Description

Technical Field

[0001] This invention relates to a propulsion device for boats, and more particularly to a semi-submerged propeller mechanism and a boat having the same. Background Technology

[0002] A semi-submerged propeller is a type of propeller in which part of the blades are exposed above the water while the propeller is in motion at high speed. This type of propeller is commonly used in speedboats and small fishing boats.

[0003] Existing semi-submerged propellers only adjust the propeller's entry and exit from the water in an arc, or only adjust the propeller's height in the vertical direction. These existing semi-submerged propellers require manual adjustment of the propeller's height after changes in the boat's load or due to wind and waves, which is very troublesome. In addition, the existing semi-submerged propellers have limited adjustment and drive methods, which limits their use. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a semi-submerged propeller mechanism that can adapt to the navigation conditions of boats and increases the adjustment methods of the propeller for easy adjustment.

[0005] The present invention also proposes a boat having the above-mentioned semi-submerged propeller mechanism.

[0006] According to a first aspect of the present invention, a semi-submerged propeller mechanism includes a mounting body, a deflector block, a lifting frame, a float, a drive shaft, a connecting shaft, a buoyancy adjustment unit, and a tilt adjustment unit. The deflector block is rotatably connected to the mounting body, the lifting frame is slidably connected to the deflector block vertically, the float is connected to the lower end of the lifting frame, and the float provides buoyancy to the lifting frame. The drive shaft is rotatably connected to the lifting frame about its own axial direction, one end of the drive shaft is connected to a propeller, one end of the connecting shaft is connected to the other end of the drive shaft via a first universal joint, and the other end of the connecting shaft is connected to a rotating power component via a second universal joint. The buoyancy adjustment unit is connected to the float and is used to inflate or depress the float. The tilt adjustment unit is disposed on the mounting body and is connected to the deflector block, and is used to adjust the rotation angle of the deflector block.

[0007] This semi-submerged propeller mechanism has at least the following beneficial effects: By using a pontoon, the lifting frame is raised and lowered using buoyancy. Since the lifting frame is connected to the drive shaft and the propeller, the pontoon can drive the propeller to rise and fall. The deflection block connects the lifting frame; when the deflection block deflects, the lifting frame can deflect the propeller along with it. This allows for the raising, lowering, and deflecting of the propeller, enabling the propeller to have various configurations to adapt to different navigation requirements. The pontoon and buoyancy adjustment unit work together so that initially, the buoyancy of the pontoon is just enough to submerge half of the propeller underwater. When inflating and deflating using the buoyancy adjustment unit, the raising and lowering of the propeller can be adjusted. The tilt adjustment unit, designed to facilitate adjustment of the propeller's pitch angle, combined with the lifting and lowering adjustment of the pontoon, enables multi-mode and multi-method adjustment of the propeller. In the initial state, the lifting frame of this semi-submerged propeller mechanism is vertical, and the propeller is horizontal and half-submerged. It can adaptively adjust its height, meaning that even after changes in the boat's load or the influence of wind and waves, the propeller and lifting frame can automatically adjust their height while remaining half-submerged. This is the most common usage scenario. When speed needs to be adjusted, the tilt adjustment unit is used to adjust the propeller's tilt angle. Because the tilt angle has been changed, the initial balance has been disrupted. Then, the pontoon needs to be inflated or deflated to actively change the buoyancy so that the propeller is half-submerged again, achieving coordinated adjustment and reaching a new balance. This new balance can also adapt to changes in the boat's load or the influence of wind and waves.

[0008] According to some embodiments of the present invention, the float includes a connecting plate and a folding airbag. The connecting plate is connected to the lower end of the lifting frame, and the folding airbag is sealed to the lower end of the connecting plate. The buoyancy adjustment unit is connected to the folding airbag. The float has a simple structure, and the connecting plate facilitates connection to the lifting frame and deployment of the folding airbag.

[0009] According to some embodiments of the present invention, the lower end of the folding airbag is provided with a base plate, and a bottom-touching wheel is connected to the base plate. The height of the bottom-touching wheel is lower than the height of the propeller. The bottom-touching wheel is used to contact the bottom of the water. The base plate facilitates the installation of the bottom-touching wheel. When the bottom-touching wheel faces the sloping bottom, it can push the deflection block to offset, causing the propeller to tilt upward and avoid the propeller touching the bottom.

