Description

Technical Field

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

[0002] As the scale of smart grids continues to expand, the operation and maintenance of its outdoor equipment are becoming increasingly complex, leading to a greater application of protective canopies on the tops of various distribution boxes. Snow removal tasks for equipment during severe weather conditions such as snowfall are also becoming more demanding.

[0003] Typically, protective canopies on top of electrical distribution boxes are used to shield them from daily wind and rain. However, during periods of continuous heavy snowfall in winter, personnel often need to intervene promptly to clear accumulated snow, thereby reducing pressure and preventing deformation of the box. During this process, workers must climb to the top of the distribution box without protection to manually remove snow. If the equipment surface is icy and slippery, this could lead to serious safety risks such as accidental falls. After completing this task, workers must then face another round of snowfall and clear snow from the top. This repeated climbing is time-consuming, laborious, and inefficient. If the snow is too hard and tools are used to forcefully break it down, it not only consumes physical strength but may also cause irreversible impact damage to the main structure of the distribution box. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a smart grid integrated distribution box, which solves the technical problems of extremely high safety hazards caused by manual snow removal and the easy impact damage to the box structure caused by external cleaning.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a smart grid integrated distribution box, comprising a distribution box body, a support frame fixed to the top of the distribution box body; a shielding assembly, comprising two protective baffles symmetrically and rotatably connected to the support frame; a drive assembly, fixedly mounted on the distribution box body; and a transmission execution assembly, mounted on the support frame and drively connected to the drive assembly, the transmission execution assembly comprising a helical drive component, two threaded sliding components threadedly connected to the helical drive component, and two push-pull linkages respectively hinged to the two threaded sliding components; the end of the push-pull linkage away from the threaded sliding components is hinged to the protective baffle, the rotation of the helical drive component drives the two threaded sliding components to move away from each other, so as to push the two protective baffles outward around the rotation point through the push-pull linkage.

[0006] Preferably, the support frame is provided with a guide groove, two threaded sliding parts are slidably engaged in the guide groove, and a screw drive is provided inside the guide groove.

[0007] Preferably, the drive assembly includes a driving rotary wheel, which is connected to at least two driven rotary wheels via a flexible transmission member, and the driven rotary wheels are fixed to a screw transmission member.

[0008] Preferably, the protective baffle is fixed with a mounting base on the side facing the support frame, the mounting base has a receiving groove, an elastic air chamber is fixed in the receiving groove, and the support frame is provided with a pressing protrusion corresponding to the position of the elastic air chamber.

[0009] Preferably, it also includes a vibration assembly, which includes a guide receiving tube and a reciprocating force transmission rod slidably disposed in the guide receiving tube, and the internal space of the elastic air cavity is connected to the guide receiving tube.

[0010] Preferably, one end of the reciprocating force transmission rod is fixed with a contact, an elastic vibration plate is fixed on the contact, a limit block is fixed inside the mounting base, and the contact slides through the mounting base and contacts the protective baffle.

[0011] Preferably, an airflow generating cylinder is fixed to the outside of the support frame, and a thrust piston is slidably provided at one end of the airflow generating cylinder. The thrust piston and the threaded sliding component are positioned correspondingly and are attracted to each other by a magnetic attraction component.

[0012] Preferably, a pulling member is fixed inside the airflow generating cylinder, one end of which is connected to the air-pushing piston, and an airflow sound-generating member is provided at the air outlet end of the airflow generating cylinder.

[0013] Preferably, a gap shield is provided between the tops of the two protective baffles, and an movable gap is left between the gap shield and the protective baffle. A flexible sealing layer is fixed on the gap shield, and the flexible sealing layer is attached to the surface of the protective baffle.

[0014] Preferably, a force-bearing connecting seat is fixed on the protective baffle, the end of the push-pull linkage away from the threaded sliding part is hinged to the force-bearing connecting seat, and the bottom end of the protective baffle is rotatably connected to the support frame through a set rotating shaft.

[0015] This invention provides a smart grid integrated distribution box. It has the following beneficial effects: 1. This invention solves the safety risks and impact damage to the box structure caused by manual snow removal in the prior art by adopting a shielding component, a driving component, and a transmission execution component including a screw drive component and a push-pull linkage component. This enables remote and controllable adjustment of the opening and closing state of the protective baffle on the top of the distribution box, thereby achieving the ultimate goal of safely and efficiently protecting the main body of the smart grid integrated distribution box by changing the support angle so that the snow loses stability and automatically slides off.

