[0033] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0034] like Figure 1As shown, an embodiment of the present invention provides a portable cleaning device. The portable cleaning device includes a mobile vehicle 1, a scrubbing system 2, a water supply system 3, and a drug supply system 4. The water supply system 3 and the drug supply system 4 are both mounted on the mobile vehicle 1, and the scrubbing system 2 is connected to the water supply system 3 and the drug supply system 4. This allows for easy movement of the mobile vehicle 1, allowing cleaning personnel to clean various parts of the railway vehicle using the scrubbing system 2. The water supply system 3 includes a water supply tank 31, a first pipeline 32, and a second pipeline 33. The drug supply system 4 includes a drug supply tank 41 and a third pipeline 42. One end of the first pipeline 32 is connected to the water supply box 31, and the other end is connected to the washing system 2, and a first control valve 321 is provided on the first pipeline 32; one end of the second pipeline 33 is connected to the first pipeline 32 and is located between the water supply box 31 and the first control valve 321, and the other end is connected to the output end of the medicine supply box 41, and a second control valve 331 is provided on the second pipeline 33, one end of the third pipeline 42 is connected to the output end of the medicine supply box 41, and the other end is connected to the washing system 2.

[0035] By controlling the on / off states of first control valve 321 and second control valve 331, the portable cleaning device operates in both a clean water mode and a mixed detergent mode. When the exterior of a railway vehicle is lightly soiled, the portable cleaning device uses the clean water mode to conserve detergent. When the exterior of the railway vehicle is heavily soiled and cleaning becomes more difficult, the portable cleaning device uses the mixed detergent mode to improve cleaning effectiveness.

[0036] Specifically, when the portable cleaning device adopts the clean water mode, the first control valve 321 is opened and the second control valve 331 is closed, and the liquid in the water supply tank 31 flows through the first control valve 321 through the first pipe 32 and then enters the washing system 2; when the portable cleaning device adopts the mixed cleaning agent mode, the first control valve 321 is closed and the second control valve 331 is opened, and the liquid in the water supply tank 31 flows through the second control valve 331 through the first pipe 32, and then flows through the output end of the medicine supply box 41 through the second pipe 33 to enter the third pipe 42. The output end of the medicine supply box 41 outputs the cleaning agent, and the liquid in the water supply tank 31 takes the cleaning agent away into the washing system 2 when passing through the output end of the medicine supply box 41.

[0037] The portable cleaning device is flexible and easy to use, and can clean various parts of railway vehicles, effectively reducing manual fatigue. The portable cleaning device has two cleaning modes, which improves practicality. The two cleaning modes can be used in a variety of ways. For example, after using the mixed cleaning agent mode to clean the railway vehicle, the clean water mode is used to clean the railway vehicle, which can effectively remove the cleaning agent on the railway vehicle, prevent the cleaning agent from corroding the railway vehicle, and achieve a better cleaning effect.

[0038] To achieve automated control of the portable cleaning device, the portable cleaning device also includes a control system 5. The control cabinet of the control system 5 is mounted on the mobile vehicle 1, and a control switch 51 is mounted on the scrubbing system 2. The control cabinet and the control switch 51 are connected via a control line 52. When cleaning the railway vehicle, the clean water mode or the mixed detergent mode is selected on the control switch 51 as needed, that is, the first control valve 321 and the second control valve 331 are controlled by the control switch 51. Furthermore, a cable reel is provided in the control cabinet, and one end of the control line 52 is wound around the cable reel, and the other end is connected to the control switch 51. When the scrubbing system 2 is pulled, the control line 52 drives the cable reel to rotate, thereby extending the control line 52. When cleaning is completed, the control line 52 is wound around the cable reel, thereby extending or shortening the control line 52.

[0039] Optionally, the scrubbing system 2 is connected to the first pipeline 32 and the third pipeline 42 through the fourth pipeline 6. Figure 1 The end of the third pipeline 42 facing away from the output end of the medicine supply box 41 is connected to the first pipeline 32, and the connection point between the third pipeline 42 and the first pipeline 32 is located after the first control valve 321. The mobile body 1 is provided with a double-end joint 11, the first pipeline 32 is connected to one end of the double-end joint 11, and the fourth pipeline 6 is connected to the other end of the double-end joint 11, so as to achieve communication between the washing system 2 and the first pipeline 32 and the third pipeline 42 through the fourth pipeline 6. Furthermore, in order to achieve the extension and contraction of the fourth pipeline 6, the fourth pipeline 6 is a spring tube, which facilitates the extension and contraction of the washing system 2 for cleaning over a wider range.

[0040] It is understood that the portable cleaning device further comprises a power system 7, which provides power for the entire device. Specifically, the power system 7 comprises a battery and a charger, wherein the battery provides power for the entire device and the charger is used to charge the battery.

[0041] Optionally, continue with reference to Figure 1 A water pump 322 is provided on the first pipeline 32 , and the water pump 322 can provide power for the liquid in the water supply box 31 to flow toward the washing system 2 .

[0042] In order to make the concentration of the cleaning agent output from the output end of the drug supply system 4 adjustable, specifically, continue to refer to Figure 1 The drug supply system 4 further includes a metering pump 43, which is disposed at the output end of the drug supply box 41. One end of the metering pump 43 is connected to the second pipe 33, and the other end is connected to the third pipe 42. It is understood that when the cleaning effect of the mixed cleaning agent mode is not good, the metering pump 43 can be adjusted to change the dosage of the cleaning agent output from the drug supply box 41 to adjust the concentration to achieve a better cleaning effect.

