Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0038] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0039] Please see Figure 1 , Figure 2 and Figure 3 One embodiment of this application provides a circuit inspection drone 10, including a drone body 100, a mounting bracket 200, a plurality of lowering inspection mechanisms 300, a deployment mechanism 400, and a recovery mechanism 500. The mounting bracket 200 is disposed on the drone body 100. The plurality of lowering inspection mechanisms 300 are spaced apart on the mounting bracket 200 and are used to inspect submarine cables. The deployment mechanism 400 is disposed within the mounting bracket 200 and is used to deploy the plurality of lowering inspection mechanisms 300 to a designated deployment point. The recovery mechanism 500 is disposed on the deployment mechanism 400 and is used to recover the lowering inspection mechanisms 300 on the sea surface.

[0040] Please see Figure 1 , Figure 6 and Figure 7 The deployed inspection mechanism 300 includes a detection imaging module 310, a positioning module, and a buoyancy component 320. The detection imaging module 310 is used to acquire image information of the submarine cable to be inspected. The buoyancy component 320 is used to provide buoyancy for the deployed inspection mechanism 300 to move the deployed inspection mechanism 300 to the sea surface after the inspection is completed. The positioning module is communicatively connected to the UAV body 100. Specifically, the UAV body 100 includes a UAV control module, and the positioning module is communicatively connected to the UAV control module.

[0041] It is important to understand that the detection imaging module 310 can communicate with a control terminal to transmit the image information of the submarine cable to be inspected to the outside for real-time observation by maintenance personnel. Specifically, the detection imaging module 310 uses an infrared detector. The infrared detector uses infrared thermal imaging technology; more specifically, it uses a thermal infrared scanner to receive and record the thermal radiation energy emitted by the submarine cable to be inspected to form an image.

[0042] When inspection is required, the UAV 100 flies to the designated drop point and hovers above the sea surface. Using the drop mechanism 400, one of the drop inspection units 300 is deployed to the current designated drop point. The deployed inspection unit 300 inspects the submarine cable. Simultaneously, the UAV 100 takes off and repeats the above steps to deploy the other drop inspection unit 300 to the next designated drop point, allowing the other drop inspection unit 300 to inspect submarine cables at other locations in the sea. After the inspection is completed, the UAV 100 uses its positioning module to obtain the location of the completed drop inspection unit 300. The UAV 100 then flies to the airspace above the deployed inspection unit 300 and uses the recovery mechanism 500 to retrieve the deployed inspection unit 300 from the sea surface.

[0043] By configuring a drone body 100, several deployed inspection units 300, a deployment mechanism 400, and a recovery mechanism 500, the drone body 100 can fly to the airspace above a designated deployment point. The deployment mechanism 400 then deploys the deployed inspection units 300 to different designated deployment points to inspect submarine cables at different locations. This allows for wide-area inspection of submarine cables, improving inspection efficiency. Furthermore, by incorporating an imaging module 310, image information of the submarine cables to be inspected can be acquired, providing more accurate information. By setting up a buoyancy component 320, buoyancy can be provided to the lowered inspection mechanism 300 to bring the lowered inspection mechanism 300 to the sea surface after the inspection is completed; by setting up a positioning module, the lowered inspection mechanism 300 can be located, and the UAV body 100 can fly to the corresponding position according to the positioning information sent by the positioning module; by setting up a recovery mechanism 500, the lowered inspection mechanism 300 on the sea surface can be recovered. This application can improve the inspection efficiency of submarine cables, and can greatly save manpower and reduce the risks to inspection personnel.

[0044] The circuit inspection drone 10 of this application is described in detail below with reference to the accompanying drawings.

[0045] Please see Figure 1 , Figure 2 and Figure 3 According to some embodiments of this application, optionally, the mounting bracket 200 includes a first sealing housing 210 and a support platform 220. The first sealing housing 210 is connected to the UAV body 100. The support platform 220 is connected to the first sealing housing 210 via a first drive motor 230. Specifically, the first sealing housing 210 is connected to the bottom of the UAV body 100. The top of the first drive motor 230 is connected to the bottom of the first sealing housing 210. The support platform 220 is connected to the power output end of the first drive motor 230. The first drive motor 230 can drive the support platform 220 to rotate.

[0046] A plurality of sleeves 240 are provided on the support platform 220, and the sleeves 240 are angularly adjustable and connected to the support platform 220. In one embodiment, all of the sleeves 240 are angularly adjustable and connected to the support platform 220. In another embodiment, some of the sleeves 240 are angularly adjustable and connected to the support platform 220. Others of the sleeves 240 are fixedly connected to the support platform 220.

