The floating lifting control pipe comprises a water inlet end 4, the water inlet end 4 is connected with a first corrugated hose 5 of a lining steel wire with a fixed length, the rear part of the first corrugated hose 5 is connected with a U-shaped hard pipe 6, the rear part of the U-shaped hard pipe 6 is further connected with a second corrugated hose 9 which is the same as the first corrugated hose 5, the rear part of the second corrugated hose 9 is connected with a water outlet end 10, and the middle part of the U-shaped hard pipe 6 is fixed with a floating body 8 through a stainless steel chain 7. After the water inlet end 4 and the water outlet end 10 are fixed, the floating body 8 can lift under the action of gravity and buoyancy of water, so that the U-shaped hard tube 6 is lifted or restored through the stainless steel chain 7, and the first corrugated hose 5 and the second corrugated hose 9 jointly provide enough deformation to meet the requirement of lifting of the U-shaped hard tube 6.
When the water level rises, the floating body 8 rises, the U-shaped hard pipe 6 rises, the first corrugated hose 5 and the second corrugated hose 9 deform upwards, the floating lifting control pipe cuts off the water outlet of the irrigation tank, and the water flow between the first corrugated hose 5 and the second corrugated hose 9 is cut off; when the water level is reduced, the floating body 8 descends, the U-shaped hard pipe 6 also descends, and the first corrugated hose 5 and the second corrugated hose 9 are restored to the original state, so that the floating lifting control pipe restores the water outlet of the irrigation tank, and the first corrugated hose 5 is communicated with the second corrugated hose 9 through water flow.
The main body of the floating lifting control pipe is arranged in the early stage rain water tank, and the lifting of the floating lifting control pipe is controlled by the water level height of the early stage rain water tank.
The working flow of the system is as follows:
at the time of rainfall
Runoff rainwater on the roof or the waterproof underlying surface with higher terrain of a building enters the early-stage rainwater tank 1 through the rainwater inlet pipe 1-1 arranged at the top of the early-stage rainwater tank 1 by confluence, and the volume of the early-stage rainwater tank 1 is determined according to the early-stage rainwater amount (generally, the early-stage 2-4mm rainfall amount) with heavier pollution, which is required to be drained.
Along with the rapid influx of rainwater, the liquid level in the rainwater tank 1 rises continuously in the earlier stage. The floating elevation control pipe 3-2 provided outside the irrigation tank 3 is elevated due to the liquid level of the early stage rain tank 1.
The first unpowered slow releaser 1-4 arranged in the early rainwater tank 1 is responsible for slowly releasing the early rainwater in the early rainwater tank 1 to the front rainwater discharge pipe 1-5 for discharging, the slow release flow selection of the first unpowered slow releaser 1-4 is determined according to the set time, and the water level of the early rainwater tank 1 is generally reduced to a lower limit value (which can be within the range of 12-48 hours according to the actual situation) within 24 hours.
The flow rate of the outward release of the first unpowered slow releaser 1-4 is very low, the water level of the rainwater tank 1 in the early period rises rapidly during rainfall, and when the water level exceeds the pipe bottom of the communicating pipe 1-2, rainwater enters the precipitation rainwater tank 2 through the communicating pipe 1-2.
The volume of the precipitation rainwater tank 2 is determined according to the irrigation water quantity of the greening area needing irrigation for about 7 days and weeks. The second unpowered slow release device 2-1 is arranged in the precipitation rainwater tank 2, and the flow selection type of the second unpowered slow release device 2 is determined according to the daily irrigation quantity required by the green land to be irrigated.
The water outlet of the second unpowered slow release device 2-1 enters an irrigation tank 3, the irrigation tank 3 is provided with a ball float valve 3-1, and the ball float valve 3-1 is arranged at the water outlet of the second unpowered slow release device 2-1.
The water outlet of the irrigation tank 3 is controlled by a floating lifting control pipe 3-2 arranged at the outer side of the irrigation tank 3. When the precipitation rain water tank 2 starts to feed water, the floating lifting control pipe 3-2 is already in a lifting state. A small amount of rainwater enters the irrigation tank 3 through the second unpowered slow-release device 2-1, the water level in the irrigation tank 3 rises, the ball float valve rises, the water outlet of the second unpowered slow-release device 2-1 is closed, and the second unpowered slow-release device 2-1 stops working.
The floating lifting control pipe 3-2 is lifted, the floating lifting control pipe is disconnected from the irrigation tank to discharge water, the second unpowered slow release device 2-1 stops working, and the irrigation water outlet pipe 3-3 does not discharge rainwater.
When the water level of the precipitation rainwater tank 2 rises to a high level, rainwater subsequently entering the rainwater tank 1 in the earlier stage directly overflows out of the system through the rainwater overflow pipes 1-3 and enters a rainwater pipe network.
The utility model discloses when the rainwater case water level was high in earlier stage, the lift control pipe that floats resumes irrigation tank and goes out water, and irrigation tank can't go out water, and the unpowered slowly-releasing ware delivery port of second is sealed by the ball-cock assembly, and the unpowered slowly-releasing ware of second is out of work. The rainwater stored in the rainwater precipitation tank begins precipitation purification under the condition of basic static state. Because the sedimentation process is basically free of disturbance influence, the sedimentation effect is ensured.
Secondly, after the rainfall is finished
No rainwater enters the early stage rain water tank 1 again, and the water levels in the early stage rain water tank 1 and the precipitation rain water tank 2 are kept at high water levels.
The first unpowered slow releaser 1-4 slowly releases the early rainwater with determined volume; meanwhile, the precipitation rainwater tank 2 has no water inlet and outlet interference, and rainwater is statically precipitated in the precipitation rainwater tank 2.
After rainfall finishes for 24 hours, the first unpowered slow-release device 1-4 discharges the rainwater in the rainwater tank 1 in the early stage to a low position, the floating lifting control pipe 3-2 descends, the floating lifting control pipe recovers the water outlet of the irrigation tank, and the irrigation tank 3 starts to discharge the water.
The water level of the irrigation tank 3 is reduced, the ball float valve 3-1 opens the water outlet of the second unpowered slow release device 2-1, and the second unpowered slow release device 2-1 starts to discharge water.
The rainwater in the precipitation rainwater tank 2 is in a completely static state, the free precipitation time exceeds 24 hours, and the water quality of the upper part of the precipitation rainwater tank is equal to good purification treatment.
The water inlet of the second unpowered slow release device 2-1 is suspended 1-2cm below the liquid level of the water level all the time, so that the rainwater entering during working is clean upper rainwater purified through precipitation, and meanwhile, pollutants precipitated at the bottom of the precipitation rainwater tank 2 are not disturbed.
Clean rainwater slowly released by the second unpowered slow release device 2-1 enters the green land irrigation pipe through the irrigation box 3, the floating lifting control pipe and the irrigation water outlet to start irrigation.
The precipitation rainwater tank 2 is provided with an automatic sewage discharging device 2-2, and after the second unpowered slow release device 2-1 finishes working, a small amount of rainwater with pollutants enriched at the lower part of the rainwater precipitation tank is discharged to a sewage discharging pipe 2-3, so that the influence on the water quality treatment effect caused by the accumulation of the precipitated pollutants in the next rainfall is avoided.
