[0002] Plant protection, as a core issue in the field of ecology, is a key cornerstone supporting humanity's sustainable development strategy. A widespread lack of environmental awareness in contemporary society has led to severe damage to natural vegetation and the continuous degradation of land ecological functions. The deterioration of the vegetation living environment caused by human activities has accelerated the process of land desertification, and its hazards are multi-dimensional: the destruction of soil structure due to sandification or compaction not only causes the loss of organic matter, but also forms a vicious cycle due to a sudden drop in air permeability, causing the land to lose its basic planting function. In ecological restoration practice, strong winds have become a core obstacle to seedling survival. The mechanical stress they generate can easily cause stem breakage, while also exacerbating topsoil erosion, exposing roots and losing water, ultimately significantly reducing the success rate of vegetation reconstruction.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

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

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

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

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

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

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

[0041] Daily power generation: In grassland areas (average annual sunshine hours of 3,000 hours), a single photovoltaic panel (1 m2) can generate ≥1.5 kWh of electricity per day, meeting the needs of the lifting unit (daily power consumption of 0.5 kWh), the induction module (daily power consumption of 0.1 kWh) and the drip irrigation system (daily power consumption of 0.3 kWh).

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

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

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

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

[0046] Carbon emission reduction: Each device reduces carbon dioxide emissions by 1.2 tons per year (calculated based on photovoltaic power generation replacing diesel power generation), which is in line with the carbon neutrality goal.

[0047] Lifting unit drive: Solar panels provide power for the telescopic parts (electric push rods), enabling the windbreak to rise and fall quickly (response time <30 seconds).

[0048] Power supply for sensing modules: Wind speed sensors, controllers and other low-power devices are directly powered by the photovoltaic system without the need for an external power supply.

[0049] Energy consumption optimization: The controller dynamically adjusts the power supply strategy according to the light intensity, giving priority to the operation of key 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 the RS485 bus to achieve remote operation and maintenance.

[0051] Material recycling: The photovoltaic panel bracket is made of recyclable aluminum alloy, and the battery will be recycled by the manufacturer after reaching the scrap standard (recycling rate ≥95%).

[0052] Land use: The photovoltaic panel array spacing is designed to be 2m, allowing herbaceous plants to grow naturally and avoiding shading that affects vegetation restoration.

[0053] Solar panels, through the integrated technology of photovoltaic power generation, energy storage control, and intelligent power supply, provide clean, reliable, and continuous power support for grassland ecological restoration equipment. Their technological advantages are reflected in power supply efficiency, environmental adaptability, economic efficiency, and ecological synergy, and are the core guarantee for the unmanned and long-term operation of the equipment.

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

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

[0056] Data transmission: The wind speed data is transmitted to the controller to trigger the wind shield lifting logic.

[0057] Environmental adaptability: Adaptable to the harsh grassland environment (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 part integration: Installed on the base, the height is adjusted (0.5~1m) through the bracket to avoid being covered by snow.

[0060] Wind direction adaptability: adopts three-cup or ultrasonic design, 360° all-round monitoring, no angle restriction.

[0061] Wind-resistant design: The bracket is made of aluminum alloy with a wind resistance of ≥75m / s, ensuring it will not be damaged in 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 wind speed into a voltage signal (0-5V) and transmits it to the controller.

[0064] Threshold judgment: The controller presets a wind speed threshold (such as 15m / s), and when the threshold is exceeded, the wind shield will be raised or lowered.

[0065] Lifting control: Send instructions to the lifting part (electric push rod) through the RS485 bus to achieve rapid lifting of the windproof part (response time <30 seconds).

[0066] Status feedback: After the windproof part is raised or lowered into place, the sensor feeds back the signal to the controller to form a closed-loop control.

[0067] Dustproof and waterproof: With IP67 protection level, the sealed design prevents the intrusion of dust and rain.

[0068] Anti-electromagnetic interference: Built-in EMI filter circuit to avoid interference from grassland lightning or nearby equipment.

[0069] Low temperature adaptability: built-in heating module (such as PTC heater) ensures normal startup in -40℃ environment.

