Description

Technical Field

[0001] This invention relates to the field of river vessel passage systems, and more specifically, to a vessel passage system used on a river. Background Technology

[0002] With the rapid development of river and sea transportation and the continuous increase in shipping volume in my country, the safe operation of ships is now the most important aspect. Along with the construction of bridges, when bridges are erected on the corresponding river surface, due to the limited height of the bridge and the limited distance between the bridge and the river surface, when large ships encounter them, the height of the ship is still higher than the height of the bridge after the ship floats on the river surface. At this time, it will cause the ship to be unable to pass under the bridge normally, affecting the normal transportation of ships.

[0003] To address these issues, a vessel passage system is typically installed at the bottom of the bridge. This system lowers the water level within the system after a vessel enters, causing the vessel to float at a lower height. Once the vessel's height is below the bridge's height, it can pass under the bridge. After passing, the water level within the system is adjusted to match the external river level, allowing the vessel to exit and achieve the effect of lowering the water level for passage under the bridge.

[0004] However, when using this type of ship passage system, the water injection operation and cessation are mainly achieved by opening and closing valves and transporting water through pipelines as ships pass under bridges. Since the valves are submerged in water, relying on valve opening and closing is problematic. Because the water contains many impurities, these impurities can easily become stuck in the valve core, preventing it from closing properly. Furthermore, impurities accelerate wear on the valve core. Finally, because the valves are submerged, replacing them is difficult when the seal fails, causing inconvenience to operators. Therefore, we propose a ship passage system for use on river surfaces. Summary of the Invention

[0005] The purpose of this invention is to provide a ship passage system for use on river surfaces to address the deficiencies mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A ship passage system for use on a river surface includes a main dam body connected to the outside world at both ends, the main dam body being arranged along the direction of river flow, and secondary dam bodies being arranged on both sides of the main dam body. A secondary water channel is arranged between the secondary dam bodies and the main dam body. A bottom leveling base is provided at the bottom of both the main dam body and the secondary dam bodies. From left to right, a first electric gate, a second electric gate, a third electric gate, and a fourth electric gate are arranged in sequence within the main dam body. A first waiting area, a low water level passage area, and a second waiting area are arranged in sequence between the first electric gate and the second electric gate, between the second electric gate and the third electric gate, and between the third electric gate and the fourth electric gate.

[0008] The auxiliary water tank is equipped with multiple water inlet components for introducing water into the first and second waiting areas. Each water inlet component includes multiple water inlet pipes fixedly installed on the side plate of the main dam body. Rust-proof pipes are fixedly installed at the ends of the multiple water inlet pipes, and outer sleeves are fixedly installed at the ends of the rust-proof pipes. The water inlet component also includes a U-shaped frame fixedly installed on the main dam body and the auxiliary dam body. Two symmetrical first hydraulic cylinders are fixedly installed on the top plate of the U-shaped frame. Water inlet covers are provided on the telescopic shafts of the two first hydraulic cylinders. A guide pipe is fixedly installed at the bottom end of the water inlet cover. The guide pipe is located inside the outer sleeve and is slidably connected to the outer sleeve.

[0009] As a preferred embodiment of the present invention, an arc-shaped mesh substrate is fixedly installed on the walls of both ends of the auxiliary water tank. The arc-shaped mesh substrate has a mesh-like plate structure and is used to block impurities from entering the auxiliary water tank.

[0010] As a preferred embodiment of the present invention, an impurity scraping assembly is provided at the arc-shaped mesh substrate. The impurity scraping assembly includes a support base fixedly installed on the top surface of the arc-shaped mesh substrate. A drive motor is fixedly installed at the center of the top surface of the support base. A vertically arranged long shaft is fixedly installed at the end of the output shaft of the drive motor. Two symmetrical scraper blades are fixedly installed on the long shaft. The side of the scraper blades abuts against the arc-shaped mesh substrate. The scraper blades are provided with exposure holes for water flow. The cross-section of the arc-shaped mesh substrate is less than half an annular shape. This allows the impurities on the arc-shaped mesh substrate to be pushed to one side of the water flow and washed away by the water flow by the rotation of the scraper blades, thereby achieving the effect of cleaning the impurities on the arc-shaped mesh substrate.

[0011] As a preferred embodiment of the present invention, drainage mechanisms are provided on both sides of the main dam body. Each drainage mechanism includes a drainage pipe, with the outlet end of the drainage pipe located downstream of the low-lying area of ​​the river surface. Multiple equally spaced guide pipes are fixedly installed on the drainage pipe. The guide pipes are fixedly installed on the main dam body and connected to the corresponding first waiting area, the low-water-level passage area, and the second waiting area. Solenoid valves are fixedly installed on the guide pipes to enable rapid drainage operations without the use of pumps, thereby saving energy.

