Description

Technical Field

[0001] The utility model belongs to the technical field of ship berthing devices, in particular to a large ship berthing device adapted to daily regulation of reservoir water level fluctuation. Background Art

[0002] Due to the development and construction of hydropower stations, many rivers that were not navigable before have reservoirs with navigation conditions for large ships. There are often a lot of projects to be built upstream of the reservoir, but some reservoirs have no built roads, so large ships are needed to transport materials in the reservoir area.

[0003] Many reservoirs have daily regulation performance. The water level in the reservoir area will fluctuate greatly between the dead water level and the normal water level every day. If there is no safe and reliable berthing device, the large water level fluctuation will seriously affect the berthing safety of large ships. For example, a sharp drop in the water level in the reservoir area at night will cause the ship to run aground or even sink on a reef. Most of the berthing devices that can adapt to water level fluctuations are built before the reservoir area is filled with water when there are dry land construction conditions. If you want to build a berthing device that can adapt to water level fluctuations after the reservoir area is filled with water, you will face many unfavorable factors such as difficult underwater construction, complex procedures, long construction period and large investment.

[0004] Therefore, when deciding to put large ships into use after the reservoir is filled with water, there is an urgent need for a large ship berthing device with simple construction, short construction period and low investment. Utility Model Content

[0005] In view of the technical problems existing in the background technology, the utility model provides a large ship berthing device suitable for daily regulation of reservoir water level fluctuation, which has simple construction, short construction period and low investment.

[0006] In order to achieve the above purpose, the technical solution provided by the utility model is:

[0007] A large ship berthing device adapted to daily regulation of reservoir water level fluctuations, comprising a plurality of berthing piers, a plurality of independent mooring piles and a dry stone slope;

[0008] The mooring piers are arranged across the dry stone slope at a certain interval;

[0009] The independent mooring piles are arranged above the dry stone slope at a certain interval.

[0010] Preferably, the dry stone slope is set with a slope I1, the lowest point of the dry stone slope is the same as the dead water level elevation of the reservoir, and the highest point is greater than the normal water level elevation of the reservoir.

[0011] Preferably, the slope I1 ranges from 1:1.5 to 1:2.

[0012] Preferably, a plurality of slope protection steel bar gabions are arranged at the lowest point of the dry stone slope.

[0013] Preferably, the mooring pier is made of concrete.

[0014] Preferably, the edge of the bottom of the mooring pier is arranged as a step portion and embedded in the dry stone slope.

[0015] Preferably, the slope of the step portion ranges from 1:0.5 to 1:1.

[0017] The auxiliary mooring piles, escape ladders and anti-collision devices are respectively arranged on the side of the mooring pier close to the reservoir.

[0018] Preferably, the anti-collision device is made of waste tires or ship anti-collision fenders.

[0019] The utility model has the following advantages and beneficial effects:

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example 1

[0032] A large ship berthing device adapted to daily regulation of reservoir water level fluctuations, comprising a plurality of berthing piers 1, a plurality of independent mooring piles 3 and a dry stone slope 7;

[0033] The mooring piers 1 are arranged across the dry stone slope 7 at a certain distance, and the arrangement spacing here can be flexibly set according to the specific length of common ships;

[0034] The independent mooring piles 3 are arranged above the dry stone slope 7 at a certain interval. Generally speaking, the spacing between the independent mooring piles 3 is generally recommended to be greater than the length of the hull 2, which will be more conducive to ensuring the stability of the mooring of the ship's cable 4.

[0035] When put into use, the ship mooring pile on the ship is connected to the independent mooring pile 3 through the cable 4 for positioning and mooring the ship 2. The mooring device is stable, reliable and easy to build.

[0036] Example 2

[0037] This embodiment is based on the technical solution of Embodiment 1, and mainly further explains the setting of the dry stone slope 7.

[0038] In this embodiment, the dry stone slope 7 is set with a slope I1, and can be protected by blocks of stone. The lowest point of the dry stone slope 7 is the same as the dead water level elevation 8 of the reservoir, and the highest point is greater than the normal water level elevation 9 of the reservoir. The construction of the entire large ship berthing device can be carried out completely after the reservoir is filled with water. During construction, there is no need for many engineering measures such as cofferdam pumping, underwater pile driving, underwater concrete pouring, etc., which can effectively save investment and reduce construction period.

[0039] Furthermore, the slope I1 has a value range of 1:1.5 to 1:2.

[0040] As a preferred solution, a plurality of slope protection steel bar gabions 6 are arranged at the lowest point of the dry stone slope 7 to ensure that the entire dry stone slope 7 can maintain its own safety and stability within the range of normal water level fluctuation H1 of the reservoir.

[0041] Example 3

[0042] This embodiment is based on the technical solution of Embodiment 1, and mainly further explains the setting of the mooring pier 1.

[0043] In this embodiment, the material of the mooring pier 1 is concrete. The width of the mooring pier 1 can be determined according to actual needs on site, for example, the width of the mooring pier 1 can be preferably 3m.

[0044] As a preferred solution of this embodiment, the edge of the bottom of the mooring pier 1 is set as a step part and embedded in the dry stone slope 7.

[0045] Preferably, the slope I2 of the step portion is in the range of 1:0.5 to 1:1, which can effectively save the amount of concrete and ensure the safety and stability of the mooring pier 11 itself.

[0046] On the other hand, the mooring pier 1 further comprises an auxiliary mooring pile 11 , an escape ladder 12 and an anti-collision device 13 ; the auxiliary mooring pile is also used for fixing to the mooring pile 5 of the hull 2 ​​itself via a cable 4 .

[0047] The auxiliary mooring pile 11, the escape ladder 12 and the anti-collision device 13 are respectively arranged on the side of the mooring pier 1 close to the reservoir.

[0048] Furthermore, the anti-collision device 13 uses waste tires or marine anti-collision fenders, which can be used to reduce the collision damage between the hull 2 ​​and the mooring pier 1. The reservoir area along the dry stone slope 7 needs to be cleaned to ensure that the harbor depth H2 is greater than the draft depth of the ship at the dead water level elevation 8, so that the ship can be safely moored under the normal water level fluctuation H1 in the reservoir area, and will not run aground at the lowest water level.

[0049] refer to Figure 3 and Figure 4, a schematic diagram of an independent mooring pile 3 or an auxiliary mooring pile and a schematic diagram of the arrangement of an anti-collision device 13 are given. The types of mooring piles can be various. The embodiment of the utility model provides a pre-buried cross mooring pile; the anti-collision device 13 is mainly used to reduce the collision damage between the hull 2 ​​and the mooring pier 1.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
