Description

Technical Field

[0001] This invention belongs to the field of plant protection technology, and in particular relates to a grassland ecological restoration vegetation protection device. Background Technology

[0002] Plant protection, a core issue in ecology, is a crucial cornerstone supporting human sustainable development strategies. The widespread lack of environmental awareness in contemporary society has led to severe damage to natural vegetation and continuous degradation of land ecological functions. Human activities causing the deterioration of vegetation habitats have accelerated desertification, exhibiting multi-dimensional harm: the destruction of sandy or compacted soil structures not only results in organic matter loss but also creates a vicious cycle due to a sharp decrease in aeration, rendering the land unusable for basic planting. In ecological restoration practices, strong winds become a core obstacle to seedling survival—the mechanical stress they generate easily leads to stem breakage, while simultaneously exacerbating topsoil erosion, causing root exposure and water loss, ultimately significantly reducing the success rate of vegetation restoration. This chain reaction highlights the strategic importance of windbreak and sand-fixing technologies in the management of degraded land.

[0003] Therefore, it is necessary to propose a grassland ecological restoration and vegetation protection device to solve the above problems. Summary of the Invention

A windproof shelter is provided around the ecological section. The ecological section includes multiple ecological frames laid on the water replenishment section, with adjacent ecological frames detachably connected by connectors.

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.

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] The technical terms used in the embodiments are explained below:

[0028] Solar panels are the core power source for grassland ecological restoration and vegetation protection devices. Their design is closely centered around three main objectives: efficient power supply, environmental adaptability, and sustainable operation. Their specific components are as follows:

[0029] Solar photovoltaic panels:

[0031] Structure: Flexible and lightweight design (3mm thickness, 2kg / ㎡), adaptable to grassland terrain undulations, wind pressure resistance ≥2000Pa.

[0032] Layout: The tilt angle is adjustable (30°-45°) to maximize the reception of solar radiation (estimated annual power generation: 5kWh / ㎡·year).

[0033] Storage battery:

[0034] Type: Lithium iron phosphate battery, cycle life ≥2000 cycles, depth of discharge (DOD) 80%.

[0035] Capacity: Designed according to the device's power consumption, the typical configuration is 48V / 100Ah, which can meet the power supply requirements for 3 consecutive days without sunlight.

[0036] Controller:

[0037] Features: Maximum power point tracking (MPPT), charging efficiency ≥98%; integrated overvoltage / undervoltage protection and temperature compensation.

[0038] Communication: Supports RS485 / Modbus protocol for real-time data interaction with the sensing control module.

[0039] Support system: made of aluminum alloy, with anti-corrosion treatment (no rust after 96 hours of salt spray test), height adjustable (0.5-1m) to avoid snow accumulation.

[0040] Cable system: Photovoltaic special cable (PV1-F), temperature range -40℃ to 120℃, flame retardant rating V-0.

[0041] Daily power generation: In grassland areas (average annual sunshine hours of 3000 hours), the daily power generation of a single photovoltaic panel (1㎡) is ≥1.5kWh, which meets the needs of the lifting unit (daily power consumption of 0.5kWh), the induction module (daily power consumption of 0.1kWh) and the drip irrigation system (daily power consumption of 0.3kWh).

[0042] Energy storage redundancy: The battery capacity is designed to be 3 times the daily power demand to ensure normal operation during continuous rainy days (≥3 days).

[0043] Temperature range: The photovoltaic panel operates at a temperature of -40℃ to 85℃, and the battery temperature control system (forced air cooling) ensures stable operation in an environment of -20℃ to 50℃.

[0044] Protection rating: The entire component reaches IP65, is dustproof and waterproof, and is suitable for grassland sandstorms and rainy environments.

[0045] Initial investment: The cost of photovoltaic systems accounts for 15%-20% of the total cost of the installation, which is 30% higher than the initial investment of diesel generator solutions, but the operation and maintenance costs are reduced by 90%.

[0046] Carbon emission reduction: Each unit reduces carbon dioxide emissions by 1.2 tons per year (calculated based on photovoltaic power generation replacing diesel power generation), which meets the carbon neutrality target.

