Description

Technical Field

[0001] The invention belongs to the technical field of diving equipment, and in particular relates to an underwater sightseeing submarine. Background Art

[0002] With the booming development of the global tourism industry, sightseeing in lakes and offshore areas has become a popular leisure activity. At present, as the main means of transportation for water tours, sightseeing boats carry tourists to sail on the water, enjoy the natural beauty of the water, and enjoy the baptism and relaxation of the soul. With the continuous progress of social economy and the significant improvement of people's living standards, people's demand for tourism experience has changed from simple visual enjoyment to a deeper spiritual pursuit. Against this background, the development of the tourism industry has shown a trend of diversification and high quality. Among them, water entertainment facilities have attracted more and more attention with their unique charm. In the face of the underwater world, some people are full of curiosity and desire to explore, eager to experience the fantasy and magnificence of the seabed in person, so as to enrich their personal spiritual world and broaden their horizons.

[0003] In order to meet tourists' demand for underwater exploration, sightseeing submarines that can dive into the water and view underwater scenery have come into being. Sightseeing submarines are designed based on the design concept of submarines, but they are smaller in size, simpler in structure and function, and can provide tourists with underwater sightseeing experience.

[0004] However, submarines are highly integrated, and in the event of danger, people can use pre-prepared emergency escape boats to escape. However, the space on sightseeing submarines is limited, and it is very difficult to carry emergency escape boats. In addition, the communication signal on the seabed is poor, and it is difficult to contact rescue personnel in the event of danger. Therefore, once a sightseeing yacht breaks down, it is difficult to escape, and the safety of tourists' lives and property cannot be guaranteed.

[0005] Therefore, we propose an underwater sightseeing submarine to solve the above technical problems. Summary of the invention

The escape airbag will expand immediately after inflation, and after the cockpit and the equipment compartment are separated, the buoyancy can be enhanced, providing strong support for emergency escape from the cockpit.

[0022] 5. The present invention uses the locking mechanism of the electromagnetic locking mechanism, so that the cockpit can be easily and efficiently disassembled and reassembled, which is beneficial to subsequent inspection and maintenance work. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 5The present invention provides an underwater sightseeing submarine, comprising a cockpit 1, an equipment cabin 2, a floating and sinking water tank 3 and a power mechanism, wherein the cockpit 1 is spherical, a groove 4 is provided on the top surface of the equipment cabin 2, the cockpit 1 is installed in the groove 4 on the equipment cabin 2, a hatch 5 is provided on the top of the cockpit 1, and a plurality of sightseeing windows 6 are provided on the side walls of the cockpit 1, a driving system is arranged in the cockpit 1, an electromagnetic locking mechanism with strong adsorption ability after power is turned on is provided on the equipment cabin 2, the equipment cabin 2 fixes the cockpit 1 on the equipment cabin 2 through the electromagnetic locking mechanism, a control and power supply system is arranged in the equipment cabin 2, the floating and sinking water tank 3 is installed on both sides of the equipment cabin 2, a water inlet and outlet system is arranged in the floating and sinking water tank 3, a power mechanism is installed on the floating and sinking water tank 3, the equipment cabin 2 and the cockpit 1, and the driving system, the electromagnetic locking mechanism, the water inlet and outlet system and the power mechanism are all electrically connected to the control and power supply system.

[0032] The underwater sightseeing submarine adopts a spherical design and is installed in the groove 4 on the top surface of the equipment cabin 2. The equipment cabin 2 is provided with an electromagnetic locking mechanism. When powered on, the electromagnetic locking mechanism can generate a strong adsorption force to firmly lock the cockpit 1 in the groove 4 of the equipment cabin 2. During the dive, the cockpit 1, the equipment cabin 2 and the floating and sinking water tank 3 respectively assume the functions of control, floating, operation control, propulsion and attitude adjustment of the sightseeing submarine through the driving system, water inlet and outlet system, control and power supply system, and power mechanism configured inside them. Through the efficient coordination of the cockpit 1, the equipment cabin 2, the floating and sinking water tank 3 and the power mechanism, an efficient operation system of the sightseeing submarine is jointly constructed, and the efficiency, safety and comfort of the submarine during underwater sightseeing are jointly ensured, bringing tourists an unparalleled underwater adventure experience. In order to accurately control the movement and attitude adjustment of the sightseeing submarine, power mechanisms are installed on the floating and sinking water tank 3, the equipment cabin 2 and the cockpit 1, which together provide strong and stable propulsion for the movement and attitude control of the sightseeing submarine. When the sightseeing submarine encounters an emergency underwater, if the control and power supply system does not fail, the accompanying staff can manually control the electromagnetic locking mechanism to cut off the power. At this time, the electromagnetic locking mechanism loses its adsorption force, and the cockpit 1 will be easily separated from the groove 4 of the equipment cabin 2 under the buoyancy of the water body, and float to the surface to complete the emergency escape. Even if the control and power supply system fails, the electromagnetic locking mechanism will automatically lose its adsorption force due to power failure, so that the cockpit 1 can also be smoothly separated from the equipment cabin 2. In addition, the electromagnetic locking mechanism used in this underwater sightseeing submarine responds quickly, which can provide tourists and accompanying staff with valuable escape time and more reliable safety protection. Through the locking mechanism of the electromagnetic locking mechanism, the cockpit 1 can be easily and efficiently disassembled and reassembled, which is conducive to subsequent inspection and maintenance work. Compared with traditional sightseeing submarines, this underwater sightseeing submarine effectively solves the problem of difficulty in carrying an escape boat due to space problems, which makes it difficult to escape after danger occurs, and provides a more solid guarantee for the safety of life and property of tourists. It is worth mentioning that the purpose of using multiple sightseeing windows 6 on the cockpit 1 is to control costs and ensure the strength of the cockpit 1, thereby improving the safety of the cockpit 1 underwater. Without considering the cost, high-strength transparent materials are used to manufacture the cockpit 1, and the cockpit 1 can be transformed into a panoramic observation mode, so that tourists can get a better sightseeing experience.

