Description

Technical Field

[0001] This invention relates to an irrigation conveying device, and more particularly to a cross-sectional hybrid anti-clogging irrigation conveying device for use in agricultural irrigation. Background Technology

[0002] Drip irrigation is a precise irrigation method that uses a low-pressure pipeline system to deliver water directly to the field. The water is then dripped evenly and slowly, drop by drop, into the soil near the crop root zone through emitters, orifices, or drip tapes installed on the capillary tubes, keeping the soil in the most developed root zone of the crop at a suitable level of moisture.

[0003] Chinese patent CN112262742B discloses a drip irrigation tape pressure stabilization and control system and method, including: a water pump, drip irrigation tape, multiple drip irrigation tapes, and a water distribution valve between the drip irrigation tape and the delivery pipeline; multiple pressure stabilizing devices installed inside the drip irrigation tape, with each pressure stabilizing device corresponding to a drip irrigation hole on the drip irrigation tape, ensuring that the water flow velocity through the drip irrigation hole on the same drip irrigation tape is the same; and a detection and adjustment device, with at least one detection and adjustment device installed outside each drip irrigation tape and located at the drip irrigation hole, used to detect the water flow rate through the drip irrigation hole and adjust the water flow velocity through the drip irrigation hole. This invention can perform drip irrigation according to the needs of crops and prevent silt in the water from clogging the drip irrigation hole.

[0004] Chinese patent CN112655526B discloses a water-saving irrigation system and method for cornfields. By automatically detecting soil moisture and sunlight intensity at multiple points in the cornfield, a centralized controller adjusts the working power of the water pump and the opening and closing degree of the branch valves and sprinkler solenoid valves according to the soil moisture and sunlight intensity, thereby adjusting the irrigation intensity and achieving water conservation while ensuring effective irrigation.

[0005] Most existing drip irrigation systems use valves or water pressure regulation to control the drip rate of the drip irrigation tape. However, this method changes the irrigation speed of the entire drip irrigation tape and uniformly regulates the irrigation amount along the entire drip irrigation tape. In actual environments, due to factors such as terrain and crop needs, the soil along the drip irrigation tape may have different irrigation requirements, but existing drip irrigation equipment is difficult to achieve local irrigation control. Summary of the Invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that existing drip irrigation equipment is difficult to achieve different irrigation control for local soil.

[0007] To address the aforementioned problems, this invention provides a cross-sectional hybrid anti-clogging irrigation delivery device, comprising a main water pipe and multiple uniformly distributed main drip irrigation tapes fixedly connected to the main water pipe, and at least one pair of auxiliary drip irrigation tapes. The auxiliary drip irrigation tapes are horizontally arranged on the multiple main drip irrigation tapes and distributed perpendicularly to the main drip irrigation tapes. The main drip irrigation tapes and auxiliary drip irrigation tapes are connected by a cross member. The cross member includes a square base, and a confluence groove is formed at the upper center of the square base. A main pipe groove is formed on one pair of non-adjacent inner walls of the confluence groove, and a secondary pipe groove is formed on the other pair of non-adjacent inner walls. The main drip irrigation tapes are placed inside a pair of main pipe grooves, and the auxiliary drip irrigation tapes are placed inside a pair of auxiliary pipe grooves.

[0008] The main drip irrigation tape and the auxiliary drip irrigation tape each have a main cut and an auxiliary cut in a local area inside the manifold. The inner walls of the main drip irrigation tape and the auxiliary drip irrigation tape are fitted with a pair of support rings. Multiple support rings are located inside the main pipe groove and the auxiliary pipe groove respectively. The upper end of the square seat is connected to a sealing element by a main bolt. The lower end of the sealing element is inserted into the main pipe groove and the auxiliary pipe groove respectively and abuts against the support rings on their inner sides.

[0009] The main pipe and the secondary pipe are also equipped with matching sealing fittings inside, and the upper end of the sealing fitting is connected to the square seat by a secondary bolt.

