Description

Technical Field

[0001] This invention belongs to the field of ecological restoration technology, specifically relating to a simulated experimental sphere for slope vegetation restoration. Background Technology

[0002] Vegetation restoration is a key and challenging aspect of ecological reconstruction on unstable slopes, and species selection and its establishment mechanisms are fundamental to plant restoration. This paper summarizes the current problems in slope vegetation restoration research and practice, highlighting key issues such as planting density, species matching, slope vegetation degradation, insufficient community succession, and scarcity of available resources. Currently, in-situ planting and monitoring pose significant safety risks and randomness, limiting the monitoring of the vegetation establishment process. Existing environmental simulation chambers are mostly cuboid structures, requiring large equipment footprints and consuming considerable unused space. Summary of the Invention

[0003] Based on the problems mentioned in the background technology above, the present invention provides a slope vegetation restoration simulation test sphere to solve the problems that current in-situ planting and monitoring have significant safety risks and randomness, which limit vegetation construction, while the environmental simulation chamber occupies a large area and has a lot of extra space.

[0004] The technical solution adopted in this invention is as follows:

[0005] The slope vegetation restoration simulation test sphere includes a simulation chamber, a lighting component, a temperature control component, and a rainfall simulation component. A temperature and humidity detector is installed inside the simulation chamber. A base and a water storage tank are located below the simulation chamber. The simulation chamber comprises a lower hemisphere and an upper hemisphere hinged together. A handle is provided on the upper hemisphere for easy opening. A first mounting frame is provided on the water storage tank, and the lower hemisphere is hinged to the first mounting frame. A first geared rail is provided on the outer wall of the lower hemisphere, and a first drainage groove is formed on the first geared rail. A first stepper motor is located inside the water storage tank, and the first stepper motor is drivenly connected to the first geared rail. An inner hemisphere is hinged inside the sphere, and a landscaping panel is installed inside the inner hemisphere. The landscaping panel has a first reserved groove. The rotation axis of the inner hemisphere is perpendicular to the rotation axis of the lower hemisphere. A second geared rail is provided on the inner hemisphere, and a second drainage groove is provided on the second geared rail. A second stepper motor is installed on the outside of the lower hemisphere, and the second stepper motor is drivenly connected to the second geared rail. An annular air guide pipe is installed inside the upper hemisphere, and eight exhaust nozzles are connected at equal intervals on the annular air guide pipe. A solenoid valve is provided between each exhaust nozzle and the annular air guide pipe. The upper hemisphere is a transparent sphere, and the lighting components are located on the outside of the transparent sphere.

[0006] Based on the above technical solution, the present invention further improves upon the following:

[0007] Furthermore, a support ring matching the lower hemisphere is installed on the top of the water storage tank. Multiple first universal ball bearings are mounted on the support ring, contacting the lower hemisphere. A second pre-reserved groove is formed on the support ring, and a first toothed rail is located within the second pre-reserved groove. The support ring and the first universal ball bearings can support the weight of the lower hemisphere, reducing the burden on the first mounting frame and making it less prone to deformation.

[0008] Furthermore, the water storage tank is equipped with a water-proof cylinder, and a bearing ring is fitted onto the water-proof cylinder. A support is provided at the bottom of the water-proof cylinder, and the bottom of the water-proof cylinder is conical with a through hole at its center. Water accumulated in the lower hemisphere flows into the water-proof cylinder and then into the water storage tank. A large amount of water in the water storage tank can be isolated by the water-proof cylinder, making it difficult for the accumulated water to wash away the first and second stepper motors.

[0009] Furthermore, a second mounting bracket is provided inside the water-proof cylinder, on which a first worm gear and a first gear are mounted. The first gear meshes with a first gear rail. A first motor base is provided inside the water-proof cylinder, and a first stepper motor is mounted on the first motor base. A water-proof cover is installed outside the first stepper motor. A first worm gear is mounted on the shaft of the first stepper motor, and the first worm gear is connected to the first worm gear. The first stepper motor drives the first gear through the worm gear structure, which in turn drives the lower hemisphere to rotate, thus avoiding excessive load on the first stepper motor from the lower hemisphere.

