Description

Technical Field

[0001] This utility model relates to the field of rust removal device technology, specifically a rust removal device for the outer wall of a wind turbine tower based on a rotary sandblasting mechanism. Background Technology

[0002] Wind turbine towers are exposed to complex outdoor environments for extended periods, making their outer walls prone to corrosion. If corrosion continues to spread, it can lead to thinning of the tower's metal substrate, decreased mechanical properties, and even affect the overall structural stability of the tower, threatening the safe operation of the wind power equipment. This device, through its core rotating sandblasting mechanism, uses compressed air to propel abrasives such as diamond and quartz sand at high speed onto the tower's outer wall. Combined with the mechanism's rotation and the device's movement, it can quickly remove rust layers, oxide scale, and old coatings through an "impact + friction" process. Compared to manual sandblasting, its rotating mechanism allows for uniform and continuous operation, with a single unit typically covering a larger working area, significantly shortening the rust removal cycle and effectively preventing further damage to the tower from corrosion.

[0003] Because wind turbine towers are cylindrical, the position of the rust removal device needs to be adjusted when removing rust from different locations on the outer wall of the tower. In existing technologies, a snap-fit ​​structure is usually used to lock and fix the rust removal device after it is adjusted to the appropriate position. However, the snap-fit ​​locking force is limited in actual use, and snap-fit ​​connection operations at high altitudes pose certain safety hazards. Therefore, a new structure is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a rust removal device for the outer wall of wind turbine towers based on a rotary sandblasting mechanism, so as to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a rust removal device for the outer wall of a wind turbine tower based on a rotary sandblasting mechanism, comprising:

[0006] A quick-adjustable rust removal assembly includes a sandblasting machine, an L-shaped rod, a steel rail, a first S-shaped clamping rod, a second S-shaped clamping rod, a shaft, and an electro-hydraulic rod. The steel rail is movably connected to both sides of the outer wall of the wind turbine tower. One end of the L-shaped rod is movably connected to the middle of the steel rail, and the other end of the L-shaped rod is movably connected to the sandblasting machine. The steel rail is fixedly connected to one end of the first S-shaped clamping rod and one end of the second S-shaped clamping rod, respectively. The shaft is fixedly connected to the middle of the second S-shaped clamping rod, and the first S-shaped clamping rod is movably connected to the outer side of the shaft. The two ends of the electro-hydraulic rod are fixedly connected to the first S-shaped clamping rod and the second S-shaped clamping rod, respectively.

[0007] Furthermore, the side of the rail is configured with an arc-shaped structure.

[0008] Furthermore, the quick-adjusting rust removal assembly also includes a threaded groove, a motor, and a screw rod. The L-shaped rod has a threaded groove through it, the motor is fixedly connected to the rail, the output end of the motor is connected to the screw rod, and the screw rod is movably connected in the threaded groove.

[0009] Furthermore, the length of the rail is equal to the length of the screw rod.

[0010] Furthermore, it also includes a convenient and quick repair component, which includes a limiting block, a first slot, a second slot, and a plug rod. The limiting blocks are fixedly connected to both sides of the sandblasting machine. The first slot is opened through the limiting block, and the second slot is opened through the L-shaped rod. The L-shaped rod is movably connected between the limiting blocks, and the plug rod is movably connected between the first slot and the second slot.

[0011] Furthermore, the convenient and quick repair component also includes a receiving frame, a guide groove, a rectangular plate, and a spring. The receiving frame is fixedly connected to the L-shaped rod, and the guide groove is opened through the receiving frame. An insert rod is movably connected in the guide groove. The rectangular plate is fixedly connected to the outside of the insert rod, and a spring is movably sleeved on the outside of the insert rod.

[0012] Furthermore, the convenient and quick repair component also includes a long pull rod, which is fixedly connected at the top between the insert rods.

