Embodiment 1

[0033] see figure 1, the present invention provides a breathing air supply system for a closed diving bell, comprising a diving bell body 1, an air supply unit 2, a supply unit 3 and an emergency unit 4 communicated with the outside of the diving bell body 1; the air supply unit 2 The breathing mixture is supplied to the diving bell body 1 through the main umbilical cord 5; the supply unit 3 is connected with the diving bell body 1 through pipelines; the diving bell body 1 supplies the breathing mixture gas to the bellman and the diver respectively; the air supply unit 2 and the main umbilical cord 5 A pressure regulation unit A6 is arranged between them, a pressure regulation unit B7 is arranged between the supply unit 3 and the diving bell body 1; a gas concentration analysis unit 8 is arranged between the gas supply unit 2 and the pressure regulation unit A6; the gas concentration analysis unit 8 is used to measure and display the oxygen concentration and carbon dioxide con...

Embodiment 2

[0035] see Figure 2 to Figure 6 , this embodiment refines the system structure on the basis of Embodiment 1, specifically as follows:

[0036] The inside of the diving bell body 1 is provided with a gas delivery pipeline A11 and several gas delivery pipelines B12, the gas delivery pipeline A11 is used to provide the bell person with a breathing mixture, and the gas delivery pipeline B12 is used to provide the diver with a breathing mixture; the gas delivery pipeline A11 Along the direction of gas transmission, it includes the connected equipment air chamber regulator D112 and ball valve E111 in sequence, and the two sides of the equipment air chamber regulator D112 are respectively equipped with pressure gauge D114 and pressure gauge E113; Connected equipment air chamber regulator E123 and ball valve F121, equipped with pressure gauge F122 and pressure gauge G124 on both sides of the equipment air chamber regulator E123 respectively; gas pipeline A11 communicates with main um...

Abstract

The invention relates to the technical field of saturated diving, in particular to a breathing air supply system of a closed diving bell, which comprises a diving bell body, and an air supply unit, a supply unit and an emergency unit are respectively communicated with the outside of the diving bell body; the air supply unit and the supply unit supply breathing mixed air to the diving bell body through a main umbilical cord; the diving bell body supplies breathing mixed air to a bell person and a diver; a pressure regulating unit A is arranged between the air supply unit and the main umbilical cord, and a pressure regulating unit B is arranged between the supply unit and the diving bell body; a gas concentration analysis unit is arranged between the air supply unit and the pressure regulating unit A; when the air supply unit cannot provide the breathing mixed air, the supply unit starts to provide the breathing mixed air; when the main umbilical cord breaks down and cannot convey the breathing mixed air and the supply unit cannot supply the breathing mixed air, the emergency unit starts to supply the breathing mixed gas to the diving bell body; therefore, normal breathing of the diver and the bell person in the diving bell is guaranteed, emergency treatment can be carried out when an accident occurs, and life safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of saturation diving, in particular to a breathing air supply system for a closed diving bell. Background technique [0002] Saturation diving is a diving method suitable for long-term operations at large depths. Saturation diving technology is the only way that allows divers to be directly exposed to underwater high-pressure environments for long-term diving operations, which greatly improves divers' operating efficiency. Therefore, diving technology has shown its importance as an important means of underwater operations. The diving bell is an important equipment for people to engage in underwater activities. A diving bell is a bell-shaped pressure vessel that is equipped on a ship that needs to conduct diving operations, and can transport personnel between the underwater and the deck. Diving bells for diving operations can generally be divided into open diving bells and closed diving bells according to ...
