An unmanned ship for underwater topographic mapping

Abstract

This utility model relates to the field of underwater topographic mapping technology and discloses an unmanned underwater vehicle (UAV) for underwater topographic mapping. The UAV includes a hull with a through-slot at its bottom, which is not connected to the interior of the hull. A plate-type airbag is installed within the through-slot, and a hollow plate is fixedly installed at the bottom of the airbag. Wheels are mounted on the bottom of the hollow plate. The air inlet and outlet ports of the airbag extend into the hull. A small air pump is installed inside the hull, and its output is connected to an air duct. This design adds a moving and lifting structure. Because the inflated airbag can lift the hull, it effectively avoids the problem of the UAV having a deep draft. Even on uneven water surfaces, the draft of the entire UAV can be adjusted by inflating and deflating the airbag, thus preventing capsizing.

Description

Technical Field

[0001] This utility model relates to the field of underwater topographic mapping technology, specifically to an unmanned underwater topographic mapping vessel. Background Technology

[0002] Underwater topographic surveying is a specific type of engineering surveying that measures the horizontal position and elevation of points on the seabed of rivers, lakes, reservoirs, harbors, and nearshore waters to create underwater topographic maps. Its main components are establishing a control network on land and conducting underwater topographic mapping. Underwater topographic mapping includes sounding point location, depth measurement, water level observation, and mapping. Generally, unmanned surface vessels (USVs) are used for underwater topographic mapping, emitting sound waves to measure the underwater terrain. However, existing USVs have limitations due to their draft, making it impossible to reach some shallow areas and mudflats, resulting in incomplete coverage of the surveyed area. They are also prone to running aground, becoming unable to return, and colliding with obstacles can damage the hull and equipment.

[0003] Therefore, some manufacturers will install wheels or tracks inside the unmanned surface vessel (USV) for movement. To ensure normal use, they will also equip it with a corresponding lifting structure. When it reaches shallow water, the lifting structure will push the moving parts out so that they can contact the bottom of the water, thus avoiding the problem of running aground. However, since USVs are mainly used for surveying and mapping tasks, their size is not very large. If too many lifting and moving structures are installed, it is easy to cause the entire hull to have an excessively deep draft. When the water is not calm, it may cause water to enter the hull or even capsize. Utility Model Content

[0004] The purpose of this invention is to provide an unmanned underwater vehicle for topographic mapping to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an unmanned underwater vehicle (UAV) for underwater topographic mapping, comprising a hull, a through groove at the bottom of the hull that is not connected to the interior of the hull, a plate-type airbag within the through groove, a hollow plate fixedly mounted at the bottom of the plate-type airbag, wheels at the bottom of the hollow plate, an air inlet and an air outlet of the plate-type airbag extending into the hull, a small air pump within the hull, an air duct connected to the output end of the small air pump, the end of the air duct away from the small air pump connected to the air inlet, and solenoid valves at the points where the air inlet and air outlet connect to the plate-type airbag.

[0006] Furthermore, the unmanned vessel is equipped with a battery, a hull drive system, and a topographic mapping instrument. The topographic mapping instrument is located at the bow, and its detection end extends out of the hull. The battery supplies power to the hull drive system, a small air pump, a solenoid valve, and the topographic mapping instrument via a wiring harness.

[0007] Furthermore, the top of the unmanned vessel is covered with a shielding cover, and a solar panel is fixedly installed on the top of the shielding cover. The solar panel is electrically connected to a battery via a wiring harness.

[0008] Furthermore, a signal transceiver is fixedly installed inside the hull of the unmanned vessel. The top of the signal transceiver passes through the cover plate, and the signal transceiver is electrically connected to the battery via a wiring harness.

[0009] Furthermore, a limiting guide rod is fixedly installed inside the through groove, and a connecting frame is fixedly sleeved on the outer wall of the hollow plate, with the connecting frame slidably sleeved on the limiting guide rod.

[0010] Furthermore, the unmanned vessel is equipped with push plates on both sides of the bow, and the push plates are fixedly connected to the outer wall of the unmanned vessel hull via elastic connecting columns.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Upon reaching shallow water, a small air pump generates airflow, which flows sequentially through the air duct, air inlet, and solenoid valve into the plate-type airbag. This causes the plate-type airbag to inflate, pushing the hollow plate downwards, which in turn moves the wheels downwards. As the plate-type airbag inflates, the buoyancy of the entire unmanned vessel increases, causing the hull to float. This effectively prevents the unmanned vessel from touching the bottom. Furthermore, when the wheels come into contact with the bottom, they also support the hull, further preventing the unmanned vessel from touching the bottom.

