DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figures 1 to 5 As shown, an energy-saving landscape lighting device according to an embodiment of the present invention includes a lower support 1, a support frame 12 is fixed to the top of the lower support 1, a lamp body 11 is installed inside the support frame 12, an upper support 13 is fixed to the top of the support frame 12, and a built-in energy storage battery is installed inside the lower support 1; The photovoltaic panel body 2 is hingedly connected to the four sides of the top of the upper support 13. The photovoltaic panel body 2 is electrically connected to the energy storage battery inside the lower support 1 through wires. The bottom of the upper support 13 is provided with four drainage holes 131, which are respectively close to the four edges of the top of the lamp body 11. The second motor 213 is installed inside the upper support 13. The second motor 213 drives the four photovoltaic panel bodies 2 to rotate simultaneously, and the four photovoltaic panel bodies 2 rotate upward to form a deflector, and guide rainwater to the surface of the lamp body 11 through the drainage port 131; A lighting device is usually installed near the landscape garden. The lighting device can supplement the exterior of the landscape when the ambient light is weak, so that the exterior of the decoration is more conducive to the viewing of pedestrians. When using the lighting device, first install the device and transport the device to the location where it needs to be installed. Then, the bottom of the lower support 1 is oriented and aligned with the hole position of the installation position, and the fastener is passed through the installation hole at the bottom end of the lower support 1, and the lower support 1 is fixed to the installation position by the fastener. Then, the external power supply circuit is connected to the interior of the lower support 1. At the initial stage of use, the lamp body 11 is powered by the external power supply. The lamp body 11 is powered on at preset sunrise and sunset times for illumination. A built-in controller is installed inside the lower support 1 to control the on / off of the lamp body 11. In order to save electricity consumption of the lamp body 11 at night, a photovoltaic panel body 2 is provided. A photovoltaic panel is installed on the upper surface of the photovoltaic panel body 2. On sunny days, sunlight shining on the upper surface of the photovoltaic panel body 2 will generate electricity through the photovoltaic panel. The electricity is introduced into the energy storage battery inside the lower support 1 through a wire. The energy storage battery stores the electricity. At night, the controller controls the energy storage battery to release the electricity to power the lamp body 11, causing it to emit light and provide supplementary lighting for decorative objects. The photovoltaic panel body 2 can change its angle during use by the rotation of the second motor 213. In the case of daily power generation, the photovoltaic panel body 2 is in Figure 1 In the flat state, the photovoltaic panels of the photovoltaic panel main body 2 can receive more light, which is more convenient for photovoltaic power generation. When it rains, the photovoltaic panels of the photovoltaic panel main body 2 cannot generate electricity. At this time, they can be cleaned. On rainy days, the second motor 213 first drives the four photovoltaic panel main bodies 2 to rotate downward. At this time, the two sides of the four photovoltaic panel main bodies 2 contact each other to form a quadrangular pyramid shape. At this time, rainwater will contact the photovoltaic panels of the photovoltaic panel main body 2, which can flush the surface of the photovoltaic panel main body 2, and can prevent the surface of the photovoltaic panel main body 2 from being affected by too much dust and affecting the power generation effect. , then the second motor 213 drives the photovoltaic panel body 2 to rotate upward until the two side edges of the four photovoltaic panel bodies 2 contact each other. At this time, the four photovoltaic panel bodies 2 form a deflector, and the deflector can collect rainwater and divert it downward. The rainwater is guided to the outer surface of the lamp body 11 through the drain port 131. At this time, the outside of the lamp body 11 can be washed by rainwater. In this way, the outer surface of the lamp body 11 can be cleaned without causing damage to the outside of the lamp body 11. The connections between the lamp body 11 and the lower support 1 and the upper support 13 are sealed to prevent rainwater from seeping in.

[0024] like Figures 1 to 5As shown, a lifting chamber 132 is provided inside the upper support 13, and a lifting frame 211 is slidably connected to the interior of the lifting chamber 132. The ends of the lifting frames 211 are rotatably connected to the support rods 21, and the other ends of the support rods 21 are rotatably connected to the bottom end of the photovoltaic panel body 2. A threaded rod 212 is fixed to the end of the rotating shaft of the second motor 213, and the threaded rod 212 is threadedly connected to the lifting frame 211. The second motor 213 drives the lifting frame 211 to move up and down in the lifting chamber 132 to control the angle of the photovoltaic panel body 2 to turn up and down. In the initial state, the lifting frame 211 is in the middle of the lifting chamber 132. At this time, the photovoltaic panel main body 2 is in a horizontal state at the top of the upper support 13. At this time, the photovoltaic panel at the top of the photovoltaic panel main body 2 is more convenient for receiving sunlight to generate electricity. When the photovoltaic panel main body 2 needs to change its angle, the second motor 213 is started to drive the threaded rod 212 to rotate. At this time, the threaded rod 212 drives the lifting frame 211 to perform lifting movement inside the lifting chamber 132. During this process, the lifting frame 211 drives the photovoltaic panel main body 2 to rotate at the top of the upper support 13 through the support rod 21. When the lifting frame 211 moves to the bottom end of the lifting chamber 132, the four photovoltaic panel main bodies 2 form a quadrangular pyramid shape. When the lifting frame 211 moves to the top of the lifting chamber 132, the four photovoltaic panel main bodies 2 form a guide cover, which can realize the change of the angle of the photovoltaic panel main body 2 and limit the rotation angle of the photovoltaic panel main body 2.

