For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0030] The free-climber used in wind turbines is a manned lifting device used inside the tower, which mainly includes guide rails, lifting platforms, electrical control systems, drive devices and traction systems.

[0031] Guide rail: The main function of the guide rail is to maintain the smooth operation of the lifting platform. It is usually used as the stopping object of the anti-fall protection device and is usually installed on the ladder inside the tower.

[0032] Lifting platform: The lifting platform consists of a body and a platform. The body is equipped with handrails, onboard control devices, and fall protection devices. The platform is for people to stand or place supplies. It is generally designed to be foldable so that people can escape along the tower ladder in an emergency.

[0033] Electrical Control System: The electrical control system consists of an electrical control cabinet, operating devices, and limit devices, controlling the start, operation, and stop of the climb-free device. The electrical control cabinet is typically mounted at the base of the wind turbine tower or on a ladder and is equipped with a motor speed control device. Operating devices can be either onboard or wireless remote controls for transporting personnel or materials. Limit devices limit the vertical travel of the lift platform to ensure safe operation.

[0034] Drive unit: The drive unit is the power source of the free climber, including the motor, reducer, brake and drive wheel, etc. It usually adopts traction drive, using the friction between the drive wheel and the wire rope to pull the lifting platform up or down.

[0035] Traction system: The traction system generally uses a steel wire rope, which passes through the top pulley, compensation wheel and guide wheel, and is fixed at the upper and lower ends of the lifting platform to form a closed loop to ensure the effective transmission of traction force.

[0036] Most climbing aids use an external battery. The operator must connect the battery module to the device via a cable and ensure the connection is secure. External battery modules often come in a portable bag for easy portability and replacement. To charge, the operator removes the battery or battery module from the device and takes it to a charging station.

[0037] If the portable battery is exhausted or forgotten, the climber cannot be used. The battery needs to be disassembled and assembled each time it is used. This step requires the operator to have certain skills to avoid damage to the battery or the equipment. If the charging equipment is not convenient or difficult to access, the operator may need to spend extra time to find and move these devices. Battery charging may take a long time, and the operator needs to wait for the battery to be fully charged before continuing to use the climber, affecting work efficiency. After charging is completed, the operator needs to put the battery back into the climber, which also requires the operator's time and energy. In order to ensure safety and optimal performance of the equipment, the battery interface needs to be inspected and maintained before and after each charging, which increases the complexity of the operation.

[0038] Therefore, the inventors propose a wireless charging device for a wind turbine free-climbing device to solve the problem of the complicated charging process of the free-climbing device.

[0039] The present application is described in detail below with reference to the accompanying drawings and specific embodiments:

[0040] Figure 1 A schematic diagram of the installation structure of the wireless charging device for the wind turbine free-climbing device provided in an embodiment of the present application; Figure 2 A schematic diagram of the structure of the battery and the fixing bracket in the wireless charging device for the wind turbine free-climbing device provided in an embodiment of the present application; Figure 3 for Figure 1 Schematic diagram of the structure of the middle crossbeam; Figure 4 Schematic diagram of the hardware structure of the wireless charging device for the wind turbine free climber provided in an embodiment of the present application.

[0041] Reference Figures 1 to 4 As shown, an embodiment of the present application provides a wireless charging device for a wind turbine anti-climbing device, comprising: a wireless charging component, a battery 2, a timer 3 and a power supply 4; the battery 2 is fixed on the anti-climbing device 1, and the power supply 4 is fixed on one side of a ladder 5 inside the tower of the wind turbine generator set.

[0042] Specifically, after use, the climbing device 1 can be charged directly via the wireless charging assembly without removing the battery 2. This eliminates the need for disassembly and assembly of the battery 2, avoids damage to the battery 2 or the device, optimizes the charging process, and improves efficiency. The battery 2 is a rechargeable lithium-ion battery 2 or nickel-metal hydride battery 2, providing continuous power for the climbing device 1. A timer 3 precisely controls the charging time.

[0043] The wireless charging assembly includes a receiving coil 6 and a transmitting coil 7 . The transmitting coil 7 is fixed to the bottom of the ladder 5 , and the receiving coil 6 is arranged inside the battery 2 on one side close to the transmitting coil 7 .

