Description

Technical Field

[0001] The present invention relates to the field of ship power generation, and in particular to an energy-saving power generation device for a ship and a ship. Background Art

[0002] The principle of ship power generation is mainly the process of converting mechanical energy or chemical energy into electrical energy. Some existing ships are driven by propellers. The propellers generate vortex water flow during rotation. The mechanical energy of the vortex water flow fluctuations is converted into electrical energy storage to achieve autonomous power generation. However, due to the uneven strength of water flow fluctuations, there are unstable factors in the energy conversion process.

[0015] A ship comprises the above-mentioned energy-saving power generation device for a ship.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention stably transmits the power of the rotating ring through the transmission component. The rotation of the propeller generates a vortex water flow that acts on the power sail. The power sail drives the rotating ring to rotate. The power of the rotating ring is stably controlled to be input into the power generation component through the gear transmission structure such as the power gear ring, the lower transmission gear, the upper transmission gear, the sun gear, the planetary gear and the ring gear. The planetary transmission structure shares the load with multiple planetary gears and has a high load-bearing capacity and torque transmission capacity, which enables it to maintain stable working performance in high-power transmission, reduce the interference of water flow fluctuations on power transmission, and improve energy conversion efficiency.

[0018] 2. The present invention is provided with a buffer component that can reduce the polarization force of the rotating ring. Affected by the fluctuation of water flow, the rotating ring generates a certain polarization force during the rotation process. The retaining frame and the buffer mechanism in the buffer component are elastically pressed onto the side of the rotating ring. The buffer mechanism compresses the buffer spring through the lateral movement of the telescopic column to effectively buffer the polarization force of the rotating ring, thereby further maintaining the stability of the power transmitted by the rotating ring.

[0019] 3. The present invention is provided with a speed stabilizing component to adjust the abnormal state of power speed change. The rotating ring transmits power to the lower transmission gear, and the speed change is detected in real time by the speed sensor connected to the lower transmission gear. When the speed change gradient is large, the retaining frames on both sides of the rotating ring are controlled by the speed stabilizing component to be pressed toward the circular slide rail, and the resistance to the rotation of the rotating ring is increased by increasing the pressing force, thereby avoiding the situation where the power generation component demagnetizes due to the large change in the rotating ring speed, avoiding the terminal phenomenon of autonomous power generation, and improving the continuity and stability of energy conversion.

DETAILED DESCRIPTION

[0038] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] See also Figure 1-Figure 5 As shown, an energy-saving power generation device for a ship and a ship, comprising a water entry cover 11 installed on the ship and a propeller 12 rotatably installed in the water entry cover 11, the energy-saving power generation device also includes a protective ring 21 fixed in the water entry cover 11, a rotating ring 22 rotatably installed in the protective ring 21, and a power sail 23 distributed on the inner wall of the rotating ring 22 about the central axis of the protective ring 21; the rotating ring 22 and the power sail 23 are installed at the inlet end of the water entry cover 11, the power sail 23 is obliquely connected to the rotating ring 22, and the power sail 23 is distributed in front of the propeller 12; a transmission cover 31 is fixed through the water entry cover 11, a transmission assembly 32 for transmitting power of the rotating ring 22 is provided in the transmission cover 31, and a power generation assembly 33 connected to the transmission assembly 32 and controlling power generation is installed on the transmission cover 31.

[0040] The water entry hood 11 is installed on the ship. When the ship is sailing on the water, the water entry hood 11 penetrates below the water level to control the rotation of the propeller 12 in the water entry hood 11. The rotation of the propeller 12 generates power to cause the water flow to vortex and rotate. The vortex-rotating water flow acts on the power sail 23 at the entrance of the water entry hood 11. The power sail 23 is connected to the rotating ring 22 to produce a certain inclination angle. The vortex-rotating water flow pushes the power sail 23 to rotate in a circle, thereby causing the rotating ring 22 to rotate. The power of the rotating ring 22 is transmitted to the power generation component 33 through the transmission component 32, so that the power generation component 33 generates electricity autonomously.

[0041] See also Figure 2 , Figure 5 , Figure 8 and Fig. 9As shown, the power generation assembly 33 includes a shell 331 fixed on the transmission cover 31, a stator 332 is fixed in the shell 331, a coil 333 is fixed on the stator 332, a rotor 334 is rotatably mounted inside the shell 331, and an input shaft 335 is rotatably mounted outside the shell 331, and the input shaft 335 is coaxially connected to the rotor 334.

