[0023] The present invention has at least the following beneficial effects:

[0024] 1. When the agricultural water-saving automatic irrigation valve is in use, the water flow impacts the starting structure to make it rotate. In this process, the kinetic energy of the water flow is converted into the rotational kinetic energy of the drum. The gear assembly is used to drive the rotating shaft. The rotation of the rotating shaft drives the two first spheres to rotate. When the two first spheres rotate, centrifugal force is generated to expand outward, so that the push rod is used to drive the first installation sleeve to move upward. The upward movement of the first installation sleeve drives the valve to flip through the hinged cooperation of the connecting piece to realize automatic water supply. In this way, the automatic opening and closing of the valve can be realized only by the power of the water flow.

[0025] 2. When the rotary cylinder in the agricultural water-saving automatic irrigation valve rotates at a high speed, the transmission gear ring at its bottom rotates and meshes with the linkage gear to drive the installation shaft to rotate. The rotation of the installation shaft utilizes the transmission cooperation of the synchronous wheel and the synchronous belt to drive the rotating shaft to rotate at a high speed. The rotation of the rotating shaft drives the two second spheres to rotate. When the second spheres rotate, centrifugal force is generated to expand outward, thereby driving the displacement of the second sleeve. The displacement of the second sleeve extends the extension plate through the push rod, further increasing the impact surface of the water flow impact plate, so that it can adapt to different water flow conditions and operation requirements.

[0026] 3. The agricultural water-saving automatic irrigation valve can adjust the preload force of the pressure regulating spring by plugging and matching the positioning rod with the regulating hole, so as to better control the thrust generated by the centrifugal movement of the first sphere.

[0027] 4. For this agricultural water-saving automatic irrigation valve, when the water flow impacts the starting structure and causes the drum to rotate, the movement of the eccentric structure will automatically adjust the position of the extension plate, thereby offsetting the external impact to a certain extent. Since the extension plate is retractable and hinged to the eccentric structure, the valve can adapt to different water flow conditions and operating requirements. This design enables the system to maintain high flexibility and response speed when facing water flow fluctuations or changes, thereby enhancing the stability of the valve.

The top end of the rotating drum 301 and the bottom end of the rotating shaft 401 are provided with a driving gear assembly 5.

[0041] Specifically, the gear assembly 5 is composed of two meshing gears, and the two gears are fixedly mounted on the bottom end of the rotating shaft 401 and the top end of the drum 301, respectively. The water flow impacts the starting structure 3 to make it rotate. In this process, the kinetic energy of the water flow is converted into the rotational kinetic energy of the drum 301, thereby realizing energy conversion and utilization, and improving the energy utilization efficiency of the entire valve body system. Both ends of the drum 301 pass through the interior of the valve tube 1, and the drum 301 is connected to the internal bearing of the valve tube 1.

The interiors of the first sliding sleeve 404 and the first mounting sleeve 406 are both hollow.

[0043] It should be noted that the automatic opening and closing of the valve can be achieved through the power of water flow, realizing the advantages of automated control, energy saving and high efficiency, and strong adaptability, reducing dependence on electronic equipment, and having high reliability. Mechanical automatic control systems usually have high reliability because their operation does not rely on complex electronic logic or software algorithms. Under harsh environmental conditions, such as high temperature, humidity or strong electromagnetic interference environment, the system can still maintain stable operation. The design concept of the system integrates mechanical transmission, fluid dynamics and automatic control principles, and provides new ideas and technical means for automated control in the fields of water treatment, irrigation systems, fire protection systems, etc.

[0044] To ensure stable operation of the rotating shaft 401, in the present embodiment, a limiting horizontal plate 6 is fixedly installed on the outer wall of one end of the valve tube 1 close to the valve 2, the bottom end of the rotating shaft 401 is connected to the internal bearing of the limiting horizontal plate 6, and a limiting frame 61 supporting the first connecting rod 4071 is fixedly installed on the upper surface of the limiting horizontal plate 6, and the outer surface of the first connecting rod 4072 is rotatably connected to the top of the limiting frame 61.

The top end of the pressure regulating spring 4082 is rotatably connected to the lower surface of the first mounting sleeve 406, and the bottom end of the pressure regulating spring 4082 is fixed to the top end of the ring sleeve 4081, the top end of the positioning ring 4083 is fixed to the bottom end of the ring sleeve 4081, and a positioning rod 4084 which is plugged into the rotating shaft 401 is inserted into the interior of the positioning ring 4083; a plurality of adjusting holes 4085 which are equidistantly arranged are opened in the interior of the rotating shaft 401, and the positioning rod 4084 is plugged into the adjusting hole 4085 to achieve the fixation of the positioning ring 4083 and the adjustment of the preload force of the pressure regulating spring 4082, so as to better control the thrust generated when the first sphere 403 is centrifuged.

