Description

Technical Field

[0001] This utility model belongs to the technical field of heat energy recovery and utilization boxes, specifically a heat energy recovery and utilization box with a pipe auxiliary connection structure. Background Technology

[0002] The heat recovery and utilization box utilizes the heat contained in the flue gas and transfers the heat to the water source that needs to be heated through the internal heat exchange water pipes, thereby realizing the recovery and utilization of heat. It is of great significance in energy conservation, emission reduction and improving energy utilization efficiency.

[0003] Traditional heat recovery boxes have a relatively simple overall structure. When heated flue gas enters the box through the vent, the heat is transferred to the heat exchange water pipes, heating the water and achieving heat exchange for heat recovery. Before use, two sets of ventilation ducts need to be connected to the vents at both ends of the box. Due to the large diameter of the ventilation ducts, manual support is required during installation to prevent them from falling off, increasing labor intensity and posing certain safety hazards. Summary of the Invention

[0004] The purpose of this invention is to provide a heat energy recovery and utilization box with a pipeline auxiliary docking structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat energy recovery and utilization box with a pipe auxiliary docking structure, comprising a box body, a vent, a support column, and a heat exchange water pipe. Vents are provided at both ends of the box body. The support column is connected to the bottom of the box body. The heat exchange water pipe is installed inside the box body. A support frame is welded to the outside of the support column. A fixing block is installed on the surface of the support frame. A connecting rod is connected to the inside of the fixing block through a bearing. A large gear and a small gear are welded to the outside of the connecting rod. An electric push rod is installed near the bottom of the support frame close to the fixing block. A first rack is connected to the output end of the electric push rod. A second rack is meshed with the back of the small gear. The tops of the two second racks are connected to an arc-shaped support seat.

[0006] Preferably, the second rack and the fixed block form a sliding structure.

[0007] Preferably, the large gear and the first rack form a meshing structure.

[0008] Preferably, a connecting block is installed on the top of the housing, and a connecting shaft is connected to the inner side of the connecting block.

[0009] Preferably, a threaded post is rotatably connected to the outer side of the connecting shaft, and a threaded sleeve is threadedly connected to the outer side of the threaded post.

[0010] Preferably, a baffle is provided on the top of the box, and a plug rod is connected to the bottom of the baffle.

[0011] Preferably, a connecting plate is welded to the outer side of the plug rod.

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

[0013] 1. When the electric push rod of this utility model is running, its end drives the first rack to move away from the support frame. When the first rack moves, it drives the large gear to move through meshing. When the large gear moves, it rotates through the connecting rod. At the same time, the connecting rod rotates and drives the two sets of small gears to rotate through meshing. When the end of the electric push rod extends to the maximum distance, the arc-shaped support can rise to the designated position. At this time, one end of the ventilation duct can be placed inside the arc-shaped support, and the end of the ventilation duct is at the same height as the end of the box, so that the duct and the box can be fixed. The arc-shaped support can provide auxiliary support for the duct and facilitate the connection between the two ends of the duct and the box without the need for manual support by the staff. This allows for quick connection and fixation of the duct, thereby improving the safety of duct connection and reducing labor intensity.

[0014] 2. When using this utility model, the baffle can be moved to the top of the box, and the two sets of plug rods at the bottom of the baffle can be inserted into the corresponding connecting blocks. When the threaded column moves, it rotates through the connecting shaft. When the threaded column rotates to the inside of the connecting plate and can no longer rotate, the threaded sleeve can be tightened, so that the threaded sleeve slides through the threaded column and squeezes and fixes the connecting plate, thereby installing and fixing the plug rods and the baffle. The baffle can cover the top of the box to prevent rainwater and snow from accumulating on the top of the box, thereby avoiding heat loss inside the box and ensuring the heat exchange efficiency of this utility model.

[0021] 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.

