Description

Technical Field

[0001] The utility model relates to the field of wind power generator sets, in particular to a driver cable fixing structure. Background Art

[0002] The pitch drive is the core component of the pitch system. Its main function is to provide signals. In the operation of the pitch drive, the pitch encoder is a sensor device used to measure the rotation angle and speed of the blades and control the power output of the wind turbine, thereby maximizing the power generation efficiency of the wind farm and ensuring the efficient and stable operation of the wind farm. Due to the wind power generation environment, the unit will have a certain vibration during operation. The encoder line is a plug-in type. The unit is prone to loose wiring during long-term vibration operation, resulting in fault shutdown, thereby increasing the frequency of tower access, increasing workload and operation and maintenance costs.

[0003] In addition, in order to prevent the external circuit voltage from interfering with the communication signal, the method of stripping off part of the encoder wire is often used. This can reduce interference by grounding, but the exposed wires are prone to leakage and lack of protection can easily cause damage.

[0004] Currently, in order to achieve the purpose of cable fixing, most of the cables on the market use screws to lock the wire clamping plate. Although this method is simple, it is easy to damage the cable and needs to be improved.

[0005] For example, the invention patent with publication number CN104132188A discloses a wire fixer, which uses two buckles and protrusions to hold the cable, and uses a connector to hold the two cables, and then uses a wall nail to install the cable on the wall. In this invention, the connector is fixed by a wall nail, which is inconvenient to implement in other occasions and cannot be grounded, which has the effect of reducing communication signal interference. Utility Model Content

[0006] The utility model aims to overcome the shortcomings of the prior art and provide a frequency converter delay improvement circuit.

[0007] The purpose of the utility model is achieved through the following technical solutions:

[0008] The drive cable fixing structure comprises a fixing bracket for carrying the cable, the fixing bracket is provided with a through groove, and the through groove is located on both sides of the cable; a shielding bracket can also be plugged into the fixing bracket, and the shielding bracket comprises a horizontal end and a first vertical end and a second vertical end arranged at both ends thereof, and the first vertical end and the second vertical end can extend through the through groove and be placed below it; a sliding groove is provided on the first vertical end, and a limit plate is slidably provided on the sliding groove, the limit plate comprises an upper surface, a lower surface and a locking end, the limit plate can be locked on the sliding groove by a locking member, and the second vertical end comprises an outer wall and an inner wall, a limit member is fixed on the inner wall, and the other end of the limit plate can be mounted on the limit member so that the lower surface of the horizontal end is always in close contact with the cable.

[0009] Preferably, an opening is provided at one end of the limit plate close to the first vertical end, and the length of the opening is greater than or equal to the width of the first vertical end.

[0014] Preferably, both sides of the horizontal end are wrapped with an elastic layer.

[0015] Preferably, the elastic layer is made of rubber.

[0016] The beneficial effects of the utility model are mainly reflected in:

After that, the longer bottom edge of the limit plate fits the top edge of the limit block. At this time, the lower surface of the limit plate is placed on the top edge, and the other end of the limit plate is fixed by the locking piece, so that the limit plate cannot move downward, thereby fixing the position of the limit plate, and then fixing the position of the cable. When the cable space is too small, the cable will cause a backlog on the limit plate. The limit plate has a certain flexibility and will be squeezed to the next limit block to automatically adjust to a suitable position; the overall structure is simple and easy to assemble;

[0024] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments are not limited to the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0026] like Figure 1-Figure 2As shown, the utility model discloses a driver cable fixing structure, including a fixing bracket 1 for carrying a cable 100, wherein the fixing bracket 1 is fixed to a driver housing 200 by spot welding. The fixing bracket 1 is provided with a through slot 11, and the through slot 11 is located on both sides of the cable 100; a shielding bracket 2 can also be plugged into the fixing bracket 1, and the shielding bracket 2 includes a horizontal end 21 and a first vertical end 22 and a second vertical end 23 arranged at both ends thereof, and the first vertical end 22 and the second vertical end 23 can extend through the through slot 11 and be placed below it. The distance between the two through slots 11 is equal to the width of the horizontal end 21, so the shielding bracket 2 can be conveniently plugged into the fixing bracket 1 through the through slot 11.

[0027] The two sides of the horizontal end 21 are wrapped with elastic layers made of rubber. Since the unit will vibrate during operation, the inside of the shielding bracket 2 will inevitably collide with the cable. The elastic layer can play a buffering role to avoid wear and tear on the cable during long-term operation. The elastic layer made of rubber can also play an insulating role to avoid electric shock.

