Description

Technical Field

[0001] The present invention relates to the technical field of seepage pressure monitoring, and more particularly to a device for monitoring seepage pressure of a dam. Background Art

[0002] In water conservancy projects, when the dam is in operation, the water level difference between upstream and downstream will generate seepage pressure. If the seepage pressure is too large and unevenly distributed, it will cause seepage damage to the dam body or dam foundation, such as pipe burst and soil flow. The monitoring device can grasp the seepage pressure changes in real time. Once the seepage pressure is found to be abnormally high, timely measures can be taken, such as lowering the reservoir water level and conducting backfiltration and drainage to prevent the occurrence of seepage damage and ensure the structural safety of the dam. Therefore, it is particularly important to monitor the seepage pressure data of the dam with a monitoring device.

[0003] Patent publication number CN203811318U discloses a fiber Bragg grating pressure sensing device for dam seepage pressure monitoring based on a diaphragm-type packaging structure. This technology splits an optical signal coupled by a fiber coupler into n paths, each of which is sent to n pressure sensing units. The fiber coupler collects the optical signals reflected from the n pressure sensing units, and the optical signal output of the fiber coupler is connected to the second optical signal input of a circulator, which in turn is connected to the optical signal input of an optical spectrum analyzer. The pressure sensing unit comprises a pressure sensor and a flat diaphragm. This technology is suitable for a pressure monitoring system. However, this patent has the following drawbacks.

[0004] When monitoring the seepage pressure of dams, due to the large number of seepage pressure points, each point requires a single pressure sensor to reflect the seepage pressure value, which brings many problems. On the one hand, a single pressure sensor is difficult to synchronously monitor the seepage pressure exceeding the threshold at multiple points above and below. On the other hand, multiple points correspond to multiple pressure sensors, which greatly increases the production and use costs. At the same time, the subsequent maintenance work is also more complicated due to the large number of sensors, and the maintenance costs increase accordingly. Not only is the monitoring range small, but the production, use and maintenance costs of the dam seepage pressure monitoring device are also greatly increased. Summary of the Invention

[0007] In a preferred embodiment, the bottom inclined surface of the L-shaped inclined bar and the bottom inclined surface of the socketed inclined bar are arranged in parallel; Multiple said lower monitoring blocks and multiple upper monitoring blocks are all arranged in a circumferentially equidistant distribution.

[0008] In a preferred embodiment, a guiding and limiting assembly is installed at one end of the convex bar guide post.

The other end of the convex bar guide post is fixedly connected with a support bar; The linkage bar is fixedly connected to the outer wall of the top end of the support bar.

[0009] In a preferred embodiment, the vertical cross-sectional shape of the linkage bar is L-shaped, and the cross-sectional area of the guiding sleeve is larger than the cross-sectional area of the limiting sleeve.

[0010] In a preferred embodiment, the cross-sectional area of the sleeve bar is smaller than the cross-sectional area of the support sleeve, and the vertical cross-sectional shape of the fixed frame is L-shaped.

[0011] In a preferred embodiment, the outer wall of the L-shaped oblique strip and the inner wall of the support sleeve are both smooth surfaces, and the sleeve strip is made of nylon.

[0013] In a preferred embodiment, a mounting block is fixedly connected to the upper surface of the mounting sleeve near its edge line, and a through hole with a circular vertical cross-section is provided inside the mounting block.

[0014] The technical effects and advantages of the present invention are as follows: 1. The present invention has multi-point monitoring capability through the lower linkage monitoring component. Multiple lower monitoring blocks are distributed at different positions in the lower part, which can comprehensively and accurately monitor the seepage pressure conditions in various areas of the water conservancy project dam. At the same time, when any of the lower monitoring blocks is impacted by the seepage water body, the upper inclined surface of the inclined push bar will be squeezed on the lower inclined surface of the inclined pressure bar, and the pressure column will be squeezed on the pressure probe. The pressure probe can quickly bear the force to generate the seepage pressure value. The abnormal seepage pressure problem in multiple lower monitoring block areas can be monitored by a single pressure probe. This design avoids the need to equip each monitoring point with a single pressure probe, significantly reduces the purchase quantity of pressure probes, and thus reduces the cost investment in the production link. At the same time, during the use and maintenance process, the manpower and material costs are greatly reduced due to the reduction in the number of pressure probes. Not only is the monitoring range wider, but the production, use and maintenance costs of the dam seepage pressure monitoring device are also greatly reduced.

