[0002] In the process of monitoring water conservancy projects, water level monitoring is an indispensable and important link. Water level monitoring mainly monitors the water depth of water bodies at dams, canals, rivers, etc. At present, water level monitoring mostly takes the form of setting up benchmarks to mark the water level height. When the water level rises rapidly, it is impossible to actively alarm, and when weeds are entangled on the monitoring components, they cannot be automatically cleaned, affecting the accuracy of water level monitoring.

[0003] Therefore, the present application provides a water conservancy monitoring device for a water conservancy project, which is convenient for water level monitoring of the water conservancy project and for staff to grasp water level changes in a timely manner, while solving the problem that the existing water level monitoring device does not have an automatic cleaning function.

The monitoring airbag is arranged at the lower part of the connecting seat. One end of the monitoring airbag is a tightening end, and the other end of the monitoring airbag is a telescopic end. The two opposite fan-shaped surfaces of the monitoring airbag are telescopic surfaces. By adjusting the expansion degree of the monitoring airbag, the draft depth of the monitoring part can be adjusted.

[0006] As an optimization, the support part includes a support seat, a connecting arm and an adjustment frame, the support seat is vertically arranged, the connecting arm is connected to the upper part of the support seat obliquely upward, the adjustment frame is rotatably connected to the outer end of the connecting arm, the support seat is equipped with a winding motor, a tightening rope is arranged on the connecting shaft of the winding motor, the tightening rope is laid along the length direction of the connecting arm and the adjustment frame, and the outer end of the tightening rope is connected to the middle part of the adjustment frame; The connecting arm and the rotating shaft of the adjusting frame are provided with a first angle sensor.

[0007] As an optimization, the monitoring frame and the front end of the supporting part are rotatably arranged, and the monitoring frame can rotate horizontally around the connecting axis with the supporting part. Limiting iron blocks are arranged at both ends of the monitoring frame, and the adjusting frame is correspondingly provided with limiting electromagnets. When the limiting iron block rotates to the lower side of the limiting electromagnet, the limiting electromagnet can magnetically attract the limiting iron block.

[0008] As an optimization, the adjustment frame is equipped with an adjustment seat, which can move along the length direction of the adjustment frame, and the lower part of the adjustment seat is rotatably connected with an adjustment shaft, and a second angle sensor is provided at the connection between the adjustment shaft and the adjustment seat; The lower end of the adjusting shaft is rotatably connected to the monitoring frame, and the connecting axis direction of the adjusting shaft and the monitoring frame is perpendicular to the axial direction of the adjusting seat.

[0009] As an optimization, the connecting seat includes a vertical connecting rod and a horizontally arranged mounting plate, the upper end of the connecting rod is connected to the monitoring frame, and the monitoring airbag is arranged on the lower side of the mounting plate; The mounting plate is provided with a tightening assembly and an air pump.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0025] like Figure 1-8 As shown, a water conservancy monitoring device for a water conservancy project includes a support part, the front end of which can swing up and down, the front end of which is rotatably connected to a horizontally arranged monitoring frame 7, and two ends of the monitoring frame 7 are respectively connected to two monitoring parts; The monitoring part includes a connecting seat and a monitoring airbag 6, the monitoring airbag 6 is arranged at the lower part of the connecting seat, one end of the monitoring airbag 6 is a tightening end, and the other end of the monitoring airbag 6 is a telescopic end. The two opposite fan-shaped surfaces of the monitoring airbag 6 are telescopic surfaces. By adjusting the expansion degree of the monitoring airbag 6, the draft depth of the monitoring part can be adjusted.

[0026] The sector surface is in the shape of an accordion leaf, and the two sector surfaces are connected by elastic material. The bottom of the monitoring airbag 6 is horizontal and the whole is made of sealing material.

[0027] The monitoring frame 7 is arranged horizontally. When the monitoring part is monitoring the water level, the heights of the two monitoring parts are flush. When the water level changes, the height of the monitoring part will also change accordingly. Similarly, the monitoring part will drive the front end of the supporting part to swing up and down.

[0028] like Figure 1 As shown, the support part includes a support seat 1, a connecting arm 2 and an adjusting frame 3, the support seat 1 is vertically arranged, the connecting arm 2 is connected to the upper part of the support seat 1 obliquely upward, the adjusting frame 3 is rotatably connected to the outer end of the connecting arm 2, the support seat 1 is equipped with a winding motor 5, a tightening rope 4 is arranged on the connecting shaft of the winding motor 5, the tightening rope 4 is laid along the length direction of the connecting arm 2 and the adjusting frame 3, and the outer end of the tightening rope 4 is connected to the middle part of the adjusting frame 3; The connecting arm 2 and the rotating shaft of the adjusting frame are provided with a first angle sensor 8 .

[0029] When the adjustment frame 3 is in a horizontal state, the angle value of the first angle sensor 8 is reset to 0. When the adjustment frame 3 and the monitoring part are installed, the angle change value monitored by the first angle sensor 8 is γ. When the monitoring part rises or falls, the first angle sensor 8 will again monitor the corresponding angle change α, and the change value of the water level can be calculated based on the angle change.

