Description

Technical Field

[0001] This utility model relates to the field of boiler furnace measurement technology, specifically a boiler furnace flame temperature distribution measurement device. Background Technology

[0002] A boiler is a device that uses various fuels, electricity, or other energy sources to heat a contained liquid to certain parameters and provides heat energy through the output of a medium. The boiler furnace is the key area inside the boiler used for fuel combustion and heat transfer. It is the space where fuel mixes with air and burns, and the high-temperature flue gas produced by combustion transfers heat to water or other media inside the boiler, thereby generating steam or hot water. To monitor flame conditions, optimize the combustion process, prevent safety accidents, and extend equipment life, flame temperature distribution measurement equipment needs to be installed inside the boiler furnace.

[0003] Common boiler furnace flame temperature distribution measurement equipment typically consists of a camera, an image acquisition card, and image processing software. The camera is mounted externally to the boiler furnace, capturing images of the furnace interior through an observation hole or a specially designed window. The camera converts the captured flame images into digital signals, which are then transmitted to an image processing unit for further processing. The captured flame images undergo preprocessing to improve image quality and clarity. Temperature-related feature information is extracted from the preprocessed images, and the flame temperature distribution is calculated using a mathematical model to generate a temperature field image or data.

[0004] Traditional boiler furnace flame temperature distribution measurement equipment typically involves attaching a connecting bracket to the outside of the boiler furnace, with the camera bolted to the bracket. The bolting process requires tools, making assembly and disassembly time-consuming. To address this issue, some boiler furnace flame temperature distribution measurement devices add a clamping plate to the connecting bracket. A connector moves the clamping plate along the bracket, clamping and fixing the camera to it, facilitating camera assembly and disassembly. However, this method suffers from inaccurate clamping force control, compromising camera stability and limiting its applicability. Therefore, a new boiler furnace flame temperature distribution measurement device is proposed. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a boiler furnace flame temperature distribution measurement device to solve the aforementioned technical problems that not only cannot guarantee the stability of the camera during use, but also limit its applicability.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a boiler furnace flame temperature distribution measuring device, comprising:

[0009] A support bracket and a connecting seat set on the top of the support bracket, wherein a temperature measuring camera is added to the top of the connecting seat and a hollow connecting tube is connected around the bottom of the connecting seat.

[0010] A connecting cylinder is set around the center of the inner wall of the hollow connecting cylinder, and a triangular block is added to the inner side of the connecting cylinder. A guide rod is installed on the outer side of the triangular block, and a reset spring is sleeved on the surface of the guide rod. The end of the guide rod extends inward through the outer wall of the connecting cylinder and connects to the limit inner plate.

[0011] A connecting column is located directly below the bottom of the connecting cylinder, with a fixed base plate installed at its bottom. A side connecting rod connects the fixed base plate to the support bracket, and a fixed clamping plate is installed on the upper surface of the connecting column, with a movable clamping plate slidably connected to the upper surface of the connecting column. After the support bracket is installed outside the boiler furnace, the connecting seat is placed on top of the support bracket, and the temperature measuring camera is aimed at the observation port of the boiler furnace. After the connecting cylinder descends along the support bracket, when the triangular clamping block descends along the surface of the fixed clamping plate, it drives the guide rod into the connecting cylinder. When the triangular clamping block descends to the center of the guide rod, the triangular clamping block and the guide rod are reset by the action of the return spring. For separation, the movable clamping plate is first raised along the connecting column to fit against the fixed clamping plate, causing the triangular clamping block and the guide rod to move outward, allowing the connecting cylinder to drive the triangular clamping block to rise along the surfaces of the movable and fixed clamping plates, thus separating the connecting seat from the support bracket. On the one hand, this not only ensures the stability of the temperature measuring camera during use but also expands its applicability; on the other hand, it facilitates the assembly and disassembly of the support bracket and the temperature measuring camera. Since temperature measuring cameras are common and mature devices on the market, they will not be described in detail here.

[0012] Preferably, a limiting groove is formed at the top center of the connecting seat, and positioning grooves are formed on both sides of the top of the connecting seat. The connecting seat can be connected to the corresponding structure through the limiting groove and the positioning groove.

[0013] Preferably, a positioning block is slidably connected to the inner cavity of the positioning groove, and a connecting rod is installed on the top of the positioning block. The connecting rod is connected to the temperature measuring camera. When the temperature measuring camera moves horizontally on the top of the connecting seat, the temperature measuring camera moves along the inside of the positioning groove via the connecting rod, preventing the temperature measuring camera from shifting during the horizontal movement.

