Description

Technical Field

[0001] This utility model relates to the field of greening irrigation technology, and in particular to a water-saving irrigation device suitable for slope greening. Background Technology

[0002] With the continuous advancement of ecological environmental protection and urban greening, slope greening, as an important means of improving the ecological environment and preventing soil erosion, has received increasing attention. Due to their unique topographical conditions, slopes face numerous challenges in irrigation. Water-saving irrigation technology is of paramount importance in slope greening, not only effectively utilizing water resources and reducing waste, but also improving irrigation efficiency and promoting vegetation growth.

[0003] However, many existing irrigation systems have significant flaws in their sprinkler design. One prominent problem is the fixed sprinkler angle, which limits the irrigation to only certain areas of vegetation. In sloping environments, the terrain is highly varied, and vegetation distribution and water requirements differ across locations. Fixed-angle sprinklers cannot flexibly adjust to the actual terrain and vegetation distribution, leading to under-irrigation in some areas and over-irrigation in others. This limitation significantly reduces irrigation efficiency, fails to fully meet the precision irrigation needs of sloping vegetation, and wastes water resources. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the above-mentioned problems with a water-saving irrigation device suitable for slope greening, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a water-saving irrigation device suitable for slope greening, including a placement cover, a water injection pipe arranged along the axial direction of the placement cover, a plurality of annular nozzles arranged inside the placement cover, and a flexible hose arranged on the annular nozzles to maintain communication with the water injection pipe;

[0007] A spring is elastically connected between the upper surface of the annular nozzle and the placement cover. A curved tube is provided on the lower surface of the annular nozzle. An arc-shaped interception part is provided at the top opening of the curved tube, and the arc-shaped interception part is located in the lower half of the spray path of the annular nozzle. A baffle is provided at the bottom opening of the curved tube. A seepage hole is opened at the bottom side of the baffle. When the water inflow at the top opening of the curved tube is greater than the drainage flow at the seepage hole, the weight of the curved tube increases due to the convergence of water flow. The annular nozzle gradually moves downward under the gravity of the curved tube to adjust its spray range.

[0008] As a preferred embodiment of the water-saving irrigation device for slope greening described in this utility model, the concave surface of the arc-shaped interception part is aligned with the annular nozzle, and the distance between the arc-shaped interception part and the annular nozzle is 3-5cm.

[0009] As a preferred embodiment of the water-saving irrigation device for slope greening described in this utility model, the top of the annular nozzle is provided with a limiting rod, which slides through the housing.

[0010] As a preferred embodiment of the water-saving irrigation device for slope greening described in this utility model, a coarse filter screen is inclinedly arranged inside the placement cover, and multiple hoses pass through the coarse filter screen. A waste discharge port is opened on one side of the placement cover.

[0011] As a preferred embodiment of the water-saving irrigation device for slope greening described in this utility model, wherein: a storage box communicating with the inside of the placement cover is provided on one side of the placement cover, and at least five extension pipes are connected to one side of the storage box, and several drip nozzles are opened along the axial direction at the bottom of the extension pipes.

[0012] As a preferred embodiment of the water-saving irrigation device for slope greening described in this utility model, the storage box consists of a box body and a detachable box cover, and a fine filter screen is provided inside the box body.

[0013] The beneficial effects of this utility model are:

[0014] 1. By using an arc-shaped interception section below the annular nozzle, the annular water flow can be partially intercepted, allowing the water to flow into the bend. The flow difference causes the water to converge within the bend, increasing its gravity and thus pressing down on the annular nozzle to change its spray direction. This allows for flexible coverage of different green areas, greatly improving irrigation efficiency and preventing under- or over-irrigation in certain areas. Simultaneously, this precise irrigation mode effectively reduces water waste, significantly improving water resource utilization efficiency while enhancing irrigation effectiveness, demonstrating a significant advantage in water conservation.

