Description

  The present invention relates to a failure prevention system for a wind power generation facility, for example, a failure prevention system for a wind power generation facility that prevents a failure of a generator provided inside a nacelle of the wind power generation facility.

  In recent years, there has been an increasing interest in wind power generation that uses natural power to generate electric power, and it is expected that it will be widely used in the future from the viewpoint of ensuring clean and safe electric power. Here, a propeller-type wind power generation facility suitable for large-scale power generation will be briefly described with reference to FIG. FIG. 15 is a schematic diagram showing a schematic configuration of a conventional wind power generation facility.

  As illustrated, the wind power generation facility W includes a tower 1 erected on the ground or the like, and a nacelle 2 installed at the upper end of the tower 1. A rotor head 4 having a wind turbine blade 3 is installed at one end of the nacelle 2. Further, inside the nacelle 2, a main shaft 6 connected to rotate integrally with the rotor head 4, a speed increaser 5 connected to the main shaft 6, and power generation driven by a shaft output of the speed increaser 5 The machine 7 is stored. In the wind power generation facility W, the rotor head 4 provided with the wind turbine blades 3 is rotated by receiving wind power, and the rotation is amplified by the amplifier 5 to drive the generator 7 to generate power.

  Further, the generator 7 is provided with a carbon brush for taking out the generated electric power. This carbon brush is always pressed against the slip ring (rotating drum) of the generator 7 and supplies electric power to the outside through a conductive wire connected to the carbon brush.

  Further, since the carbon brush of the generator 7 is constantly pressed against the slip ring (rotary drum) and wears out, it is necessary to replace it before it becomes unusable due to wear. Therefore, in the wind power generation facility W, an operator climbs to the nacelle 2 at the top of the tower 1 to inspect the carbon brush every predetermined period, determines the wear state of the carbon brush, and replaces the carbon brush when necessary. Etc. are being maintained. Further, in the wind power generation facility W, the generator 7 is normal due to the abnormal wear of the slip ring and the carbon brush due to the slippage of the carbon brush and the slip ring being deteriorated due to dust or the like inside the generator 7. May not work properly. For this reason, in the above inspection work, the worker also performs inspection of the contact surface between the carbon brush and the slip ring, cleaning of dust, and the like. In addition, the structure of the propeller type wind power generation equipment of a prior art as shown in figure is disclosed by patent document 1, for example.

  Patent Document 2 proposes a configuration of a brush wear notification device that detects the replacement time of a carbon brush. This brush wear notification device is configured to attach a terminal fitting so as to face the brush holder of the motor, and to operate the alarm when a brush pressing spring comes into contact with the terminal fitting.

  By the way, in wind power generation equipment, inspection work for preventing failure of the generator installed in the nacelle is regularly performed. In this inspection work, the worker must climb up to the top of the tower with a height of “50 to 60 m” and perform the work at a high place, and the labor burden on the worker is very large and the work cost is high. ing. Moreover, since it is necessary to stop the windmill and perform the above-described inspection work, it is a cause of a decrease in power generation efficiency. Therefore, in a wind power generation facility, it is desired to be able to reduce the labor burden and work cost of an operator and prevent a generator failure without causing a decrease in power generation efficiency.

  However, at present, in wind power generation facilities, technologies (systems and systems) that can reduce the labor burden and cost of workers and prevent power generator failures without causing a decrease in power generation efficiency. Method) is not known. Note that the brush wear notification device described in Patent Document 2 can notify the use limit (replacement time) of the carbon brush, but cannot predict the replacement time of the carbon brush in advance. Therefore, an efficient maintenance plan cannot be made even if the brush wear notification device is used. Further, the brush wear notification device described in Patent Document 2 cannot grasp any abnormality other than the length of the carbon brush and the state of the slip ring. Therefore, even if a brush wear notification device is used for a wind power generation facility, in order to grasp the state of the generator, an operator must perform an inspection operation to climb to the top of the tower every predetermined period. It is not possible to reduce the labor burden or improve the power generation efficiency.

  The present invention has been made in view of the above-mentioned problems, and its purpose is to reduce the labor load and work cost of workers who manage wind power generation facilities, and without causing a decrease in power generation efficiency. It is an object of the present invention to provide a failure prevention system for wind power generation facilities that prevents the occurrence of wind.

  The present invention made in order to solve the above problems is a failure of a wind power generation facility including a nacelle containing a generator that generates electric power by rotation of a rotor head having wind turbine blades, and a tower that supports the nacelle. The generator is provided with a slip ring and a carbon brush that is in contact with the slip ring, the camera installed in the nacelle, and a control unit that controls driving of the camera And a display unit that displays an image captured by the camera, and the surface of the carbon brush is provided with a mark for visually confirming the wear state of the carbon brush, and the control unit and the display unit are The camera is installed outside the wind power generation facility or in a region on the lower end side of the tower, and the camera is controlled by the control unit to provide the carbon block provided with the mark. Imaging the sheet and the slip ring, and wherein the displaying the captured image to the display unit.

