Description

Technical Field

[0001] The invention relates to the technical field of roof ventilators, in particular to an emission-reducing and environmentally friendly roof ventilator. Background Art

[0002] Roof ventilators are also called roof natural ventilators, roof natural ventilators, etc. They mainly revolve around the aerodynamic wind load model theory. When wind acts on an object, the windward side is pressure, and the leeward side and the side along the wind are suction. Roof ventilators are divided into: strip roof ventilators and spherical roof ventilators. Among them, strip roof ventilators are divided into streamlined roof ventilators and thin roof ventilators. The snow load capacity of roof ventilators depends on factors such as the design form of the steel frame, the material specifications of the steel frame, and the thickness of the rain shield. Among them, the selection of component material specifications is very important. First of all, it should fully ensure that the wind and snow load requirements are met to solve indoor ventilation, lighting, smoke exhaust and other needs. At the same time, it is also necessary to avoid unnecessary selection of oversized specifications. The arc structure of the natural ventilator has excellent structural strength. This strength does not need to rely on large-sized steel structures like shed-type skylights to achieve, thereby greatly reducing the cost of the ventilator. The design of the specifications of the supporting components of the building on which the ventilator relies, in addition to fully considering the impact of wind, snow loads, and earthquakes, in fact, most of the supporting structures of the factory building serve the roof load. Therefore, the selection of material specifications for the ventilator components is very important. First of all, it should be fully guaranteed to meet the requirements of wind and snow loads. At the same time, it is also necessary to avoid unnecessary selection of excessive specifications to avoid increasing the deadweight load, increasing the load on the workshop roof and increasing the cost. Ventilation is very important for human health, not only to provide fresh air. Decoration, furniture, office equipment, etc. will emit a large amount of harmful gases. Poor ventilation makes it difficult to dilute and diffuse various pollutants. If people are in this environment for a long time, the damage to the body is self-evident. Staying indoors for a long time to avoid external polluted air is obviously useless. People are in a room with poor space circulation, which is more harmful to the human body.

[0003] For example, the patent document with the announcement number CN113531728B discloses an emission-reducing and environmentally friendly roof ventilator, which includes: a shell, a rain shield is arranged on the shell, two drainage boxes are arranged in the shell, each drainage box is slidably provided with a movable plate, and a plurality of through holes are opened on the movable plate; two mounting blocks, the two mounting blocks are respectively connected to the corresponding drainage boxes, each mounting block is provided with a fixed rod, the fixed rod is respectively connected to a plurality of annular blocks through a plurality of first torsion springs, each annular block is fixedly connected to two rotating blocks, and a plurality of movable rods are fixedly connected to the movable plate. The present invention can effectively prevent rainwater from splashing into the room even in heavy rain, thus preventing rainwater from entering the room and causing indoor humidity, so that daily activities in the room can be carried out normally, thereby improving the practicality of the roof ventilator.

