AI Technical Summary
Existing prefabricated buildings have poor fire resistance and low efficiency in preventing the spread of fire, resulting in insufficient building stability and safety.
The thermal expansion component senses the temperature of the inner wall surface of the side wall. When the temperature is too high, the thermal expansion component expands and drives the button to close, activating the flame retardant liquid delivery mechanism to inject flame retardant liquid into the flame retardant inner cavity. Combined with the sprinkler mechanism, the fire extinguishing liquid is sprayed to prevent the fire from spreading.
It effectively prevents the spread of fire, improves the stability and safety of prefabricated buildings, and enables rapid response to fire situations.

[0027] The following is in conjunction with the appendix Figures 1-4 The present invention will be described in further detail, but this is not intended to limit the scope of the present invention.
[0028] like Figure 1 As shown, in one embodiment of this utility model, the prefabricated building with fireproof function includes a top wall 1 and at least two side walls 2. The side walls 2 are arranged around the bottom of the top wall 1. Each side wall 2 has a flame-retardant inner cavity 201 inside. The top of the side wall 2 is provided with a flame-retardant liquid delivery mechanism 3, and the flame-retardant liquid delivery mechanism 3 is connected to the flame-retardant inner cavity 201. The inner surface of the side wall 2 is provided with an expansion driving mechanism 4. The expansion driving mechanism 4 includes a button 41 and a thermal expansion component 42. The thermal expansion component 42 abuts against the inner surface of the side wall 2. The button 41 is connected to the side wall 2 and electrically connected to the flame-retardant liquid delivery mechanism 3. The expansion direction (upward direction) of the thermal expansion component 42 is oriented towards the pressing end of the button 41. There are four side walls 2, which are arranged around the bottom of the top wall 1 at the front, back, left, and right sides. The top of each side wall 2 is connected to the top wall 1 by at least three positioning bolts or positioning steel bars. The flame retardant liquid can be L-13 flame retardant liquid or water-based flame retardant liquid, etc.
[0029] The technical solution of this utility model uses a thermal expansion component to sense the temperature of the inner wall surface of the side wall. When the internal temperature of the prefabricated building is too high, the thermal expansion component will expand due to heat and move towards the pressing end of the button, so that the button is closed and driven, thereby driving the flame retardant liquid delivery mechanism box to inject the corresponding flame retardant liquid into the flame retardant inner cavity. This can, to a certain extent, prevent the continued spread of fire and quickly improve the stability and safety of the prefabricated building.
[0030] Among them, button 41 is a commonly used control electrical component, mainly composed of a button, an actuating contact, a return spring, and a button box. It is often used to connect or disconnect the 'control circuit' (where the current is very small), thereby controlling the operation of the flame-retardant liquid delivery mechanism 3.
[0031] Specifically, in some implementations, such as Figure 1 , 2 As shown in Figure 3, the thermal expansion component 42 includes a corrugated pipe 421, a support pipe 422, and a mounting block 423. The mounting block 423 is connected to the side wall 2. One end of the support pipe 422 is connected to the mounting block 423. The corrugated pipe 421 is sleeved on the outer surface of the support pipe 422. The button 41 is located between the corrugated pipe 421 and the mounting block 423. There are two mounting blocks 423, arranged side-by-side. The two ends of the support pipe 422 are respectively connected to two different mounting blocks 423. Further, the corrugated pipe 422 refers to a tubular elastic sensitive element formed by connecting foldable corrugated sheets along the folding and stretching direction. That is, when the indoor temperature rises slowly, the corrugated pipe 422 expands due to heat, and the entire structure of the corrugated pipe 422 moves upward until it presses the button 41, thereby driving the flame-retardant liquid delivery mechanism 3.
[0032] Specifically, in some implementations, such as Figure 1 , 2 As shown in Figure 3, the flame retardant liquid delivery mechanism 3 includes a first liquid storage container 31, an electromagnetic switch valve 32, and a first delivery pipe 33; the first liquid storage container 31 is disposed above the side wall 2; the input end of the electromagnetic switch valve 32 is connected to the first liquid storage container 31; the output end of the electromagnetic switch valve 32 is connected to one end of the first delivery pipe 33; the other end of the first delivery pipe 33 passes through the top wall 1 and the side wall 2, and is connected to the flame retardant inner cavity 201; and the electromagnetic switch valve 32 is electrically connected to the button 41.
[0033] Specifically, in some implementations, such as Figure 1 and 2 As shown, the side wall 2 includes an outer metal plate 21, a heat insulation plate 22, and an inner metal plate 23 stacked sequentially from the outside to the inside; the flame-retardant inner cavity 201 is disposed inside the inner metal plate 23; the button 41 is connected to the inner metal plate 23; the thermal expansion component 42 (corrugated pipe 422) abuts against the inner metal plate 23 (the mounting block 423 in the thermal expansion component 42 is fixedly connected to the inner metal plate 23). The heat insulation plate 22 is a polyurethane foam board; the inner metal plate 23 is made of alloy materials such as aluminum, steel, and stainless steel; the outer metal plate 21 is made of alloy materials such as aluminum, steel, and stainless steel.
[0034] Specifically, in some implementations, such as Figure 1 and 2As shown, a temperature sensing element 5 is provided on the outer surface of the side wall 2; a spraying mechanism 6 is provided on the outer top of the top wall 1; the spraying mechanism 6 is used to spray the top wall 1 and / or the side wall 2. That is, the spraying mechanism 6 will only be activated when the temperature sensing element 5 detects that the external temperature is too high (reaching a state of spontaneous combustion, etc.) to spray the top wall 1 and / or the side wall 2. The temperature sensing element 5 can be a KSD301 or HCET-A temperature control button; when the temperature reaches a certain value, the spraying mechanism 6 can be automatically controlled to spray the top wall 1 and / or the side wall 2.
[0035] Specifically, in some implementations, such as Figure 1 As shown, the spraying mechanism 6 includes a second liquid storage container 61, a support 62, and a spraying component 63; the support 62 is connected to the outer top of the top wall 1; the second liquid storage container 61 is disposed inside the support 62; the spraying component 63 is mounted on the support 62 and communicates with the interior of the second liquid storage container 61. Wherein, as... Figure 4 As shown, the spray component 63 includes a liquid pump 631, a second delivery pipe 632, and at least one nozzle 633. The input end of the liquid pump 631 is connected to the bracket 62 and communicates with the interior of the second liquid storage container 61. One end of the second delivery pipe 632 is connected to the output end of the liquid pump 631. The other end of the second delivery pipe 632 is provided with at least one branch pipe 634. Each branch pipe 634 is connected to the nozzle 633. Further, the temperature sensing component 5 is electrically connected to the liquid pump 631. Further still, the top outer surface of the top wall 1 is provided with a guide slope 11; the lowest point of the guide slope 11 connects to the horizontal plane where the top of the side wall 2 is located. That is, when the temperature reaches a preset value, the nozzle 633 sprays fire extinguishing liquid towards the top outer surface of the top wall 1, which flows through the top wall 1 to the outer surface of the side wall 2, thereby achieving external fire protection.

Therefore, this utility model is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this utility model are within the protection scope of this utility model.
