In deep-well freezed, the fracture of freezing pipe happened occasionally, and fracture of freezing pipe salt solution will take place leaks; Cause frost wall directly to receive the salt water erosion, frost wall intensity reduces, and stress balance state is originally further destroyed; The a barrage of disconnected event of running affairs will further take place, thereby cause economic loss in the freezing pipe discontinuity; Safety to frozen construction threatens simultaneously, therefore in the shortest time, finds disconnected pipe, takes effective remedial measure most important.
The warning device of existing technology is as shown in Figure 1, can be that steel or other proportion are greater than 1.2g/cm in inner its material of magnetic ball 40 of placing of conical steel pipe 20
2Magnetic material, the top of this magnetic ball 40 is provided with snubber 50, is used for limiting the moving range of magnetic ball.Place inductor 30 in the outside of conical steel pipe 20, be used for the position of induced magnetism ball 40 in conical steel pipe 20.During proper functioning, water supply connector 10 place's pressure are greater than water output connector 60 place's pressure, and magnetic ball 40 is by jack-up, and the saline flow direction is shown in arrow among Fig. 1.During fracture of freezing pipe, magnetic ball is fallen its lowermost position and is blocked water supply connector 10, thereby prevents salt solution leakage inductor warning simultaneously.But it is not prompt enough that this device is reported to the police, and cost is high, and main device is arranged on steel duct, the difficult observation.
The model utility content
Warning device when the utility model provides a kind of fracture of freezing pipe, purpose be solve device of the prior art report to the police untimely, cost is high and be difficult for the defective of finder internal structure.
In order to achieve the above object, said device comprises U-shaped pipe, electrode, lead, glycerine and alarm; Wherein, Glycerine is housed in the U-shaped pipe curved portion; Two electrodes are installed on the last lower wall in the U-shaped pipe bottom tube respectively and are immersed in the said glycerine, and first end of two leads is connected on the electrode through two holes of U-shaped pipe bottom respectively, and two second ends are connected on the alarm; Wherein two of the U-shaped pipe ports are connected on salt solution liquid inlet pipe and the liquid return pipe.
As preferred embodiment, said device also comprises sealer; The said hole that is used to pass lead is sealed with sealer, and the thickness of sealer is identical with the U-shaped pipe thickness.
As preferred embodiment, around the said hole of U-shaped pipe outer wall, coat sealer, and its thickness is greater than 5 times of the U-shaped pipe thickness.
As preferred embodiment, said sealer is an epoxy resin sealant.
As preferred embodiment, the material of said U-shaped pipe is transparent withstand voltage glass or withstand voltage and nonconducting macromolecular material.
As preferred embodiment, said alarm is the warning device with current work.
As preferred embodiment, said alarm is a Han Rong TFB rotary caution light.
Can find out that from technique scheme when fracture of freezing pipe, the pressure at U-shaped pipe two ends is no longer identical, glycerine leaves U-shaped pipe bottom is immersed in the salt solution electrode, forms electric circuit and causes that alarm in time reports to the police.The device of the utility model is reported to the police timely, simple in structure, easy to make and is easy to and observes, and has solved therefore that the warning of warning device is untimely in the existing technology, cost is high and has been difficult for the problem of finder internal structure.

Embodiment
Following with reference to accompanying drawing, the warning device of the specific embodiment that develops simultaneously during to the fracture of freezing pipe of the utility model carries out detailed explanation.
Device among the embodiment of the utility model comprises U-shaped pipe 3, glycerine 4, electrode 5, lead 6, epoxy resin sealant 7 and alarm 8.Wherein, epoxy resin sealant 7 comprises epoxy resin sealant 71 and epoxy resin sealant 72.
U-shaped pipe 3 is transparent withstand voltage glass or withstand voltage and nonconducting macromolecular material; As shown in Figure 2; Lower wall is installed an electrode 5 respectively in U-shaped pipe bottom tube; These two electrodes 5 are connected with first end of two leads 6 respectively, and second end of two leads 6 stretches out with the both positive and negative polarity of alarm 8 through two holes 34 on the U-shaped pipe bottom respectively simultaneously and is connected respectively.The alarm 8 here can adopt the warning device with current work, like Han Rong TFB rotary caution light.Curved portion at the U-shaped pipe is equipped with glycerine 4, and electrode 5 is immersed in the glycerine 4.
Wherein, as shown in Figure 3, hole 34 is by epoxy resin sealant 71 sealings, and the thickness of sealer is the wall thickness L2 of U-shaped pipe 3 here, also scribbles epoxy resin sealant 72 around the hole 34 on the outer wall of U-shaped pipe 3, and its thickness is L1.In order better glycerine 4 to be sealed in the U-shaped pipe 3, get L1＞5L2 usually.
The Placement of said device and freezing pipe 300 is as shown in Figure 4; Wherein U-shaped pipe 3 is connected with liquid return pipe 200 with the liquid inlet pipe 100 of freezing pipe 300 respectively with 32 through its interface 31; In the U-shaped pipe 3 glycerine 4 above be salt solution 400 from freezing pipe 300, notice during connection guaranteeing that the pressure at port 31 and 32 places equates.
