A water level gauge for the highest water level in a river

Abstract

The invention relates to a maximum water level gauge of a river course, which comprises a cylindrical cylinder body, a one-way pay-off mechanism fixedly arranged at the bottom of the cylinder body and a floating ball arranged in the cylinder body, the diameter of the float ball is smaller than the inner diameter of the cylinder body, and the cylinder body The lower part is provided with a plurality of water inlets, and a protective device is arranged outside the water inlet. The one-way pay-off mechanism includes a housing, a rotating shaft arranged in the housing and a first winding wheel fixed on the rotating shaft. Both ends of the rotating shaft pass through bearings and The casing is connected, and a ratchet wheel is fixedly arranged on the rotating shaft. A pawl matching the ratchet wheel is arranged inside the casing. A first cable is arranged on the first reel, and the top of the first cable is connected to the bottom of the floating ball, and the top of the floating ball It is connected to the top of the cylinder through a connecting line. The present invention uses a floating ball to pull the cable for recording, reducing resistance and errors, and ensuring that the floating ball can rise steadily with the water level of the river. The ball rises freely without the resistance of the cylinder.

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 maximum water level gauge for a river. 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. When the flood control department needs to know the highest water level in the river, a method usually taken is ...

AI Technical Summary

Problems solved by technology

[0003] Among the above methods, the first method needs to arrange more inspectors along the river, and needs to read the water level continuously, and the work intensity is high.

The second method requires a professional survey team to enter the field, and the investigation of flood traces in the field is related to the memory of the interviewee and the retention of shore traces

The third method is limited by conditions and needs to be equipped with special equipment and special management rooms. There are relatively few water level measuring stations and hydrological stations on the river, especially in mountainous rivers, where there are very few water level measuring stations. , the maximum water level of each flood can only be calculated, but cannot be accurately grasped

However, there are some disadvantages. 1. The teeth have too much resistance to the ferrule, so that the ferrule cannot move up smoothly, and the final structure is inaccurate; 2. The shape of the floating block and the cylinder are compatible. Due to the deviation of its stroke, There will also be a phenomenon of jamming; 3. There are too many sludges and weeds in the river water, which will cause silting and debris in the device, which will affect its normal use
