DETAILED DESCRIPTION

[0022] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1-Figure 7As shown, an underwater unmanned vehicle includes a body 1, a water storage chamber 2, and a water control mechanism. The body 1 is provided with a water storage chamber 2 and a water control mechanism, and the water control mechanism is used to control the water in and out of the water storage chamber 2. The body 1 is also equipped with a controller 4, a main battery 5, a radio transmission module and a camera, and is fixed with four horizontal servo motors 6, and the rotating shafts of each of the servo motors 6 are coaxially fixed with propellers 7. The bottom of the body 1 is provided with a receiving groove 8 penetrating downward, and a sampling groove 9 is provided at the bottom. The upper part of the sampling groove 9 is provided with an on-off mechanism for controlling whether the sampling groove 9 is connected to the outside world. The bottom of the sampling groove 9 is connected with the receiving groove 8 and forms an upper opening 11. A vertical lower support tube 12 is installed at the bottom of the body 1, and a lower opening 13 is radially penetrated on the upper part of the lower support tube 12. The receiving groove 8 is sealed and slidably connected with an upper support tube 14, and a No. 2 electric push rod 15 is fixed on the upper part. The push rod of the No. 2 electric push rod 15 is fixed to the upper support tube 14, and the upper support tube 14 is radially penetrated with an entrance and exit 16, and can be sealed and slidably connected with the lower support tube 12 in an up and down manner, and the entrance and exit 16 can be aligned and communicated with the upper through port 11, and when aligned and communicated with the upper through port 11, the lower through port 13 is sealed and blocked by the upper support tube 14, the upper through port 11 can be blocked and blocked by the upper support tube 14, and when blocked and blocked by the upper support tube 14, the lower through port 13 can not be blocked and blocked by the upper support tube 14, and a speed regulating motor 17 is installed on the upper part of the accommodating groove 8, and the output shaft of the speed regulating motor 17 is connected to a vertical auger 19 through a coupling mechanism, and the auger 19 is gap-inserted with the upper support tube 14 and the lower support tube 12, and the bottom protrudes from the bottom end of the lower support tube 12, and the controller 4, the main battery 5, the radio transmission module, the camera, the servo motor 6 and the speed regulating motor 17 are electrically connected.

[0024] When in use, the controller 4 is controlled by radio signals and a radio transmission module. The controller 4 controls the forward and reverse rotation of each servo motor 6 to adjust the horizontal position of the body 1. The water inlet and outlet of the water storage chamber 2 are controlled by controlling the water control mechanism. When the volume of water in the water storage chamber 2 is large, the buoyancy of the unmanned aerial vehicle is reduced, and the unmanned aerial vehicle sinks. When the volume of water in the water storage chamber 2 is small, the buoyancy of the unmanned aerial vehicle is increased, and the unmanned aerial vehicle floats, thereby controlling the buoyancy and sinking of the aircraft. When sampling is not needed, the No. 2 electric push rod 15 is controlled to retract the push rod, so that the upper opening 11 can be sealed and blocked by the upper support tube 14, so that water cannot be poured into the sampling slot 9; and when it is necessary to collect water samples at a certain height, the No. 2 electric push rod 15 is controlled to extend the push rod, so that the inlet and outlet 16 can be connected with the upper opening 11, so that water can be poured into the sampling slot 9; when it is necessary to sample the flowing solid materials such as mud and sand on the bottom of the water, the unmanned aerial vehicle is controlled to sink to the bottom of the water, and then the speed regulating motor 17 is controlled to rotate forward at a slow speed, so that the auger 19 can gradually rotate into the mud and sand, and then the mud and sand are transported upward under the obstruction of the lower support tube 12, and at the same time, the No. 2 electric push rod 15 is controlled to extend the push rod, so that the inlet and outlet 16 is connected with the upper opening 11, so that the mud and sand can pass through the outlet The inlet 16 and the upper passage 11 enter the sampling trough 9, and at the same time, the on-off mechanism is controlled to open, so that the mud and water in the sampling trough 9 are discharged first. After the mud is continuously replenished into the sampling trough 9 for a period of time, the on-off mechanism is controlled to close, and then the speed regulating motor 17 is controlled to stop, and the No. 2 electric push rod 15 is controlled to retract, so that the upper support tube 14 blocks the upper passage 11, and then the sample in the sampling trough 9 is stabilized; when the lower passage 13 is not blocked by the upper support tube 14, by controlling the forward and reverse rotation of the speed regulating motor 17, upward and downward water flows can be generated, and the upward water flow is discharged outward through the lower passage 13, and the downward water flow flows into the lower support tube 12 through the lower passage 13, and is discharged from the bottom of the lower support tube 12, thereby pushing the body 1, thereby accelerating the sinking and floating of the underwater unmanned vehicle.

