DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figures 1 to 10 The present invention provides a technical solution: a high-density liquid pipeline fast regulating valve, comprising:

[0040] A valve body 1, to which a water inlet pipe 2 and a water outlet pipe are connected respectively, and the water inlet pipe 2 is connected to the main water injection pipe, and the valve body 1 can control the opening of the water outlet pipe;

[0041] The water outlet is installed at the water outlet pipe, and the water outlet has three irrigation states:

[0042] State 1: The outlet of the water outlet is inserted below the soil surface and can directly inject water into the ground;

[0043] State 2: The water outlet of the water outlet is switched to the periphery of the crop, and can spray the crop in a circular manner;

[0044] State 3: The water outlet of the water outlet is switched to the position close to the root of the crop and close to the soil, and can drip irrigation to the soil surface;

[0045] The external monitoring component is used to monitor the growth stage of the crop and control the water outlet to switch between three irrigation states according to the growth stage of the crop.

[0046] When the quick regulating valve is put into use, it is installed at the branch end of the main water injection pipeline and placed close to the crops. The growth cycle of the crops is monitored through external monitoring components, and the water pressure in the water inlet pipe of the regulating valve is adjusted according to different growth cycles. Specifically:

[0047] In the early seedling stage, the valve body 1 adjusts the water pressure to a medium pressure by controlling the opening of the water outlet pipe, and at the same time, the water outlet installed at the water outlet pipe of the valve body 1 is adjusted to state 1 (i.e., underground direct irrigation mode) to directly transport water to the vicinity of the root system, which helps the root system to expand and penetrate into the soil, and also reduces the evaporation waste of water on the soil surface. Moreover, if nutrient solution or other nutrients are added to the irrigation liquid, it can also help the direct absorption of the root system;

[0048] In the mid-term rapid growth stage, the valve body 1 adjusts the water pressure to a high pressure by controlling the opening of the water outlet pipe, and at the same time, the water outlet installed at the water outlet pipe of the valve body 1 is adjusted to state three (i.e., spray mode), thereby providing a wider range of water coverage, and water can also be sprayed on leaves and stems to assist the rapid growth of crops. Spraying can not only reduce the temperature of the crop leaf surface, reduce the transpiration caused by high temperature, and help crops retain moisture in hot weather, but also help clean the crop leaf surface, remove dust and other particulate matter, and improve the efficiency of photosynthesis. In addition, when fertilizing or applying pesticides, nutrients and pesticides are directly sprayed onto the leaf surface in the form of an aqueous solution, which can improve the utilization efficiency of fertilizers and pesticides.

[0049] In the subsequent maturity period and flowering and fruiting period, the valve body 1 adjusts the water pressure to a low pressure by controlling the opening of the water outlet pipe. At the same time, the water outlet installed at the water outlet pipe of the valve body 1 is adjusted to state 2 (i.e., drip irrigation mode), which helps maintain the quality of the fruit by providing a stable and appropriate amount of water, and avoids excessive or insufficient water affecting the yield and quality;

[0050] In this way, by controlling the watering method, it can be switched according to the growth stage of the crop, providing the most suitable water and nutrient supply at different growth stages of the crop, which can not only reduce the waste of water resources, but also improve the growth efficiency, yield and quality of the crop. It is suitable for use in sandy soil environments or relatively arid environments.

[0051] In one of the more preferred embodiments, it also includes a pressure regulating unit for controlling the water flow pressure in the water inlet pipe 2 and a pressure sensor arranged inside the valve body 1. The pressure regulating unit synchronously controls the water flow pressure in the water inlet pipe according to the switching of the irrigation state of the water outlet.

[0052] When adjusting the water pressure in the pipe, the water flow pressure in the water inlet pipe can be controlled by the pressure regulating part and the pressure sensor in the valve body 1, and the pressure regulating part can directly adjust the water flow at the main water injection pipe, so as to control the water flow pressure of these branch pipes to match the required water flow pressure under the above-mentioned different conditions.

[0053] In one of the more preferred embodiments, it also includes an opening adjustment part arranged in the valve body 1, which synchronously controls the opening of the valve body 1 according to the switching of the irrigation state of the water outlet part to control the water output at the water outlet pipe.

