[0032] It also includes a dust removal device, which is provided with an air pump; the air pipe 3 of the air pump is connected to a jet head, and the jet end of the jet head faces the dust-proof glass 2; it also includes an electric reciprocating lifting system, the lifting action mechanism of the electric reciprocating lifting system adopts a screw 8 mechanism, and the jet head is arranged on a slider 4 of the screw 8 mechanism; it also includes an infrared beam switch, and the sensor of the infrared beam switch includes an infrared beam sensor; the control signal output end of the infrared beam switch controls the connection of the air pump and the electric reciprocating lifting system; the infrared emitting element and the infrared receiving element of the infrared beam sensor are respectively located on both sides of the dust-proof glass 2, forming a beam arrangement structure ; By setting up a dust removal device, the dust on the dust-proof glass 2 can be removed through a jet head connected to an air pump, and there is no need to manually climb up to a high place to clean the lens, which saves manpower. Secondly, an electric reciprocating lifting system is used to allow the jet head to circulate and clean the dust-proof glass 2, so that the jet head can clean the entire dust-proof glass 2, thereby increasing the cleaning effect of the dust removal device; finally, by setting up an infrared counter-beam switch, the infrared counter-beam sensor can be used to monitor whether there is dust on the dust-proof glass 2, and the air pump and the electric reciprocating lifting system can be automatically turned on, making the dust removal device more convenient and quick to use. The model of the infrared counter-beam sensor is ML100, and the model of the infrared counter-beam switch is TCRT5000.

[0033] The screw 8 mechanism also includes a motor 7 and a screw 8 connected to the motor 7. The motor 7 is fixedly arranged on the side of the shell 1, and the motor 7 drives the screw 8 to rotate, and the screw 8 rotates in coordination with the shell 1; the control signal output end of the infrared beam switch also controls the motor 7; by setting the motor 7 to drive the screw 8 to rotate, the infrared beam switch controls the motor 7 to turn on, thereby realizing the control of the electric reciprocating lifting system by the infrared beam switch, and the motor 7 is a servo motor 7, which is provided with a controller with a cyclic reciprocating working program, and the controller model is S7-1500.

[0034] The nozzle head includes a conduit 5, the slider 4 is rotatably connected to the conduit 5, at least two nozzles 6 are arranged on the conduit 5, the conduit 5 is connected to the air pipe 3, and the nozzles 6 are further connected to the air pipe 3; the nozzles 6 face the dust-proof glass 2, and the angle between the gas ejected from the nozzles 6 and the dust-proof glass 2 is 25°-65°; by arranging the inclined nozzles 6, the air ejected from the nozzles 6 can better blow away the dust, and the dust removal effect is better.

[0035] A slide rod 9 is also provided on the housing 1, one end of the slider 4 cooperates with the slide rod 9, and the other end cooperates with the screw 8 threadedly; by providing the slide rod 9, the slider 4 can slide along the slide rod 9 when the screw 8 rotates, thereby achieving the purpose of the screw 8 driving the nozzle to circulate.

[0036] When in use, when the infrared counter-radiation sensor detects that dust has fallen on the dust-proof glass 2, the infrared counter-radiation sensor sends a signal to the infrared counter-radiation switch, and the infrared counter-radiation switch controls the start of the air pump and the motor 7. The air pump works to deliver high-pressure gas to the air nozzle 6 through the air pipe 3. The air nozzle 6 sprays and cleans the dust on the dust-proof glass 2. At the same time, the motor 7 starts to work to drive the screw 8 to rotate. The rotation of the screw 8 drives the slider 4 to slide along the slide bar 9.

[0037] Example 2

[0038] Reference Figure 2 to Figure 4 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0039] The conduit 5 is also provided with a protrusion 11 for driving the conduit 5 to rotate, and the outward extension direction of the protrusion 11 is consistent with the jet direction of the air nozzle 6. The housing 1 is provided with at least two columns 10 for driving the protrusion 11. After the protrusion 11 drives the conduit 5 to rotate, the air nozzle 6 is still facing the dust-proof glass 2. By providing the protrusion 11 and the column 10, when the air nozzle moves to the limit on one side, the protrusion 11 is pushed to the other side, so that the air nozzle 6 rotates the jet direction, and the air nozzle 6 continues to clean the dust from the other side at an angle of 25°-65°, so that the dust removal device has no dead angle for dust removal and the cleaning effect is better.

[0040] The slider 4 is provided with a spring buckle 12 which engages with the protrusion 11; at least two limit blocks for limiting the rotation angle of the conduit 5 are also provided on the side of the slider 4, and the limit blocks correspond to the positions of the protrusion 11; by providing the limit blocks, the air nozzle 6 is prevented from rotating to an angle where it cannot blow onto the dust-proof glass 2, so that the dust removal device can operate more stably.

[0042] A high-pressure limiting valve is connected to the air pipe 3; by setting the high-pressure limiting valve, the dust removal device limits the maximum gas pressure in the air pipe 3 when working, preventing the gas pressure ejected from the air nozzle 6 from being too high to damage the dust-proof glass 2.

[0043] During use, when the slider 4 makes a cyclic reciprocating motion, the air nozzle 6 passes through an inclination angle of 25°-65°, which makes it easier to clean the dust. When the slider 4 moves near the column 10, the column 10 will move the protrusion 11, and the protrusion 11 drives the conduit 5 to rotate. The protrusion 11 is provided with two slots that can cooperate with the spring buckle 12. The protrusion 11 rotates until the spring buckle 12 switches from one slot to another, thereby realizing the reversal of the air nozzle 6. When the slider 4 reverses its motion, the air nozzle 6 also turns its direction so that the air nozzle 6 can maintain an inclination angle of 25°-65° to clean the dust-proof glass 2, so that the dust removal device can clean without dead ends and the dust removal effect is better.