[0047] Specifically, the support platform 220 has multiple mounting holes, and the sleeve 240 is movably installed in these holes. A fourth drive motor 250 is also fixedly connected to the support platform 220, and the power output end of the fourth drive motor 250 is fixedly connected to the sleeve 240. Rotation of the fourth drive motor 250 drives the sleeve 240 to rotate, allowing adjustment of the sleeve 240's angle, thereby adjusting the downward deployment angle of the lowering inspection mechanism 300. Simultaneously, the first drive motor 230 can drive the support platform 220 to rotate, also allowing adjustment of the downward deployment angle of the lowering inspection mechanism 300.

[0048] Each sleeve 240 is fitted with a lowering inspection mechanism 300, which facilitates the lowering of the lowering inspection mechanism 300. During deployment, the lowering inspection mechanism 300 is separated from the sleeve 240.

[0049] Please see Figure 1 , Figure 2 , Figure 3 and Figure 8 According to some embodiments of this application, optionally, the lowering inspection mechanism 300 is sealed within the sleeve 240, and a sealed space is formed between the sleeve 240 and the lowering inspection mechanism 300. More specifically, a sealing ring 260 is connected between the lowering inspection mechanism 300 and the sleeve 240.

[0050] Please see Figure 1 , Figure 2 and Figure 4 The dispensing mechanism 400 includes a storage tank 410, a pumping assembly 420, and an air compressor 430. The pumping assembly 420 is used to pump seawater into the storage tank 410, and the air compressor 430 is used to discharge compressed air into the storage tank 410. The storage tank 410 is connected to a sealed space via a connecting pipe 440, and a solenoid valve is connected to the connecting pipe 440. The solenoid valve is used to control the opening and closing of the connection between the storage tank 410 and the sealed space.

[0051] Specifically, the pumping assembly 420 includes a pump 421, an inlet pipe 422, and an outlet pipe 423, with the pump 421 connected to both the inlet and outlet pipes. The inlet pipe 422 extends into seawater. The outlet pipe 423 is connected to a storage tank 410, and the pump 421 can pump seawater from the inlet pipe 422 into the storage tank 410.

[0052] When the UAV 100 flies to the designated drop point, seawater is pumped into the storage tank 410 via the pumping unit 420, and compressed air is discharged into the storage tank 410 via the air compressor 430. When drop is required, the control solenoid valve opens to connect the storage tank 410 with the sealed space. The seawater and compressed gas in the storage tank 410 are then quickly discharged into the sealed space, increasing the pressure within the sealed space and rapidly ejecting the drop inspection mechanism 300, allowing it to quickly enter the seawater.

[0053] Please see Figure 1 , Figure 5 and Figure 6 According to some embodiments of this application, optionally, the lowering inspection mechanism 300 further includes a second sealing housing 330 and an adjusting assembly 340. The second sealing housing 330 is connected inside the sleeve 240, and the detection imaging module 310, positioning module, and buoyancy assembly 320 are all connected to the second sealing housing 330. A depth detection module is also provided on the second sealing housing 330, which is communicatively connected to a control terminal, enabling the lowering inspection mechanism 300 to descend to a set position. Specifically, the second sealing housing 330 includes a cylindrical portion and a conical portion connected to the cylindrical portion.

[0054] The adjustment assembly 340 includes a plurality of support plates 341 arranged circumferentially along the second sealing housing 330 and a first propeller 342 connected to the support plates 341. The angle between the support plates 341 and the second sealing housing 330 is adjustable. Specifically, the support plates 341 are hinged to the end of the cylindrical portion near the conical portion. The detection imaging module 310 is located at the end of the conical portion away from the cylindrical portion.

[0055] Specifically, the adjustment assembly 340 includes a support drive unit 343, which is rotatably connected to the second sealing housing 330 and hinged to the support plate 341. Each support plate 341 is connected to a support drive unit 343. By driving the support drive unit 343, the angle of the support plate 341 relative to the second sealing housing 330 can be adjusted. More specifically, the support drive unit 343 is a cylinder.

[0056] It is important to understand that when all support plates 341 are in the deployed state, the resistance experienced by the second sealing shell 330 increases, which drives the first propeller 342 to rotate, thereby stopping the second sealing shell 330 from descending. Furthermore, by adjusting the angles between the multiple support plates 341 relative to the second sealing shell 330, and in conjunction with the first propeller 342, the position of the second sealing shell 330 can be adjusted so that it can detect the submarine cable at a predetermined location. When all support plates 341 are in the retracted state, the resistance experienced by the second sealing shell 330 decreases, allowing it to quickly reach the appropriate position.

[0057] Please see Figure 1 , Figure 5 , Figure 6 and Figure 7 According to some embodiments of this application, optionally, the lowering inspection mechanism 300 further includes a retracting mechanism 350. The retracting mechanism 350 includes a rotating shaft 351 disposed within the second sealing housing 330, a second drive motor 352 for driving the rotating shaft 351 to rotate, and a connecting line 353 wound around the rotating shaft 351. The connecting lines 353 between at least three second sealing housings 330 arranged sequentially along the support platform 220 are interconnected. Specifically, the retracting mechanism 350 is disposed in the cylindrical portion of the second sealing housing 330.

