[0022] The present disclosure is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] The present invention proposes an intelligent water device for railway grinding vehicles with cleaning, dust suppression and fire fighting functions. It realizes high and low pressure switching through multiple sets of pressure regulating valves, which is used for both low pressure dust suppression and high pressure cleaning. Compared with the traditional method, it can meet the high and low pressure switching under different operation requirements, break through the functional limitations of the existing technology, and has strong adaptability to low temperatures, preventing the water pipe from freezing and cracking due to the expansion of water freezing.

[0025] Embodiment 1

[0026] Figure 1 The present invention provides an intelligent water device for cleaning, dust suppression and fire fighting functions for railway grinding vehicles. Figure 1 As shown:

[0027] An intelligent water device for cleaning, dust suppression and fire fighting for a railway grinding vehicle, comprising a water tank 1 and a water pump 2, the device also comprising a wind source system 13 for preventing pipes from freezing and cracking, the water tank 1 and the input end of the water pump 2 are connected, the output end of the water pump 2 is connected with a first pressure regulating valve 3 and a second pressure regulating valve 4, the first pressure regulating valve 3 and the second pressure regulating valve 4 are connected, and the first pressure regulating valve 3 is connected with a high-pressure flushing pipe 5 for flushing and cleaning the rail surface of the railway grinding, and the first pressure regulating valve 3 and the second pressure regulating valve 4 are connected with a low-pressure spray pipe 8 for dust reduction on the rail surface of the railway grinding;

[0028] When the water pump 2 delivers the water in the water tank 1 to the pipeline, the water pressure in the pipeline is detected by a preset pressure gauge, and the first pressure regulating valve 3 and the second regulating valve are adjusted according to the detected water pressure value. When the water pressure is adjusted to the preset value for flushing and cleaning by the first pressure regulating valve 3, the pipeline is connected to the high-pressure flushing pipe 5, so that the polished rail surface of the railway is flushed and cleaned; when the water pressure is adjusted to the preset value for dust suppression by the first pressure regulating valve 3 and the second regulating valve, the pipeline is connected to the low-pressure spray pipe 8, so that dust is reduced on the polished rail surface of the railway;

[0029] When the water pump 2 is not started, the wind in the wind source system 13 enters the pipeline, bringing out the water in the pipeline, and preventing the pipeline from freezing and cracking due to the expansion of water freezing.

[0030] In this solution, the first pressure regulating valve 3 and the second pressure regulating valve 4 are adjusted at the same time. When the water pressure is adjusted to the preset dust reduction value, the pipeline and the low-pressure spray pipe 8 are connected to reduce the dust on the polished rail surface of the railway. The first pressure regulating valve 3 and the second pressure regulating valve 4 are connected in series. Reducing the pressure of each group of pressure regulating valves will cause the water pressure in the pipeline to drop, so that the water source sprayed from the low-pressure spray pipe 8 is in a mist form, thereby reducing the dust on the polished rail surface of the railway.

[0031] In this embodiment, the water pump 2 is connected to a water system one-way valve through a pipeline to prevent the water source drawn from the water tank 1 by the water pump 2 from flowing back.

[0032] In the embodiment of the present invention, the one-way valve of the water system can effectively prevent the water in the pipeline from flowing back into the water pump 2 to cause damage or failure after the water pump 2 stops running. The design principle of the one-way valve is to set a controllable valve in the pipeline. When the water flow direction is opposite to the opening direction of the one-way valve, the valve will close, effectively preventing the water from flowing back.

[0033] The one-way valve can also protect the water pump 2 from water hammer impact in the pipeline, thereby extending the service life of the water pump 2. Water hammer phenomenon refers to the reverse shock wave generated when the water flow in the pipeline suddenly stops or changes direction, causing damage to the pipeline and the water pump 2. Through the control of the one-way valve, the occurrence of water hammer phenomenon can be effectively reduced, and the stability and safety of the use of the water pump 2 and the pipeline can be improved;

[0034] The installation and maintenance of the one-way valve are relatively simple, and it does not require regular inspection or maintenance. It is not prone to failure and has high reliability. By setting up a connection between the water pump 2 and the one-way valve of the water system, the safety and stability of the pipeline system can be improved, and a series of problems caused by water backflow and water hammer in the pipeline can be avoided. At the same time, the service life of the water pump 2 and the pipeline can be extended, and the reliability of the equipment can be improved; therefore, when installing or modifying the water pump 2, it should be considered to set up a one-way valve to enhance the stability and safety of the pipeline system.

