When a fire breaks out, the fire-fighting nozzle releases the fire extinguishing agent to extinguish the fire.
As shown in fig. 2, an exemplary cabinet with an automatic fire extinguishing function includes a fire extinguishing agent bottle 05 and a fire extinguishing pipe 06 connected to an outlet of the fire extinguishing agent bottle 05, the fire extinguishing pipe 05 is disposed outside the cabinet, and the fire extinguishing pipe 06 penetrates through an outer shell of the cabinet and extends into the inside of the cabinet, and is laid or fixed above an object to be protected 07. When a fire breaks out, the fire extinguishing pipe 06 is broken to spray the fire extinguishing agent to extinguish the fire.
In a first aspect, referring to fig. 3 and 4, an embodiment of the present application provides a cabinet 100, which is defined by a plurality of cabinet side plates 101, the inside of the cabinet 100 is used for arranging electrical equipment, one side of the cabinet side plate 101 facing the inside of the cabinet 100 is an inner side surface, and an ignition tube 102 is fixed to an inner side surface of at least one cabinet side plate 101 of the plurality of cabinet side plates 101.
The cabinet 100 provided by the embodiment of the application is, as shown in fig. 3 and 4, enclosed by a plurality of cabinet side plates 101, the inside of the cabinet 100 is used for setting electrical equipment, one side of the cabinet side plate 101 facing the inside of the cabinet 100 is an inner side surface, and the inner side surface of at least one cabinet side plate 101 in the plurality of cabinet side plates 101 is fixed with the fire detecting tube 102. Thus, the fire detecting tube 102 with the fire extinguishing function and the cabinet side plate 101 are fixedly assembled into a whole, the cabinet side plate 101 only needs to be installed on the cabinet 100 during installation, the installation is very convenient, the layout is not limited by the top of the cabinet, and the fire detecting tube can be arranged at any position of the cabinet side plate 101 corresponding to the interior of the cabinet, so that the problem of low reaction speed caused by the fact that the fire detecting tube is far away from a fire source is solved; in addition, the fire detecting pipe 102 is fixed to the cabinet side plate 101, and does not obstruct installation and maintenance of the electrical equipment.
The fire detecting tube 102 is fixed on the inner side surface of the cabinet side plate 101, and there may be various implementations, for example, the fire detecting tube 102 is fixed on the surface of the inner side surface of the cabinet side plate 101, or a groove is formed on the inner side surface of the cabinet side plate 101, so as to fix the fire detecting tube 102 in the groove. The scheme of directly fixing the outer surface of the side plate 101 of the cabinet is convenient to install, and the scheme of forming the groove can enable the fire detecting tube 102 to be fixed more firmly. Of course, which scheme is specifically adopted can be selected according to actual needs. Meanwhile, the thickness of the cabinet side plate 101 also affects the selection of the fixing scheme, for example, when the thickness of the cabinet side plate 101 is relatively thin, a groove should not be formed so as to avoid affecting the overall strength of the cabinet side plate 101, and at this time, the fire detecting tube 102 can be directly fixed on the surface; if the thickness of the cabinet side plate 101 is thick, the groove does not affect the overall structural strength, and the fire detecting tube 102 can be fixed in the groove.
Optionally, the fire detecting tube 102 is fixed to the cabinet side plate 101 by a snap. The fixing of the fire detecting tube 102 and the cabinet side plate 101 may be bonding, clamping by a snap, etc.
In order to achieve a rapid fire extinguishing reaction at all locations in the cabinet 100, the fire detecting tubes 102 may be distributed over the inner side of the cabinet side plate 101. Referring to fig. 3, the fire detecting tube 102 is filled with the inner side.
The fire detecting pipes are distributed on the inner side surface of the whole cabinet side plate 101, so that all positions in the cabinet 100 can be ensured to be in a fire extinguishing monitoring area, however, the scheme has the disadvantages of more materials and higher cost, and therefore, on the premise of considering the cost, the fire detecting pipes 102 can be properly arranged at positions where fire is not easy to happen, namely, the fire detecting pipes 102 are mainly arranged at positions where fire is easy to happen. Generally, a fire is likely to occur at a high temperature position in the cabinet 100, for example, near an electronic device in the cabinet 100, or a heat exchange outlet of the cabinet 100, and therefore, the position may be purposely arranged with the fire detecting tube 102.
