Description

Technical Field

[0001] The utility model relates to the technical field of underwater topographic surveying and mapping, and more specifically, it relates to an unmanned ship for underwater topographic surveying and mapping. Background Technique

[0002] Underwater topographic survey is a specific survey in engineering survey, which measures the plane positions and elevations of underwater points in rivers, lakes, reservoirs, harbors and coastal waters for the surveying and mapping work of drawing underwater topographic maps. The main contents are to establish a control network on land and conduct underwater topographic surveying and mapping. Underwater topographic surveying and mapping includes sounding point positioning, water depth measurement, water level observation and mapping. When conducting underwater topographic surveying and mapping, generally an unmanned ship is used to travel on the water surface, and the underwater terrain is measured by emitting sound waves.

[0003] In the related technology, through a waterproof camera, the underwater situation can be photographed during the driving process of the ship's hull, and the underwater terrain can be photographed and surveyed in cooperation with other components. By setting baffles, when encountering gravel and aquatic organisms, the inclination angle of the baffles can be used to protect the ship's hull and make it displace a certain distance in the opposite direction. After the obstruction, the baffle can return to its original position through a spring, which is convenient for the next obstruction. By setting a signal transmitter, through the cooperation between the signal transmitter and the signal receiver, the underwater terrain information photographed by the waterproof camera can be sent and received, which is convenient for accurate topographic surveying by the surveying instrument on the ground.

[0004] The above-mentioned existing technical solutions have the following defects: during the driving process of the unmanned ship, when encountering waterweeds, the waterweeds will entangle on the baffles. During the continuous driving process, the waterweeds gradually accumulate on the two baffles, resulting in the inability of the unmanned ship to continue driving. And during the driving process of the unmanned ship, when encountering a shallow water position, the unmanned ship will run aground and cannot be dealt with. Especially when running aground in the center of the water, it greatly increases the rescue difficulty of the staff. Content of the Utility Model

Obviously, the described specific implementation manners are only part of the implementation manners of the present utility model, rather than all the styles.

[0040] Embodiment 1:

[0041] Please refer to Figure 1 、 Figure 3 and Figure 6 , the present utility model provides a technical solution: an unmanned ship for underwater topographic surveying and mapping, including a hull 1, which is divided into a bow end and a stern end; the bow end includes a first deflector 7 and a second deflector 8, and the first deflector 7 and the second deflector 8 are respectively connected to both sides of the hull 1; one side of the top of the hull 1 is connected with a cutting device 10 capable of cutting. The cutting device 10 can also be a single tool for cutting or a mechanical structure similar to a saw for cutting operations, which are not all shown in the drawings. The cutting device 10 is located between the first deflector 7 and the second deflector 8; the stern end includes a top plate 27, and the top plate 27 is connected to the top of the hull 1 through a support column 26; both sides of the bottom of the hull 1 are provided with push plates 14 capable of rotating.

[0042] Specifically, a sonar ranging device 2 is connected to the bottom of the inner wall of the hull 1. A transmitting end 3 and a protective cover 4 are connected to the bottom of the hull 1. The transmitting end 3 is located inside the protective cover 4. The bottoms of both push plates 14 are lower than the bottom of the hull 1. The first deflector 7 and the second deflector 8 are inclined from both sides of the hull 1 towards the bow and are parallel to the bow direction. A diversion groove 9 is provided on one side of each of the first deflector 7 and the second deflector 8. The cutting device 10 includes a support frame 101.

A support base 106 is connected to one side of the limiting frame 102. A rotating shaft 107 is rotatably connected to the support base 106. A first gear 108 is connected to the rotating shaft 107.

Through the limiting frame 102, the cutting knife 104, the first gear 108, the motor 1010, etc., the aquatic plants on the driving route of the hull 1 are cut to avoid accumulation at the front end of the hull 1 and affecting the driving and mapping operations of the hull 1.

[0043] Embodiment 2:

[0044] Based on Embodiment 1, please refer to Figure 2 、 Figure 4 、 Figure 5 and Figure 7 .

