Description

Technical Field

[0001] This invention relates to the field of reinforced concrete technology, specifically to a device for monitoring steel corrosion in reinforced concrete structures. Background Technology

[0002] Reinforced concrete, often simply referred to as reinforced concrete in engineering, is a composite material created by incorporating steel mesh, steel plates, or fibers into concrete to improve its mechanical properties. The ability of reinforced concrete to work together is determined by its inherent material properties. First, the steel bars and concrete have approximately the same coefficient of linear expansion, preventing excessive stress caused by environmental differences. Second, there is good bond between the steel bars and concrete. Sometimes, the surface of the steel bars is machined with spaced ribs to enhance the mechanical interlocking between the concrete and the steel bars. When this is still insufficient to transfer the tensile force between the steel bars and concrete, the ends of the steel bars are usually bent into 90-degree hooks. Furthermore, the alkaline environment provided by calcium hydroxide in the concrete forms a passivating protective film on the surface of the steel bars, making them less susceptible to corrosion compared to neutral and acidic environments.

[0003] Current steel corrosion monitoring devices for reinforced concrete structures require two people to hold the copper sulfate electrode and clamps respectively, which can easily lead to tangled wiring. Furthermore, if the copper sulfate electrode falls off, it can easily damage the main unit of the steel corrosion detector. Summary of the Invention

[0007] A lifting mechanism is used to fix and transport monitoring instruments. The lifting mechanism includes a steel corrosion detector. The steel corrosion detector has a first interface and a second interface inside. A first wiring is fixedly connected inside the first interface. A protective sleeve is sleeved on the outside of the first wiring. A flexible rod is fixedly connected inside the protective sleeve.

[0008] Preferably, the bottom of the base is fixedly connected to a caster wheel, the inside of the fixed cylinder is fixedly connected to a water tank, and the inside of the water tank is fixedly connected to a telescopic tube.

[0009] Preferably, a fan box is fixedly connected to the top of the lifting frame, a fan is fixedly connected inside the fan box, and a fixed pipe is fixedly connected inside the fan box.

[0010] Preferably, a second wiring is fixedly connected internally to the second interface, a handle is fixedly connected externally to the second wiring, a copper sulfate electrode is snapped onto the outside of the handle, and a clamp is fixedly connected externally to the first wiring.

[0012] Preferably, the skateboard has a groove inside, a third electric push rod is fixedly connected to the outside of the skateboard, a second receiving box is fixedly connected to the outside of the third electric push rod for holding the handle, and an arc-shaped plate is fixedly connected inside the second receiving box.

[0013] Preferably, a locking rod is fixedly connected to the outside of the second receiving box, a circular plate is fixedly connected to the outside of the arc-shaped plate, a nozzle is fixedly connected to the inside of the circular plate for wetting the sponge outside the copper sulfate electrode, and a suction tube is fixedly connected to the outside of the nozzle.

[0014] Preferably, the monitoring mechanism includes a semi-circular plate, a second electric telescopic column and a telescopic frame are fixedly connected to the top of the semi-circular plate, a motor box is fixedly connected to the top of the second electric telescopic column, a servo motor is fixedly connected inside the motor box, a rotating column is fixedly connected to the output end of the servo motor, and the semi-circular plate is fixedly connected to the outside of the first electric push rod.

[0015] Preferably, a fixing ring is fixedly connected to the outside of the rotating column, a fixing plate is fixedly connected to the outside of the fixing ring, and a fourth electric push rod is fixedly connected to the outside of the fixing plate.

[0016] Preferably, a clamping plate is fixedly connected to the outside of the fourth electric push rod, and an electric push plate is fixedly connected to the outside of the clamping plate to hold the handle. A rubber cylinder is fixedly connected to the top of the semi-circular plate to store and transport water, and a spray pipe is fixedly connected to the outside of the rubber cylinder.

[0017] This invention provides a device for monitoring steel corrosion in reinforced concrete structures. It has the following beneficial effects:

[0018] 1. The steel corrosion monitoring device in this reinforced concrete structure, through the installation of a control mechanism and a lifting mechanism, keeps the steel corrosion detector inside a fixed cylinder for protection. Furthermore, the two external wiring connections of the steel corrosion detector are fixed within the protective cylinder to prevent tangling and knotting. This achieves the purpose of facilitating the placement and protection of the steel corrosion detector.

