Pumped storage power station inclined shaft tunnel appearance inspection and measurement device and arrangement method

Abstract

The invention provides a pumped storage power station inclined shaft tunnel appearance inspection and measurement device and an arrangement method. The arrangement method comprises the following stepsthat S1, a measurement trolley is installed on a lower adit section in a tunnel; S2, driving equipment is installed at a preset position outside a ventilation wellhead; S3, according to the moving track of the bearing rope, guide wheels are arranged at the corners of the wall of the tunnel correspondingly; and S4, a balance weight is installed at a bottom end of the bearing rope, the bottom end of the bearing rope is lowered to the lower adit section in the tunnel from the ventilation wellhead to be connected with the measuring trolley, and the measuring trolley is dragged through the bearingrope to observe the wall of the inclined shaft. The method is advantaged in that an appearance detection problem of an existing large-dip-angle large-diameter inclined shaft is solved, risks caused in the manual detection process in the prior art are avoided, and the method has advantages of being simple in structure, easy to operate, good in detection effect and the like.

Description

technical field [0001] The invention relates to the technical field of tunnel detection, in particular to an appearance inspection and measurement device and arrangement method for an inclined shaft tunnel of a pumped storage power station. Background technique [0002] The pumped storage power station is a hydropower station that uses the electric energy to pump water to the upper reservoir when the power load is low, and then releases water to the lower reservoir to generate electricity during the peak power load period. Also known as energy storage hydropower station. It can transform the excess electric energy when the grid load is low into high-value electric energy during the peak period of the grid. It is also suitable for frequency modulation and phase modulation, stabilizing the cycle and voltage of the power system, and it is suitable for emergency backup. It can also improve thermal power plants in the system and the efficiency of nuclear power plants. The const...

Problems solved by technology

However, its detection and construction are difficult. Due to the relatively closed working space, the oxygen content often does not meet the standards required by the human body. If personnel enter the internal work, they often need to carry oxygen cylinders. It is very easy to cause safety accidents when working inside for a long time. High risk has become one of the key technical issues restricting the tunnel inspection of pumped storage power stations, and it has also become a problem that is not easy to solve in the current industry

[0004] Patent document CN110986859A discloses a three-dimensional detection method for tunnels, which relates to the technical field of tunnel detection, and solves the problem that a three-dimensional detection vehicle for tunnels runs based on its own power. Once its power is exhausted, it will be unable to complete the rest of the detection work, which includes: Step S100: The main control terminal starts the tunnel 3D inspection vehicle; Step S200: The main control terminal comprehensively analyzes and determines the tunnel 3D inspection vehicle based on the power condition of the tunnel 3D inspection vehicle and the location of the charging piles installed in the tunnel for the tunnel 3D inspection vehicle to charge. The driving trajectory of the vehicle; step S300: the tunnel three-dimensional inspection vehicle drives according to the driving trajectory determined in step S200, but this design still cannot well realize the detection of long-distance, large-inclination and large-diameter tunnels
