Description

[Technical field]

[0002] The present application relates to the technical field of underground pipelines, and in particular to a tracer plate set capable of being sealed and connected. [Background technology]

[0004] At present, most of the plastic water pipes used to transport tap water and the steel gas pipes used to transport gas are buried deep underground. In order to clearly understand the distribution of the pipeline network buried deep underground, the existing technical means is to bury the tracer line on one side of the pipeline when the pipeline is deeply buried, so as to obtain the underground distribution network of the tracer line to obtain the distribution of each pipeline.

[0005] During the current municipal construction process, construction workers can only learn about the distribution of underground pipelines from the distribution of underground tracer lines, but cannot learn about the buried depth of underground pipelines, which often causes underground pipelines to be cut by excavators during construction, thereby causing water overflow or gas leakage, and even causing serious explosion accidents. Therefore, technical personnel in this field urgently need to develop a tracer plate group that can be buried underground to mark the distribution of underground pipelines and protect the underground pipelines. [Summary of the invention]

[0047] The present application will be further described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0048] As shown in FIGS. 1 to 7 , the sealably connected tracer plate set comprises at least two tracer plates, wherein one of the tracer plates is located above the other tracer plate, the tracer plate located above is the upper tracer plate 1, and the tracer plate located below is the lower tracer plate 2, the upper tracer plate 1 comprises an upper non-conductive body 11 and an upper conductive metal sheet 12 embedded in the upper non-conductive body 11, and the lower tracer plate 2 comprises a lower non-conductive body 21 and a lower conductive metal sheet 22 embedded in the lower non-conductive body 21;

[0049] The sealably connected tracer plate set further comprises a sealing connection mechanism 3 disposed between the upper tracer plate 1 and the lower tracer plate 2 and used for sealingly connecting the upper tracer plate 1 and the lower tracer plate 2 to simultaneously conduct the upper conductive metal sheet 12 and the lower conductive metal sheet 22.

[0050] The sealably connected tracer plate group of the present application seals and connects the upper tracer plate 1 and the lower tracer plate 2 through the seal connection mechanism 3 and simultaneously conducts the upper conductive metal sheet 11 and the lower conductive metal sheet 21, thereby not only realizing the function of marking and tracing the underground pipeline, but also improving the overall strength of the upper tracer plate 1 and the lower tracer plate 2 through the upper conductive metal sheet 11 and the lower conductive metal sheet 21, so that when the present application is laid above the underground pipeline, a strong protective layer can be formed for the underground pipeline, thereby preventing the excavator from directly digging into the underground pipeline, and further ensuring the safety of the underground pipeline to the greatest extent.

[0051] The upper tracer plate 1 is located on the upper side of the lower tracer plate 2, and the upper tracer plate 1 also includes an upper non-conductive body 12 wrapped around the outer side of the upper conductive metal sheet 11. The lower tracer plate 2 also includes a conductive body 12 wrapped around the outer side of the lower conductive metal sheet 21 and

[0052] The upper non-conductive body 12 contacts the lower non-conductive body 22. The sealing connection mechanism 3 includes an upper concave countersunk hole 301, a lower receiving hole 302, a first through hole 303, an upper receiving hole 304, a lower concave limiting hole 305, a second through hole 306, a conductive sleeve 307, a connecting piece 308, a limiting locking piece 309, an upper sealing ring 310, and a lower sealing ring 311. The upper concave countersunk hole 301 is opened downward on the upper side of the upper non-conductive body 12. The lower receiving hole 302 is opened upward on the lower side of the upper non-conductive body 12. The first through hole 303 is opened on the upper conductive metal sheet 11, and its aperture is smaller than the aperture of the lower receiving hole 302. The upper receiving hole 304 is downwardly opened on the upper side of the lower non-conductive body 22, and its hole diameter is equal to the hole diameter of the lower receiving hole 302. The lower upper concave limiting hole 305 is upwardly opened on the lower side of the lower non-conductive body 22. The second through hole 306 is opened on the lower conductive metal sheet 21, and its hole diameter is equal to the hole diameter of the first through hole 303. The conductive sleeve 307 is sleeved between the lower receiving hole 302 and the upper receiving hole 304, and its upper side is in contact with the lower side of the upper conductive metal sheet 11, and its lower side is in contact with the upper side of the lower conductive metal sheet 21. The upper end of the connecting member 308 is sleeved in the upper concave countersunk hole 301, and the lower end thereof passes through the first through hole 303, the conducting sleeve 307, and the second through hole 306 in sequence downwards and is located in the lower concave limiting hole 305. The limiting locking member 309 is clamped in the lower concave limiting hole 305 and connected to the connecting member 308, and is used to limit and lock the connecting member 308. The upper sealing ring 310 is sleeved on the upper end of the connecting member 308, located in the upper concave countersunk hole 301, and is used to seal the gap between the upper concave countersunk hole 301 and the upper end of the connecting member 308. The lower sealing ring 311 is sleeved on the lower end of the connecting member 308, located in the lower concave limiting hole 305 and on the upper side of the limiting locking member 309, and is used to seal the gap between the limiting locking member 309 and the lower concave limiting hole 305 and the lower end of the connecting member 308. The advantage is that it realizes the function of sealing connection and conducting the upper tracer plate 1 and the lower tracer plate 2.

