Description

Technical Field

[0001] This utility model relates to a submersible, specifically a backpack-type submersible. Background Technology

[0002] In the current diving field, divers primarily rely on fins for underwater movement. This traditional method has significant limitations, resulting in slow movement speed and insufficient flexibility. While propulsion devices are available, they are typically strapped to the arms or legs, making them scattered and inconvenient to use. Furthermore, existing propulsion devices have low integration with oxygen tanks, resulting in poor streamlined design in the water and increased water resistance. This not only affects the diver's operational efficiency but also limits the duration and scope of dive operations. Utility Model Content

The device's design fully considers the diver's agility in the water. Regarding propeller direction control, it features a precise and easy-to-operate control system. Divers can easily adjust the propeller's thrust angle and force using a hand-held sensor controller. Whether surfacing, diving, or making rapid horizontal movements and turns, precise control is possible, as natural and fluid as an extension of the body. This truly enables divers to move more flexibly and freely in the water, bringing higher efficiency and safety to diving operations.

[0033] The present invention will now be described in detail with reference to the embodiments. Those skilled in the art should know that the following embodiments are not the only limitation on the technical solution of the present invention. Any equivalent transformations or modifications made under the spirit and essence of the technical solution of the present invention should be considered as falling within the protection scope of the present invention.

[0034] This utility model provides a backpack-style diving device, such as Figure 1As shown, the submersible includes a main hull 1, shoulder assembly 2, tail assembly 3, air tank 4, wing propeller assembly 5, tail propeller assembly 6, servo system 7, controller assembly 8, and power supply assembly 9. It also includes a handheld controller, which connects to the controller and other electronically controlled components such as solenoid valves. The handheld controller has function buttons such as: ascend / descend, speed increase / decrease, safety mode, and emergency ascent, allowing the submersible to control its free ascent or descent at a certain speed, safe ascent or descent, and emergency ascent functions. These functions are easily accessible and can be quickly switched. Each function is linked to the propulsion power, steering, and airbag intake and exhaust.

[0035] The submersible is assembled around the main hull 1, and a complete equipment structure is formed through the orderly combination of various functional components (power, control, power supply, and gas cylinders).

[0036] The main hull 1 is made of 304 stainless steel with a plate thickness of 1mm. The main hull 1 consists of two parts: the main compartment and the upper cover. The main compartment serves as the main supporting structure of the whole structure. The center is used to house the gas cylinder 4, and the sides are used to house electrical components such as the servo system 7, controller assembly 8, and power supply assembly 9. The upper cover covers the main compartment, forming a closed protection for the internal structure. Figure 2 The image shown is a top view of the main housing 1 without the top cover.

[0037] With the central gas cylinder installation position as the center of symmetry, the main housing 1 has a set of shoulder components 2 on each side of the shoulder, and similarly, a set of tail components 3 on each side of the tail, forming the head and tail structural frame of the equipment.

[0038] Gas cylinder 4 is placed inside the main hull 1, and the tail propeller assembly 6 is installed on the tail support of the gas cylinder to coordinate and change the direction of the submersible, thus completing the integration of the overall power system.

[0039] The wing-mounted propeller assemblies 5 are symmetrically mounted on both sides of the main housing 1, controlled by servos, providing power and changing the course of the flight. The controller assembly 8 and the power supply assembly 9 are installed inside the main housing 1, responsible for control and power supply functions, respectively.

[0040] This utility model backpack-type submersible uses a single air cylinder to reduce the overall weight of the submersible. It still uses a three-rotor propulsion system with two shoulder propulsion units and one tail propulsion unit. However, the tail propulsion unit is fixed and its direction is not adjustable. Only the two shoulder propulsion units can change direction. Therefore, the wing propeller assembly 5 is controlled by a servo motor.

[0041] The servo system 7 includes a motor, transmission mechanism, and control circuitry, such as... Figure 1 , Figures 3-5 As shown, it includes a servo housing 71, a fixed sheet metal part 72, a servo motor 73, a steering shaft 74, a bearing housing 75, a bearing housing 76, and a seal 77.

