Description

Technical Field

[0001] This utility model relates to the field of road infrastructure technology, and in particular to a photovoltaic street light. Background Technology

[0002] like Figure 5 The diagram shows a three-dimensional structure of an existing photovoltaic street light. As can be seen, the street light includes a mounting base plate 10, on which a light pole 1 is welded. A light head 13 is mounted on the upper end of the light pole 1, and a T-shaped component 11 is welded to the upper end of the light pole 1. A photovoltaic top plate 12 is mounted on the upper end of the T-shaped component 11 via screws. However, because the photovoltaic top plate 12 is fixed to the upper end of the T-shaped component 11, and the horizontal section of the T-shaped component 11 is tilted at a fixed angle, it is inconvenient to adjust the tilt angle of the photovoltaic top plate 12 according to the installation environment during actual installation. Utility Model Content

[0003] This utility model provides a photovoltaic street light to overcome the shortcomings of the prior art and solves the problem that existing photovoltaic street lights do not have the ability to adjust the tilt angle of the photovoltaic roof, thus having strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A photovoltaic street light includes a base plate, a pole welded to the base plate, an extended arm fixed to the upper end of the pole, a light mounted on the lower side of the extended arm, a photovoltaic panel mounted on the upper end of the pole, a cover plate welded to the upper end of the pole, an upper extension tube welded to the cover plate, a top cover welded to the upper end of the upper extension tube, a fixing screw connected to the top cover by threads, a connecting upper plate fixed to the fixing screw, the lower wall of the connecting upper plate tightly attached to the upper wall of the top cover, a connecting lower plate sleeved and welded to the lower end of the upper extension tube, a sleeve welded to the outer periphery of the connecting lower plate, the connecting upper plate welded to the inner wall of the sleeve, an arc-shaped plate welded to the upper end of the sleeve, an arc-shaped bottom shell fixed to the lower wall of the photovoltaic panel by multiple connecting screws, the outer wall of the arc-shaped bottom shell and the upper wall of the arc-shaped plate contacting each other, and the arc-shaped bottom shell and the arc-shaped plate having matching shapes and structures, multiple fixing holes opened on the arc-shaped bottom shell, at least one pair of fixing holes having locking screws inserted into them, the lower ends of the locking screws being threaded to the arc-shaped plate. This solution improves installation flexibility by setting an arc-shaped base shell on the photovoltaic panel, an arc-shaped plate on the sleeve, and multiple corresponding holes. During installation, the arc-shaped base shell and the corresponding holes are locked in place. Furthermore, during installation, the arc-shaped base shell and arc-shaped plate can be fixed first with locking screws before fixing the photovoltaic panel, thus facilitating on-site construction and installation.

[0006] Furthermore, the upper end of the extension tube is connected to a cable routing hole, which facilitates cable connection and also serves to protect the cable.

[0007] Furthermore, multiple notches are provided on the outer periphery of the connecting plate to facilitate the cable threading operation.

[0008] Furthermore, mounting holes are provided on the curved plate, located directly above the fixing screws. The mounting holes serve two purposes: first, to facilitate the installation of the fixing screws, and second, to facilitate the routing of cables.

[0009] Furthermore, side plates are welded to both sides of the arc-shaped bottom shell to enhance its structural strength.

[0010] Furthermore, the two ends of the arc-shaped bottom shell are formed with wing plates, and the connecting screws are inserted through the wing plates, which can provide a flat surface for the installation of photovoltaic panels and facilitate the installation operation.

[0011] Furthermore, a vertical groove is formed on the pole body, and an inner block is provided in the vertical groove. The outer shape of the inner block matches the structure of the vertical groove. A horizontal screw is connected to the inner block by a thread, and an inner end plate is fitted on the horizontal screw. The inner end plate is welded to the root of the outrigger. The setting of the vertical groove makes it convenient to add facilities such as billboards on the pole body, thereby expanding the diversity of applications.

[0012] Furthermore, the inner block and the vertical groove are in one of the following structures: T-shaped, dovetail-shaped, L-shaped, or C-shaped. This structural design facilitates the connection and fixation of the inner block.

[0013] The advantages of the above technical solution are:

[0014] This invention facilitates the adjustment of the tilt of the photovoltaic panel as needed, and is convenient for installation and construction. In addition, it enhances the versatility of its applications. Attached Figure Description

[0025] During the installation of the photovoltaic panel 43, the sleeve 30 is first fitted onto the upper extension tube 28, and then the sleeve 30 is fixed onto the upper extension tube 28 using fixing screws 33. After fixing, the arc-shaped bottom shell 39 is fixed onto the sleeve 30 using locking screws 38. During fixing, the tilt of the arc-shaped bottom shell 39 needs to be adjusted as needed.
