[045] Detailed description of the invention
[046] The technical scheme in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative labor are within the scope of protection of the present invention.
[047] In order to make the above objects, features and advantages of the present invention more obvious and easy to understand, the present invention will be further explained in detail with reference to the drawings and specific embodiments.
[048] With reference to Figs. 1-5, the invention provides a BIM-based building wind energy simulation device, which comprises two symmetrically arranged two-story building bodies 1, a channel 2 is connected between the top layers of the two building bodies 1, a cross beam 3 is erected between the two building bodies 1, a wind power generation assembly 4 is arranged on the front end face of the cross beam 3, and the wind power generation assembly 4 is located at the bottom of the channel 2. In this embodiment, the building 1 is a common two-story building in a village. It is designed that each household should build two buildings 1, which are connected to the top floor through a passage 2, so that it is convenient to walk around. Moreover, the building 1 has a large space and is suitable for living, so that the space between the two buildings 1 and the passage 2 serves as a ventilation position. A beam 3 is arranged at this position, and the wind power generation assembly 4 is installed on the beam 3. When the outside wind passes through this position, the fan blades of the wind power generation assembly 4 are driven to rotate and generate electricity by wind energy. When the wind energy is insufficient, the daily switch can be turned on, and the power supply mode can be switched at will, which further reduces the power supply energy consumption and improves the utilization of wind energy.
[049] The connecting assembly comprises two protective shells 5 for providing dust-proof, waterproof and anti-corrosion functions to the connecting position between the building body 1 and the beam 3, and prolonging the service life. The two protective shells 5 are respectively arranged at two ends of the beam 3, and the protective shells 5 are fixed on the building body 1; One end of the protective shell 5 close to the building body 1 is fixed with a first shock pad 6; the end of the beam 3 extends into the protective shell 5 and is fixed with a connecting plate 7.The connecting plate 7 is in contact with the first anti-shock pad 6, the outer side of the connecting plate 7 is sleeved with a limiting block 8 which is fixed on the first anti-shock pad 6, the end of the beam 3 is sleeved with a second anti-shock pad 9, and the end of the second anti-shock pad 9 far from the connecting plate 7 is in contact with the end face of the protective shell 5An opening 12 is formed at one end of the protective shell 5 away from the building body 1, and a sealing ring 13 is fixed at the opening 12. The end of the beam 3 extends into the opening 12 and is fixedly connected with the connecting plate 7. The bolt 10 extends into the protective shell 5 through the sealing ring 13 and fixes the first and second shock pads 6 and 9 and the connecting plate 7. The materials of the first and second shock pads 6 and 9 are neoprene.The frequent passage of external wind and the work of wind power generation assembly 4 easily cause the beam 3 to resonate, which in turn causes the building body 1 to resonate. The resonance is eliminated to the maximum extent by the two layers of anti-vibration pads in the connecting assembly. The beam 3 is stably and fixedly connected with the building body 1 under the action of anti vibration pads, limiting blocks 8 and bolts 10, and the sealing performance at its opening 12 is ensured by the sealing ring 13.
[050] The rear end face of the beam 3 is detachably connected with a wind measuring component, and the top face of the beam 3 is detachably connected with a wind direction measuring component, which is used for synchronizing the rotating speed of the wind energy generating component 4 and measuring the wind strength, and for detecting the wind direction flowing between two buildings 1 in real time. The wind measuring component and the wind direction measuring component respectively adopt a simple wind measuring instrument and a wind direction measuring instrument to respectively detect wind power and wind direction, and do not need to purchase a wind speed and wind direction measuring instrument, thus reducing the use cost.
[051] The side surface of the building body 1 is an arc surface 11, and the top surface and the bottom surface of the building body 1 are oval structures. The long side of the ellipse of the building body 1 is eight times as long as the short side, and the curved surface 11 on the side can increase the flow of guided wind and compensate the air volume of the wind power generation assembly 4. The wind speed passing through this position can be enhanced by about 20%. The curved surface 11 guides the flowing wind to pass in an S-shaped path, which can increase the power by 15% as a whole.
[052] The wind measurement assembly includes a synchronous gear 14 which is axially connected to the rear end face of the beam 3, and a tachometer 15 is installed on the synchronous gear 14. The tail end of the impeller shaft of the wind power generation assembly 4 extends out of the beam 3 and is connected with the synchronous gear 14 with a synchronous rack belt 16.
[053] The wind direction measuring assembly comprises a lead screw 17, two ends of which are respectively connected with a motor 18 and a shaft seat 19, which are detachably connected to the top surface of the cross beam 3, a slider 20 is slidably connected to the lead screw 17, a wind direction measuring instrument 21 is fixed on the slider 20, and the motor 18 drives the lead screw 17 to rotate automatically, so that the slider 20 moves linearly on the lead screw 17 and drives the wind direction measuring instrument 21 to move left and right in the ventilation position.
[054] Transducers of sensors in the wind direction measuring instrument 21 are code wheels and photoelectric components. When the weathervane rotates with the change of the wind direction, the shaft drives the code wheel to rotate in the gap of the photoelectric component, and the generated photoelectric signal is output corresponding to the Gray code of the wind direction at that time. The transducer of the sensor can adopt a precision conductive plastic potentiometer, so that the variable voltage signal is output at the movable end of the potentiometer.
[055] A simulation method of a BIM-based building wind energy simulation device comprises the following specific steps: step 1: simulating construction, performing simulation construction on a building body 1 by adopting BIM technology, showing the solid form of the building body 1 in advance, and correcting problems in the actual construction process in time; when the resonance phenomenon caused by wind force on a beam 3 is involved, the phenomenon is overcome when designing a connecting component, and the problem of time delay caused by improper design is reduced;
[056] Step 2: Energy-saving design, adopting BIM technology, adjust the orientation and orientation of the space between two buildings 1 through wind field analysis, and then accurately lay out the position of the wind power generation assembly 4, and then simulate and analyze the annual energy consumption, heating and cooling load and lighting power resources of the buildings 1 during use, and predict the energy saving effect;
[057] Step 3: Analyze the optimal energy-saving design scheme of building 1 model under the typical environment of wind power station; The selection of external wall insulation materials, the selection of windows and the conversion and utilization of wind energy in building 1 are compared and analyzed.
[058] The method comprises the following steps: when building a building body 1 model, acquiring the shape distribution of each component in the first BIM model and the second BIM model according to the geometric information of each component in the first BIM model and the second BIM model;
[059] Coordinate systems of the first BIM model and the second BIM model are registered, and position similarity between each component in the first BIM model and each component in the second BIM model is calculated according to the registered position information of each component;
[060] According to the geometric similarity and position similarity between each component in the first BIM model and each component in the second BIM model, the component matching result between the first BIM model and the second BIM model is obtained by comparing the matched components.
[061] In the description of the invention, it should be understood that the orientation or position relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the orientation or position relationship shown in the attached drawings, which is only for the convenience of describing the invention, instead of indicating or implying that the device or element in question must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the invention.
