Description

Technical Field

[0001] The utility model belongs to the field of boat storage and launching, and in particular relates to a sideboard storage and launching device in a boat cabin. Background Art

[0002] As an important means of water transportation, boats play an irreplaceable role in the fields of ocean exploration, fishing operations, water leisure and entertainment. With the advancement of science and technology and the diversification of application needs, various equipment and systems on boats are also constantly evolving to improve their functionality and safety. Boat launching and retrieving refers to the launch and recovery of materials, equipment or personnel on the water surface without docking. This process not only requires a high degree of operational flexibility, but also must ensure the safety of the entire operation to avoid damage to the hull, while taking into account the impact of sea conditions. As a key equipment on the boat, the launching and retrieving device is crucial to achieving specific tasks (such as deploying lifeboats, diving equipment, scientific research instruments, etc.). The device allows users to safely and efficiently launch items or equipment from the boat into the water, or recover them from the water to the boat during navigation.

[0003] Traditional side-lifting and retracting usually rely on manual or semi-automatic mechanical devices, which are often fixed at specific positions on the hull. The lifting and lowering of items are completed through winches, pulley systems or hydraulic drives. The exposed structure means that the boat and its retracting and retracting mechanism are directly exposed to the outside of the hull. This not only affects the overall stealth performance of the boat, making it easy for the boat to be detected by the enemy, but also makes the device vulnerable to wave impact and corrosion in severe sea conditions, reducing its service life and reliability. When operating in high sea conditions, existing devices often find it difficult to keep the boat stable, and the boat sways violently during the retracting and retracting process, which can easily cause damage to the boat or injury to the operator. The lack of effective wave compensation and tension control mechanisms makes the retracting and retracting operation risky. Due to the simple structure, traditional devices often rely on manual operation or low automation, resulting in slow retracting and retracting speed of the boat, untimely response, and difficulty in meeting the needs of rapid deployment in emergency situations. Many device designs do not fully consider the optimal use of deck space. The huge structure occupies precious deck area, limiting the expansion and implementation of other functions of the boat.

DETAILED DESCRIPTION

[0032] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0033] Implementation example:

[0034] like Figure 1-2As shown, a device for storing and releasing the side of a boat in a cabin comprises a boat lifting structure 100 for releasing and storing the boat, a translation structure 200 for moving the boat, a bracket structure 300 for placing and supporting the boat, and a hydraulic control system 400 for synchronously coordinating the operation of the lifting and releasing device and providing hydraulic power. The lifting and releasing device of the utility model is arranged in the cabin, and the lifting and releasing structure is moved to the side of the boat by the translation structure 200, so as to realize the storage of the boat in the cabin and the lifting and releasing of the side of the boat.

[0035] The translation structure 200 is welded to the ship deck through a welding base, and the translation rail 210 is connected to the welding base through bolts. The translation rail 210 is divided into two groups and symmetrically arranged on both sides of the davit structure 100. The fixed rail 213 is a groove structure, and the two ends of the groove structure are sealed with plates to form a mechanical limit to limit the extreme position of the movement of the mobile base 220 on the translation rail 210. The inner sides of the left and right fixed rails 213 are relatively concave to form a slide groove, and the outer sides are parallelly provided with a screw rod 211 and a guide rod 212. The two sides of the movable base 220 are knotted on the screw rod 211 and the guide rod 212. In this embodiment, the translation drive device 230 is a screw motor, which is installed at the tail end of the fixed rail 213, converts hydraulic energy into mechanical energy and transmits it to the screw rod 211. Both ends of the screw rod 211 are fixed and can only rotate but not move forward and backward. The rotation of the screw rod 211 drives the movable base 220 to move forward and backward. At the same time, the rollers 221 arranged on both sides of the lower part of the movable base 220 roll in the slide groove. The setting of the guide rod 212 and the roller 221 makes the movable base 220 drive the movement of the davit structure 100 more stable and smooth.

[0036] The mobile base 220 is provided with a davit base 110 and a luffing cylinder rotating support. The davit base 110 is used to install a jib 120 around which the davit can rotate. The luffing cylinder rotating support is used to install a rotation drive device 130. In this embodiment, the rotation drive device 130 is a luffing cylinder, and the cylinder body of the luffing cylinder is rotatably connected to the luffing cylinder rotating support. The davit 120 is the main force-bearing component of the retracting and releasing device. The luffing cylinder rotating support is provided on the davit 120, which is used to install the piston rod of the luffing cylinder. Under the push of the piston rod of the luffing cylinder, the davit 120 can be poured in and out around the davit base 110. In addition, a hydraulic winch 170 is also provided on the davit 120. The sling of the hydraulic winch 170 passes through the corner pulley 140, the head pulley 150, the anti-sway cylinder 160 in sequence, and finally connects to the boat to be retracted.

