Description

Technical Field

[0001] The invention relates to the technical field of video monitoring, and more particularly to a solar energy video monitoring device for a reservoir. Background Art

[0002] Video surveillance devices are widely used in reservoir management. They can be used to monitor the water level of the reservoir in real time and issue early warnings in a timely manner; monitor the water flow status of the reservoir spillway to ensure the safety of the discharge; and monitor the structural safety of the reservoir dam to promptly detect safety hazards such as cracks and displacements;

[0003] Cracks on the dam body of a reservoir are generally caused by external tensile stress or extrusion stress. Some cracks with smaller widths will not pose a significant threat to the overall structure of the dam, but they need to be periodically detected through video monitoring devices to dynamically evaluate the impact of cracks on the safety of the dam structure.

[0004] When existing video surveillance devices detect cracks, since the extension path of the cracks is usually tortuous, the detection route of the monitoring probe in the video surveillance device is difficult to completely overlap with the extension path of the cracks, resulting in an offset between the monitoring probe and the extension path of the cracks, affecting the alignment of the monitoring probe and the cracks, and further affecting the accuracy of the monitoring data.

[0052] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0053] See also Figure 1 and Figure 2The present invention discloses a solar video monitoring device for a reservoir, which is used to monitor cracks 120 on a reservoir dam 100, including a frame 200, a travel drive member 240 arranged on both sides of the frame 200, a swing frame 300 rotatably installed below the frame 200, a positioning member 400 fixedly arranged at one end of the swing frame 300, and a video monitoring unit 500 movably arranged on the swing frame 300;

[0054] See also Figure 6 The positioning member 400 includes a fixed sleeve 410 vertically mounted on the swing frame 300 and a first elastic probe 430 that can move axially along the fixed sleeve 410;

[0055] See also Figure 7 The video monitoring unit 500 includes a transverse driving member 510 disposed on the swing frame 300, a longitudinal moving member 520 connected to the transverse driving member 510, and a patrol guide member 530 and a monitoring probe 540 installed on the longitudinal moving member 520; the patrol guide member 530 includes a vertically distributed movable sleeve 531, a telescopic sleeve rod 532 that can move axially along the movable sleeve 531, and a second elastic probe 533 that can move axially along the telescopic sleeve rod 532;

[0056] When the travel drive member 240 drives the frame 200 to reach the crack 120, the first elastic probe 430 pops out from the fixed sleeve 410 and is inserted into one end of the crack 120, and the second elastic probe 533 pops out from the telescopic sleeve 532 and is inserted into the other end of the crack 120, and the swing frame 300 adaptively deflects; the transverse drive member 510 drives the monitoring probe 540 to move laterally toward one side of the fixed sleeve 410, and at the same time, the longitudinal moving member 520 adaptively adjusts the longitudinal displacement of the monitoring probe 540 according to the moving path of the patrol guide member 530 in the crack 120, so that the monitoring route of the monitoring probe 540 coincides with the extension path of the crack 120.

[0057] Specifically, see Figure 3 , Figure 4 and Figure 5, the frame 200 is driven by the travel drive member 240 to move along the reservoir dam 100 from one end to the other end for inspection. When the frame 200 passes through an area without cracks 120, the first elastic probe 430 and the second elastic probe 533 are elastically extended and abut against the ground of the reservoir dam 100; when the frame 200 passes through an area with cracks 120, even if the extension path of the cracks 120 is curved, one of the first elastic probe 430 and the second elastic probe 533 will inevitably contact one end of the crack 120 first and insert into the crack 120. At this time, the same end of the swing frame 300 cannot move forward synchronously with the frame 200, and the other end of the swing frame 300 Then, it is temporarily unrestricted, so that the swing frame 300 undergoes adaptive deflection until the other of the first elastic probe 430 and the second elastic probe 533 contacts the other end of the crack 120 and is inserted into the crack 120; then the transverse driving member 510 drives the patrol guide member 530 and the monitoring probe 540 to move laterally toward the side of the first elastic probe 430, and at the same time, under the action of the longitudinal moving member 520, the patrol guide member 530 and the monitoring probe 540 can move longitudinally relative to the swing frame 300, so that the patrol guide member 530 can move along the extension path of the crack 120, so that the monitoring probe 540 can monitor and patrol the crack 120 along the extension path of the crack 120.

