Self-protection urban heat removal well based on chemical reaction

Abstract

The invention belongs to the field of communal facilities, and particularly relates to a self-protection urban heat removal well based on a chemical reaction. The self-protection urban heat removal well comprises a well body, an annular protection cavity is formed in the side wall of the upper end of the well body, a protection cover is slidably connected in the annular protection cavity, a coverplate is closed on the well body, and the cover plate is fixedly connected with the protection cover through a connecting rod; and a plurality of exhaust holes are formed in the cover plate, a worm and a rotating shaft are rotationally connected in the well body, and a linkage mechanism is arranged between the worm and the rotating shaft. According to the self-protection urban heat removal well, by utilizing the reaction characteristics of sodium bicarbonate and matching with the heat removal process, the protection cover can be automatically lifted or retracted under the action of a driving mechanism, the linkage mechanism and a lifting mechanism, so that the trouble of carrying the protection cover back and forth manually each time is avoided, and manpower is greatly saved; and power equipment is not needed in the driving process, and thus the cost is greatly saved.

Description

technical field [0001] The invention belongs to the field of public facilities, in particular to a chemical reaction-based self-protection urban heat exhaust well. Background technique [0002] Heating pipelines are often set up in cities to supply heat for people’s daily life and factory production. In order to avoid heating affecting the driving of vehicles, heating pipelines are generally installed in sewers. With the increase of urban population and factories The increase in production leads to an increase in the required heat supply, which in turn increases the pressure on the heating system. Therefore, it is often necessary to discharge hot gas through heat exhaust wells in cities to relieve the pressure on the heating system, often through heat exhaust wells Perform hot air discharge work. [0003] Heat exhaust wells are generally distributed beside the roads in cities. The hot air discharged from the heat exhaust wells can reach 60 degrees and above, which is easy t...

Problems solved by technology

[0003] Heat exhaust wells are generally distributed beside the roads in cities. The hot air discharged from the heat exhaust wells can reach 60 degrees and above, which is easy to burn pedestrians on the roadside. Therefore, protective covers are often installed around the heat exhaust wells to prevent the hot air from Spreading around can also give pedestrians a warning to avoid approaching. Due to the limited width of the road, in order to avoid affecting the road and being obstructed, it is often necessary to remove the protective cover when the heat removal operation is not performed. The whole process of setting the protective cover around the well body is extremely cumbersome and labor-intensive
