Description

Technical Field

[0001] This invention relates to the technical field of building drainage and water drainage, and in particular to a cleaning device, cleaning system and cleaning method for basement drainage structures. Background Technology

[0002] In the safety design of urban underground space-related projects, the application of active anti-buoyancy technology is becoming more and more widespread. The main principle is to collect groundwater into a sump well for centralized treatment in order to avoid the underground structure being damaged by buoyancy due to excessively high groundwater levels.

[0003] Groundwater often contains sediment such as silt. If not cleaned promptly, this sediment can clog channels, preventing groundwater from entering the collection well and causing the well to malfunction. Current technology typically involves manual flushing, but this method is limited to a single flushing approach: flushing from the collection well towards the groundwater channel, followed by water dilution and waiting for the diluted sediment to flow out naturally. This only temporarily alleviates the blockage, as the sediment cannot be quickly removed and will soon cause another blockage.

[0004] Therefore, how to quickly remove sediment from underground water channels has become a design challenge for urban underground space-related engineering projects. Summary of the Invention

[0005] The technical problem to be solved by this invention is: how to quickly remove sediment from underground water channels.

[0006] To address the aforementioned technical problems, this invention provides a cleaning device, cleaning system, and cleaning method for a basement drainage structure. A first aspect of this invention provides a cleaning device for a basement drainage structure. The cleaning device is installed in a sump and a sedimentation tank. A water pump is installed in the sump, and a water-air pulse generator is installed outside the sump. The cleaning device includes: a first pipe, one end of which extends into the sedimentation tank, and the other end is suspended above the sump, with a first electrically controlled valve at the other end; and a second pipe, one end of which is connected to the water pump, and the other end is connected to the middle of the first pipe, with a second electrically controlled valve installed in the middle of the second pipe. The system includes a control valve and a third pipeline, one end of which is inserted into the grit chamber, and the other end which is detachably connected to a water-air pulse generator. When the water-air pulse generator is removed, the first electrically controlled valve is closed, and the second electrically controlled valve is opened. The water pump supplies water to the second pipeline, and the water flows sequentially into the second pipeline, the first pipeline, and the grit chamber. The sediment in the grit chamber is discharged through the third pipeline along with the water flow. When the water-air pulse generator is installed, the second electrically controlled valve is closed, and the first electrically controlled valve is opened. The water-air pulse generator introduces pulse fluid into the third pipeline, and the sediment in the grit chamber enters the first pipeline along with the pulse fluid and is discharged through the first electrically controlled valve.

[0007] In one embodiment, the water collection well is equipped with a well cover, and both the first electrically controlled valve and the second electrically controlled valve are located above the well cover.

[0008] In one embodiment, the third pipe is used to connect one end of the water-gas pulse generator located above the manhole cover.

[0009] In one embodiment, any one of the electrically controlled valves is any one of the following: an electromagnetically driven valve, a motor-driven valve, or an electro-hydraulic / pneumatic linkage valve.

[0010] A second aspect of the present invention provides a cleaning system for a basement drainage structure, comprising: two collection wells; two sedimentation tanks; a blind drain connecting the two sedimentation tanks; two cleaning devices provided in the first aspect of the present invention, the two cleaning devices being installed correspondingly in the two collection wells; a third electrically controlled valve being provided at one end of the third pipe of each cleaning device connected to a water-air pulse generator; in the first cleaning device, the second and third electrically controlled valves are closed, and the first electrically controlled valve is opened; in the second cleaning device, the first and third electrically controlled valves are closed, and the second electrically controlled valve is opened, so that the water supplied by the pump in the second cleaning device passes sequentially through the second pipe, the first pipe, the sedimentation tank, and the blind drain before entering the sedimentation tank of the first cleaning device, and then through the first pipe and the first electrically controlled valve of the first cleaning device into the collection well of the first cleaning device; when changing the flushing direction, in the first cleaning device, the first and third electrically controlled valves are closed, and the second electrically controlled valve is opened; in the second cleaning device, the second and third electrically controlled valves are closed, and the first electrically controlled valve is opened, so that the sediment in the sedimentation tank enters the collection well of the second cleaning device.

