Description

Technical Field

[0001] The invention belongs to the technical field of water seepage test, in particular to a water seepage test device for water conservancy and geological survey. Background Art

[0002] The double-ring water injection test device is a commonly used high-precision device for water seepage test in hydrogeological survey, especially for field determination of permeability coefficient of unsaturated loose rock formation in aeration zone. The double-ring water injection test device is mainly composed of inner ring, outer ring and water injection device. The working principle of the device is based on Darcy's law, that is, within a certain hydrogeological boundary, water is injected into the loose rock formation on the surface to make the infiltrated water reach a stable state (that is, the infiltrated water volume per unit time is approximately equal). At this time, the permeability coefficient (K) value can be calculated using the principle of Darcy's law.

[0003] When the water seepage test device is in use, the inner ring and the outer ring are inserted into the soil at the same time and kept at the same height, and water is injected into the inner ring and the outer ring at the same time to conduct a water seepage test. However, since the amount of water stored in the external water injection device is limited, the water injection device needs to be replenished with water during the water seepage test. However, the water injection device currently used needs to be manually injected after the water has completely flowed out, and the liquid levels inside the two water injection pipes cannot be kept level, which affects the measurement accuracy of the water seepage coefficient.

[0004] At the same time, when conducting a water seepage test, when water needs to be supplemented, the water injection device is usually replenished to a specified value and then the water replenishment is stopped. However, the currently used device needs to count each water replenishment operation when replenishing water in order to obtain the water injection volume. The entire test process is rather cumbersome and urgently needs to be improved. Summary of the invention

[0005] The purpose of the present invention is to provide a water seepage test device for water conservancy and geological survey to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical scheme: a water seepage test device for water conservancy and geological survey, comprising a base plate, a frame is fixedly installed on the top of the base plate, a fixing piece is fixedly installed on the bottom end of the base plate, an outer ring is movably connected to the bottom end of the base plate near the outer side surface through a fixing piece, an inner ring is movably connected to the bottom end of the base plate near the inner side surface through a fixing piece, the inner ring is located on the inner side surface of the outer ring, water injection tanks are fixedly installed on the top end of the base plate near the left and right sides, a through hole is opened at the top end of the base plate near the left and right sides and is located directly below the water injection tank, and the front and rear ends of the two water injection tanks near the bottom are connected. Drain pipes are fixedly connected on both sides, and a No. 2 three-way valve is fixedly connected between the two drainage pipes. The bottom end of the No. 2 three-way valve passes through the bottom end of the through hole and is respectively connected to the inside of the inner ring and the outer ring. A connecting pipe is fixedly connected between the bottom ends of the two water injection tanks. A water storage tank is fixedly sleeved on the middle part of the top of the frame. A transverse guide rail is provided at the bottom end of the water storage tank. Adjustment components are movably connected on the left and right sides of the transverse guide rail. Self-watering components are installed at the relatively far ends of the two adjustment components. The other end of the self-watering component is connected to one side of the frame, and the bottom ends of the two self-watering components are connected to the tops of the two water injection tanks.

[0007] Before use, the device must first be placed in the area to be tested, and excavation operations must be performed, and the inner and outer rings at the bottom must be buried in the soil at the same time. It must be ensured that the inner and outer rings are buried to the same depth, and water must be injected into the water tank to complete the water replenishment preparation.

[0008] As a further technical solution of the present invention, a mounting block is fixedly installed in the middle of the top end of the transverse guide rail, a No. 1 three-way valve is fixedly installed on the top end of the mounting block, and the top end of the No. 1 three-way valve is connected to the middle of the bottom end of the water tank.

[0009] As a further technical solution of the present invention, the left and right sides of the No. 1 three-way valve are fixedly connected with water pipes, and one end of the water pipe away from the No. 1 three-way valve is fixedly connected to the self-filling assembly.

[0010] When conducting a water seepage experiment, the valve of the No. 1 three-way valve can be opened. At this time, the water flow inside the water storage tank can be discharged through the water pipes at both ends of the No. 1 three-way valve, and enter the interior of the two self-filling components through the water pipes, and finally enter the interior of the two water injection tanks through the water pipes to complete the water replenishment operation.

