[0021] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0022] The first implementation method:

[0023] Figure 1-6 The present invention provides a smoke alarm device for use in a cable room of a substation, comprising a base 1, a circular plate 2 being provided at the upper end of the base 1, a vertical pipe 3 being fixedly connected to the lower end of the circular plate 2, a motor 7 being fixedly connected to the inner bottom wall of the base 1, and those skilled in the art can make the best choice of the model of the motor 7, such as model Y80M1-2, the telescopic end of the motor 7 being fixedly connected to the lower end of the vertical pipe 3, the upper end of the circular plate 2 being fixedly connected to a fixed plate 4, the upper end of the fixed plate 4 being fixedly connected to an air pump 5, and those skilled in the art can make the best choice of the model of the air pump 5, such as model 2BV, the air outlet end of the air pump 5 being fixedly connected to an outer tube 11 communicating therewith, an inner tube 6 being movably inserted into the interior of the outer tube 11, and the outer wall of the inner tube 6 and the inner wall of the outer tube 11 being in a sliding and sealing state, the end of the inner tube 6 away from the outer tube 11 being fixedly connected to a smoke sensor 10, the outer end of the smoke sensor 10 being fixedly connected to a controller 12, and the upper end of the smoke sensor 10 being fixedly connected to a warning light 13 and an alarm bell 14;

[0024] A warning light 13 and an alarm 14 are fixedly connected to the upper end of the smoke sensor 10. Both the warning light 13 and the alarm 14 are electrically connected to the controller 12 via wires. A pair of mounting holes are provided on the base 1. The smoke sensor 10 is electrically connected to the controller 12 via wires. A pair of sliders 8 are fixedly connected to the outer end of the inner tube 6. The sliders 8 can limit the inner tube 6 to prevent it from separating from the outer tube 11. A pair of slide grooves 9 are provided on the inner wall of the outer tube 11 and are movably inserted into the sliders 8.

[0025] The use of this device is divided into the following steps:

[0026] Step 1: During installation, turn the device over so that the smoke sensor 10 faces downward, and use bolts to fix the base 1 to the ceiling of the house or the mounting frame;

[0027] Step 2: Remote lateral detection: Start the air pump 5 to inflate the outer tube 11, increase the pressure in the outer tube 11, and use the gas to push the inner tube 6 out of the outer tube 11 (combined with Figure 4 As shown in FIG. 1 , when the inner tube 6 moves, it drives the smoke sensor 10 to move away from the outer side of the circular plate 2, thereby adjusting the distance between the smoke sensor 10 and the circular plate 2, expanding the detection range, and improving the timeliness of detection. When the smoke sensor 10 detects fire smoke, the controller 12 activates the warning light 13 and the alarm 14, emitting sound and light signals to notify personnel to come and deal with the fire;

[0028] Step 3: Remote Circumferential Detection: After moving the smoke sensor 10 horizontally, the motor 1 7 can be started, so that its output end drives the vertical tube 3 and the circular plate 2 to rotate together, thereby causing the smoke sensor 10 to perform circular motion in the horizontal direction. The smoke sensor 10 can detect smoke in different areas, further optimizing the timeliness of smoke detection.

[0029] In summary, when the present invention is in use, the thrust of the gas pushes the inner tube 6 out of the outer tube 11, causing the smoke sensor 10 to move outward away from the circular plate 2, thereby expanding the detection range of the smoke sensor 10. At the same time, the motor 17 causes the vertical tube 3 to drive the circular plate 2 and the smoke sensor 10 to rotate together in a horizontal direction, thereby further expanding the detection range and optimizing the speed and timeliness of detection.

[0030] When the present application is not in use, the gas in the outer tube 11 can be extracted through the air pump 5, and the inner tube 6 can be retracted into the interior of 11 by the negative pressure, thereby reducing the volume of the present application and making it convenient to carry and store.

[0031] The second implementation method:

[0032] This embodiment adds the following structure based on the first embodiment, and the rest of the structure remains the same as the first embodiment, as follows:

[0033] Figure 1 and Figure 2 It is shown that the upper end of the smoke sensor 10 is fixedly connected to a vertical plate 15, and the side end of the vertical plate 15 is fixedly connected to a second motor 16. Those skilled in the art can make the best selection of the model of the second motor 16, such as model Y80M1-2. A reflector 17 is fixedly connected to the telescopic end of the second motor 16.

[0034] When in use, the light emitted by the warning light 13 will hit the reflector 17. The surface of the reflector 17 is provided with irregular textures, which will produce a diffuse reflection effect, so that the light source is softened and diffused to a larger area, thereby improving the visibility of the light and expanding the range of light propagation, making the emitted warning light signal easier to be discovered by personnel. At the same time, the motor 2 16 can be started so that its output end drives the reflector 17 to rotate to adjust the direction of light propagation, making it easier for personnel to be discovered.

[0035] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
