Description

Technical Field

[0001] This utility model relates to a solar street light, and more particularly to a solar street light with a modular solar panel structure. Background Technology

[0002] With the development of green energy technologies, solar streetlights have become widely used in public areas such as urban roads, rural streets, and scenic parks due to their advantages such as energy saving, environmental protection, no need for wiring, and wide applicability. Traditional solar streetlights generally include solar panels, batteries, controllers, and lamps. They charge the batteries through sunlight during the day and provide power for illumination at night, possessing good independent operation capabilities.

[0003] In existing technologies, solar panels typically employ an integrated, fixed installation structure. A common practice is to mount the solar panel on top of a light pole or near the light fixture, securing it with screws, brackets, or other means to ensure its stability and durability in outdoor environments. While this structure achieves basic functionality to some extent, it still has several drawbacks in actual use and maintenance, as detailed below.

[0004] First, existing solar streetlights generally lack a modular design concept. Solar panels, light poles, and lights are usually integrated as a whole, which lacks flexibility and makes it difficult to replace parts or perform standardized maintenance. For example, when a solar panel is damaged, due to its lack of independence, it often cannot be replaced individually and must be completely removed or replaced as a whole, resulting in low maintenance efficiency and increased operating costs.

[0005] Secondly, in existing solar streetlights, the solar panels are usually directly fixed to the light pole or bracket, and the overall installation structure is complex. Once the solar panel fails or is damaged, maintenance personnel need to disassemble multiple fastening components. The entire disassembly and assembly process is cumbersome and time-consuming, especially when operating in a high-altitude environment. This not only increases the difficulty of the operation, but also brings significant safety hazards.

[0006] Finally, some solar streetlights adopt a non-removable or integral structure design. When the solar panel is damaged, it often needs to be replaced along with the bracket or the entire upper structure. This not only increases the difficulty of maintenance, but also increases labor costs and material waste.

[0007] As mentioned above, these are the main drawbacks of traditional solar streetlights during use. Summary of the Invention

[0008] The technical solution adopted by this utility model is as follows: a solar street light, including a street light body (10), a solar panel unit (20) and a battery assembly (30), wherein the solar panel unit (20) is disposed on the top of the street light body (10) and the solar panel unit (20) is electrically connected to the battery assembly (30).

[0009] The street light body (10) includes a light pole (11), a mounting arm (12) and a light head (13), wherein the mounting arm (12) extends along the periphery of the top of the light pole (11).

[0010] The solar panel unit (20) includes several solar panels (40), wherein several solar panels (40) are detachably mounted on the mounting arm (12), and each solar panel (40) is electrically connected to the battery assembly (30).

[0011] The lamp head (13) is located on the side of the upper end of the lamp post (11), below the mounting arm (12), and is electrically connected to the battery assembly (30).

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention provides a solar street light that designs the solar panels as independent modular units, each of which can be installed and replaced individually. This solves the technical problem of traditional solar street lights lacking a modular structure and wasting resources by replacing the entire unit. This design not only improves maintenance flexibility but also facilitates standardized mass production and rapid maintenance in the future.

[0014] This utility model provides a solar street light with a detachable installation structure design, which allows the solar panel to be quickly disassembled and replaced when it malfunctions or is damaged, solving the problems of cumbersome disassembly and assembly and low maintenance efficiency of traditional solar street lights.

[0015] This utility model provides a solar street light that uses a plug-in connection method, making the installation and disassembly of solar panels quicker and easier, effectively reducing construction difficulty and labor costs, and solving the problems of complex installation structure and long construction period in the prior art.

[0023] like Figures 1 to 7 As shown,

[0024] A solar street light includes a street light body (10), a solar panel unit (20), and a battery assembly (30), wherein the solar panel unit (20) is disposed on the top of the street light body (10), and the solar panel unit (20) is electrically connected to the battery assembly (30).

[0025] The street light body (10) includes a light pole (11), a mounting arm (12) and a light head (13), wherein the mounting arm (12) extends along the periphery of the top of the light pole (11).

[0026] The solar panel unit (20) includes several solar panels (40), wherein several solar panels (40) are detachably mounted on the mounting arm (12), and each solar panel (40) is electrically connected to the battery assembly (30).

[0027] The lamp head (13) is located on the side of the upper end of the lamp post (11), below the mounting arm (12), and is electrically connected to the battery assembly (30).

