Description

Technical Field

[0001] The utility model relates to the field of wind power generation equipment, in particular to a wind power generation tower protection device. Background Art

[0002] Wind power generation equipment is a kind of equipment that converts wind energy into electrical energy. Currently, wind power towers are the main ones on the market. Wind power towers are generally divided into large wind power towers and small wind power towers. Large wind power towers are mainly installed in relatively open areas, and the tower body and the generator set are fixedly connected. Small wind power towers are generally installed near residential areas, and the tower body and the generator set are rotated.

[0003] At present, small wind power towers are equipped with protective devices to improve their safety during use and the stability of the power tower during use. Generally, a protective device in the form of a support frame is installed at the bottom of the tower pole of the small power tower to improve the stability of the entire tower pole of the small power tower. Because the protective devices are mostly in the shape of a triangular frame, and multiple groups of them are also arranged on the entire tower pole of the small power tower, when in use, the protective devices will improve the overall stability of the small power tower and reduce the probability of violent shaking, thereby extending the service life of the small power tower and reducing the probability of damage during use.

[0004] However, there are still some problems in protecting small power towers by using a single protective device composed of multiple triangular frames. For example, when in use, the connection position between the tower and the top generator set will shake or vibrate to a certain extent due to the blades and long-term rotation. At the same time, the generator set will also rotate and change its angle as the wind direction changes, causing the nut at the connection position between the tower and the top generator set to loosen due to vibration. Once the nut is loose, the force on the screw will increase, and the stability of the generator set will also be reduced. Therefore, the small power tower needs to be inspected and maintained after a period of use. In order to reduce the probability of nut loosening, a wind power tower protective device is proposed to protect the small wind power tower. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0030] The following describes an embodiment of the utility model based on its overall structure.

[0031] Embodiment 1

[0032] A wind power tower protection device, such as Figure 1 one Figure 4 As shown, it includes a mounting plate 1 and a power generation tower body, wherein the power generation tower body is composed of a tower frame 2, a connecting frame 3, a generator set 4, bolts 5 and nuts 6, the tower frame 2 is connected to the generator set 4 through the connecting frame 3, and the tower frame 2 and the connecting frame 3 are connected through bolts 5 and nuts 6;

[0033] Specifically, the mounting plate 1 is slidably mounted on the tower frame 2 of the power tower body, and at the same time, a protective frame 7 slidably connected to the bolts 5 in the power tower body is rotatably mounted on the outer wall of the mounting plate 1. When the mounting plate 1 is fixed in position, the position of the protective frame 7 will be fixed. At this time, the bottom surface of the top end of the protective frame 7 is in contact with the end of the nut 6 in the power tower body, so that the protective frame 7 will limit the top of the nut 6, so that when the nut 6 starts to move upward, it will be blocked by the protective frame 7 until the nut 6 cannot move upward, thereby reducing the probability of the nut 6 becoming loose, effectively improving the stability of the power tower body during use. At the same time, because the protective frame 7 is slidably connected to the bolt 5, the protective frame 7 will also be supported by the bolt 5 at this time, further ensuring that the protective frame 7 can smoothly protect the connection position of the tower frame 2 and the connecting frame 3.

[0034] See also Figure 2 one Figure 4 There are multiple protective frames 7 installed at equal angles on the outer wall of the installation plate 1. The multiple protective frames 7 will limit the corresponding nuts 6, further ensuring the limiting effect on the nuts 6. At the same time, because the cross-section of the protective frames 7 is designed in an inverted L shape, it is further ensured that the protective frames 7 can smoothly block the nuts 6.

[0035] See also Figure 2-Figure 4 A connecting hole 8 corresponding to the bolt 5 is opened at the top of the protective frame 7, so that the top of the protective frame 7 will be slidably connected with the bolt 5 through the connecting hole 8, thereby ensuring that the bolt 5 will cooperate with the connecting hole 8 to restrict the protective frame 7. At the same time, because the end opening corner of the connecting hole 8 close to the nut 6 is designed with an oblique angle, the difficulty of the bolt 5 entering the connecting hole 8 is effectively reduced.

