Description

Technical Field

[0001] This invention relates to the field of wind energy harvesting and utilization devices, and more particularly to marine wind energy harvesting and utilization devices. Background Technology

[0002] With the development of the shipbuilding industry, the number of ships and the frequency of use have increased. Traditional ships use non-renewable resources such as diesel as propulsion, but the use of such resources will pollute the environment. With the development of the new energy industry, ships have begun to use wind power to replace part of the power. Wind power generation is used to utilize the wind energy at sea and convert it into electricity for use and storage, which can reduce the consumption of resources such as diesel.

[0003] A search revealed Chinese patent CN109139377A, which discloses a marine wind energy harvesting and utilization device. This device includes a vertical shaft fan blade, a fan blade connecting frame, a positioning pin, a flange, a fan rotating shaft, a sleeve, a coupling, a vertical bearing with a mounting seat, a No. I drive shaft, a small spur gear, a No. II drive shaft, a large spur gear, a small bevel gear, a large bevel gear, a No. IV drive shaft, a power propeller, a deck, a bottom plate, side plates, a battery, a switch button, shipboard electrical equipment, wires, a generator, a No. I electromagnetic clutch, a propeller rotating shaft, a No. II electromagnetic clutch, a motor bracket, a voltage stabilizing module, and a vertical bearing with a mounting seat. It employs a two-stage reduction mechanical mechanism to transmit kinetic energy, requiring minimal starting wind force. Furthermore, this device directly transfers the kinetic energy converted from wind energy to the propeller through a mechanical structure, reducing energy conversion and thus improving energy utilization efficiency. However, this solution still has the following shortcomings in practical use: To efficiently capture wind energy, marine wind power collection and generation devices are mostly deployed in open areas at high altitudes on ships. However, wind speeds at sea are generally higher than on land, and due to the complexity of the marine environment, wind speeds are difficult to monitor accurately in advance. During ship navigation, wind speeds can easily exceed the rated range of the device. When the wind speed exceeds the rated value, the core components of the device, such as blades and shafts, will be subjected to instantaneous overload stress. This will not only lead to increased component vibration and accumulated fatigue damage, shortening the service life, but in extreme cases, it may also cause structural failures such as blade breakage and tower deformation. This will not only disrupt the normal operation of the power generation device, but also pose a direct threat to the safety of ship navigation.

[0004] Therefore, a new marine wind energy harvesting and utilization device needs to be designed to solve the above problems. Summary of the Invention

Fixed blades are fixedly connected to the outer surface of the stepped shaft, and movable blades are movably connected to the outer surface of the stepped shaft. The opening and closing assembly includes a toothed ring movably disposed inside the stepped shaft, a round rod movably inserted into the outer surface of the stepped shaft, transmission wheels fixedly connected to both ends of the round rod, a clamping plate fixedly connected to the upper surface of the base, a rack embedded in the upper outer surface of the clamping plate, and a guide plate fixedly connected to the upper part of the clamping plate.

[0007] As a preferred embodiment of the present invention, the toothed ring is fixedly connected to the movable blade, the transmission wheel connected to one end of the round rod extending into the stepped shaft is meshed with the toothed ring, and the transmission wheel connected to one end of the round rod extending out of the stepped shaft is meshed with the rack.

[0008] As a preferred embodiment of the present invention, a pin is movably inserted into the outer surface of the stepped shaft, the pin is engaged in the middle of the movable leaf, a spring is sleeved on the outer surface of the pin, and the end of the pin slides along the outer surface of the guide plate.

[0009] As a preferred embodiment of the present invention, a lifting transmission rod is movably connected inside the threaded column. A first bevel gear is fixedly connected to one end of the lifting transmission rod that extends into the housing. A second bevel gear is fixedly connected to one end of the stepped shaft that extends into the housing. The first bevel gear and the second bevel gear are meshed together. The bottom end of the lifting transmission rod is rotatably connected to the inside of the base and is connected to a generator set.

