DETAILED DESCRIPTION

[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] Embodiment 1, as Figure 1 to Figure 7 As shown, this embodiment aims to provide a mobile emergency power supply prefabricated cabin that is easy to use and small in size. To this end, this embodiment provides a traction frame 1 and a cabin 2 arranged on the traction frame 1. Emergency power supply equipment is arranged in the cabin 2. The emergency power supply equipment mentioned in this embodiment refers to power generation equipment, high-voltage switch equipment, data transmission unit DTU, distribution switch monitoring terminal FTU, remote measurement and control unit RTU, cable winding machine, portable engine, uninterruptible power supply UPS and other equipment required for emergency power supply. A sealing door 21 for opening the cabin 2 is arranged on the side wall of one side of the cabin 2. Like the existing prefabricated cabin, multiple sealing doors 21 are also arranged for the maintenance or use of different equipment.

[0026] Considering that the entire emergency power supply prefabricated cabin contains the most power supply, in order to save the space occupied by the hydraulic pump station, in this embodiment, four evenly distributed folding mechanical jacks 3 are arranged on the traction frame 1. The folding mechanical jack 3 includes an articulated frame 31 and a screw 32 for driving the articulated frame 31. The articulated frame 31 is arranged in a rhombus shape as a whole, and a screw 32 is arranged in the middle. The articulated frame 31 is driven to deform through the transmission of the screw 32 to form a support. The folding mechanical jack 3 is an existing mature product, so it is not described in detail in this embodiment. In order to realize the automatic control rotation of the screw 32, a synchronous wheel 33 is installed at one end of the screw 32 away from the articulated frame 31. In this embodiment, in order to ensure the stability of the rotation of the screw 32, a bearing seat 34 is arranged on the frame to realize the stable rotation of the screw 32. Of course, a bearing is arranged in the bearing seat 34. A driving motor 4 is arranged in the middle of the traction frame 1. The driving motor 4 can be a servo motor, which is small in size and does not occupy the space of the cabin 2 at all. In this embodiment, the power end of the driving motor 4 is arranged vertically downward, and a bevel gear 41 is mounted on the power end of the driving motor 4. Auxiliary bevel gears 42 matching the bevel gear 41 are arranged on both sides of the bevel gear 41. The purpose of arranging the auxiliary bevel gears 42 on both sides is to enable one driving motor 4 to control two folding mechanical jacks 3 at the same end of the traction frame 1. In this way, a total of two driving motors 4 are arranged on the traction frame. A rotating shaft is mounted inside the auxiliary bevel gear 42. In the present embodiment, in order to ensure the rotation of the rotating shaft, a protective cover 45 is further provided at the bottom of the pulling frame. The protective cover 45 is provided in a rectangular parallelepiped shape, and covers the bevel gear 41 and the auxiliary bevel gear 42 therein. At the same time, a bearing is provided at the place where the rotating shaft passes through to ensure the rotation of the rotating shaft. In the present embodiment, the protective cover 45 has two functions: 1. It plays a role in protecting the bevel gear 41 and the auxiliary bevel gear 42. At the same time, when in use, the transmission between the bevel gear 41 and the auxiliary bevel gear 42 needs to be lubricated, and the protective cover 45 can also play the role of a lubricating oil container; another purpose is to maintain the rotating shaft, which is equivalent to the use of a rotating shaft fixing device.

[0027] Considering that the ground where the prefabricated cabin is placed may be uneven, and if the drive motor 4 is used, only two folding mechanical jacks 3 can be lifted and lowered at the same time, in order to achieve individual control while reducing the number of drive motors 4 used, an electromagnetic clutch 43 is provided at the end of the shaft away from the auxiliary bevel gear 42, and a synchronous belt 44 is provided between the clutch end of the electromagnetic clutch 43 and the synchronous wheel 33. The electromagnetic clutch 43 controls the engagement and separation of the clutch by turning on and off the power of the coil. In this way, when the lower position of the folding mechanical jack 3 on one side is reached, the electromagnetic clutch 43 is disconnected, so that the shaft rotates dry and cannot control the screw 32, thereby achieving individual control of the four folding mechanical jacks 3.

[0028] Through the above-mentioned arrangement, the structural design of the foldable mechanical jack 3 is controlled by the driving motor 4, which realizes the replacement of the hydraulic support legs and the hydraulic pump station, thereby reducing the space occupied by the hydraulic pump station in the cabin 2. At the same time, the reduction in space is also conducive to the entire prefabricated cabin meeting the C-class driving standards, providing a guarantee for the convenient use of the entire prefabricated cabin. At the same time, even without reducing the space of the cabin 2, more emergency power supply equipment can be installed to meet diverse needs.

[0029] Considering that the incoming wire 5 and the discharge wire 8 required by the existing emergency power supply equipment are placed in the cabin 2, the incoming wire 5 is mainly connected to the power grid to quickly cut off the faulty part from the power grid when the power equipment or line fails, while the discharge wire 8 is used for discharge. When the incoming wire 5 and the discharge wire 8 are used, it is necessary to open the sealing door 21, then take the wire head, and then quickly release the wire. The whole operation steps are cumbersome and occupy a certain space for the convenience of the staff to take. Therefore, in order to simplify the operation steps and reduce the space occupancy, in this embodiment, a wire release groove 22 is set on the side wall of the cabin 2 away from the sealing door 21. The wire release groove 22 occupies three sides of the entire prefabricated cabin, and a hole is punched on the side wall of one side of the cabin 2 to allow the incoming wire 5 to enter the wire release groove 22.

