Description

Technical Field

[0001] The present invention relates to the technical field of metal processing, and more specifically, to a wind turbine tower reinforcement device. Background Art

[0002] The wind turbine tower is the tower of the wind turbine, which mainly plays a supporting role in the wind turbine generator set. As an important part of the construction of a wind farm, the wind turbine tower is not only related to the safe and reliable operation of the wind farm, but also affects the return on investment of the wind farm.

[0003] The installation process of the existing wind turbine tower reinforcement device is relatively complicated, and most of them are fixed with a large number of bolts, which not only has high operating intensity but also affects the construction efficiency.

[0004] After searching, a Chinese patent with announcement number CN217712815U discloses a novel wind turbine tower reinforcement device. The invention enables the movable plate to move downward through the cooperation of the first bevel gear and the second bevel gear. The movable plate drives the annular plate and the support rod to move downward and allows the insertion rod to be inserted into the inside of the insertion ring, so that the reinforcement tube can be tightened and fixed to the top of the base. The reinforcement tube can be fixed to the top of the base without using bolts, thereby ensuring that the tower is firmly inserted into the inside of the reinforcement tube, thereby improving the stability of the tower.

[0005] However, when the above-mentioned tower reinforcement device is actually used, after the tower body and the base are bolted, the bolts will become loose after long-term use. If they are not checked and tightened in time, the screws may become loose, which may cause the risk of the tower body shaking. Summary of the invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a wind turbine tower reinforcement device to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A wind turbine tower reinforcement device comprises two towers and a base, the towers are vertically placed on the top of the base, the outside of the base is fixedly connected with a plurality of connecting columns, the upper and lower ends of the towers are welded with connecting flanges, and the connecting flanges of the two tower connecting ends are plugged with a plurality of bolts 1, a strengthening and stabilizing mechanism is arranged on the top of the base, and an auxiliary fastening mechanism is arranged on the outside of the tower, the strengthening and stabilizing mechanism comprises a bottom plate, the lower surface of the bottom plate is fixedly connected to the outside of the base, the top of the bottom plate is fixedly connected with a plurality of bolts 2, the outside of the bottom plate is fixedly connected with a plurality of fixing frames, a slider is slidably connected inside the fixing frame, a latch is plugged on the outside of the slider, and the latch passes through the inside of the slider and is clamped with the bottom of the bottom of the base, one side of the slider is fixedly connected with a limiting block, and one side of the limiting block is clamped with the outside of the bolt 2, the tower and the inside of the base are both fixedly connected with a plurality of clamping columns, the bottoms of the two towers are both fixedly connected with lower plug pipes, the outside of the lower plug pipes are provided with a plurality of clamping grooves, and the inner sides of the clamping grooves are clamped with the clamping columns.

[0009] By adopting the above technical solution: different towers and bases are vertically distributed in sequence, and a pair of different towers are connected through corresponding connecting flanges and bolts. By strengthening the stabilizing mechanism, the connection between the tower and the base can be further limited to reduce the loosening of the screws after long-term use. At the same time, whether the screws are tightened in place can also be observed by whether the limit block can smoothly limit one side of the nut. At the same time, the different towers and bases can be further limited through the inner lower insert pipe, so that the connection between different towers and bases is strengthened.

[0010] As a further description of the above technical solution: the auxiliary fastening mechanism includes a guide ring, the inner side of the guide ring is fixedly connected to the outer side of the tower, the outer side of the guide ring is slidably connected to two push blocks, the bottoms of the two push blocks are fixedly connected to a bottom ring, the outer side of the push blocks is clamped with a bracket, the outer side of the bracket is threaded with two screws, the top of the bracket is hinged with a placement ring, and the two placement rings are symmetrically arranged on the outer side of the bottom ring.

[0011] By adopting the above technical solution: during the process of screw tightening, the fastening nuts between the tower and the base can be guided by two corresponding push blocks and placement rings, so that the nuts can be tightened in opposite directions, so that bolt one and bolt two can exert sufficient tightening force.

[0012] Technical effects and advantages of the present invention:

[0013] 1. By setting up a strengthening and stabilizing mechanism, compared with the prior art, the connection between different towers and bases can be further limited, and the nuts after tightening can be further limited, which can prevent the bolt 2 from loosening after tightening, and improve the stability of the installation and use of the wind turbine tower;

[0014] 2. By setting up an auxiliary fastening mechanism, compared with the prior art, construction workers can be guided to a certain extent and the bolts can be fastened in opposite directions, so that the bolts can provide better fastening, ensuring that the bolts are evenly stressed during the connection process, which helps to enhance the integrity of the wind turbine tower structure.
