Description

Technical Field

[0001] This utility model relates to the technical field of sealed chambers, and in particular to a sealed chamber for deep-sea environment training. Background Technology

[0002] With the deepening of global marine development strategies, the iterative development of deep-sea resource exploration, scientific research, and diving equipment technology has placed higher demands on extreme environment simulation equipment. Deep-sea environment training chambers, as the core carrier for constructing high-pressure, low-temperature, and highly corrosive composite working conditions, are gradually becoming an important support for breakthroughs in marine engineering technology. In the field of marine resource exploration, this equipment can construct simulated seawater environments with complex compositions, providing a full-lifecycle reliability testing scenario for deep-sea oil and gas extraction devices and seabed mineral exploration robots. In diver adaptation training scenarios, the chamber, through precise control of dynamic pressure gradients and breathing gas ratios, creates a physiological stress environment close to the real deep sea for trainees, effectively enhancing their high-pressure tolerance and reducing occupational health risks such as decompression sickness.

[0003] Traditional deep-sea environment training sealed chambers have inefficient sealing and opening / closing mechanisms that rely on bolt fastening or clamp-type seals. Each opening and closing takes a long time, and uneven bolt stress can easily lead to wear on the sealing surface. Under high pressure, the leakage rate is high, and there is a lack of passive safety designs such as emergency window breaking. In extreme cases, there is a risk of high pressure leakage or personnel being trapped. Utility Model Content

[0004] The purpose of this utility model is to provide a deep-sea environment training sealed chamber to solve the problems mentioned in the background art, such as the low efficiency of the sealing and opening and closing mechanism of the traditional deep-sea environment training sealed chamber, the reliance on bolt fastening or clamp sealing, the long time required for each opening and closing, the uneven force on the bolts which easily leads to wear on the sealing surface, the high leakage rate under high pressure, and the lack of passive safety designs such as emergency window breaking, which poses a risk of high pressure leakage or personnel being trapped in extreme situations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a deep-sea environment training sealed chamber, comprising a base, a sealed chamber fixedly mounted on the upper surface of the base, a sealing cover fixedly mounted on the right end of the sealed chamber, an observation window fixedly mounted on the front end of the sealed chamber, a pressure control machine fixedly mounted on the upper surface of the base, a flange fixedly mounted on the right end of the pressure control machine, an air pipe provided at the front end of the sealed chamber, a water outlet pipe fixedly mounted on the front surface of the sealed chamber, a water inlet pipe fixedly mounted on the front surface of the sealed chamber, a valve sleeved around the outer ring of the water inlet pipe, and a support column provided on the inner side of the sealed chamber.

A spring is sleeved on the outer ring of the connecting rod. A spring tongue is fixedly installed at the front end of the connecting rod. Glass covers are fixedly installed through both ends of the sealing cover. A window breaker hammer is provided at the rear end of the sealing cover.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This deep-sea environment training sealed chamber addresses the problems of low opening and closing efficiency, easy wear of sealing surfaces, and lack of emergency escape devices caused by the reliance on bolt fastening in traditional deep-sea environment training sealed chambers. This design adopts a cam-linkage linkage locking mechanism. By rotating the handle, the cam drives the spring to quickly engage the sealing cover, shortening the opening and closing time of the chamber door. Combined with the pressure self-tightening effect of the fluororubber sealing ring, the high-pressure leakage rate is reduced, completely solving the problem of sealing failure caused by uneven bolt force. At the same time, a tungsten steel window breaker hammer and a polycarbonate organic glass cover are integrated at the rear end of the sealing cover. The former uses a tungsten steel wedge-shaped hammer head with a hardness ≥ HRC68, which can quickly shatter the glass cover in an emergency, forming an escape channel within 30 seconds.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4This utility model provides a technical solution: a deep-sea environment training sealed chamber, including a base 1, a sealed chamber 2 fixedly installed on the upper surface of the base 1, a sealing cover 3 fixedly installed on the right end of the sealed chamber 2, an observation window 4 fixedly installed on the front end of the sealed chamber 2, a pressure control machine 6 fixedly installed on the upper surface of the base 1, a flange 7 fixedly installed on the right end of the pressure control machine 6, an air pipe 8 provided at the front end of the sealed chamber 2, a water outlet pipe 9 fixedly installed on the front surface of the sealed chamber 2, a water inlet pipe 10 fixedly installed on the front surface of the sealed chamber 2, a valve 11 sleeved on the outer ring of the water inlet pipe 10, a support column 12 provided on the inner side of the sealed chamber 2, and a fixing ring 1 fixedly installed on the front surface of the sealing cover 3. 4. A rotating rod 15 is provided on the front surface of the sealing cover 3. A door 16 is provided at the front end of the sealing cover 3. A sealing ring 17 is fixedly installed on the front surface of the sealing cover 3. A connecting block 18 is fixedly installed through both ends of the door 16. A handle 19 is fixedly installed at both ends of the connecting block 18. A cam 20 is sleeved on the outer ring of the connecting block 18. A connecting rod 21 is sleeved on the outer ring of the cam 20. A protective shell 22 is provided on the inner side of the door 16. A connecting rod 23 is fixedly installed at the front end of the connecting rod 21. A spring 24 is sleeved on the outer ring of the connecting rod 23. A spring tongue 25 is fixedly installed at the front end of the connecting rod 23. A glass cover 26 is fixedly installed through both ends of the sealing cover 3. A window breaker hammer 27 is provided at the rear end of the sealing cover 3.

