Conventional cylindrical underwater products are generally composed of different functional segments. During the assembly, commissioning, and subsequent testing of the products, a large number of disassembly, assembly, and docking operations are required. Small cylindrical underwater products can be disassembled and docked between segments by manual lifting; however, for medium and large cylindrical underwater products, manual lifting is difficult, and lifting equipment is used to assist in disassembly, assembly, and docking. Since the position and angle of the functional segments cannot be precisely fine-tuned during the lifting process, there is a problem of difficulty in achieving accurate docking between the functional segments, and there is a problem that improper operation can easily damage the shell port of the functional segment.

DETAILED DESCRIPTION

[0019] The specific embodiments of the present application are further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application, but are not intended to limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application and not all embodiments. All other embodiments obtained by those of ordinary skill in the art without making creative work are within the scope of protection of this application.

[0020] In the description of the present invention, it should be understood that the terms "center", "transverse", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0022] In the present invention, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0023] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0024] In the present invention, the terms "one embodiment", "some embodiments", "examples", "specific examples", or "some examples" mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples without contradiction.

[0025] In the present invention, the concept of "roughly" describes the main features of an overall structure or shape. When describing the shape of an object, it means that the object mainly presents a certain specific shape, but may differ in non-functional details. These detailed differences do not affect the overall characteristics and can therefore be classified as "roughly" a certain shape. For example, when describing a rectangular object, the expression "roughly rectangular" means that the overall shape of the object is rectangular, but there are differences in certain non-functional details. Similarly, when describing a cube, the expression "roughly cubic" means that the overall shape of the object is a cube, but there are differences in certain non-functional details.

[0026] In the existing technology, it is difficult to achieve the disassembly, assembly and docking operations between the functional segments of medium and large cylindrical underwater products through manual lifting. If lifting equipment is used to assist in the disassembly, assembly and docking, the position and angle of the functional segments cannot be accurately fine-tuned during the lifting process. This makes it difficult to achieve accurate docking between the functional segments and it is easy to damage the shell ports of the functional segments.

[0027] In response to the above problems, the present application makes improvements and innovations and proposes the following embodiments.

[0028] In one embodiment, see Figure 1-Figure 7The present application provides a cylindrical underwater product support device that can be adjusted with multiple degrees of freedom, including a splicable base 100 and a plurality of support adjustment bases 200 that can be installed on the splicable base 100 and can be laterally translated. The support adjustment base 200 includes a support mechanism 1, a rotation mechanism 2, a longitudinal translation mechanism 3, and a lifting mechanism 4; wherein the support mechanism 1 is used to horizontally place a functional section 300 of the cylindrical underwater product, and the functional section 300 can rotate on the support mechanism 1 with its own central axis as the rotation axis, and the rotation mechanism 2 includes a rotation support bearing 2 1, the supporting mechanism 1 is fixedly mounted on the rotary support bearing 21 and can be horizontally rotated, the longitudinal translation mechanism 3 includes a translation screw 31 and a translation nut 32 mounted on the translation screw 31 and can be longitudinally and horizontally moved, the rotary mechanism 2 is fixedly mounted on the translation nut 32 and can be longitudinally translated, the lifting mechanism 4 includes a fixed frame 41 and a lifting frame 42, the fixed frame 41 is mounted on the splicable base 100 and can be horizontally translated, the lifting frame 42 is mounted on the fixed frame 41 and can be vertically lifted, and the longitudinal translation mechanism 3 is fixedly mounted on the lifting frame 42 and can be lifted.