[0016] 2. This invention employs a mounting base, an elastic air chamber, a pressure protrusion, and a vibration assembly including a reciprocating force transmission rod and an elastic vibration plate. When the protective baffle is opened, the elasticity of the air chamber pulls the force transmission rod, automatically generating flutter. This effectively avoids the problem of snow forming a hard ice layer after repeated freezing and thawing under sunlight, which is difficult to completely remove by relying solely on tilting gravity. This greatly improves the de-icing effect and prevents long-term ice accumulation from causing fatigue deformation of the support frame or overload damage to the hinge points.

[0017] 3. This invention employs an airflow generator, a thrust piston, a puller, and an airflow sound generator. When the distribution box performs automatic snow removal, it can use the magnetic attraction and disengagement between the threaded sliding part and the thrust piston to compress air and blow the airflow sound generator. This effectively avoids the hidden danger of large pieces of ice and snow suddenly sliding down and injuring operators or pedestrians below or damaging surrounding equipment, and greatly improves the safety warning performance of the snow removal operation process.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1, please refer to the appendix. Figure 1 -Appendix Figure 7 This is the first embodiment of the present invention, which provides a smart grid integrated distribution box, including: a distribution box body 100, which is used to house and protect various electrical equipment and terminals in the smart grid; a support frame 200, which is fixed to the top outer side of the distribution box body 100 by bolt connection or welding, and is used to provide installation and support for other components; and a shielding assembly 300, which includes two symmetrically arranged protective baffles 310, each of which is connected to a lug via a rotating shaft 330, for example, a pin. The structure, hinge structure, or shaft and bushing matching structure is rotatably connected to the edge of the support frame 200. When the two protective baffles 310 are closed, their upper surfaces extend obliquely from the outer edge to the middle top, forming a pointed structure with a triangular cross-section; the drive assembly 400 is fixedly installed on the outer side wall of the distribution box body 100 or in the space below the support frame 200 to provide driving force for the system; and the transmission execution assembly 500 is installed on the support frame 200 and maintains a transmission connection with the drive assembly 400.

[0022] Please see the appendix Figure 2 -Appendix Figure 3The transmission actuator 500 includes a screw drive 510, two threaded sliding members 520, and two push-pull linkages 530. The screw drive 510, for example, is a bidirectional lead screw with opposite thread sections, a lead screw with opposite thread directions at both ends, or a combined lead screw formed by two short shafts with different thread directions connected by a coupling, and is rotatably mounted on the support frame 200. The two threaded sliding members 520 are threadedly connected to different thread sections of the screw drive 510, and each threaded sliding member 520 maintains a sliding fit with the support frame 200 to limit circumferential rotation with the screw drive 510. One end of each push-pull linkage 530 is hinged to the corresponding threaded sliding member 520, and the end of each push-pull linkage 530 away from the threaded sliding member 520 is hinged to one side of the corresponding protective baffle 310.

[0023] Please see the appendix Figure 2 -Appendix Figure 3 When the screw drive component 510 is driven by the drive assembly 400 to rotate around itself, since the threaded sections of the two threaded sliding components 520 have opposite rotation directions, the rotational motion of the screw drive component 510 is converted into linear motion in which the two threaded sliding components 520 move closer or further apart along the axial direction of the screw drive component 510. When the screw drive component 510 drives the two threaded sliding components 520 to move further apart, each threaded sliding component 520 applies a pushing force to the protective baffle 310 through the push-pull linkage 530. After being transmitted through the push-pull linkage 530, this pushing force causes the two protective baffles 310 to tilt outward around their respective rotation axes 330, thus opening the triangular apex structure of the protective baffle 310. During this opening process, the snow attached to the upper surface of the protective baffle 310 loses stability due to the change in the support angle and slides down the inclined surface of the protective baffle 310 under the action of its own gravity.

[0024] Conversely, when the screw drive component 510 rotates in the opposite direction, driving the two threaded sliding components 520 to move closer to each other, the push-pull linkage component 530 pulls the two protective baffles 310 to rotate inward around the rotation axis 330 until they return to the closed state. Through the structural configuration of the above-mentioned transmission execution component 500, the opening and closing state of the protective baffles 310 can be remotely and controllably adjusted, avoiding the safety risks and impact damage to the box structure caused by manual snow removal.

