Description

Technical Field

[0001] This utility model belongs to the technical field of agricultural and forestry irrigation equipment, specifically relating to a drought-resistant water supply device for agricultural and forestry use. Background Technology

[0002] Arid regions are characterized by dry climates, high evaporation rates, scarce rainfall, and severe water scarcity. Against this backdrop, traditional afforestation techniques have long faced the challenges of high water consumption and costs, hindering effective vegetation restoration and reconstruction. Especially in the early stages of seedling planting, due to their shallow root systems and weak drought resistance, failure to replenish water in a timely manner later in the afforestation process can easily lead to seedling death, further increasing the cost of vegetation restoration.

[0003] Water-absorbing cotton water supply devices, based on the principle of capillary action, have been widely used in home potted plants to achieve a long-term, stable water supply. Their working mechanism lies in the fact that the cotton thread contains countless microfibers forming natural capillary channels. When one end is immersed in water, water molecules, under the combined action of adhesion, cohesion, and surface tension, move upwards along the fiber gaps, thus continuously delivering water to the plant's root zone. This type of device has already been successfully applied in self-absorbing flowerpots and related patents, proving its technical feasibility.

[0004] However, directly applying traditional absorbent cotton water supply devices to afforestation in arid regions presents significant limitations. Firstly, their water supply efficiency is constrained by factors such as the material, diameter, and length of the cotton thread, making it difficult to meet actual water demands over long distances or with large water volumes. Secondly, existing structural designs and material selections fail to adequately consider extreme climatic conditions in arid regions, such as high temperatures, strong winds, and frequent dust storms, leading to increased evaporation of moisture from the cotton thread surface and soil, and a greater water delivery load. In extreme cases, the water delivery rate of the cotton thread may even fail to match the evaporation rate, severely impacting the water supply effect and limiting the large-scale adoption of this technology in arid areas. Utility Model Content

[0005] In view of this, the present invention provides a drought-resistant water supply device for agriculture and forestry to solve the technical problem of poor water supply effect when traditional water-absorbing cotton water supply devices are directly applied to afforestation in arid areas.

[0006] To achieve the above objectives, this application adopts the following approach:

[0007] A drought-resistant water supply device for agriculture and forestry includes a water storage container, a water guiding component, and a water evaporation prevention device. The water storage container and the water evaporation prevention device are detachably connected. The water-drawing end of the water guiding component is located inside the water storage container, and the water-conducting end of the water guiding component extends outward to the target water supply area at the root zone of underground plants. The water evaporation prevention device includes an evaporation suppression sleeve connected to the water storage container and fitted onto the water guiding component to prevent water evaporation from the water guiding component.

[0008] Preferably, the moisture anti-evaporation device includes a hollow cone, the water storage container is connected to the cone of the hollow cone, a plurality of connection ports are provided on the cone surface of the hollow cone, the connection end of the evaporation inhibition sleeve is detachably provided on the connection port, and the water delivery end of the water guide extends outward through the connection port to the target water supply area of ​​the underground plant roots.

[0009] Preferably, the water-guiding component includes a strip of absorbent cotton and a plate-type extension. One end of the strip of absorbent cotton is in contact with the water in the water storage container, and the other end of the strip of absorbent cotton is connected to the plate-type extension. The plate-type extension is located in the target water supply area of ​​the underground plant roots.

[0010] Preferably, the plate extension includes an absorbent cotton plate and two protective mesh plates, the absorbent cotton plate being connected to the water guiding component, and the two protective mesh plates being respectively disposed on the top and bottom of the absorbent cotton plate.

[0011] Preferably, it also includes a water collection device for collecting water.

[0012] Preferably, the water storage container, water guiding component, and water evaporation prevention device are all buried in the underground target water supply area. The water collection device includes a hollow pipe, a first water collection component, and a second water collection component. A section of the hollow pipe is buried underground. One end of the hollow pipe is connected to the hollow cone, and the other end of the hollow pipe is connected to the first water collection component. The first water collection component is located on the ground and is used to collect surface water. The second water collection component is connected to a section of the hollow pipe buried underground and is used to absorb water from the soil. The collected water flows into the water storage container through the hollow cone.