[0047] Lifting Unit Drive: Solar panels provide power to the telescopic component (electric push rod), enabling rapid lifting and lowering of the windproof unit (response time <30 seconds).

[0048] Power supply for sensing modules: Low-power devices such as wind speed sensors and controllers are directly powered by the photovoltaic system, eliminating the need for an external power source.

[0049] Energy consumption optimization: The controller dynamically adjusts the power supply strategy according to the light intensity, giving priority to the operation of critical equipment (such as wind speed sensors).

[0050] Data interaction: Data such as power generation and battery status are transmitted to the remote monitoring platform via RS485 bus to enable remote operation and maintenance.

[0051] Material recycling: The photovoltaic panel bracket is made of recyclable aluminum alloy, and the batteries are recycled by the manufacturer after they reach the scrapping standard (recycling rate ≥95%).

[0052] Land use: The photovoltaic panel array is designed with a spacing of 2m to allow herbaceous plants to grow naturally and avoid shading from affecting vegetation restoration.

[0053] Solar modules, through the integration of photovoltaic power generation, energy storage control, and intelligent power supply technologies, provide clean, reliable, and continuous power support for grassland ecological restoration devices. Their technological advantages are reflected in multiple dimensions, including power supply efficiency, environmental adaptability, economic efficiency, and ecological synergy, making them the core guarantee for the device to achieve unattended, long-term operation.

[0054] The wind speed sensor is the core component of the sensing and control module. Mounted on the fixed part (base), it is used to monitor wind speed in real time and control the raising and lowering of the windproof section. Its core functions include:

[0055] Wind speed monitoring: Detects changes in wind speed through built-in sensor elements (such as ultrasonic or mechanical wind catchers).

[0056] Data transmission: The wind speed data is transmitted to the controller, triggering the lifting and lowering logic of the windproof unit.

[0057] Environmental adaptability: Adaptable to harsh grassland environments (such as sandstorms and low temperatures).

[0058] In the patented device, the installation location of the wind speed sensor must meet the following requirements:

[0059] Fixed component integration: Installed on the base, the height can be adjusted (0.5~1m) via brackets to avoid snow accumulation.

[0060] Wind adaptability: It adopts a three-cup or ultrasonic design, providing 360° all-round monitoring with no angle limitations.

[0061] Wind-resistant design: The support frame is made of aluminum alloy with a wind resistance of ≥75m / s, ensuring that it will not be damaged under extreme wind speeds.

[0062] The interaction process between the wind speed sensor and the control system is as follows:

[0063] Data acquisition: The sensor converts the wind speed into a voltage signal (0-5V) and transmits it to the controller.

[0064] Threshold judgment: The controller presets a wind speed threshold (e.g., 15m / s). When the wind speed exceeds the threshold, the windproof part is triggered to rise or fall.

[0065] Lifting control: Commands are sent to the lifting unit (electric push rod) via RS485 bus to achieve rapid lifting and lowering of the windproof unit (response time <30 seconds).

[0066] Status feedback: After the windproof part is raised or lowered to the correct position, the sensor sends a feedback signal to the controller, forming a closed-loop control.

[0067] Dustproof and waterproof: It has an IP67 protection rating and a sealed design to prevent sand and rainwater from entering.

[0068] Electromagnetic interference resistance: Built-in EMI filter circuit to avoid interference from lightning strikes or nearby equipment.

[0069] Low temperature adaptability: Built-in heating module (such as PTC heating element) ensures normal start-up in an environment of -40℃.

[0070] Long lifespan design: Ultrasonic sensors have no mechanical wear and a lifespan of >10 years; mechanical sensors use stainless steel bearings and have a lifespan of >5 years.

[0071] In grassland ecological restoration devices, wind speed sensors are typically used in the following ways:

[0072] Strong wind protection: When the wind speed is >15m / s, the windproof part is raised to the highest position (30cm) to reduce the near-ground wind speed by 50%.

[0073] Breeze optimization: When the wind speed is <5m / s, the windproof part is lowered to avoid blocking sunlight and promote seedling growth.