[0010] According to some embodiments of the present invention, the buoyancy adjustment unit includes an air box and a piston. The air box is disposed on the mounting body, and the piston is slidably connected to the inner cavity of the air box. The piston divides the inner cavity of the air box into an air chamber and a power chamber. The air chamber is connected to the folding airbag through a hose. The piston is connected to the inner wall of the air box by a spring. The spring is housed in the power chamber and is used to drive the piston to a predetermined position. A driving air source is connected to the outside of the power chamber and is used to drive the piston to move. The buoyancy adjustment unit has a simple structure. It uses the spring to maintain the position of the piston, ensuring that the folding airbag is filled with a predetermined amount of gas, maintaining the propeller in a semi-submerged state. At the same time, it can also be reset by the spring when the folding airbag fluctuates.

[0011] According to some embodiments of the present invention, the tilt adjustment unit includes a bracket, a push rod, a drive screw, and a handwheel. The bracket is disposed on the mounting body, the push rod is slidably connected to the bracket, one end of the push rod is configured to push the deflection block, and the other end of the push rod is threadedly connected to the drive screw. One end of the drive screw is rotatably connected to the bracket, and the other end of the drive screw is connected to the handwheel. The tilt adjustment unit utilizes the push rod and the drive screw to achieve stepless adjustment of the deflection block, facilitating active driving of the deflection block to deflect.

[0012] According to some embodiments of the present invention, a connecting arm is hinged to the deflection block, and the connecting arm is detachably hinged to one end of the push rod. The connecting arm provides a higher degree of freedom in the connection between the deflection block and the push rod, making it easier for the deflection block to rotate.

[0013] According to some embodiments of the present invention, a locking member is further included, which is disposed on the mounting body and is used to lock the deflection block.

[0014] According to some embodiments of the present invention, the deflection block is connected to a rotating shaft, the rotating shaft is rotatably connected to the mounting body, the locking member includes a brake pad, the brake pad is covered on the rotating shaft, the brake pad is driven by a braking power member, the braking power member drives the brake pad to brake the rotating shaft, the locking member has a simple structure and is convenient for locking the deflection block to position the angle of the propeller.

[0015] According to some embodiments of the present invention, the upper end of the lifting frame is provided with a receiving groove for receiving a counterweight.

[0016] According to a second aspect of the present invention, a boat includes a hull and the aforementioned semi-submerged propeller mechanism, wherein the mounting body is disposed on the hull.

[0017] It has at least the following beneficial effects: This vessel has all the beneficial effects brought about by the above-mentioned semi-submerged propeller mechanism, which will not be repeated here.

[0018] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0034] In the description of this invention, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0035] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0036] Reference Figures 1 to 5 This invention discloses a semi-submerged propeller mechanism, comprising a mounting body 100, a deflector block 200, a lifting frame 300, a pontoon 400, a drive shaft 500, a connecting shaft 600, a buoyancy adjustment unit 700, and an tilt adjustment unit 800. The deflector block 200 is rotatably connected to the mounting body 100; the lifting frame 300 is slidably connected to the deflector block 200 along a vertical direction; the pontoon 400 is connected to the lower end of the lifting frame 300 and is used to provide buoyancy to the lifting frame 300; the drive shaft 500 is rotatably connected to the lifting frame 300 about its own axial direction. One end of the drive shaft 500 is connected to the propeller; one end of the connecting shaft 600 is connected to the other end of the drive shaft 500 via the first universal joint 610, and the other end of the connecting shaft 600 is connected to the rotating power component via the second universal joint 620; the buoyancy adjustment unit 700 is connected to the float box 400, and the buoyancy adjustment unit 700 is used to inflate or depress the float box 400; the tilt angle adjustment unit 800 is mounted on the mounting body 100, and the tilt angle adjustment unit 800 is connected to the deflection block 200, and the tilt angle adjustment unit 800 is used to adjust the tilt angle of the deflection block 200.

[0037] Reference Figure 1One end of the connecting shaft 600 is connected to the other end of the drive shaft 500 via the first universal joint 610. The other end of the connecting shaft 600 is connected to the second universal joint 620, which is used to drive the power component. The buoyancy adjustment unit 700 is connected to the float box 400 and is used to inflate or depress the float box 400. The tilt adjustment unit 800 is mounted on the mounting body 100 and is connected to the deflection block 200. The tilt adjustment unit 800 is used to adjust the rotation angle of the deflection block 200. It should be noted that the first universal joint 610, the second universal joint 620, and the connecting shaft 600 are used to achieve universal power transmission, avoiding the loss of power transmission during propeller lifting and deflection. The deflection achieves a small angle of deflection and change, with the deflection angle between -10° and 10°. Therefore, the displacement of the connecting shaft 600 is also only a small displacement. To prevent the universal joint transmission parts from being immersed in water, a waterproof cover can be installed and connected to the lifting frame 300. The waterproof cover seals the first universal joint 610, and the transmission parts that are submerged in water are all equipped with an anti-corrosion layer, such as an electroplated nickel layer or an electroplated chromium layer. Cathodic protection can also be used to protect the transmission parts. In addition, because a waterproof cover is installed, applying grease to the first universal joint 610 will facilitate smooth transmission.

