Description

Technical Field

[0001] This utility model relates to the field of wire harness safety protection technology, specifically a wire harness safety protection structure. Background Technology

[0002] In temporary or permanent cable laying scenarios for power, telecommunications, and municipal engineering projects, cable trays (also known as cable protectors or road crossing guards) are crucial devices for protecting cables crossing roads and sites from vehicle crushing, mechanical impact, and environmental corrosion. Their core function is to provide robust physical protection and reliable environmental sealing to ensure the safe and stable operation of cables. Traditional cable trays are mostly rigid structures, forming a closed channel by clips or bolts between the top cover and the base. However, when the cables running inside have varying diameters, quantities, or joints, irregular gaps can form between the cables and the inner wall of the cable tray. External contaminants such as water, mud, and dust can easily penetrate through these gaps, corroding the cable joint insulation and causing faults such as short circuits and signal attenuation. This is especially true in humid, dusty, or rainy environments, where the likelihood of such problems increases significantly. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a wire harness safety protection structure, which solves the problems mentioned in the background section.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wire harness safety protection structure comprising several wire groove sections, wherein the several wire groove sections form a wire groove, each wire groove section being composed of an upper cover and a base, the top of the base having several placement cavities, each placement cavity having a lower fixing seat embedded inside, each lower fixing seat having a lower airbag embedded in its inner wall, the bottom of the upper cover being fixedly connected to a limit strip located inside the placement cavity, the bottom of each limit strip being fixedly connected to an upper fixing seat, each upper fixing seat having an upper airbag embedded in its inner wall.

[0005] Preferably, each of the two bases on the first and last ends of the wire trough has an insertion hole. A main pipe is fixedly connected inside each insertion hole. Several first threaded end seats are fixedly connected to the outside of the main pipe. A flexible tube is fixedly connected to the front surface of each upper fixed seat. A first rotary joint is installed at one end of each flexible tube. A first threaded end is installed at one end of each first rotary joint. One end of each first threaded end extends into the interior of the first threaded end seat and is threadedly connected to the interior of the first threaded end seat.

[0006] Preferably, a manually operated butterfly valve is fixedly connected to the outside of the main pipe, a second threaded end seat is fixedly connected to one end of the manually operated butterfly valve, a second threaded end head is threadedly connected inside the second threaded end seat, a discharge end is fixedly connected to one end of the second threaded end head, and a piston cylinder is fixedly connected to one end of the discharge end.

[0011] This utility model provides a wire harness safety protection structure, which has the following beneficial effects:

[0012] 1. This wire harness safety protection structure includes a placement chamber, a lower fixed seat, and an upper fixed seat. By pulling the piston rod, outside air is drawn into the piston cylinder through the intake end. This pushes the piston rod further into the piston cylinder, causing the air inside the piston cylinder to enter the second threaded end through the exhaust end. From there, the air enters the second threaded end seat, the opened manual switch butterfly valve, and the main pipe. From the main pipe, the air enters the lower fixed seat, while another portion of the air enters the upper air bladder through the first threaded end seat, the first threaded end, the first rotary joint, and the hose. This causes the upper and lower air bladders to inflate, sealing them together and conforming to the outer side of cables of various diameters. This effectively prevents mud, sand, and water from entering. The base and top cover also provide pressure protection for the cables.

[0013] 2. The safety protection structure of this wire harness is provided with a first threaded end seat, a first threaded end and a hose. One end of the first threaded end is taken out from inside the first threaded end seat, and the main pipe and the hose are separated so that the top cover can be removed from the top of the base, so that the upper fixing seat, the upper airbag and the limiting strip can be removed from the inside of the placement cavity, and the cable inside the placement cavity can be taken out.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a wire harness safety protection structure, including several wire groove sections, and the several wire groove sections form a wire groove. Each wire groove section is composed of an upper cover 2 and a base 1. The top of the base 1 has several placement cavities 3. Each placement cavity 3 is inlaid with a lower fixing seat 4. The inner wall of the lower fixing seat 4 is inlaid with a lower airbag 5. The bottom of the upper cover 2 and located inside the placement cavity 3 is fixedly connected to a limit strip 8. The bottom of the limit strip 8 is fixedly connected to an upper fixing seat 6. The inner wall of the upper fixing seat 6 is inlaid with an upper airbag 7. The upper fixing seat 6 and the lower fixing seat 4 form a complete ring, and the upper airbag 7 and the lower airbag 5 form a complete ring.

