Description

Technical Field

[0001] This utility model relates to the field of unmanned vessel technology, specifically to a power device for an unmanned vessel. Background Technology

[0002] Unmanned surface vessels (USVs) are vessels that do not require direct human control. They navigate using automation technology, remote control, or artificial intelligence systems. During operation, USVs require a drive unit to propel the equipment and provide power for their movement.

[0003] Typically, unmanned surface vessels (USVs) rely on motors to drive propellers to provide propulsion during operation. However, the propellers are submerged in water containing weeds and other debris. When these weeds become entangled around the propeller, they can jam, preventing it from starting. Furthermore, since there are no crew members on the USV, it is impossible to clear the clogged weeds in time, thus affecting the USV's operational efficiency. Therefore, we propose a new power system for USVs. Utility Model Content

[0004] To address the shortcomings of existing unmanned surface vessel (USV) propulsion systems, this invention provides a propulsion system for USVs that features a diverter plate at the front of a support frame. This diverter plate reduces water resistance and blocks obstacles in the water, improving the stability of the equipment during operation. Simultaneously, a protective cover is located at the rear of the support frame, further protecting the spiral-shaped exterior and improving the propeller's operating efficiency. This invention solves the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a power unit for an unmanned surface vessel, including a bracket, an arc-shaped toothed plate fixedly connected to the rear end of the bracket, a rotating shaft limiting sleeve fixedly connected to the middle of the bracket, a protective cover fixedly connected to the front end of the rotating shaft limiting sleeve, a third helical gear and a fourth helical gear movably sleeved inside the arc-shaped toothed plate, auxiliary gears meshing with both sides of the fourth helical gear, a fifth helical gear meshing with one side of the auxiliary gear, a second rotating shaft fixed to one end of the output shaft of the fifth helical gear, a sixth helical gear meshing with the rear end of the third helical gear, a rotating rod fixedly connected to the middle of the sixth helical gear, a slide rail movably sleeved outside the arc-shaped toothed plate, and a diverter plate fixedly connected to the outside of the slide rail.

[0006] Preferably, the end of the output shaft of the fourth helical gear is fixedly connected to a first rotating shaft, the first rotating shaft passes through the interior of the fifth helical gear and the second rotating shaft, and the ends of the first rotating shaft and the fifth helical gear are both equipped with propellers, which are installed inside the protective cover.

[0007] Preferably, the fourth helical gear, the auxiliary gear, and the fifth helical gear are all installed inside the bracket. Two sets of auxiliary gears are installed, and the auxiliary gears mesh with the fourth helical gear and the fifth helical gear respectively.

[0008] Preferably, a first helical gear is installed in the middle of the rotating rod, a mounting bracket is installed at the upper end of the bracket, a first motor is installed inside the mounting bracket, a second gear installed on the output shaft of the first motor meshes with the first helical gear, and the rotating rod is installed on the inner side of the arc-shaped toothed plate.

[0009] Preferably, the arc-shaped toothed plate and the slide rail are arc-shaped, and a second motor is installed in the middle of the diverter plate. A gear installed at one end of the output shaft of the second motor meshes with the outside of the arc-shaped toothed plate.

[0010] Preferably, a fixing frame is fixedly connected to the side of the slide rail, the fixing frame is installed at the rear end of the unmanned vessel, the entire support is submerged in the water, and the outside of the diversion plate is conical.

[0011] Preferably, both the first motor and the second motor are located at the upper end of the fixed frame, and both the first motor and the second motor are equipped with wireless monitoring devices inside, while both the first motor and the second motor are provided with waterproof layers on the outside.

[0012] Compared with existing unmanned surface vessel (USV) propulsion systems, this invention has the following advantages:

[0013] 1. The power unit of this unmanned boat can control the position of the arc-shaped toothed plate inside the slide rail by starting the second motor and engaging with the outside of the arc-shaped toothed plate. That is, the angles of the two sets of rotating shaft limit sleeves can be adjusted synchronously, so as to maintain the stability of the unmanned boat during the operation. Moreover, the equipment only uses two sets of drive devices, both of which are set at the top, improving the convenience of unmanned control.

