[0027] Example 1

[0028] like Figure 1-Figure 6 As shown,

[0029] A flame retardant performance detection device for a building wall comprises a combustion detection box 1. The top of the combustion detection box 1 is a transparent observation window 101, through which the combustion situation in the combustion detection box 1 can be conveniently observed.

[0030] The combustion detection box 1 is internally slidably connected with a sliding frame 8, which can slide back and forth inside the combustion detection box 1. Two fixing seats 9 are installed in the middle of the top end surface of the sliding frame 8, and a flamethrower can be installed through the fixing seats 9.

[0031] Specifically, a fixing plate 901 is hinged on the top of the fixing seat 9, and a heat-insulating lining plate 10 is installed in the inner side walls of the fixing seat 9 and the fixing plate 901. The flamethrower can be fixed by clamping the flamethrower on the fixing seat 9 and then closing the fixing plate 901 by locking.

[0032] The guide rails 102 are symmetrically arranged in the middle of the left and right inner walls of the combustion detection box 1, and a bottom guide groove 103 is provided in the middle of the bottom of the combustion detection box 1. The sliding frame 8 is in a T-shaped structure, and a cylindrical hand-operated lever 801 is fixedly installed in the middle of the front side of the sliding frame 8. The bottom of the sliding frame 8 is rotatably connected with a ball 802, and the ball 802 is rotatably connected in the bottom guide groove 103. The tops of the left and right side walls of the sliding frame 8 are both rotatably connected with two rollers 803, and the bottoms of the rollers 803 are slidably connected to the tops of the guide rails 102. The sliding position of the sliding frame 8 inside the combustion detection box 1 can be controlled by the hand-operated lever 801, so as to control the distance between the flamethrower and the wall of the building to be detected according to the detection needs. Through the cooperation of the roller 803 and the ball 802, the movement of the sliding frame 8 is smoother and smoother, and the control is more convenient.

[0033] Flame extinguishing holes 105 are provided at a medium distance on the left and right inner walls of the combustion detection box 1. Cone-shaped circular plates 106 are arranged at a medium distance on the flame extinguishing holes 105. The inner walls of the circular plates 106 are inclined, and there are gaps between adjacent circular plates 106. A flame guide port 107 with an opening facing downward is provided at the corresponding position on the outer side of the flame extinguishing hole 105. By providing the flame extinguishing holes 105 at a medium distance on the inner wall of the combustion detection box 1, the flame retardancy test of the building wall surface can be carried out by flame, and the overflowing flame is discharged through the flame extinguishing holes 105, and the circular plates 106 arranged inside the flame extinguishing holes 105 and the gaps between the circular plates 106 are formed to block the flame, so as to consume the flame faster and avoid the harm caused by the flame spreading. In addition, a flame guide port 107 is provided on the outer side of the flame extinguishing hole 105, and the flame guide port 107 facing downward can better reduce the danger.

[0034] Since the flame is continuous during detection, flames will continue to be generated, which can easily cause the temperature of the side wall of the device to rise, and people are very likely to get burned when they touch it, which is very dangerous. Therefore, in this embodiment, two rectangular firebreaks 2 are symmetrically installed on the rear side of the left and right outer walls of the combustion detection box 1, and a cooling channel 201 with a U-shaped cross-section is opened inside the firebreak 2. The cooling channel 201 is connected to the flame guide port 107 of the combustion detection box 1. By wrapping the firebreak 2 on the outside of the flame guide port 107 on the outside of the combustion detection box 1, the high temperature generated by the flame combustion can be better isolated and the destructiveness can be reduced. The flame and high-temperature smoke discharged from the flame guide port 107 are cooled by the cooling channel 201 and discharged from the top of the firebreak 2.

[0035] In order to cool down the firebreak 2, the outer wall of the cooling channel 201 is provided with a hollow heat dissipation cavity, a filling hole 202 is opened on the top of the heat dissipation cavity of the firebreak 2, a sealing plug 5 is threadedly connected in the filling hole 202, the interior of the heat dissipation cavity is filled with heat dissipation liquid, and a cooling pipe 7 is provided on the rear side of the combustion detection box 1. Through the circulation cooperation between the firebreak 2 and the cooling pipe 7, high temperature can be avoided in the firebreak 2, and scalding of personnel can be prevented during detection.

