Description

Technical Field

[0001] This invention relates to the field of environmental protection application technology, specifically to a water collection device with a hydrophilic strip and irregularly shaped ribs for sand control and tree planting. Background Technology

[0002] Constructing sand-control forests can prevent the spread of desertification, and large-scale sand-control forests can also change the local climate. Sand-control forests, established by planting trees in the desert, are a green barrier that reduces the impact of sandstorms on human production and life, which is especially important for cities plagued by sandstorms.

[0003] Even with the selection of tree species with low water requirements, obtaining sufficient water resources for irrigation and shelterbelt planting in deserts and areas being eroded by desert remains extremely difficult. Due to scarce rainfall and a lack of surface water, local water resources are often insufficient to meet water demands, necessitating water diversion from other regions or even groundwater extraction. However, water trucks have limited capacity, transportation costs are high, and large-scale groundwater extraction further damages the fragile local ecosystem. Existing technologies include water collection devices for desert environments, but these are large, complex, and costly, exhibiting significant limitations.

[0004] Afforestation and desertification control are large-scale, long-term projects that require devices that are less expensive, have a simpler and more compact structure, and facilitate water collection. Desert beetles, however, can collect water from the desert environment through the combination of hydrophilic bands and dorsal markings. Based on this, to improve the convenience of water collection devices, we designed a water collection device for desertification control and afforestation that features hydrophilic bands and irregularly shaped ribs. Summary of the Invention

[0005] To address the problems existing in the prior art, the present invention aims to provide a water collection device with a hydrophilic strip and irregularly shaped ribs for sand control and tree planting. This device enables the irrigation water for protective forests to be freed from dependence on externally transported water and groundwater, obtaining moisture from water vapor condensation caused by temperature changes in the desert. Through a portable and simple structure and a working mode that does not require human intervention, it eliminates the dependence of the irrigation process on people and irrigation machines, thereby reducing the cost of sand control and tree planting. The compact structure provides lightweight mobility, while the small footprint allows it to be combined with the straw checkerboard pattern used in desertification control.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A water collection device with a hydrophilic strip and irregular ribs for sand control and tree planting includes a top cover, a water collection unit and a support base. The water collection unit is disposed on the support base and includes several water collection sub-units. The water collection sub-units are connected sequentially along the circumferential direction and multiple layers are stacked between the top cover and the support base. The water collection sub-units between each layer are connected sequentially, so that the middle part of the device has a skeleton structure.

[0008] Furthermore, the water collection subunit includes an upper unit, a lower unit, and a flow channel, with the flow channel located in the middle of the lower unit. The upper and lower units are horizontally shaped ribs, which provide a larger surface area while maintaining structural strength by bending the traditional rib design, resulting in a smaller volume.

[0009] Furthermore, the upper unit and the lower unit are symmetrically arranged, and each upper unit and the lower unit includes several arc-shaped rings, which are arranged in sequence to form a corrugated groove.

[0010] Furthermore, the guide channel is provided with an inward tilt angle, thereby dripping water onto the soil inside the device.

[0011] Furthermore, a nano-hydrophilic coating layer is applied to the arc-shaped ring, so that the contact angle of the droplets in the water collection unit is less than 90°.

[0012] The technical concept of this invention: This invention utilizes the large temperature variations characteristic of desert regions. By relying on the condensation of water vapor in the air during the low temperatures of morning and evening, the water is collected through a water collection unit and channeled into the soil surrounding the device. This irrigates trees planted for sand control, eliminating reliance on externally transported water or groundwater, providing a better living environment for the planted trees, and improving their survival rate. Desert soil is loose, granular, and lacks cohesion. To ensure stability in this soil environment, the device is secured by a support base inserted into the soil. Due to limited vegetation cover, desert regions experience high wind speeds, which can even uproot trees. The water collection device needs to operate in strong winds and may face harsh conditions such as swirling sand and gravel. This invention, by designing the device with a skeletal structure, effectively reduces wind interference. Simplifying the device structure reduces maintenance and operational burdens during long-term operation in desert environments.

[0013] Compared with the prior art, the advantages of this invention are:

[0014] 1) By utilizing the large temperature difference in desert areas through water collection units, water is obtained by relying on the condensation of water vapor in the air during the low temperatures in the morning and evening to irrigate the protective forest, thus avoiding the need for water transportation and groundwater extraction for irrigation.

[0015] 2) It can spontaneously obtain water for irrigation by relying on the temperature difference between morning and evening. Its working mode does not rely on manual labor, electronic equipment and pipelines, thus getting rid of the dependence on manual labor and irrigation equipment in traditional design schemes and reducing operation and maintenance costs.

