Description

Technical Field

[0001] This utility model relates to the field of irrigation technology, specifically to a water-controlled automatic interactive three-way irrigation valve and an electric-free automatic irrigation system. Background Technology

[0002] In urban greening, desertification control, soilless cultivation, and agricultural production, the application of irrigation technologies such as sprinkler and drip irrigation is indispensable.

[0003] However, most irrigation is currently controlled manually. Even in places where conditions permit, automated irrigation must be used in an environment with electricity. This is because most existing automated irrigation systems are designed based on intelligent control electric irrigation valves, which require long-term power supply, have a short service life, and involve the processing of control signals, making the system relatively complex, costly, and difficult to maintain.

[0004] Furthermore, electricity is very inconvenient in remote fields and other locations used for urban greening, desertification control, and agricultural production.

[0005] Therefore, there is an urgent need to design a water valve and system that can achieve automatic irrigation without electricity in an environment where no one is on duty for a long time. Summary of the Invention

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by providing a water-controlled automatic interactive three-way irrigation valve and an electricity-free automatic irrigation system.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: a water-controlled automatic interactive three-way irrigation valve, comprising a three-way valve consisting of an inlet main pipe and two outlet water pipes, wherein each of the two outlet water pipes is equipped with a water-full automatic shut-off valve;

[0008] The bottom pressure relief hole of the automatic shut-off valve when the water is full is connected to the water outlet through a flexible conduit with a rubber cap, and the rubber cap covers the bottom pressure relief hole of the automatic shut-off valve when the water is full.

[0009] A sealing mechanism is provided below the two water-full automatic stop valves. The sealing mechanism can alternately squeeze the two rubber caps to alternately block the bottom pressure relief holes of the two water-full automatic stop valves, thereby allowing the two water-full automatic stop valves to open and close alternately.

[0010] Based on the above, the sealing mechanism includes a pressure lever and a drive assembly. The pressure lever is positioned below the two water-full automatic shut-off valves and its vertical projection coincides with the line connecting the bottom pressure relief holes of the two water-full automatic shut-off valves. The central fulcrum of the pressure lever is located in the middle of the bottom pressure relief holes of the two water-full automatic shut-off valves. Two pressure plugs are symmetrically arranged on the pressure lever about the central fulcrum, and the two pressure plugs correspond one-to-one with the two rubber caps. The drive assembly can drive the pressure lever to rotate back and forth around the central fulcrum, so that the two pressure plugs alternately squeeze the two rubber caps, thereby deforming the two rubber caps under pressure and alternately blocking the bottom pressure relief holes of the two water-full automatic shut-off valves, causing the two water-full automatic shut-off valves to open and close alternately.

[0011] The pressure lever is initially tilted so that one of the pressure plugs squeezes the corresponding rubber cap, thereby closing the corresponding water-full automatic stop valve, while the other pressure plug does not contact the corresponding other rubber cap, thus opening the corresponding other water-full automatic stop valve.

[0012] Based on the above, the drive assembly includes a support frame, a weighted water box, and a counterweight. Two water outlet pipes are installed on the support frame. The upper end of the weighted water box is open. The weighted water box is rotatably mounted on the support frame via a bracket and is located directly below the pressure lever. The pivot point connecting the weighted water box to the bracket is located at the eccentric position of the weighted water box. The counterweight is positioned on the side of the weighted water box closer to the pivot point, allowing the weighted water box to remain horizontal within a certain water volume range. A connecting rod connects the weighted water box to the pressure lever; when the weighted water box is flipped, the connecting rod drives the pressure lever to rotate. Initially opened... A first outlet valve with an adjustable opening to control the dripping speed is installed at the outlet of the automatic shut-off valve when the water is full. The first outlet valve can drip water into the eccentric water box. A second outlet valve with an adjustable opening to control the dripping speed is provided on the lower part of the side of the eccentric water box that is farther away from the rotation fulcrum. The second outlet valve can make water drip out of the eccentric water box. The dripping speed of the first outlet valve is greater than that of the second outlet valve. By adjusting the opening of the first outlet valve and the second outlet valve, the rate at which the water volume in the eccentric water box increases can be controlled. In this way, the eccentric water box can be controlled to flip from a horizontal state due to the increase in water volume, similar to dripping, so that the pressure lever rotates in the opposite direction to tilt at the opposite angle.

