Description

Technical Field

[0001] This invention relates to the field of power equipment technology, specifically to a distribution box. Background Technology

[0002] With the rapid development of the new energy power generation industry, ground-mounted photovoltaic and wind power stations are being built in large numbers in remote areas such as deserts and Gobi. As the core unit of the power distribution system of the power station, the distribution box undertakes the key functions of power distribution, operation monitoring and circuit protection. The existing outdoor distribution box is mainly composed of a cabinet, power distribution component group, intelligent monitoring unit and ventilation and heat dissipation system. The ventilation and heat dissipation system relies on a fan to drive air flow and completes the exchange of internal and external air through the air inlet and air outlet on the cabinet, thereby removing the heat generated by the operation of electrical components in the cabinet and ensuring that the equipment works at a suitable temperature.

[0003] However, in extreme outdoor conditions such as deserts and Gobi, characterized by frequent sandstorms, large diurnal temperature variations, and short periods of high humidity, existing distribution boxes require continuous air exchange with the outside environment to meet heat dissipation needs. External dust and moisture can enter the cabinet through the air inlet and outlet. The dust first forms a layer of dust on the surface of electrical components, terminals, and insulation parts. The poor thermal conductivity of the dust layer directly hinders heat dissipation, leading to a significant increase in equipment operating temperature. Furthermore, condensation caused by diurnal temperature variations and ambient moisture are absorbed by the dust layer, forming a conductive deposit layer on the surface of the components. This significantly reduces the breakdown voltage of the insulation parts, ultimately causing a series of faults such as overheating, insulation breakdown, and short circuits. This severely shortens the service life of the distribution box and restricts the long-term stable operation of new energy power plants. Therefore, it is urgent to design a new type of distribution box. Summary of the Invention

[0004] The purpose of this invention is to provide a distribution box to solve the problems mentioned in the background art regarding the difficulty of simultaneously achieving ventilation and heat dissipation and dust prevention and dehumidification in the extreme working conditions of deserts, Gobi deserts with frequent sandstorms, large temperature differences, and short-term high humidity. Sand and moisture can easily enter the cabinet with the airflow. Dust accumulation will not only hinder the heat dissipation of components and aggravate the temperature rise, but also adsorb moisture to form a conductive deposit layer, causing contact overheating, insulation breakdown, or even short circuit faults, resulting in short overall service life of the equipment and high operation and maintenance costs.

[0015] The beneficial effects that can be achieved by the above embodiments of the present invention include: This invention uses a breathable structure to initially filter air, removing large particles of sand and other foreign matter. By incorporating an air duct structure on the side wall of the isolation chamber, centrifugal force is generated as the airflow moves along the arc-shaped channel, throwing sand and dust tangentially into the accumulation chamber for accumulation. This achieves highly efficient dust removal during the intake phase. The intake and exhaust mechanisms synchronously switch airflow directions under the drive of an electromagnetic catapult, allowing the air duct structures on both sides to alternately perform intake and exhaust functions. During the exhaust phase, the reverse airflow passes through the protective net and flat box, blowing away the sand and dust intercepted by the net and flat box, achieving automatic unblocking. This significantly reduces the risk of sand and dust intruding into the power distribution mechanism, damaging electrical components, and reducing insulation performance. It also reduces the frequency of manual cleaning and maintenance, adapting to the unattended operation requirements of remote power stations, helping to extend the overall service life of the equipment and reduce maintenance costs.

[0016] This invention uses a flat box filled with granular desiccant, which not only intercepts residual fine dust through the gaps between the particles, but also simultaneously adsorbs moisture in the air, achieving integrated dust removal and dehumidification. The intelligent controller uses environmental data monitored by an external hygrometer, anemometer, rain gauge, and light meter to control the electric telescopic rod to automatically pull out the flat box on the exhaust side and isolate it from the main body in dry, sunny, light wind, or windless daytime conditions. The desiccant is then regenerated using natural sunlight. The desiccant on both sides is regenerated alternately, ensuring that the dehumidification process is uninterrupted and that the long-term dehumidification performance is stable and reliable.

