Description

A kind of Multi-media box
Technical field
The present invention relates to a kind of access network casing, more particularly to a kind of Multi-media box.
Background technology
It is with the increasingly fierceness of telecommunication market competition, existing with copper cable as transmission medium, based on asymmetric digital subscriber Line(ADSL) the Construction of Broad Band pattern based on technology will not adapt to that following to carry out HD video, security monitoring contour The demand of rate bandwidth business." light entering and copper back " effective measures broadband as network transformation and fixed network is implemented, connect in raising Enter bandwidth, lift enabling capabilities of the network to business, will play a significant role in terms of the core competitive for strengthening operator.
Multi-media box is the collection raising middle flask of weaker voltage circuit, is generally used in modern house finishing, such as netting twine, telephone wire, Antenna of TV etc. can be placed wherein;By so multiple wire plug connection in Multi-media box, and due to the inside of Multi-media box Narrow space, so the heat for easily causing generation can not be discharged in time, so as to the insulating barrier that can cause cable softens, is reduced The service life of cable, in some instances it may even be possible to there is the danger of electric leakage.If the artificial inside to Multi-media box is aerated or lowers the temperature, Then can make troubles to user, while it is difficult to accomplishing cooling in time.The problems referred to above, it would be highly desirable to solve.
The content of the invention
The present invention is directed to deficiency of the prior art, there is provided a kind of Multi-media box.
In order to solve above-mentioned technical problem, the present invention is addressed by following technical proposals:A kind of Multi-media box, including Multi-media box casing, the casing are socketed with case lid, are provided with base below the casing in cylinder, the casing, Arrange fluted on the base, the case lid is fastened in the groove, be from top to bottom disposed with the casing Public storehouse, socket connector and panel storehouse, are provided with wrapping post, several sockets are disposed with the socket connector in the public storehouse, Network interface panel, video interface panel and cylindrical magnet are provided with the panel storehouse, are arranged in the medial surface of the case lid There is spiral groove, the spiral groove rises to top from the lower part helical of the case lid, sets in the spiral groove Spiral guide rail is equipped with, and slide block and the second motor is provided with the guide rail, air pressure is provided with the slide block Cylinder, the pneumatic cylinder are connected with air pump, and the atmospheric pressure pole of the pneumatic cylinder is connected with air nozzle, are socketed with heat red on the air nozzle Outer induction installation;Top in the casing is provided with liquid nitrogen relieving mechanism, and the liquid nitrogen relieving mechanism includes a holding vessel, Liquid nitrogen is filled with the holding vessel, the holding vessel internal upper part is provided with the first motor, described first drives electricity Blade is provided with the output shaft of machine, the lower end of the holding vessel be symmetrically arranged with can folding baffle plate, before the baffle plate End is provided with automatically controlled inductive switch;The side wall of the casing is provided with heat sensor;It is additionally provided with the public storehouse Controller.
In order to obtain superior technique effect, further technological improvement also includes that the lower end of the holding vessel is provided with Two pieces of sealing gaskets, the sealing gasket are inlaid into inside the holding vessel, and the upper surface of the baffle plate is provided with boss, the boss It is embedded in the sealing gasket, the end face of one piece of sealing gasket arranges fluted, and the end face of another piece of sealing gasket is provided with With the projection of the fit depressions.So arrange, sealing gasket can be sealed liquid nitrogen inside holding vessel up for safekeeping, when opening baffle plate When, baffle plate turning can drive sealing gasket to open, and then discharge liquid nitrogen.
In order to obtain superior technique effect, further technological improvement also includes, arranges on the side wall of the casing The heat sensor correspond to the area of space in the public storehouse, socket connector and panel storehouse respectively.So arrange, at each Heat sensor is provided with storehouse in area of space, it is ensured that after the intensity of a fire being found in casing, temperature is believed by heat sensor in time Number value feeds back to controller, so as to put out a fire in time.
In order to obtain superior technique effect, further technological improvement also includes, arranges in the upper surface of the casing There is fire alarm.So arrange, the information that the intensity of a fire occurs in Multi-media box is passed to into the external world in time in time, related personnel is allowed Overhaul in time.
In order to obtain superior technique effect, further technological improvement also includes, arranges on the automatically controlled inductive switch There is bracing frame, support frame as described above is arranged in 90 degree with the baffle plate.So arrange, after baffle plate is opened, bracing frame is to baffle plate It is supported so that become V-type mouth, facilitates the release of liquid nitrogen.
The present invention operation principle be:When the aggregation in Multi-media box due to heat causes box interior temperature to raise or short After the initiation fire of road, after the heat sensor of box house experiences temperature anomaly, signal is fed back to into controller, controller makes Fire alarm sends alarm, while controller sends control signals to pneumatic cylinder and the second motor, second Motor drives slide block on spiral-shaped guide to move and overturn, and can include casing in 720 degree of tours in casing, area coverage Interior most areas, while starting pneumatic cylinder, atmospheric pressure pole stretches out so that air nozzle is reached in fire area, thermal infrared Induction installation can automatically detect fire area so that air nozzle automatic adjusting position is directed at fire area, after air pump starts, spray Valve sprays gases at high pressure by spark extinguishing.If above-mentioned fire extinguishing is not completed, controller receives heat sensor again Signal after, after starting automatically controlled inductive switch, sealing gasket while baffle plate is opened, can be driven to overturn, bracing frame enters to baffle plate Row is supported so that baffle plate becomes V-type mouth, while the first motor drives blade to drive downwards liquid nitrogen, liquid nitrogen is outspoken by V-type Speed is accurately slipped to region to be put out a fire, and as the temperature of liquid nitrogen is very low, temperature drop rapidly causes the intensity of a fire of fire area Extinguish, and then fire is put out completely.Extinguishing device is so set and not only avoid the short circuit phenomenon that fibre circuit is caused using water, And good extinguishing effect, reach the purpose of control intensity of a fire guard box in-vivo device.
The invention has the beneficial effects as follows:By removable spiral jetting device and liquid that uniqueness is arranged in Multi-media box Nitrogen relieving mechanism, to the esoteric intensity of a fire of case, is first put out using gases at high pressure, and 720 degree are maked an inspection tour without dead angle, then can use liquid Nitrogen is put out a fire, and not only avoid the short circuit phenomenon that fibre circuit is caused using water, and good extinguishing effect, reaches control intensity of a fire protection The purpose of case in-vivo device;The device such as the heat sensor being arranged in casing and controller, ensure that After gesture, temperature signal value is fed back to controller by heat sensor in time, reaches the purpose of timely fire extinguishing.Intelligent fire extinguishing, peace It is complete practical.
