Description

Technical Field

[0001] The present application relates to the technical field of cable detection, and in particular to a cable detection device based on PTK multi-signal assisted positioning. Background Art

[0002] With the acceleration of urbanization and the continuous improvement of power infrastructure, cable installation and maintenance, as a crucial means of power transmission and distribution, are receiving increasing attention. Traditional cable detection methods rely primarily on manual experience and simple detection equipment, which is not only inefficient but also prone to errors. To overcome these limitations, cable detectors based on PTK (Precision Terrain Knowledge) multi-signal assisted positioning have been introduced. PTK multi-signal assisted positioning technology combines satellite navigation, inertial navigation, and ground feature recognition to achieve high-precision, real-time, and continuous positioning of cables. This technology not only improves the accuracy and efficiency of cable detection, but also significantly reduces reliance on manual intervention, providing strong technical support for cable installation, maintenance, and troubleshooting.

[0003] However, in actual applications, workers usually need to hold the cable detector for a long time to perform measurements, which puts a heavy physical burden on them. At the same time, long-term handheld operation has low work efficiency and may introduce additional errors due to unstable hand-held posture, reducing the accuracy of the detection results.

[0004] Furthermore, the probe at the bottom of the cable detector is susceptible to static electricity and other factors, which can easily accumulate dust and form a dust layer. Because the probe is close to the ground, it easily comes into contact with the ground during measurement and accumulates dust. Long-term dust accumulation can absorb or reflect part of the signal, weakening the signal reaching the probe, thereby affecting the detector's sensitivity and accuracy. It can also cause physical damage to the probe, such as wear and corrosion, shortening its lifespan and increasing repair and replacement costs. Furthermore, if the dust contains metal particles or other conductive substances, they can interfere with the transmission and reception of electromagnetic signals, further exacerbating errors in detection results.

For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0077] Please refer to Figures 1 to 8In an embodiment of the present application, a PTK multi-signal assisted positioning cable detection device is provided, comprising: a vehicle frame 1, a soot blowing mechanism, and a detector 14; the detector 14 is disposed on the vehicle frame 1; a rotatable active rod 8 is disposed on the vehicle frame 1; a first wheel 9 is disposed on the active rod 8; the soot blowing mechanism comprises: a fixed block 10, a connecting rod 1003, a piston 1101, and a hollow cylinder 12; the hollow cylinder 12 is fixed to the vehicle frame 1; a cavity is disposed in the hollow cylinder 12, and a spray hole 12011 communicating with the cavity is disposed on the surface of the hollow cylinder 12; the spray hole 12011 faces the bottom of the detector 14; The piston 1101 can be slidably arranged in the hollow cylinder 12, and the piston 1101 is used to compress the cavity; the fixed block 10 is fixed to the frame 1, and a rotatable driven rod 1001 is provided on the fixed block 10; the driven rod 1001 is transmission-connected to the active rod 8, and a disc 1002 is provided at the end of the driven rod 1001; the length direction of the connecting rod 1003 is arranged parallel to the radial direction of the disc 1002; one end of the connecting rod 1003 is rotatably arranged on the end face of the disc 1002, and is eccentrically arranged with the disc 1002; the other end of the connecting rod 1003 is connected to the piston 1101.

[0078] In this embodiment, the frame 1 may be provided with a handlebar for use by a user and for moving the frame 1; specifically, the handlebar may be provided on the upright column 2 described below. The first wheel 9 may serve as a support wheel for the frame 1. As the frame 1 moves along the road, the first wheel 9 rolls to drive the frame 1 forward.

[0079] In this embodiment, the piston 1101 can be connected to the other end of the connecting rod 1003 via the push rod 11. The direction in which the piston 1101 slides along the hollow cylinder 12 is parallel to the radial direction of the first wheel 9. When the first wheel 9 rotates, it can drive the connecting rod 1003 and the push rod 11 to reciprocate, thereby driving the piston 1101 to reciprocate within the hollow cylinder 12, thereby driving the spray hole 12011 to spray air. Because the spray hole 12011 is facing the bottom of the detector 14, the airflow ejected from the spray hole 12011 can effectively remove dust adsorbed on the bottom of the detector 14 due to static electricity and other reasons, ensuring that the detection accuracy of the detector 14 is not affected and preventing dust from affecting signal transmission and causing physical damage to the probe of the detector 14.

