Description
Technical Field
[0001] This utility model relates to the field of prefabricated cabin technology, specifically to a prefabricated cabin with a drainage structure. Background Technology
[0002] With the rapid development of the power grid, new intelligent prefabricated substations are gradually being widely promoted and applied. Compared with old-style substations, prefabricated substations have advantages in many aspects. Based on the core concept of standardized distribution, the power grid has launched outdoor intelligent substations using prefabricated modules. The adoption of prefabricated module structures has become an important measure for the construction of secondary equipment in intelligent substations.
[0003] A search revealed a utility model patent with publication number CN218466892U, which discloses a drainage structure for prefabricated cabins and the cabin itself. The structure includes a gutter, a fixing component, and a rainwater pipe. The gutter is located on the side of the prefabricated cabin. One end of the fixing component is connected to the top cover of the prefabricated cabin, and the other end is connected to the gutter. The fixing component is used to install the gutter on the prefabricated cabin. The rainwater pipe is connected to the outlet of the gutter. The gutter collects rainwater falling from the top cover of the prefabricated cabin and discharges it through the rainwater pipe. This technical solution includes a gutter and a rainwater pipe. The gutter is installed on the prefabricated cabin via the fixing component, and the outlet of the gutter is connected to the rainwater pipe. During rainy weather, rainwater falling from the top cover of the prefabricated cabin flows into the gutter, then enters the rainwater pipe from the gutter outlet, and finally discharges from the rainwater pipe. This avoids rainwater falling directly to the ground, causing water accumulation in corners and making the walls susceptible to erosion and affecting aesthetics.
[0004] While the aforementioned patent utilizes a top gutter to allow rainwater falling from the prefabricated substation roof to flow into the gutter during rainy weather, then into the rainwater pipe from the gutter outlet, and finally out through the rainwater pipe, thus avoiding the problem of rainwater falling directly to the ground and causing water accumulation in the corners, which is prone to erosion and affects aesthetics, the prefabricated substation contains a large number of heat-generating components. Without ventilation and heat dissipation channels, the heat generated by these components cannot be dissipated in time, and the resulting high temperatures accelerate the aging and damage of components and insulation parts within the substation. In severe cases, this can even lead to electrical short circuits, affecting surrounding switchgear and thus impacting the safe and stable operation of the power grid. Therefore, multiple ventilation ducts are installed and fixed on the surface of the prefabricated substation to facilitate the dissipation of heat generated by the equipment inside. However, during heavy rain, strong winds often accompany the rain, causing water droplets to come into contact with the outer wall of the prefabricated substation and enter the interior through the ventilation ducts, affecting the equipment inside.
[0005] Therefore, it is necessary to propose a prefabricated cabin with a drainage structure to solve the above problems. Summary of the Invention
[0006] The purpose of this invention is to provide a prefabricated cabin with a drainage structure. Through the cooperation of the internal parts of the heat dissipation mechanism, air can easily flow through the upper air duct to the ventilation channel to complete the heat dissipation operation of the equipment inside the prefabricated cabin. At the same time, when rainwater enters the upper air duct, the rainwater will flow through the upper air duct and finally drip into the lower air duct, and then be discharged from the interior of the prefabricated cabin through the lower air duct. This avoids rainwater remaining inside the prefabricated cabin and affecting the equipment inside. This solves the problem in the prior art that during heavy rain, which is often accompanied by strong winds, water droplets will come into contact with the outer wall of the prefabricated cabin under the influence of strong winds, and then enter the interior of the prefabricated cabin through the ventilation duct, affecting the equipment inside the prefabricated cabin.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated cabin with a drainage structure, comprising a prefabricated cabin body, a roof mechanically fixed to the top of the prefabricated cabin body, drainage mechanisms mechanically fixed to both sides of the outer wall of the prefabricated cabin body and the top of the roof, and multiple heat dissipation mechanisms opened on both sides of the outer wall of the prefabricated cabin body, which are connected to the interior of the prefabricated cabin body and located on one side of the drainage mechanism.
[0008] The drainage mechanism includes drainage tiles, and there are multiple drainage tiles. The multiple drainage tiles are mechanically fixed to both sides of the top of the roof. Drainage eaves are mechanically fixed to both sides of the roof and located below the drainage tiles. Multiple water baffles are mechanically fixed to both sides of the outer wall of the prefabricated cabin body.
[0009] The heat dissipation mechanism includes multiple upper air ducts, which are located on both sides of the outer wall of the prefabricated cabin body and are attached to the baffle plate. Lower air ducts are located on both sides of the outer wall of the prefabricated cabin body and are located at the bottom of the upper air ducts, symmetrically distributed with the upper air ducts. An air exchange pipe is provided between the upper and lower air ducts and passes through the prefabricated cabin body to the inner wall of the prefabricated cabin body. A filter screen is mechanically fixed on one side of the outer wall of the air exchange pipe where it connects with the upper and lower air ducts.
