Description

Technical Field

[0001] The invention belongs to the technical field of reservoir rainfall monitoring, and in particular relates to an automatic reservoir water and rainfall monitoring and reporting system. Background Art

[0002] At present, the reservoir water and rainfall monitoring system is suitable for water conservancy management departments to remotely monitor the real-time data of reservoir water level, rainfall, etc., and also supports remote image monitoring, providing accurate and timely on-site information to ensure the appropriate water storage and safe flood season of the reservoir.

[0003] When detecting rainfall, rainwater is generally received by a cylinder. The existing equipment is not convenient to block the top of the cylinder, which easily leads to more debris entering the cylinder. In response to the above technical problems, a Chinese patent with patent announcement number CN111983731B drives two horizontal axes to rotate through a driving mechanism when in use. The rotation of the two horizontal axes drives two arc plates to rotate, so as to facilitate blocking the top of the cylinder, thereby reducing the amount of debris entering the cylinder. However, when receiving rainwater, the arc plate cannot continue to block the opening of the cylinder. Therefore, in the process of collecting rainwater, large impurities such as leaves and branches from the outside are easy to enter the cylinder, resulting in abnormal volume of rainwater in the cylinder, resulting in inaccurate rainfall detection results. Summary of the invention

[0004] The purpose of the present invention is to provide a reservoir water and rainfall automatic monitoring and reporting system, aiming to solve the technical problem in the prior art that impurities easily enter the cylinder during rainwater collection, resulting in inaccurate rainfall detection results.

[0005] The present invention is implemented as follows: a reservoir water and rainfall automatic monitoring and reporting system comprises a vertical pole, a monitoring box, a horizontal plate, and a monitoring tube are fixedly installed on the vertical pole, and a water level meter and a camera are fixedly installed on the horizontal plate;

[0006] A coaxially arranged inner cylinder is fixedly installed in the monitoring cylinder, and the top of the inner cylinder is connected to the outside world. A cover plate for closing the top of the inner cylinder is arranged on the top of the monitoring cylinder, and a lifting ring is slidably installed in the inner cylinder, and a bracket is fixedly installed in the lifting ring. A filter plate is rotatably installed on the end of the bracket away from the lifting ring, and its side wall is in contact with the side wall of the inner cylinder when the filter plate is in a horizontal state. A power component for driving the lifting ring to move up and down is arranged in the monitoring cylinder, and a closing plate for closing the lower end of the inner cylinder is arranged at the bottom of the monitoring cylinder, and a pressure water level sensor located in the inner cylinder is fixedly installed on the closing plate, and a discharge groove is provided at the bottom of the monitoring cylinder.

[0007] Further technical solution: the cover is rotatably mounted on the top wall of the monitoring tube and one side surface of the cover is in sliding contact with the upper surface of the monitoring tube. A first rotating power component is fixedly installed in the monitoring tube to drive the cover to rotate, and the rotation axis of the cover is located outside the inner tube.

[0008] Further technical solution: A through groove is provided in the area of ​​the cover plate away from the rotation axis and in contact with the upper surface of the monitoring tube, and a liquid sensor is fixedly installed in the through groove.

[0009] Further technical solution: The monitoring tube is provided with mounting blocks located on both sides of the closing plate, the closing plate is rotatably installed on the mounting blocks through a mounting shaft, a guide column for guiding the movement of the mounting block is fixedly installed on the bottom of the monitoring tube, an elastic part is fixedly installed on the surface of the mounting block close to the bottom surface of the monitoring tube, and the end of the elastic part away from the mounting block is fixedly connected to the bottom surface of the monitoring tube.

[0010] Further technical solution: gears are fixedly installed on the end of one set of mounting shafts of the closing plate. When the closing plate moves downward, the gears engage with racks fixedly installed on the bottom surface of the monitoring tube. A limiting iron block is fixedly installed on another set of mounting shafts of the closing plate. The limiting iron block is in sliding contact with a limiting magnet ring fixedly installed on the side of the mounting block. A top block is fixedly installed on the closing plate.

