DETAILED DESCRIPTION

[0033] 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.

[0034] Example 1

[0035] This embodiment is intended to promote the solution of the problem that existing building energy-saving ventilation equipment is weak in utilizing natural wind or cannot utilize natural wind for ventilation, and cannot wipe the important internal structures, which easily accumulates dust and causes the equipment to fail to work properly; please refer to Figure 1-8 , a building energy-saving ventilation device, including a device body 1 located on the roof of a building, a ventilation component 2 for adjusting according to wind direction is installed in the device body 1, and the device can reduce energy consumption by automatically adjusting ventilation, especially when it is necessary to cool or heat the indoor space, reducing the cost of heating and cooling, the ventilation component 2 includes a support frame 201 fixedly installed inside the device body 1, one end of the support frame 201 is rotatably connected to a support rod 202, and an adjustable air guide plate 203 is fixedly connected to the support rod 202, the adjustable air guide plate 203 rotates under the cooperation of the support frame 201 and the support rod 202, and the adjustable air guide plate 203 is adjusted according to the wind force, so as to facilitate ventilation in the building;

[0036] Sliding tracks 204 are provided below both ends of the adjustable air guide plate 203, and a rain shielding component 3 is slidably connected to the sliding track 204. The rain shielding function can extend the service life of the equipment and reduce the maintenance and repair costs. By improving the ventilation and rain shielding functions, the equipment improves the indoor comfort, ensures the indoor air quality, and prevents rain from entering the room. The rain shielding component 3 includes a round rod 301 slidably connected to the sliding tracks 204 below both ends of the adjustable air guide plate 203, and the round rod 301 is rotatably connected to a cylinder 302, and the cylinder 302 A rain shield 303 for preventing rainwater from entering is fixedly connected to one side of the rain shield 303, a slide rail 304 is fixedly installed on the rain shield 303, a support rod 305 is slidably connected to the slide rail 304, and a telescopic plate 306 cooperating with the rain shield 303 to block rain is fixedly connected to the other end of the support rod 305, and the telescopic plate 306 blocks rainwater from the outside inside. The structure and coordinated work of the slide rail 304, the support rod 305 and the telescopic plate 306 ensure the smooth operation of the rain shield assembly 3, which reduces vibration and instability, and contributes to the stability and performance of the equipment;

[0037] The telescopic plate 306 is slidably connected to the outside with a telescopic bin 307. The design of the telescopic plate 306 and the telescopic bin 307 of the rain shield assembly 3 allows their lengths to be adjusted as needed to adapt to different usage conditions. The main function of the rain shield assembly 3 is to prevent rainwater from entering the interior of the ventilation equipment. The design of the rain shield 303 and the telescopic bin 307 and the coordinated work of the slide rail 304 and the support rod 305 ensure that rainwater cannot directly enter the interior of the equipment, thereby preventing the equipment from being damaged by rainwater. By effectively blocking rainwater, this component helps to maintain the internal environment of the ventilation equipment dry, which is very important for the normal operation and long-term reliability of the equipment, especially in humid climate conditions. Preventing rainwater from contacting internal parts of the equipment can reduce the risk of corrosion, which helps to extend the life of the equipment and reduce maintenance costs.

[0038] The rain shielding assembly 3 also includes a board storage bin 308 fixedly mounted inside the device body 1, and a rain shield 309 for assisting in rain protection is slidably connected inside the board storage bin 308, and a slope 3010 for fitting with the adjustable wind guide plate 203 is provided at one end of the rain shield 309, and the slope 3010 is provided at one end of the rain shield 309, and the slope 3010 can fit with the adjustable wind guide plate 203, so as to assist in adjusting the ventilation device under different wind directions, and the design of the rain shield 309 and the slope 3010 can provide additional protection for the ventilation device, ensuring that rainwater does not enter through other parts of the ventilation device, and this double protection helps to ensure that the inside of the device is always kept dry;

[0039] Below the rain shield 309, an elastic spring 3011 is fixedly installed inside the board storage bin 308 for restoring the rain shield 309 to its original position. The existence of the elastic spring 3011 allows the rain shield 309 to return to its original position for rain protection after adjustment. The fixed installation of the rain shield 309 and the design of the elastic spring 3011 not only help to restore the rain shield 309 to its original position, but also protect the rain shield 309 from the influence of the external environment. This structure provides additional functionality and protection for the ventilation equipment, ensuring that the equipment can operate efficiently in different weather conditions and provide proper ventilation when needed.

