Description

Technical Field

[0001] This application relates to the field of power distribution compartment technology, and more particularly to a disassembly and assembly device for an underwater pressure-resistant power distribution compartment. Background Technology

[0002] Currently, underwater vehicles extensively utilize pressure-resistant electrical distribution compartments as power distribution equipment. These compartments house circuit boards, circuit breakers, PLCs, relays, and other components. Watertight connection components are typically installed on the end caps of the underwater pressure-resistant electrical distribution compartments to enable electrical connectivity and communication between internal and external systems. During manufacturing, commissioning, and maintenance, it is usually necessary to remove the end caps and pull out the internal electrical distribution boards. However, the weight of underwater pressure-resistant electrical distribution compartments often exceeds human capabilities, making the process of disassembling and assembling the end caps complex and difficult. For reliable connections, the interior of the end caps typically houses non-removable cables, while the exterior of the end caps cannot always be removed due to commissioning requirements. Currently, disassembling and assembling end caps often involves using overhead cranes, which can easily damage cables, is inconvenient to operate, and is not feasible in many scenarios where overhead cranes are unavailable.

The descriptions in this section are merely illustrative and explanatory, and should not be construed as limiting the scope of protection of this application. Specifically, the described embodiments are only some embodiments of this application, not all embodiments.

[0020] It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0021] As mentioned in the background section, underwater vehicles currently extensively utilize underwater pressure-resistant electrical distribution compartments as power distribution equipment. These compartments house circuit boards, circuit breakers, PLCs, relays, and other components. Watertight connection components are typically installed on the end caps of the underwater pressure-resistant electrical distribution compartments to enable electrical connectivity and communication between internal and external systems. During manufacturing, commissioning, and maintenance, it is usually necessary to remove the end caps and pull out the internal electrical distribution boards. However, the weight of the underwater pressure-resistant electrical distribution compartments often exceeds human capabilities, making the process of disassembling and assembling the end caps complex and difficult. For reliable connections, the interior of the end caps typically houses non-removable cables, while the exterior of the end caps cannot always be removed due to commissioning requirements. Currently, disassembling and assembling end caps often involves using overhead cranes, which can easily damage cables, is inconvenient, and is not feasible in many scenarios.

[0022] To address the problems in the prior art, this embodiment provides a disassembly and assembly device 1000 for an underwater pressure-resistant power distribution compartment 2000. The following description, in conjunction with the appendix to the instruction manual, details the device's features. Figures 1-5 This application describes in detail an assembly and disassembly device 1000 for an underwater pressure-resistant power distribution compartment 2000, according to an embodiment of the present application.

[0023] like Figure 1 As shown, the disassembly and assembly equipment 1000 includes a first fixing frame 100 and a second fixing frame 200. (As indicated...) Figure 2 and Figure 3 As shown, the first mounting bracket 100 is used to secure the end cover 500 and the power distribution board 700 of the underwater pressure-resistant power distribution compartment 2000. Figure 4 and Figure 5 As shown, the second mounting bracket 200 is used to support the power distribution board 700 of the underwater pressure-resistant power distribution compartment 2000.

[0024] Specifically, such as Figure 1 As shown, the first fixing frame 100 has a first base 110, a first bracket 111, and a second bracket 112. Figure 2 and Figure 3 As shown, the first bracket 111 is detachably mounted to the first base 110. The first bracket 111 can be connected to the end cover 500 of the underwater pressure-resistant power distribution tank 2000 by bolts to fix the end cover 500 to the first fixing frame 100. Those skilled in the art will understand that the end cover 500 of the underwater pressure-resistant power distribution tank 2000 is connected to the cylinder 600 by multiple bolts. Therefore, when the first bracket 111 is connected to the end cover 500, several of the multiple bolts connecting the end cover 500 to the cylinder 600 can be removed, thereby allowing the end cover 500 to be bolted to the first bracket 111 through the bolt holes of the removed bolts. Furthermore, the bolted connection between the first bracket 111 and the end cover 500 prevents the end cover 500 from shifting position or tipping over during movement of the end cover 500 via the first fixing frame 100.

