Description

Technical Field

[0001] The present invention relates to the field of network signal testing, and specifically to a bionic network cable signal testing robot. Background Art

[0002] With the rapid development of 5G networks and Internet of Things technologies, the scale of network infrastructure has grown exponentially. According to statistics, the annual increase in the length of network cables globally exceeds 5 million kilometers, of which 30% are deployed in hard-to-reach areas such as high altitudes and underground pipelines. Traditional network cable testing, including fiber optic and network cable testing, usually relies on manual handheld devices for detection. Manual efficiency is low, and long-distance cables need to be segmented, which is time-consuming and prone to missing fault points. Therefore, a bionic network cable signal testing robot is needed to replace the existing network signal testing devices. Summary of the Invention

[0003] The purpose of the present invention is to provide a bionic network cable signal testing robot to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A bionic network cable signal testing robot, including a testing robot, the testing robot is provided with two symmetric front and rear square grooves, and a frame is fixedly connected in each square groove. The frame and the left and right end walls of the square groove are rotatably connected with a first threaded shaft. Two threaded blocks are slidably connected left and right in the square groove. The threaded blocks are fixedly connected with a first connecting frame. The first connecting frame is rotatably connected with a first rotating frame. The other end of the first rotating frame is rotatably connected with a second rotating frame. The second rotating frame is fixedly connected with a locking block. A dual-axis motor is fixedly connected in the locking block. The dual-axis motor is power-connected with two symmetric front and rear second threaded shafts. Two symmetric front and rear threaded plates are slidably connected in the locking block. The threaded plates are threadedly connected with the second threaded shafts, and the threaded plates are fixedly connected with semi-circular plates. The two locking blocks are symmetric front and rear. The semi-circular plates clamp the cable. Thus, after rotating the first rotating frame and the second rotating frame, the semi-circular plates are adjusted to a suitable position, and the dual-axis motor is used to drive the semi-circular plates to clamp the cable. Furthermore, after the cable is clamped by the two sets of staggered semi-circular plates, the other two sets of semi-circular plates slightly loosen the cable, and then under the rotation of the corresponding first threaded shaft, they are translated, and by alternately clamping and translating, the movement of an animal can be mimicked on the cable.

[0005] A top plate is fixedly connected to the upper end surface of the test robot. The top plate is provided with four round holes. Below each round hole, there is a side plate fixedly connected to the test robot. The side plate is rotatably connected with a propeller located in the round hole. The propeller is coaxially aligned with the round hole. Each second rotating frame is fixedly connected with a second connecting frame. The second connecting frame is rotatably connected with a second rotating block. The upper end surface of the second rotating block is fixedly connected with a rod cylinder. Above each second rotating frame, there is a sliding rod frame fixedly connected to the lower end surface of the test robot. The sliding rod frame is slidably and rotatably connected with a first rotating block. The lower end surface of the first rotating block is fixedly connected with a long rod. The long rod is inserted into the rod cylinder and is slidably connected with the rod cylinder. A spring is fixedly connected between the first rotating block and the second rotating block, so as to support the first rotating frame and the test robot through the spring, avoid the motor being damaged by long-term torsion, and at the same time keep the test robot in a vertical state by rotating the propeller to avoid tilting.

[0006] Preferably, the test robot is provided with a square hole. A bottom plate is fixedly connected inside the square hole. An electric push rod is fixedly connected to the lower end surface of the bottom plate. The electric push rod is power-connected to a laser marking machine. The laser marking machine can perform laser engraving. Thus, when a fault of the cable is detected, the laser marking machine is driven to move down by the electric push rod, and the laser marking machine is used to print a two-dimensional code at the fault position of the cable, which is convenient for the staff to know the fault type and locate the fault position conveniently by scanning during maintenance.

[0007] Preferably, two second motors are fixedly connected inside each frame. The second motor is power-connected to the first threaded shaft. The second motor can drive the first threaded shaft to rotate. The test robot is fixedly connected with two cover plates covering the square groove. The first connecting frame extends out of the cover plate, so that the cover plates protect the workpiece inside the first threaded shaft.

[0008] Preferably, each first connecting frame is fixedly connected with a third motor. The third motor is power-connected to the first rotating frame. The third motor can drive the first rotating frame to rotate. Each first rotating frame is fixedly connected with a fourth motor. The second rotating block is power-connected to the second rotating frame. The fourth motor can drive the second rotating frame to rotate. Two connecting rods are fixedly connected between each locking block and the second rotating frame.

[0009] Preferably, two limiting rods are fixedly connected to the left and right end walls of the frame and the square groove. The limiting rods are slidably connected with the threaded block, so as to improve the stability of the movement of the threaded block.

[0010] Preferably, a first motor is fixedly connected to the lower end surface of each side plate. The first motor is power-connected to the propeller and can drive the propeller to rotate.

