In one aspect of the present disclosure, a wind power generation unit is provided, the wind power generation unit includes a tower and a nacelle, the nacelle is supported on the tower, an intra-cabin cable is disposed in the nacelle in order to satisfy circuit transmission of the wind power generation unit, and the cable is also fixedly disposed on a tower wall of the tower. In the operation process of the wind generating set, because the wind direction changes in real time, in order to have a proper windward side, the impeller needs to yaw, so that the cable is easy to wear, and the service life of the cable is further influenced. In addition, during the operation of the wind generating set, under the action of external wind force, the nacelle or the tower shakes due to impact, and at the moment, the cable is worn due to shaking.
In order to reduce wear and entanglement of cables, the present disclosure provides a cable protection device that may be used to space multiple cables to avoid wear between the cables, which may increase the service life of the cables. In other words, the cable protection device in this embodiment can be used as a cable spacer to keep a plurality of cables in a relatively fixed position, so that wear between the cables can be avoided and the service life of the cables can be improved.
In addition, the cable protection device provided by the embodiment has the function of preventing the cable from twisting and winding, so as to avoid the situation that the cable is damaged due to excessive twisting caused by winding for a plurality of turns in the operation process.

So set up, when wind generating set does not need driftage, cable protection device can be in the circular telegram state to make first magnetism absorb the piece and absorb the piece 30 mutually with the second magnetism, torsion member 20 firmly connects on fixed barrel 10, so that the cable is tied up on fixed barrel 10, and the cable can not rock under this state, consequently can avoid wearing and tearing between the cable. When the wind generating set needs to yaw, the cable protection device can be powered off, at the moment, the first magnetic absorption part and the second magnetic absorption part 30 are separated, and the torsion part 20 can swing or rotate freely in the fixed cylinder 10, so that the cable can yaw along with the wind generating set, and the cable is prevented from being twisted excessively and wound together in the yaw process of the wind generating set.
With continued reference to fig. 1 and 2, in the present embodiment, the torsion member 20 is a ring body, the second magnetic attraction member 30 is disposed outside the ring body of the torsion member 20, and the first magnetic attraction member is disposed inside the fixing cylinder 10 and opposite to the second magnetic attraction member 30. So set up, first magnetism is absorbed the accessory and second magnetism is absorbed the accessory and can be close to the setting mutually to when cable protection device is in the energized state, the magnetism attraction between first magnetism is absorbed the accessory and the second magnetism is absorbed the accessory and can stably support torsion member 20, avoids torsion member 20 to fix barrel 10 unexpected slip relatively. Alternatively, the fixed cylinder 10 may be a cylinder, and the torsion member 20 may be a torus, so as to avoid forming a sharp lobe, and thus, in the process of rotating the torsion member 20 relative to the fixed cylinder 10, the sharp portion may be prevented from being scratched, thereby improving the service life of the cable protection device.
In this embodiment, in order to further improve the service life of the cable protection device, the first magnetic attraction piece is pre-buried inside the fixed cylinder 10, so that the first magnetic attraction piece is stably connected to the fixed cylinder 10, and the safety and reliability of the cable protection device are further improved, but not limited to this, the first magnetic attraction piece is fixed on the inner wall of the fixed cylinder 10.
In order to further improve the safety and reliability of the cable protection device, the first magnetic absorption member may not protrude from the inner wall surface of the fixed cylinder 10, so as to keep the inner wall of the fixed cylinder 10 flat and avoid accidental collision.

In this embodiment, the ferromagnetic metal may be iron, nickel or cobalt. Of course, the first magnetic attraction member may also be a non-metallic magnetic material, such as ferrite.
As an example, the second magnetic adsorbing member 30 has an arc-shaped attaching surface capable of attaching to the inner wall of the fixed cylinder 10, and the second magnetic adsorbing member 30 is a circular arc segment. In this way, the second magnetic absorbing member 30 is non-annular, so that the cable protection device is prevented from generating uniform absorbing force in the whole circumferential direction of the torsion member 20 after being electrified, and the torsion member 20 is balanced in stress and cannot approach the fixed cylinder 10 at one side.
In this embodiment, the second magnetic absorbing members 30 may be plural, and the plural second magnetic absorbing members 30 may be disposed on a single side of the torsion member 20, and when the cable protection device is powered on, the second magnetic absorbing members 30 are attracted to the fixed cylinder 10 due to power on, so that the torsion member 20 is forced to move in unbalanced manner, specifically, the torsion member 20 approaches to the fixed cylinder 10 and is attached to a side of the fixed cylinder 10 near to the second magnetic absorbing members 30.
In this embodiment, in order to reduce the weight of the cable protection device, the torsion member 20 may be a non-metal member, but is not limited thereto.

As an example, a receiving hole for receiving a displacement sensor is provided at a certain position of the second magnetic adsorbing member 30, and the displacement sensor may be disposed in the receiving hole, and when the displacement sensor monitors a first predetermined value in a state that the second magnetic adsorbing member 30 is adsorbed to the fixed cylinder 10, and the actual ranging value is greater than the first predetermined value, it may be considered that the second magnetic adsorbing member 30 is not attached to the fixed cylinder 10, that is, the second magnetic adsorbing member 30 is separated from the first magnetic adsorbing member. Alternatively, the first predetermined value may be 0, or may be a predetermined range, but is not limited thereto.
Similarly, in the case where the cable protection device includes a pressure sensor, a certain position of the second magnetic absorption member 30 is provided with a receiving hole for receiving the pressure sensor, and the pressure sensor may be disposed in the receiving hole. In the case where the second magnetic adsorbing element 30 is adsorbed to the first magnetic adsorbing element, the pressure sensor is pressed to monitor the second predetermined value due to the electromagnetic force, and when the actual pressure measurement value is smaller than the second predetermined value, the second magnetic adsorbing element 30 is separated from the first magnetic adsorbing element. As an example, in the case that the second magnetic absorption member 30 is separated from the first magnetic absorption member, the pressure sensor is not pressed, and the monitoring result may be 0, but not limited thereto. Alternatively, the second predetermined value may be a single value, or may be a predetermined range, but is not limited thereto.
