Description

Technical Field

[0001] The present application relates to the technical field of new energy lamps, and in particular to a solar street lamp that significantly improves the efficiency of sunlight utilization. Background Art

[0002] Solar street lights are powered by crystalline silicon solar cells, stored in maintenance-free valve-regulated sealed batteries (gel batteries), and illuminated by ultra-bright LEDs controlled by intelligent charge and discharge controllers. They are designed to replace traditional public electric streetlights. They require no cabling, no AC power supply, and no electricity bills. They utilize a DC power supply and photosensitive control, offering excellent stability, long lifespan, high luminous efficiency, easy installation and maintenance, high safety, energy conservation, environmental protection, and economical practicality. They are now widely used in urban main and secondary roads, residential areas, factories, tourist attractions, parking lots, and other locations.

[0003] However, most existing solar street lights are fixed and cannot adjust according to changes in the angle of incidence of the sun. Theoretically, when sunlight is perpendicular to the solar panel, the solar panel absorbs solar energy most efficiently. However, the solar panels of traditional solar street lights are not movable. As a result, the solar panel cannot absorb solar energy at its maximum efficiency when the angle of incidence of the sun changes, resulting in low operating efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a solar street light that greatly improves the efficiency of sunlight utilization, solving the problem that the solar panel cannot change with the change of the sun's incident angle, cannot absorb solar energy with maximum efficiency, and has low working efficiency.

[0005] The technical solution of the present invention is: a solar street lamp that greatly improves the efficiency of sunlight utilization, including a support rod, a repulsive force changing device, a deflection device, a limiting traction device, a light transmission device, a solar panel, a street lamp extension rod, a stabilizing rod and a lamp head, the top of the support rod is provided with a repulsive force changing device, the top of the repulsive force changing device is provided with a limiting traction device, the deflection device is arranged inside the repulsive force changing device and the limiting traction device, the light transmission device is arranged on the outer wall of the limiting traction device, and the top of the deflection device is provided with a solar panel.

[0006] Furthermore, the repulsive force changing device includes several wedge blocks arranged in a ring on the top of the support rod, a first magnet is provided on the opposite side of the adjacent wedge blocks, a heat conducting plate is provided on the outer wall of the first magnet, a plurality of heat conducting fins are provided on the outer wall of the heat conducting plate, and an annular plate is provided on the side of the heat conducting fin facing away from the heat conducting plate. The overall shape of the repulsive force changing device is a hollow frustum, with a deflection device at the center, and the deflection device is pulled by a limiting traction device.

[0007] Furthermore, the outer wall of the wedge block is provided with a mounting groove, and mounting blocks are provided on both sides of the heat conducting sheet, and the heat conducting sheet is engaged with the wedge block through the mounting blocks and the mounting groove. The clamping installation is convenient.

[0008] Furthermore, the inner wall of the wedge block is provided with a filling arc piece, and two sides of the filling arc piece are in contact with the adjacent first magnets.

[0009] When the deflection device deflects and moves due to the change in the magnetic field of the repulsive force changing device, the filling arc piece arranged on the inner wall of the wedge block can make the deflection process more consistent.

[0010] Furthermore, the deflection device includes a fixed round block and a plurality of supporting rods arranged in a circular array on the outer wall of the fixed round block, a second magnet is provided at one end of the supporting rod, the second magnet repels the first magnet, a support column is provided on the top of the fixed round block, the limiting traction device includes a hollow shell provided on the top of the wedge block and a first fixing ring provided on the inner wall of the hollow shell, the limiting traction device also includes a second fixing ring provided on the outer wall of the support column, a traction rope is provided between the first fixing ring and the second fixing ring, and a light-transmitting device is provided on the outer wall of the hollow shell.

[0011] The truncated cone design of the repulsion changing device, the limiting traction device and the light-transmitting device at the top of the support rod is more in line with the movement trajectory of the sun in a day, so that the repulsion changing device can always affect the deflection device and the solar panel on the top of the deflection device.

