Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an array type chloride ion sensor pre-embedded device. Background Art

[0002] Sensors for non-destructive detection of chloride ion corrosion in concrete include electrical sensors, ultrasonic sensors, infrared temperature sensors, electrochemical sensors, and fiber optic sensors. Fiber optic sensors are commonly used. To ensure that the fiber optic sensor can monitor the degree of chloride ion corrosion in concrete, it is necessary to pre-embed the fiber optic sensor in the frame before the concrete is poured. However, in conventional existing technologies, the pre-embedding of chloride ion sensors is mostly done manually. This pre-embedding method is not only inefficient, but also generally involves a high height of the steel cage. Manual pre-embedding of chloride ion sensors poses a great threat to the personal safety of workers. Therefore, the existing technology urgently needs a technical solution to solve the above problems. Utility Model Content

[0003] The purpose of the utility model is to provide an array type chloride ion sensor pre-embedded device to solve the problems in the prior art.

[0004] In order to solve the above technical problems, the present invention specifically provides the following technical solutions:

[0005] An array-type chloride ion sensor pre-embedded device includes a steel cage, to which multiple steel rings are fixedly connected at equal intervals in the vertical direction. Two pre-embedded brackets are rotatably connected to the steel rings located on the top layer of the steel cage. Multiple sensor components are fixedly installed on the two pre-embedded brackets, and the bottoms of the two pre-embedded brackets are slidably connected to a stabilizing component.

[0006] Based on a preferred solution provided by an array-type chloride ion sensor embedded device, the sensor assembly includes a mounting base fixedly mounted on the embedded bracket, and a fiber optic sensor and a temperature compensation sensor are fixedly mounted on the side of the mounting base away from the embedded bracket.

[0007] Based on a preferred solution provided by an array-type chloride ion sensor embedded device, the stabilizing component includes two clamps that are slidably sleeved on the embedded bracket, and the two clamps are provided with mounting holes at one end away from the embedded bracket. The two clamps cooperate with each other to make the embedded bracket fit with the steel ring.

[0008] Based on a preferred solution provided by an array-type chloride ion sensor pre-embedded device, the top of the pre-embedded bracket is fixedly connected to an elbow, and the bottom of the elbow is fixedly connected to an extended elbow.

[0009] Based on a preferred solution provided by an array-type chloride ion sensor pre-embedded device, the extended elbow, the elbow and the pre-embedded bracket are all hollow, each of the sensor components is connected to a power cord group, and each of the power cord groups passes through the interior of the pre-embedded bracket, the elbow and the extended elbow in sequence to communicate with the outside world.

[0010] Based on a preferred solution provided by an array-type chloride ion sensor embedded device, a plurality of the sensor components are staggeredly distributed outside the two embedded brackets along the length direction of the steel cage.

[0011] Compared with the prior art, the present invention has the following beneficial effects: the pre-embedding method in the present invention not only effectively improves work efficiency, but also reduces the number of steps involving manual participation in the pre-embedding process, providing a certain degree of protection for the personal safety of workers. In addition, the spacing of the sensor components is controlled by the pre-embedded bracket, which effectively improves the coverage completeness of the entire pre-embedded device during actual detection.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

[0019] The following first describes the concepts involved in this application with reference to the accompanying drawings. It should be noted that the following description of each concept is intended only to make the content of this application easier to understand and does not limit the scope of protection of this application. At the same time, the embodiments and features in the embodiments of this application can be combined with each other unless there is a conflict. The following detailed description of this application will be made with reference to the accompanying drawings and in conjunction with the embodiments.

[0020] Example

[0021] like Figures 1 to 4 As shown, the utility model provides an array-type chloride ion sensor embedded device, including a steel cage 1, to which a plurality of steel rings 2 are fixedly connected at equal intervals along the vertical direction, and two embedded brackets 3 are rotatably connected to the steel ring 2 located on the top layer of the steel cage 1, and a plurality of sensor components 4 are fixedly installed on the two embedded brackets 3, and a stabilizing component 5 is slidably connected to the bottom of the two embedded brackets 3.

[0022] As a further explanation of this embodiment, in the prior art, in order to ensure that the optical fiber sensor 42 monitors the degree of chloride ion corrosion in the concrete, it is necessary to pre-embed the optical fiber sensor 42 in the frame before the concrete is poured. However, the chloride ion sensor in the conventional prior art is mostly pre-embedded by manual installation. This pre-embedding method is not only inefficient, but also the height of the steel cage 1 is generally high. The manual pre-embedding of the chloride ion sensor will pose a great hidden danger to the personal safety of the workers.

