Abstract

The present invention discloses a hydraulic power type reservoir dam body surface deformation continuous monitoring device. The hydraulic power type reservoir dam body surface deformation continuous monitoring device comprises a supporting portion I, a supporting portion II, a hydraulic power driving portion and a detection portion; the supporting portion I and the supporting portion II are arranged on the surface of a dam body; the hydraulic power driving portion is installed on the supporting portion I and the supporting portion II; and the detection portion is arranged on the hydraulic power driving portion. According to the hydraulic power type reservoir dam body surface deformation continuous monitoring device of the invention, hydraulic power driving is adopted, a rope stretches and contracts so as to determine the limit positions of the movement of movable plates, so that the deformation condition of the surface of the dam body can be monitored repeatedly. With the device adopted, detection can be performed continuously, and the defect of incapability of performing continuous detection of a current manual detection process can be eliminated. Compared with a method according to which monitoring instruments are embedded, the detection range of the device of the invention is not single points of single monitoring instructions, but the surface of the whole reservoir dam body, and the operability and stability of dam body surface deformation can be improved. The hydraulic power type reservoir dam body surface deformation continuous monitoring device is especially suitable for environments where the safety factor of a dam body is lower, and detection requirements are high. The hydraulic power type reservoir dam body surface deformation continuous monitoring device can assist in decreasing manual labor intensity and has a certain promotion value.

Description

technical field [0001] The invention relates to a continuous monitoring device for surface deformation of a hydraulic reservoir dam body, in particular to a detection environment with hidden safety hazards of the dam and large surface area and relatively high real-time automaticity of detection. Background technique [0002] As a key hub project of a major water conservancy project, the stability and safety of the dam is directly related to the normal operation of other auxiliary projects of the entire water conservancy project, and directly affects and determines the overall safety and design benefits of the major water conservancy project. Its stability and safety are directly related to the life and property safety of the people in the downstream area, social and economic construction and ecological environment safety. [0003] After concrete dams and masonry dams are built and used as water storage reservoirs, the dam body will inevitably deform under the effects of wate...

[0005] In order to solve the problems mentioned in the above-mentioned background technology, the present invention provides a continuous monitoring device for the surface deformation of a hydraulic reservoir dam, which can continuously detect and overcome the shortcomings that cannot be continuously detected in the current manual detection process. At the same time, the device Compared with the method of burying monitoring instruments, the detection range is not a single point of a single detection instrument, but the surface of the entire reservoir dam body. The data obtained by monitoring is more comprehensive, and the deformation of the entire dam body surface can be obtained most comprehensively. It overcomes the limitations of the representativeness of the data detected by the buried monitoring instrument and the shortcomings of laborious maintenance, and improves the operability and stability of the surface deformation of the dam body, especially suitable for dams with low safety factors and high detection requirements. High environment, reduce labor intensity, has a certain value of promotion and use
