Description

Technical Field

[0001] The present application relates to the field of cable survey technology, and in particular to a cable detector for centimeter-level on-site survey. Background Art

[0002] In modern urban infrastructure construction, accurate detection and location of underground cables is crucial for ensuring power supply, communication networks, and building safety. With the continuous advancement of urbanization and industrialization, underground pipeline networks are becoming increasingly complex, requiring cable detection technology to possess higher precision and reliability. Traditional cable detection technology is no longer able to meet the growing demand, especially in scenarios requiring high-precision (centimeter-level) site surveys.

[0003] Existing cable detectors are typically operated manually by hand, which not only limits detection efficiency, but also requires carrying and using a variety of detection equipment of varying precision, and performing multiple tests to ensure data accuracy when conducting high-precision detection. However, these traditional detectors lack portability and human-friendly design considerations, resulting in operators expending a lot of physical effort during frequent movement and use. This not only wastes time and human resources, but also, when used outdoors or in complex terrain, the probe easily comes into contact with the ground, and careless movement by the operator may cause the probe to collide with rocks or other obstacles on the ground, thereby damaging the detector probe. In addition, when the equipment is subjected to external vibrations and shocks, the internal precision sensors and electronic components may shift or become loose, which will directly affect the accuracy of the measurement.

[0004] In view of the above problems, there is an urgent need to propose a new type of cable detector, which can not only provide centimeter-level high-precision detection capabilities, but also be more humane and portable in design to adapt to the complex and changeable field survey needs, improve work efficiency, and ensure data accuracy and equipment durability.

[0069] The embodiment of the present application discloses a cable detector for centimeter-level on-site surveys.

[0070] See also Figures 1 to 10 An embodiment of a cable detector for centimeter-level field survey provided in the present application includes:

[0071] Detector body 1, mobile frame 2 and mounting mechanism 3.

[0072] A handle 11 is fixed to the top of the detector body 1 .

[0073] The mobile frame 2 is longitudinally U-shaped, located on one side of the detector body 1, and is used to carry the detector body 1; a universal wheel 21 is provided at the bottom of the mobile frame 2; a push handle 22 is fixedly installed on the side of the mobile frame 2 away from the detector body 1; a control panel 23 is fixedly connected to the side wall of the mobile frame 2.

[0074] The mounting mechanism 3 is installed on the side of the mobile frame 2 away from the push handle 22, and includes an electric cylinder 31, a circular frame 32, an adjustment component 33, an electric push rod 34 and multiple fixing components 35; the electric cylinder 31 is fixedly set on the top of the mobile frame 2; the circular frame 32 is fixedly set at the bottom of the electric cylinder 31; the adjustment component 33 is set at the bottom of the circular frame 32; there are multiple electric push rods, which are distributed in a circular array at the bottom of the adjustment component 33; multiple fixing components 35 are set at the bottom of the electric push rod 34 for fixing multiple detector bodies 1 one by one.

[0075] In the above design, in order to use multiple detector bodies 1 at the same time to improve the detection accuracy, multiple detector bodies 1 can be installed on the mobile frame 2 through the installation mechanism 3. After the installation is completed, the push handle 22 and the universal wheel 21 are used to move the entire mobile frame 2 to the location where detection is required. During the specific operation, the electric cylinder 31 is started to drive the bottom ring frame 32 to move downward. When installing the detector body 1, as shown in FIG. Figure 2 As shown, the detector body 1 can be first fixed to the bottom of the circular frame 32 by the fixing component 35, and then the position of the detector body 1 can be fine-tuned using the adjustment component 33, so as to facilitate multiple detections of the same location and ensure the accuracy and reliability of the detection results. This design not only improves the detection efficiency, but also enhances the flexibility and adaptability of the device.

[0076] Furthermore, the control panel 23 allows the operator to conveniently control the operation of the electric cylinder 31 and electric push rod 34, enabling rapid installation and removal of the detector body 1 and precise position adjustment. The control panel 23 can be equipped with a display and buttons. The display displays the current operating status and parameter settings, while the buttons execute various operating commands, such as start, stop, raise, lower, and fine-tune, thereby greatly improving the convenience and intuitiveness of operation.

[0077] The above is an embodiment of the present invention that provides a cable detector for centimeter-level on-site survey. The following is an embodiment of the present invention that provides a cable detector for centimeter-level on-site survey. For details, please refer to Figures 1 to 10 .

[0078] Based on the solution of the above embodiment 1:

[0079] Furthermore, if Figure 4 As shown, the adjustment assembly 33 includes a rotating disk 331 , a driving block 335 and a motor 337 .

