Background

With the development of ocean development industry, underwater cabins appear. The water tightness is the prerequisite and key for realizing the functions of the underwater cabin body. At present, the sealing mode of the cabin body under water is mostly mirror image sealing and end face sealing, and for the rigid plastic shell applied to the deepwater environment, the problem of water leakage caused by long-term deformation of plastic cannot be avoided, so that most of the cabin body under water at present uses metal as shell material, and the weight and the cost are higher.

The typical end face sealing structure comprises a sealing body, wherein the sealing body is provided with a sealing cavity with an upward opening, and a sealing ring and a mounting hole are arranged on the opening edge of the sealing cavity. After the device to be sealed is arranged in the sealing cavity, the end cover matched with the sealing cavity is required to be covered on the end face of the sealing cavity and is fixed through the mounting hole, and therefore packaging is achieved.

In the above-described typical end face seal structure, it can be seen that when rigid plastic is used as the housing of the underwater hull, one of the main causes of deformation of the plastic housing is due to outward extrusion of the seal ring against the plastic housing. The reason is that the sealing ring is generally made of flexible materials, has certain elasticity, and can generate outward pressure, so that the plastic shell is deformed under the outward pressure, and the integral sealing performance of the underwater cabin is affected.

First embodiment

The embodiment provides an underwater sealed cabin, and the specific structure is shown in fig. 1 and fig. 2. Fig. 1 is an overall schematic view of an underwater sealed cabin according to a first embodiment of the present application, and fig. 2 is a schematic view of a sealing position i of the underwater sealed cabin according to the first embodiment of the present application.

As shown in fig. 1, fig. 1 shows an overall schematic view of an underwater hull according to a first embodiment of the present application. It can be seen that the underwater cabin in the first embodiment is mainly composed of a cover 101 and a cabin 103, and a flexible sealing member 102 is disposed between the cover 101 and the cabin 103 for sealing the whole inside of the underwater cabin.

It can be seen that the deck lid 101 and the hull 103 are mated and that the deck lid 101 and the hull 103 are joined to form a closed structure. After the flexible sealing member 102 is installed, the space between the cabin cover 101 and the cabin body 103 may be filled with glue to seal by using an adhesive, which is not used in this embodiment, but the present invention is not limited thereto.

In the present embodiment, the hatch 101 is made of a hard material, typically a rigid material with high rigidity, typically metal. Because the rigid material with high rigidity is more difficult to deform under the action of underwater pressure, the structural stability of the hatch cover 101 ensures that the pressure generated by the deformation of the hatch cover 101 on the cabin body 103 is not too high. Therefore, if the deck lid 101 is made of a rigid material with high rigidity, the material requirement of the deck 103 is lower than that of the deck lid 101. However, the material of the hatch 101 is not limited to metal, and is not limited to a rigid material having high rigidity, and a suitable hard material may be selected. In the present embodiment, the hatch 101 is made of metal, but the present invention is not limited to the material of the hatch 101.

The hatch 101 may be integrally formed or may be separately formed and then assembled during assembly. In the present embodiment, the hatch 101 is integrally formed, but the present invention is not limited thereto.

In this embodiment, the cabin 103 is made of a hard material, generally a hard polymer material, and generally, hard PVC or organic glass may be selected. The cabin 103 is made of a hard polymer material mainly for cost consideration, but the material of the cabin 103 is not limited to hard PVC or organic glass, nor to a hard polymer material, as long as the interior of the cabin can be sealed. In this embodiment, the cabin 103 is made of hard PVC material, but the present invention is not limited to the material of the cabin 103.

The hatches 103 may be integrally formed or may be separately formed and then assembled during assembly. In the present embodiment, the hatch 103 is integrally formed, but the present invention is not limited thereto.

The flexible sealing element 102 is generally used as a sealing ring, but the flexible sealing element 102 is not limited to a sealing ring, and a flexible sealing element capable of generating a sealing effect may be used, for example, the flexible sealing element 102 may be a solid glue formed by curing after glue filling. In the present embodiment, the flexible sealing member 102 is a rubber sealing ring, but the present invention is not limited to the components of the flexible sealing member 102.