Thus, according to the present invention, it is possible to display an image of “carbon brush and slip ring provided with a mark” captured by the camera on the display unit installed outside the wind power generation facility or on the lower end side of the tower. it can. Therefore, according to the present invention, the state of the carbon brush and the slip ring can be grasped in real time without the operator climbing to the nacelle at the top of the tower.
Further, in the present invention, since the surface of the carbon brush is provided with a mark that allows the wear state of the carbon brush to be visually recognized, an operator on the lower side of the tower can view the carbon brush by viewing the image on the display unit. The wear state of the carbon brush can be accurately grasped (for example, the replacement time of the carbon brush can be predicted based on the wear state of the carbon brush). As a result, according to the present invention, an efficient maintenance plan can be created, and failure of the wind power generation facility can be prevented in advance. Further, according to the present invention, it is sufficient to climb the tower only when work such as replacement of parts is necessary, and the labor of the worker is greatly reduced. Moreover, since the frequency | count that an operator climbs to the top of a tower reduces, the frequency | count which stops a windmill also decreases in connection with it. As a result, according to the present invention, power generation efficiency can be improved.

  Also, slip ring and carbon brush abnormalities are often accompanied by an increase in the temperature of the carbon brush as a precursor. Therefore, a thermocouple thermometer to which one end of a thermocouple is connected is provided in the vicinity of the display unit, the other end of the thermocouple is connected to a carbon brush of the generator, and the thermocouple thermometer It is desirable to provide the temperature of the carbon brush.

  With the above configuration, the worker can grasp the temperature of the carbon brush in real time without climbing the tower. Moreover, the abnormality of a slip ring or generator itself can be estimated from the temperature of a carbon brush. Therefore, according to the present invention, it is possible to prevent a slip ring and a generator from being damaged due to abnormal heat generation.

  Further, the present invention is a failure prevention system for wind power generation equipment comprising a nacelle that stores a generator that generates electric power by rotation of a rotor head equipped with wind turbine blades, and a tower that supports the nacelle, The generator is provided with a slip ring and a carbon brush that is in contact with the slip ring, a camera installed in the nacelle, a control unit that controls driving of the camera, and an image captured by the camera. A display unit for displaying an image, and a temperature indicating material that changes color when the temperature exceeds a predetermined temperature is affixed to the surface of the carbon brush, and the control unit and the display unit are provided on the wind power generation facility. The camera is installed outside or in a region on the lower end side of the tower, and the camera is controlled by the control unit, and the carbon brush to which the temperature indicating material is attached and the slip belt. By imaging the grayed, characterized in that to display the captured image to the display unit.

As described above, according to the present invention, the image of the “carbon brush with the temperature indicating material and the slip ring” captured by the camera is displayed on the display unit installed outside the wind power generation facility or on the lower end side of the tower. Can be made. Therefore, according to the present invention, the state of the carbon brush and the slip ring (the wear state and temperature of the carbon brush) can be grasped in real time without the operator climbing to the nacelle at the top of the tower.
Therefore, according to the present invention, the number of times the worker climbs to the top of the tower can be reduced, and as a result, the labor of the worker is greatly reduced. In addition, since the temperature of the carbon brush can be grasped in real time, it is possible to prevent the slip ring and the generator itself from being damaged due to abnormal heat generation.

  The slip ring and the carbon brush are housed in a box-shaped or cylindrical generator main body, and the guide rail formed inside the main body and the guide according to a signal from the controller. A slider that slidably moves on a rail; and a storage case provided at an end of the guide rail. The camera is mounted on the slider, and the camera is movable along the guide rail. The control unit moves the slider along the guide rail, arranges the camera at a position where the slip ring and the carbon brush can be imaged, and images the slip ring and the carbon brush to the camera. After that, it is desirable that the camera is stored in the storage case by moving the slider along the guide rail.

  The reason why the camera can be moved as described above is to enable imaging of a plurality of carbon brushes installed in the generator of the wind power generation facility. That is, according to the present invention, since the camera can be moved to a desired position, the states of a plurality of carbon brushes can be confirmed. Further, according to the present invention, when the slip ring and the carbon brush are not imaged, the camera is stored in the storage case, so that the camera can be protected from dust in the generator.

  The slip ring and the carbon brush are housed in a box-shaped or cylindrical generator main body, a guide rail formed on the main body, and a slider that slidably moves on the guide rail. A substantially dome-shaped protective cover that is rotatably supported on one surface of the slider, and an arm portion that is erected from the one surface of the slider and is opposed to the outer peripheral side surface portion of the protective cover A wiping material that is held by the arm portion and contacts the outer peripheral side surface portion of the protective cover, and a movement that rotates the protective cover while moving the slider along the guide rail in accordance with a signal from the control portion A rotation mechanism, and the control unit moves the slider along the guide rail so that the slip ring and the carbon brush can image the camera. The slip ring and the carbon brush are imaged by the camera, and the outer peripheral side surface of the protective cover is rotated by the rotation of the protective cover accompanying the movement of the slider. It is desirable that the dirt adhered to the wiping material and removed from the protective cover is removed.

  With the above configuration, each time the slider is moved on the guide rail, the protective cover can be brought into contact with the wiping material while being rotated, so that the dirt on the protective cover can be effectively removed. Moreover, since the protective cover contacts the wiping material while rotating, the entire outer peripheral side surface of the protective cover can be cleaned.

  In addition, a wiping material is installed inside the storage case so as to contact the stored camera, and the camera moves on the guide rail and is stored in the storage case. It is desirable that dirt adhered by the wiping material is removed.

  With the above configuration, it is possible to prevent deterioration of a captured image (for example, deterioration of a captured image due to dust adhering to a camera lens) caused by the influence of dust attached to the camera.