[0054] The opening adjustment part can be electrically controlled or mechanically controlled, specifically, it can be a ball valve, that is, the flow rate is controlled by rotating the internal ball, or it can be a butterfly valve, that is, the flow rate is controlled by rotating the internal disc, and both are suitable for processing high-density mixed liquids, that is, the liquid density is increased due to the addition of nutrient solution or other substances to the irrigation water;

[0055] In this way, the water outflow at the water outlet pipe (ie, the water outlet) is controlled by controlling the opening of the valve body 1, thereby coordinating the water volume and water pressure required after switching between the above-mentioned different states.

[0056] In one of the more preferred embodiments, the external monitoring component uses remote sensing technology and image processing technology.

[0057] Through remote sensing technology and image processing, the color, shape and other appearance characteristics of crops can be analyzed to determine their growth stage. These technologies include drones, satellite images and sensors, which can monitor the health and growth of crops in real time so that switching between watering states can be controlled in real time.

[0058] In one of the more preferred embodiments, an implementation of the above-mentioned water outlet is provided;

[0059] The water outlet part includes a shunt pipe 3 connected to the water outlet pipe of the valve body 1, the inner wall of the shunt pipe 3 is installed with a rotating core 5 that can be rotated and adjusted, and both ends of the rotating core 5 are fixed with right-angle through pipes 6 that pass through the front and rear sides of the shunt pipe 3, and the right-angle through pipes 6 are connected with the inside of the shunt pipe 3, and the water outlet ends of the two right-angle through pipes 6 are installed with a liquid spray part, and the outer wall of the middle of the shunt pipe 3 is connected with a buried pipe 11 for burying underground;

[0060] The water outlet part further includes a switching part arranged in the rotating core 5, and the switching part is used to connect the buried pipe 11 or the right-angle through pipe 6 with the water outlet pipe.

[0061] For details, please refer to Figure 1 and Figure 5 When the regulating valve is in use, the buried pipe 11 is first buried in a position close to the roots of the crop seedlings. A fork can also be set at the end of the buried pipe 11 to increase the tributaries buried underground. After installation, during the watering process, the rotating core 5 is driven to rotate by the external driving structure, and the buried pipe 11 or the right-angle through pipe 6 is connected to the water outlet pipe through the switching part, so that the underground irrigation mode and the water spraying mode of the spraying part can be switched to achieve the purpose of the above-mentioned state one.

[0062] In one of the more preferred embodiments, an implementation of the above-mentioned switching unit is provided;

[0063] The switching part includes a connecting channel 21 provided in the rotating core 5, and the connecting channel 21 is provided along the diameter direction of the rotating core 5. A switching tube 22 is slidably installed on the inner wall of the connecting channel 21. A tension spring 24 is connected between the switching tube 22 and the inner wall of the connecting channel 21 away from the water outlet pipe. A connecting gap 25 is also provided inside the rotating core 5, and the connecting gap 25 can connect the connecting channel 21 with the buried pipe 11. A connecting hole 23 is provided on the outer wall of the switching tube 22, and the connecting hole 23 can communicate with the right-angle through pipe 6 or the connecting gap 25.

[0064] The switching part also includes a traction rope 26 connected between the inner wall of the water outlet pipe and the inner wall of the connecting channel 21 .

[0065] For details on the switching part, please refer to Figure 5 Due to the effect of the traction rope 26, when the rotating core 5 rotates to the horizontal state of the connecting channel 21, the traction rope 26 is in a straightened state, and the tension spring 24 is in a contracted state. At this time, the communication gap 25 is in a connected state with the buried pipe 11, and the switching pipe 22 is also in a position close to the buried pipe 11. The communication gap 25 is connected with the buried pipe 11 through the connecting hole 23 thereon. Similarly, the wall of the switching pipe 22 will close the right-angle through pipe 6, so as to achieve the purpose of switching to state one;

[0066] When it is necessary to switch to other states, the connecting gap 25 is disconnected from the buried pipe 11 by rotating the rotating core 5. In this process, the traction rope 26 will change from a straight state to a bent state as the rotating core 5 rotates, and no matter which direction the rotating core 5 rotates, the change in the state of the traction rope 26 will pull the switching tube 22 to move away from the buried pipe 11, and at the same time, the tension spring 24 is stretched. As the switching tube 22 moves, the connecting hole 23 thereon will be disengaged from the connecting gap 25 and connected to the right-angle through pipe 6, thereby completing the process of switching from state 1 to other states.