[0010] As a preferred embodiment of the present invention, the lifting assembly includes a threaded tube rotatably connected to the middle of the base, the threaded tube being threaded onto the outer surface of the threaded column, a worm gear being fixedly fitted onto the outer surface of the threaded tube, a motor being provided on the upper and lower surfaces of the base, and a worm being fixedly connected to the drive end of the motor, the worm being meshed with the worm gear.

[0011] As a preferred embodiment of the present invention, a counterweight is fixedly connected to the lower surface of the stepped shaft, and a groove is provided on the upper surface of the card plate.

[0012] As a preferred embodiment of the present invention, the slow-stop component includes an electromagnet disposed on the upper part of the housing, a hollow column fixedly connected to the upper surface of the first bevel gear, a vertical rod movably inserted through the upper surface of the hollow column, an iron sheet fixedly sleeved on the outer surface of the vertical rod, and the iron sheet being magnetically connected to the electromagnet.

[0013] As a preferred embodiment of the present invention, a circular ring is fixedly connected inside the hollow column, a rubber ring is provided on the inner wall of the circular ring, and an elliptical plate is fixedly connected to the bottom end of the vertical rod.

[0014] As a preferred embodiment of the present invention, the stabilizing component includes a shaft support fixedly connected to the upper surface of the lower layer of the base, a rocker arm rotatably connected to the outer surface of the shaft support, a clamping plate hinged to the end of the rocker arm, and a torsion spring sleeved on the outer surface of the shaft support.

[0015] As a preferred embodiment of the present invention, a collar is fixedly sleeved on the outer surface of the threaded column, a positioning rod is fixedly connected to the outer surface of the collar, the positioning rod passes through the upper part of the base, and a pressure block is fixedly connected to the bottom end of the positioning rod.

[0016] The present invention has the following beneficial effects: 1. In this invention, by setting up an opening and closing component and a lifting component to cooperate, the housing and blades are driven to descend. The movable blades are retracted to a vertical state through a transmission mechanism and locked in place by a counterweight and a locking plate. At the same time, the overall height of the device is reduced, which greatly reduces the windward surface and wind load, and prevents the blades, shafts and other components from vibrating, breaking or deforming due to overload stress, thus ensuring the safety of ship navigation and the device. After the wind recovers, the structure reverses the linkage to realize the automatic unfolding and locking of the blades, quickly restoring the complete blade shape to efficiently collect wind energy, thus taking into account both the safety of strong wind protection and the continuity of wind energy utilization. 2. In this invention, by setting up a slow-stop component, after the electromagnet is de-energized, the elliptical plate is precisely triggered by the gravity of the iron plate and the vertical rod to fall between the two rubber rings of the circular ring. Utilizing the unique structure of the rubber rings, which are thin at both ends and thick in the middle, the resistance of the elliptical plate gradually increases when they slide relative to each other. This not only generates a buffering effect through the friction and deformation of the rubber rings, but also effectively counteracts the inertial rotation of the hollow column, assisting the power generation component to stop quickly and smoothly. This avoids continuous idling or component impact damage caused by residual power, adapts to complex marine environments, and greatly improves the safety and stability of the device during shutdown. 3. In this invention, by setting a stabilizing component, when the threaded column descends, the collar moves down synchronously and the positioning rod passes through the base for limitation. The pressure block presses the rocker plate to rotate around the belt shaft support and squeezes the torsion spring, causing the clamping plate to fit against the outer surface of the threaded column. Through the oblique support of multiple clamping plates and the rocker plate, the pressure of the pressure block is used to achieve a stable clamping around the threaded column, which greatly improves the connection and support strength between the threaded column and the base, effectively resists strong winds, and ensures the structural stability of the device after it is lowered.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Example 1: This example describes a marine wind energy harvesting and utilization device disclosed in this embodiment, referring to... Figures 1 to 10 It includes a base 1, a threaded column 2 movably connected to the middle of the base 1, a housing 3 fixedly connected to the top of the threaded column 2, a power generation component 4 provided on the outer surface of the housing 3, a lifting component 5 provided on the outer surface of the threaded column 2, an opening and closing component 6 provided on the outer surface of the housing 3, a slow-stop component 7 provided inside the housing 3, and a stabilizing component 8 provided inside the base 1. The power generation component 4 includes a stepped shaft 41 that is movably inserted into the outer surface of the housing 3. A fixed blade 42 is fixedly connected to the outer surface of the stepped shaft 41, and a movable blade 43 is movably connected to the outer surface of the stepped shaft 41. Both the fixed blade 42 and the movable blade 43 are wind turbine blades. Two movable blades 43 and one fixed blade 42 are installed together on the outer surface of the stepped shaft 41 to form a complete wind turbine rotor. A lifting transmission rod 44 is movably connected inside the threaded column 2. A first bevel gear 45 is fixedly connected to one end of the lifting transmission rod 44 that extends into the housing 3. A second bevel gear 46 is fixedly connected to one end of the stepped shaft 41 that extends into the housing 3. The first bevel gear 45 and the second bevel gear 46 are meshed. The bottom end of the lifting transmission rod 44 is rotatably connected to the inside of the base 1 and is connected to the generator set 47. The transmission and storage of wind power are existing technologies well known to those skilled in the art and will not be elaborated on here.

