Description

Technical Field

[0001] This application relates to the technical field of ring main units, and in particular to a digital integrated primary and secondary ring main unit. Background Technology

[0002] Digital integrated primary and secondary ring main units are a new type of power equipment that integrates primary equipment (high-voltage section) and secondary equipment (low-voltage control and monitoring section). These units feature modular design, intelligent control, and high energy efficiency, and are widely used in power distribution system automation scenarios.

[0003] One type of primary and secondary integrated ring network box in the related technology includes a box body, a receiving groove on one side of the box body, and a box door rotatably connected to the box body for closing the receiving groove.

[0004] When ring main units are used in desert photovoltaic bases, under the long-term action of strong winds and shifting sands, the soft sand in front of the ring main unit accumulates continuously under the action of wind, burying the lower edge of the front door with fine sand. The gaps between the bottom of the door and the bottom edge of the box are filled with sand particles, forming a high-density sand wedge. This results in the opening angle of the box door being limited or even impossible to open, affecting the maintenance personnel's ability to carry out maintenance. Summary of the Invention

[0005] To address the problem of difficulty in opening the enclosure door due to fine sand accumulation, this application provides a digital primary and secondary integrated ring network enclosure.

[0006] This application provides a digital integrated primary and secondary ring network box, which adopts the following technical solution: A digital primary and secondary fusion integrated ring network box includes a box body. A storage slot is formed on one side of the box body along its width. A door for closing the storage slot is rotatably connected to the side wall of the box body. A sealing frame arranged circumferentially within the storage slot is provided. When the door is closed, it seals against the sealing frame. A base is provided below the box body. A receiving slot is provided on the side of the base facing the box body. A sand-cleaning mechanism is provided on the base. A groove is formed on the side of the box body where the storage slot is located. The groove is located below the storage slot and extends vertically through the box body. The sand-cleaning mechanism includes an operating plate located on the side of the base facing the door and a... The vibration assembly within the receiving slot has an operating plate located directly below the lower edge of the box door on the side closest to the box body, at least covering the projected area of ​​the box door. The height of the operating plate gradually decreases away from the box body. A sand-unloading gap is left between the lower surface of the operating plate and the ground. Several elastic elements are provided between the operating plate and the base, and these elastic elements apply a force to the operating plate to move it towards the base. The elastic elements allow the operating plate to be suspended relative to the base and not bear the weight of the box body. The vibration assembly is used to drive the operating plate to vibrate under the elastic restoring action of the elastic elements, thereby shaking off the sand accumulated on the operating plate and causing the sand to slide away from the box body.

[0007] By adopting the above technical solution, the door seals against the sealing frame when closed, which improves the dustproof and waterproof performance of the storage slot and prevents sand and dust from entering the box. The vibration component drives the operating plate to reciprocate in a direction away from the box, which causes the elastic element to drive the operating plate to return to its original position. The two achieve periodic vibration of the operating plate relative to the base, which causes the sand and dust accumulated in front of the door to slide away from the box. This effectively avoids the problem of sand and soil accumulating at the bottom edge of the door and at the door seams, which can lead to obstruction of opening and failure of sealing. It significantly reduces the frequency of manual sand removal for the ring network box in sandy environments such as desert photovoltaic, and improves the accessibility of the equipment for operation and maintenance and the long-term reliability of operation under sand burial conditions.

[0008] Optionally, the operating panel is provided with two baffles spaced apart along the length of the operating panel on the side facing the base, the elastic element is located between the two baffles, and the side of the baffle facing the base is provided with an elastic layer; when the vibration assembly is not activated, the baffle abuts against the side of the base facing the box door.