  In addition, an LED lamp is installed on the slider, and the LED lamp has an operation switch that is turned on / off by an operator and is turned on / off by a signal from the control unit. The control unit is configured to turn on the LED lamp and irradiate the carbon brush and the slip ring with lamp light when the camera images the carbon brush and the slip ring. Is desirable.

  With the above configuration, the inside of the generator can be clearly imaged, and as a result, the state of the carbon brush and the slip ring can be accurately grasped. Further, by providing the operation switch, an operator who has climbed the nacelle can use an LED lamp as lighting equipment when working. That is, since an operator can use an LED lamp as work illumination, it is not necessary to carry a large illumination facility (flashlight) and climb to the nacelle (the labor of the operator is reduced).

  The nacelle is provided with a dust collecting device for sucking dust inside the generator, and the carbon brush has a side surface portion held by a hollow cylindrical brush holder and a tip portion of the carbon brush. It is urged from the rear end portion toward the front end portion so as to contact the slip ring, and a concave vertical groove penetrating from the front end portion to the rear end portion is formed on the side surface portion. The dust generated from the contact portion between the brush body and the slip ring is preferably sucked into the dust collector through the vertical groove.

With the above configuration, dust inside the generator can be removed, so that the imaging environment of the camera can be greatly improved. Thereby, the state of a carbon brush and a slip ring can be grasped correctly.
Further, by forming the vertical groove in the carbon brush, dust generated in a large amount inside the generator can be efficiently removed by the dust collector. As a result, according to the present invention, it is possible to prevent a failure of the generator that occurs when the carbon brush is stuck to the brush holder by dust.

  According to the present invention, there is provided a failure prevention system for a wind power generation facility that can reduce the labor burden and work cost of an operator who manages the wind power generation facility and prevents the failure of the generator without causing a decrease in power generation efficiency. be able to.

It is designed to prevent the wind power generation facility W from being broken, so that an operator who manages the wind power generation facility W can grasp the state of the generator 7 without climbing to the nacelle 2 at the top of the tower 1. is there. The generator 7 includes a box-shaped generator main body 10 (hereinafter referred to as “main body 10”), and components such as a slip ring 8 and a carbon brush 9 are provided inside the main body 10. It is stored. The carbon brush 9 is held by the brush holder 11 and is urged toward the slip ring 8 so that the lower end portion of the carbon brush 9 is in contact with the slip ring 8. Further, the brush holder 11 is formed with a notch 11a (see FIG. 6) so that one side of the carbon brush 9 can be visually recognized. In addition, since the structure of the wind power generation equipment W is the same as that of FIG.

  As shown in FIGS. 1 and 2, the wind power generation facility failure prevention system of the present embodiment includes a CCD camera (hereinafter simply referred to as “camera”) 20 and an LED lamp 30 installed in the nacelle 2, 2 and a dust collector 50 for sucking dust from the generator 7 and a control system S installed in a region R at the lower end (the ground side) of the tower 1. Further, the camera 20 and the LED lamp 30 are installed on a slider 40 that is movable along the guide rail 12 provided inside the main body 10 of the generator 7 (on the slip ring 8 side). A power supply unit 110 that supplies power to the camera 20, the LED lamp 30, the slider 40, the dust collector 50, and the control system S is provided in the region R at the lower end of the tower 1. The power supply unit 110 supplies power to each device (camera 20, LED lamp 30, slider 40, dust collector 50) and control system S via a power line.

  The camera 20 is configured by a general small color CCD camera. Moreover, the dust collector 50 is comprised by the general electric vacuum cleaner. Reference numeral 50a denotes a dust collector main body, and 50b denotes a hose for sucking dust. Moreover, in this embodiment, although the power supply part 110 and the control system S are provided in the lower end part of the tower 1, this is only an example to the last. For example, the power supply unit 110 and the control system S may be installed in a management building or the like outside the wind power generation facility W.

  The control system S also includes a control device (control unit) 100, a display (display unit) 101 for displaying an image captured by the camera 20, and various requests from the user (camera imaging request, dust collector operation request). Etc.) and an input device 102 composed of a keyboard and a mouse.

  The control device 100 is electrically connected to each device (the camera 20, the LED lamp 30, the slider device 40, and the dust collecting device 50), and transmits a control signal to each device in response to a request from the user. It controls the operation of the device. The connection between the control system 100 and each device (camera 20, LED lamp 30, slider 40, and dust collecting device 50) may be wired or wireless. The specific configuration of the control device 100 is not particularly limited. For example, the control device 100 is configured by a computer including a CPU, a memory, an input / output interface, a communication interface, and the like. In this case, a program for controlling the operation of each device (camera 20, LED lamp 30, slider device 40, and dust collecting device 50) is stored in the memory. The functions of the control device 100 (functions for controlling each device) are realized by the CPU executing a program stored in the memory. The display 101 is realized by, for example, a color liquid crystal display device having a known configuration.

  In the present embodiment, as shown in FIG. 3A, the wear confirmation mark 13 that allows the wear state of the carbon brush 9 to be visually recognized on the surface (at least one surface) of the carbon brush 9 formed in a substantially rectangular parallelepiped shape. Is printed. The wear confirmation mark 13 includes, for example, a red upper mark 13a, a yellow middle mark 13b, a blue (green) lower mark 13c, and the like. Each of the marks 13a, 13b, 13c is formed in the same rectangular shape. From the upper end side of the carbon brush (on the side opposite to the contact surface with the slip ring 8), the upper mark 13a, the interrupt mark 13b, the lower mark The marks 13c are printed adjacent to each other in the order. Thus, in this embodiment, by providing the wear confirmation mark 13 on the carbon brush 9, the user (operator) can easily grasp the wear state of the carbon brush 9. In addition, the code | symbol 15 in a figure has shown the electric wire for sending electric power from the carbon brush 9 to the exterior.

