Description

Technical Field

[0001] This application relates to the technical field of ship equipment, and more particularly to a swimming pool canopy device for ships. Background Technology

[0002] To cope with the complex and ever-changing weather conditions at sea and ensure that outdoor swimming pools can be used normally under different climatic conditions, while creating a relatively comfortable environment for passengers, most large cruise ships now have outdoor swimming pools equipped with retractable canopy devices. This design concept aims to flexibly adjust the usage status of the pool area according to weather changes.

[0003] However, most current cruise ship canopy systems use a single, large-sized screen structure. While this design simplifies the overall structure to some extent, it introduces a series of serious drawbacks. In actual operation, the excessively large screen size can easily lead to problems such as screen jamming or even damage due to inaccurate operation, severely affecting the normal use and opening / closing efficiency of the canopy. The drawbacks of a single, large-sized screen become even more pronounced when dealing with severe weather at sea, especially strong winds. Strong and unpredictable winds at sea can cause the entire large screen to withstand enormous wind pressure. Due to its large area, the area affected by the wind is also correspondingly larger. This immense wind pressure exerts strong impact and tensile forces on the screen's installation structure, posing a severe test to the reliability of the canopy system.

[0004] In conclusion, existing large cruise ship open-air swimming pool canopy systems, due to their design using a single large-sized screen, have significant shortcomings in terms of ease of operation and reliability in the face of severe weather such as strong winds, making it difficult to meet the needs of modern large cruise ships for high-quality, safe, and reliable canopy systems. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a swimming pool canopy device for ships, which can solve the above-mentioned problems existing in the prior art.

[0006] To achieve the above objectives, this application adopts the following technical solution: A swimming pool canopy device for ships includes: Two fixed track units are arranged along a first direction. Each fixed track unit includes a first column and two fixed guide rails extending along a second direction perpendicular to the first direction. Each fixed guide rail is connected to a first column at both ends, and the fixed guide rail is supported at a certain height by the first column. Four canopy units are provided. Two canopy units are installed on each of the fixed track units. Each canopy unit includes a curtain and several support frames. The support frames span and slide across two of the fixed guide rails in a first direction. The curtain is connected to each of the support frames. The curtain is opened or closed by sliding the support frames relative to the fixed guide rails.

[0007] Optionally, the two ends of the support frame are connected to pulleys that cooperate with the fixed guide rail, and the support frame is slidably connected to the fixed guide rail through the pulleys.

[0008] Optionally, it also includes a traction unit, which is connected to the support frame and drives the support frame to move to unfold or retract the curtain.

[0009] Optionally, in the retracted state of the canopy unit, the two canopy units on each fixed track unit are respectively retracted to the two ends of the fixed guide rail.

[0010] Optionally, it also includes a lifting rail unit. Along the second direction, each of the fixed rail units has a lifting rail unit at both ends. Each lifting rail unit includes a second column and two lifting rails corresponding to the fixed rails. The lifting rails are liftably installed on the second column. When the lifting guide rail is raised to align with the fixed guide rail, the canopy unit can slide along the lifting guide rail and the fixed guide rail to unfold or retract; when the canopy unit is fully retracted into the lifting guide rail, the lifting guide rail can drive the canopy unit to descend to near the ground.

[0011] Optionally, it also includes a lifting drive device, which is connected to the lifting guide rail to drive the lifting guide rail to move up and down along the second column.

[0012] Optionally, the lifting drive device includes a motor, a first gear, a second gear, and a chain. The first gear is connected to the motor, the second gear is rotatably mounted on the top of the second column, and the chain is sleeved on the first gear and the second gear. The lifting guide rail is connected to the chain, and the chain is driven by the motor to move, thereby driving the lifting guide rail to rise and fall.

[0013] Optionally, the lifting drive device further includes a guide rail bracket extending along the first direction. The guide rail bracket spans and supports four lifting guide rails of two lifting track units located on the same side. The chain is located between the two lifting track units and connected to the guide rail bracket. The chain drives the guide rail bracket to lift and lower, thereby driving the four lifting guide rails on the same side to lift and lower.

