Description

Technical Field

[0001] This invention relates to the field of corrosion resistance testing technology, and in particular to a corrosion resistance testing device for wind turbine busbars. Background Technology

[0002] The corrosion resistance testing device for wind turbine busbars integrates corrosion environment simulation, sample clamping, parameter monitoring, and data acquisition modules. It can accurately replicate complex corrosion conditions such as salt spray, damp heat, and acid and alkali in wind power sites, stably complete long-term corrosion resistance testing of busbar samples, and record corrosion changes and various performance data in real time. It has high testing accuracy and strong applicability, and can provide reliable test basis for wind turbine busbar material selection, anti-corrosion process optimization, and product quality inspection.

[0003] Existing corrosion resistance testing equipment for wind turbine busbars typically utilizes salt spray chambers. However, after the test, the samples need to be rinsed with water using a tap, the water droplets shaken off, and then the samples stored under normal conditions for a period of time for visual inspection to check for rust and cracks. Current technology requires manual removal of the samples and rinsing with a tap. This entirely manual process is not only cumbersome but also prone to inconsistencies in rinsing and water control due to human error, affecting the accuracy of the test results.

[0004] In summary, the existing technology lacks a technique for automatic rinsing of wind turbine busbars after salt spray testing. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the prior art by proposing a corrosion resistance testing device for wind power pipeline busbars.

The system includes a fixed connection, with one end of the U-shaped tube extending through the inner wall of the rinsing tank to the outside and fixedly connected to a pipe joint. The rinsing assembly also includes a threaded rod, both ends of which are rotatably connected to the inner wall of the rinsing tank. One end of the threaded rod extends through the inner wall of the rinsing tank to the outside and is fixedly connected to a second motor, which is fixedly connected to the outer wall of the rinsing tank. A movable block is threadedly connected to the outer wall of the threaded rod, and the movable block is slidably fitted with the outer wall of the bottom end of the U-shaped tube. The top end of the movable block is fixedly connected to the bottom end of the movable rinsing tube. Both ends of the threaded rod are fixedly connected to pulleys. The transmission assembly includes a belt, which is located in the inner walls at both ends of the rinsing tank. One end of the belt is frictionally driven with the pulley on the outer wall of the threaded rod, and the other end of the belt, which is frictionally driven with the pulley, extends through the inner wall of the rinsing tank to the outside and is fixedly connected to a transmission wheel.

[0007] Preferably, the movable frame is arranged in an L-shape, with a lead screw threaded through the bottom end of the movable frame. The lead screw is rotatably connected to the fixed frame. A motor is fixedly connected to one end of the lead screw, and the motor is fixedly connected to the fixed frame. A gear frame is fixedly connected to one end of the movable frame. The inner wall of the gear frame has a linear structure with multiple adjusting teeth rotatably connected to it. A spring is fixedly connected between the adjusting teeth and the inner wall of the gear frame.

[0008] Preferably, the wire taking assembly includes an electric push rod, which is fixedly connected to the movable frame. The output end of the electric push rod is fixedly connected to a movable cover. The bottom end of the movable cover is adapted to the top opening of the rinsing box. The bottom end of the movable cover has two positioning blocks fixedly connected in a symmetrical structure. The bottom end of the positioning blocks is slidably fitted with an opening plate.

[0009] Preferably, an arc-shaped rack is fixedly connected to one side of the open plate, and electric actuators are fixedly connected to the inner walls on both sides of the opening of the open plate. A V-shaped clamp is fixedly connected to the output end of the electric actuators. Gear shafts are meshed and driven on both sides of the arc-shaped rack, and the gear shafts are rotatably connected to the bottom end of the movable cover.

[0010] Preferably, a discharge pipe is fixedly connected through the bottom side wall of the rinsing tank.

[0011] Preferably, the transmission wheel is configured to mesh with the gear shaft for transmission.

[0012] Preferably, the pipeline placement assembly includes a rotating frame, the two ends of which are rotatably connected to the outer wall of one side of the flushing tank. The rotating frame is arranged in an I-shape, and multiple cable placement ends are rotatably connected to the inner sides of both ends of the rotating frame in a ring structure.