[0058] In this embodiment, several groups of inspection mechanisms are included, each group comprising three subordinate inspection mechanisms 300. One group of inspection mechanisms is deployed when the deployment mechanism 400 deploys. That is, the deployment mechanism 400 deploys three subordinate inspection mechanisms 300 each time. Specifically, the middle subordinate inspection mechanism 300 is equipped with two receiving mechanisms 350.

[0059] The three second sealing housings 330 simultaneously descend to the appropriate position. By driving the second drive motor 352 to rotate the shaft 351, the connecting wire 353 is retracted or extended, thereby adjusting the position between the second sealing housings 330, which can effectively improve inspection efficiency. Simultaneously, during retrieval, by driving the second drive motor 352 to rotate the shaft 351, the connecting wire 353 is tightened, collecting the three second sealing housings 330 together, facilitating retrieval by the retrieval mechanism 500.

[0060] Please see Figure 1 , Figure 6 and Figure 7 According to some embodiments of this application, optionally, the buoyancy component 320 includes a compression tank 321 disposed in the second sealed housing 330 and an airbag 322 connected to the top of the second sealed housing 330. The compression tank 321 is connected to the airbag 322, and the compression tank 321 stores compressed gas.

[0061] After the inspection is completed, compressed gas is injected into the airbag 322, causing the airbag 322 to open rapidly, thereby allowing the second sealing shell 330 to float quickly on the sea surface. After floating on the sea surface, multiple second sealing shells 330 are collected together by the deployment and retrieval mechanism 350.

[0062] Specifically, the compression tank 321 is located in the middle of the cylindrical part of the second sealing housing 330, and the two take-up and take-down mechanisms 350 are located on both sides of the compression tank 321.

[0063] Please see Figure 1 , Figure 5 and Figure 9 According to some embodiments of this application, optionally, the recovery mechanism 500 includes a recovery component 510 connected to the drone body 100 and a third drive motor 520 connected to the recovery component 510. The third drive motor 520 is used to drive the recovery component 510 to rotate so as to retract the opened airbag 322. Specifically, the recovery component 510 includes a connecting part connected to the third drive motor 520 and a plurality of recovery columns connected to the connecting part.

[0064] Please see Figure 1 , Figure 9 and Figure 10 The airbag 322 has several pre-drilled holes 3221, and each pre-drilled hole 3221 contains a mesh 3222, into which the recovery component 510 can be inserted. More specifically, the recovery column can be inserted into the mesh 3222. The third drive motor 520 drives the recovery component 510 to rotate, which can retract the opened airbag 322.

[0065] The third drive motor 520 drives the recovery component 510 to rotate. Alternatively, the lowering inspection mechanism 300 can be adjusted to be below the sleeve 240. After the main body of the UAV lands on the sea surface, the lowering inspection mechanism 300 can be inserted into the sleeve 240 to achieve the recovery of the lowering inspection mechanism 300.

[0066] Please see Figure 1 , Figure 6 , Figure 7 and Figure 8 According to some embodiments of this application, optionally, a battery 360, a generator, and a rectifier and voltage regulator circuit 370 are further provided inside the second sealed housing 330. The battery 360 is electrically connected to the buoyancy component 320, the retraction and deployment mechanism 350, and the adjustment mechanism; the generator is electrically connected to the rectifier and voltage regulator circuit 370, and the rectifier and voltage regulator circuit 370 is electrically connected to the battery 360. A plug 241 electrically connected to the battery 360 is provided on the sleeve 240, and the plug 241 is electrically connected to the UAV body 100. The battery 360 provides power to the buoyancy component 320, the retraction and deployment mechanism 350, and the adjustment mechanism.

[0067] After the second sealing housing 330 is collected, the first propeller 342 stops operating. At this time, the second sealing housing 330 floats on the sea surface. The seawater impacts the first propeller 342, causing it to rotate. The mechanical energy of the rotating first propeller 342 can be transferred to the generator to generate electricity. Then, the electricity is rectified and regulated by the rectifier and voltage regulator circuit 370 before being discharged into the battery 360 for storage.

[0068] After the lowered inspection mechanism 300 is inserted into the sleeve 240, the battery 360 is connected to the plug 241. The electrical energy in the battery 360 can be discharged into the drone body 100 for use when the drone body 100 returns to base, thereby improving the endurance of the drone body 100.

[0069] Please see Figure 1 , Figure 2 and Figure 3 According to some embodiments of this application, optionally, the UAV body 100 includes a body 110, a plurality of floats 120, and a plurality of second propellers 130 connected to the body 110. The floats 120 are all connected to the body 110 via connecting rods 140, and a recovery mechanism 500 is connected to the floats 120. Specifically, the plurality of second propellers 130 and the plurality of floats 120 are all spaced apart circumferentially along the body 110. Exemplarily, there are four second propellers 130 and two floats 120.

[0070] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
