Description

Technical Field

[0001] This invention belongs to the field of research vessel technology, specifically, it relates to a semi-concealed stern research area structure for a polar research vessel. Background Technology

[0002] The stern of a polar research vessel serves as a core scientific research area, housing various sophisticated scientific equipment. To facilitate personnel climbing to the top of the canopy, the drone lift, and the surrounding research area for equipment inspection, maintenance, and scientific operations, ladders are an essential component of the stern. These ladders are typically installed near the end of the canopy for easy access. Due to heavy snowfall and frequent rain and snow in polar regions, rain and snow easily accumulate on the canopy surface. If this accumulation is not promptly drained, it can increase the vessel's load, cause structural icing, and even damage the canopy and the equipment below. Therefore, a dedicated rainwater drainage device must be installed at the end of the canopy to quickly drain rain and snow, ensuring the vessel's safety and the stable operation of the equipment.

[0003] However, in the existing technology, both need to be arranged in the area at the end of the shield. However, since the space at the stern of polar research vessels is already very limited, arranging both the inherent ladder and the rainwater guiding device at the end of the shield will result in an excessively large space occupied in that area, seriously encroaching on the space for placing scientific research equipment and affecting the normal conduct of scientific research operations. At the same time, the arrangement of the two independent components will interfere with each other. The ladder may block the flow path of the rainwater guiding device, resulting in poor drainage of rain and snow. The rainwater guiding device may also hinder the normal use of the ladder, and even exacerbate the climbing safety hazards of the ladder after rain and snow freeze.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: A semi-concealed stern research area structure for a polar research vessel includes a stern of the research vessel, a cover plate is installed on the deck of the stern of the research vessel, and a research area is formed at the bottom of the cover plate, and the research area is used to place research equipment.

The bottom of the top rod is attached to a guide block installed on the stern of the research vessel. The guide block has a flow guiding surface and a ladder surface, and the ladder surface is higher than the flow guiding surface. When the top rod is in contact with the flow guiding surface, several pairs of sealing plates form a plane and cooperate with the frame for rainwater discharge on the guide shield. When the top rod is in contact with the ladder surface, the top rod retracts and drives the sealing plate to rotate to a horizontal state, and several pairs of sealing plates are in a stepped shape. The swing arm drives the handrail to unfold, making it convenient for users to climb.

[0006] In a preferred embodiment of the present invention, the stern of the research vessel is equipped with a fence, and the fence is also equipped with a buffer rubber pad. A base is bolted to the deck at the stern of the research vessel, and a support column is vertically welded on the base. The top of the support column is installed at the bottom of the cover plate, and the cover plate is W-shaped. The bottom of the bend of the cover plate corresponds to the flow guide surface. When the top rod moves to the flow guide surface, the bend of the cover plate corresponds to the frame.

[0007] In a preferred embodiment of the present invention, a plurality of pairs of keel supports are installed at the bottom of the cover plate. The keel supports are arc-shaped. A fixing sleeve is slidably sleeved on the side wall of the support column, and a crossbeam is welded to the side wall of the fixing sleeve. The fixing sleeve and the side wall of the support column are connected by bolts. A plurality of pairs of drone lifting platforms are installed at the top of the cover plate.

[0009] In a preferred embodiment of the present invention, a positioning frame is installed on the side wall of the synchronization frame, the positioning frame is provided with positioning holes, and a number of pairs of insertion holes are provided on the deck at the stern of the research vessel, the insertion holes corresponding to the positioning holes, and the insertion holes and positioning holes are mutually positioned by pins.

[0010] In a preferred embodiment of the present invention, a through groove is provided at the bottom of the frame, and several pairs of sealing plates are rotatably installed on the side wall of the through groove. A notch is provided at the top of the sealing plate, and a groove is provided at the bottom of the sealing plate. The groove on the upper sealing plate and the groove on the lower sealing plate are adapted to each other, and a sealing gasket is installed on the outer edge of the sealing plate.

[0011] In a preferred embodiment of the present invention, a synchronous shaft is installed at the rotation center of the sealing plate. The synchronous shaft moves through the frame and its end is connected to the rotation center of the swing arm. The side wall of the synchronous shaft is also connected to the rotation center of the swing arm.

