Description

Technical Field

[0001] The present application relates to the technical field of water conservancy and geological exploration, and in particular to a water seepage test device for water conservancy and geological exploration. Background Art

[0002] Water conservancy geological survey is an indispensable part of modern engineering construction and environmental protection. By accurately measuring the flow characteristics of groundwater, the permeability of the stratum can be effectively evaluated, providing a scientific basis for engineering design and construction.

[0003] At present, a general water seepage test device includes a support frame, a sample container, and a water storage tank. The sample container is arranged on the support frame and is used to hold the soil sample to be tested. The sample container is made of transparent material; the water storage tank is arranged on the support frame and is connected to the sample container through a conduit; a scale is arranged in the sample container to facilitate intuitive reading of the liquid level.

[0004] However, during the test, the above device relies on gravity to supply water, which makes it difficult to accurately control the water pressure, resulting in poor repeatability and reliability of the experimental results, affecting the accuracy of the test results. Summary of the invention

[0005] In order to improve the accuracy of the test results, the present application provides a water seepage test device for water conservancy and geological survey.

[0006] The present application provides a water seepage test device for water conservancy and geological exploration, which adopts the following technical solution: A water seepage test device for water conservancy and geological survey, comprising: Support frame; A double ring frame is arranged on the support frame; Adjustment components, including: An adjusting part, arranged on the supporting frame and used for adjusting the horizontal state of the double ring frame; A locking portion, disposed on the support frame and used to lock the adjustment state of the adjusting portion; A pressure assembly, disposed on the support frame and used to press the double ring frame into the ground; The drainage component is arranged on the support frame and is used to add water into the double ring frame to perform a water seepage test.

[0007] By adopting the above technical solution, when the support frame is placed on the test site, the adjustment part can accurately adjust the horizontal state of the double ring frame. After the adjustment, the locking part fixes the adjusted state of the adjustment part to prevent the position of the double ring frame from changing due to external factors during the test, ensuring that the double ring frame can remain horizontal during the water seepage test, thereby eliminating the error caused by the tilt of the device, thereby ensuring the accuracy of the test; Then, the pressure component can press the double ring frame into the ground to a predetermined depth, and the drainage component adds water into the double ring frame to conduct a water seepage test. Through the synergistic effect of the adjustment component and the pressure component, it can adapt to soil conditions of different hardness and depth.

[0008] Optionally, the adjustment unit includes: A fixed plate, fixed on the support frame and provided with a rotation hole; There are two limit blocks, which are arranged opposite to each other and fixed in the rotating hole, wherein the limit blocks are provided with a sliding groove; Two inner ratchets are provided, the two inner ratchets are stacked and fixed, and are both rotatably connected in the rotating hole, the two inner ratchets are located in the sliding groove, and the ratchet teeth of the two are arranged in opposite directions, and the inner ratchets are connected to the double ring frame through the pressure assembly; There are two pawls, which correspond to the two inner ratchets one by one, and are engaged with the inner ratchets, wherein a pressure spring is fixed between the pawl and the support frame.

[0009] By adopting the above technical solution, when the double ring frame tilts to one side, under the action of gravity, the double ring frame drives the inner ratchet to rotate, and when the double ring frame is in a horizontal state, the ratchet pawl will automatically get stuck in the ratchet teeth of the inner ratchet to prevent it from rotating, thereby ensuring the stability of the double ring frame during the test; By stacking and fixing two inner ratchets and arranging the ratchets in opposite directions, bidirectional adjustment of the horizontal state of the double ring frame can be achieved, thereby greatly improving the flexibility and accuracy of the adjustment.

[0010] Optionally, the locking parts are provided in two groups, the two groups of locking parts correspond to the two pawls one by one, and the locking parts include: A water storage box, fixed on the fixed plate; An adjustable telescopic rod is fixedly mounted on the fixing plate, and has a rod cavity communicating with the water storage box, wherein a return spring is fixedly mounted in the rodless cavity of the adjustable telescopic rod; A booster box, fixed on the fixed plate; A slide plate is slidably connected in the pressurizing box, and the movable end of the adjusting telescopic rod is passed through the pressurizing box and fixedly connected to the slide plate; The two ends of the bellows are respectively fixedly connected to the pawl and the support frame, the pressure spring is located in the bellows, the bellows is connected to the boost box, and the connection point is located on the side of the slide away from the adjustable telescopic rod.

