Abstract
The invention discloses a rainwater tank connecting pipeline system for realizing automatic irrigation, which comprises a rainwater tank, a pipeline and a flow choking object, wherein the lower part of the rainwater tank is provided with an outlet; one end of the pipeline is connected with the outlet, and the other end of the pipeline is closed; the pipe wall of the pipeline is provided with a plurality of small holes which are uniformly distributed at equal intervals; the choked flow is filled in the pipe. The rainwater collected by the rainwater tank flows into the pipeline from the outlet under the action of gravity, the resistance is generated on the water flow due to the choked flow filled in the pipeline, so that the flow speed is greatly reduced, the flow and the speed of the water flow in the pipeline are determined according to Darcy's law, a plurality of small holes with equal intervals are formed in the pipe wall of the pipeline, the flowing state of a porous medium is achieved, and the automatic and durable irrigation on green plants around the rainwater tank can be implemented.
Description
Technical Field
The invention relates to the technical field of rainwater comprehensive utilization equipment, in particular to a rainwater tank connecting pipeline system for realizing automatic irrigation.
Background
In sponge city construction, the rainwater tank is widely used, can collect rainwater, and waters nearby green plants when sunny, makes the rainwater obtain comprehensive utilization. In order to implement irrigation, the rainwater tank is connected with a pipeline system controlled by a gate valve, and the gate valve is manually opened during irrigation. Most of the rainwater tanks are placed under overhead bridges of cities, are important components of sponge cities, and play an important role in comprehensive utilization of rainwater.
However, there are some problems with existing rainwater tank irrigation piping systems:
1) the rainwater tank connecting pipeline is controlled by a gate valve and needs to be manually opened, and the workload is huge under the condition that the number of rainwater tanks is large;
2) the rainwater is controlled by the gate valve, the flowing speed is high, and the durable irrigation effect is difficult to achieve.
Therefore, it is an urgent need to solve the problem of providing a rainwater tank connection pipe system for realizing automatic irrigation to achieve a durable irrigation effect.
Disclosure of Invention
In view of the above, the invention provides a rainwater tank connecting pipeline system for realizing automatic irrigation, which can automatically irrigate green plants near a rainwater tank and realize durable irrigation.
In order to achieve the purpose, the invention adopts the following technical scheme:
a rainwater tank connecting pipeline system for realizing automatic irrigation comprises a rainwater tank, a pipeline and a flow choking object, wherein an outlet is formed in the lower part of the rainwater tank;
one end of the pipeline is connected with the outlet, and the other end of the pipeline is closed; the pipe wall of the pipeline is provided with a plurality of small holes which are uniformly distributed at equal intervals;
the choked flow is filled in the duct.
By adopting the scheme, the invention has the beneficial effects that:
rainwater collected by the rainwater tank flows into the pipeline through the outlet under the action of gravity, and due to the fact that choked flow is filled in the pipeline and generates resistance to water flow, the flow rate is greatly reduced, a plurality of small holes with equal intervals are formed in the pipe wall of the pipeline, the flowing state of porous media is achieved, and automatic and lasting irrigation can be conducted on green plants around the rainwater tank.
Further, the flow resisting object is broken stone.
The beneficial effect that adopts above-mentioned further technical scheme to produce is, adopts the rubble to fill in the pipeline, can reach the choked flow effect to the cost is lower, is fit for promoting.
Further, the particle size of the crushed stone is larger than the diameter of the small hole.
The beneficial effect that adopts above-mentioned further technical scheme to produce does, can avoid the rubble to run off from the aperture, influences the choked flow effect.
Compared with the prior art, the rainwater tank connecting pipeline system for realizing automatic irrigation has the advantages that:
1) the gate valve does not need to be manually controlled, and water flow automatically flows in the pipeline under the action of gravity;
2) the water flow speed in the pipeline is slow, the irrigation time is long, and the long-lasting irrigation is realized;
3) the problem of pipeline blockage is not considered, the porous medium flows in the pipeline, impurities enter the pipeline, and only the permeability of choked flow is reduced, and irrigation can still be realized;
4) the production cost is reduced.
