Technical Field

[0001] This utility model relates to the field of modular power station technology, specifically to a connection structure and a modular power station. Background Technology

[0002] Existing modular power stations are mainly used to provide emergency power in situations where mains power is unavailable, and are widely used in radar communications and power restoration. Current modular power stations all use ordinary cabins, with the cabin panels mostly fixed by bolts, resulting in limited connection strength. Therefore, there is an urgent need for a new connection structure and modular power station to solve these problems. Utility Model Content

[0003] To address the technical problem that existing modular power station modules often use bolted connections for fixing, resulting in limited connection strength, this invention provides a connection structure and modular power station. By setting up a connection structure, specifically by incorporating container corner fittings and three corner fittings, the first, second, and third panels are further stably connected, effectively improving the connection strength of the first, second, and third panels, and ultimately enhancing the overall connection strength of the modular power station module.

[0004] This utility model provides a connection structure, which is fixedly installed at a notch in a first plate, a second plate, and a third plate that are fixedly connected to each other and perpendicular to each other. The connection structure includes a container corner piece and three corner pieces. The three corner pieces are respectively fixedly installed on one of the top corners of the first plate, the second plate, and the third plate. The three corner pieces are fixedly connected to each other and perpendicular to each other. The container corner piece is fixedly installed between the three corner pieces.

[0005] Furthermore, the ends of the first plate and the second plate are fixedly connected and perpendicular to each other, and the two sides of the third plate are fixedly connected to the first plate and the second plate respectively, and the third plate is perpendicular to the first plate and the second plate.

[0006] Furthermore, each corner piece includes an L-shaped inner plate and an L-shaped outer plate. The L-shaped inner plate and L-shaped outer plate of the first corner piece are welded and fixedly disposed on one of the apex corners of the first plate, with both ends of the L-shaped outer plate extending to the outside of the first plate. The L-shaped inner plate and L-shaped outer plate of the second corner piece are welded and fixedly disposed on one of the apex corners of the second plate, with both ends of the L-shaped outer plate extending to the outside of the second plate. The L-shaped inner plate and L-shaped outer plate of the third corner piece are welded and fixedly disposed on one of the apex corners of the third plate, with both ends of the L-shaped outer plate extending to the outside of the third plate. The corner pieces, including the L-shaped inner plate and L-shaped outer plate, have high inherent strength. The three corner pieces enhance the connection strength when the first, second, and third plates are connected.

[0007] Furthermore, one end of the L-shaped outer plate on the first plate is welded and fixedly connected to one end of the L-shaped outer plate on the second plate, and the other end of the L-shaped outer plate on the first plate is welded and fixedly connected to one end of the L-shaped outer plate on the third plate. The other end of the L-shaped outer plate on the second plate is also welded and fixedly connected to the other end of the L-shaped outer plate on the third plate.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1, as Figures 1-8 As shown, a connecting structure is fixedly installed at a notch in a first plate 1, a second plate 2, and a third plate 3 that are fixedly connected to each other and perpendicular to each other. The first plate 1, the second plate 2, and the third plate 3 can be used for connecting frame structures such as modular power stations. The connecting structure includes a container corner piece 4 and three corner pieces 5. The three corner pieces 5 are respectively fixedly installed at one of the top corners of the first plate 1, the second plate 2, and the third plate 3, and are fixedly connected to each other and perpendicular to each other. The container corner piece 4 is fixedly installed between the three corner pieces 5. The mechanism of the container corner piece 4 is existing technology and will not be described in detail here. Firstly, the first plate 1, the second plate 2, and the third plate 3 are fixedly connected to each other and perpendicular to each other. A notch is formed between one of the top corners of the first plate 1, the second plate 2, and the third plate 3. The connecting structure is fixed at this notch, thereby further stabilizing the connection between the first plate 1, the second plate 2, and the third plate 3. Specifically, three corner pieces 5 are welded and fixedly installed on one of the top corners of the first plate 1, the second plate 2, and the third plate 3, respectively. Then, container corner pieces 4 are welded and fixedly installed between the three corner pieces 5, ultimately achieving a more stable connection between the first plate 1, the second plate 2, and the third plate 3. The container corner pieces 4 and the three corner pieces 5 work together to effectively improve the connection strength when the first plate 1, the second plate 2, and the third plate 3 are connected.

