Description

Technical Field

[0001] The utility model relates to the technical field of steel bar position detection, in particular to a steel bar position detection device in a wall. Background Art

[0002] The steel bar position detection device inside a wall is a device used to determine the position of steel bars inside a wall. It emits an electromagnetic field into the wall. When the electromagnetic field encounters the steel bars, an induction signal is generated. The device receives and analyzes these induction signals to determine the position, depth and direction of the steel bars. This can help construction workers avoid damaging the steel bars during construction, ensure the safety and stability of the structure, and also help evaluate the structural condition of the building and the corrosion of the steel bars.

[0003] After searching, the Chinese patent announcement number is: CN215575718U. The application discloses a steel bar position detection device, which relates to the technical field of construction detection equipment, including a detector and a handle rod. The detector is fixed on the handle rod; the end of the detector away from the handle rod is fixedly connected to a support seat, and a ball is rotatably connected to the support seat. In the application, when the inspection personnel detect the position of the steel bars in the wall, they hold the handle rod and press the ball against the wall surface. The handle rod is moved to drive the detector to detect the position of the steel bars on the wall surface. In the process of moving the detector, the ball always presses against the wall surface and rolls, and the ball is directly connected to the wall. Contact, part of the weight of the detection device is shared by the wall, which effectively reduces the workload of the detection personnel; and the direct contact between the ball and the wall also avoids the situation where the detector is damaged by long-term friction between the detector and the wall. However, when measuring the position of the wall steel bars, although the ball is set to reduce labor and avoid wear of the detector, the rolling of the ball will cause the relative position of the detector and the wall to be unstable, thereby affecting the accuracy of the measurement, especially on the uneven wall surface, the rolling direction of the ball will change, causing the detection angle and position of the detector to shift, and then the specific position of the steel bar cannot be accurately determined, reducing the reliability of the measurement results.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Reference Figure 1 、 Figure 3 and Figure 5 , the utility model provides an embodiment: a steel bar position detection device in a wall, comprising a body 1, fixed cone nails 3 are fixedly connected at the four corners of the bottom of the body 1, and the device is stably fixed to the wall surface by the fixed cone nails 3, ensuring that the device will not shake during the detection process, thereby improving the accuracy of the detection, a plurality of detection component mounting holes 4 are opened on the front side of the bottom of the body 1 for installing the detection components, and the insides of the two fixed cone nails 3 at the rear end are fixedly connected with electromagnetic induction probes 5, which are used to generate eddy currents on the surface of the steel bars in the wall by emitting a magnetic field to detect the presence of steel bars, and the bottom ends of the two electromagnetic induction probes 5 are fixedly connected to the outside with a metal shielding layer 6, which can effectively reduce the influence of external metal materials and other interference factors on the probes, and only allow magnetic fields of a specific direction and frequency to pass through, and the outer walls of the two metal shielding layers 6 are fixedly connected with a magnetic field guide layer 7, which further guides the direction of the magnetic field to improve the eddy current signal of the steel bars. In order to improve the detection accuracy, ultrasonic probes 8 are fixedly connected to the inside of the two detection component mounting holes 4 at the front end. The ultrasonic probes 8 use the different propagation speeds of ultrasonic waves in different media to determine the position of the steel bars. A battery 9 is fixedly connected to the front side of the bottom of the fuselage 1. The battery 9 provides power support for the electromagnetic induction probe 5 and the ultrasonic probe 8. A handle 10 is fixedly connected to the top of the fuselage 1. The handle 10 is convenient for the operator to move and operate the device. A display screen 11 is fixedly connected to the top rear side of the fuselage 1. The display screen 11 is electrically connected to the two electromagnetic induction probes 5, the ultrasonic probe 8 and the battery 9 respectively, and is used to display the detection results. Through the built-in intelligent signal processing system, advanced algorithms are used to process and analyze the collected signals, distinguish between steel bar signals and interference signals, and accurately display the position information of the steel bars. A detection part protection mechanism 2 is provided at the right end of the bottom of the fuselage 1. The detection part protection mechanism 2 is used to protect the detection components to prevent them from external collision and damage.

[0040] Specifically, when using the equipment, the device is fixed to the wall surface by the fixed cone nails 3 at the four corners of the bottom of the fuselage 1 to ensure the stability of the device during the detection process. When the detection is started, the electromagnetic induction probe 5 inside the two fixed cone nails 3 at the rear end starts to work. The electromagnetic induction probe 5 generates eddy currents on the surface of the steel bars in the wall by emitting a magnetic field to detect the presence of steel bars. The metal shielding layer 6 on its outside can effectively reduce the influence of external metal materials and other interference factors on the probe, and only allows magnetic fields of specific directions and frequencies to pass through, while the magnetic field guiding layer 7 further guides the direction of the magnetic field to improve the detection accuracy of the eddy current signals generated by the steel bars. The ultrasonic probe 8 inside the two detection component mounting holes 4 at the front end also works synchronously. The ultrasonic probe 8 uses the different propagation speeds of ultrasonic waves in different media to judge the presence of steel bars. The position of the reinforcement is determined by optimizing the probe frequency and emission angle to improve the propagation efficiency and resolution of the ultrasonic wave in the wall medium. During the detection process, the battery 9 provides power support for the electromagnetic induction probe 5 and the ultrasonic probe 8.

By combining the electromagnetic induction probe 5 with the ultrasonic probe 8 and optimizing the probe design, the steel bar position can be detected more accurately, thereby improving the detection accuracy.

