Technical Field

[0001] The present invention relates to the field of water conservancy monitoring, and in particular to a monitoring device and a monitoring system for water conservancy projects. Background Art

[0002] The measurement of water level and flow velocity is an important part of flood monitoring indicators. Existing water level and flow velocity detection devices are generally divided into two categories, one is radar water level and flow velocity detection, and the other is immersion water level and flow velocity detection. For convenience, staff often use immersion water level and flow velocity detection to detect water level and flow velocity.

[0003] However, when the immersive water level and flow velocity detection device is in use, once heavy rain occurs, the increased flow velocity in the river channel will drive the sensing structure to rotate around the rope-releasing point, causing the sensing structure to leave the original water level, making it impossible for the device to accurately detect the water level and flow velocity at the corresponding position.

[0004] Therefore, when the above monitoring device is in use, the probe will be driven to swing when the flow rate increases, and the swinging of the probe will cause the water level detected by the probe to change, which will affect the monitoring accuracy of the entire device to a certain extent.

[0018] Beneficial effects of the present invention:

[0019] 1. On the basis of conventional water conservancy monitoring devices, the immersion water level monitoring structure is improved, and the swing angle of the water level monitoring probe put into the water is monitored by setting a monitoring component, and the connecting rope is retracted and released through the driving component according to the swing angle, so that the water level monitoring probe can return to the original monitoring water level, so that the water level monitoring probe can maintain the same water level monitoring to a certain extent, thereby improving the working efficiency of the entire monitoring device to a certain extent;

[0020] 2. When the flow rate increases, due to the deadweight of the recovery component and the sliding component, a part of the connecting rope extending out of the connecting arc bar will rotate due to the swing of the water level monitoring probe in the water, and a part of the rotating connecting rope will squeeze the rotating bar, thereby causing the rotating bar to rotate. The second rotary encoder connected to the pressure plate is used to monitor the rotation angle of the rotating bar, so that when the first rotary encoder does not monitor the data, the water level monitoring probe with water level changes can still be adjusted, thereby greatly improving the monitoring accuracy of the entire monitoring device;

[0021] 3. With the increase of rain, the flow velocity in the river channel will often change. When a certain amount is accumulated, it will inevitably cause floods. When floods occur, the flow velocity of the water in the river channel will increase significantly, and the water level in the river channel will also rise significantly. The increase in the flow velocity in the river channel will also cause the connecting rope to swing excessively. When the sliding component slides to one end of the connecting arc bar, the pressure plate will squeeze the pressure plate, and squeeze the pressure sensor through the moving pressure plate, and make the pressure sensor sense the pressure transmitted by the pressure plate. When the pressure applied by the pressure plate exceeds the rated value, the first motor can be reversed to rotate the retractable rack to drive the connecting rope connected to the retractable rack to be rewound on the retractable rack, thereby preventing the flood from impacting the water level monitoring probe and causing the water level monitoring probe to detach to a certain extent.

[0038] The driving assembly 2 includes a protective cover 201 connected to the water flow monitoring assembly 1, a passive rotating wheel 202 movably connected to the protective cover 201, a fixing bar 205 connected to the translation assembly 3, a first motor 204 connected to the fixing bar 205, and an active rotating wheel 203 connected to the output shaft of the first motor 204, wherein the active rotating wheel 203 is meshed with the passive rotating wheel 202, and the first motor 204 is used to drive the passive rotating wheel 202 to rotate around its own central axis;

[0039] The monitoring component 4 includes a connecting head 401 connected to the translation component 3, a rotating rod 405 movably connected to the connecting head 401, a rotating head 402 connected to the rotating rod 405, a telescopic sleeve 403 connected to the rotating head 402, a telescopic strip 404 movably connected to the telescopic sleeve 403, a first rotary encoder 406 connected to the rotating rod 405, and a mounting bracket 407 connected to the first rotary encoder 406, the mounting bracket 407 is connected to the fixed bar 205, and the first rotary encoder 406 is used to monitor the rotation angle of the rotating rod 405 around its own central axis.

[0040] It should be noted that the active rotating wheel 203 is driven to rotate by the first motor 204, and the rotating active rotating wheel 203 drives the passive rotating wheel 202 meshing therewith to rotate, and synchronously drives the storage rack 101 connected to the passive rotating wheel 202 to rotate, so that the connecting rope 103 connected to the storage rack 101 can be released or tightened, so that the extension length of the water level monitoring probe 104 can be adjusted, and at the same time, the rotating rod 405 connected to the rotating head 402 can also rotate synchronously when the telescopic bar 404 swings, and the rotating rod 405 can be rotated by setting the first rotary encoder 406, and the rotating rod 405 can be monitored by the first rotary encoder 406 connected to the rotating rod 405.

