Description

Technical Field

[0001] The invention belongs to the technical field of boiler equipment, and in particular relates to a temperature measuring device for an outer guard plate of a power station boiler. Background Art

[0002] During power plant boiler operation, the metal outer panels are subject to the effects of high-temperature flue gas and steam. Improper temperature control can lead to increased thermal stress in the metal, causing serious accidents such as deformation, cracking, and even explosion. Installing a temperature measurement device allows for real-time monitoring of the boiler's outer panel temperature, enabling timely detection and resolution of overheating events, effectively preventing safety incidents.

[0003] In the case of a traditional temperature measurement device for the outer guard plate of a power station boiler, when measuring the temperature of the outer guard plate, it is often measured once in a long time, and a temperature measuring instrument such as a temperature gun or a thermocouple is usually used to directly measure the temperature of the outer guard plate of the power station boiler. The temperature measurement personnel need to approach the boiler and aim the temperature measuring instrument at the temperature measuring point on the outer guard plate to obtain the temperature data of the point. However, this method requires the power station boiler to be operated in a high temperature and high pressure environment for measurement. There are certain safety risks in measuring directly close to the boiler, and the measurement operation is time-consuming. Therefore, a temperature measurement device for the outer guard plate of a power station boiler is proposed. Summary of the Invention

[0010] Preferably, a first rain shield is fixedly connected to the upper portion of the power station boiler body, a support column is fixedly connected to the upper portion of the first rain shield, and a second rain shield is fixedly connected to the upper portion of the support column.

[0011] Preferably, a control box is fixedly connected to the upper surface of the fixing plate, and the control box is electrically connected to the first motor, the second motor, and the temperature sensor.

[0012] Preferably, a reinforcement block is fixedly connected to the right portion of the power station boiler body, and the interior of the reinforcement block is fixedly connected to the left end of the fixing plate.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. The present invention controls the start of the first motor through a control box. The rotation of the output shaft of the first motor drives the rotation of the gear. Since the fixed plate is fixedly connected to the right part of the power station boiler body, and the gear and the gear ring are engaged with each other, the rotating ring located inside the I-shaped ring is driven to rotate, thereby enabling the measuring structure at the lower part of the rotating ring to perform circular motion on the outer surface of the outer guard plate. According to the shape of the power station boiler body, this device is mostly a hollow cylinder, thereby meeting the measurement requirements of being fixedly connected to the surface of the power station boiler body, making it more convenient and quick, and enabling the outer guard plates on the surface of the power station boiler body to all be able to perform temperature measurement, thereby reducing measurement risks and improving measurement efficiency.

[0015] 2. The present invention drives the threaded rod located inside the fixed bar to rotate by rotating the second motor output shaft. Then, since the slide groove limits the internal threaded block, and the interior of the internal threaded block is threadedly connected to the surface of the threaded rod, the internal threaded block located inside the slide groove is adjusted up and down, thereby driving the measuring structure connected to the left side of the internal threaded block to measure the temperature of the outer protective plate on the surface of the power station boiler body. This device can change the length of the threaded rod according to the area where the outer protective plate is laid, thereby meeting the temperature measurement of outer protective plates of different heights, reducing the difficulty of measurement.

[0016] 3. The present invention inserts the right part of the T-shaped block into the inner side of the fixed block and then inserts the locking structure into the interior of the fixed block and the T-shaped block, thereby realizing a quick connection between the fixed block and the T-shaped block, and through the operation of the cylinder, drives the connecting plate to move to the side close to the outer guard plate under the limiting action of the guide rod. When the right part of the temperature sensor contacts the outer guard plate, the temperature of the single outer guard plate is measured. When the temperature sensor is separated from the outer guard plate, it enters a state to be measured. The device can quickly realize the disassembly and installation of the measuring structure, thereby facilitating maintenance and protection. Further, the measurement is switched by the operation of the cylinder, thereby avoiding long-term contact between the temperature sensor and the outer guard plate, resulting in a long-term high temperature, thereby causing damage to the temperature sensor.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figures 1 to 7 As shown, an embodiment of the present invention provides a temperature measuring device for the outer guard plate of a power station boiler, comprising a power station boiler body 1, an outer guard plate 2 fixedly connected to the surface of the power station boiler body 1, a fixed plate 3 fixedly connected to the right part of the power station boiler body 1, a support block 4 fixedly connected to the upper part of the fixed plate 3, a first motor 5 fixedly connected to the upper part of the support block 4, a gear 6 fixedly connected to the output shaft of the first motor 5, an I-shaped ring 7 fixedly connected to the upper part of the power station boiler body 1, a rotating ring 8 rotatably connected to the inside of the I-shaped ring 7, a gear ring 9 fixedly connected to the side of the rotating ring 8, the gear ring 9 and the gear 6 are meshed with each other, and a measuring structure is provided at the lower part of the rotating ring 8.