[0037] The corner pulley 140 is connected to the boom 120 through the third oil cylinder 141. The cylinder body of the third oil cylinder 141 is fixed on the boom 120. The corner pulley 140 is connected to the piston rod of the third oil cylinder 141. The extension and retraction of the piston rod realizes the buffering of the sling on the corner pulley 140. At the same time, the third oil cylinder 141 is connected to the accumulator 142. The accumulator 142 is an airbag accumulator filled with nitrogen. The hydraulic oil in the third oil cylinder 141 enters the accumulator 142 and squeezes the inert gas to achieve a buffering effect, reduce the impact force on the sling, extend the service life of the sling, reduce the impact on the boat, and maintain the stability of the process of folding and releasing the boat.

[0038] like Figure 3 As shown, the head pulley 150 is connected to the boom 120 via a first rotating shaft (not shown in the figure), the cylinder body of the first oil cylinder 151 is fixed on the boom 120, the piston rod is connected to the head pulley 150, and the extension and contraction of the piston rod drives the head pulley 150 to swing around the first rotating shaft, and the swing amplitude is determined by the extension and contraction degree of the first oil cylinder 151. The anti-sway cylinder 160 is connected to the head pulley 150 via a second rotating shaft (not shown in the figure), the cylinder body of the second oil cylinder 161 is fixed on the boom 120, and the piston rod is connected to the anti-sway cylinder 160, and the extension and contraction of the piston rod drives the anti-sway cylinder 160 to swing around the second rotating shaft, and the swing amplitude is determined by the extension and contraction degree of the second oil cylinder 161. The extension and retraction directions of the first oil cylinder 151 and the second oil cylinder 161 are perpendicular to each other, limiting the swing of the sling in four degrees of freedom: front, back, left, and right. No matter how much the boat shakes, the wire rope will not jump out of the pulley, thus preventing the occurrence of wheel-off accidents, ensuring the personal safety of the passengers, and reducing the shaking of the boat during the folding and releasing process.

[0039] In this embodiment, the hydraulic winch 170 is a wave compensation hydraulic winch, which is divided into normal lifting and lowering conditions and wave compensation conditions. The lifting and lowering conditions realize the retraction and release of the sling by the forward and reverse rotation of the winch, thereby realizing the retraction and release of the boat. The wave compensation condition is the constant tension condition of the sling. When the waves surge, the boat is lifted by the waves, the sling is loose, the force on the winch is less than the set wave compensation tension, and the hydraulic oil pushes the winch to rotate forward to tighten the sling; when the waves sink, the boat leaves the water surface, and all the weight acts on the winch. The force on the winch is greater than the set wave compensation tension, the hydraulic oil overflows, and the winch reverses under the action of the boat's own weight to lower the boat. Under the constant tension condition, the sling always tightens the boat with a constant tension, maintaining the stability of the boat on the water surface, facilitating operations such as unhooking, and also reducing the risk of collision between the boat and other equipment.

[0040] The bracket structure 300 is composed of two groups of brackets arranged on both sides of the translation track 210. The bracket structure 300 includes a bottom bracket 320 and a side bracket 310, which are vertically arranged on the deck. The side bracket 310 is arranged parallel to the fixed track 213. The bottom bracket 320 provides support for the bottom of the ship at the lowest part, and the side brackets 310 are arranged in groups of two at a certain angle and tilted upward to match the lower angle of the boat to be stored and provide support for the lower side of the boat. At the same time, the boat in the storage state can be fixed by tying ropes to prevent the boat from shaking and colliding when the ship is sailing, and at the same time, the slings are unloaded to extend the service life of the slings.

[0041] The retraction and extension of the utility model are driven and controlled by the hydraulic control system 400. The power source of the hydraulic control system 400 is a hydraulic pump, which is driven by an electric motor. The hydraulic pump delivers hydraulic oil with a certain pressure and flow rate to each control valve. By manipulating the direction and opening size of the control valve, the movement direction and speed of the hydraulic actuator can be controlled, ultimately realizing the functions of lifting and lowering the boat, the boom driving the boat to be poured in and out, the mobile base driving the boom and then driving the boat to move forward and backward, anti-swaying, constant tension wave compensation, sling buffering and the like.

[0042] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
