Description

Technical Field

[0001] The present invention relates to the technical field of drainage systems, in particular to a ground combined rapid drainage system for underground garage entrances. Background Art

[0002] In the process of community construction, the drainage system is an important component. The underground garage of the community is a gathering place for water flow due to its low location. When the amount of rainwater is large, rainwater can easily flow back into the garage from the exit, causing property losses to residents. It is an important part of the drainage system. In addition, the current garage drainage generally sets up a ditch at the entrance of the garage to intercept and accumulate water flow on the ground, and then cooperates with a water pump to drain the water from the garage ditch to prevent the water from overflowing and flowing into the underground garage. However, when the amount of water is large, there may be water accumulation in the ditch and around the garage. Due to the infiltration of water, the power equipment may also be paralyzed, causing the ditch to be overwhelmed and overflowing, thereby causing the garage to be flooded. This drainage system has certain disadvantages. At the same time, when the precipitation is large, there are many debris in the water flow, which can easily clog the drainage system, resulting in the water flow not being discharged in time. Summary of the Invention

[0003] The present invention provides a ground combined rapid drainage system for underground garage entrances, which solves the problems of poor drainage effect and potential safety hazards of current garage drainage systems.

[0004] The technical solution of the present invention is achieved as follows:

[0005] A ground combined rapid drainage system for an underground garage entrance comprises a drainage ditch provided in front of the garage door, the drainage ditch being used to intercept water in front of the garage, a bottom plate being provided at the lower end of the drainage ditch, a vegetation layer, a soil layer, a filter layer, a drainage layer and a drainage channel being provided on the bottom plate in order from top to bottom, a jet pump being provided in the drainage layer, a water collecting trough being provided at the upper end of the garage door, the water collecting trough being used to collect water above the garage, water guide buckets being provided on both sides of the garage door, a runner being provided for rotation in the water guide bucket, the water collecting trough being connected to the side of the water guide bucket through a guide pipe, the lower end of the water guide bucket being connected to the nozzle of the jet pump through a reducer, the vortex formed by the runner cooperating with the reducer increasing the impact force of the water flow, and being used to drive the jet pump to work, the water suction pipe of the jet pump being connected to the drainage ditch, and the diffusion pipe of the jet pump being connected to the drainage channel.

[0006] The vegetation layer, soil layer, filter layer, drainage layer and drainage channel are symmetrically arranged on both sides of the garage door.

[0007] Among them, the bottom of the intercepting ditch is curved, and the first water holes are provided on both sides to communicate with the drainage layer. The bottom surface of the drainage layer is inclined, and the higher end is connected to the intercepting ditch. Several groups of special-shaped guide blocks are provided in the drainage layer, and a drainage channel is provided between two adjacent groups of guide blocks. An inlet pipe is provided on the water inlet side of the drainage channel, and an arc-shaped bent plate is provided at the bottom of the drainage channel. The two ends of the drainage channel and the drainage ditch are connected with the embedded water tank through a connecting pipe. The special-shaped guide blocks can not only divert the water, but also intercept some impurities in the water to avoid blockage. The ground of the drainage layer is inclined to prevent excessive water from the drainage layer from flowing back into the intercepting ditch. The embedded water tank connected to the drainage channel can further increase the water capacity of the garage drainage system.

[0008] Among them, the water outlet of the guide pipe is arranged opposite to the blade side of the impeller. The impact force generated by the water drop drives the impeller to rotate, causing the water in the water guide bucket to form a vortex. Combined with the reducer, the impact force of the water flow entering the jet pump is increased, thereby increasing the water absorption capacity of the jet pump.

[0009] Among them, a cover is provided in the water collection tank, which is used to seal the water inlet of the diversion pipe. The upper end of the cover is connected to a suspended ball through a rope, which can automatically open the diversion pipe according to the precipitation, thereby driving the operation of the entire drainage system.

[0010] Wherein, the filter layer is a filter plate, and a plurality of filter holes are provided on the filter plate.

[0011] Beneficial effects

[0012] The present invention connects the water guide hopper with a water collecting trough, and then connects the water guide hopper, intercepting ditch and drainage channel through a jet pump, without the need to set up extra intercepting ditch, motor and other power facilities, with high safety and good reliability. Negative pressure is formed in the intercepting ditch by the jet pump, which can absorb a large amount of water that overflows the intercepting ditch, realize negative pressure water absorption and high-pressure drainage, stabilize the water level in the intercepting ditch, and can automatically adjust the suction force to discharge excess water according to the amount of precipitation. In addition, a double channel is provided for discharging the water in the intercepting ditch, which further reduces the water level in the intercepting ditch and avoids overflow. The present invention is easy to use, low in cost, not easy to damage, and has little safety hazard, avoids the garage from being flooded, and protects the property safety of the people. The vegetation layer, earth city, filtering layer, drainage layer and drainage channel are provided, which increases the water capacity around the garage, avoids the water level around the garage from being too high, reduces the working intensity of the intercepting ditch, facilitates the intercepting ditch to absorb and drain water, and simultaneously performs multiple filtration and diversion on the water flow, avoiding the problem of drainage system blockage.

The water in the water collection trough 6 enters the water collection bucket 7 through the diversion pipe 2, and the impact force of the water in the diversion pipe 2 drives the rotation 8 to rotate, so that the water in the water collection bucket 7 forms a vortex, increases the flow rate, and then the water in the water collection bucket 7 After being accelerated and pressurized in the second layer of the reducing pipe 9, the water enters the jet pump 19, and the jet pump 19 starts to form a negative pressure in the intercepting ditch 20, sucking out the water in the intercepting ditch 20 and the water overflowing the intercepting ditch 20, and then discharged at high pressure through the jet pump 19, discharged into the drain ditch 17, and discharged from the drain ditch 17. The water in the intercepting ditch 20 is automatically discharged through the dual discharge channel according to the amount of precipitation, further stabilizing the water in the intercepting ditch 20. In addition, part of the drainage system of this device is controlled and driven by precipitation, with low cost.
