[0004] 1. Although some helmets have long brims for sun protection, when the brims are only set in front of the worker, they can only provide sun protection for the worker's face, and the sun protection effect is poor; when the brims are set in a circle, although it can provide better sun protection, it increases the overall weight of the helmet, which is not convenient for use in construction processes where workers rarely turn their bodies;

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The multifunctional fan-shaped plate of the present invention provides sunshade for the workers, preventing the direct sunlight from shining on their skin. When performing pipeline installation, cement head installation and cement slurry mixing, the workers can insert another group of multifunctional fan-shaped plates into the connecting strip holes, so that the other group of multifunctional fan-shaped plates is located below the multifunctional fan-shaped plates. The two positioning balls and the spiral spring C are provided to limit the other group of multifunctional fan-shaped plates, making the two multifunctional fan-shaped plates more firmly connected. At this time, the transparent eye shield is located right in front of the workers' eyes, protecting the workers' eyes and face, and is suitable for construction processes such as debris splashing and mud splashing.

[0023] In addition, when performing the welding process, the worker can pull the welding protection plate on another set of multifunctional fan-shaped plates. At this time, the welding protection plate can overlap with the transparent goggles, which protects the eyes and face of the worker and is suitable for welding construction processes.

[0024] 2. The present invention facilitates the staff to insert a suitable number of multifunctional fan-shaped plates according to the current working situation. When the staff is currently in a process in which the body is less rotated, one, two or three multifunctional fan-shaped plates can be inserted. When the staff is currently in a process in which the body is more rotated, four, five or six multifunctional fan-shaped plates can be inserted. Under the premise of ensuring the sunshade effect, the number of multifunctional fan-shaped plates inserted is reduced as much as possible, which is conducive to reducing the weight on the head of the staff; when the staff's body rotates a certain angle and continues to work, the staff can rotate the connecting ring so that the multifunctional fan-shaped plates on the connecting ring can be aligned with the sunlight;

[0025] In addition, when the staff rotates the connecting ring, the movable positioning block can automatically move inward after being subjected to force. When the connecting ring stops rotating, the movable positioning block can automatically be inserted into the corresponding arc-shaped positioning groove A under the action of the spiral spring A. The setting of the movable positioning rod plays a positioning role for the multifunctional fan-shaped plate after insertion, making the multifunctional fan-shaped plate more stable after insertion.

[0026] 3. In the present invention, when the temperature sensor detects that the temperature inside the helmet body exceeds a preset temperature value, the controller can start the motor to rotate the exhaust impeller for a period of time, which is beneficial to increase the air flow rate at the head of the worker and cool the head of the worker. In addition, because the photovoltaic power generation panel is fixedly installed on the flip flat plate and the photovoltaic power generation panel is electrically connected to the battery, the battery is charged.

[0027] In addition, when the workers are currently in a construction area with fewer falling objects from high altitudes, they can rotate the flip plate counterclockwise to allow the photovoltaic panels to come into contact with sunlight. When the workers are currently in a construction area with more falling objects from high altitudes, they can rotate the flip plate clockwise to place the photovoltaic panels under the flip plate, thereby protecting the photovoltaic panels and reducing the probability of damage to the photovoltaic panels. The setting of three sets of supporting balls allows the temperature sensor to slide arbitrarily along the circular track, which is convenient for detecting the temperature at different positions and improves the temperature detection effect.

[0054] The specific function is as follows: since the outer wall of the connecting ring 201 is provided with six connecting slots 2012, it is convenient for the staff to insert a suitable number of multifunctional fan-shaped plates 301 according to the current working situation. When the staff is currently in a process in which the body is rotated less, one, two or three multifunctional fan-shaped plates 301 can be inserted. When the staff is currently in a process in which the body is rotated more, four, five or six multifunctional fan-shaped plates 301 can be inserted. Under the premise of ensuring the sunshade effect, the number of inserted multifunctional fan-shaped plates 301 is reduced as much as possible, which is conducive to reducing the weight on the head of the staff; and since the connecting ring 201 is rotatably installed on the outside of the helmet body 101, when the staff's body rotates a certain angle and continues to work, the staff can rotate the connecting ring 201 so that the multifunctional fan-shaped plates 301 on the connecting ring 201 can be aligned with the sunlight;

[0058] Its specific function is as follows: since the temperature sensor 509 is fixedly mounted on the T-shaped slider 507, and the temperature sensor 509 is electrically connected to the controller 503, and the controller 503 is electrically connected to the battery 502, when the temperature sensor 509 detects that the temperature inside the helmet body 101 exceeds the preset temperature value, the controller 503 can start the motor 403 to rotate the exhaust impeller 404 for a period of time, which is beneficial to increase the air flow rate at the head of the worker, and has a cooling effect on the head of the worker.
