Description

Technical Field

[0001] This invention relates to the technical field of water conservancy engineering, specifically to a smart water conservancy engineering inspection and patrol method. Background Technology

[0002] With the development of technology and people's increasing attention to water resources, smart water conservancy projects are important projects for people's livelihood and an important part of smart cities. Among them, water environment protection is an important project for people's livelihood in smart water conservancy projects. However, there are often floating objects in existing reservoirs or rivers. These floating objects are either garbage discarded by humans, or organic matter such as tree branches and leaves and aquatic plants floating with the water flow. As these floating objects are soaked in the water for a long time, they will rot and pollute the water, seriously affecting the water quality.

[0003] As disclosed in the invention with announcement number CN115493888B, a smart water conservancy project inspection and monitoring device, after receiving a control command from a wireless remote sensing signal receiver, has its CPU, located inside the main body of the drone inspection and monitoring device, drive and control an electric telescopic rod. This causes the telescopic rod to extend outward, and the electric telescopic rod, through a connecting gasket, pushes the inner tube of the rigid telescopic water-drawing pipe to move outward along the middle pipe wall. The middle pipe then slides outward along the outer pipe wall, extending the length of the rigid telescopic water-drawing pipe. This allows it to reach deeper water layers for water quality sampling. After sampling, the electric telescopic rod resets, returning the rigid telescopic water-drawing pipe to its initial position for the next sampling, thus enabling sampling and testing of deeper river water.

[0004] However, the device can only sample water sources and is not effective at handling floating debris on the water surface.

[0005] Traditional methods involve setting up nets or dams to capture floating debris at the entrances and exits of rivers or reservoirs. However, these methods can only intercept floating debris when there is a water flow caused by a height difference. They cannot intercept floating debris on calm surfaces such as lakes, causing the debris to float in the water for a long time and affecting water quality.

[0006] Therefore, we propose a smart water conservancy project inspection and patrol method to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide a smart water conservancy project inspection method. By setting up a driving mechanism, the capture frame is driven to put the floating objects it collects into a collection box. When the capture frame pours the floating objects into the collection box, some floating objects will stick to the inner wall of the capture frame.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. Example 1:

[0024] Please see Figures 1-5 This invention provides a technical solution: a smart water conservancy project inspection and patrol method, comprising the following steps: S1. Clean up floating objects: Use a salvage device to salvage floating objects on the water surface; S2, Tapping the capture frame: The tapping mechanism 5 taps the capture frame 2 to shake some floating objects stuck to the inner wall of the capture frame 2 into the collection box 3; S3. Water sample collection: The sampling mechanism 6 enables the device to collect water samples from different depths. The salvage device includes a drone 1 for patrol, a capture frame 2 with one open side for salvaging floating objects on the water surface and a collection box 3 for loading floating objects, and a drive mechanism 4 for driving the capture frame 2 to put the salvaged floating objects into the collection box 3.

[0025] A camera and a distance sensor are fixedly installed on the lower surface of the drone 1.

[0026] When in use, staff can drive the drone 1 to fly above the water surface through an external wireless remote control device. The camera installed on the drone 1 can clearly capture whether there are floating objects on the water surface. When a floating object is encountered, the entire salvage device moves close to the floating object and uses the capture frame 2 to salvage the floating object. When the entire salvage device is close to the water surface, the distance sensor can sense the distance between the entire device and the water surface.

[0027] The drive mechanism 4 includes two uprights 41 vertically fixed to the lower surface of the UAV 1. The lower ends of the two uprights 41 are jointly fixed to a rectangular plate 42. A drive rod 43 driven by an external drive device is rotatably connected to the surface of the rectangular plate 42. The drive rod 43 has a strip groove 44.

[0028] The external drive device is a motor.

[0029] A horizontal bar 45 is laterally slidably connected to the surface of the rectangular plate 42. A rectangular sleeve 46 is fixedly connected to one end of the horizontal bar 45. A rectangular rod 47 is telescopically inserted into the rectangular sleeve 46. The capture frame 2 is installed at the lower end of the rectangular rod 47. A round rod 48 is rotatably connected to the surface of the rectangular rod 47. A sliding strip 49 located in the strip groove 44 is fixedly connected to one end of the round rod 48. A cylindrical block 410 is vertically fixed to the side of the sliding strip 49 away from the round rod 48. An L-groove 411 for the cylindrical block 410 to slide is opened on the surface of the rectangular plate 42.

