[0003] In some coastal areas, due to limited land resources and multiple factors such as topography, coastline protection or ecologically sensitive areas, the layout of storage tanks is greatly restricted. When the volume of the storage tank is too large, it will further increase the floor space. On ships, the amount of domestic sewage and industrial sewage generated is usually large, and sufficient buffer time is required for treatment or transfer. However, large storage tanks are not convenient for later transfer and treatment, and the space on the ship is limited. Larger storage tanks will result in smaller space for activities on board. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the sewage storage tank in the prior art occupies a large area. Faced with the current situation of limited land resources in coastal areas, the layout of the storage tank is greatly restricted. On ships, the amount of domestic sewage and industrial sewage generated is usually large, and the large volume of the storage tank is not convenient for subsequent transfer and treatment.

[0038] The present invention is further described in detail below in conjunction with the accompanying drawings:

[0039] See also Figure 1 The embodiment of the present invention discloses a marine sewage storage bag, which solves the problem that the sewage storage tank in the prior art occupies a large area. Faced with the current situation of limited land resources in coastal areas, the layout of the storage tank is greatly restricted. On ships, the amount of domestic sewage and industrial sewage generated is usually large, and the large storage tank is not convenient for later transfer and treatment. In addition, the space on the ship is limited, and a large-capacity storage tank will lead to a problem of smaller activity space on the ship. Based on this problem, the device disclosed in this embodiment applies the buoyancy principle to put the water bag into the water to store sewage, reducing the weight of the container itself. At the same time, the buoyancy principle offsets the gravity of the stored sewage, achieving a balance between buoyancy and weight, and can store a large amount of sewage.

[0040] Specifically, the sewage storage bag disclosed in the embodiment of the present invention includes the following structure:

[0041] Example 1

[0042] The present embodiment discloses an offshore sewage storage bag, including a water bag 3, wherein the water bag 3 includes a first cavity, wherein the outer side of the first cavity wraps a second cavity; a sewage inlet 2 is provided on the first cavity, and an air inlet is provided on the second cavity; a connecting anchor unit is provided at the lower end of the second cavity, and the connecting anchor unit can sink into the water.

[0043] Furthermore, in an embodiment of the present invention, the first cavity and the second cavity are two independent cavities, wherein the first cavity is mainly used to store sewage, and the second cavity is mainly used to store gas. A sewage inlet 2 is opened on the first cavity, and a sewage pipe 1 is connected at the sewage inlet 2 to discharge external sewage 7 into the sewage storage bag. A sewage drain outlet can also be opened on the first cavity to facilitate the discharge of sewage when the sewage is treated later.

[0044] Similarly, an exhaust port is also provided on the second cavity. The exhaust port and the air inlet cooperate to adjust the air pressure inside the second cavity in real time. Specifically, when inflating when needed, an appropriate amount of gas can be filled into the second cavity to increase the buoyancy of the sewage storage bag and keep it stable on the water surface. When there is too much gas and the buoyancy needs to be reduced, the exhaust port is opened to release some of the gas, which helps the storage bag maintain the best working condition under different water depths and sea conditions.

[0045] Furthermore, in an embodiment of the present invention, the first cavity is made of a material that is corrosion-resistant, wear-resistant and has good sealing properties, such as a polymer synthetic rubber, such as butyl rubber or chloroprene rubber or reinforced PVC material, to prevent sewage leakage and withstand a certain internal pressure.

[0046] Furthermore, in an embodiment of the present invention, the second cavity is made of a composite material of high-strength synthetic fiber (such as nylon or polyester fiber) and rubber to prevent external physical damage and erosion by the marine environment, thereby improving durability of use.

[0047] Furthermore, in the embodiment of the present invention, the connecting anchor unit enables the sewage storage bag to be relatively stably fixed at a designated position to prevent drifting or capsizing due to natural factors such as wind and waves.

[0048] In the present embodiment, the sewage storage bag has a double-layer cavity structure, the first cavity is specifically used to store sewage, and the second cavity controls the buoyancy and sedimentation depth by adjusting the air volume. The two-layer cavity is independent of each other and has a compact structure and a small overall volume, so that the sewage storage bag can utilize the offshore space for storage and reduce the footprint. The connecting anchor unit can ensure the relative stability of the position of the sewage storage bag when stored at sea, and in subsequent transportation and transfer, since the sewage storage bag has a small footprint and self-floating ability, it can be transferred by tugboat or other marine transportation tools. Under the action of seawater buoyancy, the transfer is more convenient, and the sewage storage bag does not require complex infrastructure or fixed facilities, saving disassembly and installation time, and has higher flexibility. The sewage storage bag disclosed in the present invention can be quickly moved to a designated location for deployment according to changes in the offshore operating area or the needs of sewage treatment tasks, thereby improving the flexibility and response speed of sewage treatment.

[0051] Furthermore, in the embodiment of the present invention, the rope 4 can be made of nylon or polyester fiber. The rope 4 made of this material has high strength and high corrosion resistance, ensuring that the rope 4 will not break or wear during long-term use in the marine environment.