[0027] When the staff needs to measure the temperature of the outer protective plate 2 installed on the outer surface of the power station boiler body 1, the first motor 5 is controlled to start through the control box 29. The rotation of the output shaft of the first motor 5 drives the rotation of the gear 6. Since the support block 4 provides support force for the first motor 5, and the gear 6 and the gear ring 9 are engaged with each other, the gear ring 9 is driven to rotate, and then the rotating ring 8 located inside the I-shaped ring 7 is driven to rotate, and then the measuring structure at the bottom of the rotating ring 8 is driven to make a circular motion along the outer ring of the power station boiler body 1.

[0028] Among them, the lower surface of the rotating ring 8 is fixedly connected to a fixing bar 10, a sliding groove 11 is opened in the middle of the fixing bar 10, the inside of the sliding groove 11 is rotatably connected to a threaded rod 12, the inside of the sliding groove 11 is movably connected to an internal threaded block 13, the inside of the internal threaded block 13 is threadedly connected to the surface of the threaded rod 12, the right part of the fixing bar 10 is fixedly connected to a C-shaped bracket 14, the inner side of the C-shaped bracket 14 is fixedly connected to a second motor 15, and the output shaft of the second motor 15 is fixedly connected to the lower part of the threaded rod 12.

[0029] When the staff needs to measure the temperature of the outer guard plates 2 at different heights, the control box 29 is used to control the start of the second motor 15. However, since the C-shaped bracket 14 provides an installation point and support force for the second motor 15, the rotation of the output shaft of the second motor 15 drives the threaded rod 12 located inside the slide groove 11 to rotate. At the same time, since the internal thread block 13 is limited by the slide groove 11 and can only move up and down, however, since the inside of the internal thread block 13 is threadedly connected to the surface of the threaded rod 12, when the output shaft of the second motor 15 rotates, it drives the internal thread block 13 to rise and fall, and then drives the measuring structure connected to the left side of the internal thread block 13 to measure the temperature of the outer guard plate 2 on the surface of the power station boiler body 1.

[0030] Among them, the measuring structure includes a fixed block 16 fixedly connected to the left part of the internal thread block 13, the internal movably connected to the T-shaped block 17 of the fixed block 16, the internal movably connected to the fixed block 16 is provided with a locking structure, the left part of the T-shaped block 17 is fixedly connected to the cylinder 18, the output shaft of the cylinder 18 is fixedly connected to the connecting plate 19, the rear part of the connecting plate 19 is fixedly connected to the temperature sensor 20, and the left part of the connecting plate 19 is provided with a limiting structure.

[0031] The staff inserts the T-shaped block 17 into the interior of the fixed block 16 so that the hole of the fixed block 16 is aligned with the hole of the T-shaped block 17. Since the interior of the fixed block 16 fits perfectly with the right part of the T-shaped block 17, the locking structure can be easily placed inside the fixed block 16 and the T-shaped block 17. Then, by starting the cylinder 18, the extension and contraction of the output shaft of the cylinder 18 drive the movement of the connecting plate 19. When the temperature sensor 20 contacts the outer guard plate 2, the temperature of the outer guard plate 2 is measured. When the temperature sensor 20 is disengaged from the outer guard plate 2, the temperature of the outer guard plate 2 is not measured. The limiting structure limits the movement of the connecting plate 19 to ensure the stability of the measurement by the temperature sensor 20.

[0032] The locking structure includes a post 21 movably connected to the interior of the fixed block 16 , a connecting strip 22 is fixedly connected to the upper portion of the post 21 , and a limiting strip 23 is fixedly connected to the middle surface of the post 21 .

[0033] The two plugs 21 are connected by a connecting strip 22, and by pulling the connecting strip 22 upwards, the plug 21 can be separated from the inside of the T-shaped block 17 and the fixed block 16. The plug 21 is limited by a limiting strip 23, and the lower surface of the limiting strip 23 is in contact with the upper surface of the fixed block 16.

[0034] The limiting structure includes a guide rod 24 fixedly connected to the left surface of the connecting plate 19 , the left surface of the guide rod 24 is fixedly connected to the limiting circular block 25 , and the surface of the guide rod 24 is movably connected to the inside of the T-shaped block 17 .

[0035] The surface of the guide rod 24 is movably connected to the interior of the T-shaped block 17 to ensure the stability of the connecting plate 19 during movement and guide the movement of the connecting plate 19. The limiting circle 25 prevents the guide rod 24 from escaping from the interior of the T-shaped block 17.

