Description

Technical Field

[0001] This utility model relates to the field of wind turbine tower weld inspection technology, and in particular to a wind turbine tower weld inspection robot with a telescopic support mechanism. Background Technology

[0002] As a key supporting structure of wind power generation systems, the stability and safety of wind turbine towers directly affect the normal operation of the entire system. During the manufacturing and installation of wind turbine towers, weld quality is a crucial factor affecting the structural strength of the tower. Because the tower bears various loads such as wind force and its own weight over long periods, defects in the welds, such as cracks and porosity, can lead to structural failure, causing serious safety accidents and significant economic losses.

[0003] With the continuous development of the wind power industry, the scale and height of wind turbine towers are constantly increasing, placing higher demands on the accuracy, comprehensiveness, and efficiency of weld inspection. Traditional inspection methods, such as manual inspection and some simple mechanical auxiliary inspection methods, are no longer sufficient to meet the needs of large-scale, high-specification wind turbine tower weld inspection. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a wind turbine tower weld inspection robot with a retractable support mechanism.

[0005] This utility model is achieved using the following technical solution: a wind turbine tower weld inspection robot with a retractable support mechanism, including a bottom fixed base, a support rod fixedly connected to the upper surface of the bottom fixed base, several sleeves sleeved on the outer surface of the support rod, a connecting block fixedly connected to the outer surface of the sleeve, a fixing ring fixedly connected to the inner wall of the connecting block, a positioning ring fixedly connected to the inner wall of the fixing ring, a sliding groove formed on the outer surface of the positioning ring, and several inspection robots fixedly connected to the outer surface of the sliding groove.

[0006] The above technical solution allows multiple inspection robots to be conveniently distributed at different heights around the tower, providing a basic structure for comprehensive inspection of tower welds. The retractable support mechanism can adapt to the inspection needs of wind turbine towers of different heights and diameters.

[0007] As a further improvement to the above solution, the inspection robot includes a moving block, the inner wall of which is rotatably connected to several moving wheels, and a motor is fixedly connected to the middle of the upper surface of the moving block. The output end of the motor is connected to the moving wheels via a belt pulley.

[0008] Through the above technical solution, the structure of motor and moving wheels enables the inspection robot to move autonomously around the tower weld, facilitating the inspection of welds at different locations and improving the flexibility and comprehensiveness of the inspection.

[0009] As a further improvement to the above solution, a connecting plate is fixedly connected to the front end of the moving block, a detection camera is fixedly connected to the middle of the front end of the connecting plate, and positioning support frames are fixedly connected to both sides of the front end of the connecting plate.

[0010] Through the above technical solutions, the inspection camera can intuitively acquire image information of the weld, so as to analyze and judge the weld quality in the future; the positioning support frame can improve the accuracy and stability of the inspection and protect the inspection equipment.

[0011] As a further improvement to the above solution, a top fixing seat is fixedly connected to the top of the support rod, and a lead screw is rotatably connected to one side of the lower surface of the top fixing seat, the lead screw being adapted to the sleeve.

[0012] The above technical solution provides a simple and effective design for the screw and sleeve structure, which can accurately control the height and position of the inspection robot, facilitating the inspection of welds at different heights of the tower.

[0013] As a further improvement to the above solution, a mounting base is fixedly connected to one side of the bottom fixing base, a motor is fixedly connected to the upper surface of the mounting base, and a first bevel gear is fixedly connected to the output end of the motor.

[0014] Through the above technical solution, the structure of the motor and the first bevel gear can provide power to the entire telescopic support mechanism, enabling the mechanism to work normally and facilitating operation and control.

[0015] As a further improvement to the above solution, a second bevel gear is fixedly connected to the bottom of the outer surface of the lead screw, and the second bevel gear is adapted to the first bevel gear.

[0016] Through the above technical solution, the bevel gear transmission structure can change the direction of power transmission, converting the horizontal rotation of the motor into the vertical rotation of the lead screw, thus realizing the effective transmission of power and ensuring the normal telescopic movement of the telescopic support mechanism.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model features a telescopic support mechanism consisting of a bottom fixed base, a support rod, and a sleeve. A motor drives a bevel gear to rotate a lead screw, which in turn moves the sleeve up and down along the support rod. This telescopic structure can adapt to wind turbine towers of different heights, allowing the inspection robot to reach different heights on the tower for weld inspection. This ensures that all welds on the entire tower can be inspected, improving the comprehensiveness of the inspection.