[0042] The servo housing 71 is fixed inside the main housing 1, and the fixed sheet metal part 72 is fixed inside the servo housing 71. The fixed sheet metal part 72 is used to fix the servo 73. The output end of the servo 73 is connected to the steering shaft 74 through a coupling. The steering shaft 74 extends out of the servo housing 71 and is connected to the propeller assembly 5 of the wing.

[0043] The servo housing 71 provides enclosed protection for the servo motor and is connected to the bearing housing 75 via bolts or other means, providing support and positioning for the steering shaft. The servo housing is a sealed enclosure and a protective component. Inside, it houses the control circuit board, cables, and power management module, protecting internal electronic components, centrally controlling the servo system, and providing a supporting mounting structure for the entire servo system.

[0044] The fixed sheet metal part 72 mainly serves to support and fix the servo motor. At the same time, it is connected to the bearing housing 75 by means of bolts and other methods, and also provides support and positioning for the steering shaft. The fixed sheet metal part 72 securely installs the servo motor in the designated position, ensuring that the servo motor will not be displaced during operation and guaranteeing the structural stability of the entire device.

[0045] The bearing housing 75 is installed between the servo housing 71 and the fixed sheet metal part 72 via bolt connections or other means. A bearing seat 76 is installed inside the bearing housing 75 to pass through the steering shaft 74, ensuring the sliding capability of the steering shaft 74. The bearing housing 75 is installed within the servo housing and related support structures, and its inner diameter is adapted to the steering shaft 74, providing radial support and axial positioning for the steering shaft, ensuring its stability during rotation and reducing axial and radial wobble. The bearing seat 76 is made of nylon and is itself a sliding bearing, installed within the bearing housing. The steering shaft is installed inside the bearing seat, improving its rotational accuracy and stability, reducing friction, and allowing for smooth rotation. A seal 77 is provided at the connection point between the bearing housing 75 and the servo housing 71, passing through the steering shaft 74 to ensure a seal between the steering shaft 74 and the servo housing 71. The seal 77 is installed at the mating point between the steering shaft and the servo box. Its function is to prevent water, dust and other impurities from entering the device and to protect the internal precision components. It is usually made of elastic materials such as rubber and is tightly fitted to the surface of the steering shaft and the mounting part to ensure a sealing effect.

[0046] Servo 73 is a power source component, mounted on a fixed sheet metal part. When the servo is working, it outputs torque, which is transmitted to the steering shaft 74 through a coupling, driving the steering shaft to rotate, thereby realizing the steering or power output function of related components.

[0047] The steering shaft 74 is a connecting component of the servo system, which plays the role of transmitting power and determining direction. One end of it is connected to the coupling, and the other end passes through multiple components to connect to the two-wing propeller assembly 5. The shaft has specific positioning structures (such as keyways) for precise positioning and connection with the bearing housing.

[0048] Wing propeller assembly 5, such as Figure 6 As shown, the system includes a propeller motor housing 51, a propeller motor, and a wing propeller 52. The propeller motor housing 51 is fixedly connected to a steering shaft 74 to control the oscillation direction. The propeller motor is installed inside the propeller motor housing 51, and the propeller motor drives the wing propeller 52, which is located outside the housing, to rotate. The servo system can change the direction of the propeller thrust according to the control signal, and the rotation of the propeller generates a rearward thrust.

[0049] The wing propeller assembly 5 is symmetrically arranged on both sides of the main hull 1, and the tail propeller assembly 6 is located at the tail of the main hull 1. The three propellers control the submersible to move forward smoothly.

[0050] The tail propeller assembly 6 is installed at the tail of the gas cylinder, such as... Figure 1 and 7 As shown, the system includes a tail support 61 for the gas cylinder, a tail propeller motor, and a tail propeller 62. The tail support 61 covers the tail of the gas cylinder and conforms to the shape of the tail of the gas cylinder 4, having a gradually tapering streamlined shape. This shape reduces water resistance during movement in water. The tail support 61 is fixed to the main housing 1, and the propeller motor is fixedly mounted on the tail support 61, driving the tail propeller 62. The tail propeller 62 is mounted at a fixed angle and cannot swing like a two-bladed propeller.

