Description

Technical Field

[0001] The utility model relates to the technical field of fire doors, in particular to a fire prevention and smoke prevention safety household door fire test device. Background Technique

[0002] A fire prevention and smoke prevention safety household door is a special type of door designed to prevent the spread of fire and the intrusion of smoke to protect the safety of residents. The fire test of a fire prevention and smoke prevention safety household door mainly focuses on testing its integrity and heat insulation. In the existing test device, the fire door is installed in the installation hole of the sealing plate, and then the sealing plate is combined with the combustion chamber. A flame is sprayed into the combustion chamber through a flame nozzle, and at the same time, the temperature in the combustion chamber is monitored through a thermocouple rod. A backfire thermocouple is pasted on the back of the door body to monitor the temperature of the backfire surface of the door. After burning for a period of time, the situation of the fire door is observed.

[0003] The existing backfire thermocouple is pasted on the back of the test door body. On the one hand, after burning for a period of time, the viscosity will be affected, resulting in the detachment of the backfire thermocouple. On the other hand, once the fire door burns through, the flame and high-temperature gas will directly act on the thermocouple and its cable, resulting in damage to its performance. Therefore, a fire prevention and smoke prevention safety household door fire test device is needed to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a fire prevention and smoke prevention safety household door fire test device to solve the problems mentioned in the above background technique. That is, the existing backfire thermocouple is pasted on the back of the test door body. On the one hand, after burning for a period of time, the viscosity will be affected, resulting in the detachment of the backfire thermocouple. On the other hand, once the fire door burns through, the flame and high-temperature gas will directly act on the thermocouple and its cable, resulting in damage to its performance.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0008] A damage prevention component, which includes support columns, a first cross bar, a second cross bar, an electric push rod, a hoop and a bolt. There are a total of four support columns, one of which is hinged to the side of the sealing plate. The first cross bar and the second cross bar are welded between the support columns. The bolt is inserted between the two second cross bars. The electric push rod is fixed at one end of the bolt, and the hoop is sleeved on the fixed end of the electric push rod.

[0009] Further, there are multiple sets of the electric push rods, clamps and bolts, which are distributed inside the corresponding positions of the mounting holes.

The flame nozzle is inserted on the side of the combustion furnace, the thermocouple rod inside the furnace is inserted inside the combustion furnace, one side of the back-fire surface thermocouple is fixed on the electric push rod, and the other side is attached to the door body to be tested.

[0011] Further, the thermocouple rod inside the furnace and the back-fire surface thermocouple are connected to the electrical instrument outside through cables.

[0012] Further, a connection component is further included;

[0027] To make the purpose, technical solutions, and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in detail in conjunction with the attached drawings.

[0028] Please refer to Figure 1-2 As shown, this embodiment is a fire and smoke prevention safety household door fire test device, including:

[0029] Fire detection furnace, the fire detection furnace includes a combustion furnace 10, a sealing plate 13, and an installation hole 14. The sealing plate 13 is movably connected to the side of the combustion furnace 10, and the installation hole 14 is opened in the middle of the sealing plate 13;

[0030] The combustion furnace 10 sprays flames to conduct a combustion test on the door body. The sealing plate 13 plays a role in sealing and supporting, and the mounting holes 14 are used for mounting the test door body.

[0031] The anti-damage component includes support columns 20, a first cross bar 21, a second cross bar 22, electric push rods 23, clamps 24, and bolts 25. There are a total of four support columns 20, one of which is hinged to the side of the sealing plate 13. The first cross bar 21 and the second cross bar 22 are welded between the support columns 20. The bolt 25 is inserted between the two second cross bars 22. The electric push rod 23 is fixed at one end of the bolt 25, and the clamp 24 is sleeved on the fixed end of the electric push rod 23.

[0033] There are multiple groups of electric push rods 23, clamps 24, and bolts 25, which are distributed inside the corresponding positions of the mounting holes 14.

[0034] The fire detection furnace further includes a flame nozzle 11, a thermocouple rod 12 inside the furnace, and a back-fire surface thermocouple 15. The flame nozzle 11 is inserted on the side of the combustion furnace 10, the thermocouple rod 12 inside the furnace is inserted inside the combustion furnace 10, and one side of the back-fire surface thermocouple 15 is fixed on the electric push rod 23, and the other side is attached to the door body to be tested.

[0035] The flame nozzle 11 is connected to an external flame spraying device and can adjust the size of the fire. The thermocouple rod 12 inside the furnace can monitor the temperature inside the combustion furnace 10, and the back-fire surface thermocouple 15 is used to monitor the temperature on the back of the door body.

[0036] The thermocouple rod 12 inside the furnace and the back-fire surface thermocouple 15 are connected to an external electrical instrument through cables.

[0037] Working principle:

[0038] Fix the back-fire surface thermocouple 15 at the movable end of the electric push rod 23. The cable is clamped on the fixed end of the electric push rod 23 with the clamp 24, and reserve the required length of the cable when the electric push rod 23 extends. Move the bolt 25 along the second cross bar 22 to drive the electric push rod 23 and the back-fire surface thermocouple 15 to move to a suitable position, and tighten the bolt 25. During the test, start the electric push rod 23 to drive the back-fire surface thermocouple 15 to move and press tightly against the back of the test door body. When the staff observes that the door body is burned through or observes that the temperature on the electrical instrument exceeds the maximum value, the electric push rod 23 can be started, and the electric push rod 23 contracts to drive the back-fire surface thermocouple 15 away from the door body.

[0039] This step can reduce the probability of damage to the back-fire surface thermocouple 15 and the cable due to high temperature.

[0040] Please refer toFigure 3 , on the basis of the above embodiments, this embodiment further includes:

[0045] The adjusting rod 33 serves as a connection function, the rotating wheel 34 facilitates the hand to operate the adjusting rod 33, and the bearing 35 facilitates the rotation of the adjusting rod 33.

[0046] Working principle:

[0047] After combustion ends, it is necessary to check whether the fire door can maintain its structural integrity and then judge its smoke isolation performance. At this time, the rotating wheel 34 can be rotated to make the adjusting rod 33 rotate in the bearing 35. At the same time, one end of the adjusting rod 33 rotates out of the groove 32 of the connecting block 31, pulling the rotating wheel 34 to drive the adjusting rod 33 to move, and further driving the connecting column 30 to move, so that the electric push rod 23 and the back-fire surface thermocouple 15 on the second cross bar 22 flip and move away from the door body, and then the high-pressure water gun can be opened to spray the door body.

[0048] This step facilitates the later integrity test. At the same time, the anti-damage component can be fixed by the relatively long adjusting rod 33, reducing the harm to the staff when it needs to be opened.
