Description

Technical Field

[0001] This invention relates to the field of intelligent watercraft equipment technology, and more specifically, to a multifunctional autonomous operating platform. Background Technology

[0002] With the increasing demands in areas such as water resource protection, waterway engineering surveys, and emergency rescue, waterborne operation equipment faces severe challenges in multi-task coordination and adaptation to complex environments. In the field of waterborne operations, unmanned surface vessels (USVs), with their advantage of requiring no on-site human control, are widely used in various scenarios such as hydrological monitoring, waterway inspection, and water quality sampling. Their hull structures are generally characterized by long length and narrow width. Because USVs lack the ability for real-time human intervention to adjust their attitude, they must effectively withstand the impact of wind and waves from all directions to ensure hull stability and avoid excessive rolling, loss of control, or even capsizing when operating in complex water environments. Therefore, installing buoys on the sides of the hull has become the mainstream method in current technology for ensuring the navigation stability of USVs.

[0003] While installing pontoon structures on the sides of the hull improves the unmanned surface vessel's (USV) ability to withstand wind and waves, there is a conflict between the need for wind and wave resistance and the USV's navigation efficiency. That is, the higher the need for wind and wave resistance, the larger the volume of the pontoons required (in order to provide sufficient buoyancy to balance the impact of wind and waves). However, large-volume pontoons will significantly increase the forward resistance of the USV, thereby affecting its speed and endurance, which is not conducive to the USV's efficient completion of various water operations.

[0004] In view of this, we propose a multifunctional autonomous operating platform to improve the above-mentioned shortcomings. Summary of the Invention

[0005] This invention provides a multifunctional autonomous operating platform that solves the conflict between the need for wind and wave resistance and the navigation efficiency of unmanned surface vessels.

[0006] To achieve the above objectives, the multi-functional autonomous operating platform includes stabilization components mounted on both sides of the unmanned surface vessel; The stabilizing component includes a rotating bolt that is slidably connected to the unmanned surface vessel in the vertical direction. The rotating bolt is fixed in a horizontal direction relative to the unmanned surface vessel. A rotating cylinder is rotatably connected to the bottom of the rotating bolt. The axis of the rotating cylinder is parallel to the forward direction of the unmanned surface vessel. A float is provided inside the rotating bolt and the float is always located at the top inside the rotating cylinder. The rotating drum slides relative to the unmanned surface vessel (USV) to absorb the energy generated by vertical waves. When the USV is subjected to lateral impact from waves, the rotating drum rotates to offset the impact energy. The float is always located above the rotating drum to increase the resistance when the rotating drum moves up and down and to reduce the resistance when the rotating drum moves forward.

[0007] In the above technical solution, the pontoon is always located in the upper part of the rotating cylinder under the action of buoyancy, that is, a space is left in the lower part of the rotating cylinder for water flow. This provides sufficient drainage resistance when the unmanned surface vessel (USV) sways up and down with the water flow, thereby improving the stability of the USV. Furthermore, the water flow space left in the lower part of the rotating cylinder reduces the water flow resistance encountered by the rotating cylinder while it is following the USV.

[0008] Based on this, the stabilizing component includes a limiting bolt, which is fixedly connected to the side of the unmanned surface vessel. A sliding rod is slidably connected inside the limiting bolt in the vertical direction, and the bottom of the sliding rod is fixedly connected to a rotating bolt.

[0009] A limit cap is fixedly connected to the top of the slide rod, and a spring is sleeved around the slide rod between the top of the limit bolt and the bottom of the limit cap.

[0010] Furthermore, a waterproof shell is fixedly connected to the top of the limiting bolt around the limiting cap. The waterproof shell is used to allow the limiting cap to slide freely inside while isolating it from external moisture.

