Description

Technical Field

[0001] The invention relates to an offshore replenishment receiving device, in particular to a liquid cargo reverse transmission replenishment receiving device and method. Background Art

[0002] Replenishment at sea is an important way to ensure that large ships can sail into the deep sea and complete ocean-going missions. For large ships, a large amount of support materials such as fuel, fresh water, equipment parts, food, and medicine are important supports for maintaining their ocean-going capabilities during ocean-going voyages. Their own supply receiving devices are important support equipment for achieving replenishment at sea, which determines their ocean-going capabilities.

[0003] The daily training of the navy at sea is becoming increasingly heavy, and the training of far sea operations is becoming more and more normalized. The frequency of maritime replenishment is becoming more and more frequent. Under the premise that the number of supply ships is difficult to increase rapidly in a short period of time, the technology of modifying and refitting maritime civilian transport ships will play an increasingly important role. At the same time, in order to adapt to the characteristics of diversified combat styles, multi-dimensional combat space, and complex combat forces in the future, the maritime support and guarantee fleet dominated by civilian ships is mobilized, and the maritime supply and guarantee mode is expanded to a secondary or tertiary guarantee mode, among which the supply ship modified from a civilian ship is one of the main components of the guarantee fleet.

[0004] Compared with conventional forward supply, the reverse transmission of liquid cargo by a supply ship generally relies on other supply ships or can only be completed at the dock. However, due to the small number of supply ships or the long distance from the dock, the existing liquid cargo reverse supply obviously cannot meet the relevant needs. This requires the development of a set of liquid cargo reverse transmission supply receiving devices. Summary of the invention

[0005] The present invention is to provide a liquid cargo reverse transmission replenishment receiving device and method, which are used to solve the following technical problems (purposes of the invention):

[0006] 1. With the help of supply ships or civilian oil tankers, the liquid cargo of the supply ship can be reversely transmitted and supplied to meet the liquid cargo supply needs of the supply ship;

[0007] 2. Using existing pelican hooks, shackles and other equipment, using CRJ150 quick connectors, double male elbows and DN150 oil pipelines, pipes and other components, the connection can be quickly completed to achieve reverse transmission of liquid cargo;

[0008] 3. The pull-off valve assembly is designed with a self-sealing function, which can close the liquid cargo pipelines on both sides after the pull-off valve breaks when the pipeline system is stressed, avoiding injuries to operators after liquid cargo splashes, and ensuring the safe use of the device.

[0009] To achieve the above-mentioned purpose, the technical solution of the present invention is: a liquid cargo reverse transmission supply receiving device, including an oil straight pipe, a hanger pulley assembly, a clamp assembly, a connecting pipe, a pull-off valve assembly, an oil hose, a base, and a liquid cargo pipeline interface. The oil straight pipe is connected to the hanger pulley assembly, and the oil straight pipe is connected to the connecting pipe through the clamp assembly; during supply, the sling rope launched by the supply ship is connected to the base on the civilian oil tanker, the connecting pipe is connected to the oil hose through the pull-off valve assembly, and the oil hose is then connected to the liquid cargo pipeline interface.

[0010] Furthermore, the oil delivery straight pipe and hanger pulley assembly borrow components from the original single-probe refueling device on the supply ship.

[0011] Further, one end of the pull-off valve assembly is a male end, and the other end is a female end.

[0012] Furthermore, the male end of the pull-off valve assembly adopts a CRJ150 male end interface, and the female end adopts a CRJ150 female end interface.

[0013] Furthermore, the sling rope of the hanger block assembly is connected to the base through a wire rope assembly, a pelican hook and a shackle.

[0014] A liquid cargo reverse transmission replenishment receiving method adopts a liquid cargo reverse transmission replenishment receiving device. During replenishment, a supply ship launches a cable through a cable gun, and an operator of a civilian oil tanker or other supply ship receives the cable, connects a wire rope assembly with a pelican hook, a shackle, and a base by manpower or winch traction, and then notifies the supply ship to establish wire rope tension, and then releases a modified refueling head; after the pull-off valve assembly and the oil transfer hose of the civilian oil tanker or other supply ship are connected and checked for air tightness, liquid cargo reverse transmission is performed; after replenishment is completed, the pull-off valve assembly is released to separate it from the refueling head, and then the supply ship retracts the refueling head; after the supply ship releases the wire rope tension, the operator of the civilian oil tanker or other supply ship releases the wire rope assembly from the pelican hook, and the supply ship reclaims the wire rope assembly, and thus a liquid cargo reverse transmission replenishment receiving operation is completed.

[0015] The beneficial effects of the present invention are:

[0016] 1. With the help of existing equipment on supply ships, a quick connection method is adopted to achieve reliable connection with civilian oil tankers or other supply ships.

[0017] 2. Optimize the structure and adopt an easy-to-operate design to facilitate reverse transmission, replenishment and reception of liquid cargo by civilian oil tankers or other supply ships.

[0018] 3. The pull-off valve assembly with self-sealing function is designed to close the liquid cargo pipelines on both sides after the pull-off valve breaks when the pipeline system is stressed, avoiding injury to operators after liquid cargo splashes. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 It is a schematic diagram of the liquid cargo reverse transmission replenishment receiving device and its working status of the present invention. DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1 As shown, a liquid cargo reverse transmission replenishment receiving device provided by an embodiment of the present invention includes an oil delivery straight pipe 1, a hanger pulley assembly 2, a clamp assembly 3, a connecting pipe 4, a CRJ150 male end of a pull-off valve assembly 5, a CRJ150 female end of the other end, a DN150 oil delivery hose 6, a wire rope assembly 7, a pelican hook 8, a shackle 9, a base 10, a liquid cargo pipeline interface 11, etc.

[0022] The oil delivery straight pipe 1 and the hanger pulley assembly 2 are connected to the connecting pipe 4 through the clamp assembly 3 by using the components of the original single-probe refueling device on the supply ship.

[0023] The supply ship fires the cable through the cable gun, and the operator of the civilian oil tanker or other supply ship receives the cable, and connects the wire rope assembly 7 with the pelican hook 8, shackle 9, and base 10 by manpower or winch traction, and then notifies the supply ship to establish the wire rope tension, and then the supply ship releases the modified refueling head.

[0024] After the CRJ150 male end of the pull-off valve assembly 5 of the civil oil tanker or other supply ship is connected to the CRJ150 female end of the other end and the DN150 oil hose 6, the air line is swept by the supply ship to check the air tightness of the pipeline. After the air tightness check is passed, the liquid cargo is reversely transferred. After the replenishment is completed, the line is swept again. Then the pull-off valve assembly 5 is released to separate it from the refueling head, and then the supply ship retracts the refueling head.

[0025] After the supply ship releases the tension of the wire rope, the operator of the civilian oil tanker or other supply ship disengages the wire rope assembly 7 from the pelican hook 8, and the supply ship recovers the wire rope assembly 7, thereby completing a liquid cargo reverse transmission supply and receiving operation.