[0052] Furthermore, the specific connection method of the anchor 5 and the rope 4 in the embodiment of the present invention is:

[0053] A metal ring is installed at the end of the rope 4, and a connecting hole corresponding to the metal ring is opened on the fixing anchor 5, and the metal ring can be fixedly connected to the connecting hole.

[0054] Furthermore, in the embodiment of the present invention, the length of the rope 4 is not limited, and the length of the rope 4 can be adjusted according to different water depths and seabed topography.

[0055] Furthermore, in the embodiment of the present invention, the coordination of the rope 4 and the fixed anchor 5 enhances the stability of the entire sewage storage bag at sea. When encountering strong winds and waves, the sewage storage bag can also maintain a relatively stable posture to prevent safety hazards caused by shaking or drifting, ensuring the safety and reliability of the sewage storage process. The fixed anchor 5, as a fixed point on the seabed, provides a clear position reference for the sewage storage bag. When the storage bag needs to be transferred or recovered, it can be easily positioned and moved by pulling the rope 4, reducing the difficulty of finding and positioning the storage bag and improving the operation efficiency.

[0058] Furthermore, in the embodiment of the present invention, the connection method of the connecting buckle 8 and the rope 4 is that a metal hole is opened on the connecting buckle 8, and the rope 4 is fixed after passing through the metal hole.

[0059] Furthermore, in the embodiment of the present invention, a connecting hole is opened on the side wall of the second cavity, and the connecting buckle 8 passes through the connecting hole to be connected to the second cavity.

[0060] Furthermore, in the embodiment of the present invention, the surface of the connecting buckle 8 can be subjected to anti-corrosion treatment, such as galvanizing, spraying anti-corrosion paint, etc., to enhance its corrosion resistance.

[0061] Furthermore, in the embodiment of the present invention, the connecting buckles 8 are distributed at intervals along the outer side wall of the second cavity, and the number of the connecting buckles 8 can be adjusted according to demand.

[0062] Furthermore, in the embodiment of the present invention, the connecting buckle 8, as the connection point between the rope 4 and the outer side wall of the second cavity, can withstand large tension and shear force. The setting of the connecting buckle 8 enhances the strength of the entire connection structure, ensuring that the rope 4 will not break or loosen due to excessive force under severe sea conditions, thereby ensuring the stability and safety of the sewage storage bag. In addition, the connecting buckle 8 makes disassembly and installation more convenient and improves installation efficiency.

[0065] Furthermore, in the embodiment of the present invention, the fiber layer can be bonded to the inner wall of the first cavity by bonding. In addition, the fiber layer and the first cavity can be an integrated structure and can be integrally formed during processing.

[0066] Furthermore, in the embodiment of the present invention, the fiber layer has high tensile strength and tear resistance, which can effectively enhance the overall structural strength of the first cavity, so that it can withstand greater internal pressure and external impact. In addition, the particles and impurities in the sewage may cause wear on the inner wall of the sewage storage capsule, and the fiber layer can effectively resist such wear and tear, thereby extending the service life of the storage capsule.

[0068] The present embodiment discloses an offshore sewage storage bag, including a water bag 3, wherein the water bag 3 includes a first cavity, wherein the outer side of the first cavity wraps a second cavity; a sewage inlet 2 is provided on the first cavity, and an air inlet is provided on the second cavity; a connecting anchor unit is provided at the lower end of the second cavity, wherein the connecting anchor unit can be sunk into water, and a plurality of partition layers are provided inside the first cavity, wherein the partition layers are used to partition the interior of the first cavity into a plurality of independent sub-chambers, and a water inlet is provided on each sub-chamber.

[0069] Furthermore, in the embodiment of the present invention, by dividing the large cavity into multiple sub-chambers, the storage space can be utilized more effectively, and the sewage storage capacity of each sub-chamber can be flexibly allocated according to actual needs. In this embodiment, a corresponding sewage outlet is opened on each sub-chamber, and each sub-chamber can be monitored, cleaned and maintained separately, reducing the difficulty and cost of overall maintenance.

[0070] Furthermore, in the embodiment of the present invention, the specific division method of the segmentation layer is:

[0071] Split vertically:

[0072] Each partition layer divides the first cavity along the vertical direction. The partition layer is perpendicular to the bottom and the top of the first cavity, and divides the first cavity into a plurality of sub-chambers of equal or unequal heights in the vertical direction, thereby making full use of the vertical space of the first cavity.

[0073] Split horizontally:

[0074] The partition layer can also be used to partition along the horizontal direction inside the first cavity to form parallel sub-chambers.

[0075] Furthermore, in the embodiment of the present invention, the provision of the partition layer can increase the structural strength of the first cavity, enabling it to withstand greater internal pressure and external impact. The partition layer can also serve as a supporting structure to disperse and balance the pressure distribution inside the first cavity to prevent rupture or damage caused by excessive local pressure. The independent sub-chamber design can reduce the risk of sewage leakage. Even if a sub-chamber leaks, measures can be taken quickly to seal and repair it to prevent the leakage from spreading to the entire first cavity.
