Description

[0004] Existing solutions, such as patented technology CN109018283A, involve a ship propeller with blades directly mounted on the propeller. However, since the blades and propeller blades rotate synchronously, it can only perform radial cutting in a single direction, resulting in low efficiency in getting out of trouble. Summary of the Invention

The transmission shaft is rotatably connected to the adjusting frame through the second motor. The mounting frame and the adjusting frame are rotatably connected to the transmission shaft through the fixed shaft.

[0009] The device also includes a cutting mechanism. A propeller is located at one end of the inside of the thruster. A toothed ring is fitted onto the outer surface of the thruster, and both the inner and outer surfaces of the toothed ring have locking teeth. A first motor is fixedly mounted on one side of the outer surface of the thruster. A transmission gear is fixedly mounted on one end of the output shaft of the first motor. A storage groove is formed inside the inner ring, and four sets of blades are placed in the storage groove. One end of each blade is integrally connected to a connecting block. The blade is rotatably connected to the inner ring via the connecting block. Each blade is a four-sided pyramidal blade with a cross-shaped cross section, and the end of the blade is connected to the connecting block via a hinge. The hinge rotates in a direction that allows the blade to tilt and swing relative to the circular plane of the toothed ring. Magnetic blocks are embedded in both the blades and the propeller blades.

[0010] Furthermore, side shafts are fixedly installed on both sides of the bottom end of the mounting bracket, and through grooves matching the side shafts are opened on both sides of the top end of the adjusting bracket.

[0011] Furthermore, a limiting mechanism is provided inside the connecting rod on the other side. The limiting mechanism includes an inner rod inside the connecting rod and a chuck on the other side of the adjusting frame. One end of the inner rod is fixedly connected to the chuck.

[0012] Furthermore, a stop block is fixedly installed at the other end of the inner rod, the stop block is slidably connected to the connecting rod, a spring is sleeved on the outer surface of the inner rod on one side of the stop block, an electromagnet is fixedly installed at one end of the inner rod, the electromagnet is a ring structure and is sleeved on the outer surface of the inner rod, and one end of the spring is in contact with the electromagnet.

[0013] Furthermore, the outer surface of the chuck is provided with a plurality of limiting holes arranged in a ring. A limiting rod is inserted into the inside of the limiting holes, and one end of the limiting rod is fixedly connected to the outer surface of the adjusting frame.

[0014] Furthermore, a propeller is provided at one end of the inside of the thruster, and a toothed ring is fitted on the outer surface of the thruster.

[0015] Furthermore, an inner ring is fixedly installed on the inner wall of the thruster inside the propeller, and the position of the inner ring inside the thruster corresponds to the position of the gear ring.

[0016] Furthermore, the inner ring has a storage groove inside, and four sets of blades are installed in the storage groove. The blades are arc-shaped.

[0017] The technical effects and advantages of this invention are as follows:

[0018] 1. The present invention adjusts the position of the propeller by setting an adjustment mechanism and a lifting mechanism. The lifting mechanism controls the up and down adjustment of the propeller, and the adjustment mechanism can drive the propeller to rotate along the installation mechanism for adjustment, so as to easily adjust the propeller to a suitable position and propel the ship in accordance with the water flow, thereby achieving a certain energy-saving effect and enhancing the applicability of the propeller.

[0019] 2. This invention features retractable blades. When aquatic plants become entangled inside the propeller, the blades can be unfolded and placed close to the propeller blades. Driven by the propeller blades, the blades cut the entangled aquatic plants, detaching them from the propeller and reducing propeller resistance, thus avoiding resource waste. After cleaning, the blades are retracted. Unfolding the blades requires starting the first motor on the outer surface of the propeller. The first motor drives the transmission gear to rotate, which in turn drives the gear ring to rotate. The teeth on the inner side of the gear ring mesh with the connecting block at one end of the blade. As the gear ring rotates, it drives the connecting block to rotate as well, thus unfolding the blades from inside the inner ring. After use, the motor drives the gear ring to retract the blades. The blades are arc-shaped, making it easy to store multiple sets of blades inside the inner ring and reducing wear on the blades.

