Description

Technical Field

[0001] This utility model relates to the field of wind turbine foundation technology, and in particular to a wind turbine foundation maintenance device. Background Technology

[0002] Wind turbine foundation maintenance devices are specialized equipment components that use automated temperature control, humidity control, and real-time monitoring technologies to perform full-cycle maintenance on wind turbine foundation structures, thereby improving their stability, durability, and reducing operation and maintenance costs.

[0003] Wind turbine foundation maintenance devices generally consist of structures such as moisture-retaining components, auxiliary support components, and heat dissipation components. These devices use sensors to perceive the foundation status in real time, and through PLC intelligent control of temperature control and moisture-retaining modules and remote platform decision-making, they form a closed-loop system of "perception-regulation-monitoring-repair," achieving full-cycle structural maintenance and safety assurance for wind turbine foundations.

[0004] Existing wind turbine foundation maintenance devices cannot quickly connect water pipes without tools, requiring the additional carrying of wrenches and other tools during maintenance. This increases operational steps and preparation time, reducing maintenance efficiency and increasing operation and maintenance costs due to the inconvenience of tool carrying, management, and on-site access. In complex environments such as offshore and mountainous areas, tools are easily affected by weather, leading to connection failures. Furthermore, threaded connections relying on tools are prone to leakage and loosening if improperly operated or subjected to long-term vibration, affecting structural reliability. Therefore, a wind turbine foundation maintenance device is proposed to solve the above problems. Utility Model Content

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

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0032] Reference Figures 1 to 3 One embodiment of this utility model is a fan foundation maintenance device, which includes a frame 1. A water bucket 2 is slidably connected inside the frame 1. The water bucket 2 can slide up and down along the inner wall of the frame 1 to facilitate height adjustment according to maintenance needs. A fixed column 3 is fixedly connected inside the frame 1. The fixed column 3 is vertically set to stably support the subsequent structure. Multiple ball bearings 4 are slidably connected inside the fixed column 3. The ball bearings 4 can roll flexibly inside the fixed column 3 to reduce frictional resistance when the sliding rod 8 is inserted.

[0033] A sliding rod 8 is slidably connected to the outside, and the sliding rod 8 is welded and fixed to the transmission pipe. It can move synchronously with the transmission pipe. Two limiting rings 9 are fixedly connected to the outside. The limiting rings 9 can prevent the sliding rod 8 from sliding out of the fixed column 3. The outer side is slidably connected to the inside of the fixed column 3. The outer side of the ball 4 is slidably connected to the inside of the limiting ring 9. The position of the ball 4 is limited by the limiting ring 9. A compression ring 5 is slidably connected to the outside of the fixed column 3. The compression ring 5 can slide along the outer wall of the fixed column 3. A spring 7 is fixedly connected to the inside. The spring 7 has an elastic reset function. The other end is fixedly connected to the outside of the fixed column 3. A sliding ring 6 is fixedly connected to the outside of the compression ring 5. The sliding ring 6 makes it easy for the operator to push the compression ring 5. Multiple mounting plates 10 are fixedly connected to the outside of the frame 1. The mounting plates 10 are the connection carriers between the frame 1 and the embedded shell 16. The mounting components are slidably connected inside.

[0034] Reference Figure 1 , Figure 2 and Figure 4 The mounting assembly includes a sliding block 11, which can slide back and forth within the mounting plate 10 to mate with the pre-embedded shell 16. A fixing ring 17 is fixedly connected to the outside of the sliding block 11. The bottom of the fixing ring 17 fits against the top of the mounting plate 10, serving to position and stabilize the sliding block 11. The bottom of the fixing ring 17 is slidably connected to the top of the mounting plate 10. The pre-embedded shell 16 is slidably connected to the outside of the sliding block 11. The pre-embedded shell 16 is pre-installed in a designated position to provide embedding space for the sliding block 11. The outside of the pre-embedded shell 16 is slidably connected to the inside of the mounting plate 10. Two pressing rods 12 are slidably connected inside the sliding block 11. The pressing rods 12 can slide towards or away from each other within the sliding block 11. A second spring 13 is fixedly connected to the inside of the sliding block 11. The second spring 13 contracts and stores force when the pressing rods 12 are pressed, and pushes the pressing rods 12 to reset when released.

[0035] Sliding plates 14 are fixedly connected to the outer sides of the two extrusion rods 12. The sliding plates 14 move with the extrusion rods 12 and play the role of transmitting force within the sliding block 11. The outer side is slidably connected to the inside of the sliding block 11. A connecting block 15 is fixedly connected to the end of the sliding plate 14 away from the extrusion rods 12. The connecting block 15 moves with the sliding plate 14 and is used to be fixed by being inserted into the slot of the pre-embedded shell 16. The outer side is slidably connected to the inside of the sliding block 11 and the inside of the pre-embedded shell 16.

[0036] Working principle: When the staff needs to install the frame 1, multiple pre-embedded shells 16 can be pre-installed in the designated positions. Then, the mounting plate 10 connected to the outside of the frame 1 is placed on top of the pre-embedded shell 16. Then, the pressing rod 12 is pressed inward, causing the connecting block 15 to slide into the inside of the sliding block 11. The sliding block 11 is then slid into the inside of the pre-embedded shell 16. After the sliding block 11 can no longer slide inside the pre-embedded shell 16, the pressing rod 12 can be released. The spring 13 inside the pressing rod 12 pushes outward, causing the connecting block 15 to slide again to the outside of the sliding block 11. This allows the connecting block 15 to slide into the slot opened inside the pre-embedded shell 16, thus achieving the effect of fixing the mounting plate 10.

[0037] At this point, the sliding rod 8 can be fixed to the outside of the transmission tube. Then, the sliding ring 6 is pushed inward, which moves the compression ring 5 together. After the ball bearing 4 is no longer restricted by the compression ring 5, the sliding rod 8 can be slid into the inside of the fixed post 3. Then, the sliding ring 6 is released, and the compression ring 5 will be pushed back to its original position by the spring 7. The sliding rod 8 is restricted by the limiting ring 9, thus achieving the effect of installing the transmission tube without tools.

[0038] 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.
