DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0020] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. Example
[0021] Reference Figure 1-Figure 5 , which is the first embodiment of the present invention, provides a regulating mechanism 200 for an energy-saving irrigation method for a water conservancy project. The flow rate of the nozzle is regulated by this embodiment. The regulating mechanism 200 can be applied to scenes that require precise control of the irrigation flow rate, such as farmland irrigation, landscaping, greenhouse planting, etc. Through the regulating mechanism 200, the flow rate of the nozzle can be flexibly adjusted according to actual needs to achieve the purpose of saving water and energy.
[0022] Specifically, the regulating mechanism 200 is installed on the water pipe 100, and the regulating mechanism 200 includes a movable kit 210 and a third sleeve 220. The movable kit 210 is rotatably installed on the water pipe 100, and an adjusting piece 230 is installed in the movable kit 210. The third sleeve 220 has an irrigation port 221, and the third sleeve 220 is slidably installed on the movable kit 210 through the adjusting piece 230.
[0023] Preferably, the adjusting member 230 includes a movable rod 231, a sealing ring 232, a sealing block 233 and a sealing plate 234. The sealing ring 232 is fixedly installed in the first sleeve 211, and the sealing plate 234 is fixedly installed in the third sleeve 220. One end of the movable rod 231 is fixedly connected to the sealing plate 234. A connecting bracket 204 is fixedly installed in the open end of the first sleeve 211 away from the second sleeve 212. One end of the movable rod 231 away from the sealing plate 234 passes through the connecting bracket 204 to the outside of the water pipe 100. The sealing block 233 is rotatably installed on the movable rod 231 and can be tightly pressed against the sealing ring 232.
[0024] Preferably, the movable rod 231 includes a fourth sleeve 205 and a push rod 206, an adjusting nut 207 is rotatably installed on the water pipe 100, the fourth sleeve 205 is threadedly installed in the adjusting nut 207, the push rod 206 is slidably installed in the fourth sleeve 205 and a second spring 208 is fixedly connected to the inner bottom surface of the fourth sleeve 205.
[0025] Furthermore, when the device is in use, the water pipe 100 is the main channel for conveying water in the entire irrigation system. Before irrigation, multiple groups of water pipes 100 can be connected end to end, and then the end of the high-pressure water inlet is connected to the water pipe 100. The connected water pipe 100 can be buried deep in the area required for irrigation of the water conservancy project to complete the equipment preinstallation. On the one hand, when supplying water, the high-pressure water flow can flow at a high speed inside the water pipe 100 and lift the sealing block 233, so that the sealing block 233 is separated from the sealing ring 232, and the water flows into the movable kit 210 and the third sleeve 220 through the gap between the sealing block 233 and the sealing ring 232. The third sleeve 220 is lifted by the movable rod 231 and moves up on the movable kit 210 to expose the irrigation port 221. To achieve the purpose of irrigation; on the other hand, before burying the water pipe 100, the position of the fourth sleeve 205 can be changed by rotating the adjusting nut 207, thereby adjusting the extension and contraction degree of the push rod 206, and controlling the up and down movement distance of the third sleeve 220, thereby realizing the adjustment of the initial flow rate, meeting different irrigation needs, avoiding unnecessary waste of water resources, and reducing energy consumption. When the water flow pressure decreases, a first spring 235 is movably installed on the movable rod 231, and the two ends of the first spring 235 are respectively fixed to the sealing block 233 and the connecting bracket 204. The first spring 235 will help the sealing block 233 to reset and re-contact with the sealing ring 232 to form a sealed state, reducing the maintenance workload and increasing the reliability and ease of use of the system.
[0026] Specifically, the movable kit 210 includes a first sleeve 211 and a second sleeve 212. The first sleeve 211 is fixedly installed with a first impeller 240 at one end located in the water pipe 100. The first sleeve 211 is provided with a wave groove 201 on its end surface located outside the water pipe 100. The second sleeve 212 is coaxially sleeved on the first sleeve 211. A sliding pin 202 matching the wave groove 201 is fixedly installed on the inner wall of the second sleeve 212. A straight groove 203 is provided on the outer wall of the second sleeve 212. A guide rod 110 is fixedly installed on the water pipe 100, and the guide rod 110 is matched with the straight groove 203.
[0027] Furthermore, in the absence of water flow, the first sleeve 211 and the second sleeve 212 are in a stationary state, and the third sleeve 220 is located at a preset position, so that the opening of the irrigation port 221 is fixed when it is opened. When water flows through the water pipe 100, the water flow impacts the first impeller 240, causing the first sleeve 211 to rotate, and the wave groove 201 rotates with the first sleeve 211, driving the sliding pin 202 in the second sleeve 212 to slide along the wave groove 201. The guide rod 110 constrains the rotation of the second sleeve 212, so that the second sleeve 212 moves back and forth along the axial direction. , driving the third sleeve 220 to move up and down reciprocatingly. On the one hand, it effectively prevents water from directly impacting the soil, reduces soil erosion and water accumulation, and thus avoids over-irrigation. On the other hand, the movement of the third sleeve 220 in the soil can slightly loosen the soil, help improve the soil structure, increase soil aeration, and reduce soil compaction. Water can penetrate into the soil, take away salt, and reduce soil salinization. Irrigation equipment that is partially or completely buried in the soil can reduce the loss of water due to evaporation in the air, ensuring that more water can reach the roots of plants, thereby improving irrigation efficiency.