[0025] The coupling mechanism includes a hollow shaft 20, a guide block 21, a sliding frame 22, a compression spring 23, a roller 24, a plug rod 25, a No. 1 electric push rod 26, a push plate 27, a limit plate 28, a limit ring 29, and a guide rod 30. The rotating shaft of the speed regulating motor 17 is coaxially fixed with the hollow shaft 20. The hollow shaft 20 is fixed with a radially fixed guide block 21 and is sealed and plugged with the upper support cylinder 14. The hollow shaft 20 can be sealed and slid up and down and sealed and rotated compared with the upper support cylinder 14. The guide block 21 is horizontally slidably connected to the sliding frame 22. A compression spring 23 is fixed between the sliding frame 22 and the guide block 21, and a vertical roller 24 is rotatably connected. The sliding frame 22 is fixed with a horizontal plug rod 25. The plug rod 25 is horizontally gap-plugged with the hollow shaft 20. The hollow shaft 20 is axially plugged with the shaft of the auger 19. The plug rod 25 is axially plugged with the shaft of the auger 19. Radially plug-in, a horizontal No. 1 electric push rod 26 is fixed in the accommodating groove 8, and a vertical push plate 27 is fixed to the push rod end of the No. 1 electric push rod 26. When the No. 1 electric push rod 26 extends out of the push plate 27 and the speed regulating motor 17 rotates, the push plate 27 can contact the roller 24 and push the roller 24 and the sliding frame 22 so that the insertion rod 25 is disengaged from the shaft of the auger 19. A horizontal limit plate 28 is fixed on the outer edge of the upper part of the lower support cylinder 12, and the limit plate 28 is plugged up and down with the body 1. The limit plate 28 has a built-in auxiliary battery or dry battery, and also has a built-in radio transmission module. The auxiliary battery or dry battery is electrically connected to the radio transmission module. A limit ring 29 is coaxially fixed to the inner wall of the bottom of the lower support cylinder 12, and a guide rod 30 is radially fixed to the auger 19. The guide rod 30 is horizontally slidably connected to the limit ring 29, and the body 1 is also equipped with a salvage mechanism.

[0026] Furthermore, when taking samples of mud and sand, if it is found that the sampling point is special and needs to be marked, when the auger 19 has been screwed into the mud and sand, by controlling the No. 1 electric push rod 26 to extend the push rod, the speed regulating motor 17 can make the roller 24 contact with the push plate 27 when rotating, so that it is squeezed and pushed by the push plate 27, and then the sliding frame 22 overcomes the elastic repulsion of the compression spring 23 and moves, so that the insertion rod 25 is disengaged from the shaft of the auger 19. As the body 1 floats up, the auger 19 is retained in the mud and sand, and driven by the guide rod 30, the lower support tube 12 is also retained in the mud and sand. At this time, the radio transmission module is used to mark the point, and the retained auger 19, the lower support tube 12 and the limit plate 28 can be salvaged later by a salvage mechanism or an external salvage device, and the position of the sampling point can be known by the radio transmission module, which is convenient for salvage and further processing of the sampling point.

[0027] The on-off mechanism includes a piston groove 31, a piston 32, a water delivery hole 33, a water through hole 34, an inner tension spring 35, a wedge rod 36, a lower support frame 37, and a wedge block 38. The outer wall of the body 1 is provided with a plurality of horizontal piston grooves 31, the piston groove 31 is connected to the receiving groove 8, and a piston 32 is sealed and horizontally slidably connected in each of the piston grooves 31. The piston 32 is penetrated by a water delivery hole 33. The upper part of the water delivery hole 33 radially penetrates the end of the piston 32 close to the outer wall of the body 1, and the bottom of the water delivery hole 33 radially penetrates the end of the piston 32 close to the receiving groove 8. The upper part of the sampling groove 9 is provided with a water through hole 34, the water through hole 34 is connected to the piston groove 31, and can be connected to the bottom of the water delivery hole 33 of the piston 32, and the water through hole 34 is connected to the delivery hole 33 of the piston 32. When the bottoms of the water holes 33 are connected, the upper part of the water holes 33 is connected to the outside world, and the piston groove 31 can completely seal the water holes 33. The piston 32 and the piston groove 31 are jointly fixed with an inner tension spring 35. The piston 32 has a tendency to approach the receiving groove 8 under the elastic tension of the inner tension spring 35. Each piston 32 is respectively fixed with a horizontal wedge rod 36. A plurality of vertical lower support frames 37 are fixed to the top of the upper support cylinder 14. A wedge block 38 is fixed to the upper part of the lower support frame 37. The wedge surface of the wedge block 38 can contact the wedge surface of the wedge rod 36. When the upper support cylinder 14 moves downward, the wedge block 38 can squeeze the wedge rod 36 so that the piston 32 overcomes the elastic tension of the inner tension spring 35 and moves away from the receiving groove 8.

