[0002] In agricultural irrigation, electric ball valves play a crucial role as key components for controlling water flow. Currently, existing electric ball valves for irrigation are mainly used to control the on / off state and flow rate of water to meet the basic needs of farmland irrigation.

[0003] However, with the development of agricultural production and the increasing demands on irrigation systems, existing electric ball valves have gradually revealed some shortcomings in terms of function and structure.

[0004] Existing technologies are limited in function and can only achieve simple water flow control, which cannot meet diverse irrigation needs. For example, they cannot effectively flush and clean irrigation pipes or equipment, which can lead to water containing corrosive substances such as fertilizers remaining in the pipes and valves. Over time, this accumulation will corrode the valves and pipes and shorten the service life of the equipment. Utility Model Content

It also has a flushing function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an electric ball valve for irrigation, and an electric ball valve structure for irrigation, including an electric ball valve housing, both ends of which are fixedly connected to a first connecting flange, a spherical groove being formed inside the electric ball valve housing, a fixing plate being fixedly connected to the outer wall of the electric ball valve housing, a support frame being fixedly connected to the top of the fixing plate, and an indirect gate opening mechanism being fixedly connected to the top of the support frame; the indirect gate opening mechanism includes a motor, a push block being fixedly connected to the output end of the motor, a first transmission rod being in contact with the outer wall of the push block, a first rotating shaft being rotatably connected to the outer wall of the first transmission rod, a spring being fixedly connected to the bottom of the first transmission rod via a sleeve, a fixing frame being fixedly connected to one end of the spring, a second transmission rod being rotatably connected to the outer surface of the first transmission rod via a shaft, and a sliding plate sluice gate being rotatably connected to the outer surface of the second transmission rod via a shaft.

[0007] Preferably, the output end of the motor is fixedly connected to a three-way ball valve, the outer wall of which has three drainage holes and is connected to two first connecting flanges, one of which is movably connected to a flushing mechanism.

Detailed Implementation

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Please see attached Figure 1 - Appendix Figure 6As shown, this utility model provides a technical solution: an electric ball valve structure for irrigation, including an electric ball valve housing 1, with a first connecting flange 11 fixedly connected to both ends of the electric ball valve housing 1, a spherical groove 12 opened inside the electric ball valve housing 1, a fixing plate 13 fixedly connected to the outer wall of the electric ball valve housing 1, a support frame 14 fixedly connected to the top of the fixing plate 13, and an indirect gate opening mechanism 4 fixedly connected to the top of the support frame 14; the indirect gate opening mechanism 4 includes a motor 401, a push block 402 fixedly connected to the output end of the motor 401, a first transmission rod 403 in contact with the outer wall of the push block 402, a first rotating shaft 405 rotatably connected to the outer wall of the first transmission rod 403, a spring 404 fixedly connected to the bottom of the first transmission rod 403 through a sleeve, a fixing frame 406 fixedly connected to one end of the spring 404, and a second shaft 405 rotatably connected to the outer surface of the first transmission rod 403 through a shaft. The outer surface of the transmission rod 407 is rotatably connected to the slide gate 409 via a shaft. The electric ball valve housing 1 is the foundation of the entire device, providing a stable installation space and protective barrier for the internal components, preventing damage to the internal structure from external factors. The first connecting flange 11 facilitates connection with external irrigation pipes, ensuring that water can smoothly enter and exit the device. It is the inlet and outlet channel for the water flow of the entire irrigation system. The spherical groove 12 provides space for the rotation of the three-way ball valve 5, allowing the three-way ball valve 5 to flexibly switch between different water flow channels, realizing the switching between main channel irrigation and flushing functions. The fixing plate 13 plays a connecting and supporting role, fixing the support frame 14 to the outer wall of the electric ball valve housing 1, providing a stable installation position for the indirect gate opening mechanism 4. The support frame 14 further ensures that the indirect gate opening mechanism 4 is in a suitable working position, ensuring that it can accurately control the action of the slide gate 409.