Open the second electrically controlled valve, allowing the water pump supplied by the water pump in the second part of the water collection well cleaning device to flow sequentially through the second pipe, the first pipe, the sedimentation tank, and the drainage layer before entering the sedimentation tank of the first part of the water collection well cleaning device. The water then flows through the first pipe and the first electrically controlled valve of the first part of the water collection well cleaning device into the first part of the water collection well, thus cleaning the drainage layer. When changing the flushing direction, in the first part of the water collection well cleaning device, close the first and third electrically controlled valves and open the second electrically controlled valve. In the second part of the water collection well cleaning device, close the second and third electrically controlled valves and open the first electrically controlled valve, allowing the sediment in the drainage layer to enter the second part of the water collection well.

[0012] A fourth aspect of the present invention provides a cleaning method for a basement drainage structure, applied to a controller electrically connected to a cleaning device, the cleaning device being the cleaning device as described in any one of the claims; the cleaning method includes: S11, closing a first electrically controlled valve and opening a second electrically controlled valve; S12, starting a water pump to supply water to a second pipe, causing water to flow sequentially into the second pipe, the first pipe, and a sedimentation tank, with sediment in the sedimentation tank being discharged through a third pipe along with the water flow; S13, closing the second electrically controlled valve and opening the first electrically controlled valve; S14, starting a water-air pulse generator to introduce pulse fluid into the third pipe, causing sediment in the sedimentation tank to enter the first pipe along with the pulse fluid and be discharged through the first electrically controlled valve.

[0013] In one embodiment, the cleaning system includes two collection wells, two sedimentation tanks, a blind drain, and two cleaning devices. The blind drain connects the two sedimentation tanks, and the two cleaning devices are installed correspondingly in the two collection wells. A third electrically controlled valve is provided at one end of the third pipe of each cleaning device connected to a water-air pulse generator. The cleaning method further includes: S21, closing the second and third electrically controlled valves in the first cleaning device and opening the first electrically controlled valve in the first cleaning device; S22, closing the first and third electrically controlled valves in the second cleaning device and opening the second electrically controlled valve in the second cleaning device; S23, turning on the water pump in the second cleaning device, so that water flows sequentially through the second pipe, the first pipe, the sedimentation tank, and the blind drain before entering... S24. The water enters the sedimentation tank of the first cleaning device and flows through the first pipe and the first electrically controlled valve of the first cleaning device into the collection well of the first cleaning device; S25. The water enters the sedimentation tank of the first cleaning device and flows through the first pipe and the first electrically controlled valve of the first cleaning device into the collection well of the first cleaning device; S26. The water pump in the first cleaning device is turned on, so that the water flows through the second pipe, the first pipe, the sedimentation tank and the blind ditch in sequence into the sedimentation tank of the second cleaning device, and flows through the first pipe and the first electrically controlled valve of the second cleaning device into the collection well of the second cleaning device.

[0014] In one embodiment, the cleaning system includes several collection wells, several sedimentation tanks, several cleaning devices, and a drainage layer. The sedimentation tanks are located near the collection wells, and the cleaning devices are installed in the collection wells. The drainage layer connects to the sedimentation tanks. The cleaning method further includes: S31, closing the second and third electrically controlled valves in the cleaning device of the first collection well, and opening the first electrically controlled valve in the cleaning device of the first collection well; S32, closing the first and third electrically controlled valves in the cleaning device of the second collection well, and opening the second electrically controlled valve in the cleaning device of the second collection well; S33, turning on the water pump in the cleaning device of the second collection well, so that water flows sequentially through the second pipe, the first pipe, the sedimentation tank, and the drainage layer before entering the cleaning device of the first collection well. S34.

[0016] Compared with the prior art, the cleaning device, cleaning system, and cleaning method for basement drainage structures according to embodiments of the present invention have the following advantages: The cleaning device of this invention employs a combination of multiple pipes and electrically controlled valves, forming a flushing direction from the collection well to the sedimentation tank (i.e., the groundwater passage) and a flushing direction from the sedimentation tank to the collection well. Water pumps and water-air pulse devices provide power to the fluids in both flushing directions, enabling not only the delivery of water from the collection well to the sedimentation tank for dilution and removal of sediment, but also the delivery of fluid from the outside to the sedimentation tank to remove sediment. Compared to traditional cleaning methods that involve diluting with water and waiting for it to flow out naturally, this invention features corresponding pipes and valves in each flushing direction, allowing fluid pressure to dilute and remove sediment in either direction, resulting in a faster and more thorough process than natural flow and effectively alleviating blockages. Furthermore, because of the two-way cleaning, sediment is less likely to get stuck at the joints, leading to a more thorough cleaning. Attached Figure Description

