Detailed Description
The present invention will be further explained below for better understanding of the objects, technical solutions and technical effects of the present invention, but the scope of the present invention is not limited to the following examples.
Example 1
As shown in figure 1, the fusible shedding structure for the sound insulation cover of the extra-high voltage power transmission and transformation equipment comprises a top part and a front end part, wherein the top part can be fused and shed by itself in the case of fire; the connection device at the front end part is fused, and the wall panel can fall off.
Further, as shown in fig. 2 a-2 f fig. 3a, 3b, the top portion comprises:
the metal frame 1 is made of metal materials, the thickness t = 1.0-3.0 mm, and the thickness of a zinc layer is 60 g/square meter;
the support 2 is made of metal materials, the thickness t = 1.0-3.0 mm, and the thickness of a zinc layer is 60 g/square meter;
the fusing bolt 3 is made of high polymer materials and has high-temperature fusing property;
the falling framework 4 is made of metal materials, the thickness t = 1.0-3.0 mm, and the thickness of a zinc layer is 60 g/square meter;
the noise reduction plate 5 is made of fiber-free nonmetal sound absorption and insulation materials, natural materials and hard structures, the thickness t =20mm, the noise reduction plate is fused at the temperature of 200-250 ℃ in the plate, and waterproof paint is sprayed on the surface of the noise reduction plate;
wherein, the noise reduction plate 5 is stable and reliable in the whole structure under the non-fire condition and can bear the walking of the operation and maintenance personnel without deformation and fragmentation. At the initial stage of fire (the temperature in the plate is less than or equal to 200 ℃), the noise reduction plate 5 is slowly softened in a continuous high-temperature environment, the rigidity is weakened, and the downward bending state is shown, at the moment, the falling framework 4 and the falling prevention net 8 fall in advance. When a fire disaster enters the middle stage (the temperature inside the plate is 200-250 ℃), the noise reduction plate 5 finally loses rigidity completely along with the continuous rise of the environmental temperature, and can be torn into a plurality of fragments under the action of self weight and fall from a space area created by the falling framework 4 and the falling prevention net 8.
When dropping objects such as equipment, pipeline, etc., the small block can be broken into small fragments, even when dropping to the ground, the small fragments can be broken again, the fragments can be finally presented on the equipment and the ground, the powder state can not form sheltering and covering on the fire ignition point of the equipment, thereby not influencing the covering of the fire truck medium on the flame. Fig. 4 is a schematic diagram showing the top noise reduction plate 5 being fused.
The standard matching framework 6 is made of metal materials, the thickness t = 1.0-3.0 mm, and the thickness of a zinc layer is 60 g/square meter;
the cushion block 7 is made of metal materials or high polymer materials;
the falling prevention net 8 is made of a metal material or a polymer material and is formed by a netted hollow plane;
wherein, 4 both ends that drop are through firm the fixing on standard configuration skeleton 6 and support 2 of fusing bolt 3, and metal frame 1 forms complete whole metal framework, for falling the board 5 that makes an uproar and provide the structure supporting role. The anti-falling net 8 is firmly fixed on the metal frame 1 through the fusing bolt 3.
The anti-falling net 8 plays a role of safety protection under the non-fire condition, the upper-layer structure is prevented from being damaged and falling, and equipment and personnel on the lower layer are protected. When a fire occurs inside, the fusing bolt 3 deforms and softens at high temperature to fuse, the cushion block 7 connected with the fusing bolt loses the pivot and falls off, so that connection points at two ends of the falling framework 4 are damaged, two ends of the falling framework 4 have enough falling gaps, the falling framework 4 firstly falls off, and space conditions are created for the broken and falling fusing of the noise reduction plate 5.
When a fire disaster occurs inside the anti-falling net, the fusing bolt 3 for fixing the anti-falling net 8 is fused by high-temperature deformation (the principle is the same as the principle), and the anti-falling net falls off under the action of the dead weight of the falling net, so that a space condition is created for the fusing, breaking and falling of the noise reduction plate 5.

Meanwhile, when the lower wall panel 9 and the upper wall panel 10 are in the initial stage of a fire (the temperature inside the panel is less than or equal to 200 ℃), the lower wall panel 9 and the upper wall panel 10 are gradually softened in a continuous high-temperature environment, the rigidity is weakened, and the outer side are raised or warped. When the fire disaster enters the middle stage (the temperature inside the plate is 200-250 ℃), the lower wall panel 9 and the upper wall panel 10 can finally lose rigidity along with the continuous rise of the environmental temperature, and the lower wall panel and the upper wall panel can be broken into a plurality of fragments to fall downwards under the action of self weight. In practical engineering application, the falling-off action of the wall panel 9 and the upper wall panel 10 and the downward sliding action are not in sequence, and can occur in tandem or simultaneously, so that the structure is a double-safety structure, and the function of opening the front end part can be realized to the greatest extent.
The fritter can be hit and become tiny fragment when hitting objects such as equipment, pipeline at the in-process that drops, and tiny fragment still can be broken once more when dropping subaerially even, finally can present the disintegrating slag on equipment and subaerial, and the powder state can not form sheltering from, covering to equipment conflagration ignition point to can not influence the operation of putting out a fire of fire engine, the fire engine can be accurate put out a fire to the flame root. Greatly improving the accuracy and efficiency of fire extinguishing. Fig. 7 is a schematic view showing the front end portion of the lower wall panel 9 and the upper wall panel 10 fused.
