A pressure self-balancing drip irrigation pipe for mountainous areas

Abstract

The present invention relates to a pressure self-balancing drip irrigation pipe fitting for mountainous areas. By arranging devices such as a resistance plate, the water flow in the main pipe can rotate the rotating shaft through a paddle when flowing through the flow tube to the inside of the drip irrigation pipe. If the water flow rate is too fast, the rotation speed of the rotating shaft will be faster, and the resistance plate will open under the action of centrifugal force, so that the resistance of the resistance plate will become larger, which can increase the resistance of the paddle and reduce the speed of the water flow. The faster the water flow rate, the larger the opening range of the resistance plate, the greater the resistance, which can effectively reduce the speed of the water flow. Similarly, when the water flow rate is slower, the opening range of the resistance plate is smaller, so as to avoid affecting the normal passage of the water flow. Through the above-mentioned arrangement, the water flow rate at different positions of the main pipe can be better controlled, and the uniformity of fertilization and irrigation is further improved. The size of the water flow is adjusted by the water flow rate, and the drainage volume can be controlled more accurately and directly, so that the water output of multiple drip irrigation holes is more uniform.

Description

Technical Field

[0001] The present invention relates to a pressure self-balancing drip irrigation pipe fitting for mountainous areas, in particular to a pressure self-balancing drip irrigation pipe fitting for mountainous areas applied in the field of drip irrigation. Background Art

[0002] Fruit tree irrigation in mountainous areas utilizes the water potential in the mountains to provide constant water pressure, thereby driving subsequent fertilizer distribution and precision drip irrigation systems. Due to the large difference in mountainous terrain, the water pressure at different locations of the drip irrigation pipes is also different.

[0003] The current solution is to use pressure-compensating drip irrigation pipes. Pressure-compensating drip irrigation pipes are based on the water pressure, and the elastic sheet undergoes corresponding deformation to change the space at the drainage hole to achieve the purpose of changing the drainage volume. The pressure and deformation degree of the elastic sheet are proportional and cannot be changed. It cannot be adjusted according to the actual terrain and the distribution of the drip irrigation pipe, so further improvement is needed.

[0004] Application Contents

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is the problem that the drainage volume of different parts of the drip irrigation pipe is uneven due to the influence of water pressure.

[0006] To solve the above problems, the present invention provides a water source pipe, a fertilizer box and a main pipe, one end of the water source pipe is connected to the input end of the fertilizer box, the output end of the fertilizer box is connected to the main pipe, a plurality of joints are fixedly installed on the side wall of the main pipe, a drip irrigation pipe is provided on one side of the joint, the main pipe is arranged vertically, and a plurality of drip irrigation pipes are arranged horizontally and on the same horizontal plane, a flow tube is fixedly connected between the joint and the drip irrigation pipe, an electromagnetic valve is installed at one end of the drip irrigation pipe close to the flow tube, the inner wall of the flow tube is rotatably connected to a rotating shaft, the outer wall of the rotating shaft is fixedly connected to a plurality of evenly distributed paddles, the top of the flow tube is fixedly connected to an adjusting tube, the top of the rotating shaft extends to the inner side of the adjusting tube, and the top of the rotating shaft is fixedly connected to a column core, the outer wall of the column core is rotatably connected to a plurality of evenly distributed resistance plates, a torsion spring is installed between the column core and the resistance plate, and the interior of the adjusting tube is filled with pure water.

[0007] In the above-mentioned drip irrigation pipe fitting, the size of the water flow is adjusted by the flow velocity of the water flow, so that the drainage volume can be controlled more accurately and directly, so that the water output of multiple drip irrigation holes is more uniform.

[0008] As a further improvement of the present application, the resistance plate is configured to be in an arc shape and surrounds the outer side of the column core.

[0009] As a further improvement of the present application, the side wall of the regulating tube is fixedly connected to an equipment box, the top of the equipment box is fixedly connected to a spare box, and the inner wall of the equipment box is fixedly connected to a liquid pump.

