Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] A modular prefabricated cabin substation includes a cabin body 1, a plurality of maintenance doors 101 are arranged on the front of the cabin body 1, an annular opening 2 is arranged on the top of the cabin body 1, a maintenance passage 3 is fixedly connected to the top of the cabin body 1 and above the annular opening 2, the maintenance passage 3 and the annular opening 2 are used to assist maintenance personnel to enter the interior of the cabin body 1 from the top, and a rainproof cover 4 is arranged on the top of the maintenance passage 3.

[0026] A fixed tube 5 is fixedly connected inside the annular opening 2, a separating ring 6 is fixedly connected inside the fixed tube 5, a tension spring 7 is fixedly connected to the top of the separating ring 6 and located inside the fixed tube 5, a telescopic column 8 is fixedly connected to the top of the tension spring 7, the top of the telescopic column 8 is fixedly installed with the rain cover 4, and is used to drive the rain cover 4 to move up and down, and a movable pull rope 9 is provided at the bottom of the telescopic column 8, and the bottom of the pull rope 9 passes through the tension spring 7 and the separating ring 6 in sequence and extends to the outside of the separating ring 6.

[0027] like Figure 1 The cabin 1 with multiple maintenance doors 101 is the existing technology, and fans and other ventilation mechanisms, as well as a fire warning system are also provided inside to ensure the safety inside the modular prefabricated cabin substation. The maintenance passage 3 is above the annular opening 2 to prevent rainwater deposited on the top of the cabin 1 from entering the cabin 1. At the same time, maintenance personnel can enter the maintenance passage 3 through the maintenance passage 3 and the annular opening 2.

[0028] Guide rods 10 are fixedly connected in the cabin 1 and on both sides of the annular opening 2 , a sliding plate 11 is slidably connected to the guide rods 10 , and one end of the pull rope 9 away from the telescopic column 8 is fixedly connected to the sliding plate 11 .

[0029] like Figure 3 Each sliding plate 11 has two parallel guide rods 10 passing through the sliding plate 11, so that the sliding plate 11 can only move horizontally.

[0030] A bidirectional electric telescopic rod 12 is fixedly installed in the cabin 1 , and two ends of the bidirectional electric telescopic rod 12 are fixedly connected to two sliding plates 11 respectively.

[0031] like Figure 3 The two ends of the bidirectional electric telescopic rod 12 are respectively fixed to the two sliding plates 11, so that the two sliding plates 11 can move away from or towards each other at the same time.

[0032] The rainproof cover 4 is fixedly connected with an inclined guide ring 13 around its periphery, and a blocking ring 14 is fixedly connected with its bottom. The blocking ring 14 is sleeved on the outer surface of the maintenance channel 3 .

[0033] like Figure 4 and Figure 5 By arranging an inclined guide ring 13 around the rain cover 4, rainwater falling on the top of the rain cover 4 can be diverted, making it easier for rainwater to flow around the rain cover 4, thereby preventing rainwater from entering the maintenance channel 3. At the same time, the blocking ring 14 can be used to prevent rainwater from flowing back along the bottom of the inclined guide ring 13 and entering the maintenance channel 3.

[0034] A cavity 801 is formed at the bottom of the telescopic column 8 , and the top of the tension spring 7 and one end of the pull rope 9 are fixedly connected to the top of the inner wall of the cavity 801 .

[0035] like Figure 4 The cavity 801 opened at the bottom of the telescopic column 8 can provide space for the arrangement of the tension spring 7, thereby improving space utilization.

[0036] The top of the rain cover 4 is fixedly connected with a raised sleeve 15, and a fixing bolt 16 is arranged in the raised sleeve 15. The bottom of the fixing bolt 16 passes through the raised sleeve 15 and the rain cover 4 and extends to the bottom of the rain cover 4. The fixing bolt 16 is threadedly connected to the top of the telescopic column 8, and the outer surface of the raised sleeve 15 is provided with a waterproof sleeve 17.

[0037] like Figure 5 By using the waterproof cover 17 to cover the outside of the raised cover 15, rainwater can be prevented from contacting the fixing bolts 16 in the raised cover 15, and the fixing bolts 16 can be prevented from rusting. There are screw holes on the top of the telescopic column 8 to achieve threaded connection with the fixing bolts 16. Before removing the fixing bolts 16, the waterproof cover 17 can be removed. After the fixing bolts 16 are installed, the waterproof cover 17 can be covered over the raised cover 15.

[0038] The working principle of the modular prefabricated cabin substation provided by the utility model is as follows:

[0039] When the interior of the cabin 1 needs to be ventilated, the bidirectional electric telescopic rod 12 can be controlled to retract, and the bidirectional electric telescopic rod 12 drives the two sliding plates 11 to move toward each other. At this time, the tension spring 7 extends to push the telescopic column 8 upward, and the telescopic column 8 drives the rain cover 4 to move upward, forming a cavity connected to the outside between the rain cover 4 and the maintenance passage 3, thereby enhancing the ventilation capacity of the interior of the cabin 1;

[0040] When there is no need to ventilate the interior of the cabin 1, the bidirectional electric telescopic rod 12 can be controlled to extend, and the extension of the bidirectional electric telescopic rod 12 drives the two sliding plates 11 to move away from each other, and the sliding plates 11 drive the pull rope 9 to move together. At this time, the pull rope 9 pulls the telescopic column 8 downward, and the telescopic column 8 drives the rain cover 4 to move downward, so that the rain cover 4 is attached to the top of the maintenance channel 3 again, providing rain protection for the interior of the cabin 1;

[0041] When it is necessary to enter the interior of the cabin 1 from the maintenance passage 3 on the top of the cabin 1, the fixing bolts 16 can be removed, and the rain cover 4 can be manually moved up and removed, and the maintenance personnel can enter the interior of the cabin 1 through the maintenance passage 3.

[0042] Compared with the related art, the modular prefabricated cabin substation provided by the utility model has the following beneficial effects:

[0043] By setting up a maintenance passage 3 on the top of the cabin 1, it is convenient for maintenance personnel to go from the top of the cabin 1 to the inside of the cabin 1. By utilizing the telescopic effect of the bidirectional electric telescopic rod 12 and the tension of the tension spring 7, when the cabin 1 needs to be ventilated, the rain cover 4 can be moved up to enhance the ventilation capacity of the cabin 1 from the maintenance passage 3 on the top of the cabin 1. When ventilation is not needed, the rain cover 4 can be lowered to provide better protection for the top of the cabin 1.

[0044] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
