Description

Technical Field

[0001] This application relates to the technical field of drip irrigation devices, and particularly to an anti-blocking ground-inserted drip irrigation device. Background Art

[0002] The drip irrigation device is the most critical component in the drip irrigation system. Existing drip irrigation devices are usually tubular structures, with their bottoms closed and provided with water dripping holes. The bottoms of the drip irrigation devices are inserted into the ground for local irrigation of crops. Due to the shortage of water resources, highly sediment-laden water and slightly saline water are also used for irrigation. However, these water bodies contain a large amount of impurities such as suspended solids and microorganisms, which usually adhere and accumulate on the inner wall of the drip irrigation device, affecting the flow capacity of the drip irrigation device. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide an anti-blocking ground-inserted drip irrigation device to solve the problem that impurities in water adhere and accumulate on the inner wall of the drip irrigation device, affecting the flow capacity of the drip irrigation device.

[0004] Based on the above purpose, this application provides an anti-blocking ground-inserted drip irrigation device, including:

[0005] A first drip irrigation pipe for drip irrigation of crops;

[0006] A water distribution structure arranged in the first drip irrigation pipe, including a plurality of arc-shaped structures connected to the inner wall of the first drip irrigation pipe. The plurality of arc-shaped structures are sequentially arranged along the height direction of the first drip irrigation pipe to guide part of the water flow to form a swirling water flow in the first drip irrigation pipe; a direct current hole is provided through the plurality of arc-shaped structures in the height direction of the water distribution structure to guide part of the water flow to form a direct water flow in the first drip irrigation pipe;

[0007] The swirling water flow and the direct water flow form a turbulent flow between at least some adjacent arc-shaped structures.

[0008] Optionally, the water distribution structure is a continuous spiral structure, and the plurality of arc-shaped structures are used to form the spiral structure.

[0009] Optionally, the first drip irrigation pipe includes a connected first pipe body section and a first tip section. The first pipe body section is detachably connected to the first tip section, and the first tip section is provided with first water dripping holes.

[0010] Optionally, a filtering component is arranged in the first pipe body section. The filtering component includes a filter screen cylinder and an adsorbent. The filter screen cylinder is located at one end of the first pipe body section close to the first tip section, and the adsorbent is located inside the filter screen cylinder.

[0011] Optionally, the water diversion structure is located inside the first pipe section and on the side of the filter cartridge away from the first tip section. A limiting member is provided between the filter cartridge and the water diversion structure to limit the upward floating of the filter cartridge.

[0012] Optionally, it further includes a second drip irrigation pipe sleeved outside the first drip irrigation pipe. The second drip irrigation pipe includes a connected second pipe section and a second tip section. The second pipe section is sleeved outside the first pipe section, and the second tip section is sleeved outside the first tip section. Second water dripping holes are provided on the second tip section. The first drip irrigation pipe is rotatably connected to the second drip irrigation pipe so that the first water dripping holes and the second water dripping holes are staggered or communicated.

[0013] Optionally, at least two rows of the first water dripping holes are provided along the height direction of the first tip section. Each row of the first water dripping holes is evenly arranged along the circumferential direction of the first tip section and gradually decreases in the direction pointing to the tip of the first tip section; at least two rows of the second water dripping holes are provided along the direction of the tip of the second tip section. Each row of the second water dripping holes is evenly arranged along the circumferential direction of the second tip section and gradually decreases in the direction pointing to the tip of the second tip section; a first positioning member is provided at the top of the first pipe section, and at least two second positioning members are provided on the outer wall of the second pipe section. When the first positioning member is connected to one of the second positioning members, one row of the first water dripping holes is communicated with one row of the second water dripping holes, and the remaining rows of the first water dripping holes are staggered with the second water dripping holes.

[0014] Optionally, the first positioning member and the second positioning member are magnetically connected.

[0015] Optionally, a water inlet is provided at the top end of the first pipe section, and the top end of the first pipe section is located inside the drip irrigation tape so that the water inlet is communicated with the drip irrigation tape.

