Description

Technical Field

[0001] This invention relates to the field of surveying vessels, specifically an automatic surveying device for an unmanned vessel. Background Technology

[0002] Underwater topographic surveying is an important method for acquiring underwater geographic information, but it is much more difficult than land-based surveying. Traditional deep-sea surveying methods rely on underwater detectors and RTK (Real-Time Kinematics) carried out by personnel on board vessels, while observations of tidal flats and wet shallows require handheld measuring instruments. Traditional surveying methods suffer from numerous safety hazards and issues such as omissions and inaccuracies in the data. Unmanned underwater vehicles (UAVs) can effectively solve these problems. To cope with complex underwater terrain and areas inaccessible to personnel, the advantages of UAVs become apparent. UAVs are lightweight, small in size, and have a shallow draft, enabling them to transport goods on water and operate in both deep and shallow waters, saving significant labor costs. In complex water environments, the use of UAVs can improve the safety and reliability of personnel.

[0003] However, due to the low weight of the unmanned survey vessel, it is prone to capsizing and damage in rough seas. Summary of the Invention

[0004] To address the existing problems, this invention provides an automatic measurement device for unmanned vessels, which, when used in conjunction with other technologies, can effectively solve the problems mentioned in the background art.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] An automatic measurement device for an unmanned surface vessel (USV) includes a hull. A lateral buoyancy mechanism is disposed on the outer side of the hull. The lateral buoyancy mechanism includes a buoyancy cylinder, a support frame, and an inner airbag. Corrugated floats are arrayed on the outer side of the inner airbag. A one-way valve is installed between the corrugated floats and the inner airbag. A sealing cover is installed on the outer end of the corrugated floats. A limit groove is formed on the outer side of the corrugated floats on the side surface of the buoyancy cylinder. A limit block is disposed on one side of the sealing cover inside the limit groove. A tap is installed on one side of the inner airbag. The lower surface of the support connecting frame is equipped with an air-blowing mechanism, and an air-inflating pipe is connected between the air-blowing mechanism and the branch pipe. A bulbous bow is installed on the lower surface of the hull. A measuring mechanism is installed in front of the bulbous bow on the lower surface of the hull. A protective baffle is installed in front of the measuring mechanism on the lower surface of the hull. A movable lug is installed on the inner side of the protective baffle. A rotating tooth is installed on the outer side of the movable lug. A drive tooth assembly is provided on one side of the rotating tooth. A drive motor is installed above the protective baffle inside the hull.

[0007] As a further embodiment of the present invention: an integrated compartment is installed on the upper surface of the hull, an upper cover plate is provided above the integrated compartment, a remote control antenna is installed on the outer side of the integrated compartment, and a photovoltaic power generation panel is provided on the rear surface of the integrated compartment.

[0008] As a further embodiment of the present invention: a propeller is installed on the lower surface of the hull behind the bulbous bow, and a guide vane is installed on one side of the propeller on the lower surface of the hull.

[0009] As a further embodiment of the present invention: a wireless network antenna is installed in front of the integrated compartment on the upper surface of the hull, a receiving mechanism is provided in front of the wireless network antenna, and a guardrail is installed on the upper surface of the hull.

[0010] As a further embodiment of the present invention: the closed cover plate is engaged with the limiting slot by the limiting block, and the corrugated float tube is interconnected with the inner airbag by the one-way valve.

[0011] As a further embodiment of the present invention: the branch pipe is in communication with the inner airbag, the inflation mechanism is fixedly connected to the support connecting frame, and the support connecting frame is fixedly connected to the hull by bolts.

[0012] As a further embodiment of the present invention: a control device is integrated inside the integrated compartment below the upper cover plate, and the photovoltaic power generation panel is electrically connected to the hull.

[0013] As a further embodiment of the present invention: the guide propeller is movably connected to the hull, and one end of the propeller is located inside the hull and a drive motor is installed thereon.

[0014] As a further embodiment of the present invention: the receiving mechanism is electrically connected to the wireless network antenna, and the receiving mechanism is movably connected to the hull.

[0015] As a further embodiment of the present invention: the rotating teeth mesh and rotate with the drive gear set, the shaft end of the drive motor is movably connected to the drive gear set through a gear, and the protective baffle is an L-shaped structural component.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The inflation mechanism inflates the inner airbag through the air inflator pipe and the branch pipe. After the entire inner airbag is inflated, the limiting block on the outside of the closed cover is engaged with the inside of the limiting slot, so that the side buoyancy mechanism has a large buoyancy value.

[0018] 2. The air-blowing mechanism blows air to inflate the multiple corrugated floats in an array using a one-way valve connected to the inner airbag and the corrugated floats. This causes the closed cover plate, which is locked inside the limiting slot, to pop out, thus further increasing the lateral length of the entire lateral buoyancy mechanism. At the same time, the buoyancy of the entire hull is also increased, which can prevent the hull from capsizing in large waves.

[0019] 3. The L-shaped protective baffle protects the measuring mechanism. When shooting is required, the drive motor drives the gears to mesh with multiple drive gear groups. The meshing and rotation of the drive gear groups and the rotating gears control the movable ear plate to drive the protective baffle to rotate, thereby breaking the protective baffle's obstruction of the measuring mechanism and enabling the measuring mechanism to perform normal shooting.

