[0048] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0049] The diving device is used to enable the hull to descend from the surface to underwater.

[0050] In related technologies, the submersible mainly consists of a hull, a control compartment, and a water pump. During assembly, the control compartment and the water pump are located inside the hull. The water pump is used to draw seawater from the outside into the control compartment, thereby increasing the weight of the control compartment and allowing the hull to submerge underwater under the weight of the control compartment.

[0051] However, due to the limited size of the control cabin, the overall weight is limited when the control cabin is loaded with seawater, which results in a slower descent speed during the descent.

[0052] To address the aforementioned technical problems, this disclosure provides a submersible device. Figure 1 See the schematic diagram of the submersible device. Figure 1 In this embodiment, the submersible includes a shell 1, a telescopic assembly 2, an air duct system 3, and a pressure relief pipe 4. The shell 1 has a water storage chamber 11 and a accommodating chamber 12. The first end of the telescopic assembly 2 is connected to the shell 1. The pressure relief pipe 4 is connected to the second end of the telescopic assembly 2. The pipe wall of the pressure relief pipe 4 has a plurality of pressure relief holes 41 arranged at intervals. The air duct system 3 includes an air inlet pipe 31, an air outlet pipe 32, and an air pump 33. The air pump 33 is located in the accommodating chamber 12. The input end of the air inlet pipe 31 is connected to the water storage chamber 11. The output end of the air inlet pipe 31 is connected to the input end of the air pump 33. The input end of the air outlet pipe 32 is connected to the output end of the air pump 33. The output end of the air outlet pipe 32 is connected to the pressure relief pipe 4.

[0053] The housing 1 has a water storage chamber 11 and a receiving chamber 12. The air pump 33 is located in the receiving chamber 12 and is connected to the housing 1. The input end of the air inlet pipe 31 is connected to the water storage chamber 11. The air pump 33 can draw gas from the receiving chamber 12 through the input end of the air inlet pipe 31, and then discharge the gas into the pressure relief pipe 4 through the output end of the air outlet pipe 32. Then, the gas is discharged into the external environment through the pressure relief pipe 4, thereby generating a large number of small bubbles, which reduces the density of the surrounding water and accelerates the diving speed of the diving device.

[0054] Furthermore, since the first end of the telescopic component 2 is connected to the housing 1 and the second end of the telescopic component 2 is connected to the pressure relief pipe 4, the distance between the pressure relief pipe 4 and the housing 1 can be adjusted by the telescopic component 2, allowing the bubbles generated by the pressure relief pipe 4 to better surround the housing 1. In addition, when the air duct system 3 in the diving device is not in operation, the pressure relief pipe 4 can be retracted by the telescopic component 2, bringing the pressure relief pipe 4 closer to the side of the housing 1, thus preventing the pressure relief pipe 4 from colliding with external objects due to being too far from the housing 1 during the movement of the diving device.

[0055] For example, the accommodating cavity 12 and the water storage cavity 11 are an integral structural component. The integral structural component has a simpler structure and makes the shell 1 more stable, able to withstand greater external pressure, thus improving the stability of the submersible.

[0056] For example, the water storage chamber 11 is connected to the outside. When the air pump 33 in the air duct system 3 discharges the gas in the water storage chamber 11 to the outside of the shell 1 through the air inlet pipe 31 and the air outlet pipe 32, the pressure inside the water storage chamber 11 decreases, while the pressure in the external environment is greater than the pressure inside the water storage chamber 11. Therefore, by opening the pipe connecting the water storage chamber 11 to the outside, water from the external environment can be allowed to enter the water storage chamber 11 more quickly. Thus, on the one hand, the weight of the water storage chamber 11 increases, which increases the overall weight of the submersible, thereby enabling the shell 1 to submerge more quickly and increasing the submersibility rate of the shell 1. On the other hand, by connecting the water storage chamber 11 to the outside, when the air pump 33 draws air from the water storage chamber 11, the relative pressure difference between the water storage chamber 11 and the external environment is reduced. This prevents excessive pressure from the external water on the outer wall of the shell 1 due to insufficient pressure inside the water storage chamber 11, which could cause deformation of the outer wall of the shell 1. It improved the stability of the diving device.

[0057] Optionally, the pressure relief pipe 4 can be made of copper or copper alloys. Copper and copper alloys have excellent corrosion resistance and a certain degree of strength and hardness, which can improve the service life of the pressure relief pipe 4 and the reliability of the submersion device.

