Description

Technical Field

[0001] This utility model relates to the field of seedling protection technology, and in particular to a seedling protection device. Background Technology

[0002] In the construction and operation of mountainous new energy projects, seedling protection is a crucial task. Seedlings are key elements for improving the ecological environment, preventing soil erosion, and optimizing soil quality; their healthy growth directly affects whether the project can meet water conservation acceptance standards and achieve overall ecological benefits. However, current seedling protection in mountainous new energy project sites faces many complex and interconnected technical challenges.

[0003] On the one hand, the unique climatic conditions in mountainous areas pose significant challenges to seedlings. Frequent and strong winds in mountainous regions easily cause seedlings to tilt, fall over, or even break branches. This not only significantly reduces the survival rate of seedlings and increases the cost of repeated planting, but also adversely affects the overall progress of the project and the effectiveness of ecological restoration. For example, in some mountainous new energy project sites, due to the impact of strong winds, a large number of seedlings fell over shortly after planting, necessitating substantial investment of manpower and resources for replanting and reinforcement.

[0004] On the other hand, the surrounding ecological environment also poses a threat to the seedlings. Wild animals and livestock such as cattle and sheep raised by villagers often graze on the seedlings. This behavior not only directly damages the growth of the seedlings but also seriously undermines soil and water conservation measures. Soil and water conservation measures play a crucial role in improving soil erosion and optimizing soil quality; once damaged, their effectiveness is greatly reduced, making it difficult for the project to meet soil and water conservation acceptance standards. Related studies have shown that in some areas severely affected by livestock grazing, the effectiveness of soil and water conservation measures has decreased by about 30%, leading to an exacerbation of soil erosion problems.

[0005] Existing methods for protecting seedlings also present numerous problems. Commonly used methods, such as installing fences throughout the entire area and manual patrols to deter livestock, suffer from drawbacks including being time-consuming, costly, and ineffective. Installing fences requires substantial material and manpower investment, and the fences may negatively impact the overall landscape and ecology of the area. Furthermore, fence maintenance is costly, and repairs are difficult once damaged. Manual patrols require continuous manpower, and their effectiveness is uncertain, especially at night or when personnel are not present, allowing livestock to enter the area and graze on the seedlings. Currently, no publicly available patents or literature have been found that effectively address these issues.

[0006] Existing protective supports for landscaping seedlings, such as the one disclosed in CN112544334A, while providing some support and protection, still have some shortcomings. Most of these supports have a fixed structure, making it difficult to flexibly adjust them according to the different heights and growth stages of the seedlings. In practical applications, seedlings grow taller as they grow, and fixed supports cannot adapt to this change, leading to a gradual weakening or even loss of support for the upper parts of the seedlings.

[0007] Meanwhile, existing protective supports for landscaping and saplings are inadequate for meeting the protection needs of saplings on slopes with different angles. The direction and magnitude of forces such as gravity and wind acting on the saplings change with the slope angle, and fixed protective supports cannot be adjusted according to the slope angle, making it difficult to provide effective support and protection for saplings on slopes with different angles.

[0008] Furthermore, existing protective supports for landscaping seedlings are not entirely effective in preventing animal grazing. Their design typically focuses on providing physical support for the seedlings, lacking effective protective measures against animal grazing. Wild animals and livestock can still easily access and graze on the seedlings, failing to fundamentally solve the problem of damage caused by animal grazing.

[0009] In summary, existing seedling protection technologies for mountainous new energy project sites, including existing protective supports for landscaping seedlings, have significant shortcomings and deficiencies in addressing strong winds, animal grazing, and the protection needs of different terrains and seedling sizes. Therefore, developing a seedling protection device that can effectively solve these problems is of great practical significance. Utility Model Content

[0010] This utility model provides a seedling protection device to solve the problems of tilting, falling, and branch breakage of green seedlings caused by strong winds in mountainous new energy project sites and similar environments, as well as the problem of wild animals and livestock gnawing and damaging the seedlings. Specifically, under the current technological background, there is a lack of a seedling protection device that can effectively adapt to the protection needs of seedlings at different heights and angles, prevent animals from gnawing, and is also cost-effective and easy to implement.

[0011] This utility model provides an adjustable seedling protection device to overcome the limitations of existing protective measures, such as poor effectiveness, high cost, and poor adaptability.

[0012] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows: A seedling protection device was designed, which mainly consists of two parts: an adjustable protective structure and an adjustable clamping structure. The specific structure and connection relationship are as follows: (a) Adjustable protective structure The adjustable protective structure is the core component of the device, enabling height adaptation, slope adaptation, and anti-gnawing protection. It includes a fixed connecting plate, a fixed connecting seat, a rotating support plate, fixed pins, a fixed sliding plate, a movable sliding plate, spring clips, a limiting groove, a connecting frame, a connecting rod, a movable connecting rod, and a connecting frame. The connection methods and functions of each component are as follows: Slope adaptation and ground fixing components: Fixed connecting seats are symmetrically connected to the side wall of the fixed connecting plate. The fixed connecting seats are rotatably connected to the rotating support plate through the rotating shaft, which can realize the folding and angle adjustment of the rotating support plate to adapt to slope terrain with different angles. Both the fixed connecting plate and the rotating support plate are provided with enlarged holes that cooperate with the fixed pins. The fixed pins and the enlarged holes are clearance fit. When in use, the fixed pins are passed through the enlarged holes and driven into the ground to complete the stable fixing of the device to the ground.

