The small buoy has the diameter of about 1m, has the advantages of small volume, light weight, low price, convenience in distribution and recovery and the like, and is widely applied in recent years, such as a wave buoy, a water quality buoy, an emergency nuclear monitoring buoy and the like.

The device mainly includes supporting slide rail 1 and the conveyor 2 who sets up, and when using, the lower extreme of slide rail 1 stretches into under the surface of water, and the buoy is located conveyor 2. When the conveying device 2 slides downwards relative to the slide rail 1 to the position below the water surface, the buoy is separated from the conveying device 2 under the buoyancy action of the water and floats on the water surface, so that the buoy can be conveniently distributed. When the buoy which is already distributed is recovered, the conveying device 2 moves to the position below the water surface along the slide rail 1 and enables the ship to stop at the side edge of the buoy, so that the buoy is positioned above the conveying device 2, and then the conveying device 2 is driven to move upwards along the slide rail 1, so that the buoy falls onto the conveying device 2, and the buoy is recovered.

It should be noted that when the buoy is recovered, the conveyor 2 moves along the slide rails 1 to the position under the water surface, and the buoy is located at the upper side of the movement direction of the conveyor 2, so that the buoy can just fall into the conveyor 2 when the conveyor 2 slides upwards along the slide rails 1.

Specifically, in order to conveniently realize the arrangement and the recovery of the buoy, the upper surface of the conveying device 2 is provided with a containing cavity for containing the buoy, and when the buoy is placed in the containing cavity, the containing cavity is still provided with a vacant space. In addition, it should be noted that the density of the transfer device 2 is greater than the density of the seawater.

Specifically, the section of the slide rail 1 is in an I-shaped structure, and the bottom end of the conveying device 2 is provided with a corresponding structure matched with the I-shaped structure, so that the conveying device 2 can be always stably engaged on the slide rail 1.

Most importantly, the lower end of the sliding rail 1 is provided with a closing device, and the sliding can be stopped when the conveying device 2 slides to the closing device, so that the conveying device 2 is prevented from falling off from the sliding rail 1.

As an alternative embodiment, the closure device is made of a rubber material. The sealing device made of rubber materials has a certain shock absorption effect and can help to prolong the service life of the device. In addition, any material with better elasticity and shock absorption effect, such as silica gel and the like, can also be used for processing and manufacturing the sealing device.

In order to increase the durability of the slide rail 1, as an alternative embodiment, the slide rail 1 is made of a high-strength steel material. In addition, considering that the slide rail 1 needs to be soaked in seawater during operation, and in order to improve the durability and avoid corrosion, the outer side of the slide rail 1 is provided for nickel-chromium plating treatment or plastic coating treatment.

It should be noted that the slide rail 1 is detachably fixed on the side of the ship, which makes the device more portable, and at the same time, reduces the requirements for the ship, making it more flexible to use. In order to realize the detachable connection of the slide rail 1 and the ship board, as an optional embodiment, the retraction device further comprises a support, the support comprises two support arms 3, the support arms 3 are respectively located at the inner side and the outer side of the ship board and are used for clamping the ship board, at this time, the support and the slide rail 1 jointly form a U-shaped structure with a small opening, and the upper end of the slide rail 1 is fixed on the ship board through the support.

The slide rail 1 is arranged on the ship board through a support, so that when the buoy needs to be collected or the buoy collecting and releasing device needs to be collected, the corresponding device can be conveniently mounted and dismounted, the operation flexibility is greatly improved, and the requirements of the operation on the ship are reduced.

Specifically, the slide rail 1 may be fixedly connected to the bracket by welding, bolting, or the like.

It should be noted that the size of the opening of the U-shaped structure formed by the bracket and the slide rail 1 is much smaller than the distance between the intersection points of the two supporting arms 3 and the bracket.

As an alternative embodiment, the end of the support on the inboard side of the vessel is attached to the inboard wall of the vessel, as shown in figures 2-3.

So set up and to strengthen effectively fixing between support and the ship board, avoid the support to rock for the ship board produces, and then influence the efficiency that receive and releases of buoy.

The support can be suitable for various types of common ships such as common fishing boats, engineering boats and the like, the requirement on the type of the ship is not high, and an operator can conveniently find an operation ship meeting the requirement on site. It should also be noted that the support may be mounted port or starboard of the vessel.

The buoy slides to the inclined section 12 from the horizontal section 11 of the slide rail 1, so that the instability caused by the downward sliding of the inclined section 12 can be avoided, meanwhile, the inclined section 12 extends into the water, and the buoy can float in the accommodating cavity of the conveying device 2 under the action of buoyancy when entering the water so as to separate from the conveying device 2.

As an alternative embodiment, the angle of inclination of the inclined section 12 relative to the horizontal is between 30-70 degrees. When the inclination angle is small, the buoy in the water can be effectively prevented from being damaged by the operation of the ship engine, and therefore, the angle is preferably about 30 degrees.

Above all, considering that the conveying device 2 needs to come and go to the water surface frequently, the lower end or the side wall of the conveying device 2 is provided with a water permeable hole, so that water can conveniently flow into the accommodating cavity of the conveying device 2 or flow out of the accommodating cavity of the conveying device 2.

In order to control the movement of the conveying device 2 conveniently, an electric control device can be arranged to control the movement or control the movement in a manual pulling mode. When the control of the manpower is selected, one side provided with the conveying device 2 is provided with a stay wire, and a worker controls the position of the conveying device 2 on the sliding rail 1 by controlling the retraction of the stay wire.