[0010] A cross-sectional hybrid anti-clogging irrigation delivery device, the method of using which includes the following steps:

[0011] Step 1, Whole Area Irrigation: In the agricultural area that needs irrigation, multiple main drip irrigation tapes are evenly connected to the main water pipe using the existing installation method. Then, the main water pipe is connected to the water source, and water is supplied to the main drip irrigation tapes through the main water pipe. The water flows out slowly through the small holes on the main drip irrigation tapes and seeps into the soil to achieve micro-irrigation.

[0012] Step 2, Localized Hydration:

[0013] S2.1. Based on the area of ​​the local area c that needs to be replenished with water, select multiple secondary drip irrigation tapes and distribute them evenly within area c;

[0014] S2.2 Cut a main cut and a secondary cut at the intersection of the main drip irrigation tape and the secondary drip irrigation tape, and place a pair of support rings into the main drip irrigation tape and the secondary drip irrigation tape through the main cut and the secondary cut. Use a cross connector to connect the intersection of the main drip irrigation tape and the secondary drip irrigation tape.

[0015] S2.3 At this time, the water flow in the main drip irrigation tape is transported to the secondary drip irrigation tape through the cross-joint, and also seeps into the soil through the small holes on the secondary drip irrigation tape, so that in the local area c, the main drip irrigation tape and the secondary drip irrigation tape are combined to achieve longitudinal and transverse mixed micro-irrigation;

[0016] Step 3: Local Area Traffic Stop:

[0017] S3.1. Based on the lateral width of the local area a where irrigation needs to be stopped, select a pair of auxiliary drip irrigation tapes of appropriate length and place the pair of auxiliary drip irrigation tapes on both sides of the longitudinal direction of the local area a.

[0018] S3.2, repeat S2.2;

[0019] S3.3 Select multiple sealing pipe fittings and insert them into multiple cross fittings to completely squeeze and block the multiple main drip irrigation tapes flowing through area a, so that there is no obvious water flow in the multiple main drip irrigation tapes in area a, while water still flows in the main drip irrigation tapes in other areas, thus achieving the cessation of flow in area a and normal micro-irrigation in other areas.

[0020] Step 4, Local Throttling:

[0021] S4.1. Based on the required lateral width of the local area b to be throttled, select a pair of auxiliary drip irrigation tapes of appropriate length and place the pair of auxiliary drip irrigation tapes on both sides of the longitudinal direction of the local area b.

[0022] S4.2, repeat S2.2;

[0023] S4.3 Select multiple sealing pipe fittings and insert them intermittently into the cross fittings to intermittently squeeze and seal the multiple main drip irrigation tapes flowing through area b, thereby increasing the irrigation spacing in area b and achieving water-saving irrigation in area b.

[0024] As a further supplement to this application, the sealing element includes a cover plate and a pair of short vertical plates and a pair of long vertical plates fixedly connected to the lower end of the cover plate. The pair of short vertical plates are respectively inserted into a pair of main pipe slots and abut against the support rings on their inner sides. The pair of long vertical plates are respectively inserted into a pair of secondary pipe slots and abut against the support rings on their inner sides.

[0025] As a further supplement to this application, the cover plate is provided with multiple screw holes, and the upper end of the square seat is provided with multiple screw grooves. The main bolt passes through the screw holes and is threaded into the inside of the screw grooves.

[0026] As a further supplement to this application, the sealing fitting includes a crossbar and a pressure plate fixedly connected to the lower end of the crossbar. A pair of locking holes are provided on the crossbar, and multiple threaded grooves are provided at the upper end of the square seat. The secondary bolt passes through the locking holes and is threaded into the interior of the threaded grooves.

[0027] As a further supplement to this application, the inner bottom surfaces of the main pipe and the auxiliary pipe are both concave semi-circular structures, the lower ends of the short vertical plate and the long vertical plate are both concave semi-circular structures, and the lower end of the pressure plate is a convex semi-circular structure that matches the concave semi-circular structure.

[0028] As a further supplement to this application, the outer ends of the short vertical plate, the long vertical plate, and the pressure plate, as well as the inner walls of the main pipe groove and the auxiliary pipe groove, are all fixedly connected with elastic sealing layers.

