Description

Technical Field

[0001] The present invention belongs to the technical field of monitoring devices, and particularly relates to a monitoring device and an operation method for live high-altitude operation in a distribution network. Background Art

[0002] In a distribution network line, since operations such as repair, testing, and maintenance of the line and equipment are required, and power outage operations will affect the normal power consumption of users, live high-altitude operation has become an important operation method. The safety of high-altitude operation has always been the top priority in power operations. However, due to the difficulty in supervising high-altitude operation, especially in live repair operations, in order to speed up the repair progress, operators sometimes do not operate according to basic safety operation procedures, and illegal operations occur frequently. This not only increases the safety risks of individuals and teams, but also may cause casualties of operators, equipment damage, power supply interruption, economic losses, etc. In live operation of a distribution network, it is necessary to monitor the operation site in real time to ensure the safety and smooth progress of the operation. Existing monitoring devices have disadvantages such as inconvenient installation and disassembly, a small movable range of the camera, limited vision, and monitoring blind spots, which are not conducive to the supervision of high-altitude operation. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a monitoring device and an operation method for live high-altitude operation in a distribution network to solve the problems raised in the background art.

[0004] The purpose of the present invention is achieved as follows: A monitoring device for live high-altitude operation in a distribution network includes a traction seat and a lifting frame. The traction seat is placed above the cross arm, the lifting frame is clamped outside the electric pole. A lifting ring is arranged on the upper side of the traction seat, an electric winch is arranged on the front side of the traction seat, a winch rope is arranged outside the electric winch, a hook is arranged at the end of the winch rope, a pulling ring is arranged on the upper side of the lifting frame, and the pulling ring cooperates with the hook. A rack is arranged on the lower side of the lifting frame, a displacement platform is clamped and arranged below the lifting frame, a displacement motor is fixedly arranged on the upper side of the displacement platform, a driving gear is arranged at the output end of the displacement motor, and the driving gear meshes with the rack. A monitor is arranged below the displacement platform.

[0005] A rope clamping wheel is arranged on the right side of the electric winch, and the winch rope passes through the middle of the rope clamping wheel.

[0006] A limiting groove is arranged inside the lifting frame, a limiting rod is arranged on the upper side of the displacement platform, and the limiting rod cooperates with the limiting groove.

[0007] A positioning mechanism is arranged inside the towing seat. A placement groove is arranged in the middle of the towing seat. A guide plate is arranged below the placement groove. The placement groove is clamped above the cross arm. The positioning mechanism includes a clamping block and a driving block. A clamping arm is arranged below the clamping block. A driving block is arranged between the clamping blocks. A top head is arranged below the driving block. A return spring is arranged between the upper part of the driving block and the towing seat.

[0008] One side of the clamping block and the driving block close to each other is inclined.

[0009] An inner groove is arranged inside the clamping block. An insertion block is arranged on the outer side of the driving block. The insertion block and the inner groove cooperate with each other.

[0010] The lifting frame includes an upper supporting ring and a lower clamping ring. The pulling ring is fixedly arranged on the upper supporting ring. A connecting platform is arranged on the outer side of the upper supporting ring. The shifting platform is movably arranged on the lower clamping ring. The lower clamping ring includes symmetric semi-rings. The ends of the two semi-rings are fixed by a buckle. A connecting rod is hinged on the outer side of the buckle. The connecting rod is fixed to the connecting platform by a nut.

[0011] An expansion rod is arranged inside the upper supporting ring. The expansion rod is fixed to the upper supporting ring by a positioning knob. Universal balls are arranged on the inner sides of the upper supporting ring and the expansion rod.

[0012] A pressing plate is arranged on the inner side of the lower clamping ring. An extrusion spring is arranged between the pressing plate and the lower clamping ring. A roller is arranged on the inner side of the pressing plate.

[0013] An operation method of a live working monitoring device for distribution network includes the following steps: Step 1: Before operation, the whole device needs to be checked to ensure that components such as the towing seat, lifting frame, electric winch shifting platform, monitor, etc. are in good condition without damage or looseness. Step 2: Place the towing seat above the cross arm through a drone. Through the positioning mechanism inside the towing seat, the towing seat can be firmly clamped on the cross arm. Remotely control the electric winch to make the winch rope extend and drive the hook to move downward. Step 3: Clamp the lifting frame with the electric pole so that the upper supporting ring and the lower clamping ring can be tightly connected to the electric pole. Connect the hook with the pulling ring on the outer side of the lifting frame. Tighten the winch rope through the electric winch. The hook drives the lifting frame to move along the electric pole to a suitable height, and the monitor can be used for monitoring work. Step 4: After the operation is completed, control the electric winch to make the winch rope extend, drive the lifting frame to move down to the bottom of the electric pole, remove the lifting frame from the lower side of the electric pole, then remove the towing seat from above the cross arm through a drone, organize and store the device, and recycle the tool equipment.

