Description

Technical Field

[0001] The present invention relates to the technical field of propellers, and in particular to a hull power mechanism, a propeller and a hull with a steering function. Background Art

[0002] At present, the principle of the hull propulsion device in the prior art is similar to that of the vertical tail rudder of an airplane. The fluid pushes the rudder surface to generate a driving force to induce steering. When the propeller has no relative flow velocity, the steering function cannot be realized. Alternatively, multiple propellers are distributed on the bottom of the ship to generate thrust. Through the difference in thrust driving force, a torsional moment relative to the center of the hull is generated to achieve steering. However, the response speed is slow, and multiple propulsion propellers need to be installed to increase the complexity. The above two solutions are to fix the output shaft of the servo and the external connecting shaft through the threaded hole and radial spline of the axis. Although the connection is relatively simple, the output shaft of the servo is complex in force. It has to bear axial tensile and compressive stresses while bearing axial torque, which makes it easy for the servo to get stuck and damaged. In order to prevent the servo from getting stuck, the axial positioning accuracy of the servo is required to be extremely high. Summary of the invention

[0036] Reference Figure 1 and Figure 2The embodiment of the present invention provides a hull power mechanism with a steering function, including a driving module 100, the driving module 100 is used to provide power; a steering module 200, the steering module 200 is used to realize the steering function of the hull power mechanism, one end of the steering module 200 is connected to the upper part of the driving module 100, the steering module 200 is provided with a first shell 210, the first shell 210 is provided with a steering gear 211, a steering gear output shaft 213, a steering gear connecting shaft 212 and a top connecting seat 216, the steering gear output shaft 213 is arranged at the upper part of the steering gear 211, the steering gear output shaft 213 is connected to one end of the steering gear connecting shaft 212, the steering gear The other end of the connecting shaft 212 is connected to one end of the top connecting seat 216, wherein a first gap is provided between the steering gear output shaft 213 and the steering gear connecting shaft 212; a connecting module 300, the connecting module 300 is connected to the other end of the top connecting seat 236, and the connecting module 300 is used to connect the hull power mechanism with the hull; a spoiler module 400, the spoiler module 400 is arranged on one side of the driving module 100, and the spoiler module 400 is used to adjust the balance of the hull power mechanism; a diversion module 500, the diversion module 500 is arranged at the bottom of the driving module 100, and the diversion module 500 is used to provide heading stability for the hull power mechanism. According to the technical solution of this embodiment, the steering gear output shaft 213 and the steering gear connecting shaft 212 are connected only by splines as the transmission of torque, thereby avoiding the axial force of the steering gear 211 and effectively reducing the positioning accuracy requirements of the axial installation.

[0037] Among them, the outer surface of the servo connecting shaft is sequentially sleeved with a first bearing, a second bearing and a retaining spring, the first bearing 2123 and the retaining spring 218 are used to bear the upward force exerted on the steering module 200, and the second bearing 2124 is used to bear the downward force exerted on the steering module 200.

[0038] It should be noted that the servo output shaft 213 and the servo connecting shaft 212 cooperate with each other through a spline-keyway to transmit torque, and the servo output shaft 213 and the servo connecting shaft 212 are not fixed with screws in the axial direction, so that a first gap for slight movement exists between the servo output shaft 213 and the servo connecting shaft 212, thereby avoiding axial force on the servo output shaft 213.

[0039] Specifically, refer to Figure 8 and Fig. 9, a force analysis is performed on the steering gear connecting shaft 212. When the hull power structure is subjected to a first downward external force, the transmission order of the first external force is the drive module 100, the first shell 210, the second bearing 2124, and the steering gear connecting shaft 212, which is balanced with the reaction force transmitted from the hull to the steering gear connecting shaft 212. Therefore, the first external force will not be transmitted to the steering gear; when the hull power structure is subjected to a second upward external force, the transmission order of the second external force is the drive module 100, the first shell 210, the first bearing 2123, the retaining spring 218, and the steering gear connecting shaft 212, which is balanced with the reaction force transmitted from the hull to the steering gear connecting shaft 212. Therefore, the second external force will not be transmitted to the steering gear.

[0040] It should be noted that the servo output shaft 213 and the servo connection shaft 212 in the prior art are mostly connected by screws. Since the precision bearing inside the servo 211 is not provided with axial play, when the servo 211 is subjected to external force on one side of the axial direction, the servo 211 itself will bear the external force, thereby causing the servo 211 to become stuck or damaged. In this embodiment, the spline-keyway cooperation between the servo connection shaft 212 and the servo output shaft 213 is used to transmit torque, thereby preventing the servo output shaft 213 from being subjected to axial force.

