Description

Technical Field

[0001] The utility model relates to the technical field of generator set shell cleaning, in particular to a self-cleaning device for a wind power generator set shell. Background Art

[0002] Wind turbines are electrical equipment that converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs alternating current. Wind turbines are generally composed of wind rotors, generators (including devices), direction regulators (tail fins), towers, speed limit safety mechanisms, and energy storage devices.

[0003] The internal temperature of a wind turbine will rise during operation, and a heat dissipation device is installed inside. The generator casing also serves as a part of the heat dissipation structure. The wind turbine is exposed to the external environment for a long time. In some dusty environments, some dust will adhere to the casing for a long time, and a layer of mud will form over a long period of time, affecting the heat dissipation efficiency of the wind turbine. Since the existing generator casing is not equipped with a self-cleaning structure, manual wet cleaning is required regularly. Not only is the cleaning efficiency poor, but the safety is also low and accidents are prone to occur. Therefore, a self-cleaning structure is needed to clean the generator casing to ensure the heat dissipation efficiency of the casing and a clean and beautiful appearance. Summary of the invention

[0004] The purpose of the utility model is to provide a self-cleaning device for the casing of a wind turbine generator set to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a self-cleaning device for the casing of a wind turbine generator set for wind power generation, comprising a casing, a track, a cleaning structure, a tooth groove and a driving structure; the track is welded to the outer wall of the casing; the cleaning structure is slidably connected to the track, and the cleaning structure comprises a slide slidably connected to the track, a rotating rod rotatably connected to the top of the slide, and a cleaning brush inserted on the outer wall of the rotating rod; the tooth groove is opened on the outer wall of the casing; the driving structure is arranged on one side of the slide, and the driving structure comprises a gearbox welded to one side of the slide, a gear head plugged into the output port on one side of the gearbox, and a driving motor connected to the top of the gearbox by screws, the other end of the rotating rod is plugged into the output port on one side of the gearbox, and the gear head is meshed with the tooth groove.

[0006] By adopting the above technical solution, the speed change gear in the gearbox is driven to rotate by the driving motor, so that the rotation speeds of the rotating rod and the gear head are different. The rotation of the gear head can drive the slide to move on the track on the tooth groove. While moving, the high-speed rotating cleaning brush can clean the outer wall of the outer shell, thereby achieving the function of cleaning the dust on the surface of the outer shell while moving, preventing the problem of dust accumulation for a long time and being too thick, ensuring the normal heat dissipation rate of the outer shell, and eliminating the need for workers to clean, thereby avoiding the problem of dangerous accidents caused by workers cleaning.

[0007] Preferably, a controller is provided on the top of the gearbox, and a rain sensor is provided on the upper surface of the controller.

[0008] By adopting the above technical solution, by installing a controller and a rain sensor, when it rains and the rain sensor senses rain, the controller can perform active cleaning work alone outside the set working time of the device. Cleaning can be performed under the effect of wetting by rain, which can wash away stubborn dust, improve the effect of cleaning the outer shell, improve the heat dissipation efficiency, make the overall outer shell of the generator set clean and bright, and improve the appearance of the generator.

[0009] Preferably, the rails and the tooth grooves are of the same length, and the tooth groove is located below one of the rails.

[0010] By adopting the above technical solution, by installing the same rails and tooth grooves, the cleaning structure can be driven to move by the gear head under one of the rails, so as to achieve the same cleaning range as the rail, improve the linkage and practicality of the device, and ensure sufficient cleaning of the outer shell.

[0011] Preferably, the length of the track and the tooth groove is three quarters of the length of the outer wall of the shell, and the range of the track and the tooth groove is in the upper half of the shell.

[0012] By adopting the above technical solution, by setting the length of the track and the tooth groove to three-quarters of the circumference, the bottom-mounted support column cannot move to ensure smooth movement and cleaning. At the same time, it is difficult for the bottom outer wall of the shell to adhere to and absorb dust, and the effect on the heat dissipation efficiency of the shell is small. Therefore, setting the length to three-quarters can ensure heat dissipation while avoiding obstruction by the support column.

