Description

Technical Field

[0001] The utility model belongs to the technical field of fire detection, and more specifically relates to a detector for fire protection. Background Art

[0002] The main work of firefighting includes rescue at the fire scene. With the continuous development of firefighting equipment, more and more new firefighting equipment are also applied to firefighting work, such as fire monitoring equipment with smoke detectors;

[0003] Traditional smoke fire sensor detectors are generally installed on the ceiling of a room to detect whether there is a fire in the room; therefore, the fire detector is too high to be cleaned, and dust will accumulate on the detector after a long time. The dusty detector will affect the detector's sensitivity to smoke during use, affecting the use of the detector; however, due to the high height, it is impossible to clean it, and using a ladder to clean it up also poses a safety hazard and causes operational changes; therefore, a fire detector is proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a fire-fighting detector, which can realize convenient cleaning of the detector without climbing up.

[0005] The utility model discloses a fire detector, comprising a base, a detector body and a rotating frame; the detector is fixedly mounted on the lower end surface of the base; the rotating frame is rotatably mounted on the detector body, a brush is arranged on the rotating frame, the brush abuts against the surface of the detector body; a plurality of blades are arranged along the circumferential direction on the lower end surface of the rotating frame.

[0006] As a further improvement of the utility model, the rotating frame includes a chassis and a bracket; the chassis is rotatably connected to the lower end of the detector body; the bracket is rotatably mounted on the upper end surface of the chassis along the circumferential direction; and the brush is fixedly mounted on the inner end surface of the bracket.

[0007] As a further improvement of the utility model, a slide groove is arranged on the lower end surface of the base; a sliding block matched with the slide groove is arranged on the upper end of the bracket, and the sliding block is slidably installed in the slide groove.

[0008] As a further improvement of the present invention, the slide groove is provided with a slot.

[0009] As a further improvement of the utility model, a sleeve is fixedly installed on the lower end surface of the detector body; the chassis is movably mounted on the sleeve, and a limit cover is installed on the sleeve through threads, and the outer wall diameter of the limit cover is larger than the inner hole diameter of the chassis.

[0010] Compared with the prior art, the advantages of the present invention are:

[0011] The utility model is provided with a rotating frame, and the rotating frame can be driven to rotate by blowing blades, thereby driving the brush to clean the surface of the detector body to avoid the problem of dust accumulation. The detector can be cleaned by only blowing air upwards through the hair dryer to drive the blades to rotate, without the need to climb high, which is safer and more convenient.
