Description

Protective device for suspension cables of a wind power generating set

Technical field:

The utility model relates to a cable protection device for a wind power generating set, in particular to a protection device for a suspension cable at an upper section inside a tower tube of a wind power generating set.

Background technique:

During the operation of the wind turbine, the nose of the wind turbine must always face the wind direction. As the wind direction changes, the nose must rotate at any time. Therefore, the power cables and signal cables from the nose to the bottom of the tower must have One section is suspended from the centerline of the tower so that the individual cables can be twisted at an angle. Generally, the height of the tower is more than 50 meters. The blowing force of the wind will cause the tower and the engine room to swing back and forth, thereby driving the suspension cable to swing violently in the tower, and even collide with the tower, which will damage the cable. In order to avoid the large swing of the suspension cable, now The general solution is to install a cable protection device in the tower to limit the suspension cables to a smaller range. However, this kind of cable protection device is easy to cause wear and tear on the cable. After a long time, the cable insulation layer may even be worn out, causing a short circuit fault and threatening the personal safety of the on-site operation and maintenance personnel. Therefore, the existing cable protection device has disadvantages such as low safety, easy to cause cable wear, and additional protective rubber on the cable.

Invention content:

The purpose of the utility model is to overcome the disadvantages of the existing wind power generation set suspension cable protection device, such as low safety, easy to cause cable wear, and the need to attach protective rubber to the cable, and provide a convenient installation, higher safety, and simple structure. Wind turbine suspension cable protection device.

The utility model provides a suspension cable protection device for a wind power generating set, which includes a retaining ring and a rubber pad, and the rubber pad is fixed on the inner wall of the retaining ring. The feature is that the retaining ring is composed of two semicircular parts, Each semicircular portion of the retaining ring is composed of a mounting ear and a retaining ring, and the inner upper and lower edges of the cross section of the retaining ring are arc-shaped.

The mounting ears are located on both sides of the retaining ring; there are bolt holes in the middle of the mounting ears; the mounting ears can be completely symmetrical on both sides, and the mounting ears can also be hinge structures on one side and middle bolts on the other side hole structure. The retainer is a semicircular upper and lower edge arc-shaped eversion structure. The rubber pad can be a rectangular rubber pad; the rubber pad can also be a rubber pad adapted to the inner wall of the retainer.

The utility model has the advantages of extremely simple structure, scientific and reasonable design, safety, firmness and reliability, no abrasion to the cables, and is an ideal protection device for the suspension cables of the wind power generating set.

Detailed ways:

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

With reference to Fig. 1, the utility model comprises mounting ear 1, retaining ring 2, rubber pad 3, bolt 4.

Referring to Fig. 2 and Fig. 3, the retaining ring is composed of two completely symmetrical parts, and is fixed on the central axis of the tower of the wind power generating set by bolts 4 . Apply industrial glue between the rubber pad 3 and the retainer 2, and fasten it firmly, or fix the rubber pad 3 and the retainer 2 with screws, or integrally roll the rubber pad 3 and the retainer 2.

Referring to FIG. 4 , the retainer 2 adopts an arc-shaped and smooth eversion structure on the upper and lower edges.

When the utility model is in use, the retaining ring is installed on the fixed bracket on the ladder of the wind power generating set through the bolt 4, and the two symmetrical parts of the retaining ring are buckled together, and the suspension cable is buckled in the middle of the circular retaining ring. Long-term vibration causes the cable retaining ring to become loose, and the mounting bolt 4 is fixed with anti-skid nuts.

When using the utility model, the site needs to install the ladder and the cable retaining ring mounting bracket attached to the ladder in advance, and then the two parts of the cable retaining ring are buckled and installed on the fixed bracket in turn.

After the utility model is installed, when the suspension cable swings, due to the existence of the device, the suspension cable only swings in a small range, and the swing range of the cable is very small, and the buffering effect of the rubber pad 3 is also provided. Greatly reduced. At the same time, the retaining ring 2 adopts an edge valgus structure, so that sharper parts such as edges and corners of the cable retaining ring will not touch the cables, thereby reducing the abrasion of the cables to the greatest extent.

The utility model also has another embodiment, one of the two installation ears 1 of the utility model can be made into a hinge form, and the two parts of the utility model are connected together through the hinge.

The utility model also has another embodiment, the rubber gasket 3 can be a rubber ring adapted to the shape of the inner wall of the retainer 2, and surrounds the entire inner wall of the retainer 2.

Another embodiment of the utility model is that, in addition to using metal materials, the retaining ring can also use other materials, including hard plastic, rubber and resin, etc. In this case, the rubber pad 3 can not be installed.

The inside shape of the cross-section of the retaining ring of the utility model can be arc, semi-ellipse or other suitable shapes, and any equivalent changes will fall within the scope of protection of the utility model.
