Description

Technical Field

[0001] This invention relates to a guardrail, and more particularly to an expandable polygonal safety warning fence device. Background Technology

[0002] In scenarios such as power maintenance, road construction, equipment maintenance, and large-scale event site management, it is usually necessary to set up safety warning fences to effectively isolate the work area from the non-work area, prevent unauthorized personnel from accidentally entering the dangerous area, and thus ensure personnel safety.

[0003] Existing safety warning fences mostly adopt a fixed-length straight structure, forming an enclosed area by connecting several fence units end to end. Their structure is relatively simple and mainly suitable for regular, straight-line site environments. However, in actual applications, work sites often have irregular or complex terrain such as transformer perimeters, road corners, bridge piers, and slope construction areas. Existing straight safety fences are difficult to deploy flexibly according to the site shape, and the enclosure angle is not adjustable, often requiring multiple adjustments or temporary splicing. Even so, it is still difficult to form an effective enclosure structure that fits the site contours, affecting the safety warning effect. Furthermore, irregular or complex terrain also limits the installation of the fence base on site; the overall installation adaptability of the fence is too poor, and it is inconvenient to deploy and retract. Summary of the Invention

[0004] The technical problem to be solved by this invention is: how to make the installation of the fence on the work site more flexible, improve the fence's adaptability to the site environment, and make it easy to deploy and retract.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: An expandable polygonal safety warning fence device includes: A fencing assembly, wherein connectors are provided on both the right and left sides of the fencing assembly; A column assembly having an annular mounting member arranged along a circumferential side, the annular mounting member being detachably connected to a connector of at least one of the enclosure assemblies, the position of the connector on the annular mounting member being adjustable in a direction surrounding the column assembly; The support bases, at least two and different, have different connection types to the ground, and the support bases are detachably connected to the column assembly.

[0006] The beneficial effects of this invention are as follows: It provides an expandable polygonal safety warning fence device, which consists of a column assembly, a fence assembly, and a support base. Multiple column assemblies and fence assemblies are arranged alternately to form a fence. During connection, the relative rotatable connection between the ring-shaped mounting parts and the connecting parts allows for multi-angle adjustment, making the shape of the fence more flexible to cope with irregular or complex terrain. At the same time, the use of support bases with different connection types ensures that the fence remains stable on irregular or complex terrain. Relying on the detachable connection between the ring-shaped mounting parts and the connecting parts, as well as between the column assembly and the support base, the fence is easy to put on and take off, improving the fence's adaptability to the site environment.

[0009] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0010] Existing safety warning fences mostly adopt a fixed-length straight structure, with several fence units connected end to end to form an enclosed area. Their structure is relatively simple and mainly suitable for regular, straight site environments. However, in actual applications, work sites often have irregular or complex terrain, such as around transformers, road corners, bridge piers, and slope construction areas. Specific examples are as follows: I. Fencing around power equipment such as transformers, ring main units, and distribution boxes. Transformer platforms, prefabricated substations, and ring main units are often arranged in square, rectangular, or polygonal shapes. Their foundations typically include steps, slopes, and foundation platforms. Cable trenches, grounding electrodes, and operating access routes may also be present nearby. Straight-line fencing can only be rigidly assembled and cannot conform to the equipment's outline to create a polygonal enclosure. This can easily lead to excessively large gaps in the fencing, blind spots, interference between the fencing and the equipment, or difficulties in close proximity.

[0011] II. The protective area at the base of transmission line towers and utility poles: The tower foundations are mostly stepped or conical platforms, often surrounded by slopes, drainage ditches, guy wire pits, grounding devices, etc., resulting in uneven terrain. Straight-line fences are difficult to form a closed ring around the tower, and the fixed angle leads to uneven gaps between the fence and the tower, which affects both the warning effect and the determination of a safe working radius.

[0012] 3. Cable trenches around the openings of power conduits, cable wells, and cable tunnels are often a combination of straight lines and corners, with well openings typically being circular, square, or rectangular. The surrounding ground often experiences settlement, slope, and protruding manhole covers. Straight-line fencing cannot flexibly follow the direction of the trench, and when enclosing the well opening, problems such as sharp corners hanging in the air and loose joints easily occur, failing to form a continuous and enclosed safety warning zone.

