Description

Technical Field

[0001] This utility model relates to the field of municipal lighting facilities technology, and in particular to a solar street light. Background Technology

[0002] As human society develops, energy is becoming increasingly scarce, so various sectors are advocating energy conservation and environmental protection. As a result, renewable energy sources such as solar energy are being used more widely, and are now being used extensively in applications such as streetlights.

[0003] For example, Chinese patent application number 202021101168.9 discloses a solar-integrated street light with automatic cleaning of solar panels, including a light pole, a fixed tail seat fixedly installed at the upper end of the light pole, a main body profile fixedly installed at the upper end of the fixed tail seat, an antenna and an LED light source fixedly installed at the lower end of the main body profile, a bird guard fixedly installed at the upper edge of the main body profile, tracks fixedly opened at both ends of the main body profile, a water tank fixedly installed at the lower edge of the main body profile, and a first irregular block movably installed inside the tracks.

[0004] For example, Chinese Patent Application No. 201720292817.X discloses a solar lamp body and a solar street light. The solar lamp body provided by this utility model includes at least two sets of solar panels, a lamp, and a top plate and a bottom plate arranged opposite each other. A cavity is formed between the top plate and the bottom plate. At least one solar panel is arranged adjacent to another solar panel at an angle on the top plate and provides power to the lamp.

[0005] The main body of the street light housings in existing technologies is made of integral molding. Different sizes or styles require the development of a new large mold, which is costly. Moreover, the production stability of large profiles is relatively poor, and if any defect occurs, the entire unit is scrapped, resulting in significant waste. Furthermore, the rigidity of the existing structure makes maintenance and replacement operations inflexible. For example, disassembling heavy solar panels is time-consuming and laborious, and the current assembly method of solar panels is prone to short circuits or the accumulation of debris, which can affect the solar energy conversion efficiency. Summary of the Invention

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.

[0031] Examples, such as Figure 1-11As shown, a solar street light includes a solar panel 1, a lamp base for supporting the solar panel 1, and several lamp bodies 2. The lamp base includes a front base 31 and a rear base 32 assembled from front and rear sections. The lamp bodies 2 are mounted on the front base 31. Through the above-described basic design, the rear base 32 and the front base 31 are each made using a separate mold. This separation offers the advantage that the differences in the overall structure and size of the light are primarily found on the front base 31 where the lamp bodies 2 are mounted. For example, different styles or numbers of lamp bodies can be installed using the same mold, as long as the front base 31 is properly installed... The shape and size can be changed accordingly, while the rear base 32 remains unchanged. This separate mold allows for the use of a single mold for the rear base 32 to match multiple different styles of front bases 31. Different front bases 31 require different molds, but because the individual molds are smaller after the separation, they become smaller molds instead of a large mold. Therefore, only the small mold for the front base 31 needs to be changed. This small mold is low-cost, more controllable, and has a high yield rate. If the existing large mold were reopened, the cost would be high, the probability of problems would be greater, and the yield rate would be lower. Therefore, this front-rear splicing structure effectively reduces production costs and increases the yield rate. The front base 31 and rear base 32 are typically made of aluminum alloy and can be formed using aluminum alloy production molds. The solar panel 1 can use an existing solar panel structure and be embedded and assembled in the upper part of the overall structure formed by splicing the front base 31 and rear base 32.

