Description

Technical Field

[0001] This utility model belongs to the field of agricultural frost prevention technology, specifically relating to an intelligent spraying device for preventing fruit tree flowers from freezing. Background Technology

[0002] Fruit trees are extremely sensitive to low temperatures during their spring flowering period, especially when temperatures plummet below freezing, easily damaging the stigma of the pistil. The stigma is a crucial part for pollination and fruit development; frost damage leads to pollination failure, consequently affecting fruit formation and development. Statistics show that a severe frost can reduce orchard yields by more than 30%, or even cause total crop failure. For fruit growers, this not only results in direct economic losses but can also impact the long-term growth of fruit trees and the sustainable development of orchards. Therefore, effectively preventing fruit tree flowers from freezing has become an important research direction in agricultural technology.

[0003] Currently, common frost protection methods in orchards mainly include smoke fumigation, mulching, and heating. Smoke fumigation involves burning straw or similar materials to generate smoke, which forms an insulating layer to slow heat loss from the ground. However, this method has limited effectiveness and produces large amounts of smoke, polluting the environment and potentially causing fires. Mulching involves covering fruit trees with insulating materials to reduce heat loss, but this method is cumbersome, costly, and unsuitable for large-scale orchards. Heating raises the orchard temperature by burning fuel or using electric heating equipment; this method is energy-intensive, costly, and may pollute the environment. These traditional methods generally suffer from low efficiency, high energy consumption, complex operation, and environmental pollution, making it difficult to meet the needs of modern orchards for efficient and environmentally friendly frost protection.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-3 The present invention provides the following technical solution: an intelligent spraying device for preventing fruit tree flowers from freezing, comprising: a deep well pump 1, a booster pump 2, a pipeline 3, a spraying system 4, a meteorological data acquisition system 5, a control system 6, and an erection device 7.

[0031] Deep well pump 1, with its inlet directly connected to groundwater, is used to extract groundwater at a temperature of 12℃ to 15℃ from a depth of 30 to 50 meters underground.

[0032] Booster pump 2 is located at the connection between the main pipeline 31 and each branch pipeline 32, and pressurizes the spray water in each branch pipeline 32.

[0033] Pipeline 3 includes main pipeline 31, branch pipeline 32, and nozzles, wherein;

[0034] The main pipeline, connected to the deep well pump 1, is used to transport water pumped from underground by the deep well pump 1 to the branch pipelines. A solenoid valve 8 is installed at the connection point between the main pipeline and the deep well pump 1.

[0035] Branch pipes are provided in several parts, consisting of risers and horizontal pipes. The risers are connected to the booster pump 2 to deliver water to the horizontal pipes, and the risers and horizontal pipes are connected by elbows.

[0036] Horizontal tubes include two types:

[0037] A device with several nozzles installed on both sides and the bottom of the pipe wall for spraying above the canopy of fruit trees;

[0038] Another method involves installing several nozzles on both sides of the pipe wall for spraying the middle of the fruit tree canopy.

[0039] The nozzle, mounted on a horizontal pipe, is used to atomize water and spray it onto the canopy of the fruit trees;

[0040] The meteorological data acquisition system 5 is installed between the rows of fruit trees by means of poles. The meteorological data acquisition system 5 also includes a data temperature acquisition module and a wind acquisition module, which are used to collect real-time air temperature and wind data near the canopy of the fruit trees.

[0041] The meteorological data acquisition system 5 is installed near the canopy of the fruit trees and transmits the real-time air temperature and wind speed data near the canopy of the fruit trees to the control system 6 in real time.

[0042] The control system 6 controls the operation of the deep well pump 1 and the solenoid valve 8. During operation, when the temperature and wind speed data reach their lower limits, the control system automatically opens the deep well pump 1 to extract groundwater. The solenoid valve 8 automatically opens, delivering the groundwater to the main pipeline 31, branch pipeline 32, and sprinklers. The sprinklers then atomize the water and spray it onto the canopy of the fruit trees. The control system 6 includes a data processing module and a control module. The data processing module receives and analyzes the data transmitted from the meteorological data acquisition system 5, while the control module controls the opening and closing of the deep well pump 1 and the solenoid valve 8 based on the analysis results.

[0043] The erection device 7 consists of columns and steel wires. The top of the column is connected to the steel wire. The column has two heights: one above the tree canopy for installing a horizontal spray pipe for spraying flowers from above the canopy; the other at the middle of the canopy for installing a horizontal spray pipe for spraying flowers from the middle of the canopy. The base of the column is buried at the edge of the tree. The top of the column is connected to the steel wire, which is fixedly connected to the horizontal pipe for securing it. The columns of erection device 7 are made of high-strength metal, and the steel wires are made of stainless steel. The columns of erection device 7 are height-adjustable, and the base of the column is fixed to the ground via a pre-embedded flange.

[0044] In this implementation, in the orchard, firstly, the erection device 7 is installed. Posts of appropriate height are selected based on the tree height and fixed in place. Steel wires are connected and secured to horizontal pipes, ensuring the horizontal pipes are stably positioned above or in the middle of the tree canopy. Next, the deep well pump 1 is placed 30-50 meters underground, with its inlet connected to groundwater. The main pipe 31 is connected to the deep well pump 1, and a solenoid valve 8 is installed at the connection point. The riser of the branch pipe 32 is connected to the booster pump 2. The horizontal pipe is connected to the riser via an elbow, and a nozzle is installed on the horizontal pipe. Simultaneously, the meteorological data acquisition system 5 is installed near the tree canopy between rows of fruit trees using poles, ensuring accurate collection of air temperature and wind speed data. Finally, the meteorological data acquisition system 5 is connected to the control system 6, which in turn is connected to the deep well pump 1 and the solenoid valve 8, completing the installation and wiring of the entire device.

[0045] The meteorological data acquisition system 5 collects real-time air temperature and wind speed data near the fruit tree canopy and stores it in the data storage module. Simultaneously, it transmits the collected data to the data processing module of the control system 6. The data processing module analyzes the received data in real time to determine whether the temperature and wind speed have reached preset lower limits.

[0046] When the data processing module analyzes and determines that the temperature and wind speed data have reached the lower limit, the control module automatically controls the deep well pump 1 to start, extracting groundwater from a depth of 30-50 meters underground. At the same time, the solenoid valve 8 automatically opens, and the groundwater is transported through the main pipe 31 to each branch pipe 32. Under the action of the booster pump 2, the spray water in each branch pipe 32 is pressurized, allowing the water to smoothly reach the horizontal pipe. Finally, the nozzles installed on the horizontal pipe atomize the water and spray it onto the canopy of the fruit trees, realizing the spraying operation to prevent the fruit trees from freezing. When the temperature and wind speed data rise back to a safe range, the control module controls the deep well pump 1 and the solenoid valve 8 to close, stopping the spraying.

[0047] These are merely examples and are not intended to limit the scope of this utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
