Water level early warning device for hydraulic engineering construction management

Abstract

The invention discloses a water level early warning device for hydraulic engineering construction management, which belongs to the technical field of hydraulic engineering. The water level early warning device comprises a base, the upper end of the base is fixedly connected with a winding reel and a supporting arm, one end of a traction cable is wound on the winding reel, and the end, away from the winding reel, of the traction cable is fixedly connected with a detection floater, and the middle section of the traction cable is fixedly connected to anoffset measurer; the water flow at the water inlet can be judged according to the output current of the hydroelectric generator, data processing is carried out through the monitor, the water level can be predicted according to the water flow, and therefore the early warning effect of the early warning device is effectively improved; according to the scheme, the traction cable is fixed through the offset measurer, so that the length of the traction cable between the offset measurer and the detection floater is adjustable, the adjustment range is large, the application range of the early warning device is effectively widened, the early warning device can be arranged at different heights and positions, and the applicability of the early warning device is improved.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, and more specifically relates to a water level early warning device for water conservancy construction management. Background technique [0002] Water conservancy engineering is a project built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and rejuvenating profits. It is also called water engineering. Water is an indispensable and precious resource for human production and life, but its natural existence The state does not fully meet the needs of human beings. Only by building water conservancy projects can water flow be controlled, floods prevented, and water volume adjusted and distributed to meet the needs of people's life and production for water resources. Water conservancy projects require the construction of dams, dikes, Different types of hydraulic structures such as spillways, sluices, water intakes, canals,...

AI Technical Summary

Problems solved by technology

[0004] During the diversion process, it is necessary to monitor the water level around the construction area, so as to avoid the threat of excessive water level to the construction area. In the prior art, electronic water level gauges and water gauges are usually used to monitor the water level. These monitoring devices are troublesome to install, because The limit of its own length is applicable to a small range, and with the different monitoring requirements required by the construction progress of water conservancy projects, the use of traditional electronic water level gauges and water level gauges requires the purchase of multiple models to meet the monitoring requirements around the construction area during the entire construction process. In the prior art, there is also an ultrasonic water level monitoring and early warning device. The use of ultrasonic positioning requires a stable water surface, and because the ultrasonic detection and early warning device is relatively precise, it is easily affected by the environment and waves, and the measurement results are not accurate enough and have low reliability. The existing water level monitoring and early warning devices can only monitor the water level in real time, and the early warning effect is not good
