Description

Technical Field

[0001] This utility model relates to a fault inspection device, specifically a power grid fault inspection device. Background Technology

[0002] Power grid fault inspection is a crucial link in ensuring the safe and stable operation of the power system. It mainly involves regular or targeted inspections of transmission, substation, and distribution equipment and lines to promptly identify potential hazards, locate faults, and promote repairs. Since transmission, substation, and distribution equipment are often located in relatively flat environments, inspection vehicles are frequently used for inspections. However, power lines are often erected outdoors in relatively complex environments (making inspection vehicles less suitable for their work), making fault inspections of power lines more challenging.

[0003] Common line inspection methods include manual inspection, fixed inspection devices, and mobile inspection devices. Manual inspection, as the name suggests, involves manually checking along the line, which is time-consuming and inefficient. Fixed inspection devices mainly consist of probes fixedly installed on power poles, which detect cables in real time to achieve the inspection purpose. However, since the distance between power poles is relatively large, the accuracy requirements of the probes are high, increasing the inspection cost. Mobile inspection devices consist of a frame that slides on the cable. Probes are fixedly installed on the frame, and the frame moves to move the probes for line inspection. Since the relative distance between the probe and the cable is short, the accuracy requirements of the probe are not high.

[0004] Since the probes of common mobile inspection devices are fixedly mounted on the frame, the probes can only inspect one side of the cable as the frame moves. This makes it easy to miss some faults during the inspection process (the fault point is located on the back side of the probe's inspection), thus affecting the normal use of the cable. Although adding probes can solve the problem of missed faults, it will greatly increase the cost and weight of the device. Utility Model Content

[0005] The purpose of this invention is to provide a power grid fault inspection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A power grid fault inspection device includes a lower frame and an upper frame; the lower frame and the upper frame are fixedly connected by bolts and are wrapped with cables; an inspection probe for detecting faults is provided on the lower frame.

[0008] The traveling component includes a drive roller rotatably mounted on the lower frame; the drive roller engages with the cable in a rolling manner.

[0009] The rotating component, when the moving component moves the inspection probe along the length of the cable, can cause the inspection probe to rotate along the axis of the cable.

[0010] The power grid fault inspection device described above has the following features: multiple sets of sliding grooves symmetrically arranged on the upper frame; a slider is slidably installed in the sliding groove; a spring is provided on the slider; the two ends of the spring respectively abut against the slider and the upper frame; an abutting roller is rotatably installed on the slider; and the abutting roller cooperates with the driving roller.

[0011] The power grid fault inspection device described above includes: the traveling component further includes a motor mounted on the lower frame; a rotating shaft is mounted on the output end of the motor, and a first bevel gear is mounted on the rotating shaft; a second gear is mounted on the drive roller; a second bevel gear meshing with the first bevel gear is rotatably mounted on the lower frame; and a first gear meshing with the second gear is mounted on the second bevel gear.

[0012] The power grid fault inspection device described above includes: a rotating component comprising a fixed sleeve mounted on the lower frame; the fixed sleeve being sleeved with the cable; a rotating sleeve rotatably mounted on the fixed sleeve; a turntable mounted on the rotating sleeve; the turntable being fixedly connected to the inspection probe; a large gear mounted on the rotating sleeve; and a small gear meshing with the large gear mounted on the rotating shaft.

[0013] The power grid fault inspection device described above has multiple sets of counterweight rings installed at the bottom of the lower frame, and the multiple sets of counterweight rings are symmetrically arranged.

[0014] The power grid fault inspection device described above has a handle installed on its upper frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are: through the cooperation of the walking component and the rotating component, the inspection probe can perform fault inspection along the spiral trajectory. During the inspection, the detection angle is relatively wide, which can avoid the phenomenon of missed detection. Moreover, since the inspection probe performs the detection action during the movement, the relative distance between the inspection probe and the cable is short, so the detection accuracy requirement of the inspection probe is low, which can reduce the production cost of the device.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0035] Please see Figures 1-6 As an embodiment of this utility model, the power grid fault inspection device includes a lower frame 1 and an upper frame 2; the lower frame 1 and the upper frame 2 are fixedly connected by bolts and are wrapped with cables 12; an inspection probe 11 for detecting faults is provided on the lower frame 1.

[0036] The traveling component includes a drive roller 6 rotatably mounted on the lower frame 1; the drive roller 6 is in rolling engagement with the cable 12.

[0037] The rotating component, when the movement of the walking component causes the inspection probe 11 to move along the length direction of the cable 12, can cause the inspection probe 11 to rotate along the axis of the cable 12.

[0038] In this embodiment, the drive roller 6 is brought into contact with the lower part of the cable 12, and then the upper frame 2 and the lower frame 1 are fixedly connected by bolts; after connection, the cable 12 is located between the upper frame 2 and the lower frame 1 and is in contact with the drive roller 6.

[0039] Fault inspection: The start device drives the walking and rotating parts to move synchronously. When the walking part moves, the drive roller 6 will rotate, thus rolling and cooperating with the cable 12. Through the friction between the drive roller 6 and the cable 12, the drive roller 6 can be driven to move along the length of the cable 12. This drives the inspection probe 11 to move synchronously through the upper frame 2 and the lower frame 1 to perform the fault inspection action. When the rotating part moves, it will drive the inspection probe 11 to rotate along the axis of the cable 12.

