Technical Field

[0001] The utility model relates to the technical field of wet electrostatic precipitators, and specifically relates to an installation mechanism for a cathode suspension rod of a wet electrostatic precipitator. Background Technique

[0002] After desulfurization in coal-fired power plants, the cathode system of the wet honeycomb electrostatic precipitator is a suspension structure. It is necessary to use suspension rods to suspend the weight of the entire cathode system, and the suspension rods have to bear the weight of the entire cathode system.

[0003] The existing cathode suspension rod of the wet electrostatic precipitator is a cylinder without a base, which cannot meet the requirement of using H-shaped steel for the cathode H-shaped girder, resulting in difficult construction, inconvenient installation, and the problem that the cathode H-shaped girder cannot be installed.

[0004] In view of the above problems, the utility model provides an installation mechanism for a cathode suspension rod of a wet electrostatic precipitator. Content of the Utility Model

[0005] The purpose of the utility model is to provide an installation mechanism for a cathode suspension rod of a wet electrostatic precipitator, which can quickly install the suspension rod and the cathode H-shaped girder with each other, with simple operation, high efficiency and good stability, thus solving the problems in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An installation mechanism for a cathode suspension rod of a wet electrostatic precipitator, including a cathode H-shaped girder and a suspension rod. A central column is fixedly arranged at the bottom end of the suspension rod, and a clamping block is fixedly arranged at the bottom end of the central column. The clamping block is clamped in the middle of the upper end of the cathode H-shaped girder. A support plate is fixedly arranged on the outer side of the central column. Sliders are symmetrically arranged inside both ends of the support plate. A connecting rod is fixedly arranged on the side of the slider. An insertion plate is fixedly arranged at the end of the connecting rod far from the slider. A first spring is wrapped around the outer side of the connecting rod. Rectangular boxes that are symmetrical to each other are fixedly arranged on both sides of the upper end of the cathode H-shaped girder. An L-shaped plate is fixedly arranged at the upper end of the slider. A column is fixedly arranged at the end of the L-shaped plate far from the slider. A circular ring is rotatably arranged on the outer side of the central column. Arc-shaped grooves are symmetrically opened on both sides inside the circular ring. The column is in contact connection with the inner side of the arc-shaped groove.

[0007] Further, a clamping groove is opened in the middle of the upper end of the cathode H-shaped girder, and the clamping block is clamped with the inner side of the clamping groove and they are of matching size.

[0008] Further, rectangular grooves are symmetrically opened inside both ends of the support plate. The slider is slidably connected to the inner side of the rectangular groove. The connecting rod is slidably connected to the side wall of the rectangular groove. Both ends of the first spring are tightly connected between the slider and the side wall of the rectangular groove.

The column 13 is in contact connection with the inner side of the arc-shaped groove 15.

[0022] Specifically, when the suspension rod 21 and the cathode H-shaped girder 1 are assembled, first rotate the ring 14. Through the cooperation connection between the column 13 and the inner side of the arc-shaped groove 15, the sliders 7 at both ends are driven by the L-shaped plate 12 to move synchronously towards each other, thereby driving the plug plates 9 to move synchronously towards each other, and the first spring 10 is stretched. Then, the clamping block 3 is clamped in the middle of the upper end of the cathode H-shaped girder 1. Next, release the ring 14. Under the pulling of the first spring 10 when it restores deformation, the sliders 7 drive the plug plates 9 to move synchronously away from each other, and the plug plates 9 are inserted into the rectangular boxes 11. At this time, the suspension rod 21 and the cathode H-shaped girder 1 are installed with each other. The purpose of such a design is that the suspension rod 21 and the cathode H-shaped girder 1 can be quickly installed with each other, the operation is simple, the efficiency is high, and the stability is good.

[0023] Furthermore, as Figures 1-3 shown, the following preferred technical solutions are provided:

[0024] A clamping groove 2 is opened in the middle of the upper end of the cathode H-shaped girder 1. The clamping block 3 is mutually clamped with the inner side of the clamping groove 2 and they are of matching sizes. The purpose of such a design is to initially position the suspension rod 21 and facilitate its subsequent fixation.

[0025] Furthermore, as Figures 1-4 shown, the following preferred technical solutions are provided:

[0026] Rectangular grooves 6 are symmetrically formed inside both ends of the support plate 5. The slider 7 is slidably connected to the inner side of the rectangular groove 6. The connecting rod 8 is slidably connected to the side wall of the rectangular groove 6. Both ends of the first spring 10 are firmly connected between the slider 7 and the side wall of the rectangular groove 6. The first spring 10 drives the plug board 9 to engage with the inner side of the rectangular box 11. The purpose of this design is to ensure that the slider 7 drives the plug board 9 to reciprocate linearly, and further fix the suspension rod 21 by engaging with the rectangular box 11.

[0027] Furthermore, as Figure 3 shown, the following preferred technical solution is provided:

[0028] A circular ring 14 is rotatably connected to the outside of the central column 4 through a bearing. The purpose of this design is to ensure that the circular ring 14 can rotate, and drive the slider 7 to move through the rotation of the circular ring 14.

[0030] A fixing plate 16 is fixedly provided at the upper end of the circular ring 14. A limiting column 17 is slidably connected inside the fixing plate 16. One end of the limiting column 17 is fixedly connected with a handle 18. A second spring 19 is firmly connected between the handle 18 and the fixing plate 16. A number of uniformly distributed limiting holes 20 are formed at the upper end outside the central column 4. The second spring 19 drives one end of the limiting column 17 to engage with the inner side of the limiting hole 20.

[0032] When the clamping block 3 engages with the cathode H-shaped girder 1, the plug board 9 is aligned with the rectangular box 11. The purpose of this design is to ensure the rationality of the structure.

[0033] In summary: When assembling the suspension rod 21 and the cathode H-shaped girder 1, first rotate the circular ring 14. Through the cooperation between the upright column 13 and the inner side of the arc-shaped groove 15, drive the sliders 7 at both ends to move synchronously towards each other through the L-shaped plate 12, thereby driving the plug boards 9 to move synchronously towards each other, and the first spring 10 is stretched. Then, clamp the clamping block 3 on the upper middle part of the cathode H-shaped girder 1. Next, release the circular ring 14. Under the pulling of the first spring 10 when it resumes deformation, the slider 7 drives the plug board 9 to move synchronously away from each other, and the plug board 9 is inserted into the rectangular box 11. At this time, the suspension rod 21 and the cathode H-shaped girder 1 are installed with each other. The purpose of this design is that the suspension rod 21 and the cathode H-shaped girder 1 can be quickly installed with each other, with simple operation, high efficiency, and good stability.
