Description

Technical Field

[0001] This invention relates to the field of boiler testing technology, and in particular to a real-time online detection instrument for boiler expansion. Background Technology

[0002] The development of new energy power generation and the overcapacity of coal-fired power generation are gradually driving the transformation of coal-fired power plants towards greater flexibility. Continuous low-load operation or deep peak shaving of thermal power units, especially coal-fired power units, has become the norm. Peak shaving involves changes in the internal thermophysical properties and thermal stress distribution of the boiler. When boiler deformation exceeds the capacity of its components, it can cause damage, cracking, or even unplanned shutdowns, seriously threatening the safe operation of the power plant. Therefore, real-time continuous monitoring of boiler expansion is of great significance for the safe operation of boilers.

[0003] Currently, mechanical pressure testing equipment is generally used to test the expansion pressure inside a boiler. However, this equipment can easily be damaged when subjected to strong pressure shocks. Therefore, we propose a real-time online detection instrument for boiler expansion to solve the aforementioned problems. Summary of the Invention

[0004] In view of the technical problem that the detection equipment is easily damaged when subjected to strong pressure impact, the present invention proposes a real-time online detection instrument for boiler expansion.

[0005] This invention proposes a real-time online monitoring instrument for boiler expansion, comprising a mounting cover, a detection component connected inside the mounting cover, the left side of the detection component extending to the outside of the mounting cover, a gas supply pipe connected to the detection component, a detection box fixedly mounted on the top of the mounting cover, the top end of the gas supply pipe extending into the detection box and fixedly connected to the right inner wall of the detection box, a pressure measuring component mounted on the top end of the gas supply pipe, the pressure measuring component being connected to the left inner wall of the detection box, and a display fixedly mounted on the front of the detection box, the display being connected to the pressure measuring component.

[0006] With the above structure, after the detection component receives the gas pressure inside the boiler, it can transport the propelled gas through the gas supply pipe to the pressure measuring component, thereby enabling real-time monitoring of the gas pressure inside the boiler and transmitting the monitored data to the display for display, thus facilitating real-time observation by the staff.

[0007] Preferably, the detection assembly includes a support plate, a pushing member, and a support cover. The support plate is fixedly installed on the inner wall of the mounting cover. The pushing member passes through the support plate and is connected to it. The support cover is fixedly installed on the inner wall of the mounting cover. The left side of the pushing member extends into the support cover and is connected to the inner wall of the support cover. The bottom end of the gas delivery pipe extends into the support cover and is fixedly connected to the right inner wall of the support cover. The left side of the pushing member extends to the outer side of the mounting cover.

[0008] Furthermore, after the pushing component is subjected to air pressure, it can move. At this time, the gas in the support cover can be transported to the pressure measuring component through the air supply pipe, so that the pressure measuring component can operate and perform pressure detection.

[0009] Preferably, the pushing component includes a force-bearing plate, a moving rod, and a push plate. The moving rod passes through the support plate and is slidably connected to the support plate. The right end of the moving rod extends into the support cover and is fixedly connected to the push plate. The push plate is slidably and sealingly connected to the inner wall of the support cover. The left end of the moving rod extends to the outside of the mounting cover and is fixedly connected to the force-bearing plate.

[0010] Furthermore, the pressure plate can be used to sense the gas pressure inside the boiler and can push the moving rod to move. At this time, under the push of the push plate, the gas in the support cover can be transported to the pressure measuring component.

[0011] Preferably, a return spring is sleeved on the moving rod located on the right side of the support plate, and the left and right ends of the return spring are fixedly connected to the right side of the support plate and the left side of the push plate, respectively.

[0012] Furthermore, when the gas pressure inside the boiler decreases, it can drive the push plate to reset to the left.

[0013] Preferably, the pressure measuring assembly includes a mounting bracket, a pressure rod, a pressure plate, a pressure sensor, a connecting cover, a sealing box, a sealing gasket, and an elastic member. The mounting bracket is fixedly installed on the left inner wall of the testing box, the pressure sensor is fixedly installed on the left inner wall of the testing box and located inside the mounting bracket, the left end of the pressure rod extends into the mounting bracket and is fixedly connected to the pressure plate, the pressure rod is slidably connected to the mounting bracket, the sealing box is slidably connected to the covering, the connecting cover is fixedly installed on the right inner wall of the testing box, the sealing gasket is fixedly installed on the right side of the sealing box, the sealing gasket is slidably connected to the inner wall of the connecting cover, the gas supply pipe is connected to the connecting cover, the elastic member is installed inside the sealing box, and the right end of the pressure rod extends into the sealing box and is connected to the elastic member.

[0014] Furthermore, after the gas enters the connecting cover, it can push the sealing box to move, which in turn can drive the pressure rod to move through the elastic component, and then apply pressure to the pressure sensor through the pressure plate, so that the pressure sensor can start to work.