[0016] Optionally, a snap ring is provided at the top end of the first pipe section, and the snap ring is located inside the drip irrigation tape to prevent the first pipe section from detaching from the drip irrigation tape.

[0017] As can be seen from the above, an anti-blocking ground-inserted drip irrigation device provided by the present application includes a first drip irrigation pipe and a water distribution structure. The water distribution structure includes an arc surface structure connected to the inner wall of the first drip irrigation pipe. A plurality of the arc surface structures are arranged in sequence along the height direction of the first drip irrigation pipe to guide part of the water flow to form a swirling water flow in the first drip irrigation pipe, so as to increase the flow velocity of the water flow, reduce the accumulation of impurities such as sand grains and microorganisms in the first drip irrigation pipe. In addition, due to the centrifugal force generated when the water flow flows on the arc surface structure, the swirling water flow tends to flow away from the center of the spiral structure, so the swirling water flow is more likely to scour the inner wall of the first drip irrigation pipe, further reducing the accumulation of impurities such as sand grains and microorganisms in the first drip irrigation pipe, thus ensuring the flow capacity of the first drip irrigation pipe. When the water flow with a relatively large pressure surges into the top of the water distribution structure, the water flow is divided into two parts: one part forms a swirling water flow along the arc surface structure, and the other part flows linearly in the straight flow channel to become a straight water flow. Since the swirling water flow is subjected to a relatively small centrifugal force when it initially flows on the arc surface structure, the swirling water flow is more likely to converge with the straight water flow. The two water flows meet at the upper part of the water distribution structure and form a turbulent flow under their mutual action. The turbulent flow can avoid the pressure drop caused by the excessively high local flow velocity of the water flow (such as avoiding cavitation phenomenon), so as to maintain the high efficiency of the water flow in a certain range. At the same time, it can disturb the fluid, wash away the sediment on the inner wall of the first drip irrigation pipe, reduce scaling, and thus improve the service life of the drip irrigation device.

Detailed implementation manners

[0026] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the following further elaborates on the present application in detail with reference to specific embodiments and the accompanying drawings.

[0027] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should have the ordinary meanings understood by those with ordinary skills in the field to which the present application belongs. The "first", "second" and similar terms used in the embodiments of the present application do not indicate any order, quantity or importance, but are only used to distinguish different components. The terms such as "including" or "comprising" mean that the elements or objects appearing before this word cover the elements or objects listed after this word and their equivalents, without excluding other elements or objects. The terms such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The terms such as "upper", "lower", "left" and "right" are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0028] Based on the background described above, in modern agricultural irrigation systems, drip irrigation technology has become a key means to ensure the water supply for crop growth in many regions due to its characteristics of high efficiency and water conservation. As the core component of the drip irrigation system, the performance of the drip irrigation emitter directly affects the operation effectiveness of the entire drip irrigation system. Currently, common drip irrigation emitters are mostly designed in a tubular structure, with a closed bottom and carefully arranged water dripping holes. During actual application, the bottom of the drip irrigation emitter is accurately inserted into the ground, and water is stably delivered slowly to the area around the crop roots through the water dripping holes, achieving local precise irrigation. This not only effectively avoids water waste but also ensures that the crop roots obtain sufficient water to promote their healthy growth.

[0029] However, the global water resources situation is becoming increasingly severe, and available freshwater resources are becoming increasingly scarce. In this predicament, water sources with low utilization rates in the past, such as high-sediment water and brackish water, have begun to be introduced into agricultural irrigation in large quantities. High-sediment water often comes from water sources in river flood seasons and areas with severe soil erosion, which contain a large amount of sediment particles and various suspended substances; brackish water is widely found in coastal areas and inland saline-alkali areas. In addition to containing high salt content, it may also contain a variety of microorganisms and mineral impurities.