[0029] In this way, a functional section 300 of a cylindrical underwater product is supported by the support mechanism 1 supporting the adjustment seat 200. Therefore, by making the functional section 300 rotate on the support mechanism 1 with its own central axis as the rotation axis, the rotation adjustment of the functional section 300 along its own axis can be realized. The horizontal rotation of the functional section 300 can be realized by driving the support mechanism 1 to rotate horizontally by the slewing mechanism 2. The horizontal movement adjustment of the functional section 300 in the cross section of the underwater product can be realized by driving the slewing mechanism 2 to translate longitudinally by the longitudinal translation mechanism 3. The vertical movement adjustment of the functional section 300 in the height direction of the underwater product can be realized by driving the longitudinal translation mechanism 3 to move vertically by the lifting mechanism 4. The position of the functional section 300 in the underwater product can be adjusted by lateral translation of the lifting mechanism 4 on the splicable base 100. The product can be moved and adjusted in the length direction, thereby providing stable support for each functional section 300 of the cylindrical underwater product, and can perform precise adjustment of the installation position and direction of each functional section 300 in five degrees of freedom, so as to meet the precise fine-tuning of the position and angle of the underwater product during assembly, debugging and testing. The support has high stability and strong load-bearing capacity, and does not require manual lifting. It can effectively prevent the functional section 300 from falling and damaging the shell and internal functional components of the functional section 300. The adjustment accuracy is high, which can effectively improve the docking and assembly quality of the cylindrical underwater product and effectively prevent the shell port of the functional section 300 from being damaged. The adjustment operation is simple and the adjustment efficiency is high, which can effectively improve the efficiency of disassembly, docking and debugging of the cylindrical underwater product.

[0030] Specifically, during the docking and assembly process, each functional segment 300 can be precisely moved and adjusted in the length direction, height direction, and cross-sectional direction of the product through the splicable base 100, the lifting mechanism 4, and the longitudinal translation mechanism 3 respectively. Each functional segment 300 can be rotated and adjusted along its own axis through the support mechanism 1, so as to accurately fine-tune the position and angle of each functional segment 300 to achieve accurate docking between each functional segment 300. Among them, if the functional components inside a functional segment 300 need to be disassembled or debugged separately, the functional segment 300 can be driven to rotate horizontally through the rotating mechanism 2, and the functional segment 300 can be rotated to a direction perpendicular to the product axis to facilitate disassembly and debugging operations.

[0031] In some embodiments, see Figure 1 、 Figure 2 The modular base 100 includes a bottom frame 5, transverse guide rails 6, and transverse sliders 7. The transverse guide rails 6 are fixedly mounted on both sides of the top of the bottom frame 5 along its extension direction. The transverse sliders 7 are mounted on the transverse guide rails 6 for horizontal sliding movement. The fixing bracket 41 is fixedly mounted on the transverse sliders 7. In this way, the lifting mechanism 4 is pushed, and the transverse sliders 7 are used to cause the lifting mechanism 4 to translate laterally on the transverse guide rails 6 of the modular base 100. This adjusts the position of the support adjustment seat 200 on the modular base 100, thereby achieving the movement and adjustment of the functional section 300 along the length of the underwater product.

[0032] In some embodiments, see Figure 1 、 Figure 2 The left and right ends of the bottom frame 5 are respectively fixedly installed with matching first connecting blocks 51 and second connecting blocks 52. The left end face of the first connecting block 51 is flush with the left end face of the bottom frame 5, and the right end face of the second connecting block 52 is arranged beyond the right end face of the bottom frame 5. The inner side of the part of the second connecting block 52 exceeding the bottom frame 5 is provided with a groove that can just accommodate the first connecting block 51. When the first connecting block 51 and the second connecting block 52 on the two bottom frames 5 are connected by bolts, the bottom frame 5 and the transverse guide rail 6 on the splicable base 100 are spliced ​​end to end respectively. In this way, the splicable base 100 can be spliced ​​according to the overall length of the cylindrical underwater product, and the number of support adjustment seats 200 installed on the splicable base 100 can be adaptively configured according to the number of functional sections 300 to meet installation requirements.

[0033] In this embodiment, two height-adjustable threaded feet 53 are fixedly installed on the front and rear outer side walls of the bottom frame 5, respectively. In this way, when splicing the splicable bases 100, the two splicable bases 100 are first adjusted to be aligned at the same height, and then the first connecting block 51 and the second connecting block 52 between the two splicable bases 100 are connected and fixed, so that the two splicable bases 100 are in the same straight line direction, so as to facilitate smooth adjustment of the position of the support adjustment seat 200 on the splicable base 100.