[0014] Preferably, a rotating handle is mounted at the center of the back side of the connecting seat, and a threaded screw is connected to the center of the inner cavity of the connecting seat. The threaded screw is coaxially connected to the rotating handle. The rotating handle on the connecting seat can drive the threaded screw to rotate and can adjust the direction of rotation of the threaded screw.

[0015] Preferably, a limiting slider is fitted at the center of the surface of the threaded screw, and the bottom of the limiting slider is in contact with the inner wall of the connecting seat. The top of the limiting slider is connected to the temperature measuring camera through a limiting groove. The limiting slider can move along the inner wall of the connecting seat according to the rotation of the threaded screw, and at the same time, the limiting slider can drive the temperature measuring camera to move along the limiting groove, thereby adjusting the usage position of the temperature measuring camera.

[0016] Preferably, the connecting seat has an annular groove at its bottom center, and a rotating plate is added to the top of the hollow connecting cylinder. The hollow connecting cylinder and the rotating plate are slidably connected, and both the hollow connecting cylinder and the rotating plate are T-shaped. The connecting seat can be rotated on the top of the support bracket, and the connecting seat does not need to drive the hollow connecting cylinder and the rotating plate to rotate through the annular groove, thereby adjusting the operating angle and orientation of the temperature measuring camera.

[0017] Preferably, the bottom front and rear ends of the fixed base plate are equipped with fixed seats, and guide posts are inserted into the surface of the fixed seats, with a top block installed at the top of the guide posts. The guide posts can drive the top block to perform lifting and lowering movements on the fixed seats and the fixed base plate.

[0018] Preferably, the top block and the movable plate are opposite each other on the front and back, and both the fixed plate and the movable plate have a tapered design. After the guide column drives the top block to rise and fall, the top block can drive the movable plate to fit tightly against the bottom of the connecting column and the fixed plate.

[0019] Preferably, a compression spring is fitted onto the lower part of the guide post surface, and a limiting base plate is installed at the bottom end of the guide post. A rotating shaft is also added to the front and rear ends of the bottom of the fixed base plate. The guide post can be raised and lowered along the fixed seat and fixed base plate by compressing the spring, and then reset.

[0020] Preferably, a connecting plate is mounted on the surface of the rotating shaft, and an annular pressure plate is added to the end of the connecting plate. The annular pressure plate corresponds to the position of the limiting base plate, and a bearing seat is connected to the end of the rotating shaft. The bearing seat is connected to the fixed base plate, and a drive motor is mounted on the outside of the bearing seat, and the drive motor is coaxially connected to the rotating shaft. The drive motor drives the rotating shaft to rotate on the bearing seat and adjusts the direction of rotation of the rotating shaft. The rotating shaft can drive the annular pressure plate to rotate in the same direction through the connecting plate, so that the annular pressure plate presses upward on the limiting base plate and its connecting structure, thereby facilitating automated operation and making the disassembly and assembly structure more convenient to use.

[0021] (III) Beneficial Effects

[0022] Compared with the prior art, this utility model provides a boiler furnace flame temperature distribution measuring device, which has the following beneficial effects:

[0023] This boiler furnace flame temperature distribution measuring device works by installing a support bracket outside the boiler furnace, placing the connecting seat on top of the support bracket, and aligning the temperature measuring camera with the observation port of the boiler furnace. As the connecting cylinder descends along the support bracket, the triangular locking block descends along the surface of the fixed locking plate, driving the guide rod into the connecting cylinder. When the triangular locking block reaches the center of the guide rod, the triangular locking block and guide rod are reset by the return spring. For separation, the movable locking plate rises along the connecting column and engages with the fixed locking plate, causing the triangular locking block and guide rod to move outwards. This allows the connecting cylinder to drive the triangular locking block to rise along the surfaces of the movable and fixed locking plates, separating the connecting seat from the support bracket. This not only ensures the stability of the temperature measuring camera during use but also expands the applicability of the installation and facilitates the assembly and disassembly of the support bracket and the temperature measuring camera.

Detailed Implementation

[0029] 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.

