DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] The present invention provides a high-strength power tower special-shaped frame structure, including a shock-absorbing isolation part 1, the shock-absorbing isolation part 1 includes an upper support plate 19 and a lower support rod 21, the upper support plate 19 is connected to the lower support rod 21 by a connecting column 20, the outer ring of the connecting column 20 is alternately provided with reinforcing plates 23 and buffer plates 22, the upper support plate 19, the lower support rod 21, the reinforcing plate 23 and the buffer plate 22 are wrapped by a wrapping sleeve, and the material of both the wrapping sleeve and the buffer plate 22 can be rubber. Through the setting of the shock-absorbing isolation part 1, when the structure is in use, the shock-absorbing isolation part 1 can be buffered by the buffer plate 22 and the wrapping sleeve, thereby reducing the influence between two adjacent shock-absorbing isolation parts 1 and improving the stability of the structure when used.

[0027] Two adjacent shock-absorbing isolation parts 1 are connected by support rods 2 and reinforcing rods 3. The reinforcing rods 3 are located between the two support rods 2. The reinforcing rods 3 between the two adjacent support rods 2 are cross-arranged. The two adjacent reinforcing rods 3 are connected by a connecting structure. The support rods 2 and the reinforcing rods 3 are connected to the shock-absorbing isolation part 1 by another connecting structure. The connecting structure includes a threaded column 4 and a nut 6 adapted to the threaded column 4.

[0028] The top and bottom of the shock-absorbing isolation part 1 are both provided with threaded holes 5, and the middle part of the threaded hole 5 is fixedly connected with a threaded column 4, and the top of the threaded column 4 is provided with a limiting groove, and both ends of the inner cavity of the limiting groove are movably connected with positioning blocks 16, and the positioning block 16 is fixedly connected to the threaded column 4 through a spring 18, and the top of the inner cavity of the limiting groove is movably connected with a pressure block 14, and the pressure block 14 is fixedly connected to the threaded column 4 through a spring 2 17, and the positioning block 16 is fixedly connected to the pressure block 14 through a pull rope 15. Under the action of external force, the position of the pressure block 14 can be changed. When the pressure block 14 moves downward, the pulling force of the pull rope 15 on the positioning block 16 is reduced. Under the action of the rebound force of the spring 18, the positioning block 16 can move outward. When the restriction on the pressure block 14 is released, under the action of the rebound force of the spring 2 17, the pressure block 14 can be reset, and the pressure block 14 can drive the positioning block 16 to reset through the pull rope 15.

[0029] The outer ring of the bottom end of the nut 6 is provided with an external thread that is compatible with the threaded hole 5, and the bottom end of the nut 6 is provided with a fixing groove, which is threadedly connected to the threaded column 4. The setting of the external thread and the fixing groove improves the firmness of the connection between the nut 6 and the shock-absorbing isolation part 1. The top of the inner cavity of the fixing groove is fixedly connected with a pressure column 13 that is compatible with the limiting groove. When the nut 6 is threadedly connected to the threaded column 4, the pressure column 13 can squeeze the pressure block 14. Both sides of the top of the fixing groove are provided with positioning grooves that are compatible with the positioning block 16. When the positioning groove and the positioning block 16 are at the same height, the positioning block 16 can be inserted into the positioning groove, and the positioning block 16 is used to limit the nut 6 to prevent the nut 6 from loosening, thereby improving the reliability of the connection structure.

[0030] The top and bottom of the support rod 2 are fixedly connected with a fixing sleeve 11, and the two ends of the reinforcing rod 3 are fixedly connected with a connecting plate 7. The end of the fixing sleeve 11 and the middle of the connecting plate 7 are provided with a through hole 10, and the bottom end of the nut 6 is movably connected to the through hole 10, and the fixing sleeve 11 is a C-shaped structure. The inner cavity of the fixing sleeve 11 is adapted to the shock-absorbing isolation part 1. Through the setting of the fixing sleeve 11, the fixing sleeve 11 can wrap the threaded column 4, thereby improving the strength of the connection between the support rod 2 and the shock-absorbing isolation part 1, thereby improving the strength of the special-shaped frame structure.

