Description

Technical Field

[0001] The invention relates to a window glass washing system, and in particular discloses a ship-based intelligent window washing system. Background Art

[0002] With the rapid development of electronic information technology, a large number of electronic information technology sensor products are used in ship design, and ships have gradually begun to change from traditional electromechanical control to intelligent control. The development of ship intelligence has improved the safety, economy and management efficiency of ship navigation. With the continuous progress and development of information technology, efficient, safe, stable, energy-saving and environmentally friendly intelligent equipment is an inevitable trend in the development of ship equipment.

[0003] In terms of glass cleaning in ship cabs, window washing systems have been widely used, which usually consist of three parts: a water supply unit, a control box, and a control console operation panel connected to the control box circuit. Figure 1 , which works as follows:

[0004] 1. Summer mode (temperature above 0 degrees)

[0005] Open solenoid valve V505, solenoid valve V502, solenoid valve V503 and solenoid valve V504 to start the first air purge to remove dust and impurities on the pipes and glass;

[0006] Open gate valve 108, check valve V109, solenoid valve V509, solenoid valve V502, solenoid valve V503 and solenoid valve V504, start water cleaning, and add cleaning agent as needed;

[0007] Open solenoid valve V505, solenoid valve V502, solenoid valve V503 and solenoid valve V504 to start the second air purge to dry the water on the pipes and glass to prevent ice from forming due to low temperature.

[0008] 2. Winter mode (temperature below 0 degrees)

[0009] Open solenoid valve V505, solenoid valve V502, solenoid valve V503 and solenoid valve V504 to start the first air purge to remove dust and impurities on the pipes and glass;

[0010] Open gate valve 108, gate valve V208, check valve V109, check valve V209, and adjust the mixing ratio of cold and hot water by turning manual mixing valve V501 to control the outlet temperature of the cleaning water;

[0011] Run the centrifugal pump, open the check valve V508, and the solenoid valve V507 to inject antifreeze into the main pipe, and mix it with the cleaning water in the main pipe, then open the solenoid valve V502, the solenoid valve V503 and the solenoid valve V504 to start water cleaning;

[0012] Open solenoid valve V505, solenoid valve V502, solenoid valve V503 and solenoid valve V504 to start the second air purge to dry the water on the pipes and glass to prevent ice from forming due to low temperature.

[0013] In the above control methods, it is not difficult to find that when the outdoor temperature is below 0 degrees, the system has the following problems:

[0014] 1. The first is temperature judgment. The operator needs to confirm the outdoor temperature before selecting the corresponding cleaning mode, and then determine whether antifreeze needs to be added. If the judgment is wrong, it is very likely that the water will freeze directly when spraying, which will not only fail to achieve the effect of glass cleaning, but also may cause the pipes to freeze and crack.

[0015] 2. Determination of outlet water temperature. The water supply unit is usually installed inside the hull, and there is a long pipe from the nozzle of the control console. In severe weather conditions, if the outlet water temperature is too low, it will cause ice to form directly when spraying water. In addition, there is no reference point for adjusting the outlet water temperature, and it is completely determined by manual adjustment, which brings certain difficulties to the operator. Moreover, the water temperature needs to be readjusted every time the equipment is cleaned, which is time-consuming and laborious.

[0016] 3. Antifreeze addition ratio. The freezing point of washing water after adding different ratios of antifreeze is different. Under normal circumstances, operators need to adjust the amount of antifreeze added according to the outdoor temperature. In actual operation, the temperature may change at any time due to changes in routes. In order to simplify the process, operators always mix according to the maximum limit temperature, which will greatly increase the cost of using the window washing system. Summary of the invention

