Description

Technical Field

[0001] The utility model relates to the technical field of wind power towers, and more specifically to a multi-layer wind power tower supporting device capable of reducing noise. Background Art

[0002] The wind turbine tower is a component of the wind turbine that supports the nacelle and wind rotor. The tower is generally divided into suspension type, simple type and single-rod cable type. Most of the small wind turbines in the 100-watt class adopt the single-rod cable type. The whole tower is mainly composed of three parts: the tower head, the tower body and the tower legs. If it is a guyed iron tower, the guying part is also added. The tower body is the part between the tower legs and the tower frame. The shape of the tower body is mostly a cylindrical hollow body, and its construction cost is relatively low. Since the tower is high and the overall weight is heavy, a stable support base is particularly important at this time.

[0003] There are many existing technologies for supporting devices for wind turbine towers, such as:

[0004] Chinese Patent Publication No. CN218151251U discloses a wind turbine tower stabilizing base, including a stabilizing mechanism, which includes a horizontal plate, a base body, a screw, a driving motor and a spring; both sides of the base body are fixedly connected with horizontal plates, and the top of the horizontal plate is fixedly connected with two vertical plates, and the sides of the two vertical plates close to each other are rotatably connected with screws, and the ends of the two corresponding screws close to each other are welded. The driving motor of the utility model drives the rectangular plate to move and squeeze the connecting rod through the rotation of the screw, and the connecting rod drives the moving plate to move downward through the rectangular block, and the moving plate drives the cylinder to slide on the outside of the positioning rod to stretch the spring, so that the moving plate drives multiple insertion rods to be inserted into the soil, thereby improving the stability of the connection between the base body and the soil at its bottom, and when geological fluctuations occur, it can reduce the impact on the shaking of the base.

[0005] However, when the existing wind turbine tower base is used, the entire base is usually pre-buried with concrete. Under the action of a large load, cracks are easily generated on the concrete surface, which makes the base of the wind turbine tower low in stability. Moreover, although the above-mentioned movable plate drives multiple rods to be inserted into the soil to improve the stability of the connection between the base body and the soil at its bottom, when the tower base and the base body rub against each other, not only noise is generated to affect the surrounding living environment, but also the upper end of the tower body shakes, and the loose soil easily causes the rods to be not firmly fixed in the soil, resulting in reduced stability of the tower body.

[0006] In view of this, the utility model provides a multi-layer wind power tower supporting device which can reduce noise. Utility Model Content

[0007] The purpose of the utility model is to solve the above-mentioned shortcomings and provide a multi-layer wind power tower support device which can improve the stability of the tower body and reduce noise.

Secondly, the tower body is in contact with the rubber pad. When the tower body shakes, the tower body rubs against the rubber pad, which can reduce the noise generated by the direct friction between the tower body and the rigid parts and reduce the impact on the surrounding living environment.

[0009] Therefore, the utility model provides a multi-layer wind power tower support device that can reduce noise, including a support base, wherein a bottom plate for fixing the tower body is provided in the middle of the support base, and a group of first stabilizing devices are provided in the grooves opened at the four corners of the support base, one end of the first stabilizing device is attached to a stabilizing rod, a stabilizing ring is sleeved on the stabilizing rod, and second stabilizing devices are provided at both symmetrical ends of the stabilizing ring, and the second stabilizing devices are used to control the stability of the tower body.

[0027] However, when the existing wind turbine tower base is used, the entire base is usually pre-buried with concrete. Under the action of a large load, cracks are easily generated on the concrete surface, which makes the base of the wind turbine tower low in stability. Moreover, although the above-mentioned movable plate drives multiple rods to be inserted into the soil to improve the stability of the connection between the base body and the soil at its bottom, when the tower base and the base body rub against each other, not only noise is generated to affect the surrounding living environment, but also the upper end of the tower body shakes, and the loose soil easily causes the rods to be not firmly fixed in the soil, resulting in reduced stability of the tower body.

[0028] like Figure 1-5As shown, the device includes a support base 100, wherein a bottom plate for fixing the tower body is provided in the middle of the support base 100, and a group of first stabilizing devices 300 are provided in the grooves opened at the four corners of the support base 100, one end of the first stabilizing device 300 is attached to the stabilizing rod 101, and a stabilizing ring 200 is sleeved on the stabilizing rod 101, and second stabilizing devices 400 are provided at both symmetrical ends of the stabilizing ring 200, and the second stabilizing devices 400 are used to control the stability of the tower body. By arranging the first stabilizing devices 300 at the four corners of the support base 100, and sleeved on the outside of the tower body with a stabilizing ring 200 supported by a plurality of stabilizing rods 101, and at the same time, the second stabilizing devices 400 arranged at both symmetrical ends of the stabilizing ring 200 improve the stability of the tower body, and secondly, the tower body is in contact with the rubber pad 401, and when the tower body shakes, the tower body rubs against the rubber pad 401, which can reduce the noise generated by the direct friction between the tower body and the rigid parts, and reduce the impact on the surrounding living environment.

