Description

Technical Field

[0001] This utility model relates to the field of greenhouse sprinkler irrigation technology, specifically to a gas-liquid integrated sprinkler irrigation system for greenhouses. Technical Background

[0002] As is well known, greenhouses are widely used in agricultural production. In northern my country, due to the climate, vegetables cannot be grown in the natural environment during winter. Therefore, the most common way to grow vegetables is to use greenhouses. Since there is no rain in northern winters, it is necessary to irrigate the vegetables in the greenhouses.

[0003] Currently, when irrigating crops in greenhouses, water is mostly drawn manually or by pumps to the soil surface inside the greenhouse. The water then flows through ditches on the ground until it covers the entire greenhouse floor. However, this irrigation method is not only time-consuming and wasteful of water resources, but also prone to uneven irrigation due to varying ditch depths, which can negatively impact vegetable yields, thus limiting its usability.

[0004] To address the aforementioned issues, Chinese Utility Model Patent Application No. 202321970464.6 discloses a water-saving irrigation device for greenhouses. Its features include: an inlet pipe to supply irrigation water to a storage tank; a pump, connecting pipe, and transmission pipe working together to supply the irrigation water to a distribution chamber; and an opening regulating valve to spray the irrigation water through atomizing nozzles, thus irrigating crops within the greenhouse. Simultaneously, a drive motor drives a reciprocating mechanism, enabling the atomizing nozzles to uniformly irrigate the crops within the greenhouse. The overall structure is relatively simple, facilitating irrigation of crops within the greenhouse, and is more water-efficient and provides more uniform irrigation compared to existing irrigation methods.

[0005] However, the existing technology has the following technical problems: In order to ensure suitable crop growth conditions, it is necessary to comprehensively regulate the greenhouse environment, rather than simply regulating a certain environmental factor. However, the device can only provide irrigation for crops, which is a single function and has low practicality. Utility Model Content

The remote switch component is used for remote control by the operator to open or close the outlet end of the remote switch component, so that the CO2 in the gas generating and storing component is sprayed out or stopped from spraying out through a plurality of gas outlets on the second delivery pipe.

Detailed Implementation

[0029] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0030] Please refer to Figures 1 to 9This utility model provides a greenhouse gas-liquid integrated sprinkler irrigation system 10, including a liquid sprinkler irrigation device 12, a gas sprinkler irrigation device 13, and a sprinkler irrigation pipeline mounting bracket 14;

[0031] The liquid sprinkler irrigation device 12 is connected to a first delivery pipe 123, which is equipped with several atomizing nozzles 1231 for spraying water, fertilizer or pesticides to irrigate, fertilize or kill insects and fungi on crops; the gas sprinkler irrigation device 13 is connected to a second delivery pipe 134, which is equipped with several air outlets for spraying CO2 gas to supplement CO2 on crops; the sprinkler irrigation pipeline mounting frame 14 is erected above the crops, and the first delivery pipe 123 and the second delivery pipe 134 are fixedly installed on the sprinkler irrigation pipeline mounting frame 14.

[0032] In this embodiment, the greenhouse gas-liquid integrated sprinkler irrigation system 10 is mainly applicable to greenhouse 11. Its core function is to collaboratively supply liquid substances to crops and supplement gaseous substances. The droplets sprayed from the atomizing nozzle 1231 can remain suspended in the air for a long time, increasing the contact area and contact time with crop leaves. This not only promotes the absorption of foliar fertilizer but also avoids the impact on crop seedlings or soil structure caused by excessively large droplets falling directly. It also helps to uniformly regulate the humidity in the greenhouse. The parallel integrated arrangement of the first delivery pipe 123 and the second delivery pipe 134 allows sprinkler irrigation and gas fertilizer supplementation to be completed synchronously or sequentially in a single operation, greatly improving the efficiency and convenience of comprehensive greenhouse environmental control.

[0033] Furthermore, the sprinkler pipe mounting bracket 14 includes a fixed bracket 141 and a movable bracket 142. The fixed bracket 141 is mounted above the crop via support columns. The movable bracket 142 is vertically and flexibly mounted on the fixed bracket 141 via a lifting assembly, and the first delivery pipe 123 and the second delivery pipe 134 are fixed to the movable bracket 142 by pipe clamps.

[0034] In this embodiment, both the fixed frame 141 and the movable frame 142 are made of hollow square steel. The fixed frame 141 is erected on the ground, and the movable frame 142 is fitted onto the fixed frame 141 and can move up and down. The lifting component is an electric push rod with a stroke of 1.5 meters and a rated thrust of 500 Newtons. It receives control signals through a wireless receiver. Its fixed end is set on the fixed frame 141, and its telescopic end is connected to the movable frame 142. This allows the first delivery pipe 123 and the second delivery pipe 134 to be flexibly adjusted according to the crop growth height, always maintaining the optimal operating distance above the canopy. This not only ensures the effective coverage and sedimentation of atomized droplets and carbon dioxide gas, avoiding diffusion loss due to excessive distance or leaf damage that may be caused by excessive distance, but also significantly improves resource utilization and irrigation uniformity.

