Description

Technical Field

[0001] This invention relates to the field of drip irrigation technology, and more specifically, to a drip irrigation device for green belts based on polymer materials and its connection method. Background Technology

[0002] Highway green belts serve multiple functions: separating traffic and ensuring safety, beautifying the city, reducing driver fatigue, and altering the spatial scale of roads through the trees planted within them, creating a better width-to-height ratio. Furthermore, they purify the environment by trapping dust, reducing noise, absorbing harmful gases, and releasing oxygen. While roadside greenery is a major element of the environmental landscape, the irrigation and maintenance of existing green belts are challenging. Typical green belts can extend for several to tens of kilometers in width. Traditional irrigation methods, often using water trucks for manual irrigation, are not only water-intensive but also prone to leaks and water runoff, resulting in low water resource utilization. Most importantly, manual irrigation poses risks to traffic safety and is difficult to maintain. Therefore, most existing green belts now utilize drip irrigation, which delivers water to the roots of crops through plastic pipes via orifices or drippers for localized irrigation.

[0003] However, existing drip irrigation devices cannot adjust the amount of water used for drip irrigation in real time according to actual needs, which can easily lead to excessive water usage in green belts and waste of water resources. Therefore, it is necessary to invent a drip irrigation device for green belts based on polymer materials to solve this problem. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a drip irrigation device and drip irrigation method for green belts based on polymer materials, so as to solve the problem mentioned in the background art that the traditional existing drip irrigation devices cannot adjust the drip irrigation water volume in real time according to actual needs, which easily leads to excessive water for irrigation of green belts and waste of water resources.

[0010] Optionally, the horizontal angle adjustment mechanism includes a fixed plate, a first fixed gear, a first limiting gear, a sliding rod, a limiting plate, a rotating column, and a mounting bracket. The fixed plate is fixedly connected to the outside of the water tank assembly. The first fixed gear is rotatably connected above the fixed plate.

[0013] Optionally, the following steps are included: S1: When there is water in the main body of the water storage tank, the rainwater stored in the water storage tank is used to drip irrigate the green belt. The rainwater flows through the bottom of the main body of the water storage tank to the inner drip pipe, and then through the drip hole of the inner drip pipe to the outer drip hole group of the outer drip pipe, and drips into the green belt through the outer drip hole group. S2: When it is necessary to adjust the dripping water volume, the operator turns on the first motor. The first motor rotates, which drives the adjusting gear to rotate. The adjusting gear rotates, which drives the adjusting gear ring to rotate. The rotating gear ring in turn drives the external dripping tube to rotate. The dripping water volume is adjusted by using different numbers of external dripping hole groups. S3: When the rainwater stored in the main body of the water storage tank is used up, turn on the water pump to allow municipal water to enter the water pump through the inlet pipe, and then pump it into the main body of the water storage tank. Then, drip irrigation is carried out on the green belt through the inner and outer drip pipes. S4: When too many leaves and other debris accumulate above the filter plate, affecting rainwater's passage through the filter plate into the main body of the water storage tank, the operator turns on the second motor to rotate it. The rotation of the second motor drives the rotating rod to rotate, which in turn drives the cleaning paddle and cleaning brush to rotate, thereby cleaning the filter plate through the cleaning brush. S5: When adjusting the angle of the solar panel, the operator first pulls the sliding rod upward to move the first limiting gear ring upward and disengage it from the first fixed gear. At this time, the operator can rotate the rotating column and drive the mounting frame to rotate. The rotation of the mounting frame drives the solar panel to rotate, thereby adjusting the horizontal angle. After the adjustment is completed, the operator pulls the sliding rod downward to move the first limiting gear ring downward and engage it with the first fixed gear again to limit the angle. S6: After the horizontal angle adjustment is completed, the operator rotates the adjusting screw. The rotation of the adjusting screw drives the second limiting gear ring to move and disengage from the second fixed gear. Then, the operator can rotate the rotating shaft to adjust the elevation angle of the solar panel. After the elevation angle is adjusted, the operator rotates the adjusting screw again and drives the second limiting gear ring to move until it re-engages with the second fixed gear and is limited. At this point, the angle adjustment of the solar panel is completed.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention provides a drip irrigation assembly comprising an inner drip tube, inner drip holes, an outer drip tube, an outer drip hole group, a sealing rubber layer, an adjusting gear ring, a first motor, and an adjusting gear. In practical use, the first motor can be activated to rotate according to actual drip irrigation needs. The rotation of the first motor drives the adjusting gear, which in turn drives the adjusting gear ring, which in turn drives the outer drip tube. By rotating different numbers of outer drip hole groups to overlap with the inner drip holes, the drip volume can be adjusted, avoiding excessive drip irrigation and water waste. Furthermore, drip irrigation can be tailored to the needs of green belts, improving their growth and condition. The sealing rubber layer prevents waste by sealing inactive inner drip holes. 2. This invention features a cleaning mechanism equipped with a second motor, a rotating rod, a cleaning paddle, and a cleaning brush. When excessive debris such as leaves accumulates above the filter plate, hindering rainwater from passing through the filter plate and entering the main body of the water storage tank, the operator can activate the second motor. The rotation of the second motor drives the rotating rod, which in turn drives the cleaning paddle and cleaning brush. This cleaning brush cleans the filter plate, preventing blockage and ensuring the water storage tank effectively receives rainwater. 3. This invention uses a photovoltaic panel assembly with both horizontal and vertical adjustment mechanisms. This allows the horizontal and vertical angles of the solar panel to be adjusted according to the actual installation location of the drip irrigation device and the surrounding environment during use. This enables the solar panel to fully receive sunlight, improves power generation efficiency, and thus better supplies energy to the drip irrigation device. Attached Figure Description