[0021] The implementation principle of this embodiment is as follows: A wind energy harvesting and power generation device is installed on the ship, and the device is fixed using the base 1 as a base. When collecting wind energy, the wind on the sea surface blows the fixed blade 42 and the movable blade 43, which in turn drives the stepped shaft 41 to rotate under the action of the airflow. Through the transmission of the first bevel gear 45 and the second bevel gear 46, the lifting transmission rod 44 is driven to rotate, thereby driving the generator set 47 to operate, collecting wind energy and converting it into electrical energy for use. In addition, three sets of blades are set around the shell 3, which can utilize wind power from multiple directions, improving the practicality of the device. When the wind speed exceeds the limit, the device can be used to generate electricity. Within the rated range, the lifting assembly 5 lowers the housing 3 and fixed blade 42 to a position close to the base 1. During this process, the slow-stop assembly 7 can buffer and stop the rotating lifting transmission rod 44. Furthermore, the opening and closing assembly 6 can rotate the movable blade 43 to a position flush with the fixed blade 42, ensuring that all blades are in a downward position, thus reducing the impact of strong winds on the device. The stabilizing assembly 8 can provide multi-point support for the device after descent, improving its stability. All exposed structures are treated with waterproof and rust-proof measures to cope with marine climate conditions.

[0022] Example 2: Based on Example 1, this example discloses a marine wind energy harvesting and utilization device, such as... Figures 2 to 7As shown, the opening and closing assembly 6 includes a gear ring 61 movably disposed inside the stepped shaft 41. A round rod 62 is movably inserted through the outer surface of the stepped shaft 41. Both ends of the round rod 62 are fixedly connected to transmission wheels 63. A clamping plate 66 is fixedly connected to the upper surface of the base 1. The clamping plate 66 consists of a vertical support plate and an upper semi-circular plate. A rack 67 is embedded in the upper outer surface of the clamping plate 66. A guide plate 68 is fixedly connected to the upper part of the clamping plate 66. The guide plate 68 is bent. The gear ring 61 is fixedly connected to the movable leaf 43. One end of the round rod 62 extends into the stepped shaft 41 and is connected to... The transmission wheel 63 is meshed with the gear ring 61. The transmission wheel 63 connected to the end of the round rod 62 extending into the stepped shaft 41 is meshed with the rack 67. A pin 64 is movably inserted into the outer surface of the stepped shaft 41. The pin 64 is engaged in the middle of the movable leaf 43. A spring 65 is sleeved on the outer surface of the pin 64. The spring 65 is embedded in a groove on the outer surface of the stepped shaft 41, which serves both to store and limit the movement. The end of the pin 64 slides along the outer surface of the guide plate 68. A counterweight 69 is fixedly connected to the lower surface of the stepped shaft 41. A groove 610 is opened on the upper surface of the clamping plate 66.