[0032] The connection structure in this embodiment, by setting container corner pieces 4 and three corner pieces 5, further stabilizes the connection between the first plate 1, the second plate 2 and the third plate 3, effectively improving the connection strength of the first plate 1, the second plate 2 and the third plate 3.

[0033] In one possible implementation, the ends of the first plate 1 and the second plate 2 are fixedly connected and perpendicular to each other. The two sides of the third plate 3 are respectively fixedly connected to the first plate 1 and the second plate 2, and the third plate 3 is perpendicular to the first plate 1 and the second plate 2. Currently, the panels of modular power station hulls are mostly fixed with screws, which tend to rust over time. It is worth noting that the first plate 1 and the second plate 2 are fixed with riveting, and the third plate 3 is also fixed with both the first plate 1 and the second plate 2 using riveting. Riveting achieves a stable connection, ensures aesthetics, and also solves the problem of screw rusting.

[0034] In one possible implementation, each corner piece 5 includes an L-shaped inner plate 51 and an L-shaped outer plate 52, wherein the L-shaped inner plate 51 is located inside or below the L-shaped outer plate 52. The L-shaped inner plate 51 and L-shaped outer plate 52 of the first corner piece 5 are welded and fixedly disposed on one of the top corners of the first plate body 1, and both ends of the L-shaped outer plate 52 extend to the outside of the first plate body 1. The gap between the L-shaped inner plate 51 and L-shaped outer plate 52 and the first plate body 1 is left to facilitate subsequent welding. The L-shaped inner plate 51 and L-shaped outer plate 52 of the second corner piece 5 are welded and fixedly disposed on one of the top corners of the second plate body 2, and both ends of the L-shaped outer plate 52 extend to the outside of the second plate body 2. The L-shaped inner plate 51 and L-shaped outer plate 52 of the third corner piece 5 are welded and fixedly disposed on one of the top corners of the third plate body 3, and both ends of the L-shaped outer plate 52 extend to the outside of the third plate body 3. The corner piece 5 includes an L-shaped inner plate 51 and an L-shaped outer plate 52. The corner piece 5 itself has high strength, and the three corner pieces 5 improve the connection strength when the first plate 1, the second plate 2, and the third plate 3 are connected. The corner piece 5 uses a combination of L-shaped inner plate 51 and L-shaped outer plate 52, which occupies little space, thereby reducing the volume of the first plate 1, the second plate 2, and the third plate 3 after being fixed together, thus reducing a certain amount of weight.

[0035] In one possible implementation, one end of the L-shaped outer plate 52 on the first plate 1 is welded and fixedly connected to one end of the L-shaped outer plate 52 on the second plate 2, and the other end of the L-shaped outer plate 52 on the first plate 1 is welded and fixedly connected to one end of the L-shaped outer plate 52 on the third plate 3. The other end of the L-shaped outer plate 52 on the second plate 2 is also welded and fixedly connected to the other end of the L-shaped outer plate 52 on the third plate 3. The L-shaped outer plates 52 of the three corner pieces 5 further securely connect the first plate 1, the second plate 2, and the third plate 3 together.

[0036] As one possible implementation, each L-shaped inner plate 51 has a first connecting plate 511 fixedly disposed on both sides, perpendicular to it; and each L-shaped outer plate 52 has a second connecting plate 521 fixedly disposed on both sides, perpendicular to it. The first connecting plates 511 and 521 on the first plate 1 are welded to the first plate 1 to increase the stability of the connection between the L-shaped inner plate 51 and the L-shaped outer plate 52 and the first plate 1. Similarly, the first connecting plates 511 and 521 on the second plate 2 are welded to the second plate 2 to increase the stability of the connection between the L-shaped inner plate 51 and the L-shaped outer plate 52 and the second plate 2. Finally, the first connecting plates 511 and 521 on the third plate 3 are welded to the third plate 3 to increase the stability of the connection between the L-shaped inner plate 51 and the L-shaped outer plate 52 and the third plate 3.

