Fig. 1 is used for user mode (i.e. the quick drainage system of ponding under the bridge) figure of draining under the ground bridge for the present invention.
Said quick drainage system comprises the diving pneumatic pump 7 that is arranged in underground tank 5, the gas holder 14 that is arranged in basement 10 and air compressor 9; The end of said underground tank 5, be lower than the ground 1-5 rice under the ground bridge; Said underground tank 5 successively through underground tank intake pipe 3, be positioned at that ponding 2 is connected under the filter screen of ground under the bridge and the ground bridge; The drain opening of said diving pneumatic pump 7 is connected with underground main drainpipe road, city 4 through the waste pipe 6 that safety check 28 is housed; The air outlet of said air compressor 9 is connected through the suction port of gas holder suction tude 13 with gas holder 14; The air outlet of said gas holder 14 is connected with the suction port of diving pneumatic pump 7 through the gas holder outlet pipe 8 that solenoid valve 12 is housed;
Said underground tank intake pipe 3 is more than two.
The working procedure of said drainage system is (referring to Fig. 1-2) as follows:
1, subsequent use to the gas holder inflation:
It is subsequent use to gas holder 14 inflations to start air compressor 9 in the low power consumption period (like night during low-price electricity), autostop when the gas holder internal air pressure reaches 1.2Mpa.
2, the working procedure of diving pneumatic pump:
At first, adjust upward pressure regulation sleeve pipe 34, make spring 38 promote piston rod 27 and move upward, drive the valve plate 33 of intaking down and open; Instantly the valve plate 33 of intaking is run into when playing guide thimble 32, because the active force of spring 38 spurs cylinder body 24 and moves downward, exhaust valve plate 15 is opened exhaust valve plate 15 to bottom offset in the drive again.
When raining heavily, ponding 2 flows to underground tank 5 along underground tank intake pipes 3 and moment is full of diving pneumatic pump 7 under the ground bridge, and float 42 moves upward and makes magnet ring 41 contacts go up magnetic switch 43; Solenoid valve 12 energized are also opened, and the pressurized gas in the gas holder 14 force piston rod 27 to move downward through in the upper gas chamber in first flexible pipe, the 46 entering cylinders; Driving the valve plate 33 of intaking down closes rapidly; Under the effect of spring 38, cylinder body 24 moves upward, and exhaust valve plate 15 is closed simultaneously; Meanwhile; Touching lever 21 bumps and drives air valve 18 into, and pressurized gas get into the pump housing 24 from the outlet pipe 16 of suction valve 18, and the pressure of pressurized gas forces the water in the diving pneumatic pump 7 from outlet pipe 6, to enter in the underground main drainpipe 4 in city through safety check 28.
Along with the water level in the diving pneumatic pump 7 reduces, float 42 moves downward, and drives magnet ring 41 approaching magnetic switch 36 down; Solenoid valve 12 cuts out; Pressurized gas in the cylinder enter atmosphere through first flexible pipe 46, solenoid valve outlet pipe 11 successively, and moment is opened down water inlet valve plate 33 and last exhaust valve plate 15, and moment is full of the pneumatic pump 7 of diving under water to the water in the underground tank again; Go round and begin again, with the 2 row's light of ponding under the ground bridge.Automatically inflation again when the air pressure in the gas holder 14 is reduced to 1.1Mpa.
When the air pressure in the gas holder 14 were reduced to 0.2Mpa, the diving pneumatic pump still can draining, if the capacity of gas holder 14 is 100m
3The time, but water displacement is 1000 m
3