[0023] Reference Figures 3 to 6 The lifting assembly 5 includes a threaded tube 51 rotatably connected to the middle of the base 1. The threaded tube 51 is threaded onto the outer surface of the threaded post 2. A worm gear 52 is fixedly fitted onto the outer surface of the threaded tube 51. A motor 53 is provided on the upper and lower surfaces of the base 1. A worm 54 is fixedly connected to the drive end of the motor 53. The worm 54 is meshed with the worm gear 52.

[0024] The implementation principle of this embodiment is as follows: When the wind speed exceeds the rated range, the motor 53 drives the worm gear 54 to rotate, which in turn drives the worm wheel 52 to rotate, thereby driving the threaded tube 51 to rotate. During the rotation of the threaded tube 51, the threaded column 2 is driven to move downward, which in turn drives the lifting transmission rod 44 to retract and pull the housing 3 and other structures to move downward synchronously, thereby reducing the height of the housing 3 and the blades and reducing the impact of wind on the device. During the descent of the housing 3, the wind-driven effect on the movable blade 43 and the fixed blade 42 is reduced, and they tend to be stable. Under the action of the counterweight 69, the fixed blade 42 will be in a vertically downward state. Moving downward in this state, the end of the pin 64 will first contact the guide plate 68. Under the guidance of the guide plate 68, the pin 64 will be forced to move away from the step axis 41. The pin 64 will be pulled out from the middle of the movable blade 43 and stretch the spring 65. The two movable blades 43 will lose their limiting effect. Then, the transmission wheel 63 fixed at the end of the round rod 62 that extends out of the stepped shaft 41 will mesh with the rack 67 and rotate under the limitation of the rack 67. During the rotation of the round rod 62, the transmission wheel 63 fixed at the end that extends into the stepped shaft 41 will drive the gear ring 61 to rotate, which will drive the movable shaft to rotate downward until it is parallel to the fixed shaft. This makes the blades on the outer surface of each stepped shaft 41 in a vertically downward retracted state until the stepped shaft 41 is retracted into the clamping plate 66 and the counterweight 69 is engaged in the groove 610. This state is less affected by wind force, greatly reducing the windward surface and wind load, and preventing the blades, shafts and other components from vibrating, breaking or deforming due to overload stress, thus ensuring the safety of ship navigation and equipment.

[0025] Once the wind force decreases to within the operating range of the device, the motor 53 drives the worm gear 54 to rotate in the opposite direction, which in turn drives the threaded column 2 to move upward. During this process, the transmission wheel 63, limited by the rack 67, drives the gear ring 61 to rotate in the opposite direction, which in turn drives the movable blade 43 to rotate outward and unfold. After the transmission wheel 63 passes the rack 67, the pin 64 slides to the bend of the guide plate 68, and the spring 65 contracts to pull the pin 64 to slide into the stepped shaft 41. The pin 64 is engaged inside the movable blade 43, locking the position of the movable blade 43. At this time, the two movable blades 43 and the fixed blade 42 form a complete wind turbine blade state for wind energy collection and utilization, taking into account both the safety of strong wind protection and the continuity of wind energy utilization.

[0026] Example 3: Based on Example 1, this example discloses a marine wind energy harvesting and utilization device, such as... Figure 8 and Figure 9As shown, the slow-stop component 7 includes an electromagnet 71 located on the upper part of the housing 3. A hollow column 72 is fixedly connected to the upper surface of the first bevel gear 45. A vertical rod 73 is movably inserted through the upper surface of the hollow column 72. The upper limit of the vertical rod 73 is movably engaged inside the electromagnet 71, ensuring that the vertical rod 73 can only slide up and down. An iron sheet 74 is fixedly sleeved on the outer surface of the vertical rod 73. The iron sheet 74 is magnetically connected to the electromagnet 71. A ring 76 is fixedly connected inside the hollow column 72. A rubber ring 77 is provided on the inner wall of the ring 76. The rubber ring 77 is composed of two rubber blocks that are thin at both ends and thick in the middle. An elliptical plate 75 is fixedly connected to the bottom end of the vertical rod 73. The long axis end of the elliptical plate 75 will push the rubber ring 77 during rotation.

