Description

Technical Field

[0001] This invention relates to the field of lifeboat rack technology, and particularly to lifeboat racks and their usage methods. Background Technology

[0002] A lifeboat is a small, specialized lifeboat installed on a ship for rescuing crew members in the event of a shipwreck. It is propelled by oars, sails, or motors. Lifeboats are typically equipped with air tanks to ensure sufficient buoyancy even after flooding, guaranteeing the safety of the lifeboat and its crew. Lifeboats on ocean-going vessels also carry a certain amount of fresh water, food, and supplies. However, lifeboats are usually stored on lifeboat racks, and existing racks cannot effectively prevent rusting of the lifeboats or protect the racks themselves during storage.

[0003] Existing devices cannot prevent rust from forming or treat rust when lifeboats are placed on the shelf for extended periods, nor can they protect the lower surface of the shelf from impacts and friction with the ground when lifeboats are placed on the shelf surface, thus avoiding wear and tear that could reduce the shelf's lifespan. Therefore, this application provides a lifeboat shelf to meet these needs. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a lifeboat shelf, which solves the problems that existing devices cannot prevent rust when lifeboats are placed on the shelf for extended periods, facilitate cleaning when rust appears, or protect the lower surface of the shelf when lifeboats are placed on it.

[0006] (II) Technical Solution

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] A lifeboat rack includes a rack, a movable frame slidably connected inside the rack, a connecting pipe inserted inside the movable frame, a material box inserted into the upper surface of the movable frame, a discharge pump inside the material box, a hose inserted into one side of the discharge pump, a push rod inserted into one side of the movable frame, a storage box inserted into one side of the rack, a handle inside the storage box, a telescopic rod slidably connected inside the handle, a compression spring inserted inside the telescopic rod, a button inserted into one end of the compression spring, a roller inserted into one side of the telescopic rod, a lead screw motor inserted inside the rack, a lead screw inserted into one end of the lead screw motor, a friction block slidably connected inside the rack, and a slider inserted into the lower surface of the movable frame.

[0009] Preferably, the number of connecting pipes is two and they are in opposite directions. The lower end of the connecting pipe can be connected to a hose, and a hole is provided on one side of the movable frame so that the lower part of the connecting pipe can be inserted into it.

[0010] Preferably, the shelf has a sliding groove inside to accommodate a lead screw motor and a lead screw, and allows the friction block to move inside. There are two friction blocks, which are located in slots in the middle part of the shelf and are in opposite directions. One side of the friction block has a threaded hole, which allows the lead screw to drive the friction block to move horizontally within the sliding groove.

[0011] Preferably, the shelf is internally fitted with a slide rail, and the lower surface of the shelf is fitted with a partition.

[0012] Preferably, a return spring is inserted into the lower surface of the partition, one end of the return spring is inserted into a support plate, and an airbag is inserted into the inside of the support plate.

[0013] Preferably, an air pump is inserted inside the support plate, an air outlet pipe is inserted at one end of the air pump, and a plug is inserted at one side of the airbag.

[0014] Preferably, a lifting frame is inserted into one side of the shelf, and a drive motor is installed inside the lifting frame.

[0015] Preferably, a lifting screw is inserted into one end of the drive motor, a lifting rod is slidably connected inside the lifting frame, a protective pad is inserted into the lower surface of the lifting rod, a drive groove is opened on one side of the shelf, and a driver is inserted into the drive groove.

[0016] Preferably, a motor base is inserted into one side of the shelf, a rotating motor is inserted into the motor base, a rotating rod is inserted into one end of the rotating motor, a blocking block is slidably connected to the upper surface of the shelf, and a locking block is inserted into one side of the blocking block.

[0017] The method for using lifeboat racks includes the following steps:

[0018] Step 1: Spray the rust inhibitor from inside the tank into the connecting pipe through the discharge pump and hose, and then spray the rust inhibitor onto the surface of the lifeboat to prevent rust.

[0019] Step 2: The staff manually pushes the moving frame to spray the rust inhibitor from the connecting pipe onto the surface of the lifeboat placed on the shelf, thereby spraying the rust inhibitor evenly.

