[0002] A wind turbine tower platform is a platform installed inside a wind turbine tower. It primarily supports and absorbs vibrations from the turbine. It is typically constructed from multiple bent steel plates that are joined and locked together. It features a simple structure, light weight, and quick and easy installation, simplifying the platform's processing and assembly processes. The wind turbine tower platform cover is a lid installed on the platform inside the wind turbine tower. Its primary function is to improve the safety of maintenance personnel while maintaining equipment. It also provides dust and water resistance, protecting the equipment and structures inside the wind turbine tower and keeping the interior of the tower clean.

[0003] Currently, most of the existing wind turbine tower platform covers are opened and closed manually and cannot be opened and closed automatically, which makes it impossible to use the free-climbing device. In addition, the existing automatic opening and closing control system cannot open the cover in a timely and effective manner during use, thereby increasing the user's workload and working time, and thus reducing the user's work efficiency.

When problems occur during use, the user's workload and working time are increased, thereby reducing the user's work efficiency. Through this solution, the opening and closing work can be automatically, timely and effectively performed without affecting the normal use of the climb-free device body. At the same time, if the device fails, the electric push rod can also be mechanically controlled to ensure the normal opening and closing of the first cover and the second cover. If the electric push rod in the device fails, the user can also mechanically open and close the second cover, further ensuring the normal use of the device, without worrying that the user will not be able to open the second cover in time and effectively, thereby reducing the user's workload and working time, thereby improving the user's work efficiency.

[0013] How the device operates:

[0014] Step 1: Automatic opening. When the user climbs the main body of the free climbing device, the main body of the free climbing device is monitored by the first opening sensor. Then, the main controller controls the electric push rod to work. The electric push rod is shortened to rotate the first cover plate and the second cover plate, thereby opening the first cover plate and the second cover plate. When the user passes through the working platform, the main controller controls the electric push rod to extend, and then the first cover plate and the second cover plate are closed. When the user goes down through the main body of the free climbing device, the main body of the free climbing device is monitored by the second opening sensor. Then, the main controller controls the electric push rod to work, thereby opening the first cover plate and the second cover plate. When the user and the main body of the free climbing device pass through the working platform, the first cover plate and the second cover plate are closed.

[0015] When the first and second pressure switches are in the closed position, the first and second pressure switches are in the closed position, and the first and second pressure switches are in the closed position, and the second pressure switches are in the closed position, and the first and second pressure switches are in the closed position, and the second pressure switches are in the closed position, and the first and second pressure switches are in the closed position, and the second pressure switches are in the closed position, and the second pressure switches are in the closed position, and the first and second pressure switches are in the closed position, and the second pressure switches are in the closed position, and the second pressure switches are in the closed position, and the first and second pressure switches are in the closed position, and the second pressure switches are in the closed position, and the second pressure switches are in the closed position, and the first and second pressure switches are in the closed position, and the second pressure switches are in the closed position, and the second pressure switches are in the closed position, and the

