[0002] With the rapid development of the solar photovoltaic industry, the cleaning process in solar cell production places higher demands on the precision and efficiency of the solution preparation system. In related technologies, tank-type or chain-type cleaning equipment typically uses a solution buffer device in conjunction with a level gauge for solution preparation, which has the following technical drawbacks:

[0003] Insufficient liquid level accuracy: Traditional liquid level detection methods are affected by the large and irregular cross-sectional area of ​​the tank (such as the double track structure of chain equipment), resulting in falsely high liquid levels or detection errors, which affect the accuracy of liquid level distribution.

[0004] Therefore, how to solve the problem of insufficient solution preparation accuracy is a technical problem that urgently needs to be solved in this field.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore, the above description is not considered to constitute information related to the technology. Utility Model Content

[0046] Research has revealed that in related technologies, tank-type or chain-type cleaning equipment typically uses a chemical buffer device in conjunction with a level gauge for solution dispensing, which has the following technical defects:

[0047] 1. Insufficient liquid level accuracy: Traditional liquid level detection methods are affected by the large and irregular cross-sectional area of ​​the tank (such as the double track structure of chain equipment), resulting in falsely high liquid levels or detection errors, which affect the accuracy of liquid level detection.

[0048] 2. Low space utilization: The liquid buffer device occupies a large amount of space and is complex to maintain. Patent announcement number CN219025134U discloses a novel chain-type tank liquid dispensing system and chain-type cleaning equipment, which still relies on a secondary tank and bypass pipe structure and does not achieve direct pipeline monitoring.

[0049] 3. Insufficient dynamic control: Existing technologies control the liquid level through the linkage of a liquid level sensor and a replenishment valve, but lack real-time monitoring of flow rate and closed-loop regulation of the solenoid valve, resulting in slow liquid dispensing response speed.

[0050] Therefore, how to solve the above-mentioned defects is a technical problem that urgently needs to be solved in this field.

[0051] The defects in the above solutions and the reasons for their occurrence are the results of the inventors' practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventors' contributions to this disclosure.

[0052] 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.

[0053] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0054] like Figures 1 to 5 As shown, at least one embodiment provides a liquid preparation pipeline system for a cleaning equipment, including: a liquid supply tank 1, a pure water supply tank 2, a liquid tank 10, a circulation pipeline 14, and a drain pipeline 18. The liquid supply tank 1 is connected to the liquid tank 10 via a main pipeline 6 and a branch pipeline 9, forming a hierarchical control: both the main pipeline 6 and the branch pipeline 9 are equipped with solenoid valves 4 and manual valves 5; the main pipeline 6 is used for large-flow coarse liquid preparation, and the branch pipeline 9 is used for small-flow fine liquid preparation, both of which are equipped with clamp-type flow sensors 7. A control module is electrically connected to the clamp-type flow sensor 7 and the solenoid valve 4, and is configured to: when the flow data reaches the coarse preparation set threshold, control the solenoid valve 4 of the main pipeline 6 to close and open the solenoid valve 4 of the branch pipeline 9 to prepare the fine liquid; when the flow data reaches the fine preparation target value, control the solenoid valve 4 of the branch pipeline 9 to close, completing the liquid preparation; dynamically adjust the opening of the solenoid valve 4 so that the deviation between the actual flow and the set flow is ≤±0.5%. The clamp-type flow sensor 7 is electrically connected to the solenoid valve 4 on the pipeline, enabling real-time monitoring of flow data and closed-loop valve regulation. This design replaces the buffer device relied upon by the traditional level gauge 17, directly monitoring pipeline flow and reducing floor space.

[0055] Reference Appendix Figure 2 The clamp-type flow sensor 7 includes: a signal receiving and transmitting unit 702, a pipe clamp 706, and a flow module 707. The pipe clamp 706 is directly clamped to the outer wall of the liquid pipeline, and the flow module 707 is used to detect the flow rate of the liquid. The clamp-type flow sensor 7 also includes: a display screen 704 and a precision adjustment module 705. The display screen 704 displays the flow data in real time; the precision adjustment module 705 is used to adjust the monitored flow parameters.

[0056] Reference Appendix Figure 1 The medicine tank 10 is equipped with a liquid level float 13 to assist in monitoring the liquid level and trigger liquid replenishment, but the core accuracy is ensured by the flow module 707 to avoid false high-level errors caused by irregular tank shape. The circulation pipe 14 is connected to the circulation pump 15 to keep the medicine in the medicine tank 10 in an overflow state to ensure uniform concentration. An acid mist exhaust fan 3 is installed above the medicine tank 10 to extract volatile acid mist, which helps protect the environment. The drain pipe 18 and the quantitative discharge pipe 19 are set for medicine discharge, and together with the liquid level float 13, automatic discharge is achieved to avoid overflow.

[0057] like Figures 2 to 5As shown, at least one embodiment provides a clamp-type flow sensor, including: a sensor body 70, a signal receiving and transmitting unit 702, a pipe clamp 706, a flow module 707, a display screen 704, a switch 703, and a precision adjustment module 705. The switch 703 is used to start and stop the flow module 707; the pipe clamp 706 is detachably fixed to the outer wall of the liquid pipeline, measuring flow rate non-contactly to avoid contamination inside the pipeline. The signal receiving and transmitting unit 702 is electrically connected to a solenoid valve 4, controlling the valve's opening and closing based on the flow data. The display screen 704 displays the flow data in real time, and the precision adjustment module 705 allows the user to set flow parameters to adapt to different liquid mixing ratios. This sensor design addresses the problem of insufficient dynamic control in existing technologies, reducing the response time to milliseconds and avoiding liquid mixing overshoot. The detachable clamp facilitates maintenance and upkeep, and the non-contact measurement reduces the risk of corrosion, making it suitable for acid and alkaline liquid environments.

[0058] The working principle is as follows:

[0059] Start-up phase: Precision adjustment 705 sets the flow parameters, and display screen 704 monitors real-time data.

[0060] Coarse preparation process: The control module controls the solenoid valve 4 of the main pipeline 6 to open, and the liquid flows from the liquid supply tank 1 into the liquid tank 10 through the clamp-type flow sensor 7. The clamp-type flow sensor 7 monitors the flow rate in real time. When the coarse preparation set value is reached, the signal receiving and transmitting unit 702 sends a signal to the control module, and the control module controls the solenoid valve 4 of the main pipeline 6 to close, with the error controlled within ±2%.

[0061] Fine-mix solution preparation process: The control module controls the opening of solenoid valve 4 on branch pipe 9 to replenish the solution at a small flow rate. Clamp-type flow sensor 7 monitors the flow with high precision, and automatically closes solenoid valve 4 once the fine-mix set value is reached, completing the solution preparation. The entire response time is <100ms, avoiding liquid level fluctuations.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0063] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