[0020] Step 3: Adjust the length of the telescopic rod inside the handle by manually pressing the button to remove the roller and place it into the shelf at an angle. Repeatedly pull the roller in and out to apply rust inhibitor to the lifeboat.

[0021] Step 4: By starting the lead screw motor and the lead screw, the friction block is repeatedly rubbed against the surface of the lifeboat, thereby reducing rust when it appears on the lifeboat.

[0022] Step 5: By using a return spring and airbag, the shelf can be lowered twice with cushioning during the placement of the lifeboat, thereby reducing wear and tear caused by the impact between the shelf and the ground.

[0023] Step Six: Inflate the airbag using an air pump and air outlet pipe to provide a second buffer when the shelf contacts the support plate. Then, manually remove the plug to deflate the airbag, making it easy to remove for repair or replacement.

[0024] Step 7: By driving the motor to rotate the lifting screw, the lifting rod is lowered from inside the lifting frame to support one side of the shelf, making it easier for the lifeboat to slide out from the shelf surface. The protective pad can protect the bottom of the lifting rod when it is lowered and in contact with the ground.

[0025] Compared with the prior art, the present invention has at least the following beneficial effects:

[0026] The above scheme is implemented through settings.

[0027] The discharge pump and hose effectively prevent rust from forming on the surface of the lifeboats, avoiding rust caused by prolonged disuse. Buttons and compression springs allow for adjustable telescopic rod length, preventing inconvenience due to excessively short rods. Rollers facilitate even application of rust inhibitor to the lifeboat surface, preventing uneven application and localized rusting. A push rod and slider move the entire movable frame within the shelf, allowing the connecting pipe to evenly spray rust inhibitor onto the lifeboat, preventing uneven spraying due to excessive lifeboat length. Regarding the rust inhibitor, the screw motor and screw mechanism allow for repeated rubbing to reduce rust on the lifeboat surface, preventing reduced lifeboat life due to unremovable rust. The lever allows staff to easily and repeatedly push and pull the rollers to evenly apply the rust inhibitor to the lifeboat surface, avoiding the inconvenience of applying the inhibitor due to the rollers' inability to move. The return spring and support plate provide cushioning and shock absorption when the lifeboat is placed on the ground, preventing excessive pressure on the lower surface of the equipment due to the lifeboat's weight.

[0028] The partitions protect the lower surface of the rack, preventing damage when the rack descends and contacts the support plate during lifeboat placement. The air pump and exhaust pipe provide secondary cushioning during lifeboat placement, preventing damage when the rack and partition descend under increased weight. This avoids the initial impact when the return spring fails to provide sufficient cushioning. The plug allows for easy airbag removal when the airbag needs replacing, preventing airbag retraction issues. Finally, the drive motor and lifting screw lower the lifting rod to elevate one side of the equipment when the lifeboat is being lowered, facilitating its sliding off the rack and eliminating the need for manual intervention by personnel. The system addresses the issue of using a crane to lift lifeboats and lower them into the water. A protective pad supports one side of the entire system, protecting the lower surface of the lifting boom and preventing damage from repeated use due to friction with the ground. The rotating motor and boom allow for easy access when storing lifeboats; the bottom of the lifeboat is secured inside the shelf, and when lowering it from the shelf, the blocking block rotates to one side of the shelf and falls into a slot, facilitating easy sliding out. This prevents lifeboats from slipping or derailing when stored inside the shelf, and avoids the inability to slide out easily. A locking block ensures the lifeboat can slide out smoothly when the blocking block is parallel to the shelf surface, preventing the lifeboat from being unable to slide out if the blocking block is not parallel to the shelf surface.

[0029] In summary, the present invention has the advantages of preventing rust on lifeboats that have been stored for a long time, facilitating the handling of rust spots, and protecting the lower surface of the rack from collision with the ground when placing lifeboats.