[0012] As a preferred embodiment of the present invention, a plurality of pump body plates arranged at equal intervals are fixedly installed between the main dam body and the secondary dam body. A drainage assembly is provided on the pump body plates. The drainage assembly includes a suction pump fixedly installed on the pump body plates. A suction pipe is fixedly installed at the inlet end of the suction pump. A plurality of vertical pipes arranged at equal intervals are fixedly installed on the suction pipe. The vertical pipes are placed inside the main dam body. An external discharge pipe is fixedly installed at the outlet end of the suction pump. The end of the external discharge pipe extends into the secondary water tank, thereby enabling drainage operations to be performed using the suction pump, improving drainage efficiency, and making the drainage speed faster.

[0013] As a preferred embodiment of the present invention, pipe arrangement grooves are provided on the inner surface of the base on both the left and right sides of the main dam body. A mesh box is fixedly installed on the bottom wall of the pipe arrangement groove. The vertical pipe is placed at the location of the pipe arrangement groove, and the bottom end of the vertical pipe is inserted into the mesh box. This achieves the purpose of using the mesh box to block the entry of impurities and avoids excessive impurities from entering the suction pump and affecting the normal operation of the suction pump.

[0014] As a preferred embodiment of the present invention, multiple inner wall anti-collision components are arranged linearly and at equal intervals on the base of both sides of the main dam body. Each inner wall anti-collision component includes a protruding column fixedly installed on the top surface of the main dam body. An anti-detachment disc is fixedly installed at the top of the protruding column. A binding rope is tied to the protruding column, and a rubber tire is provided at the bottom end of the binding rope. The rubber tire abuts against the inner side of the main dam body. By using the discarded rubber tire, the two sides of the main dam body can be protected, preventing ships from colliding with the main dam body and causing damage.

[0015] As a preferred embodiment of the present invention, a guide plate is fixedly installed between the inner walls of the left and right sides of the U-shaped frame, and a guide hole is provided at the center of the guide plate. The guide tube passes through the guide hole and is slidably connected to the guide hole, thereby guiding the up and down movement of the guide tube.

[0016] As a preferred embodiment of the present invention, a side plate is fixedly installed on the side of the U-shaped frame, and a support leg is fixedly installed between the side plate and the top surface of the main dam body and the secondary dam body. A ladder is fixedly installed between the support leg and the U-shaped frame, so that workers can climb the ladder to the side plate to perform corresponding maintenance and other processing operations.

[0017] As a preferred embodiment of the present invention, a limiting plate is fixedly installed at the end of the telescopic shaft of the first hydraulic cylinder, and protruding plates are fixedly installed on both the left and right sides of the water inlet cover. The protruding plates are fixedly installed on the bottom surface of the limiting plate. A first flange is fixedly installed at the bottom end of the guide tube, and a second flange is fixedly installed on the bottom surface of the first flange. The first flange and the second flange are both located inside the outer sleeve and are slidably connected to the outer sleeve. A sealing ring is fixedly installed between the first flange and the second flange. The sealing ring and the outer sleeve are interference-fitted. A flared sleeve is fixedly installed at the top end of the outer sleeve. The inner diameter of the flared sleeve decreases sequentially from top to bottom, which facilitates the use of the sealing ring to improve the sealing effect and makes leakage less likely.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention, through the setting of a first electric gate, a second electric gate, a third electric gate, a fourth electric gate, a first waiting area, a low-water passage area, and a second waiting area, enables ships to lower the water level in the first or second waiting area after they have traveled there. After the water level has been lowered, the ship then travels to the low-water passage area, where the water level is further lowered, ensuring that the ship can pass under the bridge. After passing the bridge, water is added to the corresponding first or second waiting area until it is level with the river surface, and the ship then sails outward, achieving the effect of lowering the water level to pass under the bridge.

[0020] 2. This invention, through its water inlet assembly, ensures that during use, as the first hydraulic cylinder operates, the water inlet cover is inserted into the liquid surface. At this time, the rainwater can flow along the water inlet cover and the water inlet pipe into the corresponding first or second waiting area, raising the water level to be parallel to the river surface. As the water inlet cover moves upward and reaches above the liquid surface, water flow cannot enter the water inlet pipe, achieving water cut-off. In addition, no valve is needed during this process, and the sealing ring improves the sealing effect, making leakage less likely. Finally, when the first hydraulic cylinder moves and drives the sealing ring to the outside of the outer sleeve, it is easy to replace the sealing ring, making it convenient to use and achieving the effects of easy water inlet operation and easy replacement of the sealing ring.

