Abstract

The invention discloses a water drainage pipeline internal diameter detector. The water drainage pipeline internal diameter detector comprises a fixed cylinder, a limiting cylinder which is arranged in the fixed cylinder, a truncated cone-shaped movable block and a fixed base, wherein a steel ball is rotatably arranged at the bottom of the limiting cylinder and is locally protruded out of the bottom end of the fixed cylinder, and a spring is arranged in the fixed cylinder; and the truncated cone-shaped movable block and the fixed base are connected with the movable end of the spring, the movable block is connected with the fixed base by virtue of a calibrated scale, a plurality of protrusions are arranged on the outer wall of the movable block, a plurality of grooves matched with the protrusions are formed in the inner wall of the fixed cylinder, and rolling balls are rotatably arranged on the upper surface of the fixed base. When the axis of the fixed cylinder is superposed to a straight line in which the diameter of the pipeline is positioned, data on the calibrated scale can be read, and the data is the displacement of the movable block generated by performing linear motion; and by virtue of calculation, the inner diameter size of the pipeline is equal to a straight-line distance from the bottom end of the steel ball to the top end of the rolling ball minus the linear displacement generated by the movable block.

Description

Drainage pipeline inner diameter measurement device
Technical field
The present invention relates to a kind of measurement mechanism, specifically refer to drainage pipeline inner diameter measurement device.
Background technology
PCCP pipe is the strong concrete tube core winding compressor wire with steel cylinder; spray is with cement mortar protective course; adopt steel bell and spigot; welded together with steel cylinder; fluted and the cushion rubber of bell and spigot defines the flexible joint of slidingtype cushion rubber; be the composite structure of steel plate, concrete, high tensile steel wire and sand-cement slurry different materials composition, there is steel and concrete characteristic separately.Prestressed concrete cylinder pipe have compound structure, bear the characteristics such as interior external pressure is higher, joint tighness good, shock resistance is strong, easy to maintenance, pay close attention to by engineering circles, be widely used in long interval water conveying tunnel, pressure inverted-siphon, urban water supply engineering, industry pressure water conveyer pipeline, electric power plant circulating water engineering sewer pipe, pressure blowdown main etc.The advantages such as compared with tubing in the past, PCCP has applied widely, and the economic life is long, anti-seismic performance good, easy for installation, to run expenditure low, substantially water-tight.
At present after PCCP pipe production completes, micrometer inside caliper is generally adopted to measure pipe internal diameter and bell and spigot ovality.Micrometer inside caliper is made up of micrometer head and extension bar, turns varying dimensions, inconvenient operation because micrometer head armrest is dynamic, and reading is not directly perceived, fragile in high-frequency service condition.And micrometer inside caliper acquisition price is higher.
Summary of the invention
The object of the present invention is to provide drainage pipeline inner diameter measurement device, conveniently measuring error is reduced to the Quick Measurement of internal diameter of the pipeline simultaneously, and then reach object that is efficient, that accurately measure.
Object of the present invention is achieved through the following technical solutions:
