Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy projects, in particular to an anti-seepage structure for a water conservancy dam. Background Art

[0002] Water conservancy projects are a general term for various engineering projects built to control, utilize, and protect surface and underground water resources and the environment, and to prevent water disasters. During river management, dams are constructed on both sides of the river. Dams are equipped with gates, which are key flow control devices in water conservancy projects. Their functions include regulating water levels, controlling flow, flood control, power generation, shipping, and water supply, and are crucial to ensuring dam safety and achieving comprehensive benefits.

[0003] In existing technology, dam gates are opened during flood season to release floodwater, lowering the reservoir water level and alleviating flood pressure. During dry season, the gates are closed to store water and raise the upstream water level to ensure water supply or power generation. Existing gates are typically sealed with rubber. However, due to the frequent opening and closing of the gates, the rubber becomes thinner over time, potentially creating gaps between the rubber and the gates. This can lead to water seepage in the dam, making it difficult to use and requiring timely replacement of the rubber, which increases staff workload and costs. Summary of the Invention

[0004] The purpose of the present invention is to provide a water conservancy dam anti-seepage structure to solve the technical problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0008] Preferably, the top end of the bidirectional threaded rod extends to the upper surface of the connecting rod and is fixedly connected to a second gear, one side of the second gear is engaged with a first gear located between the driven gear and the rubber block, a notch is provided on the surface of the first gear, the first gear is fixedly installed on the outer wall of the top end of the fixed block, and the fixed shaft is inserted into the axis of the first gear.

[0009] Preferably, the upper and lower ends of the rubber block are fixedly connected to push blocks, and the opposite sides of the two groups of connecting rods are fixedly connected to connecting blocks that are in contact with the push blocks.

[0010] Preferably, a fixing rod is fixedly connected to one end of the two groups of connecting rods away from the rubber block, a limiting block is fixedly connected to one side surface of the fixing rod, and a limiting groove is formed at one end of the threaded block away from the cleaning block to contact the limiting block.

[0011] Preferably, three groups of scrapers that fit tightly against the surface of the rubber block are fixedly connected to the side of the cleaning block away from the threaded block, and brushes are installed between the three groups of scrapers.

[0012] Preferably, a mounting block is fixedly connected to the surface of the threaded block away from the limiting groove, an arc groove is provided on the surface of the mounting block, one side of the cleaning block is slidably connected to the inner wall of the arc groove through a shaft, and the scraper is in contact with the rubber block.

[0013] Preferably, a magnetic strip is fixedly connected to the front surface of the fixed block, and a positive magnetic block is fixedly connected to one end of the cleaning block, and the magnetic strip and the positive magnetic block are arranged opposite to each other.

[0014] Preferably, a base is fixedly connected between the two groups of gate piers and on the front surface of the gate plate, two groups of sealing grooves are opened on the upper surface of the base, and two groups of sealing strips matching the sealing grooves are symmetrically fixedly connected to the bottom end of the horizontal part of the L-shaped mounting plate.

[0015] In summary, the present invention mainly has the following beneficial effects:

[0016] 1. The present invention can seal both sides of the gate plate by fitting one side of the rubber block to the gate pier. When the rubber block is worn out after long-term use, resulting in a reduction in thickness, the active gear can drive the driven gear to rotate. Under the transmission action of the driven gear, the rubber block can be driven to rotate around the hinged fixed axis in the direction of the gate pier to adjust the initial angle, so that the worn rubber block can continue to cling to the surface of the gate pier, continue to maintain the sealing performance of the gate plate, and effectively reduce water seepage. The above method does not require manual disassembly and replacement of worn rubber blocks. The compensation function of the rubber block reduces the workload of the staff and avoids material damage caused by frequent replacement of rubber blocks to a certain extent, improving the overall practicality while reducing the cost of use. The present invention is different from the traditional sealing process. When wear occurs, it only needs to adjust the angle of the rubber block to compensate, and when it is subjected to water pressure, it can be forced to cling to the joints of the gate plate, effectively improving the basic sealing effect.

[0017] 2. After the gate is sealed by the rubber block, the present invention drives the rubber block to rotate inward when the gate is opened to release water. When the rubber block and the gate are in a vertical state, the scraper on the cleaning block just fits tightly with the surface of the rubber block. As the rubber block continues to rotate inward, the bidirectional threaded rod is driven to rotate synchronously under the action of the second gear. At this time, the cleaning block moves to both ends at the same time under the drive of the threaded block, and then uses the scraper and brush to clean the surface of the rubber block, effectively removing attached impurities such as mud and sand, avoiding abnormal wear of the sealing surface caused by the embedding of mud and sand to a certain extent, and improving the service life of the rubber block. At the same time, the cleaning block can reciprocate under the action of the magnetic strip and the positive magnetic block when moving, further enhancing the cleaning effect. Moreover, since the scraper on the cleaning block adopts a shape that fits the rubber block, it can ensure good contact pressure with the surface of the rubber block during movement, thereby realizing refined cleaning operations.

