[0050] The present application proposes a cleaning system.

[0051] See also Figure 1 The cleaning system includes: a cold water tank LT (Cold water Tank), a hot water tank HT (Hot water Tank), a water pump WP, a cooling system 20 and a cleaning device 10;

[0052] The cold water outlet p1 of the cold water tank LT and the first hot water outlet p2 of the hot water tank HT are connected to the water pump inlet of the water pump WP through a pipe, and a first valve SV1 is provided on the pipe;

[0053] The water pump outlet of the water pump WP is connected to the cleaning water inlet p3 of the cleaning device 10 and the cooling water inlet of the cooling system 20 through pipes, and a second valve SV2 is provided on the pipes;

[0054] The cooling water outlet of the cooling system 20 is connected to the first hot water inlet p4 of the hot water tank HT through a pipeline.

[0055] The cold water tank LT in this application is used to store cold water, and the hot water tank HT is used to store hot water. Figure 1 As can be seen, this example establishes a pipeline connection relationship between the cold water tank LT, the hot water tank HT, the water pump WP, the cooling system 20, and the cleaning device 10, and sets valves on the corresponding pipelines. By controlling the on-off state of the valves, automatic cold water cleaning and automatic hot water cleaning of the photovoltaic module are achieved. When the cleaning requirement is to perform cold water cleaning on the exterior of the photovoltaic module, it is only necessary to control the first valve SV1 and the second valve SV2 to conduct the corresponding main flow ports, so that the pipelines between the cold water tank LT, the water pump WP, and the cleaning device 10 are in a conducting state. After the cold water in the cold water tank LT is drawn out, the cold water is pumped into the cleaning device 10 by the water pump WP. The cleaning device 10 sprays the exterior of the photovoltaic module with the cold water pumped in by the water pump WP, thereby completing the cold water cleaning of the exterior of the photovoltaic module without manual operation.

[0056] When the cleaning requirement is to use hot water to clean the outside of the photovoltaic module, because there is a need to cool the internal temperature of the photovoltaic module to improve the power generation efficiency and extend the service life of the photovoltaic module, cold water is usually guided through the following Figure 2 The cooling system 20 shown attached to the back of the photovoltaic module is a horizontal S-shaped pipe that can transfer heat from the photovoltaic module to the water flowing through the cooling system 20, thereby achieving a cooling effect on the photovoltaic module. Based on this operation, this embodiment proposes pumping cold water from the cold water tank LT into the cooling system 20 from point A of the cooling system 20 via a water pump WP. This simultaneously cools the photovoltaic module and heats the cold water. The hot water generated by the heated cold water is output from point B of the cooling system 20 and stored in the hot water tank HT. This operation avoids the increased labor costs associated with manual heating and the increased device costs caused by the addition of additional heating devices.

[0057] When there is enough hot water stored in the hot water tank HT and the water temperature reaches the cleaning requirement, it is only necessary to control the first valve component SV1 and the second valve component SV2 to conduct the corresponding main flow outlets, so that the pipelines between the hot water tank HT, the water pump WP and the cleaning device 10 are in a conducting state, and the hot water in the hot water tank HT can be extracted and pumped into the cleaning device 10 through the water pump WP. The cleaning device 10 sprays the outside of the photovoltaic module based on the hot water pumped in by the water pump WP, thereby completing the hot water cleaning of the outside of the photovoltaic module without manual operation.

[0058] The specific cleaning operation process is as follows:

[0059] See Figure 3 and Figure 4 As shown, the first valve SV1 is a three-way valve, the cold water outlet p1 is connected to the first main outlet of the first valve SV1 through a pipe, the first hot water outlet p2 is connected to the second main outlet of the first valve SV1 through a pipe, and the water pump inlet is connected to the third main outlet of the first valve SV1 through a pipe. Figure 3 It can be seen that when the first valve component SV1 is a three-way valve component, only one valve component is required to achieve the switching between cold water output and hot water output. When the photovoltaic component needs to be cleaned with cold water, the first main outlet and the third main outlet of the first valve component SV1 are controlled to be connected, so as to connect the pipeline between the cold water outlet p1 and the water pump WP, so that the cold water output from the cold water outlet p1 can be transmitted to the water pump WP; when the photovoltaic component needs to be cleaned with hot water, the second main outlet and the third main outlet of the first valve component SV1 are controlled to be connected, so as to connect the pipeline between the first hot water outlet p2 and the water pump WP, so that the hot water output from the first hot water outlet p2 can be transmitted to the water pump WP.

