[0002] With the intensification of global climate change and ecological environment problems, slope soil and water conservation and carbon cycle restoration have become important research directions in the current field of ecological restoration. As a common exposed ground surface in engineering construction, slopes are extremely vulnerable to rain erosion and wind erosion, resulting in soil erosion, difficult vegetation growth, and damage to the soil carbon pool, thereby exacerbating carbon emissions and ecological degradation.

[0003] The Chinese invention patent with the patent publication number CN116114496A, which was published on May 16, 2023, discloses a device for preventing soil erosion in riverbank vegetation restoration. When in use, the height of the external threaded tube with an interval of days is adjusted, and then the nutrient solution will flow out through the first liquid pouring holes at different heights. By using the hydrotropism of the main root system of the vegetation, the main root system is forced to grow downward towards the riverbank body, which is beneficial to strengthening the soil of the riverbank body and improving the production efficiency of the vegetation at the same time, but it cannot increase the photosensitive time of the vegetation.

Specific embodiments

[0033] As Figures 1-9 shown, the drip irrigation device for slope vegetation restoration in this embodiment includes a liquid storage barrel 1, a telescopic connecting pipe 2 fixed to the bottom of the liquid storage barrel 1, and a liquid outlet device 3 connected to the outlet end of the telescopic connecting pipe 2. The liquid outlet device 3 is used to convey water to the vegetation. A telescopic sleeve 4 is arranged at the top of the liquid storage barrel 1, and an automatic adjustment device 5 is arranged inside the liquid storage barrel 1 and the telescopic sleeve 4. The bottom of the automatic adjustment device 5 is fixed to the top of the telescopic connecting pipe 2; the reflector 7 is arranged on the outer wall of the telescopic sleeve 4 through a flipping device 6.

[0034] This application realizes the light tracking effect of the reflector 7 in a force-free manner. After filling the liquid storage barrel 1 with water, by using the cooperation of the device's own weight, the automatic adjustment device 5 and the liquid outlet device 3, the vegetation is irrigated regularly and at a fixed point, and the effect of photosynthesis is enhanced by the light reflected by the reflector 7. At the same time, the liquid outlet device 3 buried in the soil helps to reduce soil and water loss on the slope and plays a role in supporting and fixing the soil.

[0035] Furthermore, a liquid inlet head 11 is arranged on the side wall of the bottom of the liquid storage barrel 1.

[0036] Water or nutrient solution is added to the liquid storage barrel 1 through the liquid inlet head 11. If there is remaining or damaged liquid in the liquid storage barrel 1, it can also be discharged through the liquid inlet head 11.

[0037] Furthermore, an input hole 21 is opened on the side wall of the top of the telescopic connecting pipe 2, an output hole 22 is opened on the side wall of the bottom of the telescopic connecting pipe 2, the output hole 22 is connected to the liquid outlet device 3, and an insertion pipe 23 is fixed to the bottom end of the telescopic connecting pipe 2.

[0038] The liquid inside the liquid storage barrel 1 enters the telescopic connecting pipe 2 through the input hole 21, and then is input into the liquid discharging device 3 through the output hole 22 of the telescopic connecting pipe 2; the inserting pipe 23 facilitates the overall insertion of the device into the soil.

[0039] Further, the liquid discharging device 3 includes a liquid distributing pipe 31 and a solenoid valve 32 arranged in the middle of the liquid distributing pipe 31. The input end of the liquid distributing pipe 31 is communicated with the input hole 21, and the output end of the liquid distributing pipe 31 is arranged at the root of the vegetation.

[0040] The solenoid valve 32 is controlled by an external power supply. The outlets of different liquid distributing pipes 31 are arranged at the roots of different plants. When watering is needed, the solenoid valve 32 is opened, so that the liquid in the liquid storage barrel 1 flows into the liquid distributing pipe 31 through the telescopic connecting pipe 2 and then into the corresponding plant roots.

[0041] Further, the material of the liquid distributing pipe 31 is a degradable material.