[0013] Preferably, the speed of the output port of the gearbox connected to the rotating rod is greater than the speed of the output port connected to the gear head, and the rotating shaft of the drive motor is plugged into the rotating head inside the gearbox.

[0014] By adopting the above technical solution, a drive motor can be used to drive the rotating rod and the gear head for rotation by utilizing the gearbox, so that the gear head can rotate at a low speed for slow movement cleaning, and the cleaning brush can rotate at a high speed to improve the cleaning effect, thereby reducing the use cost of the drive motor and improving the utilization rate of the equipment power.

[0015] Preferably, each circle of the upper brush of the cleaning brush is formed by a mixed connection of a plastic nylon brush and a cloth brush, and the cleaning brush and the outer wall of the shell are pressed against each other.

[0016] By adopting the above technical solution, the adsorbed dust can be quickly moved and dispersed by using a plastic nylon brush, and the fine dust after cleaning can be rotated and wiped by using a cloth brush to improve the cleaning effect of the cleaning structure. Under the action of squeezing the different bristles of the lower box, the cleaning effect can be better than that of a traditional single brush.

[0017] Preferably, the upper surface of the controller has a circular groove which is recessed inwardly, and the rain sensor is embedded in the bottom of the circular groove.

[0018] By adopting the above technical solution, a circular groove is set to install the rainwater sensor, and the circular groove can be used to collect rainwater, ensuring that the rainwater can quickly and accurately enter the sensing head of the rainwater sensor, thereby achieving efficient and accurate detection of rainwater conditions.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] The driving motor drives the speed change gear in the gearbox to rotate, so that the rotating rod and the gear head rotate at different speeds. The rotation of the gear head can drive the slide to move on the track on the tooth groove. While moving, the high-speed rotating cleaning brush can clean the outer wall of the shell, so as to achieve the function of cleaning the dust on the surface of the shell while moving, and prevent the problem of excessive accumulation of dust for a long time, thereby ensuring the normal heat dissipation rate of the shell. There is no need for workers to clean it, and the problem of dangerous accidents caused by workers cleaning is avoided.

[0021] By installing the controller and rain sensor, when it rains and the rain sensor senses rain, the controller can perform active cleaning work outside the set working time of the device alone. Cleaning can be performed under the effect of wetting by rain, which can wash away stubborn dust, improve the effect of cleaning the outer shell, improve the heat dissipation efficiency, make the overall shell of the generator set clean and bright, and improve the appearance of the generator.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The following is combined with Figure 1-5 The utility model is described in further detail. Example

[0030] See also Figures 1 to 5 The utility model provides an embodiment: a self-cleaning device for the casing of a wind turbine generator set for wind power generation, comprising a casing 1, a track 2, a cleaning structure 3, a tooth groove 4 and a driving structure 5, the track 2 is welded on the outer wall of the casing 1, the cleaning structure 3 is slidably connected to the track 2, the cleaning structure 3 comprises a slide 301 slidably connected to the track 2, a rotating rod 302 rotatably connected to the top of the slide 301 and a cleaning brush 304 inserted on the outer wall of the rotating rod 302, the tooth groove 4 is opened on the outer wall of the casing 1, the driving structure 5 is arranged on one side of the slide 301, the driving structure 5 comprises a gearbox 501 welded on one side of the slide 301, a gear head 502 plugged on the output port on one side of the gearbox 501 and a gear head 502 connected to the output port on one side of the gearbox 501 by screws The driving motor 503 at the top of the gearbox 501 and the other end of the rotating rod 302 are plugged into the output port on one side of the gearbox 501, and the gear head 502 is meshed with the tooth groove 4. The driving motor 503 drives the speed change gear in the gearbox 501 to rotate, so that the rotating rod 302 and the gear head 502 rotate at different speeds. The rotation of the gear head 502 can drive the slide 301 to move on the track 2 on the tooth groove 4. While moving, the high-speed rotating cleaning brush 304 can clean the outer wall of the shell 1, thereby cleaning the dust on the surface of the shell 1 while moving, preventing the problem of dust accumulating too thickly for a long time, ensuring the normal heat dissipation rate of the shell 1, and eliminating the need for workers to clean, thereby avoiding the problem of dangerous accidents caused by workers cleaning. Example

