Description

Technical Field

[0001] The present invention relates to the technical field of power station operation and maintenance, and in particular to monitoring equipment with a warning structure for power station operation and maintenance. Background Art

[0002] The task of power station operation and maintenance is to operate and maintain the power equipment of the power grid system. It is an important part of the production of power grid enterprises. Because the normal operation of each power equipment requires continuous operation, maintenance and overhaul, the operation and maintenance of the power station is of vital importance. The operation and maintenance of the power station specifically includes the installation of electrical equipment, commissioning management, operation overhaul and maintenance management, regular training of power station technicians and electrical knowledge training for operators, responsible for the protection and abnormal resolution of switches, transformers and instruments in the power station, and annual safety production inspection of the power station to ensure the normal production and operation of the power station. These processes involve many abnormal inspections, elimination and overhauls during the operation of the power station, which require the use of some monitoring equipment to assist in completion.

[0003] However, most of the existing power station operation and maintenance monitoring equipment are fixed-point monitoring or partial area monitoring, and cannot conduct large-scale patrol monitoring of the power station; and many monitoring equipment need to be manually cleaned of dust on their monitoring windows after being used for a period of time, which is time-consuming and laborious; at the same time, the existing monitoring equipment does not have the function of simultaneously monitoring smoke and temperature changes, and cannot monitor fires or abnormal smoke in power stations; in addition, the existing monitoring equipment does not have the function of conducting targeted monitoring of abnormal areas when abnormal situations occur, making it impossible for emergency repair personnel to determine the cause and treatment plan of the abnormality through the monitoring equipment; in particular, most of the power station operation and maintenance monitoring equipment does not have its own protection structure. Once affected by external environmental factors (such as temperature, open flames, smoke, humidity, etc.), the monitoring equipment quickly loses its observation and evidence collection function, and cannot well meet people's demand for the use of modern power station operation and maintenance monitoring equipment.

[0039] In this embodiment, Figure 1 , Figure 3 and Figure 4 As shown, the top of the rotating pan-tilt platform 2 is fixedly connected to a column shaft 201, the lower part of the outer wall of the rotating pan-tilt platform 2 is fixedly connected to a rotating tooth 202, one side of the surface of the rotating tooth 202 is meshed with one side of the surface of a power gear 203, the middle part of the surface of the power gear 203 is fixedly connected to a rotating motor 204, and the bottom of the rotating pan-tilt platform 2 is movably connected to a bottom bearing 205.

This structure facilitates the reciprocating rotation of the rotating pan-tilt platform 2 under the action of the rotating motor 204, so as to monitor a larger area in the operation and maintenance of the power station.

[0040] In this embodiment, Figure 2 , Figure 3 and Figure 4 As shown, a servo motor 301 is fixedly connected to one end of the top of the patrol camera 3, a cleaning brush 302 is fixedly connected to one end of the servo motor 301, a protective glass 303 is fixedly connected to the front of the patrol camera 3, and a pitch axis seat 304 is fixedly connected to the bottom of the patrol camera 3.

This structure can be reciprocated regularly by the servo motor 301, so that the cleaning brush 302 regularly cleans the surface of the protective glass 303 to ensure that the patrol camera 3 always has a clear monitoring window.

[0041] In this embodiment, Figure 1 . Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, three sides of the top of the main cabinet 1 are provided with penetrating embedding grooves 106, and the size of the fireproof glass cover 5 is consistent with the size of the embedding grooves 106 provided at the top and bottom of the main cabinet 1. At the same time, the fireproof glass cover 5 forms a movable structure with the main cabinet 1 through the embedding grooves 106. When the sensor 102 receives an abnormal alarm, this structure can retract the limit block 105 to allow the fireproof glass cover 5 to slide along the embedding grooves 106, thereby isolating the core device in the monitoring equipment from the external environment.

[0042] In this embodiment, Figure 1 and Figure 2 As shown, a movable structure is formed between the main cabinet 1 and the detection box 107, and an openable structure is formed between the emergency room 4 and the inspection door 401. This structure can realize daily inspection and maintenance of the monitoring equipment by quickly disassembling the detection box 107 or opening the inspection door 401.

