[0002] Water injection test equipment in geological exploration of water conservancy and hydropower projects is used to measure the infiltration rate and permeability of fluids through rock and soil media to assess the flow characteristics of groundwater, help engineers understand the water flow characteristics of geological layers, and thus provide basic data for the design and construction of water conservancy and hydropower projects.

[0003] Geological investigation for water conservancy and hydropower projects is a crucial step in assessing the characteristics of underground soil and rock layers and the permeability of water flow. During the construction and design phases, geological investigation provides key information to ensure the safety and stability of the project. Water injection testing, a common method in geological investigation, is mainly used to detect the permeability, porosity, and water flow distribution characteristics of soil and rock layers. However, traditional water injection testing devices often suffer from problems such as cumbersome operation, inaccurate monitoring, and lack of automatic control, making them unsuitable for the needs of modern water conservancy and hydropower project geological investigation. Therefore, a new water injection testing device for water conservancy and hydropower project geological investigation is proposed to address these issues. Utility Model Content

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the connecting rod drives the eccentric wheel to rotate, and the upward movement of the pivot pin causes the T-block to slide and move the water box, which in turn moves the water injection pipe downward. At the same time, the water pump is started to draw water from the water tank to the water box, and then delivers it to the water injection pipe through the water supply pipe. The water enters the pre-drilled hole through the through hole for water injection experiment. When the water flows through the water supply pipe, the flow meter monitors the flow rate, the pressure sensor monitors the pressure change, and the counterweight ring ensures the balance of the water injection pipe during water injection. This achieves precise water injection and real-time monitoring of the water flow status, ensures operational balance, and provides support for experimental data analysis.

[0022] 2. In this utility model, by pushing the handle, the device is moved to the position to be tested. Then, the electric actuator is started, which drives the slider to move down, thereby driving the mounting plate and the drill bit to move down into the through hole. Then, the motor is started, which makes the drill bit rotate to drill. The slider slides in the support frame and the mounting plate slides outside the slide rod, which ensures the stability of the drill bit when it moves down. This realizes the automation and precise control of the drilling operation, eliminating the need for additional drilling equipment and improving the practicality and convenience of the device.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-3 An embodiment of this utility model provides a water injection test device for geological exploration of water conservancy and hydropower projects, including a base plate 1, a water tank 12 fixedly connected to the upper left side of the base plate 1, a water pump 13 fixedly connected to the upper part of the water tank 12, a water delivery pipe 15 fixedly connected to the output end of the water pump 13, a flow meter 14 installed on one side of the water delivery pipe 15, a water box 16 fixedly connected to one end of the water delivery pipe 15, a water injection pipe 17 fixedly connected to the bottom right side of the water box 16, a pressure sensor 18 installed on the lower side of the water injection pipe 17, a counterweight ring 19 installed on the outside of the pressure sensor 18, T-shaped blocks 25 fixedly connected to both the front and rear sides of the water box 16, a drive assembly installed on the front side of the front T-shaped block 25, the drive assembly being used to drive the water injection pipe 17 downward to inject water into the drilled holes;

[0030] The drive assembly includes an electric actuator 21, which is fixedly connected to the upper left front side of the base plate 1. A connecting rod 22 is fixedly connected to the output end of the electric actuator 21. An eccentric wheel 23 is rotatably connected to the outer front side of the connecting rod 22. A pivot pin 24 is rotatably connected to one side of the inner side of the eccentric wheel 23. The rear end of the pivot pin 24 is fixedly connected to the front side of the T-block 25. A connecting frame 20 is installed on the rear side of the electric actuator 21. The water box 16 and the T-block 25 are slidably connected inside the connecting frame 20. A sliding rod 26 is fixedly connected to both the front and rear sides of the inner side of the connecting frame 20. The water box 16 is slidably connected to the outside of the sliding rod 26.

[0031] After the hole is drilled, the electric actuator 21 is activated, which drives the eccentric wheel 23 via the connecting rod 22, causing it to rotate and move upward outside the pivot pin 24. This causes the wheel to slide upward through the T-block 25 within the connecting frame 20, moving the water box 16. The water box 16 then slides outside the sliding rod 26, causing the water injection pipe 17 to move downward, ensuring the stability of the water box 16 during movement. Simultaneously, the water pump 13 is activated to draw water from the water tank 12, which is then delivered into the water box 16 via the water supply pipe 15. The water injection pipe 17 then enters the drilled hole through the through hole 11 to inject water for the experiment. As the water flows into the water supply pipe 15, the flow rate is monitored by the flow meter 14, and the pressure changes are monitored by the pressure sensor 18. The external counterweight ring 19 ensures the balance of the water injection pipe 17 during water injection while monitoring the pressure, achieving precise water injection and real-time monitoring of the water flow status, ensuring operational balance, and providing support for experimental data analysis.

[0032] Reference Figure 1 and Figure 2 A support frame 4 is fixedly connected to the upper right rear side of the base plate 1. An electric push rod 5 is installed inside the rear side of the support frame 4. A slider 6 is fixedly connected to the output end of the electric push rod 5. A mounting plate 7 is fixedly connected to the front side of the slider 6. A motor 9 is fixedly connected to the upper front side of the mounting plate 7. A drill bit 10 is fixedly connected to the output end of the motor 9. A sliding rod 8 is fixedly connected to the bottom front side of the support frame 4. The mounting plate 7 is slidably connected to the outside of the sliding rod 8. The slider 6 is slidably connected to the inside of the support frame 4. A through hole 11 is opened inside the right side of the base plate 1.

[0033] A handle 2 is fixedly connected to the left side of the base plate 1, and casters 3 are fixedly connected to the four corners of the bottom of the base plate 1.

[0034] By pushing handle 2, the device is moved to the desired test position. Then, the electric actuator 5 is activated, causing it to move the mounting plate 7 downward via slider 6, thus moving the drill bit 10 into the through hole 11. The motor 9 is then activated, causing the drill bit 10 to rotate and drill. The drill bit 10 slides inside the support frame 4 via slider 6 and outside the mounting plate 7 via slide rod 8, ensuring smooth downward movement of the drill bit 10. After drilling is completed, the electric actuator 5 is activated again to raise the drill bit 10. This achieves automated and precise control of the drilling operation, eliminating the need for additional drilling equipment and improving the practicality and convenience of the device.

[0035] Working principle: When the device is needed, push handle 2 to move the device to the desired test position. Then, start electric actuator 5, which moves slider 6 downward, thereby moving mounting plate 7 and drill bit 10 into through hole 11. Next, start motor 9 to rotate drill bit 10 to drill. Sliding slider 6 slides within support frame 4, and mounting plate 7 slides outside sliding rod 8, ensuring the stability of drill bit 10 during downward movement. After drilling is completed, start electric actuator 5 again to raise drill bit 10, and then start electric actuator 21. The connecting rod 22 drives the eccentric wheel 23 to rotate, and the pivot pin 24 moves upward, causing the T-block 25 to slide and move the water box 16, which in turn moves the water injection pipe 17 downward. At the same time, the water pump 13 is started to pump water from the water tank 12 to the water box 16, and then delivers it to the water injection pipe 17 through the water supply pipe 15. The water enters the pre-drilled hole through the through hole 11 for water injection experiment. When the water flows through the water supply pipe 15, the flow meter 14 monitors the flow rate, the pressure sensor 18 monitors the pressure change, and the counterweight ring 19 ensures the balance of the water injection pipe 17 during water injection.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