[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0030] The following describes an embodiment of the present invention based on its overall structure.

[0031] The embodiment of the present invention provides a water conservancy dam anti-seepage structure, such as Figures 1-10 As shown, it includes a gate plate 1, with gate piers 11 at both ends of the gate plate 1, and an L-shaped mounting plate 3 is installed on the front surface of the gate plate 1, through which the sealing component and the cleaning component can be installed;

[0032] Exemplarily, a fixing block 32 is fixedly connected to the front surface of each end of the L-shaped mounting plate 3. A sealing assembly is provided on the side of the fixing block 32 away from the L-shaped mounting plate 3. The sealing assembly includes a rubber block 41 for sealing the gate plate 1. When in a sealed state, the rubber block 41 is arranged at an angle relative to the gate plate 1 (inclined from the gate plate 1 toward the gate pier 11, i.e., inclined from the inside to the outside). The inclined rubber block 41 can seal the contact position between the gate plate 1 and the gate pier 11 to prevent water seepage.

[0033] Exemplarily, a cleaning assembly is provided on one side of the rubber block 41, and the cleaning assembly includes a cleaning block 58 for cleaning the rubber block 41. Both ends of the rubber block 41 are connected to connecting rods 51 through torsion springs. A bidirectional threaded rod 52 located on one side of the rubber block 41 is rotatably connected between the two sets of connecting rods 51. Two sets of threaded blocks 55 are threadedly connected to the outer wall of the bidirectional threaded rod 52, and one end of the two sets of threaded blocks 55 is slidably connected to the cleaning block 58; the bidirectional threaded rod 52 drives the threaded block 55 to move, and then the surface of the rubber block 41 is cleaned by the cleaning block 58.

[0034] See Figure 3-Figure 6 It can be seen that the axis of the rubber block 41 is fixedly connected to a driven gear 43 through a fixed shaft, and a driving gear 44 is engaged with one side of the driven gear 43. The driving gear 44 is driven by a motor, and the motor is installed at the top of the inner wall of the fixed block 32. The bottom end of the rubber block 41 is rotatably connected to the L-shaped mounting plate 3. The driving gear 44 is driven by the motor to rotate, and the driving gear 44 can drive the driven gear 43 to rotate. The driven gear 43 cooperates with the fixed shaft to drive the rubber block 41 to rotate.

[0035] See Figure 3-Figure 6 It can be seen that the top end of the bidirectional threaded rod 52 extends to the upper surface of the connecting rod 51 and is fixedly connected to the second gear 53. One side of the second gear 53 is engaged with the first gear 42 located between the driven gear 43 and the rubber block 41. The rubber block 41 rotates under the drive of the driven gear 43. The rubber block 41 cooperates with the connecting rod 51 to drive the bidirectional threaded rod 52 and the second gear 53 to rotate simultaneously.

[0036] For example, a notch is provided on the surface of the first gear 42. When the rubber block 41 rotates inward until the rubber block 41 is perpendicular to the gate plate 1, the second gear 53 will not mesh with the first gear 42 due to the notch provided on the first gear 42, and thus cannot be driven to rotate.

[0037] See Figure 6 and Figure 7 It can be seen that the upper and lower ends of the rubber block 41 are fixedly connected to the push blocks 411, and the opposite sides of the two sets of connecting rods 51 are fixedly connected to the connecting blocks 511 in contact with the push blocks 411. Through the mutual cooperation of the push blocks 411 and the connecting blocks 511, when the rubber block 41 rotates inwardly to be perpendicular to the L-shaped mounting plate 3 (i.e., the gate plate 1), the second gear 53 just engages with the first gear 42. At this time, the push block 411 is in contact with the connecting block 511. When the rubber block 41 continues to rotate inwardly, under the action of the push block 411 and the connecting block 511, the connecting rod 51 is driven to rotate. At this time, the bidirectional threaded rod 52 also rotates under the drive of the second gear 53, which can drive the cleaning block 58 to move.

[0038] See Figure 7-10It can be seen that a fixing rod 54 is fixedly connected to the end of the two sets of connecting rods 51 away from the rubber block 41, and a limiting block 541 is fixedly connected to the surface of one side of the fixing rod 54. A limiting groove 551 that contacts the limiting block 541 is provided at the end of the threaded block 55 away from the cleaning block 58. Through the mutual cooperation between the limiting block 541 and the limiting groove 551, the moving direction of the threaded block 55 is limited, ensuring that the bidirectional threaded rod 52 drives the threaded block 55 to move along a fixed track.