[0037] Preferably, both the first connecting plate 511 and the second connecting plate 521 are provided with through holes. When the three corner pieces 5 are respectively welded and fixed to one of the top corners of the first plate 1, the second plate 2 and the third plate 3, the first connecting plate 511 and the second connecting plate 521 of each corner piece 5 can also be riveted to the first plate 1, the second plate 2 and the third plate 3 through their respective through holes, further improving the connection strength during connection.

[0038] As one possible implementation, L-shaped edging 6 is fixedly provided on the exterior of the first plate 1 and the second plate 2, the first plate 1 and the third plate 3, and the second plate 2 and the third plate 3 by first rivets; L-shaped inner pressure strips 7 are fixedly provided on the interior of the first plate 1 and the second plate 2, the first plate 1 and the third plate 3, and the second plate 2 and the third plate 3 by second rivets. The purpose of providing L-shaped edging 6 and L-shaped inner pressure strips 7 is to further improve the structural strength of the connection between the first plate 1, the second plate 2, and the third plate 3. Currently, the panels of modular power station hulls are mostly fixed with bolts, which will rust after long-term use. The L-shaped edging 6 is fixed with first rivets, and the L-shaped inner pressure strip 7 is fixed with second rivets. The riveting and fixing with first and second rivets achieves a stable connection, ensures aesthetics, and also solves the problem of screw rusting.

[0039] Preferably, the ends of the L-shaped edging 6 are welded and fixed to the container corner fittings 4 to improve the stability of the connection. Furthermore, the contact points between the L-shaped edging 6 and the first plate 1, the second plate 2, and the third plate 3 are sealed.

[0040] In one possible implementation, the end of the L-shaped edging 6 located between the first plate 1 and the second plate 2 covers the outer side of the ends of the two L-shaped outer plates 52 (i.e., on the first plate 1 and the second plate 2); the end of the L-shaped edging 6 located between the first plate 1 and the third plate 3 covers the outer side of the ends of the two L-shaped outer plates 52 (i.e., on the first plate 1 and the third plate 3); and the end of the L-shaped edging 6 located between the second plate 2 and the third plate 3 covers the outer side of the ends of the two L-shaped outer plates 52 (i.e., on the second plate 2 and the third plate 3). For example, the middle position of the first L-shaped edging 6 is riveted and fixed to the outside between the first plate 1 and the second plate 2, and the end of the first L-shaped edging 6 is welded and fixed to the first plate 1 and the second plate 2, covering the outer side of the ends of the two L-shaped outer plates 52 (i.e., at the welding position of the ends of the two L-shaped outer plates 52). Similarly, the second L-shaped edging 6 is welded and fixed to the first plate 1 and the third plate 3, covering the outer sides of the ends of the two L-shaped outer plates 52. The third L-shaped edging 6 is welded and fixed to the second plate 2 and the third plate 3, covering the outer sides of the ends of the two L-shaped outer plates 52. The ends of the L-shaped edging 6 protect the outer sides of the ends of the two fixedly connected L-shaped outer plates 52, ensuring both stability during connection and aesthetics.

[0041] In one possible implementation, a first L-shaped decorative panel 11, a second L-shaped decorative panel 21, and a third L-shaped decorative panel 31 are respectively fixedly disposed at one of the top corners of the first plate 1, the second plate 2, and the third plate 3. The first L-shaped decorative panel 11 is flush with the surface of the first plate 1, the second L-shaped decorative panel 21 is flush with the surface of the second plate 2, and the third L-shaped decorative panel 31 is flush with the surface of the third plate 3. The first L-shaped decorative panel 11, the second L-shaped decorative panel 21, and the third L-shaped decorative panel 31 are all located between two L-shaped edging 6. The first L-shaped decorative panel 11, the second L-shaped decorative panel 21, and the third L-shaped decorative panel 31 respectively protect the top corners of the first plate 1, the second plate 2, and the third plate 3, ensuring aesthetic appeal.