[0053] The lower concave limiting hole 305 and the limiting locking member 309 are both hexagonal in shape, which has the advantage that the limiting locking member 309 can be limited in the lower concave limiting hole 305 to prevent the limiting locking member 309 from shifting. The limiting locking member 309 is connected to the connecting member 308 in a threaded connection, which has the advantage that the upper sealing ring 310, the conductive sleeve 307 and the lower sealing ring 311 can be conveniently locked between the upper non-conductive body 12 and the lower non-conductive body 22, and the tightness between the upper non-conductive body 12 and the lower non-conductive body 22 can be adjusted according to actual use conditions.

[0054] The sealing connection mechanism 3 further includes an upper concave annular groove 312, a lower concave annular groove 313, and an embedded sealing ring 314. The upper concave annular groove 312 is opened upward on the lower side of the upper non-conductive body 12, and is located outside the lower receiving hole 302. The lower concave annular groove 313 is opened downward on the upper side of the lower non-conductive body 22, and is located outside the upper receiving hole 304, and is matched with the upper concave annular groove 312. The embedded sealing ring 314 is embedded between the upper concave annular groove 312 and the lower concave annular groove 313, and is used to seal the gap between the upper non-conductive body 12 and the lower non-conductive body 22. The advantage is that the embedded sealing ring 314 cooperates with the upper concave ring groove 312 and the lower concave ring groove 313 to seal the gap between the upper non-conductive body 12 and the lower non-conductive body 22, thereby preventing underground moisture from penetrating into the conductive sleeve 307 and the upper conductive metal sheet 11 and the lower conductive metal sheet 21, thereby not only preventing short circuits but also improving the stability of normal operation.

[0055] The upper conductive metal sheet 11 and the lower conductive metal sheet 21 are both made of steel, and their thickness is 0.2-5 mm, preferably 0.3 mm. The advantage is that the 0.3 mm thick steel plate will not affect the overall weight of the upper tracer plate 1 or the lower tracer plate 2 due to its excessive weight, and can also make the upper tracer plate 1 or the lower tracer plate 2 have a relatively high overall strength. Even if an excavator digs down to the upper tracer plate 1 or the lower tracer plate 2, the upper tracer plate 1 or the lower tracer plate 2 will not be immediately dug off, thereby maximizing the safety of the underground pipeline.

[0056] The conductive sleeve 307 is made of steel or copper, preferably copper, which has the advantage that copper has better conductivity, thereby further improving the conductivity.

[0057] The upper non-conductive body 12, the lower non-conductive body 22, the connecting piece 308 and the limiting locking piece 309 are all made of plastic, which has the advantages of being insulating and having excellent arc resistance, high and low temperature resistance, and aging resistance.

[0058] The upper sealing ring 310, the lower sealing ring 311 and the embedded sealing ring 314 are all made of silicone, which has the advantages of not only excellent insulation, corona resistance, arc resistance, high and low temperature resistance, and aging resistance, but also outstanding environmental protection and low carbon characteristics.

[0059] The upper side surfaces of the upper non-conductive body 12 and the lower non-conductive body 22 are both provided with a marking warning area 100 , which has the advantage that a warning message for warning can be written in the marking warning area 100 , for example: there is a gas pipeline underneath, excavation is strictly prohibited, etc.

[0060] The sealably connected tracer plate set further comprises a first electrical connection mechanism connected to the first tracer plate for receiving a power source, and a final electrical connection mechanism connected to the final tracer plate for receiving a power source. The advantage is that it is convenient to electrically connect an external power source through the first electrical connection mechanism, and to electrically connect an external detection device through the final electrical connection mechanism.

[0061] In summary, the implementation methods of the present application have been described in detail, but the present application is not limited to the above implementation methods. Even if various changes are made to the present application, they still fall within the protection scope of the present application.