[0036] See also Figure 2-Figure 4 An adjustment mechanism for limiting the mounting plate 1 is provided on the outer wall of the tower 2, and the adjustment mechanism consists of a mounting block 9 and an adjustment groove 10, wherein the mounting block 9 is installed at an equal angle at the bottom end of the mounting plate 1, and an adjustment groove 10 is provided on the outer wall of the tower 2 to be slidably connected with the mounting block 9, so that the mounting block 9 can slide in the adjustment groove 10, and at the same time, the adjustment groove 10 will limit the mounting block 9 to ensure the stability of the mounting plate 1 when sliding;

[0037] Furthermore, when the mounting plate 1 is positioned, the distance between the top of the mounting block 9 and the top of the adjusting slot 10 is greater than the length of the bolt 5 protruding from the nut 6 plus the length of the depth of the connecting hole 8, ensuring that when it is necessary to release the restriction of the protective frame 7 on the nut 6, the mounting block 9 can still slide upward for a distance. In the process of sliding the mounting block 9 upward, the connecting hole 8 is separated from the bolt 5, thereby releasing the restriction of the protective frame 7 and allowing it to rotate.

[0038] See also Figure 2-Figure 4 A positioning mechanism is provided on the mounting plate 1, and the positioning mechanism is used to fix the position of the mounting plate 1. At the same time, the positioning mechanism consists of a self-rotating screw 11 and a threaded hole 12, wherein the self-rotating screw 11 is slidably installed in the mounting block 9, and a threaded hole 12 threadedly connected to the self-rotating screw 11 is provided in the adjustment groove 10, so that when the self-rotating screw 11 enters the threaded hole 12, the position of the mounting block 9 is fixed, thereby ensuring that the position of the mounting plate 1 is fixed, and then ensuring the fixity of the position of the protective frame 7, further ensuring that the protective frame 7 can smoothly fix the position of the nut 6, and the opening position of the threaded hole 12 is designed to be open outward.

[0039] Embodiment 2

[0040] A wind power tower protection device, such as Figure 1-Figure 5 As shown, the technical scheme and parts of this embodiment are basically the same as those of the first embodiment, and the technically identical parts are not repeated here. The difference is that a limiting plate 13 is installed on the outer wall of the middle part of the self-rotating screw 11 in this embodiment, and a sliding groove 14 corresponding to the limiting plate 13 is opened in the mounting block 9 to ensure that the limiting plate 13 can smoothly follow the self-rotating screw 11 to move in the mounting block 9, and after the self-rotating screw 11 is fixed between the threaded hole 12, the distance between the outer wall of the limiting plate 13 and the inner wall of the sliding groove 14 is greater than the depth of the threaded hole 12, so that when the user rotates the self-rotating screw 11 to separate it from the threaded hole 12, the user can clearly feel that the self-rotating screw 11 has been separated from the threaded hole 12, which is convenient for the user to judge whether the self-rotating screw 11 is separated from the threaded hole 12, and at the same time, through the setting of the limiting plate 13 and the sliding groove 14, the self-rotating screw 11 will not be separated from the mounting block 9, preventing the self-rotating screw 11 from slipping out of the mounting block 9, causing the user to need to find the self-rotating screw 11.

[0041] Furthermore, a magnet is installed when the self-rotating screw 11 is embedded inside, and a corresponding magnet is also provided in the threaded hole 12. When the self-rotating screw 11 slides to a state corresponding to the position of the threaded hole 12, the self-rotating screw 11 will slide into the threaded hole 12 under the action of the magnet, thereby facilitating the user to find the position of the threaded hole 12.

[0042] The working principle of the utility model is as follows: when using the device, first push the mounting plate 1 until the top of the mounting block 9 is in contact with the top of the adjusting slot 10, then rotate the protective frame 7, and then pull the mounting plate 1 downward to make the protective frame 7 begin to descend. As the protective frame 7 descends, the bolt 5 will gradually enter the corresponding connecting hole 8 until the protective frame 7 is in contact with the top surface of the nut 6. At this time, the position of the self-rotating screw 11 will correspond to the position of the threaded hole 12, and the self-rotating screw 11 will begin to enter the threaded hole 12 under the action of the screw. Finally, the user twists the self-rotating screw 11 to make it enter the threaded hole 12 to fix the position of the mounting block 9. At this time, the mounting plate 1 will limit the position of the protective frame 7, and the protective frame 7 will fix the position of the nut 6. Because the position of the mounting plate 1 has been fixed, the nut 6 cannot move upward, thereby avoiding the accident of serious loosening of the nut 6, thereby ensuring the protection effect of the protection device on the power tower body.

[0043] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