[0067] It is worth noting that during the rotation of the rotating core 5, the connecting channel 21 will always remain connected with the water outlet pipe, thereby ensuring the normal flow of water.

[0068] In one of the more preferred embodiments, an implementation of the above-mentioned liquid spraying part is provided;

[0069] The liquid spraying part includes an outer arc tube 7 rotatably mounted at the water outlet position of the right-angle through pipe 6, an inner arc tube 9 is slidably mounted on the inner wall of the outer arc tube 7, and a spring 17 is connected between the inner arc tube 9 and the convex ring on the inner wall of the outer arc tube 7, and the outer arc tube 7 and the inner arc tube 9 are both provided with water spraying ports 8 on the arc surface outer walls, and the end of the inner arc tube 9 extending outward is also connected to a drip irrigation head 10, and a pressure valve is also installed on the inner wall of the end of the inner arc tube 9;

[0070] The liquid spraying part also includes two gears 13 meshing with each other, one of which is coaxially fixed on the outer wall of the right-angle through-tube 6, and the other gear 13 is rotatably installed on the outer wall of the shunt tube 3, and is coaxially fixed with a winding wheel 14, on which a pull rope 12 is fixed and wound, and the extended end of the pull rope 12 passes around the clamping ring on the outer wall of the outer arc tube 7 and is fixed on the outer wall of the end of the inner arc tube 9. When the right-angle through-tube 6 swings downward, the winding wheel 14 will reel in the pull rope 12.

[0071] As can be seen from the above, when the rotating core 5 and the right-angle through-tube 6 rotate upward or downward, the traction rope 26 will pull the switching tube 22 to move after bending, so that the connecting hole 23 on it is connected with the right-angle through-tube 6, thereby completing the water outlet switching mode;

[0072] Specifically, when the rotating core 5 is Figure 5 When the instantaneous hand rotates, the traction rope 26 pulls the switching tube 22 to move and connect the connecting hole 23 with the right-angle through tube 6. At the same time, the right-angle through tube 6 will rotate with the rotating core 5, and in the process of rotation, under the action of the meshing of the two gears 13, the winding wheel 14 will rotate in the opposite direction of the rotating core 5 to reel the pull rope 12, and the reeling of the pull rope 12 will drive the built-in arc tube 9 to slide into the outer arc tube 7 until it rotates to Fig. 9It is worth noting that when the built-in arc tube 9 is retracted into the outer arc tube 7, the water spray ports 8 opened on the outer walls of the two will be staggered and closed, and the drip irrigation head 10 will also be closer to the soil surface near the crop. At this time, when there is water in the water outlet pipe, the water will flow through the right-angle through pipe 6 to the built-in arc tube 9 and the outer arc tube 7, and flow out through the drip irrigation head 10, so that the drip irrigation mode is switched to the second state.

[0073] On the contrary, when the rotating core 5 is Figure 5 When the state rotates counterclockwise, the right-angle through-tube 6 will rotate upward accordingly. When the switching tube 22 connects the connecting hole 23 with the right-angle through-tube 6, the winding wheel 14 unwinds under the transmission of the two gears 13 meshing with each other, and the pull rope 12 is released. The built-in arc tube 9 will extend outward under the elastic force of the spring 17 until it is completely extended from the outer arc tube 7. At this point, the water spraying ports 8 opened on the two are fully connected and are also in a higher spraying position, such as Figure 8 As shown, at this time, when there is water in the water outlet pipe, the water will flow through the right-angle through pipe 6 to the inner arc pipe 9 and the outer arc pipe 7, and spray from the water spray port 8 to the leaves or stems of the crop, switching to the spray mode, that is, state three. In this process, due to the setting of the pressure valve and the adjustment of the water pressure in the pipe, the water will only be sprayed from the water spray port 8, and will no longer flow out from the drip irrigation head 10;

[0074] In summary, when the rotating core 5, i.e., the right-angle through tube 6, rotates from top to bottom, when the right-angle through tube 6 faces upward, Figure 8 As shown, this corresponds to the spray mode of state three. When the right-angle through pipe 6 rotates to the horizontal position, as shown in FIG. Figure 6 As shown, this corresponds to the underground direct irrigation mode of state 1. When the right-angle through pipe 6 rotates to face the bottom, as shown in FIG. Fig. 9 As shown, this corresponds to the drip irrigation mode of state 2;

[0075] In this way, the switching between the irrigation states can be completed by adjusting the rotation position of the right-angle through pipe 6, so as to achieve the purpose of coordinating with different growth stages of crops.

