Abstract
Description
Technical Field
[0001] The present invention belongs to the field of underwater battery compartments, and particularly relates to a deep-sea watertight compartment capable of efficiently and stably installing large batteries. Background Art
[0002] Deep-sea electronic instruments usually need to work underwater for a long time. Relying only on the power supply of the instrument itself cannot meet the requirements of long-term operation. Therefore, it is chosen to encapsulate the battery into a watertight compartment as an external power supply to supply power to the deep-sea instrument, so as to extend the working cycle of the instrument.
[0003] Currently, underwater battery compartments usually design a fixed frame inside to stably install the battery. Although the setting of the fixed frame can stably install the battery, it inevitably occupies the internal space of the battery compartment and increases the external dimension and overall weight. At the same time, while the upper and lower end covers are pressed to restrict the up and down movement of the battery, only relying on the locking friction of the nut to restrict the rotation of the battery around the axis, it is very easy to cause accidental rotation of the battery.
[0004] Therefore, the existing technology is only applicable to small-sized and small-weight batteries. If this technical solution is continued to install large-sized and large-weight large batteries, the threaded fixing rod is easily bent by the large battery during the loading process and causes the problem of eccentricity in the final installation state, there is a greater risk of damage. At the same time, once the watertight compartment is tilted, only relying on the nut cannot bear the weight of the battery, and the nut locking itself will also be loose, and the battery will have the risk of unstable rotation around the axis, which poses a greater safety hazard to deep-sea operations. Therefore, a new device needs to be designed. Summary of the Invention
[0005] The purpose of the present invention is to provide a deep-sea watertight compartment capable of efficiently and stably installing large batteries to solve the problems raised in the above background art.
[0006] To achieve the above purpose, the present invention provides the following technical solutions:
[0007] A deep - sea watertight cabin for efficiently and stably installing large - sized batteries, comprising a lower cover assembly, a battery body, and an upper cover assembly.

Detailed implementation manners

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0029] Please refer to Figures 1-6 , a deep-sea watertight cabin for efficiently and stably installing large batteries, including a lower cover assembly, a battery body 5 and an upper cover assembly, further including a cabin assembly installed between the lower cover assembly and the upper cover assembly for limit installation and circumferential protection, and an installation assembly 4 for pressing and supporting the fixed battery body 5 is arranged in the cabin assembly.
[0030] In this embodiment: the upper cover assembly includes an upper end cover 3, a third sealing ring 3-1 is installed on the side of the upper end cover 3, two upper positioning pins 3-2 are symmetrically installed on the upper end cover 3, an upper load-bearing block 3-3 is arranged inside the upper end cover 3, a plurality of upper concave through holes 3-4 and upper disassembly screw holes 3-5 are evenly distributed on the circumference of the upper end cover 3, the upper concave through holes 3-4 correspond to the internal thread holes 2-4 one by one, three first screw holes 3-9, second screw holes 3-10 and third screw holes 3-11 with different sizes are evenly distributed on the circumference of the top of the upper end cover 3, and first connectors 3-6, second connectors 3-7 and third connectors 3-8 installed corresponding to them; the first connectors 3-6, second connectors 3-7 and third connectors 3-8 respectively adopt watertight and pressure-resistant connectors for supplying power to the deep-sea electronic cabin through an external interconnection cable as an external power source; the upper positioning pins 3-2 are threadedly connected to the upper end cover 3;
[0031] In this embodiment: The cabin assembly includes a cabin shell 2. On the inner wall of the cabin shell 2, an integrated structure 2-2 is symmetrically arranged. The integrated structure 2-2 adopts a structure of a symmetric guide rail base plus three inner rings. Second sealing rings 2-1 are installed on both end faces of the cabin shell 2. On both end faces of the cabin shell 2, two positioning holes 2-3 are symmetrically arranged respectively, and twelve internal threaded holes 2-4 are evenly distributed along the circumference.
[0032] In this embodiment: A central through hole 5-1 is arranged in the middle of the battery body 5. On both sides of the battery body 5, limiting guide rails 5-2 are symmetrically arranged. The central through hole 5-1 is used to pass through the threaded fixing rod 4-2. The limiting guide rails 5-2 of the battery body 5 slide along the integrated structure 2-2 of the symmetric guide rail base plus three inner rings of the cabin shell 2 to install and fix the battery body 5.
[0033] In this embodiment: The installation assembly 4 includes a base cross 4-1. A base flat plate 4-4 is installed on the base cross 4-1. A threaded fixing rod 4-2 is installed at the center of the base cross 4-1. An upper flat plate 4-5 is installed on the upper part of the threaded fixing rod 4-2. Two hexagonal nuts 4-3 are installed at both ends of the threaded fixing rod 4-2 respectively. Threaded fixing rod 4-2 is provided with an external thread at both ends.
