Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of steel bar corrosion monitoring instruments, in particular to a steel bar concrete structure corrosion monitoring instrument. Background Art
[0002] Regular inspections of concrete structures such as buildings, bridges, and tunnels that have been in operation for many years using a steel corrosion monitor can assess the safety and durability of the structure. Long-term monitoring can reveal the development trends of steel corrosion, providing a scientific basis for structural repair, reinforcement, and renovation. For example, if monitoring reveals severe steel corrosion on a bridge, timely reinforcement may be necessary to ensure its safe operation.
[0003] Conventional steel corrosion monitors require two hands to operate, forcing them to be placed on the ground or on a platform, rather than in the optimal viewing position. This makes observation difficult. Furthermore, when placed on the ground, the viewing angle cannot be adjusted, potentially causing reflections when observing the monitor, which can affect judgment. Therefore, we propose a reinforced concrete structure corrosion monitor. Utility Model Content
[0004] The purpose of the utility model is to provide a reinforced concrete structure corrosion monitoring device to solve the problems raised in the above background technology.
[0005] In view of this, the utility model provides a reinforced concrete structure corrosion monitoring device, comprising:
[0006] A base, two mounting brackets are fixedly installed on the top of the base, and the rust monitor body is rotatably installed between the two mounting brackets. A sliding groove is provided in the base, and a rectangular groove is provided in the base and at the bottom of the sliding groove. Sliding blocks are symmetrically slidably installed in the sliding groove, and a rotating plate is rotatably installed at the bottom of the sliding block and located in the rectangular groove. A rubber pad and two magnets 1 are fixedly installed on the top of the rotating plate, a magnet 2 is symmetrically fixedly installed on the top of the rectangular groove, and a magnet 3 is fixedly installed on the bottom of the base and on both sides of the rectangular groove;
[0007] a driving assembly, the driving assembly being located in the sliding slot and being used to drive the two sliding blocks toward or away from each other;
[0008] The limiting component is located on the corrosion monitor body and is used to limit the corrosion monitor body.
[0009] When the two rotating plates are rotated downward, the two magnets 1 and 2 on the rotating plates are demagnetized, until the rotating plates are rotated downward to 90 degrees, and then the personnel can place the base on the shelf or railing, and then the driving assembly is used to drive the two sliding blocks closer to each other, and the two sliding blocks closer to each other will drive the two rotating plates closer to each other until the two rotating plates are clamped on the shelf or railing. At this time, the rubber pads on the rotating plates will be deformed, and under the action of the friction force of the rubber pads, the base can be firmly fixed to the shelf or railing, ensuring that the rust monitor body can be fixed in a suitable position, so that the personnel can observe the rust monitor body conveniently when performing two-handed operation;
[0010] By setting the limit component, when there is no iron material, shelf or railing at the detection location, the personnel can place the entire device on the ground, and then release the limit of the rust monitor body through the limit component. Then, the personnel can rotate the rust monitor body to adjust the observation angle of the rust monitor body. When the rust monitor body is adjusted to a suitable observation angle, the limit component can limit the rust monitor body to ensure that it is convenient for personnel to adjust the observation angle of the rust monitor body, and to ensure that there is no reflection when the rust monitor body is placed on the ground.
[0011] In the above technical solution, further, the driving component includes:
[0012] A bidirectional threaded rod is rotatably installed in the sliding groove, one end of the bidirectional threaded rod passes through two sliding blocks and one side of the sliding groove and extends to the outside, and a knob is fixedly installed on one end of the bidirectional threaded rod and located on one side of the base.
[0013] In this technical solution, by turning the knob, the rotation of the knob will drive the bidirectional threaded rod to rotate. Under the action of the thread, the rotation of the bidirectional threaded rod will drive the two sliding blocks closer to each other. The approach of the two sliding blocks to each other will drive the two rotating plates closer to each other until the two rotating plates are clamped on the shelf or railing. At this time, the rubber pads on the rotating plates will be deformed. Under the action of the friction force of the rubber pads, the base can be firmly fixed on the shelf or railing, ensuring that it is easy for personnel to fix the rust monitor body in a suitable position, so that personnel can easily observe the rust monitor body when operating with both hands.
