DETAILED DESCRIPTION [0018] The present disclosure will be further described below according to embodiments with reference to drawings.

[0019] A ventilation device arranged on a door lintel of the body of a bulk container is taken as an example to explain the present disclosure, which is only illustrative and does not intend to limit the present disclosure. It should be understood by those skilled in the art that the ventilation device may be arranged at any locations, such as an end lintel, an end sill, a top-side beam, a door plate, a door beam, a wall plate, or a top portion, of the body of the bulk container suitable for arranging it.

[0020] Fig. 2 is a schematic view of a bulk container with a ventilation device on its door lintel according to the present disclosure; and Fig. 3 is a cross-sectional view taken along line A-A of the ventilation device of the bulk container illustrated in Fig. 2. As shown in Fig. 2, a plurality of ventilation devices are arranged on the door lintel of the body of the container. [0021] As shown in Fig. 3, a hollow cylinder structure extending in a horizontal direction is surrounded by a door lintel 41 and a door lintel plate 42 of the container. The door lintel 41 is a U-typed structure formed by bending a steel plate, wherein the U-typed structure comprises a front standing plate 411, a rear standing plate 412 and a bottom plate 413 connecting the two standing plates. The door lintel plate 42 is also formed by bending a steel plate and comprises an upper top plate 421, an inclined plate 422 and a lower top plate 423, wherein the upper top plate 421 and the lower top plate 423 extend in the horizontal direction; the inclined plate 422 is connected between the upper top plate 421 and the lower top plate 423; the upper top plate 421 is welded to the front standing plate 411 and the rear standing plate 412; the upper top plate 421 is flush with the front standing plate 411; and the upper top plate 421 is connected with the inclined plate 422 outside the door lintel, i.e. the upper top plate 421 is wider than the bottom plate 413.

[0022] A ventilation pipe 1 is a steel pipe, the outer end of which is welded to the front standing plate 411 of the door lintel 41 to form an air inlet, and the inner end of which is welded to the rear standing plate 412 of the door lintel 41 to form an air outlet. The ventilation pipe 1 is arranged obliquely so that the air outlet is higher than the air inlet to prevent rainwater from flowing into the container.

[0023] A soft cover plate 2 is a thin plate, connected with the rear standing plate 412 of the door lintel of the container by a hinge and mounted at the air outlet of the ventilation pipe 1. The area of the soft cover plate 2 is larger than that of the air outlet of the ventilation pipe 2 so as to cover the air outlet of the ventilation pipe 1, so that the soft cover plate 2 is covered on the air outlet of the ventilation pipe 1 for sealing the bulk container during transportation to prevent moisture from leaking into the body; the air pressure inside the container decreases when unloading, so that the soft cover plate 2 is opened due to the atmosphere pressure.

[0024] A detachable protection housing 3 comprises a first L-typed plate 31, a Z-typed plate 32 and a second L-typed plate 33. The first L-typed plate 31 is welded to the inclined plate 422 of the door lintel plate 42, while the second L-typed plate 33 is welded to the rear standing plate 412 of the door lintel 41; an upper portion and a lower portion of the Z-typed plate 32 are respectively connected with the first L-typed plate 31 and the second L-typed plate 33 by bolt and nut. A hollow cylinder structure extending in the direction of the door lintel is surrounded by a part of the upper top plate 421 and the inclined plate 422 of the door lintel plate 42, the first L-typed plate 31, the Z-typed plate 32 and the second L-typed plate 33 of the detachable protection housing 3, and a part of the rear standing plate 412 of the door lintel plate 42. A plurality of ventilation devices arranged on the door lintel is surrounded by the hollow cylinder structure. The length of the hollow cylinder structure is smaller than the width inside the bulk container, so that a certain distance is formed at each of both ends of the hollow cylinder structure, i.e. the inner space of the hollow cylinder structure is communicated with the inner space of the container, in order to keep ventilating. The detachable protection housing 3 can prevent cargoes from directly pressing against the soft cover plate 2 of the ventilation pipe 1, which affects the effect of ventilating.

[0025] Due to the above ventilation device, the bulk container having the above ventilation device in the present disclosure enables the equilibrium between the air pressures inside and outside the container when there is a pressure difference between the inside and the outside of the bulk container, to avoid the deformation or damage of the container.
