Description

Technical Field

[0001] This utility model relates to the technical field of the power industry, and in particular to a device for sealing leaks in flues. Background Technology

[0002] Power plant flue gas ducts are key systems in energy conversion facilities such as thermal power plants and waste incineration power plants, used to transport flue gas generated during combustion, which contains waste gas and dust. They serve as a "bridge" connecting boilers, incinerators, and subsequent environmental protection equipment, such as desulfurization, denitrification, dust removal devices, and chimneys. They are a critical component of the power plant's "flue gas treatment system," and their performance is related to the safe operation of the unit, environmental compliance, and economic efficiency. The design of flue gas ducts places great emphasis on corrosion resistance, low resistance, and ease of maintenance.

[0003] The process involves manually covering the leak with a sealing plate, pressing the plate against the outer wall of the flue using a bracket, and then manually tightening it with a screw or applying pressure with a hydraulic rod to ensure a tight fit between the sealing plate and the flue wall. Using the plate's own elasticity or a sealing gasket, an uninflated sealing bag is inserted into the flue through the leak or a nearby inspection door. Compressed air is then pumped into the bag using an external air pump, causing it to expand and adhere tightly to the inner wall of the flue. The friction between the bag and the wall, along with the expansion pressure, seals the leak. While this method offers some improvement in the power industry's technical capabilities, it lacks the ability to be quickly disassembled and the sealing method itself has shortcomings.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 3 and Figure 4 An embodiment of this utility model is provided: a flue leak sealing device, including a semi-circular pipe clamp 1, a quick-release mechanism 2 fixedly connected to the top outer side of the semi-circular pipe clamp 1, the quick-release mechanism 2 is used for quick disassembly of the device, a sealing mechanism 3 is installed at the right outer side of the semi-circular pipe clamp 1, the sealing mechanism 3 is used for sealing the flue leak, and a hinge 18 is fixedly connected to the lower outer side of the semi-circular pipe clamp 1.

[0034] The quick-release mechanism 2 includes a base block 201, which is located on the top outer side of the semi-circular pipe clamp 1. A main block 202 is fixedly connected to the upper end of the base block 201. A rod hole 203 is opened at the left outer side of the main block 202. A secondary block 204 is fixedly connected to the upper end of the base block 201. A guide groove 205 is opened in the middle of the upper end of the secondary block 204. A guide block 206 is slidably connected to the middle of the guide groove 205. A sliding groove 207 is opened at the lower end of the guide groove 205. Multiple stop blocks 208 are fixedly connected to the left and right ends of the sliding groove 207. A stop block 209 is fixedly connected to the middle of the lower end of the guide block 206. A stop block 209 is fixedly connected to the middle of the right end of the guide block 206. A stop bar 210 is fixedly connected. A grooved round rod 211 is fixedly connected to the middle of the left end of the guide block 206. A rotating hole 212 is opened at the lower left end of the main block 202. A long rotating rod 213 is slidably connected to the middle of the rotating hole 212. A short rotating rod 214 is connected to the right end of the long rotating rod 213. A gear 215 is fixedly connected to the middle of the long rotating rod 213. A locking block 216 is fixedly connected to the upper end of the gear 215. A transverse hole 4 is opened on the front and rear sides of the outer wall of the main block 202. A locking rod 5 is slidably connected to the middle of the transverse hole 4. A knob 6 is fixedly connected to the front end of the locking rod 5. A stop round rod 7 is fixedly connected to the middle of the locking rod 5.

[0035] Specifically, the main block 202 and the secondary block 204 are fixed on the base block 201 to form a basic frame. First, rotate the knob 6, which is fixedly connected to the locking rod 5. Rotating the knob will cause the locking rod 5 to move synchronously. The stop rod 7 on the locking rod 5 is pulled outward through the transverse hole 4, releasing the restriction on the locking block 216. The grooved rod 211 is fixed on the guide block 206, pushing the guide block 206 to slide along the guide groove 205 on the secondary block 204, causing the grooved rod 211 to slide into the rod hole 203. The guide block 206 is fixed with a second stop 209 and a stop rod 210. The slide groove 207 is fixed with a first stop 208. When the guide block 206 slides in the guide groove 205, the first stop 208 will interact with the stop rod 209. Block 209 and stop bar 210 restrict the sliding position of guide block 206 and prevent guide block 206 from sliding out of guide groove 205. A rotating hole 212 is provided on main block 202. Long rotating rod 213 is slidably connected to rotating hole 212. By rotating long rotating rod 213, the gear 215 connected to it is driven to rotate. Since the gears 215 mesh with each other, when one gear 215 rotates, it will drive the other gear 215 fixed to the short rotating rod 214 meshing with it to rotate synchronously, realizing the opening and closing action of the locking block 216 on gear 215. After the grooved round rod 211 is completely slid into rod hole 203, the operator resets the previously operated parts.

