Road bridge water seepage detection device

Abstract

This utility model discloses a road and bridge seepage detection device, belonging to the technical field of road inspection equipment. Its key technical features include a detection cylinder with visual detection mechanisms at both the bottom and outer side. By setting these visual detection mechanisms, during testing, the bottom-mounted adhesive hopper connected to the drain valve at the bottom of the detection cylinder is placed on the bridge surface to be tested. Squeezing the adhesive hopper ensures its sides are in close contact with the ground, achieving initial sealing. The bottom-mounted suction cup deforms under pressure and adheres to the ground. The reinforcing ring enhances its structural stability, and the counterweight ring at the top of the supporting edge further stabilizes the device through gravity pressure, reducing the possibility of deviation of the detection area due to external forces and effectively lowering the probability of gap formation. After opening the drain valve, the water in the detection cylinder is discharged through the adhesive hopper to the bridge surface test area. At this time, the transparent acrylic viewing cover on the outside of the adhesive hopper allows for direct observation of the seepage point location, water flow status, and seepage process.

Description

Technical Field

[0001] This utility model relates to the field of road inspection equipment technology, and in particular to a road and bridge seepage detection device. Background Technology

[0002] A bridge is generally a structure built over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, the term "bridge" has also been extended to refer to a building that crosses mountain streams, adverse geological conditions, or meets other transportation needs to make travel more convenient.

[0003] Currently, in the use of bridge seepage detection devices, some bridge seepage detection requires water injection on local surfaces. However, the water source for local injection lacks containment, causing water to flow in all directions and affecting the detection results.

[0004] An existing patent (publication number: CN221528347U) discloses a road and bridge seepage detection device. This utility model has a novel design and simple structure.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, in practical applications, existing road and bridge seepage detection devices still have significant shortcomings. The detection area is mostly a closed structure, lacking transparent observation components, making it impossible to directly observe the location of seepage points, water flow status, and seepage process. It is also difficult to confirm the fit between the device and the bridge surface. If gaps exist, it can easily lead to distorted detection data and misjudgments. At the same time, the sealing fit between the device and the detection surface is poor, easily resulting in gaps, and there is a lack of effective fixing structure, making it easy for the detection area to deviate from the preset position.

[0006] Therefore, a road and bridge seepage detection device is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a road and bridge seepage detection device that can solve the obvious shortcomings of existing road and bridge seepage detection devices. The detection area is mostly a closed structure, lacking transparent observation components, making it impossible to directly observe the location of seepage points, water flow status, and seepage process. It is also difficult to confirm the fit between the device and the bridge surface. If there are gaps, it can easily lead to distorted detection data and misjudgments. At the same time, the sealing fit between the device and the detection surface is not good, which can easily produce gaps. Furthermore, the lack of an effective fixing structure makes it easy for the detection area to deviate from the preset position.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a road and bridge seepage detection device, comprising a detection cylinder, wherein a visual detection mechanism is provided at the bottom and on the outer side of the detection cylinder;

[0009] The visual inspection mechanism includes a drain valve connected to the bottom of the inspection cylinder, a bottom adhesive hopper connected to the bottom of the drain valve, a viewing cover fixedly connected to the outside of the drain valve, the viewing cover being located outside the bottom adhesive hopper, the viewing cover being made of transparent acrylic material, a reinforcing ring fixedly connected to the bottom of the viewing cover, a bottom adhesive suction cup fixedly connected to the bottom of the reinforcing ring, a supporting edge ring fixedly connected to the outside of the bottom adhesive suction cup, and counterweight pressure rings provided on the front and rear sides of the top of the supporting edge ring, an internal measuring structure provided inside the inspection cylinder, and a top-blocking measuring structure provided on the top of the inspection cylinder.

[0010] Preferably, the internal measuring structure includes grooves on both sides inside the detection cylinder, and a transparent measuring plate is fixedly connected to the outer side inside the groove.

[0011] Preferably, a buoyancy block is provided inside the detection cylinder, and the buoyancy block is located at the bottom of the top-blocking measurement structure.

[0012] Preferably, sliders are fixedly connected to both sides of the buoyancy block, and the sliders are slidably connected inside the groove.

[0013] Preferably, the plug measuring structure includes a plug that is threaded to the top of the detection cylinder, and a sliding sleeve is fixedly connected inside the plug.

[0014] Preferably, a lifting measuring rod is slidably connected inside the sliding sleeve. The lifting measuring rod is made of lightweight material, and the bottom of the lifting measuring rod contacts the top of the buoyancy block.