[0045] like Figures 1-4As shown, an embodiment of the present invention provides a lifeboat rack, including a rack 1. A movable frame 2 is slidably connected inside the rack 1. A connecting pipe 3 is inserted inside the movable frame 2. A material box 4 is inserted into the upper surface of the movable frame 2. A discharge pump 5 is provided inside the material box 4. A hose 6 is inserted into one side of the discharge pump 5. A push rod 7 is inserted into one side of the movable frame 2. A placement box 8 is inserted into one side of the rack 1. A handle 9 is provided inside the placement box 8. A telescopic rod 10 is slidably connected inside the handle 9. A compression spring 11 is inserted inside the telescopic rod 10. A button 12 is inserted into one end of the compression spring 11. A roller 13 is inserted into one side of the telescopic rod 10. A lead screw motor 14 is inserted inside the rack 1. One end of 4 is connected to a lead screw 15. A friction block 16 is slidably connected inside the shelf 1. A slider 17 is inserted into the lower surface of the movable frame 2. A slide rail 18 is inserted into the inside of the shelf 1. There are two connecting pipes 3 in opposite directions. The lower end of the connecting pipe 3 can be connected to the hose 6. A hole is provided on one side of the movable frame 2 so that the lower part of the connecting pipe 3 can be inserted into the interior. A slide groove is provided inside the shelf 1 so that the lead screw motor 14 and the lead screw 15 can be placed and the friction block 16 can be moved inside. There are two friction blocks 16, which are located in the slots provided in the middle part of the shelf 1 and are in opposite directions. A threaded hole is provided on one side of the friction block 16 so that the lead screw 15 can drive the friction block 16 to move horizontally in the slide groove.

[0046] The rust inhibitor inside the material tank 4 can be drawn out via the discharge pump 5 and hose 6 and sprayed onto the surface of the lifeboat placed on the shelf 1 through the connecting pipe 3. It is worth noting that the rust inhibitor can be mixed with water inside the material tank 4 to prevent rust from forming on the lifeboat surface. This avoids the problem of rusting caused by prolonged disuse of the lifeboat, which is prone to rusting after prolonged immersion in water. Rust that is difficult to remove can shorten the lifespan of the lifeboat. It is also worth noting that the discharge pump 5 and hose 6 each have two connecting pipes 3 that can be connected to two other connecting pipes 3, which are activated by the button 12 and pressure... The spring 11 allows the telescopic rod 10 to extend and retract inside the handle 9, achieving an adjustable length for use and avoiding the inconvenience caused by the telescopic rod 10 being too short. Through the roller 13, after the rust inhibitor is sprayed onto the surface of the lifeboat by the connecting pipe 3, the length of the telescopic rod 10 can be adjusted to drive the roller 13 to be inserted into the hole on one side of the shelf 1 at an angle to evenly apply the rust inhibitor to the surface of the lifeboat, achieving the effect of easily and evenly applying the rust inhibitor to the surface of the lifeboat, avoiding the problem of some areas rusting due to the inability to evenly apply the rust inhibitor to the lifeboat.

[0047] The push rod 7 and slider 17 can be manually pushed to move the movable frame 2 horizontally on the surface of the slide rail 18. This allows the entire movable frame 2 to move horizontally within the shelf 1, enabling the connecting pipe 3 to evenly spray rust inhibitor onto the lifeboat. This avoids the problem of the connecting pipe 3 being unable to evenly spray rust inhibitor onto the lifeboat surface due to the lifeboat's excessive length. The lead screw motor 14 and lead screw 15 can drive the friction block 16 to repeatedly move horizontally within the slide groove inside the shelf 1. This allows for repeated friction to reduce rust when it appears on the lifeboat surface, preventing reduced lifeboat life due to unremovable rust. It is worth noting that the lifeboat surface is made of iron, making it highly susceptible to incomplete protection leading to rust in some areas. If rust appears, friction blocks 16 can be used to reduce it and increase the lifespan of the lifeboat. Through the handle 9, the staff can manually drive the roller 13 into the slot opened on one side of the shelf 1 at an angle. This allows the staff to easily push and pull the roller 13 repeatedly to apply the rust inhibitor evenly to the surface of the lifeboat. This avoids the problem of the staff being unable to move the roller 13, which would make it inconvenient to apply the rust inhibitor. It is worth noting that when the roller 13 is not in use, the handle 9, telescopic rod 10, and roller 13 can be placed in the storage box 8 on one side of the shelf 1 for storage. If it is necessary to support one side of the shelf 1, the roller 13 can be taken out or the existing baffle structure can be used to block it inside the storage box 8 to prevent it from falling out.

