[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0026] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.
[0027] The present application is described below with reference to the accompanying drawings and specific embodiments:
[0028] Alarms are often installed at production sites to maintain fire safety. Manually operated alarms are usually installed at a lower height to facilitate on-site personnel. However, in working environments such as high-temperature ingot finishing areas, manually operated alarms are particularly close to high-temperature areas, which greatly increases the risk of manual alarms melting, false triggering, and loss of function, seriously threatening fire safety.
[0029] To this end, an embodiment of the present application provides a high temperature resistant fire alarm device, which aims to improve the structural and functional reliability of alarm facilities that require operation, such as manual alarms, in high temperature environments to a certain extent, while taking into account the convenience of operation.
[0030] See also Figure 1 In some embodiments, the high temperature resistant fire alarm device can be implemented by means of an openable and closable external heat insulation protection; specifically, the high temperature resistant fire alarm device may include: a heat insulation box 1 and an alarm 2 arranged therein.
[0031] Wherein, the alarm 2 may include a manual alarm, such as a manual alarm button, etc.
[0032] The heat insulation box 1 is a protective box body with fireproof and heat-insulating functions, and may include: a box frame 11 , a fireproof and heat-insulating board 12 , and a fireproof door 13 .
[0033] The box frame 11 is a frame in the form of a skeleton, with sufficient functional structures such as structural beams and columns, and can install and carry other components. Correspondingly, the fireproof insulation board 12 can be connected to the box frame 11 by filling, so as to form the box structure of the insulation box 1 based on the box frame 11, and the space enclosed inside can accommodate and protect the alarm 2. For the convenience of operation, an operation window 111 can be reserved on one side of the box structure of the insulation box 1, so that the on-site personnel can reach into the insulation box 1 and operate the manual alarm.
[0034] In order to ensure the fireproof and heat-insulating performance of the thermal insulation box 1, the fireproof door 13 can be slidably arranged on the box structure of the thermal insulation box 1, and the moving range of the fireproof door 13 covers the operating window 111, so that the operating window 111 can be opened and closed by moving the fireproof door 13; the fireproof door 13 closes the operating window 111 to form a complete enclosed space, which is heat-insulating and fire-proof, and protects the alarm 2; when the alarm 2 needs to be operated, the fireproof door 13 can be removed to expose the operating window 111.
[0035] In order to improve the thermal insulation and sealing performance of the movable structural mode of the fire door 13, a heat-resistant rubber strip 112 can be set at the edge of the operating window 111, and it can be abutted against the fire door 13 to form a contact seal, thereby ensuring the isolation stability inside and outside the box structure of the thermal insulation box 1.
[0036] In some embodiments, the fireproof insulation board 12 can be wrapped around the outside of the box frame 11 to wrap the entire box frame 11, thereby protecting the box frame 11 to a certain extent, limiting heat accumulation, ensuring the structural stability of the box frame 11, and preventing heat from entering the box structure of the insulation box 1 through the box frame 11.
[0037] Generally speaking, screw holes can be opened on one side of the fireproof and heat-insulating board 12 close to the box frame 11, and the board can be fixed to the box frame 11 by bolts.
[0038] Of course, it can also be fixed to the box frame 11 by other fasteners such as clips, hooks, tension springs, etc.; it can also be further filled with adhesive material between the fireproof insulation board 12 and the box frame 11 to enhance the fixing effect and seal the gap to limit the heat radiation into the box structure of the insulation box 1.
[0039] In some embodiments, in order to further enhance the thermal insulation capability, the thermal insulation box 1 may further include a thermal insulation inner panel 14, which is disposed in the box frame 11 and arranged opposite to the fireproof thermal insulation panel 12, thereby forming a double-layer thermal insulation structure to enhance the thermal insulation performance.
[0040] Generally speaking, the heat insulating inner panel 14 can be fixed to the inner side surface of the box frame 11 by fasteners.
[0041] In some embodiments, the box frame 11 can be connected to each other by angle steel to form a frame structure, such as a rectangular frame; screw holes can be opened on the angle steel pillars and beams, and the fireproof insulation board 12 and the insulation inner board 14 can be fixed to the box frame 11 with bolts.
[0042] Generally speaking, the pillars and crossbeams of the box frame 11 can be connected by welding, which simplifies the preparation operation and maintains reliable structural strength.
[0043] In some embodiments, the heat-insulating inner panel 14 can be configured as a panel with heat-insulating capability such as a vacuum insulation panel, or can be other panels with heat-insulating capability.
[0044] In some embodiments, in order to further enhance the thermal insulation performance, a heat reflective coating layer, such as a silver foil layer, is provided on a side of the thermal insulation inner panel 14 close to the fireproof thermal insulation panel 12 .
[0045] In some embodiments, a layer of heat insulating material may be filled between the heat insulating inner panel 14 and the fireproof heat insulating panel 12 to further reduce heat transfer.
[0046] In some embodiments, the thermal insulation material layer may be one of polyurethane rigid foam, polystyrene board, rock wool board and rubber powder polystyrene particle insulation slurry.
[0047] In some embodiments, the fireproof door 13 may include: a door body and a slide rail; the slide rail is arranged on the box frame 11, the door body is slidably arranged on the slide rail, and the heat-resistant adhesive strip 112 slides against the door body.
[0048] The slide rail is fixed on the outer surface of the box frame 11, and the heat-resistant rubber strip 112 is arranged on the edge of the box frame 11 to cooperate with the door body for sliding sealing.
[0049] In some embodiments, in order to improve the reliability of the fire door 12 , a door hook lock may be connected between the door body and the box frame 11 .
[0050] In some embodiments, in order to facilitate warning, an alarm mark may be sprayed on the fireproof insulation board 12 and / or the fireproof door 13.
[0051] In some embodiments, a mounting and fixing bracket that cooperates with the alarm 2 can be set in the thermal insulation box 1 to control the distance from the alarm 2 to the inner surface of the thermal insulation box 1 to be more than 3 cm, so as to effectively prevent heat conduction and play a role in heat insulation.
[0052] The embodiments of the present application have at least the following beneficial effects:
