Description

Technical Field

[0001] The utility model relates to the field of wind power equipment, in particular to a fixing device for cables of a wind power tower barrel. Background Technique

[0002] A wind power tower barrel refers to the tower pole of a wind turbine. The inside of the tower barrel is hollow for cables to pass through, and the cables are fixed to the inner wall of the tower barrel through cable clamps.

[0003] In the prior art, since the tower barrel is manufactured and installed in a wind farm, it is no longer possible to use welding to fix the cable clamp, and the too-thin tower barrel wall does not allow welding either. For reasons such as reducing the weight of the tower barrel, nail guns are usually used to fix the cable clamp. Under the continuous impact of long-term use and cable shaking, the nail guns will break and fall off, resulting in the cable becoming loose and losing restraint, posing a great safety hazard.

[0031] The principles and features of the present utility model will be described below with reference to the attached drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0032] Embodiment 1

[0033] As Figures 1 to 3 shown, a fixing device for a wind power tower barrel cable includes a plurality of tower barrel sections 1. A first cable clamp 2 is fixedly arranged at the top end inside the tower barrel section 1. A plurality of second cable clamps 3 are sequentially arranged on the inner wall of the tower barrel section 1 from top to bottom. The second cable clamps 3 are all installed on the inner wall of the tower barrel section 1 through magnetic parts. The second cable clamps 3 are sequentially connected by steel cables. The second cable clamp 3 at the uppermost position is connected to the first cable clamp 2 by a steel cable.

[0034] The beneficial effects of this embodiment are as follows: The first cable clamp 2 and the second cable clamps 3 are sequentially connected by steel cables, and the magnetic parts are used to provide a supporting force, which improves the stress situation, avoids the fracture and detachment of the installation position after the cable clamp is stressed for a long time, prolongs the service life, and reduces the maintenance cost; when facing the inertia of cable shaking, the magnetic parts also have the effect of slipping to eliminate the impact force.

[0035] Specifically, in this embodiment, the wind power tower barrel is composed of a plurality of tower barrel sections 1 welded in sequence. The top and bottom of the inner side of the tower barrel section 1 are flange plates, and are anchored to the flange plates of the adjacent tower barrel sections 1 by bolts. A plurality of welding columns are pre-welded on the inner side during the manufacture of the tower barrel section 1. The first cable clamp 2 is fixedly installed on the welding column. The second cable clamp 3 is fixedly installed on the inner wall of the tower barrel section 1 through a magnetic part. Both the first cable clamp 2 and the second cable clamp 3 include a cable rack, and the cable is fixed through the cable rack;

[0036] Then, the first cable clamp 2 and a plurality of second cable clamps 3 are sequentially connected by steel cables, and the weight of the cable is shared on the first cable clamp 2 and a plurality of magnetic parts, and the overall stress effect is better, avoiding the fracture of the installation position.

[0037] In this embodiment, the cable can be a complete one from top to bottom, and both the first cable clamp 2 and the second cable clamp 3 are connected to this cable.

[0038] As an alternative technical solution of this embodiment, multiple cables can also be provided. The first cable clamp 2 is connected to the first second cable clamp 3 below through one cable, and the second cable clamps 3 below are sequentially connected to each other in pairs through new cables.

[0039] Embodiment 2

[0040] As Figure 3 shown, preferably, on the basis of Embodiment 1, the magnetic part includes a magnetic steel 4 adsorbed on the inner wall of the tower barrel section 1, and the second cable clamp 3 is fixedly installed on the magnetic steel 4.

[0041] The beneficial effect of adopting the preferred solution in the above embodiment is that the magnetic steel 4 provides magnetic force, which is convenient for adsorbing and fixing the second cable clamp 3.

[0042] Preferably, a threaded hole is provided on the magnetic steel 4, and the second cable clamp 3 is fixedly installed in the threaded hole through a bolt.

[0043] The beneficial effect of adopting the preferred solution in the above embodiment is that the bolt fixes the second cable clamp 3, and the connection is firm and not easy to loosen.

[0044] Preferably, the magnetic steel 4 is a square brick-shaped magnetic steel.

[0045] The beneficial effect of adopting the preferred solution in the above embodiment is that the shape is regular, which is convenient for storage and use.

[0046] Specifically, in this embodiment, the magnetic steel 4 is a permanent magnet alloy. Magnetic steels 4 are installed at both ends of the second cable clamp 3 and anchored through bolts, and then the magnetic steels 4 are adsorbed on the inner wall of the tower barrel section 1. Compared with the conventional technology of anchoring the cable clamp by nail shooting, the magnetic steel 4 can not only share the weight of the cable, but also relieve the impact force when the cable sways left and right, has a longer service life, is convenient for maintenance, and is convenient for replacement.

[0047] On the basis of this embodiment, the magnetic steel 4 can be any one of neodymium iron boron magnetic steel, alnico magnetic steel and iron aluminum boron magnetic steel.

[0048] Embodiment 3

[0049] As Figure 1 shown, preferably, on the basis of Embodiments 1-2, the lowermost second cable clamp 3 is fixedly connected to the bottom flange position of the tower barrel section 1 through a cable.