[0039] See Figure 9 and Figure 10 It can be seen that three groups of scrapers 581 that fit tightly to the surface of the rubber block 41 are fixedly connected to the side of the cleaning block 58 away from the threaded block 55. Brushes 582 are installed between the three groups of scrapers 581. The scrapers 581 are used to clean the mud and impurities on the surface of the rubber block 41. At the same time, the rubber block 41 can be further cleaned in conjunction with the brushes 582.

[0040] See Figure 9 It can be seen that the surface of the threaded block 55 away from the limiting groove 551 is fixedly connected to the mounting block 56, and an arc groove 57 is opened on the surface of the mounting block 56. One side of the cleaning block 58 is slidably connected to the inner wall of the arc groove 57 through an axis, and the scraper 581 is in contact with the rubber block 41.

[0041] See Figure 10 It can be seen that the front surface of the fixed block 32 is fixedly connected to the magnetic strip 33, and one end of the cleaning block 58 is fixedly connected to the positive magnetic block 59. The magnetic strip 33 and the positive magnetic block 59 are arranged opposite to each other, and the magnetic strip 33 is staggered with positive and negative magnetic blocks. The magnetic strip 33 and the positive magnetic block 59 drive the cleaning block 58 to reciprocate through the principle of like poles repelling and opposite poles attracting. When the cleaning block 58 moves vertically, under the principle of like poles repelling and opposite poles attracting, the cleaning block 58 is intermittently attracted and repelled by the magnetic strip 33 during the movement, driving the cleaning block 58 to move back and forth on the inner wall of the arc groove 57, further cleaning the surface of the rubber block 41, and improving the cleaning effect of the rubber block 41.

[0042] See Figure 2 and Figure 3 It can be seen that a base 2 is fixedly connected between the two groups of gate piers 11 and on the front surface of the gate plate 1. Two groups of sealing grooves 21 are provided on the upper surface of the base 2. Two groups of sealing strips 31 matching the sealing grooves 21 are symmetrically fixedly connected to the bottom end of the horizontal part of the L-shaped mounting plate 3. Through the mutual cooperation of the sealing strips 31 and the sealing grooves 21, the contact position between the L-shaped mounting plate 3 and the base 2 can be sealed to prevent water seepage.

[0043] The working principle of the present invention is as follows: when the gate plate 1 is closed, the bottom end of the L-shaped mounting plate 3 contacts the base 2, and the bottom end of the gate plate 1 can be sealed by snapping the sealing strip 31 to the inner wall of the sealing groove 21. At the same time, the contact position between the gate plate 1 and the gate pier 11 is sealed by two groups of rubber blocks 41 to prevent water seepage. At this time, the rubber blocks 41 and the gate plate 1 are arranged at an angle; when the rubber blocks 41 are worn and thinned after long-term use, the motor drives the driving gear 44 to rotate, and the driving gear 44 drives the driven gear 43 to rotate. The driven gear 43 cooperates with the fixed shaft to drive the rubber block 41 to rotate toward the gate pier 11, adjusting its use angle so that the rubber block 41 can continue to seal the gate plate 1. Moreover, since the rubber block 41 is arranged at an angle, when the rubber block 41 is worn, the angle of the rubber block 41 is adjusted to compensate, so that the contact position between the gate plate 1 and the gate pier 11 can continue to be sealed to prevent water seepage.

[0044] Furthermore, when the gate 1 is opened, the rubber block 41 is driven to rotate inward by the motor in conjunction with the driven gear 43. When the rubber block 41 and the L-shaped mounting plate 3 are in a vertical state, the scraper 581 on the cleaning block 58 is just in close contact with the outer wall of the rubber block 41. When the rubber block 41 continues to rotate inward, the push block 411 cooperates with the connecting block 511 to drive the connecting rod 51 to rotate. The connecting rod 51 drives the bidirectional threaded rod 52 and the rubber block 41 to rotate at the same time. When the bidirectional threaded rod 52 rotates, the bidirectional threaded rod 52 is driven to rotate by itself through the mutual cooperation of the second gear 53 and the first gear 42. Under the action of the bidirectional threaded rod 52, the two sets of threaded blocks 51 are driven. 5 moves toward both ends. At this time, the cleaning block 58 is driven to move by the action of the threaded block 55. The cleaning block 58 cooperates with the scraper 581 to clean the surface of the rubber block 41. At the same time, the rubber block 41 can be cleaned by cooperating with the brush 582. When the scraper 581 and the brush 582 are cleaning, the cleaning block 58 can move back and forth on the inner wall of the arc groove 57 under the mutual cooperation of the positive magnetic block 59 and the magnetic strip 33, further cleaning the rubber block 41, preventing abnormal wear caused by mud and sand embedded in the surface of the rubber block 41, and improving the service life of the rubber block 41. The contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