[0009] By adopting the above technical solution, when the vibration component is not activated, the baffle and the base abut against the side facing the box door, which can initially limit the operation plate, making the reciprocating stroke and amplitude of the operation plate more stable and controllable during vibration, and serving as a support reference for the operation plate relative to the base. Adding an elastic layer to the abutment part between the baffle and the base reduces the hard collision between the base and the baffle, while reducing noise and structural impact, and extending the service life of the elastic components and related connecting parts. In addition, the cooperation between the baffle and the base constrains the movement direction of the operation plate relative to the base, ensuring that the operation plate mainly vibrates along the designed tilt direction, which is conducive to the effective transfer of vibration energy to the accumulated sand and soil, improving the reliability and efficiency of the sand removal process.

[0010] Optionally, the base has a receiving hole on the end face facing the operation panel that communicates with the receiving groove. The vibration assembly includes a vibration motor disposed on the bottom wall of the receiving groove and a push rod passing through the receiving hole. The output shaft of the vibration motor is sleeved with a cam located at the end of the push rod away from the operation panel. The circumferential surface of the cam abuts against the end of the push rod away from the operation panel. The end of the push rod near the operation panel is fixedly connected to the operation panel.

[0011] By adopting the above technical solution, on the one hand, the rotational motion of the motor is reliably converted into the reciprocating pushing motion of the push rod along the direction of the receiving hole by the abutting cooperation between the cam on the output shaft of the vibratory motor and the end of the push rod away from the operating plate. This motion is then transmitted to the operating plate through the push rod, so that the operating plate obtains periodic vibration with a clear rhythm and controllable amplitude, thereby improving the vibration's efficiency in disturbing accumulated sand and dust. On the other hand, the vibratory motor and cam are arranged in a sealed receiving groove in the base, and the push rod is only connected to the outside through the receiving hole. This effectively isolates the motor and cam mechanism from sand and water vapor while ensuring the transmission of thrust, reducing abrasive wear and corrosion of the vibration components in the sandy environment, and extending the service life of the vibration components. Thus, under the premise of simple structure, stable and durable mechanical drive of the operating plate is achieved, improving the reliability and applicability of the entire sand-clearing mechanism.

[0012] Optionally, the push rod is fitted with a retractable folding tube, one end of which is fixedly connected to the operating plate, and the other end of which is fixedly connected to the side of the base facing the operating plate.

[0013] By adopting the above technical solution, the folding tube connects the operating plate to the base, forming a sealed space between the operating plate and the base. This ensures that the gap between the push rod and the receiving hole is within the sealed space, effectively preventing external wind, sand, dust, and rainwater from entering the base receiving groove and the space where the vibration component is located along the push rod channel. This avoids problems such as push rod jamming, cam and bearing wear, and motor moisture damage caused by sand particles entering the system, reducing the failure rate and maintenance frequency of the vibration mechanism, and significantly improving the sealing reliability and long-term stable working capability of the sand-clearing mechanism in harsh environments such as desert sandstorms.

[0014] Optionally, the inner wall of the storage slot along the length of the box is a fixed surface, a fixed groove is provided on the fixed surface, a vent hole is provided on the bottom wall of the fixed groove, and a filter screen is provided in the fixed groove.

[0015] By adopting the above technical solution, when the box door is closed, the air vents can achieve gas exchange or pressure equalization between the inside of the box and the outside, avoiding the formation of a large pressure difference between the inside and outside of the storage tank due to temperature changes or wind pressure, which would affect the sealing of the box door. The filter screen intercepts and filters the airflow passing through the air vents, blocking the sand and dust and particles carried by the filter screen to one side of the storage tank, preventing sand and dust from directly entering the box through the air vents. Thus, without significantly reducing the overall sealing and protection level of the box, the ventilation, pressure reduction and sand prevention needs of the local area are taken into account, improving the sealing reliability and long-term operational stability of the ring network box in the desert sandstorm environment.