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

[0071] In grassland ecological restoration equipment, typical applications of wind speed sensors are as follows:

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

[0073] Breeze optimization: When the wind speed is less than 5m / s, the windbreak will be lowered to avoid blocking the light and promote the growth of seedlings.

[0074] Data recording: Store wind speed data via SD card or remote platform to provide a basis for ecological restoration effect evaluation.

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

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

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

[0078] Wind speed sensors, through the integrated technology of high-precision monitoring, rapid response, and intelligent control, provide reliable wind speed data for grassland ecological restoration devices. Their technical advantages lie in measurement accuracy, environmental adaptability, control logic, and cost-effectiveness. They are a core component in devices that implement dynamic protection and improve 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 sequentially arranged, and a windproof shelter is arranged around the ecological part; the ecological part includes multiple ecological frames 7, and the multiple ecological frames 7 are laid on the water replenishment part. The adjacent ecological frames 7 are detachably connected by connecting parts, and the interior of the ecological frame 7 is sequentially laid with a water absorption layer, a matrix layer 14 and a matrix protection 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 energy component. The sensing control module and the lifting part are electrically connected to the solar energy component. 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 a first grid plate 2 laid on the soil base. The first grid plate 2 and the ecological frame 7 are both molded from coconut fiber, are degradable and do not pollute the environment. The windbreak shelter of the present invention can be reused after vegetation restoration and will not affect the ecology. The solar energy component consists of a solar photovoltaic panel and a battery, which can continuously provide power for the windbreak shelter. The sensing module is integrated with a wind speed sensor 16 and a controller, and is installed on the fixed part.

[0081] The sensing control module monitors the wind speed in real time and automatically adjusts the height of the windproof part through the lifting part, so that the windproof board can be quickly raised in strong winds and lowered in weak winds to avoid blocking the light, thereby preventing the stems of the seedlings from being broken; the water in the water supply part is collected and stored through the water absorption layer to provide sufficient water for the growth of the seedlings; the modular ecological frame 7 facilitates on-site construction and improves construction efficiency; the matrix protection layer can stabilize the matrix to prevent the roots of the seedlings from being exposed and losing water.

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

[0085] In this embodiment, the telescopic member 8 is an electric push rod.

[0086] When the wind speed detected by the wind speed sensor 16 in the sensing module exceeds a preset threshold, the information is transmitted to the controller, which controls the multiple telescopic members 8 to extend synchronously, raising the wind shield to protect the seedlings. When the wind returns to a light breeze or no wind, the controller controls the multiple telescopic members 8 to retract synchronously, retracting the wind shield into the groove. It should be noted that there are multiple wind speed sensors 16, each detecting wind from different directions.

[0087] Furthermore, the windproof portion includes a frame 5 slidably connected in the groove, a windproof plate 15 is connected in the frame 5, and a plurality of air discharge ports are provided on the windproof plate 15.

The pad 6 is made of recycled plastic or rubber with a bearing capacity of ≥200kg / m 2 , ensure the distance between the drip irrigation tape and the water retaining agent layer.

[0091] The water-stop membrane is made of degradable material, which can block water infiltration and reduce deep leakage losses. The drip irrigation belt 17 supplies water to the water-retaining agent 13. The water-retaining agent 13 absorbs water and expands to store water. It forms a water storage system with the water-retaining agent 13 at the bottom of the ecological frame 7 to provide sufficient water for the roots of the seedlings.

[0092] Furthermore, in order to achieve modular rapid assembly, the connecting part is an elastic splint 12, the ecological frame 7 is a rectangular frame, and long holes 10 are opened on all four sides of the ecological frame 7. The elastic splint 12 is snap-fitted with the long holes 10 to achieve stable fixation between the ecological frames 7. When the seedlings grow up, the elastic splint 12 is removed and recycled.

[0093] Furthermore, semicircular notches 11 are provided around the eco-frame 7 , and the semicircular notches 11 on two adjacent eco-frames 7 enclose a circular cavity, in which eco-pins 18 are inserted, and the eco-frame 7 is fixed to the water supply part through the eco-pins 18 .

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