[0012] The limiting traction device performs traction and limiting on the deflection device, and adopts the cooperation of the first fixing ring, the second fixing ring and the traction rope to ensure that the deflection device can be changed at any time according to the magnetic change of the repulsive force changing device.

[0013] Furthermore, the hollow shell is truncated cone-shaped, and the deflection of the support column is limited by the top inner wall of the hollow shell. The truncated cone-shaped hollow shell has a small upper opening and a large lower opening, and the upper opening of the hollow shell limits the deflection of the support column to prevent the deflection angle from being too large.

[0014] Furthermore, the light-transmitting device includes a plurality of fixing plates fixed on the outer wall of the hollow shell in a circumferential array, the outer wall of the fixing plate is provided with a connecting block, one end of the connecting block is provided with a fixing ring, and a convex lens is provided inside the fixing ring.

[0015] The light-transmitting device concentrates sunlight heat onto the annular plate, raising its temperature and transferring the heat to the first magnet via the heat-conducting fins and plate. This reduces the magnetism of the first magnet on the side exposed to sunlight, while the first magnet on the other side, not directly exposed to sunlight, continues to function (repelling the second magnet on its side), thereby deflecting the solar panel on top of the support column toward the direction of direct sunlight. A limiting traction device ensures the deflection mechanism remains active.

[0016] In addition, when the position of the sun changes, the magnets whose magnetism has been reduced due to heat will recover their magnetism as the temperature gradually drops, ensuring that the deflection device can always change with the change of the sun's incident angle.

[0017] Furthermore, a street light extension rod is provided on the outer wall of the support rod near the top, the street light extension rod is supported by a stabilizing rod, and a lamp holder is provided at the end of the street light extension rod.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention cooperates with the repulsive force changing device and the light-transmitting device so that the deflection device fixed by the limiting traction device can change as the incident angle of sunlight changes; the light-transmitting device gathers the heat of sunlight on the annular sheet, and the annular sheet on the side whose temperature rises due to sunlight exposure transfers the heat to the first magnet through the heat-conducting fins and the heat-conducting sheet as a medium, so that the magnetism of the first magnet is reduced, while the first magnet not affected by the light-transmitting device still repels the second magnet, thereby causing the deflection device to deflect, so that the solar panel on the top of the deflection device can adapt to sunlight at different angles, thereby improving the solar panel's absorption efficiency of sunlight.

[0031] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 As shown, a solar street light that greatly improves the efficiency of sunlight utilization includes a support rod 1, a repulsive force changing device 2, a deflection device 3, a limiting traction device 4, a light transmission device 5, a solar panel 6, a street light extension rod 7, a stabilizing rod 8 and a lamp head 9, and is characterized in that: a repulsive force changing device 2 is provided on the top of the support rod 1, a limiting traction device 4 is provided on the top of the repulsive force changing device 2, the deflection device 3 is provided inside the repulsive force changing device 2 and the limiting traction device 4, the light transmission device 5 is provided on the outer wall of the limiting traction device 4, and a solar panel 6 is provided on the top of the deflection device 3.

[0032] The repulsive force changing device 2 includes several wedge blocks 201 arranged in a ring shape on the top of the support rod 1, and a first magnet 202 is provided on the opposite side of adjacent wedge blocks 201. The outer wall of the first magnet 202 is provided with a heat conducting plate 203, and the outer wall of the heat conducting plate 203 is provided with several heat conducting fins 204. The side of the heat conducting fin 204 facing away from the heat conducting plate 203 is provided with an annular plate 205. The overall shape of the repulsive force changing device 2 is a hollow frustum, with a deflection device 3 at the center, and the deflection device 3 is pulled by a limiting traction device 4.