[0013] This utility model has the following beneficial effects:

[0014] This invention utilizes a lever linkage structure composed of a first S-shaped clamping rod, a second S-shaped clamping rod, and a shaft. Combined with the telescopic drive of an electric hydraulic rod, it enables the two steel rails to "actively clamp" the outer wall of the wind turbine tower. Compared to the passive locking of traditional clips, the electric hydraulic rod provides continuous and stable clamping force, and the fit between the steel rails and the outer wall of the cylindrical tower is higher. This prevents the device from shifting due to vibration or wind during operation, ensuring that the sandblasting machine is always aligned with the rust removal area, thus improving the uniformity of rust removal and operational safety.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-5 As shown, this utility model is a rust removal device for the outer wall of a wind turbine tower based on a rotary sandblasting mechanism, comprising:

[0027] The quick-adjustable rust removal assembly includes a sandblasting machine 101, an L-shaped rod 102, a steel rail 103, a first S-shaped clamping rod 104, a second S-shaped clamping rod 105, a shaft 106, and an electro-hydraulic rod 107. The steel rail 103 is movably connected to both sides of the outer wall of the wind turbine tower. One end of the L-shaped rod 102 is movably connected to the steel rail 103, and the other end of the L-shaped rod 102 is movably connected to the sandblasting machine 101. The steel rail 103 is fixedly connected to one end of the first S-shaped clamping rod 104 and the second S-shaped clamping rod 105, respectively. The shaft 106 is fixedly connected to the middle of the second S-shaped clamping rod 105, and the first S-shaped clamping rod 104 is movably connected to the outside of the shaft 106. The two ends of the electro-hydraulic rod 107 are fixedly connected to the first S-shaped clamping rod 104 and the second S-shaped clamping rod 105, respectively.

[0028] The sandblasting machine 101, model DS-108P, is used for rust removal. The L-shaped rod 102 is used to movably connect the sandblasting machine 101 and the steel rail 103. The first S-shaped clamping rod 104 and the second S-shaped clamping rod 105 are combined into a lever linkage structure through the shaft 106. The telescopic setting of the electric hydraulic rod 107 enables the first S-shaped clamping rod 104 and the second S-shaped clamping rod 105 to drive the two steel rails 103 to clamp and release on the outer wall of the wind turbine tower. This allows for quick locking after the first S-shaped clamping rod 104 and the second S-shaped clamping rod 105 are rotated and adjusted, and thus enables quick locking after the sandblasting machine 101 is adjusted to different positions on the outer wall of the wind turbine tower.

[0029] The side of rail 103 is designed with an arc-shaped structure.

[0030] The shape of the rail 103 ensures that it fits tightly against both sides of the outer wall of the wind turbine tower when under stress, thereby improving the clamping and fixing effect.

[0031] The quick-adjusting rust removal assembly also includes a threaded groove 108, a motor 109, and a screw rod 1010. The threaded groove 108 is opened through the L-shaped rod 102. The motor 109 is fixedly connected to the rail 103. The output end of the motor 109 is connected to the screw rod 1010. The screw rod 1010 is movably connected in the threaded groove 108.

[0032] The motor 109 provides kinetic energy for the rotation of the screw rod 1010. The screw rod 1010 and the threaded groove 108 work together to ensure the L-shaped rod 102 moves up and down along the wind turbine tower, thereby ensuring the up and down movement of the sandblasting machine 101.

[0033] The length of rail 103 is equal to the length of bolt rod 1010;

[0034] The dimensional settings between the aforementioned components ensure smooth movement of the sandblasting machine 101 along the rail 103.

