[0001] The utility model relates to the technical field of smoke exhaust ducts, in particular to a linear smoke exhaust duct fireproof board covering device. Background Art

[0002] After the smoke exhaust duct is installed, it is necessary to use fireproof panels to wrap the outer wall of the smoke exhaust duct so that the smoke exhaust duct can achieve the purpose of fire prevention and heat insulation to avoid fire caused by high temperature.

[0003] A linear smoke exhaust duct fireproof board covering device is disclosed, which relates to the technical field of smoke exhaust ducts, including a smoke exhaust duct and a fireproof board, wherein the fireproof board is installed in sections on the outside of the smoke exhaust duct, and adjacent fireproof boards are connected with reinforcing flat steels, and the lower end of the reinforcing flat steels is installed with sealing pads, and both sides of the reinforcing flat steels are installed with fixing bolts, and the four corners of the fireproof board are installed with right-angle guard steels, and the outer wall of the smoke exhaust duct is installed with a heat insulation pad. When the fireproof board is installed on the outside of the smoke exhaust duct, a gap will be left between the two, so as to avoid direct contact between the smoke exhaust duct and the fireproof board, and to avoid the fireproof board being subjected to high temperature and being transmitted to the smoke exhaust duct to cause damage to the smoke exhaust duct. The fireproof board is spliced ​​by connecting end plates and connecting side plates. Once one side of the fireproof board is damaged, only the damaged side needs to be disassembled, and there is no need to replace the entire protective board.

[0004] In the above-mentioned prior art, a heat insulating pad is installed between the smoke exhaust duct and the fireproof board so that the heat generated by the smoke exhaust duct cannot be transferred to the fireproof board, and at the same time, the heat from the fireproof board being subjected to high temperature is prevented from being transferred to the smoke exhaust duct and causing damage to the smoke exhaust duct. However, isolating the heat emitted by the smoke exhaust duct with the heat insulating pad will cause the heat to continue to accumulate in the smoke exhaust duct. When the temperature is too high, it will damage the smoke exhaust duct, seriously reducing the service life of the smoke exhaust duct. Utility Model Content

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] like Figure 1-5 As shown, a linear smoke exhaust duct fireproof board covering device includes:

[0027] Fireproof panels 1 are arranged in a linear array and spliced ​​with each other, and water storage chambers 2 are provided in the fireproof panels 1. The water storage chambers 2 in two adjacent fireproof panels 1 are connected with each other.

[0028] A U-shaped copper sheet 4 is linearly arrayed in the fireproof board 1, and the top of the U-shaped copper sheet 4 extends into the water storage chamber 2;

[0029] A ceramic block 5 is slidably arranged at the bottom end of the fireproof board 1 and is driven to abut against the bottom end of the U-shaped copper sheet 4.

[0030] Specifically, after the fireproof board 1 is installed, the ceramic block 5 installed by sliding at the bottom of the fireproof board 1 abuts against the outer wall of the smoke exhaust duct, so that the ceramic block 5 absorbs the heat of the smoke exhaust duct to avoid heat accumulation in the smoke exhaust duct, and at the same time can also avoid the temperature from being transferred to the room. The ceramic block 5 is driven by pressure during the installation process and abuts against the bottom of the U-shaped copper sheet 4, so that the ceramic block 5 continuously transfers the absorbed temperature to the U-shaped copper sheet 4, and the U-shaped copper sheet 4 is continuously cooled by the coolant poured into the water storage chamber 2, so that the heat absorbed by the ceramic block 5 can be quickly absorbed by the coolant through the U-shaped copper sheet 4, so that the fireproof board 1 can dissipate heat to the smoke exhaust pipe while preventing fire, thereby improving the service life of the smoke exhaust pipe. When multiple fireproof boards 1 wrap the smoke exhaust pipe, multiple adjacent water storage chambers 2 are interconnected, so that the heat dissipation effect of the fireproof board 1 is higher.

[0031] In the above embodiment, when the fireproof board 1 is installed on the smoke exhaust duct and wrapped, the ceramic block 5 installed at the bottom of the fireproof board 1 abuts against the outer wall of the smoke exhaust duct to absorb the heat generated by the smoke exhaust duct and avoid damage caused by the heat accumulation of the smoke exhaust duct. During installation, the ceramic block 5 is driven to abut against the U-shaped copper sheet 4, so that the heat absorbed by the ceramic block 5 can be transferred to the U-shaped copper sheet 4, and extend into the water storage chamber 2 through one end of the U-shaped copper sheet 4, so that the coolant in the water storage chamber 2 cools the U-shaped copper sheet 4, so that the U-shaped copper sheet 4 can continue to cool the ceramic block 5. After the fireproof board 1 is wrapped, adjacent water storage chambers 2 are interconnected, so that the coolants in multiple fireproof boards 1 can circulate with each other, which can not only enable the fireproof board 1 to dissipate the heat generated by the smoke exhaust duct, but also improve the fireproof effect of the fireproof board 1.

