DETAILED DESCRIPTION

[0020] The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. The embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0021] like Figures 1 to 6As shown, the present invention discloses a device for ecological restoration of degraded grassland, including a telescopic hydraulic prop 1, a solar energy device 2, a rain collection device 3 and a sensor system 11, wherein the telescopic hydraulic prop 1 is composed of a plurality of nested support rods, and the two connected support rods are connected by a hydraulic sealed bearing. The height of the telescopic hydraulic prop 1 can be adjusted by hydraulic control or mechanical manual control, so that the multi-section support rods can be extended or contracted up and down along the height direction of the telescopic hydraulic prop 1 according to the required height, so as to adapt to changes in different terrains and grassland environments. The solar energy device 2 includes a frame 21 and a plurality of solar panels 22, and the frame 21 is square -shaped structure, multiple solar panels 22 are snapped onto the frame 21, and the frame 21 is rotatably connected to the support rod at the top of the telescopic hydraulic support 1. During the assembly process, there is a preset angle between the frame 21 and the telescopic hydraulic support 1. The operator adjusts the preset angle according to the change in the angle of the sun's radiation, so that the multiple solar panels 22 face the sun and absorb sunlight, thereby increasing the exposure area of ​​the solar panels 22 and ensuring effective light utilization around the clock. At the same time, the solar panels adjusted at the preset angle can also partially shade the vegetation on the grassland under light, thereby preventing the vegetation from absorbing excessive light energy, thereby improving the vegetation growth rate and absorption rate of the grassland.

[0022] Continue to refer Figures 1 to 6 A rainwater collecting device 3 is installed on one side of the frame 21. The rainwater collecting device 3 includes a collecting trough 31, a diversion pipe 32 and a water storage tank 33. The rainwater collecting device 3 provides an additional water source for the grassland by collecting and storing rainwater for watering the vegetation on the grassland. The collecting trough 31 is connected to the water storage tank 33 through the diversion pipe 32. The collecting trough 31 is connected to the frame 21, and the collecting trough 31 is used to collect rainwater on the solar panel 22. In one example, the collecting trough 31 is located on the side of the frame 21 and is fixedly connected to the frame 21. The diversion pipe 32 is connected to the water storage tank 33. One end is connected to the collection trough 31, and the other end is connected to the water storage tank 33, so that the collection trough 31 and the water storage tank 33 are connected. The guide pipe 32 is responsible for quickly guiding the collected rainwater into the water storage tank 33 for storage and subsequent use. In one example, the collection trough 31 is located at the top of the frame 21. Along the width direction of the collection trough 31, the top surface of the collection trough 31 and the surface of the solar panel 22 are located at the same horizontal plane. During the use of the device, rainwater falls on the solar panel 221 and can slide into the collection trough 31, thereby effectively collecting rainwater.

[0023] When the device is used on a sunny day, the solar panel 22 absorbs sunlight and generates electricity for the device to work, and provides continuous electricity for the device to avoid intermittent operation of the device affecting subsequent operations. When a certain amount of electricity is absorbed, the solar device 2 will store the excess electricity for subsequent use. When the device is used on a rainy day, rainwater falls on the solar panel 22 and slides into the rain collecting device 3. It is collected by the collecting trough 31 of the rain collecting device 3 and flows into the diversion pipe 32. The diversion pipe 32 quickly guides the rainwater into the water storage tank 33 for storage. The stored rainwater can be used to provide water for vegetation in the grassland, or for other parts of the device, such as cleaning equipment, adjusting temperature and humidity, etc. The rainwater in the water storage tank 33 is supplied according to the moisture demand of the grassland, avoiding frequent dependence on external water replenishment.

[0024] like Figure 1 and Figure 2 As shown, in one example, an angle adjustment mechanism 4 is provided on the top of the telescopic hydraulic support 1. The angle adjustment mechanism 4 is used to adjust the tilt angle of the solar device 2 to adapt to different work requirements. The angle adjustment mechanism 4 is mainly composed of a ring gear 41 and a pinion 42. The two parts cooperate with each other to achieve precise angle adjustment. Among them, the ring gear 41 is installed on the top of the telescopic hydraulic support 1. The peripheral gear structure of the ring gear 41 is tightly matched with the meshing part of the pinion 42. The pinion 42 is connected to the frame 21 through a connecting shaft. Driving the ring gear 41 can drive the pinion 42 to rotate, so that the solar device 2 rotates relative to the support rod. The operator can accurately adjust the angle of the solar device 2 as required to meet the needs of different terrains and work, thereby improving the adaptability and flexibility of use of the device.