[0015] Preferably, a limiting block is fixedly connected to the top of the lifting measuring rod, and the limiting block is located at the top of the plug.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This application establishes a visual inspection mechanism. During inspection, the bottom-mounted adhesive hopper connected to the drain valve at the bottom of the inspection cylinder is placed on the bridge surface to be inspected. The adhesive hopper is squeezed to make its side tightly contact the ground, achieving initial sealing. The bottom-mounted suction cup is deformed by the squeezing and adsorbs onto the ground. The reinforcing ring enhances its structural stability. The counterweight pressure ring at the top of the support ring further stabilizes the device through gravity pressure, reducing the possibility of deviation of the inspection area due to external forces and effectively reducing the probability of gap formation. After the drain valve is opened, the water in the inspection cylinder is discharged to the bridge surface test area through the adhesive hopper. At this time, the transparent acrylic viewing cover on the outside of the adhesive hopper can directly observe the location of the seepage point, the water flow status, and the seepage process. It can also confirm the adhesion between the adhesive hopper and the bridge surface in real time, avoiding data distortion and misjudgment due to insufficient sealing. This solves the problems of poor visibility and insufficient sealing caused by the closed structure of the existing device.

[0018] 2. This application, by setting up an internal measurement structure and a top-blocking measurement structure, allows the internal measurement structure inside the detection cylinder to accurately sense changes in liquid level when water in the detection cylinder is discharged to the bridge deck test area through the bottom adhesive hopper. This facilitates observation of the water level. Simultaneously, the top-blocking measurement structure at the top of the detection cylinder works in sync with the internal measurement structure to simultaneously measure the water level inside the detection cylinder. Together, they reduce the impact of water flow disturbance on liquid level feedback, improve the real-time performance and accuracy of the measurement, and solve the problems of insufficient stability and large measurement errors in the buoyancy sensing structure of existing devices.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 The present invention provides the following technical solution:

[0027] A road and bridge seepage detection device includes a detection cylinder 1, and a visual detection mechanism 2 is provided at the bottom and outside of the detection cylinder 1.

[0028] The visual inspection mechanism 2 includes a drain valve 21 connected to the bottom of the inspection cylinder 1. The bottom of the drain valve 21 is connected to a bottom adhesive hopper 22. A viewing cover 23 is fixedly connected to the outside of the drain valve 21. The viewing cover 23 is located outside the bottom adhesive hopper 22. The viewing cover 23 is made of transparent acrylic material. A reinforcing ring 24 is fixedly connected to the bottom of the viewing cover 23. A bottom suction cup 25 is fixedly connected to the bottom of the reinforcing ring 24. A support edge ring 26 is fixedly connected to the outside of the bottom suction cup 25. A counterweight pressure ring 27 is provided on the front and rear sides of the top of the support edge ring 26. An internal measuring structure 28 is provided inside the inspection cylinder 1. A top-blocking measuring structure 29 is provided on the top of the inspection cylinder 1.

[0029] In this embodiment: by setting up a detection cylinder 1 and a visual detection mechanism 2, during detection, the bottom adhesive hopper 22 is first placed on the bridge surface to be tested and squeezed to form a preliminary seal by making it in close contact with the ground. The bottom suction cup 25 is deformed by the squeeze and adsorbed onto the ground. The reinforcing ring 24 enhances the stability of the suction cup. The counterweight pressure ring 27 on the supporting edge ring 26 further stabilizes the device by gravity, reducing displacement and gaps. Then, the drain valve 21 is opened, and the water in the detection cylinder 1 is discharged to the bridge surface test area through the bottom adhesive hopper 22. At this time, the transparent acrylic viewing cover 23 on the outside of the bottom adhesive hopper 22 can observe the location of the seepage point, the water flow status, and the adhesion of the bottom adhesive hopper 22 in real time to ensure reliable sealing. At the same time, the internal measuring structure 28 inside the detection cylinder 1 accurately senses the liquid level change as the water level drops, and the top sealing measuring structure 29 works in sync to measure. The two work together to reduce the impact of water flow disturbance. By combining transparent observation and dual measurement, the visibility and sealing of the detection are improved, while the accurate monitoring of the seepage volume is achieved.

[0030] Specifically, such as Figure 4 As shown, the internal measuring structure 28 includes grooves 281 on both sides inside the detection cylinder 1, and a transparent measuring plate 282 is fixedly connected to the outer side inside the grooves 281.

[0031] Specifically, such as Figure 4 As shown, a buoyancy block 283 is installed inside the detection cylinder 1, and the buoyancy block 283 is located at the bottom of the top measuring structure 29.

