Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

When the mine car is traveling, dust will be raised. The raised dust can be shielded by the annular lens 6 to prevent the dust from adhering to the camera 5. The first motor 30 can be started to rotate its output shaft to drive the carrier plate 2 to rotate, thereby driving the side plate 3 and the spherical block 4 to rotate, and then driving the camera 5 to rotate, so that the angle of the camera 5 can be adjusted. The second motor 7 can be started to rotate its output shaft to drive the rubber tube 8 to rotate, thereby driving the annular lens 6 to rotate through friction, so that the annular lens 6 continuously passes through the cleaning liquid in the box body 9, so that the dust and impurities on the annular lens 6 are cleaned by the cleaning liquid, so that the dust and impurities leave the annular lens 6, and the cleaning is achieved. The cleaned annular lens 6 can be dried by the drying component to complete the cleaning of the annular lens 6. The cleaning of the annular lens 6 can be completed without affecting the use of the camera 5, so that the annular lens 6 can be kept in a clean state, thereby ensuring the clarity of the camera 5. When used in a dusty environment, the camera 5 can ensure clear shooting. When the annular lens 6 just enters the cleaning liquid, the dust and impurities on its surface will be washed away by the cleaning liquid and remain on the surface of the cleaning liquid. At this time, the impurity removal component can be used to remove the dust and impurities washed down in the cleaning liquid, so that when the annular lens 6 leaves the cleaning liquid, there will be no impurities attached to its surface, so that the cleaning effect is better.

[0030] like Figure 2As shown, the impurity removal component includes a cylinder body 12 fixedly mounted on the outside of the box body 9, a piston is arranged inside the cylinder body 12, and a driving component is arranged outside the piston for cooperating with the rubber tube 8 to drive the piston to reciprocate up and down.

The lower outer side of the cylinder 12 is connected to the adjacent transverse pipe 11 through the extraction pipe 13. The bottom of the cylinder 12 is connected to a filter assembly through an injection pipe 14. The side of the filter assembly away from the injection pipe 14 is connected to the transverse pipe 11 on the other side through a return pipe 15. The rubber cylinder 8 rotates and cooperates with the driving assembly to drive the piston to reciprocate up and down. When the piston descends, the cleaning liquid with dust and impurities in the cylinder 12 is squeezed out. At this time, the one-way valve in the tube body 10 close to the cylinder 12 is closed, and the one-way valve in the tube body 10 away from the cylinder 12 is opened, with The cleaning liquid with dust and impurities moves into the box body 9 through the injection pipe 14, the filter assembly, the reflux pipe 15, the cross pipe 11 and the tube body 10. When the cleaning liquid passes through the filter assembly, the dust and impurities inside are removed and filtered, so that the filtered cleaning liquid returns to the box body 9. When the piston rises, the cleaning liquid is drawn into the cylinder body 12. At this time, the one-way valve in the tube body 10 close to the cylinder body 12 is opened, and the one-way valve in the tube body 10 away from the cylinder body 12 is closed. The cleaning liquid with dust and impurities after cleaning the annular lens 6 is passed through the tube body 10, The horizontal tube 11 and the extraction tube 13 are drawn into the cylinder body 12, so that the cleaning liquid containing dust and impurities can be extracted. Through the reciprocating motion of the piston, the cleaning liquid containing dust and impurities generated by cleaning the annular lens 6 can be continuously extracted, and then discharged into the box body 9 after purification, so that the cleaning liquid can maintain a clean state, and dust and impurities will not be suspended on the surface of the cleaning liquid, so as to avoid the situation that the annular lens 6 is stuck with suspended dust and impurities when leaving the cleaning liquid after entering the cleaning liquid for cleaning, thereby improving the cleaning effect.

