Description

Technical Field

[0001] The invention belongs to the technical field of power distribution equipment, in particular to an automatic detection device for power distribution equipment. Background Art

[0002] Distribution equipment is a general term for high-voltage distribution cabinets, generators, transformers, power lines, circuit breakers, low-voltage switch cabinets, distribution boards, switch boxes, control boxes and other equipment in the power system. The electrical components in the distribution equipment will generate heat when working. If the heat is not dissipated in time, it will cause a fire. Detection devices are needed to perform real-time detection on them to ensure the stable operation of the electrical equipment in the distribution cabinet and eliminate safety hazards.

[0003] Publication number CN115120916A discloses an automated detection device for power distribution equipment, which detects the inside of the equipment in real time through an alarm device, a temperature sensor, a humidity sensor and a smoke sensor. When one of the temperature, humidity and smoke concentration inside the power distribution equipment reaches a set value, the sensor will transmit the signal to the processor on the main board. After processing, the processor will make the buzzer sound an alarm and make the fire extinguishing device and the smoke exhaust device work. When the humidity, temperature or smoke concentration is lower than the set value, the processor will stop the alarm, and the fire extinguishing device and the smoke exhaust device will stop.

Each hollow box 33 cooperates with the temperature sensor 3, the humidity sensor 31 and the smoke sensor 32; the outer wall of the hollow box 33 is fixedly connected with a first gear 34, and the three first gears 34 are meshed with each other; a first motor 36 is fixedly connected to the inside of one end of the ash box 23; the output shaft of the first motor 36 is fixedly connected with a second gear 35, and a first gear 34 is provided at the lower part of the hollow box 33, and the second gear 35 is meshed with the adjacent first gear 34; a driving mechanism is provided on one side of the ash box 23; a heat dissipation mechanism is provided on the rear side wall of the power distribution cabinet, and the heat dissipation mechanism includes a heat dissipation fan 62, a fin 66, a refrigerator 68 and a water tank 69; In the prior art, temperature sensors 3, humidity sensors 31 and smoke sensors 32 are used to realize the function of detecting power distribution equipment. However, power distribution equipment is mostly set up on the roadside. Dust flying on the roadside enters the power distribution equipment, which is not only easy to cover the electrical components, affecting heat dissipation, but also causing heat accumulation in the power distribution equipment. The temperature sensor 3, humidity sensor 31 and smoke sensor 32 detect through infrared rays. Infrared rays absorb dust in the power distribution equipment.

[0021] During dust cleaning, the route is set through the PLC controller to drive the first electric push rod 21 to move the dust box 23 to the bottom of the temperature sensor 3, and then drive the second electric push rod 22 to move the dust box 23 upward to the outer wall of the temperature sensor 3 for quick dust cleaning; when not working, the first electric push rod 21 and the second electric push rod 22 are moved in the opposite direction to retract the dust box 23 and the hollow box 33 without hindering the detection of the distribution cabinet body 1.

[0022] like Figure 7 As shown, a cross rod 37 is fixedly connected to the top of the second gear 35; a connecting rod 38 is rotatably connected to the top inner wall of the distribution cabinet body 1 through a bearing; a slot 39 is opened at the bottom of the connecting rod 38; the cross rod 37 is inserted in the slot 39; the top of the connecting rod 38 is fixedly connected to the first rotating wheel 4; two reciprocating screw rods 43 are rotatably connected to the two ends of the distribution cabinet body 1 through bearings; the bottom ends of the reciprocating screw rods 43 are fixedly connected to the third rotating wheel 44, and a second belt 45 is sleeved between the two third rotating wheels 44; the top end of the reciprocating screw rod 43 close to the second gear 35 is fixedly connected to the second rotating wheel 42, and a first belt 41 is sleeved between the second rotating wheel 42 and the first rotating wheel 4; a lifting plate 46 is threadedly connected to the two reciprocating screw rods 43; a dust collection component is provided on one side of the lifting plate 46.

[0023] When the cross rod 37 and the connecting rod 38 are in use, by driving the second electric push rod 22 to move the dust box 23 upward to the outer wall of the temperature sensor 3, since the route is fixed, the cross rod 37 is just inserted into the slot 39 and cooperates with the connecting rod 38. The connecting rod 38 is driven to rotate by the cross rod 37, and the work of the cleaning component and the dust collection component are linked together to clean the various components in the distribution cabinet body 1.

[0024] like Figure 3 and Figure 5 As shown, an air supply pipe 5 is fixedly connected to the side wall of the lifting plate 46 away from the cabinet door 11; a plurality of dust hoods 51 are connected and fixedly connected to the air supply pipe 5, and the length of the dust hoods 51 matches the power distribution cabinet body 1; one end of the air supply pipe 5 is connected and fixedly connected to a dust collection pipe 52; a collection box 53 is fixedly connected to the outer wall of the power distribution cabinet body 1; one end of the dust collection pipe 52 extends into the collection box 53; a fan 54 is fixedly connected to the side wall of the collection box 53 via a mounting plate; the fan 54 is connected and fixedly connected to the collection box 53 via a ventilation pipe.

[0025] like Figure 4 As shown, a ventilation plate 6 is fixedly connected to the rear side wall of the distribution cabinet body 1, and a protective cover 61 is fixedly connected to the rear side wall of the distribution cabinet body 1, and the protective cover 61 cooperates with the ventilation plate 6; a dustproof plate 63 is fixedly connected to the outer side wall of the protective cover 61; and an air outlet plate 64 is fixedly connected inside the protective cover 61.

[0026] The ventilation plate 6 and the air outlet plate 64 provided by the present invention are convenient for dissipating the heat in the power distribution cabinet body 1 when in use, and the dustproof plate 63 is provided to reduce the entry of external dust into the power distribution cabinet body 1.

