Description

Technical Field

[0001] This invention belongs to the field of green building technology, specifically a ventilation and energy-saving device and method for green buildings. Background Art

[0002] Building ventilation equipment is generally installed on the wall of a building to ventilate the room. It is generally composed of an air duct and a fan on the air duct. The air duct is generally equipped with a heat exchange device to heat the cold air entering the room during winter use, thereby keeping the room warm and improving the user's comfort. Generally, heat exchange equipment uses a heating coil. When air flows along the path where the heating coil is installed, the heating coil heats the air. However, there are the following defects:

[0003] The heating temperature of the heating coil can only be controlled by the remote control to control the input current. When the heating temperature is controlled, when the air inlet speed is adjusted to a small amount, when the air flows through the heating path, the amount of air circulating is reduced while the heating time remains unchanged, which can easily cause the temperature of the air blown into the room to increase, causing the temperature of the air blown into the room to rise. The amount of air blown in and the temperature at the time of blowing in cannot be adaptively adjusted, causing the temperature of the air blown into the room to be unstable, affecting the user experience and resulting in poor energy-saving effects.

[0018] S3, Air intake: Turn on the fan to draw outside air through the inside of the heating box and blow it into the room through the air inlet;

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1) During operation, two baffles are symmetrically arranged on one side of the first air inlet baffle, and an inclined plate is arranged on the side of the two baffles away from each other. When the movable frame moves toward the first air inlet baffle, the push rod generates pressure on the inclined plate, pushing the two baffles closer to each other, thereby adjusting the air inlet area on the first air inlet baffle, making it convenient to adjust the air inlet speed.

[0024] 3) During operation, by arranging the first side plate on the side of the power connection block to be located above the second side plate on the side of the power connection block close to the first air inlet baffle, after the conductive plate moves toward the heating box, the heating strips on the side of the conductive plate close to the first air inlet baffle can all be connected to the circuit. The smaller the air inlet area, the fewer the number of heating strips connected to the circuit, and the shorter the heating length of the air, so that the heating time and the air inlet volume are adaptively adjusted to ensure stable air inlet temperature.

[0025] 4) During operation, the rotating ring on the movable column contacts the friction plate. When the movable frame moves and adjusts, the rotating ring rotates continuously under the action of friction, and then continuously generates electricity through the small generator and inputs it into the electromagnet, driving the movable column toward the heating box and driving the two conductive plates away from each other, so that the power supply and heating are stopped during the movement, ensuring safety of use and avoiding wear of the power connection parts during the movement.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0043] Depend on Figure 1-13 The present invention relates to a ventilation energy-saving device for green buildings, comprising an air duct 1, a solar panel 2 being installed on the top wall of the air duct 1, a battery 3 being installed at the bottom end of the air duct 1, a fan 4 being installed at one end of the air duct 1, an end of the air duct 1 away from the fan 4 being configured as an air inlet, a first air inlet baffle 5 and a second air inlet baffle 6 being installed inside the air duct 1, an air inlet regulating assembly 7 being installed at the end of the air duct 1 away from the fan 4, and the air inlet regulating assembly 7 being located on the side of the first air inlet baffle 5 away from the second air inlet baffle 6.

[0044] The air inlet adjustment component 7 includes a receiving groove 701 symmetrically opened on the inner top wall and the inner bottom wall of the air outlet of the air duct 1, and a guide rod 702 is symmetrically installed between the upper and lower receiving grooves 701. Two baffles 703 are symmetrically arranged on one side of the first air inlet baffle 5 away from the second air inlet baffle 6. An inclined plate 704 is installed at one end of the upper and lower baffles 703 away from each other. The baffles 703 are slidably connected to the guide rod 702.

When the moving frame 805 moves toward the side of the first air inlet baffle 5, pressure is generated on the inclined plate 704 through the push rod 807, pushing the two baffles 703 closer to each other, thereby adjusting the air inlet area on the first air inlet baffle 5 The air intake speed is adjusted conveniently. In the original state, the upper and lower baffles 703 do not block the air intake slot on the first air intake baffle 5. When the moving frame 805 moves toward the first air intake baffle 5, the inclined plate 704 on the baffle 703 is pressured by the top rod 807, which can push the upper and lower baffles 703 closer to each other, so that the baffles 703 block the air intake slot on the first air intake baffle 5, and the greater the moving distance, the larger the blocked area of ​​the air intake slot on the first air intake baffle 5, thereby adjusting the air intake area at the first air intake baffle 5.