[0029] Specifically, the first stabilizing device 300 includes a slider 301 and a first spring 302, and two ends of the first spring 302 are fixedly connected to the inner wall of the groove and the slider 301 respectively. The limit blocks 303 provided at both ends of the slider 301 slide in the limit grooves 102 opened on both sides of the groove. When the tower body shakes, the tower body squeezes the rubber pad 401 to one side, so that the rubber pad 401 pushes the second spring 402, the stabilizing ring 200 and the stabilizing rod 101 to move. Then, the stabilizing rod 101 pushes the slider 301 to slide in the groove, and the slider 301 pushes the limit groove 102 to compress the limit groove 102. Since the stabilizing rod 101 and the slider 301 are fixedly connected, under the action of the first springs 302 at the symmetrical ends, the first spring 302 on one side is compressed and the first spring 302 on the other side is stretched, so that the tower body remains stable under the action of the first springs 302 on both sides, preventing the tower body from shaking excessively and affecting the overall stability.

[0030] Secondly, square grooves 201 with the same width as the stabilizing rod 101 are provided at both symmetrical ends of the stabilizing ring 200, and the stabilizing ring 200 and the square groove 201 are slidably connected. Nuts 202 are provided on the stabilizing ring 200 of the outer ring of the square groove 201. The second stabilizing device 400 is composed of a rubber pad 401 and a second spring 402. The second spring 402 is sleeved on a cross bar extending from the end of the rubber pad 401, and the cross bar is sleeved in a screw rod 403. The screw rod 403 is threadedly connected to the nut 202. A plurality of soil blocks for fixing on the soil are provided on the support base 100, and a plurality of circular holes are provided on the stabilizing rod 101. By sleeved the stabilizing ring 200 on the tower body, the screw rod 403 is rotated away from the inner ring of the stabilizing ring 200 according to the use requirements, and the stabilizing ring 200 is pushed to slide on the stabilizing rod 101. When the stabilizing ring 200 moves to a specified height, the screw rod 403 is rotated to make the screw rod 403 extends out to the inner circle of the stabilizing ring 200, and the screw rod 403 passes through the round hole opened in the stabilizing rod 101 to clamp the stabilizing ring 200 on the stabilizing rod 101. Then, the second spring 402 is sleeved on the cross bar at one end of the rubber pad 401, and the cross bar is inserted into the screw rod 403. As the screw rod 403 rotates until the rubber pad 401 contacts the outer surface of the tower body, the extension and contraction of the screw rod 403 is controlled by rotating the screw rod 403 to control the compression degree of the second spring 402. When the tower body shakes, the tower body and the rubber pad 401 contact and rub, reducing the noise generated by friction. At the same time, the second spring 402 is compressed. Under the action of multiple second springs 402, the second spring 402 pushes the screw rod 403 to generate a force on the stabilizing ring 200. The stabilizing ring 200 remains stable under the support of multiple stabilizing rods 101, thereby slowing down the shaking of the tower body and making the tower body more stable.

[0031] In summary, the working principle of this solution is as follows: first, the support base 100 is fixed to the concrete base by multiple bolts, the tower body is fixed to the bottom plate, and the stabilizing ring 200 is put on the tower body. According to the use requirements, the screw rod 403 is rotated away from the inner ring of the stabilizing ring 200, and the stabilizing ring 200 is pushed to slide on the stabilizing rod 101. When the stabilizing ring 200 moves to the specified height, the screw rod 403 is rotated to extend toward the inner ring of the stabilizing ring 200, and the screw rod 403 is extended to the inner ring of the stabilizing ring 200. 03 passes through the round hole in the stabilizing rod 101, and clamps the stabilizing ring 200 on the stabilizing rod 101. Then, the second spring 402 is sleeved on the crossbar at one end of the rubber pad 401, and the crossbar is inserted into the screw rod 403. As the screw rod 403 rotates, until the rubber pad 401 contacts the outer surface of the tower body, the extension and contraction of the screw rod 403 is controlled by rotating the screw rod 403, so as to control the compression degree of the second spring 402. When the tower body shakes, the tower body contacts and rubs against the rubber pad 401. The noise generated during friction is reduced. At the same time, the second spring 402 is compressed. Under the action of multiple second springs 402, the second spring 402 pushes the screw rod 403 to generate a force on the stabilizing ring 200. The stabilizing ring 200 remains stable under the support of multiple stabilizing rods 101, thereby slowing down the shaking of the tower body and making the tower body more stable. Secondly, when the tower body shakes, the tower body squeezes the rubber pad 401 to one side, so that the rubber pad 401 pushes the second spring 402, the stabilizing ring 200 and the stabilizing rod 101 to move, so that the stabilizing rod 101 pushes the slider 301 to slide in the groove, and the slider 301 pushes the limiting groove 102 to compress the limiting groove 102. Since the stabilizing rod 101 and the slider 301 are fixedly connected, therefore, under the action of the first springs 302 at the symmetrical ends, the first spring 302 on one side is compressed and the first spring 302 on the other side is stretched, so that the tower body remains stable under the action of the first springs 302 on both sides, preventing the tower body from shaking excessively and affecting the overall stability.
