Description

Technical Field

[0001] The present invention relates to the technical field of irrigation. Specifically, it relates to a water-controlled automatic interactive three-way irrigation valve and a non-electric automatic irrigation system. Background Art

[0002] In aspects such as urban greening, desert transformation, soilless cultivation, and agricultural production, the application of irrigation technologies such as spraying and drip irrigation is essential.

[0003] However, at present, most irrigation is manually controlled. Even in places where automated irrigation is adopted under permitted conditions, it must be in an environment with electricity. This is because existing automated irrigation is mostly designed based on intelligent control electric irrigation valves, which require long-term power-on operation, have a short service life, and involve the processing of control signals. The system is relatively complex, with high costs and difficult maintenance.

[0004] Furthermore, it is very inconvenient to use electricity in places such as urban greening, desert transformation, and remote fields in agricultural production.

[0005] Therefore, there is an urgent need to design a water valve and a system that can achieve automatic irrigation without power supply in an environment of long-term unattended operation. Summary of the Invention

[0006] The purpose of the present invention is to address the deficiencies of the prior art, and thus provide a water-controlled automatic interactive three-way irrigation valve and a non-electric automatic irrigation system.

[0007] To achieve the above purpose, the technical solution adopted by the present invention is: a water-controlled automatic interactive three-way irrigation valve, including a three-way composed of a main water inlet pipe and two water outlet branch pipes, and a water-full self-stop valve is provided on each of the two water outlet branch pipes; The bottom pressure relief hole of the water-full self-stop valve is connected to the water outlet through a soft catheter with a rubber cap, and the rubber cap covers the bottom pressure relief hole of the water-full self-stop valve; A plugging mechanism is provided below the two water-full self-stop valves. The plugging mechanism can interactively squeeze the two rubber caps to interactively block the bottom pressure relief holes of the two water-full self-stop valves, so as to interactively open and close the two water-full self-stop valves.

[0008] Based on the above, the plugging mechanism includes a pressure - applying lever and a driving component. The pressure - applying lever is arranged below the two water - full self - stopping valves, and the vertical projection of the pressure - applying lever coincides with the connection line of the bottom pressure - relief holes of the two water - full self - stopping valves. The central fulcrum of the pressure - applying lever is arranged in the middle of the bottom pressure - relief holes of the two water - full self - stopping valves. Two pressure - applying plugs are symmetrically arranged on the pressure - applying lever with respect to the central fulcrum. The two pressure - applying plugs respectively correspond to and are vertically aligned with the two rubber caps one by one. The driving component can drive the pressure - applying lever to reciprocally rotate up and down around the central fulcrum, so that the two pressure - applying plugs respectively correspond to and alternately squeeze the two rubber caps, thereby causing the two rubber caps to be deformed under pressure and alternately block the bottom pressure - relief holes of the two water - full self - stopping valves, and enabling the two water - full self - stopping valves to be alternately opened and closed; Initially, the pressure - applying lever is inclined, so that one pressure - applying plug squeezes a corresponding rubber cap, thereby closing a corresponding water - full self - stopping valve, and the other pressure - applying plug does not contact the corresponding other rubber cap, so that the corresponding other water - full self - stopping valve is opened.

[0009] Based on the above, the driving component includes a bearing frame, a weight - biased water box and a counterweight. The two water outlet pipes are installed on the bearing frame. The upper end of the weight - biased water box is open. The weight - biased water box is rotatably installed on the bearing frame up and down through a bracket and is located directly below the pressure - applying lever. The rotation fulcrum of the weight - biased water box connected to the bracket is located at an eccentric position of the weight - biased water box. The counterweight is arranged on the side of the weight - biased water box closer to the rotation fulcrum, which can keep the weight - biased water box horizontal within a certain water volume range. A connecting rod is connected between the weight - biased water box and the pressure - applying lever. When the weight - biased water box flips, it can drive the pressure - applying lever to rotate through the connecting rod; At the water outlet of the initially opened water - full self - stopping valve, a first water outlet valve with adjustable opening to control the dripping speed is installed. The first water outlet valve can drip water into the weight - biased water box. A second water outlet valve with adjustable opening to control the dripping speed is arranged at the lower part of the side of the weight - biased water box farther from the rotation fulcrum. The second water outlet valve can make the water in the weight - biased water box drip out. The dripping speed of the first water outlet valve is greater than that of the second water outlet valve. By adjusting the opening degrees of the first water outlet valve and the second water outlet valve, the water volume increasing speed in the weight - biased water box can be controlled. Furthermore, it is possible to achieve timed control similar to dripping, so that the weight - biased water box flips due to the increase in water volume from the horizontal state, and the pressure - applying lever rotates in the opposite direction to an opposite angle of inclination.