[0013] Height adjustment component: A fixed sliding plate is connected to the side wall of the fixed connecting plate. The inner cavity of the fixed sliding plate is slidably connected to the movable sliding plate. A spring buckle is installed in the inner cavity of the movable sliding plate. Multiple sets of limiting grooves corresponding to the spring buckles are opened on the side wall of the fixed sliding plate, and the spring buckles and the limiting grooves are clearance fit. By sliding and adjusting the relative position of the fixed sliding plate and the movable sliding plate, after adjusting to the appropriate height of the seedling, the spring buckle is snapped into the corresponding limiting groove, so that the height of the two can be fixed to meet the protection needs of seedlings of different heights.

[0014] Anti-grazing and protective reinforcement components: The top of the movable sliding plate is connected to a connecting frame, and multiple sets of connecting rods are connected to the connecting frame. The inner cavity of the connecting rod is slidably connected to the movable rod. A connecting frame is connected to the side wall of the movable rod, and fixing nails are installed at the bottom of the movable rod and the front of the connecting frame. By sliding and adjusting the relative position of the connecting rod and the movable rod, the height of the connecting frame can be adjusted so that it surrounds the seedling to form a protective barrier to prevent animals from grazing on the seedling. At the same time, driving the fixing nails at the bottom of the movable rod into the ground can further enhance the stability of the connecting frame, improve the overall wind resistance of the device, and prevent the seedling from falling over due to strong winds.

[0015] (ii) Adjustable clamping structure The adjustable clamping structure is used to stably clamp seedlings of different diameters, preventing them from swaying or shifting in strong winds. It includes a connecting housing, a rotating screw, a rotating knob, a shaft retainer, a moving slider, a limiting slide rod, a connecting rod, an arc-shaped connecting plate, a telescopic spring, and a fixing plate. The connection methods and functions of each component are as follows: Drive and transmission components: The connecting housing is fixed to the side wall of the fixed slide plate. A rotating screw is mounted on the connecting housing via a bearing seat, and the rotating screw is rotatably connected to the bearing seat to ensure stable rotation without deviation. A rotating knob is connected to one end of the rotating screw for easy manual operation. A shaft retainer is installed on the side wall of the connecting housing and the cylindrical surface of the rotating screw to limit the axial displacement of the rotating screw. The rotating screw is composed of a left-hand screw and a right-hand screw, and movable sliders are symmetrically connected to its side wall, with the rotating screw and movable sliders connected by threads. When the rotating knob drives the rotating screw to rotate, the two sets of movable sliders will move relative to or away from each other along the axis of the rotating screw to achieve spacing adjustment.

[0016] Limiting and guiding components: Symmetrical connecting holes are provided on the movable slider, and limiting slide rods are slidably connected in the connecting holes. The two ends of the limiting slide rods are fixed on the side wall of the inner cavity of the connecting housing to limit the movement direction of the movable slider and prevent the movable slider from deflecting as the rotating screw rotates. The side wall of the connecting housing is provided with a slide groove corresponding to the connecting rod. One end of the connecting rod is connected to the movable slider, and the other end passes through the slide groove and is connected to the arc-shaped connecting plate through the connecting seat. The connecting rod is slidably connected to the slide groove, and the slide groove provides guidance for the movement of the connecting rod to ensure the stable movement of the arc-shaped connecting plate.

[0017] Adaptive clamping assembly: Multiple sets of telescopic springs are connected to the inner wall of the arc-shaped connecting plate, and the other end of the telescopic springs is connected to a fixed clamping plate; when the moving slider drives the connecting rod and the arc-shaped connecting plate to move, so that the fixed clamping plate contacts the seedling, the telescopic spring can adaptively deform according to the diameter of the seedling, which can not only ensure the stable clamping of the seedling by the fixed clamping plate, but also avoid damage to the seedling surface due to excessive clamping force, thus realizing the adaptive clamping of seedlings of different diameters.

[0018] The seedling protection device provided by this utility model has the following beneficial effects: 1. This utility model effectively solves the existing technical problems of seedling protection in mountainous new energy project sites, including the reduction of survival rate due to seedling tilting, falling, and broken branches caused by strong winds in mountainous areas; the damage to water conservation measures caused by wild animals and livestock in the surrounding area, affecting the project's water conservation acceptance standards and increasing construction costs; the time-consuming, costly, and ineffective nature of existing protection methods; and the inability of existing seedling protection devices to adapt to the protection needs of slopes with different angles and seedlings of different heights and diameters.

