[0002] Agricultural irrigation is crucial for ensuring crop growth and increasing agricultural yields. With the advancement of science and technology, modern irrigation technology has evolved from traditional surface irrigation to highly efficient, water-saving irrigation. By manually controlling the timing and volume of irrigation, water utilization efficiency is improved.

In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0031] Example 1

[0032] like Figure 1-8As shown, this embodiment provides a pressure-adjustable water supply power source device, including a water pump 1 for pumping water and a pressure-regulating structure 3 for adjusting the water outlet pressure. The water pump 1 and the pressure-regulating structure 3 are connected by an input water pipe 2. The pressure-regulating structure 3 includes a shell 4, a central water pipe 5 is horizontally arranged inside the shell 4 and is sealed with the shell 4, a pressure-regulating component 8 is installed on the top of the front end of the central water pipe 5, and a pressure-relief component 9 is installed on the bottom of the rear end of the central water pipe 5. By setting the pressure-regulating structure 3, the water discharged from the input water pipe 2 through the pressure-regulating structure 3 can be adjusted by the pressure-regulating Structure 3 adjusts the water pressure so that the water pressure used for irrigation can adapt to the irrigation of different crops, effectively avoiding the situation where the surface soil covering the roots of crops is washed away due to excessive water flow, thereby affecting the growth of crops. By setting the pressure regulating component 8 and the pressure relief component 9, when in use, driving the pressure regulating component 8 can reduce the water pressure at the front port of the central water pipe 5. If the water pressure in the central water pipe 5 is too low, driving the pressure relief component 9 can increase the water pressure at the rear port of the central water pipe 5, thereby achieving the purpose of stabilizing the irrigation water pressure, achieving the purpose of uniform irrigation, and further improving the irrigation effect.

[0033] The shell 4 is a cylindrical structure with small ends and large middle, and the two ends of the shell 4 are closed structures. The side walls of the shell 4 are fixedly connected with brackets. The shell 4 can be stably placed on the carrier through the brackets. At the same time, the shell 4 can determine the positions of the pressure regulating component 8 and the pressure relief component 9 installed inside the shell 4 through the brackets, so that the pressure regulating component 8 can be used normally. A front partition 11 is fixedly connected to one side of the front end face of the shell 4, and a front water chamber 12 is formed between the front end face of the shell 4 and the front partition 11. A rear partition 13 is fixedly connected to one side of the rear end face of the inner wall of the shell 4, and a rear water chamber 14 is formed between the rear end face of the shell 4 and the rear partition 13. An external water inlet 15 is provided in the middle of the front end face of the shell 4, and an external water outlet 18 is provided in the middle of the rear end face of the shell 4. An inner water inlet 16 is provided in the middle of the partition 11, and an inner water outlet 17 is provided in the middle of the rear partition 13. The outer water inlet 15, the inner water inlet 16, the inner water outlet 17 and the outer water outlet 18 are all coaxial circular holes, and the inner side walls of the outer water inlet 15, the inner water inlet 16, the inner water outlet 17 and the outer water outlet 18 are all provided with sealing grooves 23. The cavity formed between the front partition 11 and the rear partition 13 is called a water storage chamber 10. By setting up the water storage chamber 10, when the water inlet pressure of the central water pipe 5 is too high, water can be stored through the water storage chamber 10 to temporarily store excess water, and when the water outlet pressure of the central water pipe 5 is too low, the water stored in the water storage chamber 10 is discharged, thereby increasing the water outlet pressure of the central water pipe 5, thereby ensuring the stability of the water pressure during irrigation.

[0034] The front baffle 11 is provided with an adjustment hole 20, which is above the inner water inlet 16. The front baffle 11 is provided with a pressure reducing notch 19, which is located obliquely above the inner water inlet 16. The pressure reducing notch 19 is an arc-shaped through-groove structure and its arc-shaped central axis is coaxial with the adjustment hole 20. The inner wall of the pressure reducing notch 19 is provided with a sliding slot 29. By providing the pressure reducing notch 19, the water storage chamber 10 stores water through the pressure reducing notch 19, thereby reducing the water inlet pressure of the central water pipe 5, and cooperating with the pressure regulating component 8 can control the water inlet pressure of the central water pipe 5, thereby realizing the water pressure adjustment function during irrigation. A pressure relief slot 21 is provided on the rear partition 13. The pressure relief slot 21 is an arc-shaped through slot structure and its arc-shaped central axis is coaxial with the inner water outlet 17. A limiting slide groove 22 is provided on the inner wall of the rear water accumulation chamber 14. By setting the pressure relief slot 21 and cooperating with the function of the pressure relief component 9, the discharge of water stored in the water storage chamber 10 can be controlled, which facilitates the balance of the water outlet pressure of the central water pipe 5 and ensures the stability of the irrigation water pressure.