[0080] A plurality of circular grooves 332 arranged in a circular array are provided on the top of the rotating disk 331; a driving disk 333 is clamped inside the circular groove 332; a connecting column 334 is fixedly provided on the top of the driving disk 333; a driving block 335 is fixedly mounted on the connecting column 334 and is rotatably connected to the bottom of the circular frame 32; a motor 337 is fixedly provided on the circular frame 32 to drive the driving block 335 to rotate.

[0081] A plurality of fixed disks 336 arranged in a circular array are fixedly provided at the bottom of the rotating disk 331 ; a plurality of protrusions 3361 in contact with the driving block 335 are fixedly provided at the top of the fixed disk 336 ; and the bottom of the fixed disk 336 is fixedly connected to the electric push rod 34 .

[0082] The tops of the plurality of protrusions 3361 are fixedly connected to the limiting pillars 3362 ; a circular groove 321 is formed at the bottom of the circular frame 32 ; the protrusions 3361 slide in the circular groove 321 .

[0083] In the above design, after the detector body 1 is fixed by using the fixing component 35, in order to realize multiple detections of the same position by multiple detector bodies 1 at the same time, the motor 337 can be used to drive the connecting column 334 to rotate so that the driving disk 333 and the driving block 335 fixed thereto can rotate synchronously. The driving block 335 will hit the protrusion 3361 closest to the connecting column during the rotation. When the driving block 335 contacts the nearest protrusion 3361 and continues to rotate, it will infer the rotation of the protrusion 3361, thereby driving the fixed disk 336 to rotate, so that the rotating disk 331 rotates synchronously. As the driving block 335 moves with the currently pushed protrusion 3361, when the protrusion 3361 leaves the motion trajectory range of the driving block 335, the driving The moving block 335 no longer drives the protrusion 3361 to move, and the protrusion 3361 is deemed to have completed the striking drive; in the present application, one circular groove corresponds to one protrusion 3361, and when the protrusion 3361 is driven, the driving disk 333 also rotates synchronously, thereby causing a transfer in the corresponding circular groove 332. Taking the four protrusions 3361 / four circular grooves 332 in the figure as an example, each time a protrusion 3361 is struck, the protrusion 3361 switches to the position of the next protrusion 3361, that is, the driving disk rotates 1 / 4, thereby driving the fixed disk 336 to achieve intermittent rotation, thereby causing the electric push rod 34 at the bottom and the fixed detector body 1 to rotate intermittently, so that each detector body 1 can detect the same location, thereby achieving multiple detections of the same location.

[0084] In addition, in order to achieve stable impact of the driving block 335 on the protrusion 3361 during the rotation process, a limiting column 3362 is fixedly connected to the top of the protrusion 3361, and a circular groove 321 is provided at the bottom of the circular frame 32, and the protrusion 3361 slides in the circular groove 321. This design can not only limit the rotation trajectory of the protrusion 3361 and improve the stability of the rotation of the protrusion 3361, but also ensure that the driving block 335 is always in contact with the protrusion 3361 during the rotation process, thereby achieving stable impact on the protrusion 3361 and ensuring the stable operation of the entire adjustment component 33.

[0085] Furthermore, if Figures 5 to 10 As shown, each fixing assembly 35 includes a mounting box 351;

[0086] Each mounting box 351 is fixedly arranged at the bottom of the plurality of electric push rods 34 in a one-to-one correspondence.

[0087] The mounting box 351 is provided with a mounting slot 3511 ; a mounting plate 352 is slidably engaged inside the mounting box 351 ; the mounting plate 352 is a hollow plate, and an abutting component 353 is provided inside.

[0088] The detector body 1 is located at the bottom of the mounting box 351 ; the handle 11 is snap-fitted to the mounting plate 352 . The handle 11 is in an inverted U-shape and is hooked onto the mounting plate 352 .

[0089] The mounting plate 352 is in the shape of an I-character, and its two ends are in sliding contact with the mounting slot 3511; a slot 3521 is provided at the top center of the mounting plate 352; movable slots 3522 are provided on both symmetrical sides of the mounting plate 352; and slots 3523 are provided on both symmetrical ends of the mounting plate 352 located outside the mounting box 351.

