Problems solved by technology

Because there is a lot of dust in the underground environment of coal mines, the existing screens are easily polluted and difficult to clean; and because the roadway needs to maintain good ventilation to dilute the concentration of mine gas, the screens will be blown by the wind, affecting normal display and even It will tear the curtain, and if the curtain structure is fixed, it will bring difficulties in handling and maintenance

Embodiment Construction

[0019] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings; it should be noted that the embodiments are illustrative, not restrictive, and cannot limit the protection scope of the present invention.

[0020] A non-cleaning display screen for a mine projector includes a display cloth base 4, which is a cloth base woven from textile threads. A layer of tiny glass beads 3 , a transparent film layer 2 and a nanomaterial coating 1 are sequentially compounded on the upper surface of the display cloth base from bottom to top. The tiny glass bead layer is composed of uniform and fine glass powder coated on the surface of the display cloth, and the glass powder is a fine quartz crystal. The micro glass bead layer and the display cloth base, and the transparent film layer and the micro glass bead layer are bonded by photosensitive adhesive, and then cured and compounded by ultraviolet light irradiation. The nano mater...

Abstract

The invention relates to a mine projector no-clean display curtain and an installation method thereof. The display curtain comprises a display curtain base, the upper surface of the display curtain base is sequentially provided with a composite tiny glass bead layer, a transparent film layer and a nanometer material coating from bottom to the top, and the display curtain is transversely arranged conforming to the wind direction of a mine. The mine projector no-clean display curtain is scientific in design, reasonable in structure and convenient to use, the surface of the display curtain is processed through nanometer material and is not prone to adsorbing dust, the problems that a large amount of coal dust in a roadway of the mine is accumulated to pollute the curtain and the curtain is cleaned difficultly are solved, and the mine projector no-clean display curtain saves energy, is environmentally friendly, saves time and labor, and is economical and practical. In addition, after the installation method is adopted, pictures projected by the curtain are high in definition, the visual angle is large, and influence of wind blowing is avoided.

Description

technical field [0001] The invention relates to the field of mine projectors, in particular to a no-cleaning display screen for a mine projector and an installation method thereof. Background technique [0002] In the tunnels of coal mines, projectors are often used to display and play some information and animations. The traditional projector screens currently used are mainly divided into white plastic screens, glass bead screens, and metal screens. Due to the large amount of dust in the underground environment of coal mines, the existing screens are easily polluted and difficult to clean; and due to the need to maintain good ventilation in the roadway to dilute the concentration of mine gas, the screens will be blown by the wind, affecting normal display and even It will tear the curtain, and if the curtain structure is fixed, it will cause difficulties in handling and maintenance. Contents of the invention [0003] The object of the present invention is to provide a n...
