Description

Technical Field

[0001] This invention relates to the technical field of intelligent metering boxes, and more particularly to intelligent metering boxes suitable for extreme wind and sand environments. Background Technology

[0002] In deserts, Gobi, grasslands, and areas with high industrial dust, outdoor smart metering boxes are exposed to extreme environments with high wind speeds and high sand content for extended periods. Wind and sand not only wear down the box's surface but also penetrate the interior through ventilation openings, accumulating on the terminals, current transformers, electricity meters, and communication modules. This leads to increased contact resistance, decreased insulation performance, signal interference, and even short-circuit faults, severely impacting metering accuracy and equipment reliability.

[0003] Currently, most metering boxes use fixed louvers or perforated plates as their heat dissipation structure, with a constant opening that cannot be dynamically adjusted according to the intensity of wind and sand. During sandstorms, large amounts of sand and dust enter the box directly with the airflow, causing internal contamination. While some solutions aim to prevent dust by adding filters or increasing the sealing level, fixed filters are easily clogged by sand and dust, leading to ventilation failure and excessively high internal temperatures. A fully enclosed design, while isolating sand and dust, sacrifices necessary heat dissipation capacity, similarly threatening the lifespan of electronic components.

[0004] Existing technologies generally lack an adaptive response mechanism to wind and sand intensity, and cannot achieve a dynamic balance of "sufficient heat dissipation when wind and sand are weak and active flow restriction or closure when wind and sand are strong", resulting in protection and heat dissipation always being in conflict.

[0005] Therefore, there is an urgent need for an intelligent metering box suitable for extreme wind and sand environments, which can balance heat dissipation requirements and sand protection reliability, and ensure the long-term stable operation of power metering equipment in extreme wind and sand environments. Summary of the Invention

[0006] In order to overcome the shortcomings of existing technologies that generally lack an adaptive response mechanism to wind and sand intensity, and cannot achieve a dynamic balance of "sufficient heat dissipation when wind and sand are weak and active flow restriction or closure when wind and sand are strong", resulting in protection and heat dissipation always being in opposition, this invention provides an intelligent metering box suitable for extreme wind and sand environments.

[0007] A smart metering box suitable for extreme wind and sand environments includes a cabinet. One side of the cabinet has doors symmetrically distributed along its sides. A fixed frame symmetrically distributed along its sides is also located on one side of the cabinet. Equally spaced air guide plates are rotatably connected to the fixed frame along its longitudinal direction. Connecting rods symmetrically distributed along the air guide plates are rotatably connected between the air guide plates on the same side. A fixed rail is fixedly connected to the fixed frame. A sliding net is slidably connected to the fixed rail. Swinging rods symmetrically distributed along the sliding net are fixedly connected to the sliding net. The swinging rods are rotatably connected to one of the air guide plates. A wind speed sensor is fixedly connected to the fixed frame. Electromagnets symmetrically distributed along the fixed frame are fixedly connected to the fixed frame. The electromagnets and the wind speed sensor are electrically connected via a control module. When energized, the electromagnets attract the sliding net. At least one first telescopic rod is fixedly connected between the sliding net and the fixed frame on the same side.

[0008] Optionally, a guide frame is fixedly connected to the lower part of the fixed frame, and the guide frame is slidably connected to the sliding net on the same side.

[0009] Optionally, the fixed frame is provided with an opening and closing plate on the side near the guide frame, and a storage cavity is provided between the fixed frame, the opening and closing plate and the guide frame on the same side, the storage cavity being used to store collected sand and gravel.

[0010] Optionally, the opening and closing plate is rotatably connected to the fixed frame on the same side, and a magnet for attracting the opening and closing plate is fixed to the fixed frame.

[0011] Optionally, the guide frame has a downward inclined surface on the side facing the opening and closing plate, for guiding sand and gravel downwards to the opening and closing plate.

[0012] Optionally, the tilt angle of the guide frame is set to 10° to 30°.

[0013] Optionally, the sliding net has a strip-shaped discharge port on the side near the guide frame.

[0014] Optionally, a cleaning plate is slidably connected to the sliding net, and guide rods symmetrically distributed along the cleaning plate are fixedly connected to the cleaning plate. Guide grooves symmetrically distributed along the fixed frame are opened on the fixed frame, and the guide rods are slidably connected to the adjacent guide grooves.

[0015] Optionally, at least one second telescopic rod is fixedly connected between the cleaning plate and the sliding net on the same side.

[0016] The beneficial effects are: This invention utilizes wind pressure to directly drive the sliding net and the wind guide plate to work together, and can automatically balance between "more heat dissipation" and "less sand ingress" without the need for external energy, so as to achieve adaptive dynamic adjustment of wind and sand intensity and break through the static limitations of traditional fixed louvers.

