DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of the present application.

[0030] The tower of the wind turbine serves as the support base of the generator set, and also needs to absorb the vibration of the set, so its performance maintenance is crucial. In order to ensure the health of the tower, the tower needs to be regularly inspected and cleaned to prevent rust. Through analysis of the prior art, it can be found that the current existing equipment can only complete the cleaning of the tower by wiping, and cannot realize the paint spraying maintenance of the tower. After cleaning, manual further maintenance is still needed, and the labor cost has not been significantly reduced.

[0031] Therefore, the present application provides a new energy wind power generation equipment maintenance device, as shown in Figure 1 The device comprises a cylindrical base and a cleaning device 3.

[0032] The cylindrical base serves as the base of the maintenance device, and is used to carry the cleaning device 3. The cylindrical wall of the cylindrical base has a certain thickness, which is generally 10-20 cm. The specific thickness value is based on the applicable wind turbine tower, for example, when it is applicable to smaller wind turbine towers, the thickness can be configured as 10 cm, and when it is applicable to larger wind turbine towers, the thickness can be configured as 20 cm. It should be noted that the cylindrical base is made of steel material, which can be composed of main ribs and an external skin.

[0033] In order to realize the function of the maintenance device in the present embodiment, the main rib structure on the circumferential upper surface of the cylindrical base is provided with a ring groove with a cross-section in the shape of a cross; the cleaning device 3 is in sliding connection with the cylindrical base through the driving wheel 3008 embedded in the ring groove; that is, the driving wheel 3008 can roll in the ring groove, and since the ring groove is in the shape of a cross-section, the driving wheel 3008 will not come out of the ring groove, so that the cylindrical base of the maintenance device and the cleaning device 3 are a relatively stable whole. Here, stability does not mean that the connection relationship between the two is fixed, but means that although the two are in sliding connection, the positional relationship between the two is relatively stable, that is, the cleaning device 3 will not be separated from the cylindrical base.

[0034] In order to facilitate the transportation of the maintenance device, in the present embodiment, the cylindrical base can be composed of a whole structure (i.e. the main ribs form a whole circular cylinder); or can be composed of a first component 1 and a second component 4, as shown in Figures 4-6The first assembly 1 and the second assembly 4 are both arc-shaped plate structures; the contact surfaces of the first assembly 1 and the second assembly 4 are provided with embedded blocks, the second assembly 4 is provided with embedded grooves matched with the embedded blocks, and further provided with fixing holes penetrating through the embedded blocks and the embedded grooves, and the first assembly 1 and the second assembly 4 are connected stably by inserting a bolt into the fixing holes. The first assembly 1 and the second assembly 4 are combined to form a cylindrical base; the structure is convenient to disassemble, and when the first assembly 1 and the second assembly 4 are separated, the annular groove is also divided into two parts, so that the cleaning device 3 can be smoothly taken out; and the convenience degree of disassembly is further increased.

[0035] Since the stain area needs to be accurately positioned, the cylindrical base relative to the ground where the tower is located should have a certain stability; based on this, in the embodiment, the first assembly 1 is taken as the main body, and a plurality of insertion rods 2 are uniformly and spacedly arranged on the side of the first assembly 1 opposite to the side where the annular groove is located; meanwhile, a insertion hole is also matched arranged on the ground where the tower is located, and the cylindrical base is more stable during working by inserting the insertion rod 2 into the insertion hole. Meanwhile, in order to realize the modular design, the insertion rod 2 can be fixed with the first assembly 1 in a threaded connection manner, so that the insertion rod 2 can be conveniently disassembled.

[0036] In addition, it should be noted that the inner diameter of the cylindrical base is not limited, and the inner diameter size can be flexibly set based on the need to adapt to the fan.

[0037] In order to realize the purpose of the present application, that is, the maintenance device can meet the cleaning of the tower and the paint spraying maintenance of the tower; next, the cleaning device 3 will be described in detail. As shown in Figure 2 The cleaning device 3 includes a bearing frame 307, and a circumferential driving mechanism, a longitudinal driving mechanism, a spraying mechanism and a paint spraying mechanism arranged on the bearing frame 307.

