The invention is further described below with reference to examples.
Examples: referring to fig. 1 to 11, a coaxial radio-frequency cable energizing detection device comprises a base 1, a control unit 2 arranged on the side surface of the base 1, a first rotating disc 3 and a second rotating disc 4 which are arranged on the upper surface of the control unit 2 in a rotating manner from top to bottom, a detection disc 5 arranged above the base 1, a spiral groove 6 arranged on the upper surface of the detection disc 5, two rotating rods 7 arranged in the center of the detection disc 5, a detection assembly 9 movably connected to the rotating rods 7, a driving piece arranged in the base 1 and corresponding to the position of the second rotating disc 4 and used for driving the first rotating disc 3 and the second rotating disc 4 to rotate, an adjusting assembly 8 arranged in the base 1 and corresponding to the position of the driving piece and used for switching the rotating states of the first rotating disc 3 and the second rotating disc 4 and the working states of the detection assembly 9, and an auxiliary assembly 19 arranged in the base 1 and corresponding to the position of the adjusting assembly 8;
the detection assembly 9 comprises a sliding block 91 which is connected to the side face of the rotating rod 7 in a sliding mode, a current clamp 92 is elastically and slidably connected to the inner side face of the sliding block 91, through holes 93 used for communicating the rotating rod 7 with the sliding block 91 are uniformly formed in the inner bottom face of the rotating rod 7, a first magnet 94 is mounted at the position, corresponding to the through holes 93, of the inner side face of the sliding block 91, a second magnet 95 is elastically connected to the position, corresponding to the through holes 93, of the inner top face of the rotating rod 7, and the magnetism of the surface, close to the first magnet 94, of the second magnet 95 is identical.
When the coaxial radio frequency cable is detected, one end of the cable is fixed on the side face of the second rotary table 4, the cable is placed at the inlet end of the spiral groove 6, the cable is coiled on the spiral track of the spiral groove 6 from outside to inside in sequence, after coiling is completed, the end part of the cable is pulled out from the outlet end on the spiral groove 6, and the end part of the cable at the outlet end is pulled and fixed on the surface of the first rotary table 3, so that the cable installation work is completed;
referring to fig. 3 to 5, the driving part comprises a first rotating rod 10, a first rotating rod 10 is fixedly installed on the top surface of the first rotating disc 3, a second rotating rod 11 fixedly connected with the second rotating disc 4 is sleeved on the side surface of the first rotating rod 10 corresponding to the position of the second rotating disc 4, a first bevel gear 12 is installed at the lower end of the second rotating rod 11, a second bevel gear 14 is installed on the side surface of the first rotating rod 10 near the lower part of the first bevel gear 12, the first bevel gear 12 and the second bevel gear 14 are in meshed connection through a third bevel gear 15, the third bevel gear 15 is sequentially connected with the first rotating rod 10, the second rotating rod 11 and the inner side surface of the base 1 through a connecting frame, a second gear 18 is rotatably installed on the side surface of the first rotating rod 10 near the lower part of the second bevel gear 14, a first gear 17 is connected with the inner bottom surface of the base 1 corresponding to the position of the second gear 18 through the third rotating rod 16, and the lower end of the first gear 17 extends to the outside of the base 1 and is connected with an output shaft of an external motor;
further, an external motor is turned on, an output shaft of the motor drives a third rotating rod 16 to rotate, the third rotating rod 16 drives a second gear 18 to rotate through transmission between a first gear 17 and a second gear 18, and the second gear 18 drives a first rotating disc 3 to rotate through a first rotating rod 10; it should be noted that when the first rotating rod 10 rotates, the first bevel gear 12 is driven to rotate through the transmission between the second bevel gear 14 and the third bevel gear 15, when the first bevel gear 12 rotates, the second rotating disc 4 is driven to rotate through the second rotating rod 11, and when the second bevel gear 14 drives the first bevel gear 12 to rotate through the third bevel gear 15, the third bevel gear 15 is that the rotation directions of the first bevel gear 12 and the second bevel gear 14 are opposite, when the first rotating disc 3 and the second rotating disc 4 rotate, the rotation directions of the first rotating disc 3 and the second rotating disc 4 are opposite, so that one of the second rotating disc 4 and the first rotating disc 3 achieves the purpose of collecting cables when rotating, one of the second rotating disc 4 and the first rotating disc 3 achieves the purpose of discharging the cables when rotating, and the purpose of moving the cables along the spiral track when the cables move in the spiral groove 6 through one collecting and releasing, thereby facilitating the subsequent detection work;
when the coaxial radio frequency cable is electrified and detected, one rotating rod 7 is rotated by manpower to enable the end part of the rotating rod to be positioned close to the inlet end of the spiral groove 6, then the detecting assembly 9 is moved by manpower to enable the rotating rod to be positioned corresponding to the spiral groove 6, as the lower part of the current clamp 92 is provided with an opening, the cable is positioned in the current clamp 92 by pressing the current clamp 92, and similarly, the other rotating rod 7 is rotated to enable the cable to be positioned close to the outlet end of the spiral groove 6, so that the cable is wrapped; the current clamp 92 operates on the principle of indirectly measuring the current in the ac circuit by means of an induced electromagnetic field and measuring the induced electromotive force.