[0041] according to Figure 2-4 As shown, the water flow monitoring assembly 1 includes a fixing clamp 102 connected to the protective cover 201, a retractable rack 101 movably connected to the fixing clamp 102, a connecting rope 103 connected to the retractable rack 101, and a water level monitoring probe 104 connected to the connecting rope 103. The connecting rope 103 is used to adjust the distance that the water level monitoring probe 104 extends into the water surface. The water level monitoring probe 104 is used to monitor the changes in water level and flow rate in the river channel.

[0042] It should be noted that the connecting rope 103 is retracted and extended by the retracting and extending frame 101, and the water level and flow rate of the water flow inside the riverbed to be measured are monitored by the provision of the water level monitoring probe 104.

[0043] according to Figure 3-4 As shown, the translation assembly 3 includes a screw rail 301 connected to the fixed bar 205, a screw slider 302 movably connected to the screw rail 301, a rotating wheel frame 303 connected to the screw slider 302, and a plurality of tensioning wheels 304 movably connected to the rotating wheel frame 303, and the plurality of tensioning wheels 304 are used to tension the connecting rope 103 against the tensioning wheel 304.

[0044] It should be noted that the position of the rotating wheel frame 303 is adjusted by the cooperation between the screw guide rail 301 and the screw slider 302, so that the retracted connecting rope 103 can be tensioned by a plurality of tensioning wheels 304 to prevent the connecting rope 103 from detaching during the retraction process.

[0045] according to Figure 7 As shown, the bracket assembly 5 includes a mounting bar 501 connected to the fixing bar 205, a connecting bar 502 connected to the mounting bar 501, a handle bar 503 connected to the connecting bar 502, a plug-in bar 505 connected to the handle bar 503, a connecting ground pin 506 connected to the plug-in bar 505, and a fixed handle 504 connected to the handle bar 503.

[0046] It should be noted that the monitoring device can be held by holding the fixed handle 504 , and can also be connected to the ground by connecting the ground pin 506 on the plug-in strip 505 .

[0047] according to Figure 6 , Figure 8-9 and Fig.12 As shown, the arc bar assembly 6 includes a fixed column 601 movably connected to the mounting bar 501, a fixed plate 604 connected to the fixed column 601, a positioning rod 605 movably connected to the fixed plate 604, a pressure plate 608 connected to the positioning rod 605, a return spring 606 connected to the pressure plate 608, a pressure sensor 607 connected to the fixed plate 604, a connecting arc bar 602 connected to the fixed plate 604, and a plurality of meshing teeth 603 connected to the connecting arc bar 602, the pressure sensor 607 is used to detect the pressure applied by the pressure plate 608, and the plurality of meshing teeth 603 are used to drive the sliding assembly 7 to slide along the connecting arc bar 602.

[0048] It should be noted that the water level monitoring probe 104 pushed by the flood phenomenon will synchronously drive the sliding component 7 to slide in the connecting arc bar 602. When the sliding component 7 slides to one end of the connecting arc bar 602, the pressure plate 707 will squeeze the pressure plate 608, and squeeze the pressure sensor 607 through the moving pressure plate 608, and make the pressure sensor 607 sense the pressure transmitted by the pressure plate 608. When the pressure applied by the pressure plate 608 exceeds the rated value, the water level monitoring probe 104 can be recovered by the first motor 204 to prevent the flood phenomenon from impacting the water level monitoring probe 104 and causing the water level monitoring probe 104 to detach.

[0049] according to Figure 8-9 As shown, the sliding assembly 7 includes a fixed block 701 connected to the telescopic strip 404, a wheel frame 702 connected to the fixed block 701, a meshing wheel 703 movably connected to the wheel frame 702, a fixed sleeve 704 movably connected to the meshing wheel 703, a combination head 706 connected to the connecting rope 103, an abutment block 705 movably connected to the combination head 706, and a deflection limiting assembly connected to the wheel frame 702, the meshing wheel 703 is meshed with the meshing teeth 603, and the abutment block 705 is movably connected to the connecting rope 103.