[0038] The inner side of the bearing frame 307 is further provided with at least one recess, and a stain detection sensor is arranged in the recess. It should be noted that the inner side refers to the side opposite to the fan tower. The stain detection sensor is specifically an infrared sensor. The principle of detecting stains by using the infrared sensor is explained as follows:

[0039] The infrared sensor detects the characteristics of the object by emitting and receiving infrared rays. When infrared light shines on the surface of the object, part of the light is reflected back, and the sensor determines the situation of the object according to the intensity, wavelength, and other information of the reflected light. If the stain and the material of the object surface have differences in infrared absorption and reflection characteristics, the infrared sensor may detect such differences and indirectly detect the presence of the stain. For example, some stains may absorb more infrared light, resulting in a decrease in the intensity of the reflected light, and the sensor can capture this change. That is, during detection, by comparing the currently collected reflected light intensity with the originally recorded reflected light intensity without stains, it can be determined whether there is a stain.

[0040] It should be noted that the use of infrared sensors has the advantage of low cost, but cannot accurately identify the type of stain and other detailed information alone. Therefore, an image sensor can also be used instead of an infrared sensor to obtain information about the stain by identifying the collected image information. When an image sensor is used as a stain detection sensor, a corresponding image recognition algorithm is also needed, which will not be described in detail in this embodiment. The principle is briefly described as follows: the image recognition model is trained by using labeled classification training image data, and the effect of the trained image recognition model is judged by using the training data set. When the expected effect is achieved, the training is stopped. The cost of using an image sensor as a stain detection sensor is relatively high, but the stain recognition effect is better.

[0041] The structure of the load-bearing frame 307 is as follows: as shown in Figure 2 The load-bearing frame 307 is a half-circle structure, combined with the cylindrical base described above using the combination structure of the first assembly 1 and the second assembly 4. When the first assembly 1 and the second assembly 4 are disassembled, the ring groove is also divided into two. Since the load-bearing frame 307 is a half-circle structure, the drive wheel 3008 on the load-bearing frame 307 can be removed from the ring groove with an opening in the cross section. If the load-bearing frame 307 is a full-circle structure, it is difficult to remove it from the ring groove, which is not convenient for disassembly.

[0042] Since the load-bearing frame 307 is a half-circle structure, the load-bearing frame 307 has two ends, and the circumferential drive mechanism and the longitudinal drive mechanism are respectively fixed to the two ends of the load-bearing frame 307; the spraying mechanism and the paint spraying mechanism are fixed between the two ends of the load-bearing frame 307.

[0043] For a further understanding of the specific structure of the cleaning device 3 composed of the circumferential drive mechanism, the longitudinal drive mechanism, the spraying mechanism, the paint spraying mechanism, and the load-bearing frame 307, please continue to refer to Figure 2The circumferential driving mechanism comprises a driving motor 3007, a fixed column 3006 and a first mounting column 3004. The fixed column 3006 is fixedly arranged at one end of the load-bearing frame 307. More specifically, the side of the lower end of the fixed column 3006 is fixedly arranged at the end of the load-bearing frame 307. The two can be welded, but in order to facilitate disassembly, they can also be connected by bolts. The corresponding bolt connection structure is designed in a conventional manner, and will not be described here. The first mounting column 3004 is detachably connected with the upper end of the fixed column 3006, such as by threaded connection. The first mounting column 3004 is further provided with a first mounting hole. The first mounting hole is used for mounting a fixed plate 3005. The fixed plate 3005 is used for fixing a wiping cloth. That is, the wiping cloth on the fixed plate 3005 is driven by the first mounting column 3004 or the fixed column 3006 to move around the fan tower. Since it is necessary to control the contact between the wiping cloth and the fan tower, the fixed plate 3005 is fixed to the telescopic end of the electric telescopic device mounted in the first mounting hole. The contact between the wiping cloth and the fan tower is controlled by the telescopic end of the electric telescopic device. The electric telescopic device here can also be an electric telescopic cylinder. It should be noted that the first mounting column 3004 can also not be provided, and the fixed column 3006 can be extended.

[0044] The driving motor 3007 is connected with the lower end of the fixed column 3006, and can also adopt a detachable connection mode. The end of the driving rod of the driving motor 3007 is provided with a driving wheel 3008. That is, the driving wheel 3008 is rotated by the driving motor 3007. A rubber sleeve is arranged on the surface of the driving wheel 3008. The circumferential movement of the cleaning device 3 relative to the ring groove is driven by the friction between the rubber sleeve and the ring groove. In addition, in order to improve the accuracy of cleaning and maintenance of the stained area, the driving motor 3007 can adopt a servo motor, which can realize more accurate movement control.

