Since the left end of the elastic sheet 2 is stationary, the elastic sheet 2 is stretched and deformed. As shown in fig. 10, with the stretching deformation of the elastic sheet 2, the lower opening of the first cavity 5 is opened, and the fire extinguishing powder in the first cavity 5 is gradually sprinkled down and falls down to extinguish the fire. As shown in fig. 7, a cavity is disposed inside the connecting body 8, and a driving assembly is disposed inside the cavity. When connecting body 8 slided along spout 10, this drive assembly drives flexure strip 2 through the cooperation with guide way 16 and rotates around rotation axis 4, and then takes place the slope (the final turned angle of flexure strip 2 is less than 90 degrees) for the dry powder of putting out a fire in the second cavity 6 is from the opening part landing of downward one end gradually, falls on the flame of below and puts out a fire.

The elastic sheet 2 is in a wave shape and is in a horizontal state to fill the inner side of the frame 1, so that the flame can be prevented from continuously spreading upwards, and the elastic sheet 2 also has a certain heat insulation effect due to the wave shape. In the prior art, the temperature difference between the inside and the outside of an industrial factory building (which is not subjected to heat preservation treatment) using the wave plates is about 2 ℃, so that the damage of high temperature to objects above the elastic sheets 2 can be reduced as much as possible.

As shown in fig. 7, the driving assembly includes a gear 11, a second slider 13, a first slide bar 14, and a second slide bar 15, the gear 11 is fixedly mounted on the rotating shaft 4, a second slider 13 is slidably connected in a cavity of the connecting body 8, one end of the second slider 13 is fixedly connected with a rack 12 engaged with the gear 11, the other end of the second slider 13 is fixedly connected with the first slide bar 14, one end of the first slide bar 14 sequentially slides through the connecting body 8 and the first slider 9, and is fixedly connected with the second slide bar 15, the second slide bar 15 and the first slide bar 14 are vertically arranged, and the second slide bar 15 is slidably connected with the guide groove 16.

As shown in fig. 12, the guide groove 16 includes a straight section, an inclined section, and a return section. As shown in fig. 1, the connecting body 8 moves to the right while driving the driving assembly to move to the right, when the second slide bar 15 slides in the straight section of the guide slot 16, no relative movement occurs between the driving assembly and the connecting body 8, and when the second slide bar 15 moves to the inclined section of the guide slot 16, the second slide bar 15 is shifted to the inside along the inclined section. As shown in fig. 7, the second slide bar 15 drives the second slide block 13 to slide rightwards in the cavity of the connecting body 8 through the first slide bar 14, the second slide block 13 pushes the rack 12 to move rightwards, the rack 12 moves rightwards to drive the gear 11 to rotate anticlockwise, and further drives the elastic sheet 2 to rotate anticlockwise around the rotating shaft 4 and incline, one end of the elastic sheet 2 gradually moves downwards, so that the fire extinguishing dry powder in the second cavity 6 gradually slides down from an opening at the downward end, and falls on the flame below to extinguish fire. When the second sliding rod 15 moves to the aligning section, the second sliding rod 15 moves outwards under the action of the aligning section, the second sliding rod 15 drives the rack 12 to move leftwards through the first sliding rod 14 and the second sliding block 13, and then the elastic piece 2 is restored to the horizontal state from the inclined state and is fully paved on the whole frame 1, and the flame is prevented from spreading upwards from a gap between the elastic piece 2 and the frame 1.

The trigger member comprises a limit member 17 and a tension spring, the limit member 17 is a rectangular block made of hard PVC with a melting point of about 60 degrees celsius, and the limit member 17 can also be made of other suitable materials with a low melting point. The size and the shape of the limiting piece 17 are matched with the limiting hole 18, and the limiting piece 17 is fixed on the first sliding block 9 and installed in the limiting hole 18. Extension spring one end is fixed with first slider 9, and the extension spring other end is fixed with the inboard that spout 10 deviates from connector 8. In the initial state, the limiting member 17 is located in the limiting hole 18, and the tension spring has elastic potential energy due to being stretched. When a fire disaster happens, the limiting part 17 is melted at high temperature and loses the limiting effect, and the tension spring is reset due to the large elastic potential energy of the tension spring, and drives the first sliding block 9 to slide along the sliding groove 10, so as to drive the connecting body 8, the elastic sheet 2, the first ceiling plate 19 and the second ceiling plate 20 to synchronously move.

The bottom of the elastic sheet 2 is coated with fireproof paint to further prevent flame from spreading upwards.