[0010] Preferably, the top of the roof is inclined at a certain slope, and multiple water-blocking plates and drainage tiles are respectively arranged on both sides of the prefabricated cabin body and on both sides of the top of the roof.
[0011] Preferably, there is a certain space between the multiple water baffles, and the water baffles are connected to the prefabricated cabin body at a certain angle. The overall structure of the drainage eaves is arc-shaped, and the bottom end is raised to both sides.
[0012] Preferably, the upper and lower air passages are both inclined at 45 degrees and opened on both sides of the outer wall of the prefabricated cabin body, and the upper and lower air passages are interconnected.
[0013] Preferably, the ventilation ducts are distributed parallel to one side of the prefabricated cabin body and extend into the interior of the prefabricated cabin body. The upper air duct, lower air duct, and ventilation duct are connected in a Y-shaped structure. The filter screen protrudes in a cone shape between the upper and lower air ducts.
[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0015] By sloping the roof at a certain angle, multiple water-blocking plates and drainage tiles are arranged on both sides of the prefabricated cabin body and the roof top, which facilitates rainwater to flow on the roof through the drainage tiles and be discharged from the roof. The water-blocking plates are installed and fixed on both sides of the prefabricated cabin body to facilitate waterproofing of the upper and lower air ducts. The drainage eaves have an overall arc shape and the bottom ends are raised to both sides, which facilitates rainwater at the top of the roof to slide off through the drainage eaves and keep it away from the outer wall of the prefabricated cabin body. This reduces the contact between rainwater and the outer wall of the prefabricated cabin body in windy and rainy weather and prevents rainwater from entering the prefabricated cabin body through the heat dissipation pipes and affecting the equipment.
[0016] By leaving space between multiple water baffles, air can flow through the baffles to the upper and lower air ducts. The upper and lower air ducts are inclined at 45 degrees on both sides of the outer wall of the prefabricated cabin body and are interconnected. The upper and lower air ducts and the ventilation pipes are connected in a Y-shaped structure. The filter screen is conical and protrudes between the upper and lower air ducts, which facilitates the normal flow of air in the upper and lower air ducts and the ventilation pipes, and completes the heat dissipation operation of the equipment inside the prefabricated cabin body. The water vapor in the air passes through the filter screen, collects on the filter screen and drips into the lower air duct, which can drain the rainwater from the inner wall of the prefabricated cabin body. This prevents rainwater from staying inside the prefabricated cabin body and affecting the equipment, and does not affect the ventilation and heat dissipation of the equipment.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0026] This utility model provides, for example Figure 1-5 The prefabricated cabin shown includes a prefabricated cabin body 1, a roof 101 mechanically fixed to the top of the prefabricated cabin body 1, drainage mechanisms 2 mechanically fixed to both sides of the outer wall of the prefabricated cabin body 1 and the top of the roof 101, and multiple heat dissipation mechanisms 3 opened on both sides of the outer wall of the prefabricated cabin body 1, which are connected to the interior of the prefabricated cabin body 1 and located on one side of the drainage mechanism 2.
[0027] The drainage mechanism 2 includes drainage tiles 201, and there are multiple drainage tiles 201. Multiple drainage tiles 201 are mechanically fixed to both sides of the top of the roof 101. Drainage eaves 202 are mechanically fixed to both sides of the roof 101 and located below the drainage tiles 201. Multiple water baffles 203 are mechanically fixed to both sides of the outer wall of the prefabricated cabin body 1.
[0028] The heat dissipation mechanism 3 includes an upper air duct 301, which has multiple upper air ducts 301. The multiple upper air ducts 301 are opened on both sides of the outer wall of the prefabricated cabin body 1 and are attached to the water baffle 203. Lower air ducts 302 are opened on both sides of the outer wall of the prefabricated cabin body 1 and are located at the bottom of the upper air ducts 301 and are symmetrically distributed with the upper air ducts 301. An air exchange pipe 303 is opened between the upper air ducts 301 and the lower air ducts 302. The air exchange pipe 303 penetrates the prefabricated cabin body 1 to the inner wall of the prefabricated cabin body 1. A filter screen 304 is mechanically fixed on one side of the outer wall of the air exchange pipe 303 where it connects with the upper air ducts 301 and the lower air ducts 302.
[0029] Through the cooperation of the internal parts of the drainage mechanism 2, rainwater at the top of the roof 101 can slide down through the drainage eaves 202 and stay away from the outer wall of the prefabricated cabin body 1, reducing the contact between rainwater and the outer wall of the prefabricated cabin body 1 under the influence of strong winds. Through the cooperation of the internal parts of the heat dissipation mechanism 3, when rainwater enters the upper air duct 301, the rainwater will flow in the upper air duct 301 and finally drip into the lower air duct 302, and be discharged from the interior of the prefabricated cabin body 1 from the lower air duct 302, thus avoiding rainwater remaining in the prefabricated cabin body 1 and affecting the internal equipment of the prefabricated cabin body 1.