[0045] The longitudinal driving mechanism comprises an electric telescopic cylinder and a second mounting column 303. The electric telescopic cylinder comprises a cylinder body 302 and a driving end 301. The cylinder body 302 is fixedly arranged on the load-bearing frame 307 at the other end opposite to the circumferential driving mechanism. The end of the driving end 301 is provided with a driving wheel 3008. The end of the cylinder body 302 opposite to the driving end 301 is fixedly arranged with the second mounting column 303. The end of the second mounting column 303 away from the cylinder body 302 is provided with a second mounting hole. The second mounting hole is used for mounting an electrically controlled spray head 305.

[0046] For the convenience of understanding the scheme, the electric telescopic cylinder is described as follows: the electric telescopic cylinder is a mechanical device for converting the rotary motion of an electric motor into linear reciprocating motion, which has the characteristics of compact structure, precise control, easy installation and the like. It is mainly composed of a cylinder body 302 and a telescopic rod (i.e. the driving end 301 in the embodiment), and the cylinder body 302 has a transmission mechanism. Since it is prior art, no detailed description will be given. Its control system usually uses PLC, motion controller or single-chip microcomputer to realize telescopic control. In the embodiment, the position of the telescopic end relative to the cylindrical base in the longitudinal direction is unchanged, so in the embodiment, the movement of the cylinder body 302 actually drives the load-bearing frame 307 to move longitudinally.

[0047] The spraying mechanism includes a water storage pressure tank 306 and a connecting pipe 304, the water storage pressure tank 306 is fixed between the two end portions of the load-bearing frame 307 and close to the longitudinal driving mechanism, and can be fixedly connected by bolts; the connecting pipe 304 is used to connect the water storage pressure tank 306 and the electrically controlled spray head 305.

[0048] The electrically controlled spray head 305 is a water spraying device that is intelligently controlled by an electric signal, and its structure mainly includes an execution mechanism, a water spraying assembly and auxiliary components. The execution mechanism is usually an electromagnetic valve or an electric valve. The electromagnetic valve drives the valve core to act by the magnetic force generated by the energization of the electromagnetic coil, to realize the on-off of the water flow, and is divided into normally closed type (off when power off, on when power on, commonly used in fire fighting scene) and normally open type (on when power off, off when power on, suitable for scene requiring emergency water flow cut-off). The electric valve realizes the accurate adjustment of the valve core by driving the transmission mechanism (such as screw, gear) through the motor. The water spraying assembly includes the nozzle (such as columnar, fan-shaped, mist-shaped nozzle) that determines the water spraying mode and the adjustable angle guide plate / rotation mechanism (the nozzle angle adjustment or 360° scanning water spraying is realized by the motor driving). The auxiliary components such as filter can filter impurities to prevent nozzle blockage, the manual emergency device is used for emergency manual operation, and the sealing assembly ensures that the connection is not water leakage.

[0049] The working principle is based on the linkage process of signal triggering, execution control and water spraying adjustment. In the signal triggering stage, the device can be started by the control instruction of the main controller of the device in the embodiment. In the execution control stage, the electromagnetic valve or the electric valve acts according to the electric signal: after the electromagnetic valve is energized, the electromagnetic force makes the valve core open to spray water, and after power off, the spring resets to close; the electric valve drives the valve core to move slowly through the motor, and realizes accurate flow control in combination with the position feedback sensor. In the water spraying adjustment stage, the fixed angle nozzle sprays water in the preset direction, and the adjustable angle nozzle changes the water spraying direction or range by the motor driving, and some models can also realize intermittent water spraying through the pulse type on-off electromagnetic valve to meet different water spraying requirements.

[0050] The paint spraying mechanism comprises a paint storage pressure tank 3003, a paint conveying pipe 3002, an electrically controlled paint spraying head 3001 and a support frame 3009; the support frame 3009 is fixed between the two end portions of the load-bearing frame 307 and close to the circumferential driving mechanism, and the electrically controlled paint spraying head 3001 is fixed to one end of the support frame 3009 away from the load-bearing frame 307; the paint storage pressure tank 3003 is fixed on the load-bearing frame 307, and the paint conveying pipe 3002 is used to connect the paint storage pressure tank 3003 and the electrically controlled paint spraying head 3001. The working principle of the electrically controlled paint spraying head 3001 is similar to that of the electrically controlled spraying head 305.

