[0041] like Figure 1 As shown, in the prior art, underwater battery packs generally have sliders 5 installed or welded on both sides of the battery pack shell, which are then fixed in place with guide grooves 6 opened on the inner wall of the pressure tank. This fixing method not only occupies space inside the pressure tank, but also increases the weight of the battery pack, thereby reducing the space utilization rate of the battery pack.

[0042] The following is combined Figures 2 to 11 The embodiments shown illustrate the technical solution of this utility model:

[0043] This utility model provides an underwater pressure-resistant tank battery pack fixing assembly and an underwater pressure-resistant tank, such as... Figure 2 and Figure 4 As shown, it includes: slide rail 1, limit plate 2, battery mounting plate 3 and limit component 4;

[0044] The slide rail 1 has at least two sections for parallel installation on the inner wall of the pressure-resistant chamber body; the limiting plate 2 has at least two sections, respectively disposed at both ends of the slide rail 1; the battery mounting plate 3 has multiple sections, respectively coaxially disposed between the two limiting plates 2 and fixedly installed on the slide rail 1, the outer contour of the battery mounting plate 3 matches the inner wall of the pressure-resistant chamber body; the limiting member 4 has multiple sections, respectively evenly distributed and installed on the opposite side of the limiting plate 2, and is used for installation on the inner wall of the pressure-resistant chamber body.

[0045] In some embodiments, the slide rail 1 may be provided in four sets, two in each set, arranged parallel to the inner wall of the pressure-resistant chamber body; the limiting plate 2 may be provided in four sets, two in each set, arranged at both ends of the slide rail 1, each limiting plate 2 having a cross-sectional area of ​​90° sector, and four limiting plates 2 forming a circular plate; similarly, there may be multiple battery mounting plates 3, arranged between the limiting plates 2, each battery mounting plate 3 being a 90° sector plate, and four battery mounting plates 3 forming a circular plate, that is, the outer contours of multiple limiting plates 2 and multiple battery mounting plates 3 combined together can cover the cross-section of the inner wall of the pressure-resistant chamber body;

[0046] In this embodiment, as Figure 2 As shown, there are two slide rails 1, which are installed parallel to each other on the inner wall of the pressure-resistant chamber. Limiting plates 2 are provided at both ends of the slide rails 1. The outer contour of the limiting plates 2 fits against the inner wall of the pressure-resistant chamber. Multiple battery mounting plates 3 are fixedly installed on the slide rails 1. Limiting components 4 are installed on the opposite side of the limiting plates 2. The limiting components 4 can fix the limiting plates 2 to the pressure-resistant chamber and fix and limit the limiting plates 2. The slide rails 1, limiting plates 2, and limiting components 4 constitute a limiting mechanism for fixing multiple battery mounting plates 3 in the pressure-resistant chamber. Multiple batteries are mounted on the battery mounting plates 3.

[0047] During assembly, slide rail 1 is installed on the inner wall of the pressure chamber body. A single limiting plate 2 is placed on one side of slide rail 1. On the side of the limiting plate 2 near the other end of slide rail 1, a battery mounting plate 3 is placed on slide rail 1. Batteries are installed on battery mounting plate 3 until the battery mounting plate 3 is fully covered with batteries. After installation, another battery mounting plate 3 is placed on slide rail 1 near the side of the battery mounting plate 3 away from the initial limiting plate 2. The above battery installation steps are repeated until the slide rail 1 can no longer accommodate battery mounting plates 3. Then, another limiting plate 2 is placed on slide rail 1, so that the two limiting plates 2 clamp the installed battery mounting plate 3. The limiting plate 2 is connected to the pressure chamber body through the limiting member 4, thus completing the battery installation in the pressure chamber.

[0048] This utility model provides a battery pack fixing assembly for an underwater pressure tank. By improving the guide groove 6 on the inner wall of the traditional pressure tank body into a guide rail, the guide rail 1 can be processed and installed separately, greatly reducing the processing difficulty of the guide groove 6 inside the pressure tank. By setting the outer contour of the battery mounting plate 3 to match the inner wall of the pressure tank body, the maximum utilization of the pressure tank's internal area can be achieved, avoiding the waste of limited internal space. This effectively solves the problem in the prior art that the connection between the underwater environment battery pack and the pressure tank easily occupies the pressure tank space. Through the setting of the limiting plate 2 and the limiting member 4, multiple battery mounting plates 3 can be fixed and limited.

[0049] According to the battery fixing assembly provided in the embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the limiting member 4 includes a limiting block assembly 401, and the limiting block assembly 401 has a first mounting hole 4011 and a second mounting hole 4012.

[0050] The axes of the first mounting hole 4011 and the second mounting hole 4012 are perpendicular to each other and are both used for mounting fastening components.

[0051] In some embodiments, the limiting member 4 may be a combination of bolts and lock nuts, used to fix the limiting plate 2 and the inner wall of the pressure chamber, and at the same time fix the limiting plate 2 to prevent it from falling off the slide rail 1; the fastening components may be pins, screws, etc., to fix the limiting member 4 to the limiting plate 2 and the pressure chamber.