[0042] The power of the rotating ring 22 is transmitted to the input shaft 335 through the transmission assembly 32, and the input shaft 335 drives the rotor 334 to rotate in the housing 331. Magnetic lines of force are formed between the rotor 334 and the stator 332. When the rotor 334 rotates, the coil 333 cuts the magnetic lines of force, and an induced electromotive force is generated in the coil 333, thereby generating current, thereby achieving the purpose of converting mechanical energy into electrical energy.

[0043] See also Figure 1-Figure 8 As shown, the transmission assembly 32 includes a power gear ring 321 coaxially sleeved on the rotating ring 22, a lower transmission gear 322 meshing with the power gear ring 321 is rotatably installed in the transmission cover 31, and an upper transmission gear 323 meshing with the lower transmission gear 322 is also rotatably installed in the transmission cover 31, and the central axis of the upper transmission gear 323 is colinear with the central axis of the input shaft 335; a sun gear 324 is coaxially fixed on the upper transmission gear 323, and three groups of planetary gears 325 are meshingly connected to the outside of the sun gear 324 along the circumferential direction, and the three groups of planetary gears 325 are meshingly connected to the outside of the ring gear 326, and the ring gear 326 is fixedly installed in the transmission cover 31; a planet carrier 327 is rotatably installed on the three groups of planetary gears 325, and the planet carrier 327 is coaxially fixedly connected to the input shaft 335.

[0044] When the rotating ring 22 is rotated by the force of the vortex water flow, it drives the external coaxially fixed power gear ring 321 to rotate synchronously. The power gear ring 321 controls the corresponding rotation of the lower transmission gear 322 through meshing transmission. The lower transmission gear 322 controls the upper transmission gear 323 to rotate through meshing transmission. The sun gear 324 fixed on the upper transmission gear 323 rotates synchronously with it. The sun gear 324 controls the multiple planetary gears 325 distributed on the side circumference to slow down and rotate through meshing transmission. The outer side of the planetary gear 325 is meshed with the ring gear 326. Under the action of meshing transmission, the planetary gear 325 is controlled to rotate in a circle, thereby controlling the rotation of the planet carrier 327. The planet carrier 327 is fixedly connected to the input shaft 335 to provide power for the input shaft 335, thereby realizing the conversion of mechanical energy into electrical energy storage.

[0045] The multi-gear transmission structure can improve the stability of power transmission and reduce the interference of water flow fluctuations. Through the meshing transmission structure of the planetary gear 325, the sun gear 324 and the ring gear 326, multiple planetary gears 325 are meshed and distributed outside the sun gear 324. The rotation of the planetary gear 325 can share the load, has a higher load-bearing capacity and torque transmission capacity, and further maintains the stability of power transmission.

[0046] See also Figure 5 As shown, a rotation speed sensor 4 for real-time rotation speed detection is coaxially connected to the lower transmission gear 322 , and the rotation speed sensor 4 is fixedly installed in the transmission cover 31 .

[0047] The rotating ring 22 rotates through the meshing transmission structure of the power gear ring 321 and the lower transmission gear 322, which can control the rotation of the lower transmission gear 322. The rotating ring 22 is affected by changes in water quality or changes in the sailing speed of the ship, and its rotation speed fluctuates. The rotating ring 22 controls the rotation speed of the lower transmission gear 322 to also change. The rotation speed sensor 4 can detect the change in the rotation speed of the lower transmission gear 322 in real time, so as to timely adjust the rotation speed of the rotating ring 22 to avoid excessive changes in the rotation speed of the rotating ring 22.

[0048] See also Figure 8 , Figure 10-12 As shown, two groups of buffer components 5 for buffering vibration force and maintaining stable power input are symmetrically arranged in the protective ring 21 about the rotating ring 22.

[0049] The buffer components 5 are distributed on both sides of the rotating ring 22. When the rotating ring 22 rotates, it is affected by water waves to generate polarization force. The buffer components 5 can effectively buffer the polarization force of the rotating ring 22 to keep the rotating ring 22 stably rotating to transmit power.

[0050] See also Figure 10-12 As shown, the buffer assembly 5 includes annular slide rails 51 fixed on both sides of the rotating ring 22, a plurality of slide rods 52 are fixed in the protective ring 21, a retaining frame 53 is slidably mounted on the slide rods 52, and the retaining frame 53 is coaxially distributed with the annular slide rail 51; a plurality of buffer mechanisms 54 are arranged on the retaining frame 53 about the circumference of its own axis, and the buffer mechanism 54 is snap-connected to the annular slide rail 51.

