Description

Fireproof server support

Technical Field

The utility model belongs to the technical field of the shell of electrical equipment or spare part.

Background

Therefore, ventilation and heat dissipation effects of common server cabinets in the market are emphasized, but once the server cabinets with good ventilation effects meet a fire disaster, the flame spread range can be increased, flame is fully combusted for conveying air for flame, the flame quickly spreads to the core part of the server, and effective protection cannot be performed on the server, so that serious property loss is caused.

For example, chinese patent application (publication No. CN104423480A) discloses a server cabinet, which is provided with a plurality of main fan sets for dissipating heat of servers placed on the server cabinet. The server cabinet is also provided with a conveying mechanism and a standby fan set, the conveying mechanism bears the standby fan set and can drive the standby fan set to move in the server cabinet, and the main fan sets and the standby fan sets are respectively positioned on different planes. When any main fan set fails and stops working, the standby fan set is moved to the position corresponding to the main fan set with the failure through the transmission mechanism to replace the main cooling fan with the failure to cool the corresponding server.

Although the technical scheme can enhance the air circulation in the server cabinet, when a fire disaster occurs, the fan can play a combustion-supporting effect on flame instead, and the server cannot be effectively protected.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a fire prevention type server support to the problem of the unable timely protection server when solving and meetting the conflagration.

In order to achieve the purpose, the utility model discloses a basic scheme provides a fire prevention type server support, including the pedestal, be equipped with a plurality of stands on the pedestal, be equipped with a plurality of horizontal poles between the adjacent stand, open the recess in the horizontal pole and trigger the chamber, trigger the chamber and be linked together with the recess, trigger the intracavity and be equipped with control by temperature change ignition, be equipped with in the recess and triggering the fire-resistant gasbag that control by temperature change ignition back inflation, the fire-resistant gasbag after the inflation encloses into a plurality of confined spaces.

The principle of the basic scheme is as follows: when the fireproof server support encounters fire, the temperature control detonating device is heated and is triggered to detonate to inflate the fireproof air bag, the fireproof air bag is popped out from the cavity of the cross rod in the inflating process, and a closed space formed by the popped fireproof air bag can be used for surrounding and sealing the server. The self fire resistance of the fire-resistant air bag is recycled, the flame isolating effect is achieved on the server, and the effects of protecting the server and preventing the server from being burnt are achieved.

The beneficial effect of this basic scheme lies in: compare in prior art's server support, this basic scheme can pop out fire-resistant gasbag and in time carry out isolated protection to the server when meetting the condition of a fire, avoids server core data to be burnt the damage. The safety of the core electrical element of the server is protected, so that the core electrical element can be continuously used, and the loss of an enterprise is reduced.

Further, the horizontal pole includes the bracing piece, the recess quantity of bracing piece is two, sets up top position and bottom position in the bracing piece respectively.

As shown in fig. 2, the top and bottom positions of the support rod are vertical directions relative to a vertical horizontal plane when the support rod is in an installed state.

The support bar is relative to the horizontal plane. The fire-resistant air bag which expands when heated extends out of the cross rod through the groove and plays a role in protecting and separating the side wall of the server in the vertical direction.

Furthermore, the side wall of the supporting rod is provided with a blind hole.

The server is hooked on the support rod by utilizing the blind hole of the support rod, and then the purpose that the server case is fixed to the fireproof server support is achieved.

Furthermore, the horizontal pole still includes the fender rod, fender rod height position is located between the adjacent bracing piece, the recess quantity of fender rod is three, sets up respectively in the top position of fender rod, bottom position and be close to one side at pedestal center.

Because the trigger cavity is arranged on one side far away from the base body, when a fire occurs, the temperature of the trigger cavity can be firstly raised, so that the temperature-controlled detonating device in the trigger cavity is firstly subjected to thermal explosion.

Furthermore, the fire-resistant air bag is of a box-packed structure after being expanded.

Each end face of the box-packed structure is a plane, and the end faces of the fire-resistant air bags are abutted against the end faces after expansion, so that the sealing property between the adjacent fire-resistant air bags is effectively improved.

Further, the ends of the two fire-resistant airbags that expand in opposite directions away from the crossbar interfere with each other.

After the two opposite fire-resistant air bags are expanded, the end parts of the fire-resistant air bags far away from the cross rod are mutually abutted, so that the fire-resistant air bags are separated from one side surface to be protected. Compare in the direct protection side of single fire-resistant gasbag, the volume that occupies of single fire-resistant gasbag can effectively be saved to this scheme, is convenient for more during fire-resistant gasbag packs into the inner chamber of horizontal pole.

Furthermore, one end of the fire-resistant air bag, which is far away from the cross rod, is provided with a plurality of magnet blocks.

The magnet pieces of its tip can adsorb each other together after the inflation of two relative fire-resistant gasbags, and then guarantee the sealing performance that relative fire-resistant gasbags contradict after the inflation.