[0010] As a further improvement of the present application, the input end of the liquid pump is connected to the standby tank, the output end of the liquid pump is connected to the regulating pipe, the volume of the standby tank is the same as the volume of the regulating pipe, and the volume of pure water is the same as the volume of the standby tank. Through the above arrangement, the flow rate of the water flow can be further adjusted according to the size of the terrain drop or the spacing between multiple drip irrigation pipes.

[0011] As another improvement of the present application, an electric power box is fixedly connected between the top end of the regulating tube and the side wall of the standby box, and a coupling is fixedly connected to the top end of the column core.

[0012] As another improved supplement of the present application, a micro generator is fixedly connected to the inner wall of the top of the power box, and a battery is fixedly connected to the inner wall of the equipment box.

[0013] As another improved supplement to the present application, the top end of the coupling extends to the inner side of the power box and is fixedly connected to the rotating end of the micro generator. The output end of the micro generator is electrically connected to the battery, and the battery is electrically connected to the liquid pump and the solenoid valve. Through the above arrangement, the power of the column core rotation can be utilized, and the liquid pump can generate electricity to charge the battery, thereby avoiding energy waste and providing power for driving the solenoid valve and the liquid pump.

[0014] As another improvement of the present application, a plurality of evenly distributed spoilers are fixedly connected to the inner wall of the regulating tube; through the above arrangement, the pure water can be disturbed, thereby avoiding the generation of large vortices after the pure water rotates, which would excessively affect the liquid level of the pure water in the regulating tube.

[0015] To sum up, through the arrangement of devices such as the resistance plate, the water flow in the main pipe can rotate the shaft through the paddle when it passes through the flow tube and flows to the inside of the drip irrigation pipe. If the water flow rate is too fast, the faster the rotation speed of the shaft, and the resistance plate opens under the action of centrifugal force, so that the resistance of the resistance plate becomes greater, the resistance of the paddle can be increased, and the speed of the water flow can be reduced. The faster the water flow rate, the greater the opening amplitude of the resistance plate, the greater the resistance, and the water flow rate can be effectively reduced. Similarly, when the water flow rate is slower, the opening amplitude of the resistance plate is smaller, so as to avoid affecting the normal passage of the water flow. Through the above arrangement, the water flow velocity at different positions of the main pipe is better controlled, and the uniformity of fertilization and irrigation is further improved. The size of the water flow is adjusted by the water flow velocity, and the drainage volume can be controlled more accurately and directly, so that the water output of multiple drip irrigation holes is more uniform.

DETAILED DESCRIPTION

[0026] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0027] The first implementation method:

[0028] Figure 1-7The invention shows a pressure self-balancing drip irrigation pipe for mountainous areas, comprising a water source pipe 101, a fertilizer tank 102 and a main pipe 1. One end of the water source pipe 101 is connected to the input end of the fertilizer tank 102, and the output end of the fertilizer tank 102 is connected to the main pipe 1. A plurality of joints 2 are fixedly installed on the side wall of the main pipe 1. A drip irrigation pipe 3 is arranged on one side of the joint 2. The main pipe 1 is arranged vertically, and the plurality of drip irrigation pipes 3 are arranged horizontally and on the same horizontal plane. A flow pipe 4 is fixedly connected between the joint 2 and the drip irrigation pipe 3. The drip irrigation pipe 3 is close to the main pipe 1. A solenoid valve 301 is installed near one end of the flow tube 4. The inner wall of the flow tube 4 is rotatably connected to a rotating shaft 5. The outer wall of the rotating shaft 5 is fixedly connected to a plurality of evenly distributed paddles 6. The top of the flow tube 4 is fixedly connected to an adjusting tube 7. The top of the rotating shaft 5 extends to the inner side of the adjusting tube 7. The top of the rotating shaft 5 is fixedly connected to a column core 8. The outer wall of the column core 8 is rotatably connected to a plurality of evenly distributed resistance plates 9. A torsion spring is installed between the column core 8 and the resistance plates 9. The interior of the adjusting tube 7 is filled with pure water 10. By arranging multiple drip irrigation pipes 3 horizontally on the same plane, the uneven irrigation at different positions of the drip irrigation pipe 3 due to the terrain difference is avoided, and the uniformity of fertilization is improved. At the same time, when the water flow in the main pipe 1 passes through the flow pipe 4 and flows into the interior of the drip irrigation pipe 3, the rotating shaft 5 can be rotated by the paddle 6. If the water flow rate is too fast, the rotation speed of the rotating shaft 5 is faster, and the resistance plate 9 opens under the action of centrifugal force, so that the resistance of the resistance plate 9 becomes larger, the resistance of the paddle 6 can be increased, and the speed of the water flow is reduced. The faster the water flow rate, the larger the opening amplitude of the resistance plate 9 and the greater the resistance, which can effectively reduce the speed of the water flow. Similarly, when the water flow rate is slower, the opening amplitude of the resistance plate 9 is smaller, avoiding affecting the normal passage of the water flow. Through the above arrangement, the water flow rate at different positions of the main pipe 1 is better controlled, and the uniformity of fertilization and irrigation is further improved. The size of the water flow is adjusted by the water flow rate, and the drainage volume can be more accurately and directly controlled, so that the water output of multiple drip irrigation holes is more uniform.