[0019] 2. The steel corrosion monitoring device in this reinforced concrete structure, through the installation of a lifting mechanism, addresses the issue that conventional monitoring work requires two people, each holding a copper sulfate electrode and clamps, which can easily lead to wire tangling. Furthermore, if the copper sulfate electrode falls, it can easily damage the main unit of the steel corrosion detector. Therefore, the above problems are solved by fixing the lower middle part of the first and second wires in the device. This achieves the purpose of facilitating the control of the steel corrosion detector's position and protecting the two wires from tangling.

[0020] 3. The steel corrosion monitoring device in this reinforced concrete structure features a processing mechanism that supports the bottom of the copper sulfate electrode and wets the sponge surrounding the electrode with water, allowing for direct use. This avoids damage to the device caused by water falling into the steel corrosion detector during manual disassembly and sponge installation. This design facilitates easy control of the handle height and allows for efficient corrosion monitoring.

[0021] 4. The steel corrosion monitoring device in this reinforced concrete structure, through the installation of a monitoring mechanism, can be adjusted according to two different monitoring conditions. When monitoring the vertical reinforced concrete is required, water is sprayed onto the test surface, and then the handle position is controlled to perform monitoring. When monitoring the horizontal reinforced concrete is required, the pipeline can be manually changed, and the operation can be repeated. This achieves the purpose of facilitating corrosion monitoring of reinforced concrete in both vertical and horizontal directions. Attached Figure Description

Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0032] like Figures 1-8 As shown, the present invention provides a technical solution, specifically including:

[0033] A base 1 is fixedly connected to a fixed cylinder 2 at its top. A control mechanism 4 is fixedly connected inside the fixed cylinder 2. A first electric push rod 7 is fixedly connected to the outside of the fixed cylinder 2. A monitoring mechanism 8 is fixedly connected to the outside of the first electric push rod 7.

[0034] The control mechanism 4 is used to determine the height of the equipment inside the fixed cylinder 2. The control mechanism 4 includes a first slide rail 401 and a second slide rail 406. A first electric telescopic column 402 is fixedly connected inside the first slide rail 401. A lifting frame 403 is fixedly connected to the top of the first electric telescopic column 402. A connecting column 404 is fixedly connected to the top of the lifting frame 403. A sliding plate 405 is fixedly connected to the outside of the connecting column 404. Both the first slide rail 401 and the second slide rail 406 are located inside the fixed cylinder 2. A processing mechanism 6 is fixedly connected to the outside of the control mechanism 4.

[0035] The lifting mechanism 5 is used to fix and transport the monitoring instrument. The lifting mechanism 5 includes a steel corrosion detector 501. The lifting frame 403 is equipped with a power supply, which is connected to the steel corrosion detector 501. The steel corrosion detector 501 has a first interface 505 and a second interface 506 inside. A first wiring 510 is fixedly connected inside the first interface 505. A protective sleeve 504 is sleeved on the outside of the first wiring 510. A flexible rod 509 is fixedly connected inside the protective sleeve 504. The steel corrosion detector 501 is snapped into the inside of the lifting frame 403.

[0036] A caster wheel is fixedly connected to the bottom of the base 1. A water tank 3 is fixedly connected inside the fixed cylinder 2. A water pump is fixedly connected inside the water tank 3. A telescopic pipe 9 is fixedly connected inside the water tank 3. When using the equipment, the first electric telescopic column 402 in the control mechanism 4 is activated. The first electric telescopic column 402 drives the lifting frame 403 to move upward inside the first slide rail 401, thereby driving the steel corrosion detector 501 inside the lifting frame 403 to move upward. During the upward movement of the lifting frame 403, the connecting column 404 and the sliding plate 405 follow the lifting frame 403 and move upward inside the second slide rail 406. At this time, the lifting mechanism 5 and the processing mechanism 6 follow the lifting frame 403 upward. During the ascent, the lifting mechanism 5 protects the first wiring 510, and the processing mechanism 6 protects the steel corrosion detector 501. The monitoring mechanism 8 is activated to perform monitoring work.

