2. the air exhaust structure is provided with a plurality of openings, so that the silt at each position can be started and kept suspended for a long time, and the silt is convenient to transport;
3. the turbidity meter monitors the sand content in the river channel in real time and transmits the sand content to the control device in real time, and the control device remotely controls exhaust, so that the sedimentation of the river channel can be avoided in time;
4. need to cut off the upper and lower trip during the normal desilting of river course, the utility model discloses a system's desilting need not cut off, the material resources of using manpower sparingly.
Drawings
Fig. 1 is a schematic structural view of a pneumatic silt prevention system of a culvert shown in embodiment 1.
Fig. 2 is a schematic structural view of a pneumatic silt prevention system for a hidden culvert with a very narrow space in embodiment 2.
In the figure: 1. the air exhaust structure comprises 2 parts of a pressure weight, 3 parts of a connecting pipeline, 4 parts of an air compressor, 5 parts of a sealing gasket, 6 parts of a turbidity meter, 7 parts of a control device and 8 parts of a hidden culvert.
Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings:
example 1
The pneumatic silt prevention system of dark culvert shown in figure 1 comprises an air exhaust structure 1, a ballast 2, a connecting pipeline 3, an air compressor 4, a sealing gasket 5, a turbidity meter 6 and a control device 7.
The gas exhaust structure 1 is a net structure formed by pipelines with holes on the surface; control device 7 is connected with turbidity appearance 6, air compressor machine 4 respectively, acquires the turbidity detected signal that turbidity appearance 6 gathered to open and stop based on turbidity detected signal control air compressor machine 4. The air compressor 4 is connected with the air exhaust structure 1 and used for supplying air to the air exhaust structure 1. The two sides of the air exhaust structure 1 are provided with weights 2.
The system can be integrally placed at the bottom of the dark culvert after being installed on the shore, and the air compressor 4, the turbidity meter 6 and the control device 7 are ensured to be on the same side as much as possible, so that the installation is convenient. The air exhaust structure 1 needs to be tightly attached to the wall surface and the bottom of the culvert 8, wherein an opening is not arranged on one side close to the wall surface, and the specific net-shaped arrangement can be determined according to the length and the width of the bottom of each culvert 8. The ballast weights 2 are arranged on the left side and the right side of the pipe network of the air exhaust structure 1, generally adopt a concrete structure, have good durability and heavy weight, and are not easy to be washed away by water flow. Two ends of the ballast 2 on one side of the gas exhaust structure 1 are required to be provided with small holes, so that the connecting pipeline 3 is convenient to arrange and can also play a role in fixing the pipeline. The connecting pipeline 3 penetrates through the ballast 2 to be communicated with the air exhaust structure 1 and the air compressor 4 and is used for conveying high-pressure air. Air compressor machine 4 arranges in dark culvert side, and highly should be above the highest water level, and 4 ventholes of air compressor machine utilize sealed 5 sealedly with connecting tube 3 junction, avoid rivers to flow into. The turbidity meter 6 is connected with the control device 7 through the connecting pipeline 3, and an electrically connected line is laid in the connecting pipeline 3; turbidity appearance 6 arranges in dark 8 side intermediate positions of culvert, remains throughout below the minimum water level, and real-time supervision river course turbidity and reflection give controlling means 7, and controlling means 7 is equipped with certain turbidity alarm value and safe value according to each river course state, and be high turbidity when the turbidity is greater than 100NTU, be less than 10NTU and be low turbidity, so adopt 100NTU as turbidity alarm value, 10NTU as turbidity safe value. When the turbidity exceeds the alarm value, the air compressor 4 is controlled to be started to exhaust, and when the turbidity reaches a safety value, the exhaust is stopped, so that the sediment deposition is not generated in the hidden culvert.
Example 2
This embodiment provides the pneumatic silt-preventing system of dark culvert to the very narrow and small dark culvert in space.
As shown in figure 2, in the dark culvert that the space is very narrow and small, be difficult to arrange too much equipment in dark culvert 8, only place gas drainage structure 1, ballast 2 and turbidity meter 6, air compressor machine 4 and controlling means 6 hug closely the dark culvert wall with connecting tube 3 and extend to the bank, arrange the height and need be above the highest water level.
The unexplained parts related to the present invention are the same as or implemented by using the prior art.
