Description

Technical Field

[0001] The present invention relates to the technical field of highway protection, and in particular to a highway guardrail safety anti-collision device. Background Art

[0002] Cars traveling on highways travel at high speeds, and crash barriers located on both sides of the highways effectively prevent vehicles from crashing through the barriers in the event of an accident, thus ensuring personal safety. Currently, all highways and intercity roads are essentially protected by corrugated steel guardrails. The stress and reaction forces generated by the high-strength guardrail steel plates during a collision can cause significant damage to vehicles and personnel. Furthermore, the rigidity of corrugated steel material reduces vehicle deceleration, increasing the likelihood of vehicles turning back and colliding with the road, potentially leading to secondary and multiple accidents. Therefore, some corrugated steel guardrails are equipped with yellow rollers. When a car hits the steel guardrail, the rollers first contact the rollers, converting the impact force into rotational energy, effectively preventing the vehicle from losing control and forcibly correcting its direction of travel. However, since the rollers are integrally formed, the portion of the roller wall that comes into direct contact with the vehicle will shatter. Furthermore, the impact force will extend to the surrounding areas of the rollers, causing them to shatter. A broken roller cannot meet subsequent collision protection requirements, necessitating replacement of the entire roller, increasing replacement costs. Summary of the Invention

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0031] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0032] Example 1

[0033] Reference Figure 1-3 , which is a first embodiment of the present invention, provides a highway guardrail safety anti-collision device, which includes a protection unit 100, including two symmetrically arranged lower fixed plate groups 101 and a symmetrically arranged upper fixed plate group 102, the lower fixed plate group 101 and the upper fixed plate group 102 are arranged at the edge of the highway along the highway direction, side plates 103 are connected to both sides of the lower fixed plate group 101 and the upper fixed plate group 102, and a plurality of anti-collision components 104 are evenly and equidistantly arranged between the lower fixed plate group 101 and the upper fixed plate group 102.

[0034] The anti-collision component 104 includes a base 104a, which is buried underground, a support column 104b connected to the base 104a, and an anti-collision component 104c installed on the support column 104b. The anti-collision component 104c includes a plurality of anti-collision cylinders 104c-1 vertically sleeved on the support column 104b, and the anti-collision cylinder 104c-1 is composed of an upper body section with a "concave" cross-section and a lower body section with an inverted "convex" cross-section, and the upper body section and the lower body section are connected; the anti-collision cylinder 104c-1 is rotatably set on the support column 104b, and any two adjacent anti-collision cylinders 104c-1 are clamped with each other, and the rotation of one anti-collision cylinder 104c-1 will drive the other anti-collision cylinders 104c-1 to rotate. 4c-1 rotates, and liquid water 104c-2 is filled into the anti-collision cylinder 104c-1. The liquid water 104c-2 can be replaced by sand. The liquid water 104c-2 can make the anti-collision cylinder 104c-1 have stronger buffering ductility, reasonably absorb and reduce strong impact force, and an annular fluorescent layer 104c-3 is connected to the outer cylinder wall of the anti-collision cylinder 104c-1. At night, the fluorescent layer 104c-3 will reflect light when exposed to light, thereby improving the warning effect. Drivers can more clearly know the extension direction of the road through the reflection of the fluorescent layer 104c-3 on both sides of the road; and the support column 104b is set through the lower fixed plate group 101 and the upper fixed plate group 102.

[0035] During use, the anti-collision component 104c is assembled from multiple single anti-collision cylinders 104c-1, which are interconnected as a whole. When a car collides with the entire anti-collision component 104c, the anti-collision cylinder 104c-1 in contact with the vehicle will rotate under the force, and its rotation will also drive the entire anti-collision component 104c to rotate. The liquid water 104c-2 in the anti-collision cylinder 104c-1 increases the overall weight of the anti-collision component 104c. When converting the impact force into rotational energy, it is necessary to overcome part of the gravity, thereby consuming the impact force; at the same time, only the anti-collision cylinder 104c-1 in contact with the vehicle will be damaged, and it will not affect the anti-collision cylinder 104c-1 that has not contacted the vehicle. In subsequent maintenance, only the damaged anti-collision cylinder 104c-1 needs to be replaced separately, and the remaining anti-collision cylinders 104c-1 can continue to be used, reducing replacement costs.