[0036] Reference Figure 2 and Figure 5The sealing mechanism 3 includes a circular hole 301, which is located on the outer right end of the semi-circular pipe clamp 1. A sealing gasket 302 is slidably connected to the middle of the circular hole 301. A threaded push rod 303 is fixedly connected to the right end of the sealing gasket 302. An outer cylinder 304 is fixedly connected to the outer right end of the semi-circular pipe clamp 1. Multiple slots 305 are equidistantly opened around the outer right end of the outer cylinder 304. An internal threaded rotating sleeve 306 is rotatably connected to the outer right end of the outer cylinder 304. Multiple fixing plates 307 are equidistantly fixedly connected to the upper and lower ends of the outer side of the internal threaded rotating sleeve 306. A rotating shaft 308 is rotatably connected to the middle of the fixing plate 307. A small rod 309 is fixedly connected to the middle of the rotating shaft 308. A sealing groove 8 is opened on the outer left end of the threaded push rod 303. A rubber ring 9 is fixedly connected to the middle of the sealing groove 8. Multiple fixing rods 14 are fixedly connected to the upper middle end of the outer side of the semi-circular pipe clamp 1. A handle rod 15 is fixedly connected to the upper end of the fixing rod 14.

[0037] Specifically, the outer cylinder 304 is fixed around the circular hole 301 on the semi-circular pipe clamp 1. An internally threaded rotating sleeve 306 is rotatably connected inside the outer cylinder 304. When the position of the threaded push rod 303 needs to be adjusted, simply rotate the internally threaded rotating sleeve 306. Because the internally threaded rotating sleeve 306 is threadedly connected to the threaded push rod 303, the threaded push rod 303 can move inwards and outwards, thereby controlling its extension and retraction length. A sealing gasket 302 is fixedly installed at the front end of the threaded push rod 303. When the threaded push rod 303 moves inwards to the appropriate position, the sealing gasket 302 will tightly fit against the leakage point, effectively sealing it. To address the leak, after adjusting the threaded push rod 303 to the optimal sealing position, it needs to be fixed. The operator will push the small rod 309, which is installed through the fixing plate 307 and the rotating shaft 308, downwards so that the small rod 309 is precisely inserted into the slot 305, thereby locking the position of the threaded push rod 303. To further enhance the airtightness of the device, a sealing groove 8 is provided on the threaded push rod 303, and a rubber ring 9 is installed in the sealing groove 8. The rubber ring 9 has good elasticity and sealing performance, which can enhance the airtightness. The handle rod 15 is installed in the upper middle part of the semi-circular pipe clamp 1 through the fixing rod 14 to realize the transportation of the device.

[0038] Reference Figure 1 , Figure 2 and Figure 6 A bolt 10 is threaded to the left side of the outer side of the semicircular pipe clamp 1. A warning plate 11 is slidably connected to the middle of the bolt 10. A detection hole 12 is opened in the upper middle part of the right side of the semicircular pipe clamp 1. A threaded air pressure detector 13 is threaded to the right end of the detection hole 12. Bolt 2 16 is threaded to the lower front and rear ends of the semicircular pipe clamp 1. A high temperature color-changing sheet 17 is slidably connected to the middle of the bolt 2 16.

[0039] Specifically, the indicator plate 11 is installed on the right side of the semi-circular pipe clamp 1 by bolt 10, which facilitates subsequent replacement and maintenance. The indicator plate 11 can clearly mark the usage precautions of the device, which can effectively warn and guide. On the right side of the semi-circular pipe clamp 1, a detection hole 12 is opened, which is suitable for the installation of the threaded air pressure detector 13. The threaded air pressure detector 13 is model Y40ZT. The threaded air pressure detector 13 is installed on the detection hole 12 by threaded connection. It detects the air pressure change inside the device and judges the airtightness of the device. The high-temperature color-changing sheet 17 is installed at the lower end of the semi-circular pipe clamp 1 by bolt 2 16. When the temperature of the pipe rises to a certain level, it will have a clear color change. The staff can judge the temperature of the pipe by observing the color.

[0040] Working principle: The main block 202 and the secondary block 204 are fixed on the bottom block 201 respectively. First, rotate the knob 6 so that the stop rod 7 of the clamping rod 5 fixed to it can be pulled outward through the transverse hole 4 to release the restriction on the clamping block 216. Fix the grooved rod 211 on the guide block 206. As the guide groove 205 opened on the secondary block 204 slides into the rod hole 203, the second stop block 209 and the stop rod 210 are fixed on the guide block 206. The first stop block 208 is fixed in the sliding groove 207 to limit the sliding position of the guide block 206 and prevent it from sliding out. By rotating the long rotating rod 213 that is slidably connected to the rotating hole 212 opened on the main block 202, the gear 215 is rotated. When one gear 215 rotates, the gear 215 that meshes with it and is fixedly connected to the short rotating rod 214 rotates, realizing the opening and closing of the clamping block 216 on the gear 215. After the grooved rod 211 slides in, all of them are reset.

[0041] The outer cylinder 304 is fixed around the circular hole 301 on the semi-circular pipe clamp 1. By rotating the internal threaded sleeve 306 that is rotatably connected to the outer cylinder 304, the threaded push rod 303 that is threadedly connected to the internal threaded sleeve 306 moves inward and outward. A sealing gasket 302 is also fixed in front of the threaded push rod 303 for sealing the leakage point. After rotating, the small rod 309 installed through the fixing plate 307 and the rotating shaft 308 is pushed downward to lock the small rod 309 into the slot 305.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