[0032] As an embodiment further provided by the present invention, a cavity 6 is provided at the bottom end of the fireproof board 1, and a ceramic block 5 is movably connected in the cavity 6.

[0033] Specifically, by installing the ceramic block 5 in the cavity 6, the heat absorbed by the ceramic block 5 can be isolated by the cavity 6, thereby improving the heat insulation effect of the fireproof board 1 and preventing the temperature from being directly transferred to the coolant over a large area, thereby affecting the cooling effect of the coolant.

[0034] As another embodiment further provided by the present invention, the bottom end of the U-shaped copper sheet 4 extends into the cavity 6 .

[0035] Specifically, the U-shaped copper sheet 4 extends into the cavity 6 , so that the ceramic block 5 is squeezed and abuts against the U-shaped copper sheet 4 during the process of sliding along the cavity 6 , and transfers the temperature to the U-shaped copper sheet 4 .

[0036] As another embodiment further provided by the present invention, a plug hole 3 is provided on the side wall of the fireproof board 1 , the plug hole 3 is connected to the water storage chamber 2 , and a sealing member 8 is symmetrically arranged in the plug hole 3 .

[0037] Furthermore, a conduit 7 is fixedly mounted on the side wall of the fireproof board 1 , one end of the conduit 7 is plugged into the insertion hole 3 , and one end of the conduit 7 abuts against the sealing member 8 .

[0038] Specifically, by inserting the conduit 7 into the socket 3, the conduit 7 pushes the seal 8 to open, so that the two adjacent water storage chambers 2 can be connected to each other, and the two adjacent fireproof panels 1 can be spliced ​​together. The conduit 7 can be bent so that the connection between the multiple fireproof panels 1 can be bent and the smoke exhaust duct can be wrapped.

[0039] As another embodiment further provided by the present invention, a spiral groove 11 in a circumferential array is provided at the side wall of the conduit 7 , and a limiting groove 13 in an array along the rotation path of the spiral groove 11 is provided in the conduit 7 .

[0040] Furthermore, a winding block 10 is fixedly installed at one end of the socket 3, one end of the winding block 10 is inserted into the spiral groove 11, and a limiting buckle 12 in a linear array is provided at the bottom end of the winding block 10, and the side wall of the limiting buckle 12 is inserted into the limiting groove 13.

[0041] Specifically, during the process of inserting the conduit 7 into the socket 3, the winding block 10 winds the conduit 7 along the spiral groove 11 opened on the conduit 7. The more the conduit 7 moves into the socket 3, the tighter the winding block 10 winds, so that the conduit 7 can be fixed in the socket 3, thereby fixing the connection between the two adjacent fireproof panels 1, and the limiting buckle 12 installed on the winding block 10 is inserted into the limiting groove 13, so that the winding block 10 is fixed more firmly.

[0042] Working principle: When the fireproof board 1 is installed on the smoke exhaust duct and wrapped, the ceramic block 5 installed on the fireproof board 1 abuts against the outer wall of the smoke exhaust duct. In the process of the ceramic block 5 abutting against the smoke exhaust duct, it is squeezed and slides up along the cavity 6 and abuts against the U-shaped copper sheet 4, so that the ceramic block 5 absorbs the heat of the smoke exhaust duct and continuously transfers it to the U-shaped copper sheet 4, and extends into the water storage chamber 2 through one end of the U-shaped copper sheet 4, so that the coolant in the water storage chamber 2 cools the U-shaped copper sheet 4, so that the U-shaped copper sheet 4 can continuously cool the ceramic block 5, and the conduit 7 installed on the fireproof board 1 is inserted into the socket 3 opened on another adjacent fireproof board 1, so that the adjacent water storage chambers 2 can be connected to each other, and the two adjacent fireproof boards 1 can be spliced ​​with each other for fire protection, and the conduit 7 is fixed along the spiral groove 11 by the winding block 10 installed in the socket 3, so that the conduit 7 can be fixed, thereby improving the connection strength between the two adjacent fireproof boards 1.

[0043] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
