Description

Technical Field

[0001] The present invention relates to the technical field of wind turbines, and particularly to a lightweight wind turbine test device obtained from simulation technology. Background Art

[0002] The wind turbine floats the entire wind power generation device on the sea or lake through a floating device and uses the wind at sea for power generation. Before building the offshore wind power generation device, it is necessary to simulate the challenges encountered by the wind turbine generator set in the actual use scenario, such as the impact of the overall shaking on the generator set and the mutual displacement between the wind turbine generator sets caused by the beating of the waves. Only after passing the simulation test can the wind power generation device be placed on the sea for power generation. When facing the offshore environment, the salt content in the air is relatively high. When the salt adheres to the surface of the wind turbine generator set, the existing detection method is to place it in a box and spray a salt-containing solution to make the salt adhere to the surface of the generator set, and set up a camera to observe the corrosion condition of the shell. During this process, considering that the salt mist itself is not transparent, the camera is easily interfered by the salt mist during shooting and the shooting is not clear, which affects the judgment of the experimental data.

[0003] At the same time, when the salt mist in the box diffuses, the salt mist is easily adhered to the surface of the generator set. When the salt mist adheres to the surface, the area photographed by the camera is blocked by the salt mist, resulting in the inability to observe the corrosion condition of the surface of the generator set, and thus it is impossible to ensure whether the observed data is accurate. Summary of the Invention

[0004] In order to overcome the disadvantages that the existing camera is easily interfered by the salt mist during the real-time observation of the corrosion condition of the shell and the shooting is not clear, which affects the judgment of the experimental data, and at the same time, the salt mist adheres to the surface of the engine set and blocks the camera shooting, resulting in inaccurate experimental data, the present invention provides a lightweight wind turbine test device obtained from simulation technology.

[0005] The technical solution of the present invention is: a lightweight wind turbine test device obtained from simulation technology, including a detection box, a cover shell, a fan and a fixing plate; a storage pool is arranged inside the detection box; a circulation pump is arranged inside the storage pool; the cover shell is detachably connected to the detection box; a fan is arranged on the detection box; a fixing plate is installed inside the detection box; a transmission is placed on the fixing plate; it also includes a first arc plate, a spray pipe, a second arc plate, a first electric slide rail, an adjustment component and a scraper; two first electric slide rails are fixedly connected to the lower side of the cover shell; a first arc plate is fixedly connected to the lower side of each first electric slide rail; a plurality of spray pipes are fixedly connected to the opposite sides of the two first arc plates, and the spray pipes are connected to the circulation pump inside the storage pool; two second arc plates are fixedly connected to the cover shell, and a plurality of adjustment components for reducing the use of salt mist are connected to the two second arc plates together; the adjustment components are located between adjacent spray pipes; a plurality of scrapers for removing residual salt particles before observation are arranged on the adjustment components.

[0006] Further, the adjustment component includes a first baffle, a camera, a connecting plate, a second electric slide rail, a second baffle, an electric rotating rod and a sliding plate; a first baffle is slidably connected to the lower side of each second arc plate; a camera for monitoring the corrosion of the transmission housing is connected to the two first baffles together; two connecting plates are fixedly connected to the opposite sides of the two first baffles; and all the connecting plates are attached to the cover shell; two second electric slide rails are fixedly connected to each connecting plate; a sliding plate is fixedly connected to the moving parts of the two second electric slide rails on the same connecting plate together; each scraper is connected to the adjacent sliding plate; an electric rotating rod is arranged on each of the opposite sides of the two first baffles; a second baffle for preventing salt mist from floating upward is fixedly connected to the rotating part of each electric rotating rod, and the second baffles are arranged in a staggered up-and-down manner.

[0007] Further, each scraper is detachably connected to the adjacent sliding plate.

[0008] Further, a diversion groove is arranged on the inner side of each scraper.

[0009] Further, the upper side of the fixing plate is set to have an inclined upper surface.

[0010] Further, a sensor for detecting the salt water concentration in the storage pool is arranged on the fixing plate.

[0011] Further, the connection part between the fixing plate and the transmission is always below the liquid level of the storage pool in the detection box.

[0012] Further, an air outlet groove is opened on each second baffle, and each air outlet groove is connected to an external air pumping device.

