Description

Technical Field

[0001] This utility model relates to the field of new energy electric propulsion technology, and in particular to a new energy electric propulsion for light ships. Background Technology

[0002] With increasing environmental awareness and a pursuit of energy efficiency, light vessels are increasingly adopting new energy electric propulsion systems. These systems use electric motors to drive propellers, providing power to the vessel. They offer advantages such as low noise, zero pollution, and flexible operation, and are widely used in inland waterway transportation, small cruise ships, and offshore vessels.

[0003] In actual ship navigation, the waterway environment is often quite complex. Inland waterways may contain a large amount of floating debris, such as branches, garbage, and aquatic plants. When a ship approaches these areas, the propeller can easily collide with these underwater objects, causing deformation, breakage, or wear of the propeller blades. Once the propeller is damaged, its geometry changes, leading to a sharp decrease in propulsion efficiency. Furthermore, it disrupts the propeller's dynamic balance, not only reducing propulsion but also causing ship vibration, further affecting the ship's maneuverability and comfort. Currently, some ships use simple physical protective devices, such as installing metal grilles around the propeller. However, while these grilles prevent larger floating objects from escaping, they are easily entangled by aquatic plants and garbage, which in turn affects the normal operation of the propeller. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a new energy electric propulsion device for light ships, which can solve the problem that the propeller is easily affected by objects in the water, affecting its performance and causing damage.

[0006] To achieve the above objectives, this utility model proposes a new energy electric propulsion system for light vessels, comprising a waterjet propulsion unit, a power motor, and a drive shaft. The waterjet propulsion unit has a mounting base at its bottom, and an annular protective net is installed inside the mounting base. The waterjet propulsion unit is mounted on the hull via the mounting base. A protective cover is installed at the bottom of the mounting base, and a connection interface is provided on the mounting base. An internal slot is provided inside the protective cover, corresponding to the space of the connection interface. The annular protective net is rotatably connected to the inner wall of the internal slot. A rear water inlet corresponding to the space of the internal slot is provided on one side of the protective cover, and an inclined drainage surface is provided at the bottom of the protective cover, positioned in the forward direction of the mounting base.

[0007] This utility model discloses a new energy electric propulsion system for light-duty vessels. Through the combined use of a rear-mounted water inlet and a ring-shaped protective net, it prevents debris from entering the internal tank and waterjet propulsion unit, thereby improving the protection of the propeller inside the waterjet propulsion unit. Simultaneously, it reduces the probability of debris in the water coming into contact with the ring-shaped protective net, further reducing the problem of the net becoming clogged. This facilitates a stable water supply and solves the problem of propellers easily colliding with underwater objects, causing deformation, breakage, or wear of the propeller blades. Once the propeller is damaged, its geometry changes, leading to a sharp drop in propulsion efficiency and disrupting the propeller's dynamic balance. This not only reduces propulsion but also causes ship vibration, further affecting the ship's maneuverability and comfort.

[0008] In addition, the new energy electric propulsion device for light ships proposed above according to this utility model may also have the following additional technical features:

[0009] Specifically, two cleaning ramps are installed on the inner wall of the content tank, and both cleaning ramps correspond to the position of the rear water inlet. Both cleaning ramps are slidably connected to the side wall of the annular protective net.

[0010] Specifically, a rotating rod is provided inside the annular protective net, the rotating rod is rotatably connected to the inner wall of the inner groove, and a cross connecting frame is installed on the side wall of the rotating rod, the cross connecting frame is installed on the inner wall of the annular protective net.

[0011] Specifically, a number of driven blades are installed on the side wall of the rotating rod, and all of the driven blades are located inside the interface space. The driven blades do not contact the water jet propulsion device.

[0012] Specifically, a connecting cover is installed at one end of the water jet propulsion unit, the connecting cover is sleeved on the side wall of the drive shaft, a water storage cover is installed at the bottom end of the connecting cover, a water leakage sensor is installed on one side of the connecting cover, and the water storage cover is connected to the internal space of the water leakage sensor.

