[0002] The fire test device for thermal insulation materials is a test device used to test the fire resistance and fire resistance of thermal insulation materials under fire conditions. In construction projects, the fire resistance of thermal insulation materials is very important, because the higher their fire resistance, the higher the safety of the building. At the same time, many thermal insulation materials used in construction projects also need to meet the requirements of relevant national standards and regulations. Therefore, professional fire test devices must be used for testing and evaluation.

[0003] After searching a Chinese patent, a fire test device for thermal insulation materials (publication number CN219162083U) was found, which specifically relates to the field of fire testing, including a box, a servo motor is fixedly provided on the top of the box, the output end of the servo motor passes through the top of the box and extends to the inner cavity of the box, an electric telescopic rod is fixedly provided on the output end of the servo motor, a rotating sleeve is fixedly provided on the bottom of the electric telescopic rod, a threaded rod is movably provided inside the rotating sleeve, and clamping devices are provided at both ends of the threaded rod, and the two clamping devices each include a rotating disk, a bolt, two clamping plates, and two clamping cylinders. The utility model clamps the thermal insulation material on the clamping device by providing a clamping device, a threaded rod, and a rotating sleeve, and the rotating sleeve rotates the threaded rod to rotate the clamping device, so that the thermal insulation material can be evenly burned by the flame, which improves the detection effect compared with the prior art.

[0004] The above patent allows the thermal insulation material to be burned evenly by the flame, thereby improving the detection effect. However, when testing inferior thermal insulation materials, the flame will burn the thermal insulation material with poor fireproof effect. If it cannot be extinguished quickly, fire accidents are likely to occur during the test.

[0005] Therefore, it is necessary to invent a test device for fireproof and heat-insulating materials to solve the above problems. Utility Model Content

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a test device for fireproof and heat-insulating materials, comprising a water tank, on which are installed a plurality of groups of connecting frames, the plurality of groups of connecting frames are symmetrically distributed, each group of the connecting frames is provided with a through slot, the interior of the through slot is provided with a support plate, one end of the support plate is fixedly connected with a rotating shaft, the rotating shaft is rotatably connected with the connecting frame, an insulation material body is provided on the outer side of the connecting frame near the support plate, a pressure plate is provided above the insulation material body, a connecting piece is provided on the pressure plate, the pressure plate is connected with a telescopic shaft via the connecting piece, a driving cylinder is installed on one end of the telescopic shaft away from the connecting piece, an end of the connecting frame away from the water tank is fixedly connected with a mounting plate, and the driving cylinder is connected to the mounting plate.

[0008] Preferably, a first bevel gear is fixedly connected to one end of the rotating shaft, and a second bevel gear is meshedly provided on the outer side of the first bevel gear.

[0009] Preferably, a power shaft is fixedly connected to the inner side of the second bevel gear.

[0010] Preferably, a driving motor is installed at one end of the power shaft away from the second bevel gear, and the power shaft is rotationally connected to the driving motor.

[0011] Preferably, a placement rack is fixedly connected to the top of the mounting plate, and a plurality of groups of flamethrowers are plugged into the placement rack, and the plurality of groups of flamethrowers are linearly distributed on the placement rack.

[0012] Preferably, a water outlet pipe is fixedly connected to the lower end of the water tank.

[0013] Preferably, a control valve is installed on the water outlet pipe.

[0014] Technical effects and advantages of the utility model:

[0015] 1. When in use, the utility model can start the driving motor to rotate the power shaft installed on the driving motor, so that the second bevel gear on the power shaft can drive the first bevel gear to rotate, and then drive the rotating shaft inside the first bevel gear to rotate. Because the rotating shaft is fixedly connected to the support plate, the support plate retracted to the inside of the through groove can be rotated and extended, and then the thermal insulation material body is placed on the support plate, and the driving cylinder is started. The telescopic shaft installed on the driving cylinder is pushed outward, and the telescopic shaft drives the pressing plate downward to squeeze and fix the thermal insulation material body through the connecting piece. Then the user removes the flamethrower on the placement rack and operates the flamethrower to spray flames onto the thermal insulation material body to test the fireproof effect of the thermal insulation material body. This manual operation method can better control the position where the flame is sprayed on the thermal insulation material body, thereby improving the test effect;

[0016] 2. When the inferior thermal insulation material body of the utility model is burned after being sprayed with flame, the driving motor can be started again. At this time, the driving motor can be reversed to quickly shrink the support plate to the inside of the through groove. At this time, the bottom of the burning thermal insulation material body has no supporting point, so it will fall directly into the water tank under the action of gravity. The water in the water tank can extinguish the flame burning on the thermal insulation material body. This method can quickly extinguish the flame on the individual inferior thermal insulation material body during the test to avoid test accidents. BRIEF DESCRIPTION OF THE DRAWINGS
