Description

Technical Field

[0002] A box-type substation, also known as a prefabricated substation or prefabricated substation, is a factory-prefabricated indoor and outdoor compact distribution equipment that integrates high-voltage switchgear, distribution transformers and low-voltage distribution devices. Box-type substations are also used in systems that use solar power generation, namely photovoltaic box-type substations.

The photovoltaic panels are arranged on the top of the substation box to receive light according to actual installation needs, and the photovoltaic panels are electrically connected to the internal components of the substation box through power transmission components. The photovoltaic panels then convert solar energy into electrical energy and centrally transmit it to the box-type substation, where it is then converted and distributed.

[0004] The shortcomings of the existing photovoltaic box-type substation are that the existing photovoltaic box-type substation is used outdoors for a long time, and the photovoltaic panels equipped therein may inevitably be damaged due to some external environmental weather factors during long-term use. Once damaged, they need to be replaced in time. However, when the existing photovoltaic panels are damaged after installation, maintenance personnel need to rush to the substation site first. In order to reduce the time wasted on electricity, the damaged photovoltaic panels need to be replaced.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figure 1-Figure 9 As shown, a box-type substation using solar power generation includes a substation box 1 and a main photovoltaic panel 4. A substation component is installed inside the substation box 1. The direct current generated by the main photovoltaic panel 4 is first input into the substation box 1, and then converted into alternating current by the inverter in the substation box 1, and finally output and distributed to the power grid; a plurality of groups of mounting pallets are horizontally distributed on the top of the substation box 1, each group of mounting pallets corresponds to a main photovoltaic panel 4, and each group of mounting pallets includes two pallet bodies 2, which are symmetrically fixedly connected to the top of the substation box 1, and there is a gap between the two pallet bodies 2. A certain distance is maintained, and a certain distance is reserved between the support plate body 2 and the top of the substation box body 1. The substation also includes a spare storage box 11, a first sliding connection assembly, a second sliding connection assembly, and a power connection lifting assembly; the spare storage box 11 is fixedly connected to the top of the substation box body 1, and is located below the space between the two support plate bodies 2. Both ends of the spare storage box 11 are open, that is, it is horizontally through. A spare photovoltaic panel 13 is arranged inside the spare storage box 11, and the spare photovoltaic panel 13 is equipped with a spare power connection socket 17, and the spare power connection socket 17 is electrically connected to the power transmission element in the spare photovoltaic panel 13;

[0037] The first sliding connection assembly is arranged on the support plate body 2, a first connection slide plate 27 is fixedly connected to the bottom of the main photovoltaic panel 4, and the first connection slide plate 27 is slidably connected to the support plate body 2 through the first sliding connection assembly, both ends of the first connection slide plate 27 are fixedly connected to the main power socket 6 electrically connected to the main photovoltaic panel 4, the second sliding connection assembly is arranged in the spare storage box 11, and the spare photovoltaic panel 13 is slidably connected to the spare storage box 11 through the second sliding connection assembly; a driving assembly is connected between the two support plate bodies 2, the first sliding connection assembly and the second sliding connection assembly are both connected to the driving assembly, and the first sliding connection assembly and the second sliding connection assembly move in opposite directions;

[0038] The power connection lifting assembly is arranged on the side wall of the transformer substation box 1, and the power connection lifting assembly is electrically connected to the transformer substation assembly in the transformer substation box 1, and the main power connection socket 6 and the spare power connection socket 17 are both matched with the power connection lifting assembly. In the initial state, the main power connection socket 6 is docked with the power connection lifting assembly. When the main photovoltaic panel 4 is damaged and cannot continue to output electric energy, the first sliding connection assembly and the second sliding connection assembly are driven by the driving assembly. The first sliding connection assembly drives the main photovoltaic panel 4 to move horizontally, and at this time, the main power connection socket 6 is convenient for the power connection lifting assembly to separate. Since the first sliding connection assembly and the second sliding connection assembly have opposite movement directions, the second sliding connection assembly drives the spare photovoltaic panel 13 to slide out of the spare storage box 11, and the spare photovoltaic panel 13 relies on the spare power connection socket 17 to dock with the power connection lifting assembly to realize photovoltaic panel switching.

