Description

Technical Field

[0001] The present invention relates to the technical field of direct current charging gun cleaning, and in particular to a direct current charging gun quick cleaning device and a cleaning method. Background Art

[0002] At present, many new energy charging devices are used outdoors, generally built on parking lots. During actual operation, dust, branches and other debris will inevitably enter, causing the inside of the gun head to be unclean. At the same time, with the continuous use of the charging gun, the surface of the pin will be worn and oxidized, resulting in the charging gun and the vehicle being unreliably connected and unable to charge. Because the DC charging gun has many holes inside and is used outdoors, this provides conditions for the accumulation of debris, and many existing cleaning methods are manual cleaning, which is not only inefficient, but also increases the cleaning time over time. In addition, manual cleaning is prone to dead corners, resulting in insufficient cleaning, and rework is required later, which may even affect the safety and efficiency of later use. In addition, multiple charging ports cannot be cleaned at the same time during cleaning, which will increase the cost of the cleaning process. Summary of the invention

[0016] A method for cleaning and using a DC charging gun quick cleaning device comprises the following steps:

[0017] Step 1: When cleaning the charging end of the charging gun, move the charging end to the inside of the docking frame head, so that the charging end contacts the bottom end of the cleaning tube, and the cleaning sleeve contacts the outside of the charging end. During the movement, the cleaning tube moves to the position of the charging hole and moves to the inside of the charging hole. When it does not contact the charging hole, the movement of the charging end pushes the cleaning tube to move, and pushes the movable ejector rod to move into the inner cavity of the mounting tube. When the movable ejector rod slides in the inner cavity of the mounting tube, the reset spring is squeezed. Later, the movable ejector rod and the cleaning tube are reset by the squeezed reset spring. When the cleaning tube and the cleaning sleeve move to the inside of the charging hole, the brush strip at the end of the cleaning sleeve is wrapped around the outside of the pin, and the single-phase motor is started to drive the rotating rod to rotate, and the transmission wheel is driven to rotate by the rotating rod. Since a rotating belt is installed between the transmission wheel and the outside of the rotating small wheel, The rotating wheel will be driven to rotate, and when the rotating wheel rotates, the installation cylinder will be driven to rotate, which will drive the movable ejector rod, the installation ring block, the cleaning tube and the cleaning sleeve to rotate and clean inside the charging hole, and the cleaning sleeve located inside the charging hole will not contact and clean one side of the charging end. In the process of cleaning the charging gun, not only the charging holes of the charging gun can be cleaned at the same time, which improves the efficiency of the cleaning process, but also the charging guns with different numbers of charging holes can be cleaned, which increases the scope of application of the cleaning process, avoids the need to clean different charging holes in turn when cleaning the charging gun, prolongs the cleaning time, reduces the cleaning efficiency, and avoids the inability to clean charging guns with different numbers of charging holes, which will increase the limitations of the cleaning process and further improve the efficiency of the cleaning work;

[0018] Step 2: When the rotating rod rotates, it drives the transmission wheel to rotate. Since a transmission belt is installed between the transmission wheel and the rotating disk, it drives the rotating disk to rotate. When the rotating disk rotates, it drives the pushing cone block to rotate. When the pushing cone block rotates, it contacts the inclined surface of the moving inclined block, and then drives the moving inclined block to move downward. The moving inclined block drives the mounting plate to move downward, and drives the rotating block to move downward, so that the extrusion airbag is squeezed, and the air is transported to the inside of the cleaning tube through the connecting hose and the air hole, and finally the air is sprayed out through the circular air hole and sprayed into the inside of the charging hole, and the dust inside the charging hole and the cleaned dirt are blown to the outside of the charging hole. When the rotating disk rotates, it drives the turbofan head to rotate, and in the guide Airflow is formed in the inner cavity of the frame head, and the airflow is transported to the inside of the annular cavity through the connecting air pipe. The air inside the annular cavity is ejected through the air jet hole, and the ejected air cleans the outside of the charging gun. Through the two-way air jet treatment, dust, debris and oxides entering the charging gun can be treated at the same time. The inside and outside of the charging hole can be treated at the same time, which increases the adequacy of the treatment process and avoids the accumulation of tiny dirt inside the charging hole that cannot be cleaned during long-term use. In the later treatment, light friction treatment is used, resulting in incomplete treatment and the need for rework. It can also avoid the separate treatment of the outside of the charging gun and the inside of the charging hole, which increases the time and cost of treatment.

