Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering monitoring instruments, specifically an automatic monitoring device for seepage in dams. Background Technology

[0002] The working condition of dam seepage is crucial to the safe operation of the dam.

[0003] In practice, the traditional method is to drill a small-diameter well at intervals along the cross-section of the dam, install a piezometer inside, and then measure the water pressure and seepage pressure inside the piezometer to obtain actual measurement data. Larger dams are equipped with observation corridors, and the aforementioned piezometers are installed in the observation corridors for technicians to observe.

[0004] Traditional piezometers are lowered into the piezometer tube via a cable, but the depth of descent cannot be controlled. Removing the piezometer from the tube usually involves pulling the cable, which can easily damage the cable or loosen the terminals, altering the piezometer's elevation and affecting the accuracy of the measurement data. Furthermore, in the on-site environment of a dam, it is inconvenient to adjust the cable length inside the piezometer tube; the entire tube must be replaced, which is time-consuming, labor-intensive, and economically wasteful. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an automatic monitoring device for seepage in dams.

[0006] An automatic seepage monitoring device for dams includes a seepage pipe and a piezometer installed inside the seepage pipe. A transmission cable is installed on the top of the piezometer, and a conduit is sleeved around the transmission cable. The lower end of the conduit is fixedly connected to the top of the piezometer, and the upper end of the conduit extends above the seepage pipe. A lifting device for adjusting the height of the piezometer through the conduit is installed on the top of the seepage pipe, and a drive device for rotating the lifting device is installed on one side of the top of the seepage pipe.

[0007] Furthermore, the lifting device includes vertical plates symmetrically arranged on the top of the piezometer. Two mounting plates are fixedly installed on the side of each vertical plate that is close to each other. A lifting wheel is rotatably arranged between the two mounting plates via a rotating shaft. A lifting wheel rubber sleeve is fixedly installed on the outside of the lifting wheel. Multiple lifting wheel rubber sleeve synchronous grooves are evenly arranged on the lifting wheel rubber sleeve. The two lifting wheels are connected by meshing through the lifting wheel rubber sleeve synchronous grooves. A clamping groove is transversely opened in the middle of the lifting wheel rubber sleeve synchronous groove. The conduit passes through the joint of the two clamping grooves and is in close contact with the clamping groove.

[0008] Furthermore, the driving device includes a motor, a fixed base is fixedly installed on one side of the top of the piezometer, the motor is fixedly installed on the top of the fixed base, a drive wheel is fixedly installed at the output end of the motor, a drive wheel rubber sleeve is fixedly installed on the outside of the drive wheel, a plurality of drive wheel rubber sleeve synchronization grooves are evenly arranged on the drive wheel rubber sleeve, a drive hole is opened on the upright plate near the motor, the drive wheel passes through the drive hole and is engaged with the lifting wheel near the motor through the drive wheel rubber sleeve synchronization groove and the lifting wheel rubber sleeve synchronization groove.

[0009] In summary, this utility model has the following beneficial effects:

[0010] This invention relates to a piezometer that is lowered into a seepage pipe via a conduit. The conduit, fitted over the transmission cable, provides protection for the cable. Lowering or retrieving the piezometer is achieved by a drive device that moves a lifting mechanism, causing the conduit to move downwards or upwards. This eliminates the need to pull the transmission cable, ensuring the accuracy of the measurement data and extending the service life of the automatic seepage monitoring device for dams. The conduit is equipped with graduations on the outside, allowing the determination of the piezometer's lowering depth. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] like Figure 1-3 As shown, an automatic seepage monitoring device for a dam includes a seepage pipe 1 and a piezometer 2 installed inside the seepage pipe 1. A transmission cable 4 is installed on the top of the piezometer 2, and a conduit 3 is sleeved on the outside of the transmission cable 4. The lower end of the conduit 3 is fixedly connected to the top of the piezometer 2, and the upper end of the conduit 3 extends above the seepage pipe 1. A lifting device is installed on the top of the seepage pipe 1 to adjust the height of the piezometer 2 through the conduit 3. A drive device for driving the lifting device to rotate is installed on one side of the top of the seepage pipe 1.

[0019] In this embodiment, the piezometer 2 is lowered into the piezometer tube 1 through the conduit 3. The conduit 3 is sleeved on the outside of the transmission cable 4 to protect the transmission cable 4. When lowering or removing the piezometer 2, the lifting device is driven by the drive device to move the conduit 3 downward or upward, thus lowering or removing the piezometer 2 without lifting the transmission cable 4, ensuring the accuracy of the measurement data and extending the service life of the automatic seepage monitoring device for the dam. Preferably, the conduit 3 is provided with scale lines on the outside, which can be used to determine the lowering depth of the piezometer 2.

