Description

Technical Field

[0001] This utility model relates to the field of surveillance camera technology, and in particular to a surveillance camera for wind turbine generator sets. Background Technology

[0002] Wind energy is a new energy source with great potential. The principle of wind power generation is to use wind power to drive the blades of a wind turbine to rotate, and then use a speed increaser to increase the rotational speed of the blade output end, thereby causing the generator to generate electricity. When a wind turbine is generating electricity, the rotation and appearance of its blades can reflect the operating status of the wind turbine. Therefore, monitoring cameras are usually installed on the outside of the wind turbine nacelle to monitor the operation of the blades. However, in actual use, when encountering rain or snow, rain and snow can easily cover the surface of the lens of the video monitoring device. In addition, after a long period of use, dust carried by the airflow will also adhere to the surface of the lens. Such situations seriously affect the normal use of the monitoring camera and reduce the shooting effect of the monitoring camera.

[0003] In conclusion, developing a monitoring device that reduces external influences and can automatically clean the lens surface is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a monitoring camera for wind turbine generator sets, which solves the technical problem that existing monitoring camera lenses are easily affected by the external environment, resulting in unclear monitoring images.

[0005] To achieve the above objectives, this utility model provides a monitoring camera for wind turbine generator sets, comprising:

[0006] The protective cover is located above the camera body and extends to the outside of the camera body. The protective cover is used to protect the lens of the camera body. The protective cover can slide relative to the camera body. The inner wall of the protective cover is hinged with a scraper by a push rod. The scraper abuts against the lens. When the protective cover slides axially, the push rod pushes the scraper to scrape the lens.

[0007] The drive mechanism is connected to the protective cover plate and is used to drive the protective cover plate to slide.

[0008] Preferably, the camera body has four fixed protrusions at one end near the lens, and a guide rod is connected between each two fixed protrusions. The guide rods are parallel to each other, and the two ends of the scraper are slidably connected to each guide rod.

[0009] Preferably, the push rod is hinged at the midpoint of the scraper, and both ends of the scraper are connected to bending plates. The bending plates are L-shaped, and each bending plate bends away from the push rod. The bent part of each bending plate passes through each guide rod.

[0010] Preferably, the driving mechanism includes a driving component, which is located at the end of the camera body away from the lens. The output end of the driving component is connected to two first linkage rods. The driving component is used to drive the first linkage rods to rotate, and each first linkage rod rotates in a direction away from each other. A second linkage rod is hinged to the end of the first linkage rod away from the driving component, and the second linkage rod is connected to the protective cover plate.

[0011] Preferably, the output end of the drive component is provided with a drive worm gear, and two transmission gears are rotatably connected to the side wall of the camera body. Each transmission gear meshes with the drive worm gear, and the transmission gears are fixedly connected to the first linkage rod.

[0012] Preferably, the protective cover is provided with a connecting plate near the drive component port. The connecting plate is semi-circular and fits against the outer wall of the camera body. The second linkage rod is fixed to the connecting plate through a connecting bracket.

[0013] Preferably, the outer wall of the camera body is provided with guide grooves on both sides, the extension direction of the guide grooves is consistent with the length extension direction of the camera body, and the inner wall of the protective cover is provided with a slider, which engages with the guide groove.

[0014] Preferably, both the protective cover and the scraper are provided with mating grooves, and both ends of the push rod extend into each mating groove, with a hinge pin passing through each mating groove and the push rod.

[0015] Preferably, the camera body is equipped with a mounting bracket, which is fixed to the wind turbine generator set by mounting bolts.

[0016] Preferably, the mounting bracket includes a connecting part and a supporting part. The connecting part extends to a mounting plate, which is used to install mounting bolts. The supporting part is used to support the camera body. The supporting part and the camera body, as well as the connecting part and the supporting part, are rotatably connected with each other and the rotation axis is perpendicular.

[0017] Compared to the aforementioned background technology, the wind turbine generator monitoring camera provided by this utility model includes: a protective cover plate disposed on the outer periphery of the camera body, the protective cover plate being attached to the outer wall of the camera body, the protective cover plate being located on the side of the camera body where the lens is located, and partially extending to the outer side of the camera body, the protective cover plate being connected to a drive mechanism, the drive mechanism being used to drive the protective cover plate to slide along the axial direction of the camera body, a push rod being hinged to the inner side of the protective cover plate, and a scraper being hinged to the other end of the push rod, the scraper being attached to the lens of the camera body. During the monitoring of the operation of the wind turbine generator blades in this application, the protective cover plate located above the lens is used to shield against rain and snow, preventing rain and snow from adhering to the lens and affecting monitoring. After long-term use, when dust adheres to the lens, the drive mechanism pulls the protective cover plate, and the push rod disposed on the inner wall of the protective cover plate moves together. Since the other end of the push rod is connected to the scraper, the scraper abuts against the lens, the push rod rotates relative to the protective cover plate, and the scraper at the end of the push rod slides downward to scrape the lens, scraping off the dirt adhering to the lens surface, ensuring that the monitoring image of the monitoring camera is clear.