[0030] The L-groove 411 has interconnected horizontal and vertical grooves. In the initial state, the cylindrical block 410 is located at the bottom of the vertical groove of the L-groove 411, and the capture frame 2 is located at the lowest point, which can retrieve floating objects on the water surface. When the capture frame 2 retrieves the floating object, the motor is started to drive the drive rod 43 to swing to the free end of the horizontal groove of the L groove 411. The drive rod 43 can push the cylindrical block 410 to move upward along the L groove 411 to the limit position through the sliding bar 49, and then move horizontally to one end of the horizontal groove of the L groove 411. At the same time, the sliding bar 49 can drive the capture frame 2 to move upward to the limit position through the round rod 48 and the rectangular rod 47, and then move horizontally to the top of the collection box 3.

[0031] At the same time, the crossbar 45 can move horizontally.

[0032] The drive mechanism 4 also includes two mounting plates 412 that are vertically fixed to the upper surface of the capture frame 2. The two mounting plates 412 are rotatably connected to the lower end of the rectangular rod 47. A bevel gear 413 that is coaxially fixed to the two mounting plates 412 is provided above the capture frame 2. A horizontal plate 414 is vertically fixed to the side wall of the rectangular rod 47. A first gear 415 is rotatably connected to one end of the horizontal plate 414, and a second bevel gear 416 that is coaxially fixed to the first gear 415 and meshes with the first bevel gear 413.

[0033] Two extension rods 417 are vertically fixed to the surface of the rectangular plate 42, and the free ends of the two extension rods 417 are jointly fixed with a rack 418.

[0034] When the rectangular rod 47 moves upward to its limit position, the first gear 415 can mesh with the rack 418. When the rectangular rod 47 drives the first gear 415 to move horizontally towards the collection box 3 via the horizontal plate 414, the first gear 415 will rotate and drive the bevel gear 416 fixed to it on the same axis to rotate. The bevel gear 416 can drive the bevel gear 413 meshing with it to rotate. The bevel gear 413 can drive the two mounting plates 412 fixed to it on the same axis to rotate. The mounting plates 412 can drive the capture frame 2 to rotate, so that the open side of the capture frame 2 is aligned with the collection box 3, and the floating objects in the capture frame 2 are poured into the collection box 3. Example 2:

[0035] Please see Figures 6-8 This embodiment further illustrates Example 1, wherein a striking mechanism 5 for striking the capture frame 2 is provided below the drone 1.

[0036] When the capture frame 2 pours floating objects into the collection box 3, some floating objects will stick to the inner wall of the capture frame 2. By setting a knocking mechanism 5, the capture frame 2 can be knocked to shake some of the floating objects stuck to the inner wall of the capture frame 2 into the collection box 3.

[0037] The striking mechanism 5 includes a bearing seat 51 that is laterally limited and slidably connected to a rectangular plate 42. A side plate 52 is vertically fixed at the edge of the rectangular plate 42. A long rod 53 with one end passing through the side plate 52 is vertically fixed on one side of the surface of the bearing seat 51. A spring 54 sleeved on the surface of the long rod 53 is fixedly connected between the side plate 52 and the bearing seat 51.

[0038] A rectangular groove 55 is provided on the lower surface of the support seat 51. A movable block 56 extending to the outside of the rectangular groove 55 is provided in the rectangular groove 55. The movable block 56 is inclined on the side near the side plate 52 and slopes from top to bottom from the side near the side plate 52 to the side away from the side plate 52. A rod 57 is vertically fixed on the upper surface of the movable block 56. The upper end of the rod 57 passes through the support seat 51 and extends to the outside of the support seat 51. A spring 58 is fixedly connected between the movable block 56 and the inner wall of the rectangular groove 55 and sleeved on the surface of the rod 57.

[0039] The surface of the movable block 56 is rotatably connected to a push rod 59. The surface of the rectangular plate 42 is vertically fixed to a connecting rod 510. One end of the connecting rod 510 is vertically fixed to an inclined block 511. The inclined block 511 is inclined on the side away from the side plate 52, and slopes from top to bottom from the side close to the side plate 52 to the side away from the side plate 52. The surface of the crossbar 45 is vertically fixed to a drive column 512. The surface of the bearing seat 51 is fixedly connected to a bending rod 513.