[0030] Refer to the instruction manual appendix Figure 1-5 The top of the roof 101 is inclined at a certain slope, and multiple water baffles 203 and drainage tiles 201 are arranged and distributed on both sides of the prefabricated cabin body 1 and the top of the roof 101. By inclining the top of the roof 101 at a certain slope and arranging multiple water baffles 203 and drainage tiles 201 on both sides of the prefabricated cabin body 1 and the top of the roof 101, rainwater can flow on the roof 101 through the drainage tiles 201 and be discharged from the roof 101.
[0031] Refer to the instruction manual appendix Figure 1-5 There is a certain space between the multiple water baffles 203, and the water baffles 203 are connected to the prefabricated cabin body 1 at a certain angle. The overall structure of the drainage eaves 202 is arc-shaped, and the bottom end is raised to both sides. The overall structure of the drainage eaves 202 is arc-shaped, and the bottom end is raised to both sides, so that the rainwater at the top of the roof 101 can slide down through the drainage eaves 202 and stay away from the outer wall of the prefabricated cabin body 1.
[0032] Refer to the instruction manual appendix Figure 1-5 The upper air duct 301 and the lower air duct 302 are both inclined at 45 degrees and are located on both sides of the outer wall of the prefabricated cabin body 1. The upper air duct 301 and the lower air duct 302 are connected to each other. Because the upper air duct 301 and the lower air duct 302 are both inclined at 45 degrees and are connected to each other, rainwater can enter the upper air duct 301 and then roll into the lower air duct 302 and finally be discharged through the lower air duct 302, so that rainwater cannot stay inside the prefabricated cabin body 1.
[0033] Refer to the instruction manual appendix Figure 1-5The ventilation duct 303 is distributed parallel to one side of the prefabricated cabin body 1 and extends into the interior of the prefabricated cabin body 1. The upper air duct 301 is connected to the lower air duct 302 and the ventilation duct 303 in a Y-shaped structure. The filter screen 304 protrudes in a cone shape between the upper air duct 301 and the lower air duct 302. The Y-shaped structure of the upper air duct 301, lower air duct 302 and ventilation duct 303 and the conical protrusion of the filter screen 304 between the upper air duct 301 and the lower air duct 302 facilitates the normal flow of air in the upper air duct 301, lower air duct 302 and ventilation duct 303, completing the heat dissipation operation of the equipment inside the prefabricated cabin body 1. The water vapor in the air will pass through the filter screen 304 and accumulate on the filter screen 304 and drip down to the lower air duct 302.
[0034] The working principle of this practical application is as follows:
[0035] Refer to the instruction manual appendix Figure 1-5 By tilting the top of the roof 101 at a certain angle, multiple baffles 203 and drainage tiles 201 are arranged and distributed on both sides of the prefabricated cabin body 1 and both sides of the top of the roof 101, so that rainwater can flow on the roof 101 through the drainage tiles 201 and be discharged from the roof 101. The baffles 203 are installed and fixed on both sides of the prefabricated cabin body 1 to facilitate waterproofing of the upper air duct 301 and the lower air duct 302. The drainage eaves 202 have an arc-shaped overall structure and the bottom end is raised to both sides, so that rainwater at the top of the roof 101 can slide off through the drainage eaves 202 and stay away from the outer wall of the prefabricated cabin body 1. This reduces the contact between rainwater and the outer wall of the prefabricated cabin body 1 in windy and rainy weather and prevents rainwater from entering the prefabricated cabin body 1 through the heat dissipation pipes and affecting the equipment.
[0036] Refer to the instruction manual appendix Figure 1-5 A certain space is left between the multiple water baffles 203 to facilitate airflow through the water baffles 203 to the upper air duct 301 and lower air duct 302. The upper air duct 301 and lower air duct 302 are both inclined at 45 degrees on both sides of the outer wall of the prefabricated cabin body 1 and are interconnected. This allows rainwater to enter the upper air duct 301 under the influence of strong winds, roll into the lower air duct 302, and finally be discharged through the lower air duct 302, preventing rainwater from remaining inside the prefabricated cabin body 1. 2. The ventilation duct 303 is connected in a Y-shape, and the filter screen 304 is conical and protrudes between the upper air duct 301 and the lower air duct 302, which facilitates the normal flow of air in the upper air duct 301, the lower air duct 302 and the ventilation duct 303, and completes the heat dissipation operation of the equipment inside the prefabricated cabin body 1. The water vapor in the air will pass through the filter screen 304 and collect on the filter screen 304 and drip down to the lower air duct 302, which can drain the rainwater on the inner wall of the prefabricated cabin body 1, so that the rainwater cannot stay inside the prefabricated cabin body 1 and affect the equipment, and will not affect the ventilation and heat dissipation of the equipment.
[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