[0015] 2. The present invention adopts an upper linkage monitoring component, and multiple socketed oblique bars are distributed at different positions on the upper part of the dam of the water conservancy project. The upper seepage pressure can be monitored at multiple points. These areas can be monitored simultaneously by a single pressure probe. When any upper monitoring block is impacted by the seepage water body, the L-shaped oblique bar is moved upward by the socketed oblique bar, so that the pressure probe senses the seepage pressure value. This design greatly expands the monitoring range of a single pressure probe, and there is no need to equip each monitoring point with a single pressure probe, which significantly reduces the number of pressure probes used, thereby reducing costs in the production process. In subsequent use and maintenance, the small number of pressure probes greatly reduces the manpower and material resources investment, achieving the dual advantages of efficient monitoring and cost control.

[0016] 3. In the present invention, through the guiding and limiting component, after the lower inclined surface of the inclined pressure bar receives the extrusion force of the inclined pushing bar, the inclined pressure bar drives the limiting sleeve to move upward. The inclined pressure bar guides and limits the upward movement along the inner wall of the guiding sleeve. At the same time, the socketed inclined bar guides and moves backward along the outer wall of the guiding rod. The L-shaped inclined bar begins to guide and limit the upward movement along the inner wall of the support sleeve. At the same time, the L-shaped inclined bar drives the sleeve bar to move upward. This design ensures that the inclined pushing bar, the inclined pressure bar, the socketed inclined bar, and the L-shaped inclined bar move along the specified path, with precise and stable movement, effectively improving the overall reliability and monitoring accuracy of the device, and ensuring that stable seepage pressure monitoring can be carried out on multiple lower monitoring blocks and multiple upper monitoring blocks through a single pressure probe.

[0017] In summary, through a single pressure probe, seepage pressure anomalies in multiple lower monitoring block areas can be detected, and at the same time, seepage pressure anomalies in multiple upper monitoring block areas can be detected by a single pressure probe, greatly expanding the monitoring range of a single pressure probe. Moreover, there is no need to individually equip sensors for each monitoring point, thereby reducing costs in the production process. During subsequent use, maintenance, and repair, the maintenance and repair costs are also reduced, achieving the dual advantages of efficient monitoring and cost control.

Detailed implementation mode

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] As Figure 1 - Figure 8 shown, a monitoring device for seepage pressure of a sluice dam is provided with a lower linkage monitoring component, an upper linkage monitoring component and a guiding and limiting component. The setting of each component can monitor the seepage pressure abnormality problems existing in multiple lower monitoring block 5 areas through a single pressure probe 1. At the same time, a single pressure probe 1 can monitor the seepage pressure abnormality problems existing in multiple upper monitoring block 9 areas. The specific structural settings of each component are as follows.

[0029] In this embodiment, as Figure 1 - Figure 4 shown, the outer wall of the pressure probe 1 is fixedly connected with a mounting sleeve plate 13. The sensing end of the pressure probe 1 is provided with a lower linkage monitoring component. The lower linkage monitoring component includes: a plurality of pressing columns 2, all of which are in contact connection with the sensing end of the pressure probe 1. The bottom end of each pressing column 2 is fixedly connected with an inclined pressure strip 3; an inclined push strip 4, which is located on the lower inclined surface of the inclined pressure strip 3. The upper inclined surface of the inclined push strip 4 is slidably connected with the lower inclined surface of the inclined pressure strip 3. The inclined push strip 4 is used to squeeze the inclined pressure strip 3 to move upward. The bottom end of the inclined push strip 4 is fixedly connected with a lower monitoring block 5, and a convex strip guide post 6 is slidably connected to the inner wall of the inclined push strip 4; an upper linkage monitoring component, which is located between two adjacent inclined pressure strips 3. The upper linkage monitoring component includes: an L-shaped inclined strip 7, which is located between two adjacent inclined pressure strips 3. The top end of the L-shaped inclined strip 7 is in contact connection with the output end of the pressure probe 1. The inclined bottom surface of the L-shaped inclined strip 7 is slidably connected with a socketed inclined strip 8.

