DETAILED DESCRIPTION

[0019] The utility model is described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1-4 As shown, a rainwater collection and utilization device for a collapsible loess residential area comprises a plurality of collection tubes 2 connected in series, the last collection tube 2 being connected to the input end of a water pump 7 via a water pumping pipe 6, and the output end of the water pump 7 being connected to a water storage tank 9 via an output pipe 8.

[0021] A partition 15 is provided in the collecting tube 2, and the partition 15 divides the collecting tube 2 into two upper and lower chambers, the upper one is a buffer chamber 201, and the lower one is a flow chamber 202, and the flow chambers 202 of multiple collecting tubes 2 are connected in series; an opening 17 is provided at the upper end of the collecting tube 2, and a water-permeable net 10 is provided at the opening 17. The water-permeable net 10 is annular, and a cylindrical isolation net 13 is fitted in the center of the water-permeable net 10. The lower end of the isolation net 13 extends into the interior of the collecting tube 2, and the upper end of the isolation net 13 is open and movably connected to a protective cover 11. A through hole 19 is provided in the center of the partition 15, and the bottom of the isolation net 13 is open and connected to the side wall of the through hole 19.

[0022] An annular mounting groove 18 is provided at the opening 17 of the collecting tube 2 , and an annular clamping groove 20 is provided on the outer periphery of the water-permeable net 10 , and the bottom of the clamping groove 20 is clamped in the mounting groove 18 .
