Description

Technical Field

[0001] This utility model relates to the technical field of underground seepage irrigation devices, specifically a negative pressure self-priming anti-clogging underground seepage irrigation device. Background Technology

[0002] With the in-depth development of modern agricultural water-saving irrigation technology, subsurface irrigation has become a popular irrigation method due to its characteristics of directly delivering water to the crop roots, reducing evaporation loss, and improving water resource utilization. However, existing subsurface irrigation devices face many bottlenecks in practical applications. On the one hand, the irrigation pipes are easily blocked by soil particles, impurities in the water, and microbial metabolites, leading to poor water flow or even system paralysis. Frequent maintenance and cleaning not only increase labor costs but also affect the normal growth cycle of crops. On the other hand, most subsurface irrigation devices rely on external power equipment such as water pumps for water supply, which not only increases energy consumption and operating costs but also makes it difficult for the equipment to operate effectively in remote areas or areas without electricity where the power supply is unstable.

[0003] Meanwhile, traditional drip irrigation devices lack effective technical solutions to address clogging issues in their structural design, and cannot achieve automatic cleaning and anti-clogging functions. Existing self-priming drip irrigation devices have low self-priming efficiency and poor stability, making it difficult to meet the continuous and stable water requirements of crops. Therefore, we propose a negative pressure self-priming anti-clogging underground drip irrigation device. Utility Model Content

[0016] A negative pressure self-priming anti-clogging underground seepage irrigation device is provided, which has the following beneficial effects:

[0017] 1. Effectively prevents clogging and reduces maintenance costs: In the anti-clogging underground seepage component, the top anti-clogging permeable membrane can block soil particles, water impurities, etc., preventing them from entering the seepage pipe head and causing blockage. The internal conical seepage hole design can create a specific flow velocity and pressure distribution when the water flows into the seepage pipe head, reducing impurity deposition.

[0033] Structural Description:

[0034] Irrigation water storage tank 1: As the core water storage component of the device, the water inlet 2 on the top is used to introduce irrigation water and provide a water source guarantee for the entire irrigation process. The motor support platform 3 on the side provides a stable installation position for adjusting the drive motor 5 and ensures the stability of the motor when it is working. The drain outlet 4 on the side is connected to the connecting pipe 6 at its outer end. When the device is running, it is the channel for water in the tank to flow into the connecting pipe. At the same time, it can be used for drainage when the device needs to be cleaned or repaired.

[0035] Connecting transfer pipe 6: connects irrigation water storage tank 1 and negative pressure chamber pipe 7. A connection control component is set inside it. By adjusting the drive motor 5 to drive the internal sealing rotating plate 13 to rotate, the connection and blockage between irrigation water storage tank 1 and negative pressure chamber pipe 7, as well as the water flow rate, are controlled, playing a key role in connection and flow regulation.

[0036] Negative pressure chamber pipe 7: A negative pressure communication hole is opened on the top surface to connect the negative pressure drive component, so that the negative pressure generated by the negative pressure pump 9 can act on the inside of the pipe. The equally spaced installation holes on the bottom surface are used to fix the underground irrigation pipe 10. It is an important hub connecting the negative pressure drive component and the underground irrigation system, providing conditions for the formation of a negative pressure environment and guiding water flow into the underground irrigation pipe.

[0037] Underground irrigation pipe 10: The equidistantly distributed seepage pipe head installation holes 16 at the top are used to install seepage pipe heads 11, guide the water in the negative pressure chamber pipe 7 to the seepage pipe head, and then seep water into the soil through the seepage pipe head to realize the underground seepage irrigation function. It is the key channel for transporting irrigation water from the device to the roots of crops.

[0038] Adjustable drive motor 5: Fixedly installed on the top surface of motor support platform 3, serving as the power source for the communication control component. It converts electrical energy into mechanical energy. After being powered on, its output shaft rotates according to the set instructions, providing power for the rotation of the internal sealing rotating plate 13, thereby controlling the communication status and water flow rate between the irrigation water storage tank 1 and the negative pressure chamber pipe 7.

[0039] Internal sealing rotating plate 13: One end of it is fixedly connected to the output shaft of the regulating drive motor 5, and the other end rotates inside the connecting pipe 6. The shape and size of the internal sealing rotating plate 13 are adapted to the connecting pipe 6. When it rotates under the drive of the regulating drive motor 5, it can change the relative positional relationship between itself and the inner wall of the connecting pipe 6. Through this rotation, the connection between the irrigation water storage tank 1 and the negative pressure chamber pipe 7 can be controlled. When the internal sealing rotating plate 13 is fully open, the two pipes are connected and water can flow smoothly; when it is closed, the water flow is blocked.