[0033] Among them, the driving system, water intake and drainage system, and control and power supply system involved in the sightseeing submarine all adopt conventional technical means in the existing technology, which can be fully implemented by technical personnel in the field, so they will not be repeated here.

[0034] In a specific embodiment, see Figure 4 and Figure 5The electromagnetic locking mechanism includes a lower clamping seat 7 and an upper clamping seat 8, and the sides of the lower clamping seat 7 and the upper clamping seat 8 facing the cockpit 1 are matched with the shape of the cockpit 1. The lower clamping seat 7 is fixedly installed on the top surface of the equipment cabin 2, and the top surface of the lower clamping seat 7 is provided with a first electromagnet 9, and the first electromagnet 9 is electrically connected to the control and power supply system. The upper clamping seat 8 and the lower clamping seat 7 are hinged through a hinge shaft 10, and the bottom surface of the upper clamping seat 8 is provided with a first magnetic plate 11 that matches the first electromagnet 9, and the upper part of the upper clamping seat 8 is connected to a fixing plate 12 that can abut against the top surface of the cabin door 5.

[0035] The side of the lower clamping seat 7 and the upper clamping seat 8 facing the cockpit 1 are matched with the shape of the cockpit 1, ensuring that the electromagnetic locking mechanism can fit the cockpit 1 tightly when closed, thereby providing a stable locking effect. Specifically, the lower clamping seat 7 and the upper clamping seat 8 are hinged by the hinge shaft 10. After power is turned on, the lower clamping seat 7 and the upper clamping seat 8 are firmly adsorbed together by the attraction of the first electromagnet 9 and the first magnetic plate 11. At this time, the fixing plate 12 above the upper clamping seat 8 abuts against the top surface of the cabin door 5, effectively fixing the cockpit 1 on the equipment cabin 2. In the case of power failure, the first electromagnet 9 and the first magnetic plate 11 lose their adsorption force, the cockpit 1 floats up under the action of buoyancy, and the upper clamping seat 8 rotates outward after being thrust, thereby allowing the cockpit 1 to smoothly detach from the equipment cabin 2 and float to the surface of the water, completing emergency escape.

[0036] In a specific embodiment, the first magnetic plate 11 is one of a neodymium iron boron strong magnet, a samarium cobalt magnet, an iron chromium cobalt magnet, a permanent ferrite magnet and an aluminum nickel cobalt magnet.

[0037] NdFeB strong magnets, samarium cobalt magnets, iron-chromium-cobalt magnets, permanent ferrite magnets and aluminum-nickel-cobalt magnets all have strong magnetism. After the first electromagnet 9 is energized, the first magnetic plate 11 made of these strong magnets can be well adsorbed together, thereby firmly fixing the cockpit 1 on the equipment compartment 2, providing a solid guarantee for the safe operation of the sightseeing submarine.

[0038] In a specific embodiment, see Figure 2 A second electromagnet 13 is provided in the groove 4 , and the second electromagnet 13 is electrically connected to the control and power supply system. A second magnetic plate 14 matching with the second electromagnet 13 is provided on the bottom surface of the cockpit 1 .

[0039] Similarly, the bottom surface of the cockpit 1 and the groove 4 are firmly adsorbed together with the second magnetic plate 14 and the second electromagnet 13 through the electromagnetic attraction mechanism. When the second electromagnet 13 is energized, it further improves the connection stability between the cockpit 1 and the equipment compartment 2.

[0040] In a specific embodiment, see Figure 1 , Figure 4 and Figure 5 The power mechanism includes a main propeller 15, a horizontal propeller 16 and a vertical propeller 17. The main propeller 15 is installed at the tail of the floating tank 3, the horizontal propeller 16 is symmetrically installed on both sides of the equipment cabin 2, and the vertical propeller 17 is symmetrically installed on both sides of the cockpit 1. The main propeller 15, the horizontal propeller 16 and the vertical propeller 17 are all electrically connected to the control and power supply system.

