[0002] Civil defense engineering refers to underground protective buildings constructed separately to ensure the shelter of personnel and materials, command of civil air defense, and medical rescue during wartime, as well as basements that can be used for air defense during wartime and are built in conjunction with above-ground buildings.

[0003] In the existing technology, it has been found that although the dirt collection box can be pulled out for treatment during actual use, the coarse filter layer and activated carbon filter layer in the device are difficult to disassemble and clean. After long-term use, the filter device without cleaning is prone to reducing the filtration effect. At the same time, fixing and disassembling with fixing bolts is not conducive to improving work efficiency. Therefore, it is necessary to improve the ventilation and filtration device for civil defense projects to solve the above problems. Utility Model Content

[0028] The filter collection mechanism 6 includes a filter component 61 and a collection component 62. The filter component 61 is disposed inside the ventilation duct 1, and the collection component 62 is disposed inside the dust collection box 4.

[0029] Furthermore, the filter assembly 61 includes a filter plate 611, which is fixedly connected inside the ventilation duct 1. A guide rail 612 is fixedly connected to the right side of the filter plate 611. A limit plate 618 is slidably connected inside the guide rail 612. A scraper 615 is fixedly connected to the left side of the limit plate 618. A contact plate 616 is fixedly connected to the bottom of the scraper 615. A support frame 613 is fixedly connected inside the ventilation duct 1. An impeller 614 is rotatably connected inside the support frame 613. A connecting rod 617 is fixedly connected to the left side of the impeller 614, which facilitates the simultaneous filtration of the filter plate 611 and the scraping off of larger impurities adhering to the filter plate 611.

[0030] Furthermore, the limiting plate 618 and the connecting rod 617 are respectively provided with grooves, and the connecting rod 617 is movably connected inside the groove. The scraper 615 and the filter plate 611 are slidably connected, which makes the filtration process more stable.

[0031] Furthermore, the collection component 62 includes a rotating plate 621, which is rotatably connected inside the ventilation duct 1. A first fixing block 622 is fixedly connected to the bottom of the rotating plate 621, and a second fixing block 623 is fixedly connected inside the dust collection box 4. A first rotating block 624 is rotatably connected inside the second fixing block 623. A gas strut 625 is fixedly connected to the top of the first rotating block 624, and a second rotating block 626 is fixedly connected to the top of the gas strut 625. This facilitates the collection of scraped impurities while ensuring the airtightness of the ventilation duct 1.

[0032] Furthermore, grooves are provided at corresponding positions of the first fixed block 622 and the second rotating block 626, and the second rotating block 626 is rotatably connected inside the groove. The contact plate 616 contacts the rotating plate 621, which facilitates a more stable collection process. Example

[0033] Based on Example 1, please refer to Figure 6-7 Furthermore, in conjunction with Embodiment 1, the auxiliary installation mechanism 7 includes a connecting platform 71, which is fixedly connected to the outside of the ventilation duct 1. A bidirectional threaded rod 74 is rotatably connected inside the connecting platform 71. A limiting rod 75 is fixedly connected inside the connecting platform 71. An installation plate 72 is slidably connected to the outside of the limiting rod 75. A bellows baffle 73 is fixedly connected to the outside of the installation plate 72, which facilitates the adjustment of the position of the installation plate 72 and limits its movement, thereby satisfying the adjustment of the reserved hole positions and the pre-embedded ground nail positions in different installation environments.

[0034] Furthermore, the mounting plate 72 is threadedly connected to the bidirectional threaded rod 74, and the connecting platform 71 has a groove at the corresponding position of the mounting plate 72, and the mounting plate 72 is slidably connected inside the groove, which facilitates a more stable installation process.

[0035] In actual operation, when this device is used, the threaded rod is a T-type threaded rod to provide self-locking. After the operator moves the device to the designated installation location in the civil defense project, adjustments are made according to the reserved hole positions and pre-embedded ground nail positions in the installation environment. The operator uses tools such as a hex wrench to rotate the bidirectional threaded rod 74. The rotation of the bidirectional threaded rod 74, in conjunction with the limit rod 75, causes the mounting plate 72 to move. With the help of installation bolts and nuts, the mounting plate 72 is installed and limited to the designated installation position in the civil defense project. The ventilation fan 2 then starts to operate, and the air is filtered by the filter plate 611 and activated carbon plate 5. The impeller is driven by the set airflow. 614 rotates inside the support frame 613. The rotation of the impeller 614 causes the connecting rod 617 to rotate, which in turn causes the limiting plate 618 to slide up and down inside the guide rail 612. This causes the scraper 615 to move up and down, and the contact plate 616 to move. This satisfies the requirement of filtering the incoming air while scraping and cleaning the filter plate 611. The movement of the contact plate 616 causes the rotating plate 621 to rotate inside the ventilation duct 1. The rotation of the rotating plate 621, in conjunction with the first fixed block 622, causes the second rotating block 626 to move. In conjunction with the gas strut 625, the first rotating block 624 rotates inside the second fixed block 623. This, in conjunction with the dust collection box inside the dust collection box 4, collects the scraped impurities.