[0037] The top of the lifting frame 403 is fixedly connected to the fan box 502, the inside of the fan box 502 is fixedly connected to the fan, and the inside of the fan box 502 is fixedly connected to the fixed pipe 503.

[0038] The second interface 506 has a second wire 512 fixedly connected internally, and a handle 507 fixedly connected externally to the second wire 512. A copper sulfate electrode 508 is externally engaged with the handle 507. A clamp 511 is externally fixedly connected to the first wire 510. Both the first wire 510 and the second wire 512 are located inside the protective cylinder 504, and a flexible rod 509 is provided inside the protective cylinder 504 to prevent damage to the first wire 510 and the second wire 512. Before using the clamp 511, the clamp 511 is located inside the fixed tube 503. When the fan in the fan box 502 is turned on, the air in the fan moves upward through the fixed tube 503, causing the dust outside the clamp 511 to move outward, preventing poor contact during subsequent use.

[0039] The processing mechanism 6 includes a second electric push rod 601, a first receiving box 602 is fixedly connected to the outside of the second electric push rod 601, a locking hole is opened inside the first receiving box 602, a third electric telescopic column 603 is fixedly connected to the top of the first receiving box 602, a suction cup is fixedly connected to the top of the third electric telescopic column 603, and the second electric push rod 601 is fixedly connected to the outside of the slide plate 405.

[0040] The skateboard 405 has a groove 604 inside, and a third electric push rod 605 is fixedly connected to the outside of the skateboard 405. A second receiving box 606 is fixedly connected to the outside of the third electric push rod 605, and an arc plate 608 is fixedly connected inside the second receiving box 606.

[0041] The second receiving box 606 is externally fixedly connected to a locking rod 607, which engages with a locking hole. When the second electric push rod 601 and the third electric push rod 605 are activated, they respectively drive the first receiving box 602 and the second receiving box 606 towards the center until the locking rod 607 engages with the locking hole. At this point, a small gap exists between the first receiving box 602 and the second receiving box 606, sufficient to accommodate the second wiring 512 and prevent it from being impacted. The arc-shaped plate 608 is externally fitted with a water-absorbing shell, and a circular plate 609 is fixedly connected to the outside of the arc-shaped plate 608. A nozzle 610 is fixedly connected inside the circular plate 609, and a suction tube 611 is fixedly connected to the outside of the nozzle 610. The suction tube 611 is fixedly connected inside the water tank 3. The handle 507 is positioned on the suction cup above the third electric telescopic column 603, and the two copper sulfate electrodes 508 at the bottom of the handle 507 are located inside the two arc-shaped plates 608. When the water pump in the water tank 3 is turned on, water is drawn from the tank into the suction pipe 611. When the nozzle 610 is turned on, water is sprayed onto the sponge outside the copper sulfate electrodes 508, humidifying the sponge. The arc-shaped plates 608 are fitted with absorbent shells to absorb excess moisture. When the third electric telescopic column 603 is turned on, it causes the handle 507 to move upwards.

[0042] The monitoring mechanism 8 includes a semicircular plate 801. A second electric telescopic column 802 and a telescopic frame 812 are fixedly connected to the top of the semicircular plate 801. A motor box 803 is fixedly connected to the top of the second electric telescopic column 802. A servo motor is fixedly connected inside the motor box 803. A rotating column 804 is fixedly connected to the output end of the servo motor. The semicircular plate 801 is fixedly connected to the outside of the first electric push rod 7.

[0043] A fixing ring 805 is fixedly connected to the outside of the rotating column 804. A pressing plate is fixedly connected to the bottom of the fixing ring 805. A fixing plate 806 is fixedly connected to the outside of the fixing ring 805. A fourth electric push rod 807 is fixedly connected to the outside of the fixing plate 806.

[0044] The fourth electric push rod 807 is externally fixedly connected to a clamping plate 808, and the clamping plate 808 is externally fixedly connected to an electric push plate 809. Two electric push plates 809 are provided. A rubber cylinder 810 is fixedly connected to the top of the semi-circular plate 801. The rubber cylinder 810 is fixedly connected to the telescopic pipe 9, and a spray pipe 811 is fixedly connected to the outside of the rubber cylinder 810. If monitoring is required for vertical reinforced concrete, the servo motor is activated. The servo motor drives the fixing ring 805 and the extrusion plate to rotate. The extrusion plate begins to extrude water from the bottom rubber cylinder 810, and the water in the rubber cylinder 810 is sprayed outwards through the spray pipe 811 onto the reinforced concrete for surface pretreatment. If monitoring is required for horizontal reinforced concrete, a curved pipe is manually fitted over the spray pipe 811, and the above process is repeated for water spraying.

