Description

Technical Field

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

[0002] The river sediment flow monitoring device is a device specially used for open-air water source surveys and real-time monitoring of sediment flow and related parameters in rivers. It can obtain sediment flow and related parameters in rivers in real time, help to timely understand hydrological changes, evaluate the impact on the ecological environment, and promptly discover potential ecological problems. The monitoring data is stored locally or in the cloud for subsequent analysis and historical data query. This device is of great significance to water resource management, environmental protection, flood control and disaster relief, and is often used for sediment monitoring in water conservancy projects such as reservoirs, rivers, and lakes, providing basic data for scientific research in the fields of hydrology and water resources.

[0003] Chinese patent publication number CN108469257B discloses an online suspended sediment measurement device, including a submersible pump and an insulated box with a water storage tank inside. This device automates the collection of suspended sediment information, enables networked transmission, and scientific analysis, effectively improving the timeliness and reliability of suspended sediment information collection, transmission, processing, and analysis.

[0004] Chinese patent publication number CN118189911B discloses a river sediment content monitoring system, including a data acquisition module for detecting parameters at various river locations. This invention ensures that the real-time status of the river can be collected by providing an acquisition module for collecting various river parameters. The corresponding parameter information is then fed back to the data processing module, which processes the data and conducts risk assessments at various river locations, thereby monitoring the risk of natural disasters in the river.

[0005] The above-mentioned and similar existing technologies can, to a certain extent, realize the monitoring of river water sediment flow. However, the common method of the existing technology is to first sample the river water and then conduct sediment testing on the sampled river water. Although this method is widely used in sediment monitoring, it takes a certain amount of time to conduct laboratory analysis after sampling, and it is impossible to achieve real-time monitoring, resulting in data lag. In the case of rapid changes in sediment flow, the sampling method cannot reflect the current sediment conditions in a timely manner. In order to improve the accuracy of the data, frequent sampling will increase manpower and material costs, making it difficult to conduct periodic real-time monitoring of river sediment flow.

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

DETAILED DESCRIPTION

[0033] In order to make the technical means, technical features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0034] Example: Figures 1-11 As shown, the intelligent real-time monitoring device for sediment flow for river hydrological detection described in the present invention includes 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 outside 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 the inner side of the monitoring tube 2 is fixed. A partition plate 3 is installed, two water inlets 4 are opened through one side of the monitoring tube 2, and two water outlets 5 are opened through 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, and 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. After the monitoring tube 2 sinks into the water, an air cavity 25 is formed inside it.

[0035] Specifically, the fixing frame 1 can provide fixed support for the monitoring tube 2, the monitoring tube 2 can provide threaded penetration space for the right sealing plate 6 and the left sealing plate 14, and the right sealing plate 6 and the left sealing plate 14 can provide sealing for the monitoring tube 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 separate the monitoring tube 2 into two independent spaces, so that the two collecting mechanisms 10 can work separately, the monitoring tube 2 can provide penetration space for the water inlet 4 and the water outlet 5, the water inlet 4 and the water outlet 5 are connected. The flat mesh cylinder 101 is aligned so that the flowing water can pass through the water inlet 4 into the inner side of the mesh cylinder 101. The bottom wall of the water outlet 5 is relatively low, which facilitates the mud and sand flushed out of the mesh cylinder 101 to overflow through the water outlet 5. The height of the left protective cover 23 is lower than the right protective cover 7, so that the left water wheel 242 is impacted by the flowing water more than the right water wheel 9, thereby making the rotation speed of the left water wheel 242 greater than the right water wheel 9, which facilitates the subsequent process of the right water wheel 9 driving the rotating shaft 8 to rotate 90°. The left water wheel 242 can quickly move away from the left sealing plate 14 first, so that the resistance plate 18 can quickly reset to limit the resistance rod 12.

