Description

Technical Field

[0001] The utility model relates to a multi-mode RTK-assisted cable path identification instrument, belonging to the technical field of surveying and mapping auxiliary equipment. Background Art

[0002] With the widespread use of power cables in power grids, the number of cables has also increased. It is crucial to accurately determine the location of cables, which has an important impact on cable maintenance, repair and planning. Traditional cable path identification instruments can detect the approximate location of underground cables, but most instruments do not have GNSS positioning capabilities.

[0003] In the prior art, there are methods that use GPS to assist in positioning, but the signal coverage and positioning accuracy of GPS in specific areas (such as urban canyons, dense forest areas, etc.) are limited. Therefore, a more accurate positioning method is needed to assist the cable path identifier. In the prior art, an RTK module is usually selected for auxiliary identification, but the bracket of the RTK module is cumbersome to operate and cannot be quickly installed and disassembled.

[0004] A portable cable identification device based on RTK technology disclosed in a Chinese utility model patent with publication number CN218896181U includes a cable identification device receiver and a receiver bracket. The cable identification device receiver is equipped with an RTK module; the receiver bracket is equipped with a human body connector so that the receiver bracket can be worn on the human body.

[0005] The above reference example clamps the cable identifier and the receiver bracket together, but still requires a certain amount of force to be applied for adjustment and alignment, and the mechanical clamping structure may also become fatigued and damaged, so improvement is urgently needed. Utility Model Content

[0006] In order to overcome the shortcomings of the existing RTK module bracket and cable path identifier that cannot be quickly installed and disassembled, and the mechanical clamping will have the risk of fatigue and damage, the utility model designs a multi-mode RTK-assisted cable path identifier, which can realize the rapid installation and disassembly of the RTK module bracket and the cable path identifier, saves time and labor, and has strong applicability.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A multi-mode RTK-assisted cable path identification instrument comprises an identification instrument body, a mounting bracket and an RTK module. A plurality of magnetic suction cups are fixed on one side of the mounting bracket, the magnetic suction cups are magnetically connected to the identification instrument body, and the other side of the mounting bracket is detachably connected to the RTK module.

[0009] Furthermore, at least two clamping units are installed on the mounting bracket, and the clamping unit includes an electromagnet and a pair of clamping claws. The electromagnet is longitudinally embedded in the mounting bracket, and sliding cavities are provided on both sides of the electromagnet and are transversely opened in the mounting bracket. The two clamping claws are slidably installed in the two sliding cavities one by one, one end of the clamping claw is magnetically connected to the electromagnet, and the other end extends out of the sliding cavity to clamp the RTK module.

[0010] Furthermore, the top of one end of the clamping claw extending out of the sliding cavity is integrally connected with a clamping bevel block, and the free ends of the two opposite clamping bevel blocks are inclined toward each other; a pressure detection plate is fitted and fixed to the top of the clamping bevel block, and a control panel is arranged inside the mounting bracket, and the control panel is electrically connected to the pressure detection plate and the electromagnet respectively. When the pressure detected by the pressure detection plate is greater than the preset pressure value, the control panel controls the electromagnet to lose power.

[0011] Furthermore, a switch is provided between the control panel and the pressure detection plate.

[0012] Furthermore, one end of the clamping claw disposed inside the sliding cavity is T-shaped.

[0013] Furthermore, the clamping jaw is an elastic clamping jaw.

[0014] Furthermore, a rubber anti-slip pad is provided on one side of the clamping jaw for clamping.

[0015] Furthermore, four magnetic suction cups are provided, and the four magnetic suction cups are distributed in a rectangular shape.

[0016] Compared with the prior art, the utility model has the following characteristics and beneficial effects:

[0017] The utility model ensures the stability of the identification instrument body during use by magnetic connection between the magnetic suction cup and the identification instrument body, which is not easy to loosen or fall off, thereby improving the reliability and stability of the identification instrument body. At the same time, compared with mechanical clamping, the operation through magnetic connection is more convenient. It is only necessary to fit the magnetic suction cup and the identification instrument body. There is no need for any additional operation, manual adjustment or force application, and the connection speed is faster. Especially in the case of frequent disassembly, a lot of time can be saved, and the magnetic connection usually does not require additional maintenance, there is no need to worry about fatigue damage, and the service life is long.

[0023] The present invention will be described in more detail below in conjunction with the embodiments.

[0024] Embodiment 1

[0025] See also Figure 1 and Figure 2 The multi-mode RTK-assisted cable path identification instrument of this embodiment includes an identification instrument body 1, a mounting bracket 4 and an RTK module 5. A plurality of magnetic suction cups 2 are fixed on one side of the mounting bracket 4, and the magnetic suction cups 2 are magnetically connected to the identification instrument body 1. The other side of the mounting bracket 4 is detachably connected to the RTK module 5.

