Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire alarm technology, specifically a fire alarm device for floor fire alarm. Background Technology
[0002] Fire alarm refers to a series of processes and technical means that use specific devices or systems to monitor various characteristic signals (such as smoke, abnormal temperature rise, flames, etc.) generated when a fire occurs, and to issue an alarm signal in a timely manner when fire signs are detected, so as to remind people of the occurrence of a fire and thus buy valuable time for emergency measures such as personnel evacuation and fire fighting.
[0003] However, in practical use, existing fire alarm systems typically have fixed installations for alarm devices, making it difficult to move and adjust them according to actual usage or changes in spatial layout. In actual buildings, the functions of different areas may change, or there may be temporary zoning. This can cause fixed-installation alarm devices to fail to detect fires in a timely and accurate manner and issue alarms. For example, in some large shopping malls, the layout of shops is adjusted regularly, and the original alarm devices may not be able to cover new high-risk areas. Or in industrial plants, the movement of production equipment may cause certain areas to become potential fire hazards, but fixed-installation alarm devices cannot adapt to these changes in a timely manner. Utility Model Content
[0004] The purpose of this utility model is to provide a fire alarm device for floor fire alarm, in order to solve the problem mentioned in the background art that the location of the alarm device in the existing floor fire alarm system is usually fixed and it is difficult to move and adjust according to the actual use or changes in spatial layout. However, in actual buildings, the functions of different areas may change, or there may be some temporary zoning, which leads to the problem that the fixed alarm device may not be able to detect the occurrence of fire and issue an alarm in a timely and accurate manner.
[0005] To achieve the above objectives, the present invention provides the following technical solution: including a mounting top plate and a movable seat, wherein a horizontal limiting slide rail is fixedly installed at the bottom of the mounting top plate, limiting slide grooves are fixedly installed on both sides of the upper end of the movable seat, a transmission opening is provided through the outer side of the movable seat, a first drive motor is fixedly installed on the lower outer side of the movable seat, a first transmission gear is fixedly installed on the inner transmission shaft of the first drive motor, and a transmission rack is meshed with the upper end of the first transmission gear;
[0006] A second drive motor is fixedly mounted on the outer side of the lower end of the movable base. A second transmission gear is fixedly mounted on the upper transmission shaft of the second drive motor. A transmission gear ring is meshed with the inner side of the second transmission gear. A rotating seat is fixedly mounted in the middle of the transmission gear ring. An L-shaped extension frame is fixedly mounted on the lower end of the rotating seat. An electric telescopic rod is fixedly mounted through the middle of the lower end of the L-shaped extension frame. An L-shaped mounting plate is fixedly mounted on the telescopic part of the lower end of the electric telescopic rod. A smoke sensor and an audible and visual alarm are fixedly mounted on the lower end of the L-shaped mounting plate. An emergency guide light is fixedly mounted on the outer side of the L-shaped mounting plate.
[0007] Preferably, a mobile control power supply is fixedly installed at the middle of the upper end of the mobile base.
[0008] Preferably, the mounting top plate has a through-hole on its outer side, and there are several mounting holes, which are symmetrically distributed on the outer side of the mounting top plate.
[0009] Preferably, there are two limiting grooves, which are symmetrically distributed on both sides of the upper end of the movable seat, and the inner side of the limiting groove is movably connected to the lower end of the horizontal limiting slide rail.
[0010] Preferably, the transmission rack is fixedly installed on the inner side of the lower end of the mounting top plate.
[0011] Preferably, the rotating seat is rotatably connected to the lower middle part of the movable seat via a rotating shaft.
[0012] Preferably, limiting slide rods are fixedly installed on both sides of the upper end of the L-shaped mounting plate, and the upper ends of the limiting slide rods are movably connected through and fitted to both sides of the lower end of the L-shaped extension frame.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] When the second drive motor is turned on, the rotating seat will rotate, which in turn will rotate the L-shaped extension frame. When the L-shaped extension frame rotates, it will rotate the emergency indicator light to adjust its position. At the same time, the electric telescopic rod will be activated. When the electric telescopic rod is activated, it will move the L-shaped mounting plate vertically. When the L-shaped mounting plate moves vertically, it will simultaneously move the smoke sensor, audible and visual alarm, and emergency indicator light vertically. This allows for both fire alarm activation and easy vertical adjustment of the alarm and emergency indicator positions.