[0025] like Figure 4 and Figure 5 As shown, one end of the second bracket 112 is detachably connected to the first base 110, and the other end of the second bracket 112 is detachably connected to the power distribution board 700 of the underwater pressure-resistant power distribution compartment 2000. Therefore, after the first bracket 111 is connected and fixed to the end cover 500, the end cover 500 can be removed and moved, and then one end of the second bracket 112 can be connected to the first base 110, and the other end of the second bracket 112 can be connected to the power distribution board 700. This achieves the goal of fixing the end cover 500 through the first fixing bracket 100 and connecting it to the power distribution board 700.

[0026] like Figure 4 and Figure 5As shown, the second fixing frame 200 has two support platforms 210, which can be placed at intervals on both sides of the distribution board 700 in the width direction below the distribution board 700 to support the distribution board 700.

[0027] Therefore, after the first fixing frame 100 is connected to the power distribution board 700 and the power distribution board 700 is taken out from the underwater pressure-resistant power distribution chamber 2000, it can be placed under the power distribution board 700 from both sides of the width direction by the two support platforms 210 of the second fixing frame 200, and there is a gap between the two support platforms 210, which can provide more stable support for the power distribution board 700.

[0028] In addition, the design of using two support platforms 210 allows the two support platforms 210 to be placed on both sides of the distribution board 700 along its length, below the distribution board 700, without the need for cabling, and facilitates the placement and removal of the support platforms 210.

[0029] The disassembly and assembly device 1000 for an underwater pressure-resistant power distribution compartment 2000 provided in this application has a simple overall structure, occupies little space, and is easy to operate. It is suitable for disassembling and assembling the end cover 500 of the underwater pressure-resistant power distribution compartment 2000 in various environments. Manual operation is convenient, reducing labor costs. Furthermore, the end cover 500 is removed via the first fixing bracket 100, and then the power distribution board 700 is connected and removed. The power distribution board 700 is supported by the second fixing bracket 200. The overall operation is convenient and quick, and it also avoids damage to the internal cables of the underwater pressure-resistant power distribution compartment 2000. The end cover 500 and the power distribution board 700 can be removed during testing or debugging of the underwater pressure-resistant power distribution compartment 2000. Correspondingly, the reassembly of the end cover 500 and the power distribution board 700 back into the underwater pressure-resistant power distribution compartment 2000 is also easy and quick.

[0030] In some embodiments of this application, such as Figure 1 As shown, the first fixing frame 100 includes two first supports 111, which are spaced apart along the width direction of the first base 110 and perpendicular to the upper surface of the first base 110.

[0031] like Figure 2 and Figure 3 As shown, the side wall of the first bracket 111 is provided with two spaced fixing holes 1111 at positions corresponding to the bolt holes of the end cover 500, so that the end cover 500 can be connected to the first bracket 111 by passing bolts through the fixing holes 1111 of the first bracket 111 and the bolt holes of the end cover 500 in sequence.

[0032] Specifically, after the fixing hole 1111 of the first bracket 111 aligns with the bolt hole of the end cap 500, bolts are sequentially passed through the fixing hole 1111 and the bolt hole of the end cap 500 to stabilize the relative position between the first bracket 111 and the end cap 500. That is, the relative position between the end cap 500 and the first bracket 111 is fixed by the bolts passing through the fixing hole 1111 and the bolt hole of the end cap 500. Then, all remaining bolts connecting the end cap 500 and the cylinder 600 are removed, so that the movement of the first bracket 111 drives the synchronous movement of the end cap 500 until the end cap 500 is separated from the cylinder 600 and a gap is formed. After the end cap 500 is removed from the cylinder 600 and has separated from the cylinder 600 by a certain distance, rubber protective pads need to be added to the inner surface of the end cap 500 at the positions corresponding to the bolt holes. The inner surface of the end cap 500 is the surface of the end cap 500 facing the cylinder 600. Then, by using nuts to tighten the bolts on the inner surface of the end cap 500, the end cap 500 is stably connected to the first bracket 111.

[0033] It should be noted that the connection between the end cap 500 and the cylinder 600 requires a waterproof design; therefore, the surface of the end cap 500 facing the cylinder 600 has a waterproof layer. To prevent the nut from scratching the waterproof layer when tightening the bolt, a rubber protective pad is added to one side of the waterproof layer before the nut and bolt are connected. This protects the waterproof layer from being scratched or damaged by the nut.

