Description

Technical Field

[0001] The present invention relates to the technical field of transmission line monitoring, and particularly to an intelligent identification and detection device for insulator defects in transmission lines. Background Art

[0002] Traditional power grid transmission line inspection modes often require a large amount of human resources to be concentrated in carrying out operations such as operation and maintenance, repair, and power protection. At present, with the rapid development of the power grid, the shortage of professional human resources is becoming increasingly serious, and the external operation and maintenance environment is becoming increasingly harsh. The contradiction between the original inspection mode and the rapidly growing power grid scale is becoming increasingly prominent, and the operation and maintenance effectiveness needs to be greatly improved. At present, the more commonly used method is to install monitoring devices to achieve online monitoring of transmission lines.

[0003] However, for the existing additional measurement of the insulator surface core, it is necessary to place devices on the insulators at each connection of the transmission line. While wasting resources, it is necessary to monitor multiple feedback terminals. At the same time, the placement of the devices requires operators to place multiple insulators by climbing at one time, with poor safety and a waste of manpower and time, which is not conducive to actual use. Summary of the Invention

[0004] The purpose of the present invention is to solve the disadvantages existing in the prior art, and to propose an intelligent identification and detection device for insulator defects in transmission lines.

Detailed Implementation Manner

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the following combines specific embodiments and drawings to further elaborate the present invention. However, the following embodiments are only the preferred embodiments of the present invention, not all. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative efforts all belong to the protection scope of the present invention.

[0021] The following describes the specific embodiments of the present invention with reference to the drawings. Specific Embodiment:

[0023] Refer to Figures 1-4, a smart identification and detection device for transmission line insulator defects, including a detection box 1, a detection probe 3, a telescopic rod 7 and a sliding device 8. Inside the detection box 1, there is a first motor 5. The output shaft of the first motor 5 is fixedly provided with a first cylinder 6. The movable end of the first cylinder 6 penetrates through the back of the detection box 1 and is fixedly connected to the end of the telescopic rod 7. The top of the telescopic rod 7 is fixedly connected to the sliding device 8. The sliding device 8 includes a sliding outer shell 807, a second motor 801 and sliding wheels 805. The sliding wheels 805 are located inside the sliding outer shell 807 and are symmetrically distributed on both sides of the top and bottom of the inner surface of the sliding outer shell 807. The surface of the sliding wheels 805 is provided with limiting arc grooves 806. The limiting arc grooves 806 on the surfaces of the symmetric sliding wheels 805 are abutted to form a circle. The sliding device 8 on the top of the detection box 1 slides on the surface of the transmission line. The transmission line is clamped by the limiting arc grooves 806 on the surface of the sliding wheels 805. While the sliding device 8 is driven by the second motor 801 to slide, the surface of the insulator is detected by the detection probe 3, avoiding the danger of traditional manual climbing detection. By hanging and sliding, multiple insulators are detected in turn, which is simple and convenient, saving manpower and time, and easy to operate. The first motor 5, the first cylinder 6 and the micro linear motor group 803 of the sliding device 8, the second motor 801 and the second cylinder 802 are all electrically connected to the control terminal 4 inside the detection box 1. Linear chutes 804 are opened on both sides inside the sliding outer shell 807 of the sliding device 8. Inside one linear chute 804 on one side of the sliding outer shell 807, there is a micro linear motor group 803. The output shaft of the micro linear motor group 803 in the horizontal direction is fixedly connected to the inner wall of the linear chute 804 by a flat key. The output shaft of the micro linear motor group 803 in the vertical direction is fixedly provided with the second motor 801, and the fixing direction of the second motor 801 is perpendicular to the output shaft of the micro linear motor group 803 in the vertical direction. The output shaft of the second motor 801 is fixedly connected to the side surface of the sliding wheel 805. Pressure sensors are provided inside the sliding outer shell 807 of the sliding device 8. The cross-section of the sliding outer shell 807 is concave. While the transmission line enters the inside of the sliding outer shell 807, the pressure sensors inside the sliding outer shell 807 transmit electrical signals to the control terminal 4 inside the detection box 1. The control terminal 4 drives the output shaft of the micro linear motor group 803 in the vertical direction to contract. After driving the sliding wheels 805 to approach and abut against each other, the micro linear motor stops contracting. At this time, the transmission line is clamped and fixed by the limiting arc grooves 806 on the surfaces of the sliding wheels 805 on both sides. The control terminal 4 drives the second motor 801 to operate. The second motor 801 drives the entire sliding device 8 and the detection box 1 to slide on the surface of the transmission line. Second cylinders 802 are symmetrically provided inside the linear chute 804 on the side of the sliding outer shell 807 away from the micro linear motor group 803. The bottom surface of the second cylinders 802 is fixedly connected to the top and bottom of the linear arc groove. The end of the movable shaft of the second cylinder 802 is fixedly provided with a connecting shaft 808 in the vertical direction,One end of the connecting shaft 808 away from the second cylinder 802 is fixedly connected to the center position of the side of the sliding wheel 805 away from the second cylinder 802. When the miniature linear motor group 803 contracts to limit and fix the power transmission line, the movable shaft of the second cylinder 802 extends under the drive of the miniature linear motor group 803. After the miniature linear motor group 803 stops operating, the second cylinder 802 presses on the sliding wheel 805 through the connecting shaft 808 to keep the sliding wheel 805 always pressing on the power transmission line during forward rotation transmission, maintaining the position stability of the power transmission line. Placement grooves 2 are provided on both the front and back of the detection box 1. Detection probes 3 are provided inside the placement grooves 2. A control terminal 4 is provided inside the detection box 1. The detection probes 3 are electrically connected to the control terminal 4. The detection probes 3 are used to detect the cracks, softening degree, corrosion degree, surface stains, etc. on the surface of the insulator. By feeding back the electrical signal results to the control terminal 4, the control terminal 4 is connected to external devices to transmit the detection result signal of the insulator to the external devices, facilitating the operators not to climb to the surface of the insulator to observe the situation and facilitating the timely maintenance of the operators. A limiting groove 9 is provided on the back of the detection box 1. The movable shaft of the first cylinder 6 is fixed to the telescopic rod 7 through the limiting groove 9, and the outer wall of the movable shaft of the first cylinder 6 abuts against the inner wall of the limiting groove 9. The limiting groove 9 keeps the detection box 1 stable when the sliding device 8 is suspended on the surface of the power transmission line. The first motor 5, the first cylinder 6, the telescopic rod 7, the limiting groove 9, and the sliding device 8 are all provided in two, symmetrically distributed along the horizontal center plane of the front of the detection box 1. After the device detects the first insulator, it needs to continue moving forward to detect the insulator at the next position. After detecting obstacles on the surface of the detection box 1, an electrical signal is transmitted to the control terminal 4. The control terminal 4 drives the first cylinder 6 to operate. The movable shaft of the first cylinder 6 extends, driving the bottom telescopic rod 7 and the sliding device 8 to drive forward. Through the rotation of the first motor 5, the sliding device 8 at the bottom rotates 180 degrees to the top to complete the clamping and fixing with the power transmission line on the other side of the insulator. Then, the detection device originally at the top is driven by the control terminal 4, and the vertical output shaft of the miniature linear motor group 803 extends, driving the sliding wheel 805 to move towards the inner top and bottom surfaces of the sliding housing 807. The sliding wheel 805 no longer limits and fixes the power transmission line. The first motor 5 at the top of the detection box 1 drives the first cylinder 6 and the sliding device 8 to rotate 180 degrees in the reverse direction, separating the sliding device 8 from the power transmission line. The device continues to move forward for detection under the drive of the sliding device 8 on the other side until all insulators are detected. When the device stops running and the operator removes the device, the detection process is completed. Waterproof and insulating coatings are provided on the outer part of the detection box 1 and the outer wall of the sliding housing 807 of the sliding device 8. The edges of the detection box 1 and the sliding housing 807 are all treated with rounded corners to prevent the device from being damaged due to rainwater penetration and equipment damage during external work, protecting the device.
