Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, specifically to a photovoltaic module and a street light. Background Technology

[0002] With the increasing scarcity of traditional energy sources, the application of solar energy will become more and more widespread. Using solar energy for road lighting is economical compared to traditional streetlights because it is simple to install, requires no grid connection conversion, and eliminates the need for overhead lines and cable excavation.

[0003] However, since solar photovoltaic panels must be installed on high poles, how to withstand storms and ensure the safety of the facilities themselves and the surrounding area is a major and unavoidable issue in the development of solar streetlights. Currently, the potential safety problems caused by installing photovoltaic panels on the outside of the sleeve and then covering the entire streetlight pole are overcome by installing the photovoltaic panels on the top of the streetlight pole. However, since the photovoltaic panels are laid on the outer perimeter of the streetlight pole, the light-illuminated area of ​​the pole is very limited, resulting in low light utilization efficiency of the photovoltaic panels. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a photovoltaic module and street light, which solves the problem that while photovoltaic panels are installed on the outer periphery of current solar street lights, the light utilization rate of the photovoltaic panels on the back side is not high.

[0005] In a first aspect, the present invention provides a photovoltaic module comprising:

[0006] Support rods are arranged vertically at intervals, and adjacent support rods are provided with mutually cooperating first sliding grooves;

[0007] A photovoltaic panel is disposed between adjacent support rods and inserted into the first sliding groove. The photovoltaic panel is disposed on the light-facing surface of the photovoltaic module.

[0008] A baffle is disposed between adjacent support rods and inserted into the first sliding groove; the baffle is disposed on the back surface of the photovoltaic module.

[0009] End caps are disposed at both ends of the support rod, and the end caps are configured to cooperate with the support rod. The end caps have through holes.

[0010] As can be seen from the above technical solution, the photovoltaic module provided by this utility model, through the cooperation of the support rod and the end cap, allows the photovoltaic panel to be installed in a slot-type manner, which facilitates later maintenance. Compared with the photovoltaic modules formed by the current sleeve method, it simplifies the production cost of the photovoltaic module. By setting the photovoltaic panel only on the light-facing part of the photovoltaic module, the light utilization rate of the photovoltaic module can be improved and the cost can be reduced. The end cap is provided with a through hole, and the photovoltaic module is sleeved on the rod body based on the through hole, which improves the flexibility of the combination installation.

[0011] Optionally, the baffle is a glass plate, and a light strip is also provided on the support rod, with the light strip corresponding to the glass plate. By using a glass plate as the baffle, the backlight surface of the photovoltaic module can be utilized, allowing light to be emitted from the rod itself.

[0012] Optionally, the support rod further includes a second sliding groove, on which a bracket is provided for positioning the light strip. By forming the second sliding groove on the support rod, the light strip is fixed by the bracket and the second sliding groove. By improving the support rod, it can be used to install the light strip, and the rod body achieves lighting while simplifying the structure.

[0013] Optionally, the support rod further includes a third sliding groove, which is configured to cooperate with the adjacent support rods. A perforated plate is inserted into the third sliding groove. The perforated plate can be formed into a perforated pattern according to actual needs. The light beam from the light strip can pass through the perforated plate to form a corresponding pattern, meeting the needs of advertising and other purposes. It can also be used in conjunction with light strips to meet the needs of evening advertising.

[0014] Optionally, a positioning pin is provided through the end cap, and the bottom of the positioning pin is configured to cooperate with the end of the second sliding groove.

[0015] Optionally, the photovoltaic panel and the baffle are curved surfaces. Curved photovoltaic panels can further improve light utilization, while curved photovoltaic panels and baffles can also reduce wind resistance and dust accumulation.

[0016] Optionally, the system also includes a photovoltaic connector, which is electrically connected to the photovoltaic panel. The electrical energy generated by the photovoltaic panel is transmitted to the battery inside the pole body via the photovoltaic connector, thus completing energy storage.

[0017] Optionally, the inner side of the end cap is provided with a first positioning part and a second positioning part, which are configured to limit the photovoltaic panel / baffle. The adjacent first positioning parts are configured to limit the support rod.

[0018] Optionally, the outer side of the end cap is provided with a limiting boss and a limiting recess, and the photovoltaic modules are arranged together by the limiting boss and the limiting recess. This allows for the vertical stacking of multiple photovoltaic modules, saving installation space.

[0019] Secondly, the present invention provides a street light comprising any of the photovoltaic modules that may be implemented in the first aspect.

[0020] By adopting the above technical solution, this application has the following technical effects:

[0021] The photovoltaic module provided by this utility model uses a support rod and end cap to allow the photovoltaic panel to be installed in a slot-type manner, which facilitates later maintenance. Compared with the photovoltaic modules formed by the current sleeve method, it reduces the production cost of the photovoltaic module. By placing the photovoltaic panel only on the light-facing part of the photovoltaic module, the light utilization rate of the photovoltaic module can be improved and the cost can be reduced. The end cap has a through hole, and the photovoltaic module is sleeved on the rod body based on the through hole, which improves the flexibility of combination installation.

