Description

Technical Field

[0001] This application relates to the technical field of sliding contact line cleaning devices, and in particular to a cleaning device for sliding contact lines. Background Art

[0002] As an important power supply device, sliding contact lines are widely used in power supply scenarios for various mobile devices. Its working principle is to install carbon brushes on mobile devices, so that the carbon brushes contact and slide on the active wire body to draw electricity.

[0003] The sliding contact line device includes a fixed wire body and a current collector. The wire body is connected to an external power supply to supply power to the copper sheet in the wire body; the current collector includes a spring bracket and a carbon brush. The spring bracket is installed on the mobile device, and the carbon brush is installed at the end of the spring bracket. The carbon brush is composed of a conductor, an insulator housing, and an output cable, and the conductor is formed by die-casting graphite, copper powder, and other components.

[0004] Since the conductor of the carbon brush is in hard contact with the copper sheet in the wire body, during the use of the sliding contact line, the repeated friction between the carbon brush and the wire body will cause the conductor of the carbon brush to become thinner and thinner, and a small amount of worn graphite powder and copper powder are easily left in the wire body groove. Over time, it will become a safety hazard. Therefore, during the use of the sliding contact line device, it is necessary to regularly clean the dust and powder in the wire body groove.

[0005] Chinese Patent with Publication No. CN218216066U discloses a sliding contact line cleaning device, which includes a brush holder for connecting an external mobile device and a brush head installed on the brush holder. The brush holder is provided with an installation groove, and installation positions are respectively opened on two opposite groove walls of the installation groove; the brush head includes a brush head main body that can be inserted into the installation groove and bristles arranged on the brush head main body. Elastic arms are respectively arranged on two opposite sides of the brush head main body. The fixed end of the elastic arm is connected to the brush head main body, and the free end of the elastic arm is provided with a plugging protrusion that can be inserted into the installation position.

[0006] The above-mentioned sliding contact line cleaning device moves along the wire body groove of the sliding contact line device driven by an external mobile device. During the movement, the graphite powder and copper powder in the wire body groove are automatically scraped by the bristles of the brush head. Only by scraping the graphite powder and copper powder in the wire body groove with the bristles, the graphite powder and copper powder will continuously accumulate during the movement of the bristles until they overflow from the wire body groove to other parts in the guide rail, resulting in incomplete cleaning in the sliding contact line guide rail, thereby reducing the use safety and stability of the sliding contact line. Utility Model Content

[0010] By adopting the above technical solution, driven by an external mobile device, the bristles of the cleaning device clean the wire body groove, scrape off the dust, and at the same time, the suction fan works to generate negative pressure, and the cleaned dust is sucked into the dust suction chamber through the dust suction port. The filter screen frame filters the inhaled dust to prevent the dust from entering the suction fan and causing damage; and under the action of the check valve assembly, it effectively prevents the dust adsorbed in the dust suction chamber from pouring out of the dust suction chamber when the suction fan stops working. By using the cooperation of the cleaning brush and the dust suction assembly, the dust in the wire body groove of the sliding contact wire can be efficiently cleaned, the dust spillage is prevented, and the thoroughness and use safety of the internal cleaning of the sliding contact wire guide are improved.

[0011] Optionally, the check valve assembly includes an installation rod arranged at the dust suction port parallel to the length direction of the dust suction chamber, two movable sleeves rotatably sleeved on the installation rod, a guide plate arranged on the side wall of the movable sleeve, and a limiting rod arranged on the side of the guide plate away from the dust suction chamber. The axis of the installation rod coincides with the center line of the length direction of the dust suction port. The two movable sleeves are distributed along the axial direction of the installation rod. The length direction of the limiting rod is perpendicular to the axis of the installation rod. When the guide plates are turned to the end portions where the two limiting rods are opposite to each other and abut against each other, the two guide plates just cover the entire dust suction port.

[0012] By adopting the above technical solution, when the suction fan works to generate negative pressure and sucks the cleaned dust into the dust suction chamber through the dust suction port, the guide plate folds upward along the axis of the installation rod, so that the dust enters the interior of the dust suction chamber; however, in the natural state, the end portions where the two limiting rods are opposite to each other abut against each other, and the two guide plates just block the dust suction port, and the limiting rod can prevent the guide plate from turning downward, so that the channel of the dust suction port forms a one-way flow channel, achieving the effect of effectively preventing the dust adsorbed in the dust suction chamber from pouring out.

[0013] Optionally, an installation through-hole is communicated and penetrated along the length direction of the installation rod on the mounting bracket.

