Description

Technical Field

[0001] This utility model relates to the field of roof ventilation technology, and more specifically, it relates to a side-opening and closing dustproof device. Background Technology

[0002] In recent years, with the continuous development of industrial intelligence, the introduction of precision machining into traditional manufacturing has accelerated year by year. Leading enterprises in various industries have entered the era of intelligent digitalization. In particular, unmanned factories and "lights-out" factories are constantly emerging in the home appliance, electronics, and automotive industries, playing a positive role in promoting and leading modernization. These factories contain millions of precision instruments, placing higher demands on the air quality in factory workshops. Whether it's willow catkins in spring or dry dust in autumn, they can easily enter indoor spaces through skylights, leading to decreased sensor sensitivity. There have even been cases of fires caused by willow catkins, causing significant problems. Some dust prevention devices specifically designed for ventilators have appeared on the market, but these devices are mostly installed horizontally, offering poor protection and easily allowing rain and snow to drift in, causing considerable losses to enterprises. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a side-opening and closing dustproof device to solve one or more of the above-mentioned problems.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A side-opening and closing dustproof device is installed between adjacent vents on a roof or ventilator. It includes a boss mechanism fixedly installed on the roof or ventilator. Each boss mechanism has a filter element mechanism symmetrically hinged to both sides. Each filter element mechanism has a separate transmission mechanism. A power mechanism is installed on the roof, which is connected to all the transmission mechanisms. The power mechanism drives all the filter element mechanisms to rotate simultaneously relative to the boss mechanism through the transmission mechanisms. The rotated filter element mechanism seals the corresponding vent.

[0005] Furthermore, the boss mechanism is formed by two boss side panels, two boss vertical panels, and a boss light-transmitting and rain-shielding plate. The boss mechanism is provided with hinges on both sides, and the hinge height is level with the lowest point of the edge of the boss light-transmitting and rain-shielding plate.

[0006] Furthermore, the two ends of the raised platform for lighting and rain protection are symmetrically provided with an integrated rain protection plate pressure plate and a rain protection plate bracket, and the rain protection plate pressure plate and the rain protection plate bracket are located above the hinge.

[0007] Furthermore, the filter element mechanism includes a filter frame, the filter frame is filled with filter elements, and a filter element pressure plate is installed at the end of the filter frame.

[0008] Furthermore, the transmission mechanism includes a hollow column fixedly disposed inside the boss mechanism, a slider that slides up and down inside the hollow column, a support arm hinged to the bottom of each filter element mechanism, a main arm hinged to the power mechanism, and the main arm and the support arm concentrically hinged to the slider. The power mechanism drives the slider to slide up and down along the hollow column through the main arm, and the sliding slider drives the filter element mechanism to flip relative to the boss mechanism through the support arm.

[0009] Furthermore, the power mechanism includes an electric push rod mounted on the roof or ventilator. The movable end of the electric push rod passes through all the boss mechanisms and is hinged to the main arms of all the filter element mechanisms. Each main arm is hinged to a driven arm, and the driven arm is also hinged to the movable end of the electric push rod.

[0010] In summary, this utility model has the following beneficial effects: by setting up a filter mechanism on the roof that can be opened and closed, it effectively prevents dust, willow catkins, pollen and other fine impurities from entering the room, ensuring the environmental requirements of the factory, without affecting the normal lighting and ventilation of the workshop, setting the ventilation opening to a side air intake mode, effectively avoiding the occurrence of rain and snow, and allowing for the addition of photovoltaic power supply to improve the fault tolerance of the device operation.

[0013] The following is in conjunction with the appendix Figures 1-4 The present invention will be described in further detail below.

[0014] Side-opening and closing dustproof device, such as Figure 1 As shown, the device includes a boss mechanism 20, a filter element mechanism 30, a transmission mechanism 40, and a power mechanism 50. The side-opening and closing dustproof device is installed as a whole between adjacent ventilation openings 10 on the roof or ventilator. The boss mechanism 20 is fixedly installed on the roof or ventilator. The boss mechanism 20 is formed by two boss side panels 21, two boss vertical panels 22, and a boss light-transmitting and rainproof panel 23, and boss brackets 27 are added at key positions to strengthen the structure. Hinges 24 are provided on both sides of the boss mechanism 20, and the height of the hinges 24 is level with the lowest point of the boss light-transmitting and rainproof panel 23. The boss light-transmitting and rainproof panel 23 has symmetrically integrated rainproof panel pressure plates 25 and rainproof panel brackets 26 at both ends, and the rainproof panel pressure plates 25 and rainproof panel brackets 26 are located above the hinges 24.