[0020] 3. The present invention uses a cross-shaped, quadrangular pyramidal blade design to enable comprehensive cutting in multiple radial and axial directions. At the same time, the hinged connection and swing design of the spiral blades and the magnetic block inside the blade body enables cutting with multiple dimensions, forces and amplitudes, which greatly improves the efficiency of getting out of trouble.

[0031] The technical solutions of 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.

[0032] according to Figure 1-6 The illustrated marine propulsion energy-saving device includes a thruster 1, the top of which is provided with an adjustment mechanism for adjusting the position of the thruster 1, and the top of the adjustment mechanism is provided with an installation mechanism.

[0033] The adjustment mechanism includes an adjustment frame 2 and an inner frame 24 disposed inside the adjustment frame 2. The outer surface of the pusher 1 at the bottom end of the inner frame 24 is integrally connected. An installation groove is opened inside the adjustment frame 2, and a cylinder 25 is fixedly installed in the installation groove. The output shaft of the cylinder 25 is fixedly connected to the inner wall of the mounting frame 3. The adjustment frame 2 and the inner frame 24 are slidably connected. When adjusting the position of the pusher 1, the cylinder 25 inside the inner frame 24 is first activated to push the adjustment frame 2, thereby driving the inner frame 24 to push downward, pushing the pusher 1 downward, and raising and lowering the pusher 1.

[0034] The device also includes a cutting mechanism. A propeller 11 is installed at one end of the inside of the propeller 1. A toothed ring 12 is fitted onto the outer surface of the propeller 1, and both the inner and outer surfaces of the toothed ring 12 have locking teeth. A first motor 13 is fixedly installed on one side of the outer surface of the propeller 1. A transmission gear 15 is fixedly installed at one end of the output shaft of the first motor 13. A storage groove is opened inside the inner ring 14, and four sets of blades 16 are installed in the storage groove. One end of each blade 16 is integrally connected to a connecting block 17. The blade 16 is rotatably connected to the inner ring 14 through the connecting block 17. The blade 16 is a four-sided pyramidal blade with a cross-shaped cross section, and the end of the blade 16 is connected to the connecting block 17 through a hinge. The rotation direction of the hinge allows the blade to tilt and swing relative to the circular plane of the toothed ring 12. Magnetic blocks are embedded in both the blades 16 and the propeller 11 blades. This design allows for cutting and swinging in multiple directions and positions when removing aquatic plants and other debris, greatly improving the efficiency of aquatic plant cutting.

[0035] The mounting mechanism includes a mounting frame 3, with a groove at the bottom and a fixed shaft 31 inside the groove. A transmission shaft 22 is mounted at the top of the adjusting frame 2, with connecting rods 28 fixedly mounted at both ends. The fixed shaft 31 meshes with the transmission shaft 22. A second motor 21 is fixedly mounted on one side of the adjusting frame 2, with one end of the output shaft of the second motor 21 fixedly connected to one of the connecting rods 28. The transmission shaft 22 is rotatably connected to the adjusting frame 2 via the second motor 21. The mounting frame 3 and the adjusting frame 2 are rotatably connected to the transmission shaft 22 via the fixed shaft 31. Side shafts 32 are fixedly mounted on both sides of the bottom of the mounting frame 3. Through slots 23 matching the side shafts 32 are provided on both sides of the top of the adjusting frame 2. The second motor 21 drives the transmission shaft 22 to rotate, and the transmission shaft 22 meshes with the fixed shaft 31, thereby causing the adjusting frame 2 to rotate along the mounting frame 3. During rotation, the connecting rods 28 drive the chuck 26 to rotate as well.

