Description

Technical Field

[0001] The utility model mainly relates to the field of water conservancy project liquid level monitoring equipment, in particular to a water conservancy project liquid level monitoring device. Background Art

[0002] Projects built to eliminate water disasters and develop and utilize water resources. According to their service objects, they are divided into flood control projects, farmland water conservancy projects, hydropower projects, waterway and port projects, water supply and drainage projects, environmental water conservancy projects, and sea reclamation projects. Water conservancy projects that can serve multiple goals such as flood control, water supply, irrigation, and power generation are called comprehensive water conservancy projects. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, ferry canals, rafts, and fishways to achieve their goals. Compared with other projects, water conservancy projects have the following characteristics: ① Wide impact. Water conservancy project planning is an integral part of river basin planning or regional water conservancy planning. ② Water conservancy projects are generally large in scale, require large investments, are technically complex, and have a long construction period. Water conservancy projects generally involve water level monitoring of rivers, lakes or groundwater. Water level information is closely related to human social life. The planning, design, construction and management of water conservancy projects require water level information. The construction of bridges, ports, waterways, drainage and other projects also requires water level information. In flood control and drought relief, water level information is even more important. It is the basis for hydrological forecasts and hydrological intelligence. Generally, water level meters or water level monitoring devices are used to monitor water levels.

[0003] Existing liquid level monitoring devices usually use an extension rope or other flexible materials to connect the sensor and the monitoring point to monitor the contact with the water surface. Although this method can be adapted to waters of different depths, it also has some limitations and problems.

[0004] First, when the extension cord is immersed in water, it may be affected by the water flow and deflect or swing, especially in a turbulent water environment. This swing will not only lead to unstable measurements, but also may make the data obtained inaccurate. In addition, if the water level monitoring device needs to be extended to the bottom of the water to measure the water depth, placing the sensor directly on the bottom of the water may cause it to be subjected to stronger physical impacts, such as water scouring, sediment movement, etc., all of which may lead to deviations in the measurement results.

[0005] On the other hand, if a rigid straight rod is used to replace the extension rope for measurement, although it can reduce the impact of water flow on the sensor to a certain extent and improve stability, such a design is often limited by length and may not be able to achieve effective monitoring in deeper waters. At the same time, the rigid straight rod is relatively inconvenient in operation, especially when the monitoring position needs to be adjusted frequently, which will increase the workload and complexity of the operation.

[0032] Working principle:

[0033] When the device is in use, the fixing plate 28 is fixed to a surface such as a dam, a wall, or a column to fix the device in a working position, and the sliding drum 4 is further driven to rotate by the servo motor 11, and the rope drum 7 mounted thereon is driven to rotate, so that the extension rope 9 wound thereon is extended from the positioning tube 2, and the liquid level sensor 10 provided at the end of the extension rope 9 is extended into the water flow for monitoring. During the rotation process, the rope drum 7 slides on the sliding drum 4 due to the movement of the extension rope 9, so that the extension rope 9 is always aligned with the position of the positioning tube 2, and the extension rope 9 and the liquid level sensor 10 connected to the end thereof enter the monitored water area. If the water flow is turbulent, it will be affected and deviated, and the deviation direction is observed by the monitoring camera 30, and the servo motor 25 is further adjusted and rotated to drive the gear 26 provided at its output end to rotate, and then drive the gear ring 20 meshing with the gear 26 to rotate. The rotation drives the turntable 1 to rotate, and then drives the extension rope 9 to rotate, so that the vertical chain composed of multiple vertical chain links connected end to end on the surface of the extension rope 9 changes direction from water flow impact to a vertical state, specifically, the limiting plate 14 provided on the upper front side of the chain body 13 of the vertical chain link enters the limiting groove 15 provided on the lower front side of the chain body 13 of the previous vertical chain link, so that the multiple vertical chain links remain in a vertical state, so that the extension rope 9 always remains in a vertical state, which improves the measurement accuracy of the liquid level sensor 10 and reduces the influence of the water flow on it. The approximate direction of the water flow can also be determined by monitoring the angle of the turntable 1 after rotation and adjustment, so as to provide more information for liquid level information monitoring. After the work is completed, the extension rope 9 is recovered by rotating the rope drum 7. Since the vertical chain can be bent, it can be wound around the rope drum 7, so that it can increase its length and reduce the footprint, thereby improving the application range and flexibility of the device.
