Description

Technical Field

[0001] This invention belongs to the field of marine storage equipment, and specifically relates to a marine folding curtain storage device. Background Technology

[0002] An underwater curtain is a device installed during waterway dredging operations to protect the underwater ecosystem. Its working principle is to block or reflect the shock waves generated during underwater blasting, thereby reducing the damage to underwater organisms.

[0003] Underwater curtains are divided into bubble curtains and wave-damping curtains. Among them, wave-damping curtains have become the mainstream curtains due to their low production cost and strong wave-damping ability. In order to facilitate the taking down of the curtain, the frame of the curtain is usually designed to be foldable. When in use, it is unfolded manually on the deck of the ship and then deployed by a crane. When taking down, it is also folded manually on the deck and then stored in a storage box or a designated storage area on the deck of the ship by a crane.

[0004] However, the above-mentioned process of folding and storing the curtain requires a lot of manpower and is seriously inefficient. Moreover, when the curtain is lowered into the storage box by a crane, the hull of the blasting vessel is in a water environment and the wind and waves will cause the hull to sway. Whether it is vertical or horizontal lifting, the swing amplitude of the lifting rope is relatively large. Therefore, it is necessary to manually assist the crane to put the folded curtain into the opening of the storage box. This process is not only inefficient but also very unsafe.

[0016] Preferably, in the above technical solution, a plurality of intersecting reinforcing ribs are provided on the first outer side and the second outer side.

[0017] Compared with existing technologies, the present invention has the following advantages: 1. The marine folding curtain retraction device of the present invention has a roller shutter door on the box body and a chain hook installed at the moving end of the roller shutter door. When the roller shutter door is opened, the chain hook can simultaneously pull the folding curtain or other objects suspended on the hook from the passage to the retraction cavity, which is highly efficient and safe. Furthermore, the box body is installed on the ship deck through a linkage drive assembly and a base. The linkage drive assembly can drive the box body to unfold in the vertical direction and fold in the horizontal direction, thereby meeting the needs of different lifting postures, freeing up manpower and improving retraction efficiency.

[0018] 2. The first outer side and the second outer side of the present invention are respectively provided with a drain outlet. When the curtain or other underwater tools are lifted out of the water, water will continuously fall. The water can be guided from the water guide to the drain outlets on both sides to the outside of the box to prevent water accumulation.

[0019] 3. The bend of the slide in this invention is an arc-shaped structure, and a rotatable pulley is provided at the end of the roller shutter door. This not only serves to fix the end of the roller shutter door, but also provides a better guiding effect, making the roller shutter door smoother when opening and closing.

[0020] 4. The other end of the roller shutter door in this invention is provided with an end plate, which not only provides a certain buffer protection for the end of the roller shutter door, but also connects to the chain hook through a rotatable connecting shaft, which serves to fix the chain hook and ensure a certain degree of reliability. The rotatability of the roller shaft also provides a certain degree of rotational flexibility for the chain hook.

[0021] 5. The guide groove in this invention has a V-shaped structure, which can guide the chain of the chain hook after the roller shutter door is placed in the interlayer, so that the chain hook has higher stability when pulling objects. Furthermore, a guide wheel is provided below the guide groove, which can support the chain of the chain hook and prevent the chain of the chain hook from directly contacting the bottom of the guide groove and getting stuck.

[0022] 6. The clearance groove on the second back plate of the present invention allows for easy disassembly of the chain hook after the object is pulled into the receiving cavity, and allows the chain hook to be placed outside the box. When the roller shutter door is closed, the chain hook can always move with the outside of the roller shutter door until the roller shutter door is closed. The bottom of the clearance groove is relatively wide, which also facilitates the removal of the chain hook.

