Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, specifically to a foldable support structure for shipboard equipment. Background Technology

[0002] When using unmanned surface vessels (USVs) for underwater topographic surveying, it is typically necessary to carry a variety of equipment, including aerodynamic systems (such as propellers), positioning equipment (such as GNSS receivers), video equipment (such as cameras and laser scanners), and surveying equipment (such as multibeam echo sounders, side-scan sonar, single-beam echo sounders, and water quality sensors). The coordinated operation of these devices enables USVs to efficiently complete complex underwater surveying tasks.

[0003] However, traditional underwater topographic surveying unmanned surface vessel (USV) platforms have several limitations in practical use. First, traditional USVs mostly employ fixed equipment mounting schemes, meaning the orientation and position of the onboard equipment are typically fixed and cannot be adjusted or replaced, making it impossible to flexibly adjust equipment configuration according to different mission requirements. Second, traditional USVs also present inconveniences during transportation and handling. Due to the fixed installation of onboard equipment, the overall size of the USV is large, occupying a significant amount of space, leading to difficulties in loading, transporting, and handling. Furthermore, different usage scenarios have varying requirements for the height and depth of the onboard equipment. Traditional USVs lack the ability to adjust the height and depth of the equipment, making it difficult to adapt to complex and changing environmental conditions.

[0004] In recent years, some integrated unmanned surface vessels (USVs) for surveying have emerged. While these USVs have improved the integration and functionality of equipment to some extent, their high cost and the fixed, non-replaceable positions of their mounted components still fail to meet users' demands for equipment flexibility and economy. Therefore, there is an urgent need for a new type of connection and support structure that can enable the height adjustment, folding and storage, and rapid replacement of shipborne equipment, thereby improving the flexibility, transportation convenience, and environmental adaptability of USVs.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] Please see Figure 1-7 This utility model provides a technical solution:

[0035] The foldable support structure for shipborne equipment provided by this utility model, such as Figures 1-3As shown, it includes a retractable Z-shaped buckle device 1, which is a vertically retractable Z-shaped buckle formed by connecting a middle U-shaped component 101 and two bottom L-shaped components 102 on both sides. The U-shaped component 101 is inverted and has vertical grooves 103 on both its left and right vertical side walls. The vertical side walls of the L-shaped component 102 have vertical protrusions 104 that match the vertical grooves 103 on the vertical side walls of the U-shaped component 101. The vertical protrusions 104 of the L-shaped component 102 are inserted into the vertical grooves 103 on both sides of the U-shaped component 101 and can slide up and down and be limited and fixed along the vertical protrusions 104. The L-shaped component 102 located on the upper part of the vertical protrusion 104 is also connected to a limiter 105 that matches the vertical side wall of the U-shaped component 101. Screw holes are provided on the limiter 105, the upper end of the L-shaped component 102, and the side wall of the U-shaped component 101, and are connected by fastening bolts. The telescopic Z-shaped buckle device 1 can be fixed and slide telescopically extended by tightening and loosening the fastening bolts.

[0036] The inverted U-shaped component 101, serving as the main load-bearing part, disperses stress and prevents deformation caused by localized concentrated loads. The horizontal sections at the bottom of the L-shaped components 102 on both sides extend laterally to form a wider support surface, increasing the contact area with the hull, preventing slippage, and making the Z-shaped support buckle structure more stable. The vertical grooves 103 on the side walls of the U-shaped component 101 and the vertical protrusions 104 of the L-shaped component 102 cooperate to provide guidance, ensuring smooth vertical sliding and preventing the retractable Z-shaped support buckle from shifting or wobbling during adjustment. The limiter 105 fits tightly with the side walls of the L-shaped component 102 and the U-shaped component 101, limiting the sliding range of the U-shaped component 101 and preventing excessive sliding that could cause the structure to detach. The fastening bolts enhance the connection strength between the L-shaped component 102 and the U-shaped component 101, making the device more stable and reliable when bearing the load of shipboard equipment.