[0025] It should be noted that the drive component 400 in this embodiment can be a manual input device, such as a hand crank, folding handle or crank, or an electric driver, such as a DC geared motor, stepper motor or servo motor with self-locking function. When the drive component 400 is an electric driver, it can be used with an outdoor waterproof control switch for remote start and stop operation.

[0026] Example 2, please refer to the appendix. Figure 2 -Appendix Figure 3 This is the second embodiment of the present invention, based on the aforementioned embodiment 1. Further, a guide groove 210 is provided on the upper surface of the support frame 200. The guide groove 210 is a straight groove structure extending axially along the helical transmission member 510, and its cross-sectional profile can be rectangular, trapezoidal, or inverted T-shaped. The bottoms of both threaded sliding members 520 are provided with sliding protrusions adapted to the guide groove 210. Each sliding protrusion is embedded inside the guide groove 210 and can slide freely along the length of the guide groove 210. The inner sidewall of the guide groove 210 provides a limiting constraint perpendicular to the sliding direction for the threaded sliding member 520, preventing the threaded sliding member 520 from circumferentially deflecting when the helical transmission member 510 rotates, thus ensuring the consistency of the thrust direction. Meanwhile, the screw drive component 510 is located in the inner space of the guide groove 210, that is, the screw drive component 510 is arranged in the inner cavity of the guide groove 210 along the length direction of the guide groove 210. On the one hand, this makes the overall structure more compact, and on the other hand, the screw drive component 510 is protected by the side wall of the guide groove 210, reducing the erosion of the threaded mating surface by external rain, snow and sand.

[0027] Please see the appendix Figure 2 -Appendix Figure 3 Furthermore, the drive assembly 400 includes a rotary power source and a driving rotary wheel. The rotary power source is a waterproof geared motor with its output shaft arranged horizontally, which is fixedly installed on the side wall of the distribution box body 100. The driving rotary wheel is fixedly mounted on the output shaft of the rotary power source. The transmission actuation assembly 500 also includes a flexible transmission member 540 and at least two driven rotary wheels 550, each driven rotary wheel 550 being fixedly mounted on the end of each helical transmission member 510.

[0028] Flexible transmission element 540, such as a synchronous belt, multi-ribbed belt, V-belt, or toothed synchronous belt, surrounds the outer periphery of the driving rotary pulley and all driven rotary pulleys 550, and the inner surface of the flexible transmission element 540 maintains meshing or frictional contact with the outer peripheral surfaces of the driving and driven rotary pulleys 550, respectively. When the rotary power source is started, its output shaft drives the driving rotary pulley to rotate, and the driving rotary pulley synchronously transmits the rotational motion to all driven rotary pulleys 550 through the flexible transmission element 540, thereby driving multiple helical transmission elements 510 to rotate synchronously and in the same direction.

[0029] Please see the appendix Figure 2 -Appendix Figure 3Through the aforementioned synchronous transmission configuration, when the area of ​​the protective baffle 310 above the distribution box is large, the driving torque of a single screw drive component 510 is insufficient, or the span is too large, causing the lead screw to bend and deform, two or more screw drive components 510 can be arranged at intervals along the length of the protective baffle 310 and driven synchronously by the same rotational power source. This ensures that the rotation angle and speed of each screw drive component 510 are consistent, and that the displacement of each threaded sliding component 520 is equal, avoiding the torsional torque on the protective baffle 310 caused by asynchronous action due to the push-pull linkage 530. Conversely, if this synchronous transmission structure is lacking, when multiple screw drive components 510 are driven independently, the difference in stroke of each threaded sliding component 520 will cause the protective baffle 310 to become skewed and stuck during opening or closing, which in severe cases may lead to the breakage of the rotating shaft 330 or plastic deformation of the protective baffle 310.

[0030] Example 3, please refer to the appendix. Figure 1 -Appendix Figure 7 This is the third embodiment of the present invention. Based on the aforementioned embodiment 2, this embodiment adds an auxiliary de-icing structure to further solve the problem that the snow attached to the surface of the protective baffle forms a hard ice layer after repeated freeze-thaw cycles, which is difficult to completely remove by simply relying on tilting gravity.