[0010] Based on the above, the driving component includes a bearing box body and a floating ball. The upper end of the bearing box body is open. The bearing box body is installed at the lower part of the two water outlet branch pipes and corresponds to the two water-full self-closing valves up and down. The two water-full self-closing valves are placed in the upper port of the bearing box body. There is water in the bearing box body and the water level is lower than the pressing lever. The floating ball floats on the water surface in the bearing box body and is connected to the pressing lever through a traction rod. When the floating ball moves up and down with the water level, it can drive the pressing lever to rotate through the traction rod. At the water outlet of the initially opened water-full self-closing valve, a first water outlet valve with adjustable opening to control the dripping speed is installed. The first water outlet valve can drip water into the bearing box body. A second water outlet valve with adjustable opening to control the dripping speed is arranged at the lower part of one side of the bearing box body. The second water outlet valve can make the water in the bearing box body drip out. The dripping speed of the first water outlet valve is greater than that of the second water outlet valve. By adjusting the opening degrees of the first water outlet valve and the second water outlet valve, the rising speed of the water level in the heavy water box can be controlled. Furthermore, it is possible to achieve timed control similar to dripping to make the floating ball rise to a certain height, so that the pressing lever rotates in the opposite direction to an inclined angle.

[0011] Based on the above, first magnet blocks are arranged at both ends of the pressing lever, and second magnet blocks are arranged at the bottoms of the two water-full self-closing valves. The two first magnet blocks and the two second magnet blocks correspond to each other up and down one by one and can be adsorbed and matched.

[0012] A non-electric automatic irrigation system includes a plurality of three-way valves connected in sequence, and the three-way valves adopt the water-controlled automatic interactive three-way irrigation valve as described above.

[0013] The present invention has prominent substantial features and remarkable progress compared with the prior art. Specifically, the present invention installs the water-full self-closing valves on the two water outlet branch pipes forming the three-way. The pressing lever is used to alternately squeeze the rubber caps at the pressure relief holes at the bottoms of the corresponding two water-full self-closing valves, so as to alternately block the pressure relief holes at the bottoms of the two water-full self-closing valves, and then the two water-full self-closing valves can be alternately opened and closed. The pressing lever is driven by a heavy water box or a floating ball, that is, gravity or buoyancy is utilized, and all are controlled by water, completely getting rid of the bondage of the traditional intelligent control electric irrigation valve relying on electricity to work. It can achieve automatic control, can be used in outdoor non-electric environments, and can be suitable for unattended environments, saving worry and labor. Compared with the existing intelligent control electric irrigation valve, the water-controlled automatic interactive three-way irrigation valve of the present invention has a simple structure, stable performance, low cost, convenient use, does not need to consider the power supply problem, has no electronic components relying on electricity, has a long service life, and is easy to maintain.

[0014] Further, a power-free automatic irrigation system is provided, which uses the water-controlled automatic interactive three-way irrigation valve. In this way, the irrigation system without power constraints can achieve automatic irrigation in an unattended environment throughout the year, with low cost, saving time, labor and worry, and can be widely applied in urban greening, desert transformation, agricultural planting and other aspects.

[0023] The technical solutions of the present invention will be further described in detail below through specific embodiments.