[0015] like Figure 4 As shown, each boss mechanism 20 has a filter element mechanism 30 symmetrically hinged on both sides. The filter element mechanism 30 includes a filter frame, a filter element 32 filled inside the filter frame, and a filter element pressure plate 33 attached to the end of the filter frame 31. The filter element 32 has a modular design, can be customized to any size, and is easy to replace. The filter element 32 is generally made of filter cotton / cloth / mesh. The boss mechanism 20 can be adapted according to the number and size of the roof or ventilator openings. The filter material can be selected according to the cleanliness level requirements of the workshop. Filter cotton is generally made of PET (polyester fiber) and PP (polypropylene fiber), mainly for filtering ≥5μm particulate dust and suspended matter in the atmosphere. Filter cloth is generally made of PET (polyethylene terephthalate) synthetic fiber or nanofiber. PET (polyethylene terephthalate) synthetic fiber has a filtration efficiency of 90%-95% for 0.3μm and above; nanofiber material has a filtration efficiency of ≥99.9% for 0.3μm and above. The filter screen is made of metal mesh, glass fiber, or PP / PET composite material. The metal mesh is woven from stainless steel wire or sintered in multiple layers, filtering particles of 5μm and above. The glass fiber or PP / PET composite material has a filtration efficiency of ≥99.97% (H13 grade) for 0.3μm particles. The filter element plate 33 and filter frame 31 are made of aluminum alloy or galvanized steel sheet by bending. The filter element plate 33 is fixed to the frame with screws, facilitating the replacement of the filter element 32.

[0016] like Figure 4 As shown, each filter element mechanism 30 is equipped with a separate transmission mechanism 40, which operates in conjunction with a power mechanism 50 fixedly mounted on the roof. Each transmission mechanism 40 includes a hollow column 41 fixedly mounted inside the boss mechanism 20. The hollow column 41 has a through-flowing front and rear side, forming a sliding channel. A slider 42 that slides up and down is installed inside the hollow column 41. Each filter element mechanism 30 has a support arm 43 hinged to its bottom, and two support arms 43 are symmetrically hinged to the same sliding block. Figure 2 andFigure 3 As shown, a main arm 44 is hinged to the power mechanism 50. The main arm 44 and the support arm 43 are concentrically hinged to the slider 42. The power mechanism 50 drives the slider 42 to slide up and down along the hollow column 41 through the main arm 44. The sliding slider 42 drives the filter element mechanism 30 to rotate relative to the boss mechanism 20 through the support arm 43. The power mechanism 50 includes an electric push rod 51 installed on the roof or ventilator. The movable end of the electric push rod 51 is externally connected to a connecting rod 53. The connecting rod 53 passes through all the boss mechanisms 20 and is hinged to the main arms 44 of all the filter element mechanisms 30. Each main arm 44 is hinged to a driven arm 52, and the driven arm 52 is also hinged to the movable end of the electric push rod 51. The power push rod is simultaneously hinged to the transmission mechanism 40 of all groups through the connecting rod 53. The transmission mechanism 40 drives the filter element mechanism 30 to rotate relative to the boss mechanism 20. The screwed-in filter element mechanism 30 seals the corresponding ventilation port 10. The unfolding angle of the filter element mechanism 30 does not reach a completely horizontal position. The specific adjustment is made according to the setting of the ventilation port 10 on the factory roof.

[0017] The newly designed dustproof device effectively addresses dust, rain, snow, and lighting / ventilation needs. It not only effectively blocks dust, willow catkins, pollen, and other fine impurities from entering the room, ensuring air cleanliness under high-standard workshop conditions and reducing defective products caused by substandard air cleanliness, but more importantly, it prevents willow catkins from entering and causing fires, resulting in greater property damage and personal injury. It also does not affect workshop lighting and ventilation, and the side air intake prevents rain and snow from entering. The top polycarbonate protrusion for lighting and rain protection 23 serves as a lighting and rain protection component. Ventilation openings 10 are located on both sides of the protrusion mechanism 20, and each ventilation opening 10 is equipped with an openable / closable filter mechanism 30 to filter impurities in the air. The electric actuator 51 uses a safe DC 24V voltage, is powered by its own photovoltaic power supply, is energy-saving and environmentally friendly, and can be remotely operated from the ground.

[0018] It should be noted that this specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