Specifically, when the electronic device is disposed in the cabinet 100, the electronic device is easily heated and easily ignited, and therefore, the fire detecting tube 102 is disposed on the inner side surface of the cabinet side plate 101 near the electronic device, so as to extinguish the fire of the electronic device at the first time.
When the cabinet 100 is provided with the heat exchange air outlet, the temperature at the heat exchange air outlet is generally higher, and the fire is easily ignited, so the fire detecting tube 102 on the cabinet side plate 101 is arranged close to the heat exchange air outlet.
The number of the fire detecting tubes 102 may be one or more, a plurality of the fire detecting tubes 102 need a plurality of pipelines, and are mounted and fixed for a plurality of times, one fire detecting tube 101 needs to be in a winding and winding layout, and particularly, the number of the fire detecting tubes 102 or the number of the fire detecting tubes 101 can be selected according to actual needs. Referring to fig. 3, taking the fire detecting tube 102 as an example, the fire detecting tube 102 is distributed along the inner side surface of the cabinet side plate 101 in a winding way.
The arrangement of the fire detecting tubes 102 is various, and for example, referring to fig. 3, the fire detecting tubes 102 are arranged in an S-shape by being bent and detoured along the inner side surface of the cabinet side plate 101.
Specifically, referring to fig. 3, the fire detecting tube 102 includes a plurality of arrangement sections 1021 and a plurality of connection sections 1022, the arrangement sections 1021 are parallel to each other and are uniformly spaced, and the connection sections 1022 are used for connecting the arrangement sections 1021 end to end.
Generally, each size of the fire detecting tube 102 has an effective radius of detectable temperature along the radial direction, and if the radius is exceeded, the fire detecting tube 102 may not be able to detect and sense sufficient temperature successfully, and further may not break and fail to achieve the fire extinguishing effect. Therefore, the space between the plurality of arrangement sections 1021 needs to ensure that the effective temperature detection radius of the fire detection tube 102 can fully cover the space within the space. In addition, the fire detection pipes 102 are high in manufacturing cost and are broken and scrapped once being used, the fire detection pipes are disposable products, if the effective temperature detection radius is only guaranteed, the fire detection pipes 102 are densely arranged, the temperature detection radii of a plurality of pipelines can be overlapped, resource waste is caused, and the cost is increased. Therefore, based on the above considerations, after multiple use verification, optionally, on the premise that the effective temperature detection radius of the fire detection tube 102 can fully cover the monitoring area, the distance between two adjacent arrangement sections 1021 is greater than 130 mm, so as to ensure that the cost is reduced.
The specific arrangement of the fire detecting tubes 102 can be set according to actual needs, and when the fire detecting tubes are arranged in an S-shaped manner, taking the arrangement direction of the arrangement section 102 as an example, the arrangement can include three cases, namely horizontal arrangement and vertical arrangement which is already arranged at a certain angle with the horizontal direction. When the cabinet side plate 101 is mounted on the cabinet 100, the arrangement section 1021 is arranged in the horizontal direction as shown in fig. 5 and 6, or in the vertical direction as shown in fig. 3, or in an angle with the horizontal direction as shown in fig. 7.
Of course, the fire detecting tube 102 may have various implementations other than the S-shaped arrangement, such as a zigzag arrangement, other irregular arrangements, and the like. Referring to fig. 8, the fire detecting tubes 102 are arranged in a zigzag shape by being bent and detoured along the inner side surfaces of the cabinet side plates 101.
The cabinet 100 provided in the embodiment of the present application, referring to fig. 4 and fig. 6, includes a cabinet frame 103, and the cabinet side plate 101 may be integrally formed with the cabinet frame 103, or may be manufactured separately from the cabinet side plate 101 and then fixed to the cabinet frame 103. The fixing mode can be selected as detachable fixing, and the installation, the maintenance and the replacement are convenient.
Generally, it is necessary to leave a space on one side of the electrical equipment in the cabinet or to provide a door panel for the convenience of installation, maintenance, debugging and the like by a person, and therefore, referring to fig. 4 and 6, the cabinet side panel 101 of the cabinet 100 includes four side panels, namely, a front side panel, a rear side panel, a left side panel and a right side panel, for the convenience of operation by a person, may not be provided. Thus, cabinet side panels 101 include at least three cabinet side panels 101 located on the left, right, and rear sides of cabinet 100.
