Description

Technical Field

[0001] The present application relates to the technical field of ship components, and more particularly to a multifunctional guardrail used on a yacht. Background Art

[0002] With the improvement of people's living standards and the pursuit of high-quality life, personal or public yachts are becoming more and more popular. However, since yachts are in a humid and high-salt environment, the guardrails installed on the yacht deck should not only block tourists, but also protect tourists with more functions.

[0003] The prior art publication number CN111959682A discloses that the present invention provides a corrosion-resistant stainless steel multifunctional guardrail for yachts, including a column assembly, an elbow assembly, a surface pipe assembly, a cross pipe assembly, and a clean water flushing assembly. The whole adopts stainless steel welding-free technology, and all are assembled in a connector manner, which can avoid the rust problem caused by the presence of welding points in the pipe connection, and creatively adds an automatic clean water flushing device, which can absorb seawater on site without carrying a water source, and purifies water into pure water through the reverse osmosis principle, so as to achieve long-term exposure of the guardrail to the salt components of seawater.

[0031] See also Figure 1-Figure 8 ,This application provides a technical solution:

[0032] refer to Figure 1 , Figure 2 and Figure 3 A protective vertical rod 3 is fixedly connected to the middle of the bottom end of the upper cross bar 1, an upper fixed plate 31 is fixedly connected to the top of the protective vertical rod 3, and a lower fixed plate 32 is fixedly connected to the bottom end of the protective vertical rod 3. The upper fixed plate 31 and the lower fixed plate 32 have the same internal structure. Both the upper fixed plate 31 and the lower fixed plate 32 are set as long plates, and the two sides of the long plates are set as arcs;

[0033] The top of the upper fixed plate 31 is connected to the position adjustment structure 6, which is composed of a rope 61, a rotating shaft 62, a first bevel gear 63 and a motor 64. The top of the upper fixed plate 31 is fixedly connected to multiple groups of ropes 61, and the multiple groups of ropes 61 are evenly arranged on the top of the upper fixed plate 31. The force transmitted by the upper fixed plate 31 is evenly distributed to each rope 61, so as to avoid the rope 61 being broken and unable to be used normally due to a single force. In addition, when one of the ropes 61 is broken, the force on the upper fixed plate 31 is dispersed to the remaining ropes 61, without affecting the operation. For the purpose of normal use of the ring device, the rope 61 is wound around the outside of the rotating shaft 62, and the rotating shaft 62 rotates to retract and release the rope 61. Both ends of the rotating shaft 62 are fixedly connected with the first bevel gear 63. The rotation of the first bevel gear 63 drives the rotating shaft 62 to rotate. The other side of the first bevel gear 63 is fixedly connected to the output end of the motor 64. The forward and reverse rotation of the motor 64 drives the first bevel gear 63 to rotate forward and reversely. The forward and reverse rotation of the first bevel gear 63 drives the rotating shaft 62 to rotate forward and reversely. The forward and reverse rotation of the rotating shaft 62 drives the outer rope 61 to be wound around the rotating shaft 62 or to be wound off the rotating shaft 62.

[0034] The bottom end of the position adjustment structure 6 is symmetrically provided with two linkage structures 7. The linkage structure 7 is arranged on the inner side of the side vertical rod 2. The inner side vertical rod 2 is provided with a circular groove 21 that is convenient for the rotation of the linkage structure 7. The linkage structure 7 is composed of a second bevel gear 71, an upper clamping plate 72, a connecting rod 73 and a lower clamping plate 74. The second bevel gear 71 is meshed and connected with the bottom end of the first bevel gear 63, and the rotation of the first bevel gear 63 can drive the second bevel gear 71 to rotate. The second bevel gear 71 is fixedly connected to the top of the upper clamping plate 72, and the second bevel gear 71 can drive the upper clamping plate 72 to rotate. The bottom end of the upper clamping plate 72 is fixedly connected to the connecting rod 73. The rotation of the upper clamping plate 72 can drive the connecting rod 73 to rotate. The bottom end of the connecting rod 73 is fixedly connected to the lower clamping plate 74. The rotation of the connecting rod 73 can drive the lower clamping plate 74 to rotate, so that the linkage structure 7 as a whole can freely rotate on the inner side of the side vertical rod 2 under the action of the position adjustment structure 6, thereby achieving the purpose of one power source driving the two structures to move synchronously at the same time, thereby improving the linkage between the device structures;

[0035] When the locking cam 72 is in the locked state, the locking cam 728 can be used to lock the locking cam 74 in the locking cam 76. When the locking cam 72 is in the locked state, the locking cam 74 can be used to lock the locking cam 76 with the other end of the locking cam 74.