[0017] By combining a wind speed sensor with an electromagnet, the wind deflector can be instantly closed under extreme conditions such as sandstorms, providing the highest level of protection and consuming power only when necessary, making it energy-efficient and highly effective.

[0018] Utilizing a guide ramp and magnetically operated opening and closing plate structure, the system achieves automatic sand and gravel collection and full-load self-discharge, eliminating the need for manual sand cleaning and making it particularly suitable for remote, unattended areas. Furthermore, the cleaning plate automatically scrapes away accumulated dust from the filter screen as the sliding mesh reciprocates, preventing blockages that could lead to heat dissipation deterioration or pressure differential damage, thus extending equipment maintenance cycles.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0028] Example 1: This invention relates to an intelligent metering box with wind and sand protection capabilities, particularly suitable for outdoor power metering scenarios with frequent and drastically varying sandstorms, such as deserts, Gobi, grasslands, and industrial dust areas. This metering box integrates a mechanically linked adaptive airflow structure, an electromagnetic emergency interlocking system, an automatic sand and dust collection and discharge mechanism, and a self-cleaning device. Without requiring a continuous external power supply, it achieves dynamic response and active protection against sandstorm intrusion, while simultaneously meeting the high-efficiency heat dissipation requirements under normal operating conditions. This fundamentally solves the technical contradiction of traditional metering boxes where "heat dissipation and dust prevention are mutually exclusive" in windy and sandy environments.

[0029] like Figures 1 to 3 As shown, the intelligent metering box mainly includes a chassis 101, a door 102, a fixed frame 103, air guide plates 104, a connecting rod 105, a fixed rail 106, a sliding net 107, a swing rod 108, a wind speed sensor 109, an electromagnet 110, a first telescopic rod 111, and a control module, among other core components. The chassis 101 is a high-strength, corrosion-resistant metal shell, with two symmetrical doors 102 on its front side for easy meter reading and equipment maintenance. Fixed frames 103 are symmetrically installed on the left and right sides of the chassis 101, serving as the mounting base for the ventilation and protection system. Ten equally spaced air guide plates 104 are rotatably connected to the fixed frame 103 along its longitudinal direction. These air guide plates 104 are arranged in a louvered manner, opening horizontally upwards under normal conditions to form a ventilation channel. Adjacent air guide plates 104 are hinged to each other by connecting rods 105 symmetrically distributed along their front and rear sides, so that the swing of any air guide plate 104 can drive the other air guide plates 104 in a synchronous manner through the linkage mechanism, so as to achieve the consistency of the overall opening and closing action.

[0030] A fixed rail 106 is fixedly connected to the inner side of the fixed frame 103, and a sliding mesh 107 is slidably connected to the fixed rail 106 in the left-right direction. The sliding mesh 107 is woven from high-density stainless steel wire, and the aperture is optimized by hydrodynamics to effectively intercept sand and dust particles while ensuring airflow with low wind resistance. Swing rods 108 are symmetrically fixed to the front and rear sides of the sliding mesh 107, and the right end of each swing rod 108 is rotatably connected to the second air guide plate 104 on the lower side. When the sliding mesh 107 moves inward or outward under the action of external force, the swing rods 108 can pull or push the corresponding air guide plate 104 to swing around its axis, thereby driving the entire row of air guide plates 104 to adjust their opening synchronously through the connecting rod 105.

[0031] To achieve an adaptive response to sandstorm intensity, two first telescopic rods 111 (such as springs or gas springs) are fixedly connected between the sliding net 107 and the fixed frame 103 on the same side. In normal windless or lightly windy conditions, the first telescopic rods 111 are in a naturally extended state, pushing the sliding net 107 outwards, keeping the air guide plate 104 at its maximum opening, ensuring sufficient convective heat dissipation for the internal components of the chassis 101. When the external sandstorm gradually intensifies, the high-speed airflow carrying sand particles impacts the sliding net 107, generating an inward thrust that compresses the first telescopic rods 111, causing the sliding net 107 to slide inwards. The sliding net 107, through the swing rod 108, pulls the air guide plate 104 downwards, reducing the gaps between the air guide plates 104 and automatically decreasing the air intake, thereby reducing the amount of sand intrusion. This forms an adaptive response mechanism to sandstorm intensity: achieving a dynamic balance of "less air intake during strong sandstorms and more heat dissipation during weak sandstorms." This process is entirely driven by wind pressure, requiring no external energy, forming a passive adaptive adjustment mechanism.