[0080] As an embodiment, an avoidance groove 102 is provided on the vehicle frame 1; the disc 1002 is disposed in the avoidance groove 102 to reduce friction and wear of the disc 1002 and improve the durability of the device.

[0081] In one embodiment, the hollow cylinder 12 includes two; the two hollow cylinders 12 are arranged at intervals along the axial direction of the driven rod 1001; a disc 1002 is provided at both ends of the driven rod 1001; the soot blowing mechanism includes two connecting rods 1003 and two pistons 1101; the two pistons 1101 are respectively arranged in the two hollow cylinders 12; the two connecting rods 1003 are respectively connected to the two pistons and the two discs 1002.

[0082] Specifically, a driving gear 802 can be fixedly mounted on the active rod 8, and a driven gear 13 can be mounted on the driven rod 1001. The driving gear 802 and the driven gear 13 are meshed and connected to achieve a transmission connection between the active rod 8 and the driven rod 1001. A gear slot 101 is provided on the vehicle frame 1, and the driven gear 13 partially enters the gear slot 101 without contacting the slot wall of the gear slot 101.

[0083] By providing discs 1002 at both ends of the driven rod 1001, the driven rod 1001 can simultaneously drive the two pistons 1101 to compress the cavities in the two hollow cylinders 12 respectively when rotating, thereby increasing the air flow injection force and more effectively removing dust from the bottom of the detector.

[0084] Furthermore, the two hollow cylinders 12 are integrally connected at one end away from the driven rod 1001 , and the cavities in the two hollow cylinders 12 are interconnected; the spray hole 12011 is provided at the end of the hollow cylinder 12 away from the driven rod 1001 .

[0085] In practice, the end of the hollow cylinder 12 away from the driven rod 1001 can be provided with an expansion section 1201, giving the hollow cylinder 12 a T-shaped structure. The expansion sections 1201 of the two hollow cylinders 12 are integrated. Spray holes 12011 are provided at the end of the expansion section 1201 away from the driven rod 1001. Multiple spray holes 12011 can be spaced horizontally to increase the dust removal area and improve dust removal uniformity.

[0086] In one embodiment, a support rod 801 is provided on the vehicle frame 1; a second wheel 901 is provided on the support rod 801; the first wheel 9 and the second wheel 901 are spaced apart; and the detector 14 is located between the first wheel 9 and the second wheel 901 in the horizontal direction.

[0087] In one embodiment, a column 2 and an adjustment mechanism are provided on the frame 1; a rotatable screw rod 3 is provided in the column 2, and the screw rod 3 is vertically arranged; the adjustment mechanism includes: a mounting block 4; the mounting block 4 can be slidably arranged on the column 2, and the mounting block 4 is engaged with the screw rod 3; the detector 14 is connected to the mounting block 4, that is, the detector 14 is arranged on the frame 1 through the mounting block 4 and the column 2.

[0088] The mounting block 4 can move up and down along the column 2; by adjusting the rotation of the screw rod 3, the height of the detector 14 can be adjusted to ensure accurate detection at different positions.

[0089] In one embodiment, the mounting block 4 may be T-shaped. A mounting slot 201 is provided in the column 2; the screw rod 3 is provided in the mounting slot 201, and the top end of the screw rod 3 extends out of the column 2, which is convenient for manual adjustment by the staff.

[0090] In one embodiment, two clamping blocks 7 are provided on the mounting block 4, which can be opened and closed horizontally. The detector 14 is clamped on the two clamping blocks 7 to connect the detector 14 to the mounting block 4. The clamping blocks 7 can hold and lift the detector 14. Furthermore, the two clamping blocks 7 can be adapted to the size of the detector 14.

[0091] Further, see Figure 3 and Figure 4 A rotatable rotating rod 5 is provided in the mounting block 4; two arc-shaped grooves 5021 are provided at the end of the rotating rod 5; cylinders 701 are fixedly installed on one end of the two clamping blocks 7 close to the mounting block 4, and the two cylinders 701 are respectively corresponding to the two arc-shaped grooves 5021 for sliding connection.

[0092] When the rotating rod 5 rotates, the cylinder 701 slides within the arcuate groove 5021. Therefore, the rotating arcuate groove 5021 can drive the cylinder 701 to move horizontally, thereby driving the two clamping blocks 7 to open and close. It should be noted that the end of the mounting block 4 away from the screw rod 3 can be provided with a horizontal groove; the clamping block 7 can be slidably disposed in the horizontal groove, thereby providing a guide for the clamping block 7.