[0030] When these special water sources are used for drip irrigation, the suspended matter in the high-sand water is easily deposited and adhered to the inner wall of the drip irrigator under the influence of the water flow, due to the relatively narrow water flow channel inside the drip irrigator. At the same time, microorganisms in the slightly salty water will rapidly multiply on the inner wall of the drip irrigator under the appropriate temperature and humidity environment, interweaving with the suspended matter to form a layer of dirt accumulation that is difficult to clean. As time goes by, this layer of dirt continues to thicken, resulting in a significant reduction in the effective flow area of the drip irrigator and a significant increase in water flow resistance. The originally smooth water flow is hindered, and the flow capacity of the drip irrigator is seriously reduced, making it impossible to deliver water to crops at the predetermined flow rate and pressure. This will not only affect the normal growth and development of crops, resulting in reduced yields, but also may cause uneven growth of crops in farmland due to uneven irrigation, further exacerbating the loss of agricultural production.

[0031] In order to solve the above problems, the present application provides an anti-blocking ground-inserted drip irrigator.

[0032] The following is combined with Figures 1-6 The embodiments of the present application will be described in detail.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, an anti-blocking ground-inserted drip irrigation device comprises:

[0034] A first drip irrigation pipe 1, used for drip irrigation of crops;

[0035] The water-dividing structure 2 is arranged in the first drip irrigation pipe 1, and includes a plurality of arc structures 21 connected to the inner wall of the first drip irrigation pipe 1. The plurality of arc structures 21 are arranged in sequence along the height direction of the first drip irrigation pipe 1 to guide part of the water flow to form a swirling water flow in the first drip irrigation pipe 1; the plurality of arc structures 21 are penetrated with straight flow holes 22 in the height direction of the water-dividing structure 2 to guide part of the water flow to form a straight flow in the first drip irrigation pipe 1;

[0036] The swirling water flow and the straight water flow form turbulent flow between at least some adjacent cambered surface structures 21 .

[0037] In addition, the water diversion structure 2 is a continuous spiral structure, and a plurality of the arc surface structures 21 are used to form the spiral structure.

[0038] Specifically, the bottom of the first drip irrigation pipe 1 is buried underground to drip irrigate the roots of crops. The arc surface structure 21 is smoothly arranged to reduce the water flow resistance and increase the water flow speed. The material of the arc surface structure 21 can be selected from plastics or metal alloys that are corrosion-resistant and wear-resistant, such as: epoxy resin plastic, stainless steel, etc., to ensure stability and durability under long-term use. A plurality of the arc surface structures 21 are sequentially arranged along the height direction of the first drip irrigation pipe 1 to guide part of the water flow to form a swirling water flow in the first drip irrigation pipe 1. A plurality of the arc surface structures 21 are used to form the spiral structure. The spiral structure can increase the flow rate of the water flow and reduce the accumulation of impurities such as sand particles and microorganisms in the first drip irrigation pipe 1. In addition, due to the centrifugal force generated when the water flow flows on the spiral structure, the swirling water flow tends to flow away from the position of the direct current hole 22, making it easier for the swirling water flow to wash the inner wall of the first drip irrigation pipe 1, further reducing the accumulation of impurities such as sand particles and microorganisms in the first drip irrigation pipe 1, thereby ensuring the flow capacity of the first drip irrigation pipe 1. The direct current hole 22 is arranged at the center of the arc surface structure 21 to make the direct water flow form a central direct water flow, which is convenient for intersecting with the swirling water flow to form a turbulent flow. When the water flow with a relatively large pressure surges into the top of the water diversion structure 2, the water flow is divided into two parts: one part forms a swirling water flow along the arc surface structure 21, and the other part flows linearly in the direct current hole 22 to become a direct water flow. Since the centrifugal force acting on the swirling water flow is relatively small when it initially flows on the spiral structure, the swirling water flow is more likely to converge with the direct water flow. The two water flows meet at the top of the water diversion structure 2 and interact to form a turbulent flow. The turbulent flow can avoid the pressure drop caused by the excessive local flow rate of the water flow (such as avoiding cavitation), thereby maintaining the high efficiency of the water flow in a certain range. At the same time, it can disturb the fluid, wash away the sediment on the inner wall of the first drip irrigation pipe 1, reduce scaling, and extend the service life of the drip irrigation device.