[0025] In another example (not shown in the drawings), the solar energy device is rotatably connected to the telescopic hydraulic support via a connector. The connector may be a spherical joint connector or a universal structure connector, so that the solar energy device can rotate freely along the radial direction of the telescopic hydraulic support 1, thereby adjusting the position of the solar energy device.

[0026] like Figure 1 and Figure 6 As shown, the device also includes a sensing system 11, which can be a soil moisture sensor, a temperature sensor, a light sensor, etc., as long as it can detect grassland-related parameters as needed. The sensing system 11 is set on the grassland to monitor various grassland data in real time. The sensing system 11, the rain collection equipment 3 and the solar energy equipment 2 are all electrically connected to the controller 10.

[0027] The present application achieves mutual cooperation between solar panels and rain-collecting equipment. As the ecology of the grassland changes, the device continuously monitors and collects environmental data through a sensor system, and feeds back to the controller in real time. The controller intelligently analyzes the grassland status based on the data, and the operator adjusts the preset angle of the solar equipment based on the analysis results, so that the solar panels of the solar equipment can continuously absorb solar energy. At the same time, the solar panels also serve as shade and rain-collecting equipment for the grassland, thereby effectively ensuring the growth of grass and promoting the ecological restoration of the grassland, thereby realizing the automation and intelligence of the device.

[0028] Preferably, continue to refer to Figure 1 and Figure 2 , the angle adjustment mechanism 4 also includes an electric motor 43, the output end of the electric motor 43 is connected to the connecting shaft, and the electric motor 43 is driven to rotate the solar device 2 relative to the telescopic hydraulic support 1 at a preset angle of 20°-50°. In one example, the solar device 2 rotates relative to the telescopic hydraulic support 1 at a preset angle of 37°. When it rains, rainwater can quickly slide from the solar panel 22 into the collection tank 31 to collect rainwater, thereby improving the efficiency and utilization of rainwater collection. In another example, the solar device 2 rotates relative to the telescopic hydraulic support 1 at a preset angle of 45°. When it is sunny, the solar panel 22 can obtain more sunlight, thereby effectively converting it into electrical energy for use by the device.

[0029] Preferably, Figure 1 and Figure 3 , Figure 4 As shown, the bottom of the collecting tank 31 has a plurality of through holes 311, and the plurality of through holes 311 are arranged at intervals along the extension direction of the collecting tank 31. The guide pipe 32 is connected to the inside of the collecting tank 31 through the through holes 311, so that rainwater in the collecting tank 31 flows into the guide pipe 32 through the through holes 311, thereby avoiding water accumulation in the collecting tank 31. The shape of the through hole 311 can be adaptively set as needed, for example, it can be a circular structure or a square structure, etc., as long as it can match the guide pipe 32. During use, the operator can remove the guide pipe 32 from the collecting tank 31 at any time to replace the guide pipe 32 and clean the collecting tank 31.

[0030] Preferably, the device is further provided with a sealing assembly 5, for example, Figure 6As shown, the sealing component 5 is a sealing ring, and a sealing ring is provided between the collecting tank 31 and the guide tube 32. The sealing ring can effectively prevent rainwater from leaking at the connection, thereby ensuring the long-term stable use of the equipment. At the same time, the sealing ring also has the function of buffering and stabilizing the structure, preventing the connection between the collecting tank 31 and the guide tube 32 from loosening and deformation when being impacted or pressurized by external forces. For another example (not shown in the figure), there is a sealing component at the connection between the frame and the solar panel to ensure the durability and water tightness of the solar equipment. The solar panels in the solar equipment are usually exposed to the external environment. The sealing component provides strength at the connection between the frame and the solar panel to prevent the loosening or deformation of the connection due to external pressure or climate change. Especially in an environment with strong wind or more rain, the sealing component can ensure the stability and durability of the solar panel. At the same time, the sealing component can also prevent moisture from penetrating into the circuit part of the solar equipment, prevent electrical short circuit or system failure, and improve the safety of the equipment.

