with the valve element through a pull wire penetrating through the hanging hole. The fishing rod is connected with the valve body through a fishing wire. When the valve element moves to the lowest position in the shell, the valve element blocks the water inlet of the bottle body; when the valve element moves to the uppermost position in the shell, the water inlet windows in the shell are communicated with the water inlet of the bottle body. The sampling device is adopted for the water quality monitoring sampling method. The water quality monitoring sampling device and method are suitable for being used under the condition that the requirement for the sampling depth exists but is not very precise, free of electric control, simple in structure and convenient to sample.

Description

technical field [0001] The invention relates to a water quality monitoring sampler and a sampling method. Background technique [0002] Chinese Patent No. 200910014277.9 discloses an automatic layered quantitative sampler for deep-water plankton, which includes a bracket, a sampling unit, and a control unit. It is characterized in that: the bracket includes a frame and a support plate arranged in the frame, and the sampling unit , the control unit is arranged on the support plate; the sampling unit includes a submersible pump, a multi-way shunt, a solenoid valve, an electronic flow meter, a plankton filter, a sample collection pipe and a sampling valve, and the submersible pump is connected to the multi-channel through a connecting pipe. The water inlet of the multi-way splitter is connected, and each water outlet of the multi-way splitter is respectively connected to the water inlet of the corresponding plankton filter, and the lower end of the plankton filter is provided w...