[0035] In this solution, a single-stage pressure reducer is used to wash and clean the rail surface of the railway through the high-pressure washing pipe 5. The single-stage pressure reducer is a very simple pneumatic component. Compared with other pressure reducers, it does not require multi-stage adjustment and monitoring and has the characteristics of stability and reliability.

[0036] For high-pressure pipe cleaning operations, the use of a single-stage pressure reducer can provide stable and uniform water pressure to ensure cleaning results and operational safety;

[0037] In addition, high-pressure flushing will bring strong water flow force, which has a certain cleaning effect on impurities and dirt in the pipeline. The use of a single-stage pressure reducer can control the water pressure;

[0038] Ensure that the water flow mixes with the dirt inside the pipe to a certain extent to maximize the operation effect while reducing the generation of impurities;

[0039] The cost of a single-stage pressure reducer is relatively low, and it does not require complex monitoring and adjustment. Compared with other pressure reducers, it can reduce operating costs and improve cleaning effects. At the same time, by controlling the water pressure, water waste can be avoided and water resource consumption can be reduced;

[0040] When the rail surface of the railway is washed and cleaned through the high-pressure washing pipe 5, the use of a single-stage pressure reducer can provide stable and efficient water pressure, while also reducing costs and saving resources, which can be said to kill two birds with one stone.

[0041] In this solution, multi-stage pressure reduction is used to suppress dust on the rail surface of railway grinding through the low-pressure spray pipe 8. The multi-stage pressure reducer can regulate the flow rate and pressure within different pressure ranges, ensuring stable and reliable water flow output. For the operation of the low-pressure spray pipe 8, appropriate water pressure and flow can be provided to make the sprayed mist uniform and stable;

[0042] At the same time, the multi-stage pressure reducer has a high pressure control accuracy, avoiding excessively high or low water pressure, thereby reducing energy consumption and waste of water resources, saving operating costs;

[0043] The multi-stage pressure reducer can realize flow regulation within different pressure ranges. By increasing or decreasing the water pressure, the water droplet size can be reduced as much as possible under the premise of achieving dust suppression and dust reduction, thereby achieving mist-like water mist, which can reduce the waste of water resources while meeting the cleaning requirements;

[0044] Multi-stage pressure reducers have high precision, strong stability, and require low maintenance, which can extend service life and reduce maintenance costs;

[0045] Therefore, when dust is suppressed on the polished rail surface of the railway through the low-pressure spray pipe 8, the use of a multi-stage pressure reducer can provide more precise water pressure regulation and flow control, reduce the waste of water resources and cost consumption, while enhancing the purification effect, achieving a better dust suppression effect, and extending the service life of the multi-stage pressure reducer. It is an option with high economy and reliability.

[0046] In this embodiment, the high-pressure flushing pipe 5 is connected to a first pneumatic stop valve 6 for controlling the high-pressure flushing pipe 5 to be open or closed through a pipeline, the first pneumatic stop valve 6 is connected to a first solenoid valve 7 for controlling the first pneumatic stop valve 6 to be open or closed through a copper tube, the low-pressure spray pipe 8 is connected to a second pneumatic stop valve 9 for controlling the low-pressure spray pipe 8 to be open or closed through a pipeline, and the second pneumatic stop valve 9 is connected to a second solenoid valve 10 for controlling the second pneumatic stop valve 9 to be open or closed through a copper tube.

[0047] Solenoid valve is an automatic control element that works on the electromagnetic principle. It is widely used in industrial automation control systems. Its main function is to control the flow of gas or liquid and realize the functions of opening, closing, regulating and converting fluids.