[0058] It should be noted that since the reservoir dam 100 generates cracks 120 under the action of external tensile stress or compressive stress, the overall extension direction of the crack 120 is basically perpendicular to the stress direction. Even if the overall extension path of the crack 120 has a certain degree of bending, the degree of bending is not large, and the width of each area of ​​the crack 120 is basically the same. By setting the size of the patrol guide 530 according to the actual working conditions, the patrol guide 530 can be stably adapted to the crack 120, and therefore it will not affect the transverse drive 510 to drive the patrol guide 530 to move along the extension path of the crack 120.

[0059] In the present invention, the positioning member 400 and the patrol guide member 530 are first used to position the two ends of the crack 120, so that the monitoring probe 540 is just above the crack 120, and then the patrol guide member 530 is driven to move along the extension path of the crack 120 through the cooperation of the transverse driving member 510 and the longitudinal moving member 520, thereby guiding the inspection path of the monitoring probe 540, so that the monitoring probe 540 is always above the crack 120, avoiding relative offset between the monitoring probe 540 and the crack 120 and affecting the accuracy of monitoring data collection.

[0060] In one embodiment, see Figure 6The frame 200 includes symmetrically distributed mounting platforms 210, the mounting platforms 210 on both sides are fixedly connected by a connecting frame 220, a mounting plate 230 is arranged in the middle of the connecting frame 220, and a rotating shaft 310 is arranged in the center of the swing frame 300, and the rotating shaft 310 is rotatably connected to the mounting plate 230;

[0061] See also Figure 8 The travel drive member 240 includes travel wheels 241 rotatably mounted below the mounting platforms 210 on both sides, and the travel wheels 241 on both sides are fixedly connected via a connecting shaft 242, wherein a travel motor 243 is mounted on one side of the mounting platform 210, and the travel motor 243 is transmission-connected to the connecting shaft 242 via a transmission belt 244;

[0062] Specifically, the connecting shaft 242 is driven to rotate by the travel motor 243, thereby driving the travel wheels 241 on both sides to move, so that the entire frame 200 can move forward along the reservoir dam 100;

[0063] In order to prevent the movement path of the entire frame 200 from being offset, dam body enclosures 110 are provided on both sides of the dam body of the reservoir dam 100, and the walking wheels 241 are in rolling contact with the upper end surface of the dam body enclosure 110 on the same side; recessed parts 111 are provided on both sides of the dam body enclosure 110, and positioning rollers 245 that are rollingly adapted to the recessed parts 111 are rotatably installed on the mounting platform 210;

[0064] Specifically, the positioning roller 245 is embedded in the corresponding recessed portion 111 of the dam body enclosure 110, so that the rack 200 can be positioned. The rack 200 is driven forward along the dam body by the walking wheel 241, and at the same time, the positioning roller 245 is driven to roll along the recessed portion 111 to prevent the moving path of the rack 200 from deviating and ensure the stability of the inspection route.

[0065] In yet another embodiment, see Fig. 9 The transverse driving member 510 includes a transverse guide rail 511 fixed on the swing frame 300, a transverse slider 512 slidably mounted on the transverse guide rail 511, a screw rod 513 rotatably mounted in the transverse guide rail 511, and a transverse motor 514 fixedly mounted on one end of the transverse guide rail 511;

[0066] The transverse motor 514 is used to drive the screw rod 513 to rotate, and the screw rod 513 is threadedly connected to the transverse slider 512; the longitudinal moving member 520 is arranged on the transverse slider 512.

[0067] For further information, see Fig.10The longitudinal moving member 520 includes a longitudinal moving guide rail 521 fixed on the transverse moving slider 512 and a longitudinal moving slider 522 slidably installed on the longitudinal moving guide rail 521; the longitudinal moving guide rail 521 is vertically distributed with the transverse moving guide rail 511; a longitudinal moving roller 523 that is rotatably installed on the longitudinal moving slider 522 and is rolling-compatible with the longitudinal moving guide rail 521; the patrol guide member 530 and the monitoring probe 540 are both arranged on the longitudinal moving slider 522.