[0013] Based on the above, the drive assembly includes a support box and a float. The upper end of the support box is open. The support box is installed below the two water outlet pipes and corresponds vertically to the two water-filled automatic shut-off valves. The two water-filled automatic shut-off valves are located in the upper port of the support box. The support box contains water, and the water level is lower than the pressure lever. The float floats on the water surface in the support box and is connected to the pressure lever via a traction rod. When the float moves up and down with the water level, it can drive the pressure lever to rotate through the traction rod. A movable valve is installed at the outlet of the initially opened water-filled automatic shut-off valve. A first water outlet valve with adjustable opening to control the dripping speed is provided, which can drip water into the support tank. A second water outlet valve with adjustable opening to control the dripping speed is provided on the lower side of the support tank, which can make water drip out of the support tank. The dripping speed of the first water outlet valve is greater than that of the second water outlet valve. By adjusting the opening of the first and second water outlet valves, the rising speed of the water level in the eccentric water box can be controlled, thereby achieving timed control of the float to rise to a certain height, similar to dripping, so that the pressure lever rotates in the opposite direction to tilt at the opposite angle.

[0014] Based on the above, a first magnet is provided at both ends of the pressure lever, and a second magnet is provided at the bottom of the two water-full automatic shut-off valves. The two first magnets correspond one-to-one with the two second magnets and can be attracted and engaged.

[0015] An electric-free automated irrigation system includes a plurality of three-way valves connected in sequence, wherein the three-way valves are water-controlled automatic interactive three-way irrigation valves as described above.

[0016] This invention represents a substantial improvement over existing technologies. Specifically, it involves installing the automatic shut-off valves on the two water outlet pipes forming a three-way valve. A pressure lever is used to alternately press two pressure plugs against the rubber caps at the bottom pressure relief holes of the corresponding two automatic shut-off valves, thus blocking the pressure relief holes and allowing the two valves to open and close alternately. The pressure lever is driven by a weighted water box or float, utilizing gravity or buoyancy, and is controlled by water. This completely eliminates the dependence on electricity in traditional intelligent electric irrigation valves, enabling automated control. It can be used outdoors in environments without electricity, suitable for unattended environments, saving time and labor. Compared to existing intelligent electric irrigation valves, this water-controlled automatic interactive three-way irrigation valve has a simple structure, stable performance, low cost, and is easy to use. It eliminates the need to consider electricity consumption, has no electronic components dependent on electricity, has a long lifespan, and is easy to maintain.

[0017] Furthermore, an electric-free automated irrigation system is provided, which uses a water-controlled automatic interactive three-way irrigation valve. This irrigation system, which is not constrained by power supply, can achieve automatic irrigation in an unattended environment all year round. It is low-cost, time-saving, labor-saving and worry-free, and can be widely used in urban greening, desert transformation and agricultural planting. Attached Figure Description

[0023] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0024] Example 1

[0025] like Figure 1 and Figure 2 As shown, the water-controlled automatic interactive three-way irrigation valve includes a three-way valve consisting of an inlet main pipe 1 and two outlet water pipes 2. Each of the two outlet water pipes 2 is equipped with a water-full automatic shut-off valve 3.

[0026] The bottom pressure relief hole of the water-full automatic stop valve 3 is connected to 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 automatic stop valve 3.

[0027] A sealing mechanism 5 is provided below the two water-full automatic stop valves 3. The sealing mechanism 5 can alternately squeeze the two rubber caps 4 to alternately block the bottom pressure relief holes of the two water-full automatic stop valves 3, thereby allowing the two water-full automatic stop valves 3 to open and close alternately.