[0051] The buffer mechanism 54 on the retaining frame 53 is circumferentially engaged and distributed on the annular slide rail 51. When the rotating ring 22 rotates, the rotating ring 22 drives the annular slide rails 51 on both sides to rotate synchronously. The annular slide rail 51 is engaged with the buffer mechanism 54 and rotates. When the rotating ring 22 rotates to generate polarization force, the rotating ring 22 transfers the polarization force to the annular slide rail 51. The buffer mechanism 54 is engaged with the annular slide rail 51 and effectively buffers the polarization force through the elastic structure, thereby reducing the interference of water flow fluctuations, keeping the annular slide rail 51 and the rotating ring 22 able to rotate stably, and improving the efficiency of power transmission of the rotating ring 22.

[0052] See also Figure 11-Figure 14 As shown, the buffer mechanism 54 includes a fixed seat 541 fixed on the retaining frame 53, a telescopic column 542 is slidably connected in the fixed seat 541, a buffer spring 543 is connected between the telescopic column 542 and the fixed seat 541, and a ball 544 is rotatably installed in the telescopic column 542, and the ball 544 is engaged in the annular slide rail 51 and rolls.

[0053] When the rotating ring 22 and the annular slide rail 51 rotate, the ball 544 is engaged in the annular slide rail 51 and rolls. When the rotating ring 22 and the annular slide rail 51 rotate to generate polarization, the polarization force is transmitted to the ball 544. The ball 544 pushes the telescopic column 542 to move telescopically on the fixed seat 541. When the telescopic column 542 moves in a directional manner, the buffer spring 543 is compressed. The polarization force is elastically buffered by the buffer spring 543, thereby maintaining the stable rotation of the annular slide rail 51 and the rotating ring 22.

[0054] See also Figure 8 , Fig.10 , Fig.15 and Fig.16 As shown, a speed stabilizing component 6 is provided in the transmission cover 31 for controlling the relative movement of the retaining frames 53 on both sides of the rotating ring 22 so as to stabilize the rotation speed of the rotating ring 22 .

[0055] The rotation speed of the lower transmission gear 322 is detected in real time by the rotation speed sensor 4, so as to analyze the rotation speed change of the rotating ring 22. If the rotation speed change gradient of the rotating ring 22 is large, the two sets of retaining frames 53 are controlled by the speed stabilizing component 6 to move closer to the rotating ring 22, so as to reduce the rotation speed of the rotating ring 22 and avoid the phenomenon that the sudden high-speed rotation of the rotating ring 22 causes the demagnetization of the power generation component 33.

[0056] See also Fig.15 and Fig.16As shown, the speed stabilizing component 6 includes a moving plate 61 fixed on the retaining frame 53, and a vertical frame 62 is fixedly installed on the moving plate 61; a support frame 63 is fixedly installed in the transmission cover 31, and an electric drive telescopic rod 64 is fixedly installed in the support frame 63, and a lifting frame 65 is fixedly connected to the output end of the electric drive telescopic rod 64; a sliding groove 66 is obliquely opened on the lifting frame 65, and a sliding column 67 is slidably connected in the sliding groove 66, and the sliding column 67 is fixedly installed on the vertical frame 62.

[0057] When the rotating ring 22 suddenly rotates at a high speed, the speed stabilizing component 6 is driven to adjust the speed of the rotating ring 22, and the electric drive telescopic rod 64 is operated to control the lifting frame 65 to move downward. The slide column 67 slides in the slide groove 66 in the lifting frame 65. Since the slide groove 66 is inclined and opened on the lifting frame 65, when the lifting frame 65 moves downward, the slide column 67 will be displaced horizontally. The slide column 67 drives the vertical frame 62 and the moving piece 61 to move horizontally synchronously. The moving piece 61 is fixed on the retaining frame 53 to control its synchronous movement, so that the two sets of retaining frames are 53 moves toward the rotating ring 22, the retaining frame 53 drives the fixed seat 541 to move synchronously, the fixed seat 541 compresses the buffer spring 543, so that the ball 544 is pressed tightly in the circular slide rail 51, and the pressing force of the ball 544 increases the rotational friction of the circular slide rail 51, and generates resistance to the rotation of the circular slide rail 51 and the rotating ring 22, thereby limiting the rotation speed of the rotating ring 22, avoiding the situation where the gradient of the rotation speed change of the rotating ring 22 is too large and causes the demagnetization of the power generation component 33, and improving the continuity and stability of energy conversion.

[0058] A ship comprises the above-mentioned energy-saving power generation device for a ship.