[0011] Further technical solution: The power assembly includes a second rotating power component, which is fixedly installed in the monitoring tube. The second rotating power component drives the screw to rotate, and the screw drives the movable plate to move. The movable plate is fixedly connected to a power magnet ring slidably installed on the outer side of the inner tube, and the power magnet ring is magnetically attracted to a magnet block fixedly installed inside the lifting ring.

[0012] Further technical solution: A pressing plate is fixedly installed on the movable plate, and when the movable plate moves downward, the pressing plate contacts one group of mounting blocks and pushes the closing plate to move downward.

[0013] Further technical solution: a groove is provided in the middle of the surface where the cover plate contacts the monitoring tube, a mounting magnet ring is provided in the groove, a filter is fixedly installed in the mounting magnet ring, a magnetic structure for the mounting magnet ring to adsorb is provided on the cover plate, the outer diameter length of the mounting magnet ring is between the inner and outer diameters of the lifting ring, and when the lifting ring contacts the cover plate, the mounting magnet ring contacts and adsorbs the magnet block.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. When rainwater enters the inner tube, it is filtered through the filter plate to prevent large impurities such as leaves and dead branches from entering the bottom of the inner tube during the rainwater collection process, ensuring the accuracy of precipitation detection. After the rainfall detection is completed, the lifting ring is driven downward by the power component. After the lifting ring moves downward to the set position, the power component will push the closing plate downward. After the closing plate and the inner tube are no longer in contact, the rainwater can leave the inner tube. When the lifting ring moves downward, it can push the impurities adhering to the inner wall of the inner tube to move downward. When the lifting ring moves to the bottom of the inner tube, it stops moving. At this time, the impurities on the inner wall of the inner tube are pushed away from the inner tube, and then the impurities will follow the water flow and leave the inner tube, realizing the cleaning of impurities adhering to the inner wall of the inner tube, avoiding impurities occupying the volume in the inner tube, and further ensuring the accuracy of the rainfall detection results.

[0016] 2. After the closing plate drops a set distance, the gear will contact the rack. The closing plate continues to drop, and the gear and rack make the closing plate rotate to the set angle. When the closing plate rotates, the top block pushes the filter plate to rotate synchronously. Then, when the rainwater leaves the inner cylinder, the closing plate and the filter plate will rotate to an inclined state. At this time, a large amount of rainwater will flush the surface of the closing plate and the filter plate, thereby cleaning the closing plate and the filter plate, reducing the probability of impurities remaining on the closing plate and the filter plate, improving the cleanliness of the internal components of the inner cylinder, and further improving the accuracy of rainfall detection.

[0017] 3. After the rainfall detection is completed, the cover plate is reset to close the top of the inner cylinder. At this time, the lifting ring contacts the cover plate and the mounting magnet ring contacts and adsorbs the magnet. The force between the mounting magnet ring and the magnet is greater than the force between the mounting magnet ring and the cover plate. Then, the lifting ring moves downward, which drives the mounting magnet ring to move with it. The filtering capacity of the filter screen is due to the filtering capacity of the filter plate. At this time, the filter screen can close the top of the lifting ring. When the lifting ring moves downward, the filter screen pushes the impurities floating in the rainwater to move downward with the lifting ring, thereby avoiding some impurities in the rainwater and impurities filtered on the filter plate from passing over the lifting ring during the downward movement of the lifting ring, and avoiding the impurities in the rainwater from adhering to the inner wall of the inner cylinder during the rainwater discharge process, further improving the cleanliness of the inner cylinder and improving the accuracy of rainfall detection.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0029] like Figure 1-Figure 8 As shown, a reservoir water and rainfall automatic monitoring and reporting system provided by the present invention comprises a vertical pole 1, a monitoring box 2, a horizontal plate 3, and a monitoring tube 6 are fixedly installed on the vertical pole 1, and a water level meter 4 and a camera 5 are fixedly installed on the horizontal plate 3;

