[0032] like Figure 1-Figure 5 As shown, a fire protection device in an embodiment of the utility model includes a fire extinguisher cabinet body 1 and a positioning alarm mechanism 2.

[0033] A storage cavity is provided on the upper part of the fire extinguisher cabinet body 1 , a first partition plate 101 is installed in the storage cavity, and an installation cavity and a filling cavity are formed between the inner wall of the fire extinguisher cabinet body 1 and the first partition plate 101 .

[0034] In addition, a through hole is drilled in the side wall of the fire extinguisher cabinet body 1, and the installation cavity is connected to the outside through the through hole. When a fire occurs in the outside, the heat generated by the fire combustion will enter the installation cavity through the through hole to activate the trigger mechanism so that the alarm 202 can alarm, which is convenient for the user to find the fire extinguisher cabinet body 1 in time.

[0035] Specifically, a filter screen 102 is installed in the through hole to block external dust so that dust is not easy to enter the installation cavity.

[0036] like Figure 1-Figure 5 As shown, the positioning alarm mechanism 2 is installed in the installation cavity. The positioning alarm mechanism 2 is used to sound an alarm so that the user can find the position of the fire extinguisher cabinet body 1 in an unfamiliar environment in time, and then use the fire-fighting tools in the fire extinguisher cabinet body 1 to extinguish the fire in time, making it difficult for the fire to spread further, thereby ensuring the property and personal safety of the user.

[0037] Among them, the positioning alarm mechanism 2 includes a power supply 201 and an alarm 202. The power supply 201 is electrically connected to the alarm 202. The power supply 201 is used to power the alarm 202 and the submersible pump 301. When the trigger mechanism is activated, the power supply 201, the alarm 202 and the trigger mechanism can form a pathway, so that the alarm 202 can sound an alarm to remind the user so that the user can quickly find the fire extinguisher cabinet body 1.

[0038] Preferably, the power source 201 and the alarm 202 are both commercially available products and can be used directly.

[0039] In addition, the installation cavity is provided with a heat insulation board, and the power supply 201 and the alarm 202 are respectively arranged on both sides of the heat insulation board to isolate the heat in the installation cavity, so that the power supply 201 is not easily affected by the heat, thereby ensuring the safety of the fire extinguisher cabinet body 1.

[0040] Preferably, the insulation board is one of a rock wool insulation board, a polyurethane foam insulation board or an ultra-fine glass wool insulation board.

[0041] like Figure 1-Figure 5 As shown, a trigger mechanism is provided in the installation cavity, and the trigger mechanism is installed on the side wall of the first partition 101. When the heat generated by the fire enters the installation cavity, the trigger mechanism will be activated due to the influence of the temperature, and then the alarm 202 can sound an alarm.

[0042] The trigger mechanism includes a mounting plate 203 , on which a pair of wiring terminals 204 are fixedly connected. The pair of wiring terminals 204 are electrically connected to the power source 201 and the alarm 202 , respectively.

[0043] In addition, a pair of bimetallic strips 205 are installed on the mounting plate 203, and contacts 206 are installed on the sides of the bimetallic strips 205 that are close to each other. When the heat generated by the fire enters the mounting cavity, the bimetallic strips 205 will bend due to the heat, so that the contacts 206 connected to the bimetallic strips 205 can contact each other. At this time, the power supply 201, the alarm 202 and the mounting plate 203 form a passage, so that the alarm 202 can send a positioning alarm to remind the user of the location of the fire extinguisher cabinet body 1.

[0044] Preferably, the bimetallic strip 205 is made of copper and iron. When the temperature exceeds 60° C., since the copper strip expands more than the iron strip, the bimetallic strip 205 will bend toward the iron strip, causing a pair of contacts 206 to come into contact.

[0045] like Figure 1-Figure 5As shown, the filling chamber is filled with cooling liquid 3. When the alarm 202 sounds an alarm, the submersible pump 301 will also run. The cooling liquid 3 is poured on the cover door of the fire extinguisher cabinet body 1 under the action of the submersible pump 301 to reduce the temperature of the cover door handle, making it convenient for the user to open the cover door of the fire extinguisher cabinet body 1 so as to take out the fire-fighting tools in the fire extinguisher cabinet body 1.

[0046] Preferably, the cooling liquid 3 is water.

[0047] A submersible pump 301 is installed in the cooling liquid 3 , and the submersible pump 301 is electrically connected to the power supply 201 . The submersible pump 301 is used to extract the cooling liquid 3 and deliver it to the straight pipe 303 .

[0048] In addition, a protective cover 302 is fixedly connected to the side wall of the fire extinguisher cabinet body 1 , and the protective cover 302 is used to protect the straight pipe 303 .

[0049] Specifically, a straight pipe 303 is installed in the protective cover 302, and the straight pipe 303 is connected to the output end of the submersible pump 301. The cooling liquid 3 extracted by the submersible pump 301 will be transported to the straight pipe 303, and then sprayed out through the spray head 304 to reduce the temperature of the door handle of the fire extinguisher cabinet body 1, so that the user can open the door and take out the fire-fighting tools in the fire extinguisher cabinet body 1.

[0050] In addition, a number of evenly distributed spray heads 304 are installed on the straight pipe 303, and a spray hole is provided at the bottom of the protective cover 302, and the spray head 304 corresponds to the spray hole. The cooling liquid 3 in the straight pipe 303 is sprayed out through the spray head 304, and then sprayed on the door handle of the fire extinguisher cabinet body 1 through the spray hole, thereby reducing the temperature of the door handle, making it less likely for the user to be scalded when opening it, so that the user can safely take out the fire-fighting tools in the fire extinguisher cabinet body 1.

[0051] Furthermore, an observation panel and a liquid replenishing pipe are provided on the side wall of the fire fighting cabinet body 1 for replenishing the cooling liquid 3 in time.

[0052] During specific use, when a fire occurs outside, the heat generated by the fire will enter the installation cavity through the through hole, thereby causing the temperature of the bimetallic strip 205 to rise.

[0053] When the temperature of the bimetallic strips 205 exceeds a certain value, the pair of bimetallic strips 205 will bend toward each other, thereby allowing the pair of contacts 206 to contact each other. At this time, the power supply 201, the alarm 202 and the trigger mechanism will form a closed loop, and the alarm 202 will sound an alarm under the action of the power supply 201 to remind the user of the location of the fire extinguisher cabinet body 1, so that the user can find the fire extinguisher cabinet body 1 in time in an unfamiliar environment and use the fire-fighting tools in the fire extinguisher cabinet body 1 to extinguish the fire.

[0054] When the trigger mechanism is activated, the submersible pump 301 will also run, the submersible pump 301 extracts the cooling liquid 3 and delivers it to the straight pipe 303, the cooling liquid 3 in the straight pipe 303 is sprayed out through the sprinkler head 304, and poured on the door handle of the fire extinguisher cabinet body 1 through the sprinkler head 304, so as to reduce the temperature of the door handle of the fire extinguisher cabinet body 1, so that the user is not easily scalded when opening the door of the fire extinguisher cabinet body 1, and the user can safely use the fire-fighting tools in the fire extinguisher cabinet body 1 to extinguish the fire.