  Further, in the present embodiment, a temperature indicating material 14 (a temperature indicating material that changes to a predetermined color) 14 that changes in color when the temperature reaches a predetermined temperature or higher may be attached to the surface (at least one surface) of the carbon brush 9. Since the color of the temperature indicating material 14 changes when the temperature of the temperature indicating material 14 exceeds a predetermined temperature, the temperature indicating material 14 becomes a standard for knowing the temperature state of the carbon brush 9. In the illustrated example, the temperature indicating material 14 having a size smaller than the wear confirmation mark 13 is attached on the wear confirmation mark 13, but the present invention is not particularly limited thereto. The temperature indicating material 14 is a position where the camera 20 can capture an image, and may be attached to any position as long as it is above the carbon brush 9 (on the electric wire 15 side). For example, as shown in FIG. 3 (b), the temperature indicating material 14 may be pasted on the brush takeout fitting 16 of the carbon brush 9.

  Next, the installation position of the camera 20 and the dust collector 50 of this embodiment and the structure which moves the camera 20 are demonstrated using FIGS. 4-7. In FIG. 7, the temperature indicating material 14 affixed to the carbon brush 9 is omitted for convenience (because the figure becomes complicated).

  As shown in FIG. 4, the generator 7 installed in the nacelle 2 includes a box-shaped main body 10 mainly having a hollow rectangular tube shape, and the main body 10 includes each component (slip ring). 8, carbon brush 9, component parts such as brush holder 11). The main body 10 is provided with a lid 10a that is detachable from the main body 10. By removing the lid 10a, maintenance work such as replacement and inspection of the carbon brush 9 can be performed as shown in FIG. It has become. In the illustrated example, a lid body 10a (two lid bodies 10a) is provided on a side surface near the installation position of the carbon brush 9 among the side surfaces of the box-shaped main body 10. In the present embodiment, the camera 20 is attached to the back surface (inside the apparatus) of the lid 10a, and the camera 20 can image the slip ring 8 and the carbon brush 9 inside the generator 7 in operation. Yes. Hereinafter, the installation structure of the camera 20 will be described in detail.

  Specifically, as shown in FIGS. 4 and 5, a guide rail 12 is provided on the back side of the lid 10a, and a slider 40 that is slidably moved on the guide rail 12 is provided. A camera 20 is installed on the slider 40. An LED lamp 30 is installed on the slider 40. The guide rail 12 is arranged in parallel with the main shaft 6 (see FIG. 1) inside the nacelle 2.

  As described above, the installation of the device such as the camera 20 on the lid 10 that is detachable from the main body 10 has the following advantages. Specifically, maintenance work such as replacement of the carbon brush 9 is performed by removing the lid 10 a from the main body 10. Since the device such as the camera 20 is also removed together with the removed lid 10a (see FIG. 6), the maintenance work can be performed without worrying about the device such as the camera 20.

  The slider 40 is controlled and driven by the control device 100 (see FIGS. 1 and 2), and moves on the guide rail 12 in response to a request (control signal) from the control device 100. It is possible to stop at an arbitrary position requested from the control device 100. In addition, since the structure of the guide rail 12 and the slider 40 of this embodiment is realizable with the structure of a known electric actuator etc., detailed description is abbreviate | omitted.

  The camera 20 is covered with a hollow dome-shaped protective cover 21 formed of a transparent material (for example, transparent resin), and moves along the guide rail 12 while being covered with the protective cover 21. (It can be moved to any position on the guide rail 12). Further, the lens of the camera 20 is disposed so as to face the “printing surface of the wear check mark 13 of the slip ring 8 and the carbon brush 9” (see FIGS. 4 and 7). With this configuration, the camera 20 can image the wear confirmation mark 13 of each carbon brush 9 by moving on the guide rail. Similarly to the lens of the camera 20, the LED lamp 30 is disposed so as to face the “print surface of the wear confirmation mark 13 of the slip ring 8 and the carbon brush 9”. The lamp 9 is irradiated with the wear confirmation mark 13 ”of the brush 9.

  A camera storage case 23 is provided on one end side of the guide rail 12 so as to cover the outer periphery of the guide rail 12 (see FIG. 5). The camera storage case 23 is erected on one end side of the guide rail 12 on the back side of the lid 10a, and is formed in a shape that can be stored covering the outer periphery of the protective cover 21 that has moved on the guide rail 12. (In the example shown in the figure, the plate-shaped member is formed in a C shape in plan view). In addition, a wiping material 25 that contacts the outer surface of the protective cover 21 that houses the camera 20 is installed inside the camera storage case 23. With this configuration, when the protective cover 21 moving on the guide rail 12 is stored in the camera storage case 23, dirt attached to the surface is removed by the wiping material 25. In addition, the wiping material 25 is comprised with a bristle brush, cloth (cloth, such as a felt and a nonwoven fabric), etc., for example.

  In the present embodiment, the camera 20 is housed in the protective cover 21, but the present invention is not limited to this. The protective cover 21 may be omitted. In this case, the wiping material 25 inside the camera storage case 23 is brought into direct contact with the camera 20 moving on the guide rail 12. With this configuration, when the camera 20 moving on the guide rail 12 is stored in the camera storage case 23, dirt attached to the surface is removed by the wiping material 25.

