Description

Technical Field

[0001] The invention relates to the technical field of optical cable detectors, in particular to a telescopic optical cable routing detector. Background Art

[0002] The optical cable detector is a transmitter that generates electric and magnetic waves and transmits the transmission signal to the underground metal pipeline to be detected through different transmission connection methods. After the underground metal pipeline senses the electromagnetic wave, an induced current is generated on the surface of the underground metal pipeline. The induced current will propagate far away along the metal pipeline. During the propagation of the current, the electromagnetic wave will be radiated to the ground through the underground metal pipeline. In this way, when the optical cable route detector receiver detects on the ground, it will receive the electromagnetic wave signal on the ground just above the underground metal pipeline. The position and direction of the underground metal pipeline can be determined by the change in the strength of the received signal. Detection equipment such as optical cables can accurately detect the position, path direction, and burial depth of pipelines, pipes, cables, optical cables, etc., and can accurately identify the target cable in the middle of the complex cables, and can accurately locate the cable grounding fault. It is a master in the field of detection, truly realizing one machine for multiple uses, greatly reducing the cost of use, and the detector has an intelligent compass tracking and positioning function, which can intuitively display the position, direction and burial depth of the detected object in real time. The frequency range is wide, which can meet the needs of users with different requirements, and supports customized frequencies.

[0003] At present, the receiver of the detector is usually held by the user and moved on the ground when in use, and the position and depth of the underground optical cable are determined by the strength of the received signal.

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the present invention provides a telescopic optical cable routing detector, which has the following beneficial effects:

[0022] 1. When the present invention is in use, first turn on the transmitter, select the transmission mode from the high-definition color LCD screen, insert the wiring harness into the corresponding port of the transmitter, connect the corresponding optical cable to be tested, then turn on the receiver, select the same working mode as the transmitter from the high-definition color LCD screen, and adjust it to the same working frequency as the transmitter. After the matching is completed, the handheld receiver shakes on the surface and penetrates the signal prompt displayed on the high-definition color LCD screen on the meter head.

[0023] 2. The present invention is provided with a driving mechanism. When in use, the starting motor drives the first gear to rotate the second gear. The rotation of the second gear drives the horizontal shaft to rotate the worm. The rotation of the worm drives the worm wheel to rotate the pin shaft. The rotation of the pin shaft drives the support arm to swing. At the same time, when the support arm swings, it drives the transmission rod to make the second bevel gear roll around the first bevel gear.

The rotation of the main shaft drives the fixed block to swing the support rod. In this way, the support arm and the support rod can be retracted and extended synchronously, which is convenient for users to place the receiver of the detector on the ground for recording and other tasks during the detection process.

[0024] 3. The marking mechanism provided in the present invention, when in use, injects liquid pigment from the conduit and uses the end cap for blocking. When it is necessary to mark on the ground, turn on the power of the electromagnet to generate a magnetic pole opposite to the upper end of the strong magnetic block. At this time, the magnetic attraction overcomes the elastic force of the two springs and drives the fixed plate to move the valve needle upward. After the valve needle moves upward, the liquid pigment stored in the shell enters the rubber sleeve from the material transfer channel and is discharged and falls on the ground, so that a mark can be made on the ground. After the marking is completed, the fixed plate drives the valve needle to move down and reset under the elastic force of the spring, so that the discharge of the liquid pigment can be prevented. In addition, when the fixed plate moves up, the gas above the sealing plate in the shell is squeezed. At this time, the gas passes through the circular opening on the fixed plate to squeeze the protrusion and enter the fixed plate below the sealing plate, and the circular opening on the end cover is pushed by the elastic plate to be blocked by the protrusion, so that the gas can squeeze the pigment in the shell and discharge it quickly, and when the electromagnet switches on and off the circuit at intervals, it can play a continuous gas injection effect. When the electromagnet is powered off and the marking mechanism is not working, the elastic plate can push the protrusion to seal the circular hole, so that the pigment can be sealed and stored in the shell.

[0050] Embodiment 3: Based on embodiment 1, the difference is that;

[0051] See attached Figure 8-9The marking mechanism includes a fixed plate 27, one end of which is fixedly connected to a plurality of valve needles 25, the other end of which is fixedly connected to a strong magnetic block 28, a sealing plate 26 is fixedly connected to the housing 7, the sealing plate 26 is sleeved with the valve needles 25 through a plurality of guide holes, the upper end of the sealing plate 26 is fixedly connected to two guide rods 30, the side walls of the end cover and the fixed plate 27 are sleeved with the rod walls of the two guide rods 30 through the guide holes, the rod walls of the guide rods 30 are sleeved with springs 31, and the springs 32 are sleeved with the guide rods 30. One end of the spring 31 is fixedly connected to the upper end of the fixing plate 27, and the other end of the spring 31 is fixedly connected to the lower end of the end cover. A plurality of rubber sleeves 23 are installed at the lower end of the housing 4. The plurality of rubber sleeves 23 are respectively sleeved on the side walls of the plurality of valve needles 25. The side walls of the rubber sleeves 23 are penetrated to form two material passages 24. A rectangular opening is provided at the upper end of the housing 7. The end cover is fixedly connected to the rectangular opening by bolts. The side wall of the end cover is fixedly connected to an electromagnet 29. The electromagnet 29 is located at the upper end of the strong magnetic block 28.

[0052] The side walls of the end cover and the fixing plate 27 are vertically provided with circular openings 19, and elastic plates 21 are arranged at the open lower ends of the two circular openings 19. One ends of the two elastic plates 21 are respectively fixedly connected to the lower ends of the end cover and the fixing plate 27 by rivets. A hemispherical protrusion 20 is arranged on one side of the elastic plate 21, and one side of the protrusion 20 is located in the circular opening 19.