[0023] In this embodiment, by fixing a plurality of sensor components 4 on the embedded bracket 3, the sensor components 4 are array-planned in advance so that the sensor components 4 can monitor the chloride ion erosion at various points in the concrete, and then the two embedded brackets 3 with the sensor components 4 are placed from the top of the steel cage 1 until the top of the embedded bracket 3 is rotatably connected to the steel ring 2 at the top of the steel cage 1. After the embedded bracket 3 is rotated to a preset angle, the embedded bracket 3 and the steel cage 1 are fixedly connected by the stabilizing component 5, and the embedding operation of the chloride ion sensor component 4 is completed. This embedding method not only effectively improves work efficiency, but also has fewer steps of manual participation in the embedding process, which provides a certain guarantee for the personal safety of workers. In addition, the spacing of the sensor components 4 is controlled in advance by the embedded bracket 3, which effectively improves the coverage completeness of the entire embedded device during actual detection.

[0024] According to a preferred solution provided by the array-type chloride ion sensor embedded device, the sensor assembly 4 includes a mounting base 41 fixedly mounted on the embedded bracket 3, and a fiber optic sensor 42 and a temperature compensation sensor 43 are fixedly mounted on the side of the mounting base 41 away from the embedded bracket 3.

[0025] As a further illustration of this embodiment, the fiber optic sensor 42 in this embodiment is used to detect chloride ion concentration. It is primarily divided into fiber optic sensors 42 based on the ambient refractive index and fiber optic sensors 42 based on the fluorescence quenching principle. The fiber optic chloride ion sensor 42 based on the ambient refractive index is generally designed using a long-period fiber grating (LPFG). The sensing principle is as follows: when the refractive index of the external medium changes, the central wavelength of the LPFG shifts. Changes in chloride ion concentration cause changes in the refractive index of the solution. By observing and recording the change in the central wavelength of the LPFG, the chloride ion concentration can be detected. Because LPFG is extremely sensitive to temperature, LPFG-based chloride ion concentration sensors must be equipped with a temperature compensation sensor 43 in practical engineering applications. Fiber optic sensors 42 based on the fluorescence quenching principle primarily combine a fluorescent indicator specifically sensitive to chloride ions with an optical fiber through certain chemical or physical methods to create a fiber optic sensing probe. Fluorescence information generated by the sensitive membrane is obtained using a reflected or transmitted light path. A mathematical equation is then established based on the relationship between chloride ion concentration and relative fluorescence intensity to achieve quantitative detection of chloride ion concentration.

[0026] According to a preferred solution provided by the array-type chloride ion sensor embedded device, the stabilizing component 5 includes two clamps 51 that are slidably sleeved on the embedded bracket 3. The two clamps 51 are provided with mounting holes 52 at one end away from the embedded bracket 3. The two clamps 51 cooperate with each other to make the embedded bracket 3 fit with the steel ring 2.

[0027] As a further explanation of this embodiment, the stabilizing component 5 in this embodiment is to fit the embedded bracket 3 and the steel bar ring 2 together by clamping the steel bar ring 2 with two clamps 51, and bolts or screws for fixing the clamps 51 are installed in the mounting holes 52.

[0028] According to a preferred solution provided by the array-type chloride ion sensor pre-embedded device, the top of the pre-embedded bracket 3 is fixedly connected to an elbow 31 , and the bottom of the elbow 31 is fixedly connected to an extended elbow 32 .

[0029] As a further explanation of this embodiment, the elbow 31 in this embodiment is used to hook the entire embedded bracket 3 on the topmost steel bar ring 2 of the steel cage 1, so that the embedded bracket 3 is rotatably connected to the steel bar ring 2, which facilitates the stabilizing component 5 to fix the embedded bracket 3 and fix the embedded bracket 3 to the steel cage 1.

[0030] According to a preferred solution provided by the array-type chloride ion sensor pre-embedded device, the extended bend 32, the elbow 31 and the embedded bracket 3 are all hollow, each sensor component 4 is connected to a power cord group, and each power cord group passes through the interior of the embedded bracket 3, the elbow 31 and the extended bend 32 in sequence to communicate with the outside world.

[0031] As a further explanation of this embodiment, the sensor assembly 4 in this embodiment needs to perform real-time monitoring and data transmission through a power line and a data line. The data line and the power line are placed directly in the concrete. After the concrete is formed, the concrete may expand or contract to a certain extent due to the influence of temperature, which may cause certain damage to the line. Therefore, the line is protected by a reserved hollow pipe to extend the overall service life of the sensor assembly 4.

[0032] According to a preferred solution provided by the array-type chloride ion sensor embedded device, a plurality of sensor components 4 are staggeredly distributed outside the two embedded brackets 3 along the length direction of the steel cage 1 .

[0033] As a further explanation of this embodiment, the sensor components 4 on the two embedded brackets 3 in this embodiment are staggered and distributed in a certain regular pattern to avoid overlap in the detection range of the sensor components 4, thereby improving the detection range of the sensor components 4 for concrete and providing more complete monitoring data.
