Description

Technical Field

[0001] The invention relates to the field of submersibles, in particular to an underwater robot capable of carrying a drone. Background Art

[0002] The ocean, as the largest ecosystem on earth, has complex and changing environmental conditions that provide unlimited possibilities and challenges for scientific research, resource development, and environmental protection. In order to achieve the purpose of ocean research and development, it is necessary to observe and monitor the ocean.

[0003] At present, there are many ways to monitor the ocean, such as traditional artificial diving. However, due to the complex marine environment, it is difficult and risky to carry out diving operations. That is, there are still limitations in operability, safety and economy. These limitations are more obvious in deep-sea exploration and long-term ocean monitoring missions.

[0004] With the advancement of technology, especially in the fields of materials science, robotics and artificial intelligence, in order to solve the problem of artificial submersible detection, researchers have turned their attention to the research and development of underwater robots. At present, there are many finished products of underwater robots, such as Loon Copter, Sea Scout, Flying Fish, Sea Scout, FlyingFish, etc. However, they all have some defects.

[0005] For example, Loon Copter mainly realizes the transition from the water surface to underwater, but this design is still limited to specific transition scenarios and fails to truly achieve comprehensive cross-media operations; the fixed-wing Sea Scout and Flying Fish mainly adopt the structural design of traditional aircraft, emphasizing the ability to move on the water surface, but lack adaptability in different environments; as mentioned in the previous paragraph, it can be seen that domestic and foreign research in the field of cross-media autonomous underwater vehicles (AUVs) mainly focuses on applications in specific environments, usually a single medium in the air or underwater, and cannot work well both underwater and in the air.

[0006] For example, fixed-wing amphibious drones such as Sea Scout and FlyingFish developed by the University of Michigan can achieve longer endurance and higher flight speeds. In terms of non-variable configurations, although the traditional watercraft layout performs well in surface motion, it has greater resistance underwater and is structurally vulnerable.

[0007] Most amphibious drones have a fixed design, which is not conducive to adding additional functional modules, limiting the application potential and flexibility of the equipment in different tasks. In contrast, modular design can make the equipment more adaptable and scalable in different tasks, and facilitate functional adjustment and upgrade according to mission requirements;

[0008] Some drones use a variable configuration design, such as the Switchblade drone, which uses a launcher to bring it to the water surface for dry launch. However, its requirements for sealing and pressure resistance are not high, and it focuses more on performance in a specific environment rather than the strict sealing and pressure resistance required for cross-media operation.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] In the drawings of the specific embodiments of the present invention, in order to better and more clearly describe the working principles of the various components in the system, the connection relationship of the various parts in the device is shown, which only clearly distinguishes the relative position relationship between the various components, and cannot constitute a limitation on the signal transmission direction, connection sequence and size, dimensions and shape of the components or structures.

[0039] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0040] Example 1

[0041] First, the working process of the underwater robot capable of carrying a drone of the present invention is described:

[0042] The present embodiment provides an underwater robot that can carry a drone, so that the underwater robot has a drone cabin for accommodating the drone. When the underwater robot moves to a specified position underwater, the robot releases the drone after surfacing according to the received release signal, and completes some monitoring projects on the surface of the water through the drone. At the same time, the underwater robot dives underwater to complete some monitoring projects underwater. When the drone completes the monitoring projects on the water surface, the underwater robot recovers the drone after surfacing according to the received recovery signal. The drone is accommodated in the drone cabin of the underwater robot and completes the monitoring of other projects as the underwater robot dives.

