Description

Technical Field

[0001] This invention belongs to the technical field of riverbank protection devices, and particularly relates to a riverbank protection device for the Pearl River. Background Technology

[0002] The Pearl River (Chinese Pinyin: Zhujiang; English: Zhujiang River; Pearl River), formerly known as the Yue River, is the third largest river in China. Located in southern China, its annual runoff is second only to the Yangtze River. Originally referring to the section from Guangzhou to the mouth of the Dongjiang River, it was named after Haizhu Island in the river, and later used to refer to the entire river system. The Pearl River basin commonly refers to the vast basin of the Xijiang, Beijiang, Dongjiang rivers, and the Pearl River Delta. The Pearl River basin spans Yunnan, Guizhou, Guangdong, Guangxi, Jiangxi, and Hunan provinces. Located between 21°31′ and 26°29′ north latitude and 102°15′ and 115°53′ east longitude, it is formed by the confluence of the Dongjiang, Beijiang, and Xijiang rivers. The basin converges in a fan shape, but the various river systems are distributed in a dendritic pattern. The main stream is 2,214 kilometers long, and the drainage area is 453,600 square kilometers (including more than 10,000 square kilometers within Vietnam).

[0003] Chinese patent application number CN202111366275.3 discloses a Yellow River channel slope protection device, including a cylinder, a base plate fixedly connected to the bottom of the cylinder, a conical tip fixedly connected to the bottom of the base plate, three evenly distributed grooves along the radius of the upper end face of the base plate, a rod slidably connected in the grooves, a guide post extending upward from the upper end face of the rod, a through hole connected to the grooves in the cylinder, a drive plate above the base plate, an arc-shaped groove corresponding to the number of grooves on the side of the drive plate facing the base plate, each guide post extending into its corresponding arc-shaped groove, a drive rod inside the cylinder, the drive rod being fixedly connected to the center of the drive plate and rotatably connected to the base plate through the drive plate, so that rotating the drive rod drives the drive plate to rotate, and the arc-shaped groove guides the guide post to drive the rod to extend or retract into the through hole along the groove as the drive plate rotates. This solves the problem in the prior art that it is very inconvenient to replace damaged hexagonal hollow slope protection bricks and that it is easy to affect the adjacent slope protection bricks.

[0004] However, in the above technical solution, when fixing the device as a whole, the positioning legs are inserted into the gaps inside the adjacent slope protection bricks. But when replacing the damaged slope protection bricks, downward pressure is also required on the device as a whole. Without downward pressure, the device as a whole can easily move when the slope protection bricks are removed. Summary of the Invention

A second spring is sleeved on the surface of each first positioning rod. Pressure plates are fixedly connected to both sides of the pressing rod, and the bottom end of each pressure plate contacts the top end of the lifting block. Several second positioning posts are fixedly connected to both sides of the inner wall of the second cylinder, located between the first positioning rods. Each pair of second positioning posts forms a group, and a rectangular block is sleeved between each group of second positioning posts. One end of each rectangular block extends to the outside of the second cylinder. A third spring is sleeved on the surface of each second positioning post. A rotating block is rotatably connected to the bottom end of each rectangular block, and an extension block is inserted into the interior of each rotating block. Fixing grooves are provided on both sides of the top end of each ring.

[0009] As a preferred embodiment of the above technical solution, each of the extension blocks has a slot at its top and bottom sides, the diameter of each slot is the same as that of the extension block, and a locking block is inserted into both sides of each slot.

[0010] As a preferred embodiment of the above technical solution, a crossbar is rotatably connected between the opposing surfaces of the two cross plates, and a third gear is fixedly connected to both ends of the crossbar. A connecting plate is fixedly connected to the surface of the crossbar and between the two third gears. Several grooves are provided on the side of the pressing rod near the connecting plate.

[0015] The beneficial effects of this invention are as follows:

[0016] (1) By setting up a first cylinder, a second cylinder, a conical block, a stop block, a ring, and a rotating support mechanism, after the device is supported, the second cylinder is rotated so that its bottom end descends into the interior of other riverbank protection. The ring will contact the top of the riverbank protection. Pressing down the pressing rod causes the conical block to descend and press against the stop block. The stop block moves outward through the rectangular groove and contacts and presses against the outer wall of the riverbank protection, which can fix the second cylinder. By rotating the first gear, the second gear is rotated so that the bottom of the first cylinder descends to the bottom of the riverbank protection that needs to be replaced. By rotating the support mechanism, the bottom of the riverbank protection that needs to be replaced contacts its bottom end. Rotating the first gear in the opposite direction causes the first cylinder to rise and lifts the riverbank protection for replacement, which is beneficial for stable support when replacing the riverbank protection.