[0013] Preferably, the first water collection component includes a water storage tank, the bottom of which is connected to the hollow tube. A water collection plate is provided on the water storage tank, and the water collection plate has a guide hole and a guide slope to collect water from the edge of the water collection plate towards the center.

[0014] Preferably, the second water collection component includes several water storage rods, which are connected to a portion of the hollow pipe buried underground. The water storage rods are inclined upwards, and the water storage rods form an inclination angle with the portion of the hollow pipe. The water storage rods are provided with absorbent cotton strips inside, and multiple absorbent strip holes are opened on the side wall of the water storage rods.

[0015] Preferably, there are multiple hollow cones connected in series, and the conical surface of any one of the hollow cones is connected to the evaporation suppression sleeve, and the conical part of the bottom hollow cone is connected to the water storage container.

[0016] Preferably, the evaporation suppression sleeve is a flexible tube.

[0017] In the aforementioned drought-resistant water supply device for agriculture and forestry, water storage containers of different capacities are selected according to the degree of drought or size of the plants to ensure sufficient water supply. The water-drawing end of the water guide is placed inside the water storage container, and the water-transmitting end of the water guide extends outward to the target water supply area at the root zone of the underground plants. The evaporation-inhibiting sleeve in the water anti-evaporation device is connected to the conical surface of the hollow cone and is fitted onto the water guide to prevent the water guide from directly contacting the drought-stricken soil. This prevents the water in the water guide from being absorbed by the drought-stricken soil before it is delivered to the target water supply area at the plant roots, and also prevents the water on the water guide from evaporating, thus improving water supply efficiency, reducing water loss caused by evaporation, and greatly improving the efficiency of water resource utilization. It is especially suitable for arid areas or agricultural and forestry planting areas with relatively scarce water resources. The stable water supply can meet the needs of plants at different growth stages, promote the development and growth of plant roots, enhance the drought resistance of plants, improve the survival rate and growth quality of plants, and thus improve the yield and quality of agricultural and forestry crops.

Detailed Implementation

[0024] To facilitate understanding of this application, a more comprehensive description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are also given. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of this application.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] Please refer to Figures 1 to 5 In one specific embodiment, an agricultural and forestry drought-resistant water supply device includes a water storage container 100, a water guide 200, and a water evaporation prevention device 300. The water storage container 100 and the water evaporation prevention device 300 are detachably connected. The water-drawing end of the water guide 200 is located inside the water storage container 100, and the water-conveying end of the water guide 200 extends outward to the target water supply area at the roots of underground plants. The water evaporation prevention device 300 includes an evaporation suppression sleeve 310, which is connected to the water storage container 100 and is sleeved on the water guide 200 to prevent water evaporation from the water guide 200.

[0027] The number of water storage containers 100 can be configured according to actual needs, preferably three. The three water storage containers 100 can be configured with large, medium, and small capacities to accommodate plants of different sizes or different degrees of drought. Multiple water guiding components 200 and water anti-evaporation devices 300 can be provided to meet the need to supply water to multiple target plants simultaneously. The lengths of the water guiding components 200 and water anti-evaporation devices 300 can also be determined according to actual conditions. Preferably, the length of the water guiding component 200 is longer than the length of the water anti-evaporation device 300, so that the water-absorbing end of the water guiding component 200 can be wrapped around the plant roots, improving water supply efficiency.

