Description

Technical Field

[0001] This invention relates to the field of bridge inspection equipment technology, specifically to a new material bridge screening and seepage detection device with a nested telescopic structure. Background Technology

[0002] A bridge generally refers to a structure erected over rivers, lakes, or seas to allow vehicles and pedestrians to pass smoothly. To adapt to the rapidly developing modern transportation industry, the term "bridge" has also come to refer to structures built across mountains, challenging geological conditions, or to meet other transportation needs, making travel more convenient. To ensure bridges can adapt to different geological conditions and climates, the materials used in their construction typically need to be modified accordingly. For example, the proportions of concrete need to be optimized; in areas with varying geological moisture content, concrete in areas with abundant groundwater needs to be impermeable, while in arid regions, moisture retention is crucial.

[0003] After constructing bridges using new materials, it is necessary to screen and test the bridge's impermeability to ensure that the bridge's quality meets safety standards. Existing seepage testing instruments require the following steps: first, selecting testing points on the road surface and cleaning away dust and debris with a broom and fine wire brush; then, marking circles on the cleaned road surface with chalk according to the size of the testing instrument's base; applying a ring of sealant around the base, ensuring the sealant fills the gaps and adheres firmly to the road surface; finally, pressing the assembled seepage testing instrument base firmly onto the sealant ring for expansion and contraction testing. To ensure accuracy, multiple testing points are also required. With existing seepage testing instruments, when applying sealant, personnel need to use a scraper to apply the sealant within the marked circles. Manual application with a scraper is not always even, the application area is difficult to control, and sealant easily spills outside the circles, affecting accuracy. Each point requires cleaning, marking, and applying sealant, which is time-consuming and reduces the efficiency of seepage testing. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a novel material bridge seepage detection device with a nested telescopic structure, comprising a standard ring and a detection mechanism, wherein the detection mechanism includes a top plate fixedly mounted on top of the standard ring via a bracket.

[0005] A sealing mechanism includes a glue storage ring cavity inside a standard ring. The bottom of the standard ring has glue outlet holes that are evenly distributed around its circumference and communicate with the glue storage ring cavity. A movable plate is slidably installed inside the glue storage ring cavity. An arc-shaped plate corresponding to each glue outlet hole is rotatably installed at the bottom of the standard ring. An extrusion assembly is installed on the standard ring to push the movable plate downward and drive the arc-shaped plate to rotate circumferentially. The extrusion assembly is also equipped with a moving component that drives the arc-shaped plate to move away from the central axis of the standard ring when it rotates.

[0006] The top plate is equipped with a telescopic mechanism for pushing the glue cylinder to inject sealing material into the glue storage ring cavity.

[0007] In one possible implementation, the extrusion assembly includes a rotating ring rotatably mounted on the outer ring wall of a standard ring, a drive ring fixedly connected to the top of the rotating ring, a movable ring fixedly connected to the top of the movable plate, the top of the movable ring sliding up and down through to the top of the standard ring, the inner ring wall of the drive ring being threadedly connected to the outer ring wall of the movable ring, and a push handle fixedly connected to the front side of the rotating ring.

[0008] In one possible implementation, the moving component includes guide grooves fixedly connected to both the left and right sides of the outer ring wall of the rotating ring. A lead screw is rotatably mounted inside the guide groove. A movable block is threaded onto the lead screw. The movable block is slidably connected to the guide groove. The bottom of the movable block is fixedly connected to one end of the arc plate away from the central axis of the standard ring. A transmission component is installed on the standard ring to drive the lead screw to rotate when the rotating ring rotates.

[0009] In one possible implementation, a ring groove is formed on the outer ring wall of the standard ring, and the transmission assembly includes a transmission gear ring one fixedly installed inside the ring groove. The end of the lead screw one near the central axis of the standard ring rotates through to the outside of the guide groove and is coaxially fixedly connected to a transmission gear one. The transmission gear one meshes with the bottom of the transmission gear ring one.

[0010] In one possible implementation, the arc-shaped plate is arc-shaped, and a beveled surface is provided on the side of the arc-shaped plate near the central axis of the standard ring. The end of the beveled surface near the central axis of the standard ring is inclined upward, and a retaining ring located inside the arc-shaped plate is detachably installed at the bottom of the standard ring.

[0011] In one possible implementation, the top of the movable ring has a plurality of circumferentially evenly distributed glue injection holes, the glue outlet at the bottom end of the glue tube is threadedly connected to the glue injection holes, and a one-way valve corresponding to each glue injection hole and communicating vertically is installed inside the movable ring. The bottom of the one-way valve passes through the movable ring and the movable plate and communicates with the inside of the glue storage ring cavity.