[0014] Optionally, the lifting drive device further includes a gear bracket, which is installed between the two adjacent second columns of the two lifting guide rail units, and the second gear is rotatably mounted on the gear bracket.

[0015] Optionally, the lifting drive device further includes a transition bracket and a sliding sleeve, wherein the first column and the second column are respectively equipped with the sliding sleeve, and the transition bracket connects each of the sliding sleeves and the guide rail bracket.

[0016] The beneficial effects of this application are as follows: This application divides the canopy into four independent canopy units, significantly reducing the size and weight of each unit. Due to the smaller size of the canopy units, their position and movement distance are easier to control precisely during sliding, effectively avoiding problems such as screen jamming and wrinkling caused by inaccurate operation. This improves the efficiency of opening and closing the canopy, ensuring smooth unfolding and retraction. Furthermore, this application's canopy device breaks down a single large screen into multiple smaller units, significantly reducing the wind pressure area borne by each unit, thereby lowering the overall wind pressure. This allows the canopy device to operate more stably and reliably in strong winds, reducing safety hazards such as screen loosening, deformation, or even detachment caused by excessive wind pressure. When a canopy unit is damaged in severe weather, due to its independent structural design, only the damaged unit needs to be repaired or replaced, unlike traditional canopy devices that require operation of the entire large screen. This not only reduces maintenance costs but also shortens repair time, improving the availability and reliability of the canopy device. Attached Figure Description

[0020] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0023] To cope with the complex and ever-changing weather conditions at sea and ensure that outdoor swimming pools can be used normally under different climatic conditions, while creating a relatively comfortable environment for passengers, most large cruise ships now have outdoor swimming pools equipped with retractable canopy devices. This design concept aims to flexibly adjust the usage status of the pool area according to weather changes.

[0024] However, most current cruise ship canopy systems use a single, large-sized screen structure. While this design simplifies the overall structure to some extent, it introduces a series of serious drawbacks. In actual operation, the excessively large screen size can easily lead to problems such as screen jamming or even damage due to inaccurate operation, severely affecting the normal use and opening / closing efficiency of the canopy. The drawbacks of a single, large-sized screen become even more pronounced when dealing with severe weather at sea, especially strong winds. Strong and unpredictable winds at sea can cause the entire large screen to withstand enormous wind pressure. Due to its large area, the area affected by the wind is also correspondingly larger. This immense wind pressure exerts strong impact and tensile forces on the screen's installation structure, posing a severe test to the reliability of the canopy system.

[0025] In conclusion, existing large cruise ship open-air swimming pool canopy systems, due to their design using a single large-sized screen, have significant shortcomings in terms of ease of operation and reliability in the face of severe weather such as strong winds, making it difficult to meet the needs of modern large cruise ships for high-quality, safe, and reliable canopy systems.

[0026] To overcome the above technical problems, such as Figures 1-3 As shown in the figure, this application provides a swimming pool canopy device for ships, including: Two fixed track units 2 are arranged along a first direction. Each fixed track unit 2 includes a first column 22 and two fixed guide rails 21 extending along a second direction perpendicular to the first direction. Each fixed guide rail 21 is connected to a first column 22 at both ends, and the fixed guide rail 21 is supported at a certain height by the first column 22. Four canopy units 1, two of the canopy units 1 are installed on each of the fixed track units 2, each of the canopy units 1 includes a curtain and several support frames, the support frames span across and slide along two of the fixed guide rails 21 in a first direction, the curtain is connected to each of the support frames, and the curtain is opened or closed by the sliding of the support frames relative to the fixed guide rails 21.

[0027] Specifically, when the canopy needs to be unfolded, the support frame is moved along the fixed guide rail 21 in the first direction by a drive device (which can be electric or manual). Since the canopy is connected to each support frame, the movement of the support frame will cause the canopy to gradually unfold, thereby covering the space above the pool and providing shade and rain protection. Conversely, when the canopy needs to be retracted, the support frame is driven to slide in the opposite direction, and the canopy is retracted, opening up the space above the pool.