[0023] 6. This utility model provides water conservation measures to facilitate project acceptance. By effectively protecting seedlings, it prevents damage that could render the water conservation measures ineffective, ensuring their proper functioning and helping the project meet water conservation acceptance standards. It also reduces the need for repeated planting of seedlings and lowers project costs.

[0027] 10. The newly added telescopic spring design of this utility model can provide buffer when the seedling is subjected to external force, preventing the seedling from breaking due to excessive instantaneous force. At the same time, during the normal growth of the seedling, the clamping force is automatically adjusted according to the slight movement of the seedling to ensure that the seedling is in the best growth environment.

[0028] 11.

Detailed Implementation

[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments: Example 1 like Figures 1 to 5 As shown, this embodiment provides a seedling protection device, specifically applicable to the protection of green seedlings with a height of approximately 1.5 meters and a diameter of approximately 5 centimeters in mountainous new energy project areas. The device comprises two parts: an adjustable fixing structure 1 and an adjustable clamping structure 2.

[0036] 1. Adjustable Fixing Structure 1: First, fix the fixing plate 101 to the slope with bolts. A fixing connecting seat 102 is installed on the fixing plate 101. Adjust the angle of the rotating support plate 103 according to the slope angle (assumed to be 30 degrees), and fix the rotating support plate 103 to the fixing connecting seat 102 with fixing pins 104 to ensure the device is stable. Next, adjust the height between the fixed sliding plate 105 and the movable sliding plate 106 according to the height of the seedlings. The movable sliding plate 106 can slide on the fixed sliding plate 105. When a suitable height is reached (approximately 1.6 meters, suitable for 1.5-meter-high seedlings with some leeway), fixation is achieved by the spring buckle 107 engaging with the limiting groove 108 on the fixed sliding plate 105. At this point, the protective frame consisting of the connecting frame 109, connecting rod 110, movable rod 111, and connecting frame 112 is completed. The connecting frame 109 is connected to the movable slide plate 106, the connecting rod 110 connects the connecting frame 109 and the movable rod 111, and the movable rod 111 is then connected to the connecting frame 112, forming a stable whole that can effectively resist the impact of strong winds on the seedlings.

[0037] 2. Adjustable clamping structure 2: The connecting housing 201 is fixed to the connecting frame 112. A rotating screw 202 is installed inside the connecting housing 201. A rotating knob 203 is installed at one end of the rotating screw 202, and the other end is fixed to the connecting housing 201 through a shaft retainer 204. By rotating the rotating knob 203, the rotating screw 202 is rotated, which drives two sets of moving sliders 205 to move relative to each other along the limiting slide rod 206. The limiting slide rod 206 is fixed inside the connecting housing 201, which restricts the movement direction of the moving sliders 205. The position of the moving sliders 205 is adjusted according to the diameter of the seedlings. The moving sliders 205 are connected to the arc-shaped connecting plate 208 through the connecting rod 207. A telescopic spring 209 is installed on the arc-shaped connecting plate 208, and the other end of the telescopic spring 209 is connected to the fixing clamp 210. When the movable slider 205 moves, it causes the arc-shaped connecting plate 208 and the fixed clamping plate 210 to fit tightly against the seedling, and provides additional clamping force through the telescopic spring 209 to ensure that the seedling is stable and does not fall over.

[0038] Example 2 In another preferred embodiment, based on Embodiment 1 above, this embodiment provides a seedling protection device suitable for protecting green seedlings with a height of approximately 2 meters and a diameter of approximately 8 centimeters in plain areas. This device also includes an adjustable fixing structure 1 and an adjustable clamping structure 2.

[0039] 1. Adjustable Fixing Structure 1: On flat ground, the fixing plate 101 can be directly fixed to the ground with anchor bolts. The fixing connecting seat 102 on the fixing plate 101 is used to connect the rotating support plate 103. Depending on the height of the seedlings, the height between the fixing slide plate 105 and the moving slide plate 106 is adjusted to approximately 2.1 meters (suitable for 2-meter-high seedlings with some leeway), and fixed to the limiting groove 108 via spring buckles 107. Since it is on flat ground, the rotating support plate 103 can be adjusted to a horizontal position and fixed to the fixing connecting seat 102 via fixing pins 104 to provide additional stability. At this point, the protective frame consisting of the connecting frame 109, connecting rod 110, moving rod 111, and connecting frame 112 is completed, providing a stable structure and effective protection for the seedlings.

[0040] 2. Adjustable clamping structure 2: Similar to embodiment 1, the connecting housing 201 is fixed to the connecting frame 112. However, for seedlings with larger diameters, the rotating knob 203 needs to be rotated further to rotate the rotating screw 202, causing the moving slider 205 to move relative to the limiting slide bar 206, which in turn moves the arc-shaped connecting plate 208 and the fixing clamp 210 closer to the seedling. This continues until the fixing clamp 210 is tightly fitted to the seedling, and sufficient clamping force is provided by the telescopic spring 209. The telescopic spring 209 plays a crucial role in this process, automatically adjusting the clamping force according to the slight movement of the seedling to ensure that the seedling remains stable.