[0031] Preferably, the collecting trough 31 is in a V-shaped structure or a U-shaped structure, ensuring that rainwater can be quickly and effectively collected during precipitation and transported to the water storage tank 33 through the guide pipe 32. In one example, Figure 1 and Figure 6 As shown, the collection trough 31 is a U-shaped structure. The collection trough 31 with a U-shaped structure can carry a large amount of rainwater, can gather water flow in a large area during precipitation and ensure that the water flow is unobstructed, and can ensure that the grassland can continue to obtain water during the dry season or when water is scarce, provide the irrigation support required by the grassland, and promote the ecological restoration of the grassland. In another example (not shown in the attached figure), the collection trough is a V-shaped structure. The collection trough with a V-shaped structure can quickly gather rainwater to the bottom of the trough. Due to the large inclination angle of the trough wall, the water flows rapidly downward under the action of gravity, reducing the stagnation time of the water flow in the collection trough, avoiding the accumulation of rainwater in the trough, and thus improving the efficiency of guiding the water flow.

[0032] Preferably, Figures 1 to 4As shown, the water storage tank 33 adopts a double-layer structure. Due to the strong sunlight in arid areas, the water source obtained is easy to evaporate. The water storage tank 33 includes an outer structure 331 and an inner structure 332. The inner structure 332 is coaxially arranged with the outer structure 331 to form an effective thermal insulation barrier, thereby reducing the impact of the external environment on the evaporation of the water source inside the water storage tank 33. The water storage tank 33 with a double-layer structure can effectively store rainwater, ensure that the water source can be preserved for a longer period of time, and provide a continuous irrigation water source for the vegetation in the grassland. Among them, the outer layer structure 331 is a high-strength engineering plastic, which has impact resistance, corrosion resistance and plasticity, such as polypropylene, polyethylene and other materials. The outer layer structure 331 provides a solid outer shell protection for the water storage tank 33, which can cope with changes and impacts in the external environment. The inner layer structure 332 is used to store rainwater. The inner layer structure 332 is made of stainless steel. Stainless steel can effectively prevent microorganisms and chemicals in the water from polluting the rainwater. It also has corrosion resistance, can maintain cleanliness for a long time and avoid water quality deterioration, thereby providing a clean and healthy water source for grassland irrigation.

[0033] Continue to refer Figure 1 and Figure 6 The water tank 33 is provided with a water inlet 333 and a water outlet 334 to facilitate the inflow and outflow of water. One end of the guide pipe 32 passes through the water inlet 333 and extends into the water tank 33, which can effectively guide the collected rainwater into the water tank 33, avoiding the waste of water resources. The water outlet 334 is located at the bottom of the side wall of the water tank 33. The operator inserts the irrigation pipe 6 into the water tank 2 through the water outlet, so that the rainwater is transported to the required grassland for irrigation through the irrigation pipe 6, thereby meeting the growth needs of the vegetation in the grassland.

[0034] Preferably, the inner layer structure 332 and the outer layer structure 331 are both cylindrical, and a matching shade plate 7 is provided in the inner layer structure 332. The shade plate 7 is used to block the contact between the external air and the rainwater, thereby effectively avoiding water pollution. During the assembly process, the shade plate 7 has holes, and the holes correspond to the water inlet 333. One end of the guide tube 32 passes through the water inlet 333 and the hole of the shade plate 7 and is placed in the water storage tank 33. When rainwater flows into the water storage tank 33, the shade plate 7 floats to the surface of the rainwater, thereby achieving a shading effect.

[0035] Preferably, Figures 1 to 6As shown, the side wall of the telescopic hydraulic support 1 is provided with a hydraulic system 8, the output end of the hydraulic system 8 is connected to the support rod, and the hydraulic system 8 generates pressure to drive the extension and retraction of the support rod by the flow of hydraulic oil in a closed loop, that is, the hydraulic system 8 is driven along the extension direction of the telescopic hydraulic support 1, so that the support rod is extended and retracted up and down. For example, the hydraulic system 8 is a hydraulic pump, and the hydraulic pump transmits hydraulic energy to the support rod through hydraulic oil. As the pressure of the hydraulic oil flows, the support rod is stretched or contracted up and down along the extension direction of the telescopic hydraulic support 1, so that the support rod can quickly adjust its length according to work needs and adapt to different environments and working conditions.