[0032] To further enhance protection against extreme sandstorms, a wind speed sensor 109 is installed on the fixed frame 103. Electromagnets 110, symmetrically distributed along the front and back of the fixed frame 103, are also fixed to the frame. The electromagnets 110 and the wind speed sensor 109 are electrically connected via a control module. The wind speed sensor 109 monitors the ambient wind speed in real time and transmits the signal to the control module. When the wind speed reaches a preset threshold (e.g., 15 m / s, corresponding to a sandstorm level), the control module immediately energizes the electromagnets 110, generating a strong magnetic force that instantly attracts the sliding net 107, causing it to move rapidly inward to its extreme position. At this time, the first telescopic rod 111 is completely compressed, and the wind guide plate 104 is completely closed under the linkage of the swing rod 108 and the connecting rod 105, forming a sealed barrier that completely blocks the path of sand and dust. This electromagnetic interlocking mechanism, as an "emergency protection mode," is only activated when the sand and dust intensity exceeds the adaptive adjustment range. It has extremely low power consumption and is suitable for applications in remote areas powered by solar energy or batteries.

[0033] Example 2: Based on Example 1, as follows Figures 4 to 5As shown, during long-term operation, the sand and dust intercepted by the sliding net 107 need to be effectively treated to avoid accumulation and blockage. To this end, a guide frame 201 is fixedly connected to the lower part of the fixed frame 103. The guide frame 201 slides in conjunction with the sliding net 107, and its top side is provided with an inclined surface that slopes downwards towards the opening and closing plate 202. The preferred inclination angle is 30° to facilitate the natural sliding of sand and gravel under gravity. A rotatable opening and closing plate 202 is provided on the fixed frame 103 near the guide frame 201. The guide frame 201, the opening and closing plate 202, and the fixed frame 103 on the same side enclose a storage cavity 2021 for temporary storage of collected sand and gravel. A magnet 203 is also fixedly connected to the fixed frame 103, which normally attracts the opening and closing plate 202, keeping it closed and preventing sand and dust from spilling out. The sliding mesh 107 has a strip-shaped discharge port 204 on the side near the guide frame 201. The sand and gravel filtered by the sliding mesh 107 fall downward into the storage cavity 2021. Some of the small sand and gravel that pass through the sliding mesh 107 also fall downward into the storage cavity 2021 through the discharge port 204. When the sand and gravel in the storage cavity 2021 accumulate to a certain weight, their own gravity overcomes the magnetic attraction and pushes the opening and closing plate 202 outward, and the sand and gravel are automatically discharged. After the wind and sand weaken, the opening and closing plate 202 automatically resets under the action of the magnet 203, realizing the automatic collection of sand and dust and gravity-triggered discharge without manual intervention.

[0034] Example 3: Based on Example 2, such as Figures 6 to 7 As shown, the sliding net 107 also integrates a self-cleaning mechanism: a cleaning plate 301 is slidably connected to the sliding net 107 in the vertical direction, and guide rods 302 symmetrically distributed along the front and back of the cleaning plate 301 are fixed to the cleaning plate 301. A guide groove 303 is correspondingly provided on the fixed frame 103, and the guide rods 302 slide in cooperation with the adjacent guide grooves 303. Two second telescopic rods 304 (such as small springs) are also provided between the cleaning plate 301 and the sliding net 107. When the sliding net 107 moves inward due to wind and sand, it drives the cleaning plate 301 to move inward synchronously. Simultaneously, under the oblique constraint of the guide grooves 303, the guide rods 302 force the cleaning plate 301 to move downward relative to the sliding net 107, compressing the second telescopic rods 304. When the wind and sand weaken and the first telescopic rod 111 pushes the sliding net 107 outward to reset, the second telescopic rods 304 rebound, cooperating with the guide grooves 303 to guide, causing the cleaning plate 301 to scrape upward relative to the sliding net 107. The cleaning plate 301, through this repeated motion, automatically removes fine sand and dust adhering to the surface of the sliding mesh 107, like a "scraper," preventing the filter from clogging easily and ensuring long-term ventilation efficiency.

[0035] In summary, this invention achieves a unified system of heat dissipation, sand prevention, self-maintenance, and intelligent response within a single structure through a four-pronged collaborative mechanism: adaptive wind pressure regulation, electromagnetic emergency interlocking, automatic sand and dust collection and discharge, and self-cleaning of the sliding mesh 107. Users require no additional operation; the metering box automatically switches its operating mode according to the intensity of wind and sand: sufficient heat dissipation in light winds, moderate current limiting in moderate winds, and complete sealing in strong winds and sandstorms. It also automatically cleans and discharges dust and sand afterward, truly meeting the long-term, maintenance-free, and highly reliable operation requirements of power metering equipment in extreme wind and sand environments.