[0012] In one possible implementation, the telescopic mechanism includes an outer sleeve fixedly installed at the bottom of the top plate and corresponding one-to-one with the glue injection holes. An inner sleeve is slidably installed at the bottom of the outer sleeve, and the inner sleeve is located directly above the glue cylinder. A second lead screw is threaded to the top of the inner sleeve, and the second lead screw is rotatably connected to the outer sleeve. A drive assembly for driving a plurality of second lead screws to rotate is installed on the top plate.

[0013] In one possible implementation, the drive assembly includes a second transmission gear ring rotatably mounted on the top of a top plate. The top end of the second lead screw rotatably extends through the top of the top plate and is fixedly connected to a second transmission gear. Several of the second transmission gears mesh with the outer side of the second transmission gear ring. A drive gear located inside the second transmission gear ring is rotatably mounted on the top of the top plate. The drive gear meshes with the inner side of the second transmission gear ring. A rotating handle is fixedly mounted on the top of the drive gear.

[0014] In one possible implementation, the testing mechanism further includes a glass tube fixedly mounted on a top plate, a valve fixedly mounted on the bottom of the top plate, the top of the valve being connected to the bottom of the glass tube, a connecting pipe fixedly connected between the bottom of the valve and the top of the standard ring, and the bottom of the connecting pipe being connected to the bottom of the standard ring through the inner diameter of the standard ring.

[0015] The beneficial effects of this invention are as follows: 1. By setting a glue storage ring cavity inside the standard ring, during water leakage detection, the rotating push handle drives the rotating ring to rotate, which in turn drives the drive ring to rotate. The drive ring drives the movable ring and movable plate to move downward, causing the movable plate to push the sealing material inside the glue storage ring cavity downward. At this time, the rotating ring drives the arc plate to rotate together, and the arc plate is used to rotate and apply the sealing material, uniformly filling the gap between the standard ring and the bridge surface. There is no need to perform separate marking and glue application, which improves the detection efficiency. When the arc plate rotates, the moving component moves it away from the central axis of the standard ring, which can apply the sealing material layer by layer, improve the density of the sealing material application, and prevent leakage.

[0016] 2. This invention uses a glue cylinder for glue replenishment. When the sealing material in the glue storage ring cavity is used up during multi-point seepage detection, the drive assembly drives the second lead screw to rotate. The second lead screw drives the inner sleeve to move downward and push the glue cylinder, injecting the sealing material in the glue cylinder into the glue storage ring cavity. This allows for timely replenishment of the sealing material in the glue storage ring cavity, facilitating multi-point seepage detection and further improving the detection efficiency of bridge seepage.

Detailed Implementation

[0026] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Please see Figure 1 - Figure 8 A new material bridge screening seepage detection device with a nested telescopic structure includes a standard ring 1 and a weight block 6 placed on the standard ring 1, and also includes a detection mechanism 2, which includes a top plate 21 fixedly installed on the top of the standard ring 1 by a bracket.

[0028] The sealing mechanism 3 includes a glue storage ring cavity 31 inside the standard ring 1. The bottom of the standard ring 1 is evenly provided with glue outlet holes 311 that communicate with the glue storage ring cavity 31. A movable plate 32 is slidably installed inside the glue storage ring cavity 31. An arc-shaped plate 34 corresponding to the glue outlet hole 311 is rotatably installed at the bottom of the standard ring 1. A glue extrusion assembly 33 is installed on the standard ring 1 to push the movable plate 32 downward and drive the arc-shaped plate 34 to rotate circumferentially. A moving assembly 35 is also installed on the glue extrusion assembly 33 to drive the arc-shaped plate 34 to move away from the central axis of the standard ring 1 when it rotates.

[0029] The top plate 21 is equipped with a telescopic mechanism 5 for pushing the glue cylinder 4 to inject the sealing material into the glue storage ring cavity 31.

[0030] In practical use, the standard ring 1 is placed on the part to be tested. The sealing material is stored in the glue storage ring cavity 31. The extrusion assembly 33 pushes the movable plate 32 downward, so that the movable plate 32 squeezes the sealing material downward from the glue outlet 311. At the same time, the extrusion assembly 33 drives the arc plate 34 to rotate, so that the sealing material is evenly applied to the bottom of the standard ring 1. The moving assembly 35 drives the arc plate 34 to move away from the central axis of the standard ring 1 while the arc plate 34 rotates, so that the sealing material can be applied layer by layer. There is no need for separate marking and glue application, which improves the testing efficiency, improves the density of the sealing material application, and prevents leakage.

