As shown in fig. 3, the cables 1 need to be passed through the hull 5 of the underwater hull, at which time the threading points need to be sealed to prevent water from entering the underwater hull via the threading points. Therefore, the embodiment provides the threading sealing structure of the underwater cabin body, which comprises a first soft baffle 2A, a sealing colloid 3, a second soft baffle 2B and a shell 5.
The shell 5 is made of hard materials, generally, a cabin body of the underwater pressure cabin is mostly made of hard transparent materials, such as hard PVC and the like, and the shell 5 is generally made of glass brittle materials. However, the present invention is not limited to the above-mentioned hard transparent material, and a hard non-transparent material may be used.
As shown in fig. 1 and 3, the housing 5 includes a bottom surface and a circumferential side wall lacking one surface. The shape of the semi-spherical surface can be a semi-spherical surface with an unclosed circular cross section lacking one surface, or a regular or irregular cube, cuboid or polyhedron lacking two adjacent surfaces, and the shape can be designed at will.
In general, the housing 5 can be considered to include a first side wall 51, a second side wall 52, a third side wall 53, a bottom 54 connected to the bottom of the third side wall, and a U-shaped groove 55 formed by the first side wall 51, the second side wall 52, and the bottom 54. The five parts together with the first soft baffle 2A enclose a space which is just the glue filling area.
As described above, in the present embodiment, the housing 5 has three side walls and one bottom surface, but the housing 5 is not limited to three side walls and one bottom surface, and may have one or even a plurality of side walls or a plurality of bottom surfaces, as long as it is ensured that the existence of the potting region can be achieved finally.
As shown in fig. 1 and 2, the housing 5 is an integral structure in this embodiment, but each part can be separately processed and assembled, so that each part can be separately processed and assembled to facilitate replacement or repair of damaged parts, as long as the sealing performance of the connection of each part of the housing 5 under water can be ensured.
The housing 5 itself is perforated at the third side wall 53, and an annular protrusion 532 surrounding the through hole 531 is formed outside the through hole 531. The smallest circle of the annular projection structure 532 has a diameter equal to or larger than the diameter of the through hole 531.
As shown in fig. 3, a second soft baffle 2B is provided inside the through hole 531 in close contact with the third side wall 53 of the housing 5. The second soft baffle 2B may be firmly connected to the inside of the third side wall 53 by using an adhesive method, or may be fixed by using other methods such as a bolt, and is not limited to the above adhesive method.
In the present embodiment, the height dimensions of the first side wall 51, the second side wall 52, and the third side wall 53 are uniform, so as to ensure that the sealant 3 is filled everywhere in the sealant filling area when in the liquid sealant state, but the height dimensions may also be designed to be non-uniform.
In the present embodiment, the surfaces of the first side wall 51, the second side wall 52, the third side wall 53 and the bottom surface 54 are flat, but may be designed to be uneven such as protruding or recessed, as long as the glue filling is not affected.
As described above, the second soft baffle 2B is closely attached to the inner side of the third side wall 53, and the second soft baffle 2B is also subjected to the punching operation, and the soft hole 2B1 obtained by punching is substantially aligned with the through hole 531. The diameter of the soft body hole 2B1 is slightly smaller than the cross-sectional diameter of the cable 1. The diameter of the through hole 531 is slightly larger than or equal to the diameter of the cross section of the cable 1.
The first soft baffle 2A is embedded in the U-shaped groove 55. The first soft baffle 2A and the U-shaped groove 55 can be connected by bonding or can be arranged in the U-shaped groove 55 only under the action of gravity.
The thickness of the first soft baffle 2A may be slightly larger or smaller than the width of the U-shaped groove 55, it should be noted that if the first soft baffle 2A is too thick, the first soft baffle 2A cannot be placed in the U-shaped groove 55, and if the first soft baffle 2A is too thin, the liquid colloid is likely to leak from the edge of the first soft baffle 2A outside the glue filling area.
The length of the first soft baffle 2A may be slightly greater or smaller than the length of the U-shaped groove 55, it should be noted that if the first soft baffle 2A is too long, the first soft baffle 2A cannot be placed in the U-shaped groove 55, and if the first soft baffle 2A is too short, the liquid colloid is likely to leak from the edge of the first soft baffle 2A outside the glue filling area.
The height of the first soft baffle 2A can be slightly larger or smaller than the height of the U-shaped groove 55, it should be noted that if the first soft baffle 2A is too high, the material of the first soft baffle 2A will be wasted, and if the first soft baffle 2A is too short, the amount of glue in the glue filling area will be too small, and the sealing effect cannot be ensured.