[0028] Compared to traditional single-piece large-scale canopy devices, this application divides the canopy into four independent canopy units 1. The size and weight of each canopy unit 1 are significantly reduced. Due to the smaller size of the canopy unit 1, its position and movement distance are easier to control precisely during sliding, effectively avoiding problems such as screen jamming and wrinkling caused by inaccurate operation. This improves the efficiency of opening and closing the canopy and ensures that the canopy can be smoothly unfolded and retracted. In addition, the canopy device of this application divides a single large-scale screen into multiple small-sized canopy units 1. The wind pressure area borne by each canopy unit 1 is significantly reduced, thereby reducing the overall wind pressure. This allows the canopy device to operate more stably and reliably in strong winds, reducing safety hazards such as screen loosening, deformation, or even falling off due to excessive wind pressure. When a certain cyclorama unit 1 is damaged in severe weather, due to its independent structural design, only the damaged cyclorama unit 1 needs to be repaired or replaced, instead of operating the entire large-size cyclorama as in traditional cyclorama devices. This not only reduces maintenance costs but also shortens repair time and improves the availability and reliability of the cyclorama device.

[0029] In one embodiment, the two ends of the support frame are connected to pulleys that cooperate with the fixed guide rail 21, and the support frame is slidably connected to the fixed guide rail 21 through the pulleys.

[0030] In this embodiment, the support frame is a key support component of the canopy unit 1. It is equipped with pulleys at both ends, and the fixed guide rail 21 provides a sliding track for the pulleys. The two cooperate with each other to form a slidable connection between the support frame and the fixed guide rail 21. This structure allows the support frame to move smoothly along the fixed guide rail 21, thereby driving the curtain connected to the support frame to open or close.

[0031] Compared to traditional sliding connections, rolling friction makes the sliding of the support frame on the fixed guide rail 21 easier and smoother, reducing jamming and stalling caused by excessive friction, and ensuring the stability of the canopy's opening and closing process. Because rolling friction has lower frictional force, wear between the support frame and the fixed guide rail 21 is also reduced. Over long-term use, this low-wear characteristic effectively extends the service life of both the support frame and the fixed guide rail 21, reducing equipment maintenance costs and replacement frequency. Lower frictional resistance reduces the driving force required to move the support frame, thereby reducing the power requirements of the drive unit.

[0032] In one embodiment, the system further includes a traction unit connected to the support frame, which drives the support frame to move in order to unfold or retract the curtain.

[0033] In this embodiment, the introduction of the traction unit enables the automated operation of the canopy device. Operators can easily unfold and retract the canopy by controlling the start, stop and direction of movement of the traction unit, without having to manually push or pull the heavy support frame. This greatly improves the convenience and efficiency of operation, and is especially suitable for the needs of frequent canopy adjustments on large cruise ships.

[0034] The following example illustrates how to configure the traction unit: Electric winch mechanism: mainly composed of electric motor, drum, reducer, brake and other components. The electric motor provides power, the reducer reduces the speed and increases the torque, and then drives the drum to rotate. The wire rope is wound on the drum, and the support frame is moved by winding and unwinding the wire rope.

[0035] Electric linear actuator mechanism: mainly composed of drive motor 41, reduction gear, screw, nut, guide sleeve, push rod, slide, spring, housing, turbine, micro-control switch, etc.

[0036] Hydraulic cylinder mechanism: mainly composed of cylinder barrel, cylinder head, piston, piston rod, sealing device, etc. Pressure oil is supplied by the hydraulic system, which pushes the piston to make linear reciprocating motion within the cylinder barrel, thereby moving the piston rod and achieving traction of the support frame.

[0037] In one embodiment, reference is made to Figure 4 When the canopy unit 1 is in the retracted state, the two canopy units 1 on each fixed track unit 2 are respectively retracted to the two ends of the fixed guide rail 21.

