Description

In order to better realize the treatment and recycling of wind turbine blades, there is an urgent need for a wind turbine blade cutting device that can cut wind turbine blades safely, efficiently and environmentally.

[0003] Most of the existing wind turbine blade cutting devices are hand-held cutting machines. The operators of hand-held cutting devices are relatively close to the cutting point, with low safety. At the same time, most hand-held cutting machines use fixed semi-closed dust-proof covers. During the cutting process, the cutting blades are exposed to the outside world, and the cutting dust cannot be effectively collected, and the cutting dust drifts with the wind.

[0004] Patent US2020340207A1 fixes a saw blade through an excavator arm, and the excavator arm can be manipulated to cut the blade. It provides 6 water jet cutting systems for wetting the saw blade during cutting for dust-free cutting. Although the operator is far away from the cutting point in this patent, a fixed semi-closed dust-proof cover is used, and the diffusion of cutting dust cannot be prevented. Even with 6 water jet cutting systems, since the saw blade is exposed outside, the dust collection effect of the external water flow cutting system on dust is poor, and the uncollected dust and the dust-containing wastewater after dust collection will drift with the wind under the blowing of the strong wind in the wind farm and pollute the environment.

[0040] Embodiment 1

[0041] Refer to Figures 1 to 9 As shown, this embodiment shows a mobile on-site environmental protection cutting device for wind turbine blades. The mobile on-site environmental protection cutting device for wind turbine blades is composed of a dust-proof mechanism 31 and a cutting mechanism 32.

[0042] Among them, the cutting mechanism 32 realizes the cutting function of the wind turbine blade, and the dust-proof mechanism 31 realizes the safety protection and dust anti-diffusion function during the cutting process of the cutting mechanism 32.

[0043] The cutting mechanism 32 is specifically composed of a saw blade 321, a saw blade clamp 322, a sliding mechanism 324, a sliding structure clamp 323, a hydraulic motor 325, and a control connection mechanism 326.

[0044] Among them, the saw blade 321 is fixedly connected to the rotating shaft of the hydraulic motor 325 through the saw blade clamp 322, and the sliding mechanism 324 is fixed to the hydraulic motor 325 through the sliding structure clamp 323.

[0045] The hydraulic motor oil port 3251 is connected to the hydraulic excavator oil port through a pipeline, and the hydraulic excavator provides power for the hydraulic motor 325.

[0046] The control connection mechanism 326 is composed of a motor fixed connection mechanism 3261, a rotary reducer 3262, and an excavator fixed connection mechanism 3264.

[0047] Among them, both ends of the motor fixed connection mechanism 3261 are fixedly connected to the rotating end of the hydraulic motor 325 and the rotary reducer 3262 respectively, and rotate with the rotation of the rotating end of the rotary reducer 3262, thereby realizing multi-directional cutting.

[0048] The rotary reducer motor oil port 3263 is connected to the hydraulic excavator oil port via an oil pipe, and the hydraulic excavator provides rotational power for the rotary reducer 3262 to achieve 360° rotation of the rotary reducer 3262 rotation end.

[0049] The two ends of the excavator fixed connection mechanism 3264 are respectively connected to the fixed end of the rotary reducer 3262 and the excavator connecting rod, and swing with the telescopic movement of the excavator connecting rod, thereby realizing multi-angle cutting.

[0050] Preferably, the dustproof mechanism 31 is composed of a dust removal water sprayer 311 , a telescopic damper 312 , a dustproof shell damper fixing mechanism 313 , a sliding track 314 , a sliding area 315 , a flexible contact fiber assembly 316 and a dustproof shell 317 .

[0051] The saw blade 321 and the saw blade clamp 322 are wrapped by a dustproof shell 317. A strip groove-shaped opening is provided on the shell of the dustproof shell 317. The bottom of the strip groove-shaped opening is a sliding area 315. Sliding rails 314 are provided on the two side walls of the top of the strip groove-shaped opening. A damper fixing mechanism 313 is provided at the top of the strip groove-shaped opening. A telescopic damper 312 is provided on the damper fixing mechanism 313.