[0027] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0028] In the description of this invention, it should be understood that the terms "first," "second," etc., in the specification, claims, and accompanying drawings are intended to distinguish similar objects and are not intended to describe a specific structure. It should be understood that such terms are interchangeable where appropriate so that embodiments of the invention can be implemented in structures other than those illustrated or described. Furthermore, "comprising," "having," and any variations thereof are intended to cover non-exclusive inclusions. For example, a product or device comprising a series of components or units is not necessarily limited to those explicitly listed, but may also include other components or units not explicitly listed but inherent to these products or devices. "Electrically controlled valve" refers to a valve that controls the flow of water or regulates its flow rate via electrical signals (such as current, voltage, wireless commands, etc.).

[0029] With the increasing development of urban underground space, the safety and stability of projects such as underground parking lots and underground commercial complexes are receiving more and more attention. Among them, "structural damage caused by groundwater buoyancy" is one of the core safety hazards faced by such projects. To address this hazard, active anti-buoyancy technology is being used more and more widely in engineering design. Its core working principle is: relying on a pre-designed underground water channel, the dispersed groundwater in the underground space is concentrated and diverted to a collection well. The drainage system of the collection well achieves the orderly discharge of groundwater, thereby lowering the groundwater level, offsetting the buoyancy force on the underground structure, and ensuring the structural safety of the project.

[0030] However, in the actual operation of active anti-buoyancy technology, groundwater often carries sediments such as silt and gravel particles. These sediments gradually accumulate on the inner walls of the groundwater channels as the groundwater flows, and long-term accumulation can lead to narrowing or even complete blockage of the channels. Once the channels are blocked, groundwater cannot flow normally into the sump, directly cutting off the "inlet-outlet" link of the active anti-buoyancy system. This causes the sump to lose its anti-buoyancy drainage function, which in turn leads to safety risks such as groundwater level rise and structural cracking due to buoyancy, seriously affecting the normal use of underground engineering projects.

[0031] To address the problem of sediment blockage in underground water channels, existing technologies mostly employ manual flushing, and the flushing pattern is singular and fixed: operators manually set up pipes and turn on water pumps to flush the underground water channels in a one-way direction from the collection well. After the sediment in the channel is diluted by the water flow, the diluted mud-water mixture is allowed to flow out of the channel naturally.

[0032] However, this solution has significant limitations. On the one hand, manual operation is inefficient and the working environment is risky, making it difficult to meet the maintenance needs of large-scale underground projects. On the other hand, single forward flushing can only act on loose sediment on the surface of the channel, failing to effectively remove impurities attached to the inner wall of the channel. Furthermore, it lacks the power to actively remove slag, and the diluted sediment is prone to re-accumulating downstream, leading to repeated blockages. It can only provide a temporary relief from blockages and cannot achieve long-term effectiveness.

[0033] Based on this, such as Figure 1 As shown in the preferred embodiment of the present invention, a cleaning device 10 for a basement drainage structure is provided. The cleaning device 10 is installed in a water collection well 11 and a sedimentation tank 12. A water pump 13 is installed in the water collection well 11, and a water-air pulse generator 14 is installed outside the water collection well 11. The cleaning device 10 may include a first pipe 101, a second pipe 102, and a third pipe 103.

[0034] One end of the first pipe 101 is inserted into the sedimentation tank 12, and the other end is suspended on the water collection well 11. The other end is equipped with a first electrically controlled valve 1011. One end of the second pipe 102 is connected to the water pump 13, and the other end is connected to the middle of the first pipe 101. A second electrically controlled valve 1021 is installed in the middle of the second pipe 102. One end of the third pipe 103 is inserted into the sedimentation tank 12, and the other end is detachably connected to the water-air pulse generator 14.

[0035] The pipes using the cleaning device 10 described above, such as Figure 2 As shown by the arrow, when the water-air pulse generator 14 is removed, the first electrically controlled valve 1011 is closed and the second electrically controlled valve 1021 is opened. The water pump 13 can then supply water to the second pipe 102. The water flows sequentially into the second pipe 102, the first pipe 101, and the sedimentation tank 12. At this time, the pressure in the sedimentation tank 12 increases. Since the third pipe 103 is reserved for opening, the sediment in the sedimentation tank can be discharged through the third pipe 103 with the water flow.

