[0002] In the existing designs of small cruise ships and yachts, like large ships, black water tanks are also designed to collect black water sewage.

[0003] The current problem is:

[0004] First, the number of toilets on small cruise ships or yachts is limited, so the amount of black water collected is relatively small, and the traditional black water tank design is often too large, resulting in low actual utilization rate and taking up valuable hull space;

[0005] Secondly, these black water tanks are usually made of steel, which is not only heavy but also expensive;

[0006] Furthermore, the discharge system of the black water tank also needs to be equipped with a dedicated sewage pump to discharge the sewage to the onshore treatment facilities or receiving ships, which not only increases the cost of additional equipment, but also requires the cooperation of the dock or receiving ship, increasing time and economic costs;

[0007] Finally, the internal structure of traditional black water tanks is difficult to clean, and long-term accumulation may lead to odor pollution and other hygiene problems. Summary of the invention

[0008] The purpose of the present invention is to provide a sewage tank device for a small cruise ship, which is used to replace the black water tank in the prior art to receive and collect black water, thereby overcoming many disadvantages of the black water tank design.

[0024] Figure 1 The figure is a schematic structural diagram of a sewage tank device for a small cruise ship according to the present invention. DETAILED DESCRIPTION

[0025] The present invention will be further described below with specific embodiments:

[0026] The present embodiment provides a sewage tank device for a small cruise ship, which is specially designed for small cruise ships. The sewage tank device is arranged at the sewage outlet of the cruise ship's sewage system (black water sewage system or gray water sewage system), and its function is to collect sewage (black water or gray water) discharged from the sewage outlet.

[0027] See also Figure 1 , specifically,

[0028] The sewage tank device mainly comprises a tank body 1 and an integrated tank cover 2 .

[0029] The tank body 1 is made of high-density polyethylene or polypropylene by injection molding. The capacity of the tank body 1 can be set to 30-200L.

[0030] The integrated tank cover 2 can be hermetically covered on the tank body 1, thereby sealing the tank body 1. It should be noted that the integrated tank cover 2 and the tank body 1 are firmly connected together by "covering".

[0031] More specifically, in this embodiment, the integrated tank cover 2 and the tank body 1 are connected by a flange clamp in the prior art; in other embodiments, a screw cap or a quick connector may be used to connect them. The same connection method is also applied to the ordinary tank cover mentioned later.

[0032] The integrated tank cover 2 is integrated with a sewage receiving pipe opening 3 and an exhaust pipe opening 4 , and both of the two pipe openings are connected to the inner and outer sides of the integrated tank cover 2 .

[0033] The sewage receiving pipe port 3 is used to communicate with the sewage discharge pipe port of the original sewage system of the cruise ship to receive the sewage discharged from the sewage system into the tank body 1.

[0034] In order to facilitate the connection between the sewage pipe opening 3 and the "sewage discharge pipe opening of the sewage system", a quick connection mechanism is provided between the two. Specifically, both are provided with matching quick pipe joints, so that the two can be conveniently and quickly connected together.

[0035] The exhaust pipe port 4 is used to communicate with the waste gas exhaust pipeline, and is connected to the atmosphere through the waste gas exhaust pipeline to discharge the gas that needs to be discharged when "the waste water discharged from the sewage system enters the tank body 1".

[0036] It should be noted that the waste gas exhaust pipeline is specially configured on the cruise ship for the sewage tank device of this embodiment. The specific direction of the waste gas exhaust pipeline is determined according to the specific position of the sewage tank device. It is as straight and upward as possible. One end of the pipe is connected to the exhaust pipe 4 of the sewage tank device, and the other end is placed at the highest possible point in the entire ship and connected to the atmosphere to avoid the impact of odor on the cabin environment.

[0037] In addition, a liquid level detector 5 is also provided on the integrated tank cover 2, and the detection end of the liquid level detector 5 extends into the inner side of the tank body 1, and the detection signal of the liquid level detector 5 is connected to the original alarm system of the cruise ship. When the sewage water level in the tank body 1 reaches the detection end of the liquid level detector 5, the liquid level detector 5 sends a corresponding detection signal to the alarm system, and the alarm system sends an alarm signal based on the detection signal of the liquid level detector 5.

[0038] In summary, when the liquid level detector 5 detects that the sewage level in the tank body 1 reaches a specified level, the alarm system of the cruise ship will send out an alarm signal to remind the crew on board to update the tank body 1 .

[0039] In this embodiment, for the sewage tank device, one or more spare tank bodies 1 are provided on the cruise ship. When the alarm system of the cruise ship sends an alarm signal, the spare tank body 1 is used to update the tank body 1 on the sewage tank device. The spare tank body 1 can provide redundancy for the black water collection capacity of the cruise ship.

[0040] In addition, in order to prevent the sewage in the updated tank body 1 from being directly exposed to the air and thus causing air pollution, each tank body 1 is configured with a common tank cover, which is covered on the updated tank body 1 to prevent pollution.

[0041] The specific working principle of the sewage tank device in this embodiment is as follows:

[0042] The sewage discharged from the sewage system's sewage outlet enters the tank body 1 through the sewage outlet 3. During this process, the excess gas in the tank body 1 is discharged from the exhaust outlet 4 and discharged into the atmosphere through the sewage exhaust pipeline of the cruise ship.

[0043] When the sewage water level in the tank body 1 reaches the detection end of the liquid level detector 5 , the alarm system of the cruise ship is triggered to sound an alarm, reminding the crew to update the tank body 1 .

[0044] The tank body 1 is then covered with an ordinary tank cover. After the cruise ship berths at the pier, the tank body 1 filled with sewage is transferred to a special sewage treatment site on the shore for subsequent harmless treatment.

[0045] In this embodiment, the sewage tank device is used to replace the black water tank of the prior art to receive and collect black water. The advantages of this are:

[0046] 1) Compared with the traditional black water tank, the sewage tank device occupies less space, does not require complex hull design, and saves hull space;

[0047] 2) The sewage tank device is compact and light, thus reducing the weight of the hull;

[0048] 3) There is no need for the sewage pump configured in the traditional black water tank design, nor does it require the cooperation of the dock or receiving ship, thus saving time and economic costs;

[0049] 4) The tank body 1 is made of high-density polyethylene or polypropylene by injection molding, which is environmentally friendly and durable, with a smooth inner wall and easy to clean.

[0050] In addition, the sewage tank device of this embodiment has the following derivative advantages:

[0051] The sewage tank device has a light weight, is easy to transport, and saves space and costs;

[0052] The number of spare tank bodies 1 is arbitrary, which can flexibly cope with various shipboard working conditions;

[0053] No sewage discharge pipeline is required, which reduces the cost of equipment and pipelines;

[0054] No need for cooperation from emission receiving sites, thus eliminating emission restrictions;

[0055] No emission reception cost, which reduces emission costs.

[0056] It should be noted that the sewage tank device of this embodiment can be used in both black water sewage system and grey water sewage system, as long as the sewage tank device is installed at the sewage outlet.

[0057] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
