Compared with the traditional fire extinguishing mode of the outer wall heat-insulating layer, the fire extinguishing device disclosed by the invention can automatically extinguish fire when the outer wall heat-insulating layer catches fire in a mode of being embedded in the wall heat-insulating layer in advance. The invention triggers the separation of the ball body on the outer sleeve B and the inner wall of the spherical hole on the shell by the damage of the organic solution in the colored glaze body to the colored glaze body through thermal expansion, thereby quickly opening the channel inside and outside the shell under the condition that the buried part of the invention catches fire, spraying water to the heat-insulating layer wrapped by the invention through the spherical hole in the shell, and achieving the purpose of automatic fire extinguishing.

Water in the shell is sprayed to and humidifies the surrounding heat-insulating layer through the gap between the blocking column and the outer sleeve A, the water-permeable holes A and the partial water-permeable holes B, so that the fire is prevented from spreading to the periphery, and the fire extinguishing speed and efficiency of the fire are accelerated.
In addition, the water permeable holes B on the ball body can get rid of the shielding of the inner wall of the corresponding spherical hole only by swinging a small angle, so that the outward water spraying speed of the water spraying device is increased. The spherical hole and the sphere are rotationally matched due to the structural characteristics, so that the contact area between the inner wall of the spherical hole and the sphere is increased, and the sealing performance of the sphere and the spherical hole in contact is improved. The invention has simple structure and better use effect.

The center of the end face of the top block 11 is provided with a hexagonal groove 13 matched with a hexagonal wrench.
As shown in fig. 6, three L-shaped support rods 14 are axially and uniformly mounted on the end face of the sliding plug 7, and a tension spring ring 15 having the same central axis as the cylinder a6 is mounted at the end of each of the three support rods 14; as shown in fig. 2, 3 and 6, the pulling spring 16 nested on the cylinder B17 is an extension spring; one end of the extension spring is connected with the tension spring ring 15, and the other end is connected with the inner wall of the shell 1.
As shown in fig. 3 and 5, the side wall of the cylinder B17 is provided with three guide grooves a18 which are uniformly distributed in the circumferential direction, and the three support rods 14 axially slide in the three guide grooves a18 respectively; the wall of the cylinder B17 is uniformly provided with a plurality of water permeable grooves 19 which allow running water to pass through; as shown in fig. 3 and 6, four guide blocks 24 are symmetrically mounted on the blocking column 22, and the four guide blocks 24 axially slide in four guide grooves B28 on the inner wall of the circular groove a27 respectively. The cooperation of the guide groove a18 with the support bar 14 ensures the axial sliding of the sliding plug 7 within the cylinder a6 without circumferential rotation relative to the cylinder a6, thereby avoiding damage to the three leaf springs 25 caused by rotation of the sliding plug 7 relative to the cylinder a 6.
As shown in fig. 3, 5 and 9, the end of the cylinder B17 is provided with an internal taper 20, the internal taper 20 cooperating with an external taper 37 at the end of the cylinder on the outer sleeve B31 to guide the cylinder of the outer sleeve B31 smoothly into the cylinder B17.
As shown in FIG. 10, two adjacent connection bars B38 of the present invention are connected by a wire rope 40, a water passage A2 of the present invention case 1 is connected to a water passage B3 of the case 1 of the present invention on one side adjacent thereto by a metal connection pipe 42, and a water passage B3 of the case 1 of the present invention is connected to a water passage A2 of the case 1 of the present invention on the other side adjacent thereto by a metal connection pipe 42. The water through ports B3 on the endmost shell 1 of the invention are sealed off in a straight line connected by the metal connecting water pipe 42. A plurality of the invention which are connected through the metal connecting water pipes 42 and are positioned on a straight line are communicated with the metal water main 41 buried in the heat preservation layer through the metal connecting water pipes 42.
The top block 11 in threaded fit with the inner wall of the cylinder A6 drives the outer sleeve B31 to jack and close the spherical hole 5 on the outer shell 1 through the colored glaze 10, the sliding plug 7, the connecting rod A21, the blocking column 22 and the outer sleeve A26.
