Description

Technical Field

[0001] The present invention relates to the technical field of street lamps, and in particular to a multifunctional solar street lamp. Background Art

[0002] With the promotion of smart cities and green environmental protection concepts, the function of street lamps is no longer limited to simple lighting, and more and more multifunctional street lamps have emerged. Modern multifunctional street lamps usually integrate multiple functional modules such as lighting, monitoring, display, charging piles, sensors, etc. to meet the management needs of different cities. These modular designs can be flexibly combined according to specific needs, improving the adaptability and maintainability of the equipment.

[0003] However, although there are some multifunctional street light systems in the prior art, there are still several technical problems: the existing multifunctional street lights mostly adopt a fixed installation method, and the installation and replacement of each functional module requires manual operation. The installation process is complicated and there are certain safety hazards. Especially in the process of high-altitude installation and maintenance, special equipment and personnel are required, which increases the maintenance cost and safety risks. Therefore, how to achieve rapid installation and disassembly of functional modules and simplify the operation process is an important challenge in the current street light design. Summary of the invention

[0004] In view of this, the present invention proposes a multifunctional solar street light, which can improve the safety and convenience of installation and disassembly of a multifunctional module.

[0005] The technical solution of the present invention is implemented as follows: The present invention provides a multifunctional solar street light, which includes: a lamp post, a photovoltaic panel, a power box and a lamp pole, the photovoltaic panel is fixedly installed on the top of the lamp post, the lamp pole is fixedly installed on one side of the lamp post, the power box is fixed on the side of the top of the lamp post, the photovoltaic panel is electrically connected to the power box, and also includes a lifting device and an extension base. The lamp post is hollow inside, the lifting device is arranged on the inner side of the lamp post, the extension base is located on the outer side of the lamp post, and the extension base is fixed on the driving end of the lifting device.

[0006] The lifting device is used to drive the expansion base to rise and fall. The expansion base is used to install multi-functional components.

[0007] In some embodiments, a spring wire is further included, wherein the output end of the spring wire is fixed to the surface of the expansion base, and the input end of the spring wire is electrically connected to the power box.

[0008] Since the expansion base can be raised and lowered, in order to achieve stable power supply and communication during the lifting process, a spring wire is set to provide electrical connection. At the same time, in order to make the output end of the spring wire more stable, its output end is fixed to the surface of the expansion base.

[0009] In some embodiments, an expansion board is further included, a surface of which is provided with a plurality of plug interfaces, the plug interfaces are electrically connected to the output ends of the spring wires, and the expansion board is fixed to the side of the expansion base.

[0012] Since there is a great safety risk when the spring wire moves up and down with the expansion base, in order to reduce the safety of the spring wire during movement and prevent the spring wire from being scratched by the outside world, a wire groove is set on the outside of the lamp post to wrap the spring wire and provide stretching and contraction movement space, and the sliding opening is used to provide sliding space for the output end of the spring wire.

[0013] In some embodiments, a terminal is further included, wherein the terminal is slidably disposed in the wire slot, the terminal is electrically connected to the output end of the spring wire, and the terminal is electrically connected to the expansion board through a patch cord.

[0014] The terminal is used to collect the output ends of the spring wire so that the end of the spring wire remains stable during the extension and retraction process, and the entire spring wire can be kept inside the wire slot. The terminal part is connected to the external expansion board through a patch cord. The corresponding number of patch cords can be selected to connect the terminal and the expansion board according to the number of connectors that need to be powered or communicated.

[0015] In some embodiments, the lifting device is a linear screw, and the extension base is fixedly mounted on a nut side of the linear screw.

[0016] In some embodiments, the number of the extended bases is at least two, and the plurality of extended bases are arranged in a circular array along the circumference of the lamp post.

[0017] According to the usage scenario of the multifunctional solar street light and the demand for multifunctional expansion, different numbers of expansion bases can be used, and multiple expansion bases can be set at different positions in the height direction.

[0019] The first expansion board can be used to provide more installation planes to meet the installation requirements of different multi-functional modules.

[0020] In some embodiments, the expansion base also includes a second expansion plate, which is hingedly mounted on a side of the base plate away from the lamp post, the hinge axis of the second expansion plate is vertically arranged, and the hinge axis of the second expansion plate and the hinge axis of the first expansion plate are respectively located on both sides of the base plate in the horizontal direction.

[0021] The second expansion board is used to further provide more installation planes.

[0022] In some embodiments, the extension base also includes a limit plate, which is hingedly mounted on a side of the base plate away from the lamp post, and the hinge axis of the limit plate is horizontally arranged.

