Description

Technical Field

[0001] The present invention relates to the technical field of monitoring devices, and more specifically, to an intelligent sediment flow real-time monitoring device for river and water hydrological detection. Background Art

[0002] A river sediment flow monitoring device is a device specifically used for open water source exploration and real-time monitoring of sediment flow and related parameters in rivers. It can obtain the sediment flow and related parameters in rivers in real time, help to understand hydrological changes in a timely manner, evaluate the impact on the ecological environment, discover potential ecological problems in a timely manner, store the monitoring data locally or in the cloud for subsequent analysis and historical data query. Such a device is of great significance for fields such as water resource management, environmental protection, and flood control and disaster resistance. It is commonly used for sediment monitoring in water conservancy projects such as reservoirs, rivers, and lakes, and provides basic data for scientific research in fields such as hydrology and water resources.

[0003] A Chinese patent with the publication number CN108469257B discloses an on-line suspended sediment measurement device, including a submersible pump and a heat preservation box. There is a water storage tank inside the heat preservation box, achieving the automation of suspended sediment information collection, the networking of transmission, and the scientific analysis, effectively improving the timeliness and reliability of suspended sediment information collection, transmission, processing, and analysis.

[0004] A Chinese patent with the publication number CN118189911B discloses a river sediment content monitoring system, including: a data collection module for detecting parameters at various positions of the river; by setting a collection module for collecting various parameters of the river, it is ensured that the real-time state of the river can be collected, and then the corresponding parameter information is fed back to the data processing module to process the data and conduct a risk assessment on various positions of the river, realizing the monitoring of the risk of natural disasters occurring in the river.

[0005] The above-mentioned and similar prior arts can, to a certain extent, achieve the monitoring of river sediment flow. However, the common method of the prior art is to first take samples of river water and then conduct sediment detection on the sampled river water. Although this method is widely used in sediment monitoring, it takes a certain amount of time for laboratory analysis after sampling, and real-time monitoring cannot be achieved, resulting in data lag. In the case of rapid changes in sediment flow, the sampling method cannot reflect the current sediment situation in a timely manner. Moreover, in order to improve the accuracy of data, frequent sampling will increase the labor and material costs, making it difficult to conduct periodic real-time monitoring of river sediment flow.

[0006] Therefore, the present invention provides an intelligent sediment flow real-time monitoring device for river and water hydrological detection that can continuously conduct periodic monitoring of sediment flow in river water. Summary of the Invention

DETAILED DESCRIPTION

[0022] In order to make the technical means, technical features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] Example: Figures 1-11 As shown, an intelligent real-time monitoring device for sediment flow for river hydrological detection described in the present invention comprises a fixing frame 1, a monitoring tube 2 is fixedly installed at the bottom of the fixing frame 1, a right sealing plate 6 is installed on one side of the monitoring tube 2 through a plurality of bolts, a rotating shaft 8 is rotatably installed inside the right sealing plate 6 through a bearing, a right water wheel 9 is fixedly installed on the outer side of the rotating shaft 8, and the right water wheel 9 is located on the side of the right sealing plate 6 away from the monitoring tube 2, a left sealing plate 14 is installed on the other side of the monitoring tube 2 through a plurality of bolts, and a left sealing plate 14 is fixed on the inner side of the monitoring tube 2. A partition plate 3 is installed, two water inlets 4 are penetrated on one side of the monitoring tube 2, two water outlets 5 are penetrated on the other side of the monitoring tube 2, and the two water inlets 4 and the two water outlets 5 are respectively located on both sides of the partition plate 3, a right protective cover 7 is fixedly installed on the side of the right sealing plate 6 away from the monitoring tube 2, the right water wheel 9 is located on the inner side of the right protective cover 7, a left protective cover 23 is fixedly installed on the side of the left sealing plate 14 away from the monitoring tube 2, and the left protective cover 23 is lower than the right protective cover 7, and an air cavity 25 is formed inside the monitoring tube 2 after the monitoring tube 2 sinks into the water.