[0050] The mixing barrel 1 is provided with an inlet pipeline main pipe, which is connected with the hot water inlet pipeline and the cold water inlet pipeline. A flow sensor (FM) 131 is provided on the inlet pipeline main pipe for detecting the water inlet flow. A first solenoid valve (EV1) 101 is provided on the hot water inlet pipeline, and a second solenoid valve (EV2) 102 is provided on the cold water inlet pipeline. The first solenoid valve (EV1) 101 and the second solenoid valve (EV2) 102 are respectively connected to the control box 3 circuit. The barrel body of the mixing barrel 1 is also provided with an electric heater 5 and a barrel temperature sensor (TT1) 71, a mixing barrel liquid level switch (LS1) 81 is provided on the top of the barrel body, an overflow port 141 is provided on the upper side wall of the barrel body, and a vent is also provided on the top of the barrel body. The mixing barrel liquid level switch (LS1) 81 is used to trigger the opening and closing of the first solenoid valve (EV1) 101 and the second solenoid valve (EV2) 102 through the liquid level switch signal it sends, starting at a low position and stopping at a high position, and outputting ultra-low liquid level and ultra-high liquid level alarm signals.

[0051] The bottom of the mixing barrel 1 is provided with two output branches, one of which is connected to the discharge port through the first ball valve (V1) 111, and the other is connected to several working areas through the second ball valve (V2) 112, the first pressure gauge (PI1) 91, the fresh water pump (P1) 61, the second pressure gauge (PI2) 92, and the first check valve (V3) 121 in sequence. At the same time, there is also a compressed air input pipeline, which is connected to the first check valve (V3) 121 through the third solenoid valve (EV3) 103. Each of the pipelines leading to the several working areas is provided with a solenoid valve. According to the attached Figure 2 When the present invention is set as a three-way working area pipeline, the pipeline leading to the first working area is provided with a fifth solenoid valve (EV5) 105, the pipeline leading to the second working area is provided with a sixth solenoid valve (EV6) 106, and the pipeline leading to the third working area is provided with a seventh solenoid valve (EV7) 107. The flow sensor (FM) 13, the electric heater 5, the barrel temperature sensor (TT1) 71, the mixing barrel liquid level switch (LS1) 81, the first ball valve (V1) 111, the second ball valve (V2) 112, the first pressure gauge (PI1) 91, the fresh water pump (P1) 61, the second pressure gauge (PI2) 92, the first check valve (V3) 121 and the solenoid valves provided on the pipelines leading to each working area are respectively connected to the control box 3 circuit, and the control box 3 controls the operation.

[0052] The antifreeze tank 2 is used to add antifreeze into the mixing barrel 1 in winter mode. The antifreeze outlet is arranged at the bottom of the antifreeze tank 2. A vent is arranged at the top of the antifreeze tank 2 to prevent the antifreeze pump (P2) 62 from forming a negative pressure when sucking and causing damage to the tank body. An antifreeze tank level switch (LS2) 82 connected to the control box 3 circuit is also provided to monitor the antifreeze status in the tank and output an alarm signal when the liquid level is extremely low.

[0053] The cab operation panel 4 is installed on the cab console. The operator can select the work area to be cleaned through the cab operation panel 4 and observe the cleaning effect. The control box 3 controls the system to execute the work. An outdoor temperature sensor (TT2) 72 connected to the cab operation panel 4 is also provided outside the cab for detecting the outdoor temperature.

[0054] The control box 3 can be a control box of model WWS-02-AE500 produced by Hansheng Company.

[0055] The working principle and working process of the present invention are as follows:

[0056] The control box 3 of the system of the present invention collects the temperature information of the outdoor temperature sensor (TT2) 72, selects the summer mode or the winter mode to operate, and determines the proportion of antifreeze to be added and whether to start the electric heater 5 to preheat the water temperature in the mixing barrel 1 by combining the collected temperature information of the barrel temperature sensor (TT1) 71 and the water intake of the mixing barrel 1 measured by the flow sensor (FM) 131, and confirms the water spraying temperature through the barrel temperature sensor (TT1) 71. The window washing process can be fully intelligently controlled. When the system of the present invention starts to operate in the winter mode, antifreeze can be added to the mixing barrel 1 first, and then the electric heater 5 can be operated to heat the water temperature in the mixing barrel 1 to the temperature required for water spraying.