[0017] (2) By setting up lifting blocks, rectangular blocks and extension blocks, the pressing rod will also drive the pressure plate to descend. By squeezing, the lifting block descends and squeezes the rectangular block to move it outward. At this time, the rotating block is no longer blocked. It rotates 90 degrees by its own gravity and pulls the extension block outward so that its bottom end engages with the fixed groove. The locking block will engage with the locking groove to fix it, which is beneficial to give the ring downward pressure and enhance its stability.

[0018] (3) By setting a connecting plate and a groove, after supporting the ring, the rack is moved by pulling the push rod outward. While the rack moves, it drives the third gear to rotate the crossbar, so that the connecting plate rotates toward the groove and engages with one of the grooves, which helps to improve the overall stability of the second cylinder.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0030] Example

[0031] This invention provides a device for riverbank protection and treatment in the Pearl River, such as... Figures 1 to 4 As shown, it includes a platform 1 and a first cylindrical body 5. Several support frames 37 are rotatably connected to the bottom end of the platform 1, such as... Figure 9As shown, by opening several support frames 37, the entire device is supported on the Pearl River channel slope, making the distance between platform 1 and the Pearl River channel slope greater than the diameter of the slope. A first gear 2 is rotatably connected to one side of the top of platform 1, and a mounting block 3 is fixedly connected to the other side of the top of platform 1. A second gear 4 is rotatably connected to the top of mounting block 3. The first gear 2 and the second gear 4 mesh. Mounting holes are opened in the middle of platform 1, mounting block 3, and second gear 4. The first cylinder 5 is placed in the mounting hole. The first cylinder 5 and the second gear 4 are connected by a thread. By rotating the first gear 2, the second gear 4 rotates, thereby raising and lowering the first cylinder 5. Movable joints are opened on both sides of the top of platform 1. Each movable slot has a movable block 6 slidably connected to both ends. Each movable slot has a positioning mechanism (not shown in the figure) inside. Pressing the positioning mechanism allows the movable block 6 to move. Each movable block 6 has a second cylinder 7 threadedly connected inside. Each second cylinder 7 has a pressing rod 8 inserted inside. Each second cylinder 7 has a conical block 9 slidably connected inside, and the conical block 9 is fixedly mounted on the pressing rod 8. Pressing the pressing rod 8 downwards causes the conical block 9 to descend. Several abutment blocks 10 are slidably connected to the bottom of the inner wall of each second cylinder 7 and are located below the conical block 9. As the conical block 9 descends, it presses against the abutment blocks 10, causing the abutment blocks 10 to move outwards through the rectangular slot and contact the outer wall of the riverbank protection. Each second cylinder... The bottom of the outer wall of each cylinder 7 is provided with a rectangular groove. A ring 11 is slidably connected to the outer wall of each second cylinder 7 above the rectangular groove. Several first springs 12 are fixedly connected between each ring 11 and the outer wall of the second cylinder 7. A rotating support mechanism is provided inside the first cylinder 5, which can remove the riverbank revetment that needs to be replaced. A cleaning sleeve 36 is fixedly connected to the bottom of the platform 1, and the cleaning sleeve 36 is fitted onto the outer wall of the first cylinder 5. A magnet is provided on one side of the top of each support frame 37, and it is attracted to the bottom of the platform 1. The tops of the opposing surfaces of several abutments 10 are all curved surfaces, and several rubber pads are provided on the opposing surfaces of several abutments 10, and they are equidistant. The diameter of the abutments 10 is the same as that of the rectangular groove. During use, by... Open the support frame 37 to support the entire device on the Pearl River channel slope. Then, rotate the second cylinder 7 to lower its bottom end into the other channel slope. As the second cylinder 7 descends, the ring 11 contacts the top of the channel slope. Pressing down the pressing rod 8 lowers the conical block 9, which in turn presses against the abutment block 10. This causes the abutment block 10 to move outward through the rectangular groove and contact and press against the outer wall of the channel slope. The reaction force of the first spring 12 fixes the second cylinder 7 with the ring 11 and the abutment block 10, providing stable support for the device. Then, rotating the first gear 2 causes the second gear 4 to rotate, allowing the bottom of the first cylinder 5 to descend to the bottom of the channel slope that needs to be replaced.By rotating the support mechanism until the bottom of the riverbank revetment to be replaced contacts its bottom end, and then rotating the first gear 2 in the opposite direction, the first cylinder 5 rises, lifting the riverbank revetment for replacement. During the rise of the first cylinder 5, the cleaning sleeve 36 removes the silt adhering to its surface.