[0019] Step three: When the cleaning tube and the cleaning sleeve rotate for cleaning, if there is adhesive dirt inside the charging hole or on the end face of the charging gun, the friction force received by the cleaning sleeve and the cleaning tube when they rotate is too large, which will cause the cleaning tube to twist and drive the push piece to move inside the movable recess. When the push piece moves in the inner cavity of the movable recess, it squeezes the fixed spring. Later, the push piece and the cleaning tube are reset by the fixed spring after squeezing. When the cleaning tube and the cleaning sleeve are subject to too much resistance, the push piece will contact the pressure controller and activate the alarm inside the control panel. Through the alarm with the corresponding number, the operator can promptly discover the problem of the charging gun and deal with it at the first time, avoiding hidden dangers inside the charging gun. If they cannot be discovered and dealt with in time, it will lead to abnormal use later.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention can not only clean the charging holes of the charging gun at the same time through the telescopic cleaning mechanism during cleaning, thereby improving the efficiency of the cleaning process, but also can clean the charging guns with different numbers of charging holes, thereby increasing the scope of application of the cleaning process, thereby avoiding the need to clean different charging holes in sequence when cleaning the charging gun, thereby prolonging the cleaning time and reducing the cleaning efficiency, and also avoiding the inability to clean charging guns with different numbers of charging holes, thereby increasing the limitations of the cleaning process, and further improving the efficiency of the cleaning work, thereby effectively and quickly cleaning the inside of the charging gun head and simultaneously cleaning the plug pins. Since the charging gun is used frequently, its plug pins are conductive components. During long-term use, the column head will be contaminated and oxidized, resulting in increased contact resistance, heat generation during charging, and in severe cases, burning of the gun head or the vehicle;

[0022] 2. The present invention activates the deep cleaning mechanism and the external treatment mechanism through the telescopic cleaning mechanism, and through the two-way jet treatment, the dust, debris and oxides entering the charging gun can be treated at the same time inside the charging port and outside the charging gun, thereby increasing the adequacy of the treatment process and avoiding the situation that tiny dirt is accumulated inside the charging port and cannot be cleaned during long-term use, and light friction treatment is used in the later treatment, resulting in incomplete treatment and the need for rework. In addition, it can also avoid the separate treatment of the outside of the charging gun and the inside of the charging port, which increases the time and cost of the treatment;

[0023] 3. When an abnormal situation occurs through the abnormal detection mechanism of the present invention, the alarm inside the control panel is activated. Through the alarm with the corresponding label, the operator can promptly discover the problem of the charging gun and deal with it at the first time, avoiding hidden dangers inside the charging gun. If it cannot be discovered and dealt with in time, it will lead to abnormal use later. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] The specific implementation is as follows: when the cleaning tube 302 and the cleaning sleeve 301 rotate for cleaning, if there is adhesive dirt inside the charging hole or on the end face of the charging gun, the friction force encountered by the cleaning sleeve 301 and the cleaning tube 302 when they rotate is too large, which will drive the cleaning tube 302 to twist and drive the push piece 603 to move inside the movable recess 602. When the push piece 603 moves in the inner cavity of the movable recess 602, it squeezes the fixed spring 606. Later, the squeezed fixed spring 606 drives the push piece 603 and the cleaning tube 302 to reset. When the cleaning tube 302 and the cleaning sleeve 301 encounter too much resistance, the push piece 603 will contact the pressure controller 605 and activate the alarm inside the control panel. Through the alarm with the corresponding number, the operator can promptly discover the problem of the charging gun.

[0052] The specific implementation method is as follows: when cleaning several charging guns at the same time, the fixing frame 2 and the docking frame head 1 are installed on the outside of the external fixing rod through the docking ring sleeve 9.

