peninsula all media reporter sun zhaohui li xiaozhe wang chunyan

in the past few days, the northern theater command naval ship open day to celebrate the 75th anniversary of the founding of the people's republic of china has continued to be popular, with an endless stream of citizens and tourists visiting. in addition to boarding the ship to visit, various activities on site also make the trip more lively and interesting. the reporter noticed that there are “special subject display and experience areas” at qingdao port pier 3 and the olympic sailing center. on october 3, reporters came forward to experience wearing fire fighting uniforms, tying knots and making international signals, and experienced the training life of the crew.

reporters put on firefighting suits with the help of crew members

all the equipment weighed more than 30 kilograms, and i was sweating profusely in less than a minute in the combat uniform.

the thick mustard-yellow firefighting suit covered the whole body tightly, put on the helmet and gloves, put down the mask, and sucked on the oxygen bottle. the outside world suddenly became quiet...

"oh my god, it's like a steamer inside. it's so difficult for the crew." lin yuhang, who had just finished wearing a firefighting combat uniform, had sweat stains on his back. what kind of experience is it to wear this thick "big cotton jacket"? the reporter decided to join the experience team.

after taking off his shoes and putting on blue shoe covers, the reporter stepped into calf-high boots. the trouser legs of the combat uniform were already worn over the boots. the several centimeters of thick clothing and stiff boots made it difficult for the feet to move due to their heavy weight.

the crew demonstrated the masthead knot to reporters

sailor yu haoyi continued to help the reporter "increase strength." the moment the oxygen tank weighing more than 20 kilograms was put on the upper body, the reporter felt that his body was falling backwards. after buckling the inner belt, put the respiratory mask, flame retardant mask, and helmet on your head layer by layer. by this time, beads of sweat were already forming on the reporter's forehead. as you lift up your clothes and put them on, your body gradually begins to feel warm, like being in a sauna.

after putting on the respirator, the reporter inhaled hard and heard a "bang" sound as the oxygen tank was opened. at this time, the only sound in the reporter's ears was his own breathing, and the outside world seemed to have clicked the mute button. the crew members usually use walkie-talkies to communicate.

with the assistance of the crew members, this dressing process takes about 4 minutes in total. yu haoyi told reporters that they usually need to control it to about 1 minute when wearing it by themselves.

the whole suit weighed more than 30 kilograms. it was difficult for the reporter to take even two steps. it was hard to imagine how the crew could move quickly with such weight.

after being "closed" for less than a minute, the reporter began to sweat all over his body. it wasn't until i took off my combat uniform and relaxed for a while that the hot feeling subsided. the crew sometimes wore them for hours at a time.

after the reporters, citizens came to experience it. during the repeated putting on and taking off, the sweat on yu haoyi's cheeks fell drop by drop.

making semaphores around the knots, they seemed to be speeding up

the reporter went to the boat art knot display area to experience it, and saw that the knots on display included clove knots, sailor knots, pallet knots, etc. the reporter experienced the simplest clove knot and the most difficult masthead knot respectively.

sailor yang xudong demonstrated the clove knot to reporters first. a rope is placed on the railing and hangs down on both sides. the rope on the back side is pressed on the rope on the front side and looped around the railing. put it into the circle. pull the other rope hard and wrap it tightly around the railing.

it really seems easier than done. when the reporter did it alone, it was completely messed up. yang xudong demonstrated one step, and the reporter did another step, and then the lilac knot was completed.

"if it is a relatively rough rope, like hemp rope, the lilac knot can bear a load of 100 kilograms. the lilac knot is generally used to be fixed on the railings or handrails of ships to lift things. it is simply fixed and easier and faster to operate than other knots." he introduced.

the most complex of the knots shown today is the masthead knot. yang xudong made three loops with the rope, and pulled out three more loops with his movements as fast as a flash. the authentic masthead knot has three loops, one counterclockwise and two clockwise. in order to reduce the difficulty, he and the reporters made three loops counterclockwise, overlapping the loops, and hooking up the three loops with his fingers. corner, masthead knot is done.

"today's ships no longer need a masthead knot. in the past, sailboats did. this masthead knot was used as a pulley." yang xudong introduced.

the international signal semaphores abcd and others all have corresponding gestures. the reporter followed the actions of the crew members. a placed the flag in his left hand between his legs and raised his right hand at 45 degrees. b raised it at 90 degrees until d reached the top of his head. for e, f, and g, the right hand is placed between the legs, and the left hand gradually falls from top to bottom.

"for example, hello, we can use semaphore to express it. this is an essential communication skill for every sailor. the application scenario is to communicate between our ships. this is a relatively guaranteed communication method. in case of special if there is no signal, it can be used after the two ships meet at close range," a crew member told reporters.
