Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0027] Second, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present invention. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments.

[0028] Embodiment 1

[0029] Referring to Figures 1 to 5 , which is the first embodiment of the present invention. This embodiment provides a flame detection device that can cool down and remove dust from the overall device through water cooling and air cooling, maintain a suitable working temperature and environment, and quickly cool down after work for easy disassembly and replacement.

[0030] Specifically, the device main body 100 includes an outer sleeve water cooling component 101, an inner sleeve air cooling component 102 penetrating through an eccentric position of the outer sleeve water cooling component 101, an arc-shaped protective sleeve 103 arranged at an eccentric position at one end of the outer sleeve water cooling component 101, a double adjustment component 104 connected to the arc-shaped protective sleeve 103, and a double locking component 105 arranged on the arc-shaped protective sleeve 103 and on one side of the double adjustment component 104.

[0031] Furthermore, the outer sleeve water cooling component 101 includes a front cover 101a and a rear cover 101b respectively arranged at its two ends, an access port 101c arranged at the top of the outer sleeve water cooling component 101, a water inlet pipe 101d connected to the rear cover 101b, a cooling port 101e penetrating through the top of the front cover 101a, a release groove 101f arranged on the cooling port 101e, and an installation port 101g penetrating through its eccentric position and adapted to the inner sleeve air cooling component 102.

[0032] Furthermore, the inner sleeve air cooling component 102 includes an air inlet nozzle 102a communicated with its top, an optical fiber 102b arranged inside it, a signal processor 102c and a flame detection lens 102d respectively arranged at both ends of the optical fiber 102b, a fixing ring 102e connected to the flame detection lens 102d, and a plurality of groups of air outlet openings 102f arranged in an array on the fixing ring 102e;

[0033] Both ends of the inner sleeve air cooling component 102 extend out of the installation port 101g, and one end extends into the arc-shaped protective sleeve 103, and the flame detection lens 102d is arranged inside the arc-shaped protective sleeve 103;

[0034] The air inlet nozzle 102a is adapted to the access port 101c and extends out of the access port 101c.

[0035] Further, the dual adjustment assembly 104 includes an adjustment column 104a, a connection plate 104b disposed on one side of the adjustment column 104a, a sealing plate 104c connected to the connection plate 104b and disposed in the unsealing groove 101f, a pressing plate 104d disposed at the bottom of the adjustment column 104a, a hinge block 104e connected to the pressing plate 104d, an arc-shaped hollow diversion disc 104f connected to the bottom of the hinge block 104e, a hinge column 104g hinged to the hinge block 104e and having both ends connected to the inner wall of the arc-shaped protective sleeve 103, and a torsion spring 104h disposed on the hinge column 104g and connected to the hinge block 104e and the inner wall of the arc-shaped protective sleeve 103.

[0036] It should be noted that the optical fiber 102b, the signal processor 102c, and the flame detection lens 102d can all adopt existing technologies, and the installation method of the torsion spring 104h can adopt existing technologies. Only for illustration in the figure, so it will not be elaborated. The connection plate 104b is set horizontally. By setting the torsion spring 104h, the connection plate 104b has a tendency to maintain its original state. When the connection plate 104b deflects, in the absence of resistance, it will finally return to the horizontal under the action of the torsion spring 104h.

[0037] Further, the adjustment column 104a includes a locking port 104a-1 disposed on one side thereof, and an arc-shaped extrusion block 104a-2 disposed on the top of the locking port 104a-1.

[0038] Further, the dual locking assembly 105 includes a support frame 105a connected to the top of the arc-shaped protective sleeve 103, a sleeve 105b connected to the top of the support frame 105a, an adjustment rod 105c disposed in the middle of the sleeve 105b and extending towards both ends thereof, a locking block 105d connected to one end of the adjustment rod 105c, and a spring 105e disposed outside the adjustment rod 105c and connected to the locking block 105d and the sleeve 105b at both ends. The spring 105e is a high-temperature resistant spring and is in a compressed state.

[0039] Further, the locking block 105d includes an arc-shaped contact head 105d-1 disposed on the top thereof, and a card slot 105d-2 disposed on the bottom thereof. The arc-shaped end of the arc-shaped contact head 105d-1 is disposed on the top, and the arc-shaped end of the arc-shaped extrusion block 104a-2 inside the locking port 104a-1 is disposed on the bottom. The two cooperate with each other. When the arc-shaped extrusion block 104a-2 presses the arc-shaped contact head 105d-1, the arc-shaped contact head 105d-1 will press the spring 105e and retract.

[0040] Preferably, the outer diameter of the inner sleeve air-cooling component 102 is the same as that of the arc-shaped hollow diversion disc 104f. The arc-shaped hollow diversion disc 104f is arranged at one end of the air outlet 102f, and its inner diameter is the same as the diameter of the flame detector lens 102d, with a gap left between the two. The arc-shaped protective sleeve 103 includes a viewing port 103a arranged at its end and an adjustment port arranged at its top and adapted to the adjustment column 104a; the flame detector lens 102d is horizontally arranged in the middle of the viewing port 103a.

