Specific implementation

[0024] The technical scheme in the embodiments of the utility model will be apparently and completely described below with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the range of the utility model protection.

[0025] Please refer to Figures 1-6 The utility model discloses a kind of portable tethered floating power generation devices in the embodiment, including floating air bag 1, air inlet duct 2 is formed in floating air bag 1, air inlet duct 2 inner wall is detachably installed with wind driven generator 3 by connecting structure, the output shaft of wind driven generator 3 is fixed with fan blade 4, airflow enters by air inlet duct 2, makes fan blade 4 rotate, wind driven generator 3 converts kinetic energy into electric energy, realizes wind power generation.

[0026] Among them, the outer wall of floating air bag 1 is fixed with several hooks, which are used to connect the tethering cables. Three hooks are arranged at the front end, five hooks are arranged at the middle part, and three hooks are arranged at the rear end. All the hooks are equidistantly arranged on the floating air bag 1. The length of the multiple tethering cables is adjusted by a ground winch to adjust the pitch attitude. The tethering cables are made of lightweight carbon fiber cables. The floating air bag 1 has a streamlined aerodynamic shape design, and a tail wing is arranged at the tail of the floating air bag 1. The tail wing includes a pair of balance tail wings and a vertical tail wing, which can effectively enhance the floating stability.

[0027] The floating air bag 1 has a hollow cylindrical design. The outer diameter of the cylinder is 4 m, the overall length is 3.5 m, and the tail wing is 2.72 m high. The overall design is streamlined to reduce air resistance. The material of the floating air bag 1 is PVC reinforced film, which has air tightness, deformation resistance and aging resistance. The tethering cables are made of lightweight carbon fiber cables, and the fan blades 4 are made of high-performance ABS plastic material.

[0028] The air inlet duct 2 also adopts a variable diameter design to realize wind speed improvement. The variable diameter duct size is: the inlet diameter is 2.7 m to the contraction section 1.55 m, and the duct ratio is 3:1. When the airflow passes through the contraction section, the cross-sectional area decreases, causing the flow rate to increase, and the Bernoulli effect. The actual measured wind speed can be increased by 2.5-3 times. The inner wall of the air duct adopts a nano-level smooth coating with a roughness Ra<0.1 μm, which reduces the turbulent loss of airflow and improves the wind energy utilization rate to 3 times that of traditional vertical axis wind turbines.

[0029] The air inlet duct 2 has an air inlet diameter of 0.78 m and a diameter of 0.9 m at the narrowest point. It adopts a double-curved variable diameter design with a tapering-tapering type. The inlet section contraction angle is controlled within 12 degrees, and the outlet section diffusion angle is maintained within 7 degrees. The fan blade 4 installation plane is the smallest diameter narrowest part of the air inlet duct 2 to maximize the use of the duct contraction to increase the fan blade wind speed.

[0030] As to how to realize the connection between the wind turbine 3 and the floating air bag 1, as shown in Figures 3-6 The connection structure includes two groups of fixed rods 5 fixed to the shell of the wind turbine 3, which are uniformly arranged along the circumferential direction. The outer end of each group of fixed rods 5 is connected with a fixed ring 6.

The two groups of clamping heads 7 are oppositely arranged, and the opposite surfaces of the two groups of clamping heads 7 are provided with circular grooves. The three surfaces of the clamping head 7 are provided with clamping grooves communicating with the circular grooves.

[0031] During installation, the connection between the fixed ring 6 and the fixed rod 5 is clamped into the clamping head 7, the fixed ring 6 is inserted into the two side clamping grooves, and the fixed rod 5 is inserted into the middle clamping groove, thereby realizing the installation of the wind turbine 3, which is simple and fast.

[0032] In addition, since the two groups of clamping heads 7 are oppositely arranged, the opposite surfaces of the opposite pair of clamping heads 7 in the two groups of clamping heads 7 are commonly provided with a connecting piece, which can be used to abut the connection between the fixed rod 5 and the fixed ring 6 to the corresponding clamping groove of the clamping head 7, thereby further improving the stability of the installed wind turbine 3.

By the fixed sleeve 9 and the movable sleeve 10, the two groups of fixed rings 6 are respectively abutted to the corresponding clamping heads 7, thereby realizing the stable installation of the wind turbine 3.

[0034] The outer periphery of the movable sleeve 10 and the fixed sleeve 9 is fixed with a rotating handle 11, the cross section of the rotating handle 11 is pentagonal or hexagonal, which can facilitate the rotation of the movable sleeve 10.

[0035] Due to the floating air bag 1 may sway during flight, the movable sleeve 10 is rotated by itself, which causes it to be separated from the clamping head 7, in order to avoid this situation, the outer periphery of the threaded rod 8 is sleeved with a compression spring 12 between a pair of rotating handles 11, the opposite surfaces of the rotating handle 11 are provided with containing grooves, the compression spring 12 is arranged between the inner walls of the containing grooves, when the movable sleeve 10 and the fixed sleeve 9 are inserted into the corresponding clamping head 7, the compression spring 12 is still in a compressed state, the tension of the compression spring 12 makes the movable sleeve 10 not easy to rotate.

[0036] In addition, in order to facilitate the carrying of the floating power generation device, as shown, Figure 1 The front surface of the floating air bag 1 is sewn with a cloth bag 13, the other side of the cloth bag 13 is provided with a double-sided zipper 14, the back of the cloth bag 13 is adhered to the outer wall of the floating air bag 1 through a magic tape 15, the double-sided zipper 14 of the cloth bag 13 can be pulled open, and the floating air bag 1 after deflation can be put into the cloth bag 13 by turning to the left side and turning over, and then the double-sided zipper 14 is closed, so that the power generation device can be conveniently carried.

[0037] The back of the cloth bag 13 is sewn with a magic tape hook surface, and the surface of the floating air bag 1 is sewn with a magic tape fluff surface corresponding to the magic tape hook surface.

[0038] In the above embodiment, when the utility model is used, the floating air bag 1 is inflated first, then the connecting parts of the two groups of fixed rings 6 and fixed rods 5 are respectively clamped into the corresponding clamping heads 7, then one end of the fixed sleeve 9 is inserted into the corresponding circular groove of the clamping head 7 to abut the fixed ring 6 and the fixed rod 5, and then the movable sleeve 10 is rotated to rotate outward on the outer side of the threaded rod 8 until the outer end of the movable sleeve 10 is inserted into the corresponding clamping head 7, and then the two groups of fixed rings 6 and fixed rods 5 are respectively abutted in the corresponding clamping heads 7 by the fixed sleeve 9 and the movable sleeve 10, so that the wind driven generator 3 is stably installed.

[0039] After use, the wind driven generator 3 is taken out of the floating air bag 1, the right side of the cloth bag 13 is separated from the air bag, the floating air bag 1 is deflated and folded together, and after the double-sided zipper 14 of the cloth bag 13 is pulled open, the folded air bag can be opened in the opposite direction and placed in the cloth bag 13, so that the portability of the device is improved.