[0032] Specifically, the front base 31 includes a front base plate 311 and a front support plate 312, a left front support plate 313, and a right front support plate 314 integrally connected to the upper surface of the front base plate 311. The front base plate 311 can be rectangular or approximately rectangular in shape. The front support plates 312, 313, and 314 are upright plates, and the front portions of the left and right front support plates 313 and 314 are integrally connected to the left and right portions of the front support plate 312, respectively. In this way, the front support plates 312 and 314... 313 and the right front support plate 314 form a U-shaped semi-enclosed structure with the opening facing backward. Correspondingly, the rear base 32 includes a rear bottom plate 321 and a rear support plate 322, a left rear support plate 323, and a right rear support plate 324 integrally connected to the upper surface of the rear bottom plate 321. The rear support plate 322, the left rear support plate 323, and the right rear support plate 324 form a U-shaped semi-enclosed structure with the opening facing forward. In this way, the two semi-enclosed structures form a rectangular area between the solar panel and the lamp base. This area is an internal heat dissipation space, and the upper side is covered by the solar panel 1. In this configuration, the left front support plate 313 and the left rear support plate 323 are positioned front-to-back, the right front support plate 314 and the right rear support plate 324 are positioned front-to-back, and the front bottom plate 311 and the rear bottom plate 321 are positioned front-to-back and fixedly connected. It is preferable that the front bottom plate 311 and the rear bottom plate 321 be fixed using a structure that facilitates easy assembly and disassembly. Initially, they can be manufactured separately and then assembled, which also facilitates future disassembly for repair or reuse if damaged. Alternatively, existing methods such as welding can also be used for fixing.

[0033] Regarding the front and rear fixing method, the following implementation method is provided: a front connecting post 301 extending frontally is integrally connected to the rear position of the upper surface of the front base plate 311, and a rear connecting post 302 extending frontally and cooperating with the front connecting post 301 is integrally connected to the front position of the upper surface of the rear base plate 321. The front connecting post 301 and the rear connecting post 302 are connected and fixedly joined front and rear. The structural design of the front and rear connecting posts strengthens the structure and facilitates connection. It is preferable to fix the front connecting post 301 and the rear connecting post 302 using a fixing method that is easy to disassemble and assemble. Of course, the number of front connecting posts 301 and rear connecting posts 302 is the same and they correspond one-to-one. Preferably, three or more pairs of front connecting posts 301 and rear connecting posts 302 are used and evenly spaced from left to right. Specifically, the front connecting post 301 includes a front base section 3011 integrally connected to the upper surface of the front base plate 311 on its lower side, and a front insertion section 3012 integrally connected to the rear end of the front base section 3011. The rear connecting post 302 has a splicing slot 3020 extending from front to rear for the front insertion section 3012 to be inserted rearward. The front base section 3011, the front insertion section 3012, and the rear connecting post 302 are fixed together by front and rear screws 3000 extending from front to back. The front base section 3011 and the rear connecting post 302 can have an arch-shaped cross-section, and the front insertion section 3012 can have a circular cross-section. The cylindrical structure allows the splicing slot 3020 to be a cylindrical groove, so that the front insertion section 3012 can be inserted into the splicing slot 3020 first to form a preliminary circumferential limit. After splicing, the overall structural strength and stability are better. Then, the three parts are connected and fixed together by front and rear screws 3000, which is very convenient and practical. Of course, the front base section 3011, the front insertion section 3012 and the rear connecting column 302 are all provided with threaded holes that are open from front to back and connected in sequence, so that the screws of the front and rear screws 3000 can pass through. The front and rear screws 3000 are screwed into the threaded holes of the three parts at the same time to achieve fixation. The structure is relatively simple and solid.

[0034] Furthermore, the left front support plate 313 and the left rear support plate 323 are positioned opposite each other and should be close together to ensure the compactness and sturdiness of the structure. A connecting rod can be integrally connected to the rear end of the left front support plate 313, and a corresponding slot can be formed at the front end of the left rear support plate 323. The two plates can then be joined and plugged in, eliminating the need for further locking mechanisms and making the joint even more robust. Similarly, the right front support plate 314 and the right rear support plate 324 can also form a corresponding plug-in structure to enhance assembly sturdiness.