[0058] Optionally, the diameter of the pressure relief hole 41 can be set to 0.5 mm. The smaller diameter of the pressure relief hole 41 results in a greater number of pressure relief holes 41 distributed on the wall of the pressure relief pipe 4, which in turn generates a greater number of small bubbles after the gas enters the water through the pressure relief pipe 4.

[0059] Figure 2 This is a side view of the submersible, combined with... Figure 1 and Figure 2 In this embodiment, the submersible device includes two pressure relief pipes 4, the length direction of which is consistent with the length direction of the shell 1. The air outlet pipe 32 includes a first section pipe 321 and a second section pipe 322. The input end of the first section pipe 321 is connected to the output end of the air pump 33, the output end of the first section pipe 321 is connected to the middle of the second section pipe 322, one output end of the second section pipe 322 is connected to one pressure relief pipe 4, and the other output end of the second section pipe 322 is connected to another pressure relief pipe 4.

[0060] Since the length direction of both pressure relief pipes 4 is consistent with the length direction of the shell 1, the large number of small bubbles discharged from the multiple pressure relief holes 41 in the pressure relief pipes 4 can be more distributed along the length direction of the shell 1, so that a large number of small bubbles are more comprehensively distributed around the shell 1, thereby further reducing the buoyancy of the water around the shell 1 and increasing the diving speed of the shell 1.

[0061] After the air pump 33 introduces gas into the air outlet pipe 32, the gas enters the second pipe 322 via the first pipe section 321. The output end of the first pipe section 321 is connected to the middle of the second pipe section 322, allowing both output ends of the second pipe section 322 to simultaneously supply gas to the two pressure relief pipes 4. This causes the two pressure relief pipes 4 to simultaneously generate a large number of small bubbles, which are distributed around the shell 1, ensuring that the buoyancy of the water around the shell 1 is nearly uniform. This avoids uneven buoyancy around the shell 1 due to large differences in the distribution of small bubbles, which could cause the shell 1 to tilt and affect the normal operation of the submersible. This improves the stability of the submersible.

[0062] Optionally, the vent pipe 32 can be made of rubber, which has the characteristics of high elasticity and non-conductivity. High elasticity allows the vent pipe 32 to move with the telescopic component 2, while non-conductivity helps improve the safety of the submersible in water.

[0063] See you again Figure 1 In this embodiment, the first section of pipe 321 is a retractable spiral-shaped rubber tube.

[0064] Designing the first section of pipe 321 as a retractable spiral shape serves two purposes. First, it allows for stable, synchronized displacement of the first section of pipe 321 during the extension and retraction of the telescopic component 2, with a wide range of movement. Second, when the first section of pipe 321 is in its initial, unstretched state, it maintains high compactness, improving the space utilization of the submersible device. It also effectively prevents the first section of pipe 321 from entangled with the pressure relief pipe 4 or the telescopic component 2, thus ensuring the normal operation of the submersible device and enhancing its reliability. Furthermore, the first section of pipe 321 is made of rubber, which possesses excellent wear resistance and cold resistance, beneficial for underwater operation. Additionally, rubber is less prone to air leakage, further enhancing the stability of the first section of pipe 321.

[0065] See also Figure 1 In this embodiment, the housing 1 has a partition 13 inside, and the outer edge of the partition 13 is connected to the inner wall of the housing 1 to divide the housing 1 into a water storage chamber 11 and a receiving chamber 12. The input end of the air inlet pipe 31 is inserted into the partition 13 at a position away from the telescopic component 2.

[0066] Because the outer edge of the partition 13 is connected to the inner wall of the shell 1, the shell 1 is effectively divided into two non-communicating parts: the water storage chamber 11 and the accommodating chamber 12, which do not affect each other. The water storage chamber 11 not only provides the gas needed for the pressure relief pipe 4 to generate a large number of small bubbles, but also connects to the outside. By introducing a large amount of water, the weight of the water storage chamber 11 is increased, causing the shell 1 to descend rapidly. During the operation of the submersion device, the telescopic component 2 is located below the shell 1, and the input end of the air inlet pipe 31 is inserted into the partition 13 at a position away from the telescopic component 2. That is, the air inlet pipe 31 is located near the top of the shell 1, which helps to keep the input end of the air inlet pipe 31 away from the water surface in the water storage chamber 11, ensuring that the air pump 33 outputs gas from the water storage chamber 11, rather than liquid. In this way, on the one hand, the pressure relief pipe 4 can stably output a large number of small bubbles, and on the other hand, the air pump 33 can operate stably, improving the stability of the submersion device.