[0019] 2. This utility model enables the moving wheel of the inspection robot to move within the groove of the positioning ring by setting a motor in the moving block of the inspection robot, so that the inspection robot can move along the circumference of the tower. Multiple inspection robots are fixed on the positioning ring, which can inspect the tower from different circumferential positions, avoid inspection blind spots, and further enhance the comprehensiveness of the inspection.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Example:

[0029] Please combine Figure 1-5The wind turbine tower weld inspection robot with a telescopic support mechanism in this embodiment includes a bottom fixed base 1. A support rod 2 is fixedly connected to the upper surface of the bottom fixed base 1. Several sleeves 3 are sleeved on the outer surface of the support rod 2. A connecting block 4 is fixedly connected to the outer surface of the sleeve 3. A fixing ring 5 is fixedly connected to the inner wall of the connecting block 4. A positioning ring 6 is fixedly connected to the inner wall of the fixing ring 5. A groove 7 is opened on the outer surface of the positioning ring 6. Several inspection robots 8 are fixedly connected to the outer surface of the groove 7. The bottom fixed base 1 serves as the foundation of the entire structure. The support rod 2 on it provides support for the telescopic structure. The sleeves 3 are sleeved on the outer surface of the support rod 2 and can move up and down along the support rod 2. They are fixed by the connection of the connecting block 4, the fixing ring 5, the positioning ring 6, etc. The inspection robots 8 are fixedly connected to the groove 7 opened on the outer surface of the positioning ring 6, thereby positioning the inspection robots 8 at a suitable height and circumferential position.

[0030] The inspection robot 8 includes a movable block 801, with several movable wheels 802 rotatably connected to the inner wall of the movable block 801. A motor 803 is fixedly connected to the middle of the upper surface of the movable block 801. The output end of the motor 803 is connected to the movable wheels 802 via a belt pulley drive. Inside the inspection robot 8, the motor 803 rotates, driving the movable wheels 802 to rotate within the movable block 801 via the belt pulley drive. The movable wheels 802 can move within the groove 7 of the positioning ring 6, thereby enabling the inspection robot 8 to move along the circumference of the tower.

[0031] A connecting plate 804 is fixedly connected to the front end of the moving block 801. A detection camera 805 is fixedly connected to the middle of the front end of the connecting plate 804. Positioning support frames 806 are fixedly connected to both sides of the front end of the connecting plate 804. The detection camera 805 and the positioning support frames 806 are fixedly connected to the connecting plate 804 at the front end of the moving block 801. When the detection robot 8 moves to the position to be detected, the detection camera 805 can acquire images of the weld. The positioning support frame 806 may play a role in assisting positioning or protecting the detection camera 805.

[0032] The top of the support rod 2 is fixedly connected to a top fixing seat 9. A lead screw 13 is rotatably connected to one side of the lower surface of the top fixing seat 9. The lead screw 13 is adapted to the sleeve 3. When the lead screw 13 rotates, the sleeve 3 will move up and down along the lead screw 13, thereby realizing the telescopic function of the entire telescopic support mechanism.

[0033] A mounting base 10 is fixedly connected to one side of the bottom mounting base 1. A motor 11 is fixedly connected to the upper surface of the mounting base 10. A first bevel gear 12 is fixedly connected to the output end of the motor 11. The rotation of the motor 11 on the mounting base 10 drives the first bevel gear 12 to rotate. The motor 11 is the power source of the entire telescopic structure.

[0034] A second bevel gear 14 is fixedly connected to the bottom of the outer surface of the lead screw 13. The second bevel gear 14 is adapted to the first bevel gear 12. The motor 11 drives the first bevel gear 12 to rotate. The first bevel gear 12 is adapted to the second bevel gear 14 at the bottom of the outer surface of the lead screw 13, thereby transmitting the power of the motor 11 to the lead screw 13, causing the lead screw 13 to rotate.

[0035] Working principle: The motor 11 is mounted on the upper surface of the mounting base 10 on one side of the bottom fixed base 1. When the motor 11 starts, its output end drives the first bevel gear 12 to rotate. The first bevel gear 12 is matched with the second bevel gear 14 at the bottom of the outer surface of the lead screw 13. The rotation of the motor 11 transmits power to the lead screw 13 through the bevel gear transmission, causing the lead screw 13 to start rotating. Since the lead screw 13 is matched with the sleeve 3 sleeved on the outer surface of the support rod 2, the rotation of the lead screw 13 will cause the sleeve 3 to move up and down along the support rod 2. The top fixed base 9 and the bottom fixed base 1 are connected through the support rod 2 to form a stable frame structure. The up and down movement of the sleeve 3 realizes the height adjustment of the entire telescopic support mechanism. In the inspection robot 8, the motor 803 in the middle of the upper surface of the moving block 801 starts. The output end of the motor 803 is connected to the moving wheel 802 through the belt pulley transmission. Since the moving wheel 802 is rotatably connected to the inner wall of the moving block 801, when the motor 803 drives the moving wheel... When 802 rotates, the moving wheel 802 will roll in the groove 7 opened on the outer surface of the positioning ring 6. Because the inspection robot 8 is connected to the sleeve 3 through the connecting block 4, the fixing ring 5 and other structures, and is fixed on the groove 7 of the positioning ring 6, the rolling of the moving wheel 802 in the groove 7 will drive the entire inspection robot 8 to move along the circumference of the tower. When the inspection robot 8 moves to the vicinity of the tower weld, the inspection camera 805 fixedly connected to the middle of the front connecting plate 804 of the moving block 801 starts to work. The inspection camera 805 can collect images of the tower weld. The collected images can be used for subsequent analysis and judgment of the weld quality. The positioning support frame 806 on both sides of the front end of the connecting plate 804 may play a role in assisting in positioning the inspection camera 805, ensuring that the inspection camera 805 can accurately align with the weld for image collection. It may also play a certain protective role for the inspection camera 805, preventing it from being damaged by collisions during movement.

[0036] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
