[0002] Mobile lighthouses are widely applicable to large-area lighting in places such as wide roads, overpasses, squares, docks, tank farms, warehousing, ports, freight yards, train marshalling yards, airport aprons, etc.

[0003] With the popularization of photovoltaics, more and more mobile lighthouses are equipped with solar panels to provide electrical energy for the power supply of the mobile lighthouses. However, currently, the solar panels on common mobile lighthouses in the market are of a fixed draw type, that is: the solar panels are fixedly installed on the mobile lighthouse, and the solar panels can be unfolded from both sides. This fixed draw type structure is not convenient for adjusting the angle of the solar panels, thereby making the solar panels maintain a better light-receiving angle, thus reducing the power generation efficiency; moreover, when this fixed draw type structure is unfolded, there are only three solar panels, and the power generation ability is not strong. Therefore, it is necessary to improve the above technical problems, and this case is thus born. Summary of the Utility Model

The hinge column is used for hinging with the mobile lighthouse body. One side of the solar panel frame is provided with a connecting ear, and the connecting ear is provided with a connecting through hole for the vertical column to penetrate through. A bearing sleeved on the outside of the vertical column is installed in the connecting through hole.

[0010] Further, the connecting ears between adjacent two solar panels are separated by a positioning ring sleeved on the outside of the vertical column. The upper end of the vertical column is sleeved with a fastening ring, and the outside of the lower end of the vertical column is sleeved with a positioning sleeve. The lower end of the positioning sleeve is provided with an upper fixed flange. The upper end of the hinge column is provided with a lower fixed flange, and the upper fixed flange and the lower fixed flange are locked and fixed through bolts.

[0024] The following further describes the present utility model in detail with reference to the drawings and specific implementation manners.

[0025] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0026] As Figures 1 to 10 shown, a structure of an adjustable-angle rotary solar panel of the present utility model includes a swing shaft 2 and a mobile lighthouse body 1. One end of the swing shaft 2 is hinged to the front end of the mobile lighthouse body 1 and can swing up and down. Four evenly spaced solar panels 3 are rotatably installed on the swing shaft 2 along the axial direction. The four solar panels 3 can rotate coaxially around the swing shaft 2 to unfold and fold. Each solar panel 3 adopts an existing draw-out structure. By arranging four solar panels that can rotate coaxially to unfold and fold on a swing shaft that can swing up and down, it is convenient to adjust the angle of the solar panels so that the solar panels can maintain a better light-receiving angle; and each solar panel adopts a draw-out structure, which can effectively increase the solar energy collection area.

[0027] In this embodiment, the structures of each solar panel 3 are the same and each includes a rectangular frame-shaped solar panel frame 4. The solar panel frame 4 is rotatably connected to the swing shaft 2. A solar main board 5 is fixedly arranged on the solar panel frame 4, and a solar sub-board 6 that can be pulled out toward the periphery of the solar panel frame 4 is arranged at the bottom of the solar panel frame 4. During use, the solar panel frame is rotated around the swing shaft, and the solar panel frame drives the solar main board to rotate; when the solar sub-board is needed to be used, the solar sub-board is pulled out so that the solar sub-board and the solar main board are arranged side by side, increasing the solar cell area and improving the overall power generation efficiency of the system. Since there are four solar panels, and each solar panel includes a solar sub-board and a solar main board, when the four solar panels are rotated and unfolded and pulled out, there are a total of eight sheets.

[0028] In this embodiment, when multiple solar panels are unfolded around the swing shaft, the pulling directions of the solar sub-boards 6 of adjacent two solar panels 3 are opposite, that is, they are pulled out and unfolded toward the left and right sides.

[0029] In this embodiment, a pair of oppositely distributed slide rails 7 are arranged at the bottom of the solar panel frame 4, and the two ends of the solar sub-board 6 are slidably matched with the pair of slide rails 7 to facilitate the pulling of the solar sub-board.

[0030] In this embodiment, the swing shaft 2 includes a column 8 and a hinge column 9 that are coaxially arranged and distributed up and down. The hinge column 9 is used for hinging with the mobile lighthouse body 1; a connecting ear 10 is arranged on one side of the solar panel frame 4, and the connecting ear 10 is provided with a connecting through hole for the column 8 to pass through. A bearing 11 sleeved on the outside of the column 8 is installed in the connecting through hole. By means of the bearing, the connecting ear and the column are rotationally matched, and further, the solar panel and the swing shaft are rotationally connected. Rotating by using the bearing has the characteristics of simple structure, low manufacturing cost, long service life, good stability, and easy maintenance.

