[0043] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the utility model. Instead, they are only examples consistent with some aspects of the utility model as detailed in the attached claims.

[0044] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" or "laid on" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0046] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "multiple" and "several" is two or more, unless otherwise clearly and specifically defined.

[0047] In the prior art, it is necessary to manually lay down protective covers for photovoltaic modules to protect them. However, the timing of the start and end of hailstorms needs to be judged by the operation and maintenance personnel. In the event of sudden severe convective weather, the operation and maintenance personnel may fail to respond in time, which may damage the photovoltaic modules and reduce the life of the photovoltaic modules.

[0048] In order to solve the above technical problems, the utility model proposes the following technical ideas: Considering that manually laying the protective cover of the photovoltaic module may cause the operation and maintenance personnel to fail to respond in time and damage the photovoltaic module, thereby reducing the life of the photovoltaic module. The inventor thought of automatically laying the air bag without manual operation when encountering hail weather. When the radar instrument detects hail, the trigger controller starts the motor to drive the connecting rod to drive the reel to unfold the air bag, and starts the air pump to inflate the air bag; when the radar instrument detects that the hail disappears, the trigger controller starts the air pump to pump air into the air bag, and starts the motor to drive the connecting rod to drive the reel to retract the air bag. It can avoid damage to the photovoltaic module due to the operation and maintenance personnel's failure to respond in time when encountering sudden severe convective weather, thereby extending the life of the photovoltaic module.

[0057] The radar instrument (104) is installed on the top of the first airbag support (101) or the top of the second airbag support (102) and is used to detect hail.

[0058] Optionally, the radar instrument (104) includes at least one of the following: a laser radar and a microwave radar.

[0059] The controller (105), the motor (106) and the air pump (107) are installed on the support platform (103); the air pump (107) is connected to the air bag (108) through a pipeline; the motor (106) is connected to the reel (109) through a connecting rod; when the radar instrument (104) detects hail, the controller (105) is triggered to start the motor (106) to drive the connecting rod to drive the reel (109) to unfold the air bag (108), and the air pump (107) is started to inflate the air bag (108); when the radar instrument (104) detects that the hail disappears, the controller (105) is triggered to start the air pump (107) to exhaust the air bag (108), and the motor (106) is started to drive the connecting rod to drive the reel (109) to retract the air bag (108).

[0060] Optionally, the controller (105) is a single chip microcomputer or a microprocessor.

[0061] In this embodiment, a pressure sensor (115) is also included; the pressure sensor (115) is installed on one side of the surface of the photovoltaic module (100), and the pressure sensor (115) is communicatively connected with the air pump (107) for shutting down the air pump (107).

[0062] In this embodiment, a gear (116) is further included; the gear (116) is installed at both ends of the reel (109), and the motor (106) drives the connecting rod to rotate the gear (116) to drive the reel (109) to unfold or retract the air bag (108).

[0063] In the present embodiment, when the radar instrument (104) detects hail, a hail occurrence signal is sent to the controller (105), triggering the controller (105) to start the motor (106), and the motor (106) drives the connecting rod to rotate the gear (116) in the forward direction to drive the reel (109) to unfold the air bag (108), until the air bag (108) covers the photovoltaic module (100), and the motor (106) stops working; the air pump (107) is started to inflate the air bag (108) through the pipeline, and when the pressure sensor (115) determines that the pressure value reaches the preset pressure, an air pump shutdown signal is sent to the air pump (107), and the air pump (107) stops working.

[0064] In this embodiment, when the radar instrument (104) detects that the hail has disappeared, a hail disappearance signal is sent to the controller (105), which triggers the controller (105) to start the air pump (107) to evacuate the air bag (108) until the air in the air bag is exhausted and the air pump (107) stops working; the motor (106) is started to reversely drive the connecting rod to rotate the gear (116) to drive the reel (109) to retract the air bag (108).

