Detailed Description

In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined below to clearly and completely describe the technical solution of the embodiments of the present invention. It is to be understood that the embodiments described are some, not all embodiments of the invention. All other embodiments, which can be derived from the description of the embodiments of the present invention by a person skilled in the art, are within the scope of the present invention.

As shown in figures 1 to 6 of the drawings,

the utility model provides an oil-immersed transformer coil dip coating groove structure, including be the body 1 of cover form and communicate in the discharge pipe 2 of 1 bottom of body, be provided with control valve 3 on the discharge pipe 2, the inner wall of body 1 is improved level and is provided with annular lock ring 4, be provided with on the lock ring 4 and be annular carriage 5, parallel arrangement has a plurality of bracing piece 6, every on the inner wall of carriage 5 the both ends of bracing piece 6 all with carriage 5 is connected, be provided with on the inner wall of body 1 and be used for fixing the positioning mechanism of carriage 5 angle works as positioning mechanism is fixed during carriage 5, carriage 5 is the slope form, just the bottom of carriage 5 contradict in one side of lock ring 4 and the inner wall of body 1.

The support rod 6 is cylindrical. The carriage 5 is the rectangle, the length of bracing piece 6 equals carriage 5's minor face length, works as when carriage 5 is the slope form, one side long limit of carriage 5 contradicts in lock ring 4. A plurality of liquid falling holes 7 are vertically arranged through the support ring 4.

Positioning mechanism including set up in first connecting seat 8 on the 1 inner wall of body and the first coupler body, connecting cable and the second coupler body that connect gradually, be provided with second connecting seat 9 on the inner wall of 5 free sides of carriage, first connecting seat 8 with all offer on the second connecting seat 9 and be used for first coupler body with the hole that the second coupler body passed. The inner wall of the body 1 is further provided with a third connecting seat 10, the third connecting seat 10 is provided with holes for the first hook body and the second hook body to pass through, and when the first hook body is connected with the first connecting seat 8 and the second hook body is connected with the third connecting seat 10, the connecting cable is in a tensioning state.

The body 1 including the supporting part 1a and with the communicating outflow 1b in supporting part 1a bottom, the cross section of supporting part 1a is the rectangle, just the lock ring 4 connect in the inner wall of supporting part 1a, outflow 1b is big-end-up's tubaeform, discharge pipe 2 communicate in the bottom of outflow 1 b. The discharge pipe 2 is L-shaped, the top of the discharge pipe 2 is vertically connected with the outer flow part 1b, and the bottom of the discharge pipe is horizontally positioned at the outer side of the supporting part 1 a. The top of the body 1 is provided with a sealing cover 11, and the top of the sealing cover 11 is provided with an inverted U-shaped operating handle 12.

When the coil is subjected to paint dipping, the coil is placed in the body 1 filled with the varnish and is positioned on the support rod 6; after the dip coating is finished, the coil is taken out, the control valve 3 is opened, the varnish in the body 1 is discharged outwards through the discharge pipe 2, after most of the varnish is discharged, the support frame 5 is rotated upwards, the angle of the support frame 5 is fixed through the positioning mechanism, and at the moment, because the support frame 5 is in an inclined state, the varnish adhered to the support frame 5 and the support rod 6 can flow downwards in an accelerated manner and finally flows out to the outside; the outward flow speed of the varnish is accelerated due to the inclined state of the support frame 5, so that the overall discharge speed of the varnish is increased, and the operation efficiency is improved.

The cross sections of the supporting rod 6 and the supporting frame 5 are circular, and the supporting rod 6 is cylindrical, so that the supporting rod can have a smaller contact area with a coil when supporting the coil, the paint dipping effect is better, and meanwhile, the supporting rod can have enough strength. And the cross section of the support frame 5 is circular, so when the support frame 5 is rotated upwards, the rotation can be simpler, meanwhile, the abrasion between the support frame 5 and the support ring 4 can be reduced, and the service life of the equipment is prolonged.

After the carriage 5 was put by the slope, bracing piece 6 at this moment all is the slope, so can be more convenient the varnish flow down along bracing piece 6, it has a plurality of dropoff hole 7 to open simultaneously on lock ring 4, not only is convenient for the varnish on carriage 5 to flow down, and the varnish of the body 1 inner wall of also being convenient for simultaneously flows down.

When 5 angles of fixed support frame, take off the second coupler body from third connecting seat 10 at first, later upwards rotate the support frame 5 to suitable angle after, pass the second coupler body on second connecting seat 9, after releasing support frame 5, support frame 5 just can guarantee the stability of angle, simple and convenient. After putting down carriage 5, the second coupler body can pass third connecting seat 10 after, guarantees the position of first coupler body, second coupler body and connecting cable, need not to place separately, is convenient for take next time. The first hook body can also be fixedly connected with the first connecting seat 8 or inseparably movably connected with the first connecting seat 8, so that the first hook body can be prevented from being separated from the first connecting seat 8 in actual use.

The varnish flows down from the inner wall of the supporting part 1a, then can flow into the outer flow part 1b, and finally is discharged to the outside through the discharge pipe 2; at the same time, the outer flow portion 1b is trumpet-shaped, so that its inner wall can better guide the varnish and at the same time can better guide the varnish to the discharge pipe 2. Since the control valve 3 is located outside the support 1a, the operation is facilitated, i.e. the control valve 3 is operated and the connection to an external container is facilitated.

After the paint dipping is finished and the paint dipping tank is cleaned, the sealing cover 11 on the top of the body 1 is used for sealing the body 1, and the sealing cover 11 can be used again next time; and the operation handle 12 can facilitate the operation of moving the sealing cover 11.

In the present invention, unless otherwise explicitly specified or limited, for example, it may be fixedly connected, detachably connected, or integrated; can be mechanically or electrically connected; they may be directly connected or indirectly connected through an intermediate medium, and may be connected through the inside of two elements or in an interaction relationship between two elements, unless otherwise specifically defined, and the specific meaning of the above terms in the present invention will be understood by those skilled in the art according to specific situations.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
