Description

Technical Field

[0002] With the increasing global attention paid to environmental problems brought about by dependence on traditional fossil energy (such as greenhouse gas emissions leading to global warming and air pollution), energy transformation has become an inevitable trend. Wind power generation, as a clean and renewable way to obtain energy, has received widespread attention. Against this background, there is an urgent need for efficient and convenient installation technology for wind turbines. Wind turbine tower technology that is easy to install has emerged to meet the needs of rapid construction of large-scale wind farms.

[0003] Prior art, such as the utility model with publication number CN217206730U, discloses a wind turbine tower that is easy to install. The patent adopts a tower body and a foundation. The bottom of the tower body is fixedly mounted with a base, and a bottom fixing ring is fixedly mounted inside the base. A fixing plate is fixedly mounted on the top of the bottom fixing ring. The top of the tower body is fixedly mounted with a top plate, and the top of the top plate is uniformly provided with top mounting holes. The utility model provides a double fixation when the tower is installed and connected by providing a base and a bottom fixing ring, and a top plate and a top fixing ring. This prevents the installation connection from being twisted and deformed after long-term use, improves the stability of the tower, and provides a protection rod and an anti-fall cone rod to protect people when climbing the tower, preventing people from falling while climbing, increasing the safety of people when climbing the tower, and expanding the scope of application. It solves the problem that existing wind turbine towers do not have a climbing protection function for people, and when people climb inside the tower, they are prone to falling due to slipping, resulting in a low safety factor.

[0004] In the process of installing wind turbine towers in daily life, there is a problem that when installing existing wind turbines, workers are required to insert bolts into threaded holes. Due to a certain error between the threaded holes, when the workers insert the bolts, the bolts are difficult to insert into the threaded holes quickly and accurately, so the workers need to repeat the insertion operation, resulting in low installation efficiency and cumbersome installation operations. Utility Model Content

[0024] See also Figure 1-Figure 7 The utility model provides a technical solution: a wind turbine tower that is easy to install, including a tower body 1, a top fixing ring 2 and an installation component 3. The top fixing ring 2 is installed on the upper surface of the tower body 1, the outer circumference of the tower body 1 is installed with a tower door 4, and the lower surface of the tower body 1 is provided with an installation component 3.

[0025] The cam 314 is provided with a plurality of locking plates 326 which are provided on the top of the cam 314, and a plurality of locking plates 326 are provided on the bottom of the cam 314 to lock the cam 314.

[0026] Specifically, a circular hole is opened on the surface of the mounting base 31 , and a positioning block 39 is slidably connected to the inner wall of the circular hole. The mounting base 31 is arranged in an arc shape.

[0027] The effect achieved by the above components is that the tower body 1 can be subsequently installed by installing the base 31 .

[0028] Specifically, a rotating hole is opened on the surface of the connecting arm 34, and the connecting arm 34 is connected to the linkage frame 33 by rotating about the inner wall of the rotating hole. The connecting arm 34 is connected to the connecting frame 35 by rotating about the inner wall of the rotating hole. Both ends of the connecting arm 34 are arc-shaped. There are two connecting arms 34, and the two connecting arms 34 are symmetrically arranged about the limit block 32.

[0029] The effect achieved by the above components is that the position of the mounting plate 36 can be constrained by the cooperation between the connecting arm 34 and the connecting frame 35, so that the distance between the mounting plate 36 and the limiting block 32 is limited.

[0030] Specifically, the surface of the mounting plate 36 is arranged in an arc shape, and the mounting plate 36 contacts the surface of the mounting base 31 . There are two mounting plates 36 , and the two mounting plates 36 are arranged symmetrically about the limiting block 32 .

[0031] The effect achieved by the above components is that, through the cooperation between the mounting plate 36 and the connecting frame 35 , the mounting base 31 and the threaded hole 37 of the tower body 1 can be directly aligned to facilitate subsequent installation.

[0032] Specifically, the bolts 38 pass through the tower body 1 . There are four bolts 38 , which are arranged diagonally with respect to the mounting plate 36 .

[0033] The effect achieved by the above components is that, through the cooperation between the bolt 38 and the threaded hole 37 , the bolt 38 can be directly screwed into the interior of the mounting base 31 and the tower body 1 , thereby fixing the two.

[0034] Specifically, the card slot 310 is arranged in a C-shape, and there are two card slots 310 . The two card slots 310 are arranged in a left-right symmetrical manner with respect to the positioning block 39 .

[0035] The effect achieved by the above components is: through the cooperation between the clamping groove 310 and the clamping block 314 , the position of the positioning block 39 can be effectively restricted, so that the positioning block 39 can achieve a preliminary restraining effect on the tower body 1 .

[0036] Specifically, the card block 314 is C-shaped, abuts against the card slot 310 , is disposed inside the mounting slot 311 , and is two in number. The two card blocks 314 are symmetrically disposed about the positioning block 39 .

[0037] The effect achieved by the above components is that, through the cooperation between the clamping block 314 and the mounting block 313 , when the positioning block 39 moves inward, the limit spring 312 can be squeezed to limit the position of the positioning block 39 .

[0038] Working principle: When it is necessary to install the tower body 1 and the mounting base 31, the staff picks up the limit block 32 and then inserts the positioning block 39 into the round hole. When the positioning block 39 moves toward the mounting base 31, it moves the clamping block 314 to both ends through the clamping block 314, and then squeezes the limit spring 312. The limit spring 312 is squeezed and deformed, and then drives the mounting block 313 and the clamping block 314 to move into the mounting groove 311. Then the positioning block 39 is inserted into the mounting base 31, and then the limit spring 312 loses pressure and resets, and then the positioning block 39 is preliminarily positioned. After completing the positioning, the staff lifts the tower body 1, aligns it with the mounting base 31, adjusts the position of the tower body 1, makes the clamping groove 310 at the lower end of the tower body 1 align with the positioning block 39, and then places the tower body 1 into the mounting base 31 to achieve preliminary installation. After completing the above operations, the mounting plate 36 is pushed. Under the guidance of the connecting frame 35, the connecting arm 34 and the linkage frame 33, the mounting plate 36 resists the inner arc surface of the mounting base 31, and aligns the bolts 38 installed on its surface with the threaded holes 37 opened on the surfaces of the mounting base 31 and the tower body 1. Then the staff can directly rotate the bolts 38 into the threaded holes 37, and then complete the fixed installation between the mounting base 31 and the tower body 1; by setting up the mounting assembly 3, the positioning block 39 can be inserted into the mounting base 31 first, and then the tower body 1 is preliminarily positioned, and at the same time, the bolts 38 and the threaded holes 37 are positioned, so that when the staff uses the bolts 38, there is no need to find the correct positioning, and the bolts 38 can be directly aligned with the threaded holes 37 to restrict the tower body 1, thereby further improving the efficiency of installation.
