Abstract

A wave-proof dock gate at an inlet of a U-shaped code relates to the U-shaped code construction technology, in particular to a wave-proof dock gate at an inlet of a U-shaped code. The dock gate control device comprises two oppositely-opened dock gates arranged at an inlet of a U-shaped code head, a power device for driving the dock gates to be opened or closed, and a supporting device for controlling the state stability of the dock gates; the dock gate is of a sealed box structure, and a dock wall at the entrance of the U-shaped dock is provided with a connected hinge which is connected with the near-shore side of the dock gate; and on the far bank side of the dock gate without a hinge, the dock gate in a closed state is fixed with the dock bank wall by a rigid connecting rod. The U-shaped wharf entrance wave-proof dock gate provided by the invention can block the influence of waves, ocean currents and tidal surges outside the entrance on a ship operating in a wharf, forms a completely closed ship loading and unloading operation environment in the U-shaped wharf, and has the positive effects of small power consumption for opening and closing, stability, reliability, and rapidness and convenience for opening and closing.

Description

U-shaped wharf entrance wave-proof dock gate

Technical Field

The invention relates to a U-shaped wharf building technology, in particular to a wave-proof dock gate at an inlet of a U-shaped wharf.

Background

In order to prevent the impact of the waves in the external sea area on the port berthing operation ship, the current measures are generally to build a wave-blocking breakwater at the periphery of the port wharf, and no other method is provided for solving the influence of the wave surge on the impact of the berthing operation ship.

In the prior patent application, a design scheme related to a U-shaped wharf exists, and the design scheme has a good wave impact prevention effect due to the function design of a similar breakwater. However, in the severe and complicated hydrological conditions, such as large wind waves or small angle between the direction of the ocean current and the entrance of the U-shaped wharf, the ships and facilities in the U-shaped wharf are still affected by the waves from the entrance.

Disclosure of Invention

The invention aims to provide a U-shaped code head entrance wave-proof dock gate which is matched with a U-shaped code head and achieves the purpose of providing a wave-proof barrier which can be flexibly opened or closed at the entrance.

The invention provides a wave-proof dock gate at a U-shaped code head inlet, which comprises two oppositely-opened dock gates arranged at the U-shaped code head inlet, a power device for driving the dock gate to be opened or closed, and a supporting device for controlling the state of the dock gate to be stable; the dock gate is of a sealed box structure, and a connection hinge is arranged on a wharf shore wall of a U-shaped wharf inlet and is connected with the near-shore side of the dock gate; a circular hole is formed in the part, immersed in water, of the far bank side of the dock gate, which is not provided with a hinge, and a propeller is arranged in the hole and driven by electric power; the supporting device for controlling the stable state of the dock gate is a three-dimensional triangular support, the supporting device is installed on the outer side of a dock gate installation hinge embedded in the U-shaped wharf inlet, the three-dimensional triangular support is fixed on the quay wall, and the three-dimensional triangular support and a fixed rod connected with the three-dimensional triangular support are used for fixing the open-state wave-proof dock gate; the dock gate in a closed state is fixed with the quay wall by a rigid connecting rod.

The invention has the following beneficial effects:

1) buoyancy generated by the closed box body is used for reducing stress of a connecting hinge for suspending the dock gate, so that resistance of the dock gate during opening and closing is reduced;

2) the propeller is driven by electricity to control the opening and closing of the dock gate, and compared with an electric push rod, a hydraulic cylinder and the like, the propeller is not assembled with an external structural part, is not limited by an external space, is simple and convenient to install, and is flexible to control.

In a word, the U-shaped wharf inlet wave-proof dock gate provided by the invention can block the influence of waves, ocean currents and tidal surges outside the inlet on a ship operated in a wharf, a completely closed ship loading and unloading operation environment is formed in the U-shaped wharf, and the U-shaped wharf inlet wave-proof dock gate has the positive effects of small power consumption in opening and closing, stability, reliability and quickness and convenience in opening and closing.

Drawings

FIG. 2 is a front view of the open state of the present invention;

FIG. 3 is a top view of the present invention.

Detailed Description

As shown in fig. 1-3, two opposite dock gates 4 are installed in water at the entrance of the U-shaped dock, and when a ship enters into a dock for operation, the dock gates 4 are closed by power to block the impact of the surge outside the entrance of the U-shaped dock on the ship for berthing operation. The dock gate is divided into two pieces, the bottom edge is higher than the sea bottom when the dock gate is installed, the dock gate is a steel structure box body with a local seal, and a closed floating box 7 is added on the vertical face of the dock gate when necessary to obtain larger buoyancy, so that the pressure of a connecting hinge 2 hung on the upstream face dock wall 1 at the entrance of the U-shaped dock is reduced, and the resistance of the dock gate when the dock gate is opened and closed is reduced. A round hole is formed in the middle of the immersed water on the side, where the hinge is not installed, of the dock gate, a ship propeller 5 is installed in the hole, and the propeller is driven by a motor to control the opening and closing of the dock gate. Under the condition that a hydraulic station is arranged nearby, the propeller can be driven by the hydraulic motor, and the hydraulic motor has the characteristics of high safety and reliability in operation and control.

In the embodiment shown in the attached drawings, a U-shaped wharf is of a trestle structure, two caissons are arranged at the inlet of the U-shaped wharf, a hinge 2 is installed on a dock gate which is pre-embedded when the upstream surface of the caisson is prefabricated, a triangular support 3 with a three-dimensional structure is installed on the outer side of the hinge, the three-dimensional triangular support is fixed on the wall of the caisson, and a fixing rod 8 on the three-dimensional triangular support is used for fixing the dock gate in an open state; the dock gate is fixed with the wharf by a rigid connecting rod 6 in a closed state.
