Heat resistance warning cone for heating pipeline repair well opening

Abstract

The invention discloses a heat resistance warning cone for a heating pipeline repair well opening. The heat resistance warning cone comprises a warning cone body and a support seat, wherein the support seat comprises a first support ring and a second support ring, the first support ring and the second support ring are connected through a plurality of connecting rods, a first support rod and a second support rod are arranged in the first support ring, the two ends of the first support rod and those of the second support rod are respectively connected with the inner wall of the first support ring, the lower end surfaces of the first support rod and the second support rod are in contact with the ground, the upper end surface of the second support ring is provided with an annular convex edge, the cross section of the annular convex edge is in a round shape, a plurality of clamp buckles are arranged on the lower end surface of the warning cone body, each clamp buckle comprises a first connecting sheet and a second connecting sheet, a gap allowing the annular convex edge to pass is formed between each first connecting sheet and the corresponding second connecting sheet, and the first support ring, the second support ring, the connecting rods, the first support rod and the second support rod are respectively made of metal materials. The heat resistance warning cone for the heating pipeline repair well opening can be used for a long time on high-temperature well covers for warning passing pedestrians, and the occurrence of injury accidents can be reduced.

Description

technical field [0001] The invention relates to a warning device, in particular to a heat-resistant warning cone for wellhead maintenance of thermal pipelines. Background technique [0002] For the sake of the beauty of the city, more and more thermal pipelines are buried underground. Correspondingly, some thermal pipeline maintenance wellheads will be installed on the ground, and manhole covers are placed on the wellheads. However, the existing manhole covers are single-layer ordinary manhole covers. It is made of cast iron, iron plate or cement. It is no problem to use it in the general wellhead, but when it is used in the thermal wellhead, because its thickness is relatively thin and basically not insulated, the surface temperature of the well cover will follow the temperature inside the thermal well. Changes, often the temperature is high, often burn the feet of passers-by on the manhole cover, if the shoes are thicker, it does not matter, if it is sandals or bare feet, ...

[0002] For the sake of the beauty of the city, more and more thermal pipelines are buried underground. Correspondingly, some thermal pipeline maintenance wellheads will be installed on the ground, and manhole covers are placed on the wellheads. However, the existing manhole covers are single-layer ordinary manhole covers. It is made of cast iron, iron plate or cement. It is no problem to use it in the general wellhead, but when it is used in the thermal wellhead, because its thickness is relatively thin and basically not insulated, the surface temperature of the well cover will follow the temperature inside the thermal well. Changes, often the temperature is high, often burn the feet of passers-by on the manhole cover, if the shoes are thicker, it does not matter, if it is sandals or bare feet, it is easy to burn, the same is true for passing pets, but no market has been found so far There is a solution to this problem

In order to prevent people and animals from being harmed, the existing practice is to install a warning post of polymer material on the manhole cover. It is okay at the beginning, but as time goes by, due to the high temperature of the manhole cover, the lower part of the warning post will soften and collapse. After a period of time, the entire column will lie on the manhole cover in a flat image, which cannot play a warning role and affects the appearance
