Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, specifically a cleaning device for highway electromechanical equipment. Background Technology

[0002] Electromechanical equipment generally refers to mechanical, electrical, and electrical automation equipment. In construction, it often refers to a general term for mechanical and piping equipment excluding earthwork, carpentry, steel reinforcement, and masonry work. It differs from hardware, which generally refers to finished products that perform specific functions. Highways also utilize a large number of electromechanical equipment, which plays a crucial role in toll collection, communication, and monitoring systems. This includes industrial control computers in toll booths, monitors, toll keyboards, multi-function readers, lane printers, toll display screens, barrier gates, workstations, switches, routers, printers, data storage devices, emergency telephone systems, and automatic fire alarm systems. To ensure the normal operation of this equipment, cabinet-type devices such as switches and routers typically require cleaning. However, when dealing with a large number of machines, traditional methods using hand-held cloths for cleaning can easily lead to fatigue, reduced work efficiency, and decreased cleanliness, potentially affecting the normal operation of the equipment. Therefore, a highway electromechanical equipment cleaning device is needed to address these issues. Summary of the Invention

[0003] The purpose of this invention is to provide a cleaning device and method for highway electromechanical equipment to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A cleaning device for highway electromechanical equipment includes a housing, a piston cylinder disposed inside the housing, and the piston cylinder being connected to a liquid storage tank fixedly installed inside the housing via a suction pipe.

[0006] A cleaning mechanism is disposed within the housing and includes a reciprocating assembly and a rotating wiping assembly. The reciprocating assembly includes a sliding member slidably disposed on the housing, and a cleaning roller is rotatably mounted on the sliding member. The cleaning roller is connected to the rotating wiping assembly. When the reciprocating assembly drives the sliding member to move up and down in the vertical direction of the space of the housing, the rotating wiping assembly can move and drive the cleaning roller to rotate relative to the sliding member.

[0007] The wetting assembly, disposed within the housing, includes a spraying structure and a pumping structure. The spraying structure is connected to the piston cylinder and the cleaning roller, and the pumping structure is connected to the sliding member. When the sliding member moves up and down vertically along the space of the housing, the pumping structure can spray the cleaning agent in the piston cylinder onto the cleaning roller.

[0008] As a further aspect of the present invention: the sliding member includes a sliding plate, and a snap-fit ​​rod is fixedly disposed on the side of the sliding plate facing the outer shell. The snap-fit ​​rod is slidably disposed in a snap-fit ​​groove opened on the outer shell, and a sliding groove is provided on the sliding plate.

[0009] As a further embodiment of the present invention: the reciprocating assembly further includes pulleys rotatably mounted on the housing, and two sets of pulleys are arranged along the length direction of the housing. One set of pulleys is fixedly connected to the output shaft of a motor fixedly mounted inside the housing, and belts are mounted on both sets of pulleys. Protrusions are fixedly provided on the belts, and the protrusions are slidably disposed in the grooves.

[0010] As a further embodiment of the present invention: the rotary wiping assembly includes a gear coaxially and fixedly connected to the cleaning roller, the gear meshing with a rack plate fixedly mounted on the housing.

[0011] As a further embodiment of the present invention: the spraying structure includes a spray head rotatably installed inside the cleaning roller, the spray head having a series of spray holes equidistantly spaced along its circumference, and the end of the spray head away from the gear being connected to the piston cylinder through a spray pipe.

[0012] As a further embodiment of the present invention: the pumping structure includes a connecting rod fixedly connected to the sliding plate, and a sliding sleeve is fixedly provided at one end of the connecting rod away from the sliding plate. The sliding sleeve is connected to a piston rod slidably disposed on the piston cylinder, and a baffle rod is formed inside the sliding sleeve. The baffle rod is slidably disposed in a through groove opened on the piston rod.

[0013] As a further aspect of the present invention, a method for cleaning highway electromechanical equipment is also proposed, employing the aforementioned highway electromechanical equipment cleaning device, comprising the following steps:

[0014] Step 1: Start the motor. The motor drives the pulley to rotate continuously in the same direction, driving the belt into the transmission state. At this time, the protrusion fixed on the belt drives the sliding plate to slide and rise along the locking groove.

[0015] Step 2: As the belt continues to rotate and the cleaning roller rises with the sliding plate, the gear and rack engage in a transmission state, which drives the cleaning roller to rotate relative to the sliding plate to wipe the side wall of the electromechanical equipment.

