Description

Technical Field

[0001] This invention relates to the field of municipal infrastructure technology, and in particular to a PVC guardrail structure that can be flexibly assembled and disassembled. Background Technology

[0002] Guardrails, as a basic safety protection and area isolation facility, are widely used in municipal roads, construction sites, public activity areas, and various temporary or permanent boundaries. Currently, guardrails commonly found on the market, especially those made of PVC material, mainly adopt fixed or simple plug-in structures, and their function is primarily focused on basic physical isolation.

[0003] However, with the increasing complexity of application scenarios and the ever-increasing demands for public safety and management efficiency, traditional guardrail structures have gradually revealed the following technical shortcomings: Limited functionality and lack of intelligent sensing capabilities: Most traditional guardrails are purely passive structures that only serve as physical barriers after events such as collisions or overturning occur. They cannot detect and actively alarm for abnormal states such as impacts or damage in real time, requiring additional monitoring equipment or sensor networks, resulting in complex systems, high costs, and power supply and wiring problems.

[0004] Rigid structure and poor adaptability: The connection method between traditional guardrail components is fixed (such as welding and bolt hard connection). After installation, it is difficult to flexibly adjust the angle according to the site terrain (such as bends and corners), and it is also impossible to achieve quick and non-destructive disassembly and reassembly. This leads to inconvenient transportation and storage, low deployment efficiency, and difficulty in meeting the flexible needs of temporary activities or site changes.

[0005] Insufficient impact resistance and stability: When faced with vehicle or external impact, traditional guardrails often rely on the rigidity of the material itself to resist the impact, resulting in poor buffering and energy absorption. This can easily cause overall structural damage or severe deformation of the guardrail, and there is a risk of being knocked down or displaced, leading to secondary injuries. Although some products have added diagonal braces, they are mostly fixed installations and cannot dynamically enhance support and stability at the moment of impact.

[0006] Maintenance and response lag: Damaged guardrails usually require manual inspection to detect, and there is a delay in alarm and response. There is no channel to remotely and in real time report abnormal status information to the management center, which cannot meet the requirements of modern smart city management and security systems for "real-time perception and rapid response". Summary of the Invention

[0007] To overcome the shortcomings of existing technologies, this invention provides a PVC guardrail structure that can be flexibly assembled and disassembled. Existing activated carbon filters rely solely on the flow rate of the liquid itself due to gravity, resulting in slow liquid flow and low filtration efficiency. Traditional activated carbon filters also suffer from a single activated carbon filtration method and poor filtration effect.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A PVC fence structure that can be flexibly assembled and disassembled includes: Multiple support rods, with two horizontal bars installed between two adjacent support rods, and multiple vertical bars slidably sleeved on the two horizontal bars. An alarm is installed on each of the multiple support rods, and a locking rod is slidably connected to the bottom of each of the multiple vertical bars near the support rod. An adaptive buffer power supply mechanism includes four buffer cylinders, which are installed on both sides of a support rod, and one end of each buffer cylinder is slidably connected to a telescopic rod, which is fixedly connected to a corresponding crossbar. The positioning mechanism includes a mounting cylinder, which is movably sleeved on the support rod and fixedly connected to a corresponding buffer cylinder. The automatic diagonal bracing mechanism includes multiple diagonal bracing rods, which are movably mounted on corresponding vertical rods to provide angular support for the vertical and horizontal rods.

[0009] Preferably, the adaptive buffer power supply mechanism further includes an induction coil wound around the inner wall of the buffer cylinder, and the telescopic rod is made of magnetic material. The telescopic rod and the induction coil are inductively coupled, and the induction coil is connected to the corresponding alarm.

[0010] Preferably, a baffle is fixedly installed at one end of the telescopic rod, and a buffer spring is fixedly installed on one side of the baffle. One end of the buffer spring is fixedly connected to the inner wall of the buffer cylinder.

[0011] Preferably, both ends of the crossbar are provided with threaded grooves, and the telescopic rod is provided with threads, with the threaded grooves being threadedly connected to the corresponding telescopic rods.

[0012] Preferably, the positioning mechanism further includes multiple wedge-shaped cards, which are fixedly installed on the mounting cylinder, and a rubber pad is installed on one side of each wedge-shaped card, which is in contact with the support rod for pushing.

