Problems solved by technology

These goods are easy to cause pollution during the loading, unloading and stacking process. In addition, the oil, diesel oil and lubricating oil used by ship engines pollute the water surface and the oil fume pollutes the air. Therefore, the shipping terminal often gives people a sense of smog.

Embodiment 1

[0039] as attached figure 1 , 2 , 3, a kind of flexible dam of the present invention that is convenient for ships to pass immediately in the cascade drop waters includes two piers 2 and a dam body 11 that is connected between the two piers 2, and the dam body 11 has an upstream 18 height 1. The sloping surface of the downstream 1 is low, and the dam body 11 is arranged along the dam surface of the downstream 1 . The dam body 11 is a hollow and airtight cavity structure, and the inner cavity of the dam body 11 is equipped with a support frame 14 . The dam body 11 is in contact with the bottom wall of the ship 8, and the surface that is in contact with the ship 8 on the dam body 11 is made of a flexible material, and a roller 9 is horizontally installed on the surface. When the ship 8 passes through the flexible dam 3, the roller 9 Rolling contact with the bottom wall of the vessel 8 .

[0040] The supporting frame 14 involved is a plurality of vertical bars 13 for vertical s...

Embodiment 2

[0050] as attached Figure 4 As shown, the supporting frame 14 involved in the second embodiment includes a plurality of vertical partitions 15 arranged in parallel for longitudinal support, and the vertical partitions 15 divide the inner cavity of the dam body 11 into a plurality of connected independent spaces. Preferably, a cross bar 12 for lateral support is also included, and the cross bar 12 intersects with the vertical partition 15 and is connected and fixed together.

Embodiment 3

[0052] Embodiment three is the same as embodiment one, the difference is: as attached Figure 5 As shown, the supporting frame 14 involved in the third embodiment includes a plurality of vertical partitions 15 arranged in parallel for longitudinal support. The vertical partitions 15 divide the inner cavity of the dam body 11 into a plurality of independent spaces, and each independent space Offer communication hole 17 to communicate with other independent spaces. Preferably, it also includes a transverse partition 16 for lateral support, the transverse partition 16 intersects with the vertical partition 15 and is connected and fixed together, the transverse partition 16 and the vertical partition 15 divide the inner cavity of the dam body 11 into a plurality of Independent spaces, each independent space opens a communication hole 17 to communicate with other independent spaces.

Abstract

The invention provides a method convenient for a ship to instantly pass through a gradient fall water area and a flexible dam. The method comprises the following steps: (S1) the flexible dam is set to replace a traditional lock according to the magnitude of a present water area gradient fall; the flexible dam includes a dam body; the dam body is contacted with the outer wall of the ship; the surface, contacted with the ship, of the dam body is manufactured by a flexible material; and a roller is arranged on the surface; and (S2) when the ship is driven to the dam body, the ship advances under the effect of water current propulsion or propulsion of an engine set by matching with the ship; and when the ship passes through the flexible dam, the outer wall of the ship is in rolling contacted with the roller. The flexible dam is used for replacing the traditional lock; and when the ship passes through the flexible dam, the outer wall of the ship is contacted with the roller. The ship passes through the flexible dam by the water current propulsion, the ship engine set or the external traction; and through the structural design, a ship fleet has no need to immobilize for waiting during passing, so that the navigation capacity is improved, the pollution to the water area is prevented, and the body injury of sailors is reduced.

Description

technical field [0001] The invention relates to a ship-passing method used for navigation in water conservancy engineering construction, in particular to a method and a flexible dam for facilitating immediate passage of ships in cascade drop waters. Background technique [0002] The Beijing-Hangzhou Grand Canal was once known as the golden waterway, but today it is rarely paid attention to. The reason is that compared with the two major systems of railway and highway, the speed of water transport is too slow, and it is too troublesome to pass the lock. Sometimes it takes three or four days to pass the lock for a one-day voyage. Therefore, they are reluctant to choose water transport for goods that are slightly time-sensitive. Water transport can only undertake bulk cargo that is not time-sensitive, such as coal, sand, and stones. These goods are easy to cause pollution during loading, unloading and stacking. In addition, the oil, diesel and lubricating oil used by ship engi...
