Description

Technical Field

[0001] The utility model relates to the technical field of watershed safety design, in particular to a steel pontoon type ship arresting facility that changes amplitude automatically with water level. Background Art

[0002] Compared with the middle and lower reaches of the Yangtze River, the navigable rivers in western my country often experience large changes in water levels during flood seasons. This phenomenon is particularly evident in mountainous river basins. Since most of the rivers here are in the mountains, torrential rains form mountain torrents, carrying a large amount of soil, branches and other debris into the river. Due to the winding river channels and relatively large riverbed slopes, the water level rises significantly with the arrival of the flood peak. This characteristic of water levels changing significantly with the seasons places high demands on the safety and rationality of the design of ship arresting facilities.

[0003] Under the huge thrust of the flood and the entrainment of floating objects, the mooring force of ships anchored in the anchorage area for flood season increases sharply, resulting in cable breakage or mooring failure, resulting in "ship running away" accidents, causing losses to important bridges, power stations, dams and coastal buildings downstream and the safety of people's lives and property. At present, there are no facilities in China to prevent "ship running away" in the anchorage area of ​​mountainous rivers, so it is very necessary to set up a ship arresting facility that changes amplitude with the water level. Utility Model Content

[0004] The utility model aims to solve the deficiencies of the prior art and to provide a steel pontoon type ship arresting facility which can self-variate with the water level, so as to solve the problem of intercepting flood season ships which may "run away" due to cable breakage or mooring failure in the anchoring area during the flood season proposed in the above technical background, thereby protecting the safety of important downstream bridges, power stations, dams and coastal buildings and the lives and property of the people.

[0005] The utility model is realized by the following technical solutions:

[0006] A steel pontoon type ship arresting facility that changes its amplitude according to the water level, comprising:

[0007] An interception device, the interception device includes a first interception component and a second interception component respectively arranged on both sides of the ship area, the first interception component and the second interception component can both float on the water surface, and the first interception component and the second interception component are hinged to the shore at one end close to their respective shores; the other ends of the first interception component and the second interception component are respectively provided with mutually cooperating quick-detachable joints, and the quick-detachable joints are used to realize the opening and closing between the first interception component and the second interception component.

[0008] Compared with the prior art, under the huge thrust of the flood and the entrainment of floating objects, the mooring force of the flood-crossing ships docked in the ship anchorage area increases sharply, resulting in cable breakage or mooring failure, causing "ship running away" accidents, and causing losses to important downstream bridges, power stations, dams and coastal buildings and the safety of people's lives and property. The utility model provides a steel pontoon-type ship arresting facility with self-variable amplitude according to the water level, so as to solve the problem of intercepting flood-crossing ships that have "ship running away" accidents caused by cable breakage or mooring failure in the ship anchorage area during the flood season proposed in the above technical background, thereby ensuring the safety of important downstream bridges, power stations, dams and coastal buildings and the safety of people's lives and property. In the specific scheme, the ship interception facility is arranged at the entrance and exit of the ship anchorage area, and includes a first interception component and a second interception component which are respectively arranged in the left and right parts. The first interception component and the second interception component have the same structure and can float on the water surface. One end of the first interception component and the second interception component are hinged to the shore. Therefore, when not working in the non-flood period, the first interception component and the second interception component of the left and right parts are disconnected from the middle quick-detachable joint, and are towed by engineering vessels on both sides of the river respectively, and float and park along the banks on both sides, which will not affect the free entry and exit of ships; when working in the flood period, the first interception component and the second interception component of the left and right parts are towed by engineering vessels respectively, and connected and closed from the middle quick-detachable joint; when the flood-related ships docked in the ship anchorage area occasionally have a "runaway" accident due to cable breakage or mooring failure, the ship floats and hits the ship interception facility composed of the first interception component and the second interception component under the action of water flow, thereby realizing the ship's stop, and ensuring the safety of important downstream bridges, power stations, dams and coastal buildings and the lives and property of the people.

[0009] A further solution is that, in order to achieve a stable connection, both sides of the ship area are provided with supporting structures, and one end of the first interception component and the second interception component are provided with a rocker arm, and the rocker arm is hinged to the supporting structure.

[0010] According to a further solution, in order to achieve floating of the interception facility on the water surface, the first interception assembly and the second interception assembly each include a plurality of steel pontoons arranged in sequence at intervals, and the plurality of steel pontoons are connected by traction arresting cables.

[0011] A further solution is to provide a plurality of traction arresting cables to achieve a stable connection between the steel pontoons and prevent the steel pontoons from tipping over, wherein the plurality of traction arresting cables are connected to the top and bottom surfaces of the steel pontoons.

