Detailed Implementation
[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0017] An ion fan is a device that neutralizes static electricity on object surfaces by generating positive and negative ions through air ionization. Its working principle combines static neutralization with airflow transport. Figure 1 As shown. The ion fan uses a high-voltage generator (usually DC or AC high voltage) to act on a discharge needle (or wire electrode). When the voltage reaches a certain threshold, the tip of the discharge needle undergoes corona discharge, ionizing the surrounding air molecules and generating a large number of positive and negative ions. Depending on the high-voltage characteristics, the ions can be unipolar or bipolar. For example, in a DC regulated type, positive and negative high voltages are connected to different discharge needles, simultaneously generating positive and negative ions; in an AC high-voltage type, the same discharge needle alternately generates positive and negative ions, with positive ions generated during the positive half-cycle and negative ions during the negative half-cycle; in a pulsed DC type, positive and negative high voltages are periodically output alternately, and the neutralization effect is optimized by adjusting the amplitude and duty cycle. The ionized ions are blown towards the target area by a built-in fan, forming an electrically charged ion wind. When the static electricity on the object surface—such as negative charge—attracts positive ions in the airflow (or vice versa), the charge is neutralized. This process follows the following physical law: opposite charges attract: neutralization occurs when the surface charge of the object and the ions have opposite polarities.
[0018] Based on the above-mentioned principle of static electricity elimination, this embodiment provides a portable static electricity removal device for locomotive components, such as... Figures 2-5As shown, it includes: a panel 6, a housing 1 that is matched and connected to the panel, and an ion generating unit 2, an air supply unit 3, a power supply unit 4 and a control unit 5 disposed in the housing 1; Furthermore, the outer casing 1 has two adjacent sides respectively provided with a magnetic structure 11 for adsorbing the device onto the device to be destaticated and a plurality of air outlets 12 for guiding the airflow direction. The ion generating unit 2 is located on the side near the air outlet and is used to ionize the air to generate ions that can neutralize static electricity. The air supply unit 3 is disposed between the ion generating unit 2 and the power supply unit 4, and is used to blow the ion-rich air generated by the ion generating unit to the outside of the device. The power supply unit 4 is disposed on the end face of the housing opposite to the air outlet 12, and is used to supply power to the ion generating unit 2 and the air supply unit 3. The control unit 5 is disposed opposite to the magnetic mechanism 11, and includes a control circuit board for power management, high voltage generation and motor control.
[0019] Specifically, in this embodiment, a wind speed adjustment knob 61 is provided on the panel 6. The wind speed can be adjusted by rotating the knob according to actual needs.
[0020] Specifically, the core of the control unit is a control circuit board that integrates three core control functions: Power Management: Responsible for managing the power distribution, charge and discharge protection, voltage conversion and power monitoring of the built-in lithium battery, providing a stable and suitable power supply for all components of the device; High-voltage generation: This circuit serves as the driving source for ion generation unit 2. It converts the low-voltage DC power supplied by the battery into the required DC, AC, or pulsed DC high voltage via a boost circuit and outputs it to the high-voltage probe 22 to generate corona discharge and ionize the air. Motor control: Used to drive and control the fan 31 in the air supply unit 3. The fan speed can be adjusted through a circuit (such as a speed control circuit) to control the wind speed. The wind speed adjustment knob 61 is connected to this part of the circuit.
[0021] Specifically, addressing the technical challenges of traditional equipment being bulky, fixed in installation, and difficult to use in flexible and variable scenarios such as locomotive maintenance, this embodiment designs a highly integrated, portable adsorption device that supports modular assembly. Its core design philosophy lies in: decoupling the device from dependence on a fixed power supply and installation location through built-in power supply, magnetic fixation, and modular assembly; optimizing the internal layout to reduce volume through a compact U-shaped support structure; and ensuring that neutralization efficiency is not reduced due to portability through the close proximity of the ion unit and the air outlet. The working principle of this device follows the classic ion fan process of "ionization-transportation-neutralization," with the specific steps as follows: Start-up and power supply: After the device is started, the control unit 5 manages the electrical energy from the power supply unit 4 and provides the required power to the ion generating unit 2 and the air supply unit 3; Ion generation: The control unit 5 drives the ion generation unit 2 to work. The high voltage generator inside generates high voltage DC, AC or pulse DC and loads it onto the discharge needle, causing the tip to corona discharge and ionize the surrounding air molecules, thereby generating a large number of positive and negative ions in the area near the air outlet 12 inside the device. Ion transport: The control unit 5 starts the air supply unit 3 to rotate and generate a directional airflow, which blows out the air rich in positive and negative ions generated by the ion generating unit 2 through several air outlets 12 that can guide the airflow direction, forming an ion wind covering the target area. Static Electricity Neutralization: Aim the device's air outlet at the object or area where static electricity needs to be eliminated, ensuring the ionized airflow covers the target. The ionized airflow blowing towards the target locomotive component will attract positively charged areas (e.g., negatively charged areas) on the component's surface. The ions combine with the surface charge, achieving charge neutralization and thus eliminating static electricity.
[0022] Specifically, during operation, the position and angle of the device can be adjusted in a timely manner according to the static electricity generated to ensure the static electricity removal effect.
[0023] Specifically, this embodiment enables the device to be quickly installed and disassembled by setting up a magnetic structure 11, without the need for a complex fixed bracket. This is very suitable for the mobile operation needs of locomotives when they are being inspected and maintained in different locations. The entire device can also be attached and fixed near the locomotive cabinet or the target component, ensuring that the air outlet 12 is aligned with the area to be treated. This flexible attachment installation method improves the convenience of the work and enhances its adaptability in complex and narrow locomotive component environments.