[0035] Preferably, the front support plate 312, the left front support plate 313, the right front support plate 314, the rear support plate 322, the left rear support plate 323, and the right rear support plate 324 surround and form a rectangular area, and each support plate has a stepped support portion t at the top of the rectangular area. The rectangular area is the area mentioned above. This area provides space for heat dissipation and wiring. The wires on the back of the lamp body run through this area, including the wires of the solar panel. Among them, the stepped support parts t on the upper side of the six support plates are for supporting the periphery of the solar panel 1. Specifically, the stepped support parts t on the top of each support plate form a rectangular stepped groove for the solar panel 1 to be inserted. The periphery of the solar panel 1 is bonded and fixed to the stepped groove with sealant. The size of the stepped groove is slightly larger than the size of the solar panel 1, so a gap is formed around it. The gap is filled with sealant to achieve fixation. Existing waterproof sealant can be used. This structural design makes the periphery of the solar panel 1 more airtight and can keep the upper front panel of the solar panel 1 flat with the top surfaces of the six support plates: front support plate 312, left front support plate 313, right front support plate 314, rear support plate 322, left rear support plate 323, and right rear support plate 324. In this way, even if there is dust, leaves, bird droppings, or other debris on the solar panel 1, it will be automatically cleaned by rain or wind. In some existing technologies, the integral molding structure or the lack of optimization in the structure leads to problems with the wiring in the lamp body area, requiring the removal of the heavy solar panel 1 for maintenance. Therefore, instead of using glue to seal and fix the surrounding structure, some detachable clamping plates are used for sealing and fixing. However, this structure causes the solar panel 1 to be recessed and lower than the surrounding structure, making it difficult to clean accumulated debris and thus affecting solar energy conversion. In this embodiment, due to the optimization of the structure, maintenance does not require the removal of the solar panel 1. Basically, the problem is on the battery side. Based on the subsequent structural updates, maintenance and replacement can be carried out with simple operations.

[0036] Preferably, the lamp body 2 is installed on the front base plate 311. The lamp body 2 can be an LED lamp, and the number of lamps can be selected according to the needs. However, the light source part of the lamp body 2 is exposed downwards on the front base plate 311, while the back part of the lamp body 2 can be installed on the front base plate 311 in the existing way. The wires connected to the back of the lamp body 2 will be routed in the rectangular area between the solar panel 1 and the front base 31 and the rear base 32.

[0037] Furthermore, a power supply box 4 with an upward opening is provided at the rear of the lamp body 2, located below the lamp base and closed with the lamp base cover. The power supply box 4 can be a conventional upward-opening box, such as an approximately rectangular or approximately trapezoidal box, and can also be made of aluminum alloy. A battery 41 and a controller 42 are arranged in the power supply box 4. The battery 41 can be detachably mounted at the bottom of the power supply box 4 in the existing manner, while the controller 42 can be detachably mounted on the lower side of the rear base plate 321 and located in the upper area of ​​the power supply box 4 in the existing manner. More importantly, the upper front part of the power supply box 4 is hinged to the lamp base, and the rear support plate 322 is fixed to the rear part of the power supply box 4 by upper and lower screws 3400 extending vertically. This design makes maintenance and replacement more convenient, because the most common faults are in the structure of the power supply box 4, such as battery or controller problems. Therefore, during maintenance, simply remove the upper and lower screws 3400, and the lamp base can be flipped forward and upward around the hinge position and opened forward and upward in the power supply box 4. This allows you to see the internal space of the power supply box 4 and the lower part of the rear base plate 321, so you can check the battery and controller. If there is a problem, you can replace them. The solar panel is connected to the lamp base and flipped forward and upward with a lever, which is very easy and convenient, without having to remove the solar panel.

