[0028] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0029] like Figures 1 to 5 As shown, a combined box-type substation in one embodiment of the utility model includes a substation box body 1 and a combined substation equipment 6. The combined substation equipment 6 is assembled and installed inside the substation box body 1. A door 5 is opened on the substation box body 1, and a box door 2 is installed at the front end of the door 5.

[0030] like Figure 4 As shown, a protective plate 3 is rotatably connected to the top of the door 5 , and the protective plate 3 can be flipped out from the inside of the door 5 to form protection above the door 5 .

[0031] Specifically, an axle rod 302 is fixed through the protective plate 3 near the top, and circular holes matching the axle rod 302 are respectively opened on both sides of the inside of the door 5. Both sides of the axle rod 302 are inserted into the inside of the circular holes on both sides and can rotate inside the circular holes, so that the protective plate 3 can be flipped inside the door 5 with the axle rod 302 as the axis.

[0032] When the protective plate 3 is flipped out from the inside of the door 5, a rain shelter can be formed above the front end of the door 5. In this way, during emergency repairs on rainy days, the rain shelter formed by the protective plate 3 can prevent rainwater from entering the substation box 1 through the door 5, thereby preventing the combined substation equipment 6 inside the door 5 from malfunctioning due to the intrusion of rainwater.

[0033] The rear end of the door 5 is fixedly connected to a limit assembly, which includes a pair of limit baffles 8, which are respectively fixedly connected to both sides of the rear end of the door 5. The door 5 can only be turned outwards but not inwards by the pair of limit baffles 8, which is convenient for resetting the limit baffles 8 after use.

[0034] Both sides of the protection plate 3 are rotatably connected with support rods 301 , and the protection plate 3 can be supported by the support rods 301 .

[0035] Specifically, a slot 801 is provided at the front end of the limit baffle 8, and one end of the support rod 301 can be inserted into the slot 801. After the protective plate 3 is turned outward, one end of the support rod 301 can be turned over and inserted into the slot 801, so that the support rod 301 can triangularly support the turned-out protective plate 3 to maintain the stable state of the protective plate 3.

[0036] In this way, when the combined power transformation equipment 6 is inspected and repaired on rainy days, both hands can be completely freed, which brings great convenience to the emergency repair work.

[0037] It is worth noting that Figure 6 As shown, the slots 801 at the front end of the limit baffle 8 can be arranged in multiple groups at equal intervals, and one end of the support rod 301 can be respectively inserted into the multiple groups of slots 801. In this way, the support rod 301 can support the protective plate 3 at multiple angles according to the use requirements, and the applicability is stronger.

[0038] Preferably, in the present embodiment, the protection plate 3 is preferably a transparent acrylic plate, which has the advantages of being light in weight and convenient for observing the operating status of the combined substation equipment 6 .

[0039] like Figures 1 to 4 As shown, the bottom end of the protective plate 3 is fixedly connected with a protective film 4. After the protective plate 3 is turned over, the protective film 4 is located at the front end of the door 5, which can achieve a more comprehensive waterproof effect.

[0040] In addition, during the emergency repair work, the workers enter the rear end of the protective film 4, and the protective film 4 can protect the workers and prevent their clothes from being wetted by rain.

[0041] It is worth noting that during the normal operation of the substation, when the rainfall is heavy in summer, rainwater may penetrate into the interior of the substation box 1 through the gaps between the box doors 2. The protective plate 3 and the protective film 4 can form a new protective barrier inside the door 5. In this way, even if the rainfall is heavy and rainwater penetrates through the gaps between the box doors 2, the protective barrier formed by the protective plate 3 and the protective film 4 can effectively prevent rainwater from invading the interior of the substation box 1, thereby ensuring the normal operation of the substation.

[0042] Preferably, in this embodiment, the protective film 4 is preferably a polyvinyl chloride film with good transparency, flexibility and weather resistance.

[0043] The bottom end of the protective film 4 is fixedly connected with a counterweight rod 401 , and the counterweight rod 401 can make the protective film 4 always perpendicular to the ground, thereby ensuring the flatness of the protective film 4 .

[0044] like Figures 2 to 5 As shown, a water retaining plate 501 is fixedly connected to the bottom end of the door 5. After emergency repairs are completed on rainy days and the protective plate 3 and the protective film 4 are reset, the water retaining plate 501 can prevent water flowing down from the protective film 4 from flowing into the interior of the substation box 1.

[0045] like Figure 2 As shown, the rear end of the protective film 4 is fixedly connected with an absorbent cloth 7. When the workers are performing emergency repair work on the combined substation equipment 6 at the rear end of the protective film 4, if there is rain on their clothes or tools, the rain can be wiped off by the absorbent cloth 7, avoiding safety hazards caused by water on the clothes or tools of the workers during the operation, and ensuring that the workers can perform emergency repair work safely.

[0046] When in use, when emergency repairs are needed on the combined substation equipment 6 inside the substation box 1 on rainy days, the box door 2 is opened, and then the protective plate 3 is turned out from the inside of the door 5, and one end of the support rod 301 is inserted into the inside of the slot 801, so that the protective plate 3 is propped up, so that the protective plate 3 and the protective film 4 can form a good waterproof protection at the front end of the door 5, and the staff can safely carry out emergency repairs at the rear end of the protective film 4;

[0047] During the repair work, the absorbent cloth 7 can be used to wipe the rainwater on the workers' clothes and tools at any time, so that the workers can work safely;

[0048] After the emergency repair is completed, one end of the support rod 301 is pulled out from the slot 801, so that the protection plate 3 loses support and automatically resets, and the box door 2 can be closed.

[0049] Compared with the prior art, the combined box-type substation of the utility model can be flexibly flipped for protection during emergency repairs on rainy days through the protective film 4, preventing rainwater from entering the substation box 1 and causing damage to the combined substation equipment 6, which greatly facilitates the emergency repair work of the staff and facilitates safe and efficient emergency repairs of the substation on rainy days.
