Description

Technical Field

[0001] This utility model relates to the field of heating, ventilation and air conditioning (HVAC) system technology, and more specifically, to a system for monitoring and removing scale buildup on the inner wall of HVAC water pipes. Background Technology

[0002] Heating, ventilation, and air conditioning (HVAC) water pipes are the conduits through which HVAC media circulate. When hot water flows through these pipes, trace amounts of scale will accumulate. Therefore, it is necessary to monitor factors such as scale thickness online and clean and remove the scale promptly.

[0003] A search revealed that Chinese patent CN219597570U discloses "a system for monitoring and removing scale from the inner wall of HVAC water pipes, including HVAC water pipes, a scale monitoring module, a scale removal module, and a vibration component; clamps are symmetrically installed on the outer side of the HVAC water pipes, with the upper ends of the outer sides of the clamps fixedly connected to the bottom surface of the mounting plate; the left and right ends of the bottom surface of the mounting plate are symmetrically connected to sleeves that mate with the outer side of the HVAC water pipes via pins, and the lower ends of the two corresponding sleeves are fixedly connected by bolts; the scale monitoring module includes an ultrasonic thickness gauge and an ultrasonic probe, with the ultrasonic thickness gauge located on the right side of the upper surface of the mounting plate. This invention can automatically monitor the thickness of scale inside the HVAC water pipes, can periodically and automatically dissolve the scale deposited inside the HVAC water pipes, and simultaneously remove the scale quickly through vibration, resulting in better scale removal." However, it still has the following drawbacks:

[0004] (1) The device uses a vibrating frame to strike the HVAC water pipe to make the HVAC water pipe vibrate, which causes the dissolved scale on the inner wall to fall off. However, frequent striking may cause scratches, dents and other damage to the surface of the HVAC water pipe. Over time, these damages may affect the sealing performance of the HVAC water pipe, leading to problems such as water leakage.

[0005] (2) The monitoring probe of the device is located on the inner wall of the jacket. In actual use, the vibration component will cause continuous vibration when it is working. This vibration will be transmitted to the jacket and the monitoring probe, causing the probe to gradually loosen. To address this, a system for monitoring and removing scale on the inner wall of HVAC water pipes is proposed. Utility Model Content

[0006] The purpose of this invention is to address the problem that current methods of using a vibrating frame to tap HVAC water pipes to vibrate them and remove dissolved scale from the inner wall can cause scratches, dents, and other damage to the surface of the HVAC water pipes.

This invention provides a system for monitoring and removing scale from the inner wall of HVAC water pipes to solve the problems mentioned in the background.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] The present invention is as follows: a system for monitoring and removing scale from the inner wall of a heating and ventilation water pipe, comprising a heating and ventilation water pipe, wherein an auxiliary removal component is provided on the outer wall of the heating and ventilation water pipe to remove scale from the inner wall of the heating and ventilation water pipe by using ultrasonic vibration, a scale monitoring component is provided on the outer wall of the heating and ventilation water pipe to monitor the thickness of scale on the inner wall of the heating and ventilation water pipe, and a scale removal component is provided on one side of the scale monitoring component to remove scale from the inner wall of the heating and ventilation water pipe;

[0011] As a preferred technical solution of this utility model, the scale removal component includes an electronic descaling device fixedly installed on the top of two adjacent sets of clamps. The electronic descaling device is located on one side of the scale thickness monitoring device. A coil is wound around the outer wall of the HVAC water pipe. The coil is located below the electronic descaling device. The electronic descaling device and the coil are fixedly connected by a wire.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. With the auxiliary cleaning component, when in use, the ultrasonic transducer receives a high-frequency electrical signal from the ultrasonic generator and generates high-frequency mechanical vibration.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0028] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] like Figure 1 As shown, this embodiment proposes a system for monitoring and removing scale on the inner wall of a heating and ventilation water pipe 1, including a heating and ventilation water pipe 1. An auxiliary removal component 2 is provided on the outer wall of the heating and ventilation water pipe 1 to remove scale from the inner wall of the heating and ventilation water pipe 1 by generating vibration with ultrasonic waves. A scale monitoring component 3 is provided on the outer wall of the heating and ventilation water pipe 1 to monitor the thickness of scale on the inner wall of the heating and ventilation water pipe 1. A scale removal component 4 is provided on one side of the scale monitoring component 3 to remove scale from the inner wall of the heating and ventilation water pipe 1.