[0012] In a preferred embodiment of the present invention, a groove is formed on the surface of the rocker arm, and a slide rod is slidably installed on the groove. The diameter of the slide rod is adapted to the width of the groove. The end of the slide rod is connected to a synchronizing rod. The top rod passes through the side wall of the frame.

[0015] Compared with the prior art, the present invention has the following advantages: This invention utilizes an integrated linkage structure comprised of a sealing plate, rocker arm, synchronizing rod, and guide block. Functional switching is achieved simply by manually pushing the frame along a slide rail on the shield. When the frame is in its initial position, the sealing plates form a flat plane, specifically designed to guide and discharge rainwater and snow from the shield. As the frame moves, the linkage structure operates synchronously, quickly transforming the original guide plane structure into a stepped ladder. This design effectively eliminates the drawbacks of traditional independent ladders at the stern of polar research vessels, which occupy significant deck space and interfere with drainage processes. It significantly simplifies the overall structure of the stern research area, reduces the number of equipment components, and consequently lowers the difficulty of equipment maintenance in harsh environments such as low temperatures and strong winds in polar regions, thus improving the practicality and durability of the device.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention. Example 1:

[0020] like Figures 1 to 11 As shown, a semi-concealed stern research area structure of a polar research vessel includes a stern 1 of the research vessel, a cover plate 2 installed on the deck of the stern 1, and a research area 37 formed at the bottom of the cover plate 2, and the research area 37 is used to place research equipment. A pair of frames 7 are slidably mounted on the cover plate 2, and several pairs of sealing plates 15 are rotatably mounted on each frame 7; A swing arm 19 is installed at the rotation center of the sealing plate 15, and a handrail 20 is rotatably installed at the end of the swing arm 19. A rocker arm 21 is also installed at the rotation center of the sealing plate 15, and a synchronizing rod 23 is slidably installed on the rocker arm 21. A fixing frame 25 is installed at the end of the synchronizing rod 23, and a top rod 26 is installed at the bottom of the fixing frame 25. The bottom of the top rod 26 is attached to the guide block 28 installed on the stern 1 of the research vessel. The guide block 28 has a flow guiding surface 29 and a climbing surface 30, and the climbing surface 30 is higher than the flow guiding surface 29. When the top rod 26 is in contact with the flow guiding surface 29, several pairs of sealing plates 15 form a plane and cooperate with the frame 7 for rainwater discharge on the guide shield 2. When the top rod 26 is in contact with the climbing surface 30, the top rod 26 retracts and drives the sealing plate 15 to rotate to a horizontal state, and several pairs of sealing plates 15 are in a stepped shape. The swing arm 19 drives the handrail 20 to unfold, making it convenient for users to climb.

[0021] like Figures 1 to 11 As shown in the specific embodiment, a fence 36 is installed around the stern 1 of the research vessel, and a buffer rubber pad is also installed on the fence 36. A base 38 is bolted to the deck of the stern 1 of the research vessel, and a support column 3 is vertically welded on the base 38. The top of the support column 3 is installed at the bottom of the cover plate 2, and the cover plate 2 is W-shaped. The bottom of the bend of the cover plate 2 corresponds to the guide surface 29. When the top rod 26 moves to the guide surface 29, the bend of the cover plate 2 corresponds to the frame 7. The fence 36 can effectively protect the staff and prevent them from falling from the stern. The buffer rubber pad can reduce the collision damage between the staff or equipment and the fence 36. The cooperation between the base 38 and the support column 3 provides a stable support for the cover plate 2, ensuring that the cover plate 2 maintains its structural integrity under polar strong wind conditions. The design of the W-shaped cover plate 2, in conjunction with the guide surface 29, can accurately guide the flow of rainwater and snow, improve drainage efficiency, and prevent rain and snow accumulation from damaging the equipment.

