[0002] Smoke detectors, also known as smoke-sensing fire detectors, smoke detectors, smoke sensors, smoke probes, and smoke sensors, are mainly used in fire protection systems and are also used in security system construction.

[0003] Publication number CN213458405U mentions a large-space fire detector detection device. This device uses multiple downward-facing smoke inlets on the outer wall of a protective sleeve to isolate dust from the smoke inlets, allowing accumulated dust to roll out under gravity. This prevents damage to the smoke sensor and avoids blockage caused by dust accumulation. However, in large spaces, it cannot quickly detect dense smoke, leading to delayed alarms and rescue efforts, potentially causing injuries or fatalities. Furthermore, it cannot accurately pinpoint the location of the smoke, resulting in poor performance. Therefore, a large-space fire detector detection device is urgently needed to address these issues. Utility Model Content

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-4This utility model provides a technical solution: a large-space fire detector detection device, including a straight guide rail 1, a curved guide rail 2, a smoke detector 3, an electromagnetic acceleration mechanism 4, and an electromagnetic ejection mechanism 5. The curved guide rail 2 is installed on the side surface of the straight guide rail 1, the electromagnetic acceleration mechanism 4 is installed on the lower surface of the straight guide rail 1, the electromagnetic ejection mechanism 5 is installed on the lower surface of the electromagnetic acceleration mechanism 4, and the smoke detector 3 is installed on the lower surface of the electromagnetic ejection mechanism 5. The electromagnetic acceleration mechanism 4 includes an acceleration base 41, a magnet slot 42, an acceleration magnet 43, an electric sheet fixing block 44, and a conductive sheet 45. The acceleration base 41 is installed on the upper surface of the straight guide rail 1, and two magnet slots 42 are respectively installed at both ends of the lower surface of the acceleration base 41. Two acceleration magnets 43 are respectively installed inside the two magnet slots 42. The two ends of the lower surface of the acceleration base 41 are respectively Two electrode fixing blocks 44 are installed, and conductive plates 45 are installed on the side surfaces of the electrode fixing blocks 44. The electromagnetic catapult mechanism 5 includes a catapult top plate 51, a catapult base 52, a coil frame 53, an electromagnetic coil 54, a brush 55, a brush fixing groove 56, and a guide rail groove 57. The catapult base 52 is installed on the lower surface of the straight guide rail 1. The coil frame 53 is installed on the lower surface of the catapult base 52. The electromagnetic coil 54 is installed on the circumferential surface of the coil frame 53. The brush fixing groove 56 is installed on the lower surface of the catapult base 52. The brush 55 is installed on the inner side of the brush fixing groove 56. This design solves the problem that the original device cannot quickly detect the generated dense smoke when used in a large space, resulting in untimely alarm and rescue, which may cause casualties. It also cannot accurately detect the exact location of the smoke, resulting in poor performance during use.

[0019] As the first embodiment of this utility model: a straight support column 11 is installed on the upper surface of the straight guide rail 1 groove, a straight fixing plate 12 is installed on the upper surface of the straight support column 11, and a straight fixing bolt 13 is installed on the lower surface of the straight fixing plate 12; a curved support column 21 is installed on the upper surface of the curved guide rail 2 groove, a curved fixing plate 22 is installed on the upper surface of the curved support column 21, and a curved fixing bolt 23 is installed on the lower surface of the curved fixing plate 22; the outer surfaces of the two accelerating magnets 43 in the same magnet groove 42 have opposite polarities, and the outer surfaces of the two opposing accelerating magnets 43... With opposite polarities, the upper surface of the inner side of the acceleration base 41 is fixedly connected to the upper surface of the straight guide rail 1. The input and output ends of the electromagnetic coil 54 are respectively connected to two brushes 55 through wires. The outer surface of the brush 55 and the inner surface of the corresponding conductive sheet 45 are on the same plane. The width of the guide groove 57 is greater than the width of the straight guide rail 1 and the cross-sectional width of the curved guide rail 2. The straight guide rail 1 is located inside the guide groove 57. By making the width of the guide groove 57 greater than the cross-sectional width of the curved guide rail 2, the ejection base 52 will not experience any jamming when passing through the curved guide rail 2.

[0020] As a second embodiment of this utility model: During installation, sufficient straight guide rails 1, curved guide rails 2, and electromagnetic acceleration mechanisms 4 can be installed according to the available space. After splicing the straight guide rails 1 and curved guide rails 2, they are fixed to the ceiling using straight fixing bolts 13 and curved fixing bolts 23. Then, the electromagnetic acceleration mechanism 4 is fixed to the straight guide rails 1 with bolts. Before the straight guide rails 1 are installed, an electromagnetic catapult mechanism 5 is first strung along the guide rail groove 57 onto the straight guide rails 1, and the electromagnetic coil 54 is pushed between the four accelerating magnets 43. At this time, the conductive sheet 45 is in contact with the brush 55. After the straight guide rails 1, curved guide rails 2, electromagnetic acceleration mechanisms 4, and electromagnetic catapult mechanisms 5 are installed, direct current is applied to the two conductive sheets 45, causing the electromagnetic coil 54 to generate magnetic flux. The two accelerating magnets 43 near the brush 55 have the same polarity as one end of the adjacent electromagnetic coil 54, while the two accelerating magnets 43 away from the brush 55 have opposite polarities to one end of the adjacent electromagnetic coil 54. At this time, the accelerating magnet 43 at one end exerts a pushing force on the electromagnetic coil 54, and the accelerating magnet 43 at the other end exerts an attractive force on the electromagnetic coil 54. At the same time, the electromagnetic ejection mechanism 5 will rush out of the electromagnetic acceleration mechanism 4. After the electromagnetic ejection mechanism 5 rushes out, the brush 55 separates from the conductive sheet 45, and the electromagnetic coil 54 will lose power and lose its magnetism. It will slide on the straight guide rail 1 and the curved guide rail 2. Before losing power, it will pass through the electromagnetic acceleration mechanism 4 again, so that the electromagnetic ejection mechanism 5 can regain kinetic energy, thereby enabling the smoke sensor to move continuously in space and detect more space.
