Description

Technical Field

[0001] This utility model relates to the field of chimney technology, specifically to an adjustable-height prefabricated chimney structure. Background Technology

[0002] A chimney is a structure that provides ventilation for hot flue gas or smoke from a boiler or factory. Chimneys are typically vertical, or as close to vertical as possible, to ensure a smooth flow of gas, drawing in air for combustion, or the chimney effect. The space inside the chimney is called a flue.

[0003] In existing technologies, during the manufacturing process in a factory, a certain amount of industrial waste gas is generated in the factory building. Therefore, a chimney is installed on the roof of the factory building to collect the waste gas and discharge it at high altitude. The height of the chimney is used to make the waste gas rise to the upper atmosphere, and the ground pollutant concentration is reduced by air diffusion and dilution, thus avoiding the waste gas from lingering and accumulating in the factory building. However, when exhausting gas through chimneys, some factories use prefabricated chimneys. This means that when increasing the height of the chimney, two chimneys need to be installed in a docking manner to increase the height of the chimney. This kind of increase is fixed. If the chimney is too high, the chimney effect may be too strong, causing turbulent airflow at the top and backflow in strong winds, which will reduce the exhaust efficiency. To address this, we propose a prefabricated chimney structure with adjustable height. Utility Model Content

[0007] In some embodiments, a wind deflector is provided at the top of the inner tube, the top of the inner tube is in contact with the bottom of the wind deflector, and the outer side of the wind deflector is connected through the inner wall of the rain cover.

[0008] In some embodiments, a throttle is provided on one side of the outer ring, and one side of the outer ring is fixedly connected to one end of the throttle. A convex ring is provided on the top inner wall of the throttle, and the top inner wall of the throttle is rotatably engaged with the bottom protrusion of the convex ring.

[0009] In some embodiments, a protective cover is provided on the outer side of the convex ring, the outer side of the convex ring is in perpendicular sliding contact with the inner side of the protective cover, a sub-rod is provided on the inner wall of the protective cover, the inner wall of the protective cover is slidably connected to the outer side of the sub-rod, and the bottom end of the sub-rod is fixedly connected to the top side of the convex ring.

[0010] In some embodiments, a mother tube is provided on the outer side of the top end of the sub-rod, the outer side of the top end of the sub-rod is slidably connected vertically to the inside of the mother tube, a spring is provided inside the mother tube, the top end of the spring is fixedly connected to the inside of the mother tube, and the bottom end of the spring is fixedly connected to the top end of the sub-rod.

[0013] This utility model has at least the following beneficial effects: 1. By pushing the handle with external force, the outer ring and the inner ring rotate synchronously. The outer ring rotates on the outside of the chimney body, and the inner ring rotates on the inside of the chimney body. During this process, the extrusion plate uses the inclined surface to create an upward external force on the connecting rod, which in turn changes the position of the inner tube on the chimney body, thereby increasing its height. This allows for flexible adjustment of the overall height of the chimney to adapt to different exhaust requirements. 2. When the throttle is turned, the convex ring uses the elasticity of the spring to continuously engage with the throttle in an undulating manner. After the throttle is turned to the desired position, the spring force forms a mechanical lock to prevent the throttle from rotating on its own due to external force. Finally, the rotation of the lead screw causes the arc plate to move and enter the groove of the sub-rod, ensuring the stability of the throttle after locking and further improving the structural reliability after the chimney height is adjusted.

An inner ring 15 is provided at the bottom end of the extrusion plate 14, and the bottom end of the extrusion plate 14 is fixedly connected to the top side of the inner ring 15. An outer ring 16 is provided on one side of the inner ring 15, and one side of the inner ring 15 is fixedly connected to one inner end of the outer ring 16. A handle 17 is provided on one side of the outer ring 16, and one side of the outer ring 16 is fixedly connected to one end of the handle 17. A protruding ring 18 is provided on the top inner wall of the handle 17, and the top inner wall of the handle 17 rotatably engages with the protruding part on the bottom side of the protruding ring 18. A protective cover 19 is provided on the outer side of the protruding ring 18. The inner wall of the cover 19 is provided with a sub-rod 110, which is slidably connected to the outer side of the sub-rod 110. The bottom end of the sub-rod 110 is fixedly connected to the top side of the protruding ring 18. The outer side of the top end of the sub-rod 110 is provided with a mother tube 111, which is slidably connected to the inside of the mother tube 111. The inside of the mother tube 111 is provided with a spring 112, which is fixedly connected to the top end of the spring 112. The bottom end of the spring 112 is fixedly connected to the top end of the sub-rod 110. An arc-shaped plate 113 is provided in a recessed part on one side of the sub-rod 110. The recessed part on one side of the sub-rod 110 is slidably engaged with the outer side of the arc-shaped plate 113. A guide rod 114 is provided on the inner wall of the arc-shaped plate 113. The inner wall of the arc-shaped plate 113 is slidably connected to the outer side of the guide rod 114. One end of the guide rod 114 is fixedly connected to one side of the chimney body 11. A screw rod 115 is provided at the middle of one side of the chimney body 11. The middle of one side of the chimney body 11 is rotatably connected to one end of the screw rod 115. The outer side of the screw rod 115 is threadedly rotatably connected to the inner wall of the arc-shaped plate 113.