[0036] Among them, the lower end of the anti-collision component 104c is connected to the support component 104d, and the support component 104d includes a support plate 104d-1 movably arranged at the lower end of the lowest anti-collision cylinder 104c-1, the support plate 104d-1 supports the anti-collision cylinder 104c-1, and a bearing seat 104d-2 connected to the inner wall of the support plate 104d-1, and the bearing seat 104d-2 is fixedly sleeved on the column wall of the support column 104b. When the anti-collision cylinder 104c-1 is subjected to force and rotates, the support plate 104d-1 can also be subjected to force and rotate synchronously, without affecting the normal rotation of the anti-collision cylinder 104c-1 to convert the impact force.

[0037] The anti-collision component 104c is connected to a pressing component 104e, which includes a pressure plate 104e-1 movably pressed on the upper end of the top anti-collision cylinder 104c-1. The lower end of the pressure plate 104e-1 is connected to a plurality of limiting plugs 104e-5 in a circular shape and evenly spaced. The upper end of the top anti-collision cylinder 104c-1 is provided with a plurality of limiting slots 104e-6 in a circular shape and evenly spaced, and the limiting plugs 104e-5 are inserted into the corresponding limiting slots 104e-6. By inserting the limiting plugs 104e-5 into the limiting slots 104e-6, the pressure plate 104e is pressed. -1 and the top anti-collision cylinder 104c-1 are horizontally connected as one, the ball bearing 104e-2 is embedded in the center of the pressure plate 104e-1, the threaded tube 104e-3 is connected to the inner ring of the ball bearing 104e-2, and the threaded section 104e-4 is opened on the support column 104b, and the threaded tube 104e-3 and the threaded section 104e-4 are threadedly connected, and the surface of the threaded tube 104e-3 is provided with anti-slip grooves. When rotating the threaded tube 104e-3, a tool is used to clamp the threaded tube 104e-3, and the tool can be a wrench, which drives the threaded tube 104e-3 to rotate.

[0038] Example 2

[0039] Reference Figure 1-5 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: a buffer assembly 104f is connected to the support assembly 104d, and the buffer assembly 104f includes a sliding block 104f-1 connected to the inner side wall of the support plate 104d-1, a support ring 104f-5 sleeved on the column wall of the support column 104b, a sliding groove 104f-2 opened on the annular side wall of the support ring 104f-5, a serpentine spring sheet 104f-3 connected to the groove wall of the sliding groove 104f-2, and a sliding rod 104f-4 connected to the arc in the sliding groove 104f-2, and the sliding rod 104f-4 is movable through the sliding block 104f-1 and the serpentine spring sheet 104f-3.

[0040] The buffer component 104f is connected to the alarm component 104g, which includes a trigger groove 104g-1 opened on the top wall of the sliding groove 104f-2, and a momentary press switch 104g-2 installed at the bottom of the trigger groove 104g-1. The pressing end of the momentary press switch 104g-2 extends into the sliding groove 104f-2. The pressing end of the momentary press switch 104g-2 is connected to the trigger block 104g with a right-angled trapezoidal cross section. -3, and the inclined surface of the trigger block 104g-3 is set toward the sliding block 104f-1, and the accommodating cavity 104g-4, the battery 104g-5 and the transmission device 104g-6 are set in the base 104a, and each transmission device 104g-6 has its own position information preset in advance, and the momentary press switch 104g-2, the battery 104g-5 and the transmission device 104g-6 are electrically connected through a wire.

[0041] During use, when a vehicle collides with the anti-collision component 104c, the anti-collision component 104c and the support plate 104d-1 will rotate, and the support plate 104d-1 will drive the sliding block 104f-1 to slide on the sliding rod 104f-4. When the sliding block 104f-1 moves, it compresses the serpentine spring piece 104f-3. The serpentine spring piece 104f-3 is deformed under force and offsets the rotational force, thereby buffering part of the impact force of the vehicle and improving the anti-collision component 104c. and when the sliding block 104f-1 slides in the sliding groove 104f-2, the sliding block 104f-1 will hit the inclined surface of the trigger block 104g-3. After the inclined surface of the trigger block 104g-3 is subjected to force, the pressing end of the momentary press switch 104g-2 moves upward, causing the momentary press switch 104g-2 to be triggered, and the transmission device 104g-6 sends its own position information to the traffic control system, reminding the traffic control department of the specific location of the traffic accident, thereby improving the rescue efficiency.