[0028] The sealing mechanism 5 includes a pressure lever 6 and a drive assembly. The pressure lever 6 is located below the two water-full self-stop valves 3 and its vertical projection coincides with the line connecting the bottom pressure relief holes of the two water-full self-stop valves 3. The central fulcrum of the pressure lever 6 is located 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 about the central fulcrum. The two pressure plugs 7 correspond one-to-one with the two rubber caps 4. The drive assembly can drive the pressure lever 6 to rotate back and forth around the central fulcrum, so that the two pressure plugs 7 respectively and alternately squeeze the two rubber caps 4, thereby causing the two rubber caps 4 to be deformed by pressure and alternately block the bottom pressure relief holes of the two water-full self-stop valves 3, so that the two water-full self-stop valves 3 alternately open and close.

[0029] When the pressure lever 6 is initially tilted, one of the pressure plugs 7 can squeeze the corresponding rubber cap 4, thereby closing the corresponding water-full self-stop valve 3, while the other pressure plug 7 does not contact the corresponding other rubber cap 4, thus opening the corresponding other water-full self-stop valve 3.

[0030] The drive assembly includes a support frame 8, a eccentric water tank 9, and a counterweight 10. Two water outlet pipes 2 are mounted on the support frame 8. The eccentric water tank 9 has an open top and is rotatably mounted on the support frame 8 via a bracket 11, located directly below the pressure lever 6. The pivot point connecting the eccentric water tank 9 and the bracket 11 is located at the eccentric position of the eccentric water tank 9. The counterweight 10 is positioned on the side of the eccentric water tank 9 closer to the pivot point, allowing the eccentric water tank 9 to remain horizontal within a certain water volume range. A connecting rod 22 connects the eccentric water tank 9 and the pressure lever 6. When the eccentric water tank 9 is flipped, the connecting rod 22 drives the pressure lever 6 to rotate. Initially opened... A first outlet valve 12 with adjustable opening to control the dripping speed is installed at the outlet of the automatic shut-off valve 3 when the water is full. The first outlet valve 12 can drip water into the eccentric water box 9. A second outlet valve 13 with adjustable opening to control the dripping speed is provided on the lower part of the side of the eccentric water box 9 that is farther away from the rotation fulcrum. The second outlet valve 13 can make water drip out of the eccentric water box 9. The dripping speed of the first outlet valve 12 is greater than that of the second outlet valve 13. By adjusting the opening of the first outlet valve 12 and the second outlet valve 13, the rate at which the water volume in the eccentric water box 9 increases can be controlled. In this way, the eccentric water box 9 can be controlled to flip from a horizontal state due to the increase in water volume, similar to dripping, so that the pressure lever 6 rotates in the opposite direction to tilt at the opposite angle.

[0031] In this embodiment, gravity is used to drive the pressure lever 6 to rotate, thereby causing the two water-full self-stop valves 3 to open and close alternately.

[0032] The specific operating principle is as follows: Water enters the main inlet pipe, and the outlet pipe 2, where the initially opened automatic shut-off valve 3 is located, is opened to release water. The outlet pipe 2, where the initially closed automatic shut-off valve 3 is located, is closed to stop the water flow. The eccentric water box 9 remains horizontal under the action of the counterweight 10. The first outlet valve 12 on the initially opened automatic shut-off valve 3 drips water into the eccentric water box 9. At the same time, the second outlet valve 13 drips water out of the eccentric water box 9. By adjusting the opening of the first outlet valve 12 and the second outlet valve 13, the water volume in the eccentric water box 9 gradually increases. When the eccentric... When the water level in water box 9 reaches or exceeds a certain value, the eccentric water box 9 rotates and tilts around the pivot point under the influence of gravity. The side of the eccentric water box 9 farther from the pivot point flips downwards. Then, the eccentric water box 9, through the connecting rod 22, drives the pressure lever 6 to rotate in the opposite direction and tilt to the opposite angle. This causes the initially pressed plugs 7 and rubber caps 4 to separate, opening the initially blocked bottom pressure relief hole of the water-full automatic stop valve 3. This opens the initially closed water-full automatic stop valve 3, conversely, the initially separated and non-contacting... When the pressure plugs 7 and rubber caps 4 begin to press against each other, the pressure relief hole at the bottom of the initially unblocked water-filled automatic shut-off valve 3 is blocked, and the initially open water-filled automatic shut-off valve 3 turns to the closed state. The first outlet valve 12 stops dripping, while the second outlet valve 13 continues to drip. When the water level in the eccentric water box 9 decreases to a certain range, the eccentric water box 9 will flip back to a horizontal state under the action of the counterweight 10, causing the pressure lever 6 to rotate forward back to its initial tilted state. Then, the two pressure plugs 7 return to their initial state. Similarly, the two... The water-full automatic shut-off valve 3 is also converted to its initial state. In this way, the two water-full automatic shut-off valves 3 can be opened and closed alternately, and the two water outlet pipes 2 can be opened and closed alternately. The process of the two water-full automatic shut-off valves 3 being opened and closed alternately is entirely controlled by water, which can realize automatic control. It can be used in outdoor environments without electricity and is suitable for unattended environments. It is worry-free and labor-saving. Compared with the existing intelligent control electric irrigation valves, the water-controlled automatic interactive three-way irrigation valve of this utility model has a simple structure, stable performance, low cost, and convenient use. There is no need to consider the power supply problem. There are no electronic components that rely on electricity. It has a long service life and simple maintenance.