[0030] The socketed inclined bar 8 slides along the inner wall of the mounting sleeve plate 13 for squeezing the L-shaped inclined bar 7 to move upward; the upper monitoring block 9 is fixedly connected to the top end of the socketed inclined bar 8. The upper inclined surface of the inclined push bar 4 is parallel to the lower inclined surface of the inclined pressure bar 3, and the outer walls of both the inclined push bar 4 and the inclined pressure bar 3 are smooth surfaces. The bottom inclined surface of the L-shaped inclined bar 7 is parallel to the bottom inclined surface of the socketed inclined bar 8; a plurality of lower monitoring blocks 5 and a plurality of upper monitoring blocks 9 are all arranged in a circumferential equidistant distribution, so that when any one of the plurality of lower monitoring blocks 5 at the lower part is impacted by seepage pressure water, the inclined pressure bar 3 will move upward due to the force applied through the inclined push bar 4, and the pressure column 2 will transmit the force to the pressure probe 1 for seepage pressure numerical monitoring. When any one of the plurality of upper monitoring blocks 9 at the upper part is impacted, the socketed inclined bar 8 will provide a squeezing force to the L-shaped inclined bar 7, realizing the upward movement of the L-shaped inclined bar 7 to transmit the force to the pressure probe 1. Multi-point monitoring of the seepage pressure of the sluice dam can be carried out at different positions in the lower and upper parts respectively, comprehensively covering the key areas of the sluice dam, accurately grasping the seepage pressure condition, and moreover, the seepage pressure abnormal monitoring of multiple monitoring areas can be realized with one pressure probe 1, reducing the number of pressure probes 1 used and lowering the production, use and later maintenance costs.

[0031] In this embodiment, as Figure 2 - Figure 7 shown, a guiding and limiting assembly is installed at one end of the ribbed guide post 6. The guiding and limiting assembly includes: a limiting block 10 fixedly connected to one end of the ribbed guide post 6, and a support bar 11 fixedly connected to the other end of the ribbed guide post 6; a linkage bar 12 fixedly connected to the outer wall at the top end of the support bar 11, the top end of the linkage bar 12 is fixedly connected to the lower surface of the mounting sleeve plate 13, a guiding sleeve 14 is fixedly installed at the bottom end of the linkage bar 12, and the guiding sleeve 14 is slidably connected to the inclined pressure bar 3. A limiting sleeve 15 abuts against the upper surface of the guiding sleeve 14, and the limiting sleeve 15 is fixedly connected to the outer wall of the inclined pressure bar 3; a guiding rod 16 is slidably inserted into the socketed inclined bar 8, the guiding rod 16 is fixedly connected to the mounting sleeve plate 13, a sleeve bar 17 is fixedly connected to the outer wall of the L-shaped inclined bar 7, and a support sleeve 18 abuts against the lower surface of the sleeve bar 17; a fixing frame 19 is fixedly connected to the outer wall of the support sleeve 18, and the top end of the fixing frame 19 is fixedly connected to the mounting sleeve plate 13.