[0031] Specifically, each protective baffle 310 has a mounting base 600 fixed on its inner lower surface facing the support frame 200. The mounting base 600 is made of metal or high-strength engineering plastic and is fixedly connected to the lower surface of the protective baffle 310 by bolts or welding. The mounting base 600 has a receiving groove, which is a countersunk hole or strip groove structure formed by the inward indentation of the lower surface of the mounting base 600. An elastic air chamber 620, such as a rubber airbag or a silicone corrugated tube, is fixedly installed in the receiving groove. The upper surface of the support frame 200 and the corresponding position of each elastic air chamber 620 in the corresponding direction are provided with a pressing protrusion 220. The pressing protrusion 220 is a protrusion structure that protrudes upward from the upper surface of the support frame 200, and its top can be provided with an arc transition surface or a wedge-shaped guide slope.

[0032] Please see the appendix Figure 1 With appendix Figure 7When the protective baffle 310 is in a fully closed state and adheres to the upper surface of the support frame 200, the pressing protrusion 220 extends into the receiving groove and abuts against the lower surface of the elastic air chamber 620, compressing the elastic air chamber 620 upward, thus reducing its internal volume and increasing its internal gas pressure. When the protective baffle 310 is driven by the push-pull linkage 530 to tilt outward around the rotation axis 330 and open, the mounting base 600 rises synchronously with the protective baffle 310, and the elastic air chamber 620 gradually detaches from the pressing contact with the pressing protrusion 220. During the detachment process, the elastic air chamber 620 expands outward to return to its initial shape due to the elastic recovery force of its own material or the internal air pressure difference, increasing its internal volume.

[0033] Furthermore, the distribution box also includes a vibration assembly 700, which includes a guide receiving tube 710 and a reciprocating force transmission rod 720. The guide receiving tube 710 is a cylindrical shell closed at one end and open at the other end, and is fixedly installed inside or on the side of the mounting base 600. The reciprocating force transmission rod 720 is slidably installed at one end of the guide receiving tube 710, and the outer peripheral surface of the reciprocating force transmission rod 720 maintains a sliding seal fit with the inner wall of the guide receiving tube 710. The interior of the elastic air chamber 620... The space is connected to the internal cavity of the guide receiving tube 710 through a connecting pipe, such as a flexible rubber tube or a drilled channel built into the mounting base 600. The guide receiving tube 710 is provided with a reset elastic element, such as a helical compression spring or a gas spring. One end of the reset elastic element is connected to the inner wall of the closed end of the guide receiving tube 710, and the other end is connected to the end of the reciprocating force transmission rod 720. The reset elastic element always applies a pulling force to the reciprocating force transmission rod 720, causing it to contract toward the inside of the guide receiving tube 710.

[0034] Please see the appendix Figure 5 -Appendix Figure 6 When the elastic air chamber 620 is compressed and contracted by the pressing protrusion 220, the gas inside is forced into the guide receiving tube 710, pushing the reciprocating force transmission rod 720 to overcome the tension of the reset elastic member and extend outward; when the protective baffle 310 opens, the elastic air chamber 620 disengages from the pressing protrusion 220 and elastically recovers, the gas in the guide receiving tube 710 flows back to the elastic air chamber 620, and the reset elastic member simultaneously pulls the reciprocating force transmission rod 720 back into the guide receiving tube 710.

[0035] A contact 740 is fixed to one end of the reciprocating force transmission rod 720 that extends out of the guide receiving tube 710. The contact 740 is a columnar force transmission member with a large end face at one end. An elastic vibration plate 750, such as a spring steel strip or a beryllium copper alloy spring, is fixed on the side wall of the contact 740. A limit stop 630 is fixed inside the mounting base 600. The limit stop 630 is a rigid shoulder structure that protrudes from the inner wall of the mounting base 600. Its position and the end of the elastic vibration plate 750 form spatial interference in the motion path.

[0036] When the reciprocating force transmission rod 720 retracts rapidly under the pull of the reset elastic element, the elastic vibration plate 750 fixed on the contact 740 then retracts. The end of the elastic vibration plate 750 abuts against the limit block 630 at the end of the retraction stroke. After the collision, the reciprocating force transmission rod 720 continues to retract under the action of inertia, while the end of the elastic vibration plate 750 is blocked by the limit block 630 and undergoes elastic bending deformation. Subsequently, high-frequency reciprocating flutter occurs under the action of elastic restoring force.

