Description

Technical Field

[0001] The utility model relates to the technical field of ventilation, in particular to an energy-saving ventilation device for construction. Background Technique

[0002] After the decoration of a new house is completed, the interior of the room is often filled with harmful gases such as formaldehyde and unpleasant odors, which pose a potential threat to the health of the occupants. Therefore, effective ventilation measures are urgently needed to accelerate the dissipation of harmful substances indoors. However, the currently commonly used method of opening windows for ventilation is simple and easy to implement, but it has significant drawbacks: its ventilation efficiency is low, and the dust and impurities mixed in the outside air are easily brought into the room during ventilation. In the long run, not only does it not completely improve the air quality, but it may also exacerbate the pollution of the indoor environment, resulting in dust accumulation and affecting the living comfort and health.

[0003] A kind of indoor ventilation mechanism for building construction recorded in the patent document with the patent publication number CN217178794U sucks the outside air into the room through an air pump, so that the indoor air can be quickly exchanged. Then, the incoming air is filtered through a filter screen to prevent the impurities contained therein from entering the room and polluting the indoor environment. The filter screen can be conveniently disassembled and assembled through an arc plate, a clamping plate and a clamping groove, and thus the filter screen can be conveniently replaced or cleaned.

[0004] However, every time the filter screen is replaced or cleaned in the above mechanism, it is necessary to disassemble components such as the arc plate and the clamping plate. This process is relatively cumbersome and time-consuming, resulting in the temporary interruption of the ventilation function during disassembly and assembly, and reducing the overall ventilation efficiency.

Detailed implementation mode

[0032] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] In one embodiment, as Figures 1 - 8 shown, an energy-saving ventilation and air change device for construction includes a base 11, an installation plate 20 is installed at the upper end of the base 11, an air outlet pipe 22 is installed at the upper end of the installation plate 20, installation side plates 21 are installed at both the left and right ends of the air outlet pipe 22, the installation side plates 21 are fixedly connected to the installation plate 20, the front end of the air outlet pipe 22 is fixedly connected to a filter pipe 31 through a flange, and the front end of the filter pipe 31 is fixedly connected to an air inlet pipe 46 through a flange;

[0034] A motor 23 is installed inside the air outlet pipe 22, and the output end of the motor 23 is fixedly connected to a fan 24;

[0035] It further includes a filtering structure, which is arranged inside the filter pipe 31 and is used for filtering the air entering the room;

[0036] A cleaning structure, which is arranged on the surface of the filtering structure and is fixedly connected to the fan 24, is used for cleaning the impurities on the surface of the filtering structure.

[0037] In this embodiment, when the device is started, the motor 23 starts to operate, and the output end of the motor 23 drives the fan 24 to rotate. The rotation of the fan 24 generates an air flow inside the air outlet pipe 22. At this time, the outside air enters the filter pipe 31 from the air inlet pipe 46.

[0038] In the filter pipe 31, the filtering structure plays a role. The filtering structure filters the incoming air, removes pollutants such as impurities and dust in the air, and enables the filtered clean air to continue to flow backward.

[0039] As the fan 24 continues to rotate, the cleaning structure also starts to work. Since the cleaning structure is fixedly connected to the fan 24, when the fan 24 rotates, the cleaning structure moves on the surface of the filtering structure, cleaning the impurities accumulated on the surface of the filtering structure during the filtering process, preventing excessive impurities from blocking the filtering structure, and ensuring the filtering effect of the filtering structure and the normal operation of the ventilation device. Finally, the filtered clean air is discharged from the air outlet pipe 22 and enters the room, realizing the energy-saving ventilation of the construction environment.

[0040] In one embodiment, as Figure 6 and Figure 7 shown, the filtering structure includes an installation groove 34, which is opened at the left and right ends of the filter pipe 31 and extends into the interior of the filter pipe 31. A first filter plate 35 and a second filter plate 36 are slidably installed inside the installation groove 34. A positioning hole 37 is opened at one end of the second filter plate 36 close to the first filter plate 35. A positioning rod 38 matching the positioning hole 37 is fixedly installed at one end of the first filter plate 35 close to the second filter plate 36. A fixed half-ring 39 is installed at the middle position of the opposite ends of the first filter plate 35 and the second filter plate 36. Locking components for locking the first filter plate 35 and the second filter plate 36 are provided at the left and right ends of the filter pipe 31.

