[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] like Figure 1As shown, an anti-detachment device for replacing electrode wires in an electrostatic precipitator includes two mounting plates 1. An anti-detachment plate 2 is snapped onto the inner wall of the lower part of the two mounting plates 1. An anti-detachment plate 3 overlaps the upper surface of the anti-detachment plate 2. The outer walls of the left and right parts of the anti-detachment plate 3 are respectively movably sleeved with the inner walls of the two mounting plates 1. Limiting and fixing components 5 overlap the upper surfaces of the left and right parts of the anti-detachment plate 3. The outer walls of the left and right parts of the limiting and fixing components 5 are respectively fixedly installed with the inner walls of the two mounting plates 1. Protective components 4 are fixedly connected to the inner walls of the limiting holes in the middle of the anti-detachment plate 2 and the anti-detachment plate 3.

[0029] First, install and fix the two mounting plates 1 inside the electrostatic precipitator. Then, snap the anti-detachment plate 2 into the bottom of the inner wall of the two mounting plates 1. Next, neatly place the electrode wire in the limiting hole in the middle of the anti-detachment plate 2. Then, push the anti-detachment plate 3 into the inner wall of the two mounting plates 1 and move it downward so that the lower surface of the anti-detachment plate 3 overlaps with the upper surface of the anti-detachment plate 2. At this time, the electrode wire can be restricted and fixed between the anti-detachment plate 2 and the anti-detachment plate 3. The protective component 4 provides a certain degree of protection while restricting and fixing the electrode wire. Finally, the limiting and fixing component 5 restricts and fixes the anti-detachment plate 3 to the upper surface of the protective component 4, thereby ensuring the stability of the fixation and facilitating disassembly, maintenance and replacement.

[0030] like Figure 2 As shown, a rubber pad 53 is fixedly connected to the lower surface of the limiting block 52, and the lower surface of the rubber pad 53 overlaps with the upper surface of the anti-detachment plate 3.

[0031] The rubber pad 53 provides a buffering effect when the limiting block 52 presses against the anti-detachment plate 3, thus preventing collisions and providing protection.

[0032] like Figure 3 , Figure 4 As shown, the limiting and fixing assembly 5 includes two limiting blocks 52. The outer walls of the two limiting blocks 52 are slidably connected to the inner walls of the two mounting and fixing plates 1 respectively. A U-shaped tie rod 51 is fixedly connected to the upper surface of the two limiting blocks 52. The outer walls of the left and right parts of the U-shaped tie rod 51 are movably sleeved with the inner walls of the two mounting and fixing plates 1 respectively. A limiting block 54 is fixedly connected to the lower part behind the limiting blocks 52.

[0033] By pulling the U-shaped lever 51, the two limiting blocks 52 can be moved upward to the upper part of the inner wall of the mounting plate 1. At this time, the anti-detachment plate 1 2 can be pushed into the opening in the middle of the two mounting plates 1, and then pushed downward to move the anti-detachment plate 1 2 to the bottom of the inner wall of the two mounting plates 1. At this time, the electrode can be neatly placed in the limiting hole in the middle of the anti-detachment plate 1 2. Then, the anti-detachment plate 2 3 is also pushed into the inner wall of the mounting plate 1. Then, the anti-detachment plate 2 3 is moved to the upper surface of the anti-detachment plate 1 2, so that the electrode is restricted and fixed between the anti-detachment plate 1 2 and the anti-detachment plate 2 3. Finally, the U-shaped lever 51 is released, so that the two limiting blocks 52 can move downward to the upper surface of the anti-detachment plate 2 3 under the action of the two springs 56, thereby restricting and fixing the anti-detachment plate 2 3, thereby further improving the stability of the electrode and preventing it from falling off.

[0034] like Figure 5 As shown, the outer wall of the limiting block 54 is movably sleeved with the inner wall of the mounting plate 1, and a guide rod 55 is fixedly connected to the lower surface of the limiting block 54. The outer wall of the guide rod 55 is movably sleeved with the inner cavity of the mounting plate 1.

[0035] The guide rod 55 enables the limiting block 52 to move stably up and down within the cavity of the mounting plate 1, thereby achieving the function of limiting movement.

[0036] A spring 56 is fixedly connected to the top of the inner cavity of the guide rod 55. The outer wall of the spring 56 is movably sleeved with the inner wall of the guide rod 55. The lower surface of the spring 56 is fixedly connected to the bottom of the inner cavity of the mounting plate 1.

[0037] The spring 56 enables the limiting block 52 to limit and press the anti-detachment plate 3 under the protection of the rubber pad 53, thereby ensuring that the anti-detachment plate 3 and the anti-detachment plate 2 can stably limit the electrode wire and better prevent it from falling off.

[0038] like Figure 6 As shown, the protective component 4 includes an insulating outer layer 41. The opposing surfaces of the front and rear portions of the insulating outer layer 41 are respectively fixedly connected to the inner wall of the limiting hole in the middle of the anti-detachment plate 3. An arc-shaped sponge pad 42 is fixedly connected to the inner cavity of the insulating outer layer 41.

[0039] The curved sponge pad 42 provides a certain degree of flexibility between the insulating outer layer 41 and the curved elastic rubber pad 43, thus providing protection when fixing the electrode wire.

[0040] like Figure 7 As shown, an arc-shaped elastic rubber pad 43 is fixedly connected to the outer wall of the arc-shaped sponge pad 42, and the outer wall of the arc-shaped elastic rubber pad 43 is fixedly connected to the inner cavity in the middle of the insulating outer layer 41.

[0041] Through the action of the arc-shaped elastic rubber pad 43, the anti-detachment plate 1 2 and the anti-detachment plate 2 3 can securely restrict the electrode wire without damaging the outer wall of the electrode wire, thus playing a protective role.

[0042] The working principle of this utility model is as follows: First, by pulling the U-shaped pull rod 51, the two limiting pressure blocks 52 can be moved upward to the upper part of the inner wall of the mounting plate 1. At this time, the anti-detachment plate 2 can be pushed into the opening in the middle of the two mounting plates 1, and then pushed downward to move the anti-detachment plate 2 to the bottom of the inner wall of the two mounting plates 1. At this time, the electrode wire can be neatly placed in the limiting hole in the middle of the anti-detachment plate 2. Then, the anti-detachment plate 3 is similarly pushed into the inner wall of the mounting plate 1, and then the anti-detachment plate 3 is moved to the upper surface of the anti-detachment plate 2. The electrode wire is fixed between the first anti-detachment plate 2 and the second anti-detachment plate 3. The arc-shaped elastic rubber pad 43 ensures that the first anti-detachment plate 2 and the second anti-detachment plate 3 can securely restrict the electrode wire without damaging its outer wall. Finally, the U-shaped pull rod 51 is released, allowing the two limiting blocks 52 to move downward to the upper surface of the second anti-detachment plate 3 under the action of the two springs 56, thereby restricting and fixing the second anti-detachment plate 3, further improving the stability of the electrode wire and preventing it from falling off.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