[0036] The upper portion of the power station boiler body 1 is fixedly connected to a first rain shield 26 , the upper portion of the first rain shield 26 is fixedly connected to a support column 27 , and the upper portion of the support column 27 is fixedly connected to a second rain shield 28 .

[0037] The first rain shield 26 is used to shield the rain, preventing the lower components of the first rain shield 26 from excessive contact with rainwater, and the support column 27 provides support for the second rain shield 28, which prevents rainwater from entering the interior of the power station boiler body 1.

[0038] A control box 29 is fixedly connected to the upper surface of the fixing plate 3 , and the control box 29 is electrically connected to the first motor 5 , the second motor 15 , and the temperature sensor 20 .

[0039] The start-up of the first motor 5 and the second motor 15 is controlled by the control box 29, and the temperature value measured by the temperature sensor 20 is collected. The staff can transmit a signal to the control box 29 through ultraviolet rays and output the measured temperature value through an electrical signal.

[0040] The right part of the power station boiler body 1 is fixedly connected with a reinforcement block 30 , and the interior of the reinforcement block 30 is fixedly connected to the left end of the fixing plate 3 .

[0041] By designing the reinforcement block 30 , the connection between the fixing plate 3 and the power station boiler body 1 is reinforced, thereby ensuring stable meshing between the gear 6 and the gear ring 9 .

[0042] Working principle and usage process:

[0043] When the staff needs to measure the temperature of the outer protective plate 2 installed on the outer surface of the power station boiler body 1, the first motor 5 is controlled to start through the control box 29. The rotation of the output shaft of the first motor 5 drives the rotation of the gear 6. Since the support block 4 provides support force for the first motor 5, and the gear 6 and the gear ring 9 are engaged with each other, the gear ring 9 is driven to rotate, and then the rotating ring 8 located inside the I-shaped ring 7 is driven to rotate, and then the measuring structure at the bottom of the rotating ring 8 is driven to make a circular motion along the outer ring of the power station boiler body 1.

[0044] When the staff needs to measure the temperature of the outer guard plates 2 at different heights, the control box 29 is used to control the start of the second motor 15. However, since the C-shaped bracket 14 provides an installation point and support force for the second motor 15, the rotation of the output shaft of the second motor 15 drives the threaded rod 12 located inside the slide groove 11 to rotate. At the same time, since the internal thread block 13 is limited by the slide groove 11 and can only move up and down, however, since the inside of the internal thread block 13 is threadedly connected to the surface of the threaded rod 12, when the output shaft of the second motor 15 rotates, it drives the internal thread block 13 to rise and fall, and then drives the measuring structure connected to the left side of the internal thread block 13 to measure the temperature of the outer guard plate 2 on the surface of the power station boiler body 1.

[0045] The staff inserts the T-shaped block 17 into the interior of the fixed block 16 so that the hole of the fixed block 16 is aligned with the hole of the T-shaped block 17. Since the interior of the fixed block 16 fits perfectly with the right part of the T-shaped block 17, the locking structure can be easily placed inside the fixed block 16 and the T-shaped block 17. Then, by starting the cylinder 18, the extension and contraction of the output shaft of the cylinder 18 drive the movement of the connecting plate 19. When the temperature sensor 20 contacts the outer guard plate 2, the temperature of the outer guard plate 2 is measured. When the temperature sensor 20 is disengaged from the outer guard plate 2, the temperature of the outer guard plate 2 is not measured. The limiting structure limits the movement of the connecting plate 19 to ensure the stability of the measurement by the temperature sensor 20.

[0046] The two plugs 21 are connected by a connecting strip 22, and by pulling the connecting strip 22 upwards, the plug 21 can be separated from the inside of the T-shaped block 17 and the fixed block 16. The plug 21 is limited by a limiting strip 23, and the lower surface of the limiting strip 23 is in contact with the upper surface of the fixed block 16.

[0047] The surface of the guide rod 24 is movably connected to the interior of the T-shaped block 17 to ensure the stability of the connecting plate 19 during movement and guide the movement of the connecting plate 19. The limiting circle 25 prevents the guide rod 24 from escaping from the interior of the T-shaped block 17.

[0048] The first rain shield 26 is used to shield the rain, preventing the lower components of the first rain shield 26 from excessive contact with rainwater, and the support column 27 provides support for the second rain shield 28, which prevents rainwater from entering the interior of the power station boiler body 1.

[0049] The start-up of the first motor 5 and the second motor 15 is controlled by the control box 29, and the temperature value measured by the temperature sensor 20 is collected. The staff can transmit a signal to the control box 29 through ultraviolet rays and output the measured temperature value through an electrical signal.

[0050] By designing the reinforcement block 30 , the connection between the fixing plate 3 and the power station boiler body 1 is reinforced, thereby ensuring stable meshing between the gear 6 and the gear ring 9 .