[0014] Compared with the prior art, the present invention has the following beneficial effects: By setting up a rinsing component in the rinsing chamber, after the wind power duct busbar tested in the salt spray test chamber is placed in the rinsing chamber by the wire taking component, the two ends of the wire can be rinsed using a U-shaped tube. At the same time, under the action of the threaded rod, the moving rinsing tube can be moved to achieve full-range automatic cleaning of the sample, replacing manual operation, simplifying the process, improving efficiency, and ensuring uniform rinsing effect, effectively guaranteeing the accuracy and consistency of test results. By setting up a transmission component, while the wire taking component places the tested wind turbine busbar into the rinsing box for rinsing, the transmission component can drive the tested wind turbine busbar to rotate under the drive of the rinsing component. This allows the sample surface to be rinsed more thoroughly and evenly during rinsing, completely removing residual corrosive media and further improving the rinsing quality. No manual intervention is required, which not only improves work efficiency but also ensures that the rinsing effect of each batch of samples is consistent, ensuring that the test data is accurate and reliable. By setting up a pipeline placement component, when the moving frame moves the flushed wind power pipeline busbar above the pipeline placement component, multiple samples can be placed using multiple placement ends. At the same time, the adjusting teeth on the moving frame can automatically drive the pipeline placement component to rotate intermittently, which can complete the static drying of the samples in an orderly manner. This not only improves the sample storage capacity and processing efficiency, but also makes the sample drying more uniform. Attached Figure Description

Detailed Implementation

[0017] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0018] like Figures 1-9The device shown is a corrosion resistance testing device for wind turbine busbars, comprising a salt spray test chamber 1, a fixed frame 2 fixedly connected to the outside of the salt spray test chamber 1, a movable frame 3 slidably mounted on the fixed frame 2, a wire take-up assembly 4 fixedly connected to the movable frame 3, a rinsing box 5 fixedly connected to one end of the fixed frame 2, a rinsing assembly 6 rotatably connected to the inner wall of the rinsing box 5, transmission assemblies 7 on both sides of the inner wall of the rinsing box 5, and a pipeline placement assembly 8 rotatably connected to the outside of the rinsing box 5. The rinsing assembly 6 includes a U-shaped tube 601, which is fixedly connected to the inner wall of the rinsing box 5. Nozzles are fixedly connected to both ends of the U-shaped tube 601. A movable rinsing pipe 602 is slidably mounted at the bottom end of the U-shaped tube 601. A flexible hose 603 is fixedly connected through one side of the movable rinsing pipe 602, and the other end of the flexible hose 603 is fixedly connected through one end of the U-shaped tube 601. One end of the U-shaped tube 601 passes through the inner wall of the rinsing box 5. The flushing assembly 6 also includes a threaded rod 605, with both ends of the threaded rod 605 rotatably connected to the inner wall of the flushing tank 5. One end of the threaded rod 605 extends through the inner wall of the flushing tank 5 to the outside and is fixedly connected to a motor 606. The motor 606 is fixedly connected to the outer wall of the flushing tank 5. A movable block 607 is threadedly connected to the outer wall of the threaded rod 605. The movable block 607 is slidably fitted with the outer wall of the bottom end of the U-shaped tube 601. The top end of the movable block 607 is fixedly connected to the bottom end of the movable flushing pipe 602. Both ends of the threaded rod 605 are fixedly connected to pulleys. The transmission assembly 7 includes a belt 701, which is located in the inner wall of both ends of the flushing tank 5. One end of the belt 701 is frictionally driven with the pulley on the outer wall of the threaded rod 605. The other end of the belt 701, which is frictionally driven with the pulley, extends through the inner wall of the flushing tank 5 to the outside and is fixedly connected to a transmission wheel 702. The salt spray test chamber 1 is equipped with multiple sets of intelligent sensors, including temperature sensors, humidity sensors, salt spray concentration sensors, and pressure sensors. All types of intelligent sensors are fixedly installed in different test areas inside the salt spray test chamber 1 by brackets, which can collect environmental parameters in all directions during the corrosion resistance test of wind power pipeline busbars.