[0038] When the tarpaulin is retracted, the traction unit applies force to the support frame, causing it to slide along the fixed guide rail 21. Designed to retract at both ends of the fixed guide rail 21, the support frame gradually retracts the tarpaulin during sliding, converging it towards both ends of the fixed guide rail 21. This design cleverly utilizes the length of the fixed guide rail 21, placing the two tarpaulin units 1 at opposite ends, avoiding interference and overlap between the units during retraction, and providing a neat space for tarpaulin storage. When the tarpaulin units 1 are retracted to both ends of the fixed guide rail 21, staff can more easily conduct a comprehensive inspection. Because the tarpaulin units 1 are in a relatively dispersed and orderly position, there is no need to search and operate in a complex environment, allowing for quick location of components requiring maintenance, such as damaged areas of the tarpaulin or loose parts of the support frame, greatly improving maintenance efficiency.

[0039] Ships sailing at sea occasionally face rough sea conditions, and traditional canopy devices, even when retracted, are still in a high position and remain at risk of being damaged by huge waves.

[0040] To overcome this problem, in one embodiment, [the following is combined] Figure 4and Figure 5 It also includes a lifting track unit 3. Along the second direction, each fixed track unit 2 has a lifting track unit 3 at both ends. Each lifting track unit 3 includes a second column 32 and two lifting guide rails 31 corresponding to the fixed guide rail 21. The lifting guide rails 31 are installed on the second column 32 in a lifting manner. When the lifting guide rail 31 is raised to align with the fixed guide rail 21, the canopy unit 1 can slide along the lifting guide rail 31 and the fixed guide rail 21 to expand or retract; when the canopy unit 1 is completely retracted to the lifting guide rail 31, the lifting guide rail 31 can drive the canopy unit 1 to descend to near the ground.

[0041] In practical use, when the canopy needs to be unfolded or retracted, the lifting guide rail 31 rises to a position aligned with the fixed guide rail 21. At this time, the support frame of the canopy unit 1 can smoothly slide on the lifting guide rail 31 and the fixed guide rail 21 via pulleys. The traction unit provides power to drive the support frame to move, thereby realizing the unfolding or retraction of the canopy, providing functions such as sunshade and rain protection for the swimming pool. When the ship faces severe sea conditions, in order to avoid the canopy device being damaged by huge waves, the canopy unit 1 is first completely retracted onto the lifting guide rail 31. Then, the lifting guide rail 31 is lowered along the second column 32, bringing the retracted canopy unit 1 down to a position close to the ground. In this way, the overall height of the canopy device is reduced, greatly reducing the range and intensity of the impact of wind and waves, and reducing the risk of damage. After the severe sea conditions have passed, the lifting guide rail 31 is raised again to align with the fixed guide rail 21, restoring the normal function of the canopy device.

[0042] Therefore, in this embodiment, the canopy unit 1 can be lowered to near the ground along the lifting guide rail 31, significantly reducing the overall height, decreasing the contact area and impact force with wind and waves, effectively protecting the various components of the canopy device, such as the curtain and support frame, extending the service life of the device, and reducing maintenance costs. During maritime navigation, severe sea conditions are unavoidable. This structure allows the canopy device to enter a "low-profile" protection state in harsh environments, ensuring normal operation even after the storm has passed, improving the reliability and stability of the equipment, and providing more durable protection for use in shipboard swimming pools.

[0043] In one embodiment, combined with Figure 2 It also includes a lifting drive device 4, which is connected to the lifting guide rail 31 to drive the lifting guide rail 31 to move up and down along the second column 32.

[0044] In this embodiment, the introduction of the lifting drive device 4 automates the lifting process of the canopy device. Operators no longer need to manually and laboriously adjust the height of the lifting guide rail 31; they only need to issue commands via a control panel or remote control, and the lifting drive device 4 can precisely control the lifting speed and position of the lifting guide rail 31 according to a preset program, greatly improving operational convenience and efficiency. In the event of sudden severe sea conditions, the automated control system can respond quickly and promptly activate the lifting drive device 4, allowing the canopy device to descend rapidly to a safe position, effectively reducing the risk of damage to the canopy device due to delays caused by manual operation.