[0051] The above is the main mechanical structure part of the maintenance device. Since many electrically controlled devices are involved, it can be understood that the maintenance device should also include a main controller and a power supply device in terms of control. The main controller controls and receives information of the stain detection sensor, the driving motor 3007 and the electric telescopic cylinder, processes the information, obtains the position to be cleaned and the type of maintenance required. Since the movement data of the driving motor 3007 and the electric telescopic cylinder can accurately construct a coordinate system to determine the coordinate position of the stain area, the type of cleaning maintenance can be selected based on the type of stain, such as whether paint spraying or water spraying is required, and the intensity of water spraying. Of course, the electrically controlled spraying head 305 and the electrically controlled paint spraying head 3001 are controlled by the main controller.

[0052] It should be noted that since the paint and water are stored in the pressure tank, the opening degree of the electrically controlled spraying head 305 and the electrically controlled paint spraying head 3001 can control the intensity of the spray. Since the controllability of liquid spray decreases as the pressure decreases, a small pump can be provided in the pressure tank to pump out water or paint, which has better controllability. Of course, the pump is also controlled by the main controller.

[0053] The power supply device can use a wind turbine to supply power. In order to achieve energy diversity, as shown in Figure 7 An installation groove is formed on the outer arc surface of the first assembly 1, and an energy storage battery 6 is arranged in the installation groove. The energy storage battery 6 is used to supply power to the maintenance device. A solar energy collection device 5 is also arranged on the outer arc surface of the first assembly 1. As shown in Figure 3 The solar energy collection device 5 comprises a movable support 502 hinged to the outer arc surface of the first assembly 1, and a photovoltaic panel 501 hinged to the movable support 502. The photovoltaic panel 501 is electrically connected to the energy storage battery 6. The photovoltaic panel 501 converts solar energy into electrical energy and stores the electrical energy in the energy storage battery 6. Energy diversity is achieved.

[0054] Through the above description of the mechanical mechanism and the electric control device, it can be understood that the working principle of the maintenance device in the embodiment is as follows: first, the circumferential driving mechanism is controlled by the main controller to move circumferentially, so that the cleaning device 3 moves around the tower drum, that is, the stain detection sensor detects the stain on the annular surface of a section of the tower drum. When the stain is detected, the spraying direction of the electric control spraying head 305 is aligned with the stain area for spraying by controlling the longitudinal driving mechanism and the circumferential driving mechanism, and the spraying intensity and spraying time can be controlled according to the stain type; after spraying, the wiping cloth is moved to the spraying area by controlling the longitudinal driving mechanism and the circumferential driving mechanism, the wiping cloth is contacted with the surface of the tower drum by controlling the telescopic cylinder that drives the fixed plate 3005 of the wiping cloth to extend and retract, and then the wiping cloth is moved to wipe by controlling the longitudinal driving mechanism and the circumferential driving mechanism. After wiping, if it is judged that the stain area needs to be sprayed with paint in the early stage, the spraying direction of the electric control paint spraying head 3001 is aligned with the stain area for spraying by controlling the longitudinal driving mechanism and the circumferential driving mechanism. When the tower drum of this section is maintained, the longitudinal driving mechanism is controlled to move to another section of the tower drum, and the above steps are repeated. It should be noted that since water flows downward during spraying, the cleaning and maintenance work on the tower drum is actually performed from top to bottom.

[0055] In addition, it should be noted that the electric telescopic cylinder of the longitudinal driving structure has a limited telescopic length, so the maintenance device is mainly used for the tower drum maintenance of small and medium-sized wind turbines, and since the lower half of the tower drum is prone to accumulate stains (mainly due to ground dust, rainwater splashing soil, and rainwater washing dust from the top and accumulating in the lower part of the tower drum), it fully meets the maintenance needs of the tower drum of small and medium-sized wind turbines.

[0056] It can be seen that the maintenance device in the embodiment can accurately find the stain area by the stain detection sensor, and based on the detected stain area, the spraying mechanism in the cleaning device 3 sprays the stain area to remove the stain, and then the fixed wiping cloth wipes the sprayed area after the stain is removed, and then the paint spraying mechanism sprays paint for maintenance. The device improves the deficiency that the traditional cleaning device cannot realize paint spraying maintenance. Based on the device of the application, blind carpet cleaning and paint repair are avoided, resources, time cost and labor cost are saved, and the practicality and convenience of the device are stronger.

[0057] In addition, the maintenance device is designed in a modular manner, and the plurality of structural components are connected in a detachable manner, which is convenient to disassemble and transport.
