Description

TECHNICAL FIELD

[0001] The utility model relates to desert control technical field, especially a kind of rainwater collecting and water preserving device. BACKGROUND

[0002] In the Tengger Desert afforestation area of the Yellow River Basin, the problem of poor stability of vegetation system is more prominent, and in some areas, even the phenomenon of community recession and death occurs. This is mainly due to the lack of water resources in the local area, uneven distribution of precipitation intensity in space and time, and poor soil water retention capacity, which makes it difficult to maintain the water needed for normal growth of vegetation.

[0003] The Chinese utility model patent with publication number CN117918174A discloses a plant rainwater collecting and water preserving sand control device and its use method. When planting plants in sandy land for water conservation, sand prevention and sand control, there is a lot of sand in the sandy land. After long-term use, sand will enter the inside of the insertion box from the top of the insertion box. The water absorption performance of the filler layer depends on the pore structure and surface characteristics of its material. When sand is mixed into the filler layer, it will fill the pore space of the filler layer, reducing the ability of the filler layer to absorb water, affecting the water absorption of the filler layer inside the insertion box, and causing the need for regular cleaning of sand inside the insertion box. Cleaning the sand inside requires pulling the insertion box out of the sandy land, which requires a lot of manpower and resources, and is inconvenient.

[0004] The Chinese utility model patent with publication number CN118452030B discloses a plant rainwater collecting and water preserving sand control device. When there is a lot of sand accumulation on the top of the plugging column, the driving mechanism can drive the plugging column to rotate around its own axis. The rotation of the plugging column causes some sand to be discharged with the rotation of the sand collecting groove, thereby avoiding the entry of sand into the water collecting box and affecting the water absorption of the sponge inside the insertion box, and achieving automatic cleaning of sand. However, the A driving assembly, B driving assembly and connecting piece arranged above have complex structure and high cost. UTILITY MODEL CONTENT

The connecting structure of the water collecting part 2 and the water collecting box 1 enables the rainwater collecting area and the storage area to be effectively communicated; the connecting mode of the water guide pipe 3 ensures that the rainwater can be smoothly transmitted from the water collecting surface 23 to the sponge in the water collecting box 1; the sand discharging pipe 4 is communicated with the bottom of the horizontal section of the water guide pipe 3, the sand in the mixed rainwater is deposited in the sand discharging pipe 4 due to gravity by skillfully utilizing the water flow state, and the preliminary separation of sand and water is realized.

[0028] In a preferred embodiment, the water collecting part 2 comprises a water collecting plate 21 and a support frame 22, the bottom of the water collecting plate 21 is fixedly connected with the water collecting box 1 through the support frame 22, the top surface of the water collecting plate 21 is a water collecting surface 23, the water collecting surface 23 is provided with a rainwater collecting opening 24 for communicating with the water guide pipe 3, the combination of the water collecting plate 21 and the support frame 22 provides stable and reliable support for the water collecting surface 23, which can withstand the impact force of rainwater and the influence of external environment, and is not easy to deform or damage; the specific rainwater collecting opening 24 provides a precise connection position for the water guide pipe 3, effectively ensuring that the rainwater flows smoothly from the water collecting plate 21 to the water guide pipe 3, reducing the spilling and loss of rainwater during the transfer process, and improving the rainwater collecting efficiency. The water collecting plate 21 is fixedly connected with the water collecting box 1 by the support frame 22, which not only ensures the accuracy of the position of the water collecting plate 21, but also isolates the erosion of the sand ground to the water collecting surface 23 to some extent, prolonging the service life of the water collecting part 2.

[0029] In a preferred embodiment, the water collecting surface 23 is an arc surface which gradually decreases from the circumferential edge to the position of the rainwater collecting opening 24, the arc surface design can make the rainwater falling on different positions of the water collecting plate 21 naturally converge to the rainwater collecting opening 24 due to gravity, which greatly improves the water collecting efficiency compared with the flat surface design, and reduces the residual and evaporation loss of rainwater on the water collecting plate 21; the rainwater uniformly and smoothly flows to the rainwater collecting opening 24, making the water flow entering the water guide pipe 3 more stable, which is helpful for the orderly transmission of subsequent water flow in the water guide pipe 3 and the whole device.

[0030] In a preferred embodiment, the water guide pipe 3 comprises a vertical pipe 31, a horizontal pipe 32 and an inclined pipe 33, the top end of the vertical pipe 31 communicates with the rainwater collecting opening 24, one end of the horizontal pipe 32 is connected with and communicates with the bottom end of the vertical pipe 31, the bottom of the middle part of the horizontal pipe 32 communicates with the top end of the sand discharging pipe 4, the other end of the horizontal pipe 32 communicates with the top end of the inclined pipe 33, the bottom end of the inclined pipe 33 extends into and communicates with the sponge in the water collecting box 1, the vertical pipe 31 vertically guides the rainwater collected by the rainwater collecting opening 24 downward, which is convenient for efficient transmission of the initial water flow; the horizontal pipe 32 provides a stable horizontal flow channel for the rainwater, and the middle part communicates with the top end of the sand discharging pipe 4, which creates conditions for sand deposition; the setting of the inclined pipe 33 enables the rainwater to enter the sponge in the water collecting box 1 at a suitable angle, avoiding the direct impact of the water flow on the sponge which may cause the structure of the sponge to be damaged, and at the same time, the deepening of the inclined pipe 33 into the sponge is also conducive to more evenly dispersing the rainwater to different parts of the sponge, improving the absorption efficiency of the sponge for rainwater, in addition, when the water stored in the water collecting box 1 is heated and evaporated, the water vapor can only overflow through the inclined pipe 33, and the inclined setting of the inclined pipe 33 can slow down the overflow rate of the steam, block part of the steam overflow, and effectively reduce the evaporation amount of the stored water.