[0039] In some specific embodiments, such as Figure 2 As shown, the first sliding connection assembly includes a first rack 7, and first strip-shaped grooves 20 are transversely opened on opposite sides of the two support plate bodies 2. Two first racks 7 are provided, and are horizontally slidably connected to the corresponding first strip-shaped grooves 20, and one end of the first rack 7 is fixedly connected to the first connecting slide plate 27. In order to ensure that the first rack 7 can fully slide transversely for a certain distance, the end of the first rack 7 close to the main photovoltaic panel 4 is slidably connected to the first strip-shaped groove 20 through a slider, and the first rack 7 is cooperatively connected to the driving assembly.

[0040] In some specific embodiments, such as Figure 4As shown, the second sliding connection assembly includes a second rack 9 and a second connecting slide plate 12. Second strip slide grooves 19 are horizontally opened on the inner walls of both sides of the spare storage box 11. The length of the second strip slide groove 19 is shorter than the length of the first strip slide groove 20. The second connecting slide plate 12 is arranged in the spare storage box 11 and is slidably connected to the second strip slide groove 19. Since the length of the second strip slide groove 19 is shorter than the length of the first strip slide groove 20, the sliding stroke of the second connecting slide plate 12 is shorter than the sliding stroke of the first connecting slide plate 27. Two spare power sockets 17 are provided and fixedly connected to one side of the second connecting slide plate 12 and distributed in pairs. One end of the spare photovoltaic panel 13 is connected to the second through a rebound hinge. The connecting slide 12 is movably connected. When the spare photovoltaic panel 13 is stored in the spare storage box 11, the rebound hinge has a rebound force. When the second connecting slide 12 slides from one end to the other end along the second strip slide 19, the spare photovoltaic panel 13 is separated from the spare storage box 11, and the limit is released, so that the spare photovoltaic panel 13 is rotated and tilted by relying on the rebound force of the rebound hinge. Since the spare photovoltaic panel 13 needs to rotate and the spare power socket 17 is fixed on the second connecting slide 12, the spare power socket 17 and the spare photovoltaic panel 13 are electrically connected through a flexible cable. Two second racks 9 are provided and are slidably connected to the other side of the second connecting slide 12; the second rack 9 is connected with the driving assembly.

[0041] Among them, two sliding slots 15 are opened in pairs on the other side of the second connecting slide plate 12, one end of the two second racks 9 slides and inserts into the corresponding sliding slots 15 respectively, and a compressible connecting spring 16 is connected between the second racks 9 and the corresponding sliding slots 15.

[0042] In some specific embodiments, in order to enable the first sliding connection component and the second sliding connection component to move simultaneously and in opposite directions, as Fig. 9 As shown, the driving assembly includes a driving motor 10 and a linkage gear 8. The driving motor 10 is fixedly connected to one of the support plates 2. The main shaft end of the driving motor 10 is coaxially connected to the transverse axis 26. The linkage gear 8 is coaxially connected to the transverse axis 26. There are two linkage gears 8. The first rack 7 and the second rack 9 are respectively meshed on the upper and lower sides of the same linkage gear 8.