[0033] The water-controlled automatic interactive three-way irrigation valve of this utility model can be set with multiple interactive cycles (from tens of seconds to hundreds of hours, controlled by the opening of the first outlet valve 12 and the second outlet valve 13).

[0034] Example 2

[0035] Unlike Example 1, as Figure 3 As shown, the drive assembly includes a support box 14 and a float 15. The upper end of the support box 14 is open. The support box 14 is installed below the two water outlet pipes 2 and corresponds vertically to the two water-filled automatic shut-off valves 3. The two water-filled automatic shut-off valves 3 are placed in the upper port of the support box 14. The support box 14 contains water, and the water level is lower than the pressure lever 6. The float 15 floats on the water surface inside the support box 14 and is connected to the pressure lever 6 through a traction rod 16. When the float 15 moves up and down with the water level, it can drive the pressure lever 6 to rotate through the traction rod 16. An automatic shut-off valve 3 is installed at its outlet when it is initially opened. A first water outlet valve 12 with adjustable opening to control the dripping speed is provided. The first water outlet valve 12 can drip water into the support tank 14. A second water outlet valve 13 with adjustable opening to control the dripping speed is provided on the lower side of the support tank 14. The second water outlet valve 13 can make water drip out of the support tank 14. 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 of the first water outlet valve 12 and the second water outlet valve 13, the rising speed of the water level in the eccentric water box 9 can be controlled. In this way, the float 15 can be controlled to rise to a certain height at a time, similar to dripping, so that the pressure lever 6 can be rotated in the opposite direction to tilt at the opposite angle.

[0036] In this embodiment, buoyancy is used to drive the pressure lever 6 to rotate, thereby causing the two water-filled self-stop valves 3 to open and close alternately.

[0037] The specific operating principle is as follows: Water enters the main inlet pipe, and the outlet pipe 2, where the initially opened automatic shut-off valve 3 is located, is opened to release water. The outlet pipe 2, where the initially closed automatic shut-off valve 3 is located, is disconnected to stop the water flow. The float 15 is at a low water level in the support tank 14. The first outlet valve 12 on the initially opened automatic shut-off valve 3 drips water into the support tank 14. At the same time, the second outlet valve 13 drips water out of the support tank 14. The opening of the first outlet valve 12 and the second outlet valve 13 is adjusted to gradually raise the water level in the support tank 14. When the water level in the support tank 14 reaches or exceeds a certain height, the float 15 rises under the buoyancy of the water. Then, the float 15 drives the pressure lever 6 to rotate in the opposite direction to tilt at the opposite angle through the traction rod 16, causing the initially pressed plug 7 and the rubber cap 4 to separate, opening the initially blocked... The pressure relief hole at the bottom of the self-closing valve 3 when full is opened will cause the initially closed self-closing valve 3 to open. Conversely, the initially separated and non-contacting set of pressure-applying plugs 7 and rubber caps 4 will begin to press and contact each other, blocking the initially unblocked pressure relief hole at the bottom of the self-closing valve 3. The initially open self-closing valve 3 will then close, causing the first outlet valve 12 to stop dripping, while the second outlet valve 13 will continue dripping. When the water level in the support tank 14 drops to its initial position, the float 15 will drop back to the low water level, causing the pressure lever 6 to rotate forward to its initial tilted state. The two pressure-applying plugs 7 will then return to their initial state. Similarly, the two self-closing valves 3 will also return to their initial state. In this way, the two self-closing valves 3 can be opened and closed alternately, and the two outlet water pipes 2 can be switched on and off alternately. The technical effect is the same as in Embodiment 1, and will not be repeated here.