[0035] In another embodiment, the fixed frame 141 can also be fixedly installed on the steel frame of the greenhouse 11, and the movable frame 142 is fitted on the fixed frame 141. The movable frame 142 can be raised and lowered by the lifting component, which reduces the land occupation in the greenhouse and improves the space utilization rate.

[0036] Furthermore, the liquid irrigation device 12 also includes a liquid holding and stirring assembly 121 and a pumping assembly 122. The liquid holding and stirring assembly 121 is used to hold water, fertilizer or pesticides and stir them evenly to ensure uniform mixing and prevent sedimentation. The inlet end of the pumping assembly 122 is connected to the liquid holding and stirring assembly 121, and the outlet end is connected to the first delivery pipe 123 to draw water, fertilizer or pesticides from the liquid holding and stirring assembly 121 and atomize and spray them out.

[0037] In this embodiment, the pumping assembly 122 includes a plunger pump 1221 and a mobile trolley 1222. The plunger pump 1221 is a corrosion-resistant plunger pump with a rated flow rate of 1.5 cubic meters per hour and a rated head of 30 meters to meet the irrigation needs of most greenhouses. It has a pressure stabilizing function, which can provide a stable liquid source with a stable pressure for the atomizing nozzles 1231, ensuring atomization uniformity. The plunger pump 1221 is fixedly installed on the mobile trolley 1222, which facilitates flexible scheduling between different greenhouses 11, realizing the cyclic irrigation operation of one set of equipment for multiple greenhouses. The continuous stirring of the liquid holding and stirring assembly 121 and the stable delivery of the pumping assembly 122 work together to fundamentally avoid the fluctuation of irrigation liquid concentration caused by uneven mixing or sedimentation of water, fertilizer or pesticides, ensuring that the nutrient or pesticide concentration that crop leaves or roots can contact is consistent, effectively improving the overall planting uniformity and yield quality.

[0038] Of course, it is worth noting that the atomizing nozzle 1231 of the liquid irrigation device 12 is adjustable, and the spraying intensity and range can be adjusted according to the type and growth stage of the crop, thereby further improving the accuracy and efficiency of irrigation.

[0039] Furthermore, the liquid holding and stirring assembly 121 includes a holding tank 1211 and a stirring cover 1213. The holding tank 1211 is used to hold fertilizer or pesticides. The bottom of the holding tank 1211 is provided with a suction pipe connection port 1212 for connecting to the inlet end of the pumping assembly 122. The stirring cover 1213 includes a cover body 12131 and a stirring mechanism 12132. The stirring mechanism 12132 is fixedly installed on the cover body 12131 for stirring after the holding tank 1211 is covered, thereby reducing splashing of fertilizer or pesticide solution.

[0040] In this embodiment, the stirring mechanism 12132 is a paddle driven by a low-speed, high-torque motor with a rated power of 90W and a rotation speed of 50-100 rpm, to ensure that the liquid in the tank is gently and thoroughly mixed, avoiding excessive foaming or splashing. Through the connection between the bottom suction pipe connection port 1212 and the pumping assembly 122, the well-stirred water, fertilizer, or pesticide can be efficiently absorbed and transported.

[0041] Furthermore, it is worth noting that the mixing mechanism 12132 can also integrate a timer control module, which can preset the mixing program so that it can start at a time before irrigation and during irrigation intervals, thereby maintaining a uniform mixing state of the liquid during irrigation and fundamentally avoiding the problem of inconsistent concentration of irrigation liquid caused by the settling of solid components due to the pausing of mixing.

[0042] Furthermore, the gas spraying device 13 also includes a gas generating and storing component 131, a pressure display component 132, and a remote switch component 133. The outlet end of the gas generating and storing component 131 is sequentially connected to the pressure display component 132 and the remote switch component 133. The outlet end of the remote switch component 133 is connected to the second delivery pipe 134. The gas generating and storing component 131 is used to generate CO2 and store it in a pressure vessel. The pressure display component 132 is used to display the pressure value in the pressure vessel. The remote switch component 133 is used to enable the operator to remotely control and open the outlet end of the remote switch component 133 so that the CO2 in the gas generating and storing component 131 is sprayed out from a plurality of gas outlets on the second delivery pipe 134.

[0043] In this embodiment, the gas generation and storage component 131 can specifically be a CO2 cylinder or a CO2 generator, which provides a gas source for the system. The pressure display component 132 is a pressure gauge installed on the gas source outlet pipeline to visually display the real-time pressure in the cylinder or storage tank, providing a basis for judging the remaining gas volume. The remote switch component 133 can be a normally closed solenoid valve and is connected to the greenhouse control system via a wireless communication module, thereby receiving switch signals from the control terminal (such as a PLC or a dedicated remote controller), realizing remote start-stop control without the need for personnel to be physically present, greatly improving the convenience and response speed of operation.

