Description

Technical Field

[0001] This utility model relates to the field of safety protection equipment technology, and in particular to a safety protection device for power plant personnel. Background Technology

[0002] During the boiler combustion power generation process in power plants, a large amount of slag is generated, which needs to be discharged from the boiler. However, areas such as the slag discharge port, the connection of the scraper conveyor, and the slag bin inlet are prone to blockage due to slag agglomeration and metal debris. At this time, manual intervention is required for cleaning, which requires the use of tools such as shovels and crowbars. Due to the high temperature of the slag, it is necessary to protect the workers.

[0003] Power plant personnel wear protective clothing to prevent burns when cleaning slag. However, these protective suits are bulky, inconvenient to operate, and not breathable, which causes workers to consume physical strength more quickly, thus affecting the efficiency of slag cleaning. Therefore, we provide a safety protection device for power plant personnel. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] As attached Figure 1 To be continued Figure 4 As shown: A safety protection device for power plant personnel includes a shield 1. The top of the shield 1 is arc-shaped, which can isolate a safe working environment for the staff. At the same time, the arc shape at the top can effectively block slag. A viewing window 2 is embedded in the front of the shield 1. The viewing window 2 is made of explosion-proof material. The viewing window 2 can be used to check the slag blockage, which is convenient for the staff to clean the slag later. The explosion-proof material is used to prevent the viewing window 2 from cracking. A set of support legs 4 are fixedly connected to both the front and back of the shield 1. The bottom of each support leg 4 is provided with anti-slip texture, which can provide stable support for the shield 1.

[0025] The front of the baffle plate 1 is provided with a cleaning component 3 for slag treatment. The cleaning component 3 includes a through groove 301 on the front of the baffle plate 1. An installation plate 302 is provided inside the through groove 301. A ball 303 is rotatably connected to the installation plate 302. A through groove 312 is provided inside the ball 303. A cleaning rod 304 is slidably connected to the inner wall of the through groove 312. One end of the cleaning rod 304 is conical. By holding the end of the cleaning rod 304, the slag blocking the slag in the slag discharge port can be cleared. When it is necessary to adjust the cleaning angle, the cleaning rod 304 can be directly deflected. The ball 303 will rotate flexibly on the installation plate 302, which can treat the slag blockage area without dead angles. It saves time and effort and also has a protective effect, further ensuring the cleaning effect of slag.

[0026] A retaining ring 309 is fixedly connected to the outer surface of the cleaning rod 304. The retaining ring 309 is located in front of the ball 303. The retaining ring 309 can limit the cleaning rod 304 and prevent it from sliding out of the through groove 312. A protective sleeve 310 is fixedly connected to the outer surface of the cleaning rod 304. The protective sleeve 310 is made of heat-insulating material and can protect the hands of the staff to prevent burns. An annular elastic pad 311 is fixedly connected to the inner wall of the through groove 312. The inner side of the annular elastic pad 311 is in contact with the outer surface of the cleaning rod 304. The annular elastic pad 311 can fill the gap between the cleaning rod 304 and the through groove 312, thereby avoiding back-and-forth collisions between the cleaning rod 304 and the through groove 312 when the cleaning rod 304 is pulled.

[0027] The cleaning assembly 3 also includes an adjustment structure disposed on the baffle plate 1 for adjusting the position of the cleaning rod 304. The adjustment structure includes a set of sliding grooves 305 formed in the inner wall of the through groove 301. Each sliding groove 305 has a sealing plate 306 slidably connected to its inner wall. The ends of the set of sealing plates 306 that are close to each other are respectively connected to the top end and the bottom end of the mounting plate 302. One of the sliding grooves 305 has a threaded hole 307 formed in its inner wall. A retaining bolt is threadedly connected to the inner wall of the threaded hole 307. 308. One end of the retaining bolt 308 contacts the front of one of the sealing plates 306. Tighten the retaining bolt 308 to separate it from the retaining surface of the sealing plate 306. Then pull the mounting plate 302. The ball 303 will drive the cleaning rod 304 to move synchronously until the cleaning rod 304 moves to the appropriate position. Then rotate the retaining bolt 308 to press it back into the sealing plate 306. This can increase the working radius of the cleaning rod 304, adapt to the blockage treatment of slag discharge ports of different sizes, and further ensure the effect of slag cleaning.

[0028] Working principle: When in use, push the baffle 1 to move to a suitable working position, and then extend the cleaning rod 304 through the through slot 312 to the other side of the baffle 1. At this time, the worker holds the end of the cleaning rod 304 to clear the slag blockage in the slag discharge port. When it is necessary to adjust the cleaning angle, the cleaning rod 304 can be deflected directly, and the ball 303 will rotate flexibly on the mounting plate 302, which can treat the slag blockage area without dead angles, saving time and effort and also playing a protective role, further ensuring the effect of slag cleaning.

[0029] If a large area of ​​slag accumulates, first loosen the abutment bolt 308 to separate it from the abutment surface of the sealing plate 306. Then pull the mounting plate 302, and the ball 303 will drive the cleaning rod 304 to move synchronously until the cleaning rod 304 moves to the appropriate position. Then rotate the abutment bolt 308 to press it back into the sealing plate 306. This can increase the working radius of the cleaning rod 304, adapt to the blockage treatment of slag discharge ports of different sizes, and further ensure the effect of slag cleaning.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