[0025] Specifically, the steps for using this device to connect CPVC pipes are as follows: S1: When there is water in the main body 12 of the water storage tank, the rainwater stored in the water storage tank is used to drip irrigate the green belt. The rainwater flows through the bottom of the main body 12 of the water storage tank to the inner drip pipe 21, and then through the drip hole of the inner drip pipe 21 to the outer drip hole group 24 of the outer drip pipe 23, and drips onto the green belt through the outer drip hole group 24. S2: When it is necessary to adjust the dripping water volume, the operator turns on the first motor 27. The first motor 27 rotates and drives the adjusting gear 28 to rotate. The adjusting gear 28 rotates and drives the adjusting gear ring 26 to rotate. The adjusting gear ring 26 rotates and drives the external drip tube 23 to rotate. The dripping water volume is adjusted by using different numbers of external dripping hole groups 24. S3: When the rainwater stored in the main body 12 of the water storage tank is used up, turn on the water pump 15. The municipal water enters the water pump 15 through the inlet pipe 16 and is then transported to the inside of the main body 12 of the water storage tank through the water pump 15. Then, the green belt is drip-irrigated through the inner drip pipe 21 and the outer drip pipe 23. S4: When too many leaves and other debris accumulate above the filter plate 13, affecting the rainwater's passage through the filter plate 13 into the main body of the water storage tank 12, the operator turns on the second motor 42 to rotate it. The rotation of the second motor 42 drives the rotating rod 43 to rotate, which in turn drives the cleaning paddle 44 and the cleaning brush 45 to rotate, thereby cleaning the filter plate 13 through the cleaning brush 45. S5: When adjusting the angle of the solar panel 328, the operator first pulls the sliding rod 314 upward to move the first limiting gear ring 313 upward and disengage it from the first fixed gear 312. At this time, the operator can rotate the rotating column 316 and drive the mounting bracket 317 to rotate. The rotation of the mounting bracket 317 drives the solar panel 328 to rotate, thereby adjusting the horizontal angle. After the adjustment is completed, the operator pulls the sliding rod 314 downward to move the first limiting gear ring 313 downward and re-engage it with the first fixed gear 312 to limit the angle. S6: After the horizontal angle adjustment is completed, the operator rotates the adjusting screw 326. The rotation of the adjusting screw 326 drives the second limiting gear ring 325 to move and disengage from the second fixed gear 322. Then, the operator can rotate the rotating shaft 321 to adjust the elevation angle of the solar panel 328. After the elevation angle is adjusted, the operator rotates the adjusting screw 326 again and drives the second limiting gear ring 325 to move until it re-engages with the second fixed gear 322 and is limited. At this time, the angle adjustment of the solar panel 328 is completed.

S3: When the rainwater stored in the main body (12) of the water storage tank is used up, turn on the water pump (15) and use the water pump (15) to allow municipal water to enter the water pump (15) through the inlet pipe (16), and then use the water pump (15) to transport it to the inside of the main body (12) of the water storage tank, and then use the inner drip pipe (21) and the outer drip pipe (23) to drip irrigate the green belt; S4: When too many leaves and other debris piled up above the filter plate (13) affect the rainwater from entering the main body of the water storage tank (12) through the filter plate (13), the operator turns on the second motor (42) to rotate. The rotation of the second motor (42) drives the rotating rod (43) to rotate. The rotation of the rotating rod (43) drives the cleaning paddle (44) and the cleaning brush (45) to rotate, thereby cleaning the filter plate (13) through the cleaning brush (45). S5: When adjusting the angle of the solar panel (328), the operator first pulls the sliding rod (314) upward to drive the first limiting gear ring (313) to move upward and disengage from the first fixed gear (312). At this time, the operator can rotate the rotating column (316) and drive the mounting frame (317) to rotate. The rotation of the mounting frame (317) drives the solar panel (328) to rotate, thereby adjusting the horizontal angle. After the adjustment is completed, the operator pulls the sliding rod (314) downward to drive the first limiting gear ring (313) to move downward and re-engage with the first fixed gear (312) to limit the position. S6: After the horizontal angle adjustment is completed, the operator rotates the adjusting screw (326). The rotating screw (326) drives the second limiting gear ring (325) to move and disengage from the second fixed gear (322). Then the operator can rotate the rotating shaft (321) to adjust the elevation angle of the solar panel (328). After the elevation angle is adjusted, the operator rotates the adjusting screw (326) again and drives the second limiting gear ring (325) to move until it meshes with the second fixed gear (322) again and is limited. At this time, the angle adjustment of the solar panel (328) is completed.