[0016] Step 3: Manual opening. When there is a problem with the electric push rod or the main controller, the user pulls the pull plate, which drives the slider and the fixed slide to move through the connecting block. When one end of the fixed slide is no longer in the fixed groove, the user can open the second cover through the handle and then pass through the work platform.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] When the user is using the device, when the user is climbing through the free climbing device body, the first opening sensor can monitor the free climbing device body, and then the main controller controls the electric push rod to work, and the electric push rod is shortened to rotate the first cover plate and the second cover plate, so that the first cover plate and the second cover plate are opened, thereby facilitating the free climbing device body and the user to pass through the working platform. After the user has passed through the working platform, the main controller controls the electric push rod to extend, and then closes the first cover plate and the second cover plate. When the user goes down through the free climbing device body, the second opening sensor monitors the free climbing device body, and then the main controller controls the electric push rod to work, thereby opening the first cover plate and the second cover plate. When the user and the free climbing device body pass through the working platform, the first cover plate and the second cover plate are opened. When the first opening sensor or the second opening sensor fails, the detection opener can detect that the second cover is in a stationary state. At this time, the detection opener enables the first pressure switch or the second pressure switch to work through the main controller. When the main body of the non-climbing device moves up, when the main body of the non-climbing device conflicts with the first inclined plate at the inclined surface of the bottom end of the first inclined surface receiving block, the first inclined plate rotates to one side of the first pressure switch and compresses the first torsion spring. The rotating first inclined plate can press down the first pressure switch, and the electric push rod is controlled to work through the first pressure switch. The first cover and the second cover are opened by the electric push rod. After one end of the non-climbing device main body conflicts with the inclined surface of the first inclined surface receiving block, When the first ramp is lifted and the user passes through the work platform, the first cover plate and the second cover plate are closed again. When the free-climbing body continues to move up, the free-climbing body conflicts with the inclined surface on one side of the bottom end of the second ramp receiving block, causing the second ramp receiving block to move toward the inside of the second receiving groove, thereby not touching the second inclined plate and the second pressure switch at one end of the second ramp receiving block. When the free-climbing body moves down, the free-climbing body conflicts with the second inclined plate at the inclined surface of the top end of the second ramp receiving block, and presses the second pressure switch downward through the second inclined plate, thereby causing the first cover plate to When the user has stepped onto the platform, the first and second covers are closed again, and the main body of the free-climbing device continues to move downward, and the main body of the free-climbing device collides with the inclined surface at the top of the first inclined cover block, causing the first inclined cover block to move toward the inside of the first receiving groove, thereby not touching the first inclined plate and the first pressure switch, thereby ensuring that the device is in a normal state. When multiple people need to maintain the device, the safety and reliability of the device are further improved through the secondary automatic opening, and there is no need to worry about the main body of the free-climbing device being unable to return. At the same time, the first cover and the second cover are in a closed state during the user's maintenance, which meets the requirements of standard specifications. When there is a problem with the electric push rod or the main controller, the user pulls the pull plate at this time.The pull plate drives the slider and the fixed slide plate to move through the connecting block. When one end of the fixed slide plate is no longer in the fixed groove, the user can open the second cover plate through the handle and then pass through the work platform. The pull plate, the slider and the fixed slide plate can ensure that the user can open the second cover plate at any time, further ensuring the normal use of the device without affecting the user's maintenance work. The device can automatically open and close the device in a timely and effective manner without affecting the normal use of the main body of the non-climbing device. At the same time, if a failure occurs in the device, the electric push rod can also be mechanically controlled to ensure the normal opening and closing of the first cover plate and the second cover plate. If the electric push rod in the device fails, the user can also mechanically open and close the second cover plate, further ensuring the normal use of the device, without worrying about the user not being able to open the second cover plate in a timely and effective manner, thereby reducing the user's workload and working time, thereby improving the user's work efficiency. At the same time, when multiple people are working, there is no need to worry about the non-climbing device main body being unable to return. BRIEF DESCRIPTION OF THE DRAWINGS

The sizes of the fixed slide 40 are respectively adapted to the fixed groove 33 and the through groove 36, the sizes of the slider 37 are respectively adapted to the slide groove 34, and the sizes of the connecting block 39 are respectively adapted to the connecting groove 35. The adapted sizes can ensure the stability of the movement of the fixed slide 40, the slider 37 and the connecting block 39;

[0035] The device operates as follows:

[0036] Step 1: Automatic opening. When the user climbs through the main body 5 of the free climbing device, the main body 5 of the free climbing device can be monitored by the first opening sensor 14. Then, the main controller 6 controls the electric push rod 11 to work. The shortening of the electric push rod 11 can make the first cover plate 7 and the second cover plate 8 rotate, so that the first cover plate 7 and the second cover plate 8 are opened. When the user passes through the working platform 2, the main controller 6 controls the electric push rod 11 to extend, and then the first cover plate 7 and the second cover plate 8 are closed. When the user goes down through the main body 5 of the free climbing device, the main body 5 of the free climbing device is monitored by the second opening sensor 24. Then, the main controller 6 controls the electric push rod 11 to work, so that the first cover plate 7 and the second cover plate 8 are opened. When the user and the main body 5 of the free climbing device pass through the working platform 2, the first cover plate 7 and the second cover plate 8 are closed.