[0010] Furthermore, a second motor mount is provided on the lower hemisphere, and the second stepper motor is mounted on the second motor mount. A third mounting bracket is provided on the inner wall of the lower hemisphere, and a second worm gear and a second gear are mounted on the third mounting bracket. The second gear meshes with a second gear rail. A second worm gear connected to the second worm gear is mounted on the shaft of the second stepper motor. A limit wheel is fixedly connected to the second gear, and the limit wheel is located in the second drainage groove. The second stepper motor drives the second gear through the worm gear structure, which in turn drives the inner hemisphere to rotate. This avoids excessive load on the second stepper motor from the inner hemisphere. At the same time, under the action of the limit wheel, the second gear rail can disengage from the second gear when the lower hemisphere is tilted.

[0011] Furthermore, the inner hemisphere is provided with multiple third drainage channels arranged in a ring. When the inner hemisphere is tilted, causing the second drainage channel to move away from the bottom of the inner hemisphere, water accumulated at the bottom of the inner hemisphere can flow out through the third drainage channels, thus preventing excessive water accumulation inside the inner hemisphere.

[0012] Furthermore, an annular filter is provided on the inner hemisphere port. The annular filter can seal the gap between the inner hemisphere and the lower hemisphere, preventing dead branches and leaves from falling into the gap and becoming difficult to clean.

[0013] Furthermore, the rainfall simulation component includes a water injection pipe and a T-shaped nozzle. The water injection pipe is fixedly installed on the upper hemisphere and is connected to an inlet pipe. The T-shaped nozzle includes a connecting pipe and a horizontal pipe. The connecting pipe is inserted into the water injection pipe and connected via a sealing cap and plastic bearing. The water injection pipe has a guide port, the outlet of which is smaller than the inner diameter of the connecting pipe. The horizontal pipe has two sets of atomizing nozzles, which are symmetrical about the center of the connecting pipe. When water is injected through the inlet pipe, the flowing water impacts the horizontal pipe and sprays out from the two sets of atomizing nozzles to simulate rainfall. Because the two sets of atomizing nozzles are symmetrical about the center of the connecting pipe, the reaction force during water spraying can drive the horizontal pipe to rotate, preventing the sprayed water from concentrating and excessively eroding the simulated landscape inside the inner hemisphere, thus affecting the rainfall simulation effect.

[0014] Furthermore, the base is provided with a sliding groove and an installation cavity. A second universal ball bearing is located at the bottom of the water storage tank within the sliding groove. A central column is located at the bottom of the water storage tank, and a guide hole is radially opened on the central column. A guide rod slides through the guide hole. A third stepper motor is installed in the installation cavity. A linkage rod is fixedly installed on the shaft of the third stepper motor, and the free end of the linkage rod is hinged to the guide rod. The third stepper motor drives the linkage rod to rotate, and the linkage rod drives the guide rod to slide within the guide hole. Simultaneously, the guide rod oscillates, causing the water storage tank to oscillate, simulating seismic shear waves.

[0015] Furthermore, a limiting ring is installed at the top of the mounting cavity, and the limiting ring is sleeved on the central column. The limiting ring restricts the water storage tank, preventing the second universal ball bearing from dislodging from the slide groove when the water storage tank is shaken.

[0016] The beneficial effects of this invention are:

[0017] 1. Construct a simulated rock slope on a landscaping board. Different plants can be planted on the rock slope. By controlling the tilt angles of the lower and inner hemispheres, the slope and height of the slope can be simulated. By studying the temperature, humidity, light conditions, and rainfall inside the experimental sphere, the effects of different planting and environmental conditions on the rock slope restoration can be investigated. The impact of different external forces on the slope ecology can be simulated, effectively solving the significant safety risks and randomness problems of in-situ planting and monitoring in the current slope ecological restoration process. No on-site monitoring is required, reducing safety risks and randomness.

[0018] 2. The experimental ball has a compact structure with little extra space, and the experimental area does not occupy other areas when adjusting the angle of the landscape panel, making it convenient to use;

[0019] 3. By opening the solenoid valves connected to exhaust nozzles in different directions, wind force in different directions can be generated. Attached Figure Description

