[0040] Wind turbines are usually installed horizontally on the tower. Under the dual effects of the gravity and wind load of the long blades, the long blades in operation generally have a large tilt deformation, which is not conducive to the blades capturing wind energy, and may also cause collision accidents with the tower support structure of the wind turbine. In order to efficiently utilize wind energy and improve the energy conversion rate of the wind rotor, most wind turbines are currently designed to install the wind turbine transmission chain on the tower at a certain angle.

[0041] Before a wind turbine is put into operation, it is necessary to perform a rotation test on the transmission chain of the wind turbine to verify the performance reliability of the transmission chain. However, the current test equipment can only test the transmission chain of a single type of wind turbine. When replacing other types of wind turbines, it is necessary to replace the supporting structure to install the corresponding type of wind turbine, which reduces the test efficiency.

[0055] In another embodiment, the first adjusting member 31 and the second adjusting member 32 are both detachably connected to the sliding plate 13, thereby facilitating disassembly and installation, and the output end of the first adjusting member 31 is also slidably connected to the sliding plate, when the first adjusting member 31 adjusts the sliding plate 13 to move, the output end of the second adjusting member 32 slides on the sliding plate 13, and when the second adjusting member 32 adjusts the sliding plate 13 to move, the output end of the first adjusting member 31 slides on the sliding plate 13, thereby avoiding mutual interference; its specific sliding connection structure can be a sliding rod arranged on the sliding plate, and the sliding rod slidably connected to the output end of the first adjusting member 31 is arranged along the second horizontal direction, so that when the sliding plate 13 moves along the second horizontal direction, the output end of the first adjusting member 31 slides on the sliding rod; similarly, the sliding rod slidably connected to the output end of the second adjusting member 32 is arranged along the first horizontal direction, so that when the sliding plate 13 moves along the first horizontal direction, the output end of the second adjusting member 32 slides on the sliding rod.

[0056] In some other embodiments, the adjustment structure can also be two slide rails, which are respectively arranged along the first horizontal direction and the second horizontal direction, one of the slide rails is slidably connected to the other slide rail, and the sliding plate is slidably connected to the upper slide rail, so that the sliding plate can be moved along the first horizontal direction and the second horizontal direction by using the two slide rails.

[0057] In one embodiment, the first adjusting member 31 and the second adjusting member 32 are respectively the first adjusting cylinder and the second adjusting cylinder; a first avoidance space 14 is formed between two frames 12 installed in the same installation space 11, the cylinder body of each first adjusting cylinder is located in the first avoidance space 14, and the output end of the first adjusting cylinder passes through the frame 12 and extends into the frame 12 and is detachably connected to the sliding plate 13; a second avoidance space 15 is formed at a position between the two installation spaces 11 in the base 1, the cylinder body of each second adjusting cylinder is located in the second avoidance space 15, and the output end of the second adjusting cylinder passes through the frame 12 and is detachably connected to the support seat 21 on the sliding plate 13.

[0058] It can be understood that the first adjusting member 31 and the second adjusting member 32 both use cylinders to adjust the position of the sliding plate 13, and a first avoidance space 14 is formed between the two frames 12 in the same installation space 11, which is used to install the cylinder body of the first adjusting cylinder, so that the cylinder body of the first adjusting cylinder is located in the frame 12 without affecting the movement of the sliding plate 13, wherein the cylinder body of the first adjusting cylinder is fixedly installed on the frame 12, and the output end extends into the frame 12 and is connected to the sliding plate 13, and the output end can be retracted relative to the cylinder body to drive the sliding plate 13 to move, and the two first adjusting cylinders in the same installation space 11 are both arranged in the first avoidance space 14, do not occupy additional space, and have high space utilization; at the same time, a second avoidance space 15 is formed between the two installation spaces 11, and the cylinder bodies of the two second adjusting cylinders located at the front end of the base 1 are both located in the second avoidance space 15, also do not occupy additional space, and have high space utilization; and the first adjusting cylinder and the second adjusting cylinder are used to adjust the position of the sliding plate 13, which has a simple structure and saves costs.

[0059] Wherein, each first regulating oil cylinder and each second regulating oil cylinder can adopt the hydraulic cylinder in the prior art.

[0060] In some embodiments, a sealing plate is provided at the top opening of each first avoidance space 14 and each second avoidance space 15 on the base 1 to prevent dust and protect each first adjustment member 31 and each second adjustment member 32 .

