[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-4 As shown, a dust removal device for a three-dimensional scanning galvanometer includes a three-dimensional scanning galvanometer body 1 and a lens 16. The lens 16 is disposed on one side of the three-dimensional scanning galvanometer body 1. Two sets of air outlet pipes 3 are disposed on one side of the three-dimensional scanning galvanometer body 1. The two sets of air outlet pipes 3 are symmetrically distributed about the central axis of the lens 16. Several air outlet heads 10 are connected to one side of each set of air outlet pipes 3. A first connecting pipe 4 is fixedly connected to the other side of each set of air outlet pipes 3. A diversion pipe 5 is fixedly connected to one side of the three-dimensional scanning galvanometer body 1. Two sets of connection ports are opened on one side of the diversion pipe 5. The two sets of connection ports are symmetrically distributed.

[0023] In this embodiment, the other ends of the two sets of first connecting pipes 4 are connected to the connection port, the other end of the diversion pipe 5 is fixedly connected to the second connecting pipe 8, a blower 7 is provided on one side of the three-dimensional scanning galvanometer body 1, the output end of the blower 7 is connected to the air supply pipe 6, the other end of the air supply pipe 6 is fixedly connected to one end of the second connecting pipe 8, and several air outlets 10 are inclined, with the air outlet of the air outlet 10 obliquely facing the lens 16.

[0024] When the device is used outdoors, the blower 7 is activated to generate airflow. The blower 7 delivers air to the splitter pipe 5 on the top of the 3D scanning galvanometer body 1 through the air supply pipe 6 and the second connecting pipe 8. The air in the splitter pipe 5 enters the two sets of first connecting pipes 4 through the connection port. Thus, the air generated by the blower 7 enters the air outlet pipe 3 and is blown towards the lens 16 by the air outlet head 10. Since the air outlet of the air outlet head 10 is angled towards the lens 16, it is easy for the air to blow onto the lens 16, blowing away the dust on the lens 16. This prevents dust in the surrounding air from adhering to the lens and contaminating the lens on which the galvanometer is placed, ensuring that the light output effect is not affected, thereby ensuring the accuracy of the monitoring data and facilitating monitoring by the staff.

[0025] In this embodiment, a dust cover 2 is fixedly connected to one side of the three-dimensional scanning galvanometer body 1. The dust cover 2 has several slots 9, which are evenly distributed in an array. Several air outlets 10 pass through the slots 9 at one end.

[0026] The dust cover 2 further blocks the dust around the mirror 16, and the dust cover 2 connects the air outlet pipe 3 and the three-dimensional scanning galvanometer body 1 together, and the air outlet head 10 on the air outlet pipe 3 passes through the slot 9 on the dust cover 2, so that the air is blown to the mirror 16.

[0027] In the embodiment, two groups of positioning grooves 11 are arranged on one side of the air outlet pipe 3, and the two groups of positioning grooves 11 are symmetrically distributed about the central axis of the air outlet pipe 3.

[0028] When the air outlet pipe 3 needs to be connected with the three-dimensional scanning galvanometer body 1, the positioning grooves 11 on the air outlet pipe 3 are first aligned with the positioning rods 12 and inserted, so that the air outlet head 10 on the air outlet pipe 3 is inserted into the slot 9, and the air outlet head 10 is conveniently and quickly inserted into the slot 9.

[0029] In the embodiment, a fixing groove 14 is arranged on one side of the positioning rod 12, a fixing plate 13 is clamped in the fixing groove 14, a bolt 15 is rotatably connected to the positioning rod 12, a threaded groove is arranged on the fixing plate 13, and one end of the bolt 15 is screwed into the threaded groove.

[0030] After the air outlet pipe 3 is fixed on the positioning rod 12, the fixing plate 13 is placed in the fixing groove 14, and the bolt 15 is screwed into the threaded groove, so that the fixing plate 13 is fixed in the fixing groove 14, the position of the air outlet pipe 3 is limited, the air outlet pipe 3 is prevented from falling off the positioning rod 12, and the connection reliability of the air outlet pipe 3 and the three-dimensional scanning galvanometer body 1 is improved.

[0031] It should be noted that the dust removal device for the three-dimensional scanning galvanometer is used when the equipment is used outdoors, and the air blower 7 generates air power at the same time. The air blower 7 sends the air into the shunt pipe 5 at the top of the three-dimensional scanning galvanometer body 1 through the air conveying pipe 6 and the second connecting pipe 8, the air in the shunt pipe 5 enters the two groups of first connecting pipes 4 through the connecting ports at the same time, so that the air generated by the air blower 7 enters the air outlet pipe 3 and blows to the mirror 16 through the air outlet head 10. Since the air outlet of the air outlet head 10 is inclined to the mirror 16, the air is blown to the mirror 16, the dust on the mirror 16 is blown away, the dust in the air around the mirror is prevented from adhering to the mirror, and the dust cover 2 arranged on the three-dimensional scanning galvanometer body 1 further blocks the dust around the mirror 16, and the dust cover 2 connects the air outlet pipe 3 and the three-dimensional scanning galvanometer body 1 together.
