Description

Technical Field

[0001] The utility model relates to the technical field of hydrological surveying and mapping, in particular to an unmanned boat for hydrological surveying and mapping. Background Art

[0002] Water area measurement includes ocean measurement, river measurement, reservoir measurement, etc. With the development of social economy, water area measurement plays a very important role in building water projects, developing water resources, and testing water quality. The vast sea area oil and gas exploitation, the port construction on the long coastline, the prevention of river siltation and scouring, the construction of hydropower stations, the design of reservoirs, etc. all require water area measurement work.

[0003] Announcement No. CN210478971U discloses a multifunctional small-sized intelligent unmanned surveying vessel, which controls the movement of the hull by driving the propeller, debugs the communication antenna through the shore-based communication system, and remotely controls the surveying vessel through the intelligent navigation system to start navigation and measurement. However, during the hull mapping process, it is inevitable that it will collide with hard objects such as reefs and driftwood in the water. Due to the lack of supporting anti-collision protection, the structure that directly collides with hard objects is very likely to be deformed and damaged, which will not only affect the hull mapping results, but also affect the safe operation of the unmanned ship. Summary of the invention

[0004] The utility model aims to solve the problem of damage caused by collision of a hull with a hard object in the prior art, and proposes an unmanned boat for hydrological surveying and mapping.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An unmanned boat for hydrological surveying and mapping comprises a hull, a support frame is mounted on the front end of the hull, four groups of threaded holes for fixedly connecting to the hull are opened on the support frame, a support plate is welded to the top end of the support frame, and a guide tube is fixedly mounted on the support plate, a support column is slidably connected in the guide tube, and a strong spring is connected between the guide tube and the support column, and the support frame is provided with an anti-collision mechanism for protecting the front end of the hull from running aground through the support plate and the support column.

[0007] Preferably, the four groups of threaded holes are symmetrically arranged on two sides of the support frame that are close to the hull, and reinforcing bolts are arranged in the threaded holes.

[0008] Preferably, the anti-collision mechanism includes an arc-shaped anti-collision frame welded on a support column, support blocks are welded inside both ends of the arc-shaped anti-collision frame, a first transmission rod is installed with a pin shaft on the support block, and the first transmission rod is movably connected with a second transmission rod installed with a pin shaft on the support frame, and connecting rods are welded at both upper and lower ends of the arc-shaped anti-collision frame, a connecting column is fixedly connected between the two groups of connecting rods, and a limiting sleeve is fixedly installed on the connecting column, a telescopic rod is slidably sleeved in the limiting sleeve, a traction connecting rod for movably pulling the telescopic rod is provided at the connecting end of the first transmission rod and the second transmission rod, and a roller corresponding to the arc-shaped anti-collision frame is rotatably installed on the telescopic rod.

[0009] Preferably, the arc-shaped anti-collision frame is connected to one end of the support column located outside the guide tube, and the arc-shaped anti-collision frame is located at the front side of the hull.

[0010] Preferably, the roller rotates to abut against the inner side of the arc-shaped anti-collision frame.

[0011] Preferably, one end of the traction link is pin-connected to the connecting end between the first transmission rod and the second transmission rod, and the other end of the traction link is pin-connected to an end of the telescopic rod away from the roller.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. The utility model arranges an arc-shaped anti-collision frame at the front end of the hull. When the hull collides with a hard object, the strong spring is squeezed, and the arc-shaped anti-collision frame moves backward. At the same time, the first transmission rod and the second transmission rod interact with each other, and the telescopic rod is driven to extend and retract linearly through the traction connecting rod. The roller rolls in contact with the inner side of the arc-shaped anti-collision frame to reversely support the arc-shaped anti-collision frame, thereby achieving the effect of protecting the hull.

[0014] 2. The utility model has four sets of threaded holes on the inclined surface where the support frame and the hull are fitted. When the anti-collision mechanism needs to be repaired and maintained, the anti-collision mechanism can be disassembled and maintained by reversely tightening the reinforcing bolts to release the connection between the two.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 3 An unmanned boat for hydrological surveying and mapping includes a hull 1, a support frame 2 is installed at the front end of the hull 1, and four groups of threaded holes 3 for fixing and connecting the hull 1 are opened on the support frame 2. The four groups of threaded holes 3 are symmetrically opened on both sides of the support frame 2 that are close to the hull 1, and reinforcing bolts are arranged in the threaded holes 3. By screwing the reinforcing bolts, the connection between the hull 1 and the support frame 2 is released, which is convenient for disassembly and maintenance of the anti-collision mechanism.