[0043] When one of the main photovoltaic panels 4 is damaged and cannot continue to transmit electricity, the background monitoring personnel will remotely control the operation of the drive motor 10 when they detect the problem, or install a PLC controller and a power detector on the circuit of the main photovoltaic panel 4. When the power detector cannot detect that the main photovoltaic panel 4 has current output or the main photovoltaic panel 4 has various power indexes that are abnormal, it will feedback the signal to the PLC controller, and the PLC controller will control the drive motor 10 to run automatically. The drive motor 10 will drive the linkage gear 8 to rotate through the horizontal axis 26, and the linkage gear 8 will drive the first rack 7 and the second rack 9 to start sliding horizontally at the same time, and the sliding directions of the two are opposite. The first rack 7 moves away from the standby photovoltaic panel along the first strip slide 20. When the second connecting slide plate 12 slides to the end position of the second strip slide groove 19 and cannot move forward, the spare photovoltaic panel 13 is completely exposed, so that it is convenient to rotate and tilt by relying on the rebound force of the rebound hinge. Since the sliding stroke of the second connecting slide plate 12 is shorter than the sliding stroke of the first connecting slide plate 27, the first connecting slide plate 27 has not stopped at this time, and the linkage gear 8 continues to push the second rack 9 to move horizontally and insert it into the corresponding sliding slot 15, thereby avoiding hindering the linkage gear 8 from driving the first rack 7 to continue to move horizontally.

[0044] In some specific implementation schemes, in order to ensure that the main photovoltaic panel 4 and the backup photovoltaic panel 13 are in alternating positions, the main power socket 6 and the backup power socket 17 can be alternately connected to the power lifting assembly, such as Figure 3 As shown, the power connection lifting assembly includes a connecting rail 3 and a power connection plug 5. The connecting rail 3 is vertically fixedly connected to one side of the transformer substation box 1 and is distributed in pairs. A connecting slider 28 is slidably connected in the connecting rail 3. The connecting slider 28 is laterally limited in the connecting rail 3 and can only move longitudinally but cannot be separated laterally. A supporting spring 14 is connected between the connecting slider 28 and the bottom of the connecting rail 3. The power connection plug 5 is fixedly connected to the connecting slider 28. The main power connection socket 6 and the spare power connection socket 17 are both matched with the power connection plug 5. The power connection plug 5 is electrically connected to the transformer substation assembly in the transformer substation box 1 through a certain length of flexible cable.

[0045] When the main photovoltaic panel 4 is in normal use, the power plug 5 slides to the top along the connecting guide rail 3 by relying on the connecting slider 28. At this time, the power plug 5 is aligned with the main power socket 6, and the two are plugged together. At this time, the support spring 14 is stretched to generate a rebound force. When the main photovoltaic panel 4 has a problem and moves away laterally, the main power socket 6 is separated from the power plug 5, and then the power plug 5 relies on the rebound force of the support spring 14 to slide down quickly, that is, slide to the Figure 3In the position shown, the power plug 5 is laterally aligned with the spare power socket 17, so that when the second connecting slide 12 slides to the end position of the second strip slide groove 19 and stops, the spare power socket 17 is just connected with the power plug 5, thereby realizing automatic switching of power connection.

[0046] In some specific implementation schemes, when the spare photovoltaic panel 13 is rotated and tilted, in order to fix its position and stably receive light for operation, the spare photovoltaic panel 13 needs to be limited and fixed. In order to achieve automatic snap-in, a linkage snap-in mechanism connected to the first rack 7 is installed on the support body 2, and the linkage snap-in mechanism cooperates with the spare photovoltaic panel 13.

[0047] In some specific embodiments, such as Figure 7 As shown, the linkage buckle mechanism includes a guide sleeve 22, a bolt 24 and a sleeve 18. The guide sleeve 22 is fixedly connected to the support plate body 2, the bolt 24 is slidably inserted into the guide sleeve 22, and a stretchable return spring 25 is connected between the bolt 24 and the guide sleeve 22. The sleeve 18 is fixedly connected to the edge position of the spare photovoltaic panel 13, and the sleeve 18 cooperates with one end of the bolt 24, and a traction assembly is connected between the other end of the bolt 24 and the first rack 7.

[0048] Among them, the traction assembly includes a traction wire 21 and a guide tube 23. The traction wire 21 is connected between the bolt 24 and the first rack 7. When the main photovoltaic panel 4 is in the use position, the traction wire 21 is in a relaxed state, the guide tube 23 is fixedly connected to the support plate body 2, and the traction wire 21 passes through the guide tube 23, and the guide tube 23 plays a guiding role.

