Description

Technical Field

[0001] This utility model relates to the field of ventilation ducts, and in particular to a duct regulating device for heating and ventilation. Background Technology

[0002] Heating and ventilation ducts play a vital role in heating and ventilation systems. In ventilation systems, ducts are used to transport air, delivering fresh air into the room while expelling stale air. By adjusting the air volume within the ducts, the airflow speed and flow rate are controlled to meet the ventilation needs of different areas. By adjusting the flow rate of hot water or steam within the ducts, the distribution of heat is controlled to ensure uniformity and comfort of indoor temperature.

[0003] A search revealed that Chinese Patent Publication No. CN220436707U discloses a pipe adjustment device for heating and ventilation. By starting a motor, the rotating shaft at the bottom of the motor drives a rotating rod to rotate, causing the driving gear and driven gear to mesh. The driven gear drives the rotating shaft to rotate, which in turn drives the baffle plate to rotate. The larger the overlap area between the ventilation hole 2 and the ventilation hole 1, the greater the ventilation volume; the smaller the overlap area between the ventilation hole 2 and the ventilation hole 1, the smaller the ventilation volume, thus achieving the effect of adjusting the ventilation volume.

[0004] In the above technical solution, the air volume is adjusted by the cooperation of the motor-controlled lever and the driving wheel. However, the adjustment device and the ventilation duct are set as one unit. The duct is usually installed at a high place. When the adjustment device is repaired or maintained, it is difficult to quickly separate it from the duct, which will cause inconvenience in operation and increase the difficulty and cost of maintenance. Therefore, a duct adjustment device for heating and ventilation is proposed to solve the above problems. Utility Model Content

A guide vane 12 is fixedly connected to the outer wall. A rotating rod 14 is rotatably connected to the outer wall of the guide vane 12. A lifting frame 13 is rotatably connected to the outer wall of the rotating rod 14. The lifting frame 13 is arranged in an inverted U-shape. The lifting degree of the lifting frame 13 is controlled by a PLC controller with a pre-set electric push rod 15, which switches the degree of closure between the guide vanes 12. An electric push rod 15 is fixedly connected to the top of the lifting frame 13. The fixed end of the electric push rod 15 is fixedly connected to the top of the mounting tube 2. A notch 3 is fitted onto the outer wall of the electric push rod 15.

[0035] Reference Figures 1-3The outer wall of the installation pipe 2 is provided with an embedding groove 4. Embedding grooves 4 are provided on both the upper and lower sides of the installation pipe 2. When the embedding groove 4 is located in the notch 3, it facilitates the operator's access to the dial ring 6. A double-acting screw 5 is rotatably connected to the inner wall of the embedding groove 4. The dial ring 6 is fixedly connected to the outer wall of the double-acting screw 5. A plug rod 7 is threadedly connected to the outer wall of the double-acting screw 5. The plug rod 7 is arranged in an inverted L-shape. One end of the outer wall of the plug rod 7 fits against the inner wall of the embedding groove 4 and is slidably connected to the embedding groove 4. A slot 8 is provided on the inner wall of the pipe body 1. The other end of the outer wall of the plug rod 7 is slidably connected to the inner wall of the slot 8. The installation tube 2 has a T-slot 10, and a T-block 9 is fixedly connected to the outer wall of the installation tube 2. The outer wall of the T-block 9 is adapted to the inner wall of the T-slot 10. By embedding the T-block 9 into the T-slot 10, the installation tube 2 can be quickly positioned between itself and the pipe body 1. A filter frame 17 is provided inside the installation tube 2. The top of the filter frame 17 has two sets of recesses for easy insertion and force application by hand. A filter screen 18 is fixedly connected to the inner wall of the filter frame 17. The filter screen 18 can intercept impurities in the air and improve ventilation. A fixing component is provided on the surface of the installation tube 2 for fixing the installation tube 2.

[0036] Reference Figures 4-6 The fixing component includes a slot 16, which is located at the top of the mounting tube 2. The inner wall of the slot 16 is adapted to the outer wall of the filter frame 17. The slot 16 facilitates the removal of the filter frame 17 from the mounting tube 2. A fixing groove 19 is provided at the bottom of the filter frame 17. A magnetic sheet 20 is fixedly connected to the inner wall of the fixing groove 19. A magnetic sheet 21 is magnetically connected to the bottom of the magnetic sheet 20. The bottom of the magnetic sheet 21 is fixedly connected to the inner wall of the mounting tube 2. The outer wall of the magnetic sheet 21 is adapted to the inner wall of the fixing groove 19. By embedding the magnetic sheet 21 into the fixing groove 19 and generating magnetism with the magnetic sheet 20, the filter frame 17 can be limited, enabling the filter frame 17 to be quickly replaced.

[0037] Reference Figure 4 The bottom of the pipe body 1 is rotatably connected to a movable shaft 22, and the bottom of the movable shaft 22 is fixedly connected to a support frame 23. The inner wall of the support frame 23 is threadedly connected to a screw 24. The bottom of the mounting pipe 2 is provided with a fixing hole 25. The inner wall of the fixing hole 25 is adapted to the outer wall of the screw 24. The internal thread on the surface of the screw 24 allows it to be inserted into the fixing hole 25 without obstruction. The fixing hole 25 is located on the side of the center of the mounting pipe 2 near the guide vane 12. The bottom of the pipe body 1 is provided with a screw hole 26. The inner wall of the screw hole 26 is threadedly connected to the outer wall of the screw 24. After the screw hole 26 is connected to the screw 24, the support frame 23 can be stored at the bottom of the pipe body 1.

[0038] Working principle: Align the T-block 9 with the T-slot 10 and insert it. Push the installation tube 2 to embed it into the pipe body 1. When the installation tube 2 can no longer be pushed, the pipe body 1 and the opening of the installation tube 2 are parallel. At this time, turn the two sets of dial rings 6 in sequence. The dial rings 6 control the rotation of the bidirectional screw 5 to make the two sets of insertion rods 7 move away from each other until they are inserted into the two sets of corresponding slots 8, fixing the installation tube 2. After the electric push rod 15 is powered on, it starts to lift and lower to a predetermined position, causing the lifting frame 13 to tilt multiple sets of guide vanes 12, thereby adjusting the wind force. When the filter screen 18 needs to be replaced, manually reverse the dial rings 6 in sequence to disengage the two sets of insertion rods 7 from the slots 8, and then reverse the screw 24 to disengage it from the screw hole 26. Manually hold the tube of the installation tube 2. The wall pulls it out of the pipe body 1. When the slot 16 is completely outside the pipe opening of the pipe body 1, the support frame 23 is moved to position so that the screw 24 and the fixing hole 25 are kept horizontal. The screw 24 is rotated to embed it into the fixing hole 25 to support the area where the installation pipe 2 extends outside the pipe body 1. The filter frame 17 is manually inserted into the concave part and force is applied to it. After the filter frame 17 moves out along the slot 16, it is convenient to replace or clean it. After the filter screen 18 is replaced or cleaned, the filter frame 17 is inserted along the slot 16 until the magnetic plate 21 is embedded in the fixing groove 19 and magnetically attracts the magnetic plate 20. The above steps are reversed so that the installation pipe 2 enters the pipe body 1, which facilitates the adjustment of the air volume and the quick replacement of the filter screen 18.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
