Description

Ventilation, lighting and water collection integrated device for underground garage

technical field

The invention relates to an integrated ventilation, daylighting, daylighting and water collection device for underground garages, and is especially suitable for underground garages.

Background technique

Underground parking lots, underground shopping malls, subway stations and other underground places are closely related to people's daily life, and have good prospects for improving the development and utilization of underground space. At present, the energy consumption of underground garages is provided by the ground, including electric energy, water resources, etc. Ventilation in underground garages has always been an important issue, and conventional ventilation devices such as fans are usually used for underground garage ventilation. Additional electrical energy loss is generated, and this ventilation method relies on electrical energy and cannot work properly when there is a power outage. Some underground spaces use ventilation pipes to connect to the ground and use natural wind for ventilation, but because there is no power source, the ventilation efficiency is often very low and the expected effect cannot be achieved.

The existing underground garages cannot collect rainwater for utilization, which wastes a lot of resources virtually, and the water resources needed for the underground space need groundwater, and even the reclaimed water in the underground garage needs groundwater, which speeds up the utilization of groundwater, and rainwater is A substitute for reclaimed water in life; the underground space is dark 24 hours a day, so in order to maintain a good lighting effect, traditional lighting is used for lighting in the underground space, which consumes electricity and does not conform to the design concept of green buildings.

The reflector inside the light guide guides the sunlight to the bottom of the light guide, and the concave lens at the bottom scatters the sunlight to the interior of the underground garage for lighting. Solar panels are also arranged around the top of the light pipe, which can not only charge the battery but also protect the ventilation pipe from rain. In terms of water collection, the water collection layer is divided into multiple layers of filtration. After the rainwater falls on the ground, it is filtered by the soil layer, coarse sand layer, fine sand layer, coarse filter, medium filter, and fine filter before being filtered by the water collection tank. Collection, on the one hand, forms a cold area and promotes ventilation; on the other hand, the water in the water tank can also be introduced into the underground garage through the aqueduct for utilization. In order to prevent the exhaustion of the water in the water collection tank, resulting in weakening of the ventilation effect, there are independent water tanks on both sides of the ventilation pipe, and a check valve is installed at the connection between the independent water tank and the water collection tank, and the water can flow into the independent water tank through the water collection tank to supplement the water volume. No flow from individual tanks to collection tanks.

detailed description

In order to further illustrate the technical details of the present invention, it is now described in conjunction with the accompanying drawings. As shown in Fig. 1, the present invention comprises water collecting layer 11, ventilation pipe 5 and daylighting device, and described water collecting layer 11 is arranged on the top of underground garage, and described water collecting layer 11 includes being arranged at the bottom of water collecting layer 11 Water collecting tank 19; said water collecting layer 11 is provided with several ventilation pipes 5, and said ventilation pipes 5 run through the water collecting layer 11, and a daylighting device is arranged in the ventilation pipe 5, and said daylighting device comprises a daylighting cover 1 and Light guide pipe 4; said light guide pipe 4 is connected with ventilation pipe 5 through connector 23; the interval between said light guide pipe 4 and ventilation pipe 5 forms air outlet 3, and air outlet 3 is provided with suction Thermal Materials10.

Utilizing the principle that the temperature difference makes the air flow to generate wind, an independent water tank 6 and a water collection tank 19 are arranged at the bottom of the ventilation pipe 5, as shown in Figure 2, the top of the water tank is covered with a soil layer, and due to the large specific heat capacity of water, the top of it is covered with a soil layer , to play the role of heat insulation, so the water temperature in the water tank is relatively stable, obviously lower than the surface temperature, and the part of the ventilation pipe 5 exposed to the ground is wrapped with a black chrome plated heat absorbing material 10, and under the sunlight during the day, this section The temperature of the ventilation pipe 5 rises, forming a temperature difference with the lower shady part, improving the original ventilation efficiency of the ventilation pipe 5 . The interval formed between the light guide pipe 4 and the ventilation pipe 5 accelerates the wind speed, which can bring a comfortable sense of air flow to the interior of the underground garage. In order to prevent the water in the water collection tank 19 from running out, causing the ventilation effect to weaken, independent water tanks 6 are arranged on both sides of the ventilation pipe 5, and a check valve 24 is provided at the connection between the independent water tank 6 and the water collection tank 19, and water can pass through the water collection tank 19. Flow into independent water tank 6 supplementary water yield, can not flow to water collecting tank 19 from independent water tank 6.

If the water in the independent water tank 6 is stored for too long, bacteria and microorganisms will grow and the corrosion of the water tank will be accelerated, so corresponding measures must be taken to enable the water in the independent water tank 6 to be replaced. In this embodiment, the independent water tank 6 and the water collection tank 19 have two communicating pipes, which are respectively arranged at the bottom and the middle of the independent water tank 6. The connecting pipes at the bottom are provided with a check valve 24 to prevent the water in the independent water tank 6 from being fully drained. Drain, the connecting pipe in the middle can communicate with the water collecting tank 19 in two directions, and in the process of repeated water intake and water discharge, the water in the independent water tank 6 has been replaced, which can prolong the life of the water tank.

As shown in Figure 3, described catchment layer 11 is divided into soil layer, coarse gravel layer, fine gravel layer, coarse filter screen 16, middle filter screen 17, fine filter screen 18 and water collection box 19 from top to bottom ; The filter support columns 20 are uniformly distributed below the coarse filter 16 ; The bottom of the water collection tank 19 is provided with a water guide pipe 21, and the top is provided with an overflow pipe 22; the soil layer is planted with vegetation 12. The rainwater is filtered through multiple layers to remove most of the solid impurities in the water, enters the water collection tank 19, and is introduced into the underground garage through the aqueduct 21, and can be used for flushing toilets, washing mops, etc.

Considering that rainwater may flow into the underground garage along the ventilation pipe 5, when installing the solar panel 2, use screws and nuts to fix the solar panel 2 at an angle of 45 degrees to the vertical direction, and the bottom cover of the solar panel 2 Pass the edge of the ventilation pipe 5 to prevent rainwater from directly falling into the ventilation pipe 5. At the same time, vertical boards are arranged around the top of the ventilation pipe 5, and the vertical boards are wrapped with heat-absorbing materials 10, which can absorb heat in sunny days and can be used in rainy days. Prevent ground pond water from flowing into vent pipe 5.
