AI Technical Summary
Traditional smoke detection systems cannot quickly and accurately detect the middle part of the cargo hold and the lower cargo hold area after the middle deck of the large cargo hold, resulting in timely discovery of fire hazards.
By hoisting and installing the movable middle deck, and installing a detachable sampling tube and a pumped sampling head, the sampling head is connected to the smoke detection main pipe by using a connecting hose with a quick joint to achieve smoke detection in the middle and lower areas of the cargo hold.
It realizes precise positioning and detection of the middle part of the cargo hold and the lower part of the middle deck, improves the timely detection of fire hazards and crew safety guarantees, and effectively prevents the occurrence of fire accidents.

Abstract
Description
Technical Field
[0001] The invention relates to a zoning smoke detection method for a ship cargo hold. Background Art
[0002] Smoke detection systems play a very important role on ships. During sea voyages, since ships are usually closed environments, once a fire occurs, the fire spreads very quickly, and the crew's evacuation and escape time is very limited. The smoke detection system can detect smoke and fire in time, help the crew respond quickly, and the alarm system will sound in time to ensure that the crew can escape quickly when a fire occurs. In addition, the smoke detection system can not only help the crew detect the fire in time, but also help the crew accurately locate the source of the fire, which helps to take appropriate fire-fighting measures to prevent the spread of the fire. The installation and use of the smoke detection system not only helps to ensure the life safety of the crew on board, but also protects the property safety of the ship. , to prevent greater losses caused by fire; currently, smoke detection systems are generally equipped on cargo hold hatch covers or hatch enclosures of bulk carriers, general cargo ships and multi-purpose ships that transport flammable goods. They can only detect smoke in the entire cargo hold, but for ships equipped with a large cargo hold movable middle deck, the traditional probe installation position cannot quickly and accurately detect the middle of the cargo hold and the lower cargo hold area after the middle deck is divided. It can only be detected when the smoke has spread to the top of the large cargo hold, and the fire hazard cannot be discovered in time; therefore, for ships with a large cargo hold movable middle deck, gas detection in the middle of the cargo hold and the lower cargo hold area after the middle deck is divided has become a key problem. Summary of the invention
[0003] The purpose of the present invention is to provide a ship cargo hold partition type smoke detection method.
[0004] The technical solution adopted by the present invention to achieve the above-mentioned purpose is: a ship cargo hold partition type smoke detection method, comprising the following steps: Step 1, hoisting the movable middle deck (6) to a suitable position in the cargo hold (7) according to the size or type of cargo carried in the cargo hold (7) on this voyage; Step 2, after the movable middle deck (6) is installed and fixed, a detachable sampling tube (2) is arranged on the upper surface of the movable middle deck (6), and connected with a flange, and the sampling head (1) is arranged at the center of the movable middle deck (6); Step 3, connect one end of the connecting hose (3) with a quick connector to the quick connector at the end of the detachable sampling tube (2), and connect the other end to the quick connector in the hose connector box (4), so that the sampling head (1) is connected to the smoke detection main pipe (5); Step 4, start the smoke detection equipment, take samples from the cargo hold isolated under the movable middle deck (6), and complete the detection.
[0005] In the step 1, the movable middle deck (6) is hoisted to position a, b or c of the cargo hold (7).
[0006] In step 2 and step 3, the sampling head (1) is a vacuum type sampling head.
[0007] In step 3, the smoke detection main pipe (5) is connected to the smoke detection device.
[0008] The present invention provides a ship cargo hold zoning smoke detection method, which can make the cargo hold freely zoned according to the installation position of the middle hatch cover, is more flexible and accurate, can accurately locate smoke and fire, and can ensure timely and accurate detection of smoke in the cargo hold below the middle deck, thereby improving the safety of crew members, discovering fire hazards more timely, effectively preventing the occurrence of fire accidents, and improving the safety of ships.

[0011] like Figure 1As shown, the zoning smoke detection method for a ship cargo hold comprises the following steps: step 1, hoisting the movable middle deck 6 to the appropriate position of the cargo hold 7, position a, b or c, according to the size or type of the cargo carried in the cargo hold 7 of this voyage; step 2, after the movable middle deck 6 is installed and fixed, a detachable sampling tube 2 is arranged on the upper surface of the movable middle deck 6, and connected with a flange, and the sampling head 1 is arranged at the center of the movable middle deck 6, and the sampling head 1 adopts an exhaust type sampling head; step 3, connecting one end of a connecting hose 3 with a quick connector to the quick connector at the end of the detachable sampling tube 2, and connecting the other end to the quick connector in the hose connector box 4, so that the sampling head 1 is connected to the smoke detection main pipe 5, and the sampling head 1 adopts an exhaust type sampling head, and the length of the connecting hose 3 with a quick connector needs to be adjusted according to the position of the hatch cover. Configuration, a hose connector box 4 is used to protect the quick connector when loading bulk cargo, and the smoke detection main pipe 5 is connected to the smoke detection device; step 4, starting the smoke detection device, sampling the cargo hold isolated under the movable middle deck 6, realizing smoke detection in the space divided by the movable middle deck, and completing the detection; the ship cargo hold partitioned smoke detection method of the present invention relates to the field of general cargo ships and multi-purpose ships equipped with a detachable middle deck, and in particular to ships with a cargo hold size greater than 24 meters in length and width and a movable middle deck. By changing the length of the detachable hose, smoke detection of different spaces divided by the movable hatch cover is realized, so that the cargo hold can be freely partitioned according to the installation position of the middle hatch cover, which is more flexible and accurate than the traditional fixed smoke detection system, and at the same time can also ensure the detection distance required by the classification society regulations and the safety of the ship.
