The utility model has the characteristics of simple structure, convenient to use.
Description
Technical Field
The utility model relates to a plastics drain pipe technical field, in particular to outdoor plastics drain pipe leak hunting device.
Background
Outdoor engineering often adopts plastics system HDPE pipe direct-burried to lay for reducing the cost, and because the pipeline buries deeply underground, overhauls comparatively troublesome, if the pipeline peripheral condition that appears sinking hardly judges whether pipeline damage causes or other reasons cause, if whether sinking that causes for other reasons leads to the pipeline to take place to damage also hardly judges, the known pipeline damage inspection in existing market is examined for using the robot to take camera device to inspect, and the cost is great.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model aims to provide an outdoor plastic drain pipe leakage detection device, which has the characteristics of simple structure and convenient use.
In order to realize the purpose, the utility model discloses a technical scheme is:
a leakage detection device for an outdoor plastic drain pipe comprises a second angle valve 5 arranged on a detection pipe, wherein a vertical liquid level meter 3 is arranged on the upper surface of the detection pipe, and the liquid level meter 3 is communicated with the detection pipe through a first angle valve 4;
the two ends of the detection tube are provided with rubber air bags 1 capable of injecting water.
The surface of the water-injection rubber air bag 1 is provided with an inflation inlet 2.
The detection tube and the water-injection rubber air bag 1 are formed in one step.
The utility model has the advantages that:
the device is simple to manufacture, low in material cost, convenient to manufacture, low in processing cost which is about 600 yuan, far lower than the cost of thousands of pieces of robot detection instrument, convenient for water source taking, convenient to operate, stable in working performance and capable of embodying the practicability through experiments. Can be put into the detection of outdoor direct-buried drainage pipelines.
Because the detection pipe is arranged in the water injection air bag, the air tightness of the whole device can be influenced by connecting the detection pipe in a field in an adhesive mode, the detection pipe needs to be formed at one time during production, and the phenomenon that the detection result is influenced by water leakage of the device due to inaccurate connection during later use is avoided.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a working principle diagram of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1: a leakage detection device for an outdoor plastic drain pipe comprises a second angle valve 5 communicated with a detection pipe, wherein a liquid level meter 3 is arranged on the upper surface of the detection pipe, and the liquid level meter 3 is communicated with the detection pipe through a first angle valve 4;
the two ends of the detection tube are provided with water-injection rubber air bags 1, and the surfaces of the water-injection rubber air bags 1 are provided with inflation ports 2.
The detection tube and the water-injection rubber air bag 1 are formed in one step.
Because the detection pipe is arranged inside the water-injection rubber air bag 1 and is connected in a field in an adhesive mode, the air tightness of the whole device can be influenced, so that the detection pipe needs to be formed at one time during production, and the phenomenon that the detection result is influenced due to water leakage of the device caused by inaccurate connection during later use is avoided.
The utility model discloses a theory of operation:
as shown in fig. 2: by utilizing the equal liquid level principle, the water level in the pipeline is the same as the water level of the liquid level meter 3, if the pipeline leaks water, the water level of the liquid level meter 3 descends, and if the pipeline does not leak water, the water level of the liquid level meter 3 is unchanged. Therefore, whether the pipeline leaks water or not is judged, and whether the damage condition exists or not is judged.
The using method comprises the following steps:
firstly, inflating, plugging and reinforcing two ends of a detection pipe section by using the device and a common air bag respectively to prevent overlarge water quantity from rushing out of the pipeline, opening a liquid level meter 3 and a second angle valve 5 on a water injection pipe, injecting water into the detection pipe section through the water injection pipe until the liquid level meter 3 observes that the water level exceeds the upper level of the pipeline, stopping injecting water, closing the second angle valve 5 of the water injection pipe, observing the water level change condition of the liquid level meter 3, and if the water level is reduced, leaking the pipeline and damaging the pipeline; if the water level is not changed, the water leakage of the pipeline is avoided, and the pipeline is not damaged.