[0040] Connecting pipe 8: One end is fixedly connected to the side of the negative pressure pump 9, and the other end is connected to the waterproof and breathable diaphragm 14 inside the negative pressure connecting hole on the top surface of the negative pressure chamber pipe 7. It is the channel through which the suction force generated by the negative pressure pump 9 is transmitted to the negative pressure chamber pipe 7. Its internal space provides a path for gas flow, ensuring that the negative pressure can effectively act on the inside of the negative pressure chamber pipe 7, so that a negative pressure environment is formed inside the pipe.

[0041] Negative pressure pump 9: Placed on the same ground as the bottom of irrigation water storage tank 1, it is powered by electricity. Its main function is to extract air, thereby reducing the air pressure in the pipes and creating a negative pressure environment. Under this negative pressure environment, the water in irrigation water storage tank 1 can flow smoothly to the negative pressure chamber pipe 7 under atmospheric pressure, providing power for irrigation.

[0042] Waterproof and breathable diaphragm 14: Fixed inside the negative pressure communication hole on the top surface of the negative pressure chamber pipe 7, it has waterproof and breathable properties. On the one hand, it allows air to pass through, enabling the negative pressure pump 9 to draw air from the negative pressure chamber pipe 7 to help form negative pressure. On the other hand, it can prevent external moisture, dust, impurities, etc. from entering the pipe, protecting the cleanliness of the pipe interior, ensuring the stability of the negative pressure environment, and also preventing external impurities from clogging the pipe or affecting the normal operation of the device.

[0043] Infiltration pipe head 11: Fixedly installed in the infiltration pipe head mounting hole 16 at the top of the underground irrigation pipe 10, it is a key component for realizing underground water infiltration. It has an internal sliding connecting plate 15 and an internal conical infiltration hole 18 at the top. The special shape of the internal conical infiltration hole 18 can form a specific flow velocity and pressure distribution when the water flows into the infiltration pipe head 11, which helps to reduce the deposition of impurities and improve the infiltration effect of the water flow. At the same time, it is also the outlet for the water flow from the underground irrigation pipe 10 to the soil.

[0044] Top anti-clogging permeable membrane 12: Fixed on the top surface of the seepage pipe head 11, it is made of special permeable material. Its main function is to block soil particles, water impurities, etc., to prevent these substances from entering the seepage pipe head 11, avoid clogging the seepage pipe head, ensure that water can flow smoothly through the seepage pipe head 11 and seep into the soil, and at the same time keep the inside of the pipe clean to ensure the normal operation of the irrigation system.

[0045] Internal sliding connecting plate 15: It is slidably connected to the inside of the seepage pipe head 11, and its top surface has equidistantly distributed side connecting holes 17. When the internal sliding connecting plate 15 slides inside the seepage pipe head 11, the side connecting holes 17 correspond to different positions inside the seepage pipe head 11, thereby changing the water flow channel. This structural design can prevent impurities from depositing in fixed positions, further prevent the seepage pipe head from being blocked, and ensure the stability and continuity of irrigation.

[0046] Working principle: When this utility model is needed, the adjusting drive motor 5 is started. The adjusting drive motor 5 on the motor support platform 3 drives the output shaft to rotate, thereby causing the internal sealing rotating plate 13 to rotate within the connecting pipe 6. When the internal sealing rotating plate 13 rotates to a specific angle, the irrigation water storage tank 1 is connected to the negative pressure chamber pipe 7, and the water in the tank can flow into the negative pressure chamber pipe 7. The negative pressure pump 9 is started, and the connecting pipe 8 connected to the side of the negative pressure pump 9 transmits the suction force generated by the negative pressure pump to the negative pressure chamber pipe 7. The waterproof and breathable diaphragm 14 prevents external impurities from entering on the one hand, and ensures gas exchange on the other hand, so that a stable negative pressure environment is formed inside the negative pressure chamber pipe 7. Under the action of negative pressure, the water in the irrigation water storage tank 1 flows into the negative pressure chamber pipe 7 through the connecting pipe 6. The water flows through the pressure chamber pipe 7 and then through the seepage pipe head installation hole 16 at the top of the underground irrigation pipe 10 into the seepage pipe head 11. The top anti-blocking permeable membrane 12 blocks soil particles, water impurities, etc., preventing them from entering the seepage pipe head 11. When the water flows through the internal conical seepage hole 18, the specific flow rate and pressure distribution reduce the deposition of impurities. The internal sliding connecting plate 15 can slide inside the seepage pipe head 11 and change the water flow channel through the side connecting hole 17 to further avoid blockage. The water finally seeps out from the seepage pipe head 11 to achieve underground seepage irrigation of the crop roots. When irrigation is completed or needs to be paused, the regulating drive motor 5 is restarted to rotate the internal sealing rotating plate 13 to the closed position, blocking the connection between the irrigation water storage tank 1 and the negative pressure chamber pipe 7 and stopping the water flow.
