Description

Technical Field

[0001] This utility model belongs to the field of concrete depth measurement technology, specifically, it relates to a concrete carbonation depth measurement device. Background Technology

[0002] Utility model CN212989083U relates to the field of concrete carbonation depth measurement technology, and discloses a concrete carbonation depth measuring device, including a concrete rebound hammer body. A measuring rod is arranged in the middle of the left side of the concrete rebound hammer body. Sleeve rods are fixedly arranged in the middle of the upper and lower surfaces of the concrete rebound hammer body, and guide rods pass through the two sets of sleeve rods. This utility model, by setting a flat plate and a through hole, allows the measuring rod to pass through the through hole and contact the concrete to be tested, so that a large area of ​​the flat plate contacts the outer wall of the concrete. It can be used for concrete with some surface pits and damage to ensure that the measuring rod is perpendicular to the concrete. By setting a spring, the spring tension pushes the flat plate. During the compression of the measuring rod, the flat plate and the compressed measuring rod can move synchronously. At the same time, the flat plate setting allows the operator to hold the right end of the device with one hand and press the button to save the data with one hand.

The device has errors during measurement, the user experience of the device is not good, it is not convenient for the measuring personnel to carry the device, and the use of the device is inconvenient.

The two sets of snap-fit ​​rings 31 are snapped onto the outer walls of the other two sets of first fixed rods 28. Pushing the first connecting rod 30 causes the first sleeve 29 to rotate on the first fixed rods 28, snapping the snap-fit ​​rings 31 onto the outer walls of the other two sets of first fixed rods 28, so that one outer wall of the second connecting plate 32 is in close contact with one outer wall of the second snap-fit ​​plate 25.

The measuring personnel can hang the device on their clothing through the movable buckle, making it easy to carry and retrieve.

[0031] The measuring instrument 10 uses an ABS+glass fiber reinforced composite material shell, and has three modular mounting cavities for control, measurement, and power supply. It is equipped with a main control chip STM32F103C8T6, a tungsten steel measuring stylus 12, a magnetic grating displacement sensor KTR-100, a pressure detection unit FSR402, a temperature compensation module DS18B20, and a data storage unit W25Q64JV. Its core function is to detect the carbonation depth of concrete, and it also detects ambient temperature, stylus contact pressure, and battery power. It adopts the principle of "mechanical probing + displacement detection + temperature compensation". After being positioned by the first support plate 26 and the level 33, the stepper motor drives the stylus to advance. The pressure unit identifies the carbonized and uncarbonized interface, and calculates the depth by combining displacement data and temperature correction formula. The result is transmitted to the display screen and stored.

[0032] In terms of circuit connection, the 3.7V lithium battery is powered by an LM1117-3.3V voltage regulator chip, connected in series with a self-resetting fuse and an ESD protection diode; the numerical adjustment buttons 14 (two sets) are connected to the main control PA0 / PA1 pins (pull-down resistor grounded) for adjusting the range and unit; the numerical selection buttons 15 (two sets) are connected to the PA2 / PA3 pins for confirmation and data storage; the display screen 13 is connected to the PB6 / PB7 pins via the I2C bus; the displacement sensor is connected to the PB13-15 pins via the SPI bus, the pressure unit is connected via the ADC pin PA4, and the temperature module is connected to the PB0 pin (pull-up resistor); during operation, pushing the active switch 17 to power on and initialize the device displays the calibration level; after setting parameters with the buttons, the main control drive pin advances, the sensor transmits data in real time, and the depth is calculated, displayed, and stored when there is a sudden change in pressure; when the battery is low (≤3.2V), new measurements are prohibited, only the query function is retained, and data is automatically stored before powering off.

[0033] Working principle: The measuring stylus 12 is set inside the measuring instrument 10 to measure the carbonation depth of concrete. The second snap-fit ​​plate 25 is snapped into the second snap-fit ​​groove 24, so that the first support plate 26 is in close contact with the measuring instrument 10. The outer wall of one side of the two sets of first support plates 26 can be in close contact with the outer wall of the concrete to assist in the measurement. There is also a structure composed of a second fixing plate 27, a first fixing rod 28 (a total of eight sets of second fixing plates 27 and four sets of first fixing rods 28), a first sleeve 29, a first connecting rod 30, a snap-fit ​​ring 31, and a second connecting plate 32. Pushing the first connecting rod 30 causes the first sleeve 29 to rotate on the first fixing rod 28, snapping the snap-fit ​​ring 31 into the outer wall of the other two sets of first fixing rods 28, so that the outer wall of one side of the second connecting plate 32 is in close contact with the outer wall of one side of the second snap-fit ​​plate 25 to assist in the measurement operation. The first snap-fit ​​plate 22 is snapped into the first slide groove 18, so that the first fixing plate 21 is in close contact with the inner wall of the first slide groove 18. The first limiting plate 19 is then snapped into the first limiting groove 23 (achieved by pressing the pressure plate 41) to limit the position of the first protective plate 20, thereby protecting the device. A level 33 fixedly installed in the top opening of the measuring instrument 10 helps to keep the device level during measurement. A display screen 13 fixedly installed in the top opening displays and analyzes the measurement data. Two sets of numerical adjustment buttons 14 and two sets of numerical selection buttons 15 on the top adjust the measurement values ​​of the device. An active switch 17 is slidably installed in the switch groove 16 on the other side of the outer wall. Pushing it allows it to slide inside the switch groove 16 to operate the device. Anti-slip pads 34 on both sides of the outer wall of the measuring instrument handle 11 improve the grip. The limiting band 38 is limited to the second limiting groove 35 on one side of the outer wall of the measuring instrument handle 11 by the second fixing rod 36 and the second sleeve 37. A battery compartment cover 39 is provided at the bottom of the measuring instrument 10 for battery-related operations.