[0028] When using the drought-resistant water supply device for agriculture and forestry provided in this embodiment, after determining the target water supply area in the agricultural and forestry planting area, select a water storage container 100 of appropriate capacity according to actual needs, install the water guide 200, placing its water intake end inside the water storage container 100 and its water delivery end extending outward to the target water supply area at the root zone of underground plants, ensuring that the water guide 200 can normally transport water from the water storage container 100 to the plant roots. Next, install the water evaporation prevention device 300, first connecting the evaporation suppression sleeve 310 to the water storage container 100, allowing the water guide 200 to pass through the evaporation suppression sleeve 310, so that the evaporation suppression sleeve 310 is fitted onto the water guide 200, completing the installation of the entire device. During subsequent use, water in the water storage container 100 continuously supplies water to the plant roots through the water guide 200. In this embodiment, the water guide 200 and the evaporation suppression sleeve 310 can be buried in the target water supply area, or the water guide 200, the evaporation suppression sleeve 310 and the water storage container 100 can be buried together in the underground target water supply area.

[0029] The water storage container 100 provided in this embodiment can be flexibly configured according to the actual water needs of agricultural and forestry planting. It stores a certain amount of water and transports it to the target water supply area of ​​underground plant roots through the water guide 200, meeting the water needs of plant growth and ensuring that plants can obtain the necessary water supply even in drought and other water-scarce environments. The evaporation suppression sleeve 310 in the water anti-evaporation device 300 is sleeved on the water guide 200, effectively reducing the evaporation of water on the water guide 200. The evaporation suppression sleeve 310 is connected to the water storage container 100, forming a relatively closed space, preventing direct contact between water and dry soil or outside air, thereby reducing the rate of water evaporation and improving the utilization rate of water resources.

[0030] In the aforementioned drought-resistant water supply device for agriculture and forestry, water storage containers 100 of different capacities are selected according to the degree of drought or size of the plants to ensure sufficient water supply. The water-drawing end of the water guide 200 is placed inside the water storage container 100, and the water-transmitting end of the water guide 200 extends outward to the target water supply area of ​​the underground plant roots. The evaporation suppression sleeve 310 of the water anti-evaporation device 300 is fitted onto the water guide 200 to prevent the water guide 200 from directly contacting the drought-stricken soil. This prevents the water in the water guide 200 from being absorbed by the drought-stricken soil before it is delivered to the target water supply area of ​​the plant roots, and also prevents the water on the water guide 200 from evaporating, thereby improving water supply efficiency, reducing water loss caused by evaporation, and greatly improving the utilization efficiency of water resources. It is especially suitable for arid areas or agricultural and forestry planting areas with relatively scarce water resources. Moreover, the stable water supply can meet the needs of plants at different growth stages, promote the development and growth of plant roots, enhance the drought resistance of plants, improve the survival rate and growth quality of plants, and thus improve the yield and quality of agricultural and forestry crops.

[0031] In one specific embodiment, the moisture evaporation prevention device 300 includes a hollow cone 320. The water storage container 100 is connected to the conical portion of the hollow cone 320. A plurality of connection ports 321 are provided on the conical surface of the hollow cone 320. The connection end of the evaporation inhibition sleeve 310 is detachably mounted on the connection port 321, for example, the connection end of the evaporation inhibition sleeve 310 is threadedly connected to the connection port 321. The water delivery end of the water guide 200 extends outward through the connection port 321 to the target water supply area of ​​the underground plant roots.

[0032] The hollow cone 320 has a connection port 321 on its conical surface, and the connection end of the evaporation inhibition sleeve 310 is detachably mounted on the connection port 321. This design simplifies the installation and disassembly of the entire water evaporation prevention device 300. Furthermore, multiple connection ports 321 can be provided on the conical surface of the hollow cone 320, and each connection port 321 can be equipped with one water guide 200 and one evaporation inhibition sleeve 310 to simultaneously supply water to multiple plants, thereby improving water supply efficiency.

[0033] In a preferred embodiment, the water guide 200 includes a strip-shaped absorbent cotton 210 and a plate-shaped extension 220. One end of the strip-shaped absorbent cotton 210 is in contact with the water in the water storage container 100, and the other end of the strip-shaped absorbent cotton 210 is connected to the plate-shaped extension 220. The plate-shaped extension 220 is disposed in the target water supply area of ​​the underground plant roots.

