Description

Technical Field

[0001] The present invention relates to the technical field of wind turbine blades, and specifically to a spliced - transport - type wind turbine mutual - guide blade. Background Art

[0002] A vertical - type wind turbine is a device that uses wind energy to generate electricity. Its characteristic is that the rotation axis of the wind blade is perpendicular to the ground. This design enables the generator to operate stably under different wind - direction conditions, especially suitable for environments with variable wind directions. A vertical - type wind turbine generally consists of main components such as a base, a mutual - guide component, a guide - frame component, a generator set, a rotating shaft, and a wind blade. The design of the mutual - guide component and the guide - frame component plays a crucial role in the efficiency and stability of the generator. The mutual - guide component can drive the rotating shaft to rotate under the action of wind force through its connection with the guide - frame component, and then drive the generator set to work. The mutual - guide component is hereinafter referred to as the guide - piece component.

[0003] However, the connection method between the conventional guide - piece component and the guide - frame component is relatively simple, only fixed by bolts. This connection method is prone to making the connection between the guide - piece and the guide - frame insecure. After long - term use, the connection part is likely to become loose and fall off under the action of rusting, resulting in a decrease in the service life of the blade. Secondly, the guide - piece component is usually integrally formed, which requires a large space during transportation, is not convenient to fix and install. Therefore, a spliced - transport - type wind turbine mutual - guide blade is needed to solve the existing deficiencies. Summary of the Invention

[0004] Technical Problems to be Solved

[0005] The purpose of the present invention is to make up for the deficiencies of the prior art, and provides a spliced - transport - type wind turbine mutual - guide blade. By setting a limiting component, the integrity of the guide - piece and the limiting shell is further enhanced, reducing the risk of the guide - piece separating from the guide - frame, and making the rotation of the guide - piece more stable; by setting a protection component, the connection precision between the first guide - piece and the sleeve is improved, and under the action of the compression spring, the protection shell always abuts against the inner side of the sleeve; by setting a connection component, through the replacement of the sleeve, the direct scrapping of the entire first guide - piece is avoided, improving the utilization efficiency of the parts of the wind turbine.

Detailed implementation manner

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Such as Figure 1-13As shown in the figure, the present invention provides a technical solution: a spliced and transported wind turbine mutual guide blade, which includes a base 1, a guide blade member and a guide frame member. The guide blade member includes a first guide blade 2 and a second guide blade 3, and the guide frame member includes a first guide frame 4 and a second guide frame 5. The first guide blade 2 and the second guide blade 3 are collectively referred to as the guide blade member. The structures of the first guide blade 2 and the second guide blade 3 are basically the same. Therefore, the description of the structure of the second guide blade 3 is the same as that of the first guide blade 2, that is, the connection method between the first guide blade 2 and the first guide frame 4 is the same as the connection method between the second guide blade 3 and the second guide frame 5. In this embodiment, the number of the first guide blade 2 and the second guide blade 3 is three each, and there are three corresponding positions on the first guide frame 4 and the second guide frame 5 for installing the guide blade member. The top end of the base 1 is fixedly connected with a generator set 6, and the outside of the generator set 6 is fixedly connected with a first guide frame 4. The top end axis of the generator set 6 is fixedly connected with a rotating shaft 7. The outside of the rotating shaft 7 is fixedly connected with a wind blade 8, and the top end of the rotating shaft 7 is movably connected with a second guide frame 5. A plurality of limiting components 9 are arranged on the outside of the first guide frame 4 and the outside of the second guide frame 5. The first guide blade 2 and the second guide blade 3 are both distributed in a circular array. The bottom end of the first guide blade 2 is connected with the first guide frame 4 through the limiting component 9, and the top end of the second guide blade 3 is connected with the second guide frame 5 through the limiting component 9. The top end of the first guide blade 2 is fixedly connected with a protection component 10, the bottom end of the second guide blade 3 is fixedly connected with a connection component 11, and the bottom end of the connection component 11 is fixedly connected with a sleeve 12. The sleeve 12 is movably connected with the outside of the protection component 10. The working principle of this vertical axis wind turbine is briefly described as follows: when the wind force is small, the guide blade member rotates, so that the rotating shaft 7 rotates, thereby driving the generator set 6 to start working; when the wind force is large, the guide blade member becomes an obstacle, and the wind blade 8 rotates and overcomes the obstacle of the guide blade member, so that the generator set 6 starts working.

[0038] As Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the limit component 9 includes a tooth block 901, a rack 902, a connecting block 903, a guide post 904, a positioning rod 905 and a knob 906. A receiving groove is formed at the top end of the second guide piece 3, and the rack 902 is fixedly connected to the inside of the receiving groove. Setting the rack 902 inside the receiving groove is beneficial for inserting the guide piece into the inside of the limit housing 13. Since the cross-section of the guide piece is water-drop shaped, a plane that is in parallel movable contact with the surface of the guide frame is constructed at one end of the guide piece connected to the guide frame. And the tooth block 901 is in one-way movable cooperation with the rack 902. The inclined surface of the tooth block 901 continuously contacts the inclined surface of the rack 902, and the back side of the tooth of the tooth block 901 abuts against the back side of the tooth of the rack 902, so that the rack 902 cannot move back. The tooth block 901 is fixedly connected to one end of the connecting block 903, and the guide post 904 is fixedly connected to the other end of the connecting block 903. The knob 906 is fixedly connected to the tail end of the positioning rod 905, and the front end of the positioning rod 905 abuts against the tail end of the guide post 904. By rotating the position of the positioning rod 905, the moving range of the guide post 904 can be controlled, thereby restricting the moving range of the tooth block 901. If the tooth block 901 abuts against the rack 902 and the tooth block 901 cannot move back, or the tooth block 901 is set to be in movable contact with the rack 902, the tooth block 901 can be briefly separated from the rack 902. The limit component 9 further includes a support frame 907, a return spring 908 and a return rod 909. The support frame 907 is fixedly connected to the inside of the second guide frame 5. A thread is provided on the outside of the positioning rod 905. The positioning rod 905 penetrates through the support frame 907 and is threadedly connected to the support frame 907. One end of the return spring 908 is fixedly connected to the end of the connecting block 903, and the other end of the return spring 908 is fixedly connected to the inside of the support frame 907. The return rod 909 sequentially penetrates through the axis of the positioning rod 905 and the axis of the knob 906, and the front end of the return rod 909 is fixedly connected to the rear end of the guide post 904. A limit housing 13 is fixedly connected to the outside of the second guide frame 5, and the limit housing 13 is in movable cooperation with the top end of the second guide piece 3. Threaded holes are constructed on the limit housing 13, the top of the second guide piece 3 and the end of the second guide frame 5, and the threaded holes are distributed in a triangular shape. The top of the second guide piece 3 is fixedly connected to the limit housing 13 and the second guide frame 5 by bolts cooperating with the threaded holes. The number of threaded holes on the limit housing 13, the second guide piece 3 and the second guide frame 5 is three and they correspond to each other. After the end of the second guide piece 3 is inserted into the inside of the limit housing 13, the threaded holes on the second guide piece 3 automatically align with the threaded holes on the limit housing 13. Guide strips are fixedly connected to both sides inside the limit housing 13, and corresponding guide grooves are provided on the second guide piece 3. The guide strips cooperate with the guide grooves, enabling the second guide piece 3 to quickly cooperate with the inside of the limit housing 13. By the meshing of the tooth block 901 and the rack 902, the length of the end of the second guide piece 3 entering the inside of the limit housing 13 can be flexibly controlled, and at the same time, the length of the end of the first guide piece 2 entering the inside of the limit housing 13 can be flexibly controlled. Through this kind of operation, it is convenient for the first guide piece 2 to be in the correct and appropriate position after being completely inserted into the limit housing 13.And when the second guide piece 3 is completely inserted into the inner part of the limit shell 13 and is in the correct and proper position, it can avoid the situation that after the first guide piece 2 is inserted into the inner part of the limit shell 13, the second guide piece 3 cannot be smoothly inserted into the inner part of the limit shell 13 under the restriction of the first guide piece 2. And the limit shell 13 is sleeved on the outer side of the guide piece, which is beneficial to improving the protection of the end part of the guide piece, avoiding serious rusting at the connection part of the guide frame, guide piece and bolt due to the influence of the external environment. And the limit shell 13 is sleeved on the outer side of the guide piece, further enhancing the integrity of the guide piece and the limit shell 13, reducing the risk of the guide piece separating from the guide frame, making the rotation of the guide piece more stable. In addition, by the way of inserting the guide piece into the inner part of the limit shell 13, it is beneficial to improve the installation efficiency and quality of the guide piece. And when the guide piece is fixed to the guide frame, rotate the positioning rod 905 so that the positioning rod 905 abuts against the guide post 904, making the tooth block 901 and the rack 902 always keep in meshing state, further improving the connection tightness between the guide frame and the guide piece.,

[0039] As Figure 1 、 Figure 9 and Figure 10 shown, the protection component 10 includes a protection shell 1001 and a compression spring 1002. A set of accommodation holes 14 are opened at the top end of the first guide piece 2, and compression springs 1002 are fixedly connected inside the accommodation holes 14. The protection shell 1001 is movably sleeved on the top end of the first guide piece 2, and the top end of the compression spring 1002 is fixedly connected to the inner side of the protection shell 1001. The outer side of the protection shell 1001 is movably matched with the inner side of the sleeve 12. A set of screw holes are opened on the sleeve 12, the end part of the first guide piece 2 and the protection shell 1001. The end part of the first guide piece 2 and the protection shell 1001 are fixedly connected to the sleeve 12 through bolts matching with the screw holes.

[0040] The protection shell 1001 is sleeved on the end part of the first guide piece 2, which is beneficial to improving the protection of the end part of the guide piece. And the protection shell 1001 is movably matched with the sleeve 12, so that the protection shell 1001, the sleeve 12 and the first guide piece 2 are connected by bolts. The setting of the protection shell 1001 can fill the gap generated between the sleeve 12 and the first guide piece 2 due to temperature change, avoiding the occurrence of an activity gap between the sleeve 12 and the end part of the first guide piece 2 due to temperature change, improving the connection precision between the first guide piece 2 and the sleeve 12. And under the action of the compression spring 1002, the protection shell 1001 always abuts against the inner side of the sleeve 12. By the way of the movable cooperation between the sleeve 12 and the protection shell 1001 for splicing the guide pieces, it can be transported in a split package during transportation, greatly reducing the volume of the transportation box body, and can be transported in the same box body as the generator, thereby reducing the transportation cost.

[0041] As Figure 1 、 Figure 11 、 Figure 12 and Figure 13As shown, the connecting component 11 includes inserting blocks 1101, studs 1102, limiting caps 1103, spacers 1104 and connecting columns 1105. The number of inserting blocks 1101 is two, and both inserting blocks 1101 are slightly arc-shaped. The shape of the inserting blocks 1101 matches the shape of the guide piece, facilitating the jacks 15 of the housing 12 to match with the inserting blocks 1101. Moreover, the sizes of the two inserting blocks 1101 are different. The inserting blocks 1101 are fixedly connected to the bottom end of the second guide piece 3. The other ends of the inserting blocks 1101 are fixedly connected with studs 1102, and limiting caps 1103 are threadedly connected to the outer sides of the studs 1102. A connecting column 1105 is fixedly connected to the middle position of the spacer 1104. Two through holes are formed in the spacer 1104, and the spacer 1104 is sleeved on the outer side of the stud 1102 through the through holes. A set of jacks 15 are formed at the end of the housing 12, and the inserting blocks 1101 are respectively adapted to the jacks 15. The connecting component 11 further includes a retaining piece 1106, a receiving cylinder 1107, a compression spring 1108 and a fixing block 1109. The fixing block 1109 is rotatably connected to the retaining piece 1106, and the end of the fixing block 1109 is threadedly connected to the inner side of the connecting column 1105. The number of receiving cylinders 1107 is two, and the receiving cylinders 1107 are fixedly connected to the retaining piece 1106. Compression springs 1108 are fixedly connected to the interiors of the receiving cylinders 1107. The receiving cylinders 1107 are sleeved on the outer sides of the studs 1102 and the limiting caps 1103, and the ends of the compression springs 1108 away from the receiving cylinders 1107 abut against the ends of the studs 1102.

