[0034] Embodiment 1

[0035] like Figure 1-3 As shown, the present invention provides a dust collector for use in a special-shaped curved cabin of a precision instrument, comprising a water tank 1, a fan 2, a dust suction nozzle mechanism 4 and a guide mechanism 5;

[0036] The water in the water tank 1 performs water filtration on the dust-containing gas. When the dust-containing gas enters the water tank 1, the gas changes its moving direction in the water, while the dust particles continue to move in the original direction due to inertia and adhere to the water and stay in the water, thereby allowing the water tank 1 to complete the filtration of the dust-containing gas.

[0037] The air inlet of the fan 2 is connected to the telescopic pipe 3, and the air outlet of the fan 2 is connected to the dust outlet pipe 6. The end of the dust outlet pipe 6 away from the fan 2 is located in the water tank 1. The fan 2 is used to draw the dust-containing gas in the cabin to the water tank 1. When the fan 2 is running, the dust-containing gas in the cabin is transported to the dust outlet pipe 6 through the telescopic pipe 3, and then transported to below the water surface in the water tank 1 through the dust outlet pipe 6;

[0038] The dust suction nozzle mechanism 4 is installed at one end of the telescopic tube 3 away from the fan 2. The dust suction nozzle mechanism 4 includes a bracket assembly 7 and a rotating assembly 8. The rotating assembly 8 is used to drive the bracket assembly 7 to make a circular motion along the outer edge of one end of the telescopic tube 3.

Two limit blocks 12 are installed on the rotating rod 10, and the two limit blocks 12 are respectively located on both sides of the sleeve 11. The two limit blocks 12 limit the rotating rod 10, thereby ensuring that the rotating rod 10 and the sleeve 11 are located inside. A counterweight block 13 is provided at one end of the rotating rod 10. The counterweight block 13 is used to drive the rotating rod 10 to move in the direction of gravity. The rotating rod 10 is connected with a mounting frame 9. The frame 9 is used to install a cleaning mechanism 14, which is used to clean the dust on the inner wall of the cabin. The rotating assembly 8 drives the sleeve 11 to rotate and make a circular motion around the telescopic tube 3. During the rotation of the sleeve 11, under the action of the counterweight 13, the rotating rod 10 always moves in the direction of gravity in the setting direction of the sleeve 11. The rotating rod 10 drives the mounting frame 9 to reciprocate in the setting direction of the sleeve 11, and then drives the cleaning mechanism 14 to reciprocate in the setting direction of the sleeve 11, thereby increasing the contact area between the cleaning mechanism 14 and the cabin. The cleaning mechanism 14 lifts the dust in the cabin with a special-shaped curved surface, and the lifted dust particles are transported from one end of the telescopic tube 3 located in the cabin to the water tank 1, which solves the problem that the dust suction port of the existing dust collector is mostly suitable for flat surfaces and the dust on the curved surface is not sufficiently cleaned;

[0039] The guide mechanism 5 is installed on one side of the dust nozzle mechanism 4, and the guide mechanism 5 is used to understand the structure of the cabin and drive the telescopic tube 3 to extend into the cabin.

The side of the gear 16 away from the rotating guide rail 18 is connected to the output shaft of the motor 17. The side of the motor 17 away from the output shaft is connected to the sleeve 11. Under the joint action of the motor 17 and the rotating guide rail 18, the gear 16 rotates in the rotating guide rail 18 along the setting direction of the rotating guide rail 18. The gear 16 drives the motor 17 to make a circular motion along the setting direction of the rotating guide rail 18, and the motor 17 rotates with the output shaft of the motor 17 as the central axis, thereby driving the sleeve 11 to rotate. The motor 17 is powered by a busbar, and the output shaft of the motor 17, the gear 16 and the rotating ring 15 are all made of conductive materials.

[0043] In this embodiment, the guide mechanism 5 includes a guide seat 19, an endoscope 20 and a walking wheel 21. The guide seat 19 is installed on one side of the rotating ring 15 through a first connecting rod 22. The length of the first connecting rod 22 is greater than the length of the rotating rod, thereby ensuring that the guide seat 19 and the bracket assembly 7 cannot contact each other. An endoscope 20 is installed on the guide seat 19, and the endoscope 20 is used to explore the environmental conditions in the cabin. A walking wheel 21 is installed on the side of the guide seat 19 close to the cabin.

The hardness of the first bristles 30 is less than that of the second bristles 31. When the hardness of the precision instrument is relatively large, the second bristles 31 are selected for dust removal, thereby ensuring the dust removal efficiency. When the hardness of the precision instrument is relatively small, the first bristles 30 are selected for dust removal, thereby ensuring that the precision instrument is not damaged. By setting a cleaning mechanism 14 with selectable bristle hardness, the damage of the dust collector to the precision instrument during the dust removal process is reduced, and the problem that the precision instrument is easily damaged during the dust removal process is solved.

[0045] In this embodiment, when the brush plate 28 is located close to the side of the mounting plate 27 connected to the first bristles 30, the length of the second bristles 31 on the side of the mounting plate 27 is greater than the length of the first bristles 30, and at this time, the second bristles 31 are in contact with the special-shaped curved surface of the cabin; when the brush plate 28 is located away from the side of the mounting plate 27 connected to the first bristles 30, the length of the second bristles 31 on the side of the mounting plate 27 is less than the length of the first bristles 30, and at this time, the first bristles 30 are in contact with the special-shaped curved surface of the cabin;

The sliding hook 34 is connected to the switching button 33, and the sliding hook 34 is inserted into the cavity in the mounting plate 27. The brush plate 28 is provided with a pressing guide rail 36, and the pressing guide rail 36 is provided with a first position 40 and a second position 41, the first position 40 is set away from the switching button 33, the second position 41 is set close to the switching button 33, the sliding hook 34 has a hook head 37, the hook head 37 is slidably set in the pressing guide rail 36, the hook head 37 is used to limit the brush plate 28, and then control the position of the brush plate 28 in the mounting plate 27, when the hook head 37 is located at the second position 41 on the pressing guide rail 36, the brush plate 28 is close to the first bristles 30, when the hook head 37 is located at the first position 40 on the pressing guide rail 36, the brush plate 28 is set away from the first bristles 30;

The guide seat 19 pulls the rotating ring 15 through the first connecting rod 22 to move in the cabin of the precision instrument to the area to be dusted. The guide seat 19 controls the second connecting rod 23 to rotate until the suction cup 24 is adsorbed on the inner wall of the cabin.