[0042] After the liquid distributing pipe 31 is buried, it only needs to ensure that the waterway is unobstructed in the initial stage of vegetation growth. When the vegetation grows with developed roots and can grow independently, the service life of the liquid distributing pipe 31 is exhausted, and there is no need to turn over a large amount of soil to recover the underground liquid distributing pipe 31 when recycling the device.

[0043] Further, the telescopic sleeve 4 includes a fixed sleeve 41 and a threaded sleeve 42. The inner wall of the fixed sleeve 41 is provided with internal threads, and the inside of the fixed sleeve 41 is threadedly connected with the outer wall of the threaded sleeve 42.

[0044] According to the actual use requirements, the relative positions of the fixed sleeve 41 and the threaded sleeve 42 can be adjusted, thereby changing the length of the telescopic sleeve 4.

[0045] Further, the automatic adjustment device 5 includes a guide pipe 51, a piston 52 and a spring 53. The top end of the guide pipe 51 is arranged inside the threaded sleeve 42. The bottom of the guide pipe 51 penetrates through the fixed sleeve 41 and the liquid storage barrel 1 and is fixed to the piston 52; the bottom of the piston 52 is fixed to the top of the telescopic connecting pipe 2; a spring 53 is fixed between the top of the piston 52 and the inner wall of the top of the liquid storage barrel 1.

[0046] When water is supplied to the inside of the liquid storage barrel 1 through the liquid inlet head 11, during the rising process of the liquid level inside the liquid storage barrel 1, the piston 52 is driven to rise. The bottom of the piston 52 drives the telescopic connecting pipe 2 to elongate. While compressing the spring 53, the top of the piston 52 drives the guide pipe 51 to move upward, and the guide pipe 51 drives the flipping device 6 to move upward; when the solenoid valve 32 is opened to water the vegetation, during the descending process of the liquid level inside the liquid storage barrel 1, the piston 52 is driven to descend. The bottom of the piston 52 drives the telescopic connecting pipe 2 to contract. While the compressed spring 53 at the top of the piston 52 rebounds, it drives the guide pipe 51 to move downward, and the guide pipe 51 drives the flipping device 6 to move downward.

[0047] Further, the guiding tube 51 includes a plug rod 511, a socket 513 and a bolt 514. The bottom of the plug rod 511 extends into the interior of the socket 513, and the bottom of the inner cavity of the socket 513 is fixed to the bottom of the threaded sleeve 42. A plurality of jacks 512 are transversely formed in the middle of the plug rod 511, and the bolt 514 passes through and is fixed to the socket 513 through the jacks 512.

[0048] A plurality of jacks 512 are formed in the middle of the plug rod 511. When using this device, according to actual usage requirements, the bolt 514 can be passed through the jacks 512 at different positions and fixed, so as to adjust the overall length of the guiding tube 51, and better match the length of the guiding tube 51 with the length of the telescopic sleeve 4.

[0049] Further, the flipping device 6 includes a straight guide rail 61, a vertical steering gear 62, a connecting rod 63, a horizontal steering gear 64 and an arc guide rail 65. The bottom of the vertical steering gear 62 is fixed to the top of the plug rod 511. Straight guide rails 61 are longitudinally arranged on both sides of the vertical steering gear 62, and the straight guide rails 61 are fixed to the inner wall of the threaded sleeve 42. The connecting rod 63 is V-shaped. One end of the connecting rod 63 is connected to the vertical steering gear 62, and the other end of the connecting rod 63 is connected to the horizontal steering gear 64. The arc guide rail 65 is arranged in the middle of the horizontal steering gear 64. One end of the arc guide rail 65 is fixed to the outer periphery of the telescopic sleeve 4 through a fixed frame bar 67 and a first connecting sleeve 68 in sequence, and the other end of the arc guide rail 65 is fixed to the outer periphery of the telescopic sleeve 4 through a second connecting sleeve 69. The outer periphery of the horizontal steering gear 64 is fixed to the reflector 7. A strip-shaped hole 66 matching the connecting rod 63 is formed in the side wall of the telescopic sleeve 4.

