[0048] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0049] like Figure 1-Figure 12 As shown, a solar luminous warning sign, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 , comprising a pole 1, a LED luminous warning sign 2 for displaying warning information is fixedly installed on the front of the pole 1 near the upper end, a solar energy storage mechanism 3 for absorbing light energy is installed on the top of the pole 1, a cleaning and protection mechanism 4 for protecting and cleaning the solar energy storage mechanism 3 is arranged outside the pole 1, a control cabinet 6 is fixedly installed on the front of the pole 1 near the lower end, a wind-resistant mechanism 7 for improving the wind-resistant performance of the solar luminous warning sign is fixedly installed at the bottom of the pole 1, and a fixing mechanism 8 for installing the solar luminous warning sign is arranged at the bottom of the wind-resistant mechanism 7;

[0050] The cleaning and protection mechanism 4 includes two parallel protection plates 401, a velvet cleaning plate 403 is fixedly installed on the back of the protection plate 401, a telescopic rod 405 is arranged behind the protection plate 401, and the bottom end of the telescopic rod 405 is fixedly connected to the protection plate 401 by bolts, a gear 406 is fixedly installed on one side of the telescopic rod 405 near the top, and the gears 406 on the two telescopic rods 405 are meshed and connected with each other, a coupling 407 is fixedly installed at the top at the front and rear ends of one of the telescopic rods 405, and a servo motor 408 is installed at the top at the front and rear ends of the other telescopic rod 405, and the output shaft of the servo motor 408 is fixedly connected to the telescopic rod 405.

[0051] Specifically, the solar luminous warning sign is installed at an appropriate position of the electric angle steel tower through the fixing mechanism 8, and the light intensity parameter is set through the control cabinet 6. When the value of the ambient light intensity parameter is less than the set light intensity parameter, the two protective plates 401 in the cleaning protection mechanism 4 are in a closed state to protect the solar energy storage mechanism 3. When the value of the ambient light intensity parameter is greater than or equal to the set light intensity parameter, the servo motor 408 starts to drive one of the telescopic rods 405 to rotate, and the gear 406 drives the other telescopic rod 405 to rotate. The rotation of the two telescopic rods 405 drives the two protective plates 401 to unfold, exposing the solar energy storage mechanism 3 to absorb light energy and convert it into electrical energy, and in the process of unfolding the protective plates 401 During the process, the surface of the solar energy storage mechanism 3 is cleaned by the velvet cleaning plate 403, and foreign matter attached to the surface of the solar energy storage mechanism 3 is wiped clean to prevent foreign matter from accumulating on the surface of the solar energy storage mechanism 3, covering the light absorption area, and reducing the efficiency of light energy conversion. In the process of using the solar energy luminous warning sign, the electric energy converted by the solar energy storage mechanism 3 is used to power the LED luminous warning sign 2, and the warning information is displayed by the LED luminous warning sign 2. When the environmental wind is strong, the wind blows onto the solar energy luminous warning sign, and the wind-resistant mechanism 7 is used to drive the vertical pole 1 to rotate, and then drive the various components connected to the vertical pole 1 to rotate, thereby reducing the impact of wind on the solar energy luminous warning sign and improving the wind-resistant performance of the solar energy luminous warning sign.

[0052] Please refer to Figure 6 , Figure 7 and Figure 8 The cleaning and protection mechanism 4 also includes an electric heating wire 402 fixedly installed between the protection plate 401 and the velvet cleaning plate 403, and the velvet cleaning plate 403 is composed of a heat conducting plate and a velvet cleaning cloth. The inner walls of the top and bottom ends of the protection plate 401 are fixedly installed with limiting protrusions 404 on one side, and a plurality of leakage holes 409 are opened through the bottom of the protection plate 401.

[0053] Specifically, when the heating wire 402 is started, the velvet cleaning plate 403 is heated to evaporate the moisture on the velvet cleaning plate 403, so as to ensure the dryness of the velvet cleaning plate 403. When moisture appears on the surface of the solar energy storage mechanism 3, the dry velvet cleaning plate 403 absorbs the moisture, thereby ensuring the dryness of the solar energy storage mechanism 3 and extending the service life of the solar energy storage mechanism 3.

[0054] Please refer to Figure 1 and Figure 3 The solar energy storage mechanism 3 includes a solar panel 301, and a battery, a control panel and a control circuit are installed inside the control cabinet 6.

[0055] Specifically, after absorbing light energy, the solar panel 301 converts the light energy into electrical energy and stores it in a battery, so as to power the LED luminous warning sign 2 .

