[0025] The following will further describe the present application in detail with reference to the attached Figure 1 - Figure 4 to further illustrate the present application,

[0026] The embodiment of the present application discloses a chemical instrument and electrical cabinet with a fire alarm function. Refer toFigure 1 - Figure 4 , a chemical instrument electrical cabinet with a fire alarm function, including a cabinet shell 1, a cabinet door 4 is hinged to one side of the cabinet shell 1, and a control panel 5 is fixedly installed at the top of one side of the cabinet door 4; a fire alarm component 2 is fixedly installed at the top inside the cabinet shell 1, and the fire alarm component 2 includes a partition 201, a ventilation pipe 202, a solenoid valve 203, a gas storage tank 204 and a nozzle 206;

[0027] A positioning and replacement component 3 is fixedly installed in the middle of the outside of the cabinet shell 1, and the positioning and replacement component 3 includes a protective cover 301, a sliding rod 302, a filter screen 303 and a rubber pad 304.

[0028] Refer to Figure 1 , Figure 2 and Figure 3 , the fire alarm component 2 further includes a support frame 205, a smoke sensor 207 and an alarm 208;

[0029] The top inside the cabinet shell 1 is fixedly connected to the outside of the partition 201, the middle inside the partition 201 is fixedly connected to the outside of the ventilation pipe 202, the middle inside the ventilation pipe 202 is fixedly connected to the outside of the solenoid valve 203, the input end of the solenoid valve 203 is electrically connected to the output end of an external power supply, the top of the ventilation pipe 202 is snap-connected to the bottom end of the gas storage tank 204, and a sealing door is hinged at a position corresponding to one side of the gas storage tank 204 at the top of one side of the cabinet shell 1, which can protect the top inside the cabinet shell 1. The bottom ends of two support frames 205 are respectively fixedly connected to both sides of the top of the partition 201, and the top of the support frame 205 contacts the bottom of the gas storage tank 204, ensuring the stability of the gas storage tank 204 when placed. The tops of several nozzles 206 are fixedly connected to the bottom end of the ventilation pipe 202 at equal distances. The nozzles 206 and the smoke sensor 207 are both located inside the cabinet shell 1, which can extinguish fires inside the cabinet shell 1. The bottom corner position of the partition 201 is fixedly connected to the outside of the smoke sensor 207, and the top corner position of the cabinet shell 1 is fixedly connected to the bottom end of the alarm 208.

[0030] Refer to Figure 1 and Figure 4 , the positioning and replacement component 3 further includes a clamping block 305, a support rod 306 and a magnetic strip 307;

[0031] On one side of the two protective covers 301, the top parts are respectively hinged to the middle parts on both sides of the cabinet shell 1. On the outer sides of the two sliding rods 302, they are respectively slidably connected to the two side edges of the inner side of the protective cover 301. On one side of the two sliding rods 302, they are respectively fixedly connected to both sides of the filter screen 303. The inner side of the sliding rod 302 is fixedly connected to the outer side of the rubber pad 304. On the outer sides of the two clamping blocks 305, they are respectively clamped to the two side edges of the bottom end of the protective cover 301. On one side of the two clamping blocks 305, they are respectively fixedly connected to the two side edges of one side of the support rod 306. The top end of the support rod 306 contacts the bottom end of the filter screen 303, which can support the moved filter screen 303. The inner side of the support rod 306 is fixedly connected to the outer side of the magnet strip 307. One side of the magnet strip 307 is magnetically adsorbed to the outer side of the cabinet shell 1, which can fix the position of the support rod 306 after rotation;

[0032] Working principle: The staff moves the gas storage tank 204. Since the gas storage tank 204 is slidably connected to the inner side of the cabinet shell 1, the moving direction of the gas storage tank 204 can be limited. When the gas storage tank 204 moves to a suitable position, the gas storage tank 204 is clamped to the ventilation pipe 202, and then the installation of the gas storage tank 204 is completed. At this time, the support frame 205 fixedly installed at the top end of the partition plate 201 contacts the bottom end of the gas storage tank 204, which can support the installed gas storage tank 204. During the use of the cabinet shell 1, through the smoke sensor 207, the fire inside the cabinet shell 1 can be detected. When a fire occurs inside the cabinet shell 1, the alarm 208 fixedly installed at the top end of the cabinet shell 1 is activated, which can warn the personnel. At the same time, the solenoid valve 203 is activated, which can make the carbon dioxide gas stored inside the gas storage tank 204 flow along the inner side of the ventilation pipe 202 and spray out from the inner side of the nozzle 206 fixedly connected to the bottom end of the ventilation pipe 202, and then the inside of the cabinet shell 1 can be extinguished.

[0033] The staff member pulls the protective cover 301. Through the hinge connection between the protective cover 301 and the cabinet shell 1, the protective cover 301 can be rotated. When the protective cover 301 rotates to a suitable position, the staff member moves the filter screen 303. During the movement of the filter screen 303, since the outer side of the filter screen 303 is fixedly connected to the sliding rod 302 and the sliding rod 302 is slidably connected to the inner side of the protective cover 301, the moving direction of the sliding rod 302 can be limited. When the sliding rod 302 moves to a suitable position, the rubber pad 304 fixedly installed on the inner side of the sliding rod 302 presses against the inner side of the protective cover 301, which can limit the position of the filter screen 303 after movement. At this time, the staff member moves the support rod 306. During the movement of the support rod 306, the block 305 fixedly installed on one side of the support rod 306 is clamped to the inner side of the protective cover 301, which can fix the position of the support rod 306 after movement. By the contact between the top end of the support rod 306 and the bottom end of the filter screen 303, the position of the filter screen 303 after movement can be fixed, thus completing the installation of the filter screen 303. Finally, the staff member rotates the protective cover 301, which can move the position of the support rod 306 fixedly connected to the bottom of the protective cover 301. When the support rod 306 moves to a suitable position, the magnetic strip 307 fixedly installed on the inner side of the support rod 306 is magnetically adsorbed to the cabinet shell 1, which can fix the position of the rotated protective cover 301. Through the protective cover 301, the filter screen 303 can be protected. Through the filter screen 303, the gas entering the inner side of the cabinet shell 1 can be filtered.

[0034] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only used to illustrate the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