[0051] The streamlined shape of the gas cylinder's tail end greatly reduces the submersible's drag in the water. When the submersible carries the gas cylinder, the water flows more smoothly over the tail end of the cylinder, reducing turbulence and eddies, thereby reducing energy loss and improving the submersible's endurance and operational efficiency.

[0052] Shoulder component 2, such as Figure 8 As shown, the shoulder assembly 2 consists of a shoulder shell 21, a shoulder cover assembly 22, and an airbag. The shoulder shell is welded from 304 stainless steel plate with a thickness of 1mm. In underwater and other fluid environments, the water-facing surface of the shoulder shell is designed with a gradually tapering arc shape to reduce water flow resistance. Numerous holes are distributed on the shoulder shell 21, which perform a crucial function—water inlet and outlet. During the submersible's descent, the holes allow water to flow in smoothly, balancing internal and external water pressure and ensuring the structural safety of the equipment. During ascent, they allow accumulated water to drain quickly, helping the submersible adjust its buoyancy and ensuring stable operation and flexible control in the water.

[0053] The shoulder cover assembly 22 is a cover assembly located on the side of the shoulder housing 21. The shoulder cover assembly 22 mainly consists of a shoulder end cap, an air connector, and a solenoid valve. The air connector is installed on the shoulder end cap, and the solenoid valve is installed on the air connector. The airbag is located inside the shoulder housing and has two air nozzles. There are correspondingly two air connectors. One air connector is connected at one end to one air nozzle of the airbag, and the other end is connected to a gas cylinder via an external air tube. An inlet solenoid valve is installed on this air connector; when the valve is open, air can enter, increasing the airbag and displacing water from the shoulder assembly. The other air connector is connected at one end to the other air nozzle of the airbag, with the other end open. An exhaust solenoid valve is installed on this air connector; when the valve is open, gas can be expelled from the airbag, allowing water to enter the shoulder assembly. The valve body enables rapid inflation and deflation of the airbag, thus meeting the needs of related equipment for adjusting the airbag's state under different operating conditions.

[0054] In dangerous situations, the input and output of gas are controlled by a solenoid valve, adjusting the airbag volume to allow the backpack-style submersible to float independently in the water. When surfacing is required, gas is input into the airbag, increasing its volume, expelling water from the shoulder assembly, generating buoyancy, and better cooperating with the wing-propeller assembly 5 to change direction. When the submersible needs to descend, gas is released into the water, reducing its volume, and water is drawn into the shoulder assembly, better cooperating with the wing-propeller assembly 5 to change direction and allow the submersible to descend.

[0055] Similarly, tail component 3, such as Figure 9 As shown, it consists of a tail shell 31 and a tail cover assembly 32, with an airbag also housed inside the tail shell. The tail shell 31 is welded from 1mm thick 304 stainless steel sheet. To reduce resistance in underwater and other fluid environments, the tail end of the tail shell is designed as a gradually tapering arc. Numerous holes are also distributed on the tail shell 31, which serve the functions of water inlet and drainage.

[0056] The tail cover assembly 32 is located on the side of the tail housing 31. Similarly, the tail cover assembly 32 mainly consists of a tail end cover, an air connector, and a solenoid valve. The air connector is installed on the tail end cover, and the solenoid valve is installed on the air connector. The airbag is located inside the tail housing and has two air nozzles. There are two air connectors. One end of the air connector is connected to one air nozzle of the airbag, and the other end is connected to the gas cylinder through an external air tube. An air intake solenoid valve is installed on this air connector. When the valve is open, air can enter, increasing the airbag and displacing the water in the tail assembly. The other air connector is connected to the other air nozzle of the airbag, and the other end is open. An air exhaust solenoid valve is installed on this air connector. When the valve is open, the gas in the airbag can be discharged, and water can enter the tail assembly. The solenoid valve enables rapid inflation and deflation of the airbag, thereby meeting the needs of related equipment to adjust the airbag status under different operating conditions.

[0057] Depending on the underwater operation conditions, by changing the volume of the tail airbag and the shoulder airbag, the backpack-style submersible can rise vertically upwards and stand upright in the water at a certain safe speed, so that the person's head emerges from the water first, ensuring personal safety.
