Anti-seepage light transmitting device for underground garage

Abstract

The invention relates to an anti-seepage light transmitting device for an underground garage. The anti-seepage light transmitting device comprises a light reflecting tube and an anti-seepage device. The top end, protruding out of an upper end face on the roof of the garage, of the light reflecting tube is fixedly provided with a light gathering cover, the bottom end, protruding out of a lower end face on the roof of the garage, of the light reflecting tube is provided with a diffuser, the inner wall of the light reflecting tube is provided with a light reflecting film layer, and the anti-seepage device is arranged on the outer side wall of the part, protruding out of the roof of the garage, of the light reflecting tube in a sleeved mode. The anti-seepage light transmitting device further comprises a protection casing pipe arranged on the upper portion of the outer wall of the light reflecting tube in a sleeved mode. The anti-seepage device integrally is a hollow coaxial step-shaped boss, and a gap is reserved between the lower layer boss of the anti-seepage device and the outer side wall of the light reflecting tube to form an anti-leakage cavity. The anti-seepage light transmitting device has the advantages that the protection casing pipe is additionally arranged on the light reflecting tube, the anti-seepage device is changed into the coaxial step-shaped boss, then rainwater cannot enter the garage roof along the outer wall of the light reflecting tube even when being reversely poured into the anti-leakage cavity, the water leakage problem is solved, and the sealing of the diffuser and the garage roof is better through an additionally arranged lower seal ring.

Description

technical field [0001] The invention relates to the technical field of solar light utilization, in particular to an anti-seepage water light transmission device for underground garages. Background technique [0002] Natural light is a precious wealth bestowed by nature to human beings. It can be said to be inexhaustible. Compared with other energy sources, it is clean and safe. Making full use of natural light can save a lot of electricity for lighting, and saving electricity can indirectly Reduce the consumption of natural resources and the emission of harmful gases. In January 1991, the U.S. Environmental Protection Agency (EPA) first proposed the concept of implementing "Green Lights" and promoting the "Green Lights Program". On November 16, 1995, eight units were held to discuss the "China Green Lighting Implementation Plan", one of which was to promote natural lighting. Therefore, natural lighting is an important direction of green lighting. With the improvement of th...

Problems solved by technology

Therefore, natural lighting is an important direction of green lighting. With the improvement of the living standards of Chinese residents, the number of cars is increasing, and the construction of underground garages is also increasing. The underground garage is the most suitable place to use this technology. Chinese patent ZL200720102858.4 provides a sunlight importing device, but this device has two significant disadvantages: 1. The seal between the diffuser and the roof of the garage is not good; 2. It is easy to leak

This has just caused the various inconveniences in popularizing and using of this device, therefore be badly in need of a kind of improved device to overcome above-mentioned shortcoming