[0045] In one embodiment, the lifting drive device includes a motor 41, a first gear 42, a second gear 43, and a chain 44. The first gear 42 is connected to the motor 41, the second gear 43 is rotatably mounted on the top of the second column 32, and the chain 44 is sleeved on the first gear 42 and the second gear 43. The lifting guide rail 31 is connected to the chain 44, and the chain 44 is driven by the motor 41 to drive the lifting guide rail 31 to rise and fall.

[0046] The working principle of this lifting drive device is based on the gear-chain transmission mechanism. When the motor 41 starts, its output shaft begins to rotate, driving the first gear 42 connected to it to rotate synchronously. Since the chain 44 is tightly fitted onto the first gear 42 and the second gear 43, the rotation of the first gear 42 will drive the chain 44 to start running. During the operation of the chain 44, it will drive the second gear 43 to rotate at the top of the second column 32. At the same time, because the lifting guide rail 31 is fixedly connected to the chain 44, the movement of the chain 44 will directly pull the lifting guide rail 31 to make a linear lifting motion along the second column 32.

[0047] Specifically, for example, when motor 41 rotates forward, the first gear 42 rotates clockwise, driving the second gear 43 to rotate clockwise via chain 44. Simultaneously, chain 44 pulls the lifting guide rail 31 downwards, causing it to descend. Conversely, when motor 41 rotates in reverse, the first gear 42 rotates counter-clockwise, driving the second gear 43 to rotate counter-clockwise, and chain 44 lifts the lifting guide rail 31 upwards. By controlling the forward and reverse rotation of motor 41 and its operating time, the lifting height and speed of the lifting guide rail 31 can be precisely controlled, thereby enabling flexible adjustment of the position of the canopy unit 1.

[0048] In this embodiment, the gear-chain 44 transmission is a highly efficient transmission method. Compared to some friction transmission methods, it has less energy loss during power transmission. The power output from the motor 41 can be directly transmitted to the lifting guide rail 31 through the gears and chain 44, allowing more energy to be used for lifting and lowering movements, thus improving the overall energy efficiency of the system and reducing energy consumption. Due to its high transmission efficiency, the motor 41 can quickly transmit power to the lifting guide rail 31 after starting, enabling the lifting guide rail 31 to respond quickly to lifting and lowering. In the event of an emergency descent of the canopy device in severe sea conditions, the operation can be completed quickly, effectively protecting the canopy device from damage by wind and waves. The gear and chain 44 transmission method has high reliability and stability. The gear tooth design ensures an accurate transmission ratio, and the strength and flexibility of the chain 44 allow it to withstand large loads and remain stable during movement.

[0049] In one embodiment, reference is made to Figure 2 The lifting drive device further includes a guide rail bracket 45 extending along the first direction. The guide rail bracket 45 spans and supports four lifting guide rails 31 of two lifting track units 3 located on the same side. The chain 44 is located between the two lifting track units 3 and connected to the guide rail bracket 45. The chain 44 drives the guide rail bracket 45 to lift and lower, thereby driving the four lifting guide rails 31 on the same side to lift and lower.

[0050] After the motor 41 starts, its output shaft drives the first gear 42 to rotate, which in turn drives the chain 44 to run. During the operation of the chain 44, because it is connected to the guide rail bracket 45, it will pull the guide rail bracket 45 to move up and down in a straight line along the second column 32. The guide rail bracket 45 supports four lifting guide rails 31 on the same side. When the guide rail bracket 45 rises and falls, it will drive the four lifting guide rails 31 to rise or fall synchronously.

