Description

Technical Field

[0001] This invention belongs to the field of building energy-saving ventilation technology, specifically a building energy-saving ventilation structure. Background Technology

[0002] Building categories are classified by function into residential buildings, public buildings, industrial buildings, and agricultural buildings; and by scale into large-scale buildings and large-scale buildings. Industrial plants refer to various buildings directly used for production or supporting production, including main workshops, auxiliary rooms, and ancillary facilities. This invention addresses ventilation within industrial plant buildings.

[0003] Chinese invention patent CN114909752A discloses an energy-saving ventilation structure for building design. The problem this patent aims to solve is that existing building ventilation equipment typically uses air conditioner outdoor unit fans to transport outside air into the room to replace the indoor air. However, this consumes a lot of electricity and has poor energy-saving effect over long-term use. This structure is powered by solar panels, making it energy-saving and environmentally friendly. It is also simple to install and disassemble, and easy to adapt to the ventilation systems of different buildings. Furthermore, it offers various ventilation modes to meet different ventilation needs.

[0004] In the aforementioned prior art, solar panels power a motor, which in turn ventilates the building. While this technology achieves energy savings, the limited power of the motor restricts the fan's rotation speed, thus affecting the building's ventilation efficiency. If the motor has a higher power output, it requires a large amount of electricity, which solar panels cannot sustain for extended periods, resulting in insufficient ventilation and reduced building efficiency. Therefore, this paper proposes an energy-saving ventilation structure to improve the building's ventilation efficiency. Summary of the Invention

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] This invention achieves high ventilation efficiency in industrial plant buildings by incorporating a second impeller, a guide pipe, and a first impeller. A dual-shaft motor drives the first impeller to rotate, which in turn drives the first transmission plate to rotate. During the rotation of the first transmission plate, the first magnets are also driven to rotate. Since there are four first magnets and eight second magnets, each rotation of the first transmission plate results in...

[0022] The second transmission plate will rotate twice, and the rotation of the second transmission plate will drive the second impeller to rotate. The high-speed rotation of the second impeller will draw air from the outside, thus ventilating the industrial plant. The rotation of the drive motor once will drive the second impeller to rotate twice, thereby reducing power consumption and improving the ventilation efficiency of the industrial plant, thus achieving the effect of high ventilation efficiency in industrial plant buildings.

[0023] This invention achieves the purpose of regulating the ventilation speed in industrial plants by incorporating an airbag, an adjusting plate, and an adjusting ring. By rotating the adjusting ring, it moves to the left under the action of the external thread of the guide pipe. During this movement, the pushing plate pushes the contact ring to the left and compresses the airbag. When one side of the airbag is under pressure, it expands and compresses one end of the adjusting plate inward, making the adjusting plate funnel-shaped with its inner diameter gradually decreasing from left to right. When air enters the inner side of the adjusting plate, it gradually gathers towards the inner side, thereby increasing the airflow velocity. When the adjusting ring is rotated in the opposite direction, the adjusting plate will match the inner diameter of the guide pipe. At this time, the air injected by the guide pipe will be dispersed through the support block and the dispersion port, thus achieving the effect of regulating the ventilation speed in industrial plants.

[0024] This invention achieves the purpose of preventing backflow during ventilation in industrial plants by incorporating a fixed plate, a sealing plate, and a connecting ring. The resistance between the connecting ring and the transmission ring limits the movement of the transmission ring, causing the transmission ring, connecting ring, and connecting block to move to the right, compressing the spring. As the connecting ring moves to the right, it pulls the inner side of the sealing plate, causing the outer end of the sealing plate to slide inside the air inlet. This causes the outer part of the sealing plate to converge towards the center of the air inlet, forming a fan shape. At this point, the fixed plate opens, and the transmission ring moves to the rightmost end of the bolt. The spring is fully compressed, and the bolt continues to rotate. The transmission ring follows the bolt's rotation. When the transmission ring is at the rightmost end of the bolt, the air inlet is fully open. When the dual-axis motor stops rotating, the spring returns to its original position and pushes the connecting ring to the left, sealing the air inlet with the sealing plate, thus achieving the effect of preventing backflow during ventilation in industrial plants.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] As shown in Figure 1 to Figure 8 As shown, this invention provides an energy-saving ventilation structure for buildings, including a ventilation pipe 1. An air inlet assembly 4 is fixedly installed on one side of the ventilation pipe 1, and a guide pipe 3 is fixedly installed on the other side of the ventilation pipe 1. An exhaust assembly 2 is threaded onto the outside of the guide pipe 3. A transmission assembly 5 is fixedly installed inside the ventilation pipe 1. A first support frame 11 is fixedly installed inside the ventilation pipe 1. A dual-shaft motor 6 is fixedly installed on the inner side of the first support frame 11. A crank arm 7 is fixedly installed on one side of the dual-shaft motor 6. An adjustment assembly 8 is movably installed inside the guide pipe 3. A first impeller 9 is fixedly installed on the other side of the dual-shaft motor 6.

