[0019] The present invention will be further described below with reference to the accompanying drawings and examples, but they are not intended to limit the present invention.

[0020] Embodiment: An underwater detection device, such as Figure 1 and Figure 2 As shown, the device comprises a housing 1 with propellers 2 disposed on either side and six bionic fish bladders 3 disposed on its top surface. The housing 1 has an internal storage chamber, which can house electronic components such as a control circuit board for electronic control. A fish bladder control device 4 is located in the center of the chamber, connected to the bionic fish bladders 3 and used to control their size. Drive control devices 5 are located on either side of the chamber, connected to the propellers. Three anchor motors 6 are also located within the chamber, with their outputs connected to an anchor hook 7 via cables. The present invention distributes multiple bionic fish bladders 3 on the top surface of the shell 1. The bionic fish bladders 3 are connected to the fish bladder control device 4 through a pipe. The fish bladder control device 4 controls the size of each bionic fish bladder 3, thereby controlling the suspension position and suspension posture of the entire detection device. At the same time, the propeller is operated by the driving control device 5 to realize the movement of the detection device, and the positioning limit is realized by the anchor hook 7.

[0021] Preferably, Figure 3As shown, the swim bladder control device 4 includes a sleeve 8, which is filled with a low-density liquid (such as pentane), and a piston 9 is provided in the sleeve 8; a swim bladder motor 10 is provided in the accommodating chamber, and the output end of the swim bladder motor 10 is connected to a rotating sleeve 11; the rod of the piston 9 passes through the rotating sleeve 11 and is threaded; a plurality of channel switches 12 are provided at the end of the sleeve 8, and each channel switch 12 is connected to the corresponding bionic swim bladder 3 through a pipeline. The swim bladder motor 10 controls the operation of the piston 9, and then controls the volume of the low-density liquid (such as pentane) contained in the sleeve 8 to achieve control of the swim bladder installed on the outside of the detector, thereby achieving control of the hovering of the detection device in the water and the hovering angle. The control method is as follows:

[0022] 1. When controlling the volume of each bionic fish maw 3, close the other channel switches 12 and only open the channel switch 12 corresponding to the fish maw to be controlled to control the internal liquid volume.

[0023] 2. Control of the hovering position: The control circuit board calculates the gravity of the detection device itself and the required buoyancy, evenly distributes the required increase or decrease in volume, and injects or extracts liquid from each bionic fish bladder 3 in turn, so that the detection device as a whole is suspended in a fixed position.

[0024] 3. When adjusting the suspension state of the detector, the position that needs to be raised or lowered is judged, the volume that needs to be increased or decreased is evenly distributed, the liquid in other bionic fish bladders 3 is extracted or injected, and the total volume of the extracted or injected liquid is injected or extracted into the bionic fish bladder 3 at the corresponding position.

[0025] Preferably, if Figure 4 and Figure 5As shown, the drive control device 5 includes a drive motor 13, the output end of the drive motor 13 is connected to the first rotating shaft 15 via the first sliding sleeve 14, and the output end of the first rotating shaft 15 is connected to the first gear 16; the drive control device 5 also includes an adjusting gear sleeve 17, and the inner circumference of the adjusting gear sleeve 17 is distributed with a first internal circular tooth 18, a toothless portion 19 and a second internal circular tooth 20; the first internal circular tooth 18 of the adjusting gear sleeve 17 is used to engage with the first gear 16, and the second internal circular tooth 20 of the adjusting gear sleeve 17 is engaged with a second gear 21, and the second gear 21 is connected to a transmission rod 22, and a first bevel gear 23 is provided at the end of the transmission rod 22; the propeller is connected to a propeller rod 24, the propeller rod 24 is perpendicular to the transmission rod 22, and a second bevel gear 25 is provided at the end of the propeller rod 24, and the second bevel gear 25 is engaged with the first bevel gear 23. The drive control device 5 also includes an angle motor 26. The output end of the angle motor 26 is connected to a worm 27, which is engaged with a turbine 28. A positioning rod 29 is connected to the middle of the turbine 28. The end of the positioning rod 29 is provided with a rod sleeve 30. The paddle shaft 24 is inserted into the rod sleeve 30. A sealing disk 31 is rotatably mounted on the housing 1. The sealing disk 31 is provided with a protective sleeve 32. The positioning rod 29 passes through the middle of the sealing disk 31. The transmission rod 22 passes through the side of the sealing disk 31. The positioning rod 29 and the transmission rod 22 are both located in the protective sleeve 32. The first rotating shaft 15 is also provided with an electromagnetic disk 33; the internal chamber is also provided with an electromagnet, which is connected to a control circuit board and is used to open and close the circuit, causing the electromagnet to generate an attractive or repulsive force on the electromagnetic disk 33. A second rotating shaft 34 is passed through the electromagnetic disk 33. One end of the second rotating shaft 34 is connected to a generator motor 36 via a second sliding sleeve 35, and the other end of the second rotating shaft 34 is connected to a generator gear 37, which is used to mesh with the first internal circular gear 18. The second rotating shaft 34 is shorter than the first rotating shaft 15, which allows for misalignment between the first gear 16 and the second gear 21 when they engage with the adjustment gear sleeve 17.

