Description

Technical Field

[0001] This utility model relates to the field of sprinkler irrigation technology, specifically to a rotary sprinkler irrigation unit for water conservancy irrigation. Background Technology

[0002] Rotary sprinkler irrigation units for water conservancy irrigation are mechanized irrigation equipment that uses power to drive the sprinkler head to rotate around a vertical axis, spraying pressurized water through the nozzles into the air and dispersing it into fine water droplets, which are then evenly sprayed onto irrigated areas such as farmland. They are characterized by a large irrigation range, high uniformity, and water and energy saving. The rotation speed, spray radius, and other parameters can be adjusted according to crop type, soil conditions, and irrigation needs. They are widely used in large-area irrigation scenarios such as field crops, orchards, and grasslands, and can effectively improve irrigation efficiency and quality while reducing labor costs.

[0003] Existing rotary sprinkler irrigation units for water conservancy have a problem: before use in cold weather, the water remaining in the sprinkler heads freezes and expands at low temperatures. This causes the sprinkler heads and internal pipes, valves, and other components to crack or deform due to excessive pressure. This not only affects the normal operation of the sprinkler heads but may also cause the entire sprinkler irrigation system to malfunction, significantly increasing maintenance costs. At the same time, frozen sprinkler heads cannot spray water normally, resulting in a severe decrease in irrigation uniformity. Crops cannot be effectively irrigated, which in turn affects crop growth and may even lead to reduced yields. In addition, frequent repairs and replacements of sprinkler heads due to freezing damage will delay farming, reduce irrigation efficiency, and bring many inconveniences and economic losses to agricultural production. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a rotary sprinkler irrigation unit for water conservancy irrigation, which can effectively solve the problem that in the existing technology, the water remaining in the sprinkler head before use in cold weather will freeze and expand at low temperature, causing the sprinkler head and internal pipes, valves and other components to be damaged by excessive pressure, such as cracking and deformation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a rotary sprinkler irrigation unit for water conservancy irrigation, including:

[0007] The mounting frame has a defrosting mechanism at its bottom. The bottom of the defrosting mechanism has a linear array of multiple heating ring mechanisms and sprinkler mechanisms, with the sprinkler mechanisms located inside the heating ring mechanisms.

[0008] Furthermore, a controller is installed on the side of the mounting frame, and the defrosting mechanism includes a mounting box fixedly connected to the bottom of the mounting frame. Multiple partition plates are fixedly connected in a linear array inside the mounting box, and the partition plates divide the interior of the mounting box into multiple heating zones. Each heating zone has a pair of first interconnecting holes on both sides, and multiple second interconnecting holes are arranged in a ring array at the bottom of each heating zone.

[0009] Furthermore, the upper surface of the mounting box is provided with a pair of solar panels and a liquid distribution assembly, and the solar panels are electrically connected to the controller. The liquid distribution assembly includes a three-way valve fixedly connected to the upper surface of the mounting box. One input end of the three-way valve is fixedly connected to a delivery pipe, and the other end of the delivery pipe is connected to the irrigation storage device. Both output ends of the three-way valve are fixedly connected to a diversion pipe. The diversion pipe has one input end and multiple output ends, and the input end is connected to the output end of the three-way valve.

[0010] Furthermore, protective covers corresponding to the second interconnection holes are fixedly connected to both sides of the mounting box. A detection barrel is fixedly connected inside each of the protective covers, and a temperature detector is installed inside the detection barrel. The temperature detector is electrically connected to the controller. The output end of the three-way valve passes through the protective cover and is connected to the input end of the detection barrel. Multiple heat absorption plates are fixedly connected in a ring array at the center of the outer circumference of the detection barrel. A connecting pipe is fixedly connected to the output end of the detection barrel.

[0011] Furthermore, each of the heating zones is equipped with a directional heating mechanism, which includes a heater fixedly connected to the top of the heating zone.

The detection tank monitors the temperature in real time and determines the heating conditions, ensuring that heating is only initiated when necessary. This ensures the nozzle functions normally, avoids energy waste, and controls the heating temperature to prevent secondary damage caused by excessive heat. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0034] The present invention will be further described below with reference to the embodiments.

[0035] Example: Refer to Figures 1 to 9 The mounting frame 1 has a defrosting mechanism 2 at its bottom. The bottom of the defrosting mechanism 2 has a linear array of multiple heating ring mechanisms 3 and irrigation sprinkler mechanisms 4, with the irrigation sprinkler mechanisms 4 located inside the heating ring mechanisms 3.