[0029] like Figure 1-6As shown, this embodiment provides an automatic measurement device for an unmanned surface vessel (USV), including a hull 1. A bottom keel 10 is installed on the lower surface of the hull 1. A lateral buoyancy mechanism 8 is provided on the outer side of the hull 1. The lateral buoyancy mechanism 8 includes: a buoyancy cylinder 801, a support connecting frame 803, and an inner airbag 808. Corrugated floats 802 are arrayed on the outer side of the inner airbag 808. A one-way valve 809 is installed between the corrugated floats 802 and the inner airbag 808. The corrugated floats 802 are interconnected with the inner airbag 808 through the one-way valve 809. A sealing cover plate 804 is installed on the side end. A limiting groove 810 is formed on the outer side of the corrugated float tube 802 on the side surface of the buoyancy cylinder 801. A limiting block 811 is provided on one side of the sealing cover plate 804 inside the limiting groove 810. The sealing cover plate 804 is engaged with the limiting groove 810 via the limiting block 811. A branch pipe 805 is installed on one side end of the inner airbag 808. The branch pipe 805 communicates with the inner airbag 808. The lower part of the support connecting frame 803... An air-blowing mechanism 806 is mounted on the surface of the hull. The air-blowing mechanism 806 is fixedly connected to a support connecting frame 803, which is bolted to the hull 1. An air-inflating pipe 807 connects the air-blowing mechanism 806 to a branch pipe 805. A bulbous bow 9 is mounted on the lower surface of the hull 1. A measuring mechanism 15 is mounted in front of the bulbous bow 9 on the lower surface of the hull 1. The measuring mechanism 15 can rotate at multiple angles. A protective baffle 14 is mounted in front of the measuring mechanism 15 on the lower surface of the hull 1. A protective baffle 14 is installed on the inner side of the protective baffle 14. There is a movable lug 1401, and a rotating tooth 1402 is installed on the outer side of the movable lug 1401. A drive gear assembly 1403 is provided on one side of the rotating tooth 1402. A drive motor 1404 is installed above the protective baffle 14 inside the hull 1. The rotating tooth 1402 meshes with the drive gear assembly 1403 and rotates. The shaft end of the drive motor 1404 is movably connected to the drive gear assembly 1403 through a gear. The protective baffle 14 is an L-shaped structural component. When the protective baffle 14 is installed as a whole, it can provide protection and avoid large resistance when moving.

[0030] like Figure 2-6As shown, in this embodiment, an integrated compartment 5 is installed on the upper surface of the hull 1. A top cover plate 6 is provided above the integrated compartment 5. A control device is integrated inside the integrated compartment 5, located below the top cover plate 6. A remote control antenna 7 is installed on the outer side of the integrated compartment 5. A photovoltaic power generation panel 13 is installed on the rear surface of the integrated compartment 5 and is electrically connected to the hull 1. A propeller 12 is installed on the lower surface of the hull 1, behind the bulbous bow 9. One end of the propeller 12 is installed inside the hull 1 and houses a drive motor for propulsion. A guide vane 11 is installed on one side of the propeller 12 on the lower surface of the hull 1. The guide vane 11 is movably connected to the hull 1. A wireless network antenna 4 is installed in front of the integrated compartment 5 on the upper surface of the hull 1. A receiving mechanism 3 is set in front of the wireless network antenna 4. The receiving mechanism 3 is electrically connected to the wireless network antenna 4. The receiving mechanism 3 is movably connected to the hull 1. The receiving mechanism 3, the wireless network antenna 4, and the remote control antenna 7 are all electrically connected to each other to control the signal transmission during the shooting and scanning. A guardrail 2 is installed on the upper surface of the hull 1.

[0031] The working principle of this invention is as follows: The hull 1 is assembled by bolting the lateral buoyancy mechanism 8 on the outside. The air-blowing mechanism 806 on the lower surface of the support frame 803 inflates the inner air bladder 808 inside the buoyancy cylinder 801 through the air-blowing pipe 807 and the branch pipe 805. After the entire inner air bladder 808 is inflated, the limiting block 811 on the outside of the sealing cover 804 is engaged with the limiting slot 810, thus completing the lateral buoyancy mechanism. The hull 1 has a large overall buoyancy value, thus providing greater buoyancy on both sides to increase its stability during movement. In rough seas, the inflator 806 can continue to blow air, using a one-way valve 809 connecting the inner airbag 808 and the corrugated floats 802 to inflate the array of corrugated floats 802, thereby securing the closed cover 80, which is locked inside the limiting slot 810. After ejection, the lateral length of the entire lateral buoyancy mechanism 8 is further increased, and the buoyancy of the entire hull 1 is also increased again, which can prevent the hull 1 from capsizing in the event of large waves. The drive motor controls the propeller 12 to rotate, which stirs the water and drives the guide propeller 11 to swing, thereby controlling the movement of the hull 1. When the entire hull 1 moves at a high speed, the measuring mechanism 15 is prone to large impacts when not taking pictures. The L-shaped protective baffle 14 can be used to protect the measuring mechanism 15. When it is necessary to take pictures, the drive motor 1404 drives the gear to mesh with multiple drive gear sets 1403. Under the meshing rotation of the drive gear set 1403 and the rotating gear 1402, the movable ear plate 1401 is controlled to drive the protective baffle 14 to rotate, thereby breaking the obstruction of the protective baffle 14 on the measuring mechanism 15, so that the measuring mechanism 15 can perform normal picture processing.