[0014] By adopting the above technical solution, when the cleaning device stops working, the nut is screwed out from the installation rod, then the installation rod can be pulled out, and the guide plate can be removed from the dust suction port, so that the dust accumulated in the dust suction bin can be cleaned from the dust suction port. Timely cleaning of the dust in the dust suction bin helps to improve the cleaning effect of the cleaning device and facilitates regular cleaning and maintenance of the cleaning device.

[0015] Optionally, hanging ears are arranged on the filter screen frame, and elastic hooks matching the hanging ears are arranged on the inner side wall of the dust suction bin. When the filter screen frame is placed in the dust suction bin, the hanging ears are clamped between the elastic hooks and the inner side wall of the dust suction bin.

[0016] By adopting the above technical solution, the arrangement of the hanging ears and the elastic hooks facilitates the installation and disassembly of the filter screen frame, thus providing convenience for cleaning or replacing the filter screen frame.

[0017] Optionally, mounting holes are arranged in the mounting groove communicated with the side wall of the mounting bracket. Insertion protrusions are arranged on the brush head main body to cooperate with the mounting holes. And the brush head main body is made of elastic material. When the brush head main body is inserted into the mounting groove, the insertion protrusions pass through the mounting holes and extend out of the side wall of the mounting bracket, and the insertion protrusions are in insertion fit with the mounting holes.

[0018] By adopting the above technical solution, the cooperation between the insertion protrusions and the mounting holes on the mounting bracket realizes the convenient replacement and fixation of the brush head main body. This design not only improves the installation efficiency of the brush head main body but also extends the service life of the cleaning brush.

[0019] Optionally, a connecting rod is arranged at the end of the spring bracket, and an end block is arranged at the end of the connecting rod. A connecting seat made of elastic material is arranged on the top wall of the mounting bracket far from the bristles, and a limiting groove is correspondingly arranged on the connecting seat for the end block. The end block is in insertion fit with the limiting groove.

[0020] By adopting the above technical solution, the insertion fit between the end block and the limiting groove is utilized to realize the rapid installation between the connecting rod and the mounting bracket, thereby improving the overall stability and service life of the device.

[0021] Optionally, the end block is spherical.

[0022] By adopting the above technical solution, the end block is set in a spherical shape so that the end block can rotate freely in the limit groove, thereby adapting to different angles of the mounting frame, facilitating the adjustment of the inclination angle between the connecting rod and the mounting frame as needed, and increasing the cleaning range of the cleaning device on the inner wall of the guide rail.

[0023] Optionally, the connecting rod sliding sleeve is provided with a positioning cover, and a thread is provided between the inner wall of the positioning cover and the outer wall of the connecting seat. The positioning cover is connected to the connecting seat by threaded rotation, and the inner ring hole of the positioning cover is clamped on the top side wall and end block of the connecting seat.

[0024] By adopting the above technical solution, the mounting frame after the angle is adjusted is fixed by using the positioning cover, thereby reducing the stability of the cleaning device during the cleaning process driven by an external mobile device, thereby improving the cleaning effect of the cleaning device.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. Driven by the external mobile device, the bristles of the cleaning device clean the wire body groove and scrape off the dust. At the same time, the suction fan generates negative pressure and sucks the cleaned dust into the dust suction bin through the dust suction port. The filter frame filters the sucked dust to prevent the dust from entering the suction fan and causing damage. And under the action of the anti-return component, the dust adsorbed in the dust suction bin is effectively prevented from dumping out of the dust suction bin when the suction fan stops working. The combination of the cleaning brush and the dust suction component can efficiently clean the dust in the wire body groove of the busbar and prevent dust from overflowing, which improves the thoroughness and safety of cleaning inside the busbar guide rail.

[0027] 2. When the suction fan generates negative pressure and sucks the cleaned dust into the dust suction bin through the dust suction port, the guide plate is folded upward along the axis of the mounting rod, so that the dust enters the interior of the dust suction bin; however, in a natural state, the opposite ends of the two limit rods conflict with each other, and the two guide plates just block the dust suction port, and the limit rod can prevent the guide plate from flipping downward, so that the channel of the dust suction port forms a one-way flow channel, which effectively prevents the adsorbed dust in the dust suction bin from pouring out; 3. When the cleaning device stops working, unscrew the nut from the mounting rod, pull out the mounting rod, and remove the guide plate from the dust suction port, so that the dust accumulated in the dust suction bin can be cleaned from the dust suction port. Timely cleaning of the dust in the dust suction bin helps to improve the cleaning effect of the cleaning device and facilitates regular cleaning and maintenance of the cleaning device.