[0048] like Figure 5 and Figure 6As shown, in this embodiment, a partition 19 is inserted into the lower surface of the shelf 1, a return spring 20 is inserted into the lower surface of the partition 19, a support plate 21 is inserted into one end of the return spring 20, an airbag 22 is inserted into the inside of the support plate 21, an air pump 23 is inserted into the inside of the support plate 21, an air outlet pipe 24 is inserted into one end of the air pump 23, a plug 25 is inserted into one side of the airbag 22, a lifting frame 26 is inserted into one side of the shelf 1, a drive motor 27 is provided inside the lifting frame 26, a lifting screw 28 is inserted into one end of the drive motor 27, a lifting rod 29 is slidably connected inside the lifting frame 26, a protective pad 30 is inserted into the lower surface of the lifting rod 29, a drive slot is opened on one side of the shelf 1, and a driver 31 is inserted into the inside of the drive slot. This driver 31 is a TB6600 driver, a professional two-phase stepper motor driver, compatible with Arduino and other main controllers, and can realize functions such as forward and reverse motor control and rotation angle control. Although the controller boasts powerful processing capabilities, its own output current capacity is relatively weak. It requires an intermediate bridge to connect the motor and the main controller, while simultaneously providing sufficient power to the motor. Just as the human brain is fragile, it commands the muscles to move the entire body. The driver is like a muscle, a crucial component responsible for the movement of the entire system. The TB6600 stepper motor driver employs an H-bridge bipolar constant-phase current drive, directly powered by 9–42VDC. It offers 7 microstepping control levels (1, 2 / A, 2 / B, 4, 8, 16, 32) and 8 current control levels (0.5A, 1A, 1.5A, 2A, 2.5A, 2.8A, 3.0A, 3.5A), supporting a maximum current output of 4A. All signal terminals are equipped with high-speed opto-isolation to prevent signal interference and support both common cathode and common anode signal input methods. For safety, the driver supports offline hold function, allowing users to debug while the device is powered on. Built-in temperature and overcurrent protection allows it to adapt to more demanding working environments.

[0049] The return spring 20 and support plate 21 cushion and dampen the lifeboat when it is placed inside the shelf 1, achieving the effect of cushioning and damping the entire equipment when it comes into contact with the ground. This avoids the problem of excessive pressure on the ground when the lifeboat is placed due to its weight, which could cause severe wear on the lower surface of the equipment. It is worth noting that when the lifeboat is placed on the upper surface of the shelf 1, the slight displacement of the shelf 1 and friction with the ground, as well as the increased weight of the shelf 1 and contact with the ground, can easily cause severe wear on the lower surface of the shelf 1. The partition plate 19 protects the lower surface of the shelf 1 when it comes into contact with the support plate 21, achieving the effect of protecting the lower surface of the shelf 1. This prevents the shelf 1 from falling and coming into contact with the support plate 21 due to the increased weight when the lifeboat is placed. To address the issue of impacts on the lower surface, the airbag 22 can be inflated via the air pump 23 and the air outlet pipe 24. This provides a secondary cushioning effect when the entire equipment is lowered due to increased gravity during the placement of the lifeboat, as the shelf 1 and partition 19 cushion the descent. This avoids the problem of the partition 19 and support plate 21 colliding when the initial reset spring 20 fails to provide cushioning. The plug 25 can be manually removed to expel the air from the airbag 22. This allows the airbag 22 to be removed from the support plate 21 when it needs to be replaced, preventing the airbag 22 from being unable to be removed due to the inability to release the air. It is worth noting that the surface of the airbag 22 may wear down after repeated use, making it irreparable.

[0050] The lifting rod 29 can be raised or lowered inside the lifting frame 26 by the drive motor 27 and the lifting screw 28. This allows the lifting rod 29 to be lowered to support one side of the entire equipment when the lifeboat needs to be placed in the water, making it easier for the lifeboat to slide off the surface of the shelf 1. This avoids the problem of staff having to use a crane to lift the lifeboat and put it into the water. The protective pad 30 can protect the lower surface of the lifting rod 29, thus protecting the lower surface of the lifting rod 29 from damage caused by repeated use of the lifting rod 29 due to friction with the ground. It is worth noting that there are two lifting rods 29 located inside the lifting frame 26, which can evenly support the shelf 1.