[0031] like Figure 2 , Figure 3 and Figure 6As shown, the auxiliary cleaning component 2 includes a clamp 201 fixedly installed on the outer wall of the HVAC water pipe 1. A first mounting plate 202 is fixedly installed on the clamp 201. An ultrasonic generator 203 is bolted to the first mounting plate 202. An ultrasonic transducer 204 is connected to one side of the ultrasonic generator 203 via an electric wire. A gasket 205 is fixedly installed at the bottom of the ultrasonic transducer 204. The side of the gasket 205 is in contact with the outer wall of the HVAC water pipe 1. When in use, the ultrasonic transducer 204 receives a high-frequency electrical signal from the ultrasonic generator 203 and generates high-frequency mechanical vibration. The high-frequency mechanical vibration will propagate rapidly along the wall of the HVAC water pipe 1 and be transmitted to the water inside the HVAC water pipe 1 and the scale adhering to the inner wall of the HVAC water pipe 1. Under the action of the high-frequency vibration of the ultrasonic waves, the scale will gradually peel off from the inner wall of the HVAC water pipe 1, achieving the purpose of removing scale. It will not cause significant mechanical impact or damage to the HVAC water pipe 1 itself. Long-term use will not affect the strength and sealing of the HVAC water pipe 1, ensuring the safe and stable operation of the HVAC water pipe 1.

[0032] like Figure 3 and Figure 5 As shown, the scale monitoring component 3 includes a fixing ring 301 disposed on the outside of the HVAC water pipe 1. A second mounting plate 302 is fixedly connected to the top of the fixing ring 301, and a scale thickness monitor 303 is bolted to the top of the second mounting plate 302. A groove is formed on the inner wall of the fixing ring 301, located below the HVAC water pipe 1. A spring 304 is bolted to the inner bottom wall of the groove, and a probe 305 is fixedly installed at the other end of the spring 304. The probe 305 fits against the outer wall of the HVAC water pipe 1. In use, the spring 304 in the groove of the inner wall of the fixing ring 301 will give the probe 305 an upward elastic force, so that the probe 305 fits tightly against the outer wall of the HVAC water pipe 1. The probe 305 can convert the scale thickness information in the HVAC water pipe 1 into an electrical signal and transmit it to the scale thickness monitor 303. The scale thickness monitor 303 directly displays the scale thickness value on a digital display screen, and the operator can understand the scale thickness in the HVAC water pipe 1 through the scale thickness monitor 303.

[0033] like Figure 3As shown, the scale removal assembly 4 includes an electronic descaling device 401 fixedly installed on top of two adjacent sets of clamps 201. The electronic descaling device 401 is located on one side of the scale thickness monitoring device 303. A coil 402 is wound around the outer wall of the HVAC pipe 1, and the coil 402 is located below the electronic descaling device 401. The electronic descaling device 401 and the coil 402 are fixedly connected by a wire. When the coil 402 receives the electrical signal transmitted from the electronic descaling device 401, an alternating electromagnetic field is generated around the coil 402 according to the principle of electromagnetic induction. When the HVAC water flows in the HVAC pipe 1, it passes through the alternating electromagnetic field generated by the coil 402. For the scale that has already adhered to the inner wall of the HVAC pipe 1, the alternating electromagnetic field will change its internal microstructure. Over time, the scale will gradually peel off and be discharged from the HVAC pipe 1 with the water flow, thereby achieving the purpose of removing scale. At the same time, the electromagnetic field will also change the structure of water molecules, enhance the activity of water molecules, improve the water's ability to dissolve calcium and magnesium ions, and further inhibit the formation of scale.