[0016] Optionally, the housing is provided with a cleaning mechanism for cleaning the filter screen. The cleaning mechanism includes a slide bar that is horizontally slidably disposed on a fixed surface. The slide bar is located on the side of the filter screen away from the vent hole. The side of the slide bar facing the vent hole is provided with bristles for cleaning the filter screen. A discharge hole is provided on the side of the housing along the length direction, connecting the bottom of the fixed groove to the outside of the housing. The upper opening of the discharge hole is located on the side of the filter screen facing the vent hole. A linkage component is provided in the base for linking the push rod and the slide bar. The linkage component is used to convert the reciprocating motion of the push rod into the reciprocating sliding of the slide bar along the width direction of the housing, so as to drive the bristles to reciprocately brush the back surface of the filter screen.

[0017] By adopting the above technical solution, the push rod and the slide bar are linked by a linkage component, converting the reciprocating motion of the push rod into the reciprocating sliding motion of the slide bar. Whenever the vibration component works, causing the push rod to reciprocate, the bristles automatically and periodically brush the back surface of the filter screen in front of it, effectively removing the sand and dust attached to the filter screen and preventing the filter screen from becoming clogged due to long-term sand accumulation, which would reduce the ventilation capacity of the vents. The sand and dust brushed off by the bristles can be discharged from the bottom of the fixed groove through the discharge hole to the outside of the box, preventing the sand and dust from accumulating again in the fixed groove. This achieves self-cleaning of the filter screen and orderly discharge of accumulated sand, thereby improving the long-term stability and maintenance-free capability of the sand cleaning mechanism and the ventilated structure in the desert sandy environment.

[0018] Optionally, the lower inner wall of the storage slot is provided with a mounting hole that communicates with the receiving slot. The linkage includes a single-arm lever that passes through the mounting hole. The single-arm lever is rotatably connected to the inner wall of the receiving slot along the length direction of the base. The single-arm lever has a first sliding hole and a second sliding hole in the shape of an elongated hole on the side facing the filter screen. A first sliding rod is slidably connected in the first sliding hole, and a second sliding rod is slidably connected in the second sliding hole. One end of the first sliding rod is connected to a push rod, and one end of the second sliding rod is connected to a slide bar.

[0019] By adopting the above technical solution, the reciprocating linear motion of the push rod is transmitted to the single-arm lever via the first slide rod, causing the single-arm lever to swing. The single-arm lever drives the second slide rod to reciprocate along the width of the housing, thereby driving the bristles on the slide rod to mechanically brush and clean the back of the filter screen. This achieves cross-cavity and cross-height motion transmission between the vibration component in the base and the cleaning mechanism in the housing. The elongated hole-shaped slide rod cooperates with the slide rod, providing a certain degree of adaptive adjustment capability for the installation position deviation and stroke difference between the push rod and the slide rod, avoiding jamming and overload caused by rigid rod system, and further improving the stability and durability of the cleaning mechanism under long-term vibration conditions.

[0020] Optionally, the lower end face of the housing is provided with an energy storage module for electrical connection with the vibration component, and the top of the housing is provided with a solar panel for electrical connection with the energy storage module.

[0021] By adopting the above technical solution, the abundant sunshine at the desert photovoltaic power station site enables the solar panels to convert solar energy into electrical energy, continuously replenishing the energy storage module. Without relying on the secondary power supply inside the ring network box or an external power supply, it provides stable, low-power operating power for the vibration motor, achieving a green and energy-saving effect. In addition, it enables the vibration component to have an independent energy supply, improving the self-sufficiency and reliability of the sand-clearing mechanism in remote, unattended desert environments, and ensuring that the ring network box has a long-term automatic sand-proof maintenance function.

[0022] Optionally, the upper inner wall of the groove is provided with a receiving groove, and a distance measuring sensor for detecting the distance between the ground in front of the box and the lower edge of the box door is provided in the receiving groove. A controller electrically connected to the distance measuring sensor is provided in the receiving groove. The controller is electrically connected to the vibration component and is used to control the start and stop of the vibration component according to the detection result of the distance measuring sensor.

