One end of a spring A nested outside the cylinder B is connected with the tension spring ring, and the other end of the spring A is connected with the inner wall of the shell; the connecting rod B and the supporting rod B axially slide in the guide groove A on the side wall of the cylinder B. The guide groove a prevents the sliding plug from rotating relative to the cylinder a by providing a track for the movement of the support rod B, thereby providing a track for the axial movement of the crown block within the housing. Four guide blocks A are symmetrically arranged on the outer side of the guide seat A, and slide in four guide grooves B on the inner wall of the cylinder B respectively. The matching of the guide block A and the guide groove B plays a role in positioning and guiding the axial movement of the guide seat A in the cylinder B.

Compared with the traditional fire extinguishing mode of the outer wall heat-insulating layer, the fire extinguishing mode of the invention is that the building outer wall is buried in the outer wall heat-insulating layer when the heat-insulating layer is installed. When the outer wall heat-insulating layer is in fire disaster due to some accidents, the organic solution in the colored glaze body embedded at the ignition point of the heat-insulating layer expands rapidly, so that the colored glaze body is cracked, the sliding plug slides outwards and axially under the action of the spring A in stretching energy storage and drives the ball body of the outer sleeve B to be separated from the spherical hole on the shell through a series of transmission, so that the spherical hole is opened, and water in the shell is sprayed or leaked to the heat-insulating layer wrapping the shell through the opened spherical hole, thereby achieving the effect of gradually extinguishing the fire. Meanwhile, the movement of the outer sleeve A embedded at the ignition point causes the deflector rod arranged on the ball body to pull a plurality of steel wire ropes A connected with the periphery of the ball body, so as to drive the deflector rods in the periphery of the ball body to swing towards the ignition point. The swinging deflector rod drives the ball body on the corresponding outer sleeve A to rotate relative to the inner wall of the spherical hole on the corresponding shell, so that part of the water permeable holes B on the ball body on the outer sleeve A are separated from the inner wall of the spherical hole and exposed. Meanwhile, the distance is reserved between the sphere center of the concave spherical surface B and the sphere center of the sphere, so that the rotating outer sleeve A drives the outer sleeve B which is in rotating fit with the rotating outer sleeve A to synchronously swing around the sphere center of the sphere on the outer sleeve A, and the distance between the sphere center of the concave spherical surface B in the outer sleeve A and the sliding block A is increased. The outer sleeve A can swing in a self-adaptive mode relative to the outer sleeve B under the action of the blocking column, the sliding block A or the guide seat B can move in a self-adaptive radial mode relative to the guide seat A under the driving of the blocking column, and the blocking column slides outwards relative to the outer sleeve A. The hole A of permeating water on the overcoat is opened, and the water that is located the shell is through the clearance between stifled post and the overcoat A, the hole A of permeating water, indent sphere C and the partial hole B of permeating water to its heat preservation on every side infiltration humidification, prevents the further stretching of the ignition potential of a fire, reduces the further destruction of conflagration to outer wall heat preservation.
In addition, the deflector rod of the jacket B at the ignition point can swing part of the water permeable holes B on the jacket B out of the spherical surface holes only by small-angle deflection under the pulling of the steel wire rope A, so that the outward water permeable channels distributed around the ignition point are quickly opened, and the effect of timely and quickly extinguishing fire or humidifying the heat preservation layer is achieved. Meanwhile, the sphere in the outer sleeve B is in rotating fit with the inner wall of the spherical hole in the shell, so that no matter which direction or angle the outer sleeve B rotates relative to the shell, a contact ring is properly formed between the sphere on the outer sleeve B and the inner wall of the spherical hole in the shell, and good sealing performance of the contact ring is guaranteed. Meanwhile, the thickness of the side wall where the spherical hole is located is larger, so that the matching area between the sphere in the outer sleeve B and the inner wall of the spherical hole is larger, and the sealing performance between the sphere in the outer sleeve B and the inner wall of the spherical hole is effectively improved. The invention has simple structure and better use effect.

As shown in fig. 15, two adjacent connection bars B52 of the present invention are connected by a wire rope a48, a water passage a2 of the present invention housing 1 is connected to a water passage B3 of the adjacent housing 1 of the present invention by a connection water pipe 57, and a water passage B3 of the housing 1 is connected to a water passage a2 of the adjacent housing 1 of the present invention by a connection water pipe 57. The water through ports B3 on the endmost shell 1 of the present invention are blocked off in a straight line connected by the connecting water pipe 57. The invention is connected with a plurality of water headers 56 which are made of metal and are embedded in the heat preservation layer through the metal connecting water pipes 57 and are arranged on a straight line.
The spring D51 in a compressed state drives the outer sleeve B38 to press and plug the spherical hole 5 on the shell 1 through the slider B50, the connecting rod B52, the guide seat A19, the guide seat B21, the slider A25, the connecting rod A29, the plug column 30 and the outer sleeve A33.
The invention is buried in the outer wall heat-insulating layer.
