As shown in FIG. 2, the protective glass connection panel 10, the air spray nozzle 20, the solenoid valve 30, the air supply pipe 40, the portable air conditioner 50, and the air suction hole 60 are illustrated. ), The air discharge pipe 70, the suction pump 80, the moisture control module 90, and a wireless remote control unit 100.

First, the glass connection panel part 10 for protection which concerns on this invention is demonstrated.

The protective glass connection panel 10 is detachably connected to the end of the objective lens in an annular band shape, and serves to form an air film on the surface of the protective glass by spraying and blowing dry air on the surface of the protective glass while being zoomed in or zoomed out like the objective lens. .

It is made of an annular band shape, and is made of a plastic alloy material that is light, elastic, durable, and moisture absorbing.

The protective glass connection panel 10 is a lightweight elasticity and durability is improved by using a polyamide resin having a strong hygroscopicity,

The protective glass connection panel 10 is pre-heated 0.7 equivalent dimer acid to 100 ℃ in the reactor to completely remove the residual bubbles, and then added 0.3 equivalent Sebacic acid, 0.5 equivalent Ethylenediamine, 0.5 equivalent Piperazine to the reactor in order The reaction by-product removes H ₂ O and adds 1 ~ 2 wt% of tetraethoxysilane to the total weight of the reactor to induce a sol-gel reaction of the alcoxy-silane precursor. Proceeds to the end of the reaction if there is no change in the 80 ~ 90wt% polyamide resin synthesized by terminating the reaction,

5-15 wt% of glass fibers having a tensile strength (MPa) of 18.4 to 35.7, modulus of elasticity (MPa) of 7.1 × 10 ² to 7.8 × 10 ² , elongation (%) of 2.0 to 3.0, and density (g / cm 3) of 2.27,

It is manufactured by extrusion molding.

The polyamide (polyamide) is a generic name for the linear polymer containing an amide group (-NH-CO) in the molecular structure is a representative crystalline synthetic resin. There are three general methods for synthesizing polyamides: by ring-opening polymerization of lactam, by polycondensation of aminocarboxylic acids, and by polycondensation of diamine and dibasic acids.

Since the amide group has hydrophilicity, the polyamide has hygroscopicity, and the amount of absorption increases as the lower the (-CH ₂ ) / (-NH-CO) ratio in the molecule and the lower the crystallinity. However, moisture in the polyamide can act as a plasticizer and can lower the strength and rigidity of the resin.

The polyamide resin is used to increase the tensile strength by using tetraethoxysilane in order to improve the durability in addition to the basic properties of light, stretchy and hygroscopic high.

When the amount of the polyamide resin is less than 80wt%, the moldability is inferior, and when the amount of the polyamide resin is more than 90wt%, the durability may be deteriorated. Therefore, the amount of the polyamide resin is limited to 80 to 90wt% of the total mixture. It is desirable to. More specifically, it is preferable to use 85wt%.

The glass fiber has a tensile strength (MPa) of 18.4 to 35.7, modulus of elasticity (MPa) of 7.1 × 10 ² to 7.8 × 10 ² , elongation (%) of 2.0 to 3.0, and density (g / cm 3) of 2.27, the amount of which is 5wt If it is less than%, the durability may be lowered, and if it exceeds 15 wt%, moldability may be lowered. Therefore, the amount of the glass fiber used is preferably limited within the range of 5 to 15 wt% with respect to the entire mixture. More specifically, it is more preferable to use 13wt%.

The surfactants include diacetyl monoglycerides, diethylene glycol monopalmitostearate, ethylene glycol monopalmitostearate, glyceryl behenate, glyceryl distearate, glyceryl monolinoleate, polyoxyethylene monooleate, When one or two or more selected from polyoxyethylene sorbitan monolaurate and polyoxyethylene sorbitan monostearate, when the amount is less than 0.1wt%, dispersibility is inferior, and when it exceeds 5wt% Since there is no big change in dispersibility and is meaningless, it is preferable to limit the usage-amount of the said surfactant within the range of 0.1-5 weight% with respect to the whole mixture. More specifically, it is more preferable to use 2wt%.

Here, the reason for forming the size of 0.4 times to 0.7 times the diameter of the protective glass is 0.4 times or less, there is a risk that the band-shaped rubber packing member is in close contact with the protective glass and torn, and at 0.7 times or more the close contact with the protective glass There is a risk that the bag will be loose and the rubber-packed connection panel will fall out of the protective glass.

As shown in FIG. 14, the elastic support type connection panel 12 includes an elastic support member 12b formed at an inner side of the connection panel main body 12a connected to the protective glass tip to include the protective glass therein. While attaching and detaching.

The air spray nozzle 20 is configured to be inclined at 15 ° to 60 ° in a tip direction with respect to the vertical reference line inside the upper portion of the protective glass connection panel to inject the high pressure spray in a diagonal direction to the protective glass surface.

This is formed when the protective glass connection panel is viewed from the side, the air spray nozzle formed inside the top is inclined at 15 ° ~ 60 ° in the tip direction with respect to the vertical reference line.

Here, the reason why the air spray nozzle is inclined at 15 ° to 60 ° in the tip direction with respect to the vertical reference line is that under 15 °, the high-pressure dry air through the air spray nozzle is not sprayed along the protective glass surface, and the protective glass As it passes directly along the upper part of the glass, it is difficult to remove foreign substances from the surface of the protective glass.At 60 ° or more, the high-pressure drying air through the air spray nozzle is sprayed directly onto the protective glass surface to vibrate on the protective glass.
