Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation equipment, in particular to a wind turbine set anti-climbing device. Background Art

[0002] The wind power source consists of a wind turbine generator set, a tower supporting the generator set, a battery charge controller, an inverter, a load unloader, a grid connection controller, a battery pack, etc. The wind turbine generator set includes a wind wheel and a generator; the wind wheel contains blades, a hub, reinforcements, etc.; it has the functions of blades rotating under wind power to generate electricity and the generator head rotating.

[0003] When performing maintenance and inspection on the inside of a wind turbine, maintenance personnel usually stand on an anti-climbing device and then use the anti-climbing device to move up and down in the narrow space. Although the current anti-climbing device can realize the smooth up and down movement of the staff, there is no support for the waist when climbing, and the staff needs to control the body to be upright. Once the body tilts, it is very easy to cause the back of the staff to contact and rub against the rear wall of the cylinder, which may cause friction and contamination of clothes at the least, and damage clothes and friction injury to the back at the worst. Therefore, a wind turbine anti-climbing device is proposed to address the above problems. Utility Model Content

[0004] The utility model aims to provide a wind turbine anti-climbing device to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] As an optional solution of the wind turbine non-climbing device described in the utility model, wherein: a wind turbine non-climbing device comprises a non-climbing device and a ladder, the non-climbing device is installed on the outside of the ladder, and a foot pedal for workers to stand is installed on the front side of the non-climbing device, an operation panel is fixedly connected to the top of the non-climbing device, and handles fixedly connected to the non-climbing device are provided on both sides of the operation panel, and the outer sides of the handles are rotatably connected to support components;

[0007] The support assembly includes a rotating rod, one end of which is rotatably connected to the handle, a first support rod is fixedly connected to the outer side of the rotating rod, and the other end of the rotating rod is fixedly connected to a transversely arranged second support rod, a movable plate is provided between the first support rod and the second support rod, a sliding frame is slidably connected to the outer side of the movable plate, and one end of the sliding frame is fixedly connected to the rotating rod.

[0008] When performing maintenance and inspection on the inside of a wind turbine, maintenance personnel usually stand on the non-climbing device and then use the non-climbing device to move up and down in the narrow space. However, although the current non-climbing device can realize the smooth up and down movement of the staff, there is no support for the waist when climbing, and the staff needs to control the body to be upright by themselves. Once the body tilts, it is very easy to cause the staff's back to contact and rub against the rear wall of the cylinder, which may cause friction and contamination of clothes at the least, or damage clothes and cause friction and injury to the back at the worst. When the present device is used, the staff stands on the foot pedal, and the staff can rotate the rotating rod on one side, and then the waist enters between the first support rod and the second support rod and squeezes the moving plate, and then rotates the rotating rod on the other side to position the waist on the other side between the first support rod and the second support rod on the other side, and then install the safety pendant and test its stability. At this time, when climbing, the second support rod can play a good role in supporting the staff's back, avoiding the staff's back from contacting and abrading with the cylinder wall when climbing or descending, and playing a good protective purpose. The safety pendant belongs to the existing products in this field, so it will not be described in detail here.

[0009] As an optional solution of the wind turbine non-climbing device described in the utility model, there are two groups of support components, and the support components are arranged in a left-right symmetrical manner with respect to the center of the ladder.

[0010] This arrangement can provide good support to the workers when they move through the support assembly, preventing the workers from leaning back and coming into contact with the cylinder wall and getting injured.

[0011] As an optional solution of the wind turbine anti-climbing device described in the utility model, wherein: raised bumps are provided on both sides of the foot pedal, and a blocking plate is fixedly connected to the front side of the foot pedal.

[0012] The bumps on both sides of the pedal and the blocking plate on the front side are very inconvenient once the foot steps on the bumps and the blocking plate. It can be known that there is a certain safety hazard if the foot goes over the pedal, reminding the staff to retract the foot.

[0013] As an optional solution of the wind turbine anti-climbing device described in the utility model, wherein: a rubber plate is fixedly connected to one side of the movable plate, and the rubber plate is arranged in an arc shape.

[0014] When the worker moves upward, the waists on both sides of the worker are in contact with the rubber plates, which can limit and protect the waists of the worker, allowing the worker to perform normal upward movement.

[0015] As an optional solution of the wind turbine anti-climbing device described in the utility model, the movable plate is slidably connected to a sliding plate inside, a sliding rod is fixedly connected to one side of the sliding plate, and the other end of the sliding rod is fixedly connected to the sliding frame.

[0016] As an optional solution of the wind turbine anti-climbing device described in the utility model, a spring is provided on the outer side of the sliding rod, one side of the spring is fixedly connected to the moving plate, and the other side of the spring is fixedly connected to the sliding plate.

[0017] The sliding plate and sliding rod are arranged to ensure that the moving plate is not easily separated from the sliding frame. At the same time, the moving plate can be moved toward the center under the action of the spring to support and limit the staff. At the same time, the device is not easily separated from the staff, which plays a good protective support purpose.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The utility model provides a rotating rod, a first support rod and a second support rod on the outer side of the handle. When the worker uses the non-climbing device to move up and down, the worker can rotate the rotating rod on one side, and then put the waist between the first support rod and the second support rod and squeeze the moving plate, and then rotate the rotating rod on the other side to position the waist on the other side between the first support rod and the second support rod on the other side. At this time, when climbing, the second support rod can play a good role in supporting the worker's back, avoiding the worker's back from being worn and injured by contact with the cylinder wall when climbing or descending.

[0020] The spring can ensure the movement of the moving plate, and the rubber plate inside the moving plate contacts the waist of the worker, which can serve as a support. The sliding rod and sliding plate can limit the waist of the worker to prevent the worker from shaking at will during movement, which serves a certain protection purpose.

[0021] The foot pedals and blocking plates are provided to ensure that the feet of the staff are located inside the foot pedals when standing, avoiding partial leakage that may cause collision and injury due to contact with other surrounding objects when moving upwards, thereby playing a certain role in protecting the feet.