[0038] In addition, the buoyancy adjustment unit 700 can be completely replaced by an air pump, with the motor of the air pump connected to a controller. The controller is a commonly used controller, mainly controlling the start, stop and reverse rotation of the air pump motor. Using this control relationship, the float box 400 can be inflated or inhaled, and the propeller position can be determined by observation to see if it meets the navigation requirements.

[0039] It should be understood that this application uses a float 400 to raise and lower the lifting frame 300 by utilizing buoyancy. Since the lifting frame 300 is connected to the drive shaft 500 and the propeller, the float 400 can drive the propeller to rise and fall. The deflection block 200 connects the lifting frame 300. When the deflection block 200 deflects, the lifting frame 300 can deflect along with the propeller. Thus, the lifting and deflection of the propeller can be realized, allowing the propeller to have multiple shapes to adapt to different navigation requirements. The float 400 and the buoyancy adjustment unit 700 work together so that the buoyancy of the float 400 is just enough to submerge half of the propeller underwater at the beginning. When the buoyancy adjustment unit 700 is used for inflation and deflation, the lifting distance of the propeller can be adjusted. The tilt adjustment unit 800 facilitates the adjustment of the propeller's pitch angle. Combined with the lifting adjustment of the float 400, multiple modes and methods of propeller adjustment can be realized.

[0040] It should be noted that in the initial state, the lifting frame 300 of this semi-submerged propeller mechanism is in a vertical position, and the propeller is in a horizontal position and half submerged. It can adaptively raise and lower, that is, after the load of the boat changes or is affected by wind and waves, the propeller and lifting frame can also automatically raise and lower, and can still be half submerged. This is the most common use scenario. Because the speed needs to be adjusted, the tilt angle adjustment unit is used to adjust the tilt angle of the propeller. Because the tilt angle is changed, the initial balance is broken. Then, the float box 400 needs to be inflated and deflated to actively change the buoyancy so that the propeller is submerged halfway again, achieving coordinated adjustment and reaching a new balance. This new balance can also adapt to changes in the load of the boat or the influence of wind and waves.

[0041] Understandably, since the lifting frame 300 is connected to the drive shaft 500 and the propeller, the thrust generated by the propeller can be transmitted to the lifting frame 300, which in turn can transmit the force to the deflector block 200, which in turn can transmit the force to the rotating shaft 220, which is connected to the mounting body 100. Therefore, the entire mounting body 100 can transmit the force to the boat.

[0042] In some embodiments, the float 400 includes a connecting plate 410 and a folding airbag 420. The connecting plate 410 is connected to the lower end of the lifting frame 300, and the folding airbag 420 is sealed to the lower end of the connecting plate 410. The buoyancy adjustment unit 700 is connected to the folding airbag 420. The float 400 has a simple structure. The connecting plate 410 facilitates connection to the lifting frame 300 and also facilitates the deployment of the folding airbag 420. It should be noted that the folding airbag 420 is an airbag that can be folded vertically, and the exterior of the folding airbag 420 is coated with an anti-corrosion layer.

[0043] It should be noted that the lower end of the folding airbag 420 is provided with a base plate 430, on which a bottom-touching wheel 440 is connected. The height of the bottom-touching wheel 440 is lower than the height of the propeller. The bottom-touching wheel 440 is used to contact the bottom of the water. The base plate 430 facilitates the installation of the bottom-touching wheel 440. When facing the slope of the bottom, the bottom-touching wheel 440 can push the deflector block 200 to deflect, causing the propeller to tilt upwards and preventing the propeller from hitting the bottom. It should be understood that the bottom-touching wheel 440 needs to remove the restriction on the deflector block 200 during use, allowing the deflector block 200 to deflect freely. At this time, the bottom-touching wheel 440, which is relatively close to the slope of the bottom, The first contact can push the deflector 200 to deflect, causing the propeller to swing and preventing it from hitting the sand and rocks on the bottom. Of course, during the launching process, the bottom wheel 440 can also provide some support to protect the propeller. In some other embodiments, the bottom wheel 440 can be completely removed or replaced with a bottom-touching rod. The bottom-touching rod can also achieve the same technical effect. Alternatively, the buoyancy can be increased by inflating the folding airbag 420, thereby causing the propeller to float and avoid touching the bottom. In this case, it is not necessary to fix the deflector 200, allowing the propeller to float adaptively.