[0015] This invention also features a first drive motor that, when turned on, drives the first transmission gear to rotate. When the first transmission gear rotates, the force generated by the meshing connection between the upper end of the first transmission gear and the transmission rack drives the movable seat to move back and forth in a straight line. When the movable seat moves back and forth in a straight line, it simultaneously drives the smoke sensor, the audible and visual alarm, and the emergency guide light to move back and forth in a straight line. This enables fire alarm while facilitating the adjustment of the alarm and emergency indication positions by moving back and forth in a straight line. Attached Figure Description

[0021] Please see Figure 1-3 This utility model provides a technical solution for a fire alarm device for floor fire alarm: including a mounting plate 1 and a movable base 2, and a movable control power supply is fixedly installed in the middle of the upper end of the movable base 2;
[0022] The mounting top plate 1 has several mounting holes 3 through its outer side, which are symmetrically distributed on the outer side of the mounting top plate 1. The mounting top plate 1 is fixed by mounting bolts through the mounting holes 3. A horizontal limiting slide rail 4 is fixedly installed at the bottom of the mounting top plate 1. Two limiting slide grooves 5 are fixedly installed on both sides of the upper end of the movable seat 2, which are symmetrically distributed on both sides of the upper end of the movable seat 2. The inner side of the limiting slide groove 5 is movably connected to the lower end of the horizontal limiting slide rail 4, so that the movable seat 2 can be linearly limited by the limiting slide groove 5 and the horizontal limiting slide rail 4. A transmission opening 6 is through its outer side of the movable seat 2. A first drive motor 7 is fixedly installed on the outer side of the lower end of the movable seat 2. A first transmission gear 8 is fixedly installed on the transmission shaft part of the first drive motor 7. A transmission rack 9 is meshed with the upper end of the first transmission gear 8, and the transmission rack 9 is fixedly installed on the inner side of the lower end of the mounting top plate 1.
[0023] A second drive motor 10 is fixedly mounted on the outer side of the lower end of the movable base 2. A second transmission gear 11 is fixedly mounted on the transmission shaft of the upper end of the second drive motor 10. A transmission gear ring 12 is meshed with the inner side of the second transmission gear 11. A rotating base 13 is fixedly mounted in the middle of the transmission gear ring 12, and the rotating base 13 is rotatably connected to the middle of the lower end of the movable base 2 through a rotating shaft. An L-shaped extension frame 14 is fixedly mounted on the lower end of the rotating base 13. An electric telescopic rod 15 is fixedly mounted through the middle of the lower end of the L-shaped extension frame 14. An L-shaped mounting plate 16 is fixedly mounted on the telescopic part of the lower end of the electric telescopic rod 15. Limiting slide rods are fixedly mounted on both sides of the upper end of the L-shaped mounting plate 16, and the upper ends of the limiting slide rods are movably connected through and fitted to both sides of the lower end of the L-shaped extension frame 14, so that the L-shaped mounting plate 16 can be linearly limited by the limiting slide rods. A smoke sensor 17 and an audible and visual alarm 18 are fixedly mounted on the lower end of the L-shaped mounting plate 16. An emergency guide light 19 is fixedly mounted on the outer side of the L-shaped mounting plate 16.
[0024] Working Principle: In use, this utility model uses a smoke sensor 17 and an audible and visual alarm 18 to detect smoke and provide audible and visual alarms for fires. An emergency guide light 19 guides emergency exits. The second drive motor 10 is activated, driving the second transmission gear 11 to rotate. This gear meshes with and drives the transmission ring 12, which in turn rotates the rotating seat 13. This rotation, in turn, drives the L-shaped extension frame 14, which in turn rotates the emergency guide light 19 to adjust its position. Simultaneously, the electric telescopic rod 15 is activated, causing the L-shaped mounting plate 16 to move vertically. This vertical movement of the L-shaped mounting plate 16 synchronously moves the smoke sensor 17, the audible and visual alarm 18, and the emergency guide light 19 vertically, thus enabling both fire alarm and convenient vertical adjustment of the alarm and emergency indication positions.
[0025] Simultaneously, by controlling the activation of the first drive motor 7, the first drive motor 7 will drive the first transmission gear 8 to rotate. When the first transmission gear 8 rotates, the force generated by the meshing connection between the upper end of the first transmission gear 8 and the transmission rack 9 will drive the movable seat 2 to move back and forth in a straight line. When the movable seat 2 moves back and forth in a straight line, it will simultaneously drive the smoke sensor 17, the audible and visual alarm 18, and the emergency guide light 19 to move back and forth in a straight line. This enables fire alarm while facilitating the adjustment of the alarm and emergency indication positions by moving back and forth in a straight line.
