Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic component fixing, and in particular relates to a welding-free photovoltaic component fixing bracket. Background Art

[0002] Photovoltaic modules generally include photovoltaic cells, back panels, tempered glass, junction boxes, connectors and other structures. Traditional photovoltaic modules often use welding devices to complete the connection between multiple components during production. For example, a specified number of cells are connected in series through welding technology to form a cell string. At present, some photovoltaic modules do not use welding devices. For example, the connection between cells is completed by conductive glue, which is directly applied between the cells and solidified by pressure or temperature to form a stable electrical connection. Compared with photovoltaic modules made with welding devices, welding-free photovoltaic modules have many advantages, such as reducing the difficulty of repairing parts.

[0003] Welding-free photovoltaic modules generally need to be used with fixing devices. The fixing devices can fix the photovoltaic modules on roofs, ground and other scenes to ensure the stability and safety of the photovoltaic modules. The fixing devices can be adjusted to adjust the tilt angle of the photovoltaic modules. When the photovoltaic modules are used at home, in order to prevent the photovoltaic modules from being easily touched by people and consider other factors, the fixing devices generally fix the photovoltaic modules on the roof. In some cases, such as hail weather, hail may damage the photovoltaic modules. At this time, if the tilt angle of the photovoltaic modules can be adjusted so that the impact angle between the photovoltaic modules and the hail changes, the impact force and damage degree of the hail on the photovoltaic modules can be reduced. In this scenario, considering the installation position of the photovoltaic modules, the operator cannot quickly approach the photovoltaic modules and thus cannot quickly adjust the tilt angle of the photovoltaic modules.

[0034] 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 of 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.

[0035] Example 1

[0036] like Figures 1 to 5 As shown, the utility model provides a welding-free photovoltaic module fixing bracket, comprising:

[0037] The fixing assembly 100 is used to fix the photovoltaic assembly, and includes a supporting portion 110 and a rotating portion 120 rotatably connected to the supporting portion 110. When the rotating portion 120 is working, the rotating portion 120 is connected to the photovoltaic assembly;

[0038] The driving assembly 200 is detachably connected to the supporting portion 110 and the rotating portion 120 and is used to adjust the tilt angle of the rotating portion 120;

[0039] The control unit 1 is electrically connected to the driving component 200 and is used to control the operation of the driving component 200 .

[0040] When installing the photovoltaic module, the photovoltaic module can be detachably connected to the rotating part 120 by means of threaded connection or the like. Similarly, the supporting part 110 can be detachably connected to the roof or other positions by means of threaded connection or the like. During the period of use after the installation is completed, when the user needs to adjust the inclination angle of the photovoltaic module, the adjustment can be completed through the control part 1. The inclination angle mentioned in the present utility model generally refers to the inclination angle relative to the horizontal plane.

[0041] Optionally, the control unit 1 is configured as a controller; the drive assembly 200 may adopt existing devices such as a cylinder, an electric push rod, etc.

[0042] It is important to know that users generally have the need to adjust the tilt angle of photovoltaic modules. For example, in hail weather, the position of the sun may change. By adjusting the angle of the photovoltaic modules, the time that the photovoltaic modules face the sun can be increased. In addition, the impact angle between the photovoltaic modules and the hail can also be changed, thereby reducing the impact force and degree of damage of the hail on the photovoltaic modules.

[0043] By configuring the drive component 200 and the control unit 1, when the photovoltaic component and the fixing component 100 are installed on a roof or other location that is inconvenient for a user to approach, when the user needs to adjust the tilt angle of the photovoltaic component, the control unit 1 can be used to control the drive component 200 to quickly achieve this need, and it can avoid the user being injured (such as falling) due to being close to the installation location of the photovoltaic component, especially in some cases, such as in bad weather.

[0044] In the fixing assembly 100, the support portion 110 is a support structure, which raises the photovoltaic assembly to prevent it from directly contacting the ground, thereby reducing potential damage to the photovoltaic assembly caused by factors such as ground humidity, ground pollution, and small animal activities.

[0045] Optionally, the driving component 200 has an output end and a non-output end, the non-output end is detachably connected to the support portion 110, and the output end is detachably connected to the rotating portion 120. The support portion 110 can separate the driving component 200 from the ground to protect the driving component 200 to a certain extent.