[0014] Advantages of the present invention: When the device is in use, through the positioning mechanism inside the traction seat, the traction seat can be firmly clamped on the cross arm, effectively preventing possible shaking or falling during high-altitude operations, thus greatly improving the safety of the operations. The traction seat can be installed and disassembled by a drone. The design of the electric winch and the winch rope enables the operator to remotely control the lifting of the lifting frame, avoiding the safety risks brought by directly climbing the electric pole. The cooperation of the displacement motor, the drive gear and the rack enables the displacement platform to move smoothly on the electric pole, facilitating the monitoring and operation of the monitor at different heights and angles. The monitor is arranged below the displacement platform and can record and transmit the situation at the operation site in real time, facilitating real-time monitoring and guidance by ground personnel, thereby improving the operation efficiency and operation safety. The telescopic rod and the positioning knob inside the upper support ring allow the operator to easily sleeved the upper support ring outside the electric pole, further enhancing the flexibility of the operation. The design of the pressure plate and the roller enables stable contact and support between the lower clamping ring and the electric pole, further enhancing the adaptability and stability of the device.

The towing seat 1 and the cross arm 19 are clamped to each other. The lifting frame 2 is sleeved outside the electric pole. The electric winch 4 is started, and the winch rope 6 is pulled out to an appropriate length.

Under the action of the driving block 24, the clamping blocks 22 start to move inward, and the clamping arms 23 on both sides gradually approach the cross arm 19 to ensure that the clamping arms 23 can firmly clamp the cross arm 19. When it is necessary to remove the towing seat 1 from the upper side of the cross arm 19, the drone lifts the towing seat 1 through the lifting ring 3. At this time, the towing seat 1 is no longer affected by gravity, and the return spring 26 pushes the driving block 24 downward, thereby moving the clamping blocks 22 away from each other. At this time, the clamping arms 23 are away from the cross arm 19, and the towing seat 1 can be easily removed.

[0050] An operation method of a live working high-altitude monitoring device for distribution network includes the following steps: Step 1: Before operation, it is necessary to check the entire device to ensure that components such as the traction seat 1, lifting frame 2, electric winch 4, shifting platform 12, monitor 15, etc. are all in good condition without damage or looseness. Step 2: Place the traction seat 1 above the cross arm 19 through a drone. Through the positioning mechanism inside the traction seat 1, the traction seat 1 can be firmly clamped on the cross arm 19. Remotely control the electric winch 4 to extend the winch rope 6 and drive the hook 7 to move downward. Step 3: Connect the lifting frame 2 with the pole in a clamping manner, so that the upper supporting ring 8 and the lower clamping ring 9 can be tightly connected to the pole. Connect the hook 7 with the pulling ring 16 on the outer side of the lifting frame 2. Tighten the winch rope 6 through the electric winch 4. The hook 7 drives the lifting frame 2 to move along the pole to an appropriate height, and the monitor 15 can be used for monitoring work.

[0051] When the present invention is in use, a drone is utilized to drive the traction seat 1 to rise through the hanging ring 3, and the traction seat 1 is placed above the cross arm 19, and the traction seat 1 and the cross arm 19 are engaged with each other. The lifting frame 2 is sleeved outside the electric pole, the electric winch 4 is started, the winch rope 6 is pulled out to an appropriate length, the hook 7 at the end of the winch rope 6 is connected to the upper pull ring 16 on the lifting frame 2, and the electric winch 4 is started to retract the winch rope 6, and the winch rope 6 drives the lifting frame 2 to rise along the electric pole.

According to the operation requirements, the position of the displacement platform 12 is adjusted so as to align the monitor with the target area, and 360° dead-angle-free monitoring can be carried out. According to the operation requirements, the angle and position of the monitor 15 can be adjusted in real time so as to obtain a clearer monitoring picture.

Step 4: After the operation is completed, control the electric winch to extend the winch rope, drive the lifting frame to move downward to the bottom of the electric pole, remove the lifting frame from the lower side of the electric pole, then remove the towing seat from above the cross arm through a drone, organize and store the device, and recycle tools and equipment.