[0031] In this embodiment, the connecting ears 10 of adjacent two solar panels 3 are separated by a positioning ring 12 sleeved on the outside of the column 8. A fastening ring 13 is sleeved on the upper end of the column 8, and the fastening ring 13 is used for limiting the uppermost bearing. Preferably, the fastening ring can be a clamp. Further, a positioning sleeve 14 is sleeved on the outside of the lower end of the column 8, and a positioning ring 12 is also arranged between the positioning sleeve 14 and the lowermost bearing. An upper fixed flange 15 is arranged at the lower end of the positioning sleeve 14; a lower fixed flange 16 is arranged at the upper end of the hinge column 9, and the upper fixed flange 15 and the lower fixed flange 16 are locked and fixed by bolts 17, thereby realizing the connection and fixation of the column and the hinge column.

[0032] In this embodiment, a hinge sleeve 18 is fixed to the lower end of the hinge column 9, and the axis of the hinge sleeve 18 is perpendicular to the axis of the hinge column 9; a notch 19 for facilitating the insertion of the hinge column is provided at the front end of the mobile lighthouse body 1, and a hinge rotating shaft 20 passing through the hinge sleeve 18 is provided in the notch 19, and a hinge structure is formed by the hinge sleeve and the hinge rotating shaft.

[0033] In this embodiment, the up-and-down swing of the swing rotating shaft 2 can be adjusted manually or by means of a motor.

[0034] Implementation process:

[0035] (1) Adjust the posture of the column: When the column is in the horizontal initial state, the primary step is to place it vertically through rotation or adjust it to the optimal receiving position according to the incident angle of sunlight to ensure the maximum utilization of light energy;

[0036] (2) Rotate and unfold the solar panels: According to the logical order from top to bottom, rotate each solar main panel to its preset limit angle one by one. For example, the four solar panels from top to bottom are the first solar panel 21, the second solar panel 22, the third solar panel 23, and the fourth solar panel 24. The first solar panel rotates counterclockwise by 90 degrees, the second solar panel rotates counterclockwise by 180 degrees, the third solar panel rotates counterclockwise by 270 degrees, and the fourth solar panel rotates counterclockwise by 360 degrees. At this time, the four solar panels are rotated and unfolded, with two solar panels on the left and two solar panels on the right, ensuring that each solar main panel can capture solar radiation to the maximum extent;

[0037] (3) Deploy the solar sub-panels: By smoothly pulling the solar sub-panels of each solar panel to the left and right sides, the solar sub-panels are fully pulled out and unfolded to increase the solar collection area.

[0038] The advantages of the present utility model are as follows:

[0039] (1) High solar energy utilization rate: The angle of the solar panels can be manually adjusted according to the position of the sun, which is convenient for the solar panels to face the sun better, so as to maximize the reception of solar radiation energy; In contrast, without moving the lighthouse, the fixed solar panels can only receive solar energy in a fixed direction and cannot adjust the angle according to the movement of the sun. Therefore, in different time periods and seasons, the amount of solar radiation received by them will be greatly affected;

[0040] (2) Improve the power generation efficiency: Since the solar panels can be adjusted to always face the sun, the solar panels can convert solar energy into electrical energy more effectively, thereby improving the power generation efficiency of the entire solar energy system;

[0041] (3) Stronger power generation capacity: The rotating structure combined with the pulling and pushing structure can deploy more solar panels, thus achieving stronger power generation capacity.

[0042] (4) Easy to maintain and clean: Since the solar panels can be rotated and retracted, they can be retracted for maintenance, which is more convenient during maintenance; when cleaning or replacing the solar panels is required, they can be easily rotated to a convenient operation position, reducing the difficulty and cost of maintenance.

[0043] (5) High space utilization rate: In some special cases, such as in an environment with limited space, the solar panels can be rotated and retracted to optimize space utilization; when not in use, they can be retracted to reduce space occupation.

[0044] If the present utility model discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (such as using bolts or screws for connection), or it can also be understood as: a non-detachable fixed connection (such as riveting, welding). Of course, the mutually fixed connection can also be replaced by an integral structure (such as manufactured by an integral casting process) (except where it is clearly impossible to adopt the integral forming process).

[0045] In addition, for any technical solution disclosed in the present utility model above, the terms used to represent the positional relationship or shape, unless otherwise stated, include states or shapes that are approximate, similar, or close to it.

[0046] Any component provided by the present utility model can either be assembled from multiple separate components or be a single component manufactured by an integral forming process.

[0047] Finally, it should be noted that: The above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them; although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: It is still possible to modify the specific implementation manners of the present utility model or perform equivalent replacements for some technical features; without departing from the spirit of the technical solutions of the present utility model, they should all be covered within the scope of the technical solutions claimed by the present utility model.
