[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-4 A noise reduction and heat insulation board includes a push-button fire alarm 11, an inner panel 1, a heat insulation asbestos board 2, a frame 3, a sound-absorbing sponge layer 13, and an outer panel 14. It should be noted that the inner panel 1, the heat insulation asbestos board 2, the frame 3, the sound-absorbing sponge layer 13, and the outer panel 14 are stacked layer by layer, and the inner panel 1 is laid flat on the mounting surface. For example, the inner panel 1 is laid flat on the inner wall of the ship's power room. The frame 3 includes a number of equally spaced recesses 301. The heat insulation asbestos board 2 is provided with protrusions that match the recesses 301 one by one. The sound-absorbing sponge layer 13 is provided with grooves that correspond to the recesses 301 one by one.

[0028] Furthermore, a thermal expansion protrusion 302 is provided at the end of the frame 3 away from the inner panel 1. The thermal expansion protrusion 302 is arc-shaped and is installed at the end of the heat insulation asbestos board 2 away from the inner panel 1. When a fire is about to occur, the temperature of the entire heat insulation board rises, and the frame 3 expands after being heated. At the position of the thermal expansion protrusion 302, it will expand towards the side of the sound-absorbing sponge layer 13 with a smaller reverse force. A needle 5 is installed at the thermal expansion protrusion 302. The needle 5 is installed at the apex of the arc of the thermal expansion protrusion 302.

[0029] Furthermore, a warning box 6 is provided at the end of the frame 3 away from the inner plate 1. The push-type fire alarm 11 is installed in the warning box 6. The warning box 6 contains a filling bag 7 that expands due to the filling material. One end of the filling bag 7 is pressed against the pressing plate 10. When the frame 3 is heated, the thermal expansion protrusion 302 inside it expands outward under the action of force. During the expansion process, the push needle 5 moves to puncture the filling bag 7. The filling bag 7 that is not punctured will squeeze the pressing plate 10 under the pressure of the liquid inside, so that there is a certain gap between it and the push-type fire alarm 11. After it is punctured, the pressing plate 10 moves towards the push-type fire alarm 11 under the action of the push assembly 12. Pressing the button inside it will turn on the push-type fire alarm 11 and play a fire warning role.

[0030] Specifically, two square blocks are installed on the outer ring of the pressing plate 10. The square blocks are slidably connected to the inner wall of the guide groove in the warning box 6. A pressing block 1001 is provided on the pressing plate 10 at the position of the button in the press-type fire alarm 11. A thrust assembly 12 is installed between the pressing plate 10 and the press-type fire alarm 11. The thrust assembly 12 is used to push the pressing plate 10 to move towards the press-type fire alarm 11 after the needle 5 punctures the filling bag 7, so as to press the button of the press-type fire alarm 11 and start the press-type fire alarm 11.

[0031] It should be noted that a guide 4 is provided between the warning box 6 and the thermal expansion protrusion 302. A gap is provided between the guide 4 and the thermal expansion protrusion 302 to allow the thermal expansion protrusion 302 to expand and move outward. The needle 5 is inserted into the guide groove in the guide 4.

[0032] Specifically, there is a cavity between the filling bag 7 and the inner wall of the warning box 6. One end of the cavity is connected to the through hole on the warning box 6, and the other end is connected to the liquid discharge pipe 601. Multiple liquid discharge pipes 601 are arranged in a circumferential array on the inner wall of the warning box 6. After the filling bag 7 is punctured by the needle 5, the liquid that flows out enters the cavity through the liquid discharge pipe 601 and eventually flows out from the through hole. The filling bag 7 is stuck into the hoop plate 8, and the cavity is formed by the hoop plate 8 and the inner wall of the warning box 6.

[0033] The thrust assembly 12 can adopt the following two schemes. In the first scheme, the thrust assembly 12 includes a magnet 1201 and an adsorption block 1202. The adsorption block 1202 is aligned with the magnet 1201, and the magnet 1201 and the adsorption block 1202 are respectively installed on the circular plate where the pressing plate 10 and the pressing fire alarm 11 are located.

[0034] In the second embodiment, the thrust assembly 12 includes a spring 1203, with both ends of the spring 1203 mounted on the circular plate where the pressing plate 10 and the pressing fire alarm 11 are located.

[0035] Working principle:

[0036] The entire heat insulation board is divided into several parts, including inner board 1, heat insulation asbestos board 2, frame 3, sound-absorbing sponge layer 13, and outer board 14. The heat insulation asbestos board 2 and the sound-absorbing sponge layer 13 are located on both sides of the frame 3, playing the roles of heat insulation and sound absorption. The setting of heat insulation asbestos board 2 and sound-absorbing sponge layer 13 increases the heat insulation performance and noise reduction performance of the heat insulation board.

[0037] Inside the heat insulation board are components such as a warning box 6 and a push-button fire alarm 11. When the frame 3 expands due to heat, it will squeeze the needle 5. Under the action of the squeezing force, the needle 5 moves towards the filling bag 7 and eventually punctures the filling bag 7. The water in the filling bag 7 is discharged from the liquid discharge pipe 601, the cavity, and the through hole. The water in the filling bag 7, which was originally squeezed by the pressing plate 10 and was separated from the push-button fire alarm 11, flows out, reducing the squeezing force on the pressing plate 10. At this time, the pressing plate 10 moves towards the push-button fire alarm 11 under the action of the thrust assembly 12, and finally presses the button of the push-button fire alarm 11 to start the alarm.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