[0032] The vertical cross-section of the linkage bar 12 is L-shaped, and the cross-sectional area of the guide sleeve 14 is larger than that of the limiting sleeve 15. The cross-sectional area of the sleeve 17 is smaller than that of the support sleeve 18, and the vertical cross-sectional shape of the fixing frame 19 is L-shaped. The outer wall of the L-shaped inclined bar 7 and the inner wall of the support sleeve 18 are both smooth surfaces. The sleeve 17 is made of nylon material to facilitate the support of the linkage bar 12 by the installation sleeve 13. The linkage bar 12 supports the guide sleeve 14, and the guide sleeve 14 provides positional support for the limiting sleeve 15. The guide sleeve 14 also provides vertical guidance and position limitation for the diagonal pressure bar 3. The linkage bar 12 can also support the supporting bar 11. The limit block 10 on the convex bar guide column 6 limits the rear position of the diagonal push bar 4, and the convex bar guide column 6 guides and limits the horizontal movement of the diagonal push bar 4. At the same time, the sleeve plate 13 is installed to support the fixed frame 19, the fixed frame 19 supports the support sleeve 18, the support sleeve 18 supports the sleeve strip 17, and the support sleeve 18 realizes vertical guide limitation for the internal L-shaped oblique strip 7, ensuring that the L-shaped oblique strip 7 moves upward according to the vertical guide limit. The guide limit design of each component can ensure that the relevant components move in the predetermined direction and path when subjected to force, making the force transmission more accurate, thereby improving the accuracy and reliability of seepage pressure monitoring.

[0033] In this embodiment, if Figure 8 As shown, a wireless transceiver 20 is fixedly installed on the upper surface of the pressure probe 1. The wireless transceiver 20 is electrically connected to the pressure probe 1 so that when the osmotic pressure value sensed by the pressure probe 1 exceeds the pressure value set by the wireless transceiver 20, the osmotic pressure value is transmitted to the wireless transceiver 20 through the pressure probe 1 to realize wireless remote monitoring.

[0034] In this embodiment, if Figure 8 As shown, a mounting block 21 is fixedly connected to the upper surface of the mounting sleeve 13 near its edge line. A through hole with a circular vertical cross-section is provided inside the mounting block 21 to facilitate the mounting sleeve 13 to be placed in the detection hole for seepage pressure of the water conservancy project dam. Holes are drilled in the concrete in the detection hole for seepage pressure of the water conservancy project dam, so that the expansion bolts are installed in the mounting block 21 for docking installation. The mounting block 21 provides a firm fixing force for the mounting sleeve 13.

[0035] The working principle of the dam seepage pressure monitoring device of the present invention is as follows: First, when the present invention is installed and used, the mounting sleeve plate 13 is placed into the detection hole position for the seepage pressure of the sluice dam in the water conservancy project. The wireless transceiver 20 and the pressure probe 1 are powered by the municipal wire harness. Then, when the mounting sleeve plate 13 drives the mounting block 21 to move to the internal installation position in the detection hole position for the seepage pressure of the sluice dam in the water conservancy project, holes are drilled in the concrete in the detection hole position for the seepage pressure of the sluice dam in the water conservancy project. In this way, the expansion bolts can be installed into the inside of the mounting block 21, and the mounting block 21 is fixed in the detection hole position for the seepage pressure of the sluice dam in the water conservancy project. The mounting block 21 supports the mounting sleeve plate 13, and the mounting sleeve plate 13 supports the pressure probe 1. Multiple lower monitoring blocks 5 can make multi-point contact on the inner wall of the detection hole position for the seepage pressure of the sluice dam in the water conservancy project at the lower part, while multiple upper monitoring blocks 9 can make multi-point contact on the inner wall of the detection hole position for the seepage pressure of the sluice dam in the water conservancy project at the upper part.

[0036] Secondly, when the present invention conducts guiding and limiting, the mounting sleeve plate 13 supports the linkage bar 12, the linkage bar 12 supports the guide sleeve 14, and the guide sleeve 14 supports and limits the limiting sleeve 15. The inclined pressure bar 3 drives the limiting sleeve 15 to move downward and abut against the upper surface of the guide sleeve 14. At the same time, the guide sleeve 14 can conduct vertical guiding and limiting on the outer wall of the inclined pressure bar 3. The linkage bar 12 supports the support bar 11, the support bar 11 supports the ribbed guide post 6, and the limiting block 10 on the ribbed guide post 6 can limit the rear of the inclined push bar 4. At the same time, the ribbed guide post 6 can conduct guiding and limiting operations for the stable horizontal movement of the inclined push bar 4. At the same time, the mounting sleeve plate 13 supports the fixed frame 19, the fixed frame 19 supports the support sleeve 18, the support sleeve 18 conducts vertical limiting and supporting on the sleeve bar 17, and at the same time, the support sleeve 18 conducts guiding and limiting on the inner wall of the sleeve bar 17 to ensure that the L-shaped inclined bar 7 is guided and limited in the upward direction numerically.

