Description

A photo recognition device for elevators inside wind turbine towers Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically a photo recognition device for a lifting machine inside a wind turbine tower. Background Technology

[0002] As a crucial component of renewable energy, wind power generation relies on its core equipment—the wind turbine tower (also known as a wind tower)—which typically reaches heights of tens to hundreds of meters. These towering structures not only withstand complex dynamic loads (such as strong winds and earthquakes) but also require regular maintenance and repairs. Due to the narrow internal space and large vertical height of the tower, traditional methods relying on climbing or simple suspended platforms present safety hazards and inefficiencies. Therefore, tower hoisting platforms have emerged. This equipment operates precisely along guide rails via an electric drive system, enabling technicians to work at designated heights, significantly improving maintenance efficiency and safety. Simultaneously, the equipment can be equipped with high-definition cameras and image processing modules, dynamically capturing the structural features, equipment status, and personnel operation scenarios inside the tower during the hoisting process. Combined with AI algorithms, it automatically identifies potential defects (such as cracks and corrosion) or violations (such as not wearing safety equipment) and transmits image data to the control center in real time, achieving photo recognition functionality.

[0003] For example, patent application CN 220549882 U discloses a tower hoist fixing mechanism, relating to the field of hoisting equipment technology. It includes a fixed slide and a guide wheel assembly. The guide wheel assembly is connected to the car and slidably connected to the fixed slide. The guide wheel assembly includes rollers, which are slidably connected to the fixed slide. Each roller has an oil reservoir inside and an oil outlet on its outer surface, which communicates with the oil reservoir. In this application, the oil reservoir squeezes out lubricating oil to lubricate the guide wheel when the roller is compressed, reducing wear and tear on the rollers and fixed pulleys during operation. The fixing mechanism of this application makes the wind turbine tower hoist work more stably.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found:

[0005] Although this tower hoist fixing mechanism can reduce the wear and tear on the rollers and fixed pulleys, during use, the hoist equipment is prone to slight vibrations due to inertia during the opening phase. As the number of people in the car increases, the load and vibration amplitude will increase significantly. Such continuous micro-vibrations not only accelerate the fatigue wear of the braking components, but also more easily cause long-term accumulated safety hazards, affecting the overall operational reliability of the system. Summary of the Invention

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a photo recognition device for a wind turbine tower elevator, which has the advantage of assisted positioning. It solves the problem that the elevator equipment is prone to slight vibrations due to inertia during the opening phase, and as the number of people in the car increases, the load and vibration amplitude will increase significantly. Such continuous micro-vibrations not only accelerate the fatigue wear of the braking components, but also easily cause long-term accumulated safety hazards, affecting the overall operational reliability of the system.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wind turbine tower elevator photo recognition device, comprising a car and a fixed slide, wherein the fixed slide is located on the front side of the car, the front side of the car is provided with a movable groove, the bottom of the inner wall of the car is rotatably connected to two movable frames by axle pins, the end of the movable frame away from the car is provided with a positioning rod, and the inner wall of the fixed slide is symmetrically provided with two positioning holes.

[0008] In a preferred embodiment of this utility model, an inclined plate is fixedly connected to the end of the movable frame away from the positioning rod, two through holes are opened at the bottom of the inner wall of the car, and a movable column is provided at the top of the through holes, with the surface of the movable column fitting against the outer side of the inclined plate.

[0009] As a preferred embodiment of this utility model, a connecting plate is fixedly connected to the top of the movable column, and a push plate is slidably connected to the top of the connecting plate via a slide rail. A slot is provided on the front side of the inner wall of the car.

[0010] In a preferred embodiment of this invention, a connecting rod is fixedly connected to the bottom of the movable column, a fixing ring is fixedly connected to the surface of the connecting rod, a spring is fixedly connected to the top of the fixing ring, and the other end of the spring is fixedly connected to the bottom of the car.

[0011] In a preferred embodiment of this invention, the end of the movable frame away from the inclined plate is fixedly connected to an installation plate, the positioning rod is slidably mounted on the outside of the installation plate via a slide rail, and the inner wall of the positioning hole is rounded.

[0012] As a preferred embodiment of this utility model, a sliding plate is fixedly connected to the front side of the connecting plate, and a sliding groove is provided on the front side of the inner wall of the car, with the surface of the sliding plate slidably connected to the inner wall of the sliding groove.

[0013] As a preferred embodiment of this utility model, a limiting plate is fixedly connected to the rear side of the inclined plate, and the limiting plate is L-shaped.

[0014] As a preferred embodiment of this utility model, a door is movably installed on the right side of the car via a hinge, and a guide frame is fixedly installed on the front side of the car, with the inner wall of the guide frame slidably connected to the surface of the fixed slide.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, by setting up a movable groove, a movable frame, a positioning rod, and a positioning hole, allows the rear side of the movable frame to rotate around the pivot pin when swayed inward, causing the front side of the movable frame to move the positioning rod outward. When the positioning rod is inserted into the positioning hole, it can provide auxiliary positioning for the car, greatly reducing the vibration force generated by the car when starting.

