Description

An agricultural water storage and plant protection device Technical Field

[0001] This invention relates to the technical field of agricultural water storage and plant protection devices, specifically an agricultural water storage and plant protection device. Background Technology

[0002] Existing technologies have significant practical value in agricultural irrigation and crop protection, playing a fundamental role in ensuring crop growth, maintaining soil moisture, preventing competition from weeds, and supporting plant morphology. Traditional methods such as manual irrigation and physical protective frames can meet the needs of crop growth to a certain extent and are still widely used, especially in situations with limited resources or small-scale planting, demonstrating their practicality and adaptability in actual production.

[0003] However, existing technologies still have significant drawbacks. For example, reliance on manual judgment and operation leads to untimely irrigation, high labor intensity, and harsh working environments; the use of herbicides can easily cause phytotoxicity to cash crops; protective frames inserted directly into the soil have poor stability and are easily collapsed due to weather conditions; existing irrigation or protection devices are mostly integrated or fixed structures, making it impossible to flexibly adjust their layout according to the scale of crop planting, and installation and expansion are inconvenient; water resource utilization efficiency is low, and there is a lack of intelligent regulation and recycling mechanisms. Especially when dealing with complex and changeable natural environments, existing devices lack adaptive capabilities and cannot achieve intelligent adjustment based on conditions such as water level and weather, limiting their application effectiveness in large-scale, precision agriculture. Summary of the Invention

[0004] (I) Technical problems to be solved In view of the shortcomings of the existing technology, the present invention provides an agricultural water storage and protection device, which has the functions of automatic rainwater collection and storage, physical blocking of weed roots, stable and assemblable protective frame and self-adaptive adjustment in water tank. It solves the problems of traditional agricultural irrigation relying on manual labor, high labor intensity, low water resource utilization efficiency, easy herbicide damage to crops, poor stability of protective frame and inability to intelligently respond to environmental changes.

[0005] (II) Technical Solution To achieve the above-mentioned objectives of automatic rainwater collection and storage, physical isolation of weed roots, stable and assemblable protective frame, and adaptive adjustment within the water tank, the present invention provides the following technical solution: An agricultural water storage and plant protection device, comprising: at least two interlocking bases, the lower part of each base being disposed within the ground, and the bases being interlocked to form an enclosing structure surrounding the plant planting area; a water storage and irrigation unit, comprising a hollow cavity disposed within each base, a rainwater collection port and an irrigation outlet communicating with the hollow cavity, and a water level adjustment structure for supplying water from the hollow cavity to the plant planting area; wherein, a guide cover is provided above the rainwater collection port, the guide cover having a guide surface inclined downward from the outside to the inside, and rainwater is introduced into the hollow cavity through the guide cover.

[0006] Preferably, it also includes a protective frame, which is disposed on the upper part of the base and distributed in an array around the plant planting area.

[0007] Preferably, each of the bases has a splicing structure on its side, the splicing structure including a protruding tenon and a recessed groove, and adjacent bases are spliced ​​and fixed by the cooperation of the tenon and the groove.

[0008] Preferably, the water level regulating structure includes a micro water pump, an upper pipe, and a solar panel. The micro water pump is located at the bottom of the hollow cavity, and the upper pipe connects the micro water pump to the irrigation outlet. The solar panel is located on the base and is electrically connected to the micro water pump.

[0009] Preferably, it also includes a monitoring and control unit, which includes a soil environment monitor mounted on the base. The monitoring and control unit is signal-connected to the micro water pump and is used to control the start and stop of the micro water pump according to the soil moisture signal.

[0010] Preferably, the water level regulating structure includes a lower channel and a track. The lower channel is disposed at the bottom of the hollow cavity, and the track is disposed on the inner side wall surface of the hollow cavity. The lower channel can move up and down along the track. The side wall of the lower channel is provided with a connecting interface, which is tightly fitted to the inner wall of the hollow cavity. When the lower channel moves to the highest point along the track, the connecting interface aligns with the water outlet, and the water inside the lower channel flows into the plant planting area from the connecting interface through the water outlet.