[0036] Specifically, the left and right sides of the bottom of the cooling pipe 7 are water outlets, and interfaces are respectively provided at the top and bottom of the firebreak 2, which are connected to the heat dissipation cavity of the firebreak 2, and the water outlets are connected to the interfaces at the bottom of the two rear side walls of the firebreak 2. The left and right sides of the top of the cooling pipe 7 are water return ends, which are connected to the interfaces at the top of the rear side walls of the firebreak 2, thereby realizing the connection between the cooling pipe 7 and the heat dissipation cavity of the firebreak 2. A circulation pump 701 is fixedly installed at the middle of the bottom of the cooling pipe 7, and the circulation pump 701 realizes the circulation of the heat dissipation liquid (water) in the heat dissipation cavity of the cooling pipe 7 and the firebreak 2.

[0037] In order to improve the heat dissipation of the heat dissipating liquid in the cooling pipe 7, a cooling fan 6 is fixedly installed on the rear side of the combustion detection box 1, and the cooling fan 6 is used to cool the heat dissipating liquid.

[0038] Specifically, side uprights 3 are fixedly installed on the left and right sides of the rear side wall of the combustion detection box 1, a center column 4 is fixedly installed in the middle of the rear side wall of the combustion detection box 1, and a cooling fan 6 is fixedly installed between the side uprights 3 and the center column 4. By connecting the water outlet and return water ends of the cooling pipe 7 to the bottom and top of the rear side walls of the two firebreaks 2 respectively, the heat dissipation liquid inside the firebreak 2 can be recycled, and the cooling fan 6 on the rear side of the cooling pipe 7 is used to cool the heat dissipation liquid, thereby improving the utilization efficiency and increasing the reliability of the device during detection.

[0039] When the utility model is in use:

[0040] First, fix the building wall to be inspected in the combustion detection box 1, then clamp the flamethrower on the fixing seat 9, and fix the flamethrower by closing the fixing buckle plate 901; then, the sliding position of the sliding frame 8 inside the combustion detection box 1 can be controlled by the hand control rod 801, so as to control the distance between the flamethrower and the building wall to be inspected according to the detection needs. At this time, the cooperation of the roller 803 and the ball 802 makes the movement of the sliding frame 8 smoother and more convenient to control;

[0041] The spilled flame is discharged through the flame extinguishing hole 105, and passes through the circular plates 106 arranged inside the flame extinguishing hole 105 and the gaps between the circular plates 106 to block the flame, so as to consume the flame more quickly and avoid the harm caused by the spilled flame;

[0042] By wrapping the firebreak 2 on the outside of the flame guide port 107 on the outside of the combustion detection box 1, the high temperature generated by the flame combustion can be better isolated and the destructiveness can be reduced. By connecting the water outlet and return ends of the cooling pipe 7 to the bottom and top of the rear side walls of the two firebreaks 2 respectively, the heat dissipation liquid inside the firebreak 2 can be recycled, and the cooling operation of the heat dissipation liquid can be performed by the cooling fan 6 on the rear side of the cooling pipe 7.

[0043] The utility model opens flame extinguishing holes at medium distances on the inner wall of the combustion detection box so that the flame retardancy test of the building wall can be carried out through the flame extinguishing holes, and the overflowing flame is discharged through the flame extinguishing holes, and the round-shaped plates arranged inside the flame extinguishing holes and the gaps between the round-shaped plates are used to block the flame, so that the flame can be consumed more quickly and the harm caused by the flame overflow can be avoided. In addition, a flame guide port is provided on the outer side of the flame extinguishing hole, and the flame guide port is downward to better reduce the danger.

[0044] The utility model can better isolate the high temperature generated by flame combustion and reduce destructiveness by wrapping the firebreak on the outside of the flame guide port on the outside of the combustion detection box, and the side wall of the firebreak is hollow and filled with heat dissipation liquid. By cooperating with the circulation of the cooling pipe, high temperature can be avoided in the firebreak, and scalding of personnel during detection can be prevented. The heat dissipation liquid in the firebreak can be recycled by connecting the water outlet and return ends of the cooling pipe to the bottom and top of the rear side walls of the two firebreaks respectively, and the cooling operation of the heat dissipation liquid is performed by the cooling fan on the rear side of the cooling pipe, thereby improving the utilization efficiency and increasing the reliability of the device during detection.