[0093] As an embodiment, a slot 401 is provided inside the mounting block 4 ; the rotating rod 5 is installed in the slot 401 ; and the adjusting rod 6 used for adjustment described below partially penetrates into the slot 401 .

[0094] In one embodiment, a rotatable adjusting rod 6 is provided on the mounting block 4 ; the top end of the adjusting rod 6 extends out of the mounting block 4 ; and the bottom end of the adjusting rod 6 is transmission-connected to the rotating rod 5 .

[0095] Specifically, a first bevel gear 501 is provided on the rotating rod 5 ; a second bevel gear 601 is provided on the adjusting rod 6 , and the two are meshed and connected so that the rotation of the adjusting rod 6 can drive the rotating rod 5 to rotate, thereby controlling the opening and closing of the clamping block 7 .

[0096] Furthermore, the clamping block 7 is provided with an inclined groove 702 that is tilted relative to the vertical direction; the detector 14 is inserted into the inclined groove 702 so that the detector 14 is more firmly clamped by the clamping block 7 .

[0097] Furthermore, an upwardly protruding top block 703 is provided on the top of one end of the clamping block 7 away from the mounting block 4 .

[0098] The design of the inclined slot 702 can further increase the stability of the clamping and prevent the detector 14 from slipping or shaking during movement. At the same time, the top block 703 can support the display part of the detector to prevent it from being damaged and keep it stable.

[0099] The use process of the PTK multi-signal assisted positioning cable detection device provided in the present application can be: first, adjust the rod 6, drive the second bevel gear 601 to rotate through the adjusting rod 6, drive the first bevel gear 501 and the rotating rod 5 to rotate through the engagement of the second bevel gear 601 with the first bevel gear 501, and drive the round block 502 on the rotating rod 5 to rotate through the rotating rod 5; because the two arc grooves 5021 provided on the round block 502 are designed in a semicircular arc shape and are designed to spread outward with the axis of the rotating rod 5 as the center of the circle, when the round block 502 rotates, the two cylinders 701 and the clamping block 7 that are slidably connected to the two round blocks 502 perform horizontal movement closer to or away from each other inside the mounting block 4. After the clamping block 7 is opened and closed to the appropriate distance, the staff can put the detector 14 in the middle of the two clamping blocks 7, and rotate the adjusting rod 6 again so that the two clamping blocks 7 are close to each other to clamp the detector 14. When the detector 14 is clamped and locked, the bottom outer wall of the detector 14 is inserted into the two inclined grooves 702 , and the two top blocks 703 are fixed below the display of the detector 14 .

[0100] After the detector 14 is clamped and fixed, the height of the detector 14 can be adjusted according to the detection distance of the detector 14 so that the probe at the bottom of the detector 14 maintains an appropriate distance from the ground; the height of the detector 14 is adjusted by rotating the screw rod 3, which is threadedly connected to the mounting block 4, thereby driving the mounting block 4 to adjust the height in the vertical direction along the axis of the screw rod 3.

[0101] After the height of the detector 14 has been adjusted, the staff pushes the column 2 to drive the frame 1 to move. With the pushing force applied by the staff, the first wheel 9 and the second wheel 901 rotate and respectively drive the corresponding active rod 8 and support rod 801 to rotate;

[0102] The active rod 8 drives the active gear 802 to rotate, and the engagement of the toothed active gear 802 with the driven gear 13 drives the driven gear 13 and the driven rod 1001 to rotate; the driven rod 1001 drives the two discs 1002 to rotate, and the connecting rod 1003 is connected to the disc 1002 in rotation, so that the rotational motion of the two discs 1002 is converted into reciprocating motion of the two push rods 11 in the horizontal direction, thereby driving the two pistons 1101 to reciprocate in the corresponding hollow cylinder 12; when the piston 1101 moves toward the expansion section 1201, it squeezes the air inside the expansion section 1201, so that the air is ejected through the nozzle 12011, thereby blowing away the dust at the bottom probe of the detector 14, and avoiding the formation of a dust layer on the detector 14.

[0103] The above are only preferred embodiments of the present application and are not intended to limit the present invention. Although the present application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the aforementioned examples or make equivalent replacements for some of the technical features therein. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