[0034] In some embodiments, see Figure 3-Figure 7 The support mechanism 1 includes a support plate 11, a slide aluminum bar 12, and a rubber roller 13. The support plate 11 can be horizontally rotatably fixed on the slewing support bearing 21. The slide aluminum bar 12 is horizontally fixed at both ends of the top of the support plate 11. Rubber rollers 13 are installed between the two ends of the two slide aluminum bars 12 with adjustable screw spacing. The outer walls of the four rubber rollers 13 abut against the outer wall of the functional section 300 supporting the cylindrical underwater product. The functional section 300 can rotate on the rubber roller 13 with its own central axis as the rotating axis.

[0035] In this way, in the supporting mechanism 1, on the one hand, by using the outer side walls of the four rotatable rubber rollers 13 to abut against the outer side walls of the functional section 300 supporting the cylindrical underwater product, a stable support for a functional section 300 of the cylindrical underwater product can be achieved, and at the same time, the functional section 300 can be rotated around its own central axis as the axis under the action of the four rubber rollers 13, thereby achieving the rotation adjustment of the functional section 300 along its own axis; on the other hand, the rubber rollers 13 are installed on the slide groove aluminum bar 12 by using screws, and the spacing between the rubber rollers 13 at both ends of the slide groove aluminum bar 12 is adjustable, so that the spacing between the rubber rollers 13 at both ends of the slide groove aluminum bar 12 can be adaptively adjusted according to the caliber of the cylindrical underwater product, thereby meeting the support requirements for cylindrical underwater products of different calibers.

[0036] In this embodiment, two straps 14 are provided above the support plate 11 for fastening the functional segment 300 to the rubber rollers 13. Two strap holders 15 and two strap retractors 16 are fixedly mounted on the two ends of the straps 14, corresponding to the ends of the top of the support plate 11, located between the two aluminum runner bars 12. One end of the strap 14 is fixed to the strap holder 15, while the other end of the strap 14 can be tightened and threaded through the strap retractors 16. In this way, the straps 14 and retractors 16 can be used to fasten the functional segment 300 to the four rubber rollers 13 of the support mechanism 1, further preventing the functional segment 300 from falling during docking assembly and horizontal rotation.

[0037] In some embodiments, see Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 The slewing mechanism 2 further includes a translation plate 22. The support plate 11 is fixedly mounted on the rotating ring of the slewing support bearing 21. The fixed ring of the slewing support bearing 21 is fixedly mounted on the translation plate 22. The translation plate 22 is fixedly mounted on the longitudinal translation mechanism 3 so as to be longitudinally translatable. In this manner, the slewing support bearing 21 enables the support plate 11 of the support mechanism 1 to rotate horizontally relative to the translation plate 22 of the slewing mechanism 2. The slewing mechanism 2 then drives the support mechanism 1 to rotate horizontally, thereby achieving horizontal rotation of the functional section 300.

[0038] In some embodiments, see Figure 1 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 The longitudinal translation mechanism 3 also includes a longitudinal slide rail 33, a longitudinal slider 34, and a connecting plate 35. The longitudinal slide rail 33 is horizontally and longitudinally fixedly mounted on the front and rear ends of the top of the upper lifting plate 421 of the lifting frame 42 of the lifting mechanism 4. At least two longitudinal sliders 34 are slidably provided on the two longitudinal slide rails 33. A connecting plate 35 is fixedly mounted on the top of the longitudinal slider 34 on the same longitudinal slide rail 33. The translation screw 31 is rotatably mounted horizontally and longitudinally on the top of the upper lifting plate 421 of the lifting frame 42 through the first bracket 36. Translation handwheels 37 are installed on both end heads of the translation screw 31. The translation nut 32 is installed on the translation screw 31. The translation plate 22 is detachably fixed on the translation nut 32 and the top of the connecting plate 35.

[0039] In this way, the translation screw 31 can be driven to rotate by the translation handwheel 37. Under the limiting action of the longitudinal slide rail 33 on the connecting plate 35 through the longitudinal slider 34, the translation nut 32 slides longitudinally and horizontally on the translation screw 31 as the translation screw 31 rotates, so that the translation nut 32 drives the translation plate 22 to move longitudinally and horizontally on the longitudinal slide rail 33 through the longitudinal slider 34, and then drives the rotary mechanism 2 to move longitudinally through the longitudinal translation mechanism 3 to realize the lateral movement adjustment of the functional section 300 in the cross section of the underwater product.

