Background
In the construction stage and the operation stage of the large-scale hydraulic and hydroelectric engineering, key positions of a hydropower station are needed, such as: the key parts such as a barrage, a left bank dam abutment, a right bank dam abutment, a front side slope of the dam, a rear side slope of the dam and the like perform stable deformation monitoring work, the whole monitoring process is throughout the whole life cycle of the hydropower station, and data support is provided for ensuring stable operation of the hydropower station. The monitoring mode of the large hydropower station at the present stage is that a high-precision total station and a prism monitor each engineering part by adopting a front intersection method, and each monitoring point on a monitoring body needs to be observed from 2-3 different working base points according to the standard requirements in order to ensure the authenticity, accuracy and precision of monitoring data. Therefore, when monitoring is performed each time, the rotation and alignment work of the prisms in different observation directions are needed to be carried out by the cooperation of a person at the monitoring point, and because more prisms are used in the monitoring work, the time consumption is long each time, and more manpower and material resources are needed to be input for cooperation to complete the monitoring work for erecting, aligning and dismantling the prisms each time.
Along with the development of science and technology and the progress of society, aiming at the problems of more personnel investment and long monitoring time consumption existing in the existing prism monitoring means, the development of a coaxial polygon mirror device for deformation monitoring is needed to solve the problem that personnel are required to go to a monitoring point to perform prism rotation and alignment in the field during each monitoring.
Disclosure of Invention
Aiming at the defects of the prior art, the utility model provides a coaxial polygon mirror device for deformation monitoring, which comprises a forced centering disc, a U-shaped bracket, a Shan Laika joint, a double-coated clamping joint and a prism; the structure is as follows: the central wire hole of the forced centering disc is fixed with the screw rod below the single-component clamping connector in a wire connection manner, and the upper end of the Shan Laika connector penetrates into the through hole below the U-shaped bracket and is locked and fixed through the locking nut A; the upper end of the double-coated card connector penetrates through the upper through hole of the U-shaped bracket and is locked and fixed through the locking nut B, and the three prisms are sequentially arranged in the single-coated card connector and the double-coated card connector.
Further, through holes at the upper end and the lower end of the U-shaped bracket are coaxial in the vertical direction.

Description of the embodiments
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
Example 1, as shown in the figure, a coaxial polygon mirror device for deformation monitoring, comprising a forced centering disk 1, a U-shaped bracket 2, a single-come-up joint 3, a double-come-up joint 4, and a prism 5; the structure is as follows: the central wire hole of the forced centering disc (1) is fixed with the lower screw rod of the single-part blocking joint 3 in a wire connection manner, and the upper end of the Shan Laika joint 3 penetrates into the lower through hole 201 of the U-shaped bracket 2 and is locked and fixed through a locking nut A301; the upper end of the double-coated card connector 4 is penetrated into the upper through hole 201 of the U-shaped bracket 2 and locked and fixed through the locking nut B, and the three prisms 5 are sequentially arranged in the single-coated card connector 3 and the double-coated card connector 4.
The through holes 201 at the upper and lower ends of the U-shaped bracket 2 are coaxial in the vertical direction, so that the three installed prisms 5 are ensured to be coaxial.
The U-shaped bracket 2, the single-part clamp connector 3 and the double-part clamp connector 4 are made of stainless steel or aluminum alloy materials, and the stainless steel or aluminum alloy materials ensure that the parts are not rusted, so that the long-term use is convenient.
