The fastening piece and the sealing strip are used for guaranteeing the sealing connection between the box cover and the box body, and the problem that oil in the box body is leaked due to deep water pressure can be prevented.
Preferably, a lithium battery or a hydraulic system or a circuit board is arranged in the box body. Lithium batteries, hydraulic systems, circuit boards and the like are all devices required to be used in submarine scientific investigation, and can not be exposed in water and can be placed in oil; instead of being placed separately, they may be placed together in a single housing.
Preferably, the chute on the box cover is a conical groove, the top of the chute is a plane and is communicated with the oil filling hole and the exhaust hole, and the side surface of the chute is an inclined surface. The side of the case lid and the sealed contact of box of this scheme, its chute bottom is unanimous with box opening face shape size, and the chute top then sets up a less plane, and the side of being connected from the chute bottom to the top facet is the inclined plane, can make when refueling gaseous can rise facet department along the inclined plane in the box like this, guarantees that exhaust is thorough.
Preferably, the water outlet, the oil filling hole and the exhaust hole are all provided with detachable plugs. The plug of this scheme for during the outlet, can replace with the stop valve, when the box is great, need adopt to add oil pipe and refuel, but the oil filler hole external joint this moment, convenient and add oil pipe connection.
Compared with the prior art, the beneficial effects of the utility model are that: the air exhaust and drainage are convenient, and the pressure inside and outside the box body can be kept consistent underwater.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.
Referring to fig. 1-4, the present invention provides a technical solution:
an internal and external pressure balance box body used for underwater exhaust and drainage, which comprises a box body 1 and a box cover 2, wherein the inner bottom surface of the box body 1 is an inclined plane relative to the outer bottom surface of the box body 1, a water outlet 3 is arranged at the bottom of the side surface of the box body 1, which is positioned at the lower part of the inner bottom surface of the box body 1 when the outer bottom surface of the box body 1 is horizontally placed, an elastic storage bag 4 is arranged in the box body 1, a liquid inlet 5 communicated with the elastic storage bag 4 is arranged on the side surface of the box body 1, the box cover 2 is hermetically connected with the box body 1, a chute 6 is arranged on the side surface, which is tightly attached to the box body 1, of the box cover 2;