[0038] It should be noted that in other embodiments, in addition to using gravity and buoyancy to drive the pressure lever 6 to rotate, the driving component can also drive the pressure lever 6 to rotate through various forces that can generate action, such as water pressure in the pipe and electromagnetic induction. That is, all methods that can drive the pressure lever 6 to rotate can be applied to achieve the same effect as in embodiments 1 and 2.

[0039] Example 3

[0040] like Figure 2 and Figure 3As shown, based on Embodiment 1 or Embodiment 2, in order to improve the reliability of the rotation of the pressure lever 6 and ensure that the pressure plug 7 squeezes the corresponding rubber cap 4 more tightly, a first magnet block 17 is provided at both ends of the pressure lever 6, and a second magnet block 18 is provided at the bottom of each of the two water-full self-stop valves 3. The two first magnet blocks 17 correspond one-to-one with the two second magnet blocks 18 and can be attracted to each other. When the pressure lever 6 rotates, when one end of the pressure lever 6 gradually approaches the corresponding water-full self-stop valve 3, the first magnet block 17 at this end will attract the corresponding second magnet block 18 above it, thereby making the pressure lever 6 rotate into position quickly and more reliably.

[0041] Example 4

[0042] Using the above technologies, such as Figure 4 As shown, this embodiment also provides an electric-free automated irrigation system, which includes a plurality of three-way valves connected in sequence, wherein the three-way valves are water-controlled automatic interactive three-way irrigation valves as described above.

[0043] In practical use, each of the aforementioned water-controlled automatic interactive three-way irrigation valves is arranged in the area requiring irrigation according to the irrigation sequence. The main inlet pipe 1 of the first water-controlled automatic interactive three-way irrigation valve is connected to the water supply pipe 19 for irrigation. An irrigation device 20 is installed on the initially open outlet pipe 2 of each water-controlled automatic interactive three-way irrigation valve. The initially closed outlet pipe 2 is connected to the main inlet pipe 1 of the next water-controlled automatic interactive three-way irrigation valve through a water conveyance pipe 21. The initially closed outlet pipe 2 of the last water-controlled automatic interactive three-way irrigation valve is directly blocked or connected to the downstream pipe.

[0044] In practical use, water is supplied to the main inlet pipe 1 of the first water-controlled automatic interactive three-way irrigation valve, and water is released from the initially open outlet pipe 2 of the first water-controlled automatic interactive three-way irrigation valve. The irrigation device 20 then irrigates. Referring to the operating principle in Embodiment 1 or Embodiment 2, after a certain period of time, the initially open outlet pipe 2 of the first water-controlled automatic interactive three-way irrigation valve is switched off, and the irrigation device 20 stops irrigating. The initially closed outlet pipe 2 of the first water-controlled automatic interactive three-way irrigation valve is then switched on, and water begins to be released and supplied to the second water-controlled automatic interactive three-way irrigation valve via the water supply pipe 21. The irrigation device 20 installed on the second water-controlled automatic interactive three-way irrigation valve then begins irrigating. In this way, irrigation of each area requiring irrigation can be completed sequentially, ensuring that the water pressure and output of each irrigation device are basically the same, while reducing water waste. Each such irrigation system can be equipped with different numbers of the aforementioned water-controlled automatic interactive three-way irrigation valves according to actual needs. Such irrigation systems, which are not constrained by power supply, can achieve automatic irrigation in unattended environments all year round. They are low-cost, time-saving, labor-saving, and worry-free, and can be widely used in urban greening, desert transformation, and agricultural planting.

