Abstract
The utility model discloses a fire alarm device for an offshore wind power unit. The fire alarm device comprises a fire alarm controller and an air-breathing smoke detector, wherein the air-breathing smoke detector is connected with the fire alarm controller, and the air-breathing smoke detector is arranged in an area needing to be protected. The fire alarm device for the offshore wind power unit is applied to all parts of easily firing of the wind power unit, and is capable of timely sending multistage alarms at the initial stage of the fire and starting the fire alarm controller, thus the firing probability of the offshore wind power unit is greatly reduced; an active air-breathing sampling type is adopted, thus the fire alarm device has higher sensitivity and solves the influence of airflow to smoke detection; and moreover, a capillary sampling pipe stretches into a cabinet for detecting, thus smoke grains can be detected at the initial stage of the fire, and then an extreme early alarm is made for the potential fire.
Description
Technical field
The utility model relates to fire alarm installation, refers in particular to a kind of fire alarm installation for the offshore wind farm unit.
Background technology
Oversea wind power generation has that wind energy resources is abundant, wind speed is high and stable, the advantage such as land occupation, suitable large-scale development not, has great development potentiality.Marine wind electric field is abominable apart from bank distance, running environment, in case the breaking out of fire of offshore wind farm unit will face the risk of burning fully, causes great economic loss, therefore, is very important for offshore wind farm unit automatic fire alarm system.
The offshore wind farm unit partly is comprised of impeller, cabin, pylon etc.The position of the easy breaking out of fire of wind-powered electricity generation unit mainly comprises: generator, hydraulic system, gear case, brake system, yaw system and switch board in (1) cabin; (2) drive motor in the wheel hub, switch board etc.; (3) cable passage, the converter cabinet at the bottom of the tower and the switch board etc. in the pylon.
At present, domestic Its Relevant Technology Standards and the standard of there is no of the automatic fire alarm system of offshore wind farm unit, most wind-powered electricity generation units do not arrange fire automatic alarm device, only in the pylon bottom hand fire extinguisher are set.In case adopt the breaking out of fire of this kind mode, the operations staff can't obtain fire alarm information in the very first time; Owing to there not being fire automatic alarm device, can't realize self-extinguishing, the wind-powered electricity generation unit will face the risk of all burning, and causes great economic loss.
The offshore wind farm units that are provided with automatic fire alarm system few in number only adopt Point-type fire detectors as fire detecting arrangement, and search coverage also only comprises cabin or column foot position.Adopt this kind mode to have following deficiency:
(1) the detection zone is limited, such as cable passage and the wheel hub of pylon sniffer is not set all, can't provide general protection to the wind-powered electricity generation unit;
The reasons such as (2), converter cabinet large owing to Air Flow in the cabin and switch board sealing be strong, the point type detector can't effectively be reported to the police at the fire early period of origination, will miss the preferably opportunity of early stage fire extinguishing, causes larger economic loss.
Summary of the invention
The utility model provides a kind of fire alarm installation for the offshore wind farm unit, and it can overcome the defective of prior art, can be arranged at the zone of a plurality of easy breaking out of fires.
The utility model is achieved in that
A kind of fire alarm installation for the offshore wind farm unit; it includes fire alarm control unit and aspirating smoke detector; described aspirating smoke detector is connected with described fire alarm control unit, and described aspirating smoke detector is arranged in the zone that needs protection.
Preferably, described offshore wind farm unit includes cabin, pylon and wheel hub, and described aspirating smoke detector includes sampling pipe, is provided with a plurality of thieff hatchs on the described sampling pipe, is provided with sampling pipe in described cabin, described pylon and the described wheel hub.
Preferably, be provided with engine room control cabinet and cabin regulator cubicle in the described cabin, described aspirating smoke detector also includes the capillary sampling pipe, and described capillary sampling pipe extend in described engine room control cabinet and the described cabin regulator cubicle.
Preferably, be provided with pylon switch board and pylon regulator cubicle in the described pylon, described air breathing type detection device also is surrounded by the capillary sampling pipe, and described capillary sampling pipe extend in described pylon switch board and the described pylon regulator cubicle.
The fire alarm installation that the utility model is used for the offshore wind farm unit compared with prior art has following beneficial effect:
(1) the utility model detection scope of being used for the fire alarm installation of offshore wind farm unit covers the position of all easy breaking out of fires of wind-powered electricity generation unit, solves in the past the offshore wind farm unit without fire automatic alarm device or the little problem of detection scope.
(2) adopt aspirating smoke detector in time to send Multi-stage alarming in the initial period that fire occurs, start the fire alarm controller, greatly reduce the probability of offshore wind farm unit breaking out of fire, solved the problem that prior art can't effectively be reported to the police at the fire early period of origination.Simultaneously, air suction type formula smoke detector adopts air suction type sample mode initiatively, has very high sensitivity, has successfully solved the impact of air-flow for smoke detection.In addition, adopt the capillary sampling pipe to stretch in the cabinet and survey, can survey smoke particle in the primary stage of fire, thereby the potential condition of a fire is made utmost point early warning