Detailed Implementation

[0031] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] like Figures 1-4 As shown, the system includes a simulation chamber, a lighting component, a temperature control component, and a rainfall simulation component. A temperature and humidity detector is installed inside the simulation chamber. A base 2 and a water storage tank 1 are located below the simulation chamber. The simulation chamber includes a lower hemisphere 3 and an upper hemisphere 5 that are hinged together. A handle 50 is provided on the upper hemisphere 5 for easy opening. A first mounting bracket 14 is provided on the water storage tank 1, and the lower hemisphere 3 is hinged to the first mounting bracket 14. A first toothed rail 31 is provided on the outer wall of the lower hemisphere 3, and a first drainage groove 32 is formed on the first toothed rail 31. The water tank 1 is equipped with a first stepper motor 43, which is connected to the first gear rail 31. An inner hemisphere 6 is hinged inside the lower hemisphere 3. The inner hemisphere 6 has a connecting shaft 63 and is connected to the lower hemisphere 3 via the connecting shaft 63. A landscaping board 61 is installed inside the inner hemisphere 6. The landscaping board 61 is used to build a slope model. A first reserved groove 611 is provided on the landscaping board 61. The rotation axis of the inner hemisphere 6 is perpendicular to the rotation axis of the lower hemisphere 3. A second gear rail 6 is provided on the inner hemisphere 6. 4. A second drainage groove 65 is provided on the second gear rail 64. A second stepper motor 34 is installed on the outside of the lower hemisphere 3. The second stepper motor 34 is connected to the second gear rail 64. When the first stepper motor 43 is started, the tilt of the lower hemisphere 3 can be adjusted. When the second stepper motor 34 is started, the angle of the inner hemisphere 6 can be adjusted. By cooperating with the first stepper motor 43 and the second stepper motor 34, the tilt and tilt direction of the landscape board 61 can be adjusted to simulate different types of slopes. An annular air duct 51 is installed inside the upper hemisphere 5. Eight exhaust nozzles 52 are connected at equal intervals on the annular air duct 51. Solenoid valves are provided between the exhaust nozzles 52 and the annular air duct 51. Each exhaust nozzle 52 is located in one of the eight directions. Opening the corresponding solenoid valve can simulate different wind directions. At the same time, cold or hot air can be introduced through the annular air duct 51 to change the temperature inside the experimental sphere. The upper hemisphere 5 is a transparent sphere. The lighting components are located outside the transparent sphere. The interior of the experimental sphere can be illuminated by natural light or artificial lighting conditions can be provided by the lighting components.

[0033] like Figure 2 As shown, a bearing ring 11 matching the lower hemisphere 3 is installed on the top of the water tank 1. Multiple first universal balls are installed on the bearing ring 11. The first universal balls are in contact with the lower hemisphere 3. A second reserved groove 15 is opened on the bearing ring 11. The first toothed rail 31 is located in the second reserved groove 15. The bearing ring 11 and the first universal balls can bear the weight of the lower hemisphere 3, reducing the burden on the first mounting frame 14 and making the first mounting frame 14 less prone to deformation.

[0034] like Figure 2As shown, a water-proof cylinder 4 is provided inside the water storage tank 1. The bearing ring 11 is sleeved on the water-proof cylinder 4. A support 41 is provided at the bottom of the water-proof cylinder 4. The bottom of the water-proof cylinder 4 is conical and has a through hole 45 at the center. The water accumulated in the lower hemisphere 3 flows into the water-proof cylinder 4 and then into the water storage tank 1. A large amount of water in the water storage tank 1 can be isolated by the action of the water-proof cylinder 4, and the water is not easy to wash away the first stepper motor 43 and the second stepper motor 34.

[0035] like Figure 4 , Figure 5 As shown, a second mounting bracket 46 is provided inside the water-proof cylinder 4. A first turbine and a first gear 72 are mounted on the second mounting bracket 46. The first gear 72 meshes with the first gear rail 31. A first motor base 42 is provided inside the water-proof cylinder 4. A first stepper motor 43 is mounted on the first motor base 42. A water-proof cover 44 is installed outside the first stepper motor 43. A first worm gear 71 is mounted on the shaft of the first stepper motor 43. The first worm gear 71 is connected to the first turbine. The first stepper motor 43 drives the first gear 72 through the turbine-worm gear structure, which in turn drives the lower hemisphere 3 to rotate, thus avoiding excessive burden on the first stepper motor 43 caused by the lower hemisphere 3.

[0036] like Figure 4 , Figure 5 As shown, a second motor mount 33 is provided on the lower hemisphere 3, and a second stepper motor 34 is mounted on the second motor mount 33. A third mounting bracket is provided on the inner wall of the lower hemisphere 3, and a second worm gear 35 and a second gear 36 are mounted on the third mounting bracket. The second gear 36 meshes with a second gear rail 64. A second worm gear connected to the second worm gear 35 is mounted on the shaft of the second stepper motor 34. A limit wheel 361 is fixedly connected to the second gear 361, which is located inside the second drainage groove 65. The second stepper motor 34 drives the second gear 64 through the worm gear structure, which in turn drives the inner hemisphere 6 to rotate. This avoids the inner hemisphere 6 from putting too much burden on the second stepper motor 34. At the same time, under the action of the limit wheel 361, the second gear rail 64 can disengage from the second gear 36 when the lower hemisphere 3 is tilted.

