Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary facilities for laying wires, cables and other wires, and in particular to a cable overhead protection device. Background Technology

[0002] At construction sites, temporary power lines and cables are sometimes laid as needed. When these cables need to cross roads, if the roadbed conditions permit, a simpler method can be chosen, such as digging a trench on the roadbed to cross the road, laying the cable along the trench, and then backfilling it. This way, the cable remains within the trench during use, avoiding repeated vehicle traffic and protecting it. However, when roadbed conditions do not permit, such as on mountain roads where trenches are difficult to construct, or where asphalt or concrete roads cannot be damaged, the cable needs to be elevated to allow it to cross the road and for vehicles to pass underneath it, thus protecting the cable. Currently, the method used to elevate cables is to install a support on each side of the road, supporting the cable on the support to achieve the crossing. While this method is relatively simple, the cables are prone to sag due to their own weight at the midpoint between the two supports, above the middle of the road surface. This is especially noticeable when spanning wider sections of the road. When trucks carrying large loads or tall vehicles pass by, they can easily scrape or pull on the cables, potentially causing damage or even breakage. This not only affects the normal use of the cables but also creates safety hazards. Furthermore, damage to the overhead cable system cannot be detected and repaired promptly. Therefore, improvements and optimizations to the overhead cable system are necessary. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a cable elevation protection device that can prevent cables from drooping above the road, completely eliminate the possibility of being scratched by vehicles, and can be maintained in time after being hit.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a cable elevation protection device, comprising two roadbed boxes arranged opposite each other, with elevation poles detachably installed on the top of each of the two roadbed boxes, and the tops of the two elevation poles detachably connected to the cable box. The cable box and the two elevation poles are arranged in a gate shape. Cable through holes are provided on the side walls of the cable box to facilitate cable passage.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the cable overhead protection device is installed across the road, allowing power lines and cables to be elevated and laid horizontally above the road surface, ensuring safe cable installation. It is particularly suitable for locations where it is impossible to create trenches for cable laying on the road surface. Specifically, it includes two roadbed boxes positioned opposite each other, fixed to both sides of the road to form the base of the entire device for support and fixation. Each roadbed box includes a box body 1, with a box body mounting plate 2 fixedly connected to its bottom. The box body 1 is secured to the foundation using anchor bolts that engage with the box body mounting plate 2.

[0022] Each of the two roadbed boxes has a detachable support pole 3 mounted on its top. The tops of the two support poles 3 are detachably connected to a cable box 4. The cable box 4 and the two support poles 3 are arranged in a portal shape. Cable through-holes 5 are provided on both side panels of the cable box 4 to facilitate cable passage. The support poles 3 can be configured as electrically telescopic poles, allowing for adjustment to ensure the safe passage of oversized vehicles. Cables pass through the two cable through-holes 5 into the cable box 4. Cables directly above the road surface are stored inside the cable box 4 to prevent them from being dragged by taller vehicles due to gravity, thus maximizing cable protection. In this embodiment, the top plate of the cable box 4 is detachable for easy viewing and organization of the internal wiring. Furthermore, a cable routing plate 6 is installed on the inner wall of the cable box 4, and a branching notch 7 is formed through the cable routing plate 6. When there are many cables to be installed, they can be routed separately through the branching notch 7 and supported by the cable routing plate 6 to prevent the cables inside the box from getting tangled together due to the large number of cables, and to facilitate the removal of cables when some cables are used up.

[0023] In this embodiment, elevated warning devices are respectively provided on the outer surfaces of the front and rear wall panels of the cable box 4 to provide long-distance indication of the position of the entire device, so that the driver can adjust the vehicle in advance to ensure safe passage. Specifically, the elevated warning device includes a warning light 8 fixedly installed on the surface of the cable box 4, and a warning sign 9 is provided around the warning light 8 on the surface of the cable box 4. The warning light 8 can be set as a light strip along the cable box 4, or multiple lights can be arranged linearly or in an array. The warning sign 9 is a reflective sign, and its brightness can be appropriately enhanced under the illumination of the warning light 8, vehicle headlights, or sunlight to highlight and enhance the warning effect.

[0024] Impact buffer devices are respectively installed at both ends of the roadbed box, and at least one of the roadbed boxes encapsulates an impact alarm device triggered by the impact buffer device. A hollow mounting cavity 10 is formed inside the box 1, and the impact alarm device is located in the mounting cavity 10, making the external structure relatively regular. The roadbed box has a mounting recess 11, and the impact buffer device is movably mounted in the mounting recess 11. When a vehicle collides with the impact buffer device with a small force, the impact buffer device can provide a certain buffering effect; when the impact force is large enough to trigger the impact alarm device, the impact alarm device is activated by the action of the impact buffer device, triggering an alarm to remind relevant personnel to check and maintain the equipment in a timely manner. A camera can also be installed on the cable box 4 to collect images of passing vehicles, so as to view the incident and information about the vehicles involved in the accident after an unexpected collision. The impact alarm device can be installed separately for each of the two roadbed boxes, or the two roadbed boxes can share a single impact alarm device to reduce the cost of equipment.

[0025] The impact buffer device includes an impact buffer plate 12 located outside the roadbed box. A buffer guide block 13 is fixedly connected to the side of the impact buffer plate 12 facing the roadbed box. The buffer guide block 13 corresponds to the mounting recess 11, and partially extends into the mounting recess 11. A buffer guide rod 14 is arranged and connected to the buffer guide block 13. The buffer guide rod 14 passes through the mounting recess 11 and engages with the roadbed box for a limiting insertion. An impact buffer spring 15 is fitted onto the buffer guide rod 14 located within the mounting recess 11. When a vehicle contacts the impact buffer plate 12, the impact buffer plate 12 drives the buffer guide block 13 and the buffer guide rod 14 to move synchronously towards the roadbed box, simultaneously compressing the impact buffer spring 15 to provide a certain buffering effect. Impact buffer blocks 16, generally made of rubber, can also be arranged on the surface of the impact buffer plate 12 to buffer impacts and protect the impact buffer plate 12.

[0026] The impact alarm device includes a pressure sensor 17 located within the mounting recess 11 corresponding to the impact buffer device, and an alarm controller 18 located within the roadbed box. The pressure sensor 17 is connected to the alarm controller 18, which is also connected to a battery 19 and a communication module 20. The communication module 20 is connected to a remote alarm device, such as a smartphone or office computer used by maintenance personnel, to remotely alarm in the event of an impact accident. Specifically, when the impact buffer plate 12 is subjected to a large impact, it will displace to its maximum travel until it touches the pressure sensor 17. Once the detection value of the pressure sensor 17 reaches the alarm trigger setting, the alarm controller 18 will trigger an alarm through the communication module 20 and the remote alarm device.

[0027] The impact alarm device also includes an alarm light 21 and / or a buzzer fixed to the outside of the roadbed box. The alarm light 21 and / or the buzzer are connected to the alarm controller 18 to provide on-site alarm in the event of a collision, alerting nearby construction personnel and warning passing vehicles to proceed with caution. Additionally, rubber anti-scratch plates 22 can be fixedly affixed to the opposite surfaces of the two roadbed boxes to protect them from scratches and passing vehicles.

[0028] The description of this utility model is given for illustrative and descriptive purposes only, and is not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the utility model, and to enable those skilled in the art to understand the utility model and design various embodiments with various modifications suitable for a particular purpose.