[0030] This utility model provides a technical solution: a boiler furnace flame temperature distribution measuring device, including: (See details) Figure 1 Support bracket 1, and connecting seat 2 set on the top of support bracket 1, with temperature measuring camera 3 added to the top of connecting seat 2, and hollow connecting tube 12 connected around the bottom of connecting seat 2.

[0031] Please see Figure 3 The connecting cylinder 14 is located around the center of the inner wall of the hollow connecting cylinder 12. A triangular block 15 is added to the inner side of the connecting cylinder 14, and a guide rod 16 is installed on the outer side of the triangular block 15. A reset spring 17 is sleeved on the surface of the guide rod 16. The end of the guide rod 16 extends inward through the outer wall of the connecting cylinder 14 and connects to the limiting inner plate 18.

[0032] Please see Figure 4 The connecting column 19 is located directly below the bottom of the connecting cylinder 14, and a fixed base plate 20 is installed at the bottom of the connecting column 19. A side connecting rod 21 is connected between the fixed base plate 20 and the support bracket 1. A fixed clamping plate 22 is installed on the upper surface of the connecting column 19, and a movable clamping plate 23 is slidably connected to the upper surface of the connecting column 19. After the support bracket 1 is installed outside the boiler furnace, and the connecting seat 2 is placed on top of the support bracket 1, and the temperature measuring camera 3 is aligned with the observation port of the boiler furnace, the connecting cylinder 14 descends along the support bracket 1. When the triangular locking block 15 descends along the surface of the fixed locking plate 22, it drives the guide rod 16 into the connecting cylinder 14. When the triangular locking block 15 descends to the center of the guide rod 16, the triangular locking block 15 and the guide rod 16 are reset under the action of the return spring 17. When separating, the movable locking plate 23 is first raised along the connecting column 19 to fit against the fixed locking plate 22, so that the triangular locking block 15 and the guide rod 16 move outward, so that the connecting cylinder 14 can drive the triangular locking block 15 to rise along the surface of the movable locking plate 23 and the fixed locking plate 22, separating the connecting seat 2 from the support bracket 1. On the one hand, this not only ensures the stability of the temperature measuring camera 3 during use, but also improves the applicability of the installation; on the other hand, it facilitates the disassembly and assembly of the support bracket 1 and the temperature measuring camera 3. Meanwhile, the temperature measurement camera 3 is a common and mature device on the market, so it will not be described in detail here.

[0033] Please see Figure 2A limiting groove 4 is provided at the center of the top of the connecting seat 2, and positioning grooves 5 are provided on both sides of the top of the connecting seat 2. The connecting seat 2 can be connected to the corresponding structure through the limiting groove 4 and the positioning grooves 5. A positioning block 6 is slidably connected to the inner cavity of the positioning groove 5, and a connecting rod 7 is installed on the top of the positioning block 6. The connecting rod 7 is connected to the temperature measuring camera 3. When the temperature measuring camera 3 moves horizontally on the top of the connecting seat 2, the temperature measuring camera 3 drives the positioning block 6 to move along the inside of the positioning groove 5 through the connecting rod 7, so as to prevent the temperature measuring camera 3 from deviating during the horizontal movement. A rotating handle 8 is installed at the center of the back of the connecting seat 2, and a threaded screw 9 is connected to the center of the inner cavity of the connecting seat 2. The threaded screw 9 is coaxially connected to the rotating handle 8. The rotating handle 8 can drive the threaded screw 9 to rotate on the connecting seat 2, and the direction of rotation of the threaded screw 9 can be adjusted. A limiting slider 10 is fitted at the center of the surface of the threaded screw 9, with its bottom fitting against the inner wall of the connecting seat 2. The top of the limiting slider 10 is connected to the temperature measuring camera 3 via a limiting groove 4. The limiting slider 10 can move along the inner wall of the connecting seat 2 according to the rotation of the threaded screw 9, and simultaneously, the limiting slider 10 can drive the temperature measuring camera 3 to move along the limiting groove 4, thereby adjusting the position of the temperature measuring camera 3. An annular groove 11 is provided at the center of the bottom of the connecting seat 2, and a rotating plate 13 is added to the top of the hollow connecting cylinder 12. The hollow connecting cylinder 12 and the rotating plate 13 are slidably connected, and both the hollow connecting cylinder 12 and the rotating plate 13 are T-shaped. The connecting seat 2 can be rotated on the top of the support bracket 1, and the connecting seat 2 does not need to drive the hollow connecting cylinder 12 and the rotating plate 13 to rotate via the annular groove 11, thereby adjusting the operating angle and orientation of the temperature measuring camera 3.