[0034] like Figure 1 As shown, the cross-section of the first support 111 is L-shaped. Figure 3 As shown, the fixing hole 1111 is an oblong hole. The oblong shape allows for fine-tuning of the position after the bolt holes of the end cap 500 are connected to the fixing hole 1111. Both fixing holes 1111 are located on the sidewall of the surface of the first bracket 111 facing the end cap 500. The two fixing holes 1111 are spaced apart along the length of the first bracket 111 and are collinear. Therefore, each side of the first bracket 111 has two fixing holes 1111, and a single first bracket 111 is connected to the end cap 500 through these two fixing holes, ensuring a stable connection between the first fixing bracket 100 and the end cap 500. While the end cap 500 is bolted to the two first brackets 111, the lower part of the end cap 500 abuts against the upper surface of the first base 110, which limits the vertical position of the end cap 500.

[0035] Specifically, the first bracket 111 has an L-shaped cross-section and consists of two long plates connected by their long sides. One long plate faces the surface of the end cover 500, while the other long plate faces the circumferential surface of the end cover 500. Therefore, when the two first brackets 111 are connected to the end cover 500, the long plate facing the surface of the end cover 500 is in contact with the surface of the end cover 500, and the long plate facing the circumferential surface of the end cover 500 abuts against the circumferential surface of the end cover 500. This allows the two first brackets 111 to limit the width of the end cover 500.

[0036] In some embodiments of this application, a plurality of mounting holes 1112 are spaced apart on the upper surface of the first base 110 along its width direction. As mentioned above, the first bracket 111 and the first base 110 are detachably connected. The plurality of mounting holes 1112 in the width direction of the first base 110 allow the first bracket 111 to be connected to different mounting holes 1112, thereby adjusting the installation position between the first bracket 111 and the first base 110. Furthermore, both first brackets 111 can be adjusted to their installation position on the first base 110, thereby adjusting the spacing between the two first brackets 111 according to different sizes of end caps 500, ensuring that both first brackets can be connected to the end cap 500, and ensuring a stable connection between the end cap 500 and the first fixing frame 100.

[0037] like Figures 1-4 As shown, the first bracket 111 is also provided with a lifting hole 1113. Those skilled in the art will understand that the end cap 500 of the underwater pressure-resistant power distribution compartment 2000 is connected to the cylinder 600 by multiple bolts. The end cap 500 also has lifting screw holes on its surface. Therefore, the first bracket 111 provides a lifting hole 1113 corresponding to the position of the lifting screw holes on the surface of the end cap 500. By directly passing bolts through the lifting hole 1113 and the lifting screw holes on the surface of the end cap 500, the end cap 500 can be directly connected to the first bracket 111, making the connection more convenient and faster.

[0038] like Figure 1 , Figure 4 and Figure 5 As shown, the second bracket 112 includes two second connecting rods 1121. One end of the second connecting rod 1121 is detachably connected to the side wall of the first base 110, and the other end of the second connecting rod 1121 is detachably connected to the power distribution board 700. In other words, the second connecting rod 1121 is a detachable structure, which can be detachably connected to both the first base 110 and the power distribution board 700, making the overall structure of the disassembly and assembly equipment 1000 more flexible in use.

[0039] Furthermore, such as Figure 1 , Figure 4and Figure 5 As shown, the second connecting rod 1121 forms an angle with the horizontal plane. That is, the second connecting rod 1121 is a straight rod placed at an angle. By placing the second connecting rod 1121 at an angle, one end of which is connected to the first base 110, it can provide stable support. The other end of the second connecting rod 1121 is connected to the power distribution board 700, which facilitates the pulling out of the power distribution board 700 from the inside of the cylinder 600 and can prevent the cables inside the underwater pressure-resistant power distribution compartment 2000 from being damaged.

[0040] In some embodiments of this application, such as Figure 1 As shown, the first mounting bracket 100 also includes a handle 113 and multiple casters 114. The handle 113 is disposed on the first base 110, allowing for easy pushing and pulling of the first mounting bracket 100 to adjust its position. The multiple casters 114 are disposed on the lower surface of the first base 110 to support it. This provides support to the first base 110, and the multiple casters 114 facilitate position adjustment of the first mounting bracket 100, reducing resistance when moving it.

