Description
Technical Field
The utility model relates to a maintenance technique of power supply line specifically is a bury cable warning device.
Background
In modern town construction, underground cables are laid as a mainstream of power line construction because the underground cables do not affect space utilization above lines and the cables are erected in an empty manner with high safety. However, the laying of the underground cable is often parallel to the underground lines such as the communication cable and the buried pipeline, and when the communication cable or the underground pipeline is constructed in the later stage, the ground surface on which the underground power supply cable is laid in the earlier stage needs to be excavated to lay the pipeline in the later stage. Thus, the cable laid in the earlier stage is easily broken, and unnecessary loss is caused. At present, in order to prevent an underground cable from being damaged in repeated line construction, a 'line corridor' mark is arranged on the ground surface of the underground cable, but the ground surface warning mark is usually damaged or lost due to the fact that operation and maintenance are not in place, so that the underground cable is not protected, and potential safety hazards are left.
Disclosure of Invention
The utility model aims at providing a bury cable warning device, bury this device underground through the certain degree of depth in underground cable top, can play certain warning effect daytime or when being under construction night, warning effect is directly perceived, reliable, can effectively avoid constructor to dig disconnected supply cable, has economy, effective, be difficult for losing, simple accurate characteristics.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
an underground cable warning device comprising: the underground warning explosion tube is arranged above an underground cable in parallel, the whole underground warning explosion tube is a transparent PVC round tube sealed by high-pressure inert gas, the distance between the axis center and the lower part of the underground cable is 300-500 mm, a noctilucent powder layer is coated on the inner surface of the underground warning explosion tube, the length of the underground warning explosion tube is 500-1000 mm, the diameter of the underground cable is 50-100 mm, the wall thickness of the underground cable is 3-8 mm, and a mixture of noctilucent powder and pigment powder is placed inside the underground warning explosion tube.
The high-pressure inert gas is neon, and the pressure of the neon sealed in the underground warning explosion tube is 0.15-0.2 MPa.
The coating is composed of zinc sulfide noctilucent powder, the thickness of the coating is 200-500 microns, the mass of the noctilucent powder is 50-100 g, and the particle size of the noctilucent powder is 10-50 microns.
The pigment powder is orange inorganic pigment powder, the mass of the pigment powder is 50-100 g, and the particle size of the pigment powder is 10-30 microns.
The principle of the utility model is as follows: according to the depth of each digging of the excavator, the device is suitable to be buried 0.3-0.5 m above the laid cable, and when the device is constructed in the daytime, the length and the shape of the device are similar to those of a pipeline sheath, so that the device is easy to attract the attention of constructors and has a protection function; meanwhile, the construction machinery is also very likely to damage the warning pipe explosion to cause the pipe explosion to burst, and the noctilucent powder and the pigment powder stored in the pipe are sprayed together to form a striking warning smoke screen, so that the attention of constructors is brought; during the night construction, when this device was dug out, because zinc sulfide night light powder coating has high photosensitivity, under the weak light source during the construction, also can give out light rapidly, perhaps spout luminous smoke screen to arouse constructor's attention.
The utility model has the advantages that: through burying this device underground at certain degree of depth in underground cable top, can play certain warning effect when being under construction daytime or night, warning effect is directly perceived, reliable, can effectively avoid constructor to dig disconnected supply cable, has economy, effective, be difficult for losing, simple accurate characteristics.

Fig. 2 is an enlarged view of fig. 1 at D.
In the figure, 1, a buried warning explosion tube, 2, a luminous powder layer, 3, a mixture of luminous powder and pigment powder, 4 and inert gas.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, an underground cable warning device includes: parallel arrangement buries warning booster 1 in underground cable top, as shown in fig. 1, bury warning booster 1 wholly for sealing the transparent PVC pipe that has high-pressure inert gas 4 underground in an embodiment of the utility model, its axis center is 500 millimeters apart from the underground cable of below, and its inner surface is brushed with night light powder layer 2, and its length is 1000 millimeters, and the diameter is 100 millimeters, and the wall thickness is 5 millimeters, and it is still inside places night light powder and pigment powder's mixture 3, and this mixture 3 is the physical mixture. The combination of the structure and the material can emit light and can emit a warning smoke screen after bursting.
In one embodiment of the present invention, the high pressure inert gas 4 is neon, and the pressure of the neon sealed in the underground warning explosion tube 1 is 0.2 mpa. So as to avoid injury to human body or equipment.
In an embodiment of the utility model, the night light powder is zinc sulfide night light powder, and its coating thickness is 200 ~ 500 microns, and the quality of night light powder is 100 grams, and the granularity of night light powder is 10 ~ 50 microns.
