Technical Field

[0001] This utility model belongs to the field of guardrail technology, specifically relating to a chemical safety guardrail. Background Technology

[0002] Chemical safety barriers are important facilities used in chemical production, storage, and transportation sites to ensure personnel safety, equipment stability, and environmental safety. The chemical industry often involves flammable, explosive, toxic, harmful, and highly corrosive hazardous chemicals during production processes, and equipment operates under high temperature and high pressure conditions, which can easily lead to safety accidents such as fires, explosions, and leaks. Chemical safety barriers can effectively reduce accident risks through their functions of physical isolation, energy buffering, and risk barrier.

[0003] Traditional chemical safety barriers are mostly made of a single material (such as carbon steel or ordinary stainless steel), which has weak impact resistance and poor fire resistance. At the same time, the integral design means that partial damage requires replacement of the whole barrier, resulting in long maintenance time and increased operating costs for enterprises. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a chemical safety guardrail that solves the problems of traditional chemical safety guardrails, which are mostly made of a single material, have weak impact resistance and poor fire resistance, and whose integral design makes it inconvenient to maintain as the whole guardrail needs to be replaced when a part is damaged.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a chemical safety guardrail, comprising an installation plate, wherein limiting seats are fixed on both sides of the top surface of the installation plate, and the two sets of limiting seats are mirror images of the center line of the installation plate; a limiting slot on one side of the limiting seat slidably connects to both sides of a flame-retardant energy-absorbing core layer, and a top plate fixed at the top of the flame-retardant energy-absorbing core layer connects to the top surface of the limiting seat; an impact-resistant outer plate is provided on one side of the flame-retardant energy-absorbing core layer, and splicing plates fixed at both ends of the impact-resistant outer plate connect to the movable groove at the corner of the limiting seat; an explosion-proof mesh layer is provided on the other side of the flame-retardant energy-absorbing core layer, and the explosion-proof mesh layer connects to the rear side of the limiting seat.

[0006] The beneficial effects of this utility model are:

Furthermore, each layer can be quickly disassembled and assembled through the combination of bolts one, two, and three with nuts one, two, and three, increasing maintenance efficiency and reducing operating costs.

[0009] As a further improvement to the above technical solution: the bottom end of the mounting plate is fixedly provided with a base, and the bottom end of the base is flush with the bottom end of the impact-resistant outer plate.

[0010] The beneficial effects of this improvement are: the design of the base being flush with the bottom of the impact-resistant outer plate creates a stable support surface at the bottom of the device, while reducing the risk of residual chemical corrosive media.

[0013] The beneficial effect of this improvement is that the gap left provides expansion space for the flame-retardant energy-absorbing core layer.

[0014] In order to better withstand the impact of flames:

The bolts slide through the through hole opened by the limiting seat on the inner wall of one side of the movable groove, and a threaded nut is sleeved on the outside of the bolt.

[0020] To effectively buffer external mechanical forces:

[0021] As a further improvement to the above technical solution: the flame-retardant energy-absorbing core layer is made of aerogel flame-retardant felt material with an internal composite honeycomb glass fiber skeleton, a thermal conductivity of ≤0.03W / (m·K) at room temperature, an expansion ratio of ≥3 times above 300℃, and releases inert gas to inhibit combustion.

[0022] The beneficial effects of this improvement are: the aerogel flame-retardant felt expands when heated to form a heat insulation layer, the honeycomb skeleton enhances the toughness of the material, and it can be compressed and deformed when absorbing impact energy, effectively buffering mechanical external forces.

[0023] To facilitate subsequent maintenance of the flame-retardant energy-absorbing layer:

[0024] As a further improvement to the above technical solution: the positioning holes through both ends of the top plate are used to slide and connect to the bolts fixed at the top of the limiting seat, and the bolts are fitted with threaded nuts.

[0025] The beneficial effects of this improvement are: by rotating nut two, the connection between it and bolt two can be released, and the impact-resistant top plate can be pulled upward to disassemble the flame-retardant energy-absorbing layer, which facilitates later maintenance.

[0040] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0041] like Figure 1-6 As shown, a chemical safety guardrail includes a mounting plate 1. Limiting seats 101 are fixed on both sides of the top surface of the mounting plate 1, and the two sets of limiting seats 101 are mirror images of the centerline of the mounting plate 1. A limiting slot 1013 on one side of the limiting seat 101 slidably connects to both sides of a flame-retardant energy-absorbing core layer 8. A top plate 7 fixed to the top of the flame-retardant energy-absorbing core layer 8 connects to the top surface of the limiting seat 101. An impact-resistant outer plate 6 is provided on one side of the flame-retardant energy-absorbing core layer 8, and splicing plates 5 fixed to the ends of both sides of the impact-resistant outer plate 6 connect to movable slots 1011 at the corners of the limiting seat 101. An explosion-proof mesh layer 4 is provided on the other side of the flame-retardant energy-absorbing core layer 8, and the explosion-proof mesh layer 4 connects to the rear side of the limiting seat 101.

[0042] The mounting plate 1 is fixedly provided with a base 2 at its bottom end, and the bottom end of the base 2 is flush with the bottom end of the impact-resistant outer plate 6. The design of the base 2 being flush with the bottom end of the impact-resistant outer plate 6 makes the bottom of the device form a stable support surface, while reducing the risk of residual chemical corrosive media.

