Detailed description of the invention
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the present invention is further elaborated.
As it is shown in figure 1, the one non-wet environment Fuse Type cable connector fireproof protection box provided for the present invention, this is prevented
The inside of fire protecting box 3 has a cavity, in order to accommodate cable connector 2；It is provided with fire prevention radiating part on this fireproof protection box 3
Part, and the Fuse Type drive mechanism being connected with this fire prevention thermal component；Described Fuse Type drive mechanism has and presets temperature
The fusing point that degree warning value is suitable；When the real time temperature in fireproof protection box 3 is not above preset temperature warning value, fire prevention dissipates
Thermal part is in normally open, and beneficially cable connector 2 dispels the heat；When the real time temperature in fireproof protection box 3 exceedes preset temperature police
During ring value breaking out of fire, Fuse Type drive mechanism fuses, and controls thermal component closedown of preventing fires, and makes fireproof protection box 3 form envelope
Close space, stop fire to prolong combustion；Blast is there is but reality in fireproof protection box 3 when cable connector 2 is assembled rapidly because of internal heat
When Shi Wendu has not exceeded preset temperature warning value, normally opened fire prevention thermal component can provide pressure release passage effectively, and moment releases
After exoergic, such as secondary fire, when the real time temperature in fireproof protection box 3 persistently raises and exceedes default warning value, Fuse Type
Drive mechanism fuses, and controls fire prevention thermal component and closes, make fireproof protection box 3 be formed and close space, stops fire to prolong combustion.
Described fireproof protection box 3 is mutually spliced assembling by the identical upper shell 5 of structure and lower house 6 and is formed, uses easy
The mode connected in dismounting assembles, it is simple to the installation of cable connector 2 and maintenance；And described upper shell 5 and lower house 6 by
Fire proofing material is made, and fire proofing material and specification need to be adapted to the fire endurance of field of employment.
As in figure 2 it is shown, described upper shell 5 comprises the first framework 52 and the first fire prevention thermal component；This first fire prevention dissipates
Thermal part comprises multiple first be separately positioned on the end face of the first framework 52 and each side and rotates BAIYE 53；Each first
Rotate BAIYE 53 to be connected with the first Fuse Type drive mechanism 56 by one first power transmission shaft 54 respectively；When in fireproof protection box 3
When real time temperature exceedes preset temperature warning value, the first Fuse Type drive mechanism 56 fuses, and by each first power transmission shaft 54
Control each the first rotation BAIYE 53 to close.
As shown in Fig. 3～Fig. 5, described lower house 6 comprises the second framework 62 and the second fire prevention thermal component；This second prevent
Fire thermal component comprises multiple second be separately positioned on the bottom surface of the second framework 62 and each side and rotates BAIYE 63；Each
Second rotates BAIYE 63 is connected with the second Fuse Type drive mechanism 66 by a second driving shaft 64 respectively；When fireproof protection box 3
When interior real time temperature exceedes preset temperature warning value, the second Fuse Type drive mechanism 66 fuses, and by each second transmission
Axle 64 controls each the second rotation BAIYE 63 and closes.
In the present embodiment, BAIYE 53 can be rotated according to first and the second rotation BAIYE 63 does not the most affect cable
The installation of joint 2 and the size of maintenance principles design blade.
The first described Fuse Type drive mechanism 56 and the second Fuse Type drive mechanism 66 can use fusible metal sheet to realize.
The both sides of described fireproof protection box 3 are respectively arranged with cable aperture, in order to through the two ends with cable connector 2 respectively
The power cable 1 connected, and the gap location between this cable aperture and power cable 1 is filled with fire resistant flexible material 4.
As shown in Figures 2 and 3, described cable aperture by be correspondingly arranged on upper shell 5 first cable aperture pillow 55, and
The the second cable aperture pillow 65 splicing composition being correspondingly arranged on lower house 6.
As shown in Figures 2 and 3, the two bottom sides of described upper shell 5 is provided with outward extending first connecting plate 57, uses
In connecting, the first drive mechanism 56 is installed；The both sides, top of described lower house 6 are provided with outward extending second connecting plate 67,
For connecting installation the second drive mechanism 66；By being connected to realize upper shell with the second connecting plate 67 by this first connecting plate 57
5 assemble with the splicing of lower house 6.In the present embodiment, it is possible to use connector correspondence is through being arranged on the first connecting plate 57
First installing hole 51, and the second installing hole 61 being arranged on the second connecting plate 67, thus realize the first connecting plate 57 and
Fixing connection between two connecting plates 67.
The first described Fuse Type drive mechanism 56 and the second Fuse Type drive mechanism 66 are also reported automatically with outside fire
Alarm system (automatic fire alarm system personal in such as tunnel) communication connection, it is reported automatically to this fire while fusing
Alarm system output coordinated signals signal, to enable automatic fire extinguisher.
Non-wet environment Fuse Type cable connector fireproof protection box provided by the present invention, under normal circumstances, fire prevention
Real time temperature in protecting box 3 is not above preset temperature warning value, now each first rotate BAIYE 53 and each
Second rotates BAIYE 63 is in normally open, and beneficially heat radiation and the energy of cable connector 2 is released, to avoid heat to protect in fire prevention
Assemble in protecting box 3 thus cause blast or fire.Occur when the real time temperature in fireproof protection box 3 exceedes preset temperature warning value
During fire, the first Fuse Type drive mechanism 56 and the second Fuse Type drive mechanism 66 reach fusing point fusing, pass through one-time action
Control each first rotation BAIYE 53 respectively and each the second rotation BAIYE 63 is closed, make fireproof protection box 3 form a closing
Space, carries out fire damping, stops the tongues of fire to be scurried out, and prevents fire from prolonging and fires to adjacent cable, meets a road power cable and fire occurs
Calamity or explosion time, do not prolong and fire the use requirement to other cables laid with tunnel, beneficially the condition of a disaster control.Further, when first
Fuse Type drive mechanism 56 and the second Fuse Type drive mechanism 66 are while fusing, and it also can be defeated to automatic fire alarm system
Go out coordinated signals signal, thus enable automatic fire extinguisher.When cable connector 2 assembles rapidly generation blast but anti-because of internal heat
When real time temperature in fire protecting box 3 has not exceeded preset temperature warning value, normally opened fire prevention thermal component can provide effectively
Pressure release passage, after transient burst of energy, such as secondary fire, the real time temperature in fireproof protection box 3 persistently raises and exceedes default
During warning value, the first Fuse Type drive mechanism 56 and the second Fuse Type drive mechanism 66 fuse, and control each the first rotation BAIYE
53 and each second rotate BAIYE 63 close, make fireproof protection box 3 formed close space, stop fire prolong combustion.Fire suppression
After, need to change two Fuse Type drive mechanisms, and manually open each and first rotate BAIYE 53 and each second turn
Dynamic BAIYE 63 so that it is be in normally open.
Although present disclosure has been made to be discussed in detail by above preferred embodiment, but it should be appreciated that above-mentioned
Description is not considered as limitation of the present invention.After those skilled in the art have read foregoing, for the present invention's
Multiple amendment and replacement all will be apparent from.Therefore, protection scope of the present invention should be limited to the appended claims.