[0037] The flutter is transmitted to the inner surface of the protective baffle 310 via the contact 740, causing the protective baffle 310 to vibrate. At the same time, the end face of the contact 740 repeatedly impacts the lower surface of the protective baffle 310 under the drive of the reciprocating force transmission rod 720, causing elastic deformation of the local metal surface of the protective baffle 310, thereby cracking or peeling off the ice layer attached to the upper surface of the protective baffle 310.

[0038] Example 4, please refer to the appendix. Figure 4 -Appendix Figure 8 This is the fourth embodiment of the present invention, which is based on the aforementioned embodiment 2 or 3, and provides a perceptible warning signal to people in the surrounding area during the snow removal operation.

[0039] Please see the appendix Figure 7 -Appendix Figure 8 Specifically, an airflow generating cylinder 800 is fixed to the outside of the support frame 200. The airflow generating cylinder 800 is a cylindrical shell with one end closed and the other end having an air outlet. Its axial direction is parallel to the axial direction of the screw drive component 510. A thrust piston component 810 is slidably arranged inside the airflow generating cylinder 800. The outer peripheral surface of the thrust piston component 810 and the inner wall of the airflow generating cylinder 800 maintain an airtight sliding fit. The side surface of the thrust piston component 810 facing the closed end of the airflow generating cylinder 800 and the inner wall of the airflow generating cylinder 800 together form a variable volume compressed air chamber. The side end face of the thrust piston component 810 away from the closed end corresponds to the threaded sliding component 520 in spatial position, and the two are attracted to each other by magnetic attraction components, such as permanent magnet pairs embedded on the end face of the thrust piston component 810 and the side of the threaded sliding component 520, or ferromagnetic blocks and magnets respectively disposed on the two, which attract each other.

[0040] An actuating element 820, such as a helical tension spring, is fixed inside the airflow generating cylinder 800. One end of the actuating element 820 is connected to the inner wall of the closed end of the airflow generating cylinder 800, and the other end is connected to the end face of the thrust piston 810 facing the closed end. The actuating element 820 always applies a pulling force to the thrust piston 810 toward the open end of the airflow generating cylinder 800.

[0041] Please see the appendix Figure 7 -Appendix Figure 8 When the threaded sliding member 520 slides along the guide groove 210 to a position where it overlaps with the thrust piston member 810 in the axial direction, the magnetic attraction between the magnetic attraction members overcomes the pulling force of the pulling member 820, pulling the thrust piston member 810 towards the direction closer to the threaded sliding member 520, that is, towards the opening end of the airflow generating cylinder 800. At this time, the volume of the compressed air chamber increases and the internal air pressure decreases.

[0042] When the threaded sliding member 520 continues to slide and is misaligned axially with the thrust piston member 810, and the magnetic force between them weakens to less than the pulling force of the pulling member 820, the pulling member 820 pulls the thrust piston member 810 back towards the closed end of the airflow generating cylinder 800, rapidly compressing the air in the compressed air chamber, causing the air pressure inside the compressed air chamber to rise sharply. The airflow generating cylinder 800 is provided with an airflow sound generating member 830, such as a whistle-type sound generator, a reed-type buzzer, a ball valve-type airflow whistle, or a membrane-type buzzer. The high-pressure airflow is ejected at high speed from the airflow generating end and blown towards the airflow sound generating member 830, causing the airflow sound generating member 830 to produce continuous and sharp audio vibrations, emitting a warning sound to the surrounding environment.

[0043] The warning sound alerts operators and pedestrians below or nearby to take precautions when the distribution box is performing remote automatic snow removal, preventing large chunks of ice and snow from sliding down and injuring people or damaging surrounding equipment.

[0044] Example 5, please refer to the appendix. Figure 1 -Appendix Figure 7 This is the fifth embodiment of the present invention. Based on any of the preceding embodiments, this embodiment adds an active avoidance shielding structure to solve the problem that there is a longitudinal gap at the top junction of the two protective baffles 310 in the closed state, and that rain, snow and sand may seep into the interior of the support frame 200 through the gap.

