Description

Technical Field

[0001] The utility model relates to the technical field of ship maintenance, in particular to an environmentally friendly water platform. Background Art

[0002] The floating slipway is also called the floating work platform, which is mainly used for ship maintenance. In recent years, with the vigorous development of the world's shipping industry, the demand for various types of ships in the domestic and foreign markets has continued to increase. In order to keep the ship in good condition, it is necessary to regularly maintain and repair the ship during its service life, such as rust removal of the outer hull of the ship. At present, most medium and large ships use floating docks as the ship's water maintenance platform. The existing floating dock has a huge concave-shaped cabin with walls on both sides and open front and rear ends. It is a special trough-shaped flat-bottomed ship; the dock walls and dock bottom on both sides are box-shaped structures, which are divided into several closed compartments along the longitudinal and transverse directions. Some compartments are called water tanks, which are used to fill and drain water to make the dock sink. On the working deck (top surface of the dock bottom plate) of the floating dock, there are usually many piers densely arranged to support the ship to be repaired. Before the ship goes up to the pier, the floating dock sinks as a whole, and then the ship to be repaired is towed to the working deck of the floating dock, and then the floating dock is drained and floated to realize the ship's pier. The dirty oily water and powdery solid waste generated during ship maintenance usually need to be cleaned up, but in the existing floating dock structure, due to the flat bottom structure of its working deck and the many piers densely arranged on the working deck, it can usually only be cleaned manually, but it is difficult to clean it up. In this way, after the dock is launched, it will cause water pollution, which is poor in environmental protection and unfriendly to the environment.

[0003] Therefore, there is an urgent need to provide a new water slipway to be used as an water maintenance operation platform for ships, which is required to be able to collect and clean the dirty oily water and powdery solid waste generated during the ship maintenance process, so as to improve the overall environmental protection.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0031] It should be noted that the drawings are only used for illustrative purposes and represent only schematic diagrams rather than actual drawings, and should not be construed as limitations on the present invention. In order to better illustrate the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0032] See also Figure 1-11 An environmentally friendly water slipway comprises: a slipway body 1 and a ship landing assembly for moving a ship to be repaired 8 onto the slipway body 1. The slipway body 1 here refers to a working maintenance platform floating on the water surface, which is usually an integral buoyancy box structure, and a plurality of closed compartments are generally arranged inside it, so that the slipway body 1 floats on the water surface. The slipway body 1 can also carry a power source for navigation in the water. This part is an existing structure and will not be repeated here; the slipway body 1 has a ship carrying area 101 and a waste treatment cabin 102. The ship carrying area 101 here refers to the area on the top surface of the slipway body 1 for placing the ship to be repaired 8, which is usually in the width direction of the top surface of the slipway body 1. The sewage treatment tank 102 is in the middle position. The "waste" in the sewage treatment tank 102 refers to the dirty oily water and granular solid waste generated during the ship maintenance process. The sewage treatment tank 102 is used to collect the dirty oily water and granular solid waste. Of course, after collection, the sewage can be treated by sedimentation, filtration, separation and other methods. The treated water that meets the standards can be discharged directly, and the sewage and granular solid waste can be transferred to a special receiving ship. The sewage and granular solid waste treatment here are existing technologies and will not be repeated here; the working surface of the ship-carrying area 101 is a slope with a high head and a low tail. "High head and low tail" means that the bow end of the slipway is the head end, and the corresponding other end is the tail end, that is, the attached Figure 2The left side is low and the right side is high. Ships are usually moored upstream. The ship to be repaired 8 usually goes up the working platform from the tail end of the slipway. A water barrier 103 is provided at the tail end of the ship-carrying area 101 to intercept the dirty oil and water at the low point of the slope to prevent the dirty oil and water from flowing into the water when the ship-carrying area 101 is cleaned. A waste inlet 101a connected to the waste treatment cabin 102 is provided near the water barrier 103 on the ship-carrying area 101. The waste inlet 101a can be connected to the waste treatment cabin 102 through a pipeline. In the above structural design, the dirty oil and water and powdery solid waste scattered and accumulated in the ship-carrying area 101 after the ship is repaired are The waste oil and the like can be conveniently collected in the waste treatment cabin 102, and can be helpful in cleaning the ship-carrying area. Specifically, by making the working surface of the ship-carrying area 101 a slope with a high head and a low tail, and designing a water retaining belt, during the cleaning process, a high-pressure water gun and the like can be used for flushing to ensure that the cleaning is thorough. The dirty oil and water after flushing can be gathered in the waste treatment cabin 102 along the slope and will not flow into the water area, effectively reducing water pollution and improving the overall environmental protection. In addition, it is also beneficial to collect, process and discharge rainwater falling on the slipway, preventing the dirt on the slipway from being washed by rainwater and then directly discharged into the water area, thereby improving the overall environmental protection.