[0028] Furthermore, when the No. 2 electric push rod 15 retracts the push rod, the wedge block 38 moves away from the wedge rod 36. At this time, the piston 32 retracts into the piston groove 31 under the elastic tension of the internal tension spring 35, thereby preventing the sample in the sampling groove 9 from flowing out. When the No. 2 electric push rod 15 extends the push rod, that is, the upper opening 11 is aligned and connected with the entrance and exit 16, under the squeezing of the wedge block 38, the pistons 32 move away from each other. At this time, the water hole 34 is connected with the water delivery hole 33, so that the sampling groove 9 can be connected with the outside through the water hole 34 and the water delivery hole 33, and then the sample is discharged from here.

[0029] The salvage mechanism includes a clamp 39, an electromagnet 40, and a permanent magnet 41. The bottom of the body 1 is hinged with a clamp 39, and the clamp 39 is in an "L"-shaped structure. A plurality of vertical electromagnets 40 are fixed at equal angles on the circumference of the bottom of the body 1. A permanent magnet 41 is fixed to each of the clamps 39, and the electromagnets 40 correspond to the permanent magnets 41 up and down. The electromagnets 40 are electrically connected to the controller 4. The bottom of the body 1 is made of a material that can be magnetically attracted. When the clamp 39 is swung downward to a certain angle, the permanent magnet 41 can be magnetically attracted to the bottom of the body 1.

[0030] Furthermore, when not in the salvage state, the electromagnet 40 magnetically attracts the permanent magnet 41, and the jaws 39 are open to each other. When salvage is required, the electromagnet 40 is passed with a reverse current, so that the jaws 39 are extended downward, and finally the permanent magnet 41 is magnetically attracted to the bottom of the body 1. At this time, the jaws 39 are close to each other, so as to grab and salvage the limit plate 28.

[0031] The bent parts of each of the clamping jaws 39 are respectively connected to a vertical light rod 42 for sliding up and down. The light rod 42 and the clamping jaws 39 are fixed with an external tension spring 43. The light rod 42 has a tendency to move downward under the elastic tension of the external tension spring 43. When each of the clamping jaws 39 swings downward to a certain extent, the light rods 42 can gather and touch each other.

[0032] Furthermore, when salvage is required, a reverse current is passed through the electromagnet 40, so that each clamping claw 39 pops up downward, and finally causes the permanent magnet 41 to be magnetically attracted to the bottom of the body 1. At this time, the clamping claws 39 are close to each other, and when the light rod 42 is blocked by the lower support tube 12, it can overcome the elastic tension of the external tension spring 43 and shrink compared to the clamping claw 39, thereby grabbing and salvaging the limit plate 28. If there is no obstruction from the lower support tube 12, the light rods 42 that touch each other can also salvage underwater objects (such as stones, sea cucumbers, starfish, etc.), thereby increasing the scope of application of salvage.

[0033] The water control mechanism includes a No. 3 electric push rod 44 and a piston plate 45. The water storage chamber 2 runs through the top of the body 1. The piston plate 45 is sealed and slidably connected up and down in the water storage chamber 2. A vertical No. 3 electric push rod 44 is fixed to the upper part of the body 1. The push rod of the No. 3 electric push rod 44 is fixed to the piston plate 45 and is electrically connected to the controller 4.

[0034] Furthermore, by controlling the extension and retraction of the No. 3 electric push rod 44, the piston plate 45 can be moved up and down along the water storage chamber 2, thereby controlling the volume of water entering the upper part of the water storage chamber 2, thereby controlling the displacement, adjusting the size of the buoyancy, and achieving floating and sinking.

[0035] A concave water storage tank 46 is formed at the top of the piston plate 45 . An atomizer 47 is fixed in the water storage tank 46 . The atomizer 47 is electrically connected to the controller 4 .

[0036] Furthermore, when the unmanned aerial vehicle sinks and finally floats to the surface, a certain volume of water will be stored in the water tank 46. The atomizer 47 is then controlled to work, so that the water in the water tank 46 can be atomized, thereby improving the recognizability and facilitating observation and operation by the user.

[0037] A horizontal upper support frame 48 is fixed to the top of the body 1, a vertical piercing needle 49 is fixed to the bottom of the middle of the upper support frame 48, a paint bag 50 is pasted in the water storage tank 46, and the paint bag 50 stores water-soluble liquid paint that is obviously different from the use environment. The piercing needle 49 can pierce the paint bag 50 to allow the paint to flow into the water storage tank 46.

[0038] Furthermore, as the No. 3 electric push rod 44 is fully extended, the piston plate 45 rises to the highest point, so that the paint bag 50 is punctured by the needle 49. At this time, the paint is mixed with the water in the water tank 46 and then atomized, which can improve the recognition, making it easier for users to observe and operate.

[0039] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