[0040] One end of the sliding track 204 is located inside the regulating air guide plate 203 and a pneumatic sealing assembly 4 is installed therein. The pneumatic sealing assembly 4 includes an extrusion plate 401, which is the core part of the sealing assembly. Pressure is transmitted through the extrusion plate 401. A force-bearing plate 402 is fixedly connected to one side of the extrusion plate 401. The force-bearing plate 402 is connected to the extrusion plate 401. When the extrusion plate 401 is squeezed, it will drive the force-bearing plate 402 to move together. A first airbag 403 is connected to one side of the force-bearing plate 402. A spring 404 for increasing the rebound force of the first airbag 403 is fixedly installed inside the first airbag 403. After the force-bearing plate 402 slides, pressure is applied to the first airbag 403 to cause the first airbag 403 to shrink and deform. The spring 404 installed in the first airbag 403 is used to increase the rebound force of the first airbag 403, which ensures that the extrusion plate 401 can return to its original state when the pneumatic force is canceled.

[0041] An outlet hole 405 for gas flow is provided on one side of the first airbag 403. After being squeezed, the first airbag 403 will discharge the internal gas from the outlet hole 405. A connecting pipe 406 for gas flow is fixedly connected to the outlet hole 405. One end of the connecting pipe 406 is fixedly connected to a gas delivery space 407. The connecting pipe 406 transfers the gas from the first airbag 403 to the gas delivery space 407. One side of the gas delivery space 407 is fixedly connected to an air blocking plate 408. A first circular hole 4013 for air intake is provided on the air blocking plate 408. The air blocking plate 408 is slidably connected to a fixed plate 409. A second circular hole 4014 cooperating with the first circular hole 4013 is provided on the fixed plate 409. One end of the air blocking plate 408 is designed as a soft layer to prevent gas loss. One end of the air blocking plate 408 is designed with a soft layer, which helps to prevent gas from losing through the edge of the air blocking plate 408 when in a sealed position.

[0042] The air blocking plate 408 is connected to the gas delivery space 407, which can provide additional obstacles during sealing to ensure that gas loss is minimized. By squeezing the plate 401 and the airbag, the pneumatic sealing assembly 4 achieves efficient sealing, prevents unnecessary gas flow, ensures airtightness, has a simple structure and clear functions, improves the reliability of the sealing assembly, reduces maintenance requirements, and extends service life.

[0043] The pneumatic sealing assembly 4 also includes a second airbag 4010 fixedly connected to the fixing plate 409 for auxiliary sealing. A sealing block 4011 for preventing rainwater from entering is fixedly installed at one end of the second airbag 4010. The sealing block 4011 on the second airbag 4010 ensures that the device is very effective in a sealed state, not only protecting the interior from dust, but also preventing rainwater from penetrating. The presence of the sealing block 4011 ensures that the interior of the device is dry, preventing rainwater, moisture or other liquids from entering, thereby extending the life of the device.

[0044] The second airbag 4010 is located on one side of the air blocking plate 408 and below the fixing plate 409, and is provided with an air inlet 4012 for gas to flow in. Combined with the first airbag 403, the air transmission space 407, the second airbag 4010, and the sealing block 4011, this structure provides comprehensive protection to ensure that the equipment can maintain sealing performance under various conditions; after the extrusion plate 401 is squeezed, it will drive the force plate 402 to slide, and during the sliding process, it will drive the first airbag 403 to shrink, and during the shrinkage process, the spring 404 will be deformed. After the first airbag 403 shrinks, the internal gas will be discharged into the connecting pipe 406 through the air outlet 405;

[0045] The connecting pipe 406 guides the gas into the gas delivery space 407. After the gas is taken in, the gas delivery space 407 will expand and contract. After the expansion and contraction, the first circular hole 4013 on the air blocking plate 408 and the second circular hole 4014 on the fixing plate 409 will be connected, thereby opening a channel for the gas to enter the second airbag 4010. The second airbag 4010 that has entered the gas will expand and contract. The expansion and contraction of the second airbag 4010 drives the sealing block 4011 to move, so that the interior is sealed to prevent rainwater from entering.