[0015] Preferably, the elastic component includes a movable ring, two rotating rods, two connecting plates, two support shafts, and two torsion springs. The movable ring is slidably connected inside the sealed box. The right end of the pressure rod is fixedly connected to the left side of the movable ring. The two rotating rods are symmetrically rotatably connected to the left inner wall of the sealed box, and both connecting plates are slidably connected inside the movable ring. The support shaft passes through the corresponding connecting plate and is rotatably connected to the connecting plate. The rear end of the support shaft is fixedly connected to one end of the rotating rod. The torsion spring is sleeved on the corresponding support shaft and is located on the front side of the connecting plate. The front end and rear end of the torsion spring are fixedly connected to the front end of the support shaft and the front side of the connecting plate, respectively.

[0016] Furthermore, when the sealed box moves, a pulling force can be applied to the two rotating rods, which will cause the support shaft and the connecting plate to rotate, so that the torsion spring is under stress. Therefore, the torsion spring under stress can provide elastic support to the pressure rod, which can effectively prevent the pressure sensor from being subjected to excessive force.

[0017] Preferably, multiple fixing plates are fixedly installed at equal intervals on the front and rear sides of the mounting cover, and fixing holes are provided on the fixing plates.

[0018] Furthermore, this device can be easily installed on a boiler.

[0019] Preferably, a rubber ring is fixedly installed on the front side of the mounting cover.

[0020] Furthermore, by utilizing rubber rings, this device can achieve good anti-slip capability when installed on a boiler.

[0021] The beneficial effects of this invention are:

[0022] 1. In this invention, after the device is installed on the boiler, the force plate is placed inside the boiler. When the force plate is subjected to the gas pressure inside the boiler, it can push the moving rod to the right, thereby pushing the push plate to move. When the push plate moves, the gas in the support cover can be transported to the connecting cover through the gas supply pipe. When the gas pressure in the connecting cover increases, it can provide a thrust to the sealing box, causing the sealing box to move to the left. At this time, under the push of the elastic member, the pressure rod can move to the left, and the pressure plate can be used to apply pressure to the pressure sensor. After being pressed, the pressure sensor can convert the pressure value into a digital signal and transmit it to the display, thereby realizing the real-time display of the gas pressure inside the boiler.

[0023] 2. In this invention, when the sealing box is moved, the two connecting plates can be moved by the two rotating rods. At this time, the two connecting plates will move away from each other, and the support shaft can be rotated by the rotating rods. At this time, the torsion spring can be applied to the torsion spring, so that the torsion spring is in a stressed state. The torsion spring in the stressed state can provide elastic support to the pressure rod through the moving ring. Therefore, it can avoid the pressure plate applying too much pressure to the pressure sensor, which would damage the pressure sensor.

[0024] The present invention has a reasonable structure. After the force plate is subjected to the gas pressure inside the boiler, the generated pressure can be transmitted to the pressure sensor. The pressure sensor can then be used to detect the gas pressure inside the boiler in real time. Furthermore, with the buffer support of the elastic component, the pressure sensor is protected from excessive hard pressure, thus preventing damage to the pressure sensor.

[0031] The present invention will be further explained below with reference to specific embodiments.

[0032] refer to Figure 1-5This embodiment proposes a real-time online detection instrument for boiler expansion, including a mounting cover 1. A detection component is connected inside the mounting cover 1. The left side of the detection component extends to the outside of the mounting cover 1. A gas supply pipe 10 is connected to the detection component. A detection box 11 is fixedly installed on the top of the mounting cover 1. The top end of the gas supply pipe 10 extends into the detection box 11 and is fixedly connected to the right inner wall of the detection box 11. A pressure measuring component is installed on the top end of the gas supply pipe 10 and is connected to the left inner wall of the detection box 11. A display 12 is fixedly installed on the front side of the detection box 11 and is connected to the pressure measuring component.

[0033] With the above structure, after the detection component receives the gas pressure inside the boiler, it can push the gas through the gas supply pipe 10 to the pressure measuring component, thereby enabling real-time monitoring of the gas pressure inside the boiler and transmitting the monitored data to the display 12 for display, thus facilitating real-time observation by the staff.

[0034] In this embodiment, the detection component includes a support plate 4, a pushing member, and a support cover 7. The support plate 4 is fixedly installed on the inner wall of the mounting cover 1. The pushing member passes through the support plate 4 and is connected to the support plate 4. The support cover 7 is fixedly installed on the inner wall of the mounting cover 1. The left side of the pushing member extends into the support cover 7 and is connected to the inner wall of the support cover 7. The bottom end of the gas supply pipe 10 extends into the support cover 7 and is fixedly connected to the right inner wall of the support cover 7. The left side of the pushing member extends to the outside of the mounting cover 1.

[0035] After the pushing component is subjected to air pressure, it can move. At this time, the gas in the support cover 7 can be transported to the pressure measuring component through the air supply pipe 10, so that the pressure measuring component can operate and perform pressure detection.

[0036] In this embodiment, the pushing component includes a force-bearing plate 6, a moving rod 5, and a push plate 8. The moving rod 5 passes through the support plate 4 and is slidably connected to the support plate 4. The right end of the moving rod 5 extends into the support cover 7 and is fixedly connected to the push plate 8. The push plate 8 is slidably connected to the inner wall of the support cover 7. The left end of the moving rod 5 extends to the outside of the mounting cover 1 and is fixedly connected to the force-bearing plate 6.