[0041] In addition, such as Figures 2-4 As shown, the outer surface of the end cap 500 has a cable insertion area, i.e. Figures 2-4 As those skilled in the art will understand, the cable insertion area on the outer surface of the end cap 500 in the R1 region has multiple connection interfaces. External cables connect to the internal cables of the underwater pressure-resistant power distribution compartment 2000 and the power distribution board 700, etc., through the connection interfaces in this region. Figure 3 As shown, after the handle 113 is connected to the first base 110, it does not block the cable insertion area R1, thus ensuring a stable and unobstructed connection between the external cable and the end cover 500.

[0042] Furthermore, the handle 113 and the first base 110 can be detachably connected, thereby avoiding obstruction of the cable insertion area R1 of the end cover 500 by removing the handle 113. In addition, the handle 113 can be replaced with other structural forms of handle 113 to adapt to different usage environments.

[0043] In some embodiments of this application, such as Figure 1 As shown, the first base 110 is an I-shaped structure frame with two first supports 111 on its crossbeam. The side wall of the first base 110 is connected to two second connecting rods 1121. Multiple casters 114 can be provided on the lower surface of the I-shaped structure of the first base 110. Thus, the multiple casters 114 can support the first base 110 and facilitate the movement of the first fixed frame 100.

[0044] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the second fixing frame 200 also includes a connector 230, the two ends of which are detachably connected to two support platforms 210, and the connector 230 is parallel to the horizontal plane. By connecting the two ends of the connector 230 to the two support platforms 210, the position between the two support platforms 210 is fixed. That is, the connector 230 restricts the movement of the two support platforms 230 in the width direction of the distribution board 700, preventing the position of the two support platforms 210 from shifting.

[0045] In other words, the connector 230 stabilizes the relative position between the two support platforms 210, preventing the support platforms 210 from shifting after placement, which would reduce the stability of the distribution board 700. Furthermore, the connector 230 is detachably connected to the support platforms 210, facilitating the placement and removal of the support platforms 210.

[0046] In some embodiments of this application, the connector 230 is a connecting plate, and the two ends of the connecting plate are respectively connected to two support platforms 210, thereby stabilizing the position of the two support platforms 210.

[0047] Furthermore, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the support platform 210 also includes a second base 212, and the two ends of the connector 230 are respectively connected to the two second bases 212 to stabilize the position of the two support platforms 210.

[0048] Furthermore, such as Figure 1 As shown, the support platform 210 includes a limiting member 211, which is disposed on the top surface of the support platform 210. The limiting member 211 includes a limiting plate 2111 and a plurality of balls 2112. The limiting plate 2111 can abut against the side of the power distribution board 700, and the balls 2112 are rolled to the bottom wall of the limiting plate 2111. The plurality of balls 2112 abut against the lower surface of the power distribution board 700.

[0049] Specifically, the limiting plate 2111 restricts the lateral movement of the distribution board 700, that is, the movement of the distribution board 700 in the width direction. This allows the distribution board 700 to move along its length. The ball bearings 2112, after the distribution board 700 is placed on the limiting member 211, facilitate the movement of the distribution board 700 along its length direction through the rolling of the ball bearings, thus facilitating the position adjustment of the distribution board 700.

[0050] In some embodiments of this application, the limiting plate 2111 is a fixed plate with an L-shaped cross-section, one of which is connected to the top surface of the support platform 210, and the other side of the limiting plate 2111 is perpendicular to the horizontal plane, which can limit the position of the distribution plate 700 on the side in the length direction of the distribution plate 700.

[0051] The disassembly and assembly equipment 1000 provided in this application solves the problem of complicated operation and high labor consumption when disassembling and installing the end cover 500 and the power distribution board 700 of the underwater pressure-resistant power distribution chamber 2000 through the first fixing frame 100 and the second fixing frame 200.

