Abstract
Description
Technical Field
[0001] This utility model belongs to the field of solar street light technology, and in particular relates to a photovoltaic panel assembly for a solar street light. Background Technology
[0002] Solar streetlights are streetlights that use solar energy as their power source. They convert solar energy into electrical energy through photovoltaic panels, which is then stored in batteries to power the streetlights at night. Therefore, the size of the photovoltaic panel's power generation area is one of the factors that determines the duration of the streetlight's illumination.
[0003] Current solar streetlights typically use a single photovoltaic (PV) panel to generate solar power. This means that increasing the power output of the PV panel requires increasing its size. However, larger panels are more susceptible to damage during severe weather events such as strong winds and heavy rain, leading to damage to the solar streetlight. Therefore, there is an urgent need to research and develop a photovoltaic panel module for solar streetlights to address these issues. Utility Model Content
[0004] The present invention provides a photovoltaic panel assembly for a solar street light, the purpose of which is to solve the technical problems mentioned in the background art, such as the low power generation of the photovoltaic panel in the prior art due to the use of only one photovoltaic panel.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a photovoltaic panel assembly for a solar street light, comprising a support member; a first frame is obliquely fixed to the support member; a second frame and a third frame are respectively disposed above and below the first frame; the second and third frames are both parallel to the first frame, and their relative inner surfaces are slidably attached to the upper and lower surfaces of the first frame; photovoltaic panels parallel to the first frame are fixed to the inner sides of the first, second, and third frames; the second and third frames are connected by a driving member; the driving member can drive the second and third frames to move relative to each other.
[0007] As a preferred embodiment of this utility model, the support member includes a vertically arranged support cylinder; a U-shaped connecting frame is vertically fixed to the upper end of the support cylinder; both ends of the connecting frame are fixed to the middle arm of a U-shaped bearing frame; the bearing frame is inclined.
[0008] As a preferred embodiment of this utility model, limit strips are fixed on both opposite sides of the first frame, and the length direction of both limit strips is parallel to the length direction of the side of the first frame; the two limit strips are respectively fixed on both ends of the support frame; the opposite side of the second frame and the opposite side of the third frame slide against the opposite inner surface of the two limit strips.
[0009] As a preferred embodiment of this utility model, a pair of sliding grooves are provided on the opposite inner sides of the two limiting strips along the length direction; protruding posts are vertically fixed on the opposite sides of the second frame and the opposite sides of the third frame; the two protruding posts on the second frame are slidably inserted into one sliding groove on the two limiting strips; the two protruding posts on the third frame are slidably inserted into the other sliding groove on the two limiting strips.
[0010] As a preferred embodiment of this utility model, the driving component includes a pair of rotating shafts, both ends of which are rotatably connected to the two arms of the support frame; transmission blocks are fixed at both ends of the two rotating shafts; guide rods perpendicular to the rotating shafts are vertically fixed on one surface of each pair of transmission blocks; the two pairs of guide rods are respectively disposed on opposite sides of the first frame; sliding sleeves are slidably sleeved on each pair of guide rods; positioning blocks are rotatably connected to each pair of sliding sleeves; two positioning blocks on one rotating shaft are respectively fixed to the two ends of the upper edge of the second frame, and two positioning blocks on the other rotating shaft are respectively fixed to the two ends of the lower edge of the third frame.
[0011] As a preferred embodiment of this utility model, gears are fixedly sleeved on both of the rotating shafts; the two gears mesh with each other; a worm gear is fixedly sleeved on one of the rotating shafts; a worm is meshed on the worm gear; one end of the worm is coaxially fixed on the output shaft of a servo motor; the servo motor is fixed on the intermediate arm of the support frame.
[0012] This utility model has the following beneficial effects:
[0013] This invention installs a support component at the top of the solar street light pole. When solar power generation is needed using photovoltaic panels, a drive component moves the second and third frames apart, causing the second frame to move diagonally upwards towards the first frame and the third frame to move diagonally downwards towards the first frame. This exposes all the photovoltaic panels on the first, second, and third frames, allowing for solar power generation through the three photovoltaic panels. This effectively increases the power generation of the photovoltaic panels without increasing their size, extending the lighting time of the solar street light. In severe weather conditions such as storms, the drive component moves the second and third frames closer together, causing the first, second, and third frames to stack together. This reduces the stress area of the entire photovoltaic panel assembly, effectively ensuring the stability of the entire photovoltaic panel assembly.
