Description

Technical Field

[0001] This utility model relates to the field of air duct technology, specifically an air duct with heat insulation function. Background Technology

[0002] Air ducts are piping systems used for air transport and distribution. There are two types: composite air ducts and inorganic air ducts. Composite air ducts are the most representative.

Stainless steel air duct fabrication involves applying sealant to gaps such as seams, rivet seams, and the four corners of flanges. Before applying sealant, surface dust and oil should be removed. According to cross-sectional shape, air ducts can be divided into various types such as circular air ducts, rectangular air ducts, and flat oval air ducts. Traditional air ducts are mostly fixed connections, and insulation cotton is often wrapped around the outer wall of the air duct to achieve the function of heat preservation. However, the air outlet position is not convenient for adjustment. Therefore, in order to better adjust the air outlet of the air duct, an air duct with heat preservation function has been proposed.

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] Please see Figure 1-5 This utility model provides an embodiment of a heat-insulating duct, comprising a top plate 1 and a duct body 3. Two sets of duct bodies 3 are disposed below the top plate 1, and the two sets of duct bodies 3 converge into a single duct. A mounting bracket 2 is installed at the bottom end of the top plate 1, and the mounting bracket 2 is connected to the duct body 3. A support plate 4 is installed at the bottom end of the top plate 1 on one side of the mounting bracket 2. A corrugated pipe 6 is fitted onto the surface of the duct body 3, and a clamp 7 is fitted onto the surface of the corrugated pipe 6. A flexible hose 5 is installed inside the corrugated pipe 6. A servo motor 8 is installed at the top of the support plate 4. The servo motor 8 serves as the power drive. A rotary disk 9 is installed at the output end of the servo motor 8. A reciprocating rod 10 is installed at the bottom end of the rotary disk 9. A rotating block 11 is movably installed at the bottom end of the support plate 4 on one side of the rotary disk 9. The reciprocating rod 10 is slidably connected to the rotating block 11. A swing rod 12 is slidably installed at the bottom end of the support plate 4 on one side of the rotating block 11. The rotating block 11 and the swing rod 12 mesh with each other. A connecting rod 13 is installed at the bottom end of the swing rod 12. A connecting ring 14 is installed at the bottom end of the connecting rod 13. The connecting ring 14 is connected to the flexible hose 5.

[0024] First, the device is installed on the ceiling. Simultaneously, a layer of insulation cotton is wrapped around the outer wall of the duct body 3 to achieve its insulation function. When the airflow direction needs to be changed, the servo motor 8 is turned on, driving the rotating disk 9 to rotate. The rotating disk 9 then drives the reciprocating rod 10 to rotate. Because the reciprocating rod 10 is located at an eccentric position on the side wall of the rotating disk 9, under the sliding engagement between the reciprocating rod 10 and the rotating block 11, and the movable engagement between the rotating block 11 and the support plate 4, the reciprocating rod 10 drives the rotating block 11 to reciprocate on the surface of the support plate 4. Under the mutual meshing of the rotating block 11 and the swing rod 12, the rotating block 11 drives the swing rod 12 to move reciprocally, and the swing rod 12 drives the connecting rod 13 and the connecting ring 1. 4. Reciprocating movement: The flexible hose 5 is driven by the connecting ring 14 to reciprocate, adjusting the direction of airflow. When it is necessary to inspect the interior of a set of duct bodies 3, a set of electric push rods 16 is opened, which drives a set of electric push arms 17 to move. The electric push arms 17 drive a set of L-shaped arms 19 to rotate, which in turn drives a set of linkage shafts 18 and valve plates 20 to rotate, so that the valve plates 20 can close the set of duct bodies 3, thus completing the inspection of the set of duct bodies 3. At the same time, another set of duct bodies 3 undertakes the function of supplying air, realizing convenient reciprocating swing adjustment of the airflow direction, facilitating the inspection of ducts without stopping the machine, and improving the flexibility of use.

