Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinet detection, and in particular to an abnormality detection device for a power distribution cabinet. Background Art

[0002] The power safety of the distribution cabinet is an issue that needs to be focused on in the field of power distribution. When an abnormal condition occurs in the distribution cabinet, a higher temperature is often generated in the distribution cabinet than in normal use. In the prior art, a temperature detection device is set in the distribution cabinet to detect the temperature inside the distribution cabinet. By judging the deviation between the internal temperature of the distribution cabinet and the set value, it is judged whether the distribution cabinet is abnormal.

[0003] There are many reasons for the temperature rise inside the power distribution cabinet. It is difficult to determine the cause of the fault only by the overall temperature inside the power distribution cabinet, and it is impossible to know which electronic components in the power distribution cabinet have abnormalities. This makes it impossible for the staff to further judge the abnormal situation in the first time, thus affecting the maintenance efficiency. Therefore, it is necessary to perform separate temperature detection on each electronic component inside the power distribution cabinet. However, when performing separate temperature detection on each electronic component, multiple temperature sensors need to be arranged for detection. Since this detection method uses multiple temperature sensors, it is not suitable for large-scale use;

[0004] Therefore, it is necessary to invent a distribution cabinet abnormality detection device. Summary of the invention

[0005] To this end, the present invention provides an abnormality detection device for a distribution cabinet. By setting two groups of circular tracks, the monitoring device as a whole can run on the circular tracks. At the same time, the second temperature sensor and the first temperature sensor on the monitoring device respectively detect the temperature of each electrical appliance inside the distribution cabinet. At the same time, the monitoring camera on the monitoring device detects the usage status of the electrical appliances to prevent electrical hazards inside the electrical appliances, so as to solve the problems of low working efficiency and large amount of detection elements used in the existing distribution cabinet detection device.

The tops of the two groups of driving pulleys 115 are fixedly installed with a first straight gear 116. A servo motor 117 is fixedly installed at the bottom of the L-shaped base plate 111 on either side. The output shaft of the servo motor 117 rotates through the L-shaped base plate 111 and is fixedly connected to the middle of the driving pulley 115.

[0027] The other sides of the two groups of L-shaped base plates 111 are both rotatably connected with driven pulleys 118, and the L-shaped base plates 111 provide support for the driven pulleys 118. The bottoms of the two groups of driven pulleys 118 are provided with driving wheels 119, and the middle parts of the two groups of driving wheels 119 are fixedly installed with fixed columns 120. The two groups of fixed columns 120 rotate and penetrate the L-shaped base plate 111, and the driving wheel 119 is connected with the driven pulley 118 through the fixed columns 120, so as to ensure that when the driven pulley 118 rotates, the driving wheel 119 can be driven to rotate, and the driven pulley 118 fixedly penetrates the top of the L-shaped base plate 111, and an elastic belt 121 is engaged between the driving pulley 115 and the driven pulley 118 for transmission.

An annular slot 144 is opened in the middle of the wheel body of the two groups of universal wheels 143. By arranging the annular slot 144 on the universal wheel 143, the annular slot 144 is engaged with the two groups of annular tracks 220, so that the monitoring device 100 can operate.

[0030] Furthermore, the monitoring component 130 includes a mounting shell 131, the bottom of the mounting shell 131 is fixedly connected to the upper surfaces of the two groups of connecting plates 141, the two groups of connecting plates 141 provide mounting support for the mounting shell 131, and a monitoring camera 132 and a first temperature sensor 133 are fixedly installed on the top of the mounting shell 131. The monitoring camera 132 can monitor the various electrical appliances inside the distribution cabinet in real time, and the first temperature sensor 133 can issue a temperature warning to the electrical appliances on the track of the circular track 220. Two groups of battery mounting boxes 135 are fixedly installed on the rear end side wall of the mounting shell 131, and the battery mounting boxes 135 provide an installation position for the battery 134. The inner walls of the two groups of battery mounting boxes 135 are fixedly installed with batteries 134, and the batteries 134 can provide the monitoring camera 132, the first temperature sensor 133 and the second temperature sensor.

The two groups of second spur gears 137 are respectively meshed with the two groups of first spur gears 116. Specifically, when the temperature of the electrical appliances in the distribution cabinet is high, when the monitoring device 100 operates around a certain high-temperature electrical appliance, the first temperature sensor 133 located on the mounting shell 131 sends a signal to remind relevant technical personnel. When the temperatures of multiple electrical appliances are abnormal, the overall temperature in the distribution cabinet rises. At this time, the second temperature sensor 170 on the second curved plate 160 located in the middle of the distribution cabinet rotating cover 210 reaches the alarm temperature, thereby reminding relevant technical personnel to perform maintenance.

[0031] Furthermore, a distribution cabinet rotating cover 210 is rotatably connected to one side of the distribution cabinet 200, and two sets of annular tracks 220 are arranged inside the distribution cabinet rotating cover 210.

Specifically, the universal wheels 143 are connected to the two groups of annular tracks 220 through the annular slots 144 above. When the servo motor 117 is running, the two groups of driving wheels 119 drive the two groups of universal wheels 143 to run, thereby causing the entire monitoring device 100 to move.

[0032] The use process of the present invention is as follows: when the electrical appliances inside the power distribution cabinet are working, by turning on the servo motor 117, the output shaft of the servo motor 117 drives the driving pulley 115 to rotate, so that the first spur gear 116 on the top of the driving pulley 115 rotates, so that the first spur gear 116 and the second spur gear 137 are meshed, and under the action of the rotating shaft 136, the first spur gear 116 and the second spur gear 137 on the other side are also meshed, so that the driving pulley 115 and the first spur gear 116 on the other side are also rotated synchronously, and under the action of the elastic belt 121, the two sets of driving pulleys 115 both drive the driven pulleys 118 to rotate, and under the action of the fixed column 120, the two sets of driven pulleys 118 both drive the driving wheel 119 to rotate, and at the same time the universal wheel 1 43 is connected with the two sets of annular tracks 220 through the annular snap seam 144 above, so that the two sets of driving wheels 119 drive the two sets of universal wheels 143 to operate, thereby causing the entire monitoring device 100 to move. At the same time, the monitoring camera 132 on the mounting shell 131 can monitor the entire electrical appliances in the distribution cabinet. When the temperature of the electrical appliances in the distribution cabinet is high, when the monitoring device 100 operates around a certain high-temperature electrical appliance, the first temperature sensor 133 located on the mounting shell 131 sends a signal to remind relevant technical personnel. When the temperatures of multiple electrical appliances are abnormal, the overall temperature in the distribution cabinet rises. At this time, the second temperature sensor 170 on the second curved plate 160 located in the middle of the distribution cabinet rotating cover 210 reaches the alarm temperature, thereby reminding relevant technical personnel to perform maintenance.
