Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module dust removal technology, and in particular to an automated photovoltaic device dust removal device based on vibration and its vibration control system. Background Technology

[0002] Solar photovoltaic (PV) power plants, as an important component of the renewable energy sector, have experienced rapid development and widespread adoption globally in recent years. However, the operation and maintenance of PV power plants, especially dust control, has become a key challenge affecting their efficiency and long-term stable operation. Solar PV power plants are typically built in environments such as deserts, coastlines, and dusty areas, facing challenges like strong winds and sandstorms that easily accumulate dust, thus impacting power generation efficiency.

[0003] Currently, the operation and maintenance of solar photovoltaic power plants is generally carried out through frequent manual cleaning or mechanical cleaning, which is costly and may damage the photovoltaic panels and reduce the lifespan of the modules if not handled properly.

[0004] Currently, automated cleaning of solar photovoltaic power plants is inefficient, costly, and cannot detect or assess the degree of dust coverage in a timely manner, making it impossible to accurately determine the timing of cleaning. This results in problems of over-cleaning and under-cleaning. Utility Model Content

[0005] To address the aforementioned issues, this invention provides a vibration-based automated photovoltaic device dust removal system and its vibration control system. This system can respond quickly, trigger automatically, and perform cleaning adaptively, overcoming the limitations of traditional manual and wet cleaning methods. It is suitable for use in large photovoltaic power plants that are difficult to access or in desert areas where water is scarce. It avoids the use of water in traditional cleaning methods, thus reducing the cost of water use and transportation.

[0006] This utility model provides an automated dust removal device for photovoltaic devices based on vibration, the specific solution of which is as follows:

[0007] The vibration-based automated photovoltaic device dust removal device is applied to a solar photovoltaic power station, which includes several photovoltaic power generation units composed of photovoltaic panels and photovoltaic modules.

[0008] The device includes a vibration control system, a vibration unit, and elastic components;

[0009] The vibration control system is connected to the vibration unit, which is placed on the photovoltaic panel; the vibration control system is connected to the photovoltaic module on the photovoltaic panel; and the elastic component is placed on the photovoltaic panel.

[0010] Furthermore, the elastic component is connected to the photovoltaic panel and the support frame on which the photovoltaic panel is located.

[0011] Furthermore, the elastic component is a spring, and multiple elastic components are provided, placed on the photovoltaic panel frame and connected to the support frame.

[0012] Furthermore, the vibration control system and the vibration unit are mounted on the frame on the side of the photovoltaic panel.

[0013] Furthermore, the vibration unit employs an eccentric wheel motor or a linear vibration motor.

[0014] This utility model also provides a vibration control system applied to the aforementioned vibration-based automated photovoltaic device dust removal device. The vibration control system includes a power supply module and a control unit. The input terminal of the power supply module is connected to the output terminal of the photovoltaic module, and the output terminal of the power supply module is connected to the vibration unit. An electronic switch device is provided between the output of the power supply module and the vibration unit. The electronic switch device is connected to the output of the control unit, and the control unit controls the on / off state of the electronic switch device.

[0015] Furthermore, the control unit includes a communication module, which is communicatively connected to the user terminal.

[0016] The communication module enables remote control of the control unit by the user terminal, allowing staff to send remote signals and control the on / off state of electronic switching devices.

[0017] Furthermore, the control unit includes a timing module.

[0018] The timing module enables periodic control of the on / off state of electronic switching devices, achieving automated vibration control.

[0019] Furthermore, the communication module is connected to the timing module.

[0020] The communication module enables remote user terminal to control the timing module, while the user terminal can also receive vibration data.

[0021] Furthermore, the power supply module also includes a step-down module, through which the power supply module provides power to the various modules of the control unit and the vibration unit.

[0022] The power module is connected to the photovoltaic module, which enables the vibration control system to be self-powered without the need for an external power input. The voltage output of the photovoltaic module has a unified standard, and the power module can provide the required rated voltage to each module in the vibration system through the step-down module, ensuring the stable operation of each module.

[0023] The beneficial effects of this utility model are as follows:

[0024] The device drives the vibration unit on the photovoltaic panel to perform physical vibration through a vibration control system, which can clean the photovoltaic panel without the use of water resources. This overcomes the limitations of traditional manual and wet cleaning methods. For large-scale photovoltaic power stations with a wide coverage area or photovoltaic power stations located in desert areas where water is difficult to access, it reduces the utilization and transportation costs of water resources. The device drives the vibration unit to vibrate through a communication module and a timing module, which can realize on-demand periodic vibration dust removal based on the environment, or real-time dust removal through remote control. This achieves rapid response and automatic triggering of dust removal, ensuring that the photovoltaic panel surface is always kept in the best condition and is not limited by severe weather conditions.

