FIG. 2 is a schematic view of an internal cross-section of a support ring of the present invention;
fig. 3 is a diagram showing a state of use of each communication host according to the present invention after a fire occurs.
Detailed Description
As shown in fig. 1, the arrangement structure of the communication hosts in the computer room comprises an independently arranged communication computer room 1 and more than one communication hosts 4 arranged in the communication computer room 1, wherein a cabinet door 7 is arranged on one side surface of each communication host 4, the more than one communication hosts 4 are arranged against the wall of the communication computer room 1, and a through installation cavity 5 is arranged on the wall of the communication computer room 1 and faces each communication host;
5 inner walls of installation cavity encircle 5 rounds of installation cavity and all install a support ring 2, the centre of support ring 2 has a support cavity, 4 parts of communication host computer are buckled in the support cavity, the cooling surface of communication host computer 4 stretches out in 4 outsides of communication computer lab and with the outside air contact, the support ring 2 is sealed with communication host computer 4 and communication computer lab 1, one side of 1 wall body of communication computer lab all sets up a closing plate 8 is kept away from to every communication host computer 4, prop through the elasticity of the elastic tension device more than one between closing plate 8 and the communication computer lab wall body and open.
In this embodiment, the elastic stretching devices all include a spring 9 and a support rod 11, one end of the spring 9 is fixedly installed in the spring positioning cavity inside the communication machine room wall through glue, the other end of the spring is bonded and fixed with one side surface of the sealing plate 8 through glue, and the support rod 11 is arranged inside the spring 9 and used for supporting the spring 9 and supporting the communication machine room wall and the communication host 4.
When the communication host computer normally used, the spring passes through the bracing piece and backs down tensile, and more than half communication host computers this moment are located the computer lab inside, and the cooling surface is located the outside, realizes the heat dissipation to the communication host computer, consequently as long as the bracing piece has the holding power, whole communication host computer can keep this kind of state always, and the accessible cabinet door realizes overhauing, owing to set up the support ring, and external and computer lab inside is cut off, has guaranteed the leakproofness.
In this embodiment, two sides of the bottom of the sealing plate 8 are respectively provided with a lug, a roller 6 is installed between the two lugs, the bottom of the roller 6 is in rolling contact with the ground of a communication machine room, and the rolling when the communication host is displaced is realized through the roller 6, so that the friction force is greatly reduced, and the communication host is better recovered.
As shown in fig. 2, the support ring 2 includes a metal ring 25 made of a metal material, the metal ring 25 is hollow and forms a liquid storage cavity 22, water or cooling liquid is stored in the liquid storage cavity 22, a layer of elastic rubber layer 21 is wrapped outside the metal ring 25, one side of the metal ring 25 located in the support cavity is provided with more than one first through hole 24, the elastic rubber layer 21 facing the first through hole 24 is provided with a second through hole 23, the communication host 4 is provided with sealing columns 41 facing the first through hole 24 and the second through hole 23, and the sealing columns 41 are partially buckled in the second through hole 23 and seal the open end of the second through hole 23. When normal use, by sealed post seal first, the second through-hole, the water of stock solution intracavity can not run out this moment, after the communication host computer displacement, sealed post and the forced separation of second through-hole, the water or the coolant liquid of stock solution intracavity can run out this moment, because the communication host computer is frictional contact between displacement in-process and support ring, even so the communication host computer outside has the naked light, also can extinguish through frictional force and the water that runs out, the inside water of support ring or coolant liquid can reach radiating purpose to the communication host computer simultaneously, further promote the heat-sinking capability.
Wherein, bracing piece 11 adopts a flammable plastics pole, in this embodiment, sealed post is the sealed post of rubber, when the indoor conflagration that takes place, flame can destroy flammable plastics pole at first this moment the spring loses the power of strutting, under the effect of spring, whole communication host computer resets, move towards wall body one side, and finally utilize the sealed installation cavity of closing plate, reach and the external communication host computer between the wall, prevent the transmission of flame, because communication host computer displacement to the external world, so flame just can not transmit on the host computer yet, win a large amount of time for the rescue, as shown in fig. 3, greatly reduced economic loss.
In this embodiment, the heat dissipating surface of the communication host 4 is provided with the heat dissipating blades 3, and the heat inside the host is further dissipated to the outside through the heat dissipating blades 3.
The heat dissipation surface is always positioned outside the machine room, so that heat cannot be concentrated, the heat dissipation capacity is very good, and the service life of the communication cabinet is prolonged;
the invention can enable the supporting rod to lose supporting force when a fire disaster happens, further enables each communication host to reset, enables each communication host to move to the outside of a machine room, isolates a fire source through the sealing plate, extinguishes the fire source in the moving process, and is safer to use.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