[0036] The mounting bracket 1 is used to connect the defrosting mechanism 2, the heating mechanism 3, the sprinkler mechanism 4 and the irrigation equipment. The defrosting mechanism 2 is used to heat the sprinkler mechanism 4, thereby preventing the water remaining in the sprinkler mechanism 4 from freezing inside the sprinkler mechanism 4 due to cold air, which would affect the use of the sprinkler mechanism 4 and cause damage to the sprinkler mechanism 4. The heating mechanism 3 is used to guide and directionally transfer heat, thereby concentrating the heat on the sprinkler mechanism 4.

[0037] Reference Figure 3 , Figure 5The mounting frame 1 has a controller installed on its side. The defrosting mechanism 2 includes a mounting box 21 fixedly connected to the bottom of the mounting frame 1. Multiple partition plates 212 are fixedly connected in a linear array inside the mounting box 21. The partition plates 212 divide the interior of the mounting box 21 into multiple heating zones. Each heating zone has a pair of first interconnecting holes 211 on both sides. Each heating zone has multiple second interconnecting holes 213 arranged in a ring array at the bottom of its inner side.

[0038] The partition plate 212 is used to divide the installation box 21 into multiple independent heating zones. The heat in the heating zone is applied to the detection tank 25 and then guided to the sprinkler mechanism 4 by the heating ring mechanism 3 through the first interconnection hole 211 and the second interconnection hole 213 in the heating zone.

[0039] Reference Figure 1 , Figure 3 The upper surface of the mounting box 21 is provided with a pair of solar panels 22 and a liquid distribution assembly 23. The solar panels 22 are electrically connected to the controller. The liquid distribution assembly 23 includes a three-way valve 231 fixedly connected to the upper surface of the mounting box 21. One input end of the three-way valve 231 is fixedly connected to a delivery pipe 233. The other end of the delivery pipe 233 is connected to the irrigation storage device. Both output ends of the three-way valve 231 are fixedly connected to a diversion pipe 232. The diversion pipe 232 has one input end and multiple output ends, and the input end is connected to the output end of the three-way valve 231.

[0040] The solar panel 22 provides current to the subsequent directional heating mechanism 26 and the detection tank 25, while the water is delivered to the three-way valve 231 through the delivery pipe 233. The delivery pipe 233 further diverts the water, which then acts on the sprinkler mechanism 4.

[0041] Reference Figures 3 to 5 Both sides of the mounting box 21 are fixedly connected with protective covers 24 corresponding to the second interconnection hole 213. Each protective cover 24 is fixedly connected with a detection barrel 25, and a temperature detector is installed inside the detection barrel 25. The temperature detector is electrically connected to the controller. The output end of the three-way valve 231 passes through the protective cover 24 and is connected to the input end of the detection barrel 25. Multiple heat absorption plates 251 are fixedly connected in a ring array at the center of the outer circumference of the detection barrel 25. The output end of the detection barrel 25 is fixedly connected to a connecting pipe 252.

[0042] The detection tank 25 can receive water transferred from the three-way valve 231 to the irrigation mechanism 4 through the diversion pipe 232 and fill it. The temperature detector inside the detection tank 25 is used to detect changes in water content, which indirectly indicates the temperature of the residual water in the irrigation mechanism 4. The heat absorption plate 251 is used to absorb the heat released into the protective cover 24 through the first interconnection hole 211. Since the detection tank 25 is located inside the protective cover 24, the heat will pass through the sealed environment formed by the protective cover 24 and then through the heat absorption plate 251 to heat the water inside the detection tank 25.

[0043] Reference Figure 4 , Figure 6 Each heating zone is equipped with a directional heating mechanism 26. The directional heating mechanism 26 includes a heater 261 fixedly connected to the top of the heating zone. The heater 261 is electrically connected to the controller. A heat dissipation plate 262 is fixedly connected to the other side of the heater 261. A second heat-conducting plate 264 corresponding to the first interconnection hole 211 is fixedly connected to both sides of the heat dissipation plate 262. A first heat-conducting plate 263 is fixedly connected to both sides of the heat dissipation plate 262, and the heat dissipation plate 262 is located between the second heat-conducting plate 264 and the first heat-conducting plate 263.