[0037] The pressure plate 6 can be used to sense the gas pressure inside the boiler and can push the moving rod 5 to move. At this time, under the push of the push plate 8, the gas in the support cover 7 can be transported to the pressure measuring component.

[0038] In this embodiment, a return spring 9 is sleeved on the moving rod 5 and located on the right side of the support plate 4. The left and right ends of the return spring 9 are fixedly connected to the right side of the support plate 4 and the left side of the push plate 8, respectively.

[0039] When the gas pressure inside the boiler decreases, it can drive the push plate 8 to reset to the left.

[0040] In this embodiment, the pressure measuring assembly includes a mounting frame 13, a pressure rod 15, a pressure plate 16, a pressure sensor 14, a connecting cover 18, a sealing box 19, a sealing gasket 20, and an elastic member. The mounting frame 13 is fixedly installed on the left inner wall of the detection box 11. The pressure sensor 14 is fixedly installed on the left inner wall of the detection box 11 and is located inside the mounting frame 13. The left end of the pressure rod 15 extends into the mounting frame 13 and is fixedly connected to the pressure plate 16. The pressure rod 15 is slidably connected to the mounting frame 13. The sealing box 19 is slidably connected to the cover 18. The connecting cover 18 is fixedly installed on the right inner wall of the detection box 11. The sealing gasket 20 is fixedly installed on the right side of the sealing box 19 and is slidably connected to the inner wall of the connecting cover 18. The gas supply pipe 10 is connected to the connecting cover 18. The elastic member is installed inside the sealing box 19. The right end of the pressure rod 15 extends into the sealing box 19 and is connected to the elastic member.

[0041] After the gas enters the connecting cover 18, it can push the sealing box 19 to move, thereby driving the pressure rod 15 to move through the elastic member, and then the pressure plate 16 can apply pressure to the pressure sensor 14, so that the pressure sensor 14 can start working.

[0042] In this embodiment, the elastic component includes a movable ring 21, two rotating rods 23, two connecting plates 22, two support shafts 24, and two torsion springs 17. The movable ring 21 is slidably connected inside the sealed box 19. The right end of the pressure rod 15 is fixedly connected to the left side of the movable ring 21. The two rotating rods 23 are symmetrically rotatably connected to the left inner wall of the sealed box 19, and the two connecting plates 22 are slidably connected inside the movable ring 21. The support shafts 24 pass through the corresponding connecting plates 22 and are rotatably connected to the connecting plates 22. The rear end of the support shafts 24 is fixedly connected to one end of the rotating rods 23. The torsion springs 17 are sleeved on the corresponding support shafts 24, and the torsion springs 17 are located on the front side of the connecting plates 22. The front end and rear end of the torsion springs 17 are fixedly connected to the front end of the support shafts 24 and the front side of the connecting plates 22, respectively.

[0043] When the sealed box 19 moves, it can provide tension to the two rotating rods 23, which can cause the support shaft 24 and the connecting plate 22 to rotate, so that the torsion spring 17 is under stress. Therefore, the torsion spring 17 under stress can provide elastic support to the pressure rod 15, which can effectively prevent the pressure sensor 14 from being subjected to excessive force.

[0044] In this embodiment, multiple fixing plates 2 are fixedly installed at equal intervals on the front and rear sides of the mounting cover 1, and fixing holes are provided on the fixing plates 2.

[0045] This device can be easily installed on a boiler.

[0046] In this embodiment, a rubber ring 3 is fixedly installed on the front side of the mounting cover 1.

[0047] By using rubber ring 3, this device can achieve good anti-slip capability when installed on a boiler.

[0048] In this embodiment, after the device is installed on the boiler, the force plate 6 is placed inside the boiler. When the force plate 6 is subjected to the internal gas pressure of the boiler, it can push the moving rod 5 to the right, thereby pushing the push plate 8 to move. When the push plate 8 moves, the gas in the support cover 7 can be transported to the connecting cover 18 through the gas supply pipe 10. After the gas pressure inside the connecting cover 18 increases, it can provide a thrust to the sealing box 19, causing the sealing box 19 to move to the left. At this time, under the push of the elastic member, the pressure rod 15 can move to the left, and the pressure plate 16 can apply pressure to the pressure sensor 14. After being pressed, the pressure sensor 14 can detect the pressure... The value is converted into a digital signal and transmitted to the display 12, which enables real-time display of the gas pressure inside the boiler. When the sealing box 19 moves, the two connecting plates 22 can be moved by the two rotating rods 23. At this time, the two connecting plates 22 will move away from each other, and the support shaft 24 can be rotated by the rotating rods 23. At this time, the torque can be applied to the torsion spring 17, so that the torsion spring 17 is in a stressed state. The torsion spring 17 in a stressed state can provide elastic support to the pressure rod 15 through the moving ring 21, so as to avoid the pressure plate 16 applying too much pressure to the pressure sensor 14, which would damage the pressure sensor 14.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