[0024] Embodiment 1 As Figure 1 and Figure 2 shown, the water-controlled automatic interactive three-way irrigation valve includes a three-way composed of a main inlet pipe 1 and two sub-outlet pipes 2, and a water full self-stop valve 3 is provided on each of the two sub-outlet pipes 2; The bottom pressure relief hole of the water full self-stop valve 3 is communicated with the water outlet through a flexible conduit with a rubber cap 4, and the rubber cap 4 covers the bottom pressure relief hole of the water full self-stop valve 3; A plugging mechanism 5 is arranged below the two water full self-stop valves 3. The plugging mechanism 5 can alternately squeeze the two rubber caps 4 to alternately block the bottom pressure relief holes of the two water full self-stop valves 3, so as to alternately open and close the two water full self-stop valves 3.

[0025] The plugging mechanism 5 includes a pressure lever 6 and a driving assembly. The pressure lever 6 is arranged below the two water full self-stop valves 3 and coincides with the vertical projection of the connection line of the bottom pressure relief holes of the two water full self-stop valves 3. The central fulcrum of the pressure lever 6 is arranged in the middle of the bottom pressure relief holes of the two water full self-stop valves 3. Two pressure plugs 7 are symmetrically arranged on the pressure lever 6 with respect to the central fulcrum. The two pressure plugs 7 respectively correspond to the two rubber caps 4 one by one up and down. The driving assembly can drive the pressure lever 6 to rotate up and down reciprocally around the central fulcrum, so that the two pressure plugs 7 respectively correspond to alternately squeeze the two rubber caps 4, so that the two rubber caps 4 are deformed under pressure to alternately block the bottom pressure relief holes of the two water full self-stop valves 3, and the two water full self-stop valves 3 are alternately opened and closed; When the pressure lever 6 is initially inclined, one pressure plug 7 can squeeze a corresponding rubber cap 4, so as to close a corresponding water full self-stop valve 3, and the other pressure plug 7 does not contact a corresponding other rubber cap 4, so as to open a corresponding other water full self-stop valve 3.

[0026] The driving assembly includes a carrier 8, a heavy water box 9 and a counterweight 10. Two water outlet pipes 2 are installed on the carrier 8. The upper end of the heavy water box 9 is open. The heavy water box 9 is rotatably installed on the carrier 8 up and down through a bracket 11 and is located directly below the pressure lever 6. The rotation fulcrum of the heavy water box 9 connected to the bracket 11 is located at an eccentric position of the heavy water box 9. The counterweight 10 is arranged on the side of the heavy water box 9 closer to the rotation fulcrum, which can keep the heavy water box 9 horizontal within a certain water volume range. A connecting rod 22 is connected between the heavy water box 9 and the pressure lever 6. When the heavy water box 9 flips, it can drive the pressure lever 6 to rotate through the connecting rod 22. At the water outlet of the initially opened water full self-stop valve 3, a first water outlet valve 12 with adjustable opening to control the dripping speed is installed. The first water outlet valve 12 can drip water into the heavy water box 9. A second water outlet valve 13 with adjustable opening to control the dripping speed is arranged at the lower part of the side of the heavy water box 9 farther from the rotation fulcrum. The second water outlet valve 13 can make the water in the heavy water box 9 drip out. The dripping speed of the first water outlet valve 12 is greater than that of the second water outlet valve 13. By adjusting the opening degrees of the first water outlet valve 12 and the second water outlet valve 13, the water volume increasing speed in the heavy water box 9 can be controlled. Furthermore, it can be realized to control the heavy water box 9 to flip from the horizontal state due to the increase of water volume like dripping at regular intervals, so that the pressure lever 6 rotates in the opposite direction to an inclined state at the opposite angle.

[0027] In this embodiment, gravity is utilized to drive the rotation of the pressure lever 6, and further to alternately open and close the two water full self-stop valves 3.

