Therefore, the utility model discloses the technical scheme who adopts does: the utility model provides an air curtain device for protection of field lens, installs the air cock of inserting soon on the air curtain subassembly including installing air curtain subassembly and the ring week in the field lens bottom, the air curtain subassembly includes air curtain safety cover main part and is located the air curtain protection shroud under the air curtain safety cover main part, air curtain safety cover main part ring week is equipped with air cock butt joint air vent and docks the hoop ventilation notch of air cock intercommunication with the air cock, air curtain protection shroud inner wall upper portion inclination and with air curtain safety cover main part down along the inclined plane form the hoop oblique seam of giving vent to anger, air curtain protection shroud inner wall lower part camber and with air curtain safety cover main part down along the inclined plane form triangle breach, insert the air cock soon and install on air cock butt joint air vent and can transport gas to hoop ventilation notch.
As the preferred of above-mentioned scheme, gas curtain protective cover lid passes through the fix with screw with gas curtain protective cover main part to be equipped with gas curtain protective cover sealing washer, the installation is firm, effectively ensures the leakproofness of junction, avoids the gas in the hoop ventilation notch to overflow along both junctions of gas curtain protective cover lid and gas curtain protective cover main part.
Further preferably, the air curtain protection cover main body is in threaded connection with the field lens and is provided with a sealing ring, the threaded connection is convenient to install and stable and firm, and friction at the joint is effectively reduced by the sealing ring.
Further preferably, the air outlet end external thread of the quick inserting air faucet is matched with the internal thread of the air faucet butt joint air vent, the quick inserting air faucet can be fixed on the air curtain protection cover main body through screwing, the operation is simple and convenient, and the sealing performance is good.
The utility model has the advantages that:
(1) gas curtain protection shroud inner wall upper portion inclination and with gas curtain protection shroud main part down along the inclined plane formation hoop to give vent to anger the oblique seam, gas curtain protection shroud inner wall lower part extroversion and with gas curtain protection shroud main part down along the inclined plane formation triangle breach, thereby make to give vent to anger oblique seam spun gas along the hoop and be fan-shaped, the spray regime is wider, the environmental cleaning is more high-efficient, the protection zone of scene bottom is bigger, when effectively guaranteeing to change the scene window screening glass, all ring edge borders are clean and do not have the dust, smog, impurity such as slag.
(2) Compared with the prior art, the air knife is adopted to blow air transversely at the field lens window position, the air curtain is formed at the field lens window position to protect the lens, the air pressure on the surface of the lens is uniform and stable, the position near the lens is in positive pressure constantly, and dust feeding is effectively avoided.
In conclusion, the method has the advantages of good protection effect of the field lens, clean and efficient scene environment and the like.

Fig. 1 is a front sectional view of the present invention.
Fig. 2 is a partially enlarged view of a portion a of fig. 1.
Detailed Description
The invention will be further described by way of examples with reference to the accompanying drawings:
referring to fig. 1-2, an air curtain device for protecting a lens of a field lens comprises an air curtain component 2 installed at the bottom of the field lens 1 and a quick insertion air nozzle 3 installed on the air curtain component 2 circumferentially.
The air curtain assembly 2 is composed of an air curtain shield main body 21 and an air curtain shield cover 22 located right below the air curtain shield main body 21.
The air curtain protection cover main body 21 is screwed with the field lens 1 and is provided with a sealing ring.
The air curtain shield cover 22 is fixed to the air curtain shield cover main body 21 by screws, and is provided with an air curtain shield packing 213.