[0038] The specific hinge structure is designed as follows: A sloping pull plate 401 extending forward and upward is integrally connected to the upper front part of the power supply box 4. A first hinge bushing z1 with an axial direction in the left and right direction is integrally connected to the top of the sloping pull plate 401. A hinge window 400 is provided on the front bottom plate 311, which passes through vertically to allow the sloping pull plate 401 to be inserted and rotated. A second hinge bushing z2 corresponding to the first hinge bushing z1 in the left and right direction is integrally connected to the upper surface of the front bottom plate 311. A hinge shaft z3 is passed through the first hinge bushing z1 and the second hinge bushing z2, with the axial direction of the hinge shaft z3 in the left and right direction. A first hinge bushing z1 requires two second hinge bushings z2 spaced apart on the left and right sides. The first hinge bushing z1 is positioned at the left and right intervals between the two second hinge bushings z2. The three are connected by a hinge shaft z3. This connection is not fixed, so the hinge shaft z3 and at least one of the first hinge bushing z1 and the second hinge bushing z2 need to be in a rotatable fit with a gap. Here, the two second hinge bushings z2 form a hinge structure, and two sets are required, one on each side of the front base plate 311, to ensure structural stability. Correspondingly, the diagonal bracing plates 401 on the power supply box 4 also need to be formed on both the left and right sides. When the power box 4 is opened or closed, the inclined plate 401 is in a swinging state relative to the front base plate 311. However, since the first hinge bushing z1 on the upper part of the inclined plate 401 needs to enter the upper side of the front base plate 311 to cooperate with the second hinge bushing z2, a hinge window 400 is opened on the front base plate 311. On the one hand, the inclined plate 401 can extend into the upper part of the front base plate 311, that is, into the aforementioned rectangular area, and then swing with relative movement, thus providing a swinging space. In addition, during the design process, these two sets of hinge structures are set on the left and right sides of the front base plate 311. In this way, for example, the hinge shaft z3 on the left can be inserted from the left outer side of the front support plate 313 to the right, and then pass into the second hinge bushing z2 and the first hinge bushing z1 of the left set. The hinge shaft z3 can adopt a bolt structure. The front support plate 313 has a threaded hole that runs through the left and right sides. The hinge shaft z3 and the front support plate 313 are fixed structures with threaded connection, but they can rotate with the bushing. The screw head of the hinge shaft z3 can be exposed outside the front support plate 313.Of course, it's also possible to simply open a larger through hole in the front support plate 313, allowing the hinge shaft z3 to enter inwards. A bolt structure can also be used. The hinge shaft z3 and the second hinge bushing z2 are fixed with a threaded connection, while the first hinge bushing z1 is rotated within it. The bolt head can remain in or very close to the through hole in the front support plate 313, making it convenient to operate with a screwdriver on the outside of the lamp base. This facilitates the simultaneous removal of the entire lamp base and solar panel, as the problem might not be within the power box (although this probability is relatively small). For example, during inspection, if the battery, circuit board, and controller are all fine, then the entire structure outside the battery box needs to be removed. This is very convenient; simply remove the hinge shaft from the left side, and the lamp base and solar panel can be taken together to the factory or a designated repair shop for specialized repair. However, this situation is relatively rare; usually, it involves replacing the battery or controller.

