[0036] With the promotion of clean energy, photovoltaic power generation has seen rapid development. Photovoltaic power generation is generally deployed in sparsely populated areas with strong sunshine. These areas often have a continental plateau climate characterized by low rainfall, high winds, droughts, harsh weather, frequent sandstorms, and high levels of dust in the air. PV power stations are also often built in such areas, requiring the frequent disassembly of containerized inverters for inspection and maintenance. The dry air and high levels of dust at maintenance sites can easily generate static electricity during assembly, damaging the inverter module's PCB. Furthermore, the confined interior of containerized inverters makes assembly difficult.
[0037] In order to solve the above problems, the embodiment of the present application provides an outdoor dust-free maintenance platform. Through the arrangement of a box body, an air purification component and a fixing component, when maintenance is required, the parts to be inspected are placed inside the box body from the inlet and outlet, and the inlet and outlet are closed by a door body. The parts to be inspected are fixed using a fixing component, and the air purification component purifies the air inside the box body to filter out the sand and dust inside the box body to create a dust-free environment; the operator puts his hands through the two hand operation holes into the inside of the box body to perform maintenance and maintenance operations on the parts to be inspected; this avoids the sand and dust in the environment from entering the parts to be inspected during the maintenance process, causing the possibility of damage to the parts to be inspected, thereby improving the service life of the parts to be inspected.
[0038] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.
[0039] The present application provides an outdoor dust-free maintenance platform. Figure 1 and Figure 2 The outdoor dust-free maintenance platform includes a box body 100, an air purification component 200 and a fixing component 300.
[0040] The box body 100 has a cavity inside, and an inlet and outlet 110 is provided on the box body 100 for the parts to be inspected to enter and exit the cavity. The box body 100 is provided with a door body 400 for opening and closing the inlet and outlet 110. One side of the box body 100 is set as a transparent side 120, and two hand-operated holes 130 are provided on the transparent side 120. The air purification component 200 is set on the box body 100 to purify the air inside the box body 100, and the fixing component 300 is set in the cavity of the box body 100 for fixing the parts to be inspected.
[0041] In the following embodiments, the part to be repaired is an inverter module as an example. In other implementations, the part to be repaired may also be other devices that have dust-free requirements during the repair process.
[0042] A closed space is formed inside the box 100 , and the air inside the box 100 is purified by the air purification component 200 , so that a dust-free environment is formed inside the box 100 .
[0043] For example, the housing 100 is made of plastic to reduce its weight, facilitate its transport, and improve the adaptability of the device. The internal dimensions of the housing 100 are set to a rectangular shape with a length of 850 mm, a width of 600 mm, and a height of 550 mm. In other embodiments, the structural dimensions of the housing 100 can also be changed according to actual needs.
[0044] For example, the box body 100 may also adopt a steel frame structure to improve the strength of the box body 100 .
[0045] The transparent side 120 may be glass or a transparent plastic plate.
[0046] For example, the box body 100 may be configured to have four side surfaces and a top surface that are transparent, so as to facilitate observation of the situation inside the box body 100 .
[0047] The air purification device is installed on the top of the housing 100. This device is state-of-the-art and will not be described in detail here; it is sufficient to purify the air within the housing 100. The air purification device also has an exhaust function, which can remove dust accumulated in the inverter module during maintenance.
[0048] Among them, the inlet and outlet 110 is opened on the side wall adjacent to the hand-operated hole 130. The door body 400 can adopt any structure such as sliding, side-opening, flip-up and flip-down. In the embodiment of the present application, the top of the door body 400 is hinged on the box body 100, and the hinge axis of the door body 400 is in the horizontal direction. A handle is provided on the side of the door body 400 facing the outside of the box body 100 to facilitate opening the box body 100. When it is necessary to open the box body 100, the inlet and outlet 110 can be opened by pulling the handle and rotating the door body 400 upward. The door body 400 can automatically close the inlet and outlet 110 by gravity to prevent dust from entering the interior of the box body 100 due to forgetting to close the door body 400.
[0049] Furthermore, a sealing ring is provided on the door body 400 to seal the gap between the door body 400 and the inlet and outlet 110 , thereby reducing the possibility of sand and dust entering the box body 100 .
[0050] In some embodiments, reference Figure 2 The fixing assembly 300 includes a rotating member 310 and an electromagnet 320 . The electromagnet 320 is disposed on the rotating member 310 to adsorb the frame of the inverter module. The rotating member 310 is disposed in the box 100 to rotate the electromagnet 320 .
[0051] The electromagnet 320 is installed on the rotating part 310, and the inverter module is adsorbed on the electromagnet 320. On one hand, the inverter module frame is fixed to facilitate the disassembly and assembly of the internal structure of the inverter module; on the other hand, the inverter can also be rotated through the rotating part 310, which improves convenience and reduces the labor intensity of the operators.
[0052] In some embodiments, reference Figure 2 The rotating member 310 includes a turntable 311 and a rotating shaft 312 . The rotating shaft 312 is connected to the cavity of the box body 100 for rotation in a vertical direction. The turntable 311 is set on the rotating shaft 312 , and the electromagnet 320 is set in the turntable 311 .
[0053] The electromagnet 320 is embedded in the turntable 311. While fixing the inverter module frame, it can also adsorb disassembled bolts and other components on the turntable 311 where the electromagnet 320 is installed to prevent the bolts and other components from rolling freely.
[0054] In some embodiments, a placement slot 140 is opened in the box body 100 , and the turntable 311 is rotatably placed in the placement slot 140 , and the upper surface of the turntable 311 is flush with the inner bottom surface of the box body 100 .
[0055] The turntable 311 is rotatably connected in the placement groove 140 so that the upper surface of the turntable 311 is flush with the bottom surface inside the box 100, thereby avoiding the formation of steps and facilitating the placement of the inverter module on the turntable 311.