[0027] like Figure 4 As shown, a second motor 611 is fixedly connected to the dustproof plate 63, an output shaft of the second motor 611 extends to the air outlet plate 64, a cooling fan 62 is fixedly connected to the output shaft of the second motor 611; a cleaning brush 65 is fixedly connected to the output shaft of the second motor 611, and the cleaning brush 65 is in contact with the dustproof plate 63.

[0028] When the cleaning brush 65 provided by the present invention is in use, the output shaft of the second motor 611 drives the cleaning brush 65 to rotate. The cleaning brush 65 rubs against the dustproof plate 63 during rotation to wipe off the dust on the dustproof plate 63, thereby preventing dust from clogging the dustproof plate 63 and affecting heat dissipation.

[0029] like Fig. 9 As shown, the bottom of the dust cover is fixedly connected with a refrigerator 68, a circulating water pump 610 and a water tank 69 in sequence, and one end of a hollow heating tube 67 is connected and fixedly connected to the water tank 69; the other end of the hollow heating tube 67 is connected and fixedly connected to the refrigerator 68, and the hollow heating tube 67 is arranged in a ring shape, and the two ends of the circulating water pump 610 are respectively connected to the refrigerator 68 and the water tank 69 through a hose.

[0030] like Fig. 9 As shown, a plurality of fins 66 are fixedly connected to the inner wall of the dust cover, and the hollow heating tube 67 is inserted into the plurality of fins 66 .

[0031] When the fins 66 provided by the present invention are in use, the fins 66 expand the heat contact area and quickly dissipate the heat in the hollow heating tube 67 and the protective cover 61.

[0032] like Fig. 9 As shown, the hollow heating tube 67 includes a metal layer and an insulating layer. The insulating layer is arranged inside the metal layer, and the insulating layer is set to be hollow.

[0033] When the hollow heating tube 67 provided by the present invention is in use, the metal layer of the hollow heating tube 67 facilitates the heating of the hollow heating tube 67. When the humidity in the distribution cabinet body 1 is high due to rain, the heating of the hollow heating tube 67 is controlled by the humidity sensor 31. At this time, the cooling fan 62 is used to blow hot air into the distribution cabinet body 1 for rapid drying. The setting of the insulation layer prevents the internal cold water from affecting the use of the heating tube. When heat dissipation is required, the hollow heating tube 67 is powered off and can be used for heat dissipation after cold water circulation.

[0034] Working principle: The PLC controller periodically controls the driving mechanism to move the ash box 23 according to the set route. The ash box 23 drives the hollow box 33 to move to the outside of the temperature sensor 3, the humidity sensor 31 and the smoke sensor 32, and surrounds the temperature sensor 3, the humidity sensor 31 and the smoke sensor 32. Then the first motor 36 is turned on, and the second gear 35 is driven to rotate by the output shaft of the first motor 36, and the adjacent first gear 34 is driven to rotate by the second gear 35, and the other two first gears 34 are driven to rotate by the first gear 34, and the hollow box 33 is driven to rotate by the first gear 34, and the soft brush is driven to rotate by the hollow box 33, and the dust on the outside of the temperature sensor 3, the humidity sensor 31 and the smoke sensor 32 is cleaned by the soft brush, and the dust finally enters the ash box 23 through the hollow box 33 to collect the dust, so as to realize the function of cleaning the temperature sensor 3, the humidity sensor 31 and the smoke sensor 32; When the connecting rod 38 is driven to rotate by the cross rod 37, the connecting rod 38 drives the first rotating wheel 4 to rotate, the first rotating wheel 4 drives the first belt 41 to rotate, the first belt 41 drives the second rotating wheel 42 to rotate, the second rotating wheel 42 drives the connected reciprocating screw 43 and the third rotating wheel 44 to rotate, the second belt 45 is driven to rotate by the third rotating wheel 44, and the other third rotating wheel 44 and the reciprocating screw 43 are driven to rotate by the second belt 45, so that the two reciprocating screws 43 rotate synchronously, the lifting plate 46 is driven to reciprocate up and down by the reciprocating screw 43, the two reciprocating screws 43 maintain the stability of the lifting plate 46, and the dust collection assembly is driven to reciprocate up and down by the lifting plate 46, and the fan 54 is turned on. The wind force generated by the fan 54 generates negative pressure in the collection box 53, and the dust in the distribution cabinet body 1 is sucked into the collection box 53 through the dust cover 51, the air pipe 5 and the dust collection pipe 52 according to the negative pressure adsorption, so as to achieve a comprehensive cleaning of the inside of the distribution cabinet body 1; The temperature sensor 3 monitors the heat of the distribution cabinet body 1, turns on the second motor 611, and drives the cooling fan 62 to rotate through the output shaft of the second motor 611, and blows wind into the distribution cabinet body 1 through the cooling fan 62. During the heat dissipation process, under the action of the circulating water pump 610, the water in the water tank 69 enters through the hollow heating tube 67, and is finally cooled by the refrigerator 68 and enters the water tank 69 again, thereby realizing water cooling and circulation. At this time, the cold air of the cooling water is blown into the distribution cabinet body 1 through the cooling fan 62, which accelerates the heat dissipation of the distribution cabinet body 1 and extends the service life of the distribution cabinet body 1.

[0035] The humidity sensor 31 monitors the humidity in the power distribution cabinet body 1. When the humidity needs to be reduced, the hollow heating tube 67 is heated. At this time, in conjunction with the cooling fan 62, hot air is blown into the power distribution cabinet body 1 for rapid drying.

[0036] The smoke sensor 32 monitors the smoke inside and outside the power distribution cabinet body 1, and promptly alarms and performs power-off protection, thereby eliminating the heat source and reducing the possibility of fire.