[0052] In this embodiment, the limiting member 4 is preferably a limiting block assembly 401, and the fastening assembly is preferably a screw. The limiting block assembly 401 has a first mounting hole 4011 and a second mounting hole 4012, and the axes of the first mounting hole 4011 and the second mounting hole 4012 are perpendicular to each other. Both are used for the installation of the fastening assembly. The fastening assembly passes through the first mounting hole 4011 and the second mounting hole 4012 respectively, thereby fixing the limiting plate 2 to the inner wall of the pressure chamber, and limiting the positional relationship of the limiting plate 2 to prevent the limiting plate 2 from shaking due to some external factors.

[0053] According to the battery fixing assembly provided in the embodiments of this utility model, such as Figure 6 As shown, it also includes guide rods 7, of which there are multiple guide rods 7, all of which are arranged parallel to the axis of the battery mounting plate 3;

[0054] The guide rod 7 passes through the two limiting plates 2 and the battery mounting plate 3 in sequence.

[0055] In this embodiment, multiple guide rods 7 are provided and are arranged parallel to the axis of the battery mounting plate 3. They pass through the two limiting plates 2 and the multiple battery mounting plates 3 in sequence. The guide rods 7 are used to fix the battery mounting plates 3 so that the battery mounting plates 3 will not move radially due to external factors, and ensure that the battery will not tip over.

[0056] According to the battery fixing assembly provided in the embodiments of this utility model, such as Figure 2 and Figure 7 As shown, the battery mounting plate 3 is provided with a plurality of battery mounting bases 301, and the plurality of battery mounting bases 301 are arranged to extend to the edge of the battery mounting plate 3.

[0057] In this embodiment, the battery mounting plate 3 is provided with a plurality of battery mounting bases 301, and the plurality of battery mounting bases 301 extend to the edge of the battery mounting plate 3. Since the edge contour of the battery mounting plate 3 fits against the inner wall of the pressure-resistant chamber, and the battery mounting bases 301 extend to the edge of the battery mounting plate 3, batteries can be installed on the entire battery mounting plate 3. Moreover, the cross-section of the battery mounting plate 3 is consistent with the cross-sectional shape of the inner wall of the pressure-resistant chamber, and the sizes are interlocked, so that the maximum area inside the entire pressure-resistant chamber can be utilized, avoiding the waste of the limited space inside the pressure-resistant chamber.

[0058] According to the battery fixing assembly provided in the embodiments of this utility model, such as Figure 2 and Figure 7As shown, battery mounting plates 3 have battery mounting bases 301 on both sides, and the battery mounting bases 301 are arranged regularly and cover the entire battery mounting plate 3.

[0059] In some embodiments, the battery mounting plate 3 has a battery mounting base 301 on only one side, and the battery mounting bases 301 are irregularly arranged on the battery mounting plate 3, resulting in low utilization of the surface space of the battery mounting plate 3.

[0060] In this embodiment, battery mounting bases 301 are provided on both sides of the battery mounting plate 3, and the battery mounting bases 301 are regularly arranged to cover the entire battery mounting plate 3, thereby maximizing the space utilization on the battery mounting plate 3 and achieving maximum utilization of the space inside the pressure chamber.

[0062] There are at least two bow limit blocks 4013, which are evenly distributed and installed on the limit plate 2 near the bow end of the pressure tank body;

[0063] A stern-end limiting block 4014 is installed on a limiting plate 2 near the stern end of the main body of the pressure tank;

[0064] Among them, the first mounting hole 4011 axis of the bow end limiting block 4013 and the stern end limiting block 4014 is perpendicular to the limiting plate 2, and the second mounting hole 4012 axis is perpendicular to the main body of the pressure tank.

[0065] In this embodiment, the bow end limiting block 4013 connects the bow end side limiting plate 2 to the pressure tank body through the first mounting hole 4011 and the second mounting hole 4012, and the stern end limiting block 4014 connects the stern end side limiting plate 2 to the pressure tank body through the first mounting hole 4011 and the second mounting hole 4012, thereby fixing the battery in the pressure tank body.

[0066] According to an embodiment of this utility model, an underwater pressure-resistant tank is provided, such as... Figure 10 and Figure 11 As shown, the device includes the aforementioned battery fixing assembly and a pressure-resistant chamber body 8. The battery fixing assembly is installed inside the pressure-resistant chamber body 8 and connected to it.

[0067] In this embodiment, the battery pack fixing component is fitted inside the pressure tank body 8, and the outer contour of the battery pack fixing component is set to match the inner wall of the pressure tank body 8, so as to realize the maximum utilization of the internal area of ​​the pressure tank body 8, avoid the waste of the limited internal space, and effectively solve the problem that the connection between the underwater environment battery pack and the pressure tank in the prior art easily occupies the pressure tank space.

[0068] 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.
