Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of electric power operation and maintenance equipment maintenance, specifically is a kind of electric power operation and maintenance safety monitoring device. BACKGROUND

[0002] In the operation and maintenance work of modern power system, the safe and stable operation of power equipment is the key to uninterrupted power supply, with the continuous expansion of power network and the continuous development of power technology, the number of power equipment is increasing, and its distribution range is more and more extensive, which makes the power operation and maintenance work face unprecedented challenges.

[0003] The traditional power operation and maintenance monitoring mode mainly depends on the monitoring equipment installed in fixed position, these fixed monitoring equipment exposes many limitations in actual application, first, its monitoring range is extremely limited, only specific direction and area can be covered, and power equipment cannot be monitored in all directions.

[0004] Secondly, fixed monitoring equipment lacks flexibility, and cannot dynamically adjust monitoring angle and position according to actual demand. When specific equipment needs to be monitored or when equipment needs to be observed from different angles, fixed monitoring equipment cannot quickly respond and make corresponding adjustment. This largely limits the accurate judgment of operation and maintenance personnel on the running condition of power equipment and the timely intervention ability, increases the risk of power accident and the difficulty of accident handling.

[0005] Furthermore, with the development trend of intelligent power operation and maintenance, higher requirements are put forward for the comprehensiveness, accuracy and timeliness of monitoring data. The single-angle, single-position monitoring data obtained by traditional fixed monitoring equipment can not meet the demand of comprehensive analysis and fault prediction of power equipment. For example, when analyzing the heating fault of power equipment, the thermal imaging data obtained from a fixed direction may not accurately reflect the overall temperature distribution of the equipment, thereby affecting the assessment of fault severity and accurate positioning of fault cause.

[0006] In summary, in order to effectively improve the efficiency and quality of power operation and maintenance, and ensure the safe and stable operation of power system, a new type of power operation and maintenance safety monitoring device is urgently needed to overcome the limitations of traditional monitoring equipment. The device should have multi-degree-of-freedom motion capability, can realize omnidirectional, multi-angle, dynamic flexible monitoring of power equipment, and can be closely combined with intelligent monitoring system to provide more abundant, more accurate and more timely monitoring data support for power operation and maintenance work.

[0030] As an alternative to embodiment 1, the circumferential rotating frame 2 is provided with an angle sensor, and the angle sensor is electrically connected to the controller.

[0031] As an alternative to embodiment 1, the longitudinal rotating frame 4 is provided with a stroke limit switch, and the stroke limit switch is electrically connected to the controller.

[0032] In use,

[0033] Device assembly: first, place the fixed frame 1 in the predetermined power operation and maintenance monitoring site, adjust the fixed frame 1 to a horizontal state by the adjustable height anchor bolts on the fixed frame 1, and ensure the stability and flatness of the entire device installation foundation.

[0034] Fix the first motor 9 on the fixed frame 1, then firmly connect the output end of the first motor 9 with the circumferential rotating frame 2, so that the circumferential rotating frame 2 can rotate circumferentially around the fixed frame 1 under the drive of the first motor 9, and the angle sensor on the circumferential rotating frame 2 is electrically connected to the controller to accurately monitor the rotation angle information of the circumferential rotating frame 2 and feed back to the controller.

[0035] Fix the connecting frame 3 on the circumferential rotating frame 2, then install two sets of longitudinal rotating frames 4 on the connecting frame 3, ensure that the auxiliary gears 11 at the rotating ends of the two sets of longitudinal rotating frames 4 mesh well with each other to ensure synchronous rotation of the two sets of longitudinal rotating frames 4, fix the second motor 10 on the connecting frame 3, and connect its output end with the longitudinal rotating frame 4, so that the longitudinal rotating frame 4 can rotate longitudinally relative to the connecting frame 3 under the drive of the second motor 10, and the stroke limit switch on the longitudinal rotating frame 4 is electrically connected to the controller to limit the sliding range of the monitoring fixed frame 5 on the longitudinal rotating frame 4.

[0036] The inner gear 6 is installed on the inner side wall of the longitudinal rotating frame 4, the monitoring fixed frame 5 is slidably connected to the longitudinal rotating frame 4, and the outer gear 7 is rotatably connected to the monitoring fixed frame 5 and meshes with the inner gear 6, the third motor 12 is fixed to the monitoring fixed frame 5, and the output end of the third motor 12 is connected to the rotating shaft of the outer gear 7, so that the third motor 12 drives the outer gear 7 to rotate, thereby driving the monitoring fixed frame 5 to slide on the longitudinal rotating frame 4, and finally, the monitoring device 8 is installed at the bottom of the monitoring fixed frame 5, which can be a combination of a high-definition camera and an infrared thermal imager, and the monitoring device 8 is electrically connected to the controller to transmit the collected monitoring data to the controller for processing and analysis.

