Automatic collection system for initial rainwater in harbor district

Technical Field

The utility model relates to an automatic collection system for initial rainwater in a harbor area.

Background

China is a country with serious drought and water shortage. The total amount of fresh water resources in China is 28000 billion cubic meters, which accounts for 6 percent of the global water resources and is second only to Brazil, Russia and Canada, the fourth place in the famous world. However, the per capita water resource of China is only 2300 cubic meters, which is only 1/4 on the average level in the world, and is one of the most scarce countries in the per capita water resource of the world.

Rainwater is a relatively cheap recyclable water resource as a natural gas-liquid conversion product. Incipient rain is often defined as sewage, typically as precipitation of surface runoff already formed at 10-15mm thickness of the ground. In the early stage of rainfall, a large amount of acid gases, automobile exhaust, factory waste gas and other pollutant gases in the air are dissolved in the rainwater, and after the rainwater falls to the ground, the rainwater in the early stage contains a large amount of pollutants due to scouring of roofs, asphalt concrete roads and the like, so that the pollution degree of the rainwater in the early stage is higher and even exceeds that of common urban sewage. The initial rainwater is collected and brought into a sewage pipeline, so that the natural water environment can be effectively protected.

At present, an effective technical means is lacked for the linkage collection of initial rainwater of water and land areas in large harbor areas, and great inconvenience is brought to wharf construction and production processes.

Detailed Description

The technical scheme of the utility model is further specifically described by the following embodiments and the accompanying drawings.

The automatic harbor initial rainwater collecting system in the embodiment is used for separating initial rainwater from natural water bodies in two places of land areas and water areas in harbor areas, and plays roles of environmental protection and pollution prevention.

The automatic collection system for initial rainwater in the harbor area comprises a water area collection part:

an open ditch 1 is installed in a water area. Enclosing ridges are arranged on wharfs, approach bridges and the like of the water area part, drainage holes are omitted, a closed area is formed by open ditches, the height of the enclosing ridges is not less than 300mm, and all initial rainwater in the water area is collected to the greatest extent. The water collecting well 2 is communicated with the open ditches 1 and is used for collecting initial rainwater collected by the open ditches. The valve well 3 is provided with a first electromagnetic valve 31 and a second electromagnetic valve 32 in the valve well 3. The first electromagnetic valve 31 is disposed between each open trench 1 and the water collecting well 2. And the second solenoid valve 32 is provided between the open trench and a late stage rain water drain passage 4. When it is just beginning to rain, the rainwater contains more pollutants, and the first solenoid valve 31 is opened, and the second solenoid valve 32 is closed, the water flow enters the water collecting well 2. And the collected rainwater is lifted to the early rainwater reservoir 4 of the land area by adopting a water pump in the water collecting well 2, and is discharged into a sewage pipe network 11 after being treated so as to be treated uniformly. And a first ultrasonic liquid level meter is arranged in the water collecting well 2 so as to monitor the water level in the water collecting well 2 in real time. The first ultrasonic liquid level meter is used for triggering the automatic work of the water pump. When the rainwater reaches the set value, the set value can be a rainfall fixed value or a rainwater PH fixed value, and after the rainwater reaches the set value, the rainwater is relatively clean, the first electromagnetic valve 31 is closed, the second electromagnetic valve 32 is opened at the same time, the rainwater enters the later rainwater discharge channel 5 from the open ditch and is directly discharged into the water body, and the direct pollution of the rainwater to the water body is reduced. In addition, the late stage rain water drainage channel 5 is additionally communicated with the early stage rain water reservoir 4 of the land area and is controlled by a high liquid level control valve. When the water level in the later stage rainwater drainage channel 5 is too high, the high liquid level control valve is opened, and the later stage rainwater drainage channel 5 is drained to the early stage rainwater reservoir 4 in the land area, so that the water drainage of the water area is stable and controllable.

The pipe network 6 is arranged in the land area. A grating 7 is provided, particularly between the pipe network 6 and the land initial rainwater reservoir 4, to take into account the contamination of the land area. A first electric shutter 81 and a second electric shutter 82 are provided in the lock gate shaft 8. The first electric gate 81 is connected to the water inlet pipeline of the pipe network 6 communicated with the grating 7. The second electric shutter 82 is connected to a later stage rainwater drain line 9. When rain begins, rain water is collected by the pipe network 6, the first electric shutter 81 is opened, the second electric shutter 82 is closed, and the collected initial rain flows into the initial rain water reservoir 4 of the land area via the grille. When the rainwater reaches the set value, close first electric gate 81, open second electric gate 82, pipe network 6 is direct to be linked together with later stage rainwater drainage pipeline 9, and the rainwater is direct to be discharged into the water.

In addition, when rainwater reaches a high liquid level in the initial rainwater reservoir 4, the pump of the water pump 10 in the water area water collecting well 2 is controlled in a linkage mode to stop, and the working condition of clean rainwater discharge 5 in the later stage of the water area is switched.

In addition, each sump pit, first solenoid valve, second solenoid valve, pipe network, first electronic gate, second electronic gate and land area initial stage rainwater cistern all send real-time signal and give a visual control system control.