[0017] In use, this type of adjustable-height prefabricated chimney structure firstly involves a chimney body 11 with an inner tube 12 designed inside. The inner tube 12 is vertically connected to the chimney body 11 in a fitting manner. Simultaneously, three connecting rods 13 are fixed to the bottom end of the inner tube 12. The bottom ends of all three connecting rods 13 contact the top side of an inner ring 15. The top side of the inner ring 15 is designed with three arc-shaped extrusion plates 14, which are triangular in shape. Furthermore, to allow for the adjustment of the chimney body 11's height as needed, therefore... An outer ring 16 is connected to one side of the inner ring 15, and a handle 17 is fixed to one side of the outer ring 16. By pushing the handle 17 with external force, the outer ring 16 and the inner ring 15 rotate synchronously. The rotation is such that the outer ring 16 rotates on the outside of the chimney body 11, and the inner ring 15 rotates on the inside of the chimney body 11. During this process, the extrusion plate 14 uses the inclined surface to create an upward external force on the connecting rod 13, thereby changing the position of the inner tube 12 on the chimney body 11, raising its height on the original basis, thus realizing the flexible adjustment of the overall height of the chimney to adapt to different exhaust needs. A protective cover 19 is designed on the outside of the chimney body 11, and a protruding ring 18 is installed on the inside of the protective cover 19. Multiple protrusions are designed along the circumferential direction on the bottom side of the protruding ring 18. The protrusions fit into the recesses in the inner wall of the throttle handle 17. A sub-rod 110 is connected to the top side of the protruding ring 18. The sub-rod 110 is located inside the main tube 111. The sub-rod 110 and the main tube 111 are connected by a spring 112. In this way, when the throttle handle 17 rotates along the chimney body 11, the elasticity of the spring 112 causes the protruding ring 18 to continuously engage with the throttle handle 17 in an undulating manner. After the throttle handle 17 is rotated to the desired position, the elasticity of the spring 112 forms a mechanical lock to prevent the throttle handle 17 from rotating on its own due to external force, thus ensuring the stability of the height position of the inner tube 12 after adjustment. By designing guide rods 114 on one side of the chimney body 11, there are two guide rods 114 located on the inner walls of both ends of the arc plate 113. At the same time, a lead screw 115 is installed on the inner wall of the middle end of the arc plate 113. Therefore, the rotation of the lead screw 115 causes the arc plate 113 to move, gradually entering the groove of the sub-rod 110, thus restricting the sub-rod 110 and preventing the elastic force of the spring 112 from causing the engagement between the convex ring 18 and the handle 17 to fail due to vibration. This ensures the stability of the handle 17 after locking, further improving the structural reliability after the chimney height is adjusted. Furthermore, under the action of the guide rods 114, the arc plate 113 can move along a prescribed path when sliding, ensuring that it can accurately enter the groove of the sub-rod 110.

[0018] Example 2: Please refer to Figure 1 - Figure 7The protective mechanism 2 includes a rain cover 21. A rod 22 is provided on the bottom side of the rain cover 21. The bottom side of the rain cover 21 is fixedly connected to the top of the rod 22. The outer side of the bottom end of the rod 22 fits and engages with the inner wall of the top end of the inner tube 12. A wind deflector 23 is provided on the top end of the inner tube 12. The top end of the inner tube 12 contacts the bottom end of the wind deflector 23. The outer side of the wind deflector 23 is connected through to the inner wall of the rain cover 21.

[0019] An insert rod 22 is designed on the inner wall of the top of the inner tube 12. The two are connected by a snap-fit ​​connection. At the same time, a rain cover 21 is fixed at the top of the insert rod 22. The rain cover 21 is conical and is located vertically above the top of the inner tube 12. The conical curved surface guides rainwater to flow in all directions, preventing rainwater from directly entering the inner tube 12. At the same time, four arc-shaped grooves are opened along the circumference of the rain cover 21. The wind deflector 23 can be inserted into the arc-shaped grooves according to the wind direction, so that the wind deflector 23 can be flexibly adjusted to the windward direction. The physical blocking reduces the interference of lateral wind force on the exhaust airflow and improves the exhaust stability of the chimney in strong wind environment.

[0020] Please see Figure 1 - Figure 7 By applying external force to the throttle 17, the outer ring 16 and the inner ring 15 rotate synchronously. The outer ring 16 rotates on the outside of the chimney body 11, while the inner ring 15 rotates on the inside of the chimney body 11. During this process, the pressure plate 14 uses its inclined surface to create an upward external force on the connecting rod 13, thereby changing the position of the inner tube 12 on the chimney body 11, raising its height from its original position. After the height increase, there are multiple protrusions on the bottom side of the convex ring 18, and these protrusions interact with the concave areas in the inner wall of the throttle 17. The recess fits snugly, and the top side of the protruding ring 18 is connected to the sub-rod 110. The sub-rod 110 is located inside the main tube 111. The sub-rod 110 and the main tube 111 are connected by a spring 112. In this way, when the handle 17 rotates along the chimney body 11, the elasticity of the spring 112 causes the protruding ring 18 to continuously engage with the handle 17 in an undulating manner, thereby fixing the handle 17 after it is turned to the desired position, while restricting the inner tube 12 to prevent the position from changing due to the instability of the handle 17. By snapping the plug 22 into the empty pipe, and since the top of the plug 22 has a rain cover 21, which is located vertically above the top of the inner pipe 12, rainwater is prevented from directly entering the inner pipe 12. At the same time, four arc-shaped grooves are opened along the circumference of the rain cover 21, so that the wind deflector 23 can be inserted into the arc-shaped grooves according to the wind direction, allowing the wind deflector 23 to be flexibly adjusted to the windward direction.