The first soft baffle 2A is also opened to obtain soft holes 2A 1. The diameter of the soft hole 2A1 is similar to the diameter of the soft hole 2B1, and is slightly smaller than the cross-sectional diameter of the cable 1. Ideally, the connection line between the center of the soft hole 2a1 and the center of the soft hole 2B1 needs to be perpendicular to the soft hole 2a1, and the soft hole 2a1, the through hole 531 and the soft hole 2B1 are parallel to each other and are sequentially arranged to form a pipeline shape, thereby forming a threading channel. In practical situations, it is desirable to make the cable 1 close to the ideal situation, and if the difference is too large, the cable 1 may not pass through the soft hole 2a1, the through hole 531 and the soft hole 2B1 at the same time.
The first soft baffle 2A and the second soft baffle 2B are both made of flexible materials. The material may be silicone rubber, thermoplastic polyurethane elastomer rubber TPU, or the like. The materials of the first soft baffle plate 2A and the second soft baffle plate 2B can be consistent or inconsistent; the dimensions may or may not be uniform.
The cable 1 simultaneously passes through the soft hole 2A1, the soft hole 2B1 and the through hole 531, and the cable 1 is respectively in interference fit with the soft hole 2A1 and the soft hole 2B 1. The interference fit has the advantage that liquid glue can be prevented from flowing out of gaps between the cable and the soft hole during glue filling.
The material of the cable 1 is not determined and may be a flexible material such as silicone rubber, thermoplastic polyurethane elastomer rubber TPU, etc.; but also hard materials such as hard PVC, metals, etc. However, when the material is selected to be flexible, the flexible material with higher elastic modulus needs to be selected to prevent the material from generating excessive deformation under stress.
In the present embodiment, there are 3 cables 1, each having 3 soft holes 2a1, 2B1 and a through hole 531. However, the number of the cables 1 and the holes is not limited to 3, and may be any number as long as the number of the cables 1 can match with the number of the holes.
As shown in fig. 3 and 4, after the first soft baffle 2A and the second soft baffle 2B are positioned, and the cable 1 is passed through the soft hole 2A1, the through hole 531 and the soft hole 2B1, the liquid colloid is poured into the box-shaped space.
The liquid colloid can be flexible solidified sealant, and the solidified sealant 3 has certain elasticity, and can be selected from but not limited to underwater special epoxy resin sealant.
As shown in fig. 3, the through hole 531 is not in an interference fit state with the cable 1, in which a small gap exists, and the gap is elongated by the presence of the annular protrusion structure 532. The liquid gel 31 flows into the gap and is blocked by the interference fit between the soft hole 2B1 and the cable 1.
The liquid colloid forms a sealing colloid 3 after solidification. The sealing glue 3 in the glue filling area forms a first sealing protection. Because the sealing colloid 3 is generally made of flexible curing sealant with certain elasticity, the sealing colloid can not be cracked like rigid curing sealant under the action of deep water pressure, but becomes tighter and denser, and the underwater sealing effect is enhanced.
As shown in fig. 3, the gap between the through hole 531 and the cable 1 is filled with the sealant 3, so as to lengthen the path of water leakage, thereby forming a second sealing protection.
The soft hole 2B1 forms a third sealing protection in the interference fit state with the cable 1.
As mentioned above, under the effect of three sealed protections, the utility model provides an underwater cabin body threading seal structure is reliable, possibility greatly reduced that became invalid.
As above, can see, the utility model provides an underwater cabin body threading seal structure volume is very little, only depends on the regional size of encapsulating, under the circumstances of guaranteeing the leakproofness, can compress the encapsulating region as far as possible.
As mentioned above, the utility model provides an underwater cabin body threading seal structure compares in expensive watertight bayonet joint, and the cost is lower, and the prime cost of consumption only lies in two software baffles and sealing colloid.
As the above, the utility model provides an underwater cabin body threading seal structure, the time mainly spends at the solidification process of liquid colloid, but because need not to carry out manual operation this moment, the solidification process of liquid colloid many times can go on simultaneously, and the average time of single encapsulating operation has obtained further shortening.
The above-mentioned explanation is gone on with the cabin body under water as an example, however, the utility model provides a this kind of seal structure is not limited to the cabin body under water, can also be applied to all the other waterproof equipment of needs or as the airtight structure in anhydrous region under water.
Finally, it should be noted that: it should be understood that the above examples are only for clearly illustrating the present invention and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious changes and modifications may be made without departing from the scope of the present invention.
