Specific implementation manner

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Such as Figures 1-9As shown in the figure, the utility model provides a technical solution: a measuring device for reservoir leakage monitoring, including a drilling cylinder 1. The bottom end of the drilling cylinder 1 is threadedly connected with a second connecting piece 8 through a threaded groove, and the bottom of the second connecting piece 8 is fixedly connected with a drill bit 9. One end of the drilling cylinder 1 is fixedly connected with a first connecting piece 3, and the other end is provided with a connecting groove 7. The outer wall of the first connecting piece 3 is provided with threads, and another first connecting piece 3 is threadedly connected with the connecting groove 7 of another drilling cylinder 1 to realize the expansion of the drilling cylinder 1 and adapt to drilling operations of different depths. The outer wall of the drilling cylinder 1 is fixedly connected with a rotating plate 2, and a capillary material 6 is fixedly connected to the outer wall through a through hole. The material of the rotating plate 2 improves the accuracy and drilling efficiency. A spring block 5 is fixedly connected to the inner wall of the center of the capillary material 6, which helps to reduce the impact on the surrounding environment during the drilling process. At the same time, the spring block 5 can provide additional supporting force, and when the humidity sensor 14 passes by, the capillary material 6 is stressed to drive the spring block 5 to bend, and the reaction force generated by the spring block 5 makes the capillary material 6 closely fit with the humidity sensor 14, improving the monitoring accuracy of the device. At the same time, when the humidity sensor 14 is separated from the capillary material 6, the capillary material 6 resets under the action of the spring block 5, facilitating the next detection. A positioning block 10 is fixedly connected to the inner wall of the end of the drilling cylinder 1 far from the drill bit 9. The positioning block 10 is rotatably connected with a lead screw 11 through a first bearing. The top of the lead screw 11 is fixedly connected with a connecting head 12, and the bottom is provided with a threaded groove. The threaded groove of another lead screw 11 is threadedly connected with the connecting head 12 of the lead screw 11 located at the bottom, and the bottom of the lead screw 11 located at the bottom is rotatably connected with the drill bit 9 through a second bearing. The design of the connecting head 12 and the threaded groove facilitates the expansion of the lead screw 11 so that the humidity sensor 14 can adapt to the monitoring requirements of different depths. A moving block 13 is threadedly connected to the outer wall of the lead screw 11. Humidity sensors 14 are clamped on both sides of the moving block 13. The humidity sensors 14 are movably clamped with the moving block 13 through a clamping groove and a clamping plate 16. The clamping of the humidity sensors 14 with the moving block 13 enables the humidity sensors 14 to be conveniently installed and disassembled, facilitating maintenance and replacement. The humidity sensors 14 are closely attached to the capillary material 6, which can ensure that the humidity sensors 14 can accurately sense the humidity changes in the capillary material 6, improving the sensitivity and accuracy of the monitoring. By absorbing the moisture through the capillary material 6, the leakage situation is judged. A spring 15 is fixedly connected to the inner wall of the top of the cavity of the moving block 13 through a spring groove. The other end of the spring 15 is fixedly connected with a clamping plate 16. A clamping plate groove is provided at the top of the moving block 13, and rotating rods are rotatably connected to the inner walls on both sides of the clamping plate groove. The outer wall of the rotating rod is fixedly connected with the clamping plate 16. The cooperation of the spring 15 and the clamping plate 16 enables the humidity sensors 14 to be stably clamped under the action of the spring 15 and the clamping plate 16, ensuring that the humidity sensors 14 will not be separated from the moving block 13 due to vibration or collision. At the same time, it is convenient to install and disassemble the humidity sensors 14. Rubber pads 4 are fixedly connected to the outer walls of the drill bit 9 and the top of the drilling cylinder 1 at the positions of the first connecting piece 3 and the second connecting piece 8.The setting of the rubber pad 4 can ensure the tightness of the connection part and effectively prevent moisture and sediment from entering the inside of the drilling cylinder 1, thereby ensuring the accuracy of the monitoring data. A handle 17 is fixedly connected to one side of the inner cavity top of the clamping plate 16 close to the moving block 13. The design of the handle 17 facilitates the staff to pull the clamping plate 16 through the handle 17 to install or disassemble the humidity sensor 14.

[0034] Working principle: When in use, first install the drilling cylinder 1 and the drilling equipment at the position where drilling is required. The drilling equipment drives the drilling cylinder 1 to rotate and then inserts the drilling cylinder 1 into the ground. The top of the lead screw 11 is connected to the motor through the connector 12 to drive the lead screw 11 to rotate and drive the moving block 13 to move. The humidity sensor 14 moves accordingly for monitoring. When deeper drilling is required, the drilling cylinder 1 can be extended through the cooperation of the drilling cylinder 1, the connecting piece 3 and the other connecting groove 7 to meet the monitoring requirements of different depths. Among them, the bottom connecting groove 7 is connected to the drill bit 9 through the connecting piece 8 to realize the drilling operation at places such as reservoir dams. The design of the rotating plate 2 helps to improve the accuracy and stability of drilling. The lead screw 11 is threadedly connected to the connecting head 12 at the top of the other lead screw 11 through the thread groove at the bottom, which is convenient for extension. At the same time, the outer wall of the lead screw 11 is threadedly connected with the moving block 13. When the lead screw 11 rotates, the moving block 13 moves along the lead screw 11, driving the humidity sensor 14 to move up and down in the drilling cylinder 1 to detect the leakage conditions at different depths. When the humidity sensor 14 passes by, the capillary material 6 is stressed to drive the elastic block 5 to elastically adhere tightly. The reaction force generated by the elastic block 5 makes the capillary material 6 closely fit with the humidity sensor 14, improving the monitoring accuracy. At the same time, when the humidity sensor 14 is separated from the capillary material 6, the capillary material 6 resets under the action of the elastic block 5, facilitating the next detection. Among them, through the setting of the elastic block 5 and the capillary material 6, it is ensured that the soil of the reservoir dam will not affect the humidity sensor 14 inside the drilling cylinder 1. Thus, the capillary material 6 absorbs the moisture in the soil and is monitored through the humidity sensor 14, improving the accuracy of monitoring the leakage of the reservoir dam.