[0039] In some embodiments, as Figure 1 and Figure 2 shown, the first drip irrigation pipe 1 includes a connected first pipe body section 11 and a first tip section 12. The first pipe body section 11 is detachably connected to the first tip section 12, and a first water dripping hole 121 is provided on the first tip section 12.

[0040] Specifically, the first pipe body section 11 is threadedly connected to the first tip section 12 to facilitate the separation of the first tip section 12 from the first pipe body section 11, thereby facilitating the removal of debris inside the first pipe body section 11 and the first tip section 12 and preventing it from affecting the outflow of water from the first water dripping holes 121. The first pipe body section 11 and the first tip section 12 can be made of corrosion-resistant and wear-resistant plastics or metal alloys, such as epoxy resin plastics, stainless steel, etc., to ensure stability and durability under long-term use.

[0041] In this embodiment, the first pipe body section 11 is detachably connected to the first tip section 12, facilitating the cleaning of debris inside the first pipe body section 11 and the first tip section 12, so that the water flow inside the first drip irrigation pipe 1 can flow out smoothly from the first water dripping holes 121.

[0042] In some embodiments, as Figure 1 and Figure 2 shown, a filtering assembly 3 is provided inside the first pipe body section 11. The filtering assembly 3 includes a filter mesh cylinder 31 and an adsorbent. The filter mesh cylinder 31 is located at one end of the first pipe body section 11 close to the first tip section 12, and the adsorbent is located inside the filter mesh cylinder 31.

[0043] In addition, the water distribution structure 2 is located inside the first pipe body section 11 and on the side of the filter mesh cylinder 31 away from the first tip section 12. A limiting member 4 is provided between the filter mesh cylinder 31 and the water distribution structure 2 to limit the upward floating of the filter mesh cylinder 31.

[0044] Specifically, the filter mesh cylinder 31, as the main part of the filtering assembly 3, is made of corrosion-resistant and wear-resistant stainless steel or special plastics to ensure stability under long-term use. The adsorbent is located inside the filter mesh cylinder 31 and can be selected from activated carbon, resin, or other materials with adsorption ability, such as ceramic particles. The adsorbent can adsorb harmful substances, odors, and pigments in the water, further purifying the water quality and ensuring the irrigation water quality of the drip irrigation system. To prevent the filter mesh cylinder 31 from floating or moving under the action of water flow, a limiting member 4 is provided between the filter mesh cylinder 31 and the water distribution structure 2. The limiting member 4 can be a clamping block or other limiting devices to ensure that the filter mesh cylinder 31 maintains a stable position during the operation of the drip irrigation system.

[0045] In this embodiment, the filter mesh cylinder 31 is used to hold the adsorbent. The filter mesh cylinder 31 can block large-particle impurities in the water body, and the adsorbent is used to adsorb small-particle impurities and harmful organic substances in the water body. The filtering assembly 3 cleans the water body through physical and chemical actions, enabling the water flow to flow out smoothly from the first water dripping holes 121 while reducing the harm of harmful substances in the water body to crops. In addition, the filter mesh cylinder 31 has the function of buffering the water body. After the water flow passes through the filter mesh cylinder 31, it infiltrates downward by gravity, greatly reducing the impact on the soil and avoiding damaging the soil aggregate structure to the greatest extent, ensuring the air permeability of the soil.

[0046] In some embodiments, such as Figure 1 and Figure 2 shown, the top of the first pipe section 11 is provided with a water inlet 111, and the top of the first pipe section 11 is located inside the drip irrigation tape so that the water inlet 111 communicates with the drip irrigation tape.

