Description

Technical Field

[0001] This utility model relates to the field of wind turbine technology, and in particular to a support structure for a high-power direct-drive wind turbine. Background Technology

[0002] High-power direct-drive fans are a type of fan equipment with high power output. The motor is directly connected to the fan impeller, eliminating the need for transmission devices such as belts and gears to transmit power. They directly and efficiently convert electrical energy into wind energy and are widely used in ventilation, dust removal, and cooling applications in industrial, commercial, and large building applications.

[0003] A search revealed that Chinese Patent CN220015606U discloses a frame for supporting a fan. Addressing the issue that hoisted fans are difficult to position on fixed platforms, and that disassembly and maintenance pose safety hazards to personnel, a large adjustment frame is used. This frame also makes adjusting the fan's rotation angle easier, as it allows for multiple rotations for convenient inspection and maintenance without disassembly.

[0004] While the aforementioned support structure facilitates adjustment of the fan's angle, placing the support frame on the ground increases the risk of collisions if there is significant foot traffic. This can cause the support frame to shift the fan's blowing angle, requiring manual repositioning of the support frame back to its original position, which is inconvenient. Furthermore, if the support frame is knocked over by a collision, it can easily fall to the ground along with the fan, increasing the risk of damage and consequently raising maintenance costs. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a high-power direct-drive fan support structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-power direct-drive fan support structure, comprising two support frames, wherein a locking component is provided in the middle of the support frame;

[0007] The locking assembly includes a mounting bracket, which is fixedly connected to the middle of the support frame. A limiting plate is slidably connected inside the mounting bracket. A screw is fixedly connected to the lower surface of the limiting plate. A connecting rod is fixedly connected to one end of the screw. Both ends of the connecting rod are fixedly connected to a fixing sleeve. A suction cup is provided on the lower surface of the fixing sleeve. Limit grooves are formed on both sides of the inner wall of the fixing sleeve. Limit blocks are slidably connected inside the limit grooves. A piston plate is fixedly connected between two of the limit blocks.

[0008] As a further description of the above technical solution:

[0009] A stud is rotatably connected to the upper surface of the piston plate, and a threaded hole is opened on the upper surface of the fixed sleeve. The stud is threadedly connected to the inside of the threaded hole, and a cross handle is fixedly connected to one end of the stud.

[0010] As a further description of the above technical solution:

[0011] A worm gear is rotatably connected to the middle of the inner wall of the mounting bracket, and a stepper motor is fixedly installed on one side of the mounting bracket. The worm gear has a threaded groove inside, and the worm gear is threaded to the outside of the screw through the threaded groove.

[0012] As a further description of the above technical solution:

[0013] The output end of the stepper motor is fixedly connected to a worm gear, and the worm gear and the worm wheel are meshed together.

[0014] As a further description of the above technical solution:

[0015] One of the support frames has two support rods fixedly connected to one side, and an adjustment component is provided at one end of each support rod. The adjustment component includes an adjustment rod, which is fixedly connected to one end of the support rod. The other support frame has two connecting pipes fixedly connected to one side, and the adjustment rod is slidably connected inside the connecting pipes.

[0016] As a further description of the above technical solution:

[0017] A fixing frame is fixedly connected to the lower surface of the connecting pipe, and multiple fixing posts are slidably connected inside the fixing frame. An arc-shaped plate is fixedly connected to one end of each fixing post, and a locking block is fixedly connected to one side of the arc-shaped plate.

[0020] This utility model has the following beneficial effects:

[0021] 1. By setting a locking component, the worm gear can drive the connecting rod to move down on the fan support frame, thereby driving the connected suction cup to adhere to the ground. During the process of the stud driving the piston plate to move up, the piston plate can easily draw the air inside the suction cup into the fixed sleeve, which enhances the adhesion of the suction cup to the ground. This helps to fix the support frame to the ground through the suction cup, thereby reducing the phenomenon of the support frame and fan tipping over due to human collision.

[0022] 2. By adjusting the components, this utility model utilizes an adjusting rod that slides inside the connecting pipe to facilitate the adjustment of the distance between the two support frames. This helps to adjust the range of support for the fan according to the width and volume of the fan, improving the versatility of the support frame and thus adapting to fans of different widths.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] As attached Figures 1-7 As shown, one embodiment of this utility model is provided: a high-power direct-drive fan support structure, including two support frames 1, with a locking component provided in the middle of the support frame 1;

[0034] The locking assembly includes a mounting bracket 2, which is fixedly connected to the middle of the support frame 1. A limiting plate 3 is slidably connected inside the mounting bracket 2 to limit the screw 4. The screw 4 is fixedly connected to the lower surface of the limiting plate 3. A connecting rod 5 is fixedly connected to one end of the screw 4 to facilitate the movement of the connecting rod 5 driven by the screw 4. Both ends of the connecting rod 5 are fixedly connected to fixing sleeves 6 to facilitate the storage of air inside the suction cup 7. The lower surface of the fixing sleeve 6 is provided with a suction cup 7 for adsorption to the ground. Limiting grooves 8 are opened on both sides of the inner wall of the fixing sleeve 6. Limiting blocks 9 are slidably connected inside the limiting grooves 8. The limiting blocks 9 are made of copper alloy. A piston plate 10 is fixedly connected between the two limiting blocks 9, and the limiting blocks 9 limit the movement of the piston plate 10.