[0026] The drive control device 5 in this embodiment has two states: a power generation state and a travel state.

[0027] When the detection device is about to enter the self-generating state, the detector enters the moving state, with its speed being the same as the water flow speed but in the opposite direction. The three anchor devices are lowered, the drive motor 13 and the propeller 2 are stopped, and the anchor devices are anchored to the bottom of the water flow under the action of the water flow for fixation. The first sliding sleeve 14 and the second sliding sleeve 35 are moved by the electromagnet attracting and repelling the electromagnetic disk 33, so that the first gear 16 moves forward to the toothless portion 19 and does not mesh with the adjusting gear sleeve 17, while the second gear 21 moves forward to mesh with the first internal circular tooth 18 in the adjusting gear sleeve 17. At this time, the water flow acts on the propeller 2, driving the propeller 2 to rotate, and the kinetic energy is transferred to the generator through the propeller rod 24, the second bevel gear 25, the first bevel gear 23, the transmission rod 22, the second gear 21, the adjusting gear sleeve 17, the power generation gear 37 and the second rotating shaft 34, thereby driving the generator to generate electricity.

[0028] When the detection device is converted to the moving state, the electromagnet attracts and repels the electromagnetic disk 33 to realize one end of the first sliding sleeve 14 and the second sliding sleeve 35, so that the first gear 16 retreats to the first internal circular tooth 18 in the adjusting gear sleeve 17, and the second gear 21 retreats to separate from the first internal circular tooth 18 in the adjusting gear sleeve 17, and then the angle motor 26 runs, and the turbine 28, worm 27, positioning rod 29, rod sleeve 30 and paddle rod 24 are used to make the impeller of the propeller 2 rotate as a whole to be perpendicular to the bottom of the water flow, and then the drive motor 13 is started, and the propeller 2 is driven to rotate through the first rotating shaft 15, the first gear 16, the adjusting gear sleeve 17, the second gear 21, the transmission rod 22, the first bevel gear 23, the second bevel gear 25 and the paddle rod 24 to generate thrust, pulling the anchor hook 7 out from the bottom, and the anchor motor 6 is started to retract the anchor hook 7.

[0029] After being folded, the angle motor 26 is still used to operate, and the turbine 28, worm 27, positioning rod 29, rod sleeve 30 and propeller rod 24 are used to rotate the impeller of the propeller 2 to a suitable angle. Then the drive motor 13 is started, and the propeller 2 is driven to rotate and generate thrust through the first rotating shaft 15, first gear 16, adjustment gear sleeve 17, second gear 21, transmission rod 22, first bevel gear 23, second bevel gear 25 and propeller rod 24, thereby achieving travel. Of course, during the travel process, the angle motor 26 can also be operated to adjust the angle during travel.

[0030] In summary, the present invention distributes a plurality of bionic fish bladders 3 on the top surface of the housing 1, and the bionic fish bladders 3 are connected to the fish bladder control device 4 through a pipe. The fish bladder control device 4 controls the size of each bionic fish bladder 3, thereby controlling the suspension position and suspension posture of the entire detection device. At the same time, the propeller is driven by the control device 5 to realize the movement of the detection device, and the positioning limit is realized by the anchor hook 7. Furthermore, the present invention can realize the movement and angle adjustment of the propeller 2 through the drive control device 5, which facilitates the operation of the detection device in the water. In addition, the present invention is also provided with a generator, and can also use the propeller 2 to generate electricity, which is convenient for endurance.
