The invention discloses a device and method for measuring the density of phytoplankton and plants, aiming at solving the problems of inconvenient operation, high labor intensity and low measurement accuracy of the density measurement of phytoplankton and plants. The invention includes a quantitative cylinder and a collection cylinder, a one-way liquid discharge valve is installed at the lower end of the quantitative cylinder, a push piston is installed in the quantitative cylinder, a number of liquid inlet holes are arranged on the push piston, a one-way liquid inlet valve plate is installed on the liquid inlet hole, and a one-way liquid inlet valve sheet is installed on the liquid inlet hole. It can be rotatably installed at the lower end of the dosing cylinder, and the bottom surface of the collection cylinder is covered with a filter cloth, and several partitions are evenly distributed in the collection cylinder, and the partitions divide the collection cylinder into several collection boxes. The positioning cover is installed on the top of the cylinder, and the piston rod is connected to the push piston, and the piston rod runs through the positioning cover; the piston rod is provided with a rack, and the driving bevel gear and driven bevel gear are installed between the quantitative cylinder and the positioning cover, and the driving bevel gear is provided with Meshing gear, the meshing gear is matched with the tooth rack, and the impeller is installed on the driven bevel gear.
Description
technical field [0001] The invention relates to a metering device, more specifically, it relates to a device and method for measuring the density of phytoplankton. Background technique [0002] At present, the common method of measuring the density of marine phytoplankton is to manually drag the collection net, collect the phytoplankton into the collection net, and record the value on the flow meter with a pen and paper every time it is dragged, which is inconvenient to operate and has low accuracy. The trawl net is heavy, labor-intensive and labor-intensive. Contents of the invention [0003] The invention overcomes the disadvantages of inconvenient operation, high labor intensity and low measurement accuracy in measuring the density of phytoplankton and plants, and provides a device and method for measuring the density of phytoplankton and plants. The density measurement of phytoplankton and plants is easy to operate, reduces labor intensity, and greatly Improved measur...
