If the position of the subsequent observation instrument changed, the protection device needed to be disassembled and the aiming direction would be changed, which was a cumbersome process. In addition, during the long-term monitoring process, the prism needed to be regularly maintained and serviced. Traditional protection devices needed to be disassembled for each maintenance, which affected the work efficiency.

[0003] CN221101126U discloses an observation point prism protection device, including an upper protective cover, a lower protective cover, and a bottom protective cover connected in sequence from top to bottom, wherein the upper protective cover is bolted to the lower protective cover, and the lower protective cover is bolted to the bottom protective cover; the upper protective cover is provided with a window A, and the lower protective cover is provided with a window B. The patent realizes effective protection of the double-layer prism by protecting the upper prism and the lower prism respectively through the upper protective cover and the lower protective cover, and the upper protective cover and the lower protective cover are respectively provided with windows to facilitate the use of the prism. However, the observation window of the patent cannot be rotated, and it is not convenient for maintenance.

[0004] Therefore, developing a portable prism protection device has become an urgent problem to be solved. Utility Model Content

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific preferred embodiments.

[0026] like Figures 1 to 5 As shown, a portable prism protection device comprises a stainless steel cylinder 1 and a hemispherical protection cover 2. The hemispherical protection cover 2 is also made of stainless steel.

[0027] A base 11 is welded to the bottom of the stainless steel cylindrical tube 1, and the base 11 is connected to the prism platform. Preferably, the base 11 is fixedly connected to the prism platform by anchor screws 12. A circular slide groove 13 is provided at the top of the stainless steel cylindrical tube 1.

[0028] The hemispherical protective cover 2 is arranged above the stainless steel cylindrical barrel 1, and is slidably connected with the stainless steel cylindrical barrel 1 through a circular slide 13. The hemispherical protective cover 2 can achieve 360° sliding on the stainless steel cylindrical barrel 1; an observation window 3 is arranged on the hemispherical protective cover 2, and the observation window 3 is located at the bottom side wall position of the hemispherical protective cover 2, so that the instrument can observe the prism in the hemispherical protective cover 2. When in use, the observation window 3 is rotated by rotating the hemispherical protective cover 2, which is convenient for observation. When maintenance is required, the hemispherical protective cover 2 can be directly picked up for maintenance. For this purpose, a fixed switch can also be set, and the stainless steel cylindrical barrel 1 and the hemispherical protective cover 2 are connected through a fixed switch. When rotating, the fixed switch is in an open state, which is convenient for rotation and maintenance. When fixed, the fixed switch is in a closed state, and the hemispherical protective cover 2 cannot rotate and is fixed on the stainless steel cylindrical barrel 1.