[0048] Solenoid valves are usually composed of an iron core, a coil, a valve body, a spring, a guide plate, etc. When voltage is applied to the coil, an electromagnetic field is formed, which attracts the iron core and opens or closes the valve body. By controlling the opening and closing of the voltage, the working state of the solenoid valve can be controlled to make the gas or liquid flow or not, thereby realizing automatic control.

[0049] In this solution, the solenoid valve controls the opening or closing of the pneumatic stop valve. By reasonably controlling the opening and closing of the solenoid valve, the waste of water resources can be avoided and the use of water resources can be saved;

[0050] By controlling the opening and closing of the solenoid valve, the output flow and pressure of the water pump 2 can be accurately adjusted, thereby achieving precise control of the cleaning object and improving the cleaning accuracy;

[0051] Automatically control the cleaning process, which can achieve fast, efficient, safe and reliable cleaning process, and improve production efficiency and product quality;

[0052] In summary, the solenoid valve connected to the high-pressure flushing pipe 5 controls the pneumatic stop valve to open or close, which can achieve precise control of the cleaning process, improve cleaning efficiency and accuracy, reduce water waste, and improve production efficiency and product quality.

[0053] In this solution, the solenoid valve can also be replaced by an electric valve, which can accurately control the opening and closing degree of the valve disc, thereby achieving accurate control of parameters such as flow and pressure in the pipeline, and has high-precision control capabilities;

[0054] The electric valve can be remotely controlled, and the remote monitoring and control of the valve can be realized through the field controller, PLC and other control systems, avoiding the errors and inconveniences of manual operation;

[0055] The electric valve has a long service life and requires relatively few maintenance times. It has the characteristics of low cost, simple maintenance and convenient operation.

[0056] Selecting appropriate valve body materials according to different media can make the electric valve corrosion-resistant, non-toxic, and suitable for high-temperature and high-pressure corrosive media;

[0057] The electric valve has safety measures such as fast response, flexible operation, self-locking function, overload protection, etc., and can maintain stable working performance in harsh environments;

[0058] Electric valves can handle large flow media and are suitable for the control of liquid and gas media in various industrial pipelines.

[0059] In this embodiment, the air source system 13 is connected to the first pneumatic stop valve 6, the second pneumatic stop valve 9 and the third solenoid valve 14 through a pipeline, and the third solenoid valve 14 is connected to the purge air system check valve 15 through a pipeline.

[0060] In this solution, the solenoid valve and pneumatic stop valve are made of stainless steel, which has good corrosion resistance, especially in the environment of strong corrosive media such as acid and alkali, the valve made of stainless steel has good corrosion resistance;

[0061] Stainless steel valves can adapt to higher temperature and pressure ranges, so they can still maintain good performance and long life under some high temperature and high pressure conditions;

[0062] The surface of stainless steel valves is relatively smooth, easy to clean and disinfect, and will not cause toxic pollution to the medium. They are hygienic and non-toxic.

[0063] In summary, solenoid valves and pneumatic stop valves made of stainless steel are corrosion-resistant, suitable for high temperature and high pressure environments, and are sanitary and non-toxic. They can ensure the long-term and stable operation of the valves. When selecting valve materials, you need to choose according to the specific usage scenarios and medium characteristics.

[0064] When in use, the water pump 2 is connected to the one-way valve of the water system, and the one-way valve of the water system is opened to transport the water in the water tank 1 to the pipeline. The water pressure of the water in the pipeline is detected by a preset pressure gauge, and the first pressure regulating valve 3 and the second regulating valve are adjusted according to the detected water pressure value;

[0065] When the water pressure is adjusted to the preset value for flushing and cleaning through the first pressure regulating valve 3, the pipeline and the high-pressure flushing pipe 5 are connected, and at the same time, the first solenoid valve 7 connected to the high-pressure flushing pipe 5 through the pipeline is placed in an energized state, and the first pneumatic stop valve 6 connected to the high-pressure flushing pipe 5 is controlled to be in an open state, so that the water sprayed from the high-pressure flushing pipe 5 flushes and cleans the polished rail surface of the railway;