[0031] When conducting multi-point water seepage testing, after the sealing material in the rubber storage ring cavity 31 is used up, the rubber cylinder 4 is pushed downward by the telescopic mechanism 5 to inject the sealing material in the rubber cylinder 4 into the rubber storage ring cavity 31, so as to replenish the sealing material in time, meet the needs of subsequent multi-point water seepage testing, and further improve the testing efficiency.

[0032] Please see Figure 1 - Figure 3 The extrusion assembly 33 includes a rotating ring 331 rotatably mounted on the outer ring wall of the standard ring 1. A drive ring 332 is fixedly connected to the top of the rotating ring 331. A movable ring 333 is fixedly connected to the top of the movable plate 32. The top of the movable ring 333 slides up and down through to the top of the standard ring 1. The inner ring wall of the drive ring 332 is threadedly connected to the outer ring wall of the movable ring 333. A push handle 334 is fixedly connected to the front side of the rotating ring 331.

[0033] In practical use, when the movable plate 32 needs to be pushed down, the push handle 334 is pushed to drive the rotating ring 331 to rotate counterclockwise. The rotating ring 331 drives the drive ring 332 to rotate, and the drive ring 332 drives the movable ring 333 to move down. The movable ring 333 pushes the movable plate 32 down, so that the movable plate 32 squeezes the sealing material inside the glue storage ring cavity 31 out of the glue outlet 311, which makes it easier to fill the sealing material between the standard ring 1 and the bridge surface.

[0034] Please see Figure 2 - Figure 4 The moving component 35 includes guide grooves 351 that are fixedly connected to both sides of the outer ring wall of the rotating ring 331. A lead screw 352 is rotatably installed inside the guide groove 351. A movable block 353 is threadedly connected to the lead screw 352. The movable block 353 is slidably connected to the guide groove 351. The bottom of the movable block 353 is fixedly connected to the end of the arc plate 34 away from the central axis of the standard ring 1. A transmission component is installed on the standard ring 1 to drive the lead screw 352 to rotate when the rotating ring 331 rotates.

[0035] Please see Figure 3 - Figure 5 The outer ring wall of the standard ring 1 is provided with a ring groove 11. The transmission assembly includes a transmission gear ring 354 fixedly installed inside the ring groove 11. The end of the lead screw 352 near the central axis of the standard ring 1 rotates through to the outside of the guide groove 351 and is coaxially fixedly connected to a transmission gear 355. The transmission gear 355 meshes with the bottom of the transmission gear ring 354.

[0036] In practical use, when the rotating ring 331 rotates counterclockwise, it will drive the guide groove 351 and the arc plate 34 to rotate together. The guide groove 351 drives the lead screw 352 to rotate around the standard ring 1. The transmission gear ring 354 drives the transmission gear 355 and the lead screw 352 to rotate, so that the lead screw 352 drives the movable block 353 to move away from the central axis of the standard ring 1. The movable block 353 drives the arc plate 34 to move away from the central axis of the standard ring 1, so that the arc plate 34 moves in a spiral shape away from the central axis of the standard ring 1. This allows the sealing material to be applied layer by layer from the inside to the outside, so that the sealing material is evenly and densely applied to the bottom of the standard ring 1, avoiding leakage of the sealing material during water seepage detection.

[0037] After the test is completed, by pushing the push handle 334 to drive the rotating ring 331 to rotate clockwise, the lead screw 352 rotates in the opposite direction. At this time, the lead screw 352 will drive the movable block 353 to move towards the central axis of the standard ring 1, so that the arc plate 34 moves in a spiral shape towards the central axis of the standard ring 1, which can scrape off the sealing material layer by layer from the outside to the inside, making it convenient to perform preliminary cleaning of the sealing material at the bottom of the standard ring 1.

[0038] Please see Figure 2 and Figure 4 The arc plate 34 is arc-shaped, and a beveled surface 341 is provided on the side of the arc plate 34 near the central axis of the standard ring 1. The end of the beveled surface 341 near the central axis of the standard ring 1 is inclined upward. A rubber-blocking ring 12 located inside the arc plate 34 is detachably installed at the bottom of the standard ring 1.

[0039] By designing the arc plate 34 as an arc, when the arc plate 34 rotates counterclockwise, the sealing material can gradually move along the outer arc surface of the arc plate 34 towards the central axis of the standard ring 1, which facilitates the application of the sealing material layer by layer. When the arc plate 34 rotates clockwise, the sealing material can move along the inner arc surface of the arc plate 34 away from the central axis of the standard ring 1, which facilitates the scraping off of the sealing material. The beveled surface 341 can form a slope at the edge of the sealing material when applying the sealing material, which increases the support of the sealing material.

