Description
Technical Field
The invention relates to the technical field of elevator ventilation, in particular to an elevator air supply system and method.
Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
The elevator car is a limited Space (defined according to safety science: limited Space defined Space means Space which can accommodate personnel, has limited access and is designed to be a Space which is not suitable for the personnel to occupy for a long time). Elevator personnel in public places are frequently used and closely contacted with each other, so that hidden dangers are brought to public health safety, particularly to health prevention and control in the period of preventing infection sources from spreading. According to the existing recognition, good ventilation measures in confined spaces are the most direct, cost-effective way to guarantee public health safety and to prevent or reduce the spread of pollution.
The ventilation of the elevator in the prior art is generally realized by adopting the following technologies:
(1) set up fan or fan on the elevator car, directly supply air in to the elevator car, the problem that this kind of mode exists is:
generally, an elevator car is disposed in a closed elevator shaft without free flow and exchange with the outside air, and the car is provided with only ventilation holes having an area of about 1% more for air exchange with the elevator shaft. Therefore, the airflow of the fan or the blower can be repeatedly stirred only in a narrow closed space of the elevator car to form an airflow loop (vortex), so that the air in the elevator car cannot be purified, and the spreading of pollutants (such as aerosol spreading) is aggravated.
Therefore, experts point out that for places without special fresh air systems, the hidden danger risk of cross infection exists when fans or blowers are used;
(2) an exhaust device is arranged on the elevator or the shaft, so that air in the elevator shaft is pushed by the operation of the elevator or is sucked into external airflow by utilizing negative pressure air difference to supply air to the elevator car. In fact, this is a natural ventilation based on local air discharge conditions, because it is difficult to achieve a process layout in the elevator shaft that meets the requirements of natural ventilation, such as the area of the ventilation air outlet, according to the elevator safety specifications. Therefore, the residual heat, the residual moisture or the polluted gas formed by the operation of the elevator are easy to form turbulent flow in the well, and the diffusion of harmful substances in the elevator space is accelerated. In addition, the air exhaust capacity is greatly weakened due to the pressure relief influence of hoistway space, door opening and closing, holes and the like.
Therefore, in the prior art, the elevator air supply systems are all independently arranged, and the common air supply device with other fresh air systems (such as a fresh air system of a hospital and a fire-fighting air supply system) cannot be realized; the elevator space occupied space is increased to a certain extent, and harmful substances in the elevator space are not discharged in time.

An air supply channel 2 is arranged in the elevator shaft, and the air supply channel 2 is connected with an air supply device 6; the air supply channel 2 may be provided in the form of an air supply duct; an air outlet is arranged at a preset position (such as the inside of a hoistway and a landing position) on the air supply pipeline; the number of the air outlets can be one or more, and the air outlets are used for being matched with the air inlets 9 on the elevator car 1 and conveying air into the elevator car 1; alternatively, the gas in the elevator car 1 is discharged.
Set up mechanical air valve on the air outlet, this mechanical air valve's structure includes: the sliding chutes 14, at least one blade 13 and the driving rod 12 are arranged on two sides of the air supply opening 4 in parallel along a set direction;

When the driving rod pushes the air supply valve open under the thrust of the impact bow, the spring is compressed, and when the thrust received by the driving rod is reduced, the driving rod can return to the original position under the action of the elastic force of the spring.
A roller is provided at an end of the drive lever 12 that contacts the mechanical bow in order to reduce damage to the drive lever 12 or the mechanical bow 11 caused by friction between the drive lever 12 and the mechanical bow 11.

When the air supply valve is kept in a closed state, fresh air of an air supply pipeline in the elevator shaft 10 cannot enter the elevator car 1; when the blast valve is opened, the air inlet 9 of the elevator car 1 is over against the blast port 4, and fresh air enters the elevator car 1 through the blast valve.
Referring to fig. 2(a) - (c), the specific process of opening and closing the upper valve blade 13 by the mechanical pantograph 11 in cooperation with the blast valve is as follows:
the air supply device 6 is started, and the mechanical impact bow 11 moves along with the elevator car 1; setting the initial position of the air supply valve to be that the air supply outlet 4 is completely closed;
when one inclined section of the mechanical impact bow 11 contacts the driving rod 12 of the blast valve, a horizontal component force is applied to the driving rod 12; the driving rod 12 drives one end of the blade 13 to move towards the horizontal thrust direction, and the other end of the blade 13 moves towards the direction of increasing the opening of the air supply outlet 4 along the chute 14; at the moment, the air supply outlet 4 is opened, and outside air is sent into the elevator car 1 through the air inlet 9;
referring to fig. 3(a) - (b), when the elevator car 1 moves to the position where the straight line section of the mechanical pantograph 11 contacts the driving rod 12, the other end of the vane 13 slides along the chute 14 to the position where the opening of the air blowing opening 4 is maximum; the opening of the air supply outlet 4 is the largest; the airflow sent into the elevator car 1 is also maximum; in order to ensure the maximum air supply efficiency, the air supply outlet 4 and the center of the air inlet 9 are positioned on the same straight line.
The elevator car 1 continues to move, when the other inclined section of the mechanical impact bow 11 contacts the driving rod 12, the thrust borne by the driving rod 12 is gradually reduced, the driving rod 12 drives one end of the blade 13 to move in the direction opposite to the horizontal thrust, the other end of the blade 13 moves along the chute 14 in the direction of reducing the opening of the air supply outlet 4, finally, the mechanical impact bow 11 is completely separated from the driving rod 12, referring to fig. 4(a) - (b), the driving rod 12 is reset under the elastic force of the spring 17, and the other end of the blade 13 slides along the chute 14 to the initial position; the air supply port 4 is completely closed, and air supply is stopped.

As an alternative embodiment, an air outlet leading to the outside of the room and connected to the supply air duct in the shaft is provided in the elevator shaft 10 or in the machine room structure. The other end of the air supply channel 2 is connected with an air exhaust device which is communicated with the outside.
An exhaust valve 5 is arranged on the exhaust outlet; the exhaust valve 5 adopts a one-way air valve (such as an excess pressure type shutter) which is automatically controlled without energy consumption, and the one-way exhaust valve 5 is opened at fixed time or through excess pressure; so as to achieve convection and exchange of air in the elevator car 1 and outdoor air.
Specifically, when the electric blower valve 3 is in the closed state, the blower duct in the elevator shaft 10 is free of fresh air. At this stage, in the running and stopping processes of the elevator, the mechanical impact bow 11 still drives the air supply valve to open along with the running of the elevator, and waste heat, residual moisture or polluted gas generated in the elevator car 1 enters the air supply pipeline under the action of the hot pressing effect and is discharged out of a room through the automatic one-way opening exhaust valve 5.
