It integrates a variety of electrical equipment and is equipped with an intelligent control system to achieve automatic control and monitoring, thereby ensuring the safe operation of the power system. During peak power demand periods, the prefabricated cabin can provide sufficient power support to ensure the stability of power supply. It is often used in the construction and maintenance of power facilities, as well as in rural power grid upgrades and renovations.

[0003] In a waterproof and heat-insulating prefabricated cabin for electric power equipment disclosed in Chinese utility model patent CN220324956U, a skeleton is used to build the entire cabin, and prefabricated panels are used in combination with thermal insulation layers and other structures to achieve thermal insulation and waterproofing of the entire electric prefabricated cabin. However, in most scenarios, the temperature outside the cabin is lower than the temperature inside the cabin, and the electric equipment in the cabin needs to dissipate heat to ensure the stability of the operation of the electric equipment and reduce the risk of fire. The most common heat dissipation method is ventilation heat dissipation. During ventilation heat dissipation, it is easy for water to seep into the electric prefabricated cabin from the vents in rainy weather. For this reason, we propose a waterproof structure for the electric prefabricated cabin to solve the above problem. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Example 1

[0023] Reference Figure 1-3 A waterproof structure for a prefabricated power cabin, comprising a cabin 1, characterized in that it also comprises an air outlet 2 opened on one side of the cabin 1, an air inlet 3 is arranged on the lower side wall of the cabin 1, and a waterproof component is also arranged on the cabin 1, wherein:

[0024] The waterproof component includes a vertical pipe 4 fixedly connected to the side wall of the cabin body 1, a mounting frame 5 is slidably connected inside the vertical pipe 4, a rain shelter 6 is fixedly connected to the mounting frame 5, a spring rod 7 is also fixedly connected to the side of the cabin body 1 away from the air inlet 3, the upper end of the spring rod 7 is fixedly connected to the rain shelter 6, wherein the spring rod 7 is used to support the end of the rain shelter 6 away from the pry bar 12, and will not affect the downward pressing of the pry bar 12 of the rain shelter 6, mainly used to ensure that the rain shelter 6 remains in a horizontal state, water retaining plates 8 are provided at both ends of the rain shelter 6, and a drainage port is opened on the water retaining plate 8, and a drainage pipe 9 is also connected to the water retaining plate 8 close to the spring rod 7, wherein the drainage port is provided for discharging rainwater to the side of the cabin body 1 away from the air inlet 3 after the rain shelter 6 is filled with rainwater, and the drainage pipe 9 is also used to discharge rainwater, but the inner diameter of the drainage pipe 9 is small, and the drainage efficiency is low. In order to avoid the situation that the rain shield eaves 6 cannot move downward, and to avoid the situation that the rain shield eaves 6 takes a long time to reset after the rain stops, the lower end of the mounting frame 5 is fixedly connected to a connecting rod 10, and the lower end of the connecting rod 10 is fixedly connected to a water baffle 11, and the water baffle 11 is arranged near the air inlet 3, and one side of the cabin body 1 is rotatably connected to a pry bar 12, one end of the pry bar 12 is arranged below the connecting rod 10, and the end of the pry bar 12 away from the connecting rod 10 is rotatably connected to a rotating rod, the side wall of the cabin body 1 is rotatably connected to a sliding sleeve, and the rotating rod is slidably connected to the sliding sleeve, the end of the rotating rod away from the pry bar 12 is fixedly connected to a cover plate 13, and the cover plate 13 is arranged near the air outlet 2. It should be noted that the user can also set a sensor to cooperate with a signal processor to control the ventilation fan to stop running when the waterproof component closes the air inlet 3 and the air outlet 2 in rainy weather to reduce the energy consumption of the equipment.

[0025] The cabin roof of the cabin body 1 is a gable-shaped ceiling 14, and the rain shelter 6 is arranged below the cabin roof. When the cabin roof is a gable-shaped ceiling 14, it is only necessary to arrange the rain shelter 6 on the side close to the air inlet 3. In conventional designs, the air inlet 3 is generally arranged in a position close to the power equipment in the cabin body 1 to ensure the heat dissipation effect.

[0026] Furthermore, the side walls of the cabin 1 close to the air inlet 3 and the air outlet 2 are provided with L-shaped plates 16, and the water baffle 11 and the cover plate 13 are respectively slidably connected to the inner walls of the L-shaped plate 16. By providing the L-shaped plate 16, the water baffle 11 and the cover plate 13 can be limited, so that the water baffle 11 and the cover plate 13 can better seal the air inlet 3 and the air outlet 2, and to a certain extent prevent rainwater blown onto the side wall of the cabin 1 by the wind from flowing downward along the cabin 1 and flowing into the air inlet 3 or the air outlet 2.