[0074] Data recording: Wind speed data is stored via SD card or remote platform to provide a basis for evaluating the effectiveness of ecological restoration.

[0075] Accuracy and reliability: The ultrasonic sensor has an accuracy of ±0.3m / s and a false alarm rate of <1%, ensuring the precise operation of the windproof unit.

[0076] Low power consumption: Static power consumption <1W, the solar power system can meet the needs of 3 consecutive days without sunlight.

[0077] Maintenance cost: With no mechanical wear design, the annual maintenance cost is less than 30% of that of traditional mechanical sensors.

[0078] Wind speed sensors, through the integration of high-precision monitoring, rapid response, and intelligent control technologies, provide reliable wind speed data support for grassland ecological restoration devices. Their technological advantages are reflected in multiple dimensions, including measurement accuracy, environmental adaptability, control logic, and economic efficiency, making them a core component for achieving dynamic protection and improving seedling survival rates.

[0079] Reference Figures 1 to 6 As shown, the present invention provides a grassland ecological restoration vegetation protection device, including a support part, on which a water replenishment part and an ecological part are arranged in sequence. The ecological part is surrounded by a windproof shelter. The ecological part includes multiple ecological frames 7, which are laid on the water replenishment part. Adjacent ecological frames 7 are detachably connected by connectors. The interior of the ecological frame 7 is laid with a water-absorbing layer, a substrate layer 14 and a substrate protective layer from bottom to top. The windproof shelter includes a fixing part, a lifting part, a windproof part, a sensing control module and a solar panel. The sensing control module and the lifting part are electrically connected to the solar panel. The sensing control module is used to monitor the wind speed and control the operation of the lifting part. The lifting part is used to adjust the height of the windproof part.

[0080] In this embodiment, the support part is the first grid plate 2 laid on the soil base layer. The first grid plate 2 and the ecological frame 7 are both molded from coconut fiber, which is biodegradable and does not pollute the environment. The windbreak shelter of the present invention can be reused after vegetation restoration and will not have an impact on the ecology. The solar energy component consists of solar photovoltaic panels and batteries, which can continuously power the windbreak shelter. The sensing module integrates a wind speed sensor 16 and a controller, which are installed on the fixing part.

[0081] The sensor control module monitors wind speed in real time and automatically adjusts the height of the windproof section through the lifting unit, enabling the windproof plate to rise quickly in strong winds and fall in weak winds to avoid blocking sunlight and thus prevent seedling stem damage. The water absorption layer collects and stores water from the water supply section, providing sufficient water for seedling growth. The modular ecological frame 7 facilitates on-site construction and improves construction efficiency. The substrate protection layer stabilizes the substrate and prevents seedling roots from being exposed and losing water.

[0082] Furthermore, the fixing part includes a base 3, which is fixed to the soil by a ground plug 1. A groove is provided on the base 3, and the windproof part is slidably disposed in the groove.

[0083] By inserting the ground stake 1 into the soil, the base 3 is fixed to prevent it from being blown over by strong winds. Multiple bases 3 are installed according to the repair area and enclosed to form a frame, which facilitates the subsequent laying of the ecological section.

[0084] Furthermore, the lifting unit includes multiple telescopic components 8 fixed in the groove, the output ends of the multiple telescopic components 8 are fixedly connected to the bottom end of the windproof unit, and the multiple telescopic components 8 are all electrically connected to the sensing control module.

[0085] In this embodiment, the telescopic component 8 is an electric actuator.

[0086] When the wind speed detected by the wind speed sensor 16 in the sensing module exceeds the preset threshold, the information is transmitted to the controller. The controller then controls multiple telescopic components 8 to extend synchronously, raising the windproof section to protect the seedlings. When the wind speed returns to a light or windless environment, the controller controls multiple telescopic components 8 to retract synchronously, pulling the windproof section back into the groove. It should be noted that multiple wind speed sensors 16 are provided to detect wind from different directions.

[0087] Furthermore, the windproof part includes a frame 5 slidably connected in the groove, a windproof plate 15 connected inside the frame 5, and multiple air vents opened on the windproof plate 15.