[0027] Reference Figure 3 , Figure 6 and Figure 10 The stabilizing component 8 includes a shaft support 81 fixedly connected to the upper surface of the lower layer of the base 1. A rocker plate 82 is rotatably connected to the outer surface of the shaft support 81. A clamping plate 83 is hinged to the end of the rocker plate 82. A torsion spring 84 is sleeved on the outer surface of the shaft support 81. A collar 85 is fixedly sleeved on the outer surface of the threaded column 2. A positioning rod 86 is fixedly connected to the outer surface of the collar 85. The positioning rod 86 passes through the upper part of the base 1. A pressure block 87 is fixedly connected to the bottom end of the positioning rod 86.

[0028] The implementation principle of this embodiment is as follows: When the device needs to be lowered, the electromagnet 71 is de-energized, and the iron plate 74 loses the magnetic attraction of the electromagnet 71. Under the action of its own weight, the iron plate 74 and the vertical rod 73 will fall downwards. When the hollow column 72 rotates to the point where the elliptical plate 75 corresponds to the ring 76, the elliptical plate 75 will fall into the ring 76 and be positioned between the two rubber rings 77. Driven by inertia or residual power, the hollow column 72 will continue to rotate, and a relative rotation will occur between the hollow column 72 and the elliptical plate 75. The elliptical plate 75 will slide along the inner wall of the rubber ring 77. Due to the unique structural characteristics of the rubber ring 77, which is thin at both ends and thick in the middle, the elliptical plate 75 will not only be subject to the frictional force of the inner wall of the rubber ring 77 during the sliding process. The influence of the pressure will also cause the rubber ring 77 to deform. The sliding resistance of the elliptical plate 75 from the thin end of the rubber ring 77 to the thicker middle part will gradually increase, which will buffer and stop the rotation of the hollow column 72. This can counteract the inertial rotation, assist the power generation component 4 to stop quickly and smoothly, avoid continuous idling or component impact damage caused by residual power, adapt to the complex marine environment, and greatly improve the safety and stability of the device shutdown. When the device is raised and reused later, the electromagnet 71 will be energized to magnetically attract the iron plate 74, which will then pull the iron plate 74 and the vertical rod 73 upward until the elliptical plate 75 slides out from between the two rubber rings 77. After the hollow column 72 loses the limit of the elliptical plate 75, it can smoothly carry out the transmission.

[0029] As the threaded column 2 descends, the collar 85 fixedly fitted on its outer surface moves downwards accordingly. The positioning rod 86 penetrates the upper part of the base 1 to achieve a limiting effect when the threaded column 2 descends. The pressure block 87 at the bottom of the positioning rod 86 presses the rocker plate 82 after the threaded column 2 descends to the designated position. This pushes the rocker plate 82 to rotate around the shaft support 81. During the rotation of the rocker plate 82, it compresses the torsion spring 84. The end of the rocker plate 82 that is hinged to the clamp 83 will descend downwards. The clamp 83 will fit against the outer surface of the threaded column 2. Multiple clamps 83 and the rocker plate 82 simultaneously provide oblique support for the threaded column 2. The pressure of the pressure block 87 forces the clamp 83 to support the threaded column 2 from all sides, greatly improving the connection and support strength between the threaded column 2 and the base 1, thereby improving stability, effectively resisting strong winds, and ensuring the structural stability of the device after it is lowered. When the threaded column 2 rises, the pressure block 87 leaves the rocker plate 82, and the torsion spring 84 rebounds, causing the rocker plate 82 and the clamp 83 to return to their original positions.

[0030] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