[0036] A second impeller 10 is fixedly installed on one side of component 5.

[0037] The above solution involves starting the dual-shaft motor 6 to rotate the rake rod 7, opening the air intake assembly 4. Simultaneously, the dual-shaft motor 6 rotates the first impeller 9, which in turn drives the transmission assembly 5 to rotate. By increasing the speed of the second impeller 10, the exhaust effect of the second impeller 10 is improved, effectively reducing the motor power and increasing the ventilation efficiency of the industrial plant. Meanwhile, external air enters the ventilation duct 1 through the air intake assembly 4, then enters the guide pipe 3 and the regulating assembly 8. By adjusting the inner diameter of the regulating assembly 8 from left to right, the airflow gradually converges towards the center, increasing the air velocity and thus improving the ventilation effect of the industrial plant.

[0038] like Figure 2 As shown in Figures 4 and 5, the transmission assembly 5 includes a second support frame 508.

[0039] The second support frame 508 is fixedly installed on the inner wall of the ventilation pipe 1. A fixing ring 501 is fixedly installed on the inner side of the second support frame 508. A conduction block 504 is fixedly installed at equal angles in the inner ring of the fixing ring 501. A first transmission plate 502 is movably installed on one side of the inner ring of the fixing ring 501. A first magnet 503 is fixedly installed at equal angles in the inner ring of the first transmission plate 502. A second transmission plate 506 is movably installed on the other side of the inner ring of the fixing ring 501. A second magnet 507 is fixedly installed at equal angles in the outer ring of the second transmission plate 506. One side of the first transmission plate 502 is fixedly installed on one side of the first impeller 9. The first transmission plate 502 and the second transmission plate 506 are respectively movably installed on the left and right ends of the inner ring of the fixing ring 501. There are eight first magnets 503 and four second transmission plates 506. Each pair of first magnets 503 and second magnets 507 are opposite poles. One side of the second transmission plate 506 is fixedly installed on one side of the second impeller 10.

[0040] The above scheme is adopted as follows: The dual-shaft motor 6 drives the first impeller 9 to rotate, which in turn drives the first transmission plate 502 to rotate. During the rotation of the first transmission plate 502, the first magnets 503 are rotated. Since there are four first magnets 503 and eight second magnets 507, when the first transmission plate 502 rotates one revolution, the difference in the number of first magnets 503 and second magnets 507 is transmitted through the conduction block 504, causing the second transmission plate 506 to rotate two revolutions. The rotation of the second transmission plate 506 drives the second impeller 10 to rotate. The high-speed rotation of the second impeller 10 draws air from the outside, thus ventilating the industrial plant. The rotation of the drive motor once drives the second impeller 10 to rotate twice.

[0041] This reduces power consumption and improves ventilation efficiency in industrial plants, thereby achieving energy conservation.

[0042] As shown in Figures 2, 3, and 6, the air inlet assembly 4 includes a fixed plate 401, which is fixedly installed on one side of the ventilation duct 1. An air inlet hole 402 is opened at an equal angle on the outer side of the fixed plate 401. A sliding groove 403 is opened inside the air inlet hole 402. A transmission ring 409 is threaded onto the outer side of the crank 7. A connecting ring 408 is movably sleeved on the outer side of the transmission ring 409. A connecting block 405 is fixedly installed on one side of the connecting ring 408. A spring 406 is fixedly installed on one side of the connecting block 405. A sealing plate 404 is hinged at an equal angle on the outer side of the connecting ring 408. Sliding blocks 407 are fixedly installed on the front and rear sides of the outer side of the sealing plate 404. A dustproof net 410 is fixedly installed on the outer side of the connecting block 405.

