Description

Technical Field

[0001] The present invention relates to the technical field of highway engineering, and more specifically, to a safety protection device for slopes in highway reconstruction and expansion. Background Art

[0002] Highway reconstruction and expansion is an important project to improve transportation capacity, relieve traffic pressure, and enhance highway service levels. However, during the reconstruction and expansion process, the stability of slopes is one of the key issues. Due to factors such as construction excavation, rainfall erosion, and geological condition changes, slopes are prone to safety hazards such as landslides, collapses, and debris flows, seriously threatening construction safety and driving safety.

[0003] According to the invention patent with the Chinese patent number CN118407348A, a slope protection device for reconstructed and expanded highways is disclosed, which includes a buffer mechanism, a protection plate, a first support mechanism, and a second support mechanism; a protection plate is rotatably arranged on the bottom plate, and a second torsion spring is arranged between the protection plate and the bottom plate. A chute is opened at the rear end of the bottom plate, and an alarm mechanism is arranged in the chute. The alarm mechanism is connected to the protection plate through a connection mechanism; the buffer mechanism is arranged at the front end of the protection plate, the first support mechanism is arranged at the rear end of the protection plate, and the first support mechanism and the buffer mechanism are connected by a synchronous belt drive; two groups of second support mechanisms are arranged, and the two groups of second support mechanisms are connected by a synchronous belt drive, and the two groups of second support mechanisms are located between the first support mechanism and the protection plate. The second support mechanism is meshed with the connection mechanism through a transmission mechanism. This device can reduce the impact of materials, prevent the protection device from being damaged during the protection process, and improve the stability and service life of the protection.

[0004] However, there are still some problems in practice. The crushed stones that slide down the slope usually accumulate on the surface of the protection device, such as a baffle or a stone retaining net. As the accumulation amount increases, the weight borne by the device gradually increases, which may cause the protection device to deform, malfunction, or even be damaged. Traditional devices usually require manual or mechanical cleaning of the crushed stones. However, the terrain in the slope area is complex and the environment is harsh, and the cleaning work is time-consuming, laborious, and dangerous.

[0005] Therefore, we make improvements and propose a safety protection device for slopes in highway reconstruction and expansion. Summary of the Invention

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] In the solution of the present application:

[0021] 1. Through the buffer cleaning mechanism provided, when gravel falls on the protection device body, the protection net can effectively block the gravel from further falling onto the road, playing a preliminary protection role. At the same time, the gravel will slide onto the baffle of the protection device body, and the buffer spring at the bottom of the baffle can provide buffer protection for the baffle, absorbing the impact force and preventing the gravel from directly damaging the main body of the protection device body. As the gravel gradually accumulates on the baffle, when its weight exceeds a certain threshold, it will cause the baffle to move downward, thereby driving the trigger rod to descend synchronously. When the trigger rod descends, it will squeeze the push-button power switch. After the power switch is activated, the motor is activated. The output end of the motor drives the screw rod to rotate. While the screw rod rotates, it drives the displacement of the moving support. The moving support then pushes the connecting plate to move horizontally. When the connecting plate moves, the reset spring assembled at its bottom pulls the mounting plate and the scraper to descend, so that the bottom end of the scraper always fits the top end of the baffle. Through the sliding action, the scraper cleans the gravel accumulated on the surface of the baffle, preventing the continuous accumulation of gravel from affecting the function of the protection device body.

[0022] 2. Through the filtering mechanism provided, when rainwater and gravel mixed with rainwater slide down from the slope, they will fall into the storage box of the device together. The bottom of the storage box is designed with a filter pipe, which can effectively separate water and solid substances. Through the action of gravity, the water is filtered out under the action of the filter pipe and flows into the water storage box below for collection, while the storage box can retain the sliding gravel, preventing the gravel from further impacting other areas or entering the drainage system. The internal space of the water storage box is relatively large and can accommodate a certain amount of rainwater, providing the possibility for subsequent utilization.

[0037] Please refer to Figures 1 to 7 The present invention provides a technical solution: a safety protection device for highway reconstruction and expansion slopes, including a protection device body 1. A buffer cleaning mechanism 5 is provided inside the protection device body 1. The buffer cleaning mechanism 5 includes a moving support 501, a collision prevention plate 502, a motor 503, a buffer spring 504, a limit plate 505, a support plate 506, a push-button power switch 507, a cleaning scraper 508, a return spring 509, a mounting plate 510, a connecting plate 511, a lead screw 512, a chute 513, a baffle 514, and a trigger rod 515. The inner side of the moving support 501 is fixedly connected to the connecting plate 511. The bottom end of the connecting plate 511 is fixedly connected to the return spring 509. The bottom end of the return spring 509 is fixedly connected to the mounting plate 510. The bottom end of the mounting plate 510 is fixedly connected to the cleaning scraper 508;

[0038] A filtering mechanism 3 is provided inside the protection device body 1. The filtering mechanism 3 includes a water storage box 301, a connecting pipe 302, a storage box 303, and a filtering pipe 304. The bottom ends of the two storage boxes 303 are both fixedly connected to the filtering pipe 304. One end of each of the two filtering pipes 304 is threadedly connected to the water storage box 301.