[0013] Further, the lower side of the second baffle is made of an anti-adhesion material.

[0014] Further, the adjacent two second baffles are arranged in a curved arc shape.

[0015] The beneficial effects are as follows: The present invention realizes that through the obstruction of the scraping plate, the first baffle and the sliding plate, most of the salt spray cannot spread to the camera, reducing the interference of the salt spray on the camera and ensuring the real-time monitoring of the camera; The clear water is sprayed onto the surface of the transmission through the diversion groove arranged in the scraping plate, so that the salt adhered to the surface of the transmission is diluted and washed away, and then the surface of the transmission is exposed. Then, the corrosion condition of the transmission is observed through the camera, ensuring that the observed data is not interfered by salt; The upward floating salt spray is blocked by the closed second baffle. Since the lower side of the second baffle is made of anti-adhesion material, the salt spray contacts and condenses and drips on the lower side of the second baffle, further ensuring that there is no salt adhesion on the lower side of the camera; After the gas is ejected through the air outlet groove, an air curtain is formed, so that the camera is not polluted by the salt spray when observing the initial salt spray adhesion on the transmission, ensuring that the camera is always in a clean state for shooting and improving the accuracy of the detection data.

[0016] The test device of the present invention can also be composed of an accurate wind turbine model and a hardware-in-the-loop simulation test platform, which can simulate various wind conditions of the wind turbine in on-site operation, so as to comprehensively test the reliability and robustness of the control system, avoiding the situation of waiting for wind in on-site testing; moreover, it can "simulate and reproduce" the faults encountered in the actual operation of the wind turbine.

[0019] The preferred technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Embodiment 1

[0021] A lightweight wind turbine test device obtained from simulation technology, as Figures 1-6 shown, includes a detection box 1, a cover shell 2, a fan 3 and a fixed plate 6; a storage pool is arranged in the detection box 1; a circulating pump is arranged in the storage pool; the cover shell 2 is detachably connected to the detection box 1; a fan 3 is arranged on the detection box 1; a fixed plate 6 is installed in the detection box 1; a transmission 4 is placed on the fixed plate 6; It further includes a first arc plate 101, a spray pipe 102, a second arc plate 103, a first electric slide rail 107, an adjusting component and a scraper 5; two first electric slide rails 107 are fixedly connected to the lower side of the cover shell 2; a first arc plate 101 is fixedly connected to the lower side of each first electric slide rail 107; a plurality of spray pipes 102 are fixedly connected to the opposite sides of the two first arc plates 101, and the spray pipe 102 is connected to the circulating pump in the storage pool; two second arc plates 103 are fixedly connected to the cover shell 2, and a plurality of adjusting components are connected to the two second arc plates 103 together; the adjusting component is located between adjacent spray pipes 102; a plurality of scrapers 5 are arranged on the adjusting component.

[0022] The adjusting component includes a first baffle 104, a camera 105, a connecting plate 106, a second electric slide rail 109, a second baffle 108, an electric rotating rod 110 and a slide plate 111; a first baffle 104 is slidably connected to the lower side of each second arc plate 103; a camera 105 is connected to the two first baffles 104 together; two connecting plates 106 are fixedly connected to the opposite sides of the two first baffles 104; and all the connecting plates 106 are in contact with the cover shell 2; two second electric slide rails 109 are fixedly connected to each connecting plate 106; a slide plate 111 is fixedly connected to the moving parts of the two second electric slide rails 109 on the same connecting plate 106; each scraper 5 is connected to the adjacent slide plate 111; an electric rotating rod 110 is arranged on each of the opposite sides of the two first baffles 104; a second baffle 108 is fixedly connected to the rotating part of each electric rotating rod 110, and the second baffles 108 are arranged in a staggered up and down manner.

[0023] Each scraper 5 is detachably connected to the adjacent slide plate 111.

[0024] Each scraper 5 is provided with a diversion groove on the inner side. The diversion groove is externally connected to a water pump through a hose, and pure water is pumped to the scraper 5 through the water pump, making it easier to clean the salt on the transmission 4, and thus more conducive to observation.