[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1:
[0027] Please see Figure 1-3As shown, this utility model is a photovoltaic panel assembly for a solar street light, including a support member 1; a first frame 2 is obliquely fixed on the support member 1; a second frame 3 and a third frame 4 are respectively arranged above and below the first frame 2; the second frame 3 and the third frame 4 are both arranged parallel to the first frame 2, and the relative inner surfaces of the second frame 3 and the third frame 4 are respectively slidably attached to the upper and lower surfaces of the first frame 2; a photovoltaic panel 5 parallel to the first frame 2 is fixed on the inner side of the first frame 2, the inner side of the second frame 3, and the inner side of the third frame 4; the photovoltaic panel 5 is a conventional component in this field; the second frame 3 and the third frame 4 are connected by a driving member 6; the driving member 6 can drive the second frame 3 and the third frame 4 to move relative to each other. In use, the support 1 is installed at the top of the solar street light pole. When solar power generation is needed using the photovoltaic panels 5, the drive 6 drives the second frame 3 and the third frame 4 to move apart, causing the second frame 3 to move diagonally upward towards the first frame 2 and the third frame 4 to move diagonally downward towards the first frame 2. This exposes all the photovoltaic panels 5 on the first frame 2, the second frame 3, and the third frame 4, allowing solar power generation through the three photovoltaic panels 5. This effectively increases the power generation of the photovoltaic panels without increasing their size, extending the lighting time of the solar street light. In severe weather such as storms, the drive 6 drives the second frame 3 and the third frame 4 to move closer together, causing the first frame 2, the second frame 3, and the third frame 4 to stack together. This reduces the stress area of the entire photovoltaic panel assembly, effectively ensuring the stability of the entire photovoltaic panel assembly.
[0028] Example 2:
[0029] Based on Example 1, as follows Figure 2-4 and Figure 6As shown, the support member 1 includes a vertically arranged support cylinder 101; a U-shaped connecting frame 102 is vertically welded to the upper end of the support cylinder 101; both ends of the connecting frame 102 are welded to the middle arm of a U-shaped bearing frame 103; the bearing frame 103 is inclined; limit strips 201 are welded to the opposite sides of the first frame 2, and the length direction of the two limit strips 201 is parallel to the length direction of the side of the first frame 2; the two limit strips 201 are respectively bolted to the two ends of the bearing frame 103; the opposite sides of the second frame 3 and the opposite sides of the third frame 4 slide against the opposite inner surfaces of the two limit strips 201; the opposite inner surfaces of the two limit strips 201 are respectively bolted to the two ends of the bearing frame 103; A pair of sliding grooves 202 are provided along the length direction; protruding posts 7 are vertically welded to the opposite sides of the second frame 3 and the opposite sides of the third frame 4; the two protruding posts 7 on the second frame 3 are respectively slidably inserted into one sliding groove 202 on the two limiting strips 201, and the two protruding posts 7 on the second frame 3 are respectively set on both ends of the lower edge of the second frame 3; the two protruding posts 7 on the third frame 4 are respectively slidably inserted into another sliding groove 202 on the two limiting strips 201, and the two protruding posts 7 on the third frame 4 are respectively set on both ends of the upper edge of the third frame 3; the cross-section of the protruding post 7 along the length direction is square, and the opposite surfaces of the protruding post 7 are respectively slidably attached to the upper and lower surfaces of the sliding groove 202. In use, the support cylinder 101 is vertically bolted to the top of the lamp post. At this time, the tilt angle of the photovoltaic panel 5 is 45°. By designing the protruding column 7 to slide in the slide groove 202, the movement stroke of the second frame 3 and the third frame 4 can be limited, while ensuring the linear movement effect of the second frame 3 and the third frame 4.
[0030] Example 3:
[0031] Based on Example 2, as follows Figure 2-3 and Figure 5-7As shown, the driving component 6 includes a pair of rotating shafts 601, each end of which is rotatably connected to the two arms of the support frame 103; both ends of the two rotating shafts 601 are bolted to transmission blocks 602; one surface of each pair of transmission blocks 602 is vertically welded with guide rods 603 perpendicular to the rotating shafts 601; the two pairs of guide rods 603 are respectively disposed on opposite sides of the first frame 2; each pair of guide rods 603 is slidably fitted with a sliding sleeve 604; each pair of sliding sleeves 604 is rotatably connected to a positioning block 605; two positioning blocks 605 are rotatably connected to one rotating shaft 601. Positioning blocks 605 are welded to the upper edges of the second frame 3, and two positioning blocks 605 on the other shaft 601 are welded to the lower edges of the third frame 4. Gears 606 are keyed to both shafts 601. The two gears 606 mesh with each other. A worm gear 607 is keyed to one shaft 601. A worm 607 meshes with the worm gear 607. One end of the worm 607 is coaxially fixed to the output shaft of a servo motor 609. The servo motor 609 is bolted to the intermediate arm of the support frame 103. In use, the servo motor 609 drives the worm gear 607 to rotate, which in turn drives the two rotating shafts 601 to rotate synchronously in opposite directions via the worm wheel 607 and gear 606. This causes the angle between the guide rods 603 on the two rotating shafts 601 to gradually increase. Then, the sliding sleeve 604 and the positioning block 605 drive the second frame 3 and the third frame 4 to move apart, causing the second frame 3 to move diagonally upward toward the first frame 2 and the third frame 4 to move diagonally downward toward the first frame 2. This exposes all the photovoltaic panels 5 on the first frame 2, the second frame 3, and the third frame 4, effectively ensuring the performance of the photovoltaic panels 5.
