Description

Technical Field

[0001] The invention relates to the technical field of slope protection, in particular to an earth embankment slope protection unit and a slope protection device. Background Art

[0002] For road projects, the relatively poorly stable earth embankment slopes are prone to slope instability during the rainy season, and in severe cases, landslides, collapses, and other engineering quality problems that affect the stability of the roadbed may occur. In order to improve the stability of these slopes, slope protection bricks are usually laid on the surface of the slope, and then soil-protecting vegetation is planted in the center of the slope protection bricks. The plant slope protection can play a good role in protecting the slope.

[0003] According to the Chinese patent with the announcement number CN219951817U, a water conservancy slope structure is disclosed. In this utility model, a vegetation layer is laid inside the ecological slope protection bricks to prevent soil erosion. Garbage and sand are collected through the slope casting body and transported to the inside of the collection bucket through the conveying pipe, so as to realize the collection and storage of sand and garbage. The collection bucket can facilitate the cleaning staff to clear the garbage; The above technical solution prevents soil erosion by laying a vegetation layer inside the ecological slope protection bricks. However, after long-term use, the ecological slope protection bricks will become warped and loose, causing the slope protection bricks to fall off at local locations, which will easily cause local soil erosion during long-term use. At the same time, during dry periods with less rain, the vegetation on the slope will be difficult to survive due to dryness, which reduces the ability of the vegetation to protect the soil. For this reason, conventional watering methods are often used for irrigation, making it difficult to achieve directional irrigation of the vegetation in the ecological slope protection bricks. This conventional watering method is very likely to cause a waste of water resources. Summary of the invention

[0004] The object of the present invention is to provide an earth embankment slope protection unit and a slope protection device to solve the problems raised by the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an earth embankment slope protection unit, comprising a drainage channel, a track and a cross plate box, wherein the drainage channel is arranged in parallel between two water retaining plates, and the lower side of the water retaining plates is provided with slope protection bricks laid between the two drainage channels, wherein two side planes of the slope protection bricks are parallel to the drainage channel, and a water guide groove interspersed with the slope protection bricks is connected between the two drainage channels, The outer edge of the drainage channel abuts against a track, and support piles inserted into the slope soil layer are fixed at the bottom of the track.

The horizontal rod is inserted into the vertical arm of the bracket. Pressing wheels are connected to the middle of the narrow-distance frame and the opposite sides of the wide-distance frame respectively. The driving shaft, the driven shaft and the central axis of the turntable are sequentially connected through a synchronous component. An irrigation mechanism for watering the vegetation inside the slope protection bricks is also arranged on the cross-plate box.

[0006] Preferably, a runner is sleeved on the driving shaft close to the motor through a bearing. Teeth shorter than the width of the runner are arranged on the outer side of the runner. An inner cavity is opened on one side of the runner, and a ratchet tooth is connected in the inner cavity through a return spring. A ratchet ring fixed to the driving shaft is also arranged in the inner cavity of the runner.

[0007] Preferably, a transmission gear is connected to the inner side of the cross-plate box through a bearing seat. A swing arm is fixed on one side of the transmission gear. The swing arm is composed of a main arm rod and a sub-arm rod hinged together, and a ring is arranged at the end of the sub-arm rod of the swing arm.

[0008] Preferably, a sawtooth groove is opened on the outer peripheral side of the runner, and the sawtooth groove is a V-shaped notch composed of a short side and a long side. The short side of the sawtooth groove is perpendicular to the outer peripheral side of the runner. A rotating pin is installed on the side of the motor close to the runner, and a locking bar abutting against the sawtooth groove is sleeved on the rotating pin.

[0009] Preferably, a guiding frame is fixed between the motor and the inner wall of the cross-plate box. The irrigation mechanism includes a reciprocating plate sliding in the guiding frame. The end of the reciprocating plate is connected to the ring at the end of the sub-arm rod.

[0010] Preferably, a gas spring rod connected to the reciprocating plate is installed inside the cross-plate box. A rack is fixed on one side of the reciprocating plate. A hollow tooth sleeve meshing with the rack is rotatably connected to the middle of the cross-plate box. A rotating interface is movably connected to the upper end of the hollow tooth sleeve.

[0011] Preferably, a disc is installed on the lower side of the transverse plate box, and a water spraying box I and a water spraying box II are rotatably connected to the disc. The water inlet of the water spraying box I is fixed to the hollow gear sleeve, and steering gears are fixed to the upper ends of both the water spraying box I and the water spraying box II.