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 connecting rod a21 is in a horizontal state under the supporting action of the three plate springs 25, the sliding plug 7 drives the blocking column 22 to block the water permeable hole a30 on the outer sleeve a26 through the connecting rod a21 perpendicular to the sliding plug, and the outer sleeve a26 drives the outer sleeve B31 to block the spherical hole 5 on the shell 1 under the pushing of the blocking column 22. The water permeable holes B36 on the outer sleeve B31 are blocked by the inner wall of the spherical hole 5. The ends of the cylinders on jacket B31 are located within the interior taper 20 on cylinder B17. The pull spring 16 is in tension. The connection rod B38 has the same pulling condition of a plurality of connection rods B38 distributed around through a plurality of steel wire ropes 40, and the steel wire ropes 40 are in a tension state without exerting force.
When the heat insulation layer at a certain part of the outer wall catches fire, the colored glaze body 10 on the fire part is quickly heated, the organic solution in the colored glaze body 10 is quickly expanded, the colored glaze body 10 is quickly cracked, and the limitation of the sliding plug 7 on the movement into the cylinder A6 is removed. The sliding plug 7 slides axially into the cylinder a6 under the action of the pulling spring 16 which is in tension energy storage. The sliding plug 7 drives the blocking column 22 to move towards the outside of the outer sleeve A26 relative to the outer sleeve A26 through a connecting rod A21 which is in spherical hinge connection with the sliding plug, four guide blocks 24 which are installed on the blocking column 22 slide in four guide grooves B28 which are arranged on the inner portion of the outer sleeve, a convex spherical surface A23 at the tail end of the blocking column 22 is separated from a concave spherical surface A29 which is arranged on the inner portion of the outer sleeve A26 and opens a water-permeable hole A30 which is arranged on the outer sleeve A26, and the pressing of the outer sleeve A26 pressed by the blocking column 22 and the pressing of the outer sleeve B31 pressed by the outer sleeve A26 are.
When the four guide blocks 24 move to the limit positions of the corresponding guide grooves B28, the continuously moving blocking column 22 drives the outer sleeve B31 to be separated from the spherical hole 5 on the outer shell 1 through the four guide blocks 24 and the outer sleeve A26, the spherical hole 5 on the outer shell 1 is opened, and simultaneously, all the water permeable holes B36 on the outer sleeve B31 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 B31 to the sphere hole 5, the cylinder on the envelope B31 enters the cylinder B17 and is guided for axial movement by the cylinder B17. 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 A30 on the outer sleeve A26 and all the water-permeable holes B36 on the outer sleeve B31 for fire extinguishment, so that the aim of fixed-point fire extinguishment at a fire point is fulfilled.
The jacket B31 of the invention that has been triggered at the fire point pulls the surrounding several tie bars B38 of the invention through the tie bar B38 and several wire ropes 40 connected to the surrounding invention. The invention triggered by the jacket B31 at the fire point and distributed around has the same flow process of the operation inside due to the movement of the connecting rod B38, so the flow process is only explained as one of the invention distributed around the fire point, and the working flow is as follows:
when the connecting rod B38 is pulled by the jacket B31 of a fire point through the steel wire rope 40, the connecting rod B38 drives the jacket B31 to rotate around the spherical center of the sphere 4432 at a small angle relative to the spherical hole 5 on the corresponding shell 1, and the plurality of water permeable holes B36 on the sphere 4432 swing away from the inner wall of the spherical hole 5 and are communicated with the hole opening of the spherical hole 5. Meanwhile, as the center of the sphere 4432 is at a certain distance from the center of the convex spherical surface B43 on the outer sleeve a26, the swinging of the outer sleeve B31 around the center of the sphere 4432 drives the outer sleeve a26 connected with the sphere hinge to swing around the center of the sphere 4432, so that the distance between the center of the convex spherical surface B43 on the outer sleeve a26 and the sliding plug 7 is increased. And because the outer sleeve A26 is in axial sliding fit with the blocking column 22, and the connecting rod A21 is in spherical hinge connection with the sliding plug 7, the outer sleeve A26 swings around the spherical center of the spherical body 4432 along with the outer sleeve B31, meanwhile, the outer sleeve A26 swings around the spherical center of the spherical body 4432 in a self-adaptive mode under the blocking effect, and the blocking column 22 slides outwards in the axial direction relative to the outer sleeve A26. The convex spherical surface A23 at one end of the blocking column 22 is separated from the concave spherical surface A29 in the jacket A26 and opens the water permeable hole A30 on the jacket A26, so that the inside of the shell 1 is communicated with the outside through the water permeable hole A30 on the jacket A26 and the water permeable hole B36 on the inner wall of the spherical hole 5 swung out of the jacket B31. Meanwhile, the outer sleeve A26 drives the connecting rod A21 to perform self-adaptive swing around the intersection point of the connecting rod and the sliding plug 7 through the blocking column 22, and the three plate springs 25 generate deformation of different degrees.