[0028] like Figure 2 As shown, a slide groove 3 is provided on the first vertical end 22, a limit plate 4 is slidably provided on the slide groove 3, and the limit plate 4 can be locked on the slide groove 3 by a locking member 5. A limit member 6 is fixed on the inner wall of the second vertical end 23, the length of the upper surface of the limit block 4 is less than the distance between the limit block 61 and the first vertical end 22, and the length of the lower surface of the limit block 4 is greater than the distance between the limit block 61 and the first vertical end 22. The limit member 6 includes at least one group of limit blocks 61 fixed on the inner wall 232, the cross section of the limit block 61 is a right triangle, and the upper surface thereof is a horizontal plane.

[0029] The limiting member 6 includes a group of limiting blocks 61, which are vertically arranged on the inner wall of the second vertical end 23, so as to cooperate with the limiting plate to adapt to cables of various sizes. The limiting blocks are in the shape of a right-angled triangle, one of which is in contact with the inner wall 232, and the other is used to place the bottom of the limiting plate 4 to play a supporting role.

[0030] The end of the limiting plate 4 close to the inner wall 232 is provided with a triangular block 43 integrally formed therewith. The cross section of the triangular block 43 is a right triangle, and its lower surface is a horizontal plane. The inclined surface of the triangular block 43 is parallel to the inclined surface of the limiting block 61.

[0031] The triangle block 43 and the limit plate 4 are combined to form a right-angled trapezoid. When the limit plate 4 moves upward, since the inclined surface of the triangle block 43 is parallel to the inclined surface of the limit block 61, the limit plate 4 can be easily moved to the top of the limit block after a slight tilt. After that, the longer bottom edge of the limit plate 4 fits with the top edge 611 of the limit block 61. At this time, the lower surface 46 of the limit plate 4, that is, the longer end of the trapezoid is placed on the top edge 611. At this time, the other end of the limit plate 4 is fixed by the locking member 5, so that the limit plate 4 cannot move downward, and the position of the limit plate is fixed, and then the position of the cable is fixed, so that the lower surface 46 of the horizontal end 21 is always in close contact with the cable 100. When the cable space is too small, the cable will cause a backlog on the limit plate 4. The limit plate 4 has a certain flexibility and will be squeezed to the next limit block 61, and automatically adjust to a suitable position. The overall structure is simple and easy to assemble.

[0032] In this embodiment, the cable fixed by the cable fixing structure is the cable of the encoder, but by adjusting the position of the limiting plate so that it is installed with different limiting members, the size of the internal space can be adjusted to adapt to other types of cables.

[0033] like Figure 3 As shown, an opening 41 is provided at one end of the limit plate 4 close to the first vertical end 22, and the length of the opening 41 is greater than or equal to the width of the first vertical end 22. A locking hole 42 is also provided on the limit plate 4, and the locking member 5 can penetrate the locking hole 42 to lock the limit plate 4 on the first vertical end 22. The locking member 5 at least includes a bolt 51 and a nut 52 matched therewith, and the bolt 51 sequentially penetrates the locking hole 42 and the slide slot 3 and is screwed to the nut 52.

[0034] In the present invention, an opening 41 having a size matching that of the first vertical end 22 is reserved on the limit plate 4 for connecting the limit plate 4 to the first vertical end 22, thereby saving space. The limit plate 4 can be simply and effectively locked to the first vertical end 22 using bolts and nuts, and the limit plate 4 can be limited to move up and down in the slide slot, which is convenient for inspection and maintenance.

[0035] The working process of the utility model is briefly described below:

[0036] First, place the cable 100 flat on the fixed bracket 1, between the two through grooves 11, and then insert the shielding bracket 2 into the through groove 11, so that the horizontal end 21 of the shielding bracket 2 is in close contact with the top of the cable 100, and then push the triangular block 43 of the limiting plate 4 upward to the appropriate limiting block 61, so that the lower surface 44 is in close contact with the bottom of the cable 100, and then adjust the position of the locking end 45 of the limiting plate 4 by moving the locking piece 5, so that the limiting plate 4 is parallel to the horizontal end 21, and finally tighten the bolt 51 and the nut 52 of the locking end 5 to complete the fixation of the cable 100.

[0037] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0038] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model. They are not intended to limit the protection scope of the utility model. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.
