Description

Technical Field

[0001] This invention belongs to the field of underwater communication equipment, and specifically relates to a deep-sea exploration sealed cabin and its underwater acoustic communication equipment. Background Technology

[0002] A deep-sea exploration sealed chamber is a specially designed enclosure used for scientific research, resource exploration, and subsea engineering activities in deep-water environments. The chamber needs to possess excellent sealing performance to withstand water pressure and protect the contents. Underwater acoustic communication equipment is one of the essential components of the deep-sea exploration sealed chamber, used for communication in the underwater environment. Because underwater sound travels at high speeds and attenuates relatively little in water, underwater acoustic communication has become one of the most commonly used communication methods in deep-water environments.

[0003] In existing patent literature, there is a patent with publication number CN 213817794 U and patent name "Sealed Cabin and Underwater Acoustic Communication Device". In this patent, the two ends of the main body (i.e., the sealed cabin) are mainly disassembled and fixed by bolts. Since the sealed cabin is in a deep water environment for a long time, especially in seawater, the threads on the bolts are prone to corrosion, which can easily lead to the main body being unable to be disassembled, making it difficult to maintain or repair later.

[0004] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking excellence, and with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this invention was created to provide a deep-sea exploration sealed cabin and its underwater acoustic communication equipment to solve the above-mentioned problems. Summary of the Invention

[0005] This invention proposes a deep-sea exploration sealed cabin and its underwater acoustic communication equipment, which solves the problems in the prior art.

[0006] The technical solution of this invention is implemented as follows: A deep-sea exploration sealing chamber includes a main sealing chamber and side sealing chambers. The side sealing chambers are detachably fixed to both ends of the main sealing chamber. The main sealing chamber and the side sealing chambers are assembled and fixed together by bolts and nuts. An outer sealing shell is slidably connected to the outer wall of the side sealing chamber. At least one insertion hole is opened at the end of the outer sealing shell. The same number of pins as the insertion holes are movably installed on the outer wall of the main sealing chamber. A spring is fitted on the pins to push them to assemble with the insertion holes. After the pins are assembled with the insertion holes, the outer sealing shell can seal all the bolts and nuts.

[0007] With this design, the deep-sea exploration sealed chamber, by setting an outer sealing shell, can effectively isolate water from bolts and nuts when the exploration sealed chamber is in deep water, thereby preventing seawater from corroding the bolts and nuts, and making it easier to disassemble the internal underwater acoustic communication equipment during subsequent maintenance or repair.

[0008] As a preferred embodiment of a deep-sea exploration sealed chamber, a plug is fixedly connected to the end of the outer sealing shell, and a socket is opened on the plug. An L-shaped base corresponding to the position of the plug is fixedly connected to the outer wall of the main sealing chamber. A pin is slidably installed on the L-shaped base, and a spring pushes the pin into the socket through the base.

[0009] With this solution, the outer sealing shell is positioned mainly by the cooperation of the pin and the hole. Although the pin and the spring are both in deep water, there are no threads on their surfaces. Even if the surfaces are corroded, they can still be disassembled and assembled.

[0010] As a preferred embodiment of a deep-sea exploration sealed chamber, a sealing gasket is provided at the connection between the main sealed chamber and the side sealed chamber, and a sealing gasket is also fixed on the contact surface between the outer sealing shell and the side sealed chamber and the main sealed chamber.

[0011] In order to further improve the sealing performance, this solution uses gaskets to enhance the sealing performance of the connection between the main sealing chamber and the side sealing chamber, as well as the connection between the outer sealing shell.

[0012] As a preferred embodiment of a deep-sea exploration sealed chamber, an anti-interference rotary cylinder is rotatably installed on the outer wall of the main sealed chamber, and the outer wall of the anti-interference rotary cylinder is covered with a conical spike.

[0013] In order to reduce interference from deep-sea organisms, this solution uses a rotating anti-interference cylinder with a cone-shaped spike to prevent organisms from approaching.

[0014] As a preferred embodiment of a deep-sea exploration sealed chamber, rotating fan blades are also fixedly connected to both ends of the anti-interference rotary cylinder, and the length of the rotating fan blades is less than or equal to the length of the cone-shaped part.

[0015] In this design, in order to enable the anti-interference vortex to flow with the deep water, a rotating fan blade is installed to assist the anti-interference vortex in rotating automatically. Since the length of the rotating fan blade is less than or equal to the length of the cone, it is less likely to be damaged.

[0016] As a preferred embodiment of a deep-sea exploration sealed chamber, the inner chamber of the main sealed chamber and the inner chamber of the side sealed chamber are interconnected, and the side sealed chamber has an external opening at the end away from the main sealed chamber.

[0017] By adopting this approach and setting up external openings, communication equipment located inside the deep-sea exploration sealed chamber can better transmit, transmit, or receive signals.

[0018] As a preferred embodiment of a deep-sea exploration sealed cabin, multiple evenly distributed anti-interference fences are fixedly connected around the location of the external opening.

[0019] In order to prevent deep-sea organisms from disturbing the external opening, this solution involves setting up an anti-interference fence to keep the organisms away.

