Description

Technical Field

[0001] This invention relates to the field of industrial furnace technology, and in particular to a universally adjustable high-temperature lens cooling protection device. Background Technology

[0002] In the field of combustion diagnostics, the flame center is an important reference for studying combustion. It reflects the combustion status of the flame in the furnace space and is closely related to the boiler's safety and economy. The flame center is the highest temperature point in the furnace and also the point with the highest radiation intensity. Changes in the position of the flame center affect both boiler performance and operational safety.

[0003] Combustion involves complex flows and harsh high-temperature environments, posing challenges to contact-based diagnostic methods. Therefore, research on flame structure has primarily focused on non-invasive optical diagnostic methods. In recent years, the rapid development of optical diagnostic technology has led to significant progress in research on complex combustion fields, enabling a more detailed description of flames.

[0004] Unlike other optical diagnostic techniques, chemiluminescence-based combustion diagnostics has two significant advantages. First, its light source, chemiluminescence generated by combustion, eliminates the need for an external laser, resulting in a simple diagnostic system structure, minimal environmental restrictions, and ease of operation. Second, unlike the indirect derivation and verification processes of other diagnostic methods, this chemiluminescence with specific spectral characteristics originates from excited-state free radicals generated by the combustion reaction, directly reflecting combustion characteristics and offering a more intuitive and understandable approach.

[0005] In summary, as precision sensors, cameras and lenses operate in a much warmer environment near the furnace wall than in conventional environments, thus requiring specialized cooling and protection devices.

[0006] Chinese patent CN216668343U discloses a high-temperature lens cooling and protection device for protecting lenses, comprising: a deployment / retraction device; a control module; a circulating cooling pipe; a vortex cooling pipe; a CCD lens; and a temperature sensor. The deployment / retraction device includes a telescopic rod, a drive motor, and a sleeve. The CCD lens is installed inside the sleeve. The telescopic rod is connected to the drive motor. The sleeve is fitted onto the telescopic rod. The circulating cooling pipe is connected to the sleeve and also to the vortex cooling pipe. A temperature sensor is mounted on the sleeve. The protection device has a deployment / retraction device with a temperature sensor and a pressure sensor installed on it. The temperature sensor and pressure sensor are connected to a control unit. The data from the temperature sensor and pressure sensor controls the extension / retraction of the deployment / retraction device to protect the high-temperature lens mounted on the deployment / retraction device.

[0007] However, the above technology has the following problems:

[0008] First, the entire activation and deactivation device of this scheme needs to be pre-installed on the furnace wall. When diagnosing the combustion conditions in the furnace, a lot of human and material resources will be wasted on installing the activation and deactivation device. This will increase the labor force and installation time, increase costs and reduce diagnostic efficiency. Moreover, it cannot meet the diagnostic needs of different combustion conditions in the furnace, thus reducing practicality.

[0009] The cooling control system of this scheme cannot control the intake volume of the vortex cooling gas, which makes it impossible to protect the CMOS lens from overheating based on the different distances between the CMOS lens and the combustion center inside the furnace wall. This results in a shortened lifespan of the CMOS lens and an increase in energy consumption. Summary of the Invention

[0049] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0050] Example 1

[0051] This embodiment provides a universally adjustable high-temperature lens cooling and protection device, such as... Figure 1-4 As shown, it includes a deployment / retraction component, a cooling system, a lens 36, a lens fixing assembly, and an adjustment component;

[0052] The lens fixing assembly includes a fixed sleeve and a movable component. The lens 36 is located inside the fixed sleeve. The movable component is connected to the fixed sleeve and is used to drive the fixed sleeve to move axially. The lens fixing assembly is connected to a deployment and retraction component, which is used to adjust the height and tilt angle of the lens fixing assembly. The cooling system is connected to the fixed sleeve through an adjustment component. The cooling system is used to deliver cooling gas into the fixed sleeve. The adjustment component is used to adjust the rate at which the cooling system delivers cooling gas.

[0053] Working principle: The deployment and retraction component is moved to the vicinity of the furnace wall. The height and tilt angle of the lens fixing assembly are adjusted by the deployment and retraction component, that is, the height and tilt angle of the fixing sleeve are adjusted so that the tilt angle of the fixing sleeve matches the tilt angle of the observation hole on the furnace wall. The fixing sleeve is driven to move axially by the moving component. One end of the fixing sleeve with the lens passes through the observation hole and reaches the inside of the furnace. The combustion characteristics inside the furnace are obtained through the lens. During this process, cooling gas is delivered into the fixing sleeve through the cooling system to cool the lens. The delivery rate of the cooling gas is adjusted by the adjusting component to adjust the cooling rate of the cooling system.

