A wind turbine generally consists of a wind wheel, a generator (including a device), a direction regulator (tail wing), a tower, a speed limit safety mechanism and an energy storage device. When installing a wind turbine, lifting equipment is required. When the lifting equipment lifts the wind turbine parts, the wind turbine parts may fall due to unstable connection or wind force, causing losses and harm.
[0003] In view of this, a device for preventing wind turbine hoisting equipment from falling is proposed. Summary of the Invention

[0006] To achieve the above-mentioned purpose, the device of the present invention includes a mounting plate and a connecting plate, wherein the connecting plate is fixedly installed on the top of the mounting plate, a mounting seat is fixedly installed on the top of the connecting plate, a lifting rope is fixedly installed on the mounting seat, a mounting frame is fixedly installed on the bottom of the mounting plate, a lifting belt is fixedly installed on the mounting frame, a lifting fixture is fixedly installed on one end of the lifting belt, a wind turbine tower is provided on the lifting fixture, and a rotatable receiving assembly is provided on the top of the mounting plate.
[0007] To enable the L-shaped rotating rod to rotate on the support and connecting block, the rotatable receiving assembly includes a support and connecting block fixedly mounted on the top of the mounting plate, on which the L-shaped rotating rod is rotatably mounted. To ensure that the L-shaped rotating rod rotates when the drive motor rotates, a drive motor is fixedly mounted on the top of the mounting plate, and the output shaft of the drive motor is fixedly mounted to one end of the L-shaped rotating rod. To facilitate the installation and use of the fixing plate, a fixing plate is fixedly mounted on the other end of the L-shaped rotating rod, and a docking plate is provided on one side of the fixing plate.
[0008] To facilitate installation and removal of the fixed plate and docking plate, a first threaded hole is provided on both the fixed plate and the docking plate, into which a first fixing screw is screwed. A square mounting frame is fixedly mounted on the top of the docking plate, and a square connecting frame is located on top of the square mounting frame to facilitate installation and use of the square mounting frame. To allow the square connecting frame to be mounted on the square mounting frame using a second fixing screw, a second threaded hole is provided on both the square connecting frame and the square mounting frame, into which a second fixing screw is screwed. A receiving net is fixedly mounted on the bottom of the square connecting frame to facilitate receiving the wind turbine tower.
[0009] The device for preventing wind turbine hoisting equipment from falling comprises the following steps:
[0010] 1) First, fix the lifting fixture at one end of the lifting belt to the wind turbine tower, and then control the lifting rope to rise through external equipment, so that the lifting rope can lift the mounting base, mounting plate, wind turbine tower and receiving net bag;
[0011] 2) The user can then use the lifting rope to lower the receiving net bag and wind turbine tower to the ground;
[0012] 3) If no problems occur during the installation of the wind turbine tower, before the wind turbine tower is docked, start the drive motor to drive the L-shaped rotating rod to rotate, thereby driving the fixed plate and the docking plate to rotate, and then driving the square installation frame, the square connecting frame and the receiving net bag to rotate until the receiving net bag is rotated away from the bottom of the wind turbine tower. When the receiving net bag is rotated to one side, it will not affect the docking installation of the wind turbine tower.
[0013] Compared with the prior art, the beneficial effects of the invention are: the present invention is provided with a receiving net bag and an L-shaped rotating rod, and the wind turbine tower can be lifted by a lifting rope. At this time, if the wind turbine tower falls due to unstable connection or wind force, the falling wind turbine tower can be received by the receiving net bag, avoiding the wind turbine tower from falling directly to the ground, causing losses and harm. Afterwards, the user can use the lifting rope to lower the receiving net bag and the wind turbine tower to the ground. If no problems occur during the lifting of the wind turbine tower, before the wind turbine tower is docked, the user can use the L-shaped rotating rod to rotate the receiving net bag to one side so as not to affect the docking installation of the wind turbine tower.

[0020] The present invention is further described in detail below by way of examples. The examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0021] A device for preventing wind turbine hoisting equipment from falling includes a mounting plate 1 and a connecting plate 2. The connecting plate 2 is fixedly mounted on the top of the mounting plate 1. A mounting seat 3 is fixedly mounted on the top of the connecting plate 2. A hoisting rope 4 is fixedly mounted on the mounting seat 3. A mounting frame 5 is fixedly mounted on the bottom of the mounting plate 1. A hoisting belt 6 is fixedly mounted on the mounting frame 5. A hoisting fixture 7 is fixedly mounted on one end of the hoisting belt 6. A wind turbine tower 8 is provided on the hoisting fixture 7. A rotatable receiving assembly is provided on the top of the mounting plate 1. The hoisting rope 4 is conveniently fixedly connected through the mounting seat 3. Under the action of the hoisting rope 4, the wind turbine tower 8 and other components can be hoisted.
[0022] The rotatable receiving assembly includes a supporting connecting block 9, which is fixedly mounted on the top of the mounting plate 1. An L-shaped rotating rod 10 is rotatably mounted on the supporting connecting block 9. A driving motor 11 is fixedly mounted on the top of the mounting plate 1. The output shaft of the driving motor 11 is fixedly mounted on one end of the L-shaped rotating rod 10. When the driving motor 11 is working, it can drive the L-shaped rotating rod 10 to rotate.
[0023] A fixing plate 12 is fixedly installed on the other end of the L-shaped rotating rod 10, and a docking plate 13 is provided on one side of the fixing plate 12. A first threaded hole is provided on both the fixing plate 12 and the docking plate 13, and a first fixing screw 14 is screwed into the first threaded hole. A square mounting frame 15 is fixedly installed on the top of the docking plate 13, and a square connecting frame 16 is provided on the top of the square mounting frame 15. Since the docking plate 13 and the square mounting frame 15 are integrated, when the user turns out a fixing screw, the square mounting frame 15 and the fixing plate 12 can be separated, which is convenient for replacement.
[0024] A second threaded hole is provided on the square connecting frame 16 and the square mounting frame 15, and a second fixing screw 17 is screwed into the first threaded hole. A receiving net bag 18 is fixedly installed at the bottom of the square connecting frame 16. When replacing a new receiving net bag 18, the user can turn out the second fixing screw 17, and then the user can pull the square connecting frame 16 upward, thereby driving the receiving net bag 18 to rise. When the square connecting frame 16 is separated from the square mounting frame 15, the user can replace the new square connecting frame 16 and the receiving net bag 18.
[0025] When the present invention is in use, the user can first fix the lifting fixture 7 at one end of the lifting belt 6 to the wind turbine tower 8, and then control the lifting rope 4 to rise through the external device, so that the lifting rope 4 can lift the mounting base 3, the mounting plate 1, the wind turbine tower 8 and the receiving net bag 18. At this time, if the wind turbine tower 8 falls due to unstable connection or wind force, the fallen wind turbine tower 8 can fall into the receiving net bag 18, avoiding the wind turbine tower 8 falling directly to the ground and causing losses and harm. After that, the user can lift the lifting rope 4 Lower the receiving net bag 18 and the wind tower 8 to the ground. If no problems occur during the hoisting of the wind tower 8, before the wind tower 8 is docked, the user can operate the drive motor 11 to drive the L-shaped rotating rod 10 to rotate, thereby driving the fixing plate 12 and the docking plate 13 to rotate, and then driving the square mounting frame 15, the square connecting frame 16 and the receiving net bag 18 to rotate until the receiving net bag 18 is rotated away from the bottom of the wind tower 8. When the receiving net bag 18 is rotated to one side, it will not affect the docking installation of the wind tower 8.
