Description

Technical Field

[0001] The invention relates to a flotation aid device, in particular to a ship launching flotation aid device, belonging to the technical field of ship launching. Background Art

[0002] With the rapid development of the shipbuilding industry, my country's shipbuilding capacity is getting stronger and stronger, and there are more and more large ships. The first launch of a ship from land is a dangerous challenge. Shipyards can choose a variety of launching methods and facilities according to their own conditions and production requirements. Mechanized launching requires the use of slides, tracks and traction components. According to the different postures of the ship entering the water, it can be divided into longitudinal entry and transverse entry. Both launching methods are to place the ship on the slide, use the traction component to pull the ship and slide it forward. The track is usually tilted downward, and the ship slides into the water under the action of traction and deadweight. To ensure the safety of the ship entering the water, the track needs to extend below the horizontal plane.

[0003] When a ship enters the water, it is easy to capsize or be smashed. A launching flotation device can be set up to support and cushion the ship. However, most of the existing flotation devices are flotation boards. The ship is towed onto the flotation board and falls into the river channel with the flotation board. If the ship is launched vertically, the bow or stern will rush into the river channel first when the hull slides down the slope of the river bank due to its own weight. Since the existing flotation board can only provide a certain buoyancy, the impact force on the bow or stern is too large, and it is very likely to directly contact the bottom of the river channel, causing damage to the hull, and in severe cases, the hull may capsize.

[0017] The present invention provides a ship launching buoyancy aid device, which has the following beneficial effects:

[0018] 1. The ship launching buoyancy aid device places the hull on the top of the fixed frame, so that the multiple first buoy hulls are supported and buffered, and the hull rolls on the top of the multiple first buoys, so that the bow fits with the front baffle, and the side support plate and the front baffle support the hull, thereby improving the stability of the hull. At the same time, the buried pipe is buried in the slope for fixing, and the staff uses a sledgehammer to knock the moving block, and the moving block slides inside the slide rail, so that the moving block drives the pull rope to move inside the buried pipe, and when the pull rope moves, the slide plate is pulled to slide inside the sliding sleeve, so that the slide plate compresses the reset spring, and the slide plate slides inside the sliding sleeve, so that the slide plate and the fixed plate are disconnected from the docking, so that the fixed plate releases the limit, and the hull and the fixed frame lose the limit, and the moving sleeve is driven by the weight of the hull and the fixed frame to slide on the outside of the guide rail, so that the fixed frame and the hull slide underwater, which is convenient for guiding the hull into the water and improving the stability of the hull when launching;

[0019] 2. The ship launching buoyancy aid device lifts the portion where the support plate is connected to the fixed cylinder to maintain communication with the water flow inside the river channel, so that the water flow inside the river channel flows into the fixed cylinder from the filter screen and is poured into the water storage cylinder. The fixed plate is driven to move by the fixed frame when it moves, so that the fixed plate drives the two sliding rods to move, and drives the two sliding rods and the two top water plates to move, so that the two top water plates slide inside the two water storage cylinders, and at the same time, the sliding rod slides inside the front connecting plate. When the top water plate moves inside the water storage cylinder, it pushes the water flow inside the water storage cylinder to move, so that the water flow flows inside the rear connecting plate, and the water flows out from multiple water holes inside the rear connecting plate. The water holes transmit water flow to form a damping effect, thereby buffering the top water plate, thereby improving the buffering stability of the top water plate, so that when the fixing frame and the hull slide down, the fixing frame is buffered, the impact force on the hull is reduced, and the safety of the hull launching is ensured, and the water flow is circulated through the guide pipe inside the compression sleeve. The guide pipe is larger at the top and smaller at the bottom, so that the guide pipe compresses the water flow and buffers the water flow. When water flows out from the compression sleeve, it drives the impeller to rotate, and the impeller drives the rotating shaft to rotate, so that the rotating shaft drives the scraper to rotate when it rotates, so as to clean the surface of the filter screen, clean the impurities on the surface of the filter screen, prevent the bottom of the fixed cylinder from being blocked, and facilitate dredging;

[0020] 3. The ship launching buoyancy aid device makes the fixed frame and the hull float, and at the same time, the multiple first buoys provide buoyancy to the bow to prevent the bow from sinking, reduce the impact force on the hull, and improve safety. At the same time, when the hull presses down on the fixed frame and the side support plate, the side support plate drives the connecting rod and the sleeve to descend, and the second buoy is provided with buoyancy to improve stability. The buoyancy of the rising second buoy and the gravity of the downward pressure of the fixed frame make the rotating plate drive the pushing plate to move, so that the pushing plate pushes the moving rod to slide, and the moving rod pushes the piston plate to move inside the sleeve. The buffer inside the sleeve passes through the multiple through holes inside the piston plate to form a damping effect. At the same time, the sleeve compresses the first spring to improve the buffering effect and increase stability. At the same time, when the swing arm swings, the guide rod slides inside the connecting rod to compress the second spring, further buffer the swing arm, support the multiple second buoys, and make the multiple second buoys open outward when falling into the water, thereby improving the stability of the fixed frame.

The bottom ends of the two fixed cylinders 13 are fixedly connected to support plates 20, and the insides of the two support plates 20 are fixedly connected to filter screens 22. The two rotating shafts 18 respectively penetrate the two filter screens 22 and are rotatably connected to the two filter screens 22. The bottom ends of the two rotating shafts 18 are fixedly connected to scrapers 23, and the two scrapers 23 are respectively fitted with the two filter screens 22. When the rotating shaft 18 rotates, the scrapers 23 are driven to rotate, so that the scrapers 23 clean the surface of the filter screen 22. The two fixed cylinders 13 are respectively fixedly connected to the two support plates 20 with support arms 21. The two support plates 20 are buried at the bottom of the shore slope to support the fixed cylinder 13.

[0037] Specifically, the hull is placed on the top of the fixing frame 1, so that the multiple first pontoons 2 support and cushion the hull, and the hull rolls on the top of the multiple first pontoons 2, so that the bow fits with the front baffle 4, and the side support plate 3 and the front baffle 4 support the hull, thereby improving the stability of the hull. At the same time, the buried pipe 38 is buried in the slope and fixed. The staff uses a sledgehammer to knock the moving block 44 and make the moving block 44 slide inside the slide rail 43, so that the moving block 44 drives the pull rope 42 to move inside the buried pipe 38. When the pull rope 42 moves, it pulls the slide plate 40 to slide inside the sliding sleeve 39, so that the slide plate 40 compresses the return spring 41.

[0040] One side of the two side support plates 3 is fixedly connected to a vertical plate 34, one side of the vertical plate 34 is hinged with a connecting rod 35, the bottom end of the connecting rod 35 is rotatably connected to a guide rod 36, a sliding groove is provided inside the swing rod 25, the guide rod 36 passes through the internal sliding groove of the connecting rod 35 and is slidably connected to the connecting rod 35, so that the connecting rod 35 and the guide rod 36 guide the swing rod 25, and a second spring 37 is provided inside the sliding groove of the swing rod 25, and the two ends of the second spring 37 are fixedly connected to the guide rod 36 and the swing rod 25 respectively, and the guide rod 36 is buffered by the second spring 37.