[0011] Preferably, the lower channel moves on the track by a pull rope that extends from the inside of the hollow cavity to the outside and is fixed to the outside of the base.

[0012] Preferably, the water level regulating structure includes an air bladder, an air supply pipe, and a heating box; the air bladder is located at the bottom of the hollow cavity; the heating box is made of a dark-colored material and is fixedly installed on the outer surface of the base, directly exposed to external sunlight; the heating box is connected to the interior of the air bladder through the air supply pipe, forming a closed air passage system; when sunlight causes the air inside the heating box to expand due to heat, gas enters the air bladder through the air supply pipe, the volume of the air bladder increases, and the water level in the hollow cavity rises.

[0013] Preferably, the heating box is fixedly mounted on the side wall of the base, and the base has an air duct channel at a position corresponding to the heating box. The air supply pipe passes through the inside of the air duct channel, and the two ends of the air supply pipe are respectively connected to the airbag and the heating box. The outer wall of the air supply pipe and the inner wall of the air duct channel are sealed by filling with colloid.

[0014] Preferably, the rainwater collection port includes a filter screen and a flow guiding film, the flow guiding film guiding rainwater on its upper surface into the hollow cavity; the filter screen has filter holes on its surface; the filter screen is vertically arranged between the flow guiding film and the hollow cavity, and rainwater entering the hollow cavity from the upper surface of the flow guiding film passes through the filter holes.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides an agricultural water storage and plant protection device with the following beneficial effects: 1. The agricultural water storage and plant protection device adopts a modular base design that can be spliced, which realizes flexible assembly and expansion according to the planting area, significantly improving the installation adaptability and ease of use; at the same time, the inclined guide cover plate set above the rainwater collection port effectively expands the water collection area and guides rainwater into the water storage cavity, while also reducing water evaporation and initially intercepting debris, thereby enhancing the overall practicality, water-saving and environmental adaptability of the device.

[0016] 2. This agricultural water storage and plant protection device significantly enhances the overall structural stability of the protective frame by securely mounting it onto a base, with the base partially buried in the soil. This effectively overcomes the shortcomings of traditional protective frames that are easily loosened and collapsed when directly inserted into the soil. Simultaneously, the device innovatively incorporates a hollow cavity structure within the base, which automatically collects and stores natural rainwater, achieving highly efficient water resource utilization. This not only significantly reduces reliance on external irrigation water and lowers the labor intensity of manual irrigation but also provides timely and precise water replenishment when crops require it, improving the intelligence and reliability of irrigation management.

[0017] 3. This agricultural water storage and plant protection device effectively increases the rainwater receiving area and improves the collection efficiency of natural precipitation by adding a filter screen and a flow-guiding film to the rainwater collection inlet. The flow-guiding film can extend and gently suspend above the crops in the central planting area. It can be flexibly adjusted and replaced according to the growth size of different crops, achieving wide adaptability to plants of different heights and canopies. It can also create a local moisturizing microenvironment around the plants, reducing soil moisture evaporation. It has both efficient water collection and moisture retention functions, and is more flexible and ecologically beneficial than traditional fixed water collection structures.

