Description

Technical Field

[0001] The invention relates to the technical field of street lamp lighting, and in particular to a municipal road lighting street lamp powered by solar energy. Background Art

[0002] Solar street lights are powered by crystalline silicon solar cells, maintenance-free valve-regulated sealed batteries (gel batteries) to store electrical energy, and ultra-bright LED lamps as light sources. They are controlled by intelligent charge and discharge controllers to replace traditional public electric street lights. Solar cell modules generally use monocrystalline silicon or polycrystalline silicon solar cell modules; LED lamp heads generally use high-power LED light sources; controllers are generally placed inside lamp poles and have light control, time control, overcharge and over-discharge protection, and reverse connection protection. More advanced controllers also have functions for adjusting the lighting time in all seasons, half-power function, intelligent charge and discharge function, etc. Solar street lights are widely used in municipal roads.

[0003] Solar panels commonly used in the prior art are usually installed on lamp poles in the open air. As the weather changes in cities, dust is scattered in the air. Solar panels will accumulate a lot of dust during long-term use. If the dust cannot be handled immediately, it will directly interfere with and affect the power generation efficiency of the solar panels, which may lead to insufficient power supply and thus affect the lighting. Lamp poles are generally slender, and it is very troublesome to clean the solar panels, especially for the solar panels on the numerous lamp poles in the city. Cleaning is a relatively time-consuming and labor-intensive project; in addition, common solar panels are usually fixedly installed with a fixed installation angle and a limited top surface area, and the amount of solar energy received is small, especially when used in winter, the solar energy collection efficiency is lower, and it cannot meet the lighting demand for road conditions in winter; in addition, common solar panels are installed in the open air on lamp poles. After long-term use, they are easily affected by solar radiation, weathering, etc., which may affect the sealing of the solar panels. For this reason, we propose a solar-powered municipal road lighting street lamp to solve the above problems. Summary of the invention

[0014] The present invention provides a solar-powered municipal road lighting lamp, which has the following beneficial effects:

[0015] 1. The solar-powered municipal road lighting street lamp is provided with a reflective bowl and a transparent protective cover on the top of the street lamp pole, and a power generation cage is provided at the center of the reflective bowl. When light is irradiated to the inner wall of the reflective bowl, the light can be reflected to the solar panel on the power generation cage, thereby increasing the solar energy receiving area and improving the solar energy utilization efficiency. At the same time, the power generation cage is protected by the transparent protective cover, and the power generation cage is isolated from the outside world to prevent the power generation cage from being damaged by the external environment and to prevent dust from adhering to the surface of the power generation cage and affecting the power generation efficiency.

[0016] 2. The solar-powered municipal road lighting lamp drives the transmission shaft and the cleaning component to rotate by the wind blowing the blades. When the cleaning component rotates on the top of the transparent protective cover, the surface of the transparent protective cover can be cleaned by the cleaning strip in the cleaning component to prevent the deposition of impurities on the surface of the transparent protective cover from affecting the transmittance, thereby ensuring the power generation efficiency of the power generation cage. At the same time, the compression spring applies elastic force to the connecting rod and the cleaning strip, so that the cleaning strip can be tightly attached to the surface of the transparent protective cover, thereby improving the cleaning effect of the surface of the transparent protective cover.

[0017] 3. The solar-powered municipal road lighting lamp collects rainwater through the water collection bin. When the transmission arm rotates, it simultaneously drives the toggle assembly to rotate. The push-type water valve is pressed by the toggle plate to open the push-type water valve for a few seconds, so that the water in the water collection bin can be discharged along the water nozzle on the connecting arm. The auxiliary cleaning strip is used to clean the surface of the transparent protective cover, thereby improving the cleaning effect of the transparent protective cover, further ensuring the light transmittance of the transparent protective cover, and ensuring the power generation efficiency of the power generation cage.

[0030] See also Figure 2 , 3The power generation cage 6 is located at the center of the reflective bowl 3. The light can be reflected between the inner walls of the reflective bowl 3 and finally irradiated to the center of the reflective bowl 3. After the light is reflected on the inner wall of the reflective bowl 3, it irradiates to the solar panel on the surface of the power generation cage 6 to generate electricity.

The toggle assembly 96 includes a mounting seat 961, a toggle plate 962, a return spring 963, and a limit block 964. The mounting seat 961 is fixedly mounted on the transmission arm 91, and the toggle plate 962 is movably mounted on the mounting seat 961. When the cleaning assembly 9 rotates on the top of the transparent protective cover 4, the surface of the transparent protective cover 4 can be cleaned by the cleaning strip 93 in the cleaning assembly 9 to prevent the deposition of impurities on the surface of the transparent protective cover 4 from affecting the transmittance, thereby ensuring the power generation efficiency of the power generation cage 6.

[0033] In summary, when the solar-powered municipal road lighting lamp is in use, light passes through the transparent protective cover 4 and shines on the inner wall of the reflective bowl 3. Since the reflective bowl 3 is in the shape of a bowl as a whole, the light can be reflected between the inner walls of the reflective bowl 3 and finally shine on the center of the reflective bowl 3. After the light is reflected on the inner wall of the reflective bowl 3, it shines on the solar panel on the surface of the power generation cage 6 to generate electricity. The reflective bowl 3 has a large diameter and can receive more solar energy, thereby improving the utilization rate of solar energy by the solar panel on the surface of the power generation cage 6. The wind drives the driving blades 8 to drive the transmission shaft 7 to rotate, thereby driving the cleaning component 9 to rotate on the surface of the transparent protective cover 4. The compression spring 95 applies elastic force to the connecting rod 92 and the cleaning rubber strip 93, so that the cleaning rubber strip 93 is closely attached to the surface of the transparent protective cover 4, and impurities on the surface of the transparent protective cover 4 are removed. Efficient cleaning is carried out to ensure the light transmittance of the transparent protective cover 4 and the power generation efficiency of the solar panels on the surface of the power generation cage 6. Rainwater is collected by two groups of water collection bins 10 and filtered by filter cotton 14 for use in cleaning the surface of the transparent protective cover 4. When the cleaning component 9 rotates, the transmission arm 91 drives the toggle component 96 to rotate synchronously. When the toggle component 96 rotates to the position of the water collection bin 10, the push-type water valve 13 is pressed by the toggle plate 962 to open the push-type water valve 13 for several seconds. The rainwater inside the water collection bin 10 enters the water guide pipe 12 and is discharged along the water nozzle. The auxiliary cleaning strip 93 cleans the surface of the transparent protective cover 4. When the cleaning component 9 continues to rotate, the toggle plate 962 can squeeze the reset spring 963 to flip over to ensure that the cleaning component 9 can rotate continuously.