[0004] However, during actual use, this structure can often only perform simple operations to prevent water ingress on rainy days, and cannot perform adaptive switching operations for rainy days and sunny days, resulting in poor overall emission reduction and environmental protection effects of the roof ventilator. A large amount of electricity is required at all times to perform internal ventilation drive operations, and more efficient emission reduction and environmental protection ventilation operations cannot be achieved. In addition, when the equipment is in the state of preventing water ingress on rainy days, it cannot perform adaptive ventilation operations on the house, making it impossible for the high-quality air outside on rainy days to be properly ventilated with the room. At the same time, the air purification structure used by the equipment is often an integrated structural design, and the internal filter element cannot be quickly disassembled and replaced, and cannot be installed for daily use needs. Therefore, it is urgent to design an emission reduction and environmental protection roof ventilator to solve the above problems. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects: The emission reduction and environmentally friendly roof ventilator, through the ventilation frame, the first ventilation side frame, the second ventilation side frame, the side adjustment bend seat, the fan assembly, the inner tank frame, the air pump, the flow equalizing seat, the limit frame, the shrinkage cover, the positioning groove, the top pressure air bag column, the rain shield, the power generation board, the hydrophobic coating, the photovoltaic panel body, the limit slider, the adjustment air bag column, the damping rubber pad, the positioning rubber strip, the limit slide groove, the exhaust valve seat, the filter bend groove, the installation base and the installation groove, can make the equipment to perform more efficient emission reduction and environmentally friendly roof ventilation operation. In the actual use process, the staff first passes the ventilation frame as a whole through The mounting bases and mounting grooves on both sides of the bottom are fixedly installed on the vents on the roof to cover the vents as a whole. Daily, the fan group inside the ventilation rack is started to control the air in the house from the vents, and the air pump at one end of the ventilation rack is started to regulate the air pressure inside the ventilation rack. During normal operation on sunny days, the exhaust valve seat at one end of the limiting slide groove at the bottom of the side adjustment turn seat can be used to inflate the adjusting airbag column on the power generation panel, so that it can be moved and adjusted along the limiting slide groove at the bottom of the side adjustment turn seat, thereby adjusting the left and right groups. The power generation panel is pushed to both sides of the ventilation rack as a whole. At this time, photovoltaic power generation can be carried out and the motor can be stored through the photovoltaic panel body inside the power generation panel to ensure the operation of the equipment as a whole on rainy days or at night, thereby ensuring that the equipment can be used for emission reduction and environmental protection. When it rains, the same method can be used to control the air pump to move the rain shield on the top of the side adjustment seat through its limit slider and the adjustment airbag column along the limit slide grooves at both ends of the side adjustment seat surface and the exhaust valve seat to the top center of the ventilation rack for convergence, thereby A docked rain shield structure is formed on the top of the ventilation rack, and the hydrophobic coating on the surface of the rain shield performs rapid hydrophobic diversion operations. The damping rubber pads and positioning strips at the upper and lower ends of the side adjustment crutch seat perform positioning operations for each adjustment of the rain shield and the power generation panel. At the same time, the air pump can inflate air into the limit frames at both ends of the ventilation rack surface through the flow equalizing seat, so that the top pressure airbag column inside the shrinkage cover is limited and fixed at the positioning groove facing the telescopic docked rain shield, ensuring a more stable positioning and waterproofing operation, realizing efficient switching and use operations of the equipment, and reflecting the practicality of the equipment design.

[0017] The emission-reducing and environmentally friendly roof ventilator further improves the overall use effect of the equipment by arranging a ventilation frame, a fan assembly, a bottom cover, a pumping frame, a ventilation valve, a push airbag cover, a purification filter element, a conical lifting frame, a hydrophobic ventilation core, a rain sensor, a guide ramp, a lifting slider, a lifting airbag column, a ventilation side cover, a ventilation inclined mesh groove, a flow frame, a flow pipe, a lifting slide, a hydrophobic pad, a flow grille and a drain seat. In daily use, the rain sensor on the top of the conical lifting frame can perform real-time monitoring operations on the rainfall. In daily weather when the rainfall is light, rainwater can be discharged directly from the guide inclined plates along the two sides of the conical jacking frame to the flow grilles on both sides of the inner wall of the inner tank frame, and then flow in both directions from the flow pipes at the bottom of the flow frame, and finally discharged from the drainage seats at the four corners of the two ends of the ventilation frame. The hydrophobic pads at the top of the inner wall of the inner tank frame can cooperate with the ventilation inclined mesh grooves inside the ventilation side covers on both sides to blow air into the first ventilation side frame and the second ventilation side frame on both sides, so as to continuously perform efficient roof ventilation flow. Operation will not affect the normal operation of the equipment. However, when the rain sensor detects that the rainfall is too heavy and it is necessary to block rain and prevent water ingress, the two sets of rain shields can be docked at the top of the ventilation frame. The internal inflation part of the lifting airbag column can be inflated through the air pump, so that the lifting slider at one end of the lifting airbag column can be lifted along the lifting slide grooves at the four corners of the inner wall of the inner tank frame. The lifting operation is directly connected to the bottom center of the two sets of rain shields to achieve the bottom reinforcement operation of the anti-water ingress structure. The hydrophobic ventilation core at both ends of the conical lifting frame can be used for ventilation with a small flow rate to ensure the ventilation and ventilation needs of indoor air on rainy days. At the same time, the pumping frame can be placed inside the bottom cover as a whole on a daily basis, so as to realize the replacement and use of the purification filter element inside the pumping frame. When the pumping frame is sent into the bottom cover, the ventilation valve can be docked with the inside of the air pump, and then inflated from the ventilation valve, so that after the airbag cover is inflated, the purification filter element is sent to the first ventilation side frame and the second ventilation side frame on both sides of the ventilation frame to perform daily ventilation airflow reduction and purification operations, which reflects the comprehensiveness of the equipment design.

