DETAILED DESCRIPTION

[0037] In order to further explain the technical means and effects taken by the utility model to achieve the predetermined purpose, the specific implementation, structural features and effects of the utility model are described in detail as follows in combination with the drawings and examples.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0039] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "aligned", "overlapping", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0040] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0041] To reduce water waste caused by rapid evaporation and avoid discomfort caused by excessive local humidity due to the accumulation of large amounts of water vapor, this embodiment provides a... Figure 1 The water-saving device shown is suitable for greening irrigation. It includes a ground-inserted sprinkler 1, characterized in that it also includes a ground cage network assembly composed of multiple ground cages 2. The ground-inserted sprinkler 1 is fixed at the geometric center of the ground cage network assembly (in practice, it is the geometric center of a certain ground cage network assembly, because multiple ground cage network assemblies are selected according to the size of the plot to cover as much plot area as possible and achieve full-area irrigation of the plot. Generally, according to the setting of the sprinkler coverage radius, multiple networked ground cage network assemblies are selected to form a block-type sprinkler surface coverage. Therefore, the total area of ​​the block-type ground cage network assembly is less than the area of ​​the irrigated plot. As long as its sprinkler area can cover or is slightly larger than the area of ​​the irrigated plot, it is acceptable), so as to achieve uniform and full-coverage irrigation and spraying in all directions.

[0042] And the second cage is Figure 2 The regular polyhedron shown is preferably a regular dodecahedron, similar to the structure of a soccer ball. This design allows for easy connection and networking of adjacent traps (e.g., Figure 1As shown, the connection network of the ground cage, i.e. the ground cage network component 19, is formed by a plurality of ground cages 2 connected in a honeycomb shape with adjacent edges. At the same time, a larger containing cavity can be obtained, thereby having a larger water storage space to collect more water. Based on this design concept, at least one side of the ground cage 2 is provided with an opening 3

[0043] ( Figure 2 The top of the opening 3 is provided with at least one condensing sheet 4. The condensing effect of the condensing sheet is fully utilized to achieve partial condensation of the water vapor evaporated at high temperature back to the water storage cavity of the ground cage 2. Part of the water vapor that is scattered and overflowed will be condensed under the blocking and low temperature effect of the stems and leaves of the surrounding green plants such as the timothy grass, and will be attached to provide water supply for the green plants. The water condensed back to the water storage cavity of the ground cage 2 will slowly evaporate at low temperature, and will be recycled to the stems and leaves of the surrounding grasses to achieve the effects of water supply and temperature control. Compared with the direct evaporation of the prior art, the evaporation and loss of water vapor are greatly reduced or slowed down, and the effective water supply time and effect for the green plants are prolonged, and the temperature control effect for the green plants is significantly improved.

[0044] The condensing sheet 4 is fixedly connected to the inner edge of the opening 3 through a plurality of connecting sheets 5, and the plurality of connecting sheets 5 are arranged in an overlapping manner in the adjacent part, i.e. inclined and sequentially arranged, which is also to increase the area for intercepting water vapor.

[0045] As described above, the ground cage 2 is provided with Figure 3 The water storage component 6, such as a sponge block or a water-absorbing cotton block, is arranged in the ground cage 2 as shown, which is used to absorb the water flowing into the opening 3 when spraying, and to block and slow down the evaporation of water at high temperature after spraying.

[0046] The number of condensing sheets 4 is further set to two in this embodiment, and the two condensing sheets 4 are arranged in a vertical direction in a stacked and staggered manner. The outer edges of each condensing sheet 4 away from each other are fixedly connected to the inner edge of the opening 3 through the connecting sheets 5. Each condensing sheet 4 is arranged in an inclined downward manner from outside to inside, thereby forming a water guiding effect to the center. The double-layer arrangement of the condensing sheets 4 can further improve the condensation and reflux effect of water vapor, greatly reduce and slow down the evaporation of water, and prolong the partial evaporation and loss of water collected in the ground cage 2 on the surrounding green plants and the partial condensation and reflux. Thus, the water is effectively used on the green plants as many times as possible, the water shortage time of the green plants is shortened, the irrigation frequency is reduced, and the water saving purpose is achieved.

[0047] In this embodiment, at least three condenser plates 4 are provided, which are fan-shaped and arranged circumferentially in an alternating manner. They are inclined downward from the outside to the inside, converge toward the axis, and leave a gap at the axis. The outer edge of each condenser plate 4 is fixedly connected to the inner edge of the opening 3 through a connecting piece 5.

[0048] The condenser plate 4 involved in the above embodiments can be comb-shaped or snowflake-shaped, which increases its hydrophobic and flow-guiding properties and ensures that it has a large condensation surface, so as to achieve rapid condensation and reflux of water vapor.

[0049] Depend on Figure 3 As can be seen, at least one fluffy hydrophobic element is provided inside the opening 3, which is located between the condenser plate 4 and the water storage element 6. The fluffy hydrophobic element is composed of a fixing ring 17 fixedly connected to the inner wall of the opening 3 and multiple mesh sheets 18 fixed at both ends to the opposite inner walls of the fixing ring 17. Similarly, in order to facilitate the drainage, the mesh sheets 18 are inclined, and multiple burrs are provided on the mesh sidewall of the mesh sheets 18 to further increase the drainage and puncture water vapor to enhance the condensation and liquefaction of water vapor.

