Description

Technical Field

[0001] The invention relates to the technical field of pipelines, and in particular to a high-efficiency ventilation and smoke exhaust pipeline device for heating. Background Art

[0002] HVAC is an integral part of a building, including heating, ventilation and air conditioning. Ventilation and smoke exhaust ducts are used for ventilation and smoke exhaust equipment in building fire protection. Since a building will produce a lot of thick smoke when it catches fire, many people at the fire scene will be suffocated and comatose due to inhaling a lot of thick smoke, thus missing the escape time. Therefore, ventilation and smoke exhaust ducts can play a big role and bear the important responsibility of air circulation and rapid exhaust of thick smoke. Since the air carries particles such as dust and sand, filters are installed in the ducts to effectively intercept particles in the air and prevent these impurities from entering the fans of ventilation and smoke exhaust ducts. Since the filter blocks the particles in the air for a long time, the particles are adsorbed and accumulated on the surface of the filter, causing the filter to be seriously blocked, thereby causing the air circulation of ventilation and smoke exhaust in the duct to be blocked, affecting the smoke exhaust and ventilation speed, and being unable to effectively exhaust smoke, causing excessive smoke inhalation by personnel, reducing the efficiency of ventilation and smoke exhaust in the duct.

[0028] The connection assembly 5 includes a receiving seat 57 fixed in the guide groove 45, a fixing plate 53 fixed to the end of the guide rod 46 away from the movable plate 42, and a receiving frame 54 fixed to the middle of the top of the fixing plate 53. The top of the receiving seat 57 is movably connected with a swing rod 56, and the top of the swing rod 56 is installed with a second contact plate 52. The outer part of the rotating column 22 close to the connecting seat 24 is fixedly sleeved with a first contact plate 51 matched with the second contact plate 52. The bottom of the swing rod 56 is installed with a floating block 58. The top of the receiving frame 54 is provided with a floating groove 55 for the floating block 58 to slide. The guide groove 4 5 is provided with a support assembly 6, and the support assembly 6 is used to drive the fixing plate 53 to quickly move and reset along the guide groove 45; the support assembly 6 includes a limit seat 61 fixed in the guide groove 45, a spring groove 62 provided at one end of the limit seat 61 for the guide rod 46 to be inserted, and a spring ring 64 fixedly sleeved on the outside of the guide rod 46, and the spring ring 64 is located in the spring groove 62, a spring 63 is fixed between the spring ring 64 and the spring groove 62, and the spring 63 is sleeved on the guide rod 46; the top ends of the swing rod 56 and the receiving seat 57 are also provided with a flat groove for the rotating blade 25 to rotate.

[0029] Through the above technical solution: When the cleaning brush 23 rotates to clean the surface of the filter screen 12, the rotating column 22 first rotates to drive the first contact plate 51 to rotate synchronously, and the spring 63 itself can give a push and pull force to one end of the spring ring 64, so that the guide rod 46 can move along the spring groove 62 and cooperate with the fixed plate 53, and the fixed plate 53 moves along the guide groove 45 under the action of the elastic force, so that the movement of the fixed plate 53 can give a reaction force to the receiving frame 54, which is beneficial to the second contact plate 52 and the first contact plate 51. Stable fit, at this time, the first contact plate 51 rotates to rotate it along one side of the second contact plate 52 and contacts the second contact plate 52.

The movement of the second contact plate 52 drives the swing rod 56 to rotate along the receiving seat 57 and drives the floating block 58 to move upward or downward along the floating groove 55. The floating block 58 thus moves upward or downward to form a conflict with the floating groove 55 and push the receiving frame 54 and the fixed plate 53 to move leftward or rightward along the guide groove 45. As the fixed plate 53 moves, the guide rod 46 is pushed to reciprocate along the limit seat 61, the guide groove 45 and the ventilation pipe 11 into the positioning groove 41, and the moving plate 42 moves to move it synchronously along the centering groove 43. As the moving plate 42 moves, the conflicting plate 44 is driven to reciprocate between the filter screen 12 and the cleaning brush 23, and then the conflicting plate 44 can be realized. The plate 44 intersects with the surface of the cleaning brush 23 and maintains friction with the cleaning brush 23, so that the reciprocating movement of the contact plate 44 makes the contact plate 44 intersect with the cleaning brush 23 at different positions, which can more comprehensively cover the surface of the cleaning brush 23, and is used to clean the surface and internal impurities of the cleaning brush 23, ensuring that every corner can be effectively cleaned, which is beneficial for the cleaning brush 23 to keep the surface of the filter 12 clean, reduce the adhesion of particulate matter on the surface of the filter 12, and further improve the ventilation efficiency in the ventilation duct 11.