[0029] As another improvement of this application, the inside of the square base is fixedly connected with an inlet pipe and an outlet pipe, and both ends of the inlet pipe and the outlet pipe are connected to the manifold and the outside. The ends of the inlet pipe and the outlet pipe that are connected to the manifold are threadedly connected to one end of a hose. One end of the hose away from the inlet pipe passes through the main cut and is placed inside the main drip irrigation belt, and the other end of the hose away from the outlet pipe passes through the secondary cut and is placed inside the secondary drip irrigation belt.

[0030] As a further improvement to this application, the end of the inlet pipe away from the hose is connected to the outlet of an external water pump, and the end of the outlet pipe away from the hose is connected to the inlet of an external water pump.

[0031] In summary, this application, by laying secondary drip irrigation tape longitudinally on existing horizontally uniformly laid main drip irrigation tape and sealing the intersection of the main and secondary drip irrigation tapes with cross-connectors, serves as the water flow convergence point between the two. During irrigation, based on the different irrigation needs of different soil areas, on the one hand, the mixed main and secondary drip irrigation tapes can be used to intensify irrigation in localized areas; on the other hand, the cross-connectors can be used to block the inlet or outlet of the main drip irrigation tape, preventing water flow through the middle sections of multiple main drip irrigation tapes in localized soil areas, enabling localized flow cessation or flow-saving irrigation operations, while the remaining areas remain under normal micro-irrigation conditions. Therefore, this application effectively achieves dynamic adjustment and optimization of irrigation schemes according to soil or crop needs. Attached Figure Description

[0048] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0049] Implementation method 1:

[0050] This invention provides a cross-sectional hybrid anti-clogging irrigation delivery device; please refer to [link / reference]. Figure 1 and Figure 2 It includes a main water pipe 1 and multiple evenly distributed main drip irrigation tapes 2 that are fixedly connected to the main water pipe 1. The main water pipe 1 and the main drip irrigation tapes 2 are the existing drip irrigation laying methods. The two are generally connected by a joint. The main drip irrigation tapes 2 can be patch-type drip irrigation tapes, and the water inside overflows through small holes on the patch.

[0051] Please see Figure 2 , Figure 3 and Figure 4 This application also includes at least one pair of auxiliary drip irrigation tapes 3, which are of the same type as the main drip irrigation tapes 2. The auxiliary drip irrigation tapes 3 are horizontally arranged on multiple main drip irrigation tapes 2 and distributed perpendicularly to the main drip irrigation tapes 2. The main drip irrigation tapes 2 and the auxiliary drip irrigation tapes 3 are connected by a cross member. The cross member includes a square base 4. A confluence groove is provided at the upper center of the square base 4. A main pipe groove 401 is provided on one pair of non-adjacent inner walls of the confluence groove, and a secondary pipe groove 402 is provided on the other pair of non-adjacent inner walls. The center lines of the pair of main pipe grooves 401 are on the same straight line, and the center lines of the pair of secondary pipe grooves 402 are on the same straight line. This makes it convenient to place the main drip irrigation tape 2 inside the pair of main pipe grooves 401 and the auxiliary drip irrigation tape 3 inside the pair of secondary pipe grooves 402.

[0052] Please see Figure 4 and Figure 5 The main drip irrigation tape 2 and the auxiliary drip irrigation tape 3 each have a main incision 201 and an auxiliary incision 301 respectively in local areas inside the manifold (these can be formed by the following methods: such as...). Figure 6 As shown, a long notch is cut at the crease edge of the unused flat main drip irrigation tape 2 (or auxiliary drip irrigation tape 3) using a cutter. A pair of support rings 6 are fitted to the inner walls of both the main drip irrigation tape 2 and the auxiliary drip irrigation tape 3. The outer diameter of the support rings 6 is the same as the inner diameter of the main drip irrigation tape 2 and the auxiliary drip irrigation tape 3. Since the main drip irrigation tape 2 and the auxiliary drip irrigation tape 3 are flexible structures, the support rings 6 can be inserted into the corresponding main drip irrigation tape 2 or auxiliary drip irrigation tape 3 through the main cut 201 or the auxiliary cut 301. After insertion, the placement and state of the support rings 6 are adjusted so that the support rings 6 support the interior of the main drip irrigation tape 2 and the auxiliary drip irrigation tape 3. This ensures that when the main drip irrigation tape 2 and the auxiliary drip irrigation tape 3 are installed into the square base 4, the multiple support rings 6 are located inside the main pipe groove 401 and the auxiliary pipe groove 402, respectively.

