[0041] The device, through the tilting mechanism 2, allows the solar panel 10 to tilt at an angle, enabling the device to maximize the power generation efficiency of the solar panel 10 under different light conditions. This, in turn, charges the built-in battery 13 and provides a stable power supply to the device's electrical appliances. Furthermore, the lifting mechanism 3 allows the noise detector 12 to be stored in the protective box 1, preventing damage to the internal electronic components of the noise detector 12 due to collisions or other reasons.
[0042] Reference Figure 1 , Figure 3 and Figure 4 The protective box 1 has four corners of the bottom surface with fixed sliding columns 306. The moving plate 301 is slidably connected to the sliding column 306. The drive gear 304 is meshed with the rack 305, so that the movement of the moving plate 301 can be limited by the sliding column 306.

[0049] Working principle: In use, the handle 5 facilitates carrying and transportation of the device. Rotating the handle 9 rotates the rotating rod 2011, causing the second bevel gear 209 to rotate. Through tooth meshing, the second bevel gear 208 rotates, thereby rotating the threaded rod 202. The threaded connection causes the moving block 203 to move with the rotation of the threaded rod 202, moving one end of the first hinge rod 204. This changes the position of the hinge connection between the first hinge rod 204 and the second hinge rod 205, allowing the first hinge rod 204 to support the second hinge rod 205, thus tilting the inclined plate 206. The solar panel 10 can be tilted at an angle so that it can face the direct sunlight, thereby improving the power generation efficiency of the solar panel 10. The solar panel 10 converts light energy into electrical energy and stores it in the battery 13 for storage and use. The dual-axis motor 302 drives the transmission rods 303 at both ends to rotate, causing the drive gear 304 to rotate. Through tooth meshing, the gear rotates and moves on the rack 305, driving the moving plate 301 to move upward, thereby moving the noise detector 12 out. The noise detector 12 can still be stored in the protective box 1 by rotating the dual-axis motor 302 in the opposite direction.
