Description

Technical Field

[0001] The utility model relates to the technical field of incinerators, in particular to a fire observation hole structure of a main engine for garbage power generation. Background Art

[0002] As a widely adopted method for treating municipal domestic waste in developed countries, garbage incineration power generation conforms to the three principles of "reduction, harmlessness, and resource utilization". The main equipment for garbage incineration is the incinerator. The incinerator is large in scale, usually several stories high, and obtains energy conversion through the input of garbage and high-temperature incineration. Based on the need to monitor and manage the incineration process, multiple observation ports are provided on the incinerator. According to the observation positions in cooperation with the stairs beside, multiple observation ports can be set in the height direction, which is an important means to understand the internal incineration situation.

[0003] The existing observation ports usually adopt visual transparent materials and are observed through external monitoring equipment or manually. Only the combustion situation at the height corresponding to the observation hole can be seen. Due to the large space inside the furnace and the three-dimensional combustion space, the observation effect is not good, and the comprehensive observation of the incineration situation cannot be carried out. Content of the Utility Model

[0004] The purpose of the utility model is to provide a fire observation hole structure of a main engine for garbage power generation, which can realize a three-dimensional view of the combustion situation inside the incinerator and improve the comprehensive observation ability.

[0005] In order to achieve the above purpose, the utility model is realized through the following technical solutions:

[0006] A fire observation hole structure of a main engine for garbage power generation includes a transparent spherical cover. The edge of the spherical cover is provided with an annular plate extending radially outward. An arc-shaped slide bar is rotatably installed on the annular plate relative to its circumferential direction. The arc-shaped slide bar is a semi-circular shape coaxial with the annular plate. Both ends of the arc-shaped slide bar are respectively provided with relatively fixed shaft sleeves. A semi-circular curved frame adapted to the inner circumferential surface of the spherical cover is arranged inside the spherical cover. Both ends of the curved frame are respectively fixed with swing shafts coaxial with it. The swing shafts are respectively rotatably connected with the two shaft sleeves. An observation module is arranged on the curved frame.

[0007] The observation module is a mirror panel, and the mirror panel has a reflective surface on the inner side.

[0008] The observation module is a camera, and the camera is fixed on the side surface adjacent to the curved panel and the spherical cover.

[0009] A large gear ring coaxial with the circular chute is arranged outside the circular chute. The large gear ring is fixed on the annular plate. One or both outer ends of the shaft sleeves are rotatably installed with rotating gears coaxial with them. The rotating gears are meshed with the large gear ring, and the rotating gears are driven by a motor.

[0010] One or two swing gears driven by a motor are rotatably mounted on the shaft sleeves. A driven gear coaxial with the swing shaft is fixed on the swing shaft, and the swing gear meshes with the driven gear.

[0011] A circular chute coaxial with the annular plate is fixed on the annular plate. The width of the notch of the circular chute is smaller than the width of the bottom of the chute. The cross section of the arc-shaped slide bar is an inverted T shape adapted to the cross section of the circular chute. The arc-shaped slide bar is located in the circular chute and is slidably matched along the circumferential direction of the circular chute. Two ends of the arc-shaped slide bar are respectively fixedly provided with bumps penetrating through the notch of the circular chute, and the bottom of the shaft sleeve is fixed on the bumps.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] With this observation hole structure, the entire curved frame can be rotated circumferentially around the annular plate through the arc-shaped slide bar, and the spherical swing of the curved frame relative to the spherical cover can be realized through the shaft sleeve and the swing shaft, which is convenient for obtaining a more three-dimensional visual field and comprehensively observing the combustion situation in the incinerator more comprehensively.

[0021] The present utility model will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by this application.

[0022] Embodiment 1:

[0023] The fire viewing hole structure in this example adopts a manual operation and manual observation mode.

[0024] The main structure includes a spherical cover 1. The edge of the spherical cover 1 is provided with an annular plate 2 extending radially outward. The annular plate 2 is used to be fixed on the incinerator. The spherical cover 1 is used to be installed on the hole position of the incinerator and is recessed into a spherical shape towards the furnace interior. The transparent structure of the sphere can obtain a more complete observation effect and has a coherent and wider field of view.