[0025] Please see attached Figure 1 - Appendix Figure 6As shown, a three-way ball valve 5 is fixedly connected to the output end of the motor 401. The outer wall of the three-way ball valve 5 has three drainage holes, which are connected to two first connecting flanges 11. One of these flanges is connected to a flushing mechanism 3. The motor 401 acts as a power source; after starting, its output end drives the push block 402 to perform circular motion. During this motion, the push block 402 contacts the first transmission rod 403 and pushes it to rotate around the first rotating shaft 405. The spring 404 connected to the bottom of the first transmission rod 403 is stretched or compressed when the first transmission rod 403 rotates. When the motor 401 stops or changes its rotation direction... When moving in the direction of motion, the elastic force of the spring 404 can return the first transmission rod 403 to its initial position, which plays a role in buffering and resetting, and at the same time ensures the smoothness of the transmission process. The first transmission rod 403 is connected to the second transmission rod 407 through a shaft. The rotation of the first transmission rod 403 will drive the second transmission rod 407 to move. The second rotating shaft 408 on the second transmission rod 407 is connected to the sliding sluice gate 409, thereby transmitting the power of the motor 401 to the sliding sluice gate 409, realizing the up and down movement of the sliding sluice gate 409, and thus controlling the opening and closing of the water flow and the flow rate in the connecting pipe 304.

[0026] Please see attached Figure 1 - Appendix Figure 6 As shown, the flushing mechanism 3 includes a second connecting flange 301. A support plate 302 is fixedly connected to the outer wall of the second connecting flange 301. A support column 303 is fixedly connected to the top of the support plate 302. A connecting pipe 304 is fixedly connected to the outer wall of the second connecting flange 301. A three-way ball valve 5 is connected to the output end of the motor 401. When the motor 401 rotates, it drives the three-way ball valve 5 to rotate in the spherical groove 12. The three drainage holes on the outer wall of the three-way ball valve 5 perform different functions. Two of the drainage holes are connected to the first connecting flange 11. By rotating the three-way ball valve 5, the connection state between these two holes and the first connecting flange 11 can be changed, thereby controlling the direction and flow rate of the main channel water flow and realizing the conventional irrigation function. The other drainage hole is movably connected to the flushing mechanism 3. When flushing operation is required, the motor 401 drives the three-way ball valve 5 to rotate, so that the drainage hole is connected to the flushing mechanism 3, and some water flow is introduced into the flushing mechanism 3.

[0027] Please see attached Figure 1 - Appendix Figure 6As shown, the top of the connecting pipe 304 is fixedly connected to the transmission pipe 6, and the outer wall of the transmission pipe 6 is fixedly connected to the distribution plate 7. Multiple high-pressure nozzles 8 are fixedly connected to the outer surface of the distribution plate 7. When the three-way ball valve 5 introduces water into the flushing mechanism 3, the water first enters the connecting pipe 304 through the second connecting flange 301. The second connecting flange 301 ensures a tight connection between the three-way ball valve 5 and the flushing mechanism 3 and smooth water transmission. The support plate 302 and the support column 303 provide stable structural support for the entire flushing mechanism, ensuring the stability of each component under the impact of water flow. The connecting pipe 304 transmits the water to the transmission pipe 6, and the transmission pipe 6 then guides the water to the distribution plate 7. The distribution plate 7 evenly distributes the water to the multiple high-pressure nozzles 8. The high-pressure nozzles 8 spray the water in a high-pressure form to flush the soil in the farmland that may contain fertilizer, preventing corrosive substances such as fertilizer from adhering to the machine valves, thus playing the role of a protective device.

[0028] Please see attached Figure 1 - Appendix Figure 6 As shown, the outer wall of the three-way ball valve 5 and the inner wall of the spherical groove 12 are movably fitted together. The top of the support frame 14 and the bottom of the motor 401 are fixedly connected. The movable fit between the outer wall of the three-way ball valve 5 and the inner wall of the spherical groove 12 allows the three-way ball valve 5 to rotate flexibly within the spherical groove 12, enabling the switching of different water flow channels and ensuring the smooth switching of irrigation and flushing functions in the main channel. The top of the support frame 14 fixes the bottom of the motor 401, providing a stable installation foundation for the motor 401 and ensuring that the motor 401 remains stable during operation, reliably providing power to the indirect gate opening mechanism 4 and the three-way ball valve 5.

