Description

Long-range fire protection warning device

Technical field

The utility model relates to a kind of long-range fire protection warning device, belongs to the structural fire protection technical field.

Background technology

In the design of construction work now, tend to run into the shared cover fire pump of many buildings multi-story structure group or high residential building thing group, as buildings such as campus district, residential quarters, plant areas etc.These buildingss need should be provided with brokenly the glass button at each hose saddle place, and alarm bell is set according to the requirement of draining specialty.After the broken glass button actions of arbitrary buildings, answer across-the-line starting hose saddle pump, the alarm bell of this buildings of linkage sends alarm of fire.Prior art is that broken glass button of the hose saddle of every building buildings and alarm bell are all inserted the AC24V control loop of hose saddle pump control box, thereby constitutes a kind of fire protection warning device (as shown in Figure 2).Though this fire protection warning device can satisfy structural fire protection warning requirement to a certain extent, also there is following shortcoming in it: the input power supply of (1) this device is 24V, exists the bigger loss of voltage in Long-distance Control; (2), the cost of device is increased because each building, building all needs to quote four power transmission lines to broken glass button and alarm bell from the water pump control box; (3) cause each buildings circuit from the water pump control box and adopt 24V, need lay separately, the inconvenience that causes circuit to connect.

The utility model content

The purpose of this utility model is that for the loss of voltage that overcomes existing fire protection warning device existence is big, circuit connects inconvenience and the high shortcoming of cost, and a kind of long-range fire protection warning device is provided.

The utility model is achieved by taking following technical scheme: a kind of long-range fire protection warning device, constitute by fuse, power light, transformer, auxiliary reclay, water pump control box, broken glass button and alarm bell, described fuse is serially connected in an end of the input end of transformer, power light is attempted by on the input end of transformer, described auxiliary reclay is connected on the output terminal of transformer, and water pump control box, broken glass button and alarm bell are connected respectively to the auxiliary contact of auxiliary reclay.

The utility model is further improved: described auxiliary reclay has several auxiliary contact, these auxiliary contact force lamp device, fire-fighting blower fan linkage and elevator forced landing device etc. to be connected with non-fire-fighting power supply switching device shifter, emergency lighting respectively, realize the integrated of fire protection warning series.

Compared with prior art, the utlity model has following advantage:

One, the utility model adopts the transformer of the control power supply access device of 220V, is inversely proportional to voltage squared according to the loss of voltage, and the loss of voltage of long-range fire-fighting control is reduced; Simultaneously, this device only need be drawn two signal control lines to the water pump control box from each buildings, draw four control lines to every building buildings and need not as present fire plant, need control control box from water pump, reduced the quantity of control line, thereby the cost of investment of device is reduced.

Two, relay of the present utility model can be connected to non-fire-fighting power supply switching device shifter simultaneously, lamp device, fire-fighting blower fan linkage and elevator forced landing device are forced in emergency lighting, instruct crowd evacuation and the operation that drives the Smoke prevention ventilation unit in the buildings, realize the integrated of fire-fighting system.

Three, the utility model causes water pump control box circuit from each buildings and adopts 220V, circuit can lay together along the forceful electric power cable duct, avoid causing each buildings circuit from the water pump control box in the present technology and adopt 24V, the problem that need lay separately makes long-range fire protection warning device line arrangement more convenient.

Four, control section volume of the present utility model is little, and wiring is very simple, can directly be arranged in every building buildings duty room or the electric room, makes things convenient for the ruuning situation of staff's testing fixture.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.

Specific embodiment:

As Fig. 1 Fig. 3, shown in Figure 4, the utility model is made of fuse 1, power light 2, transformer 3, auxiliary reclay 4, water pump control box 5, broken glass button 6 and alarm bell 7, described fuse 1 is serially connected in an end of the input end of transformer 3, power light 2 is attempted by on the input end of transformer 3, described auxiliary reclay 4 is connected on the output terminal of transformer 3, and water pump control box 5, broken glass button 6 and alarm bell 7 are connected respectively to the auxiliary contact of auxiliary reclay 4.The control section that is made of fuse 1, power light 2, transformer 3 and auxiliary reclay 4 can directly be arranged in every building buildings duty room or the electric room.Fuse is as the overload and the short-circuit protection of operation circuit; Power light shows whether operate as normal of control power supply, and is not bright as power light, should check whether whether fault or control power supply have electricity etc. to circuit; Transformer to AC24V, provides broken glass button of hose saddle and alarm bell control power supply with the AC220V transformation; Auxiliary reclay sends brokenly glass button actions signal starting hose saddle pump, and the alarm bell of this buildings of linkage sends alarm of fire.

Control power supply of the present utility model adopts 220V, in order to guarantee long-range fire protection warning device power supply reliability, power supply is taken from every building building ' s fire equipment panel box and allots a 220V current supply circuit, as the locality fire-fighting power supply is not arranged, can take from the fire pump panel box and allot a 220V current supply circuit, broken glass button of each layer hose saddle and alarm bell insert long-range fire protection warning device, and one group of normally opened contact of the auxiliary reclay of long-range fire protection warning inserts the 220V control loop of water pump control box.As the locality fire-fighting power supply is arranged, draw two lines (220V) to the water pump control box, fire-fighting power supply is not arranged, draw four lines (220V) to the water pump control box from each buildings as the locality from each buildings.

In this practical example, the auxiliary reclay that is adopted has several auxiliary contact, these auxiliary contact force lamp device, fire-fighting blower fan linkage and elevator forced landing device etc. to be connected with non-fire-fighting power supply switching device shifter, emergency lighting respectively, simultaneously, on these auxiliary contact, be provided with pilot lamp, whether display device can transmit signal, has realized the integrated of fire protection warning.

The course of work of the present utility model is as follows: after the broken glass button actions in arbitrary buildings, the normally opened contact of auxiliary reclay can be closed, connect alarm bell and send sound and light alarm, and insert the normally opened contact starting hose saddle pump of water pump control box by another group of auxiliary reclay.Simultaneously, other contacts of this auxiliary reclay can be closed, signal is delivered to non-fire-fighting power supply switching device shifter, emergency lighting pressure lamp device, fire-fighting blower fan linkage and elevator forced landing device respectively, make these device operations, thereby instruct crowd evacuation and the operation that drives the Smoke prevention ventilation unit in the buildings, realize the integrated of fire-fighting system.
