Description

Technical Field

[0001] This application relates to the technical field of irrigation pipelines, and in particular to a water-saving irrigation pipeline structure. Background Technology

[0002] Drip irrigation is one of the more common water-saving irrigation technologies, which delivers water drop by drop to the vicinity of plant roots through drippers. Micro-sprinkler irrigation sprays water onto crops in a mist form using micro-sprinklers. Although micro-sprinkler irrigation saves more water than flood irrigation, in some arid and hot regions, the water remains in the air for a longer period due to the mist, resulting in some evaporation loss. Furthermore, both technologies have limitations; drip irrigation and micro-sprinkler irrigation have relatively small irrigation areas, suitable for plants with well-defined distributions. However, these methods are less effective for situations involving trees, shrubs, and ground cover plants. Continuous use of sprinkler irrigation also leads to some water waste. Therefore, to address these issues, this application provides a water-saving irrigation pipeline structure. Utility Model Content

[0003] To address the limitations of existing drip irrigation and micro-sprinkler systems, this application provides a water-saving irrigation pipeline structure.

[0004] This application provides a water-saving irrigation pipeline structure, including a water supply pipe, a connecting pipe disposed at a separation position of the water supply pipe, a spray pipe disposed directly above the connecting pipe, a spray nozzle disposed at the top of the spray pipe, and the bottom end of the spray pipe being connected to the connecting pipe via a flexible hose. A frame structure is fixed on the connecting pipe to enable the spray pipe to move along an arc-shaped path.

[0005] By controlling the water pressure in the water supply pipe, the position of the sprinkler pipe is adjusted. When the water pressure in the water supply pipe is at the initial water pressure, the sprinkler pipe remains horizontal and drip irrigation is performed at the sprinkler nozzle. When the water pressure in the water supply pipe increases, the sprinkler pipe rotates from horizontal to vertical and water is sprayed from the sprinkler nozzle.

[0006] By applying different pressure values ​​to the water pipes, different irrigation effects can be achieved, and the state of the sprinkler pipes can be changed. When the water pressure increases, the sprinkler pipes stand up and spray in an umbrella shape, which can improve the watering effect on the surrounding plants. When the water pressure decreases, the sprinkler pipes fall down and drip irrigation is carried out, which reduces losses while ensuring basic water needs are met.

[0007] Preferably, the frame structure includes two parts: a track and a support rail. The track and the support rail are arranged concentrically and equidistantly, forming a hollow channel between them.

[0008] Preferably, two tracks and two support tracks are provided, with the front view of the track being 1 / 4 of the arc length, and the ends of the two tracks are fixedly connected to a limiting section.

[0009] Preferably, a collar is fitted at the bottom end of the spray pipe, and a movable shaft is provided on the collar that slides into the hollow channel of the track and support rail.

[0010] Preferably, two support seats are symmetrically arranged below the connecting pipe, and a horizontal strip-shaped through groove is opened at the upper end of each support seat. The two support seats are fixed to the connecting pipe by fastening rings.

[0011] Preferably, both ends of the connecting pipe have sliding locking fasteners, and the two sections of the connecting pipe are fastened to the water supply pipes at both ends by the locking fasteners.

[0012] Preferably, a guide plate is provided on the water supply pipe below the spray nozzle of the spray pipe.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] By applying different pressure values ​​to the water pipes, different irrigation effects can be achieved, and the state of the sprinkler pipes can be changed. When the water pressure increases, the sprinkler pipes stand up and spray in an umbrella shape, which can improve the watering effect on the surrounding plants. When the water pressure decreases, the sprinkler pipes fall down and drip irrigation is carried out, which reduces losses while ensuring basic water needs are met. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 1 - Figure 3 This application will be described in further detail.