[0050] It should be noted that the water level monitoring probe 104 pushed by the water flow in the river channel will drive the meshing wheel 703 to rotate on the meshing tooth 603, and enable the sliding abutment block 705 to move against the connecting arc bar 602, thereby realizing the pendulum-like adjustment of the water level monitoring probe 104.

[0051] according to Fig. 9 As shown, the deflection limit assembly includes a pressure plate 707 connected to the wheel frame 702, a rotating bar 708 connected to the pressure plate 707 via a rotating shaft, and a second rotary encoder 709 connected to the pressure plate 707, and the second rotary encoder 709 is used to monitor the rotation angle of the rotating shaft on the rotating bar 708 along its own central axis.

[0052] It should be noted that before a flood occurs in a river, rain will raise the water level of the river to a certain extent, and the increased water level will also lead to an increase in the flow rate of the water in the river. However, the slightly increased flow rate may not be able to drive the abutment block 705 to slide in the connecting arc bar 602. The connecting rope 103 extending out of the connecting arc bar 602 can only rotate, and a part of the connecting rope 103 can squeeze the rotating bar 708, so that the rotating bar 708 can rotate. The second rotary encoder 709 connected to the pressure plate 707 is used to monitor the rotation angle of the rotating bar 708 to realize the positioning and identification of slight deflection.

[0054] It should be noted that the follow-up swing of the telescopic reset assembly is achieved through the movably connected T-shaped frame 801 and the rotating bar 802, so that the telescopic reset assembly and the sliding assembly 7 can always be located on the same horizontal longitudinal line, thereby improving the ease of use of the entire recovery assembly 8 to a certain extent.

[0055] according to Figure 10-11 As shown, the telescopic reset assembly includes a hydraulic push rod 804 connected to a reinforcement frame 803, a push bar 805 connected to the hydraulic push rod 804, a connecting column 806 connected to the push bar 805, a limit rod 807 movably connected to the connecting column 806, a limit frame 808 connected to the limit rod 807, an electromagnetic rotary wheel rod 809 movably connected to the limit frame 808, a sliding bar 810 movably connected to the limit frame 808, a second motor 811 connected to the sliding bar 810, and a fixed magnetic block 812 connected to the output shaft of the second motor 811, the electromagnetic rotary wheel rod 809 is connected to the meshing wheel 703 near the telescopic reset assembly, the electromagnetic rotary wheel rod 809 is magnetically connected to the fixed magnetic block 812, the second motor 811 is used to drive the electromagnetic rotary wheel rod 809 to rotate around its own central axis, and the hydraulic push rod 804 is used to drive the sliding bar 810 to slide in the limit frame 808.

[0056] It should be noted that the push bar 805 is driven to move by the hydraulic push rod 804, and the moving push bar 805 drives the connecting column 806 to slide on the limit rod 807, so that the moving connecting column 806 can synchronously drive the sliding bar 810 to move on the limit frame 808. When the fixed magnetic block 812 moves to the electromagnetic wheel rod 809, the fixed magnetic block 812 can be driven to rotate by the second motor 811, and the electromagnetic wheel rod 809 can be synchronously driven to rotate by the rotating fixed magnetic block 812, so that the meshing wheel 703 connected to it can be driven to rotate by the rotating electromagnetic wheel rod 809, so that the combination head 706 can drive the connecting rope 103 connected to it to move, thereby driving the water level monitoring probe 104 to reset through the connecting rope 103 and returning it to its initial state.

[0057] In one embodiment of the present invention, according to Fig.13As shown, a monitoring system for a water conservancy project includes a monitoring device for a water conservancy project as described above, and also includes a control module 10, a data transmission module 11 and a data storage module 12 connected to a system box 9, the control module 10 is used to control the operation of the data transmission module 11, the data storage module 12, the first rotary encoder 406, the pressure sensor 607 and the second rotary encoder 709, the data transmission module 11 is used to transmit the electrical signals emitted by the first rotary encoder 406, the pressure sensor 607 and the second rotary encoder 709, and the data storage module 12 is used to back up and store the electrical signals emitted by the first rotary encoder 406, the pressure sensor 607 and the second rotary encoder 709.

[0058] The entire process can be carried out by setting a real-time adjustable driving component 2 to adjust the position of the water level monitoring probe 104, so that the water level monitoring probe 104 will not be affected by the flow rate and water level during the monitoring process. At the same time, the recovery component 8 can also be used to prevent the water level monitoring probe 104 from being detached due to excessive flow rate, thereby greatly improving the portability of the entire detection device.

[0059] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
