Description

Technical Field

[0001] This utility model relates to the field of hydrological detection technology, specifically to a water depth measurement device based on an unmanned aerial vehicle (UAV). Background Technology

[0002] The conventional method for measuring water depth is to use sonar from a vessel. This method is cumbersome, requiring a person to navigate the vessel to the designated area before using sonar for depth measurement. Currently, there are also technologies that use small unmanned vessels carrying sonar for depth measurement. However, these small unmanned vessels are prone to significant swaying with the waves, making measurement difficult. There are also methods that use drones to carry sonar devices to measure water depth, but drones are also easily affected by surface air currents, causing the sonar device to sway significantly, making sonar measurement difficult and failing to meet user needs. Utility Model Content

[0003] To address the aforementioned technical problems, a water depth measurement device based on unmanned aerial vehicles (UAVs) is provided, which solves the technical problem in the prior art where the shaking of unmanned vessels or UAVs makes sonar depth measurement operations difficult.

[0012] The following detailed explanation illustrates the specific implementation methods: like Figures 1 to 3 As shown: A water depth measurement device based on a drone includes a drone body 1 and a thrower 2. The thrower 2 is installed at the bottom of the drone body 1. Both the drone body 1 and the thrower 2 are existing mature technologies and will not be described in detail here. The device also includes a depth measuring component 3, which is installed at the thrower 2. The thrower 2 can throw the depth measuring component 3 into the water body, and the depth measuring component 3 can then measure the water depth. The depth measuring component 3 includes a suspension module and a detection module. The suspension module includes a floating mechanism and a sinking mechanism. The floating mechanism can float on the water surface, and the sinking mechanism can sink. The sinking mechanism and the floating mechanism are flexibly connected by a second connecting cable 39, so that the sinking mechanism is suspended in the water body. The depth measuring module is installed at the sinking mechanism for detecting water depth. The floating mechanism includes a floating platform 31 and a floating chamber 33. A connecting screw sleeve 32 is provided at the bottom of the floating platform 31. The outer side wall of the connecting screw sleeve 32 is provided with external threads. The connecting screw sleeve 32 is screwed into the top of the floating chamber 33 by the threads, so that the floating platform 31 and the floating chamber 33 can be disassembled and reassembled. The floating chamber 33 is a hollow structure. A through hole is opened in the middle of the floating platform 31. The through hole is used for threading a cable. A first connecting cable 34 passes through the through hole. A limit block 35 is provided at one end of the first connecting cable 34 inside the floating chamber 33. The other end of the first connecting cable 34 is fixedly connected to the UAV body 1. The first connecting cable 34 can be stored in the hollow cavity of the floating chamber 33. The limit block 35 can prevent the connecting cable from separating from the floating platform 31. The sinking mechanism includes a mounting sleeve 36, a mounting base 38, and a counterweight base 310. The mounting sleeve 36 is provided on the top of the mounting base 38. The top of the mounting base 38 is connected to the bottom of the float 33 by a second connecting cable 39. The second connecting cable 39 allows the sinking mechanism to be flexibly connected to the floating mechanism. The float 33 is adapted to the mounting sleeve 36 and is detachably embedded in the mounting sleeve 36. When the depth measuring component 3 is deployed to the water body, the floating mechanism is suspended on the water surface. The float 33 and the mounting sleeve 36 separate from each other under the gravity of the sinking mechanism. The bottom of the float 33 separates from the mounting base 38. The space between the two is used to accommodate the second connecting cable 39. The counterweight base 310 is screwed onto the end of the mounting base 38 away from the mounting sleeve 36, so that the counterweight base 310 and the mounting base 38 can be separated from each other. The depth measuring module is installed in the counterweight base 310 to facilitate the depth measuring module to measure the water depth.

[0013] The depth measurement module is existing technology. The depth measurement module includes a controller 311, a built-in battery 312, and a sonar 313. The controller 311 includes a corresponding communication module, which enables the depth measurement data of the sonar 313 to be remotely transmitted back to the user through the communication module. The controller 311 is electrically connected to the built-in battery 312 and the sonar 313. The sonar 313 is installed at the end of the counterweight 310 away from the mounting base 38, so that the sonar 313 can face the bottom of the water to measure the depth of the water.

[0014] The counterweight 310 has a hemispherical structure at one end where the sonar 313 is installed.

[0015] Several drainage grooves 37 are provided on the side wall of the mounting sleeve 36 near the mounting base 38. When the depth measuring component 3 rises and is retracted, the drainage grooves 37 can drain the water in the mounting sleeve 36, thereby reducing the weight.

[0016] A sealing ring is provided between the mounting base 38 and the counterweight base 310 to reduce the possibility of water entering the depth sounding module.

[0017] The specific implementation process is as follows: When using this UAV-based water depth measurement device, the UAV body 1 is first flown to a predetermined height above the water surface. Then, the launcher 2 is activated to drop the depth measuring component 3 onto the water surface. During the descent of the depth measuring component 3, the first connecting cable 34 is pulled out from the through hole in the middle of the floating platform 31. Then, the depth measuring module falls to the water surface. The height position of the UAV body 1 makes the first connecting cable 34 loose, so as to avoid the shaking of the UAV body 1 from affecting the depth measuring component 3. After the depth sounding component 3 falls to the water surface, the sinking mechanism, with its greater density and weight, begins to sink. Meanwhile, the floating mechanism, consisting of the floating platform 31 and the buoy 33, floats on the water surface. During the sinking process, the buoy 33 separates from the mounting sleeve 36 until the sinking mechanism reaches the position where the second connecting cable 39 is straightened. At this point, the sonar 313 of the depth sounding module can measure the depth of the water. Since the floating mechanism and the sinking mechanism are connected by the second connecting cable 39, the second connecting cable 39 can effectively reduce the swaying of the sinking mechanism caused by the waves. At the same time, the weight of the counterweight 310 of the sinking mechanism can also reduce the swaying of the sinking mechanism, thereby enabling the depth sounding module at the sinking mechanism to stably measure the depth of the water.

[0018] When the depth sounding component 3 needs to be retrieved, simply fly the drone body 1 high so that the sinking mechanism is removed from the water surface. During this process, the water loaded in the mounting sleeve 36 can be discharged from the drainage channel 37, reducing the mounting weight of the drone body 1.

[0019] This drone-based water depth measurement device uses the drone body 1 and the thrower 2 to throw the measuring rope component to the predetermined water area. The depth measuring component 3 is flexibly connected to the drone body 1 via the first connecting cable 34, so that the depth measuring module is not affected by the shaking of the drone. The floating mechanism and the sinking mechanism of the depth measuring component 3 are flexibly connected via the second connecting cable 39, which can effectively reduce the shaking of the sinking mechanism caused by the floating mechanism shaking with the water surface. The detection module located at the sinking module can quickly and conveniently detect the depth of the water body, meeting the user's needs.
