DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings). In the description of the present invention, it should be understood that the orientation or position relationship indicated by the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc. are based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0020] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0021] like Figure 1-Figure 11 As shown, a splicable power prefabricated cabin includes a sub-cabin body 100 and a folding door 200, there are multiple sub-cabin bodies 100, the sub-cabin body 100 is square, and connecting grooves 110 are provided on both sides of the length direction of the sub-cabin body 100, and the connecting grooves 110 are penetrated to the inside of the sub-cabin body 100, and the folding door 200 is slidably arranged in the connecting grooves 110, and the folding door 200 has a straight-line unfolding state. When the folding door 200 is in the straight-line unfolding state, the folding door 200 blocks the connecting groove 110, and the folding door 200 also has a first folding state. When the folding door 200 is in the first folding state, the folding part of the folding door 200 is arranged in a folding line shape, and the folding door 200 can switch between the straight-line unfolding state and the first folding state. When two sub-cabin bodies 100 are spliced, the folding doors 200 in the first folding state corresponding to the two sub-cabin bodies 100 have a first connection form. When in the first connection form, the folding doors 200 in the first folding state are connected in a completely overlapping form.

[0022] When splicing (taking the splicing of two sub-cabins 100 together as an example), the staff first adjusts the folding doors 200 corresponding to the two sub-cabins 100, so that the folding door 200 corresponding to one connecting groove 110 of the two sub-cabins 100 is in a straight-line unfolded state, and the other folding door 200 is in a first folded state. Next, the sides of the folding doors 200 in the first folded state of the two sub-cabins 100 are close to each other until the two folding doors 200 in the first folded state of the two sub-cabins 100 are completely overlapped. At this time, the two folding doors 200 in the first folded state are in a first connection form. Next, after the positions of the folding doors 200 in the first folded state are fixed, the two sub-cabins 100 cannot move relative to each other in their length direction. At this time, when the two sub-cabins 100 are subjected to a force from the length direction of the sub-cabins 100, the two sub-cabins 100 will not move relative to each other under the connection of the folding doors 200, so that no gap will be caused at the connection between the two sub-cabins 100, thereby ensuring the long-term normal use of the power prefabricated cabin.

[0023] It can be understood that, because in the first connection form, the two folding doors 200 in the first folded state completely overlap, the connecting groove 110 has a larger connecting space at its location, which can accommodate larger electrical equipment or electrical maintenance equipment, thereby facilitating the further assembly of internal electrical facilities in the electrical prefabricated cabin.

[0024] It should also be noted that, in order to facilitate the two sub-cabin bodies 100 to be close to each other, universal wheels can be provided at the bottom of the sub-cabin bodies 100 .

[0025] In a further embodiment, Figure 6 and Figure 7 As shown, when two sub-cabin bodies 100 are spliced ​​together, the folding doors 200 corresponding to the two sub-cabin bodies 100 in the first folded state also have a second connection form. When in the second connection form, the folding doors 200 in the first folded state are connected in a partially overlapping form.

[0026] When splicing (taking the splicing of two sub-cabins 100 together as an example), the staff first adjusts the folding doors 200 corresponding to the two sub-cabins 100 so that one folding door 200 is in a straight-line unfolded state and the other folding door 200 is in a first folded state. Next, the relative positions of the folding parts of the folding doors 200 corresponding to the two sub-cabins 100 are adjusted so that the folding parts of the two folding doors 200 in the first folded state are misaligned in the length direction of the sub-cabins 100. Next, the sides of the folding doors 200 of the two sub-cabins 100 in the first folded state are brought closer to each other until the two sub-cabins 100 are in the first folded state. The two folding doors 200 partially overlap, and at this time, the folding doors 200 in the first folded state corresponding to the two sub-cabin bodies 100 form a second connection form. Next, after the position of the folding door 200 in the first folded state is fixed, the two sub-cabin bodies 100 cannot move relative to each other in their length direction. At this time, the two folding doors 200 partially overlap, so the connection width at the connecting groove 110 corresponding to the two folding doors 200 is reduced, and the connection width can only accommodate the basic work needs of the power maintenance personnel. Therefore, the second connection form is suitable for the situation where the power equipment inside the sub-cabin body 100 does not need to be connected and installed after the two sub-cabin bodies 100 are spliced.

[0027] In a further embodiment, Figure 8 As shown, when two sub-cabin bodies 100 are spliced ​​together, the folding doors 200 in the first folded state corresponding to the two sub-cabin bodies 100 also have a third connection form. When in the third connection form, the folding doors 200 in the first folded state are connected in a non-overlapping form.

