Abstract

An anti-freezing device of a drain pipe in an apartment house is provided to restrict freezing of a rubber drain pipe, and to prevent short circuit or electric shock by transferring striking particles through a fluid transfer passage for applying vibration to the rubber drain pipe at sub-zero temperature. A pump driving signal is output to a rely(96) in lowering outdoor temperature below the predetermined temperature, and current is streamed into a circulation pump(90) by exciting the relay. Particle transfer anti-freezing solution(80) is transferred from a storage tank(84) to a fluid transfer passage between a rubber drain pipe and outer semicircular pipes(40,50) through pipes(200,202) and a supply pipe(62) in driving the circulation pump. Striking particles(82) are bumped into a soft annular projection of the rubber drain pipe to transmit kinetic energy to the rubber drain pipe, and vibration is transmitted to the rubber drain pipe to prevent freezing. The particle transfer anti-freezing solution is recycled through a discharge pipe(72) to the storage tank.

In general, drain pipes are installed in apartments such as apartments are installed through the slab of each floor balcony, it is to drain the waste discharged through the balcony.

Such a conventional drainage pipe for a multi-family house had a problem in that when the external temperature drops to below zero in a cold weather, moisture remaining inside the drainage pipe freezes and freezes.

In order to prevent such freezing, conventionally, a flexible linear heater is installed inside the drain pipe to prevent the drain pipe from freezing by flowing a drive current to the linear heater to generate heat when the outside temperature drops below zero, but the linear heater is discharged through the drain pipe. There was a high possibility of disconnection because the structure was always in contact with the dirt. If the insulation covering the linear heater was peeled off, there was a risk of electric leakage or electric shock.

In addition, since the linear heater is flexible and does not have any centering means, it is located at the center of the drain pipe so that the temperature is not evenly distributed and it is biased on one side, causing the drain pipe to undergo thermal deformation. Therefore, it was difficult to apply the heater.

The particle transfer antifreeze 80 is used to facilitate the transfer of the striking particle 82 by using a high viscosity, the striking particle 82 is made of, for example, a steel ball of 1mm ~ 2mm diameter made of stainless steel with excellent corrosion resistance Can be.

In addition, the circuit for driving the circulation pump 90 includes a temperature sensor 92 for periodically detecting the outside temperature; When it is determined that the outside air temperature has fallen below the set temperature by comparing the outside temperature detected by the temperature sensor 92 connected to the input terminal, the pump driving signal for driving the circulation pump 90 is output, and the outside temperature is A controller 94 for outputting a pump stop signal when it is determined that the set temperature is exceeded; The relay 96 is connected to the output terminal of the controller 94 and drives the circulation pump 90 by the pump drive signal output from the controller 94.

In addition, the hole formed in the center of the upper hollow cap 49 and the lower hollow cap 59 is a groove for fitting the O-ring (100, 102) in close contact with the outer peripheral surface of the upper connecting pipe 60 and the lower connecting pipe 70 (104) and (106), and the circulation pump 90 and the supply pipe 62 and the circulation pump 90 and the discharge pipe 72 is connected through the pipes 200 and 202.

Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.

When the external temperature drops below zero, as shown in FIGS. 1 to 7, dirt drained through the rubber drainage pipe 30 freezes inside the rubber drainage pipe 30, and there is a fear of freezing. In the freezing prevention operation of the present invention, the outside air temperature detected from the temperature sensor 92 is periodically compared with the set temperature by the controller 94. When the result of the comparison determines that the outside air temperature has fallen below the set temperature, the controller 94 The pump driving signal is output to the relay 96 from the output stage of the circuit, and the relay 96 connected thereto is excited to close the relay contacts so that the driving current flows to the circulation pump 90.

At this time, while the circulation pump 90 is driven, the particle transfer antifreeze liquid 80 stored in the storage tank 84 is passed through the rubber drain pipe 30 and the outer semicircular pipe 40 through the pipes 200 and 202 and the supply pipe 62. It is pressurized by the fluid conveyance path P formed between (50).

In this process, the small blown particles 82 mixed with the particle transfer antifreeze 80 are also transferred along the particle transfer antifreeze 80, and the particle transfer antifreeze 80 is a zigzag-shaped fluid transfer path P. The kinetic energy is transferred to the rubber drainage pipe 30 while hitting the blow particles 82 mixed in the particle transport antifreeze 80 in the course of passing through the soft ring-shaped protrusion 34 formed in the rubber drainage pipe 30.

At this time, the rubber drain pipe 30 is caused to vibrate by hitting particles 82 hitting the soft annular projection 34, the vibration is transmitted to the entire rubber drain pipe 30 is frozen inside the rubber drain pipe (30) It is to prevent the action.

That is, by making a stable state, which is one of conditions for growing into ice with a large amount of moisture, to make the state unstable, it suppresses the growth of ice crystals in the rubber drainage pipe 30, and grows only in the form of small grains even when freezing occurs during a cold season. As a result, growth and removal of the rubber drainage pipe 30 by vibration prevents freezing by freezing.

In addition, vibration is continuously generated while the particle transfer antifreeze 80 passes through the fluid transfer passage P, and the particle transfer antifreeze 80 passed through the fluid transfer passage P is disposed at the lower end of the rubber drainage pipe 30. Return to the storage tank 84 through the discharge pipe 72 formed on the side of the lower connection pipe 70 is recycled.

On the other hand, if it is determined that the outside temperature detected by the temperature sensor 92 exceeds the set temperature, the contact point of the relay 96 is opened while the pump stop signal is output from the output terminal of the controller 94 to the relay 96, The current flowing to the circulation pump 90 is cut off so that the circulation pump 90 is stopped.

Since the present invention as described above is configured to cause vibration in the rubber drainage pipe while the external air temperature drops to below zero, countless hitting particles are pushed into the fluid transfer path between the rubber drainage pipe and the outer semicircular pipe by the particle transport antifreeze. There is an effect that can prevent freezing of the rubber drainage pipe by vibration, and in particular, since it is configured to suppress the growth of ice in the rubber drainage pipe by physical vibration rather than the heat generation as before, there is a fear of electric leakage or electric shock. There is no effect at all and becomes safe.

Furthermore, since the present invention is configured to prevent freezing by vibration as opposed to preventing freezing by heat as in the past, it is also very easy to apply to a synthetic resin drain pipe that is susceptible to heat.
