Description
Technical Field
The invention relates to an automatic device for measuring the sand content of a measuring weir, belonging to the technical field of measurement.
Background
With the general development of hydraulic engineering in China in recent years, the number of dams is increased, the dams age structurally over time under the long-term action of various loads and the influence of severe environmental factors such as flood, earthquake and the like, and the dams are influenced by surrounding geological structures, so that the operation risk is increased, certain potential safety hazards exist in dam buildings, and the safety problem of the dams is more and more prominent;
after the reservoir is built, the working states of a dam, a bedrock, a dam abutment, a bank slope and an underground building are greatly influenced due to the change of water level foundation conditions. Particularly, after the dam stores water, hydraulic load is generated on the dam, and seepage is generated on a dam body and a dam foundation under the action of upstream and downstream water level differences. Once an accident occurs, immeasurable losses will be caused to the downstream and surrounding areas. The measuring weir is a structure for monitoring the water flowing through the dam body and the dam foundation to observe and measure. However, the water measuring weir cannot measure the sand content of the water flow, and cannot comprehensively reflect the health conditions of the dam body and the dam foundation. At present, the sand content of water flow is mostly measured by manually collecting the sand content in a container on site and drying the sand content to obtain the sand content, the sand content of the water flow in a measuring weir cannot be directly measured, and a large amount of time cost and manpower are consumed for manual on-site observation and detection, so that the working efficiency is low;
in order to ensure the safe operation of the dam, the safety detection of the dam needs to be strengthened, the operation condition of the dam needs to be mastered in time, the safety problem of the dam is found in time, and the safety problem is processed in time. The method lays a good foundation for long-term safe and stable operation of the dam, and plays an important role of the dam better. Based on the explanation, the automatic device for measuring the sand content of the water measuring weir is adopted, so that the regular automatic measurement of the sand content of the water measuring weir can be realized, the manpower and material resources are greatly saved, and the measurement efficiency is improved.
Disclosure of Invention
The invention aims to design an automatic device for measuring the sand content of the water measuring weir, which overcomes the defect that the traditional water measuring weir cannot measure the sand content of water flow, provides new reference data for dam body health detection, and reflects the running condition of a dam in time to enable the dam to play a better role;
an automatic device for measuring the sand content of a water measuring weir comprises the following technical scheme: the device comprises a water-sand separation module, an image acquisition module and a data processing module. The water-sand separation module comprises an automatic water pump and a water-sand separator. The water-sand separator comprises a water inlet, a water outlet, volume scale marks and an electric plug; the automatic water pump pumps water in the water measuring weir into a water inlet of the water-sand separator, and the water overflows from the water outlet, and after a period of time, sand is precipitated at the bottom of the water-sand separator; the camera is arranged on one side, right opposite to the scale marks of the water-sand separator, fixedly supported by the automatic lifting rod and used for collecting images of collected sand; the data processing module is used for receiving the image shot by the camera, reading the sand content and calculating the sand content of the measuring weir through an algorithm preset in the network server;
the invention has the beneficial effects that: because the traditional measuring weir can only calculate the runoff, the information of the sand content cannot be obtained, and the health condition of the dam body cannot be comprehensively reflected. And the manual on-site measurement of the sand content can cost a lot of time and manpower resources, frequent and timely measurement cannot be performed, and inaccurate measurement results can bring wrong judgment to dam body detection. Aiming at the problems, the automatic device for measuring the sand content of the water measuring weir provided by the invention effectively overcomes the defect that the manual field measurement of the sand content is easily influenced by factors such as weather and environment, can realize the remote automatic measurement of the sand content of the water measuring weir, and has higher accuracy.