[0012] Preferably, the lower ends of the rotation centers of the water spraying box I and the water spraying box II are connected through a metal hose, and nozzles are obliquely connected to one side surface of each of the water spraying box I and the water spraying box II.

[0013] Preferably, a cover plate is hermetically installed on the upper side of the transverse plate box, and guide wheels abutted against the top surface of the drainage channel are movably connected to both ends of the cover plate.

[0014] A slope protection device, wherein the soil embankment slope protection unit is arranged on the slope surface of the embankment slope.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: for the soil embankment slope protection unit and the slope protection device, the transverse plate box, the driving mechanism, the extrusion mechanism and the irrigation mechanism are set to be linked. When the irrigation mechanism drives the nozzles on the water spraying box I and the water spraying box II to irrigate the vegetation at the center of the slope protection bricks in a counter-jet manner, the pressure wheels on the opposite sides of the wide-distance frame will synchronously extrude the two side edges of the slope protection bricks. When the irrigation mechanism drives the nozzles on the water spraying box I and the water spraying box II to irrigate the vegetation at the center of the slope protection bricks in a relative manner, the pressure wheel in the middle of the narrow-distance frame will synchronously extrude the abutting edges of two adjacent slope protection bricks, so as to ensure that the device has the effect of strengthening and compacting the slope protection bricks when irrigating the vegetation at the center of the slope protection bricks.

[0016] 1. For the soil embankment slope protection unit and the slope protection device, when the drive shaft rotates forward, it will synchronously drive the turntable to rotate forward. Thus, the turntable drives the horizontal rod to reciprocate through the connecting rod, so that the horizontal rod will reciprocally push and pull the bracket to drive the narrow-distance frames and the wide-distance frames on both sides to reciprocally rotate and swing, making the two groups of pressure wheels alternately roll and press the slope protection bricks on different horizontal lines of the slope surface, ensuring the effect of regularly compacting and preventing loosening of the slope protection bricks laid on the embankment slope, and further reducing soil erosion. At the same time, when the slope protection bricks laid on the embankment slope are warped, the reciprocally swinging bracket can drive the pressure wheels to knock the slope protection bricks, so that the slope protection bricks are re-pressed and laid flat. 2. When the driving mechanism drives the cross-plate box to move upward along the slope surface, the water spraying boxes 1 and 2 of the same group can irrigate the center position of the slope protection bricks directly below during the counter-flushing irrigation. In addition, the water spraying boxes 1 and 2 of the same group can irrigate the center positions of the slope protection bricks on the left and right sides directly below during the relative irrigation. This enables the water spraying boxes 1 and 2 of the irrigation mechanism to perform directional irrigation towards the centers of the stagger-distributed slope protection bricks during the reciprocating flipping, preventing excessive water from being poured on the slope protection bricks and causing water resource waste, and ensuring that the irrigation mechanism below the cross-plate box can perform directional irrigation of the vegetation at the center positions of the stagger-distributed slope protection bricks on the slope.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 - 10 , the present invention provides a technical solution: a slope protection unit for an earth embankment, including a drainage channel 1, a track 2 and a horizontal plate box 3. The drainage channel 1 is arranged in parallel between two water baffles 101. The lower side of the water baffle 101 is provided with slope protection bricks 102 laid between the two drainage channels 1. Two side planes of the slope protection bricks 102 are parallel to the drainage channel 1. A water guide groove 103 penetrating through the slope protection bricks 102 is communicated between the two drainage channels 1. The outer edge of the drainage channel 1 abuts against the track 2, and a support pile inserted into the slope soil layer is fixed at the bottom of the track 2. A horizontal plate box 3 is arranged between the two tracks 2. Driving mechanisms 4 are arranged at both ends of the horizontal plate box 3. The driving mechanism 4 includes a motor 401 installed inside the horizontal plate box 3. The output end of the motor 401 is connected to a driving shaft 402 that penetrates and extends out of one end of the horizontal plate box 3. A driven shaft 403 is also connected to one side of the horizontal plate box 3 close to the driving shaft 402. Toothed rollers meshing with the inner wall of the track 2 are fixed at the ends of the driving shaft 402 and the driven shaft 403. Below the lower side of one side of the horizontal plate box 3, an extrusion mechanism 5 is provided. The extrusion mechanism 5 includes a turntable 501 connected to one side of the horizontal plate box 3 through a bearing seat. A connecting rod 502 is movably connected to the side surface of the turntable 501. A horizontal rod 503 is docked between the two connecting rods 502. A mounting seat is fixed on the outer side of the horizontal plate box 3, and a bracket 504 is connected in the mounting seat. The bracket 504 is composed of a cross bar in the middle, a vertical arm in the middle of the cross bar, and narrow-distance frames and wide-distance frames on both sides of the cross bar. The horizontal rod 503 is inserted into the vertical arm of the bracket 504. Pressing wheels 505 are connected to the middle of the narrow-distance frame and the opposite sides of the wide-distance frame. The driving shaft 402, the driven shaft 403, and the central shaft of the turntable 501 are sequentially connected through a synchronous component 7. The synchronous component 7 is not limited to using a synchronous pulley and a synchronous belt for linkage or a sprocket and a chain for linkage. By connecting the driving shaft 402 and the driven shaft 403 through the synchronous component 7, the toothed rollers at the ends of the driving shaft 402 and the driven shaft 403 can be stably moved synchronously along the track 2. The synchronous component 7 connects the driving shaft 402 and the central shaft of the turntable 501, which facilitates the turntable 501 to drive the extrusion mechanism 5 to swing reciprocally when rotating; the pressing wheel 505 in the narrow-distance frame is located above the abutting position of two adjacent slope protection bricks 102, and the distance between the pressing wheels 505 on the opposite sides of the wide-distance frame matches the width of the slope protection brick 102.

