[0002] A boiler is an energy conversion device that converts the chemical energy in fuel into heat energy through combustion. It is commonly used in power generation, industrial production and other technical fields. To ensure the safe operation of a boiler, it is usually necessary to install observation equipment inside the boiler to observe its internal working status.

[0003] However, when the observation equipment is actually working, the ash and slag impurities produced inside the boiler can easily adhere to the lens of the observation equipment, thus affecting the observation field of view of the equipment.

[0004] Therefore, a furnace combustion endoscope device for cleaning impurities at the lens is proposed to solve the above problems. Utility Model Content

[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 a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0030] Please see Figure 1-5 This utility model discloses a furnace combustion endoscope device, including a protective sleeve 1, which is axially inserted into the side wall 01 of the furnace. The sleeve 1 has a first chamber 11 and a second chamber 12 coaxially arranged inside it. The first chamber 11 is located at the end of the protective sleeve 1. The second chamber 12 surrounds the outer periphery of the first chamber 11. The second chamber 12 has an air inlet 121 at the end away from the furnace. The air inlet 121 is connected to an external gas delivery component (not shown in the figure). The gas delivery component is used to deliver airflow into the second chamber 12.

[0031] The observation component 2 includes a lens 21 installed in the first chamber 11 for observing the combustion situation inside the furnace.

[0032] The cleaning component 3 includes a plurality of air nozzles 31 circumferentially distributed at the insertion end of the protective sleeve 1. Each air nozzle 31 is connected to the second chamber 12, and the lens 21 is located at the center of the circumferential distribution of each air nozzle 31, for blowing airflow to the lens 21.

[0033] In practice, when the lens 21 observes the combustion in the furnace, the gas supply component delivers airflow into the second chamber 12 and sprays it out toward the lens 21 through each gas nozzle 31 to form an air curtain, thereby blowing away impurities attached to the lens 21 and cooling the lens 21.

[0034] In this invention, through the operation of the cleaning component 3, when the lens 21 is observing, the air supply component delivers airflow into the second chamber 12 and sprays it towards the lens 21 through each air nozzle 31, thereby blowing out impurities around the lens 21. At the same time, it can form an air curtain on the lens 21 to prevent impurities from blowing towards the lens 21, thus ensuring the field of view of the lens 21.

[0035] It should be noted that the observation component 2 also includes a processing unit 22 disposed in the protective sleeve 1 and a transmission line 23 disposed between the processing unit 22 and the lens 21. The processing unit 22 is connected to an external display terminal (not shown in the figure). The lens 21 is used to send the observed image signal to the processing unit 22 through the transmission line 23 for image processing and then to the display terminal so that the staff can observe. Its structure and function are common knowledge to those skilled in the art, so they will not be described in detail here.

[0036] It should be noted that the insert end of the protective sleeve 1 is equipped with a protective lens cover, which fits against the observation end of the lens 21. While not affecting the operation of the lens 21, it can protect the lens 21 from direct contact with open flames and smoke. The protective lens cover can be made of transparent and high-temperature resistant materials such as high-temperature resistant glass or transparent ceramics.

[0037] In one embodiment, the jet direction of each nozzle 31 is at a preset angle to the surface of the lens 21. When the airflow is blown out from each nozzle 31, its tangential component generates vortices on the surface of the lens 21.

[0038] With this design, when the lens 21 needs to be cleaned, the airflow is ejected through each nozzle 31 to form a counter-current and create a vortex at the lens 21, thereby generating centrifugal force and shear force at the lens 21, which can more effectively blow away the attached impurities.

[0039] In one embodiment, the protective sleeve 1 is further provided with a heat dissipation component 4, including an annular heat exchange chamber 41. The heat exchange chamber 41 is made of a thermally conductive material, is disposed in the first chamber 11 and sleeved on the outer periphery of the lens 21 and is thermally bonded to it.

[0040] Water pipe 42 is axially installed inside protective sleeve 1. Its inlet extends out of protective sleeve 1 and is connected to an external water supply component (not shown in the figure). The water supply component is used to supply cooling medium into water pipe 42. The outlet of water pipe 42 is connected to heat exchange chamber 41 and is used to supply cooling medium into heat exchange chamber 41.