[0028] The specific working principle is as follows: Water enters through the main water inlet pipeline. The water outlet branch pipe 2 where the initially opened water-full self-stop valve 3 is located conducts water discharge, and the water outlet branch pipe 2 where the initially closed water-full self-stop valve 3 is located cuts off water supply. The heavy water box 9 remains horizontal under the action of the counterweight 10. The first water outlet valve 12 on the initially opened water-full self-stop valve 3 drips water into the heavy water box 9. At the same time, the second water outlet valve 13 drips out the water in the heavy water box 9. Adjust the opening degrees of the first water outlet valve 12 and the second water outlet valve 13 to gradually increase the water volume in the heavy water box 9. When the water volume in the heavy water box 9 reaches or exceeds a certain value, the heavy water box 9 rotates and tilts around the rotation fulcrum under the action of the gravity of water. The side of the heavy water box 9 farther from the rotation fulcrum flips downward. Then, the heavy water box 9 drives the pressure lever 6 to rotate in the reverse direction to an opposite angle of inclination through the connecting rod 22, so that a group of the pressure plugs 7 and the rubber caps 4 that were initially in extrusion contact are separated, and the bottom pressure relief hole of the initially blocked water-full self-stop valve 3 is opened, thereby converting the initially closed water-full self-stop valve 3 to an open state. On the contrary, a group of the pressure plugs 7 and the rubber caps 4 that were initially separated and not in contact start to be in extrusion contact, the bottom pressure relief hole of the initially unblocked water-full self-stop valve 3 is blocked, and the initially opened water-full self-stop valve 3 is converted to a closed state. Then, the first water outlet valve 12 stops dripping water, while the second water outlet valve 13 continues to drip water. When the water volume in the heavy water box 9 decreases to a certain range, the heavy water box 9 will re-flip to the horizontal state under the action of the counterweight 10, and then the pressure lever 6 rotates forward to the initial inclined state, so that the two pressure plugs 7 return to the initial state. Similarly, the two water-full self-stop valves 3 also return to the initial state. In this way, the two water-full self-stop valves 3 can be alternately opened and closed, the two water outlet branch pipes 2 can be alternately connected and disconnected, and the alternate opening and closing process of the two water-full self-stop valves 3 is completely controlled by water, which can achieve automatic control, can be used in an outdoor environment without electricity, and can be applied to an unattended environment, saving worry and labor. Compared with the existing intelligent control electric irrigation valve, the water-controlled automatic alternate three-way irrigation valve of the present invention has a simple structure, stable performance, low cost, convenient use, does not need to consider the power supply problem, has no electronic components relying on electricity, has a long service life, and is simple to maintain.

[0029] The water-controlled automatic alternate three-way irrigation valve of the present invention can be set with multiple interaction cycles (from dozens of seconds to hundreds of hours, controlled by the opening degrees of the first water outlet valve 12 and the second water outlet valve 13).

[0030] Embodiment 2 Different from Embodiment 1, as Figure 3As shown, the drive assembly includes a bearing box body 14 and a floating ball 15. The upper end of the bearing box body 14 is open. The bearing box body 14 is installed at the lower part of the two water outlet branch pipes 2 and corresponds to the two water-full self-closing valves 3 up and down. The two water-full self-closing valves 3 are placed in the upper port of the bearing box body 14. There is water in the bearing box body 14 and the water level is lower than the pressure lever 6. The floating ball 15 floats on the water surface in the bearing box body 14 and is connected to the pressure lever 6 through a traction rod 16. When the floating ball 15 moves up and down with the water level, it can drive the pressure lever 6 to rotate through the traction rod 16. At the water outlet of the initially opened water-full self-closing valve 3, a first water outlet valve 12 with adjustable opening to control the dripping speed is installed. The first water outlet valve 12 can drip water into the bearing box body 14. At the lower part of one side of the bearing box body 14, a second water outlet valve 13 with adjustable opening to control the dripping speed is provided. The second water outlet valve 13 can make the water in the bearing box body 14 drip out. The dripping speed of the first water outlet valve 12 is greater than that of the second water outlet valve 13. By adjusting the opening degrees of the first water outlet valve 12 and the second water outlet valve 13, the rising speed of the water level in the heavy water box 9 can be controlled. Furthermore, it can be realized to control the floating ball 15 to rise to a certain height at a fixed time similar to dripping, so that the pressure lever 6 rotates in the opposite direction to an opposite inclination angle.

