[0002] Combustion monitoring devices are equipment that collects and processes key parameters of the combustion process in real time through sensors, mechanical structures, and data analysis systems. They are used to assess the combustion status, optimize combustion efficiency, and ensure safe and environmentally friendly operation.

[0003] Chinese Patent Publication CN219014282U discloses a boiler combustion monitoring device. The device monitors the temperature of the boiler during combustion using a temperature monitor. When the combustion temperature is too high, the heat generated inside the boiler is transferred to a rubber bladder. The rubber bladder expands due to the heat. When the rubber bladder expands to a certain shape, it presses the alarm button and light button on the inner wall of the boiler protective cover. The alarm button and light button are then turned on, and the audible and visual alarm sounds.

[0004] The aforementioned patented technology can only detect temperature at a single point, and cannot measure different boiler sections, thus leading to measurement errors. Therefore, a real-time monitoring device for the combustion status of power plant boilers is proposed here. Utility Model Content

An emergency cooling component is provided on the top of the base, and a control component is provided on the left side of the base.

[0007] The emergency cooling component includes two water tanks. The upper surface of each water tank is fixedly connected to the bottom surface of two rectangular blocks. A water injection pipe is fixedly connected to the upper surface of each water tank. A threaded cap is threadedly connected to the outer surface of each water injection pipe.

[0008] Each of the water storage tanks has two sets of fixing plates fixedly connected to its bottom surface. Each set of fixing plates consists of two plates, and the inner walls of each pair of fixing plates are rotatably connected to rollers.

[0009] Water pumps are fixedly connected to the two water storage tanks on opposite sides. Each water pump has a fixedly connected pumping pipe at its input end. The end of each pumping pipe near the water storage tank is fixedly connected to the side of the water storage tank away from the base. Each water pump has a fixedly connected output pipe at its output end. The top ends of the two output pipes are fixedly connected to an annular pipe.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0016] Please see Figures 1-4 This utility model provides a real-time monitoring device for the combustion status of a power plant boiler, including a base 1. A detection mechanism 2 is arranged above the base 1. The detection mechanism 2 includes a boiler body 201. The outer surface of the boiler body 201 is fixedly connected to the outer surface of the base 1. Two threaded shafts 204 are rotatably connected to the inner wall of the base 1. Two rectangular blocks 205 are threadedly connected to the outer surface of each threaded shaft 204. Two infrared temperature detectors 206 are fixedly connected to the upper surface of the two rectangular blocks 205. Two support plates 203 are fixedly connected to the left side of the base 1. A stepper motor is fixedly connected to the upper surface of each support plate 203. The stepper motor 202 has its output end fixedly connected to the left end of the threaded shaft 204. An emergency cooling component 3 is set above the base 1. The emergency cooling component 3 includes two water storage tanks 302. The upper surface of each water storage tank 302 is fixedly connected to the bottom surface of two rectangular blocks 205. A water injection pipe 310 is fixedly connected to the upper surface of each water storage tank 302. A threaded cap 309 is threadedly connected to the outer surface of each water injection pipe 310. By setting up the water storage tanks 302, a large amount of cool water can be stored. The presence of the water injection pipes 310 facilitates the delivery of external water sources to the interior of the water storage tanks 302.

[0017] Please see Figures 1-4Each water storage tank 302 has two sets of fixing plates 304 fixedly connected to its bottom surface. Each set of fixing plates 304 consists of two plates. Rollers 307 are rotatably connected to the inner walls of each pair of fixing plates 304. By setting the fixing plates 304, the rollers 307 can be fixed, allowing the rollers 307 to rotate below the water storage tank 302. The presence of the rollers 307 can reduce the resistance encountered when the water storage tank 302 slides.

[0018] Please see Figures 1-3 Two water storage tanks 302 are each fixedly connected to a water pump 305 on their opposite sides. The input end of each water pump 305 is fixedly connected to a water suction pipe 306. The end of each water suction pipe 306 near the water storage tank 302 is fixedly connected to the side of the water storage tank 302 away from the base 1. The output end of each water pump 305 is fixedly connected to an output pipe 303. The top ends of the two output pipes 303 are fixedly connected to an annular pipe 301. A rectangular plate 308 is fixedly connected to the upper surface of each water storage tank 302. The outer surface of the annular pipe 301 is fixedly connected to the inner wall of the two rectangular plates 308. By setting up the water pumps 305, the water pumps 305 and water suction pipes 306 can be used to extract the cool water inside the water storage tank 302. Finally, the water is transported to the inside of the annular pipe 301 through the output pipe 303 and sprayed onto the surface of the boiler body 201 by the annular pipe 301 to achieve the purpose of emergency cooling.

[0019] Please see Figure 1 and Figure 2 A control component 4 is provided on the left side of the base 1. The control component 4 includes a control box 401. The right side of the control box 401 is fixedly connected to the left side of the base 1. A controller 405 is fixedly connected to the inner wall of the control box 401. A movable door 402 is movably hinged to the left side of the control box 401. A pull handle 403 is fixedly connected to the left side of the movable door 402. By providing the controller 405, the various power components in the equipment can be controlled, making the equipment run more smoothly.

[0020] Please see Figure 1 An alarm 404 is fixedly connected to the left side of the base 1. The controller 405 is electrically connected to the alarm 404, the infrared temperature detector 206, the stepper motor 202 and the water pump 305 through wires. With the alarm 404 installed, the alarm 404 can send an alarm signal to the outside world.

[0021] In use, when boiler temperature needs to be detected, the controller 405 controls the stepper motors 202 to operate. The controller 405 transmits electrical signals to the two stepper motors 202 via wires. The power generated by the stepper motors 202 drives the threaded shaft 204 to rotate. When the threaded shaft 204 rotates, it engages with the threaded connection to the rectangular block 205, causing the rectangular block 205 to move laterally. This, in turn, drives the two infrared temperature detectors 206 fixed to the upper surface of the rectangular block 205 to measure the surface of the boiler body 201. The temperature measured by the infrared temperature detectors 206 transmits electrical signals to the controller 405. If the temperature exceeds the standard, the controller 405 transmits information to the alarm 404 via wires, and the alarm 404 sounds an alarm. At the same time, the controller 405 also transmits information to the stepper motors 202 via wires. 02 and water pump 305 control the operation of stepper motor 202 and water pump 305 respectively. When stepper motor 202 is running, it will drive rectangular block 205 and water storage tank 302 fixed on the bottom of rectangular block 205 to move. During the movement of water storage tank 302, the two water pumps 305 can pump water out of the two water storage tanks 302 and deliver it to the inside of the annular pipe 301. Finally, it is sprayed on the surface of boiler body 201 through annular pipe 301 to perform emergency cooling of boiler body 201. When water storage tank 302 moves to the rightmost side of the equipment, stepper motor 202 will run in reverse. After a series of force transmissions, water storage tank 302 will eventually move to the left. This cycle can be repeated to perform emergency cooling of the surface of boiler body 201, thereby effectively avoiding the problem of inaccurate measurement results caused by only being able to measure one part of boiler body 201 during use.
