Description

Rainwater harvesting irrigation device for road green belt

Technical field:

The utility model relates to the technical field of highway green belt irrigation.

Background technique:

Due to the lack of precipitation and the poor soil quality for shallow water storage in Northwest my country, the survival rate of vegetation in road green belts is low. It is usually necessary to use water trucks to irrigate regularly along the way to ensure that the vegetation in green belts does not suffer from drought. For example, along the road directly Collecting rainwater and storing it for irrigating green belts has problems such as the traditional storage method is easy to evaporate and lose, and the power energy for irrigation needs to be connected additionally, so it cannot be used in remote areas.

Invention content:

In view of this, it is necessary to design a device that can effectively collect and store rainwater and automatically irrigate road green belts without external power.

Rainwater collection and irrigation devices for road green belts, including: pavement, roadside drainage bricks, roadside drainage plates, water storage tanks, micro-irrigation devices, micro-irrigation pipes, micro-irrigation planting boxes and drip irrigation pipes; where roadside drainage bricks are laid On the side surface of the road surface, the roadside drainage plate is installed under the roadside drainage brick and connected with the side surface of the road surface; there are oblique through holes in the roadside drainage brick, and the roadside drainage plate is attached to the roadside drainage brick and extended to The lower part of the roadbed; the water storage tank is installed under the side of the diversion plate on the road side, and the bottom of the water storage tank facing away from the road is provided with a water storage tank outlet, and a screen is installed in the middle of the water storage tank, and a pebble layer and a covering soil layer are laid in sequence above the screen to store water. The top of the water tank is covered with permeable bricks.

The micro-irrigation device includes a front pump chamber, a rear pump chamber, a leather pad type one-way valve, an air pipe and a filter. Separated from the valve, the top of the front pump chamber and the top of the rear pump chamber are respectively opened.

The air duct is composed of an inner pipe and an outer pipe. The inner pipe is installed in the outer pipe. The top of the outer pipe opens the outer nozzle to the side of the air pipe, and the top of the inner pipe opens the inner nozzle to the side of the air duct opposite to the outer nozzle. The inner pipe and The outer pipes are sealed, the outer pipe mouth points to the windward direction of the installation site, the lower part of the outer pipe is connected with the front pump chamber, and the lower part of the inner pipe is connected with the rear pump chamber; the outlet of the filter is connected to the micro-irrigation planting box and the drip irrigation pipe through the micro-irrigation pipe; The micro-irrigation planting box is filled with water storage.

When there is precipitation, due to the usual waterlogging design of the highway, the rainwater will be guided along the road surface to the side of the road surface, and then led to the water storage tank by the roadside drainage plate. The through holes can also guide water flow and prevent the roadside drainage plate from being damaged. After the rainwater is led to the water storage tank, it is filtered by permeable bricks, covering soil, pebbles and screens and then falls into the bottom area of the water storage tank for storage to prevent algae pollution. The permeable bricks, covering soil and pebbles also serve as a cover to prevent the water storage tank from The water inside evaporates.

When the wind force is strong, a large pressure difference is formed between the windward side and the leeward side of the air duct, forming a state where the outer pipe mouth pressurizes the forward pump chamber and the inner pipe mouth depressurizes the rear pump chamber. The front and rear ends of the pump are equipped with one-way valves. The pressure difference can realize the effect of pressing the water in the front pump chamber into the rear pump chamber, thereby increasing the water level in the rear pump chamber. When there is no wind or the wind force is small, the rear pump The chamber water pressure closes the one-way valve between the front pump chamber and the rear pump chamber, the front pump chamber is filled with water from the water storage tank, and the rear pump chamber relies on the water level pressure to supply water to the micro-irrigation pipe through the filter to realize irrigation. During this process, the filter can limit the flow rate while preventing foreign matter from clogging the outlet of the micro-irrigation pipe and drip irrigation pipe, so that the stored water will not be used up in a short time after precipitation.

Preferably, a polyethylene water-blocking layer is laid on the inner wall of the water storage tank. Under this design, the water storage tank itself can be made of simple materials to reduce costs.

Preferably, the air duct also includes an outer nozzle horn cover, bearings and pointing wind wings, the outer tube mouth horn cover is installed at the outer tube opening, the top of the air duct is installed with the outer nozzle, the part of the inner nozzle and the lower section of the air duct through the bearing Rotatable connection, pointing to the wind wing is Y-shaped wind wing, installed above the inner nozzle, this design is suitable for the installation site where the wind direction is unstable and the wind force is small, the direction of the outer nozzle and inner nozzle can be adjusted at any time by the wind wing, improving wind energy utilization.

The utility model provides a set of specific device design for collecting and storing rainwater and using wind irrigation to realize the automatic irrigation function of road green belts in inland remote areas without external power, especially suitable for the year-round wind in Northwest my country and long sunshine time regional promotion.