[0013] In response, existing straight safety fences are difficult to deploy flexibly according to the shape of the site, and the enclosure angle is not adjustable. They often need to be adjusted or temporarily spliced ​​multiple times, and it is still difficult to form an effective enclosure structure that fits the outline of the site, thus affecting the safety warning effect.

[0014] To solve at least the above problems, such as Figures 1 to 5 As shown, the present invention proposes an expandable polygonal safety warning fence device, comprising: The enclosure assembly 2 is provided with connectors 5 on both its right and left sides; The column assembly 1 has an annular mounting member 4 arranged along the circumferential side, the annular mounting member 4 being detachably connected to at least one of the connecting members 5 of the enclosure assembly 2, and the position of the connecting member 5 on the annular mounting member 4 being adjustable in the direction surrounding the column assembly 1. The support base 3, at least two and different, has different connection types with the ground, and the support base 3 is detachably connected to the column assembly 1.

[0015] As described above, the fence device of the present invention consists of a column assembly 1, a barrier assembly 2, and a support base 3. Multiple column assemblies 1 and barrier assemblies 2 are arranged alternately to form a fence. During connection, the relative rotatable connection between the annular mounting piece 4 and the connecting piece 5 allows for multi-angle adjustment, making the shape of the fence more flexible to cope with irregular or complex terrain. At the same time, the use of support bases 3 with different connection types ensures that the fence remains stable on irregular or complex terrain. Relying on the detachable connection between the annular mounting piece 4 and the connecting piece 5, as well as between the column assembly 1 and the support base 3, the fence is easy to put on and take off, improving the fence's adaptability to the site environment.

[0016] Furthermore, at least two fixing parts 41 are distributed around the circumferential side of the annular mounting member 4; The connector 5 is detachably connected to any of the fixing parts 41.

[0017] As described above, by setting multiple fixing parts 41 around the annular mounting part 4, the connecting part 5 can be reliably connected to the corresponding fixing part 41 after being adjusted to a suitable angle around the column, thereby achieving the positioning and locking of the angle of the fence component 2, preventing the fence from accidentally deflecting or loosening during use, ensuring the stability of the fence enclosure shape, and improving the reliability of the overall structure and the warning and protection effect.

[0018] Furthermore, the annular mounting component 4 is provided with a rotating groove 42 surrounding the column assembly 1; The connector 5 is adjustablely positioned on the rotating groove 42.

[0019] As can be seen from the above description, the rotating groove 42 can provide a continuous and limited circumferential motion track for the connector 5, so that the connector 5 can be smoothly and steadily adjusted along the column, ensuring that the rotation adjustment process of the enclosure assembly 2 is smooth and without jamming.

[0020] Furthermore, the different support bases 3 include foot-supported bases 31 and anchored bases 32.

[0021] As can be seen from the above description, by setting at least two support bases 3 with different structures and connection methods, the column assembly 1 can flexibly select the appropriate base type according to the site ground conditions, so as to meet the installation and fixing requirements of different working conditions such as hard ground and soil ground.

[0022] Furthermore, the foot-supported base 31 includes a first adapter 311 and at least two support feet 312; The upper end of the first adapter 311 is detachably connected to the bottom of the column assembly 1; One end of the support foot 312 is rotatably disposed at the lower end of the first adapter 311, and the other end of the support foot 312 is used to press against the ground.

[0023] As described above, the rotatable support foot 312 and the first adapter 311 are used to form a foot-supported base 31, which can flexibly adjust the support angle and support range according to the flatness of the ground, and achieve stable support without damaging the ground. At the same time, the detachable structure facilitates quick assembly and storage.

[0024] Furthermore, the anchoring base 32 includes a second adapter 321 and a plug 322; The upper end of the second adapter 321 is detachably connected to the bottom of the column assembly 1; The lower end of the second adapter 321 is connected to the plug 322.

[0025] As described above, the column assembly 1 is connected to the insertion rod 322 by the second adapter 321, and the insertion rod 322 can be inserted into the ground to achieve anchoring and fixation.

[0026] Furthermore, the column assembly 1 includes a column body 11; The annular mounting component 4 is sleeved on the column body 11, and the position of the annular mounting component 4 is adjustable up and down.

