Description

Technical Field

[0001] This invention relates to the field of pipeline technology, specifically to a pipeline for centralized heating and ventilation systems. Background Technology

[0002] Heating, ventilation, and air conditioning (HVAC) is a component of a building, encompassing three aspects: heating, ventilation, and air conditioning. The main functions of HVAC include heating, ventilation, and air conditioning. The term HVAC is a combination of these three functions.

[0003] HVAC (Heating, Ventilation, and Air Conditioning) is a type of central air conditioning system where each household is individually equipped with a system. Central air conditioning systems are further divided into water systems and Freon systems. A typical household split-type Freon air conditioner can only solve the heating and cooling problem, but it cannot handle the air handling process. Centralized HVAC heating provides heating to the room in a centralized manner, which helps to save energy. Centralized HVAC heating requires the use of heating pipes to transport the heat flow and help heat the room. However, after prolonged use, dirt or dust can easily accumulate in the heating pipes. This accumulation can cause blockages, affecting the normal use of the heating system.

[0004] Therefore, we propose a type of pipe for centralized heating and ventilation systems. Summary of the Invention

[0005] In view of the problems existing in the above and / or existing HVAC central heating pipes, the present invention is proposed.

[0006] Therefore, the purpose of this invention is to provide a heating and ventilation centralized heating pipe. By adding a dredging mechanism inside the heating pipe, the problem that dirt or dust easily accumulates in the heating pipe after long-term use can be solved. The accumulation of dirt or dust in the heating pipe can easily cause blockage, which will affect the normal use of the heating pipe.

[0035] The working principle of this invention is as follows: During use, the main pipe body 1 is installed at the desired location, with both ends connected to the pipes to be connected. This helps to limit the movement of the main pipe body 1 and its components, facilitating stable use of the main pipe body 1 and its components. After installation, the pipe is further used through a heating and ventilation system. The heating system delivers heat to the desired location via this pipe. After prolonged use, the main pipe body... Dirt or dust easily adheres to the inside of the pipe body 1. After dirt or dust adheres to the inside of the pipe body 1, it is easy to accumulate. After dirt or dust accumulates on the inner ring surface of the pipe body 1, it will affect or block the inside of the pipe body 1, affecting the normal use of the pipe body 1. It is not conducive to the normal use of the pipe body 1. Further opening the rotating motor 4 on the mounting plate 2, the pipe body 1 can support and limit the mounting plate 2 through the mounting block 3, which facilitates the stable use of the mounting plate 2. The mounting plate 2 can support and limit the rotating motor 4, which helps to stabilize the use of the rotating motor 4.

[0036] With the rotating motor 4 in the open state, the output end of the rotating motor 4 can drive the first rotating rod 5 to rotate. When the first rotating rod 5 rotates, it can drive the first connecting rod 8 to rotate along the corresponding position on the first limiting plate 19. The pipe body 1 can limit the first connecting rod 8 through the first limiting plate 19, which facilitates the stable rotation of the first connecting rod 8. When the first connecting rod 8 rotates, it can drive the first fixing ring 21 to rotate. During the rotation of the first fixing ring 21, it can drive the first connecting block 17 to rotate. When the first connecting block 17 rotates, it can drive the first rotating ring 23 to rotate. When the first rotating ring 23 rotates, it can drive the first fixing plate 25. During the rotation of the first fixing plate 25... The first brush 27 can rotate along the corresponding position on the inner ring surface of the pipe body 1. When the first brush 27 rotates along the corresponding position on the inner ring surface of the pipe body 1, it can clean the corresponding position on the inner ring surface of the pipe body 1. When the first rotating rod 5 rotates, it can drive the first gear 10 to rotate. When the first gear 10 rotates, it can drive the meshing second gear 11 to rotate. When the second gear 11 rotates, it can drive the third rotating rod 7 to rotate along the corresponding positions on the mounting block 3, the first limiting block 14 and the second limiting block 15. The pipe body 1 can limit the third rotating rod 7 through the mounting block 3, the first limiting block 14 and the second limiting block 15, which helps to stably rotate the third rotating rod 7.

[0037] When the third rotating rod 7 rotates, it drives the third gear 12 to rotate. When the third gear 12 rotates, it drives the meshing fourth gear 13 to rotate. When the fourth gear 13 rotates, it drives the second rotating rod 6 to rotate along the mounting plate 2. The mounting plate 2 can limit the rotation of the second rotating rod 6, which helps to stabilize the rotation of the second rotating rod 6. When the second rotating rod 6 rotates, it drives the second connecting rod 9 to rotate along the corresponding position on the second limiting plate 20. The pipe body 1 can limit the second connecting rod 9 through the second limiting plate 20, which helps to stabilize the second connecting rod 9. When rod 9 rotates, it drives the second fixed ring 22 to rotate. When the second fixed ring 22 rotates, it drives the second connecting block 18 to rotate. When the second connecting block 18 rotates, it drives the second rotating ring 24 to rotate. When the second rotating ring 24 rotates, it drives the second fixed plate 26 to rotate. When the second fixed plate 26 rotates, it drives the second brush 28 to rotate along the corresponding position of the inner ring surface of the pipe body 1. When the second brush 28 rotates along the corresponding position of the inner ring surface of the pipe body 1, it can clean the corresponding position of the inner ring surface of the pipe body 1.

[0038] When the first rotating rod 5 rotates, it drives the exhaust fan 16 to rotate. When the exhaust fan 16 rotates, it can draw in the gas and form an airflow. The airflow formed by the exhaust fan 16 can transport the debris or dust cleaned by the first brush 27 and the second brush 28 inside the pipe body 1, so as to discharge the debris or dust cleaned by the first brush 27 and the second brush 28 inside the pipe body 1. During use, it is convenient to clean the dirt or dust inside the pipe body 1, and avoid the accumulation of dirt or dust inside the pipe body 1 after long-term use. It can prevent the accumulation of dirt or dust inside the pipe body 1 from affecting the use, and help prevent blockage inside the pipe body 1, so as to facilitate normal use of the pipe body 1.

[0039] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