[0068] Specifically, the lateral movement of the guide member 530 and the monitoring probe 540 can be realized by driving the screw rod 513 to rotate through the lateral movement motor 514, thereby driving the lateral movement slider 512 to slide along the lateral movement guide rail 511; during the lateral movement of the guide member 530 and the monitoring probe 540, since the second elastic probe 533 at the lower end of the guide member 530 is always located inside the crack 120, the guide member 530 can move forward along the curved extension path of the crack 120, and due to the limiting effect of the inner walls on both sides of the crack 120, the guide member 530 can drive the longitudinal movement slider 522 to slide adaptively on the longitudinal movement guide rail 521 according to the bending direction of the crack 120;

[0069] With the cooperation of the transverse driving member 510 and the longitudinal moving member 520, the patrol guide member 530 can move along the extension path of the crack 120. Since the monitoring probe 540 and the patrol guide member 530 remain relatively fixed, no matter where the monitoring probe 540 moves, the monitoring probe 540 is always located directly above the current area of ​​the crack 120, so that the crack 120 is always within the monitoring range of the monitoring probe 540, effectively avoiding the deviation of the monitoring probe 540 and the path of the crack 120.

[0070] Furthermore, when the rack 200 moves forward along the dam body of the reservoir dam 100, since the first elastic probe 430 and the second elastic probe 533 are always in contact with the upper end surface of the dam body, sliding friction is generated between the first elastic probe 430 and the second elastic probe 533 and the upper end surface of the dam body, which easily causes wear of the first elastic probe 430 and the second elastic probe 533 and increases the overall movement resistance of the rack 200;

[0071] Accordingly, see Fig.11 The fixed sleeve 410 has a first chamber 420 in which the first elastic probe 430 is slidably embedded. The first chamber 420 has a first spring 440 in contact with the first elastic probe 430. The first elastic probe 430 has a first ball 450 movably embedded in the lower end thereof.

[0072] Under the elastic force of the first spring 440, the first elastic probe 430 is always elastically extended, so that the first ball 450 is in rolling contact with the upper end surface of the dam body. When the rack 200 moves forward, the first ball 450 also rolls forward along the upper end surface of the dam body, thereby avoiding sliding friction between the first elastic probe 430 and the upper end surface of the dam body.

[0073] Likewise, see Fig.13 and Fig.14 The lower end of the telescopic sleeve rod 532 is provided with a second chamber 5321, the second elastic probe 533 is slidably embedded in the second chamber 5321, a second spring 5322 abutting against the second elastic probe 533 is arranged in the second chamber 5321, and a second ball 5331 is movably embedded in the lower end of the second elastic probe 533;

[0074] Under the elastic force of the second spring 5322, the second elastic probe 533 is always elastically extended, so that the second ball 5331 is in rolling contact with the upper end surface of the dam body. When the rack 200 moves forward, the second ball 5331 also rolls forward along the upper end surface of the dam body, thereby avoiding sliding friction between the second elastic probe 533 and the upper end surface of the dam body.

[0075] It is worth noting that no matter which of the first elastic probe 430 and the second elastic probe 533 enters the crack 120 first, the ball at the lower end of the other probe can make a circular motion with the probe that enters the crack 120 first as a circle, thereby driving the swing frame 300 to undergo adaptive deflection to ensure the smoothness of the positioning process.

[0076] In addition, after the monitoring and inspection of a crack 120 is completed, in order not to affect the continued forward movement of the rack 200, the first elastic probe 430 and the second elastic probe 533 need to be pulled out from the crack 120. This embodiment does not impose specific restrictions. For example, electromagnets can be installed in the first chamber 420 and the second chamber 5321 to magnetically attract the first elastic probe 430 and the second elastic probe 533, so that the first elastic probe 430 and the second elastic probe 533 are temporarily retracted, and the first elastic probe 430 and the second elastic probe 533 are released after they are completely offset from the crack 120, so that the first elastic probe 430 and the second elastic probe 533 can be reset again and abut against the upper end surface of the dam body.