[0040] In this embodiment, limit blocks 38 are respectively provided at the two end positions of the two longitudinal slide rails 33 corresponding to the longitudinal sliders 34. The limit blocks 38 are fixedly mounted on the upper lifting plate 421 of the lifting frame 42. In this way, the longitudinal sliders 34 can be limited at the two ends of the longitudinal slide rails 33 by the limit blocks 38, thereby preventing the longitudinal sliders 34 from detaching from the longitudinal slide rails 33 and causing the functional section 300 to fall.

[0041] In some embodiments, see Figure 3-Figure 7The fixed frame 41 includes an upper fixed plate 411, a lower fixed plate 412, and a fixed guide column 413. The lifting frame 42 includes an upper lifting plate 421, a lower lifting plate 422, and a lifting guide column 423. The upper lifting plate 421, the upper fixed plate 411, the lower lifting plate 422, and the lower fixed plate 412 are arranged horizontally in sequence from top to bottom. The upper fixed plate 411 and the lower fixed plate 412 are supported and connected by the fixed guide column 413, and the fixed guide column 413 can slide vertically through the lower lifting plate 422 is set, the upper lifting plate 421 and the lower lifting plate 422 are supported and connected by a lifting guide column 423, and the lifting guide column 423 can slide vertically through the upper fixed plate 411; the lifting mechanism 4 also includes a lifting screw 43 and a lifting nut 44, the lifting screw 43 is rotatably installed vertically between the upper fixed plate 411 and the lower fixed plate 412, the lifting nut 44 is installed on the lifting screw 43, and the middle part of the lower lifting plate 422 is fixedly installed on the lifting nut 44.

[0042] Among them, the lifting mechanism 4 also includes a lifting handwheel 45 and a reducer 46. The lifting handwheel 45 is rotatably fixed horizontally on the upper fixed plate 411 through a second bracket 47. The reducer 46 is fixed on the upper fixed plate 411. The lifting handwheel 45 is drive-connected to the input end of the reducer 46, and the output end of the reducer 46 is transmission-connected to the upper end of the lifting screw 43.

[0043] In this way, the lifting handwheel 45 can be used to drive the lifting screw 43 to rotate through the reducer 46. Under the limiting and guiding action of the fixed guide column 413 on the lower lifting plate 422, the lifting nut 44 is vertically lifted and lowered on the lifting screw 43 as the lifting screw 43 rotates, so that the lifting nut 44 drives the lower lifting plate 422 to move vertically, and the lower lifting plate 422 drives the upper lifting plate 421 to move up and down through the lifting guide column 423, that is: the lifting frame 42 drives the fixed frame 41 to move up and down, and then the lifting mechanism 4 drives the longitudinal translation mechanism 3 to move vertically to achieve the lifting and lowering adjustment of the functional section 300 in the height direction of the underwater product.

[0044] In some embodiments, see Figure 3 、 Figure 4 、 Figure 6 、 Figure 7The front and rear ends of the lower fixing plate 412 of the fixing frame 41 are fixedly mounted with locking mechanisms 48. The fixed ends of the locking mechanisms 48 are fixedly mounted on the lower fixing plate 412. The bottom of the transverse guide rail 6 protrudes from the outer side surface of the bottom frame 5. The movable ends of the locking mechanisms 48 are detachably fastened to the bottom of the transverse guide rail 6. In this way, after the lifting mechanism 4 of the support and adjustment seat 200 is laterally adjusted to the desired position on the spliceable base 100, the position of the individual support and adjustment seat 200 on the spliceable base 100 can be locked by operating the locking mechanisms 48 so that the movable ends of the locking mechanisms 48 are firmly fastened to the bottom of the transverse guide rail 6. After the functional sections 300 of the cylindrical underwater product are docked and assembled, each support and adjustment seat 200 can be locked to allow subsequent debugging and experimental operations of the cylindrical underwater product.

[0045] Finally, it should be noted that although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention, and all should be included in the scope of protection of this application.