Detailed Implementation

[0021] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Rather, the embodiments of this utility model include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0022] The following description, in conjunction with the accompanying drawings, describes a new energy electric propulsion system for a light-duty ship according to an embodiment of the present invention.

[0023] like Figures 1-4 As shown in the figure, a new energy electric propulsion device for a light ship according to an embodiment of the present utility model may include a water jet propulsion device 1, a power motor 11 and a drive shaft 12. The bottom of the water jet propulsion device 1 is equipped with a mounting base 2, and a ring-shaped protective net 3 is provided inside the mounting base 2.

[0024] The water jet propulsion unit 1 is mounted on the hull via a mounting base 2. A protective cover 21 is installed at the bottom of the mounting base 2. An interface 22 is provided on the mounting base 2. A content slot 23 is provided inside the protective cover 21. The content slot 23 corresponds spatially to the interface 22.

[0025] It should be noted that the content slot 23 described in this embodiment is connected to the internal space of the water jet propulsion unit 1 through the interface 22.

[0026] The ring-shaped protective net 3 is rotatably connected to the inner wall of the contents 23, and the protective cover 21 has a rear water inlet 231 on one side corresponding to the space of the contents 23.

[0027] It should be noted that the rear water inlet 231 described in this embodiment corresponds to the position of the annular protective net 3.

[0028] The protective cover 21 has an inclined drainage surface 211 at the bottom, and the inclined drainage surface 211 is in the forward direction of the mounting base 2.

[0029] It should be noted that the rear water inlet 231 and the inclined drainage surface 211 described in this embodiment are in opposite positions on the protective cover 21.

[0030] Specifically, to address the issue of propellers being easily affected by objects in the water, thus impacting performance and causing damage, the waterjet propeller 1 is connected to a light vessel via a mounting base 2. The power motor 11 is powered by a new energy battery, promoting energy conservation and emission reduction, making it more environmentally friendly and quieter. The power motor 11 drives the propeller inside the waterjet propeller 1 via a drive shaft 12, enabling the device to propel the vessel in the water. The waterjet propeller 1 draws water from the interface 22, the inner tank 23, and the rear water inlet 231, then uses the propeller to propel the vessel. The rear water inlet 231 is located behind the protective cover 21, allowing water to be supplied to the inner tank 23 as the vessel propels the waterjet propeller 1 and the protective cover 21 forward, facilitating vessel propulsion. The protective cover 21 shields the vessel from debris in the water during movement, preventing debris from entering. The water jet enters the internal tank 23 and the water jet propeller 1, thereby improving the protection of the propeller inside the water jet propeller 1. The annular protective net 3 is designed to rotate. When rotating, the annular protective net 3 can align itself with the rear water inlet 231 at different positions, thereby reducing the problem of easy blockage in a single area of ​​the annular protective net 3. In addition, the exposed surface of the annular protective net 3 is also located at the rear of the direction of travel, reducing the probability of debris in the water coming into contact with the annular protective net 3, further reducing the problem of blockage of the annular protective net 3, which is conducive to a stable water supply. This solves the problem that the propeller is prone to colliding with underwater objects, causing deformation, breakage or wear of the propeller blades. Once the propeller is damaged, its geometry changes, which leads to a sharp drop in propulsion efficiency and disrupts the dynamic balance of the propeller. This not only reduces propulsion but also causes ship vibration, further affecting the ship's maneuverability and comfort.

[0031] In one embodiment of this utility model, such as Figures 1-4 As shown, two cleaning ramps 24 are installed on the inner wall of the content tank 23. Both cleaning ramps 24 correspond to the position of the rear water inlet 231, and both cleaning ramps 24 are slidably connected to the side wall of the annular protective net 3.

[0032] It should be noted that the two cleaning ramps 24 described in this embodiment are symmetrically distributed.

[0033] Specifically, when the annular protective net 3 rotates in the inner tank 23, the rear water inlet 231 contacts the side wall of the annular protective net 3 through two cleaning inclined blocks 24, so that the annular protective net 3 can scrape and clean the intercepted debris during rotation, preventing the annular protective net 3 from being blocked, which is conducive to the stable use of the device.