[0053] Embodiment 2

[0054] A method for cleaning and using a DC charging gun quick cleaning device comprises the following steps:

[0055] Step 1: When cleaning the charging end of the charging gun, move the charging end to the inside of the docking frame head 1, so that the charging end contacts the bottom end of the cleaning tube 302, and the cleaning sleeve 301 contacts the outside of the charging end. During the movement, the cleaning tube 302 moves to the position of the charging hole and moves to the inside of the charging hole. When it does not contact the charging hole, the cleaning tube 302 is pushed to move by the movement of the charging end, and the movable ejector rod 304 is pushed to move toward the inner cavity of the mounting tube 305. When the movable ejector rod 304 slides in the inner cavity of the mounting tube 305, the reset spring 306 is squeezed. Later, the reset spring 306 after squeezing drives the movable ejector rod 304 and the cleaning tube 302 to reset. When the cleaning tube 302 and the cleaning sleeve 301 move to the inside of the charging hole, the brush strip at the end of the cleaning sleeve 301 is wrapped around the outside of the pin, and the single-phase motor 307 is started to drive the rotating rod 310 to rotate, and the transmission wheel 309 is driven to rotate by the rotating rod 310. A rotating belt 311 is installed between the outer parts of the wheel 312, which will drive the rotating small wheel 312 to rotate. When the rotating small wheel 312 rotates, it drives the installation cylinder 305 to rotate, which will drive the movable top rod 304, the installation ring block 604, the cleaning tube 302 and the cleaning sleeve 301 to rotate, and drive the cleaning sleeve 301 to rotate inside the charging hole for cleaning, and the cleaning sleeve 301 located inside the charging hole is not in contact with one side of the charging end for cleaning. In the process of cleaning the charging gun, not only can the charging holes of the charging gun be cleaned at the same time, improving the efficiency of the cleaning process, but also the charging guns with different numbers of charging holes can be cleaned, increasing the scope of application of the cleaning process, avoiding the need to clean different charging holes in turn when cleaning the charging gun, prolonging the cleaning time and reducing the cleaning efficiency, and avoiding the inability to clean charging guns with different numbers of charging holes, which will increase the limitations of the cleaning process and further improve the efficiency of the cleaning work;

[0056] Step 2: When the rotating rod 310 rotates, it drives the transmission wheel 402 to rotate. Since the transmission belt 404 is installed between the transmission wheel 402 and the rotating disk 405, the rotating disk 405 is driven to rotate. When the rotating disk 405 rotates, it drives the pushing cone block 406 to rotate. When the pushing cone block 406 rotates, it contacts the inclined surface of the moving inclined block 407, and then pushes the moving inclined block 407 to move downward. The moving inclined block 407 drives the mounting plate 408 to move downward, and drives the rotating block 411 to move downward, so that the extrusion airbag 403 is squeezed, and the air is transported to the inside of the cleaning tube 302 through the connecting hose 401 and the air hole, and finally the air is sprayed out through the circular air hole and sprayed into the inside of the charging hole, and the dust inside the charging hole and the dirt cleaned up are blown to the outside of the charging hole. When the moving disk 405 rotates, the turbofan head 503 is driven to rotate, and an airflow is formed in the inner cavity of the guide frame head 504, and the airflow is transported to the inside of the annular cavity 501 through the connecting air pipe 502, and the air inside the annular cavity 501 is ejected through the jet hole, and the ejected air and the outside of the charging gun are cleaned, and the dust, debris and oxides entering the inside of the charging gun are processed by two-way jet processing, and the inside and outside of the charging port can be processed at the same time, which increases the adequacy of the processing process, and avoids the accumulation of tiny dirt inside the charging port during long-term use. It cannot be cleaned, and light friction treatment is used in the later treatment, resulting in incomplete treatment, and rework is required, and it can also avoid the separate treatment of the outside of the charging gun and the inside of the charging port, which increases the processing time and cost;

