Description

Technical Field

[0001] This invention relates to the field of power distribution equipment technology, specifically to an outdoor power distribution cabinet with automatic wind and sand protection, self-cleaning, and rainwater collection and atomization cooling functions. Background Technology

[0002] Outdoor distribution cabinets are exposed to the elements for extended periods, directly facing harsh environments such as direct sunlight, high temperatures, sandstorms, and heavy rain. Existing traditional outdoor distribution cabinets suffer from several drawbacks: conventional cabinets rely solely on a single-layer outer shell for protection, lacking active shielding mechanisms. In windy and sandy weather, dust continuously adheres to the cabinet surface, seeping into door gaps and ventilation holes, easily causing short circuits due to dust accumulation in internal components. In summer, intense sunlight causes a rapid increase in internal temperature, leading to accelerated aging of electrical components such as circuit breakers and transformers due to prolonged high-temperature operation, significantly increasing the probability of tripping due to faults. In some areas, the large temperature difference between day and night can cause condensation on the cabinet and the accumulation of dust, leading to metal corrosion and oxidation of wiring terminals. Dust and mud adhering to the cabinet's exterior require regular manual cleaning from elevated positions, resulting in high inspection and maintenance costs and low efficiency in areas such as the field, mountains, and remote base stations. Manual cleaning also poses safety hazards due to working at heights and cannot be done in real time, leading to long-term dust accumulation and continuous damage to the equipment. In summary, existing outdoor distribution cabinets lack an integrated intelligent protection structure that combines environmental sensing, partial shielding, automatic cleaning, and rainwater harvesting and atomization cooling, resulting in insufficient practicality and intelligence, and urgently requiring improvement. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention proposes an outdoor power distribution cabinet that integrates intelligent protection with features such as multi-faceted shielding, automatic cleaning, and rainwater recycling and atomization cooling.

[0004] The technical solution used in this invention is as follows: an outdoor power distribution cabinet includes a cabinet body, a control box fixed to the top of the cabinet body, and a control module inside the control box; four sides of the control box are respectively provided with a hanging shielding mechanism for shielding and protecting each side of the cabinet body; the hanging shielding mechanism includes a hollow structure winding drum rotatably installed inside the control box, a shielding layer wound on the winding drum, and a hollow structure counterweight cylinder fixed to the bottom end of the shielding layer; several water pipes are attached to the shielding layer, and the water pipes are wound and extended synchronously with the shielding layer; the top end of the water pipe is connected to the winding drum, and the bottom end is connected to the counterweight cylinder to spray water mist onto the cabinet body; a collection and transmission mechanism is provided in the central area inside the control box, which is connected to the winding drum on each hanging shielding mechanism to transmit water source; four sides of the control box are also provided with a cleaning mechanism, and the cleaning mechanisms in opposite positions form a group. The cleaning mechanism includes a scraper telescopically installed on the control box and a control component installed inside the control box, and the control component performs coordinated control of each group of cleaning mechanisms.

[0005] Furthermore, magnetic blocks are fixed on the four sides of the bottom of the cabinet, and the magnetic blocks are provided with limiting grooves that can cooperate with the counterweight cylinder. The top of the magnetic blocks is provided with guide slopes for guidance.

[0006] Furthermore, each side of the control box is provided with a take-up and release groove that allows the shielding layer to pass through. Electromagnetic sliding shafts are fixed at both ends of the take-up and release grooves. The electromagnetic sliding shafts are used to limit and fix the counterweight cylinder. Guide rollers for support and guidance are provided inside the take-up and release grooves.

[0007] Furthermore, the counterweight cylinder has an atomizing nozzle on its circumferential area and a fixing hole at its end, and the electromagnetic sliding shaft can be engaged with the fixing hole.

[0008] Furthermore, the hoisting shielding mechanism includes a winding box fixed inside the control box, a winding drum rotatably installed inside the winding box, a winding motor fixed at one end of the winding box for driving the winding drum; and a connecting box at the other end of the winding box that is rotatably connected to the winding drum, the connecting box being connected to the collection and transmission mechanism.

