Once a fire occurs, it can give an early alarm and extinguish the fire in the initial stage.

[0003] The fire detectors in the prior art are installed at fixed positions, with limited detection ranges and low utilization rates. If a fire occurs, the fire detectors near the fire occurrence position detect the fire, but they cannot avoid it. The high-temperature fire environment is likely to cause the fire detectors to be burned or damaged, and the later maintenance is cumbersome and costly. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] It should be noted that the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs; the terms used in the description of the present invention herein are only for the purpose of describing specific implementation manners and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0037] As Figures 1 to 5 shown, the present invention includes two C-shaped transverse frames 1 arranged oppositely and installed at the bottom of the building roof slab and a longitudinal sliding rod 3 arranged between the two C-shaped transverse frames 1. The end of the longitudinal sliding rod 3 is matched with the C-shaped transverse frame 1 through a transverse sliding mechanism 2. A longitudinal sliding mechanism 4 is arranged on the longitudinal sliding rod 3, and a fire detector 5 is installed at the bottom of the longitudinal sliding mechanism 4;

[0038] The longitudinal sliding mechanism 4 includes a sliding connection block 43 installed on the longitudinal sliding rod 3. A longitudinal motor 41 is arranged at the top of the sliding connection block 43. A driving wheel 411 is installed on the output shaft of the longitudinal motor 41. Two pressing rods 412 for pressing the transmission belt 42 are arranged at one end of the output shaft of the longitudinal motor 41 and are respectively located on both sides of the output shaft. Both ends of the transmission belt 42 are respectively connected to the two transverse sliding mechanisms 2. The belt section of the transmission belt 42 between the two pressing rods 412 is laid on the driving wheel 411.

[0039] It should be noted that two C-shaped transverse frames which are oppositely arranged and installed at the bottom of the building roof support the entire detection structure. The transverse frame meets the lateral movement range of the fire detector, and the longitudinal sliding rod meets the longitudinal movement range of the fire detector. By means of the rolling of the moving wheel on the rack, the sliding connecting plate is driven to slide on the sliding frame, thereby driving the change of the position of the longitudinal sliding frame. The longitudinal sliding device makes the longitudinal sliding mechanism slide on the longitudinal sliding frame by means of the transmission of the transmission belt, so that the fire detector has a wide movement range and a large detection range. The end of the longitudinal sliding rod is matched with the C-shaped transverse frame through the transverse sliding mechanism. The transverse sliding mechanism moves along with the longitudinal sliding rod. The fire detector is installed at the bottom of the longitudinal sliding mechanism. The longitudinal sliding mechanism moves along the longitudinal sliding rod. When a fire occurs, the transverse sliding mechanism, the longitudinal sliding rod, the longitudinal sliding mechanism and the fire detector as a whole avoid the fire occurrence position, avoiding the fire high-temperature environment from burning or damaging the fire detector. There is no need for maintenance in the later stage or only the transverse frame needs to be maintained.

[0040] In this embodiment, a rack 12 is arranged on the upper surface of the lower plate of the C-shaped transverse frame 1, and limit blocks 11 are arranged on the inner surfaces of the upper and lower plates of the C-shaped transverse frame 1 outside the rack 12.

[0041] In this embodiment, the transverse sliding mechanism 2 includes a sliding connecting plate 22. Sliding grooves 221 adapted to the limit blocks 11 are formed at the upper and lower ends of the sliding connecting plate 22. A transverse motor 21 is fixedly connected to the outer side surface of the sliding connecting plate 22 through a first bolt 24. The output shaft of the transverse motor 21 passes through the sliding connecting plate 22 and is connected with a moving wheel 23. The moving wheel 23 includes a roller 231 and a gear 232 arranged on the rolling surface of the roller 231 and cooperating with the rack 12. A through hole 222 for the longitudinal sliding rod 3 to pass through is arranged on the sliding connecting plate 22. One end of the longitudinal sliding rod 3 passing through the through hole 222 is provided with a connecting flange 31. The connecting flange 31 is fixedly connected with the sliding connecting plate 22 through a plurality of second bolts 32.

[0042] In this embodiment, a connecting support 223 for connecting the transmission belt 42 is arranged on the sliding connecting plate 22 above the through hole 222.

[0043] In this embodiment, both ends of the transmission belt 42 are provided with connecting heads 421. The central position of the connecting head 421 is a hollow structure. A connecting shaft 44 is arranged in the connecting head 421. Both ends of the connecting shaft 44 are connected with the connecting support 223. The bottom plate of the longitudinal motor 41 is fixedly connected with the sliding connecting block 43 through a plurality of third bolts 431. A connecting hole 432 for the longitudinal sliding rod 3 to pass through is arranged on the sliding connecting block 43.

[0044] It should be noted that the conveyor belt 42 is fixed on the sliding connection plate 22 by means of connectors placed at both ends of itself. By setting the pressing rod 412, the conveyor belt 42 is tightly pressed on the driving wheel 411. When the longitudinal motor 41 is started, the longitudinal motor 41 drives the driving wheel 411 to rotate. The driving wheel 411 makes the sliding connection block 43 slide on the longitudinal sliding frame 3 by means of the friction force between it and the conveyor belt 42.

[0045] In this embodiment, the fire detector 5 includes a mounting flange 51 connected to the bottom of the sliding connection block 43. The periphery of the mounting flange 51 is fixedly connected to the bottom of the sliding connection block 43 by a plurality of fourth bolts 53. A pan-tilt 52 is provided at the bottom of the mounting flange 51. An installation block 521 for installing an infrared flame detector 54 and a camera is provided on the pan-tilt 52. A light-transmitting protective cover 55 plated with a fireproof coating is provided outside the infrared flame detector 54, the camera and the installation block 521. The infrared flame detector 54 is fixedly connected to the installation block 521 through a detector connection terminal 541.

[0046] When the present utility model is in use, the transverse motor 21 and the longitudinal motor 41 are started to drive the infrared flame detector 54 to conduct a fire inspection in the detection area. If a fire occurs and generates infrared rays, the infrared flame detector 54 detects abnormal infrared rays, triggers the fire warning system, and prompts the personnel in the field to leave. The camera observes the location where the fire occurs, and the transverse motor 21 and the longitudinal motor 41 drive the infrared flame detector 54 away from the location where the fire occurs. At the same time, the light-transmitting protective cover 55 plated with a fireproof coating can effectively isolate the flame and heat.

[0047] The above are only the preferred embodiments of the present utility model, and do not impose any limitations on the present utility model. Any simple modifications, changes and equivalent structural changes made to the above embodiments according to the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