[0029] Multiple resistance plates 9 are arranged in an arc shape and surround the outside of the column core 8. The inner wall of the regulating tube 7 is fixedly connected with multiple evenly distributed spoilers 701. Through the above arrangement, the pure water 10 can be interfered with, thereby avoiding the generation of large vortices after the pure water 10 rotates, which excessively affects the liquid level height of the pure water 10 in the regulating tube 7.

[0030] Second implementation method:

[0031] Figure 4-8A pressure self-balancing drip irrigation pipe fitting for mountainous areas is shown. Different from the first embodiment, the side wall of the regulating pipe 7 is fixedly connected to an equipment box 12, the top of the equipment box 12 is fixedly connected to a spare box 11, and the inner wall of the equipment box 12 is fixedly connected to a liquid pump 13. The input end of the liquid pump 13 is connected to the spare box 11, and the output end of the liquid pump 13 is connected to the regulating pipe 7. The volume of the spare box 11 is the same as that of the regulating pipe 7, and the volume of the pure water 10 is the same as that of the spare box 11; the liquid pump 13 can pump the pure water 10 inside the regulating pipe 7 into the inside of the spare box 11, and can pump the pure water 10 inside the spare box 11 into the inside of the regulating pipe 7, so as to change the liquid level of the pure water 10 in the regulating pipe 7. When the opening amplitude of the resistance plate 9 is the same, the higher the liquid level, the greater the resistance to the rotation of the resistance plate 9, and vice versa. Through the above arrangement, the flow rate of the water flow can be further adjusted according to the size of the terrain drop or the spacing between multiple drip irrigation pipes 3.

[0032] An electric power box 14 is fixedly connected between the top of the regulating tube 7 and the side wall of the standby box 11, a coupling 16 is fixedly connected to the top of the column core 8, a micro-generator 15 is fixedly connected to the inner wall of the top of the electric power box 14, and a battery 17 is fixedly connected to the inner wall of the equipment box 12. The top of the coupling 16 extends to the inner side of the electric power box 14 and is fixedly connected to the rotating end of the micro-generator 15. The output end of the micro-generator 15 is electrically connected to the battery 17, and the battery 17 is electrically connected to the liquid pump 13 and the solenoid valve 301; when the column core 8 rotates, the rotating end of the micro-generator 15 can be driven to rotate through the coupling 16, and the micro-generator 15 can generate electricity and store it in the battery 17. Through the above arrangement, the power of the rotation of the column core 8 can be utilized, and the liquid pump 13 can generate electricity to charge the battery 17, thereby avoiding energy waste and providing power for driving the solenoid valve 301 and the liquid pump 13.

[0033] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