[0029] Please see attached Figure 1 - Appendix Figure 6 As shown, the top of the second connecting flange 301 is fixedly connected to the bottom of the fixing frame 406, the top of the support column 303 is fixedly connected to the bottom of the first rotating shaft 405, and the top of the second connecting flange 301 is fixedly connected to the bottom of the fixing frame 406, structurally linking the flushing mechanism 3 and the indirect gate opening mechanism 4, enabling the two mechanisms to work together. The top of the support column 303 is connected to the bottom of the first rotating shaft 405, providing support for the first rotating shaft 405 and ensuring the stability of the first transmission rod 403 during rotation, thereby ensuring that the indirect gate opening mechanism 4 can accurately control the action of the sliding gate 409. The sliding gate 409 is connected to the connecting pipe 304, and the sliding gate 409 is movably inserted into the connecting pipe 304. The movement of the sliding gate 409 is controlled by the indirect gate opening mechanism 4 to realize the control of the flow of water in the connecting pipe 304. When the sliding gate 409 is open, the water flow can enter the flushing mechanism 3 for flushing operation; when the sliding gate 409 is closed, the flushing function stops.

[0030] Working Principle: Working Principle of Each Part: Indirect Gate Opening Mechanism Working Principle Power Input: After the motor 401 starts, its output end drives the push block 402 to perform circular motion. The motor 401 serves as the power source for the entire indirect gate opening mechanism, providing driving force for subsequent actions. Force Transmission and Conversion: The outer wall of the push block 402 contacts the first transmission rod 403. The circular motion of the push block 402 drives the first transmission rod 403 to rotate around the first rotating shaft 405. The spring 404, which is fixedly connected to the bottom of the first transmission rod 403 through a sleeve, plays a role in buffering and resetting during the rotation of the first transmission rod 403. When the push block 402 pushes the first transmission rod 403 to rotate, the spring 404 will be stretched or compressed; when the push block 402 no longer applies thrust, the elastic force of the spring 404 causes the first transmission rod 403 to return to its initial position. Gate Control: The outer surface of the first transmission rod 403 is rotatably connected to the second transmission rod 407 through a shaft. When the first transmission rod 403 rotates, it will drive the second transmission rod 407 to move. The second rotating shaft 408, fixedly connected to the outer surface of the second transmission rod 407, is rotatably connected to the sliding gate 409, thereby converting the rotation of the first transmission rod 403 into the linear motion of the sliding gate 409. The sliding gate 409 is movably inserted inside the connecting pipe 304, and its linear motion controls the flow of water in the connecting pipe 304 or regulates the flow rate. The three-way ball valve operates on the principle that the output end of the motor 401 is fixedly connected to the three-way ball valve 5. The rotation of the motor 401 drives the three-way ball valve 5 to rotate within the spherical groove 12 inside the electric ball valve housing 1. The outer wall of the three-way ball valve 5 has three drainage holes, two of which are connected to the first connecting flanges 11 at both ends of the electric ball valve housing 1, used to control the water flow in the main channel. By rotating the three-way ball valve 5, the connection state between these two drainage holes and the first connecting flanges 11 can be changed, thereby realizing the control of the flow and direction of the main channel water flow. Another drain hole of the three-way ball valve 5 is movably connected to the flushing mechanism 3. When flushing is required, the three-way ball valve 5 is rotated to connect the drain hole to the flushing mechanism 3, allowing some water to flow into the flushing mechanism 3. The flushing mechanism works as follows: When the three-way ball valve 5 introduces water into the flushing mechanism 3, the water flows through the second connecting flange 301 into the connecting pipe 304. The top of the connecting pipe 304 is fixed with a connecting transmission pipe 6, through which the water flows into the distribution plate 7. The distribution plate 7 evenly distributes the water flow to multiple high-pressure nozzles 8, which spray the water at high pressure to achieve flushing or fine irrigation of the irrigation area. When the main channel needs to be opened for irrigation, the motor 401 drives the three-way ball valve 5 to rotate, opening the drain hole connected to the first connecting flange 11. Simultaneously, the indirect gate opening mechanism controls the sliding gate 409 to open, allowing water to enter from one end of the first connecting flange 11, pass through the electric ball valve housing 1, and flow out from the other end of the first connecting flange 11 for irrigation.When flushing is required, motor 401 drives three-way ball valve 5 to rotate, opening the drainage hole connected to flushing mechanism 3. Water flows into flushing mechanism 3 and is sprayed out through high-pressure nozzle 8 to achieve the flushing function. At the same time, the opening degree of sliding gate 409 can be adjusted through indirect gate opening mechanism to control the amount of water entering flushing mechanism 3 as needed.