In the present embodiment, the flexible sealing member 102 is a rubber sealing ring, which is generally used to seal the sealing area by the external pressure generated by the elastic property of the flexible material itself to the close cabin cover 101 and the cabin body 103. However, the sealing ring may also be in the form of a pneumatic tire, etc., and the sealing of the sealing area is completed by generating external pressure on the abutting hatch 101 and cabin 103 by the gas in the sealing ring. The present invention is not limited thereto.

A schematic structural view of the sealing position I of the underwater cabin of the present embodiment is shown in fig. 2.

As shown in fig. 2, it can be seen that the side wall of the hatch 101 has a groove at the sealing position I. In addition, the side walls of the cabin 103 play a role in the sealing position I in three main parts, one being the protrusion 103A, two being the first platform 103B and three being the second platform 103C. The hatch 101 plays a role in the sealing position I mainly in two parts, one being the groove side wall 101A and the other being the retaining wall 101B. In addition, the deck lid 101 mainly includes a first upper deck 101C1 and a second upper deck 101C 2.

The flexible seal 102 is disposed in the space formed by the first upper land 101C1, the right side of the groove sidewall 101A, the second land 103C, and the left side of the boss 103A. The left side of the flexible sealing element 102 is tightly attached to the right side of the groove side wall 101A, and the right side of the flexible sealing element 102 is tightly attached to the left side of the bulge 103A; in addition, the flexible sealing member 102 may be in contact with the first upper platform 101C1 or the second platform 103C, or may be in non-contact. In the present embodiment, the flexible sealing member 102 is in contact with the first upper platform 101C1 and not in contact with the second platform 103C, but the present invention is not limited thereto.

In the present embodiment, the first upper platform 101C1 and the second upper platform 101C2 are non-coplanar, but the first upper platform 101C1 and the second upper platform 101C2 may also be coplanar, and there is only one upper platform, which is not limited by the present invention.

In addition, as can be seen from fig. 2, the right side of the convex portion 103A is closely attached to the left side of the retaining wall 101B due to the outward pressure generated by the elastic action of the flexible seal member 102. In this embodiment, the upper side of the boss 103A abuts against the lower platform 101C of the hatch 101, and the lower side of the retaining wall 101B abuts against the first platform 103B. However, the upper side of the protruding portion 103A may not contact the second upper platform 101C2 of the hatch 101, and the lower side of the retaining wall 101B may not contact the first platform 103B, which is not limited by the present invention.

As can be seen from the above description, the right side of the protruding portion 103A is tightly attached to the left side of the retaining wall 101B due to the outward pressure of the flexible sealing member 102, and since the hatch 101 is made of a high-rigidity metal material in this embodiment, the retaining wall 101B is not easily deformed, and thus the protruding portion 103A tightly attached to the retaining wall 101B is also not easily deformed. This effectively prevents the cabin 103 made of rigid PVC in this embodiment from deforming under the outward pressure of the flexible sealing member 102, thereby effectively controlling the compression amount of the flexible sealing member 102, not only meeting the sealing and waterproofing requirements, but also reducing the deformation amount of the cabin 103, thereby improving the service life of the cabin 103.

As mentioned above, it can be seen that in this embodiment, at the sealing position I, the side wall of the deck lid 101 has a recess, while the side wall of the deck 103 has a protrusion 103A. However, the side wall of the cover 101 may have a convex portion, and the side wall of the body 103 may have a concave portion, as long as the sealing effect in the present embodiment can be achieved, which is not limited in the present embodiment.

Second embodiment

The embodiment provides another underwater sealed cabin on the basis of the first embodiment, and the specific structure is shown in fig. 3 and 4. Fig. 3 is an overall schematic view of the underwater sealed cabin according to the second embodiment of the present application, and fig. 4 is a schematic structural view of a sealing position ii of the underwater sealed cabin according to the second embodiment of the present application.

Fig. 3 shows a general schematic view of the underwater sealed cabin of the second embodiment of the present application, and as shown in fig. 3, it can be seen that the second embodiment adds an additional hatch 201 above the hatch of the first embodiment, compared to the first embodiment. Since the first embodiment is intended to seal and protect primarily the interior space formed by the hull and the deck lid, while the second embodiment is intended to seal and protect primarily the lower interior space formed by the hull and the deck lid and the upper interior space formed by the deck lid and the additional deck lid.