[0025] A circular chute 3 coaxial with it is fixed on the annular plate 2. The width of the notch of the circular chute 3 is smaller than the width of the bottom of the chute, so that the cross-section of the chute is an inverted T shape. An arc-shaped slide bar 4 slidably connected with it is arranged in the circular chute 3. The arc-shaped slide bar 4 is semi-circular. The cross-section of the arc-shaped slide bar 4 is an inverted T shape adapted to the cross-section of the circular chute 3. The arc-shaped slide bar 4 is located in the circular chute 3 and is in circumferential sliding fit along the circular chute 3. Convex blocks penetrating through the notch of the circular chute 3 are respectively fixed at both ends of the arc-shaped slide bar 4.

[0026] A semi-circular curved frame 6 coaxial with it is arranged in the spherical cover 1. The curved frame 6 is semi-circular and coaxial, concentric and adapted to the spherical cover 1. Swing shafts 7 coaxial with it are respectively fixed at both ends of the curved frame 6. Sleeve 8 is sleeved on the swing shaft 7. The swing shaft 7 is rotatably connected with the sleeve 8. The two sleeves 8 are respectively fixed on the two convex blocks, so that based on the sliding of the arc-shaped slide bar 4, the curved frame 6 can rotate circumferentially relative to the annular plate 2.

[0027] Based on the above structure, both ends of the curved frame 6 realize circumferential rotation relative to the spherical cover 1 through the sleeve 8 and the arc-shaped slide bar 4. At the same time, both ends of the curved frame 6 realize rotation relative to the sleeve 8 through the swing shaft 7, so that the curved frame 6 can swing towards the interior of the spherical cover 1. Based on the combination of the two rotation structures, the curved frame 6 realizes rotation in two dimensions, so that the matching relationship at various angles in the spherical cover 1 can be obtained.

[0028] A mirror panel 9 is provided at the center of the curved frame 6. The mirror panel 9 has a reflecting surface on the inner side. By adjusting the rotation angle and swing angle of the curved frame 6, the reflecting surface reflects the combustion conditions at various angles near the spherical cover 1 in the furnace. People can obtain a 360-degree continuous and in-depth observation effect of the area near the spherical cover 1 in the furnace at a certain distance, achieving a comprehensive grasp of the combustion conditions within the three-dimensional space.

[0029] At the same time, when the device is not in use, the arc-shaped slide 4 can be located in the lower semi-circle of the circular chute 3, and the curved frame 6 can droop in the lower part without blocking most of the area of the spherical cover 1. When simply observing, it is possible to directly observe through the spherical cover 1, and the curved frame 6 gives way without blocking the line of sight, making it flexible and convenient to use.

[0030] Embodiment 2:

[0031] The fire observation hole structure in this example adopts a remote mode.

[0032] This example also uses a spherical cover 1 with a transparent structure, and an annular plate 2 is provided on the periphery of the spherical cover 1.

[0033] The circular chute 3, arc-shaped slide 4, semi-circular curved frame 6, swing shaft 7, and bushing 8 with the same structure are adopted;

[0034] On this basis, a camera for collecting visual images is fixedly installed on the curved frame 6 in this example, thereby realizing the display of the internal combustion conditions on a remote computer.

[0035] In terms of remote control, the swing and rotation of the curved frame 6 are controlled by electricity. An external large gear ring 10 coaxial with it is provided outside the circular chute 3, and the large gear ring 10 is fixed on the annular plate 2. One or two outer ends of the bushing 8 are rotatably installed with a rotating gear 11 coaxial with it, and the rotating gear 11 meshes with the large gear ring 10, and the rotating gear 11 is driven by a motor.

[0036] A swing gear 12 driven by a motor is also rotatably installed on one of the bushings 8. A driven gear 13 coaxial with it is fixed on the swing shaft 7, and the swing gear 12 meshes with the driven gear 13 to realize the drive control of the swing of the curved frame 6.

[0037] Based on the above structure, the motor can be used to drive and control the circumferential rotation of the curved frame 6 relative to the annular plate 2 and the inner and outer swing of the curved frame 6 relative to the spherical cover 1 respectively, facilitating people to remotely control the observation angle of the curved frame 6, and comprehensively adjusting the observation angle up, down, left, and right, realizing the comprehensive video monitoring and image acquisition of the combustion conditions in the furnace near the spherical cover 1.