[0056] Please refer to Figure 1 , Figure 5 and Figure 6 The solar energy storage mechanism 3 also includes a plurality of patch type humidity sensors 303 fixedly mounted on both sides of the solar panel 301 frame, wherein a same scraper 304 is fixedly mounted on one side of the plurality of patch type humidity sensors 303 located on the same side, and limiting grooves 302 are provided at the top and bottom ends of the solar panel 301 frame, and the protective plate 401 is slidably connected to the frame of the solar panel 301 through the limiting protrusion 404 and the limiting groove 302, and the velvet cleaning plate 403 is fitted with the surface of the solar panel 301, and the housing of the servo motor 408 is fixedly connected to the frame of the solar panel 301, and the coupling 407 is movably connected to the frame of the solar panel 301 through a bearing, and the patch type humidity sensor 303 is one of a capacitive humidity sensor and a resistive humidity sensor.

[0057] Specifically, during the unfolding of the protective plate 401, the surface of the velvet cleaning plate 403 is cleaned by the scraper 304, and foreign matter attached to the surface of the velvet cleaning plate 403 is scraped off and leaked out through the leak hole 409, so as to facilitate the removal of foreign matter attached to the surface of the velvet cleaning plate 403, and avoid a large number of foreign matter attached to the surface of the velvet cleaning plate 403, which makes it difficult to clean the solar panel 301. During the unfolding of the protective plate 401, the chip-type humidity sensor 303 contacts the velvet cleaning plate 403 to detect the humidity of the velvet cleaning plate 403. When the detected humidity parameter is greater than or equal to the set fixed humidity parameter, the heating wire 402 is started to heat and dry the velvet cleaning plate 403 to evaporate the moisture on the velvet cleaning plate 403, so as to ensure the dryness of the velvet cleaning plate 403.

[0058] Please refer to Figure 1 and Figure 2 A canopy 9 is fixedly installed on the top of the LED luminous warning sign 2, and the top of the canopy 9 is arranged in an arc surface.

[0059] Specifically, when the foreign matter scraped off by the scraper 304 leaks out through the leakage hole 409, it falls on the top of the awning 9 and rolls down to both sides along the top surface of the awning 9, leaving the solar luminous warning sign, preventing the leaked foreign matter from falling on the LED luminous warning sign 2. At the same time, the LED luminous warning sign 2 is shielded by the awning 9 to prevent rain and snow from falling on the LED luminous warning sign 2 in rainy and snowy weather, thereby facilitating the protection of the LED luminous warning sign 2 and extending the service life of the LED luminous warning sign 2.

[0060] Please refer to Figure 1and Figure 2 A mounting frame 5 is installed at the front end of the pole 1 and between the LED luminous warning sign 2 and the control cabinet 6. A rain and snow sensor 10 is fixedly installed on one side of the top of the mounting frame 5, and a wind speed sensor 11 is fixedly installed on the other side of the top of the mounting frame 5. A light sensor 12 is fixedly installed on the front side of the LED luminous warning sign 2.

[0061] Specifically, during the use of the solar luminous warning sign, when the rain and snow sensor 10 detects rain and snow, or the wind speed parameter detected by the wind speed sensor 11 is greater than or equal to the set wind speed parameter value, or the photosensitive sensor 12 detects that the ambient light is weak, the cleaning and protection mechanism 4 is triggered to close, and the solar panel 301 is protected to prevent rain and snow from falling on the surface of the solar panel 301, and to prevent foreign objects from hitting the solar panel 301 when the wind is strong, causing damage to the solar panel 301, thereby extending the service life of the solar panel 301.

[0062] Please refer to Figure 1 , Fig. 9 , Fig.10 and Fig.11 The wind-resistant mechanism 7 includes a bottom pile 701, a plug rod 702 is centrally arranged on the top of the bottom pile 701, a top pile 703 is fixedly installed on the top of the plug rod 702, the plug rod 702 is sleeved with the bottom pile 701, and the top of the top pile 703 is fixedly welded to the vertical pole 1.

[0063] Please refer to Figure 1 , Fig. 9 , Fig.10 and Fig.11 The wind-resistant mechanism 7 also includes a plurality of slide grooves 706 opened inside the bottom pile 701 and located on both sides of the insertion rod 702. A plurality of sliders 704 are fixedly installed on both sides of the insertion rod 702. An annular spring 705 is fixedly installed at the front and rear ends of the slider 704, and the annular spring 705 is located in the slide groove 706. The slider 704 is slidably connected to the bottom pile 701 through the slide groove 706.