[0047] In addition, a snap ring 112 is provided at the top of the first pipe section 11, and the snap ring 112 is located inside the drip irrigation tape to prevent the first pipe section 11 from detaching from the drip irrigation tape.

[0048] Specifically, a filter screen or sieve plate is provided at the water inlet 111 to further filter the water quality entering the drip irrigation device and prevent impurities from entering the first drip irrigation pipe 1. The drip irrigation tape is provided with a connection hole for the first drip irrigation pipe 1 to enter. The snap ring 112 can be made of elastic rubber material to block the gap in the connection hole and prevent the drip irrigation tape from leaking water.

[0049] In this embodiment, through the direct connection between the water inlet 111 and the drip irrigation tape and the fixing effect of the snap ring 112, the connection stability between the first pipe section 11 and the drip irrigation tape is effectively improved, and the first drip irrigation pipe 1 is prevented from falling off or loosening due to water flow impact or external force.

[0050] In some embodiments, such as Figure 4 and Figure 5 shown, an anti-blocking ground-inserted drip irrigation device further includes a second drip irrigation pipe 5 sleeved outside the first drip irrigation pipe 1. The second drip irrigation pipe 5 includes a connected second pipe section 51 and a second tip section 52. The second pipe section 51 is sleeved outside the first pipe section 11, and the second tip section 52 is sleeved outside the first tip section 12. The second tip section 52 is provided with second water dripping holes 521. The first drip irrigation pipe 1 is rotatably connected to the second drip irrigation pipe 5 so that the first water dripping holes and the second water dripping holes 521 are staggered or communicated.

[0051] Specifically, the first pipe section 11 fits with the second pipe section 51, and the two can rotate relative to each other. The first tip section 12 fits with the second tip section 52, and the two can rotate relative to each other, avoiding water entering between the first drip irrigation pipe 1 and the second drip irrigation pipe 5 and affecting the water dripping irrigation of crops.

[0052] In this embodiment, the first drip irrigation pipe 1 rotates relative to the second drip irrigation pipe 5, and the staggered or communicated state of the first water dripping holes 121 and the second water dripping holes 521 can be flexibly adjusted, so as to flexibly control the water flow rate of the drip irrigation device to adapt to the irrigation requirements of different crops and soil conditions, thereby improving the irrigation efficiency and water utilization rate of the drip irrigation device.

[0053] In some embodiments, such as Figure 4 、Figure 5 and Figure 6 As shown, at least two rows of the second water dripping holes 121 are arranged along the height direction of the first tip segment 12. Each row of the second water dripping holes 121 is evenly arranged along the circumferential direction of the first tip segment 12 and gradually decreases in the direction pointing to the tip of the first tip segment 12; at least two rows of the second water dripping holes 521 are arranged along the direction of the tip of the second tip segment 52. Each row of the second water dripping holes 521 is evenly arranged along the circumferential direction of the second tip segment 52 and gradually decreases in the direction pointing to the tip of the second tip segment 52; a first positioning member 6 is provided at the top of the first pipe body segment 11, and at least two second positioning members 61 are provided on the outer wall of the second pipe body segment 51. When the first positioning member 6 is connected to one of the second positioning members 61, one row of the first water dripping holes 121 is communicated with one row of the second water dripping holes 521, and the first water dripping holes 121 of the remaining rows are staggered from the second water dripping holes 521.

