Detailed Implementation

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0032] See Figures 1-5 As shown, a flame-retardant heat-insulating color steel plate includes an upper substrate 1, a lower substrate 2, and a core layer 3. The core layer 3 is disposed between the upper substrate 1 and the lower substrate 2 to form the color steel plate body. A side plate 4 is respectively disposed on the left and right sides of the color steel plate body. A spraying mechanism 5 is respectively disposed on a pair of side plates 4, and a water supply hole 41 and a spray nozzle 42 communicating with the spraying mechanism 5 are opened. The spraying mechanisms 5 are connected to each other through a pipe 6.

[0033] Furthermore, in this embodiment, the core layer 3 is bonded between the upper substrate 1 and the lower substrate 2, and the core layer 3 is made of rock wool.

[0034] Further, see Figures 4-5As shown, in this embodiment, each spray mechanism 5 includes six sets of nozzles 51, a water collection tank 52, and telescopic components 54 corresponding to each nozzle 51. During connection, the nozzles 51 are installed at the front end of the telescopic components 54, allowing the nozzles 51 to extend and retract. The rear end of the telescopic components 54 is connected to the water collection tank 52 via a water distribution pipe 53. During installation, three sets of nozzles 51 face the front end of the side plate 4, and the other three sets of nozzles 51 face the... On the rear end face of the side plate 4, each set of nozzles 51 is directly opposite to a set of spray nozzles 42, that is, each set of side plates 4 has six sets of spray nozzles 42. During spraying, the nozzles 51 can extend out of the side plate 4 through the spray nozzles 42 directly opposite them; and the water collection tank 52 is fixed on the side plate 4 and communicates with the water supply hole 41 opened on the side plate 4. It should be noted that the number of sets of nozzles 51 is only one embodiment and is not intended to limit the scope of this application.

[0035] Further, see Figures 6-7 As shown, in this embodiment, the telescopic component 54 includes a housing 541, a connecting rod 542 that can slide inside the housing 541, and a plug 543 connected to the rear end of the housing 541. When connected, the water distribution pipe 5 is connected to the rear end of the plug 543, and the nozzle 51 is located at the front end of the connecting rod 542. When spraying, the nozzle 51 slides forward inside the housing 541 with the connecting rod 542, thereby driving the nozzle 51 to extend out from the side plate 4 to realize the spraying operation.

[0036] In this embodiment, see Figures 8-9 As shown, the housing 541 is composed of an upper housing 5411 and a lower housing 5412. The upper housing 5411 has a stepped hole penetrating both the upper and lower end faces. This stepped hole includes a first stepped hole segment 54111, a second stepped hole segment 54112, and a third stepped hole segment 54113 with progressively increasing diameters. The opening of the first stepped hole segment 54111 is beveled. The upper end of the lower housing 5412 passes through the third stepped hole segment 54113 and is threadedly connected. The lower housing 5412 also has a stepped hole penetrating both the upper and lower end faces. This stepped hole includes a first hole segment 54121 and a second hole segment 54122 with gradually decreasing diameters. The diameter of the second hole segment 54122 is smaller than that of the second stepped hole segment 54112, but larger than that of the first stepped hole segment 54111.

[0037] And continue to see Figures 8-9As shown, the connecting rod 542 is a stepped rod, which includes a first stepped portion 5421, a second stepped portion 5422, and a third stepped portion 5423 with gradually decreasing outer diameters. The outer diameter of the first stepped portion 5421 is slightly smaller than the diameter of the second hole segment 54122, the outer diameter of the second stepped portion 5422 is larger than the outer diameter of the first stepped hole segment 54111, but the outer diameter of the third stepped portion 5423 is slightly smaller than the outer diameter of the first stepped hole segment 54111. A blind hole 54231 is formed on the end face of the third stepped portion 5423, the depth of the blind hole 54231 extends to the second stepped portion 5422, and an elongated hole 54221 communicating with the blind hole 54231 is formed on the outer surface of the second stepped portion 5422.

[0038] And continue to see Figures 8-9 As shown, the plug 543 has a through hole 5431 extending through the upper and lower end faces; and the outer surface of the plug 543 is stepped, including a first stepped section 5432, a second stepped section 5433 and a third stepped section 5434; when connected, the third stepped section 5434 passes through the hole section 54121 and is threaded, and the water distribution pipe 5 is connected to the first stepped section 5432.

[0039] Further, see Figure 1 As shown, in this embodiment, the spray nozzle 42 is provided with a sealing cover 7; in the non-spraying state, by setting the sealing cover 7, the aesthetics are improved, and dust and other particles can be effectively prevented from entering through the spray nozzle 42.

[0040] The working principle of this utility model is as follows:

[0041] Before use, connect the water supply hole 41 to the external water supply mechanism. During use, the external water supply mechanism supplies water to the water collection tank 52 through the water supply hole 41 and enters the telescopic assembly 54 through the water distribution pipe 53. At this time, the rear end of the connecting rod 542 receives water pressure and moves forward in the housing 541, thereby pushing the nozzle 51 out of the side plate 4 and pushing off the sealing cover 7 during the extension process. As the connecting rod 542 gradually moves forward of the housing 541, when the first step 5421 is completely moved into the second step hole section 54112, since the outer diameter of the first step 5421 is smaller than the hole diameter of the second step hole section 54112, water enters the second step hole section 54112 in front of the first step 5421 through the gap between the two, and flows into the blind hole 54231 through the elongated hole 54221, and then sprays onto the surface of the color steel plate through the nozzle 51 to achieve flame retardancy.

[0042] When multiple sets of color steel plates are used together, see [reference needed]. Figures 10-11As shown (C in the figure represents the color steel plate; D in the figure represents the docking plug), the water supply holes 41 of two adjacent sets of color steel plates are connected together by the docking plug, while the two outermost water supply holes 41 are connected to the external water supply mechanism.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