[0042] Preferably, the first L-shaped decorative panel 11 and the first panel 1, the second L-shaped decorative panel 21 and the second panel 2, and the third L-shaped decorative panel 31 and the third panel 3 can be filled with sealant and wood, and then fixed with rivets.

[0043] Example 2, as Figures 9-11As shown, a modular power station includes a cabin body and a connecting structure as described in any of the above embodiments. The cabin body includes two first plates 1, a second plate 2, and a third plate 3. The two first plates 1 are fixedly disposed at both ends of one of the third plates 3, and the two second plates 2 are fixedly disposed on both sides of one of the third plates 3. The two first plates 1 and the two second plates 2 are fixedly connected. The third plate 3 is fixedly disposed on top of the two first plates 1 and the two second plates 2. The two first plates 1, the two second plates 2, and the third plates 3 are symmetrically arranged, and each of the first plates 1, the second plates 2, and the third plates 3 is perpendicular to each other in pairs. There are eight connecting structures, which are not fully shown in this embodiment. Each connecting structure is fixedly disposed at a notch in one of the first plates 1, the second plates 2, and the third plates 3. Each of the two adjacent sides of each third plate 3 is fixedly connected to one of the first plates 1 and the second plates 2. There are a total of eight notches in the two first plates 1, the second plates 2, and the third plates 3.

[0044] In this implementation, one first plate 1 is set as the front compartment plate of the modular power station, and the other first plate 1 is set as the rear compartment plate of the modular power station; one second plate 2 is set as the right compartment plate of the modular power station, and the other second plate 2 is set as the left compartment plate of the modular power station; one third plate 3 is set as the top compartment plate of the modular power station, and the other third plate 3 is set as the bottom compartment plate of the modular power station.

It should be noted that the front and rear panels are the same size, the right and left panels are the same size, and the bottom and top panels are the same size. However, the front and rear panels, the right and left panels, as well as the top and bottom panels can be fitted with windows of various shapes according to subsequent needs to facilitate the assembly of other components (such as louvers).

[0046] In this embodiment, there are eight connecting structures, that is, there are eight container corner pieces 4 and twenty-four corner pieces 5.

It should be noted that during assembly, if the first connecting structure (three L-shaped edgings 6) is installed between the front and right hatches, between the front and top hatches, and between the right and top hatches, then when installing the second connecting structure between the front and left hatches, between the left and top hatches, and between the front and top hatches, since the front and top hatches already have L-shaped edgings 6, the second connecting structure can be reduced by one L-shaped edging 6.

[0048] Typically, both ends of each L-shaped edging 6 cover the outer side of the L-shaped outer plate 52 of the two connecting structures.

[0049] Eight first L-shaped decorative panels 11, eight second L-shaped decorative panels 21, and eight third L-shaped decorative panels 31 are provided.

[0050] Specifically, each of the first plate 1, second plate 2, and third plate 3 is fixed at one of its apex corners by a connecting structure. That is, three corner pieces 5 are welded and fixed to one of the apex corners of each of the first plate 1, second plate 2, and third plate 3. Then, each container corner piece 4 is welded and fixed between the three corner pieces 5, and the two first plates 1, second plate 2, and third plate 3 are stably connected.

Finally, the overall connection strength of the modular power station body is greatly improved.

[0051] The modular power station in this embodiment effectively improves the overall connection strength of the modular power station body by setting up a connection structure.

[0052] Preferably, when the top deck panel is fixedly connected to the front deck panel, aft deck panel, right deck panel, and left deck panel, the top deck panel side overlaps the front deck panel, aft deck panel, right deck panel, and left deck panel. Preferably, when the bottom deck panel is fixedly connected to the front deck panel, aft deck panel, right deck panel, and left deck panel, the bottom deck panel side is fixedly disposed inside the front deck panel, aft deck panel, right deck panel, and left deck panel.
