[0031] In an optional embodiment of the present invention, two or more balls 29 are rotatably connected to the fourth wedge-shaped block 28 to reduce the movement friction and make the fourth wedge-shaped block 28 easier to move up and down.

[0034] In an optional embodiment of the present invention, the first wedge block 24 is located between the second wedge block 26 and the third wedge block 27, and the second wedge block 26 and the third wedge block 27 are respectively abutted against the first wedge block 24.

[0035] In an optional embodiment of the present invention, both the connecting rod 15 and the baffle 16 are located outside the chassis 1, and the baffle 16 is located above the chassis 1.

[0036] In an optional embodiment of the present invention, the air deflector 21 is made of polyethylene. The air deflector 21 made of polyethylene material is light and durable, improving the air guiding performance.

[0037] In an optional embodiment of the present invention, the chassis 1 is provided with heat dissipation holes communicating with the photovoltaic panel assembly 2 for discharging heat, preventing the temperature inside the chassis 1 from being too high, and ensuring the normal operation of the device.

[0038] In an optional embodiment of the present invention, the photovoltaic panel assembly 2 is movably connected to the top wall of the chassis 1 through an angle adjustment device 3, and the orientation of the photovoltaic panel assembly 2 can be adjusted according to the sunlight angle, thereby improving the solar energy absorption efficiency and power generation performance.

[0039] Implementation process:

[0040] Install this device on the intelligent bus stop. The photovoltaic panel assembly 2 receives solar energy and converts the solar energy into electrical energy, which is stored in the energy storage body 4. The energy storage body 4 supplies power to the intelligent bus stop.

[0041] When the energy storage body 4 and other electrical components in the chassis 1 work, heat will be generated. Start the motor 6 to make the first gear 8 and the wind blade 9 rotate. The wind blade 9 sends the heat in the cavity 5 to the outside of the chassis 1 through the heat dissipation holes, thereby protecting all electrical components from heat damage.

[0042] The self - resetting rotating shaft 17 realizes self - resetting by using an elastic component. The elastic component is, for example, a torsion spring, which is not limited here. The elastic force of the elastic component prevents the gentle breeze from blowing the air deflector 21 to rotate the self - resetting rotating shaft 17. When a strong wind blows onto the air deflector 21, the air deflector 21 drives the self - resetting rotating shaft 17 to rotate a certain angle in one direction. The gear four 22 on the self - resetting rotating shaft 17 drives the rack 23 and the wedge - shaped block one 24 to move left or right, so that the wedge - shaped block one 24 pushes the wedge - shaped block two 26 or the wedge - shaped block three 27 to move downwards, thereby causing the displacement plate 25 and the wedge - shaped block four 28 to move downwards. The wedge - shaped block four 28 extends into the receiving groove 20, and one of the push pieces 18 on the self - resetting rotating shaft 17 rotates to push the transfer plate 11 to move rightwards. The gear three 12 meshes with the gear one 8 and the gear two 10. The gear one 8 drives the gear three 12 and the gear two 10 to rotate. The gear two 10 drives the toothed plate 14 to move rightwards, so that the baffle 16 moves above the photovoltaic panel assembly 2 to protect the photovoltaic panel assembly 2 and prevent other sundries blown by the strong wind from hitting the photovoltaic panel assembly 2. After the toothed plate 14 disengages from the gear two 10, the toothed plate 14 will continue to move rightwards for a certain distance under the action of inertia. During the entire right - ward movement of the toothed plate 14, the automatic wire winder 39 releases the transmission wire 38. When the inclined surface of the wedge - shaped block four 28 abuts against the receiving groove 20 and moves upwards, when the limiting groove 19 moves below the wedge - shaped block four 28, the wedge - shaped block four 28 moves downwards under the elastic force of the spring member 37 and extends into the limiting groove 19 to temporarily prevent the toothed plate 14 from moving leftwards to reset. The permanent magnet strip 30 moves below the permanent magnet block two 36, and the magnetic repulsive force of the permanent magnet block two 36 causes the permanent magnet strip 30 to move downwards until the limiting piece 31 abuts against the top wall of the limiting block two 33, and the permanent magnet strip 30 moves downwards to the right of the extension block 13.

[0043] When the strong wind stops, the air deflector 21 loses the push of the wind force. The self - resetting force of the self - resetting rotating shaft 17 causes the self - resetting rotating shaft 17 to reset. The push piece 18 disengages from the abutment with the transfer plate 11. The gear three 12 disengages from the gear one 8 and the gear two 10. The gear four 22 drives the rack 23 and the wedge - shaped block one 24 to reset. The displacement plate 25 moves upwards to reset under the elastic force of the spring member 37. The wedge - shaped block four 28 disengages from the limiting groove 19. After the toothed plate 14 loses the limitation of the wedge - shaped block four 28, the automatic recovery force of the automatic wire winder 39 recovers the transmission wire 38. The transmission wire 38 pulls the toothed plate 14 to move leftwards to reset. The baffle 16 releases the protection of the photovoltaic panel assembly 2. The photovoltaic panel assembly 2 continues to absorb solar energy for power generation. The permanent magnet strip 30 pushes the extension block 13 to move leftwards, so that the transfer plate 11 moves leftwards to reset. After the gear three 12 disengages from the gear two 10 and the gear one 8, the toothed plate 14 re - engages with the gear two 10. When the permanent magnet strip 30 moves below the permanent magnet block one 35, the permanent magnet strip 30 moves upwards under the magnetic suction force of the permanent magnet block one 35 until the limiting piece 31 abuts against the bottom wall of the limiting block one 32, and the extension block 13 and the transfer plate 11 stop moving leftwards, completing the reset, so as to facilitate the protection of the photovoltaic panel assembly 2 again using the above principle when the air deflector 21 is affected by strong wind next time.

[0044] The heat dissipation can be achieved by driving the wind blade 9 with the motor 6 of the present invention, protecting the electrical components from heat damage; when strong wind blows, the self-resetting rotating shaft 17 can be rotated by the guiding wind plate 21. No matter which direction the self-resetting rotating shaft 17 rotates, that is, from which direction the wind blows, the baffle 16 can be moved to the right to protect the photovoltaic panel assembly 2, preventing sundries from falling onto the photovoltaic panel assembly 2, thus effectively protecting the photovoltaic panel assembly 2. After the strong wind stops, due to the self-resetting force of the self-resetting rotating shaft 17, the baffle 16 automatically moves to the left to reset, releasing the protection of the photovoltaic panel assembly 2, so that the photovoltaic panel assembly 2 can continue the energy conversion work, and can automatically reset the components in the box cavity 5, so as to continue to protect the photovoltaic panel assembly 2 when the strong wind blows next time. The present invention only needs to rely on the wind force and the force required to drive the wind blade 9 to complete the protection of the photovoltaic panel assembly 2, without setting additional electric drive, with high linkage and energy saving.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
