[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0019] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.
[0020] like Figure 1-Figure 4 As shown, a mobile LNG receiving station storage and refueling platform includes a hull 1, which can be a ferry, ocean supply vessel, or coastal patrol vessel. Hull 1 is circumferentially provided with an anti-collision unit 2, which is disposed on the hull 1 via a mounting plate 3. The mounting plate 3 can be configured to fit the circumferential wall of hull 1 and can be fixedly connected to the circumferential wall of hull 1 at corresponding positions via bolts or other means. The anti-collision unit 2 is disposed on the mounting plate 3 and includes a front airbag 4 and a rear airbag 5, which are connected via a communication unit. The rear airbag 5 is disposed on the mounting plate 3, with the front airbag 4 located at the front end. The communication unit includes a first communication channel and a second communication channel. The first communication channel is configured to allow airflow from the front airbag 4 to enter the rear airbag 5 through the first communication channel, and the second communication channel is configured to allow airflow from the rear airbag 5 to enter the front airbag 4 through the second communication channel.
[0021] The front end of the front airbag 4 is provided with an anti-collision head 14, and the interior of the anti-collision head 14 is filled with elastic material. When the front end is hit, the anti-collision head 14 squeezes the front airbag 4 toward the rear end, and the airflow in the front airbag 4 enters the rear airbag 5 through the connecting channel 1, and part of the airflow in the rear airbag 5 flows back to the front airbag 4 through the connecting channel 2, thereby resisting the impact force borne by the front end and slowing down the deformation of the front and rear airbags 5.
[0022] In some preferred embodiments, a coaxial inner positioning ring 6 and outer positioning ring 7 are disposed between the front airbag body 4 and the rear airbag body 5. The outer positioning ring 7 and the inner positioning ring 6 have corresponding supporting forces, and a predetermined gap is provided between the outer ring wall of the inner positioning ring 6 and the inner ring wall of the outer positioning ring 7. The inner positioning ring 6 and the outer positioning ring 7 can be made of rubber, such as a tire of appropriate size (with corresponding axial and radial deformation forces and supporting forces). They are positioned between the front airbag body 4 and the rear airbag body 5 to relieve the impact and compressive deformation received, and to increase the stability of the connection between the front airbag body 4 and the rear airbag body 5.
[0023] It should be noted that an airbag main pipe 8 is arranged between the front airbag body 4 and the rear airbag body 5. The airbag main pipe 8 is located in the positioning inner ring 6. The outer wall of the airbag main pipe 8 abuts against the inner ring wall of the positioning inner ring 6. The airbag main pipe 8 has an inner diameter of a predetermined size and forms a connecting channel one; an airbag branch pipe 9 is arranged between the front airbag body 4 and the rear airbag body 5. The airbag branch pipe 9 is provided with multiple groups. The airbag branch pipe 9 is located between the positioning outer ring 7 and the positioning inner ring 6, and the outer diameter of the airbag branch pipe 9 is adapted to the predetermined gap. The airbag branch pipe 9 has an inner diameter of a predetermined size and respectively forms a connecting channel two. Corresponding one-way valves are respectively arranged in the airbag main pipe 8 and the airbag branch pipe 9. The airbag main pipe 8 is positioned on the positioning inner ring 6, and the airbag branch pipe 9 is positioned between the positioning inner ring 6 and the positioning outer ring 7. When the airflow flows, the positioning inner ring 6 and the positioning outer ring 7 restrain the airbag main pipe 8 and the airbag branch pipe 9, reducing the circumferential deformation of the airbag main pipe 8 and the airbag branch pipe.
[0024] In some preferred embodiments, a positioning body 10 is configured in the rear airbag body 5, and an extrusion body 11 is configured in the front airbag body 4. The positioning body 10 and the extrusion body 11 respectively have corresponding elastic deformation forces, and the front end of the positioning body 10 and the rear end of the extrusion body 11 are slidably connected in a connecting channel. Specifically, a sliding sleeve 12 is configured at the front end of the positioning body 10, and a sliding body 13 adapted to the sleeve is configured at the rear end of the extrusion body 11. One end of the sliding body 13 is located in the sleeve, and the rear end of the sleeve can be filled with elastic deformation material. When the sliding body 13 is squeezed and continues to extend into the sleeve, it has a certain buffering effect. The rear end of the positioning block is outwardly expanded, and the front end of the extrusion body 11 is outwardly expanded. The extrusion body 11 and the filling body can be equivalent to the "skeleton" of the front airbag body 4 and the rear airbag body 5, assisting the front airbag body 4 and the rear airbag body 5 in buffering and unloading.
[0025] The specific use is as follows: the anti-collision unit 2 is sequentially arranged at appropriate circumferential positions of the hull 1 through the mounting plate 3; after the anti-collision head 14 at the front end of the anti-collision unit 2 is hit, it squeezes the front airbag 4 toward the rear end, and the front airbag 4 squeezes the positioning inner ring 6 and the positioning outer ring 7 toward the rear end, and continues to squeeze the rear airbag 5 toward the rear end. The positioning inner ring 6 and the positioning outer ring 7 are supported between the front airbag 4 and the rear airbag 5, reducing the impact force and reducing the deformation of the device. In addition, when the front airbag 4 is squeezed and deformed, the internal airflow enters the rear airbag 5 through the airbag main pipe 8. Part of the airflow in the rear airbag 5 can flow back to the front airbag 4 through the airbag branch pipe 9, reducing the acceleration of the deformation of the front airbag 4. Combined with the above structure, the overall deformation of the anti-collision unit 2 can be reduced, and the buffering and unloading effect can be improved.

In short, if those skilled in the art are inspired by this, and without departing from the purpose of the invention of the present invention, they can design structural methods and embodiments similar to the technical solution without creativity, and they should all fall within the scope of protection of the present invention. Each component of the present application can be driven by a corresponding external motor, which is a prior art and will not be described in detail in this application.
