Description

Technical Field

[0001] This utility model relates to the field of safety warning equipment technology, and in particular to a portable safety warning sign device. Background Technology

[0002] In complex construction environments, especially in long-distance oil and gas pipeline projects and field maintenance operations, the scientific deployment of safety warning signage systems plays a crucial role in defining hazardous areas, conveying safety warnings, and guiding behavioral norms. Analysis has revealed significant limitations in the application of traditional safety warning signs in such projects, specifically in the following four aspects:

[0003] First, due to complex terrain and unpredictable weather conditions (such as sudden strong winds), traditional signs generally suffer from insufficient stability, making them prone to tilting, falling, or rotating, significantly reducing the visibility and directionality of warning information. Second, in terms of installation adaptability, traditional signs mainly rely on insertion into soft ground, but in actual operations, they often encounter hard surfaces such as rocks and frozen soil, rendering conventional installation methods ineffective. Third, regarding visibility control, existing signage systems generally lack all-weather warning capabilities: during the day, due to the influence of sloping terrain, their placement angles are difficult to meet the spherical visual space coverage standards required by regulations; at night, the warning effect is weakened due to insufficient reflective materials and lack of auxiliary lighting. Finally, in terms of engineering mobility, traditional signs are mostly integral structures that are difficult to disassemble and transport, making it difficult to adapt to the needs of rapid relocation of multiple work areas. This not only increases transportation costs but also easily creates blind spots in temporary work areas, directly affecting the ability of workers to identify and avoid dynamic risks.

[0004] The utility model patent with announcement number CN211827902U proposes a flip-type intelligent ground-insertion sign, which has a flip-type sign and an adjustable ground insert, which can meet the adjustment of the sign's visible space and the stability of the ground insert after it is inserted into the ground.

[0005] However, the aforementioned patent has several drawbacks in field operations such as long-distance oil and gas pipelines, primarily in the following four aspects: First, the device relies on motor drive and external power supply, which conflicts with certain outdoor and field operations. Some operations, especially oil and gas operations, require explosion-proof ratings for equipment, and the introduction of a motor system necessitates explosion-proof certification modifications, significantly increasing technical adaptation costs. Second, the need for external power supply not only requires additional temporary power operation permits, extending the approval cycle, but also necessitates the configuration of mobile power supply devices, significantly increasing operational complexity and economic costs. Third, the device is only suitable for geological conditions with soft soil. When encountering hard strata (such as rock layers or permafrost) or special weather conditions, the contact between the four-legged support and the ground makes it difficult to ensure structural stability. Fourth, its nighttime warning capability is reduced in outdoor operations without lighting.

[0006] Utility model CN211948074U discloses a portable safety warning device for road construction, including a mobile base with a broadcaster. This device can be used at night to alert passersby to ongoing construction. The broadcaster and LED display provide both visual and audible alerts. Utility model CN207473801U discloses a portable safety warning device, including a suction cup with a detection sensor at the bottom of the housing. A battery, a microcontroller, and a rotary motor are respectively installed inside and in the upper part of the housing, facilitating fixation and warning, enabling rapid detection, and offering convenient, simple, and efficient operation.

[0007] Both of the above patents can be used for safety warnings at construction sites. However, given that their design and construction include many components, and even require additional battery and motor systems, this characteristic makes the overall device quite bulky and lacks the advantages of being easy to move and carry. This limits its flexible application in diverse usage scenarios, especially in complex construction environments, particularly in long-distance natural gas pipeline construction projects and field maintenance operations.

[0008] Utility model CN206931161U discloses a portable safety warning sign, including a detachable LED dynamic display warning sign and a retractable tripod. The tripod is equipped with locking components that work in conjunction with the sign, and the bracket is telescopic and height-adjustable. Utility model CN210039434U proposes a portable safety warning sign, including a display panel, a base, and a bracket with a cavity. Connecting blocks are hinged to both ends of the base, and pins pass through both ends of the connecting blocks, allowing the bracket to be folded up for easy transport.

[0009] Both of the above patents can be used for safety warnings at construction sites and have the advantages of being portable and easy to transport. However, in complex environments such as slopes or soft geology, especially in projects such as the construction of long-distance natural gas pipelines, these devices cannot effectively remain upright, are prone to falling over, and are difficult to achieve stable wind protection, thus limiting their application effectiveness in other application scenarios.

[0010] The invention patent application with publication number CN116732913A proposes a foldable portable safety warning frame, which includes a box body, a support rod and a movable rod forming a foldable base. The two ends of the movable rod are movably connected to form a closed frame. The opposite movable rods are parallel and of the same length. The adjacent movable rods can rotate relative to each other. However, it is not easy to carry, has a complicated installation process, and is not easy to store.

[0011] The aforementioned warning racks are easy to carry and install in complex terrains. However, the orientation of their safety signs is fixed and cannot be flexibly adjusted according to diverse terrain conditions such as slopes to ensure that the effective area of ​​the safety signs can be effectively adjusted. Only when the safety signs are on or inside the surface of the visual space can the observer's correct recognition rate of graphic symbol elements reach 85% (GB / T2893.5-2020). Therefore, they are not suitable for oil and gas long-distance pipeline construction projects and field maintenance operations that are often carried out in the field.

