Self-protection city heat removal well

Abstract

The invention belongs to the field of public facilities, and particularly relates to a self-protection city heat removal well which comprises a well body and a protection ground. The protection groundannularly surrounds the well body, a trigger cavity, an electric control cavity and a liquid storage cavity are formed in the well body, a permanent magnet rod is fixedly connected in the trigger cavity, and a heat conduction plate is embedded in the trigger cavity. The permanent magnet rod is sleeved with a magnetizing coil, the magnetizing coil is fixedly connected with the trigger cavity through a fixing rod, and a trigger switch matched with the permanent magnet rod is arranged in the trigger cavity. By means of the characteristic that the permanent magnet rod is heated and demagnetized,the trigger switch is closed, automatic rising of the coaming is achieved, the permanent magnet rod generates magnetism again through light changes, the photosensitive resistor and the magnetizing coil in cooperation at nightfall, the trigger switch is switched off again, the coaming can be automatically folded, the trouble of manual carrying is avoided, and the manpower loss is greatly reduced.

Description

technical field [0001] The invention belongs to the field of public facilities, in particular to a self-protecting urban heat exhaust well. Background technique [0002] With the development of the city, the surrounding factories and people's daily life often need heating pipes for heating. The heating pipes are generally installed in the sewer, which does not affect the driving of vehicles. Due to the increase in the heat required for urban production and life Therefore, it is often necessary to discharge hot gas through heat exhaust wells in cities to relieve the pressure on the heating system. In order to stagger the morning and evening peak commuting periods, hot air discharge operations are generally carried out from noon to afternoon. [0003] Heat exhaust wells are generally set up beside the road. Due to the high temperature of the discharged hot air, which can reach 60 degrees and above, it is easy to burn pedestrians on the roadside. Usually, there are shrouds aro...

Problems solved by technology

[0003] Heat exhaust wells are generally set up beside the road. Due to the high temperature of the discharged hot air, which can reach 60 degrees and above, it is easy to burn pedestrians on the roadside. Usually, there are shrouds around the heat exhaust well to prevent the hot air from flowing into the road. Spreading around can also give pedestrians a warning to avoid approaching. Due to the limited width of the road surface, there is a large flow of people after get off work in the evening, and there will be no heat removal work in the evening. Therefore, the hoarding needs to be removed in the evening to make room for the road. When the heat is discharged the next day, sanitation workers are required to place the hoarding around the well body. The whole process is extremely cumbersome and wastes manpower