[0060] Depend on Figure 4 It can be seen that the first valve component includes a first sub-valve component TSV1 and a second sub-valve component TSV2. The first sub-valve component TSV1 and the second sub-valve component TSV2 are two-way valve components. The first sub-valve component TSV1 is arranged on the pipe connecting the cold water tank LT and the water pump WP, and the second sub-valve component TSV2 is arranged on the pipe connecting the hot water tank HT and the water pump WP.

[0061] The pipe between the cold water outlet p1 and the water pump WP is called the first branch PI1. When the first sub-valve TSV1 is controlled to open, the first branch PI1 is connected. Cold water at the end of the first branch PI1 connected to the cold water outlet p1 flows through the open first sub-valve TSV1 to the other end of the first branch PI1, and then flows into the water pump WP. Conversely, when the first sub-valve TSV1 is controlled to close, the first branch PI1 is blocked, and no cold water flows into the water pump WP.

[0062] The pipe between the first hot water outlet p2 and the water pump WP is called the second branch PI2. When the second sub-valve TSV2 is controlled to open, the second branch PI2 is connected. Hot water at the end of the second branch PI2 connected to the first hot water outlet p2 flows through the opened second sub-valve TSV2 to the other end of the second branch PI2, and then flows into the water pump WP. Conversely, when the second sub-valve TSV2 is controlled to close, the second branch PI2 is blocked, and no hot water flows into the water pump WP.

[0063] Furthermore, Figure 3 and Figure 4 The second valve member in is also different. Figure 3 As can be seen, the second valve SV2 is a three-way valve. The water pump outlet is connected to the first main inlet of the second valve SV2 via a pipe. The cleaning water inlet p3 is connected to the second main inlet of the second valve SV2 via a pipe. The cooling water inlet is connected to the third main inlet of the second valve SV2 via a pipe. When the photovoltaic module needs to be cleaned, the first and second main inlets of the second valve SV2 are controlled to be connected, thereby connecting the pipe between the water pump WP and the cleaning device 10, allowing the water pumped from the water pump WP to be transferred to the cleaning device 10. When the water in the pipe needs to be heated, the first and third main inlets of the second valve SV2 are controlled to be connected, thereby connecting the pipe between the water pump WP and the cooling system 20, allowing the water pumped from the water pump WP to be transferred to the cooling system 20 for heating.

[0064] Depend on Figure 4 It can be seen that the second valve component includes a third sub-valve component TSV3 and a fourth sub-valve component TSV4, and the third sub-valve component TSV3 and the fourth sub-valve component TSV4 are two-way valve components. The third sub-valve component TSV3 is arranged on the pipeline connecting the water pump WP and the cleaning device 10, and the fourth sub-valve component TSV4 is arranged on the pipeline connecting the water pump WP and the cooling system 20, wherein the first main flow outlet of the fourth sub-valve component TSV4 is connected to the pipeline connecting the water pump WP and the third sub-valve component TSV3 through a pipeline.

[0065] The pipelines between the water pump WP and the cleaning device 10 are referred to as the third branch PI3 and the fourth branch PI4. The water pump WP is located on the third branch PI3, while the third sub-valve TSV3 is located on the fourth branch PI4. When the third sub-valve TSV3 is controlled to open, the fourth branch PI4 is connected. The end of the fourth branch PI4 that connects to the third branch PI3 receives water pumped by the water pump WP and transmits the pumped water to the cleaning device 10. Conversely, when the third sub-valve TSV3 is controlled to close, the fourth branch PI4 is blocked, and no water is pumped into the cleaning device 10.

[0066] The pipeline in which the fourth sub-valve TSV4 is located is referred to as the fifth branch PI5. When the fourth sub-valve TSV4 is controlled to be open, the fifth branch PI5 is connected. The end of the fifth branch PI5 connected to the fourth branch PI4 receives water pumped into the fourth branch PI4 by the water pump WP, and the pumped water is transferred to the cooling system 20. Conversely, when the fourth sub-valve TSV4 is controlled to be closed, the fifth branch PI5 is blocked, and no water flows into the cooling system 20.

