In particular, when the temperature around the indoor fire hydrant in winter falls below zero, the fire water contained in the fluid supply pipe and the angle valve freezes and expands. there was.

On the other hand, in the prior art, in order to solve the above problems, a hot wire is installed in the fluid supply pipe.

However, since the fluid supply pipe is buried in the wall of the building, it is necessary to install a heating wire in the fluid supply pipe before embedding the fluid supply pipe in the wall of the building, thereby delaying the construction. In addition, in the case of the heating wire, since the operator has to install it one by one along the outer surface of the fluid supply pipe in all sections that require heat preservation, the work is difficult, a long time is required to complete the work, and there is a problem in that a lot of costs are generated.

In addition, in the prior art, as the heating wire is buried in the wall of the building together with the fluid supply pipe, it is impossible to check the state of the heating wire, and even if there is an abnormality in the heating wire, the wall in which the heating wire is embedded and the insulating material surrounding the heating wire must be removed. There was a problem.

In addition, since the heating wire is made of a synthetic resin material such as plastic, tracking phenomenon or deformation of the external shape occurs due to insulation breakdown due to aging during long-term use, which causes a fire due to a short circuit. there was.

In addition, according to the embodiment of the present invention, since the freeze protection device 100 is made of a metallic material, durability is strengthened to prevent tracking phenomenon and deformation of appearance due to insulation breakdown due to aging, and to prevent fire due to short circuit. occurrence can be prevented.

In addition, according to the embodiment of the present invention, since the position of the freeze protection device 100 can be adjusted in a state where it is coupled to the pipe P, it is easy to install and remove it in the indoor fire fighting box F with a narrow internal space. It is possible, and by minimizing interference with other substrates except for the pipe P, it is possible to prevent the heat of the freeze protection device 100 from being directly transmitted to other substrates.

In addition, according to an embodiment of the present invention, the heat generating unit 110 that radiates heat and the heat transfer unit 120 that is coupled to the pipe P to transfer the heat of the heat generating unit 110 have a structure that is detachable from each other. Therefore, it is possible to replace each part, so maintenance is easy, and through this, the service life of the product can be increased.

In addition, according to the embodiment of the present invention, since it is possible to directly and intuitively check the driving state and the power supply state of the freeze protection device 100 through the control device 200 in the field, quick inspection and maintenance can be performed.
