Description

Technical Field

[0001] This utility model relates to the field of pipeline measurement technology, and in particular to a tool for measuring the width of fluid level in a circular pipeline. Background Technology

[0002] In current technology, downhole operations remain a crucial method for obtaining pipeline parameters in underground pipeline surveying to determine the cross-sectional area of ​​fluids within the pipeline. However, this traditional method presents several unresolved issues. Firstly, downhole operations pose significant safety hazards. The enclosed environment of underground pipelines often presents risks such as oxygen deficiency and the accumulation of harmful gases like hydrogen sulfide and methane, which can easily lead to poisoning, suffocation, or even explosions, severely threatening the lives of workers. Secondly, the operation process is extremely inconvenient. The confined, damp, and dark underground space restricts worker movement, hindering the flexible operation of measuring instruments. Frequent adjustments to the measurement position further reduce efficiency. Furthermore, the presence of bottom sediment in the pipeline makes it difficult to accurately measure the distance from the liquid surface to the bottom of the pipeline for cross-sectional area calculations, sometimes even making it impossible to locate the very bottom. Since the sediment surface is often parallel to the liquid surface, the distance between the sediment and the liquid surface is relatively easy to measure. If the width of the liquid surface can be obtained, the cross-sectional area of ​​the fluid can be calculated more conveniently.

[0003] Therefore, there is an urgent need for a measuring tool that can effectively solve the problems of well operations. Utility Model Content

[0023] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0024] Example: Figure 1 and Figure 2 As shown, a tool for measuring the width of fluid level in a circular pipe includes a first measuring element 1 and a second measuring element 2;

[0025] The first measuring component 1 includes a first leg 11, a second leg 12, a hinge 13, a telescopic sleeve 14, and a measuring tape 15. The first leg and the second leg are hinged to the hinge. A first hinge part 111 is fixed to the first leg and the second leg. The telescopic sleeve is fixedly connected to the bottom of the hinge. The telescopic sleeve includes a fixed rod 141 and a telescopic rod 142. The telescopic rod is embedded in the fixed rod, and a second hinge part 143 is fixed to the telescopic rod and connected to the first hinge part of the first leg and the second leg. The measuring tape has uniform graduations and is fixed to the telescopic sleeve.

[0026] The second measuring component includes several detachably connected stainless steel tubes 21 with graduations. The topmost stainless steel tube passes through the telescopic rod and fixed rod of the first measuring component and is connected to the bottom of the hinge.

[0027] After the first and second legs of the first measuring piece are hinged to the hinge, they can rotate 0-90° on the plane along the hinge point. Since the second hinge part fixed on the telescopic rod is connected to the first hinge part of the first and second legs, the first and second legs are always symmetrical about the central axis of the telescopic sleeve.

[0028] The second hinge component of the telescopic rod is connected to the first hinge component of the first and second legs using a carbon fiber rod. The carbon fiber rod is a high-strength carbon fiber rod.

[0029] The fixed rod and the telescopic rod in the telescopic sleeve are connected by a slide rail, and the outer diameter of the telescopic rod is smaller than the inner diameter of the fixed rod.

[0030] The measuring tape is made of fiberglass. It features metric graduations and markings, all made of fluorescent material.

[0031] The hinge has a threaded knob at the bottom for threaded connection to the top of the stainless steel tube, and a threaded knob at the tail of the stainless steel tube for threaded connection to the top of another section of the stainless steel tube. Each section of the stainless steel tube has the same graduations and dimensions. The stainless steel tube has uniform graduations.

[0032] When using this invention for pipeline measurement, first connect the graduated stainless steel round tube 21 of the second measuring component 2 to the bottom of the hinge 13. Increase the number of stainless steel round tubes 21 as needed on site. After connection, place the stainless steel round tube 21 vertically upwards with the hinge below into the inspection well. At this point, the user needs to hold the stainless steel round tube 21 and the measuring tape 15 with both hands.

[0033] After the first measuring piece 1 is brought close to the opening of the pipe to be measured, the user can pull the measuring tape 15 appropriately along the axis of the stainless steel round pipe. The measuring tape 15 drives the telescopic rod 142 upwards. Because the telescopic rod 142 is connected to the first support leg 11 and the second support leg 12 by a rigid connecting rod, the first support leg 11 and the second support leg 12 will open to both sides around the axis of the telescopic rod 142, forming a stable triangular structure between the support leg, telescopic sleeve, and connecting rod. Furthermore, the triangles formed by the first support leg 11 and the second support leg 12 are congruent triangles. The apex of the first support leg 11 is positioned at the leftmost side of the liquid surface in the pipe, and the apex of the second support leg 12 is positioned at the rightmost side of the liquid surface in the pipe. At this time, the user can select any scale a on the measuring tape 15, bring the measuring tape appropriately close to the stainless steel round pipe 21, and record the corresponding scale b on the stainless steel round pipe at scale a.

[0034] Furthermore, after the user relaxes the measuring tape, the first leg 11 and the second leg 12 are retracted. After the measuring tool is taken out of the inspection well, it is placed flat on an open ground. The user pulls the scale a of the measuring tape to the scale b of the stainless steel tube. While maintaining stability, the user can use the measuring tape to measure the distance L between the top of the first leg 11 and the top of the second leg 12. This distance is the length of the liquid surface width.

[0035] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