[0049] When the linkage gear 8 drives the first rack 7 and the second rack 9 to move horizontally, the first rack 7 drives the traction wire 21. During this process, the traction wire 21 is still in a relaxed state. When the second rack 9 drives the second connecting slide plate 12 to slide to the end position of the second strip slide groove 19 and stops, the spare photovoltaic panel 13 is completely exposed and rotated and tilted. At this time, the sleeve 18 on the spare photovoltaic panel 13 is just aligned with the bolt 24, and the traction wire 21 is just tightened. Since the second rack 9 has not yet been inserted into the corresponding sliding slot 15, the linkage gear 8 continues to drive the first rack 7 and the second rack 9 to move horizontally. The first rack 7 pulls the bolt 24 to slide relative to the guide sleeve 22 through the tightened traction wire 21, and stretches the reset spring 25, so that the bolt 24 slides into the sleeve 18 to fix the spare photovoltaic panel 13, and the drive motor 10 can be self-locking when it stops, thus ensuring that the position of the spare photovoltaic panel 13 is fixed, which is convenient for use.

[0050] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0051] When the main photovoltaic panel 4 is in normal use, the power plug 5 slides to the top along the connecting guide rail 3 by relying on the connecting slider 28. At this time, the power plug 5 is aligned with the main power socket 6, and the two are plugged together. At this time, the support spring 14 is stretched to generate a rebound force.

[0052] When one of the main photovoltaic panels 4 is damaged and cannot continue to transmit electricity, the drive motor 10 is running. The drive motor 10 drives the linkage gear 8 to rotate through the horizontal axis 26, and the linkage gear 8 drives the first rack 7 and the second rack 9 to start sliding horizontally at the same time, and the sliding directions of the two are opposite. The first rack 7 slides along the first strip-shaped slide groove 20 in the direction away from the spare photovoltaic panel 13. During this process, the first rack 7 drives the main photovoltaic panel 4 to move horizontally to one side of the substation box 1, and during this process, the main power socket 6 is separated from the power plug 5, and then the power plug 5 relies on the rebound force of the support spring 14 to slide down quickly. After sliding down, the power plug 5 is horizontally aligned with the spare power socket 17.

[0053] The second rack 9 pushes the second connecting slide plate 12 to slide laterally in the opposite direction. During this process, the second connecting slide plate 12 drives the spare photovoltaic panel 13 to gradually move laterally out of the spare storage box 11 and expose it. When the second connecting slide plate 12 slides to the end position of the second strip slide groove 19 and cannot move forward, the spare photovoltaic panel 13 is completely exposed, so that it is easy to rotate and tilt up by relying on the rebound force of the rebound hinge, and at this time, the spare power socket 17 on the second connecting slide plate 12 is just connected to the power plug 5, thereby realizing automatic switching of power connection.

[0054] Since the sliding stroke of the second connecting slide 12 is shorter than the sliding stroke of the first connecting slide 27, the first connecting slide 27 has not stopped at this time, and the linkage gear 8 continues to push the second rack 9 to move horizontally and insert it into the corresponding sliding slot 15, thus avoiding hindering the linkage gear 8 from driving the first rack 7 to continue to move horizontally;

[0055] After the spare photovoltaic panel 13 is rotated and tilted, the sleeve 18 on the spare photovoltaic panel 13 is aligned with the bolt 24, and at this time the first rack 7 just tightens the traction wire 21, and the linkage gear 8 continues to drive the first rack 7 and the second rack 9 to move horizontally, and the first rack 7 pulls the bolt 24 to slide relative to the guide sleeve 22 through the tightened traction wire 21, and stretches the reset spring 25, so that the bolt 24 slides into the sleeve 18 to fix the spare photovoltaic panel 13, and the drive motor 10 can self-lock when it stops, so that the position of the spare photovoltaic panel 13 can be fixed, which is convenient for use, and the second rack 9 slides into the corresponding sliding slot 15.

[0056] Several embodiments of the present invention are described in detail above, but the embodiments of the present invention are not limited thereto and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
