Description

Technical Field

[0001] The utility model relates to the field of pipe network defect detection, in particular to an underground pipe network defect detection device. Background Art

[0002] At present, underground pipeline inspection is to control the equipment equipped with cameras to go deep into the pipeline, take the image data inside the pipeline and transmit it to the monitor on the ground through the signal cable. The operator can judge the damage of the pipeline and the approximate location through the monitoring system on the ground. Among them, the QV periscope is mainly used for rapid inspection of the internal situation of the pipeline. It is suitable for pipelines with a diameter of 150mm-2000mm. When using it, the operator does not need to go down the well;

[0003] When using a portable QV periscope (such as Figure 4 When inspecting the pipeline network, a person needs to hold a hand-held rod 14 to lower the pipeline periscope 1 connected at the bottom along the wellhead of the pipeline 13. After going deep, the supporting legs 3 on the side of the pipeline periscope 1 are used to support it to prevent impurities in the pipeline 13 from contaminating the pipeline periscope 1. However, since the supporting legs 3 are relatively simple, they are easy to shake when supporting the pipeline periscope 1, affecting the observation effect of the periscope. Utility Model Content

[0004] In order to solve the above-mentioned problems, the utility model provides an underground pipe network defect detection device.

[0005] The utility model is realized through the following technical solutions:

[0006] An underground pipe network defect detection device includes a pipeline periscope and a support leg fixed to its side by a connecting frame, a stabilizing support assembly is arranged at the bottom of the support leg, the stabilizing support assembly includes a stabilizing rod laterally arranged at the lower part of the support leg, and a buffer assembly is arranged on the stabilizing rod.

[0007] Further optionally, a sliding sleeve sleeved on the supporting leg is arranged at the center of the stabilizing rod, and a sliding block matching with the sliding groove on the supporting leg is arranged on the inner side of the sliding sleeve.

[0008] Further optionally, the buffer assembly includes a compression spring sleeved on the support leg, the bottom of the compression spring fits with the top of the sliding sleeve, and the top of the compression spring fits with the limit block 0 fixed on the support leg.

[0009] Further optionally, rubber sleeves are sleeved on both sides of the stabilizer bar, and a plurality of protrusions are arranged on the bottom of the rubber sleeves.

[0010] Further optionally, the stabilizing rod is arranged perpendicular to the observation direction of the pipeline periscope.

[0011] Further optionally, the stabilizer bar is tilted on both sides and is made of stainless steel.

[0012] Compared with the existing technology, the beneficial effect of the utility model is: the utility model arranges a stable support component at the lower part of the support leg of the pipeline periscope of the detection pipeline, so that the support leg forms a triangular support for the bottom of the pipeline, which greatly improves the stability of the support of the support leg, thereby avoiding the shaking of the pipeline periscope and ensuring the observation effect of the pipeline periscope.

DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0019] like Figure 1 As shown, an underground pipe network defect detection device includes a pipeline periscope 1 and a support leg 3 whose side is fixed by a connecting frame 2, a stabilizing support assembly 4 is arranged at the bottom of the support leg 3, and the stabilizing support assembly 4 includes a stabilizing rod 5 laterally arranged at the lower part of the support leg 3, and a buffer assembly is arranged on the stabilizing rod 5.

[0020] like Figure 2 , 3 As shown, a sliding sleeve 6 is provided in the center of the stabilizing rod 5 and is sleeved on the supporting leg 3. A sliding block 7 is provided inside the sliding sleeve 6 and matches with a sliding groove 8 on the supporting leg 3. This can prevent the stabilizing rod 5 from rotating and ensure that it is fixed in one direction.

[0021] like Figure 2 As shown, the buffer assembly includes a compression spring 9 sleeved on the support leg 3, the bottom of the compression spring 9 fits with the top of the sliding sleeve 6, and the top of the compression spring 9 fits with the limit block 10 fixed on the support leg 3. The compression spring 9 ensures that the stabilizing rod 5 is pressed tightly against the supports on both sides of the pipeline.

[0022] like Figure 2 As shown, rubber sleeves 11 are sleeved on both sides of the stabilizing rod 5, and a plurality of protrusions 12 are arranged at the bottom of the rubber sleeve 11. The rubber sleeve 11 and the protrusions 12 at the bottom thereof can increase the friction between the stabilizing rod 5 and the bottom of the pipe to avoid the sliding influence of the sludge from the pipe to the bottom.

[0023] like Figure 1 As shown, the stabilizing rod 5 is arranged perpendicular to the observation direction of the pipeline periscope 1, so that the lowered pipeline periscope 1 always keeps the same direction as the pipeline, and the observation of the pipeline is more stable. The stabilizing rod 5 is inclined on both sides and is made of stainless steel.

[0024] The implementation principle of an underground pipe network defect detection device in the embodiment of the present application is:

[0025] When using the pipeline periscope 1 to inspect the wellhead of the pipeline 13, hold the hand-held rod 14 to lower the pipeline periscope 1 into the pipeline 13, and support the support leg 3 on one side of the pipeline periscope 1 at the bottom of the pipeline 13 to ensure that the pipeline periscope 1 is in the center of the pipeline 13;

[0026] When the support leg 3 contacts the bottom of the pipe 13, the stabilizing rod 5 of the stabilizing support assembly at the lower part of the support leg 3 will be supported on both sides of the bottom of the pipe 13. As the support leg 3 moves downward, the stabilizing rod 5 will squeeze the compression spring 9 upward. The compression spring 9 can always keep the stabilizing rod 5 in close contact with both sides of the bottom of the pipe 13 to maintain a stable support for the support leg 3. In addition, the bottom support of the support leg 3 forms a triangular support as a whole, which greatly improves the stability of the support leg 3 and ensures the observation effect of the pipeline periscope 1.

[0027] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model.
