Description

Technical Field

[0001] This application relates to the field of wind power generation equipment technology, and in particular to a bladeless offshore wind power generation device. Background Technology

[0002] In the field of offshore wind power, traditional wind power generation equipment mainly relies on bladed rotors to capture wind energy and convert mechanical energy into electrical energy. These devices are usually large in size, and the blades generate significant mechanical stress during rotation, requiring high standards for structural support and installation environment. At the same time, they are prone to blade vibration, fatigue damage, and maintenance difficulties under strong winds or complex sea conditions. Existing equipment requires large bases and complex support systems for offshore installation, and there are certain safety risks for operators during inspection and maintenance. In addition, their adaptability to the marine environment is limited, and they are easily affected by wave surges, which affects the service life of the wind power generation equipment. Summary of the Invention

[0003] This application provides a bladeless offshore wind power generation device to reduce the requirements of the installation environment for wind power generation devices, while increasing the service life of wind power generation devices.

[0004] To achieve the above objectives, the main technical solutions adopted in this application include: This application provides an offshore bladeless wind power generation device, comprising: a base, a mounting frame, a power generation shaft, a power generation component, a bladeless wind turbine, a connecting frame, and a torsion spring. Along the height direction of the base, the top of the base has a first mounting surface. The mounting frame is mounted on the first mounting surface, and an installation space extending along the height direction of the base is formed within the mounting frame. The power generation shaft is mounted within the installation space. The power generation component is mounted on the mounting frame and connected to the power generation shaft. The bladeless wind turbine is sleeved outside the mounting frame and has rotational freedom relative to the mounting frame. The connecting frame is mounted on the power generation shaft, and at least partially extends outside the installation space, connecting the connecting frame to the bladeless wind turbine. The two ends of the torsion spring are respectively connected to the power generation shaft and the mounting frame. Under the action of the torsion spring, the power generation shaft can rotate clockwise or counterclockwise relative to the mounting frame.

[0005] Furthermore, the connecting frame includes a fixed bracket and a movable bracket. The fixed bracket is installed on the mounting frame, and the movable bracket is rotatably installed inside the fixed bracket. The movable bracket is connected to the bladeless wind turbine, and under the action of the bladeless wind turbine, the movable bracket rotates relative to the fixed bracket. One end of the torsion spring is connected to the mounting frame through the fixed bracket, and the other end of the torsion spring is connected to the generator shaft through the movable bracket.

[0006] Furthermore, the fixed bracket includes multiple connecting sleeves and multiple partitions. The multiple connecting sleeves are parallel to each other, and the axis of the connecting sleeves is parallel to the height direction of the base. The multiple partitions are perpendicular to the height direction of the base, and there is an installation gap between adjacent partitions. The torsion spring is located within the installation gap.

[0007] Furthermore, the movable support includes a connecting column and multiple isolation plates. The axis of the connecting column is parallel to the height direction of the base. The multiple isolation plates are evenly connected to the connecting column, and the multiple isolation plates are located in different installation gaps. The multiple isolation plates are connected to the generator shaft respectively.

[0008] Furthermore, the power generation shaft includes multiple shaft units, each of which is connected to an isolation plate.

[0009] Furthermore, connecting frames are installed at both ends of the rotating shaft unit along the height direction of the base; the power generation rotating shaft also includes a first main shaft and a second main shaft. Along the height direction of the base, the first main shaft and the second main shaft are respectively connected to both ends of the rotating shaft unit. The end of the first main shaft away from the rotating shaft unit is connected to the mounting frame, and the end of the second main shaft away from the rotating shaft unit is connected to the power generation component.

[0010] Furthermore, the movable support also includes a connecting rod and a connecting ring. One end of the connecting rod is connected to the isolation plate, and the other end of the connecting rod extends outside the mounting frame and is connected to the connecting ring. The movable support is connected to the bladeless impeller through the connecting ring.

[0011] Furthermore, the mounting frame includes a first end plate, a second end plate, and multiple uprights, the axes of which are parallel to the height direction of the base, and the multiple uprights enclose an installation space; along the height direction of the base, the first end plate and the second end plate are respectively installed at both ends of the uprights. Furthermore, the bladeless impeller includes a wind tunnel and a connecting tube, with the connecting tube installed inside the wind tunnel; multiple air ducts are formed on the wind tunnel, and the air ducts are inclined relative to the diameter of the wind tunnel.

