DETAILED DESCRIPTION

[0047] The utility model will be further described below in combination with the drawings and specific embodiments. Figures 1-15

[0048] The embodiment provides a kind of unmanned super-speed warship power system installation rack, which includes support framework 2, fixed support 1, damping support 3.The fixed support 1 is hollow frame structure, and its inside contains power system 4 (including various aeroengines);The front end surface of fixed support 1 is connected with damping support 3, and support framework 2 is supported below fixed support 1 and damping support 3, and plays the role of supporting stability.The damping support 3 is the frame structure of cone frustum, and fixed support 1 is cylindrical structure (can be adjusted according to aeroengine appearance, for example, form cone structure), and the rear end surface of damping support 3 is coaxially connected with the front end surface of fixed support 1 (i.e. damping support 3 is installed at the forefront of overall structure).

[0049] ​The front end of the power system 4 is close to the damping support 3, and the damping support 3 is used to reduce the impact force at the starting moment and the acceleration moment of the power system 4, so that the impact force received by the mounting rack can be effectively reduced, the impact damage of the mounting rack to the warship is further reduced, and the service life of the mounting rack and the warship is further prolonged.

[0050] As an example, the support angle of the fixed support 1 on the support framework 2 (that is, the angle between the axis of the fixed support 1 and the horizontal direction) needs to be determined according to the internal structure and space of the unmanned warship.

[0051] The mounting rack as a whole is welded after being cut and bent from standard rectangular pipes 1-4, so that the bearing capacity of the mounting rack can be ensured, and the support framework 2, the fixed support 1 and the damping support 3 are connected and fastened by high-strength bolts, so that the overall structural strength is ensured.

[0052] The damping support 3 is the main damping structure in the mounting rack, and the damping support 3 includes a plurality of coaxial and axially spaced annular structures 3-1, the diameters of the annular structures 3-1 gradually decrease from back to front (the sizes of the annular structures 3-1 gradually decrease step by step); the adjacent two layers of annular structures 3-1 are connected by a plurality of circumferentially uniformly spaced damping shock absorbers 3-2, thereby forming a frustoconical frame structure; specifically, the annular structure 3-1 is provided with a damper mounting hinge hole 10, and the two ends of the damping shock absorber 3-2 are respectively connected to the corresponding damper mounting hinge hole 10. The damping shock absorber 3-2 is an important damping component in the damping support 3, which is used to ensure the stable state between the power system 4 and the unmanned warship.

[0053] As an example, the mounting rack adopts a two-stage damping structure (that is, the damping support 3 includes three coaxial and spaced annular structures 3-1, thereby spacing and clamping two layers of damping shock absorbers 3-2), the first annular structure has the largest diameter size, which is consistent with the size of the front end face of the fixed support 1, and a plurality of mounting fixing holes are processed on the first annular structure in the circumferential direction, which are used to connect the damping support 3 and the support framework 2 firmly. The diameter of the second annular structure is smaller than that of the first annular structure. For the third annular structure, high-strength bolt connection is adopted between the third annular structure and the support framework 2, and the bolt mounting hole needs to be made on site during actual installation.

[0054] The damping support 3 is used to disperse the forward or backward impact force generated by the engine at the starting, accelerating and decelerating moments of the power system 4 to the support framework 2 and the warship body, so that the service life of the engine mounting rack and the warship is prolonged to a certain extent.

[0055] The installation rack is designed in a modular manner. For example, the fixed support 1 comprises a fixed support upper module 1-1 and a fixed support lower module 1-2. Both the fixed support upper module 1-1 and the fixed support lower module 1-2 are frame structures with a semicircular cross section (the semicircular frame structure comprises a plurality of sector structures 1-3 arranged at intervals along the axial direction and a plurality of rectangular tubes 1-4 used for connecting the sector structures 1-3, which are welded to ensure the structural strength of the fixed support 1). The fixed support upper module 1-1 and the fixed support lower module 1-2 are oppositely open to form a complete cylindrical frame structure. The fixed support upper module 1-1 and the fixed support lower module 1-2 are connected by fasteners (including high-strength bolts) to facilitate the installation of the power system 4.

[0056] The modular design can quickly complete the overall assembly of the installation rack, improve production efficiency, and facilitate the assembly and maintenance of the modules. The modular design advantage also includes that, under the premise of ensuring the load bearing capacity and structural strength of the installation rack, the overall structure of the installation rack and the weight distribution of the parts of each module are reasonably designed through design verification and optimization design, the balance between strength and lightness is achieved, and the reliability of the overall structure connection is ensured.

[0057] The fixed mounting structure 5 is arranged on the rear end surface of the fixed support 1 to ensure the size matching, structure fitting, and fastening connection with the power system 4. The fixed mounting structure 5 is formed by the butt joint of two semicircular ring structures, which are fitted with the rear end frame of the upper and lower modules of the fixed support 1 and welded with the fixed support 1 to increase the firmness of the fixed support 1.

[0058] Because the rear end of the existing power system 4 is a cone, the contact with the installation rack is a line contact, and the local pressure is relatively large. The fixed mounting structure 5 is processed with a conical surface that fits the conical surface of the rear end of the power system 4, which can ensure the firmness and reliability of the installation of the installation rack and the power system 4. In addition, the fixed mounting structure 5 is completely matched with the conical structure of the tail of the power system 4 in size, and the rear end of the engine is firmly fixed on the fixed support 1 by welding.

[0059] The front end of the fixed support 1 is completely matched with the front end of the engine. The front end of the fixed support 1 is processed with mounting threaded holes, and the front end of the power system 4 is fastened and connected by high-strength bolts (the front end of the power system 4 itself has a certain structure, and the installation rack can be installed through the structure of the power system 4).

[0060] Between the front end and the rear end of the fixed support 1, a plurality of hinged supports 7 are arranged on the inner side in the circumferential direction, and a hinged hole 8 is arranged on each hinged support 7; a plurality of hinged points 9 are welded on the outer side wall of the power system 4 (on the premise of not affecting the function of each system reserved in the engine itself), the hinged points 9 correspond to the hinged holes 8 one by one, and the connection strength between the power system 4 and the fixed support is ensured.

[0061] The support framework 2 is the main support component of the mounting rack, a plurality of sets of connecting plates 6 are mounted on the upper end of the support framework 2 and the part where the lower module 1-2 of the fixed support contacts, the fixed support 1 and the support framework 2 are connected into a whole through fasteners (including high-strength connecting bolts) between each corresponding connecting plate 6, so that the stability of the whole mounting rack is improved. The support framework 2 is also one of the important components for connecting the power system 4 and the ship into a whole. The specific connection structure and fixing mode between the support framework 2 and the ship is determined according to the actual structure of the ship, so that the overall connection strength of the two is ensured.

[0062] In summary, the above is an embodiment of the present application, and is not used to limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
