Description

Technical Field

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

[0002] Solar streetlights are popular because they generate electricity by installing solar panels on light poles, saving on electricity bills. More and more roads are installing solar streetlights to replace traditional grid-connected streetlights.

[0003] To better receive sunlight, the solar panels are tilted upwards, making it easy for dust to accumulate on this surface. Over time, this dust can severely block the light. Additionally, bird droppings can also fall on the solar panels, further obstructing the light. When the solar panels are blocked from receiving sunlight, their power generation efficiency decreases, affecting the normal operation of the solar streetlights. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned problems existing in the prior art and to provide a solar panel for a solar street light.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0006] A solar panel for a solar street light includes a rectangular solar cell module. A guide rail is installed on each of the left and right sides of the solar cell module. A brush mechanism for cleaning the upper surface of the solar cell module is installed between the two guide rails. A traction mechanism for pulling the brush mechanism to move back and forth along the two guide rails is also installed between the two guide rails. A mounting bracket for supporting the solar panel on the top of the solar street light is installed in the middle of the two guide rails.

[0007] The guide rail has an "E" shaped cross-section, and its inner side is provided with a component mounting groove and a sliding groove, with the component mounting groove and the sliding groove being parallel to each other.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] like Figures 1 to 9 As shown, a solar panel for a solar street light includes a rectangular solar cell module 1. A guide rail 2 is installed on the left and right sides of the solar cell module 1. The cross-section of the guide rail 2 is "E" shaped. A module mounting groove 21 and a sliding groove 22 are provided on the inner side of the guide rail 2. The module mounting groove 21 and the sliding groove 22 are parallel to each other. The side of the solar cell module 1 is installed in the module mounting groove 21.

[0029] A brush mechanism 3 for cleaning the upper surface of the solar cell module is installed between the two guide rails 2. The brush mechanism 3 includes a motor mounting base 31, a bearing mounting base 32, a tubular motor 33, and a brush cylinder 34 with one end closed. The outer bottom of the motor mounting base 31 and the outer bottom of the bearing mounting base 32 are respectively provided with outwardly protruding sliders 35, which slide in conjunction with the slide groove 22. The fixed head of the tubular motor 33 is installed in the motor mounting base 31, and the power output shaft of the tubular motor 33 is inserted into the socket hole 341 inside the brush cylinder 34. The tubular motor 33 is sleeved in the brush cylinder 34. An outwardly protruding mounting shaft 342 is provided at the center of the outer side of the closed end of the brush cylinder 34. A bearing 36 is installed in the bearing mounting base 32, and the mounting shaft 342 is sleeved in the inner ring of the bearing 36.

[0030] The outer surface of the brush cylinder 34 is provided with at least one spiral brush filament strip 343. The brush filament strip 343 is composed of several bundles of brush filaments arranged in a spiral shape. The distance between the end of the brush filament bundle and the central axis of the brush cylinder 34 is 2mm larger than the distance between the upper surface of the solar cell module 1 and the central axis of the brush cylinder 34. The brush filament bundle is processed by first drilling several circular holes arranged in a spiral shape on the outer surface of the brush cylinder 34, and then clamping the middle part of the brush filament bundle with steel wire to insert the brush filament bundle into the circular holes in a folded state.

[0031] The tubular motor 33 drives the brush cylinder 34 and the brush bristles 343 to rotate, thereby cleaning the upper surface of the solar cell module by the brush bristles 343, removing dust and bird droppings from the upper surface of the solar cell module, and preventing the power generation efficiency of the solar cell module from being reduced due to dust and bird droppings.

[0032] The brush mechanism 3 also includes a U-shaped protective cover 37. The two ends of the protective cover 37 are screwed onto the motor mounting base 31 and the bearing mounting base 32, respectively. The side of the brush cylinder 34 furthest from the solar cell module 1 is covered by the protective cover 37. The protective cover 37 protects the brush cylinder 34 and the brush bristles 343, preventing them from aging due to prolonged exposure to wind and sun, thus extending their service life.

[0033] A self-lubricating bushing 38 is installed between the brush cylinder 34 and the tubular motor 33. The self-lubricating bushing 38 supports the brush cylinder and prevents the brush cylinder 34 from shaking.

[0034] A traction brush mechanism 3 is also installed between the two guide rails 2, and a traction mechanism 4 moves back and forth along the two guide rails 2. The traction mechanism 4 includes a motor frame 41 and two bead chains 42. The two ends of the motor frame 41 are connected to the guide rails 2 with screws. A stepper motor 43 is installed in the middle of the motor frame 41. A drive gear 44 is installed on the power output shaft of the stepper motor 43. A seated bearing 45 is installed at each end of each guide rail 2. A rotating shaft 46 is installed between the two seated bearings 45 at the same end of the guide rail 2. A driven gear 47 that meshes with the drive gear 44 is installed in the middle of one of the rotating shafts 46. A roller 48 is installed at each end of each rotating shaft 46. A bead chain engagement groove 481 is provided on the outer side of the roller 48. The bead chain 42 engages with the bead chain engagement groove 481. The two ends of one bead chain 42 are connected to the motor mounting base 31, and the two ends of the other bead chain 42 are connected to the bearing mounting base 32.

[0035] The stepper motor 43 drives the drive gear to rotate, which in turn causes the roller 48 to rotate through the driven gear and the shaft. This, in turn, causes the ball chain to rotate, which in turn drives the motor mounting base 31 and the bearing mounting base 32 to move back and forth along the slide groove 22 of the guide rail 2.

[0036] A motor controller is installed in the lamp post of the solar street light to control the operation of the stepper motor 43 and the tubular motor 33.

[0037] A mounting bracket 5 is installed in the middle of the two guide rails 2 to support the solar panel on top of the solar street light. Specifically, the mounting bracket 5 includes a rectangular support plate 51 and a circular mounting cylinder 52. The mounting cylinder 52 is vertically welded to the bottom center of the support plate 51. A right-angled trapezoidal side plate 53 is welded to the left and right sides of the support plate 51, and the side plates 53 are perpendicular to the support plate 51. The guide rails 2 are screwed to the inside of the side plates 53. Multiple connecting rods 54 are welded between the two side plates 53.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