[0014] In the above technical solution, further, the bidirectional threaded rod is threadedly connected to the sliding block, the bidirectional threaded rod is provided with two sections of threads with opposite rotation directions, and one end of the bidirectional threaded rod is rotatably connected to the base.
[0015] In this technical solution, it is ensured that the rotation of the bidirectional threaded rod can drive the two sliding blocks to move closer to or away from each other, and that one end of the bidirectional threaded rod can rotate normally in the base.
[0016] In the above technical solution, further, the limiting component includes:
[0017] A rectangular block is fixedly mounted on one side of the corrosion monitor body and is located on the top of the base. A slide groove is provided in the rectangular block. A plurality of limit holes are provided on the peripheral side of one of the mounting frames. A limit block is slidably installed in the slide groove. One end of the limit block passes through one side of the slide groove and extends into one of the limit holes. A spring fixed to the inner wall of the slide groove is fixedly mounted on the other end of the limit block. One side of the limit block passes through the slide groove and extends to the outside.
[0018] In this technical solution, when there is no iron material, shelf or railing at the detection location, the personnel can place the entire device on the ground, and then press the limit block to make the limit block move in the slide groove and squeeze the spring to contract until one end of the limit block moves out of one of the limit holes. At this time, the limit block can release the limit on the rust monitor body. Then, the personnel can rotate the rust monitor body to adjust the observation angle of the rust monitor body. When the rust monitor body is adjusted to a suitable observation angle, release the limit block. Under the action of the spring rebound force, the spring will squeeze the limit block to move until one end of the limit block is inserted into the corresponding limit hole. At this time, the limit block can limit the rust monitor body, ensuring that it is convenient for personnel to adjust the observation angle of the rust monitor body, and ensuring that there is no reflection when the rust monitor body is placed on the ground.
[0019] In the above technical solution, further, one end of the limiting block is plugged into the limiting hole, and a plurality of the limiting holes are distributed in a circular shape with equal intervals.
[0020] In this technical solution, it is ensured that one end of the limiting block can be inserted into the limiting hole, thereby ensuring the structural stability of the plurality of limiting holes.
[0021] In the above technical solution, further, the rotating plate is movably connected to the rectangular slot, and the first magnet is magnetically connected to the second magnet.
[0022] In this technical solution, it is ensured that the rotating plate can slide and rotate in the rectangular groove, and that the first magnet can be attracted to the second magnet.
[0023] In the above technical solution, further, the cross section of the sliding groove is a T-shaped structure.

[0026] 1. The reinforced concrete structure rust monitor, through the two magnets three provided, personnel can first adsorb the rust monitor body on the adjacent iron material through the two magnets three on the base. When there is no iron material in the detection area, the personnel can fix the rust monitor body on the adjacent shelf or railing. First, rotate the two rotating plates downward respectively, so that the two magnets one on the rotating plate and the two magnets two are demagnetized until the rotating plate rotates downward to 90°, and then the personnel can place the base on the shelf or railing. Then, through the provided driving component, the driving component will drive the two sliding blocks closer to each other, and the two sliding blocks approaching each other will drive the two rotating plates closer to each other until the two rotating plates are clamped on the shelf or railing. At this time, the rubber pad on the rotating plate will be deformed. Under the action of the friction force of the rubber pad, the base can be firmly fixed on the shelf or railing, ensuring that it is convenient for personnel to fix the rust monitor body in a suitable position, so that personnel can easily observe the rust monitor body when performing two-handed operation.
[0027] 2. The reinforced concrete structure rust monitor has a limit assembly. When there is no iron material, rack or railing at the detection location, the personnel can place the entire device on the ground, and then release the limit of the rust monitor body through the limit assembly. Then, the personnel can rotate the rust monitor body to adjust the observation angle of the rust monitor body. When the rust monitor body is adjusted to a suitable observation angle, the limit assembly can limit the rust monitor body to ensure that it is convenient for personnel to adjust the observation angle of the rust monitor body and ensure that there will be no reflection when the rust monitor body is placed on the ground.
