[0008] Vertical shafts are installed on the riverbank;
[0009] The water guiding assembly includes a first water pipe and a second water pipe. The first water pipe is vertically installed in the shaft, with its top end located at the shaft opening and its bottom end extending to the bottom of the shaft. One end of the second water pipe is connected to the bottom end of the first water pipe, and the other end of the second water pipe extends through the side wall of the shaft into the river water. The second water pipe is used to guide river water into the first water pipe so that the water level in the first water pipe is level with the water level in the river.

[0011] A hydrological monitoring water level monitoring device according to an embodiment of the present utility model has at least the following beneficial effects:
[0012] 1. This utility model indirectly monitors water levels by placing the water level monitoring component in the first water pipe inside the vertical shaft of the river embankment and using a second water pipe to introduce river water into the closed first water pipe. This allows staff to perform maintenance operations from a location in the vertical shaft away from the water area, effectively avoiding the risk of falling into the water.
[0013] 2. The first water pipe of this utility model is connected to the river water through the second water pipe. By utilizing the principle of communicating vessels, the water levels of the first water pipe and the river water are synchronized, effectively ensuring the consistency between the monitoring data and the actual water level of the river water.
[0014] According to some embodiments of the present invention, the water guiding assembly further includes a sealing box located at the bottom of the vertical shaft, the bottom end of the first water pipe being connected to the sealing box, and one end of the second water pipe being connected to the sealing box.
[0015] The advantages of this invention are: by setting a sealing box at the bottom of the shaft, connecting the bottom end of the first water pipe to the sealing box, and connecting one end of the second water pipe to the sealing box, it can be understood that the sealing box, as the connection hub of the first and second water pipes, can effectively prevent groundwater from seeping into the bottom of the shaft and affecting the operation of the equipment.

[0019] The advantage of this invention is that by including a metal pipe in the water guiding component, one end of the metal pipe is set in the vertical shaft, and the other end of the metal pipe extends through the side wall of the vertical shaft to the side of the riverbank close to the river water. The second water pipe extends through the metal pipe into the river water. It can be understood that the metal pipe forms a rigid protective channel to prevent the second water pipe from being deformed by soil pressure when crossing the riverbank and to avoid sharp stones scratching the pipe wall.
[0020] According to some embodiments of the present invention, both ends of the metal pipe are provided with sealing elements for sealing the gap between the inner wall of the metal pipe and the second water pipe.
[0021] The advantages of this invention are that by providing sealing elements at both ends of the metal pipe to seal the gap between the inner wall of the metal pipe and the second water pipe, it can be understood that the double-end sealing design of the metal pipe effectively prevents mud and sand from entering the vertical shaft through the gap in the metal pipe wall, preventing the monitoring system from being blocked. At the same time, the sealing elements form a waterproof barrier to prevent river water from flowing back and causing the vertical shaft to be flooded, ensuring a dry environment for the equipment inside the shaft.
[0022] According to some embodiments of the present invention, the water level monitoring device further includes a lifting frame, which is set on the riverbed or the side of the riverbank, and one end of the second water pipe located in the river water is set on the lifting frame, which is used to drive the end of the second water pipe to rise and fall.
[0023] The advantages of this invention are that the water level monitoring device also includes a lifting frame, which is set on the riverbed or the side of the riverbank. One end of the second water pipe located in the river water is set on the lifting frame. The lifting frame is used to drive the end of the second water pipe to rise and fall. It can be understood that the adjustable lifting frame allows the water intake of the second water pipe to maintain the optimal water intake depth according to seasonal water level changes, avoiding the water intake being exposed during the dry season or submerged during the flood season, thus ensuring the accuracy of water level monitoring.

The threaded connection between the first screw and the lifting part has a self-locking function, which can fix the lifting part at any height position. The structure is simple and reliable, can operate stably without electric drive, and has low maintenance costs.
[0026] According to some embodiments of the present invention, the water level monitoring device further includes a flushing assembly, which is used to flush water into the first water pipe to clean the first water pipe and the second water pipe.