[0028] Specifically, the second sleeve 212 has an embedding groove 209 on one side close to the third sleeve 220, and a baffle plate 250 is slidably installed in the embedding groove 209. A third spring 260 is fixedly connected between the baffle plate 250 and the bottom surface of the embedding groove 209. A push rod 270 is fixedly installed on the side of the baffle plate 250 away from the third spring 260. The push rod 270 is slidably connected to the sealing plate 234, and the space formed by the sealing plate 234 and the third sleeve 220 is filled with paraffin.
[0029] Preferably, a second impeller 280 is fixedly mounted on the push rod 206 , and the second impeller 280 is located in the water pipe 100 .
[0030] Furthermore, the third sleeve 220 is made of metal and has strong heat conductivity that can be transferred to paraffin. In the absence of water flow, the sealing block 233 is in close contact with the sealing ring 232, and the baffle 250 is also in the initial position under the action of the paraffin and the third spring 260. At this time, the irrigation port 221 is in a closed or preset opening state. When water flows through the water pipe 100, the water flow impacts the second impeller 280, causing the push rod 206 to rotate. The push rod 206 drives the third sleeve 220 to rotate on the second sleeve 212, which can evenly distribute the water flow to the surroundings, avoiding the problem of excessive wetness or excessive dryness in some areas caused by fixed nozzles; on the other hand, paraffin is filled between the sealing plate 234 and the third sleeve 220, and can expand under different temperature conditions and push the top rod 270 to change the position of the baffle 250, thereby changing the opening size of the irrigation port 221 and adjusting the flow rate of the nozzle. Example
[0031] Reference Figure 2-Figure 5 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: this embodiment provides an oxygen supply mechanism 300, through which the formation of soil aggregate structure is promoted.
[0032] Specifically, the oxygen supply mechanism 300 is arranged in the movable kit 210, including a fixing ring 310, a connecting rod 320, an airbag 330 and an output tube 340, the connecting rod 320 can slide along the circumferential direction of the fixing ring 310, the airbag 330 is sleeved on the connecting rod 320, and the output tube 340 is fixedly connected to the airbag 330.
[0033] Preferably, the output pipe 340 is a hard pipe. When the third sleeve 220 is lifted up by the movable rod 231 and moves upward on the second sleeve 212, the pipe mouth of the output pipe 340 is exposed. The airbag 330 has an air inlet pipe 331. Both the air inlet pipe 331 and the output pipe 340 are equipped with a one-way valve. The airbag 330 is filled with oxygen through the air inlet pipe 331. The one-way valve on the air inlet pipe 331 ensures that oxygen can only enter the airbag 330 but cannot flow out in the opposite direction. When the airbag 330 is filled with oxygen, the oxygen drives the output pipe 340 to reciprocately squeeze the airbag 330 through the reciprocating second sleeve 212, so that the oxygen in the airbag 330 is released into the soil through the output pipe 340. The one-way valve on the output pipe 340 ensures that oxygen can only be released outward but cannot flow into the airbag 330 in the opposite direction. A good oxygen supply helps decompose organic matter in the soil, generates heat, helps regulate soil temperature, and provides a suitable growth environment for crops.
[0034] It should be noted that the gas inlet of the air inlet pipe 331 is located above the soil.
[0035] Preferably, the output tube 340 includes a fixed portion 341 and a movable portion 342, the movable portion 342 is sleeved on the fixed portion 341, the surface of the movable portion 342 has a first tooth groove 301, the inner wall of the third sleeve 220 is provided with a second tooth groove 222, and a gear 350 is rotatably installed on the second sleeve 212, and the gear 350 is meshed and connected with the first tooth groove 301 and the second tooth groove 222.
[0036] Furthermore, when the third sleeve 220 rotates, the second tooth groove 222 on its inner wall meshes with the gear 350, driving the gear 350 to rotate. The rotation of the gear 350 drives the movable part 342 of the output pipe 340 to slide along the fixed part 341 through the first tooth groove 301, which will change the position and length of the output pipe 340, thereby adjusting the release position and range of oxygen. The second sleeve 212 is fixedly installed with a surrounding plate 213, so that a sealed cavity is formed between the surrounding plate 213 and the inner wall of the second sleeve 212 to reduce leakage. The movable part 342 is slidably connected to the surrounding plate 213, which can effectively provide oxygen to the soil, improve soil conditions, and promote the healthy growth of crops.
[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
