Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further explained below.

Referring to fig. 1 to 4, the drainage device for sponge-based city construction includes a support plate 100, and the support plate 100 is disposed in a U-shaped structure. A plurality of water drainage holes 110 arranged in an array are disposed on two side walls of the support plate 100, and the water drainage holes 110 are arranged in a vertical direction on the side walls of the support plate 100.

The side of the support plate 100 is provided with a water collecting tank 200 and an overflow pipe 210 provided on the water collecting tank 200 to be inserted into the soil, and a shower-shaped nozzle 210a is provided at the rear end of the overflow pipe 210. The overflow pipe 210 is inserted into the soil and sprayed by the shower-shaped nozzle 210a to increase the flow rate penetrating into the soil. A plurality of water seepage holes 220 are formed on the side and bottom of the water collecting tank 200. The water seepage holes 220 are used for enabling filtered water to seep into soil.

The middle portion of the support plate 100 is provided with a loading plate 300 arranged in a horizontal direction, and a lower closed region 410 and a loading region 420 are formed in a drainage space of the loading plate 300 for separating the support plate 100, the loading plate 300 is slidably disposed on two sidewalls of the support plate 100, specifically, a sliding groove 100a is provided on the support plate 100, and a protrusion portion sliding in cooperation with the sliding groove 100a is provided on the loading plate 300, so that the loading plate 300 can be slidably adjusted.

At least one return spring 500 is disposed between the support plate 100 and the carrier plate 300. The return spring 500 in this embodiment is disposed within the lower enclosed area 410.

The bearing plate 300 is further provided with a spring connecting portion 600, the bottom of the spring connecting portion 600 is fixedly connected with the return spring 500, and the side of the spring connecting portion 600 is detachably connected with the bearing plate 300. Specifically, the side of the spring coupling part 600 and the carrier plate 300 may be coupled using a drawer snap structure. The carrying plate 300 is further provided with a handle 300 a.

When the utility model is used, when the loading plate 300 is in the no-load state, the number of the drain holes 110 on the two side walls of the supporting plate 100 is the same as that of the lower closed area 410 and the bearing area 420, that is, the loading plate 300 and the return spring 500 form dynamic balance, assuming that there are 10 drain holes 110 in the vertical direction, when no water flows through the supporting plate 100, there are 5 drain holes 110 exposed in the bearing area 420, and 5 lower closed areas 410, when the water flows into the supporting plate 100 to press the loading plate 300 to adjust the number of the drain holes 110 for draining, the water drained into the supporting plate 100 can be drained into the water collecting tank 200 from the drain holes 110 of the bearing area 420, and then the water is drained into the soil through the overflow pipe 210 of the water collecting tank 200 after reaching a certain capacity, if heavy rainstorm occurs, then the water amount of the water is increased, the return spring 500 is compressed, so that the lower closed, 10 wash ports 110 all drain water, drain into water header 200 with the water of certain water yield in, drain into soil by overflow pipe 210 of water header 200 again and carry out the natural circulation, and the aquatic has solid rubbish will be filtered and stay on loading board 300, reduces when discharge, reset spring 500 lifts up loading board 300 so, and the rubbish of deposit on loading board 300 will be raised this moment, and the rubbish that adsorbs on wash port 110 even also can be hung and fall, makes things convenient for the staff to clear up.

The foregoing shows and describes the general principles, essential features, and advantages of the invention.