[0033] The outer wall of the wedge block 201 is provided with a mounting groove, and mounting blocks are provided on both sides of the heat conducting sheet 203. The heat conducting sheet 203 is engaged with the wedge block 201 through the mounting blocks and the mounting groove.

[0034] The inner wall of the wedge block 201 is provided with a filling arc piece 206 , and both sides of the filling arc piece 206 are in contact with the adjacent first magnets 202 .

[0035] The repulsive force changing device will continuously affect the angular deflection of the deflection device based on the principle that the magnetism of a magnet decreases when it is heated, thereby adapting to sunlight at different angles and maximizing the efficiency of the solar panels on top of the deflection device in absorbing sunlight.

[0036] The mounting block and mounting groove are engaged with the wedge block for easy installation. In addition, when the deflection device is deflected and moved due to the change in the magnetic field of the repulsive force changing device, the filler arc piece provided on the inner wall of the wedge block can make the deflection process more consistent.

[0037] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, the deflection device 3 includes a fixed circular block 301 and a plurality of supporting rods 302 arranged in a circular array on the outer wall of the fixed circular block 301, a second magnet 303 is provided at one end of the supporting rod 302, and the second magnet 303 repels the first magnet 202. A support column 304 is provided on the top of the fixed circular block 301, and the limiting traction device 4 includes a hollow shell 401 provided on the top of the wedge block 201 and a first fixing ring 402 provided on the inner wall of the hollow shell 401. The limiting traction device 4 also includes a second fixing ring 403 provided on the outer wall of the support column 304, a traction rope 404 is provided between the first fixing ring 402 and the second fixing ring 403, and a light-transmitting device 5 is provided on the outer wall of the hollow shell 401.

[0038] The light transmitting device 5 includes a plurality of fixing plates 501 fixed to the outer wall of the hollow shell 401 in a circumferential array. The outer wall of the fixing plate 501 is provided with a connecting block 502. One end of the connecting block 502 is provided with a fixing ring 503. A convex lens 504 is provided inside the fixing ring 503.

[0039] The hollow shell 401 is truncated, and the deflection of the support column 304 is limited by the top inner wall of the hollow shell 401. A street light extension rod 7 is provided on the outer wall of the support rod 1 near the top, and the street light extension rod 7 is supported by a stabilizing rod 8. The end of the street light extension rod 7 is provided with a lamp holder 9.

[0040] When sunlight shines on the solar street light in a certain direction, the light-transmitting device will concentrate the heat of the sunlight on the annular sheet, thereby increasing the temperature of the annular sheet facing the sunlight. The heat is then transferred to the first magnet through the heat-conducting fins and the heat-conducting sheet, thereby reducing its magnetism (the first magnet and the second magnet are arranged to repel each other, and the magnetic force of the magnets decreases due to the increase in temperature, and the repulsive force of the first magnet on the second magnet decreases). The first magnet that is not affected by the light-transmitting device (on the back side facing direct sunlight) still repels the second magnet, thereby causing the deflection device to deflect, so that the solar panel on the top of the deflection device can adapt to sunlight at different angles.

[0041] As the sun's position changes, the magnets, whose magnetism has been reduced by heat, gradually regain their magnetism as the temperature drops, ensuring that the deflection device can consistently adjust to the changing angle of the sun's incidence. The combination of thermal fins and a heat conducting sheet evenly distributes heat across the first magnet, preventing damage to the magnet from excessive heat.

[0042] Furthermore, a limited traction device limits the deflection mechanism's position. The first and second fixed rings, along with a traction rope, ensure the deflection mechanism can be adjusted at any time based on the magnetic field of the repulsive force altering device. The truncated cone-shaped hollow shell, with a narrow top opening and a wide bottom opening, limits the deflection of the support column, preventing excessive deflection.

[0043] The above are merely specific application examples of the present invention and do not constitute any limitation on the scope of protection of the present invention. In addition to the above embodiments, the present invention may also have other implementations. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection claimed by the present invention.
