[0032] refer to Figure 4 The back of the transmission rod 28 is fixedly connected with the sliding column 5, and the back of the sliding column 5 is slidably connected with the inner wall of the power box 21.

[0033] As a technical optimization solution of the utility model, the setting of the sliding column 5 can limit the transmission rod 28, ensuring that it can run on the specified track, avoiding the situation where the transmission rod 28 is positionally offset and causing the overall structure to be unusable, thereby effectively protecting the integrity of the structure, extending the service life of the overall structure, and enabling it to operate more stably.

[0034] refer to Figure 5 The top of the transmission rod 28 is fixedly connected with a connecting plate 6 , and the outer side of the connecting plate 6 is fixedly connected to the inner side of the protective plate 29 .

[0035] As a technical optimization solution of the utility model, the setting of the connecting plate 6 can reinforce the transmission rod 28, strengthen the connectivity between the transmission rod 28 and the protective plate 29, avoid the transmission rod 28 and the protective plate 29 from breaking and falling off during long-term operation, effectively protect the integrity of the structure, and extend the service life of the structure.

[0036] The working principle and usage process of the utility model are as follows: first, the user only needs to start the motor 22 in the power box 21, the output end of the motor 22 drives the threaded rod 23 to rotate, the threaded rod 23 drives the transmission screw block 24 to move, the transmission screw block 24 drives the transmission belt 26 to move, the transmission belt 26 drives the transmission rod 28 to move, and the transmission rod 28 drives the protective plate 29 to move to a state of completely covering the alarm speaker 12, thereby achieving the effect of protecting the alarm from being damaged by external factors and unable to be used normally.

[0037] To sum up: the protective structure of the forestry fire alarm, by setting up a protective mechanism, changes the situation where traditional forestry fire alarms will be affected by external factors such as animals and plants when working in the field, causing the device to be damaged and unable to be used normally. It can protect it so that it can operate stably for a long time and prevent serious consequences caused by failure to issue an alarm in time in the event of an emergency.