[0036] The motor 64 rotates in the reverse direction to drive the first bevel gear 63, and the first bevel gear 63 reverses to drive the shaft 62 to rotate in the reverse direction. The shaft 62 reverses to wind the rope 61 around the shaft 62, and the rope 61 drives the upper fixed plate 31 fixed thereto to move upward, and the upper fixed plate 31 drives the protective vertical rod 3 and the lower fixed plate 32 to move upward. At the same time, the first bevel gear 63 reverses to drive the second bevel gear 71 reverses, and the second bevel gear 71 reverses to drive the upper clamping plate 72, the connecting rod 73 and the lower clamping plate 74 to rotate in the reverse direction. The size of the lower fixed plate 32 is larger than that of the upper fixed plate 31, and the size of the upper clamping plate 72 is larger than that of the lower clamping plate 74. When the locking cam 73 is in the unlocked position, the locking cam 73 will be in the unlocked position, and the locking cam 73 will be in the unlocked position when the locking cam 73 is unlocked.

[0037] refer to Figure 2 , Figure 3 and Figure 8 The lower fixed plate 32 is slidably connected to the inner side of the lower cross bar 4, and a slide groove 41 is opened at the bottom end of the lower cross bar 4. In the initial state, the lower fixed plate 32 is fixed in the slide groove 41 of the lower cross bar 4. When in the expanded state, the lower fixed plate 32 moves along the slide groove 41. The size of the slide groove 41 is larger than the size of the upper fixed plate 31 and the lower fixed plate 32. The protective vertical rod 3 can move freely in the lower cross bar 4, and the protective vertical rod 3 slides in the slide groove 41. The two ends of the lower cross bar 4 are fixedly set at the bottom end of the side vertical rod 2.

[0038] refer to Figure 3 , Figure 5 , Figure 6 and Figure 7 The inner sides of the upper fixing plate 31 and the lower fixing plate 32 are fixedly connected to the bottom end of one side of the folded and stored inflatable lifebuoy 33. The folding and storage method refers to the aircraft life-saving slide in the prior art. The inner layer of the inflatable lifebuoy 33 is a polyurethane that can block air, and the outer layer of the lower fixing plate 32 is a flame retardant coating. A compressed gas cylinder 35 is arranged at the bottom end of the inner side of the upper fixing plate 31 and the lower fixing plate 32. The outer side of the compressed gas cylinder 35 is connected to the bottom end of the inflatable lifebuoy 33 through a connecting pipe 34. A valve switch 36 is arranged on the outer side of the compressed gas cylinder 35. The valve switch 36 is meshed with the tooth plate 75 in the initial state. The tooth plate 75 is fixedly connected to the top of the upper clamping plate 72 and the lower clamping plate 74. The upper clamping plate 72 is initially engaged with the limit grooves 39 on both sides of the bottom end of the upper fixing plate 31, and the lower clamping plate 74 is initially engaged with the lower fixing plate 31. The limit grooves 39 on both sides of the bottom end of the plate 32 are engaged and connected. When the upper clamping plate 72 and the lower clamping plate 74 rotate, the tooth plate 75 is driven to rotate, and the tooth plate 75 drives the valve switch 36 to rotate. The valve switch 36 is started to release the compressed air inside the compressed gas cylinder 35, and the compressed air is transmitted to the inner side of the inflatable lifebuoy 33 through the connecting pipe 34. The cover plate 38 rotatably connected to the middle part of the upper fixed plate 31 and the lower fixed plate 32 on both sides is impacted by the force, and the cover plate 38 is opened. After the inflatable lifebuoy 33 expands to several times its size, the valve switch 36 is closed, and the inflated inflatable lifebuoy 33 and the upper fixed plate 31 form an H-shaped lifesaving platform. A venting port 37 is provided on one side of the inflatable lifebuoy 33. The venting port 37 is opened to discharge the gas in the inflatable lifebuoy 33 and store the inflatable lifebuoy 33 into the upper fixed plate 31.

[0039] refer to Figure 1 , Figure 2 and Figure 4 A button 9 is arranged on the outside of the upper cross bar 1, and the button 9 is electrically connected to the driving switch of the position adjustment structure 6 on the inner side of the upper cross bar 1 through the control center. The side vertical rods 2 are fixedly connected to both sides of the bottom end of the upper cross bar 1, and the bottom ends of the side vertical rods 2 are fixed to the side of the yacht. A sensor 5 is fixedly arranged on the bottom end of the outer side of the side vertical rod 2, and the sensor 5 is electrically connected to the driving switch of the position adjustment structure 6 through the control center. The control center can collect and feedback information through manual pressing of the button 9 and identification sensing of the sensor 5. After receiving the information, the control center can control the opening of the device driving component, so as to achieve the purpose of immediate rescue of the fallen person by directly pressing the button 9 when the personnel on the yacht find that someone has fallen into the water unexpectedly, and in the case that no one finds that the person has fallen from the yacht, the rescue can also be started after the sensor 5 automatically identifies and senses, so as to avoid casualties caused by no one finding out, and the normal use of the device under different circumstances can be achieved.

