[0004] Existing methods of walking on the ground and their shortcomings:

[0005] 1. The ground is destroyed and pits are dug, and the cables are buried or buried in pipes, which destroys the original road surface and affects the traffic during the destruction and restoration of the road surface.

[0006] 2. Use wood and other non-hard materials as protective shelters around the cables and cross the road from the road surface. The weighing capacity is limited and the shelters are easily crushed by passing vehicles and cannot protect the cables.

[0007] 3. Place the cable in an iron pipe and place it on the road across the road. The iron pipe and the cables inside the pipe will move on the ground with the passing vehicles. The iron pipe will be flattened or deformed by the vehicles, affecting the safety of electricity use.

[0008] Therefore, a crossing line protection device is needed to solve the above technical problems. Utility Model Content

[0009] The problem to be solved by the utility model is to provide a crossing road protection device. On the basis of not damaging the road surface, the cable is placed in the protection device, will not move on the ground with the passing vehicles, and can reasonably disperse the vehicle pressure and will not be crushed by the vehicles.

[0010] In order to solve the above technical problems, the technical solution adopted by the utility model is: a crossing line protection device, which can be used to protect cables, including a base, a protective tube movably connected to the base, and a support member arranged between the base and the protective tube. The cable can be placed in a protective cavity formed by the base and the protective tube.

[0011] Furthermore, the base is connected to the protective tube via a connecting piece, and the connecting piece includes a matching protrusion and a recessed portion to achieve radial limitation of the base and the protective tube.

[0012] Furthermore, the recessed portion has a circular inner surface, and the raised portion has a circular outer surface, so that the raised portion is in close contact with the recessed portion.

[0013] Furthermore, the protection tube is provided with a first recessed portion, and the base is provided with a second raised portion, and the second raised portion can be inserted into the first recessed portion and drive the protection tube to move along the length direction of the first recessed portion.

[0014] Furthermore, the first recessed portion is provided on a side of the protective tube close to the cable.

[0015] Furthermore, the protection tube is provided with a first protrusion, and the base is provided with a second recess. The first protrusion can be inserted into the second recess and drive the protection tube to move along the length direction of the second recess.

[0016] Furthermore, adjacent end surfaces of the protective tubes that are close to each other are respectively provided with a third protrusion and a third recessed portion for accommodating the third protrusion, so as to achieve axial limitation of the protective tube.

[0017] Furthermore, the cross section of the protection tube is arc-shaped.

[0018] Furthermore, the protection tube is provided with an extension plate to increase the contact area between the device and the ground.

[0019] Furthermore, the plurality of support members are symmetrically distributed on both sides of the cable to disperse the pressure.

[0031] The technical solution adopted by the utility model is: Figure 1 and Figure 2 As shown, a crossing line protection device for protecting cables comprises a base 2, a protective tube 1 slidably connected to the base 2, and a support member 3 disposed between the base 2 and the protective tube 1. The cables can be placed within the protective cavity formed by the base 2 and the protective tube 1. In this embodiment, the lower portion of the base 2 contacts the ground, and the protective tube 1 is placed above the base 2. The base 2 and the protective tube 1 enclose a protective cavity, with multiple interconnected protective cavities. The cables pass through the middle of the support member 3 to protect them from damage. The support member 3 is disposed within the protective cavity, stably supporting the base 2 and the protective tube 1. When placed within the protection device, the cables will not move on the ground with passing vehicles, and the pressure from vehicles will be effectively distributed, preventing them from being crushed by vehicles.

[0032] Preferably, the base 2 is connected to the protective tube 1 through a connector, and the connector includes a mating protrusion and a recessed portion to achieve radial positioning of the base 2 and the protective tube 1. It should be noted that the protrusion can be provided on the base and the recessed portion can be provided on the protective tube, or the protrusion can be provided on the protective tube and the recessed portion can be provided on the base, or both the base and the protective tube can be provided with mating protrusions and recessed portions. In this embodiment, as shown in FIG. Figure 3 As shown, the left side of the protection tube 1 is provided with a recessed portion, the right side is provided with a raised portion, and the base 2 is provided with matching raised portions and recessed portions, which are not specifically limited here.

[0033] Preferably, the recessed portion has a circular inner surface, and the raised portion has a circular outer surface, so that the raised portion is in close contact with the recessed portion.

[0034] Preferably, Figure 3 As shown, the protection tube 1 is provided with a first recessed portion 41 , and the base 2 is provided with a second raised portion 42 . The second raised portion 42 can be inserted into the first recessed portion 41 and drive the protection tube 1 to move along the length direction of the first recessed portion 41 .

[0035] Preferably, the first recessed portion 41 is provided on a side of the protective tube 1 close to the cable.

[0036] Preferably, the opening of the first recessed portion 41 faces the protection cavity. In this embodiment, the first recessed portion 41 with its opening facing the right is provided on the left side of the protection tube 1 near the bottom. The first recessed portion 41 is provided along the length direction of the protection tube 1.

