Description

Technical Field

[0001] This application relates to the technical field of accumulated water data collection, and in particular to a device for collecting urban waterlogging accumulated water data. Background Art

[0002] At present, urban physical examination is an important focus for promoting the high-quality transformation and development of urban construction. Through urban physical examination, accurately identifying the shortcomings and deficiencies in urban construction and development is an important starting point for implementing urban renewal actions, coordinating urban planning, construction, and management, and promoting the high-quality development of the urban living environment.

[0003] Urban waterlogging accumulated water is one of the key projects in urban physical examination. At the present stage, the judgment of waterlogging accumulated water generally needs to be combined with the area and depth of the accumulated water to distinguish.

[0004] However, for the existing area of accumulated water, it is generally collected by shooting with a drone. The depth of the accumulated water cannot be collected by the drone and often requires manual entry into the accumulated water area for manual measurement. Due to the complex situation in the accumulated water area, there are safety hazards in manual measurement. Utility Model Content

[0005] In order to improve the problem of safety hazards in manual measurement of the depth of accumulated water, this application provides a device for collecting urban waterlogging accumulated water data.

[0006] This application provides a device for collecting urban waterlogging accumulated water data, adopting the following technical solution:

[0007] A device for collecting urban waterlogging accumulated water data, comprising a drone, a camera installed on the drone, and a water depth measuring mechanism. The water depth measuring mechanism includes a measuring ruler vertically fixed at the lower end of the drone. The measuring ruler is sleeved with an indicating float moving along the scale direction of the measuring ruler. The water depth measuring mechanism further includes a locking component for locking the position of the indicating float when the measuring ruler touches the bottom of the accumulated water.

[0008] By adopting the above technical solution, this data collection device integrates a drone, a camera, and a water depth measuring mechanism, realizing aerial shooting of the area of the accumulated water area and automatically measuring the depth of the accumulated water through the water depth measuring mechanism without the need for manual entry into the accumulated water area, greatly improving safety and efficiency. The indicating float moves as the water level rises. When the measuring ruler touches the ground, the locking component quickly fixes the position of the indicating float to ensure measurement accuracy.

[0009] Optionally, one end of the measuring ruler is fixed with a base, and a docking platform is provided at the lower end of the drone. The base is fixedly connected to the docking platform by bolts.

[0010] By adopting the above technical solution, through the bolt connection design of the base and the docking platform, the water depth measuring mechanism can be stably installed under the drone, facilitating quick installation and disassembly.

[0011] Optionally, the locking assembly includes a movable rod and a magic tape. An activity groove extending along the length direction is formed at one end of the measuring ruler far away from the drone. The movable rod is slidably connected in the activity groove. A connection hole extending along the length direction of the measuring ruler is formed on the outer side wall of the measuring ruler. A limiting groove extending along the length direction of the movable rod is formed on the movable rod. A limiting block is fixedly arranged on the inner wall of the indicating float. The limiting block passes through the connection hole and enters the limiting groove. The magic tape includes a fuzzy surface and a hook surface. The fuzzy surface and the hook surface are respectively fixed on the limiting block and the hole wall of the connection hole. The magic tape on the hole wall of the connection hole extends along the length direction of the connection hole. The locking assembly further includes a pushing member that, when the measuring ruler touches the bottom of the accumulated water, pushes the magic tape of the limiting block to be adhesively bonded to the magic tape on the hole wall of the connection hole.

[0012] By adopting the above technical solution, through the ingenious combination of the movable rod, the magic tape and the pushing member, the precise locking of the position of the indicating float is realized. The quick adhesive property of the magic tape ensures the high efficiency and reliability of the locking.

[0013] Optionally, the pushing member includes a guiding column fixed on the side wall of the movable rod. A guiding groove is formed on the inner wall of the measuring ruler. The guiding groove extends spirally along the length direction of the measuring ruler. The guiding column is located in the guiding groove. When the guiding column is located at one end of the guiding groove far away from the drone, one end of the movable rod extends out of the bottom of the measuring ruler. When the guiding column is located at one end of the guiding groove close to the drone, the movable rod is completely retracted into the measuring ruler, and the movable rod rotates to make the magic tape on the limiting block be adhesively bonded and fixed to the opposite hole wall of the connection hole.

[0014] By adopting the above technical solution, the spiral design of the guiding column and the guiding groove enables the movable rod to automatically expand and contract during rotation and trigger the adhesion of the magic tape, realizing an automatic locking process.