[0025] The top of the duct body 3 is equipped with a support frame 15. Two sets of electric push rods 16 are movably installed inside the support frame 15. The electric push rods 16 serve as power drives. Electric push arms 17 are installed at the output ends of the electric push rods 16. L-shaped arms 19 are movably installed at the end of the electric push arms 17 away from the electric push rods 16.

[0026] The L-shaped arm 19 is equipped with a linkage shaft 18 at the end away from the electric push arm 17, and the linkage shaft 18 extends into the interior of the duct body 3.

[0027] The linkage shaft 18 is movably connected to the duct body 3, and valve plates 20 are installed on the surface of the linkage shaft 18. Mounting blocks 21 are installed at both ends of the clamp 7, and bolts 22 are installed inside a set of mounting blocks 21.

[0028] A hinge shaft 26 is installed at one end of the bolt 22, and the bolt 22 is movably connected to a set of mounting blocks 21 through the hinge shaft 26. A clamping block 25 and a locking nut 23 are fitted on the surface of the bolt 22, and the clamping block 25 is slidably connected to the bolt 22, and the locking nut 23 is threadedly connected to the bolt 22. A filter screen 24 is installed inside the duct body 3.

[0029] When the filter screen 24 needs to be disassembled and cleaned, rotate the locking nut 23. Under the threaded connection between the locking nut 23 and the bolt 22, the locking nut 23 is disengaged from the bolt 22. Move the abutment block 25. The abutment block 25 slides on the surface of the bolt 22, moving the abutment block 25 away from a set of mounting blocks 21. Then rotate the bolt 22. The bolt 22 rotates around the hinge shaft 26. The bolt 22 drives the locking nut 23 and the abutment block 25 to rotate, so that the clamp 7 changes from closed to open. Then remove the corrugated pipe 6. The worker can then reach into the inside of the air duct body 3 to disassemble the filter screen 24. This achieves convenient disassembly and cleaning of the filter screen, making it easy to disassemble and clean the filter screen.

[0030] Working Principle: First, the device is installed on the ceiling. Simultaneously, a layer of insulation cotton is wrapped around the outer wall of the duct body 3 to achieve its insulation function. The servo motor 8 drives the rotating disk 9 to rotate, which in turn drives the reciprocating rod 10 to rotate. Because the reciprocating rod 10 is located eccentrically on the side wall of the rotating disk 9, under the sliding cooperation between the reciprocating rod 10 and the rotating block 11, and the movable cooperation between the rotating block 11 and the support plate 4, the reciprocating rod 10 drives the rotating block 11 to reciprocate on the surface of the support plate 4. The rotating block 11 drives the swing rod 12 to reciprocate, which in turn drives the connecting rod 13 and the connecting ring 14 to reciprocate. The connecting ring 14 drives the flexible hose 5 to reciprocate, thus adjusting the direction of the airflow. When it is necessary to inspect the interior of a set of duct bodies 3, the electric push rod 16 drives a set of electric push arms 17 to move, and the electric push arms... 17 drives a set of L-shaped arms 19 to rotate, which in turn drives a set of linkage shafts 18 and valve plates 20 to rotate, so that the valve plates 20 can close the set of duct bodies 3 to complete the maintenance work of the set of duct bodies 3. At the same time, another set of duct bodies 3 undertakes the function of air supply. When the filter screen 24 needs to be disassembled and cleaned, rotate the locking nut 23 to disengage the locking nut 23 from the bolt 22, move the abutment block 25, and slide the abutment block 25 on the surface of the bolt 22 to move the abutment block 25 away from a set of mounting blocks 21. Then rotate the bolt 22, and the bolt 22 rotates around the hinge shaft 26. The bolt 22 drives the locking nut 23 and the abutment block 25 to rotate, so that the clamp 7 changes from closed to open. Then the corrugated pipe 6 can be removed, and the worker can reach into the inside of the duct body 3 to remove the filter screen 24 to complete the use of the duct with heat preservation function.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