[0050] Figure 4 The diagram shows the implementation of the ground-inserted sprinkler unit 1 and the ground cage mesh unit 19. The ground-inserted sprinkler unit 1 consists of a ground insert 7, a water guide pipe 8, and at least two nozzles 9 installed at the top of the water guide pipe 8 (commonly three nozzles, arranged in a 120° angle along a ring; the specific number and angle of the nozzles are determined by the spray fan angle of the selected nozzles). The water guide pipe 8 is inserted at the geometric center of the ground cage mesh unit 19 (generally the center of the spray range; installation errors may cause the center of the circle to not completely coincide with the geometric center, in which case the center of the spray range is used as the insertion position). The installation requires the geometric center to coincide with the center of the circle; therefore, the insertion position of the water guide pipe 8 is still based on... (with the geometric center as the limit), this allows for the spraying of the maximum area of ​​green space within the ground cage assembly 19. It should be noted that the ground cage assembly 19 is pre-constructed on the ground surface, and gaps are reserved at the connection points of adjacent ground cages 2 (connected by plastic clips or tied with plastic ties). Green grass (usually mouse grass, which can be transplanted or sown) is planted in these reserved gaps. In this way, the stems and leaves of the green grass are on top, covering the ground cage assembly 19. Mesh openings are made on the bottom side wall of the ground cage 2 (higher than the water storage component 6) for water leakage, guiding the water to the roots and surface of the green grass. Thus, the installation of the ground cage assembly 19 is completed.

[0051] To conserve water, this embodiment provides Figure 4The uniform liquid reducing and diffusing component comprises a top umbrella 10, a middle umbrella 11 and a bottom umbrella 12; the top center of the top umbrella 10 is fixed on the top end of the water guide pipe 8 above the nozzle 9 by a fixed sleeve 13 to cover the nozzle 9; the top umbrella 10 is fixedly connected with the top section of the water guide pipe 8 below the nozzle 9 by a plurality of first inclined struts 14 arranged uniformly in the circumferential direction at the position one third of the distance from the top center of the top umbrella 10; the top of the middle umbrella 11 is an annular opening 20, and the inner edge of the annular opening 20 is fixedly connected with the lower section of the water guide pipe 8 by a plurality of second inclined struts 21 arranged uniformly in the circumferential direction.

[0052] The top ends of a plurality of first vertical rods 15 arranged uniformly in the circumferential direction extend upwardly and are fixedly connected with the position two thirds of the distance from the top center of the top umbrella 10 after passing through the position one third of the distance from the annular opening 20 of the middle umbrella 11; the middle umbrella 11 is fixedly connected with the first vertical rods 15 by binding; the top center hole of the bottom umbrella 12 is bound on the lower section of the water guide pipe 8 below the second inclined struts 21; the top of the bottom umbrella 12 is fixedly connected with the top of a plurality of second vertical rods 16 arranged uniformly in the circumferential direction at the position two thirds of the distance from the water guide pipe 8, and the top of the bottom umbrella 12 is also provided with an annular hole 23.

[0053] The adjacent top umbrella 10, middle umbrella 11 and bottom umbrella 12 are connected by a framework 22.

[0054] The water sprayed by the spray head 9 is blocked by the top umbrella surface 10 and dispersed and falls around, part of which falls on the bottom umbrella surface 12 through the annular opening 20, and part of the water flow sprayed on the bottom umbrella surface 12 is sprayed around the roots of the green grass through the annular hole 23, and part is guided to the outside by the bottom umbrella surface 12. In the process of guiding to the outside, part of the water flow falls to the ground surface through the mesh holes on the bottom umbrella surface 12. Similarly, the water flow sprayed on the middle umbrella surface 11 by the reflection of the top umbrella surface 10 is guided to the outside by the middle umbrella surface 11. Similarly, in the process of being guided to the outside, part of the water flow falls on the bottom umbrella surface 12 and the green grass outside the bottom umbrella surface 12 through the mesh holes on the middle umbrella surface 11. Thus, the layered guiding and external spraying of the water flow is realized, and the controllable range of the spraying operation of each ground-inserting water spraying element 1 is effectively controlled, especially avoiding the overlapping of the spraying edges of adjacent ground-inserting water spraying elements 1 caused by the existing unobstructed spraying, which causes local waterlogging, excessive irrigation of the green plants in the area, and impact of the sprayed water on the skin of the green plants and the concave pits on the ground surface, causing the green plants to be down. By means of the uniform liquid evaporation reduction guide, the evaporation and loss of water can be effectively reduced at high temperatures. With the cooperation of the umbrella surfaces and the ground cage, the condensation and reflux of water vapor are further realized, and with the help of the umbrella surfaces, frameworks, inclined supports and other components of the lower layer, the layered guiding of the condensed and refluxed water is effectively realized, which realizes relatively uniform and large-area spreading on the green plants in the area, avoids concentrated reflux, and helps the uniform absorption of the green plants, avoiding the occurrence of local green plants drought and waterlogging in the prior art.

[0055] Finally, it should be particularly noted that the spacing of each layer of umbrella surface is preferably between 15 and 30 cm, which ensures good ventilation and facilitates heat dissipation (although this will also cause part of the water to be lost, but better ventilation is necessary), avoiding the concentration of heat causing high temperature scalding of the green plants.