[0015] Optionally, the guiding groove penetrates through the side wall of the measuring ruler, and the guiding column is threadedly connected to the movable rod.

[0016] Optionally, the pushing member further includes a spring installed in the activity groove. One end of the spring abuts against the bottom of the activity groove, and the other end abuts against the movable rod. The elastic force provided when the spring is compressed is less than the adhesion strength between the fuzzy surface and the hook surface of the magic tape.

[0017] By adopting the above technical solution, the addition of the spring provides a restoring force for the movable rod, ensuring that the movable rod can automatically return to the initial position when there is no external force. At the same time, the elastic force of the spring is less than the adhesion strength of the magic tape, ensuring the stability after locking.

[0018] Optionally, the measuring ruler is of a cylindrical structure, and a notch extending along the length direction is cut on one side of the measuring ruler, and the scale of the measuring ruler is distributed on the notch.

[0019] By adopting the above technical solution, the cylindrical structure of the measuring ruler and the opening of the notch make the scale more clearly visible. This design also reduces the volume and weight of the measuring ruler, facilitating the carrying of the drone.

[0020] Optionally, the end of the movable rod extending out of the movable groove is of a chamfered structure.

[0021] By adopting the above technical solution, the chamfered design of the extending end of the movable rod reduces the resistance when contacting the bottom of the accumulated water.

[0022] In summary, the present application includes at least one of the following beneficial effects:

[0023] 1. Since the present invention uses a drone to carry a water depth measuring mechanism, there is no need for manual on-site measurement, improving the efficiency and safety of data collection.

[0024] 2. In the present invention, a locking component and a pushing member are preferably adopted to realize the automatic locking of the indicating buoy, ensuring the accuracy of data collection. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following further elaborates on this application in conjunction with the attached drawings.

[0038] The embodiment of this application discloses a device for collecting urban waterlogging and ponding data.

[0039] Refer to Figure 1 , 2 , the device for collecting urban waterlogging and ponding data includes a drone 1, a camera 2, and a water depth measurement mechanism 3. The camera 2 and the water depth measurement mechanism 3 are both fixedly installed at the bottom of the drone 1, one for taking pictures of the ponding area and the other for measuring the water depth of the ponding.

[0040] Refer to Figure 2 , 3 , the water depth measurement mechanism 3 includes a measuring ruler 31 and an indicator float 32. One end of the measuring ruler 31 is fixed with a base 311, and a docking platform 11 is arranged at the lower end of the drone 1. The base 311 of the measuring ruler 31 is fixedly connected to the docking platform 11 through bolts, realizing the detachable fixed connection between the measuring ruler 31 and the drone 1.

[0041] Refer to Figure 3 , the indicator float 32 is sleeved on the measuring ruler 31 and can move along the scale direction of the measuring ruler 31. The indicator float 32 is made of buoyant material, such as closed plastic foam, to ensure that it can float on the water surface. When the measuring ruler 31 touches the bottom of the ponding, the water depth measurement mechanism 3 further includes a locking assembly 33 for locking the position of the indicator float 32.

[0042] When implementing data collection, the drone 1 carries the water depth measurement mechanism 3 and flies above the ponding area, slowly descending to make the measuring ruler 31 touch the water surface. As the measuring ruler 31 descends, the indicator float 32 will float upward along the measuring ruler 31 until the measuring ruler 31 touches the bottom. At this time, the locking assembly 33 locks the indicator float 32 in the current position, captures the scale information on the measuring ruler 31 through the position of the indicator float 32, and thus determines the water depth.

[0043] Refer to Figure 3 ,4 The locking assembly 33 includes a movable rod 331 and a magic tape 332. An activity groove 312 extending along the length direction is formed at one end of the measuring ruler 31 away from the drone 1. The movable rod 331 can slide freely in the activity groove 312, and the end of the movable rod 331 away from the drone 1 has a chamfered structure. A connecting hole 313 extending along the length direction is arranged on the outer side wall of the measuring ruler 31, and the connecting hole 313 communicates with the activity groove 312. A limiting groove 3311 extending along the length direction is also arranged on the movable rod 331. A limiting block 321 is fixed on the inner wall of the indicating float 32, and the limiting block 321 passes through the connecting hole 313 and extends into the limiting groove 3311. The width of the connecting hole 313 is greater than that of the limiting block 321, which enables the limiting block 321 to move circumferentially within the connecting hole 313; the size of the limiting groove 3311 is adapted to the limiting block 321, and the limiting block 321 can only move along the length direction of the limiting groove 3311.

