Technical Field

[0001] The utility model belongs to the technical field of supporting equipment for floating docks, and in particular relates to a water mist spraying device for floating docks. Background Art

[0002] A floating dock is a highly flexible water engineering vessel that plays multiple roles in ship repair, construction and even salvage. Its operating principle is similar to that of a submarine, which can sink and float by adjusting the amount of water in the water tank. When a ship needs to be repaired, the floating dock sinks, and the ship enters and then drains and floats up, lifting the ship out of the water for dry dock operations. In addition, it can also help deep-draft ships pass through shallow waters and perform offshore platform support and shipwreck salvage tasks. As an important shipbuilding and repair facility, the floating dock is crucial to promoting the development of the global shipping and offshore engineering industries. It can handle large offshore structures including 10,000-ton tankers and container ships, demonstrating extremely high engineering value and strategic significance.

[0003] In the process of repairing ships on floating docks, the hull needs to be maintained, performance maintained, inspected and repaired. In this process, sandblasting dust, welding dust and grinding dust will be generated. The presence of these dusts will cause the surface of the hull to be contaminated and cause air pollution during the maintenance of the hull by the floating dock.

[0026] In the present utility model, if Figure 1-Figure 5As shown, a floating dock water mist spraying device is provided, comprising: a floating dock body 1, one side of the floating dock body 1 is rotatably connected to two sky bridges 101 through a hinge; a bracket 2, the bracket 2 is arranged on the top of the sky bridge 101, and a nozzle 3 is arranged on one side of the floating dock body 1 and the bracket 2; a nozzle 305, the nozzle 305 is opened at the bottom of the nozzle 3, and is used to form water mist to spray the surface of the hull.

[0027] During use, the hull needs to pass under the overpass 101 and enter the floating dock body 1. The water flow can be guided to the position of the nozzle 305 through the nozzle 3. At this time, the passing water flow can be pressurized into water mist and sprayed downward through the nozzle 305. During the spraying process, the surface of the hull is wetted, dust is reduced and maintained.

[0028] Among them, the nozzle 3 is divided into a right dock wall spray pipe 301 and a bridge spray pipe 302. The right dock wall spray pipe 301 is arranged on one side of the floating dock body 1, and the bridge spray pipe 302 is suspended on the top of multiple brackets 2. A lap pipe 303 is provided between the right dock wall spray pipe 301 and the bridge spray pipe 302. During use, the distributed design enables the right dock wall spray pipe 301 to form water mist on one side of the floating dock body 1. During the grinding and maintenance of the hull, some lightweight parts need to be disassembled separately for comprehensive grinding and rust removal. When grinding some lightweight parts and parts, the lightweight components can be moved to the bottom of the right dock wall spray pipe 301 of the main body 1 for grinding, so as to use the water mist formed under the right dock wall spray pipe 301 to reduce and prevent dust generated during the grinding process and prevent dust from escaping.

[0029] Among them, the spacing between multiple nozzles 305 is 500 mm. Using multiple equidistantly arranged nozzles 305 can make the connection and formation of water mist more stable, so that the water mist can be evenly sprayed on the surface of the hull, thereby improving the integrity of spraying and dust reduction.

[0030] Among them, a plurality of welding seats 304 are provided at the bottom of the nozzle 3, and the spacing between the plurality of welding seats 304 is 250 mm, and the nozzle 3 is arranged on the welding seat 304. During use, the welding seat 304 is used as the base of the nozzle 3 to assist the use of the nozzle 3, and the use of the welding seat 304 with a shorter spacing can reserve a spare welding seat 304 between the two nozzles 305. When a nozzle 305 or a welding seat 304 is damaged, the reserved welding seat 304 can be directly used for coordinated spraying, thereby improving the maintenance convenience of the device.

[0031] Among them, a plurality of support rods 202 are provided at the upper end of the bracket 2, and the plurality of support rods 202 are distributed in a triangular structure. During use, the triangular structure formed by the plurality of support rods 202 can make the bracket 2 more stable and prevent the bracket 2 from becoming loose as a whole, thereby improving the stability of the device.

[0032] Among them, a connection port 307 is provided at one end of the nozzle 3 facing the floating dock body 1, and a pressure gauge 306 is provided at the connection between the connection port 307 and the nozzle 3. When water is supplied, the inside of the nozzle 3 is filled with water through the connection port 307. At this time, the water pressure is monitored by the pressure gauge 306, which can assist the user to better control the water pressure of the spray.

[0033] Among them, a hanging position 201 is provided on one side of the top of the bracket 2, and the nozzle 3 passes through the hanging position 201 and is connected to the bracket 2. The nozzle 3 is suspended by using the hanging position 201. When installing the nozzle 3, the staff only needs to insert the nozzle 3 into multiple hanging positions 201 to complete the installation, thereby improving the installation convenience of the nozzle 3.

[0034] Among them, inclined traction ropes 203 are provided on both sides of the bracket 2, and the bottom of the traction rope 203 is connected to the overpass 101. During use, the two traction ropes 203 are used to laterally fix the bracket 2. When facing strong winds and traction forces, the bracket 2 can be corrected to prevent the bracket 2 from deviating and collapsing.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
