Water level monitoring device for water conservancy project

Abstract

The invention discloses a water level monitoring device for water conservancy projects, and relates to the technical field of water level monitoring for water conservancy projects, the water level monitoring device comprises a water level measuring rod, a base fixedly connected to the bottom end of the water level measuring rod and an alarm arranged at the top end of the water level measuring rod, the upper part of the water level measuring rod is sleeved with a lock-free push switch, and a rod body of the water level measuring rod is movably sleeved with a buoyancy table; the outer wall of the buoyancy table is sleeved with an inverted ring plate used for preventing the buoyancy table from being separated from the water surface. A guide assembly used for sliding of the buoyancy table and the water level measuring rod is arranged in the inner ring of the buoyancy table. Through the arrangement of the buoyancy table and the inverted ring plate, the buoyancy table can be prevented from being blown by wind power to be separated from the water surface while the buoyancy is improved, the buoyancy table can stably float on the water surface all the time, and the alarm can be stably triggered; the buoyancy table can horizontally rotate while floating through the guide assembly, and the impact force of water flow is counteracted through the buoyancy table capable of horizontally rotating.

Description

technical field [0001] The invention relates to the technical field of water level monitoring for water conservancy projects, in particular to a water level monitoring device for water conservancy projects. Background technique [0002] The construction of water conservancy projects can control water flow, prevent floods, and adjust and distribute water volume to meet the needs of people's life and production for water resources; water level monitoring is an indispensable link in the inspection of water conservancy projects. Water level monitoring is mainly Monitor the depth of water bodies intercepted by dams and other water conservancy projects; [0003] At present, water level monitoring mostly adopts a water level measuring rod with a buoyancy plate in the river channel. When the buoyancy plate moves up and down following the change of the water level, it is easy to trigger the alarm on the water level measuring rod; but this kind of water level monitoring structure, due...

Problems solved by technology

[0003] At present, water level monitoring mostly adopts a water level measuring rod with a buoyancy plate in the river channel. When the buoyancy plate moves up and down following the change of the water level, it is easy to trigger the alarm on the water level measuring rod; but this kind of water level monitoring structure, due to The weight of the buoyancy board is light. In a windy day, the buoyancy board is easily blown by the wind, and it is stuck on the water level measuring rod when it is separated from the water surface. Due to the normal triggering of the device, it is impossible to timely give an alarm prompt for the change of the water level; therefore, it is necessary to improve the above problems
