Description

Technical Field

[0001] The invention relates to the technical field of wire quality inspection devices, in particular to a wire quality inspection device capable of autonomously raising and lowering wires. Background Art

[0002] Overhead wires are an important carrier of power transmission. Inspecting them can promptly detect problems such as damage and broken strands in the wires, prevent power transmission interruptions due to wire failures, ensure the stable operation of the power system, and provide users with a continuous and reliable power supply.

[0003] The wire quality inspection device is an electrical device that is mounted on the wire and can move along the wire to inspect the wire. It usually includes components such as a traveling mechanism, an inspection box (loading box), and an inspection instrument. At present, there are usually two types of wire quality inspection devices for four-split wires. One is to mount the running wheels of the running mechanism on the two upper wires with the help of an aircraft or an insulating rod, which is convenient for the device to move the wires up and down; the other is that the electrician climbs up the tower to mount the running wheels of the device on the wire, and adds protective measures to the running wheels to prevent the device from falling.

[0004] The shortcomings of the existing technology are: the former has poor stability when encountering crosswinds during the inspection process, and there is a certain probability of falling risk; the latter requires electricians to climb towers to perform high-altitude live work, which is inconvenient to operate and poses a major safety hazard.

[0012] Furthermore, the locking mechanism includes: a sliding pin, which is slidably connected to the fixed block, and one end of the sliding pin has an inclined guide surface; a second elastic member, the process of restoring its deformation drives the sliding pin to slide to the mouth of the blocking slot; a guide member, which is vertically slidably connected to a fixed rod fixedly connected to the fixed block, and the guide member has a guide groove, and the guide groove includes connected vertical grooves and inclined grooves from bottom to top; a sliding column, which is slidably connected in the guide groove; a pull rope, one end of which is fixedly connected to the sliding pin, and the other end is fixedly connected to the sliding column; a second hook, which is fixedly connected to the guide member through a support rod, and the second hook is located inside the first hook; the locking mechanisms of the two mounting units share the same guide member, sliding column and second hook.

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] See also Figure 1-Figure 8 An embodiment of the present invention provides an autonomous upper and lower conductor quality inspection device, comprising an inspection box 1, an inspection component 2 and two parallel mounted units 3. The inspection component 2 comprises a plurality of cameras, an infrared thermal imager and / or an ultrasonic flaw detector. The inspection component 2 adopts the existing technology and will not be described in detail here.

[0031] See also Figure 3 Each mounting unit 3 includes a fixed bracket 31, a movable bracket 32 ​​and a walking assembly. The fixed bracket 31 is fixedly connected to the inspection box 1, one end of the movable bracket 32 ​​is rotatably connected to the fixed bracket 31 or the inspection box 1, and the walking assembly includes an axle 35 and two walking wheels 36. One end of the axle 35 is vertically slidably connected to the fixed bracket 31 through a sleeve, and the other end is fixedly connected to a fixed block 34. A card slot is provided on the fixed block 34. Specifically, the sleeve is fixedly connected to the axle 35, and the sleeve is only slidably connected to the fixed bracket 31 and cannot rotate relative to the fixed bracket 31. It is best that there is a certain sliding damping between the sleeve and the fixed bracket 31. The two walking wheels 36 are coaxially rotatably connected to the axle 35. The walking assembly and the fixed block 34 can slide up and down relative to the fixed bracket 31 as a whole, and the fixed bracket 31 can be driven by the transmission assembly to rotate relative to the fixed bracket 31 until it is engaged with the card slot during the sliding of the fixed bracket 31 relative to the walking assembly.

[0032] As a preferred solution, the transmission assembly includes a first swing rod 38 and a second swing rod 39, one end of the first swing rod 38 is rotatably connected to the wheel shaft 35, and the other end is rotatably connected to one end of the second swing rod 39, and the bottom of the fixed bracket 31 is rotatably connected with a shaft rod 33, one end of the shaft rod 33 is fixedly connected to the movable bracket 32, and the other end is fixedly connected to the second swing rod 39, that is, the end of the second swing rod 39 away from the first swing rod 38 is fixedly connected to the movable bracket 32 ​​through the shaft rod 33. When the walking assembly moves relative to the fixed bracket 31, the movable bracket 32 ​​can be driven to rotate through the first swing rod 38 and the second swing rod 39.