[0012] In view of the above reasons, this utility model proposes a portable safety warning sign device, which can solve the problem of the limitations of traditional safety warning signs in construction sites that are scattered, highly mobile, and have limited traffic conditions, especially in the construction of long-distance oil and gas pipelines.

[0036] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] like Figure 1-4 As shown, this utility model provides a portable safety warning sign device, including: a base 9, a support rod, and a safety warning sign slot 1 connected sequentially from bottom to top. A downwardly extending ground plug 10 is detachably connected to the bottom center of the base 9. Multiple horizontally extending brackets 12 are provided on the outer side of the base 9. The bottom end of the support rod is detachably connected to the center of the surface of the base 9. The bottom of the safety warning sign slot 1 is connected to the top of the support rod through an angle adjustment mechanism. An explosion-proof warning light 5 is installed on the outer side of the top of the support rod.

[0040] Specifically, the bottom of the ground insert 10 is conical, and four arc-shaped insert pieces 11 are evenly arranged on the outer periphery of the ground insert 10 and vertically integrated with it. The bottom of the arc-shaped insert pieces 11 is rounded and relatively sharp. The above structure allows this device to be used on both hardened and softened surfaces. When used on hardened surfaces, the ground insert 10 can be removed and supported by the base 8 and the brackets 12 on its outer side, so that it can stand stably in various scenarios. Weights can also be placed on each bracket 12 to further prevent it from tipping over. On softened surfaces, the four arc-shaped insert pieces 11 make it easier to insert into the ground and further stabilize the main body to prevent it from rotating.

[0041] The safety warning sign slot 1 is a U-shaped structure formed by three aluminum alloy rods with V-shaped cross-sections connected vertically at their ends. Two rods are arranged vertically and one is arranged horizontally. The length of the horizontal aluminum alloy rod is greater than the length of the vertical aluminum alloy rod. Each aluminum alloy rod consists of two aluminum alloy sheets with their long sides joined together to form a V-shaped groove. This allows the safety warning sign required for the application scenario to be inserted into and confined within the V-shaped groove from the top of the safety warning sign slot 1.

[0042] The angle adjustment mechanism includes a universal ball 2 located at the bottom center of the safety warning sign slot 1 and a universal ball slot 3 located at the top of the support rod that is adapted to the universal ball 2. A first locking screw 4 is provided on the outside of the universal ball slot 3 to limit the rotation angle of the universal ball 2. The end of the first locking screw 4 extends into the universal ball slot 3 through a screw hole from the outside of the universal ball slot 3, and presses the universal ball 2 inward to achieve a fixed effect at a certain angle. The universal ball 2 can meet the corresponding angle of the spherical visual space of the standard effective working area.

[0043] In this embodiment, the support rod includes a first rod 6, a second rod 7, and a third rod 8 that are connected in a telescopic manner from top to bottom. The outer side of the top end of the second rod 7 is provided with a second locking screw 13 for limiting the extension length of the first rod 6. The outer side of the top end of the third rod 8 is provided with a third locking screw 14 for limiting the extension length of the second rod 7. The universal ball groove 3 is provided at the top end of the first rod 6 and can be adapted to rotate with the universal ball 2 provided at the bottom of the safety warning sign groove 1. The bottom end of the third rod is detachably connected to the base.

[0044] The explosion-proof warning light 5 is a ring-shaped device fitted around the top of the first pole 6, and is powered by a built-in battery. The omnidirectional ball joint ensures the effective spherical visual space corresponds to the specified angle, while the explosion-proof warning light 5 provides nighttime warning, eliminating the problem of low warning effectiveness of outdoor work site warning signs in the absence of artificial lighting at night.

[0045] In this embodiment, the base 9 is a cross-shaped rod with a threaded hole 17 at its center. The bottom end of the third rod 8 is provided with an external thread that can be connected to the upper thread of the threaded hole 17, which can facilitate disassembly and retraction for transportation. The top end of the floor plug 10 is provided with a threaded rod 18 that is connected to the lower thread of the threaded hole 17, which facilitates the installation and disassembly of the floor plug 10 in different scenarios, thus making it convenient for use on both soft and hard surfaces.

[0046] In this embodiment, the base 9 has four sockets at its four ends, and four sets of brackets 12 are provided, each of which is inserted into a socket, with adjacent brackets 12 arranged perpendicularly to each other. A fourth locking screw 15 is provided on the upper side of each of the four ends of the base 9 to limit the extension length of the bracket 12, and an anti-slip pad 16 is attached to the bottom of the end of each bracket 12. When used on a softened surface, the ground plug 10 is inserted into the ground with its outer arc-shaped insert 11 for fixation, preventing the main body of the device from rotating. At this time, each bracket 12 is retracted into its socket to avoid interference caused by the bracket 12 extending and contacting the ground on a sloping surface. When used on a hardened surface, the ground plug 10 is removed, and each bracket 12 extends to its longest position, keeping the base 9 balanced when placed on the ground. The anti-slip pad 16 prevents it from sliding on a smooth surface, and heavy objects can be placed on the brackets 12 to prevent them from tipping over. By making the bracket 12 and support rod telescopic and detachable, the support rod and bracket can be folded up when carried and transported, making the overall structure more compact and minimizing space occupation, thus facilitating carrying and transportation.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