  The lid 10a is formed with a plurality of dust collecting holes 10a1 into which the dust collecting hoses 50b of the dust collecting device 50 are inserted (see FIG. 5), and each dust collecting hole 10a1 has a dust collecting hole. The tip of the hose 50b is inserted (see FIG. 4). With this configuration, by driving the dust collector 50, dust can be sucked from the inside of the generator 7 (inside the main body 10). And since the dust inside the generator 7 is removed, the imaging environment of the camera 20 can be improved significantly. In addition, failure of the generator 7 caused by dust is prevented. In the present embodiment, the dust collector 50 is constituted by one dust collector main body 50a and a plurality of hoses 50b, but this is merely an example.

  Next, operation | movement of the failure prevention system of the wind power generation facility of this embodiment is demonstrated.

  First, the worker activates the control system S in the lower end region R of the tower 1 of the wind power generation facility W to be inspected. Next, the operator operates the input device 102 to input a “camera imaging command” to the control device 100. When receiving the “camera imaging command”, the control device 100 transmits a lighting signal to the LED lamp 30 to light the LED lamp 30 and transmits a driving signal to the camera 20 to drive the camera 20. Thereby, imaging by the camera 20 is started, and an image captured by the camera 20 is input to the display 101 via the control device 100 (or directly input from the camera 20 to the display 101) and displayed on the display 101. The

  Next, the operator operates the input device 102 while looking at the display 101 and moves the camera 20 to check the state of the generator 7. Specifically, in response to a request from the operator, the control device 100 drives the slider 40 to move the camera 20 along the guide rail 12. As a result, the camera 20 images “the slip ring 8 and the carbon brush 9 (the carbon brush 9 including the wear confirmation mark 13 and the temperature indicating material 14), and the captured image is displayed on the display 101. The wear state of the carbon brush 9 can be confirmed from the wear confirmation mark 13 in the image displayed on the display 101. Further, the operator can change the generator 7 from the temperature indicating material 14 in the image displayed on the display 101. Then, the operator can confirm the state of the plurality of carbon brushes 9 in order by moving the camera 20 while looking at the display 101. To go.

  Specifically, in the image displayed on the display 101, the worker uses the wear confirmation mark 13 of the carbon brush 9 and the reference line 11 b formed on the brush holder 11 that holds the carbon brush 9 (FIGS. 6 and 7). And the wear state of the carbon brush 9 is confirmed. As shown in FIG. 7, when the wear confirmation mark 13 is located above the reference line 11b, the operator recognizes that it is not time to replace the carbon brush 9. Further, when the lower mark 13c of the wear confirmation mark 13 is positioned on the reference line 11b, the operator recognizes that the wear is progressing although it is not the replacement time of the carbon brush 9, and predicts the replacement time. Create a maintenance plan. Further, when the interruption mark 13b in the wear confirmation mark 13 is positioned on the reference line 11b, the operator recognizes that the replacement time of the carbon brush 9 is near and creates a replacement plan for the carbon brush 9. When the upper mark 13a in the wear confirmation mark 13 is positioned on the reference line 11b, the operator determines that the carbon brush 9 needs to be replaced, makes an immediate replacement plan for the carbon brush 9, and Prioritize facility maintenance.

  In addition, in the image displayed on the display 101, if the temperature indicating material 14 attached to the carbon brush 9 is not changed to a predetermined color, the worker has assumed that the generator 7 has no temperature abnormality. judge. In addition, in the image displayed on the display 101, the operator determines that a temperature abnormality has occurred in the generator 7 if the temperature indicating material 14 attached to the carbon brush 9 has changed to a predetermined color. And create a corresponding maintenance plan. By making a maintenance plan in this way, it is possible to prevent a failure of the slip ring 8 or the generator 7 itself due to abnormal heat generation.

  Moreover, since the operator can also confirm the state of the slip ring 8 displayed with the carbon brush 9 in the image displayed on the display 101 (because the state of the slip ring 8 can be visually confirmed), for example, Thus, it is possible to take measures against the abnormality of the slip ring 8.

  In addition, the operator can check the dirt state of the carbon brush 9 and the slip ring 8 in the image displayed on the display 101 (confirm the dirt condition inside the generator 7 from the lower side of the tower 1. be able to). Then, the operator can remove dust from the carbon brush 9 and the slip ring 8 by operating the control device 100 and driving the dust collecting device 50 as necessary. Specifically, the control device 100 receives a request from an operator and drives the dust collecting device 50. Thereby, the dust inside the generator 7 is attracted | sucked by the dust collector.

  Thus, in the present embodiment, in the region R on the lower end side of the tower 1, the inside of the generator 7 can be cleaned while looking at the display 101, and the imaging environment of the camera 20 can be changed without climbing on the tower 1. It can be greatly improved. As a result, a clear image inside the generator 7 can be displayed on the display 101, and the current state of the generator 7 can be accurately grasped. Moreover, the malfunction of the generator 7 resulting from dust can be prevented.