[0028] When splicing (taking the splicing of two sub-cabin bodies 100 together as an example), the staff first adjusts the folding doors 200 corresponding to the two sub-cabin bodies 100, so that one folding door 200 is in a straight-line unfolded state and the other folding door 200 is in a first folded state, and then adjusts the relative positions of the folding parts of the folding doors 200 corresponding to the two sub-cabin bodies 100, so that the folding parts of the two folding doors 200 in the first folded state are completely misaligned in the length direction of the sub-cabin bodies 100, and the two folding doors 200 are in a position where the ends close to each other can be connected together, and then the sides of the folding doors 200 in the first folded state of the two sub-cabin bodies 100 are close to each other until the two sub-cabin bodies 100 are close to each other. The cabin bodies 100 are in contact with each other, and at this time the staff connects the ends of the folding doors 200 in the first folded state that are close to each other together, and at this time the folding doors 200 in the first folded state form a third connection form, and then fix the two folding doors 200 in the first folded state, and at this time the two sub-cabin bodies 100 are limited in their length direction and cannot move relative to each other. At this time, since the ends of the two folding doors 200 are connected together, when the two sub-cabin bodies 100 are subjected to forces from the length direction or width direction of the sub-cabin bodies 100, the two sub-cabin bodies 100 will not move relative to each other and cause gaps at the connection between the two sub-cabin bodies 100, thereby ensuring the long-term normal use of the power prefabricated cabin. The connecting space at the connecting groove 110 corresponding to the two folding doors 200 in the third connection form is completely blocked by the folding door 200, which is equivalent to forming a zigzag "wall" between the two sub-cabins 100. This not only connects the two sub-cabins 100 together and enhances the connection stability, but also reflects the radiation waves through the zigzag "wall" to weaken the interaction between the electronic components inside the two sub-cabins 100.

[0029] In a further embodiment, Figure 5 and Figure 7As shown, the folding door 200 includes a short door 210, a first middle door 220 and a first rotating door 230. A rotating shaft 240 is arranged at the middle position of the first rotating door 230. The upper and lower groove surfaces of the connecting groove 110 are both provided with rotating holes 130. The rotating shaft 240 is rotatably connected in the rotating hole 130. Both ends of the first rotating door 230 are hinged with the first middle door 220. One end of the first middle door 220 away from the first rotating door 230 is hinged with the short door 210. One end of the short door 210 away from the first middle door 220 is provided with a first hinged sliding column 251. The middle position of the first middle door 220 A first hinge slide column 251 is also provided, and the upper and lower groove surfaces of the connecting groove 110 are provided with a first guide groove 121 along the length direction of the sub-cabin body 100. The center of the rotating hole 130 is located on the center line of the width direction of the first guide groove 121. The first hinge slide column 251 is slidably connected in the first guide groove 121. There are multiple rotating holes 130, and the multiple rotating holes 130 are arranged at intervals along the length direction of the first guide groove 121, so as to be rotatably connected with different rotating holes 130 through the rotating shaft 240 to adjust the position of the rotating shaft 240 of the folding door 200 under different connection forms.

[0030] In the initial state, the folding door 200 is in a straight-line unfolded state, and the rotating shaft 240 is rotatably connected in the rotating hole 130. When the folding door 200 needs to be switched from the straight-line unfolded state to the first folded state, the staff pulls the first hinge slide 251 to make the first hinge slide 251 move along the first guide groove 121 toward the direction close to the rotating shaft 240. At this time, the distance between the first hinge slides 251 at the ends of the two short doors 210 gradually decreases, and the angles between the short doors 210 and the first middle door 220, and between the first middle door 220 and the first rotating door 230 gradually decrease. The length of the folding door 200 in the length direction of the sub-cabin body 100 decreases. When the distance between the first hinge slides 251 at the ends of the two short doors 210 gradually decreases to a preset distance, the folding door 200 switches from the straight-line unfolded state to the first folded state.

[0031] When two sub-cabin bodies 100 are spliced, if the folding doors 200 in the first folded state corresponding to the two sub-cabin bodies 100 are in the first connection form, the two sub-cabin bodies 100 are moved closer to each other until the two folding doors 200 in the first folded state completely overlap.