[0039] As Figures 1 - 3 shown, as a preferred implementation, on the basis of the above method, further, a stabilizing frame 2 is connected to the front of the protection device body 1, and a protection net 4 is connected to the top of the protection device body 1.

[0040] Among the above components, a stabilizing frame 2 is connected to the front of the protective device body 1 to enhance the overall structural stability of the protective device body 1, ensuring that it remains stable during long-term use or when subjected to external forces such as falling gravel, strong winds, vibrations, etc., thereby improving the durability and reliability of the protective device body 1. The stabilizing frame 2 is connected to the protective device body 1 through a firm connection structure, which can disperse the externally applied pressure and prevent a single part from bearing excessive stress and causing deformation or damage. At the same time, a protective net 4 is connected to the top of the protective device body 1. The protective net 4 can cover the upper part of the protective device body 1 to block falling gravel or other sundries and prevent them from directly falling outside the protective device body 1 or onto the road. The protective net 4 is made of high-strength materials and has strong impact resistance, capable of intercepting and withstanding the impact force of large-scale falling objects. The combination of the stabilizing frame 2 and the protective net 4 forms a dual protection mechanism, which can not only effectively protect the road and driving safety but also extend the service life of the protective device body 1.

[0041] As Figures 1 - 3 shown, as a preferred embodiment, on the basis of the above method, further, a collision-proof plate 502 is fixedly connected to the top of the motor 503, and one end of the collision-proof plate 502 is fixedly connected to the outer wall of the protective device body 1.

[0042] Among the above components, a collision-proof plate 502 is fixedly connected to the top of the motor 503. The collision-proof plate 502 is made of high-strength impact-resistant materials and can play an effective buffering and protection role when external impacts or falling gravel pose a threat to the protective device body 1, preventing the motor 503 from being damaged due to direct force. One end of the collision-proof plate 502 is fixedly connected to the outer wall of the protective device body 1, forming an overall force-bearing system through a firm connection structure, which can disperse the impact force while further improving the durability and safety of the protective device body 1.

[0043] As Figure 6 shown, as a preferred embodiment, on the basis of the above method, further, the output end of the motor 503 penetrates through a side wall of the protective device body 1 and is fixedly connected to a lead screw 512. A chute 513 is opened inside the protective device body 1, and one end of the lead screw 512 is rotatably connected to the inner wall of the chute 513.

[0044] Among the above components, a chute 513 is provided inside the protective device body 1. The chute 513 is precisely processed and used in cooperation with the lead screw 512. The chute 513 provides a stable guiding function for the lead screw 512, ensuring that the lead screw 512 can operate smoothly during rotation and avoiding deviation or vibration.

[0045] As Figures 6 - 7As shown, as a preferred embodiment, on the basis of the above method, further, the movable support 501 is vertically slidably connected to the inner wall of the chute 513, and the lead screw 512 is threadedly connected to the movable support 501.

[0046] Among the above components, the lead screw 512 is threadedly connected to the movable support 501. The rotational motion of the lead screw 512 can be converted into the linear sliding of the movable support 501 through screw drive. When the motor 503 drives the lead screw 512 to rotate, the movable support 501 moves up and down along the inner wall of the chute 513 under the action of screw drive.

[0047] As Figures 6 - 7 shown, as a preferred embodiment, on the basis of the above method, further, a limiting groove 516 is formed in the inner wall of the other side of the protective device body 1, and a support plate 506 is fixedly connected to the inner wall of the protective device body 1. Limiting plates 505 are fixedly connected to the inner sides of both the support plate 506 and the inner side of the protective device body 1.

[0048] Among the above components, the support plate 506 plays a role in enhancing the structural strength of the protective device body 1, provides stable support for the key components inside the protective device body 1, and at the same time disperses the external force, avoiding deformation or damage of the protective device body 1 caused by long-term use or external impact. The support plate 506 is made of high-strength corrosion-resistant material and can adapt to complex environmental conditions, extending the service life of the protective device body 1.