[0064] Specifically, in windy weather, the wind blows onto the solar luminous warning sign. When the wind force is strong and the wind force on the surface of the solar luminous warning sign is uneven on the left and right sides, the vertical pole 1 and the top pile 703 rotate, thereby driving the insertion rod 702 to rotate, and the slider 704 slides along the slide groove 706, two of which are compressed and the other two are stretched. Under the action of wind force, the solar luminous warning sign tilts to a certain extent toward the side with greater force, reducing the force area, thereby improving the wind resistance of the solar luminous warning sign. When the wind force decreases, under the action of the annular spring 705, the vertical pole 1 and the top pile 703 are reset.

[0065] Please refer to Figure 1and Figure 8 The fixing mechanism 8 includes a hoop 801 , and rubber pads 802 are provided on the inner walls of the front and rear ends of the hoop 801 .

[0066] Please refer to Figure 1 and Figure 8 A plurality of fixing components 803 are installed near the bottom of the front and rear ends of the hoop 801 . The fixing components 803 include fixing bolts and fixing nuts. The top of the hoop 801 is fixedly welded to the bottom of the bottom pile 701 .

[0067] Specifically, after removing the fixing component 803, put the hoop 801 on the outside of the frame of the power angle steel tower, then install the fixing component 803, and tighten the fixing bolts and fixing nuts to facilitate the installation of the solar luminous warning sign to the appropriate position of the power angle steel tower, and use the rubber pad 802 to improve the tightness between the fixing mechanism 8 and the power angle steel tower frame.

[0068] How it works

[0069] The solar luminous warning sign is installed at an appropriate position of the electric angle steel tower through the fixing mechanism 8, and the light intensity parameter, humidity parameter and wind speed parameter are set through the control cabinet 6. When the rain and snow sensor 10 detects rain and snow, or the wind speed parameter detected by the wind speed sensor 11 is greater than or equal to the set wind speed parameter value, or the light sensor 12 detects that the ambient light is weak, the servo motor 408 starts and reverses to drive one of the telescopic rods 405 to rotate, and the gear 406 drives the other telescopic rod 405 to rotate. The rotation of the two telescopic rods 405 drives the two protective plates 401 to close, thereby protecting the solar energy storage mechanism 3. When the light sensor 12 detects that the ambient light is weak, the servo motor 408 starts and reverses to drive one of the telescopic rods 405 to rotate, and the gear 406 drives the other telescopic rod 405 to rotate. The rotation of the two telescopic rods 405 drives the two protective plates 401 to close, thereby protecting the solar energy storage mechanism 3. When the sensor 12 detects that the ambient light is strong, the rain and snow sensor 10 does not detect rain and snow, and the wind speed parameter detected by the wind speed sensor 11 is less than the set wind speed parameter value, the servo motor 408 starts and rotates forward to drive the protective plate 401 to unfold. In the process of unfolding the protective plate 401, the surface of the solar energy storage mechanism 3 is cleaned by the velvet cleaning plate 403, and foreign matter attached to the surface of the solar energy storage mechanism 3 is wiped clean to prevent foreign matter from accumulating on the surface of the solar energy storage mechanism 3, covering the light absorption area, and reducing the efficiency of light energy conversion. At the same time, in the process of unfolding the protective plate 401, the surface of the velvet cleaning plate 403 is cleaned by the scraper 304 The foreign matter attached to the surface of the velvet cleaning board 403 is scraped off and leaked out through the leak hole 409, so as to facilitate the removal of the foreign matter attached to the surface of the velvet cleaning board 403. The patch humidity sensor 303 contacts the velvet cleaning board 403 to detect the humidity of the velvet cleaning board 403. When the detected humidity parameter is greater than or equal to the set fixed humidity parameter, the electric heating wire 402 is started to heat and dry the velvet cleaning board 403 to evaporate the moisture on the velvet cleaning board 403, so as to ensure the dryness of the velvet cleaning board 403. In the process of using the solar luminous warning sign, the electric energy converted by the solar energy storage mechanism 3 is used for the LED luminous warning sign 2. Power is supplied and warning information is displayed through the LED luminous warning sign 2. When the environmental wind force is strong and the wind force on the surface of the solar luminous warning sign is uneven on the left and right sides, the vertical pole 1 and the top pile 703 rotate, thereby driving the insertion rod 702 to rotate, and the slider 704 slides along the slide groove 706, two of which are compressed and the other two are stretched. Under the action of wind force, the solar luminous warning sign tilts to a certain extent toward the side with greater force, reducing the force area, thereby improving the wind resistance of the solar luminous warning sign. When the wind force decreases, under the action of the annular spring 705, the vertical pole 1 and the top pile 703 are reset.