[0052] In order to further improve the contact sealing between the bottom of the dustproof shell 317 and the blade, a flexible contact fiber component 316 is set at the bottom. The flexible contact fiber component 316 is connected to the bottom of the dustproof shell 317 through a conventional bayonet method. By replacing flexible contact fiber components 316 of different lengths (1-10cm), it can adapt to the arc differences of different models of blades.

[0053] To further improve the sealing of the sliding area 315, flexible closed fibers are provided on both sides of the sliding area. The flexible fibers are fixed on one side, which avoids the risk of dust leakage in the sliding area while ensuring the movement of the hydraulic motor shaft, and increases the damping effect when the cutting mechanism 32 slides up and down.

[0054] The flexible contact fiber assembly 316 at the junction of the sliding area 315 and the bottom of the dustproof shell 317 adopts a conventional rotatable bayonet connection method, which facilitates the assembly and disassembly between the dustproof mechanism 31 and the cutting mechanism 32.

[0055] A dust cover damper fixing mechanism 313 is provided on the front of the dust cover 317 for connecting the telescopic damper 312; circular rings are provided at both ends of the telescopic damper 312 for convenient connection with the dust cover damper fixing mechanism 313 and the sliding mechanism damper fixing mechanism 3242 respectively.

[0056] On the front of the dust-proof housing 317, there is a sliding track 314. The sliding track 314 is connected to the pulley 3241 of the sliding mechanism. There is a concave groove in the middle of the pulley 3241 for sliding connection with the sliding track 314, thus realizing the connection and relative sliding function between the dust-proof mechanism 31 and the cutting mechanism 32.

[0057] Dust removal water sprayers 311 are provided on the front and back of the dust-proof housing to realize the uniform spraying of dust removal water around the contact area between the saw blade 321 and the material to be cut.

[0058] During the cutting process, the fixed connection mechanism 3264 of the excavator drives the cutting mechanism 32 to move downward under the action of the downward pressure of the hydraulic excavator. During this process, an interaction force is generated between the dust-proof mechanism 31 and the surface of the object to be cut. The pulley 3241 moves on the sliding track 314, and thus a relative movement between the sliding mechanism 324 and the sliding track 314 is generated in the sliding area 315. The function of the telescopic damper 312 is mainly to ensure the smooth relative movement between the sliding mechanism 324 and the sliding track 314. Specifically, when the cutting mechanism 32 slides downward in the sliding area 315, it provides an upward traction force, and when the cutting mechanism 32 slides upward in the sliding area 315, it provides a resistance force, playing a buffering role and further realizing the smooth relative sliding between the dust-proof mechanism 31 and the cutting mechanism 32. The dust-proof mechanism 31 is always in contact with the surface of the object to be cut, achieving an overall sealing effect.

[0059] At the same time, the cutting dust generated during the cutting process is adsorbed by the sprayed dust removal water and thrown out under the action of centrifugal force. Since an overall sealing effect is achieved between the surface of the object to be cut and the dust-proof housing 317 during the cutting process, the dust-containing dust removal water thrown out is intercepted by the dust-proof housing 317 and drips into the dust removal water circulation device under the action of gravity.

[0060] The hydraulic excavator of the present utility model is used to cooperate with the hydraulic disk saw cutting device, provide power for the hydraulic disk saw, and realize the efficient movement of the hydraulic disk saw. At the same time, through the rotation of the swing motor of the hydraulic excavator and the rotation and telescoping of the boom, jib, and connecting rod (all of which are conventional structures and not shown in the figure), the hydraulic disk saw cutting device is deflected, and thus the hydraulic disk saw cutting device can move in multiple directions and at multiple angles. It is convenient to move and the operation is flexible and simple.

[0061] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