[0036] In this embodiment, two collecting mechanisms 10 are fixedly installed on the outer side of the rotating shaft 8. The collecting mechanism 10 is assembled to drive the two mesh cylinders 101 to rotate through the rotating shaft 8, so that the mesh cylinder 101 in the horizontal position cooperates with the filter screen 104 to collect mud and sand, and the mesh cylinder 101 in the vertical position cooperates with the filter screen 104 to move the collected mud and sand out to the air cavity 25 for detection; the collecting mechanism 10 includes a mesh cylinder 101, and a filter screen 104 is provided on the inner side of the mesh cylinder 101. The mesh cylinders 101 of the two collecting mechanisms 10 are perpendicular to each other. The collecting mechanism 10 also includes a fixing ring 102. The two fixing rings 102 are fixedly installed on the inner side of the mesh cylinder 101. The two fixing rings 102 are fixedly installed with annular pressure sensors 103 on the side away from each other, and the two pressure sensors 103 are fixedly connected to the filter screen 104 on the side away from each other.

[0037] Specifically, the mesh tube 101 can provide a stable support for the fixed ring 102, and the fixed ring 102 can provide a stable support for the pressure sensor 103 and the filter 104. The mesh tube 101 and the filter 104 can facilitate the air to pass through arbitrarily, preventing the mesh 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 situation. The pressure change of the pressure sensor 103. The pressure sensor 103 is first continuously impacted by the river water during the filtration and collection process. As the filtration 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 value when the pressure of the pressure sensor 103 gradually decreases to a stable value.

[0038] 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. 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 pass through the interior of the two net cylinders 101 respectively. 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 on 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 interference rods 12 are fixedly installed on the outside of the turntable 11, and a rotating groove 13 is provided on the side of the turntable 11 away from the left sealing plate 14.

[0039] 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, and 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 interference rod 12. The working state of the rotating shaft 8 is determined by limiting or releasing the limitation of the interference 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.

[0040] 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 the center of the rotating shaft 8. A guide rod 16 is fixedly installed on the inner side of the limiting groove 15, and 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 resistance plate 18 is fixedly installed on the other end of the spring 17, and the resistance plate 18 is slidably installed on the outer side of the guide rod 16. A slope is provided on the side where the two resistance plates 18 are close to each other. The resistance plate 18 is slidably installed on the inner side of the limiting groove 15, and the resistance plate 18 contacts and cooperates with the resistance rod 12. The left sealing plate 14 is far away 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 is 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 the other end of the spring 20 is fixedly installed with a pressure plate 21, and the pressure plate 21 is slidably installed on the outside of the limit rod 19, and the pressure plate 21 is located on the outside of the reciprocating screw rod 241. Two push plates 22 are fixedly installed on the side of the pressure plate 21 close to the left sealing plate 14, and 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 with and cooperate with the contact plate 18.

[0041] Specifically, the left sealing plate 14 can provide a space for the limiting groove 15, and 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, and the spring 17 can provide a reset driving force for the contact plate 18. When the contact plate 18 contacts the contact rod 12, it can provide a limiting effect for the contact rod 12, thereby providing a limiting effect for the rotating shaft 8. The left sealing plate 14 can provide a stable support for the limiting rod 19, and the limiting The positioning plate can provide a limiting and guiding function 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 effect 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 the interference rod 12, thereby releasing the limitation on the rotating shaft 8.

[0042] In this embodiment, a reciprocating mechanism 24 is provided on the side of the left sealing plate 14 away from the monitoring tube 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 screw 241 and the threaded teeth 243, so that the extrusion ring 244 intermittently squeezes the pressure plate 21, and 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 detection. The reciprocating mechanism 24 includes a reciprocating screw 241 and a reciprocating screw. A left water wheel 242 is provided on the outer side of 241 through a threaded tooth 243, and an extrusion ring 244 is fixedly installed on one side of the left water wheel 242. One end of the reciprocating screw rod 241 is fixedly installed on the inner wall of one side of the left protective cover 23, and the other end of the reciprocating screw rod 241 is embedded in the inner side of the rotating groove 13 through a bearing. The threaded tooth 243 and the reciprocating screw rod 241 are threadedly matched 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 protective cover 23.

