Technical Field
[0001] This utility model relates to the field of power engineering substation technology, and in particular to a waterproof box-type substation for power engineering. Background Technology
[0002] In the field of modern power engineering, prefabricated substations are widely used in urban power grid upgrades, industrial power supply, and various temporary power supply sites due to their advantages such as small footprint, convenient installation, and flexible combination. The electrical equipment inside a prefabricated substation continuously generates heat during operation. To ensure stable operation and extend the service life of the equipment, good ventilation and heat dissipation are crucial. Currently, most prefabricated substations use louvers as their ventilation structure. Louvers can achieve air circulation to a certain extent, effectively removing heat from the interior and ensuring that the electrical equipment operates in a suitable temperature environment.
[0003] However, the existing louvered ventilation structure has significant defects. In rainy weather, especially during heavy or continuous rainfall, rainwater can easily enter the interior of the box-type substation through the gaps in the louver blades. The rainwater may drip onto the electrical equipment, causing short circuit faults, seriously affecting the normal operation of the equipment, and may even damage the equipment, causing large-scale power outages. Utility Model Content
[0004] In view of the shortcomings of the prior art, rainwater can easily enter the interior of the prefabricated substation through the gaps in the louvers. The rainwater may drip onto the electrical equipment, causing short circuits, seriously affecting the normal operation of the equipment, and even causing equipment damage and large-scale power outages. This utility model provides a prefabricated substation for power engineering with good waterproof performance. It has the advantages of easy opening or closing of the ventilation structure and optimized waterproof performance, thus solving the problems mentioned in the prior art.
[0005] This utility model provides the following technical solution: a waterproof box-type substation for power engineering, comprising a substation body, on both sides of which ventilation slots are symmetrically provided, and multiple sealing plates are evenly provided on the inner side of the ventilation slots. A support rod is fixedly connected to the upper end of each sealing plate. Multiple bearing seats are symmetrically installed at both ends of the inner side of the ventilation slots. The two sides of the support rod are rotatably connected to the inner side of the bearing seats. A rectangular slot is provided on one side of the ventilation slot. A brake gear is fixedly installed on the side of the support rod near the rectangular slot. Multiple partition plates are evenly fixedly installed inside the rectangular slot. A forward and reverse motor is provided at the bottom of the rectangular slot. A threaded rod is connected to the output end of the forward and reverse motor. The upper end of the threaded rod passes through multiple partition plates and is rotatably connected to the upper end of the rectangular slot. A rack plate is meshed with the side of each brake gear. A limit slider is fixedly installed on the inner side of each rack plate. A screw hole block is fixedly installed on the upper side of the limit slider. The surface of the threaded rod is threadedly connected to the interior of the multiple screw hole blocks.
[0006] Preferably, a plurality of T-shaped slide rails are fixedly installed inside the rectangular groove, and the limiting slider is slidably connected to the surface of the T-shaped slide rails.
[0007] The limit slider is slidably connected to the surface of the T-shaped slide rail, providing precise guidance for the movement of the rack plate and strictly limiting the movement of the rack plate to the trajectory specified by the T-shaped slide rail.
[0008] Preferably, the substation body has a hinged door on its front surface.
[0009] Preferably, the substation body has multiple water guide channels evenly distributed at its bottom interior, and the inner sides of the multiple water guide channels are designed with an inverted V-shaped structure.
[0010] With the design of the water channel, the accumulated water will naturally flow to the lower-lying area under the action of gravity. Since the water channel is inverted V-shaped, the accumulated water will flow to both sides along the inverted V-shaped slope.
[0011] Preferably, water collection troughs are provided on both sides of the bottom of the substation body, and the two sides of the water guide trough are respectively connected to the upper ends of the two water collection troughs.
[0012] Preferably, a drain pipe is fixedly installed on one side of the bottom of the water collection tank, the other end of the drain pipe extends through the outside of the substation body, and a valve is provided on the inside of the drain pipe.