[0035] The pressure regulating assembly 8 includes a first blocking block 24 embedded in the pressure reducing slot 19, and the outer wall of the first blocking block 24 is fixedly connected with a sliding card strip 30 adapted to the sliding card slot 29. The first blocking block 24 is an arc-shaped keyway structure, and its arc length is less than the arc length of the pressure reducing slot 19. When the first blocking block 24 is installed in the pressure reducing slot 19, the sliding card strip 30 is embedded in the sliding card slot 29 so that the first blocking block 24 slides and is connected to the pressure reducing slot 19, and plays a guiding role for the first blocking block 24. The first blocking block 24 can partially block the pressure reducing slot 19, adjust the position of the first blocking block 24 in the pressure reducing slot 19, and thereby change the height of the water flow entering the water storage chamber 10. According to the water pressure calculation formula, the higher the height of the water flow entering the water storage chamber 10, the higher the water pressure at the front end of the central water pipe 5, thereby achieving the purpose of changing the water pressure in the central water pipe 5. The inner wall of the first blocking block 24 is fixedly connected with a first connecting Rod 25, the other end of the first connecting rod 25 is fixedly connected with a rotating shaft 26, and the first blocking block 24 is embedded in the adjusting hole 20 through the rotating shaft 26 and is rotatably connected to the front partition 11. The pressure regulating assembly 8 also includes a second connecting rod 27 embedded in the front end cover of the shell 4. The rotating shaft 26 penetrates the front partition 11 and the front end cover of the shell 4 and is fixedly connected to the second connecting rod 27. The outer side wall of the rotating shaft 26 is provided with multiple groups of positioning slots 28, and the adjusting hole 20 is provided with a positioning block adapted thereto. When the rotating shaft 26 is installed in the adjusting hole 20, the locking block is embedded in one group of positioning slots 28 to lock the rotating shaft 26 to prevent it from rotating at will. When the position of the first blocking block 24 needs to be adjusted, a certain external force needs to be applied to the second connecting rod 27 to drive the rotating shaft 26 to rotate in the adjusting hole 20, so that the positioning block enters the next group of positioning slots 28. When the rotating shaft 26 rotates, the first blocking block 24 will rotate synchronously.

[0036] The pressure relief assembly 9 includes a second blocking block 31 adapted to the pressure relief slot 21. The cross-section of the second blocking block 31 is an L-shaped structure. After being connected with the pressure relief slot 21, it can slide in the pressure relief slot 21. After the second blocking block 31 is moved to a suitable position, the pressure relief slot 21 can be completely blocked. When the second blocking block 31 is staggered, the pressure relief slot 21 is opened, and the water flow in the water storage chamber 10 can be discharged through the pressure relief slot 21. One end of the second blocking block 31 is fixedly connected to a third connecting block with an arc structure. The connecting rod 32 and the third connecting rod 32 are adapted to the limiting slide groove 22. The other end of the third connecting rod 32 is rotatably connected to the floating plate 33. When the pressure relief assembly 9 is installed in the shell 4, the second blocking block 31 slides and is embedded in the pressure relief slot 21. The third connecting rod 32 is embedded in the limiting slide groove 22 and guides the second blocking block 31. The floating plate 33 can be lifted by the buoyancy of the water. When the water level in the rear water accumulation chamber 14 is high, the floating plate 33 can be lifted, thereby driving the second blocking block 31 to rotate to the maximum The third connecting rod 32 is limited in its movable space due to the limitation of the limiting chute 22. If the water level in the rear water chamber 14 is too high, the floating plate 33 will be submerged. When the water level in the rear water chamber 14 drops to a lower point, the floating plate 33 begins to drop and drives the second blocking block 31 to move, opening the blocked pressure relief slot 21. The water in the water storage chamber 10 is replenished into the rear water chamber 14 to ensure that the water outlet pressure of the central water pipe 5 is stable. The two ends of the central water pipe 5 are respectively fixedly connected with connecting heads 6, and the two ends of the central water pipe 5 are respectively installed to the inside of the internal water inlet 16 and the internal water outlet 17 through the connecting heads 6. A sealing ring 7 is provided on the outer side of the connecting head 6, and the sealing ring 7 is adapted to the sealing groove 23 structure. When the connecting head 6 is installed to the corresponding internal water inlet 16 and the internal water outlet 17, the sealing ring 7 is embedded in the sealing groove 23, and the sealing ring 7 greatly increases the sealing between the connecting head 6 and the internal water inlet 16 or the internal water outlet 17.