[0031] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0033] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0034] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0035] In the prior art, multifunctional street lamps are usually customized on street lamp poles. For example, corresponding brackets or frames are set at different heights and positions to install corresponding functional modules. For example, a cantilever is set on the top side to suspend a surveillance camera, and a hanging arm is set on the middle side to install a smart screen or a slogan board. Although street lamps of this design can provide more functional applications, when the customization requirements change, this fixed design structure is difficult to change at will. At the same time, this type of street lamp structure is extremely difficult to maintain when the functional module fails or needs maintenance, requires high-level operations by personnel, has a long maintenance cycle, and is costly.

[0036] In order to solve the shortcomings of these fixed-design multifunctional street lamps, the inventor proposed a solar street lamp with a multifunctional modular structure that can be lifted and lowered.

[0037] like Figure 1 As shown, combined Figure 2-4 The multifunctional solar street light of the present invention comprises: a lamp post 1, a photovoltaic panel 2, a power box 3 and a lamp pole 4, the photovoltaic panel 2 is fixedly installed on the top of the lamp post 1, the lamp pole 4 is fixedly installed on one side of the lamp post 1, the power box 3 is fixed on the top side of the lamp post 1, the photovoltaic panel 2 is electrically connected to the power box 3, and also comprises a lifting device 5 and an extension base 6, the lamp post 1 is hollow inside, the lifting device 5 is arranged on the inner side of the lamp post 1, the extension base 6 is located on the outer side of the lamp post 1, and the extension base 6 is fixed on the driving end of the lifting device 5.

[0038] As shown in the figure, the interior of the lamp post 1 is hollow along the axial direction to form an installation cavity for accommodating the lifting device 5. The extended base 6 is fixed to the driving end of the lifting device 5 and is located on the outside of the lamp post 1. The lifting device 5 is driven to rise and fall, thereby driving the extended base 6 to rise and fall. The extended base 6 is used to provide a mounting surface to install different functional modules. The extended base 6 has mounting holes for installation, which is convenient for quick installation and docking.

[0039] The power box 3 is used to receive electric energy from the municipal power supply and from the photovoltaic panel 2, and transmit the electric energy to the lamp pole 4 and the expansion base 6, so as to power the street lamp and the functional module.

[0040] In some embodiments, a spring wire 7 is also included, wherein the output end of the spring wire 7 is fixed on the surface of the expansion base 6 , and the input end of the spring wire 7 is electrically connected to the power supply box 3 .

[0041] In the above embodiments, the spring wire 7 is used to transmit electrical energy and signals. Since the expansion base 6 will be raised and lowered according to the use and installation requirements, the spring wire 7 is used to meet the up and down movement requirements. At the same time, in order to make it easier to power on the multi-function module after being installed on the expansion base 6, the output end of the spring wire 7 is fixed to the surface of the expansion base 6.

[0042] In some embodiments, an expansion board 8 is also included. A plurality of plug ports 81 are disposed on the surface of the expansion board 8. The plug ports 81 are electrically connected to the output ends of the spring wires 7. The expansion board 8 is fixed to the side of the expansion base 6.

[0043] The expansion board 8 is used to provide a standardized plug interface. The expansion board 8 can be used to quickly connect electricity and communication to the functional modules installed on the expansion base 6, making it more convenient for the rapid removal and installation of the functional modules, which is beneficial to reducing the difficulty and cost of maintenance and improving maintenance efficiency.

[0044] In some embodiments, a wire groove 9 is further included. The wire groove 9 is fixed to the side of the lamp post below the power box 3. A sliding opening 91 is provided on one side of the wire groove 9 close to the expansion base 6. The spring wire 7 is arranged in the wire groove.

[0045] In the above embodiment, the wire groove 9 is used to limit and protect the spring wire 7, so that the extension and retraction movement of the spring wire is always maintained inside the wire groove 9, which is beneficial to improving the aesthetics of the street lamp. The sliding opening 91 is used to provide a connection between the spring wire 7 inside the wire groove and the external expansion base 6 or expansion plug-in board 8.

[0046] In some embodiments, a terminal 10 is further included, wherein the terminal 10 is slidably disposed in the wire slot 9 , the terminal 10 is electrically connected to the output end of the spring wire 7 , and the terminal 10 is electrically connected to the expansion board 8 via a patch cord.

[0047] In the above embodiments, since the deformation of the body of the spring wire 7 is relatively large during the stretching and contraction process, the deformation process of the spring wire 7 arranged in the wire slot 9 in this case is likely to cause a large friction between the spring wire 7 located at the sliding opening 91 and the wire slot 9, which is not conducive to the stability of the spring wire 7. Therefore, a terminal 10 is provided to fix the output end of the spring wire 7 so that the main body of the spring wire 7 is located in the wire slot 9. At the same time, when the terminal 10 slides in the wire slot 9, it can be guided by a guide structure to maintain the sliding stability of the terminal 10, and then the terminal 10 and the external functional module or expansion board 8 are connected by a connector. Such a structure can greatly improve the structural stability of the wire slot 9 and the spring wire 7 located in the wire slot 9 as well as the stability and reliability of power transmission.

