Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example.

Referring to Figure 1-2, an urban waterlogging prevention and drainage device includes a water storage tank 1 buried below the ground and a water collection ditch 3 above the ground, and a water collection pipe 4 is connected above the side wall of the water storage pool 1, and the water collection pipe 4 The water inlet end communicates with the bottom of the sump 3, the top of the reservoir 1 is connected with a cover plate 2, the bottom surface of the cover plate 2 is equipped with a second water pump 6 and a plurality of first water pumps 5, the first water pump 5 The outlet end is connected with a first drainage pipe 7, the other end of the first drainage pipe 7 is connected with a municipal drainage pipe 8, the water inlet end of the second water pump 6 is connected with a suction pipe 9, and the bottom end of the suction pipe 9 is suspended from the water storage. Above the bottom of the pool 1, the outlet end of the second water pump 6 is connected with a second drainage pipe 10, the outlet end of the second drainage pipe 10 is connected with a municipal river 11, and the top surface of the cover plate 2 is connected with a support frame 12, the support frame Display 13 is installed on the top of 12, and controller 14 is installed on the side of support frame 12, and controller 14 adopts STC90C51 type single-chip microcomputer as main control chip, and controller 14 is connected with the first water pump 5, the second water pump 6 and display 13 respectively.