[0011] By adopting the above technical solution, when the double ring frame tilts to one side, the fixed plate drives the water storage box to tilt, and since the rod cavity of the adjustable telescopic rod is connected with the water storage box, the water in the water storage box flows into the rod cavity of the adjustable telescopic rod, and the water squeezes the movable end of the adjustable telescopic rod to retract, and the movable end of the adjustable telescopic rod drives the slide plate to slide, thereby increasing the pressure in the boosting box, sucking the water in the bellows into the boosting box, compressing the space in the bellows, so that the pawl and the inner ratchet can be locked; At the same time, the water in the other water storage box flows back from the rod cavity of the other adjustable telescopic rod. Under the elastic force of the reset spring, the movable end of the other adjustable telescopic rod is reset, so that the other slide is reset, reducing the pressure in the other booster box, squeezing the water back into the bellows, releasing the space in the bellows, and disengaging the other pawl from the other inner ratchet, thereby facilitating the switching of the pawl to the locked state, thereby ensuring the safety of the water seepage test device.

[0012] Optionally, the pressure applying component includes: An electric telescopic rod, a fixed end of which is fixedly connected to the inner ratchet, and a movable end of which is connected to the double ring frame; A reinforcing plate is fixedly connected to the movable end of the electric telescopic rod on one side, and is fixedly connected to the double ring frame on the other side.

[0013] By adopting the above technical solution, when the double-ring frame is adjusted to a horizontal state, the electric telescopic rod is started by an external control source, and the movable end of the electric telescopic rod drives the reinforcing plate to press down, and the reinforcing plate presses the double-ring frame into the test ground, thereby greatly simplifying the operating process of the water seepage test and improving the test efficiency.

[0014] Optionally, the double ring frame includes: An outer ring, fixedly connected to the reinforcing plate; An inner ring, fixedly connected to the reinforcing plate; A plurality of webs are provided, the plurality of webs are arranged around the axis direction of the inner ring, and the webs are fixedly connected to the outer ring and the inner ring; Wherein, water seepage holes are opened on the web.

[0015] By adopting the above technical solution, during the test, water is added to the inner ring and the annular space between the inner and outer rings respectively. The inner ring is used to control the experimental area, while the outer ring ensures that the solution in the inner ring infiltrates vertically while reducing lateral seepage. By measuring the amount of water infiltration per unit surface area per unit time (i.e., the infiltration rate) and combining it with Darcy's law, the vertical permeability coefficient of the soil can be calculated.

[0016] Optionally, the drainage component includes: A water tank is fixed on the reinforcing plate; Two drainage pipes are provided, both of which are connected to the water tank and are located inside and outside the inner ring respectively; Wherein, a solenoid valve is arranged on the drainage pipe.

[0017] By adopting the above technical solution, the solenoid valve is opened through an external control source, and the water in the water tank is added to the inner ring and the annular space between the inner and outer rings through the drainage pipe, respectively, and the drainage flow rate is accurately adjusted, thereby facilitating a more accurate simulation of actual groundwater seepage conditions.

[0018] Optionally, the ends of the inner ring and the outer ring close to the ground are both wedge-shaped.

[0019] By adopting the above technical solution, when the pressure component presses down the double-ring frame, due to the wedge-shaped design, the inner ring and the outer ring can more easily cut into the soil when buried, thereby easily reducing the difficulty of burying.

[0020] Optionally, the bottom end of the support frame is conical.

[0021] By adopting the above technical solution, the support frame is easier to insert into the soil, especially in soft or sandy soil, thereby simplifying the installation process and further reducing the installation time and labor costs.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: By setting the adjustment part and the locking part, it is ensured that the double ring frame can keep level during the water seepage test, thereby eliminating the error caused by the tilt of the device and ensuring the accuracy of the test; By setting up a pressure component, the movable end of the electric telescopic rod drives the reinforcement plate to press down, and the reinforcement plate presses the double ring frame into the test ground, thereby greatly simplifying the operation process of the water seepage test and improving the test efficiency; By setting up a drainage component and adding water to the inner ring and the annular space between the inner and outer rings through the drainage pipe, the drainage flow rate can be accurately adjusted, thereby simulating the actual groundwater seepage situation more accurately.

The inner ratchets 313 are connected to the double ring frame 2 through the pressure component 4 .

[0034] Reference Figure 3 and Figure 4 There are two ratchet pawls 314, which correspond to the two inner ratchet wheels 313 one by one. The ratchet pawl 314 is engaged with the inner ratchet wheels 313. A pressure spring 315 is fixed between the ratchet pawl 314 and the fixing plate 311. In the initial state, the pressure spring 315 is in a stretched state.

