Technical Field
[0001] The present invention relates to a portal, in particular to an energy-saving portal control system. Background Art
[0002] In shopping malls with a large number of people, a relatively large number of door leaves are often set at the exits for normal and fire-fighting use. However, the energy consumption of commercial air conditioners accounts for a large proportion. The door leaves have poor sealing and unreasonable opening management, resulting in a large amount of cold air overflowing in summer and a large amount of cold wind penetrating in winter. This not only consumes a large amount of air-conditioning energy but also reduces the shopping experience of customers. With the development of social economy, although the commercial entrances have been upgraded to the form of portals later, due to poor entrance management and irregular flow of people, setting up portals can reduce the loss of air-conditioning energy to a certain extent, but still cannot achieve a satisfactory effect. Therefore, there is an urgent need to develop a portal control system that can significantly reduce the air-conditioning energy consumption in winter and summer and improve the customer experience. Summary of the Invention
[0003] The purpose of the present invention is to provide an energy-saving portal control system. The present invention has the characteristics of being able to significantly reduce the air-conditioning energy consumption in winter and summer, thereby achieving the purpose of energy conservation.

[0025] A second air curtain machine C2 is provided at the top of the third movable door D3, and a first air curtain machine C1 is provided at the top of the second movable door D2.
[0026] Windproof brushes F2 are installed on the bottom surfaces of the first movable door D1, the second movable door D2, the third movable door D3, and the fourth movable door D4.
[0027] The bottom door shafts of the first movable door D1, the second movable door D2, the third movable door D3, and the fourth movable door D4 are all connected to a ground shaft coupler H1 for rotation, and the ground shaft coupler H1 is connected to a generator set E1.
[0028] The ground shaft coupler H1 includes a bearing E2 fixed to the ground, and a long shaft E3 connected to the movable door shaft is arranged inside the bearing E2.
[0029] The generator set E1 includes a large gear E4 fixed to the bottom of the long shaft E3, the large gear E4 meshes with a small gear E5, the small gear E5 is connected to a generator E7 through a short shaft E6, the generator E7 is connected to a rectifier circuit board E8, and the rectifier circuit board E8 is connected to a storage battery E9.
[0030] An electric heating wire is embedded in the glass of the door pocket, and the electric heating wire is connected to the generator set E1.
[0031] The first movable door D1 and the second movable door D2 open from the door pocket to the outside, and the third movable door D3 and the fourth movable door D4 open from the indoor to the door pocket.
[0032] The door pocket is enclosed by a first fixed glass G1, a second fixed glass G2, a third fixed glass G3, and a fourth fixed glass G4.
[0033] By setting the first electric sliding door M1 and the second electric sliding door M2, the door pocket control system is divided into a first channel, a second channel, and a third channel. On the left side of the first channel is the fourth fixed glass G4, and the fourth fixed glass G4 is used to enclose the door pocket space. The top and bottom surfaces of the fourth fixed glass G4 are sealed with waterproof glass glue F1. Electric heating wires are embedded inside the first to fourth fixed glasses for heating in winter to increase the temperature of the door pocket in winter. The first movable door D1 is installed on the outdoor side of the fourth fixed glass G4, and the first movable door D1 opens from the door pocket to the outside. The top surface of the first movable door D1 is sealed with waterproof glass glue F1, and a windproof brush F2 is installed on the bottom surface to prevent cold air from penetrating. The first movable door is vertically arranged with male-female joints to reduce air penetration through the door gap.
[0034] On the right side of the first movable door D1 is connected the first fixed glass G1. Near the indoor side of the fourth fixed glass G4, the third movable door D3 is installed. The third movable door D3 opens from the indoor side to the vestibule. On the top of the third movable door D3, the second air curtain machine C2 is installed. The second air curtain machine C2 sucks air from the indoor side and sends it into the vestibule to maintain positive pressure inside the vestibule, mainly used to prevent cold air penetration in winter. On the right side of the third movable door D3 is connected the third fixed glass G3, and on the third fixed glass G3, the first electric sliding door M1 is installed. On the first fixed glass G1, the second electric sliding door M2 is installed. The first electric sliding door M1, the second electric sliding door M2, the first fixed glass G1 and the third fixed glass G3 form the second passage. On the right side of the first fixed glass G1, the second movable door D2 is installed. The second movable door D2 opens from the vestibule to the outdoor side. On the top of the second movable door D2, the first air curtain machine C1 is installed. The first air curtain machine C1 sucks air from inside the vestibule and sends it to the inner side of the second movable door D2 as its air curtain to block the intrusion of cold outdoor air. On the right side of the third fixed glass, the fourth movable door D4 is installed. The third movable door D3 opens from the indoor side to the vestibule. The second movable door D2 and the fourth movable door D4 are connected through the second fixed glass and jointly form the third passage.
[0035] The bottoms of the first movable door, the second movable door, the third movable door and the fourth movable door are connected to the generator set E1 through the floor hinge H1.
[0036] The generator set E1 is fixed to the basement roof surface through the suspension rod F4 and the channel steel F3.