[0013] Preferably, the outer side of the mounting cylinder is threaded with a top cylinder, and the top of the top cylinder has a top edge opening, which is engaged with multiple wedge-shaped cards for pushing.

[0014] Preferably, a sliding rod is slidably connected to the vertical rod, the sliding rod is rotatably connected to the corresponding diagonal brace, and a force-bearing rod is fixedly installed at one end of the sliding rod.

[0015] Preferably, two guide blocks are fixedly installed on one side of the vertical rod. Each guide block has a movable groove on the side that is close to each other. A movable shaft is slidably connected to the inner wall of the movable groove, and the movable shaft is fixedly connected to the corresponding diagonal brace.

[0016] Preferably, a pull rod is slidably connected to the vertical rod, one end of the pull rod is fixedly connected to the corresponding buffer cylinder, and one end of the pull rod is rotatably connected to a hinge rod, which is rotatably connected to the corresponding locking rod.

[0017] Preferably, the vertical rod is threaded with a bolt, which engages with the corresponding horizontal rod.

[0018] Compared with the prior art, the beneficial effects that this invention can achieve are: I. Excellent flexibility and scalability Modular and quick assembly / disassembly: Through the sliding connection of support rods, horizontal bars, and vertical bars and the fixing method of bolts / threads, the guardrail can be quickly assembled and disassembled, which greatly improves the efficiency of transportation and storage and the flexibility of on-site deployment. It is suitable for temporary fencing, event setup and other scenarios.

[0019] Adjustable angle to adapt to complex terrain: The positioning mechanism allows the mounting cylinder to be fixed at different angles on the support rod, so that the crossbars on both sides can form a bending angle. This design enables the guardrail to flexibly adapt to non-straight areas such as road bends and site boundaries, breaking through the limitation of traditional guardrails that can only be spliced ​​in a straight line, and has a wider range of applications.

[0020] II. Integrated Intelligent Sensing and Early Warning System Self-powered impact-sensing alarm: The adaptive buffer power supply mechanism cleverly combines mechanical buffering with electromagnetic induction power generation. When impacted, the telescopic rod (magnetic material) moves relative to the induction coil inside the buffer cylinder, cutting the magnetic field lines and directly generating current to power the alarm. This achieves "passive triggering and instant alarm," eliminating the need for additional wiring or frequent battery replacements. The system is self-sufficient and highly reliable.

[0021] Multi-directional remote monitoring capability: Alarms and signal transmitters can be installed on each support pole. When any point is impacted and triggers an alarm, the signal can be remotely sent to the monitoring center, realizing distributed perception and remote real-time monitoring of the guardrail status, greatly improving the efficiency and response speed of security management.

[0022] III. Multi-level progressive passive security and stabilization mechanisms Primary buffer energy absorption: The buffer cylinder and telescopic rod structure, together with the buffer spring, effectively absorbs and dissipates impact energy through spring compression at the moment of impact, reducing damage to the guardrail itself and mitigating damage to the colliding object, embodying the flexible safety concept.

[0023] Level 2 Automatic Stabilization Enhancement: Automatic diagonal bracing mechanism: The impact force is transmitted through the force-bearing rod, driving the angle of the diagonal bracing rod to change, quickly forming a stable triangular support structure with the vertical and horizontal rods. This process is automatically and passively triggered, requiring no external intervention, which significantly enhances the overall anti-overturning and anti-deformation ability of the guardrail when subjected to impact.

[0024] Automatic grounding anchoring (Example 2): The displacement of the buffer cylinder caused by the impact is automatically driven by the linkage of the tie rod and the hinge rod to insert the clamp into the ground. This is equivalent to providing a dynamic "emergency ground anchor" for the guardrail, further preventing the guardrail from sliding or collapsing as a whole, and providing a deeper level of safety protection.