[0034] In this embodiment, the plate-type extension 220 is connected to the strip-shaped absorbent cotton 210 and is positioned in the target water supply area around the underground plant roots. Its larger area can cover a wider range of plant roots. Compared to relying solely on the narrow water supply range of the strip-shaped absorbent cotton 210, the plate-type extension 220 can distribute water more evenly into the surrounding soil, allowing plant roots to absorb water at different locations. Because the plate-type extension 220 increases the water supply area, water can penetrate the surrounding soil more quickly, improving the efficiency of water transfer from the water storage container 100 to the plant roots. In arid environments, this efficient water supply method can replenish water to plants promptly, reducing damage caused by water shortage, enhancing the plant's drought resistance, helping plants maintain normal physiological functions during drought periods, and improving survival rate and growth quality.

[0035] Furthermore, the plate extension 220 includes an absorbent cotton plate 221 and two protective mesh plates 222. The absorbent cotton plate 221 is connected to the water guide 200, and the two protective mesh plates 222 are respectively disposed on the top and bottom of the absorbent cotton plate 221.

[0036] The absorbent board 221 described in this embodiment has a strong water absorption and retention capacity, capable of rapidly absorbing water transferred from the strip absorbent cotton 210 and storing it internally. When plant roots require water, the absorbent board 221 can continuously and stably release water to the surrounding soil, ensuring that plant roots receive sufficient water supply for a long time. Even during droughts, the water stored in the absorbent board 221 can provide a certain buffer for plants, reducing damage caused by temporary water shortage. The two protective mesh panels 222 set on top and below the absorbent board 221 play an important protective role. The protective mesh panels 222 can prevent large particles, stones, etc. in the soil from directly contacting and compressing the absorbent board 221, avoiding damage or blockage, thereby ensuring the normal functioning of its water absorption and transport functions. At the same time, the protective mesh 222 can also block some pests and microorganisms from eroding the absorbent cotton board 221, reduce the damage to the absorbent cotton board 221 caused by biological factors, and extend the service life of the entire board extension 220 and the water guide 200.

[0037] In a preferred embodiment, a water collection device 400 is also included for collecting water.

[0038] The upper part of the water collection device 400 (such as a funnel-shaped water inlet) is located on the ground, and the lower part of the water collection device 400 is connected to the conical surface of the hollow cone 320. The water collection device 400 is used to collect water, and the collected water flows into the water storage container 100 through the hollow cone 320.

[0039] The water collection device 400 enables this agricultural and forestry drought-resistant water supply system to rely not only on external artificial watering or initial water storage. It can collect natural precipitation, such as rainwater, and guide it to the storage container 100, increasing the water supply channels. During periods of abundant rainfall, the water collection device 400 can collect and store large amounts of rainwater, providing a continuous water supply to plants during droughts. This effectively alleviates water shortages during droughts, greatly improving the stability and reliability of the water supply system and ensuring the plant's growth needs under different climatic conditions. By collecting natural precipitation and storing it in the storage container 100, the ineffective loss of rainwater is avoided, and water resources that might otherwise be wasted are reused. This water recycling method is particularly suitable for water-scarce areas, maximizing the use of every drop of water, improving the overall efficiency of water resource utilization, and aligning with the concept of sustainable development.

[0040] In one specific embodiment, the water storage container 100, the water guiding component 200, and the moisture anti-evaporation device 300 are all buried in the underground target water supply area. The water collection device 400 includes a hollow pipe 410, a first water collection component 420, and a second water collection component 430. A portion of the hollow pipe 410 is buried underground. One end of the hollow pipe 410 is connected to the hollow cone 320, and the other end of the hollow pipe 410 is connected to the first water collection component 420. The first water collection component is located on the ground surface and is used to collect surface water. The second water collection component 430 is connected to a portion of the hollow pipe 410 buried underground and is used to absorb moisture from the soil.