[0041] The main propeller 15 is installed at the tail of the floating water tank 3, which is responsible for providing the main power for the sightseeing submarine to move forward or backward, ensuring that the submarine can move quickly and stably underwater. The horizontal propeller 16 and the vertical propeller 17 are auxiliary propellers. The horizontal propeller 16 is symmetrically installed on both sides of the equipment compartment 2, and its propulsion direction is the same as that of the main propeller 15. It can be used with the main propeller 15 to achieve acceleration or deceleration. In addition, by controlling the speed difference of the horizontal propellers 16 on both sides, the turning action of the sightseeing submarine can be realized. The vertical propeller 17 is symmetrically installed on both sides of the cockpit 1, which can provide the propulsion force for the sightseeing submarine to move up and down in the underwater environment, and by controlling the speed difference of the vertical propellers 17 on both sides, the posture adjustment of the sightseeing submarine can be realized. By accurately controlling the coordinated work of the main propeller 15, the horizontal propeller 16 and the vertical propeller 17, the sightseeing submarine can flexibly adjust its course in the water, easily cope with various complex underwater environments, and meet various complex driving needs.

[0042] In a specific embodiment, see Figure 2 , also includes an emergency system, the emergency system includes an emergency control switch 18 and an emergency power supply 19, a manned platform 20 is provided inside the cockpit 1, the emergency control switch 18 and the emergency power supply 19 are respectively arranged on the upper and lower sides of the manned platform 20, and the emergency control switch 18 and the emergency power supply 19 are both electrically connected to the vertical thruster 17.

[0043] When encountering an emergency underwater, the cockpit 1 can quickly detach from the equipment compartment 2, and the emergency power supply 19 in the cockpit 1 will be immediately started to provide power to the vertical thruster 17. The vertical thruster 17 can be controlled by the emergency control switch 18 to adjust the ascent speed and posture of the cockpit 1 in the water, ensuring that the cockpit 1 and the personnel inside can safely surface or avoid potential danger areas, thereby maximizing the safety of the personnel inside.

[0044] In a specific embodiment, see Figure 2 A sealed cabin 21 is provided above the manned platform 20 , and the cockpit 1 is divided into a cockpit 22 and a sightseeing room 23 by the sealed cabin 21 .

[0045] The cockpit 1 is divided into a driving room 22 and a sightseeing room 23 by a sealed cabin panel 21, which not only ensures the operating space for the accompanying staff and provides a strong guarantee for safe driving, but also provides an underwater sightseeing area for tourists.

[0046] In a specific embodiment, see Figure 2 and Figure 3 An air pump 24 and an air storage tank 25 are provided below the manned platform 20. An air inlet pipe 26 and an air outlet pipe 27 are provided on the air pump 24. The air outlet pipe 27 is communicated with the sightseeing room 23. The emergency control switch 18 and the emergency power supply 19 are both electrically connected to the air pump 24. An air supply pipe 28 is provided on the air storage tank 25. An escape airbag 29 is provided at one end of the air supply pipe 28. An airbag chamber 30 is provided at the bottom of the cockpit 1. The escape airbag 29 is located in the airbag chamber 30. An air closing valve 31 is provided on the air supply pipe 28. The air closing valve 31 is electrically connected to the control and power supply system.

[0047] When an underwater emergency occurs and the control and power supply system fails, the air-locking valve 31 will automatically open due to power failure, causing the oxygen stored in the air tank 25 to be quickly released outward through the air supply pipe 28. At this time, the oxygen released outward can quickly inflate the escape airbag 29 through the air supply pipe 28. The escape airbag 29 expands immediately after inflation, and after the cockpit 1 is separated from the equipment cabin 2, the buoyancy can be enhanced, providing strong support for the emergency escape of the cockpit 1. At the same time, the emergency power supply 19 can provide electrical energy for the inflation pump 24, and the emergency control switch 18 can be used to fill part of the oxygen into the sightseeing room 23 to meet the breathing needs of the internal personnel in an emergency and ensure their basic life safety.

[0048] In a specific embodiment, see Figure 1 , Figure 4 and Figure 5 A flash light belt 32 is provided on the outer side wall of the sightseeing window 6.

[0049] The arrangement of the flashing light strip 32 can not only attract various fish schools in the sea area to approach, but also provide tourists with the experience of watching marine life up close, which greatly enriches the fun and viewing of the sightseeing submarine. Moreover, in an emergency, when the sightseeing submarine floats to the surface, the flashing light strip 32 quickly turns into a striking help signal light, sending a clear help signal to the surroundings, thereby quickly attracting the attention of the rescue team, and improving the efficiency and safety of emergency response.

[0050] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
