Embodiment Construction

[0089] exist figure 2 A smoke detection center 10 according to the invention is schematically shown in . The smoke detection center 10 has a housing ( )4. A smoke detector, not shown, is installed in the housing 4 . The housing 4 has an inlet 11 . Each inlet port 11 is connected to the three-way valve 1 via a suction hose 3 . Each three-way valve 1 utilizes a connection to pass the CO 2 Manifold and CO 2 The accumulator 8 is connected, and is connected with the fire extinguishing pipe 14 by another interface.

[0090] The fire extinguishing pipeline 14 is connected with the three-way valves 1 that are respectively connected with the warehouses 12 , 13 , 17 , and 18 . exist figure 2 No signal or electrical leads are shown. The housing 4 of the smoke detection center 10 also has an outlet 5 connected to the ventilation unit 6 through a steel pipe 7 . The ventilation unit 6 extracts the sample gas from the cargo chambers 12 , 13 , 17 , 18 and conveys it into the hous...

Abstract

The invention relates to a smoke detection unit (10) with a housing, especially used on ships to detect smoke in sample gas. The unit comprises a smoke detection device integrated in the housing, at least an inlet for the sample gas, devices (5,7) connected with an aspirator (6) used for the sample gas, and/or the aspirator for the sample gas, and a signal output end (2). The smoke detection unit is simple in installation, small in space occupation, and can be preferably integrated in a shipborne monitoring system. The smoke detection unit has an additional singal connection device, used to electrically connect with at least a detection device arranged in a remote manner and preferably electrically connect with data lines of other smoke detection devices, and at least a communication and analysis unit used to communicate with the remote detection device through a signal connection device, or the smoke detection device is provided with a dust filter and/or a sample room is provided with a device used for air flow monitoring.

Description

technical field [0001] The invention relates to a smoke detection unit with a housing, in particular used on a ship, for detecting smoke in a sample gas, the smoke detection unit comprising: at least one smoke detection device integrated in the housing; at least one An input port for the sample gas; a device connected to the sample gas suction device and / or a suction device for the sample gas; and a signal output element. [0002] The invention also relates to a smoke detection system for redundant monitoring of a cargo hold on a ship, the smoke detection system comprising: at least one smoke detection unit according to the preamble of claim 1; at least one suction device , for delivering sample gas from the individual silos to the smoke detection unit; and at least a quantity selected according to the number of silos to be monitored, arranged in each silo, preferably in the ventilation duct, with data The wire detection device is preferably a smoke detection device.