[0028] According to some embodiments of the present invention, the flushing assembly further includes a controller located above the vertical shaft, the controller being electrically connected to the switching valve, and the controller being used to control the switching valve.
[0029] The advantages of this invention are: by setting up a controller located above the shaft and electrically connected to the switching valve, the controller can remotely control the switching valve to achieve automated cleaning. Workers can control the flushing components from outside the shaft, making the control of the flushing components more convenient. At the same time, the design of the controller being placed outside the shaft facilitates the operation and maintenance of the controller, while also preventing the humid environment inside the shaft from affecting the electronic components of the controller.
[0030] According to some embodiments of this utility model, the water level monitoring component is configured as a float-type water level gauge.

[0043] This utility model aims to provide an embodiment of a water level monitoring device for hydrological monitoring.
[0044] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, a hydrological monitoring water level monitoring device mainly includes a vertical shaft 100, a water guiding component 120, and a water level monitoring component 150.
[0045] Shaft 100 is located on river embankment 110.
[0046] The water guiding component 120 includes a first water pipe 130 and a second water pipe 140. The first water pipe 130 is vertically installed in the shaft 100. The top end of the first water pipe 130 is located at the wellhead of the shaft 100, and the bottom end of the first water pipe 130 extends to the bottom of the shaft 100. One end of the second water pipe 140 is connected to the bottom end of the first water pipe 130, and the other end of the second water pipe 140 extends through the side wall of the shaft 100 into the river water. The second water pipe 140 is used to guide river water into the first water pipe 130 so that the water level in the first water pipe 130 is level with the water level in the river.
[0047] In order for the river water to pass smoothly through the second water pipe 140 into the first water pipe 130, the bottom height of the vertical shaft 100 can be lower than the river bottom height.
[0048] In some specific embodiments, the water guiding assembly 120 also includes a sealing box 160, which is located at the bottom of the shaft 100. The bottom end of the first water pipe 130 is connected to the sealing box 160, and one end of the second water pipe 140 is connected to the sealing box 160.
[0049] Understandably, the sealing box 160, as the connecting hub of the first water pipe 130 and the second water pipe 140, can effectively prevent groundwater from seeping into the bottom of the shaft 100 and affecting the operation of the equipment. At the same time, it provides a stable connection point for fixing the first water pipe 130 and the second water pipe 140, reducing the risk of pipe displacement caused by water flow impact.
[0050] In some specific embodiments, the second water pipe 140 is configured as a PVC flexible hose.
[0051] Understandably, PVC hoses have good corrosion resistance and flexibility, which can adapt to changes in riverbed topography and resist the erosion of microorganisms and chemicals in the water. Their bendability makes them easy to lay and install in complex river environments, reducing construction difficulty.
[0052] In some specific embodiments, the water guiding assembly 120 also includes a metal pipe 170, one end of which is disposed in the shaft 100, and the other end of which extends through the side wall of the shaft 100 to the side of the riverbank 110 near the river water. A second water pipe 140 extends through the metal pipe 170 into the river water.
[0053] Understandably, the metal pipe 170 forms a rigid protective channel to prevent the second water pipe 140 from deforming under soil pressure when crossing the river embankment 110, and to avoid sharp stones scratching the pipe wall.
[0054] Furthermore, both ends of the metal pipe 170 are provided with sealing elements 180 for sealing the gap between the inner wall of the metal pipe 170 and the second water pipe 140.
[0055] Understandably, the double-end sealing design of the metal pipe 170 effectively prevents mud and sand from entering the shaft 100 through the gaps in the pipe wall of the metal pipe 170, preventing the monitoring system from becoming clogged. At the same time, the seal 180 forms a waterproof barrier to prevent river water from flowing back and causing the shaft 100 to be submerged, ensuring a dry environment for the equipment inside the shaft.
[0056] In some specific embodiments, the water level monitoring device also includes a lifting frame 190, which is set on the riverbed or the side of the riverbank 110. One end of the second water pipe 140 located in the river is set on the lifting frame 190, and the lifting frame 190 is used to drive the end of the second water pipe 140 to rise and fall.
[0057] Understandably, the adjustable lifting frame 190 enables the water intake of the second water pipe 140 to maintain the optimal water intake depth according to seasonal water level changes, avoiding exposure of the water intake during the dry season or submersion during the flood season, and ensuring the accuracy of water level monitoring.