[0043] In this embodiment, Figure 2 , Figure 3 and Figure 5 As shown, the size of the zoom camera 402 is consistent with the size of the reserved hole 101. This structure can ensure that the zoom camera 402 can smoothly pass through the reserved hole 101 and enter the interior of the main cabinet 1 to perform targeted monitoring and observation.

[0044] In this embodiment, Figure 2 , Figure 3 and Figure 5As shown, the lifting motor 407 forms an integrated structure with the top of the main cabinet 1 through the supporting platform 408. This structure can ensure that the lifting motor 407 maintains a stable operating state and will not affect the monitoring quality of the zoom camera 402 due to shaking during starting or stopping.

[0045] In this embodiment, Figure 2 , Figure 3 and Figure 5 As shown, the central axis of the driving gear 405 and the central axis of the balancing auxiliary gear 406 are parallel to each other, and the driving gear 405 and the balancing auxiliary gear 406 form a symmetrical structure with the central axis of the spur gear lifting rod 404. This structure can keep the rising and falling of the spur gear lifting rod 404 in a balanced and stable state, so that the zoom camera 402 can smoothly pass through the reserved hole 101 for lifting and lowering.

[0046] In this embodiment, Figure 2 , Figure 3 and Figure 5 As shown, the zoom camera 402 forms a lifting structure with the top of the main cabinet 1 through a hanging pan-tilt head 403, a straight-tooth lifting rod 404, a driving gear 405, a balance auxiliary gear 406, a lifting motor 407, and this structure can facilitate the zoom camera 402 to descend and conduct targeted centralized observation and monitoring of the abnormal area when an abnormal situation occurs.

[0047] In summary, the monitoring device with a warning structure for power station operation and maintenance is installed in areas where dangerous situations or abnormal situations are prone to occur during the operation and maintenance of the power station. The rotating pan-tilt head 2 with a rotating gear 202 fixed on the surface is rotated by rotating the rotating motor 204 and the power gear 203 at one end thereof. The rotating motor 204 here is a servo-programmed motor that can rotate forward and reverse in different time periods. Therefore, the patrol camera 3 can be driven to rotate back and forth through the column shaft 201, which is convenient for monitoring a larger range of the power station. At the same time, the monitoring angle of the patrol camera 3 can be adjusted through the pitch shaft seat 304, and the cleaning brush 302 is controlled by the servo motor 301 to periodically scrape the dust on the surface of the protective glass 303, so that the patrol camera 3 always maintains a relatively clear monitoring window; at the same time, through the monitoring of the temperature sensor 108 and the smoke sensor 109 inside the detection box 107, the temperature change and the smoke content change in the key area can be monitored and discovered. If an abnormal situation is detected, the temperature sensor 108 or the smoke sensor 109 will trigger the warning light 6 to light up, and automatically turn on the lifting motor. The machine 407 rotates the driving gear 405 to drive the straight-tooth lifting rod 404 to move downward, lowering the zoom camera 402, and turning the zoom camera 402 to the direction of the detected abnormal area through the hanging pan / tilt 403, and the changes in the abnormal area are clearly captured by the automatic zoom camera, so that the maintenance personnel can get the fastest and most accurate feedback of the abnormal situation; during the process, the sensor 102 will use the telescopic spring 104 to retract the limit block 105, and the fireproof glass cover 5 will lose the limiting effect of the limit block 105, and can slide along the embedded groove 106 It falls down, isolating the core area of ​​the monitoring equipment, namely the patrol camera 3 and the zoom camera 402, from the external environment, maximally protecting the normal use functions of the patrol camera 3 and the zoom camera 402, so as to continue to monitor abnormal conditions, record abnormal changes and provide an observation window for maintenance personnel to continue working; the monitoring equipment sets the detection box 107 and the main cabinet 1 as active structures, and sets an openable and closable maintenance door 401 on the back of the emergency room 4, which can facilitate the daily maintenance and maintenance of the monitoring equipment and ensure the long-term normal operation of the monitoring equipment.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