[0054] This solution involves moving the deployment / retraction component near the furnace wall. The height and tilt angle of the lens fixing assembly are adjusted using this component, specifically the height and tilt angle of the fixing sleeve. This ensures the tilt angle of the fixing sleeve aligns with the tilt angle of the observation hole on the furnace wall. A moving component drives the fixing sleeve axially, allowing one end of the fixing sleeve to pass through the observation hole and reach the interior of the furnace. The lens then captures the combustion characteristics within the furnace. During this process, a cooling system supplies cooling gas to the fixing sleeve to cool the lens. The cooling gas delivery rate is adjusted by a regulating component to regulate the cooling rate of the cooling system. This deployment / retraction component allows for rapid adjustment of the device, eliminating the need for installation on the furnace wall, significantly reducing labor costs, improving diagnostic efficiency, and enabling the diagnosis of different combustion conditions within the furnace. This increases practicality while reducing labor costs.

[0055] As a preferred implementation method, such as Figure 4 As shown, the throwing and retraction components include a base 1, a lifting mechanism, a telescopic connector, a base plate 3, a support rod 8, a top plate 9, and an angle adjustment mechanism;

[0056] One end of the telescopic connector is connected to the base 1, and the other end is connected to the base plate 3. The lifting mechanism is fixed above the base 1 and contacts the lower end of the base plate 3. The lifting mechanism is used to raise and lower the height of the base plate 3. The top plate 9 is fixed above the base plate 3 by the support rod 8. The angle adjustment mechanism is fixed below the top plate.

[0057] Specifically, the lifting mechanism includes a first hydraulic cylinder 7, a first hydraulic cylinder push rod 15, a sliding rack 14, and a rotating cam 6;

[0058] The first hydraulic cylinder 7 is fixed on the base 1, and the rotating cam 6 is rotatably fixed on the base 1. The first hydraulic cylinder 7 is driven to connect to the sliding rack 14 through the first hydraulic cylinder push rod 15. The lower end of the rotating cam 6 is geared with the sliding rack 14.

The telescopic rod 5 is located in the second sliding groove 38. The limiting plate 39 is fixed to the lower end of the telescopic rod 5 to ensure that the telescopic rod 5 slides inside the second sliding groove 38.

[0062] The control panel activates the first hydraulic cylinder 7, which moves the first hydraulic cylinder push rod 15 to one end. The first hydraulic cylinder push rod 15 moves to one end, which in turn moves the sliding rack 14 to one end. The sliding rack 14 moves to one end, which in turn rotates the rotating half gear 46. The rotating half gear 46 rotates, which in turn rotates the rotating cam 6. The rotating cam 6 rotates, which in turn moves the rectangular base plate 3 upward. The upward movement of the rectangular base plate 3 in turn moves several evenly distributed circular support rods 8 upward. The upward movement of the several evenly distributed circular support rods 8 in turn moves the rectangular top plate upward, thereby moving the angle adjustment mechanism, the moving mechanism, and the CMOS lens 36 upward, thus realizing the lifting mechanism function.

[0063] Specifically, the angle adjustment mechanism includes a second hydraulic cylinder 10, a rotating plate 11, and a second hydraulic cylinder push rod 18;

[0064] The rotating plate 11 is provided with a first rectangular groove 22 and a rotating component. The first rectangular groove 22 and the rotating component maintain a preset distance.

[0067] The second rectangular groove 26 is arranged parallel to the first rectangular groove 22. The rotary motor 24 is fixed inside one end of the second rectangular groove 26. One end of the rotary screw 25 is connected to the rotary motor 24, and the other end is rotatably fixed to the rotating plate 11. The ball nut block 27 is rotatably connected to the rotary screw 25 and is sleeved on the outside of the rotary screw 25.