[0017] The protective cover of this invention can cover the ventilation window during sandstorms and rain, preventing sand and rainwater from directly invading the protective net. The drainage strip guides and diverts rainwater seeping through the gaps, preventing rainwater from flowing into the ventilation window along the side wall of the isolation box and blocking rainwater from entering the protective net along the wall surface. This provides better dust and moisture protection. The separation mechanism can automatically remove sand at regular intervals, eliminating the need for frequent on-site cleaning. It is suitable for remote, unattended scenarios in new energy power plants, effectively reducing the erosion and damage caused by the coupling of multiple environmental factors such as high temperature, sand, and humidity, and significantly extending the overall service life of the distribution box.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0022] like Figures 1-13 As shown, this application provides a power distribution box, including: a power distribution mechanism 1, a ventilated structure 2 on the top of both the left and right sides of the power distribution mechanism 1, an air passage structure 3 on the inner walls of both the left and right sides of the power distribution mechanism 1, the ventilated structure 2 being connected to the power distribution mechanism 1 through the air passage structure 3, a drying mechanism 4 inside the air passage structure 3, a separation mechanism 5 at the bottom of the air passage structure 3, a protective mechanism 6 on the outside of the ventilated structure 2, an air inlet mechanism 7 at the bottom of the power distribution mechanism 1, an air outlet mechanism 8 at the top of the power distribution mechanism 1, and a conversion mechanism 9 between the air inlet mechanism 7 and the air outlet mechanism 8.

[0023] In operation, external air, driven by the air outlet mechanism 8, enters the bottom of the inner cavity of the power distribution mechanism 1 through the ventilation structure 2, air duct structure 3, and drying mechanism 4 on the left side wall. The ventilation structure 2 performs preliminary filtration of the air, removing large particles of sand and other foreign matter. The separation mechanism 5 removes residual fine sand and dust from the air under centrifugal force. The drying mechanism 4 removes a very small amount of residual sand and dust from the air. Air flows upward from the bottom of the power distribution mechanism 1 through the air inlet mechanism 7, and then air blows across the surface of the power distribution equipment, serving a heat dissipation function. The airflow then passes through the air outlet mechanism 8 and the power distribution... The air duct structure 3, drying mechanism 4, and ventilation structure 2 on the right side wall of mechanism 1 flow out, back-blowing the drying mechanism 4 and ventilation structure 2 on the right side wall of power distribution mechanism 1. This blows away the sand and dust trapped on the drying mechanism 4 and ventilation structure 2, thus cleaning them and clearing blockages. After working for a period of time, the switching mechanism 9 drives the intake mechanism 7 and exhaust mechanism 8 to operate synchronously. Then, external air, driven by the exhaust mechanism 8, enters the inner cavity of power distribution mechanism 1 through the ventilation structure 2, air duct structure 3, and drying mechanism 4 on the right side wall of power distribution mechanism 1. At the bottom, the ventilated structure 2 performs preliminary air filtration, removing large particles of sand and other foreign matter. The separation mechanism 5 removes residual fine sand and dust under centrifugal force. The drying mechanism 4 filters out the very small amount of residual sand and dust. Air flows upward from the bottom of the power distribution mechanism 1 through the air intake mechanism 7, then blows across the surface of the power distribution equipment, providing heat dissipation. Next, the airflow exits through the air outlet mechanism 8 and the air duct structure 3, drying mechanism 4, and ventilated structure 2 on the left side wall of the power distribution mechanism 1, backflushing the drying mechanism 4 and ventilated structure 2 on the left side wall of the power distribution mechanism 1. The sand and dust intercepted on the drying mechanism 4 and the ventilated structure 2 are blown away, which serves to clean the sand and dust on the drying mechanism 4 and the ventilated structure 2, and at the same time, it also serves to clear blockages. The above principle is repeated, so that the ventilated structure 2, the air passage structure 3, and the drying mechanism 4 on the left and right side walls of the power distribution mechanism 1 alternately act as air inlets and outlets. At the same time, the drying mechanism 4 can also dry the air, reducing the moisture entering the power distribution mechanism 1. The protective mechanism 6 shields the sand and dust in harsh environments such as sandstorms, preventing a large amount of sand and dust from impacting the ventilated structure 2, reducing the workload of the ventilated structure 2, and ensuring that the ventilated structure 2 is always permeable.

An isolation box 102 is bolted to the top surface of the mounting frame 101. The mounting frame 101 serves to raise the isolation box 102, thereby keeping the separation mechanism 5 away from the ground. This ensures that when the separation mechanism 5 is opened, the sand and dust collected inside the separation mechanism 5 can slide down under the action of gravity, thereby achieving the function of cleaning the sand and dust inside the separation mechanism 5.