[0019] By setting up a rinsing component 6 inside the rinsing box 5, after the test wind power duct busbar is placed inside the rinsing box 5 by the wire taking component 4, the two ends of the wire can be rinsed using the U-shaped tube 601. At the same time, under the action of the threaded rod 605, the movable rinsing tube 602 can be moved to achieve all-round automatic cleaning of the sample, replacing manual operation, simplifying the process, improving efficiency, and ensuring uniform rinsing effect, effectively guaranteeing the accuracy and consistency of the test results.

[0020] like Figure 4As shown, the movable frame 3 is arranged in an L-shape. A lead screw 301 is threaded through the bottom of the movable frame 3. The lead screw 301 is rotatably connected to the fixed frame 2. A motor 302 is fixedly connected to one end of the lead screw 301. The motor 302 is fixedly connected to the fixed frame 2. A gear frame is fixedly connected to one end of the movable frame 3. Multiple adjusting teeth 303 are rotatably connected to the inner wall of the gear frame in a linear structure. A spring 304 is fixedly connected between the adjusting teeth 303 and the inner wall of the gear frame.

[0021] Spring 304 enables the adjusting gear 303 to rotate the pipeline placement assembly 8 as the moving frame 3 moves above the pipeline placement assembly 8; the L-shaped moving frame 3 has high space utilization and can move above the salt spray test chamber 1 and the rinsing chamber 5, adapting to the sample transfer stroke.

[0022] like Figure 5 As shown, the wire taking assembly 4 includes an electric push rod 401, which is fixedly connected to the movable frame 3. A movable cover 402 is fixedly connected to the output end of the electric push rod 401. The bottom end of the movable cover 402 is adapted to the top opening of the rinsing box 5. Two positioning blocks 403 are fixedly connected to the bottom end of the movable cover 402 in a symmetrical structure. An opening plate 404 is slidably fitted at the bottom end of the positioning block 403.

[0023] The electric actuator 401 is the lifting drive component of the wire taking assembly 4, which can precisely drive the movable cover 402 to rise and fall vertically, realizing the sample lowering and material taking, lifting and transfer; the movable cover 402 can completely block the top opening of the rinsing box 5, so that the cavity is sealed during the rinsing operation, preventing water splashing and ensuring a clean working environment; the positioning block 403 is the rotation limit structure of the opening plate 404, ensuring that the opening plate 404 rotates smoothly and providing a precise support benchmark for sample clamping and angle adjustment.

[0024] An arc-shaped rack 405 is fixedly connected to one side of the open plate 404. Electric actuators 406 are fixedly connected to the inner walls on both sides of the opening of the open plate 404. A V-shaped clamp 407 is fixedly connected to the output end of the electric actuators 406. Gear shafts 408 are meshed and driven on both sides of the arc-shaped rack 405. The gear shafts 408 are rotatably connected to the bottom end of the movable cover 402.

[0025] Two sets of electric actuators 406 extend and retract synchronously, causing the V-shaped clamping plates 407 to move closer together. The V-shaped structure can adaptively clamp wind power pipe busbars of different diameters, providing stable clamping and strong adaptability. The arc-shaped rack 405 meshes with the gear shaft 408, which can drive the open plate 404 to rotate as a whole, thereby achieving precise self-rotation of the clamped busbar sample and providing structural support for the uniformity of rinsing.

[0026] like Figure 6 As shown, a discharge pipe 501 is fixedly connected through the bottom side wall of the rinsing tank 5.

[0027] Meanwhile, the rinsing tank 5 can be filled with water for soaking, and the discharge pipe 501 is a centralized discharge channel for rinsing wastewater, which can promptly discharge the sewage containing salt spray residue and corrosive impurities inside the rinsing tank 5.

[0028] After rinsing is completed, the rinsing component 6 stops spraying water, and the threaded rod 605 rotates and accelerates, which enables the busbar after rinsing to rotate and spin dry quickly, achieving rapid pre-drying, greatly shortening the subsequent static drying time, and improving the overall sample processing efficiency.

[0029] like Figure 8 As shown, the transmission wheel 702 is meshed with the gear shaft 408 for transmission.

[0030] The transmission wheel 702 meshes with the gear shaft 408, driving the arc-shaped rack 405 and the open plate 404 to rotate, ultimately achieving uniform self-rotation of the wind power pipe busbar sample in the clamped state.