[0077] In a further embodiment, considering that there are foreign objects such as weeds and gravel in the crack 120, when the patrol guide 530 moves forward along the crack 120 path, these foreign objects will affect the normal passage of the patrol guide 530, and the foreign objects filling the crack 120 will cause local distortion of the crack 120, affecting the accuracy of the monitoring probe 540 in obtaining the monitoring data of the crack 120; for this purpose, please refer to Fig.12 and Fig.13The upper end of the movable sleeve 531 is rotatably mounted on the longitudinal sliding block 522 through a rotating shaft 535, and a rotating motor 534 for driving the movable sleeve 531 is provided on the longitudinal sliding block 522; a plurality of sliding bars 5312 are vertically arranged in the movable sleeve 531, and the upper end of the telescopic sleeve rod 532 is slidably adapted to the sliding bars 5312, and a telescopic driving member for driving the telescopic sleeve rod 532 is provided on the longitudinal sliding block 522; a plurality of groups of telescopic plates 5323 are circumferentially arranged on the telescopic sleeve rod 532, and a flexible cleaning sheet 5326 is installed on the extended side of the telescopic plate 5323;

[0078] Specifically, after the second elastic probe 533 is inserted into the crack 120, the telescopic sleeve 532 is driven to extend from the movable sleeve 531 through the telescopic driving member, so that the telescopic sleeve 532 is also inserted into the crack 120. When the patrol guide 530 moves forward along the crack 120, the movable sleeve 531 and the telescopic sleeve 532 are driven to rotate synchronously by the rotating motor 534, which can drive the flexible cleaning sheet 5326 on the telescopic plate 5323 to clear foreign objects along the crack 120, so as to prevent foreign objects from blocking the normal passage of the patrol guide 530. At the same time, the complete outline of the crack 120 is completely exposed, which is conducive to improving the authenticity of the data of the crack 120 obtained by the monitoring probe 540.

[0079] Further, considering that after the crack 120 is monitored, in order to avoid affecting the normal movement of the rack 200, the telescopic sleeve 532 needs to be retracted into the movable sleeve 531. The telescopic drive member in this embodiment uses a pneumatic method to drive the telescopic sleeve 532 to perform telescopic movement. However, if an external air pipe is directly connected to the movable sleeve 531, when cleaning foreign objects in the crack 120, the movable sleeve 531 is always rotating, which may cause the external air pipe to be twisted, knotted or even broken. For this reason, please refer to Fig.13 and Fig.15 The telescopic driving member includes a casing 536 fixed on the longitudinal sliding block 522, the movable sleeve 531 is rotatably connected to the casing 536, a sealing ring 537 is provided at the rotatable connection between the casing 536 and the movable sleeve 531, an air pump 538 is installed on the longitudinal sliding block 522, an air pipe 539 is connected between the air pump 538 and the casing 536, and a vent hole 5311 connected to the inside of the casing 536 is opened on the side wall of the movable sleeve 531;

[0080] Specifically, when the telescopic sleeve 532 needs to be pushed out from the movable sleeve 531, the air pump 538 blows air into the sleeve 536 through the air pipe 539, and then the air in the sleeve 536 enters the movable sleeve 531 through the vent hole 5311, thereby increasing the air pressure in the movable sleeve 531 to push the telescopic sleeve 532 downward;

[0081] When the telescopic rod 532 needs to be retracted into the movable sleeve 531 , the air pump 538 draws air to the outside through the air pipe 539 , so that the air in the movable sleeve 531 is sucked out, and negative pressure is generated in the movable sleeve 531 , so that the telescopic rod 532 can be sucked back into the movable sleeve 531 .

[0082] It is noteworthy that since the movable sleeve 531 and the sleeve shell 536 are rotationally sealed and connected, and the interior of the movable sleeve 531 is always connected to the interior of the sleeve shell 536 through the vent hole 5311, no matter whether the movable sleeve 531 rotates or not, it will not affect the normal and continuous circulation of air, thereby ensuring the stability of the telescopic movement of the telescopic sleeve rod 532 and preventing the external air pipe from twisting and tangling.

[0083] Furthermore, when cleaning foreign matter in the crack 120, the telescopic plate 5323 needs to be radially extended from the telescopic sleeve 532, thereby expanding the cleaning radius of the flexible cleaning sheet 5326. In the process of the telescopic sleeve 532 retracting into the movable sleeve 531, the telescopic plate 5323 needs to be radially retracted into the telescopic sleeve 532 to avoid affecting the retraction of the telescopic sleeve 532 into the movable sleeve 531. For this purpose, please refer to Fig.13 and Fig.16 The telescopic sleeve 532 has a third chamber 5327 at its upper end, a piston disc 5328 is slidably disposed in the third chamber 5327, an air bag 53210 communicating with the third chamber 5327 is disposed in the telescopic sleeve 532, and a third spring 5329 abutting against the piston disc 5328 is disposed at one end of the third chamber 5327 away from the air bag 53210;

[0084] The telescopic plate 5323 is radially slidably embedded in the telescopic sleeve rod 532. A squeezing plate 5325 that fits with the airbag 53210 is provided on one side of the telescopic plate 5323 away from the flexible cleaning sheet 5326. A wedge-shaped surface 5324 is provided on the upper end of the telescopic plate 5323.