[0022] like Figures 1 to 11 As shown, furthermore, several pairs of keel supports 5 are installed at the bottom of the cover plate 2. The keel supports 5 are arc-shaped, and the side walls of the support columns 3 are slidably fitted with fixing sleeves 39. The side walls of the fixing sleeves 39 are welded with crossbeams 4. The fixing sleeves 39 and the side walls of the support columns 3 are connected by bolts. Several pairs of UAV lifting platforms 6 are installed at the top of the cover plate 2. The arc-shaped keel supports 5 can enhance the structural strength of the cover plate 2, distribute the pressure on the cover plate 2, and prevent the cover plate 2 from deforming due to rain and snow accumulation or strong wind impact. The cooperation between the fixing sleeves 39 and the crossbeams 4 can further strengthen the stability of the support columns 3, and at the same time, it is convenient to adjust the height of the crossbeams 4 according to actual needs, improving the structural adaptability. The setting of the UAV lifting platforms 6 can meet the operational needs of UAV exploration in polar scientific expeditions, without the need to build an additional take-off and landing platform, saving tail space. Example 2:

[0023] The difference between the above embodiments and this embodiment is that: Figures 1 to 11 As shown, a slide rail 8 is installed on the cover plate 2, and a slider 9 is slidably installed on the slide rail 8. The slider 9 is connected to the back of the frame 7. A synchronization frame 10 is installed on the back of the frame 7. A guide wheel 11 is installed at the bottom of the synchronization frame 10, and the bottom of the guide wheel 11 is attached to the deck of the stern 1 of the research vessel. A positioning frame 12 is installed on the side wall of the synchronization frame 10. A positioning hole 13 is opened on the positioning frame 12, and several pairs of insertion holes 14 are opened on the deck of the stern 1 of the research vessel. The insertion holes 14 correspond to the positioning holes 13, and the insertion holes 14 and the positioning holes 13 are mutually positioned by pins. The cooperation between the slide rail 8 and the slider 9 enables the frame 7 to slide flexibly, facilitating the switching of the working state of the sealing plate 15 according to operational needs; the guide wheel 11 can reduce frictional loss when the frame 7 slides, ensuring a smooth and stable sliding process and reducing the difficulty of operation; the cooperation between the positioning frame 12, positioning hole 13, insertion hole 14 and the pin can enable the frame 7 to be positioned and fixed at any position, preventing the frame 7 from shifting due to hull turbulence, and ensuring the structural stability of the sealing plate 15 in the climbing or guiding state.

[0024] like Figures 1 to 11 As shown, in a specific embodiment, a through groove 35 is provided at the bottom of the frame 7. Several pairs of sealing plates 15 are rotatably installed on the side wall of the through groove 35. A notch 16 is provided at the top of the sealing plate 15, and a groove 17 is provided at the bottom of the sealing plate 15. The groove 17 on the upper sealing plate 15 and the groove 17 on the lower sealing plate 15 are mutually adapted. A sealing gasket is installed on the outer edge of the sealing plate 15. The through groove 35 provides sufficient space for the rotation of the sealing plate 15. The adaptation of the notch 16 and the groove 17 can improve the sealing performance of the sealing plate 15 after splicing, and prevent rainwater and snow from seeping into the scientific research area 37 from the splicing gaps.

[0025] like Figures 1 to 11 As shown, a synchronous shaft 18 is further installed at the rotation center of the sealing plate 15. The synchronous shaft 18 movably passes through the frame 7, and its end is connected to the rotation center of the swing arm 19. The side wall of the synchronous shaft 18 is also connected to the rotation center of the rocker arm 21. The synchronous shaft 18 realizes the synchronous linkage of the sealing plate 15, the swing arm 19, and the rocker arm 21, ensuring that when the sealing plate 15 flips, the handrail 20 can be opened or retracted synchronously without separate operation, thus improving the ease of operation. At the same time, the setting of the synchronous shaft 18 makes the three movements coordinated and consistent, avoiding problems such as jamming and misalignment, improving the linkage reliability of the structure, and reducing maintenance costs. Example 3:

[0026] The difference between the above embodiments and this embodiment is that: Figures 1 to 11As shown, a slot 22 is formed on the surface of the rocker arm 21, and a slide rod 24 is slidably mounted on the slot 22. The diameter of the slide rod 24 is adapted to the width of the slot 22. The end of the slide rod 24 is connected to the synchronizing rod 23. The top rod 26 is movably connected to the side wall of the frame 7, and a ball bearing 27 is installed at the end of the top rod 26. The cooperation between the slot 22 and the slide rod 24 enables flexible switching between the rotation of the rocker arm 21 and the linear movement of the synchronizing rod 23, ensuring that the movement of the top rod 26 can be accurately transmitted to the rocker arm 21, driving the sealing plate 15 to rotate smoothly. The ball bearing 27 can reduce the friction between the top rod 26 and the guide block 28, avoiding wear between them, while ensuring that the top rod 26 can slide smoothly along all surfaces of the guide block 28, improving the smoothness of state switching.

[0027] like Figures 1 to 11 As shown, in a specific embodiment, a limiting seat 32 is movably installed through the side wall of the synchronizing rod 23. The side wall of the limiting seat 32 is mounted on the frame 7. A limiting plate 33 is installed on the outer side wall of the synchronizing rod 23. A limiting spring 34 is sleeved on the synchronizing rod 23. One end of the limiting spring 34 is engaged with the limiting plate 33, and the other end is engaged with the limiting seat 32. The limiting spring 34 is used to drive the ball bearing 27 to always be in close contact with the surface of the guide block 28. The limiting seat 32 provides guidance for the movement of the synchronizing rod 23, preventing the synchronizing rod 23 from shifting and causing the linkage structure to jam. The limiting spring 34 applies an elastic force to the synchronizing rod 23 through the limiting plate 33, ensuring that the ball bearing 27 is always in close contact with the guide block 28, unaffected by the hull's swaying, ensuring the stability of the sealing plate 15's working state, and improving the reliability of the structure.

[0028] like Figures 1 to 11 As shown, the guide block 28 is further provided with a switching surface 31, which is inclined. One end of the switching surface 31 is connected to the guide surface 29, and the other end is connected to the ladder surface 30. The switching surface 31 is used to connect the guide surface 29 and the ladder surface 30. The inclined switching surface 31 realizes the smooth connection between the guide surface 29 and the ladder surface 30, so that the ball bearing 27 at the end of the push rod 26 can switch smoothly between the two surfaces, avoiding jamming or sticking during the switching process and reducing the difficulty of operation. At the same time, the setting of the switching surface 31 makes the transition between the two working states smoother, reduces the mechanical wear of the linkage structure, and extends the service life of the equipment.

[0029] The implementation principle of the semi-concealed stern research area structure of a polar research vessel according to the present invention is as follows: During the navigation and scientific research operations of the research vessel, the deck at the stern 1 of the research vessel provides stable support for the shield 2 through the base 38 and support column 3. The shield 2 is W-shaped and its bottom is reinforced by the keel support 5. At the same time, the scientific research area 37 formed at the bottom of the shield 2 provides semi-sheltered protection for scientific research equipment, avoiding damage to the equipment caused by the harsh polar environment. The railing 36 around the stern 1 of the research vessel further enhances the safety of the operation. The buffer rubber pads on the railing 36 can reduce collision damage. The UAV lifting platform 6 on the top of the shield 2 can meet the operational needs of UAV exploration in polar scientific research. The fixing sleeve 39 and crossbeam 4 on the support column 3 can further strengthen the support stability of the shield 2 and ensure that it remains structurally intact under harsh weather conditions such as strong polar winds.

[0030] The frame 7 on the cover plate 2 slides with the slide rail 8 via the slider 9, allowing the position of the frame 7 on the cover plate 2 to be adjusted according to the needs of scientific research operations. After adjustment, the frame 7 is positioned and fixed by aligning the positioning hole 13 on the positioning frame 12 with the insertion hole 14 on the deck of the stern 1 of the research vessel and inserting a pin. The guide wheel 11 at the bottom of the synchronous frame 10 assists the frame 7 to slide smoothly and reduces friction loss during the sliding process. The through groove 35 at the bottom of the frame 7 provides space for the installation and rotation of the sealing plate 15. The sealing plate 15 is rotatably mounted on the side wall of the through groove 35 via the synchronous shaft 18. The synchronous shaft 18 is connected to the swing arm 19 and the rocker arm 21 to achieve synchronous rotation of the three. The sealing gasket on the outer edge of the sealing plate 15 and the fit between the upper and lower adjacent sealing plates 15 through the notch 16 and the groove 17 can improve the sealing effect and prevent rainwater, snow, etc. from entering the scientific research area 37.