[0037] The floor hinge H1 consists of a bearing E2 and a long shaft E3. The top of the long shaft E3 is fixed to the bottom of the first movable door. The throat of the long shaft E3 is connected to the bearing E2. The bearing E2 bears the load of the movable door on one hand and rotates with the long shaft E3 on the other hand. The bottom of the long shaft E3 is connected to the large gear E4. The large gear E4 is connected to the small gear E5. Through the connection of the large and small gears, the small gear obtains a greater rotational speed. The small gear E5 is connected to the generator set E1 through the short shaft E6. In the generator set E1, below the short shaft E6 is connected to the generator E7. The generator E7 is responsible for converting the mechanical energy of the opening and closing of the movable door into electrical energy. The generator E7 is connected to the storage battery E9 through the rectifier circuit board E8. The function of the rectifier circuit board E8 is such that the movable door can charge the storage battery E9 whether it is in the opening or closing movement. The storage battery E9 uses electrical energy through the wire E10 for electrical heating wires, air curtain machines and lighting and other electrical equipment inside the fixed glass.
[0038] The control strategy of the above energy-saving door control system is as follows: It can be divided into the following four modes
[0039]
[0040] Mode 1 - Summer: People flow from indoors through the third movable door D3 into the first passage, pass through the first electric sliding door M1 into the second passage, pass through the second electric sliding door M2 into the third passage, and reach the outdoors through the second movable door D2. The flow of people entering the room from the outdoors is just the opposite of the previous one. In this way, the people flow moves in a zigzag pattern, and the indoor cold air also flows in a zigzag pattern in the vestibule, increasing the residence time of the cold air in the vestibule and increasing the flow resistance of the cold air. By the movement of people in and out driving the movable door to rotate, the door shaft drives the cardan shaft H1 to rotate accordingly. The generator E7 converts the mechanical energy of the rotating door shaft into electrical energy, and the electrical energy is stored in the battery E9 through the rectifying circuit board E8. The electrical energy of the battery E9 is preferentially used for the air curtain machine. When the second movable door D2 is opened, it triggers the first air curtain machine to turn on, blocking the overflow of cold air and further reducing the risk of cold air loss.
[0041] Mode 2 - Winter: People flow from indoors through the third movable door D3 into the first passage, pass through the first electric sliding door M1 into the second passage, pass through the second electric sliding door M2 into the third passage, and reach the outdoors through the second movable door D2. The flow of people entering the room from the outdoors is just the opposite of the previous one. In this way, the people flow moves in a zigzag pattern, and the outdoor cold wind also flows in a zigzag pattern in the vestibule, increasing the residence time of the cold wind in the vestibule and increasing the flow resistance of the cold air. By the movement of people in and out driving the movable door to rotate, the door shaft drives the cardan shaft H1 to rotate accordingly. The generator E7 converts the mechanical energy of the rotating door shaft into electrical energy, and the electrical energy is stored in the battery E9 through the rectifying circuit board E8. The electrical energy of the battery E9 is preferentially used for heating the fixed glass and the air curtain machine. When the second movable door D2 is opened, it triggers the first air curtain machine to turn on. When the third movable door D3 is opened, it triggers the second air curtain machine to turn on, maintaining a positive pressure inside the vestibule and blocking the invasion of cold wind, further reducing the risk of cold wind invasion. In addition, a small part of the invading cold wind mixes with the hot air of the air curtain machine, combined with the heat radiation of the fixed glass, keeping the environment inside the vestibule within a comfortable temperature range.
[0042] Mode 3 - Transition Season: The first electric sliding door M1 and the second electric sliding door M2 are closed. Part of the people flow from indoors through the third movable door D3 into the first passage and reach the outdoors via the first movable door D1. Another part of the people flow from indoors through the fourth movable door D4 into the third passage and reach the outdoors via the second movable door D2. The flow of people entering the room from the outdoors is just the opposite of the previous one. By the movement of people in and out driving the movable door to rotate, the door shaft drives the cardan shaft H1 to rotate accordingly. The generator E7 converts the mechanical energy of the rotating door shaft into electrical energy, and the electrical energy is stored in the battery E9 through the rectifying circuit board E8. The electrical energy of the battery E9 is preferentially used for lighting. In the transition season, the maximum amount of outdoor fresh air is introduced to cool the indoor environment for free. By directly increasing the number of movable doors, shortening the distance for air to enter the room, and reducing the air entry resistance, free fresh air cooling is achieved, improving the indoor environment.
[0043] Mode 4 evacuation: When entering the evacuation mode, the first electric sliding door M1 and the second electric sliding door M2 are closed, and a part of the flow of people enters the first channel from the room through the third movable door D3, and reaches the outside through the first movable door D1, and the other part of the flow of people enters the third channel from the room through the fourth movable door D4, and reaches the outside through the second movable door D2. By opening all four movable doors, direct door-to-door evacuation is achieved, which increases the evacuation area, shortens the evacuation distance, and meets the evacuation safety requirements.
[0044] As an improvement, when operating in mode 1 in summer and mode 2 in winter, when the corresponding movable door is opened and the door shaft rotates forward, the corresponding air curtain machine is linked to open; when the corresponding movable door is closed and the door shaft rotates reversely, the corresponding air curtain machine is linked to close, which can save the operating energy consumption of the air curtain machine.