[0044] In some embodiments, the buoyancy adjustment unit 700 includes an inflation box 710 and a piston 720. The inflation box 710 is disposed on the mounting body 100, and the piston 720 is slidably connected to the inner cavity of the inflation box 710, dividing the inner cavity of the inflation box 710 into an air chamber 711 and a power chamber 712. The air chamber 711 is connected to the folded airbag 420 via a hose, and the piston 720 is connected to the inner wall of the inflation box 710 via a spring 713. The spring 713 is housed in the power chamber 712 and is used to drive the piston 720. The piston 720 is in a predetermined position. The power chamber 712 is externally connected to a driving air source, which drives the piston 720 to move. The buoyancy adjustment unit 700 has a simple structure, using a spring 713 to maintain the position of the piston 720, ensuring that the folding airbag 420 is filled with a predetermined amount of gas, maintaining the propeller in a semi-submerged state. Simultaneously, the spring 713 can also reset the folding airbag 420 when it fluctuates. In essence, the predetermined position means that the piston 720 just allows the folding airbag 420 to maintain a predetermined amount of gas, thus... The propeller is in a semi-submerged state. The air volume in the folding airbag 420 is dynamically balanced by the spring 713. After the angle and depth are adjusted, the deflection block 200 needs to be locked. Alternatively, an additional locking mechanism can be added to lock the lifting frame 300. For example, a plug can be set to block the gap of the sliding of the lifting frame 300, or a tightening bolt can be set on the deflection block 200 to tighten the lifting frame 300, or the tightening bolt can be directly threaded to the lifting frame 300 to fix the lifting frame 300. Furthermore, when the elevator 300 is not fixed, the propeller can be kept in a semi-submerged state because the folding airbag 420 is filled with a predetermined amount of gas. During navigation, the folding airbag 420 rises and falls with the waves, and the propeller can quickly return to the semi-submerged state due to the buoyancy. This process simulates the operation of a human hand to keep the propeller in a semi-submerged state. In addition, a damping pad can be set at the sliding connection between the elevator 300 and the deflection block 200 so that the sliding of the elevator 300 in the deflection block 200 is damped.

[0045] Understandably, the driving air source is a common air pump.

[0046] Reference Figure 2 The tilt adjustment unit 800 includes a bracket 810, a push rod 820, a drive screw 830, and a handwheel 840. The bracket 810 is mounted on the mounting body 100. The push rod 820 is slidably connected to the bracket 810. One end of the push rod 820 is configured to push the deflection block 200. The other end of the push rod 820 is threadedly connected to the drive screw 830. One end of the drive screw 830 is rotatably connected to the bracket 810. The other end of the drive screw 830 is connected to the handwheel 840. The tilt adjustment unit 800 uses the push rod 820 and the drive screw 830 to realize stepless adjustment of the deflection block 200, which facilitates active driving of the deflection block 200 to deflect.

[0047] In some embodiments, a connecting arm 210 is hinged to the deflection block 200. The connecting arm 210 is detachably hinged to one end of the push rod 820. The connecting arm 210 provides a higher degree of freedom in the connection between the deflection block 200 and the push rod 820, making it easier for the deflection block 200 to rotate.

[0048] Reference Figure 3 It also includes a locking element 900, which is disposed on the mounting body 100 and is used to lock the deflection block 200.

[0049] In some embodiments, the deflection block 200 is connected to the rotating shaft 220, which is rotatably connected to the mounting body 100. The locking member 900 includes a brake pad 910, which covers the rotating shaft 220. The brake pad 910 is driven by a braking power component, which drives the brake pad 910 to brake the rotating shaft 220. The locking member 900 has a simple structure, making it easy to lock the deflection block 200 to position the propeller angle. It can be understood that the brake pad 910 is mounted on a clamp, which clamps the rotating shaft 220. The open end of the clamp is provided with a bolt and a nut. The clamping of the clamp is achieved by tightening the bolt and nut. The bolt is connected to the mounting body 100. The braking power component is a common motor, whose rotating shaft is driven by a nut. The motor outputs torque to screw the nut into the bolt, thereby achieving the clamping of the clamp and causing the brake pad 910 to brake the rotating shaft 220.

[0050] It should be noted that the upper end of the lifting frame 300 is provided with a receiving groove 310, which is used to receive the counterweight.

[0051] According to a second aspect of the present invention, a boat includes a hull and a semi-submerged oar mechanism, with a mounting body 100 disposed on the hull.

[0052] It has at least the following beneficial effects: This vessel has all the beneficial effects brought about by the above-mentioned semi-submerged propeller mechanism, which will not be repeated here.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] Of course, the present invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