[0025] The upper side of the fixing plate 6 is set to have an inclined upper surface, guiding the condensed salt mist to fall into the storage pool in the detection box 1, avoiding a large amount of salt mist sprayed by the spray pipe 102 accumulating on the fixing plate 6. While ensuring the recovery of salt mist, it prevents the position where the transmission 4 is fixedly connected to the fixing plate 6 from being immersed in the salt mist, affecting the judgment of the experiment.

[0026] A sensor for detecting the salt water concentration in the storage pool is provided on the fixing plate 6, facilitating adding water when the concentration is high and adding salt when the concentration is low.

[0027] The bolt connection between the fixing plate 6 and the transmission 4 is always below the liquid level of the storage pool in the detection box 1, facilitating the detection of the corrosion condition of the bolt connection of the transmission 4. At the same time, it avoids the precipitation of salt at this position, preventing the difficulty of disassembly caused by salt adhesion during later disassembly.

[0028] Before the simulation test of the actual use scenario of the transmission 4 at sea, the worker first removes the cover 2, then fixes the transmission 4 on the upper side of the fixing plate 6 with bolts, and then covers the cover 2 back on the detection box 1. By starting the external liquid pumping device to pump the salt-containing solution into the spray pipe 102, taking the front-to-back view as the reference, then starting the first electric slide rail 107 to drive the first arc plate 101 to rotate reciprocally clockwise and counterclockwise, atomizing the salt-containing solution through the spray pipe 102 and spraying it into the detection box 1, thereby simulating the operating condition of the transmission 4 under the corrosion of sea salt mist. At this time, the corrosion condition of the surface of the transmission 4 housing is observed in real time by using the camera 105, and then the data is recorded.

[0029] In the above process, in order to shorten the detection time, a high-humidity and high-salt environment is created by spraying salt mist through the uninterrupted spray pipe 102, accelerating the corrosion of the surface of the transmission 4 housing. Considering that the salt mist itself is not translucent, when a large amount of salt mist drifts in the detection box 1, the camera 105 placed under the cover 2 is interfered by the salt mist and it is difficult to capture the corrosion condition of the surface of the transmission 4 housing. This results in the camera 105 being unable to collect data. To avoid this phenomenon, the worker first inserts the scraper 5 onto the slide plate 111, so that the scraper 5, the first baffle 104 and the slide plate 111 cooperate to mask the camera 105, thereby isolating it from the spray pipe 102. The salt mist sprayed by the spray pipe 102 is blocked by the scraper 5, the first baffle 104 and the slide plate 111. It should be noted that: in the initial state, there is a certain distance between the scraper 5 and the surface of the transmission 4, so that most of the salt mist cannot spread to the camera 105, reducing the interference of the salt mist on the camera 105, ensuring that there is no large amount of salt mist drifting in the visible area of the camera 105, and thus ensuring that the camera 105 can observe the corrosion condition of the surface of the transmission 4.

[0030] At the same time, after the scraper 5 is added, a large amount of salt mist cannot spread to the masking area formed between the two scrapers 5, which results in uneven salt mist adhesion on the surface of the transmission 4, and there are different corrosion conditions on the surface of the transmission 4. To avoid the situation where the area of the transmission 4 masked by the scraper 5 and the slide plate 111 has poor salt mist adhesion, taking the front-to-back view as the reference, the first electric slide rail 107 is started to drive the first arc plate 101 to rotate reciprocally clockwise and counterclockwise, thereby driving the spray pipe 102 to spray salt mist along the surface of the transmission 4. At this time, the fan 3 is started to inject air into the detection box 1 to blow the surface of the transmission 4, so as to form uniform salt on the surface of the transmission 4, thus avoiding the situation of uneven salt adhesion on the surface of the transmission 4. At the same time, when the spray pipe 102 touches the scraper 5 during the rotation process, the spray pipe 102 synchronously drives the scraper 5 to move, and thus the scraper 5 drives the first baffle 104 to slide synchronously on the second arc plate 103. When the scraper 5 touches the camera 105, the scraper 5 also drives the camera 105 to slide together, thereby driving the camera 105 to photograph the transmission 4, increasing the observable range of the camera 105 and making the data observed by the camera 105 more comprehensive.