[0032] When two sub-cabin bodies 100 are spliced, if the folding doors 200 corresponding to the two sub-cabin bodies 100 in the first folding state are in the second connection form or the third connection form, it is necessary to first lift the rotating shaft 240 so that the rotating shaft 240 moves out of the current rotating hole 130, and then push the rotating shaft 240 along the first guide groove 121 so that the rotating shaft 240 moves to the rotating hole 130 corresponding to the second connection form or the third connection form, and then pull the first hinge slide column 251 so that the first hinge slide column 251 moves along the first guide groove 121 toward the direction close to the rotating shaft 240. At this time, the distance between the first hinge slide columns 251 connected at the ends of the two short doors 210 gradually decreases. When the distance between the first hinge slide columns 251 connected at the ends of the two short doors 210 gradually decreases to the preset distance, the folding door 200 switches from the unfolded state to the first folded state.

[0033] When two sub-cabin bodies 100 are spliced, if the connection form of the folding door 200 is the first connection form or the second connection form, the two sub-cabin bodies 100 can still move away from each other at this time. Therefore, it is also necessary to make the folding door 200 in the first connection form or the second connection form able to limit the two sub-cabin bodies 100 from moving away from each other in the width direction. To solve this problem, in a further embodiment, as Figure 5 and Figure 7 As shown, the sides of the short door 210, the first middle door 220 and the first rotating door 230 are all stamped with limiting grooves 260. When the folding parts of the folding door 200 overlap, the limiting grooves 260 corresponding to the overlapping parts of the folding door 200 overlap one by one.

[0034] When the folding parts of the folding door 200 overlap, they include complete overlap and partial overlap. At this time, since the short door 210, the first middle door 220 and the first rotating door 230 are all in an inclined state, when the sub-cabin bodies 100 are subjected to a force in the width direction that attempts to move them away from each other, the limiting grooves 260 of the overlapping parts of the folding door 200 restrict each other, making it impossible for the two sub-cabin bodies 100 to be separated, thereby ensuring that when the two sub-cabin bodies 100 are subjected to a force in the width direction, no gap will appear at the connection, thereby ensuring the normal use of the power prefabricated cabin.

[0035] It should be supplemented that, in order to facilitate the connection of the folding doors 200 corresponding to the two sub-cabin bodies 100 in the first connection form or the second connection form, before the two sub-cabin bodies 100 approach each other, the folding length of one of the folding doors 200 can be made slightly larger than the folding length corresponding to the first folding state, and the folding length of the other folding door 200 can be made slightly smaller than the folding length corresponding to the first folding state. When the two sub-cabin bodies 100 approach each other until the limiting grooves 260 contact each other, the folding lengths of the two folding doors 200 are adjusted to the length corresponding to the first folding state. In this process, the two limiting grooves 260 contacting each other are gradually adjusted to completely overlap.

[0036] It should also be added that when the length of the connecting groove 110 is very long, it is necessary to connect multiple folding doors 200 together, and make the first hinged slide columns 251 corresponding to the multiple folding doors 200 slidably connected in the same first guide groove 121, so that the length of the assembled folding door 200 can adapt to the length of the connecting groove 110.

[0037] It should also be noted that the diameter of the rotating hole 130 should be slightly smaller than the diameter of the first articulated slide post 251 . This is to prevent the first articulated slide post 251 from accidentally connecting to the rotating hole 130 when the first articulated slide post 251 slides in the first guide groove 121 .

[0038] In a further embodiment, a threaded hole is opened on the outer side of the sub-cabin body 100, and a top screw is threadedly connected to the threaded hole. The top screw is used to limit the first hinged slide column 251 from sliding along the first guide groove 121 when the folding door 200 is in the first folding state.

[0039] It should be supplemented that there are multiple threaded holes, and the multiple threaded holes correspond to the positions of the first hinge sliding column 251 in the first connection form, the second connection form, and the third connection form respectively.

[0040] When in use, if the folding door 200 is in any one of the first connection form, the second connection form or the third connection form, after the folding door 200 switches to the first folding form, the top screw is screwed into the threaded hole so that the top screw abuts against the first hinged slide column 251, and the pre-tightening force between the first hinged slide column 251 and the top screw is used to limit the movement of the first hinged slide column 251 along the first hinged slide column 251.