[0037] Preferably, Figure 2 and Figure 3 As shown, the protection tube 1 is provided with a first protrusion 43, and the base 2 is provided with a second recess 44. The first protrusion 43 can be inserted into the second recess 44 and drive the protection tube 1 to move along the length direction of the second recess 44. In this embodiment, as shown in FIG. Figure 2 As shown, a second protrusion 42 is provided on the left side of the base 2, and a first recessed portion 41 matching the second protrusion 42 is provided on the corresponding protective tube 1, and the opening of the first recessed portion 41 faces the right side. A second recessed portion 44 is provided on the upper right side of the base 2, and a first protrusion 43 matching the second recessed portion 44 is provided on the corresponding protective tube. The two groups of protrusions and recessed portions cooperate with each other to prevent radial movement of the protective tube 1, and further prevent radial movement between the protective tube 1 and the base 2, thereby playing a better protective role.

[0038] Preferably, Figure 4 As shown, adjacent end surfaces of the protective tubes 1 close to each other are respectively provided with a third protrusion 11 and a third recess 12 for accommodating the third protrusion 11 , so as to achieve axial limitation of the protective tubes 1 .

[0039] Preferably, the cross section of the protection tube 1 is arc-shaped. The curvature of the protection tube 1 is not specifically limited as long as it ensures smooth passage of vehicles and prevents damage to the cables in the protection cavity.

[0040] Preferably, the protection tube 1 is provided with an extension plate 5 to increase the contact area between the device and the ground. Figure 1 As shown, an extension plate 5 having the same height as the base 2 is provided on the left side of the protective tube 1, which plays a better transition role. From the outside, both sides of the protective tube 1 have structures extending outward, which not only increases the contact area between the device and the ground, but also makes passing vehicles smoother, reduces the pressure and impact on the device, and plays a better protective role.

[0041] Preferably, the protection tube 1 and the extension plate 5 are integrally formed.

[0042] Preferably, the end surface of the base 2 near the second recessed portion 44 extends far away. In this embodiment, the right side of the base 2 extends far away, that is, extends to the right side of the second recessed portion 44, so that there is a transition on both sides of the device during use, which not only increases the contact area between the device and the ground, but also makes passing vehicles smoother, reduces pressure and impact on the device, and provides better protection.

[0043] Preferably, a plurality of support members 3 are symmetrically distributed on both sides of the cable to disperse the pressure.

[0044] Preferably, the end portion of the support member 3 connected to the protection tube 1 is in an arc shape that fits the inner circle of the protection tube 1 .

[0045] Preferably, the support members 3 are multiple reinforcement members that simultaneously connect the protective tube 1 and the base 2. In this embodiment, the support members 3 are W-shaped and supported between the protective tube 1 and the base 2. The top of the support members 3 is connected to the curved surface of the protective tube 1, and the bottom is fixed to the base 2. This not only provides good reinforcement, but also reasonably distributes the pressure of the vehicle to prevent damage to the device and better protect the cable.

[0046] Preferably, a stopper 6 is provided on the second protrusion 42 and / or the second recess 44 to limit the lateral movement of the protection tube 1. In this embodiment, taking the second protrusion 42 as an example, a pin hole is provided on its upper end surface, and a pin shaft, i.e., the stopper 6, is inserted into the hole. The pin shaft will limit the axial displacement of the protection tube 1. Figure 5 As shown, the stopper is provided so that the end face of the base 2 on the same side is offset from the end face of the protective tube 1 by a certain distance, thereby securing the two adjacent protective tubes 1 together using the base 2 to prevent misalignment of the two adjacent protective tubes 1. Of course, the stopper can also be a blocking piece or block movably connected to the second protrusion 42 or the second recessed portion 44. This is not specifically limited here, as long as it can achieve the same function.

[0047] Preferably, the bottom of the base plate 2 is connected to the ground. In this embodiment, the extension plate 5 and the base 2 are designed in two layers. The lower layer that contacts the road surface is made of elastic material such as rubber. The upper and lower layers are effectively connected by riveting or other means to enhance the anti-slip ability. When in use, the base 2 can be fixed to the ground.

[0048] When in use, fix the base 2 on the ground, insert the protective tube 1 into the top of the base 2 along the angle at which the protrusions and the recesses cooperate with each other, and pass the cable from under the support 3. If the road is too wide, use multiple bases 2 and protective tubes 1 together. When connecting two adjacent protective tubes 1, use them together, insert the third protrusion 11 into the third recess 12 of the adjacent protective tube 1, and then insert the base 2 into the protective tube 1 along the angle at which the protrusions and the recesses cooperate with each other, but ensure that there is a certain distance between the end face of the base 2 and the end face of the protective tube 1, and insert the pin to prevent the two adjacent protective tubes 1 from being misaligned. Pass the cable from under the support 3, which is easy to assemble and disassemble. All components are made of metal.

[0049] The beneficial effects of the present invention are as follows: an arc-shaped protective tube and a support member supporting the arc-shaped protective tube and the base are provided, and the cable is placed in the protective cavity, which can not only effectively protect the cable from damage, but also reasonably disperse the pressure of passing vehicles so that the protective device will not be flattened or even crushed, causing waste of resources; the mutually cooperating recessed portions and raised portions between adjacent protective tubes can prevent the axial movement of the protective tubes; the mutually cooperating recessed portions and raised portions between the protective tubes and the base can prevent the radial movement of the protective tubes, and further prevent the radial movement between the protective tubes and the base; when multiple protective tubes and bases are used in combination, they are connected into a solid whole, which can also act as a speed bump.