[0030] like Figure 1-Figure 3 As shown, the monitoring frame 7 is rotatably arranged with the front end of the supporting part, and the monitoring frame 7 can be horizontally rotated around the connecting axis with the supporting part. Limiting iron blocks 9 are arranged at both ends of the monitoring frame 7, and the adjusting frame 3 is correspondingly provided with limiting electromagnets 10. When the limiting iron block 9 rotates to the lower side of the limiting electromagnet 10, the limiting electromagnet 10 can magnetically attract the limiting iron block 9.

[0031] When the monitoring airbags 6 of the two monitoring parts are deployed to different sizes, the impact forces of the water flow on the two monitoring airbags 6 are different, and the different forces on the two will cause the monitoring frame 7 to rotate. When the monitoring frame 7 rotates, the limit iron block 9 will pass the lower side of the limit electromagnet 10. At this time, the limit electromagnet 10 can be energized to magnetically attract the limit iron block 9. When the limit electromagnet 10 releases the limit iron block 9, the recovery speed of the monitoring frame 7 is compared with the set threshold to know whether the water flow rate is accelerated.

[0032] The threshold value can be set before the device is installed, and the time required for the monitoring frame 7 to recover can be measured by simulating the flow rate of water under normal conditions. The recovery time of the monitoring frame 7 varies with the length of the monitoring frame 7, which will not be described in detail again.

[0033] like Figure 1 As shown, the adjustment frame 3 is equipped with an adjustment seat 11, which can move along the length direction of the adjustment frame 3. The lower part of the adjustment seat 11 is rotatably connected with an adjustment shaft, and a second angle sensor 12 is provided at the connection between the adjustment shaft and the adjustment seat 11; The lower end of the adjusting shaft is rotatably connected to the monitoring frame 7 , and the connecting axis direction of the adjusting shaft and the monitoring frame 7 is perpendicular to the axial direction of the adjusting seat 11 .

[0034] The adjusting seat 11 is provided with a connecting hole inside, and the connecting hole is used to accommodate the adjusting frame 3 . The adjusting seat 11 is provided with a locking bolt, and the position of the adjusting seat 11 and the adjusting frame 3 can be locked when the locking bolt is tightened.

[0035] When the monitoring frame 7 rotates, the second angle sensor 12 can monitor the rotation angle of the monitoring frame 7 and whether the monitoring frame 7 is reset.

[0036] like Figure 1 and Figure 5As shown, the connecting seat includes a vertical connecting rod 13 and a horizontally arranged mounting plate 14, the upper end of the connecting rod 13 is connected to the monitoring frame 7, and the monitoring airbag 6 is arranged on the lower side of the mounting plate 14; The mounting plate 14 is provided with a tightening assembly and an air pump 15 . The tightening assembly is connected to the telescopic end of the monitoring airbag 6 , and the air pump 15 is connected to the upper part of the monitoring airbag 6 .

[0037] A hose is connected between the air pump 15 and the monitoring airbag 6 , and the tightening assembly is used to tighten the telescopic end of the monitoring airbag 6 .

[0038] like Figure 5 As shown, the locking assembly includes a tightening motor 16 and an adjusting rope 17, one end of the adjusting rope 17 is connected to the connecting shaft of the tightening motor 16, and the other end of the adjusting rope 17 passes through the telescopic end from top to bottom to connect to the bottom of the monitoring airbag 6. When the adjusting rope 17 is tightened, the telescopic end is compressed.

[0039] The adjustment rope 17 located inside the monitoring airbag 6 is equipped with a reset spring. When the adjustment rope 17 is tightened, the reset spring contracts. When the adjustment rope 17 is loosened, the monitoring airbag 6 can be quickly deployed under the action of the reset spring. The setting of the adjustment rope 17 does not affect the sealing of the monitoring airbag 6.

[0040] like Figure 1 and Figure 4 As shown, the support part is fixed to the bank of the water conservancy project, and the monitoring frame 7 is arranged along the direction of the water flow. The monitoring airbag 6 is set in the river channel by adjusting the height of the front end of the support part, and the draft of the monitoring airbag 6 is adjusted by adjusting the inflation degree of the monitoring airbag 6 and the height of the monitoring airbag 6. When the monitoring part needs to be cleaned, the monitoring part is rotated and the directions of the two monitoring airbags 6 are reversed.

[0041] It also includes a controller, which is connected to the supporting part and the monitoring part through lines.

[0042] The position of the controller in this solution is set by the staff according to the actual situation during operation. The controller is used to control the electrical devices used in this solution, including but not limited to sensors, motors, telescopic rods, water pumps, solenoid valves, heating wires, heat pumps, display screens, computer input devices, switch buttons, communication equipment, lights, speakers and microphones; the controller is an Intel processor, AMD processor, PLC controller, ARM processor or a single-chip microcomputer, and the supporting motherboard, memory stick, storage medium and power supply are also used therewith, and the power supply is AC power or a lithium battery; when a display screen is provided, a display card is also provided.