[0066] When the water pressure is adjusted to the preset dust reduction value through the first pressure regulating valve 3 and the second regulating valve, the pipeline and the low-pressure spray pipe 8 are connected, and at the same time, the second solenoid valve 10 connected to the low-pressure spray pipe 8 through the pipeline is placed in an energized state, and the second pneumatic stop valve 9 connected to the low-pressure spray pipe 8 is controlled to be in an open state, so that the water mist sprayed from the low-pressure spray pipe 8 reduces dust on the polished rail surface of the railway;

[0067] In this embodiment, the device also includes a wind source system 13 for preventing the pipeline from freezing and cracking. By starting the wind source system 13, the wind released by the wind source system 13 enters the pipeline, bringing out the water in the pipeline, preventing the pipeline from freezing and cracking due to the expansion of water freezing.

[0068] In the present invention, by opening the manual stop valve 12 connected to the pipeline, the wind in the wind source system 13 is brought into the pipeline, so as to prevent the pipeline from freezing and cracking due to the expansion of water freezing.

[0069] In cold seasons, water in the pipeline is easily affected by low temperature weather and freezes. As the volume expands, the pipeline will be damaged. By opening the manual stop valve 12 to bring wind into the pipeline, the temperature and pressure of the pipeline can be increased, the probability of freezing can be reduced, and the pipeline can be prevented from being damaged by freezing and cracking;

[0070] Ice in the pipeline will cause the inner diameter of the pipeline to become smaller, which will hinder the flow of the medium in the pipeline, thus forming a blockage in the pipeline. By opening the manual stop valve 12 to bring air into the pipeline, the speed and pressure of the medium flow can be increased to keep the pipeline unobstructed;

[0071] In winter, the weather is cold and the freezing of pipelines will slow down the flow of the medium in the pipelines, thus affecting production efficiency and quality.

[0072] By opening the manual stop valve 12 to bring air into the pipeline, not only can the pipeline be kept unobstructed, but the speed and pressure of the medium flow can also be increased, thereby improving production efficiency and quality.

[0073] When in use, in winter, low temperature can easily cause water pipes to freeze, expand, and crack. The wind source system 13 is installed on the side of the pipeline, connected to the pipeline, and the third solenoid valve 14 connected to the pipeline is placed in an energized state, controlling the purge air system check valve 15 to open, so that the wind from the wind source system 13 enters the pipeline to bring out the water in the pipeline, preventing the water pipes from freezing, expanding, and cracking; at the same time, the wind blown out by the wind source system 13 changes the first pneumatic stop valve 6 and the second stop valve to an open state, so that the wind blown out by the wind source system 13 brings out the water in the pipeline, preventing the water pipes from freezing, expanding, and cracking.

[0074] Embodiment 2:

[0075] Based on the first embodiment, Figure 1 As shown:

[0076] In this embodiment, the output end of the water pump 2 is connected to a fire hose reel 11 for extinguishing sparks or fire points generated during the railway grinding process.

[0077] In this embodiment, the fire hose reel 11 is connected to a manual stop valve 12 for controlling the fire hose reel 11 to be open or closed via a pipeline, and the manual stop valve 12 and the first pressure regulating valve 3 and the second pressure regulating valve 4 are connected via a pipeline.

[0078] In this solution, a manual stop valve 12 is used to control the state of the fire hose reel 11. The manual stop valve 12 is used to control the water spraying of the fire hose reel 11. The operation is simple and easy to use, does not require a complex control system and professional knowledge, and is easy to operate and easy to master.

[0079] The manual stop valve 12 has the characteristics of simple structure, reliable operation, low failure rate, etc., and can ensure the stable operation of the fire hose reel 11 water spray system;

[0080] The manual stop valve 12 has a fast reaction speed and quick response, and can quickly open or close the fire hose reel 11 water spray system to improve the spark point efficiency during grinding;

[0081] The manual stop valve 12 can open or close the water source at any time according to the needs of fire fighting and adjust the water output. It has the characteristics of strong flexibility and can meet the needs of spark points during grinding;

[0082] The use of the manual stop valve 12 does not require additional technical requirements, can be operated through training, does not require professional knowledge of fire-fighting equipment, and has low operating and maintenance costs.