[0021] During specific implementation, start the motor 401 in the horizontal plate box 3 to drive the driving shaft 402 to rotate forward. Through the synchronous component 7, drive the toothed rollers at the ends of the driving shaft 402 and the driven shaft 403 to move upward along the track 2, thereby driving the horizontal plate box 3 to move from the lower side to the upper side of the slope; when the driving shaft 402 rotates forward, it will synchronously drive the turntable 501 to rotate forward. Thus, the turntable 501 drives the horizontal rod 503 to reciprocally push and pull through the connecting rod 502, so that the horizontal rod 503 will reciprocally push and pull the vertical arm in the middle of the bracket 504. The vertical arm will drive the narrow-distance frames and wide-distance frames on both sides to rotate and swing reciprocally around the mounting seat on the outer side of the horizontal plate box 3 through the cross bar in the middle. Since the slope protection bricks 102 on the slope are regular hexagonal hollow brick structures, when laid, the outer planes of adjacent slope protection bricks 102 abut against each other. Therefore, the two groups of pressing wheels 505 will alternately roll and press the slope protection bricks 102 on different horizontal lines of the slope surface. When the pressing wheel 505 in the narrow-distance frame presses the vertical side of the first layer of slope protection bricks 102, the pressing wheel 505 on the opposite side of the wide-distance frame will press the vertical side of the second layer of slope protection bricks 102; similarly, when the horizontal plate box 3 continues to move upward along the slope, the narrow-distance frame and the wide-distance frame will drive the two groups of pressing wheels 505 to alternately press the slope protection bricks 102, ensuring that the slope protection bricks 102 laid on the embankment slope are regularly compacted and anti-loosened, thereby reducing soil erosion. At the same time, when the slope protection bricks 102 laid on the embankment slope are warped, the reciprocally swinging bracket 504 can drive the pressing wheel 505 to knock the slope protection bricks 102, so that the slope protection bricks 102 are re-pressed and laid flat.

[0022] Please refer toFigures 7 - 10 On one side of the drive shaft 402 close to the motor 401, a runner 404 is sleeved through a bearing. On the outer side of the runner 404, there are engaging teeth with a length less than the width of the runner 404. On one side of the runner 404, there is a cavity, and a ratchet tooth 405 is connected through a return spring in the cavity. A ratchet ring 406 fixed to the drive shaft 402 is also arranged in the cavity of the runner 404; The inner side of the horizontal plate box 3 is connected with a transmission gear 407 through a bearing seat. On one side of the transmission gear 407, a swing arm 408 is fixed. The swing arm 408 is composed of a main arm rod and a sub-arm rod hinged together, and a ring is arranged at the end of the sub-arm rod of the swing arm 408; On the outer peripheral side of the runner 404, a sawtooth groove 409 is arranged. The sawtooth groove 409 is a V-shaped notch composed of a short side and a long side, and the short side of the sawtooth groove 409 is perpendicular to the outer peripheral side of the runner 404. On one side of the motor 401 close to the runner 404, a rotating pin is installed, and a locking bar 410 abutted against the sawtooth groove 409 is sleeved on the rotating pin; A guide frame is fixed between the motor 401 and the inner wall of the horizontal plate box 3. An irrigation mechanism 6 for irrigating the vegetation inside the slope protection brick 102 is also arranged on the horizontal plate box 3. The irrigation mechanism 6 includes a reciprocating plate 601 sliding with the guide frame, and the end of the reciprocating plate 601 is connected with the ring at the end of the sub-arm rod.