The top of the back strip 405 forms an upper end 409. Small ventilation holes 410 are opened on both the left and right sides of the flat box 403. A replacement window 411 is opened at the top of the front side of the flat box 403. The flat box 403 is filled with granular desiccant to dry the air. At the same time, the gaps between the desiccant particles are used to filter out a very small amount of residual sand and dust in the air, thereby improving the dust removal effect. The replacement window 411 is used to fill or empty the desiccant.

[0032] The isolation box 102 has a recessed groove 412 on its front side. A insertion cavity 413 is formed on the rear side of the recessed groove 412, located above the pull-out groove 401. A through hole 414 is formed on the rear side of the insertion cavity 413. An assembly hole 415 is formed on the rear side of the isolation box 102, communicating with the through hole 414. An electric telescopic rod 416 is inserted into the insertion cavity 413. The front end of the electric telescopic rod 416 is inserted into the recessed groove 412. The rear end of the extension rod of the electric telescopic rod 416 passes through the through hole 414 and extends into the assembly hole 415, where it is fixedly connected to an assembly block 417. A shaped groove 418 is formed on the top surface of the assembly block 417, away from the electric telescopic rod. The end of the rod 416 is open and the opening is located on the side of the assembly block 417 away from the electric telescopic rod 416. A shaped insert 419 is inserted into the shaped groove 418. The shaped insert 419 passes through the opening of the shaped groove 418 away from the electric telescopic rod 416 and is fixedly connected to the side of the upper end 409 located on the side of the flat box 403. A sealing cover 420 is bolted inside the recessed groove 412. The sealing cover 420 presses the front end of the electric telescopic rod 416 into the recessed groove 412. When the electric telescopic rod 416 is extended to its longest state, the flat box 403 is completely pulled out from the pull-out groove 401, the guide bar 404 is completely pulled out from the guide groove 402, and the straightening rod 407 is completely pulled out from the straightening column groove 408.

[0033] The intelligent controller 110 determines, based on monitored data, that the external environment is dry, sunny, with light wind or no wind, and during the day. The intelligent controller 110 then controls the extension of the electric telescopic rod 416 on the drying mechanism 4, which acts as an air outlet. The electric telescopic rod 416, along with the flat box 403, is pulled out of the pull-out slot 401 via the assembly block 417, the irregular groove 418, the irregular insert block 419, the upper end 409, and the back strip 405, until only the tail end of the flat box 403, away from the back strip 405, is inserted into the pull-out slot 401. Then, the electric telescopic rod 416... The controller 110 stops the process, and then the flat box 403, carrying the desiccant inside, is suspended in the air to dry, thus regenerating the desiccant. When the weather conditions are not met (dry, sunny, light wind, or no wind, daytime), or when the air inlet and outlet need to be changed, the intelligent controller 110 controls the electric telescopic rod 416 to retract. The electric telescopic rod 416, through the assembly block 417, the irregular groove 418, the irregular insert block 419, the upper end 409, and the back strip 405, carries the flat box 403 into the pull-out slot 401 until the flat box 403 is fully reset, thus achieving the purpose of automatically regenerating the desiccant.

[0034] When the electric telescopic rod 416 is extended to its longest position, the flat box 403 is fully pulled out of the pull-out groove 401, the guide bar 404 is fully pulled out of the guide groove 402, and the straightening rod 407 is fully pulled out of the straightening column groove 408, people support the flat box 403 and move it upward. The flat box 403 moves upward along with the irregularly shaped insert 419 via the back bar 405 and the upper end 409 until the irregularly shaped insert 419 is completely moved out of the irregularly shaped groove 418. After that, people can remove the whole assembly consisting of the flat box 403, guide bar 404, back bar 405, lower end 406, straightening rod 407, upper end 409, and irregularly shaped insert 419 to replace the desiccant.

[0035] Please see Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 13 The separation mechanism 5 includes a tangential channel 501, which is located inside the side wall of the isolation box 102 and on the side of the inner vertical channel 304 away from the outer vertical channel 302. The tangential channel 501 extends along the tangential direction of the arc channel 303. A buffer cavity 502 is provided at the end of the tangential channel 501 away from the arc channel 303. An accumulation cavity 503 is provided at the bottom of the buffer cavity 502. Sand and dust in the air pass through the tangential channel 501 and enter the buffer cavity 502 under the combined action of centrifugal force and gravity, and gradually accumulate inside the accumulation cavity 503.