[0023] By adopting the above technical solution, the distance change from the bottom edge of the box door to the ground in front can be detected in real time by the distance sensor, thereby reflecting the height of sand accumulation in the area. Moreover, the distance sensor is located in the receiving tank, reducing the risk of it being directly impacted by wind and sand. The controller automatically controls the start and stop of the vibration component based on the distance measurement results, so that the sand cleaning mechanism only starts working when it detects that the sand accumulation in front of the door reaches or exceeds the preset threshold. This avoids unnecessary energy consumption and mechanical wear caused by frequent vibration when the sand accumulation is small, and can trigger sand cleaning in time when the sand accumulation is severe, improving the targeting and effectiveness of the sand cleaning action, realizing intelligent control of the vibration component, and improving the automation level of the entire sand cleaning system.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. When the box door is closed, it seals against the sealing frame, which can improve the dustproof and waterproof performance of the storage slot and prevent sand and dust from entering the box. The vibration component drives the operating plate to reciprocate in the direction away from the box, so that the elastic element drives the operating plate to return to its original position. The two achieve periodic vibration of the operating plate relative to the base, which causes the sand and dust accumulated in front of the box door to slide away from the box. This effectively avoids the problem of sand and soil accumulating at the bottom edge of the box door and the door gap, which can obstruct the opening of the door. It significantly reduces the frequency of manual sand removal for the ring network box in sandy environments such as desert photovoltaic, and improves the accessibility of the equipment for operation and maintenance and the long-term reliability of operation under sand burial conditions. 2. The filter screen has a self-cleaning structure consisting of a filter screen, sliding strips, brush bristles and discharge holes, which cleans and orderly discharges the accumulated sand on the filter screen. The cross-cavity linkage mechanism consisting of a single-arm lever, a first sliding rod and a second sliding rod can automatically remove sand from the air passage during the sand cleaning process.

[0027] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0028] This embodiment discloses a digital primary and secondary integrated ring network box. (Refer to...) Figure 1 A digital primary and secondary integrated ring network box includes a box body 1, a base 2, and a box door 3.

[0029] Reference Figure 1 and Figure 2 The box body 1 is fixedly connected to the base 2. A storage slot 11 and a recess 12 are provided on one side of the box body 1 along its width. A sealing frame 16, arranged circumferentially along the storage slot 11, is fixedly connected inside the storage slot 11. The recess 12 is located directly below the storage slot 11, extending through the box body 1 along its length and vertically, thus communicating with the storage slot 11.

[0030] Reference Figure 1 and Figure 2 There are two doors 3, which are symmetrical to each other. The doors 3 are located in the storage slot 11, and the box body 1 and the doors 3 are connected by hinges. When the doors 3 are closed, they are sealed and abut against the sealing frame 16.

[0031] Reference Figure 2 and Figure 3 The storage slot 11 has two inner walls along the length of the box 1, both of which are fixed surfaces 111. Each fixed surface 111 has a fixed groove 13, and the bottom wall of the fixed groove 13 has several ventilation holes 131. A filter screen 132 is installed in the ventilation hole 131, and the filter screen 132 is fixedly connected to the inner wall of the fixed groove 13.

[0032] Reference Figure 1 and Figure 2The lower inner wall of the vent 131 is provided with a discharge hole 14, which extends away from the storage tank 11. The upper opening of the discharge hole 14 is located on the side of the filter screen 132 facing the vent 131.

[0033] Reference Figure 2 and Figure 3 The housing 1 contains two cleaning mechanisms 4, each cleaning mechanism 4 cleaning one filter screen 132. Each cleaning mechanism 4 includes a slide bar 41, a slider 42, and bristles 43. Two grooves 15, each dovetail-shaped, are formed on the fixed surface 111. The grooves 15 extend along the width of the housing 1.

