Definitions

  • the invention relates to a protective device according to the preamble of claim 1.
  • Protective devices that are used in particular for ventilation systems are often made up of protective elements arranged concentrically around a center, such as e.g. Lattice rings, formed, which are fixed to support struts and which form a protective space with their interior.
  • the distance (opening) between the protective elements which, as protective constructions, offer a material obstacle that in particular restricts the movement of a human body and / or a part of the body in order to prevent a hazardous area (e.g. a rotating impeller) from being reached, for safety reasons Reasons not to be too big.
  • a hazardous area e.g. a rotating impeller
  • conventional protective devices therefore have a high weight, since a large number of protective elements must be arranged on them.
  • a protective device which is formed from a one-piece injection molded part.
  • a high air throughput can also be achieved by increasing the flow speed by increasing the speed of the fan unit.
  • a vortex street which according to its discoverer is referred to as Kármán vortex street, can form on the side of the protective element around which the flow flows, and consists of two rows of vortices with opposite directions of rotation.
  • the character of the vortex formation is essentially determined by the Reynolds number, a key figure used in the flow theory for the flow state. If the flow velocity increases or the viscosity of the fluid decreases (e.g. with air compared to water), the Reynolds number increases.
  • the invention and its advantages is defined by claim 1.
  • This device has the advantage that it has at least one protective element which comprises an elongated, twisted profile having a polygon in cross section, the geometric design of the protective element significantly reducing the built-in mass, so that there is a reduction in weight.
  • the geometric design of the protective element if necessary. the detachment of Kármán vertebrae and thus reduce noise.
  • the elongated profile of a protective element is made of solid material.
  • the elongated profile of a protective element is a hollow body (for example a triangular or square tube).
  • the circumferential center of the elongated profile is located on the longitudinal axis of the elongated profile.
  • a protective element has different twist angles and / or different twist continuities.
  • several protective elements have different twist angles and / or different twist continuities.
  • the polygon is a triangle, quadrangle, polygon or a star profile.
  • the triangle is an equilateral triangle or the polygon is a regular polygon.
  • the protective device has a plurality of protective elements arranged at a distance from one another.
  • the distance (opening) that exists between two protective elements thus corresponds to the distance that exists between the two boundaries that delimit the respective protective space.
  • the protective space is limited by the radius.
  • the distance (opening) between two elongated profiles thus corresponds to the distance between their circles.
  • the distance (opening) between the round pipes corresponds to the distance between the outer circumferences.
  • the protective device is designed as a protective grille and / or as a motor suspension. Further advantages and advantageous embodiments of the invention can be found in the following description, the drawing and the claims.
  • Fig. 1 shows a perspective view of a protective device 1 according to the invention in the form of a protective grille which consists of four support struts 2 onto which concentric protective elements 3 in the form of grating rings are welded.
  • Each support strut 2 consists of two parallel flat profiles 4, which are angled twice over the high edge at different angles, the inner ends of which are connected to an inner flange ring 5 and the outer ends of which are connected to an outer flange ring 6.
  • the flat profiles 4 instead of the flat profiles 4, differently shaped profiles, for example round profiles, can also be used.
  • two round struts 7 are arranged in the same division.
  • the protective elements 3 are each connected at their intersection points (joints 8) with the flat profiles 4 and the round struts 7 by welding.
  • the short line contact between protective element 3 and flat profile 4 is also regarded as a crossing point.
  • Fig. 2 and Fig. 3 show front views of an elongated profile 9 of a protective element 3.
  • the elongated profile 9 has a triangular cross-sectional area 10, wherein corner points 11 of the elongated profile 9 are located on a circumference 14 having a circumferential center 12 and a radius 13.
  • the elongated profile 9 which can be a triangular wire, for example, about its longitudinal axis, which is perpendicular to the image plane and extends through the circumferential center 12
  • the protective space formed by the elongated profile 9 increases, so that the initially twisted Condition given protection space, which is given by the edge length of the elongated profile 9, increases to the radius of the circumference 14.
  • the triangular cross-sectional area 10 of the elongated profile 9 is only 41.3% of the area of a full round wire, the circumference of which is through Protection area is defined, corresponds to the radius 14, a material saving of 58.7% is achieved with the same protection area.
  • the elongated profile 9 is shown as a solid material. It would be conceivable that instead of the elongated profile 9 made of solid material, an elongated hollow body (eg a triangular tube) with the same circumference is used. By using an elongated hollow body and twisting it, the material savings could be increased even further.
  • the elongated profile 9 is designed as a star profile, which has a cross-sectional area 10.
  • the corner points 11 of the star profile are located on a circumference 14 having a circumferential center point 12.
  • the Fig. 5 shows a side view of an elongated profile 9 of a protective element 3 and the Fig. 6 shows a perspective view of an elongated profile 9 of a protective element 3 according to Fig. 2 with indicated cross-sectional areas 10.
  • the elongated profile 9, which has a triangular cross-sectional area 10 is twisted about the longitudinal axis 16, as a result of which the protective space is enlarged.
  • Fig. 7 shows a front view of an elongated profile 9 of a protective element 3 according to Fig. 2 with indicated cross-sectional areas 10.
  • the twisting creates a surface structure that reduces the detachment of Kármán vertebrae, so that noise is counteracted.