[0021] 3. The present invention, through the setting of the arc-shaped mesh substrate, ensures that the water flow can enter the auxiliary water tank normally, while the arc-shaped mesh substrate can block the entry of impurities. In addition, through the setting of the impurity scraping component, the drive motor can be used to drive the scraper to rotate, thereby realizing the cleaning operation of impurities on the surface of the arc-shaped mesh substrate, which is convenient to use.

[0022] 4. The present invention, through the drainage components and drainage mechanism, can open the solenoid valve to perform drainage operation, and at the same time can use the suction pump to achieve drainage operation, making drainage more timely and improving drainage efficiency.

[0023] 5. The present invention, through the inner wall anti-collision component, can use discarded rubber tires to protect the inner wall of the main dam, preventing ships from directly hitting the main dam and causing damage to the main dam. Attached Figure Description

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0043] Please see Figures 1-9 This invention provides a technical solution: a ship passage system for use on a river surface, comprising a main dam body 1 connected to the outside at both ends, the main dam body 1 being arranged along the direction of river flow, secondary dam bodies 10 being arranged on both sides of the main dam body 1, a secondary water channel 11 being arranged between the secondary dam bodies 10 and the main dam body 1, and bottom leveling bases 12 being provided at the bottom of both the main dam body 1 and the secondary dam bodies 10, and a first electric gate 13, a second electric gate 131, a third electric gate 132, and a fourth electric gate 133 being arranged sequentially from left to right inside the main dam body 1, the first electric gate 13... A first waiting area 14, a low-water passage area 141, and a second waiting area 142 are sequentially arranged between the second electric gate 131, between the second electric gate 131 and the third electric gate 132, and between the third electric gate 132 and the fourth electric gate 133. This allows ships to first travel to the first waiting area 14 or the second waiting area 142. As the water level in the first waiting area 14 or the second waiting area 142 decreases, the ship then travels to the low-water passage area 141. When the water level in the low-water passage area 141 decreases to a level where the ship can pass under the bridge, the ship then passes under the bridge.

[0044] Specifically, the auxiliary water tank 11 is equipped with multiple water inlet components 5 for introducing water into the first waiting area 14 and the second waiting area 142. Each water inlet component 5 includes multiple water inlet pipes 57 fixedly installed on the side plate of the main dam body 1. The water inlet pipes 57 are connected to the interior of the corresponding first waiting area 14 and second waiting area 142. Rust-proof pipes 56 are fixedly installed at the ends of the multiple water inlet pipes 57, and outer sleeves 55 are fixedly installed at the ends of the rust-proof pipes 56. The outer sleeves 55 are vertically arranged and submerged in the water. The water inlet components 5 also include... The system includes a U-shaped frame 50 fixedly installed on the main dam body 1 and the secondary dam body 10. Two symmetrical first hydraulic cylinders 52 are fixedly installed on the top plate of the U-shaped frame 50. Water inlet covers 531 are provided on the telescopic shafts of the two first hydraulic cylinders 52. A guide pipe 54 is fixedly installed at the bottom end of the water inlet cover 531. The guide pipe 54 is located inside the outer sleeve 55 and is slidably connected to the outer sleeve 55, so that water can be introduced by inserting the water inlet cover 531 into the liquid surface. When the water inlet cover 531 moves upward to the outside of the liquid surface, it can prevent water from entering.

[0045] In this embodiment, arc-shaped mesh substrates 111 are fixedly installed on the walls of both ends of the auxiliary water tank 11. The arc-shaped mesh substrates 111 have a mesh-like plate structure and are used to prevent impurities from entering the auxiliary water tank 11. An impurity scraping component 2 is provided at the arc-shaped mesh substrate 111. The impurity scraping component 2 includes a support base 20 fixedly installed on the top surface of the arc-shaped mesh substrate 111. The support base 20 is fixedly installed on both the main dam body 1 and the auxiliary dam body 10 to ensure that the overall structure is more robust and stable. A drive motor 21 is fixedly installed at the center of the top surface of the support base 20. A vertically arranged long shaft 22 is fixedly installed at the end of the output shaft of the drive motor 21. Two symmetrical scraper plates 23 are fixedly installed on the long shaft 22. The side of the scraper plate 23 abuts against the arc-shaped mesh substrate 111. The scraper plate 23 is provided with an exposure hole 24 for water flow. The cross section of the arc-shaped mesh substrate 111 is less than half an annular shape. The rotation of the scraper plate 23 pushes the impurities on the arc-shaped mesh substrate 111 to one side of the water flow and washes them away with the water flow, thus achieving the effect of cleaning the impurities on the arc-shaped mesh substrate 111 and making it convenient to use.