[0031] In the above process, considering that when salt adheres to the surface of the transmission 4, the adhesion of the salt causes the surface of the transmission 4 to be blocked. At this time, the camera 105 cannot observe the corrosion condition of the surface of the transmission 4 covered by the salt. After the salt corrodes the transmission 4 for a period of time, the second electric slide rail 109 is started to drive the slide plate 111 to move towards the surface of the transmission 4, so that the scraper 5 is attached to the surface of the transmission 4. The spray pipe 102 drives the scraper 5 to slide on the transmission 4, and then the bristles on the surface of the scraper 5 are used to scrape off the salt adhering to the surface of the transmission 4. At this time, the surface of the transmission 4 after the salt is scraped off is exposed, and then the corrosion condition of the transmission 4 is observed through the camera 105 to ensure that the observed data is not interfered by the salt. In this process, a closed space is formed between the scraper 5 and the transmission 4. While the salt spray is not stopped, the spray pipe 102 drives the movement of the camera 105, and then the corrosion condition of the surface of the transmission 4 is observed, improving the observation effect of the camera 105 on the transmission 4.

[0032] It is also considered that when the models of the detected transmissions 4 are different, the extension length of the slide plate 111 is adjusted according to the different sizes of the transmissions 4, so that the masking area formed by the slide plate 111 and the scraper 5 changes accordingly, and the area masked by the slide plate 111 and the scraper 5 always occupies a larger space inside the detection box 1. While not affecting the salt spray, the use of salt spray is reduced, ensuring environmental protection during salt spray detection. It is also considered that when salt spray detection needs to be carried out on different models of transmissions 4, the worker can also remove the scraper 5 from the slide plate 111 and then replace the scraper 5 that fits the surface of the transmission 4 to be detected and plug it on the slide plate 111, improving the self - adaptability of the device and making the device not limited to the detection of a single type of transmission 4.

[0033] Embodiment 2

[0034] On the basis of Embodiment 1, as Figure 1 、 Figure 6 and Figure 7 shown, each second baffle 108 is provided with an air outlet groove 10801, and each air outlet groove 10801 is connected to an external air - pumping device.

[0035] The lower side of the second baffle 108 is made of an anti - adhesion material to prevent a large amount of salt spray from accumulating on the second baffle 108, ensuring the cleanliness of the second baffle 108 and avoiding the accumulation of salt spray on the second baffle 108 from hindering the observation of the camera 105.

[0036] Two adjacent second baffles 108 are arranged in a curved arc shape. After the slide plate 111 extends and adjusts and approaches the transmission 4, the space gradually becomes smaller. At this time, the two second baffles 108 are overlapped and closed in a staggered manner to ensure the salt spray interception ability.

[0037] It is also considered that when there is a gap between the transmission 4 and the scraper 5, in order to prevent the salt mist from floating upward and adhering to the surface of the camera 105, two electric rotating rods 110 are activated to overlap the two second baffles 108, and then cooperate with the first baffle 104 and the sliding plate 111 to place the camera 105 in a sealed environment, thereby intercepting the salt mist and preventing it from floating towards the camera 105, ensuring that there is no salt mist adhering to the camera 105 and avoiding salt mist interfering with the normal shooting of the camera 105. During this process, when the camera 105 needs to observe the salt mist adhesion on the surface of the transmission 4 in the early stage, the two electric rotating rods 110 are controlled to open the second baffle 108 downward, so that the camera 105 can observe the salt mist adhesion on the surface of the transmission 4 and the initial data before the transmission 4 is corroded. During this process, since the transmission 4 is in the state of salt mist adhesion in the early stage, it is easy to damage the formation of the salt mist on the surface of the transmission 4 by pressing the scraper 5 against the surface of the transmission 4. After the second baffle 108 is opened, when the salt mist diffuses in the detection box 1, it is easy to cross the second baffle 108 and directly contact the camera 105. To avoid this phenomenon, an external air pump device is used to inject gas into the air outlet groove 10801. Since the two second baffles 108 are both opened downward at this time, the gases ejected from the two air outlet grooves 10801 intersect with each other to form an air curtain, thereby blocking the salt mist and preventing it from flowing towards the camera 105 across the air curtain, and thus avoiding the camera 105 being contaminated when observing the initial salt mist adhesion on the transmission 4.

Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited by the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