The third fixed lifting lug 34 is hinged to the fourth fixed lifting lug 35 through the rotating pin 44. A rectangular column 11 is fixedly connected to the lower end of the third fixed lifting lug 34. The worker can open the second hydraulic cylinder 10 through the control panel to drive the second hydraulic cylinder push rod 18 to move to one end. The movement of the second hydraulic cylinder push rod 18 to one end drives the second fixed lifting lug 20 to move to one end. The movement of the second fixed lifting lug 20 to one end drives the fixed pin 21 to slide in the first slide groove 23. The sliding of the fixed pin 21 in the first slide groove 23 drives the rectangular column 11 to rotate to one end. The rotation of the rectangular column 11 to one end drives the moving mechanism and the CMOS lens 36 to rotate to one end, thus completing the function of the angle adjustment mechanism.

[0069] like Figure 4 , Figure 10 As shown, the lens fixing assembly also includes a third hydraulic cylinder 13, a third hydraulic cylinder push rod 33, and a heat shield 37;

[0070] The third hydraulic cylinder 13 is fixed below the ball nut block 27. The third hydraulic cylinder 13 drives the third hydraulic cylinder push rod 33.

The first hydraulic cylinder push rod 15 moves to one end, which in turn moves the sliding rack 14 to one end. The sliding rack 14 moves to one end, which in turn rotates the rotating half gear 46. The rotating half gear 46 rotates, which in turn rotates the rotating cam 6. The rotating cam 6 rotates, which in turn moves the rectangular base plate 3 upward. The upward movement of the rectangular base plate 3 in turn moves several evenly distributed circular support rods 8 upward. The upward movement of the several evenly distributed circular support rods 8 in turn moves the rectangular top plate upward, thereby moving the angle adjustment mechanism, the moving mechanism, and the CMOS lens 36 upward, thus realizing the lifting mechanism function.

[0079] like Figure 4 , Figure 5 , Figure 7 As shown, the angle adjustment mechanism includes a second hydraulic cylinder 10. The lower end of the second hydraulic cylinder 10 is fixedly connected to a rectangular top plate 9. The lower end of the second hydraulic cylinder 10 is provided with a second hydraulic cylinder push rod 18. The lower end of the second hydraulic cylinder push rod 18 is provided with a first rectangular groove 22. The first rectangular groove 22 is located at the upper end of the rectangular column 11. The inner sides of the first rectangular groove 22 are provided with symmetrically distributed first sliding grooves 23. The second hydraulic cylinder push rod 18 is inserted into the rectangular top plate 9 and fixedly connected to a second lifting lug 20. The interior of the second lifting lug 20 is fixedly connected to a fixing pin 21. The second lifting lug 20 slides in the first rectangular groove 22, and the fixing pin 21 slides in the first sliding groove 23.

[0080] A fourth fixed lifting lug 35 is fixedly connected to the lower end of the side of the rectangular top plate 9 away from the second hydraulic cylinder 10. A third fixed lifting lug 34 is provided between the fourth fixed lifting lugs 35. A rotating pin 44 is inserted between the fourth fixed lifting lugs 35 and the third fixed lifting lug 34. The third fixed lifting lug 34 is hinged to the fourth fixed lifting lug 35 through the rotating pin 44. A rectangular column 11 is fixedly connected to the lower end of the third fixed lifting lug 34. The worker can open the second hydraulic cylinder 10 through the control panel to drive the second hydraulic cylinder push rod 18 to move to one end. The movement of the second hydraulic cylinder push rod 18 to one end drives the second fixed lifting lug 20 to move to one end. The movement of the second fixed lifting lug 20 to one end drives the fixed pin 21 to slide in the first slide groove 23. The sliding of the fixed pin 21 in the first slide groove 23 drives the rectangular column 11 to rotate to one end. The rotation of the rectangular column 11 to one end drives the moving mechanism and the CMOS lens 36 to rotate to one end, thus completing the function of the angle adjustment mechanism.

[0081] like Figure 4 , Figure 6 , Figure 8 As shown, the moving mechanism includes a rotary motor 24, which is fixed inside the lower end of a rectangular column 11. A second rectangular groove 26 is provided on one side of the rotary motor 24. A rotary screw 25 is fixedly connected to one side of the output end of the rotary motor 24, and the other end of the rotary screw 25 is rotatably connected to the rectangular column 11. A rectangular ball screw pair is connected to a rectangular ball nut block 27 on the outer side of the rotary screw 25. The rectangular ball nut block 27 slides in the second rectangular groove 26. A third hydraulic cylinder 13 is fixedly connected to the lower end of the rectangular ball nut block 27. The worker can turn on the rotary motor 24 again through the control panel to drive the rotary motor shaft 25 to rotate. The rotation of the rotary motor shaft 25 drives the rectangular ball nut block 27 to move to one end. The movement of the rectangular ball nut block 27 to one end drives the third hydraulic cylinder 13 and the CMOS lens 36 to move to one end and insert the fixing sleeve 12 into the pre-made hole in the furnace wall 45, thus completing the function of the moving mechanism.