At this time, an alternating current is supplied to the inside of the current clamp 92 through the control unit 2, and an induced fault current having a direction opposite to that of the current clamp 92 is generated in the inside of the current clamp 92 due to the electromagnetic induction, which is based on the principle of faraday's law of electromagnetic induction: the varying magnetic field creates an induced electromotive force in the closed loop, thereby driving electrons to flow to form a current, and also forms a closed loop in the cable near the current clamp 92, which is not described herein in detail for the prior art; when the current in the current clamp 92 changes, a changing magnetic field is generated, and then a current is induced in the cable, and when the cable is electrified normally, the current can be transmitted to the other current clamp 92 through the current, so that the effect that one current clamp 92 generates a current, and the current clamp 92 receives the current is achieved, when the current fails, the interior of the current clamp 92 receiving the current does not receive the current, and therefore whether the coaxial radio-frequency cable is electrified normally can be judged through whether the current exists in the current clamp 92 receiving the current;
through coiling the cable in the detection mode in the spiral groove 6, on one hand, the degree of single detection of the cable is increased, the detection efficiency is improved, on the other hand, when the cable breaks down, an operator can detect the cable gradually along the path of the spiral groove 6 by rotating the rotary rod 7 positioned at the inlet end of the spiral groove 6 and moving the position of the detection assembly 9, the degree of detection of the cable is gradually reduced, the position of the cable at which the fault occurs is gradually determined, the position of a disconnection point of the cable is further detected, the utilization of the cable at a continuous part is facilitated, and the problem of resource waste is avoided;
referring to fig. 3 and 7, the moving member further includes a reciprocating screw 815 inserted on the third rotating rod 16 at a position corresponding to the first extrusion block 88, and a movable block 816 is screwed on a side surface of the reciprocating screw 815;
further, when the third rotating rod 16 rotates, the reciprocating screw 815 is driven to rotate, and the reciprocating screw 815 is usually used for converting the rotation motion into the linear motion or converting the direction of the force. It consists of a screw rod with a spiral shape and a nut. The screw is a threaded shaft, generally cylindrical in shape, with the threads on the surface aligned parallel to the axis. The nut is a part matched with the screw thread of the screw rod and can slide along the thread line on the screw rod. When the screw rod rotates, the nut moves along the axial direction of the screw rod due to the slope of the thread, so that reciprocating linear motion is realized, which is not described in detail herein in the prior art, and the movable block 816 is driven to move up and down when the reciprocating screw rod 815 rotates;
the movable part comprises a movable groove 86 which is arranged in the base 1 and corresponds to the position of the connecting hole 81, and the inner side surface of the movable groove 86 is connected with a first extrusion block 88 through a first elastic air bag 87;
the detection assembly 9 further comprises a second elastic air bag 810 which is arranged in the base 1 and corresponds to the lower end position of the reciprocating screw 815, a second extrusion block 89 is connected to the position, corresponding to the movable block 816, of the side face of the second elastic air bag 810, a first connecting pipe 811 is connected to the side face of the second elastic air bag 810, a second connecting pipe 812 is connected to the center of the detection disc 5, the detection disc 5 is communicated with the rotary rod 7 through the second connecting pipe 812, and one end, far away from the second elastic air bag 810, of the first connecting pipe 811 extends to a position close to the second connecting pipe 812 and is communicated and connected with the second connecting pipe 812;
as shown in fig. 3 and fig. 5, in the initial state, the movable block 816 is located at a position close to the second extrusion block 89, when the reciprocating screw 815 rotates, the movable block 816 is driven to move in a direction close to the second extrusion block 89, the second extrusion block 89 extrudes the second extrusion block 89, the extrusion force makes the second extrusion block 89 move in a direction close to the second elastic air bag 810 and gradually extrudes the second elastic air bag 810, and the extrusion force makes gas in the second elastic air bag 810 enter into the rotary rod 7 through the first connecting pipe 811 and the second connecting pipe 812;
it is noted that, after the position adjustment of the current clamp 92 on the rotating rod 7 is completed, the position of the sliding block 91 corresponds to the position of one of the second magnets 95 on the rotating rod 7, at this time, the two corresponding second magnets 95 and the first magnet 94 generate repulsive force, the repulsive force makes the second magnet 95 move away from the through hole 93 against the elastic force between the rotating rod 7, a gap is generated between the second magnet 95 and the through hole 93, and a gap is not generated between the other through holes 93 and the second magnet 95, so that the problem that gas leakage affects the gas extrusion is avoided, and the stability of the detection work is ensured;
it should be noted that after the gas in the second elastic air bag 810 enters the rotating rod 7, the gas enters the sliding block 91 through the gap between the second magnet 95 and the through hole 93 to squeeze the current clamp 92, the squeezing force makes the current clamp 92 move towards the direction close to the cable in the spiral groove 6, since the lower part of the current clamp 92 is provided with an opening and the opening is provided with an elastic layer, the opening is in a closed state through the elastic layer, which is not described in detail herein, when the cable is squeezed by the lower part of the current clamp 92, the cable overcomes the elasticity of the elastic layer at the opening of the current clamp 92 and enters the interior of the current clamp 92, the connection between the current clamp 92 and the cable is completed, and the connection between the two current clamps 92 and the cable is completed in the same way, and it should be noted that the two current clamps 92 are conveniently located at the opening end and the entrance end of the spiral groove 6, after the connection between the two current clamps 92 and the cable is completed, the current clamp 92 is normally electrified if the current is received, and the fault is not occurred in the current clamp 92;
