Description

Technical Field

[0001] The utility model relates to the technical field of energy-saving equipment, in particular to ventilation energy-saving equipment for buildings. Background Art

[0002] Green buildings save resources, protect the environment, reduce pollution, provide people with healthy, applicable and efficient use space, and maximize the high-quality buildings that realize harmonious coexistence between man and nature. Construction waste is inevitable during construction. Construction waste refers to the slag, abandoned soil, abandoned materials, silt and other wastes generated during the construction, laying, demolition and repair of various buildings, structures, pipe networks, etc. by construction units or individuals. When constructing green buildings, due to the ventilation needs of the building, a ventilation system must be set up inside the building. At the same time, in order to ensure the energy saving of green buildings, it is crucial to recycle the energy of ventilation equipment, especially the exhaust equipment installed on the top of the building.

[0003] A Chinese utility model patent with publication number CN216953358U discloses a ventilation energy-saving device for a building, including a building, a ventilation device fixedly installed on one side of the building, a cleaning device fixedly installed on one side of the building, the ventilation device including a ventilation channel, a ventilation fan, a dustproof screen and a fixing mechanism, a ventilation fan is arranged inside the ventilation channel, and a dustproof screen is movably connected to one side of the ventilation channel.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the above-mentioned device cleans the dustproof mesh plate by means of a cleaning brush that slides up and down. However, in actual practice, when the cleaning brush cleans the dustproof mesh plate, some of the bristles of the cleaning brush are prone to extend into the mesh holes of the dustproof mesh plate, which may easily cause some dust to move to the other side of the dustproof mesh plate, thereby easily causing the dust moved to the other side of the dustproof mesh plate to enter the building when the staff turns on the ventilation device, which is not conducive to improving the staff's user experience. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a ventilation energy-saving device for a building.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a ventilation and energy-saving equipment for a building, including a building main body and a ventilation device installed on the building main body, a ventilation hole is opened on the side wall of the building main body, the ventilation device is connected to the inner wall of the ventilation hole, an annular plate facing the ventilation hole is arranged on the side wall of the building main body, a dustproof net for blocking dust is arranged on the inner wall of the annular plate, a cleaning component for cleaning the dustproof net is arranged on the side wall of the annular plate, and a blocking component for closing the annular plate is arranged on the annular plate.

[0007] By adopting the above technical solution, when the staff needs to ventilate the building, the staff only needs to turn on the ventilation device to allow the ventilation device to inject fresh air into the building, and the dust net can block dust and other impurities in the fresh air. After the dust net has been used for a period of time, the staff only needs to start the blocking component and the cleaning component in turn to close the annular plate, and let the cleaning component clean the dust net, so that the blocking component can collect the impurities that pass through the dust net during the cleaning process of the staff, thereby reducing the probability of impurities that pass through the dust net during the cleaning process of the dust net entering the main body of the building, thereby improving the staff's use experience.

[0008] Furthermore, a sliding groove is opened on the inner wall of the annular plate, and the cleaning assembly includes a sliding rod slidably arranged in the sliding groove, a cleaning brush arranged on the side wall of the sliding rod, a driving motor arranged on the upper surface of the annular plate, and a threaded rod fixed to the end of the output shaft of the driving motor, the threaded rod passes through the sliding rod and is threadedly connected, and the output shaft of the driving motor extends into the sliding groove.

[0009] By adopting the above technical solution, when the staff needs to clean the dust net, the staff only needs to start the barrier component and start the drive motor to rotate the output shaft of the drive motor, so that the threaded rod rotates with the output shaft of the drive motor, and then the sliding rod and the cleaning brush move up and down under the action of the threaded rod, so that the cleaning brush cleans the dust net.

[0010] Furthermore, a sliding groove is provided on the inner wall of the annular plate, a rotating groove is provided on the inner top wall of the annular plate, a rotating hole is provided on the inner wall of the rotating groove, and a receiving groove is provided on the inner bottom wall of the annular plate. The blocking assembly includes a rotating rod rotatably arranged in the rotating hole, a sliding block slidably arranged in the sliding groove, a blocking cloth fixed at one end to the rotating rod, a torsion spring fixed at one end to the rotating rod, and a storage box arranged in the receiving groove, the other end of the blocking cloth is fixed to the sliding block, and the other end of the torsion spring is fixed to the inner wall of the rotating hole.

