Description

Technical Field

[0001] This utility model relates to the technical field of carbonization detection devices, and in particular to a carbonization depth measuring instrument. Background Technology

[0002] Current carbonation depth measuring instruments include a probe and a crossbar. During measurement, the probe slides, which in turn causes the crossbar to swing. The carbonation depth of the concrete is calculated by detecting the swing range of the crossbar.

[0003] Related technology can be found in Chinese Patent No. CN103353281B, which discloses a measuring device, specifically a digital carbonization depth measuring instrument. This digital carbonization depth measuring instrument includes a housing, a grating, a photoelectric sensor assembly, a display screen, and operation buttons. The housing has a lanyard hole on its upper left side, a storage battery inside the upper part of the housing, a grating below the storage battery, a photoelectric sensor assembly above the grating, a circuit board below the grating, a display screen and a microcontroller mounted on the circuit board, operation buttons below the display screen, a measurement key on the upper left side of the operation buttons, and a stylus below the operation buttons. The stylus is connected to the photoelectric sensor assembly via a swing lever, and a photoelectric switch is mounted on the swing lever. A front cover is mounted on the lower side of the housing. Its advantages are: simple structure, convenient use, safety and reliability, reduced cost of electronic components and supporting circuit boards, and the ability to directly convert displacement signals into electrical pulse signals without the instability caused by temperature drift, humidity drift, or time drift.

[0004] Regarding the aforementioned technologies, during the use of the carbonation depth measuring instrument, since concrete is being measured, a small amount of dust and oil will inevitably enter the measuring instrument during the measurement process. The measurement accuracy of the grating is highly dependent on the clarity of the optical path, and dust adhering to the surface of the grating lines will block the light, which may lead to the loss or distortion of the pulse signal.

[0022] The present application will be further described in detail below with reference to all the accompanying drawings.

[0023] This application discloses a carbonization depth measuring instrument.

[0024] Reference Figure 1 and Figure 2 A carbonization depth measuring instrument includes a housing 1, a PCB board 2 is disposed inside the housing 1, and a swing plate 11 is rotatably connected to the housing 1. One side of the swing plate 11 in the length direction is located inside the housing 1, and the other side of the swing plate 11 in the length direction is located outside the housing 1.

[0025] Reference Figure 2 and Figure 3 The swing plate 11 is located inside the housing 1 and has a swing element 12 at one end. The PCB board 2 is equipped with a sensor at the end near the swing element 12 to detect the swing stroke of the swing element 12. During detection, the side of the housing 1 with the swing plate 11 is brought close to the concrete, the swing plate 11 rotates, the swing element 12 moves, the sensor detects the stroke of the swing element 12, and thus detects the carbonation depth of the concrete. The magnetic acquisition sensor 21 is not affected by dust or oil during the detection of the swing element 12, which can effectively ensure the normal operation of the measuring instrument.

[0026] Refer to Figure 2 and Figure 4 Inside the housing 1, there is also a battery box 4, which is electrically connected to the PCB board 2. A battery is installed in the battery box 4 to power the components installed on the PCB board 2. Then, the carbonization depth can be measured using a measuring instrument.

[0027] Reference Figure 2 and Figure 5 By holding the housing 1, one end of the swing plate 11 located outside the housing 1 is brought into contact with the detection hole. The swing plate 11 is placed at the junction of carbonized and uncarbonized concrete. Then, the housing 1 is pushed to move it to a position that abuts against the concrete surface. As the housing 1 is pushed, the relative position of the housing 1 and the swing plate 11 changes.

[0028] Reference Figure 2 and Figure 3 The swing element 12 is a magnet, which is located at one end of the swing plate 11 near the PCB board 2; the sensor is a magnet acquisition sensor 21, which is installed on the side of the PCB board 2 near the swing element 12.

[0029] In this embodiment, the magnet acquisition sensor 21 is preferably a Hall effect sensor, which can detect the displacement of the magnet and thus obtain the carbonation depth of the concrete. During the measurement process, the magnet acquisition sensor 21 is not affected by dust or oil, which can effectively ensure the normal operation of the measuring instrument.

[0030] Reference Figure 2 and Figure 4The outer side of the housing 1 is provided with a display screen 3 for displaying the carbonization depth value, and the carbonization depth is displayed through the display screen 3; the battery can power the display screen 3 and the Hall effect sensor.

[0031] Reference Figure 2 and Figure 4 The housing 1 is equipped with a restorer (not shown in the figure). One end of the restorer is fixedly connected to the housing 1 along its length, and the other end of the restorer is fixedly connected to the swing plate 11 along its length. After a measurement is completed, the housing 1 is moved away from the concrete. At this time, the swing plate 11 returns to its initial position under the action of the restorer. Then the next measurement can be performed.

[0032] In this embodiment, the restoring component is preferably a restoring spring. When the swing plate 11 is compressed, the restoring spring is compressed. After the pressure on the swing plate 11 is released, the restoring spring is stretched, which can drive the swing plate 11 to restore its original state, thus providing high convenience.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