[0041] Example 3 In another preferred embodiment, based on embodiments 1 and 2 above, this embodiment provides a seedling protection device suitable for seedling protection on gentle terraces in mountainous new energy projects. Its specific structure and installation and adjustment steps are as follows: I. Structural Composition (See attached document) Figures 1 to 5 ) The core structure of the seedling protection device used in this embodiment consists of an adjustable protection structure 1 and an adjustable clamping structure 2. The assembly relationship and position of each component can be clearly seen in the corresponding drawings. The specific structure is as follows: 1. Adjustable protective structure 1, see reference Figures 1 to 3 The system includes a fixed connecting plate 101, a fixed connecting seat 102, a rotating support plate 103, a fixed pin 104, a fixed sliding plate 105, a movable sliding plate 106, a spring buckle 107, a limiting groove 108, a connecting frame 109, a connecting rod 110, a movable connecting rod 111, and a connecting frame 112. The fixed connecting plate 101 is the basic support component. The fixed connecting seat 102 is symmetrically welded to the side wall of the fixed connecting plate 101. The rotating support plate 103 is rotatably connected to the fixed connecting seat 102 via a rotating shaft. The fixed sliding plate 105 is vertically welded to the middle of the side wall of the fixed connecting plate 101. The movable sliding plate 106 is nested within the inner cavity of the fixed sliding plate 105. The connecting frame 109 is welded to the top of the movable sliding plate 106. One end of the connecting rod 110 is bolted to the connecting frame 109, and the other end is nested within the movable connecting rod 111. The connecting frame 112 is welded to the end of the movable connecting rod 111 away from the connecting rod 110.

[0042] 2. Adjustable clamping structure 2, see reference Figure 4 and Figure 5 The system includes a connecting housing 201, a rotating screw 202, a rotating knob 203, a shaft retainer 204, a movable slider 205, a limiting slide bar 206, a connecting rod 207, an arc-shaped connecting plate 208, a telescopic spring 209, and a fixing clamp 210. The connecting housing 201 is bolted to the side wall of the fixing slide plate 105. The rotating screw 202 is installed inside the connecting housing 201 via a bearing seat. The rotating knob 203 is welded to one end of the rotating screw 202. The shaft retainer 204 is sleeved on... The rotating screw 202 is bolted to the middle and connected to the inner wall of the connecting housing 201. The movable slider 205 is symmetrically sleeved on both sides of the rotating screw 202 (threaded to the rotating screw 202). The limiting slider 206 passes through the movable slider 205 and is welded to the inner wall of the connecting housing 201. One end of the connecting rod 207 is hinged to the movable slider 205, and the other end is hinged to the arc-shaped connecting plate 208. One end of the telescopic spring 209 is welded to the inner wall of the arc-shaped connecting plate 208, and the other end is welded to the outer wall of the fixed clamping plate 210.

[0043] II. Installation and Debugging Steps Step 1: Installation and commissioning of adjustable protective structure 1 (refer to...) Figure 2 and Figure 3 ) Step 1.1, Foundation Fixing: Select a level surface next to the sapling, place the fixing plate 101 flat, ensuring it is in contact with the ground; according to Figure 3 Assemble the fixing pin 104 with the fixing connecting plate 101 and the rotating support plate 103. Unfold the rotating support plate 103 so that the rotating support plate 103 and the fixing connecting plate 101 form a 110° angle. Pass the fixing pin 104 through the enlarged holes of the fixing connecting plate 101 and the rotating support plate 103, and hammer it vertically into the ground for 28cm~32cm. Fix at least 2 fixing pins 104 to each plate to ensure that the fixing pins 104 are stable and not loose.

[0044] Step 1.2, Height Adjustment: Based on the seedling height (0.7m in this example), refer to... Figure 2 The sliding relationship between the fixed sliding plate 105 and the movable sliding plate 106 is determined by pulling the movable sliding plate 106 upwards, causing it to slide along the inner cavity of the fixed sliding plate 105. Observe the engagement state between the spring buckle 107 and the limiting groove 108. When the height of the connecting frame 109 reaches 0.8m, the spring buckle 107 springs into the corresponding limiting groove 108, completing the height locking. Pull the connecting frame 112 to drive the movable connecting rod 111 to slide along the connecting rod 110, adjusting the height of the connecting frame 112 to 7cm~9cm above the bottom of the seedling. Then, drive the fixing nail at the bottom of the movable connecting rod 111 into the ground 22cm~25cm to fix the connecting frame 112.

[0045] Step 2: Installation and debugging of adjustable clamping structure 2 (refer to...) Figure 4 and Figure 5 ) Step 2.1, Structural Fixing: The two sets of connecting shells 201 are symmetrically fixed to the side wall of the fixed plate 105 with bolts, ensuring that the connecting shells 201 are perpendicular to the fixed plate 105 and that the distance between the two sets of structures and the seedlings is consistent.