[0031] In a preferred embodiment, the bottom end of the inclined pipe 33 is a closed end, and the inclined pipe 33 is uniformly provided with a plurality of water outlets 34 at a certain interval from the closed end. The design of a closed bottom end and uniformly distributed water outlets 34 changes the way water flows into the sponge. The closed bottom end prevents water from directly impacting the bottom of the water collection box 1, allowing rainwater to slowly infiltrate the sponge through the water outlets 34 more evenly, preventing the sponge from being washed away or causing local waterlogging due to turbulent local water flow. The uniformly distributed water outlets 34 allow rainwater to be more widely distributed across the cross-section of the sponge, enabling each part of the sponge to fully absorb water and improving the overall water absorption efficiency of the sponge, effectively improving the water retention capacity of the device.

[0032] In a preferred embodiment, the top end of the sand discharge pipe 4 is connected to and communicates with the lower semicircle of the horizontal pipe 32, allowing mixed rainwater with sand to enter the sand discharge pipe 4 more naturally and smoothly. Since the lower semicircle of the horizontal pipe 32 is located lower, sand is more easily deposited into the sand discharge pipe 4 under the action of gravity. The flow state of water in the horizontal pipe 32 at this position also helps guide sand into the sand discharge pipe 4, improving the efficiency and accuracy of sand discharge and reducing the likelihood of sand entering the water collection box 1 with the water flow, better protecting the water absorption performance of the sponge in the water collection box 1 from being disturbed by sand.

[0033] In a preferred embodiment, the gravity switch 5 includes a valve plate 51, a rotating rod 52, and a return spring 53. The bottom end of the sand discharge pipe 4 is provided with an adapter seat 41, the rotating rod 52 is rotationally connected to the adapter seat 41, the valve plate 51 is fixedly connected to the rotating rod 52, the return spring 53 is sleeved on the outside of the rotating rod 52, the two ends of the return spring 53 are fixedly connected to the adapter seat 41, and the middle part of the return spring 53 is fixedly connected to the valve plate 51 to enable the valve plate 51 to close the bottom opening of the sand discharge pipe 4. When sand of a designed weight is deposited on the top of the valve plate 51, the valve plate 51 can open the bottom opening of the sand discharge pipe 4 to discharge the sand. This structural design of the gravity switch 5 achieves precise control of the opening and closing of the sand discharge pipe 4. By using the weight of the sand acting on the valve plate 51, when the designed weight is reached, the valve plate 51 overcomes the elastic force of the return spring 53 to rotate around the rotating rod 52, opening the sand discharge pipe 4 to discharge the sand. The entire process does not require complex external power or control devices, and the sand discharge action can be automatically completed by relying on simple gravity and spring mechanical structures, which have high reliability and stability. The design of the return spring 53 ensures that the valve plate 51 can automatically return to the closed position after the sand is discharged, ensuring stable operation and normal functional circulation of the device.

[0034] In a preferred embodiment, the bottom opening of the sand discharge pipe 4 is an inclined opening, the bottom opening of the sand discharge pipe 4 is inclined downward away from one side of the rotating rod 52, and the inclined bottom opening helps the sand to be discharged from the sand discharge pipe 4 more quickly and smoothly under the action of gravity. The inclined direction is away from the rotating rod 52, which avoids the discharged sand from directly impacting the valve plate 51 and affecting the normal work of the valve plate 51, and also makes the sand discharge process more stable and stabilizes the sand discharge performance of the whole device.

[0035] In a preferred embodiment, the top surface of the valve plate 51 is provided with a rubber sealing layer, which can enhance the sealing performance between the valve plate 51 and the bottom opening of the sand discharge pipe 4. When the valve plate 51 is in the closed state, the rubber sealing layer fills the small gap between the valve plate 51 and the sand discharge pipe 4, effectively prevents rainwater from seeping out of the gap, effectively ensures the collection and storage of rainwater in the water collecting box 1, and avoids the problem of reducing the water retention efficiency of the device due to the gap leakage. The rubber has certain flexibility and pressure resistance, can better adapt to the action of the valve plate 51 during the working process of the gravity switch 5, can buffer the impact of the sand on the surface of the valve plate 51, and prolongs the service life of the valve plate 51.

[0036] The principle and implementation mode of the specific examples are described in the utility model, and the above embodiment is only used to help understand the method and core idea of the utility model. Meanwhile, for the general technical personnel in the field, according to the idea of the utility model, the specific implementation mode and application range will be changed. In conclusion, the content of the specification should not be understood as the limitation of the utility model.