[0016] Step 3: The sliding sleeve rises with the sliding plate and slides relative to the piston rod until the partition rod moves to the end of the stroke leading to the groove. The sliding sleeve drives the piston rod to move towards the inside of the piston cylinder, pumping the cleaning agent in the piston cylinder to the cleaning roller and wetting the cleaning roller.

[0017] Step 4: The belt continues to rotate, driving the cleaning roller to descend. At this time, the sliding sleeve first slides relative to the piston rod, and then drives the piston rod to descend along its axial direction, pumping the cleaning agent in the storage tank into the piston cylinder.

[0018] Step 5: Repeat steps 2, 3, and 4 above. The cleaning roller can perform reciprocating wiping motions along the vertical direction of the outer shell space, thereby achieving the cleaning of the side walls of the electromechanical equipment.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] By setting up a cleaning mechanism and utilizing the cooperation between the reciprocating component and the rotating wiping component, when in use, the outer casing is placed on the side of the mechanical equipment to be cleaned, so that the cleaning roller abuts against the side of the mechanical equipment. After starting the motor, the protrusion fixed on the belt drives the sliding plate to perform a reciprocating lifting motion. During the reciprocating lifting motion of the sliding plate, the rotating wiping component moves, which can drive the cleaning roller to rotate. At this time, the cleaning roller reciprocates and rotates along the side of the mechanical equipment, which can clean the surface of the mechanical equipment.

[0021] By setting up a wetting component and utilizing the cooperation between the spraying structure and the pumping structure, the cleaning agent stored in the piston cylinder and the liquid tank can be pumped to the cleaning roller, so that the cleaning roller during the lifting operation is covered with a sufficient amount of cleaning agent. The cleaning work is carried out by using the wet cleaning roller, which can improve the cleanliness of the outside of the electromechanical equipment. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and 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.

[0031] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0032] Please see Figures 1-7 In this embodiment of the invention, a cleaning device for highway electromechanical equipment includes a housing 1, a piston cylinder 9 is provided inside the housing 1, and the piston cylinder 9 is connected to a liquid storage tank 10 fixedly installed inside the housing 1 through a suction pipe 21.

[0033] For details, please refer to Figure 2 , Figure 7 The piston cylinder 9 and the liquid storage tank 10 are fixedly installed on the upper end of the outer shell 1. Both contain cleaning agents. An inlet is fixedly installed on the upper surface of the liquid storage tank 10. A detachable bottle cap (not shown in the figure) is installed on the inlet. When the cleaning agent in the liquid storage tank 10 is used up, the bottle cap can be unscrewed to replenish the cleaning agent in the liquid storage tank 10 for subsequent cleaning of the electromechanical equipment. It should be noted that the connection end of the suction pipe 21 to the liquid storage tank 10 is inserted into the bottom of the liquid storage tank 10, and a one-way valve is provided at the connection end of the suction pipe 21 to the piston cylinder 9 so that the cleaning agent in the liquid storage tank 10 can only enter the suction pipe 21 and flow into the piston cylinder 9.

[0034] The cleaning mechanism is disposed inside the housing 1 and includes a reciprocating component and a rotating wiping component. The reciprocating component includes a sliding member slidably disposed on the housing 1. A cleaning roller 5 is rotatably mounted on the sliding member. The cleaning roller 5 is connected to the rotating wiping component. When the reciprocating component drives the sliding member to move up and down in the vertical direction of the space of the housing 1, the rotating wiping component can move and drive the cleaning roller 5 to rotate relative to the sliding member.

[0035] The sliding component includes a sliding plate 15, and a snap-fit ​​rod 20 is fixedly provided on the side of the sliding plate 15 facing the outer shell 1. The snap-fit ​​rod 20 is slidably disposed in a snap-fit ​​groove 22 opened on the outer shell 1, and a sliding groove 23 is provided on the sliding plate 15.

[0036] For details, please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 Two sets of connecting rings are fixedly installed on the sliding plate 15. The cleaning roller 5 is rotatably installed in the connecting rings so that the cleaning roller 5 can rotate relative to the sliding plate 15. The cleaning roller 5 is provided with a series of through holes at equal intervals along its circumference. In particular, the outer side of the cleaning roller 5 is wrapped with a layer of cotton or sponge cleaning cloth. When in use, the outer shell 1 is placed on one side of the electromechanical equipment to be cleaned so that the surface of the cleaning roller 5 is in contact with the side wall of the electromechanical equipment. When the sliding plate 15 moves up and down in the vertical direction of the space of the outer shell 1, the cleaning roller 5 can wipe the side wall of the electromechanical equipment back and forth.