[0083] When in use, the water pump 2 is connected to the one-way valve of the water system, and the one-way valve of the water system is opened to transport the water in the water tank 1 to the pipeline. The water pressure of the water in the pipeline is detected by a preset pressure gauge, and the first pressure regulating valve 3 and the second pressure regulating valve 4 are adjusted according to the detected water pressure value;

[0084] When the first pressure regulating valve 3 and the second pressure regulating valve 4 adjust the water pressure to the preset value for extinguishing sparks, the pipeline and the fire hose reel 11 are connected, and at the same time, the manual stop valve 12 connected to the fire hose reel 11 through the pipeline is turned to an open state, thereby extinguishing sparks or fire points generated during the railway grinding process through the water sprayed from the fire hose reel 11.

[0085] Embodiment three:

[0086] Based on the second embodiment, Figure 1-2 As shown:

[0087] In this embodiment, a heating device 16 is provided on the side of the water tank 1 to prevent the water inside the water tank 1 from freezing.

[0088] In this solution, the heating device 16 for preventing the water inside the water tank 1 from freezing can be an electric heater. An electric heater is installed inside the water tank 1 for heating to increase the water temperature in cold weather, thereby preventing the water from freezing;

[0089] At the same time, the heater can choose an intelligent electric heater with a temperature control device, which can automatically control the water temperature and effectively save energy;

[0090] At the same time, a special electric heating belt can be installed outside or inside the water tank 1 to increase the water temperature by electric heating, thereby preventing the water from freezing. The heating belts are of various forms, and different forms of heating belts can be selected according to actual needs; different forms of heating belts have different heating methods and effects, and selecting a suitable heating belt can improve the heating effect according to actual needs. For example, in some occasions where rapid heating is required, selecting a heating belt with a larger power can heat faster and more effectively; different forms of heating belts also differ in energy consumption, and selecting a suitable heating belt can reduce energy consumption according to actual needs. For example, in occasions where the heating time is not required, selecting a heating belt with a smaller power can save energy and reduce operating costs.

[0091] Some solar panels can also be installed around the water tank 1 to use solar energy for heating. Solar panels generally adopt a flexible structure and can be installed according to different shapes of water tanks 1. They are easy to use, environmentally friendly and energy-saving.

[0092] The installation of the heating device 16 can effectively prevent the water in the water tank 1 from freezing, and can ensure that the temperature in the water tank 1 is appropriate, thereby ensuring the water supply quality and service effect.

[0093] In this embodiment, a liquid level sensor 17 and an intelligent water replenishment system 18 are provided on the outer surface of the water tank 1. The water level in the water tank 1 is detected by the liquid level sensor 17. The liquid level sensor 17 determines whether the intelligent water replenishment system 18 is needed to replenish water in the water tank 1 according to the detected water level value.

[0094] In actual situations, acoustic wave detection can also be used instead of the liquid level sensor 17 to detect the water level in the water tank 1, and the water level change in the water tank 1 can be converted into acoustic waves. A special detection instrument can be used to detect the water level change in the water tank 1, which has high accuracy and fast response speed.

[0095] You can also use the good conductivity of water to insert electrodes into the water for conductivity detection, and determine the water level by detecting the current size;

[0096] The water level in the water tank 1 can also be converted into air pressure changes, and the water level can be determined by detecting the air pressure changes in the water tank 1 using a pressure probe;

[0097] The water level in the water tank 1 can be converted into a light signal by using physical principles such as laser and infrared, and the water level can be determined by detecting the reflection or penetration of light;

[0098] The water in the water tank 1 can also be leaked out through a pipe or a tube, and the water level in the water tank 1 can be determined by the rhythm of the dripping.

