Description

Technical Field

[0001] The invention relates to a channel device for boarding a ship, in particular to a channel device applied to the bow of a small boat for facilitating people to board the boat. Background Art

[0002] In order to have a wider view of the cab, the conditions for opening doors may not be available above the main deck of the boat. When the bow of the boat reaches the beach, the bow channel equipment is required to provide a channel for personnel to board the boat and enter the cabin under the main deck. During navigation, the channel equipment has a certain degree of tightness to ensure that water does not enter the cabin. However, the prior art only has a channel facility for PMA inspection in the cargo hold of an oil tanker disclosed in CN113636015A, drillships for rescue and access channel facilities disclosed in KR1020130050497A, a channel device for ship inspection disclosed in CN100545608C, and a channel device for ship inspection disclosed in CN1834605A. These channel facilities and channel equipment are not suitable for the requirements of boarding and transportation of personnel arriving at the beach by high-speed boats. Therefore, it is necessary to rely on the development project of new high-speed boats, analyze the requirements of high-speed boats for channel equipment based on the boarding and transportation needs of high-speed boats arriving at the beach, and develop a bow channel equipment for boats. Summary of the invention

[0003] The present invention provides a bow passage device for a boat, which can meet the needs of people boarding and transporting people to the beach when the high-speed boat is approaching. When opened, it provides a passage for people to board the boat from the bow. When closed, it can ensure the tightness of the forepeak tank without destroying the integrity of the bow of the boat.

[0004] To achieve the above-mentioned purpose, the technical solution of the present invention is: a bow passage device for a boat, including a hatch cover, a gangway, a hatch cover opening and closing device, a hatch cover locking device, a gangway cable collection device, a gangway locking device, and a control box. The hatch cover is arranged on the main deck, connected to the hatch cover opening and closing device and the hatch cover locking device, and the hatch cover is driven by the hatch cover opening and closing device to open and close. After the hatch cover is closed, it is locked by the hatch cover locking device to ensure tightness; the gangway is arranged in front of the hull, below the hatch cover, and connected to the gangway cable collection device and the gangway locking device. The gangway is driven by the gangway cable collection device to open and close. After the gangway is closed, it is locked by the gangway locking device to ensure tightness.

[0005] Furthermore, the hatch cover is hinged on the fence 1 on the hull; the hatch cover opening and closing device is connected between the fence 1 and the hatch cover; and the hatch cover locking device is fixed on the hatch cover.

[0006] Furthermore, the hatch cover is folded upward when in use, and is closed after use to ensure airtightness between the hatch cover and the cabin body.

[0007] Furthermore, the gangway is hinged on the fence 2 on the hull; the gangway cable collection device and the gangway locking device are fixed on the base in the forepeak cabin.

[0008] Furthermore, the springboard rope collection device adopts electric or hydraulic power, and is connected to the rope on the springboard through a pulley block to collect and release, thereby controlling the opening and closing of the springboard.

[0009] Furthermore, the gangplank is folded downwards and opened when in use, and is closed after use to ensure tightness between the gangplank and the main hull.

[0010] Furthermore, the hatch cover opening and closing device and the gangway cable collection device are both powered telescopic cylinders, and the telescopic cylinders are electric cylinders or hydraulic cylinders.

[0011] Furthermore, the hatch cover locking device and the gangway locking device use electric means to lock the lock hook or the lock tongue with the structure on the hatch cover or the gangway.

[0012] Furthermore, sealing devices are provided between the hatch cover and the fence, between the two hatch covers, between the hatch cover and the gangway, and between the gangway and the fence to ensure the tightness after closing.

[0013] Furthermore, the control box is fixed on the base inside the cabin and is used to remotely control the hatch cover opening and closing device, the hatch cover locking device, the gangway cable collection device, and the gangway locking device.

[0014] The beneficial effects of the present invention are:

[0015] The bow passage device for boats of the present invention provides a passage for people to board the boat from the bow when it is opened, and can ensure the tightness of the forepeak cabin when it is closed without destroying the integrity of the bow of the boat. It is equipped with a hatch locking device and a gangway locking device, which can be locked after closing to maintain tightness under no-power conditions. The device can meet the needs of people boarding and transporting high-speed boats when they arrive at the beach. BRIEF DESCRIPTION OF THE DRAWINGS
