[0007] Preferably, the lifting plate has through holes on both sides along its height direction, and the through holes are respectively fitted onto two sliding rods. The sliding rods extend in a direction parallel to the height direction of the box. Each sliding rod has a fixing plate at both ends.

The fixing plate ensures that there is a preset distance between the sliding rod and the side wall of the box.

[0008] Preferably, the end of the connecting pipe is provided with a splicing ring, and a flange is provided at the mounting hole. The flange and the splicing ring cooperate to connect the connecting pipe to the box body. The side wall of the tray is attached to the outer wall of the connecting pipe. A retaining ring is provided on the connecting pipe. The retaining ring and the splicing ring are coaxially arranged. The distance between the retaining ring and the splicing ring is the same as the thickness of the lifting plate.

Detailed Implementation

[0024] 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.

[0025] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] This utility model provides a waste heat recovery device; please refer to the appendix to the instruction manual. Figure 1 To be continued Figure 3 The waste heat recovery device includes a housing 1 for storing waste heat. The housing 1 has a mounting hole 3 penetrating its side wall, serving as an inlet for storing waste heat. Two sliding rods 5 are symmetrically distributed on the side walls of the housing 1 on either side of the mounting hole 3. The extension direction of the sliding rods 5 is along the height of the housing 1, and the two sliding rods 5 are parallel to each other. A lifting plate 6 passes through the two sliding rods 5, allowing the lifting plate 6 to slide freely along a preset path on the two sliding rods 5. When the lifting plate 6 is positioned below the mounting hole 3, it has a groove 7 with its opening facing the mounting hole 3. The groove 7 is used to support the connecting pipe 12. A rotatable... Linkage mechanism 10, one end of which is connected to housing 1, and the other end is connected to lifting groove. The end of linkage mechanism 10 can also rotate relative to lifting groove. Since the two ends of linkage mechanism 10 are connected to different components and the motion states of each component are different, when linkage mechanism 10 rotates, linkage mechanism 10 bends and the distance between the two connection points decreases. That is to say, when linkage mechanism 10 rotates, it drives lifting groove connected at one end to slide closer to mounting hole 3. The support groove 7 of lifting groove carries connecting pipe 12, so that connecting pipe 12 moves with lifting groove until linkage mechanism 10 aligns the end of connecting pipe 12 with mounting hole 3.

[0027] Please refer to the instruction manual appendix. Figure 2The linkage mechanism 10 includes a first swing rod 101 and a second swing rod 102. One end of the first swing rod 101 is connected to a drive shaft 9, which causes the first swing rod 101 to rotate on the side wall of the housing 1. The axis of the drive shaft 9 is perpendicular to the side wall of the housing 1. A first connecting plate extends from the end of the first swing rod 101 away from the drive shaft 9. The side wall of the first connecting plate is flush with the side wall of the first swing rod 101. The thickness of the first connecting plate is half that of the first swing rod 101, forming a stepped surface at the connection between the first connecting plate and the first swing rod 101. One end of the second swing rod 102 is provided with a rotating shaft 11. The lifting plate 6 has a connecting hole 8 on the side opposite to the support groove 7. The rotating shaft 11 passes through the connecting hole 8 and is mounted on the lifting plate 6. A second connecting plate also extends from the end of the second swing rod 102 opposite to the lifting plate 6. The second connecting plate is flush with the side wall of the second swing rod 102 and its thickness is half the thickness of the second swing rod 102. A stepped surface is formed at the connection between the two. The first swing rod 101 and the second swing rod 102 have the same thickness. The stepped surface on the first swing rod 101 and the step on the second swing rod 102 are connected. The surfaces are fitted together, and a connecting shaft 103 passes through the first and second connecting rods. The axis of the connecting shaft 103 is perpendicular to the first and second connecting plates. Furthermore, the ends of both the first and second connecting plates are arc-shaped. This configuration allows the first and second connecting plates to rotate within a certain angle, enabling the first and second swing rods 101 and 102 to move synchronously. When the drive shaft 9 rotates the first swing rod 101 and pulls the second swing rod 102, the lifting plate 6 connected to the second swing rod 102 is restricted by the sliding rod 5 to only... It can move vertically. The drive shaft 9 of the first swing rod 101 and the rotation shaft 11 of the second swing rod 102 are always on the same vertical line. When the first swing rod 101 rotates, the included angle between the first swing rod 101 and the second swing rod 102 becomes smaller, and the distance between the rotation shaft 11 and the drive shaft 9 decreases. The lifting plate 6 connected to the rotation shaft 11 is lifted and brought closer to the mounting hole 3. The lifting plate 6 is lifted by the rotating linkage mechanism 10 and the connecting pipe 12 is connected to the mounting hole 3, which facilitates the installation by the staff. In addition, a door 2 is provided on the side wall of the box 1 adjacent to the mounting hole 3.