[0026] From the above description, it can be seen that the beneficial effect of the utility model is that the magnetic connection between the magnetic suction cup 2 and the identification instrument body 1 ensures the stability of the identification instrument body 1 during use, and it is not easy to loosen or fall off, thereby improving the reliability and stability of the identification instrument body 1. At the same time, compared with mechanical clip-on, the operation through magnetic connection is more convenient. It is only necessary to fit the magnetic suction cup 2 and the identification instrument body 1. There is no need for any additional operation, manual adjustment or force application, and the connection speed is faster, especially in the case of frequent disassembly, which can save a lot of time, and the magnetic connection usually does not require additional maintenance, there is no need to worry about fatigue damage, and the service life is long.

[0027] Furthermore, the clamp 3 is an elastic clamp, which is suitable for RTK modules 5 of various models and sizes.

[0028] Furthermore, a rubber anti-slip pad is provided on one side of the clamping jaw 3 for clamping to ensure a secure clamping.

[0029] Furthermore, four magnetic suction cups 2 are provided, and the four magnetic suction cups 2 are distributed in a rectangular shape, so that the acceptance is more uniform and the clamping is more stable.

[0030] Embodiment 2

[0031] The multi-mode RTK-assisted cable path identification instrument of this embodiment includes an identification instrument body 1, a mounting bracket 4 and an RTK module 5. A plurality of magnetic suction cups 2 are fixed to one side of the mounting bracket 4, and the magnetic suction cups 2 are magnetically connected to the identification instrument body 1. The other side of the mounting bracket 4 is detachably connected to the RTK module 5.

[0032] Specifically, two clamping units are installed on the mounting bracket 4, and the clamping unit includes an electromagnet 7 and a pair of clamping claws 3. The electromagnet 7 is longitudinally embedded in the mounting bracket 4, and sliding cavities 10 are arranged on both sides of the electromagnet 7 and are transversely opened in the mounting bracket 4. The two clamping claws 3 are slidably installed in the two sliding cavities 10 in a one-to-one manner. One end of the clamping claw 3 is magnetically connected to the electromagnet 7, and the other end extends out of the sliding cavity 10 to clamp the RTK module 5.

[0033] From the above description, it can be seen that in order to facilitate the disassembly and assembly of the RTK module 5, the electromagnet 7 is used to absorb the clamping jaws 3 for clamping. The power supply of the electromagnet 7 can be controlled at any time to control whether the clamping jaws 3 are clamped, thereby facilitating the installation or disassembly of the RTK module 5.

[0034] Furthermore, the top of the clamping jaw 3 extending out of the sliding cavity 10 is integrally connected with a clamping bevel 9, and the free ends of the two opposite clamping bevels 9 are inclined toward each other; a pressure detection plate 8 is fitted and fixed to the top of the clamping bevel 9, and a control panel is arranged inside the mounting bracket 4, and the control panel is electrically connected to the pressure detection plate 8 and the electromagnet 7 respectively. When the pressure detected by the pressure detection plate 8 is greater than the preset pressure value, the control panel controls the electromagnet 7 to lose power.

[0035] During specific use, the RTK module 5 is fitted into the inclined surface of the clamping bevel block 9, the pressure detection plate 8 detects the pressure of the RTK module 5, and transmits the pressure signal to the control panel. The control panel controls the electromagnet 7 to lose power, so that the two clamping jaws 3 can be loosened, and in the process of continuous advancement of the RTK module 5, the clamping bevel block 9 will be pushed away, thereby facilitating the RTK module 5 to be clamped between the two clamping bevel blocks 9. At the same time, the pressure detection plate 8 does not receive any pressure, and the control panel controls the electromagnet 7 to be energized to continue to adsorb the clamping jaws 3 to complete the clamping, so that the RTK module 5 can be installed more conveniently and labor-savingly.

[0036] Furthermore, a switch is provided between the control panel and the pressure detection plate 8. After the RTK module 5 is clamped, the connection between the control panel and the pressure detection plate 8 can be cut off by the switch to prevent the pressure detection plate 8 from being accidentally touched and causing the clamp 3 to be loosened.

[0037] Furthermore, one end of the clamping jaw 3 disposed inside the sliding cavity 10 is arranged in a T-shape to prevent it from slipping out.

[0038] The working principle of the utility model is as follows: the transmitter of the identification instrument body 1 is turned on and connected to the cable to be tested according to the wiring method in the manual, and the transmitter injects a high-frequency AC signal; the identification instrument body 1 and the RTK module 5 are turned on, and the two are automatically paired by Bluetooth, and the RTK module 5 can obtain the current accurate longitude and latitude information in real time and transmit it to the receiver via Bluetooth; the receiver can input the current cable information, and record the longitude and latitude, burial depth and cable information of the cable together; the tester records the current cable information in turn every several tens of meters or at the point where the path direction changes, and when arriving at the cable well, the current cable well location information can be marked at the same time, and the direction of the cable in the cable well, the cable model, etc. can be manually entered, and other cables in the well can be calculated and identified through the RTK module 5;

[0039] Repeat the above steps until you reach the end of the cable, save all the cable information, and then obtain the cable path and cable identification.