[0034] Reference Figure 2 and Figure 4 The slider 41 is vertically arranged. Two sliders 42 are provided, and both sliders 42 are fixedly connected to the end face of the slider 41 facing the fixed groove 13. The sliders 42 are dovetail-shaped. Each slider 42 is slidably arranged in a groove 15.

[0035] Reference Figure 2 The brush bristles 43 are fixedly connected to the end face of the slide bar 41 facing the filter screen 132. The brush bristles 43 move along the width direction of the housing 1 under the action of the slide bar 41, and can brush the back surface of the filter screen 132.

[0036] Reference Figure 2 and Figure 4 One end face of the base 2 is coplanar with the bottom wall of the groove 12. The end face of the base 2 facing the housing 1 is provided with a receiving groove 21.

[0037] Reference Figure 4 and Figure 5 Two sand-clearing mechanisms 5 are installed on the base 2, and the two sand-clearing mechanisms 5 are symmetrically distributed along the vertical central axis of the base 2. The sand-clearing mechanisms 5 are used to clean and push away the sand accumulated in front of the box door 3, so that the sand no longer affects the opening of the box door 3. The sand-clearing mechanism 5 includes a vibration component 51, an operating plate 52, and an elastic element 53.

[0038] Reference Figure 1 , Figure 2 and Figure 4 The control panel 52 is located on the side of the base 2 facing the door 3, with its upper end inserted into the groove 12. The control panel 52 is tilted, and its height gradually decreases away from the box body 1. The control panel 52 is located directly below the lower edge of the door 3 and at least covers the projected area of ​​the door 3. A sand-unloading gap is left between the lower surface of the control panel 52 and the ground.

[0039] Reference Figure 3 and Figure 5Two baffles 54 are fixedly connected to the end face of the operating plate 52 facing the base 2, and the two baffles 54 are arranged at intervals along the length of the operating plate 52. The end faces of the two baffles 54 that are far apart from each other are coplanar with the end face of the operating plate 52. An elastic layer 55 is fixedly connected to the end face of the baffles 54 facing the base 2. When the vibration assembly 51 is not activated and the operating plate 52 is in a stationary state, the operating plate 52 tends to move towards the base 2 under the action of the elastic element 53, so that the operating plate 52 abuts against the bottom wall of the groove 12, and the baffles 54 abut against the end face of the base 2 facing the door 3 through the elastic layer 55, thereby limiting the initial position and vibration stroke of the operating plate 52.

[0040] Reference Figure 3 and Figure 5 Two elastic elements 53 are provided, distributed along the length of the operating plate 52. Both elastic elements 53 are located between the two baffles 54. Each elastic element 53 is a spring 531, with one end fixedly connected to the base 2 and the other end fixedly connected to the operating plate 52. The spring 531 is in a compressed state. The elastic elements 53 allow the operating plate 52 to be suspended relative to the base 2 and do not bear the weight of the housing 1. In other embodiments, one, three, or other quantities of elastic elements 53 may be provided.

[0041] Reference Figure 3 and Figure 5 Each spring 531 is fitted with a folding tube 56, which is retractable. One end of the folding tube 56 is fixedly connected to the operating plate 52, and the other end of the folding tube 56 is fixedly connected to the side of the base 2 facing the operating plate 52. The operating plate 52, the folding tube 56, and the base 2 together form a sealed space.

[0042] Reference Figure 3 and Figure 5 The base 2 has two receiving holes 22 on its end face facing the door 3, and both receiving holes 22 are connected to the receiving groove 21. The two receiving holes 22 are distributed along the length of the base 2. The side of each receiving hole 22 away from the receiving groove 21 is connected to a sealed space, thereby preventing external wind, sand, dust and rainwater from entering the receiving groove 21 through the push rod 513 channel.