[0011] With this design, when the unmanned surface vessel (USV) is operating on the water, the floats, under the influence of the vertical energy waves of the waves, transfer the impact force to the sliding rod through the rotating cylinder. The sliding rod and the USV are connected elastically rather than rigidly. Therefore, the USV's vertical movement on the water is greater than that of the rotating cylinder and floats. This is because part of the vertical impact energy in the waves is converted into the work done by the rotating cylinder and floats in overcoming water resistance, and another part is converted into the elastic potential energy generated by the spring deformation and stored. Finally, the remaining energy is directly transferred to the USV, thus ensuring the stability of the USV when operating on the water.

[0012] In another technical solution, the bottom of the rotating bolt is fixedly connected to the main rod, the rotating cylinder is rotatably connected to the periphery of the main rod, and the float is rotatably connected to the periphery of the main rod, and the rotation of the rotating cylinder and the float around the axis are independent of each other.

[0013] Furthermore, multiple connecting rods are fixedly connected to the end of the rotating drum, and a rotating sleeve is fixedly connected to the end of the multiple connecting rods away from the end of the rotating drum. The rotating sleeve is rotatably connected to the main rod.

[0014] Furthermore, the pontoon has a semi-circular longitudinal section, a limiting sleeve is provided at the axis of the pontoon, the limiting sleeve is rotatably connected to the main rod, and the arc-shaped outer wall of the pontoon fits against the inner wall of the rotating cylinder.

[0015] Preferably, the float is a hollow, thin-walled structure, used to increase the water resistance encountered during the up-and-down movement of the rotating drum.

[0016] In addition, multiple drive plates are fixedly connected to the periphery of the rotating drum. The length distribution direction of the multiple drive plates coincides with the axis of the rotating drum, and the width direction of the drive plates coincides with the radius of the longitudinal section of the rotating drum.

[0017] Furthermore, one side of the flat surface of the float and the inner wall of the rotating cylinder form a water passage cavity. When the rotating cylinder rotates, the float is always located in the upper part of the rotating cylinder under the action of buoyancy. The water passage cavity is used to reduce the resistance of the float when it follows the unmanned surface vessel.

[0018] As can be seen from the above scheme, when the water flows from the side of the unmanned surface vessel (USV) to the USV, the waves will first come into contact with the rotating cylinder. The drive plate rotates around the main rod under the push of the waves. When the drive plate rotates, it needs to overcome the resistance of the water. Therefore, the lateral impact force of the waves is converted into the work done by the drive plate to overcome the resistance of the water when it rotates, thereby reducing the impact force of the lateral energy of the waves on the USV.

[0019] Based on the above description, the beneficial effects of the present invention compared with the prior art are as follows: When water flows from the side of the unmanned surface vessel (USV) towards the USV, the waves will first come into contact with the rotating cylinder. The drive plate rotates around the main rod under the push of the waves. When the drive plate rotates, it needs to overcome the resistance of the water. Therefore, the lateral impact force of the waves is converted into the work done by the drive plate to overcome the resistance of the water when it rotates, thereby reducing the impact force of the lateral energy of the waves on the USV. Furthermore, regardless of how the rotating drum rotates under the drive plate, the float remains at the top of the rotating drum due to the buoyancy of the water. That is, the water passage cavity is always located at the bottom of the rotating drum. Therefore, as the rotating drum follows the unmanned surface vessel, the water flow will pass through the water passage cavity, thereby reducing the resistance caused by the water flow to the unmanned surface vessel during the journey of the rotating drum and float.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] In existing technologies, the ability of unmanned surface vessels (USVs) to withstand wind and waves is improved by setting up pontoon structures on the sides of the hull. However, there is a conflict between the need for wind and wave resistance and the efficiency of USV navigation. That is, the higher the need for wind and wave resistance, the larger the volume of the pontoon needs to be (in order to provide sufficient buoyancy to balance the impact of wind and waves). However, large-volume pontoons will significantly increase the forward resistance of USV navigation, thereby affecting navigation speed and endurance, which is not conducive to USVs efficiently completing various water operations.