[0018] 4. This agricultural water storage and planting protection device, through three different structural embodiments, achieves automatic and adaptive water supply when the water level in the cavity drops. It effectively overcomes the shortcomings of traditional irrigation methods, which rely on manual judgment, are cumbersome to operate, and cannot accurately respond to environmental changes. The first embodiment uses a water pump and upper pipe for connection, utilizing solar panel power to directly transport rainwater located in the lower half of the hollow cavity to the planting area through the outlet, based on the specific soil conditions. This significantly improves upon the water resource waste problem of traditional continuous or timed irrigation methods. The second embodiment uses a combination of a rope and a track. Depending on the specific usage, the rope can be pulled by an external engine or manually. During the slow ascent, the outlet and the connecting port gradually overlap, and rainwater located at the bottom of the hollow cavity, i.e., inside the lower channel, enters the planting area from the outlet, ensuring that the water level inside the hollow cavity rises during rain. When the temperature is high, water will not be continuously supplied to the plant planting area, fundamentally avoiding the problem of overwatering caused by ignoring natural rainfall in traditional irrigation. Only on sunny days, the rope is pulled and fixed, and rainwater collected in the lower channel is introduced into the plant planting area. The third embodiment utilizes the principle of thermal expansion and contraction of gas. An air bladder is installed at the bottom of the hollow cavity and connected to the heating box through an air supply pipe. When the weather is sunny and the temperature is high, the black outer surface causes the heating box to absorb heat, heating the internal gas. The internal gas expands due to heat and enters the air bladder through the air supply pipe. After the air bladder expands, it raises the water level, and water flows into the plant planting area from the outlet. When night falls and the temperature drops, the air bladder returns to its initial size, the gas returns to the heating box, and the water level drops. Without any external power or manual intervention, it can achieve responsive water supply synchronized with changes in ambient temperature. Compared with traditional electrified automatic irrigation systems, it has higher reliability and environmental adaptability. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please refer to Figures 1-2 and 7. This invention provides an agricultural water storage and plant protection device, the core design of which aims to solve many drawbacks of traditional irrigation and protection technologies. The device mainly includes at least two interlocking bases 1, a water storage and irrigation unit 2, and an optional protective frame 11. Unlike traditional fixed, integrated agricultural facilities, this device adopts a unique modular splicing design: each base 1 has a splicing structure on its side, specifically including protruding tenons 13 and recessed grooves 14. Through the interlocking of the tenons 13 and grooves 14, adjacent bases 1 can be stably connected, thereby flexibly combining to form an enclosing structure around the plant planting area 4. This design gives the device extremely high layout flexibility and scalability. Users can freely increase or decrease the number of bases according to the crop planting area and shape, overcoming the defects of fixed device size and difficulty in adapting to different planting scales in existing technologies. The lower part of each base 1 needs to be buried in the ground, which provides a stable foundation for the entire device. A protective frame 11 can be installed on the upper part of the base 1, and the protective frame 11 is distributed in an array around the plant planting area 4. The key improvement is that the protective frame 11 is not directly inserted into the unstable soil as in the traditional way, but is firmly installed on the base 1 buried deep underground, thereby transferring the force to the more stable bottom layer. This fundamentally overcomes the shortcomings of traditional protective frames that are easy to loosen and collapse, and significantly enhances the wind resistance and durability of the overall structure.

[0023] Please refer to Figures 1 and 2. The water storage and irrigation unit 2 is the core for achieving efficient water resource utilization and automatic irrigation. It is located inside each base 1 and includes a hollow cavity 21 for storing rainwater, a rainwater collection port 22 connected to the hollow cavity 21, an irrigation outlet 23, and a water level adjustment structure 3 for automatic or semi-automatic water supply. Regarding rainwater collection, this invention features dual optimizations, significantly different from simple water collection troughs. First, a guide cover 12 with a specific structure is added above the rainwater collection port 22. This guide cover 12 is designed as a downward-sloping guide surface from the outside in. The purpose and function of this design are: on the one hand, to effectively increase the rainwater receiving area and guide rainwater to the collection port more efficiently; on the other hand, its inclined structure can physically block the opening, directly reducing direct sunlight evaporation of water in the storage cavity, while also initially intercepting fallen leaves, large particles, etc., thus possessing multiple advantages such as improving water collection efficiency, maintaining water quality, and reducing ineffective water loss. Secondly, below the guide cover 12, the rainwater collection port 22 further includes a filter screen 221 and a guide film 222. The filter screen 221 is vertically arranged with filter holes 2211 on its surface for secondary filtration of the incoming rainwater, preventing silt blockage. The guide film 222 can be flexibly extended to partially cover the plant planting area 4. The special feature of this design is that it not only assists in guiding the flow but also flexibly adjusts the hanging range according to the plant height of different crops. While creating a local moisturizing microenvironment around the plants and reducing soil moisture evaporation, it achieves wide adaptability to a variety of crops. Compared with traditional fixed and rigid water collection structures, it demonstrates significant flexibility and ecological benefits. The collected rainwater is stored in the hollow cavity 21, realizing the effective accumulation and recycling of natural precipitation and reducing dependence on artificial irrigation and external water sources.