[0046] Specifically, drainage mechanisms 3 are installed on both sides of the main dam body 1. Each drainage mechanism 3 includes a drainage pipe 30. The outlet end of the drainage pipe 30 is located downstream of the low-lying area on the river surface. Multiple equally spaced guide pipes 31 are fixedly installed on the drainage pipe 30. The guide pipes 31 are fixedly installed on the main dam body 1 and connected to the corresponding first waiting area 14, low water level passage area 141, and second waiting area 142, so that the water in the first waiting area 14, the low water level passage area 141, or the second waiting area 142 can be discharged normally outward along the drainage pipe 30. A solenoid valve 32 is fixedly installed on the guide pipe 31. The solenoid valve 32 is used to control the opening and closing of the pipe, so as to realize rapid drainage operation without the use of the pump body, which helps to save energy.

[0047] Furthermore, multiple pump body plates 15 arranged at equal intervals are fixedly installed between the main dam body 1 and the secondary dam body 10. A drainage assembly 6 is installed on each pump body plate 15. The drainage assembly 6 includes a suction pump 60 fixedly installed on the pump body plate 15. A suction pipe 61 is fixedly installed at the inlet end of the suction pump 60. Multiple vertical pipes 62 arranged at equal intervals are fixedly installed on the suction pipe 61. The vertical pipes 62 are placed inside the main dam body 1. Specifically, the vertical pipes 62 are inserted into the corresponding first waiting area 14, low water level passage area 141, and second waiting area 142. An external discharge pipe 63 is fixedly installed at the outlet end of the suction pump 60, and the end of the external discharge pipe 63 extends into… Within the auxiliary water tank 11, a suction pump 60 is used for drainage operations, improving drainage efficiency and increasing drainage speed. Specifically, pipe arrangement grooves 16 are provided on the inner surfaces of the base on both the left and right sides of the main dam body 1. A mesh box 161 is fixedly installed on the bottom wall of the pipe arrangement groove 16. The vertical pipe 62 is placed at the location of the pipe arrangement groove 16, thus hiding and protecting the vertical pipe 62 inside the main dam body 1 to avoid damage from impact. The bottom end of the vertical pipe 62 is inserted into the mesh box 161, which blocks the entry of impurities, preventing excessive impurities from entering the suction pump 60 and affecting its normal operation.

[0048] In addition, multiple inner wall anti-collision components 4 are arranged linearly and at equal intervals on the base of the left and right sides of the main dam body 1. The inner wall anti-collision components 4 include protruding columns 40 fixedly installed on the top surface of the main dam body 1. Anti-detachment discs 41 are fixedly installed on the top of the protruding columns 40. Tie ropes 42 are tied to the protruding columns 40. The anti-detachment discs 41 can prevent the ties 42 from falling off the protruding columns 40. Rubber tires 43 are installed at the bottom of the ties 42. The rubber tires 43 are pressed against the inner side of the main dam body 1. The scrapped rubber tires 43 can protect the two sides of the main dam body 1 and prevent ships from colliding with the main dam body 1 and causing damage.

[0049] It is worth noting that guide plates 501 are fixedly installed between the inner walls of the left and right sides of the U-shaped frame 50. A guide hole 502 is provided at the center of the guide plate 501. The guide tube 54 passes through the guide hole 502 and is slidably connected to the guide hole 502, which guides the up and down movement of the guide tube 54. Side plates 51 are fixedly installed on the side of the U-shaped frame 50. Support legs 511 are fixedly installed between the side plates 51 and the top surfaces of the main dam body 1 and the secondary dam body 10. A ladder 512 is fixedly installed between the support legs 511 and the U-shaped frame 50, which facilitates workers to climb to the side plate 51 for corresponding maintenance and other operations.