[0036] Preferably, continue to refer to Figures 1 to 6 , and also includes a water purification system 9, which is connected to the water storage tank 33. The water purification system 9 can efficiently remove impurities and pollutants in the water. During the use of the device, the water purification system 9 effectively purifies the rainwater in the water storage tank 33 to ensure that the water quality is clean and suitable for irrigating grasslands or other purposes, thereby providing better protection for the growth of vegetation on the grassland. In one example, it also includes a sensor system 11, which is used to detect various indicators of the land in the grassland to facilitate the operator to irrigate reasonably.

[0037] The solar device 2, the hydraulic system 8, the water purification system 9 and the sensor system 11 are all electrically connected to the controller 10. The controller 10 can monitor the operating status of each component in real time and coordinate and dispatch them through the electronic control system. The solar device 2 provides electrical energy to the controller. The controller 10 can control or drive the operation of the hydraulic system 8 and the water purification system 9, thereby ensuring that the entire device can maintain efficient and stable operation under different environmental conditions.

[0038] The working principle of a degraded grassland ecological restoration device in this application is: like Figures 1 to 6As shown, first, the telescopic hydraulic support 1 is installed at a predetermined position to ensure that the support rod is stable and can be smoothly extended and retracted. The supporting height of the telescopic hydraulic support 1 is adjusted according to work requirements, and the height of the telescopic hydraulic support 1 is adjusted through the hydraulic system. Then, the solar energy device 2 is installed, and the solar panel 22 is installed on the frame 21. The preset angle between the frame and the telescopic hydraulic support 1 is adjusted through the angle adjustment mechanism 4. On sunny days, the operator adjusts the angle of the solar panel 22 through the angle adjustment mechanism 4 according to the position of the sun to ensure that the solar panel 22 can absorb sunlight to the maximum extent, and convert the sunlight obtained by the solar panel 22 into electrical energy, so as to drive the hydraulic system 8 and the water purification system 9. When it is rainy, the operator adjusts the angle of the solar panel 22 again according to the weather conditions to better collect rainwater. The rainwater is collected by the rainwater collecting device 3 on one side of the frame 21. The rainwater slides into the collecting trough 31 of the rainwater collecting device 3 through the solar panel 22, and then flows into the water storage tank 33 through the guide pipe 32 for storage. The water storage tank 33 adopts a double-layer structure to effectively reduce water evaporation and improve the storage efficiency of water sources.

[0039] Next, the operator inserts the sensor system 11 into the grassland in the required area for subsequent detection. When the rainwater collection device 3 collects rainwater, the water purification system 9 removes impurities and pollutants in the rainwater in the water storage tank 33, thereby maintaining the required standard of water quality for the irrigation of vegetation in the grassland. The operator can transport rainwater to the required grassland area for irrigation through the irrigation pipe 6. The operator controls the controller 10 to monitor the operating status of all systems in real time and automatically adjust the work of each part according to environmental changes. For example, on sunny days, the controller 10 will give priority to using the electric energy converted by the solar panel 22 to drive the hydraulic system 8 and adjust the extension and retraction of the telescopic hydraulic support 1; on rainy days, the controller 10 automatically adjusts the working status of the rainwater collection device 3 to ensure that rainwater is collected and stored in time, so that the entire system can maintain efficient and stable operation under different environmental conditions, thereby realizing the restoration of the degraded grassland ecology.

[0040] Finally, the operator can regularly check the working status of the hydraulic system 8 and the water purification system 9 to ensure that the hydraulic system 8 is smooth and the water purification system 9 has a good filtering effect, and clean up the debris in the collection tank 31 and the guide pipe 32 to ensure that rainwater can flow smoothly into the water storage tank 33. At the same time, check the cleanliness of the solar panel 22 to prevent dust and debris from affecting the light absorption efficiency.