[0041] The first water collection component 420, located on the ground, can extensively collect surface water resources, such as surface runoff from rainfall and excess water generated during irrigation. During rainfall, the first water collection component 420 can quickly gather surface water and transport it through the hollow pipe 410 to the water storage container 100, preventing the ineffective loss of surface water, increasing the amount of water collected, and providing more water reserves for plants during drought periods. The second water collection component 430 is connected to a section of the hollow pipe 410 buried underground and can absorb moisture from the soil. The soil stores a certain amount of moisture, especially after rainfall or in areas with high groundwater levels. The second water collection component 430 can absorb this soil moisture and introduce it into the water storage container 100, further expanding the water collection channels. Even in the event of prolonged periods without effective rainfall, it can still obtain a certain amount of moisture from the soil, improving the stability and reliability of the water supply system.

[0042] In addition, a section of the hollow pipe 410 is buried underground. This design reduces water loss due to evaporation during transmission. The underground environment is relatively stable with minimal temperature fluctuations and poor air circulation, effectively minimizing water loss caused by evaporation. Furthermore, the underground location of the hollow pipe 410 prevents damage from external surface forces, such as human trampling or vehicle traffic, ensuring smooth water transmission.

[0043] In one specific embodiment, the first water collection component 420 includes a water storage tank 421, the bottom of which is connected to the hollow tube 410. A water collection plate 422 is provided on the water storage tank 421, and a guide hole 423 is provided on the water collection plate 422. The water collection plate 422 also has a guide slope to collect water from the edge of the water collection plate 422 towards the center.

[0044] The guide holes 423 and the guiding slope on the water collection plate 422 play a crucial role in guiding the water flow. The guiding slope allows water falling on the edge of the water collection plate 422 to naturally gather towards the center, while the guide holes 423 further guide this water accurately into the water storage tank 421. For example, during rainfall, the water on the water collection plate 422 will flow rapidly towards the center along the guiding slope and quickly flow into the water storage tank 421 through the guide holes 423, preventing water from flowing around on the water collection plate 422 and failing to be effectively collected.

[0045] The water storage tank 421 is also provided with a water inlet hole on its side wall for quickly collecting rainwater during windy and rainy weather.

[0046] In one specific embodiment, the second water collection component 430 includes a plurality of water storage rods 431. The water storage rods 431 are connected to a portion of the hollow pipe 410 buried underground, and the water storage rods 431 are inclined upwards, forming an inclination angle (30-50°) with the portion of the hollow pipe 410. The water storage rods 431 are provided with absorbent cotton strips, and a plurality of absorbent strip holes 432 are opened on the side wall of the water storage rods 431. The water storage rods 431 are inclined upwards to facilitate the flow of absorbed water into the hollow pipe 410.

[0047] The absorbent cotton strips installed inside the water storage rod 431 have strong water absorption. Through multiple absorbent strip holes 432 opened on the side wall of the water storage rod 431, the absorbent cotton strips can absorb water from the soil like a sponge and store it. The absorbent cotton strips can stably retain the water inside the water storage rod 431, and through the connection with the hollow tube 410, the water is continuously transported to the water storage container 100.

[0048] Furthermore, multiple hollow cones 320 are configured to simultaneously supply water to multiple underground target areas. The multiple hollow cones 320 are connected in series, and the conical surface of any hollow cone 320 is connected to the evaporation suppression sleeve 310. The conical part of the hollow cone 320 at the bottom is connected to the water storage container 100.

[0049] In a preferred embodiment, a filtration device is provided inside the hollow tube 410 for filtering impurities in the collected water. The filtration device may include activated carbon and a filter screen.

[0050] In a preferred embodiment, the evaporation suppression sleeve 310 is a flexible tube.

[0051] Because flexible hoses can fit snugly against the surface of the pipe or component being protected, they form a more effective isolation layer, reducing the contact area between air and water, thus more effectively suppressing moisture evaporation. Compared to rigid sleeves, flexible hoses can better adapt to minor deformations and irregular shapes of the protected object, ensuring good evaporation suppression throughout the entire protected area.

[0052] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model.