[0009] Furthermore, the collection and transmission mechanism includes a water collection tank fixed on the control box, a filter plate for filtering out impurities is provided on the inner side of the top of the water collection tank, and a detection module for detecting the environmental climate is provided on the outer side of the water collection tank; a transmission pump is provided at the bottom of the water collection tank, and the tank and the transmission pump are connected by a transmission pipe.

[0010] The detection module integrates multiple types of environmental sensors, communicates with the control module via wired connection, collects outdoor environmental parameters in real time, and transmits the data synchronously. Its detailed functions are as follows: Meteorological parameter collection It integrates wind speed and direction sensors, dust concentration sensors, light intensity sensors, rainfall sensors, and ambient temperature and humidity sensors; it can identify working conditions such as strong winds, blowing sand, strong sunlight exposure, rainfall, and high temperatures in real time.

[0011] Cabinet operating condition data collection The system connects to the internal temperature probe of the cabinet and the water level sensor of the water collection tank to simultaneously collect data on the operating temperature of the components inside the cabinet and the water storage capacity of the water collection tank.

[0012] Data preprocessing and transmission The system performs noise reduction and analog-to-digital conversion on the collected analog signals, and sends the standardized digital signals to the control module in real time. When the threshold is exceeded, an early warning signal is triggered, and a protection start command is pushed out first.

[0013] Regional operating condition identification By accurately determining which side of the cabinet is affected by wind and sand or strong sunlight using wind direction data, the control module can be configured to implement zoned control for the separate deployment of the single-sided shielding layer.

[0014] The control module is the central processing and execution hub of this device. It receives all data collected by the detection module, has a built-in preset control logic program, and uniformly schedules all actuators, including the winding motor, transfer pump, control motor, and electromagnetic sliding shaft. Specifically: Intelligent environmental protection logic control In windy and sandy conditions: It receives signals of dust concentration and wind direction, lowers the windward side shielding layer separately, and keeps the other sides rolled up; after the dust concentration drops to a safe threshold, it automatically starts the rolling process and simultaneously triggers the cleaning mechanism to scrape and wash the shielding layer.

[0015] High light and high temperature conditions: When the light intensity exceeds the standard, lower all the shielding layers to isolate heat radiation; when the temperature inside the cabinet exceeds the set threshold and the water level in the collection tank meets the standard, start the transfer pump to spray mist and cool down.

[0016] Rainfall conditions: The rain sensor detects rainfall and opens the water inlet channel of the collection tank to collect rainwater.

[0017] Rainwater cooling system linkage control Read the water level sensor signal of the water collection tank. If the water level is lower than the safety limit, lock the transmission pump and prohibit atomizing spraying. When the water level meets the standard or the temperature exceeds the limit, start the transmission pump and the corresponding side winding drum to supply water in sequence, and the atomizing nozzle will continuously spray to dissipate heat. After the temperature drops back to the safety value, automatically shut off the water circuit and the shielding mechanism.

[0018] Clearing mechanism coordinated drive control Send forward and reverse timing commands to the control motor to precisely control the alternating extension and retraction of two sets of oppositely set cleaning mechanisms; during the winding process of the shielding layer, synchronously drive the scraper to adhere to the curtain surface to complete the removal of mud, sand and dust.

[0019] Barrier layer retraction and locking control The four-sided winding motors can be independently started and stopped to achieve differentiated lowering of single-sided / multi-sided / four-sided shielding layers; after the counterweight cylinder falls into the magnetic block limiting groove, a magnetic attraction energizing signal is sent to attract and fix it; after the shielding layer is completely wound into place, the electromagnetic sliding shaft is driven to extend and insert into the counterweight cylinder fixing hole to complete mechanical locking and prevent loosening in strong winds.

[0020] Fault self-diagnosis and early warning function Real-time monitoring of the operating current and voltage of the winding motor, transfer pump, control motor, and sensors; local audible and visual warnings in case of stall, water shortage, or sensor disconnection, while recording fault codes for easy later maintenance; automatic retraction of all shielding layers in extreme fault conditions to restore basic heat dissipation of the cabinet.

[0021] Furthermore, the cleaning mechanism includes a slide that is slidably fitted to the side of the control box, the end of the slide being fixedly connected to the scraper, and a spring for providing a reset force is connected between the slide and the inside of the control box; each set of cleaning mechanisms is connected to the control component through steel wire one and steel wire two respectively.