[0037] The reciprocating assembly also includes pulleys 8 rotatably mounted on the housing 1. Two sets of pulleys 8 are arranged along the length of the housing 1. One set of pulleys 8 is fixedly connected to the output shaft of a motor fixedly mounted inside the housing 1. Belts 6 are mounted on both sets of pulleys 8. Protrusions 16 are fixedly provided on the belts 6. The protrusions 16 are slidably disposed in the groove 23.

[0038] For details, please refer to Figure 1 , Figure 4 The aforementioned protrusion 16 is slidably disposed in the groove 23 opened on the sliding plate 15. After the motor is started, the output shaft of the motor drives the pulley 8 to rotate continuously in the same direction. At this time, the protrusion 16 fixed on the belt 6 moves with the belt 6, which can drive the sliding plate 15 to reciprocate along the locking groove 22, thereby completing the surface cleaning work of the electromechanical equipment.

[0039] The rotary wiping assembly includes a gear 4 that is coaxially and fixedly connected to the cleaning roller 5, and the gear 4 meshes with a rack plate 3 that is fixedly mounted on the housing 1;

[0040] For details, please refer to Figure 1 , Figure 3 The gear 4 and the cleaning roller 5 are coaxially fixedly connected. As can be seen from the above, when the motor drives the sliding plate 15 to rise vertically along the outer shell 1, the gear 4 and the rack plate 3 fixedly connected to the cleaning roller 5 enter the meshing transmission state, which can drive the gear 4 to rotate. When the sliding plate 15 descends vertically along the outer shell 1, the gear 4 and the rack plate 3 mesh and reverse. By using the forward and reverse rotation of the cleaning roller 5, the outer surface of the electromechanical equipment can be cleaned.

[0041] The electromechanical system of highways is divided into toll collection system, communication system, and monitoring system. Among them, the electromechanical equipment plays a crucial role, including cabinet-type mechanical equipment such as switches and routers. In daily life, in order to ensure the normal operation of the electromechanical equipment, it is usually necessary to clean cabinet-type equipment such as switches and routers. However, when facing a large number of mechanical equipment, the traditional method of cleaning with a hand cloth can easily lead to fatigue, reduce work efficiency, and reduce the cleanliness of the mechanical equipment. In this embodiment of the invention, by setting up a cleaning mechanism, the cooperation between the reciprocating component and the rotating wiping component is used. When in use, the outer shell 1 is placed on the side of the mechanical equipment to be cleaned, so that the cleaning roller 5 abuts against the side of the electromechanical equipment. After the motor is started, the protrusion 16 fixed on the belt 6 drives the sliding plate 15 to perform a reciprocating lifting and lowering action. During the reciprocating lifting and lowering of the sliding plate 15, the rotating wiping component moves, which can drive the cleaning roller 5 to rotate. At this time, the cleaning roller 5 is reciprocated and rotated along the side of the electromechanical equipment, which can clean the surface of the electromechanical equipment.

[0042] As one embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 A cleaning device for highway electromechanical equipment, further comprising a wetting component disposed within the housing 1, including a spraying structure and a pumping structure. The spraying structure is connected to the piston cylinder 9 and the cleaning roller 5, and the pumping structure is connected to the sliding member. When the sliding member moves up and down vertically along the space of the housing 1, the pumping structure can spray the cleaning agent in the piston cylinder 9 onto the cleaning roller 5.

[0043] The spraying structure includes a spray head 17 rotatably installed inside the cleaning roller 5. The spray head 17 has a series of spray holes equidistantly arranged along its circumference, and the end of the spray head 17 away from the gear 4 is connected to the piston cylinder 9 through the spray pipe 2.

[0044] For details, please refer to Figure 1 , Figure 3 , Figure 5The spray head 17 is rotatably installed inside the cleaning roller 5. In particular, a one-way valve is provided at the connection end between the spray pipe 2 and the piston cylinder 9 so that the cleaning agent in the piston cylinder 9 can only flow to the spray head 17 through the piston cylinder 9. When the spray pipe 2 delivers the cleaning agent to the spray head 17, the spray head 17 will spray the cleaning agent evenly onto the cleaning roller 5, wetting the cleaning roller 5. At this time, the wet cleaning roller 5 can improve the cleanliness of the outside of the electromechanical equipment.