[0031] like Figure 3As shown, the filter assembly includes a box body 16 fixedly mounted on the top of the carrier plate 2, and the two sides of the box body 16 are respectively connected to the injection pipe 14 and the return pipe 15. A cover 17 is provided on the top of the box body 16, and a first filter screen 18 is symmetrically provided below the cover 17. The first filter screen 18 is fitted with the injection pipe 14 and the return pipe 15, and activated carbon is filled between the two first filter screens 18. The cover 17 is made of magnets, and the box body 16 is made of iron, so that the cover 17 is easy to be adsorbed and fixed to the box body 16. The cover 17 can be removed, and then the first filter screen 18 can be removed. Take it out for cleaning, and replace the activated carbon at the same time. Then the first filter 18 can be reset, and the activated carbon can be placed between a pair of first filters 18. The cover 17 and the box body 16 are adsorbed and fixed. The cleaning liquid with dust and impurities enters the box body 16 through the injection pipe 14, and will first be filtered by the first filter 18 to filter the dust and impurities. Then the cleaning liquid passes through the activated carbon to absorb the fine impurities inside, and then enters the reflux pipe 15 after being filtered by the first filter 18, thereby achieving the filtration and purification of the cleaning liquid with dust and impurities.

[0032] like Figure 2 and Figure 4 As shown, the driving assembly includes a pressure rod 19 fixedly connected to the top of the piston, the top of the pressure rod 19 extends to the outside of the cylinder body 12 and is fixedly connected to a pressure plate 20, a spring is sleeved on the outside of the pressure rod 19 and located between the pressure plate 20 and the cylinder body 12, and an extrusion assembly is provided above the pressure plate 20 for cooperating with the rubber tube 8 to squeeze the pressure plate 20 to make it descend. The rubber tube 8 rotates to cooperate with the extrusion assembly to squeeze the pressure plate 20 downward, thereby driving the pressure rod 19 and the piston to descend, and at the same time compressing the spring to deform it to generate a force. When the extrusion assembly cancels the extrusion of the pressure plate 20, the spring releases the force to drive the pressure plate 20, the pressure rod 19 and the piston to rise and reset.

[0033] like Figure 4 As shown, the extrusion assembly includes a cross bar 23 fixedly connected to the middle part of the end of the rubber tube 8 away from the second motor 7, the end of the cross bar 23 away from the rubber tube 8 extends to the outside of the spherical block 4, and a connecting plate is fixedly installed on the outside of the side plate 3 near the cross bar 23, and a rotating rod 21 is rotatably installed on the inner side of the connecting plate. The outside of the rotating rod 21 and the end of the cross bar 23 located outside the spherical block 4 are fixedly installed with pulleys, and the two pulleys are connected by a belt 24. A cam 22 is fixedly installed on the end of the rotating rod 21 close to the pressure plate 20, and the cam 22 is always in contact with the pressure plate 20. The rotation of the rubber tube 8 drives the cross bar 23 to rotate, thereby driving the rotating rod 21 and the cam 22 to rotate through the pulley and the belt 24, so that the cam 22 continuously squeezes and cancels the pressure plate 20.

[0034] like Figure 2 and Figure 5As shown, the drying component includes a square tube 25, a drying port is provided on the outside of the spherical block 4 and between the return pipe 15 and the camera 5, the square tube 25 is fixedly installed in the drying port, an air pump 26 is fixedly installed at the bottom of the square tube 25, the exhaust end of the air pump 26 is connected to the square tube 25, channels connected to the placement groove are provided on both sides of the spherical block 4, the air suction end of the air pump 26 is connected to the adjacent channel through a hose 27, and a second filter screen 28 is provided at the end of the channel away from the hose 27. There is a gap between the annular lens 6 and the annular cavity. The air suction pump 26 is started to exhaust air at its exhaust end, so that the external air is discharged. After the air is filtered by the second filter 28, it is extracted through the channel, the placement groove, and the hose 27, and then injected into the square tube 25 through the exhaust end. When the outside air passes through the placement groove, it can take away the heat generated by the camera 5 when it is working, so that the camera 5 can be cooled, so that the air injected into the square tube 25 has heat, and then the hot air is blown to the annular lens 6 to air-dry it, so that the cleaning liquid on its surface is dried. The vacuum pump 26 continuously works, so that the heat generated by the camera 5 can be continuously taken away, and this part of the heat is used to air-dry the annular lens 6, thereby improving the air-drying rate.

[0035] like Figure 2 As shown, the support assembly includes a plurality of cylinders 29, arc grooves are provided on the top and bottom of the spherical block 4, and the plurality of cylinders 29 are equidistantly rotatably installed in the arc grooves. The cylinders 29 are in contact with the inner wall of the annular lens 6, and the annular lens 6 is supported by the rotating cylinders 29, so that the annular lens 6 can rotate in the annular cavity.