[0040] By cooperating with the moving and rotating parts, the inspection probe 11 can perform fault inspection along a spiral trajectory. During the inspection, the detection angle is relatively wide, which can avoid missed detection. Since the inspection probe 11 performs the detection action during the movement, the relative distance between the inspection probe 11 and the cable 12 is short. Therefore, the detection accuracy requirement of the inspection probe 11 is low, which can reduce the production cost of the device.

[0041] As a further embodiment of this utility model, multiple sets of sliding grooves 201 are symmetrically provided on the upper frame 2. A slider 7 is slidably installed in the sliding groove 201. A spring 8 is provided on the slider 7. The two ends of the spring 8 respectively abut against the slider 7 and the upper frame 2. An abutting roller 9 is rotatably installed on the slider 7. The abutting roller 9 cooperates with the driving roller 6.

[0042] In this embodiment, after the drive roller 6 comes into contact with the cable 12, the upper frame 2 and the lower frame 1 are connected by bolts. During the connection process, the contact roller 9 will come into contact with the upper part of the cable 12. As the distance between the upper frame 2 and the lower frame 1 becomes shorter (connection stability increases), the cable 12 will squeeze the contact roller 9, thereby driving the slider 7 to move away from the lower frame 1 in the slide groove 201 through the contact roller 9, and compressing the spring 8. The elastic force of the spring 8 can make the contact roller 9 and the cable 12 more tightly, thereby increasing the squeezing force of the cable 12 on the drive roller 6, so as to improve the reliability of the contact between the drive roller 6 and the cable 12, avoid slippage, and thus improve the stability of the inspection.

[0043] As a further embodiment of this utility model, the walking component also includes a motor 3 mounted on the lower frame 1; a rotating shaft 4 is mounted on the output end of the motor 3, and a first bevel gear 401 is mounted on the rotating shaft 4; a second gear 601 is mounted on the drive roller 6; a second bevel gear 5 that meshes with the first bevel gear 401 is rotatably mounted on the lower frame 1; and a first gear 501 that meshes with the second gear 601 is mounted on the second bevel gear 5.

[0044] In this embodiment, the inspection process is as follows: the motor 3 is started, which drives the rotating shaft 4 to rotate, thereby driving the first bevel gear 401 to rotate; through the meshing of the first bevel gear 401 and the second bevel gear 5, the second bevel gear 5 is driven to rotate, thereby driving the first gear 501 to rotate; through the meshing of the first gear 501 and the second gear 601, the drive roller 6 is driven to rotate, thereby causing the drive roller 6 to roll on the cable 12, and through the friction between the drive roller 6 and the cable 12, the inspection probe 11 can be moved along the length of the cable 12 through the upper frame 2 and the lower frame 1. During the movement, the inspection probe 11 will perform fault inspection on the cable 12.

[0045] Since the inspection probe 11 performs the detection action while moving, the relative distance between the inspection probe 11 and the cable 12 is relatively short. Therefore, the detection accuracy requirement of the inspection probe 11 is low, which can reduce the production cost of the device.

[0046] As a further embodiment of this utility model, the rotating component includes a fixed sleeve 101 mounted on the lower frame 1; the fixed sleeve 101 is sleeved with the cable 12; a rotating sleeve 10 is rotatably mounted on the fixed sleeve 101; a turntable 1001 is mounted on the rotating sleeve 10; the turntable 1001 is fixedly connected to the inspection probe 11; a large gear 1002 is mounted on the rotating sleeve 10; and a small gear 402 that meshes with the large gear 1002 is mounted on the rotating shaft 4.

[0047] In this embodiment, when the walking component moves, the rotating shaft 4 will rotate, thereby driving the small gear 402 to rotate. Through the meshing of the small gear 402 and the large gear 1002, the large gear 1002 will rotate, thereby driving the rotating sleeve 10 to rotate on the fixed sleeve 101. This will cause the inspection probe 11 to rotate along the axis of the fixed sleeve 101 (the axis of the cable 12) through the turntable 1001.

[0048] That is, while the inspection probe 11 moves along the length of the cable 12 under the drive of the traveling component, it will also rotate along the axis of the cable 12 under the drive of the rotating component; the movement trajectory of the inspection probe 11 during the entire inspection process is spiral.

[0049] By cooperating with the moving and rotating parts, the inspection probe 11 can perform fault inspection along a spiral trajectory. During the inspection, the detection angle is relatively wide, which can avoid missed detection.

[0050] As a further embodiment of this utility model, multiple sets of counterweight rings 102 are installed at the bottom of the lower frame 1; and the multiple sets of counterweight rings 102 are symmetrically arranged.

[0051] In this embodiment, by suspending heavy objects (such as sandbags or counterweights) on the counterweight ring 102, the overall weight of the device is increased, and the overall center of gravity of the device is lowered (the center of gravity is always located below the cable 12), which can prevent the device from swaying during the inspection process and causing missed inspections.

[0052] As a further improvement of this utility model, a handle 202 is installed on the upper frame 2.

[0053] In this embodiment, the handle 202 can reduce the difficulty of connecting the upper frame 2 and the lower frame 1 and improve the convenience of device installation.

[0054] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
