Description

Garden automatic irrigation system

technical field

The utility model relates to the technical field of garden irrigation, in particular to an automatic garden irrigation system.

Background technique

Garden landscaping is about creating a green environment through garden lawns and plants. Modern gardens, while focusing on the construction of landscape sketches, are committed to the improvement of the ecological environment. Build a garden-style city, arrange green space systems, roads and recreational places throughout the city, realize urban gardening, and build natural ecological parks including road landscapes and green forests and lawns. These are all for the purpose of beautifying the city, making the city more beautiful and people In more harmony with nature. Garden irrigation is an important part of garden maintenance.

Authorized announcement number is that the utility model patent of CN203788831U discloses a kind of garden automatic irrigation system. The utility model patent saves water resources by laying seepage pipes. But there is following problem in this utility model: under the situation of rainy day or other sufficient water, this irrigation system still can continue to irrigate, causes the waste of water resources.

Utility model content

The purpose of the utility model is to provide a garden automatic irrigation system which can automatically judge whether the water in the soil is sufficient.

The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: an automatic irrigation system for gardens, including a water storage tank, the water storage tank is provided with a plurality of water delivery pipes, and the water delivery pipes are all equipped with control A control valve for turning on and off the water delivery pipeline. The control valve is provided with a soil moisture sensor that controls the opening and closing of the control valve through a feedback signal. The end of the water delivery pipeline is connected with an irrigation device.

Through the above technical scheme, since the soil moisture conditions of each garden plot are different, soil moisture sensors are installed in multiple garden plots that need to be irrigated, and the soil moisture sensor senses the humidity in the soil. When it is low, the control valve is opened, so that the water stored in the water storage tank can pass through the water pipeline channel irrigation device, and then irrigate through the irrigation device, and the soil humidity increases. When the signal fed back by the soil moisture sensor reaches the set value, the control valve is closed and irrigation is no longer performed. Since the most suitable soil moisture for different plants planted in different gardens is different, this setting can make different plants get a suitable growth environment, making the garden automatic irrigation system more applicable.

It is further provided that: the irrigation device also includes a drip irrigation pipe for slowly dripping water to maintain soil moisture.

Through the above technical scheme, when the soil humidity of the garden land is lower than the upper limit of the most suitable soil humidity for plants, the drip irrigation pipe is controlled to slowly drip water, delaying the decline rate of soil humidity, so that the soil humidity can be maintained within the range of the most suitable soil humidity for plants for a long time .

It is further provided that: the drip irrigation pipe is provided with a detachable drip irrigation device.

Through the above technical scheme, since drip irrigation is prone to blockage, a detachable drip irrigation device is provided on the drip irrigation pipe for drip irrigation. When the drip irrigation device is blocked, it can be put into use only by replacing it with a new drip irrigation device, which is very convenient.

It is further set that: the drip irrigation device is provided with a plurality of water outlets, and the water outlets are all provided with filter screens.

Through the above technical solution, multiple water outlets are provided on the drip irrigator, so that even if some of the water outlets are blocked, the drip irrigator can still be used. A strainer is provided at the water outlet to prevent mud from clogging the water outlet.

It is further provided that: the irrigation device includes a rotary sprayer capable of spraying a large amount of water in a short time.

Through the above technical scheme, when the soil humidity in the garden is less than the lower limit of the most suitable soil humidity for plants, a large amount of water is sprayed through the rotary sprayer to increase the soil humidity, and the salt accumulated due to drip irrigation can be dissolved and washed away, so that the soil will not be salty. change.

It is further set as follows: the rotary sprayer includes a spray base, a spray head that is rotatably connected to the spray base is provided above the spray base, a cylindrical water inlet channel is provided in the center of the spray head, and a spray head is provided on the upper side of the spray head. A water outlet channel whose axis line is tangent to the side of the water inlet channel, and the water outlet channel is provided with an atomizing block for atomizing the water flow.

Through the above technical scheme, the water flow passes through the cylindrical water inlet channel in the center of the spray head, and then sprays out from the water outlet channel whose axis line is tangent to the side of the water inlet channel, and the atomization block arranged in the water storage channel makes the sprayed water mist change. Since the spraying direction of the water flow is tangent to the side of the water inlet channel, the reaction force to the spray head is the force that drives the spray head to rotate. Since the spray head is rotatably connected to the spray base, the spray head rotates while spraying.

It is further provided that: the rotary sprayer is provided with a booster pump for increasing water pressure.

Through the above-mentioned technical solution, since the atomization of the water flow through the rotary sprayer must have a relatively large water pressure, a booster pump is provided to increase the water pressure.

It is further configured to: further include a soil temperature sensor, and the water storage tank is provided with a heating rod controlled to be opened and closed according to the feedback signal of the soil temperature sensor.

Through the above technical solution, when the weather is cold, the temperature of the soil will be low, which is not suitable for plant elongation, so a soil temperature sensor is installed, and when the soil temperature sensor detects that the soil temperature is low, start the heating rod to heat the water storage tank The water in the water allows the plants to be irrigated with warm water and grow better.

It is further configured that: the box is provided with a water temperature sensor that cooperates with a soil temperature sensor to control the opening and closing of the heating rod.

Through the above technical solution, since the temperature of the water for irrigating the plants is too high, the plants will die, so the temperature of the water in the water storage tank is detected by the water temperature sensor. When the soil temperature sensor detects that the soil temperature is too low and the water temperature sensor detects that the water temperature is lower than 20 degrees Celsius, turn on the heating rod; when the soil temperature sensor detects that the soil temperature is too low but the water temperature sensor detects that the water temperature is higher than 30 degrees Celsius, turn off the heating rod ; When the soil temperature sensor detects that the soil temperature is not low, regardless of the water temperature in the water storage tank, the heating rod is turned off.

In summary, the beneficial effects of the utility model are: the soil moisture sensor is set to detect the soil moisture, and the control valve is used to realize automatic judgment whether irrigation is needed; the soil temperature sensor is set to detect that the soil temperature is low, and the irrigation water is heated by the heating rod to make Plants get the right growing environment.