[0031] In this embodiment, the buoyancy is utilized to drive the rotation of the pressure lever 6, and further to alternately open and close the two water-full self-closing valves 3.

[0032] The specific working principle is as follows: Water enters through the main water inlet pipeline. The water outlet branch pipe 2 where the initially opened water full self-closing valve 3 is located conducts water discharge, and the water outlet branch pipe 2 where the initially closed water full self-closing valve 3 is located cuts off water supply. The floating ball 15 is at a low water level in the bearing box body 14. The first water outlet valve 12 on the initially opened water full self-closing valve 3 drips water into the bearing box body 14. At the same time, the second water outlet valve 13 drips water out of the bearing box body 14. Adjust the opening degrees of the first water outlet valve 12 and the second water outlet valve 13 to gradually raise the water level in the bearing box body 14. When the water level in the bearing box body 14 reaches or exceeds a certain height, the floating ball 15 rises under the buoyancy of water. Then, the floating ball 15 drives the pressure lever 6 to rotate in the reverse direction to an inclined state at the opposite angle through the traction rod 16, so that a group of the pressure plugs 7 and the rubber caps 4 that were initially in extrusion contact are separated, and the bottom pressure relief hole of the initially blocked water full self-closing valve 3 is opened. Thus, the initially closed water full self-closing valve 3 is turned into an open state. On the contrary, a group of the pressure plugs 7 and the rubber caps 4 that were initially separated and not in contact start to be in extrusion contact, and the bottom pressure relief hole of the initially unblocked water full self-closing valve 3 is blocked. The initially opened water full self-closing valve 3 is turned into a closed state. Then, the first water outlet valve 12 stops dripping water, while the second water outlet valve 13 continues to drip water. When the water level in the bearing box body 14 drops to the initial position, the floating ball 15 drops back to the low water level again. Then, the pressure lever 6 rotates forward to the initial inclined state, and the two pressure plugs 7 return to the initial state. Similarly, the two water full self-closing valves 3 also return to the initial state. In this way, the two water full self-closing valves 3 can be alternately opened and closed, and the two water outlet branch pipes 2 can be alternately connected and disconnected; the technical effects are the same as those in Embodiment 1 and will not be elaborated here.

[0033] It should be noted here that in other embodiments, in addition to using gravity and buoyancy to drive the rotation of the pressure lever 6, the driving component can also drive the rotation of the pressure lever 6 through various forces that can generate actions such as water pressure in the pipeline and electromagnetic induction. That is, all methods that can drive the rotation of the pressure lever 6 can be applied to achieve the same effects as those in Embodiments 1 and 2.

[0034] Embodiment 3 Such as Figure 2 and Figure 3As shown, on the basis of Embodiment 1 or Embodiment 2, in order to improve the reliability of the rotation action of the pressure - applying lever 6 and ensure that the pressure - applying plug 7 squeezes the corresponding rubber cap 4 more tightly, first magnet blocks 17 are arranged at both ends of the pressure - applying lever 6, and second magnet blocks 18 are arranged at the bottoms of the two water - full self - stopping valves 3. The two first magnet blocks 17 and the two second magnet blocks 18 are in one - to - one correspondence up and down and can be adsorbed and matched. When the pressure - applying lever 6 rotates, when one end of the pressure - applying lever 6 gradually approaches a corresponding water - full self - stopping valve 3, the first magnet block 17 at this end will attract the corresponding second magnet block 18 above it, so that the pressure - applying lever 6 can rotate to the position quickly and more reliably.

[0035] Embodiment 4 Adopting the above - mentioned technology, as Figure 4 shown, this embodiment also provides a non - electric automatic irrigation system, which includes a plurality of three - way valves connected in sequence, and the three - way valves adopt the water - controlled automatic interactive three - way irrigation valve as described above.

