Description

Technical Field

[0001] This utility model relates to the field of generator blade maintenance technology, and more specifically, to a high-altitude operation safety protection platform for wind turbine blade maintenance. Background Technology

[0002] Wind turbine blades are key components of wind turbine generators, responsible for capturing wind energy and converting it into mechanical energy, which is then converted into electrical energy by a generator. During long-term use, wind turbine blades require regular inspection and maintenance to ensure their proper operation.

[0003] Existing platforms for maintaining generator blades primarily rely on steel cables for traction, coupled with a drive unit, guide wheels, and control system to ensure effective transmission of traction force, thereby achieving the platform's ascent and descent. The maintenance platform mainly consists of a frame and guardrails. While the guardrails are designed to ensure operator safety, the height of the guardrails is fixed, leading to several drawbacks. Taller maintenance personnel may find the guardrails too low, resulting in inadequate protection and potential safety hazards when leaning out to operate. Conversely, shorter personnel may find the guardrails too high, making operation inconvenient.

[0004] In view of this, we propose a high-altitude operation safety protection platform for wind turbine blade maintenance. Utility Model Content

[0027] Please see Figure 1-4 This utility model provides a technical solution:

[0028] A high-altitude work safety platform for wind turbine blade maintenance includes a frame 1. Two sets of support frames 2 are fixedly installed on the upper side of the frame 1. Two sets of fixed rods 3 are fixedly installed between the two sets of support frames 2. An adjusting rod 4 is installed on the upper side of the fixed rod 3. A threaded rod 5 is rotatably installed on the lower side of the adjusting rod 4. The threaded rod 5 is threaded through the fixed rod 3 and extends to the lower side. A turntable 6 is fixedly installed on the outer end of the threaded rod 5. Slider blocks 7 are fixedly installed on both sides of the adjusting rod 4. Two sets of sliding grooves 8 for connecting the sliders 7 are opened through the outer side of the support frame 2. The sliders 7 move through the sliding grooves 8 and extend to the outer side. A reinforcing mechanism for connecting the sliders 7 is provided on the outer side of the sliding grooves 8. When the turntable 6 rotates and drives the threaded rod 5 to rotate, the adjusting rod 4 can be driven to move vertically upward or downward through the limiting effect of the sliders 7 and the sliding grooves 8. This facilitates the adjustment of the height of the adjusting rod 4, meets various usage needs, improves the ease of operation for maintenance personnel, and ensures operational safety.

[0029] Specifically, the reinforcement mechanism includes a mounting block 9 fixedly installed on the outside of the slider 7. Two sets of fixing bolts 10 are provided on the outside of the mounting block 9. Both sets of fixing bolts 10 are threaded through the mounting block 9 and extend to the inside. Multiple sets of screw holes 11 for mating fixing bolts 10 are opened on both sides of the slide groove 8. When the fixing bolts 10 are screwed into the screw holes 11, the movable rod 4 can be further reinforced, thereby ensuring the stability of the movable rod 4 in use. At the same time, the fixing bolts 10 are thumb bolts, which can be easily tightened without the aid of other tools, improving the ease of use.

[0030] Furthermore, multiple sets of hooks 12 are movably provided on the outer side of the adjusting rod 4. These hooks 12 can hold tools and materials for repairing the generator blades. The main repair materials for the generator blades include polyurethane and epoxy resin. By placing the polyurethane and epoxy resin in a dedicated storage container and then hanging the storage container on the hooks 12, the staff can easily take out the polyurethane and epoxy resin from the storage container for use.

[0031] It is worth noting that a connecting rod 13 is fixedly installed on the outside of the hook 12, and a T-shaped slider 14 is fixedly installed on the outside end of the connecting rod 13. A T-shaped groove 15 is opened on the outside of the adjusting rod 4 to engage with the T-shaped slider 14. By moving the hook 12, the T-shaped slider 14 can be driven to slide in the T-shaped groove 15, thereby facilitating the adjustment of the position of the hook 12, which in turn facilitates the adjustment of the position of maintenance tools and materials, further improving the ease of operation for maintenance personnel. At the same time, the hook 12 and the connecting rod 13 are connected by a threaded connection, which makes it easy to replace the hook 12 when it is damaged.

[0032] It is worth noting that limit blocks 16 are fixedly installed on both sides of the slider 7, and limit grooves 17 that engage with the limit blocks 16 are opened on both sides of the slide groove 8. When the slider 7 moves, it can drive the limit blocks 16 to slide within the limit grooves 17, thereby further limiting the adjustment rod 4 and further improving its stability and strength.

[0033] In addition, a reinforcing rib 18 is fixedly installed on the inner side of the support frame 2. The reinforcing rib 18 is X-shaped and can support and reinforce the support frame 2, thereby ensuring its strength.

[0034] It must be said that multiple anti-slip blocks 19 are fixedly installed on the outer side of the turntable 6. All anti-slip blocks 19 are made of soft material. By setting anti-slip blocks 19, the friction of the turntable 6 can be improved, avoiding slippage when rotating the turntable 6, making it more convenient for maintenance personnel to rotate the turntable 6.

[0035] Working principle: First, the operator rotates the turntable 6 according to their own height. When the turntable 6 rotates, it drives the adjusting rod 4 to move until the adjusting rod 4 is moved to the appropriate position. Then, the fixing bolts 10 on both sides are screwed into the corresponding screw holes 11 to fix the adjusting rod 4. After that, the operator can hang the tools needed for maintenance on the hook 12. The hook 12 is easy to move, so it is easy to move the tools to the appropriate position for the operator to use, thus improving the operator's ease of operation.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