[0011] As a further technical solution of the present invention, the interiors of the two water tanks are movably sleeved with floating plates, an extension rod is fixedly installed in the middle of the top of the floating plate, the top of the extension rod passes through the middle of the top of the water tank and is connected to the adjustment component.

[0012] As a further technical solution of the present invention, the adjustment assembly includes a movable plate located above the water injection tank, and a first fixed seat is fixedly installed on the left and right sides of the top of the movable plate near the middle, and the end of the first fixed seat away from the movable plate is movably connected to a connecting rod through a rotating shaft, and the end of the connecting rod away from the first fixed seat is movably connected to a second fixed seat through a rotating shaft.

[0013] As a further technical solution of the present invention, a guide block is fixedly installed on the top of the connecting rod, the guide block is movably connected to the transverse guide rail, the guide block is displaced left and right relative to the transverse guide rail, and the top of the guide block is connected to the self-watering component.

[0014] The water flowing into the two water injection tanks can be discharged through the drainage pipes at the front and rear ends and enter the interior of the No. 2 three-way valve. At this time, the bottom ends of the two No. 2 three-way valves can simultaneously discharge the water flow and inject the water flow into the inner ring and the outer ring respectively to complete the water injection operation for the water seepage experiment. At the same time, since the bottom ends of the two water injection tanks are connected with a connecting pipe, the two water injection tanks are actually connected to each other. At this time, the liquid level height of the two water injection tanks will always remain consistent, ensuring that the water injection height inside the inner ring and the outer ring is the same, thereby ensuring the accuracy of the water seepage experiment.

[0015] By utilizing the cooperation between the connecting pipe and the two water injection tanks, that is, utilizing the principle of liquid pressure, the liquid level height inside the two water injection tanks is kept consistent at all times, thereby ensuring that the height of the liquid injected into the inner ring and the outer ring is always consistent. The entire process is completed automatically, which can effectively ensure the consistency of the injected liquid height, minimize the error of the water seepage test, and improve the accuracy of the water seepage test.

[0016] As a further technical solution of the present invention, the self-filling assembly includes a water collecting tank, one side of the water collecting tank is connected to the inner side of the frame, the middle part of the top of the water collecting tank is connected to the water pipe, a guide groove is provided at the bottom end of the water collecting tank, the bottom end of the guide groove is fixedly connected to an electromagnetic drain valve, and the bottom end of the electromagnetic drain valve is connected to the top of the water filling tank.

[0017] As a further technical solution of the present invention, the internal movable clamp of the water collecting box is connected with a sealing plate, the bottom end of the sealing plate is connected to the top end of the guide block, and when the floating plate is at the lowest point, the movable plate is also at the lowest point and the sealing plate is at the rightmost position.

[0018] As a further technical solution of the present invention, touch counters are fixedly installed on both sides of the bottom of the floating plate. When the bottom of the touch counter is connected to the bottom of the water injection tank, the floating plate is at the lowest point.

[0019] When the water flow inside the two water filling tanks is exhausted, the buoyancy of the liquid surface causes the float plate to drop to the lowest point. At this time, the touch counter at the bottom of the float plate contacts the bottom of the inner cavity of the water filling tank, completing a counting process. At this time, the electromagnetic drain valve can be automatically opened. At this time, the water flow inside the water storage tank can be introduced into the interior of the water filling tank through the No. 1 three-way valve and the water supply pipe, the water collecting tank and the electromagnetic drain valve in turn to complete the automatic water replenishment process and complete the automatic water replenishment operation.

[0020] By utilizing the buoyancy of the water flow, that is, the float plate drops when the water flow is exhausted, automatic counting is achieved, and the switch is automatically triggered to automatically open the electromagnetic drain valve for automatic water replenishment. This allows the device to automatically replenish water when the water flow is exhausted. The entire process is completed automatically, and the water replenishment of the two water filling tanks is completed synchronously, avoiding the problems of manual water replenishment and manual counting required in traditional devices, thereby improving the convenience of using the device.

