The specific embodiment
The scheme of installation of the utility model wind-powered electricity generation unit electrical control cubicles fire extinguishing system as shown in Figure 1.Extinguishing chemical storage bottle 2 is connected to an end of conveyance conduit 3 by a controlled valve (Fig. 1 is not shown), and the other end of conveyance conduit 3 feeds in the electrical control cubicles 1, preferably from electrical control cubicles.The benefit that the extinguishing chemical storage bottle is external is that the extinguishing chemical storage bottle can not take space in the cabinet, and is convenient to the maintenance and the replacing of fire extinguishing system.Can control the release of extinguishing chemical in the extinguishing chemical storage bottle 2 by the keying of a control circuit by-pass valve control.
Extinguishing chemical preferably adopts ultra-fine dry powder extinguishing agent, and such extinguishing chemical storage bottle is an existing product, can directly buy from the market.Select ultra-fine dry powder extinguishing agent for use except that being applicable to the electrical fire because of it, other benefit is that the protection thing is not had corrosion, and is nontoxic; This extinguishing chemical is zero to atmospheric ozone layer depletion latent energy value simultaneously, and greenhouse effects subtract that to be worth be zero, to human body skin and non-stimulated.
Described Fire extinguisher 41 is electrically connected to described valve 21, controls the keying of described valve.Fire extinguisher can be realized by the microprocessor with certain logical operation function and input/output function, for example can select single-chip microcomputer or Programmable Logic Controller (PLC) etc. for use.
For the bigger electrical control cubicles of volume, fire detector 42 can be provided with a plurality of, is located at diverse location respectively according to the point that needs in the wind generating set engine room electrical control cubicles to detect, and less then is provided with at least one.Each fire detector 42 can be independent Smoke Sensor or temperature sensor, also can be Smoke Sensor or temperature sensor are integrated among the fire detector.Fire detector 42 can satisfy the fire alarm condition, when for example reaching uniform temperature or amount of smoke, exports an alarm signal, and is transferred to Fire extinguisher 41.
After Fire extinguisher is received alarm signal, carry out the fire extinguishing operation, by-pass valve control 21 is opened, and discharges extinguishing chemical, and sends AISs to audible-visual annunciator 43, and guide sound light crossing-signal 43 sends alarm signal, as the light of flicker or buzzing etc.
The benefit that increases hand control switch 45 is can play effectiveness to guarantee fire extinguishing system when the fire detector accident is malfunctioning by thinking control fire extinguishing system enforced opening.Hand control switch 45 can be common key switch, and it is connected to a certain input interface of Fire extinguisher, presses 45 generations of hand control switch, one enforced opening signal and sends to Fire extinguisher 41., carries out Fire extinguisher 41 the fire extinguishing operation in case detecting the enforced opening signal.
Described fire extinguishing operation is except necessary control Open valve 21 and 43 warnings of guide sound light crossing-signal, because extinguishing chemical is to enter electrical control cubicles 1 through the pipeline 3 that seals, and close under the common state of electrical control cubicles, when fire takes place, encourage firepower and can not arbitrarily open in order to prevent that a large amount of air from entering, therefore, whether extinguishing chemical has been released and can not have obtained effective monitoring on earth.Gas discharges being provided with formally in order to address this problem of gate light 46, and Fire extinguisher 41 discharges gate light 46 to gas and sends one and light control signal after by-pass valve control 21 is opened, and gas discharges gate light 46 to be subjected to describedly to light the control of control signal and open.Like this, the staff promptly knows the release conditions of extinguishing chemical by the light on and off of observing light.
Under the prerequisite of the control logic of known Fire extinguisher, the establishment of specific procedure does not need performing creative labour to realize for a person skilled in the art, and multiple way of realization is arranged, and does not add at this and gives unnecessary details.
In addition, can also set up an input/output module 44 that communicates to connect with Fire extinguisher 41 again, this input/output module can be one group of human-computer interaction interface that is made of keypad and display screen, is used for Fire extinguisher is carried out the modification of parameter or program; Also can be a communication interface, be used to make a Fire extinguisher and a host computer to communicate.
In actual the use, extinguishment control system shown in many picture groups 2 can be constituted large-scale distributed monitoring system together, each extinguishment control system is connected to an electrical control cubicles, each Fire extinguisher is connected to host computer by input/output module, except that the fire extinguishing control of carrying out each electrical control cubicles, also the information of fire monitoring device is sent to the host computer of distributed monitoring system, receives the control of host computer.
Perhaps, also Fire extinguisher can be connected respectively to by-pass valve control and many group fire detectors of many group extinguishing chemical storage bottles, every group of fire detector is located at the place, corresponding control point of an electrical control cubicles, judge by Fire extinguisher, when K group fire detector is reported to the police, promptly the valve opening of the extinguishing chemical storage bottle of the corresponding corresponding electrical control cubicles of control is put out a fire.
By the control corresponding point is set, can carry out unified management to fire extinguishing system in the switch board of wind power generating set.By above-mentioned installation and control, the wind-powered electricity generation unit can be monitored the equipment in the electrical control cubicles of cabin in running all the time, according to actual conditions, carries out outfiring alarm or fire-fighting work, reduces the loss of blower fan fire.
By above-mentioned installation and control, wind-powered electricity generation unit electrical control cubicles can stop naked light or minimizing to cause the probability of fire in running, reduces the loss of blower fan fire.That this system has is simple in structure, function admirable, control mode advanced person, safe, advantage such as operating maintenance is convenient.
More than be illustrative to description of the present utility model; and it is nonrestrictive; those skilled in the art is understood, and can carry out many modifications, variation or equivalence to it within spirit that claim limits and scope, but they will fall in the protection domain of the present utility model all.