[0011] Preferably, an electromagnetic detector is fixedly connected inside the test robot. The electromagnetic detector can detect cable signal problems without the outer skin of the glass cable through an internally installed high-frequency eddy current sensor.

[0012] Preferably, an intelligent controller is fixedly connected inside the test robot. The intelligent controller controls all motors, the electric push rod, the laser marking machine, and the electromagnetic detector, and is powered by a storage battery fixedly connected inside the test robot.

[0013] Preferably, an image sensor is fixedly connected to the right end surface of the test robot. The image sensor conducts image monitoring to judge whether there are obstacles and whether it has reached the utility pole.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] In the present invention, by setting a first threaded shaft, a first rotating frame, and a semi-circular plate, the third motor drives the first rotating frame to rotate, and the fourth motor drives the second rotating frame to rotate. After placing the semi-circular plates on both sides of the cable, the biaxial motor drives the two semi-circular plates to clamp the cable. The cable is clamped by two sets of staggered semi-circular plates. After the other two sets of semi-circular plates are slightly loosened, the corresponding first threaded shaft rotates to drive the threaded block to move, and then the two loosened locking blocks are translated forward along the cable and clamped again. By alternately imitating the walking of animals on the cable in this way, stable movement detection on the cable can be achieved.

[0016] In the present invention, by setting a top plate, a spring, and an image sensor, the image sensor is used to judge the forward direction, and to judge whether there are obstacles and the position of the utility pole. The rotation of the propeller is used to prevent the test robot from tilting and maintain a vertical traveling state. The spring supports and shock-absorbs the test robot, greatly reducing the torque on the motor when it is not working, and further improving the temperature stability of the robot's movement.

[0037] Embodiment 3:

[0038] Please refer to Figures 1-9 , in order to timely mark the detected fault positions and types, an electric push rod 105 and a laser marking machine 106 are provided;

[0039] The test robot 100 is provided with a square hole 117. A bottom plate 118 is fixedly connected inside the square hole 117. An electric push rod 105 is fixedly connected to the lower end surface of the bottom plate 118. The electric push rod 105 is power-connected to a laser marking machine 106. When a fault of the cable 113 is detected, the laser marking machine 106 can perform laser engraving. The electric push rod 105 drives the laser marking machine 106 to move downward, and the laser marking machine 106 prints a two-dimensional code at the fault position of the cable 113 by using laser, which is convenient for the staff to know the fault type and locate the fault position conveniently by scanning during maintenance;

[0042] An image sensor 107 is fixedly connected to the right end face of the test robot 100. The image sensor 107 performs image monitoring to judge whether there are obstacles and whether it reaches the pole.

[0043] Working principle:

[0044] First, hold the device and use the intelligent controller 115 to control the third motor 137 to drive the first rotating frame 101 to rotate, and cooperate with the fourth motor 139 to drive the second rotating frame 102 to rotate, so as to rotate the four groups of semi-circular plates 104 to the position of the cable 113, and the four electromagnetic detectors 114 are coaxially aligned. Start the double-shaft motor 132 to drive the second threaded shaft 134 to rotate to clamp the cable 113 with the semi-circular plates 104. At the same time, start the first motor 112, and the first motor 112 drives the propeller 111 to rotate. The rotation of the propeller 111 keeps the test robot 100 in a vertical state all the time, avoiding tilting, and at the same time reducing the pressure on the first rotating frame 101 and the second rotating frame 102. Cooperating with the relative sliding of the rod cylinder 128 and the long rod 127 and the telescoping of the spring 131, further reduce the torque on the third motor 137 and the fourth motor 139, avoiding damage to the motors caused by long-term large torque. When moving, by loosening two sets of staggered semi-circular plates 104 and keeping the other two sets of semi-circular plates 104 clamped, the second motor 136 corresponding to the slightly loosened semi-circular plates 104 drives the first threaded shaft 120 to rotate. The rotation of the first threaded shaft 120 drives the corresponding threaded block 119 to translate, and the threaded block 119 drives the corresponding first rotating frame 101 and the second rotating frame 102 to translate, so as to drive the test robot 100 to move horizontally along the cable 113. The staggered semi-circular plates 104 alternately clamp and slightly loosen, enabling the test robot 100 to move smoothly along the cable 113 by imitating the movement mode of animals on the cable.

[0045] When the electromagnetic detector 114 detects a signal problem with the cable 113, stop the test robot 100 and make the four groups of semi-circular plates 104 clamp the cable 113. Then start the electric push rod 105, and the electric push rod 105 drives the laser marking machine 106 to move down to the upper side of the cable 113. Use the laser marking machine 106 to laser-print a two-dimensional code on the faulty position of the cable 113. The type of the fault is recorded in the two-dimensional code, so that the maintenance personnel can conveniently scan the code to know the type of the fault and better locate the position of the fault, and cooperate with the image sensor 107 to detect whether there are obstacles on the forward route and whether it reaches the pole position.