[0011] By adopting the above technical solution, when the staff needs to clean the dust net, the staff needs to close the annular plate. At this time, the staff needs to slide the sliding block and open the storage box so that the barrier cloth can move downward with the sliding block. When the sliding block moves to the lowest point, the bottom surface of the barrier cloth is flush with the inner bottom wall of the annular plate, so that the barrier cloth closes the annular plate. At this time, the staff only needs to start the cleaning component to make the cleaning component clean the dust net. In this process, some impurities easily pass over the dust net and fall into the storage box, so that the storage box collects the impurities that pass over the dust net during the cleaning process, thereby reducing the probability of impurities entering the building.

[0012] Furthermore, a connecting rope is connected to the bottom surface of the barrier cloth, and the other end of the connecting rope extends outside the annular plate and is slidably connected.

[0013] By adopting the above technical solution, when the staff needs to slide the sliding block downward, the staff only needs to pull the connecting rope to make the barrier cloth and the sliding block move downward following the connecting rope.

[0014] Furthermore, an iron block is arranged on the bottom surface of the sliding block, a receiving hole is opened on the inner bottom wall of the sliding groove, an electromagnet is arranged on the inner bottom wall of the receiving hole, and the electromagnet is connected in series with the driving motor.

[0015] By adopting the above technical solution, when the staff starts the drive motor, the electromagnet is energized because the electromagnet and the drive motor are connected in series. Then, when the staff slides the sliding block, the iron block moves with the sliding block. When the sliding block moves to the lowest point, the iron block and the electromagnet contact each other, and the electromagnet adsorbs the iron block, thereby keeping the sliding block stable. There is no need for the staff to continuously apply force to the connecting rope to keep it stable, thereby reducing the difficulty of operation for the staff. Then, when the dust net is cleaned, the staff only needs to turn off the power to the electromagnet to reset the sliding block under the action of the torsion spring.

[0016] Furthermore, the storage box includes a placement box arranged on the inner bottom wall of the receiving groove and a partition plate slidably arranged on the inner wall of the placement box, and a placement hole matching the partition plate is opened through the inner wall of the receiving groove.

[0017] Furthermore, a plumb block is connected to the lower end of the connecting rope for improving the stability of the connecting rope.

[0018] Furthermore, an inclined surface is provided at the lower end of the side wall of the annular plate away from the building body.

[0019] By adopting the above technical solution, when the cleaning brush cleans the dustproof net, impurities close to the cleaning brush fall downward and contact the inclined surface, thereby increasing the probability of the impurities continuing to move downward and reducing the probability of impurities accumulating in the annular plate.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In this application, when the staff needs to ventilate the building, the staff only needs to turn on the ventilation device to allow the ventilation device to inject fresh air into the building, and the dust net can block dust and other impurities in the fresh air. After the dust net has been used for a period of time, the staff only needs to start the blocking component and the cleaning component in turn to close the annular plate, and let the cleaning component clean the dust net, so that the blocking component can collect the impurities that pass through the dust net during the cleaning process of the staff, thereby reducing the probability of impurities that pass through the dust net during the cleaning process of the dust net entering the main body of the building, thereby improving the staff's user experience;

[0022] 2. In this application, when the staff needs to clean the dust net, the staff only needs to start the blocking component and start the driving motor to rotate the output shaft of the driving motor, so that the threaded rod rotates with the output shaft of the driving motor, and then the sliding rod and the cleaning brush move up and down under the action of the threaded rod, so that the cleaning brush cleans the dust net;

[0023] 3. In this application, when the staff needs to clean the dust net, the staff needs to close the annular plate. At this time, the staff needs to slide the sliding block and open the storage box so that the barrier cloth can move downward with the sliding block. When the sliding block moves to the lowest point, the bottom surface of the barrier cloth is flush with the inner bottom wall of the annular plate, so that the barrier cloth closes the annular plate. At this time, the staff only needs to start the cleaning component to make the cleaning component clean the dust net. In this process, some impurities easily pass over the dust net and fall into the storage box, so that the storage box collects the impurities that pass over the dust net during the cleaning process, thereby reducing the probability of impurities entering the building.

The threaded rod 44 is fixed to the end of the output shaft of the drive motor 43, and the threaded rod 44 passes through the slide bar 41 and is threadedly connected.

