a modified solution is proposed, which is different from the first embodiment, as shown in fig. 2, fig. 10 and fig. 11, a scraping mechanism 13 for scraping the surface of the filter plate 8 is fixedly arranged on the mounting disc 4, the scraping mechanism 13 includes a scraping plate 13a, a second connecting frame 13b and an electric push rod 13c, the electric push rod 13c is fixedly arranged on the mounting disc 4 through a connecting pipe, an output end of the electric push rod 13c is fixedly connected with the second connecting frame 13b, and the scraping plate 13a is fixedly arranged on the second connecting frame 13b. When the pressing conduit 6 rotates three circles along the installation disc 4, the number of the circles can be more, the setting can be performed as required, the electric push rod 13c is controlled by the controller to work, the electric push rod 13c pulls the second connecting frame 13b to move, so that the second connecting frame 13b pulls the scraper 13a to move, an avoiding gap for the second connecting frame 13b to pass through is formed in the installation disc 4, the width of the avoiding gap is smaller than the distance between the two limiting barrier strips 9, the two limiting barrier strips 9 are prevented from being simultaneously inserted into the avoiding gap, the scraper 13a scrapes the surface of the filter plate 8 sliding out of the inside of the pressing conduit 6, a large amount of flocks or scraps are prevented from being accumulated on the surface of the filter plate 8, in the scraping process of the scraper 13a along the filter plate 8, flocks and scraps on the surface of the scraper 13a can be scraped and accumulated, and the piled flocks can be sucked into the pressing conduit 6 along the gap between the filter plate 8 and the pressing conduit 6 due to increase in volume;
and an electric control mode can be adopted, the air pump connected with the air outlet pipe 2 is controlled by the controller to stop working, and the air pump can be prevented from being sucked into the pressing conduit 6.
The embodiment also discloses a method for adopting the fault monitoring device for the high-voltage power distribution cabinet, which comprises the following steps:
when needs detect the internal gas content of a plurality of cabinets, the earlier control is bled the work with the pump body that outlet duct 2 is connected, make the gas in the switch board extracted, gas will be along gas piping 1 suction, it enters into to compress tightly pipe 6 inside to pass gas guide hole 4a again, it enters into coupling hose 10 and connects hard tube 11 inside to compress tightly pipe 6 again, at last along connecting hard tube 11 entering into outlet duct 2 in, then it detects to enter into gas detection appearance again, gas after the detection will be along being pumped the switch board outside by the air pump, gas will purify through waste gas filter before taking out.
After the area corresponding to the first gas pipeline 1 is exhausted and detected, the controller controls the driving motor 3e to work, the driving motor 3e drives the gear 3d to rotate, the gear 3d drives the gear ring 3c to rotate through meshing, the gear ring 3c drives the rotating ring 3b to rotate, the rotating ring 3b rotates on the rotating seat 3a, and the rotating ring 3b drives the first connecting frame 12 and the guide carriage 5c3 to rotate together.
The first connecting frame 12 is driven to rotate by the rotating ring 3b, and the first connecting frame 12 drives the connecting hard tube 11 to rotate together.
When the guide sliding frame 5c3 rotates, as shown in fig. 4, the guide sliding frame 5c3 drives the pressing conduit 6 and the prop 5a to rotate together, so that the pressing conduit 6 is rotated and switched, and when the pressing conduit 6 is rotated and switched, the prop 5a originally attached to the flat slope 5b3 slides along the ascending slope 5b1, so that the prop 5a drives the end of the pressing conduit 6 to be far away from the mounting disc 4, and when the prop 5a moves to the topmost part of the ascending slope 5b1, the distance between the end of the pressing conduit 6 and the mounting disc 4 is at the farthest position.
While the first abutment spring 7a keeps the filter plate 8 in the height position unchanged during the movement of the end of the pressure conduit 6 away from the mounting disc 4, the filter plate 8 will slide out of the end of the pressure conduit 6 when moved to a position where the distance between the end of the pressure conduit 6 and the mounting disc 4 is at its greatest.
Due to the continuous rotation of the prop 5a, when the prop 5a slides down along the descending ramp 5b2, the end of the pressing conduit 6 gradually approaches the mounting disc 4, and finally the pressing conduit 6 covers the air guide holes 4a, so that the pressing conduit 6 is switched from one air guide hole 4a to another air guide hole 4 a.
After the pressing pipe 6 rotates three times along the mounting disc 4, the electric push rod 13c is controlled by the controller to work, the electric push rod 13c pulls the second connecting frame 13b to move, the second connecting frame 13b pulls the scraper 13a to move, and the scraper 13a scrapes the surface of the filter plate 8 sliding out of the pressing pipe 6.