[0020] As a preferred embodiment of a deep-sea exploration sealed cabin, the anti-interference fence is further fixed and connected by annular reinforcing ribs.

[0021] In order to improve the fixing effect of the anti-interference fence, this solution is adopted to strengthen the anti-interference fence by setting ring reinforcing ribs, so as to ensure its reliability during application.

[0022] An underwater acoustic communication device is provided. Based on a deep-water exploration sealed chamber, a communication unit is installed in the main sealed chamber, and transducers and sensors are respectively installed in the side sealed chambers located at both ends of the main sealed chamber. The communication unit is electrically connected to the transducers and sensors via lines.

[0023] Using this scheme, the communication unit includes a central processing module, a communication module, a positioning module, and a power supply module. The communication unit supplies power to the transducer and sensor respectively and transmits communication signals, thereby completing the tasks of communication transmission, transmission, and reception in deep water.

[0024] In a preferred embodiment of an underwater acoustic communication device, inner retaining rings are fixed to both sides of the communication unit and one side of each transducer and sensor. The inner retaining rings have a ring edge array on their sidewalls, and screws are mounted on the ring edge. The end of the screw can abut against the inner wall of the main sealing chamber or the side sealing chamber.

[0025] In order to improve the fixing effect of the communication unit, transducer and sensor, this scheme is adopted. An inner retaining ring is set for tightening. During tightening, the inner retaining ring is fixed to the main sealing chamber or side sealing chamber by rotating the screw.

[0026] After adopting the above technical solution, the beneficial effects of the present invention are: 1. The deep-water exploration sealed chamber, by setting an outer sealing shell, can effectively isolate the bolts and nuts from the water when the exploration sealed chamber is in deep water, thereby avoiding seawater corrosion of the bolts and nuts, and making it easier to disassemble when maintaining or repairing the underwater acoustic communication equipment inside. The outer sealing shell is mainly positioned by the cooperation of the pin and the hole. Although the pin and the spring are both in deep water, there are no threads on their surfaces, so even if the surfaces are corroded, they can still be disassembled and assembled.

[0027] 2. To reduce interference from deep-water organisms, a rotating anti-interference cylinder is installed, which uses a spike to prevent organisms from approaching. To enable the anti-interference cylinder to move with the deep water flow, a rotating fan blade is installed to assist in the automatic rotation of the anti-interference cylinder. The length of the rotating fan blade is less than or equal to the length of the spike, so it is less likely to be damaged.

[0028] 3. To prevent interference from deep-sea organisms at the external opening location, an anti-interference fence is installed to avoid the organisms from approaching. To improve the fixation effect of the anti-interference fence, ring-shaped reinforcing ribs are installed to strengthen the anti-interference fence and ensure its reliability during application.

[0029] 4. In order to improve the fixing effect of the communication unit, transducer and sensor in the underwater acoustic communication equipment, an inner retaining ring is set for tightening. During tightening, the inner retaining ring is fixed to the main sealing chamber or side sealing chamber by rotating the screw. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figures 1 to 5 As shown, a deep-sea exploration sealed chamber includes a main sealed chamber 1 and a side sealed chamber 2. The side sealed chamber 2 is detachably fixed to both ends of the main sealed chamber 1. The main sealed chamber 1 and the side sealed chamber 2 are assembled and fixed by bolts 3 and nuts 4. An outer sealing shell 5 is slidably connected to the outer side wall of the side sealed chamber 2. Two insertion holes 6 are opened at the end of the outer sealing shell 5. The same number of pins 7 as the insertion holes 6 are movably installed on the outer side wall of the main sealed chamber 1. A spring 8 is fitted on the pin 7 to push it to assemble with the insertion hole 6. After the pin 7 is assembled with the insertion hole 6, the outer sealing shell 5 can completely seal the bolts 3 and nuts 4.

[0034] like Figures 4 to 5 As shown, a plug 9 is fixedly connected to the end of the outer sealing shell 5, and a socket 6 is opened on the plug 9. An L-shaped base 10 corresponding to the position of the plug 9 is fixedly connected to the outer wall of the main sealing chamber 1. The pin 7 is slidably installed on the L-shaped base 10, and the spring 8 pushes the pin 7 into the socket 6 by abutting the base.

[0040] like Figure 6 As shown, the anti-interference fence 16 is further fixedly connected by the annular reinforcing rib 17.

[0041] The working principle of this deep-sea exploration sealed cabin: In application, after the main sealing chamber 1 and the side sealing chamber 2 are connected, the main sealing chamber 1 and the side sealing chamber 2 are assembled and fixed by bolts 3 and nuts 4. By sliding the outer sealing shell 5, the pin 7 is pushed by the elasticity of the spring 8.

The communication unit 18 supplies power to the transducer 19 and the sensor 20, and transmits communication signals, thereby completing communication transmission, reception, and other tasks in deep water. To improve the fixation of the communication unit 18, transducer 19, and sensor 20, an inner retaining ring 22 is used for tightening. During tightening, the inner retaining ring 22 is fixed to the main sealing chamber 1 or the side sealing chamber 2 by rotating the screw 24.