[0031] See also Figures 1 to 5A controller 504 is provided on the top of the gearbox 501, and a rain sensor 505 is provided on the upper surface of the controller 504. By installing the controller 504 and the rain sensor 505, when it rains and the rain sensor 505 senses rain, the controller 504 can perform active cleaning work alone outside the set working time of the device. Cleaning can be performed under the effect of rain, which can wash away stubborn dust, improve the effect of cleaning the outer shell 1, improve the heat dissipation efficiency, make the generator set outer shell 1 clean and bright as a whole, and improve the appearance of the generator. The track 2 and the tooth groove 4 have the same length, and the tooth groove 4 is located below one of the tracks 2. By installing the same track 2 and tooth groove 4, it can be below one of the tracks. The cleaning structure 3 is driven by the gear head 502 to move, and the cleaning range is the same as that of the track 2, so as to improve the linkage and practicality of the device and ensure sufficient cleaning of the shell 1. The length of the track 2 and the tooth groove 4 is three quarters of the length of the outer wall of the shell 1, and the range of the track 2 and the tooth groove 4 is in the upper half of the shell 1. By setting the length of the track 2 and the tooth groove 4 to three quarters of the circumference, the bottom installed support column cannot move to ensure smooth movement and cleaning. At the same time, it is difficult for the bottom outer wall of the shell 1 to adhere and absorb dust, and the heat dissipation efficiency of the shell 1 is less affected. Therefore, the three quarters length setting can ensure heat dissipation while avoiding the obstruction of the support column. Example

[0032] See also Figures 1 to 5 The output port speed of the gearbox 501 connected to the rotating rod 302 is greater than the output port speed connected to the gear head 502. The rotating shaft of the driving motor 503 is plugged into the rotating head inside the gearbox 501. By using the gearbox 501, a driving motor 503 can be used to drive the rotating rod 302 and the gear head 502 to rotate, so that the gear head 502 rotates at a low speed for slow moving cleaning, and the high-speed rotating cleaning brush 304 improves the cleaning effect, reduces the use cost of the driving motor 503, and improves the utilization rate of the equipment power. Each circle of the cleaning brush 304 is formed by a mixed connection of a plastic nylon brush and a cloth brush. The cleaning brush 30 4 is squeezed against the outer wall of the housing 1, and the adsorbed dust can be quickly moved and dispersed by using a plastic nylon brush, and the fine dust after being scattered and cleaned can be wiped by a cloth brush in a rotation manner to improve the cleaning effect of the cleaning structure 3. Under the action of the different bristles of the lower box under squeezing, the cleaning effect can be better than that of a traditional single bristle brush. The upper surface of the controller 504 has a circular groove that is concave inwardly, and the rain sensor 505 is embedded in the bottom of the circular groove. The rain sensor 505 is installed by setting the circular groove, and the circular groove can be used to collect rainwater to ensure that the rainwater can quickly and accurately enter the sensing head of the rain sensor 505, so as to achieve efficient and accurate detection of rainwater conditions.

[0033] Working principle: When in use, the internal control system of the generator sets the daily cleaning time for the driving structure 5, and drives the speed change gear in the gearbox 501 to rotate through the driving motor 503, so that the rotating rod 302 and the gear head 502 rotate at different speeds. The rotation of the gear head 502 can drive the slide 301 to move on the track 2 on the tooth groove 4. While moving, the high-speed rotating cleaning brush 304 can clean the outer wall of the outer shell 1, thereby achieving the effect of cleaning the dust on the surface of the outer shell 1 while moving. At the same time, a rain sensor 505 is installed using a separate controller 504. When it rains and the rain sensor 505 senses rain, the controller 504 can perform active cleaning work outside the set working time of the device alone, and clean under the effect of rain wetting, which can wash away stubborn dust and improve the effect of cleaning the outer shell 1.

[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