Fig. 4 is a schematic structural diagram illustrating a sealing position ii of the underwater sealed cabin according to the second embodiment of the present application, as shown in fig. 4, since the sealing position I of the cabin body and the cabin cover has been described and explained in the first embodiment, the second embodiment is described and explained only for the sealing position ii.

The sealing position ii in the second embodiment is mainly composed of an additional hatch 201 and a hatch 203, and a flexible sealing member 202 is arranged between the additional hatch 201 and the hatch 203 and is used for sealing the integral space inside the hatch of the underwater body and the additional hatch.

It can be seen that there is a recess in the surface of the hatch 203, and the recesses of the additional hatch 201 and the hatch 203 are matched, and the recesses of the additional hatch 201 and the hatch 203 are combined to form a closed structure. After the flexible sealing member 202 is installed, the space between the hatch 203 and the additional hatch 201 may be filled with glue to be sealed by using an adhesive, which is not used in this embodiment, but the present invention is not limited thereto.

In this embodiment, the material requirements of the additional hatch 201 and the hatch 203 are the same as those of the cabin 103 and the hatch 101 in the first embodiment, which are not described herein again.

In this embodiment, the requirements of the flexible seal 202 are the same as those of the flexible seal 102 of the first embodiment, and will not be described herein.

As shown in fig. 3 and 4, it can be seen that the side wall of the hatch 203 has a recess in the sealing position ii. The additional hatch 201 plays a role in the sealing position ii in three main parts, one being the bulge 201A, two being the first upper platform 201B and three being the second upper platform 201C. The two parts are mainly used, one is a groove side wall 203A, and the other is a retaining wall 203B. In addition, the hatch 203 also includes a lower platform 203C.

The flexible seal 202 is disposed in the space formed by the first upper land 201B, the left side of the groove sidewall 203A, the lower land 203C, and the right side of the boss 201A. Wherein, the left side of the flexible sealing element 202 is clung to the right side of the bulge 201A, and the right side of the flexible sealing element 202 is clung to the left side of the groove side wall 203A; in addition, the flexible sealing member 202 may be in contact with the first upper platform 201B or the lower platform 203C, or may not be in contact with the first upper platform 201B or the lower platform 203C. In the present embodiment, the flexible sealing member 202 is in contact with the first upper platform 201B and not in contact with the lower platform 203C, but the present invention is not limited thereto.

In this embodiment, the first upper platform 201B and the second upper platform 201C are non-coplanar, but the first upper platform 201B and the second upper platform 201C may also be coplanar, and there is only one upper platform, which is not limited by the present invention.

Further, as can be seen from fig. 4, the left side of the boss 201A abuts against the right side of the retaining wall 203B due to the inward pressure generated by the elastic action of the flexible seal 202. In this embodiment, the underside of the boss 201A abuts against the lower platform 203C of the hatch 203, and the upper side of the groove sidewall 203A abuts against the second upper platform 201C. However, the lower side of the protruding portion 201A may not contact the lower platform 203C of the hatch 203, and the upper side of the groove sidewall 203A may not contact the second upper platform 201C, which is not limited by the present invention.

As can be seen from the above description, the left side of the protruding portion 201A is tightly attached to the right side of the retaining wall 203B due to the inward pressure of the flexible sealing member 202, and the retaining wall 203B is not easily deformed since the hatch 203 is made of a high-rigidity metal material in the present embodiment, so the protruding portion 201A tightly attached to the retaining wall 203B is also not easily deformed. This effectively prevents the additional hatch 201 made of rigid PVC in this embodiment from deforming under the inward pressure of the flexible seal 202, thereby effectively controlling the amount of compression of the flexible seal 202, not only meeting the waterproof sealing requirements, but also reducing the amount of deformation of the additional hatch 201, thereby increasing the service life of the additional hatch 201.

As described above, it can be seen that in the present embodiment, at the sealing position ii, the hatch 203 has a groove, while the additional hatch 201 has a projection 201A. However, the hatch 203 may have a convex portion, and the additional hatch 201 may have a concave portion, as long as the sealing effect in the present embodiment can be achieved, which is not limited in the present embodiment.