[0044] Refer to Figure 4 As shown, the magic tape 332 includes a mating fuzzy surface and a hook surface, where the fuzzy surface is fixed on the limiting block 321, and the hook surface is fixed on the hole wall of the connecting hole 313 and extends along the length direction of the connecting hole 313. The locking assembly 33 further includes a pushing member. When the measuring ruler 31 probes the bottom of the accumulated water, the pushing member will push the movable rod 331, so that the fuzzy surface of the magic tape 332 on the limiting block 321 adheres to the hook surface of the magic tape 332 on the hole wall of the connecting hole 313, thereby locking the position of the indicating float 32 and providing an accurate reference for the subsequent water depth data reading.

[0045] Refer to Figure 3 、 5 As shown, the pushing member includes a guiding column 3312. The guiding column 3312 is fixed on the side wall of the movable rod 331. A guiding groove 314 is formed on the inner wall of the measuring ruler 31, and the guiding groove 314 spirally extends along the length direction of the measuring ruler 31. One end of the guiding column 3312 extends into the guiding groove 314 and always moves along the track of the guiding groove 314. When the guiding column 3312 moves in the guiding groove 314, it can drive the movable rod 331 to rotate and expand and contract.

[0046] For the convenience of installing the guiding column 3312, the guiding column 3312 and the movable rod 331 are fixed by threaded connection, and the guiding groove 314 penetrates the inner wall of the measuring ruler 31, so that the guiding column 3312 can pass through the measuring ruler 31 and be threadedly connected with the movable rod 331.

[0047] When the guide post 3312 is located at the end of the guide groove 314 away from the drone 1, one end of the movable rod 331 will extend out of the bottom of the measuring scale 31, facilitating the setting and inspection of the initial state; when the guide post 3312 moves to the end of the guide groove 314 close to the drone 1, the movable rod 331 will be completely retracted into the measuring scale 31, and the magic tape 332 on the limiting block 321 will be adhered to the magic tape 332 on the wall of the connecting hole 313 opposite thereto by rotation to achieve locking.

[0048] It should be emphasized here that without external force, the movable rod 331 will extend out of the movable groove 312 under the action of its own gravity, and the guide post 3312 will naturally move to the end of the guide groove 314 away from the drone 1.

[0049] Refer to Figure 3 , the pusher further includes a spring 333 installed in the movable groove 312. One end of the spring 333 is in contact with the bottom of the movable groove 312, and the other end is in contact with the movable rod 331. When the measuring scale 31 touches the bottom, the spring 333 will be compressed by force, applying a thrust to the movable rod 331 in the direction away from the drone 1. However, this thrust is designed to be less than the adhesion strength between the rough surface and the hook surface of the magic tape 332 to ensure that the magic tape 332 will not automatically separate under the push of the spring 333, thereby ensuring that the indicating float 32 can be firmly locked on the measuring scale 31.

[0050] Refer to Figure 4 , the measuring scale 31 is a cylindrical structure. A notch 315 is cut out along the length direction on one side of the measuring scale 31, and the scale of the measuring scale 31 is distributed on this notch 315.

[0051] In this embodiment, the scale of the measuring scale 31 has a maximum water level value. When the indicating float 32 floats to the maximum water level value and the movable rod 331 has not touched the bottom, it indicates that there is indeed water accumulation at this place.

[0052] The implementation principle of a device for collecting urban waterlogging accumulation data in an embodiment of the present application is as follows:

[0053] When implementing data collection, the unmanned aerial vehicle 1 carries the water depth measuring mechanism 3 and flies above the water accumulation area, slowly descending to make the measuring ruler 31 touch and extend into the water. As the measuring ruler 31 descends, the indicating float 32 will float upward along the measuring ruler 31 until the measuring ruler 31 touches the bottom. At this time, one end of the movable rod 331 is squeezed and contracted into the movable groove 312, and by means of the way that the guiding column 3312 moves and rotates along the guiding groove 314, the magic tape 332 on the indicating float 32 is adhered to the magic tape 332 on the wall of the connecting hole 313, so as to be locked in the current position. The unmanned aerial vehicle 1 then ascends and captures the scale on the measuring ruler 31 and the position information of the indicating float 32 through the camera 2, so as to remotely determine the water depth. Or control the unmanned aerial vehicle 1 to fly back for scale recording.

[0054] The above are all preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of this application shall be covered within the protection scope of this application.