[0021] And in the process of water injection, as the height of the liquid level inside the water injection tank rises, the buoyancy increases accordingly, and the two floating plates rise synchronously, and drive the extension rod to move upward until the movable plate is driven to move upward first. At this time, the distance between the movable plate and the transverse guide rail is shortened accordingly, and the two connecting rods are driven to deflect in the direction away from the middle. At this time, the two guide blocks are acted upon by thrust, which drives the two sealing plates away from each other. When the sealing plate is displaced to the leftmost position, the top of the water collecting tank can be completely sealed at this time, and the injection process of the water flow from the water injection tank is automatically cut off. When the sealing plate is displaced to the leftmost position, the valve of the electromagnetic drain valve can be automatically closed at this time, completing the automatic cut-off process when the water flow is full.

[0022] By utilizing the buoyancy of the water flow inside the water injection tank again, that is, when the water flow inside the water injection tank is full, through the upward displacement of the float plate, and the cooperation between the adjustment component and the self-injection component, the device can automatically cut off the water injection, and the whole process is still completed automatically. It can effectively avoid the problem of traditional devices not closing in time after the water flow is full, resulting in water overflow and affecting the water seepage experiment, and further improve the test accuracy of the water seepage experiment.

[0023] The beneficial effects of the present invention are as follows:

[0024] (1) The present invention utilizes the buoyancy of water flow, that is, the floating plate drops when the water flow is exhausted, realizes automatic counting, and automatically triggers the switch to realize the automatic opening of the electromagnetic drain valve for automatic water replenishment, so that the device can automatically replenish water when the water flow is exhausted. The whole process is completed automatically, and the water replenishment of the two water filling tanks is completed synchronously, avoiding the problems of manual water replenishment and manual counting required by traditional devices, thereby improving the convenience of using the device.

[0025] (2) The present invention utilizes the buoyancy of the water flow inside the water injection tank again. That is, when the water flow inside the water injection tank is full, the upward displacement of the float plate and the cooperation between the adjustment component and the self-injection component enable the device to automatically cut off the water flow injection. The whole process is still completed automatically, which can effectively avoid the problem of traditional devices not being closed in time after the water flow is full, resulting in water overflow and affecting the water seepage experiment, and further improve the test accuracy of the water seepage experiment.

[0026] (3) The present invention utilizes the cooperation between the connecting pipe and the two water injection tanks, that is, utilizes the principle of liquid pressure to ensure that the liquid levels inside the two water injection tanks remain consistent at all times, thereby ensuring that the liquid heights injected into the inner ring and the outer ring remain consistent at all times. The entire process is completed automatically, which can effectively ensure the consistency of the injected liquid height, minimize the error of the water seepage test, and improve the accuracy of the water seepage test.

[0039] Before use, the device must first be placed in the area to be tested, and excavation operations must be performed, and the inner ring 4 and outer ring 5 at the bottom must be buried in the soil at the same time. It must be ensured that the inner ring 4 and outer ring 5 are buried to the same depth, and water must be injected into the water tank 7 to complete the water replenishment preparation.

[0040] like Figure 1 and Figure 2 as well as Figure 4 and Figure 5 As shown, a mounting block 8 is fixedly installed in the middle of the top end of the transverse guide rail 17, and a No. 1 three-way valve 9 is fixedly installed on the top end of the mounting block 8. The top end of the No. 1 three-way valve 9 is connected to the middle of the bottom end of the water storage tank 7, and the left and right sides of the No. 1 three-way valve 9 are fixedly connected with a water pipe 10, and the end of the water pipe 10 away from the No. 1 three-way valve 9 is fixedly connected to the self-filling component 19.

[0041] When conducting a water seepage experiment, the valve of the No. 1 three-way valve 9 can be opened. At this time, the water flow inside the water storage tank 7 can be discharged through the water pipes 10 at both ends of the No. 1 three-way valve 9, and enter the interior of the two self-injection components 19 through the water pipes 10, and enter the interior of the two self-injection components 19 through the water pipes 10, and finally enter the interior of the two water injection tanks 11 through the water pipes 10 to complete the water replenishment operation.