[0036] When the water-air pulse generator 14 is installed, such as Figure 3As indicated by the arrow, the second electrically controlled valve 1021 is closed and the first electrically controlled valve 1011 is opened. The water-air pulse generator 14 can be used to introduce pulse fluid into the third pipe 103. At this time, the pressure in the sedimentation tank rises. Since the second electrically controlled valve 1021 is closed but the first electrically controlled valve 1011 is open, the original second pipe 102 becomes an open pipe facing the collection well 11. At this time, the sediment in the grit chamber 12 enters the first pipe 101 with the pulse fluid and is discharged into the collection well 11 through the opened first electrically controlled valve 1011.

[0037] Through the above scheme, flushing in two directions can efficiently remove sediment from the underground water channel and quickly remove impurities from the channel, thus ensuring the continuous and stable operation of the active anti-buoyancy system.

[0038] Meanwhile, the flushed sediment can be directly flushed to the area around or into the collection well 11, so it can be collected and removed in a concentrated manner, and will not be left in the sedimentation tank or other channels to cause secondary blockage.

[0039] Because the valves are electrically controlled, operators do not need to enter the water collection well 11. The system can be remotely controlled or automated by the controller, which reduces the difficulty of cleaning.

[0040] Furthermore, in one embodiment of the present invention, the water collection well 11 is equipped with a well cover 111, and the first electrically controlled valve 1011, the second electrically controlled valve 1021, and the third electrically controlled valve 1031 are all located above the well cover 111. Since each electrically controlled valve is located above the well cover 111, the waterproof requirements for the electrical signal wiring are lower, making it less prone to water ingress damage, and facilitating installation and maintenance.

[0041] Correspondingly, the end of the third pipe 103 in this invention used to connect to the water-gas pulse generator 14 can also be located above the well cover 111. Since the end of the third pipe 103 used to connect to the water-gas pulse generator 14 is also the sediment outlet when the water pump 13 is used as power for cleaning, the sediment can be directly carried out of the collection well 11, reducing the process of centralized retrieval.

[0042] The first electrically controlled valve 1011, the second electrically controlled valve 1021, and the third electrically controlled valve 1031 of this invention can be any of the following: an electromagnetically driven valve, a motor-driven valve, or an electro-hydraulic / pneumatic linkage valve.

[0043] Specifically, the electromagnetic drive valve can be: a direct-acting electromagnetic valve, a pilot-operated electromagnetic valve, a magnetically controlled electric water valve, or an electromagnetically driven quick-connect valve. Motor-driven valves can specifically include: electric ball valves, electric butterfly valves, electric gate valves, electronic multi-way valves, smart water meters with valves, and smart electrically controlled diaphragm valves with flow feedback. Electro-hydraulic / pneumatic linkage valves can specifically include: electromagnetic hydraulic slow-closing gate valves, pneumatic electric control valves, and hydraulic pilot valves with electric control.

[0044] Correspondingly, such as Figure 4 As shown, the present invention also provides a cleaning system 1 for a basement drainage structure, including two water collection wells 11, two sedimentation tanks 12, blind drains 15, and two cleaning devices 10 provided in any embodiment of the present invention.

[0045] Blind drain 15 is used to connect two sedimentation tanks 12. Two cleaning devices 10 are installed on two collection wells 11 respectively. A third electrically controlled valve 1031 is provided at one end of the third pipe 103 of any cleaning device 10 that is connected to the water-air pulse generator 14.

[0046] When cleaning system 1 is working, such as Figure 4 As shown, in the first cleaning device 10, the second electrically controlled valve 1021 and the third electrically controlled valve 1031 are closed, and the first electrically controlled valve 1011 is opened. In the second cleaning device 10, the first electrically controlled valve 1011 and the third electrically controlled valve 1031 are closed, and the second electrically controlled valve 1021 is opened. This allows the water supplied by the water pump 13 in the second cleaning device 10 to flow sequentially through the second pipe 102, the first pipe 101, the sedimentation tank 12, and the blind drain 15 before entering the sedimentation tank 12 of the first cleaning device 10. The water then flows through the first pipe 101 and the first electrically controlled valve 1011 of the first cleaning device 10 into the collection well 11 of the first cleaning device 10.