[0050] It is worth noting that a limiting plate 521 is fixedly installed at the end of the telescopic shaft of the first hydraulic cylinder 52, and protruding plates 53 are fixedly installed on both the left and right sides of the water inlet cover 531. The protruding plates 53 are fixedly installed on the bottom surface of the limiting plate 521 by multiple fastening bolts, which facilitates the fixed installation operation; a first flange 541 is fixedly installed at the bottom end of the guide tube 54, and a second flange 543 is fixedly installed on the bottom surface of the first flange 541. Both the first flange 541 and the second flange 543 are located inside the outer sleeve 55 and are connected to the outer sleeve. The pipes 55 are slidably connected. A sealing ring 542 is fixedly installed between the first flange 541 and the second flange 543. The sealing ring 542 and the outer sleeve 55 are interference-fitted, which makes it easier to improve the sealing effect and prevent leakage. A flared sleeve 551 is fixedly installed at the top of the outer sleeve 55. The inner diameter of the flared sleeve 551 decreases from top to bottom, which makes it easier for the first flange 541, the second flange 543 and the sealing ring 542 to be inserted into the outer sleeve 55 through the flared sleeve 551.

[0051] In this embodiment, the bottom wall of the main dam body 1 is equipped with multiple mud and sand pushing components 7 for pushing out mud and sand. The mud and sand pushing components 7 are used to push out the mud and sand at the bottom of the first electric gate 13, the second electric gate 131, the third electric gate 132, and the fourth electric gate 133, so as to prevent the mud and sand from blocking the gate and affecting the normal opening and closing of the gate. The mud and sand pushing components 7 include a second hydraulic cylinder 70 fixedly installed on the bottom leveling base 12. A pushing plate 71 is fixedly installed at the end of the telescopic shaft of the second hydraulic cylinder 70. A top baffle 72 is fixedly installed at the bottom of the front side plate of the pushing plate 71. The pushing plate 71 and The top baffle 72 has an inverted L-shaped cross section. The pusher plate 71 slides along the surface of the bottom leveling base 12. Specifically, the second hydraulic cylinder 70 is activated and put into operation. When the second hydraulic cylinder 70 is in operation, its telescopic shaft extends, which can drive the pusher plate 71 to move, thereby realizing the mud and sand pushing and cleaning operation. This allows the mud and sand to be pushed out after the first electric gate 13, the second electric gate 131, the third electric gate 132 and the fourth electric gate 133 are opened, so that the opening and closing parts of the first electric gate 13, the second electric gate 131, the third electric gate 132 and the fourth electric gate 133 are not obstructed.

[0052] When the present invention is used in the ship passage system on the river, for ships traveling from upstream to downstream or from downstream to upstream, the corresponding first electric gate 13 or fourth electric gate 133 is first opened to allow the ship to travel to the first waiting area 14 or the second waiting area 142. After the ship has traveled to the first waiting area 14 or the second waiting area 142, the corresponding first electric gate 13 or fourth electric gate 133 is closed. At this time, the ship is in the corresponding first waiting area 14 or the second waiting area 142.

[0053] Then open the corresponding solenoid valve 32, and at the same time connect the suction pump 60 to the external power supply and make it work. The suction pump 60 and the solenoid valve 32 work to discharge the water in the corresponding first waiting area 14 or second waiting area 142 to the outside, so that the water level in the first waiting area 14 or second waiting area 142 is lowered. After the water level is lowered to a suitable level, open the second electric gate 131 or the third electric gate 132. The ship travels to the low water level passage area 141 to wait. Then continue to discharge the water in the low water level passage area 141 until the height of the ship is lower than the height of the bridge. The ship then travels through the low water level passage area 141 and passes through the bridge.

[0054] After passing the bridge, the first hydraulic cylinder 52 is activated and put into operation. When the first hydraulic cylinder 52 is in operation, its telescopic shaft extends, causing the water inlet cover 531 to move downward. At this time, the water in the auxiliary water tank 11 can enter the low water level passage area 141 through the water inlet cover 531 and the water inlet pipe 57, so that the water level in the low water level passage area 141 can be close to the water level in the first waiting area 14 or the second waiting area 142. After the water level is close, the corresponding second electric gate 131 or the third electric gate 132 is opened, allowing the ship to travel from the low water level passage area 141 to the first waiting area 14 or the second waiting area 142. After the ship passes, the second electric gate 131 or the third electric gate 132 is closed, and water continues to be supplied to the first waiting area 14 or the second waiting area 142 until the water level is the same as the river surface. Then the corresponding first electric gate 13 or the fourth electric gate 133 is opened, allowing the ship to sail out, completing the low water level bridge passage operation.

[0055] In addition, when the drive motor 21 is connected to an external power source and made to work, the output shaft of the drive motor 21 rotates, driving the long shaft 22 and the scraper 23 to rotate, thereby scraping off the impurities on the arc-shaped mesh substrate 111 and preventing the impurities from clogging the arc-shaped mesh substrate 111.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