[0082] A pressure sensor is installed inside the fixed sleeve 12 to sense the pressure at the end of the third hydraulic cylinder push rod 33. The width of the rectangular ball nut block 27 is the same as the width of the second rectangular groove 26, which enables the movement mechanism to function. The heat shield 37 is transparent and has high-temperature resistance, which can protect the CMOS lens 36 from damage by high temperature and increase the service life of the CMOS lens 36.

[0083] The cooling control system 43 is equipped with a control panel that can control the start, stop and feedback of the rotary motor 24, guide wheel 2, first hydraulic cylinder 7, second hydraulic cylinder 10, third hydraulic cylinder 13, CMOS lens 36, pressure sensor, temperature sensor and intake volume control valve 42, reducing labor, increasing automation and combustion diagnostic efficiency.

[0084] The universal adjustment function of the device in this scheme is reflected in the multi-degree-of-freedom adjustment of the lens position in space through the telescopic mechanism, as well as the adjustment of the intake volume of cooling gas.

[0085] Based on the above, the working principle of this invention is as follows:

[0086] Workers can control the guide wheels 2 through the control panel in the cooling control system to move the device to the side of the furnace wall 45. Then, they can activate the first hydraulic cylinder 7 through the control panel to move the first hydraulic cylinder push rod 15 to one end. The first hydraulic cylinder push rod 15 moving to one end moves the sliding rack 14 to one end. The sliding rack 14 moving to one end drives the rotating half gear 46 to rotate. The rotating half gear 46 rotating drives the rotating cam 6 to rotate. The rotating cam 6 rotating drives the rectangular base plate 3 to move upward. The rectangular base plate 3 moving upward drives several evenly distributed circular support rods 8 to move upward. The several evenly distributed circular support rods 8 moving upward drives the rectangular top plate to move upward, thereby driving the angle adjustment mechanism, the moving mechanism and the CMOS lens 36 to move upward, realizing the lifting mechanism function.

[0087] Then, the worker can activate the second hydraulic cylinder 10 through the control panel, causing the second hydraulic cylinder push rod 18 to move to one end. The movement of the second hydraulic cylinder push rod 18 to one end causes the second fixed lifting lug 20 to move to one end. The movement of the second fixed lifting lug 20 to one end causes the fixed pin 21 to slide in the first slide groove 23. The sliding of the fixed pin 21 in the first slide groove 23 causes the rectangular column 11 to rotate to one end. The rotation of the rectangular column 11 to one end causes the moving mechanism and the CMOS lens 36 to rotate to one end, thus completing the function of the angle adjustment mechanism.

[0088] Then the worker can turn on the rotary motor 24 again through the control panel to drive the rotary motor shaft 25 to rotate. The rotation of the rotary motor shaft 25 drives the rectangular ball nut block 27 to move to one end. The movement of the rectangular ball nut block 27 to one end drives the third hydraulic cylinder 13 and the CMOS lens 36 to move to one end and insert the fixed sleeve 12 into the pre-made hole in the furnace wall 45, thus completing the function of the moving mechanism.

[0089] The operator can activate the third hydraulic cylinder 13 via the control panel to control the distance between the CMOS lens 36 and the combustion center inside the furnace wall 45. At the same time, the operator can activate the vortex cooling pipe 29 via the control panel to allow vortex cooling air to pass through the first circulating cooling pipe 30, the cooling control system 43, and the second circulating cooling pipe 31 into the fixed sleeve 12 to cool the CMOS lens 36, ensuring the normal operating temperature of the CMOS lens 36. During this process, the operator can also control the intake air volume regulating valve 42 via the control panel to adjust the intake air volume of the vortex cooling air. This allows the operator to protect the CMOS lens 36 from overheating damage based on the different distances between the CMOS lens 36 and the combustion center inside the furnace wall 45, thus completing the function of a universally adjustable high-temperature lens cooling protection device.

It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