[0050] The beneficial effects of adopting the preferred solution in the above embodiment are as follows: both the uppermost and lowermost ends of the steel cable are fixedly connected, reducing the sway of the second cable clamp 3 in the middle and achieving a stable connection.

[0051] Preferably, a plurality of transition bridges 5 are fixedly provided at the bottom flange position of the tower barrel section 1, and the second cable clamp 3 is fixedly connected to the transition bridge 5 through a steel cable.

[0052] The beneficial effects of adopting the preferred solution in the above embodiment are as follows: the steel cable is connected to the transition bridge 5, and it is not easily damaged or loosened.

[0053] Specifically, the top and bottom inside the tower barrel section 1 are flange plates, and the flange plates of two adjacent tower barrel sections 1 are anchored by bolts. During the manufacture of the tower barrel section 1, a number of welding columns are pre-welded inside. The transition bridge 5 is a rectangular steel frame and is located at the flange plate, which can support the cable to cross the flange plate. Both ends of the transition bridge 5 are fixedly connected to the welding columns on two tower barrel sections 1 respectively;

[0054] During the working process of the wind power tower barrel, vibrations and shakes will occur, and at the same time, the cable will be driven to sway left and right. Due to the large weight of the cable, its inertia is relatively large, which will cause frequent impacts on the installation position of the cable clamp and is extremely easy to break and fall off;

[0055] In this embodiment, the steel cable is a complete one from top to bottom. The upper end of the steel cable is fixedly installed on the first cable clamp 2, the lower end of the steel cable is fixedly installed at the lower flange position of the tower barrel section 1 or on the transition bridge 5, and several second cable clamps 3 are connected in the middle of the steel cable. By fixing both ends of the steel cable, the sway is reduced, and the impact force and slip received by the magnetic part are controlled within a certain range. The magnetic part will have a small amount of slip under the impact force, releasing the impact force, which is beneficial to reducing the load of the tower barrel and prolonging its service life.

[0056] As an alternative technical solution of this embodiment, multiple steel cables can also be provided. The first cable clamp 2 and the first second cable clamp 3 below are connected by a steel cable, and the second cable clamps 3 below are sequentially connected pairwise by new steel cables. One end of the steel cable is connected to the lowermost second cable clamp 3, and the other end of the steel cable is fixedly connected to the transition bridge 5, achieving the same technical effects as above.

[0059] The beneficial effects of adopting the preferred solution in the above embodiment are as follows: multiple first cable clamps 2 are used in combination to share the tension of the steel cable and avoid excessive concentration of force on a single first cable clamp 2.

[0060] Specifically, multiple first cable clamps 2 are fixedly connected to each other and are respectively fixed on the inner wall of the tower barrel section 1 through welding posts, sharing the weight of the cable and preventing the installation position of the first cable clamp 2 from being pulled and broken.

[0061] Embodiment 5

[0062] As Figure 3 shown, preferably, on the basis of Embodiments 1-4, a fixing member for fixing the steel cable is provided on the second cable clamp 3.

[0063] The beneficial effect of adopting the preferred solution in the above embodiment is that the fixing member is used to fix the second cable clamp 3 on the steel cable, sharing the weight of the cable and preventing the magnetic member from falling off.

[0064] Specifically, as Figure 3 shown, the fixing member can be two disc-shaped buckles. A steel cable groove is provided on the mating surface of the buckles. One buckle is fixedly connected to the second cable clamp 3, and the other buckle is anchored to the former buckle through a bolt;

[0065] As an alternative technical solution of this embodiment, the fixing member can also be a through hole provided on the second cable clamp 3, and the steel cable is fixed by passing through the through hole.

[0066] Embodiment 6

[0067] As Figure 2 shown, preferably, on the basis of Embodiments 1-5, an installation hole 6 is provided on the first cable clamp 2, and a shackle 7 is installed in the installation hole 6. One end of the steel cable is fixedly connected to the shackle 7.

[0068] The beneficial effect of adopting the preferred solution in the above embodiment is that the shackle 7 is used to connect the steel cable, which has strong bearing capacity and is convenient for disassembly.

[0069] Specifically, the shackle 7 is installed in the installation hole 6. One end of the steel cable passes through the U-shaped ring of the shackle 7 and then folds back towards the steel cable body direction, and is then fixed by a rope clamp, which is firmly connected and convenient for disassembly and replacement of the steel cable.

[0070] Embodiment 7

[0071] As Figure 1 shown, preferably, on the basis of Embodiments 1-6, a steel cable fixture is fixedly provided on the first cable clamp 2, and one end of the steel cable is fixedly connected to the steel cable fixture.

[0072] The beneficial effect of adopting the preferred solution in the above embodiment is that the steel cable fixture is used to fix the steel cable, and different steel cable fixtures can be selected according to the actual on-site situation, which is flexible to use.

[0073] In this embodiment, the steel cable fixture can be a rope clamp or a wire rope clip, and the steel cable is fixed after passing through the first cable clamp 2;

[0074] A groove may also be formed in the first cable clamp 2. After the steel cable is placed in the groove, it can be fixed by bolts. Other self-designed clamps can also be used as long as they can achieve the function of fixing the steel cable. This embodiment is not limited in this regard.
