Description

Technical Field

[0001] The present invention relates to the technical field of underwater elevators, and particularly to an underwater adventure tour submarine Ferris wheel elevator structure. Background Art

[0002] A submarine elevator is a special elevator system, and its technical principle is mainly based on the basic working principle of an elevator. However, in order to adapt to the deep-sea environment, special design and improvement are required. Specifically, a submarine elevator usually consists of multiple parts such as an elevator car, a track system, a power system, a control system, and a safety protection system. The elevator car is used to carry passengers, and the track system ensures that the elevator can move up and down along a predetermined path. The power system provides the energy required for the elevator to operate, and the control system is responsible for starting, stopping, speed regulation, and switching of the running direction of the elevator. The safety protection system is used to monitor the running state of the elevator and take timely measures in case of abnormal situations to ensure the safety of passengers.

[0003] Within the framework of the prior art, as a means of transportation connecting the sea level and the seabed, the passage length of a submarine elevator is generally long, which directly leads to a significant energy consumption for a single trip. In addition, the elevator needs to overcome a strong buoyancy force during operation, further increasing the load pressure on the track structure. More critically, the people inside the elevator need to breathe continuously in a confined space, which leads to a significant increase in the consumption of life-sustaining substances such as oxygen inside the elevator, thus posing higher requirements for the life support system of the elevator. These factors together constitute important challenges in the design and operation of submarine elevators. Summary of the Invention

An air port communicating inside and outside is provided at the bottom of the elevator shaft located inside the sightseeing cabin. A sliding seal assembly is provided between the moving platform and the inner wall of the elevator shaft. A lifting mechanism is arranged at the lower end of the moving platform.

[0006] Preferably, the elevator car is connected with an electrolytic hydrogen production device and a hydrogen storage device. The electrolytic hydrogen production device includes a water inlet, an oxygen outlet, and a hydrogen outlet. The oxygen outlet communicates with the inside of the elevator car, and the hydrogen outlet communicates with the hydrogen storage device. The water inlet communicates outward with the inside of the elevator shaft. The hydrogen storage device includes a fuel cell, and the hydrogen outlet is connected to the fuel cell.

[0007] Preferably, a seawater desalination filter is provided at the water inlet, and both the electrolytic hydrogen production device and the hydrogen storage device are arranged at the upper part of the elevator car.

[0008] Preferably, the outer surface of the elevator car is provided with no less than two guiding devices, which are evenly distributed along the outer surface of the elevator car. A guiding groove is provided on the inner surface of the elevator shaft, and the guiding groove is straight and distributed from top to bottom along the inside of the elevator shaft.

[0009] Preferably, the guiding device includes a pulley, and the pulley is embedded inside the guiding groove. The number of guiding devices in the vertical direction on the same plane is not less than two.

[0010] Preferably, the mobile platform can descend into the tour cabin below the elevator shaft; the upper surface area of the mobile platform is smaller than the lower surface, a water trough is formed along the perimeter of the upper end of the mobile platform, and the water pumping structure is arranged at the water trough; a hydraulic lifting mechanism is arranged below the mobile platform, and a liquid level sensor is arranged in the water trough along the edge of the mobile platform; the mobile platform is in sealed contact with the inner wall of the elevator shaft.

[0011] Preferably, a gas check valve is arranged at the bottom of the elevator car, and the gas check valve allows the gas in the elevator car to be discharged from the elevator car.

[0016] Preferably, a locking structure is arranged on the inner wall of the elevator shaft at the position where the elevator car needs to stop stably, the locking structure includes an electromagnet, and a fixing plate made of a magnetizable material is arranged on the outer surface of the elevator car.

[0017] (III) Beneficial effects: Compared with the prior art, the present invention provides an underwater adventure and sightseeing submarine Ferris wheel elevator structure, which has the following beneficial effects: 1. For the underwater adventure and sightseeing submarine Ferris wheel elevator structure, through the water pumping structure and the water discharging structure, in cooperation with the lifting of the elevator, when the elevator ascends, the water discharging structure is activated, and by using the water valve, the seawater inside the ocean enters between the elevator shaft and the elevator car, enabling the elevator car to obtain an upward buoyancy force, effectively sharing the pulling force that the traction machine needs to bear, thus significantly reducing the operating power of the traction machine, achieving efficient utilization of energy, and further enhancing the stability and safety during the elevator's ascent; when the elevator descends, the water discharging structure is closed, and the water pumping structure is opened to pump out the seawater between the elevator shaft and the elevator car and discharge it back into the ocean. As the water level drops, the volume of water displaced by the elevator car becomes smaller, and the upward buoyancy force it receives becomes smaller, so it is easier to descend; moreover, the support of the seawater plays a buffering role during the descent of the elevator car, effectively slowing down the downward acceleration of the elevator car and avoiding potential safety hazards that may be caused by excessive speed, bringing a more stable and comfortable riding experience for tourists; the design of the lower moving platform also ensures that seawater does not enter the interior of the sightseeing cabin, and while supporting the elevator shaft, it plays a sealing role, ensuring the stability and safety of the overall elevator operating system.

