The utility model content
The purpose of this utility model provides a kind of intelligent first rain online draining device, and described this intelligent first rain online draining device will solve in the prior art easy contaminated technical problem in the rainwater collection process.
A kind of intelligent first rain online draining device of the utility model is by the rainwater water inlet pipe, four-way and water tank constitute, wherein, described rainwater water inlet pipe is connected with a grille well, described grille well is connected with a import in the described four-way, an outlet in the four-way is connected with described water tank, the described outlet in the four-way and the connecting line of water tank are provided with one first motor operated valve, the side of water tank is provided with a fluid level control device, the bottom of water tank is provided with a draining valve, another outlet in the four-way is provided with one second motor operated valve, and the connecting line of grille well and four-way is provided with a first flow inductive switch.
Further, be provided with a bypass duct between the four-way outlet of the four-way import of connection grille well and connection water tank, described bypass duct is provided with one second flow sensing switch.
Further, be provided with the 3rd outlet in the described four-way, be provided with one outlet pipe between described the 3rd outlet and the water tank, described outlet pipe is provided with one the 3rd motor operated valve.
Further, the inside of described grille well is provided with a string bag.
The operating principle of this device is as follows: when beginning to rain, the rainwater band the roof and is washed away the pollutant that gets off and enter grille well along the rainwater pipe, grille well stops oarse-grained impurity, rainwater enters water tank, the flow sensing switch is after receiving the rainwater water-flow signal, send signal to a controller, controller starts first rain and abandons program, abandon drainage pump running time by what the first rainfall that calculates gained in advance was converted to, the first rain in the water tank is drained, when the draining setting-up time reaches, controller output signal, second electrically operated valve is closed, and second electrically operated valve is opened, and makes clean rainwater enter next gathering system.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model has at first saved large-scale first rain and has abandoned the pond, has realized intelligentized online abandoning aspect control, and aspect practicality and economy, its effect is actively with tangible.Grille well of the present utility model can effectively be held back the dirt that washes away, and the abandoning timely and effectively of rain at the beginning of adding guaranteed that the rainwater of cleaning flows into next outlet system, can obtain better utilization after making rainwater processed.
The specific embodiment
As shown in Figure 1, a kind of intelligent first rain online draining device of the utility model, by a rainwater water inlet pipe 1, four-way 3 and water tank 5 constitute, described rainwater water inlet pipe 1 is connected with a grille well 2, described grille well 2 is connected with four-way 3, one first delivery port 4 of described four-way 3 is connected with water tank 5, the connecting line of described first delivery port 4 and water tank 5 is provided with one first motor operated valve 6, one side of described water tank 5 is provided with a fluid level control device 7, the bottom of described water tank 5 is provided with a draining valve 8, second delivery port 9 of described four-way 3 is provided with one second motor operated valve 10, and the connecting line of described grille well 2 and described four-way 3 is provided with a first flow inductive switch 11.
Further, be provided with a bypass duct 12 between first delivery port 4 of the connecting line of described grille well 2 and described four-way 3 and described four-way 3, described bypass duct 12 is provided with one second flow sensing switch 13.
Further, the 3rd delivery port 14 of described four-way 3 is provided with one outlet pipe 15, and described outlet pipe 15 is connected with described water tank 5, and described outlet pipe 15 is provided with one the 3rd motor operated valve 16.
Further, described grille well 3 inside are provided with a string bag.
