[0022] Example 1
[0023] A photoelectric sensor protection device, such as Figure 1-Figure 6 As shown, it includes a sensor 1, a connecting line 101, a main box 2, a connecting hole plate 201, a square rotating plate 3, a small torsion spring 301, a shock absorbing mechanism, a heat dissipation mechanism and a fixing mechanism. The sensor 1 is slidably connected inside the main box 2 (the picture has been modified), the connecting line 101 is fixedly connected to the bottom of the sensor 1, the upper and lower parts of the outer side of the main box 2 are fixedly connected to the connecting hole plate 201, the bottom of the main box 2 is rotatably connected to a pair of square rotating plates 3, a pair of small torsion springs 301 are fixedly connected between the square rotating plates 3 and the main box 2, the main box 2 is provided with a shock absorbing mechanism, the main box 2 is provided with a heat dissipation mechanism, and the main box 2 is provided with a fixing mechanism.
[0024] like Figure 2 and Figure 4 As shown, the shock absorbing mechanism includes a protective shell 4, a connecting tube 5, a ball 501 and a reset spring 502. The protective shell 4 is fixedly connected to the inside of the main box 2. A plurality of connecting tubes 5 are slidably connected to the left and right sides and the rear side of the protective shell 4. The ball 501 is rotatably connected to the connecting tube 5. A reset spring 502 is fixedly connected between the connecting tube 5 and the main box 2. When the sensor 1 contacts and moves with the ball 501, it will drive the ball 501 to rotate.
[0025] like Figure 3 and Figure 4 As shown, the heat dissipation mechanism includes a mounting shell 6, a fan 7, a circular rotating plate 8, a motor 9, a heat pipe 10 and a connecting long tube 11. The mounting shell 6 is fixedly connected to the top of the main box 2. The mounting shell 6 is rotatably connected to the inside of the longitudinally distributed fan 7, and the fan 7 is used to dissipate heat for the sensor 1. The mounting shell 6 is rotatably connected to the circular rotating plates 8 on both the upper and lower sides. The motor 9 is fixedly connected to the upper and lower parts of the left side of the mounting shell 6. The output end of the motor 9 is fixedly connected to the circular rotating plate 8. The heat pipe 10 is fixedly connected to the rear side of the main box 2. The connecting long tube 11 is fixedly connected to the top of the main box 2. One end of the heat pipe 10 is connected to the external air, and the other end of the heat pipe 10 is connected to one end of the connecting long tube 11 (the figure has been modified), and the other end of the connecting long tube 11 is connected to the protective shell 4, and the connecting long tube 11 is fixedly connected to the mounting shell 6.
[0026] like Figure 5 and Figure 6 As shown, the fixing mechanism includes a rounded corner column 12, a large round head plate 13, a vertical torsion spring 14 and a round head plate frame 15. The bottom of the main box 2 is rotatably connected to the rounded corner column 12, the large round head plate 13 is fixedly connected to the front side of the rounded corner column 12, and the vertical torsion spring 14 is fixedly connected between the rounded corner column 12 and the main box 2. The bottom of the main box 2 is slidably connected to the round head plate frame 15, the round head plate frame 15 is slidably connected to the large round head plate 13, the round head plate frame 15 is used to limit the rotation of the large round head plate 13, the large round head plate 13 is in contact with the paired square rotating plates 3, and the large round head plates 13 are used to resist the paired square rotating plates 3 so that the paired square rotating plates 3 cannot rotate downward.
[0027] When people need to use the photoelectric sensor, first fix the main box 2 on the wall or other instrument rack through the connecting hole plate 201, then pull the round head plate frame 15 downward until it is separated from the large round head plate 13, and then rotate the large round head plate 13 and the rounded corner column 12 clockwise until the large round head plate 13 is separated from the paired square rotating plates 3, and the vertical torsion spring 14 is deformed immediately, and then the sensor 1 and the connecting line 101 are moved upward from the bottom of the main box 2, and the paired square rotating plates 3 are squeezed by the sensor 1 and rotated upward, and the small torsion spring 301 is deformed immediately. When the sensor 1 moves upward to contact the ball 501, the sensor 1 squeezes the ball 501 and causes the paired ball 501 and the connecting tube 5 to move in opposite directions. The reset spring 502 is then compressed, and when the sensor 1 moves upward until the ball 501 enters the groove of the sensor 1, the paired ball 501 and the connecting tube 5 move toward each other under the reset action of the reset spring 502, and clamp the sensor 1. At this time, the sensor 1 completely enters the main box 2 and is separated from the square rotating plate 3. The paired square rotating plates 3 are rotated downward to return to their original positions under the reset action of the small torsion spring 301, and then the large round head plate 13 is released. The large round head plate 13 and the rounded corner column 12 rotate counterclockwise to return to their original positions under the reset action of the vertical torsion spring 14 and resist the paired square rotating plates 3. Then the round head plate frame 15 is inserted back into the large round head plate 13 and the main box 2 to prevent the large round head plate 13 from rotating.
[0028] When the photoelectric sensor needs to dissipate heat for efficient operation, people can start the motor 9 to drive the circular rotating plate 8 to rotate 90 degrees clockwise, and then start the fan 7 to suck out the hot air in the protective shell 4. At the same time, the external air also enters the connecting long tube 11 through the heat conducting tube 10, and then enters the protective shell 4 through the connecting long tube 11 to achieve air circulation, so as to cool down the sensor 1. When cooling is not needed, start the motor 9 again to drive the circular rotating plate 8 to rotate 90 degrees counterclockwise to return to its original position, and then turn off the fan 7.
[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