[0043] To prevent impurities in the liquid in the water supply tank 31 from affecting the accuracy of the metering pump 43, a filter 332 is provided on the second pipeline 33, and the filter 332 is located between the second control valve 331 and the metering pump 43. When the second control valve 331 is open and the first control valve 321 is closed, the liquid in the water supply tank 31 flows through the first pipeline 32, the second control valve 331, into the second pipeline 33, and then is filtered by the filter 332 before entering the metering pump 43.

[0044] Specifically, continue to refer to Figure 1 In order to prevent the liquid in the water supply tank 31 from flowing back into the medicine supply tank 41 in the clean water mode, a one-way valve 421 is provided on the third pipeline 42. The one-way valve 421 is located downstream of the metering pump 43. The one-way valve 421 can conduct in one direction, that is, in the mixed detergent mode, the one-way valve 421 conducts in the forward direction, and in the clean water mode, the one-way valve 421 is blocked in the reverse direction.

[0045] Specifically, to ensure that the liquid in the water supply tank 31 remains within a certain range, the water supply system 3 also includes a water injection joint 34, a first liquid level sensor 35, and a second liquid level sensor 36. The water injection joint 34 is located between the water supply tank 31 and an external water source, allowing the external water source to inject liquid into the water supply tank 31 through the water injection joint 34. A third control valve 341 is provided on the water injection joint 34 to control the on / off state of the water injection joint 34. Both the first liquid level sensor 35 and the second liquid level sensor 36 are located on the water supply tank 31, with the first liquid level sensor 35 positioned above the second liquid level sensor 36. The working process is: when the height of the liquid in the water supply tank 31 triggers the second liquid level sensor 36, it means that the liquid in the water supply tank 31 is at a low liquid level and liquid needs to be injected. The control system 5 controls the third control valve 341 to open, and the external water source can flow liquid into the water supply tank 31; when the height of the liquid in the water supply tank 31 triggers the first liquid level sensor 35, it means that the liquid in the water supply tank 31 is at a high liquid level, and the control system 5 controls the third control valve 341 to close to prevent liquid from the external water source from flowing in.

[0046] Furthermore, a drain valve 311 is provided at the bottom of the water supply tank 31 . When the liquid in the water supply tank 31 needs to be drained, the drain valve 311 is opened to complete the drainage operation.

[0047] Continue to refer to Figure 1 , now combined Figure 1 The structure of the scrubbing system 2 will be described in detail.

[0048] The scrubbing system 2 includes an operating rod 21, a mounting cover 22, a brush 23, and a nozzle 24. The operating rod 21 is a hollow structure and is connected to the fourth pipe 6. Liquid or a mixed cleaning agent enters the operating rod 21 through the fourth pipe 6, and the nozzle 24 is connected to the operating rod 21. Therefore, the liquid or mixed cleaning agent is ultimately sprayed out through the nozzle 24. The mounting cover 22 is rotatably mounted on the end of the operating rod 21 that is away from the fourth pipe 6. The brush 23 and the nozzle 24 are both mounted on the mounting cover 22. When cleaning a railway vehicle, the nozzle 24 sprays liquid or a mixed cleaning agent, and the brush 23 is used to clean stains. The mounting cover 22 can rotate relative to the operating rod 21 so that the brush 23 has multiple angles, ensuring the contact area between the brush 23 and the railway vehicle and improving cleaning efficiency.

[0049] To further increase the maximum cleaning distance of the operating rod 21, the operating rod 21 is a retractable structure, which includes a first rod 211 and a second rod 212. The first rod 211 is slidably disposed in the second rod 212. When the operating rod 21 needs to be extended for cleaning, the first rod 211 is pulled out to increase the length of the operating rod 21; when the operating rod 21 needs to be shortened for storage, the first rod 211 can be retracted into the second rod 212 to reduce the length of the operating rod 21 for easier storage.

[0050] Furthermore, the operating rod 21 also includes a locking member 213. When the first rod 211 is adjusted relative to the second rod 212, the locking member 213 can lock the relative position of the first rod 211 and the second rod 212 to improve stability and enhance cleaning efficiency.

[0051] Specifically, a fixing plate 2111 is provided at the end of the first rod 211 facing away from the fourth conduit 6. The fixing plate 2111 is provided with a hollow cavity that communicates with the hollow structure of the operating rod 21. The fixing plate 2111 is provided with a connection port that communicates with the hollow cavity. One end of the output conduit 25 is connected to the connection port, and the other end is connected to the nozzle 24, so that liquid can be sprayed from the output conduit 25 through the nozzle 24. Furthermore, a bracket 2112 is provided at the end of the fixing plate 2111 facing away from the first rod 211. The bracket 2112 is hingedly connected to the mounting cover 22 to enable the mounting cover 22 to rotate relative to the operating rod 21.

[0052] Furthermore, the nozzles 24 and the output pipes 25 are arranged in a one-to-one correspondence, with two of each being provided. Two connecting ports are provided on the fixed plate 2111. One end of the two output pipes 25 is respectively connected to the two connecting ports, and the other end is respectively connected to the two nozzles 24 to improve the cleaning effect.

[0053] To make cleaning more convenient and improve the cleaning effect, the scrubbing system 2 also includes a drive device 26, which can drive the brush 23 to rotate, reducing the fatigue of the cleaning staff and improving the cleaning effect. Furthermore, the drive device 26 includes a motor and a connector. The motor is mounted on the mounting cover 22, and the brush 23 is connected to the output end of the motor via the connector. The motor can drive the brush 23 to rotate.

[0054] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here.