[0035] When the staff needs to clean the dust net 3, the staff only needs to start the blocking component 5 and start the driving motor 43 to rotate the output shaft of the driving motor 43, so that the threaded rod 44 rotates with the output shaft of the driving motor 43, and then the sliding rod 41 and the cleaning brush 42 move up and down under the action of the threaded rod 44, so that the cleaning brush 42 cleans the dust net 3.

[0036] A sliding groove 45 is provided on the inner wall of the annular plate 21, a rotating groove 46 is provided on the inner top wall of the annular plate 21, a rotating hole 47 is provided on the inner wall of the rotating groove 46, and a receiving groove 48 is provided on the inner bottom wall of the annular plate 21.

The sliding block 52 is a rectangular block-shaped structure, and the sliding block 52 is slidably arranged in the sliding groove 45. One end of the blocking cloth 53 is fixed to the rotating rod 51, and the other end of the blocking cloth 53 is fixed to the sliding block 52. One end of the torsion spring 54 is fixed to the rotating rod 51, and the other end of the torsion spring 54 is fixed to the inner wall of the rotating hole 47.

[0037] When the staff needs to clean the dust net 3, the staff needs to close the annular plate 21. At this time, the staff needs to slide the sliding block 52 and open the storage box 55, so that the barrier cloth 53 can move downward with the sliding block 52. When the sliding block 52 moves to the lowest point, the bottom surface of the barrier cloth 53 is flush with the inner bottom wall of the annular plate 21, so that the barrier cloth 53 closes the annular plate 21. At this time, the staff only needs to start the cleaning component 4 to make the cleaning component 4 clean the dust net 3. In this process, some impurities easily pass over the dust net 3 and fall into the storage box 55, so that the storage box 55 collects the impurities that pass over the dust net 3 during the cleaning process, thereby reducing the probability of impurities entering the building.

[0038] The storage box 55 is arranged in the receiving groove 48, and the storage box 55 includes a placement box 551 and a partition 552.

When the staff needs to slide the sliding block 52 downward, the staff only needs to pull the connecting rope 6 to make the barrier cloth 53 and the sliding block 52 move downward following the connecting rope 6.

[0040] The iron block 61 is a block structure and is disposed on the bottom surface of the sliding block 52. An accommodating hole 62 is provided on the inner bottom wall of the sliding groove 45, and the electromagnet 7 is disposed on the inner bottom wall of the accommodating hole 62, and the electromagnet 7 and the driving motor 43 are connected in series.

[0041] When the staff starts the drive motor 43, the electromagnet 7 is energized because the electromagnet 7 is connected in series with the drive motor 43. Subsequently, when the staff slides the sliding block 52, the iron block 61 moves with the sliding block 52. When the sliding block 52 moves to the lowest point, the iron block 61 contacts the electromagnet 7, and the electromagnet 7 adsorbs the iron block 61, thereby keeping the sliding block 52 stable. There is no need for the staff to continuously apply a force to the connecting rope 6 to keep it stable, thereby reducing the difficulty of the staff's operation. Subsequently, when the dustproof net 3 is cleaned, the staff only needs to turn off the power to the electromagnet 7 to reset the sliding block 52 under the action of the torsion spring 54.

[0042] In order to improve the stability of the connecting rope 6 , a plumb block 8 is connected to the lower end of the connecting rope 6 .

[0043] In order to reduce the probability of impurities accumulating in the annular plate 21, an inclined surface is provided at the lower end of the side wall of the annular plate 21 away from the building body 1.

[0044] The use principle of a ventilation energy-saving device for a building in this embodiment is as follows: when the staff needs to ventilate the building, the staff only needs to turn on the ventilation device 11, so that the ventilation device 11 can inject fresh air into the building, and the dustproof net 3 can block dust and other impurities in the fresh air. After the dustproof net 3 has been used for a period of time, the staff only needs to start the blocking component 5 and the cleaning component 4 in turn to close the annular plate 21, and let the cleaning component 4 clean the dustproof net 3, so that the blocking component 5 can collect the impurities that pass through the dustproof net 3 during the cleaning process of the staff, thereby reducing the probability of impurities that pass through the dustproof net 3 during the cleaning process of the dustproof net 3 entering the building body 1, thereby improving the staff's use experience.