[0041] Reference Figure 1 、 Figure 3 and Figure 4The detection part protection mechanism 2 includes a protection cover 201, which is rotatably connected to the bottom right end of the fuselage 1. The protection cover 201 is rotatably connected to the bottom right end of the fuselage 1. It can realize the protection and opening of the detection component by rotation, which is convenient for operation and maintenance.

The right ends of the two locking pins 208 are respectively engaged with the middle parts of the two locking protrusions 202 to enhance the firmness of the protective cover 201 when it is closed.

[0042] Specifically, when the inspection is completed and the inspection part needs to be protected, the protective cover 201 is rotated to the corresponding position at the bottom right end of the fuselage 1. Since the two locking protrusions 202 at the top right end of the protective cover 201 are respectively engaged with the two locking grooves 203 at the bottom right end of the fuselage 1, the tension spring 205 is in a normal state inside the locking groove 203, and the locking pin 208 on the limit plate 206 connected to its right end is engaged with the middle of the locking protrusion 202, further fixing the position of the protective cover 201 to ensure that the inspection part is well protected. When performing the detection operation, the two pressing rods 207 are pressed, and the pressing rods 207 slide inside the installation groove 204, driving the limit plate 206 to move to the right. During the movement of the limit plate 206, on the one hand, the tension spring 205 is compressed, and on the other hand, the locking pin 208 is separated from the locking protrusion 202, so that the locking protrusion 202 is no longer restricted by the locking pin 208. It can be opened by rotating the protective cover 201. The locking structure of the protective cover 201 and the fuselage 1 prevents the detection component from being hit and damaged by the outside world, and can effectively protect the detection component from being accidentally damaged when not in use.

[0044] Specifically, multiple anti-slip strips 12 fixedly connected to the top of the handle 10 in an equidistant array can increase the friction between the operator's hand and the handle 10 to prevent the hand from slipping during operation. The switch button 13 is used to control the start and stop of the entire detection device, making it convenient for the operator to turn the device on or off, and the adjustment button 14 can be used to adjust the magnetic field strength of the electromagnetic induction probe 5 and the transmission frequency of the ultrasonic probe 8 to adapt to different detection environments and needs.

A horizontal bracket 17 is fixedly connected to the top left end of the body 1, which can provide an installation position for a spirit level 18, which is used to fix the spirit level 18. Multiple spirit levels 18 are fixedly installed inside the horizontal bracket 17, which are used to detect whether the device is installed horizontally on the wall. During the detection process, keeping the device level is very important for improving the detection accuracy. The spirit level 18 can provide the operator with an intuitive horizontal reference to help the operator adjust the position of the device to ensure the accuracy of the detection results. A weight reduction groove 19 is provided on the inner front side of the handle 10. Without affecting the overall strength and use function of the handle 10, the weight of the handle 10 is reduced, making the operator more relaxed during long-term use and reducing hand fatigue.

[0046] Specifically, the charging port 16 on the front side of the fuselage 1 is electrically connected to the battery 9, providing a charging interface for the battery 9. When the battery 9 is low on power, the operator can use the matching charger to charge the device through the charging port 16 to ensure that the detection device can continue to work normally.

The main function of the weight reduction groove 19 is to reduce the weight of the handle 10 without affecting the overall strength and use function of the handle 10, so that the operator can be more relaxed during long-term use.

[0047] Working principle: When using the equipment, the device is fixed to the wall surface through the fixed cone nails 3 at the four corners of the bottom of the fuselage 1 to ensure the stability of the device during the detection process. When the detection is started, the electromagnetic induction probe 5 inside the two fixed cone nails 3 at the rear end starts to work. The electromagnetic induction probe 5 generates eddy currents on the surface of the steel bars in the wall by emitting a magnetic field to detect the presence of steel bars. The metal shielding layer 6 on the outside can effectively reduce the influence of external metal materials and other interference factors on the probe, and only allows magnetic fields of specific directions and frequencies to pass through. The magnetic field guide layer 7 further guides the direction of the magnetic field to improve the detection accuracy of the eddy current signals generated by the steel bars. The ultrasonic probe 8 inside the two detection component mounting holes 4 at the front end also works synchronously. The probe 8 uses the different propagation speeds of ultrasound in different media to determine the location of rebars. By optimizing the probe frequency and emission angle, the propagation efficiency and resolution of ultrasound in the wall medium are improved. During the detection process, the battery 9 provides power support for the electromagnetic induction probe 5 and the ultrasonic probe 8. The handle 10 on the top of the fuselage 1 makes it convenient for the operator to move and operate the device. The detection signals obtained by the electromagnetic induction probe 5 and the ultrasonic probe 8 are transmitted to the display screen 11 on the top rear side of the fuselage 1 for display. The display screen 11 uses a built-in intelligent signal processing system and advanced algorithms to process and analyze the collected signals, distinguish between rebar signals and interference signals, and accurately display the location information of the rebar for the operator to view.

[0048] When the protective cover 201 needs to be opened for inspection, the two pressing rods 207 are pressed, and the pressing rods 207 slide inside the mounting groove 204, driving the limiting plate 206 to move to the right. During the movement of the limiting plate 206, on the one hand, the tension spring 205 is compressed, and on the other hand, the locking pin 208 is separated from the locking protrusion 202, so that the locking protrusion 202 is no longer restricted by the locking pin 208, and the protective cover 201 can be opened by rotating it.
