Description

Technical Field

[0001] This invention belongs to the field of vegetation restoration technology, and specifically relates to a comprehensive device for vegetation restoration of bare soil at the base of power transmission line towers. Background Technology

[0002] The construction of power transmission lines inevitably alters the micro-topography of the construction area, damaging surface vegetation and disturbing soil layers. This is especially true in hilly areas, where construction constraints necessitate excavation of tower foundation areas and construction of temporary access roads, leading to severe soil erosion. Furthermore, the unique locations of soil erosion sites along power transmission lines make remediation difficult, exacerbating the problem and necessitating comprehensive management. Currently, the following problems exist in power transmission line construction: 1) disturbance and damage to the ground surface caused by large equipment during line laying; 2) inadequate measures for preventing and restoring soil erosion along construction roads; and 3) difficulty in restoring vegetation in tower foundation areas. Particularly in the tower foundation area, the loose surface of temporary excavated soil makes it susceptible to splash erosion under raindrop impact. During foundation excavation and temporary soil stockpiling, erosion primarily manifests as surface erosion and gully erosion. The construction surface is prone to surface and gully erosion under the influence of rainfall. After construction, rainwater is trapped by the towers, forming streams that flow down the base of the towers, eroding the foundation surface and forming fine or shallow trenches. In addition to water erosion, transmission line tower foundations are also subject to gravity erosion, wind erosion, and freeze-thaw erosion, exacerbating soil erosion problems.

[0003] Chinese patent application number CN202210191824.6 discloses a slope vegetation restoration device, including an irrigation mechanism, two water conveying mechanisms, and a fixing frame. The irrigation mechanism includes a support plate, with limit blocks and electromagnets fixedly installed on both sides of the upper surface of the support plate. A water storage tank is fixedly installed near the center of the upper surface of the support plate. Multiple water outlets are evenly opened on the front side of the water storage tank. Limit holes are opened on both sides of the water storage tank. An iron rod is movably installed between two of the limit holes. One end of the iron rod is fixedly connected to the electromagnet by a spring. Multiple water-blocking columns are evenly fixedly sleeved on the iron rod. A first-order elastic positioning pin is fixedly installed on both sides of the upper end of the inner wall of the water storage tank. The ends of the two first-order elastic positioning pins away from the water-blocking columns penetrate the water storage tank and are fixedly installed with insertion rods. This invention solves the problem of vegetation dying due to water shortage caused by dry slope soil. However, this invention can only supply water to the vegetation and cannot comprehensively manage the vegetation growth. Summary of the Invention

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1 This embodiment provides a comprehensive device for vegetation restoration of bare soil at the base of transmission line towers, such as... Figure 1 As shown, it includes a fixed frame 1 and an irrigation mechanism. The fixed frame 1 is provided with several planting frames 2, and protective vegetation is planted in the planting frames 2. Support columns 3 are provided at the four corners of the fixed frame 1. A control chip and a humidity sensor are provided on the inner side of one of the support columns 3, and the humidity sensor is electrically connected to the control chip. The irrigation mechanism includes two parallel lead screws 4, each with a motor 5 at one end and a bearing seat 6 at the other end. Both the motor 5 and the bearing seat 6 are mounted on a support column 3. The two motors 5 are electrically connected to a control chip. Each lead screw 4 has a slider 7, and a water tank 8 is mounted on each slider 7. Figure 2 As shown, the water tank 8 has a water inlet 9 on its side wall and several water outlets 10 at its bottom. like Figure 4 As shown, a cutting device is provided below the water tank 8; the cutting device includes a rotating blade 25, a chain drive sprocket assembly and two sets of transmission gear assemblies; the two sets of transmission gear assemblies are used to drive the chain drive sprocket assembly, and the chain drive sprocket assembly is used to drive the rotating blade 25 to rotate; like Figure 4-5 As shown, the transmission gear assembly includes gears 18 and racks 19 that mesh with them. The two gears 18 are respectively disposed at the bottom of the two sliders 7, and the two ends of the rack 19 are respectively connected to the two support columns 3. like Figure 4-7 As shown, the chain drive sprocket assembly includes two first sprockets 20, which are respectively disposed below two gears 18 and rotatably connected to the gears 18, as shown. Figure 6 As shown, several third connecting rods 21 are provided below the water tank 8. Each of the third connecting rods 21 is connected to a second sprocket 22. The two ends of the chain 23 are respectively engaged with two first sprockets 20 to drive the second sprockets 22 synchronously. Each second sprocket 22 is provided with a transmission shaft 24 below it. The end of the transmission shaft 24 is connected to the rotating blade 25. Figure 9 As shown, the chain 23 is provided with a baffle 26 on its side; like Figure 6-7 As shown, a fixed rod 11 is arranged perpendicular to the lead screw 4 inside the water tank 8. A cam-linkage device is arranged below the fixed rod 11. The cam-linkage device includes a first link 12, a second link 13, and a cam 14. The upper end of the first link 12 is connected to the fixed rod 11. The first link 12 and the second link 13 are coaxially arranged. The upper end of the second link 13 is sleeved outside the first link 12. A return spring 15 for resetting the second link 13 is sleeved on the first link 12. A piston 16 for closing the water outlet 10 is provided at the upper end of the second link 13, and a mating part 17 is connected to its lower end. The cam 14 is connected to the transmission shaft 24 and is arranged above the rotating blade 25. The cam 14 rotates synchronously with the rotating blade 25. The working surface of the cam 14 has an undulating structure for driving the second link 13 to move up and down. Figure 7 As shown, when the mating part 17 contacts the highest point of the cam 14, the piston 16 is located above the water outlet 10, as... Figure 8 As shown, when the mating part 17 contacts the lowest point of the cam 14, the piston 16 blocks the water outlet 10. When the water tank 8 is located at both ends of the fixing frame 1, the piston 16 just blocks the water outlet 10.

