Abstract

The utility model discloses a kind of underground heat device for detecting leak point, comprises air lift pump, and described air lift pump is connected with the entrance point of geothermal tube; The endpiece of described geothermal tube is closed; Plastic film covering on the ground; Surrounding and the metope of film are bonded to one by double faced adhesive tape.The utility model has the advantages that: utilize the principle that the penetrating power of gas is stronger than liquid, after utilizing air lift pump that gas is pumped into geothermal tube, gas can flow out from leak source and be heaved by the film covered above, therefore, the position of leak source can be determined very soon, avoid and dismantle renovated ground on a large scale, time saving and energy saving province expense.

Description

A kind of underground heat device for detecting leak point
Technical field
The utility model relates to building field, is a kind of detection method and device of underground heat leak source specifically.
Background technology
Geothermal heating is the universal way in the north, but the drawback of geothermal heating is also apparent, and namely geothermal tube causes damage because of certain reason, leaks, and not only causes the damage in house downstairs, and is generally embedded in below ground due to geothermal tube, is difficult to determine leak source.For finding leak source, sometimes needing that entirety is carried out to renovated ground and destroying, causing very large loss; Present general fashion manually observes at the ceiling of lower floor's building, this kind of mode, general not too accurate, this is because certain water-proofing treatment has been carried out on ground, or is built with cement, that human eye is seen and not necessarily is leak source place, be likely that to depart from leak source far; Therefore, up to the present, good method is not still had to find the leak source of geothermal tube, the seepage that especially leak source is very little.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of underground heat leak source detection method and pick-up unit, and concrete technical scheme is as follows:
A kind of underground heat leak source detection method, arranges water blocking in the water outlet pipe part of underground heat, connects air lift pump at the water inlet pipe place of underground heat; The ground in the house leaked is laid the film of monoblock; The surrounding of described film by sticking double faced adhesive tape on the wall of surrounding; After gas is pumped into geothermal tube by air lift pump, the place of heaving of described film is leak source region.
For ensureing accurate measurement, also arrange bonding point between described film and ground, described bonding point spacing is 0.5-0.8 rice.The benefit of bonding point is set up to be: ground is divided into different regions by bonding point, does not have the region of leak source, and film can not be heaved, and has the region of leak source, and film can be heaved, and like this, just avoids gas and is heaved by whole film, cannot determine the drawback of leak source.
For solving leak source down, described gas is the density that density is less than air, as hydrogen, helium etc.
The invention also discloses the device realizing described method, comprise air lift pump, described air lift pump is connected with the entrance point of geothermal tube; The endpiece of described geothermal tube is closed; Plastic film covering on the ground; Surrounding and the metope of film are bonded to one by double faced adhesive tape.
Arrange bonding point between film and ground, described bonding point spacing is 0.5-0.8 rice.
The utility model has the advantages that: utilize the principle that the penetrating power of gas is stronger than liquid, after utilizing air lift pump that gas is pumped into geothermal tube, gas can flow out from leak source and be heaved by the film covered above, therefore, the position of leak source can be determined very soon, avoid and dismantle renovated ground on a large scale, time saving and energy saving province expense.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Illustrate the utility model below in conjunction with accompanying drawing, as shown in Figure 1, the utility model comprises air lift pump 1, and described air lift pump 1 is connected with the entrance point 2 of geothermal tube; The endpiece 3 of described geothermal tube is closed; Film 4 covers on the ground; Surrounding and the metope 6 of film 4 are bonded to one by double faced adhesive tape 7.After air lift pump 1 pumps air into geothermal tube, the place 5 of heaving of described film 4 is leak source region.
Utilize the penetrating power of the gas principle that strong and gas upwards flows than liquid, after utilizing air lift pump that gas is pumped into geothermal tube, gas can flow out from leak source and be heaved by the film covered above, therefore, the position of leak source can be determined very soon, avoid and dismantle renovated ground on a large scale, time saving and energy saving province expense.
