The embodiment of the utility model provides a water measuring device while drilling 100 is proposed. As shown in FIG. 1, the water measurement while drilling device 100 comprises a sleeve 1, a connector 2, a dynamic seal assembly, a flow guide pipe 3 and a flow meter 4. Wherein the sleeve 1 is intended to be arranged at the open end of a borehole. And, the drill rod 200 extends into the inner cavity of the sleeve 1 and is sleeved with the sleeve 1 in a spaced manner. During drilling of the drill pipe 200, after the water layer is penetrated, the water gushes out through the annulus between the drill pipe 200 and the sleeve 1. The connector 2 is disposed at the upper end of the sleeve 1 (it should be noted that, here, the connector is consistent with the left end in fig. 1, and is only for convenience of description and does not constitute a limitation on the use of the water measuring while drilling device 100, that is, depending on the application of the water measuring while drilling device 100, the connector 2 may be at the lower end or the obliquely lower end, or at the upper end or the obliquely upper end of the geodetic coordinate system of the sleeve 1), and is itself cylindrical. In addition, the drill rod 200 also passes through the inner cavity of the connector 2 at intervals. The annulus between the coupling head 2 and the drill pipe 200 receives a water flush through the casing 1. The dynamic seal assembly is arranged between the connector 2 and the drill rod 200 to seal, and water is prevented from flowing out from the upper end of the connector 2. A receiving annulus 5 is formed between the coupling head 2 and the drill pipe 200 by the dynamic seal assembly. The draft tube 3 is used for communicating the receiving annulus 5 with the outside to convey water entering the receiving annulus 5 out (the line with an arrow in fig. 1 indicates the flow direction of the gushing water). The flow device 4 is arranged at the downstream of the draft tube 3 and used for calculating the water quantity so as to realize accurate measurement.
According to the water measuring while drilling device 100, water gushing can be collected during drilling so as to perform real-time continuous measurement. In addition, the water measurement while drilling device 100 can effectively avoid water leakage, thereby ensuring the completeness of water collection and the precision of measurement. Therefore, the water measuring device 100 while drilling can provide data basis for exposing concrete positions and water inflow amount of water conducting channels such as aquifer structure cracks and faults and the like and controlling water damage for drilling.
In one embodiment, the dynamic seal assembly has a water seal retainer 61 and a seal ring 62. Wherein, the water seal retainer ring 61 is arranged between the connector 2 and the drill rod 200. Sealing ring 62 is also located at coupling head 2 and drill pipe 200 and at the upper end of water seal retainer 61. The dynamic seal assembly is simple in structure, sealing can be achieved, and the drill rod 200 can be guaranteed not to affect movement relative to the connector 2. Preferably, in order to ensure a good sealing effect, the sealing ring 62 may be plural, as shown in fig. 2. The plurality of seal rings 62 are engaged in a concave-convex manner at the abutment surface. Specifically, a projecting ring 63 having a triangular axial cross section is provided on an abutting surface of one 62 of the adjacent two seal rings 62. Meanwhile, a groove 64 having a triangular axial cross section is provided on the abutment surface of the other seal ring 62. The protruding ring 63 can be inserted into the groove 64 and form a male-female fit when the sealing ring 62 is connected close together. The arrangement mode improves the sealing effect, avoids the leakage of gushing water and further improves the measurement precision.
Specifically, a crimping sleeve 7 is provided at the upper end of the connection head 2. A first step surface 71 facing downward is provided on the inner wall of the crimp sleeve 7. Meanwhile, an upward facing second step surface 21 is provided on the inner wall of the connection head 2. Wherein the dynamic seal assembly is disposed between the first step surface 71 and the second step surface 21. That is to say, the first step surface 71 and the second step surface 21 axially limit the position of the dynamic seal assembly, and the installation is ensured.
For example, the crimp sleeve 7 is screwed to the connection head 2. The connection mode is simple and easy to realize. Meanwhile, the threaded connection mode enables the axial distance between the first step surface 71 and the second step surface 21 to be easily adjusted, so that the dynamic seal assembly is properly pushed up, and the sealing effect is further ensured. Even if the dynamic seal assembly has abrasion, the compression degree of the dynamic seal assembly can be adjusted by adjusting the crimping sleeve 7 so as to adjust the sealing effect. The arrangement can conveniently adjust the sealing effect of the dynamic sealing assembly, greatly reduce the consumption of water inrush and reduce the calculation and measurement error of water inrush amount. In addition, a handle 72 is protrudingly provided on the outer wall of the crimping sleeve 7 for screwing, which facilitates the operation.
A guide tube 22 is provided on the wall of the connector 2, the guide tube 22 communicating with the receiving annulus 5. The guide tube 22 is used for connecting the guide tube 3, which facilitates the installation of the guide tube 3. And, the sleeve 1 is connected with the connector 2 through a flange. The connection relation is simple, and the disassembly and the assembly are both convenient.
The draft tube 3 is provided with a U-shaped flow passage 31. Wherein the flow meter 4 is provided on a lateral portion of the manifold valve 31. This arrangement provides for a lateral portion at the lower end to ensure that water passing through the lateral portion of the flow tube 31 is relatively full, thereby ensuring the accuracy of the measurement of the flow meter 4. In addition, the flow meter 4 may be flange-mounted on the flow pipe 31 for easy removal and installation.
A sedimentation tank 8 communicated with the draft tube 3 is arranged at the upstream end of the flowmeter 4. The water from the receiving annulus 5 is first directed to a settling tank 8. Then, it is introduced to the flow rate meter 4 through the lateral portion of the flow tube 31. By providing a sedimentation basin 8 in which sand is sedimented, the downstream flow device 4 is protected. A slag discharge port 81 for discharging slag is arranged on the side wall of the sedimentation tank 8 close to the bottom wall. For example, structurally, the lateral portion of the flow-through pipe 31 may be disposed on the surface wall surface of the sedimentation tank 8 through the bracket 11.
An observation valve 9 is provided at a downstream end of the lateral portion of the flow pipe 31 for observing the flow condition of water.
