[0006] It also includes a fixture which is coaxially arranged with the dust cover in the vertical direction, and a vertical line which passes through the dust cover to the bottom of the stainless steel tray is fixedly arranged on the fixture.

[0007] Preferably, the dust cover is a conical structure, and the narrow opening is arranged close to the fixture.

[0008] Preferably, the stainless steel tray is composed of a trapezoidal support leg and a rectangle, and the rectangle is arranged at the lower bottom of the trapezoidal support leg.

[0009] Preferably, a hanging member is provided at the upper bottom of the trapezoidal support leg, and an oil drum is provided on the hanging member.

[0010] Preferably, a heavy hammer is arranged in the rectangle, opposite to the oil barrel and located on the same axis.

[0011] Preferably, a notch is provided on one side of the rectangle relative to the trapezoidal support leg, and vertical folds are provided on ports on both sides of the notch, and one end of the vertical fold is connected to the dust cover.

[0012] In the above technical scheme, the utility model provides a dust-proof device for a vertical line in a dam corridor, which has the following beneficial effects: the vertically coaxially arranged fixer and dust cover can guide the rust residue in the upper pipe to the stainless steel tray by the dust cover, thereby avoiding dust attachment to the vertical line.

[0016] 1. Stainless steel tray; 2. Dust cover; 3. Fixer; 4. Plumb line; 5. Hanging piece; 51. Oil drum; 6. Heavy hammer; 7. Vertical pleats. DETAILED DESCRIPTION

[0017] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0018] like Figure 1 As shown, a vertical dust prevention device for a dam gallery includes a stainless steel tray 1 fixed to a wall by an angle iron, and a dust cover 2 is arranged inside the stainless steel tray 1;

[0019] The device further comprises a fixture 3 which is arranged coaxially with the dust cover 2 in the vertical direction, and a vertical line 4 which passes through the dust cover 2 and extends to the bottom of the stainless steel tray 1 is fixedly arranged on the fixture 3 .

[0020] Specifically, in the above embodiment, the dust cover 2 is a conical structure, and the narrow opening is arranged close to the holder 3. And the wide opening radius of the dust cover 2 is greater than the radius of the holder 3.

[0021] In this embodiment, the fixture 3 and the dust cover 2 arranged vertically and coaxially can guide the rust residue in the upper pipeline to the stainless steel tray 1 through the dust cover 2, thereby preventing the vertical line 4 from being attached with dust.

[0022] As an embodiment further provided by the present invention, the stainless steel tray 1 is composed of a trapezoidal support leg and a rectangle, and the rectangle is arranged at the bottom of the trapezoidal support leg.

[0023] Secondly, a hanging member 5 is provided at the upper bottom of the trapezoidal support leg, and an oil drum 51 is provided on the hanging member 5. A heavy hammer 6 is provided in the rectangle and arranged opposite to the oil drum 51 and located on the same axis, so that the stainless steel tray 1 has a certain ability to withstand wind resistance.

[0024] As an embodiment further provided by the present invention, a notch is provided on one side of the rectangular relative to the trapezoidal support leg, and vertical pleats 7 are provided on the ports on both sides of the notch, and one end of the vertical pleats 7 is connected to the dust cover 2, which is used to guide the air outlet into the stainless steel tray 1 and blow away the sediment on the dust cover 2.

[0025] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