In order to ensure that the fire extinguishing agent in the fire detecting pipe 102 can be sufficiently extinguished and continuously sprayed out, the fire detecting pipe 102 can be further communicated with a fire-fighting gas cylinder 104, and the fire-fighting gas cylinder 104 can provide continuous fire extinguishing agent for the fire detecting pipe 102 so as to ensure that the fire is extinguished. In current scheme, fire control gas cylinder 103 often is located near the rack outside, like this, fire control gas cylinder 103 still needs independent extra setting mounted position, can extra occupation space, and it is far away from the rack, can influence the data (for example pressure in the bottle etc.) accuracy that detects, consequently, refer to fig. 4, when the visit firetube 102 intercommunication of rack curb plate 101 has fire control gas cylinder 104, in order to save the whole supporting occupation space of rack 100, and can not influence the accuracy that data detected, fire control gas cylinder 103 sets up inside rack 100. The fire detecting tube 102 has a fire extinguishing agent therein, which is broken by heating, and the fire extinguishing agent therein is rapidly released to the fire source for rapidly extinguishing the fire.
It should be noted that, when the fire detecting pipe 102 is further communicated with the fire fighting gas cylinder 104, for the scheme that the fire detecting pipes 102 are multiple, each fire detecting pipe 102 needs to be connected with the fire fighting gas cylinder 104, and further, multiple interface fittings may be needed to achieve installation and communication, so that assembly is difficult and tedious. The fire detecting pipe 102 can be selected as a whole pipe, and only a first end communicated with the fire-fighting gas cylinder 104 and a second end blocked are provided, so that the assembly of a plurality of interface fittings is omitted, the installation is convenient, and the cost is reduced.
In order to ensure that whether the fire extinguishing agent in the fire fighting gas cylinder is sufficient or not can be known at all times, the pressure detection meter is arranged on the fire fighting gas cylinder 104 and can be used for detecting the pressure in the fire fighting gas cylinder 104. Alternatively, as shown in fig. 4, the end of the fire detecting tube 102 is provided with a pressure detecting gauge 105 for detecting the pressure in the fire detecting tube 102.
It should be noted that the scheme of installing the pressure detection meter on the fire-fighting gas cylinder 104 and the scheme of installing the pressure detection meter at the end of the fire detecting tube 102 are both for knowing whether the pressure of the fire extinguishing agent is normal and ensuring smooth fire extinguishing in case of fire. During the specific implementation of the scheme, only the tail end of the fire detecting pipe 102 is provided with the pressure detecting meter, or only the fire fighting gas cylinder 104 is provided with the pressure detecting meter, or of course, both the tail end of the fire detecting pipe 102 and the fire fighting gas cylinder 104 are provided with the pressure detecting meters.
In a second aspect, an embodiment of the present application provides an enclosure group, including a plurality of enclosures 100 according to any one of the above aspects of the first aspect.
The cabinet group provided by the embodiment of the application comprises the cabinet 100 in any one of the schemes of the second aspect, so that the same technical effects are achieved, namely, the installation is very convenient, the position layout of the fire detecting tube 102 is not limited by the top of the cabinet 100, and the fire detecting tube can be arranged at any position of the side plate 101 of the cabinet corresponding to the inside of the cabinet 100, so that the problem of slow reaction speed caused by being far away from a fire source is avoided; in addition, the fire detecting pipe 102 is fixed to the cabinet side plate 101, and does not obstruct installation and maintenance of the electrical equipment.
When the plurality of cabinets 100 of the cabinet group are arranged and combined together, as shown in fig. 9 and 10, which are top views of two arrangements of the plurality of cabinets 100 of the cabinet group, if a fire occurs in one of the cabinets 100, the fire may spread to other adjacent cabinets 100 nearby, and therefore, in order to avoid the above problem, the plurality of cabinets 100 are arranged side by side in an abutting manner, and a fire detecting pipe 102 is disposed on each cabinet side plate 100 where two adjacent cabinets 100 contact each other.
