[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, as Figures 1-4 As shown, the utility model provides a crane safety reminder projection device, comprising a fixing mechanism 1, and a projection mechanism 2 is fixedly installed between the outer walls of the fixing mechanism 1;

[0026] The projection mechanism 2 includes an instrument body 201, a processor 202 is provided on one side of the outer wall of the instrument body 201, an alarm 203 is provided on one side of the outer wall of the instrument body 201, a projection head 204 is provided on the top of the instrument body 201, a camera 205 is provided on the top of the instrument body 201, an electromagnetic controller 206 is fixedly installed on the top of the instrument body 201, a second motor 207 is fixedly installed on the top of the instrument body 201, a second shaft 208 is fixedly installed on the output end of the second motor 207, and a shell 209 is fixedly provided on the outer wall of the second shaft 208. A mounting hole 210 is provided at the top of the shell 209, and a cleaning brush 211 is movably inserted into the inner wall of the outer shell 209. A mounting groove 212 is provided at the top of the cleaning brush 211. A spring 213 is fixedly installed at the bottom of the inner wall of the mounting groove 212, and a block 214 is fixedly installed on the top of the spring 213. The inner wall of the mounting groove 212 and the outer wall of the block 214 are movably inserted, and the inner wall of the mounting hole 210 is movably inserted with a block 214. An iron core 215 is fixedly installed at the bottom of the cleaning brush 211, and the top of the iron core 215 is magnetically connected to the bottom of the electromagnetic controller 206.

[0027] The effect achieved by the entire embodiment 1 is that after the projection head 204 projects the relevant text or pattern, the camera 205 starts to monitor the area below. When the camera 205 detects that someone has entered the projected pattern, the processor 202 will activate the alarm 203, which will use a loud warning sound to remind people to stay away from the dangerous area in time, thereby reducing the possibility of accidents, and monitor the situation of operators around the crane in real time. When the surface of the projection head 204 and the camera 205 is contaminated with pollutants, the electromagnetic controller 206 starts to shut down, and then the motor 207 drives the housing 209 and the cleaning brush 203 through the rotating shaft 208. 11 rotates together to remove pollutants on the surfaces of the projection head 204 and the camera 205 to prevent the pollutants from affecting their normal operation. After cleaning is completed, the cleaning brush 211 drives the iron core 215 to return to its original position, and the electromagnetic controller 206 starts to start, fixing the cleaning brush 211 through the iron core 215 to prevent the cleaning brush 211 from moving due to external force, thereby blocking the projection head 204 and the camera 205. When the operator needs to clean or replace the cleaning brush 211, he only needs to press the block 214 to retract it into the installation slot 212, and then he can remove the cleaning brush 211, thereby improving the efficiency of cleaning or replacing it.

[0028] Example 2, as Figure 2-Figure 4 As shown, the fixing mechanism 1 includes a fixing frame 101, and two circular holes 102 are provided on the outer wall of the fixing frame 101. A rotating shaft 103 is movably inserted into the inner wall of the two circular holes 102. A motor 104 is fixedly installed on one side of the outer wall of the fixing frame 101, and the output end of the motor 104 is fixedly connected to one side of the outer wall of one of the two rotating shafts 103. The outer walls of the two rotating shafts 103 are fixedly connected to the outer wall of the instrument body 201.

[0029] The effect achieved by the entire embodiment 2 is that after the motor 104 is started, it will drive the instrument body 201 to rotate through the shaft 103, so that the device can adjust the projection direction according to specific requirements, improve its flexibility and applicability, reduce adjustment time, and improve projection efficiency.

[0030] Working principle: The operator can first install and fix the fixing frame 101 on the surface of the crane. When the projection device needs to be used, the motor 104 starts to start, driving the rotating shaft 103 to start rotating inside the circular hole 102. When the rotating shaft 103 rotates, it can drive the instrument body 201 to rotate together, so that it can adjust the projection direction according to specific requirements. After the direction of the instrument body 201 is confirmed, the projection head 204 will project the relevant text or pattern to the corresponding area, and then the camera 205 starts to start and monitor the area below. The picture monitored by the camera 205 will be transmitted to the processor 202. When the processor 202 finds that someone is approaching or entering the projection area, it will promptly activate the alarm 203. At this time, the alarm 203 will emit a loud warning sound to remind people to stay away from the dangerous area in time to avoid accidents. When the instrument is used When the projection head 204 and the camera 205 are used for too long, they will be contaminated with a lot of pollutants. At this time, the electromagnetic controller 206 starts to shut down, releasing the adsorption of the iron core 215, and the motor 207 starts to start, driving the shaft 208 to start rotating. When the shaft 208 rotates, it will drive the shell 209 to move together. The shell 209 will cause the cleaning brush 211 to rotate together, thereby removing the pollutants on the surface of the projection head 204 and the camera 205 to keep them clean. When the cleaning brush 211 drives the iron core 215 to move to the bottom of the electromagnetic controller 206, the electromagnetic controller 206 starts and fixes the position of the cleaning brush 211 through the iron core 215. When the cleaning brush 211 has been used for too long, the operator can press the block 214 to retract the compression spring 213 into the mounting slot 212, and the operator can remove the cleaning brush 211 for replacement or cleaning.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