[0024] Specifically, the fixing frame 1 can provide fixed support for the monitoring cylinder 2. The monitoring cylinder 2 can provide a threaded through-space for the right sealing plate 6 and the left sealing plate 14. The right sealing plate 6 and the left sealing plate 14 can provide a sealing effect for the monitoring cylinder 2. The right sealing plate 6 can provide stable support for the right protective cover 7. The right protective cover 7, the right sealing plate 6, the partition plate 3, and the left sealing plate 14 can provide bearing rotation support for the rotating shaft 8. The partition plate 3 can divide the monitoring cylinder 2 into two independent spaces, enabling the two collecting mechanisms 10 to work independently. The monitoring cylinder 2 can provide a through-space for the water inlet 4 and the water outlet 5. The water inlet 4 is aligned with the horizontally-positioned mesh cylinder 101, allowing flowing water to enter the inside of the mesh cylinder 101 through the water inlet 4. The bottom wall of the water outlet 5 is lower, facilitating the overflow of the sediment flushed out from the mesh cylinder 101 through the water outlet 5. The height of the left protective cover 23 is lower than that of the right protective cover 7, causing the impact of the flowing water on the left water wheel 242 to be greater than that on the right water wheel 9. As a result, the rotational speed of the left water wheel 242 is greater than that of the right water wheel 9. This is convenient for the subsequent process where the right water wheel 9 drives the rotating shaft 8 to rotate 90°. During this process, the left water wheel 242 can quickly move away from the left sealing plate 14 first, enabling the contact plate 18 to quickly reset and limit the contact rod 12.

[0025] In this embodiment, two collecting mechanisms 10 are fixedly installed on the outer side of the rotating shaft 8. The collecting mechanisms 10 are assembled to drive the two mesh cylinders 101 to rotate through the rotating shaft 8, enabling the horizontally-positioned mesh cylinder 101 to cooperate with the filter net 104 for sediment collection, and enabling the vertically-positioned mesh cylinder 101 to cooperate with the filter net 104 to move the collected sediment out to the air chamber 25 for detection. The collecting mechanism 10 includes a mesh cylinder 101. A filter net 104 is arranged inside the mesh cylinder 101. The mesh cylinders 101 of the two collecting mechanisms 10 are perpendicular to each other. The collecting mechanism 10 further includes fixing rings 102. The two fixing rings 102 are fixedly installed inside the mesh cylinder 101. Annular pressure sensors 103 are fixedly installed on the sides of the two fixing rings 102 away from each other. The sides of the two pressure sensors 103 away from each other are fixedly connected to the filter net 104.

[0026] Specifically, the net tube 101 can provide a stable support for the fixing ring 102, and the fixing ring 102 can provide a stable support for the pressure sensor 103 and the filter 104. The net tube 101 and the filter 104 can facilitate air to pass through at will, and prevent the net tube 101 from taking away the air in the air cavity 25 when rotating. The pressure sensor 103 can transmit the pressure change to the processor, and the processor transmits the pressure change to the data processing center through a wireless signal for recording and intuitively displaying it through a display device, so that the staff can remotely grasp the real-time The pressure of the pressure sensor 103 changes. The pressure sensor 103 is first continuously impacted by the river water during the filtering and collecting process, and as the filtering proceeds, the force on the pressure sensor 103 gradually increases. When the net tube 101 rotates 90° to allow river water to leak, the force on the pressure sensor 103 will gradually decrease to a stable value. The pressure reading at a stable state is the weight of the sediment. When the net tube 101 rotates 90° again, the force on the pressure sensor 103 will be zero. Therefore, the sediment flow rate of the river water can be judged by the pressure of the pressure sensor 103 gradually decreasing to a stable value.

[0027] In this embodiment, the rotating shaft 8 passes through the interior of the partition plate 3 and the left sealing plate 14 through the bearing, and there are two mutually perpendicular flat plate shapes in the middle position of the rotating shaft 8, and the flat plate shape positions of the rotating shaft 8 respectively pass through the interiors of the two net cylinders 101, and the central axis of the net cylinder 101 is parallel to the flat plate shape part of the rotating shaft 8. A turntable 11 is fixedly installed at the end of the rotating shaft 8 away from the right water wheel 9, and the turntable 11 is located on the side of the left sealing plate 14 away from the monitoring cylinder 2, four abutment rods 12 are fixedly installed on the outer side of the turntable 11, and a rotating groove 13 is opened on the side of the turntable 11 away from the left sealing plate 14.

[0028] Specifically, the flat shape of the rotating shaft 8 can provide stable support for the mesh cylinder 101. When the mesh cylinder 101 is filtering and collecting, the flat shape of the rotating shaft 8 can be parallel to the flow direction of the water, thereby reducing the obstruction to the water flow, allowing the water to flow from the position of the water inlet 4 to the position of the water outlet 5 in the mesh cylinder 101, flushing the mud and sand detected last time, forming automatic cleaning. The rotating shaft 8 can provide stable support for the turntable 11, and the turntable 11 can provide stable support for the resistance rod 12. The working state of the rotating shaft 8 is determined by limiting or releasing the resistance rod 12. The turntable 11 can provide an opening space for the rotating groove 13, and the rotating groove 13 provides rotational support for one end of the bidirectional screw through a bearing.

