Hourglass type water quality detector-based quantitative metering device

Abstract

The invention discloses an hourglass type water quality detector-based quantitative metering device which structurally comprises a buoyancy fixed bracket, a microbial preparation metering device and amicrobial preparation injection device, wherein the buoyancy fixed bracket is provided with a telescopic adjustment rod and a buoyancy ball; the microbial preparation metering device is provided withan air pump transmission box and a microbial preparation loading tank; the microbial preparation injection device is provided with an injection head and an air pressure extrusion device. The hourglass type water quality detector-based quantitative metering device has the beneficial effects that a sunscreen insulation layer of the microbial preparation loading tank can guarantee the activity of amicrobial preparation; the microbial preparation is continuously fed into water through timing work of an air pump, so as to avoid a counter-productive situation of water eutrophication due to excessive feeding each time; in addition, the microbial preparation is fed through a dropper, so that the feeding amount can be controlled more conveniently; the hourglass type water quality detector-based quantitative metering device is also applicable to powdered or aqueous microbial preparations.

Description

technical field [0001] The invention relates to the field of water quality detection, in particular to a quantitative metering device based on an hourglass-type water quality detector. Background technique [0002] Aquaculture is one of the most extensive aquaculture industries in my country. Although the value of aquaculture has declined in recent years, the price of aquaculture equipment is still slightly high. However, in aquaculture, the quality of water Requirements and maintenance are particularly important, so higher requirements are required in terms of water quality management. [0003] Aiming at the current water quality detection and metering devices for aquaculture, a relative plan has been formulated for the following problems: [0004] In the aquaculture industry, water quality is usually maintained and improved by adding microbial preparations, but excessive microbial preparations will lead to excellent water quality. Although excellent water quality can accel...

Problems solved by technology

[0004] In the aquaculture industry, water quality is usually maintained and improved by adding microbial preparations, but excessive microbial preparations will lead to excellent water quality. Although excellent water quality can accelerate the rapid growth of fry in the seedling stage, it will accelerate the water quality in the later stage. The deterioration of the environment will cause troubles in breeding management, which is not conducive to long-term development, but the effect will not be achieved if there is less input