[0085] Specifically, when the telescopic sleeve 532 is retracted into the movable sleeve 531, the wedge-shaped surface 5324 at the upper end of the telescopic plate 5323 contacts the lower end of the movable sleeve 531. Since the wedge-shaped surface 5324 is squeezed by the movable sleeve 531, a radial thrust is applied to the telescopic plate 5323, so that the telescopic plate 5323 is forced to retract into the telescopic sleeve 532, so as to achieve the storage of the telescopic plate 5323; when the telescopic plate 5323 is radially retracted, the squeezing plate 5325 squeezes the airbag 53210 to contract, so that the gas of the squeezing airbag 53210 enters the space below the piston disc 5328 in the third chamber 5327, resulting in an increase in the air pressure in the space below the piston disc 5328, thereby pushing the piston disc 5328 to move upward, driving the third spring 5329 to compress;

[0086] When the telescopic sleeve rod 532 is pushed out again until the telescopic plate 5323 is completely separated from the movable sleeve 531, the third spring 5329 pushes the piston disk 5328 to move downward, so that the gas in the space below the piston disk 5328 in the third chamber 5327 enters the airbag 53210, causing the airbag 53210 to expand, and then radially pushes the telescopic plates 5323 around to extend radially, so as to realize the automatic pop-up of the telescopic plates 5323.

[0087] See also Fig.13 and Fig.17 The lower end of the movable sleeve 531 is also provided with an air nozzle 5313, and a one-way valve 5314 is installed at the connection between the air nozzle 5313 and the movable sleeve 531;

[0088] When the telescopic sleeve 532 is fully extended, the upper end of the telescopic sleeve 532 is located below the one-way valve 5314. At this time, the one-way valve 5314 is unidirectional, so that the air in the movable sleeve 531 is ejected from the air nozzle 5313; when the telescopic sleeve 532 is retracted, the one-way valve 5314 is closed;

[0089] Specifically, the telescopic sleeve 532 is driven by the air pump 538 to extend from the movable sleeve 531. When the telescopic sleeve 532 is fully extended, the air pump 538 continues to blow air into the movable sleeve 531, and the one-way valve 5314 opens in one direction. The excess air in the movable sleeve 531 can be ejected from the air nozzle 5313 through the one-way valve 5314, and the air nozzle 5313 can rotate synchronously with the movable sleeve 531, so that the air flow ejected by the circumferentially rotating air nozzle 5313 is used to blow and clean the crack 120 passed by the patrol guide 530, so as to prevent foreign matter swept out by the flexible cleaning sheet 5326 from being retained around the crack 120 and affecting the normal monitoring of the crack 120.

[0090] In addition, considering that the entire video monitoring device needs to move back and forth along the dam body of the reservoir dam 100 to monitor the crack 120, and the video monitoring process is continuous and dynamic, for the power supply and communication of each component in the video monitoring device, the traditional method of laying cables not only needs to be used with a drag chain to wrap the cables, but also the rack 200 is prone to breakage during the back and forth movement. For this reason, solar energy is used as the power supply source of the video monitoring device in this embodiment. For details, please refer to Figure 6A power supply unit 600 is provided on the frame 200, and the power supply unit 600 includes a battery pack 610 for power supply and a solar panel 620 electrically connected to the battery pack 610; the solar panel 620 converts light energy into electrical energy and stores it in the battery pack 610, and the battery pack 610 can provide electrical energy for the walking motor 243, the lateral movement motor 514, the rotating motor 534, the air pump 538 and the monitoring probe 540; of course, the above-mentioned complete solar power supply system also includes components such as a solar charge and discharge controller, an inverter and a power management module, which belong to the prior art in this field and will not be described in detail.

[0091] The specific implementation methods of this embodiment are described above, but this embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms inspired by this embodiment, all of which are within the protection of this embodiment.