[0046] Step 2.2, Clamping Adjustment: Hold the rotating knob 203 and rotate it clockwise to rotate the rotating screw 202. Since the rotating screw 202 has a left-hand + right-hand combination structure, the moving slider 205 moves along the limiting slider 206 towards the seedling, and through the connecting rod 207, it drives the arc-shaped connecting plate 208, the telescopic spring 209, and the fixed clamping plate 210 to approach the seedling. After the fixed clamping plate 210 contacts the seedling, continue to slowly rotate the rotating knob 203 until you feel slight resistance. At this time, the telescopic spring 209 is compressed to generate a clamping force of 2.5N~3.5N. Check the shaft retainer 204 to ensure that it is tightly attached to the connecting housing 201 to limit the axial displacement of the rotating screw 202, and complete the clamping adjustment.

[0047] Step 2.3, Overall Inspection: Shake the fixed connecting plate 101 and the connecting frame 112 to check if they are stable; observe the contact state between the fixed clamp 210 and the seedling to ensure that there is no excessive compression; confirm that there is no jamming in each sliding part, and that the limiting parts such as the spring buckle 107 and the shaft retainer 204 are functioning normally, and complete the overall installation and debugging.

[0048] Example 4 In another preferred embodiment, based on embodiments 1 and 2 above, this embodiment provides a seedling protection device suitable for gentle slope areas with a slope of 5° to 15° in mountainous new energy projects. This area is planted with arborescent seedlings with a height of 1.2m to 1.8m and a trunk diameter of 5cm to 10cm. This area is affected by mountain monsoons, with a high number of windy days per year, and there are grazing cattle and sheep belonging to villagers nearby, posing a risk of seedlings being blown down or eaten by livestock. Therefore, a protection device is needed to ensure the survival rate of the seedlings and to ensure the effectiveness of water conservation measures in the area.

[0049] The installation and adjustment steps for this device are as follows: Step 1: Installation and adjustment of adjustable protective structure 1 Step 1.1, Slope Adaptation and Ground Fixation: Place the fixing plate 101 on the ground to one side of the seedling. According to the slope angle (10° in this embodiment), manually rotate the rotating support plate 103 on the fixing connecting seat 102 to make the rotating support plate 103 fit against the slope ground. Then, pass the fixing pin 104 through the enlarged holes on the fixing plate 101 and the rotating support plate 103, and use a hammer to drive the fixing pin 104 into the ground 30cm~40cm to complete the initial fixation of the device to the ground.

[0050] Step 1.2, Adjusting the height to match the seedling height: In this embodiment, the seedling height is 1.5m. Manually pull the movable slide plate 106 upwards so that the movable slide plate 106 slides along the inner cavity of the fixed slide plate 105. At the same time, observe the position of the spring buckle 107. When the height of the connecting frame 109 at the top of the movable slide plate 106 reaches 1.6m (10cm higher than the top of the seedling to ensure that the protection range covers the top of the seedling), the spring buckle 107 will be engaged in the corresponding limiting groove 108 on the side wall of the fixed slide plate 105 under its own elasticity, thereby locking the height of the fixed slide plate 105 and the movable slide plate 106.

[0051] Step 1.3, Adjustment of anti-grazing protection components: Pull down the connecting frame 112 to move the moving link 111 along the inner cavity of the connecting link 110. When the height of the connecting frame 112 drops to 10cm~15cm above the bottom of the seedling (to prevent the accumulation of ground debris from affecting the protective effect), stop pulling. Then, use a hammer to drive the fixing nail at the bottom of the moving link 111, which is located directly in front of the connecting frame 112, into the ground 25cm~30cm deep, so that the connecting frame 112 surrounds the seedling to form a closed protective barrier to prevent cattle and sheep from grazing on the seedling trunk and lower branches and leaves.

[0052] Step 2: Installation and adjustment of adjustable clamping structure 2 Step 2.1, Clamping Spacing Adjustment: Fix the connecting shells 201 of the two sets of adjustable clamping structures 2 to the side walls of the fixed sliding plate 105 respectively, with the two sets of structures symmetrically distributed on both sides of the seedling. Manually rotate the rotating knob 203 to drive the rotating screw 202 to rotate. Since the rotating screw 202 is composed of a left-handed screw and a right-handed screw, the two sets of moving sliders 205 move relative to each other along the limiting slide bar 206, which drives the arc-shaped connecting plate 208 and the fixed clamping plate 210 to move towards the seedling through the connecting rod 207.

[0053] Step 2.2, Adaptive Clamping and Fixing: When the fixing plate 210 contacts the tree trunk, continue to slowly rotate the rotating knob 203 until a slight resistance is felt. At this time, the telescopic spring 209 undergoes elastic deformation due to the pressure of the tree trunk, generating a clamping force of 5N~8N. This ensures that the fixing plate 210 stably clamps the tree trunk, preventing the tree from swaying in the wind, while also avoiding excessive clamping force that could damage the tree trunk bark. Finally, check the shaft fixer 204 to ensure that the rotating screw 202 has no axial displacement, completing the clamping and fixing process.

