Description

Technical Field

[0001] The utility model relates to the technical field of fan blade transportation, in particular to a wind turbine blade transportation fixing seat. Background Art

[0002] The blades of wind turbines are very large, often tens of meters long or even longer, and usually have to be transported separately. Separate transportation makes transportation arrangements more flexible, and appropriate transportation methods and routes can be selected according to the characteristics of the blades to improve transportation efficiency and safety. The existing transportation method usually fixes the blades to the mounting base with straps, and the entire disassembly and assembly process is very convenient. However, this fixing method still has certain problems: if the straps are fixed very tightly and the blades are thin, the tight straps will squeeze the blades, causing them to deform. If the straps are tied loosely, the blades will shift and collide with the fixing base when transported to bumpy roads, thereby causing damage to the blades. Based on the above viewpoints, technicians in this field have proposed a wind turbine blade transportation fixing base to solve the above problems. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a wind turbine blade transportation fixing seat is proposed. The fixing seat provides elasticity through an elastic force supply spring, and the fixing belt can adapt to the fan surface by pulling the fixing belt. When transporting on a flat road, the fixing belt only presses the fan blades on the fixing seat, and the fan blades will not be deformed due to excessive tightening. The non-Newtonian fluid can change the supply elastic force of the fixing belt, effectively preventing the fan blades from being damaged due to displacement and collision when being transported on bumpy roads.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A wind turbine blade transport fixing seat, comprising an outer base and four damping shock absorbers, wherein the four damping shock absorbers are installed at the four corners of the upper side wall of the outer base, and a fixing assembly is installed on the top of the four damping shock absorbers, wherein the fixing assembly comprises a fixing seat, and a plurality of binding assemblies are arranged in the fixing seat, wherein the binding assembly comprises a non-Newtonian fluid storage tank, two connecting rings, two elastic force supply springs, two fixing plates, two outer sealing plates, two pull rods, two connecting plates and a fixing belt;

[0006] The non-Newtonian fluid storage tank is opened at the bottom of the fixed seat, the two connecting rings are fixed on both sides of the top of the non-Newtonian fluid storage tank, the two elastic supply springs are respectively fixed on the side wall of the connecting ring away from each other, the two fixing plates are respectively fixed on the other ends of the two elastic supply springs, the two outer sealing plates are respectively fixed on the top of the non-Newtonian fluid storage tank near the two ends, the two pull rods are respectively fixed on the side wall of the fixing plates away from each other, and the other ends of the two pull rods are arranged on the outside of the fixed seat, the two connecting plates are respectively fixed on the other ends of the pull rods, and the fixing belt is fixed on the two connecting plates and pressed tightly against the upper surface of the fixed seat.

[0007] Through the above technical solution, the fan is fixed to the fixing seat by a fixing belt, and the fixing belt provides elasticity through an elastic force supply spring. Since the surface of the fan blade is irregular, when the fan is fixed by the fixing belt, the fixing belt can be pulled to adapt to the surface of the fan. When transporting on a flat road, the fixing belt only presses the fan blades on the fixing seat, and the fan blades will not be deformed due to excessive tightening.

[0008] Furthermore, a bottom sealing sheet is slidably connected to the bottom of the non-Newtonian fluid storage tank, and the interior of the non-Newtonian fluid storage tank and between the non-Newtonian fluid storage tank and the two outer sealing sheets are filled with non-Newtonian fluid;

[0009] Through the above technical solution, the non-Newtonian fluid can change the supply elastic force of the fixing belt.

[0010] Furthermore, a fixed outer tube is fixedly connected to the upper end surface of the lower side wall of the outer base and is located directly below each non-Newtonian fluid storage tank, an inner spring is installed inside the fixed outer tube, and a push rod is limitedly slidably connected to the top of the inner side wall of the fixed outer tube;

[0011] Through the above technical solution, when the fixing seat is transported on a bumpy road section, the outer base compresses the damping shock absorber to reduce shock, and at the same time the push rod pushes the bottom sealing plate upward, thereby squeezing the non-Newtonian fluid in the non-Newtonian fluid storage tank through the bottom sealing plate. The non-Newtonian fluid becomes solid, and the two elastic supply springs cannot be extended or retracted, and the fixing belt loses its elasticity, effectively preventing the fan blades from being damaged due to displacement and collision when being transported on a bumpy road section.