[0052] To facilitate understanding by those skilled in the art, the workflow of the disassembly and assembly device 1000 provided in this application is further as follows: like Figure 2 As shown, firstly, by appropriately adjusting the height of the rollers, the lower part of the circumferential surface of the end cap 500 abuts against the upper surface of the first base 110, thereby allowing the end cap 500 to be supported by the first base 110. The rollers can be casters. Those skilled in the art will understand that casters and similar roller structures have threads, allowing them to be threadedly connected to the first base 110. The lifting height of the caster relative to the overall structure is adjusted by regulating the tightness of the threads between the caster and the first base 110. By pushing the handle 113, the first fixing frame 100 is pushed to the corresponding position of the end cap 500 of the underwater pressure-resistant power distribution compartment 2000. At this time, the first fixing frame 100 is not equipped with the second connecting rod 1121. Remove the bolts that correspond to the fixing holes 1111 on the first bracket 111 from the multiple bolts connecting the end cap 500 and the cylinder 600. Then, use new bolts longer than the original bolts to pass through the fixing holes 1111 and the bolt holes on the end cap 500 where the removed bolts were found, thus fixing the position between the end cap 500 and the first fixing bracket 100. Next, connect a new nut to the new bolt, which is longer than the original bolt, leaving a gap between the new nut and the new bolt. After removing all the remaining original bolts connecting the end cap 500 and the cylinder 600, remove the new nuts from the new bolts to allow the end cap 500 to be completely detached from the cylinder 600.

[0053] By moving the first fixing frame 100, the end cap 500 moves synchronously with it, creating a gap between the first fixing frame 100 and the cylinder 600. At this time, a rubber protective pad is added to the inner surface of the end cap 500 corresponding to the bolt hole position. The inner surface of the end cap 500 is the surface of the end cap 500 facing the cylinder 600. A rubber protective pad is added to the inner side of the end cap 500 where it connects to the first bracket 111. Then, a new nut is tightened with a new bolt passing through the fixing hole 1111 and the bolt hole of the end cap 500, so that the end cap 500 and the first bracket 111 are stably connected.

[0054] It should be noted that the connection between the end cap 500 and the cylinder 600 requires a waterproof design; therefore, the surface of the end cap 500 facing the cylinder 600 has a waterproof layer. To prevent the nut from scratching the waterproof layer when tightening the bolt, a rubber protective pad is added to one side of the waterproof layer before the nut and bolt are connected. This protects the waterproof layer from being scratched or damaged by the nut.

[0055] Then continue to pull handle 113 to move the first fixed frame 100 until the redundant cables in the underwater pressure-resistant power distribution compartment 2000 are pulled out, and then connect one end of the second connecting rod 1121 to the first base 110, and the other end of the second connecting rod 1121 to the power distribution board 700.

[0056] It should be noted here that the underwater pressure-resistant power distribution chamber 2000 has a power distribution board 700 inside the cylinder 600. The power distribution board 700 is connected to the end cover 500 by cables, which are the redundant cables mentioned above.

[0057] Continue pulling the first fixing frame 100 to pull the power distribution board 700 out of the cylinder 600. Then, place the two second support platforms 210 under the power distribution board 700 from both sides of its width direction. Connect the two support platforms 210 through the two ends of the connector 230 to fix their positions. That is, the connector 230 restricts the movement of the two support platforms 210 in the width direction of the power distribution board 700, preventing positional shifts. The power distribution board 700 is placed on the limiting member 211 of the support platform 210. The limiting member 211 restricts the movement of the power distribution board 700 from both sides, while the ball bearings 2112 facilitate the movement of the power distribution board 700.

[0058] When it is necessary to reassemble the end cap 500 and the power distribution plate 700 back into the underwater pressure-resistant power distribution compartment 2000, the power distribution plate 700 and the end cap 500 are pushed towards the cylinder 600 by moving the first fixing bracket 100. When the power distribution plate 700 is pushed into the cylinder 600 and can be stably supported by the inside of the cylinder 600, the connector 230 is removed, and the two support platforms 210 are taken out from both sides. After the power distribution plate 700 is put back into the cylinder 600, the second connecting rod 1121 is removed, and the first fixing bracket 100 is pushed further to make the end cap 500 contact the cylinder 600, and the bolt holes of the end cap 500 that were not connected to the first bracket 111 are reconnected to the cylinder 600 by bolts. Then the bolts connecting the end cap 500 to the first bracket 111 are removed, so that the end cap 500 is connected to the cylinder 600 through multiple bolt holes.

[0059] Therefore, the process of removing the end cover 500 and the power distribution board 700 by disassembling and assembling equipment 1000, and the process of assembling the end cover 500 and the power distribution board 700 by disassembling and assembling equipment 1000 are as described above.
