Detailed implementation manners

[0028] The following further elaborates the present invention in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by this application.

[0029] The present invention relates to an automatic inspection device for a substation site. The main structure includes a track 2 arranged inside the site enclosure 1. The site enclosure 1 is a wall structure surrounding the outside of the substation site, used to protect the substation's electrical equipment. The site enclosure 1 is generally square in shape. The track 2 is fixed to the inside of the site enclosure 1 by welding or bolts and is also in a circular structure. A movable support 3 is provided on the track 2, and the support 3 can move along the track 2. A monitor 4 is provided on the support 3. The monitor 4 can use any structure with photographing and video recording functions in the prior art. By using the movement of the support 3 along the track 2, the monitor 4 can move around the substation site, realizing effective inspection of equipment at various positions. The monitor 4 has a telephoto function and can magnify distant equipment to ensure the clarity and monitoring effect of the monitoring. A plurality of tracks 2 are arranged along the inside of the site enclosure 1, and adjacent tracks 2 are arranged vertically. A steering seat 5 is provided between adjacent tracks 2. When the support 3 moves linearly along the site enclosure 1 and reaches the corner of the site enclosure 1, it needs to change direction. At this time, the support 3 moves to the steering seat 5 connected to the track 2. The steering seat 5 is rotatably connected to the site enclosure 1. The two ends of the steering seat 5 are respectively connected to adjacent two tracks 2 before and after rotation. With such a setting, after the support 3 moves to the steering seat 5, the steering seat 5 rotates and is connected to the adjacent vertical track 2, and the support 3 can continue to move to the adjacent track 2 to achieve the steering effect, making the movement of the support 3 smoother, enabling smooth mobile inspection around the substation site, and improving the inspection range and inspection flexibility;

[0030] The bottom of the support 3 is provided with rollers 6, and a motor 7 for driving the rotation of the rollers 6 is arranged on the support 3. Specifically, two rotating shafts can be arranged on the support 3, and the two rotating shafts are connected by meshing transmission gears. The output shaft of the motor 7 is connected to one of the rotating shafts, and the roller 6 is fixed on the other rotating shaft to realize the rotational drive of the roller 6 by the motor 7. The roller 6 can roll and move on the top of the connected whole composed of the track 2 and the steering seat 5. A power assembly for driving the rotation of the steering seat 5 is arranged on the inner side of the site enclosure wall 1. The steering seat 5 and the power assembly are arranged at each position of the site enclosure wall 1. An action contact 8 for controlling the action of the power assembly is arranged on the top of the steering seat 5. The action contact 8 and the power assembly are in the same circuit. When the action contact 8 is closed, the circuit where the power assembly is located is connected, and the power assembly acts to drive the steering seat 5 to perform a steering operation. When the roller 6 contacts the action contact 8, the power assembly is turned on. Such a setting, after the support 3 moves from the track 2 to the steering seat 5, rolls and contacts the action contact 8, so that after the power assembly is energized, it drives the steering seat 5 to automatically rotate and automatically connect to another track 2. As the support 3 continues to move, it moves from the steering seat 5 to another track 2, realizing the automatic steering of the steering seat 5, thereby making the movement of the support 3 on the entire annular track 2 smoother, without the need for manual control. The automatic steering of the support 3 is realized by the physical contact between the roller 6 and the action contact 8, ensuring the flexibility of the movement of the support 3 and improving its service life for inspection;

[0031] Inside the inner side of the site enclosure wall 1, there is a power support plate 9. The power support plate 9 is in a shape that cooperates with the track 2 and is fixed to the inner side of the site enclosure wall 1 through an insulating component. On the power support plate 9, there is a power supply conductor plate 10. The power supply conductor plate 10 is arranged along the movement track of the support 3 and is connected to the power supply system, that is, the commercial power. A support rod 11 is slidably connected to the support 3. The sliding direction of the support rod 11 is perpendicular to that of the support 3. A first compression spring 12 is arranged between the support rod 11 and the support 3. A contact wheel 13 is rotatably connected to the support rod 11. The contact wheel 13 is in rolling contact with the power support plate 9. Under the elastic force of the first compression spring 12, the contact wheel 13 on the support rod 11 always maintains rolling contact with the power support plate 9. An electric contact piece 14 electrically connected to the monitor 4 and the motor 7 is arranged on the support rod 11. The electric contact piece 14 is a conductor component and is in the same circuit as the monitor 4 and the motor 7. The electric contact piece 14 is in contact with the power supply conductor plate 10. On the premise that the support rod 11 always maintains rolling contact with the power support plate 9 through the contact wheel 13, the position of the support rod 11 during the movement of the support 3 is ensured. Thus, the electric contact piece 14 on the support rod 11 can also always maintain a contact state with the power supply conductor plate 10. As a result, the monitor 4 and the motor 7 are always in a powered state, enabling the movement of the support 3 on the track 2 and the monitor 4 to maintain a powered operation state. As long as the commercial power does not stop, there is no problem with battery life, ensuring the continuous and accurate monitoring effect of the monitoring device.