[0041] The installation groove 34 provides an installation position for the first filter plate 35 and the second filter plate 36. The two can be slidably installed in the installation groove 34, which is convenient for installation and disassembly. The first filter plate 35 and the second filter plate 36 cooperate with each other to filter the air entering the filter pipe 31, improve the filtering effect, and remove pollutants such as impurities and dust in the air. The cooperation between the positioning rod 38 and the positioning hole 37 ensures that the first filter plate 35 and the second filter plate 36 can be accurately aligned during installation, improving the stability of filtering.

[0042] In one embodiment, as Figure 6 shown, the locking component includes a fixed lock block 32 and a lock plate 40. The fixed lock block 32 is fixedly installed at the left and right ends of the filter pipe 31. The fixed lock block 32 is provided with a lock hole 33. The lock plate 40 is fixedly installed at the far ends of the first filter plate 35 and the second filter plate 36. A spring groove 41 is opened inside the lock plate 40. A limiting plate 43 is slidably installed inside the spring groove 41. The limiting plate 43 is fixedly connected to one end of a return spring 42, and the other end of the return spring 42 is fixedly connected to the inner wall of the spring groove 41. The limiting plate 43 is fixedly connected to a lock rod 44. The lock rod 44 slidably penetrates the lock plate 40. The lock rod 44 matches the lock hole 33. A pull handle 45 is fixedly connected to the rear end of the lock rod 44.

[0043] The fixed lock block 32 cooperates with the lock plate 40, and the first filter plate 35 and the second filter plate 36 are locked by inserting the lock rod 44 into the lock hole 33. The reset spring 42 and the limit plate 43 are used to provide a certain elastic pressure during locking to ensure that the lock rod 44 is stably inserted into the lock hole and prevent the filter plate from loosening. The pull handle 45 facilitates the unlocking operation by the operator and is convenient for replacing or maintaining the filter plate.

[0044] In one embodiment, as Figure 5 shown, the cleaning structure includes a fixed rod 30 disposed inside the filter tube 31. The outer wall of the fixed rod 30 is rotatably connected to the inner wall of the fixed semi-ring 39. Cleaning plates 29 are fixedly installed on the outer walls at both ends of the fixed rod 30, and a connection component connected to the fan 24 is fixedly installed at the rear end of the cleaning plate 29.

[0045] When the fan 24 rotates, the cleaning plate 29 rotates on the surface of the filter plate along with the fixed rod 30 to clean the impurities accumulated on the filter plate during the filtering process, prevent excessive impurities from blocking the filter plate, and ensure the filtering effect and the normal operation of the ventilation and air exchange device.

[0046] In one embodiment, as Figure 5 shown, the connection component includes a connecting rod 25 and a long rod 28. The connecting rod 25 is fixedly installed at the front end of the fan 24, the long rod 28 is fixedly installed at the rear end of the cleaning plate 29. Fixed blocks 26 and square blocks 27 are respectively fixedly installed at the opposite ends of the connecting rod 25 and the long rod 28. A square groove matching the square block 27 is formed at one end of the fixed block 26 close to the square block 27, and threaded holes are formed in both the fixed block 26 and the square block 27, and the two threaded holes are corresponding in position.

[0047] The connecting rod 25 is fixed at the front end of the fan 24, and the long rod 28 is fixed at the rear end of the cleaning plate 29. Through the cooperation of the square groove on the fixed block 26 and the square block 27, and then the two threaded holes are threadedly connected by bolts, so as to realize the connection between the fan 24 and the cleaning plate 29. When the fan 24 rotates, it can drive the cleaning plate 29 to perform the cleaning work and ensure the cleaning effect of the filtering structure.

[0048] In one embodiment, as Figure 1 and Figure 2 shown, the base 11 and the mounting plate 20 are fixedly connected by a plurality of damping springs 18, and a damper 19 is installed inside each damping spring 18.

[0049] The setting of the damping springs 18 and the dampers 19 can reduce the vibration generated during the operation of the ventilation and air exchange device, improve the stability and reliability of the device. At the same time, it can also reduce the noise generated during the operation of the device and improve the construction environment.