[0041] The present application provides a method for ecological restoration of degraded grassland, which comprises the following steps: Site selection: Select representative grassland areas with different levels of degradation, dig profiles in the selected areas, and analyze soil structure and properties; like Figures 7 to 13As shown, in this application, the Bashang area of ​​Zhangjiakou, Hebei Province was selected as the research object. This area has the production characteristics of both dryland farming and grassland animal husbandry. It is also an important water source for the downwind Beijing-Tianjin area and an important ecological safety barrier to prevent soil wind erosion and desertification expansion. It has very important ecological strategic significance. However, in recent years, the Bashang grassland has been affected by the combined influence of natural and human factors, significant temperature differences, dry air, strong winds, and frequent droughts, which have accelerated the desertification and alkalization of the soil, destroyed the grassland ecosystem, and seriously degraded the grassland grassland. At the same time, sensors are installed to analyze the characteristics of the soil in the grassland area to facilitate subsequent operations.

[0042] Installation: Install multiple rows of devices for ecological restoration of degraded grasslands, and connect the sensor systems in the devices to data collection stations to monitor grassland environmental parameters; The operators set up multiple rows of degraded grassland ecological restoration devices in the dam grassland area, and the interval between two adjacent rows of the degraded grassland ecological restoration devices was 12m. The preset angle between the solar panels 22 in the degraded grassland ecological restoration devices and the telescopic hydraulic support 1 was adjusted to 37°. The size of each solar panel 22 was 1.66m*0.95m, and each group of four was composed of a group. The length and width of the telescopic hydraulic support 1 were 20*cm10cm, and the height was adjusted to 3m to facilitate the growth of grass.

[0043] Planting: Plant grass according to the region, pre-treat the soil first, determine the grass seed combination and sowing density according to regional characteristics, cover with thin soil and water after sowing; The operator breaks the hard layer in the soil through tillage, loosening the soil, etc., enhances the permeability of the soil, facilitates the penetration of water and nutrients, and improves the growth space and breathing environment of the grass roots. The weeds in the grassland are then removed manually or mechanically to prevent them from competing with the grass seeds for water and nutrients. The removal of weeds helps the healthy growth of the lawn. At the same time, an appropriate amount of organic fertilizer or soil-improving materials (such as lime, compost, etc.) are added to the soil to make the pH value and nutrient status of the soil reach a level suitable for the growth of grass seeds. Before using the rainwater collected by the rainwater collection equipment 3 for irrigation, the operator uses the water purification system 9 to clean the rainwater, and finally transports the rainwater through the irrigation pipe 6 to the grassland area to be irrigated.

[0044] Sampling: Conduct soil sampling in grassland plots, including soil layer depth, wet soil weight, infiltration depth, and watering amount.

[0045] Operators take soil from grassland plots in various areas, such as Figure 7The following figure shows the parameters of soil sampling for each grassland plot, so as to obtain the overall situation of the soil in the grassland. The area of ​​each area should be determined according to the actual situation, usually between 1 square meter and 10 square meters, to ensure that the samples are representative. During the sampling process, the depth of the soil should be measured, especially for stratified sampling of soil at different depths. Common soil layers include topsoil layer (0-20 cm), middle soil layer (20-40 cm), deep soil layer (40-60 cm), etc. By analyzing the soil composition of different soil layers, it can help to understand the soil's water retention capacity, fertility status and whether the soil conditions at certain layers need to be improved. At the same time, the wet soil weight of each sample needs to be recorded during sampling for subsequent analysis of its impact on grass seed growth. Too much wet soil weight may mean that the soil is too compact, affecting the penetration of water and air, while too little wet soil weight may mean that the soil is too loose and has poor water retention capacity.

[0046] Infiltration depth refers to the depth of water penetration in the soil. It is an important indicator for measuring soil drainage and water retention capacity. By measuring the infiltration depth of the soil, we can understand the water infiltration capacity of the soil at different humidity levels and determine whether there is a problem of poor drainage. If the infiltration depth is too shallow, it means that there may be a clay layer or compaction in the soil, which needs to be improved. During the sampling process, the actual amount of watering needs to be recorded, and the amount of watering should be controlled between 0-10L in order to evaluate the rationality of the irrigation strategy. Excessive water may cause waterlogging and affect the root health of the lawn, while insufficient water may cause the grass seeds to develop poorly and wither. Therefore, a reasonable amount of watering and irrigation methods are important factors in ensuring healthy lawn growth.