[0022] Please see Figures 1-4 It is understood that this utility model provides a technical solution: a heat energy recovery and utilization box with a pipe auxiliary docking structure, including a box body 1, a vent 2, a support column 3 and a heat exchange water pipe 4. Vents 2 are provided at both ends of the box body 1. The support column 3 is connected to the bottom of the box body 1. The heat exchange water pipe 4 is installed inside the box body 1. A support frame 5 is welded to the outside of the support column 3. A fixing block 6 is installed on the surface of the support frame 5. A connecting rod 7 is connected to the inside of the fixing block 6 through a bearing. A large gear 8 and a small gear 9 are welded to the outside of the connecting rod 7 respectively. An electric push rod 10 is installed near the bottom of the support frame 5 near the fixing block 6. A first rack 11 is connected to the output end of the electric push rod 10. A second rack 12 is meshed with the back of the small gear 9. An arc-shaped support seat 13 is connected to the top of the two second racks 12. A sliding structure is formed between the second rack 12 and the fixing block 6. A meshing structure is formed between the large gear 8 and the first rack 11.

[0023] In practice, before using the heat energy recovery and utilization box, the ventilation duct needs to be installed and connected to both ends of the box 1. The ventilation duct is not shown in the diagram. Start the electric push rod 10. When the electric push rod 10 is running, its end drives the first rack 11 to move away from the support frame 5. When the first rack 11 moves, it drives the large gear 8 to move through meshing. When the large gear 8 moves, it rotates through the connecting rod 7. At the same time, the connecting rod 7 rotates and drives the two sets of small gears 9 to rotate through meshing. When the small gears 9 rotate, they drive the second rack 12 to move away from the support frame 5 through meshing. When the second rack 12 moves, it drives the arc-shaped support seat 13 to move. When the end of the electric push rod 10 extends to the maximum distance, the arc-shaped support seat 13 can rise to the designated position. At this time, one end of the ventilation duct can be placed inside the arc-shaped support seat 13, and the end of the ventilation duct is at the same height as the end of the box 1, so that the duct and the box 1 can be fixed.

[0024] See Figures 1-4 As can be seen, the arc-shaped support seat 13 can provide auxiliary support for the pipe and facilitate the connection between the pipe and both ends of the box 1 without the need for manual support by the staff. This allows for quick connection and fixation of the pipe, thereby improving the safety of pipe connection and reducing labor intensity.

[0025] See Figure 1 , Figure 2 and Figure 5 It can be seen that a connecting block 14 is installed on the top of the box 1, a connecting shaft 15 is connected to the inner side of the connecting block 14, a threaded post 16 is rotatably connected to the outer side of the connecting shaft 15, a threaded sleeve 17 is threadedly connected to the outer side of the threaded post 16, a baffle 18 is provided above the box 1, a plug rod 19 is connected to the bottom of the baffle 18, a connecting plate 20 is welded to the outer side of the plug rod 19, and a through hole matching the size of the threaded post 16 is opened inside the connecting plate 20.

[0026] In practical implementation, when using this utility model, the baffle 18 is moved to the top of the housing 1, and the two sets of plug rods 19 at the bottom of the baffle 18 are respectively inserted into the corresponding connecting blocks 14, so that the connecting plate 20 on the plug rod 19 is located at the top of the connecting block 14. Then, the threaded column 16 is pulled towards the connecting plate 20. When the threaded column 16 moves, it rotates through the connecting shaft 15. When the threaded column 16 rotates to the inside of the connecting plate 20 and can no longer rotate, the threaded sleeve 17 can be tightened, so that the threaded sleeve 17 slides through the threaded column 16 and squeezes and fixes the connecting plate 20, thereby installing and fixing the plug rod 19 and the baffle 18.

[0027] See Figure 1 , Figure 2 and Figure 5It can be seen that the baffle 18 can cover the top of the box 1 to prevent rainwater and snow from accumulating on the top of the box 1, thereby avoiding heat loss inside the box 1 and ensuring the heat exchange efficiency of this utility model.

[0028] In summary, when using this utility model, when the electric push rod 10 is running, its end drives the first rack 11 to move away from the support frame 5. When the first rack 11 moves, it drives the large gear 8 to move through meshing. When the large gear 8 moves, it rotates through the connecting rod 7. The arc-shaped support seat 13 can provide auxiliary support for the pipe, and at the same time facilitate the connection between the pipe and both ends of the box 1 without the need for manual support by the staff. This allows for quick connection and fixation of the pipe, thereby improving the safety of pipe connection and reducing labor intensity. The baffle 18 can cover the top of the box 1 to prevent rainwater and snow from accumulating on the top of the box 1, thereby avoiding heat loss inside the box 1 and ensuring the heat exchange efficiency of this utility model.