[0051] The guide rail bracket 45 spans and supports four lifting guide rails 31 on the same side, connecting the originally relatively independent lifting guide rails 31 into a whole, which greatly enhances the rigidity of the entire lifting structure. During the ship's navigation, it will be affected by factors such as wind and waves, resulting in swaying and vibration. This integrated structure can effectively resist these external forces, reduce the swaying and deformation of the lifting guide rails 31, ensure the stability of the canopy unit 1 during the lifting process, and reduce the risk of damage to the canopy unit 1 due to structural instability.

[0052] The four lifting rails 31 on the same side are raised and lowered synchronously via the rail bracket 45, ensuring that the height of both sides of the canopy unit 1 remains consistent during expansion and contraction. This avoids problems such as wrinkles and tilting of the canopy due to asynchronous lifting on both sides, ensuring the flatness and aesthetics of the canopy and improving its usability. Furthermore, the synchronous lifting of the four lifting rails 31 via the rail bracket 45 simplifies the design of the control system. Only one action of the motor 41 is needed to achieve synchronous movement of all lifting rails 31 on the same side, eliminating the need for independent control of each rail. This reduces the complexity and cost of control, and improves the reliability and stability of the system.

[0053] In one embodiment, the lifting drive device further includes a gear bracket 48, which is installed between the two adjacent second columns 32 of the two lifting guide rail 31 units, and the second gear 43 is rotatably installed on the gear bracket 48.

[0054] The gear bracket 48 securely mounts the second gear 43 between the adjacent second columns 32 of the two lifting guide rail units 31, providing a stable support platform for the second gear 43. Precise mounting of the second gear 43 via the gear bracket 48 ensures the meshing accuracy between the second gear 43, the first gear 42, and the chain 44. Good meshing reduces impact and noise during transmission, improving the smoothness and efficiency of the transmission.

[0055] In one embodiment, reference is made to Figure 4 and Figure 5 The lifting drive device further includes a transition bracket 47 and a sliding sleeve 46. The first column 22 and the second column 32 are respectively equipped with the sliding sleeve 46, and the transition bracket 47 connects each of the sliding sleeves 46 and the guide rail bracket 45.

[0056] Specifically, the chain 44 pulls the guide rail bracket 45 to move linearly up and down along the second column 32. Since the guide rail bracket 45 is connected to the adapter bracket 47, the movement of the guide rail bracket 45 will drive the adapter bracket 47 to move together. The adapter bracket 47 is connected to the first column 22 and the second column 32 respectively through the sliding sleeve 46. During the movement, the sliding sleeve 46 slides on the column, providing precise guidance for the movement of the adapter bracket 47 and the guide rail bracket 45, ensuring that they can only move linearly along the axis of the column and will not deviate or shake.

[0057] Specifically, when the motor 41 rotates forward and lowers the guide rail bracket 45, the adapter bracket 47 also moves downward under the drive of the guide rail bracket 45. At the same time, the sliding sleeve 46 slides downward along the first column 22 and the second column 32 to ensure the smoothness and straightness of the entire movement process. When the motor 41 rotates in reverse and raises the guide rail bracket 45, the adapter bracket 47 and the sliding sleeve 46 move upward accordingly to realize the raising operation of the skylight device.

[0058] In this embodiment, the sliding sleeve 46 on the first column 22 and the second column 32 provides precise guidance for the movement of the adapter bracket 47 and the guide rail bracket 45. During ship navigation, factors such as wind and waves can cause swaying and vibration. The sliding sleeve 46 ensures that the guide rail bracket 45 and the adapter bracket 47 always move in a straight line along the axis of the column, avoiding problems such as movement deviation, swaying, or jamming caused by external interference, making the raising and lowering process of the canopy device more stable and smooth. The sliding sleeve 46 is usually made of wear-resistant material, with a low coefficient of friction with the column. During movement, the sliding sleeve 46 can reduce the direct friction between the adapter bracket 47 and the column, reduce wear, and extend the service life of the components. At the same time, the lower friction also helps to improve the sensitivity and efficiency of movement, allowing the motor 41 to drive the raising and lowering of the canopy device more easily.