[0037] When the retractable Z-shaped buckle device 1 needs to be adjusted in height, the fastening bolts are loosened, and the vertical groove 103 on the side wall of the U-shaped component 101 slides up and down along the vertical protrusion 104 of the L-shaped component 102 to adjust the height of the device. Once the desired height is reached, the fastening bolts are tightened to fix the device structure. This design allows the shipborne equipment to flexibly adjust its installation height according to actual needs to adapt to different operating scenarios. At the same time, when not in operation, the retraction of the device can reduce the space occupied, facilitating transportation and storage.

[0038] like Figure 4As shown, it also includes a foldable tripod 2 mounted on a retractable U-shaped buckle device 1. The foldable tripod 2 includes an L-shaped connecting bracket formed by hinged one end of a long U-shaped slot frame 202 and a short U-shaped slot frame 201 via a first rotating shaft 203. The bottom of the short U-shaped slot frame 201 and the top platform of the U-shaped component 101 are both provided with screw holes, and the two are detachably connected by bolts. The side wall of the long U-shaped slot frame 202 is provided with a long strip-shaped sliding groove 4 parallel to the long U-shaped slot frame 202, and a connecting bracket 3 is also connected between the long U-shaped slot frame 202 and the short U-shaped slot frame 201. One end of the connecting bracket 3 is hinged in the short U-shaped slot frame 201 via a second rotating shaft 204 that passes laterally through the short U-shaped slot frame 201; the other end is a free end, and its free end is engaged in the sliding groove 4 of the long U-shaped slot frame 202 via a snap-fit ​​part 205, and the snap-fit ​​part 205 can slide within the range of both ends of the sliding groove 4.

[0039] Two limit self-locking switches 5 are also installed on the long U-shaped groove frame 202 located at both ends of the slide 4; when the long U-shaped groove frame 202 and the short U-shaped groove frame 201 are set vertically, the locking part 205 is located at the lower end of the slide 4. At this time, the self-locking switch 5 located at the lower end of the slide 4 limits and locks the locking part 205 located at the lower end of the slide 4, fixing the foldable tripod 2 into an L-shaped structure; such as Figure 5 As shown, when the long U-shaped slot frame 202 and the short U-shaped slot frame 201 are folded up, the long U-shaped slot frame 202 folds down, causing the free end of the connecting bracket 3 to slide upward in the slide groove 4. Finally, the connecting bracket 3 is completely retracted into the slide groove 4 of the long U-shaped slot frame 202. At this time, the self-locking switch 5 located at the upper end of the slide groove 4 limits and locks the snap-fit ​​part 205 located at the upper end of the slide groove 4, and horizontally combines the long U-shaped slot frame 202 and the short U-shaped slot frame 201 into a "I"-shaped structure.

[0040] The short U-shaped trough 201 and the long U-shaped trough 202 slide within the range of both ends of the slide groove 4 of the long U-shaped trough 202 via the free end of the connecting bracket 3, which can achieve 90-degree rotation and folding. At the same time, the self-locking switch 5 can further fix the tripod device 2 into an L-shaped or straight structure, so that the foldable tripod 2 can be fixedly switched between the unfolded state and the folded state, which enhances the stability, flexibility and operability of the device, improves the safety and efficiency of the operation, facilitates the measurement work of shipborne equipment during operation and the storage and transportation when not in operation, and is applicable to a variety of above-water and underwater operation scenarios.

[0041] This utility model discloses a foldable support structure for shipborne equipment. Through a retractable U-shaped fixing buckle device and a foldable triangular frame design, it allows for flexible adjustment of the shipborne equipment in the height, horizontal, and vertical directions. The shipborne equipment can be adjusted to a suitable position according to operational needs, and the operation is completed. backIt can be folded and stored, significantly reducing the overall space occupied by the unmanned vessel and greatly improving the convenience of transportation and storage.