[0024] Please see Figures 1-4 In order to solve the problems existing in the prior art, the purpose of the present invention is to provide a multifunctional autonomous operation platform, the autonomous operation platform including stabilization components 110 disposed on both sides of the unmanned surface vessel 100; The stabilizing assembly 110 includes a rotating bolt 210 that is slidably connected to the unmanned surface vessel 100 in the vertical direction. The rotating bolt 210 is fixed in a horizontal direction relative to the unmanned surface vessel 100. A rotating cylinder 220 is rotatably connected to the bottom of the rotating bolt 210. The axis of the rotating cylinder 220 is parallel to the forward direction of the unmanned surface vessel 100. A float 230 is provided inside the rotating bolt 210 and the float 230 is always located at the top inside the rotating cylinder 220. The rotating drum 220 slides relative to the unmanned surface vessel 100 to absorb the energy generated by vertical waves. When the unmanned surface vessel 100 is subjected to lateral impact from waves, the rotating drum 220 rotates to offset the impact energy. The float 230 is always located above the rotating drum 220 to increase the resistance when the rotating drum 220 moves up and down and to reduce the resistance when the rotating drum 220 moves forward.

[0025] During operation on the water surface, the rotating cylinder 220 and the floating cylinder 230 float together under the buoyancy of the water on the floating cylinder 230. When the vertical energy wave in the wave impacts the unmanned surface vessel 100, the rotating cylinders 220 on both sides of the unmanned surface vessel 100 are driven by the wave impact and move up and down relative to the unmanned surface vessel 100. Due to the large volume of the rotating cylinders 220 and the floating cylinders 230, the resistance they experience when rising and falling and discharging water on the water surface will be large. In other words, when the vertical energy wave in the wave acts on the unmanned surface vessel 100, a portion of it will be converted into the work done by the rotating cylinders 220 and the floating cylinders 230 to overcome water resistance during their up and down movement. Therefore, the impact of the wave on the unmanned surface vessel 100 will be reduced, thereby improving the stability of the unmanned surface vessel 100 during operation on the water surface.

[0026] Not only vertical energy waves exist in the waves, but also horizontal energy waves. When the waves impact the side of the unmanned surface vessel 100, the waves will first come into contact with the rotating cylinders 220 on both sides of the unmanned surface vessel 100. Under the action of the horizontal waves, the waves push the rotating cylinders 220 to rotate around the axis. The rotating cylinders 220 flip over to overcome the resistance of the water and do work, thereby weakening the impact force of the horizontal waves on the unmanned surface vessel 100.

[0027] To improve the stability of the unmanned surface vessel 100, the float 230 typically needs to be made larger. However, this would increase the resistance from water flow during the unmanned surface vessel 100's navigation. In this application, the float 230, under the influence of buoyancy, is always located in the upper part of the rotating cylinder 220. This means that space is left in the lower part of the rotating cylinder 220 for water flow, thus providing sufficient drainage resistance when the unmanned surface vessel 100 sways with the water flow, thereby improving its stability. Furthermore, the water flow space in the lower part of the rotating cylinder 220 reduces the water flow resistance experienced by the rotating cylinder 220 while it is navigating with the unmanned surface vessel 100.

[0028] For a better understanding of the above content, please refer to [link / reference]. Figure 5 The stabilizing component 110 includes a limiting bolt 200, which is fixedly connected to the side of the unmanned surface vessel 100. A sliding rod 202 is slidably connected inside the limiting bolt 200 in the vertical direction, and the bottom of the sliding rod 202 is fixedly connected to a rotating bolt 210.

[0029] Based on the above, a limit cap 203 is fixedly connected to the top of the slide rod 202, and a spring 204 is sleeved around the slide rod 202 between the top of the limit bolt 200 and the bottom of the limit cap 203.

[0030] Furthermore, a waterproof shell 201 is fixedly connected to the top of the limiting bolt 200 around the limiting cap 203. The waterproof shell 201 is used to allow the limiting cap 203 to slide freely inside while isolating it from external moisture.