[0034] like Figure 3 As shown, a PLC controller 5 is bolted to the first mounting plate 202. The PLC controller 5 is located on one side of the electronic descaling device 401. The PLC controller 5 is powered by an external power source and is electrically connected to the ultrasonic transducer 204, the scale thickness monitor 303, and the electronic descaling device 401. In use, the scale thickness monitor 303 continuously monitors the scale thickness on the inner wall of the HVAC water pipe 1 in real time and transmits the electrical signal representing the scale thickness to the PLC controller 5. The PLC controller 5 compares the received scale thickness electrical signal with a preset scale thickness threshold. If it exceeds the safe range, the PLC controller 5 sends a descaling command to the electronic descaling device 401 and simultaneously starts the ultrasonic generator 203 to assist in the descaling operation. The PLC controller 5 can automatically control the electronic descaling device 401 and other equipment according to the preset program and real-time collected data, without the need for constant manual monitoring and operation.

[0035] like Figure 3 and Figure 6 As shown, a retaining ring 6 is sleeved on the outer side of the ultrasonic transducer 204. The retaining ring 6 is sleeved on the HVAC water pipe 1, and the inner wall of the retaining ring 6 is in contact with the outer wall of the gasket 205. The retaining ring 6 effectively prevents the ultrasonic transducer 204 from loosening or shifting due to factors such as vibration, water flow impact, or temperature changes during the operation of the HVAC system. This ensures that the ultrasonic transducer 204 is always in the correct working position. The buffering effect of the gasket 205 can reduce the friction and vibration between the retaining ring 6 and the ultrasonic transducer 204, reducing the risk of damage to the ultrasonic transducer 204 due to mechanical stress.

[0036] like Figure 6As shown, the inner side of the retaining ring 6 is filled with memory foam, which conforms to the outer wall of the HVAC pipe 1. Memory foam has unique slow rebound properties; when subjected to pressure, it gradually deforms and tightly conforms to the surface contour of the HVAC pipe 1, enhancing the fixing effect between the retaining ring 6 and the HVAC pipe 1. This prevents the transducer from shifting due to vibration of the HVAC pipe 1 or external forces, and also provides a certain degree of sealing, reducing interference from the external environment on the propagation of ultrasonic signals.

[0037] like Figure 2 As shown, the retaining ring 301 is fixedly sleeved onto the HVAC water pipe 1 by bolts and is located on one side of the clamp 201. When maintenance, repair or replacement of parts is required for the HVAC water pipe 1 system, the bolt-fixed retaining ring 301 can be easily removed for convenient use.

[0038] Specifically, when using the scale monitoring and removal system on the inner wall of this HVAC water pipe 1: ... Figure 3 and Figure 5 As shown, the spring 304 in the groove of the inner wall of the fixing ring 301 provides an upward elastic force to the probe 305, causing the probe 305 to fit tightly against the outer wall of the HVAC water pipe 1. The probe 305 can convert the thickness information of the scale inside the HVAC water pipe 1 into an electrical signal and transmit it to the scale thickness monitor 303. The scale thickness monitor 303 transmits the electrical signal representing the scale thickness to the PLC controller 5. The PLC controller 5 compares the received scale thickness electrical signal with a preset scale thickness threshold. If it exceeds the safe range, The PLC controller 5 sends a descaling command to the electronic descaling device 401. When the coil 402 receives the electrical signal transmitted from the electronic descaling device 401, an alternating electromagnetic field is generated around the coil 402 according to the principle of electromagnetic induction. When the heating water flows in the heating water pipe 1, it passes through the alternating electromagnetic field generated by the coil 402, and the scale gradually peels off and is discharged from the heating water pipe 1 with the water flow, thereby achieving the purpose of removing scale. In addition, the PLC controller 5 simultaneously starts the ultrasonic generator 203 to assist in the descaling operation. Figure 2 , Figure 3 and Figure 6 As shown, after receiving the high-frequency electrical signal from the ultrasonic generator 203, the ultrasonic transducer 204 will generate high-frequency mechanical vibration. The high-frequency mechanical vibration will propagate rapidly along the wall of the heating and ventilation water pipe 1 and be transmitted to the water in the heating and ventilation water pipe 1 and the scale adhering to the inner wall of the heating and ventilation water pipe 1. Under the action of the high-frequency vibration of the ultrasonic waves, the scale will gradually peel off from the inner wall of the heating and ventilation water pipe 1, thereby achieving the purpose of removing scale.

[0039] All technical features in this embodiment can be freely combined according to actual needs.

[0040] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