[0027] As described above, the ring-shaped mounting component 4 can be adjusted up and down along the column body 11 to accommodate enclosure components 2 of different heights and sizes.

[0028] Furthermore, the enclosure assembly 2 includes a crossbar 21 and a warning sign 22; The warning sign 22 is hung on the crossbar 21, and the crossbar 21 is provided with the connector 5 at both ends; The connectors 5 at both ends of the crossbar 21 are detachably connected to the annular mounting parts 4 of one of the column assemblies 1.

[0029] As can be seen from the above description, the combination structure of using the horizontal bar 21 to suspend the warning sign 22 not only facilitates the replacement, disassembly and maintenance of the warning sign 22, but also enables the quick connection between the enclosure component 2 and the column component 1 through the connectors 5 at both ends of the horizontal bar 21.

[0030] Furthermore, there are at least two crossbars 21; The number of the annular mounting pieces 4 on one of the column assemblies 1 is the same as the number of the crossbars 21 on one of the enclosure assemblies 2.

[0031] As can be seen from the above description, by connecting multiple horizontal bars 21 with a corresponding number of ring-shaped mounting parts 4, multi-point stable support can be formed for the enclosure assembly 2.

[0032] Furthermore, the end of the crossbar 21 is rotatably connected to the connector 5.

[0033] As can be seen from the above description, the crossbar 21 and the connecting piece 5 adopt a rotating connection structure, which allows the crossbar 21 to freely deflect at a certain angle relative to the connecting piece 5, further expanding the angle adjustment range of the enclosure assembly 2.

[0034] Please refer to Figures 1 to 5 The first embodiment of the present invention is as follows: An expandable polygonal safety warning fence device includes: The enclosure assembly 2 is provided with connectors 5 on both its right and left sides; The column assembly 1 has an annular mounting member 4 arranged along the circumferential side, the annular mounting member 4 being detachably connected to at least one of the connecting members 5 of the enclosure assembly 2, and the position of the connecting member 5 on the annular mounting member 4 being adjustable in the direction surrounding the column assembly 1. The support base 3, at least two and different, has different connection types with the ground, and the support base 3 is detachably connected to the column assembly 1.

[0035] Combination Figure 1 , Figure 2 and Figure 4 As shown, the extended polygonal safety warning fence device of the present invention is detachably assembled from multiple column assemblies 1, multiple enclosure assemblies 2, and multiple support bases 3. During assembly, the annular mounting pieces 4 on the column assemblies 1 are detachably connected to the connecting pieces 5 on one of the enclosure assemblies 2. By adjusting the position of the connecting pieces 5 relative to the annular mounting pieces 4, the enclosure assemblies 2 can be rotated relative to the column body 11, changing the orientation of the enclosure assemblies 2 and the angle between the enclosure assemblies 2 on both sides of the column assemblies 1.

[0036] When the enclosure component 2 rotates relative to the column body 11, the position of the column component 1 connected to the other side of the enclosure component 2 changes. To ensure that it can be installed and fixed in different positions within the working environment, this invention provides support bases 3 with different connection types to the ground. The connection types between the support base 3 and the ground include, but are not limited to, foot-supported connection, anchored connection, suction cup connection, clamping connection, and spiral pile connection. Thus, different support bases 3 have different structures, evolving into foot-supported bases 31, anchored bases 32, etc.

[0037] For hardened roads, squares, rooftops, indoor spaces, and sites where drilling / piling is not possible, foot-supported or suction cup connections can be used. For outdoor areas, farmland, green belts, and areas with soft soil, anchored or helical pile connections can be used.

[0038] like Figure 3 and Figure 5 As shown, to ensure the stability of the enclosure assembly 2 after rotation relative to the column assembly 1, at least two fixing parts 41 are distributed on the circumferential side of the annular mounting member 4; the connector 5 is detachably connected to any of the fixing parts 41. After determining the final position, the connector 5 is connected to the fixing part 41 to fix the enclosure assembly 2. As a preferred design, the circumferential side of the annular mounting member 4 can be provided with multiple holes as fixing parts 41, and a pin is provided on the connector 5, which is used to fix the connector 5 by cooperating with the holes. The connector 5 can also be provided with a clearance groove, which can expose at least one hole to facilitate the insertion of the pin into the hole.