[0076] In one of the more preferred embodiments, an implementation method of controlling the opening of the valve body 1 is provided;

[0077] The top of the valve body 1 is provided with a valve stem, and a worm gear 18 for controlling the closing degree of the valve body 1 is installed on the valve stem. A mounting portion 4 is also installed on the top of the valve body 1, and a worm 19 meshing with the worm gear 18 is rotatably installed in the mounting portion 4. A servo motor for driving the worm 19 to rotate is also installed on the outer wall of the mounting portion 4. The two ends of the worm 19 are respectively connected to the axial sections of the two right-angle through pipes 6 through a synchronous belt assembly 20.

[0078] See also Figure 4 Regardless of whether the valve body 1 adopts the above-mentioned ball valve or butterfly valve adjustment method, the rotation angle of the valve stem is used to control the size of its opening. Therefore, in this case, the opening size of the valve body 1 is adjusted by driving the worm 18 to rotate through the worm 19, and the worm 19 will also drive the right-angle through pipe 6 to rotate together through the synchronous belt assembly 20 during the rotation process, so that the adjustment of its opening size and the switching of the irrigation mode are synchronized;

[0079] First of all, the size of the opening is related to the water pressure in the outlet pipe. From the above content, we can know that:

[0080] In the state three spray mode, the required water pressure is high water pressure to ensure the spraying of the spray water, so the spray mode corresponds to the initial state of rotation of the worm 19, that is, the state of the maximum opening of the valve body 1;

[0081] In the state 1 underground direct irrigation mode, the required water pressure is medium water pressure to ensure that water can penetrate into the soil, so the spray mode corresponds to the middle state of the rotation of the worm 19, that is, the state of the valve body 1 at a medium opening;

[0082] In the drip irrigation mode of state 2, the required water pressure is a small water pressure to ensure the stable dripping of water flow, so the drip irrigation mode corresponds to the final state of the rotation of the worm 19, that is, the state of the small opening of the valve body 1;

[0083] In summary, while the worm 19 drives the worm wheel 18 to rotate to adjust the opening of the valve body 1, it will also synchronously control the switching of its irrigation mode and adapt the water pressure to different irrigation modes to ensure that different modes correspond to different water pressures, further ensuring the irrigation effect.

[0084] In one of the more preferred embodiments, an incomplete bevel gear 15 is also fixed to the outer wall of the outer arc tube 7, and an arc-shaped rack 16 is fixed to the side wall of the shunt tube 3 near the upper position. When the right-angle through tube 6 swings upward, the incomplete bevel gear 15 will contact and engage with the arc-shaped rack 16. The outer wall of the incomplete bevel gear 15 is also provided with a long groove for the pull rope 12 to pass through and move.

[0085] In order to further improve the spraying range and spraying effect of crops in the spraying mode, refer to Figure 1 and Figure 8 When the right-angle through-tube 6 swings upward, the incomplete bevel gear 15 will be in contact and mesh with the arc-shaped rack 16, so that the outer arc tube 7 will rotate toward the middle, forming a central spraying form, further improving the spraying effect, and also making the water more concentrated and reducing water waste.

[0086] In one of the more preferred embodiments, the outer wall of the outer sleeve arc tube 7 is also provided with hooks or protruding nails that can be used to hang the shielding cloth.

[0087] See also Figure 2 , Figure 2 This is the underground direct irrigation mode of state one, at which the outer arc tube 7 and the inner arc tube 9 are in an extended and horizontal state. From the above content, it can be seen that state one corresponds to the crop seedling stage. Therefore, in some areas with sandy soil, a shielding cloth can be added between the hook on the outer arc tube 7 and the ground to reduce the impact of wind and sand on the crop seedling stage, so as to ensure the normal growth of the crop.

[0088] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0089] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
