Stop mechanism and outdoor water quality monitoring device

Abstract

The invention discloses a stop mechanism and an outdoor water quality monitoring device. The stop mechanism is used for unidirectional locking of a second reel, and the stop mechanism comprises a ratchet wheel, the ratchet wheel is coaxially installed and fixed on a fourth reel, and the ratchet wheel is provided with countless tooth grooves; the tooth grooves can be clamped and assembled with oneend of the ratchet wheel; a first hinge block and a second hinge block are respectively arranged on the ratchet wheel, a first hinge pin is installed on the first hinge block, the second hinge block is hinged to the side wall of a stop installation groove in a stop sliding block through a third hinge pin, the first hinge pin is assembled and fixed to one end of a first compression spring, the other end of the first compression spring is assembled and fixed to a second hinge pin, and the second hinge pin is hinged to the inner wall of the stop installation groove; stop sliding strips are arranged on the two sides of the stop sliding block respectively, are clamped with stop sliding grooves formed in the sliding base and can be assembled in a sliding mode; and the sliding base is fixed to afirst partition plate. According to the invention, basic water quality data can be automatically collected, and the collected data is sent to the terminal in real time in a wireless manner.

Description

technical field [0001] The invention relates to water quality monitoring technology, in particular to a stop mechanism and an outdoor water quality monitoring device. Background technique [0002] Water is the source of life, and the quality of water in general water sources directly affects the surrounding environment and the health of drinking groups. With the increasingly strict environmental regulations, the protection of water quality has become an important task of the environmental protection department. At present, it mainly conducts regular water quality spot checks and tests for some water sources, rivers, lakes, etc., so as to monitor the quality of water quality, and at the same time, timely detect pollution and test the effect of water quality control. [0003] Although a very comprehensive data analysis can be obtained through the laboratory by means of regular sampling and testing, in the case of relatively strong fluidity, the pollutants may have been washed...

AI Technical Summary

Problems solved by technology

[0003] Although a very comprehensive data analysis can be obtained through the laboratory through regular sampling and testing, in the case of relatively strong fluidity, the pollutants may have been washed away within the sampling interval, which makes it difficult to pollute the river in the later stage. Once the source is found, it will be difficult to pursue accountability

In addition, for key water areas, such as water sources or key lake pollution control areas, they are generally remote and large in size.

If the sampling period is too long, there are obviously great hidden dangers, especially in water sources. Once the sampling period reaches less than twice a month, it will be too late to discover water quality problems. At this time, thousands of drinkers have already been affected damage to health

However, if the sampling frequency is too high, it will require a lot of manpower and material resources, which is obviously not in line with the current basic environment.