The water in the shell 1 is in the time of the heat preservation of parcel shell 1 carried out the infiltration through open spherical surface hole 5, and the water in the shell 1 still permeates water humidification through the whole holes of permeating water A30 on overcoat A26 and the holes of permeating water B36 on overcoat B31 around the ignition to the heat preservation that does not catch fire, 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 automatically extinguishes fire when the outer wall heat-insulating layer catches fire by embedding the fire-insulating layer in the wall heat-insulating layer in advance. The organic solution in the colored glaze body 10 is heated and expanded to destroy the colored glaze body 10 to trigger the separation of the sphere 4432 on the outer sleeve B31 and the inner wall of the spherical hole 5 on the shell 1, so that the channel between the inside and the outside of the shell 1 is quickly opened under the condition that the buried part of the invention catches fire, the water in the shell 1 is sprayed to the heat insulation layer wrapping the invention through the spherical hole 5, and the aim of automatic fire extinguishing is achieved.
Meanwhile, in the process of opening the spherical hole 5 in the invention at the fire point, the movement of the sphere 4432 on the outer sleeve B31 pulls a plurality of steel wire ropes 40 connected with the invention at the periphery through corresponding connecting rods B38, the steel wire ropes 40 pull a plurality of connecting rods B38 in the invention distributed at the periphery of the fire point, and the spheres 4432 distributed at the periphery of the fire point through a series of driving belts rotate relative to the spherical hole 5 on the corresponding shell 1, and partial water permeable holes B36 on the sphere 4432 of the outer sleeve B31 are free from the shielding of the inner wall of the spherical hole 5. A plurality of the jackets B31 distributed around the ignition point drive the corresponding jackets A26 to synchronously swing around the spherical center of the sphere 4432, so that the distance between the spherical center of the concave spherical surface A29 on the jacket A26 and the sliding plug 7 is increased. Since the connecting rod A21 is fixedly connected with the blocking column 22, the blocking column 22 slides axially relative to the outer sleeve A26 during the self-adaptive swinging process around the ball hinge point of the connecting rod A21 and the sliding plug 7, and the convex spherical surface A23 of the blocking column 22 quickly separates from the concave spherical surface A29 of the outer sleeve A26 and opens the water-permeable hole A30 on the outer sleeve A26. Water in the shell 1 is sprayed to and humidifies the surrounding heat insulation layer through the gap between the blocking column 22 and the outer sleeve A26, the water permeable holes A30 and the partial water permeable holes B36, the fire ignition force is prevented from spreading to the periphery, and the fire extinguishing speed and efficiency of the fire ignition point are increased.
In addition, the water permeable holes B36 on the spherical surface 4432 can get rid of the shielding of the inner wall of the corresponding spherical surface holes 5 only by swinging a small angle, thereby accelerating the outward water spraying speed of the invention. The resulting structural feature of the rotation fit between the spherical hole 5 and the spherical ball 4432 increases the contact area between the inner wall of the spherical hole 5 and the spherical ball 4432, thereby improving the sealing performance between the spherical ball 4432 and the spherical hole 5.
