The utility model provides a box-type large transformer shown in figures 1-3, which comprises a box body 1, wherein both sides of the back surface of the box body 1 are respectively provided with a ventilating through groove 2, the inner wall of the ventilating through groove 2 is provided with a filter screen, both sides of the ventilating through groove 2 are respectively fixedly connected with a guide rail 3, the top and the bottom of the guide rail 3 are respectively sleeved with an upper window plate 31 and a lower window plate 32, both sides of the upper window plate 31 are respectively fixedly connected with a stay wire 4, the other end of the stay wire 4 is fixedly connected with the lower window plate 32, the top of the stay wire 4 is movably connected with a guide wheel 5, the guide wheel 5 is movably connected with the back surface of the inner wall of the box body 1 through a pin shaft, the middle part of the lower window plate 32 is fixedly connected with a pull rod 6, the top of the pull rod 6 is fixedly connected with a floating ball 61, the floating ball 61 is arranged on the inner wall of a groove 81, the bottoms of both sides of the lower window plate 32 are respectively fixedly connected with a balancing weight 7, and the top of the box body 1 is fixedly connected with a water collecting hopper 8, recess 81 has been seted up to the both sides of water collecting bucket 8, the fixed interlude in back of water collecting bucket 8 has main downcomer 9, box body 1 is run through to main downcomer 9' S bottom, the top setting of main downcomer 9 is at the top of water collecting bucket 8, the equal fixedly connected with return bend 10 in both sides of main downcomer 9 bottom, the other end of return bend 10 runs through box body 1 and extends to the outside of box body 1, return bend 10 is the S type setting at the inner wall of absorber plate 11, the outside cover of return bend 10 is equipped with absorber plate 11, absorber plate 11 is the copper, the back fixed connection of absorber plate 11 and box body 1 inner wall.

When rainy day, thereby water catch bucket 8 collects the rainwater and pulls floater 61 and shifts up for last luffer board 31 and luffer board 32 are close to each other down, seal ventilative logical groove 2, prevent that the rainwater from getting into the inner wall of box body 1.

After sealing ventilative logical groove 2, the rainwater of water catch bowl 8 inner wall flows at return bend 10 inner walls, absorbs the heat of box body 1 inner wall and arranges to the outside of box body 1 to when realizing sealing ventilative logical groove 2 in the rainy day, can utilize the rainwater to dispel the heat to the inner wall of box body 1.

When the weather is clear, the water of 8 inner walls of water collecting bucket is evaporated by solar irradiation, and luffer boards 32 move down to reset under the pulling of balancing weight 7, and luffer boards 31 reset on pulling wire 4 pulling simultaneously through coming to make this box large-scale transformer can no longer seal ventilative logical groove 2 when weather is clear, and then improved the device's practicality.

This practical theory of operation: this transformer is when using, and the rainy day rainwater can fall into in water collecting bucket 8 and pours into the inner wall of recess 81 gradually, and the water of recess 81 inner wall is full of and promotes floater 61 gradually, and floater 61 shifts up and then shifts up through luffer board 32 under the pull rod 6 pulling, and luffer board 32 shifts up and makes 4 of acting as go-between no longer upwards pull luffer board 31 down for luffer board 31 moves down under the action of gravity.

Thereby realize when rainy day, thereby water catch bucket 8 collects the rainwater and pulls floater 61 and shifts up for last luffer board 31 and luffer board 32 are close to each other down, seal ventilative logical groove 2, prevent that the rainwater from getting into the inner wall of box body 1.

Close to each other at last luffer board 31 and luffer board 32, seal ventilative logical groove 2 after, the rainwater of water collecting bucket 8 inner wall accumulates more gradually, main downcomer 9 is crossed gradually to the water line of water collecting bucket 8 inner wall, the rainwater gets into main downcomer 9 and arranges to the outside of box body 1 from return bend 10, the rainwater is when return bend 10 inner wall flows, the heat of box body 1 inner wall can be absorbed to absorber plate 11, give return bend 10 for the medium transfer with self, again by return bend 10 with the heat transfer for the rainwater of return bend 10 inner wall and arrange to the outside of box body 1, thereby realize when sealing ventilative logical groove 2 in the rainy day, can utilize the rainwater to dispel the heat to the inner wall of box body 1.

When the weather is clear, the water of 8 inner walls of water collecting bucket is evaporated by solar irradiation, the floating ball 61 no longer receives buoyancy, the balancing weight 7 can pull the lower window plate 32 to move down and reset, and the pull wire 4 pulls the upper window plate 31 to reset simultaneously, so that the box-type large transformer can not seal the ventilating through groove 2 when the weather is clear, and further the practicability of the device is improved.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the utility model.
