Description

Technical Field

[0001] This utility model relates to the field of spiral turbine generators, specifically a spiral turbine generator for wind power generation. Background Technology

[0002] Spiral turbine generators are a type of small wind power generation device widely used in homes in areas with abundant wind resources. They can make full use of local scattered and continuous wind resources to convert wind energy into electrical energy, providing a partial supplement to household electricity consumption. Because they are easy to install and have few restrictions on the site, they are very suitable for placement around residential areas, helping families achieve a certain degree of energy self-sufficiency. Therefore, they are very popular among residents in areas with excellent wind conditions.

[0003] A typical wind turbine generator consists of rose-shaped wind turbine blades, a rotor, bearings, a generator unit, and a support frame. When natural wind acts on the rose-shaped wind turbine blades, the blades rotate under the force of the wind, which in turn drives the rotor, which is fixedly connected to the blades, to rotate synchronously. The rotation of the rotor then drives the rotor inside the generator unit to rotate relative to the stator. By using the principle of electromagnetic induction, the mechanical energy of the rotating blades is converted into electrical energy, and finally, electricity is output that can be used by residents, thus completing the conversion of wind energy into electrical energy.

[0004] In practical applications of existing spiral turbine generators, the rotor with the spiral turbine blades is fixedly welded on, and bearings are usually installed at both ends. The rotor is then securely mounted on the support frame with six sets of bolts. However, when the rotor is damaged due to long-term stress, material fatigue, or external impact and needs to be replaced, personnel have to tediously disassemble multiple sets of fixing bolts, adjust the bearings and other related components, and after replacing the rotor, they have to reinstall and tighten the bolts precisely. This makes the entire operation process complicated, increases the workload of maintenance personnel, and reduces the efficiency of equipment maintenance and repair. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a spiral turbine generator for wind power generation to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spiral turbine generator for wind power generation, comprising a fixed frame, a first rotating column and a second rotating column respectively arranged on the top two sides of the fixed frame, a cross hole opened inside the first rotating column, a generator connected to one end of the first rotating column, a fixed column sleeved on the outer wall of the second rotating column, four sets of springs installed on one side of the fixed column, a fixed rod arranged on one side of the fixed column, a knob installed at one end of the fixed rod, an insertion hole opened inside the second rotating column, a rotating rod arranged inside the insertion hole, multiple sets of turbine blades fixed on the outer wall of the rotating rod, and a base installed at the bottom of the fixed frame.

[0007] By adopting the above technical solution, the problem of cumbersome disassembly and replacement of rotating rods with welded helical turbine blades is solved. When the rotating rod needs to be replaced, the operator rotates the anti-slip plate to one side, allowing the operator to move the fixing rod by rotating the knob. Then, the operator can push the fixing post into the fixing frame, providing space for one end of the rotating rod to be pulled out from inside the first rotating post, thus removing the rotating rod. Before the operator inserts one side of the new rotating rod into the first rotating post, the fixing post is pushed into the fixing frame. When the fixing post is released, the spring compressed on one side of the fixing post pushes the fixing post towards the rotating rod, allowing the rotating rod to be inserted into the second rotating post. Finally, the operator manually rotates the knob, causing the fixing post to press and push the fixing post towards the rotating rod, so that one end of the rotating rod is fully inserted into the fixing post. This method speeds up the disassembly and installation of the rotating rod.

[0008] The present invention is further configured such that one end of the rotating rod is cylindrical and the other end is cross-shaped.

[0009] Preferably, one end of the rotating rod is cross-shaped and snap-fitted to the first rotating column. When the rotating rod rotates, it can drive the first rotating column to rotate. The cylindrical end of the rotating rod is tightly fitted to the inner wall of the second rotating column.

[0010] The present invention is further configured such that a limit block is fixed at the top of the fixed column, and a sliding groove is provided inside the fixed frame.

[0011] Preferably, the fixing frame controls the sliding distance of the fixing column by a limiting block, and the limiting block prevents the fixing column from rotating.

[0012] The present invention is further configured such that the gap length of the groove is equal to the total length of the cross hole and the insertion hole.

[0013] Preferably, when the fixed column is fully moved into the fixed frame, the two ends of the rotating rod separate from the first and second rotating columns, thereby allowing personnel to remove the rotating rod from the fixed frame.

[0014] The present invention is further configured such that the fixing rod and the fixing frame are connected by a thread.

[0015] Preferably, when the fixing rod rotates, the fixing rod can push the fixing post in the direction of the rotating rod, so that the cylindrical end of the rotating rod is fully inserted into the socket.

