Description

Technical Field

[0001] This utility model applies to the field of building engineering technology, and in particular relates to a device for removing scale from building heating and ventilation pipes. Background Technology

[0002] Currently, after prolonged use, building heating and ventilation pipes will accumulate scale on their inner walls. Most of this scale consists of minerals containing calcium and magnesium, which have strong hardness and adhesion. Excessive scale can cause blockages in heating and ventilation pipes or reduce water flow, affecting heating performance. Therefore, construction workers need to regularly remove the scale from the inner walls of the heating and ventilation pipes.

[0003] However, currently, when cleaning scale from HVAC pipes of different diameters, it is not possible to quickly and conveniently adjust the appropriate size of the cleaning tools. This results in scale removal being limited to cleaning only one direction inside the pipe, preventing comprehensive cleaning of the pipe's inner wall. This increases the time required for scale removal and affects the normal operation of HVAC pipes. Therefore, we propose a scale removal device for building HVAC pipes. Utility Model Content

[0004] The main purpose of this utility model is to provide a scale removal device for building heating and ventilation pipes, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A scale removal device for building heating and ventilation pipes includes a fixed frame, a transmission frame fixedly installed on the side of the fixed frame, and a fixed sleeve fixedly installed at the middle of the side of the fixed frame, and the side of the fixed sleeve is rotatably installed inside the transmission frame through a bearing.

[0007] A collection tube is fixedly installed inside the fixed frame, and an infusion tube is fixedly installed inside the fixed sleeve. The side of the infusion tube is fixedly connected to the collection tube, and a rotary joint is fixedly connected to the other side of the infusion tube. An inlet tube is fixedly connected to the side of the rotary joint.

[0008] The fixed frame is provided with multiple sets of striking mechanisms on its side, and the liquid collection pipe is provided with a spraying mechanism on its outer side.

[0009] By adopting the above technical solution, the scale adhering to the inner wall of HVAC pipes can be knocked off by the impact mechanism and the spraying mechanism. At the same time, the operator can adjust the impact radius of the hammer head by controlling the speed of the servo motor, ensuring that the hammer head can be used to clean scale in HVAC pipes of different radii, thereby improving the overall cleaning applicability and scale cleaning efficiency of the mechanism.

[0010] As an optional solution to the technical solution of this application, the striking mechanism includes a striking hammer head, and support plates are fixedly installed on all four sides of the fixed frame. The number of support plates is several sets. An I-shaped rod is rotatably installed between the sides of every two sets of support plates through a bearing. A transmission plate is fixedly sleeved on the outer surface of the middle end of each I-shaped rod. A striking hammer head is fixedly installed on the top side of each transmission plate. A reset torsion spring is movably sleeved on both sides of the outer side of each I-shaped rod.

[0011] By adopting the above technical solution, the hammer head is rotatably installed on the outside of the fixed frame through the I-shaped rod. Combined with the structural action of the reset torsion spring, after the fixed frame is driven by the servo motor to rotate, under the action of centrifugal force, multiple sets of transmission plates located on the outside of the fixed frame can rotate outward synchronously, so that the transmission plates can drive the hammer head to tilt and move away from the outside of the fixed frame synchronously.

[0012] As an optional solution to the technical solution of this application, the spraying mechanism includes a drain spray pipe, and the drain spray pipe is fixedly connected to all four sides of the outer side of the collection pipe, and the side of the drain spray pipe is fixedly connected to the outside of the fixed frame.

[0013] By adopting the above technical solution, the cleaning water can be sprayed out from inside the fixed frame through the connection of the drain spray pipe.

[0014] As an optional solution to the technical solution of this application, a rotating rod is rotatably mounted on the inner side of the transmission frame via a bearing. A transmission gear is fixedly sleeved at the middle end of the rotating rod. A follower gear is fixedly sleeved on the outer side of the fixed sleeve, and the transmission gear and the follower gear mesh with each other. A servo motor is fixedly mounted on the outer side of the transmission frame, and the side of the servo motor transmission shaft is fixedly connected to the outer side of the rotating rod via a coupling.

[0015] By adopting the above technical solution, the servo motor can drive the fixed sleeve and fixed frame to rotate synchronously when the servo motor is running, through the meshing transmission action of the transmission gear and the follower gear, thereby providing driving force for cleaning the scale attached to the inner wall of the HVAC pipe.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present application discloses a scale removal device for building HVAC pipes. This device comprises multiple sets of support plates on the outside of a fixed frame, and transmission plates rotatably mounted between the sides of the support plates via rotating rods. When the fixed frame rotates under the drive of a servo motor, the multiple sets of transmission plates on the outside of the fixed frame rotate synchronously outwards under centrifugal force. This allows the transmission plates to simultaneously tilt and detach the hammer heads from the outside of the fixed frame, rotating synchronously with the frame's rotation. This allows for the removal of scale adhering to the inner wall of the HVAC pipes. Furthermore, the operator can adjust the hammer head's striking radius by controlling the servo motor's speed, ensuring the hammer heads can be used to clean scale from HVAC pipes of different radii, thus improving the overall cleaning applicability and efficiency of the device.