One side of the top surface of the first ceiling plate 19, which is close to the connector 8, is provided with an avoiding groove 21, so that the connector 8 and the first ceiling plate 19 are prevented from generating movement interference, and the first ceiling plate 19 can be positioned above the elastic sheet 2 in a vertical state.

The sound absorption cotton layers 22 are arranged on the bottom surfaces of the first ceiling plate 19 and the second ceiling plate 20, so that the sound absorption function is realized.

The sliding fit of first slider 9 and spout 10 has certain sliding damping, and such setting can avoid connector 8 to slide to one side fast under the elastic action of extension spring to make flexure strip 2 warp with relatively gentle speed, guarantee the dry powder of putting out a fire in first cavity 5 and the second cavity 6 and evenly scatter gradually.

The initial state of the first ceiling board 19 and the second ceiling board 20 is in a V shape, and the position of the hinge point of the first ceiling board 19 and the second ceiling board 20 is higher than the position of the rotation point of the first ceiling board 19 and the connection body 8 and higher than the position of the rotation point of the second ceiling board 20 and the frame 1, so that the first ceiling board 19 and the second ceiling board 20 do not generate movement interference and are difficult to move.

The working principle is as follows: in an initial state, the elastic sheet 2 does not have elastic potential energy in the state, the elastic sheet 2 slightly inclines, the elastic membrane 7 is located at the lower end of the elastic sheet 2 when the elastic sheet 2 inclines, the lower opening of the first cavity 5 and the upper opening of the second cavity 6 are in a closed state, and a large amount of fire extinguishing dry powder is contained in the first cavity 5 and the second cavity 6. The limiting member 17 is fixed in the limiting hole 18, the tension spring is stretched to have elastic potential energy, the second slide bar 15 is positioned at the straight section of the guide groove 16, and the first ceiling plate 19 and the second ceiling plate 20 are positioned in the frame 1 in a V shape.

When a fire breaks out, the indoor temperature rises, the limiting piece 17 is melted and loses the limiting effect, at this time, under the action of the tension spring, the connecting body 8 moves rightwards along the length direction of the sliding groove 10 through the first sliding block 9, and the elastic piece 2, the second sliding rod 15, the first ceiling plate 19 and the second ceiling plate 20 act synchronously with the connecting body 8.

When the elastic sheet 2 moves rightwards through the connecting body 8, the elastic sheet is gradually stretched and deformed, the lower opening of the first cavity 5 is gradually opened, and the fire extinguishing dry powder in the first cavity 5 gradually scatters from the lower opening and falls on the flame below to extinguish fire. The upper opening of the second chamber 6 is gradually opened, but the dry powder therein is not slid down due to the stretching of the elastic sheet 2. When the elastic sheet 2 moves to the rightmost end, the elastic sheet 2 undulates and spreads over the entire inner side of the frame 1.

When the elastic piece 2 moves rightwards through the connecting body 8, under the action of the connecting body 8, when the second sliding rod 15 moves in a straight section of the guide groove 16, no relative motion is generated between the second sliding rod 15 and the connecting body 8, when the second sliding rod 15 moves in an inclined section of the guide groove 16, the second sliding rod 15 deflects towards the inner side, the second sliding rod 15 drives the rack 12 to move through the first sliding rod 14 and the second sliding block 13, the driving gear 11 rotates anticlockwise, the gear 11 drives the elastic piece 2 to rotate anticlockwise, so that one end, without the elastic membrane 7, of the elastic piece 2 gradually moves downwards, one end, without the elastic membrane 7, of the elastic membrane 7 gradually moves upwards, the elastic piece 2 gradually becomes inclined, and the fire extinguishing dry powder in the second cavity 6 gradually slides down from one end, and falls on the flame below to extinguish the fire. When the second slide bar 15 moves from the inclined section to the return section, the second slide bar 15 is biased outwards by the return section. The second sliding rod 15 drives the rack 12 to move through the first sliding rod 14 and the second sliding block 13, so that the elastic piece 2 rotates clockwise, the elastic piece 2 is restored to a horizontal state from an inclined state, and the whole frame 1 is paved.

When the first ceiling plate 19 and the second ceiling plate 20 move along with the movement of the connection body 8, the included angle between the first ceiling plate 19 and the second ceiling plate 20 becomes gradually smaller. When the connecting body 8 moves to the rightmost end, the bottom surfaces of the first ceiling plate 19 and the second ceiling plate 20 (i.e., the two sound-absorbing cotton layers 22) are closely attached and positioned above the elastic sheet 2, so that the first ceiling plate 19, the second ceiling plate 20 and the sound-absorbing cotton layers 22 are prevented from directly contacting flames.