[0012] A further solution is that, in order to facilitate the connection of the towing arresting cable on the steel pontoon, the top and bottom surfaces of the steel pontoon are provided with arresting cable clamps for fixedly connecting the towing arresting cable, and the arresting cable clamps are provided with a plurality of rings for the towing arresting cable to pass through.

[0013] A further solution is to provide a concrete filling area inside the steel pontoon in order to make the pontoon reach the designed draft weight and lower the center of gravity of the pontoon and increase the restoring moment of the pontoon.

[0014] A further solution is to prevent the swaying of concrete and enhance the structural strength of the pontoon to reduce structural damage. The concrete filling area in the steel pontoon is provided with a permeable empty box area below and a polyurethane filling area above. The permeable empty box area can allow river water to pass through, so as to reduce the thrust of the river water on the pontoon.

[0015] According to a further solution, one end of the first interception assembly and the second interception assembly is also provided with a transition pontoon, and the transition pontoon is connected to the rocker arm.

[0016] A further solution is that in order to tension the ship interception facility when it is hit and absorb the energy of the ship's impact, the bottom of the transition buoy has an energy-absorbing weight suspended in the water.

[0017] A further solution is that in order to dissipate energy by stretching through elastic deformation during interception, the traction arresting cable is provided with a decompression ring.

[0018] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0019] 1. The utility model provides a steel pontoon type ship arresting facility that changes its amplitude according to the water level. The combination of the steel pontoon, the traction arresting cable and the transition pontoon can adapt to the amplitude change of the large water level difference during the flood period; and each device can be assembled on site, with low installation difficulty.

[0020] 2. The utility model provides a steel pontoon type ship arresting facility that changes its amplitude with the water level. After the installation of the ship arresting facility is completed, the out-of-control ship drives the steel pontoon to move, and the kinetic energy of the ship is consumed by water resistance. The decompression rings between the arresting cables are elastically deformed and stretched, thereby providing resistance and consuming the kinetic energy of the ship. The energy-absorbing weight placed in the transition pontoon at the end of the arresting cable is pulled up, and the kinetic energy of the ship is consumed by overcoming the gravity force of the weight. Therefore, the present invention can change its amplitude with the change of water level, and the structure is simple to install. At the same time, it also realizes the organic combination of water resistance energy dissipation, decompression energy dissipation, and lifting weight energy dissipation, and has high practicality.

The schematic implementation manner of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model.

[0030] Example:

[0031] This embodiment provides a steel pontoon type ship arresting facility which can automatically change its amplitude according to the water level, such as Figure 1-Figure 5 As shown, including:

[0032] The interception device comprises a first interception assembly and a second interception assembly respectively arranged on both sides of the ship area, the first interception assembly and the second interception assembly can both float on the water surface, and one end of the first interception assembly and the second interception assembly close to their respective shores are hinged to the shore; the other ends of the first interception assembly and the second interception assembly are respectively provided with mutually cooperating quick-detachable joints 9, and the quick-detachable joints 9 are used to realize the opening and closing between the first interception assembly and the second interception assembly.

[0033] Compared with the prior art, under the huge thrust of the flood and the entrainment of floating objects, the mooring force of the flood-crossing ships docked in the ship anchorage area increases sharply, resulting in cable breakage or mooring failure, causing "ship running away" accidents, and causing losses to important downstream bridges, power stations, dams and coastal buildings and the safety of people's lives and property. The utility model provides a 6-type steel pontoon ship arresting facility with self-variable amplitude according to the water level, so as to solve the problem of intercepting flood-crossing ships that have "ship running away" accidents in the ship anchorage area during the flood season due to cable breakage or mooring failure proposed in the above technical background, thereby ensuring the safety of important downstream bridges, power stations, dams and coastal buildings and the safety of people's lives and property. In the specific scheme, the ship interception facility is arranged at the entrance and exit of the ship anchorage area, and includes a first interception component and a second interception component respectively arranged in the left and right parts. The structures of the first interception component and the second interception component are the same, and both can float on the water surface. One end of the first interception component and the second interception component are hinged to the shore. Therefore, when not working in the non-flood period, the first interception component and the second interception component of the left and right parts are disconnected from the middle quick-detachable joint 9, and are towed by engineering ships on both sides of the river respectively, and float and park along the banks on both sides, which will not affect the free entry and exit of ships; when working in the flood period, the first interception component and the second interception component of the left and right parts are towed by engineering ships respectively from the middle quick-detachable joint 9 to connect and close; when the flood-related ships docked in the ship anchorage area occasionally have a "runaway" accident due to cable breakage or mooring failure, the ship floats and collides with the ship interception facility composed of the first interception component and the second interception component under the action of water flow, thereby realizing the ship's stop, and ensuring the safety of important downstream bridges, power stations, dams and coastal buildings and the lives and property of the people.

