Description

Technical Field

[0001] The invention relates to the technical field of soil and water conservation, in particular to a vegetation slope protection soil and water conservation device. Background Art

[0002] In order to prevent soil erosion on the slopes, some vegetation slope protection structures are usually set up on the river bank slopes to achieve soil and water conservation on the slopes. Traditional vegetation slope protection technology usually involves digging some planting grooves on the slopes first, planting vegetation in the planting grooves, and the deep roots of the vegetation have an anchoring effect, while the shallow roots have a reinforcement effect on the soil and water, to achieve soil and water conservation on the slopes.

[0003] In the initial growth stage of vegetation, since the root system of vegetation is not yet developed, the vegetation's fixation effect on the soil is relatively weak. In heavy rainfall weather, it will be continuously washed away by rainwater above the slope, and there is a risk of the vegetation and surrounding soil being washed away from the planting trough.

[0004] In order to avoid the problem that vegetation and soil are easily washed away by rainwater in the initial growth stage, some vegetation slope protection structures will choose to add water retaining and protective structures around the vegetation to block the rainwater above and below the vegetation, which can effectively prevent vegetation and soil from being washed away by water flow impact. However, due to the existence of these shielding structures, the normal reception of sunlight by vegetation is affected, which is not conducive to the rapid growth of plants to achieve slope fixation. For example, the patent with publication number CN218204180U discloses an ecological slope protection support structure for water conservancy projects, which blocks the scouring of rainwater on the slope and prevents soil loss by setting a fixed baffle. However, its fixed baffle is upright and fixed on the slope, which has the problem of blocking the angle of sunlight, affecting the normal illumination process of plants and slowing down plant growth. For example, the patent with publication number CN221052515U discloses a water conservancy ecological slope protection structure, which prevents water from directly impacting vegetation by setting a water retaining cover above the vegetation placement groove. However, the water retaining cover is fixedly arranged around the upper half of the vegetation. On non-rainy days, the exposed water retaining cover will also block the sunlight shining on the vegetation at certain angles, causing certain interference to the normal photosynthesis of the vegetation.

[0025] Example

[0026] like Figures 1 to 4 As shown, an embodiment of the present invention provides a vegetation slope protection and soil and water conservation device, including a plurality of planting troughs 1 arranged along the slope surface, each planting trough 1 is provided with a shielding and protection mechanism, the shielding and protection mechanism includes a mounting tube 2, an annular baffle 3 and a telescopic structure; the mounting tube 2 is sleeved and fixed on the inner wall of the planting trough 1, and an annular mounting groove 21 is opened on the top of the mounting tube 2; the annular baffle 3 is slidably connected in the annular mounting groove 21; the telescopic structure includes: a water storage pipe 41, which is arranged parallel to the slope surface and is located below the planting barrel 2, one end of the water storage pipe 41 is connected to the top of the slope, and the other end of the water storage pipe 41 is connected to the top of the slope. It has a closed end; at least one slide rod 42 is arranged parallel to the central axis of the annular mounting groove 21, one end of the slide rod 42 is connected to the bottom of the annular baffle 3, and the other end of the slide rod 42 passes through the bottom of the planting barrel 2 and extends into the water storage pipe 41; a float 43 is arranged in the water storage pipe 41 and is connected to the other end of the slide rod 42. The float 43 is used to drive the annular baffle 3 to extend out of the annular mounting groove 21 after water is stored in the water storage pipe 41; a drainage component is connected to the other end of the water storage pipe 41, and is used to discharge rainwater in the water storage pipe 41 after the rain stops, so that the annular baffle 3 shrinks into the annular mounting groove 21.

[0027] In the present embodiment, on rainy days, the falling rainwater will be collected by the water storage pipe 41. As more and more rainwater is collected inside the water storage pipe 41, the water storage pipe 41 will be filled. When the buoyancy generated by the rainwater on the float 43 is greater than the gravity of the annular baffle 3 and the slide bar 42, the annular baffle 3 will be driven to extend out from the annular mounting groove 21. The annular mounting groove 21 protrudes from the planting barrel 2 to form a protection for the planting barrel 2, reducing the erosion of the soil and vegetation in the planting barrel 2 by rainwater from the upper slope. When the rainfall stops, the rainwater in the water storage pipe 41 is discharged through the drainage assembly, so that the annular baffle 3 shrinks back into the annular mounting groove 21 under the influence of its own gravity, avoiding blocking the sunlight from shining on the vegetation, so that the vegetation can grow normally.

[0028] Among them, the float 43 can adopt a buoyant structure such as a float or a float plate, and the other end of the slide rod 42 is connected to the top of the float or the float plate. In actual application, in order to ensure the buoyancy support strength, more slide rods 42 can be used to cooperate with the float 43 and connected to the bottom of the annular baffle 3.

