Description

Technical Field

[0001] This utility model relates to the technical field of pole protection equipment, specifically to a pole protection warning device. Background Technology

[0002] Current utility pole anti-collision systems mostly use circumferentially installed water-filled plastic anti-collision barrels, which are usually filled with water to enhance impact resistance through liquid mass. However, this design has a significant drawback: when a full barrel is impacted, due to the incompressibility of the liquid, the impact force is directly transmitted to the barrel structure, relying solely on the barrel's deformation to absorb energy, resulting in limited cushioning effect. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a pole anti-collision warning device with good buffering effect. It is not only simple in structure, but also has the advantages of safety, reliability and low cost.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A pole anti-collision warning device includes two symmetrically arranged semi-circular cylinders. The two semi-circular cylinders are connected by a connecting structure to form a cylindrical structure that can cover the pole. Each semi-circular cylinder has a hollow chamber for storing water. A drain hole communicating with the hollow chamber is provided on the outer side of each semi-circular cylinder. A water inlet hole communicating with the hollow chamber is provided on each semi-circular cylinder above the drain hole. When the water level in the hollow chamber is level with the drain hole, if the semi-circular cylinder is impacted, the water in the hollow chamber can be quickly discharged from the drain hole and the water inlet hole, thereby releasing the impact energy. A damping material is placed in the hollow chamber. When the hollow chamber is filled with water, the damping material on the water surface of the hollow chamber forms a damping layer.

[0006] Furthermore, the drain hole is located at 1 / 2 to 4 / 5 of the total height of the hollow cavity.

[0007] Furthermore, the damping material includes an absorbent sponge suspended in water and EVA foam floating on the water surface.

[0008] Furthermore, the water inlet includes a first water inlet and a second water inlet that can also be used to place the damper within the hollow cavity.

[0009] Furthermore, the upper surface of the semi-circular cylinder is provided with a water collection trough for collecting rainwater. The bottom wall of the water collection trough is set at an inclined angle relative to the horizontal plane. The first water inlet and the second water inlet are both set in the water collection trough. The opening of the second water inlet is covered with an end cap. When the semi-circular cylinder is impacted, the water in the hollow cavity is discharged from the first water inlet and the water in the hollow cavity is flushed off the end cap on the second water inlet and discharged from the second water inlet.

[0010] Furthermore, a buffer layer is provided between the upper and lower ends of the inner side of the semi-circular cylinder and the outer surface of the pole. The material of the buffer layer is foam, rubber or silicone.

[0011] Furthermore, the outer side of the semi-circular cylinder is alternately arranged with luminous warning strips and footrest holes for climbing the pole along its axial direction.

[0012] Furthermore, a solar warning device is also provided on the upper outer side of the semi-circular cylinder. The solar warning device includes a transparent protective cover, which houses a solar panel, a lithium battery, a circuit board, and an LED display screen for displaying text information in sequence. The circuit board integrates four LED beads. The solar panel, circuit board, and LED display screen are all arranged facing the outer side of the transparent protective cover. The solar panel and circuit board are located above the LED display screen, and the lithium battery is located inside the LED display screen.

[0013] Furthermore, the connecting structure includes opening slots on both radial sides of the outer edge of the semi-arc cylinder, with the opening slots on each side spaced apart along the axial direction of the semi-arc cylinder. The opening slots are provided with locking holes. When the two semi-arc cylinders are joined together, the locking holes on the two semi-arc cylinders are aligned with each other to form a through channel. A cantilever buckle is inserted into the through channel, and the two semi-arc cylinders are combined to form a cylindrical structure through the cantilever buckle.

[0014] Furthermore, the cantilever buckle includes a base and two symmetrically arranged cantilever arms. The fixed ends of the cantilever arms are connected to the base, and the free ends of the cantilever arms extend away from the base. The two cantilever arms are arranged in a figure-eight shape, and the distance between the free ends of the two cantilever arms is greater than the distance between the fixed ends. The cantilever arms are provided with several barbs along their length. When the two semi-circular cylinders are aligned, the base of the cantilever buckle abuts against the opening groove of one of the semi-circular cylinders, and the barbs of the cantilever buckle abut against the opening groove of the other semi-circular cylinder. When the two cantilever arms are squeezed together by external force, the two cantilever arms can elastically close together, allowing the cantilever buckle to disengage from the opening groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention employs a design where the water level inside the hollow cavity is flush with the drain hole. When impacted, the impact force is transmitted to the hollow cavity, causing the water inside to violently slosh to dissipate the impact energy. Simultaneously, the water can be quickly discharged through the drain hole and inlet hole, effectively releasing the impact energy. Furthermore, the compressibility of the air inside the hollow cavity further absorbs some of the impact energy. This design significantly improves the impact resistance of the pole anti-collision warning device through the triple effects of dynamic dissipation of water, rapid discharge, and air buffering.

[0017] In addition, the hollow cavity contains damping material, which generates viscous resistance through relative movement with the water, thereby dissipating some of the impact energy and further improving the impact resistance of the pole anti-collision warning device.

[0022] The present invention will be further described in detail below with reference to the embodiments shown in the accompanying drawings.