[0013] 2. This design adds a moving structure and a lifting structure. However, because the inflatable plate airbag can lift the hull of the unmanned boat, it can effectively avoid the problem of the unmanned boat having a deep draft. When the water surface is uneven, the draft of the entire unmanned boat can also be adjusted by inflating and deflating the plate airbag, thereby avoiding the problem of the boat capsizing.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1-5This utility model provides a technical solution: an underwater topographic mapping unmanned surface vessel (USV), comprising a USV hull 1, a through groove 3 at the bottom of the USV hull 1 (not connected to the interior of the USV hull 1), a plate-type airbag 5 disposed within the through groove 3, a hollow plate 6 fixedly mounted at the bottom of the plate-type airbag 5, and wheels 7 disposed at the bottom of the hollow plate 6, the air inlet 14 and exhaust 15 of the plate-type airbag 5 extending into the USV hull 1, a small air pump 12 disposed within the USV hull 1, the output end of the small air pump 12 connected to an air guide pipe 13, the end of the air guide pipe 13 away from the small air pump 12 connected to the air inlet 14, and solenoid valves 16 disposed at the points where the air inlet 14 and exhaust 15 connect to the plate-type airbag 5, the small air pump 12 operating to generate airflow when reaching shallow water areas, the airflow... The air flows sequentially through the air duct 13, air inlet 14, and solenoid valve 16 into the plate-type airbag 5, causing the plate-type airbag 5 to inflate. This pushes the hollow plate 6 downward, which in turn drives the wheels 7 downward. As the plate-type airbag 5 inflates, the buoyancy of the entire unmanned vessel increases, causing the hull 1 of the unmanned vessel to float upward, effectively preventing the hull 1 from touching the bottom. When the wheels 7 come into contact with the bottom, they can also support the hull 1 of the unmanned vessel, further preventing the hull 1 from touching the bottom. This design adds a moving structure and a lifting structure. However, because the inflated plate-type airbag 5 can lift the hull 1 of the unmanned vessel, it can effectively prevent the hull 1 from having a deep draft. When the water surface is uneven, the draft of the entire unmanned vessel can be adjusted by inflating and deflating the plate-type airbag 5, thereby preventing the vessel from capsizing.

[0022] The unmanned vessel hull 1 is equipped with a battery 10, a hull drive system 4, and a topographic mapping instrument 2. The topographic mapping instrument 2 is located at the bow, and the detection end of the topographic mapping instrument 2 extends from inside the hull 1. The battery 10 supplies power to the hull drive system 4, a small air pump 12, a solenoid valve 16, and the topographic mapping instrument 2 through a wiring harness. The topographic mapping instrument 2 is used to map the underwater terrain, the battery 10 supplies power to the electronic devices, and the hull drive system 4 is used to drive the unmanned vessel to move.

[0023] The top of the unmanned boat hull 1 is covered with a shielding cover 17, and a solar panel 18 is fixedly installed on the top of the shielding cover 17. The solar panel 18 is electrically connected to the battery 10 through a wiring harness. The shielding cover 17 is set to shield the internal structure of the unmanned boat hull 1 to prevent rainwater or sloshing water from entering the unmanned boat hull 1.

[0024] A signal transceiver 11 is fixedly installed inside the hull 1 of the unmanned vessel. The top of the signal transceiver 11 passes through the cover plate 17. The signal transceiver 11 is electrically connected to the battery 10 through a wiring harness. The signal transceiver 11 is used for signal transmission and reception.

[0025] A limiting guide rod 9 is fixedly installed inside the through groove 3. A connecting frame 8 is fixedly sleeved on the outer wall of the hollow plate 6. The connecting frame 8 is slidably sleeved on the limiting guide rod 9. The connecting frame 8 and the limiting guide rod 9 are set to guide the hollow plate 6 so that the hollow plate 6 can only be moved up and down by the plate airbag 5.

[0026] The unmanned vessel hull 1 has push plates 19 on both sides of the bow. The push plates 19 are fixedly connected to the outer wall of the unmanned vessel hull 1 via elastic connecting columns 20. The push plates 19 are used to push debris on the water surface to prevent debris from obstructing the movement of the unmanned vessel. Since the push plates 19 are connected to the unmanned vessel hull 1 via elastically deformable connecting columns 20, the push plates 19 are subjected to water resistance when the unmanned vessel moves, causing the elastic connecting columns 20 to be squeezed. After the unmanned vessel stops, the water resistance on the push plates 19 decreases, and the elastic connecting columns 20 push the push plates 19 to move, causing the push plates 19 to push away the debris accumulated near the bow.

[0027] Working principle: When in use, the unmanned vessel hull 1 is placed in the water. During the movement of the unmanned vessel hull 1, the topographic mapping instrument 2 can map the underwater topography. When it reaches the shallow water area, the small air pump 12 works to generate airflow. The airflow flows through the air duct 13, the air inlet 14, and the solenoid valve 16 into the plate-type airbag 5, causing the plate-type airbag 5 to expand. This pushes the hollow plate 6 downward, which in turn drives the wheels 7 downward. As the plate-type airbag 5 expands, the buoyancy of the entire unmanned vessel increases, causing the unmanned vessel hull 1 to float. This effectively avoids the problem of the unmanned vessel hull 1 touching the bottom. Furthermore, when the wheels 7 contact the bottom of the water, they can also support the unmanned vessel hull 1, further preventing the unmanned vessel hull 1 from touching the bottom.

[0028] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