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] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] This utility model provides a monitoring camera for wind turbine generator sets. Please refer to the appendix of the instruction manual. Figure 1 With appendix Figure 2 This application includes a camera body 1 for observing the operation of wind turbine blades. A protective cover 4 is provided above the camera body 1. The protective cover 4 is located at the end of the camera body 1 where the lens is located, and the protective cover 4 extends to the outside of the camera body 1, so that the protective cover 4 can block rain, snow and other dirt falling from above the lens. A push rod 11 is hinged to the inner wall of the part of the protective cover 4 that extends to the outside of the camera body 1. The push rod 11 can swing inside the protective cover 4, and the rotation axis of the push rod 11 is perpendicular to the axis of the camera body 1. A scraper 9 is hinged to the other end of the push rod 11. The scraper 9 abuts against the lens surface. Furthermore, a drive mechanism 3 is provided on the side wall of the camera body 1. The drive mechanism 3 is connected to the protective cover 4 and can drive the protective cover 4 to slide along the axial direction of the camera body 1. During the monitoring of wind turbine blades using this application, the protective cover 4 extends to the outside of the camera body 1 to shield the lens, preventing rain and snow from adhering to the lens of the camera body 1. After a certain period of use, dust and other dirt blown by the airflow adhere to the lens surface, reducing the clarity of the monitoring results of the camera body 1. At this time, the drive mechanism 3 operates, pulling the protective cover 4 to slide, and the protective cover 4 extending to the outside of the camera body 1 retracts. The push rod 11 on the inner wall of the protective cover 4 swings accordingly. While the push rod 11 rotates, it pushes the scraper 9 to move downward. The scraper 9 scrapes the lens surface, removing the dirt adhering to the lens surface, keeping the lens clean, and enabling the camera body 1 to clearly capture the blade operation.

[0027] Please refer to the instruction manual appendix. Figure 2Four fixing protrusions 6 are provided at one end of the camera body 1 where the lens is located. Two fixing protrusions 6 are located on the inner wall of the protective cover plate 4, and the other two fixing protrusions 6 are located at the end of the outer shell of the camera body 1. A guide rod 7 is connected between the fixing protrusions 6 located inside the protective cover plate 4 and the fixing protrusions 6 located on the outer shell of the camera body 1. The two guide rods 7 are arranged in parallel. Furthermore, a bending plate 8 is connected to both ends of the scraper 9. The bending plate 8 is specifically L-shaped, and the bending direction of each bending plate 8 is opposite to each other. A guide rod 7 is inserted in the bending part of the bending plate 8. The guide rod 7 limits the sliding direction of the bending plate 8, so that the scraper 9 connected to the bending plate 8 slides in the specified direction, ensuring that the camera body 1 can monitor a clear image of the blade movement after the scraper 9 is cleaned.

[0028] Preferably, the inner wall of the protective cover plate 4 and the side wall of the scraper 9 are provided with mating grooves 10. The two ends of the push rod 11 extend into the mating grooves 10. A hinge pin is provided on the side wall of the mating groove 10. The hinge pin rotatably connects the push rod 11 to the mating groove 10. Preferably, the axis of the hinge pin is perpendicular to each guide rod 7. That is, when the protective cover plate 4 retracts, the plane swept by the push rod 11 is parallel to the two guide rods 7. This avoids the scraper 9 applying a force perpendicular to the guide rods 7 during the sliding process, which could easily cause deformation of the guide rods 7 and prevent the scraper 9 from accurately cleaning the dirt in the designated area of ​​the lens.

[0029] Please continue to refer to the instruction manual appendix. Figure 2 A connecting plate 5 is provided at the port of the protective cover plate 4. The connecting plate 5 is specifically a semi-circular plate. The protective cover plate 4 and the connecting plate 5 fit the camera body 1 between them. Furthermore, two sliders 401 are provided on the inner wall of the protective cover plate 4. The two sliders 401 are located at both ends of the diameter of the protective cover plate 4. Correspondingly, two guide grooves 101 are provided on the side wall of the camera body 1. The extension direction of each guide groove 101 is the axial direction of the camera body 1. After the protective cover plate 4 is attached to the camera body 1, each slider 401 engages with the guide groove 101. When the drive mechanism 3 pulls the protective cover plate 4, the sliders 401 located in the guide groove 101 slide away from the lens. Preferably, lubricating grease is applied between the sliders 401 and the guide groove 101 to prevent the sliders 401 and the guide groove 101 from aging due to the influence of the external environment, which would cause the drive mechanism 3 to be unable to pull the protective cover plate 4. In addition, the guide groove 101 restricts the movement direction of the protective cover plate 4 and also restricts the axial degree of freedom of the protective cover plate 4, preventing the protective cover plate 4 from rotating axially during sliding, reducing the effective area above the lens for blocking dirt, thereby reducing the protective effect of this application on the camera body 1.