[0029] In this embodiment, two limiting grooves 15 are provided on the side of the left sealing plate 14 away from the monitoring tube 2, and the two limiting grooves 15 are symmetrical with respect to the center of the rotating shaft 8, a guide rod 16 is fixedly installed on the inner side of the limiting groove 15, one end of a spring 17 is fixedly installed on the inner wall of the limiting groove 15 away from the rotating shaft 8, a contact plate 18 is fixedly installed on the other end of the spring 17, and the contact plate 18 is slidably installed on the outer side of the guide rod 16, an inclined surface is provided on the side where the two contact plates 18 are close to each other, the contact plate 18 is slidably installed on the inner side of the limiting groove 15, and the contact plate 18 is in contact with the contact rod 12, and the left sealing plate 14 is far away from the monitoring tube 2. A plurality of limit rods 19 are fixedly installed on the side away from the monitoring tube 2, and one end of a plurality of springs 20 are fixedly installed on the side of the left sealing plate 14 away from the monitoring tube 2, and the spring 20 is located on the outside of the limit rod 19, and a pressure plate 21 is fixedly installed on the other end of the spring 20, and the pressure plate 21 is slidably installed on the outside of the limit rod 19, the pressure plate 21 is located on the outside of the reciprocating screw rod 241, and two push plates 22 are fixedly installed on the side of the pressure plate 21 close to the left sealing plate 14, the surfaces of the two push plates 22 are provided with arc surfaces, and the arc surfaces of the push plates 22 are aligned with the inclined surfaces of the contact plate 18, and the push plates 22 are in contact and cooperate with the contact plate 18.

[0030] Specifically, the left sealing plate 14 can provide a space for the limiting groove 15, the limiting groove 15 can provide a placement space for the guide rod 16, the spring 17 and the contact plate 18, the guide rod 16 and the limiting groove 15 can provide a guiding effect for the contact plate 18, the spring 17 can provide a reset driving force for the contact plate 18, and the contact plate 18 can provide a limiting effect for the contact rod 12 when it contacts the contact rod 12, thereby providing a limiting effect for the rotating shaft 8, and the left sealing plate 14 can provide a stable support for the limiting rod 19, and the limiting The positioning plate can provide limiting and guiding functions for the pressure plate 21, the spring 20 can provide a reset function for the pressure plate 21, the pressure plate 21 can provide a stable support for the push plate 22, and the arc surface of the push plate 22 can interfere with the inclined surface of the contact plate 18, so that when the pressure plate 21 drives the push plate 22 to move toward the left sealing plate 14, the push plate 22 uses the interference with the contact plate 18 to drive the two contact plates 18 away from each other, so that the two contact plates 18 no longer contact with the interference rod 12, thereby releasing the limitation on the rotating shaft 8.

[0031] In this embodiment, a reciprocating mechanism 24 is provided on the side of the left sealing plate 14 away from the monitoring cylinder 2. The reciprocating mechanism 24 is assembled to drive the extrusion ring 244 to move left and right through the threaded cooperation between the reciprocating lead screw 241 and the thread teeth 243, so that the extrusion ring 244 intermittently extrudes the pressure plate 21. The pressure plate 21 intermittently pushes the contact plate 18 to separate from the contact rod 12, thereby intermittently rotating the collection mechanism 10 for collection and detection. The reciprocating mechanism 24 includes a reciprocating lead screw 241. A left water wheel 242 is arranged on the outer side of the reciprocating lead screw 241 through the thread teeth 243. An extrusion ring 244 is fixedly installed on one side of the left water wheel 242. One end of the reciprocating lead screw 241 is fixedly installed on the inner wall of one side of the left cover 23. The other end of the reciprocating lead screw 241 is embedded in the inner side of the rotating groove 13 through a bearing. The thread teeth 243 are in threaded cooperation with the reciprocating lead screw 241 to rotate left and right. A plurality of rotatable tapered rollers 245 are embedded and installed on the side of the extrusion ring 244 close to the left cover 23.

[0032] Specifically, the left cover 23 can provide a stable support for the reciprocating lead screw 241. The left water wheel 242 can provide a stable support for the thread teeth 243. The thread teeth 243 can have a threaded effect with the reciprocating lead screw 241. Thus, when the left water wheel 242 rotates in the same direction, it can drive the thread teeth 243 to have a threaded effect with the reciprocating lead screw 241, causing the left water wheel 242 to move left and right during rotation. The left water wheel 242 can provide a stable support for the extrusion ring 244. The extrusion ring 244 can provide a rotating space for the tapered rollers 245. When the extrusion ring 244 moves to the right to extrude the pressure plate 21, the tapered rollers 245 in the extrusion ring 244 contact the pressure plate 21, causing the extrusion ring 244 to extrude the pressure plate 21 to the right through the tapered rollers 245. The tapered rollers 245 rotate during the extrusion process to reduce the friction between the extrusion ring 244 and the pressure plate 21.