[0067] Optionally, the partition 13 can be made of metal such as steel. Steel has high hardness and strength, can withstand strong forces without deformation, which is beneficial to the normal use of the water storage chamber 11 and improves the stability of the shell 1.

[0068] Figure 3 This is a schematic diagram of the pressure relief pipe, combined with... Figure 2 and Figure 3 In this embodiment, the outer wall of the pressure relief pipe 4 has a connector 42, one end of which faces the housing 1 and is connected to the vent pipe 32.

[0069] Because the outer wall of the pressure relief pipe 4 has a connector 42, which is located at the end of the pressure relief pipe 4 near the water storage chamber 11, with one end of the connector 42 facing the shell 1 and the other end connected to the outer wall of the pressure relief pipe 4, the connection between the vent pipe 32 and the connector 42 is more convenient, and to a certain extent, the total length of the air guide pipe system 3 between the water storage chamber 11 and the pressure relief pipe 4 is shortened. The connector 42 is connected to the vent pipe 32, making the connection between the vent pipe 32 and the pressure relief pipe 4 tighter. Through the connector 42, the compressed gas discharged through the vent pipe 32 can stably enter the pressure relief pipe 4, and then form a large number of small bubbles through the pressure relief hole 41 on the pressure relief pipe 4, which are then discharged into the water.

[0070] For example, the outer peripheral wall of the connector 42 is cylindrical and is interference-fitted with the inner peripheral wall of the vent pipe 32. The interference fit makes the connection between the connector 42 and the vent pipe 32 tighter, making it less likely for air leakage or loosening to occur at the connection.

[0071] Figure 4 This is a structural diagram of the telescopic component, combined with... Figure 2 and Figure 4 In this embodiment, the telescopic assembly 2 includes a telescopic cylinder 21, a scissor mechanism 22, and a straight plate 23. The telescopic direction of the telescopic cylinder 21 is consistent with the telescopic direction of the scissor mechanism 22. The cylinder body of the telescopic cylinder 21 is connected to the straight plate 23. The first end of the scissor mechanism 22 is connected to the straight plate 23. The second end of the scissor mechanism 22 is connected to the pressure relief pipe 4. The portion between the first end and the second end of the scissor mechanism 22 is connected to the piston rod of the telescopic cylinder 21. The straight plate 23 is connected to the outer wall of the housing 1.

[0072] Since the straight plate 23 is connected to the outer wall of the housing 1, the housing 1 serves to fix and support the straight plate 23. By connecting the cylinder body of the telescopic cylinder 21 and the first end of the scissor mechanism 22 to the straight plate 23, one end of the telescopic cylinder 21 and the scissor mechanism 22 can be fixed, thereby maintaining stability during operation.

[0073] Since the extension and retraction direction of the telescopic cylinder 21 is the same as that of the scissor mechanism 22, and the portion between the first and second ends of the scissor mechanism 22 is connected to the piston rod of the telescopic cylinder 21, the piston rod of the telescopic cylinder 21 can drive the portion located between the first and second ends of the scissor mechanism 22 to move back and forth during the reciprocating motion of the telescopic cylinder 21. This extension and retraction of the piston rod driven by the cylinder body in the telescopic cylinder 21 then pushes the scissor-type support frame in the scissor mechanism 22 to unfold and fold. Furthermore, since the second end of the scissor mechanism 22 is connected to the pressure relief pipe 4, the scissor mechanism 22 can drive the pressure relief pipe 4 to reciprocate, completing the extension and retraction of the pressure relief pipe 4.

[0074] For example, the scissor mechanism 22 has the advantages of simple structure, small size, light weight, fast operation speed and convenient maintenance.

[0075] See you again Figure 4 In this embodiment, the straight plate 23 has a guide hole 231, which is elongated and the length direction of the guide hole 231 is consistent with the extension and retraction direction of the scissor mechanism 22. The telescopic component 2 includes a guide rod 24, which passes through the piston rod of the scissor mechanism 22 and the telescopic cylinder 21, and is movably inserted into the guide hole 231.