[0054] After installation, the connecting frame 112 forms a 1.5m high protective barrier around the seedlings, effectively preventing cattle and sheep from approaching and grazing. The device is double-fixed to the ground by the fixing pins 104 and the bottom fixing nails of the moving connecting rod 111, combined with the adjustable clamping structure 2 to stably clamp the seedlings. When the wind force reaches level 6, the seedlings do not tilt significantly and there are no broken branches on the trunks. After 3 months of use and observation, the survival rate of the seedlings is over 95%, and there are no cases of seedling death due to livestock grazing or wind damage. The water conservation measures in the area have not failed due to seedling damage.

[0055] Example 5 In another preferred embodiment, based on embodiments 1 and 2 above, this embodiment provides a seedling protection device suitable for steep slope areas with a gradient of 20° to 30° in mountainous new energy projects. This area is planted with shrubs and greening seedlings with a height of 0.8m to 1.2m and a trunk diameter of 3cm to 6cm. The terrain in this area has a large slope, making it difficult to stably fix traditional protection devices. Furthermore, wild animals such as rabbits and squirrels are present in the surrounding area, easily nibbling on the tender branches of the seedlings. At the same time, the soil stability in steep slope areas is poor, and strong winds can easily cause the seedlings to fall over along with the soil around their roots, severely damaging the site's water conservation measures.

[0056] The installation and adjustment steps for this device are as follows: Step 1: Adjusting and installing the protective structure 1 Step 1.1, Slope Adaptation and Ground Fixation: Place the fixing plate 101 against the steep slope. Depending on the slope angle (25° in this embodiment), slowly rotate the rotating support plate 103 on the fixing connecting seat 102 to make the rotating support plate 103 fit tightly against the ground on the other side of the steep slope. Due to the large slope, two fixing pins 104 need to be inserted into the enlarged holes of the fixing plate 101 and the rotating support plate 103. Use a hammer to drive the fixing pins 104 into the ground at an angle of 40cm to 50cm (the angle of inclination should be consistent with the slope to enhance the stability of the fixation) to ensure that the device has no risk of slipping on the steep slope.

[0057] Step 1.2, Height Adjustment to Adapt to Seedling Height: In this embodiment, the seedling height is 1.0m. Manually pull the movable slide plate 106 to slide it along the fixed slide plate 105. When the height of the connecting frame 109 reaches 1.1m, the spring buckle 107 engages with the corresponding limiting groove 108, completing the height fixation. Since shrub seedlings have relatively dense branches, care should be taken during adjustment to avoid the movable slide plate 106 scratching the seedling branches.

[0058] Step 1.3, Adjustment of anti-gnawing protective components: Pull down the connecting frame 112 to make the moving link 111 slide along the connecting link 110. When the height of the connecting frame 112 drops to 5cm~8cm above the bottom of the seedling, stop pulling and tilt the fixing nail at the bottom of the moving link 111 into the ground 30cm~35cm to ensure that the connecting frame 112 can completely surround the seedling and prevent wild animals from crawling in and gnawing on the tender branches.

[0059] Step 2: Installation and adjustment of adjustable clamping structure 2 Step 2.1, Clamping Spacing Adjustment: Install the connecting shells 201 of the two sets of adjustable clamping structures 2 on the side wall of the fixed slide plate 105, and control the height difference between the two sets of structures to 20cm-30cm (to suit the height distribution of shrub seedling trunks). Manually rotate the rotating knob 203 to drive the rotating screw 202 to rotate, causing the two sets of moving sliders 205 to move relative to each other along the limiting slide bar 206, and through the connecting rod 207, drive the arc-shaped connecting plate 208 and the fixed clamping plate 210 closer to the trunk.

[0060] Step 2.2, Adaptive Clamping Fixation: After the fixing plate 210 contacts the tree trunk, continue rotating the knob 203 until a slight resistance is felt. At this time, the telescopic spring 209 undergoes elastic deformation, generating a clamping force of 3N~5N, suitable for the thinner trunks of shrub seedlings. Due to the poor root stability of seedlings in steep slope areas, after clamping and fixing, it is necessary to gently push the seedling trunk to check that the seedling does not wobble significantly, ensuring the stability of the clamping effect.

[0061] After installation, the device did not slip or tilt on steep slopes. The connecting frame 112 effectively prevented wild animals such as rabbits and squirrels from approaching the seedlings and prevented tender branches from being eaten. After being tested by strong winds (maximum wind force up to level 7), the seedlings did not fall over or break branches, and the soil around the roots did not show significant loosening. After 6 months of use, the seedling survival rate reached over 92%, the water conservation measures in the steep slope area of ​​the site remained intact, and the soil erosion was reduced by more than 60% compared with the unprotected area, meeting the water conservation construction requirements of the project.

