Technical Field
[0001] This utility model belongs to the field of marine equipment, and specifically relates to a powered submersible with a box-within-a-box waterproof design. Background Technology
[0002] A boat is a tool for traveling on water. With the development of the times, there are many types of boats. Among them, portable boats are designed to meet the needs of individuals for small boats used on water.
[0003] A prior patent discloses a portable surface patrol boat for hydropower plants (application number CN201520194586.X), which includes a hull. The hull's interior cavity is evenly spaced with partitions to divide the cavity. The hull and bottom of this portable surface patrol boat are equipped with multiple airbags and multiple bottom airbags, respectively. These airbags and bottom airbags work together to support the hull, ensuring that even if one airbag or bottom airbag ruptures, the boat will not sink. The hull and bottom are each equipped with an anti-corrosion layer, which not only strengthens the hull structure but also protects the interior from water erosion. Reinforcing airbags within the hull cavity further enhance the overall structural strength. The hull is equipped with a propeller and a speedboat motor. The speedboat motor allows for rapid movement, while the propeller can be used in shallow water, offering convenience and ease of use. However, the vessel disclosed in this prior patent only has the function of carrying a user on the surface and lacks diving assistance features, making its functionality relatively limited. Summary of the Invention
[0004] To address the aforementioned issues, the primary objective of this invention is to provide a waterproof, box-within-a-box powered submersible. This submersible not only carries users on the water's surface but also provides diving assistance, offering a wider range of functions to meet diverse user needs.
[0005] Another objective of this invention is to provide a powered submersible with a box-within-a-box waterproof design, which has a compact structure and smaller size.
[0006] A waterproof powered submersible with a box-within-a-box design, characterized in that it comprises:
[0007] The hull has a carrying position for carrying users on its upper side;
[0008] A propulsion unit, wherein the propulsion unit is disposed on the underside or rearside of the hull;
[0009] An air supply system includes a water storage box, an air inlet pipe, and an air outlet pipe, all of which are located within the hull. The water storage box contains a water storage chamber. One end of the air inlet pipe and one end of the air outlet pipe form an air inlet and an air outlet on the hull, respectively. The other end of the air inlet pipe is connected to the upper end of the water storage chamber, and the other end of the air outlet pipe is connected to the lower end of the water storage chamber.
[0010] A control box is disposed inside the water storage chamber, and the control box is equipped with a control system for controlling the operation of the thruster, the control system being connected to the thruster.
[0011] This submersible, equipped with both a propulsion system and an air supply system, allows users to move on the surface via the propulsion system when needed. When diving, the user can connect the diving mask to the vent via a trachea and descend to breathe through the air supply system. In other words, this submersible combines surface propulsion with underwater assisted diving capabilities, offering a wider range of functions to meet various needs such as surface and underwater emergency rescue, underwater topographic exploration, salvage, fishing, and search and rescue in nearby waters. Furthermore, the control box is housed within the water storage chamber of the water tank, resulting in a compact structure and smaller size; the size of the water tank can also be increased as needed.
[0012] Furthermore, the submersible also includes a water level switch for monitoring the liquid level in the water storage chamber, the water level switch being electrically connected to the control system.
[0013] Furthermore, both the water storage cavity and the control box are rectangular in shape, with the control box obliquely disposed within the water storage cavity so that the four sides of the control box are inclined relative to the corresponding four sides of the water storage cavity.
[0014] Furthermore, the air outlet pipeline includes an air pump, a first air outlet pipe, and a second air outlet pipe. The air pump is electrically connected to the control system. One end of the first air outlet pipe and one end of the second air outlet pipe are both connected to the air pump. The other end of the first air outlet pipe is connected to the upper end of the water storage chamber. The other end of the second air outlet pipe extends out of the hull to form the air outlet.
[0015] Furthermore, the other end of the first vent pipe extends into the water storage chamber and then bends upwards to connect with the upper end of the water storage chamber.
[0016] Furthermore, the other end of the second vent pipe extends from below the water storage cavity to form the vent on the hull.
[0017] Furthermore, the submersible also includes a pressure switch for monitoring the air pressure in the second vent pipe, the pressure switch being connected to the second vent pipe and electrically connected to the control system.
[0018] Furthermore, the submarine also includes a pressure ball for storing gas, which is connected to the second vent pipe.
[0019] Furthermore, the hull is equipped with multiple shoulder strap fixing handles. The shoulder strap fixing handles can be fixed with shoulder straps so that the user can carry it on their back for easy carrying; in other implementations, the shoulder strap fixing handles are also replaced with handles for easy carrying.
[0020] Furthermore, the hull is equipped with a charging port that is electrically connected to the control system.
[0021] Furthermore, the hull is equipped with a magnetic switch that is electrically connected to the control system.
[0022] Furthermore, the hull is equipped with a push-button switch that is electrically connected to the control system.
[0023] Furthermore, the hull is equipped with a display screen that is electrically connected to the control system.
[0024] Furthermore, the hull is also provided with a drain outlet for connecting to the water storage chamber.
[0025] Furthermore, the number of air pumps is one, two, or three or more.
[0026] Furthermore, the number of the thrusters is one, two, or three or more.
[0027] The beneficial effects of this invention are as follows: This submarine, equipped with both a propulsion system and an air supply system, allows the user to move on the surface via the propulsion system when needed. When diving, the user can connect the diving mask to the air vent via a trachea and descend within the trachea's range to breathe through the air supply system. In other words, this submarine possesses both surface propulsion and underwater assisted diving capabilities, offering a wider range of functions to meet various needs such as surface and underwater emergency rescue, underwater topographic exploration, salvage, fishing, and search of nearby waters. Furthermore, the control box's placement within the water storage chamber of the water tank allows for a compact structure and smaller size; the water storage tank's volume can also be increased as needed.