[0028] In practical applications, multiple solar panels (40) are independently installed on the mounting arm (12) in a modular manner, and each solar panel (40) can be disassembled, replaced, or maintained individually. This modular design ensures that if any solar panel (40) is damaged, the other solar panels (40) can still work normally without affecting the continuous operation of the overall solar street light.

[0029] Meanwhile, each solar panel (40) is electrically connected to the same battery assembly (30) via independent electrical wires. The battery assembly (30) serves as a unified energy storage unit, used to centrally store the electrical energy output by all the solar panels (40) and provide the lighting power required by the lamp head (13). This design not only improves maintenance efficiency but also significantly enhances the reliability and energy utilization of the system.

[0030] like Figure 2 As shown, in specific implementation, several insertion holes (121) and several insertion outlet holes (122) are respectively opened on the upper and lower sides of the mounting arm (12). The insertion holes (121) and the insertion outlet holes (122) correspond one-to-one, and each insertion hole (121) is connected to the corresponding insertion outlet hole (122).

[0031] A connection channel (123) is formed between each set of the insertion hole (121) and the insertion outlet hole (122), wherein a stop flange (124) is provided in the connection channel (123), and the stop flange (124) protrudes from the edge of the insertion outlet hole (122).

[0032] like Figures 3 to 4 As shown, in a specific implementation, the solar panel (40) includes a mounting rod (41), wherein the mounting rod (41) is connected to the back of the solar panel (40).

[0033] The mounting rod (41) is a cylindrical structure with an outer wall (411) and a stop protrusion (412) on the outer wall (411).

[0034] In practice, the mounting rod (41) is inserted into the insertion channel (123) through the insertion hole (121), and the stop protrusion (412) abuts against the stop flange (124) at the insertion outlet hole (122).

[0035] During installation, the mounting rod (41) is inserted into the insertion channel (123) through the insertion hole (121) and extends along the direction of the insertion channel (123) to the insertion outlet hole (122) until the stop protrusion (412) abuts against the stop flange (124) at the insertion outlet hole (122) to complete the insertion positioning.

[0036] When the mounting rod (41) is inserted into the insertion channel (123), a stable limiting fit is formed between the stop protrusion (412) and the stop flange (124), effectively preventing the mounting rod (41) from sliding down or loosening due to gravity or external force. This structural design not only ensures that the installation process of the solar panel (40) is simple and efficient, but also greatly improves the stability and reliability after installation, which is beneficial for subsequent module replacement and quick maintenance operations.

[0037] A rubber ring (413) is also fitted on the outer side wall (411) of the mounting rod (41), and the rubber ring (413) is located above the stop protrusion (412).

[0038] In practice, the rubber ring (413) is positioned at the edge of the insertion hole (121) and fits against the wall of the insertion hole (121).

[0039] During installation, when the mounting rod (41) is inserted into the insertion channel (123), the rubber ring (413) fits tightly against the edge of the insertion hole (121) to form a tight buffer structure, which effectively improves the stability of the insertion connection and enhances the waterproof and dustproof performance of the overall structure.

[0040] like Figure 5 As shown, a wire channel (414) is provided through the inner side of the mounting rod (41).

[0041] The solar panel (40) is electrically connected to an electrical wire (42), which runs through the wire channel (414).

[0042] In practice, with the mounting rod (41) inserted into the insertion channel (123), the wire channel (414) passes through the insertion channel (123) formed between the insertion hole (121) and the insertion outlet hole (122), so that the electrical wire (42) extends from the insertion outlet hole (122) to the outside of the mounting arm (12) along the wire channel (414).

[0043] like Figure 6 As shown, the solar panel (40) is electrically connected to the battery assembly (30) via the electrical wire (42).

[0044] like Figure 7 As shown, the battery assembly (30) includes a battery (31) and a cable connector box (32), wherein the battery (31) is installed in the cable connector box (32), the cable connector box (32) is installed on the lamp post (11), and the cable connector box (32) is located below the mounting arm (12).

[0045] The cable junction box (32) has a wire inlet (321) on one side.

[0046] In practice, the electrical wire (42) passes through the inside of the mounting arm (12), then through the wire inlet (321) into the cable junction box (32), and is electrically connected to the battery (31).

[0047] In practice, the solar panel (40) is electrically connected to the lamp holder (13) via the battery (31).