[0018] 2. For the underwater adventure and sightseeing submarine Ferris wheel elevator structure, by arranging an electrolytic hydrogen production device inside the elevator car, when the elevator ascends and the water discharging structure is opened, seawater surges into the space between the elevator shaft and the elevator car and enters the electrolytic hydrogen production device through the water inlet. The device starts to electrolyze seawater into oxygen and hydrogen, and the generated oxygen is input into the elevator car through the oxygen outlet to supply oxygen to the people inside the elevator car; and since the density of oxygen is less than that of carbon dioxide, carbon dioxide will deposit at the bottom inside the elevator car. Therefore, the present invention is provided with a gas check valve at the bottom of the elevator car. When the air pressure inside the elevator car is too high, the excess carbon dioxide will be discharged from the gas check valve, keeping the air pressure stable inside the elevator car when the internal oxygen supply is sufficient.

[0019] 3. For the underwater adventure and sightseeing submarine Ferris wheel elevator structure, by arranging an electrolytic hydrogen production device inside the elevator car, the hydrogen generated by the electrolytic hydrogen production device leads to the fuel cell through the hydrogen outlet, starting the electrolysis process. The generated hydrogen is immediately injected into the fuel cell, and the fuel cell can continuously convert hydrogen from chemical energy into electrical energy for other parts of the system to use, reducing the energy consumption of the elevator.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1 - 3, an underwater adventure tour submarine Ferris wheel elevator structure, which is applied to the submarine tour sightseeing project. In this embodiment, the submarine tour project also includes a visitor center above sea level, a suspended restaurant in the ocean, and a submarine tour area at the bottom. As an elevator system, the present invention connects the facilities in the submarine tour project, enabling tourists to take the elevator system in the present invention and move downward from the visitor center on the sea to reach the suspended restaurant or the submarine tour area; the underwater adventure tour submarine Ferris wheel elevator structure includes an elevator shaft 1, an elevator car 2, and a moving platform 6. The upper end of the elevator shaft 1 is connected to the boarding equipment at the upper end of the sea level, and the lower end is connected to the tour cabin inside the ocean. The moving platform 6 is arranged at the lower end of the elevator shaft 1, and the elevator car 2 is located inside the elevator shaft 1. The upper end of the elevator car 2 is connected to the traction machine by a steel wire rope. The lower end of the elevator shaft 1 is provided with a water pumping structure 11, a water discharging structure 12, and a moving platform 6. The water pumping structure 11 includes a water pump 111, and the water discharging structure 12 includes a water valve 121. Both the water pump 111 and the water valve 121 are connected to the inside of the ocean and the inside of the elevator shaft 1; when the elevator car 2 moves upward inside the elevator shaft 1, the water pumping structure 11 starts, and seawater enters the inside of the elevator shaft 1, enabling the elevator car 2 to obtain an upward buoyancy force, effectively sharing the tension that the traction machine needs to bear, thereby significantly reducing the operating power of the traction machine, achieving efficient utilization of energy, and further enhancing the smoothness and safety during the elevator's upward movement; when the elevator car 2 moves downward inside the elevator shaft 1, the water discharging structure 12 starts, and air enters from the upper end of the elevator shaft 1 between the elevator shaft 1 and the elevator car 2, and the seawater is discharged. The decrease in the water level causes the volume of water displaced by the elevator car 2 to become smaller, and the upward buoyancy force it receives becomes smaller. Therefore, it is easier to descend, and the support of the seawater plays a buffering role during the fall of the elevator car 2, effectively slowing down the downward acceleration of the elevator car 2 and avoiding potential safety hazards that may be caused by excessive speed, bringing a more stable and comfortable riding experience for tourists; when the water pumping structure 11 and the water discharging structure 12 are in operation, the lifting mechanism under the moving platform 6 is locked, fixing the moving platform 6 at the connection between the tour cabin and the elevator shaft 1, isolating the seawater in the upper elevator shaft 1 to prevent the seawater from entering the lower tour cabin and achieving sealing; when the elevator car 2 reaches the upper surface of the moving platform 6 and the water pumping structure 11 stops operating, at this time, there is no seawater inside the upper elevator shaft 1, the fixed state between the moving platform 6 and the elevator shaft 1 is released, and the moving platform 6 carries the elevator car 2 and moves downward until it reaches the elevator shaft 1 inside the tour cabin.