[0023] During specific implementation, when the motor 401 drives the drive shaft 402 to rotate forward, the drive shaft 402 will drive the ratchet ring 406 to push the ratchet tooth 405, so that the ratchet tooth 405 drives the runner 404 to rotate accordingly. Thus, the runner 404 will squeeze the end of the locking bar 410 through the sawtooth groove 409 on the outer wall. Since the long side of the sawtooth groove 409 will squeeze the end of the locking bar 410 when the runner 404 rotates forward, the locking bar 410 will deflect around the rotating pin and move away from the runner 404. When the rotating runner 404 meshes with the transmission gear 407 through the engaging teeth on the outer wall, the transmission gear 407 will drive the main arm rod of the swing arm 408 to lift upward. Thus, the main arm rod of the swing arm 408 will pull the sub-arm rod, so that the sub-arm rod will pull the reciprocating plate 601 to slide along the guide frame through the ring at the end and compress the air spring rod 602; when the rotating runner 404 drives the engaging teeth to disengage from the transmission gear 407, the reciprocating plate 601 can be pushed reversely to reset through the reset of the air spring rod 602, and the reciprocating plate 601 will also straighten the swing arm 408; When the motor 401 drives the drive shaft 402 to reverse, the drive shaft 402 and the driven shaft 403 will move downward along the track 2. At this time, the reversing drive shaft 402 will drive the ratchet ring 406 to reverse and squeeze the ratchet teeth 405, causing the ratchet teeth 405 to swing and compress the return spring. At the same time, the short side of the serrated groove 409 of the runner 404 will abut against the end of the locking bar 410, thereby imposing a double restriction on the runner 404 to prevent the runner 404 from reversing. Therefore, the reverse rotation of the drive shaft 402 will not drive the runner 404 to rotate, and thus the reciprocating plate 601 will not generate a reciprocating motion, so that the cross-plate box 3 will not generate a reciprocating swing during the downward movement along the slope for alternating irrigation. Therefore, when the cross-plate box 3 moves downward along the slope, water supply is not carried out to it, which can avoid the erosion of the soil surface layer by water flow.

[0024] Please refer to Figures 2 - 8 , inside the cross-plate box 3, an air spring rod 602 connected to the reciprocating plate 601 is installed. One side of the reciprocating plate 601 is fixed with a rack 603. In the middle of the cross-plate box 3, a hollow gear sleeve 604 meshing with the rack 603 is rotatably connected. The upper end of the hollow gear sleeve 604 is movably connected with a rotary joint 605; A disc is installed on the lower side of the cross-plate box 3, and a water spraying box one 606 and a water spraying box two 607 are rotatably connected to the disc. The water inlet of the water spraying box one 606 is fixed to the hollow gear sleeve 604. Adjusting gears 608 are fixed to the upper ends of both the water spraying box one 606 and the water spraying box two 607.

[0025] The lower ends of the rotation centers of the water spraying box one 606 and the water spraying box two 607 are connected through a metal hose 609. Nozzles are obliquely connected to one side surface of both the water spraying box one 606 and the water spraying box two 607. A cover plate 301 is hermetically installed on the upper side of the cross-plate box 3. Guide wheels 302 abutting against the top surface of the drainage channel 1 are movably connected to both ends of the cover plate 301. The guide wheels 302 move on the top surface of the drainage channel 1, which can play a role in stabilizing the walking of the cross-plate box 3. The rotary joint 605 penetrates and is led out from the top of the cover plate 301. When the rotary joint 605 is connected to an external water supply pipe, the rotation of the hollow gear sleeve 604 will not drive the external water supply pipe to rotate together.