[0043] Specifically, the left protective cover 23 can provide stable support for the reciprocating screw 241, and the left water wheel 242 can provide stable support for the thread teeth 243. The thread teeth 243 can have a threaded effect with the reciprocating screw 241, so that 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 screw 241, so that the left water wheel 242 moves left and right during the rotation process. The left water wheel 242 can provide stable support for the extrusion ring 244, and the extrusion ring 244 can provide a rotation space for the tapered roller 245. When the extrusion ring 244 moves to the right to extrude the pressure plate 21, the tapered roller 245 in the extrusion ring 244 contacts the pressure plate 21, so that the extrusion ring 244 squeezes the pressure plate 21 to the right through the tapered roller 245. The tapered roller 245 rotates during the extrusion process to reduce the friction between the extrusion ring 244 and the pressure plate 21.

[0044] Working principle: The staff first installs the device in the river water through the fixing frame 1, so that the water inlet 4 faces the direction of the river flow. The air inside the monitoring tube 2 does not have time to escape and stays in the monitoring tube 2 to form an air cavity 25. Figure 11 As shown;

[0045] At this time, the left mesh drum 101 is in a horizontal state, and the river water drives the silt to enter the left mesh drum 101 through the water inlet 4, and the silt is filtered by the filter screen 104 in the left mesh drum 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. The left water wheel 242 drives the thread teeth 243 to rotate, so that the thread teeth 243 utilizes 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 tapered roller 245 in the extrusion ring 244 contacts the pressure plate 21, so that the extrusion ring 244 44 squeezes the pressure plate 21 to the right side through the tapered roller 245. The tapered roller 245 rotates during the squeezing process to reduce the friction between the squeezing ring 244 and the pressure plate 21. The pressure plate 21 moves to the right side under the guidance of the limit rod 19, and the pressure plate 21 squeezes the spring 20 to be compressed and deformed. At the same time, the pressure 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 limit groove 15, and squeezes the spring 17 to be compressed and deformed.

[0046] When the contact plate 18 moves to separate from the contact rod 12, the rotation shaft 8 loses its limit and is unlocked. Then, the right water wheel 9 drives the rotation shaft 8 to rotate under the impact of the river water. During the rotation of the rotation 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 rod 241, and under the action of the thread of the reciprocating screw rod 241, the left water wheel 242 moves to the left 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, the pressure plate 21 is pushed away from the left sealing plate 14 by the elastic force of the spring 20, so that the push plate 22 no longer presses the contact plate 18, so that the contact plate 18 is reset under the elastic force of the spring 17.

[0047] After the contact plate 18 is reset, the shaft 8 rotates 90° under the action of the right water wheel 9, causing the shaft 8 to drive the turntable 11 to rotate 90°, thereby causing the contact rod 12 near the front to rotate to the top and contact the contact plate 18. The shaft 8 is again limited by the interference between the contact plate 18 and the contact rod 12. Although the right water wheel 9 is constantly impacted by the river water and does not rotate, it continuously provides rotational driving force for the shaft 8, so that the limiting effect of the contact rod 12 and the contact plate 18 continues.

[0048] After the shaft 8 rotates 90°, the two net cylinders 101 rotate 90° driven by the shaft 8. The net cylinder 101 on the left that filters the sediment rotates to a vertical state, and the filter screen 104 that collects the sediment rotates to the inside of the air cavity 25, exposing the filter screen 104 and the sediment to the air, so that the water in the sediment gradually leaks out. After the right net cylinder 101 rotates 90°, it will continue to filter and collect the sediment in the river water. The two net cylinders 101 perform the river water leakage and filtering and collecting processes respectively. During this process, the left water wheel 242 is in The river water impact and the reciprocating screw 241 cause the reciprocating motion, providing sufficient time for the river water to seep and filter. When the left water wheel 242 completes a reciprocating process, the two mesh cylinders 101 rotate 90 degrees again. At this time, the filter screen 104 that is leaking river water rotates to a position close to the water outlet 5. The river water passing through the mesh cylinder 101 will flush the sediment on the surface of the filter screen 104, washing away the sediment after the river water seeps. The filter screen 104 at the other end of the mesh cylinder 101 will filter and collect again.

[0049] During this process, the pressure sensor 103 is first continuously impacted by the river water during the filtration and collection process, and as the filtration 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 level. 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 value when the pressure of the pressure sensor 103 gradually decreases to a stable level.

Those skilled in the art should understand that the present invention is not limited to the above-described embodiments. The above-described embodiments and descriptions are merely illustrative of the principles of the present invention.