[0012] Furthermore, tension rod grooves are provided at both sides of the upper side wall of the fixing seat, and a motor mounting frame is installed on the rear side wall of the fixing seat;

[0013] Through the above technical solution, the adjustment tension rod is installed through the tension rod groove.

[0014] Furthermore, a fixed belt adjustment assembly is installed in each of the two tension rod grooves, and the fixed belt adjustment assembly includes an adjustment tension rod, a transmission motor and two belt roller gears. The adjustment tension rod is installed in the tension rod groove through a bearing, and the transmission motor is installed at the front end of the motor mounting frame. Fixed belt rollers are fixed to the front ends of the two adjustment tension rods, and a motor gear is installed at the movable end of the adjustment tension rod. A belt roller gear is installed inside the motor mounting frame and on the left side of the motor gear, and the belt roller gear is meshed with the motor gear. A transmission belt roller is fixed to the front sides of the belt roller gear and the motor gear, and a connecting belt is sleeved on the fixed belt roller and the transmission belt roller on the left side and the fixed belt roller and the transmission belt roller on the right side.

[0015] Through the above technical solution, when the fan blades need to be loaded and unloaded, the adjusting tension rod drives the motor gear to rotate, and then drives the belt roller gear to rotate in the opposite direction. The two mutually counter-rotating transmission belt rollers drive the two connecting belts to rotate, and then drive the two adjusting tension rods to open. The opened adjusting tension rod stretches the fixed belt, which greatly facilitates the operator to disassemble the fan blades.

[0016] The utility model has the following beneficial effects:

[0017] 1. In the utility model, elasticity is provided by an elastic supply spring, which can make the fixing belt adapt to the surface of the fan by pulling the fixing belt. When transporting on a flat road, the fixing belt only presses the fan blades on the fixing seat, and will not cause the fan blades to deform due to excessive tightening. The non-Newtonian fluid can change the supply elastic force of the fixing belt, effectively preventing the fan blades from being damaged due to displacement and collision when transporting on bumpy roads.

[0018] 2. In the utility model, when the fan blades need to be loaded and unloaded, the adjusting tension rod drives the motor gear to rotate, thereby driving the belt roller gear to rotate in the opposite direction, and the two mutually counter-rotating transmission belt rollers drive the two connecting belts to rotate, thereby driving the two adjusting tension rods to open, and the opened adjusting tension rods stretch the fixing belts, which greatly facilitates the operator to disassemble the fan blades.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example:

[0030] Reference Figure 1-4 The utility model provides an embodiment of a wind turbine blade transport fixing seat, comprising an outer base 1 and four damping shock absorbers 5, the four damping shock absorbers 5 are installed at the four corners of the upper side wall of the outer base 1, and a fixing component 2 is installed on the top of the four damping shock absorbers 5, the fixing component 2 comprises a fixing seat 21, and a plurality of binding components 3 are arranged in the fixing seat 21, and the binding component 3 comprises a non-Newtonian fluid storage tank 35, two connecting rings 36, two elastic supply springs 37, two fixing plates 38, two outer sealing plates 39, two pull rods 310, two connecting plates 311 and a fixing belt 312.

[0031] The non-Newtonian fluid storage tank 35 is provided at the bottom of the fixed seat 21, two connecting rings 36 are fixed on both sides of the top of the non-Newtonian fluid storage tank 35, two elastic supply springs 37 are respectively fixed on the side walls of the connecting rings 36 away from each other, two fixing plates 38 are respectively fixed on the other ends of the two elastic supply springs 37, two outer sealing plates 39 are respectively fixed on the top of the non-Newtonian fluid storage tank 35 near the two ends, two pull rods 310 are respectively fixed on the side walls of the fixing plates 38 away from each other, and the other ends of the two pull rods 310 are arranged outside the fixed seat 21, and the two connecting plates 311 are respectively fixed to the other end of the pull rod 310, and the fixing belt 312 is fixed on the two connecting pieces 311 and pressed tightly against the upper surface of the fixing seat 21. The fan is fixed on the fixing seat 21 by the fixing belt 312. The fixing belt 312 provides elasticity through the elastic force supply spring 37. Since the surface of the fan blade is irregular, when the fan is fixed by the fixing belt 312, the fixing belt 312 can be pulled to adapt to the surface of the fan. When transporting on a flat road, the fixing belt 312 only presses the fan blade on the fixing seat 21, and will not cause the fan blade to be deformed due to excessive tightening.

