As shown in FIG. 1 , a drainage street lamp for a sponge city provided by the present invention includes a street lamp body, a solar power generation device and a filtering and drainage device,

Among them, the street lamp body is fixed on the ground, and the street lamp body includes a bulb 3, an outer tube 4, an inner tube 5, a waterproof coating 6, a street lamp base 9 and a maintenance door 8; the gap between the outer tube 4 and the inner tube 5 is placed. , the inner side of the inner tube 5 is a waterproof coating 6, which can ensure the smooth inflow of rainwater. The bulbs 3 are installed on the outer wall of the outer tube 4 on the top of the street lamp body, and two bulbs are placed every 45°. The maintenance door 8 is connected to the inner tube 5 and the outer tube 4. The street lamp base 9 is a reinforcement device and is placed on the ground to prevent the street lamp from tilting. damage.

The solar power generation device includes a solar panel 1 and a battery; the solar panel 1 is laid at the uppermost junction of the outer tube 4 and the inner tube 5 to realize the utilization of clean energy.

As shown in Figures 2 and 3, the filtering and draining device includes a primary filter screen 2 and a secondary filter screen 7. The primary filter screen 2 is arranged on the uppermost layer of the street lamp body, which can filter out impurities such as leaves mixed in the rainwater and avoid entering For the blockage problem that may occur in the lower part of the inner pipe 5, the secondary filter screen 7 is arranged in the middle and lower part of the street lamp body, and three layers are arranged to filter the small debris mixed in the rainwater to avoid the pollution of the rainwater by impurities.

Preferred examples of the present invention will be further described.

Based on the above-mentioned basic embodiment, the solar panel 1 is arranged in a regular octagonal annular design, with a wide and continuous outer edge, which can provide a temporary rain shelter for pedestrians.

Based on the above-mentioned basic embodiment, a light reaction sensor and a rotating device are set between the gap between the inner tube 5 and the outer tube 4 on the top of the street lamp body, the rotating device is driven by the controller, and the tilt angle is automatically adjusted by setting to increase the sunlight exposure. The receiving area increases the utilization rate of the solar panel 1 .

Based on the above-mentioned basic embodiment, the mesh number of the primary filter screen 2 is greater than the mesh number of the secondary filter screen 7, and the mesh number of each layer of the filter screen in the secondary filter screen 7 is the same, so that when the first layer is blocked, it can be timely Remove it, continue to exert the effect of secondary filtration, and do not need to replace the secondary filter immediately.

Variations of the present invention will be further described.

working principle:

On sunny days, the solar panel 1 absorbs solar energy and is used for lighting the lamp body at night. When it is not raining, the primary filter screen 2 plays the role of preventing sundries from falling into the inner tube.

When it rains, the rainwater enters the inner pipe 5 through the inclined surface of the solar panel 1 and/or the primary filter screen 2 due to gravity. The larger pores of the primary filter screen 2 not only ensure the filtering effect, but also ensure that the rainwater can flow into the inner pipe smoothly and quickly. 5. The waterproof coating 6 isolates the rainwater from contacting the inner wall of the inner pipe 5, thereby preventing the corrosion of the inner pipe. The pores of the secondary filter screen 7 are slightly smaller than the primary filter screen 2 to achieve further filtering purposes. Finally, rainwater enters the rainwater pipeline along the bottom of the inner tube 5 of the street lamp, thereby realizing the secondary utilization of rainwater resources in the sponge city.

After a long period of operation, the maintenance door can be opened to check the damage and blockage of the secondary filter, and adjust the position of the filter or replace the filter according to the actual situation.