[0030] A coaxially arranged inner cylinder 14 is fixedly installed in the monitoring cylinder 6, and the top of the inner cylinder 14 is communicated with the outside. A cover plate 7 for closing the top of the inner cylinder 14 is arranged on the top of the monitoring cylinder 6. The cover plate 7 is rotatably installed on the top wall of the monitoring cylinder 6 and one side surface of the cover plate 7 is in sliding contact with the upper surface of the monitoring cylinder 6. A first rotating power member 10 that drives the cover plate 7 to rotate is fixedly installed in the monitoring cylinder 6. The rotation axis of the cover plate 7 is located on the outside of the inner cylinder 14. A through groove 8 is provided in the area of ​​the cover plate 7 away from its rotation axis and in contact with the upper surface of the monitoring cylinder 6. A liquid sensor is fixedly installed in the through groove 8. Sensor 9, a lifting ring 15 is slidably installed in the inner cylinder 14, a bracket 17 is fixedly installed in the lifting ring 15, a filter plate 18 is rotatably installed at the end of the bracket 17 away from the lifting ring 15, and its side wall is in contact with the side wall of the inner cylinder 14 when the filter plate 18 is in a horizontal state, a power component 19 for driving the lifting ring 15 to move up and down is arranged in the monitoring cylinder 6, a closing plate 21 for closing the lower end of the inner cylinder 14 is arranged at the bottom of the monitoring cylinder 6, a pressure water level sensor 22 located in the inner cylinder 14 is fixedly installed on the closing plate 21, and a discharge groove 13 is opened at the bottom of the monitoring cylinder 6.

[0031] In actual application of this embodiment, the vertical pole 1 is fixedly installed beside the reservoir, and the horizontal plate 3 is extended into the reservoir. The water level of the reservoir is detected by the water level meter 4, and the water surface state of the reservoir is photographed by the camera 5. The detection and shooting information are sent to the server through the monitoring box 2 for observation and record by the staff;

[0032] When it rains, rainwater entering the through groove 8 will gather in the through groove 8. When the liquid sensor 9 in the through groove 8 detects rainwater, the control unit will be used to make the first rotating power member 10 drive the cover plate 7 to rotate. The cover plate 7 stops after rotating 180 degrees. The cover plate 7 rotates in the horizontal plane. When the cover plate 7 rotates 180 degrees, the position of the through groove 8 on the cover plate 7 is no longer in contact with the top of the monitoring tube 6. At this time, the lower end of the through groove 8 is in an open state, and rainwater flows downward under the action of gravity. At this time, the cover plate 7 no longer blocks the inner tube 14, and rainwater can enter the inner tube 14. The water level height of the set time period in the inner tube 14 is detected by the pressure water level sensor 22, and then the precipitation is calculated. The precipitation information is sent to the server through the monitoring box 2 for observation and recording by the staff;

[0033] When rainwater enters the inner cylinder 14, it is filtered by the filter plate 18, thereby preventing large-volume impurities such as leaves and dead branches from entering the bottom of the inner cylinder 14 during the rainwater collection process, ensuring the accuracy of precipitation detection. After the detection is completed, the cover plate 7 is reset to the top of the closed inner cylinder 14, thereby preventing impurities from entering the inner cylinder 14 when not in use. At this time, the lifting ring 15 is driven downward by the power component 19. After the lifting ring 15 moves downward to the set position, the power component 19 will push the closing plate 21 to move downward, and the closing plate 21 is not in contact with the inner cylinder 14. After contact again, the rainwater can leave the inner cylinder 14, and then the rainwater will leave the monitoring cylinder 6 from the discharge groove 13. When the lifting ring 15 moves downward, it can push the impurities adhered to the inner wall of the inner cylinder 14 to move downward. When the lifting ring 15 moves to the bottom of the inner cylinder 14, it stops moving. At this time, the impurities on the inner wall of the inner cylinder 14 are pushed away from the inner cylinder 14, and then the impurities will follow the water flow and leave the inner cylinder 14, thereby cleaning the impurities adhered to the inner wall of the inner cylinder 14, avoiding impurities occupying the volume inside the inner cylinder 14, and ensuring the accuracy of the rainfall detection results.