[0036] Furthermore, a limiting mechanism is provided inside the connecting rod 28 on the other side. This limiting mechanism includes an inner rod 281 inside the connecting rod 28 and a chuck 26 on the other side of the adjusting frame 2. One end of the inner rod 281 is fixedly connected to the chuck 26, and a stop 282 is fixedly installed at the other end of the inner rod 281. The stop 282 is slidably connected to the connecting rod 28. A spring 283 is sleeved on the outer surface of the inner rod 281 on one side of the stop 282. An electromagnet 284 is fixedly installed at one end of the inner side of the connecting rod 28. The electromagnet 284 is a ring structure and is sleeved on the outer surface of the inner rod 281. One end of the spring 283 is in contact with the electromagnet 284. When the electromagnet 284 at one end of the connecting rod 28 is activated, the stop block is attracted by the magnetic force of the electromagnet 284, which drives the inner rod 281 to move outward and pushes the chuck 26 outward until the limiting rod 27 disengages from the limiting hole 261 of the chuck 26, thus releasing the limitation on the chuck 26.

[0037] Furthermore, the outer surface of the chuck 26 is provided with a plurality of limiting holes 261 arranged in a ring. A limiting rod 27 is inserted into the inside of the limiting hole 261. One end of the limiting rod 27 is fixedly connected to the outer surface of the adjusting frame 2. After the adjusting frame 2 has adjusted the position of the pusher 1, the electromagnet 284 is turned off, and the spring 283 will pull the stop block 282 back inward, resetting the chuck 26 and inserting the limiting rod 27 into the corresponding limiting hole 261 to limit and fix the adjusting frame 2.

[0038] The specific implementation method is as follows: The position of the thruster is adjusted by the set adjustment mechanism and lifting mechanism. The lifting mechanism controls the up and down adjustment of the thruster, and the adjustment mechanism can drive the thruster to rotate and adjust along the mounting mechanism, so as to adjust the thruster 1 to a suitable position to propel the ship in accordance with the water flow, thereby achieving a certain energy-saving effect and enhancing the applicability of the thruster 1. When adjusting the position of the thruster 1, the cylinder 25 inside the inner frame 24 is first activated to push the adjustment frame 2, thereby driving the inner frame 24 to push downward, pushing the thruster 1 downward, and lifting the thruster 1 up and down. Then, the electromagnet 284 at one end of the connecting rod 28 is activated. The stop block is attracted by the magnetic force of the electromagnet 284, driving the inner rod 281 outward. Move the chuck 26 outward until the limiting rod 27 disengages from the limiting hole 261 of the chuck 26, releasing the limiting of the chuck 26. Then, start the second motor 21 on one side of the adjusting frame 2. The second motor 21 drives the transmission shaft 22 to rotate. The transmission shaft 22 meshes with the fixed shaft 31, thereby driving the adjusting frame 2 to rotate along the mounting frame 3. During the rotation, the connecting rod 28 will drive the chuck 26 to rotate together. After the position of the pusher 1 is adjusted by the adjusting frame 2, turn off the electromagnet 284. The spring 283 will pull the stop block 282 inward, resetting the chuck 26 and allowing the limiting rod 27 to insert into the corresponding limiting hole 261, limiting and fixing the adjusting frame 2, increasing the stability of the pusher 1.

[0039] according to Figure 7-9 The above describes a marine propulsion energy-saving device. One end of the propeller 1 is equipped with a propeller 11, and a toothed ring 12 is fitted on the outer surface of the propeller 1. The toothed ring 12 is rotatably connected to the propeller 1, and both the inner and outer surfaces of the toothed ring 12 are provided with locking teeth.

[0040] Furthermore, a first motor 13 is fixedly installed on one side of the outer surface of the propeller 1. A transmission gear 15 is fixedly installed at one end of the output shaft of the first motor 13. The transmission gear 15 is meshed with the teeth on the outer surface of the gear ring 12. When the first motor 13 on the outer surface of the propeller 11 is started, the transmission gear 15 is driven to rotate through the first motor 13, and the transmission gear 15 drives the gear ring 12 to rotate.

[0041] Furthermore, an inner ring 14 is fixedly installed on the inner wall of the propeller 1 inside the propeller 11, and the inner ring 14 is positioned inside the propeller 1 in a position corresponding to the position of the toothed ring 12. The teeth on the inner side of the toothed ring 12 mesh with the connecting block 17 at one end of the blade 16. During the rotation of the toothed ring 12, the connecting block 17 is driven to rotate together, thereby unfolding the blade 16 from inside the inner ring 14.