[0037] The monitoring operation process is as follows: after starting the monitoring device, the controller controls the first motor 9 to start according to the preset monitoring program or remote monitoring instruction, and the first motor 9 drives the circumferential rotating frame 2 to rotate slowly and stably around the fixed frame 1, for example, when the power equipment in the substation is scanned and monitored comprehensively, the circumferential rotating frame 2 can rotate at a speed of 10-15 degrees per minute, and the angle sensor transmits the current angle information of the circumferential rotating frame 2 to the controller in real time, and the controller ensures that the circumferential rotating frame 2 rotates accurately according to the predetermined trajectory, so that the monitoring device 8 can scan and monitor the power equipment in different areas of the substation in the horizontal direction.

[0038] When it is necessary to monitor the power equipment at a certain height or area more carefully in the vertical direction, the controller starts the second motor 10, and the second motor 10 drives the longitudinal rotating frame 4 to rotate relative to the connecting frame 3, and since the two groups of longitudinal rotating frames 4 are meshed with each other through the auxiliary gear 11, they will rotate synchronously to ensure that the monitoring device 8 is adjusted stably and uniformly in the vertical direction, for example, when a transformer with a higher voltage level is monitored comprehensively from the top and side, the longitudinal rotating frame 4 can be rotated 30-60 degrees upward from the horizontal position under the drive of the second motor 10, so that the monitoring device 8 can obtain image and thermal imaging data at different angles on the top and side of the transformer, and during the rotation of the longitudinal rotating frame 4, the travel limit switch continuously monitors the position of the monitoring fixed frame 5 to prevent it from exceeding the preset safe sliding range.

[0039] If further adjustment of the distance of the monitoring device 8 in the longitudinal direction relative to the power equipment is required to obtain clearer or specific range monitoring data, the controller controls the third motor 12 to start, and the third motor 12 drives the outer gear 7 to rotate. Since the outer gear 7 is engaged with the inner gear 6 on the inner side wall of the longitudinal rotating frame 4, the monitoring fixed frame 5 will slide on the longitudinal rotating frame 4. For example, when a close-up monitoring of a certain key connection part of the power equipment is required, the third motor 12 drives the monitoring fixed frame 5 to slide forward, so that the monitoring device 8 is close to the target part, and more detailed image and thermal imaging information is obtained.

[0040] Working principle

[0041] Circumferential rotation movement principle: the first motor 9 is the power source of the circumferential rotating frame 2. When the controller sends a control signal to start the first motor 9, the output shaft of the first motor 9 rotates. Since it is fixedly connected with the circumferential rotating frame 2, according to the principle that force is mutual and rotation is transmitted, the circumferential rotating frame 2 will rotate circumferentially around the rotating connection point with the fixed frame 1. The angle sensor monitors the rotation angle of the circumferential rotating frame 2 in real time and transmits the angle data to the controller. The controller adjusts the rotation speed and direction of the first motor 9 in real time by comparing the preset angle value or the target angle value calculated according to the monitoring requirements, so as to realize accurate positioning and rotation control of the circumferential rotating frame 2, and enable the monitoring device 8 to cover the required monitoring area in the horizontal direction.

[0042] Longitudinal rotation principle: the second motor 10 provides power for the longitudinal rotating frame 4. When the controller controls the second motor 10 to operate, the rotation of the output shaft of the second motor 10 drives the longitudinal rotating frame 4 to rotate relative to the connecting frame 3. The two sets of auxiliary gears 11 on the rotating ends of the longitudinal rotating frames 4 are engaged with each other. This engagement relationship ensures the synchronization and coordination of the two sets of longitudinal rotating frames 4 during rotation. When one set of longitudinal rotating frame 4 rotates, the other set of longitudinal rotating frame 4 will rotate at the same speed and in the same direction through gear engagement transmission, so that the monitoring device 8 can be adjusted smoothly in the vertical direction to realize effective monitoring of power equipment at different heights. The travel limit switch monitors the position of the monitoring fixed frame 5 during the rotation of the longitudinal rotating frame 4. When the monitoring fixed frame 5 approaches the boundary position of the longitudinal rotating frame 4, the travel limit switch sends a signal to the controller, and the controller immediately stops the operation of the second motor 10 to prevent the monitoring fixed frame 5 from sliding out of the longitudinal rotating frame 4 and avoid damage to the device.

[0043] The whole cooperative working principle: in the whole monitoring process, the controller plays a core control and coordination role, according to the preset monitoring strategy, the instruction of the remote operator and the information fed back by various sensors (such as the angle information of the angle sensor, the position information of the travel limit switch, etc.), the running state of the first motor 9, the second motor 10 and the third motor 12 is accurately controlled, the circumferential rotating frame 2, the longitudinal rotating frame 4 and the monitoring fixed frame 5 are cooperated with each other, the data such as the image and the thermal image of the electric power equipment collected by the monitoring equipment 8 at different positions and angles are transmitted to the controller through the electrical connection with the controller, the controller can preliminarily process and analyze these data, such as judging whether the electric power equipment exists abnormal heating or not, whether the appearance is damaged or not, and further adjusting the monitoring strategy or issuing the alarm information according to the analysis result, notifying the operation and maintenance personnel to carry out the corresponding processing, so that the all-around, multi-dimensional and intelligent safety monitoring of the electric power equipment is realized.

[0044] The above is only for the purpose of illustrating the present application, and it should be understood that the present application is not limited to the above embodiments, and various modifications in accordance with the present application are within the scope of the present application.