[0032] Preferably, a plurality of fixing plates 15 are welded or bolt-fixed to the inner side of the site enclosure wall 1. A rotating shaft 16 is rotatably connected to the fixing plates 15. The steering seat 5 is welded or bolt-fixed to the top of the rotating shaft 16. The power component is used to drive the rotation of the rotating shaft 16. With such a setting, only by driving the rotating shaft 16 to rotate a specified angle, the steering seat 5 at the top can be rotated to communicate with another track 2, making the rotation drive of the power component easier to control and achieve.

[0033] Preferably, the power assembly is an electric cylinder 17 disposed on the fixed plate 15. The electric cylinder 17 is a telescopic rod structure that uses electricity as an energy source. The moving contact 8 is used to control the operation of the electric cylinder 17, that is, to control the extension and contraction of the electric cylinder 17. A toothed plate 18 is slidably connected to the fixed plate 15. Specifically, a chute is provided on the fixed plate 15, and the toothed plate 18 is slidably connected in the chute to ensure the directionality of the sliding. The toothed plate 18 is welded or bolted to the movable end of the electric cylinder 17. A gear 19 is provided on the rotating shaft 16, and the gear 19 meshes with the toothed plate 18. In such a structure, when the roller 6 contacts the moving contact 8, the electric cylinder 17 is powered on and starts to extend, driving the toothed plate 18 to slide a certain distance, driving the gear 19 meshing with it to rotate a certain angle, and then causing the swivel base 5 at the top of the rotating shaft 16 to rotate a specified angle and coincide with the track 2. It can be achieved only by setting the telescopic length of the electric cylinder 17 in advance, making the rotation control of the swivel base 5 more accurate.

[0034] Preferably, a groove 20 is provided at the top of the swivel base 5. The groove 20 is recessed downward from the top of the swivel base 5. The moving contact 8 is slidably connected vertically in the groove 20. The moving contact 8 can slide out of the top of the swivel base 5 or hide inside the groove 20. A second compression spring 21 is provided between the moving contact 8 and the bottom of the groove 20. Under the connection of the second compression spring 21, the moving contact 8 is normally in a state of protruding from the top of the swivel base 5. Preferably, the top of the moving contact 8 is arc-shaped to better contact the roller 6. A static contact 22 electrically connected to the electric cylinder 17 is provided at the bottom of the groove 20. When the moving contact 8 contacts the static contact 22, the electric cylinder 17 is opened to extend. In such a setting, after the support 3 moves onto the swivel base 5, the arc-shaped inclined surface of the roller 6 rolls into contact with the protruding moving contact 8, thereby pressing the moving contact 8 to slide downward, causing the moving contact 8 to contact the static contact 22 at the bottom, making the circuit where the electric cylinder 17 is located connected, so that after the electric cylinder 17 extends a certain length, the automatic rotation drive of the swivel base 5 is realized, and the opening control of the extension of the electric cylinder 17 is achieved. After the support 3 moves from the swivel base 5 to the track 2, the moving contact 8 automatically resets under the action of the second compression spring 21 and separates from the static contact 22 at the bottom. A static contact for controlling the contraction of the electric cylinder 17 is also provided at the top of the groove 20. After the moving contact 8 resets, it contacts the static contact at the top to control the contraction of the electric cylinder 17, causing the swivel base 5 to rotate in the reverse direction and reset, realizing the opening control of the contraction of the electric cylinder 17, thus meeting the automatic control of the extension and contraction of the electric cylinder 17 through physical contact, with more accurate control, less likely to have system errors, and ensuring the accuracy of the steering control of the swivel base 5.

[0035] Preferably, limiting steps 23 are provided at the tops of the track 2 and the swivel base 5, and the top of the support 3 is in sliding contact with the limiting steps 23. Such a setting makes the relative position between the support 3 and the track 2 stable vertically, so that after the support 3 enters the swivel base 5, the roller 6 can smoothly press the moving contact 8 to make it slide up and down, thereby ensuring the accuracy of the moving contact 8 in controlling the elongation or contraction of the electric cylinder 17.

[0036] Preferably, a scissor telescopic member 24 is provided on the support 3. The scissor telescopic member 24 is driven by an electric cylinder, and it occupies a narrower area when contracted, which can facilitate the smooth movement of the support 3 along the site enclosure wall 1. A fixing bracket 25 is provided at the end of the scissor telescopic member 24, and the monitor 4 is arranged on the fixing bracket 25. A telephoto lens is provided on the monitor 4. Such a setting can, during the monitoring process, through the elongation of the scissor telescopic member 24, make the monitor 4 extend near the equipment to be inspected, so as to observe the situation of the equipment in more detail, improve the effect of inspection. At the same time, the setting of the telephoto lens can observe the situation of the equipment in the distance that cannot be reached more clearly, and overall improve the accuracy of the inspection and monitoring of the equipment at each position.