[0045] Specifically, a gap shield 900 is provided above the top junction gap between the two protective baffles 310. The gap shield 900 is a strip-shaped cover plate extending along the length of the protective baffle 310, and its cross-section can be inverted V-shaped, arc-shaped, or flat. A vertical movable gap is left between the gap shield 900 and the upper surface of each protective baffle 310. The size of the movable gap is greater than the vertical displacement of the top edge of the protective baffle 310 when it rotates around the rotation axis 330, so as to ensure that the gap shield 900 will not interfere with the normal opening and closing action of the protective baffle 310. A flexible sealing layer 910 is fixed to the bottom surface of the gap shield 900, such as an EPDM rubber sheet, a silicone rubber scraper, or a polyurethane elastomer sealing lip. The lower edge of the flexible sealing layer 910 is respectively attached to the upper surface of the two protective baffles 310. When the protective baffles 310 are at different opening and closing angles, the flexible sealing layer 910 always maintains contact with the upper surface of the protective baffles 310 due to its own elastic deformation.

[0046] Please see the appendix Figure 1 With appendix Figure 7 When the protective baffle 310 is in the closed state, the flexible sealing layer 910 covers the longitudinal gap at the junction of the tops of the two protective baffles 310, preventing external rainwater and dust from falling into the support frame 200 through the gap, thus avoiding corrosion or blockage of the screw drive component 510 and the threaded sliding component 520. As the protective baffle 310 tilts outward to open, the top edges of the two protective baffles 310 move to the sides and downward respectively, and the distance between them and the gap shielding component 900 changes. At this time, the flexible sealing layer 910 adapts to the surface contour of the protective baffle 310 by bending or sliding, and always maintains the shielding effect.

[0047] Meanwhile, because there is a movable gap between the gap shield 900 and the protective baffle 310, the protective baffle 310 will not collide hard with or get stuck with the gap shield 900 during opening or closing. Through the above configuration, the sealing and protection function of the top gap and the degree of freedom of movement of the protective baffle 310 are taken into account, avoiding the defects of traditional rigid sealing structures that hinder the opening and closing movement of the shield.

[0048] Based on the above embodiments, the complete workflow of this smart grid integrated distribution box during snowfall is as follows: In the initial state, the two protective baffles 310 are closed, forming a triangular apex structure. The pressure protrusion 220 compresses the elastic air chamber 620, keeping it in a compressed state. The reciprocating force transmission rod 720 of the vibration assembly 700 remains extended. When the snow on the upper surface of the protective baffles 310 accumulates to the required thickness, the operator starts the rotary power source via a remote control switch. The output shaft of the rotary power source drives the active rotary wheel to rotate. The active rotary wheel synchronously drives each driven rotary wheel 550 to rotate via the flexible transmission component 540, thereby driving the screw transmission component 510 to rotate around its own axis. Driven by the screw transmission component 510, the two threaded sliding components 520 move away from each other along the guide groove 210. Through the push-pull linkage 530, the thrust is transmitted to the force-bearing connecting seat 320 of the protective baffles 310, pushing the two protective baffles 310 to tilt outward and open around the rotation axis 330. During this opening process, the snow attached to the upper surface of the protective baffle 310 slides off along the inclined surface under the action of gravity, thus achieving removal.

[0049] As the protective baffle 310 opens, the mounting base 600 rises synchronously with it. The elastic air chamber component 620 disengages from the pressure of the pressure protrusion 220 and elastically returns to its original position. The internal gas flow causes a decrease in the air pressure inside the guide receiving tube 710. The reset elastic component pulls the reciprocating force transmission rod 720 back. The elastic vibration plate 750 on the contact 740 collides with the limiting block 630, generating high-frequency vibration. This vibration is transmitted to the protective baffle 310, cracking and peeling off the residual ice layer on the surface. At the same time, the threaded sliding component 520 magnetically couples with and disengages from the thrust piston component 810 during sliding, triggering the thrust piston component 810 to rapidly compress the air inside the airflow generator 800. The high-pressure airflow blows towards the airflow sound-emitting component 830, emitting a warning sound to alert surrounding personnel to take safety precautions.

[0050] After the snow is cleared, the operator controls the rotary power source to rotate in the opposite direction, causing the threaded sliding parts 520 to move closer together. Through the push-pull linkage 530, the protective baffle 310 is pulled inward around the rotation axis 330 until it is completely closed. The pressure protrusion 220 re-compresses the elastic air chamber 620, restoring it to its compressed state. Simultaneously, the flexible sealing layer 910 on the gap shield 900 covers the top gap between the two protective baffles 310, restoring the protective state and preparing it for the next use.
