[0040] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0041] Example 1

[0042] Figure 1 This is a schematic diagram of an overall system of a portable dust removal device for electric locomotives according to an exemplary embodiment, the device comprising:

[0043] Dual-function dust removal mechanism and controller 1;

[0044] The dual-function dust removal mechanism is used to perform either dust removal or dust suction functions;

[0045] The dual-function dust removal mechanism includes a dust removal device and a dust collection device;

[0046] The dust removal device includes: a compressor, an air tank, and a dust removal pipeline;

[0047] The compressor is used to compress air and store it in the air tank, and the outlet of the air tank is connected to the initial end of the dust removal pipeline;

[0048] A solenoid valve 2 is provided between the outlet of the gas storage tank and the initial end of the dust removal pipeline, and the solenoid valve 2 is connected to the controller 1;

[0049] The dust collection device includes: a fan 3, a dust collection pipe, and a dust collection bin;

[0050] The exhaust end of the exhaust fan 3 is connected to the initial end of the dust collection pipe, and the other end of the exhaust fan 3 is connected to the inlet of the dust collection bin; the exhaust fan 3 is connected to the controller 1.

[0051] The controller 1 is used to send control commands to the solenoid valve 2 or the exhaust fan 3 to start the dust removal device or the dust collection device.

[0052] Understandably, this application solves the dust removal problem in the confined space of locomotives by providing a switchable dust removal / vacuuming dual-mode system. The dust removal device consists of a compressor, an air tank, and a dust removal pipeline. The compressor uses mechanical or electric motors to drive pistons or blades to compress gas to a certain pressure and store it in the air tank. When dust removal is required, the user presses the dust removal switch button on the device. The controller 1 then sends high and low level signals to the solenoid valve 2, opening it. Once the solenoid valve 2 is open, compressed air enters the dust removal pipeline from the air tank via the solenoid valve 2. The compressed air is then discharged through the outlet at the end of the dust removal pipeline. The compressed air is sprayed at high speed onto the surface of the equipment that needs cleaning. Due to its high kinetic energy and impact force, the dust attached to the surface of the equipment can be blown away. In order to prevent the dust from slowly falling and continuing to accumulate, the user can turn on the dust collection switch on the dust removal device. After receiving the signal, the controller 1 sends high and low level signals to the exhaust fan 3, and the exhaust fan 3 starts to run. The suction generated by the exhaust fan 3 draws the dust into the dust collection pipe through the air inlet and finally into the dust collection bin. This realizes the automatic collection of dust and avoids the problem that the dust is only swept from the upper parts to the lower parts or falls on the floor without being completely removed from the locomotive.

[0053] Preferably, it further includes:

[0054] Power supply module 4, which is used to supply power to the controller 1, compressor, solenoid valve 2 and exhaust fan 3;

[0055] The power supply module 4 uses a lithium battery pack;

[0056] It is understood that the power supply module 4 in this embodiment uses a modular battery pack with 6 18650 lithium cells (3S2P arrangement) and supports quick replacement; the battery pack has a range of ≥45 minutes (and is also compatible with the M12 fast charging protocol).

[0057] Preferably,

[0058] The gas storage tank is equipped with a gas pressure detection device 5, which is used to detect the internal pressure of the gas storage tank.

[0059] The compressor is electrically connected to the power supply module 4 via a pressure switch 6, and the pressure switch 6 is also connected to the air pressure detection device 5.

[0060] The pressure switch 6 is used to turn on itself when the internal pressure of the compressor is lower than a preset pressure threshold, so that the power supply module 4 can supply power to the compressor.

[0061] Understandably, a pressure detection device 5 is installed inside the gas storage tank. This device effectively detects pressure changes within the tank. The pressure switch 6 compares the real-time pressure detected by the device with a set pressure value. When the detected pressure is lower than the set value, the pressure switch is activated, allowing the power supply module 4 to supply power to the compressor. This starts the compressor, increasing the compressed air content inside the tank and thus increasing the pressure. This achieves automatic air replenishment. Simultaneously, the pressure switch 6 can also disconnect when the pressure reaches or exceeds the set value. In this case, the power supply module 4 cannot supply power to the compressor, causing it to lose power and stop working, thereby preventing excessive pressure inside the tank from causing safety accidents.

[0062] Preferably,

[0063] The dust collection bin is a cyclone dust collection bin, which is detachably connected to the exhaust fan 3;

[0064] The dust collection bin is equipped with a dust sensor 7, which is connected to the controller 1. The controller 1 is also connected to an alarm device 8, which is used to trigger an alarm when the dust inside the cyclone dust collection bin reaches a set thickness.