[0012] Furthermore, the base includes a mounting column and an equipment platform. Along the height direction of the base, the mounting column is installed at the bottom of the equipment platform, and the mounting bracket is installed at the top of the equipment platform.

[0013] By combining external wind force with torsion springs, the generator shaft rotates clockwise or counterclockwise, resulting in a smaller rotation angle and reduced rotational speed. This reduces the risk of vibration in the generator equipment and extends its service life. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, as one implementation, this application provides an offshore bladeless wind power generation device, including a base 1, a mounting frame 2, a power generation shaft 3, a power generation component 4, a bladeless wind turbine 5, a connecting frame 6, and a torsion spring 7. The base 1 is used to fix the offshore bladeless wind power generation device on the sea surface. The mounting frame 2 is used to install the components of the bladeless wind power generation device. The power generation shaft 3 is used to connect the bladeless wind turbine 5 and the power generation component 4. The bladeless wind turbine 5 drives the power generation shaft 3 to rotate, so that the power generation component 4 can generate electricity. The bladeless wind turbine 5 is used to convert wind energy into the mechanical energy of the bladeless wind turbine 5. The connecting frame 6 is used to connect the power generation shaft 3 and the bladeless wind turbine 5. The torsion spring 7 is used to drive the power generation shaft 3 to rotate clockwise or counterclockwise.

[0022] Specifically, along the height direction of the base 1, the top of the base 1 has a first mounting surface 101.

[0023] It should be noted that after the base 1 is installed, the first mounting surface 101 is always above the sea level.

[0024] Mounting bracket 2 is installed on the first mounting surface 101. Mounting bracket 2 has an installation space extending along the height direction of base 1. Power generation shaft 3 is installed in the installation space.

[0025] The power generation component 4 is mounted on the mounting bracket 2, and at least a portion of the power generation component 4 is located within the mounting space so as to facilitate the connection of the power generation component 4 with the power generation shaft 3.

[0026] The bladeless impeller 5 is mounted outside the mounting frame 2. Under the action of external wind force, the bladeless impeller 5 has the rotational freedom to rotate relative to the mounting frame 2.

[0027] The connecting frame 6 is installed on the generator shaft 3, and the connecting frame 6 extends at least partially outside the installation space, so that the connecting frame 6 is connected to the bladeless wind turbine 5.

[0028] It should be noted that the installation space has a certain opening to allow the connecting frame 6 to extend from the installation space to the outside of the mounting frame 2, thereby connecting the bladeless wind turbine 5 to the generator shaft 3 via the connecting frame 6. Furthermore, due to the limitation of the opening in the installation space, the rotation angle of the connecting frame 6 is less than 180°.

[0029] The two ends of the torsion spring 7 are connected to the generator shaft 3 and the mounting bracket 2 respectively. Under the action of the torsion spring 7, the generator shaft 3 can rotate clockwise or counterclockwise relative to the mounting bracket 2.

[0030] The external wind force and the torsion spring 7 work together to make the generator shaft 3 rotate clockwise or counterclockwise, so that the rotation angle of the generator shaft 3 is small, reducing the speed of the generator shaft 3, thereby reducing the risk of vibration of the generator equipment and improving the service life of the generator equipment.

[0031] Specifically, under the action of external wind force, the bladeless wind turbine 5 drives the power generation shaft 3 to rotate clockwise through the connecting frame 6. During this process, the torsion spring 7 deforms and accumulates elastic energy. When the force exerted by the torsion spring 7 on the power generation shaft 3 is greater than the force exerted by the bladeless wind turbine 5 on the power generation shaft 3, the torsion spring 7 drives the power generation shaft 3 to rotate counterclockwise. Through the rotation of the power generation shaft 3, the power generation component 4 generates electricity, producing electrical energy.

[0032] It should be noted that, under the action of external wind force and torsion spring 7, the power generation shaft 3 always switches between forward and reverse rotation to realize the power generation component 4 generating electricity.