[0035] Working principle: The device is moved to the location on the wind turbine tower to be derusted, so that the two arc-shaped steel rails 103 are respectively attached to the two sides of the outer wall of the wind turbine tower. At this time, the lever linkage structure formed by the first S-shaped clamping rod 104 and the second S-shaped clamping rod 105 through the shaft 106 is in the initial open state, ensuring that the steel rails 103 can smoothly fit against the outer wall of the tower. The electric hydraulic rod 107 is activated. When the electric hydraulic rod 107 retracts, it will generate a pulling force on the first S-shaped clamping rod 104 and the second S-shaped clamping rod 105. Since the shaft 106 is fixed to the first S-shaped clamping rod 104, the second S-shaped clamping rod 105 will be pulled. The second S-shaped clamping rod 105 is movably connected to the first S-shaped clamping rod 104 in the middle. Under the action of tension, the first S-shaped clamping rod 104 will rotate around the shaft 106, driving the two steel rails 103 to move synchronously towards the outer wall of the tower until the steel rails 103 tightly clamp the outer wall of the tower, completing the initial fixation of the device and preventing the device from shifting during subsequent rust removal operations. According to the height requirement of the area to be rusted on the outer wall of the tower, the motor 109 fixed on the steel rail 103 is started. The output end of the motor 109 drives the screw rod 1010 to rotate. Due to the L-shaped rod 102 The threaded groove 108 on the upper part is movably connected to the screw rod 1010, and the length of the rail 103 is equal to the length of the screw rod 1010. The rotation of the screw rod 1010 will be converted into the linear movement of the L-shaped rod 102 along the rail 103. The L-shaped rod 102 drives the sandblasting machine 101, which is movably connected to its other end, to move up and down synchronously until the sandblasting machine 101 reaches the target rust removal height. The sandblasting machine 101 (model DS-108P) is started, and compressed air is used to spray abrasive materials such as diamond abrasive and quartz sand at high speed onto the outer wall of the tower. During the rust removal process, if To remove rust from different circumferential locations on the tower, first extend the electric hydraulic rod 107 to loosen the rail 103 from the outer wall of the tower. Then, manually or via an auxiliary drive mechanism, rotate the entire device around the tower to a new rust removal position. Repeat the clamping and locking operation in step 2, and then continue sandblasting until the entire outer wall of the tower is rusted. After the rust removal operation is completed, first turn off the sandblasting machine 101, then start extending the electric hydraulic rod 107 to separate the rail 103 from the outer wall of the tower. Finally, remove the device from the tower to complete the entire operation.

[0036] Please see Figure 1-5 As shown, this embodiment, based on the above embodiment, further includes:

[0037] The convenient and quick repair component includes a limiting block 201, a first slot 202, a second slot 203, and a plug rod 204. The limiting blocks 201 are fixedly connected to both sides of the sandblasting machine 101. The first slot 202 is opened through the limiting block 201, and the second slot 203 is opened through the L-shaped rod 102. The L-shaped rod 102 is movably connected between the limiting blocks 201, and the plug rod 204 is movably connected between the first slot 202 and the second slot 203.

[0038] The limiting block 201 and the L-shaped rod 102 work together to ensure the initial disassembly and assembly of the sandblasting machine 101. The first slot 202, the second slot 203 and the insertion rod 204 work together to ensure the secure locking of the sandblasting machine 101.

[0039] The convenient and quick repair component also includes a support frame 205, a guide groove 206, a rectangular plate 207, and a spring 208. The support frame 205 is fixedly connected to the L-shaped rod 102. The guide groove 206 is opened through the support frame 205. The insertion rod 204 is movably connected in the guide groove 206. The rectangular plate 207 is fixedly connected to the outside of the insertion rod 204. The spring 208 is movably sleeved on the outside of the insertion rod 204. The spring 208 is located between the rectangular plate 207 and the support frame 205. The convenient and quick repair component also includes a long strip pull rod 209. The long strip pull rod 209 is fixedly connected to the top of the insertion rods 204.

[0040] The guide groove 206 on the receiving frame 205 ensures the limited sliding of the insertion rod 204. The rectangular plate 207 can limit the insertion range of the insertion rod 204. The spring 208 ensures that the insertion rod 204 is firmly inserted into the second slot 203 and the first slot 202. The long pull rod 209 makes it easy for the user to pull the insertion rod 204.

[0041] Working principle: The operator holds the long pull rod 209 and pulls it upward. The long pull rod 209 drives the two inserted rods 204 fixedly connected to it to move upward synchronously. The inserted rods 204 slide along the guide grooves 206 on the receiving frame 205. At this time, the rectangular plate 207 fixed on the outside of the inserted rod 204 will compress the spring 208 located between the rectangular plate 207 and the receiving frame 205 until the bottom of the inserted rod 204 is completely disengaged from the limit blocks 201 on both sides of the sandblasting machine 101. With the first slot 202 and the second slot 203 on the L-shaped rod 102 in the pulled-up state of the long rod 209, the sandblasting machine 101 is moved away from the L-shaped rod 102. Since the limiting block 201 and the L-shaped rod 102 are originally movably connected, after the insertion rod 204 is unlocked, the sandblasting machine 101 can be easily separated from the L-shaped rod 102. The sandblasting machine 101 can be removed for maintenance or replacement. By repeating the above process in reverse, the installation of the sandblasting machine 101 can be achieved.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
