Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning highway delineators, specifically to a rapid cleaning device for highway delineators. Background Technology
[0002] Highway delineators, as important traffic safety facilities, are typically installed along both sides of the road at 50-meter intervals. Their function is to clearly display the road boundary outline and guide vehicles to drive correctly. Especially on windy and sandy sections such as the Beijing-Xinjiang Expressway (Suhongtu section), delineators also serve as road outline indicators under adverse weather conditions. However, due to the high wind and sand volume and heavy traffic in this area, the surfaces of the roadside delineators easily accumulate oil, dust, and other pollutants, severely affecting their retroreflective properties and service life.
[0003] Currently, the industry commonly uses manual mopping to maintain delineators. This method has many drawbacks: First, it is inefficient, taking 1-2 minutes to clean a single delineator; second, it is physically demanding for operators, and prolonged repetitive work can easily lead to fatigue; third, sometimes excessive force is used during cleaning, causing damage to the delineator surface or breakage of the mop. Furthermore, traditional cleaning tools lack specific design features and cannot be properly matched to the shape of the delineators, further reducing cleaning effectiveness and work efficiency. These problems are particularly prominent in large-scale highway maintenance operations, severely restricting the maintenance efficiency of road safety facilities. Utility Model Content

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:
[0018] like Figure 1 As shown, this application proposes a rapid cleaning device for highway delineators, including a cleaning housing that matches the shape of the delineator, a cleaning liner that can be quickly cleaned and replaced inside the cleaning housing, and an operating lever for pulling up and down on the outside of the cleaning housing.
[0019] The cleaning housing features an arc-shaped structure that conforms to the contour marker's shape, completely enclosing its surface. The cleaning housing can be made of engineering plastic or stainless steel, with a thickness of 2-5mm. The cleaning liner is removable and secured inside the cleaning housing with clips. The operating lever consists of metal rods fixed to both sides of the cleaning housing, with a length of 50-80cm, facilitating operation while standing.
[0020] This device achieves rapid positioning through a cleaning housing that matches the shape of a delineator, while its built-in replaceable cleaning liner effectively removes oil and dirt. The lever design eliminates the need to bend over during cleaning, significantly improving efficiency. Compared to traditional mop cleaning methods, this device avoids the problem of uncontrollable cleaning force and reduces wear and tear on cleaning tools. The replaceable cleaning liner makes maintenance easier and is suitable for use in windy, dusty highway environments.
[0021] like Figure 2 As shown, this application further proposes that the cleaning liner includes a rigid inner core that matches the shape of the cleaning shell, a sponge layer is provided on the outside of the rigid inner core, and a cotton cloth cover is provided on the outside of the rigid inner core and the sponge layer.
[0022] Specifically, the rigid inner core is made of ABS engineering plastic or stainless steel, with its inner surface tightly fitting the inner wall of the cleaning shell, and its outer surface having evenly distributed ventilation holes. The sponge layer is made of polyurethane open-cell foam material, with a thickness of 8-12mm, and is bonded to the inner surface of the rigid inner core with environmentally friendly adhesive. The cotton cover layer adopts a double-layer knitted structure, with the inner layer being highly absorbent pure cotton and the outer layer being a wear-resistant polyester-cotton blend material. As a preferred embodiment, such as... Figure 3 As shown, the rigid inner core can be designed as a three-fold rigid plastic plate that can be bent to facilitate its insertion into the cotton cover layer.
[0023] Therefore, this technical solution employs a three-layer composite structure design. A rigid inner core provides rigid support, ensuring a close fit to the delineator's surface; a sponge layer acts as a buffer, preventing damage to the delineator during cleaning; and a cotton cloth cover enables efficient cleaning while protecting the sponge layer. Compared to existing technologies, this structure significantly reduces the wear rate of cleaning components while maintaining cleaning effectiveness. The replaceable cotton cloth cover further reduces maintenance costs. In practice, the operator simply places the cleaning housing on the delineator and moves it up and down to complete the cleaning operation. The cotton cloth cover effectively absorbs oil and dust, and the elastic deformation of the sponge layer ensures adaptability to delineators of different sizes.
[0024] like Figure 2 As shown, this application further proposes that the bottom of the cleaning housing is provided with a limiting bend to restrict the cleaning liner, and the upper part of the cleaning housing is provided with a limiting screw to restrict the top of the cleaning liner.