[0020] The working principle of this embodiment is as follows: Before use, the probe of the humidity sensor is inserted into the bare soil of the transmission line tower foundation, and water is supplied to the water tank 8 through the water inlet 9 via an external water pipe. When the humidity of the bare soil drops to the set value, the humidity sensor sends information to the control chip. After receiving the information, the control chip issues a command to the two motors 5, and the two motors 5 start working. The two sliders 7 drive the water tank 8 to move along the direction of the lead screw 4. At the same time, the two gears 18 set at the bottom of the slider 7 move along the rack 19 and drive the two first sprockets 20 to rotate, which in turn drives the chain 23 to start working. The chain 23 further drives the second sprocket 22 to rotate. The second sprocket 22 transmits power synchronously to the cam 14 and the rotating blades 25 through the transmission shaft 24. Several rotating blades 25 start working and can prune vegetation that exceeds the specified height, avoiding safety hazards caused by excessive vegetation on the transmission line tower foundation. Simultaneously, the mating part 17 contacts the working surface of the cam 14. As the cam 14 undulates, the mating part 17 moves up and down, driving the second connecting rod 13 and the piston 16 to move up and down. When the mating part 17 contacts the lowest point of the cam 14, several water outlets 10 of the water tank 8 are closed by the piston 16. When the mating part 17 contacts the highest point of the cam 14, several water outlets 10 of the water tank 8 are open, and water flows out of the water tank. The water flows downward onto the rotating blade 25, and the rotating blade 25 rotates to disperse the water flow, achieving uniform watering. When the moisture content of the bare soil reaches the specified value, the moisture sensor sends information to the control chip. After receiving the information, the control chip sends a command to the two motors 5, and the two motors 5 stop working. The two sliders 7 return to both ends of the fixed frame 1. At this time, the mating part 17 contacts the lowest point of the cam 14, the water outlets 10 are closed by the piston 16, the water tank stops flowing out of water, and the irrigation and pruning work is completed.

[0021] In summary, this invention achieves uniform irrigation of vegetation on the bare soil of transmission line tower foundations while comprehensively controlling the vegetation height through the cooperation of only two motors and mechanical structures. This not only maintains the vegetation but also saves manpower and electricity costs and avoids safety hazards caused by excessively tall vegetation on transmission line tower foundations.

[0022] In another embodiment of the invention, such as Figure 3 As shown, the side wall of the water tank 8 is also provided with a nutrient solution inlet 27. When the vegetation is not growing well, nutrient solution can be added to the nutrient solution inlet 27 and sprayed evenly using the water tank 8 to maintain the vegetation.

[0023] In another embodiment of the present invention, in the cam linkage device, the mating part 17 is a hemispherical or pulley structure, such as... Figure 7 As shown, the axis of the pulley structure is perpendicular to the axis of the cam 14, as... Figure 10 As shown, the mating part 17 is hemispherical.

[0024] In another embodiment of the present invention, a guide groove 28 is provided on the upper part of the rotating blade 25, such as... Figure 11 As shown.

[0025] In another embodiment of the invention, such as Figure 6 As shown, the third connecting rod 21 is disposed between the two water outlet holes 10, and the rotating blade 25 is disposed directly below the water outlet hole 10.

[0026] In another embodiment of the invention, such as Figure 2 As shown, the bottom of the fixing frame 1 is provided with a plug rod 29, which can be used to fix the device and make it more stable.

[0027] In another embodiment of the invention, such as Figure 2 As shown, a support member 30 is provided on the insertion rod 29. The support member 30 is used to support the fixing frame 1, so that there is a certain gap between the fixing frame 1 and the soil, thereby ensuring that the bare soil has full contact with the air and avoiding the rotting of the plant roots.

[0028] In another embodiment of the invention, such as Figure 1 As shown, the fixing frame 1 is provided with connecting components on both sides. The connecting components include two centrally symmetrical L-shaped connecting blocks 33. The two L-shaped connecting blocks 33 cooperate with each other to connect the two devices. One of the L-shaped connecting blocks 33 is provided with several planting holes 34. Protective vegetation is planted in the planting holes 34, which can further improve the stability of the connection between devices and between devices and bare soil of transmission line tower foundation.

[0029] In another embodiment of the invention, such as Figure 3 As shown, the bottom of the water tank 8, which is in contact with the slider 7, is provided with a protrusion 31, and both sliders 7 are provided with grooves 32. The grooves 32 and the protrusions 31 cooperate with each other to fix the water tank 8 and ensure the stability of the connection between the water tank 8 and the two sliders 7.

[0030] In another embodiment of the invention, such as Figure 2 , Figure 9 As shown, the lower part of the water tank 8 extends between the two sliders 7, which can further improve the stability of the water tank 8 installation.

[0031] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