[0028] It should be noted that the lifting plate 6 has through holes on both sides along its height direction. The lifting plate 6 is fitted onto the two sliding rods 5 through the through holes, so that the lifting plate 6 slides only along the extension direction of the sliding rods 5. In addition, each sliding rod 5 is connected to a fixing plate 4 at both ends. The sliding rod 5 is set perpendicular to the fixing plate 4, and the fixing plate 4 is connected to the side wall of the box 1. The fixing plate 4 has a certain length, so that there is a certain distance between the sliding rod 5 and the side wall of the box 1, which prevents the lifting plate 6 from bumping into the box 1 during the sliding process. At the same time, it also provides sufficient docking space for the mounting hole 3 and the connecting pipe 12, which is convenient for the staff to fix and connect.

[0029] Please refer to the instruction manual appendix. Figure 4 The connecting pipe 12 is specifically a cylindrical pipe. The side wall of the connecting pipe 12 can fit against the inner wall of the support groove 7 of the lifting plate 6. A splicing ring 14 is provided on the outer periphery of the end of the connecting pipe 12. Four fixing holes are evenly distributed on the end face of the splicing ring 14. Similarly, the mounting hole 3 extends away from the inner cavity of the box body 1, so that the mounting hole 3 of the box body 1 has a protruding cylinder at one end. A flange 31 is provided on the outer periphery of the cylinder. The end face of the flange 31 is also provided with four fixing holes. Each fixing hole of the flange 31 can correspond one-to-one with each fixing hole of the splicing ring 14. The lifting plate 6 lifts the connecting pipe 12 to the mounting hole 3 and the two ends are matched. Fixing parts are inserted in each fixing hole to fix the connecting pipe 12 to the box body 1, so that the waste heat of the exhaust gas received by the connecting pipe 12 can be transported to the inner cavity of the box body 1.

[0030] Furthermore, a retaining ring 15 is provided on the outer periphery of the connecting pipe 12. The retaining ring 15 is located near the splicing ring 14 and is coaxially arranged with the splicing ring 14. The distance between the retaining ring 15 and the splicing ring 14 is equal to the thickness of the lifting plate 6. That is to say, when the lifting plate 6 carries the connecting pipe 12, the slot 7 is inserted into the part clamped by the retaining ring 15 and the splicing ring 14. Since the distance between the retaining ring 15 and the splicing ring 14 is equal to the thickness of the lifting plate 6, the relative position of the connecting pipe 12 and the lifting plate 6 is locked after the connecting pipe 12 is installed. This prevents the splicing pipe from sliding during the process of lifting the connecting pipe 12, which would affect the subsequent splicing and installation process.

[0031] Please refer to the instruction manual appendix. Figure 4 To be continued Figure 5A conveying pipe assembly 13 is connected to the end of the connecting pipe 12 away from the splicing ring 14. The conveying pipe assembly 13 includes a conveying pipe body 130 and an observation pipe 133. Both the conveying pipe body 130 and the observation pipe 133 are cylindrical pipes, and the diameter of the conveying pipe body 130 is smaller than the diameter of the observation pipe 133. The conveying pipe body 130 is located inside the observation pipe 133, and the observation pipe 133 and the conveying pipe body 130 are coaxially arranged. The inner wall of the conveying pipe body 130 is provided with a heat insulation layer 131, which is used to reduce heat loss during the conveying of exhaust gas. The outer wall of the conveying pipe body 130 is coated with a leak detection agent 132. When the conveying pipe body 130 is damaged and exhaust gas leaks, the high-temperature exhaust gas will cause the leak to leak. The gas detection agent 132 evaporates and is sprayed onto the inner wall of the observation tube 133 by the airflow. Since the observation tube 133 is located on the outside, its sidewall is in contact with the external environment. The temperature of the sidewall of the observation tube 133 is low, and the evaporated gas detection agent 132 re-condenses on the inner wall of the observation tube 133. The observation tube 133 is made of transparent material, and the staff can clearly observe the indication formed by the gas detection agent 132 from the outside. The cavity between the observation tube 133 and the delivery tube body 130 is set to a vacuum state, which further enhances the heat insulation capacity of the delivery tube assembly 13. The observation tube 133 surrounding the delivery tube body 130 also prevents the leaked exhaust gas from escaping into the external environment and avoids environmental pollution.

[0032] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0033] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