[0057] According to the attached Figure 2 The operator selects the first working area, the second working area or the third working area for cleaning according to actual needs. The system of the present invention automatically determines whether to enter the winter mode according to the feedback of the outdoor temperature sensor (TT2) 72. The operator can also set an interval of adding antifreeze according to the actual situation of the ship route and the freezing point of the antifreeze, such as: adding 28% antifreeze at -10℃~0℃ and 38% at -20℃~-10℃. In this way, when antifreeze needs to be added, the system can automatically determine the proportion of antifreeze to be added.

[0058] When the system determines that it has entered the summer working mode, the specific cleaning steps are as follows:

[0059] 1. One air purge: The system automatically opens the third solenoid valve (EV3) 103, the fifth solenoid valve (EV5) 105, the sixth solenoid valve (EV6) 106 and the seventh solenoid valve (EV7) 107 to start the first air purge to remove dust and impurities on the pipes and glass;

[0060] 2. Water cleaning: open the second solenoid valve (EV2) 102, the fifth solenoid valve (EV5) 105, the sixth solenoid valve (EV6) 106, the seventh solenoid valve (EV7) 107, and the second ball valve (V2) 112, and run the fresh water pump (P1) 61 at the same time to perform water cleaning;

[0061] 3. Liquid replenishment: When the mixing tank liquid level switch (LS1) 81 detects that the liquid level in the mixing tank 1 is low, the second solenoid valve (EV2) 102 is opened to add cold water. When the set liquid level is reached, the second solenoid valve (EV2) 102 is closed;

[0062] 4. Secondary air purge: Open the third solenoid valve (EV3) 103, the fifth solenoid valve (EV5) 105, the sixth solenoid valve (EV6) 106 and the seventh solenoid valve (EV7) 107 to start the second air purge to dry the water on the pipes and the glass to avoid affecting the vision of the occupants or the driver, and to avoid water stains and dust accumulation.

[0063] When the system determines that it has entered the winter working mode, the specific cleaning steps are as follows:

[0064] 1. One air purge: The system automatically opens the third solenoid valve (EV3) 103, the fifth solenoid valve (EV5) 105, the sixth solenoid valve (EV6) 106 and the seventh solenoid valve (EV7) 107 to start the first air purge to remove dust and impurities on the pipes and glass;

[0065] 2. Adding antifreeze: The system makes a comprehensive judgment based on the outdoor temperature fed back by the outdoor temperature sensor (TT2) 72 and the liquid level in the mixing barrel 1 measured by the mixing barrel liquid level switch (LS1) 81 to open the fourth solenoid valve (EV4) 104 and operate the antifreeze pump (P2) 62 to add antifreeze;

[0066] 3. Preheating and water cleaning: The barrel temperature sensor (TT1) 71 feeds back the water temperature in the mixing barrel 1. When the water temperature is lower than the set water spraying temperature range, the electric heater 5 is operated for preheating until the water temperature reaches the set temperature, the fresh water pump (P1) 61 is operated, and the second solenoid valve (EV2) 102, the fifth solenoid valve (EV5) 105, the sixth solenoid valve (EV6) 106, the seventh solenoid valve (EV7) 107 and the second ball valve (V2) 112 are opened at the same time to start water cleaning;

[0067] 4. Liquid replenishment: When the mixing tank liquid level switch (LS1) 81 detects that the liquid level in the mixing tank 1 is low, the first solenoid valve (EV1) 101 is opened to add hot water. When the set liquid level is reached, the first solenoid valve (EV1) 101 is closed;

[0068] 5. Secondary air purge: After cleaning is completed, open the third solenoid valve (EV3) 103, the fifth solenoid valve (EV5) 105, the sixth solenoid valve (EV6) 106 and the seventh solenoid valve (EV7) 107 to start the second air purge to prevent freezing due to low temperature.

[0069] The present invention effectively solves the problems of inconvenient operation, inaccurate judgment and poor equipment maintainability in the prior art window washing system, simplifies the operation steps, improves the equipment operation efficiency, provides technical support for the intelligent development of ships, and has good technical advantages and application prospects.
