Description

Device for quickly arranging and recovering unmanned light fish-luring boat

Technical Field

The utility model relates to a boats and ships facility technical field especially relates to a quick cloth of unmanned light fish attracting boat is put and recovery unit.

Background

At present, manned boats at home and abroad mainly adopt three distribution and recovery technical schemes of a hanging type, a stern slideway type and a dock cabin type.

The lifting type retraction technology is widely applied to various naval vessels, civil ships and other special ships, and the technology is relatively mature. The lifting type retraction technology comprises a single lifting point and a double lifting point. The single-lifting-point technology is generally suitable for small boats with the length not more than 7.5m, and is increasingly emphasized due to high reliability and simple operation; the double-lifting-point technology is better in stability when lifting the boat, but is difficult to operate and high in danger, and is more suitable for the boat with the length exceeding 7.5 m. Three kinds of hanging type retraction devices are most commonly adopted on foreign large ships, including rotary type, A-frame type and telescopic type. The broadside hanging type retractable equipment can be arranged in a cabin and can also be arranged in an open air part, and when the cabin is arranged, an opening needs to be arranged on the broadside; the stern telescopic arm hanging type retraction equipment is arranged in a cabin, and an opening needs to be formed in the stern of a mother ship.

The stern slideway retraction technology is mainly applied to various naval vessels, business vessels and foreign trade vessels, and comprises a single slideway system and a double slideway system. During recovery, the USV (unmanned surface vessel) selects a proper flushing time, flushes into the stern slideway at a speed higher than the navigation speed of the mother ship, is automatically hooked by the arresting cable in front of the slideway and the ship bow hook mechanism, and the arresting buffer mechanism absorbs the kinetic energy of the USV during flushing and stops the USV in a short distance, so that the USV is recovered. When the USV is released, the electric control mechanism of the USV automatically opens the hook, the boat bow is separated from the stopping cable at the moment, and the USV slides down to the water surface by means of dead weight. If the external wind waves are large, the blocking and tensioning device can be adopted to push the USV to a position close to the water surface, and then the USV slides downwards freely. The retraction mode needs manual auxiliary remote control operation to overcome the influence of wake flow and aims at the retraction device to rush into the slideway. The collecting and releasing equipment can be arranged in the cabin and can also be arranged in the open air, but an opening needs to be arranged at the stern of the mother ship.

Compared with other retraction technologies, the dock cabin retraction is easier to realize. The dock cabin type rapid retraction equipment is arranged in a cabin, a large dock cabin needs to be configured at the stern, special requirements are provided for a hull structure, and at present, no application case for rapidly retracting and retracting the USV in the dock cabin exists at home and abroad. The dock cabin type distribution and recovery are divided into a dock cabin bracket type and a dock cabin slideway type according to the launching mode of the boat. The dock bay bracket type retraction system is characterized in that the USV is stored on a bracket in the dock bay, the bay door is opened to fill water into the bay before the USV leaves the bay, the USV on the bracket floats at the moment, then the locking device is opened, the USV drives away from the bracket in a remote control mode to complete the deployment, and the retraction process is opposite to the retraction process. The dock cabin slideway type retraction system is characterized in that an inclined slideway is arranged in the dock cabin, a cabin door is opened to inject water into the cabin during recovery, the USV of the system can be recovered in various modes such as a traction winch only by driving into the inclined slideway, and the USV only needs to slide into water from the slideway during distribution. The collecting and releasing system can use a collecting and releasing device of a manned boat for reference, and collecting and releasing equipment of the collecting and releasing system is arranged in a cabin and can be shielded and stored by a stern door.

The dock cabin type rapid deployment and recovery technology is not greatly influenced by factors such as navigational speed, sea conditions and the like, and is most suitable for deployment and recovery of the small boats in a complex wave environment; the suspension type distribution and recovery technology has poor adaptability to the navigation speed and sea conditions of a mother ship, time-consuming operations such as manual hook release and the like, has low safety, and is not suitable for the distribution and recovery of small boats under complex sea conditions; the stern slideway type distribution and recovery technology is centrally embodied in the aspects of the navigation speed of a mother ship, the adaptation to sea conditions, the operation condition, the time consumption of distribution and recovery and the like.

When the arrangement and recovery device is used, the mother ship is required to provide necessary ship structure arrangement or a specific crane, for example, an opening is required to be arranged at the stern of the mother ship in a stern slideway retraction technology; the dock cabin type rapid laying and recovering technology needs to arrange a large dock cabin on a stern and has special requirements on a hull structure; the hoisting and releasing type retraction technology needs to recover a crane with a service radius more than 3 meters provided by a mother ship. At present, only a mast crane is arranged on a light purse seiner, the service radius of the mast crane can only extend out of the ship board by 0.5-1.5 meters, the lifting weight is 3-5 tons, and the special requirements of the current unmanned ship laying and recovering technology on a ship body structure and the crane cannot be met.

Therefore, a rapid deployment and recovery device for an unmanned light fish-luring boat is urgently needed in the market for solving the problems.
