- Known deflector (SU 5224, Publ .: 04/30/1928), which is made of a spherical shape, made up of separate curved strips, with their lower ends connected to the ring put on the pipe, at the top are connected with a bolt.
- a radial roof fan (RU 2415305, publ .: 27.03.2011 Bull. N ° 9) is known from the prior art, containing an impeller made of curved blades in the form of a hollow spherical layer and mounted on the upper part of the gravity pipe, and a vertical axis, on which rotates the impeller, on the upper base of the impeller on radial rods there are vertical blades protruding beyond the spherical belt.
- the closest in technical essence is a roof-mounted radial fan for smoke removal and ventilation with an impeller (RU 2618416, publ. 05/03/2017 Bulletin N ° 13), which is made of curved blades in the form of a hollow ball belt, with a vertical axis on which the impeller rotates , on the upper base of which blades-cups from an aluminum body, and also use fluoroplastic bushings.
- an impeller RU 2618416, publ. 05/03/2017 Bulletin N ° 13
- the metal deflectors are heavy, which puts additional stress on the bearings and results in reduced bearing life. Secondly, the extra weight requires more wind to spin, which greatly reduces the overall useful life of the deflector.
- metal deflectors require frequent maintenance in the form of lubrication of bearings and moving parts, and given that they are located on roofs and are difficult to access, this often becomes very problematic.
- the technical problem to be solved by the utility model is to manufacture a turbo deflector from plastic and a design that takes into account all the shortcomings of the previous deflectors.
- the rotary deflector contains a base, a rim, blades, an axle, bearings, additionally contains one more rim, while both rims are made monolithic with bushings and are installed by bushings into each other by means of protrusions, thus forming an upper and a lower the rims in which the blades are installed, the cover is made in the form of a hemisphere, while the base, rims with bushings, the cover and the blades are made monolithically cast from plastic.
- Rotary deflector characterized in that the base has stiffening ribs and a seat enveloping the first ring with the second ring, the seat is made with a recess, the rim has stiffening ribs and a reinforced seat, which is enveloped by the second ring first, the cover is made with a rib rigidity in the form of a ring on the inner side, on which latches are installed for fastening to the rim, the blade has two horizontal stiffeners at the top and bottom and two latches for fastening to the rim.
- Rotary deflector according to claim 1 characterized in that the base, rims with bushings, cover and blades are made of polypropylene.
- Rotary deflector characterized in that the blade at the front has a thickness of 1 mm and thickens to the rear to 1.6 mm, after which it sharply becomes thinner, forming a beveled angle.
- a rotary or active deflector (turbo deflector) is installed at the outlet of natural ventilation pipes and is powered by wind energy. It does not consume electricity, and, therefore, this installation is economically viable.
- the device is designed to extract exhaust air from the room to the outside.
- the operation of a rotary deflector is 2-4 times more efficient than that of a conventional deflector, thereby increasing the efficiency of the entire exhaust system.
- the rotary deflector protects the ventilation duct from the ingress of precipitation and foreign objects, protects the roof from the formation of condensation by lowering the air temperature in the attic, prevents overheating of the interior, reduces fat deposits and dustiness of the ventilation ducts, and provides decorative design of the duct exit.
- figure 1 is a general view of the device
- figure 2 is a sectional view of the device
- the rotary deflector (turbo deflector) consists of a base 1 and a turbine head, which always rotates in one direction, regardless of wind direction.
- Base 1 is completely rigid, with six ribs, additionally fastened together in the middle by a common seat. As a result, the base is completely rigid and resistant to deformation.
- a landing skeleton (rims with bushings 2) is attached to the base with a rod (axis 6), which provides strength and rigidity of the entire structure, to which blades 4 and an aerodynamic cover 3 are attached.
- Base 1 has six stiffening ribs, a seat with a recess.
