Description

Technical Field

[0001] The utility model relates to the technical field of power distribution equipment, in particular to a double waterproof integrated power distribution box. Background Art

[0002] An integrated distribution box is a complete set of equipment that houses circuit breakers, fuses, leakage protectors, electric meters, contactors, voltage stabilizers and other electrical components. As the terminal distribution unit of the power system, it is responsible for distributing the electrical energy of the main circuit to each branch circuit, while also providing protection against overload, short circuit, leakage and other issues.

[0003] In the existing technology, integrated distribution boxes are usually equipped with heat dissipation vents to ensure heat dissipation of equipment, but the existence of heat dissipation vents also becomes the main channel for rainwater to seep in. The heat dissipation vents of traditional distribution boxes mostly adopt a fixed louver structure, whose blade angle is fixed and the gap spacing makes it difficult to take into account both waterproofing and ventilation requirements. In light rain or windless environment, the louvers can use their own tilt angle to block vertically falling rainwater, but in severe weather such as heavy rain and strong winds, rainwater is prone to form oblique water flow or water mist. When the wind direction is consistent with the angle of the louver gap, the water flow can directly pass through the blade gap and invade the box. Especially in typhoon-prone areas, the impact of rainwater carried by high-speed airflow is extremely strong, and the passive blocking method of fixed louvers is difficult to resist this oblique penetration. After the rainwater seeps in, it will adhere to the surface of the electrical components, causing insulation performance to deteriorate or even short circuit failure. Utility Model Content

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0023] 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 disclosed in the following specification.

[0024] Example 1, according to Figure 1-Figure 5 As shown, a double waterproof integrated distribution box includes a distribution box body 1, a waterproof component 5 is provided inside the distribution box body 1, and a rain guide component 6 is provided at the bottom of the inner wall of the distribution box body 1;

[0025] The waterproof component 5 includes a heat dissipation vent 51 symmetrically opened on the outer wall of the distribution box body 1. The inner wall of the heat dissipation vent 51 is vertically equidistantly connected to a number of louver baffles 501 through a rotating shaft. The outer walls of the several louver baffles 501 are fixedly connected to a connecting plate 502. The outer walls of the several connecting plates 502 are rotatably connected to a fixing bar 503 through a rotating shaft. The outer wall of the fixing bar 503 is fixedly connected to a fixing block 504. The outer wall of the distribution box body 1 is symmetrically installed with an electric push rod 505. The bottom of the inner wall of the heat dissipation vent 51 is fixedly installed with a rain shield 506 near the inside of the distribution box body 1. The output end of the electric push rod 505 is fixedly connected to the top of the fixed block 504. The outer wall of the distribution box body 1 is symmetrically fixed with an inclined protective frame 507. The bottom of the inner wall of the inclined protective frame 507 is provided with a number of rain guide grooves 508. The outer walls of the several louver baffles 501 are in contact with each other.

[0026] The entire embodiment 1 achieves the following effects: the waterproof assembly 5, through its multi-layered structure, forms a highly effective protection system that specifically addresses the problem of rainwater infiltration through conventional heat dissipation vents 51. The inclined protective frame 507 intercepts most rainwater that directly hits the heat dissipation vents 51. The rain gutter 508 quickly drains accumulated water from the frame, preventing it from stagnating and then infiltrating. The louver baffles 501, driven by the electric push rod 505, can be flexibly adjusted. When heat dissipation is not required or during heavy rain, the baffles contact and close the heat dissipation vents 51, forming a double barrier with the inner rain shield 506, completely blocking the path for rainwater infiltration. When heat dissipation is required, the baffles open to form a ventilation channel, while the rain shield 506 can still intercept oblique splashing water droplets. This design not only ensures heat dissipation requirements, but also significantly improves the waterproof capability of the distribution box in various weather conditions, effectively reducing electrical failures caused by rainwater infiltration.