[0020] The lifting device includes vertical plates 5 symmetrically arranged on the top of the piezometer 2. Two mounting plates 6 are fixedly arranged on the side of the two vertical plates 5 that are close to each other. A lifting wheel 8 is rotatably arranged between the two mounting plates 6 through a rotating shaft 7. A lifting wheel rubber sleeve 9 is fixedly arranged on the outside of the lifting wheel 8. Multiple lifting wheel rubber sleeve synchronous grooves 10 are evenly arranged on the lifting wheel rubber sleeve 9. The two lifting wheels 8 are connected by meshing through the lifting wheel rubber sleeve synchronous grooves 10. A clamping groove 11 is opened laterally in the middle of the lifting wheel rubber sleeve synchronous groove 10. The cable tube 3 passes through the joint of the two clamping grooves 11 and is in close contact with the clamping groove 11.

[0021] In this embodiment, the conduit 3 is disposed at the junction of the two clamping grooves 11. The rubber clamping grooves 11 can provide sufficient clamping force and friction. After the two clamping grooves 11 clamp the conduit 3, the conduit 3 cannot slide down.

[0022] When it is necessary to lower or remove the piezometer 2, the two lifting wheels 8 are controlled by the drive device to rotate in opposite directions at the same speed along the rotating shaft 7 under the action of the synchronous groove 10 of the rubber sleeve of the lifting wheel. The clamping grooves 11 on the rubber sleeves 9 of the two lifting wheels cooperate with each other to drive the threading tube 3 to move downward or upward, so that the piezometer 2 can be lowered or removed.

[0023] The driving device includes a motor 13. A fixed base 12 is fixedly installed on one side of the top of the piezometer 2. The motor 13 is fixedly installed on the top of the fixed base 12. A drive wheel 14 is fixedly installed at the output end of the motor 13. A drive wheel rubber sleeve 15 is fixedly installed on the outside of the drive wheel 14. Multiple drive wheel rubber sleeve synchronization grooves 16 are evenly arranged on the drive wheel rubber sleeve 15. A drive hole 17 is opened on the upright plate 5 near the motor 13. The drive wheel 14 passes through the drive hole 17 and is engaged with the lifting wheel 8 near the motor 13 through the drive wheel rubber sleeve synchronization groove 16 and the lifting wheel rubber sleeve synchronization groove 10.

[0024] In this embodiment, the rotation of the output shaft of the motor 13 drives the drive wheel 14 to rotate. The drive wheel 14 drives the lifting wheel 8 on the side closer to the motor 13 to rotate in the same speed and in the opposite direction through the synchronous groove 16 of the drive wheel rubber sleeve and the synchronous groove 10 of the lifting wheel rubber sleeve. The synchronous groove 10 of the lifting wheel rubber sleeve on the side closer to the motor 13 drives the lifting wheel 8 on the side away from the motor 13 to rotate in the same speed and in the opposite direction. The clamping grooves 11 on the two lifting wheel rubber sleeves 9 cooperate with each other to drive the conduit 3 to move downward or upward.

[0025] When the piezometer 2 is lowered, the output shaft of the motor 13 drives the drive wheel 14 to rotate forward. The drive wheel 14 drives the lifting wheel 8 on the side closer to the motor 13 to rotate in the same direction at the same speed through the synchronous groove 16 of the drive wheel rubber sleeve and the synchronous groove 10 of the lifting wheel rubber sleeve. The synchronous groove 10 of the lifting wheel rubber sleeve on the side closer to the motor 13 drives the lifting wheel 8 on the side away from the motor 13 to rotate forward at the same speed. The clamping grooves 11 on the two lifting wheel rubber sleeves 9 cooperate with each other to drive the threading tube 3 to descend, thus lowering the piezometer 2.

[0026] When the piezometer 2 is removed, the output shaft of the motor 13 drives the drive wheel 14 to rotate in reverse. The drive wheel 14 drives the lifting wheel 8 on the side closer to the motor 13 to rotate forward at the same speed through the synchronous groove 16 of the drive wheel rubber sleeve and the synchronous groove 10 of the lifting wheel rubber sleeve. The synchronous groove 10 of the lifting wheel rubber sleeve on the side closer to the motor 13 drives the lifting wheel 8 on the side away from the motor 13 to rotate in reverse at the same speed. The clamping grooves 11 on the two lifting wheel rubber sleeves 9 cooperate with each other to drive the threading tube 3 to rise, so that the piezometer 2 can be removed.
