[0002] A wind turbine is an electrical device that can convert wind energy into mechanical energy, use this mechanical energy to drive the rotor to rotate, and ultimately output alternating current. In a wind turbine, blades are one of its main components. In order to make the blades rotate better, people generally install guide devices on the blades to make the wind turbine's power generation effect better.

[0003] A blade guide device for a wind turbine is disclosed in the Chinese utility model patent application disclosure specification CN215370112U. The blade guide device for a wind turbine uses a metal protective net to prevent large floating garbage (such as balloons, kites, plastic bags, etc.) from entering the annular guide bracket and causing blockage. At the same time, it can prevent birds from colliding with the blade body when flying, which can reduce the death of birds and prevent the blades from being damaged. However, the metal protective net of the wind turbine blade guide device will be covered with dust after long-term use. In order to prevent dust from clogging the metal protective net, the metal protective net needs to be cleaned. The metal protective net is located at a relatively high height. When cleaning the metal protective net, the cleaning personnel need to go up to a high place to perform the cleaning operation. Not only does it make the operation of cleaning the metal protective net more troublesome, but the cleaning personnel also have certain risks in the process of cleaning the metal protective net. Therefore, a blade guide device for a wind turbine is needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0021] like Figures 1 to 5As shown, a blade guide device for a wind turbine generator comprises a tower 1, a base 2 is fixedly mounted on the top of the tower 1, a generator structure 3 is provided on the base 2, a connecting frame 4 is fixedly connected to the outer surface of the base 2, and a guide cover 5 is fixedly connected to the end of the connecting frame 4 away from the base 2. The guide cover 5 is supported by the connecting frame 4 to ensure the structural stability of the guide cover 5. A metal mesh cover 6 is fixedly mounted on one side of the guide cover 5. An L-shaped bracket 7 is fixedly connected to the outer surface of the base 2, and one end of the L-shaped bracket 7 is rotated. It is connected to a connecting block 8, the bottom end of the connecting block 8 is fixedly connected to a rotating plate 9, a reduction motor 10 is fixedly installed on one side of the rotating plate 9, the output end of the reduction motor 10 is fixedly connected to a first pulley 11, the first pulley 11 is connected to a second pulley 12 through a belt drive, the keyway inner wall of the second pulley 12 is fixedly connected to a rotating shaft 13, one end of the rotating shaft 13 is fixedly installed with a cleaning brush plate 14, a U-shaped bracket 15 is fixedly connected to one side of the rotating plate 9, and an adjustment The adjusting structure 16 of the rotating plate 9 angle, two control switches 17 and a display screen 18 are provided at the bottom end of the tower 1, and a camera 19 is fixedly installed on one side of the rotating plate 9. When it is necessary to clean the dust on the metal mesh cover 6, the U-shaped bracket 15 is first driven by the adjusting structure 16 to drive the rotating plate 9 and the connecting block 8 to rotate to a vertical state. At this time, the center position of the rotating shaft 13 corresponds to the center position of the metal mesh cover 6, and the bristles on the cleaning brush plate 14 are in contact with the metal mesh cover 6. Then, the reduction motor 10 is started by a control switch 17, and the rotating shaft 13 drives the cleaning brush plate 14 to rotate under the transmission action of the first pulley 11, the belt and the second pulley 12. As the cleaning brush plate 14 rotates, the metal mesh cover 6 is cleaned. In this process, the camera 19 captures the image of the metal mesh cover 6 and displays it on the display screen 18, so that the cleaning status of the metal mesh cover 6 can be observed. When the cleaning operation of the metal mesh cover 6 is completed, the cleaning brush plate 14 is rotated to the bottom position of the metal mesh cover 6, as shown in FIG. Figure 2 As shown, interference between the cleaning brush plate 14 and the metal mesh cover 6 can be avoided during the process of retracting the cleaning brush plate 14. Then, the U-shaped bracket 15 is driven to lift the rotating plate 9 by adjusting the structure 16, so that the rotating plate 9 and its connecting components no longer block the metal mesh cover 6.