[0061] Furthermore, a sliding support seat 16 is provided on the base 1 near the driving mechanism 4. The sliding support seat 16 is slidably connected to the base 1 through a slide rail, and the slide rail extends along the second horizontal direction so that the sliding support seat 16 can move along the second horizontal direction. By setting the sliding support seat 16, it is used to further support the wind turbine 200, and the sliding support seat 16 is movable and can also be adapted to various types of wind turbines, with strong versatility.

[0062] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in one embodiment, in each support assembly 2, the two support seats 21 are respectively a first support seat 21a and a second support seat 21b, wherein the first support seat 21a is arranged close to the driving mechanism 4, the lifting drive member 22 arranged on the first support seat 21a is the first lifting drive member 22a, and the lifting drive member 22 arranged on the second support seat 21b is the second lifting drive member 22b, the support block 23 hinged to the output end of the first lifting drive member 22a is the first support block (23a), and the support block 23 hinged to the output end of the second lifting drive member 22b is the second support block 23b; the position of the wind turbine corresponding to the first support block 23a and the position of the second support block 23b respectively form a first support position and a second support position; the second lifting drive member 22b drives the second support block 23b to rise and fall, so that the wind turbine rotates with the first support position as the fulcrum.

[0063] It can be understood that the first support seat 21a is used to support the front end position of the wind turbine set, and the second support seat 21b is used to support the rear end position of the wind turbine set. When the second lifting drive 22b drives the second support block 23b to rise and fall, the second support position of the wind turbine set rises and falls, and the first support position can maintain its position without moving by connecting with the first lifting drive 22a, so that the entire wind turbine set rotates around the first support position, and because the support plate is hinged to the lifting drive 22, each support plate can also adaptively adjust the angle according to the placement angle of the wind turbine set, which is more conducive to stabilizing and installing the wind turbine set; and the first lifting drive 22a and the second lifting drive 22b cooperate with each other to achieve the adjustment of the height and angle of the entire wind turbine set, so as to quickly and freely switch between multiple angles and positions, and can be widely used in various types of wind turbine transmission chains for rotation tests, with good versatility.

[0064] The first lifting drive member 22a is mainly used to drive simultaneously with the second lifting drive member 22b to adjust the height of the entire wind turbine set. By operating the second lifting drive member 22b alone, the inclination angle of the entire wind turbine set is adjusted.

[0065] In one embodiment, the first lifting drive member 22a is a first lifting cylinder, the cylinder body of the first lifting cylinder is installed on the first support seat 21a, the output end of the first lifting cylinder is connected to the first adapter block 24, and the first adapter block 24 is hinged to the corresponding first support block 23a through a hinge shaft.

[0066] It can be understood that the first lifting drive member 22a is a first lifting cylinder, which has a simple structure, reliable functions, and uses a cylinder to achieve a smoother lifting movement; the cylinder body of the first lifting cylinder is fixed on the support seat 21 to prevent the first lifting cylinder from swinging and causing unstable support. The first adapter block 24 is hinged to the first support block 23a at the output end of the first lifting cylinder, so the structure is simple and easy to disassemble and install.

[0067] In one embodiment, a mounting through hole is provided on the top surface of the mounting seat, a flange is provided on the cylinder body of the first lifting oil cylinder, the cylinder body of the first lifting oil cylinder is penetrated through the mounting through hole, and the flange is matched with bolts to mount the first lifting oil cylinder on the support seat 21.

[0068] Specifically, the first lifting cylinder is arranged along the vertical direction, and the output end of the first lifting cylinder is lifted and lowered along the vertical direction, so the lifting is more stable and the support is more firm.

[0069] In one embodiment, the first adapter block 24 includes a first adapter portion 241 and a first cantilever portion 242 that are connected to each other, the first cantilever portion 242 extends along the second horizontal direction, the first adapter portion 241 is hinged to the first support block 23a through a hinge axis, and the first cantilever portion 242 is detachably connected to the first support seat 21a at both ends along its extension direction through two first connecting rods 25.

[0070] It can be understood that the first adapter portion 241 is located at the top of the first adapter block 24 to provide a more stable supporting force for the first support block 23a. The two ends of the first cantilever portion 242 are also connected to the first support seat 21a through two first connecting rods 25.