[0088] By incorporating vents, the windbreak 15 can be less overloaded, protecting the seedlings from being blown off.

[0089] Furthermore, the water replenishment part includes a water-stop membrane laid on the top surface of the support part, and multiple drip irrigation tapes 17 are laid on the water-stop membrane at equal intervals. Multiple pads 6 are set on the drip irrigation tapes 17, and a second grid plate 4 is set on the multiple pads 6. A water-retaining agent 13 is filled between the second grid plate 4 and the water-stop membrane. The drip irrigation tapes 17 are connected to the water supply device.

[0090] In this embodiment, the water supply device includes a water collection tank and a water pump. The water pump is electrically connected to the solar panel. The water collection tank collects rainwater, and the water pump supplies water to multiple drip irrigation tapes 17. Each drip irrigation tape 17 is equipped with an individual valve. The pad 6 is made of recycled plastic or rubber, with a load-bearing capacity ≥200kg / m. 2 Ensure the distance between the drip irrigation tape and the water-retaining agent layer.

[0091] The water-stopping membrane is made of biodegradable material, which can block water seepage and reduce deep leakage loss. The drip irrigation tape 17 replenishes water for the water-retaining agent 13. The water-retaining agent 13 absorbs water and expands to store water, and together with the water-retaining agent 13 at the bottom of the ecological frame 7, it forms a water storage system that can provide sufficient water for the seedling roots.

[0092] Furthermore, in order to achieve modular and rapid assembly, the connector is an elastic clamp 12, the ecological frame 7 is a rectangular frame, and elongated holes 10 are opened on all four sides of the ecological frame 7. The elastic clamp 12 is engaged with the elongated holes 10 to achieve stable fixation between the ecological frames 7. When the seedlings grow, the elastic clamp 12 can be removed and recycled.

[0093] Furthermore, semi-circular notches 11 are provided around the four sides of the ecological frame 7. The semi-circular notches 11 on two adjacent ecological frames 7 form a circular cavity. Ecological nails 18 are inserted into the circular cavity, and the ecological frame 7 is fixed to the water supply part by the ecological nails 18.

[0094] The ecological frame 7 passes through the circular cavity and is inserted into the mesh of the second grid plate 4 to achieve stable fixation of the ecological frame 7.

[0095] Furthermore, the water-absorbing layer is formed by laying water-retaining agent 13.

[0096] The water-retaining agent 13 at the bottom of the ecological frame 7 and the water-retaining agent 13 filled between the second grid plate 4 and the water-stop membrane form a water storage system. In order to accelerate the capillary action of water, multiple hemp ropes are set at the bottom of the ecological frame 7, and the ends of the hemp ropes are buried in the water-retaining agent 13 at the bottom of the second grid plate 4.

[0097] Furthermore, the substrate layer 14 is formed by mixing slow-release fertilizer with soil.

[0098] In this embodiment, the slow-release fertilizer used is cooked cow manure.

[0099] Furthermore, the matrix protective layer is composed of a honeycomb grid 9.

[0100] The honeycomb mesh 9 is made of coconut fiber.

[0101] The construction method of the grassland ecological restoration vegetation protection device provided by the present invention is as follows: the base 3 is fixed according to the area where the vegetation needs to be restored to form a frame. The pit foundation is dug in the area within the frame. The first grid plate 2 is laid in the pit foundation. A water-stop membrane is laid on the first grid plate 2. A drip irrigation tape 17 is laid on the water-stop membrane and connected to the water supply device. A pad block 6 is placed on the drip irrigation tape 17 for support. The second grid plate 4 is placed on the pad block 6. The second grid plate 4 and the first grid plate 2 are filled with water-retaining agent 13. Then, the ecological frame 7 is spliced. Hemp rope is placed at the bottom of each ecological frame 7 and stuffed into the mesh of the second grid plate 4. Then, water-retaining agent 13, mature cow manure, grass seeds and soil are poured into the ecological frame 7 in sequence. A honeycomb grid 9 is laid on the top of the soil and placed into the ecological frame 7. The wind speed sensor 16 and solar panel are installed.