[0033] It should be further explained that the power generation component 4 generates electricity during the clockwise and / or counterclockwise rotation of the power generation shaft 3. That is, when the power generation shaft 3 rotates clockwise, the power generation component 4 generates electricity, and when the power generation shaft 3 rotates counterclockwise, the power generation component 4 does not generate electricity. Alternatively, when the power generation shaft 3 rotates counterclockwise, the power generation component 4 generates electricity, and when the power generation shaft 3 rotates clockwise, the power generation component 4 does not generate electricity. Or, the power generation component 4 can generate electricity whether the power generation shaft 3 rotates clockwise or counterclockwise.

[0034] To more clearly illustrate the technical solution of this application, the following definitions are provided: Figure 1 The up and down directions are shown. The height direction of base 1 is... Figure 1 The up and down directions are shown.

[0035] like Figure 4 As shown, as one implementation method, the mounting frame 2 includes a first end plate 201, a second end plate 202 and multiple columns 203. The axes of the multiple columns 203 are all parallel to the height direction of the base 1, and the multiple columns 203 enclose the installation space.

[0036] Specifically, in this implementation, the mounting frame 2 includes three columns 203, which together form a triangular prism-shaped mounting space. The three columns 203 are spaced apart, so that an opening is formed between adjacent columns 203 in the mounting space. The connecting frame 6 extends out of the mounting space through the opening.

[0037] It should be noted that the connecting frame 6 extends outside the installation space through the opening of the installation space. During the rotation of the connecting frame 6, the column 203 restricts the rotation angle of the connecting frame 6, so that the rotation angle of the connecting frame 6 is 110° to 115°.

[0038] Along the height direction of the base 1, the first end plate 201 and the second end plate 202 are respectively installed on the upper and lower ends of the column 203 so as to fix the three columns 203.

[0039] The upper end of the power generation shaft 3 is rotatably connected to the first end plate 201 via a bearing, the power generation component 4 is mounted on the second end plate 202, and the lower end of the power generation shaft 3 is connected to the power generation component 4.

[0040] Mounting bracket 2 includes multiple retaining plates 204, which are arranged along the height direction of base 1, and the generator shaft 3 is rotatably connected to the retaining plates 204 via bearings.

[0041] like Figure 2 and Figure 3As shown, in one implementation, the connecting frame 6 includes a fixed bracket 601 and a movable bracket 602. The fixed bracket 601 is installed on the mounting frame 2, and the movable bracket 602 is rotatably installed inside the fixed bracket 601. The movable bracket 602 is connected to the bladeless wind turbine 5 and the generator shaft 3. Under the action of the bladeless wind turbine 5, the movable bracket 602 rotates relative to the fixed bracket 601, thereby driving the generator shaft 3 to rotate.

[0042] One end of the torsion spring 7 is connected to the mounting bracket 2 via a fixed bracket 601, and the other end of the torsion spring 7 is connected to the generator shaft 3 via a movable bracket 602. The bladeless wind turbine 5 and the generator shaft 3 are connected via a connecting bracket 6.

[0043] like Figure 3 As shown, in one implementation, the fixed bracket 601 includes multiple connecting sleeves 6011 and multiple partitions 6012. The multiple connecting sleeves 6011 are parallel to each other, and the axis of the connecting sleeves 6011 is parallel to the height direction of the base 1. Multiple partitions 6012 are perpendicular to the height direction of the base 1, and multiple partitions 6012 are connected to the connecting sleeve 6011 along the height direction of the base 1. There is an installation gap between adjacent partitions 6012. The torsion spring 7 is located in the installation gap, and at least a portion of the movable bracket 602 is directly opposite the installation space, thereby facilitating the connection between the torsion spring 7 and the movable bracket 602.

[0044] The fixed bracket 601 facilitates the connection between the torsion spring 7 and the mounting bracket 2, thereby improving the ease of installation of the torsion spring 7.

[0045] like Figure 3 As shown, in one implementation, the movable support 602 includes a connecting column 6021 and multiple isolation plates 6022. The axis of the connecting column 6021 is parallel to the height direction of the base 1, and the connecting column 6021 is arranged through multiple partitions 6012.

[0046] Specifically, a through hole is formed in the middle of the partition 6012, and the connecting post 6021 is located in the through hole.

[0047] Multiple isolation discs 6022 are evenly connected to the connecting column 6021 along the height direction of the base 1, and the multiple isolation discs 6022 are located in different installation gaps. The end of the torsion spring 7 is connected to the isolation disc 6022, thereby realizing the connection between the torsion spring 7 and the movable bracket 602 and improving the installation convenience of the torsion spring 7.

