Detailed Description
The invention is further described with reference to the accompanying drawings and specific embodiments.
In this embodiment, as shown in fig. 1 and 3, the underwater air supply control device includes: two gas cylinders 1, a gas supply pipeline 3 and two control boxes 6.
In this embodiment, one path of the air supply line 3 communicates with the air cylinder valve 3 of one air cylinder 3 and the air inlet connector 601 of one control box 3, and the other path communicates with the air cylinder valve 3 of the other air cylinder 3 and the air inlet connector 601 of the other control box 3, and the two paths of air lines are communicated through two three-way connectors. The place where the gas supply line 3 needs to be bent according to actual needs is realized by a completion 5.
The number of the gas cylinders 2 and the number of the control boxes 6 can be set according to actual needs, one gas cylinder 2 can correspond to a plurality of control boxes 6, a plurality of gas cylinders 2 can also correspond to one control box 6, and the two numbers do not need to be the same. The air supply line 3 may communicate the cylinder valve 3 of the air cylinder 2 with the air inlet end of the air inlet joint 601 of the control box 6 as needed.
As shown in fig. 2 and 3, the control box 6 in the present embodiment includes: an air inlet connector 601, a high-pressure air supply pipeline 602, an inflation valve 603, a stop valve 604, two pressure reducing valves, a two-way medium-pressure air supply pipeline 606, four air supply connectors and two emergency respirators 610.
In this embodiment, the two pressure reducing valves are a breather pressure reducing valve 607 and an emergency breather pressure reducing valve 608. Two of the four air supply connectors are respirator quick connectors 612, and the other two air supply connectors are dry clothing air supply connectors 609.
The air outlet end of the air inlet joint 601 is connected with one end of the high-pressure air supply pipeline 602. The high-pressure air supply line 602 is connected to the air inlet ends of the respirator pressure reducing valve 607 and the emergency respirator pressure reducing valve 608, respectively. A shut-off valve 604 is provided on the high-pressure gas supply line 602. The air outlet end of the respirator pressure reducing valve 607 is connected and communicated with two respirator quick connectors 612 through a middle-pressure air supply pipeline 606. The air outlet end of the emergency respirator pressure reducing valve 608 is connected and communicated with a dry suit air supply connector 609 through another medium-pressure air supply pipeline 606. Two emergency respirators 610 are also connected and communicated with the air outlet end of the emergency respirator pressure reducing valve 608 through another medium-pressure air supply pipeline 606.
The charge valve 603 is disposed on the high pressure air supply line 602 between the inlet connector 601 and the stop valve 604. When the gas quantity in the gas cylinder 1 is insufficient, the stop valve 604 is closed, the gas charging device can reversely charge gas into the gas cylinder 1 through the gas charging valve 603 and the gas inlet connector 601, the gas cylinder 1 does not need to be detached for gas charging, and then the gas charging device is installed, so that the process of replacing the gas cylinder 1 is reduced.
In this embodiment, the control box 6 further includes a pressure gauge 607; the pressure gauge 607 is connected to the high pressure gas supply line 605 to indicate the gas pressure in the area.
In this embodiment, the underwater air supply control device can supply the high-pressure air in the two air cylinders 1 to the two control boxes 6 through the pipeline at the same time, and then the respirator pressure reducing valve 607 and the emergency respirator pressure reducing valve 608 in the control boxes 6 reduce the pressure to a suitable pressure to be supplied to the four sets of scuba diving equipment, the four emergency respirators 610, and the four sets of dry diving suits for use.
The working principle of the underwater air supply control device is as follows:
the underwater gas supply control device is arranged on an underwater conveying boat, when the underwater gas supply control device is used, a respirator quick-connection plug on the underwater gas supply control device is connected with a diving respirator, two gas bottle valves of the underwater gas supply control device are opened, gas enters two control boxes through pipelines, after entering the control boxes, two paths are divided into each control box, and after one path is decompressed to proper pressure through a respirator pressure reducing valve in the control boxes, two paths are divided for 2 sets of diving breathing apparatus on the underwater conveying boat; and the other path is divided into four paths after passing through an emergency respirator pressure reducing valve, wherein two paths are connected with 2 sets of emergency respirators and used for breathing by using the emergency respirators when the scuba diving apparatus of a diver breaks down or has an accident, and the other two paths are connected with a dry-type diving suit inflation joint and used for inflating the dry-type diving suit after being connected with the dry-type diving suit when the diver wears the dry-type diving suit underwater. When a diver takes the underwater conveying boat to arrive at a preset place and needs to leave the conveying boat for operation, the quick-connection-peg of the respirator can be separated from the scuba, and the diver can use the self-carrying gas cylinder carried by the scuba to breathe.
After the underwater gas supply control device is adopted, a diver can breathe gas in a gas cylinder of the underwater gas supply device when the diver is on an underwater conveying boat, and the diver can breathe the gas in the gas cylinder of the underwater gas supply device only when the diver needs to leave the underwater conveying boat for operation, so that the underwater life support time of the diver can be greatly prolonged.
The underwater air supply control device also provides an emergency respirator, so that emergency breathing can be provided for a diver when the diver respirator breaks down, and the underwater safety of the diver is improved.
The underwater air supply control device is provided with the air inflation interface of the dry-type diving suit, and can inflate the dry-type diving suit worn by a diver, thereby avoiding the problem that the air in the self-carrying air bottle is used for inflating the dry-type diving suit, and the air quantity is not enough.