[0023] like Figures 1 to 4 As shown in the embodiment of this utility model, a pole anti-collision warning device includes two symmetrically arranged semi-circular cylinders 1. The two semi-circular cylinders 1 are connected by a connecting structure 2 to form a cylindrical structure that can cover the pole. The semi-circular cylinder 1 has a hollow chamber 11 for storing water. A drain hole 12 communicating with the hollow chamber 11 is provided on the outer side of the semi-circular cylinder 1. A water inlet hole 13 communicating with the hollow chamber 11 is provided on the semi-circular cylinder 1 above the drain hole 12. When the water level in the hollow chamber 11 is level with the drain hole 12, if the semi-circular cylinder 1 is impacted, the water in the hollow chamber 11 can be quickly discharged from the drain hole 12 and the water inlet hole 13 to release the impact energy. The hollow chamber 11 is equipped with a damping material 14. When the hollow chamber 11 is filled with water, the damping material 14 on the water surface of the hollow chamber 11 forms a damping layer, thereby generating viscous resistance between the relative motion with the water.

[0024] As described above, the drain hole 12 is located at 1 / 2 to 4 / 5 of the total height of the hollow cavity 11. Preferably, the impact resistance of the pole anti-collision warning device is optimal when the drain hole 12 is located at 3 / 5 of the total height of the hollow cavity 11.

[0025] As described above, the damping material 14 includes an absorbent sponge suspended in the water and EVA foam floating on the water surface.

[0026] As described above, the water inlet 13 includes a first water inlet 131 and a second water inlet 132, which can also be used to place the damper 14 into the hollow cavity 11.

[0027] As described above, a water collection trough 15 for collecting rainwater is provided on the upper surface of the semi-circular cylinder 1. The bottom wall of the water collection trough 15 is set at an inclined angle relative to the horizontal plane. The first water inlet 131 and the second water inlet 132 are both set in the water collection trough 15. The opening of the second water inlet 132 is covered by an end cap 133. When the semi-circular cylinder 1 is impacted, the water in the hollow chamber 11 is discharged from the first water inlet 131 and the water in the hollow chamber 11 is flushed away from the end cap 133 on the second water inlet 132 and discharged from the second water inlet 132.

[0028] As described above, a buffer layer 16 is provided between the upper and lower ends of the inner side of the semi-circular cylinder 1 and the outer surface of the pole. The material of the buffer layer 16 is foam, rubber or silicone, which helps to reduce the impact force and further protect the pole.

[0029] As described above, the outer side of the semi-circular cylinder 1 is alternately arranged with luminous warning strips 17 along its axial direction, which can reflect light in dark or low light environments, thereby making the outline of the pole more obvious and reducing the risk of accidental touch or collision; and foothold holes 18 for climbing the pole, providing power maintenance personnel with a stable climbing support point, enabling them to safely and efficiently climb the pole.

[0030] As described above, a solar-powered warning device 19 is also provided on the upper outer side of the semi-circular cylindrical body 1. The solar-powered warning device 19 includes a transparent protective cover 191. The transparent protective cover 191 houses a solar panel 192, a lithium battery 193, a circuit board 194, and an LED display screen 195 for displaying text information, which are connected in sequence. The circuit board 194 integrates four LED beads 196. The solar panel 192, the circuit board 194, and the LED display screen 195 are all arranged facing the outer side of the transparent protective cover 191. The solar panel 192 and the circuit board 194 are located above the LED display screen 195, and the lithium battery 193 is located inside the LED display screen 195. At night, under normal conditions, the four LED beads 196 on the circuit board 194 flash. When an object is detected approaching, the LED display screen 195 displays warning content, and the four LED beads 196 stop flashing. This effectively reminds the driver to pay attention to the road, making up for the passivity of traditional warning signs and proactively preventing potential driving hazards.

[0031] As described above, the connecting structure 2 includes opening slots 21 on both radial sides of the outer edge of the semi-arc cylindrical body 1. The opening slots 21 on each side are arranged at intervals along the axial direction of the semi-arc cylindrical body 1, and the opening slots 21 are provided with locking holes 22. When the two semi-arc cylindrical bodies 1 are joined together, the locking holes 22 on the two semi-arc cylindrical bodies 1 are aligned with each other and form a through channel 23. A cantilever buckle 24 is inserted into the through channel 23, and the two semi-arc cylindrical bodies 1 are combined to form a cylindrical structure through the cantilever buckle 24.

[0032] As described above, the cantilever buckle 24 includes a base 241 and two symmetrically arranged cantilever arms 242. The fixed ends of the cantilever arms 242 are connected to the base 241, and the free ends of the cantilever arms 242 extend away from the base 241. The two cantilever arms 242 are arranged in a figure-eight shape, and the distance between the free ends of the two cantilever arms 242 is greater than the distance between the fixed ends. The cantilever arms 242 are provided with a number of barbs 243 along their length. When the two semi-circular cylinders 1 are aligned, the base 241 on the cantilever arm 242 buckle abuts against the opening groove 21 of one of the semi-circular cylinders 1, and the barbs 243 on the cantilever arm 242 buckle abut against the opening groove 21 of the other semi-circular cylinder 1. When the two cantilever arms 242 are pinched together by external force, the two cantilever arms 242 can elastically close together, so that the cantilever buckle 24 can disengage from the opening groove 21.

[0033] During installation, simply align the two semi-circular cylinders 1 and form a through channel 23 through the holes 22 on the two semi-circular cylinders 1. Insert the cantilever buckle 24 into the through channel 23 to complete the installation of the pole anti-collision warning device. During disassembly, simply pinch the two cantilever arms 242 on the cantilever buckle 24 and remove them from the through channel 23 to disassemble the pole anti-collision warning device. Therefore, no auxiliary tools are required to complete the quick installation and disassembly of the pole anti-collision warning device, which has the advantages of simple structure and low cost.

[0034] The above description is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Any simple equivalent changes and modifications made in accordance with the scope of the present utility model patent application and the description of the utility model shall still fall within the scope of the present utility model patent.