[0042] Specifically, such as Figure 4 As shown, the width between the two side walls of the long U-shaped slot 202 is smaller than the width between the two side walls of the short U-shaped slot 201. The openings of the short U-shaped slot 201 and the long U-shaped slot 202 are arranged opposite each other, and the long U-shaped slot 202 can be stored in the opening of the short U-shaped slot 201. This allows the short U-shaped slot 201 and the long U-shaped slot 202 to better cooperate during folding and unfolding, avoiding structural interference. The overall structure is also more compact, reducing the space occupied by the device in the folded state. On the slot wall of the long U-shaped slot 202, the end that is hinged to the short U-shaped slot 201 is also provided with a rounded transition chamfer. The rounded transition chamfer design reduces the friction of the rotating contact surface at the hinge point between the long U-shaped slot 202 and the short U-shaped slot 201, making the rotation of the long U-shaped slot 202 inside the short U-shaped slot 201 smoother and facilitating the operation of the tripod device 2 during folding and unfolding.

[0043] like Figure 4 As shown, the side wall of the long U-shaped slot frame 202 is also provided with a clearance groove 206 that matches the mounting position of the second rotating shaft 204; the distance from the clearance groove 206 to the first rotating shaft 203 is equal to the distance from the second rotating shaft 204 to the first rotating shaft 203, and the width of the clearance groove 206 is greater than or equal to the width of the mounting position of the second rotating shaft 204. The clearance groove 206 provides sufficient movement space for the snap-fit ​​part 205, ensuring that the connecting bracket 203 is not blocked by the side wall of the long U-shaped slot frame 202 and the snap-fit ​​part 205 when rotating, thereby realizing the smooth folding and unfolding of the device.

[0044] like Figure 3 As shown, the bottom horizontal plate of the L-shaped component 102 of the retractable U-shaped buckle device 1 has screw holes; these are used to fasten the retractable U-shaped buckle device 1 to the unmanned vessel hull using bolts, thereby installing the retractable U-shaped buckle device 1 on the unmanned vessel hull. The position of the pre-drilled screw holes on the unmanned vessel hull can be determined according to the actual situation and measurement needs. The long U-shaped slot 202 of the foldable tripod 2 also has screw holes on its side wall for installing shipboard equipment.

[0045] The working principle of the foldable support structure for shipborne equipment of this utility model is as follows:

[0046] like Figure 6 and Figure 7 As shown, the bottom of the short U-shaped groove frame 201 in the foldable tripod 2 is fastened with bolts. existAbove the U-shaped components 101 on the two retractable Z-shaped buckle devices 1, the shipborne equipment is fixed to the side wall of the long U-shaped trough frame 202 in this support structure by means of mounting, screw fixing, etc., and then the bottom of the L-shaped component 102 in the retractable Z-shaped buckle device 1 is fastened to the hull of the unmanned vessel with bolts. When loading, transporting and moving the unmanned vessel to the operating water area, the retractable Z-shaped buckle device 1 and the foldable tripod 2 are placed in a retracted and folded state for easy handling and loading. When underwater measurements are required, the unmanned vessel sets the foldable tripod 2 vertically into an L-shape before launching, placing it in the working state. The height of the Z-shaped fixing buckle device 1 is flexibly adjusted according to the work site conditions to adjust the position of the onboard equipment to a suitable height and depth for underwater measurement. After the underwater measurement is completed, the foldable tripod 2 is folded into a straight line, and the retractable Z-shaped buckle device 1 is placed in the retracted state, so that the retractable Z-shaped buckle device 1 and the foldable tripod 2 are in the retracted and folded state for handling and loading.

[0047] In summary, the foldable support structure for shipborne equipment of this utility model is simple and ingenious in structure, and has low manufacturing cost. Through the cooperation of the retractable Z-shaped fixing support buckle and the foldable triangular frame device, the shipborne equipment can be adjusted to a suitable position according to the operational requirements, and the operation is completed. back It can be folded and stored, which greatly improves the convenience of transportation and storage. At the same time, it can also carry a variety of replaceable shipboard equipment in different positions on the hull of the unmanned vessel to meet a variety of water and underwater operation needs, effectively improving the functionality and applicability of the unmanned vessel.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