[0031] The thickness of the fixing sleeve 11 is not less than the distance between the end of the threaded column 4 away from the shock-absorbing isolation part 1 and the shock-absorbing isolation part 1. When the fixing sleeve 11 is sleeved on the shock-absorbing isolation part 1, the threaded column 4 is hidden in the through hole 10 on the fixing sleeve 11. The distance between the connecting piece 7 and the end of the reinforcing rod 3 is the same as the thickness of the fixing sleeve 11, and the bottom of the fixing sleeve 11 connected to the top of the support rod 2 contacts the connecting piece 7 at one end of the reinforcing rod 3, and the connecting piece 7 at the other end of the reinforcing rod 3 contacts the top of the fixing sleeve 11 connected to the bottom of the other support rod 2.

[0032] The outer ring of the nut 6 is fixedly connected with a compression ring 12, and the outer diameter of the compression ring 12 is larger than the inner diameter of the through hole 10. The size of the compression ring 12 can be set according to needs and is not limited here. The sum of the thickness value of the connecting piece 7, the thickness value of the fixing sleeve 11 and the depth value of the threaded hole 5 is the same as the distance value between the compression ring 12 and the bottom of the nut 6. When the bottom of the nut 6 contacts the bottom of the inner cavity of the threaded hole, the compression ring 12 fits tightly with the side of the connecting piece 7 away from the fixing sleeve 11. The nut 6 is used to limit the fixing sleeve 11 and the connecting piece 7, so that the support rod 2 and the reinforcing rod 3 can be connected to the shock-absorbing isolation part 1 at the same time, thereby improving the construction efficiency of the special-shaped frame structure of the power tower.

[0033] From the above description, it can be seen that the special-shaped frame structure can have a shock-absorbing function when in use, reduce the impact of vibration on the power tower, and improve the stability of the power tower. The connecting structure can be used to connect the support rod 2 and the reinforcing rod 3 to the shock-absorbing isolation part 1 at the same time, thereby improving the construction efficiency of the special-shaped frame structure of the power tower. The position of the nut 6 is fixed to prevent the nut 6 from loosening, thereby ensuring the connection strength of the power tower.

[0034] The outer surfaces of the support rod 2 and the reinforcing rod 3 are both fixedly connected with an isolation pad, the outer surface of the isolation pad is wrapped with a heat conductive sheet 9, the outer surface of the heat conductive sheet 9 is wrapped with a heat absorbing sheet 8, the ends of the support rod 2 and the reinforcing rod 3 are both fixedly connected with a heat transfer sheet, and the heat conductive sheet 9 is connected to the heat transfer sheet; the outer surface of the shock-absorbing isolation part 1 is alternately provided with a heat conductive sheet 24 and a heat absorbing sheet 25, and the threaded column 4 is located at the end of the heat conductive sheet 24. It can be seen from the above description that when the support rod 2 and the reinforcing rod 3 are connected to the shock-absorbing isolation part 1 The heat transfer sheet and the heat conductive sheet 24 are in contact, and the heat absorbing sheet 1 8 and the heat absorbing sheet 2 25 can absorb heat, and the heat can be transferred between the heat conductive sheet 1 9 and the heat conductive sheet 2 24 through the heat transfer sheet, so that when snow or ice accumulates on the special-shaped frame structure, the heat absorbing sheet not blocked by snow or ice can absorb heat and transfer the heat to the part blocked by snow or ice, accelerating the melting of snow or ice and reducing the load of the power tower. In addition, the isolation pad and the wrapping sleeve can reduce the impact of the external environment on the special-shaped frame structure. The heat conductive sheet 1 9, the heat conductive sheet 24 and the heat transfer sheet can be made of thermal conductive silicone, and the heat absorbing sheet 1 8 and the heat absorbing sheet 25 can be made of black epoxy resin.

[0035] In some embodiments of the present application, the special-shaped frame structure is as shown in the accompanying drawings of the specification, and the special-shaped frame structure can be applied to a human-shaped power tower.

[0036] To sum up: when the high-strength power tower special-shaped frame structure is in use, the setting of the shock-absorbing isolation part 1 can reduce the impact of vibration on other parts of the special-shaped frame, thereby improving the stability of the power tower using the special-shaped frame; through the setting of the connecting structure, the position of the nut 6 can be limited by the positioning block 16 to prevent the nut 6 from loosening, thereby improving the connection strength of the special-shaped frame, and when snow or ice is accumulated on the special-shaped frame structure, the heat-absorbing sheet that is not blocked by the snow or ice can absorb heat and transfer the heat to the part blocked by the snow or ice, thereby accelerating the melting of snow or ice and reducing the load on the power tower, and the isolation pad and the wrapping sleeve can reduce the impact of the external environment on the special-shaped frame structure.