[0048] In some embodiments, the lifting device 5 is a linear screw, and the extension base 6 is fixedly mounted on the nut side of the linear screw.

[0049] Using a linear screw as the lifting device 5 not only has the advantages of low energy consumption and simple structure, but also can achieve position locking. The nut of the linear screw rises and falls during the rotation of the screw. Therefore, by installing the extended base 6 on the side of the nut, the extended base 6 can be driven up and down.

[0050] In some embodiments, the number of the extended bases 6 is at least two, and the plurality of extended bases 6 are arranged in a circular array along the circumference of the lamp post 1 .

[0051] In the above embodiments, considering that different functional modules have certain differences in volume, installation method, installation instructions, etc., one extension base 6 may not be able to meet the multi-functional load. In order to improve the functional scalability of the street lamp, the number of extension bases 6 is set to at least two, so that the installation of functional modules in different positions and directions can be met. It should be understood that the extension bases 6 at different positions can have differences in height direction, so as to meet the installation requirements of different heights. According to different installation requirements, different adapter plates can also be further installed on the extension base 6 to meet different installation requirements.

[0052] At the same time, when the plurality of extension bases 6 are pressed against the circumferential array, moment balance can be achieved to avoid damage to the lifting device 5. For example, load blocks can be installed on different extension bases 6 to ensure that the load weights on different extension bases 6 remain consistent.

[0053] In some embodiments, the extension base 6 includes a bottom plate 61 and a first extension plate 62. The bottom plate 61 is vertically arranged, and the side of the bottom plate 61 close to the lamp post 1 is fixedly connected to the driving end of the lifting device 5. The first extension plate 62 is hingedly installed on the side of the bottom plate 61 away from the lamp post 61, and the hinge axis of the first extension plate 62 is vertically arranged.

[0054] In the above embodiment, the first expansion board 62 can be rotated to be completely fitted with the bottom board 61, and a self-locking shaft can be used between the first expansion board 62 and the bottom board 61 to achieve angle locking between the first expansion board 62 and the bottom board 61. The first expansion board 62 provides more mounting surfaces and mounting angles, which is conducive to providing more adaptable expansion of functional modules.

[0055] In some embodiments, the extension base 6 also includes a second extension plate 63, which is hingedly mounted on a side of the bottom plate 61 away from the lamp post 61, and the hinge axis of the second extension plate 63 is vertically arranged, and the hinge axis of the second extension plate 63 and the hinge axis of the first extension plate 62 are respectively located on both sides of the bottom plate 61 along the horizontal direction.

[0056] In the above embodiments, the second expansion plate 63 is used to further increase the installable surface of the expansion base 6. The second expansion plate 63 and the first expansion plate 62 are of split-type design. The second expansion plate 63 can be rotated to fit with the first expansion plate 62, or can be rotated to be perpendicular to the bottom plate 61. The second expansion plate 63 can also be hinged to the bottom plate 61 by a self-locking shaft to achieve adjustable and locking rotation angles.

[0057] In the above embodiments, a protruding limit block can be provided on one side of the first extension plate 62 close to the base plate 61 and on one side of the second extension plate 63 close to the base plate 61 to limit the rotation angle. Specifically, when the first extension plate 62 or the second extension plate 63 is rotated until the limit block abuts against the side of the base plate 61, the first extension plate 62 and the second extension plate 63 reach the end of the rotation stroke relative to the base plate 61, that is, they are limited.

[0058] In some embodiments, the extension base 6 also includes a limit plate 64, which is hingedly mounted on a side of the bottom plate 61 away from the lamp post 1, and the hinge axis of the limit plate 64 is horizontally arranged. When the first extension plate 62 and the second extension plate 63 are rotated to be perpendicular to the bottom plate 61, the limit plate 64 can be rotated between the first extension plate 62 and the second extension plate 63 and the limit plate 64 is simultaneously abutted against the surface of the first extension plate 62 and the second extension plate 63 at both ends in the horizontal direction.

[0059] In the above embodiments, the limit plate 64 is used to assist in limiting the first extension plate 62 and / or the second extension plate 63. Through the supporting effect of the limit plate 64 and the limiting effect of the extreme rotation angle of the first extension plate 62 and the second extension plate 63, the position of the first extension plate 62 and / or the second extension plate 63 is locked.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
