Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a stable bracket for wind power generation. Background Art

[0002] Converting the kinetic energy of wind into mechanical energy, and then converting the mechanical energy into electrical energy, this is wind power generation. Wind power generation generally uses a tower to support the rotating blades. Wind power generation equipment is generally installed in open areas or on top of a mountain. In order to ensure that the tower can stably support the rotating blades and other devices, a bracket will be set under the tower to make the tower more stable.

[0003] However, the prior art still has the following defects:

[0004] Generally, screws are used to fix the tower body to the ground, and then a clamping ring is connected to the outside of the tower body through bolts. A support rod is provided on the outside of the clamping ring, and the other end of the support rod is bolted to the ground to form a triangular structure to support the tower body. However, the tower body is generally wide at the bottom and narrow at the top, and the inside of the clamping ring is generally flat and cannot fit the curved surface. If the outside of the tower body is specially customized, the cost will be relatively high. Utility Model Content

[0005] In order to solve the technical problem that when a clamp ring is installed on the outside of a tower body, the inside of the clamp ring cannot fit tightly with the outside of the tower body, and the tower body support is not very stable, the utility model provides a stable bracket for wind power generation.

[0006] The utility model adopts the following technical scheme to achieve: a stable bracket for wind power generation.

[0008] Through the above technical solution, the arc plate can be more stable when it is installed with the tower body under the action of the insertion mechanism, and the gap in the middle will be filled with rubber blocks. Similar to the mortise and tenon structure, the material of the rubber block has a slight elasticity, so that when the arc plate moves downward, it will slightly squeeze the rubber block and then completely enter and clamp it between the arc plate and the tower body. The position of the screws and the clamping plate can be reinforced under the action of the fixing mechanism, making the installation of multiple support rods more stable.

[0009] As a further improvement of the above solution, a protective plate is provided above the chassis in the gap where the screws contact each other, and grooves for tightening the screws are provided on both sides of the protective plate.

[0010] Through the above technical solution, the provision of the protective plate can ensure that the wear between the screws and the chassis is not very good, thereby extending the service life of the chassis.

[0011] As a further improvement of the above scheme, the insertion unit includes a guide block, a card plate, a second screw groove, a support rod, an arc plate, a rubber block, a slider, a movable block, a support rod, a pressing plate and a separation unit. The card plate is provided with a second screw groove on both sides, and the second screw groove can be passed through by the screw rod. The bottom of the card plate contacts the screw, one end of the support rod is hinged on the card plate, and the other end of the support rod is hinged on the arc plate. The three arc plates are installed and connected by bolts, the rubber block is glued to the outside of the tower body and is located below the arc plate, the guide block is fixed to the bottom of the second groove and the two ends of the screw are located in the protruding groove.

[0012] Through the above technical solution, the two hinged rods can be guided under the action of the guide block, so that the two hinged rods can enter the extension groove along the outside of the guide block and then enter the soil for reinforcement, and under the action of screw groove one and screw groove two, the screw rod can fix the clamping plate and the screw, thereby enhancing stability.

[0013] As a further improvement of the above scheme, one ends of the two hinged rods are inserted through the extension groove and inserted into the soil around the screw, and the two extension grooves are opened on both sides of groove two and are located below the screw, and the other ends of the two hinged rods are hinged on the slider, and a slide rail for the slider to slide is opened below the movable block, and the slider slides on the slide rail, and the other end of the movable block is connected to one end of the support rod, and the other end of the support rod is connected to one end of the pressing plate, and both ends of the pressing plate are provided with grooves for the screw to pass through.

[0014] Through the above technical solution, the two hinged rods are placed into the second groove by picking up the pressing plate and moving downward along the second groove, which can save labor and strengthen the limit between the screw and the soil.

[0015] As a further improvement of the above solution, the separation unit includes a spring 1, both ends of which are welded to the adjacent outsides of the two sliding blocks and are located in a slide rail opened below the movable block.

[0016] Through the above technical solution, the two hinged plugs can be pressed outwards under the action of the movable block, ensuring that the bottoms of the two hinged plugs will contact the two sides of the guide block.

[0017] As a further improvement of the above scheme, the elastic unit includes a limit block, a spring 2 and a mounting block. The mounting block is detachably mounted on the pressing plate, and both ends of the spring 2 are welded to the adjacent side of the two springs 2, and the sides of the two springs 2 that are away from each other are in contact with the screw.

