Description

Technical Field

[0001] This utility model relates to the technical field of drilling, specifically a drilling device for wind turbine blades. Background Technology

[0002] Wind power generation refers to converting the kinetic energy of wind into electrical energy. Wind energy is a clean and pollution-free renewable energy source that has been utilized by people for a long time, mainly through windmills for pumping water and grinding grain. People are interested in how to use wind to generate electricity. Wind turbine blades are the core components of wind turbine units that convert natural wind energy into electrical energy, and they are also the main basis for measuring the design and technical level of wind turbine units. Wind turbine units can be roughly divided into three parts: wind rotor, generator, and tower. The wind rotor is also called wind turbine blade. In order to install and stabilize the wind turbine blades, holes need to be drilled at the root of the wind turbine blade.

[0003] For example, Chinese utility model patent CN216370247U discloses a wind turbine blade drilling device, including a housing, an opening and closing door, and support legs. The support legs are provided at the bottom of the housing, and the opening and closing door is provided at the front of the housing. The housing includes a moving mechanism, a threaded rod, a sliding block, a hydraulic rod, a motor, a threaded rotating rod, a moving plate, a fixing block, a through hole, an arc groove, an anti-slip mechanism, a transmission mechanism, and a threaded drill bit. The sliding block is fixedly connected to the top of the inner wall of the housing. The threaded rod is rotatably connected to the left side of the sliding block through a rotating shaft. The moving mechanism is provided on the outer surface of the threaded rod. This utility model limits the position of the transmission rod by setting a transmission block. By rotating the transmission rod, the pulley disc can drive the pulley disc on the surface of the threaded rotating rod to rotate, which can adjust the height of the moving plate. This allows employees to clamp the fan blades from the outside of the housing, increasing employee safety.

[0004] However, in the actual drilling process, the existing device fixes the blades longitudinally. Therefore, when drilling is required at different positions on the blades, the blades need to be flipped over and fixed again, which increases the complexity of the operation and reduces the drilling efficiency of the device. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a wind turbine blade drilling device that facilitates drilling operations at different positions on the blade, increases the drilling range of the device, improves the drilling efficiency of the device, and enhances its practicality.

[0006] This utility model discloses a wind turbine blade drilling device, including a worktable. A support platform is rotatably mounted on the top of the worktable via a rotating shaft. Two clamping mechanisms are symmetrically arranged on the top of the support platform. Each clamping mechanism includes two fixed rods, which are symmetrically fixedly mounted on the top of the rotating shaft. The tops of the two fixed rods are fixedly connected by a connecting rod. Two limiting rods are symmetrically fixedly mounted laterally on each of the two fixed rods. Two bidirectional screws are symmetrically rotated laterally on each of the two fixed rods. Sliding rods are slidably mounted on each of the two connecting rods. Each sliding rod is screwed onto a bidirectional screw. A sliding groove is formed on the opposite side of each sliding rod. Multiple fixing plates are slidably mounted between two sliding grooves.

[0007] Two drilling mechanisms are symmetrically installed at the top of the workbench. This wind turbine blade drilling device rotates a bidirectional screw while simultaneously driving two sliding rods to move in opposite directions under the control of two limit rods. After the blade is moved between the two sliding rods, the height of each fixing plate on the slide groove is adjusted, so that the fixing plate closest to the blade fits tightly against the blade, thus completing the blade fixing operation. By rotating the support platform, the blade's angle is simultaneously adjusted. The drilling mechanism can drill holes at different positions on the blade, which facilitates drilling at different locations on the blade, increases the drilling range of the device, improves the drilling efficiency of the device, and enhances its practicality.

[0008] Preferably, the drilling mechanism includes a vertical plate and a first motor. A limiting groove is provided on the vertical plate, and a sliding mechanism is provided at the bottom end of the first motor. The sliding mechanism includes a base plate, and a drilling bit is fixedly installed at the output end of the first motor. The bottom end of the first motor is slidably connected to the top end of the base plate, and a cylinder is fixedly installed at the top end of the base plate. The output end of the cylinder is fixedly connected to the outer side wall of the first motor. The base plate is slidably connected to the limiting groove. Power is output through the cylinder, which synchronously drives the first motor and the drilling bit to perform lateral movement. Power is output through the first motor, which drives the drilling bit to rotate at high speed. The high-speed rotating drilling bit performs drilling operations on the fixed blade.

[0009] Preferably, a first screw is longitudinally rotatably installed in the middle region of the upright plate. The first screw is screwed to the base plate. By rotating the first screw, the base plate is simultaneously driven to adjust its height on the limiting groove. By moving the base plate, the cylinder, the first motor and the drilling bit are simultaneously driven to adjust their height, which facilitates the device to drill holes in different areas of the blade.

[0010] Preferably, a second motor is fixedly installed at the top of the upright plate, and the output end of the second motor is fixedly connected to the top of the first screw. By installing the second motor, it is convenient to provide power support to the first screw.

[0011] Preferably, each of the base plates has a support plate fixedly installed at its top by two brackets. The support plate is slidably connected to the outer wall of the upright plate. By installing the brackets and the support plate, it is convenient to provide stable support for the base plate during sliding operations.

[0012] Preferably, a plurality of third screws are screwed onto the outer side wall of the support platform, and a fixed seat is rotatably installed at the bottom end of each third screw. By rotating the third screw, the fixed seat is moved synchronously, and the bottom end of the fixed seat is tightly fitted with the top end of the support platform, thereby completing the fixing operation of the support platform.

[0013] Preferably, two protective plates are symmetrically fixedly installed on the top of the support platform. By installing the protective plates, it is convenient to limit the bottom area of ​​the blade.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This wind turbine blade drilling device, by rotating the bidirectional screw, simultaneously drives two sliding rods to move in opposite directions under the limitation of two limiting rods. After the blade is moved between the two sliding rods, the height of each fixing plate on the sliding groove is adjusted, so that the fixing plate closest to the blade fits tightly with the blade, thereby completing the blade fixing operation. By rotating the support platform, the blade angle is simultaneously adjusted. The drilling mechanism can drill holes at different positions on the blade, which facilitates drilling operations at different positions on the blade, increases the drilling range of the device, improves the drilling efficiency of the device, and enhances its practicality.