[0047] When cleaning in reverse, such as Figure 5 As shown, the electrical control valves of the two cleaning devices 10 are operated in reverse (that is, in the first cleaning device 10, the first electrical control valve 1011 and the third electrical control valve 1031 are closed and the second electrical control valve 1021 is opened; in the second cleaning device 10, the second electrical control valve 1021 and the third electrical control valve 1031 are closed and the first electrical control valve 1011 is opened, so that the sediment in the sedimentation tank 12 enters the collection well 11 of the second cleaning device 10).

[0048] The cleaning system 1 is based on the double water collection well 11, the double sedimentation tank 12 and the blind ditch 15. With the corresponding cleaning device 10, it can cover the entire drainage link from water collection well 11 to sedimentation tank 12 to blind ditch 15, avoid missing easy-to-accumulate parts such as the connection between blind ditch 15 and sedimentation tank 12, and ensure the smooth flow of the drainage system.

[0049] By switching the electrically controlled valves of the two cleaning devices 10, bidirectional water flow rinsing can be flexibly achieved, breaking through the limitations of single forward rinsing. This not only removes loose impurities on the surface but also impacts downstream accumulated sediments, preventing secondary siltation and fundamentally solving the problem of repeated blockages.

[0050] Closing the third electrically controlled valve 1031 directs the water flow, preventing the impact force from weakening due to diversion. It concentrates the power to peel off the hardened sediment and guides the impurities into the collection well 11. This method of sludge removal is more thorough than the passive method of "water dilution and natural outflow," and reduces residue.

[0051] At the same time, this discharge structure does not damage the original hydrophobic and anti-buoyancy structure. After cleaning, the groundwater diversion function can be quickly restored, avoiding the failure of the anti-buoyancy of the water collection well 11, reducing the risk of groundwater level rise and structural damage due to buoyancy, and supporting the safe and stable operation of underground engineering.

[0052] like Figure 6 As shown, the present invention also provides another cleaning system 1 for a basement drainage structure, comprising: a plurality of water collection wells 11, a plurality of sedimentation tanks 12, a plurality of cleaning devices 10 provided in any embodiment of the present invention, and a drainage layer 16.

[0053] Several sedimentation tanks 12 are located near several water collection wells 11, and several cleaning devices 10 are installed in several water collection wells 11. A third electrically controlled valve 1031 is provided at one end of the third pipe 103 of any cleaning device 10 that connects to the water-air pulse generator 14. The hydrophobic layer 16 is connected to several sedimentation tanks 12.

[0054] In the cleaning device 10 of the first water collection well 11, the second electrically controlled valve 1021 and the third electrically controlled valve 1031 are closed, and the first electrically controlled valve 1011 is opened. In the cleaning device 10 of the second water collection well 11, the first electrically controlled valve 1011 and the third electrically controlled valve 1031 are closed, and the second electrically controlled valve 1021 is opened. This allows the water supplied by the water pump 13 in the cleaning device 10 of the second water collection well 11 to pass through the second pipe 102, the first pipe 101, the sedimentation tank 12, and the drainage layer 16 in sequence before entering the sedimentation tank 12 of the cleaning device 10 of the first water collection well. The water then passes through the first pipe 101 and the first electrically controlled valve 1011 of the cleaning device 10 of the first water collection well and enters the first water collection well 11, thereby cleaning the drainage layer 16.

[0055] When the flushing direction is changed, the electric control valves of the two water collection well cleaning devices 10 are operated in reverse (that is, in the first water collection well cleaning device 10, the first electric control valve 1011 and the third electric control valve 1031 are closed and the second electric control valve 1021 is opened; in the second water collection well cleaning device 10, the second electric control valve 1021 and the third electric control valve 1031 are closed and the first electric control valve 1011 is opened), so that the sediment in the hydrophobic layer 16 enters the second water collection well 11.

[0056] exist Figure 6 , Figure 7 as well as Figure 8In the top view, nine water collection wells 11 and nine sedimentation tanks 12 are used as an example, but the solution of the present invention is not limited to using nine sedimentation tanks 12, and can be any number of water collection wells 11 and sedimentation tanks 12 greater than 2.