[0033] In this embodiment, the ship platform assembly includes: a floating ramp 2, preferably the floating ramp 2 also adopts a floating box structure, which is hinged to the tail end of the slipway body 1 in a slope-adjustable manner. In order to ensure the connection reliability of the floating ramp 2, the hinge points are designed as multiple groups along the width direction of the slipway body 1; a ship moving track I3, which is arranged on the floating ramp 2, and the ship moving track I3 is designed as at least two groups; a ship moving track II4, which is arranged in the ship carrying area 101 of the slipway body 1 and is arranged corresponding to the ship moving track I3, that is, when the slope of the floating ramp 2 is adjusted to a certain position, the alignment of the ship moving track I3 and the ship moving track II4 can be achieved. The installation of the track is an existing structure and will not be repeated here; a ship carrying vehicle 5, which can be driven along the ship moving area 101 Track Ⅰ3 is set on the ship moving track Ⅰ3 for walking. The ship-carrying vehicle 5 here refers to a vehicle body used to carry the ship to be repaired 8 and carry the ship to run on the slipway body 1. Usually, the ship-carrying vehicle 5 is a flatbed vehicle structure. The surface of the flatbed vehicle will be provided with a flexible material to increase friction, which can be driven by an additional traction device. Specifically, a winch 9 is set at the head end of the top surface of the slipway body 1. The winch pulls the ship-carrying vehicle 5 to run through a traction rope, such as a wire rope, and at the same time pulls the ship to be repaired 8 placed on the ship-carrying vehicle 5 to the ship carrying area 101. Here, the ship-carrying vehicle 5 and the ship moving track Ⅰ3 and the ship moving track Ⅱ4 are usually installed in a wheel-rail type. It should be noted that the ship to be repaired 8 is pulled by the ship-carrying vehicle 5. Going ashore is a conventional ship landing technology, which is used for ship landing on land. This part is an existing structure and will not be repeated here. The slope adjustment mechanism 6 is arranged on the slipway body 1 to adjust the slope of the floating ramp 2. Specifically, the slope adjustment mechanism 6 here is two groups of lifting equipment arranged on the lateral sides of the tail end of the slipway body 1, such as cranes, etc. The lifting equipment is connected to the lateral sides of the floating ramp 2 through a wire rope pulley group, and the floating ramp 2 is pulled by the lifting equipment to adjust the slope. This structure is different from the prior art in that the fixed ramp for ship landing on land is changed to an adjustable floating ramp. The advantage of the above structural design is that through the above structural form, the ship 8 to be repaired on the water can go up to the slipway When the ship is berthed, it is not necessary for the slipway to sink as a whole as the traditional floating dock, that is, the ship carrying area 101 of the slipway will not sink into the water, which can further improve the overall environmental protection, that is, even if there are some residual waste oil and water on the ship carrying area 101, it will not pollute the water area; at the same time, compared with the floating dock, such a structural form can reduce a large number of drainage equipment used for ballast water filling and drainage tanks, and the overall cost is reduced; at the same time, in the structural design, the ship-carrying vehicle 5 is directly used to complete the support of the ship to be repaired 8, which reduces a large number of piers and is more conducive to direct water cleaning of the ship carrying area 101; at the same time, such a structural form has a relatively short time for the ship to be repaired 8 to go on the platform, which can save a lot of time for filling and draining water;At the same time, since the ship carrying area 101 will not sink into the water during the whole process, the maintenance materials and tools prepared in advance in the ship carrying area 101 will not be soaked in water, and there is no need to remove the workpieces that cannot be soaked in water separately, which is conducive to saving construction time. ;

[0034] In this embodiment, there are multiple ship-carrying vehicles 5, which are connected to each other by chains 501. Multiple ship-carrying vehicles 5 are designed to ensure that during the process of the ship 8 to be repaired being put on the platform, each section of the ship 8 to be repaired can be effectively supported, and a chain groove 204 for chain stacking is provided on the floating ramp 2. Here, the chain groove 204 is correspondingly arranged next to the ship moving track Ⅰ3 and is arranged along the length direction of the ship moving track Ⅰ3. By designing the chain groove 204, the stacking of chains 501 between adjacent ship-carrying vehicles 5 can be avoided to affect the operation and folding of the ship-carrying vehicles 5.

[0035] In this embodiment, a chain conveyor roller 204a is provided in the chain groove 204. The structural form of the conveyor roller 204a is the prior art and will not be described here. The chain conveyor roller 204a is designed to overcome the lag of the iron chain due to friction, so that the chain can be gathered together with the ship-carrying vehicle at the bottom of the pontoon-shaped ramp, which is convenient for next use.

[0036] In this embodiment, the floating ramp 2 has a front section 201 and a rear section 202. The floating ramp 2 is a usual box structure. The front section 201 and the rear section 202 are also the lower section and the upper section. The slope of the rear section 202 is gentler than that of the front section 201. In this structural design, the lower part is relatively steep, so that after the repair ship is launched into the water, the ship-carrying vehicle can slide down and approach each other by its own weight after unloading; the slope of the upper section is relatively gentle, so as to be consistent with the slope of the inclined surface on the platform, and is mainly used for moving ships.

