Technical Field

[0001] This utility model relates to the field of marine technology, specifically to a leak-proof device for LNG refueling on ships. Background Technology

[0002] Anti-drip devices during LNG bunkering on ships are crucial for ensuring operational safety and reducing environmental pollution. These devices minimize leakage risks while meeting increasingly stringent environmental and safety requirements. Utility model patent CN217109127U discloses an anti-drip device for LNG bunkering on ships, comprising an LNG receiving tank with a cylindrical receiving pool containing a semi-circular cavity. A partition is located below the receiving pool, with hot air holes along its edges. A heating wire is positioned below the partition, followed by exhaust blades. A rotating motor is located below the exhaust blades. A protective curtain is positioned above the LNG receiving tank, with pipe clamps on both sides. This device is simple in structure, highly practical, and easy to use. In the event of LNG dripping during bunkering, it protects the ship's hull from ultra-low temperature corrosion and safeguards personnel from the low temperatures and white vapors produced by LNG vaporization. However, the aforementioned patent has the following shortcomings: when the exhaust blades need to be used, air cannot easily enter from the bottom of the device, making it inconvenient to use the exhaust blades. Therefore, improvements are needed. Utility Model Content

[0022] Please see Figure 3 , Figure 4 , Figure 5 The filter mechanism 5 includes a connecting sleeve 51. The connecting sleeve 51 is fixedly connected inside the anti-drip device body 1. A filter screen 52 is fixedly connected inside the connecting sleeve 51. An installation strip 53 is fixedly connected inside the anti-drip device body 1. A motor 54 is fixedly connected to the lower end of the installation strip 53. The rotating shaft of the motor 54 is rotatably connected to the installation strip 53. A rotating block 55 is fixedly connected to the upper end of the rotating shaft of the motor 54. The rotating block 55 is rotatably connected to the installation strip 53. A brush 56 is fixedly connected to the upper end of the rotating block 55. A rotating sleeve 57 is fixedly connected to the outer side of the brush 56. A support sleeve 58 is fixedly connected to the lower end of the connecting sleeve 51. The support sleeve 58 contacts the anti-drip device body 1. The rotating sleeve 57 is rotatably connected inside the support sleeve 58. An annular ring is in contact inside the support sleeve 58. The annular sleeve 59 contacts the rotating sleeve 57. The inside of the annular sleeve 59 contacts the guide block 510, and the outside of the guide block 510 is provided with a spring 511. One end of the spring 511 is fixedly connected to the annular sleeve 59, and the other end of the spring 511 is fixedly connected to the support sleeve 58. By designing the spring 511, the annular sleeve 59 has an elastic force. The support sleeve 58 is fixedly connected to the guide block 510. The annular sleeve 59 contacts the brush 56, and the brush 56 contacts the filter screen 52. The filter screen 52 can filter external dust, thereby preventing dust from entering the device and making the device easy to use. Rotating the brush 56 and other components causes the brush 56 to rotate and scrape the filter screen 52, thereby preventing the filter screen 52 from becoming clogged and preventing the working efficiency of the filter screen 52 from decreasing.

[0023] Please see Figure 1 , Figure 2 , Figure 3The adjusting mechanism 7 includes a threaded rod 71. The support leg 6 is internally connected to the threaded rod 71 via a threaded connection. A handle 72 is fixedly connected to the upper end of the threaded rod 71. A support block 73 is rotatably connected to the outer side of the threaded rod 71. A fixing sleeve 74 is rotatably connected to the inside of the support block 73. The fixing sleeve 74 is fixedly connected to the threaded rod 71. An annular groove 75 is formed inside the fixing sleeve 74. A screw 76 is slidably connected inside the annular groove 75. By designing the screw 76, the support block 73 and the fixing sleeve 74 can be connected. The support block 73 is internally connected to the screw 76 via a threaded connection. A guide groove 77 is formed inside the support leg 6. The guide rod 78 is slidably connected inside the groove 77. The guide rod 78 is fixedly connected to the support block 73. By designing the guide rod 78, the support block 73 can be guided. The lower end of the support block 73 is fixedly connected to the limiting pad 79. By rotating the threaded rod 71, the support leg 6 will move in a threaded motion. The threaded rod 71 rotates downward, causing the support block 73 and the limiting pad 79 to move downward. When the limiting pad 79 moves downward and contacts the ground, the entire device can move upward. After the limiting pad 79 moves downward to the designated position, the height of the device can be adjusted, which makes it difficult for air to enter from the bottom of the device, so that the exhaust blades 4 on the device can be used.

[0024] The specific implementation process of this utility model is as follows: The basic structure and basic principle of the anti-drip device for ship LNG refueling have been disclosed in the utility model patent with publication number CN217109127U, and will not be repeated here;

[0025] When the device reaches the designated position, turn the handle 72. The rotation of the handle 72 drives the threaded rod 71 to rotate. The rotation of the threaded rod 71 causes threaded movement with the support leg 6, which in turn causes the threaded rod 71 to have relative displacement. The rotation of the threaded rod 71 drives the fixed sleeve 74 and support block 73 to move downward. The downward movement of the support block 73 drives the guide rod 78 and the limiting pad 79 to move downward. When the limiting pad 79 moves downward and contacts the ground, the entire device can move upward. After the limiting pad 79 moves downward to the designated position, the height of the device can be adjusted, which makes it difficult for air to enter from the bottom of the device, allowing the exhaust blades 4 on the device to be used.

[0026] When the device is in use, the filter screen 52 can filter external dust, thereby preventing dust from entering the device and making the device easy to use. When the filter screen 52 is used for a long time, the motor 54 is started. The motor 54 drives the rotating block 55 to rotate. The rotating block 55 rotates and drives the brush 56 to rotate. The brush 56 rotates and drives the rotating sleeve 57 to rotate. The brush 56 rotates and scrapes the filter screen 52, thereby preventing the filter screen 52 from becoming clogged and preventing the working efficiency of the filter screen 52 from decreasing.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