[0041] Reference Figure 4 The connection module 300 is provided with a first connection member 310 and a torque transmission device 320, the torque transmission device 320 is connected to the first connection member 310 and the top connection seat 216 respectively, the torque transmission device 320 is provided with a first through hole 321, a second through hole 322, a second connection member 323 and a fourth connection member 324, the top connection seat 216 is provided with a first groove 2161 and a second groove 2162, the steering gear connection shaft 212 is provided with a third groove 2121 and a fourth groove 2122, the second connection member 323 is provided with a first through hole 321, a second through hole 322, a second connection member 323 and a fourth connection member 324, the top connection seat 216 is provided with a first groove 2161 and a second groove 2162, the steering gear connection shaft 212 is provided with a third groove 2121 and a fourth groove 2122, and the second connection member 323 is provided with a first through hole 321, a second through hole 322, a second connection member 323 and a fourth connection member 324. The fourth connecting member 324 passes through the first through hole 321 and is inserted into the first groove 2161. The fourth connecting member 324 passes through the second through hole 322 and is inserted into the second groove 2162. The top connecting seat 216 is provided with a first connecting hole 2163 and a second connecting hole 2164. The first connecting hole 2163 is aligned with the third groove 2121, and the second connecting hole 2164 is aligned with the fourth groove 2122. The first connecting hole and the third groove are connected and fixed by screws, and the second connecting hole 2164 and the fourth groove 2122 are fixed. Among them, a first threaded hole 2125 is also provided between the third groove 2121 and the fourth groove 2122. The first threaded hole 2125 is used to connect and fix the steering gear connecting shaft 212 and the top connecting seat 216 by screws. Furthermore, the inner surfaces of the third groove 2121 and the fourth groove 2122 are also provided with threads, and the precise connection with the screws is achieved by the threads, further improving the connection strength of the connection module.

[0042] Reference Figure 2 The driving module 100 includes a second shell 110, a power control chamber 120 and a driving chamber 130. The power control chamber 120 and the driving chamber 130 are arranged inside the second shell 110. The driving chamber 130 includes a driving motor 131, a driving shaft 132 and a propeller 133. The driving motor 131 is connected to one end of the driving shaft 132, and the other end of the driving shaft 132 is connected to the propeller 133.

[0043] It should be noted that the drive chamber 130 and the power control chamber 120 are arranged inside the second shell 110, forming a compact drive module 100, saving hull space, making the entire power mechanism more compact and efficient, and the drive motor 131 is connected to one end of the drive shaft 132, and the power is transmitted by the rotation of the drive shaft 132. This design enables the power to be efficiently transmitted to the propeller 133, thereby driving the hull forward. The cooperation of the drive motor 131 and the drive shaft 132 can achieve rapid transmission and efficient conversion of power. Since the drive module 100 adopts an electric drive mode, the speed and power of the motor can be easily adjusted by the electronic control system. The various components in the drive module 100 adopt a modular design, which makes it more convenient when maintenance or replacement of components is required. The staff can easily disassemble and replace damaged components, reducing maintenance costs and time.

[0044] Reference Figure 2 A gyroscope 121 and an electronic speed regulator 122 are provided in the power control chamber 120. The gyroscope 121 is used to monitor the operating attitude of the hull power mechanism, and the electronic speed regulator 122 is used to adjust and control the direction and speed of the propeller according to the operating attitude. The navigation attitude and heading stability of the propeller are maintained through the cooperation between the gyroscope, the electronic speed regulator and the steering gear.

[0045] It should be noted that the electronic speed governor 122 is used to cooperate with the steering gear to control the defense line and speed of the propeller. The electronic speed governor 122 outputs voltage in real time according to the hull operation attitude information monitored by the gyroscope 121, so as to achieve precise control of the propeller direction and speed. In addition, since the gyroscope 121 can monitor the operation attitude of the hull in real time, when the hull tilts or rotates, the electronic speed governor 122 can respond quickly and quickly restore the hull to a stable state. In this embodiment, through the combined use of the gyroscope 121 and the electronic speed governor 122, the hull power mechanism can be flexibly adjusted according to navigation needs and environmental changes, further enhancing the maneuverability of the hull, so that the operator can more conveniently control the navigation direction and speed of the hull.

[0046] Reference Figure 6 and Figure 7The spoiler module 400 includes a third shell 410 and a spoiler rear cover 420. The third shell 410 is provided with a first opening 411. The spoiler rear cover 420 is provided with a third through hole 421, a cover plate 422 and a plurality of spoiler blades 423 evenly arranged. The cover plate 422 is provided with a first extension plane 4221 and a second extension plane 4222. The first extension plane 4221 is connected to the second extension plane 4222. One end of the plurality of spoiler blades 423 is connected to the outer surface of the second through hole 421, and the other end of the plurality of spoiler blades 423 is connected to the inner surface of the first extension plane 4221. The outer surface of the first extension plane 4221 is connected to the inner surface of the third shell 500, and the second extension plane 4222 is connected to the third shell 500.