[0039] Preferably, a cable management block 5 is integrally connected to the upper surface of the front base plate 311 for the passage of the wires of the lamp body 2. The cable management block 5 has several upward-facing cable management channels 50 for inserting the power supply wires. A wire clamping block 51 for pressing the wires downwards is detachably fixed above the cable management block 5. This design reduces the failure rate within the rectangular area and prevents wire pulling. The wires on the back of the lamp body will run within this area. The cable management channels 50 are C-shaped structures with upward-facing openings. After the wires are inserted and pressed and fixed by the wire clamping blocks 51, the wires cannot move, preventing pulling and increasing safety. Multiple cable management channels 50 can be formed on the cable management block 5, and the wire clamping blocks 51 can also be installed and fixed with screws, i.e., screws are simultaneously screwed downwards into both the wire clamping blocks 51 and the cable management block 5. Here, two cable management blocks 5 are set, and the passage direction of the cable management channels 50 on these two cable management blocks 5 is perpendicular. This way, a group of wires is pressed and clamped from two directions, making it more stable. Here's a brief overview of the basic wiring method. One key point is that the power supply box 4 is located behind the lamp base, forming a closed chamber by vertically connecting with the rear base plate 321. For wiring, several vertically extending wire holes y are created on the rear base plate 321. The lamp's wires run through the rectangular area and enter this chamber within the power supply box 4 via the wire holes y. They typically connect to the controller's discharge drive circuit. The battery 41, which is a rechargeable battery, connects to the controller's charging and discharge drive circuits via wires. The wires connecting the solar panel (front facing up) to the back pass through the rectangular area and then through the wire holes y, also entering the power supply box 4 and connecting to the controller's charging circuit. The controller then controls the solar panel to charge the battery. Once charged, the solar panel controls the discharge drive circuit to supply power to the lamp. This is the entire wiring and control logic, which is fairly standard. The lamp's wires are organized and secured using the cable management block 5, reducing the likelihood of problems. Similarly, the solar panel's wires can also be organized and secured using the cable management block 5, minimizing the risk of problems. Therefore, with this design, problems usually arise from the battery in the battery box or the controller, which may become faulty due to prolonged use. In such cases, the problem can be easily resolved by opening the box for inspection and replacement.

[0040] Preferably, the rear side of the power supply box 4 forms an arc-shaped mounting outer surface 44. A mounting sleeve 45 for mounting to a light pole is detachably connected to the mounting outer surface 44. Arc-shaped mounting plates 450, which abut against the mounting outer surface 44, are integrally connected to both sides of the mounting sleeve 45. The arc-shaped mounting plates 450 and the mounting outer surface 44 are fixed together by inclined screws 4500. The arc-shaped mounting plates 450 have arc-shaped mounting holes 4501 that curve downwards and backwards, allowing the screw rod of the inclined screw 4500 to pass through and enabling the position of the arc-shaped mounting plate 450 to be adjusted around the screw rod during installation. After fixing, the screw head of the inclined screw 4500 abuts against the back of the arc-shaped mounting plate 450. On the surface of the mounting outer surface 44, the diameter of the head of the beveled screw 4500 is larger than the left-right spacing of the arc-shaped mounting hole 4501. The arc shape is designed from bottom to top, facilitating the assembly and fixing of the mounting sleeve 45. This design also allows for adjustments to the mounting angle according to different lamp post structures, as long as the arc-shaped mounting hole 4501 moves upward or downward along the screw of the beveled screw 4500. During installation, the beveled screw 4500 can be passed through the arc-shaped mounting hole 4501 and partially screwed into the rear of the power supply box 4, with the screw head not pressing against the surface of the arc-shaped mounting plate 450. The positions of the arc-shaped mounting plate 450 and the mounting sleeve 45 can be adjusted and confirmed before tightening the beveled screw 4500. The mounting sleeve 45 can be a conventional cylindrical or frustoconical shape, with corresponding positioning holes for detachable fixing to the lamp post.

[0041] Furthermore, an anti-tipping support rod 6 is rotatably connected to the lower side of the rear base plate 321 for support within the power supply box 4 during maintenance. The anti-tipping support rod 6 can be understood as a support rod used when the hood of a car is opened during repairs, holding the hood in place to prevent it from falling over. Therefore, the anti-tipping support rod 6 can adopt the structural design of such a support rod in a car and be installed on the lower side of the rear base plate 321. It is generally a rotatable installation connection. When the light needs maintenance, the upper and lower screws 3400 are removed, the rear base plate 321 is lifted, and the light base and solar panel are flipped open around the battery box at the hinge position. The anti-tipping support rod 6 is then rotated to a standing position against the power supply box 4 for maintenance, which is very safe and labor-saving.

[0042] Through the various structural designs in this embodiment, the cost of the entire street light is effectively controlled, its safety and stability are improved, solar energy utilization is more effective, and some operations during use are more convenient and safer.

[0043] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