[0021] The first and last ends of the cable trays each have an insertion hole 23 at one end of the base 1. A main pipe 10 is fixedly connected inside the insertion hole 23. Several first threaded end seats 11 are fixedly connected to the outside of the main pipe 10. A flexible hose 9 is fixedly connected to the front surface of each fixed base 6. A first rotary joint 12 is installed at one end of each flexible hose 9. A first threaded end 14 is installed at one end of each first rotary joint 12. One end of each first threaded end 14 extends into the first threaded end seat 11 and is threadedly connected to the inside of the first threaded end seat 11. When the cable needs to be removed, the manual switch butterfly valve 15 is opened, so that the gas inside the upper airbag 7 enters the main pipe 10 through the flexible hose 9, the first rotary joint 12, the first threaded end 14, and the first threaded end seat 11. The gas inside the lower airbag 5 enters the main pipe 10 and is discharged through the manual switch butterfly valve 15 and the second threaded end seat 16.

[0022] A manual switch butterfly valve 15 is fixedly connected to the outside of the main pipe 10. A second threaded end seat 16 is fixedly connected to one end of the manual switch butterfly valve 15. A second threaded end head 20 is threadedly connected inside the second threaded end seat 16. A discharge end 19 is fixedly connected to one end of the second threaded end head 20. A piston cylinder 17 is fixedly connected to one end of the discharge end 19. Take one end of the first threaded end head 14 out from inside the first threaded end seat 11 to separate the main pipe 10 from the hose 9.

[0023] A piston rod 13 is slidably connected inside the piston cylinder 17. One end of the piston rod 13 extends to the outside of the piston cylinder 17. An air intake end 21 is fixedly connected to the bottom of the piston cylinder 17. The bolt 22 is removed from the inside of the base 1, and then the upper cover 2 is removed from the top of the base 1, so that the upper fixed seat 6, the upper airbag 7 and the limiting strip 8 are removed from the inside of the placement cavity 3, and the cable inside the placement cavity 3 is taken out.

[0024] Both the discharge end 19 and the intake end 21 extend into the piston cylinder 17 and are equipped with one-way valves. Through the one-way valves, gas is drawn into the piston cylinder 17 through the intake end 21 and discharged into the second threaded end 20 through the discharge end 19.

[0025] A pressure gauge 18 is fixedly connected to the surface of the discharge end 19. The detection end of the pressure gauge 18 extends into the discharge end 19 to check the pressure value in the circuit.

[0026] One end of the hose 9 extends into the interior of the upper airbag 7, and the other end of the main pipe 10 extends into the interior of the lower airbag 5. The upper cover 2 is fixed to the base 1 by bolts 22. Several insertion holes 23 are provided on both ends of the base 1. The base 1 is fixed to the ground by anchors and other fixing devices through the insertion holes 23.

[0027] In summary, the safety protection structure for this wire harness is used as follows: The base 1 of the wire trough section is laid on the ground, the cable is placed into the placement cavity 3, and the top cover 2 is placed on top of the base 1, allowing the limiting strip 8 and the upper fixing seat 6 to be placed into the placement cavity 3. The top cover 2 is then installed on the base 1 using bolts 22. Next, one end of the first threaded end 14 is screwed into the first threaded end seat 11, and the piston cylinder 17 is removed. Then, one end of the second threaded end 20 is screwed into the second threaded end seat 16. By pulling the piston rod 13, outside air is drawn into the piston cylinder 17 through the suction end 21, pushing the piston rod 13 further into the piston cylinder 17, thus allowing air to pass through the piston cylinder 17. Air enters the second threaded end 20 through the exhaust end 19, then enters the second threaded end seat 16, the open manual switch butterfly valve 15, and the main pipe 10 through the second threaded end 20. Then, it enters the lower fixed seat 4 through one end of the main pipe 10. Another part of the air enters the upper airbag 7 through the first threaded end seat 11, the first threaded end 14, the first rotary joint 12, and the hose 9, causing the upper airbag 7 and the lower airbag 5 to inflate and seal between them. This seals the outer side of cables of various diameters, effectively preventing mud, sand, and water from entering and achieving a seal. Then, the manual switch butterfly valve 15 is closed, and the second threaded end 20 is unscrewed from the second threaded end seat 16.