[0037] Preferably, an avoidance groove 26 is provided on the fixing bracket 25. One side of the monitor 4 is rotatably connected to the inner side wall of the avoidance groove 26 through a pin shaft or a hinge. A torsion spring 27 is provided between the monitor 4 and the inner side wall of the avoidance groove 26. Under the action of the torsion spring 27, the monitor 4 is in contact with one side wall of the avoidance groove 26 to achieve the monitoring effect of the site equipment. During the movement of the support 3 driving the monitor 4, if the monitor 4 touches an obstacle or equipment, the monitor 4 can rotate and hide in the avoidance groove 26, and the avoidance groove 26 of the fixing bracket 25 effectively protects the monitor 4, avoiding damage to the monitor 4 during the inspection process, and improving the service life of the device and the smoothness of the inspection process.

[0038] Preferably, a fixing sleeve 28 is welded or bolt-fixed on the support 3. The support rod 11 is slidably connected inside the fixing sleeve 28. The first compression spring 12 is located between the support rod 11 and the inner side of the fixing sleeve 28. Such a setting makes the sliding direction of the support rod 11 relative to the support 3 more stable, so that it is not easy to bend when moving to the corner of the site enclosure wall 1, thereby maintaining the stability of the relative sliding with the support 3 and making the electric contact piece 14 on it keep accurate contact with the power supply conductor plate 10.

[0039] Preferably, a limiting plate 29 for cooperating with the steering seat 5 is provided on the side surface of the track 2. The setting of the limiting plate 29 can limit the position of the rotated steering seat 5, so that it remains in a connected state with the track 2, enabling the support 3 to smoothly move from the steering seat 5 to the track 2, avoiding the dislocation between the steering seat 5 and the track 2 after rotation, improving the accurate cooperation between the steering seat 5 and the track 2 after steering, and enhancing the accuracy and smoothness of the movement of the support 3.

[0040] Preferably, the electric contact piece 14 is made of an elastic material. Specifically, a conductive metal elastic piece support can be used, so that it can undergo small elastic deformation when encountering uneven positions of the power supply conductor plate 10, ensuring accurate contact with the power supply conductor plate 10. At the same time, it is not easily broken due to deformation, ensuring the continuity and accuracy of power supply. One end of the electric contact piece 14 is provided with an arc portion 30, and the arc portion 30 is in sliding contact with the power supply conductor plate 10. The setting of the arc portion 30 makes the contact area between the electric contact piece 14 and the power supply conductor plate 10 larger, and the area of the contact position is always maintained during the relative sliding movement, further ensuring the accuracy of mobile power supply.

[0041] Working principle: In the present invention, a track 2 is arranged inside the site enclosure wall 1 of a substation. A movable support 3 is arranged on the track 2. A monitor 4 for monitoring and inspection is arranged on the support 3. The support 3 drives the roller 6 to rotate under the drive of a motor 7, so that the support 3 moves on the track 2 to monitor the equipment conditions in the site, realizing efficient and automatic inspection operations, reducing the working intensity of inspection, and improving the inspection efficiency. When the support 3 moves to the corner of the site enclosure wall 1, it moves from the track 2 to the steering seat 5. The steering seat 5 is driven to rotate by a power component. When the support 3 moves to the steering seat 5, the roller 6 at the bottom of the support 3 contacts the action contact 8 on the steering seat 5, controlling the power component to act to realize the automatic rotation of the steering seat 5, so that the support 3 is transferred from one track 2 to an adjacent vertical track 2, enabling the monitor 4 to move smoothly within the enclosure range of the site enclosure wall 1, thus being able to timely monitor the equipment conditions at various positions in the site, with a larger inspection range, smoother movement, and more accurate inspection results. A power support plate 9 is arranged inside the site enclosure wall 1. A power supply conductor plate 10 connected to the mains power is arranged on the power support plate 9. A support rod 11 is slidably arranged on the support 3. A first compression spring 12 is arranged between the support rod 11 and the support 3. A contact wheel 13 is rotatably arranged on the support rod 11. The contact wheel 13 is in rolling contact with the power support plate 9. An electric contact piece 14 electrically connected to the monitor 4 and the motor 7 is arranged on the support rod 11. The electric contact piece 14 is in contact with the power supply conductor plate 10. Such a setting enables the electric contact piece 14 for providing power to the monitor 4 and the motor 7 assembly to always maintain a connection state with the power supply conductor plate 10 under the action of the support rod 11, the first compression spring 12, and the contact wheel 13 when the support 3 moves inside the site enclosure wall 1, thereby realizing continuous power supply to the monitor 4 and the motor 7 driving the support 3 to move. There is no need to use a self - contained battery structure, and there is no problem of insufficient battery life. It can realize long - term continuous and accurate inspection operations for a substation site with a large area, greatly improving the adaptability for the inspection of the substation site.