[0037] Then, when the present invention conducts upper and lower linkage monitoring, when one of the multiple lower monitoring blocks 5 is impacted by the seepage pressure water body of the sluice dam in the water conservancy project, the seepage pressure water body is squeezed on one of the lower monitoring blocks 5. The lower monitoring block 5 is stressed and squeezed on the inclined push bar 4. The inclined push bar 4 is stressed and moves backward. The inclined push bar 4 moves backward along the outer wall of the ribbed guide post 6 for guiding and limiting. The inclined surface on the inclined push bar 4 will squeeze on the lower inclined surface of the inclined pressure bar 3. Thus, after the lower inclined surface of the inclined pressure bar 3 receives the extrusion force from the inclined push bar 4, the inclined pressure bar 3 drives the limiting sleeve 15 to move upward. At the same time, the inclined pressure bar 3 moves upward along the inner wall of the guide sleeve 14 for guiding and limiting. In this way, the inclined pressure bar 3 squeezes on the pressure column 2, and the pressure column 2 squeezes on the pressure probe 1.

[0038] The sensing end of the pressure probe 1 can be forced to generate a seepage pressure value. When the seepage pressure value sensed by the pressure probe 1 exceeds the pressure value set by the wireless transceiver 20, the seepage pressure value is transmitted to the wireless transceiver 20 through the pressure probe 1, and the wireless transceiver 20 can wirelessly transmit it to the background computer, so that it can be known that there is an abnormality in the seepage pressure value of the sluice dam of the water conservancy project. In this way, multiple lower monitoring blocks 5 can monitor the seepage pressure of the sluice dam of the water conservancy project at multiple positions in different lower positions. As long as the seepage pressure value of any one of the lower monitoring blocks 5 exceeds the pressure value set by the wireless transceiver 20, it can be immediately known that there is an abnormality in the area monitored by the multiple lower monitoring blocks 5.

[0039] When one of the multiple upper monitoring blocks 9 is impacted by the seepage pressure water body of the sluice dam of the water conservancy project, the upper monitoring block 9 is forced to squeeze the socket slanting bar 8, and the socket slanting bar 8 moves backward along the outer wall of the guide rod 16, and the inclined surface at the bottom of the socket slanting bar 8 begins to squeeze the inclined surface at the bottom of the L-shaped slanting bar 7, so that the socket slanting bar 8 makes the L-shaped slanting bar 7 start to move upward along the inner wall of the support sleeve 18 for guiding and limiting. At the same time, the L-shaped slanting bar 7 drives the sleeve bar 17 to move upward, and the top of the L-shaped slanting bar 7 presses on the sensing end of the pressure probe 1. The sensing end of the pressure probe 1 is forced to be squeezed and senses the seepage pressure value. When the seepage pressure value sensed by the pressure probe 1 exceeds the pressure value set by the wireless transceiver 20, the seepage pressure value is transmitted to the wireless transceiver 20 through the pressure probe 1, and the wireless transceiver 20 wirelessly transmits it to the background computer, so that it can be known that there is an abnormality in the seepage pressure value of the sluice dam of the water conservancy project. Multiple socket slanting bars 8 can monitor the seepage pressure of the sluice dam of the water conservancy project at multiple positions in different upper positions. As long as the seepage pressure value of any one of the lower socket slanting bars 8 exceeds the pressure value set by the wireless transceiver 20, it can be immediately known that there is an abnormality in the area monitored by the multiple socket slanting bars 8. Through a single pressure probe 1, the seepage pressure abnormality problems in the areas of multiple lower monitoring blocks 5 can be monitored, and at the same time, the seepage pressure abnormality problems in the areas of multiple upper monitoring blocks 9 can be monitored.