[0062] In a preferred embodiment, fixed connecting seats 102 are symmetrically installed on the side wall of the fixed connecting plate 101, and rotating support plates 103 are connected to the fixed connecting seats 102. Both the fixed connecting plate 101 and the rotating support plate 103 are provided with fixing pins 104. Multiple sets of connecting rods 110 are connected to the connecting frame 109, and a movable connecting rod 111 is fitted inside the connecting rod 110. A connecting frame 112 is connected to the lower part of the movable connecting rod 111. This configuration allows the fixed connecting plate 101 and the rotating support plate 103 to be flexibly fixed and rotated using the fixing pins 104, meeting the support requirements at different angles. The cooperation of multiple sets of connecting rods 109 and movable connecting rods 111 allows the connecting frame 112 to be flexibly moved and adjusted, greatly improving the adaptability and practicality of the entire device.

[0063] In a preferred embodiment, the fixed connecting seat 102 and the rotating support plate 103 are rotatably connected by a rotating shaft, enabling the rotating support plate 103 to be folded and its angle adjusted to adapt to slope terrain with different angles. The above configuration allows the device to flexibly cope with complex and ever-changing slope conditions, greatly improving its adaptability. The stable design of the rotating shaft ensures the stability of the rotating support plate 103 during adjustment and use, providing a reliable guarantee for slope protection work.

[0064] In a preferred embodiment, guide holes are provided at the connection points between the fixed connecting plate 101 and the rotating support plate 103 and the fixed pin 104. The fixed pin 104 and the guide hole are fitted with a clearance fit. By passing the fixed pin 104 through the guide hole and nailing it into the ground, the device is fixed to the ground. The above arrangement can ensure the smooth insertion of the fixed pin 104, reduce installation resistance, and allow the device to have a small displacement space to a certain extent, reducing stress damage to the device caused by small changes in the ground, and improving the overall stability and durability of the device.

[0065] In the preferred embodiment, the connection between the fixed sliding plate 105 and the movable sliding plate 106 is a sliding connection, and the engagement between the spring buckle 107 and the limiting groove 108 is a clearance fit. The relative position of the fixed sliding plate 105 and the movable sliding plate 106 is adjusted by sliding, and the height is fixed by using the spring buckle 107 to engage with the corresponding limiting groove 108 to adapt to seedlings of different heights. The above settings can effectively improve the compatibility of the device with seedlings of different specifications and reduce the fixing difficulties caused by differences in seedling height. Moreover, the sliding and buckling operations are simple, and a single person can quickly complete the height adjustment, improving the work efficiency during seedling transplantation or maintenance.

[0066] In a preferred embodiment, the connecting rod 110 and the movable connecting rod 111 are connected by a sliding connection. A fixing pin is connected to the bottom of the movable connecting rod 111 and directly in front of the connecting frame 112. By sliding and adjusting the relative position of the connecting rod 110 and the movable connecting rod 111, and driving the fixing pin 104 into the ground, the stability of the connecting frame 112 is enhanced, thereby improving the overall protective effect of the device. The above settings not only ensure the device's flexibility and adaptability to different terrains, but also enable quick fixation to ensure structural stability. The sliding connection design facilitates adjustment according to actual needs, while the fixing pin provides reliable anchoring force, effectively resisting external impacts.

[0067] In a preferred embodiment, the connecting housing 201 is mounted on the side wall of the fixed sliding plate 105. A shaft retainer 204 is connected to the side wall of the connecting housing 201 and located on the cylindrical surface of the rotating screw 202. A rotating knob 203 is mounted on one end of the rotating screw 202. A limiting slide rod 206 is slidably mounted on the movable slider 205. Both ends of the limiting slide rod 206 are connected to the side wall of the connecting housing 201. A connecting rod 207 is mounted on the side wall of the movable slider 205. The other end of the connecting rod 207 is connected to the arc-shaped connecting plate 208 through a connecting seat. The above arrangement allows the rotating knob 203 to rotate, thereby driving the rotating screw 202 to rotate, which in turn drives the movable slider 205 to slide on the limiting slide rod 206. The connecting rod 207 drives the arc-shaped connecting plate 208 to move, realizing inter-structure linkage and meeting the needs of different working conditions.

[0068] In a preferred embodiment, the rotating screw 202 is connected to the connecting housing 201 via a bearing seat. The connection between the rotating screw 202 and the bearing seat is a rotatable connection, ensuring that the rotating screw 202 is stable and without deviation during rotation. This configuration enables the rotating screw 202 to accurately transmit power and reduce energy loss. At the same time, a drive motor is provided at one end of the rotating screw 202, which drives its rotation, thereby realizing the linear movement of the parts that cooperate with the screw and meeting the diverse working requirements of the equipment.

[0069] In a preferred embodiment, the rotating screw 202 is composed of a left-handed screw and a right-handed screw. The rotating screw 202 is connected to the movable slider 205 by a threaded connection. When the rotating screw 202 rotates, the two sets of movable sliders 205 move relative to or away from each other along the axis of the rotating screw 202 to adjust the spacing of the fixed clamp 210. This configuration can precisely control the spacing change of the fixed clamp 210 to meet the fixing requirements of items of different sizes. At the same time, the threaded connection ensures the stability and accuracy of the movement, making the entire adjustment process more reliable and effectively improving the flexibility and applicability of the equipment.

