Description

Technical Field

[0001] This utility model relates to the field of road engineering technology, and in particular to an imaging device for evaluating defects in recycled aggregates used in raw concrete. Background Technology

[0002] With the continuous development of urbanization, a large number of buildings that have reached their service life and no longer meet current needs are being demolished or rebuilt, inevitably generating a large amount of construction waste. Waste concrete in construction solid waste can be used as raw material for engineering construction after crushing, screening and other treatments. However, since recycled aggregate itself contains a large amount of residual mortar and porous structure, it has obvious defects compared with natural aggregate. Arbitrary application in foundation engineering will cause considerable safety hazards. The importance of identifying the defects of recycled aggregate and judging whether it can be put into use is self-evident.

[0003] The combination of vegetated concrete and recycled aggregate is a highly promising green building material technology. It transforms waste concrete and other construction waste into recycled aggregate, which is then applied to vegetated concrete with high porosity and the ability to support vegetation growth. This combination achieves dual environmental benefits: it reduces construction waste landfill and natural sand and gravel mining, representing an important direction for the sustainable development of building materials. It has significant ecological, economic, and social benefits and a promising future.

[0004] However, due to the different sources of virgin concrete in different regions, the performance of recycled aggregates is highly variable. Therefore, it is unreasonable to judge whether recycled aggregates can be used solely based on performance index values. Currently, there is a lack of simple, convenient, and quantitative equipment to test and evaluate the defects of recycled aggregates.

[0005] In some existing technologies, the imaging devices for evaluating defects in recycled aggregates require taking pictures before the samples are evaluated for quality. Most of these devices require manual placement of the samples one at a time during the shooting process, which is slow and inefficient. Utility Model Content

[0006] The main purpose of this invention is to provide an imaging device for evaluating defects in recycled aggregates for planted concrete. This device can effectively solve the problems in some existing technologies where the imaging device for evaluating defects in recycled aggregates requires taking pictures before the sample is evaluated for quality. Most of these devices require manual placement of the sample at a time, resulting in slow shooting speed and low work efficiency.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] An imaging device for evaluating defects in recycled aggregates for plant-based concrete includes a camera mechanism, an adjustment mechanism fixedly connected to the bottom of the camera mechanism, a support mechanism fixedly connected to the bottom of the adjustment mechanism, a limiting mechanism fixedly connected to the lower end of the outer surface of the adjustment mechanism, a conveying mechanism fixedly connected to the rear end of the limiting mechanism, and a support platform mechanism symmetrically fixedly connected to the outer surface of the conveying mechanism.

[0009] Preferably, the camera mechanism includes a high-definition camera, a mounting base is fixedly connected to the top of the high-definition camera, a flash is fixedly connected to the top of the mounting base, and a mounting sleeve is fixedly connected to the bottom of the high-definition camera.

[0010] Preferably, a fixed shaft is fixedly connected to the inner surface of the fixed sleeve, and threaded shafts are fixedly connected to both the left and right ends of the fixed shaft. Threaded sleeve seats are threadedly connected to the outer surfaces of both threaded shafts, and an adjusting valve is fixedly connected to the left end of the left threaded shaft.

[0011] Preferably, the bottom of the two threaded sleeve seats is fixedly connected to a mounting base, and the bottom of the mounting base is fixedly connected to an electric telescopic rod.

[0012] Preferably, a support base is fixedly connected to the bottom of the electric telescopic rod, and a fixed base is symmetrically fixedly connected to the outer surface of the support base.

[0013] Preferably, a limiting seat is fixedly connected to the lower end of the outer surface of the electric telescopic rod one, and an electric telescopic rod two is fixedly connected to the right side of the rear end of the limiting seat.

[0014] Preferably, the conveying mechanism includes a conveyor belt, with rotating gears rotatably connected to the left and right ends of the inner side of the conveyor belt. Rotating shafts are fixedly connected to the front and rear ends of the two rotating gears. Limiting discs are fixedly connected to the outer surfaces of the four rotating shafts. Mounting bearings are rotatably connected to the outer surfaces of the opposite ends of the two rotating shafts located at the same end. The rotating shaft located at the rear left end passes through the inner surface of the mounting bearing. A drive motor is rotatably connected to the rear end of the rotating shaft located at the rear left end. The drive motor is fixedly connected to the rear side of the mounting bearing. A fixed base is fixedly connected to the bottom of the four mounting bearings.

[0015] Preferably, the support mechanism includes a sample stage, and a protective frame is fixedly connected to the outer side of each of the sample stages.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the implementation of this utility model, by setting up a conveying mechanism, it is found that most camera devices require manual placement of samples one at a time during shooting, resulting in slow shooting speed and low work efficiency. Therefore, by setting up a drive motor, the drive motor can drive the rotating gear to rotate and connect with the conveyor belt, thereby driving the support mechanism fixed on the outer surface of the conveyor belt to move forward at a uniform speed. This enables continuous and automated material conveying, improves detection efficiency, reduces manual operation, and ensures that the recycled aggregate is evenly distributed within the field of view of the high-definition camera, helping the high-definition camera to capture more comprehensive image information. The speed of the conveyor belt can be adjusted as needed so that the high-definition camera can capture defects in the aggregate at different speeds. The automated conveying device reduces the error of manual sample placement and can continuously convey multiple samples, thereby significantly improving the processing capacity of the detection device.

[0018] 2. In the implementation of this utility model, by setting up a camera mechanism, a flash is installed on the top of the high-definition camera. The flash helps to improve the clarity and quality of the image. In some cases, the ambient light may be uneven, and the flash can help balance the light, reduce shadows and overexposed areas. In non-natural light environments, the flash can help restore the true color of the subject and avoid color cast. Moreover, the instantaneous brightness of the flash can freeze the motion, which is particularly useful for shooting moving objects and can reduce blur caused by the movement of the object.

[0019] 3. In the implementation of this utility model, by setting an adjustment mechanism and rotating the adjustment valve, the vertical rotation angle of the camera mechanism can be adjusted, which helps to improve the output quality of the photographed samples.

[0020] 4. In the implementation of this utility model, by setting a limiting mechanism, the distance between the camera frame structure and the transmission mechanism can be adjusted by the extension and retraction of the electric telescopic rod two at the limiting mechanism, so as to prevent the camera frame from tilting or falling over due to external factors.

Rotating gears 505 are rotatably connected to the left and right ends of the inner side of the conveyor belt 507. Rotating shafts 503 are fixedly connected to the front and rear ends of the two rotating gears 505. Limiting discs 504 are fixedly connected to the outer surfaces of the four rotating shafts 503.

The distance between the structure at the camera mechanism 1 and the conveying mechanism 5 can be adjusted by the extension and retraction of the electric telescopic rod 402 at the limiting mechanism 4, preventing the camera mechanism 1 from tilting or tipping due to external factors. By setting a drive motor 506, the drive motor 506 can drive the rotating gear 505 to rotate and connect with the conveyor belt 507, thereby driving the support mechanism 6 fixed on the outer surface of the conveyor belt 507 to move forward at a uniform speed.