[0013] With the installation of the drainage pipe, once the water collection tank has collected a certain amount of water, the valve inside the drainage pipe is opened, and under the action of gravity, the water in the water collection tank will be discharged to the outside of the substation body through the drainage pipe.
[0014] This utility model has the following advantages:
[0015] 1. By installing multiple sealing plates inside the ventilation slot, and driving a threaded rod with a reversible motor to move a rack plate meshing with a brake gear, the opening and closing of the sealing plates is controlled. Under normal weather conditions, the multiple sealing plates are open, ensuring ventilation and heat dissipation of the prefabricated substation. In rainy weather, the starting motor reverses the screw block to move the rack plate down along the T-shaped slide rail. In conjunction with the brake gear and rack plate, the sealing plates are driven to gradually rotate from the open state until they completely cover the ventilation slot, thus closing the ventilation slot. This effectively prevents rainwater from entering the substation through the ventilation opening, significantly reducing the risk of equipment damage, ensuring the stability of power supply, and reducing the occurrence of large-scale power outages.
[0016] 2. By installing multiple water guide channels inside the substation, small amounts of water entering from various places can be quickly collected. Utilizing the structure of the water guide channels, the water will automatically flow to both sides along the slope. Through connection and cooperation with the bottom water collection channel, the water is collected in a concentrated manner. Then, by using the drain pipe installed on the side of the water collection channel, the valve can be opened when drainage is needed, so that the water can be discharged to the outside of the substation in a timely manner, maintaining a dry internal environment, effectively preventing electrical equipment from being damaged by moisture, and extending the service life of the equipment.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-4 A waterproof box-type substation for power engineering includes a substation body 1. Ventilation slots 3 are symmetrically arranged on both sides of the substation body 1. Multiple sealing plates 4 are evenly arranged on the inner side of the ventilation slots 3. By setting multiple sealing plates 4 on the inner side of the ventilation slots 3, a forward / reverse motor 11 drives a threaded rod 12, which in turn moves a rack plate 10 meshing with a brake gear 7, thereby controlling the opening and closing of the sealing plates 4. A support rod 5 is fixedly connected to the upper end of the sealing plate 4. Multiple bearing seats 6 are symmetrically installed at both ends of the inner side of the ventilation slots 3. The two sides of the support rod 5 are rotatably connected to the inner side of the bearing seats 6, providing a stable support point for the support rod 5. During the rotation of the sealing plate 4 with the support rod 5, the bearing seats 6 reduce the frictional force during the rotation of the support rod 5, making the opening and closing of the sealing plate 4 smoother. A rectangular slot 8 is opened on one side of the ventilation slot 3, and a brake gear 7 is fixedly installed on the side of the support rod 5 near the rectangular slot 8.
[0025] Please see Figures 3-5 Multiple partition plates 9 are evenly fixedly installed inside the rectangular groove 8. A forward and reverse motor 11 is provided at the bottom of the rectangular groove 8. The output end of the forward and reverse motor 11 is connected to a threaded rod 12. The upper end of the threaded rod 12 passes through multiple partition plates 9 and is rotatably connected to the upper end of the rectangular groove 8. The sides of the brake gear 7 are meshed with rack plates 10. The partition plates 9 limit the rack plates 10 to prevent them from moving excessively and causing the sealing plate 4 to have an excessively large angle. Because the brake gear 7 meshes with the rack plate 10, the linear motion of the rack plate 10 is converted into the rotational motion of the brake gear 7, which in turn drives the support rod 5 to rotate, realizing the opening or closing of the sealing plate 4 to the ventilation groove 3. When closed, limit sliders 13 are fixedly installed on the inner side of the rack plate 10. Screw holes 15 are fixedly installed on the upper side of the limit sliders 13. The surface of the threaded rod 12 is connected to the internal threads of multiple screw holes 15. In rainy weather, the starting motor reverses the screw holes 15 to drive the rack plate 10 to move downward along the T-shaped slide rail 14. In conjunction with the brake gear 7 and the rack plate 10, the sealing plate 4 is driven to gradually rotate from the open state until the ventilation slot 3 is completely covered, so that the sealing plate 4 closes the ventilation slot 3, effectively preventing rainwater from entering the substation through the ventilation opening, greatly reducing the risk of equipment damage, ensuring the stability of power supply, and reducing the occurrence of large-scale power outages.