[0029] In this embodiment, the depth of the elevator shaft 1 is designed according to the lift distance that the water discharge structure 12 can reach. When the present invention needs to be applied in deeper sea areas, an appropriate water discharge structure 12 should be selected and installed according to specific circumstances. At this time, in addition to the water valve 121, the water discharge structure 12 should also include a pressure balance device to balance the pressure inside and outside the elevator shaft and reduce the structural load. The ballast discharge method can use an air compressor for ballast discharge when safety is ensured.

[0030] An air port communicating the inside and outside is provided at the bottom of the elevator shaft 1 located inside the tour cabin. In actual design, the air output of the air port ensures that the gas at the lower end of the elevator shaft 1 can go out and the air pressure will not be too high, while retaining a part of the air pressure to buffer the fall of the elevator car 2. The moving platform 6 and the inner wall of the elevator shaft 1 are in a sliding and sealing assembly. In this embodiment, a sealing ring is provided on the outer surface of the edge of the moving platform 6 to achieve a sealed contact connection with the inner wall of the elevator shaft 1. The inner part of the lower elevator shaft 2 presents a structure similar to a syringe barrel. The setting of the sealing ring around the moving platform 6 ensures that seawater will not enter the lower tour platform. In actual use, the specific structure of the sealing ring is set according to the usage situation.

[0031] In this embodiment, please refer to Figure 3 and Figure 5 , the elevator car 2 includes an electrolytic hydrogen production device 21 and a hydrogen storage device 22. The hydrogen storage device 22 includes a fuel cell 221. The electrolytic hydrogen production device 21 includes a water inlet 211, an oxygen outlet 212, and a hydrogen outlet 213. The oxygen outlet 212 communicates with the inside of the elevator car 2, the hydrogen outlet 213 communicates with the fuel cell 221, and the water inlet 211 communicates with the space between the elevator shaft 1 and the elevator car 2. Hydrogen is converted from chemical energy to electrical energy inside the fuel cell 221, which can be stored inside the battery. The empty fuel cell 221 is replaced regularly, or it is connected to other devices through an electric circuit to supply energy to them. This is the scheme for storing electrical energy in this embodiment. A seawater desalination filter is provided at the water inlet 211. The specific model of the seawater desalination device is designed according to actual use and is not drawn in the accompanying drawings of the specification. The seawater desalination filter can ensure that the seawater entering the electrolytic hydrogen production device 21 is relatively pure, avoiding the accumulation of impurities and affecting the electrolysis efficiency.

[0032] Please refer to Figure 1 and Figure 2, there are at least two guiding devices 3 provided on the outer surface of the elevator car 2, and the guiding devices 3 are evenly distributed along the outer surface of the elevator car 2; a guiding groove 13 is provided on the inner surface of the elevator shaft 1, the guiding groove 13 is straight and is distributed from top to bottom along the inside of the elevator shaft 1; the guiding device 3 includes a pulley 31, and the pulley 31 is embedded in the guiding groove 13; the number of the guiding devices 3 in the vertical direction in the same plane is not less than two, and the guiding device 3 can ensure that the movement track of the elevator car 2 in the elevator shaft 1 is not affected by the water flow and does not shake. Moreover, since the inner wall of the elevator shaft 1 and the outer wall of the elevator car 2 are both arc-shaped, the guiding device 3 can also enable the elevator car 2 to rotate inside the elevator shaft 1.

[0033] Please refer to Figure 1 and Figure 6 , a lifting mechanism for supporting is provided below the mobile platform 6. In this embodiment, specifically, it is a hydraulic lifting mechanism 61, which is used to support the elevator car 2 and the mobile platform 6 to move together. The mobile platform 6 is fixed to the elevator shaft 1 by locking the hydraulic cylinder. After the locking is released, the mobile platform 6 can descend to the interior of the viewing cabin below the elevator shaft 1; the surface area of the upper surface of the mobile platform 6 is smaller than that of the lower surface. Therefore, a water tank is formed along the perimeter of the upper end of the mobile platform 6, and a pumping structure 11 is provided at the water tank to ensure that all the water on the upper surface of the platform can be pumped away by the pumping structure 11 without affecting the descent of the platform; a liquid level sensor 62 is provided in the water tank along the edge of the mobile platform 6 to detect whether there is still accumulated water in the water tank; during actual use, when the elevator car 2 needs to enter the viewing cabin below, it first stops on the upper surface of the mobile platform 6, and then the pumping structure 11 starts to pump water outwards. Until the liquid level sensor 62 detects that all the seawater in the water tank has been discharged, a signal is sent to the hydraulic lifting mechanism 61, and the hydraulic cylinder in the hydraulic lifting mechanism 61 releases the locked state, and the hydraulic lifting mechanism 61 carries the mobile platform 6 and the elevator car 2 to move downward together. The main power source of the hydraulic lifting mechanism 61 is the hydraulic cylinder. The hydraulic lifting mechanism 61 is a prior art and will not be described in detail here.

