Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting devices, and in particular to an intelligent fire fighting automatic detection device. Background Art

[0002] Fire refers to a disaster caused by uncontrolled combustion in time or space. Among various disasters, fire is one of the major disasters that most frequently and commonly threatens public safety and social development. Fire prevention is the core of fire prevention work. Smart firefighting is an advanced fire prevention solution that minimizes fire risks and impacts through earlier detection and faster processing.

[0003] Fire alarm is a common fire detection device. Its sensitivity is adjusted before leaving the factory. If the sensitivity needs to be adjusted, there is currently no better solution except returning the product to the factory for adjustment. In complex environments, excessive sensitivity can easily lead to problems such as false alarms. After long-term use of the fire alarm, dust easily accumulates on the surface of the smoke alarm, which may cause the alarm to malfunction. Cleaning the dust requires disassembling the alarm, which is troublesome. Utility Model Content

[0027] Example

[0028] A smart fire automatic detection device, comprising:

[0029] The main body 100, such as Figure 1 and Figure 2 As shown, it includes a mounting plate 101, a housing 102, a smoke alarm 103 and two groups of limiting columns 104. Both ends of the housing 102 are connected. The housing 102, the smoke alarm 103 and the two groups of limiting columns 104 are fixedly connected to the bottom of the mounting plate 101. The smoke alarm 103 and the two groups of limiting columns 104 are located inside the housing 102, and the bottom of the smoke alarm 103 passes through the housing 102.

[0030] Shielding mechanism 200, such as Figure 2 As shown, it includes a porous shielding cylinder 201, a connecting plate 202, a limiting cylinder 203, a threaded cylinder 204 and an adjusting component. The porous shielding cylinder 201 is sleeved outside the smoke alarm 103 and fits with the bottom cover of the shell 102. The connecting plates 202 are provided with three groups. The three groups of connecting plates 202 are fixedly connected to the top of the outer side of the porous shielding cylinder 201 and are evenly distributed around the porous shielding cylinder 201. The limiting cylinder 203 is provided with two groups and is slidably connected to the two groups of limiting columns 104 respectively. The threaded cylinder 204 and the two groups of limiting cylinders 203 are respectively fixedly connected to the side of the three groups of connecting plates 202 away from the porous shielding cylinder 201. The adjusting component is used to cooperate with the threaded cylinder 204 to adjust the upper and lower heights of the porous shielding cylinder 201;

[0031] The cleaning component 300 is used to clean the smoke alarm 103 and is rotatably connected to the bottom of the housing 102 .

[0032] Specifically, Figure 2 As shown, the adjustment assembly includes a screw 205 and a knob 206. The screw 205 is rotatably connected to the housing 102 and extends through the housing 102 to the mounting plate 101. The threaded barrel 204 is threadedly connected to the screw 205. The knob 206 is fixedly connected to the bottom end of the knob 206. When the screw 205 is rotated, the two groups of limit columns 104 and the two groups of limit barrels 203 cooperate to clamp the porous shielding barrel 201. The porous shielding barrel 201 cannot rotate, and the threaded barrel 204 cannot rotate. Therefore, the screw 205 rotates, and the threaded barrel 204 moves upward or downward along the screw 205.

[0033] The axes of the screw rod 205 and the knob 206 coincide with each other, which facilitates the rotation of the knob. Anti-skid grooves are provided on the outer side of the knob 206 to prevent the knob 206 from slipping when being rotated.

[0034] More specifically, Figure 2 and Figure 3 As shown, the cleaning assembly 300 includes a cover body 301 and multiple groups of brush plates 302. The cover body 301 is rotatably connected to the bottom of the shell 102 and has multiple groups of ventilation holes equidistantly opened on its side wall. The multiple groups of brush plates 302 are fixedly connected to the inner wall of the bottom of the brush plate 302 and are evenly distributed in a ring shape. The brush plate 302 is located between the porous shielding tube 201 and the smoke alarm 103 and has bristles on the inner side that fit the smoke alarm 103. When in use, the cover body 301 is rotated to allow the bristles of the brush plate 302 to brush away dust on the surface of the smoke alarm 103.

[0035] It should be noted that the bottom of the shell 102 has an annular protrusion with a flange on the outside, and the cover body 301 has a slot that fits with the annular protrusion at the cover opening. The cover body 301 is rotatably connected to the bottom of the shell 102 through the slot and the annular protrusion.

[0036] In addition, the axes of the mounting plate 101, the housing 102, the porous shielding tube 201 and the cover body 301 coincide with each other, and the porous shielding tube 201 can abut against the inner wall at the bottom of the cover body 301 to ensure the shielding effect.

[0037] Working principle: During the use of the utility model, according to actual use needs, the knob 206 can be rotated, and the knob 206 drives the screw 205 to rotate. When the screw 205 rotates, it drives the threaded tube 204 to move upward or downward along the screw 205, and then drives the porous shielding tube 201 to move upward or downward. When the porous shielding tube 201 moves downward, the smoke alarm 103 is shielded, which can reduce the sensitivity of the device and avoid false alarms. When the device is used for a long time and a lot of dust is accumulated on the surface of the smoke alarm 103, the cover body 301 is rotated, and the cover body 301 drives each group of porous shielding tubes 201 to rotate around the smoke alarm 103, brush off the dust on the surface of the smoke alarm 103, and avoid malfunction of the smoke alarm 103.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