[0042] Align the two jacks 15 at the end of the housing 12 with the insertion blocks 1101 respectively, so as to dock the housing 12 at the bottom end of the second guide piece 3. Then, align the perforations on the spacer 1104 with the studs 1102 respectively, so as to sleeved the spacer 1104 on the outside of the studs 1102, and the spacer 1104 abuts against the inner side of the housing 12. Then, install the limit cap 1103 on the outside of the stud 1102 by screwing the limit cap 1103 with the stud 1102 until the limit cap 1103 abuts against the spacer 1104. Then, align the fixing block 1109 with the inside of the connecting column 1105, and connect the fixing block 1109 with the connecting column 1105 by screwing until the two receiving cylinders 1107 are respectively sleeved on the outside of the limit cap 1103 and the stud 1102, and the end of the compression spring 1108 inside the receiving cylinder 1107 abuts against the end of the stud 1102, so as to fix the housing 12 at the bottom end of the second guide piece 3. Since the housing 12 is sleeved on the outside of the first guide piece 2 and has a protective effect on the first guide piece 2, during the rotation process, the force of the first guide piece 2 on the housing 12 and the wear caused by the change of the external environment to the housing 12 make the housing 12 relatively fragile. Therefore, after long-term use, the housing 12 is prone to damage, such as deformation or severe rusting. Therefore, by replacing the housing 12, the direct scrapping treatment of the entire first guide piece 2 is avoided, and the utilization efficiency of the parts of the wind turbine is improved.

[0043] Working principle: When in use, when installing the guide piece, first splice the first guide piece 2 and the second guide piece 3. Insert the protective shell 1001 at the top of the first guide piece 2 into the inner side of the sleeve 12 until the end of the protective shell 1001 abuts against the innermost end of the sleeve 12, making the compression spring 1002 shorter and completely located inside the receiving hole 14. Then, sequentially penetrate three bolts through the screw holes of the protective shell 1001, the screw holes at the end of the first guide piece 2, and the screw holes of the sleeve, thereby fixing the three together, thus completing the splicing of the first guide piece 2 and the second guide piece 3. Operate in sequence to complete the splicing of the remaining two groups of the first guide piece 2 and the second guide piece 3; The specific operation for replacing the sleeve 12 is as follows. Align the two jacks 15 at the end of the sleeve 12 with the plug blocks 1101 respectively, thereby docking the sleeve 12 at the bottom end of the second guide piece 3. Then, align the through holes on the spacer 1104 with the studs 1102 respectively, thereby sleeving the spacer 1104 outside the studs 1102, and the spacer 1104 abuts against the inner side of the sleeve 12. Then, install the limit cap 1103 to the outside of the stud 1102 by threading the limit cap 1103 with the stud 1102 until the limit cap 1103 abuts against the spacer 1104. Then, align the fixing block 1109 with the inside of the connecting column 1105 and connect the fixing block 1109 with the connecting column 1105 by threading until the two receiving cylinders 1107 are respectively sleeved outside the limit cap 1103 and the stud 1102, and the end of the compression spring 1108 inside the receiving cylinder 1107 abuts against the end of the stud 1102, thereby fixing the sleeve 12 at the bottom end of the second guide piece 3; The specific operation for connecting the first guide piece 2 with the first guide frame 4 and the second guide piece 3 with the second guide frame 5 is as follows. Insert the top end of the second guide piece 3 into the inside of the limit shell 13 until the end of the guide piece abuts against the inner wall of the limit shell 13. During this process, under the action of the return spring 908, the connecting block 903 has a tendency to move away from the return spring 908, making the inclined surface of the tooth block 901 in active contact with the inclined surface of the rack 902, and the rack 902 cannot move in the reverse direction. Only by pulling the return rod 909 outwards, making the tooth block 901, the connecting block 903, and the guide post 904 move away from the rack 902, can the end of the second guide piece 3 be separated from the limit shell 13. Finally, fix the end of the second guide piece 3 on the second guide frame 5 by mating the bolt with the screw hole on the limit shell 13 and the screw hole at the end of the second guide piece 3. Operate in the same way to fix the bottom end of the first guide piece 2 on the first guide frame 4.