[0099] In the present invention, the intelligent water replenishment system 18 can realize water replenishment by using the pressure of the water tank 1 and the principle of gravity; by opening the connecting valve between the water tank 1 and the water replenishment area, water will flow freely to the water replenishment area. When the water level in the water replenishment area rises, the water pressure increases, and the detection valve in the water replenishment area will close. When the water level in the water tank 1 decreases, the water level in the water replenishment area drops, the detection valve automatically opens, and the water replenishment state is entered;

[0100] Fixed volume water replenishment can also be used. Fixed volume water replenishment means that a water tank 1 or pool with a certain capacity is installed in the water replenishment area. Once the water level drops below the set value, the water replenishment machine automatically starts to add water in the water replenishment area to the set value;

[0101] Pressure water replenishment can also be used. Pressure water replenishment means that tap water is directly pressed into the water tank 1 through the operation of a high-efficiency pressure pump.

[0102] In this solution, the intelligent water replenishment system 18 can automatically adjust the water level according to actual needs without manual intervention, thus reducing manual operations and improving the degree of automation;

[0103] The intelligent water replenishment system 18 can replenish water according to different plans, avoiding the influence of human factors on the amount and time of water replenishment, and the amount of water replenishment can be more stable;

[0104] The intelligent water replenishment system 18 can automatically adjust the water replenishment amount according to needs, avoiding waste, saving energy, and reducing the impact on the environment.

[0105] In this embodiment, the low-pressure spray pipe 8 is connected to a filter through a pipeline to filter large particles of impurities in the water in the pipeline.

[0106] The filter can filter out large particles of impurities in the pipeline to prevent these impurities from entering the low-pressure spray pipe 8 and causing blockage or damage to the low-pressure spray pipe 8. This can extend the service life of the low-pressure spray pipe 8;

[0107] The filter can keep the inside of the low-pressure spray pipe 8 clean, and prevent large particles of impurities accumulated inside the low-pressure spray pipe 8 from affecting the spray effect of the low-pressure spray pipe 8, thereby improving the performance of the low-pressure spray pipe 8;

[0108] The filter can filter out large particles of impurities in the pipeline to prevent these impurities from entering the subsequent equipment and clogging or damaging the equipment. This can protect the normal operation of the equipment and reduce the cost of maintenance and replacement;

[0109] The filter can filter out large particles of impurities in the pipes, purify the water quality, and avoid contaminating the land, lawns, and plants, etc. This can ensure the health of the water body and ensure the growth of plants and lawns.

[0110] In this embodiment, a filter screen is provided on the surface of the low-pressure spray pipe 8 to prevent tiny particles from clogging the low-pressure spray pipe 8 .

[0111] In this solution, the filter screen on the surface of the low-pressure spray pipe 8 can filter out tiny particles in front of the nozzle, preventing these impurities from entering the low-pressure spray pipe 8 and causing blockage or damage to the low-pressure spray pipe 8, thereby protecting the low-pressure spray pipe 8 from the influence of tiny particles and extending the service life of the low-pressure spray pipe 8;

[0112] The filter on the surface of the low-pressure spray pipe 8 can filter out tiny particles in front of the nozzle, preventing these impurities from entering the low-pressure spray pipe 8 and causing blockage or damage to the low-pressure spray pipe 8. It can protect the low-pressure spray pipe 8 from being affected by tiny particles and extend the service life of the low-pressure spray pipe 8;

[0113] The filter on the surface of the low-pressure spray pipe 8 can block the tiny particles in front of the spray head, ensure the uniformity and stability of the water flow, avoid uneven water spraying or poor water permeability, thereby improving the performance of the low-pressure spray pipe 8 and ensuring the water spraying effect;

[0114] The filter on the surface of the low-pressure spray pipe 8 filters out tiny particles in front of the nozzle to prevent these particles from entering the irrigation water source, improve the purity of water quality, and avoid the harm to irrigation caused by tiny particles;

[0115] Setting a filter on the surface of the low-pressure spray pipe 8 can reduce the cost of system maintenance and replacement of the low-pressure spray pipe 8, because if the low-pressure spray pipe 8 is cut off or blocked by tiny particles, frequent replacement will cause the irrigation equipment to be overloaded and lose time costs;

[0116] In summary, providing a filter on the surface of the low-pressure sprinkler pipe 8 can protect the low-pressure sprinkler pipe 8, improve the performance of the low-pressure sprinkler pipe 8, maintain water quality and reduce maintenance costs, and is therefore often used in sprinkler irrigation and waterscape systems.