[0018] Through the above technical solution, the screw is installed more stably on the pressing plate, the clamping plate, the screw and the protective plate under the abutment of the two limit blocks, avoiding the screw rotation from being unable to limit the above parts.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] The utility model can make the hinged plug rod enter the ground through the extension groove under the action of the insertion mechanism, so that the connection between the chassis and the ground is more stable, and at the same time, the support rod is driven to move downward, so that the three arc plates also move downward, and the rubber block is squeezed in the gap between the arc plate and the tower body. Under the action of the elastic mechanism, the position of the screw rod can be limited so that it will not rotate easily, thereby ensuring the stability of the three clamping plates installed on the pressing plate.

A protective plate 8 is provided in the gap above the chassis 3 where the screws 5 contact each other, and grooves for tightening the screws 22 are provided on both sides of the protective plate 8. The insertion unit includes a guide block 10, a card plate 11, a screw groove 12, a groove opened on both sides of the pressing plate 21, a screw groove 12, a gong groove 17, and a groove opened on both sides of the protective plate 8, so that 22 can be rotated and fixed thereon, a support rod 13, an arc plate 14, a rubber block 15, a slider 17, a movable block 19, a support rod 20, a pressing plate 21 and a separation unit. The card plate 11 has a screw groove 12 opened on both sides, and the screw groove 12 can be passed through by the screw rod 22, and the bottom of the card plate 11 contacts the screw 5. One end of the support rod 13 is hinged on the card plate 11, and the other end of the support rod 13 is hinged on the arc plate 14. The three arc plates 14 are installed and connected by bolts. The rubber block 15 is glued to the outside of the tower body 1 and is located below the arc plate 14. The guide block 10 is fixed at the bottom of the slot 6 and the two ends of the screw 5 are located in the extended slot 9. One end of the two hinged plug rods 16 passes through the extension slot 9 and is inserted into the soil around the screw 5. The two extension slots 9 are both opened on both sides of the slot 2 6 and are located below the screw 5. The other ends of the two hinged plug rods 16 are hinged on the slider 17. A slide rail is opened below the movable block 19 for the slider 17 to slide. The slider 17 slides on the slide rail, and the other end of the movable block 19 is connected to one end of the support rod 20. The other end of the support rod 20 is connected to one end of the pressing plate 21. Both ends of the pressing plate 21 are opened with slots for the screw 22 to pass through. The separation unit includes a spring 18, and both ends of the spring 18 are welded to the adjacent outsides of the two sliders 17 and are located in the slide rail opened below the movable block 19.

[0031] The implementation principle of a stable support for wind power generation in the embodiment of the present application is as follows: first, place the protective plate 8 on the chassis 3, pick up the screw 5 and align the screw 5 with the slot 1 4, then use a hammer to drive the screw 5 through the middle of the protective plate 8 into the slot 1 4 and then hammer it into the ground, fix the chassis 3 and the protective plate 8, so that the screw 5 fits with the protective plate 8, and the protective plate 8 fits with the chassis 3. Then place the card 11 on the screw 5, pick up the support rod 20, and pass the two hinged plugs 16 through the groove opened in the middle of the card 11, so that the hinged plugs 16 enter the slot 2 6. When the two hinged plugs 16 enter the slot 2 6, the spring 1 18 will be compressed, and the bottom of the two hinged plugs 16 will move downward in line with the slot 2 6. When one end of the two hinged plugs 16 enters the extension slot 9, the two hinged plugs 16 will move away from each other under the rebound effect of the spring 1 18. As the support rod 20 is continuously extended into the groove 2 6, the two hinged rods 16 contact the guide block 10 and slide along the side direction of the guide block 10. At this time, the soil or rock in the extended groove 9 will block the hinged rod 16 from continuing to move downward. At this time, the pressing plate 21 cannot be pressed. The pressing plate 21 is hammered with a hammer so that the pressing plate 21 and the card plate 11 fit together and move onto the screw 5. When the pressing plate 21 continues to approach the screw 5, the two hinged rods 16 will break the soil or rock in the extended groove 9 and continue to move downward, thereby strengthening the connection with the ground. When the pressing plate 21 is attached to the card plate 11 and the card plate 11 is attached to the screw 5, the support rod 13 will be pulled downward, driving the arc plate 14 to move downward, squeezing the rubber block 15 so that the rubber block 15 fills the gap between the arc plate 14 and the tower body 1, and the rubber block 15 is located inside the arc plate 14. Two screws 22 are used to pass through the screw holes, screw groove 21, screw groove 17 and screw holes on both sides of the protective plate 8 on the pressing plate 21, so that the screws 22 can stably limit the connection between the pressing plate 21, the card plate 11, the screw 5 and the protective plate 8. Use a screwdriver to install the mounting block 25 on the pressing plate 21 through the bolts. When installing the mounting block 25, it is necessary to compress the limiting block 23 into the inside of the mounting block 25. After the mounting block 25 is installed, release the limiting block 23 so that the limiting block 23 contacts the top of the screw 22 to limit the screw 22.