[0014] 2. The power unit of the unmanned vessel is set on the side of the support through a diverter plate. The outside of the diverter plate is conical, which reduces water resistance during the operation of the equipment. At the same time, the diverter plate pushes away impurities and aquatic plants in the water, preventing aquatic plants from moving into the propeller and affecting its performance. In addition, a protective cover is installed on the outside of the propeller to further improve the protection performance. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A power unit for an unmanned surface vessel includes a support frame 1. An arc-shaped toothed plate 2 is fixedly connected to the rear end of the support frame 1. A rotating shaft limiting sleeve 3 is fixedly connected to the middle of the support frame 1, limiting the transmission structure. A protective cover 4 is fixedly connected to the front end of the rotating shaft limiting sleeve 3, fitting around the propeller to improve its protection. A third helical gear 5 and a fourth helical gear 6 are movably fitted inside the arc-shaped toothed plate 2. An auxiliary gear 8 meshes with both sides of the fourth helical gear 6, with one side of the auxiliary gear 8 meshing with... Equipped with a fifth helical gear 9, one end of the output shaft of the fifth helical gear 9 is fixed to a second rotating shaft 10. Under the auxiliary transmission of the auxiliary gear 8, the fifth helical gear 9 is controlled to rotate in the opposite direction, that is, the first rotating shaft 7 and the second rotating shaft 10 rotate in opposite directions, reducing the torsional force and improving the stability of the equipment. The rear end of the third helical gear 5 is meshed with a sixth helical gear 12. A rotating rod 11 is fixedly connected to the middle of the sixth helical gear 12. A slide rail 15 is movably sleeved on the outside of the arc-shaped toothed plate 2. A diverter plate 16 is fixedly connected to the outside of the slide rail 15.

[0023] Please see Figure 5The first rotating shaft 7 is fixedly connected to the end of the output shaft of the fourth helical gear 6. The first rotating shaft 7 passes through the interior of the fifth helical gear 9 and the second rotating shaft 10. Propellers are installed at the ends of the first rotating shaft 7 and the fifth helical gear 9. The propellers are installed inside the protective cover 4. The first rotating shaft 7 passes through the interior of the second rotating shaft 10 and the fifth helical gear 9. That is, when the first rotating shaft 7 rotates, it will not interfere with the rotation of the fifth helical gear 9 and the second rotating shaft 10. In addition, the second rotating shaft 10 and the first rotating shaft 7 drive the propeller to rotate, providing power for the unmanned boat to move.

[0024] Please see Figure 5 The fourth helical gear 6, the auxiliary gear 8, and the fifth helical gear 9 are all installed inside the bracket 1. There are two sets of auxiliary gears 8, which mesh with the fourth helical gear 6 and the fifth helical gear 9 respectively. Since the fourth helical gear 6, the auxiliary gear 8, and the fifth helical gear 9 are all installed inside the bracket 1, when the fourth helical gear 6 rotates, it can drive the fifth helical gear 9 to rotate in the opposite direction through the meshing of the auxiliary gear 8. That is, the rotation direction of the propellers installed at the ends of the first rotating shaft 7 and the second rotating shaft 10 is opposite. In other words, when the propeller pushes the liquid to flow, it avoids generating torque force, thereby improving the stability of the unmanned boat when it is propelled.