[0032] Specifically, such as Figure 4 As shown, sliders 284 are fixedly connected to both sides of the buoyancy block 283, and the sliders 284 are slidably connected inside the groove 281.

[0033] In this embodiment: by setting an internal measuring structure 28, the sliding grooves 281 on both sides of the inside of the detection cylinder 1 provide sliding guidance for the sliders 284. When the inside of the detection cylinder 1 is full of water, the buoyancy block 283 is on the water surface and located on the top side inside the detection cylinder 1. When water seepage causes the water level inside the detection cylinder 1 to drop, the buoyancy block 283 drops with the liquid level, and the sliders 284 on both sides slide synchronously along the sliding grooves 281. With the help of the transparent measuring plate 282 on the outside of the sliding grooves 281, the liquid level scale corresponding to the position of the sliders 284 can be read intuitively, accurately reflecting the change in the amount of water seepage, and improving the stability and visibility of the measurement.

[0034] Specifically, such as Figure 3 As shown, the plug measuring structure 29 includes a plug 291 threadedly connected to the top of the detection cylinder 1, and a sliding sleeve 292 is fixedly connected inside the plug 291.

[0035] Specifically, such as Figure 3 As shown, a lifting measuring rod 293 is slidably connected inside the sliding sleeve 292. The lifting measuring rod 293 is made of lightweight material, and the bottom of the lifting measuring rod 293 contacts the top of the buoyancy block 283.

[0036] In this embodiment: by setting a top-plugging measuring structure 29, the plug 291 at the top of the detection cylinder 1 is threaded and easy to open and close, so as to refill water into the detection cylinder 1. The internal sliding sleeve 292 provides vertical guidance for the lifting measuring rod 293. When the buoyancy block 283 rises and falls with the liquid level, the lightweight lifting measuring rod 293 contacts the top of the buoyancy block 283 and moves synchronously, converting the liquid level change into the rise and fall of the lifting measuring rod 293, realizing a secondary accurate measurement of the liquid level, which complements the internal measuring structure 28 and reduces the error of a single measurement.

[0037] Specifically, such as Figure 3 As shown, a limiting block 3 is fixedly connected to the top of the lifting measuring rod 293, and the limiting block 3 is located at the top of the plug 291.

[0038] In this embodiment: by setting a limiting block 3, when the lifting measuring rod 293 descends to its maximum stroke with the buoyancy block 283, the limiting block 3 contacts the top of the plug 291 to prevent it from coming out of the sliding sleeve 292, ensuring that the lifting measuring rod 293 and the buoyancy block 283 remain in contact during the measurement process, thus ensuring the continuity and reliability of the measurement.

[0039] Working Principle: In the use of the road and bridge seepage detection device, firstly, the plug 291 is unscrewed from the top of the detection cylinder 1. After filling the detection cylinder 1 with water, the plug 291 is then reset via the threaded connection. At this time, the bottom of the lifting measuring rod 293 contacts the top of the buoyancy block 283. During testing, the bottom adhesive hopper 22 is placed on the bridge surface to be tested, and pressure is applied to ensure its sides are in close contact with the ground, forming a preliminary seal. The bottom suction cup 25 deforms under pressure and adheres to the ground. The reinforcing ring 24 enhances the stability of the suction cup, and the counterweight pressure ring 27 on the supporting edge ring 26 further stabilizes the device through gravity, reducing offset and gaps. Then, the drain valve 21 is opened, and the water in the detection cylinder 1 is discharged through the bottom adhesive hopper 22 to the bridge surface testing area. At this time, the operator can observe the seepage point location, water flow status, and the adhesion of the bottom adhesive hopper 22 in real time through the transparent acrylic viewing cover 23 to ensure... The system is reliably sealed. As the water level in the detection cylinder 1 decreases, the buoyancy block 283 descends synchronously with the liquid level. The sliders 284 on both sides slide along the slide groove 281. With the help of the transparent measuring plate 282 on the outside of the slide groove 281, the liquid level scale corresponding to the slider 284 can be read directly. At the same time, the lifting measuring rod 293, which is in contact with the buoyancy block 283, descends synchronously under the guidance of the sliding sleeve 292, converting the liquid level change into the lifting motion of the lifting measuring rod 293, thus realizing secondary measurement. The limiting block 3 prevents the lifting measuring rod 293 from falling out of the sliding sleeve 292. Through the combined operation of perspective observation, internal measurement, and top measurement, the visibility and sealing of the detection process can be ensured, and the changes in water leakage can be accurately monitored, improving the detection accuracy and reliability. After the detection is completed, the drain valve 21 is closed, and the plug 291 is unscrewed to replenish water into the detection cylinder 1 for the next detection.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