[0067] It should be noted that the third branch PI3 is also equipped with a flowmeter FL, a pressure gauge PG, and a check valve CV. The flowmeter FL and pressure gauge PG are used to monitor the water flow and pressure in the third branch PI3, and the check valve CV is used to prevent water pumped into the fourth branch PI4 from flowing back into the water pump WP. The third branch PI3 is also connected to a seventh valve SV7 and a corresponding branch. This branch is used to drain the water in the third and fourth branches PI3 and PI4. Before hot water cleaning, the seventh valve SV7 can be opened to drain the cold water in the third and fourth branches PI3 and PI4, preventing the cold water in the third and fourth branches PI3 and PI4 from affecting the hot water cleaning effect.

[0068] Furthermore, the cleaning device 10 includes a nozzle NOZ and a water guide WD;

[0069] The cleaning water inlet p3 is connected to the nozzle NOZ and the water guide WD respectively through pipelines, and a sixth valve component SV6 is provided on the pipeline.

[0070] The pipeline between the cleaning water inlet p3, the nozzle NOZ, and the water guide WD is called the ninth branch PI9. When the sixth valve SV6 is controlled to open, the ninth branch PI9 is connected. Cold or hot water at the end connected to the cleaning water inlet p3 flows through the open sixth valve SV6 to the other end of the ninth branch PI9. The cold or hot water is then transferred through the ninth branch PI9 to the nozzle NOZ, where it is sprayed onto the exterior of the PV module, achieving external flushing of the PV module. Conversely, when the sixth valve SV6 is controlled to close, the ninth branch PI9 is disconnected, stopping the cleaning operation of the PV module.

[0071] Among them, one end of the nozzle NOZ is connected to the other end of the ninth branch PI9, and one end of the water guide WD is connected to the connection point of the nozzle NOZ and the ninth branch PI9. The water guide WD is used to guide the water remaining on the photovoltaic module during spraying.

[0072] It should be noted that the fourth branch PI4 is connected to the eighth valve component SV8 and a corresponding branch, which is used to drain the water in the ninth branch PI9 and the fourth branch PI4.

[0073] because Figure 3 and Figure 4 Except for the difference between the first valve part and the second valve part, the other components are the same. Figure 4 Take the sub-valve in as an example, the output is as follows Figure 5 As shown in the pipeline conduction circuit diagram, when the photovoltaic module needs to be cleaned with cold water, the first sub-valve TSV1, the third sub-valve TSV3 and the sixth valve SV6 are controlled to open, and the cold water in the cold water tank LT flows out from the cold water outlet, flows into the water pump WP through the conductive first branch PI1, and the water pump WP pumps the cold water into the conductive fourth branch PI4 through the conductive third branch PI3, and then transmits the cold water to the nozzle NOZ through the conductive ninth branch PI9, completing the transmission of cold water and cold water cleaning of the photovoltaic module, realizing automatic cold water cleaning of the photovoltaic module, and avoiding the problems of low cleaning efficiency and additional manual cleaning costs caused by manual cleaning.

[0074] Furthermore, a third valve component SV3 is provided on the pipe connecting the cooling water outlet and the first hot water inlet p4.

[0075] The pipe connected between the cooling water outlet and the first hot water inlet p4 is referred to as the sixth branch PI6. When the third valve SV3 is controlled to open, the sixth branch PI6 is connected to the cooling system 20. The end of the sixth branch PI6 connected to the cooling system 20 receives hot water output from the cooling system 20 and transfers the hot water to the hot water tank HT for storage. Conversely, when the third valve SV3 is controlled to close, the sixth branch PI6 is disconnected, and no hot water is added to the hot water tank HT.

[0076] by Figure 4 Take the sub-valve in as an example, the output is as follows Figure 6 As shown in the pipeline circuit diagram, when the cold water needs to be heated, the first sub-valve TSV1, the fourth sub-valve TSV4, and the third valve SV3 are controlled to open, and the cold water in the cold water tank LT flows out of the cold water outlet, flows through the open first branch PI1 to the water pump WP, and the water pump WP pumps the cold water through the third branch PI3 and the fourth branch PI4 to the open fifth branch PI5. The cold water is then transferred to the cooling system 20 for heating. The hot water output after the heating operation flows through the open sixth branch PI6 to the hot water tank HT for storage. This embodiment achieves simultaneous cooling of the photovoltaic module and heating of the cold water by transferring the cold water to the cooling system 20 attached to the back of the photovoltaic module, avoiding the need for manual heating and the additional heating costs incurred by the installation of additional heating devices.