[0046] A wiping assembly 5 for wiping the rain shield assembly 3 is installed above the pneumatic sealing assembly 4. The wiping assembly 5 includes a third airbag 501 for auxiliary wiping connected to one side of the air delivery space 407. The third airbag 501 is a part of the wiping assembly 5 and is used to provide the mobile support required by the wiping block 502. The third airbag 501 is in communication with the air delivery space 407 so as to work together. One end of the third airbag 501 is fixedly connected to the wiping block 502. A soft convex strip 507 is provided below the wiping block 502. The soft convex strip 507 is used to prevent dust from adhering to the sealing block 4011. An arc portion 503 is cut at one end of the wiping block 502. The soft convex strip 507 on the wiping block 502 is a structure that actually performs the wiping operation. One end of the wiping block 502 is cut into an arc so that it can adapt to the curved surface of the rain shield assembly 3, thereby wiping the surface more closely.

[0047] An arc-shaped guide plate 504 for guiding the direction of the wiping block 502 is installed on one side of the wiping block 502. The arc-shaped guide plate 504 is fixedly installed inside the adjusting air guide plate 203. The arc-shaped guide plate 504 ensures that the soft convex strip 507 maintains stable movement during the wiping process, avoids unnecessary vibration and swing, and ensures that the wiping effect is uniform and efficient. Its function is to guide the movement of the wiping block 502 and ensure that the soft convex strip 507 maintains good contact with the rain shield component 3 during the wiping process, so as to achieve cleaner wiping. The inner side of the arc-shaped guide plate 504 is designed in an arc shape, and the arc 503 of the wiping block 502 is slidably connected to the inner side of the arc-shaped guide plate 504. The cutting arc of the wiping block 502 and the design of the arc-shaped guide plate 504 ensure the wiping of the rain shield component 3 to eliminate the accumulation of dust, dirt and water droplets. By wiping the internal structure of the rain shield component 3, the adhesion of dust can be reduced and the subsequent maintenance can be reduced.

[0048] The third airbag 501 is divided into a first corrugated plate 505 and a second corrugated plate 506 on both sides. The first corrugated plate 505 is extended to a longer length after the third airbag 501 is inflated, and the second corrugated plate 506 is extended to a shorter length after the third airbag 501 is inflated. The different length extensibility of the first corrugated plate 505 and the second corrugated plate 506 enables the third airbag 501 to complete the wiping action more accurately. This asymmetric design enables the third airbag 501 to better adapt to the outer contour of the structure that needs to be wiped. The third airbag 501 forms an arc after air is inflated. The shaped structure enables the wiping block 502 to better complete the wiping action. When the gas inside the first airbag 403 is squeezed into the air delivery space 407, the third airbag 501 will also expand and contract after the gas enters the air delivery space 407 because the third airbag 501 is connected to the air delivery space 407. During the expansion and contraction of the third airbag 501, the wiping block 502 is driven to move in an arc shape. In addition, the guidance of the arc-shaped guide plate 504 further stabilizes the wiping action of the wiping block 502. The structure and function of this building energy-saving ventilation equipment help to improve the energy efficiency, indoor environmental quality and comfort of the building, while reducing maintenance costs.

[0049] The top of the regulating air guide plate 203 is coated with a waterproof coating to prevent rainwater from hanging on it. The waterproof coating ensures the effective operation of the regulating air guide plate 203. Under humid conditions, rainwater may freeze or condense on the air guide plate, affecting its free movement. The waterproof coating can prevent this from happening and maintain the normal function of the equipment. The regulating air guide plate 203 coated with a waterproof coating helps to ensure that the equipment continues to operate efficiently under humid and rainy conditions, thereby improving the performance, reliability and durability of the equipment. This is very important for building energy-saving ventilation equipment, especially under severe weather conditions. When the regulating air guide plate 203 needs to be adjusted, the regulating air guide plate 203 will tilt, and the lifted end will cause the round rod 301 to drive the cylinder 302 to slide together in the sliding track 204 under the influence of gravity. The sliding of the cylinder 302 drives the rain shield 303 to slide together;

[0050] At the same time, the support rod 305 slidingly connected inside the rain shield 303 drives the telescopic plate 306 to slide on the slide rail 304. As the adjustable wind guide plate 203 continues to be lifted, the telescopic plate 306 will be slidably connected with the telescopic bin 307, and the pressed end will be opposite to it. At the same time, when the adjustable wind guide plate 203 is pressed down to a certain extent, the adjustable wind guide plate 203 will fit with the slope 3010 on the rain shield 309. When the adjustable wind guide plate 203 continues to be pressed down, the rain shield 309 will be retracted into the retracting bin 308. At the same time, the elastic spring 3011 will be deformed. When the adjustable wind guide plate 203 is lifted up, the rain shield 309 will return to its original position under the action of the elastic spring 3011.