[0044] Furthermore, the greenhouse gas-liquid integrated sprinkler irrigation system 10 also includes a temperature and humidity monitoring device 15. The temperature and humidity monitoring device 15 includes a display module 151 and a temperature and humidity sensor 152. The temperature and humidity sensor 152 is fixedly installed on the sprinkler pipeline mounting bracket 14 to monitor the temperature and humidity in the greenhouse 11. The display module 151 is fixedly installed in the greenhouse 11 and electrically connected to the temperature and humidity sensor 152 to display the temperature and humidity in the greenhouse 11.

[0045] Furthermore, temperature and humidity sensors 152 are respectively installed at three different positions (low, medium, and high) on the sprinkler pipe mounting bracket 14 to monitor the temperature and humidity at different heights.

[0046] In this embodiment, the display module 151 is a 7-inch LED display screen, which is wall-mounted and fixed to the wall of the greenhouse 11. The temperature and humidity sensors 152 are high-precision digital sensors, connected to the LED display screen via signal lines. The three temperature and humidity sensors 152 are precisely positioned at three different locations on the sprinkler pipe mounting bracket 14: low (0.5 meters from the ground), medium (crop canopy height), and high (2.5 meters from the ground). The LED display screen can simultaneously and clearly display temperature and humidity values ​​from three different heights in real time, and can be expanded to support the display of real-time curves, historical extreme values, or set threshold alarm information. This achieves three-dimensional environmental monitoring of the greenhouse interior space. Operators can intuitively obtain microclimate data of the crop root zone, canopy, and upper space from the entrance without entering the depths of the crop area, providing direct and layered data for the precise control of liquid irrigation, gas application, and airflow agitation devices.

[0047] Of course, it is worth noting that a CO2 concentration sensor can also be added to monitor the CO2 concentration in the greenhouse in real time, so as to determine whether CO2 supplementation is needed in the greenhouse based on the monitoring results.

[0048] Furthermore, the greenhouse gas-liquid integrated sprinkler irrigation system 10 also includes an airflow agitation device 16, which is fixedly installed on the sprinkler pipeline mounting bracket 14 to generate forced convection in the greenhouse to agitate the airflow and improve air circulation.

[0049] Furthermore, the airflow agitation device 16 includes a fan 161 and an airflow adjustment component 162. The fan 161 is fixedly installed above the sprinkler pipe mounting bracket 14, and the airflow adjustment component 162 is located at the air outlet of the fan 161 to adjust the airflow direction of the fan 161.

[0050] Furthermore, the wind direction adjustment assembly 162 includes an adjustment frame 1621, guide vanes 1622 and a drive assembly 1623. The guide vanes 1622 are rotatably mounted in the adjustment frame 1621 at equal intervals. The drive assembly 1623 is connected to the guide vanes 1622 in a transmission connection to drive the guide vanes 1622 to rotate synchronously, thereby adjusting the wind direction of the fan 161.

[0051] In this embodiment, the fan 161 is an axial flow fan with a diameter of 400 mm and a rated air volume of 3000 cubic meters per hour. The drive assembly 1623 includes a servo motor 16231 and a connecting rod 16232 connected to it. Driven by the servo motor 16231, all guide vanes 1622 are synchronously deflected via the connecting rod 16232 to control the angle of airflow. This not only strongly promotes the uniform diffusion of carbon dioxide from the gas irrigation device 13 and atomized droplets from the liquid irrigation device 12 in the greenhouse space, eliminating local dead zones and improving the utilization rate of gas fertilizer and pesticide fertilizer, but also effectively promotes the balance of temperature and humidity in the entire space. By enhancing air circulation, it accelerates leaf surface water evaporation, fundamentally reducing the risk of diseases caused by high humidity and stuffy environment, and creating a more uniform and healthy growth environment for crops.

[0052] When implementing this utility model, the staff first needs to check various environmental parameters inside the greenhouse 11, such as temperature, humidity, and CO2 concentration, to ensure they are in the optimal state for crop growth. Then, according to the type and growth stage of the crop, the atomizing nozzles 1231 of the liquid irrigation device 12 are adjusted to determine the spraying intensity and range. Next, an appropriate amount of water, fertilizer, or pesticide is placed in the container, the stirring cap 1213 is tightened, and the stirring mechanism 12132 is started to stir the water, fertilizer, or pesticide to ensure thorough mixing and prevent settling. At the same time, the gas is operated... The air-liquid integrated irrigation system 10 controls the release of CO2 through a remote switch component 133 to meet the CO2 supplementation needs of crops. During the irrigation process, the temperature and humidity monitoring device 15 monitors and displays the environmental data inside the greenhouse in real time so as to make timely adjustments. After the irrigation is completed, the airflow agitator 16 is activated to enhance the air circulation inside the greenhouse and promote the healthy growth of crops. Through this series of operations, the greenhouse air-liquid integrated irrigation system 10 can efficiently complete the comprehensive regulation of the greenhouse environment, ensure that crops grow in a suitable environment, and thus improve crop yield and quality.

[0053] The modules or units in the device of this utility model embodiment can be merged, divided, and deleted according to actual needs. The above-disclosed embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of this utility model. Those skilled in the art can understand that implementing all or part of the processes of the above embodiments and making equivalent changes according to the claims of this utility model still fall within the scope of this utility model.