[0016] 3) The compact design reduces the site requirements and limitations of the water collection equipment, making it more portable and compatible with straw checkerboards used in desertification control.

[0017] 4) By designing the device as a skeleton structure, the interference of wind force when the device collects water outdoors is reduced.

[0018] 5) By modifying the original ribs to serve as the upper and lower units of the water collection unit, the curvature was increased to increase the surface area, making it better suited for liquid condensation and droplet rolling under gravity. Based on the characteristics of the back of insects such as tenebrionid beetles, the design was simplified and a circular protrusion was added, which improved the water collection effect of the device and solved the problem that the traditional rib design was not suitable for working in the outdoor desert environment.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] The operation of this device is illustrated using the nano-hydrophilic coating XZ-GT01 as an example.

[0025] like Figure 1A water collection device with a hydrophilic strip and irregularly shaped ribs is disclosed for use in sand-controlling tree planting. When planting sand-controlling trees in the desert, the device utilizes the temperature difference between morning and evening to condense water from the desert environment to irrigate the trees. It includes an upper cover 1, a water collection unit 2, and a support base 3. The water collection unit 2 consists of an upper unit 201 and a lower unit 202, with a guide channel 203 in the middle of the lower unit. When the device is in a desert environment, the large temperature variation between day and night and the rapid heat loss from the desert surface facilitate water vapor condensation. Since the saturated water vapor content of air is directly related to temperature, in desert areas, the air temperature is low in the morning and evening, and its saturated water vapor content is also low, reducing the air's water storage capacity. Moisture in the air begins to condense and precipitate. Furthermore, the coating of the annular protrusions of water collection unit 2 with XZ-GT01 as a hydrophilic layer further promotes water vapor condensation. Initially, small water droplets form on water collection unit 2, which gradually grow larger. Because water collection unit 2 is composed of curved ribs, divided into upper unit 201 and lower unit 202, this design maximizes surface area for a compact and robust structure. The small water droplets formed in upper unit 201, due to their small size, are held in place by the adhesion between them and the solid wall. However, as the condensation process continues, the small water droplets grow larger, and the adhesion between them and the solid wall becomes insufficient to resist gravity, causing them to fall onto lower unit 202. Like the upper unit 201, the lower unit 202 has corrugated grooves formed by arranged annular protrusions on its surface. This increases the contact area with air, promoting water vapor condensation. The curved design of the lower unit 202 causes water droplets to condense on a local slope, inducing flow under the influence of gravity. The condensed water droplets flow along the fine grooves on the corrugated grooves. During this flow, small water droplets merge, develop, and grow with other droplets, creating a carrying effect. Water droplets falling from the upper surface further promote this process. These corrugated grooves formed by the arranged annular protrusions promote the formation and development of water droplets and prevent them from merging to form a liquid film. A liquid film with poor fluidity will cover the water collection unit 2, thus inhibiting further water vapor condensation. The water droplets move under the influence of gravity and reach the guide channel 203 in the middle of the lower unit 202, thus dripping onto the large soil inside the device. This completes the collection of moisture from the air, increases the moisture content of the shelterbelt soil, improves the soil quality, and increases the survival rate of the shelterbelt.

[0026] To meet the requirements of outdoor work in desert environments, the device is designed as a hollow tube with a skeletal structure, reducing the windward area and thus minimizing the impact of wind and sand erosion. This makes the device more durable and reduces subsequent maintenance costs. The top cover 1 further reduces wear and tear caused by sand entering the device. Given the loose, granular, and poorly cohesive nature of desert soil, a water collection device with hydrophilic strips and irregularly shaped ribs for sand control and tree planting is easily fixed in the sand via a support base 3, preventing the device from being blown away by sand during operation. This effectively meets the requirements of sand control and tree planting work environments.

[0027] A water collection device with a hydrophilic strip and irregularly shaped ribs, designed for sand control and tree planting, is easy to move and use. Its working principle utilizes the large temperature differences characteristic of desert regions, liquefying and collecting moisture from the air to provide irrigation water for shelterbelts in desert areas. This reduces water costs and alleviates the pressure of water transportation and groundwater extraction. It obtains water based on the temperature difference between morning and evening, and its operation is independent of manual labor, electronic equipment, and pipelines, eliminating the dependence on manual labor and irrigation equipment in traditional designs and reducing operating and maintenance costs. This invention, with its simple structure and ease of use, is of great significance in alleviating the water shortage problem in shelterbelts.

[0028] The above are merely preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