[0054] Specifically, the first water dripping holes 121 are arranged in N rows (N≥2) along the direction pointing to the tip of the first tip segment 12. Each row of the first water dripping holes 121 is evenly arranged along the circumferential direction of the first tip segment 12, and the number of the first water dripping holes 121 in different rows gradually decreases in the direction of the tip of the first tip segment 12; the second water dripping holes 521 are arranged in N rows (N≥2) along the direction pointing to the tip of the second tip segment 52. Each row of the second water dripping holes 521 is evenly arranged along the circumferential direction of the second tip segment 52, and the number of the second water dripping holes 521 in different rows gradually decreases in the direction of the tip of the second tip segment 52, and the number of the first water dripping holes 121 in the Nth row is the same as that of the second water dripping holes 521 in the Nth row, so as to realize the communication between the first water dripping holes 121 in the Nth row and the second water dripping holes 521 in the Nth row by rotating the first drip irrigation pipe 1, and the first water dripping holes 121 and the second water dripping holes 521 in the remaining same rows are staggered. N (N≥2) second positioning members 61 are provided on the outer wall of the second pipe body segment 51. The N second positioning members 61 respectively correspond to the communication states of the first water dripping holes 121 and the second water dripping holes 521 from the 1st row to the Nth row one by one. The first drip irrigation pipe 1 drives the first positioning member 6 to rotate so that the first positioning member 6 is connected to the Nth second positioning member 61, thereby enabling the first water dripping holes 121 in the Nth row and the second water dripping holes 521 in the Nth row to communicate, and the first water dripping holes 121 and the second water dripping holes 521 in the remaining same rows are staggered.

[0055] Exemplarily, when N is 3, the first water-dripping holes 121 on the first tip segment 12 are arranged in 3 rows along the direction pointing to its tip. The first water-dripping holes 121 in each row are evenly distributed along the circumferential direction of the first tip segment 12. Starting from one end close to the main body of the first drip irrigation pipe 1, the number of the first water-dripping holes 121 in the first row is the largest, the number in the second row is reduced compared with the first row, and the number in the third row (i.e., the row closest to the tip) is the smallest. For example, assuming there are 6 first water-dripping holes 121 in the first row, there may be 4 in the second row and 2 in the third row. The first water-dripping holes 121 on the second tip segment 52 are arranged in 3 rows along the direction pointing to its tip, and the specific distribution is the same as that of the first water-dripping holes 121 on the first tip segment 12. There are 3 second positioning members 61 provided on the outer wall of the second pipe body segment 51, and these 3 second positioning members 61 respectively correspond to the communication states of the first water-dripping holes 121 and the second water-dripping holes 521 in the first row, the second row, and the third row. When the first drip irrigation pipe 1 is rotated, the first drip irrigation pipe 1 drives the first positioning member 6 thereon. When the first positioning member 6 is rotationally connected to the third second positioning member 61, at this time, the first water-dripping holes 121 in the third row and the second water-dripping holes 521 in the third row are in communication, and at the same time, the first water-dripping holes 121 in the first row and the second row and the second water-dripping holes 521 are in an interleaved state. Similarly, when the first positioning member 6 is rotationally connected to the second second positioning member 61, at this time, the first water-dripping holes 121 in the second row and the second water-dripping holes 521 in the second row are in communication, and at the same time, the first water-dripping holes 121 in the first row and the third row and the second water-dripping holes 521 are in an interleaved state.

[0056] In this embodiment, by providing multiple rows of first water-dripping holes 121 and second water-dripping holes 521 and rotating the first drip irrigation pipe 1 to adjust the communication states of different rows of water-dripping holes to meet the water requirements of different crops, the above-mentioned method of adjusting the water output efficiency of the drip irrigation device does not require pulling out the drip irrigation device from the ground. Just rotating the first drip irrigation pipe 1 can achieve the adjustment of the water output efficiency of the drip irrigation device. The adjustment of the water volume is convenient and efficient. In addition, through the cooperation of the first positioning member 6 and the second positioning member 61, the rapid adjustment of the communication state of the water-dripping holes is realized, further improving the efficiency of the water volume adjustment of the drip irrigation device.

[0057] In some embodiments, the first positioning member 6 and the second positioning member 61 are magnetically connected.

[0058] In this embodiment, the first positioning member 6 and the second positioning member 61 are magnetically connected, which is convenient for connection and is not easily disconnected due to external forces (such as water flow impact, soil pressure, etc.). In addition, the relative stability between the first drip irrigation pipe 1 and the second drip irrigation pipe 5 is increased, thereby improving the stability of the drip irrigation device during use.