[0034] In one embodiment of this utility model, such as Figures 1-4 As shown, a rotating rod 31 is provided inside the annular protective net 3. The rotating rod 31 is rotatably connected to the inner wall of the inner groove 23. A cross connecting frame 32 is installed on the side wall of the rotating rod 31. The cross connecting frame 32 is installed on the inner wall of the annular protective net 3.

[0035] It should be noted that the rotating rod 31 described in this embodiment is located at the center of the internal space of the annular protective net 3.

[0036] Specifically, the protective cover 21 supports the rotating rod 31, and the rotating rod 31 supports and rotates the annular protective net 3 through the cross connecting frame 32, so that the annular protective net 3 can maintain stable rotation in the inner groove 23 and prevent the annular protective net 3 from tilting or shifting.

[0037] In one embodiment of this utility model, such as Figures 1-4 As shown, several driven blades 33 are installed on the side wall of the rotating rod 31. All the driven blades 33 are located in the internal space of the interface 22. The driven blades 33 do not contact the water jet propulsion unit 1.

[0038] It should be noted that the driven blade 33 described in this embodiment is located in the area above the cross connector 32.

[0039] Specifically, the water source enters the inner tank 23 through the rear water inlet 231 and continues to flow upward. The water source passes through the docking port 22 and enters the water jet propulsion 1. At the same time, the water flow pushes several driven blades 33, so that the driven blades 33 can drive the rotating rod 31 to rotate, which in turn drives the cross connecting frame 32 and the ring protective net 3 to rotate, thus completing the automatic cleaning of the ring protective net 3.

[0040] In one embodiment of this utility model, such as Figures 1-4 As shown, a connecting cover 4 is installed at one end of the water jet propulsion 1. The connecting cover 4 is sleeved on the side wall of the drive shaft 12. A water storage cover 41 is installed at the bottom of the connecting cover 4. A water leakage sensor 42 is installed on one side of the connecting cover 4. The water storage cover 41 and the water leakage sensor 42 are connected in the internal space.

[0041] It should be noted that the connecting cover 4 described in this embodiment is located at the connection point on the outside of the water jet propulsion unit 1 and the drive shaft 12.

[0042] Specifically, the water jet propulsion unit 1 supports the connecting cover 4, and the connecting cover 4 externally wraps the connection between the water jet propulsion unit 1 and the drive shaft 12. When the sealing between the water jet propulsion unit 1 and the drive shaft 12 deteriorates after long-term use, water leakage will occur at the connection between the water jet propulsion unit 1 and the drive shaft 12. At this time, the connecting cover 4 collects the leaking water in advance. The connecting cover 4 senses the water source through a leakage sensor 42 on one side. When the leakage sensor 42 senses a water leak, it transmits a wireless signal to the ship's PLC control system, so that the staff can be informed of the situation in time and carry out maintenance to prevent serious water leakage from damaging the power motor 11 and the battery. The connecting cover 4 diverts the water source into the water storage cover 41, and uses the water storage cover 41 to improve the storage capacity of the leaking water source, thus buying time for maintenance.

[0043] In summary, the new energy electric propulsion system for light-duty ships according to this utility model embodiment, when the ship is in use, controls the power motor 11 to drive the drive shaft 12 to rotate, the drive shaft 12 drives the propeller inside the water jet propulsion unit 1 to rotate, the propeller drives the water source, and uses the reaction force to propel the ship forward. The inclined guide surface 211 guides the water source and reduces the resistance to movement. The rear water inlet 231 is located behind the protective cover 21. The water source enters the inner tank 23 through the rear water inlet 231 and continues to flow upward. The water source passes through the interface 22 and enters the water jet propulsion unit 1. At the same time, the water flow pushes several driven blades 33, so that the driven blades 33 can drive the rotating rod 31 to rotate, and then the rotating rod 31 can drive the cross connecting frame 32 and the ring protective net 3 to rotate, completing the automatic cleaning work of the cleaning inclined block 24 on the ring protective net 3, reducing the probability of debris in the water contacting the ring protective net 3, further reducing the problem of the ring protective net 3 being blocked, and facilitating a stable water supply.

[0044] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