[0027] Example 2, according to Figure 5 As shown, the rain guide assembly 6 includes an inclined plate 601 symmetrically fixedly connected to the bottom of the distribution box, a water collecting trough 602 is fixedly connected between the two inclined plates 601, a hydrophobic inclined plate 603 is fixedly connected to the inside of the water collecting trough 602, and water outlet holes 604 are symmetrically opened at the bottom of the inner wall of the water collecting trough 602. The bottom of the water outlet hole 604 is fixedly connected to a water outlet pipe 605, the top of the water outlet pipe 605 is fixedly connected to the bottom of the distribution box body 1, and the inner wall of the water outlet pipe 605 is provided with a solenoid valve 606. The top of the distribution box body 1 is fixedly connected to a protective top 7, the protective top 7 is designed to be inclined on both sides, and the outer wall of the protective top 7 is provided with several strip grooves 701. The outer wall of the distribution box body 1 is provided with a box door 2, the outer wall of the box door 2 is fixedly connected to a transparent observation window 3, and the outer wall of the distribution box body 1 is fixedly connected to a handle 4.

[0028] The effect achieved by the entire embodiment 2 is as follows: the rain guide component 6 focuses on quickly handling rainwater that accidentally seeps into the box, avoiding damage to internal components caused by accumulated water. The inclined plate 601 can efficiently guide the rainwater scattered in the box along the inclined surface to the water collection tank 602, preventing rainwater from flowing freely at the bottom of the box. The hydrophobic inclined plate 603 in the water collection tank 602 can accelerate the convergence of water flow, so that rainwater can quickly flow to the water outlet 604, and then be discharged out of the box through the outlet pipe 605. The solenoid valve 606 can control the drainage timing according to the water accumulation situation, ensuring that the accumulated water is discharged in time and avoiding external water vapor from flowing back through the outlet pipe 605. The entire component forms a complete internal drainage path, which significantly improves the distribution box's ability to respond to accidental water seepage, ensures that the internal electrical components are in a dry environment, and extends the service life of the equipment.

[0029] The working principle of the entire device is as follows: in daily rainless or low-humidity environments, when the distribution box needs to dissipate heat, the electric push rod 505 is in working condition, and its output end drives the fixing bar 503 to move downward through the fixing block 504, and the fixing bar 503 then synchronously pulls a number of louver baffles 501 to rotate around the rotating shaft through the connecting plate 502, so that the louver baffles 501 are in an open state. At this time, a ventilation gap is formed between adjacent louver baffles 501, and the internal heat of the distribution box body 1 diffuses outward through the heat dissipation port 51, and the external cold air enters the heat dissipation port 51 through the inclined protective frame 507 to supplement, forming air convection to complete the heat dissipation. In this process, the inclination angle of the inclined protective frame 507 can block some dust and oblique airflow, and the rain shield 506 further intercepts trace water droplets that may splash into the box, ensuring basic protection during heat dissipation. When it rains, the top protective roof 7 guides most of the rainwater to the edge through the inclined design on both sides. The strip groove 701 can quickly divert rainwater to prevent rainwater from being retained at the heat dissipation outlet 51 and seeping into the side wall of the box. At the same time, the inclined protective frame 507 serves as the first line of defense. Its inclined structure can block rainwater that directly hits the heat dissipation outlet 51. A small amount of rainwater that enters the protective frame will flow into the rain guide groove 508 along the inner wall and be quickly discharged to the outside of the box through the rain guide groove 508. At this time, the electric push rod 505 contracts, driving the fixing block 504 and the fixing bar 503 to move upward, and the connecting plate 502 pushes the louver baffle 501 to rotate synchronously until they are in close contact with each other, completely closing the heat dissipation outlet 51 and cooperating with the rain shield 506 inside the heat dissipation outlet 51 to form a double barrier, completely blocking the path for rainwater to seep into the heat dissipation outlet 51.

[0030] If a small amount of rainwater accidentally penetrates the outer defense line and seeps into the box, the inclined plate 601 at the bottom will play a diversion role, guiding the rainwater along the inclined surface into the water collection tank 602. The hydrophobic inclined plate 603 in the water collection tank 602 accelerates the water flow through the inclined angle, so that the rainwater flows quickly to the water outlet holes 604 on both sides and is then discharged out of the box through the outlet pipe 605. The solenoid valve 606 can automatically open or close according to the humidity inside the box or the water accumulation monitoring signal, ensuring timely drainage and preventing external water vapor from flowing back through the outlet pipe 605.

[0031] When the rainfall ends, the electric push rod 505 extends outward again to drive the louver baffle 501 to open, restoring the heat dissipation function. At this time, the rain shield 506 can still intercept any remaining raindrops or moisture to ensure a dry environment in the box.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any other form. 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 of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
