Description

Technical Field

[0001] This utility model relates to the field of deep-sea self-pressure sealing chamber technology, specifically providing a bladder and a deep-sea self-pressure sealing chamber. Background Technology

[0002] The existing deep-sea self-pressure sealed chamber is equipped with pressure-bearing electronic components and is filled with insulating fluid. The outside of the chamber is in direct contact with seawater. The outer wall of the chamber has a pressure regulating port, on which a planar elastic bladder is sealed. The deformation of the elastic bladder is used to adjust the internal and external pressure balance. At the same time, the pressure difference between the inside and outside of the rubber bladder sealing surface is small, which improves the reliability of the seal.

[0003] However, this type of planar bladder has limited deformation capacity and is prone to tearing under strong water pressure, which can lead to water ingress and short circuit risk in the deep-sea self-pressure sealed chamber. Utility Model Content

[0004] This invention provides a bladder and a deep-sea self-pressure sealing chamber, which solves the problem of limited deformation of planar bladders in the prior art.

[0005] In a first aspect, the present invention provides a sac, comprising a planar elastic member, characterized in that a raised portion is formed in the middle of the planar elastic member, and the circumferential edge of the planar elastic member is a planar portion, wherein the edge of the planar portion to the junction of the raised portion and the planar portion are of equal width;

[0006] The angle between the tangent of the outer wall of the raised portion and the surface of the flat portion is less than 90°;

[0007] The bladder is used to fix the pressure regulating port of the deep-sea self-pressure sealing chamber.

[0008] According to the scabbard provided by this utility model, the raised portion is spherical.

[0009] According to the scabbard provided by this utility model, the raised portion is a frustum shape.

[0010] According to the bladder provided by this utility model, the flat part has a plurality of fixing and mounting holes.

[0011] The material of the bladder provided by this utility model is rubber.

[0012] Secondly, this utility model also provides a deep-sea self-pressure sealing chamber, including the bladder mentioned in the first aspect above, and also including a chamber body, the chamber body having a first cavity and a pressure regulating port, the pressure regulating port being connected to the first cavity;

[0013] The bladder is sealed and installed at the pressure regulating port.

[0014] According to the deep-sea self-pressure sealing chamber provided by this utility model, the flat part of the bladder is installed on the inner wall surface of the pressure regulating port, and the raised part is raised towards the first cavity.

[0015] The raised portion is spherical.

[0016] According to the deep-sea self-pressure sealing chamber provided by this utility model, the flat part of the bladder is installed on the outer wall of the pressure regulating port, and the raised part protrudes in a direction away from the first cavity.

[0017] The raised portion is a frustum shape.

[0018] This utility model provides a type of elastic bladder that improves upon the traditional planar elastic bladder by creating an elastic bladder with a central bulge. When the elastic bladder is installed at the pressure regulating port of a deep-sea self-pressure-bearing sealed chamber, with the bulge facing outwards, the bulge increases the overall pressure-bearing range of the elastic bladder. This allows the bulge structure to have a larger elastic space compared to the planar structure under the high pressure environment of the deep sea, thus enabling it to withstand greater seawater pressure and preventing it from tearing. This solves the problem of limited deformation in existing planar bladders.

[0019] By setting the width of the flat part to the junction of the raised part and the flat part to be the same, the raised part can be placed in the middle of the whole skin bag, so that the whole skin bag is evenly compressed.

[0020] By setting the angle between the tangent of the outer wall of the raised portion and the surface of the flat portion to less than 90°, the raised portion as a whole can be made to indent inward when under pressure, that is, all of them have a tendency to indent towards the center point, so as to balance the pressure of seawater in different directions.

[0021] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0041] The following is combined Figures 1 to 11 The embodiments shown illustrate the technical solution of this utility model:

[0042] This utility model embodiment provides a skin pouch, such as Figures 1 to 3 As shown, it includes: a planar elastic member 1, a raised portion 101 formed in the middle of the planar elastic member 1, and a planar portion 102 along the circumferential edge of the planar elastic member 1, the edge of the planar portion 102 to the junction of the raised portion 101 and the planar portion 102 are of equal width.

[0043] The angle between the tangent of the outer wall of the raised portion 101 and the surface of the flat portion 102 is less than 90°;

[0044] The bladder is used to secure the pressure regulating port of the deep-sea self-pressure sealed chamber.

[0045] In some embodiments, the planar elastic element 1 can be made of synthetic rubber, polymer composite material, reinforced material, or special functional material, which can have good deformation ability, so that the bladder has a stronger elastic space and can withstand stronger underwater pressure.

[0046] In this embodiment, the bladder is configured as a planar elastic element 1, and a raised portion 101 is formed in the middle of the planar elastic element 1. The planar elastic element 1 has a planar portion 102 along its circumferential edge. The planar elastic element 1 is fixed to the pressure regulating port of the pressure-bearing sealed chamber. The raised portion 101 faces out of the chamber body, and the angle α between the tangent of the outer wall surface of the raised portion 101 and the planar portion 102 is less than 90°, so that the raised portion 101 is concave inward when under pressure. This allows the bladder to adjust the pressure on the entire pressure-bearing chamber uniformly through deformation in the deep-sea environment, ensuring the normal use of the pressure-bearing sealed chamber.