[0042] The remaining structures are the same as those of Example 1.

This embodiment is different from the second embodiment in that a water replenishing component 105 is provided on the anti-collision component 104, and the water replenishing component 105 includes a water replenishing component 105a provided on the anti-collision cylinder 104c-1, and a plurality of water guiding components 105b provided between any two adjacent anti-collision cylinders 104c-1. The plurality of water guiding components 105b are evenly distributed in a ring shape.

[0045] The water replenishment component 105a includes a water replenishment port 105a-1 opened on the top of the anti-collision cylinder 104c-1, and the cross-section of the water replenishment port 105a-1 is stepped, and a water replenishment plug 105a-2 elastically arranged in the water replenishment port 105a-1. The water guide component 105b includes a water guide pipe 105b-1 embedded in the upper end of the anti-collision cylinder 104c-1, and a support frame 105b-2 connected to the inner wall of the water guide pipe 105b-1, and the support frame 105b-2 and the inner wall of the water guide pipe 105b-1 are annular rods. There are multiple reinforcing rods connected to improve the structural strength of the connection between the support frame 105b-2 and the water pipe 105b-1, the top rod 105b-3 connected to the center of the upper end of the support frame 105b-2, and the sealing tube 105b-4 embedded in the lower end of the anti-collision cylinder 104c-1. The upper end of the sealing tube 105b-4 extends out of the anti-collision cylinder 104c-1, and the sealing tube 105b-4 is inserted into the water pipe 105b-1. The sealing tube 105b-4 matches the water pipe 105b-1, and the two are sealed and slipped. The upper end of the push rod 105b-3 is inserted into the sealing tube 105b-4, and the sealing ring 105b-5 is connected to the inner wall of the sealing tube 105b-4. The sealing disk 105b-6 is movably arranged on the upper end of the push rod 105b-3, and the sealing disk 105b-6 matches the sealing ring 105b-5. The annular side wall of the sealing disk 105b-6 is inlaid with a sealing ring, which improves the sealing performance between the two when the sealing disk 105b-6 is inserted in the sealing ring 105b-5, and is connected to the sealing ring 105b- 5 and the spring 105b-7 between the sealing disk 105b-6. In the figure, the spring 105b-7 is in a stretched state. The upper end of the sealing tube 105b-4 is connected to the limit tube through the support rod. The upper end of the sealing disk 105b-6 is connected to the limit rod. The limit rod is set through the limit tube so that the sealing disk 105b-6 can only move in the vertical direction. When the push rod 105b-3 is not inserted into the sealing tube 105b-4, the sealing disk 105b-6 is in the sealing ring 105b-5, blocking the sealing ring 105b-5.

[0046] During use, if there is no water source to supply liquid water 104c-2 in the installation area, before installing the anti-collision device, pull out the water supply plug 105a-2, fill the anti-collision cylinder 104c-1 with liquid water 104c-2 through the water supply port 105a-1, and then insert the water supply plug 105a-2 into the water supply port 105a-1. Then, the anti-collision cylinder 104c-1 filled with liquid water 104c-2 is transported to the installation area by vehicle, and then multiple anti-collision cylinders 104c-1 are assembled, and two adjacent anti-collision cylinders 104c-1 are connected through the water guide component 105b;

[0047] If there is a water supply in the installation area, the empty anti-collision cylinder 104c-1 is directly transported to the installation area by vehicle, and the anti-collision cylinder 104c-1 is installed on the support column 104b in sequence. The sealing tube 105b-4 of the upper anti-collision cylinder 104c-1 is inserted into the water pipe 105b-1 of the lower anti-collision cylinder 104c-1, and the top rod 105b-3 applies an upward thrust to the sealing disk 105b-6 in the sealing ring 105b-5. The sealing disk 105b-6 is forced to stretch the spring 105b-7 and detach from the sealing ring 105b-5, so that the two adjacent anti-collision cylinders 104c-1 are connected. At the same time, by inserting into the water pipe 105b-1 The sealing tube 105b-4 in the anti-collision cylinder 104c-1 is used to connect the two adjacent anti-collision cylinders 104c-1 into one, and then the water supply plug 105a-2 of the top anti-collision cylinder 104c-1 is opened, and liquid water 104c-2 is added to the water supply port 105a-1 of the anti-collision cylinder 104c-1.