[0051] like Figure 7 As shown, in this embodiment, a motor base 32 is inserted into one side of the shelf 1, a rotating motor 33 is inserted into the inside of the motor base 32, a rotating rod 34 is inserted into one end of the rotating motor 33, a blocking block 35 is slidably connected to the upper surface of the shelf 1, and a locking block 36 is inserted into one side of the blocking block 35.

[0052] By rotating the motor 33 and the rotating rod 34, the blocking block 35 can be slowly moved horizontally on the upper surface of the shelf 1. This achieves the effect of securing the bottom of the lifeboat inside the shelf 1 when it needs to be stored, and allowing the blocking block 35 to rotate to one side of the shelf 1 and fall into the slot on one side of the shelf 1 when it needs to be lowered into the water, making it easy for the lifeboat to slide out. This avoids the problems of lifeboats slipping off the shelf 1 and derailing due to various situations when stored inside the shelf 1, and also prevents the lifeboat from being easily slid out of the shelf 1. The locking block 36 allows the blocking block 35 to slide to one side of the upper surface of the shelf 1, allowing it to fall into the slot on the upper surface of the shelf 1. In some slots, the lifeboat can be easily slid out for use when the blocking block 35 is parallel to the surface of the shelf 1. This avoids the problem that the lifeboat cannot be slid out because the blocking block 35 is not parallel to the surface of the shelf 1. It is worth noting that when the blocking block 35 is moved, the locking block 36 moves to the upper surface of the slot so that it can automatically fall into the inside so that the blocking block 35 is parallel to the shelf 1. When it is necessary to return the blocking block 35 to its original position, the blocking block 35 can be manually removed from the slot and the rotating motor 33 can be started to return the blocking block 35 to its original position. If the inside of the slot is worn or blocked, causing the locking block 36 to be unable to fall into the inside, the blocking block 35 will rotate out of the shelf 1 with the rotating rod 34 and will not fall out or be lost.

[0053] All electrical components mentioned in this article are connected to the external TB6600 main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0054] When using a lifeboat rack, the following steps are included;

[0055] Step 1: Spray the rust inhibitor from inside the tank into the connecting pipe through the discharge pump and hose, and then spray the rust inhibitor onto the surface of the lifeboat to prevent rust.

[0056] Step 2: The staff manually pushes the moving frame to spray the rust inhibitor from the connecting pipe onto the surface of the lifeboat placed on the shelf, thereby spraying the rust inhibitor evenly.

[0057] Step 3: Adjust the length of the telescopic rod inside the handle by manually pressing the button to remove the roller and place it into the shelf at an angle. Repeatedly pull the roller in and out to apply rust inhibitor to the lifeboat.

[0058] Step 4: By starting the lead screw motor and the lead screw, the friction block is repeatedly rubbed against the surface of the lifeboat, thereby reducing rust when it appears on the lifeboat.

[0059] Step 5: By using a return spring and airbag, the shelf can be lowered twice with cushioning during the placement of the lifeboat, thereby reducing wear and tear caused by the impact between the shelf and the ground.

[0060] Step Six: Inflate the airbag using an air pump and air outlet pipe to provide a second buffer when the shelf contacts the support plate. Then, manually remove the plug to deflate the airbag, making it easy to remove for repair or replacement.

[0061] Step 7: By driving the motor to rotate the lifting screw, the lifting rod is lowered from inside the lifting frame to support one side of the shelf, making it easier for the lifeboat to slide out from the shelf surface. The protective pad can protect the bottom of the lifting rod when it is lowered and in contact with the ground.