[0045] Activate the fourth electric push rod 807, which drives the clamping plate 808 to move outward. Activate the two electric push plates 809, which clamp the handle 507. Depending on the test position, the servo motor in the motor box 803 can be activated. The servo motor drives the rotating column 804 to rotate, which in turn drives the fixing ring 805, fixing plate 806, fourth electric push rod 807, and clamping plate 808 to move. This, in turn, moves the handle 507 to the test position. At this time, the sponge outside the copper sulfate electrode 508 contacts the surface of the reinforced concrete. Manually clamp the clamp 511 on the exposed steel bar and activate the steel bar corrosion detector 501 to perform monitoring.

[0046] Working principle: When using the equipment, the first electric telescopic column 402 in the control mechanism 4 is activated. The first electric telescopic column 402 drives the lifting frame 403 to move upward inside the first slide rail 401, which in turn drives the steel corrosion detector 501 inside the lifting frame 403 to move upward.

[0047] During the upward movement of the lifting frame 403, the connecting column 404 and the sliding plate 405 follow the lifting frame 403 upward movement inside the second slide rail 406. At this time, the lifting mechanism 5 and the processing mechanism 6 also follow the lifting frame 403 upward movement. During the ascent, the lifting mechanism 5 protects the first wiring 510. Both the first wiring 510 and the second wiring 512 are inside the protective cylinder 504, and a flexible rod 509 is installed inside the protective cylinder 504 to prevent damage to the first wiring 510 and the second wiring 512. Before using the clamp 511, the clamp 511 is inside the fixed pipe 503. The fan in the fan box 502 is turned on, and the air from the fan moves upward through the fixed pipe 503, causing dust outside the clamp 511 to move outward, preventing poor contact during subsequent use.

[0048] The processing mechanism 6 protects the steel corrosion detector 501. The second electric push rod 601 and the third electric push rod 605 are activated, causing the first receiving box 602 and the second receiving box 606 to move towards the center until the locking rod 607 engages with the locking hole. At this point, a small gap exists between the first receiving box 602 and the second receiving box 606, sufficient to accommodate the second wiring 512 and prevent it from being impacted. The handle 507 is positioned on the suction cup above the third electric telescopic column 603, and the two copper sulfate electrodes 508 at the bottom of the handle 507 are located inside the two arc-shaped plates 608. The water pump in the water tank 3 is activated, drawing water from the tank into the suction pipe 611. The nozzle 610 is activated, spraying water onto the sponge outside the copper sulfate electrodes 508, humidifying the sponge. The arc-shaped plates 608 are fitted with absorbent shells to absorb excess moisture. Activate the third electric telescopic column 603, which in turn drives the handle 507 to move upward.

[0049] Activate monitoring mechanism 8 to begin monitoring. If monitoring is being performed on vertical reinforced concrete, activate the servo motor. The servo motor drives the fixed ring 805 and the extrusion plate to rotate. The extrusion plate then extrudes the rubber cylinder 810 at the bottom. Water from the rubber cylinder 810 is sprayed outwards through the spray pipe 811 onto the reinforced concrete for surface pretreatment. If monitoring is being performed on horizontal reinforced concrete, manually attach a curved pipe to the outside of the spray pipe 811, and then repeat the above steps for water spraying.

[0050] Activate the fourth electric push rod 807, which drives the clamping plate 808 to move outward. Activate the two electric push plates 809, which clamp the handle 507. Depending on the test position, the servo motor in the motor box 803 can be activated. The servo motor drives the rotating column 804 to rotate, which in turn drives the fixing ring 805, fixing plate 806, fourth electric push rod 807, and clamping plate 808 to move. This, in turn, moves the handle 507 to the test position. At this time, the sponge outside the copper sulfate electrode 508 contacts the surface of the reinforced concrete. Manually clamp the clamp 511 on the exposed steel bar and activate the steel bar corrosion detector 501 to perform monitoring.