[0045] The pumping structure includes a connecting rod 13 fixedly connected to the sliding plate 15. A sliding sleeve 11 is fixedly provided at one end of the connecting rod 13 away from the sliding plate 15. The sliding sleeve 11 is connected to the piston rod 12 slidably disposed on the piston cylinder 9. A baffle rod 14 is formed inside the sliding sleeve 11. The baffle rod 14 is slidably disposed in the through groove 18 opened on the piston rod 12.

[0046] For details, please refer to Figure 2 , Figure 6 , Figure 7 The connecting rod 13 penetrates the outer casing 1 and is placed in the through groove 7 opened on the outer casing 1. Specifically, a piston disc 19 is fixedly installed at one end of the piston rod 12 that is inserted into the piston cylinder 9. In the initial state, the piston disc 19 is in contact with the lower bottom surface of the piston cylinder 9. At this time, the protrusion 16 is located at the lowest point of the belt 6, the sliding plate 15 is located at the end of the snap-fit ​​groove 22, and the baffle rod 14 abuts against the end of the through groove 18. After the motor is started, the sliding plate 15 rises in the vertical direction of the outer casing 1. At this time, the sliding sleeve 11 slides along the through groove 18 until the baffle rod 14 moves to the end of the through groove 18, and the sliding plate 15... As the piston rod rises, the sliding sleeve 11 drives the piston rod 12 to move towards the inside of the piston cylinder 9, pumping the cleaning agent in the piston cylinder 9 to the spray head 17, thereby wetting the cleaning roller 5. When the sliding plate 15 moves and engages the end of the groove 22, the cleaning agent in the piston cylinder 9 is just completely pumped to the spray head 17. Then the sliding plate 15 descends, and the sliding sleeve 11 descends radially along the piston rod 12 until the baffle rod 14 returns to its initial position. The piston rod 12 then descends with the sliding sleeve 11, which can draw the cleaning agent in the storage tank 10 into the piston cylinder 9, preparing for the subsequent wetting of the cleaning roller 5.

[0047] In this embodiment of the invention, by setting up a wetting component and utilizing the cooperation between the spraying structure and the pumping structure, the cleaning agent stored in the piston cylinder 9 and the liquid storage tank 10 can be pumped to the cleaning roller 5, so that the cleaning roller 5 in the lifting operation is saturated with a sufficient amount of cleaning agent. By using the wet cleaning roller 5 to perform the cleaning work, the cleanliness of the outside of the electromechanical equipment can be improved.

[0048] As an embodiment of the present invention, a method for cleaning highway electromechanical equipment is also proposed, which uses the aforementioned highway electromechanical equipment cleaning device and includes the following steps:

[0049] Step 1: Start the motor. The motor drives the pulley 8 to rotate continuously in the same direction, driving the belt 6 into the transmission state. At this time, the protrusion 16 fixed on the belt 6 drives the sliding plate 15 to slide and rise along the locking groove 22.

[0050] Step 2: As the belt 6 continues to rotate and the cleaning roller 5 rises with the sliding plate 15, the gear 4 and the rack plate 3 enter a meshing transmission state, which can drive the cleaning roller 5 to rotate relative to the sliding plate 15 to wipe the side wall of the electromechanical equipment.

[0051] Step 3: The sliding sleeve 11 rises with the sliding plate 15 and slides relative to the piston rod 12 until the partition rod 14 moves to the end of the stroke leading to the groove 18. The sliding sleeve 11 drives the piston rod 12 to move towards the inside of the piston cylinder 9, pumping the cleaning agent in the piston cylinder 9 to the cleaning roller 5, and wetting the cleaning roller 5.

[0052] Step 4: The belt 6 continues to rotate, driving the cleaning roller 5 to descend. At this time, the sliding sleeve 11 first slides relative to the piston rod 12, and then drives the piston rod 12 to descend along its axial direction, pumping the cleaning agent in the storage tank 10 into the piston cylinder 9.

[0053] Step 5: Repeat steps 2, 3, and 4 above. The cleaning roller 5 can perform a reciprocating wiping action along the vertical direction of the outer shell 1, thereby achieving the cleaning of the side wall of the electromechanical equipment.
