[0029] The stretching mechanism 3 is movably mounted at the bottom of the detection frame 1. Three alarms 9 are equidistantly mounted at the bottom right of the detection frame 1. The alarms 9 are electrically connected to the battery 7 via wires.

[0030] The trigger mechanism 8 is movably mounted on the upper end of the detection frame 1 , a fixed docking mechanism 4 is mounted on the upper right end of the detection frame 1 , and a guiding mechanism 6 is movably mounted on one side of the trigger mechanism 8 on the upper end of the detection frame 1 .

[0031] The stretching mechanism 3 includes a movable rope 301, a mounting spring 302, and a movable block 303. The movable block 303 is movably mounted in the middle of the inner cavity of the detection frame 1. Several mounting springs 302 are bolted to the right side of the bottom end of the movable block 303 and the bottom end of the detection frame 1. The movable rope 301 is fixedly mounted in the middle of the left side of the bottom end of the movable block 303. The movable block 303 has a rectangular structure when viewed from above.

[0032] A connection hole is provided on the left side of the bottom end of the detection frame 1, opposite to the movable rope 301. The mounting spring 302 is supported by spring steel. A reinforcing rib layer 10 is welded to the left side of the detection frame 1. The detection frame 1 has a rectangular structure when viewed from the side. The bottom end of the movable rope 301 passes through the bottom end of the detection frame 1 and extends outside the detection frame 1.

[0033] The detection mechanism 2 includes an electromagnetic block 201, a movable plate 202 and an iron sheet 203. The movable plate 202 is mounted at the bottom end of the movable rope 301 by bolts, the electromagnetic block 201 is mounted on the middle of the right side of the movable plate 202 by bolts, and the iron sheet 203 is mounted on the left side of the movable plate 202 by bolts. The movable plate 202 and the iron sheet 203 are both circular structures when viewed from the side. The electromagnetic block 201 is electrically connected to the battery 7 through a wire. A switch is installed on the outside of the electromagnetic block 201. In this way, when performing a test, the electromagnetic block 201 is first started to make the iron sheet 203 magnetic, and then the movable plate 202 is moved to the position to be tested through the detection frame 1. The magnetism of the iron sheet 203 will generate magnetic attraction with the metal material inside the concrete, and then the detection frame 1 is pushed upward to drive the movable plate 202 and the iron sheet 203 to move;

A sliding hole 13 is provided in the middle of the bottom end of the trigger tube 804. The movable round rod 802 moves downward, and drives the guide ring 801 to move downward. When the guide ring 801 continues to move downward and contacts the guide block 803 at the upper end, the front alarm 9 will be activated and the inspector will be informed that the metal fiber distribution density exceeds the standard. When the movable round rod 802 and the guide ring 801 continue to move downward, they will contact the guide block 803 in the middle and simultaneously activate the alarm 9 in the middle, informing the inspector that the metal fiber distribution density is heavy. If the movable round rod 802 is completely fitted into the trigger tube 804, the guide ring 801 will contact the guide blocks 803 at the upper, middle and bottom ends at the same time, and three alarms 9 will be activated at the same time, directly informing the inspector that the metal fiber distribution density at the bottom end of the concrete object has seriously exceeded the standard, and different classifications can be performed directly by triggering different alarms 9.

[0036] The drainage mechanism 6 includes a mounting cylinder 601, a porous jet plate 602, a moving block 603, a connecting air pipe 604, an extrusion air bag 605 and a connecting rod 606. The mounting cylinder 601 is mounted on the upper middle part of the right side of the detection frame 1 by means of bolts. The moving block 603 is movably mounted on the upper inner end of the mounting cylinder 601. The extrusion air bag 605 is mounted on the bottom end of the moving block 603 and the bottom inner end of the mounting cylinder 601 by means of bolts. The connecting rod 606 is mounted on the left bottom end of the moving block 603 by means of bolts. The bottom end of the connecting rod 606 is connected to the top of the movable block 303 by means of bolts. The connecting air pipe 604 is mounted on the right bottom end of the extrusion air bag 605 by means of bonding. The air plate 602 is mounted on the upper right end of the mounting tube 601 by means of bolts, and the upper end of the connecting air pipe 604 is connected to the lower left end of the porous air jet plate 602 by means of bolts. Thus, when the movable block 303 moves downward, it drives the connecting rod 606 downward, and drives the movable block 603 downward, thereby squeezing the extrusion air bag 605, and transporting the air inside the extrusion air bag 605 to the inside of the porous air jet plate 602 through the connecting air pipe 604. The air is then directly sprayed onto the outside of the battery 7 through the porous air jet plate 602, thereby cooling the battery 7 and preventing the battery 7 from overheating due to long-term use, thereby reducing its lifespan in later use.

