Problems solved by technology
[0003] However, as mentioned above, if the protection pipe is used as an indicator of buried objects, the protection pipe will often deviate from its original position during the ground excavation construction process, and when the operator performs excavation work in this case, he cannot accurately detect it with the naked eye. Determine the location of underground pipelines, so there is a problem of possible damage to underground buried pipelines
[0004] At the same time, when working at night or in bad weather, operators will be limited to confirm the position of the protection pipe with the naked eye, which will eventually lead to a decrease in the function and usability of the buried object indicator

Embodiment Construction
[0018] Such as Figure 1-4 As shown, the present invention includes: a fixed cone 10, a container 20 and an upper cover 30, the fixed cone 10 is sealed and installed at the lower opening of the container 20, and the upper cover 30 is sealed and installed at the upper opening of the container 20, and the container 20 passes through The fixed cone 10 is fixedly buried in the ground close to the buried object, and several air outlets 31 are arranged on the top of the upper cover 30, and a layer is covered to seal the several air outlets 31 on the top of the upper cover 30. The film 40 is provided with a seesaw 32 on each air outlet 31 that can break the film 40 by flipping, and several mounting holes 33 are opened on each side of the upper cover 30. A set of turning mechanism 50 is housed in the hole 33, and the turning mechanism 50 includes a rotating shaft 51 pierced in the mounting hole 33, and a rotating rod 52 is fixedly connected to the part of the rotating shaft 51 outside...

The invention relates to an underground embedded object indicator for accurately indicating the position of underground embedded pipelines. The underground embedded object indictor comprises a fixing cone, a container and an upper cover; the container is fixedly embedded in the underground close to the position of the embedded object by the fixing cone; a plurality of air outlets are arranged on the top of the upper cover; a layer of thin film which seals off the plurality of air outlets covers the top of the upper cover; each air outlet is provided with a seesaw which can burst the thin filmthrough overturning; each side of the upper cover is opened with a plurality of installing holes; and each installing hole is internally provided with a set of overturning mechanism which comprises arotating shaft arranged in the installing hole in a penetrating way, a rotating rod, a rotating block, a pricking pin and an air pocket. After the indicator is used, when excavation and construction of the ground surface is carried out and soil collapse around the pipeline touches the rotating rod of the periphery of the upper cover, the rotating rod rotates and drives the rotating block to swing, thus causing the pricking needle under the rotating block to puncture the air pocket so as to release gases or smoke which are easily distinguished.
Description
technical field [0001] The invention relates to the field of underground buried object indicating equipment, in particular to an underground buried object indicator used to accurately indicate the position of underground buried pipelines. Background technique [0002] At present, when various pipelines such as city gas, tap water, sewer or electrical communication cables are buried underground, in order to mark their positions, it is necessary to install underground indicators at the same time. Traditionally, as such an underground buried object indicator, protective pipes made of plastics are mainly used at present. The plastic protective pipes used as indicators of traditional buried objects are located above various buried pipelines. When excavating the ground, these protective pipes will be dug first to inform the operators that there are pipelines buried below. To prevent pipeline damage due to construction. [0003] However, as mentioned above, if the protection pipe...
