Description

Technical Field

[0001] The utility model relates to the technical field of water environment treatment, in particular to a red tide treatment ship. Background Art

[0002] With the continued development and utilization of offshore waters, large amounts of industrial wastewater and domestic sewage are flowing into the coastal waters, causing increasingly serious red tide pollution. Therefore, society urgently needs a feasible and effective method to control red tide pollution. Currently, the process of combating red tides involves spraying a water suspension of clay into the sea—a mixture of seawater and clay. This mixture combines with algae, preventing them from photosynthesizing and causing them to sink to the seabed.

[0003] The current application technology directly impacts the efficiency of modified clay methods for eliminating red tide organisms and is a significant factor limiting their effectiveness. Existing control technologies often encounter the following problems: clay has a high specific gravity and easily clumps during storage, causing sedimentation; uneven mixing prevents uniform spraying; the spraying range is small, requiring control vessels to make multiple round trips to achieve full coverage; and the limited spraying range prevents coverage near the coast or in areas beyond the reach of control vessels. Therefore, this utility model proposes a new red tide control vessel to address these existing issues. Utility Model Content

[0023] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0024] like Figure 1-Figure 3 As shown, the present invention is applied to red tide control. Currently, a common method of red tide control is to evenly mix clay with seawater and then spray it onto the water surface. This method utilizes the flocculation effect of clay minerals on red tide organisms and the destruction of red tide organism cells by aluminum ions in the clay minerals. The red tide control vessel in the present invention uses a mixing system to achieve mixing of clay and seawater; and a spraying system to evenly spray the mixed solution onto the water surface.

[0025] Specifically, a red tide control vessel comprises a hull 1, a mixing system 2, and a spraying system 3. The spraying system 3 is located at the stern of the hull 1, and the mixing system 2 is located within the cabin 11 of the hull 1. A clay tank is provided on the deck of the hull 1 to store clay raw materials. The hull 1 uses a hybrid propulsion system, which ensures pure electric and silent operation, reducing noise pollution in offshore areas, while also allowing for long-term diesel operation.

[0026] The mixing system 2 includes a mixing chamber 21, which is provided with a stirring device 22. A feeding port 211 is provided at the upper end of the mixing chamber 21. The feeding port 211 is provided at the upper end of the mixing chamber 21 and extends upward to the deck. The feeding port 211 can be located adjacent to the clay tank, facilitating the timely addition of clay when feeding is required. The mixing chamber 21 is connected to a water inlet 24 via a first pipe 23, and the water inlet 24 is provided at the bottom of the hull 1. A separate water suction pump (not shown) can be provided on the first pipe 23 to supply water to the mixing chamber 21, or a generator set within the hull 1 can be used to drive the water suction pump for water intake.

[0027] The mixing chamber 21 is located in the center of the cabin's horizontal direction. The mixing device 22 is provided with at least two devices, each comprising a mixing motor 221, a mixing shaft 222, and a mixing blade 223 connected to the mixing shaft 222. The mixing motor 221 is located at the top of the mixing chamber 21. The upper end of the mixing shaft 222 is connected to the mixing motor 221, and the lower end is located within the mixing chamber 21. The mixing blade 223 is connected to the mixing shaft 222. In this embodiment, clay has a water-absorbing property and will stick together and clump after long-term storage. The provision of two mixing devices 22 can ensure that the clay is fully dissolved in seawater, thereby preventing sedimentation and blockage.

[0028] The spraying system 3 includes a pump 31, a spraying device 32 and an injection device 33. The pump 31 is arranged in the cabin and connected to the mixing chamber 21; the injection device 33 is arranged at the tail end of the hull 1, and the spraying device 32 is arranged on both sides of the tail end of the hull 1; the spraying device 32 and the injection device 33 are connected to the pump 31, and the pump 31 can suck the liquid in the mixing chamber 21 and discharge it through the spraying device 32 and the injection device 33.

[0029] The spraying device 32 includes a second pipe 321, one end of which is connected to the pump 31 and rotatably connected to the hull 1; the other end extends outward from the hull 1, suspended in mid-air. Multiple nozzles 322 are mounted on the second pipe 321, and the pump 31 draws liquid and sprays it through the nozzles 322. A towing rope 323 is connected to the center of the second pipe 321, and the end of the towing rope 323, away from the second pipe 321, is connected to the hull 1. The spraying device 33 includes multiple spray guns 331 located at the stern of the hull, with adjustable spray angles.

[0030] In this embodiment, when operating in open waters, while the treatment vessel is advancing, the spraying device 32 sprays on both sides of the hull 1, and the injection device 33 sprays at the stern of the hull 1. The spraying area of the mixed liquid can cover the entire range of the treatment vessel when it is advancing. When operating in areas such as ports and near the coast where it is difficult for the treatment vessel to approach, the operation area can be sprayed by the injection device 33. The connection between the spray gun 331 and the stern can be set to a rotating connection so that the injection angle of the spray gun 331 can be adjusted to ensure full coverage of the operation area. The second pipe 321 is rotatably connected to the hull 1. When not in operation, the second pipe 321 can be rotated and recovered to fit the side of the hull 1, so that the treatment vessel can navigate or dock in a limited area. The length of the second pipe 321 can be set to be longer. The setting of the towing rope 323 can prevent the second pipe 321 from bending due to gravity during operation, and also facilitates the recovery or deployment of the second pipe 321.