[0044] Specifically, when transmitting coil 7 is connected to power source 4, it generates an alternating electromagnetic field, which stimulates an induced current in receiving coil 6. Through magnetic field energy transmission, transmitting coil 7 transfers electrical energy to receiving coil 6. The electrical energy in receiving coil 6 is converted into direct current, which is then charged by the control circuit within battery 2. Transmitting coil 7 is fixed to the bottom of ladder 5 to facilitate charging when the ladder 5 is not in use and is docked at the bottom of the tower.

[0045] The timer 3 is arranged below the power supply 4 and fixedly connected to the ladder 5. One end of the timer 3 is connected to the power supply 4, and the other end is connected to the transmitting coil 7 for setting the charging time.

[0046] Specifically, the timer 3 is arranged below the power source 4 and is fixedly connected to the ladder 5, which helps to protect the timer 3 from the influence of the external environment and facilitates the management and layout of the line; one end of the timer 3 is connected to the power source 4 and the other end is connected to the transmitting coil 7, which can directly control the power supply 4 to the transmitting coil 7. The operator or the management system can set a reasonable charging time according to the actual power demand of the battery 2 to ensure that the battery 2 can be fully charged within the appropriate time to avoid overcharging or undercharging.

[0047] Timer 3 can be used to automate the wireless charging process. For example, it can be set to automatically start charging at night when the wind speed is low, taking advantage of off-peak electricity prices, reducing costs, and minimizing the impact on the normal operation of the wind turbine.

[0048] The present application provides a wireless charging device for a wind turbine free climber 1. By setting a wireless charging component and a timer 3, the operator can charge the portable battery 2 of the free climber 1 by presetting the charging time on the timer 3 after the free climber 1 is used and stops the body of the free climber 1 at the bottom of the ladder 5, thereby increasing the convenience of work and eliminating the need to disassemble the battery 2 and bring it back for charging.

[0049] In some embodiments, the above-mentioned wind turbine anti-climbing device 1 wireless charging device also includes a comparator 8, which is arranged between the timer 3 and the transmitting coil 7. The first input end of the comparator 8 is connected to the timer 3, the second input end is externally connected to a preset current threshold, and the output end is connected to the transmitting coil 7.

[0050] Specifically, when it detects that battery 2 is fully charged, that is, when the charging current drops below a preset current threshold, comparator 8 automatically adjusts its output, thereby controlling transmitting coil 7 to stop supplying power, achieving automatic power-off. This process prevents overcharging of battery 2, extends the service life of battery 2, and improves charging safety.

[0051] In some embodiments, the wireless charging device for the wind turbine anti-climbing device 1 further includes a circuit protector 9, which is arranged between the timer 3 and the power supply 4 to protect the circuit from overload.

[0052] Specifically, the circuit protector 9 is arranged between the timer 3 and the power supply 4 to monitor and control the current before it is output from the power supply 4 to the timer 3. When the charging current exceeds the set safety threshold, the circuit protector 9 will automatically cut off the power supply 4 to prevent the circuit from overloading, thereby avoiding possible electrical fires or equipment damage.

[0053] The circuit protector 9 can also provide short-circuit protection. When a short circuit is detected in the circuit, the circuit protector 9 will quickly cut off the power supply 4 to prevent the damage caused by the short circuit.

[0054] In some embodiments, the wireless charging device for the wind turbine free-climbing device 1 further includes a fixing bracket, and the transmitting coil 7 is fixed to the crossbeam 12 at the bottom of the ladder 5 through the fixing bracket.

[0055] Specifically, the fixing bracket is made of a strong and insulating material, such as hard plastic, which can withstand various environmental conditions that may be encountered in daily use, including wind, temperature changes and physical impact, and provide stable support to prevent the transmitting coil 7 from accidentally moving or falling off, thereby avoiding charging interruption affecting use.

[0056] Securing the transmitting coil 7 to the crossbar 12 at the bottom of the ladder 5 using a mounting bracket secures the transmitting coil 7 in its specific position, ensuring a stable relative position relative to the receiving coil 6 and thus ensuring effective wireless charging. This mounting method also helps maintain the reliability and stability of the entire device over long-term use, minimizing the potential adverse effects of coil position fluctuations on the charging process.

[0057] In some embodiments, the above-mentioned fixed bracket includes a fixed plate 10 and a connecting rod 11, one end of the connecting rod 11 is fixedly connected to the fixed plate 10, and the other end is slidably connected to the crossbeam 12, and the transmitting coil 7 is fixed on the side of the fixed plate 10 close to the anti-climbing device 1.

