Tunnel lamp cleaning mechanism

Abstract

The invention discloses a tunnel lamp cleaning mechanism. The tunnel lamp cleaning mechanism comprises an outer cover which has a top opening and is used for covering a tunnel lamp overhead, a dry-type cleaning assembly mounted in the outer cover and used for cleaning the surface of the tunnel lamp and a negative pressure forming device which communicates with an inner cavity of the outer cover, wherein a negative pressure hole is formed in the side wall of the outer cover and connected with the negative pressure forming device so that a negative pressure environment is formed in the inner cavity of the outer cover. The cleaning mechanism adopts a dry-type cleaning manner, can recover solid particles falling off during cleaning under negative pressure, is high in cleaning efficiency and causes no pollution to tunnel environment, additionally, labor intensity is reduced, and potential safety hazards caused to workers during climbing are avoided.

Description

technical field [0001] The invention belongs to the technical field of lamp cleaning and relates to a tunnel lamp cleaning mechanism. Background technique [0002] Tunnel lighting is to solve the "black hole effect" or "white hole effect" caused by the sudden change of brightness when the vehicle enters or exits the tunnel. It is a special lamp used for tunnel lighting. The tunnel space is relatively sealed, so the exhaust gas and dust in the tunnel The content is high, and solid particles are easy to accumulate on the surface of the lampshade of the tunnel lamp, which affects the light transmittance of the lampshade, and then affects the lighting effect, resulting in insufficient light in the tunnel and affecting safe passage. Therefore, the lampshade of the tunnel lamp needs to be cleaned; [0003] At present, there are two main cleaning methods commonly used, namely wet cleaning and non-contact dry cleaning; among them, wet cleaning is manual use of elevators to ascend th...

[0002] Tunnel lighting is to solve the "black hole effect" or "white hole effect" caused by the sudden change of brightness when the vehicle enters or exits the tunnel. It is a special lamp used for tunnel lighting. The tunnel space is relatively sealed, so the exhaust gas and dust in the tunnel The content is high, and solid particles are easy to accumulate on the surface of the lampshade of the tunnel lamp, which affects the light transmittance of the lampshade, and then affects the lighting effect, resulting in insufficient light in the tunnel and affecting safe passage. Therefore, the lampshade of the tunnel lamp needs to be cleaned;

[0003] At present, there are two main cleaning methods commonly used, namely wet cleaning and non-contact dry cleaning; among them, wet cleaning is manual use of elevators to ascend the heights, rinse with high-pressure water guns, and use long-handled brushes for scrubbing. The scrubbing efficiency of this method is less than , In addition, sewage drips randomly and pollutes the tunnel environment. In the prior art, large-scale mechanical brushes are also used to scrub with high-pressure water. This method will also cause sewage to pollute the tunnel environment, and the wet cleaning method is likely to cause faults such as short circuit of tunnel lamps; Non-contact dry cleaning mainly uses high-pressure air knives to impact the surface of tunnel lamps through high-pressure air flow. This structure of air knives has a greater impact on the surface of tunnel lamps and is easy to damage tunnel lamps. In addition, there are many solid particles in the car exhaust in the tunnel. The adhesion of solid particles to the tunnel lamps is relatively high. The air knife cleaning method is difficult to effectively clean the solid particles, and the cleaning effect is not good. Moreover, the cleaned solid particles are easily diffused into the tunnel environment by the wind flow, which is harmful to the tunnel environment. The environment causes secondary pollution