[0036] During specific use, each of the water - controlled automatic interactive three - way irrigation valves is arranged in the area to be irrigated according to the irrigation sequence. The inlet main pipeline 1 of the first water - controlled automatic interactive three - way irrigation valve is connected to the water supply pipeline 19 for irrigation. Irrigation devices 20 are installed on the initially - conducting water - outlet sub - pipelines 2 of each water - controlled automatic interactive three - way irrigation valve, and the initially - disconnected water - outlet sub - pipelines 2 are connected to the inlet main pipeline 1 of the next water - controlled automatic interactive three - way irrigation valve through the water - conveying pipeline 21. The initially - disconnected water - outlet sub - pipeline 2 of the last water - controlled automatic interactive three - way irrigation valve is directly blocked or connected to the downstream pipeline.

[0037] During actual use, water flows through the main water inlet pipe 1 of the first water-controlled automatic interactive three-way irrigation valve, and water is discharged from the initially-conducted water outlet branch pipe 2 of the first water-controlled automatic interactive three-way irrigation valve. At this point, the irrigation device 20 is supplied with water for irrigation. Referring to the usage principles in Embodiment 1 or Embodiment 2, when a certain period of time has passed, the initially-conducted water outlet branch pipe 2 of the first water-controlled automatic interactive three-way irrigation valve switches to a disconnected state, and the irrigation device 20 here stops receiving water and halts irrigation. The initially-disconnected water outlet branch pipe 2 of the first water-controlled automatic interactive three-way irrigation valve switches to a conductive state, starts discharging water, and supplies water to the second water-controlled automatic interactive three-way irrigation valve through the water delivery pipe 21. Then, the irrigation device 20 installed on the second water-controlled automatic interactive three-way irrigation valve starts to be supplied with water for irrigation. In this way, the irrigation work for each area that needs to be irrigated can be completed in sequence, ensuring that the water pressure and water output during irrigation of each irrigation device are basically the same, while also reducing water resource waste. Each set of such an irrigation system can be connected in series with different numbers of the water-controlled automatic interactive three-way irrigation valves according to actual needs. Such an irrigation system that is not restricted by power can achieve automatic irrigation in an unattended environment throughout the year, with low costs, saving time, labor, and worry, and can be widely applied in urban greening, desert transformation, agricultural planting, etc.

[0038] Moreover, the water-controlled automatic interactive three-way irrigation valve in this non-electric automated irrigation system controls the water discharge time of each corresponding irrigation device 20 to be basically synchronized with the soil moisture content. It is also possible to manually adjust the opening degrees of the first water outlet valve 12 and the second water outlet valve 13 according to the water demand characteristics of the crops to adjust the time (cycle) of the interactive on-off of the two water outlet branch pipes 2, that is, to adjust the water discharge and cut-off times of the irrigation device 20. The soil moisture content is related to the weather. When it rains, rainwater will enter the heavy water box 9 in Embodiment 1 or the bearing box body 14 in Embodiment 2, causing the water volume in the heavy water box 9 or the bearing box body 14 to increase much faster than usual. As a result, the heavy water box 9 can be flipped earlier or the floating ball 15 can rise to a certain height earlier, causing the pressure lever 6 to rotate to the opposite angle of inclination earlier, and then closing the water full self-stop valve 3 on the water outlet branch pipe 2 where the irrigation device 20 is located in advance, thereby reducing the irrigation time or even not irrigating at all; during high-temperature and drought periods, it is exactly the opposite of when it rains, which will cause the evaporation rate of the water in the heavy water box 9 or the bearing box body 14 to accelerate, resulting in the water volume in the heavy water box 9 or the bearing box body 14 increasing much slower than usual, causing the heavy water box 9 to be flipped later or the floating ball 15 to rise to a certain height later, and thus increasing the irrigation time.

[0039] It should be noted that the water full self-stop valve 3 is a floating ball type water level control valve, which is an existing device and can be purchased on the market. During use, simply block or open the bottom pressure relief hole of the water full self-stop valve 3 to achieve the opening and closing of the water full self-stop valve 3. See Figure 5 、Figure 6 and Figure 7 As shown in the figure, the bottom pressure relief hole of the water-filled automatic stop valve 3 is shown. The original float and the bottom shell on which the float is installed of the float-type water level control valve are removed, and the bottom of the valve body structure is set upward. The water-filled automatic stop valve 3 of the present invention is a valve body structure obtained by removing the float, the bottom shell on which the float is installed, and the lever mechanism of the purchased float-type water level control valve, which is equivalent to Figure 5 , Figure 6 and Figure 7 The valve body structure obtained by removing the lever mechanism used to block the bottom pressure relief hole of the water-filled automatic stop valve 3 is the valve body structure of the float type water level control valve, which is a conventional design, and the specific structure and working principle are not repeated here.

