[0028] The frame 110 is used for installing the body 120 to maintain the stability of the body 120, and the lens 130 and the observation window 140 are respectively installed on the two sides of the body 120 to survey the target.

[0029] The protection mechanism 200 comprises a sleeve 210 threadedly connected to the outer side of the lens 130, a UV mirror 220 fixed on the inner wall of the sleeve 210, a pipe body 230 installed on the top end of the sleeve 210 and communicating with the inner cavity of the sleeve 210, a high-speed fan 240 installed on the inner wall of the pipe body 230, a hanger 250 symmetrically fixed on the bottom end of the sleeve 210, a cover plate 260 rotatably installed on the hanger 250, and a driving piece 270 installed on the bottom end of the sleeve 210.

[0030] The outer thread is arranged on the outer side of the lens 130, and the inner thread is arranged on the inner wall of the end of the sleeve 210, which are engaged with each other, facilitating the installation of the sleeve 210 on the lens 130 and facilitating the installation and removal of the sleeve 210. The UV mirror 220 is fixed on the inner wall of the sleeve 210, and cooperates with the sleeve 210 to form a closed environment outside the lens 130, which can avoid the attachment of wind sand and dust on the lens 130. At the same time, the UV mirror 220 filters out ultraviolet rays, so that the distant scenery is clearer.

[0031] The wind hole 211 with a rectangular cross section is arranged on the inner wall of the side of the sleeve 210, and the inner bottom wall of the pipe body 230 is arranged in a V-shaped slope, and the wind hole 211 is communicated with the inner cavity of the pipe body 230. Through the above arrangement, when the high-speed fan 240 is started, air is sent into the wind hole 211, and the high-speed air is blown out from one side of the UV mirror 220 through the wind hole 211, so that a wind wall is formed on one side of the UV mirror 220, and the wind sand and dust can be blown away when they approach the UV mirror 220, thereby avoiding the attachment of the wind sand and dust on the surface of the UV mirror 220.

[0032] In addition, the filter screen 231 is installed at the top end of the pipe body 230, which can filter the air entering the pipe body 230, and avoid the wind sand and dust entering the inner cavity of the pipe body 230.

[0033] The cover plate 260 is used to close the sleeve 210 when it is idle, so as to avoid the wind sand and dust from entering the inner cavity of the sleeve 210. The end of the cover plate 260 is rotatably installed on the relative hanging bracket 250, which is convenient for rotation. The worm gear 261 is arranged in the middle of the end of the cover plate 260. At the same time, the driving member 270 includes the bracket 271 fixed on the outer side of the sleeve 210, the motor 272 installed on the bracket 271, and the worm 273 fixed on the shaft of the motor 272. The worm 273 is engaged with the worm gear 261, so that when the motor 272 is started, the worm 273 is driven to rotate, the worm 273 drives the worm gear 261 to rotate, and then drives the cover plate 260 to rotate, realizing the automatic opening and closing of the cover plate 260.

[0034] In addition, the output end of the infrared sensor 150 is electrically connected with the input end of the motor 272 through a wire, and the two are cooperated with each other. When the person approaches the observation window 140 for observation, the driving member 270 is started to drive the cover plate 260 to open. When the infrared sensor 150 detects that the person leaves, the driving member 270 is started again to drive the cover plate 260 to close.

[0035] The working principle and use flow of the utility model: when personnel approaches the observation window 140 to observe, the infrared sensor 150 detects the approach of personnel, starts the motor 272, the motor 272 rotates to drive the worm 273 to rotate, the worm 273 rotates to drive the worm wheel 261 to rotate, the worm wheel 261 rotates to drive the cover plate 260 to rotate, so that the cover plate 260 is opened, at this time personnel can carry out surveying and mapping to the target through the observation window 140, when observing, the UV mirror 220 cooperates with the sleeve 210 to form a closed environment, avoids wind sand dust to adhere on the lens 130, simultaneously, the high-speed fan 240 starts, air is accelerated to send into the air hole 211, air is sent out from the air hole 211 at high speed, forms a wind wall on the side of the UV mirror 220, avoids dust to adhere on the UV mirror 220, when personnel leaves the observation window 140, the infrared sensor 150 detects the leaving of personnel, starts the driving part 270, drives the cover plate 260 to close, simultaneously, the high-speed fan 240 is closed.