[0034] In this embodiment: The lower cover assembly includes a lower end cover 1. A first sealing ring 1-1 is installed on the side of the lower end cover 1. Two lower positioning pins 1-2 are symmetrically installed on the lower end cover 1. A lower load-bearing block 1-3 is arranged inside the lower end cover 1. A number of lower concave head through holes 1-4 and lower disassembly threaded holes 1-5 are evenly distributed on the circumference of the lower end cover 1. The lower concave head through holes 1-4 correspond to the internal threaded holes 2-4 one by one. The lower positioning pin 1-2 is threadedly connected to the lower end cover 1.
[0035] Working principle: During installation, one end of the external thread of the threaded fixing rod 4-2 passes through the central through hole 5-1 of the base flat plate 4-4, and then is threadedly mated and screwed with the center thread of the base cross 4-1. Two hexagonal nuts 4-3 are tightened with a spring washer (the pre-tightening force between the hexagonal nut 4-3 and the base cross 4-1 is 80% of the pre-tightening force between the two hexagonal nuts 4-3). The base cross 4-1 is aligned and installed with the lower load-bearing block 1-3 inside the lower end cover 1 through the spring washer and the screw.
[0036] Install a second sealing ring 2-1 on the end face of the cabin shell 2, and install two first sealing rings 1-1 on the side of the lower end cover 1. (When installing all the sealing rings, a layer of sealing silicone grease needs to be applied externally to improve the sealing performance.) Align the lower positioning pin 1-2 with the positioning hole 2-3, and position and assemble the lower end cover 1 and the cabin shell 2. Use four long screws to pass through the lower concave through hole 1-4 and screw into the internal thread hole 2-4 to drive the lower end cover 1 and the cabin shell 2 to complete the fitting. The first sealing ring 1-1 is on the inner side of the cabin shell 2 and is squeezed by the mutual extrusion of the lower end cover 1 and the cabin shell 2 to achieve sealing. After the lower end cover 1 and the cabin shell 2 are assembled, replace them with twelve groups of flat washers, spring washers and screw combinations and tighten them. The evenly distributed flat washers, spring washers and screw combinations effectively compress the lower end cover 1 to ensure the sealing performance. Thus, the installation of the lower end cover 1 is completed;
[0037] Pass the central through hole 5-1 of the battery body 5 through the threaded fixing rod 4-2 from the end of the upper end cover 3 of the cabin shell 2. The limiting guide rail 5-2 of the battery body 5 slides along the integrated structure 2-2 of the symmetric guide rail base of the cabin shell 2 plus three inner rings, and install the battery body 5 on the base plate 4-4. Sleeve the upper plate 4-5 from the top of the threaded fixing rod 4-2 and press it on the upper surface of the battery body 5, and tighten two hex nuts 4-3 with spring washers. Paste an elastic gasket material on the surface of the upper plate 4-5 to press the battery body 5, which not only plays a shock-absorbing role but also reduces the wear between the upper plate 4-5 and the internal upper load-bearing block 3-3;
[0038] Install the first connector 3-6, the second connector 3-7 and the third connector 3-8 at the first screw hole 3-9, the second screw hole 3-10 and the third screw hole 3-11 of the upper end cover 3 respectively. Install a second sealing ring 2-1 on the end face of the cabin shell 2, and install two third sealing rings 3-1 on the side of the upper end cover 3. Align the upper positioning pin 3-2 with the positioning hole 2-3, and position and assemble the upper end cover 3 and the cabin shell 2. Use four long screws to pass through the upper concave through hole 3-4 and screw into the internal thread hole 2-4 to drive the upper end cover 3 and the cabin shell 2 to complete the fitting. The third sealing ring 3-1 is on the inner side of the cabin shell 2 and is squeezed by the mutual extrusion of the upper end cover 3 and the cabin shell 2 to achieve sealing. After the upper end cover 3 and the cabin shell 2 are assembled, replace them with twelve groups of flat washers, spring washers and screw combinations and tighten them. The evenly distributed flat washers, spring washers and screw combinations effectively compress the upper end cover 3 to ensure the sealing performance. The upper load-bearing block 3-3 presses the battery body 5 through the upper plate 4-5. Thus, the installation of the upper end cover 3 is completed.
[0039] When disassembling, synchronously screw four long screws into the upper disassembly screw hole 3-5 of the upper end cover 3 to the end face of the cabin shell 2, and separate the upper end cover 3 and the cabin shell 2 by continuously applying force through the thread. The disassembly method of the lower end cover 1 and the cabin is the same.