[0036] like Figure 1 As shown, the box body 9 is configured as a box-shaped component made of glass, so that the remaining amount of the cleaning liquid in the box body 9 can be easily observed and replenished in time.

[0037] Working principle: when in use, the base 1 can be fixed on the mine car. When the mine car is driving, dust will be raised. The raised dust can be shielded by the annular lens 6 to prevent the dust from adhering to the camera 5. The first motor 30 can be started to rotate its output shaft to drive the carrier plate 2 to rotate, thereby driving the side plate 3 and the spherical block 4 to rotate, and then driving the camera 5 to rotate, so that the angle of the camera 5 can be adjusted. The second motor 7 can be started to rotate its output shaft to drive the rubber tube 8 to rotate, thereby driving the annular lens 6 to rotate through friction, so that the annular lens 6 continuously passes through the cleaning liquid in the box body 9, so that the dust and impurities on the annular lens 6 are cleaned by the cleaning liquid, so that the dust and impurities leave the annular lens 6 to clean it, and the vacuum pump 2 is started 6 makes its suction end to evacuate air, so that the outside air is filtered through the second filter screen 28, and then extracted through the channel, the placement groove, and the hose 27, and then injected into the square tube 25 through the exhaust end. When the outside air passes through the placement groove, it can take away the heat generated by the camera 5 when it is working, so that the camera 5 can be cooled, so that the air injected into the square tube 25 has heat, and then the hot air is blown to the annular lens 6 to air dry it, so that the cleaning liquid on its surface is dried. The suction pump 26 continuously works, so that the heat generated by the camera 5 can be continuously taken away, and this part of the heat is used to air dry the annular lens 6, and the air drying rate is increased, so that the cleaning of the annular lens 6 is completed, so that the use of the camera 5 can be affected Under this condition, the cleaning of the annular lens 6 can be completed, so that the annular lens 6 can be kept in a clean state, thereby ensuring the clarity of the camera 5. When used in an environment with dust, the camera 5 can ensure clear shooting. When the annular lens 6 just enters the cleaning liquid, the dust and impurities on its surface will be washed away by the cleaning liquid and remain on the surface of the cleaning liquid. The rubber tube 8 rotates to drive the cross bar 23 to rotate, thereby driving the rotating rod 21 and the cam 22 to rotate through the pulley and the belt 24, so that the cam 22 continuously squeezes and cancels the squeezing of the pressure plate 20. When the pressure plate 20 is squeezed, the pressure rod 19 and the piston are driven to descend, and the spring is compressed to deform to generate a force. When the squeezing is canceled, the spring releases the force to drive the pressure plate 20. The plate 20, the pressure rod 19 and the piston rise and reset, so that the piston reciprocates up and down. When the piston descends, the cleaning liquid with dust and impurities in the cylinder 12 is squeezed outward. At this time, the one-way valve in the tube body 10 close to the cylinder 12 is closed, and the one-way valve in the tube body 10 away from the cylinder 12 is opened. The cleaning liquid with dust and impurities moves into the box body 9 through the injection pipe 14, the filter assembly, the reflux pipe 15, the cross pipe 11 and the tube body 10. When the cleaning liquid passes through the filter assembly, the dust and impurities inside are removed and filtered, so that the filtered cleaning liquid returns to the box body 9. When the piston rises, the cleaning liquid is drawn into the cylinder 12. At this time, the one-way valve in the tube body 10 close to the cylinder 12 is opened, and the one-way valve in the tube body 10 away from the cylinder 12 is closed.After cleaning the annular lens 6, the cleaning liquid with dust and impurities is drawn into the cylinder 12 through the tube 10, the horizontal tube 11, and the extraction tube 13, so that the cleaning liquid with dust and impurities can be extracted. Through the reciprocating motion of the piston, the cleaning liquid with dust and impurities generated by cleaning the annular lens 6 can be continuously extracted and discharged into the box body 9 after purification, so that the cleaning liquid can maintain a clean state, so that dust and impurities will not be suspended on the surface of the cleaning liquid, and the situation that the annular lens 6 is prevented from sticking to the suspended dust and impurities when leaving the cleaning liquid after entering the cleaning liquid for cleaning is completed, so that the cleaning effect can be improved.