[0040] When the crossbar 45 moves in the direction of arrow E, it can drive the drive column 512 fixed on its surface to move accordingly, so that the drive column 512 gradually contacts the movable block 56 and drives the movable block 56 to move in the direction of arrow E. The movable block 56 can drive the push rod 59 and the bearing seat 51 to move in the direction of arrow E, so that the bearing seat 51 presses against the spring 54. When push rod 59 contacts the inclined surface of inclined block 511, it will be restricted by inclined block 511 and move upward. Push rod 59 can drive movable block 56 to move upward, so that movable block 56 is separated from drive column 512. At this time, spring 54 can drive bearing seat 51 to move in the opposite direction of arrow E through rebound force. Bearing seat 51 can drive bent rod 513 fixed on its surface to move in the opposite direction of arrow E, so that the free end of bent rod 513 has an impact force on capture frame 2, causing capture frame 2 to vibrate and shake the floating objects in capture frame 2 into collection box 3.

[0041] When the horizontal bar 45 moves to its limit position in the direction of arrow E, the motor will drive the drive rod 43 to rotate in the opposite direction. The drive rod 43 can drive the cylindrical block 410 to move along the horizontal groove of the L groove 411 towards the side closer to the vertical groove through the sliding bar 49, until the cylindrical block 410 moves to the lower end of the vertical groove and returns to the initial position. At the same time, the sliding bar 49 can drive the rectangular rod 47 to move through the round rod 48. The rectangular rod 47 can drive the horizontal bar 45 to move in the opposite direction of arrow E through the rectangular sleeve 46. The crossbar 45 can drive the drive column 512 to move in the opposite direction of arrow E, so that the drive column 512 can gradually contact the inclined surface of the movable block 56 and push the movable block 56 upward, thus smoothly passing through the movable block 56 and returning to the initial position. Example 3:

[0042] Please see Figures 9-10 This embodiment further illustrates Example 2, wherein a sampling mechanism 6 is provided below the drone 1.

[0043] By setting up sampling mechanism 6, the device can sample water sources and obtain water samples at different depths.

[0044] The sampling mechanism 6 includes a sampling bucket 61 fixed on a rectangular plate 42. A sampling tube 62, which communicates with the inside of the sampling bucket 61, is fixedly connected to the surface of the sampling bucket 61. A water pump is installed on the sampling tube 62. An adjusting tube 63 is telescopically inserted into the lower end of the sampling tube 62.

[0045] The sampling mechanism 6 also includes a top plate 64 fixed to the surface of the rectangular plate 42. One end of the top plate 64 is rotatably connected to a threaded rod 65, and a bevel gear 66 is coaxially fixed below the threaded rod 65. The surface of the threaded rod 65 is fitted with an internal threaded sleeve 67 that is threadedly connected to it. A limiting rod 68 that passes through the internal threaded sleeve 67 is vertically fixed to the lower surface of the top plate 64. A linkage rod 69 is fixedly connected between the internal threaded sleeve 67 and the adjusting tube 63.

[0046] The rear surface of the rectangular plate 42 is rotatably connected to an annular shaft, with a ratchet 610 fixed on the inner ring and a bevel gear 611 meshing with a bevel gear 66 on the outer ring. The rear surface of the rectangular plate 42 is rotatably connected to a rectangular seat 612 coaxially fixed with the drive rod 43. A limiting rod 613 is telescopically inserted into the surface of the rectangular seat 612. A ratchet 614 meshing with the ratchet 610 is fixedly connected to the upper end of the limiting rod 613. A spring 615 sleeved on the surface of the limiting rod 613 is fixedly connected between the ratchet 614 and the rectangular seat 612.

[0047] In use, the starter motor drives the drive rod 43 to reciprocate. The drive rod 43 can drive the rectangular seat 612, which is fixed coaxially with it, to reciprocate. The rectangular seat 612 can drive the ratchet 614 to reciprocate through the limiting rod 613. However, the ratchet 614 can only drive the ratchet 610 to rotate in one direction, so that the ratchet 610 is in an intermittent unidirectional rotation state. The ratchet 610 can drive the bevel gear 611, which is fixed coaxially with it, to rotate in one direction intermittently. The bevel gear 611 can drive the bevel gear 66, which meshes with it, to rotate. The bevel gear 66 can drive the threaded rod 65, which is fixed coaxially with it, to rotate. The threaded rod 65 can drive the inner threaded sleeve 67 to move downward. The inner threaded sleeve 67 can drive the adjusting tube 63 to move downward through the limiting rod 68. When the distance between the drone 1 and the horizontal plane remains unchanged, the deeper the adjusting tube 63 moves downward, the deeper the water is drawn.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