[0049] As Figures 4 - 5 shown, as a preferred embodiment, on the basis of the above method, further, buffer springs 504 are fixedly connected to the tops of both limiting plates 505. A push-button power switch 507 is fixedly connected to the top of one of the limiting plates 505, and the push-button power switch 507 is electrically connected to the motor 503.

[0050] Among the above components, the buffer springs 504 are designed to absorb and relieve the energy generated by vibration or impact during the operation of the sliding components, playing a role in protecting the components of the protective device body 1 and improving the operation stability. The push-button power switch 507 is designed to be electrically connected to the motor 503, and the switch action is triggered by the displacement of the limiting plate 505. When the sliding components inside the protective device body 1 move due to external force or load change, causing the movement of the limiting plate 505, the buffer spring 504 will be compressed, and the limiting plate 505 will move downward accordingly, triggering the pressing contact of the push-button power switch 507, thereby starting the motor 503.

[0051] As Figures 4 - 6As shown, as a preferred embodiment, on the basis of the above method, further, a baffle 514 is vertically slidably connected to the inner wall of the protection device body 1. The top end of the buffer spring 504 is fixedly connected to the bottom end of the baffle 514. The bottom end of the baffle 514 is fixedly connected to a trigger rod 515, and the trigger rod 515 is placed on top of the push-button power switch 507.

[0052] Among the above components, the baffle 514 cooperates with the inner wall of the protection device body 1 through a precisely designed sliding structure and can slide smoothly in the vertical direction. The main function of the baffle 514 is to carry the sliding gravel or other external impact objects. When the baffle 514 bears the impact force or the weight of the accumulated gravel, the buffer spring 504 can effectively absorb the impact energy of the external pressure and reduce the damage to the baffle 514 and other structural components.

[0053] As Figures 1 - 3 shown, as a preferred embodiment, on the basis of the above method, further, a water storage box 301 is connected to the inner wall of the protection device body 1, and a connecting pipe 302 is fixedly connected to the top end of the water storage box 301.

[0054] Among the above components, the water storage box 301 is firmly combined with the overall structure of the protection device body 1 through a precisely designed installation method to ensure its stability and functionality in long-term use or force-bearing environments. The water storage box 301 is used to collect and store rainwater in the sliding gravel. Through reasonable space design, it can accommodate a large volume of water and avoid waste of water resources.

[0055] As Figures 1 - 3 shown, as a preferred embodiment, on the basis of the above method, further, two storage boxes 303 are connected to the inner wall of the protection device body 1.

[0056] Among the above components, the storage box 303 is firmly fixed to the inner wall of the protection device body 1 through a reasonable structural design. Its main function is to receive sundries such as gravel, sediment, and rainwater sliding from the top of the protection device body 1. The arrangement of the storage box 303 can not only centrally collect these sliding objects but also prevent them from directly scattering onto the road or other important areas, thereby improving the overall protection effect of the protection device body 1.

[0057] Specifically, when the present rainwater collection and intelligent distribution irrigation system in the photovoltaic field area is working / being used: when gravel falls on the protection device body 1, the protection net 4 can prevent the gravel from falling onto the road. When the gravel falls on the baffle 514, the buffer spring 504 at the bottom of the baffle 514 can provide certain protection for the baffle 514 to avoid damage to the protection device body caused by the gravel. When too much gravel accumulates on the baffle 514, the weight of the gravel can drive the baffle 514 to descend. When the baffle 514 descends, it can drive the trigger rod 515 to descend, and the trigger rod 515 then presses the push-button power switch 507. When the push-button power switch 507 is activated, it can start the motor 503. The output end of the motor 503 drives the lead screw 512 to rotate, and the lead screw 512 drives the moving support 501 to rotate. The moving support 501 can drive the connecting plate 511 to move. When the connecting plate 511 moves, the reset spring 509 at its bottom can drive the mounting plate 510 and the scraper to descend, so that the bottom end of the scraper always fits the top end of the baffle 514. The scraper can clean the gravel on the top end of the baffle 514 to prevent excessive accumulation of gravel on the baffle 514. When rainwater and gravel mixed with rainwater slide down from the slope, they will fall into the storage box 303 of the device together. The bottom of the storage box 303 is designed with a filter pipe 304, which can effectively separate water and solid substances. Through the action of gravity, the water is filtered out under the action of the filter pipe 304 and flows into the water storage box 301 below for collection. The storage box 303 can retain the sliding gravel to prevent the gravel from further impacting other areas or entering the drainage system. The internal space of the water storage box 301 is relatively large and can accommodate a certain amount of rainwater, providing the possibility for subsequent utilization.
