Description

Technical Field

[0001] The present invention relates to the technical field of building ventilation, and more particularly to an energy-saving ventilation device for building design. Background Art

[0002] Currently, during building construction, in order to make rational use of space, most buildings have at least one basement floor garage for vehicle parking. Since the garage is only connected to the outside through the entrance and exit, ventilation is poor, and the air quality in the underground garage is bad. To improve this problem, ventilation pipes need to be built in the garage during construction. Although there are ventilation pipes in the building currently, and wind caps connected to the ventilation pipes are installed on the top of the building for ventilation, the ventilation efficiency is low. When the building is relatively tall, only the upper floors of the building can achieve ventilation, and the dirty air in the lower floors of the building is difficult to ventilate through the ventilation pipes. Moreover, the garage is located on the bottom floor of the building, resulting in even worse ventilation effects. Summary of the Invention

[0003] The present invention is proposed to solve the above problems, and provides an energy-saving ventilation device for building design.

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

[0005] An energy-saving ventilation device for building design includes an air intake system and an exhaust system. The air intake system includes a plurality of air intake columns built on the top of the building and an air intake diverter fixed on the inner top of the garage. The exhaust system includes a plurality of exhaust columns built on the top of the building and an exhaust diverter fixed on the inner top of the garage. The air intake diverter and the exhaust diverter are both connected to an inlet and outlet air pipe. A motor is fixed at the upper end of the air intake column, and an air intake impeller is rotatably installed on the inner top of the air intake column.

A third ventilation net is embedded in the third ventilation hole.

[0009] Furthermore, the reversing pipe is internally partitioned by a partition plate to form a first communication channel and a second communication channel.

[0010] Furthermore, the intake diverter is internally partitioned by a partition plate into a third chamber and a fourth chamber. The third chamber communicates with one end of the first communication channel, and the fourth chamber communicates with one end of the second communication channel. The third chamber communicates with the intake column and the intake cavity. A third gate valve is fixed at one end of the third chamber near the intake cavity. One end of the fourth chamber communicates with the air outlet cavity, and the other end of the fourth chamber is closed. A fourth gate valve is fixed at one end of the fourth chamber near the air outlet cavity. The third gate valve and the fourth gate valve are solenoid valves, and the third gate valve and the fourth gate valve are electrically connected to the photovoltaic power generation system.

[0011] Furthermore, the exhaust diverter is internally partitioned by a partition plate into a first chamber and a second chamber. The first chamber communicates with the other end of the first communication channel, and the second chamber communicates with the other end of the second communication channel. The second chamber communicates with the exhaust column and the intake cavity. A second gate valve is fixed at one end of the second chamber near the intake cavity.

Detailed implementation manners

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figures 1-7 As shown, an energy-saving ventilation device for building design includes an air intake system 1 and an exhaust system 2. The air intake system 1 controls the external air to enter the garage after filtering, and the exhaust system exhausts the dirty air in the garage. The air exchange and circulation in the garage is realized through the cooperation of the air intake system 1 and the exhaust system 2. The air intake system 1 includes a plurality of air intake columns 101 built on the roof of the building and an air intake diverter 104 fixed on the top of the garage. The exhaust system 2 includes a plurality of exhaust columns 201 built on the roof of the building and an exhaust diverter 207 fixed on the top of the garage. The air splitter 104 and the exhaust splitter 207 are both connected to the inlet and outlet ducts 3, which are fixed to the top of the garage by hanging screws. Multiple inlet and outlet ducts 3 are distributed at different positions of the garage to achieve ventilation at different positions. A motor 103 is fixed to the upper end of the air intake column 101, and an air intake impeller 108 is rotatably installed at the top of the air intake column 101. The air intake impeller 108 is connected to the motor 103 by transmission. An air filter 107 is fixed to the lower end of the air intake column 101 through a detachable connection. A connecting rod for connecting the air intake column 101 is fixed to the side wall of the upper end of the air intake column 101. The air intake pipe 109 of the inner cavity of the column 101 has a one-way valve 112 fixed therein. The motor 103 drives the air intake impeller 108 to rotate so as to pump the external air into the air intake column 101. The air entering the air intake column 101 can enter the air intake diverter 104 after being filtered by the air filter 107, and then circulate into the garage. The upper end of the exhaust column 201 is fixed with a self-rotating hood 203. The top of the exhaust column 201 is rotatably installed with an exhaust impeller 206. The exhaust impeller 206 is transmission-connected to the self-rotating hood 203. 01 A first ventilation hole 204 is formed on the side wall near the exhaust impeller 206, and a first ventilation net 205 is embedded in the first ventilation hole 204. The self-rotating hood 203 will rotate automatically under the drive of natural wind. When the self-rotating hood 203 drives the exhaust impeller 206 to rotate, negative pressure can be generated so that the dirty air in the garage can be discharged. A photovoltaic power generation system 5 is fixed on the roof of the building. The photovoltaic power generation system 5 includes photovoltaic power generation panels and batteries, which are used to convert light energy into electrical energy for power supply, thereby reducing energy consumption. The photovoltaic power generation system 5 is electrically connected to the motor 103.

[0025] In this embodiment, the number of intake columns 101 and exhaust columns 201 is the same. Each intake column 101 is connected to an intake diverter 104, and each exhaust column 201 is connected to an exhaust diverter 207. The intake diverter 104 and the exhaust diverter 207 are respectively located at both ends of the garage, facilitating ventilation and air exchange at different positions in the garage. A set of intake diverter 104 and exhaust diverter 207 with corresponding positions are connected by a reversing pipe 4, and air exchange at both ends of the garage can be achieved through the reversing pipe 4.