[0026] During specific implementation, when the slope protection bricks 102 are laid on the slope surface of the slope, two opposite corners of the slope protection bricks 102 are laid and placed vertically. At this time, the upper and lower adjacent layers of slope protection bricks 102 will show a cross-misaligned distribution; When the secondary arm rod of the swing arm 408 drives the reciprocating plate 601 to compress the gas spring rod 602, the rack 603 on one side of the reciprocating plate 601 will positively engage with the hollow gear sleeve 604, so that when the hollow gear sleeve 604 rotates, it can drive the water spraying tank one 606 under the disc to flip. Through the engagement between the two steering gears 608, the water spraying tank one 606 and the water spraying tank two 607 can be driven to flip in opposite directions at the same time. At the same time, the water supply pipeline is connected to the rotary interface 605 at the top of the cover plate 301, so that the water flows into the water spraying tank one 606 along the rotary interface 605 and the hollow gear sleeve 604. Then, the metal hose 609 is used to connect the water spraying tank one 606 and the water spraying tank two 607, so that the water fills the water spraying tank one 606 and the water spraying tank two 607, and the water sprays obliquely downward through the nozzles on the sides of the water spraying tank one 606 and the water spraying tank two 607, so that the sprayed water can irrigate the vegetation in the center of the slope protection brick 102; When the cross plate box 3 drives the water spraying tank one 606 and the water spraying tank two 607 to move above the center position of the slope protection brick 102, at this time, the rotating runner 404 drives the teeth and the transmission gear 407 to be out of contact with each other. Therefore, the gas spring rod 602 pushing the reciprocating plate 601 will ensure that the nozzles on the sides of the water spraying tank one 606 and the water spraying tank two 607 are arranged close to each other. Thus, when the two groups of nozzles spray water obliquely, a counter irrigation will be generated between the water spraying tank one 606 and the water spraying tank two 607, and thus the vegetation will not be concentratedly washed and the soil will not be loosened; When the cross plate box 3 drives the water spraying tank one 606 and the water spraying tank two 607 to move to the edge of the vertical side of the slope protection brick 102, at this time, the rotating runner 404 will drive the teeth to engage with the transmission gear 407. Therefore, the reciprocating plate 601 will compress the gas spring rod 602 and engage with the hollow gear sleeve 604 at the top of the water spraying tank one 606, so that the water spraying tank one 606 and the water spraying tank two 607 generate deflections in opposite directions. Thus, the nozzles on the sides of the water spraying tank one 606 and the water spraying tank two 607 are arranged away from each other, so that when the two groups of nozzles spray water obliquely, they will spray water obliquely on the opposite sides of the water spraying tank one 606 and the water spraying tank two 607, and thus can drive the nozzles on the opposite side to irrigate towards the center of the adjacent slope protection brick 102; Therefore, when the water spraying tank one 606 and the water spraying tank two 607 reciprocally flip, they can both conduct directional irrigation towards the centers of the slope protection bricks 102 distributed in a staggered manner, which can prevent excessive watering on the slope protection bricks 102 and cause waste of water resources. At the same time, when the same group of the water spraying tank one 606 and the water spraying tank two 607 conduct counter irrigation, they can irrigate the center position of the slope protection brick 102 directly below, and when the same group of the water spraying tank one 606 and the water spraying tank two 607 conduct relative irrigation, they can irrigate the center positions of the slope protection bricks 102 on the left and right sides directly below, so that the irrigation mechanism 6 below the cross plate box 3 can conduct directional irrigation of the vegetation at the center positions of the slope protection bricks 102 distributed in a staggered manner on the slope.

[0027] Please refer to Figure 1, a slope protection device, and the soil embankment slope protection unit is arranged on the slope surface of the embankment slope.

[0028] In summary, the soil embankment slope protection unit is arranged along the slope surface of the slope, so that the rainwater at the top of the embankment flows along the water baffle 101 into the drainage channel 1, and the water flow concentrates and flows downward along the drainage channel 1. At the same time, the soil layer on the slope surface is protected by the slope protection bricks 102, and the growth of the vegetation is strengthened by the slope protection bricks 102 laid on the slope surface. At the same time, the rainwater on the upper layer of the slope protection bricks 102 flows into the water guide groove 103 and then flows into the drainage channel 1 again for centralized discharge. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