[0076] Since the telescopic assembly 2 includes a guide rod 24, and the guide rod 24 passes through the piston rod of the scissor mechanism 22 and the telescopic cylinder 21, the reciprocating motion of the piston rod in the telescopic cylinder 21 drives the scissor mechanism 22 to move along the direction of the piston rod. Furthermore, since the guide hole 231 is elongated and the guide rod 24 is movably inserted into the guide hole 231, and the length direction of the guide hole 231 is consistent with the telescopic direction of the scissor mechanism 22, the scissor mechanism 22 can effectively move along the length direction of the guide hole 231, and the movement of the scissor mechanism 22 is more stable.

[0077] For example, the diameters at both ends of the guide rod 24 are larger than the diameter at the middle of the guide rod 24. This ensures that the scissor mechanism 22, the telescopic cylinder 21, and the straight plate 23 will not detach from the guide rod 24 due to wear or loosening at the connection points, thus improving the reliability of the telescopic assembly 2.

[0078] See also Figure 4 In this embodiment, the telescopic component 2 includes a positioning rod 25, which passes through the cylinder body of the scissor mechanism 22 and the telescopic cylinder 21, and is connected to the straight plate 23.

[0079] Because the positioning rod 25 passes through the cylinder body of the scissor mechanism 22 and the telescopic cylinder 21, and is connected to the straight plate 23, the connection between the scissor mechanism 22, the telescopic cylinder 21, and the straight plate 23 is more secure and less prone to loosening. This ensures the stability of the telescopic assembly 2.

[0080] For example, the diameters of the two ends of the positioning rod 25 are larger than the diameter of the middle part of the positioning rod 25. This ensures that the scissor mechanism 22, the telescopic cylinder 21, and the straight plate 23 will not detach from the positioning rod 25 due to wear or loosening at the connection points, thus improving the reliability of the telescopic assembly 2.

[0081] See also Figure 4 In this embodiment, the diving device includes at least two sets of telescopic components 2, and each telescopic component 2 is arranged at intervals along the length direction of the shell 1.

[0082] Since the submersible includes at least two sets of telescopic components 2, each telescopic component 2 is arranged at intervals along the length direction of the shell 1, and the length direction of the pressure relief pipe 4 is consistent with the length direction of the shell 1, the arrangement direction of each telescopic component 2 is consistent with the length direction of the pressure relief pipe 4. One end of one set of telescopic components 2 is connected to one end of a pressure relief pipe 4, and one end of the other set of telescopic components 2 is connected to the other end of the pressure relief pipe 4, thereby enabling the telescopic components 2 to stably drive the pressure relief pipe 4 to extend and retract along the length direction of the telescopic components 2.

[0083] For example, combined Figure 1 and Figure 2 The submersible has four sets of telescopic components 2. Two sets of telescopic components 2 are located on one side of the first section of pipe 321 and are connected to both ends of a pressure relief pipe 4, respectively. The other two sets of telescopic components 2 are located on the other side of the first section of pipe 321 and are connected to both ends of another pressure relief pipe 4, respectively. This allows the two pressure relief pipes 4 to be located on both sides of the first section of pipe 321, and the small air bubbles discharged through the pressure relief pipes 4 can more comprehensively cover the outer surface of the shell 1, effectively reducing the density of the water around the shell 1 and increasing the submersible speed.

[0084] See you again Figure 1 In this embodiment, the shell 1 is spindle-shaped, and the outer walls at both ends of the shell 1 are arc-shaped.

[0085] Designing the shell 1 as a spindle shape helps to reduce water resistance during descent. It also increases the water flow rate along the outer wall of the shell 1 during operation, further reducing water resistance during descent. Furthermore, making the outer walls of the shell 1 rounded at both ends further reduces water resistance during descent, increasing the descent speed of the shell 1 in the water.

[0086] For example, the water storage chamber 11 is located at the smaller end of the shell 1, and the receiving chamber 12 is located at the larger end of the shell 1. During the operation of the submersible, water from the external environment enters the water storage chamber 11, increasing its weight. As a result, during submersion, the water storage chamber 11 will be located at the lower end of the water body relative to the receiving chamber 12, thereby enabling the water storage chamber 11 to break through the water body more effectively and accelerate the submersion rate of the shell 1.

[0087] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