[0035] Example 1

[0036] like Figure 1-5 As shown, this embodiment provides a photovoltaic module, including support rods 1, photovoltaic panels 2, baffles 3, and end caps 4. The support rods 1 are arranged vertically at intervals, and adjacent support rods 1 are provided with mutually cooperating first sliding grooves 11; the photovoltaic panels 2 are disposed between adjacent support rods 1 and inserted into the first sliding grooves 11, and the photovoltaic panels 2 are disposed on the light-facing side of the photovoltaic module; the baffles 3 are disposed between adjacent support rods 1 and inserted into the first sliding grooves 11, and the baffles 3 are disposed on the back-lighting side of the photovoltaic module; the end caps 4 are disposed at both ends of the support rods 1, and the end caps 4 are cooperating with the support rods 1, and the end caps 4 have through holes 45.

[0037] Based on this, the photovoltaic panel 2 is installed by slotting through the cooperation of the support rod 1 and the end cap 4, which facilitates later maintenance. Compared with the photovoltaic modules formed by the current sleeve method, it simplifies the production cost of photovoltaic modules. By setting the photovoltaic panel 2 only on the light-facing part of the photovoltaic module, the light utilization rate of the photovoltaic module can be improved and the cost can be reduced. The end cap 4 is provided with a through hole 45, and the photovoltaic module is sleeved on the rod body based on the through hole 45, which improves the flexibility of the combination installation.

[0038] In one specific implementation, such as Figure 2 As shown, the photovoltaic module consists of three photovoltaic panels 2 and one baffle 3. Taking the Northern Hemisphere as an example, the photovoltaic panels 2 face the east, south and west directions respectively, which has a high light utilization rate. The baffle 3 faces the north. Since the light intensity in the north is not high, it reduces costs while improving the overall light utilization rate of the photovoltaic module.

[0039] Specifically, the baffle 3 is a glass plate, and a light strip 6 is also installed on the support rod 1, with the light strip 6 corresponding to the glass plate. By setting the baffle 3 as a glass plate and installing the light strip 6 inside the photovoltaic module, the street light pole body also achieves lighting function.

[0040] like Figure 2 As shown, the support rod 1 also includes a second sliding groove 12, on which a bracket 5 is provided. The bracket 5 is used to position the light strip 6. By forming the second sliding groove 12 on the support rod 1, the light strip 6 is fixed by the bracket 5 and the second sliding groove 12. By improving the support rod 1, it can be installed in conjunction with the light strip 6, and the rod body achieves lighting while simplifying the structure. The support rod 1 also includes a third sliding groove 13, which is provided adjacent to the support rod 1. A perforated plate 7 is inserted in the third sliding groove 13. The perforated plate 7 can be formed into a perforated pattern according to actual needs. The light beam of the light strip 6 can pass through the perforated plate 7 to form a corresponding pattern, meeting the needs of advertising and other purposes; at the same time, it can also be set in conjunction with the light strip 6 to meet the needs of evening advertising.

[0041] In one embodiment, the photovoltaic panel 2 and the baffle 3 are curved surfaces. The curved photovoltaic panel 2 can further improve the light utilization rate, while the curved photovoltaic panel 2 and the baffle 3 can also reduce wind resistance and reduce dust accumulation.

[0042] like Figure 1 As shown, it also includes a photovoltaic connector 9, which is electrically connected to the photovoltaic panel 2. The electrical energy generated by the photovoltaic panel 2 is transmitted to the battery inside the pole through the photovoltaic connector 9, completing energy storage. Taking three photovoltaic panels 2 in each photovoltaic module as an example, the three photovoltaic panels 2 in each photovoltaic module are connected through a one-to-three photovoltaic connector.

[0043] like Figure 1-2 As shown, photovoltaic connectors 9 extend from both the top and bottom of the photovoltaic module, and these connectors 9 are configured to work together. Specifically, [the following is an example / detail]. Figure 1 In this configuration, the male photovoltaic connector extends from the top of the photovoltaic module, while the female photovoltaic connector extends from the bottom of the photovoltaic module. Thus, the photovoltaic connectors arranged vertically can be connected to each other to achieve power transmission.

[0044] Optionally, the through hole 45 also forms a wiring section 451 for threading the photovoltaic connector 9.

[0045] like Figure 2 As shown, a positioning pin 8 is provided through the end cap 4, and the bottom of the positioning pin 8 is fitted with the end of the second slide groove 12.

[0046] like Figure 4 As shown, the inner side of the end cap 4 is provided with a first positioning part 41 and a second positioning part 42. The first positioning part 41 and the second positioning part 42 are configured to limit the photovoltaic panel 2 / baffle 3. Adjacent first positioning parts 41 are configured to limit the support rod 1. There is a certain gap between the first positioning part 41 and the second positioning part 42. The gap is configured to fit the photovoltaic panel 2 and the baffle 3 so that the photovoltaic panel 2 / baffle 3 can be locked into the gap to achieve the limiting. The first positioning part 41 is located on the outer edge of the end cap 4, and there is a certain interval between adjacent first positioning parts 41. When the end cap 4 and the support rod 1 are locked by the positioning pin 8, the two adjacent first positioning parts 41 limit the two sides of the support rod 1 to ensure structural stability.

[0047] like Figure 5 As shown, the outer side of the end cap 4 is provided with a limiting boss 43 and a limiting recess 44, and the photovoltaic modules are arranged in cooperation with each other through the limiting boss 43 and the limiting recess 44. This allows for the vertical stacking and installation of multiple photovoltaic modules, saving installation space. At the same time, the cooperation between the photovoltaic modules can prevent the photovoltaic panel 2 from shifting at an angle, which would affect the light-emitting area of ​​the photovoltaic panel 2 and ensure the light utilization rate of the photovoltaic panel 2.