[0035] As attached Figure 3 As shown, a stud 11 is rotatably connected to the upper surface of the piston plate 10, and a threaded hole 12 is provided on the upper surface of the fixing sleeve 6 for installing the stud 11. The stud 11 is threaded into the inside of the threaded hole 12, and a cross handle 13 is fixedly connected to one end of the stud 11 for rotating the stud 11.

[0036] As attached Figure 4 As shown, a worm gear 14 is rotatably connected to the middle of the inner wall of the mounting bracket 2. A stepper motor 15 is fixedly installed on one side of the mounting bracket 2. The worm gear 14 has a threaded groove inside and is threaded to the outside of the screw 4 through the threaded groove. A worm 16 is fixedly connected to the output end of the stepper motor 15. The worm 16 and the worm gear 14 are meshed, which facilitates the rotation of the worm gear 14 by the worm 16, thereby driving the screw 4 to move.

[0037] As attached Figure 2As shown, one of the support frames 1 has two support rods 17 fixedly connected to one side. One end of the support rod 17 is provided with an adjustment component, which includes an adjustment rod 18. The adjustment rod 18 is fixedly connected to one end of the support rod 17. The other support frame 1 has two connecting pipes 19 fixedly connected to one side to accommodate the adjustment rod 18. The adjustment rod 18 is slidably connected inside the connecting pipe 19. A fixing frame 20 is fixedly connected to the lower surface of the connecting pipe 19 to facilitate the installation of the spring 27, the locking block 23, and the fixing post 21.

[0038] As attached Figure 7 As shown, the fixed frame 20 has multiple fixed posts 21 that are slidably connected inside for mounting springs 27, limiting the position of springs 27, and facilitating connection to the arc plate 22. One end of the multiple fixed posts 21 is fixedly connected to the arc plate 22, and one side of the arc plate 22 is fixedly connected to a locking block 23 for locking into the locking groove 26 to fix the adjusting rod 18. The other end of the multiple fixed posts 21 is fixedly connected to a connecting block 24.

[0039] As attached Figure 6 As shown, the lower surface of the adjusting rod 18 has multiple slots 26 for engaging the locking block 23.

[0040] As attached Figure 4 As shown, a pull rope 25 is provided between the two connecting blocks 24 for pulling the two connecting blocks 24 simultaneously with one hand. Multiple springs 27 are fixedly connected to the inner wall of the fixed frame 20. The multiple springs 27 are fixedly connected to the lower surface of the arc plate 22 and play a role in pushing the arc plate 22 with elastic force.

[0041] Working principle: When it is necessary to fix the two support frames 1 on the ground, the output end of the stepper motor 15 is driven by the controller to rotate. The output end drives the worm gear 16 to rotate, which in turn drives the worm wheel 14 to rotate. Under the action of the threaded connection between the worm wheel 14 and the screw 4, the screw 4 is driven to move downward. At this time, the limiting plate 3 will slide inside the mounting frame 2, which makes it easier for the screw 4 to drive the connecting rod 5 to move downward, so that the connecting rod 5 drives the two fixing sleeves 6 and suction cups 7 to stick tightly to the ground. Then, the stepper motor 15 is turned off, and the cross handle 13 is rotated. The cross handle 13 drives the stud 11 to rotate. When the stud 11 rotates on the upper surface of the piston plate 10, under the action of the limiting block 9 sliding inside the limiting groove 8, the piston plate 10 is driven to move upward. This causes the piston plate 10 to draw the air inside the suction cup 7 into the fixing sleeve 6. When the suction cup 7 is firmly attached to the ground, the fixing of the support frame 1 is completed.

[0042] When the support frame 1 is not fixed and the distance between the two support frames 1 needs to be adjusted according to the width of the fan, pull the pull rope 25 so that the pull rope 25 drives the fixed column 21 to slide inside the fixed frame 20 through the connecting block 24. This causes the fixed column 21 to move the arc plate 22 and the locking block 23 down and disengage from the locking groove 26, so that the adjusting rod 18 is released from its limit. Then pull the adjusting rod 18 to slide inside the connecting pipe 19. After adjusting the length of the adjusting rod 18 extending out of the connecting pipe 19, release the pull rope 25. After the multiple springs 27 push the arc plate 22 and then push the locking block 23 into the corresponding groove 26, the fixing of the adjusting rod 18 is completed. Then the fan can be fixed on the support frame 1.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