[0043] Using the above scheme: By starting the dual-shaft motor 6, the bolt 7 and the first impeller 9 are driven to rotate. During the rotation of the bolt 7, the resistance between the connecting ring 408 and the transmission ring 409 limits the transmission ring 409, causing the transmission ring 409, connecting ring 408, and connecting block 405 to move to the right, compressing the spring 406. As the connecting ring 408 moves to the right, it pulls the inner side of the sealing plate 404, causing the outer end of the sealing plate 404 to slide inside the air inlet 402, causing the outer part of the sealing plate 404 to converge towards the center of the air inlet 402, making the sealing plate 404 fan-shaped. At this time, the fixing plate 401 will open, and the transmission ring 409 will move to the rightmost end of the bolt 7. The spring 406 will be completely compressed, and the bolt 7 will continue to rotate. At this time, the transmission ring 409 will rotate with the bolt 7. When located at the far right end of the rocker arm 7, the air inlet 402 will be fully opened. The first impeller 9 will be rotated by the dual-shaft motor 6 to draw air from the outside and enter the ventilation duct 1 through the air inlet 402, thus ventilating the industrial plant. At the same time, the dustproof net 410 will block external dust and impurities, effectively preventing dust from entering the ventilation duct 1 and the interior of the plant.

[0044] As shown in Figures 2, 7, and 8, the adjusting assembly 8 includes a support ring 801, which is fixedly installed on the inner wall of the guide tube 3. An adjusting plate 802 is annularly hinged at an equal angle to one side of the support ring 801. An airbag 804 is fixedly installed on the inner wall of the guide tube 3, outside the adjusting plate 802. All seven adjusting plates 802 are fan-shaped, and the combined inner diameter of the seven adjusting plates 802 gradually decreases from left to right. The outer surfaces of the seven adjusting plates 802 are fixedly connected to the inner wall of the airbag 804. One side of the pushing plate 202 contacts the adjusting assembly 8.

[0045] One side of ring 803 is in contact with each other, and the gap between two adjacent support blocks 204 is connected to the dispersion port 203;

[0046] The exhaust assembly 2 includes an adjusting ring 201, which is threadedly connected to the guide pipe 3. A support block 204 is fixedly installed at an equal angle on one side of the inner side of the adjusting ring 201. A push plate 202 is fixedly installed on one side of the support block 204. A dispersion port 203 is opened at an equal angle on one side of the adjusting ring 201. An air inlet 205 is opened in the middle of one side of the adjusting ring 201.

[0047] The above scheme is adopted as follows: by rotating the adjusting ring 201, it moves to the left under the action of the external thread of the guide tube 3. During the movement, the pushing plate 202 pushes the contact ring 803 to the left and squeezes the airbag 804. When one side of the airbag 804 is under pressure, it will expand and squeeze one end of the adjusting plate 802 inward, making the adjusting plate 802 into a trumpet shape, and the inner diameter value gradually decreases from left to right. When the wind enters the inner side of the adjusting plate 802, the wind will gradually gather towards the inner side of the adjusting plate 802, thereby increasing the wind speed.

[0048] By rotating the adjusting ring 201 in the opposite direction, the adjusting ring 201 moves to the right under the action of the external thread of the guide pipe 3, and adjusts the push plate 202. At this time, the airbag 804 will gradually reset and drive the right end of the adjusting plate 802 to expand in all directions. The air inside the guide pipe 3 will enter the interior of the exhaust assembly 2 and then enter the interior of the two adjacent support blocks 204 respectively. It will then be dispersed and discharged through the dispersion port 203, thereby improving the heat dissipation effect in the industrial plant.