  Further, when the inspection work is finished, the worker inputs a work end command to the control device 100 via the input device 102. When the control device 100 receives the work end command, the control device 100 turns off the LED lamp 30 and stops driving the camera 20. In addition, the control device 100 transmits a control signal (movement command) that instructs the slider 40 to move to the home position (the position of the camera storage case 25). When the slider 40 receives the movement command, the slider 40 moves to the home position along the guide rail 12 and stops. By this movement, when the protective cover 21 on the slider 40 is stored in the camera storage case 23, the wiping material 25 removes dirt. Further, the camera 20 and the LED lamp 30 are protected from dust in the generator 7 because they are stored in the camera storage case 25 when imaging is not performed.

  As described above, according to the present embodiment, the state of the carbon brush 9 and the slip ring 8 can be grasped in real time without the operator climbing to the nacelle 2 at the top of the tower 1. Moreover, even if an operator does not climb to the nacelle 2 at the top of the tower 1, the inside of the generator 7 can be cleaned. As a result, according to the present embodiment, it is possible to reduce the labor burden and work cost of the operator who manages the wind power generation facility W. Moreover, according to this embodiment, since an efficient maintenance plan can be made, it becomes possible to perform maintenance without incurring a decrease in power generation efficiency.

  Next, a first modification of the present embodiment will be described with reference to FIG. FIG. 8 is a schematic diagram for explaining a first modification of the present embodiment. In the description of the present modification, the description will focus on parts different from the above-described embodiment, and the description of the same configuration will be omitted. In the description of this modification, the same reference numerals are assigned to the same configurations (and corresponding configurations) as those in the above-described embodiment.

  In this modification, instead of the “configuration for imaging the temperature indicating material 14 affixed to the carbon brush 9” in the above-described embodiment, a configuration for measuring the temperature of the carbon brush 9 using a thermocouple is used. In addition, this modification is the same as embodiment mentioned above except having changed the structure which monitors the temperature of the generator 7. FIG.

  Specifically, a thermocouple thermometer 60 to which one end of the thermocouple 61 is connected is provided in a region R (near the control system S) on the lower end side of the tower 1. The other end of the thermocouple 61 is connected to the carbon brush 9 of the generator 7 housed in the nacelle 2. With this configuration, the thermocouple thermometer 60 presents the temperature of the carbon brush 9 in the region R on the lower end side of the tower 1 (in the vicinity of the control system S). Therefore, also in this modification, the temperature of the generator 7 can be monitored without the operator climbing on the tower 1 as in the above-described embodiment.

  Next, a second modification of the present embodiment will be described with reference to FIGS. 9 and 10 are schematic views for explaining a carbon brush used in the generator of the second modification of the present embodiment. In the description of the present modification, the description will focus on parts different from the above-described embodiment, and the description of the same configuration will be omitted. In the description of this modification, the same reference numerals are assigned to the same configurations (and corresponding configurations) as those in the above-described embodiment. In FIGS. 9 and 10, the wear confirmation mark 13 and the temperature indicating material 14 are omitted for convenience of explanation.

  In the second modified example, the shape of the carbon brush 9 is changed in order to prevent the carbon brush 9 from being agitated by dust inside the generator 7 which is a cause of a decrease in power generation efficiency or a failure of the generator 7. The second modification is the same as the above-described embodiment except for the structure of the carbon brush 9.

  Here, the firmness of the carbon brush 9 will be described. In the generator interior 7, a large amount of dust enters between the carbon brush 9 and the hollow cylindrical brush holder 11 that holds the carbon brush 9. Even if this dust increases the frictional resistance between the carbo brush 9 and the brush holder 11, and the carbon brush 12 is urged toward the slip ring 8, the carbon brush 12 does not operate smoothly (the carbon brush 12). Cause a phenomenon that And this phenomenon (solid astringency of the carbon brush 9) decreases the power generation efficiency of the generator by lowering the energization between the carbon brush 9 and the slip ring 8, or damages the slip ring 8 due to heat generation. .

  Therefore, in the second modification, as shown in FIG. 9, a configuration in which vertical grooves 9 a are provided in the side surface portion of the carbon brush 9 is employed to prevent the carbon brush 9 from becoming astringent.

  Specifically, the carbon brush 9 includes a brush body 9A whose tip end abuts against the slip ring 8 and wears, and an electric wire 15 connected to the rear end portion of the brush body 9A. Further, the carbon brush 9 is inserted into the hollow cylindrical brush holder 11 so that the side surface thereof is held by the brush holder 11. The brush body 9A is urged from the rear end portion toward the tip portion (biased in the Y1 direction) by an urging means (biasing means such as a spring) (not shown), and the tip portion is brush holder 11. Projecting from the outer periphery of the slip ring 8.

  The brush body 9A is formed in a substantially rectangular parallelepiped shape, and a concave vertical groove 9a extending from the front end portion to the rear end portion (a concave vertical groove 9a penetrating from the front end portion to the rear end) is formed on the side surface portion. A plurality are formed. The vertical groove 9a is formed in a rectangular shape. Further, the vertical groove 9a is formed linearly along the longitudinal direction (Y1 direction) of the brush body 9A. In the illustrated example, the longitudinal grooves 9a are formed in two side surfaces of the four side surfaces of the brush body 9A. However, the present invention is not limited to this. For example, the vertical groove 9a may be formed in all four side portions. In addition, the number of vertical grooves 9a (a single groove may be sufficient) and the depth dimension are appropriately designed.