[0043] Reference Figure 4 and Figure 5 The vibration assembly 51 is disposed within the receiving groove 21. The vibration assembly 51 includes a vibration motor 511, a cam 512, and a push rod 513. The push rod 513 passes through the receiving hole 22. One end of the push rod 513 is inserted into the receiving groove 21; the other end of the push rod 513 is inserted into the sealed space and is fixedly connected to the operating plate 52. The spring 531 and the folding tube 56 are both sleeved on the outside of the push rod 513. The folding tube 56 can extend and retract accordingly with the reciprocating movement of the push rod 513 along the direction of the receiving hole 22.

[0044] Reference Figure 4 and Figure 5 The vibration motor 511 is fixedly connected to the bottom wall of the receiving groove 21. The cam 512 is sleeved on the output shaft of the vibration motor 511.

[0045] Reference Figure 2 and Figure 4 An energy storage module is fixedly connected to the lower end face of the housing 1, and the energy storage module is electrically connected to the vibration motor 511. A mounting hole 17 is provided on the lower end face of the housing 1, and the mounting hole 17 communicates with the receiving groove 21.

[0046] Reference Figure 1 and Figure 2 A solar panel 18 is fixedly connected to the upper surface of the housing 1, and the solar panel 18 is electrically connected to the energy storage module. The solar panel 18 converts solar energy into electrical energy and supplies power to the energy storage module.

[0047] Reference Figure 3 and Figure 4 The base 2 is equipped with a linkage 6, which is used to convert the reciprocating motion of the push rod 513 into the reciprocating sliding of the slide bar 41 along the width direction of the housing 1, so as to drive the brush to reciprocate to brush the back surface of the filter screen 132.

[0048] Reference Figure 3 and Figure 4 The linkage 6 includes a single-arm lever 61, a round rod 62, a first slide rod 63, and a second slide rod 64. The round rod 62 is fixedly connected to the inner wall of the receiving groove 21 along the length direction of the base 2, and the round rod 62 is located below the push rod 513.

[0049] Reference Figure 3 and Figure 4 A single-arm lever 61 is fitted over the round rod 62. The single-arm lever 61 extends upward through the mounting hole 17 and is inserted into the storage slot 11. The end face of the single-arm lever 61 facing the push rod 513 has a first sliding hole 611 and a second sliding hole 612, with the first sliding hole 611 located on the side of the second sliding hole 612 closer to the round rod 62. Both the first sliding hole 611 and the second sliding hole 612 are elongated holes, and the length direction of the first sliding hole 611 and the length direction of the second sliding hole 612 are consistent with the length direction of the single-arm lever 61.

[0050] Reference Figure 3 and Figure 4 The first slide rod 63 is slidably disposed within the first slide hole 611, and one end of the first slide rod 63 is fixedly connected to the push rod 513. The second slide rod 64 is slidably disposed within the second slide hole 612, and one end of the second slide rod 64 is fixedly connected to the slide bar 41.

[0051] Reference Figure 1 and Figure 2The upper inner wall of the groove 12 has a receiving slot, and the groove 12 is located on the horizontal side of the receiving slot 21. The opening of the groove 12 faces the ground in front of the housing 1, and the opening of the groove 12 is not blocked by the operating panel 52. A ranging sensor is fixedly installed on the bottom wall of the receiving slot. The detection surface of the ranging sensor faces the ground in front of the housing 1, and its transmission / reception direction is basically vertical downward or slightly tilted relative to the vertical direction towards the ground area in front of the door 3. The ranging sensor can be an ultrasonic ranging sensor, a laser ranging sensor, or an infrared ranging sensor based on the time-of-flight principle. It is preferred to use an integrated ultrasonic ranging sensor with dustproof and waterproof capabilities. A wave-transparent cover or transparent protective cover is set at the opening of the receiving slot to provide physical protection for the ranging sensor probe and prevent wind and sand from directly eroding and damaging the device.