[0029] In order to prevent external debris, such as mud or rainwater, from entering the annular mounting groove 21 and interfering with the movement of the annular baffle 3 during the lifting process of the annular baffle 3, a first sealing assembly is provided between the annular baffle 3 and the notch of the annular mounting groove 21. The first sealing assembly includes an inner sealing ring 51 and an outer sealing ring 52. The inner sealing ring 51 is connected to the inner groove wall of the annular mounting groove 21, and the outer sealing ring 52 is connected to the outer groove wall of the annular mounting groove 21. The annular baffle 3 is slidably connected between the inner sealing ring 51 and the outer sealing ring 52.

[0030] Preferably, the slide rod 42 is cylindrical, and a through hole is opened on the water storage pipe 41 for the slide rod 42 to pass through. A second sealing component is provided between the through hole and the slide rod 42. The second sealing component is a sealing ring, which is connected to the hole wall of the through hole and is slidingly sealed with the slide rod 42. Through the above arrangement, it is possible to achieve sealing between the slide rod 42 and the water storage pipe 41 and prevent rainwater accumulated inside the water storage pipe 41 from leaking.

[0031] Preferably, in order to limit the descending position of the annular baffle 3 when it is not blocking, and to prevent it from being completely retracted into the annular mounting groove 21 so that debris can enter the annular mounting groove 21, an annular limiting plate 6 is coaxially fixed on the top of the annular baffle 3, and the width of the annular limiting plate 6 is greater than the diameter of the annular mounting groove 21.

[0032] Specifically, the drainage assembly includes a water collecting trough 71, a water diversion pipe 72 and a drainage pipe 73; the water collecting trough 71 is opened at the top of the slope, and the water storage pipe 41 is connected to the bottom of the water collecting trough 71; one end of the water diversion pipe 72 is connected to the side wall of the water collecting trough 71, and the other end of the water diversion pipe 72 extends to the bottom of the slope, which is used to guide the rainwater overflowing from the water collecting trough 71 into the river; one end of the drainage pipe 73 is connected to the closed end of the water storage pipe 41, and the other end of the drainage pipe 73 is connected to the water diversion pipe 72. The diameter of the drainage pipe 73 is smaller than the diameter of the water storage pipe 41, and a permeable layer is provided in the drainage pipe 73.

[0033] In this embodiment, the drainage component is set up to discharge the rainwater collected in the water storage pipe 41 after the rainfall ends, and no buoyancy is provided to the float 43, thereby causing the annular mounting groove 21 to descend. The drainage principle is as follows: since the diameter of the drainage pipe 73 is smaller than the diameter of the water storage pipe 41, and a permeable layer is provided in the drainage pipe 73, the rainwater entering the water storage pipe 41 is much larger than the rainwater discharged, thereby ensuring that the rainwater will fill the water storage pipe 41 on rainy days to prop up the float 43. When the rainfall ends, no more rainwater enters the water storage pipe 41, and the drainage pipe 73 will slowly discharge the rainwater in the water storage pipe 41 into the water diversion pipe 72, and the water diversion pipe 72 will discharge it into the river, thereby realizing the process of lowering the annular mounting groove 21. At the same time, the set water diversion pipe 72 can also guide the rainwater that is filled with the water storage pipe 41 and overflows into the water collection tank 71 into the river on rainy days, thereby avoiding the problem of overflowing rainwater washing the slope again.

[0034] In another embodiment of the present invention, in order to discharge the accumulated water that falls into the inner side of the annular baffle 3 when the raised annular baffle 3 is used to block rainwater erosion and avoid flooding the vegetation, a plurality of groups of openings 31 are opened along the longitudinal direction of the lower half circle side wall of the annular baffle 3, and each group of openings 31 is arranged along the radial direction of the annular baffle 3, and a drainage structure is provided in each opening 31.

[0035] The drainage structure includes a water-permeable layer 81 and a water-absorbing layer 82. The opening 31 is provided with a first cavity 311, a second cavity 312 and a third cavity 313 from the inside to the outside. The water-permeable layer 81 is arranged in the first cavity 311, and the water-absorbing layer 82 is arranged in the second cavity 312. The water-permeable layer 81 can facilitate the water in the annular baffle 3 to penetrate and flow out, and prevent the loss of soil, while the water-absorbing layer 82 can quickly absorb the rainwater flowing out of the infiltrated water and discharge it through the third cavity 313.

[0036] Preferably, in order to facilitate drainage, the first cavity 311 and the third cavity 313 are both conical cavities, and the large diameter end of the first cavity 311 is arranged opposite to the inner groove wall of the annular mounting groove 21, and the large diameter end of the third cavity 313 is arranged opposite to the outer groove wall of the annular mounting groove 21.

[0037] In summary, the telescopic structure set up in the present invention can automatically control the extension of the annular baffle 3 on rainy days to provide shielding and protection for vegetation and planting soil, avoiding loss caused by excessive erosion by rainwater. After the rainfall ends, the baffle 3 is controlled to retract to avoid interfering with sunlight and reduce the impact on plant growth.

[0038] The above disclosures are only several preferred specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