[0032] The bottom of the non-Newtonian fluid storage tank 35 is limitedly slidably connected with a bottom sealing sheet 34. The interior of the non-Newtonian fluid storage tank 35 and between the non-Newtonian fluid storage tank 35 and the two outer sealing sheets 39 are filled with non-Newtonian fluid. The non-Newtonian fluid can change the supply elastic force of the fixed belt 312. The upper end surface of the lower side wall of the outer base 1 and directly below each non-Newtonian fluid storage tank 35 are fixedly connected with a fixed outer tube 31. The interior of the fixed outer tube 31 is installed with an inner spring 32. The top of the inner side wall of the fixed outer tube 31 is limitedly slidably connected. A push rod 33 is connected. When the wind turbine blade transport fixing seat, which is a transport component, is transported on a bumpy road section, the outer base 1 compresses the damping shock absorber 5 for shock absorption. At the same time, the push rod 33 pushes the bottom sealing plate 34 upward, and then squeezes the non-Newtonian fluid in the non-Newtonian fluid storage tank 35 through the bottom sealing plate 34. The non-Newtonian fluid becomes solid, and the two elastic supply springs 37 cannot be extended or retracted, and the fixing belt 312 loses its elasticity, which effectively prevents the fan blades from being damaged due to displacement and collision when being transported on a bumpy road section.

[0033] Tension rod grooves 22 are provided on both sides of the upper side wall of the fixed seat 21, a motor mounting frame 23 is installed on the rear side wall of the fixed seat 21, an adjusting tension rod 42 is installed through the tension rod grooves 22, and a fixed belt adjustment component 4 is installed in each of the two tension rod grooves 22. The fixed belt adjustment component 4 includes an adjusting tension rod 42, a transmission motor 41 and two belt roller gears 43. The adjusting tension rod 42 is installed in the tension rod groove 22 through a bearing, and the transmission motor 41 is installed at the front end of the motor mounting frame 23. Fixed belt rollers 46 are fixed to the front ends of the two adjusting tension rods 42, and a motor gear 47 is installed at the movable end of the adjusting tension rod 42. A belt roller 46 is installed inside the motor mounting frame 23 and on the left side of the motor gear 47. Belt roller gear 43, belt roller gear 43 is meshed with motor gear 47, and transmission belt roller 44 is fixed on the front side of belt roller gear 43 and motor gear 47, and the fixed belt roller 46 and transmission belt roller 44 on the left side and the fixed belt roller 46 and transmission belt roller 44 on the right side are all sleeved with connecting belt 45. When it is necessary to load and unload the fan blades, the adjusting stretch rod 42 drives the motor gear 47 to rotate, and then drives the belt roller gear 43 to rotate in the opposite direction. The two mutually counter-rotating transmission belt rollers 44 drive the two connecting belts 45 to rotate, and then drives the two adjusting stretch rods 42 to open. The opened adjusting stretch rod 42 stretches the fixed belt 312, which greatly facilitates the operator to disassemble the fan blades.

[0034] Working principle: The fan is fixed on the fixing seat 21 by the fixing belt 312. The fixing belt 312 provides elasticity through the elastic force supply spring 37. Since the surface of the fan blade is irregular, when the fan is fixed by the fixing belt 312, the fixing belt 312 can be pulled to adapt to the surface of the fan. When transported on a flat road, the fixing belt 312 only presses the fan blade on the fixing seat 21, and will not cause the fan blade to deform due to excessive tightening. When the wind turbine blade transport fixing seat is transported on a bumpy road, the outer base 1 compresses the damping shock absorber 5 for shock absorption, and at the same time the push rod 33 pushes the bottom sealing sheet 34 upward. Then, the non-Newtonian fluid in the non-Newtonian fluid storage tank 35 is squeezed through the bottom sealing sheet 34, and the non-Newtonian fluid becomes solid, so that the two elastic supply springs 37 cannot be extended or retracted, and the fixing belt 312 loses its elasticity, effectively preventing the fan blades from being damaged due to displacement and collision when being transported on bumpy roads. When the fan blades need to be loaded and unloaded, the adjusting tension rod 42 drives the motor gear 47 to rotate, and then drives the belt roller gear 43 to rotate in the opposite direction. The two mutually counter-rotating transmission belt rollers 44 drive the two connecting belts 45 to rotate, and then drive the two adjusting tension rods 42 to open. The opened adjusting tension rod 42 stretches the fixing belt 312, which greatly facilitates the operator to disassemble the fan blades.