[0031] The slot 22 on the rocker arm 21 slides with the slide bar 24, so that when the rocker arm 21 rotates, it can drive the synchronizing rod 23 to move linearly. The limiting seat 32 on the side wall of the synchronizing rod 23 guides the movement of the synchronizing rod 23. The limiting spring 34 applies an elastic force to the synchronizing rod 23 through the limiting plate 33, ensuring that the ball 27 at the end of the push rod 26 is always in close contact with the surface of the guide block 28, and preventing the push rod 26 from disengaging from the guide block 28 due to the hull's turbulence.

[0032] The guide surface 29, switching surface 31, and ladder surface 30 on the guide block 28 work together to achieve flexible switching between two working states of the sealing plate 15 (where the ladder state is the initial state): When the research vessel is docked and staff need to climb to the UAV lift platform 6 for equipment maintenance and scientific research, the frame 7 is in its initial positioning position. At this time, the top rod 26 is in contact with the ladder surface 30 of the guide block 28. Under the action of the limit spring 34, the top rod 26 is in a retracted state and pulls the synchronous rod 23 to move. The synchronous rod 23 drives the rocker arm 21 to rotate through the slide rod 24. The rocker arm 21 drives the sealing plate 15 to rotate to a horizontal state through the synchronous shaft 18. At the same time, the synchronous shaft 18 drives the swing arm 19 to rotate. The handrail 20 at the end of the swing arm 19 unfolds accordingly. Several pairs of horizontal sealing plates 15 are distributed in a stepped manner, which cooperates with the unfolded handrail 20 to form a stepped structure that is convenient for staff to climb. Staff can use this stepped structure to safely climb to the designated position for work (the ladder position can be adjusted by pushing the frame 7 along the slide rail 8, or the frame 7 can be moved as a whole by external equipment).

[0033] In rainy or snowy weather, when drainage is needed, the frame 7 is pushed to slide in the opposite direction along the slide rail 8. The frame 7 drives the synchronous rod 23 and the push rod 26 to move synchronously, so that the ball 27 at the end of the push rod 26 slides along the ladder surface 30 of the guide block 28 through the switching surface 31 to the guide surface 29. Since the height of the ladder surface 30 is higher than that of the guide surface 29, the ball 27, under the support of the guide surface 29, drives the push rod 26 to extend downward. The push rod 26 pushes the synchronous rod 23 to move, and the synchronous rod 23, through the slide rod 24, carries... The rocker arm 21 rotates in the opposite direction. The rocker arm 21 drives the sealing plate 15 to rotate and splice through the synchronous shaft 18 to form a flat plane. This plane cooperates with the W-shaped shield 2. The bottom of the bend of the shield 2 corresponds to the guide surface 29, which can guide the rainwater and snow on the shield 2 to the guide surface 29 for rapid discharge and prevent the rainwater and snow from accumulating on the shield 2. At the same time, the plane formed by the sealing plate 15 can further enhance the shielding effect of the shield 2 and protect the equipment in the scientific research area 37. When the work is completed or when climbing is required again, push the frame 7 to reset. The ball bearing 27 at the end of the top rod 26 returns to the climbing surface 30 along the guide surface 29 and the switching surface 31. The top rod 26 retracts and resets under the action of the limit spring 34, causing the sealing plate 15 to rotate in the opposite direction and form a stepped shape. The handrail 20 retracts with the swing arm 19 and returns to the initial climbing state, thereby realizing the flexible switching of the functions of shelter protection, rainwater drainage and personnel climbing in the scientific research area 37, which is suitable for the complex operation requirements of polar scientific research.