The working process of the invention is as follows: in an initial state, the spring D51 in a compressed state drives the blocking column 30 to block the water-permeable hole a37 on the jacket a33 through the slider B50, the connecting rod B52, the guide seat a19, the guide seat B21, the slider a25 and the connecting rod a29, and the jacket a33 drives the jacket B38 to block the spherical hole 5 on the shell 1 under the pushing of the blocking column 30. The water permeable holes B44 on the outer sleeve B38 are blocked by the inner wall of the spherical hole 5. The ends of the cylinders 59 on the jacket B38 are located within the interior tapers 18 on the cylinder B15. Spring A14 is in tension and spring B24, spring C27, and spring D51 are in compression. The pulling condition of the deflector rod 46 is the same for a plurality of deflector rods 46 distributed around through a plurality of steel wire ropes A48, and the steel wire rope A48 is in a tension-free state. The wire rope B55 is in a taut state. The guide block a28 is located at the extreme position of the corresponding guide slot B58, with the guide seat a19 being the farthest from the slide plug 9. Guide seat B21 is located at a central position within guide seat a19 and slide a25 is located at a central position within guide seat B21.
When the heat insulation layer at a certain part of the outer wall catches fire, the colored glaze body 8 on the fire part is quickly heated, the organic solution in the colored glaze body 8 is quickly expanded, the colored glaze body 8 is quickly cracked, and the limitation of the sliding plug 9 on the movement into the cylinder A6 is removed. The sliding plug 9 slides axially into the cylinder a6 under the action of a spring a14 in tensile energy storage. The sliding plug 9 drives the fixed pulley 54 to move synchronously through the supporting rod B53, the fixed pulley 54 pulls the sliding block B50 in the guide seat D to move in the same direction through the steel wire rope B55, and the spring D51 is further compressed to store energy. Since the moving speed of the fixed pulley 54 is equal to half of the moving speed of the sliding block B50, the sliding block B50 can drive the outer sleeve B38 to open the spherical hole 5 on the outer shell 1 sufficiently quickly and sufficiently through a series of transmission while the moving distance of the cylinder a6 is small, so that the water in the outer shell 1 can extinguish the fire through the rapidly and sufficiently opened spherical hole 5.
The sliding block B50 drives the guide seat A19 to move axially relative to the cylinder B15 through the connecting rod B52, the guide seat A19 drives the guide seat B21 which slides in the radial direction to move synchronously, and the guide seat B21 drives the sliding block A25 which slides in the radial direction to move synchronously. The sliding block A25 drives the blocking column 30 to move axially outwards relative to the outer sleeve A33 through the connecting rod A29, and four guide blocks D32 mounted on the blocking column 30 axially slide in corresponding guide grooves E35. The convex spherical surface A31 at the end of the blocking column 30 is separated from the concave spherical surface A36 inside the jacket A33 and opens the water permeable hole A37 on the jacket A33. The movement of the stem 30 releases the compression of the sleeve a33 compressed by the stem 30 and the sleeve B38 compressed by the sleeve a 33.
When the four guide blocks D32 move to the limit position of the corresponding guide groove E35, the continuously moving blocking column 30 drives the sleeve B38 to be separated from the spherical hole 5 on the shell 1 through the four guide blocks D32 and the sleeve A33, the spherical hole 5 on the shell 1 is opened, and simultaneously all the water permeable holes B44 on the sleeve B38 are completely separated from the blocking of the inner wall of the spherical hole 5 and are communicated with the outside. During the opening of the envelope B38 to the sphere hole 5, the cylinder 59 on the envelope B38 enters the cylinder B15 and is guided for axial movement by the cylinder B15. When water in the shell 1 is sprayed to the heat-insulating layer or flame wrapping the shell 1 through the opened spherical surface holes 5, the water in the shell 1 is sprayed to the external heat-insulating layer through the water-permeable holes A37 on the outer sleeve A33 and all the water-permeable holes B44 on the outer sleeve B38 for fire extinguishment, so that the aim of fixed-point fire extinguishment at a fire point is fulfilled.
The sheath B38 of the present invention, which has been triggered at the fire point, pulls a number of surrounding deflector rods 46 of the present invention through deflector rods 46 and a number of steel cords a48 connected to the surrounding invention. The plurality of inventions triggered by the jackets B38 in the invention at the fire point and distributed around the fire point have the same flow process of the operation inside the plurality of inventions due to the movement of the deflector rod 46, so that the flow process is only described as one of the plurality of inventions distributed around the fire point, and the working flow process is as follows:
when the deflector rod 46 is pulled by the jacket B38 on a fire point through the steel wire rope A48, the deflector rod 46 drives the jacket B38 to rotate around the spherical center of the sphere 39 at a small angle relative to the spherical hole 5 on the corresponding shell 1, and the plurality of water permeable holes B44 on the sphere 39 swing away from the inner wall of the spherical hole 5 and are communicated with the opening of the spherical hole 5. Meanwhile, as the center of the sphere 39 is at a certain distance from the center of the convex spherical surface B45 on the outer sleeve a33, the swinging of the outer sleeve B38 around the center of the sphere 39 drives the outer sleeve a33 connected with the outer sleeve to swing around the center of the sphere 39, so that the distance between the center of the convex spherical surface B45 on the outer sleeve a33 and the sliding plug 9 is increased. And because the outer sleeve A33 is in axial sliding fit with the blocking column 30, the outer sleeve A33 swings around the sphere center of the sphere 39 along with the outer sleeve B38, the outer sleeve A33 swings around the sphere center of the sphere 39 in a self-adaptive mode under the blocking effect, and the blocking column 30 slides outwards in the axial direction relative to the outer sleeve A33. The convex spherical surface A31 at one end of the blocking column 30 is separated from the concave spherical surface A36 in the jacket A33 and opens the water permeable hole A37 on the jacket A33, so that the inside of the shell 1 is communicated with the outside through the water permeable hole A37 on the jacket A33 and the water permeable hole B44 on the inner wall of the spherical hole 5 swung out of the jacket B38. Meanwhile, the outer sleeve A33 drives the sliding block A25 to perform self-adaptive radial sliding in the guide seat B21 through the blocking column 30 and the connecting rod A29, and the guide seat B21 performs self-adaptive radial sliding in the guide seat A19 under the driving of the sliding block A25; two springs C27 are deformed to store energy, and four springs B24 are deformed to store energy.