[0057] Step three: When the cleaning tube 302 and the cleaning sleeve 301 rotate for cleaning, if there is adhesive dirt inside the charging hole or on the end face of the charging gun, the friction force encountered by the cleaning sleeve 301 and the cleaning tube 302 when they rotate is too large, which will drive the cleaning tube 302 to twist and drive the push piece 603 to move inside the movable recess 602. When the push piece 603 moves in the inner cavity of the movable recess 602, it squeezes the fixed spring 606. Later, the squeezed fixed spring 606 drives the push piece 603 and the cleaning tube 302 to reset. When the cleaning tube 302 and the cleaning sleeve 301 are subjected to too much resistance, the push piece 603 will contact the pressure controller 605 and activate the alarm inside the control panel. Through the alarm with the corresponding number, the operator can promptly discover the problem of the charging gun and deal with it at the first time, avoiding the hidden dangers inside the charging gun. If they cannot be discovered and dealt with in time, it will lead to the inability to use it normally later.

During the movement, the cleaning tube (302) moves to the position of the charging hole and moves to the inside of the charging hole. When the charging hole is not contacted, the movement of the charging end pushes the cleaning tube (302) to move, and pushes the movable push rod (304) to move toward the inner cavity of the installation tube (305). When the movable push rod (304) slides in the inner cavity of the installation tube (305), the reset spring (306) is squeezed. Later, the reset spring (306) after squeezing drives the movable push rod (304) and the cleaning tube (302) to reset. When the cleaning tube (302) and the cleaning tube (302) are When the cleaning sleeve (301) moves to the inside of the charging hole, the brush strip at the end of the cleaning sleeve (301) wraps around the outside of the plug pin, and the single-phase motor (307) is started to drive the rotating rod (310) to rotate, and the transmission rotating wheel (309) is driven to rotate through the rotating rod (310). Since a rotating belt (311) is installed between the transmission rotating wheel (309) and the outside of the rotating small wheel (312), the rotating small wheel (312) is driven to rotate. When the rotating small wheel (312) rotates, it drives the installation cylinder (305) to rotate, which drives the movable top rod (304), the installation ring block (604), the cleaning tube (302) and the cleaning sleeve (301) to rotate, and drives the cleaning sleeve (301) to rotate inside the charging hole for cleaning, and the cleaning sleeve (301) located inside the charging hole does not contact the side of the charging end for cleaning; Step 2: When the rotating rod (310) rotates, the transmission wheel (402) is driven to rotate. Since the transmission belt (404) is installed between the transmission wheel (402) and the rotating disk (405), the rotating disk (405) is driven to rotate.

When the pushing cone block (406) rotates, it contacts the inclined surface of the moving inclined block (407), and the moving inclined block (407) is pushed to move downward. The moving inclined block (407) drives the mounting plate (408) to move downward, and drives the rotating block (411) to move downward, thereby squeezing the airbag (40 3) extruding, and conveying air to the inside of the cleaning tube (302) through the connecting hose (401) and the air hole, and finally spraying the air out through the circular air hole and spraying it into the charging hole, and blowing the dust inside the charging hole and the cleaned dirt to the outside of the charging hole, when the rotating disk (405) rotates, the turbofan head (503) is driven to rotate, and an airflow is formed in the inner cavity of the guide frame head (504), and the airflow is conveyed to the inside of the annular cavity (501) through the connecting air pipe (502), and the air inside the annular cavity (501) is ejected through the air jet hole, and the ejected air cleans the outside of the charging gun; Step 3: When the cleaning tube (302) and the cleaning sleeve (301) rotate for cleaning, if there is adhesive dirt inside the charging hole or on the end surface of the charging gun, the friction force applied to the cleaning sleeve (301) and the cleaning tube (302) when they rotate is too large, which will cause the cleaning tube (302) to twist and drive the push piece (603) to move inside the movable recess (602). When the push piece (603) moves inside the movable recess (602), it squeezes the fixed spring (606). Later, the squeezed fixed spring (606) drives the push piece (603) and the cleaning tube (302) to reset. When the resistance applied to the cleaning tube (302) and the cleaning sleeve (301) is too large, the push piece (603) will contact the pressure controller (605) and activate the alarm inside the control panel, through the alarm with the corresponding number.