Vertical plates 902 are equidistantly installed inside the heating box 901, and heating strips 903 are equidistantly installed on the vertical plates 902.

A third contact 9077 is installed at the bottom end of the first side plate 9075. A second side plate 9077 is installed on the side of the power-connecting block 9071 near the second air inlet baffle 6. The top of the second side plate 9078 is equipped with a fourth contact 9079.

The first side plate 9075 is located above the second side plate 9078 on the power receiving block 9071 adjacent to the first air inlet baffle 5. The two adjacent end conductive strips 9076 are in contact.

[0046] The mobile power connection component 10 includes two side conductive strips 1001 symmetrically installed on the inner wall of one side of the air duct 1 between the first air inlet baffle 5 and the second air inlet baffle 6, and a power connection post 1002 is symmetrically installed on the side of the mobile frame 805 close to the side conductive strip 1001. The two power connection posts 1002 are in contact with the two side conductive strips 1001 respectively, and the two side conductive strips 1001 are electrically connected to the positive and negative poles of the battery 3 respectively. A movable groove 1003 is provided on the inner top wall and the inner bottom wall of the mobile frame 805. A side groove 1006 is provided on the end of the movable groove 1003 away from the side conductive strip 1001. A conductive plate 1004 is slidably installed inside the movable groove 1003, and heating strips 903 are equidistantly installed on the vertical plate 902. The mobile frame 805 stops After stopping, the conductive plates 1004 on the upper and lower sides of the movable frame 805 are close to each other to press the power block 9071 toward the vertical plate 902, so that the heating strip 903 is connected to the circuit, which is convenient for heating the air. The conductive plate 1004 is provided with an arc surface 1005 on the side close to the heating box 901. The two arc surfaces 1005 are electrically connected to the two power posts 1002 through wires. The first side plate 9075 on the side of the power block 9071 is located above the second side plate 9078 on the side of the power block 9071 close to the first air inlet baffle 5. After the conductive plate 1004 moves toward the heating box 901, the heating strips 903 on the side of the conductive plate 1004 close to the first air inlet baffle 5 can be connected to the circuit. The smaller the air inlet area, the more heating strips 903 are connected to the circuit. The smaller the number, the smaller the number, because the movable frame 805 moves and drives the conductive plate 1004 to move to the target position, the heating strips 903 on the side of the conductive plate 1004 close to the first air inlet baffle 5 are connected to the circuit, while the heating strips 903 on the side of the conductive plate 1004 away from the first air inlet baffle 5 are not connected to the circuit, so that the closer the conductive plate 1004 is to the first air inlet baffle 5, the fewer heating strips 903 connected to the circuit, the shorter the heating path length, and the shorter the heating length of the air, so that the heating time and the air intake volume are adaptively adjusted to ensure the stability of the air intake temperature, and a side tube 1007 is installed on the side of the movable frame 805 away from the side conductive strip 1001, and the upper and lower sides of the side tube 1007 are provided with connecting grooves 1008, and the interior of the side tube 1007 is movably installed with movable The movable column 1009 is located at the upper and lower sides of one end of the inner part of the side tube 1007, and the two connecting rods 1010 are hingedly installed. The two connecting rods 1010 pass through the two side grooves 1006 and are hinged to the two conductive plates 1004. A third spring 1011 is installed at the end of the movable column 1009. One end of the third spring 1011 is fixedly connected to the inner wall of the end of the side tube 1007. A magnetic block 1013 is installed at one end of the movable column 1009, and an electromagnet 1012 is installed on the inner wall of the end of the side tube 1007. A rotating ring 1014 is rotatably installed on the outer side of the other end of the movable column 1009. A gear ring 1015 is installed on the side of the rotating ring 1014 close to the moving frame 805, and a gear 1016 is meshed and installed below the gear ring 1015.Gear 1016 is fixedly connected to the input shaft of a small generator 1017. The small generator 1017 is mounted on a mounting bracket, which is fixedly mounted on the bottom of the movable column 1009. The small generator 1017 is electrically connected to the electromagnet 1012. A friction plate 1018 is mounted on the inner wall of the air duct 1 away from the side conductive strip 1001. The friction plate 1018 contacts the axial outer wall of the rotating ring 1014. The rotating ring 1014 on the movable column 1009 contacts the friction plate 1018. When the movable frame 805 is moved and adjusted, the rotating ring 1014 continuously rotates under the action of friction, and then continuously generates electricity through the small generator 1017 and transmits it to the electromagnet 1012, driving the movable column 1009 toward the heating box 901, driving the two conductive plates 1004 away from each other, so that the power supply and heating are stopped during the movement, ensuring safety in use and avoiding wear on the power connection parts during the movement.