[0090] The abutment component 353 includes a moving block 3531 slidably arranged inside the two moving grooves 3522 and two tension springs 3535; the abutment block 3532 is slidably clamped inside the groove 3521; a telescopic spring 3533 is fixedly arranged at the bottom of the abutment block 3532; a ejection block 3534 is fixedly arranged at the bottom of the telescopic spring 3533; the two tension springs 3535 are fixedly arranged on both sides symmetrically of the bottom of the abutment block 3532 and are fixedly connected to the side close to the moving block 3531.

[0091] The ejection block 3534 is trapezoidal in shape and gradually becomes smaller from top to bottom; abutment rods 35311 are fixedly provided on the sides of the moving blocks 3531 that are close to each other; the abutment rods 35311 abut against the inclined side of the ejection block 3534; and the sides of the two moving blocks 3531 that are away from each other abut against the inner wall of the handle 11 respectively.

[0092] The top of the slot 3523 is slidably plugged with a limiting sleeve 354; the bottom of the limiting sleeve 354 is symmetrically fixed on both sides with plug-in plates 3541 that slide and engage with the slot 3523. The limiting sleeve 354 is rectangular and slides onto the outside of the installation box 351.

[0093] When the cam 352 is in the unlock position, the cam 3531 is in the unlock position, and the cam 3532 is locked in the unlock position, so that the cam 3532 is locked. The cam 3531 is then released from the cam 3521 and the cam 3532 is released, and the cam 3533 is released to the cam 3522.

[0094] To enhance the stability of the detector body 1 within the mounting box 351, limit slots can be provided on both sides of the inner wall of the mounting slot 3511, and limit sliders can be symmetrically fixed at both ends of the mounting plate 352. Thus, when the mounting plate 352 slides within the mounting slot 3511, the limit sliders can slide synchronously within the limit slots, effectively preventing the mounting plate 352 from shifting or shaking during installation, further enhancing the stability and reliability of the entire fixing assembly 35.

[0095] In addition, to facilitate the operator's quick identification of the fixed state of the mounting plate 352, a status indicator light may be provided on the top of the limiting sleeve 354. When the inserting plate 3541 of the limiting sleeve 354 is successfully slid and engaged in the slot 3523, the status indicator light illuminates, indicating that the mounting plate 352 is fixed. When the limiting sleeve 354 is removed and the inserting plate 3541 is separated from the slot 3523, the status indicator light goes out, indicating that the mounting plate 352 is not fixed.

[0096] Working principle and usage process of this application:

[0097] When using the device, first manually place the detector body 1 into the installation box 351, then insert the installation plate 352 into the installation groove 3511 so that it is located at the bottom of the handle 11, and fix the installation plate 352 through the limit sleeve 354 to ensure its stability. After the fixation is completed, release the handle 11 and let it fall naturally under the action of gravity, and fix the two sides of the handle 11 through the abutment component 353 to ensure the stable installation of the detector body 1. After the installation is completed, manually push the mobile frame 2 to move the entire device to the location where detection is required. After arriving at the detection location, start The electric cylinder 31 drives the circular frame 32 to move downward, causing the detector body 1 fixed at the bottom to move downward synchronously to start detecting the cable. According to the unevenness of the ground, the electric push rod 34 can be used again to fine-tune the height of multiple detector bodies 1 to avoid the detector body 1 from scratching the ground in places with higher terrain. During the detection process, the adjustment component 33 is used to drive the multiple detector bodies 1 at the bottom to rotate intermittently, thereby realizing multiple detections and improving the accuracy of the detection. This design not only enhances the flexibility of detection, but also ensures the accuracy of the detection results.

[0098] To further enhance the practicality and convenience of the entire device, a cushion can be installed at the bottom of the mounting box 351. This cushion can be made of a highly elastic and wear-resistant material, such as rubber or silicone. When the detector body 1 is secured within the mounting box 351, the cushion effectively absorbs and disperses vibrations and impacts from the ground, thereby protecting the detector body 1 from damage and extending its service life.

[0099] Furthermore, to facilitate the operator's use of the device in dimly lit or nighttime environments, a lighting device may be provided on the mobile frame 2. This lighting device may be an LED light strip or LED bulb, etc., with adjustable brightness, allowing for flexible adjustment based on actual needs. When detection is required at night or in dimly lit environments, the operator can turn on the lighting device to provide sufficient illumination for the entire device, ensuring smooth detection.

[0100] In summary, this application provides a centimeter-level cable detector for field surveys. By adopting the above-mentioned structural design and technical solutions, it not only enables the rapid installation, removal, and fixation of multiple detector bodies, but also improves the accuracy and efficiency of detection. Furthermore, the device has the advantages of simple structure, convenient operation, and strong practicality, making it suitable for cable detection in various complex environments.