[0041] It should be noted that the air inlet nozzle 102a is connected to the cooling fan, and the water inlet pipe 101d is communicated with the cooling water, so that a water-cooling cavity C and an air-cooling cavity D are respectively formed inside the outer sleeve water-cooling component 101 and the inner sleeve air-cooling component 102, and the water-cooling cavity C and the air-cooling cavity D are sealed from each other. During detection, the outer sleeve and the inner sleeve are simultaneously cooled and dissipated heat by the cooling water in the water-cooling cavity C, and the inner sleeve and the arc-shaped protective sleeve 103 are cooled and dissipated heat by the air-cooling cavity D.

[0042] The arc-shaped protective sleeve 103 is arranged in an arc-shaped inclined shape to protect the interior during detection, preventing most of the dust from directly falling into the cylinder and accumulating dust, which affects the work. The arc-shaped hollow diversion disc 104f is arranged at one end of the air outlet 102f as a secondary protection to prevent dust from entering the inner sleeve air-cooling component 102 through the air outlet 102f, and when the cold air is discharged through the air outlet 102f, it can hit the arc-shaped hollow diversion disc 104f. The cold air speed at the top is reduced and fills the top cavity of the arc-shaped protective sleeve 103 for full contact and cooling. The cold air speed at the bottom is reduced and a small part of the dust is discharged in real time through the air duct A formed between the arc-shaped hollow diversion disc 104f and the arc-shaped protective sleeve 103 to prevent dust accumulation, so as to realize real-time cooling and dust removal during the detection process, and avoid the cold air having a certain impact on the boiler combustion by changing the wind direction and reducing the wind speed, improving the accuracy of detection.

[0043] Refer to Figure 1 and Figure 2 Through the eccentrically arranged inner sleeve air-cooling component 102, the flame detector lens 102d can be visually observed in the horizontal direction through the hollow opening of the arc-shaped hollow diversion disc 104f and the viewing port 103a. Similarly, the non-contact part between the eccentrically arranged arc-shaped protective sleeve 103 and the front cover 101a of the outer sleeve water-cooling component 101 forms a spraying area E.

[0044] During use, the staff only needs to connect the device main body 100 with a cold air blower and cooling water, fill the water-cooling cavity C and the air-cooling cavity D, then push the detection device into the boiler along a straight line to detect the combustion effect. The outer sleeve protects the inner sleeve. The water-cooling cavity C conducts water-cooling heat dissipation on the relatively high-temperature outer sleeve and serves as the second layer of protection for the inner sleeve, increasing the service life of the optical fiber. The air-cooling cavity D conducts cooling heat dissipation on the inner sleeve and the optical fiber in the inner sleeve. The cooling air finally enters the arc-shaped protective sleeve 103 through the air outlet 102f, conducts heat dissipation and cooling on the inner cavity of the arc-shaped protective sleeve 103, and adjusts the wind speed and direction under its action to perform real-time dust cleaning inside the cylinder, avoiding affecting the combustion effect.

[0045] When the detection device needs to be disassembled, the staff only needs to press the adjustment column 104a with an external object, so that the entire adjustment column 104a moves downward until the locking block 105d pops into the locking port 104a-1 under the action of the spring 105e. The adjustment column 104a has a tendency to move upward under the action of the torsion spring 104h. Since the plane at the bottom of the locking port 104a-1 is engaged with the card slot 105d-2 at the bottom of the locking block 105d, the two are more tightly engaged, and the adjustment column 104a is maintained at a certain height.

[0046] During this process, it will prompt the pressing plate 104d to drive the hinge block 104e and the arc-shaped hollow diversion disc 104f to rotate around the hinge column 104g, so that the surface of the arc-shaped hollow diversion disc 104f tends to fit the arc-shaped top of the arc-shaped protective sleeve 103, gradually releasing the closure of the air outlet 102f, increasing the air outlet speed of the cooling air, and facilitating the increase of the cooling speed; while the pressing plate 104d descends, it will make the sealing plate 104c move in the unsealing groove 101f through the connecting plate 104b, gradually exposing the cooling port 101e. The cooling water in the water-cooling cavity C is sprayed onto the arc-shaped protective sleeve 103 through the cooling port 101e provided in the spraying area E, performing dust flushing on it while performing external water-cooling and internal cavity air-cooling. The height of the hinge block 104e can be adjusted adaptively to facilitate a larger angle deflection.

[0047] When the cooling efficiency needs to be improved, continue to press the adjustment column 104a with an external object, so that the arc-shaped extrusion block 104a-2 at the top of the locking port 104a-1 extrudes the locking block 105d outward and can continue to move downward. Finally, the card slot 105d-2 at the bottom of the locking block 105d is engaged with the fixed surface B at the top of the adjustment column 104a, realizing the complete exposure of the cooling port 101e and the unsealing of the air outlet 102f, thereby improving the cooling efficiency. When disassembling, only need to pull one end of the adjustment rod 105c to release the lock, and the adjustment column 104a pops out under the action of the torsion spring.

[0048] In summary, when in use, the present invention cools the outer sleeve and the inner sleeve through water cooling, and cools and removes dust inside the inner sleeve through air cooling, ensuring a suitable working temperature and working environment, improving the detection accuracy, and adjusting the cooling efficiency through a dual adjustment component after the detection is completed, so that the device can be quickly cooled, facilitating subsequent disassembly and assembly.
