A change in the body temperature of the wearer can be observed immediately. When the body temperature of the wearer reaches or passes a warning value, a medical test can be performed as early as possible, while other people will be alerted, thus effectively blocking the spread of viruses and having a good decorative effect.
Provided is a non-excavation type reforming method of an oil tank, comprising: covering the inner surface of a tank body of the oil tank with a composite reinforcing layer by means of a bonding glue layer in the form of a release fabricated part; and covering one side, opposite to the tank body, of the composite reinforcing layer with an oil-gas barrier composite film layer by means of the bonding glue layer in the form of a fabricated part. In this way, the existing single-layer tanks can be reformed into double-layer tanks conveniently; the requirements for a higher whole strength of the oil tanks can be met; the barrier performances to oil and gas are improved; and the working procedures are simplified. According to the construction method where the materials and adhesives used are all prefabricated outside the tank, in-tank construction with zero solvents is completely realized, occupational injuries of construction staff caused by contact with conventional solvent-type materials for a long time can be avoided, and the construction safety and the environmental safety are improved.
A method for retrofitting an oil tank in a non-excavated way, comprising: applying a composite reinforcement layer (2), in the form of a prefabricated part, over the inner surface of the body (3) of the oil tank via an adhesive layer (1), the composite reinforcement layer (2) comprising a framework layer (21) and a glass fiber reinforcement layer (22) overlying the framework layer (21), the framework layer (21) comprising frameworks (211) and through cavities (212) being located among the frameworks and used for arranging oil and gas leakage detection elements; and applying an oil and gas barrier composite film layer (4), in the form of a prefabricated part, over a side of the composite reinforcement layer (2) opposite to the body (3) of the oil tank via an adhesive layer (1). Thus, an existing single-layer tank can be easily retrofitted to a double-layer tank with excellent performance; high requirements on integral strength of the oil tank are satisfied; the oil and gas barrier performance is enhanced; working procedures are simplified, the construction time is shortened, and the work efficiency is improved; in addition, occupational injury due to constructers contact with the traditional solvent type materials over a long period of time is avoided, and the construction safety is greatly improved.

ANTI-RIOT ROBOT USED FOR REFORMING OIL TANK AND OIL TANK REFORMING WORKING STATION
An anti-riot robot used for reforming an oil tank and an oil tank reforming working station. The anti-riot robot comprises a work program mode controller, an execution part, and a transmission part. The work program mode controller is used for presetting internal reforming of a current oil tank and is correspondingly provided with an anti-riot robot working path. The execution part is connected to the controller. The transmission part is connected to the controller and is used for, under of the control of the controller, for driving the execution part to implement internal reforming on the oil tank when passing through the working path.
A reforming method for an oil tank. comprises: preset a working program of a current anti-riot robot (1) that carries out inner reforming on a current oil tank (2), the working program corresponding to a working path of the current anti-riot robot; and under the guide of the working program, the current anti-riot robot carries out inner reforming on the oil tank by means of the working path. In this way, by using a method in which the anti-riot robots are used to replace human professionals to operate, a great deal of labor power can be saved, the working efficiency further can be greatly improved, the construction period is greatly shortened, and stop loss of a gas station is greatly reduced; meanwhile, by using the method in which the anti-riot robot workstation is used to replace a human to enter a tank to work, harm of occupational diseases to the humans can be effectively avoided, thereby radically avoiding personal diseases and pains, family burden and medical burden.