[0037] The fixed docking mechanism 4 includes a docking ring 401 and an extrusion layer 402. The docking ring 401 is installed on the upper middle end of the right side of the detection frame 1 by bolts, and the extrusion layer 402 is installed inside the docking ring 401 by bonding. The extrusion layer 402 is made of rubber material. A stop bar is installed on the top of the docking ring 401 by bolts, and a cleaning ring 11 is installed on the top of the trigger cylinder 804 by bolts. A cleaning brush 12 is installed around the inside of the cleaning ring 11 by bolts. In this way, when the moving rod 802 moves, the outside of the moving rod 802 will contact and rub against the inside of the cleaning brush 12, and the outside of the moving rod 802 and the guide ring 801 will be cleaned to prevent impurities from accumulating on the outside of the guide ring 801 and causing poor contact.

[0038] Working principle: When the present invention is conducting detection, the electromagnetic block 201 is first started to make the iron sheet 203 magnetic, and then the movable plate 202 is moved to the position to be detected through the detection frame 1. The magnetism of the iron sheet 203 will generate magnetic attraction with the metal material inside the concrete, and then the detection frame 1 is pushed upward to drive the movable plate 202 and the iron sheet 203 to move. When the metal fiber density at the bottom end of the concrete object is large, the magnetic attraction will be greater, and the movable block 303 will be driven to move downward through the movable rope 301, and the installation spring 302 will be squeezed during the movement. When moving, the movable round rod 802 will be driven downward through the movable rod 805, and the guide ring 801 will be driven downward. When the guide ring 801 continues to move downward and contacts the guide block 803 at the upper end, the front side alarm 9 will be activated to tell the detection personnel that the metal fiber distribution density exceeds the standard, and when moving, the movable round rod 802 and the guide ring 801 continue to move downward, and they will contact the guide block 8 in the middle. 03 contact, and simultaneously activate the alarm 9 in the middle, telling the inspection personnel that the metal fiber distribution density is heavy. If the movable round rod 802 is completely embedded in the trigger tube 804, the guide ring 801 will contact the guide blocks 803 at the upper end, the middle end and the bottom end at the same time, and activate the three alarms 9 at the same time, which will directly tell the inspection personnel that the metal fiber distribution density at the bottom end of the concrete object has seriously exceeded the standard. Different levels are directly triggered by triggering different alarms 9, and the size and level of the metal density distribution inside the concrete can be intuitively told to the staff during the inspection process, and the inspection personnel can directly record it. It is also convenient to carry and use, and there will be no technical difficulty in operation. It prevents the inspection equipment from being enlarged or requiring technical requirements for operation during the inspection process, and it cannot be directly observed during the inspection process. If the inspection exceeds the standard, what level it will be cannot be intuitively observed at the first time, and the recording is not fast enough.

[0039] At the same time, when pushing the detection frame 1 to move, one end of the external long rod can be brought into contact with the inside of the docking ring 401. When the long rod is located inside the docking ring 401, it will squeeze the extrusion layer 402. The reaction force of the extrusion layer 402 fixes the long rod in use and drives the detection frame 1 to move. When the position to be detected is higher, moving it with the long rod is more labor-saving, and fixing it is also faster and more convenient.

[0040] When the movable block 303 moves downward, it will drive the connecting rod 606 to move downward, and drive the movable block 603 to move downward, which will squeeze the extrusion airbag 605, and transport the air inside the extrusion airbag 605 to the inside of the porous jet plate 602 through the connecting air pipe 604, and directly spray it to the outside of the battery 7 through the porous jet plate 602, so as to cool the battery 7 and prevent the battery 7 from being overheated due to long-term use, thereby reducing its lifespan during later use.
