Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery and equipment, and specifically relates to a photovoltaic-driven circular sprinkler irrigation system. Background Technology

[0002] With the increasing severity of global water scarcity, water-saving irrigation has become a trend in agricultural irrigation in arid regions. Circular sprinkler irrigation systems, with their advantages of water conservation, increased yield, strong adaptability, high mechanization, and high labor efficiency, are widely used in large-scale, intensive agricultural production. However, in practical applications, circular sprinkler irrigation systems still face some pressing problems. Firstly, because the system rotates around a central axis while irrigating, the irrigated area is circular. Irrigating square plots results in missed areas at the four corners; in square plots, this means 23% of the area is missed, and in rectangular plots, the missed area exceeds 30%, leading to a waste of land resources. Secondly, while electrically driven circular sprinkler irrigation systems are the mainstream driving method covering many major grain-producing areas, the lack of infrastructure in remote areas makes it difficult to guarantee a reliable power supply. Solar energy, as a clean and renewable energy source, using photovoltaic power generation technology, can provide energy for the stable operation of circular sprinkler irrigation systems, achieving the dual benefits of water-saving irrigation and energy conservation and emission reduction. Utility Model Content

[0003] In view of the above-mentioned shortcomings in the prior art, the present invention provides a photovoltaic-driven circular sprinkler irrigation system that solves the problems of land resource waste caused by irrigation blind spots at the corners of circular sprinkler irrigation sites and insufficient power supply in remote areas.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows: a photovoltaic-driven circular sprinkler irrigation system, comprising a steel structure, an irrigation subsystem, and a solar power supply system. The steel structure is connected to the irrigation subsystem, and the solar power supply system is connected to both the steel structure and the irrigation subsystem. The solar power supply system is equipped with a solar panel, which is installed in the central area of ​​the circular sprinkler irrigation system where spraying is missed.

[0005] Furthermore: the steel structural components include a base and a main control box, with the main control box fixed on the base.

[0006] Furthermore, the irrigation subsystem includes interconnected water pumps and motors, with the motors also connected to solar panels.

[0007] Furthermore, solar power systems also include inverters, controllers, and energy storage devices;

[0009] Furthermore, the solar panels and controllers are both installed in the central area of ​​the leaks in the square-arranged circular sprinkler system.

[0020] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All inventions utilizing the concept of this utility model are protected.

[0021] like Figure 1 As shown, in one embodiment of this utility model, a photovoltaic-driven circular sprinkler irrigation system includes a steel structure, an irrigation subsystem, and a solar power supply system. The steel structure is connected to the irrigation subsystem, and the solar power supply system is connected to both the steel structure and the irrigation subsystem. The solar power supply system is equipped with a solar panel 3, which is installed in the central area of ​​the circular sprinkler irrigation system.

[0022] The steel structure is also equipped with a drive motor to control the walking drive of the circular sprinkler irrigation machine, an irrigation subsystem to control the water spraying and irrigation of the circular sprinkler irrigation machine, and a solar power system to collect and store solar energy to provide power for the operation of the system.

[0023] In this embodiment, the circular sprinkler irrigation machines are arranged in a square pattern in the field. The solar panel 3 is arranged in a square pattern with four circular sprinkler irrigation machines as a group. A photovoltaic array is installed in the central area of ​​the four circular sprinkler irrigation machines that are missed, and the generated electricity powers them. When there is sufficient sunshine, the electricity generated by the photovoltaic effect is directly used by the four surrounding circular sprinkler irrigation machines. The excess energy is stored in the energy storage device 6 through the controller 5 and used by the circular sprinkler irrigation machines on cloudy days or at night.

[0024] The steel structure includes a base and a main control box 1. The main control box 1 is fixed on the base. The main control box 1 is used to receive signals, process them and issue instructions to control the circular sprinkler. The main control box 1 is powered by solar energy generated by the solar panel 3.

[0025] The irrigation subsystem includes interconnected water pumps 2 and motors, with the motors also connected to solar panels 3.

[0026] In this embodiment, the motor is placed on each span tower and is powered directly by the solar panel 3 or by the energy storage device 6.

[0027] The solar power system also includes an inverter 4, a controller 5, and an energy storage device 6, which is used to store excess electrical energy.

[0028] The inverter 4 is installed vertically and placed on a ground support at a set distance from the ground. One end of the inverter 4 is connected to the energy storage device 6 or the controller 5, and the other end of the inverter 4 is connected to the main control box 1 and the water pump 2.

[0029] In this embodiment, the solar power system mainly provides electrical energy for the circular sprinkler machine's walking drive and irrigation. The controller 5 is used to protect the energy storage device 6 from overcharging or over-discharging, and at the same time provides a stable DC voltage source to the inverter 4.

[0030] Both the solar panel 3 and the controller 5 are installed in the central area of ​​the leaking water of the square-arranged circular sprinkler.