[0077] Still Figure 4 Take the sub-valve in as an example, the output is as follows Figure 7As shown in the pipeline conduction circuit diagram, in order to enable the hot water heated by the cooling system 20 to reach the specified temperature required for hot water cleaning, the hot water in the hot water tank HT will be circulated and heated, and the second sub-valve TSV2, the fourth sub-valve TSV4 and the third valve SV3 are controlled to be open, and the hot water in the hot water tank HT is extracted through the conductive second branch PI2, and the hot water is pumped into the cooling system 20 through the conductive fifth branch PI5 by the water pump WP to circulate and heat the hot water.

[0078] Still Figure 4 Take the sub-valve in as an example, the output is as follows Figure 8 As shown in the pipeline conduction circuit diagram, after detecting that the hot water circulation is heated to the specified temperature, when the photovoltaic module needs to be cleaned with hot water, the fourth sub-valve TSV4 and the third valve SV3 are closed, and the third sub-valve TSV3 and the sixth valve SV6 are opened at the same time. The hot water in the hot water tank HT flows out from the first hot water outlet, flows into the water pump WP through the conductive second branch PI2, and the water pump WP pumps the hot water into the conductive fourth branch PI4 through the conductive third branch PI3, and then transmits the hot water to the nozzle NOZ through the conductive ninth branch PI9, completing the transmission of hot water and the hot water cleaning of the photovoltaic module, realizing automatic hot water cleaning of the photovoltaic module, and avoiding the problem of low cleaning efficiency that requires manual cleaning.

[0079] Furthermore, the hot water tank HT further comprises a second hot water outlet p5;

[0080] The second hot water outlet p5 is connected to the hot water supply port p6 via a pipe, which is equipped with a fourth valve SV4. The pipe in which the fourth valve SV4 is located is referred to as the seventh branch PI7. When the fourth valve SV4 is controlled to open, the seventh branch PI7 is connected. Hot water at the end connected to the second hot water outlet p5 flows through the open fourth valve SV4 to the other end of the seventh branch PI7, and then flows out of the hot water supply port p6, thus providing hot water supply. Conversely, when the fourth valve SV4 is controlled to close, the seventh branch PI7 is disconnected, stopping the hot water supply.

[0081] It should be noted that a flow meter FL and a pressure gauge PG are further provided on the seventh branch line PI7, wherein the flow meter FL and the pressure gauge PG are used to monitor the water flow and water pressure on the seventh branch line PI7.

[0082] by Figure 4 For example, the output is Figure 9As shown in the pipeline conduction circuit diagram, when hot water supply is needed, the fourth valve component SV4 is opened, and the hot water in the hot water tank HT flows out from the second hot water outlet and flows out from the hot water supply port p6 through the conductive seventh branch PI7. At the same time, the first sub-valve component TSV1, the fourth sub-valve component TSV4 and the third valve component SV3 can also be opened to replenish the hot water in the hot water tank HT, thereby achieving a continuous supply of hot water.

[0083] Furthermore, the cold water tank LT further comprises a cold water inlet p8;

[0084] The cold water inlet p8 is connected to the water supply port p7 via a pipe, which is equipped with a fifth valve SV5. The pipe containing the fifth valve SV5 is referred to as the eighth branch PI8. When the fifth valve SV5 is controlled to open, the eighth branch PI8 is connected. Cold water at the end connected to the water supply port p7 flows through the open fifth valve SV5 to the other end of the eighth branch PI8, and is then injected into the cold water tank LT through the eighth branch PI8. Conversely, when the fifth valve SV5 is controlled to close, the eighth branch PI8 is blocked, and the injection of cold water is stopped.

[0085] It should be noted that a check valve CV1 is connected between the water supply port p7 and the fifth valve member SV5 to prevent the cold water in the eighth branch PI8 from flowing back to the water supply port p7. The eighth branch PI8 is connected to a ninth valve member SV9 and a corresponding branch, which is used to drain the water in the eighth branch PI8. When the eighth branch PI8 needs to be cleaned, the ninth valve member SV9 can be opened to clean the eighth branch PI8 with cold water from the cold water inlet p8, thereby discharging the cold water used for cleaning the branch. This avoids the problem of using the cold water used for cleaning the branch to clean the photovoltaic panels, resulting in poor cleaning effect.