[0033] A first elastic member 37 is also provided between the wheel axle 35 and the fixed bracket 31. The first elastic member 37 stores energy when the walking component slides up relative to the fixed bracket 31, and releases the elastic force of the first elastic member 37 when the walking component slides down relative to the fixed bracket 31. That is to say, the process of the first elastic member 37 recovering the deformation drives the walking component to move downward relative to the fixed bracket 31. Specifically, the first elastic member 37 is preferably a first compression spring sleeved on the fixed bracket 31, and the lower end of the first compression spring abuts against the wheel axle 35 or the sleeve, and the upper end abuts against the top of the fixed bracket 31 or the connecting rod 5.

[0034] A connecting rod 5 is fixedly connected between the tops of the fixing brackets 31 of the two mounting units 3, and a first hook 6 is provided on the connecting rod 5. The first hook 6 is located just above the center of gravity of the entire device. At least one of the running wheels 36 of the two mounting units 3 is a driving wheel, and the driving wheel can be driven by a built-in hub motor.

[0035] In the above technical solution, refer to Figure 7 , the first hook 6 is hooked by a drone or other tool to lift the entire device to float near the four-split wire, so that the walking assembly is slightly higher than the four-split wire, and then the drone is translated close to the wire, so that the two wheels of the walking assembly are respectively located directly above the upper two wires of the four-split wire, and the four-split wire is between the walking assembly and the inspection box 1, and then the drone descends so that the two walking wheels 36 of the walking assembly are mounted on the upper two wires of the four-split wire, and the drone disconnects the connection of the first hook 6, and the inspection box 1 and the fixed bracket 31 descend relative to the walking assembly due to their own weight, causing the first elastic member 37 to produce elastic deformation, thereby driving the movable bracket 32 ​​to rotate relative to the fixed bracket 31 through the transmission assembly until it is engaged with the card slot, see Figure 1 , Figure 2 , so that the two ends of the wheel axle 35 of the walking assembly are connected to the inspection box 1 through the fixed bracket 31 and the movable bracket 32 ​​respectively, and the wheel axle 35, the movable bracket 32, the fixed bracket 31 and the inspection box 1 surround the four-split conductor to prevent the device from falling from the conductor when encountering crosswind.

[0036] When the device is removed from the wire, the drone hooks the first hook 6 and lifts the device, and the elastic force of the first elastic member 37 restores the deformation to move the walking assembly downward relative to the fixed bracket 31, so that the movable bracket 32 ​​is rotated out of the slot and attached to the inspection box 1 through the transmission assembly. Figure 8 When the running wheel 36 is just completely separated from the wire, the drone moves horizontally, so that the device can be removed from the wire.

[0037] The present invention can not only be mounted on the conductor by tools such as drones to facilitate the raising and lowering of the conductors and reduce the risk of operation, but can also automatically provide a movable bracket 32 ​​for the walking component to protect it from falling.

[0038] In another embodiment provided by the present invention, each mounting unit 3 also includes a locking mechanism 4, which is equipped to lock the movable bracket 32 ​​in the slot and unlock it when the movable bracket 32 ​​is engaged with the slot. The purpose is to further lock the movable bracket 32 ​​in the slot after the traveling assembly is mounted on the conductor. Because the traveling assembly may generate bumps and vibrations when passing through obstacles such as the connecting pipe and the four-split fixer on the conductor, there is a small relative movement between the fixed bracket 31, causing the movable bracket 32 ​​to briefly rotate out of the slot. Although the movable bracket 32 ​​will quickly return to the slot under the action of gravity of the detection box, there are still certain hidden dangers.