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0042] See Figure 1-6 This embodiment provides a powered submersible with a box-within-a-box waterproof design, comprising:
[0043] The hull 1 has a carrying position 11 for carrying users on its upper side;
[0044] Thruster 2 is located on the lower or rear side of hull 1;
[0045] The gas supply system 3 includes a water storage box 31, an air inlet pipe 32, and an air outlet pipe 33. The water storage box 31, air inlet pipe 32, and air outlet pipe 33 are all located inside the hull 1. The water storage box 31 is provided with a water storage cavity 311. One end of the air inlet pipe 32 and one end of the air outlet pipe 33 form an air inlet 321 and an air outlet 331 on the hull 1, respectively. The other end of the air inlet pipe 32 is connected to the upper end of the water storage cavity 311, and the other end of the air outlet pipe 33 is connected to the lower end of the water storage cavity 311. The air inlet pipe 32 and the air outlet pipe 33 are staggered within the water storage cavity 311.
[0046] The control box 4 is located inside the water storage chamber 311 and contains a control system for controlling the operation of the thruster 2. The control system is connected to the thruster 2.
[0047] Specifically, the circuit design and control program design of the control system are conventional technologies, and therefore will not be elaborated in this application. Figure 1 In the diagram, the dashed lines represent circuit connections.
[0048] In this embodiment, the submersible also includes a water level switch 5 for monitoring the liquid level in the water storage chamber 311. The water level switch 5 is electrically connected to the control system. When the water level in the water storage chamber 311 touches the water level switch 5, it will trigger the water level switch 5, activating protection to shut down the pump through the control system, thus protecting the pump from damage.
[0049] In this embodiment, both the water storage cavity 311 and the control box 4 are rectangular in shape. The control box 4 is obliquely disposed inside the water storage cavity 311 so that the four sides of the control box 4 are relatively inclined to the corresponding four sides of the water storage cavity 311. This oblique side-mounted arrangement of the control box 4 can more effectively prevent water vapor from flying around inside the water storage cavity 311, and can more effectively prevent water from being drawn in through the air supply system 3.
[0050] In this embodiment, the air outlet pipe 33 includes an air pump 332, a first air outlet pipe 333, and a second air outlet pipe 334. The air pump 332 is electrically connected to the control system. One end of the first air outlet pipe 333 and one end of the second air outlet pipe 334 are both connected to the air pump 332. The other end of the first air outlet pipe 333 is connected to the upper end of the water storage chamber 311. The other end of the second air outlet pipe 334 extends out of the hull 1 to form an air outlet 331.
[0051] In this embodiment, the control box 4 may also be equipped with a battery for electrical connection with the control system to provide power to the submarine. Specifically, the battery in the control box 4 may be a set of 24-volt batteries, which directly supply the thruster 2 with 24 volts and supply the air pump 332 with 12 volts through a step-down converter. The power is shared, and the energy ratio used by the thruster 2 and the air pump 332 can be freely controlled. Moreover, the assembly is simpler and more energy-efficient.
[0052] In this embodiment, the other end of the first vent pipe 333 extends into the water storage chamber 311 and then bends upward so that the upper end of the pipe extends into the water storage chamber 311 and connects with the water storage chamber 311.
[0053] In this embodiment, the other end of the second vent pipe 334 extends out of the hull 1 after passing below the water storage cavity 311 to form a vent 331.
[0054] In this embodiment, the submersible also includes a pressure switch 6 for monitoring the air pressure of the second air outlet pipe 334. The pressure switch is connected to the second air outlet pipe 334 and electrically connected to the control system. The pressure switch 6 is configured to shut down the pump via the control system when the air pressure in the second air outlet pipe 334 reaches 4 atmospheres, in order to prevent excessive air pressure.
[0055] In this embodiment, the submersible also includes a pressure ball 7 for gas storage, which is connected to the second air outlet pipe 334. The pressure ball 7 ensures a stable gas supply and also has a certain gas storage function, which can provide stored gas to help divers ascend in emergency situations such as pump failure.
[0056] In this embodiment, the hull 1 is provided with a plurality of shoulder strap fixing handles 12. The shoulder strap fixing handles 12 can be fixed with shoulder straps so that the user can carry them on their back for easy carrying; in other implementations, the shoulder strap fixing handles 12 can also be replaced with handles for easy carrying.
[0057] In this embodiment, the hull 1 is provided with a charging port 13 that is electrically connected to the control system. The charging port 13 can be used to charge the battery.
[0058] In this embodiment, a magnetic control switch 14 electrically connected to the control system is provided on the hull 1. The magnetic control switch 14 is configured such that the thruster 2 can be activated by pressing the sensing area of the magnetic control switch 14, and can be immediately deactivated when released.
[0059] In this embodiment, a push-button switch 15 electrically connected to the control system is provided on the hull 1. The push-button switch 15 can be used to operate the control system. The push-button switch 15 may include a breathing switch 151 and a thruster switch 152, to control the operation of the air pump 332 and the thruster 2, respectively.
[0060] In this embodiment, a display screen 16 electrically connected to the control system is provided on the hull 1.
[0061] In this embodiment, the hull 1 is also provided with a drain outlet 17 for connecting to the water storage chamber 311. The drain outlet 17 is a normally closed manual drain outlet 17; in other implementations, it can also be an automatic drain outlet 17 that automatically drains water via a water pump.
[0062] In this embodiment, the number of air pumps 332 is one, two, or three or more; the number of thrusters 2 is one, two, or three or more; the number of air pumps 332 and thrusters 2 can be set according to usage requirements.
[0063] In this embodiment, the hull 1 is made of EVA material, but in other implementations it can also be made of materials such as aluminum, stainless steel, or plastic.
[0064] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
