Most warning signs on the market only provide simple warning functions, which are not effective at night or when visibility is poor. The warning function is significantly weakened, which is not conducive to the safety of power construction.

DETAILED DESCRIPTION

[0033] The specific implementation modes of the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] The smart power warning sign under this specific implementation mode is as follows: Figure 1 and Figure 2As shown, it includes a supporting base plate 1, moving wheels 2, a warning sign assembly 3 and a solar panel assembly 4. Four moving wheels 2 with rectangular structures are fixedly connected to the bottom of the supporting base plate 1. The moving wheels 2 can be used to facilitate the movement of the warning sign to the designated area of ​​the power equipment for use, making the movement of the warning sign more labor-saving and convenient. The warning sign assembly 3 is arranged above the supporting base plate 1. A solar panel assembly 4 is arranged above the warning sign assembly 3. The solar panel assembly 4 is connected to the adjustment mechanism through the support frame assembly 5. The adjustment mechanism includes an installation shell 6, a fixed shell 7 and a support shell 37. One side of the installation shell 6 is fixed A receiving discharge motor 8 is provided, and the output end of the receiving discharge motor 8 is fixedly connected to a driving shaft 9, a translation structure is connected to the surface of the driving shaft 9, a driving gear 10 is fixedly connected to one end of the driving shaft 9, a driven gear 11 is meshingly connected to the side of the driving gear 10, the driven gear 11 is fixedly connected to the surface of a driven shaft 12, an adjustment line 13 is fixedly connected to the surface of the driven shaft 12, an end of the adjustment line 13 away from the driven shaft 12 is connected to the bottom of the solar panel assembly 4 through a guide shaft 14, a fixed shell 7 is arranged below the mounting shell 6, a support shell 37 is arranged below the fixed shell 7, and the fixed shell 7 and the support shell 37 are connected by a vertical rotation structure.

[0035] When the warning sign is in use, the retractable discharge motor 8 is used to drive the driving shaft 9 to rotate, thereby driving the driving gear 10 to rotate, and then driving the driven gear 11 to rotate. At this time, the driven shaft 12 can be driven to rotate. The rotation directions of the two driven shafts 12 are opposite, so that when the two driven shafts 12 rotate, the adjustment line 13 on one side can be reeled in, and the adjustment line 13 on the other side can be loosened. At this time, under the action of the support frame assembly 5, the solar power generation panel assembly 4 can rotate with the retraction and release of the adjustment lines 13 on both sides, so as to adjust the inclination angle of the solar power generation panel assembly 4, and when the retractable discharge motor 8 drives the driving shaft 9 to rotate, it can drive the translation structure connection, so as to adjust the horizontal angle of the solar power generation panel assembly 4, so that the solar power generation panel assembly 4 can move following the movement of the sun, so that the sunlight can always shine on the solar power generation panel assembly 4, which is convenient for the solar power generation panel assembly 4 to generate electricity.

[0036] It should be noted that the retraction and extension of the adjustment line 13 is controlled by the retractable discharge motor 8, and the degree of retraction and extension can be determined by calibration. According to the calibration result, the retractable discharge motor 8 controls the retraction and extension of the adjustment line 13, thereby ensuring that at different times, the solar panel assembly 4 can automatically follow the sun, thereby achieving an intelligent sun-chasing effect.

[0037] Through the above technical solution, the solar panel assembly 4 is driven to rotate by the retractable adjustment line 13, so that the solar panel assembly 4 can adjust the tilt angle according to the sun's irradiation angle, and the rotation of the first bevel gear 15 and the second bevel gear 16 can drive the solar panel assembly 4 to rotate, so that the solar panel assembly 4 can adjust the horizontal angle according to the position of the sun, so that the sunlight can always irradiate the solar panel assembly 4, that is, the solar panel assembly 4 can adjust the horizontal angle and tilt angle according to the position of the sun, so that the sunlight can always irradiate the solar panel assembly 4 at the best angle, and the driving source of the adjustment line 13 and the first bevel gear 15 is the same. The energy consumption of the warning sign is reduced and energy is saved. The dual-axis motor 20 can be used to drive the mounting shell 6 to rotate, and the solar panel assembly 4 can be rotated downward in severe weather such as rain, snow, and hail. At this time, the mounting shell 6 can protect the solar panel assembly 4 to prevent the solar panel assembly 4 from being damaged by hail, etc., thereby reducing the damage rate of the solar panel assembly 4, increasing the service life of the solar panel assembly 4, and expanding the use scenarios of the warning sign. The warning motor 29 can be used to drive the warning sign assembly 3 to rotate, and the warning angle can be adjusted, and the angle of the warning sign assembly 3 can be adjusted arbitrarily, so that the angle adjustment of the warning sign assembly 3 is more precise, and the use of the warning sign is more flexible.

[0039] When the retractable electric motor 8 drives the driving shaft 9 to rotate, the driving shaft 9 also drives the first bevel gear 15 to rotate, thereby driving the second bevel gear 16 to rotate. When the second bevel gear 16 rotates, it can drive the rotating shaft 17 to rotate, thereby driving the rotating plate 18 to rotate, and then driving the connecting column 19 to rotate. At this time, the mounting shell 6 and the solar power generation panel assembly 4 and other structures can be driven to rotate, and the horizontal angle of the solar power generation panel assembly 4 can be adjusted, so that the solar power generation panel assembly 4 can adjust the horizontal angle when adjusting the tilt angle, so that the solar power generation panel assembly 4 can be adjusted with the movement of the sun during the day, so that the solar power generation panel assembly 4 can always be illuminated by sunlight, thereby improving the power generation capacity of the solar power generation panel assembly 4, facilitating the power supply for the warning sign, so that the warning sign does not need an external power supply when in use, and increases the flexibility of the warning sign when in use.

The end of the support column 28 away from the upper gear 27 is fixed to the side of the fixed shell 7.

[0041] When encountering severe weather such as rain, snow, and hail, the dual-axis motor 20 is used to drive the transmission shaft 21 to rotate, thereby driving the first sprocket 22 to rotate, and then driving the transmission sprocket 23 to rotate. When the transmission sprocket 23 rotates, it can drive the second sprocket 24 to rotate, thereby driving the lower gear 26 to rotate, and at this time, it can drive the upper gear 27 and the support column 28 to rotate, thereby driving the fixed shell 7 and the solar power generation panel assembly 4 and other structures to rotate, and flip the solar power generation panel assembly 4 so that the solar power generation panel assembly 4 is under the fixed shell 7. At this time, the fixed shell 7 can block rain, snow, hail, etc., thereby protecting the solar power generation panel assembly 4 and improving the service life of the solar power generation panel assembly 4, thereby reducing the maintenance rate and damage rate of the warning sign, and reducing the use cost of the warning sign.