[0018] 2. The scale removal device for building HVAC pipes according to the present application has a liquid collection pipe installed inside a fixed frame and multiple sets of drainage nozzles installed on the side of the liquid collection pipe. The liquid delivery pipe and the liquid inlet pipe are connected by a rotary joint. When the fixed frame rotates, it drives the liquid collection pipe and the drainage nozzles to rotate synchronously. The external cleaning liquid can still be delivered to the inside of the liquid collection pipe through the liquid inlet pipe and then sprayed out into the HVAC pipe. The scale that has been knocked off inside the pipe is carried out of the HVAC pipe with the flow of water, which further improves the operator's efficiency in cleaning scale inside the HVAC pipe.

Detailed Implementation

[0024] like Figure 1-4 As shown, this utility model provides a technical solution: a scale removal device for building HVAC pipes, wherein a transmission frame 3 is fixedly installed on the side of a fixed frame 1, a fixed sleeve 31 is fixedly installed at the middle of the side of the fixed frame 1, and the side of the fixed sleeve 31 is rotatably installed inside the transmission frame 3 via a bearing, a liquid collection pipe 26 is fixedly installed inside the fixed frame 1, a liquid delivery pipe 25 is fixedly installed inside the fixed sleeve 31, and the side of the liquid delivery pipe 25 is fixedly connected to the liquid collection pipe 26, and a rotary joint 28 is fixedly connected to the other side of the liquid delivery pipe 25, and an inlet pipe 29 is fixedly connected to the side of the rotary joint 28.

[0025] In this technical solution (through Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a spraying mechanism is provided on the outside of the liquid collection pipe 26. The spraying mechanism includes a drain spray pipe 27. The drain spray pipe 27 is fixedly connected to all four sides of the outside of the liquid collection pipe 26, and the side of the drain spray pipe 27 is fixedly connected to the outside of the fixed frame 1.

[0026] In this technical solution (through Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a rotating rod 32 is rotatably mounted on the inner side of the transmission frame 3 via a bearing. A transmission gear 33 is fixedly sleeved at the middle end of the rotating rod 32. A follower gear 34 is fixedly sleeved on the outer side of the fixed sleeve 31, and the transmission gear 33 and the follower gear 34 mesh with each other. A servo motor 35 is fixedly mounted on the outer side of the transmission frame 3, and the transmission shaft side of the servo motor 35 is fixedly connected to the outer side of the rotating rod 32 via a coupling.

[0027] In this technical solution (through Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown), the fixed frame 1 is provided with multiple sets of striking mechanisms on its side. The striking mechanism includes a hammer head 23. Support plates 2 are fixedly installed on all four sides of the fixed frame 1. There are several sets of support plates 2. I-shaped rods 21 are rotatably installed between the sides of every two sets of support plates 2 through bearings. A transmission plate 22 is fixedly sleeved on the outer surface of the middle end of each I-shaped rod 21. A hammer head 23 is fixedly installed on the top of the side of each transmission plate 22.

[0028] In some technical solutions (through Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown), each I-shaped rod 21 has a reset torsion spring 24 movably sleeved on both sides of its outer side.

[0029] During operation, the fixed frame 1 is inserted into the HVAC pipe to be cleaned of scale. Cleaning water is then pressurized by a water pump and delivered to the inlet pipe 29. Through the connection between the inlet pipe 29 and the delivery pipe 25, the cleaning water is delivered to the collection pipe 26 and then simultaneously sprayed into the HVAC pipe through the drain spray pipe 27. Simultaneously, the servo motor 35 is activated by an external controller, and its speed is adjusted. This causes the rotating rod 32 to drive the transmission gear 33 to rotate synchronously inside the transmission frame 3. The meshing of the transmission gear 33 and the follower gear 34 drives the fixed sleeve 31 and the fixed frame 1 to rotate synchronously. During the rotation of the fixed frame 1... Under the action of centrifugal force, the multiple sets of transmission plates 22 located on the outside of the fixed frame 1 can rotate outward synchronously. This allows the transmission plates 22 to drive the hammer head 23 to tilt away from the outside of the fixed frame 1. Simultaneously, as the fixed frame 1 rotates, the hammer head 23 contacts the inner wall of the HVAC pipe, thereby knocking off the scale adhering to the inner wall of the HVAC pipe. Then, during the flow of cleaning water, the scale that has been removed is discharged from the inside of the HVAC pipe. After the scale is cleaned, the operation of the servo motor 35 is stopped. Combined with the restoring torsion action of the reset torsion spring 24, the hammer head 23 can be driven to return to its original position and re-attach to the outside of the fixed frame 1 for easy reuse.