[0027] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified. Example

[0028] like Figures 1-7 As shown, this invention provides a PVC guardrail structure that can be flexibly assembled and disassembled, including multiple support rods 1, an adaptive buffer power supply mechanism 5, a positioning mechanism 6, and an automatic diagonal bracing mechanism 7. Two horizontal bars 2 are installed between two adjacent support rods 1, and multiple vertical bars 3 are slidably sleeved on the two horizontal bars 2. The two horizontal bars 2 and the multiple vertical bars 3 are combined to form a guardrail structure. The sliding sleeve of the vertical bars 3 on the horizontal bars 2 allows for easy disassembly and adjustment between the vertical bars 3 and the horizontal bars 2. Alarms 4 are installed on the upper part of each of the multiple support rods 1. The arrangement of multiple alarms 4 enables multi-directional monitoring. In use, a signal transmitter can also be mounted on the support rods 1 to remotely transmit the signal generated when the guardrail deforms, thereby forming remote monitoring. The bottom of the multiple vertical bars 3 near the support rods 1 is slidably connected. The guardrail has a locking rod 9 and an adaptive buffer power supply mechanism 5, which includes four buffer cylinders 51. The four buffer cylinders 51 are installed on both sides of the support rod 1, and one end of the buffer cylinder 51 is slidably connected to a telescopic rod 52. The telescopic rod 52 is fixedly connected to the corresponding horizontal bar 2. The sliding connection between the buffer cylinder 51 and the telescopic rod 52 gives the guardrail a certain degree of flexible buffering effect when it is deformed by impact. The positioning mechanism 6 includes an installation cylinder 61, which is movably sleeved on the support rod 1 and fixedly connected to the corresponding buffer cylinder 51. The horizontal bar 2 and the vertical bar 3 are fixed between the two support rods 1 by the installation cylinder 61. The automatic diagonal bracing mechanism 7 includes multiple diagonal bracing rods 73, which are movably installed on the corresponding vertical bar 3 for angular support of the vertical bar 3 and the horizontal bar 2.

[0029] The vertical rod 3 is threaded with a bolt 12, which is pressed against the corresponding horizontal rod 2. The bolt 12 is threaded with the vertical rod 3, so that when the bolt 12 rotates, it can press against the horizontal rod 2, thereby fixing the position of the vertical rod 3 and facilitating installation and disassembly.

[0030] like Figure 1 , Figure 4As shown, in this embodiment, the adaptive buffer power supply mechanism 5 also includes an induction coil 55, which is wound around the inner wall of the buffer cylinder 51. The telescopic rod 52 is made of magnetic material, and the telescopic rod 52 and the induction coil 55 are inductively coupled. The induction coil 55 is connected to the corresponding alarm 4. A baffle 53 is fixedly installed at one end of the telescopic rod 52, and a buffer spring 54 is fixedly installed on one side of the baffle 53. One end of the buffer spring 54 is fixedly connected to the inner wall of the buffer cylinder 51. When the guardrail is impacted, the buffer cylinder 51 and the telescopic rod 52 form a relative displacement, causing the telescopic rod 52 to move inside the buffer cylinder 51. At the same time, by utilizing the induction effect between the magnetic material of the telescopic rod 52 and the induction coil 55, the telescopic rod 52 moves and cuts the magnetic field, thereby causing the induction coil 55 to generate current and quickly supply power to the alarm 4, thus causing the alarm 4 to sound. At the same time, through the setting of the baffle 53 and the buffer spring 54, when the telescopic rod 52 is displaced, the buffer spring 54 is compressed, thereby forming a buffering effect.

[0031] Both ends of the crossbar 2 are provided with threaded grooves 8, and the telescopic rod 52 is provided with threads. The threaded grooves 8 are threadedly connected to the corresponding telescopic rod 52. The threaded connection between the telescopic rod 52 and the threaded grooves 8 facilitates the disassembly and installation of the telescopic rod 52 and the crossbar 2.

[0032] like Figure 1 , Figure 3 As shown, in this embodiment, the positioning mechanism 6 further includes multiple wedge-shaped cards 64, which are fixedly installed on the mounting cylinder 61. A rubber pad 65 is installed on one side of each wedge-shaped card 64. The rubber pad 65 is in a push-fitting engagement with the support rod 1. A top cylinder 62 is threaded onto the outer side of the mounting cylinder 61. A top edge opening 63 is opened at the top of the top cylinder 62. The top edge opening 63 is in a push-fitting engagement with the multiple wedge-shaped cards 64. When the top cylinder 62 is rotated, the top cylinder 62 moves through the threaded connection between it and the mounting cylinder 61. Through the action of the top edge opening 63 and the wedge-shaped surface of the wedge-shaped card 64, the wedge-shaped card 64 is pushed and deflected, and squeezed into the support rod 1, thereby fixing the mounting cylinder 61 onto the support rod 1. At the same time, the rubber pad 65 increases the friction between the wedge-shaped card 64 and the support rod 1, thereby increasing the fixing effect.

