Description

Technical Field

[0001] The utility model relates to the technical field of HVAC pipelines, in particular to a device for cleaning scale inside a HVAC pipeline. Background Art

[0002] As we all know, after a long period of use, since HVAC pipes are heated by hot water, the minerals contained in the water will adhere to the inner wall of the pipes after a long period of heating, and scale will gradually form. In order to clean the scale in the pipes, a HVAC pipe internal scale cleaning device is needed.

[0003] The patent with application number CN202121247442.8 discloses a device for cleaning scale inside a HVAC pipe, including a fixed hoop, both ends of the fixed hoop are fixedly connected with fastening heads, a fastening screw is provided between the two fastening heads, and a vibration hoop is provided in the middle of the fixed hoop, a hard vibrating arc block is fixedly connected to the inner surface of the vibration hoop, the two sides of the top of the vibration hoop are connected to the top of the fixed hoop through springs, and an ultrasonic transducer is fixedly connected to the top of the vibration hoop.

[0004] Although the device can fix the fixing clamp on the pipe, the fixing clamp is an integral arrangement, and the opening at the bottom of the fixing clamp is smaller than the diameter of the pipe. The fixing clamp needs to be put on the pipe from the pipe mouth of the pipe, and then slide to a designated position to perform vibration and other work to clean the scale in the pipe, but cannot be directly installed on the corresponding position of the pipe body, so the practicality is not very good. Secondly, when fixing, the device is installed by threading the fastening bolt on the fastening head. This method requires a large number of turns of the fastening bolt to fix the fastening bolt, which takes a long time. Therefore, the practicality is not very good and there is room for improvement.

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides a device for cleaning scale inside a HVAC pipe, which has the following beneficial effects:

[0016] The device for cleaning scale inside the HVAC pipe can open the first clamping ring and the second clamping ring by rotating them. After the unfolded angle is greater than the diameter of the pipe, the device can be directly installed and fixed at any part of the pipe, so there is no need to install it from the pipe mouth. Secondly, when fixing the pipe, the device only needs to tighten the lower parts of the first clamping ring and the second clamping ring, pass through the fixing rod, and then clamp the rotating plate in the aligned groove at the lower part. The leftward reaction force provided by the second clamping plate to the rotating plate and the rotating plate can be fixed in cooperation with the groove, thereby fixing the first clamping ring and the second clamping ring. Compared with the method of tightening the bolts, the time spent on installation is short, and a part of time is saved, thereby improving a certain degree of practicality.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4The utility model discloses a device for cleaning scale inside a heating and ventilation pipe, comprising a first clamping ring 1, a plurality of fixing plates 2 are arranged on the left part of the first clamping ring 1, the plurality of fixing plates 2 are rotatably connected with a connecting rod through a rotating shaft, and a second clamping ring 3 is arranged on the connecting rod. The second clamping ring 3 and the first clamping ring 1 are rotatably arranged, and when the angle between the lower parts of the second clamping ring 3 and the first clamping ring 1 is greater than the diameter of the pipe, the second clamping ring 3 can be directly passed through the pipe body to clamp the pipe, so that it is not necessary to put the pipe on the pipe head and then move the device for cleaning scale inside the heating and ventilation pipe. A gap is arranged between the upper part of the second clamping ring 3 and the plurality of fixing plates 2 to prevent the second clamping ring from being clamped. When the holding ring 3 rotates, it interacts with the fixing plate 2. The upper part of the first clamping ring 1 is provided with a mounting groove 10, and an ultrasonic transducer 11 is installed in the mounting groove 10. The lower part of the ultrasonic transducer 11 is provided with a connecting plate 13, and the lower part of the connecting plate 13 is provided with a vibration plate 12. The ultrasonic transducer 11 is started to generate vibration, which is transmitted to the pipeline through the connecting plate 13 and the vibration plate 12 to clean the internal dirt.
