Description

Technical Field

[0001] The utility model relates to a fire detection alarm device, in particular to an intelligent fire alarm device. Background Art

[0002] Fire refers to a disaster caused by burning out of control in time or space. In the new standard, fire is defined as burning out of control 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 not only causes property losses, but is also likely to cause physical and psychological harm, so it is necessary to prevent fires. By setting up fire alarm equipment to detect fires in time and alarm, fires can be extinguished in the bud and potential safety hazards can be reduced. Fire alarm equipment is equipped with multiple sets of sensors, including smoke sensors, temperature sensors, etc. In order to detect the fire point in time, infrared sensors and cameras are installed on existing fire alarm equipment to find the fire point through infrared sensors and cameras.

[0003] For example, the patent with application number 202223169133.0 discloses a multifunctional detector for building fire detection, which is designed with a rotating mechanism composed of a motor, a gear ring, a gear, a limit groove and a convex ridge. During the detection process of the device, the limit groove and the convex ridge are combined to support and limit the gear ring. At the same time, the motor drives the gear to rotate, and the gear drives the infrared camera to rotate through the gear ring, so that it can detect smoke in the detection space in all directions. It can realize the circumferential rotation of the infrared camera, and the upper and lower positions of the infrared camera cannot be adjusted, which is easy to produce the phenomenon of dark under the light, that is, an area under the sleeve cannot be well detected.

DETAILED DESCRIPTION

[0012] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0013] Embodiment. A fire intelligent alarm device, comprising: Figure 1 As shown, it includes a fixed plate 1, a support cover 2 is provided under the fixed plate 1, a lower support seat 3 which can rotate relative to the support cover 2 is provided in the support cover 2, a first motor 6 which drives the lower support seat 3 to rotate is provided in the support cover 2, a connecting block 7 is provided at the lower end of the output shaft of the first motor 6, and a limit block 17 is provided on the inner wall of the support cover 2; a mounting groove 8 is opened in the middle of the lower end of the lower support seat 3, an infrared camera 9 is provided in the mounting groove 8, a second motor 10 which drives the infrared camera 9 to rotate is provided on one side of the mounting groove 8, and a smoke sensor 11, a temperature sensor 12 and an alarm 13 are provided on the other side of the mounting groove 8.

[0014] The infrared camera 9 is provided with mounting rods 15 on both sides, and a driving wheel 14 is provided on the mounting rod 15 on one side. The end of the mounting rod 15 with the driving wheel 14 is connected to the driving shaft of the second motor 10, and a gear ring 16 corresponding to the driving wheel 14 is provided on the side of the infrared camera 9.

[0015] A connecting seat 4 corresponding to the connecting block 7 is disposed on the upper side of the lower supporting seat 3 , and a limiting groove 5 corresponding to the limiting block 17 is disposed on the upper side wall of the lower supporting seat 3 .

[0016] The side wall of the support cover 2 is provided with heat dissipation holes 18 .

[0017] The principle of the utility model is as follows: the utility model is fixed on the ceiling by a fixing plate 1 and connected to an external power supply. When the smoke sensor 11 is used to detect the smoke signal, the temperature sensor 12 is used to detect the temperature change, and the signal is transmitted to the controller through the data transmission device. When the signal change reaches the threshold in a short time, the alarm 13 is triggered to remind the staff. The alarm uses the existing alarm with wireless communication function, which can send information to the staff. The staff judges whether there is a fire point through the infrared camera 9, whether it is a false alarm caused by sensor failure, and the location of the fire point can be quickly found through the infrared camera 9, which is convenient for accurate fire extinguishing. The shooting range of the infrared camera 9 is limited, so the camera position needs to be adjustable to realize multi-angle shooting detection. The utility model realizes that the first motor 6 drives the lower support seat 3 to rotate through the connection block 7 on the first motor 6 and the connection seat 4. The outer side wall of the upper end of the lower support seat 3 is provided with a limit groove 5, and the support cover 2 is provided with a limit block 17 corresponding to the limit groove 5, so that the lower support seat 3 can rotate relative to the support cover 2 without separation and falling off. In order to further increase the detection range, the present application fixes the infrared camera 9 through a mounting rod 15, and arranges a driving wheel 14 on one side of the mounting rod 15, and drives the infrared camera 9 to rotate through the cooperation of the driving wheel and the gear ring 16. The driving wheel 14 is driven by a second motor 10 arranged on the other side of the mounting groove 8, thereby avoiding blind spots on the lower side of the infrared camera and poor detection effect.