[0016] The present invention is further configured such that one end of the fixing rod has a T-shaped cross-section, and the end diameter of the fixing rod is larger than the outer wall diameter of the fixing rod.

[0017] Preferably, the T-shaped end of the fixing rod increases the contact area between the fixing rod and the fixing post, so that the fixing rod can hold the fixing post in place and will not move.

[0018] The present invention is further configured such that an anti-slip plate is provided on one side of the knob, and a connecting post is connected to the end of the anti-slip plate.

[0019] Preferably, the anti-slip plate fits tightly against the wall of the knob, and the anti-slip plate blocks the knob so that the knob will not rotate outward due to the vibration of the fixing frame.

[0020] The present invention is further configured such that one end of the connecting column has a T-shaped cross-section, and one end of the connecting column is located inside the fixing frame.

[0021] Preferably, one end of the connecting column is movably disposed inside the fixed frame, and the anti-slip plate can be manually rotated by a person so that the anti-slip plate can contact and separate from the knob.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model solves the problem of cumbersome disassembly and replacement of rotating rods with welded helical turbine blades by setting up a fixed frame, rotating rod, first rotating column, second rotating column, fixed column, spring, fixed rod, and knob. When the rotating rod needs to be replaced, the operator rotates the anti-slip plate to one side, allowing the operator to move the fixed rod by rotating the knob. Then, the operator can push the fixed column into the fixed frame to provide space for one end of the rotating rod to be pulled out from inside the first rotating column, thus removing the rotating rod. Before the operator inserts one side of the new rotating rod into the first rotating column, the fixed column is pushed into the fixed frame. When the fixed column is released, the spring compressed on one side of the fixed column pushes the fixed column towards the rotating rod, so that the rotating rod is inserted into the second rotating column. Finally, the operator manually rotates the knob, causing the fixed rod to squeeze and push the fixed column towards the rotating rod, so that one end of the rotating rod is fully inserted into the fixed column. This method speeds up the disassembly and installation of the rotating rod.

[0024] 2. This utility model, by setting up a protective plate, connecting column, knob and fixing rod, will cause the rotating rod to vibrate due to the high speed rotation of the turbine blades when the wind force is too strong. Since the fixing rod and the fixing frame are connected by threads, the vibration of the rotating rod will cause the fixing frame to vibrate as a whole, which will cause the fixing rod to slide slowly outward. The anti-slip plate that contacts the knob wall surface installed at the end of the fixing rod will squeeze and limit the knob, preventing the fixing rod from driving the knob to move outward.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] Please see Figure 1 — Figure 5The system includes a mounting frame 1, with a first rotating column 3 and a second rotating column 401 respectively located on the top two sides of the mounting frame 1. The first rotating column 3 has a cross-shaped hole 301 inside, and a generator 302 is connected to one end of the first rotating column 3. A fixing column 4 is fitted onto the outer wall of the second rotating column 401. Four sets of springs 405 are installed on one side of the fixing column 4, and a fixing rod 5 is located on one side of the fixing column 4. A knob 501 is installed at one end of the fixing rod 5. An insertion hole 402 is opened inside the second rotating column 401, and a rotating rod 2 is installed inside the insertion hole 402. Multiple sets of turbine blades 201 are fixed to the outer wall of the rotating rod 2. A base 101 is installed at the bottom of the mounting frame 1. This system solves the problem of cumbersome disassembly and replacement of the rotating rod with welded helical turbine blades. When the rotating rod 2 needs to be replaced... The operator rotates the anti-slip plate 6 to one side, allowing the operator to move the fixed rod 5 by rotating the knob 501. Then, the operator can push the fixed post 4 into the fixed frame 1, providing space for one end of the rotating rod 2 to be pulled out from inside the first rotating post 3, thus removing the rotating rod 2. Before the operator inserts one side of the new rotating rod 2 into the first rotating post 3, the operator pushes the fixed post 4 into the fixed frame 1. When the fixed post 4 is released, the spring 405 compressed on one side of the fixed post 4 pushes the fixed post 4 towards the rotating rod 2, so that the rotating rod 2 is inserted into the second rotating post 401. Finally, the operator manually rotates the knob 501, causing the fixed rod 5 to press and push the fixed post 4 towards the rotating rod 2, so that one end of the rotating rod 2 is fully inserted into the fixed post 4. This method speeds up the disassembly and installation of the rotating rod 2.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 , Figure 3 and Figure 4 One end of the rotating rod 2 is cylindrical, and the other end is cross-shaped. The cross-shaped end of the rotating rod 2 is snapped together with the first rotating column 3. When the rotating rod 2 rotates, it can drive the first rotating column 3 to rotate. The cylindrical end of the rotating rod 2 is tightly fitted with the inner wall of the second rotating column 401.