[0034] In this embodiment, please refer to Figure 5, a gas check valve 23 is provided at the bottom of the elevator car 2. The gas check valve 23 allows the gas inside the elevator car 2 to be discharged from the elevator car 2. When the elevator ascends and the water discharge structure 12 is opened, seawater surges into the space between the elevator shaft 1 and the elevator car 2 and enters the interior of the electrolytic hydrogen production device 21 through the water inlet 211. The device starts to electrolyze seawater into oxygen and hydrogen, and the generated oxygen is input into the interior of the elevator car 2 through the oxygen outlet 212 to supply oxygen to the people inside the elevator car 2. Moreover, since the density of oxygen is less than that of carbon dioxide, the dioxide will deposit at the bottom inside the elevator car 2. Therefore, the gas check valve 23 is provided at the bottom of the elevator car 2. When the air pressure inside the elevator car 2 is too high, the excess carbon dioxide will be discharged from the gas check valve 23, making the air pressure inside the elevator car 2 stable when there is sufficient internal oxygen supply. In actual use, a gas separation membrane that only allows carbon dioxide to pass through can be provided at the connection between the gas check valve 23 and the elevator car 2. While the excess carbon dioxide is discharged, the other inert gases and gases are retained inside the elevator car 2 to create an air quality that simulates the external environment inside the elevator car 2.

[0035] Please refer to Figure 1 and Figure 4 , both the elevator shaft 1 and the elevator car 2 are transparent structures, enabling tourists to better visit and view the beautiful underwater scenery; the inner and outer surfaces of the elevator shaft 1 and the elevator car 2 are both cylindrical, which can disperse the water pressure from all directions and make the overall structure more stable.

[0036] Please refer to Figure 1 , a locking structure 5 is provided on the inner wall of the elevator shaft 1 at the position where the elevator car 2 needs to stop stably. The locking structure 5 is specifically an electromagnet. A fixing plate 51 made of a magnetizable material is provided on the outer surface of the elevator car 2. When the elevator car 2 moves to the corresponding position and needs to stop, the locking structure 5 is energized to firmly adsorb the fixing plate 51, realizing the locking and stable stop of the elevator car 2 inside the elevator shaft 1 and ensuring the safety of tourists getting on and off the elevator.

[0037] Please refer to Figure 4 , a lighting module 4 is provided on the inner surface of the elevator shaft 1. The lighting module 4 includes induction lights 41; the number of lighting modules 4 is not less than 5 and they are evenly distributed along the straight line direction of the elevator shaft 1. When the elevator car 2 passes by, the induction lights 41 on the lighting module 4 light up to provide lighting for tourists, enabling tourists to clearly view the underwater scenery and at the same time reducing unnecessary power consumption.

[0038] Working principle: When the elevator ascends, the water drainage structure 12 is activated. By using the water valve 121, seawater inside the ocean enters between the elevator shaft 1 and the elevator car 2, enabling the elevator car 2 to obtain an upward buoyant force. When the elevator descends, the water drainage structure 12 is closed and the water pumping structure 11 is opened to pump out the seawater between the elevator shaft 1 and the elevator car 2 and re-drain it into the ocean interior. As the water level drops, the volume of water displaced by the elevator car 2 becomes smaller, and the upward buoyant force it receives becomes smaller, making it easier to descend. When the elevator ascends and the water drainage structure 12 is opened, seawater surges into the space between the elevator shaft 1 and the elevator car 2 and enters the internal electrolytic hydrogen production device 21 through the water inlet 211. The device starts to electrolyze seawater into oxygen and hydrogen, and the generated oxygen is input into the elevator car 2 through the oxygen outlet 212 to supply oxygen to the people inside the elevator car 2. Seawater enters the electrolytic hydrogen production module, starting the electrolysis process. The generated hydrogen is immediately injected into the fuel cell 221, which can continuously convert the remaining hydrogen into electrical energy for other parts of the system to use, or store the electrical energy in the battery to provide electrical energy for the entire device.

[0039] In summary, for this underwater adventure and sightseeing undersea Ferris wheel elevator structure, by controlling the seawater between the elevator shaft 1 and the elevator car 2, and utilizing the buoyant force and the electrolytic hydrogen production device 21, it achieves the triple advantages of reducing the operating power of the traction machine, realizing the efficient utilization of energy, supplying oxygen inside the elevator car 2 to ensure the safety of passengers, and reducing energy consumption by generating electricity using hydrogen.