[0034] In an example of this embodiment, the first rotating power component 10 is a first motor, and of course it can also be other components capable of outputting rotating power, such as a hydraulic motor, and the cover plate 7 is driven to rotate by the first motor.

[0035] like Figure 3-Figure 7 As shown, an automatic monitoring and reporting system for water and rainfall conditions in a reservoir provided by the present invention is provided with mounting blocks 23 located on both sides of a closing plate 21 in a monitoring tube 6, the closing plate 21 is rotatably mounted on the mounting blocks 23 via a mounting shaft, a guide column 24 for guiding the movement of the mounting block 23 is fixedly mounted on the bottom of the monitoring tube 6, an elastic member 25 is fixedly mounted on the surface of the mounting block 23 close to the bottom surface of the monitoring tube 6, and one end of the elastic member 25 away from the mounting block 23 is fixedly connected to the bottom surface of the monitoring tube 6.

[0036] Specifically, a gear 26 is fixedly installed on the end of one group of mounting shafts of the closing plate 21. When the closing plate 21 moves downward, the gear 26 engages with a rack 27 fixedly installed on the inner bottom surface of the monitoring tube 6. A limiting iron block 29 is fixedly installed on another group of mounting shafts of the closing plate 21. The limiting iron block 29 is in sliding contact with a limiting magnet ring 28 fixedly installed on the side of the mounting block 23. A top block 34 is fixedly installed on the closing plate 21.

[0037] Specifically, the power assembly 19 includes a second rotating power component 30, which is fixedly installed in the monitoring tube 6. The second rotating power component 30 drives the screw rod 31 to rotate, and the screw rod 31 drives the movable plate 32 to move. The movable plate 32 is fixedly connected to the power magnet ring 20 slidably installed on the outer side of the inner tube 14, and the power magnet ring 20 is magnetically attracted to the magnet block 16 fixedly installed inside the lifting ring 15.

[0038] Specifically, a pressing plate 33 is fixedly mounted on the movable plate 32 . When the movable plate 32 moves downward, the pressing plate 33 contacts one group of the mounting blocks 23 and pushes the closing plate 21 to move downward.

[0039] In actual application of this embodiment, in the initial state, the elastic member 25 is in a compressed state, the closing plate 21 contacts the lower surface of the inner cylinder 14 and closes the lower end of the inner cylinder 14, and the elastic member 25 is compressed to apply a thrust to the closing plate 21 to ensure that the lower end of the inner cylinder 14 is in a closed state;

[0040] When the measurement is completed and the rainwater in the inner cylinder 14 needs to be discharged, the second rotating power member 30 drives the screw rod 31 to rotate, and the screw rod 31 drives the power magnet ring 20 to move downward through the moving plate 32. The power magnet ring 20 moves downward and drives the lifting ring 15 to move downward synchronously through the magnet block 16. When the lifting ring 15 descends, it drives the filter plate 18 to move downward. When the filter plate 18 moves to contact with the top block 34, the pressing plate 33 contacts with the mounting block 23. At this time, the moving plate 32 continues to move downward and can push the mounting block 23 to move downward through the pressing plate 33, thereby making the closing plate 21 Move downward away from the inner cylinder 14. At this time, the rainwater in the inner cylinder 14 can leave through the gap between the closing plate 21 and the inner cylinder 14. When the lifting ring 15 moves downward, it can push the impurities adhering to the inner wall of the inner cylinder 14 to move downward. When the lifting ring 15 moves to the bottom of the inner cylinder 14, the moving plate 32 stops moving. At this time, the impurities on the inner wall of the inner cylinder 14 are pushed away from the inner cylinder 14. Then, the impurities will follow the water flow and leave the inner cylinder 14, so as to clean the impurities adhering to the inner wall of the inner cylinder 14, avoid the impurities occupying the volume in the inner cylinder 14, and ensure the accuracy of the rainfall detection result;

