[0028] Embodiment:
[0029] Please refer to Figures 1-4, a flame-retardant protection structure of a PPS board in this embodiment, includes a first fireproof board 1. A second fireproof board 2 is arranged at the right end of the first fireproof board 1. A first cavity 5 is opened at the right end of the first fireproof board 1. A second cavity 6 is opened at the left end of the second fireproof board 2. A groove 9 is opened at the right end of the first fireproof board 1. A protruding board 10 is fixedly connected to the left end of the second fireproof board 2. Water inlet holes 3 are opened at the tops of both the first fireproof board 1 and the second fireproof board 2. A sealing plug 4 is inserted into the inner wall of the water inlet hole 3. By inserting the protruding board 10 into the inside of the groove 9, the first fireproof board 1 and the second fireproof board 2 are initially positioned, facilitating subsequent connection and fixation of the first fireproof board 1 and the second fireproof board 2. The sides of the first fireproof board 1 and the second fireproof board 2 are connected and fixed by a side plate 12. Then, by pulling out the sealing plug 4, water is added into the inside of the first cavity 5 and the second cavity 6 through the water inlet holes 3, and then the sealing plug 4 is inserted into the water inlet hole 3 again. When a fire breaks out, the water inside the first fireproof board 1 and the second fireproof board 2 delays the temperature rise of the first fireproof board 1 and the second fireproof board 2, improving the fireproof effect of the first fireproof board 1 and the second fireproof board 2. And when the first fireproof board 1 or the second fireproof board 2 is burned through, the water will flow out accordingly, reducing the spread of the fire.
[0030] The size of the protruding board 10 is adapted to the size of the groove 9, and the surface of the protruding board 10 is inserted into the inner wall of the groove 9.
[0031] The inner wall of the first cavity 5 is fixedly connected with first reinforcing ribs 7. The number of the first reinforcing ribs 7 is set to four, and the four first reinforcing ribs 7 are symmetrically distributed with the first fireproof board 1 as the center. The load-bearing capacity of the first fireproof board 1 and the second fireproof board 2 is improved through the first reinforcing ribs 7 and the second reinforcing ribs 8, enhancing the stability.
[0032] The inner wall of the second cavity 6 is fixedly connected with second reinforcing ribs 8, and the number of the second cavities 6 corresponds to that of the first reinforcing ribs 7.
[0033] Front plates 11 are respectively fixedly connected to both ends of the first fireproof board 1 and the second fireproof board 2. A side plate 12 is arranged at one end of the first fireproof board 1.
[0034] The rear end of the side plate 12 is fixedly connected to the surfaces of the first fireproof board 1 and the second fireproof board 2, and the number of the side plates 12 is set to two.
[0035] Both the front plates 11 and the side plates 12 are made of polyurethane materials. The surfaces of the first fireproof board 1 and the second fireproof board 2 are protected through the front plates 11 and the side plates 12, improving the wear-resistant effect of the first fireproof board 1 and the second fireproof board 2.
[0036] In the embodiment of the present application, the implementation principle of a flame-retardant protection structure for a PPS board is as follows: the surfaces of the first fireproof board 1 and the second fireproof board 2 are protected by the front board 11 and the side board 12 to improve the wear resistance of the first fireproof board 1 and the second fireproof board 2. The protruding board 10 is inserted into the groove 9 to preliminarily position the first fireproof board 1 and the second fireproof board 2, facilitating subsequent connection and fixation of the first fireproof board 1 and the second fireproof board 2. The side board 12 is used to connect and fix the sides of the first fireproof board 1 and the second fireproof board 2. Then, by removing the sealing plug 4, water is added into the first cavity 5 and the second cavity 6 through the water inlet hole 3, and then the sealing plug 4 is inserted into the water inlet hole 3. When a fire breaks out, the water inside the first fireproof board 1 and the second fireproof board 2 delays the temperature rise of the first fireproof board 1 and the second fireproof board 2, improving the fireproof effect of the first fireproof board 1 and the second fireproof board 2. Moreover, when the first fireproof board 1 or the second fireproof board 2 is burned through, the water will flow out accordingly, reducing the spread of the fire, and improving the flame-retardant performance of the first fireproof board 1 and the second fireproof board 2, enhancing safety. The first reinforcing rib 7 and the second reinforcing rib 8 improve the bearing capacity of the first fireproof board 1 and the second fireproof board 2, enhancing stability.