[0022] Furthermore, the control assembly includes a control motor fixed inside the control box and a rotating shaft rotatably installed inside the control box. The control motor drives the rotating shaft rotatably via a belt structure. Control cylinders rotatably are fixed to both ends of the rotating shaft rotatably. A steel wire rotatably winds around the control cylinder rotatably, with its middle section wound around the control cylinder rotatably. Both ends of the steel wire rotatably connect to the slide of one of the cleaning mechanisms. A rotating shaft rotatably is installed inside the control box and outside the two control cylinders rotatably. A gear rotatably is fixed to the rotating shaft rotatably. A gear rotatably is fixed to the end of the control cylinder rotatably. The gear rotatably meshes with the gear rotatably. Control cylinders rotatably are fixed to both ends of the rotating shaft rotatably. A steel wire rotatably winds around the control cylinder rotatably. Its free end is connected to the slide of another set of cleaning mechanisms. When the rotating shaft rotatably rotates forward and backward, it alternately controls the movement of each set of cleaning mechanisms.

[0023] The beneficial effects of this invention compared with the prior art are: (1) This invention sets up a detection module to collect wind direction, dust, and light data in real time. The control module can lower the shielding layer on one side of the cabinet separately, without having to unfold all four sides, to specifically block wind and sand and strong light. After the shielding layer is lowered, the counterweight cylinder is attracted and fixed by the bottom magnetic block, preventing the cabinet from shaking and impacting in strong winds, effectively reducing dust entering the heat dissipation gap of the cabinet, reducing the probability of short circuits and high-temperature aging failures of components due to dust accumulation, and extending the service life of electrical components inside the distribution cabinet; (2) When the shielding layer is rolled up, the control component drives two sets of scrapers to alternately stick to the curtain surface, automatically scraping off the dust and mud stains on the surface of the shielding layer, without requiring maintenance personnel to climb up for cleaning; it is especially suitable for distribution cabinet deployment scenarios such as mountainous areas, outdoor base stations, and roadsides where inspection is inconvenient, greatly reducing manual maintenance costs and eliminating In addition to the safety hazards of high-altitude cleaning, the shielding layer is guaranteed to be transparent, heat dissipated and clean for a long time; (3) The top water collection tank is equipped with a filter plate to collect natural rainwater and filter out large particles such as leaves and mud; Under high temperature conditions, the recycled rainwater is used to spray the cabinet surface, and the cabinet radiant heat is removed by water mist evaporation. Compared with traditional external air conditioners and continuously running cooling fans, there is almost no additional power consumption. It can also be used independently in the field where there is no tap water network. Water resources are recycled, which is energy-saving and environmentally friendly; (4) The detection module collects environmental and equipment operating data in multiple dimensions. The control module has a set of logic programs built in, which automatically switches between shielding, cleaning and cooling modes. No manual operation is required throughout the process; It can be interlocked and controlled according to multiple conditions such as sand and dust concentration, cabinet temperature and water level to avoid invalid equipment start and stop and improve the automation and intelligence level of the equipment.

[0037] The collection and transmission mechanism includes a water collection tank 5 fixed on the control box 3. The inner side of the top of the water collection tank 5 is provided with a filter plate 6 for filtering out impurities, and the outer side of the water collection tank 5 is provided with a detection module 4 for detecting the environmental climate. The bottom of the water collection tank 5 is provided with a transmission pump 501, and the connecting box 16 and the transmission pump 501 are connected by a transmission pipe.

[0038] The cleaning mechanism includes a slide 11 that slides on the side of the control box 3. The end of the slide 11 is fixedly connected to the scraper 10. A spring 17 for providing a reset force is connected between the slide 11 and the inside of the control box 3. Each set of cleaning mechanisms is connected to the control component through steel wire 21 and steel wire 25 respectively.