[0056] The electromagnet 320 is also provided with a regulator, which adjusts the magnetic force of the electromagnet 320 by adjusting the current of the electromagnet 320. The control part of the regulator can be set in the box 100 to facilitate operation by the operator.
[0057] In some embodiments, reference Figure 1 The outdoor dust-free inspection platform also includes a height adjustment component 500, which includes two first telescopic parts 510 and two second telescopic parts 520. The first telescopic parts 510 and the second telescopic parts 520 are both arranged at the bottom of the box 100 to adjust the height of the box 100.
[0058] The first and second telescopic members 510, 520 are mounted at the four corners of the bottom of the enclosure 100. By adjusting the length of the first and second telescopic members 510, 520, the height of the enclosure 100 can be adjusted to accommodate workers of varying heights and enhance operator comfort. Furthermore, when encountering uneven outdoor surfaces, the first and second telescopic members 510, 520 can be adjusted separately to maintain the enclosure 100 level, facilitating maintenance of the inverter module.
[0059] In some embodiments, the first telescopic member 510 is tilted in the vertical direction, the first telescopic member 510 is hinged on the box body 100 , and a telescopic rod 530 is provided between the first telescopic member 510 and the adjacent second telescopic member 520 .
[0060] The first telescopic member 510 is arranged at an angle, and there is an angle between the first telescopic member 510 and the vertical direction. The distance from the bottom of the first telescopic member 510 away from the box body 100 to the second telescopic member 520 is greater than the distance from the bottom of the first telescopic member 510 close to the box body 100 to the second telescopic member 520, so that the first telescopic member 510 extends forward to improve the stability of the box body 100.
[0061] At the same time, the first telescopic member 510 is hinged to the box body 100, with the hinge axis of the first telescopic member 510 extending horizontally. The first telescopic member 510 and the adjacent second telescopic member 520 are connected by a telescopic rod 530. When the height of the box body 100 is adjusted, the extension and contraction of the first telescopic member 510 simultaneously drives the telescopic rod 530 to extend and contract, and changes the inclination angle of the first telescopic member 510, thereby further improving the stability of the connection with the box body 100.
[0062] Exemplarily, the first telescopic rod 530 and the second telescopic rod 530 can both be electric push rods, hydraulic cylinders, or air cylinders, and can also be set as manual telescopic structures and fixed by bolts or other structures, which will not be described in detail here.
[0063] In some embodiments, a roller 600 is provided at the bottom of the telescopic rod 530 .
[0064] Two rollers 600 are installed at the bottom of the telescopic rod 530 so that the four corners of the bottom of the box body 100 are provided with rollers 600, so as to facilitate the movement of the entire platform and facilitate transportation. Among them, the rollers 600 are universal wheels, so as to improve maneuverability and timely brake fixation.
[0065] In some embodiments, reference Figure 1 and Figure 2 An electrostatic eliminator 700 is provided in the box 100 and is used to be connected to the inverter module to eliminate static electricity on the inverter module.
[0066] The static eliminator 700 is installed inside the housing 100 , and the elimination cable extending from the static eliminator 700 is used to be electrically connected to the inverter module to eliminate static electricity on the inverter module.
[0067] During the inspection and maintenance of the inverter module, static electricity may damage the IGBT module on the inverter module. Therefore, by electrically connecting to the static eliminator 700, static electricity on the inverter module is eliminated to reduce damage to the IGBT module.
[0068] In some embodiments, reference Figure 1 and Figure 2 A temperature and humidity sensor 800 is provided in the box 100 for detecting the temperature and humidity in the box 100. A display 900 is provided on the box 100. The display 900 is electrically connected to the temperature and humidity sensor 800 to display the temperature and humidity information detected by the temperature and humidity sensor 800.
[0069] The display 900 is integrated with a control module. An alarm is also electrically connected to the display 900. The temperature and humidity sensor 800 monitors the internal environment of the cabinet 100 in real time and displays the humidity and temperature information on the display 900. When the temperature and humidity inside the cabinet 100 exceed or equal to preset values, the controller inside the display 900 controls the alarm to sound an alarm, alerting the operator.
[0070] Furthermore, the electrostatic state of the inverter in the box 100 can also be detected and displayed on the display 900 .
[0071] In some embodiments, a flexible sealing sleeve is provided on the hand operation hole 130 to seal the hand operation hole 130 .
[0072] The flexible sealing sleeve is a rubber sleeve with an opening in the middle and is sheared into a tooth shape through the middle of the flexible sealing sleeve. When no one is operating, the flexible sealing sleeve closes the hand operation hole 130, and the toothed edge also closes the middle opening of the flexible sealing sleeve. During operation, the operator inserts both hands into the middle opening of the flexible sealing sleeve respectively, and makes the toothed edge contact the human arm to seal the gap between the arm and the flexible sealing sleeve, further reducing the entry of sand and dust into the box body 100, so as to maintain a dust-free environment in the box body 100.
[0073] An outdoor dust-free maintenance platform provided by an embodiment of the present application comprises a box 100, an air purification component 200 and a fixing component 300. When the inverter module needs to be repaired, the inverter module is placed into the box 100 from the inlet and outlet 110, and the inlet and outlet 110 are closed by the door 400. The inverter module is fixed using the fixing component 300. The air purification component 200 purifies the air in the box 100 to filter out the sand and dust in the box 100 and create a dust-free environment. The operator puts his hands through the two hand operation holes 130 and reaches into the box 100 to perform maintenance and repair on the inverter module. This prevents sand and dust in the environment from entering the inverter module during the repair process, thereby causing damage to the inverter and improving the service life of the inverter.