[0031] In this embodiment, the controller 5 is installed in the middle of the central area of ​​the circular sprinkler machine with a square arrangement. The solar panels 3 are hollowed out, raised and arranged regularly to maximize the transmission of sunlight. The entire photovoltaic array is connected to the controller interface. At the same time, shade-tolerant crops or root crops can be planted at its bottom to make full use of the land.

[0032] Both the controller 5 and the energy storage device 6 are placed inside the distribution box to protect the equipment, and the controller 5 and the energy storage device 6 are separated by a certain distance to dissipate heat.

[0033] The specific working process of this utility model is as follows:

[0034] Solar panels 3 are installed in the square blank area between the four circular sprinkler irrigation machines, with no other obstructions, to maximize the light energy absorption efficiency. The solar panels 3 charge the energy storage device 6 via the controller 5, prioritizing direct power supply on sunny days and storing any surplus. Simultaneously, the main control box 1 receives signals to start the circular sprinkler irrigation machines. The four circular sprinkler irrigation machines are located at the four corners of the square, and by adjusting the nozzle angle and range, they cover the central area (the blind spot of traditional circular sprinkler irrigation). The control motor directly drives the water pump 2 for irrigation. The irrigation radius is designed to be √2 / 2 times the side length of the square, ensuring overlapping irrigation without dead zones.

[0035] To ensure that the electricity generated by the solar power system can provide a reliable power supply for the normal operation of the circular sprinkler irrigation unit, the following specific example is given, taking Beijing as an example.

[0036] Arrange the circular sprinkler systems in a square pattern in the field, with each system irrigating an area of ​​7 square meters. Figure 2 As shown, the circular sprinkler irrigation machine consists of four spans (54.5m each) and a cantilever (20.1m), with a total length of 238.1m and a total system flow rate of 63m³. 3 The machine has a working power (excluding pump power) of 3.7KW, a working voltage of 380V, and a pump flow rate of 63m³ / h. Each tower is equipped with a 0.55KW motor.3 / h, head is 60m, motor power is 13KW.

[0037] Because the irrigation area of ​​a circular sprinkler is circular, there will be some missed areas on square plots. (Example: Missed area of ​​a circular sprinkler, e.g., 8) Figure 2 As shown, Figure 2 The circular sprinkler shown has a central missed area of ​​48,664.49 m². 2 To prevent irrigation water splashing from affecting the solar power generation system, the square area of ​​solar panel installation area 9 is as follows: Figure 3 As shown, the solar panel installation location 10 is as follows. Figure 4 As shown, the solar panels are arranged in a high, perforated pattern, with an tilt angle consistent with Beijing's latitude and a due south azimuth. The area of ​​this region is 38907.56 m². 2 Solar panels with dimensions of 2278×1134×35mm and a peak power of 550W were selected. Considering the need for sufficient spacing between the solar panels to ensure sunlight transmission and facilitate future maintenance and management, 30% of the area was reserved, allowing for the installation of 10,542 solar panels. Therefore, in one peak hour, these solar panels can generate 5798.1KW of electricity. Beijing's peak sunshine duration is 4.3 hours. Considering factors such as charging efficiency, dust, and degradation, the system efficiency is taken as 0.8, resulting in a daily power generation demand of 19945.46KW. If four circular sprinkler irrigation machines operate simultaneously, this power generation far exceeds the machine's requirements. To prevent excess power waste, surplus electricity can be stored in an energy storage device for use by the circular sprinkler irrigation machines at night or on cloudy days. Since the power generation from installing solar panels in the entire unused area far exceeds the power requirements of the circular sprinkler irrigation machines, it is advisable to consider grid-connecting the solar power generation to recover benefits; alternatively, only a suitable range of solar panels can be installed to ensure the normal operation of the circular sprinkler irrigation machines. If we only consider the power requirements of the circular sprinkler irrigation machines, assuming four machines operate for four hours, and taking into account the power losses of the inverter, controller, and energy storage equipment, calculations show that approximately 277 solar panels are needed. With a 30% allowance for spacing between the solar panels, the total floor space required for the solar panels would be 1022.23 m². 2 This accounts for approximately 2.1% of the total open space area.

[0038] The beneficial effects of this utility model are as follows: This utility model provides a photovoltaic-driven circular sprinkler irrigation system. Through the coordinated operation of multiple circular sprinklers and the installation of solar panels 3 in areas where spraying is missed, and by integrating higher density solar panels 3, it improves the problem of land resource waste caused by the operation of existing circular sprinklers. The installation of solar panels makes full use of land resources.

[0039] Compared with existing circular sprinkler irrigation machines, the solar-powered multiple circular sprinkler irrigation units of this invention use electricity generated by solar panels 3, rather than supplied by the power grid. This can save energy, reduce emissions, reduce carbon emissions, and achieve sustainable development.

[0040] This invention can solve the problem of insufficient energy, is applicable to remote areas or areas lacking electricity, and reduces irrigation costs.