[0020] Example 1:

[0021] A water-saving irrigation pipe structure, referring to Figure 1 - Figure 3A connecting pipe 2 is installed at the dividing position of the water supply pipe 1. Both ends of the connecting pipe 2 are fitted with sliding locking fasteners 3. The two sections of the connecting pipe 2 are fastened to the water supply pipes 1 at both ends by the locking fasteners 3. A spray pipe 4 is installed directly above the connecting pipe 2. The top of the spray pipe 4 is equipped with a spray nozzle 41. The bottom end of the spray pipe 4 is connected to the connecting pipe 2 through a flexible hose 5. A frame structure is fixed on the connecting pipe 2 to allow the spray pipe 4 to move along an arc-shaped path. The frame structure includes two parts: a track 6 and a support rail 7. The track 6 and the support rail 7 are set concentrically and equidistantly, forming a hollow channel between them. Two tracks 6 and two support rails 7 are provided. The front view of the track 6 is 1 / 4 of the arc length. The ends of the two tracks 6 are fixedly connected to the limiting section 61. The function of the limiting section 61 is to provide certain support and restriction to the position of the spray pipe 4 after it moves into place, so as to prevent it from moving too far. The spray pipe 4 and the limiting section 61 are in a vertical position when they are in contact.

[0022] A collar 42 is fitted at the bottom end of the spray pipe 4. A movable shaft 421 is provided on the collar 42 and is slidably embedded in the hollow channel of the track 6 and the support rail 7. The movable shaft 421 is positioned off the axis of the spray pipe 4 and is located on the side away from the limiting section 61. The purpose is that when the water pressure of the water supply pipe 1 decreases, the movable shaft 421 acts as the fulcrum of the spray pipe 4 and is always biased to the side of the initial position. Under the action of the gravity of the spray pipe 4 itself, the spray pipe 4 eventually returns to the horizontal position.

[0023] By controlling the water pressure in water pipe 1 and adjusting the position of sprinkler pipe 4, when the water pressure in water pipe 1 is at its initial level, sprinkler pipe 4 remains horizontal, and sprinkler nozzle 41 drips water. When the water pressure in water pipe 1 increases, sprinkler pipe 4 rotates from horizontal to vertical, and sprinkler nozzle 41 sprays water. This problem can be analyzed from the following aspects: 1. Bernoulli's principle: In an ideal fluid, the pressure decreases where the velocity increases. If the water pressure in the lower pipe increases, the water velocity will also increase. 2. Continuity equation: In the absence of flow loss, the flow rate of a fluid in a pipe is constant. This means that if the flow rate in the lower pipe increases, the flow rate in the upper pipe must also increase accordingly to maintain continuity. 3. Soft parts: The soft parts of the upper pipe can deform under water pressure. When the water pressure in the lower pipe increases, the soft parts will be pushed away by the water pressure, straightening from a bend. 4. Gravity and friction: When the weight of the upper pipe and the frictional force in contact with the lower pipe are insufficient to resist the force brought by the increased water pressure in the lower pipe, the upper pipe will be pushed up. In summary, if the water pressure in the lower pipe is high enough, it is possible for the upper pipe to stand upright under that pressure. The required water pressure can be flexibly set after testing, depending on the actual needs of different usage environments. Because it is related to many influencing factors, it is not a fixed value.

[0024] Two support seats 8 are symmetrically arranged below the connecting pipe 2. Horizontal strip-shaped through grooves 81 are opened at the upper end of each support seat 8. The two support seats 8 are fixed to the connecting pipe 2 by fastening rings 9. The purpose of setting the support seats 8 is to ensure that the sprinkler pipe 4 is located directly above the water pipe 4, since the water pipe 1 may be made of soft material and its angle and direction restrictions on the connecting pipe 2 are insufficient. If the water pipe 1 is made of rigid steel pipe or other materials, the support seat 8 structure may not be set. The support seats 8 are provided with through holes for the insertion of steel nails or other materials into the ground to ensure their positional stability.

[0025] A guide plate 10 is installed on the water supply pipe 1 below the spray nozzle 41 of the sprinkler pipe 4. The function of the guide plate 10 is to reduce the corrosion of the pipe by the water flow and to guide the water flow. The shape of the guide plate 10 can be customized later. It guides the drip irrigation water flow to other locations through the guide channel, thereby realizing irrigation for other locations and avoiding the problem of poor drip irrigation effect due to the distance between the water supply pipe 1 and the vegetation.

However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, the protection scope of which is determined by the appended claims.
