DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4A filter element for a safety filter used in a power plant comprises an upper cover 5, a tank body 1 and a filter element body 16 arranged in the tank body 1. The lower end of the tank body 1 is fixedly connected with a plurality of legs for supporting the tank body 1. The lower ends of the legs are fixedly connected with rubber pads for improving the wear resistance of the lower ends of the legs. The upper cover 5 is located directly above the tank body 1. The upper end of the tank body 1 is fixedly sleeved with a connecting ring 3 for fixing a connecting rod 4. The upper end of the connecting ring 3 is fixedly connected with a plurality of connecting rods 4 distributed in an annular shape for cooperating with a clamping block 12 to prevent the upper cover 5 from loosening. The lower end of the upper cover 5 is fixedly connected with a fixing ring 6 for supporting the mounting ring 2. The lower end of the fixing ring 6 is provided with a connecting hole corresponding to the connecting rod 4. The upper end of the connecting rod 4 slides through the connecting hole.

[0022] In this embodiment, the upper end of the fixing ring 6 is fixedly connected with a mounting ring 2 for mounting a clamping block 12. A wedge-shaped groove is provided on the side of the connecting rod 4 close to the mounting ring 2. A wedge-shaped clamping block 12 is slidably inserted on the inner side wall of the wedge-shaped groove to cooperate with the wedge-shaped groove to prevent the upper cover 5 from loosening. A groove is provided on the end of the clamping block 12 away from the lead screw 13. A ball is rollingly connected on the inner side wall of the groove to reduce the friction between the clamping block 12 and the inner side wall of the wedge-shaped groove. Part of the ball passes through the groove.

[0023] In this embodiment, an annular groove is provided on the inner side wall of the mounting ring 2, and an opening corresponding to the block 12 is provided on the inner side wall of the annular groove. One end of the block 12 passes through the wedge-shaped groove and slides into the opening. A limiting groove is provided on the inner top of the opening. A limiting block is slidably connected to the inner side wall of the limiting groove, which is used to cooperate with the limiting groove to limit the moving stroke of the block 12 and prevent the block 12 from completely escaping from the opening. The lower end of the limiting block passes through the limiting groove and is fixed to the block 12. A lead screw 13 is inserted into the end of the block 12 away from the connecting rod 4, which is used to drive the block 12 to move. The end of the lead screw 13 away from the block 12 passes through the opening and is rotatably connected to a support block 17, which is used to support the lead screw 13. The lower end of the support block 17 is fixed to the inner bottom of the annular groove.

[0024] In this embodiment, a worm wheel 14 is fixedly sleeved on the lead screw 13, which is used to drive the lead screw 13 to rotate. A worm 15 meshing with the worm wheel 14 is rotatably connected to the inner bottom of the annular groove, which is used to drive the worm wheel 14 to rotate. A connecting block is rotatably sleeved on the worm 15, one end of which is fixed to the inner side wall of the annular groove. The upper end of the worm 15 is fixedly connected to the second gear 11, which is used to drive the worm 15 to rotate.

[0025] In this embodiment, a movable ring 10 is rotatably connected to the inner top of the annular groove, which is used to drive the second scale bar to rotate. A second rack meshing with the second gear 11 is fixedly connected to the outer wall of the movable ring 10, which is used to drive the second gear 11 to rotate. The second rack and the first rack are both annular. A first rack is fixedly connected to the inner wall of the movable ring 10, which is used to drive the movable ring 10 to rotate. A first gear 9 meshing with the first rack is provided in the movable ring 10, which is used to drive the first rack to rotate. A rotating rod 8 is fixedly connected to the upper end of the first gear 9, and the upper end of the rotating rod 8 passes through the mounting ring 2. The rotating rod 8 and the mounting ring 2 are rotatably connected. A rudder-type handle 7 is fixedly connected to the upper end of the rotating rod 8, which is used to facilitate the user to rotate the rotating rod 8.

[0026] In this embodiment, the rudder handle 7 is manually rotated to drive the rotating rod 8 to rotate, and the rotating rod 8 drives the first gear 9 to rotate, and the first gear 9 drives the first rack meshing with it to rotate, and the first rack drives the movable ring 10 and the second scale to rotate, and the second scale drives the plurality of second gears 11 to rotate, and the second gear 11 drives the worm 15 to rotate, and the meshing effect of the worm 15 and the worm wheel 14 drives the lead screw 13 to rotate, and the lead screw 13 drives the block 12 to move forward and backward through the meshing effect of the thread (the forward and backward movement is determined by the forward and reverse rotation of the lead screw 13). When the block 12 moves forward, the block 12 will be inserted into the wedge-shaped groove and abut against the wedge-shaped surface in the wedge-shaped groove, thereby pushing and pressing down the mounting ring 2, pressing down the fixing ring 6 through the mounting ring 2, and pressing down the upper cover 5 through the fixing ring 6, so that the lower end of the upper cover 5 is tightly fitted with the upper end of the tank body 1, thereby preventing the upper cover 5 from loosening.

[0027] 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 within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
