Description

Technical Field

[0001] The utility model relates to the technical field of leakage detection, in particular to a water conservancy foundation leakage detection and positioning device. Background Art

[0002] In the process of water conservancy construction, foundation leakage detection is an important step. Leakage detection is used to determine the degree of water seepage in the foundation. At present, the drilling and water injection method is usually used for foundation leakage detection. The method is to first drill a hole of a certain depth in the foundation through a drilling mechanism, and then inject water of a certain pressure into the hole, maintain the pressure for a period of time, and then observe the remaining water content in the hole to infer the leakage of the foundation. When detecting foundation leakage, when drilling a hole in the foundation through a drilling mechanism, a positioning mechanism is required to ensure the stability of the drilling mechanism during drilling. In the prior art, there are many kinds of water conservancy project foundation leakage detection and positioning devices with patent application numbers 202120669224.7, 202121212367.1 and 202121715717.6. When lowering the detection mechanism or drilling mechanism, the pressure rod directly drives the detection mechanism or drilling mechanism to lower through the hydraulic cylinder, and the workers can only rely on their experience to judge the lowering distance of the drilling mechanism. This may easily lead to the drilling depth of the hole drilled by the drilling mechanism being too deep or too shallow during leakage detection, thereby affecting the accuracy of leakage detection. It is inconvenient to use, and a positioning device that can conveniently judge the drilling depth of the drilling mechanism is needed. Utility Model Content

The pointer 4 points to the scale 5, and the scale 5 is fixedly installed on the mobile vehicle 1; the external drilling mechanism 6 is fixedly installed at the lower end of the lifting plate 2. When performing foundation leakage detection in water conservancy projects, the drilling mechanism 6 must first be used to locate the drilling hole on the foundation. When drilling, the mobile vehicle 1 is first moved to the position where the drilling hole is required, and then the lifting plate 2 is lowered by the lifting mechanism. The lifting plate 2 drives the drilling mechanism 6 to descend to the drilling mechanism 6. The drill bit contacts the foundation, and then observes and records the scale value pointed to by the pointer 4 on the scale 5, and then continues to make the lifting plate 2 drive the drilling mechanism 6 to descend.