[0045] Specifically, rolling bearing seats 11 are connected to both sides of the bottom of the hull 1. Ball bearings 12 are rotatably connected within the two rolling bearing seats 11. Support rods 13 are connected to both of the ball bearings 12. At one end of each of the two support rods 13, a push plate 14 is connected. The other ends of the two support rods 13 pass through the hull 1 and are located inside the hull 1. At the bottom of the inner wall of the hull 1, two sliding frames 15 are connected. Sliders 16 are slidably connected within the two sliding frames 15. A chute 17 is formed on one side of each of the two sliding frames 15. A limiting rod 18 is connected to one side of each of the two sliders 16. The two limiting rods 18 pass through the two chutes 17 respectively and are rotatably connected to a fixed seat 19. The two fixed seats 19 are respectively connected to the other ends of the two support rods 13. Electric push rods 20 are connected to one side of each of the two sliding frames 15. The output ends of the two electric push rods 20 are respectively connected to one side of the two sliders 16. Mounting seats 21 are connected to both sides of the inner wall of the hull 1. An engine 22 is connected to the bottom of the inner wall of the hull 1. The output end of the engine 22 is connected to a propeller 23. The propeller 23 passes through the hull 1 and is located on one side of the bottom of the hull 1. A support plate 31 is connected to one side of the top plate 27. A warning light 32 is connected to the top of the support plate 31. A processor 5 and a battery case 24 are connected to the bottom of the inner wall of the hull 1. A signal transmitter 6 is connected to the top of the processor 5. A storage battery 25 is connected within the battery case 24. A fixed frame 29 is connected to the top of the top plate 27. A solar panel 30 is connected within the fixed frame 29. An inverter 28 is connected to the bottom of the top plate 27. The solar panel 30 is electrically connected to the storage battery 25 through the inverter 28 by wires. The storage battery 25 is electrically connected to the processor 5 by wires. The processor 5 is electrically connected to the sonar ranging device 2, the signal transmitter 6, the motor 1010, the electric push rod 20, the engine 22, and the warning light 32 by wires. By adopting the above technical solution, through the rolling bearing seats 11, the push plates 14, the sliding frames 15, the electric push rods 20, etc., when the hull 1 runs aground, it blocks the hull 1, prevents the hull 1 from being completely grounded, and can push the hull 1 backward into the water. Moreover, through the cooperation of the two electric push rods 20, the hull 1 can be driven to twist when it runs aground, so as to get out of the grounded state. Through the warning light 32, during the mapping process of the hull 1 running, it warns and reminds the surrounding area. Through the solar panel 30 and the inverter 28, when the hull 1 runs for mapping operations, the storage battery 25 carried by the hull 1 is charged, greatly extending the endurance of the hull 1. Thus, when mapping some large water surfaces, the mapping can be ensured to proceed smoothly.

[0046] The working principle of the present utility model is as follows: When in use, the staff places the hull 1 into the water where underwater terrain surveying is required, and powers the processor 5 through the storage battery 25. The processor 5 works to control the hull 1. The processor 5 controls the signal transmitter 6 to work. After receiving the signal, it is transmitted to the processor 5 for processing. The processor 5 then controls the equipment to work and execute. The processor 5 controls the engine 22 to work, and the engine 22 drives the propeller 23 to rotate, driving the hull 1 to start moving forward. The processor 5 controls the sonar ranging device 2 to work. Sound waves are emitted at the transmitting end 3, and after contacting the underwater ground, they bounce back and are received by the sonar ranging device 2. By the length of time the sound waves are received, the water depth is judged, and thus the underwater terrain situation is judged. During the driving process of the hull 1, there will be waterweeds floating on the water surface, blocking the driving route of the hull 1 and affecting the hull 1's operation of surveying the underwater terrain. The processor 5 controls the motor 1010 to work. The motor 1010 drives the second gear 1011 to rotate, which meshes and drives the first gear 108 to rotate, driving the push rod 109 on one side of the first gear 108 to start rotating around the rotating shaft 107. Through the limitation of the annular frame 105, the push rod 109 slides within the annular frame 105 and pushes the annular frame 105. Through the limitation of the limiting frame 102, when the annular frame 105 is pushed, it maintains a straight up and down movement state. When the push rod 109 moves above the rotating shaft 107, the annular frame 105 rises to the highest position. When the push rod 109 rotates below the rotating shaft 107, the annular frame 105 drops to the lowest position. When the annular frame 105 rises or drops, it drives the sliding rod 103 at the bottom of the annular frame 105 to rise or drop within the limiting frame 102, thereby driving the cutting knife 104 at the bottom to rise or drop. And because the radius ratio of the first gear 108 and the second gear 1011 is 1:3, when the motor 1010 works, it will drive the cutting knife 104 to move up and down quickly. With the serrated direction of the cutting knife 104 facing the waterweeds, when contacting the waterweeds, the waterweeds are cut. After the waterweeds are cut, the waterweeds will be pushed by the first deflector 7 and the second deflector 8, causing the waterweeds to be pushed to both sides of the hull 1, so that the hull 1 can drive normally;

[0047] When the hull 1 is moving and runs aground, the bottoms of the push plates 14 on both sides of the hull 1 are lower than the hull 1 itself. By arranging the push plates 14 at the bottoms on both sides of the hull 1, the hull 1 can be blocked to prevent the hull 1 from coming into complete contact with the ground and running aground, so that the stern can still remain on the water surface. The processor 5 controls the electric push rods 20 to work, driving the two electric push rods 20 to shorten, thereby driving the sliders 16 to slide in the sliding frames 15, driving the limit rods 18 on one side of the sliders 16 to move in the chutes 17, and driving the balls 12 on the support rods 13 on both sides to rotate in the rolling bearing seats 11 through the fixed seats 19, thereby driving the push plates 14 on both sides to push the contacted ground, enabling the hull 1 to retreat and the hull 1 to enter the water again. When the contact with the ground is excessive, the processor 5 can control one of the electric push rods 20 to extend or shorten, driving the push plate 14 on one side of the hull 1 to push, and then controlling the push plate 14 on the other side to push. Repeating this way, the hull 1 is moved into the water. When the push plates 14 are not in use, the two electric push rods 20 extend to the longest, enabling the two push plates 14 to fit the hull, avoiding resistance caused by pushing the water flow during the movement of the hull 1. During the movement, the processor 5 controls the warning lights 32 to work to give a reminder to the surroundings. And during the movement, the solar panels 30 absorb solar energy and convert it into electrical energy, and through the cooperation of the inverter 28, the storage battery 25 in the hull 1 is charged, greatly extending the endurance time of the hull 1, enabling the hull 1 to perform mapping operations on a large area of water surface.

[0048] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