[0015] 2. By installing a storage tank connected to the placement cover, water flowing down the slope can be effectively collected. After being filtered through the storage tank, this water is then used for drip irrigation of the slope greening through drip outlets on the extension pipe. This not only avoids unnecessary water loss but also allows the collected water to fully nourish the slope vegetation, greatly improving water resource utilization efficiency and maximizing the irrigation effect of slope greening with a smaller amount of water.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0028] Reference Figures 1-6 This invention provides a water-saving irrigation device suitable for slope greening, comprising a placement cover 1, which is placed on a slope with its side opening facing the slope. The placement cover 1 is provided with a water injection pipe 2 along the axial direction, and the outer end of the water injection pipe 2 is connected to a water pump. Several annular nozzles 4 are provided inside the placement cover 1, and the annular nozzles 4 are provided with flexible hoses 3 that are connected to the water injection pipes 2.

[0029] A spring 5 is elastically connected between the upper surface of the annular nozzle 4 and the placement cover 1. A limit rod 14 is provided at the top of the annular nozzle 4. The limit rod 14 slides through the placement cover 1 and limits the annular nozzle 4 to prevent its position from shifting. When the spring 5 is in its natural state, the annular nozzle 4 maintains the maximum upward angle.

[0030] A bend 6 is provided on the lower surface of the annular nozzle 4. An arc-shaped interception part 61 is provided at the top opening of the bend 6. The concave surface of the arc-shaped interception part 61 is aligned with the annular nozzle 4, and the distance between the arc-shaped interception part 61 and the annular nozzle 4 is 3-5 cm. The arc-shaped interception part 61 is located in the lower half of the spray path of the annular nozzle 4, that is, a small part of the annular water flow below the horizontal plane of the annular nozzle 4. It is used to intercept the water flow that deflects downward and ensure that the intercepted water flow is greater than the seepage flow of the seepage hole 71. A baffle 7 is provided at the bottom opening of the bend 6. A seepage hole 71 is provided at the bottom side of the baffle 7. The diameter of the seepage hole 71 is small, so that the water flow seepage speed is slow.

[0031] When the inlet flow rate of the bend 6 is greater than the drainage flow rate of the seepage hole 71, the bend 6 is controlled by the convergence of water flow, and the overall weight increases. The annular nozzle 4 is controlled by the gravity of the bend 6 and gradually moves downward to adjust its spray range. At the same time, when the annular nozzle 4 moves downward, it will pull the spring 5 to extend. When the water injection pipe 2 stops injecting water, the water in the bend 6 continues to flow outward. When its gravity cannot overcome the tension of the spring 5, the spring 5 drives the annular nozzle 4 to reset.

[0032] like Figure 4 and Figure 5 As shown, a coarse filter screen 8 is inclinedly installed inside the placement cover 1. The coarse filter screen 8 can perform preliminary filtration of the water flow, removing larger impurities or particles to ensure that the water flow for subsequent treatment is relatively clean. Multiple hoses 3 pass through the coarse filter screen 8, and the hoses 3 extend a sufficient distance from the filter screen 8 to ensure that the annular spray pipe 4 can move downward. A discharge port 9 is opened on one side of the placement cover 1 to facilitate the discharge of filtered impurities or waste and avoid the accumulation of impurities. A storage tank 10 connected to the inside of the placement cover 1 is provided on one side of the placement cover 1. At least five extension pipes 12 are connected to one side of the storage tank 10. Several drip ports 13 are opened axially at the bottom of the extension pipes 12. The storage tank 10 consists of a tank body and a removable tank cover. A fine filter screen 11 is installed inside the tank. The fine filter screen 11 can perform secondary fine filtration of the water flow to further remove small particles or impurities and prevent clogging of the drip ports 13. At the same time, the operator can remove the tank cover to clean the fine filter screen 11 regularly.

[0033] When irrigating slopes, due to the slope, the irrigation water in the upper layer will flow down quickly under gravity under traditional irrigation methods. By placing a cover 1 that fits onto the slope, the flowing water can be collected, filtered, and then slowly drip-irrigated to the greenery, achieving a water-saving effect.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