[0039] The control assembly includes a control motor 18 fixed inside the control box 3, and a rotating shaft 19 rotatably mounted inside the control box 3. The control motor 18 drives the rotating shaft 19 via a belt structure. Control cylinders 20 are fixed to both ends of the rotating shaft 19. A steel wire 21 is spirally wound around the control cylinder 20, with the middle section of the steel wire 21 wound around the control cylinder 20. Both ends are connected to the slide 11 of one of the cleaning mechanisms. A rotating shaft 22 is rotatably mounted inside the control box 3 and outside the two control cylinders 20. A gear 23 is fixed to the rotating shaft 22. A gear 26 is fixed to the end of the control cylinder 20, and the gear 26 meshes with the gear 23. Control cylinders 24 are fixed to both ends of the rotating shaft 22. A steel wire 25 is wound around the control cylinder 24, and its free end is connected to the slide 11 of another cleaning mechanism. When the rotating shaft 19 is driven to rotate forward and backward, it alternately controls the movement of each cleaning mechanism.

[0040] Operating principle: The detection module 4 detects the external climate environment, such as wind, sand, rain, etc. The detection signal is fed back to the control module 12. The control module 12 analyzes the signal data and issues protection commands. Specifically, the winding motor 14 drives the winding drum 15 to rotate, controlling the winding and unwinding of the shielding layer 7. Under the gravity of the counterweight cylinder 8, the shielding layer 7 unfolds downward and shields each side of the cabinet 1. The shielding layer 7 on each side can be controlled individually according to the climate environment detection data. For example, if the wind direction is towards one side of the cabinet, the shielding layer 7 on that side can be controlled to descend and shield, preventing sand and dust and other impurities from adhering to the cabinet 1. When the counterweight cylinder 8 descends to the height of the magnetic block 2, the magnetic block 2 can magnetically attract the counterweight cylinder 8, so that the shielding layer 7 is spread on the side of the cabinet 1 and prevents the counterweight cylinder 8 from shaking and hitting the cabinet 1.

[0041] When the shielding layer 7 changes from an unfolded to a retracted state, the surface of the shielding layer 7 can be cleaned by the cleaning mechanism, that is, the impurities attached to the surface of the shielding layer 7 can be removed. Specifically, by controlling the motor 18 to drive the rotating shaft 19 to rotate forward and backward, the rotating shaft 19 can be driven to rotate forward and backward synchronously. The steel wire 21 is wound around the control cylinder 20 in a spiral manner. At this time, the set of cleaning mechanisms connected to the steel wire 21 moves alternately. That is, in this set of cleaning mechanisms, one scraper 10 moves inward, while the other scraper 10 moves inward under the action of the spring 17. When the target side of the shielding layer 7 needs to be rolled up, the slide 11 and scraper 10 on that side move inward, so that the scraper 10 contacts the surface of the shielding layer 7 to achieve the scraping operation. Furthermore, when the rotating shaft 19 rotates in both directions, the rotating shaft 22 also rotates in both directions under the gear transmission, and another set of cleaning mechanisms also moves alternately. That is, in this set of cleaning mechanisms, one scraper 10 moves inward, and the other scraper 10 resets outward. Combined with the individual control of each hoisting shielding mechanism, the rolled-up shielding layer 7 can be cleaned accordingly.

[0042] Furthermore, the shielding layer 7 can not only be used for shielding and protection, but also for cleaning and cooling the cabinet 1. Specifically, the water collection tank 5 can collect natural rainwater, and the filter plate 6 can filter out large-sized garbage and impurities. When the winding motor 14 receives the signal that the internal temperature of the cabinet 1 has reached a threshold and auxiliary cooling is required, the shielding layer 7 is controlled by winding and unwinding. The transfer pump 501 transmits water through a pipe to the connecting box 16, which is connected to the winding drum 15. Finally, the water is transmitted from the winding drum 15 to the water pipe 9, and then released from the atomizing nozzle 801 on the counterweight cylinder 8. The atomizing nozzle 801 sprays the water atomized onto the side of the cabinet 1 to achieve the purpose of auxiliary cooling. It should be noted that this part is for auxiliary cooling. Outdoors, it mainly collects outdoor rainwater. A water level monitor can be installed inside the water collection tank 5. Auxiliary cooling can only be activated when there is a sufficient amount of water.

[0043] When the shielding layer 7 is in the winding state, the counterweight cylinder 8 is clamped in the position of the winding slot 301, and the counterweight cylinder 8 is fixed by the electromagnetic sliding shaft 303 cooperating with the fixing hole 802.

[0044] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
