Description

Technical Field

[0001] This application relates to the field of irrigation machine technology, and in particular to an energy-saving sprinkler head for sprinkler irrigation machines. Background Technology

[0002] Sprinkler irrigation is an irrigation method that uses water pumps and pipeline systems or the drop of natural water sources to spray pressurized water through sprinklers (or nozzles) into the air, where it is dispersed into small droplets or forms a mist that falls onto plants and the ground.

[0003] Sprinkler irrigation, compared to traditional irrigation methods, is water-saving, labor-saving, efficient, and highly adaptable; however, it also has some limitations. Sprinkler irrigation systems require a large amount of machinery and piping materials, and the system operates at high pressure, resulting in high energy demands and increasing the burden on oil, electricity, or natural gas supplies, thus raising operating costs. Therefore, in the current international context of energy shortages and rising energy prices, addressing the high energy requirements of sprinkler irrigation systems is crucial. Furthermore, in existing technologies, irrigation nozzles are prone to freezing and clogging in cold weather, which can prevent the nozzles from discharging water properly and affect their normal operation. Summary of the Invention

[0005] This application adopts the following technical means to achieve:

[0006] An energy-saving sprinkler head for a sprinkler irrigation machine includes: a pressure-stabilizing water pipe and a sprinkler head mechanism; the sprinkler head mechanism is connected to one end of the pressure-stabilizing water pipe via a sprinkler head water pipe, and the other end of the pressure-stabilizing water pipe is connected to one end of a water supply branch pipe of the sprinkler irrigation machine, wherein an electrically controlled valve is installed on the water supply branch pipe of the sprinkler irrigation machine; the diameter of the pressure-stabilizing water pipe is larger than that of the water supply branch pipe of the sprinkler irrigation machine and the sprinkler head mechanism.

[0007] Furthermore, the nozzle mechanism includes: a filtration system, a nozzle water pipe, and a pressurizing and heating component; the filtration system is installed at the bottom of the nozzle water pipe by threads, and the filtration system includes: a connecting part and a filter screen, the external thread of the connecting part is engaged with the internal thread of the lower end of the nozzle water pipe, the filter screen is fixedly installed at the lower end of the connecting part, and the filter screen is located inside the pressure-stabilizing water pipe.

[0008] Furthermore, the pressurizing and heating component is installed inside the nozzle water pipe, and a step is provided at the upper part of the nozzle water pipe. When the connection part of the filter system is connected to the internal thread provided at the lower end of the nozzle water pipe, the pressurizing and heating component is squeezed tightly.

[0009] Furthermore, a first sealing ring is provided between the pressurizing and heating component and the upper step inside the nozzle water pipe, and a second sealing ring is provided between the pressurizing and heating component and the connection of the filtration system.

[0010] Furthermore, the pressurizing and heating component is a cylindrical component whose size is adapted to the lower end of the nozzle water pipe. The lower end of the pressurizing and heating component has a first conical hole in the center, with the bottom diameter of the first conical hole being larger than the top diameter. The upper end of the pressurizing and heating component has a second conical hole in the center, with the bottom diameter of the second conical hole being smaller than the top diameter. The first conical hole and the second conical hole are connected through a cylindrical through hole.

[0011] Furthermore, the heater is disposed within the cylindrical through-hole of the pressurized heating component.

[0012] Furthermore, a flow meter 5 is installed on the outer wall of the sprinkler head water pipe with a step to monitor the flow rate in the energy-saving sprinkler head of the sprinkler irrigation machine in real time.

[0013] Furthermore, one end of the nozzle is connected to the upper side wall of the nozzle water pipe, and multiple sets of nozzles are evenly distributed around the nozzle water pipe. Several hemispherical nozzles are evenly distributed on the other end face of the nozzle.

[0014] Furthermore, the hemispherical nozzle is provided with several evenly distributed nozzle branch pipes, the axes of which intersect at the center of the hemispherical nozzle, and the several evenly distributed nozzle branch pipes are connected to several connecting holes provided in the nozzle cross section.

[0015] Furthermore, two annular protrusions are installed at the outlet of the nozzle branch pipe, with the height of the protrusion closer to the outlet of the nozzle branch pipe being lower than the height of the inner protrusion.

[0016] A method for using an energy-saving sprinkler head for a sprinkler irrigation machine:

[0017] (1) Connect the energy-saving sprinkler head of the sprinkler to the water supply branch pipe of the sprinkler;

[0018] (2) Start the sprinkler and begin working; the flow meter monitors the flow rate in the energy-saving sprinkler head in real time; if the flow rate is normal, continue working until the sprinkler is turned off and then stopped; if the flow rate is lower than the set threshold, proceed to step (3).

[0019] (3) The heater starts working for a set time and monitors the flow rate inside the energy-saving sprinkler head of the sprinkler machine. If the flow rate is normal, the abnormal flow rate caused by icing and blockage is resolved. If the flow rate is still lower than the set threshold, the sprinkler machine is turned off, the energy-saving sprinkler head of the sprinkler machine is removed, the filter system inside the energy-saving sprinkler head of the sprinkler machine is taken out and cleaned, and the energy-saving sprinkler head of the sprinkler machine is reassembled after cleaning. Then, step (1) is executed.