[0058] Specifically, the lifting frame 190 includes a fixed part 200, a lifting part 210, and a first screw 220. The fixed part 200 is fixed to the riverbed or the side of the riverbank 110. The lifting part 210 is slidably connected to the fixed part. The end of the second water pipe 140 is fixed to the lifting part 210. The first screw 220 is rotatably connected to the fixed part 200 and threadedly connected to the lifting part 210. The first screw 220 rotates to drive the lifting part 210 to rise and fall.
[0059] Understandably, the lifting structure of the first screw 220 provides precise mechanical adjustment, and the threaded connection between the first screw 220 and the lifting part 210 has a self-locking function that can fix the lifting part 210 at any height position. The structure is simple and reliable, can operate stably without electric drive, and has low maintenance costs.
[0060] In some specific embodiments, the water level monitoring device further includes a flushing assembly 230, which is used to flush water into the first water pipe 130 to clean the first water pipe 130 and the second water pipe 140. The flushing assembly 230 includes a water tank 240, a water injection pipe 250, and a switch valve 260. The water tank 240 is located inside the vertical shaft 100. One end of the water injection pipe 250 is connected to the water tank 240, and the other end of the water injection pipe 250 extends into the first water pipe 130. The switch valve 260 is used to open and close the water injection pipe 250.
[0061] Understandably, the flushing assembly 230 can periodically remove silt, biofilm, and air accumulated in the first water pipe 130 and the second water pipe 140, maintaining pipe patency.
[0062] Furthermore, the flushing assembly 230 also includes a controller 270, which is located above the shaft 100 and is electrically connected to the switching valve 260. The controller 270 is used to control the switching valve 260.
[0063] Understandably, the controller 270 enables automated cleaning through remote control. Staff can control the flushing component 230 from outside the shaft 100 via the controller 270, making the control of the flushing component 230 more convenient. At the same time, the design of the controller 270 being external to the shaft 100 facilitates the operation and maintenance of the controller 270, while also preventing the humid environment inside the shaft from affecting the electronic components of the controller 270.
[0064] The water level monitoring component 150 is used to monitor the water level in the first water pipe 130.
[0065] Specifically, the water level monitoring component 150 is configured as a float-type water level gauge.
[0066] Understandably, float-type water level gauges use the magneto-optical coding principle for measurement, which offers high measurement accuracy, good stability, and is free from the influence of temperature drift and time drift. The signal can be directly connected to a computer to achieve automatic monitoring of water level changes.
[0067] More specifically, the float-type water level gauge includes a float 280, a suspension cable 290, a water level wheel 310, a counterweight 300, and a water level encoder 320. The float 280 floats on the water surface in the first water pipe, the counterweight 300 is set above the vertical shaft, the float 280 and the counterweight 300 are respectively connected to the two ends of the suspension cable 290, the suspension cable 290 is suspended on the water level wheel 310, the counterweight 300 is used to tighten the suspension cable 290, the water level wheel 310 is coaxially connected to the water level encoder 320, and the water level encoder 320 rotates once for every revolution of the water level wheel 310. The water level encoder 320 is used to display the water level reading.
[0068] In some specific embodiments, a support is also provided above the shaft 100, and the water level wheel 310 is rotatably mounted on the support, thereby facilitating the support to support the rotation of the water level wheel 310.
[0069] To make the suspension cable 290 more stable on the water level wheel 310, an annular groove can be provided on the outer circumferential surface of the water level wheel 310, and the suspension cable 290 can be placed in the annular groove, which can limit the movement of the suspension cable 290.
[0070] In this embodiment, the water level monitoring component 150 is installed in the first water pipe 130 inside the vertical shaft 100 of the river embankment 110, and the river water is introduced into the closed first water pipe 130 through the second water pipe 140 for indirect monitoring. This allows the staff to carry out maintenance operations at the vertical shaft 100, which is far away from the water area, effectively avoiding the risk of falling into the water.
[0071] In this embodiment, the first water pipe 130 is connected to the river water through the second water pipe 140. The water level of the first water pipe 130 and the river water are synchronized by using the principle of communicating vessels, which effectively ensures the consistency between the monitoring data and the actual water level of the river.
