Detailed Description
The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.
Example 1
As shown in fig. 1-4, an isolated fireproof cable trench comprises a cable trench body 1, wherein a plurality of cables 3 axially arranged along the cable trench body 1 are fixed in the cable trench body 1 through a plurality of fixing frames 2, and the above cables are in the prior art and are not described in detail again.
Fixed mounting has the baffle 4 that the polylith evenly set up in cable pit body 1, and many cables 3 all run through the setting of baffle 4, all form compartment 5 (as shown in figure 1) between per two baffles 4, separate into a plurality of independent compartments 5 with the cable pit, and when the fire incident took place, corresponding compartment 5 can be sealed rapidly, and oxygen in the compartment 5 can be consumed very fast to reach the effect of putting out a fire, the security is higher.
Every baffle 4's last lateral wall all is equipped with strip groove 6, the upper end demountable installation of cable pit body 1 has polylith apron 7, the equal fixedly connected with bar bellows 8 of one end of lateral wall under every apron 7, it needs to explain, the equal fixedly connected with counter weight strip 12 of the lower extreme of every bar bellows 8, counter weight strip 12 can drive bar bellows 8 and extend fast and seal compartment 5, counter weight strip 12 matches the setting with strip groove 6, can effectively improve the leakproofness, put out a fire fast.
The cover plate 7 is internally provided with a cavity, a magnetic sliding plate 9 is connected in the cavity in a sealing and sliding manner, the magnetic sliding plate 9 divides the cavity into a driving cavity 10 and a bearing cavity 11 filled with an evaporating liquid, the evaporating liquid can be dichloromethane, the boiling point is 40 ℃, and the evaporating liquid can be vaporized when the temperature reaches the boiling point, so that the magnetic sliding plate 9 is pushed to slide.
When a fire disaster occurs in the cable trench, the evaporation liquid in the upper end cover plate 7 of the corresponding compartment 5 absorbs heat to vaporize, the upper end of the strip-shaped corrugated pipe 8 is communicated with the driving cavity 10, the strip-shaped corrugated pipe 8 is driven to move downwards, and the corresponding compartment 5 is sealed, so that the fire extinguishing effect is achieved.
A driving mechanism is arranged in the driving cavity 10, specifically, the driving mechanism includes a plurality of connecting ropes 13 fixedly connected to the side wall of the magnetic sliding plate 9, and the other ends of the connecting ropes 13 extend into the strip-shaped corrugated pipe 8 and are fixedly connected to a counterweight strip 12 at the bottom of the strip-shaped corrugated pipe 8 (as shown in fig. 3 and 4).
The invention can be illustrated by the following operating modes:
when the invention is used, under normal conditions, the strip-shaped corrugated pipe 8 is positioned at the upper end of the partition plate 4 (as shown in figure 2), and the ventilation and heat dissipation effects of the cable 3 can be effectively ensured.
When the conflagration breaks out in the cable pit body 1, the evaporation liquid in the 5 upper end cover plates 7 of compartment that correspond can absorb the heat and take place the vaporization, promote magnetism sliding plate 9 and remove to the direction that is close to bar bellows 8, because the counter weight strip 12 fixed connection of magnetism sliding plate 9 and bar bellows 8 bottom, therefore can drive bar bellows 8 downstream, counter weight strip 12 can the joint in the strip groove 6 of 4 upper ends of baffle, compartment 5 that will correspond is sealed, oxygen in the compartment 5 can be consumed very fast, thereby reach the effect of putting out a fire, the security is higher.
Example 2
As shown in fig. 5, the present embodiment is different from embodiment 1 in that: the side wall of the cover plate 7 is fixedly connected with a warning box 14, one end in the warning box 14 is fixedly connected with a contact piece 15, the warning box 14 is internally and slidably connected with an electric contact block 16 which is opposite in polarity to the magnetic sliding plate 9, and the electric contact block 16 can slide in the warning box 14 along with the movement of the magnetic sliding plate 9.
The lateral wall fixed mounting has on apron 7 and touches electric piece 15 and the equal coupled alarm 17 of electric block 16, and alarm 17 establishes ties on the circuit of electric piece 15 and electric block 16, and whole circuit switch-on when touching electric piece 15 and touching electric block 16 contact is worth mentioning, and the lateral wall is fixed to be run through there is the whistle pipe 18 on warning box 14, and the vertical setting of whistle pipe 18.
In this embodiment, when the magnetic sliding plate 9 slides in the cavity in case of fire, the touch pad 16 will be driven to slide, the alarm box 14 will generate sharp sound through the whistle tube 18 due to the suddenly increased air pressure, and when the touch pad 16 contacts the touch piece 15 to turn on the alarm 17, the alarm 17 will give an alarm in time, thereby further improving the safety.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