[0030] Please refer to the instruction manual appendix. Figure 1 With appendix Figure 3The drive mechanism 3 is located below the camera body 1. The drive mechanism 3 includes a drive component 301, which is located at the end of the camera body 1 away from the lens. The rotation axis of the output end of the drive component 301 is parallel to the axis of the protective cover 4. A drive worm gear 302 is connected to the output end of the drive component 301. Two connecting shafts are vertically arranged on both sides of the drive worm gear 302, and each connecting shaft is fixed to the outer wall of the camera body 1. A transmission gear 303 is rotatably mounted on each connecting shaft, and each transmission gear 303 is connected to the drive worm gear 302 in a transmission connection. Please refer to the appendix of the instruction manual. Figure 4 The two transmission gears 303 are referred to as the first gear and the second gear, respectively. A bridge wheel 307 is connected between the first gear and the drive worm 302. The bridge wheel 307 is used to change the rotation direction of the first gear, so that the two transmission gears 303 meshing on the same drive worm 302 rotate in opposite directions. A first linkage rod 304 is fixedly connected to the end of the first gear and the second gear away from the camera body 1. A second linkage rod 305 is hinged to the end of the first linkage rod 304 away from the drive member 301. A connecting bracket 306 is provided at the end of the second linkage rod 305 away from the drive member 301. The connecting bracket 306 is fixed to the connecting plate 5. After the drive unit 301 is activated, the drive worm gear 302 drives the first gear and the second gear to rotate in opposite directions. The hinged ends of the first linkage rods 304 and the second linkage rods 305 move in opposite directions. During this process, the first linkage rods 304 and the second linkage rods 305 fold together. One end of the second linkage rod 305 fixed to the connecting plate 5 gradually approaches the drive unit 301. That is, the drive unit 301 pulls the protective cover plate 4 to move closer to the drive unit 301 through the linkage assembly composed of the first linkage rods 304 and the second linkage rods 305. The push rod 11 located inside the protective cover plate 4 drives the scraper 9 to clean the dirt on the lens surface.

[0031] Furthermore, in one embodiment of this application, the drive worm 302 may specifically be a left-right helical double-segment worm, that is, the helical directions of the front and rear segments of the drive worm 302 are opposite. Correspondingly, the first gear and the second gear are arranged sequentially along the axial direction of the drive worm 302. The helical directions of the worm teeth meshing with the first gear and the second gear are opposite. When the drive worm 302 rotates, the thrust applied by the worm teeth with different helical directions to the first gear and the second gear is opposite. The first linkage rods 304 connected to the first gear and the second gear rotate in opposite directions. The first linkage rods 304 and the second linkage rods 305 that are hinged to each other are folded. The second linkage rods 305 pull the protective cover plate 4 to move towards the side closer to the drive member 301, so that the protective cover plate 4 pushes the scraper 9 to remove the dirt attached to the lens.

[0032] Preferably, a laser sensor is provided inside the lens of the camera body 1. The laser sensor is connected to the drive unit 301. A laser emitter is provided on the housing of the camera body 1 located outside the lens. The laser signal of the laser emitter can be received by the laser sensor. After long-term use, some dirt adheres to the lens surface of the camera body 1. The dirt prevents the laser signal from entering the inside of the lens. When the laser intensity received by the laser sensor is lower than a preset value, the laser sensor sends an operation signal to the drive unit 301. The control component located inside the drive unit 301 receives the signal and controls the drive unit 301 to run. The protective cover plate 4 drives the scraper 9 to remove the dirt from the lens surface.

[0033] In addition, a mounting bracket 2 is provided below one end of the camera body 1 where the drive component 301 is located. The mounting bracket 2 includes a connecting part and a supporting part. The supporting part is used to connect the camera body 1, and the camera body 1 can rotate around the supporting part with the rotation axis perpendicular to the ground. The supporting part and the connecting part are hinged, that is, the supporting part and the connecting part can rotate relative to each other, and their rotation axes are perpendicular to each other. A mounting plate extends from the end of the connecting part, and mounting bolts are inserted in the mounting plate to fix the camera body 1 to the wind turbine generator set. The mounting bracket 2 with this structure allows the camera body 1 to shoot the blades from more angles.

[0034] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0035] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