[0041] The reflux chamber 43 is axially arranged inside the protective sleeve 1 and located below the water supply pipe 42. Its inlet is connected to the heat exchange chamber 41, and its outlet extends out of the protective sleeve 1 and is connected to the external recovery pipe (not shown in the figure). The reflux chamber 43 is used to discharge the cooling medium into the recovery pipe.

[0042] With this design, when the lens 21 is working, the water supply component delivers cooling medium to the heat exchange chamber 41 through the water supply pipe 42. At this time, the cooling medium exchanges heat with the lens 21 through the heat exchange chamber 41 to avoid the lens 21 from burning due to excessive temperature and to extend the working time of the lens 21 in the furnace. The cooling medium after heat exchange flows into the return chamber 43 and is discharged to the recovery pipe through its outlet.

[0043] Preferably, the cooling medium can be cooling water.

[0044] In one embodiment, the reflux chamber 43 is made of a thermally conductive material and is thermally bonded to the sidewall of the second chamber 12.

[0045] With this design, when the cooling medium exchanges heat with the lens 21 and flows into the return chamber 43, the cooling medium still has a sufficient cooling temperature. At this time, the cooling mechanism exchanges heat again with the airflow in the second chamber 12 through the return chamber 43, thereby cooling the airflow and enabling the airflow to further cool the lens 21 when cleaning impurities.

[0046] In one embodiment, the second chamber 12 is provided with an adjustment component 5, including an adjustment disk 51 rotatably disposed in the second chamber 12, one end of which is rotatably connected to the lens 21, and the other end is fixedly provided with a first gear 52; the second chamber 12 is also provided with a first power unit 53, the output shaft of which is provided with a second gear 54 meshing with the first gear 52, for driving the lens 21 to rotate axially around the adjustment disk 51; the adjustment disk 51 is rotatably connected to the lens 21;

[0047] The adjustment disk 51 is also provided with a second power unit 55 at the rotational connection between it and the lens 21, which is used to drive the lens 21 to rotate around its rotation axis.

[0048] With this design, when the observation angle of lens 21 needs to be adjusted, the first power unit 53 can drive the second gear 54 to rotate, which in turn drives the adjustment disk 51 to rotate via the first gear 52. At this time, lens 21 rotates together with adjustment disk 51. Then, the second power unit 55 drives lens 21 to rotate around its axis at the point of rotational connection with adjustment disk 51. By cooperating with adjustment disk 51, lens 21 can be rotated in all directions until the observation angle is rotated to the predetermined position.

[0049] In one embodiment, the protective sleeve 1 has a plurality of jet nozzles 13 evenly distributed around its extended end, which communicate with the second chamber 12, and blows air in a directional manner to suppress the adhesion of smoke and dust around the extended end of the protective sleeve 1.

[0050] With this design, when the airflow enters the second chamber 12, part of the airflow is ejected through the corresponding jet nozzle 13 to the extension end of the protective sleeve 1, thereby dispersing the smoke and dust surrounding the protective sleeve 1 and providing a clear observation environment for the lens 21.

[0051] In one embodiment, the protective sleeve 1 is axially slidably inserted into the inner wall of the furnace, and the connection between the protective sleeve 1 and the inner wall of the furnace is a dynamic sealing connection.

[0052] The protective sleeve 1 is provided with a moving part 6 at its extended end, including a moving unit 61 connected to the furnace side wall 01; a connecting frame 62 is also provided between the moving end of the moving unit 61 and the extended end of the protective sleeve 1, and the moving unit 61 drives the protective sleeve 1 to move closer to or further away from the center of the furnace through the connecting frame 62.

[0053] With this design, when the observation position of lens 21 needs to be adjusted, the moving unit 61 drives the protective sleeve 1 to move closer to or further away from the center of the furnace through the connecting frame 62. Lens 21 moves together with the protective sleeve 1 until it is moved to the predetermined position. When it is necessary to remove lens 21, the moving unit 61 drives lens 21 to move away from the center of the furnace until lens 21 is removed from the furnace.

[0054] Preferably, the moving unit 61 may employ a linear module as used in the prior art.

[0055] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0056] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0057] Additionally, "multiple" refers to two or more.