[0032] like Figure 5 As shown, the rotating support mechanism includes a Y-shaped plate 14 and an arc-shaped plate 15. A rotating rod 13 is inserted inside the first cylindrical body 5. The Y-shaped plate 14 is fixedly mounted on the rotating rod 13. Rotating the rotating rod 13 drives the Y-shaped plate 14 to rotate. Several arc-shaped grooves are connected to the bottom of the outer wall of the first cylindrical body 5. The arc-shaped plate 15 is rotatably mounted inside the first cylindrical body 5. One side of each arc-shaped plate 15 is in contact with the Y-shaped plate 14, and a first torsion spring is sleeved on the other side of each arc-shaped plate 15. A slider 16 is rotatably connected inside the first cylindrical body 5 and above the Y-shaped plate 14. The slider 16 is fixedly mounted on the rotating rod 13. A fixing block 17 is fixedly connected inside the first cylindrical body 5 and below the slider 16. A limiting block 18 is inserted into the top of the fixing block 17. Then, by rotating the rotating rod 13, the Y-shaped plate 14 is rotated, which causes the Y-shaped plate 14 to press and rotate multiple arc plates 15. One end of the arc plate 15 rotates to the bottom of the riverbank slope. While the rotating rod 13 is rotating, the slider 16 is also rotated. When the slider 16 is rotating, it presses the limiting block 18 and causes it to descend. After the arc plate 15 is fully unfolded, the rotating rod 13 is released. The limiting block 18 prevents the rotating rod 13 from returning to its original position. After the riverbank slope is lifted out, the rotating rod 13 is rotated in the opposite direction, which causes the Y-shaped plate 14 to return to its original position. The arc plate 15 is then returned to its original position by the first torsion spring, thus removing the lifted riverbank slope.

[0033] like Figures 6 to 8As shown, horizontal plates 19 are fixedly connected to both sides of the inner wall of the second cylinder 7. First positioning rods 20 are fixedly connected to both sides of the bottom end of each horizontal plate 19. There are two sets of first positioning rods 20, with a lifting block 21 sleeved between each set of first positioning rods 20. The lifting block 21 is limited by the first positioning rods 20. A second spring is sleeved on the surface of each first positioning rod 20. Pressure plates 22 are fixedly connected to both sides of the pressing rod 8. When the pressing rod 8 descends, it also drives the pressure plates 22 to descend, pressing the lifting block 21 and causing it to descend. The bottom end of each pressure plate 22 is connected to the lifting block 21. The tops of the first positioning rod 20 and the second positioning rod 21 are in contact with each other. Several second positioning posts 23 are fixedly connected to both sides of the inner wall of the second cylinder 7 between the first positioning rod 20. There are two groups of two second positioning posts 23. A rectangular block 24 is sleeved between each group of second positioning posts 23. When the lifting block 21 descends, it presses the rectangular block 24, causing it to move outward. One end of each rectangular block 24 extends to the outside of the second cylinder 7. A third spring is sleeved on the surface of each second positioning post 23. A rotating block 25 is rotatably connected to the bottom end of each rectangular block 24. An extension block 26 is inserted inside each rotating block 25. A fourth spring (not shown in the figure) is fixedly connected to one end of the rotating block 25. After the rectangular block 24 moves outward, the rotating block 25 is no longer blocked. At this time, it rotates 90 degrees by its own gravity, and then the extension block 26 inside the rotating block 25 is pulled outward so that its bottom end engages with the fixing groove. Fixing grooves are opened on both sides of the top of each ring 11, and locking grooves are opened on one side of the top and bottom of each extension block 26. The diameter of each fixing groove is the same as that of the extension block 26. Locking blocks are inserted on both sides of each fixing groove. The opposite sides of the two lifting blocks 21 are set as inclined surfaces, and the top of the opposite sides of the two rectangular blocks 24 are set as The inclined plane of the lifting block 21 has a larger diameter than that of the rectangular block 24. When the pressing rod 8 descends, it also drives the pressure plate 22 to descend. The pressure plate 22 squeezes the lifting block 21 to make it descend. When the lifting block 21 descends, it squeezes the rectangular block 24 to make it move outward. After the rectangular block 24 moves outward, the rotating block 25 is no longer blocked. At this time, it rotates 90 degrees by its own gravity, and then pulls the extension block 26 inside the rotating block 25 outward so that its bottom end engages with the fixing groove. At this time, the locking block will engage with the locking grooves on both sides of the extension block 26 to fix it, thereby giving the ring 11 a downward pressure and strengthening its stability.