[0020] Furthermore, a pressure sensor 5 is fixedly installed at the upper end of the sealed chamber 2, and the sensing end of the pressure sensor 5 is embedded in the sealed chamber 2. A temperature sensor 13 is set at the front end of the sealed cover 3, and the sensing end of the temperature sensor 13 is embedded in the sealed cover 3. The pressure sensor 5 is a CYH1454606 deep-sea pressure sensor, and the temperature sensor is an OmegaPR-22 Pt100 temperature sensor. The pressure sensor 5 is used to monitor the pressure value inside the sealed chamber 2 in real time, so as to achieve precise control of the pressure inside the chamber and overpressure early warning, and ensure the stability and safety of the deep-sea environment simulation.

[0021] Furthermore, the pressure controller 6 is connected to the air pipe 8 via flange 7, and the sealed chamber 2 is connected to the air pipe 8 via flange 7. The pressure controller 6 is configured as a HYDRA2000 pressure controller, which precisely adjusts the pressure inside the chamber to 10-100MPa to simulate the high-pressure environment of the deep sea.

[0022] Furthermore, the materials of the sealed chamber 2 and the sealed cover 3 are austenitic stainless steel. The sealed chamber 2 provides a closed high-pressure simulation space and forms a complete sealing system with the sealed cover 3 to accommodate diver training or equipment testing.

[0023] Furthermore, the outer ring of the door 16 is fitted with a sealing ring 17, which is made of fluororubber. With the setting of the sealing ring 17, when the door 16 and the sealed chamber 2 are closed, the micro gaps in the contact surface are filled by elastic deformation to form a high-pressure sealing barrier.

[0024] Furthermore, the glass cover 26 is made of polycarbonate plexiglass and has a scratch-resistant coating on its surface. The hammer head of the window breaker 27 is made of tungsten steel. With the setting of the window breaker 27, its tungsten steel hammer head can quickly break the polycarbonate plexiglass cover 26 with a scratch-resistant coating in an emergency, forming an emergency escape route to ensure personnel safety.

[0025] Furthermore, a walkie-talkie 28 is installed at the rear end of the sealing cover 3, and a light 29 is installed at the rear end of the sealing cover 3. The walkie-talkie 28 is modeled as Baofeng UV-28L, and the light 29 is modeled as a convection-cooled LED light. Real-time voice communication between the cabin and the outside is achieved through multi-band radio signals.

[0026] Working Principle: First, the equipment is securely installed on the base 1. An external temperature-controlled water source is connected via the inlet pipe 10. The circulating fluid flow rate is adjusted using valve 11 to preset the chamber water volume. When the chamber door 16 needs to be opened, rotating the handles 19 on both sides drives the cam 20 to rotate, which in turn drives the spring tongue 25 to disengage from the sealing cover 3 via the connecting rod 21. After personnel or testing equipment enter the chamber, the handles are rotated in the opposite direction to close the chamber door. After releasing the handles, the spring 24 pushes the spring tongue to precisely engage with the fixing ring. The automatic locking of the cam-connecting rod mechanism is completed within 5 minutes. Combined with the elastic deformation and pressure self-tightening characteristics of the fluororubber sealing ring 17, a high-pressure sealing barrier is formed, reducing leakage. The pressure control unit 6 injects gas into the chamber through the flange 7 and the air pipe 8. The system simulates deep-sea pressure conditions of 10-100MPa. During this period, pressure sensor 5 and temperature sensor 13 collect data in real time to ensure that the pressure gradient changes required for diving training, such as simulating the dive-stay-decompression process or the constant high-pressure environment required for equipment testing, are stable and controllable. Observation window 4 and built-in lighting 29 provide visual observation conditions inside the cabin. Walkie-talkie 28 enables real-time voice communication between the inside and outside to ensure coordinated operation. In case of emergency such as system failure or abnormal pressure, the tungsten steel window breaker 27 at the rear end of the sealing cover 3 can be used directly. Its wedge-shaped hammer head can break the polycarbonate glass cover 26 with a scratch-resistant coating within 30 seconds to quickly form an emergency escape channel. After the training is completed, the water in the sealed chamber is discharged through the water outlet pipe 9.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