[0045] Furthermore, in this non-electric automated irrigation system, the water-controlled automatic interactive three-way irrigation valve controls the water release time of each irrigation device 20 to be basically synchronized with the soil moisture. The opening degree of the first water outlet valve 12 and the second water outlet valve 13 can also be manually adjusted according to the water requirements of the crop to adjust the time (cycle) of the two water outlet pipes 2 to switch on and off, thereby adjusting the water release and water stop time of the irrigation device 20. Soil moisture is related to the weather. When it rains, rainwater enters the eccentric water box 9 in Example 1 or the supporting box 14 in Example 2, causing the water volume in the eccentric water box 9 or the supporting box 14 to increase much faster than usual. This causes the eccentric water box 9 to flip earlier or the float 15 to rise to a certain height earlier, thereby causing the pressure lever 6 to rotate to the opposite angle earlier and close the water-filled automatic shut-off valve 3 on the water outlet pipe 2 of the irrigation device 20 earlier, thus reducing irrigation time or even stopping irrigation. During hot and dry weather, the opposite is true. The water evaporation rate in the eccentric water box 9 or the supporting box 14 will accelerate, causing the water volume in the eccentric water box 9 or the supporting box 14 to increase much slower than usual. This causes the eccentric water box 9 to flip later or the float 15 to rise to a certain height later, thus increasing irrigation time.

[0046] It should be noted that the water level control valve 3 is a float-type water level control valve, which is an existing device and can be purchased on the market. When using it, simply blocking or opening the bottom pressure relief hole of the water level control valve 3 is sufficient to open and close the water level control valve 3.

[0047] In practical applications, the weighted water box 9 and the float ball 15 do not necessarily have to be set below the two water-full automatic shut-off valves 3. The weighted water box 9 and the float ball 15 can be set at any position above, below, left, or right of the two water-full automatic shut-off valves 3.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.

The second outlet valve can make water drip out of the eccentric water box. The dripping speed of the first outlet valve is greater than that of the second outlet valve. By adjusting the opening of the first outlet valve and the second outlet valve, the rate at which the water volume in the eccentric water box increases can be controlled. In this way, the eccentric water box can be controlled to flip from a horizontal state due to the increase in water volume, similar to dripping, so that the pressure lever rotates in the opposite direction to tilt at the opposite angle.

4. The water management automatic interaction tee valve for irrigation according to claim 3, wherein: The drive assembly includes a support box and a float. The upper end of the support box is open. The support box is installed below the two water outlet pipes and corresponds vertically to the two water-filled automatic shut-off valves. The two water-filled automatic shut-off valves are located in the upper port of the support box. The support box contains water, and the water level is lower than the pressure lever. The float floats on the water surface in the support box and is connected to the pressure lever via a traction rod. When the float moves up and down with the water level, it can drive the pressure lever to rotate via the traction rod. An adjustable valve is installed at the outlet of the initially opened water-filled automatic shut-off valve. A first water outlet valve is provided to control the dripping speed, allowing water to drip into the support tank. A second water outlet valve is provided on the lower side of the support tank, allowing water to drip out of the support tank. The dripping speed of the first water outlet valve is greater than that of the second water outlet valve. By adjusting the opening of the first and second water outlet valves, the rising speed of the water level in the eccentric water box can be controlled. This allows the float to rise to a certain height at regular intervals, similar to dripping, causing the pressure lever to rotate in the opposite direction and tilt at the opposite angle.

5. The water management automatic interaction three-way irrigation valve according to any one of claims 2-4, characterized in that: Both ends of the pressure lever are provided with a first magnet block, and the bottom of the two water-full automatic shut-off valves are provided with a second magnet block. The two first magnet blocks correspond one-to-one with the two second magnet blocks and can be attracted and cooperate.

6. An electroless automated irrigation system characterized by: It includes a plurality of three-way valves connected in sequence, wherein the three-way valves are water-controlled automatic interactive three-way irrigation valves as described in any one of claims 1-5.