[0086] by Figure 3 or Figure 4 For example, the output is Figure 10 As shown in the pipeline conduction circuit diagram, when the cold water in the cold water tank LT needs to be supplemented, the fifth valve SV5 is opened and the cold water at the water supply port p7 is connected through the conductive eighth branch PI8.

[0087] For details, see Figure 11 As shown, Figure 11 The specific structures of the cold water tank LT and the hot water tank HT are shown. In this embodiment, a cold water outlet p1 is provided at the lower right side wall of the cold water tank LT, and a cold water inlet p8 is provided at the upper left side wall of the cold water tank LT.

[0088] An insulation layer I is provided on the outside of the hot water tank HT for keeping the hot water warm. A first hot water inlet p4 is provided on the upper wall of the hot water tank HT, a first hot water outlet p2 is provided on the lower right side wall of the hot water tank HT, and a second hot water outlet p5 is provided on the lower left side wall of the hot water tank HT.

[0089] The second branch PI2 connected to the first hot water outlet p2 and the seventh branch PI7 connected to the second hot water outlet p5 are each provided with a thermometer T. The thermometer T is used to monitor the water temperature at the first hot water outlet p2 and the water temperature at the second hot water outlet p5 in real time, thereby detecting whether the hot water temperature in the hot water tank HT reaches the specified temperature for hot water washing and the specified temperature for hot water supply.

[0090] Depend on Figure 11 It can be seen that Figure 11 The hot water tank HT and the cold water tank LT are integrated. In addition, the hot water tank HT and the cold water tank LT can also be Figures 1 to 10 The independent structures shown in .

[0091] In order to avoid the problem of bacteria growth caused by long-term storage of cold water in the cold water tank LT, the cold water in the cold water tank LT needs to be drained regularly. Therefore, a drain outlet p9 is provided at the lower part of the left side wall of the cold water tank LT in this embodiment. The drain outlet p9 is connected to the floor drain through a pipe. The pipe is the drainage branch PI10. The drainage branch PI10 is provided with a drainage valve SV10. When the cold water stored in the cold water tank LT needs to be drained, the drainage valve SV10 is opened, and the cold water in the cold water tank LT will be discharged through the drainage branch PI10.

[0092] like Figure 3 or Figure 4 As shown, the fourth valve component SV4 is a three-way valve component, the second hot water outlet p5 is connected to the first main outlet of the fourth valve component SV4 through a pipe, the hot water supply port p6 is connected to the second main outlet of the fourth valve component SV4 through a pipe, and the third main outlet of the fourth valve component SV4 is connected to the pipe connecting the fifth valve component SV5 and the cold water inlet p8 through a pipe.

[0093] When hot water supply is needed, the first main inlet and the second main inlet are controlled to be connected to achieve hot water supply. When the cold water tank LT and the corresponding pipes of the cold water tank LT need to be unblocked, or when the hot water in the hot water tank HT needs to be drained to prevent bacterial growth, the first main inlet and the third main inlet are controlled to be connected to inject the hot water in the hot water tank HT into the cold water tank LT. At this time, the corresponding valve can be opened to transfer the hot water in the cold water tank LT to the corresponding branch to unblock the pipes, avoiding pipe blockage caused by freezing in freezing environments such as winter, or the hot water in the cold water tank LT can be drained through the opened drain valve SV10.

[0094] In another embodiment, Figure 11 As shown, the cold water tank LT may further include a second hot water inlet p10, which is used to be connected to the third main flow port of the fourth valve member SV4 through a pipeline, and the first main flow port and the second main flow port of the fourth valve member SV4 are connected to Figure 3 and Figure 4 The connections are identical: the first main outlet is connected to the second hot water outlet p5 via a pipe, and the second main outlet is connected to the hot water supply port p6 via a pipe. When the cold water tank LT and its corresponding pipes need to be unblocked, or when the hot water in the hot water tank HT needs to be drained to prevent bacterial growth, the first and third main outlets of the fourth valve element SV4 are controlled to open, allowing the hot water in the hot water tank HT to be injected into the cold water tank LT via the second hot water inlet p10, unblocking the corresponding branch pipes or draining the hot water.