[0021] A support plate 4 is welded to the top of the support frame 2, and a guide tube 5 is fixedly installed on the support plate 4. A support column 6 is slidably connected in the guide tube 5, and a strong spring 7 is connected between the guide tube 5 and the support column 6. When the hull 1 is collided, the strong spring 7 is impacted, and the support column 6 contracts into the guide tube 5 to squeeze the strong spring 7, and the tension of the strong spring 7 can reversely support the support column 6, thereby achieving the effect of alleviating the impact force.

[0022] The support frame 2 is provided with an anti-collision mechanism for protecting the front end of the hull 1 from hitting a reef through the support plate 4 and the support column 6. Figure 2 With attached Figure 3 :

[0023] The anti-collision mechanism includes an arc-shaped anti-collision frame 8 welded on the support column 6, and an anti-collision pad is fixedly installed on the outer side of the arc-shaped anti-collision frame 8 to protect the arc-shaped anti-collision frame 8. The arc-shaped anti-collision frame 8 is connected to one end of the support column 6 located outside the guide tube 5, and the arc-shaped anti-collision frame 8 is located at the front side of the hull 1. Support blocks 9 are welded inside the two ends of the arc-shaped anti-collision frame 8, and a first transmission rod 10 is installed with a pin on the support block 9. The first transmission rod 10 is movably connected with a second transmission rod 11 installed on the support frame 2 with a pin. Connecting rods 14 are welded on the upper and lower ends of the arc-shaped anti-collision frame 8, and a connecting column 15 is fixedly connected between the two groups of connecting rods 14. A limiting sleeve 17 is fixedly installed on the connecting column 15, and a telescopic rod 12 is slidably sleeved in the limiting sleeve 17. Under the guiding and limiting action of the limiting sleeve 17, the telescopic rod 12 subjected to force is telescopically moved linearly and reciprocatingly, and a movable connecting rod 14 is arranged at the connecting end of the first transmission rod 10 and the second transmission rod 11. The traction link 16 of the dynamic traction telescopic rod 12, one end of the traction link 16 is pin-connected with the connecting end between the first transmission rod 10 and the second transmission rod 11, and the other end of the traction link 16 is pin-connected with an end of the telescopic rod 12 away from the roller 13, and the arc-shaped anti-collision frame 8 moving forward and backward is pulled or pressed on the telescopic rod 12 by the first transmission rod 10 and the second transmission rod 11, so that the telescopic rod 12 drives the roller 13 to move synchronously, and the roller 13 corresponding to the arc-shaped anti-collision frame 8 is rotatably installed on the telescopic rod 12, and the roller 13 rotates to contact the inner side of the arc-shaped anti-collision frame 8. When hit, the first transmission rod 10 and the second transmission rod 11 are closed and deflected, and the telescopic rod 12 is squeezed and slides in the connecting column 15, and the roller 13 slides against the inner side of the arc-shaped anti-collision frame 8 to reversely support the arc-shaped anti-collision frame 8 to prevent the arc-shaped anti-collision frame 8 from further moving backward to squeeze the hull 1, thereby achieving the auxiliary effect of alleviating the impact force.

[0024] It should be noted that the specific model and specifications of the hull 1 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0025] The functional principle of the utility model can be explained through the following operation modes:

[0026] When the ship 1 is hit, the arc-shaped anti-collision frame 8 is squeezed inward, the support column 6 is compressed into the guide tube 5, and the strong spring 7 is squeezed at the same time;

[0027] The arc-shaped anti-collision frame 8 squeezes the first transmission rod 10 and the second transmission rod 11, so that the first transmission rod 10 and the second transmission rod 11 are closed and deflected, and the two squeeze the telescopic rod 12 through the traction connecting rod 16, so that the telescopic rod 12 moves telescopically guided by the limiting sleeve 17, and the telescopic rod 12 drives the roller 13 to rotate against the inner side of the arc-shaped anti-collision frame 8, so as to provide reverse support for the arc-shaped anti-collision frame 8.

[0028] When the anti-collision mechanism needs to be maintained, the support frame 2 can be disassembled by screwing the reinforcing bolts in the threaded holes 3 .

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
