Description
Technical Field
The invention belongs to the technical field of municipal pipeline detection, and particularly relates to a device for measuring the pipe diameter and the fullness of an underground drainage pipeline, which is particularly suitable for measuring when an inspection well is full of water or does not have a downhole condition.
Background
When the drainage pipeline of the current city is checked, basic data such as the pipe diameter and the fullness of the pipeline are required to be known frequently, and an accurate basis is provided for hydraulic calculation of a pipe network. Particularly, when the flow rate of a pipeline is measured, the flow rate of sewage can be obtained by using a flow meter probe, and the flow rate can be calculated according to a flow calculation formula (Q ═ a × V). The current popular method for measuring the pipe diameter of the drainage pipe is that a groping person uses an L-shaped rod to extend into a well on the ground to hook and measure the height difference of the upper inner wall and the lower inner wall of the pipeline, if a well chamber is large, the L-shaped rod extends into a pipe orifice from a well mouth to have an overlarge inclination angle, measurement deviation is generated, and when the inspection well is full of water or silted, measurement cannot be carried out. The fullness is basically estimated and read by naked eyes at a wellhead or by a QV periscope, and when a well chamber is deep or the light is dark, the accuracy of estimating and reading the fullness by the naked eyes is very low.
The utility model with the Chinese patent number ZL202120446065.4 discloses an underground pipeline pipe diameter measuring device which comprises a telescopic measuring device, a movable clamping rod, a supporting groove and a push-pull device; the telescopic measuring device comprises a transverse telescopic arm and a longitudinal telescopic arm, and the longitudinal telescopic arm is movably embedded in the transverse telescopic arm; the telescopic measuring device is connected with the movable clamping rod through a telescopic rotating shaft; the movable clamping rod is connected with the push-pull device through the push-pull rotating shaft; the telescopic measuring device is fixedly arranged at the bottom of the supporting groove; the push-pull device is movably arranged in the supporting groove. The scheme can be only used for measuring the pipe diameter of the three-dimensional pipeline which is not full of water or silted, and the fullness cannot be measured. The pipe diameter measuring accuracy is improved to a certain extent by the scheme, but the structure of the pipe diameter measuring device comprises too many telescopic rods and telescopic shafts, the force application direction and the telescopic direction are different, the lines are easy to clamp, and when water flows through the pipe diameter measuring device in a quick state, an acting point of the measuring device is not impacted by the water flow easily, so that the measuring result is influenced.

step three: the fixed rod (1) and the movable rod (2) are extended into the inspection well together, an angle steel (11) at the tail end of the fixed rod (1) is abutted against the bottom of the opening of a drainage pipeline, then the movable rod (2) is operated to enable the measuring rod (3) to be vertically attached to the center line of the opening of the drainage pipeline, and the movable rod (2) is moved up and down to abut against a short hook member (12) at the tail end of the movable rod to the inner top of the drainage pipeline; at the moment, the digital serial number on the measuring rod (3) is read to obtain the fullness and pipe diameter information of the drainage pipeline;
b. when the full water pipe mouth of the inspection well submerges and can not watch the number sequence number on the measuring rod (3), the fifth round hole (9.5) at the upper end of the reading ruler (4) is sleeved in the rotating shaft (8) on the second section hollow steel pipe (7) of the fixed rod (1), so that the reading ruler (4) is naturally vertical to the ground, and the scale at the intersection of the reading ruler (4) and the movable rod (2) is the pipe diameter of the drainage pipeline.