[0025] like Figures 1 to 6 As shown, a guide port 144 is formed at the top of the upper support 13, a guide pipe 145 is fixed to the middle of the lifting chamber 132, and a liquid inlet chamber 133 is formed inside the upper support 13. The liquid inlet chamber 133 is connected to the four drain ports 131, and the guide port 144 is connected to the interior of the liquid inlet chamber 133 through the guide pipe 145; When the drain outlet 131 is used to clean the outer surface of the lamp body 11, the water flow needs to be directed into the liquid inlet cavity 133. When the four photovoltaic panel bodies 2 form a deflector, the rainwater is guided by the photovoltaic panel body 2 and flows into the inside of the diversion port 144. At this time, the diversion port 144 transports the rainwater to the inside of the liquid inlet cavity 133 through the diversion pipe 145. The liquid inlet cavity 133 can transport the rainwater to the position of the drain outlet 131. The drain outlet 131 guides the rainwater to the outer surface of the lamp body 11. At this time, the dust on the outer surface of the lamp body 11 is carried away by the flow of rainwater, and the outer surface of the lamp body 11 can be cleaned by the flow of rainwater.

[0026] like Figures 1 to 6 As shown, a sliding hole is opened in the middle of the lifting frame 211, and the guide tube 145 passes through the sliding hole of the lifting frame 211; During the lifting process of the lifting frame 211, in order to prevent the guide tube 145 from affecting the lifting frame 211, a sliding hole is provided in the middle of the lifting frame 211. When the lifting frame 211 is lifted or lowered, the sliding hole can prevent the lifting frame 211 and the guide tube 145 from contacting each other, thereby preventing the guide tube 145 from affecting the lifting process of the lifting frame 211.

[0027] like Figures 1 to 7 As shown, the interior of the liquid inlet cavity 133 is rotatably connected to a rotating tube 15, and a guide nozzle 151 is fixed to the bottom end of the rotating tube 15. The guide nozzle 151 can rotate at the bottom end of the liquid inlet cavity 133; After rainwater enters the liquid inlet chamber 133, the distribution of rainwater to the four drain outlets 131 is prone to unevenness, resulting in different amounts of water output by the four drain outlets 131 to the outer surface of the lamp body 11, and the cleaning effect will be affected. At this time, the water flow inside the liquid inlet chamber 133 is diverted by rotating the tube 15, and output through the diversion nozzle 151 to the position where it passes through the drain outlet 131, thereby realizing one-way water supply to one drain outlet 131, and turning the diversion nozzle 151 90° at a preset time interval, thereby switching the diversion nozzle 151 to supply water to different drain outlets 131. At each time, the drain outlet 131 only flushes one side of the lamp body 11, and the larger the water volume, the better the flushing effect.

[0028] like Figures 1 to 7 As shown, a toothed disc 152 is fixed to the top of the rotating tube 15, and a first motor 153 is provided on one side of the rotating tube 15. An output gear 154 is fixed to the end of the rotating shaft of the first motor 153, and the output gear 154 is meshedly connected with the toothed disc 152; When the diversion nozzle 151 needs to turn, the first motor 153 is started to drive the output gear 154 to rotate. At this time, the output gear 154 can drive the toothed disc 152 to rotate, and the toothed disc 152 can drive the diversion nozzle 151 to turn through the rotating tube 15. When the preset time is reached, the first motor 153 rotates to drive the diversion nozzle 151 to rotate 90° and stop, thereby automatically switching the diversion nozzle 151 to supply water to the drain outlet 131 in different directions.

[0029] like Figures 1 to 6 As shown, a sealing block 14 is provided above the guide port 144 , and the sealing block 14 can be engaged inside the guide port 144 ; When the lifting frame 211 drives the photovoltaic panel body 2 to flip upward, the sealing block 14 will be driven to rise from the inside of the guide port 144; When the photovoltaic panel main body 2 is laid flat, water does not need to enter the interior of the guide port 144. Therefore, dust and impurities will float in when the guide port 144 is open. When the impurities are large in volume, they may cause blockage of the interior of the guide port 144. Therefore, a sealing block 14 is set above the guide port 144. When the photovoltaic panel main body 2 is laid flat, the sealing block 14 will be placed inside the guide port 144. At this time, the sealing block 14 can block the guide port 144 to prevent impurities from entering the interior of the guide port 144. When the photovoltaic panel main body 2 is flipped upward, the guide port 144 needs to be opened. At this time, the lifting frame 211 will drive the sealing block 14 to rise, so that the interior of the guide port 144 can be opened.

[0030] like Figures 1 to 6 As shown, lifting rods 141 are fixed on both sides of the sealing block 14, and lifting holes 143 are opened on both sides of the upper support 13. The lifting rods 141 are slidably connected to the inside of the lifting holes 143. A spring 142 is fixed to the top of the lifting hole 143, and the bottom end of the spring 142 is fixedly connected to the lifting rod 141; When the sealing block 14 and the guide port 144 are closed, the bottom end of the lifting rod 141 is at the middle height of the lifting cavity 132; When the lifting frame 211 rises from the middle of the lifting chamber 132, the lifting frame 211 will contact the bottom of the lifting rod 141. At this time, the lifting rod 141 is pushed up and the spring 142 is squeezed. When the lifting rod 141 rises, it pushes the sealing block 14 to rise from the inside of the guide port 144. When the lifting frame 211 drives the photovoltaic panel body 2 to reset, the bottom end of the lifting rod 141 loses the thrust of the lifting frame 211. At this time, the elastic force of the spring 142 pushes the lifting rod 141 to move downward. When the lifting rod 141 moves downward, it drives the sealing block 14 to move downward and re-enter the inside of the guide port 144, so that the inside of the guide port 144 is sealed again.

[0031] like Figures 1 to 8 As shown, a diversion cavity 16 is provided around the interior of the lower support 1. A water outlet 161 is provided at the bottom of the diversion cavity 16, and a water inlet 162 is provided at the top of the diversion cavity 16. The water inlet 162 is close to the edge of the lamp body 11. When the lamp body 11 is flushed, a large amount of water is generated, and impurities carried away by the water are likely to remain on the surface of the lower support 1. Therefore, a diversion chamber 16 is provided. When the lamp body 11 is flushed, sewage flows into the interior of the diversion chamber 16 through the water inlet 162. The sewage is guided by the diversion chamber 16 to the bottom of the lower support 1 and is discharged from the interior of the diversion chamber 16 under the guidance of the water outlet 161. During this process, the sewage will not pass through the outside of the lower support 1, which can prevent impurities in the sewage from remaining on the surface of the lower support 1.

[0032] like Figures 1 to 10As shown, a baffle 17 is provided above the water inlet 162. A connecting shaft 172 is fixed to the side of the baffle 17 away from the lamp body 11. Steering gears 174 are fixed to both sides of the connecting shaft 172. Coil springs 173 are fixed to the outside of both ends of the connecting shaft 172. The other end of the coil spring 173 is fixed to the lower support 1. A gear column 175 is meshed and connected between two adjacent steering gears 174. A lifting frame 171 is fixed to the top of the gear column 175. When the lifting frame 211 is lifted to the top of the lifting chamber 132 , the lifting frame 171 is pushed to the top of the lifting chamber 132 ; In daily use, impurities easily enter the position of the water inlet 162, resulting in obstruction of water flow. A baffle 17 is set at the top of the water inlet 162. In daily use, the baffle 17 can block impurities above the water inlet 162. When the photovoltaic panel body 2 is turned up, the water inlet 162 needs to be opened. At this time, the lifting frame 211 rises to the top of the lifting chamber 132, and the lifting frame 211 pushes the pulling frame 171 to rise, which can drive the gear column 175 to rise. At this time, the gear column 175 drives the steering gear 174 on both sides to rotate 90 degrees, and the steering The gear 174 drives the baffle 17 to rotate 90° to the side away from the lamp body 11 through the connecting shaft 172. At this time, the top of the water inlet 162 is opened. When the photovoltaic panel body 2 is reset, the lifting frame 211 descends, the pulling frame 171 loses thrust, and the elastic force of the coil spring 173 drives the connecting shaft 172 to rotate 90° in the opposite direction. At this time, the connecting shaft 172 drives the baffle 17 to rotate in the opposite direction and reset. At the same time, the connecting shaft 172 drives the gear column 175 to move in the opposite direction and reset, so that the baffle 17 can be automatically opened and closed, and the upper part of the water inlet 162 can be protected in time.