[0040] By blocking the sealing material with the sealing ring 12, the sealing material can be prevented from flowing towards the central axis of the standard ring 1, ensuring that the bottom of the standard ring 1 has sufficient testing surface and improving the accuracy of the test.

[0041] Please see Figure 3 and Figure 8 The top of the movable ring 333 has several circumferentially evenly distributed glue injection holes 36. The glue outlet at the bottom of the glue tube 4 is threadedly connected to the glue injection holes 36. The inside of the movable ring 333 is equipped with a one-way valve 37 that corresponds to the glue injection holes 36 and is connected vertically. The sealing material flows from top to bottom along the one-way valve 37. The bottom of the one-way valve 37 passes through the movable ring 333 and the movable plate 32 and is connected to the inside of the glue storage ring cavity 31.

[0042] In practical use, the sealant is replenished by setting the glue cylinder 4. When the sealant in the glue storage ring cavity 31 is used up during multi-point seepage detection, the sealant in the glue cylinder 4 is injected into the glue storage ring cavity 31 by pushing the glue cylinder 4 through the telescopic mechanism 5. This can replenish the sealant in the glue storage ring cavity 31 in a timely manner, which is convenient for multi-point seepage detection and improves the detection efficiency of bridge seepage. The glue cylinder 4 adopts a detachable design. When the sealant in the glue cylinder 4 is used up, the used glue cylinder 4 can be removed and replaced with a new glue cylinder 4, which is convenient for multi-point detection.

[0043] By setting a one-way valve 37 to restrict the flow direction of the sealing material, the sealing material in the glue cylinder 4 can flow into the glue storage ring cavity 31 through the one-way valve 37. When the movable ring 333 and the movable plate 32 move downward to squeeze the sealing material, the sealing material in the glue storage ring cavity 31 cannot flow upward through the one-way valve 37, ensuring that the sealing material can be squeezed downward smoothly.

[0044] Please see Figure 1 , Figure 6 and Figure 7 The telescopic mechanism 5 includes an outer sleeve 51 fixedly installed at the bottom of the top plate 21 and corresponding one-to-one with the glue injection hole 36. An inner sleeve 52 is slidably installed at the bottom of the outer sleeve 51. The inner sleeve 52 is located directly above the glue cylinder 4. A second lead screw 53 is threadedly connected to the top of the inner sleeve 52. The second lead screw 53 is rotatably connected to the outer sleeve 51. A drive assembly 54 for driving several second lead screws 53 to rotate is installed on the top plate 21.

[0045] Please see Figure 1 , Figure 6 and Figure 7 The drive assembly 54 includes a transmission gear ring 541 rotatably mounted on the top of the top plate 21. The top end of the lead screw 53 rotatably extends through the top of the top plate 21 and is fixedly connected to a transmission gear 542. Several transmission gears 542 mesh with the outer side of the transmission gear ring 541. A drive gear 543 located inside the transmission gear ring 541 is rotatably mounted on the top of the top plate 21. The drive gear 543 meshes with the inner side of the transmission gear ring 541. A rotating handle 544 is fixedly mounted on the top of the drive gear 543.

[0046] In practical use, rotating the handle 544 drives the drive gear 543 to rotate, which in turn drives the transmission gear ring 541 to rotate. The transmission gear ring 541 then drives the transmission gear 542 and the lead screw 53 to rotate. The lead screw 53 drives the inner sleeve 52 to move downward, causing the inner sleeve 52 to push the glue cylinder 4 downward. This forces the sealing material inside the glue cylinder 4 to be squeezed out from the bottom outlet, allowing the sealing material to enter the glue storage ring cavity 31 through the glue injection hole 36 and the one-way valve 37. This facilitates the replenishment of the sealing material and meets the needs of multi-point detection.

[0047] Please see Figure 1 and Figure 3 The testing mechanism 2 also includes a glass tube 22 fixedly installed on the top plate 21. The glass tube 22 has a scale. A valve 23 is fixedly installed at the bottom of the top plate 21. The top of the valve 23 is connected to the bottom of the glass tube 22. A connecting pipe 24 is fixedly connected between the bottom of the valve 23 and the top of the standard ring 1. The bottom of the connecting pipe 24 is connected to the bottom of the standard ring 1 through the inner diameter of the standard ring 1.

[0048] In practical use, after the sealing material is filled between the bottom of the standard ring 1 and the top of the bridge deck, add pure water to the glass tube 22, and then open the valve 23 to allow the pure water to flow through the valve 23 and the connecting pipe 24 to the bottom of the standard ring 1. When the water level drops by 100ml, immediately start the stopwatch and read the scale of the glass tube 22 every 60 seconds until the water level drops by 500ml.

[0049] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," "installed," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, an integral connection, or a sliding connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
