Description

A water level monitoring device for water conservancy projects

Technical Field

The utility model relates to the technical field of water conservancy engineering equipment, in particular to a water level monitoring device for a water conservancy engineering.

Background Art

Water conservancy projects mainly include hydrological regulation projects, water resources development projects, water conservancy facilities construction projects and soil and water conservation projects. Their main function is to use natural water resources to achieve the purposes of power generation, water storage, irrigation, flood control, etc. In the river field, natural water resources are usually regulated and controlled by building reservoirs. Since the water level of the reservoir directly affects the storage of water resources in the reservoir, in order to maintain the monitoring of the reservoir water level, the existing technology often uses hydrological monitoring base stations and other water level monitoring equipment to monitor the reservoir water level in real time. For example, an existing JYB-SW type water conservancy project hydrological monitoring base station includes a pillar installed on the ground and a main box installed on the pillar. The main box is powered by solar panels, and the water level changes are measured non-contactly through a real-time monitoring camera probe, and the data is analyzed and processed by the main machine. The monitoring data is transmitted to the staff's computer and other signal receiving devices in real time through wireless signals, thereby realizing real-time monitoring of the reservoir water level. The following problems exist in the existing technology:

In order to prevent water from entering in an open air environment, the connection between the box body and the box door of the existing water level monitoring device for water conservancy projects usually adopts a square gasket made of a waterproof strip as a sealing structure. Since the existing waterproof strips are mostly made of soft materials such as rubber and the existing waterproof strip installation methods are mostly to directly drill holes on the outside of the waterproof strip and drive bolts in or to use glue to bond, the above two installation methods will damage the contact surface between the waterproof strip and the box door and it is not convenient to straighten the waterproof strip and install it at an angle completely parallel to the box door. Therefore, it is easy to leave a gap between the box door and the waterproof strip, thereby reducing the sealing effect. In addition, the elasticity of the existing waterproof strip is easy to disappear after being used for too long, causing the waterproof strip to collapse, thereby causing water to enter the inside of the box, and then causing the equipment inside the box to be damaged by water.