[0046] It should be noted that, with respect to the connection relationships mentioned in the present invention, except for the fixed connection between two connected structures, all others can be regarded as detachable connections, such as connection by threaded connection or the like.

[0047] Example 2

[0048] In this embodiment, the driving component 200 includes two driving parts 210 distributed in parallel along the horizontal direction. The driving parts 210 are both detachably connected to the supporting part 110 and the rotating part 120. The driving parts 210 are both electrically connected to the control part 1, and the driving parts 210 are used to adjust the inclination angle of the rotating part 120.

[0049] Optionally, the driving part 210 is a driving structure, and existing devices such as a cylinder and an electric push rod may be used.

[0050] By configuring the driving assembly 200 to include a plurality of driving structures, it can be avoided that when a single driving structure fails to operate, the user must wait for maintenance personnel to perform maintenance before being able to adjust the tilt angle of the photovoltaic assembly remotely.

[0051] In some cases, the driving part 210 is configured as a cylinder, and its piston rod is connected to the rotating part 120 by means of threaded connection, clamping, etc. When a single driving part 210 fails and the tilt angle of the photovoltaic module needs to be adjusted, the user separates this driving part 210 and the rotating part 120, and the rotating part 120 is driven by another driving part 210, without waiting for maintenance personnel to perform maintenance.

[0052] Example 3

[0053] In this embodiment, a cover 2 is detachably mounted on the rotating portion 120 , and the cover 2 is used to protect the photovoltaic assembly in the circumferential direction of the photovoltaic assembly.

[0054] The cover 2 is used to protect the photovoltaic component in the circumferential direction of the photovoltaic component. For example, when the rotating part 120 and the cover 2 are both working, the cover 2 can be mounted on the outside of the photovoltaic component to protect the side of the photovoltaic component. Such a setting has many advantages. For example, it can prevent dust from accumulating on the surface of some parts of the photovoltaic component, and can also prevent some parts of the photovoltaic component from being damaged due to long-term contact with rain.

[0055] Example 4

[0056] In this embodiment, a plurality of ventilation holes 3 are provided on the cover 2, and the ventilation holes 3 are used to ensure that the heat generated by the photovoltaic module during operation can be dissipated in time.

[0057] The setting of the cover 2 may affect the heat dissipation of the photovoltaic module, while the ventilation holes 3 can ensure that the heat generated by the photovoltaic module during operation can be dissipated in time to avoid overheating of the photovoltaic module, thereby maintaining its normal operation and extending its service life.

[0058] The ventilation holes 3 can also be used as water outlet holes, and the number, size and distribution of the ventilation holes 3 can be adjusted according to actual conditions.

[0059] Example 5

[0060] In this embodiment, the cover 2 is configured as an elastic structure, and each part of the cover 2 can be deformed under the action of external force.

[0061] Optionally, the covering member 2 is configured as a covering film, and the covering film can be connected to the rotating part 120 by gluing, and the covering film can be made of various materials, such as polyurethane.

[0062] The cover 2 is configured as an elastic structure. With this configuration, the cover 2 can cover and protect photovoltaic components of different sizes in their circumferential direction. The space occupied by the cover 2 is small, and the gap between some parts of the cover 2 and the photovoltaic components can be easily adjusted, such as placing a polyethylene foam board between the cover 2 and the photovoltaic components, so as to facilitate heat dissipation.

[0063] Example 6

[0064] In this embodiment, a fixing member 4 is connected to the cover member 2, and the fixing member 4 can fix a part of the cover member 2 to fit the photovoltaic module.

[0065] When the cover 2 is in use, the fixing member 4 can fix part of the cover 2 to the photovoltaic module. For example, when the cover 2 is a covering film, the fixing member 4 can fix the end of the covering film that is not connected to the rotating part 120 to the photovoltaic module. At this time, the rotating part 120 and the cover 2 are enclosed to form a accommodating cavity, and the photovoltaic module is placed in the accommodating cavity.

[0066] Example 7

[0067] In this embodiment, the fixing member 4 is configured as a rubber ring.

[0068] The fixing member 4 can be configured as a variety of objects, such as an elastic band, a rubber band, or a rubber ring. Taking a rubber ring as an example, when the covering member 2 is a covering film, the rubber ring can be disposed on the inner side of an end of the covering film that is not connected to the rotating portion 120 .