[0034] Please see Figure 4A fixed base plate 20 has a fixed seat 24 installed at its bottom front and rear ends. A guide post 25 is inserted into the surface of the fixed seat 24, and a top block 26 is installed at the top of the guide post 25. The guide post 25 can drive the top block 26 on the fixed seat 24 and the fixed base plate 20 to perform lifting and lowering movements. The top block 26 corresponds to the front and back of the movable clamping plate 23, and both the fixed clamping plate 22 and the movable clamping plate 23 have a tapered design. After the guide post 25 drives the top block 26 to rise and fall, the top block 26 can drive the movable clamping plate 23 to fit tightly between the bottom of the connecting post 19 and the fixed clamping plate 22. A compression spring 27 is sleeved on the lower part of the surface of the guide post 25, and a limit plate 28 is installed at the bottom end of the guide post 25. A rotating shaft 29 is also added at the bottom front and rear ends of the fixed base plate 20. The guide post 25 can be reset after rising and falling along the fixed seat 24 and the fixed base plate 20 by compressing the spring 27. A connecting plate 30 is mounted on the surface of the rotating shaft 29, and an annular pressure plate 31 is added to the end of the connecting plate 30. The annular pressure plate 31 is positioned corresponding to the limiting base plate 28, and a bearing seat 32 is connected to the end of the rotating shaft 29. The bearing seat 32 is connected to the fixed base plate 20, and a drive motor 33 is mounted on the outside of the bearing seat 32. The drive motor 33 is coaxially connected to the rotating shaft 29. The drive motor 33 drives the rotating shaft 29 to rotate on the bearing seat 32 and adjusts the direction of rotation of the rotating shaft 29. The rotating shaft 29 can drive the annular pressure plate 31 to rotate in the same direction through the connecting plate 30, so that the annular pressure plate 31 presses the limiting base plate 28 and its connecting structure upward, thereby facilitating automated operation and making the disassembly and assembly structure more convenient to use.

[0035] This solution involves installing the support bracket 1 outside the boiler furnace, placing the connecting seat 2 on top of the support bracket 1, and aiming the temperature measuring camera 3 at the observation port of the boiler furnace. After the connecting cylinder 14 descends along the support bracket 1, when the triangular locking block 15 descends along the surface of the fixed locking plate 22, it drives the guide rod 16 into the connecting cylinder 14. When the triangular locking block 15 descends to the center of the guide rod 16, the triangular locking block 15 and the guide rod 16 are reset under the action of the return spring 17. When separating, the movable locking plate 23 is first raised along the connecting column 19 and attached to the fixed locking plate 22, so that the triangular locking block 15 and the guide rod 16 move outward, allowing the connecting cylinder 14 to drive the triangular locking block 15 to rise along the surface of the movable locking plate 23 and the fixed locking plate 22, thus separating the connecting seat 2 from the support bracket 1. When the temperature measuring camera 3 moves horizontally on top of the connecting seat 2, it causes the positioning block 6 to move along the inside of the positioning groove 5 via the connecting rod 7. The rotating handle 8 on the connecting seat 2 can drive the threaded screw 9 to rotate and adjust the direction of the threaded screw 9. The limiting slider 10 can move along the inner wall of the connecting seat 2 according to the direction of the threaded screw 9. At the same time, the limiting slider 10 can drive the temperature measuring camera 3 to move along the limiting groove 4. The connecting seat 2 can rotate on top of the support bracket 1, and the connecting seat 2 does not need to drive the hollow connecting cylinder 12 and the rotating plate 13 to rotate via the annular groove 11. The drive motor 33 drives the rotating shaft 29 to rotate on the bearing seat 32 and adjusts the direction of the rotating shaft 29. The rotating shaft 29 can drive the annular pressure plate 31 to rotate in the same direction via the connecting plate 30, so that the annular pressure plate 31 presses the limiting base plate 28 and its connecting structure upward. The guide column 25 can drive the top block 26 on the fixed seat 24 and the fixed base plate 20. When the guide column 25 moves up and down, the top block 26 moves up and down. The top block 26 can then move the movable plate 23 to fit tightly between the bottom of the connecting column 19 and the fixed plate 22. The guide column 25 can be moved up and down along the fixed seat 24 and the fixed base plate 20 by squeezing the spring 27, and then reset.