[0050] In one embodiment, asFigure 8 As shown, a push rod 12 is fixedly installed at the rear end of the base 11, and a rotating column 13 is rotatably installed at the corner of the bottom end of the base 11. The bottom end of the rotating column 13 is fixedly connected to a wheel cover 14, and a roller 15 is rotatably connected inside the wheel cover 14.

[0051] The push rod 12 facilitates the operator to push the ventilation and air exchange device to move, improving the flexibility and convenience of the device. The rotating column 13 enables the wheel cover 14 to rotate flexibly, facilitating the adjustment of the moving direction of the device. The roller 15 enables the device to move easily on the construction site, meeting the requirements of different construction positions.

[0052] In one embodiment, as Figure 8 shown, an electric push rod 16 is installed at the upper end of the wheel cover 14, and the telescopic end of the electric push rod 16 extends into the wheel cover 14 and is fixedly connected to a friction block 17.

[0053] The electric push rod 16 can control the lifting of the friction block 17. When it is necessary to fix the device, the electric push rod 16 extends, making the friction block 17 contact the ground, increasing the friction force, preventing the device from moving during operation, and improving the stability of the device.

[0054] The above embodiment discloses an energy-saving ventilation and air exchange device for construction. Among them, starting the device: the motor 23 starts to operate, and the output end of the motor 23 drives the fan 24 to rotate. The rotation of the fan 24 generates an air flow in the air outlet pipe 22.

[0055] Air enters the filter pipe: At this time, the outside air enters the filter pipe 31 from the air inlet pipe 46.

[0056] The filtering structure plays a role:

[0057] The installation groove 34 provides installation positions for the first filter plate 35 and the second filter plate 36, and both can be slidably installed in the installation groove 34. The positioning rod 38 cooperates with the positioning hole 37 to ensure that the first filter plate 35 and the second filter plate 36 are accurately aligned. The first filter plate 35 and the second filter plate 36 cooperate with each other to filter the incoming air, removing pollutants such as impurities and dust in the air.

[0058] The fixed lock block 32 and the lock plate 40 cooperate, and the lock rod 44 is inserted into the lock hole 33 to lock the first filter plate 35 and the second filter plate 36. The return spring 42 and the limit plate 43 provide elastic pressure during locking to ensure that the lock rod 44 is stably inserted into the lock hole, preventing the filter plate from loosening. The pull handle 45 facilitates the operator to perform the unlocking operation, facilitating the replacement or maintenance of the filter plate.

[0059] The cleaning structure works:

[0060] The connecting rod 25 is fixed to the front end of the fan 24, and the long rod 28 is fixed to the rear end of the cleaning plate 29. Through the cooperation of the square groove on the fixing block 26 and the square block 27, the connection between the fan 24 and the cleaning plate 29 is realized. When the fan 24 rotates, it drives the cleaning plate 29 to rotate on the surface of the filter plate along the fixed rod 30, cleaning the impurities accumulated on the filter plate during the filtering process, preventing excessive impurities from blocking the filter plate, and ensuring the filtering effect and the normal operation of the ventilation device.

[0061] Air discharge: Finally, the filtered clean air is discharged from the air outlet pipe 22 and enters the room, realizing the energy-saving ventilation and air change in the construction environment.

[0062] Vibration and noise reduction: The base 11 and the mounting plate 20 are fixedly connected through a number of damping springs 18, and a damper 19 is installed inside each damping spring 18. The settings of the damping springs 18 and the dampers 19 can reduce the vibration generated during the operation of the ventilation device, improve the stability and reliability of the device, and at the same time reduce the noise generated during the operation of the device, improving the construction environment.

[0063] Moving and fixing device:

[0064] The push rod 12 facilitates the operator to push the ventilation device for movement, improving the flexibility and convenience of the device. The rotating column 13 enables the wheel cover 14 to rotate flexibly, facilitating the adjustment of the moving direction of the device. The rollers 15 enable the device to move easily on the construction site, adapting to the requirements of different construction positions.

[0065] The electric push rod 16 can control the lifting of the friction block 17. When the device needs to be fixed, the electric push rod 16 extends, making the friction block 17 contact the ground, increasing the friction force, preventing the device from moving during operation, and improving the stability of the device.

[0066] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application.
