Description

Technical Field

[0001] This invention relates to the technical field of maritime replenishment, and more specifically, to a maritime replenishment rotating receiving device. Background Technology

[0002] Ships require substantial supplies of fuel, fresh water, and food during maritime transport operations, with fuel replenishment being particularly crucial, as fuel is to a ship what blood is to a person. To ensure normal operation, consumed fuel, fresh water, and other supplies must be replenished promptly. However, factors such as ship draft, port depth, number of berths, and sea conditions make shore replenishment increasingly difficult, necessitating replenishment while anchored or at sea. Currently, the technology for replenishing fuel and other supplies at sea is primarily used by the military, with supply ships refueling other warships. Some civilian merchant ships can be requisitioned as military vessels for personnel and material transport during wartime. To ensure the supply of fuel, food, and other materials during transport, it is imperative to consider equipping civilian ships with replenishment receiving devices.

[0003] Common methods of replenishment at sea include: lateral berthing replenishment, lateral cableway replenishment, longitudinal replenishment, and vertical replenishment. Among these, berthing replenishment is easily affected by sea conditions, cannot guarantee the safety between vessels, and is not suitable for the trend towards larger and faster ships, and has been gradually phased out. In longitudinal replenishment, the replenishing ship is in front and the receiving ship is behind, with relatively low replenishment capacity between the two ships. Vertical replenishment is a three-dimensional replenishment method that can adapt to various navigation conditions, but it requires the use of a replenishment helicopter, which is costly and has high operational requirements, making its widespread application currently impractical. Lateral cableway replenishment involves erecting a cableway between the two ships to replenish supplies. The use of cargo frames or cableways to further lay oil and water pipelines is a simple and efficient operation with strong replenishment capabilities, making it the main method for current military and future commercial ship development. However, most civilian ships are not equipped with replenishment devices that match the size of military replenishment equipment. The use of such replenishment devices in the civil aviation sector is not common. Newly built civilian ships with complete replenishment devices are less than ideal in terms of cost and functional utilization. Even if the receiving devices on civilian ships are used, their fixed-angle design limits their application scenarios. There is an urgent need for a replenishment device that can solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a transverse cableway resupply device that can rotate freely to increase the resupply application scenarios.

[0005] The technical solution of the present invention is: to provide a marine replenishment rotating receiving device, the device comprising: a fixed base, a movable truncated cone, a large pin, a base, a tie rod, a tensioning screw, a rotating base, a column, and a rotating shaft;

[0006] The bottom of the fixed base is welded and fixed to the hull deck. The movable truncated cone is stacked on the fixed base. A rotating shaft is installed at the center of the bottom of the movable truncated cone. The bottom end of the rotating shaft is connected to the center of the top of the fixed base. The movable truncated cone can rotate around the shaft on the fixed base.

[0007] The upper surface of the movable truncated cone has a ring of circular holes, and the fixed base has a ring of concave holes at the corresponding positions of the circular holes. The large pin is inserted into the overlapping circular holes and concave holes to fix the movable truncated cone.

[0008] At least three bases are regularly distributed and welded to the upper surface of the movable circular platform, one of which is riveted to a column; the remaining bases are each riveted to a tie rod, with a tension screw at the center of the tie rod to adjust its length.

[0009] A rotating base is welded to the top of the column, and the tops of all the tie rods are riveted to the bottom of the rotating base with small pins.

[0010] In any of the above technical solutions, the device further includes: an indicator;

[0011] An indicator is mounted on the edge of the movable frustum, and the edge of the fixed base is marked with graduations. The indicator reads the rotation angle of the movable frustum by the graduations that overlap with its own.

[0012] In any of the above technical solutions, the base and indicator riveted to the column are located on the same diameter of the movable frustum, and the column can move within the vertical plane of the diameter.

[0013] In any of the above technical solutions, the device further includes: a small pin;

[0014] The column is riveted to the base via a small pin, the tie rod is riveted to the base via a small pin, and the tie rod is riveted to the slewing base via a small pin.

[0015] In any of the above technical solutions, the device further includes: a rotary joint;

[0016] The rotary joint is installed on the upper surface of the rotary base and connects to the supply port of the supply ship.