[0037] like Figure 7 As shown, the inner hemisphere 6 has multiple third drainage channels 66 arranged in a ring. When the inner hemisphere 6 is tilted, causing the second drainage channel 65 to leave the bottom of the inner hemisphere 6, the water accumulated at the bottom of the inner hemisphere 6 can flow out through the third drainage channels 66, which can prevent excessive water accumulation inside the inner hemisphere 6.

[0038] like Figure 4 , Figure 7 As shown, an annular filter 62 is provided at the port of the inner hemisphere 6. The annular filter 62 can seal the gap between the inner hemisphere 6 and the lower hemisphere 3, preventing dead branches and leaves from falling into the gap between the inner hemisphere 6 and the lower hemisphere 3 and making them difficult to clean.

[0039] like Figure 4 , Figure 3 , Figure 8 As shown, the rainfall simulation component includes a water injection pipe 54 and a T-shaped nozzle. The water injection pipe 54 is fixedly installed on the upper hemisphere 5, and an inlet pipe 53 is connected to the water injection pipe 54. The T-shaped nozzle includes a connecting pipe 55 and a horizontal pipe 551. The connecting pipe 55 is inserted into the water injection pipe 54 and connected through a sealing cap plastic bearing 56. A water guide port 541 is provided inside the water injection pipe 54. The outlet of the water guide port 541 is smaller than the inner diameter of the connecting pipe 55. Two sets of atomizing spray nozzles 55 are provided on the horizontal pipe 551. 52. The two sets of atomizing nozzles 552 are symmetrical about the center of the connecting pipe 55. When water is injected through the inlet pipe 53, the water flows into the horizontal pipe 551 and sprays out from the two sets of atomizing nozzles 552 to simulate rainfall. Since the two sets of atomizing nozzles 552 are symmetrical about the center of the connecting pipe 55, the horizontal pipe 551 can be rotated under the reaction force when the water is sprayed, so as to avoid the concentrated water spraying over-washing of the simulated landscape inside the inner hemisphere 6 and affecting the rainfall simulation effect.

[0040] like Figure 4 , Figure 6 As shown, the base 2 is provided with a sliding groove 21 and a mounting cavity 22. The bottom of the water tank 1 is provided with a second universal ball bearing, which is located in the sliding groove 21. The bottom of the water tank 1 is provided with a central column 12, and a guide hole 13 is radially opened on the central column 12. A guide rod 25 slides through the guide hole 13. A third stepper motor 23 is installed in the mounting cavity 22. A linkage rod 24 is fixedly installed on the rotating shaft of the third stepper motor 23. The free end of the linkage rod 24 is hinged to the guide rod 25. The third stepper motor 23 drives the linkage rod 24 to rotate, and the linkage rod 24 drives the guide rod 25 to slide in the guide hole 13. At the same time, the guide rod 25 swings, causing the water tank 1 to swing to simulate seismic shear waves.

[0041] like Figure 4 As shown, a limiting ring 26 is installed at the top of the mounting cavity 22, and the limiting ring 26 is sleeved on the central column 12. The limiting ring 26 restricts the water storage tank 1 to prevent the second universal ball bearing from dislodging from the slide groove 21 when the water storage tank 1 is shaken.

[0042] During the simulation study, the tilt direction and tilt angle of the landscaping board 61 are first adjusted according to the target terrain. Then, soil and rock are placed on the landscaping board 61 to construct the landform of the target site. Then, corresponding plants are planted on the soil and rock according to the research content. Then, the temperature and humidity inside the experimental sphere are controlled, the lighting components are placed outside the experimental sphere, and the lighting time is set according to the climate of the simulated target site. When different wind directions need to be simulated, the solenoid valves on the exhaust nozzles 52 in the corresponding directions are activated to simulate the environmental climate of the surveyed area and observe the effect of rock slope restoration.

[0043] The above provides a detailed description of the slope vegetation restoration simulation test sphere provided by this invention. The specific embodiments are described only to aid in understanding the method and core ideas of this invention. It should be noted that those skilled in the art can make various improvements and modifications to this invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of this invention.