[0070] In a preferred embodiment, a connecting hole is provided on the movable slider 205 at the connection point with the limiting slide rod 206. The connection between the limiting slide rod 206 and the connecting hole is a sliding connection. The limiting slide rod 206 limits the movement direction of the movable slider 205 to prevent the movable slider 205 from deflecting as the rotating screw 202 rotates. The above settings ensure that the movable slider 205 only moves in a straight line along the axial direction of the limiting slide rod 206, thereby accurately driving the connected components to move, improving the stability and accuracy of the entire device operation, and ensuring the smooth realization of various functions in the solution.

[0071] In a preferred embodiment, a sliding groove is provided on the side wall of the connecting housing 201 at the connection point with the connecting rod 207. The connecting rod 207 is slidably connected to the sliding groove. The sliding groove provides guidance for the movement of the connecting rod 207, ensuring that the connecting rod 207 drives the arc-shaped connecting plate 208, the telescopic spring 209, and the fixed clamping plate 210 to move stably. This configuration allows the fixed clamping plate 210 to accurately clamp the target object, avoiding deviation or shaking. At the same time, the telescopic spring 209 can act as a buffer during movement, reducing impact force and further improving the stability and reliability of the entire connection structure.

[0072] In the preferred embodiment, the telescopic spring 209 has elastic deformation capability. When the fixing clamp 210 contacts the seedling, the telescopic spring 209 adaptively expands and contracts according to the diameter of the seedling, ensuring stable clamping of the seedling while avoiding damage to the seedling's surface due to excessive clamping force. The above settings can effectively improve the survival rate of seedlings during transplantation and reduce the risk of bacterial infection caused by mechanical damage. At the same time, the adaptive clamping structure reduces the cumbersomeness of manual adjustment, improves work efficiency, and provides reliable technical support for large-scale seedling planting.

[0073] In summary, this utility model provides a seedling protection device that effectively solves the existing technical problems of seedling protection in mountainous new energy project sites. Specifically, on the one hand, the site faces many problems: First, strong winds in mountainous areas easily cause seedlings to tilt, fall, and break branches, significantly reducing the survival rate of seedlings; second, wild animals and livestock such as cattle and sheep raised by villagers around the site easily graze on the green seedlings, damaging water conservation measures and impairing the effectiveness of water conservation measures in improving soil erosion and optimizing soil quality, thus making it difficult for the project to meet the water conservation acceptance standards, requiring repeated planting and increasing construction costs; third, existing protection methods (such as installing fences throughout the site and manual patrols to drive away the seedlings) are time-consuming, costly, and ineffective; fourth, existing seedling protection devices cannot adapt to the seedling protection needs of slopes with different angles and are difficult to flexibly adjust for seedlings of different heights and diameters.

[0074] On the other hand, this utility model has unique technical features. It comprehensively solves several complex and interconnected technical problems related to seedling protection in mountainous new energy project areas, including damage to seedlings caused by strong winds in mountainous areas, damage to seedlings by wild animals and livestock, poor effectiveness and high cost of existing protective methods, and poor adaptability of existing protective devices. This comprehensive and targeted problem-solving approach is rare in existing technologies. The device achieves effective protection for seedlings of different heights and diameters through the collaborative innovative design of the adjustable protective structure 1 and the adjustable clamping structure 2, while adapting to slope terrains with different angles. The newly added telescopic spring 3 provides cushioning to prevent breakage when the seedlings are subjected to external forces, and automatically adjusts the clamping force during seedling growth to ensure the optimal growth environment. The height and angle of the protective structure 1 are adjustable, and the spacing of the clamping structure 2 is adjustable and provides elastic clamping force. This all-round adjustable design is unique among similar seedling protection devices.

[0075] Furthermore, this utility model exhibits significant technical advantages. It breaks through the limitations of traditional seedling protection devices that focus solely on a single protective function, creatively integrating multiple functions such as wind resistance, animal grazing prevention, and adaptation to different terrains and seedling sizes into a complete seedling protection solution, greatly enhancing the protective effect and applicability. In the adjustable clamping structure 2 design, the linkage of components such as the rotating screw 4, the moving slider 5, and the connecting rod 6, combined with the elastic effect of the telescopic spring 3, achieves precise and elastic clamping of seedlings of different diameters. This complex design combining mechanical linkage and elastic adjustment is innovative, effectively solving the problem of improper clamping damaging seedlings or failing to provide protection. For the special environment of the mountainous new energy project site, an adjustable fixing structure 7 was creatively designed. Through the combination of the fixed connecting plate 8, the fixed connecting seat 9, the rotating support plate 10, the fixed sliding plate 11, and the moving sliding plate 12, the device achieves stable fixation on slopes or different terrains, as well as flexible adjustment of height and angle, providing an innovative solution for effective protection of seedlings in complex terrain. This utility model not only solves many problems existing in the current seedling protection device, but also significantly reduces the project construction cost and time cycle and improves construction efficiency through the optimized design of the overall device structure. This comprehensive technical contribution, which ranges from solving technical problems to improving economic benefits, has outstanding advantages among similar technologies.