[0026] Please see Figures 4-5Multiple T-shaped slide rails 14 are fixedly installed inside the rectangular groove 8. The internal sliding block 13 is slidably connected to the surface of the T-shaped slide rail 14. The sliding block 13 slides on the T-shaped slide rail, effectively restricting the movement trajectory of the rack plate 10, so that it can only move smoothly along the direction of the slide rail, avoiding the rack plate 10 from deviating, shaking or jamming during movement. The front surface of the substation body 1 is hinged with a switch door 2, which provides convenience for the maintenance and repair work inside the equipment.
[0027] Please see Figures 1-2 Multiple water guide channels 16 are evenly distributed at the bottom of the substation body 1. The inner side of the multiple water guide channels 16 is designed with an inverted V-shaped structure. Water collection channels 17 are provided on both sides of the bottom of the substation body 1. The two sides of the water guide channels 16 are respectively connected to the upper ends of the two water collection channels 17. A drain pipe 18 is fixedly installed on one side of the bottom of each water collection channel 17. The other end of the drain pipe 18 passes through the outside of the substation body 1. A valve is provided on the inner side of the drain pipe 18. By setting multiple water guide channels 16 inside the substation body 1, a small amount of water entering from various places can be quickly collected. Utilizing the structure of the water guide channels 16, the water will automatically flow to both sides along the slope. By connecting with the bottom water collection channels 17, the water will be collected in a concentrated manner. Then, by using the drain pipe 18 installed on the side of the water collection channel 17, the valve can be opened when drainage is needed, so that the water can be discharged to the outside of the substation in a timely manner, maintaining a dry internal environment, effectively preventing electrical equipment from being damaged by moisture, and extending the service life of the equipment.
[0028] Working Principle: In actual use, first start the forward and reverse motor 11, which drives the threaded rod 12 to rotate forward. Since the threaded rod 12 is threadedly connected to the screw hole block 15 on the rack plate 10, as the threaded rod 12 rotates, the screw hole block 15 drives the rack plate 10 to move upward along the T-shaped slide rail. During the upward movement of the rack plate 10, the force generated is transmitted to the brake gear 7, causing the brake gear 7 to rotate and drive the support rod 5 to rotate synchronously. The rotation of the support rod 5 causes the sealing plate 4 to rotate and open around the support rod 5. Multiple sealing plates 4 open synchronously, allowing the ventilation slot 3 to open, so that the air inside and outside the box-type substation can circulate, realizing the ventilation and heat dissipation function. To prevent rainwater from entering the box-type substation through the ventilation slot 3, the motor reverses, driving the threaded rod 12 to rotate in the opposite direction, which in turn causes the screw hole block 15 to drive the rack plate 10 to move upward along the T-shaped slide rail. Moving downwards causes the sealing plate 4 to rotate in the opposite direction around the support rod 5, gradually rotating from the open state until it completely covers the ventilation slot 3, thus closing the ventilation slot 3 and effectively preventing rainwater from entering the substation. In addition, if water accumulates inside the box-type substation, the water will flow to both sides under gravity along the slope of the water guide 16 due to the multiple inverted V-shaped water guide troughs 16 installed at the bottom of the substation. The two sides of the water guide trough 16 are connected to the water collection trough 17 at the bottom, and the water will flow into the water collection trough 17 for collection. When drainage is needed, the valve inside the drain pipe 18 is opened, and the water in the water collection trough 17 is discharged to the outside of the substation through the drain pipe 18, keeping the inside of the substation dry and preventing electrical equipment from being damaged by moisture.
