Description

The present invention belongs to the field of lamp cleaning technology, and particularly relates to a smart tunnel lamp cleaning vehicle.

Tunnel lighting fixtures are special lighting fixtures used for tunnel lighting to solve the visual "black hole effect" or "white hole effect" caused by sudden changes in brightness when a vehicle enters or exits a tunnel. Since the tunnel space is relatively sealed, the content of exhaust gas and dust in the tunnel is high, and solid particles are likely to accumulate on the surface of the lampshade in the tunnel, which affects the light transmission of the lampshade. In addition, the lampshades in the tunnel need to be cleaned as they affect the lighting effect, lack the brightness in the tunnel and affect safe passage.

Currently, there are mainly two types of cleaning methods that are often used, wet cleaning and non-contact dry cleaning, respectively. Wet cleaning uses a lifter to artificially perform high-place work, high-pressure water gun cleaning, and brushing with a long-handled brush, resulting in low brushing efficiency and free drop of sewage. The tunnel environment may be polluted, and even with the conventional technology, by brushing with high-pressure water using a large mechanical brush, sewage also pollutes the tunnel environment, and the wet cleaning method is a short circuit of tunnel lighting equipment. Is prone to failure. In non-contact dry cleaning, an air knife with a structure that mainly uses a high-pressure air knife to impact the surface of the tunnel lamp with a high-pressure air stream has a large impact force on the surface of the tunnel lamp, which easily damages the tunnel lamp and is in the tunnel. Since there are many solid particles in the exhaust gas of automobiles and the adhesion of these solid particles to tunnel lamps is large, it is difficult to efficiently clean these solid particles with this air knife cleaning method, and the cleaning effect is inferior. When the solid particles are exposed to the airflow, they easily diffuse into the tunnel environment and secondarily pollute the tunnel environment.

Therefore, there is a need for a tunnel lighting cleaning vehicle that sequentially cleans the tunnel lighting while the in-vehicle platform is running. This cleaning method is contact-dry cleaning, which has a high cleaning effect and collects the cleaned solid particles by negative pressure airflow. High cleaning efficiency, does not pollute the tunnel environment, reduces artificial labor, and avoids safety concerns due to artificial height work.

In view of this, an object of the present invention is to provide a smart tunnel lamp cleaning vehicle. This tunnel lighting equipment cleaning device can sequentially clean the tunnel lighting equipment while the in-vehicle platform is running, and this cleaning method is contact-dry cleaning, which has a high cleaning effect and collects the cleaned solid particles by negative pressure airflow. , High cleaning efficiency, does not pollute the tunnel environment, reduces artificial labor, and avoids safety concerns due to artificial height work.

Brushes and short brushes, long brush rows and short brush rows are arranged alternately in the circumferential direction, and are classified into flat glass type lamps and LED lamp valve type lamps according to the flatness of the surface of the tunnel lamp. When the tunnel lamp is an LED lamp valve system, the surface of the lamp has irregularities, and by adapting a short and long brush to the uneven surface, the cleaning cover surface for the lamp is improved and the cleaning efficiency is improved. Can be done.

In the present embodiment, the outer contour of the sponge roller 34 is formed in a wavy shape extending in the circumferential direction.

As shown in FIG. 9, the outer circumference of the sponge roller 34 also has a wavy concave-convex structure, and due to the elastic deformation ability of the sponge, the protrusion structure on the outer circumference of the sponge roller protrudes into the recess on the surface of the tunnel lamp to facilitate cleaning. Similarly, it can be adapted to a tunnel lamp having irregularities on the surface, facilitating cleaning of the concave portion of the tunnel lamp, and enhancing the cleaning effect.

In the present embodiment, the mounting frame 37 to which the cleaning assembly and the sponge roller 34 are mounted is detachably mounted inside the housing 31.

As shown in FIG. 7, the mounting frame has a frame structure, the outer contour of the mounting frame is fitted into the internal cavity of the housing, the mounting plate 38 is fixedly connected to the mounting frame, and the cylinder is fixed to the mounting plate. The mounting plate facilitates assembly with the cleaning assembly and sponge roller 34, the cleaning assembly and sponge roller 34 and mounting frame can be assembled separately, and can be integrally assembled to the housing with the cleaning assembly. When assembling the sponge roller 34 and the mounting frame, the assembly is facilitated without being limited to the internal space of the housing.

Finally, the above embodiments are for explaining the technical solution of the present invention, and the present invention has been described in detail with reference to preferred embodiments without limitation. For example, the technical solution of the present invention can be modified or replaced with an equivalent one, and the technical solution of the present invention can be used without departing from the spirit and scope of the technical solution of the present invention. It should be understood that it is included in the scope of claims for utility model registration.
