Description

An automatic rain-collecting micro-sprinkler irrigation device for green belts

technical field

The utility model relates to a sprinkler irrigation device, in particular to an automatic rain-collecting micro-sprinkler irrigation device for green belts.

Background technique

With the rapid development of my country's urban road green belt planting, its irrigation water consumption is also increasing rapidly. The irrigation methods of road green belts are mainly watering with sprinklers and artificial flooding. The disadvantages of doing this are: 1. High labor intensity, time-consuming and water-consuming, resulting in great waste of water, energy and manpower. 2. Sprinklers occupy the roadway for irrigation operations, and the speed is slow, which affects the passage of other vehicles. It often causes congestion on urban expressways, and traffic accidents also occur from time to time. 3. The sprinkler not only consumes a lot of water, but also the quality of irrigation is not high. The seeping water will cause road water damage. 4. Sprinklers generally have two purposes for sprinkling water, one is to irrigate, and the other is to clean the green belts. Planting species with deep root systems such as trees and shrubs requires a large amount of water and takes too long to irrigate.

With the increasingly tense water resources and the increasing water demand for green belt maintenance, rainwater as a water resource has been paid more and more attention. The utilization of rainwater resources in urban roads has a great impact on the conservation of groundwater sources, improvement of water resource environment, and reduction of drainage pipe network load. , It is of great significance to reduce the investment in rainwater pipelines, alleviate the pressure of urban water use, and reduce the cost of green space maintenance. For this reason, there are many technical reports on how to maintain urban road green belts recently. The Chinese patent "Urban Road Green Belt Decentralized Rainwater Collection and Infiltration Irrigation Device" (application number 200710304179. The rain infiltration irrigation device, the scheme is to set up a decentralized rain collection and infiltration irrigation device next to the city street, such as close to the road shoulder stone, connected to the infiltration irrigation pipe, and the infiltration irrigation pipe leads to the greenery that needs to be irrigated. In the soil with roots, to achieve the purpose of using rainwater to irrigate the plants on the green belt. The disadvantages of this scheme are:

1. Because the seepage irrigation pipes are densely buried underground, with this technical solution, the engineering volume is large and easy to be blocked.

2. In this technical solution, the irrigation water flows completely by the atmospheric pressure or the gravity of the water, and no other power device is provided. Therefore, it is difficult for the irrigation water to flow far enough.

3. In case the seepage irrigation pipe is blocked for some reason, such as people stepping on it or the pressure of a vehicle, it will be difficult for the maintenance personnel to find out in time, and the plant may have been damaged when found.

4. The terrain of the green belt in general cities is higher than that of the road, which makes the embedding and seepage irrigation pipes in a dilemma. One is that the terrain of the green belt is higher than the road, and water cannot seep into the green belt by natural power. Second, if the water must be infiltrated If it is irrigated to the direction of the green belt, the trench for placing the seepage irrigation pipe under the green belt must be dug deeper, that is to say, the distance between the surface of the green belt and the seepage irrigation pipe is relatively large, which will result in low irrigation efficiency.

5. The workload of buried seepage irrigation pipe is heavy and difficult to maintain.

Contents of the invention

The purpose of the utility model is to improve the defects of the prior art, and provide a rain-collecting automatic micro-sprinkler irrigation device for green belts with simple and practical structure, low cost, wide application and easy maintenance.

In order to achieve the above object, the utility model provides an automatic micro-sprinkler irrigation device for collecting rain in green belts, the micro-sprinkler irrigation device includes a rainwater collection device, and the rainwater collection device includes a water collection filter tank and a water storage well, and the water collection filter tank is It is open and covered with a filter water grate, the water storage well is a sealed well, and the lower part of the water collection filter tank is provided with a water outlet connected to the water storage well; the water storage well is connected with an irrigation water pipeline, and the irrigation water pipeline It leads to the green belt that needs to be irrigated, and can be installed on the ground or buried shallowly in the ground; the micro-sprinkler irrigation device also includes a water pump, a water pump opening and closing device and a soil moisture sensor; the water pump and the water pump opening and closing device are installed in the storage In the well, and the water outlet of the water pump is connected with the irrigation water pipeline; the soil moisture sensor is installed in the root soil of the green belt to be irrigated, and the soil moisture sensor and the water pump are respectively connected with the water pump opening and closing device connect.

Further, a low water level controller is provided at the bottom of the water storage well, and the low water level controller is connected with the water pump opening and closing device.

Further, an overflow port is provided on the upper part of the water collection filter tank, and the overflow port communicates with the urban drainage system.

Further, the irrigation water pipeline is provided with a rotary micro-sprinkler.

Further, gravel and/or coarse sand filter materials are provided at the lower part of the water collection filter tank for filtering rainwater.

Further, in order to better filter the rainwater, a slit plate is provided at the water outlet at the lower part of the water collection filter tank.

The working principle of this micro-sprinkler irrigation device is: when there is rainfall, the collected rainwater is deposited and filtered through the water collection filter tank and then stored in the water storage well. When the soil moisture content around the roots of plants planted in the green belt is reduced to a certain level When the soil moisture sensor installed around the plant root system sends out a signal, the water pump opening and closing device starts the water pump, and the pumped water passes through the irrigation water pipeline for irrigation. When the soil moisture content around the plant root system reaches a certain value, the soil around the root system The moisture sensor sends out a signal, and the water pump opening and closing device will stop the water pump. In addition, when the water level in the water storage well is lower than the water pump position, in order to avoid damage to the water pump, the low water level controller set at the bottom of the water storage well will shut down the water pump in time.