[0022] As an optional technical solution of the present invention, an L-shaped baffle 20 is fixedly installed on one side of the L-shaped bracket 7, and one end of the L-shaped baffle 20 corresponds to the position of the rotating plate 9. The L-shaped baffle 20 can block the rotating plate 9 to prevent the rotating plate 9 from being in a tilted state during cleaning, so that the cleaning brush plate 14 can better clean the metal mesh cover 6.

[0023] As an optional technical solution of the present invention, the adjustment structure 16 includes a first articulated seat 1601, an electric push rod 1602 and a second articulated seat 1603. The first articulated seat 1601 is fixedly installed on one side of the L-shaped bracket 7. The electric push rod 1602 is hinged to one side of the first articulated seat 1601. The output end of the electric push rod 1602 is hinged to the second articulated seat 1603 fixedly connected to the U-shaped bracket 15.

[0024] As an optional technical solution of the present invention, the metal mesh cover 6 and the cleaning brush plate 14 are both arc-shaped, and the bristle part of the cleaning brush plate 14 is in contact with the metal mesh cover 6, so that the cleaning brush plate 14 has a better cleaning effect on the metal mesh cover 6.

[0025] As an optional technical solution of the present invention, the rotating shaft 13 passes through one side of the rotating plate 9. The rotating shaft 13 is rotatably connected to the rotating plate 9 through a bearing, which supports the rotating shaft 13 and ensures the stability of the rotating shaft 13 during rotation.

[0026] As an optional technical solution of the present invention, the camera 19 is electrically connected to the display screen 18, so that the image captured by the camera 19 can be displayed on the display screen 18. Since it belongs to the existing technology, the working principles of the camera 19 and the display screen 18 are not specifically explained. A control switch 17 is electrically connected to the reduction motor 10, and a control switch 17 is electrically connected to the electric push rod 1602, so that the control switch 17 can control the opening and closing of the reduction motor 10 and the electric push rod 1602.

[0027] The working principle of the present invention is the same as that of a blade guide device for a wind turbine disclosed in Chinese patent CN215370112U, and the present invention only improves the external structure thereof.

[0028] A blade guide device for a wind turbine, the working principle of which is as follows:

[0029] 1) A control switch 17 is used to activate the electric push rod 1602. Under the action of the first hinge seat 1601, the second hinge seat 1603 and the connecting block 8, the U-shaped bracket 15 drives the rotating plate 9 to rotate, so that the rotating plate 9 is in a vertical position. At this time, the bristles on the cleaning brush plate 14 contact the metal mesh cover 6;

[0030] 2) The reduction motor 10 is activated by a control switch 17. The first pulley 11, the belt, and the second pulley 12 drive the rotating shaft 13 to rotate the cleaning brush plate 14. As the cleaning brush plate 14 rotates, the metal mesh cover 6 is cleaned.

[0031] 3) After the cleaning operation of the metal mesh cover 6 is completed, the position of the cleaning brush plate 14 is adjusted by turning on and off the reduction motor 10 through a control switch 17, so that the cleaning brush plate 14 rotates to the bottom position of the metal mesh cover 6;

[0032] 4) A control switch 17 is used to control the electric push rod 1602 to start, and under the action of the first hinge seat 1601, the second hinge seat 1603 and the connecting block 8, the U-shaped bracket 15 drives the rotating plate 9 to rotate, so that the rotating plate 9 rises and no longer blocks the metal mesh cover 6, thereby completing the dust cleaning operation of the metal mesh cover 6.

[0033] To sum up, the blade guide device for wind turbines, through the coordinated arrangement of the L-shaped bracket 7, the connecting block 8, the rotating plate 9, the reduction motor 10, the first pulley 11, the second pulley 12, the rotating shaft 13, the cleaning brush plate 14, the U-shaped bracket 15, the adjustment structure 16, the control switch 17, the display screen 18 and the camera 19, makes it easier to clean the metal mesh cover 6. There is no need for cleaning personnel to go up to a high place to perform cleaning operations, which reduces the labor intensity of the operator in cleaning the metal mesh cover 6. In addition, the rotating plate 9 and its connecting components can be raised when the metal mesh cover 6 does not need to be cleaned, thereby avoiding the situation where the rotating plate 9 and its connecting components block the metal mesh cover 6, thereby ensuring the guide effect of the guide cover 5.