[0033] Working principle: The staff first fixes and installs the device in the river water through the fixing frame 1, making the water inlet 4 face the direction of the river water flow. The air inside the monitoring cylinder 2 has no time to escape and stays in the monitoring cylinder 2 to form an air cavity 25, as Figure 11 shown; At this time, the net cylinder 101 on the left is in a horizontal state, and the river water drives the silt to enter the net cylinder 101 on the left through the water inlet 4, and the silt is filtered by the filter 104 in the left net cylinder 101. At the same time, the river water impacts the left water wheel 242, causing the left water wheel 242 to rotate under the impact of the river water, and the left water wheel 242 drives the thread teeth 243 to rotate, so that the thread teeth 243 use the thread action with the reciprocating screw rod 241 to drive the left water wheel 242 to move to the right, and the left water wheel 242 drives the extrusion ring 244 to rotate and move to the right. After a period of time, the conical roller 245 in the extrusion ring 244 contacts the pressure plate 21, so that the extrusion ring 2 The pressing plate 21 is pressed to the right by the tapered roller 245. The tapered roller 245 rotates during the pressing process to reduce the friction between the pressing ring 244 and the pressing plate 21. The pressing plate 21 is pressed to move to the right, so that the pressing plate 21 moves to the right under the guidance of the limiting rod 19, and the pressing plate 21 compresses the spring 20 to be compressed and deformed. At the same time, the pressing plate 21 drives the push plate 22 to contact the contact plate 18, so that the push plate 22 uses its own arc surface and the inclined surface of the contact plate 18 to drive the two contact plates 18 to move away from each other. The contact plate 18 moves along the outer side of the guide rod 16 and the inner side of the limiting groove 15, and compresses the spring 17 to be compressed and deformed. When the abutment plate 18 moves to separate from the abutment rod 12, the shaft 8 loses its limit and is unlocked, and then the right water wheel 9 drives the shaft 8 to rotate under the impact of river water. During the rotation of the shaft 8, the left water wheel 242 drives the threaded teeth 243 to move to the rightmost end of the thread of the reciprocating screw 241, and under the action of the thread of the reciprocating screw 241, the left water wheel 242 moves to the left side to return. The rotation direction of the left water wheel 242 remains unchanged, but the moving direction changes. When the left water wheel 242 moves to the left side, the pressure plate 21 moves away from the left sealing plate 14 under the elastic force of the spring 20, so that the push plate 22 no longer presses the abutment plate 18, so that the abutment plate 18 is reset under the elastic force of the spring 17; After the abutment plate 18 is reset, the shaft 8 rotates 90° under the action of the right water wheel 9, so that the shaft 8 drives the turntable 11 to rotate 90°, so that the abutment rod 12 near the front rotates to the top and contacts the abutment plate 18, and the shaft 8 is limited by the abutment plate 18 and the abutment rod 12 again. The right water wheel 9 is continuously impacted by the river water, and although it does not rotate, it continuously provides a rotational driving force for the shaft 8, so that the limiting action of the abutment rod 12 and the abutment plate 18 continues. After the rotating shaft 8 rotates 90°, the two mesh cylinders 101 are driven by the rotating shaft 8 to rotate 90°. The mesh cylinder 101 on the left for filtering sediment rotates to a vertical state, and the filter net 104 collecting sediment is rotated to the inside of the air chamber 25, exposing the filter net 104 and the sediment to the air, allowing the water in the sediment to gradually leak out. After the mesh cylinder 101 on the right rotates 90°, it will continue to filter and collect sediment from the river water. The two mesh cylinders 101 respectively perform the processes of river water leakage and filtration collection. During this process, the left water wheel 242 moves reciprocally under the impact of the river water and the action of the reciprocating lead screw 241, providing sufficient time for the river water leakage and filtration processes. When one reciprocating process of the left water wheel 242 ends, the two mesh cylinders 101 will rotate 90° again. At this time, the filter net 104 for river water leakage rotates to a position close to the water outlet 5, and the river water passing through the mesh cylinder 101 will wash the sediment on the surface of the filter net 104, washing away the sediment after the river water leakage. The filter net 104 at the other end of the mesh cylinder 101 performs filtration collection again; During this process, the pressure sensor 103 is continuously impacted by the river water during the filtration collection process. As the filtration progresses, the force on the pressure sensor 103 gradually increases. When the mesh cylinder 101 rotates 90° for river water leakage, the force on the pressure sensor 103 will gradually decrease to a stable state. When the mesh cylinder 101 rotates 90° again, the force on the pressure sensor 103 will be zero. Therefore, the sediment flow rate of the river water can be judged by the value when the pressure of the pressure sensor 103 gradually decreases to a stable state.