[0049] As shown in Figures 2, 3, and 6, the sealing plate 404 is movably engaged inside the air inlet 402, the sliding block 407 is movably engaged inside the sliding groove 403, the inner side of the sealing plate 404 is movably hinged to the outer side of the connecting ring 408, the outer side of the connecting block 405 is fixedly connected to the inner side of the dustproof net 410, the outer side of the dustproof net 410 is fixedly connected to the inner wall of the ventilation pipe 1, the connecting ring 408 is movably sleeved on the outer side of the transmission ring 409, the resistance value between the connecting ring 408 and the transmission ring 409 is 2f, one side of the spring 406 is fixedly installed on one side of the connecting block 405, and one side of the rocker arm 7 is movably installed on one side of the air inlet assembly 4.

[0050] The above solution involves using a dual-axis motor 6 to rotate the crankshaft 7. The resistance between the connecting ring 408 and the transmission ring 409 limits the movement of the transmission ring 409. During rotation, the transmission ring...

[0051] Ring 409 moves to the right along the outside of the rocker arm 7 and compresses the spring 406, while simultaneously moving the connecting ring 408 to the right. During this movement, the sealing plate 404 slides inside the air inlet 402. At the same time, the outer end of the sealing plate 404 gathers towards the center of the air inlet 402, thereby opening the air inlet 402. At this time, the external air can enter the interior of the industrial plant through the air inlet 402.

[0052] Working principle and usage process of this invention:

[0053] When ventilation is required in an industrial warehouse building, the adjusting ring 201 is rotated first. Under the action of the external thread of the guide pipe 3, the adjusting ring 201 moves to the left. During the movement, the pushing plate 202 pushes the contact ring 803 to the left and squeezes the air bag 804. When one side of the air bag 804 is under pressure, it will expand and squeeze one end of the adjusting plate 802 inward, making the adjusting plate 802 into a trumpet shape, and the inner diameter value gradually decreases from left to right. At the same time, the dispersing port 203 is sealed by one side of the guide pipe 3.

[0054] Then, by starting the dual-shaft motor 6, the bolt 7 and the first impeller 9 are driven to rotate. During the rotation of the bolt 7, the resistance between the connecting ring 408 and the transmission ring 409 limits the transmission ring 409, causing the transmission ring 409, connecting ring 408, and connecting block 405 to move to the right, compressing the spring 406. As the connecting ring 408 moves to the right, it pulls the inner side of the sealing plate 404, causing the outer end of the sealing plate 404 to slide inside the air inlet 402, causing the outer part of the sealing plate 404 to converge towards the center of the air inlet 402, making the sealing plate 404 fan-shaped. At this time, the fixing plate 401 will open, and the transmission ring 409 will move to the rightmost end of the bolt 7. The spring 406 will be fully compressed, and the bolt 7 will continue to rotate. At this time, the transmission ring 409 will rotate with the bolt 7. At the far right end, the air inlet 402 will be fully opened;

[0055] Simultaneously, the dual-shaft motor 6 drives the first impeller 9 to rotate, which in turn drives the first transmission plate 502 to rotate. During the rotation of the first transmission plate 502, the first magnets 503 are also driven to rotate. Since there are four first magnets 503 and eight second magnets 507, when the first transmission plate 502 rotates one revolution, the second transmission plate 506 will rotate two revolutions. The rotation of the second transmission plate 506 drives the second impeller 10 to rotate, and the high-speed rotation of the second impeller 10 draws air from the outside.

[0056] The air enters the ventilation duct 1 through the air inlet 402. At the same time, the dust filter 410 filters the external dust and impurities before entering the guide duct 3. Since the inner diameter of the guide duct 3 is smaller than that of the ventilation duct 1, the air will gather inside the guide duct 3 when it enters, thereby increasing the air velocity. The air velocity is further increased inside the regulating plate 802, and then discharged into the interior of the industrial plant through the air inlet 205, thus ventilating the industrial plant.

[0057] Simultaneously, when heat dissipation is required inside the factory, the adjusting ring 201 is rotated in the reverse direction.

[0058] 201 moves to the right under the action of the external thread of the guide tube 3 and adjusts the push plate 202. At this time, the airbag 804 will gradually reset and drive the right end of the adjustment plate 802 to unfold in all directions. The air inside the guide tube 3 will enter the interior of the exhaust assembly 2 and enter the interior of the two adjacent support blocks 204 respectively, and then enter the dispersion and discharge through the dispersion port 203.