[0037] Step 2: The machine automatically opens. When the first opening sensor 14 or the second opening sensor 24 has a problem, the detection opener 12 detects that the second cover plate 8 is in a stationary state. At this time, the detection opener 12 makes the first pressure switch 22 or the second pressure switch 29 work through the main controller 6. When the free-climbing device body 5 moves up, when the free-climbing device body 5 contacts the first inclined plate 19 at the bottom inclined surface of the first inclined surface receiving block 16, the first inclined plate 19 can press down the first pressure switch 22, and the electric push rod 11 is controlled to work through the first pressure switch 22. Then the first cover plate 7 and the second cover plate 8 are opened. When the climbing-free device body 5 and the user pass through the working platform 2, the first cover plate 7 and the second cover plate 8 are closed again. When the climbing-free device body 5 moves downward, the climbing-free device body 5 contacts the second inclined plate 30 at the top inclined surface of the second inclined surface receiving block 26, and the second pressure switch 29 is pressed downward by the second inclined surface 30, thereby opening the first cover plate 7 and the second cover plate 8. At the same time, the second inclined surface receiving block 26 slides toward the inside of the second receiving groove 25. When the climbing-free device body 5 and the user pass through the working platform 2, the first cover plate 7 and the second cover plate 8 are closed again.

[0038] Step 3: Manual opening. When a problem occurs with the electric push rod 11 or the main controller 6, the user pulls the pull plate 41, and the pull plate 41 drives the slider 37 and the fixed slide 40 to move through the connecting block 39. When one end of the fixed slide 40 is no longer inside the fixed groove 33, the user can open the second cover 8 through the handle 9 and then pass through the work platform 2.

