[0002] A thermal power plant, also known as a thermal power plant, is a factory that uses combustibles (such as coal) as fuel to produce electricity. It converts the chemical energy of the fuel into thermal energy by heating water to generate steam when the fuel is burned. The steam pressure drives the turbine to rotate, converting the thermal energy into mechanical energy. The turbine then drives the generator to rotate, converting the mechanical energy into electrical energy. In order to improve efficiency, increase the combustion air temperature, and reduce heat loss from incomplete combustion of the fuel, an air preheater is often configured to preheat the air before entering the boiler to a certain temperature of the heating surface. It is used to improve the heat exchange performance of the boiler and reduce energy consumption.

In response to the above problems, we have launched a buffer-type power protection device based on the power generation device of a thermal power plant. Utility Model Content

Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0023] Reference Figure 1 - Figure 5 A buffer type power protection device based on a thermal power plant power generation device includes a preheater 1, both sides of the preheater 1 are symmetrically fixedly connected with mounting plates 2, a connecting frame 3 is installed between the two mounting plates 2 on the same side, and a buffer mechanism 4 is arranged on the outer side of the preheater 1. The buffer mechanism 4 includes a No. 1 buffer component, a No. 2 buffer component and a stabilizing component. The No. 1 buffer component, the No. 2 buffer component and the stabilizing component are used in conjunction with each other. The No. 1 buffer component includes a fixing plate 401, and the fixing plate 401 is symmetrically fixedly connected to the outer side of the connecting frame 3. The two The fixing plates 401 are fixedly connected with mounting rods 402, and the outer side of the mounting rods 402 is symmetrically slidably connected with buffer blocks 404. The outer sides of the two mounting rods 402 are sleeved with No. 1 springs 403. The two buffer blocks 404 are fixedly connected with No. 1 rotating blocks 405 on the side away from the preheater 1. The insides of the two No. 1 rotating blocks 405 are rotatably connected with support rods 406. The other ends of the two support rods 406 are rotatably connected with fixed blocks 407. The outer sides of the two fixed blocks 407 are fixedly connected with No. 1 protective covers 408. The No. 2 buffer assembly includes a limit plate 5, which is fixedly connected to the side of the connecting frame 3 away from the preheater 1. The outer sides of the limit plates 5 are symmetrically fixedly connected with connecting tubes 6, and the inside of the connecting tubes 6 is provided with No. 2 springs 7. The inside of the connecting tubes 6 is slidably connected with connecting rods 8. The side of the connecting rods 8 close to the No. 2 springs 7 is fixedly connected with a sliding column 9, and the other ends of the two connecting rods 8 on the same side are fixedly connected with connecting blocks 10, and the No. 2 protective cover 11 is fixedly connected between the two connecting blocks 10 on the same side. The stabilizing component includes a slide groove 12 , which is opened inside the connecting frame 3 , and a slide rod 13 is fixedly connected inside the slide groove 12 , and the slide rod 13 passes through the slider 14 and is slidably connected to the slider 14 .

[0024] In the above technical solution, considering that there is a large gap between the baffles, most of the preheater 1 is still exposed to the outside and lacks protection. The hand of the staff may accidentally pass through the baffle and touch the preheater 1, which may cause burns. In order to solve this problem, the specific operations are as follows:

[0025] Reference Figure 1 - Figure 5 In a preferred embodiment, the preheater 1 is protected by using a No. 1 protective cover 408 and a No. 2 protective cover 11 to prevent the staff from accidentally touching the outer wall of the preheater 1 and getting burned. At the same time, the No. 1 protective cover 408 and the No. 2 protective cover 11 are both mesh-shaped, so they will not affect the heat dissipation of the preheater 1. When the No. 1 protective cover 408 is squeezed, the two support rods 406 drive the two buffer blocks 404 to slide away from each other on the outside of the mounting rod 402, and the No. 1 spring 403 buffers and filters the squeezing force. If the No. 1 protective cover 408 is squeezed, the two support rods 406 drive the two buffer blocks 404 to slide away from each other on the outside of the mounting rod 402. The No. 1 spring 403 buffers and filters the squeezing force. The No. 1 protective cover 11 is squeezed, the connecting rod 8 slides inside the connecting tube 6, and the No. 2 spring 7 is squeezed, so that the No. 2 spring 7 can filter and buffer the squeezing force on the front side. The buffer mechanism 4 is provided to protect the preheater 1, avoid the staff from accidentally touching the outer wall of the preheater 1, and reduce the possibility of scalding. At the same time, the squeezing force on the preheater 1 can be filtered and buffered to avoid squeezing damage to the preheater 1. At the same time, it also reduces the loss caused by direct collision, and plays a role of buffering and protection for the preheater 1. The structure is simple and the practicability is strong.

[0026] Reference Figure 1 - Figure 5 In a preferred embodiment, the top of the preheater 1 is symmetrically fixedly connected with fixing rods 15, and the tops of the two fixing rods 15 are fixedly connected with protective plates 16. The bottom of the preheater 1 is symmetrically fixedly connected with a support seat 17. The protective plates 16 can protect the top of the preheater 1 to prevent debris from falling and damaging the preheater 1. The support seats 17 can support the preheater 1, increase the support area, and make the preheater 1 more stable.

[0027] Working principle: In actual use, the preheater 1 preheats the air before entering the boiler, and the preheater 1 itself begins to heat up. The preheater 1 is protected by the No. 1 protective cover 408 and the No. 2 protective cover 11 to prevent the staff from accidentally touching the outer wall of the preheater 1 and getting burned. At the same time, the No. 1 protective cover 408 and the No. 2 protective cover 11 are both mesh-shaped, so they will not affect the heat dissipation of the preheater 1. When the No. 1 protective cover 408 is squeezed, the two support rods 406 drive the two buffer blocks 404 to slide away from each other on the outside of the mounting rod 402, and the No. 1 spring 403 buffers and filters the squeezing force. If the No. 2 protective cover 11 is squeezed, the connecting rod 8 slides inside the connecting tube 6, and the No. 2 spring 7 is squeezed, and then the No. 2 spring 7 can filter and buffer the squeezing force on the front.

[0028] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