[0031] like Figure 9 As shown, the pipeline placement assembly 8 includes a rotating frame 801. The two ends of the rotating frame 801 are rotatably connected to the outer wall of one side of the flushing tank 5. The rotating frame 801 is arranged in an I-shaped structure. Multiple cable placement ends 802 are rotatably connected to the inner sides of the two ends of the rotating frame 801 in a ring structure.

[0032] The bottom of the 802 wire-laying end is heavier than the top, and it always remains vertical under the center of gravity, thus keeping the sample horizontal.

[0033] One end of the rotating frame 801 is fixedly connected to a worm gear 803. A worm 804 is meshed and driven on one side of the worm gear 803. The worm 804 is rotatably connected to the flushing box 5. One end of the worm 804 is fixedly connected to a one-way wheel 805. The one-way wheel 805 is meshed and driven by the adjusting gear 303.

[0034] Working principle: First, after the wind turbine busbar sample completes the salt spray corrosion and weathering test for a set duration inside the salt spray test chamber 1, the chamber cover is opened, and the motor 302 drives the lead screw 301 to rotate, causing the moving frame 3 to slide horizontally along the fixed frame 2, precisely moving the wire taking component 4 above the salt spray test chamber 1; then, the electric push rod 401 extends, causing the movable cover 402 to descend, so that the open plate 404 approaches the sample, and the V-shaped clamping plates 407 are pushed together by the electric push rods 406 on both sides, firmly clamping the wind turbine busbar sample, completing the automatic material taking.

[0035] After the sample is picked up, the electric push rod 401 retracts and lifts the sample, and the motor 302 drives the lead screw 301 in the opposite direction, causing the moving frame 3 to slide and reset, accurately transferring the busbar sample after the corrosion test to the top of the rinsing box 5. Then the electric push rod 401 extends again and lowers the sample into the rinsing box 5. At the same time, the movable cover 402 seals the top opening of the rinsing box 5 to form a closed rinsing chamber, preventing rinsing water from splashing out and ensuring a clean working environment.

[0036] Then, a clean water source is connected to the pipe joint 604, and the water flows into the U-shaped pipe 601 and sprays out from the nozzles at both ends to perform targeted rinsing of both ends of the wind turbine busbar sample. At the same time, the motor 606 is started to drive the threaded rod 605 to rotate, which drives the moving block 607 and the moving rinsing pipe 602 to slide horizontally back and forth. With the help of the hose 603, water is supplied to the sample in all directions, and the middle and side walls are rinsed. During the rotation of the threaded rod 605, the transmission wheel 702 is driven to rotate through the pulleys and belts 701 at both ends. The transmission wheel 702 meshes with the gear shaft 408 and the arc-shaped rack 405 to rotate, which drives the open plate 404 and the clamped busbar sample to rotate at a uniform speed, so as to achieve uniform rinsing of the sample without dead angles, and thoroughly remove the residual salt spray corrosion medium on the surface. The rinsing wastewater is finally discharged through the bottom discharge pipe 501.

[0037] After the sample is rinsed, the external water supply is turned off and the water spraying stops; the motor 606 speeds up and drives the threaded rod 605 to rotate at high speed. The linkage transmission component 7 drives the sample to rotate rapidly. The centrifugal force generated by the high-speed rotation quickly removes the residual water droplets attached to the sample surface, completing the pre-drying treatment of the sample, greatly reducing the surface moisture content and shortening the subsequent static drying time.

[0038] After spin-drying, the electric push rod 401 lifts the sample, and the moving frame 3 slides again to transfer the rinsed and spin-dried busbar sample to the pipeline placement assembly 8, and places both ends of the sample on the wire release end 802. The wire release end 802 relies on its own weight to keep the center of gravity vertical, avoiding the sample tilting and water accumulation. During the translation of the moving frame 3, the adjusting gear 303 will drive the one-way wheel 805 to rotate in one direction, which will drive the worm gear 804 and worm wheel 803 to drive the rotating frame 801 to rotate intermittently, realizing the orderly exchange of multiple sets of wire release ends 802, which is convenient for placing the next sample. After the sample is dried, its appearance is inspected.