[0034] In this embodiment, in order to achieve a stable connection, both sides of the ship area are provided with a supporting structure 1, and one end of the first interception component and the second interception component are provided with a rocker arm 2, and the rocker arm 2 and the supporting structure 1 are hinged.

[0035] In this embodiment, in order to achieve the floating of the interception facility on the water surface, the first interception assembly and the second interception assembly each include a plurality of steel pontoons 6 arranged in sequence and spaced apart, and the plurality of steel pontoons 6 are connected by traction arresting cables 5.

[0036] In this embodiment, in order to achieve a stable connection between the steel pontoons 6 and prevent the steel pontoons 6 from flipping over, there are a plurality of traction arresting cables 5, and the plurality of traction arresting cables 5 are connected to the top and bottom surfaces of the steel pontoons 6.

[0037] In the present embodiment, in order to facilitate the connection of the traction arresting cable 5 to the steel pontoon 6, the top and bottom surfaces of the steel pontoon 6 are provided with an arresting cable clamp plate 7 for fixing the traction arresting cable 5, and the arresting cable clamp plate 7 is provided with a plurality of rings for the traction arresting cable 5 to pass through.

[0038] In this embodiment, in order to make the pontoon reach the designed draft weight and lower the center of gravity of the pontoon, and increase the restoring moment of the pontoon, the steel pontoon 6 is provided with a concrete filling area.

[0039] In this embodiment, in order to prevent the shaking of concrete and enhance the structural strength of the pontoon, and reduce structural damage, the concrete filling area in the steel pontoon 6 is provided with a permeable empty box area below and a polyurethane filling area above. The permeable empty box area can allow river water to pass through, so as to reduce the thrust of the river water on the pontoon.

[0040] In this embodiment, one end of the first interception assembly and the second interception assembly is further provided with a transition pontoon 3 , and the transition pontoon 3 is connected to the rocker arm 2 .

[0041] In this embodiment, in order to be tensioned as the ship interception facility is hit and absorb the energy of the ship impact, the bottom of the transition pontoon 3 is provided with an energy-absorbing weight 4 suspended in the water.

[0042] In this embodiment, in order to dissipate energy by stretching through elastic deformation during interception, the traction arresting cable 5 is provided with a decompression ring 8.

[0043] Working principle: The ship arresting facility is arranged at the entrance and exit of the ship anchoring area, divided into two sections, and connected in the middle by a quick-release joint 9 of an arresting cable. When not working in the non-flood period, the left and right sections of the ship arresting facility are disconnected from the middle quick-release joint 9 and floated along the shores on both sides. When working in the flood period, the left and right sections are respectively towed by auxiliary ships to the entrance and exit of the ship anchoring area and connected and closed by quick-release joints 9. The steel pontoon 6 of the facility provides buoyancy for the device to float on the water surface, the arresting cable provides interception force for the device, and the transition pontoon 3 and the rocker 2 device combination adapt to the water level fluctuation during the flood period. When the flood-proof ships docked in the ship anchoring area sometimes have a "running ship" accident due to the failure of the mooring cable, the ship floats and hits the ship arresting facility under the action of the water flow, and the pontoon moves horizontally with the collision. During the movement, the underwater part of the pontoon provides an interception torque through the water resistance reaction force to consume the ship's kinetic energy. As the ship arresting facility is impacted and tensioned, the decompression ring 8 between the arresting cables is elastically deformed and stretched, thereby providing resistance and consuming the ship's kinetic energy. As the arresting ship facility is impacted and tensioned, the energy-consuming weight 4 placed in the transition buoy 3 at the end of the arresting cable is pulled up, and the kinetic energy of the ship is consumed by doing work to overcome the gravity force of the weight.

[0044] Working process: Referring to the attached figure, the upper part of the figure is the entrance and exit of the ship anchorage area, and the lower part of the figure is the ship anchorage area. When a ship docked in the ship anchorage area for flood season sometimes has a "runaway" accident due to the failure of the mooring cable, the ship floats and hits the ship arresting facility under the action of the water flow, and the steel pontoon 6 moves horizontally with the collision. During the movement process, the underwater part of the steel pontoon 6 provides an interception torque through the water resistance reaction force to consume the ship's kinetic energy. As the arresting ship facility is impacted and tensioned, the decompression ring 8 between the traction arresting cable 5 is elastically deformed and stretched, thereby providing resistance and consuming the ship's kinetic energy. As the arresting ship facility is impacted and tensioned, the energy-consuming weight 4 at the end of the traction arresting cable 5 located in the transition pontoon 3 is pulled up, and the kinetic energy of the ship is consumed by overcoming the gravity force of the weight. When the water level changes during the flood period, the transition pontoon 3 and the rocker arm 2 are combined to adapt to the water level changes during the flood period. It can be seen that the ship arresting facility has a simple structure, is easy to install and operate, and can adaptively change amplitude with water level changes.

It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