[0017] 2. This utility model is designed with an inclined plate, a through hole, and a movable column. The movable column is thicker at the top and thinner at the bottom. When the movable column moves downward along the through hole, it can continuously squeeze the inclined plate, causing the inclined plate to swing the movable frame, which in turn can drive the positioning rod to insert into the positioning hole.

[0018] 3. By setting a connecting plate, a push plate and a slot, the present invention can simultaneously drive two movable columns to move when the connecting plate is pressed down. When the push plate is flush with the slot, the connecting plate and the movable column can be temporarily limited by pushing the push plate into the slot, thereby preventing the positioning rod from dislodging from the positioning hole.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] As shown in Figures 1 to 4, the present invention provides a wind turbine tower elevator photo recognition device, including a car 1 and a fixed slide 2. The fixed slide 2 is located on the front side of the car 1. A movable groove 3 is provided on the front side of the car 1. Two movable frames 4 are rotatably connected to the bottom of the inner wall of the car 1 through a pivot pin. A positioning rod 5 is provided at the end of the movable frame 4 away from the car 1. Two positioning holes 6 are symmetrically opened on the inner wall of the fixed slide 2.

[0026] An inclined plate 7 is fixedly connected to the end of the movable frame 4 away from the positioning rod 5. Two through holes 8 are opened at the bottom of the inner wall of the car 1. A movable column 9 is set at the top of the through holes 8. The surface of the movable column 9 is in contact with the outer side of the inclined plate 7.

[0027] A connecting rod 13 is fixedly connected to the bottom of the movable column 9. A fixing ring 14 is fixedly connected to the surface of the connecting rod 13. A spring 15 is fixedly connected to the top of the fixing ring 14. The other end of the spring 15 is fixedly connected to the bottom of the car 1.

[0028] The movable frame 4 is fixedly connected to the mounting plate 16 at the end away from the inclined plate 7. The positioning rod 5 is slidably mounted on the outside of the mounting plate 16 via the slide rail. The inner wall of the positioning hole 6 is rounded.

[0029] By sliding the positioning rod 5 and rounding the corners of the positioning hole 6, the fault tolerance rate when the positioning rod 5 is inserted into the positioning hole 6 can be greatly improved.

[0030] In addition, a sliding plate 17 is fixedly connected to the front side of the connecting plate 10, and a groove 18 is provided on the front side of the inner wall of the car 1. The surface of the sliding plate 17 is slidably connected to the inner wall of the groove 18.

[0031] A connecting plate 10 is fixedly connected to the top of the movable column 9, and a push plate 11 is slidably connected to the top of the connecting plate 10 via a slide rail. A slot 12 is provided on the front side of the inner wall of the car 1.

[0032] The sliding plate 17 and the slide 18 enable the connecting plate 10 to drive the two movable columns 9 to rise and fall stably, making it easy for the push plate 11 to move and align with the slot 12.

[0033] Furthermore, a limiting plate 19 is fixedly connected to the rear side of the inclined plate 7. The limiting plate 19 is L-shaped and can prevent the movable column 9 from separating from the inclined plate 7 during movement.

[0034] A door 20 is installed on the right side of the car 1 via a hinge. A guide frame 21 is fixedly installed on the front side of the car 1. The inner wall of the guide frame 21 is slidably connected to the surface of the fixed slide 2. A pulley is installed on the side of the guide frame 21 that is in contact with the surface of the fixed slide 2, which can improve the stability of the car 1 as it rises and falls along the surface of the fixed slide 2.

[0035] The working principle and usage process of this utility model are as follows: When the car 1 stops moving on the surface of the fixed slide 2, the connecting plate 10 can be pressed down, causing the connecting plate 10 to drive the two movable columns 9 to move downward. At this time, the movable columns 9 can squeeze the inclined plate 7, causing the inclined plate 7 to drive the movable frame 4 to swing. The swing of the movable frame 4 can drive the mounting plate 16 and the positioning rod 5 to swing towards the sides of the fixed slide 2. When the connecting plate 10 drives the sliding plate 17 to slide downward to the maximum extent, the positioning rod 5 is inserted into the positioning hole 6. At the same time, the push plate 11 is flush with the slot 12. By pushing the push plate 11 into the slot 12, the connecting plate 10, movable columns 9, inclined plate 7, movable frame 4 and positioning rod 5 can be positioned to prevent movement. At this time, the positioning rod 5 can play an auxiliary positioning role for the car 1, thereby greatly reducing the vibration and friction loss generated by the car 1 when starting.

[0036] Simultaneously, when the movable column 9 moves downward, it can drive the connecting rod 13 and the fixed ring 14 to move downward, causing the fixed ring 14 to stretch the spring 15. When the car 1 needs to be raised or lowered again, the power module can be activated first through the microcontroller, but the brake is kept closed to prevent accidental slippage. Then, the push plate 11 is pulled out from the slot 12. At this time, the spring 15 contracts, which can drive the fixed ring 14, the connecting rod 13 and the movable column 9 to move upward back to their original positions. At this time, the squeezing and limiting effect of the movable column 9 on the inclined plate 7 and the movable frame 4 is released. By swinging the movable frame 4 in the opposite direction, the positioning rod 5 can be driven to disengage from the positioning hole 6. At this time, the controller can then execute the raising or lowering command on the car 1.