[0047] This utility model provides a type of elastic bladder that improves upon the traditional planar elastic bladder by having a central raised portion 101. When the elastic bladder is installed at the pressure regulating port of a deep-sea self-pressure-bearing sealed chamber, and the raised portion 101 faces outward from the chamber, the raised portion 101 can increase the overall pressure-bearing range of the elastic bladder. This allows the raised structure to have a larger elastic space compared to the planar structure under the high pressure environment of the deep sea, thus enabling it to withstand greater seawater pressure and making it less prone to tearing. This solves the problem of limited deformation of planar bladders in the prior art.

[0048] By setting the edge of the flat portion 102 to the junction of the raised portion 101 and the flat portion 102 to be of equal width, the raised portion 101 can be positioned in the exact center of the entire skin bag, so that the entire skin bag is subjected to uniform pressure.

[0049] By setting the angle between the tangent of the outer wall of the raised portion 101 and the surface of the flat portion 102 to less than 90°, the raised portion 101 as a whole can be made to indent inward when under pressure, that is, all of them have a tendency to indent towards the center point, so as to balance the pressure of seawater in different directions.

[0050] The skin bag provided according to the embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the raised portion 101 is spherical.

[0051] In this embodiment, the raised portion 101 is configured as a spherical structure, which provides more space for deformation, thereby increasing the pressure-bearing range of the bladder and enabling it to withstand greater seawater pressure. Furthermore, the tendency to indent towards the center point is basically consistent, allowing it to better balance the pressure in different directions in the seawater.

[0052] The skin bag provided according to the embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the raised portion 101 is a quadrangular frustum shape.

[0053] In this embodiment, the raised portion 101 is configured as a frustum-shaped structure. The raised portion 101 is oriented toward the pressure regulating port of the deep-sea self-pressure sealing chamber. During the pressure-bearing process, the raised portion 101 will be recessed toward the center, thereby balancing the pressure inside and outside the chamber and ensuring the normal operation of the pressure-bearing sealing chamber.

[0054] The skin bag provided according to the embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the flat part 102 has multiple fixing holes 1021.

[0055] In this embodiment, the planar elastic element 1 is installed onto the pressure regulating port of the deep-sea self-pressure sealing chamber through the multiple fixing holes 1021 opened on the planar part 102. This increases the deformation space of the bladder through the raised part 101, thereby increasing the range of pressure it can withstand and ensuring that the bladder will not be easily torn.

[0056] The skin bag provided according to the embodiments of this utility model, such as Figure 1 As shown, the material of the bladder is rubber.

[0057] In this embodiment, the preferred material for the bladder is a rubber structure, which gives the bladder greater elasticity and better pressure resistance when subjected to external pressure. At the same time, it can automatically return to its original shape when the external pressure is removed, thus having a natural recovery ability. This allows the bladder to be reused and reduces manufacturing costs.

[0058] According to an embodiment of this utility model, a deep-sea self-pressure-bearing sealed chamber is provided, such as... Figure 6 and Figure 7 As shown, the device includes the aforementioned bladder and a cabin 2. The cabin 2 has a first cavity 201 and a pressure regulating port 202, which is connected to the first cavity 201.

[0059] The bladder seal is installed at the pressure regulating port 202.

[0060] In this embodiment, the first cavity 201 inside the cabin 2 is used to install various electronic components, and the cabin 2 is provided with a pressure regulating port 202. A bladder is sealed on the pressure regulating port 202. The pressure inside and outside the first cavity 201 is adjusted by the bladder to ensure the safe use of the deep-sea self-pressure sealed cabin.

[0061] According to the deep-sea self-pressure sealing chamber provided by this utility model, such as Figure 10 and Figure 11 As shown, the flat portion 102 of the bladder is mounted on the inner wall of the pressure regulating port 202, and the raised portion 101 protrudes towards the first cavity 201.

[0062] The raised part 101 is spherical.

[0063] In this embodiment, by installing the flat part 102 of the bladder onto the inner wall of the pressure regulating port 202, the raised part 101 is spherical and faces into the first cavity 201. In the deep sea environment, when subjected to seawater pressure, the raised part 101 is compressed in the direction away from the first cavity 201, balancing the pressure inside and outside the deep sea self-pressure sealing chamber, so that the sealing chamber can be used normally.

[0064] According to the deep-sea self-pressure sealing chamber provided by this utility model, such as Figure 8 and Figure 9 As shown, the flat portion 102 of the bladder is mounted on the outer wall of the pressure regulating port 202, and the raised portion 101 protrudes in a direction away from the first cavity 201.

[0065] The raised part 101 is a quadrangular frustum.

[0066] In this embodiment, the flat portion 102 is installed on the inner wall of the deep-sea self-pressure-bearing sealed chamber. Because the raised portion 101 bulges in a direction away from the first cavity 201, in the deep-sea environment, the raised portion 101 is compressed in the direction of the first cavity 201. Moreover, the raised portion 101 is a truncated quadrangular shape, thereby increasing the deformation capacity of the bladder and increasing the pressure-bearing capacity of the pressure-bearing sealed chamber, enabling it to withstand greater pressure and ensuring the normal use of the sealed chamber.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