[0062] The technical solution provided by this invention is as follows: Rust inhibitor inside the material box 4 can be drawn out via the discharge pump 5 and hose 6 and sprayed onto the surface of the lifeboat placed on the shelf 1 via the connecting pipe 3, achieving the effect of preventing rust on the lifeboat surface and avoiding the problem of rusting due to prolonged disuse. The telescopic rod 10 can be extended and retracted inside the handle 9 via the button 12 and compression spring 11, achieving the effect of adjustable telescopic rod 10 length for use and avoiding the problem of inconvenience caused by an excessively short telescopic rod 10. Through the roller 13, after the rust inhibitor is sprayed onto the lifeboat surface via the connecting pipe 3, the length of the telescopic rod 10 can be adjusted to drive the roller 13 to be inserted obliquely into the hole on one side of the shelf 1 to spray rust inhibitor onto the lifeboat surface. The rust inhibitor is applied evenly, ensuring that the surface of the lifeboat is evenly coated with the rust inhibitor, thus avoiding the problem of rust in some areas due to uneven application of the rust inhibitor. The push rod 7 and slider 17 can be manually pushed to move the moving frame 2 horizontally on the surface of the slide rail 18, allowing the entire moving frame 2 to move horizontally within the shelf 1, enabling the connecting pipe 3 to evenly spray the rust inhibitor onto the lifeboat. This avoids the problem of the connecting pipe 3 being unable to evenly spray the rust inhibitor onto the lifeboat surface due to the lifeboat being too long. The lead screw motor 14 and lead screw 15 can drive the friction block 16 to repeatedly move horizontally within the groove opened inside the shelf 1, allowing for repeated friction to reduce rust when it appears on the lifeboat surface. This design effectively avoids the problem of reduced lifeboat life due to inability to clean rust. The lever 9 allows staff to manually insert the roller 13 at an angle into a slot on one side of the shelf 1, enabling them to easily and repeatedly push and pull the roller 13 to evenly apply rust inhibitor to the lifeboat surface. This avoids the inconvenience of applying rust inhibitor due to staff being unable to move the roller 13. The return spring 20 and support plate 21 provide cushioning and shock absorption when the lifeboat is placed inside the shelf 1, ensuring the entire equipment is cushioned and absorbs shock when in contact with the ground. This prevents excessive pressure on the ground when the lifeboat is too heavy, which could damage the lower surface of the equipment. In the event of severe wear, the partition 19 protects the lower surface of the shelf 1 from impact when it comes into contact with the support plate 21, thus preventing damage to the lower surface of the shelf 1 during the descent of the lifeboat due to increased gravity. The air pump 23 and air outlet pipe 24 inflate the airbag 22, providing a secondary cushioning effect when the shelf 1 descends with the partition 19 to buffer the descent during the lifeboat placement. This prevents the partition 19 from impacting the support plate 21 when the initial return spring 20 fails to provide sufficient cushioning. The plug 25 can be manually removed to release the air from the airbag 22.This design achieves the effect of allowing the airbag 22 to be removed from the support plate 21 by pulling out the plug 25 when it needs to be replaced, thus releasing the air inside the airbag 22 and preventing it from being unable to be removed due to the air inside the airbag 22 not being able to be released. Through the drive motor 27 and the lifting screw 28, the lifting rod 29 can be raised or lowered inside the lifting frame 26. This allows the lifting rod 29 to be lowered when the lifeboat needs to be placed in the water, supporting one side of the entire equipment to facilitate the lifeboat sliding off the surface of the shelf 1, avoiding the need for personnel to use a crane to lift the lifeboat and place it in the water. The protective pad 30 protects the lower surface of the lifting rod 29, preventing friction between the lower surface of the lifting rod 29 and the ground caused by repeated use. To address the issue of damage, rotating the motor 33 and the rotating rod 34 allows the blocking block 35 to slowly slide horizontally across the upper surface of the shelf 1. This achieves the effect of securing the bottom of the lifeboat inside the shelf 1 when it needs to be stored, and allowing the lifeboat to be easily slid out when it needs to be lowered into the water. This avoids the problems of lifeboats slipping off the shelf 1 or being unable to slide out easily due to various situations that may occur while the lifeboat is stored inside the shelf 1. Furthermore, the locking block 36 allows the blocking block 35 to slide to one side of the upper surface of the shelf 1 and fall into the locking slot provided on the upper surface of the shelf 1. This ensures that the lifeboat can be easily slid out when the blocking block 35 is parallel to the surface of the shelf 1, preventing the lifeboat from being unable to slide out when the blocking block 35 is not parallel to the surface of the shelf 1.