[0041] After the closing plate 21 descends a set distance so that there is a set distance between the filter plate 18 and the lower end of the inner cylinder 14, the gear 26 will contact the rack 27, and the closing plate 21 continues to descend. Under the action of the gear 26 and the rack 27, the closing plate 21 rotates a set angle, and the closing plate 21 rotates through the top block 34 to push the filter plate 18 to rotate synchronously, so that when the rainwater leaves the inner cylinder 14, the closing plate 21 and the filter plate 18 will rotate to an inclined state. Since the filter plate 18 is installed on the lifting ring 15 through the bracket 17, there is a certain distance between the plane where the filter plate 18 is located and the plane where the mounting ring 15 is located. Therefore, when the filter plate 18 leaves the inner cylinder 14 downward, it can be in a free rotation state, and the filter plate 18 and the mounting ring 15 are vertical. The space left in the vertical direction is enough for the filter plate 18 to rotate and tilt, and the rotation of the filter plate 18 is achieved by the gear 26 and the rack 27. The maximum rotation angle of the filter plate 18 can be adjusted by changing the number of teeth of the gear 26 and the rack 27, so that the lifting ring 15 will not hinder the inclination of the filter plate 18 and the closing plate 21. At this time, a large amount of rainwater will wash the surfaces of the closing plate 21 and the filter plate 18, thereby cleaning the closing plate 21 and the filter plate 18, reducing the probability of impurities remaining on the closing plate 21 and the filter plate 18, and thus improving the accuracy of rainfall detection. The rotation of the closing plate 21 is limited by the limiting iron block 29 and the limiting magnet ring 28, thereby preventing the closing plate 21 from rotating at will;

[0042] After the rainwater is drained, the movable plate 32 moves upward, and the closing plate 21 moves upward under the action of the elastic member 25. During the upward movement of the closing plate 21, it rotates to a horizontal state, and the filter plate 18 rotates to a horizontal state. As the movable plate 32 continues to rise, the closing plate 21 contacts the bottom of the inner tube 14 again, and stops moving when the lifting ring 15 moves to the top of the inner tube 14.

[0043] In an example of the present invention, the second rotating power component 30 is a second motor, and of course it can also be other components capable of outputting rotating power, such as a hydraulic motor, etc. The lifting ring 15 is driven to move up and down by the second motor.

[0044] like Figure 8 As shown, an automatic monitoring and reporting system for water and rainfall conditions in a reservoir provided by the present invention is provided with a groove in the middle of the surface where the cover plate 7 contacts the monitoring tube 6, a mounting magnet ring 11 is arranged in the groove, a filter screen 12 is fixedly installed in the mounting magnet ring 11, a magnetic structure for adsorbing the mounting magnet ring 11 is arranged on the cover plate 7, the outer diameter length of the mounting magnet ring 11 is between the inner and outer diameters of the lifting ring 15, and when the lifting ring 15 contacts the cover plate 7, the mounting magnet ring 11 contacts and adsorbs the magnet block 16.

[0045] When the present embodiment is actually applied, when the cover plate 7 is opened, the mounting magnet ring 11 moves with the cover plate 7. After the rainfall detection is completed, the cover plate 7 is reset to close the top of the inner cylinder 14. At this time, the lifting ring 15 contacts the cover plate 7 and the mounting magnet ring 11 contacts and adsorbs the magnet block 16. The acting force between the mounting magnet ring 11 and the magnet block 16 is greater than the acting force between the mounting magnet ring 11 and the cover plate 7. Then, the lifting ring 15 moves downward, which drives the mounting magnet ring 11 to move along. The filtering capacity of the filter screen 12 is due to the filtering capacity of the filter plate 18. At this time, the filter screen 12 can seal the top of the lifting ring 15. When the lifting ring 15 moves downward, the filter screen 12 pushes the impurities floating in the rainwater to move downward with the lifting ring 15, thereby preventing some impurities in the rainwater and the impurities filtered on the filter plate 18 from passing over the lifting ring 15 upward during the downward movement of the lifting ring 15, and preventing the impurities in the rainwater from adhering to the inner wall of the inner cylinder 14 during the rainwater discharge process, thereby further improving the cleanliness of the inner cylinder 14 and improving the accuracy of rainfall detection.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0047] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