[0046] In order to further improve the adaptability of the device, in this embodiment, Figure 6 - Figure 8As shown, an adjusting mechanism 7 is arranged inside the rotating drum 301, and the adjusting mechanism 7 includes a rotating shaft 701 rotatably arranged inside the rotating drum 301 and an eccentric structure 702 arranged on the outer surface of the rotating shaft 701 and connected to the pushing plate 303; the eccentric structure 702 includes a mounting seat 7021 fixedly mounted on the outer surface of the rotating shaft 701, a second swing arm 7022 hingedly mounted on the outer surface of the mounting seat 7021, a second sphere 7023 fixedly mounted on the other end of the second swing arm 7022, a second sliding sleeve 7024 slidably sleeved on the outer surface of the rotating shaft 701, and a second mounting sleeve 7025 rotatably mounted on the outer surface of the second sliding sleeve 7024, a connecting rod 7026 is hingedly mounted on the outer surface of the second sliding sleeve 7024, a push rod 703 is hingedly mounted on the outer surface of the second mounting sleeve 7025, and the connecting rod 702 The other end of the push rod 703 is hinged to the outer surface of the second swing arm 7022, the other end of the push rod 703 is hinged to the side of the push plate 303 away from the extension plate 304, and a return spring 7027 is rotatably installed between the mounting seat 7021 and the second sliding sleeve 7024, which surrounds the outer surface of the rotating shaft 701; in order to improve the linkage of the structure, in this embodiment, the bottom end of the rotating drum 301 and the rotating shaft 701 is provided with a transmission mechanism 8, which includes a transmission ring gear 801 fixedly installed on the lower surface of the rotating drum 301, a mounting shaft 802 rotatably arranged below the rotating drum 301, a linkage gear 803 fixedly installed on the outer surface of the mounting shaft 802 and meshing with the transmission ring gear 801, and a synchronous wheel 804 fixedly installed on the bottom end of the rotating shaft 701 and the mounting shaft 802, and a synchronous belt 805 is connected between the two synchronous wheels 804. Both ends of the rotating shaft 701 pass through the interior of the rotating drum 301, and the top end of the rotating shaft 701 is connected to the bearing on the lower surface of the limiting horizontal plate 6. When the drum 301 rotates at high speed, the transmission gear ring 801 at the bottom rotates and meshes with the linkage gear 803 to drive the installation shaft 802 to rotate. The installation shaft 802 rotates and drives the shaft 701 to rotate at high speed through the transmission cooperation of the synchronous wheel 804 and the synchronous belt 805. The rotation of the shaft 701 drives the two second spheres 7023 to rotate. When the second spheres 7023 rotate, centrifugal force will be generated to expand outward, thereby driving the second sliding sleeve 7024 to move. The displacement of the second sliding sleeve 7024 extends the extension plate 304 through the push rod 703, further improving the impact surface of the water flow impact plate 302, so that it can adapt to different water flow conditions and operation requirements, realize water flow regulation and enhancement, and at the same time, it can make secondary adjustments to the opening and closing structure 4. A transverse frame supporting the installation shaft 802 is fixed on the lower surface of the valve pipe 1. The installation shaft 802 is hinged to the transverse frame, and the transverse frame is located below the transmission gear ring 801.

[0047] In addition, when the water flow impacts the starting structure 3 and causes the drum 301 to rotate, the movement of the eccentric structure 702 will automatically adjust the position of the extension plate 304, thereby offsetting the external impact to a certain extent. Since the extension plate 304 is retractable and hinged to the eccentric structure 702, the valve body can adapt to different water flow conditions and operating requirements. This design enables the system to maintain high flexibility and response speed when facing water flow fluctuations or changes, thereby enhancing the stability of the valve body.

[0048] Specifically, the first sphere 403 and the second sphere 7023 both have a certain weight, the number of the second swing arm 7022, the second sphere 7023, the connecting rod 7026 and the push rod 703 on the eccentric structure 702 is two, and the two second swing arms 7022, the two connecting rods 7026 and the two push rods 703 are symmetrically arranged, the number of the eccentric structure 702 is two, and the two eccentric structures 702 are symmetrically distributed on the outer surface of the rotating shaft 701, wherein the four push rods 703 are respectively hinged to the opposite side of the two push plates 303 at one end away. The internal space of the rotating drum 301 is larger than the range of the second sphere 7023 when it is centrifugal, and the interior of the rotating drum 301 and the water flow impact plate 302 are both provided with sliding openings for the pushing work of the push rods 703.

[0049] like Figure 1 - Figure 8 As shown, the principle of the agricultural water-saving automatic irrigation valve provided in this embodiment is as follows:

[0050] When the present invention is used, the valve pipe 1 is first connected to the output end of the water delivery device through the flange. When the water delivery device delivers water into the valve pipe 1, the water flow will impact the water flow impact plate 302, driving the rotating drum 301 to rotate, and the rotating shaft 401 is driven to rotate through the gear assembly 5. The rotation of the rotating shaft 401 drives the two first spheres 403 to rotate. When the two first spheres 403 rotate, centrifugal force is generated to expand outward, so that the push rod 405 is used to drive the first installation sleeve 406 to move up. The first installation sleeve 406 moves up and drives the valve 2 to flip through the hinged cooperation of the connecting piece 407, thereby realizing automatic water delivery. In addition, when the rotating drum 301 When rotating at high speed, the transmission gear ring 801 at its bottom rotates and meshes with the linkage gear 803 to drive the installation shaft 802 to rotate. The rotation of the installation shaft 802 utilizes the transmission cooperation of the synchronous wheel 804 and the synchronous belt 805 to drive the rotating shaft 701 to rotate at high speed. The rotation of the rotating shaft 701 drives the two second spheres 7023 to rotate. When the second spheres 7023 rotate, centrifugal force is generated to expand outward, thereby driving the second sleeve 7024 to move. The displacement of the second sleeve 7024 extends the extension plate 304 through the push rod 703, further improving the impact surface of the water flow impact plate 302, so that it can adapt to different water flow conditions and operating requirements.