[0040] When the life buoy on the yacht is damaged or insufficient in number and cannot rescue the person who falls near the yacht, first the button 9 identifies the person in need of rescue or other people on the yacht find the person asking for rescue and press the button 9, and the information feedback from the control center causes the motor 64 to start, and the motor 64 starts to drive the first bevel gear 63 to rotate, and the rotation of the first bevel gear 63 drives the rotating shaft 62 to rotate, and the rotation of the rotating shaft 62 gradually releases the rope 61. At the same time, the rotation of the first bevel gear 63 drives the second bevel gear 71 to rotate, and the rotation of the second bevel gear 71 drives the upper clamping plate 72, the connecting rod 73 and the lower clamping plate 74 to rotate synchronously, and the upper clamping plate 72 and the lower clamping plate 74 rotate in the circular groove 21 of the side vertical rod 2, and no longer clamp with the bottom end of the upper fixing plate 31 and the lower fixing plate 32 The upper and lower fixing plates 31 and 32 are closed at this time. There is no support at the bottom ends of the upper fixing plate 31 and the lower fixing plate 32. The upper and lower fixing plates 31, 32 and the protective vertical rod 3 slide down from the slide groove 41 provided at the lower cross bar 4 under the action of gravity. At this time, the upper and lower clamping plates 72 and 74 rotate to start the valve switch 36. Referring to the prior art such as the aircraft life-saving slide, the valve switch 36 is started so that the compressed air in the compressed gas cylinder 35 is poured into the inflatable lifebuoy 33 through the connecting pipe 34. The inflatable lifebuoy 33 changes from the initial compressed state to a several times larger expanded state. The inflatable lifebuoy 33 drives the lower and upper fixing plates 32 and the upper fixing plates 31 and the protective vertical rod 3 to form an H-shaped life-saving platform. The valve switch 36 is closed accordingly. The large space is convenient for multiple people to rescue, and it also improves the comfort of the rescued personnel and avoids unnecessary physical exertion.

[0041] After the rescued person climbs onto the lifesaving platform, the motor 64 rotates in the opposite direction to wrap the rope 61 around the rotating shaft 62. The rope 61 drives the protective vertical rod 3 to move, pulling the rescued person to the side of the yacht to complete the rescue. Then the air vent 37 is released, and the air is discharged from the air vent 37. The inflatable life buoy 33 is folded and stored inside the upper fixing plate 31 and the lower fixing plate 32, which is convenient for normal use next time and avoids oxidation damage caused by the outdoor environment.

[0042] refer to Figure 2 and Figure 7The inner side of the lower cross bar 4 is provided with a water absorbing structure 8 for wiping and absorbing water from the recovered protection vertical rod 3. The water absorbing structure 8 specifically includes a plurality of symmetrically arranged fixing springs 82 fixed to the inner side of the lower cross bar 4, and a clamping block 81 is fixedly connected to the other side of the fixing spring 82. The fixing spring 82 can limit the position of the clamping block 81 to ensure that the clamping block 81 is tightly fitted with the outer surface of the wiping protection vertical rod 3 and the rope 61 when the protection vertical rod falls to the water surface, and the clamping block 81 can fix the outer side of the rope 61 when the protection vertical rod falls to the water surface, ensuring that there is still a corresponding protection structure when the protection vertical rod 3 is not in position, so as to avoid accidental falling of people on the yacht while rescuing personnel, and a water absorbing layer 83 is arranged on the inner side of the clamping block 81. The clamping block 81 is composed of two symmetrically arranged semicircular rings, and the clamping block 81 can wipe the outer side of the cylindrical protection vertical rod 3 and the outer side of the rope 61. At the same time, the wiping of the clamping block 81 can smooth the burrs on the surface of the rope 61 that is wet with water in the same direction, so as to avoid injuring the rescue personnel when it is used next time.

[0043] The protective vertical rod 3 continues to rise under the restriction of the slide groove 41, and the block 81 elastically changes in the order of the rope 61, the upper fixed plate 31, and the protective vertical rod 3 under the restriction of the fixed spring 82. The water-absorbing layer 83 in the block 81 fits tightly with the rope 61 and the outer side of the cylinder of the protective vertical rod 3 to squeeze and absorb the contaminated moisture, and the moisture falls from the slide groove 41, avoiding damage to the device due to moisture accumulation and increasing the service life of the device.

[0044] Although examples of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