[0043] like Figure 1-5 As shown, the structure of the underwater robot capable of carrying a drone of the present invention is described:

[0044] The underwater robot includes a main body 1, two propeller groups 2 and two unmanned cabins 3. The main body 1 includes a cabin 11, which is set as a cylindrical structure, one end is set as an opening, and the other end is sealed. The cabin 11 is made of materials with excellent pressure resistance and corrosion resistance so that it can be used for a long time in a salt water environment. In addition, the cylindrical shape helps to reduce the resistance caused by water flow and improve navigation efficiency. The length and diameter of the cabin 11 are determined according to the hydrodynamic principles and the space requirements of the internal equipment. A hemispherical shell 12 is set at the opening of the cabin 11, so the hemispherical shell 12 is made of a transparent material. At the same time, a camera 14 and a controller 15 are set inside the space formed by the hemispherical shell 12 and the cabin 11. The camera 14 can not only be used for underwater photography, but also for environmental monitoring and data collection. The controller 15 can be set as a programmable controller (PLC) and adopts an advanced PID control algorithm to ensure the stability and controllability of the robot underwater. A mounting frame 16 is provided on the inner side of the cabin 11, and a battery pack 17 is provided on the mounting frame 16. The battery pack 17, the propeller, the camera 14, etc. are all connected to the controller 15. Fig.14 As shown, the controller 15 can be used to control the operation of the propeller, camera 14, etc., to achieve the movement of the underwater robot and the monitoring of the environment in which it is located, and the battery pack 17 provides power for the operation of the underwater robot. Two propeller groups 2 are respectively arranged at the front and rear ends of the main body 1, and each propeller group 2 includes two first propellers 21. The two first propellers 21 have different directions. Therefore, the movement of the underwater robot can be controlled by the operation of the first propeller 21, which provides convenience for completing environmental monitoring in different areas. Two sets of unmanned aircraft cabins 3 are symmetrically arranged on both sides of the main body 1, and are both arranged between the two propeller groups 2. The unmanned aircraft cabin 3 can be opened and closed according to needs, which provides convenience for storing the drone in the unmanned aircraft cabin 3 and moving it to the corresponding place with the underwater robot. When the drone moves to the place to be monitored, the unmanned aircraft cabin 3 floats to the surface and opens, and the drone flies out of the unmanned aircraft cabin 3 to monitor the area.

[0045] It should be noted that the lithium battery used in the battery pack preferably has the following specifications: 3300mAh-30C-11.1V-3S1P-XT60; size (H*W*L) is 21*44*141mm. Fig.14 shown.

[0046] like Figure 4 , Figure 6As shown, in order to stably install the propeller group 2 on the side of the main body 1, two groups of fixing frames 13 are fixedly arranged on the side wall of the cabin 11, and the two groups of fixing frames 13 are arranged on the upper and lower sides of the cabin 11. The sides of the two first propellers 21 of the same propeller group 2 adjacent to each other are both provided with first connecting plates 22, and the ends of the two first connecting plates 22 adjacent to each other are both arranged in an arc structure. At the same time, the annular sleeve composed of the two first connecting plates 22 is arranged on the cabin 11, and is connected to the ends of the fixing frames 13 by bolts, that is, the two groups of propeller groups 2 are arranged at both ends of the fixing frames 13. This arrangement realizes the stable installation of the first propeller 21, and at the same time provides convenience for disassembly, maintenance and replacement according to needs.

[0047] like Figure 8 , Fig. 9 , Fig.12 , Fig.13 As shown, in order to realize the storage of the drone, the drone cabin 3 includes a first connecting plate group 34, a storage cabin 33, a pressing mechanism 31 and a reinforcing mechanism 35. The top of the storage cabin 33 is set to be open, and annular convex plates 331 are fixedly provided at the upper and lower ends of the outer side. A sealing ring groove 332 is provided at the opening of the storage cabin 33. The number of the sealing ring grooves 332 is determined according to demand. A sealing ring is provided in each sealing ring groove 332, and the top of the sealing ring protrudes from the sealing ring groove 332. In order to achieve sealing of the top of the receiving chamber 33 through the pressing mechanism 31, the pressing mechanism 31 includes a first servo 311 and a pressure plate 312. The first servo 311 is arranged on the side of the receiving chamber 33, and the pressure plate 312 is installed on the output shaft of the first servo 311. The pressure plate 312 can be controlled to rotate under the action of the first servo 311, thereby providing convenience for the pressure plate 312 to fit the receiving chamber 33. When the pressure plate 312 fits the receiving chamber 33, it squeezes the sealing ring to achieve a sealed connection between the pressure plate 312 and the receiving chamber 33, thereby preventing water seepage when the device dives. In order to make the pressure plate 312 fit more stably on the storage chamber 33, the reinforcement mechanism 35 includes a second servo 351 and a support plate 352. The second servo 351 is also installed on the side of the storage chamber 33. At the same time, the support plate 352 is installed on the output shaft of the second servo 351. Under the action of the second servo 351, the support plate 352 is controlled to rotate, thereby pressing the edge of the pressure plate 312, so that the pressure plate 312 is stably fitted to the storage chamber 33.

