A hydrological monitoring device

Abstract

The invention relates to a hydrological monitoring device, which comprises a cylindrical first cylinder and a second cylinder arranged side by side, a one-way pay-off mechanism is fixedly arranged at the bottom of the first cylinder, and a floating ball is arranged in the second cylinder. The diameter of the floating ball is smaller than the inner diameter of the second cylinder. The first cylinder and the lower part of the second cylinder are provided with a plurality of water inlets, and the outside of the water inlets is provided with a protective device. The one-way pay-off mechanism includes a shell and a The rotating shaft and the first winding wheel fixedly arranged on the rotating shaft, both ends of the rotating shaft are connected with the casing through bearings, a ratchet wheel is fixedly arranged on the rotating shaft, and a pawl matching the ratchet wheel is arranged inside the casing. The first pulley is set on the first pulley; the first pulley is set on the top of the first cylinder, the second pulley is set on the top of the second cylinder, and the top of the first pulley goes around the first pulley, the second pulley and the floating ball in turn. top connection.

Description

technical field [0001] The invention relates to an indicating or measuring device for a liquid level or a flowing solid material level, in particular to a hydrological monitoring device. Background technique [0002] At present, the following two methods are generally used for river water level measurement, the traditional water gauge and the electronic water level gauge. The traditional water gauge is a scale with a scale set in the river channel. With the change of the water level in the river channel, a special person will read the real-time water level. Modern hydrological surveys use electronic technology water level gauges, mainly including float type, bubble type, radar type, etc., all of which require special equipment for data collection and transmission, and are generally set up in special hydrological stations and water level measuring stations. [0003] At present, the water level measurement of open waters generally uses traditional water gauges for manual trac...

AI Technical Summary

Problems solved by technology

The lowest water level of rivers and lakes, the lowest tide level of beaches, and the lowest water level of ditches are important parameters for river and lake health assessment, beach development planning and channel water consumption calculation. Traditional measurement methods are expensive and inconvenient

[0004] Hydrological monitoring devices in the prior art, such as a magnetic suction type open channel minimum water level self-recording ruler and its method disclosed in the Chinese invention patent No. CN201310423676.7, but it has some disadvantages, 1. The resistance of the ring is too large, so that the ring cannot move up smoothly, and the final structure is inaccurate; 2. The shape of the floating block and the cylinder are compatible, and there will be jamming due to the deviation of its stroke; 3. The sewage in the river Too much mud and weeds, etc., will cause debris to accumulate in the device, affecting its normal use