[0039] Working principle: When the user is using this device, when the user is climbing through the non-climbing device body 5, the first opening sensor 14 can monitor the non-climbing device body 5, and then the main controller 6 controls the electric push rod 11 to work, and the electric push rod 11 is shortened, and the connecting member 10 is pulled by the electric push rod 11. The connecting member 10 pulls one end of the first cover plate 7, so that the first cover plate 7 and the second cover plate 8 can be rotated, so that the first cover plate 7 and the second cover plate 8 are opened, thereby facilitating the non-climbing device body 5 and the user to pass through the working platform 2. When the user passes through the working platform 2, the main controller 6 controls the electric push rod 11 to extend, and then the first cover plate 7 and the second cover plate 8 are closed. When the user goes down through the non-climbing device body 5, the second opening sensor 14 controls the electric push rod 11 to work, and the main controller 6 controls the electric push rod 11 to shorten, and the connecting member 10 is pulled by the electric push rod 11. The connecting member 10 pulls one end of the first cover plate 7, so that the first cover plate 7 and the second cover plate 8 are rotated, so that the first cover plate 7 and the second cover plate 8 are opened, thereby facilitating the non-climbing device body 5 and the user to pass through the working platform 2. The start sensor 24 monitors the main body 5 of the free climbing device, and controls the electric push rod 11 to work through the main controller 6, thereby opening the first cover plate 7 and the second cover plate 8. When the user and the main body 5 of the free climbing device pass through the working platform 2, the first cover plate 7 and the second cover plate 8 are closed, thereby facilitating the user's maintenance work. When the first opening sensor 14 or the second opening sensor 24 has a problem, the detection opener 12 can detect that the second cover plate 8 is in a stationary state. At this time, the detection opener 12 makes the first pressure switch 22 or the second pressure switch 29 work through the main controller 6. When the main body 5 of the free climbing device moves upward, when the main body 5 of the free climbing device conflicts with the first inclined plate 19 at the bottom inclined surface of the first inclined surface receiving block 16, the first inclined plate 19 moves to the first pressure switch 22. One side of the device rotates and compresses the first torsion spring 21 at the same time. The rotating first inclined plate 19 can press down the first pressure switch 22, and the first pressure switch 22 controls the electric push rod 11 to work. The electric push rod 11 then opens the first cover plate 7 and the second cover plate 8. After one end of the free climbing device body 5 conflicts with the inclined surface of the first inclined surface receiving block 16, the first inclined surface receiving block 16 can slide toward the inside of the first receiving groove 15, and the first inclined surface receiving block 16 compresses the first spring 17. When one end of the free climbing device body 5 no longer conflicts with the first inclined surface receiving block 16, the first inclined surface receiving block 16 is reset under the action of the first spring 17. When the free climbing device body 5 and the user pass through the working platform 2, the first cover plate 7 and the second cover plate 8 are again When the lifting device 5 is closed for the second time, the lifting device 5 continues to move upward, and the lifting device 5 contacts the inclined surface of one side of the bottom end of the second inclined surface receiving block 26, so that the second inclined surface receiving block 26 moves toward the inside of the second receiving groove 25, thereby not touching the second inclined plate 30 and the second pressure switch 29 at one end of the second inclined surface receiving block 26. When the lifting device 5 moves downward, the lifting device 5 contacts the second inclined plate 30 at the inclined surface of the top end of the second inclined surface receiving block 26, and presses the second pressure switch 29 downward through the second inclined plate 30, thereby opening the first cover plate 7 and the second cover plate 8. At the same time, the second inclined surface receiving block 26 slides toward the inside of the second receiving groove 25. When the lifting device 5 and the user pass through the working platform 2, the first cover plate 7 and the second cover plate 8 are closed again, and the lifting device 5 continues to move downward.The main body 5 of the anti-climbing device 10 conflicts with the inclined surface of the top end of the first inclined surface receiving block 16, so that the first inclined surface receiving block 16 moves toward the inside of the first receiving groove 15, thereby not touching the first inclined plate 19 and the first pressure switch 22, thereby ensuring that the device is in a normal state. When multiple people need to maintain it, the safety and reliability of the use of the device are further improved through the secondary automatic opening, and there is no need to worry about the main body 5 of the anti-climbing device 10 being unable to return. At the same time, the first cover plate 7 and the second cover plate 8 are in a closed state during user maintenance, which meets the requirements of standard specifications. When there is a problem with the electric push rod 11 or the main controller 6, the user pulls the pull plate 41, and the pull plate 41 drives the slider 37 to slide inside the slide groove 34 through the connecting block 39. The moving slider 37 compresses the third spring 38. At the same time, the slider 37 drives the fixed slide plate 40 to move, and the fixed slide plate 40 slides inside the through groove 36 and the fixed groove 33. When one end of the fixed slide plate 40 is no longer inside the fixed groove 33 At this time, the user can open the second cover plate 8 through the handle 9, and then can pass through the work platform 2. The pull plate 41, the slider 37 and the fixed slide 40 can ensure that the user can open the second cover plate 8 at any time, further ensuring the normal use of the device and will not affect the user's maintenance work. The device can automatically, timely and effectively perform opening and closing operations without affecting the normal use of the non-climbing device body 5. At the same time, if a failure occurs in the device, the electric push rod 11 can also be mechanically controlled to ensure the normal opening and closing of the first cover plate 7 and the second cover plate 8. If the electric push rod 11 in the device fails, the user can also mechanically open and close the second cover plate 8, further ensuring the normal use of the device, without worrying that the user will not be able to open the second cover plate 8 in a timely and effective manner, thereby reducing the user's workload and working time, thereby improving the user's work efficiency. At the same time, when multiple people are working, there is no need to worry that the non-climbing device body 5 cannot return.
