Description of the embodiments

The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.

As shown in fig. 1 and 2, a waterproof end cover of a transformer comprises a bottom plate 1 and an end cover 2, wherein the top of the bottom plate 1 is connected with the end cover 2 through welding, a heat dissipation groove 4 is formed in the bottom plate 1, a coil pipe 5 for assisting heat dissipation is connected in the heat dissipation groove 4 through gluing, and a heat conducting plate 6 is arranged at the bottom of the coil pipe 5 in the bottom plate 1.

The bottom of the bottom plate 1 is provided with a sliding groove 9, and a pull rod 10 is connected in the sliding groove 9 in an inner sleeve manner.

In this embodiment, as shown in fig. 3, the sliding groove 9 and the pull rod 10 are slidably connected, so that the use position of the connecting mechanism can be adjusted, and further, the contact between the connecting piece and external rainwater is reduced, and the use is not easily affected by corrosion.

The top of the end cover 2 is provided with a groove 3, a water inlet 7 is arranged in the groove 3, and the water inlet 7 is communicated with the coil pipe 5.

In this embodiment, as shown in figure 2, the introduction of external part of the stormwater into the coil 5 is facilitated by the recess 3 and the water inlet 7.