[0065] It is understood that the integrated dust collector in this embodiment adopts a cyclone dust collector, which has the following advantages: the cyclone dust collector has a simple structural design with no complex moving parts, making maintenance very convenient and reducing maintenance costs; it separates dust from gas through centrifugal force, with a separation efficiency of over 90%, and can handle gas flow rates of hundreds of cubic meters per hour, resulting in high processing efficiency and low energy consumption; the cyclone dust collector can effectively reduce dust pollution, protect the environment, and meet environmental protection requirements; the cyclone dust collector is widely used in industries such as steel, cement, chemical, mining, and power, and is suitable for various dust treatment scenarios; the cyclone dust collector is inexpensive, easy to install, requires no special construction work, and does not require replacement of any filter materials, with no additional costs after a one-time investment; the cyclone dust collector can withstand temperatures up to 400℃, and with the use of special materials, it can withstand even higher temperatures; the cyclone dust collector can be dry-cleaned, which is beneficial for recovering valuable dust.

[0066] A dust sensor 7 is installed inside the cyclone dust collection bin to detect the thickness of the dust. When the dust thickness inside the cyclone dust collection bin reaches the set thickness, it indicates that the bin is almost full and needs to be cleaned. Therefore, when the dust sensor 7 detects that the dust thickness has reached the set value, the controller 1 will send a start signal to the alarm device 8 to remind the user to clean the dust in the dust collection bin. The alarm device 8 can be one or more of the following: light color alarm, voice alarm, vibration alarm.

[0067] Preferably,

[0068] The dust removal duct is equipped with a rotatable air outlet at its end, and the air outlet of the dust removal duct adopts a tapered Venturi structure.

[0069] Understandably, in this embodiment, the air outlet adopts a tapered Venturi structure (throat diameter 10mm), and the wind speed can reach 25m / s. The rotatable air outlet design allows users to easily adjust the blowing angle as needed to meet different dust blowing requirements. It can more flexibly adapt to different working environments and layout requirements, whether it is straight discharge or need to bypass obstacles, it can be easily achieved. By adjusting the direction of the air outlet, the airflow path can be controlled more precisely to ensure that dust and exhaust gas can be effectively collected and treated, which helps to improve dust removal efficiency and reduce the risk of dust leakage and secondary pollution.

[0070] Preferably,

[0071] The vacuum pipe is made of a retractable PVC hose, and a flat vacuum head is provided at the end of the vacuum pipe.

[0072] Understandably, the retractable PVC hose offers high flexibility, adapting to various complex cleaning environments. Whether it's narrow gaps or irregular equipment layouts, the retractable hose can easily navigate through them, providing greater operational freedom. The PVC material boasts excellent wear resistance, oil and acid resistance, and flame retardant properties, ensuring it remains in good condition over extended use and reducing maintenance needs. The flat suction head design allows for better contact with the ground and equipment surfaces, especially crevices and corners, resulting in a more thorough cleaning. Its 360-degree rotation function makes the cleaning process more flexible and efficient.

[0073] Preferably,

[0074] The cyclone integrated barrel is also equipped with a stainless steel washable filter element.

[0075] Understandably, stainless steel washable filter cartridges offer high-efficiency filtration, capturing more dust and impurities to ensure effective dust collection. These cartridges typically feature a porous design to block fine particles and maintain air cleanliness. Because they are washable, users can easily clean the cartridges, extending their lifespan. Cleaning simply involves rinsing gently with water and then air drying, reducing the frequency and cost of filter replacements. The stainless steel material makes the cartridges more durable, able to withstand multiple washes and reuses without damage, further minimizing the inconvenience and expense of frequent filter changes.

[0076] Preferably, it further includes:

[0077] The power detection module 9 and the display screen 10 are respectively connected to the controller 1; the controller 1 is also used to receive the remaining power data sent by the power detection module 9 and display it on the display screen 10.

[0078] It is understandable that, since the power supply module 4 in this embodiment uses a lithium battery pack instead of being connected to an external power source, in order to prevent the device from stopping blowing and vacuuming due to insufficient power during use, this embodiment also sets up a power detection module 9 for the lithium battery pack and displays the remaining power on the display screen 10. At the same time, it can also be combined with the alarm device 8 mentioned above to activate the alarm function when the power is low, further reminding the user to charge or replace the battery pack in time.