[0037] Working steps

[0038] Step 1. When in use, connect the water pump 1 and the pressure regulating structure 3 through the input water pipe 2, the water inlet end of the water pump 1 is connected to the water source, and the water outlet end of the pressure regulating structure 3 is connected to the irrigation water pipe and extended to the farmland. After the water pump 1 is started, the water in the water source is pumped out through the input water pipe 2 into the pressure regulating structure 3, and then irrigated from the water outlet end of the pressure regulating structure 3 through the water pipe to the farmland to complete irrigation. The water outlet end of the input water pipe 2 is installed in the external water inlet 15, and the water inlet end of the irrigation water pipe is installed in the external water outlet 18. The water flows into the front water accumulation chamber 12 from the external water inlet 15 until the water level line crosses the lowest point of the internal water inlet 16 and then enters the central water pipe 5, and then is injected into the rear water accumulation chamber 14 from the other end of the central water pipe 5 until the water level line crosses the lowest point of the internal water outlet 17 and then enters the irrigation water pipe.

[0039] The average water pressure of the water pump should be able to make the water level in the front water chamber 12 reach the highest point of the internal water inlet 16. When the water pressure of the water pump increases, the water level in the front water chamber 12 rises, and the water pressure in the central water pipe 5 increases at the same time, and the impact force of the water flow used for irrigation is enhanced; when the water pressure of the water pump decreases, the water level in the front water chamber 12 decreases, and the water pressure in the central water pipe 5 decreases at the same time, and the impact force of the water flow used for irrigation is reduced.

[0040] Step 2: Since the first blocking block 24 cannot completely close the pressure relief notch 19, there is always a gap in the pressure relief notch 19. When the water level in the front water chamber 12 is at the gap of the pressure relief notch 19, the set maximum water pressure is reached. When the water level in the front water chamber 12 exceeds the gap of the pressure relief notch 19, the excess water flows into the water storage chamber 10, maintaining the water pressure in the central water pipe 5 constant. The capacity of the water storage chamber 10 is sufficient to store the water overflowed by the water pump in a short time. At the same time, the water level in the rear water chamber 14 is It should drive the float plate 33 to float up and drive the second blocking block 31 to completely block the pressure relief slot 21; when the water pressure of the water pump is too low, causing the water level in the rear water storage chamber 14 to be lower than the highest point of the inner water outlet 17, the float plate 33 moves downward and drives the second blocking block 31 to move to open the pressure relief slot 21, and the water stored in the water storage chamber 10 will be discharged from the pressure relief slot 21 to the rear water storage chamber 14, and replenished until the water level reaches the highest point of the rear partition 13, thereby stabilizing the outlet water pressure of the central water pipe 5 and maintaining the stability of the water pressure in the irrigation water pipe.

[0041] Step 2. The position of the first blocking block 24 can be adjusted by rotating the second connecting rod 27. When the second connecting rod 27 is rotated counterclockwise, the second connecting rod 27 rotates and drives the first connecting rod 25 to rotate synchronously through the rotating shaft 26, and adjusts the first blocking block 24 to the lowest point of the pressure reducing slot 19. When the first blocking block 24 is located at the lowest point of the pressure reducing slot 19, the gap of the pressure reducing slot 19 is located at the highest point, and the average water pressure of the central water pipe 5 is larger. When the second connecting rod 27 is rotated clockwise, the first blocking block 24 is adjusted to the highest point of the pressure reducing slot 19. At this time, the gap of the pressure reducing slot 19 is located at the lowest point, and the average water pressure of the central water pipe 5 is smaller, thereby realizing the function of regulating the irrigation water pressure.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