[0023] Working principle: When in use, the user first fixes the ventilation rack 1 as a whole to the vent on the roof through the mounting base 43 and the mounting groove 44 on both sides of the bottom, and covers the vent as a whole. Daily, the fan group 5 inside the ventilation rack 1 is started to control the air in the room from the vent, and the air pump 25 at one end of the ventilation rack 1 is started to regulate the air pressure inside the ventilation rack 1. During normal operation on sunny days, the exhaust valve seat 40 at one end of the limiting slide groove 39 at the bottom of the side adjustment bend seat 4 can be used to inflate the adjusting air bag column 36 on the power generation panel 32, so that it can be moved and adjusted along the limiting slide groove 39 at the bottom of the side adjustment bend seat 4, thereby moving the left and right groups of power generation panels 32 as a whole to The pushing operation is performed on both sides of the ventilation rack 1. At this time, the photovoltaic panel body 34 inside the power generation panel 32 can be used to perform photovoltaic power generation and store the motor to ensure that the equipment can be used for overall operation on rainy days or at night, thereby ensuring that the equipment can be used for emission reduction and environmental protection. When rainy days occur, the same method can be used to control the air pump 25 to move the rain shield 31 on the top of the side adjustment crooked seat 4 through its limiting slider 35 and the adjusting air bag column 36 along the limiting slide grooves 39 at both ends of the surface of the side adjustment crooked seat 4 and the exhaust valve seat 40 to the top center of the ventilation rack 1 for convergence operation, thereby forming a docking rain shield structure at the top of the ventilation rack 1, and the hydrophobic coating 33 on the surface of the rain shield 31 is quickly hydrophobic. Flow operation, the damping rubber pads 37 and the positioning rubber strips 38 at the upper and lower ends of the side adjustment turning seat 4 are used to perform the positioning operation of the rain shield 31 and the power generation board 32 each time the adjustment is performed. At the same time, the air pump 25 can inflate the inside of the limit frames 27 at both ends of the surface of the ventilation frame 1 through the flow equalizing seat 26, so that the top pressure airbag column 30 inside the shrink cover 28 is limited and fixed at the positioning groove 29 facing the rain shield 31 that has been telescopically docked, ensuring that it performs more stable positioning and waterproofing operations, and realizing efficient switching and use operations of the equipment. In daily use, the rain sensor 14 on the top of the conical lifting frame 12 can perform real-time monitoring operations on the rainfall. When the weather and rainfall are small, rainwater can directly flow along the two sides of the conical lifting frame 12 from the guide inclined plate 15 The air is discharged from the flow grilles 24 on both sides of the inner wall of the inner tank frame 11, and then flows in both directions from the flow pipe 21 at the bottom of the flow frame 20, and finally discharged from the drainage seats 42 at the four corners of the two ends of the ventilation frame 1.