[0043] The limiting slot 1013 is located at the center of one side of the limiting seat 101. The front side of the limiting seat 101 presses and limits the impact-resistant outer plate 6, and the rear side of the limiting seat 101 presses and limits the explosion-proof mesh layer 4. The gap between the explosion-proof mesh layer 4 and the impact-resistant outer plate 6 and the limiting slot 1013 is the same. The gap is reserved for the expansion space of the flame-retardant energy-absorbing core layer 8.

[0044] The impact-resistant outer plate 6 is made of aluminum alloy reinforced with alumina ceramic particles, wherein the ceramic particles account for 25%-35% of the volume and have a particle size of 50-100μm. The aluminum alloy matrix is ​​of type 6061-T6 and has a surface hardness of ≥35HRC; it can better withstand the impact of flames.

[0045] The connecting plate 501 fixed on one side of the splicing plate 5 is slidably connected to the movable groove 1011, and a number of bolts 502 are fixed at equal intervals on the side of the connecting plate 501 facing away from the impact-resistant outer plate 6. The bolts 502 slide through the inner wall of one side of the movable groove 1011 and through the through hole 1012 opened by the limiting seat 101, and a threaded nut is sleeved on the outside of the bolts 502. By rotating the nut, the connection between the nut and the bolt 502 can be released, and the impact-resistant outer plate 6 can be pulled out to one side for disassembly, which is convenient for later maintenance.

[0046] The flame-retardant energy-absorbing core layer 8 is made of aerogel flame-retardant felt material with an internal composite honeycomb glass fiber skeleton. The thermal conductivity at room temperature is ≤0.03W / (m·K), and the expansion ratio above 300℃ is ≥3 times. It also releases inert gas to inhibit combustion. After the aerogel flame-retardant felt expands when heated, it forms a heat insulation layer. The honeycomb skeleton enhances the toughness of the material and compresses and deforms when absorbing impact energy, effectively buffering mechanical external forces.

[0047] The top plate 7 has positioning holes through both ends that are slidably connected to the bolts 9 fixed at the top of the limiting seat 101, and the bolts 9 are threaded and connected to the nuts 2. By rotating the nuts 2, the connection between the nuts 2 and the bolts 9 can be released, and the impact-resistant top plate 7 can be pulled upward to disassemble the flame-retardant energy-absorbing layer 8, which is convenient for later maintenance.

[0048] The explosion-proof mesh layer 4 is made of 304 stainless steel diamond mesh with a mesh area ≤25mm. 2 Wire diameter ≥ 3mm; constrains the spread of explosive shock wave.

[0049] Limiting plates 401 are fixed on both sides of the explosion-proof mesh layer 4, and several mounting holes through the limiting plates 401 are movably connected to several bolts 3 fixed on the rear side of the limiting seat 101. Nuts 3 are threaded on the outer side of the bolts 3. By rotating the nuts 3, the connection between them and the bolts 3 can be released, and the explosion-proof mesh layer 4 can be pulled out to one side for disassembly, which is convenient for later maintenance.

[0050] The working principle and usage procedure of this utility model are as follows: Before using this device, the user aligns the limiting plates 401 on both sides of the explosion-proof mesh layer 4 with the bolts 3 on the rear side of the limiting seat 101, passes them through the mounting holes, put on the nuts 3 and tighten them to complete the initial fixation of the explosion-proof mesh layer 4. The flame-retardant energy-absorbing core layer 8 is then embedded into the limiting slots 1013 of the limiting seat 101 on both sides. The positioning holes of the top plate 7 are aligned with the bolts 9 on the top of the limiting seat 101. The nuts 2 are put on and tightened appropriately, leaving room for subsequent fine-tuning. Insert the connecting plates 501 of the splicing plates 5 on both sides of the impact-resistant outer plate 6 into the movable groove 1011 at the corner of the limiting seat 101, push the outer plate to fit the flame-retardant energy-absorbing core layer 8, pass the bolt 502 through the movable groove 1011 and the through hole 1012, put on the nut and tighten them together to complete the overall installation. After the device is installed, carry it to the designated location, and then place the impact-resistant outer plate 6 facing the side with potential impact sources such as forklift driving lanes and material handling areas, with its outer surface directly exposed to the air. In environments with potential mechanical impacts and flame burns, when the guardrail is subjected to external impacts such as forklift collisions, the alumina ceramic particle-reinforced aluminum alloy material of the impact-resistant outer panel 6 first absorbs the impact force, transferring the energy to the flame-retardant energy-absorbing core layer 8. The honeycomb fiberglass skeleton of the core layer is compressed and deformed, absorbing and dispersing the energy, preventing the impact force from being transmitted to the explosion-proof mesh layer 4 and the mounting frame, ensuring the overall structural stability. When exposed to open flames or high temperatures, the aerogel flame-retardant felt of the flame-retardant energy-absorbing core layer 8 rapidly expands, filling the reserved gap between the impact-resistant outer panel 6 and the explosion-proof mesh layer 4, forming a dense heat insulation layer. This effectively blocks the transfer of flames and heat, delays the spread of fire, and protects the internal structure and the surrounding environment. In the event of an explosion, the 304 stainless steel diamond mesh of the explosion-proof mesh layer 4, with its high strength and unique mesh structure, constrains the direction and intensity of the explosion shock wave. At the same time, the impact-resistant outer panel 6 and the flame-retardant energy-absorbing core layer 8 work together to buffer and further attenuate the shock wave energy, reducing the harm of the explosion to the guardrail, surrounding equipment, and personnel.