  With the above configuration, the contact area between the brush body 9 </ b> A of the carbon brush 9 and the brush holder 11 can be reduced. As a result, even if dust enters between the brush body 9A and the brush holder 11, the frictional resistance can be kept low, and the carbon brush 9 can be prevented from becoming astringent. Therefore, if the carbon brush 9 of this modification is used for the generator 7 of the wind power generation facility W, a decrease in power generation efficiency and a failure of the generator 7 due to the firmness of the carbon brush 9 are prevented.

  Moreover, the dust collection efficiency of the dust collector 50 can be improved by providing the brush body 9A with the vertical grooves 9a. That is, when the dust collecting device 50 is driven, air is sucked from the dust collecting hole 10a1 in the vicinity of the rear end portion of the carbon brush 9, and the air gap (vertical groove 9a) between the brush holder 11 and the brush body 9A. Convection of air from the slip ring 8 toward the dust collection hole 10a1 occurs in the gap formed by the above. That is, the gap formed by the vertical groove 9a functions as an air flow path. As a result, dust generated from the contact portion between the brush body 9 </ b> A and the slip ring 8 is sucked from the dust collection hole 10 a 1 along the gap between the brush holder 11 and the brush body 9, and outside the generator 7. It will be discharged efficiently.

  As described above, according to the second modification, the dust collector 50 can efficiently remove dust generated in a large amount inside the generator 7, so that there is a possibility that solid astringency of the carbon brush 9 due to dust occurs. Is reduced. That is, according to the second modified example, the risk of the carbon brush B becoming astringent can be reduced, so that a decrease in power generation efficiency and a failure of the generator 7 are prevented.

  Further, in the second modification, as shown in FIG. 10, the longitudinal groove 9b on the side surface portion of the brush body 9A may be formed in a concave shape in an arc shape. Specifically, a plurality of vertical grooves 9b that are recessed in an arc shape penetrating from the front end portion to the rear end portion may be formed in the side surface portion of the brush body 9A. The vertical groove 9b is formed in a straight line along the longitudinal direction (Y1 direction) of the brush body 9A, similarly to the vertical groove 9a. In this way, by forming the vertical groove 9b into a shape recessed in an arc shape, the flow of air passing through the gap formed by the vertical groove 9b can be made smooth, and dust can be discharged more efficiently. It can be performed.

  The shape of the vertical grooves 9a and 9b shown in the second modification is merely an example. For example, the longitudinal groove 9 may be formed in a shape recessed in an inverted triangular shape.

  Next, a third modification of the present embodiment will be described with reference to FIG. FIG. 11 is a schematic diagram for explaining the structure of the guide rail provided in the generator of the third modified example of the present embodiment. In the description of the present modification, the description will focus on parts different from the above-described embodiment, and the description of the same configuration will be omitted. In the description of this modification, the same reference numerals are assigned to the same configurations (and corresponding configurations) as those in the above-described embodiment.

  As shown in the figure, in the third modified example, the guide rail 12 is not provided on the lid 10a provided on the main body 10 of the generator 7, but the guide rail is provided on the inner side of the main body 10 near the lid 10a. 12 is attached.

  Specifically, in the third modification, one end of the guide rail 12 is rotatably supported at a position in the vicinity of the lid 10a on the back surface side (inside) of the main body 10. The guide rail 12 has a free end at the other end, and is configured to be rotatable around a support point at the one end. The guide rail 12 is disposed at a position indicated by a solid line in the normal state of driving the system. Further, when the operator removes the lid 10a from the main body 10 for maintenance, the guide rail 12 is rotated and retracted to the position of the broken line shown in the drawing. Similar to the above-described embodiment, a slider 40 on which the camera 20 is mounted is installed on the guide rail 12.

  With this configuration, when the carbon brush 9 is replaced or the generator 7 is maintained, the guide rail 12 can be moved to a position that does not hinder the work, and the work can be facilitated. .

  Next, a fourth modification of the present embodiment will be described with reference to FIGS. 12 and 13 are schematic diagrams for explaining a camera moving mechanism according to a fourth modified example of the present embodiment. FIG. 12 is a schematic diagram viewed from the top, and FIG. 13 is a schematic diagram viewed from the side. Show. In the description of the present modification, the description will focus on parts different from the above-described embodiment, and the description of the same configuration will be omitted. In the description of this modification, the same reference numerals are assigned to the same configurations (and corresponding configurations) as those in the above-described embodiment.

  In the fourth modified example, a guide rail 12 is formed outside the main body portion 10, and a slider 40 that is slidably moved on the guide rail 12 is provided (see FIG. 13). The slider 40 includes a rail guide 43, and the rail guide 43 is slidably mounted on the guide rail 12.

  Further, the camera 20 and the protective cover 21 are attached to one surface (the lower surface shown in FIG. 13) of the slider 40, and the motor M is attached to the other surface (the upper surface shown in FIG. 13) of the slider 40. In the motor M, the rotation shaft passes through the slider 40, and one end of the rotation shaft protrudes from the lower surface side of the slider 40. Then, a pinion gear 62 is fitted on a rotating shaft protruding from the lower surface side of the slider 40, and the pinion gear 62 is rotated by driving the motor M. The motor M is driven by a signal from the control device 100.

  The camera 20 is installed on one surface (the lower surface shown in FIG. 13) of the slider 40 via a support member 42. The protective cover 21 is disposed so as to cover the camera 20, and a base end portion of the protective cover 21 is rotatably supported on one surface of the slider 40. Further, a gear 21 a that meshes with a pinion gear 62 attached to the rotating shaft of the motor M is formed on the outer peripheral side surface portion of the protective cover 21.