[0039] For a specific technical solution, see Figure 4 , Figure 5 The locking mechanism 4 includes a sliding pin 41, a second elastic member 43, a guide member 44, a sliding column 47, a pull rope 48 and a second hook 49. The sliding pin 41 is slidably connected to the fixed block 34. One end of the sliding pin 41 has an inclined guide surface 42, and the inclined guide surface 42 faces the mouth of the card slot. The second elastic member 43 restores its deformation process to drive the sliding pin 41 to slide to the mouth of the blocking card slot. The second elastic member 43 is preferably a second compression spring sleeved on the sliding pin 41. One end of the second compression spring abuts against the fixed block 34, and the other end abuts against the end cap of the sliding pin 41. The guide member 44 is vertically slidably connected to the fixed rod 410 fixedly connected to the fixed block 34. The guide member 44 has a guide groove, see Figure 6 The guide groove includes a connected vertical groove 45 and an inclined groove 46 from bottom to top, a sliding column 47 is slidably connected in the guide groove, and it is best to have sliding damping between the sliding column 47 and the guide groove. It is best to have a horizontal sliding connection between the sliding column 47 and the fixed rod 410. One end of the pull rope 48 is fixedly connected to the sliding pin 41, and the other end is fixedly connected to the sliding column 47. The second hook 49 is fixedly connected to the guide member 44 through a support rod. The second hook 49 is located inside the first hook 6. The locking mechanisms 4 of the two mounting units 3 share the same guide member 44, sliding column 47 and second hook 49.

[0040] In this embodiment, when on the ground, the sliding pin 41 is blocked at the mouth of the slot under the elastic force of the second elastic member 43, the sliding column 47 is at the top of the inclined slot 46, the pull rope 48 is in a tensioned state, and there is a large gap between the second hook 49 and the top of the first hook 6, see Figure 7The first hook 6 is hooked by a drone or other tool to lift the entire device, so that the two walking wheels 36 of the walking assembly are mounted on the upper two wires of the four-split wire, and then the drone disconnects the first hook 6, and the inspection box 1 and the fixed bracket 31 are lowered relative to the walking assembly due to their own weight, causing the first elastic member 37 to produce elastic deformation, thereby driving the movable bracket 32 ​​to rotate toward the slot relative to the fixed bracket 31 through the transmission assembly. When the movable bracket 32 ​​rotates to the slot mouth, it squeezes the inclined guide surface 42 of the sliding pin 41, thereby overcoming the elastic force of the second elastic member 43 to squeeze the sliding pin 41 away from the slot mouth. After the movable bracket 32 ​​completely enters the slot, it is freed from the obstruction of the sliding pin 41, and the elastic force of the second elastic member 43 is released, allowing the sliding pin 41 to slide back to the slot mouth blocked, see Figure 1 , Figure 2 , thereby limiting the activity within the slot and improving the stability of the connection between the movable bracket 32 ​​and the fixed block 34. Even when passing through obstacles such as the connecting pipe and the four-split fixture, the movable bracket 32 ​​will not rotate out of the slot due to the limitation of the sliding pin 41. At this time, a small distance is still maintained between the top of the first hook 6 and the second hook 49.

[0041] When it is necessary to remove the device from the wire, the second hook 49 is hooked and lifted by the drone. In the process of the second hook 49 abutting against the top of the first hook 6, the lifted second hook 49 drives the guide member 44 to move upward relative to the fixed rod 410 through the support rod, so that the slide column 47 slides relatively from the top of the inclined groove 46 to the junction of the inclined groove 46 and the vertical groove 45, and the slide column 47 pulls the sliding pin 41 from the mouth of the slot through the pull rope 48, and the sliding pin 41 no longer blocks and restricts the movable bracket 32; when the second hook 49 abuts against the top of the first hook 6, as the drone continues to lift, the second hook 49 drives the first hook 6 to rise together, and the second hook 49 drives the fixed frame and the inspection box 1 to move upward relative to the walking assembly, so that the movable bracket 32 ​​is rotated out of the slot and fits onto the inspection box 1 through the transmission assembly, see Figure 8 , thereby enabling the device to be removed from the wire.

[0042] In the process of mounting the traveling assembly on the conductor, the rotating rod can smoothly squeeze the sliding pin 41 and enter the slot. After mounting on the conductor, the elastic force of the second elastic member 43 causes the sliding pin 41 to automatically return to the slot mouth to lock and restrict the movable bracket 32 ​​in the slot, thereby improving the stability of the device when crossing obstacles. When the traveling assembly is removed from the conductor, the sliding pin 41 can be automatically disengaged from the slot mouth to avoid the movable bracket 32, so that the movable bracket 32 ​​can be smoothly rotated out of the slot, which is very convenient.

[0043] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