- the base is made monolithic. Thanks to the molding of the part, the base is perfectly flat and symmetrical. Thanks to six stiffening ribs and a reinforced center seat that wraps around the first ring with a second ring, the base is very strong.
- a recess in the shape of a sleeve with a depth of 10 mm is applied, due to which the axis sits tightly and is ideally centered vertically.
- Rims 2 are made monolithic. Thanks to the production of parts by injection molding, the rims are perfectly flat and symmetrical. With six ribs on the bottom and a reinforced center seat that wraps around a second ring, the rims are very strong.
- the rotary turbo deflector uses two rims installed in each other and fixed to each other by three protrusions on each of the bushings 5 mm high. These protrusions in the rims fit tightly into each other, which gives additional rigidity to the structure.
- the cast hub in the rim is reinforced with three stiffeners at the top. The two-rim hub is one piece that protects the metal axle from aggressive environments.
- the blades fit tightly into the upper and lower rims, thanks to twenty tapered holes in each rim in the form of a circle with protrusions on both sides, which securely fixes each blade.
- the seat for the bearing is recessed into the base of the rim from below, which reliably protects the bearing from aggressive media and ensures a longer bearing life.
- Cover 3 is made in the form of a hemisphere, which does not allow snow and ice to accumulate on it and lead to an imbalance in the structure. On the outside, it has twenty aerodynamic stiffeners to improve the deflector spinning moment in light winds. Thanks to the monolithic lid, it is perfectly flat, symmetrical and very durable. There is also a ring-shaped stiffener on the inner side, on which six fasteners-latches are installed, with which the cover is attached to the rim.
- the blade (blade) 4 is designed taking into account the aerodynamic properties of the aircraft wing and repeats its shape.
- the petal In the front part, the petal has a thickness of 1 mm and to the rear it thickens to 1.6 mm and then sharply becomes thinner, which forms a beveled corner. This shape allows the wind to create more thrust, which is of great importance when the wind is very weak.
- the petal has two horizontal (in iron vertical) stiffeners above and below, which gives additional strength to the structure.
- each of the petals has two cylindrical latches with protrusions on both sides, which securely fixes each blade. Thanks to the molded part, the petal is perfectly even, symmetrical, and very durable.
- the rotary (active) deflector is made mainly of the following materials: base, rim with sleeve, cover, blade — made of plastic or polypropylene, bolt and axle — made of galvanized steel, bearing made of metal.
- the aerodynamic cover improves the aerodynamic properties of the device, protects against precipitation, which prevents the bearing from freezing in winter due to moisture ingress.
- the rigidity of the entire structure Thanks to the above-described design of the deflector, the rigidity of the entire structure, torsional balance, quietness, improved performance (uniformity of rotation, rotation speed, rotation duration, minimum wind force to start rotation) and a much longer service life are achieved.
- the device works as follows.
- the wind hitting the blades makes the head of the device move, thereby discharging air in the system and improving traction.
- wind at a speed of 0.5 meters per second is sufficient, since all parts are made of lightweight materials. Accordingly, the stronger the wind, the higher the power of the device.
- the turbo deflector device provides autonomous operation and excludes reverse thrust.
- the declared rotary deflector has the following qualities (advantages):
- the plastic deflector is fully molded and manufactured in-house by means of molds and production lines, which virtually eliminates manual labor and guarantees perfect precision, symmetry and balance to ensure uniform rotation. It also ensures quick and easy production, no scrap, giving any color uniform by adding a dye to the raw material, and, as a result, low production costs.
- the design of all parts is thought out in such a way that the entire deflector is rigid, tightly assembled, does not loosen over time and is durable. For this, stiffening ribs are made on the rims, cover, base and blades, latches on the blades are cylindrical in shape with protrusions on both sides. The construction of the base with the axle inserted into it is also aimed at rigidity construction and precise balancing.
- the above described deflector design achieves overall rigidity, torsional balance, quiet operation, improved performance and a much longer service life.