[0050] This device does not perform real-time adjustment on the reflector 7, but uses timed adjustment. Usually, this device adds water (or nutrient solution) to the storage bucket 1 through the liquid inlet head 11 once a day, and opens the solenoid valve for watering once every 1 - 3 hours. When watering, the reflector 7 rotates synchronously, achieving the effect of light tracking. This device does not require high-precision flow control and uses non-continuous light tracking. Although the light tracking effect is not as accurate as that achieved by an electronic signal sensor, it is sufficient for the growth of outdoor slope vegetation. The position of the vertical steering gear 62 is controlled by the guiding tube 51. When the vertical steering gear 62 moves, it drives the connecting rod 63 to move, and the connecting rod 63 drives the horizontal steering gear 64 to move. Since the moving path of the horizontal steering gear 64 is restricted by the arc guide rail 65, the reflector 7 will be driven to rotate during the movement of the horizontal steering gear 64.

[0051] Taking the slope at 30° north latitude as an example:

[0052]

[0053] Through the above method, the effective irradiation time of the vegetation can be increased by about 2 - 4 hours per day, and the actual effect is affected by geographical location, season and weather. The analysis is as follows:

[0054]

[0055]

[0056] Furthermore, the vertical steering device 62 includes a turntable 621, a slider 622, a connecting block 623 and a rotating shaft 624. The two sides of the connecting block 623 are respectively fixed to a slider 622. A sliding groove matching the slider 622 is opened in the middle of the straight guide rail 61. The slider 622 slides through the sliding groove and cooperates with the straight guide rail 61. The bottom of the connecting block 623 is fixed to the top of the guide tube 51; one end of the rotating shaft 624 is rotatably connected to the connecting block 623, and the other end of the rotating shaft 624 is fixed to the turntable 621; the outer wall of the turntable 621 is fixed to the connecting rod 63.

[0057] The sliders 622 on both sides of the connecting block 623 are restricted by the straight guide rails 61 when moving. Through this structure, it can be ensured that the connecting block 623 will not deflect when moving. During the movement of the connecting rod 63, the turntable 621 rotates together with the connecting rod 63, and the connecting block 623 only moves longitudinally without rotating.

[0058] The method of use of the present invention is:

[0059] Normally, the device adds water (or nutrient solution) into the liquid storage barrel 1 once a day through the liquid inlet head 11, and opens the solenoid valve every 1-3 hours to water once. During watering, the reflector 7 rotates synchronously to achieve the effect of ray tracing.

[0060] According to the actual use requirements, the lengths of the telescopic sleeve 4 and the guide tube 51 are adjusted, and matching straight guide rails 61 and curved guide rails 65 are selected; after the overall assembly of the device is completed, water is supplied to the liquid storage barrel 1 through the liquid inlet head 11, and the piston 52 is driven to rise during the rising process of the liquid level inside the liquid storage barrel 1, and the bottom of the piston 52 drives the telescopic connecting tube 2 to extend, and the top of the piston 52 drives the guide tube 51 to move upward while compressing the spring 53, and the guide tube 51 drives the flip device 6 to move upward. When the liquid storage barrel 1 is filled with water (or nutrient solution), the vertical deflector 62 is in the highest position, and the reflector 7 is in the initial position. Since the position of the reflector 7 is jointly affected by the straight guide rail 61 and the curved guide rail 65, the initial position of the reflector 7 can be set to a tilted state according to the actual use requirements;

[0061] When watering the vegetation, the electromagnetic valve 32 is opened, and the liquid level inside the liquid storage barrel 1 drops. At the same time, under the combined action of the compression spring 53 and the self-weights of devices such as the guide tube 51 and the reflector 7, the piston 52 descends. The top of the piston 52 drives the guide tube 51 to move downward. The guide tube 51 drives the reflector 7 to move downward through the vertical steering device 62, the connecting rod 63, and the horizontal steering device 64 in sequence, so that the reflector 7 can cooperate with the change of the sun's altitude and be in different positions at different times to irradiate the vegetation for a longer time.

[0062] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