[0065] It can be seen from the above embodiments that the protective device of the photovoltaic module includes a first airbag bracket, a second airbag bracket, a bracket platform, a radar instrument, a controller, a motor, an air pump and an air bag. When the radar instrument detects hail, the trigger controller starts the motor to drive the connecting rod to drive the reel to unfold the air bag, and starts the air pump to inflate the air bag; when the radar instrument detects that the hail disappears, the trigger controller starts the air pump to evacuate the air bag, and starts the motor to reverse and drive the connecting rod to drive the reel to retract the air bag. It can avoid damage to the photovoltaic module due to the untimely response of the operation and maintenance personnel in the event of sudden severe convective weather, thereby extending the life of the photovoltaic module. In addition, when the pressure sensor determines that the pressure value of the air bag reaches the preset pressure value, it sends a signal to shut down the air pump to the air pump, and the air pump stops working. Ensuring that there is enough air in the air bag to protect the photovoltaic module further extends the life of the photovoltaic module.

[0066] refer to Figure 2 , Figure 2 A schematic diagram of the structure of the photovoltaic module protection device provided by the embodiment of the utility model Figure 2 On the basis of the above embodiment, in this embodiment, the protection device of the photovoltaic module further includes:

[0067] A control cabinet (112); the control cabinet (112) is installed on the support platform (103), and the control cabinet (112) is connected to the radar instrument (104) for communication and is used to turn on or off the radar instrument (104).

[0068] Specifically, when the control cabinet (112) predicts that bad weather will occur, a radar instrument on signal is sent to the radar instrument (104) to turn on the radar instrument (104); when the control cabinet (112) predicts that the bad weather will disappear, a radar instrument off signal is sent to the radar instrument (104) to turn off the radar instrument (104).

[0069] The control cabinet (112) includes: a sensor controller (113) and an environmental sensor (114).

[0070] The sensor controller (113) is respectively connected to the radar instrument (104) and the environmental sensor (114) for communication; the sensor controller (113) is used to turn on or off the radar instrument (104).

[0071] In this embodiment, multiple environmental data are collected by the environmental sensor (114), and the multiple environmental data are sent to the sensor controller (113), and the sensor controller (113) predicts bad weather based on the multiple environmental data. When the sensor controller (113) predicts bad weather, it sends a radar instrument start signal to the radar instrument (104) to turn on the radar instrument (104); when the sensor controller (113) predicts that the bad weather disappears, it sends a radar instrument stop signal to the radar instrument (104) to turn off the radar instrument (104).

[0072] In this embodiment, the environmental sensor (114) includes at least one of the following: a temperature sensor, a humidity sensor, an air pressure sensor, a wind speed sensor, a gas sensor, and a light sensor.

[0073] It can be seen from the above embodiments that multiple environmental data are collected by the environmental sensor and sent to the sensor controller; the sensor controller analyzes the multiple environmental data to predict bad weather. When bad weather is predicted, the radar instrument is turned on to detect hail, and when the bad weather disappears, the radar instrument is turned off. Avoid the radar instrument from working for a long time, which will reduce the life of the radar instrument.

[0077] In this embodiment, when the radar instrument (104) detects hail, an image recorder start signal is sent to the image recorder (117). The image recorder (117) starts to shoot and record the air bag (108) to determine whether the air bag (108) is deployed and inflated after the hail appears. If the air bag (108) is not deployed, an early warning is issued to take emergency measures; when the radar instrument (104) detects that the hail disappears, an image recorder shutdown signal is sent to the image recorder (117) to shut down the image recorder (117).

[0078] It can be seen from the above embodiments that when the radar detects hail, the image recorder is triggered to start recording and detect whether the air bag is deployed. If not, an early warning is issued to take emergency measures. This avoids any problem with the controller, air pump, and motor that causes the air bag to fail to deploy and inflate, thereby damaging the photovoltaic module, and further prolongs the life of the photovoltaic module.