Water in the shell 1 is to wrapping up the shell 1 and not having the heat preservation infiltration of catching fire through open spherical surface hole 5 simultaneously, and water in the shell 1 still permeates water humidification through the whole holes of permeating water A37 on overcoat A33 and all holes of permeating water B44 on overcoat B38 to the heat preservation that does not catch fire around the ignition, prevents the intensity of a fire of ignition from stretching, improves fire extinguishing efficiency.
In conclusion, the beneficial effects of the invention are as follows: the invention is buried in the outer wall heat-insulating layer when the heat-insulating layer is installed on the outer wall of the building. When the external wall heat-insulating layer is in fire disaster due to some accidents, the organic solution in the colored glaze body 8 embedded at the fire point of the heat-insulating layer expands rapidly, so that the colored glaze body 8 is cracked, the sliding plug 9 slides outwards and axially under the action of the spring A14 in stretching energy storage and drives the sphere 39 of the jacket B38 to be separated from the spherical hole 5 on the shell 1 through a series of transmission, so that the spherical hole 5 is opened, and water in the shell 1 is sprayed or leaked to the heat-insulating layer wrapping the shell 1 through the opened spherical hole 5, thereby achieving the effect of gradually extinguishing the fire. Meanwhile, the movement of the jacket a33 of the present invention embedded at the fire point causes the deflector rod 46 mounted on the sphere 39 to pull the surrounding several steel cables a48 of the present invention, thereby driving the surrounding several deflector rods 46 to swing toward the fire point. The swinging deflector rod 46 drives the ball 39 on the corresponding outer sleeve a33 to rotate relative to the inner wall of the spherical hole 5 on the corresponding shell 1, so that the part of the water permeable holes B44 on the ball 39 on the outer sleeve a33 are separated from the inner wall of the spherical hole 5 and exposed. Meanwhile, as the center of the concave spherical surface B42 is spaced from the center of the spherical body 39, the rotating outer sleeve A33 drives the outer sleeve B38 which is rotationally matched with the outer sleeve A33 to synchronously swing around the center of the spherical body 39 on the outer sleeve A33, so that the distance between the center of the concave spherical surface B42 in the outer sleeve A33 and the sliding block A25 is increased. The outer sleeve A33 can adaptively swing relative to the outer sleeve B38 under the action of the blocking column 30, the sliding block A25 or the guide seat B21 can adaptively and radially translate relative to the guide seat A19 under the driving of the blocking column 30, and the blocking column 30 can outwards slide relative to the outer sleeve A33. The water permeable holes A37 on the outer sleeve are opened, and water in the shell 1 permeates water and humidifies to the surrounding heat-insulating layer through the gap between the blocking column 30 and the outer sleeve A33, the water permeable holes A37, the concave spherical surface C43 and the partial water permeable holes B44, so that the further spread of the ignition intensity is prevented, and the further damage of the fire to the heat-insulating layer of the outer wall is reduced.
In addition, the deflector rod 46 of the jacket B38 at the fire point can swing part of the water permeable holes B44 on the jacket B38 out of the spherical hole 5 only by small-angle deflection under the pulling of the steel wire rope A48, so that the outward water permeable channels distributed around the fire point are quickly opened, and the effect of quickly extinguishing fire or humidifying the heat preservation layer in time is achieved. Meanwhile, because the sphere 39 in the outer sleeve B38 is in rotating fit with the inner wall of the spherical hole 5 on the outer shell 1, no matter what direction or angle the outer sleeve B38 rotates relative to the outer shell 1, a contact ring is properly formed between the sphere 39 on the outer sleeve B38 and the inner wall of the spherical hole 5 on the outer shell 1, and therefore good sealing performance of the spherical hole is guaranteed. Meanwhile, the thickness of the side wall where the spherical hole 5 is located is larger, so that the matching area between the spherical body 39 in the outer sleeve B38 and the inner wall of the spherical hole 5 is larger, and the sealing performance between the spherical body 39 and the inner wall of the spherical hole 5 is effectively improved.