[0042] like Figure 1 and Figure 4 as well as Figure 6 and Figure 7 As shown, the interiors of the two water storage tanks 7 are movably sleeved with a floating plate 15, and an extension rod 16 is fixedly installed in the middle of the top of the floating plate 15. The top of the extension rod 16 passes through the middle of the top of the water storage tank 7 and is connected to the adjusting component 18. The adjusting component 18 includes a movable plate 181 located above the water injection tank 11, and the first fixed seat 182 is fixedly installed on the top and left and right sides near the middle of the movable plate 181. The end of the first fixed seat 182 away from the movable plate 181 is movably connected to a connecting rod 184 through a rotating shaft, and the end of the connecting rod 184 away from the first fixed seat 182 is movably connected to a second fixed seat 183 through a rotating shaft.

The top of the guide block 185 is connected to the self-injection component 19.

[0043] The water flowing into the two water injection tanks 11 can be discharged through the drainage pipes 13 at the front and rear ends and enter the interior of the No. 2 three-way valve 14. At this time, the bottom ends of the two No. 2 three-way valves 14 can simultaneously discharge the water flow and inject the water flow into the inner ring 4 and the outer ring 5 respectively, completing the water injection operation to carry out a water seepage experiment. At the same time, since the bottom ends of the two water injection tanks 11 are connected by a connecting pipe 12, the two water injection tanks 11 are actually connected to each other. At this time, the liquid level height of the two water injection tanks 11 will always remain consistent, ensuring that the water injection height inside the inner ring 4 and the outer ring 5 is the same, thereby ensuring the accuracy of the water seepage experiment.

[0044] By utilizing the cooperation between the connecting pipe 12 and the two water injection tanks 11, that is, utilizing the principle of liquid pressure, the liquid level height inside the two water injection tanks 11 is always kept consistent, thereby ensuring that the height of the liquid injected into the inner ring 4 and the outer ring 5 is always kept consistent. The entire process is completed automatically, which can effectively ensure the consistency of the injected liquid height, minimize the error of the water seepage experiment, and improve the accuracy of the water seepage experiment.

[0045] like Figure 4 and Figure 6 as well as Figures 7 to 9 As shown, the self-filling assembly 19 includes a water collecting box 191, one side of which is connected to the inner side of the frame 2, the middle of the top of the water collecting box 191 is connected to the water pipe 10, a guide groove 192 is provided at the bottom of the water collecting box 191, the bottom end of the guide groove 192 is fixedly connected with an electromagnetic drain valve 193, the bottom end of the electromagnetic drain valve 193 is connected to the top of the water injection tank 11, the internal movable card of the water collecting box 191 is connected with a sealing plate 194, the bottom end of the sealing plate 194 is connected to the top of the guide block 185, when the floating plate 15 is at the lowest point, the movable plate 181 is also at the lowest point and the sealing plate 194 is at the rightmost position, the left and right sides of the bottom end of the floating plate 15 are fixedly installed with a light touch counter 20, when the bottom end of the light touch counter 20 is connected to the bottom end of the water injection tank 11, the floating plate 15 is at the lowest point.

[0046] Embodiment: When the water flow inside the two water filling tanks 11 is exhausted, the buoyancy of the liquid surface causes the float 15 to drop to the lowest point. At this time, the touch counter 20 at the bottom of the float 15 contacts the bottom end of the inner cavity of the water filling tank 11, completing a counting process, and the electromagnetic drain valve 193 can be automatically opened at this time. At this time, the water flow inside the water storage tank 7 can be introduced into the interior of the water filling tank 11 through the No. 1 three-way valve 9 and the water pipe 10, the water collecting tank 191 and the electromagnetic drain valve 193 in sequence to complete the automatic water replenishment process and the automatic water replenishment operation.

[0047] By utilizing the buoyancy of the water flow, that is, the water flow is exhausted and causes the float plate 15 to drop, automatic counting is achieved, and the switch is automatically triggered to automatically open the electromagnetic drain valve 193 for automatic water replenishment, so that the device can automatically replenish the water when the water flow is exhausted. The whole process is completed automatically, and the water replenishment of the two water filling tanks 11 is completed synchronously, avoiding the problems of manual water replenishment and manual counting required in traditional devices, thereby improving the convenience of using the device.