[0030] In order to prevent the incoming wire 5 from falling off from the wire release groove 22, a drag chain 51 is arranged in the wire release groove 22, and the incoming wire 5 is sleeved in the drag chain 51. At the same time, a limiting plate 23 for preventing the drag chain 51 is arranged on the top of the wire release groove 22, and a through hole for the incoming wire 5 to extend out is opened in the middle of the limiting plate 23. The structural arrangement of the limiting plate 23 and the through hole can be seen as two upper and lower plates with a certain distance therebetween. The use of the limiting plate 23 is mainly to prevent the drag chain 51 from falling off from the placement groove. The reason why the incoming line 5 is arranged in the drag chain 51 is mainly because the width of the through hole should meet the requirements of taking out the incoming line 5. For this reason, the setting of the drag chain 51 prevents the incoming line 5 from falling off. At the same time, the drag chain 51 is also conducive to keeping the incoming line 5. The length of the drag chain 51 is based on nearly covering the entire wire placement groove 22. In actual use, the incoming line 5 with a fixed outlet may need to pull out a lot of wires to ensure accurate connection with the power supply equipment due to the position of the entire prefabricated cabin. By utilizing the placement groove and the setting of the drag chain 51, the outlet of the incoming line 5 can be adjusted to the position closest to the power supply equipment, thereby reducing the pulling distance of the incoming line 5 and avoiding unnecessary risks caused by too long lines. At the same time, the end of the incoming line 5 is set on the cabin body 2. In this way, the space reserved for manual entry into the cabin to take the line can be saved, thereby further reducing the space of the entire prefabricated cabin, providing convenience for its convenient use.

[0031] In order to better protect the incoming wire 5, an incoming wire tube 52 is provided in the drag chain 51. The incoming wire 5 is arranged in the incoming wire tube 52 and extends out of the incoming wire tube 52. In this embodiment, the incoming wire tube 52 is a foldable tube for easy use.

[0032] In this way, through the above-mentioned arrangement, after the entire prefabricated cabin is placed, the incoming wire 5 is pulled, and the drag chain 51 is in a bent state. When the optimal position is reached, the incoming wire 5 is pulled and connected to the power supply equipment. Such an arrangement not only reduces a certain amount of space, but also facilitates parking. There is no need to consider the position. The vehicle can be parked as soon as it enters the site, which saves the time for parking and adjusting the position and makes the operation faster.

[0033] Similarly, in order to reduce the space at the end of the discharge wire 8, a wire outlet mechanism is provided on the sealing door 21. Since there are multiple sealing doors 21, in this embodiment, the wire outlet mechanism is arranged at the position closest to the wire rack of the discharge wire 8. In order to achieve rapid access to the discharge wire 8, the wire outlet mechanism provided in this embodiment includes a fixing frame 6 arranged on the sealing door 21 and a wire outlet box 7 arranged in the fixing frame 6. In this embodiment, the wire outlet box 7 is arranged in a rectangular box, and the fixing frame 6 is mainly used to place the wire outlet box 7. A wire outlet hole 24 is provided on the sealing door 21, and a slide is provided at the bottom of the fixing frame 6, so that the wire outlet box 7 is slidably arranged in the fixing frame 6. The wire outlet box 7 A wire hole 24 can be extended. A wire entry hole is provided at one end of the wire box 7 away from the sealing door 21. The wire entry hole is mainly used for the discharge wire 8 to enter the wire box 7. Rollers 71 are provided on the upper and lower parts of the wire box 7. A wire entry slot 711 is provided on the roller 71. The roller 71 is rotatably provided in the wire box 7. The roller 71 has two purposes: one is to maintain the discharge wire 8 and stabilize the position of the end of the discharge wire 8. The other purpose is to facilitate the recovery of the discharge wire 8. A protruding hole 72 is provided at one end of the wire box 7 close to the sealing door 21. The discharge wire 8 protrudes out of the wire box 7 through the wire entry hole, the wire entry slot 711 and the protruding hole 72.

[0034] Through the above arrangement, when using the discharge wire 8, the outlet box 7 is partially pulled out, and then the discharge wire 8 is grabbed and quickly pulled out. This arrangement also saves the need for manual entry into the cabin 2, thereby achieving the purpose of saving space.

[0035] In order to maintain the position of the outlet box 7, a spring lock 9 for fixing the outlet box 7 is also provided on the side wall of the outlet hole 24. The provision of the spring lock 9 facilitates the taking and placing of the outlet box 7.

[0036] In order to close the outlet hole 24 and protect the outlet box 7, a sealing cover 25 for closing the outlet hole 24 is also provided on the sealing door 21. The sealing cover 25 can be flipped and fixed on the sealing door 21. The sealing cover 25 also adopts a lock buckle to achieve rapid opening and closing.

[0037] Through the above-mentioned arrangement, the volume of the prefabricated cabin can be reduced as much as possible while being convenient to use, which not only saves costs but also makes its application scope more extensive.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