[0057] like Figure 6 As shown, taking the direction in the figure as an example, the cleaning devices 10 in the three upper water collection wells 11 and the three lower water collection wells 11 are under positive pressure (corresponding to "+" in the figure), while the cleaning devices 10 in the three middle water collection wells 11 are under negative pressure (corresponding to "-" in the figure). The power source (such as water pump 13) in the six cleaning devices 10 can drive the water flow and sediment through the blind ditch 15 or the hydrophobic layer 16 to the three negative pressure water collection wells 11, thereby achieving the cleaning and sludge removal of the hydrophobic layer 16.

[0058] In this invention, the number of water collection wells in the first part can be one or more, and the number of water collection wells in the second part can also be one or more, thus generating a variety of combinations.

[0059] Furthermore, any arrangement can be used, such as Figure 7 The system employs eight positive pressure and one negative pressure. This allows the eight surrounding water collection wells 11 to apply flushing force towards the central water collection well 11. Figure 8 This shows Figure 7 The reverse cleaning operation.

[0060] The present invention also provides a cleaning method for a basement drainage structure, applied to a controller electrically connected to a cleaning device 10, wherein the cleaning device 10 is the cleaning device 10 in any embodiment. Figure 9 As shown, the cleaning method may include: S11. Close the first electrically controlled valve 1011 and open the second electrically controlled valve 1021.

[0061] S12. Start the water pump 13 to supply water to the second pipe 102, so that the water flows into the second pipe 102, the first pipe 101 and the sedimentation tank 12 in sequence. The sediment in the sedimentation tank 12 is discharged through the third pipe 103 with the water flow.

[0062] S13. Close the second electrically controlled valve 1021 and open the first electrically controlled valve 1011.

[0063] S14. Start the water-air pulse generator 14 to introduce pulse fluid into the third pipe 103, so that the sediment in the grit chamber 12 enters the first pipe 101 with the pulse fluid and is discharged through the first electrically controlled valve 1011.

[0064] In one embodiment, the cleaning system 1 includes two collection wells 11, two sedimentation tanks 12, a blind drain 15, and two cleaning devices 10. The blind drain 15 connects the two sedimentation tanks 12. The two cleaning devices 10 are installed correspondingly in the two collection wells 11. A third electrically controlled valve 103 is provided at one end of the third pipe 103 of any cleaning device 10 that connects to the water-air pulse generator 14. The cleaning method further includes: S21. Close the second electrically controlled valve 1021 and the third electrically controlled valve 1031 in the first cleaning device 10, and open the first electrically controlled valve 1011 in the first cleaning device 10.

[0076] In one embodiment, the cleaning device 10 further includes an electric quick connector connected between the water-air pulse generator 14 and the third pipe 103.

[0079] Electric quick-connectors enable automated control to rapidly disconnect and close the water-air pulse generator from the third pipeline, eliminating the need for manual twisting and disassembly of pipe connections. Compared to the physical labor and time required for manual installation and removal, electric control can instantly complete the disconnection and closure process. This is especially beneficial when the cleaning process requires frequent switching between "removing the water-air pulse generator (water flow flushing mode) - installing the water-air pulse generator (pulse fluid cleaning mode)," significantly shortening the interval between mode switching and improving overall cleaning efficiency.

[0080] Electric quick couplings replace manual intervention with automated control, eliminating the need for operators to enter complex work environments and directly contact pipelines, thus fundamentally avoiding the aforementioned safety hazards and reducing personnel operational risks.

[0081] The control of the electric quick coupling can be integrated into the automation logic of the overall cleaning system. There is no need for manual judgment of the timing of disassembly and assembly and the operation steps. Steps S41 to S42 can be completed synchronously through system commands. It works in synergy with the on / off control of the electric valves in the cleaning device to achieve fully automated cleaning.

[0082] It is understood that in this invention, when cleaning across collection wells, the second electrically controlled valve 1021 can be opened and the third electrically controlled valve 1031 closed, using a water pump as the cleaning power source; alternatively, the second electrically controlled valve 1021 can be closed and the third electrically controlled valve 1031 opened, using a water-air pulse generator 14 as the power source. For reverse cleaning, simply switch the third electrically controlled valve 1031 corresponding to the pulse generator 14 that needs to be opened, and close the other third electrically controlled valve 1031.

[0083] The cleaning system 1 and cleaning method of the present invention include all the technical features of the cleaning device 10. Therefore, the embodiments and beneficial effects of the cleaning device 10 are applicable to the cleaning system 1 and cleaning method of the present invention.

[0084] The above description is only a preferred embodiment of the present invention.