[0048] It should be noted that in this implementation, one isolation disk 6022 is adapted within each installation gap.

[0049] Multiple isolation panels 6022 are connected to the generator shaft 3 respectively.

[0050] like Figure 4As shown, in one implementation, the power generation shaft 3 includes multiple shaft units 301, which are respectively connected to the isolation disk 6022.

[0051] Specifically, the isolation disk 6022 has multiple shaft holes, and multiple rotating shaft units 301 are respectively inserted into the multiple shaft holes to facilitate the connection of the power generation rotating shaft 3 to the isolation disk 6022.

[0052] It should be noted that the through hole of the partition 6012 is larger than the maximum diameter of the generator shaft 3. Optionally, the generator shaft 3 is fitted with a bearing, so that the generator shaft 3 is connected to the through hole of the partition 6012 through the bearing, allowing the generator shaft 3 to rotate relative to the fixed bracket 601.

[0053] like Figure 3 and Figure 4 As shown, as one implementation, connecting brackets 6 are installed at both ends of the rotating shaft unit 301 along the height direction of the base 1, so that the rotating shaft unit 301 can be stably installed in the mounting bracket 2.

[0054] The power generation shaft 3 also includes a first main shaft 302 and a second main shaft 303. Along the height direction of the base 1, the first main shaft 302 and the second main shaft 303 are respectively connected to the two ends of the shaft unit 301. The end of the first main shaft 302 away from the shaft unit 301 is connected to the first end plate 201 of the mounting bracket 2, and the end of the second main shaft 303 away from the shaft unit 301 is connected to the power generation component 4.

[0055] The first spindle 302 is connected to the first end plate 201, which improves the ease of installation of the power generation shaft 3 and the mounting bracket 2. The second spindle 303 is connected to the power generation component 4, which also improves the ease of installation of the power generation shaft 3 and the power generation component 4.

[0056] It should be noted that the outer walls of the first spindle 302 and the second spindle 303 abut against the outer walls of the multiple rotating shaft units 301, thereby facilitating the fixed connection of the first spindle 302 and the second spindle 303 to the rotating shaft unit 301 by means of welding or other methods.

[0057] like Figure 3 As shown, in one implementation, the movable bracket 602 also includes a connecting rod 6023 and a connecting ring 6024. One end of the connecting rod 6023 is connected to the isolation plate 6022, and the other end of the connecting rod 6023 extends to the outside of the mounting bracket 2. The connecting rod 6023 is connected to the connecting ring 6024, and the movable bracket 602 is connected to the bladeless impeller 5 through the connecting ring 6024.

[0058] It should be noted that during the rotation of the movable support 602, the column 203 will limit the swing angle of the connecting rod 6023, thereby limiting the rotation angle of the movable support 602, so that the generator shaft 3 reciprocates within a certain angle range, thereby reducing the rotation speed of the generator shaft 3 and improving the service life of the generator equipment.

[0059] like Figure 2 As shown, in one implementation, the bladeless impeller 5 includes a wind duct 501 and a connecting cylinder 502. The connecting cylinder 502 is installed inside the wind duct 501, and the connecting ring 6024 is fixed to the inner side of the connecting cylinder 502.

[0060] Multiple air ducts 5011 are formed on the air duct 501. The air ducts 5011 are inclined relative to the diameter of the air duct 501 so that the bladeless wind turbine 5 can be driven to rotate under the action of external wind force, thereby facilitating the rotation of the power generation shaft 3 and enabling the power generation component 4 to generate electricity.

[0061] It should be noted that the connecting tube 502 only serves to connect the air duct 501 to the movable support 602, and the connecting tube 502 will not cause significant interference to the airflow passing through the air duct 501.

[0062] like Figure 1 As shown, in one implementation, the base 1 includes a mounting column 102 and an equipment platform 103. Along the height direction of the base 1, the mounting column 102 is installed at the bottom of the equipment platform 103, and the equipment platform 103 is installed above the sea level by means of the mounting column 102. The mounting bracket 2 is installed at the top of the equipment platform 103.

[0063] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.

[0064] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by the appended claims.