[0051] An array of rectangular fixing holes 205 are provided on the support rod 202, and a raised round block 206 is slidably installed on the support frame 201. The raised round block 206 is slidably connected to the rectangular fixing hole 205. After the adjustment air guide plate 203 is adjusted to a suitable position, it is only necessary to slide the raised round block 206 into the rectangular fixing hole 205 to complete the fixation of the position of the adjustment air guide plate 203.

[0052] This embodiment also provides a method for using the building energy-saving ventilation equipment, comprising the following steps:

[0053] S1. Adjust the inclination angle of the wind guide plate 203 by rotating the support rod 202 according to the wind direction;

[0054] S2, during the rotation of the adjusting wind deflector 203, the rain shielding component 3 will be adapted to the corresponding position to shield the rain;

[0055] S3, the pneumatic sealing component 4 is squeezed during the sliding of the rain shield component 3, so that the gas flows out from the first airbag 403;

[0056] S4, after the gas flows out from the first airbag 403, the pneumatic sealing assembly 4 enters the working state;

[0057] S5, simultaneously, the wiping component 5 wipes the components in the rain shielding component 3;

[0058] S6. After adjusting the air guide plate 203, the angle on one side increases, which is beneficial for the entry of fresh air.

[0059] Working principle:

[0060] First, the inclination angle of the wind guide plate 203 is adjusted by rotating the support rod 202 according to the wind direction. The wind guide plate 203 will be tilted, and the lifted end will cause the round rod 301 to drive the cylinder 302 to slide in the sliding track 204 under the influence of gravity. The sliding of the cylinder 302 drives the rain shield 303 to slide together. At the same time, the support rod 305 slidably connected in the rain shield 303 drives the telescopic plate 306 to slide on the sliding rail 304. As the wind guide plate 203 continues to be lifted, the telescopic plate 306 will be slidably connected to the telescopic bin 307.

[0061] The pressed end is opposite to it. When the adjusted wind guide plate 203 is pressed down, the adjusted wind guide plate 203 will fit with the slope 3010 on the rain shield 309. When the adjusted wind guide plate 203 continues to be pressed down, the rain shield 309 will be retracted into the board storage bin 308. At the same time, the elastic spring 3011 will be deformed. When the adjusted wind guide plate 203 is lifted up, the rain shield 309 will return to its original position under the action of the elastic spring 3011.

[0062] At this time, the cylinder 302 will squeeze the extrusion plate 401 through the gravity of the downward movement. After being squeezed, the extrusion plate 401 will drive the force-bearing plate 402 to slide, and the first airbag 403 will be driven to shrink during the sliding process, and the spring 404 will be deformed during the shrinking process. After the first airbag 403 shrinks, the internal gas will be discharged into the connecting pipe 406 through the air outlet 405. The connecting pipe 406 guides the gas into the gas transmission space 407. The gas transmission space 407 will expand and contract after the air is taken in. After the expansion and contraction, the first circular hole 4013 on the air blocking plate 408 and the second circular hole 4014 on the fixed plate 409 will be connected, thereby opening a channel for the gas to enter the second airbag 4010. The second airbag 4010 that enters the gas will expand and contract. The expansion and contraction of the second airbag 4010 drives the sealing block 4011 to move, thereby achieving a seal to prevent rainwater from entering important structures.

[0063] At the same time, since the third airbag 501 is connected to the gas transmission space 407, the third airbag 501 will also expand and contract after the gas enters. During the expansion and contraction of the third airbag 501, the wiping block 502 is driven to move in an arc shape. In addition, under the guidance of the arc guide plate 504, the wiping block 502 drives the soft convex strip 507 to wipe the surface of the cylinder 302. After adjusting the position of the air guide plate 203, the raised round block 206 is slidably inserted into the rectangular fixing hole 205 to complete the fixation.

[0064] When the wind guide plate 203 is adjusted to return to its original position, the first airbag 403, under the action of the spring 404, causes the force plate 402 and the extrusion plate 401 to push the cylinder 302 back to its original position. At the same time, as the first airbag 403 expands and contracts, the gas in the other airbags returns to the first airbag 403.
