Description

Technical Field

[0001] The utility model relates to the field of building waterproofing, and specifically relates to a waterproof structure for a prefabricated cabin. Background Art

[0002] With the rapid development of the power industry, due to advantages such as being easy to transport, having a small floor area, low operating costs, short construction periods, and being maintenance-free, prefabricated cabins are increasingly widely used in the construction and renovation projects of substations, becoming an important part of standard distribution substations and being the replacement product of the original secondary equipment rooms.

[0003] The waterproof structure of prefabricated cabins has always been a concern for major prefabricated cabin manufacturers. The waterproof structures on the market have their own characteristics and advantages, and this invention is a new waterproof structure measure that is different from other manufacturers. Under the existing waterproof technology for the eaves of prefabricated cabins, more often, sealant is directly applied at the joints or bending parts are welded for waterproofing, but there is a certain possibility of water seepage in terms of appearance and waterproof performance. However, using square pipes for waterproofing this time can not only ensure its beauty but also greatly prevent water seepage.

[0004] To solve the above problems, therefore, we propose a waterproof structure for a prefabricated cabin. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a waterproof structure for a prefabricated cabin. To solve the above technical problems, the utility model provides the following technical solutions:

[0006] A waterproof structure for a prefabricated cabin of the utility model includes a skeleton arranged on a frame, and a roof cover is fixed on the skeleton. Square pipes are welded at the ends of the skeleton, and there is a 10 - mm gap between the square pipes and the frame. A flow - guiding plate is welded on the frame, and the cross - section of the flow - guiding plate is circular - arc - shaped. The upper side of the flow - guiding plate is located at the gap, and the lower side of the flow - guiding plate is located below the square pipes.

[0007] Preferably, a water - collecting trough is fixed on the skeleton, a filter screen plate is fixed at the upper end of the water - collecting trough, and the filter screen plate is transitionally connected to the lower eaves of the roof cover.

[0008] Preferably, a first pump wheel is fixed on the frame, a drain pipe is fixed and communicated on the side wall of the first pump wheel, and the upper end of the drain pipe is communicated with the end of the water - collecting trough.

[0009] Preferably, a second pump wheel is fixed on the frame, an air pipe is fixed and communicated on the side wall of the second pump wheel. The impeller shaft of the first pump wheel is coaxially and fixedly connected to the impeller shaft in the second pump wheel, and the upper end of the air pipe is connected to an air jet nozzle, and the air jet nozzle is fixed at the gap.

[0010] Preferably, the cross-sectional specification of the square pipe is 40mm * 40mm.

[0011] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows: By welding a square pipe on the lower side of the end of the skeleton for waterproofing, a 10mm gap is left between the square pipe and the frame. This can ensure that the water level is lower than the upper plane of the frame, effectively preventing water from flowing back, and also ensuring that the water can flow smoothly downward. The remaining gap in the middle can also prevent water from flowing back into the frame to protect electrical equipment. Moreover, this waterproof structure can also form a decorative strip in appearance to ensure the aesthetics of its appearance. And by using the water flow energy of the first pump wheel and the second pump wheel to drive the air flow velocity to increase and direct it to the bottom of the square pipe, further preventing the cross-flow of water liquid, thereby improving the waterproof effect.

[0016] The following describes the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model and are not used to limit the present utility model.

[0017] Embodiment

[0018] As Figures 1 to 2 shown, a waterproof structure for a prefabricated cabin includes a skeleton 2 provided on a frame 1, and a roof 3 is fixed on the skeleton 2. A square pipe 6 is welded to the end of the skeleton 2, and a 10mm gap is left between the square pipe 6 and the frame 1. A deflector 11 is welded to the frame 1, and the cross-section of the deflector 11 is arc-shaped. The upper side edge of the deflector 11 is located at the gap, and the lower side edge of the deflector 11 is located below the square pipe 6.

[0019] In this embodiment, a water collecting trough 4 is fixed on the framework 2, and a filter screen plate 5 is fixed at the upper end of the water collecting trough 4. The filter screen plate 5 is transitionally connected to the lower eaves of the roof cover 3. A first pump impeller 8 is fixed on the framework 1. A drain pipe 7 is fixed and communicated on the side wall of the first pump impeller 8, and the upper end of the drain pipe 7 is communicated with the end of the water collecting trough 4. A second pump impeller 9 is fixed on the framework 1, and an air pipe 10 is fixed and communicated on the side wall of the second pump impeller 9. The impeller shaft of the first pump impeller 8 is coaxially and fixedly connected with the impeller shaft in the second pump impeller 9. The upper end of the air pipe 10 is connected to a jet nozzle 12, and the jet nozzle 12 is fixed at the gap.

[0020] In this embodiment, the cross-sectional specification of the square pipe 6 is 40mm * 40mm.

[0021] Principle and advantages of the present utility model: For this prefabricated cabin waterproof structure, a square pipe 6 is welded to the lower side of the end of the framework 2 for waterproofing. There is a 10mm gap between the square pipe 6 and the framework 1, which can ensure that the water level is lower than the upper plane of the framework 1 to effectively prevent water from flowing back, and can also ensure that the water flows smoothly downward. The remaining gap in the middle can also ensure that the water does not flow back into the framework 1 to protect electrical equipment. Moreover, this waterproof structure can also form a decorative strip in appearance to ensure the aesthetics of its appearance.

[0022] Rainwater flows down on the roof cover 3 into the water collecting trough 4. The filter screen plate 5 plays a role in filtering sundries such as leaves to avoid clogging of the water collecting trough 4. After the water liquid in the water collecting trough 4 accumulates, it is discharged through the drain pipe 7. During this process, the impeller shaft in the first pump impeller 8 is driven to rotate, so that the impeller shaft in the first pump impeller 8 synchronously drives the impeller shaft in the second pump impeller 9 to rotate, enabling the second pump impeller 9 to convey air flow to the jet nozzle 12 through the air pipe 10. Under the guidance of the flow guiding plate 11, the air flow is blown towards the bottom surface of the square pipe 6, thereby further preventing the water liquid from flowing horizontally and improving the waterproof effect.

[0023] Compared with the existing waterproof structure, it can more effectively ensure preventing water from flowing back and permeating, and can also ensure the aesthetics of its appearance and the convenience of operation.

[0024] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