[0053] Please see Figure 3 and Figure 7 The upper end of the square base 4 is connected to a sealing element 5 via a main bolt. Multiple screw holes are provided on the cover plate 51, and multiple screw grooves 403 are provided on the upper end of the square base 4. The main bolt passes through the screw holes and is threaded into the inside of the screw grooves 403. Figure 5 and Figure 8 As shown, the sealing component 5 includes a cover plate 51 and a pair of short vertical plates 52 and a pair of long vertical plates 53 fixedly connected to the lower end of the cover plate 51. The pair of short vertical plates 52 are respectively inserted into a pair of main pipe grooves 401 and abut against the support rings 6 on their inner sides. The pair of long vertical plates 53 are respectively inserted into a pair of secondary pipe grooves 402 and abut against the support rings 6 on their inner sides. The support rings 6 are rigid structures.

[0054] Please see Figure 5 and Figure 7 The inner bottom surfaces of the main drip irrigation channel 401 and the secondary drip irrigation channel 402 are both concave semi-circular structures, which match the shape of the main drip irrigation tape 2 and the secondary drip irrigation tape 3 after they are fully filled with water. The lower ends of the short vertical plate 52 and the long vertical plate 53 are both concave semi-circular structures, which facilitates matching with the annular structure of the support ring 6. The inner walls of the short vertical plate 52, the long vertical plate 53, the main drip irrigation channel 401, and the secondary drip irrigation channel 402 are all fixedly connected with an elastic sealing layer, such as elastic sealing rubber, which can improve the tightness of the connection between the above structures and with other structures (such as the contact between the short vertical plate 52, the long vertical plate 53 and the support ring 6).

[0055] Since the depth of the main drip channel 401 is less than the depth of the secondary drip channel 402, after the main drip tape 2 and the secondary drip tape 3 are installed in the square seat 4, the main drip tape 2 is located on the upper side of the secondary drip tape 3. During irrigation, the water in the main drip tape 2 will flow out through the main cut 201, gather in the confluence channel, and enter the secondary drip tape 3 through the secondary cut 301. Through the tight fit between the short vertical plate 52 and the main drip channel 401, the tight fit between the long vertical plate 53 and the secondary drip channel 402, and the squeezing fit between the short vertical plate 52, the long vertical plate 53 and the support ring 6, the confluence channel is closed around the perimeter. Combined with the sealing of the upper end of the confluence channel by the cover plate 51, the square seat 4 serves as the water confluence point between the main drip tape 2 and the secondary drip tape 3. At the same time, the confluenced water is not easy to overflow or leak outward, and it is not easy to affect the irrigation of the soil.

[0056] Please see Figure 9 and Figure 10 The main pipe channel 401 and the secondary pipe channel 402 are also equipped with matching sealing components 7. The upper end of the sealing component 7 is connected to the square seat 4 by a secondary bolt 8. The sealing component 7 includes a crossbar 71 and a pressure plate 72 fixedly connected to the lower end of the crossbar 71. A pair of locking holes are opened on the crossbar 71. The upper end of the square seat 4 is opened with multiple threaded grooves 404. The secondary bolt 8 passes through the locking holes and is threaded into the inside of the threaded grooves 404. The lower end of the pressure plate 72 has a downward convex semi-circular structure, which is convenient to match the downward concave semi-circular structure of the inner bottom surface of the main pipe channel 401 and the secondary pipe channel 402. The outer end of the sealing component 7 is also fixedly connected with an elastic sealing layer. When the main drip irrigation tape 2 or the secondary drip irrigation tape 3 is sealed by the sealing component 7, it is effectively squeezed into a flat shape (in combination with...). Figure 11 As shown in the figure, this makes it difficult for water to flow through the squeezed area.