[0035] Reference Figure 1 , Figure 3 and Figure 4 There are two groups of locking parts 32, and the two groups of locking parts 32 correspond to the two pawls 314 one by one. The locking part 32 includes a water storage box 321, an adjustable telescopic rod 322, a booster box 323, a slide plate 324 and a bellows 325. The water storage box 321 is fixed on the fixed plate 311.

[0036] Reference Figure 1The adjustable telescopic rod 322 is fixed on the fixed plate 311, and the rod cavity is connected to the water storage box 321 by a conduit 3221. Water flows between the adjustable telescopic rod 322 and the water storage box 321 through the conduit 3221. A return spring 3222 is fixed in the rodless cavity of the adjustable telescopic rod 322. The two ends of the return spring 3222 are respectively fixedly connected to the fixed end and the movable end of the adjustable telescopic rod 322. In the initial state, the return spring 3222 is in a stretched state.

[0039] When in use, when the double ring frame 2 tilts to one side, the double ring frame 2 drives the inner ratchet 313 to rotate, so that the double ring frame 2 is in a horizontal state. At the same time, the fixing plate 311 drives the water storage box 321 to tilt, and the water in the water storage box 321 flows into the rod cavity of the adjusting telescopic rod 322. The water squeezes the movable end of the adjusting telescopic rod 322 to retract, and the movable end of the adjusting telescopic rod 322 drives the slide plate 324 to slide, thereby increasing the pressure in the boosting box 323 and sucking the water in the bellows 325 into the boosting box 323, so that the pawl 314 and the inner ratchet 313 can be locked; At the same time, the water in the other water storage box 321 flows back from the rod cavity of the other adjustable telescopic rod 322. Under the elastic force of the reset spring 3222, the movable end of the other adjustable telescopic rod 322 is reset, so that the other slide plate 324 is reset, the pressure in the other booster box 323 is reduced, and the water is squeezed into the bellows 325 again, releasing the space in the bellows 325, so that the other ratchet 314 is disengaged from the other inner ratchet 313.

[0043] When in use, the solenoid valve 53 is opened through an external control source, and the water in the water tank 51 is added to the inner ring 22 and the annular space between the inner and outer rings 21 through the drainage pipe 52, so that the drainage flow rate can be accurately adjusted, thereby simulating the actual groundwater seepage conditions more accurately.

[0044] The implementation principle of a water seepage test device for water conservancy and geological survey in the embodiment of the present application is as follows: the support frame 1 is placed on the test ground, and the pressure cone 3112 is inserted into the ground. When the double-ring frame 2 tilts to one side, the double-ring frame 2 drives the inner ratchet 313 to rotate, so that the double-ring frame 2 is in a horizontal state. At the same time, the fixed plate 311 drives the water storage box 321 to tilt, and the water in the water storage box 321 flows into the rod cavity of the adjusting telescopic rod 322. The water squeezes the movable end of the adjusting telescopic rod 322 to retract, and the movable end of the adjusting telescopic rod 322 drives the slide plate 324 to slide, thereby increasing the pressure in the boosting box 323 and sucking the water in the bellows 325 into the boosting box 323, so that the pawl 314 and the inner ratchet 313 can be locked. At the same time, the water in the other water storage box 321 flows back from the rod cavity of the other adjustable telescopic rod 322. Under the elastic force of the reset spring 3222, the movable end of the other adjustable telescopic rod 322 is reset, so that the other slide plate 324 is reset, the pressure in the other booster box 323 is reduced, and the water is squeezed into the bellows 325 again, releasing the space in the bellows 325, so that the other ratchet 314 is disengaged from the other inner ratchet 313. Conversely, when the double ring frame 2 tilts to the other side, the water in the two water storage boxes 321 flows in opposite directions, so that the adjustment and locking in the opposite direction can be achieved, so that it is easy to switch the locking state of the ratchet 314, thereby ensuring the safety of the water seepage test device; When the double-ring frame 2 is in a horizontal state, the movable end of the electric telescopic rod 41 drives the reinforcing plate 42 to press down, and the reinforcing plate 42 presses the double-ring frame 2 into the test ground. The water in the water tank 51 is added to the inner ring 22 and the annular space between the inner and outer rings 21 through the drainage pipe 52, and the drainage flow rate is accurately adjusted, so that it is easy to more accurately simulate the actual groundwater seepage situation.