[0044] The heater 261 in the directional heating mechanism 26 provides heat to the detection tank 25 and the spraying mechanism 4, while the heat dissipation plate 262 is used to uniformize the temperature generated by the heater 261. The first heat-conducting plate 263 guides the heat to the ring heating mechanism 3, and the second heat-conducting plate 264 guides the heat to the detection tank 25.

[0045] Reference Figure 2 , Figures 8 to 9 The heating mechanism 3 corresponds to the second interconnection hole 213. The heating mechanism 3 includes a directional tube 31 fixedly connected to the bottom of the mounting box 21, and the second interconnection hole 213 is located inside the directional tube 31.

[0046] The inner circumferential surface of the directional tube 31 is linearly arrayed with multiple annular plates 33 whose width gradually increases from top to bottom, and through holes 32 are provided on both sides of the outer circumferential surface of the directional tube 31.

[0047] The sprinkler mechanism 4 includes a fixed plate 41 fixedly connected to the bottom of the mounting box 21 inside the directional pipe 31. A rotating nozzle 42 is fixedly connected to the other side of the fixed plate 41. The other end of the connecting pipe 252 passes through the through hole 32 and is connected to the input end of the rotating nozzle 42.

[0048] By utilizing the connection between the directional tube 31 and the second interconnection hole 213 in the annular heating mechanism 3, the temperature of the heating zone enters the directional tube 31. The annular plate 33 in the directional tube 31 can gradually disperse the temperature transferred to the directional tube 31 and act on the sprinkler irrigation mechanism 4 to achieve heating of the sprinkler irrigation mechanism.

[0049] The working principle of this utility model is as follows:

[0050] First, fix the mounting bracket 1 on the irrigation equipment (such as a mobile irrigation vehicle), connect the controller power supply, and the solar component 22 (such as a solar panel) absorbs light energy and converts it into electrical energy to power the controller, heater 261 and other components, while charging the storage battery for backup. After the controller is started, it first detects the ambient temperature (by the temperature detector in the detection tank 25). If the temperature is lower than the set threshold (such as close to the freezing point), the defrosting process is triggered (the directional heating mechanism 26 is started).

[0051] As the heater 261 of the directional heating mechanism 26 begins to heat up, the heat is evenly distributed through the heat dissipation plate 262, while the first heat-conducting plate 263 guides the heat to the directional tube 31 of the ring heating mechanism 3, and enters the interior of the directional tube 31 through the second interconnection hole 213. The second heat-conducting plate 264 conducts the heat through the first interconnection hole 211 to the detection barrel 25 inside the protective cover 24, heating the water inside the barrel.

[0052] Special Note: The annular plate 33 (width increasing from top to bottom) inside the directional tube 31 guides heat downwards layer by layer, uniformly heating the outside of the rotating nozzle 42 and preventing residual water inside from freezing. During irrigation, the controller opens the three-way valve 231, and water (or other irrigation liquid) in the irrigation storage enters the three-way valve 231 through the delivery pipe 233, and is distributed to each detection tank 25 through the diversion pipe 232. The temperature detector in the detection tank 25 monitors the liquid temperature in real time. If the temperature is too low, the heater 261 continues to heat until the liquid temperature reaches the standard (to prevent the low-temperature liquid from aggravating the freezing of the nozzle). The heated liquid enters the rotating nozzle 42 through the connecting pipe 252 and the through hole 32. When the liquid enters the rotating nozzle 42, it drives the nozzle to rotate, spraying the liquid into fine water droplets for uniform irrigation. The directional tube 31 of the heating mechanism 3 continues to conduct heat to maintain the nozzle temperature above the freezing point, preventing water from freezing and clogging inside or at the outlet of the nozzle during irrigation.

[0053] During sprinkler irrigation or when not in use, if the detection tank 25 detects that the liquid temperature is close to the freezing point, the controller automatically extends the working time of the heater 261. Heat is continuously replenished through the first heat-conducting plate 263 and the second heat-conducting plate 264 to ensure that the liquid in the nozzles and pipes does not freeze. Meanwhile, the heat-absorbing plate 251 absorbs heat from the protective cover 24 to further heat the liquid in the detection tank 25, forming a closed-loop temperature control system.

[0054] If the ambient temperature drops suddenly or the irrigation is suspended, the controller controls the three-way valve 231 to switch to the "drain" mode, returning the residual liquid in the nozzle and pipeline to the memory. At the same time, the heater 261 is activated to dry and heat the nozzle, preventing residual moisture from freezing and expanding, which could damage the components.

[0055] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