[0057] A cross-sectional hybrid anti-clogging irrigation delivery device, the method of using which includes the following steps:

[0058] Step 1, Comprehensive Irrigation: In the agricultural area requiring irrigation, multiple main drip irrigation tapes 2 are evenly connected to the main water pipe 1 using the existing installation method. The main water pipe 1 is then connected to a water source, supplying water to the main drip irrigation tapes 2. The water slowly flows out through small holes in the main drip irrigation tapes 2, infiltrating into the soil to achieve micro-irrigation. This irrigation method is an existing drip irrigation method (such as...). Figure 1 (As shown in the upper left corner of the structure).

[0059] Step 2, Localized Hydration:

[0060] S2.1. Based on the area of ​​the local area c that needs to be replenished with water, select multiple secondary drip irrigation tapes 3 and distribute them evenly within the area c;

[0061] S2.2 Cut a main cut 201 and a secondary cut 301 at the intersection of the main drip irrigation tape 2 and the secondary drip irrigation tape 3, respectively, and place a pair of support rings 6 in both the main drip irrigation tape 2 and the secondary drip irrigation tape 3 through the main cut 201 and the secondary cut 301. Use the cross piece to connect the intersection of the main drip irrigation tape 2 and the secondary drip irrigation tape 3.

[0062] S2.3, such as Figure 1 As shown in the lower right corner of the structure, the water in the main drip irrigation belt 2 is transported to the secondary drip irrigation belt 3 through the cross member, and also seeps into the soil through the small holes on the secondary drip irrigation belt 3, so that in the local area c, the main drip irrigation belt 2 and the secondary drip irrigation belt 3 are combined to achieve longitudinal and transverse mixed micro-irrigation.

[0063] Step 3: Local Area Traffic Stop:

[0064] S3.1. Based on the lateral width of the local area a where irrigation needs to be stopped, select a pair of auxiliary drip irrigation tapes 3 of appropriate length and place the pair of auxiliary drip irrigation tapes 3 on both sides of the longitudinal direction of the local area a.

[0065] S3.2, repeat S2.2;

[0066] S3.3 Select multiple sealing fittings 7 and insert them into multiple intersecting fittings to completely seal the multiple main drip irrigation tapes 2 flowing through area a. This results in no significant water flow through the main drip irrigation tapes 2 in area a, while water flow remains in the main drip irrigation tapes 2 in other areas. This achieves flow cessation in area a, while normal micro-irrigation continues in other areas (e.g., Figure 1 The structure shown in the upper right corner or as follows Figure 2 (as shown)

[0067] For a detailed explanation of the interruption principle, please refer to... Figure 2 , Figure 11 and Figure 12First, for the multiple square seats 4 on the secondary drip irrigation tape 3 near the main water pipe 1, except for a pair of square seats 4 on both sides of the edge, sealing pipe parts 7 are installed on the remaining square seats 4. The sealing pipe parts 7 are installed in the main pipe groove 401 on the side away from the main water pipe 1, and the water outlet of the main drip irrigation tape 2 is squeezed and blocked (e.g. Figure 12 As shown), this prevents the main drip irrigation tape 2 from continuing to supply water to subsequent parts, ensuring that there is no significant water flow through the main drip irrigation tape 2 entering area a. Secondly, for the multiple square seats 4 on the secondary drip irrigation tape 3 on the side away from the main water pipe 1, except for a pair of square seats 4 on both sides of the edge, sealing pipe fittings 7 are installed on the remaining square seats 4. The sealing pipe fittings 7 are installed in the main pipe groove 401 on the side closest to the main water pipe 1 (e.g., Figure 11 and 12 As shown), this makes it difficult for the water flow in the manifold to flow back into the main drip irrigation belt 2, thereby effectively ensuring that there is no obvious water flow in the main drip irrigation belt 2 in area a, that is, area a cannot be irrigated;