[0027] Furthermore, a dustproof net is provided in the air inlet 3, and a drainage groove is provided at the lower end of the dustproof net. Since the air outlet 2 blows out air outward, there is no need to set a dustproof net. The dustproof net is provided at the air inlet 3 to effectively reduce the dust from entering the cabin 1 through the air inlet 3 under normal conditions. When the precipitation is so small that the waterproof component cannot allow it, some raindrops can be blocked by the dustproof net when they are sucked into the air inlet 3, and flow into the drainage groove along the dustproof net and be discharged. When there is dust on the dustproof net, it will have a better adsorption effect on the small number of raindrops that fall, and the dustproof net can also be cleaned to a certain extent by rainwater.

[0028] Example 2

[0029] Reference Figure 4 A waterproof structure for a prefabricated power cabin, comprising a cabin 1, characterized in that it also comprises an air outlet 2 opened on one side of the cabin 1, an air inlet 3 is arranged on the lower side wall of the cabin 1, and a waterproof component is also arranged on the cabin 1, wherein:

[0030] The waterproof component includes a vertical pipe 4 fixedly connected to the side wall of the cabin body 1, a mounting frame 5 is slidably connected inside the vertical pipe 4, a rain shield eave 6 is fixedly connected to the mounting frame 5, a spring rod 7 is also fixedly connected to the side of the cabin body 1 away from the air inlet 3, the upper end of the spring rod 7 is fixedly connected to the rain shield eave 6, both ends of the rain shield eave 6 are provided with water retaining plates 8, and a drainage port is opened on the water retaining plate 8, and a drainage pipe 9 is also connected to the water retaining plate 8 close to the spring rod 7, a connecting rod 10 is fixedly connected to the lower end of the mounting frame 5, a water baffle 11 is fixedly connected to the lower end of the connecting rod 10, and the water baffle 11 is arranged close to the air inlet 3, a pry bar 12 is rotatably connected to one side of the cabin body 1, one end of the pry bar 12 is arranged below the connecting rod 10, and the pry bar 12 is rotatably connected to the end away from the connecting rod 10 There is a rotating rod, and the side wall of the cabin body 1 is rotatably connected with a sliding sleeve, and the rotating rod is slidably connected to the sliding sleeve, and the end of the rotating rod away from the pry bar 12 is fixedly connected with a cover plate 13, and the cover plate 13 is arranged near the air outlet 2. The cabin roof of the cabin body 1 is a flat top, and the upper surface of the cabin body 1 is fixedly connected with an inclined plate 15, and the rain shelter 6 is arranged near the lower end of the inclined plate 15, and vertical edges are arranged on both sides of the inclined plate 15. The angle between the inclined plate 15 and the horizontal plane is 5°. For the flat-top prefabricated power cabin, the inclined plate 15 is arranged to guide rainwater to fall into the rain shelter 6 to ensure the rapid start-up of the rain shelter 6. Since the inclined plate 15 is an additional equipment, too large an angle will affect its wind resistance, and when the angle is small, it can be ensured that most of the rainwater falls into the rain shelter 6 along the inclined plate 15 in conjunction with the vertical edge to ensure the start-up speed of the rain shelter 6.

[0031] In the utility model, in sunny weather, the air outlet 2 and the air inlet 3 are both in an open state, and in rainy weather, when rain falls on the ceiling of the cabin body 1, the rain flows into the rain shield eaves 6 along the ceiling of the cabin body 1, and the greater the rainfall (per unit time), the faster the rain shield eaves 6 is filled, and after a certain amount of rainwater is filled in the rain shield eaves 6, the rain shield eaves 6 moves downward, cooperates with the mounting frame 5 to press the pry bar 12 downward and drives the water baffle 11 to block the air inlet 3, and the pry bar 12 rotates after being pressed, and cooperates with the rotating rod to drive the cover plate 13 to block the air outlet 2, so that even in windy and rainy weather, it can prevent rainwater from entering the air inlet 3. The air inlet 3 or the air outlet 2 enters the interior of the power prefabricated warehouse. It should be noted that the water retaining plate 8 arranged in the rain shelter 6 is used to limit the water level in the rain shelter 6, and the drain outlet is arranged at the end of the rain shelter 6 away from the air inlet 3, and the set drain pipe 9 is used to slowly drain the water in the rain shelter 6 after the rain stops. Then the gravity of the pry bar 12 itself and the elastic force of the spring rod 7 can more quickly drive the rain shelter 6 to reset, so that the heat dissipation equipment in the cabin 1 can operate normally. This design avoids the risk of water seepage in rainy weather without affecting the ventilation and heat dissipation of the power prefabricated warehouse in clear weather, and has a simple and stable structure and low production cost.