[0047] It should be noted that the third housing 500 is the basic structure of the spoiler module 400, and the spoiler module 400 guides and controls the flow of the fluid by setting the second through hole 421, the cover plate 422 and the plurality of spoiler blades 423. The cover plate 422 is formed by connecting the first extension plane 4221 and the second extension plane 4222, so that the fluid flow path can be formed when the hull power mechanism is working. One end of the plurality of spoiler blades 423 is connected to the outer surface of the second through hole 421, and the other end is connected to the inner surface of the first extension plane 4221. When the fluid passes through the second through hole 421, it will be guided by the spoiler blades 423, and the fluid will generate a vortex at the tail after being accelerated by the propeller 133, and the reaction force will generate a torsion along the opposite direction of the rotation of the propeller 133, and the spoiler blades 423 are used to interfere with the tail vortex, and the wake is disturbed into a straight direction to offset the reverse twist. In this embodiment, the spoiler blades 423 and the spoiler rear cover 420 are designed in an integrated manner, which reduces the production cost, and the overall area of ​​the spoiler blades 423 is larger, which can provide a better anti-twist effect.

[0048] It should be noted that the hull steering function in the prior art is usually driven by the rudder, and the fluid pushes the rudder to generate a driving force to turn the hull, but the hull steering function cannot be achieved when the fluid has no relative flow velocity. Alternatively, the thrust is generated by the transmission distribution of multiple propellers, and the torsional moment relative to the center of the hull is generated by the difference in thrust driving force to achieve steering, but the response speed is slow, and the need to install multiple propulsion propellers makes the structure of the propeller more complicated.

[0049] In this embodiment, the propeller is installed at the bottom of the stern, and the single propeller is directly driven by the servo 211 to change the thrust direction, thereby realizing the steering function of the hull. Since the distance relative to the center of the hull is relatively far, it is easier to generate steering torque, and the thrust direction and size can be controlled at the same time. Therefore, the propeller can improve the speed and accuracy of the hull steering, and reduce the size and complexity of the propeller.

[0050] Reference Figure 2 The driving module 100 is also provided with a fairing 140 and a connecting wire 150. A fourth through hole 141 is provided in the middle of the fairing 140. The cross-sectional area of ​​the fairing 140 gradually decreases from one end of the fairing 140 toward one end of the fourth through hole 141. The connecting wire 150 passes through the fourth through hole 141 and is connected to the driving module 100.

[0051] It should be noted that the fairing 140 can effectively reduce the turbulence and resistance of the fluid when it passes through, thereby improving the efficiency of the hull power mechanism and reducing energy consumption, thereby increasing the sailing speed and endurance of the hull. By ensuring that the fluid flows to the drive module 100 in a more stable and controllable manner, the overall stability of the hull power mechanism is improved.

[0052] The driving module 100 is sealed with sealing rings at the front and rear, the output shaft of the driving module 100 is sealed with an oil seal, the driving module 100 and the steering module 200 are sealed with sealing rings, and the steering gear connecting shaft 212 of the steering module 200 is sealed with a sealing ring and an oil seal.

[0053] It should be noted that the two methods of rubber ring sealing and oil seal sealing can effectively prevent pollutants such as moisture and dust from entering the interior of the drive module 100, ensuring that the hull power mechanism can operate stably underwater; the gyroscope 124 and the electronic speed regulator 125 in the power control chamber 120 are sealed with glue, which can improve the waterproof and dustproof performance of the gyroscope 124 and the electronic speed regulator 125, and ensure the accuracy and stability of the gyroscope 124 and the electronic speed regulator 125 when working. In addition, the glue sealing can also play a role in shock absorption and fixing, further improving the stability and reliability of the hull power mechanism. In this embodiment, by setting a variety of sealing methods, it is avoided that a module in the hull power mechanism fails and causes interference and influence on the remaining modules, thereby further enhancing the overall reliability of the hull power mechanism.

[0054] Reference Figure 2 and 3 The outside of the servo connecting shaft 212 is sequentially sleeved with a first bearing 2123 and a second bearing 2124 from top to bottom, the first housing 210 is provided with a servo mounting position 217, the servo 211 is provided with a first limiting protrusion 2111 and a second limiting protrusion 2112, the first limiting protrusion 2111 and the second limiting protrusion 2112 are both placed in the servo mounting position 217 and connected to the first housing 210.

[0055] It should be noted that the first bearing 2123 and the second bearing 2124 are used to bear the axial force acting on the steering module 200. When the steering module 200 is subjected to the axial force, the first bearing 2123 and the second bearing 2124 will bear the force in order from top to bottom, and disperse and transmit the axial force. Avoid the axial force from being directly transmitted to the steering gear 211, thereby ensuring the smooth operation and long-term stability of the steering module 200. Furthermore, the design of the steering gear mounting position 217, the first limiting protrusion 2111 and the second limiting protrusion 2112 ensures that the steering gear can be accurately installed in place, avoids the performance problems caused by inaccurate installation position, and further improves the operation efficiency and accuracy of the steering gear.

[0057] In a third aspect, this embodiment provides a hull, comprising a hull power mechanism as described in the embodiment of the first aspect above.