[0047] Working principle: When the equipment is installed, a mounting slot is preset on the wall, and the air duct 1 is installed inside the mounting slot, so that the air inlet on the air duct 1 is located indoors, and one end of the air duct 1 provided with the fan 4 is located outdoors. During normal use, the solar panel 2 can absorb solar energy, and then convert the solar energy into electrical energy through the energy conversion device and store it inside the battery 3, which is green and energy-saving. When ventilation is performed, the fan 4 is turned on to drive the outside air to pass through the inside of the heating box 901 and blow into the room from the air inlet. When the air intake intensity needs to be reduced, the drive motor 802 is turned on to rotate the screw 801. Since the screw 801 is threadedly connected to the movable frame 805, the movable frame 805 is driven to move toward the side of the first air inlet baffle 5, thereby generating pressure on the inclined plate 704 through the top rod 807, pushing the upper and lower baffles 703 closer to each other, thereby continuously reducing the air inlet port area at the heating box 901, thereby adjusting the air intake intensity;

[0048] When used in winter, the air intake needs to be heated. Turning on the output switch of battery 3 connects the heating strip 903 to the circuit via two side conductive strips 1001, two terminals 1002, and two conductive plates 1004, energizing the heating strip 903 and heating the air. Simultaneously, when the moving frame 805 moves towards the first air intake partition 5 to a predetermined position, the upper and lower conductive plates 1004 move closer together, causing one of the terminals 9071 to move towards the vertical plate 902. This causes the second contact 9074 to contact the terminal groove 904, thus energizing the corresponding heating strip 903. At the same time, due to the first side plate 907 on one side of the terminal block 9071... 5 is located above the second side plate 9078 on the side of the electrical block 9071 near the first air inlet baffle 5. When one of the electrical blocks 9071 is pressed, it drives all the electrical blocks 9071 near the first air inlet baffle 5 to move towards the vertical plate 902. This allows the heating strips 903 on the conductive plate 1004 near the first air inlet baffle 5 to be connected to the circuit. This allows the heating strips 903 to be energized to heat the air. The smaller the air inlet area, the closer the moving frame 805 is to the first air inlet baffle 5, the fewer the number of heating strips 903 connected to the circuit, and the shorter the heating length of the air. This allows the heating time and air inlet volume to be adaptively adjusted to ensure a stable air inlet temperature.

[0049] As the moving frame 805 moves, the outer wall of the rotating ring 1014 contacts the friction plate 1018, causing the rotating ring 1014 to rotate under friction. This rotation, in turn, drives the input shaft of the small generator 1017 to rotate via the gear ring 1015 and gear 1016. The small generator 1017 then generates electricity and inputs current into the electromagnet 1012. The energized electromagnet 1012 attracts the magnetic block 1013, pulling the movable column 1009 towards one side of the moving frame 805. This, in turn, pushes the upper and lower conductive plates 1004 away from the heating box 90 via the two connecting rods 1010. 1. Move to one side to avoid obstruction of movement. After stopping, the rotating ring 1014 stops rotating, causing the small generator 1017 to stop supplying power to the electromagnet 1012. Then, the movable column 1009 moves back, so that the conductive plate 1004 contacts the end conductive strip 9076, thereby connecting the heating strip 903 into the circuit. When the moving frame 805 moves towards the second air inlet baffle 6, the arc surface 1005 on the conductive plate 1004 can exert pressure on the end of the first side plate 9075, causing the connecting block 9071 to move towards the vertical plate 902, which facilitates the start of the movement of the moving frame 805.
