Description

Technical Field

[0001] This utility model relates to the field of pipeline sealing detection technology, and in particular to a water level testing device for a closed-loop pipeline test. Background Technology

[0002] In the water tightness test of unpressurized pipelines, according to GB 50268-2008 "Code for Construction and Acceptance of Water Supply and Drainage Pipeline Engineering", the water level observation method involves marking the water level line on the inner wall of the inspection well. However, this method has several drawbacks. When the water level is far from the wellhead, marking requires personnel to climb into the deep well, posing a risk of falls from height. Furthermore, the confined space inside the well makes it difficult to guarantee the accuracy of the marking position. When the water level is close to the wellhead, observation requires a downward viewing angle, which is affected by light refraction and obstruction from the wellhead, resulting in large reading errors. Frequent manual observation by bending over increases the risk of safety accidents and is inefficient. Utility Model Content

[0020] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0021] See Figure 1 and Figure 2 As shown in the figure, this utility model embodiment provides a water level testing device for a closed-loop pipeline test, which includes a main beam 1, a secondary beam 2, a float 3 and a measuring ruler 4.

[0022] Specifically, the main beam 1 and the secondary beam 2 are slidably connected, the secondary beam 2 can slide along the axial direction of the main beam 1, the two ends of the main beam 1 are provided with a first limiting member 11, and the end of the secondary beam 2 near the main beam 1 is provided with a second limiting member 21;

[0023] The main beam 1 is provided with a float support 41, which is slidably connected to the measuring ruler 4. The axial direction of the measuring ruler 4 is perpendicular to the main beam 1. The surface of the measuring ruler 4 is provided with scale units, and the bottom end of the measuring ruler 4 is provided with the float 3.

[0024] Working principle of this utility model embodiment:

[0025] According to the diameter of the pipe opening, the secondary beam 2 slides along the main beam 1, so that the main beam 1 and the secondary beam 2 can be attached to the pipe opening. The float 3 is in contact with the water surface. The measuring ruler 4 stands vertically and slides along the top support 41 of the float. When it is stable, the scale value of the measuring ruler 4 corresponding to the upper edge of the top support 41 of the float is recorded.

[0026] This utility model includes a main beam 1, a secondary beam 2, a float 3, and a measuring ruler 4. The main beam 1 and the secondary beam 2 are slidably connected to form a support rod. A float top support 41 is provided on the main beam 1, and the float top support 41 is slidably connected to the measuring ruler 4. The float 3 at the bottom of the measuring ruler 4 floats on the water, allowing the measuring ruler 4 to stand vertically. The scale value of the measuring ruler 4 corresponding to the upper edge of the float top support 41 at this time is recorded. The entire measurement process is intuitive and efficient, and can effectively ensure the personal safety of the test personnel.

[0027] In some embodiments, a first limiting member 11 near the protruding end of the sub-beam 2 is provided with a mounting hole 12, and a fastener 13 is provided on the mounting hole 12, the fastener 13 being able to abut against the surface of the sub-beam 2.

[0028] After fixing the extension lengths of the secondary beam 2 and the main beam 1, tighten the fasteners 13 set on the mounting holes 12 to increase the friction between the main beam 1 and the secondary beam 2, so that the main beam 1 and the secondary beam 2 can maintain their extension lengths. This solves the problem that during use, the secondary beam 2 may retract into the main beam due to collision and fall into the pipe.

[0029] See Figure 3 and Figure 4 In some other embodiments of this utility model, the main beam 1 and the secondary beam 2 form a load-bearing beam, and the two ends of the load-bearing beam are provided with fixed feet 5 vertically. The fixed feet 5 can limit the position of the load-bearing beam, so that the load-bearing beam can be stably fixed on the wellhead.

[0030] Preferably, both the main beam 1 and the secondary beam 2 are hollow structures. A guide post 6 is provided inside the main beam 1, with its axial direction aligned with that of the main beam 1. The guide post 6 passes through the second limiting member 21 and extends into the secondary beam 2. A spring member 7 is fitted onto the guide post 6. One end of the spring member 7 is fixedly connected to the first limiting member 11 away from the secondary beam 2, and the other end is fixedly connected to the second limiting member 21. It should be noted that the spring member 7 is a tension spring, providing continuous force to cause the secondary beam 2 to slide towards the main beam 1.

[0031] The second limiting member 21 has a guide protrusion 22 on its side, and the main beam 1 has a guide rail 14 on its inner wall. The guide protrusion 22 is slidably connected to the guide rail 14. The guide protrusion 22 and the guide rail 14 cooperate to guide the sliding motion and solve the problem of jamming that easily occurs during use.

[0032] Preferably, the measuring ruler 4 is in the shape of a strip or a cylinder.

[0033] Preferably, the scale on the measuring ruler 4 gradually decreases from bottom to top.

[0034] Preferably, the float 3 is a sphere or cube made of a material with a density less than that of water, and the top of the float 3 is fixedly connected to the measuring ruler 4.

[0035] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