[0031] It should be noted that when the unmanned surface vessel 100 is operating on the water surface, the float 230, under the action of the vertical energy wave of the wave, transmits the impact force to the slide bar 202 through the rotating cylinder 220. The slide bar 202 and the unmanned surface vessel 100 are elastically connected rather than rigidly connected. Therefore, the amplitude of the up-and-down movement of the unmanned surface vessel 100 on the water surface is greater than that of the rotating cylinder 220 and the float 230. This is because part of the vertical impact energy in the wave is converted into the work done by the rotating cylinder 220 and the float 230 in overcoming the water resistance and moving up and down, and another part is converted into the elastic potential energy generated by the deformation of the spring 204 and stored. Finally, the remaining part of the energy is directly transferred to the unmanned surface vessel 100, thereby ensuring the stability of the unmanned surface vessel 100 when operating on the water surface.

[0032] Next, as Figures 6-9 As shown, the bottom of the rotating bolt 210 is fixedly connected to the main rod 211, the rotating cylinder 220 is rotatably connected to the periphery of the main rod 211, and the float 230 is rotatably connected to the periphery of the main rod 211. The rotation of the rotating cylinder 220 and the float 230 around the axis are independent of each other.

[0033] Furthermore, multiple connecting rods 212 are fixedly connected to the end of the rotating drum 220, and a rotating sleeve 213 is fixedly connected to the end of the multiple connecting rods 212 away from the end of the rotating drum 220. The rotating sleeve 213 is rotatably connected to the main rod 211.

[0034] Furthermore, the longitudinal section of the float 230 is semi-circular, and a limiting sleeve 231 is provided at the axis of the float 230. The limiting sleeve 231 is rotatably connected to the main rod 211, and the arc-shaped outer wall of the float 230 fits against the inner wall of the rotating cylinder 220.

[0035] Preferably, the float 230 is a hollow thin-walled structure, used to increase the water resistance encountered by the rotating drum 220 during its up-and-down movement.

[0036] Based on the above explanation, the following will further combine... Figure 10 and Figure 11 Explanation of the preferred effect of the float 230 always being located in the upper part of the rotating drum 220: Multiple drive plates 221 are fixedly connected to the periphery of the rotating drum 220. The length distribution direction of the multiple drive plates 221 coincides with the axis of the rotating drum 220, and the width direction of the drive plates 221 coincides with the radius of the longitudinal section of the rotating drum 220.

[0037] Furthermore, one side of the flat surface of the float 230 and the inner wall of the rotating cylinder 220 form a water passage cavity 222. When the rotating cylinder 220 rotates, the float 230 is always located in the upper part of the rotating cylinder 220 under the action of buoyancy. The water passage cavity 222 is used to reduce the resistance of the float 230 when it follows the unmanned surface vessel 100.

[0038] In other words, when water flows from the side of the unmanned surface vessel 100 to the unmanned surface vessel 100, the waves will first come into contact with the rotating cylinder 220. The drive plate 221 rotates around the main rod 211 under the push of the waves. When the drive plate 221 rotates, it needs to overcome the resistance of the water. Therefore, the lateral impact force of the waves is converted into the work done by the drive plate 221 in overcoming the resistance of the water when it rotates, thereby reducing the impact force of the lateral energy of the waves on the unmanned surface vessel 100.

[0039] During this period, no matter how the rotating drum 220 rotates under the drive of the drive plate 221, the float 230 is always located at the top inside the rotating drum 220 under the buoyancy of the water, that is, the water passage cavity 222 is always located at the lower part inside the rotating drum 220. Therefore, during the process of the rotating drum 220 following the unmanned surface vessel 100, the water flow will pass through the water passage cavity 222, thereby reducing the resistance caused by the water flow to the unmanned surface vessel 100 during the process of the rotating drum 220 and the float 230 following the unmanned surface vessel 100.

[0040] When the unmanned surface vessel 100 operates on the water surface, the float 230, under the buoyancy of the water, drives the rotating cylinder 220 to float together with the float 230 on the water surface. The stabilization component 110 achieves a dual improvement in the stability and navigation efficiency of the unmanned surface vessel 100 through the synergistic effect of "vertical wave energy absorption, lateral wave energy cancellation, and reduction of navigation resistance". The specific working principle is as follows: Firstly, there is the resistance to vertical wave impact: When the vertical energy wave in the wave impacts the unmanned surface vessel 100, the rotating cylinders 220 on both sides of the unmanned surface vessel 100 are the first to be impacted by the wave, driving the rotating cylinders 220 and the floats 230 to move vertically relative to the unmanned surface vessel 100 along the sliding rod 202. Since the floats 230 are hollow thin-walled structures and the overall volume of the rotating cylinders 220 and the floats 230 is relatively large, they will experience significant water resistance during vertical movement and drainage. This causes part of the energy of the vertical wave to be converted into work done by the rotating cylinders 220 and the floats 230 in overcoming water resistance during vertical movement. At the same time, the sliding rod 202 and the unmanned surface vessel 100 are connected elastically, rather than rigidly, by the spring 204. Another part of the energy of the vertical wave is converted into elastic potential energy generated by the deformation of the spring 204 and stored. Only the remaining energy is transferred to the unmanned surface vessel 100, effectively reducing the amplitude of the vertical rise and fall of the unmanned surface vessel 100 and significantly improving its vertical operational stability. Among them, the hollow thin-walled structure of the float 230 further increases the water resistance when the rotating drum 220 moves up and down, and improves the absorption effect of vertical wave energy. After the wave impact disappears, the spring 204 can drive the slide bar 202, the rotating drum 220 and the float 230 to reset, ensuring that the stabilizing component 110 continues to play its role.

[0041] Secondly, there is the resistance to lateral wave impact: When waves impact the side of the unmanned surface vessel 100, the waves first contact the drive plate 221 around the outer perimeter of the rotating cylinder 220. Under the action of the lateral impact force, the drive plate 221 drives the rotating cylinder 220 to rotate around the main rod 211. During the rotation of the rotating cylinder 220, both it and the drive plate 221 need to overcome water resistance, so that the impact energy of the lateral waves is gradually consumed, thereby significantly weakening the lateral impact force transmitted to the unmanned surface vessel 100. This avoids the problem of excessive rolling and loss of attitude of the unmanned surface vessel 100 due to lateral impact, ensuring its lateral operational stability. During this process, regardless of the rotation angle of the rotating cylinder 220, the float 230 always remains at the top inside the rotating cylinder 220 under the action of buoyancy, ensuring the structural integrity of the water passage cavity 222 and not affecting the effect of offsetting the lateral wave energy.

[0042] Finally, regarding the reduction of navigation resistance: In existing technologies, to improve wind and wave resistance, the volume of the float 230 needs to be increased, which leads to increased navigation resistance and decreased navigation efficiency. In this invention, the float 230 is always located at the top inside the rotating cylinder 220, and the water passage cavity 222 formed by the float 230 and the inner wall of the rotating cylinder 220 provides a smooth passage for water flow. When the unmanned surface vessel 100 is navigating normally, the water flow can smoothly pass through the water passage cavity 222 at the bottom of the rotating cylinder 220, effectively reducing the obstruction of the water flow by the rotating cylinder 220 and the float 230, reducing the forward resistance of the unmanned surface vessel 100, and ensuring that its navigation speed and endurance are not affected. At the same time, the semi-circular structure of the float 230 and the streamlined design of the rotating cylinder 220 further optimize the hydrodynamic characteristics, reduce wave-making resistance and viscous pressure resistance during navigation, and achieve a balance between wind and wave resistance and navigation efficiency.

[0043] In summary, this invention effectively offsets the impact energy of vertical and lateral waves through "resistance consumption and potential energy storage," and at the same time, through the positional design of the float 230 and the structural optimization of the water passage cavity 222, it resolves the contradiction between wind and wave resistance and navigation efficiency in the prior art, ensuring that the unmanned surface vessel 100 can stably complete its waterborne operations.