[0036] The bottom surface of the accumulation chamber 503 is provided with an inclined bottom surface 504. The accumulated sand and dust slide down along the inclined bottom surface 504 under the action of gravity, creating favorable conditions for automatic sand and dust removal.

[0037] The end of the accumulation chamber 503 away from the buffer chamber 502 is open, and the opening is located on the side of the isolation box 102. A fixed base plate 505 is fixedly connected to the top surface of the inner cavity of the accumulation chamber 503. A fixed flat groove 506 is formed on the bottom surface of the fixed base plate 505. An electromagnet 507 is fixedly connected to the middle of the top surface of the inner cavity of the fixed flat groove 506. The electromagnet 507 is electrically connected to the intelligent controller 110. A telescopic plate 508 is inserted into the fixed flat groove 506. The bottom end of the telescopic plate 508 extends out from the bottom end of the fixed flat groove 506 and has a mating slope 509 on its bottom end surface. The mating slope 509 abuts against... A fixed insertion hole 510 is provided on the top surface of the telescopic plate 508, which is attached to the inclined bottom surface 504. A guide column 511 is slidably inserted into the fixed insertion hole 510. The top end of the guide column 511 is fixedly connected to the top surface of the inner cavity of the fixed flat groove 506. A compression spring 512 is movably sleeved on the outside of the guide column 511. The top end of the compression spring 512 abuts against the top surface of the inner cavity of the fixed flat groove 506, and the bottom end of the compression spring 512 abuts against the top surface of the telescopic plate 508. The compression spring 512 is in a compressed state. A permanent magnet is fixedly connected to the middle of the top surface of the telescopic plate 508. The permanent magnet corresponds to the electromagnet 507.

[0038] The electromagnet 507 on the separation mechanism 5, which corresponds to the air passage structure 3 that acts as the air outlet, is opened once every certain period of time under the control of the intelligent controller 110. When it is opened, the electromagnet 507 applies an upward pulling force to the telescopic plate 508 through the magnetic attraction between it and the permanent magnet plate. Then the telescopic plate 508 moves upward, and a material drop port is formed between the docking slope 509 and the inclined bottom surface 504. Then the sand and dust on the inclined bottom surface 504 slide out. At the same time, the airflow inside the air passage structure 3 applies a pushing force to the sand and dust on the inclined bottom surface 504, helping the sand and dust to slide out. Then the intelligent controller 110 controls the electromagnet 507 to close. Then the telescopic plate 508 moves downward under the action of gravity and the elastic force of the pressure spring 512 until the docking slope 509 presses against the surface of the inclined bottom surface 504, closing the material drop port and realizing the purpose of automatically removing sand and dust from the separation mechanism 5.

[0039] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 12The protective mechanism 6 includes a protective cover 601, which covers the ventilation window 201. In harsh environments such as sandstorms, the protective cover 601 blocks sand and dust, prevents a large amount of sand and dust from impacting the protective net 202, reduces the workload of the protective net 202, ensures that the protective net 202 is always transparent, and also serves to protect against wind and rain.

[0040] The protective cover 601 is slidably connected to the side of the isolation box 102. Two pressure plates 602 are fixedly connected to the inner wall of the protective cover 601. The two pressure plates 602 are respectively pressed onto the front and rear ends of the protective net 202 to fix the protective net 202. Wing strips 603 are fixedly connected to both the front and rear ends of the protective cover 601. Angle strips 604 are slidably fastened to the outside of the wing strips 603. The angle strips 604 are fixedly connected to the side of the isolation box 102. The bottom end of the angle strips 604 is fixedly connected to a limiting end plate 605. The bottom end of the wing strips 603 abuts against the top surface of the limiting end plate 605, so that the protective cover 601 can move upward to expose the protective net 202 so that people can replace the protective net 202.

[0041] Inside the protective cover 601, there is a drain strip 606 located between two pressure plates 602. The drain strip 606 is fixedly connected to the side of the isolation box 102 and located above the ventilation window 201. The end face of the drain strip 606 is a right-angled triangle shape, which guides the rainwater that leaks from the gap between the protective cover 601 and the isolation box 102, so that the leaked rainwater flows down from a position away from the protective net 202, preventing rainwater from entering the protective net 202 along the surface of the isolation box 102, and reducing the moisture entering the power distribution mechanism 1 in the rainy environment.

[0042] Please see Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8The air intake mechanism 7 includes a lower boss 701, which is fixedly inserted into the middle of the bottom wall of the inner liner box 105.