[0033] like Figure 1 , Figure 5As shown, in this embodiment, the automatic diagonal bracing mechanism 7 also includes a force-bearing rod 71. A sliding rod 72 is slidably connected to the vertical rod 3. The sliding rod 72 is rotatably connected to the corresponding diagonal bracing rod 73, and the force-bearing rod 71 is fixedly installed at one end of the sliding rod 72. Two guide blocks 74 are fixedly installed on one side of the vertical rod 3. Movable grooves 75 are opened on the side of the two guide blocks 74 that are close to each other. Movable shafts 76 are slidably connected to the inner wall of the movable grooves 75. The movable shafts 76 are fixedly connected to the corresponding diagonal bracing rods 73. The force-bearing rod 71 is located on the outer side of the guardrail. When the guardrail is impacted, the force-bearing rod 71 is the first part to be impacted. When the force-bearing rod 71 is impacted, it pushes the diagonal bracing rod 73 to change its angle through the sliding rod 72, causing the diagonal bracing rod 73 to tilt, thereby forming a diagonal support for the guardrail, making the entire guardrail more stable. At the same time, the sliding connection between the guide blocks 74, the movable grooves 75, and the movable shafts 76 can adapt to the lateral displacement when the angle of the diagonal bracing rod 73 changes, thus facilitating the smooth angle change of the diagonal bracing rod 73.

[0034] In operation, multiple support rods 1 are fixed to the ground. Mounting cylinders 61 are fitted onto the support rods 1, allowing different mounting cylinders 61 to be placed at different angles. This results in the horizontal bars 2 on both sides being positioned at different angles, creating corner guardrails in different applications, facilitating multi-functional use. When the position is fixed, rotating the top cylinder 62, which is threadedly connected to the mounting cylinder 61, moves the top cylinder 62. Through the action of the top edge 63 and the wedge-shaped surface of the wedge-shaped card 64, the wedge-shaped card 64 is pushed and deflected, pressing into the support rod 1, thus fixing the mounting cylinder 61 to the support rod 1. The rubber pad 65 further increases the friction between the wedge-shaped card 64 and the support rod 1, enhancing the fixing effect. When the guardrail is hit, the impact point first appears on the force-bearing bar 71. The force-bearing bar 71 pushes the sliding bar 72 to move, and the sliding bar 72 pushes the diagonal brace 73 to change angle, so that the diagonal brace 73 and the guardrail form a triangular support, making the support of the guardrail more stable. Simultaneously, when the guardrail is impacted, the buffer cylinder 51 and the telescopic rod 52 form a relative displacement, causing the telescopic rod 52 to move inside the buffer cylinder 51. At the same time, the magnetic material of the telescopic rod 52 and the induction coil 55 are used to induce a cutting magnetic field when the telescopic rod 52 moves, thereby causing the induction coil 55 to generate current and quickly supply power to the alarm 4, thus causing the alarm 4 to sound. At the same time, through the setting of the baffle 53 and the buffer spring 54, when the telescopic rod 52 is displaced, the buffer spring 54 is compressed, thereby forming a buffering effect. Example

[0035] like Figures 1-2As shown, this embodiment is a further optimization based on embodiment one. To better realize the present invention, the following configuration is specifically adopted: In this embodiment, a PVC guardrail structure that can be flexibly assembled and disassembled also includes a pull rod 10 slidably connected on the vertical rod 3, one end of the pull rod 10 being fixedly connected to the corresponding buffer cylinder 51, and one end of the pull rod 10 being rotatably connected to a hinge rod 11, which is rotatably connected to the corresponding locking rod 9.

[0036] In this embodiment, as described above, when the guardrail is impacted, a relative displacement occurs between the buffer cylinder 51 and the telescopic rod 52, which in turn causes the buffer cylinder 51 to move relative to the vertical rod 3. The buffer cylinder 51 drives the pull rod 10 to move, and the pull rod 10 drives the hinge rod 11 to move, which in turn pushes the locking rod 9 downward, so that the locking rod 9 is locked into the ground, increasing the fixing effect between the guardrail and the ground.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
