[0020] In this embodiment, connecting pipes 12 are provided at both ends of the pipeline 1 for installing the pipeline 1 on the dust removal system in the power distribution room.

[0021] In this embodiment, the filter screen 3 includes a plurality of splicing plates 31, each of which is provided with filter holes of the same position and quantity. The plurality of splicing plates 31 are spliced ​​together to form a complete circular filter screen 3. A limiting ring 32 is provided at the edge of the filter screen 3. The limiting ring 32 is fixedly mounted on the inner wall of the mounting tube 11. A damping pad is provided on the limiting ring 32. The damping pad can ensure that the filter screen 3 maintains a fixed posture when it is not driven by external force. Eight splicing plates 31 are provided, and the positions of the filter holes thereon correspond to the clearing needles 41.

[0022] In this embodiment, an adsorption sleeve 33 is provided in the filter hole, a retaining ring 34 is provided on the outer wall of the adsorption sleeve 33, a limiting retaining ring 35 is provided at the outer mouth of the adsorption sleeve 33, an elastic pad 36 is provided between the retaining ring 34 and the filter 3, and a contact is provided on the side of the adsorption sleeve 33 close to the dredging needle structure 4, the contact is used to connect to an external electrostatic generator so that the adsorption sleeve 33 carries static electricity, and when the adsorption sleeve 33 is displaced, the contact is disconnected, and when it is reset, the contact is connected. At the same time, when the elastic pad 36 is elastic, the adsorption sleeve 33 has a tendency to move toward the side of the dredging needle 41, but it is limited by the limiting retaining ring 35 so that it can be fixed in the filter hole.

[0023] In this embodiment, the unclogging needle 41 includes a rubber plug head 411, a push piece 412 and a connecting rod 413, the rubber plug head 411 is located at the head of the connecting rod 413, the push piece 412 is fixedly arranged on the connecting rod 413, the distance between the large diameter bottom surface of the rubber plug head 411 and the push piece 412 is smaller than the length of the filter hole, and a dust collecting groove is provided on the rubber plug head 411. The unclogging needle 41 is pushed by the rubber plug head 411 whose diameter matches the inner diameter of the adsorption sleeve 33, overcomes the elastic force of the elastic pad 36 and pushes the adsorption sleeve 33 outward to disconnect the contact until the friction between the rubber plug head 411 and the adsorption sleeve 33 is smaller than the elastic force of the elastic pad 36, the rubber plug head 411 starts to move relative to the inner wall of the adsorption sleeve 33, and cleans the dust on the inner wall when the contact is disconnected. The dust collecting groove has the functions of collecting dust and reducing friction at the same time.

[0024] In this embodiment, a ball is provided at the head of the boss 42, and the boss 42 and the unclogging needle 41 are respectively fixedly mounted on both sides of the fixing plate 43. The fixing plate 43 is slidably connected to the top seat plate 9 through a connecting plate. The unclogging needle 41 is inserted into the adsorption sleeve 33 through the cooperation between the boss 42 and the cam 51. A tension spring is provided between the fixing plate 43 and the cam plate 5 to help the fixing plate 43 to reset.

[0025] In this embodiment, the cam plate 5 is provided with a corrugated cam 51, and the cam plate 5 is provided with a groove 52 matching the elastic pin 71. The grooves 52 are provided with two and are arranged at an interval of 135° on the circular concave inner wall of the cam plate 5. The bottom of the elastic pin 71 is provided with an elastic member and is installed in the transmission shaft 72. The transmission shaft 72 is connected to the filter screen 3. The pressing block 81 is arranged on the baffle 8 at an interval of 90° and protrudes from the side of the baffle 8. The pressing block 81 is fan-shaped as a whole, and the inner side surface of the pressing block 81 is a gradually changing curved surface from far to near the transmission shaft 72. When the cam plate 5 rotates, the rotation of the groove 52 causes the elastic pin 71 to be inserted into the groove 52 under the elastic force of the elastic member 7, so that the transmission shaft 72 rotates with the cam plate 5, and The filter screen 3 is driven to rotate. At the same time, due to the effect of the pressure block 81 on the elastic pin 71, the elastic pin 71 will be pressed back into the transmission shaft 72, so that the elastic pin 71 is disengaged from the groove 52, and the transmission shaft 72 no longer rotates with it. Because the fan-shaped angle set by the pressure block 81 is 45°, the filter screen 3 is rotated 45°. With the eight blocks evenly arranged as a whole, the entire splicing plate 31 can be rotated. At the same time, because two grooves 52 are set and a corresponding 135° angle is set, when the previous groove 52 follows the elastic pin 71 to rotate to the tail of the pressure block 81, the latter groove 52 will rotate to the head of another pressure block 81. When the elastic pin 71 rotates to the latter groove 52, the transmission shaft 72 is driven to rotate again, so that the filter screen 3 rotates the entire splicing plate 31 again.

[0026] In this embodiment, the top seat plate 9 is fixedly mounted on the top of the inner wall of the mounting tube 11 .

[0027] Working principle: After the entire equipment is correctly installed, when it is necessary to clean the dust adsorbed on the filter 3, the motor 6 is set to drive the cam plate 5 to rotate, so that the cam 51 can push the unblocking needle 41 to clean the adsorption sleeve 33. At the same time, the rotating cam plate 5 can also drive the filter 3 to rotate, so that the unblocking needle 41 can clean the holes on different splicing plates 3.