  Further, an arm portion 41 is provided upright on one surface (the lower surface shown in FIG. 13) of the slider 40 so as to be opposed to the outer peripheral side surface portion of the protective cover 21. A wiping material 25 that contacts the protective cover 21 is attached to the arm portion 41. In addition, the wiping material 25 is comprised with a bristle brush, cloth (cloth, such as a felt and a nonwoven fabric), etc., for example.

  A rack gear 60 that meshes with the pinion gear 62 is installed outside the main body 10 (position adjacent to the guide rail 12). The rack gear 60 is gear-cut (toothed) on a side surface of a flat bar, and is installed along the longitudinal direction of the guide rail 12. The rack gear 60 is attached to the main body 10 by a support member (not shown) or the like so as to be disposed below the slider 40 (downward as shown in FIG. 13).

  In the fourth modified example, an opening 10 b is formed in the main body 10 (at a position adjacent to the guide rail 12) along the longitudinal direction of the guide rail 12. The “arm portion 41 holding the camera 20, the protective cover 21, and the wiping material 25” installed on one surface (the lower surface shown in FIG. 13) of the slider 40 is inserted into the opening 10 b and Arranged inside.

  When the motor M is driven, the pinion gear 62 meshed with the rack gear 60 rotates, and thereby the slider 40 moves on the guide rail. With this configuration, the “camera 20, the protective cover 21, and the arm portion 41 that holds the wiping material 25” installed on the slider 40 move together with the slider 40. Can be arranged.

Further, since the pinion gear 62 meshes with the gear 21 a of the protective cover 21, when the pinion gear 62 is rotated, the protective cover 21 rotates on one surface of the slider 40. That is, when the motor M is driven to rotate the pinion gear 62, the slider 40 moves along the guide rail 12, and the protective cover 21 rotates on one surface of the slider 40 (note that the camera 20 is a slider). 40 so that it does not rotate on top of 40).
The “motor M, rack gear 60, pinion gear 62, and gear 21a of the protective cover 21” constitute a moving and rotating mechanism that rotates the protective cover 21 while moving the slider 40 along the guide rail 12.

  Then, by driving the motor M and moving the slider 40, the outer peripheral side surface of the protective cover 21 comes into contact with the wiping material 25 while rotating, so that the dirt attached to the protective cover 21 is removed. The

  As described above, according to the fourth modification, each time the slider 40 is moved on the guide rail 12, the protective cover 21 can be brought into contact with the wiping material 25 while being rotated. It can be effectively removed. Moreover, in the 4th modification, since the protective cover 21 rotates and contacts the wiping material 25, the whole outer peripheral side surface part of the protective cover 21 can be cleaned.

  Next, a fifth modification of the present embodiment will be described with reference to FIG. FIG. 14 is a schematic diagram for explaining a camera moving mechanism according to a fifth modification of the present embodiment. In the description of the present modification, the description will focus on parts different from the above-described embodiment, and the description of the same configuration will be omitted. In the description of this modification, the same reference numerals are assigned to the same configurations (and corresponding configurations) as those in the above-described embodiment.

  In the fifth modification, after adopting a configuration in which the guide rail 12 is provided inside the main body portion 10, the protective cover 21 supported by the slider moving on the guide rail is rotated and brought into contact with the wiping material 25. Thus, the dirt on the protective cover 21 is effectively removed.

  In the fifth modified example, the protective cover 21 is rotatably supported on the upper surface of the slider 40. For example, a support groove (not shown) that is recessed in a ring shape in which a base end portion (a base end portion in a ring shape in cross section) of the protective cover 21 can be rotatably inserted is provided on the upper surface of the slider 40. The protective cover 21 is configured to be rotatably supported by the slider 40 by inserting the base end portion of the 21 into the support groove.

  In addition, an arm portion 41 is provided so as to stand from one end portion of the upper surface of the slider 40 (the end portion on the side where the lens of the camera 20 is not disposed) and to face the outer peripheral side surface portion of the protective cover 21. A wiping material 25 that contacts the protective cover 21 is attached to the arm portion 41.

  In the fifth modification, a rack gear 60 is installed along the longitudinal direction of the guide rail 12 at a position adjacent to the guide rail 12 inside the main body 10 of the generator 7. The rack gear 60 is attached to the main body 10 by a support member (not shown) or the like so as to be disposed above the slider 40. A gear 21 a that meshes with the rack gear 60 is formed on the outer peripheral portion of the protective cover 21 on the base end side. In the fifth modification, the “driving means such as a motor for driving a slider (not shown), the rack gear 60, and the gear 21a of the protective cover 21” rotate the protective cover 21 while moving the slider 40 along the guide rail 12. It is a moving and rotating mechanism.

  With this configuration, when the slider 40 moves on the guide rail 12, the protective cover 21 rotates on the upper surface of the slider 40 by the rack portion 60 and the gear 21a. And since the outer peripheral side surface part rotates, the protective cover 21 contacts the wiping material 25, Therefore The dirt adhering to the surface part of the protective cover 21 is removed. Thus, according to the fifth modified example, as in the fourth modified example, it is possible to effectively remove the dirt on the protective cover 21. Further, in the fifth modified example, since the protective cover 21 rotates and contacts the wiping material 25, the entire outer peripheral side surface portion of the protective cover 21 can be cleaned.

  In addition, this invention is not limited to embodiment mentioned above and a modification (1st modification-5th modification), A various change is possible within the range of the summary.