[0031] Example 1

[0032] Embodiment 1 of this utility model discloses a vibration-based automated photovoltaic device dust removal device, which is applied to a solar photovoltaic power station. The solar photovoltaic power station includes several photovoltaic power generation units composed of photovoltaic panels and photovoltaic modules.

[0033] like Figure 1 As shown, the details are as follows:

[0034] The device includes a vibration control system 2, a vibration unit 1, and an elastic component;

[0035] The vibration control system 2 is connected to the vibration unit 1, which is placed on the photovoltaic panel; the vibration control system 2 is connected to the photovoltaic module on the photovoltaic panel; and the elastic component is placed on the photovoltaic panel.

[0036] The vibration control system 2 drives the vibration unit 1 to vibrate, thereby causing the photovoltaic panel to vibrate and achieving dust removal from the photovoltaic panel.

[0037] The vibration control system 2 is connected to the photovoltaic module, and the system can operate stably without the need for external energy intervention.

[0038] In a preferred embodiment, the elastic component is connected to the photovoltaic panel and the support frame on which the photovoltaic panel is located.

[0039] In a preferred embodiment, the elastic component is a spring 3, and multiple elastic components are provided, which are placed on the photovoltaic panel frame and connected to the support frame;

[0040] The elastic component can also be other existing elastic devices, which are not specifically limited here;

[0041] Specifically, four springs 3 are provided, respectively located around the bottom side of the photovoltaic panel, connecting the photovoltaic panel and the corresponding support frame.

[0042] After the spring 3 physically vibrates the vibration unit 1, it avoids collisions between the photovoltaic panel and the support frame, preventing scratches or structural damage to the panel surface and protecting the sensitive photovoltaic coating and encapsulation materials. At the same time, the elastic component enables the photovoltaic panel to sway at a frequency lower than that of the vibration unit 1 after the vibration unit 1 vibrates, thereby enhancing the dust removal effect.

[0043] In a preferred embodiment, the vibration control system 2 and the vibration unit 1 are mounted on the frame on the side of the photovoltaic panel.

[0044] In a preferred embodiment, the vibration unit 1 is an eccentric wheel motor, a linear vibration motor, or other device that can generate vibration, without specific limitations.

[0045] Example 2

[0046] Embodiment 2 of this utility model discloses a vibration control system applied to the vibration-based automated photovoltaic device dust removal device described in Embodiment 1 above, such as... Figure 2 As shown, the details are as follows:

[0047] The vibration control system 2 includes a power supply module and a control unit. The input terminal of the power supply module is connected to the output terminal of the photovoltaic module, and the output terminal of the power supply module is connected to the vibration unit 1. An electronic switch device is provided between the output of the power supply module and the vibration unit 1. The electronic switch device is connected to the output of the control unit, and the control unit controls the on / off state of the electronic switch device.

[0048] In a preferred embodiment, the control unit includes a communication module, which is communicatively connected to the user terminal.

[0049] The communication module enables remote control of the control unit by the user terminal, allowing staff to send remote signals and control the on / off state of electronic switching devices.

[0050] On-demand dust removal can be achieved through remote control, meaning that the user sends a dust removal command and dust removal duration parameter through the communication module, and the vibrator immediately starts working to remove dust.

[0051] In a preferred embodiment, the control unit includes a timing module.

[0052] The timing module enables periodic control of the on / off state of electronic switching devices, achieving automated vibration control.

[0053] In a preferred embodiment, the communication module is connected to the timing module.

[0054] The communication module enables remote user terminal to control the timing module, while the user terminal can also receive vibration data.

[0055] Periodic dust removal can be achieved through the timing signal control of the timing module. That is, the timing module controls the vibration unit 1 according to the set dust removal cycle and dust removal time. The communication module is connected to the timing module, and the two parameters of dust removal cycle and dust removal time can be configured through the communication module.

[0056] Specifically, regular dust removal and on-demand dust removal can work simultaneously. That is, it is normally in the regular dust removal mode, and when it receives the on-demand dust removal command, the vibration will start working, and after it ends, it will still be in the regular dust removal mode.

[0057] In a preferred embodiment, the power supply module further includes a step-down module, through which the power supply module provides power to each module of the control unit and the vibration unit 1.

[0058] The power module is connected to the photovoltaic module, which enables the vibration control system 2 to be self-powered without the need for external power input. The voltage output of the photovoltaic module has a unified standard, and the power module can provide the required rated voltage to each module in the vibration system through the step-down module, ensuring the stable operation of each module.
