Description

Technical Field

[0001] The invention relates to the technical field of fireproof material processing, in particular to a fireproof and flame-retardant simulation platform. Background Art

[0002] Fire is a serious hazard. Whether in the field of construction, transportation or industrial production, fire will cause huge losses to life, property and the environment. This has led to an increase in the demand for fire prevention. The accelerated urbanization process and the widespread use of electronic and electrical equipment have put forward higher requirements for fire prevention. Early fire prevention measures were mostly focused on building structure design and fire-fighting equipment, which had limitations. Traditional building materials and early wire and cable insulation materials were flammable and had many problems. In the early 20th century, chemical treatment methods to improve the fire resistance of materials were explored, but the effect was limited. In the mid-20th century, inorganic flame retardants were studied and applied. In the late 20th century, organic flame retardants emerged. Although halogen flame retardants are highly efficient, they have environmental problems, which has led to the development of phosphorus flame retardants. In the 21st century, composite flame retardant technology has become a hot topic, such as the emergence of intumescent fire-retardant materials and new fireproof boards.

[0003] In the prior art, the simulated detection of fire retardancy uses a handheld flamethrower to ignite a local area of ​​the material for detection. This detection method is difficult to accurately control the flame intensity, and the flame stability is also poor. The clamping position of the detection plate will block the flame, and it is impossible to fully reflect the flame retardant performance of the material in a large-scale fire. This may lead to an overestimation or underestimation of the fire retardancy of the material. In addition, when using a handheld flamethrower for detection, the operator is directly exposed to the flame and the possible smoke and toxic gas environment. Without sufficient protective measures, the health of the operator will be damaged. Summary of the invention

[0026] Here’s how it works:

[0027] Step 1: The staff places the detection plate in the center on the surface of the rotating bracket 210 on the left and right sides, and controls the controller 4 to start the second electric push rod 216, the fourth electric push rod 225 and the third electric push rod 222. The second electric push rod 216 extends to drive the positioning frame 215 to move inward inside the slot seat 214, so that the positioning frame 215 fits the side wall of the detection plate to clamp and fix it. The fourth electric push rod 225 extends to drive the rotating frame 224 to rotate downward inside the second fixed seat 223, so that the rotating frame 224 drives the top wheel in cooperation with the second mounting plate 226. 227 rotates to the top of the bottom wheel 218, the third electric push rod 222 shortens and drives the second mounting seat 221 to move downward on the outside of the guide rail frame 220, and the second mounting seat 221, under the cooperation of the second fixed seat 223, the rotating frame 224, the second mounting plate 226 and the top wheel 227, makes the docking seat 229 sleeve on the top outside of the first fixed seat 219 and fit each other, the side walls of the docking seat 229 and the first fixed seat 219 fit with the side walls of the detection plate, and the outer side of the lower surface of the top wheel 227 and the outer side of the upper surface of the bottom wheel 218 fit with the upper and lower surfaces of the detection plate;

[0028] Step 2: The staff controls the controller 4 to start. The preset program in the controller 4 controls the first motor 22, the infrared grating 8, the electric door 7, the first electric push rod 211, the three-axis moving module 10, the storage device 6, the flame spray gun 11, the detection camera 9, the ventilation equipment 5 and the second motor 228 to start. The first motor 22 drives the lead screw 23 to rotate, so that the lead screw nut 24 drives the connecting base 25 to move backward under the action of the rotational force of the lead screw 23, so that the connecting base 25 drives the top plate 28 to drive the upper detection plate to the rear side through the electric door 7 to enter the top shell 3 under the limiting action of the limiting slider 27. After the infrared grating 8 detects that the lower plate has passed, it sends a signal to the controller 4, and the sealing door inside the electric door 7 closes downward to seal the front side of the top shell 3. After the top plate 28 moves to the specified position, the first electric push rod 211 extends to drive the rotating bracket 210, so that the rotating bracket 210 is flipped upward to a vertical state on the inner side of the mounting frame 29, and the three-axis moving module 10 The flame spray gun 11 is driven to move in three-axis directions, the storage device 6 supplies the internally stored combustion raw materials to the flame spray gun 11, and the flame spray gun 11 sprays flames to the surface of the test plate to detect the fire retardant effect. The detection camera 9 collects image data of the internal test process and sends the collected data to the controller 4 for storage and display. During the detection test, the ventilation device 5 purifies the air inside the top shell 3 and discharges it, and sucks the external clean air into the top shell 3 to provide combustion oxygen. The second electric push rod 216 adjusts the clamping force of the positioning frame 215 to the inside, and the second motor 228 drives the top wheel 227 to drive the docking seat 229 to rotate, so that the first fixed seat 219 synchronously drives the bottom wheel 218 to rotate under the action of the friction force of the docking seat 229, so that the detection workpiece moves up and down to adjust the position under the cooperation of the bottom wheel 218, the first fixed seat 219, the docking seat 229 and the top wheel 227 to avoid the dead angle of flame spraying due to clamping;

[0029] Step 3: When the staff observes burning on the surface of the inspection workpiece through the inspection camera 9 and the controller 4, the staff controls the controller 4 to start the horizontal moving module 13, the lifting and moving module 14, the electric telescopic rod 19 and the storage device 6. The horizontal moving module 13 drives the lifting and moving module 14 to move horizontally in the left and right directions, and the lifting and moving module 14 drives the bearing seat 16 to move up and down. The electric telescopic rod 19 extends and shortens to drive the second rotating frame 17 to rotate upward or downward on the inner side of the bearing seat 16, so that the second rotating frame 17 adjusts the pitch angle direction of the spray gun 18, and the storage device 6 sprays the fire extinguishing agent stored inside onto the surface of the inspection workpiece through the spray gun 18 to extinguish the fire.