[0043] Directions: When the device is used, the support base 1 is fixed to the bank of the water conservancy project by anchor bolts or other fasteners, the monitoring frame 7 and the adjustment frame 3 are both set horizontally, the monitoring value of the first angle sensor 8 is reset, the two monitoring parts are extended into the water flow, and it is determined that there is no obstruction in front and behind the monitoring parts; The air pump 15 is operated to shrink the two side elevations of the monitoring airbag 6, and the adjustment rope 17 is released, and the reset spring is at its maximum length. At this time, the gravity of the monitoring airbag 6 is greater than the buoyancy of the water on the monitoring airbag 6, and the monitoring airbag 6 is partially submerged in the water. By running the winding motor 5, the tightening rope 4 is released to a suitable length, so that the lower part of the monitoring airbag 6 can be submerged in the water, and the submerged depths of the two monitoring airbags 6 are the same; The monitoring airbag 6 is inflated by the air pump 15 until the monitoring airbag 6 can float in the water. Due to the influence of water depth and water flow, the inflation degree of the two monitoring airbags 6 may be the same or may not be the same; When the monitoring airbag 6 floats, the tightening rope 4 is loosened, and the monitoring frame 7 is supported by the buoyancy of the monitoring airbag 6, and the device as a whole maintains force balance. At this time, the adjustment frame 3 will rise or fall slightly, and the monitoring value of the first angle sensor 8 is γ; When the water level rises or falls, the position of the monitoring airbag 6 will change with the change of the water level; the monitoring airbag 6 will pull the monitoring frame 7 and the adjustment frame 3 to move, so that the angle between the adjustment frame 3 and the connecting arm 2 changes by α, and the first angle sensor 8 transmits the angle signal to the controller, and the controller can calculate the water level change value through the angle value; like Fig. 9 As shown, when the first angle sensor 8 detects that the rotation angle of the adjustment frame 3 is positive α (upward rotation), it indicates that the water level rises; when the first angle sensor 8 detects that the rotation angle of the adjustment frame 3 is negative α (downward rotation), it indicates that the water level drops; The calculation process of water level change height d is as follows: Combination Fig. 9 , and according to the cosine theorem:

[0044]

[0045]

[0046] Among them, the rod length is l, the undulation angle is α, the initial angle is γ, and the water level height change is d.

[0047] When there are debris such as water plants hanging on the outside of the two monitoring airbags 6, there will be more debris on the upstream monitoring airbag 6 than on the downstream monitoring airbag 6. At this time, the air pump 15 is operated to inflate the upstream monitoring airbag 6; the tightening motor 16 of the downstream monitoring airbag 6 is operated to shorten the adjustment rope 17 of the monitoring airbag 6. Due to the fluctuation and instability of the water flow, the monitoring airbag 6 drives the monitoring frame 7 to deflect; At this time, the second angle sensor 12 detects the angle change, and the limit electromagnet 10 is energized, and the limit electromagnet 10 magnetically attracts the limit iron block 9 passing through it, so that the length direction of the monitoring frame 7 is parallel to the length direction of the adjustment frame 3; Then the limit electromagnet 10 is powered off, releasing the limit iron block 9, so that the two monitoring airbags 6 continue to rotate under the action of the water flow, and the positions of the two monitoring airbags 6 are swapped to achieve reverse flushing of the debris by the water flow.

[0048] After the limit electromagnet 10 is powered off, the speed of the water flow can be judged based on the angle change time of the monitoring frame 7 monitored by the second angle sensor 12; under normal conditions in this water area, the water flow impacts the monitoring airbag 6, and the time used for the monitoring frame 7 to rotate 90° is c. When the second angle sensor 12 detects that the time taken for the monitoring frame 7 to rotate 90° is less than c, it indicates that the water flow speed is accelerating; otherwise, it indicates that the water flow is slowing down.

[0049] After the monitoring airbags 6 are cleaned, the winding motor 5 and the air pump 15 are operated to restore the shapes of the two monitoring airbags 6 to their initial positions.

[0050] During use, the limit electromagnet 10 can also be used to magnetically attract the limit iron block 9 to check whether the river flow rate has reached the alarm threshold, which is particularly suitable for monitoring river conditions during the flood season. The magnetic attraction of the limit electromagnet 10 is adjusted according to actual use needs. Under the impact of the water flow on the monitoring part, when the limit iron block 9 is disengaged from the limit electromagnet 10, it indicates that the water flow rate is too high and the staff needs to be reminded.

[0051] When the limit electromagnet 10 is unable to magnetically attract the limit iron block 9, the water flow rate value is set as the alarm upper limit value. The limit electromagnet 10 can periodically magnetically connect the limit iron block 9 to periodically monitor the water flow rate. When the water flow rate is too high, the controller executes the command to the alarm device, or reminds the staff in other forms. Correspondingly, the alarm device can be a speaker, a flash light, etc., and it is well known to those skilled in the art to set a proximity switch, a speed sensor, etc. according to actual use to monitor the rotation and position changes of the device, which will not be repeated here.

The patent protection scope of the present invention includes but is not limited to the product form and style of the above-mentioned specific implementation.