[0041] In other embodiments, Fig. 9 and Fig.10As shown, the folding door 200 also has a second folding state. When in the second folding state, the folding portion of the folding door 200 is in a wedge groove shape. When the two sub-cabin bodies 100 are spliced, the connection form of the folding doors 200 in the second folding state corresponding to the two sub-cabin bodies 100 is a third connection form. When in the third connection form, the folding portions of the folding door 200 in the second folding state are buckled with each other. The folding door 200 includes a second intermediate door 270, a second rotating door 280 and a sliding door 290. Both ends of the second intermediate door 270 are hinged to the second rotating door 280, and the end of the second rotating door 280 away from the second intermediate door 270 is hinged to the sliding door 290. The hinge between the second rotating door 280 and the second intermediate door 270 and the end of the sliding door 290 away from the second rotating door 280 are both provided with a second hinge slide column 252, and the upper and lower groove surfaces of the connecting groove 110 are both provided with a second guide groove 122 along the length direction of the sub-cabin body 100, and the second hinge slide column 252 is slidably connected in the second guide groove 122.

[0042] In the initial state, the folding door 200 is still in a straight-open state; During the splicing (taking the splicing of two sub-cabin bodies 100 together as an example), the staff first adjusts the folding doors 200 corresponding to the two sub-cabin bodies 100, so that the folding door 200 corresponding to one connecting groove 110 of the folding door 200 is in a straight-line unfolded state, and the folding door 200 corresponding to the other connecting groove 110 of the folding door 200 is in a second folded state, that is, the folding portion of the folding door 200 corresponding to the other connecting groove 110 is in a wedge groove shape. It should be noted here that for the folding portions of the two folding doors 200, the angle between the second rotating door 280 and the sliding door 290 corresponding to one of the folding doors 200 should be greater than the angle between the second rotating door 280 and the sliding door 290 corresponding to the other folding door 200. Next, the sides of the folding doors 200 of the two sub-cabin bodies 100 in the second folded state are brought closer to each other until the wedge groove of one folding door 200 is located at the other The inner side of the wedge groove of the folding door 200, then the second hinged slide column 252 corresponding to the folding door 200 with a larger angle between the second rotating door 280 and the sliding door 290 is fixed in position, and then the second rotating door 280 is pulled so that the two second rotating doors 280 move away from each other. At this time, the abutment pressure between the second rotating door 280 corresponding to the current folding door 200 and the second hinged slide column 252 corresponding to the other folding door 200 increases. When the abutment pressure increases to a preset value, the second hinged slide column 252 corresponding to the current folding door 200 is fixed in position. At this time, there is no need to open a limiting groove 260. Only through the interaction of the two wedge grooves, when the two sub-cabin bodies 100 are subjected to forces from their length direction or width direction, it can be ensured that the two sub-cabin bodies 100 will not move relative to each other, thereby ensuring that no gaps will appear at the connection between the sub-cabin bodies 100, thereby ensuring the normal use of the power prefabricated cabin.

[0043] In a further embodiment, Figure 1 and 11 As shown, connecting blocks 300 are provided at the four corners of the upper end of the sub-cabin body 100, and connecting holes 310 are provided on the two side surfaces of the connecting block 300 perpendicular to the length direction of the sub-cabin body 100. When two sub-cabin bodies 100 are spliced ​​together, connecting components 400 are provided in the two connecting holes 310. The connecting components 400 are used to connect the two sub-cabin bodies 100 and make the upper and lower end surfaces of the two sub-cabin bodies 100 flush.

[0044] The connection assembly 400 is provided to make the upper and lower end surfaces of the sub-cabin body 100 flush, so that the ground inside the sub-cabin body 100 is flush.

[0045] In a further embodiment, Fig.11As shown, the connecting assembly 400 includes a hollow tapered tube 410, a screw rod 420 and a nut 430. The inner circumference of the hollow tapered tube 410 is rotationally connected to the screw rod 420, the outer circumference of the hollow tapered tube 410 is rotationally connected in the connecting hole 310, the nut 430 is threadedly connected to the screw rod 420, and the outer dimensions of the connecting hole 310 are compatible with the outer dimensions of the hollow tapered tube 410.

[0046] When in use, after the positions of the two connecting blocks 300 at the same position are basically aligned, the two hollow conical tubes 410 are reversely sleeved on the screw 420, and the screw 420 is passed through the connecting hole 310, and then the screw 420 is fixed, and the nut 430 is rotated so that the nut 430 is close to the head of the screw 420. At this time, under the action of the two hollow conical tubes 410, the relative positions of the two sub-cabin bodies 100 are gradually fine-tuned to be completely aligned, thereby preventing steps from appearing at the connection of the sub-cabin bodies 100, avoiding problems affecting the appearance and use of the sub-cabin bodies 100.

[0047] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