[0020] This application has the following advantages

[0021] (1) The use of pressure stabilizing water pipes stabilizes the water pressure from the sprinkler irrigation machine's water supply pipes, which reduces the requirements for the sprinkler irrigation machine's water pump and can save energy; the filter screen can filter impurities in the water, prevent clogging of the sprinkler head branch pipes, and can also save energy.

[0022] (2) The pressure-boosting heating component can change the water pressure by changing the diameter and shape of the pipeline. The pressure-boosting heating component can be disassembled and replaced, which is very flexible. Replacing the pressure-boosting heating component can change the maximum irrigation range of the sprinkler head without changing the water pressure of the sprinkler machine, which can achieve a good energy-saving effect.

[0023] (3) The heater is installed in the cylindrical through hole of the pressurized heating component, which can prevent the irrigation water from freezing and clogging the nozzle by heating the irrigation water flow;

[0024] (4) By designing multiple sets of nozzles, several hemispherical nozzles and several evenly distributed nozzle branch pipes, 360-degree irrigation without dead angles can be achieved, and there is no need to set up a separate nozzle rotation device or drive the nozzle to rotate by losing part of the kinetic energy of the irrigation water, which can achieve the purpose of energy saving.

[0032] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present application are shown in the accompanying drawings, not all of them.

[0033] Figure 1 The diagram shows a schematic of an energy-saving sprinkler head used in conjunction with a sprinkler irrigation system's water supply pipe. The energy-saving sprinkler head includes: a pressure-stabilizing water pipe 3 and a sprinkler head mechanism 4. The sprinkler head mechanism 4 is connected to one end of the pressure-stabilizing water pipe 3, and the other end of the pressure-stabilizing water pipe 3 is connected to one end of a water supply branch pipe 2 of the sprinkler irrigation system. The other end of the water supply branch pipe 2 is connected to the water supply pipe 1 of the sprinkler irrigation system. The water supply branch pipe 2 and the water supply pipe 1 are fixedly connected. The pressure-stabilizing water pipe 3 is threaded to the sprinkler head mechanism 4 and the water supply branch pipe 2. The lower end of the sprinkler head water pipe 42 of the sprinkler head mechanism 4 has an external thread, and the upper end of the water supply branch pipe 2 also has an external thread. The diameter of the pressure-stabilizing water pipe 3 is larger than the diameter of the water supply branch pipe 2 and the sprinkler head water pipe 42 of the sprinkler head mechanism 4. The function of the pressure-stabilizing water pipe is to stabilize the water pressure from the water supply pipe 1 of the sprinkler irrigation system, which reduces the requirements on the sprinkler irrigation system's water pump and thus achieves energy savings. Preferably, the diameter of the pressure-stabilizing water pipe 3 is at least three times that of the sprinkler irrigation machine's water supply branch pipe 2. An electrically controlled valve is installed on the sprinkler irrigation machine's water supply branch pipe 2.

[0034] like Figure 2-4 As shown, the nozzle mechanism 4 includes: a filtration system 41, a nozzle water pipe 42, and a pressurizing and heating component 43. The filtration system 41 is threadedly installed at the bottom of the nozzle water pipe 42. The filtration system 41 includes: a connecting part and a filter screen. The external thread of the connecting part mates with the internal thread of the lower end of the nozzle water pipe 42. The filter screen is fixedly installed at the lower end of the connecting part. The filter screen can filter impurities in the water and prevent clogging of the nozzle branch pipe 471. The filter screen part of the filtration system 41 is located inside the pressure stabilizing water pipe 3.