[0025] The limiting bend, through its inward bending structure, provides stable support and restraint for the cleaning liner from the bottom. This bend can be manufactured using metal stamping or plastic injection molding processes, with a bending angle preferably between 90 and 120 degrees to ensure sufficient support strength. The limiting screw is fixed to the upper part of the cleaning housing via a threaded connection; the bolt diameter is preferably 6-10 mm to balance strength and ease of operation. The limiting screw can be made of stainless steel to prevent corrosion.
[0026] This technical solution effectively solves the problem of easy displacement of the cleaning liner during use through a double-limiting structure. The limiting bend provides support from the bottom to prevent the cleaning liner from sliding down during cleaning; the limiting screw applies pressure from the top to prevent the cleaning liner from shaking during operation. This achieves a stable fixation of the cleaning liner, ensuring the stability and reliability of the cleaning operation. Compared with existing technologies, this solution has a simple and reliable structure, and the cleaning liner can be installed and fixed without additional tools, significantly improving the efficiency of the cleaning operation.
[0027] like Figure 1 As shown, this application further proposes that the operating lever includes a pull rod fixed to both sides of the cleaning housing and extending upward, with a handle fixed to the top of the pull rod.
[0028] The pull rod is made of metal tubing with a diameter ranging from 10-15mm and a wall thickness of 1-2mm. The pull rod is fixed to the cleaning housing by welding, using continuous fillet welds, and M6 or M8 bolts are used for bolt connections. The handle is made of injection-molded plastic with a non-slip textured surface. The handle is 15-20cm long and 3-5cm in diameter. The handle is also fixed to the pull rod by welding.
[0029] This technical solution, through the design of a pull rod and handle, allows operators to easily grip and apply force, avoiding slippage or uneven force distribution issues that may occur with direct contact with the cleaning housing. The extended design of the pull rod increases the lever arm length, reducing the force required for operation, while the ergonomic design of the handle improves operating comfort. Compared to existing technologies that directly use a mop for cleaning, this structure provides more stable control over cleaning force and direction, preventing damage to the delineator or cleaning tools due to excessive force, while also improving cleaning efficiency. Specifically, through the cooperation of the pull rod and handle, operators can more precisely control the movement trajectory and pressure of the cleaning housing, ensuring consistent cleaning results.
[0030] like Figure 2 As shown, this application further proposes that the limiting screw is threaded to the side of the pull rod and has a locking nut on the outside.
[0031] The limiting screw is fixed to the side of the pull rod via a threaded connection. A lock nut is installed on the outer end of the limiting screw, and the limiting screw is fixed by tightening the lock nut. As a preferred embodiment, the limiting screw can be a standard bolt of M6 or M8 specification, and the lock nut can be a matching anti-loosening nut. Furthermore, a washer can be placed at the connection between the limiting screw and the pull rod to enhance the connection stability.
[0032] This technical solution achieves reliable positioning of the top of the cleaning liner through the use of threaded connections and locking nuts. Therefore, this structure ensures both the stability of the cleaning liner installation and ease of adjustment according to actual needs. Compared with existing technologies, this solution solves the problem of component damage caused by excessive force during manual cleaning, achieving stable and reliable cleaning operations through mechanical positioning.
[0033] like Figure 2 As shown, this application further proposes that the limiting bend is supported at the bottom of the rigid inner core of the clean inner liner, and the outer end of the locking nut is restricted at the top of the rigid inner core.
[0034] The limiting bending part can be formed by stamping metal sheet, with a bending angle of 90°-120°. The locking nut can be a nylon anti-loosening nut or a metal flange nut, with a preferred thread specification of M6-M8. A rubber buffer pad can be provided on its outer end face to prevent excessive compression from deforming the rigid inner core. As a preferred embodiment, an annular flange can be provided at the top of the rigid inner core, and the locking nut achieves axial positioning by pressing the flange.
[0035] The implementation principle of a waterproof cable trench in this application embodiment is as follows:
[0036] During cleaning, the cleaning personnel wet the sponge layer 6 and cotton cloth cover layer 7 of the cleaning liner, and use the handle to pull the cleaning housing 1 over the outline marker 11 via the pull rod 3. Pulling it up and down allows the inner cleaning liner 2 to quickly clean the outline marker 11. When the cleaning liner 2 wears out after a certain period of use or needs cleaning, simply loosen the locking nut 10 and the limit screw 9 to pull the cleaning liner 2 out from the top of the cleaning housing 1 for cleaning, or replace the cotton cloth cover layer 7. After replacement, it can be quickly reinstalled for use, ensuring convenient maintenance. The above shows and describes the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of this utility model as claimed.