[0068] Furthermore, since both square seats 4 on the edges can serve as the water convergence points for the main drip irrigation tape 2 and the secondary drip irrigation tape 3, and the secondary drip irrigation tape 3 is not blocked, for the main drip irrigation tape 2 behind area a, although the main drip irrigation tape 2 cannot converge water into the collection channel, at this time, due to the water pressure (water pressure is required for water to overflow through the small holes on the patch), the water in the secondary drip irrigation tape 3 will be released in the reverse direction into the collection channel through the secondary cut 301, and then enter the main drip irrigation tape 2 through the main cut 201 (e.g., Figure 11 As shown in the figure, the main drip irrigation strip 2 behind area a can play a normal irrigation role.

[0069] Step 4, Local Throttling:

[0070] S4.1. Based on the required lateral width of the local area b to be throttled, select a pair of auxiliary drip irrigation tapes 3 of appropriate length and set the pair of auxiliary drip irrigation tapes 3 on both sides of the longitudinal direction of the local area b.

[0071] S4.2, repeat S2.2;

[0072] S4.3 Select multiple sealing pipe fittings 7 and insert them intermittently into the cross fittings to intermittently squeeze and seal the multiple main drip irrigation tapes 2 flowing through area b, thereby increasing the irrigation spacing within area b and achieving water-saving irrigation in area b (e.g., Figure 1 As shown in the lower left corner of the structure, its principle of blocking the main drip irrigation tape 2 is the same as in step three, except that the number of main drip irrigation tapes 2 that are blocked is reduced. In an adjacent pair of main drip irrigation tapes 2, one main drip irrigation tape 2 is irrigating normally, while the other main drip irrigation tape 2 stops irrigating, thereby increasing the irrigation spacing.

[0073] The second implementation method:

[0074] This embodiment adds the following structure based on the first embodiment: Please refer to Figure 13 and Figure 14 The square base 4 is internally fixedly connected to an inlet pipe 91 and an outlet pipe 92. Both ends of the inlet pipe 91 and the outlet pipe 92 are connected to the manifold and the outside. The ends of the inlet pipe 91 and the outlet pipe 92 that are connected to the manifold are threadedly connected to one end of a hose 10. One end of the hose 10 away from the inlet pipe 91 passes through the main cut 201 and is placed inside the main drip irrigation belt 2. The other end of the hose 10 away from the outlet pipe 92 passes through the secondary cut 301 and is placed inside the secondary drip irrigation belt 3.

[0075] During use, the following operations can be performed periodically: Connect the end of the inlet pipe 91 furthest from the hose 10 to the outlet of the external water pump, and connect the end of the outlet pipe 92 furthest from the hose 10 to the inlet of the external water pump. Start the external water pump to draw water from the secondary drip irrigation belt 3 through the hose 10 and inject it into the main drip irrigation belt 2. This not only accelerates the water flow rate in both the main drip irrigation belt 2 and the secondary drip irrigation belt 3, but also causes the water injected into the main drip irrigation belt 2 to impact and collide with the original water flow inside, creating turbulence in the main drip irrigation belt 2, thereby achieving a smooth flow. In terms of both direction and flow rate, it facilitates the removal of impurities from the inner walls or small holes of the main drip irrigation tape 2 and the auxiliary drip irrigation tape 3, effectively alleviating drip irrigation blockage. Furthermore, due to the early reduction of impurity adhesion, staff can visually observe the turbidity of the water flow in the square seat 4 by opening the seal 5, which can effectively determine the accumulation of impurities in the main drip irrigation tape 2 and the auxiliary drip irrigation tape 3, thereby enabling timely backwashing of the main drip irrigation tape 2 and the auxiliary drip irrigation tape 3. At the same time, the early removal of impurities also effectively reduces the flushing time of the main drip irrigation tape 2 and the auxiliary drip irrigation tape 3 in the later stages.

[0076] For the inlet pipe 91 and outlet pipe 92 that are not equipped with hose 10 and external water pump, a threaded plug can be used to seal one end of the inlet pipe 91 and outlet pipe 92 to prevent water in the manifold from overflowing outwards through them.

[0077] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