[0037] In this embodiment, a plurality of jacking mechanisms 101b are provided in the ship carrying area 101, and the plurality of jacking mechanisms 101b are used to jack up the ship holding vehicle 5 after it has been moved into position. Specifically, the jacking mechanism 101b here may adopt a jack, and the plurality of jacking mechanisms 101b here correspondingly jack up each ship holding vehicle 5. By designing the jacking mechanism 101b to jack up the ship holding vehicle 5, the ship to be repaired 8 is jacked up, which is beneficial to the maintenance of the bottom of the ship and the jacking is convenient. After the repair is completed, it is also beneficial to the cleaning of the ship carrying area 101 at a later time.

[0038] In this embodiment, a ballast water filling and discharge compartment 203 is provided in the floating ramp 2. The ballast water filling and discharge compartment 203 here can be filled and discharged by filling and discharging pumps, valves and other equipment. It is an existing structure and will not be described in detail here. In this structural design, by setting the ballast water filling and discharge compartment 203 in the floating ramp 2, it is beneficial to fill and discharge water through the ballast water filling and discharge compartment 203, and assist in adjusting the slope of the floating ramp 2.

[0039] In the present embodiment, ballast water regulating side tanks 104 are respectively provided on both sides of the rear end of the slipway body 1. The ballast water regulating side tanks 104 can be equipped with charging and drainage pumps, valves and other equipment to carry out charging and drainage in the tank. This part is an existing structure and will not be described in detail here. In this structural design, ballast water regulating side tanks 104 are respectively provided on both sides of the rear end of the slipway body 1, which is beneficial to the inclination angle of the slipway body 1 through the ballast water regulating side tanks 104, and is beneficial to the launching of the ship.

[0040] In the present embodiment, a movable enclosure shed 7 is also included in the ship carrying area 101 in a manner that it can move along the length direction of the slipway body 1. The movable enclosure shed 7 is used to complete the enclosure of the ship to be repaired 8 during segmented maintenance. The movable enclosure shed 7 itself is an existing structure. Preferably, retractable flexible roller blinds can be used around the movable enclosure shed 7. In this structural design, the movable enclosure shed 7 can be designed to prevent the escape of dust during ship maintenance and processing, which is conducive to further improving environmental protection.

[0041] In this embodiment, the water retaining belt 103 is arranged in a tooth shape, specifically, a triangular tooth shape, and waste inlet hatches 101a are provided at the positions close to the bottoms of each tooth in the tooth shape arrangement. This structural design is conducive to collecting the waste oil and water flowing down from the inclined surface of the ship carrying area 101 to the waste inlet hatches 101a at the bottom of the teeth. At the same time, designing multiple waste inlet hatches 101a can avoid the inefficiency of waste oil and water entering the cabin and avoid their escape.

[0042] See also Figure 7-11 The specific implementation process of the above-mentioned ship maintenance slipway and the upper and lower working platforms of the ship to be repaired is as follows: when the ship to be repaired is put on the platform: first, the floating ramp 2 is lowered to a certain slope, and then the ship to be repaired 8 is pressed on the ship-carrying vehicle 5 on the floating ramp 2 under the action of its own power or external traction force, and then the ship-carrying vehicle 5 runs along the ship moving track Ⅰ3, and drives the ship to be repaired 8 to move to the slipway together under the action of friction force. During the movement of the ship to be repaired 8, the slope of the floating ramp 2 is adjusted accordingly. Specifically, the floating ramp 2 is gradually pulled up until the floating ramp 2 is lifted. The rear section 202 of the ramp 2 is consistent with the slope of the inclined surface of the ship carrying area 101, and finally the ship to be repaired 8 is pulled to a specific maintenance area. After it is in place, in order to prevent the ship to be repaired 8 from sliding backward, the ship to be repaired 8 or the ship-carrying vehicle 5 can be limited. When the ship to be repaired is stepped down from the platform: the limit of the ship to be repaired 8 or the ship-carrying vehicle 5 is released, and the ship to be repaired 8 and the ship-carrying vehicle 5 automatically slide down the track into the water under the action of their own gravity. If necessary, the ballast water adjustment side tank 104 can be used to adjust the overall platform slope angle to ensure the smooth launching of the ship to be repaired 8.

[0043] The above-mentioned water slipway can not only be used for ship maintenance, but also has emergency rescue and combat readiness functions: the slipway is in a non-operating state, has a shallow draft, small resistance for anchoring or towing, a spacious working deck and strong carrying capacity, and can be used as an water emergency rescue platform; the liftable pontoon ramp can be used as a springboard to connect to the shore, and combat readiness vehicles can be driven onto the slipway and carried to the destination.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present utility model and are not intended to limit it. Although the present utility model has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present utility model, which should be included in the scope of the claims of the present utility model.