[0023] 7. The second outer surface of the present invention is provided with multiple intersecting reinforcing ribs, which form a triangular frame structure, thus ensuring the strength of the entire box with less material and weight. Attached Figure Description

[0036] The housing 100 has a rectangular parallelepiped structure, with an internal storage cavity 110 and a drive cavity 170. The storage cavity 110 is located above the drive cavity 170. A passageway 120 communicating with the storage cavity 110 is provided on one side of the housing 100, extending to the top of the housing 100. The top of the housing 100 is arc-shaped. The side of the housing 100 also has a first outer surface 130 and a second outer surface 140, which are parallel to each other, with the passageway 120 located between them. Multiple outwardly protruding reinforcing ribs 900 intersecting each other are provided on the first outer surface 130 and the second outer surface 140. The reinforcing ribs 900 form a triangular mesh structure; a roller shutter 200 is installed at the passage 120, and a roller 150, which is an electric roller, is installed inside the drive cavity 170. One end of the roller shutter 200 is fixedly connected to the side of the roller 150; a first back plate 600 and a second back plate 700 are provided on the opposite side of the housing 100. The first back plate 600 and the second back plate 700 are parallel to each other. The first back plate 600 is opposite to the passage 120, and there is a certain distance between the first back plate 600 and the second back plate 700 to form a sandwich 800. The bottom of the sandwich 800 is connected to the drive cavity 170, and an inclined guide is provided between the sandwich 800 and the drive cavity 170. A sliding groove 121 is provided on both sides of the passage 120. One end of the sliding groove 121 extends to the top of the interlayer 800 and communicates with it. The width of the sliding groove 121 is consistent with the thickness of the interlayer 800. The bend of the sliding groove 121 is arc-shaped, consistent with the top shape of the box 100. An end plate 220 is fixedly installed at the other end of the roller shutter door 200. A pulley 210 is installed on both sides of the end plate 220. The axle of the pulley 210 is perpendicular to the bottom of the sliding groove 121, so that the pulley 210 can roll along the sliding groove 121. A clearance opening 230 is opened in the middle of the end plate 220. A rotatable connecting shaft 2 is installed in the clearance opening 230. 40. One end of the chain portion of the chain hook 300 is fixedly connected to the connecting shaft 240 and can rotate with the connecting shaft 240. The other end of the chain hook 300 is provided with a hook body 310. The chain portion of the chain hook 300 and the end plate 220 can both pass through the interlayer 800. The diameter of the hook body 310 is larger than the gap of the interlayer 800. A magnet or hook can be installed on the hook body 310 so that it can be temporarily fixed to the outside of the roller shutter door 200 in a detachable manner. When the roller 150 rolls up the roller shutter door 200, the roller shutter door 200 will open the passage 120. Then the end plate 220 can drive the chain portion of the chain hook 300 to be retracted into the interlayer 800, thereby pulling the hook body 310 into the retraction cavity 110.

[0037] In addition, a guide groove 610 is provided on the first back plate 600. The guide groove 610 has a "V" structure. One end of the guide groove 610 faces upward and forms a first opening 620 at the edge of the first back plate 600. The other end of the guide groove 610 faces downward and gradually narrows in width and has an arc-shaped structure. A rotatable guide wheel 630 is also provided on the first back plate 600. The guide wheel 630 is positioned corresponding to the other end of the guide groove 610 and its rotation axis is consistent with the width direction of the guide groove 610. When the end plate 220 moves into the interlayer 800 along with the other end of the roller shutter door 200, the chain part of the chain hook 300 can abut against the top side of the guide wheel 630.

[0038] Meanwhile, a clearance groove 710 is also provided on the second back plate 700. One end of the clearance groove 710 faces upward and forms a second opening 720 at the edge of the second back plate 700. The other end of the clearance groove 710 faces downward and is lower than the other end of the guide groove 610. The other end of the clearance groove 710 is also an arc-shaped structure, and its width is greater than the width of the other end of the guide groove 610.

[0039] In addition, a drain outlet 160 is provided on the first outer side 130 and the second outer side 140 respectively. The two drain outlets 160 are positioned opposite each other and are simultaneously connected to the bottom of the receiving cavity 110. A water guiding part 161 is provided at the bottom of the receiving cavity 110. The middle part of the water guiding part 161 arches upward from the bottom of the receiving cavity 110. The two ends of the water guiding part 161 extend toward the bottom edge of the drain outlet 160 and slope downward. The water guiding part 161 is covered with rubber material, which can play the role of waterproofing and increasing the contact friction coefficient.