[0024] Referring to Figure 3, another major innovation of this invention lies in providing various embodiments of the adaptive water level regulation structure 3 to solve the problems of traditional irrigation relying on manual labor, slow response, and lack of intelligence. The first embodiment employs an electromechanical automation scheme: the water level regulation structure 3 includes a micro-pump 31, an upper pipe 32, and a solar panel 5 as a power source. The micro-pump 31 is installed at the bottom of the hollow cavity 21 and connected to the irrigation outlet 23 located at the top of the cavity via the upper pipe 32. The solar panel 5 converts light energy into electrical energy, providing clean energy for the micro-pump 31. More intelligently, this embodiment can also integrate a monitoring and control unit 6, which includes a soil environment monitor capable of real-time monitoring of soil moisture in the planting area 4. When soil drought is detected, the control unit automatically starts the micro-pump 31, precisely pumping rainwater from the bottom of the cavity to the crop roots; it automatically stops when the moisture level reaches the target. This precise irrigation based on actual needs completely avoids the water waste caused by traditional timed or flood irrigation methods, achieving intelligent and reliable irrigation management.

[0025] Referring to Figure 4, the second embodiment provides a mechanical semi-automatic solution, particularly suitable for use in scenarios where electricity is inconvenient or manual intervention is required. The water level regulating structure 3 of this embodiment includes a lower channel 33 located at the bottom of the cavity and a track 34 located on the side wall of the cavity. The lower channel 33 can move up and down along the track 34, and its side wall has a connecting interface 331. During operation, it is manually or mechanically lifted by a pull rope 35 connected to the lower channel 33 and extending to the outside of the base 1. When lifted to the highest point, the connecting interface 331 of the lower channel 33 is precisely aligned with the fixed irrigation outlet 23, at which point the water stored in the channel can be discharged for irrigation. The outstanding advantage of this design lies in its "on-demand water dispensing" active control logic: users can store water in rainy weather and supply water by pulling the pull rope 35 on sunny days when irrigation is needed, thus fundamentally avoiding the problem of over-irrigation caused by continuous automatic water supply during rainy days or when the soil is wet.

[0026] Please refer to Figures 5-6. The third embodiment demonstrates a completely passive, environmentally adaptive thermal drive scheme, exhibiting extremely high reliability and environmental friendliness. The water level regulating structure 3 includes an air bladder 36 located at the bottom of the hollow cavity 21, a heating box 38 made of dark material, and an air supply pipe 37 connecting the two, forming a closed air circuit system. The heating box 38 is fixed to the outer wall of the base 1 and directly exposed to sunlight. Its working principle is based on the physical principle of gas thermal expansion and contraction: during the day, the dark surface of the heating box 38 absorbs solar radiation and heats up, causing the internal air to expand and enter the air bladder 36 through the air supply pipe 37, resulting in an increase in the volume of the air bladder, thereby raising the water level throughout the cavity until water overflows from the irrigation outlet 23, achieving automatic irrigation; at night or on cloudy days when the temperature drops, the gas contracts, the air bladder shrinks, the water level drops, and irrigation stops. The entire process requires no external electricity or manual intervention, achieving a completely synchronous responsive water supply with changes in sunlight and temperature. Compared to electrified automation systems that rely on sensors and circuits, this solution has a simpler structure, lower cost, stronger environmental adaptability, and requires almost no maintenance, giving it a unique advantage in reliability.

[0027] In summary, this invention integrates multiple functions, including rainwater collection, storage, intelligent irrigation, physical protection, and weed isolation, through a modular splicing base, a high-efficiency water collection system with inclined guide covers and membranes, a stable protective frame combined with a deeply buried base, and three distinctive adaptive water supply schemes. It not only significantly reduces labor intensity and reliance on chemical herbicides but also greatly improves water resource utilization efficiency and the device's environmental adaptability, providing an innovative and practical comprehensive solution for modern, precision agriculture.