[0040] In practical applications, the weighted water box 9 and the float 15 do not necessarily have to be arranged below the two water-full automatic stop valves 3. The weighted water box 9 and the float 15 can be arranged at any position above, below, left or right of the two water-full automatic stop valves 3.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.

The water-controlled automatic interactive three-way irrigation valve according to claim 2, characterized in that: The driving component includes a bearing frame, a heavy water box and a counterweight. The two water outlet branch pipes are installed on the bearing frame. The upper end of the heavy water box is open. The heavy water box is rotatably installed on the bearing frame up and down through a bracket and is located directly below the pressure application lever. The rotation fulcrum of the heavy water box connected to the bracket is located at an eccentric position of the heavy water box. The counterweight is arranged on the side of the heavy water box closer to the rotation fulcrum to keep the heavy water box horizontal within a certain water volume range. A connecting rod is connected between the heavy water box and the pressure application lever. When the heavy water box flips, it can drive the pressure application lever to rotate through the connecting rod; A first water outlet valve with adjustable opening to control the dripping speed is installed at the water outlet of the initially opened water full self-stop valve. The first water outlet valve can drip water into the heavy water box. A second water outlet valve with adjustable opening to control the dripping speed is arranged at the lower part of the side of the heavy water box farther from the rotation fulcrum. The second water outlet valve can make the water in the heavy water box drip out. The dripping speed of the first water outlet valve is greater than that of the second water outlet valve. By adjusting the opening degrees of the first water outlet valve and the second water outlet valve, the water volume increase speed in the heavy water box can be controlled, and thus it can be realized to periodically control the heavy water box to flip from the horizontal state due to the increase of water volume like dripping, so that the pressure application lever rotates in the opposite direction to an opposite angle of inclination.

4. The water control automatic interactive three-way irrigation valve according to claim 2, wherein: The driving assembly includes a bearing box body and a floating ball. The upper end of the bearing box body is open. The bearing box body is installed at the lower part of the two water outlet branch pipes and corresponds to the two water-full self-stop valves up and down. The two water-full self-stop valves are placed in the upper port of the bearing box body. There is water in the bearing box body and the water level is lower than the pressing lever. The floating ball floats on the water surface in the bearing box body and is connected to the pressing lever through a traction rod. When the floating ball moves up and down with the water level, it can drive the pressing lever to rotate through the traction rod. A first water outlet valve with adjustable opening degree to control the dripping speed is installed at the water outlet of the initially opened water-full self-stop valve. The first water outlet valve can drip water into the bearing box body. A second water outlet valve with adjustable opening degree to control the dripping speed is arranged at the lower part of one side of the bearing box body. The second water outlet valve can make the water in the bearing box body drip out. The dripping speed of the first water outlet valve is greater than that of the second water outlet valve. By adjusting the opening degrees of the first water outlet valve and the second water outlet valve, the rising speed of the water level in the heavy water box can be controlled. Furthermore, it can be realized that the floating ball is timed to rise to a certain height similar to dripping, so that the pressing lever rotates in the reverse direction to an opposite inclination angle.

5. The water control automatic interactive three-way irrigation valve according to any one of claims 2-4, characterized in that: First magnet blocks are arranged at both ends of the pressing lever. Second magnet blocks are arranged at the bottoms of the two water-full self-stop valves. The two first magnet blocks and the two second magnet blocks correspond to each other up and down one by one and can be adsorbed and matched.

6. An automated irrigation system without electricity, characterized in that: It includes a plurality of three-way valves connected in sequence. The three-way valve adopts the water-controlled automatic interactive three-way irrigation valve according to any one of claims 1-5.
