Water level monitoring device and method with alarm function

Abstract

The invention discloses a water level monitoring device and method with an alarm function. The water level monitoring device comprises a mounting block, a cavity is formed in the mounting block, a first tuning fork is fixedly installed in the cavity, and a second tuning fork with the same vibration frequency as the first tuning fork is further fixedly installed at the upper end of the mounting block. A metal cover body covers the outer part of the second tuning fork in a sealing manner, the two fork arms of the second tuning fork are just not in contact with the inner wall of the metal cover body, and a through hole communicated with the cavity is also formed in the surface of the mounting block in the metal cover body. A longitudinal first mounting groove is formed in the bottom of the cavity, and an impact block used in cooperation with the first tuning fork is vertically connected into the first mounting groove in a sliding mode. Transmission can be rapidly triggered when the waterlevel is lower than a warning line, an alarm is given to remind a worker to make a response in time, a pure mechanical structure is adopted for transmission in the process, electric power consumptionis not needed, energy conservation and environmental protection are achieved, the monitoring sensitivity is higher, and use is more convenient.

Description

[0001] This application is a divisional application of a water level monitoring device with an alarm function with an application date of November 14, 2019 and an application number of CN 201911110618.2. technical field [0002] The invention relates to the technical field of water level monitoring, in particular to a water level monitoring device and method with an alarm function. Background technique [0003] The principle of hydroelectric power generation is to use the water flow to drive the water turbine to rotate, so that the water turbine drives the generator to convert mechanical energy into electrical energy, and finally the power is sent to the user through power transformation and power transmission and distribution equipment. [0004] Hydropower stations usually need to install a water level monitoring device at the water outlet when generating hydropower to prevent insufficient water flow energy supply when the water level is low. The existing water level monito...

Problems solved by technology

The existing water level monitoring equipment is not sensitive enough to the change of water level. When the water level is lower than the warning line, the staff cannot be notified quickly to make emergency adjustments, which is inconvenient to use.