[0059] Working principle: the water entry cover 11 penetrates into the water, and the propeller 12 in the water entry cover 11 is controlled to rotate to drive the ship to sail on the water surface. The rotation of the propeller 12 continuously generates a vortex of water flow. The vortex of water flow acts on the power sail 23 in the water entry cover 11 when the ship moves forward. The power sail 23 has a certain inclination angle. When the vortex of water flow acts on the surface of the inclined power sail 23, it pushes the power sail 23 to move. There are multiple power sails 23 on the circumference of the rotating ring 22. The multiple power sails 23 are synchronously controlled by the thrust of the vortex of water flow to rotate the rotating ring 22.

[0060] The rotation of the rotating ring 22 drives the external fixed power gear ring 321 to rotate synchronously. Under the meshing transmission action of the power gear ring 321, the lower transmission gear 322, and the upper transmission gear 323, the power of the rotating ring 22 is transmitted to the upper transmission gear 323. The multi-gear transmission enables the power of the rotating ring 22 to be transmitted relatively stably. When the upper transmission gear 323 rotates, the sun gear 324 is driven to rotate synchronously. The planetary gears 325 circumferentially distributed outside the sun gear 324 rotate under the meshing transmission action. The planetary gears 325 rotate circumferentially inside the ring gear 326 to control the planetary carrier 327 to rotate. The planetary carrier 327 is fixedly connected to the input shaft 335 in the power generation component 33 to drive the input shaft 335 to rotate. The meshing structure of the sun gear 324, the planetary gears 325 and the ring gear 326 forms a planetary reduction structure. The multiple planetary gears 325 can share the load and have a high load-bearing capacity and torque transmission capacity, further maintaining the stable transmission of the power of the rotating ring 22 to the input shaft 335.

[0061] Since there are many unstable factors in the water environment and the speed of the ship will also affect the size of the surrounding water fluctuations, the water fluctuations cause polarization when the rotating ring 22 rotates. When the rotating ring 22 rotates, it drives the external fixed circular slide 51 to rotate synchronously, and the polarization force on the rotating ring 22 is transmitted to the circular slide 51. The circular slide 51 is circularly connected with a buffer mechanism 54. The ball 544 in the buffer mechanism 54 is engaged and rolls in the circular slide 51. When the circular slide 51 rotates, the ball 544 absorbs part of the polarization force. The ball 544 pushes the telescopic column 542 to slide in the fixed seat 541. The telescopic column 542 compresses the buffer spring 543 in the fixed seat 541. The elastic buffering effect of the buffer spring 543 can effectively buffer the polarization force, so that the circular slide 51 and the rotating ring 22 can rotate stably.

[0062] When the rotating ring 22 rotates, the lower transmission gear 322 is driven to rotate through the power gear ring 321. The speed sensor 4 detects the speed of the power gear ring 321 in real time, so as to analyze the speed change of the rotating ring 22. Due to changes in water quality and the sailing speed of the ship, the speed of the rotating ring 22 may suddenly fluctuate greatly. If the rotating ring 22 suddenly rotates at a high speed, the power generation component 33 will be demagnetized, affecting the efficiency and continuity of energy transfer.

[0063] When it is detected that the rotating ring 22 suddenly rotates at a high speed, the driving speed stabilizing component 6 controls the relative movement of the retaining frames 53 distributed on both sides of the rotating ring 22, and the electric drive telescopic rod 64 in the running speed stabilizing component 6 pushes the lifting frame 65 to move downward, and the slide column 67 is engaged in the slide groove 66 in the lifting frame 65 to slide and move, and the inclined slide groove 66 pushes the slide column 67 to move horizontally, so that the slide column 67, the frame 62 and the moving piece 61 move horizontally, and the moving piece 61 drives the retaining frame 53 to move toward the rotating ring 22, and the retaining frame 53 is moved to the rotating ring 22. The holder 53 is pressed together with the fixing seat 541 and the buffer spring 543, and the elastic pressure on the ball 544 is increased, so that the ball 544 is pressed tightly against the circular slide rail 51. The increased pressure between the ball 544 and the circular slide rail 51 increases the resistance to the rotation of the rotating ring 22, thereby causing the rotating ring 22 to rotate slowly, thereby achieving the control of the rotation speed of the rotating ring 22, avoiding the demagnetization of the electromagnetic power generation component 33 due to the sudden high-speed rotation of the rotating ring 22, and ensuring that the power generation component 33 can continuously convert electrical energy.

[0064] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