[0036] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 A limiting block 403 is fixed to the top of the fixed column 4, and a sliding groove 404 is provided inside the fixed frame 1. The fixed frame 1 controls the sliding distance of the fixed column 4 through the limiting block 403, and the setting of the limiting block 403 prevents the fixed column 4 from rotating.

[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 , Figure 3 and Figure 4The gap length of the slide 404 is equal to the total length of the cross hole 301 and the insertion hole 402. When the fixed column 4 is completely moved into the fixed frame 1, the two ends of the rotating rod 2 are separated from the first rotating column 3 and the second rotating column 401, so that the personnel can remove the rotating rod 2 from the fixed frame 1.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The fixing rod 5 and the fixing frame 1 are connected by threads. When the fixing rod 5 rotates, the fixing rod 5 can push the fixing post 4 towards the rotating rod 2, so that the cylindrical end of the rotating rod 2 is fully inserted into the insertion hole 402.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 One end of the fixing rod 5 has a T-shaped cross section, and the diameter of the end of the fixing rod 5 is larger than the diameter of the outer wall of the fixing rod 5. The T-shaped end of the fixing rod 5 increases the contact area between the fixing rod 5 and the fixing post 4, so that the fixing rod 5 can hold the fixing post 4 and will not move.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 and Figure 4 A sliding plate 6 is provided on one side of the knob 501. A connecting post 601 is connected to the end of the sliding plate 6. The sliding plate 6 is tightly fitted to the wall of the knob 501. The sliding plate 6 blocks the knob 501, so that the knob 501 will not rotate the fixing rod 5 outward due to the vibration of the fixing frame 1.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 One end of the connecting post 601 has a T-shaped cross section and is located inside the fixed frame 1. The connecting post 601 is movably located inside the fixed frame 1, and personnel can manually rotate the anti-slip plate 6 so that the anti-slip plate 6 can contact and separate from the knob 501.

[0042] In practical operation, when the rotating rod 2 needs to be replaced, the operator first manually rotates the anti-slip plate 6. The anti-slip plate 6 rotates around the connecting post 601. When the anti-slip plate 6 separates from the knob 501, the operator manually rotates the knob 501. The rotating knob 501 causes the fixed rod 5, which is fixedly connected to its end, to rotate. Because the fixed rod 5 is internally threaded to the fixing frame 1, one end of the fixed rod 5 rotates and moves away from the fixing post 4 until the T-shaped end wall of the fixed rod 5 is in contact with the wall. The inner wall of the fixing frame 1 is in contact. Then, the operator pushes the fixing post 4 towards the knob 501, moving the fixing post 4 into the interior of the fixing frame 1. The second rotating post 401 inside the fixing post 4 separates from one end of the rotating rod 2. Subsequently, the operator removes the cross-shaped end of the rotating rod 2 from the cross hole 301 of the first rotating post 3. Before installing the new rotating rod 2 onto the fixing frame 1, the operator first pushes the fixing post 4 into the interior of the fixing frame 1, causing the fixing post 4 to move into the interior of the fixing frame 1. When the fixing post 4 moves, the fixing post 4 presses against the wall. Contract the spring 405, and then the operator inserts the cross-shaped end of the new rotating rod 2 into the cross hole 301 of the first rotating column 3. Then, slowly release the fixing column 4. The compressed spring 405 pushes the fixing column 4 outwards. During the movement of the fixing column 4, the operator aligns the other end of the rotating rod 2 with the insertion hole 402 of the second rotating column 401, so that the end of the rotating rod 2 is inserted into the insertion hole 402 inside the second rotating column 401. Then, the operator rotates the knob 501, causing the knob 501 to drive the fixing rod. 5. Rotate and move towards the fixed column 4. When the end wall of the fixed rod 5 contacts the side wall of the fixed column 4, the operator continues to rotate the knob 501, so that the fixed rod 5 pushes the fixed column 4 outward, so that one end of the rotating rod 2 is fully inserted into the insertion hole 402 inside the second rotating column 401, until the knob 501 contacts the wall of the fixed frame 1. At this time, the limiting block 403 at the top of the fixed column 4 is displaced to the end of the slide groove 404. Finally, the operator manually rotates the anti-slip plate 6 so that the inner wall of the anti-slip plate 6 fits against the wall of the knob 501.
