Self-recording ruler and its method for the minimum water level of jammed open channel

Abstract

The invention discloses a jammed open-channel lowest-water-level self-recording scale and method. The scale comprises a main frame, a graduated scale body, a sleeve ring, a tooth space face, a reading pin, a roller, a plumb and a hanging line. The reading pin and the roller are mounted at the top end of the main frame, one side face of the main frame is the tooth space face, the sleeve ring is sleeved on the periphery of the main frame, one end of the graduated scale body is connected with the sleeve ring, the other end of the graduated scale body crosses the roller via the front of the main frame to be connected with the plumb through the hanging line, the plumb is in a suspension state when being on the back of the main frame, the reading pin is arranged on the front of the main frame, and the graduated scale body is arranged inside the reading pin. The scale can automatically record lowest water levels of open waters such as river channels, sea beaches, lakes and channels, is free of power consumption, manual tracking and dependence on any other equipment, and has the advantages of simple structure, low cost, convenience in manufacturing, high measuring precision and the like as compared with traditional means such as water-level electric measurement and manual tracking reading, thereby having broad application prospect.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering and marine engineering measuring facilities, in particular to a self-recording ruler for the minimum water level of a jammed open channel and a method thereof. Background technique [0002] At present, the water level measurement of open waters generally uses traditional water gauges for manual tracking and reading or electronic water level gauges for whole-process records. The former needs to arrange more inspectors to continuously read the water level of the water gauge, and the work intensity is high and the error is relatively large; the latter needs to use special equipment for data collection and transmission, which are generally set up in special hydrological stations and water level stations. , high investment and high operating costs. The lowest water level of rivers and lakes, the lowest tide level of beaches, and the lowest water level of ditches are important parameters fo...

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. Therefore, it is urgent A self-recording ruler for the minimum water level of an open channel that is simple, accurate and low in work intensity is needed
