Abstract

PURPOSE: A freeze protection structure for a pipe of an exterior wall of a building is provided to prevent damage to a pipe caused by a water freeze without draining the water inside the pipe in advance because a heating device is automatically operated according to a temperature sensor below zero temperature. CONSTITUTION: A freeze protection structure for a pipe of an exterior wall of a building comprises a heating coil spring(30), upper and lower heating power lines(11,21), and a heat-insulating bellows tube(40). The upper part of the heating coil spring is fixed to an upper current applying fixed ring(10) and the lower part of the heating coil spring is fixed to a lower current applying movable ring(20). When the heating coil spring is downwardly extended by elasticity, heat is radiated by the upper and lower heating power lines so that a freezing of water inside a pipe is prevented. The heat-insulating bellows tube covers the heating coil spring in outside and protects the heating coil spring by being extended as long as an extended length of the heating coil spring. The water inside the pipe is not frozen due to the heating coil spring covering an outer periphery of the pipe even in cold weather.

The upper energizing stationary ring 10 is a circular ring member whose one side is fastened and fixed to the upper end of the pipe 60 by means of bolts 14 and a nut 14a and an upper heating power supply line 11 And a lower end protruding portion 12 protruding downward from the lower end face of the lower end face and having an energizing terminal hole 12a through which the upper heating power supply line 11 is energized to flow, And a lower ring groove 13 is formed at the periphery.

The lower energizing moving ring 20 is a circular ring body fixed on one side by a bolt 26 and a nut 26a so as to be slidably coupled to a lower end of the pipe 60, The upper heating power supply line 21 is inserted into the upper heating power supply line 21 and the upper end of the upper heating power supply line 21 is protruded upward and connected to the lower heating power supply line 21 to have a power supply terminal hole 22a, And a plurality of ball bearings 23 are mounted on the inner circumference of the outer circumferential surface of the outer circumferential surface of the outer circumferential surface of the outer circumferential surface (60) from the outer periphery to the upper and lower portions.

The heating coil spring 30 is wound between the upper energizing holding ring 10 and the lower energizing moving ring 20 so as to be spaced apart from the outer periphery of the pipe 60 and has elasticity, The upper end of which is inserted into the energizing terminal hole 12a of the energizing lower end protruding portion 12 of the upper energizing stationary ring 10 and energized and the tip thereof protruding outward is inserted into a nut The upper end bolt portion 31 fastened and fixed by the lower end energizing moving ring 20 is inserted into the energizing terminal hole 22a of the energizing upper end protruding portion 22 and energized, And a lower end bolt portion 32 is fastened and fixed by the nut 32a so that heat is generated during energization to prevent water in the pipe 60 from freezing.

The upper and lower end portions of the heat insulating corrugated pipe 40 are separated from the heating coil spring 30 to protect the heating coil spring 30 from the lower end ring groove 13 of the upper energizing retaining ring 10 42 and the upper ring grooves 24 of the lower energizing moving ring 20 are each provided with the interference tightening rings 41 and 42 which are fixedly held by the interference projections 41a and 42a and the interference fit grooves 41b and 42b, Respectively.

The lower fixed control ring 50 is a circular ring body having one side fixed to the lower end of the pipe 60 below the lower energizing moving ring 20 by a bolt 56 and a nut 56a, A motor fixing hole 52 in which the other side of the drive motor 53 having the drive shaft 53a is screwed into the motor fixing hole 52 is formed at one side of the outer periphery of the motor 51, One end of the winding wire 54b wound around the winding groove 54a is fixed to the hooking portion 25 of the lower end moving and moving ring 20 at one side of the drive shaft 53a, And the driving shaft 53a of the driving motor 53 is driven in the normal rotation so that the winding wire 54b is connected to the power supply line 51. In this case, Is wound around the winding groove (54a) to move the lower energizing moving ring (20) to the lower side of the pipe (60) When the heating coil spring 30 is heated and the temperature of the heating coil spring 30 is not sensed and the upper and lower heating power source lines 11 and 21 are energized while the heating coil spring 30 is stretched in the lower direction, A temperature sensing sensor 55 for driving the coil spring 53a in the reverse direction to unscrew the winding wire 54b from the winding groove 54a of the winding reel 54 and return it to the restoring force by the elasticity of the heating coil spring 30, Respectively.

In the present invention, when the temperature sensing sensor 55 mounted on the inner surface of the lower fixed control ring 50 fixed to the lower end of the pipe 60 senses the temperature of the sub-pipe, it is connected to a control unit The control unit recognizes the rotation of the driving motor 53 and rotates the drive shaft 53a of the driving motor 53 forward to wind the winding wire 54b around the winding groove 54a of the winding reel 54, And slowly pulled downward on the pipe 60 to slide.

At this time, the heating coil spring 30 connected to the lower end energizing and moving ring 20 is also elastically expanded downward, so that the entire surface of the pipe 60 is covered with the heating coil spring 30. At the same time, the upper and lower heating power supply lines 11 and 21 are energized to generate heat of the heating coil spring 30.

The controller may be configured separately from the temperature sensor 55. However, since it is preferable that the controller is integrally formed on one side of the temperature sensor 55 as described above, the temperature sensor 55 has a function of the controller .

That is, the heating coil spring 30 whose upper end is fixed to the upper energizing retaining ring 10 and whose lower end is fixed to the lower energizing moving ring 20 is stretched and expanded downward by elasticity so that the upper and lower heating power source wires 11 and 21 to dissipate heat to prevent the water inside the pipe 60 from freezing.

At the same time, the heat-insulating corrugated pipe 40, which is a foil-like shape for wrapping the heating coil spring 30 from the outside, is also expanded and contracted while expanding and contracting the heating coil spring 30.

In this state, the water inside the pipe 60 can keep the state of not being frozen by the heating coil spring 30 that generates heat while surrounding the outer periphery of the pipe 60 even under a severe cold temperature.

In this state, when the temperature sensor 55 of the lower fixed control ring 50 senses the temperature of the image, the controller senses the temperature of the image and transmits the detected temperature to the control unit. The control unit receives the rotation of the drive shaft 53a of the drive motor 53, And cut off the power supply to the upper and lower heating power supply lines 11 and 21.

At this time, when the driving shaft 53a of the driving motor 53 is rotated in the reverse direction to unwind the winding wire 54b wound around the guiding groove 54a of the winding reel 54, the winding wire 54b pulls the pipe 60, The lower end electrifying moving ring 20 pulled downward is slid upward from the pipe 60 due to the resilience of the heating coil spring 30 due to the externally pulling down force of the heating coil spring 30, .