[0048] like Fig. 9 , Fig.10As shown, in order to achieve stable connection of the accommodation chamber 33, the pressing mechanism 31 and the reinforcing mechanism 35, the first connecting plate group 34 includes an upper connecting plate 341, a lower connecting plate 342, a mounting frame 343 and a fixing plate 344. The mounting frame 343 and the fixing plate 344 are both arranged between the upper connecting plate 341 and the lower connecting plate 342, and are connected to both ends of the connecting plates by bolts. A third arc surface and a second arc surface 346 are respectively arranged at one end of the mounting frame 343 and the fixing plate 344 close to each other. The accommodation chamber 33 is arranged through the upper connecting plate 341 and the lower connecting plate 342, and the second arc surface 346 and the third arc surface are both installed in contact with the outer side of the accommodation chamber 33. Therefore, the accommodation chamber 33 can be relatively stably installed relative to the mounting frame 343 and the fixing plate 344. At the same time, the upper connecting plate 341 and the lower connecting plate 342 are respectively connected to the adjacent sides of the two annular convex plates 331, thereby controlling the accommodation chamber 33 to be stably installed relative to the first connecting plate group 34. The top of the fixing plate 344 is provided with a mounting groove 347, the second steering gear 351 is mounted at the mounting groove 347, and the first steering gear 311 is mounted at the mounting frame 343, thereby achieving stable installation of the first steering gear 311 and the second steering gear 351, and providing convenience for controlling the opening and closing of the storage compartment 33 through the pressing mechanism 31 and the reinforcement mechanism 35 to achieve storage or operation of the drone. The first steering gear 311 and the second steering gear 351 are both connected to the controller 15, and the first steering gear 311 and the second steering gear 351 can be notified to work through the controller 15.

[0049] like Figure 8 , Fig.11 As shown, the unmanned aircraft cabin 3 also includes a second propeller 32, and a second connecting plate 321 is provided on the side of the second propeller 32. The top of the second connecting plate 321 is connected to the first connecting plate group 34 by bolts to achieve stable installation of the second propeller 32. The second propeller 32 is located outside the two accommodating cabins 33, and its orientation is different from that of the first propeller 21. The first propeller 21 and the second propeller 32 use vector propulsion and are respectively installed at six positions of the cabin 11 to achieve various underwater actions of the robot, such as moving forward, backward, turning, floating and diving. The first propeller 21 and the second propeller 32 can be controlled separately or used in combination.

[0050] It should be noted that the propeller preferably adopts an underwater propeller commonly used in the field of ocean exploration. The underwater propeller is often used in ocean exploration and is easy to install in an underwater platform system.

[0051] Example 2

[0052] like Figure 7As shown, on the basis of Example 1, in order to control the two groups of unmanned cabins 3 to be stably installed relative to the cabin body 11 and to be quickly disassembled and assembled according to needs, the ends of the two fixing plates 344 adjacent to each other are provided with a first arc surface 345, and the two fixing plates 344 are connected by bolts to form a second connecting plate group 4, the second connecting plate group 4 includes two groups of third connecting plates 41 distributed front and back, the front and back distribution is based on the length direction of the cabin body 11, each group includes two third connecting plates 41 symmetrical up and down, the third connecting plate 41 is detachably connected to the fixing frame 13 by bolts, the first arc surface 345 is in close contact with the cabin body 11, and under the cooperation of the third connecting plate 41 and the first arc surface 345, the first connecting plate group 34 is stably installed on the side of the cabin body 11, so as to realize the stable installation of the unmanned cabin 3. In addition, the third connecting plate 41 is detachably connected to the fixing frame 13, which provides convenience for disassembly according to needs.
