Description

Technical Field

[0001] This utility model relates to the field of electrical fire monitoring and alarm technology, specifically to an electrical fire monitoring and alarm device. Background Technology

[0002] Existing electrical fire monitoring and alarm devices can collect smoke and then trigger a smoke alarm. For example, utility model patent CN222213490U discloses an electrical fire monitoring and alarm device, which relates to the field of fire monitoring technology. The device includes an electrical fire monitoring and alarm mechanism. A drive mechanism is fixedly connected to the top of the mechanism, and a slide rail mechanism engages with the surface of the drive mechanism. A camera mechanism is fixedly connected to the bottom of the mechanism. The slide rail mechanism includes a sliding rail, and meshing teeth are fixedly connected to both sides of the top of the sliding rail. This utility model, through the arrangement of the slide rail mechanism and the drive mechanism, allows the position of the electrical fire monitoring and alarm mechanism to be moved during monitoring, allowing it to slide along the slide rail. During this sliding process, air is drawn into the electrical fire monitoring and alarm mechanism for monitoring, thereby increasing the monitoring area. It also avoids the situation where smoke cannot enter through the smoke inlet far from the fan due to an excessively long air inlet pipe, making it easier to use.

[0003] However, when this utility model is in use, the two sides of the top of the sliding rail are fixedly connected with meshing teeth, and the surface of the moving wheel meshes with the top of the sliding rail, which makes it difficult for the moving wheel to turn, limits the monitoring area, and results in poor performance. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides an electrical fire monitoring and alarm device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrical fire monitoring and alarm device, comprising a C-shaped track, with multiple fixed rods fixedly mounted on the upper surface of the C-shaped track, and fixed members fixedly mounted on the upper ends of the fixed rods. A pair of movable boxes are disposed within the C-shaped track, and a pair of output shafts are rotatably connected to the side walls of the movable boxes. Support wheels are fixedly mounted on the outer ends of the output shafts, and the support wheels contact the inner bottom surface of the C-shaped track. A differential and a brake reduction motor are fixedly installed within the movable boxes. The drive end of the brake reduction motor is fixedly connected to the input end of the differential, and the output end of the differential is fixedly connected to the end of the output shaft. Four steering wheels are rotatably connected to the outer side of the upper surface of the movable boxes. A rotating shaft is connected to the bottom surface of the movable boxes, and a housing is fixedly connected to the lower ends of two rotating shafts. An air inlet is provided on the left side of the bottom surface of the housing. A motor is fixedly installed within the housing, and a fan is fixedly mounted on the drive shaft of the motor. The fan is located within the air inlet. A smoke detector is installed within the housing, and a camera is installed on the bottom surface of the housing.

[0006] Preferably, an air outlet is provided on the upper right wall of the chassis.

[0007] Preferably, a fixing screw is inserted into the fixing member.

[0008] Beneficial effects:

[0009] This utility model provides an electrical fire monitoring and alarm device, which has the following beneficial effects:

[0010] The fan draws outside air into the chassis through the air inlet. A smoke alarm detects the smoke content in the air and sounds an alarm when the smoke content is too high. A camera allows for video viewing of the alarm area. The rotating support wheels move the mobile box along a C-shaped track. When turning, the steering wheels allow the mobile box to rotate at different angles. A differential allows the inner and outer support wheels to rotate at different speeds, facilitating the turning of the alarm device and thus expanding the monitoring area.

The smoke alarm 12 can detect the smoke content in the air, thereby judging whether a fire has occurred. When the smoke content is too high, the smoke alarm 12 will sound an alarm. The alarm area can be viewed by the camera 7. Starting the brake reduction motor 16 can drive the two output shafts 14 to rotate, and the rotation of the output shafts 14 can drive the support wheels 4 to rotate. The rotation of the support wheels 4 can drive the moving box 3 to move along the C-shaped track 1. When turning, the angle of the moving box 3 can be rotated by the steering wheel 2. The differential 15 can make the inner support wheel 4 and the outer support wheel 4 rotate at different speeds, which facilitates the turning of the alarm device and thus expands the monitoring area.