[0052] Reference Figure 3 and Figure 4 A controller is arranged on the bottom wall of the receiving trough 21, and a comparator is installed inside the controller. The input terminal of the controller is electrically connected to the ranging sensor through a shielded cable or weather-resistant wire, and the control output terminal of the controller is electrically connected to the vibration component 51. The controller is used to output start and stop control signals to the vibration motor 511 or the vibration drive unit. In this embodiment, the controller has one or more sets of threshold values ​​for the height of sand accumulation in front of the door stored in advance. The controller periodically reads the ranging value of the ranging sensor and compares the measured distance from the bottom edge of the box door 3 to the ground with the preset reference distance. When the measured distance is less than the threshold value corresponding to the reference distance, that is, when it is determined that the height of sand accumulation in front of the box door 3 exceeds the set value, the controller sends a start command to the vibration component 51, so that the vibration component 51 drives the operating plate 52 to vibrate and perform the sand clearing action. After the vibration runs for a preset time, the controller stops outputting control signals, the vibration component 51 stops working, and then the controller can read the ranging value again and repeat the sand clearing process if necessary. To avoid fatigue and increased energy consumption caused by frequent start-stop cycles, the controller can also be set with upper and lower limit thresholds and time hysteresis logic. Sand clearing will only be initiated when the ranging value is continuously in an over-limit state and exceeds the set duration. After sand clearing, it will only be allowed to be triggered again when the ranging value recovers to a certain margin outside the normal range.

[0053] Reference Figure 1 and Figure 4The door 3 is equipped with a door lock mechanism, which includes a lock box fixedly installed on the door 3, a lock body rotatably connected to the lock box, a handle rotatably connected to the lock body, and a latch assembly for locking the door 3 to the side wall of the box 1 in the locked state. The handle can rotate relative to the lock body between a locked position, a pre-open position, and an unlocked position. A limit switch is provided on the inside of the door 3, and the limit switch is electrically connected to the controller. The detection element of the limit switch is arranged within the rotation range of the handle, so that when the handle is rotated from the locked position to the pre-open position, the limit switch switches from the off state to the on state and outputs a door lock pre-open state signal to the controller in the receiving slot 21. When the controller receives the door lock pre-open state signal, the controller drives the vibration motor 511 to start. When the sand cleaning action is completed and the set running time or vibration number is reached, the controller controls the vibration motor 511 to shut down.

[0054] The implementation principle of a digital primary and secondary integrated ring network box according to an embodiment of this application is as follows: the vibration motor 511 drives the cam 512 to rotate, the protrusion of the cam 512 pushes the push rod 513, causing the operating plate 52 to move away from the base 2. After the protrusion of the cam 512 no longer abuts the push rod 513, the spring 531 drives the operating plate 52 to reset, thereby realizing that the accumulated sand is shaken off and slides down the operating plate 52 to the side away from the box body 1, avoiding the box door 3 from being blocked in the state of high sand accumulation.

[0055] When the vibration component 51 drives the push rod 513 to reciprocate, the push rod 513 drives the slide bar 41 to slide back and forth along the width direction of the box body 1 via the first slide bar 63, the single-arm lever 61 and the second slide bar 64 in the linkage component 6. This causes the bristles 43 on the slide bar 41 to brush the back surface of the filter screen 132. The dust brushed off is discharged outside the box body 1 through the discharge hole 14 at the bottom of the fixed groove 13. Thus, while cleaning the sand accumulated in front of the box door 3, the breathable structure is simultaneously self-cleaned.

[0056] The distance sensor is installed in the receiving groove of the groove 12 to detect the height of sand accumulation on the ground in front of the box door 3 in real time. The controller automatically controls the start and stop of the vibration component 51 according to the detection result of the distance sensor, and can trigger the sand cleaning action in combination with the pre-opening state signal of the door lock mechanism. The solar panel 18 and the energy storage module work together to provide an independent power supply for the vibration motor 511 and the controller, so that the ring network box has the comprehensive functions of automatic detection, automatic sand cleaning, automatic filter cleaning and self-powered operation in harsh environments such as desert sandstorms.