[0058] Specifically, the combination of fixing plate 10 and connecting rod 11 provides more flexible and stable fixation of transmitting coil 7. The connecting rod 11 is slidably connected to the crossbeam 12, allowing for convenient adjustment of the position of transmitting coil 7 to improve charging efficiency. The sliding connection can be achieved by loosening bolts, sliding rails, or other adjustable structures.

[0059] The transmitting coil 7 is fixed on one side of the fixing plate 10, close to the anti-climbing device 1, which helps to shorten the distance between the transmitting coil 7 and the receiving coil 6, reduce energy transmission loss, and improve charging efficiency.

[0060] In some embodiments, a slide groove 13 is provided on the cross beam 12 , and a slider 14 is provided on one end of the connecting rod 11 close to the cross beam 12 . The connecting rod 11 and the cross beam 12 slide with each other through the slider 14 and the slide groove 13 .

[0061] Specifically, the slide groove 13 provides a stable track for the slider 14 on the connecting rod 11 to facilitate precise position adjustment; the size and shape of the slider 14 are adapted to the slide groove 13 to ensure smooth and stable sliding; the slider 14 is made of wear-resistant material to reduce wear and increase service life.

[0062] Through the cooperation between the slider 14 and the slide groove 13, the operator can quickly adjust the position of the transmitting coil 7 on site to optimize the charging efficiency or adapt to equipment updates.

[0063] In some embodiments, a plurality of clamping slots 15 matching the connecting rod 11 are provided at the opening of the sliding slot 13 , and the clamping slots 15 are used to clamp and fix the connecting rod 11 .

[0064] Specifically, the slots 15 are distributed along the length of the chute 13, each corresponding to a specific position on the connecting rod 11. The operator can secure the connecting rod 11 to different positions as needed. The slots 15 provide a stable fixing point for the connecting rod 11. Once the slider 14 of the connecting rod 11 is moved to the desired position, the slots 15 securely lock the connecting rod 11 in place, preventing displacement due to vibration or external forces.

[0065] The operator can easily unlock, adjust and re-fix the connecting rod 11 to adapt to different charging needs or environmental changes.

[0066] In some embodiments, the wireless charging device for the wind turbine anti-climbing device 1 further includes an adsorption component, which is a group of magnetic strips 16 , and the magnetic strips 16 are respectively arranged on the abutting surfaces of the battery 2 and the fixing plate 10 .

[0067] Specifically, the magnetic strip 16 helps ensure the precise alignment between the transmitting coil 7 and the receiving coil 6 to improve the efficiency of wireless charging; when the transmitting coil 7 and the receiving coil 6 are aligned, the loss during energy transmission is minimized, reducing the energy loss caused by improper alignment, thereby improving the charging efficiency.

[0068] The stable support provided by the magnetic strip 16 reduces coil displacement caused by vibration or external forces, and reduces overheating or circuit damage that may be caused by improper alignment. This improves the safety of the charging process and reduces the possibility of device damage.

[0069] In some embodiments, a heat dissipation hole 17 is formed on a side of the fixing plate 10 away from the transmitting coil 7 .

[0070] Specifically, the provision of heat dissipation holes 17 helps to dissipate the heat generated by the transmitting coil 7 during operation, preventing heat accumulation and overheating that could affect performance or cause malfunction. The provision of heat dissipation holes 17 can effectively improve the reliability and stability of charging, extend the service life, and ensure long-term stable operation of the entire charging process.

[0071] In some embodiments, the wireless charging device for the wind turbine anti-climbing device 1 further includes a charging indicator light 18 , which is connected to the transmitting coil 7 and the power supply 4 , respectively, for indicating the charging status.

[0072] Specifically, the charging indicator light 18 uses different colors of light or flashing patterns to indicate different charging states. For example, green may indicate charging is in progress, while red indicates charging is complete or interrupted. Operators can quickly understand the charging status without specialized equipment or complex operations. The intuitive indication can effectively reduce operational complexity and improve work efficiency.

[0073] Those skilled in the art will readily conceive of other implementations of the present application after considering the specification and practicing the technical solutions disclosed herein.

[0074] This application is intended to cover any modifications, uses or adaptations of the present application that follow the general principles of the present application and include common knowledge or customary technical means in the technical field that are not disclosed in this application.
