Embodiment 1

[0031] refer to Figure 1-5 , an assessment device for sea level rise based on hydrodynamics, comprising a plurality of monitoring buoyant tanks 1, characterized in that a plurality of monitoring buoyant tanks 1 are slidingly installed with moving plates 2, and the bottoms of the plurality of moving plates 2 are all fixed A controller is installed, a plurality of controllers are connected through a network, and a fixing hole is provided on the bottom inner wall of the monitoring buoyancy tank 1, and a moving column 3 is slidably installed in the fixing hole, and the top of the moving column 3 is fixedly installed on the surface of the moving plate 2, The bottom of the moving column 3 is provided with a rotating groove 4, and a rotating seat 5 is installed in the rotating groove 4, and a controller 8 is fixedly installed on the bottom of the rotating seat 5, and a plurality of teeth are fixedly connected on the rotating seat 5. There is a groove on the inner wall, and a steppin...

Embodiment 2

[0040] A method for assessing sea level rise based on hydrodynamic forces, comprising the following steps:

[0041] S1: By connecting multiple monitoring buoys 1 to the same network controller, mutual communication and data transmission can be realized. Multiple monitoring buoys 1 can monitor sea level height and water flow direction at the same time. The battery is a stepping motor 6, The sonar probe 9, the flow meter 12 and the servo motor 16 provide power, and when the tide rises, the monitoring buoy tank 1 in the upstream of the water area drives the second sprocket 17 to rotate through the servo motor 16;

[0042] S2: The second sprocket 17 drives the chain 15 to rotate, the chain 15 drives the first sprocket 14 to rotate, the first sprocket 14 drives the corresponding screw rod 13 to rotate, the screw rod 13 drives the moving plate 2 to move, and the moving plate 2 drives the moving column 3 moves upward, the moving column 3 drives the controller 8 to move upward, the co...

Abstract

The invention belongs to the field of sea level evaluation and especially relates to a device and method for evaluating sea level rise based on hydrodynamic force. For the problem that an existing evaluation device for sea level rise based on hydrodynamic force has low practicability and the evaluation from different tide level, flow rate and flow direction conditions is difficult, the invention proposes a following scheme, the device of the invention comprises a plurality of monitoring floating boxes, moving plates are installed in the multiple monitoring floating boxes in a sliding mode, controllers are fixedly installed at the bottoms of the multiple moving plates and are connected through a network, fixed holes are formed in inner walls of tops of the monitoring floating boxes, movingcolumns are slidably installed in the fixed holes, top ends of the moving columns are fixedly installed on the surfaces of the moving plates, and rotating grooves are formed in the bottoms of the moving columns. The evaluation device of the invention has the advantages of reasonable structure, convenient operation and high practicability, the multiple monitoring floating boxes can collect data from different tide levels, flow rates and flow directions, and the evaluation result is accurate.

Description

technical field [0001] The invention relates to the technical field of sea level assessment, in particular to a device and method for assessing sea level rise based on hydrodynamic forces. Background technique [0002] Climate change has caused phenomena such as rising temperatures on the earth's surface, melting glaciers, and rising sea levels, which have caused enormous damage to the natural environment on which humans depend. Under the influence of climate change, extremes such as droughts, floods, high-temperature heat waves, and typhoons Climate events are frequent and concurrent. China is one of the developing countries most severely affected by climate change, especially the most ecologically vulnerable coastal areas in my country, which are facing the long-term impact and threat of sea level rise. According to the United Nations Intergovernmental In 2013, the Panel on Climate Change (IPCC) assessed sea level changes from 1901 to 2010 and concluded that the average grow...