[0035] The pressurizing and heating component 43 is disposed inside the nozzle water pipe 42. A step is provided at the upper part of the nozzle water pipe 42 to restrict the movement of the pressurizing and heating component 43 within the nozzle water pipe 42. When the connection part of the filter system 41 is connected to the internal thread provided at the lower end of the nozzle water pipe 42, it will squeeze the pressurizing and heating component 43 tightly. A first sealing ring 44 is provided between the pressurizing and heating component 43 and the step provided at the upper part of the nozzle water pipe 42, and a second sealing ring 45 is provided between the connection part of the pressurizing and heating component 43 and the filter system 41. The pressurizing and heating component 43 is a hollow cylindrical part, the size of which is adapted to the lower end of the sprinkler head water pipe 42. A first conical hole 431 is centrally located at the lower end of the pressurizing and heating component 43, with a bottom diameter larger than the top diameter. A second conical hole 433 is centrally located at the upper end of the pressurizing and heating component 43, with a bottom diameter smaller than the top diameter. The first and second conical holes 431 and 433 are connected by a cylindrical through hole 432. The pressurizing and heating component 43 can change the water pressure by altering the pipe diameter and shape. Furthermore, the pressurizing and heating component 43 is removable and replaceable, offering great flexibility. The first and second conical holes 431 and 433 can be selected with other suitable surface shapes, such as parabolic surfaces, ellipsoids, or other suitable rotating surfaces, depending on actual needs. Replacing the pressurizing and heating component 43 can change the maximum irrigation range of the sprinkler head without changing the water pressure of the irrigation machine, achieving excellent energy-saving effects. The cone angle of the first conical hole 431 is preferably 45 degrees, and the cone angle of the second conical hole is preferably 83 degrees. Experiments and simulations have verified that this cone angle condition provides the best pressure increase effect. Furthermore, preferably, the length of the first conical hole 431 is 2.5 times the length of the second conical hole 433. This is the optimal design scheme for the pressure-boosting heating component 43 under the aforementioned cone hole design. The heater 434 is installed inside the cylindrical through-hole 432 of the pressure-boosting heating component 43. The heater 434 can be a spiral heating tube, embedded in the inner wall of the cylindrical through-hole 432. The inner wall is then smoothed with a heat-conducting material to avoid affecting the flow of irrigation water. The power supply line of the heater 434 is led out through the body of the pressure-boosting heating component 43 and powered through the power supply contact terminals provided on the nozzle water pipe 42. The presence of the first sealing ring 44 and the second sealing ring 45 ensures power supply safety. On the water outlet side of the pressure-boosting heating component 43, a flow meter 5 is installed on the outer wall of the nozzle water pipe 42, which has a stepped section. The flow meter 5 can monitor the flow data within the nozzle mechanism 4 in real time.

[0036] like Figure 1-3 As shown in Figure 5-7, the nozzle 46 is connected to and communicates with the upper side wall of the nozzle water pipe 42. Multiple sets of nozzles 46 are evenly distributed around the nozzle water pipe 42. (Reference) Figure 1-3It can be seen that there are four sets of nozzles 46, which are horizontally arranged. One end of the nozzle 46 is connected to the upper side wall of the nozzle water pipe 42, and several hemispherical nozzles 47 are evenly distributed on the other end face of the nozzle 46. Figure 3 For example, the end face of the nozzle 46 is circular, with a hemispherical nozzle 47 at its center. Four other hemispherical nozzles 47 are evenly distributed on a circle centered on the central hemispherical nozzle 47. One end of the nozzle 46 is connected to the nozzle water pipe 42, and the other end has several connecting holes 472 for connecting to several hemispherical nozzles 47. Several evenly distributed nozzle branch pipes 471 are provided on the hemispherical nozzles 47, with their axes intersecting at the center of the hemispherical nozzle 47. These branch pipes 471 are connected to the connecting holes 472. Through the design of multiple sets of nozzles 46, several hemispherical nozzles 47, and several evenly distributed nozzle branch pipes 471, 360-degree irrigation without dead angles can be achieved, eliminating the need for a separate nozzle rotation device or driving the nozzles by sacrificing some of the kinetic energy of the irrigation water, thus achieving energy conservation.

[0037] To achieve the atomized form of the water droplets and further increase the irrigation range, such as Figure 6-7 As shown, two annular protrusions are provided at the outlet of each sprinkler branch pipe 471. The height of the protrusion closer to the outlet of the sprinkler branch pipe 471 is lower than that of the inner protrusion. The two adjacent protrusions can simultaneously increase the irrigation range and enhance water droplet atomization. The inner protrusion, which is taller, mainly increases the irrigation range, while the protrusion closer to the outlet of the sprinkler branch pipe 471 is used to achieve water droplet atomization. Preferably, the cross-section of the protrusion is as shown in the figure. Figure 6 The diagram shows a triangle. The advantage of a triangular cross-section is better water droplet atomization; the protruding corners can better break up the droplets. The protruding cross-section is as follows: Figure 7 As shown, the cross-section is arc-shaped. The advantage of an arc-shaped cross-section is that it can achieve water droplet atomization while taking into account the irrigation range. The arc-shaped protrusion can break up the droplets while having little impact on the water ejection speed, thus achieving a larger irrigation range.

[0038] A method for using an energy-saving sprinkler head for a sprinkler irrigation machine:

[0039] (1) Connect the energy-saving sprinkler head of the sprinkler to the water supply branch pipe 2 of the sprinkler;

[0040] (2) Start the sprinkler and begin working; the flow meter 5 monitors the flow rate of the energy-saving sprinkler head in real time; if the flow rate is normal, continue working until the sprinkler is turned off and then stopped; if the flow rate is lower than the set threshold, proceed to step (3).

[0041] (3) Heater 434 starts working for a set time and monitors the flow rate value inside the energy-saving sprinkler head of the sprinkler machine. If the flow rate value is normal, the abnormal flow rate caused by icing and blockage is resolved. If the flow rate value is still lower than the set threshold, the sprinkler machine is turned off, the energy-saving sprinkler head of the sprinkler machine is removed, the filter system 41 inside the energy-saving sprinkler head of the sprinkler machine is taken out for cleaning, and the energy-saving sprinkler head of the sprinkler machine is reassembled after cleaning. Step (1) is executed.
