Description

Technical Field

[0001] The invention relates to the technical field of dam burst test, and in particular to a dam burst test monitoring system. Background Art

[0002] Most existing dam breach test monitoring systems use general hydraulic water level gauges, propeller flow meters, ADV flow meters and other instruments to detect the water level and flow velocity of the breach. They measure the change process of the breach by drawing a grid on the dam body in advance and then manually reading the breach size through video processing.

[0003] The water flow conditions of dam breach are complex, the water level drop rate and drop amplitude are large, the water flow has a high sand content, and floating objects are common. The detection equipment in the existing technology, such as hydraulic water level gauges, propeller flow meters, and ADV flow meters, cannot measure accurately. At the same time, the image distortion of the camera will cause a large error in the reading, affecting the accuracy of the measurement of the breach change process. Therefore, the present invention proposes a dam breach test monitoring system to solve the above problems. Summary of the invention

[0004] Based on the background technology, most of the existing dam burst test monitoring systems use general hydraulic water level gauges, propeller flow meters, ADV flow meters and other instruments to detect the water level and flow velocity of the breach, and measure the change process of the breach by drawing a grid on the dam body in advance and manually reading the breach size through video processing in the later stage. The dam burst water flow conditions are complex, the water level drop rate and drop amplitude are large, the water flow has a high sand content, and floating objects are also common. The detection equipment in the prior art such as hydraulic water level gauges, propeller flow meters, ADV flow meters cannot measure accurately. At the same time, the image distortion of the camera will cause a large error in the reading, affecting the accuracy of the measurement of the breach change process. The present invention proposes a dam burst test monitoring system.

When holding the handle 23 and pulling the grip rod 32 to move to the left, the reset spring 33 will be stretched first, and then the two sliding blocks 31 will be driven to move to the left. The top and bottom of the grip rod 32 can be used by the two sliding blocks 31 to open the distance between the two sliding rods 30, so that the two sliding rods 30 can be moved away from each other. The two sliding rods 30 can drive the two fitting rods 29 to move away from each other, so as to push the two positioning frames 26 to disengage from the two matching blocks 28, to unlock the matching blocks 28 and the mounting plate 22, and then the mounting plate 22 can be disassembled. The mounting plate 22 brings the filter screen 20 out, and the filter screen 20 can be directly pulled out on the mounting plate 22 and disengaged from the connecting block 21, so that the filter screen 20 can be disassembled and replaced conveniently.

[0064] Working principle: The acquisition and control terminal 6 automatically adjusts the flow measured by the electromagnetic flowmeter 4. When the required inflow is small, the opening of the electric control valve 5 is controlled to adjust the flow size of the pipeline 17 to change the inflow. When the required inflow is large, the inflow is controlled by the electric lifting valve of the horizontal water tower 2. The shell 18 can also filter the water to avoid system blockage and unusability. There are ten ultrasonic water level and flowmeters 7, which are distributed at intervals.

The surface flow field meter 10 measures the surface flow velocity distribution of the downstream river channel 11, revealing the formation and development mechanism of the breach and the evolution mechanism of the downstream river channel 11. The industrial camera 12 has no image distortion. The four industrial cameras 12 record the high-fidelity breach process of the barrier dam 9 from multiple angles and in all directions.

The real-time analysis control terminal 14 can adjust the industrial camera 12 and the high-frequency terrain sensor 13 according to the actual situation, and store and display various data in the breach process in real time. The walking topograph 15 and the stationary topograph 16 are used to monitor the terrain changes of the downstream river channel 11. In the early stage of the breach, a large amount of silt is deposited at the foot of the dam. As the breach flow increases, it is continuously transported and deposited downstream. The terrain scouring and silting changes dramatically during the whole process. The terrain of the downstream river channel 11 changes significantly. The shell 18 filters water for a long time. When the filter screen 20 is blocked, it is only necessary to hold the handle 23 on the left side of the shell 18 and pull the grip rod 32 to move to the left, firstly stretching the reset spring 33 and then driving the two sliding blocks 31 to move to the left, and the top and bottom of the grip rod 32 can use the two sliding blocks 31 to open the distance between the two sliding rods 30, so that the two sliding rods 30 can move away from each other, and the two sliding rods 30 can drive the two fitting rods 29 to move away from each other, so as to push the two positioning frames 26 to disengage from the two matching blocks 28, so as to unlock the matching blocks 28 and the mounting plate 22, and then the mounting plate 22 can be disassembled, and the mounting plate 22 brings out the filter screen 20, and the filter screen 20 can be directly pulled out on the mounting plate 22, and the filter screen 20 can be directly pulled out on the mounting plate 22. When the connecting block 21 is detached, the filter 20 can be disassembled, and then a new filter 20 can be inserted into the connecting block 21 and installed on the mounting plate 22. Then the mounting plate 22 is docked with the left side of the shell 18, and the matching block 28 on the mounting plate 22 automatically engages with the positioning frame 26, and the mounting plate 22 brings the filter 20 into the inner side of the shell 18. After the positioning frame 26 engages with the matching block 28, the positioning frame 26 can prevent the matching block 28 and the mounting plate 22 from detaching from the shell 18, and the mounting plate 22 can be installed on the left side of the shell 18, and the filter 20 is installed on the inner side of the shell 18, so that the filter 20 on the inner side of the shell 18 can filter the water entering the shell 18, filter out impurities, and avoid system blockage.