[0034] like Figure 8As shown, a crossbar 27 is rotatably connected between the opposing surfaces of two horizontal plates 19. A third gear 28 is fixedly connected to both ends of the crossbar 27. A connecting plate 29 is fixedly connected to the surface of the crossbar 27 between the two third gears 28. Several grooves 30 are provided on the side of the pressing rod 8 near the connecting plate 29. Racks 31 are slidably connected to both sides of the top of the two horizontal plates 19. A fifth spring (not shown) is fixedly connected between one side of the rack 31 and the top of the horizontal plate 19. The rack 31 meshes with the third gear 28. The two racks 31 are located away from the connecting plate 29. A push rod 32 is fixedly connected between the ends. A short block is inserted into the top of the moving block 6. When the push rod 32 moves outward, it will squeeze the short block and make it descend. After the connecting plate 29 engages with the groove 30, the short block will no longer be squeezed and will return to its original position. At this time, it will block the push rod 32 and prevent it from returning to its original position. Then, by pulling the push rod 32 outward, the rack 31 will move. While the rack 31 moves, it will drive the third gear 28 to make the crossbar 27 rotate, thereby making the connecting plate 29 rotate toward the groove 30 and engage with one of the grooves 30, thus improving the stability of the second cylinder 7.

[0035] like Figure 5 As shown, a rotating blade 33 is fixedly connected to the surface of the rotating rod 13. A rubber ball 34 is provided on one side of the inner wall of the first cylinder 5 and below the rotating blade 33. A square plate 35 is rotatably connected on one side of the inner wall of the first cylinder 5 and between the blades of the rotating blade 33. A second torsion spring is sleeved on the middle of the square plate 35 near the end of the first cylinder 5. When the rotating rod 13 rotates, it will also drive the rotating blade 33 to rotate. When the rotating blade 33 rotates, it will drive the square plate 35 to rotate. The distance between the top of the square plate 35 and the rubber ball 34 is large and they will not contact each other. When the rotating rod 13 rotates in the opposite direction to reset, the rotating blade 33 will cause the square plate 35 to rotate in the opposite direction. At this time, the bottom end of the square plate 35 will contact the rubber ball 34 and squeeze it, so that the rubber ball 34 contacts and collides with the inner wall of the first cylinder 5, thereby causing the mud and sand adhering to the surface of the first cylinder 5 to fall off through vibration.

[0036] Working principle: In use, by opening the support frame 37, the entire device is supported on the Pearl River channel slope. Then, by rotating the second cylinder 7, its bottom end descends into the interior of the other channel slope. As the second cylinder 7 descends, the ring 11 contacts the top of the channel slope. By pressing down the pressing rod 8, the conical block 9 descends, pressing the abutment block 10. This causes the abutment block 10 to move outward through the rectangular groove and contact and press against the outer wall of the channel slope. The reaction force of the first spring 12 causes the ring 11 and the abutment block 10 to press against the second cylinder 7. The cylinder 7 is fixed to stably support the device. Then, by rotating the first gear 2, the second gear 4 is rotated, causing the bottom of the first cylinder 5 to descend to the bottom of the riverbank revetment that needs to be replaced. Then, by rotating the rotating rod 13, the Y-shaped plate 14 is rotated, causing the Y-shaped plate 14 to press against multiple arc plates 15 and rotate, so that one end of the arc plate 15 rotates to contact the bottom of the riverbank revetment. Then, the first gear 2 is rotated in the opposite direction again, causing the first cylinder 5 to rise and lift the riverbank revetment through the arc plates 15, thereby replacing it.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
