[0021] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.
[0022] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Figures 1-4 The utility model relates to a device for fixing and preventing drooping of wind turbine generator box transformer cable, including the hoop 3 for fixing box transformer cable 7, hoop 3 includes two sets of semicircle ring 301 and connecting plate 304, both ends of semicircle ring 301 are connected with connecting plate 304, semicircle ring 301 is hinged between connecting plate 304, make semicircle ring 301 can rotate along the vertical direction.
[0023] Specifically, box transformer cable 7 diameter is thick, weight is big, length is long, texture is hard, when installing, only use bolt to fix cable head on the wiring rack on crossbeam 5, box transformer cable 7 itself does not have stable supporting structure, only then can appear drooping phenomenon due to dead weight.
[0024] When the device is used, the box transformer cable 7 is clamped by the hoop 3, and the box transformer cable 7 is fixed directly below the connection point of the wiring rack, so that the box transformer cable 7 forms a support through its own structure, thereby achieving the effect of preventing drooping.
[0025] Because the box transformer cable 7 itself is relatively hard, and the internal construction space of the box-type transformer station is limited, it is difficult for the construction personnel to manually adjust the position and shape of the box transformer cable 7, and the semicircle ring 301 is hinged with the connecting plate 304, so that when the construction personnel pulls the box transformer cable 7, the box transformer cable 7 does not need to be arranged in a completely horizontal and vertical state, but can be allowed to be in an inclined state as shown in the figure, thereby reducing the construction difficulty. Figure 3
[0026] After the box transformer cable 7 is fixed by using the hoop 3, the displacement and oblique swing of the box transformer cable 7 in the front-back and left-right directions can be effectively prevented, thereby maintaining a good self-supporting effect.
[0027] The semicircle ring 301 and the connecting plate 304 are provided with a rotating shaft 302 and a rotating shaft seat 303, the semicircle ring 301 is connected with the rotating shaft 302, the rotating shaft seat 303 is connected with the connecting plate 304, and the rotating shaft 302 and the rotating shaft seat 303 are rotatably connected. After the box transformer cable 7 is clamped by using the hoop 3, when the box transformer cable 7 is bent upward in the vertical direction and connected with the connection point, the two semicircle rings 301 can be adaptively rotated by a certain angle under the rotating action of the rotating shaft 302 and the rotating shaft seat 303, thereby reducing the construction difficulty.
[0028] The device further comprises a long bolt 2, and the connecting plate 304 is movably sleeved on the long bolt 2 along the axial direction of the long bolt 2.
[0029] The long bolt 2 is used to move the hoop 3 in the axial direction of the long bolt 2, adjust the distance between the box cable 7 and the side wall 5 and the bottom 6 of the box, and improve the stability of the device in supporting the box cable 7.
[0030] The long bolt 2 comprises a screw rod 201, a lower nut 202 and an upper nut 203 matched with the screw rod 201, and a connecting plate 304 sleeved on the screw rod 201, the lower nut 202 and the upper nut 203 are respectively located on the two sides of the connecting plate 304, the hoop 3 is fixed inside the box by using the screw rod 201, then the position of the hoop 3 on the screw rod 201 is adjusted by using the lower nut 202 and the upper nut 203, and finally the lower nut 202 and the upper nut 203 are tightened to clamp the hoop 3.
[0031] The base 1 is further included, the base 1 comprises a bottom plate 101, the lower nut 202 is connected with the bottom plate 101, the lower nut 202 is located between the bottom plate 101 and the connecting plate 304, the lower nut 202 and the upper nut 203 are respectively located on the two sides of the two connecting plates 304, and are used to adjust the position of the hoop 3 and clamp the two connecting plates 304.
[0032] The mounting hole 102 is processed on the bottom plate 101, and the device is fixed on the inner wall of the box by using the mounting bolt through the mounting hole 102.
[0033] The hoop 3 has two, and the two hoops 3 are located below the cross beam 4, and the specific position is as shown in Figure 3 The horizontal part and the vertical part of the box cable 7 are in the same vertical plane, thereby forming a self-supporting effect.
[0034] Working principle: when in use, the length of the box cable 7 is roughly adjusted according to the connecting point of the box cable 7 on the cross beam 4, then the two devices are respectively installed on the box side wall 5 below the connecting point and on the box bottom 6, so that the two devices and the connecting point are roughly in the same vertical plane;
[0035] Then, the semicircular ring 301 away from the bottom plate 101 of the two hoops 3 is respectively removed, then the box cable 7 is respectively passed between the two screw rods 201 of the two hoops 3, and then the cable head of the box cable 7 is tightly fixed on the connecting point of the wiring rack on the cross beam 4;
[0036] Next, the removed semicircular ring 301 is installed on the screw rod 201, and finally the position of the semicircular ring 301 is adjusted and the box cable 7 is clamped by tightening the lower nut 202 and the upper nut 203, so that the vertical part of the box cable 7 is perpendicular as much as possible, and the horizontal part of the box cable 7 is close to the box bottom 6 as much as possible, thereby making the box cable 7 form support through its own structure, and achieving the effect of preventing sagging.