[0026] In this embodiment, the inner cavities of all the intake columns 101 are connected through a first connecting pipe 102, and the inner cavities of all the exhaust columns 201 are connected through a second connecting pipe 202. When one or more of the motors 103 and self-rotating wind caps 203 fail, the ventilation system can still operate normally, avoiding affecting normal ventilation.

[0027] In this embodiment, the intake and exhaust pipe 3 is internally partitioned by a partition plate 301 into an intake cavity 302 and an exhaust cavity 303. A second ventilation hole 304 communicating with the exhaust cavity 303 is formed at the end of the intake and exhaust pipe 3. A second ventilation net 305 is embedded in the second ventilation hole 304. A third ventilation hole 306 communicating with the intake cavity 302 is formed on the side wall of the intake and exhaust pipe 3 near the second ventilation hole 304. A third ventilation net 307 is embedded in the third ventilation hole 306. The dirty air in the garage can enter the exhaust cavity 303 through the second ventilation hole 304 and then be discharged. At the same time, clean air can flow into the intake cavity 302 and then be discharged into the garage through the third ventilation hole 306, ensuring the freshness of the air in the garage.

[0028] In this embodiment, the reversing pipe 4 is internally partitioned by a partition into a first communication channel 401 and a second communication channel 402. The two different communication channels communicate with different cavities, realizing the circulation of air at both ends of the garage.

[0029] In this embodiment, the intake diverter 104 is internally partitioned by a partition into a third chamber 105 and a fourth chamber 106. The third chamber 105 is connected to one end of the first communication channel 401, and the fourth chamber 106 is connected to one end of the second communication channel 402. The third chamber 105 communicates with the intake column 101 and the intake cavity 302. A third gate valve 110 is fixed at one end of the third chamber 105 near the intake cavity 302. One end of the fourth chamber 106 communicates with the exhaust cavity 303, and the other end of the fourth chamber 106 is closed. A fourth gate valve 111 is fixed at one end of the fourth chamber 106 near the exhaust cavity 303. The third gate valve 110 and the fourth gate valve 111 are solenoid valves, facilitating remote control of opening and closing. The third gate valve 110 and the fourth gate valve 111 are electrically connected to the photovoltaic power generation system 5. By controlling the opening and closing of the third gate valve 110 and the fourth gate valve 111, the clean air entering the garage can be controlled to enter the garage from both ends of the garage.

[0030] In this embodiment, the exhaust diverter 207 is internally partitioned into a first chamber 208 and a second chamber 209 by a partition. The first chamber 208 communicates with the other end of the first communication channel 401, and the second chamber 209 communicates with the other end of the second communication channel 402. The second chamber 209 communicates with the exhaust column 201 and the intake chamber 302. A second gate valve 211 is fixed at one end of the second chamber 209 close to the intake chamber 302. One end of the first chamber 208 communicates with the outlet chamber 303, and the other end of the first chamber 208 is closed. A first gate valve 210 is fixed at one end of the first chamber 208 close to the outlet chamber 303. The first gate valve 210 and the second gate valve 211 are solenoid valves, which are convenient for remote control of opening and closing. The first gate valve 210 and the second gate valve 211 are electrically connected to the photovoltaic power generation system 5. By controlling the opening and closing of the first gate valve 210 and the second gate valve 211, the dirty air at both ends of the garage can be pumped out of the garage.

[0031] The working principle of the present invention is as follows: There are three ventilation modes during use. First, the fourth gate valve 111 and the first gate valve 210 are in the closed state, and the third gate valve 110 and the second gate valve 211 are in the open state. At this time, under the action of the motor 103, the external air enters the garage after being filtered through the third chamber 105 and the air inlet and outlet pipe 3 below the intake diverter 104. At the same time, the dirty air in the garage enters the second chamber 209 through the air inlet and outlet pipe 3 below the exhaust diverter 207 under the action of the self-rotating wind cap 203 and then is discharged from the first ventilation hole 204. Second, the fourth gate valve 111 and the first gate valve 210 are in the open state, and the third gate valve 110 and the second gate valve 211 are in the closed state. At this time, under the action of the motor 103, the external air enters the third chamber 105 after being filtered and then enters the first chamber 208 through the first communication channel 401, and finally enters the garage through the air inlet and outlet pipe 3 below the exhaust diverter 207. At the same time, the dirty air in the garage enters the fourth chamber 106 through the air inlet and outlet pipe 3 below the intake diverter 104 under the action of the self-rotating wind cap 203, then enters the second chamber 209 through the second communication channel 402, and finally is discharged from the first ventilation hole 204. Third, the fourth gate valve 111, the first gate valve 210, the third gate valve 110, and the second gate valve 211 are all in the open state. The air pumped in by the motor 103 enters the third chamber 105 and is then split. Part of the air is directly discharged to one end of the garage through the air inlet and outlet pipe 3 below the intake diverter 104, and the other part of the air enters the first communication channel 401 and then enters the first chamber 208 and is discharged to the other end of the garage through the air inlet and outlet pipe 3 below the exhaust diverter 207. At the same time, the air in the garage enters the fourth chamber 106 and the second chamber 209 respectively through the air inlet and outlet pipes 3 at both ends of the garage and is then discharged to the outside through the first ventilation hole 204 under the action of the exhaust impeller 206.

[0032] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