[0017] In any of the above technical solutions, the left and right rotation angles of the rotary joint are further greater than 30 degrees.

[0018] In any of the above technical solutions, a transition shackle is further added to the rotary joint for dry goods replenishment.

[0019] The beneficial effects of this invention are:

[0020] In the technical solution of this invention, the movable truncated cone can rotate on the fixed base, and the length of the pull rod can be adjusted by the tightening screw. The above two points allow the rotating base and the rotating joint to face any direction, greatly reducing the relative position requirements of the two ships when resupplying.

[0021] The slewing angle of the rotary joint is greater than 30 degrees, which meets the requirements for misalignment angle in the existing supply specifications. Attached Figure Description

[0030] The fixed base 1 has a scale marked on its edge, and the indicator 12 is installed on the edge of the movable frustum 2. The rotation angle of the movable frustum 2 can be read by the indicator 12 corresponding to the scale of the fixed base 1. A ring of circular holes is opened on the upper surface of the movable frustum 2, and a ring of concave holes is opened on the fixed base 1 at the position corresponding to the circular holes. The large pin 3 is inserted into the overlapping circular holes and concave holes to fix the movable frustum 2.

[0031] Three bases 4 are welded to the movable truncated cone 2 in a triangular arrangement. One of the bases 4 and the indicator 12 are located on the same diameter of the movable truncated cone 2. The base 4 is riveted to the column 9 by a small pin 10. The column 9 can move within the vertical plane of the diameter. The other two bases 4 are riveted to the pull rod 5 by a small pin 10. The center of the pull rod 5 is a tension screw 6, which can adjust the length of the pull rod 5.

[0032] A rotating base 7 is welded to the top of the column 9, and a rotating joint 8 is installed on the surface of the rotating base 7 for refueling; the top ends of the two tie rods 5 are riveted to the bottom of the rotating base 7.

[0033] Specifically, the swivel joint 8 has a left and right rotation angle greater than 30 degrees, meeting the requirements for misalignment angles in the naval replenishment specifications. The swivel joint 8 is compatible with the installation dimensions of the naval liquid cargo receiving head. For dry cargo replenishment, a transition shackle can be added in front of the swivel joint 8 for use.

[0034] The rotary joint 8 also includes an additional transition shackle for dry cargo replenishment.

[0035] In another embodiment of the present invention, when preparing to receive supplies, the crew rotates the movable truncated cone 2 to a suitable angle according to the angle of visual observation or indicator 12 so that the rotary joint 8 faces the supply ship in the horizontal direction. The large pin 3 is inserted into the round hole of the overlapping movable truncated cone 2 and the concave hole of the fixed base 1 to fix them. Then, the length of the two tie rods 5 is adjusted by tightening screw 6 to adjust the elevation angle of the rotary joint 8. Finally, the rotary joint 8 is connected to the connector of the supply ship to complete the supply.

[0036] In summary, the present invention proposes a rotating receiving device for marine replenishment, comprising: a fixed base, a movable truncated cone, a large pin shaft, a base, a tie rod, a tensioning screw, a rotating base, a column, and a rotating shaft.

[0037] The bottom of the fixed base is welded and fixed to the hull deck. The movable truncated cone is stacked on the fixed base. A rotating shaft is installed at the center of the bottom of the movable truncated cone. The bottom end of the rotating shaft is connected to the center of the top of the fixed base. The movable truncated cone can rotate around the shaft on the fixed base.

[0038] The upper surface of the movable truncated cone has a ring of circular holes, and the fixed base has a ring of concave holes at the corresponding positions. The large pin is inserted into the overlapping circular holes and concave holes to fix the movable truncated cone.

[0039] At least three bases are regularly distributed and welded to the upper surface of the movable circular platform, one of which is riveted to a column; the remaining bases are each riveted to a tie rod, with a tension screw at the center of the tie rod to adjust its length.

[0040] A rotating base is welded to the top of the column, and the tops of all the tie rods are riveted to the bottom of the rotating base with small pins.

[0041] In this invention, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium.