[0040] The marine folding curtain storage device in this embodiment also includes a base 400, the bottom of which is a mounting surface 410 for mounting to the deck of the blasting vessel. The base 400 is connected to the first outer surface 130 via a linkage drive assembly 500. The linkage assembly includes a connecting seat 420, a first transverse link 430, a second transverse link 440, a first longitudinal link 450, a second longitudinal link 460, and a hydraulic cylinder 470. The connecting seat 420 is fixedly mounted on the base 400, and its two ends are hinged to one end of the first longitudinal link 450 and one end of the second longitudinal link 460, respectively. The length of the first longitudinal link 450 is greater than the length of the second longitudinal link 460. One end of the first transverse link 430 is hinged to the other end of the second longitudinal link 460, and the middle part of the first transverse link 430 is hinged to the middle part of the first longitudinal link 450. One end of the second transverse link 440 is hinged to the first longitudinal link 450. The other end is hinged, and the other end of the first horizontal connecting rod 430 and the other end of the second horizontal connecting rod 440 are simultaneously hinged to the first outer surface 130, and the hinge point of the other end of the first horizontal connecting rod 430 is located below the hinge point of the other end of the second horizontal connecting rod 440; the fixed end of the hydraulic cylinder 470 is rotatably connected to the hinge shaft of one end of the first longitudinal connecting rod 450, and the telescopic end of the hydraulic cylinder 470 is rotatably connected to the hinge shaft of the other end of the second longitudinal connecting rod 460. When the telescopic end of the hydraulic cylinder 470 retracts, the first longitudinal connecting rod 450 and the first horizontal connecting rod 430 are in a mutually perpendicular state. At this time, the box 100 is away from the base 400 and is in an unfolded state and is perpendicular to the mounting surface 410; when the telescopic end of the hydraulic cylinder 470 extends outward, the first longitudinal connecting rod 450 and the first horizontal connecting rod 430 are in a mutually parallel state. At this time, the box 100 folds upward toward the base 400 and is parallel to the mounting surface 410.

[0041] Next, the working principle of a marine folding curtain storage device in this embodiment will be described in detail to enable those skilled in the art to better understand the present invention: When it is necessary to retract the suspended curtain, firstly, the housing 100 is unfolded from the base 400 via the linkage drive assembly 500, at which point the housing 100 is in a vertical position. Then, the hook 310 of the chain hook 300 is attached to the folding ring of the folding curtain. For some curtains that have already been folded, the hook 310 can be hooked to the lower side of the folding curtain. Then, the roller 150 is activated to retract the roller shutter 200. As the roller shutter 200 is retracted into the interlayer 800, the chain portion of the chain hook 300 extends from the bottom of the guide groove 610 and rests on the guide wheel 630 to pull the suspended curtain. At the same time, the crane operator will operate the hook. The curtain is pulled into the inlet 120 to be hoisted relatively smoothly into the receiving chamber 110. If the curtain has folding rings, the rings can be pulled to automatically fold the curtain. After the curtain is fully inside the receiving chamber 110, the staff removes the hook 310 from the curtain through the clearance groove 710, and then slides the hook 310 out from the outside of the second back plate 700. Finally, the roller shutter door 200 is closed, and the hook 310 is attached to the outside of the roller shutter door 200 near the end plate 220 or on the end plate 220, so that the hook 310 will not affect the lifting of materials inside the receiving chamber when it is opened next time.

[0042] In summary, the marine folding curtain storage device in this embodiment features a roller shutter door 200 on the housing 100 and a chain hook 300 installed at the moving end of the roller shutter door 200. When the roller shutter door 200 is open, the chain hook 300 can simultaneously pull the folding curtain or other objects suspended on the hook from the passage 120 into the storage cavity 110, which is both efficient and safe. Furthermore, the housing 100 is mounted on the ship's deck via a linkage drive assembly 500 and a base 400. The linkage drive assembly 500 can drive the housing 100 to unfold vertically and fold horizontally, thereby meeting different hoisting posture requirements, freeing up manpower, and improving storage efficiency.