[0024] Specifically, in this embodiment, the air outlet 12 is arranged adjacent to the ion generating unit 2 to ensure that the ions can be blown out by the airflow with the shortest path and the highest concentration after generation, thereby improving the neutralization efficiency.
[0025] In a specific embodiment, such as Figure 2As shown, the air supply unit 3 includes a fan 31 and a U-shaped support frame 32 for mounting the fan; both ends of the U-shaped support frame 32 are fixed to both sides of the power supply unit 4, and the ion generating unit 2 is provided on its end face near the air outlet; both ends of the fan 31 are rotatably connected to the U-shaped support frame 32.
[0026] Specifically, the U-shaped support frame 32 is integrally formed by bending process, and the opening of the U-shape faces the power supply unit. The opening width is greater than the length of the axial flow fan 31 so as to accommodate the axial flow fan.
[0027] Specifically, the U-shaped support frame 32 includes a mounting plate and two bearing seat mounting plates located at both ends of the mounting plate. The bearing seat mounting plates have several connection holes, which are fixedly connected to studs located inside the housing by screws. An insulating plate 21 is fixedly mounted on the mounting plate, and the bearing seat mounting plates are equipped with bearing seats for mounting the axial flow fan.
[0028] Specifically, the U-shaped structure has higher bending and torsional stiffness. When the fan vibrates at high speed, the U-shaped support frame can effectively absorb vibration energy, prevent the support from deforming or resonating, and ensure the long-term reliability of the equipment.
[0029] In a specific embodiment, such as Figure 6 and Figure 7 As shown, of the two opposite end faces of the housing 1, one end face is provided with a snap-fit seat 13 and a first connector 14, and the other end face is provided with a snap-fit 15 that matches the snap-fit seat and a second connector 16 that matches the first connector.
[0030] Specifically, this embodiment allows for the free assembly of multiple identical static electricity removal devices by setting matching buckles and buckle seats at both ends of the outer shell. Based on the characteristics of the object to be statically removed and the available operating space, a suitable length of static electricity removal device is selected. Then, the portable static electricity removal device is attached to the cabinet or around the object to be removed using a strong electromagnet. If the equipment is large, multiple portable static electricity removal devices can be assembled into a unit of sufficient length to effectively remove static electricity. After the static electricity removal work is completed, the multiple static electricity removal devices can be disassembled, saving space and meeting the needs of various scenarios.
[0031] Specifically, the first connector 14 is a female connector, embedded in a recessed groove on the end face of the housing 1. Its contacts are defined as positive power supply, negative power supply, fan control signal line, and ion generator enable signal line. When the two devices are physically locked to the latch seat 13 via the latch 15, the connectors automatically mate and become conductive, as shown below. Figure 8As shown. This design allows multiple devices to be automatically connected to form a system powered and controlled by a single main unit, eliminating the need for external wiring. This truly achieves plug-and-play modular expansion and resolves the conflict between the need for large-scale electrostatic elimination and portability.
[0032] Specifically, the buckle and buckle holder shown in this embodiment are conventional connection structures, and will not be described in detail here. Furthermore, since this device can be used with magnetic adsorption, the magnetic structure, buckle, and buckle holder ensure a stable connection.
[0033] In a specific embodiment, the ion generating unit 2 includes an insulating plate 21, a grounding electrode mounted on the insulating plate, and several high-voltage probes 22. Specifically, the several high-voltage probes are arranged at equal intervals and soldered to the circuit traces on the insulating plate. The grounding electrode is an annular copper strip surrounding the high-voltage probe array. This needle-ring electrode structure, combined with a specific high-voltage pulse driving circuit, can generate a uniformly distributed ion cloud with low power consumption.
[0034] In a specific embodiment, the fan 31 is an axial flow fan.
[0035] Specifically, in this embodiment, the axial flow fan is rotatably connected to the bearing seats at both ends of the U-shaped support frame 32 via miniature ball bearings.
[0036] In a specific embodiment, the power supply unit 4 is a lithium battery.
[0037] Specifically, this embodiment incorporates a built-in lithium battery as a power supply unit, freeing the device from dependence on an external power cord and further enhancing its portability and operational capabilities in different field environments.
[0038] In a specific embodiment, the magnetic structure 11 is an electromagnet.
[0039] Specifically, in this embodiment, a groove matching the shape of the electromagnet is formed on the outer wall of the outer casing 1. The electromagnet is embedded in the groove and secured with high-strength structural adhesive to prevent displacement. Its on / off state is managed by the control unit 5. Under normal conditions, it is de-energized and relies on a permanent magnet for attraction; when rapid release is required, energization generates a reverse magnetic field to counteract the magnetic force. This design is particularly suitable for scenarios requiring frequent device movement.
[0040] Specifically, the device described in this embodiment requires maintenance and upkeep, including: Cleaning and maintenance: Clean the air outlet, high-pressure probe and other components of the device regularly (e.g., monthly) to remove dust and oil stains and prevent debris from affecting ion output and static electricity removal effect; Performance testing: Use an electrostatic discharge tester to regularly (e.g., quarterly) test the device's static discharge effect, and repair it promptly if any abnormalities are found; Power off and shut down: If the device will not be used for an extended period, the power should be turned off and the equipment should be protected from dust.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
