Problems solved by technology

The installation method of the bottom-connected escape cabin in the lifeboat, the docking interface of the escape cabin, the fixed back plate, and the fixing bolts all protrude from the bottom of the boat, which will increase the huge resistance of the hull when the lifeboat is sailing, resulting in the need to match high-power The main engine (usually 140 horsepower) and a large-capacity fuel tank are used to achieve a speed of not less than 6 knots and a 72-hour endurance time, which also greatly increases the weight of the entire boat, increases the draft of the boat, and in turn increases the resistance of the boat
In addition, the bottom fixing bolts penetrate the bottom of the boat and protrude out of the boat. If there is a collision with the mother ship when the boat is lowered, it may cause water to enter the boat and cause the lifeboat to capsize; The bottom keel, which plays a decisive role in the overall longitudinal strength of the lifeboat, has to be disconnected in many places, which also reduces the overall strength of the lifeboat
[0005] In the existing saturation diving operation, the lifeboat is docked with the channel of the mother ship at the bottom of the boat. When the decompressed diver escapes, because of wearing diving equipment, he still needs to climb to the escape cabin when his physical strength drops. It greatly affects the escape efficiency. In addition, there is still the problem that the escape cabin cannot implement rapid self-rescue escape without power. Further improvements to the existing escape boat structure are required.

Embodiment Construction

[0029] combine Figure 1 to Figure 6 As shown, the specific implementation of a side-mounted high-pressure escape boat provided by the present invention will be described.

[0030] A side-connected high-pressure escape boat, which is used in the emergency evacuation of divers during the decompression process. It integrates the side-connected escape cabin into the escape boat. The escape cabin has self-propelled capability, and the hull 1 is made of fire-resistant glass fiber reinforced plastic. Manufactured and equipped with other fire safety measures to facilitate the safe and rapid evacuation of divers who are decompressing.

[0031] The specific structure of the side-connected high-pressure escape boat is that a side-connected high-pressure escape cabin is installed in the hull 1 of the escape boat. The bow in the length direction is the front, the stern is the rear, and the length direction of the hull is the direction between the bow and the stern. The side-connected hi...

Abstract

The invention provides a side connection type high-pressure escape boat, and relates to the technical field of saturated diving safety lifesaving equipment. A side connection type high-pressure escapecabin is installed on the middle front portion in a boat body of the escape boat and comprises a cabin body, a side support, a base and a lateral butt joint opening, the support and the base are fixedly connected with the boat body, the lateral butt joint opening extends to the boat body, and the lateral butt joint opening of the high-pressure escape cabin is fixedly connected with the boat bodythrough a connecting flange. The lateral butt joint opening of the high-pressure escape cabin is connected with the pressure reduction cabin of a mother ship through an escape channel, and the high-pressure escape cabin and the escape channel are fixed in a detachable mode. The side connection type high-pressure escape cabin is of an asymmetric structure and is transversely and eccentrically installed in the boat. The lateral butt joint opening and the boat body are installed in a concave mode, and the lateral butt-joint opening is integrally arranged in the boat body and can be of a circularhorn mouth structure. The side connection type high-pressure escape boat provides an emergency escape path for a diver who is decompressing in saturated diving operation, and the self-rescue capacityof the escape boat is improved.

Description

technical field [0001] The invention relates to the technical field of safety and lifesaving equipment for saturation diving, in particular to a side-connected high-pressure escape boat. Background technique [0002] In the field of saturation diving, divers need to dive to a certain depth (usually 200m to 300m) underwater to work. Due to the large pressure difference between the underwater and the surface, the diver needs to go through a long decompression process after returning to the sea surface, otherwise it will cause serious injury to the diver's body. This process is generally equipped on the diving work mother ship in a decompression chamber. Once an emergency occurs on the mother ship, just as the crew of a conventional ship needs to be equipped with life-saving equipment to escape, the divers who are decompressing the decompression chamber also need a special emergency evacuation system to escape. [0003] At present, the common high-pressure evacuation devices ...