[0025] Please see Figure 2 A first helical gear is installed in the middle of the rotating rod 11, and a mounting bracket 13 is installed at the upper end of the bracket 1. A first motor 14 is installed inside the mounting bracket 13. The second gear installed on the output shaft of the first motor 14 meshes with the first helical gear. The rotating rod 11 is installed on the inner side of the arc-shaped toothed plate 2. The first helical gear is installed in the middle of the rotating rod 11, and the second helical gear installed at one end of the first motor 14 meshes with the first helical gear. That is, during the start of the first motor 14, the rotating rod 11 can be driven to rotate. The rotating rod 11 drives the sixth helical gear 12 to rotate. The sixth helical gear 12 simultaneously drives the two sets of third helical gears 5 to rotate, ensuring that the third helical gears 5 maintain synchronicity when rotating.

[0026] Please see Figure 3 The arc-shaped toothed plate 2 and the slide rail 15 are arc-shaped. A second motor 17 is installed in the middle of the diverter plate 16. The gear installed at one end of the output shaft of the second motor 17 meshes with the outside of the arc-shaped toothed plate 2. The arc-shaped toothed plate 2 is sleeved inside the slide rail 15. When the second motor 17 is started, the second motor 17 drives the gear to mesh with the arc-shaped toothed plate 2. That is, the position of the arc-shaped toothed plate 2 inside the slide rail 15 can be adjusted, which can adjust the orientation of the protective cover 4. When the orientation of the protective cover 4 is adjusted, the direction of travel of the unmanned boat can be adjusted. Moreover, the two sets of protective covers 4 rotate synchronously with the rotation of the arc-shaped toothed plate 2 to ensure the stability of the unmanned boat during travel.

[0027] Please see Figure 1 A fixed bracket 18 is fixedly connected to the side of the slide rail 15. The fixed bracket 18 is installed at the rear end of the unmanned vessel. The entire support 1 is submerged in the water. The outside of the diverter plate 16 is conical. The diverter plate 16 is set at the front end of the support 1. The outside of the diverter plate 16 is conical. When the diverter plate 16 moves forward, it effectively reduces water resistance. The diverter plate 16 pushes away impurities in the water. When the equipment is running, it prevents impurities from clogging the inside of the propeller and causing the propeller to jam, thereby improving the safety of the unmanned vessel.

[0028] Please see Figure 1 The first motor 14 and the second motor 17 are both located on the upper end of the fixed frame 18, and wireless monitoring devices are installed inside the first motor 14 and the second motor 17. At the same time, the first motor 14 and the second motor 17 are provided with waterproof layers on the outside. By placing the first motor 14 and the second motor 17 on the upper end of the fixed frame 18, rainwater is reduced from entering the outside of the first motor 14 and the second motor 17. The waterproof layers on the outside of the first motor 14 and the second motor 17 further improve the waterproof effect. At the same time, the wireless monitoring devices on the outside of the first motor 14 and the second motor 17 allow the operator to remotely control the start of the first motor 14 and the second motor 17, thereby controlling the speed and trajectory of the unmanned boat.

[0029] Working principle: During use, the mounting bracket 18 is installed on the outside of the unmanned vessel, and the entire support bracket 1 is submerged in water. The first motor 14 is started, which drives the third helical gear 5 to rotate. The third helical gear 5 drives the fourth helical gear 6 and the first rotating shaft 7 to rotate. With the assistance of the auxiliary gear 8, the fifth helical gear 9 is driven to rotate in the opposite direction. That is, the rotation direction of the second rotating shaft 10 and the first rotating shaft 7 is opposite. Thus, the first rotating shaft 7 and the second rotating shaft 10 rotate in the same direction. During the process of pushing liquid flow, the torsional force is reduced, and the stability of the equipment is improved. During the movement of the equipment, the diverter plate 16 reduces resistance and pushes away impurities in the water, thereby improving the stability during the movement. At the same time, the protective cover 4 is fitted on the outside of the propeller, which protects the outside of the propeller and further improves the protection efficiency. The second motor 17 is started. After the second motor 17 drives the gear to mesh with the arc-shaped toothed plate 2, the direction of the support bracket 1 can be adjusted, thereby realizing the control of the movement direction of the unmanned vessel.
