Description
Technical Field
The invention relates to a subway wind power regulation and control system, in particular to a system which is provided with a tunnel shield door in a subway tunnel and is used for regulating and controlling and reasonably utilizing subway piston wind, and belongs to the technical field of subway station system design.
background
due to the characteristics of the subway system, the piston effect and the piston wind are generated in the process of entering or leaving the subway train, and the subway environmental control system is greatly influenced.
The prior art and research show that the energy consumption of the subway environment control system can be reduced by reasonably utilizing piston wind, and the subway environment control system is adversely affected if the piston wind is not properly processed.
the subway station comprises a platform/station hall area, a subway tunnel and a station rail-walking area, wherein in order to prevent the adverse effect of piston wind on an environment control system of the platform/station hall area in the existing system, a platform shielding door is adopted to separate the platform area and the station rail-walking area into relatively independent space areas.
however, the utilization methods of the piston wind are greatly different according to different cities, different seasons and different real-time climatic conditions, and a technical scheme for comprehensively utilizing the piston wind does not exist in the prior art. If the piston wind is to be reasonably utilized, the following problems need to be solved:
1. when piston wind is generated, partial air flow is divided by the subway tunnel, so that the available effective piston wind quantity is reduced;
2. When the subway piston wind is used for ventilation, the directions of the piston wind generated when a subway train enters a station and leaves the station are opposite, and the ventilation effects can be mutually counteracted if the piston wind is not controlled;
3. When the subway wind power is used for wind power generation, only a small part of wind power can be utilized at any fixed position, so that a scattered collection mode is adopted, the use efficiency of power generation equipment is low, and the initial investment is high;
4. under different working conditions, the usage and the usage amount of the piston wind are different, so that reasonable guiding and adjusting means are needed.

disclosure of Invention
in order to solve the technical problems, the invention adopts the technical scheme of arranging the tunnel shielding door in the subway tunnel, enhances the wind strength of the subway piston, and guides and utilizes the wind strength; the specific scheme is as follows:
including platform/station room region, subway tunnel, station track area, platform shield door in the subway station, its characterized in that: one or more tunnel shielding doors for blocking air flow are arranged in a subway tunnel adjacent to a station track area, and the states of the tunnel shielding doors comprise opening, partial closing and closing; the tunnel shielding door comprises a door body, a power mechanism and a control device, wherein the control device sends an instruction to the power mechanism, and the power mechanism drives the door body to perform opening, partial closing and closing actions;
The subway train air-conditioning system comprises an entrance front tunnel shield door, a tunnel shield door and a control system, wherein the tunnel shield door is arranged in a subway tunnel adjacent to a station rail running area in front of the entrance direction of a subway train and used for blocking air flow;
The tunnel shield door in front of the station-entering keeps a closed state or a partially closed state before the subway train enters the station, and the air flow between a station rail running area and the subway tunnel in front of a driving direction is blocked or weakened when the subway train enters the station, so that the piston wind strength of the subway train entering the station is enhanced; the shield door of the tunnel in front of the station is opened after the subway train enters the station and before the subway train leaves the station, so that the subway train can normally pass through the subway tunnel at the position of the shield door in front of the station.
the subway train platform comprises a tunnel shielding door at the rear of an exit station, wherein the tunnel shielding door is arranged in a subway tunnel adjacent to a station track area behind the exit direction of a subway train and used for blocking air flow;
The tunnel shielding door at the rear of the station-exit keeps an open state before the subway train enters the station, so that the subway train can normally pass through the subway tunnel at the position of the tunnel shielding door at the rear of the station-exit; the tunnel shield door behind the departure is closed or partially closed after the subway train enters the station and before the subway train leaves the station, and when the subway train leaves the station, the air flow between the station track area and the subway tunnel behind the traveling direction is blocked or weakened, so that the piston wind strength of the subway train leaves the station is enhanced.
When wind power is excessive or wind pressure is too large and cannot be utilized, the tunnel shielding door adopts a partial closing mode, and can adapt to different running states by adjusting the opening degree of the tunnel shielding door. In addition, the tunnel shielding door is usually not completely sealed, so that a small amount of air still flows through the tunnel shielding door when the tunnel shielding door is closed, but the air flow is basically negligible.
The opening or closing time of the tunnel shielding door is controlled within 10 seconds and at most should not exceed 30 seconds so as not to obstruct the normal passing of the subway train. The invention aims to enhance the piston wind power, so the tunnel screen door and the platform screen door have higher mechanical strength and air tightness.
furthermore, ventilation means should be provided in the area where the piston wind is formed, so as to guide the piston wind and utilize it. The specific ventilation device comprises a piston air shaft, a circuitous air duct and a ventilation duct system; the ventilation duct system is used to communicate the trackside area with the platform/lobby area, such as the platform screen door mounted damper arrangement described in references 2, 3, etc.
The piston wind is utilized for ventilation directly, the efficiency is high, but under the conditions that the ventilation is not favorable or the piston wind quantity is larger than the fresh air demand quantity, the piston wind can be utilized for power generation or energy storage, for example, the air is compressed into high-pressure air by wind power and stored to realize energy storage.
The invention has the beneficial effects that:
1. the effective piston wind is limited in a space area near a station through the tunnel shielding door, so that the strength of the piston wind is enhanced, and the piston wind is reasonably utilized;
2. the shield door of the tunnel in front of the subway train enters the station is closed, so that the running resistance of the subway train entering the station can be increased, and the braking energy consumption of the subway train is reduced;
3. when the piston wind is used for wind power generation or energy storage, the path of the effective piston wind is relatively fixed and the position of the effective piston wind is close to a platform, so that the utilization rate of equipment is high and the initial investment is low.