[0048] Embodiment: During the water injection process, as the liquid level inside the water injection tank 11 rises, the buoyancy increases, and the two floating plates 15 rise synchronously, and drive the extension rod 16 to move upward until the movable plate 181 moves upward first. At this time, the distance between the movable plate 181 and the transverse guide rail 17 is shortened, and the two connecting rods 184 are driven to deflect away from the middle. At this time, the two guide blocks 185 are subjected to thrust, which drives the two sealing plates 194 away from each other. When the sealing plate 194 is displaced to the leftmost position, the top of the water collecting box 191 can be completely sealed, and the injection process of the water flow of the water injection tank 11 is automatically cut off. When the sealing plate 194 is displaced to the leftmost position, the valve of the electromagnetic drain valve 193 can be automatically closed to complete the automatic cut-off process when the water flow is full.

[0049] By utilizing the buoyancy of the water flow inside the water injection tank 11 again, that is, when the water flow inside the water injection tank 11 is full, through the upward displacement of the float plate 15, and the cooperation between the adjustment component 18 and the self-injection component 19, the device can automatically cut off the water injection, and the whole process is still completed automatically. It can effectively avoid the problem that the traditional device is not closed in time after the water flow is full, resulting in water overflow and affecting the water seepage experiment, and further improves the test accuracy of the water seepage experiment.

[0050] Working principle and usage process:

[0051] Before use, the device must first be placed in the area to be tested, and excavation operations must be performed, and the inner ring 4 and the outer ring 5 at the bottom must be buried in the soil at the same time, and it must be ensured that the inner ring 4 and the outer ring 5 are buried to the same depth, and water must be injected into the water storage tank 7 to complete the water replenishment preparation;

[0052] When conducting a water seepage experiment, the valve of the No. 1 three-way valve 9 can be opened. At this time, the water flow inside the water storage tank 7 can be discharged through the water pipes 10 at both ends of the No. 1 three-way valve 9, and enter the interior of the two self-injection components 19 through the water pipes 10, and enter the interior of the two self-injection components 19 through the water pipes 10, and finally enter the interior of the two water injection tanks 11 through the water pipes 10, completing the water replenishment operation;

[0053] The water flow entering the two water injection tanks 11 can be discharged through the drainage pipes 13 at the front and rear ends and enter the interior of the No. 2 three-way valve 14. At this time, the bottom ends of the two No. 2 three-way valves 14 can simultaneously discharge the water flow and inject the water flow into the interior of the inner ring 4 and the outer ring 5 respectively, completing the water injection operation to conduct a water seepage experiment. At the same time, since the bottom ends of the two water injection tanks 11 are connected with a connecting pipe 12, the two water injection tanks 11 are actually connected to each other. At this time, the liquid level heights of the two water injection tanks 11 will always remain consistent, ensuring that the water injection heights inside the inner ring 4 and the outer ring 5 are the same, ensuring the accuracy of the water seepage experiment;

[0054] When the water flow inside the two water injection tanks 11 is exhausted, the buoyancy of the liquid surface causes the float plate 15 to drop to the lowest point. At this time, the touch counter 20 at the bottom of the float plate 15 contacts the bottom end of the inner cavity of the water injection tank 11, completing a counting process, and the electromagnetic drain valve 193 can be automatically opened at this time. At this time, the water flow inside the water storage tank 7 can be introduced into the interior of the water injection tank 11 through the No. 1 three-way valve 9 and the water pipe 10, the water collecting tank 191 and the electromagnetic drain valve 193 in sequence to complete the automatic water replenishment process and the automatic water replenishment operation;

[0055] And during the water injection process, as the liquid level inside the water injection tank 11 rises, the buoyancy increases accordingly, and the two floating plates 15 rise synchronously, and drive the extension rod 16 to move upward until the movable plate 181 is driven to move upward first. At this time, the distance between the movable plate 181 and the transverse guide rail 17 is shortened, and the two connecting rods 184 are driven to deflect in the direction away from the middle. At this time, the two guide blocks 185 are subjected to thrust, which drives the two sealing plates 194 away from each other. When the sealing plate 194 is displaced to the leftmost position, the top of the water collecting box 191 can be completely sealed, and the injection process of the water flow of the water injection tank 11 is automatically cut off. When the sealing plate 194 is displaced to the leftmost position, the valve of the electromagnetic drain valve 193 can be automatically closed to complete the automatic cut-off process when the water flow is full.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