[0042] Furthermore, the inner ring 14 has a storage groove inside, and four sets of blades 16 are provided in the storage groove. The blades 16 are arc-shaped, which makes it convenient to store multiple sets of blades 16 inside the inner ring 14.

[0043] Furthermore, one end of the blade 16 is integrally connected to the connecting block 17, and the blade 16 is rotatably connected to the inner ring 14 through the connecting block 17. The connecting block 17 is engaged with the retaining teeth on the inner side of the toothed ring 12.

[0044] The specific implementation method is as follows: When aquatic plants become entangled inside the propeller 11, the blade 16 can be unfolded. After unfolding, the blade 16 is close to the propeller blades, and under the drive of the propeller blades, it cuts the entangled aquatic plants, causing them to detach from the propeller 11, reducing the resistance of the propeller 11 during use and avoiding waste of resources. After cleaning, the blade 16 is retracted. When unfolding the blade 16, the first motor 13 on the outer surface of the propeller 11 needs to be started. The first motor 13 drives the transmission gear 15 to rotate, and the transmission gear 15 drives the gear ring 12 to rotate. The teeth on the inner side of the gear ring 12 mesh with the connecting block 17 at one end of the blade 16. During the rotation of the gear ring 12, the connecting block 17 rotates together, thereby unfolding the blade 16 from inside the inner ring 14. After use, the first motor 13 drives the gear ring 12 to retract the blade 16. The blade 16 is arc-shaped, which makes it easy to store multiple sets of blades 16 inside the inner ring 14, reducing wear on the blade 16.

[0045] Refer to the instruction manual appendix Figure 1-6 When adjusting the position of the pusher 1, first start the cylinder 25 inside the inner frame 24 to push the adjusting frame 2, thereby driving the inner frame 24 to push down and push the pusher 1 down, so as to lift and lower the pusher 1. Then start the second motor 21 on one side of the adjusting frame 2, and drive the transmission shaft 22 to rotate through the second motor 21. The transmission shaft 22 is meshed with the fixed shaft 31, thereby driving the adjusting frame 2 to rotate along the mounting frame 3. During the rotation, the connecting rod 28 will drive the chuck 26 to rotate together. After the position of the pusher 1 is adjusted by the adjusting frame 2, the electromagnet 284 is turned off, and the spring 283 will pull the stop block 282 inward, and the chuck 26 will be reset, so that the limiting rod 27 is inserted into the corresponding limiting hole 261 to limit and fix the adjusting frame 2.

[0046] Refer to the instruction manual appendix Figure 7-9When unfolding the blade 16, the first motor 13 on the outer surface of the propeller 11 needs to be started. The first motor 13 drives the transmission gear 15 to rotate, which in turn drives the gear ring 12 to rotate. The teeth on the inner side of the gear ring 12 mesh with the connecting block 17 at one end of the blade 16. As the gear ring 12 rotates, it drives the connecting block 17 to rotate as well, thereby unfolding the blade 16 from inside the inner ring 14. After use, the first motor 13 drives the gear ring 12 to retract the blade 16. The blade 16 is arc-shaped, which makes it easy to store multiple sets of blades 16 inside the inner ring 14, reducing wear on the blade 16. After the inner ring 14 unfolds, the propeller blades drive the aquatic plants to rotate during the cutting process. When the aquatic plants come into contact with the four-sided pyramidal blades, they are directly and passively cut. Under the magnetic attraction of the blades and the magnetic blocks inside the propeller, the blades make a hinged swinging motion, thereby actively cutting the aquatic plants. Since the magnetic blocks on the propeller are constantly rotating, the four blades can swing in different amplitudes in a cycle, which can also exert a partial drag force on the aquatic plants, making it easier to cut and crush them. In addition, the cross-shaped four-sided pyramidal blade design enables comprehensive cutting in multiple directions, including radial and axial directions, improving the efficiency of getting out of trouble.