[0039] like Figure 3 As shown, the annular mounting component 4 is provided with a rotating groove 42 surrounding the column assembly 1; the connector 5 is adjustablely positioned on the rotating groove 42. This design can limit the movement trajectory of the connector 5, so that the fence assembly 2 can only rotate smoothly along the circumference of the column, avoiding swaying, displacement or falling off, and ensuring the overall structural stability of the fence.

[0040] In some embodiments, such as Figure 2 and Figure 3 As shown, the column assembly 1 includes a column body 11; an annular mounting member 4 is sleeved on the column body 11, and the position of the annular mounting member 4 is adjustable vertically to accommodate enclosure assemblies 2 of different sizes. Specifically, the annular mounting member 4 is a hollow cylindrical structure, the inner diameter of which matches the outer diameter of the column body 11, and the annular mounting member 4 is detachably sleeved on the outside of the column body 11. Furthermore, at least two annular mounting members 4 can be selected to jointly fix one enclosure assembly 2 on one side of the column assembly 1.

[0041] In some embodiments, such as Figure 4As shown, the foot-supported base 31 includes a first adapter 311 and at least two support legs 312. The upper end of the first adapter 311 is detachably connected to the bottom of the column assembly 1. One end of each support leg 312 is rotatably disposed at the lower end of the first adapter 311, and the other end of the support leg 312 is used to press against the ground. The foot-supported base 31 can be divided into two-legged, three-legged, and other support forms depending on the number of support legs 312. Therefore, the support legs 312 can flexibly adjust their deployment angle and support range according to the ground conditions, adapting to working environments such as cement roads and hardened sites where piling and anchoring are inconvenient. At the same time, the configuration of different numbers of support legs 312, such as two-legged and three-legged, balances storage convenience and support stability.

[0042] In some embodiments, such as Figure 2 As shown, the anchoring base 32 includes a second adapter 321 and a plug rod 322; the upper end of the second adapter 321 is detachably connected to the bottom of the column assembly 1; the lower end of the second adapter 321 is connected to the plug rod 322. When the fence is installed, the tapered plug rod 322 is inserted into the ground to complete the fixation.

[0043] In some embodiments, such as Figure 2 As shown, the fencing component 2 includes a horizontal bar 21 and warning signs 22; the warning signs 22 are hung on the horizontal bar 21, and each end of the horizontal bar 21 is provided with a connector 5; the connectors 5 at both ends of the horizontal bar 21 are detachably connected to the annular mounting parts 4 of a column component 1. The warning signs 22 include, but are not limited to, commonly used fencing structures such as mesh, warning tape, and signs.

[0044] Furthermore, there are at least two crossbars 21; the number of annular mounting pieces 4 on one column assembly 1 is the same as the number of crossbars 21 on one enclosure assembly 2. To improve the angle adjustment range, the ends of the crossbars 21 are rotatably connected to the connectors 5, such as ball joints.

[0045] In summary, this invention discloses an expandable polygonal safety warning fence device, mainly composed of a fence assembly, a column assembly, and various types of support bases that can be detachably assembled. The fence assembly has connectors on both sides, and the column assembly has circumferentially arranged and height-adjustable annular mounting parts. The connectors can be adjusted circumferentially along the rotating groove of the annular mounting parts and locked in place by a fixing part. The bottom of the column assembly can be adapted to different support bases such as foot-supported bases, anchored bases, suction cup bases, clamping bases, and spiral pile bases. The fence assembly adopts a structure with multiple horizontal bars suspending warning signs, and the ends of the horizontal bars are rotatably connected to the connectors to increase the angle adjustment range. This device achieves flexible changes in the fence angle through the circumferentially adjustable structure of the fence assembly around the columns, allowing for continuous enclosure of irregular power operation scenarios such as transformers, towers, cable wells, and road corners. Simultaneously, it relies on various support bases adapted to different ground surfaces to ensure installation stability in complex terrains. The overall assembly and disassembly are convenient, and the device significantly improves the adaptability and safety protection effect of the safety warning fence to complex on-site environments.

[0046] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention.
