Embodiment
Below in conjunction with accompanying drawing, be described in more detail with other technical characteristics and advantage the present invention is above-mentioned.
The present invention is a kind of detection device and detecting method thereof, described detection device 1 is to be installed in the pipeline to be measured 2 of underground utility, please consult Fig. 1-shown in Figure 3 respectively, described detection device 1 is made up of an air wheel body 10, another air wheel body 20 and a connection part 30 respectively; Wherein said air wheel body 10 is in order to fill the inside of described pipeline to be measured 2, and be to be the axle center 11 of I font skeleton and first end plate 12, second end plate 13 of two ends thereof by a section, be coated with the airtight hollow cylinder that an elasticity body 14 is formed, and be respectively equipped with one first tracheae 121 and be exposed on described first end plate 12 outside in described airtight hollow cylinder, extending, with one second tracheae 122 in described airtight hollow cylinder, extend outer being exposed on described first end plate 12, second end plate 13 respectively.
Described another air wheel body 20 also is in order to fill the inside of described pipeline to be measured 2, and also be to be another axle center 21 of I font skeleton and another first end plate 22, another second end plate 23 of two ends thereof by a section, be coated with another airtight hollow cylinder that another elasticity body 24 is formed, and be provided with one the 3rd tracheae 221 in described another airtight hollow cylinder, extend in the described airtight hollow cylinder of described air wheel body 10.
In the present invention, second end plate 13 of described air wheel body 10 and another first end plate 22 of described another air wheel body 20 be that the two ends by described connection part 30 are connected and fixed respectively, and its length are an intended distance (4 meters).
Aforementioned described first tracheae 121 be in order to one superheated steam pour in the described airtight hollow cylinder of described air wheel body 10; And described the 3rd tracheae 221 also is in order to in the described airtight hollow cylinder of described superheated steam by described air wheel body 10, imports in described another airtight hollow cylinder of described another air wheel body 20; Again, described second tracheae 122 is in order to described superheated steam is poured into 20 formed sealed air chamber 101 (as shown in Figure 4) of described air wheel body 10 and described another air wheel body.
The distance of aforementioned described air wheel body 10 and described another 20 formed sealed air chamber 101 of air wheel body is the scope that described detection device 1 desire detects described pipeline to be measured 2.
On first end plate 12 of aforementioned described air wheel body 10, further can connect at least one another connection part 31, described detection device 1 can be pushed away described sealed air chamber 101 formed distances by described another connection part 31, to carry out the detection of next section pipeline 2 to be measured, whole section pipeline detection of described pipeline to be measured 2 also finished in segmentation smoothly so successively, finds out its damaged part and repairs.
Aforementioned described connection part 30 is respectively a body of rod with described another connection part 31.
By above-mentioned member, see also shown in Figure 6ly, when detection device 1 of the present invention detects at the pipeline to be measured 2 that carries out described underground utility, will carry out according to following detecting method:
Step 1: at first, described detection device 1 is mounted in the described pipeline to be measured 2 (as shown in Figure 3);
Step 2: first tracheae 121 and described the 3rd tracheae 221 that passes through described detection device 1 again, described superheated steam (as: 1.5 kilograms/square centimeter) is poured in the air wheel body 10 and described another air wheel body 20 of described detection device 1, make described air wheel body 10 elasticity body 14 outward and described another air wheel body 20 another elasticity body 24 expansion evaginations outward, and fit tightly (as shown in Figure 4) with described pipeline 2 inwalls to be measured, monitor the air pressure in described air wheel body 10 and described another air wheel body 20 again;
Step 3: at this moment, the sealed air chamber 101 (as shown in Figure 4) that described air wheel body 10 and 20 of described another air wheel bodys can form, second tracheae 122 by described detection device 1 is forced into another superheated steam (as: 1 kilogram/square centimeter) with described superheated steam (as: 1.5 kilograms/square centimeter) again, pour into described sealed air chamber 101 again, and monitor the air pressure of described sealed air chamber 101, after treating a scheduled time (as: one minute), the air pressure of sealed air chamber 101 does not as described descend, represent that promptly the pipeline seal in the described section sealed air chamber 101 formed distances (as: 4 meters) is good, there is no and reveal the situation generation;
Step 4: after, release the described superheated steam in described air wheel body 10, described another air wheel body 20 and the described sealed air chamber 101 more in regular turn respectively, utilize at least one another connection part 31 to be connected to first end plate 12 of described air wheel body 10 again, by described another connection part 31 described detection device 1 is pushed away described sealed air chamber 101 formed distances, and repeat above-mentioned steps successively segmentation whole section pipeline finishing described pipeline to be measured 2 smoothly detect (as shown in Figure 5), find out its damaged part and repair.
By the above as can be known, the different prior art key of the present invention is:
One, because detection device 1 of the present invention is to utilize the mode of monitoring air pressure to detect the integrity of described pipeline to be measured 2 with segmentation, so after measuring described pipeline to be measured 2 damaged parts, can excavate its damaged part accurately, and excavate and repair with regard to described damaged part, can't be after underground utility complete earthing in order to replace existing detection device, definitely find out the damaged part of described underground utility, and cause whole section property excavation consuming time, and the shortcomings such as aging etching problem that detect the described several years underground utility that completed can only be provided, so the present invention has novelty and practicability.
Two, because detection device 1 of the present invention is respectively described air wheel body 10 to be inflated with described another air wheel body 20, treat described air wheel body 10, after the inwall of 20 outside and described pipeline to be measured 2 fits tightly, with described another superheated steam pour into described air wheel body 10, in 20 formed described sealed air chamber 101, to test the tightness of described pipeline to be measured 2, and then sectional detects the integrity of described pipeline to be measured 2, find out the damaged part of each segmented pipeline, and excavate and repair with regard to damaged part, exempt whole section property excavation consuming time, therefore the present invention has progressive, all has using value in related industry (as: underground pipeline project industry etc.) simultaneously.
The above only is preferred embodiment of the present invention, only is illustrative for the purpose of the present invention, and nonrestrictive.Those skilled in the art is understood, and can carry out many changes to it in the spirit and scope that claim of the present invention limited, revise, even equivalence, but all will fall within the scope of protection of the present invention.
