Description
Technical Field
[0001] The present application relates to the technical field of cable trenches, and in particular to a recessed cable burial channel. Background Art
[0002] Direct buried cable laying relies on facilities such as the ground, wall, underground, underwater, tunnel, wall hole, etc. First, a channel for placing the cable is built, and a bracket is installed, and then the cable is laid. It has the advantages of small investment, convenient construction and good heat dissipation conditions. It is the most economical and widely used laying method.
[0003] However, the current direct buried cable laying excavation method is regular, and there is no reserved placement space for cable laying. It must rely on the corresponding cable wells for loss reservation. However, the cable wells are usually large in size and cannot be used in restricted areas, and large-scale excavation is not possible. Due to the limited excavation of the laying section, it is impossible to do channel reservation inspection and cable facilities. When the power supply line fails, secondary excavation is required for overall replacement, which causes a certain degree of interference to the surrounding environment and residents. At the same time, the cost of replacement is also extremely high. In order to reduce repetitive work and improve construction efficiency. Utility Model Content

DETAILED DESCRIPTION
[0034] The following is combined with Figure 1-4 This application is described in further detail.
[0035] The present application embodiment discloses a recessed cable burial channel. Figure 1A recessed cable burying channel includes a cable trench 1, a cable 2 is laid in the cable trench 1, and a sunken cable trough 3 is opened along the width direction of the cable trench 1 in the section where the cable trench 1 cannot be provided with a cable 2 well. In the present application, the number of sunken cable troughs 3 opened in the section where the cable trench 1 cannot be provided with a cable 2 well is 2-3. The excavation depth of the sunken cable trough 3 is deeper than that of the cable trench 1, and the cable 2 passes through the sunken cable trough 3, thereby satisfying the laying margin of the cable 2. In order to avoid secondary excavation when the cable 2 fails, a box structure 4 is fixedly placed in the sunken cable trough 3, and a group of guide wheels 5 are arranged on the upper surface of the box structure 4. The guide wheels 5 are placed in the sunken cable trough 3, that is, the height of the guide wheels 5 does not exceed the sunken cable trough 3. The cable 2 passes through the sunken cable trough 3 and passes through the middle of the group of guide wheels 5. The guide wheels 5 clamp the cable 2 and can convey the cable 2 by rotating. In the present application, the guide wheels 5 are elastic, so they will not cause wear to the cable 2.
[0036] A driving structure 6 is arranged in the box structure 4 , which can drive a group of guide wheels 5 to rotate simultaneously, thereby realizing electric transmission of the cable 2 .
[0037] A transmission shaft 7 is passed through the cable trench 1 along the length direction of the cable trench 1. The transmission shaft 7 is on the same horizontal line as the bottom of the sunken cable trench 3. One end of the transmission shaft 7 is fixedly connected to the driving structure 6, and the other end is located at one side of the sunken cable trench 3 and fixedly connected to a variable pressure motor 8 placed in the cable trench 1. The variable pressure motor 8 drives the transmission shaft 7 to rotate. A cable entry device 9 is arranged on one side of the sunken cable trench 3 in the cable trench 1.
[0038] Since the transmission shaft 7 between two adjacent sunken cable troughs 3 is directly buried underground, in order not to affect the free rotation of the transmission shaft 7, a protective sleeve 10 is provided on the transmission shaft 7 between two adjacent sunken cable troughs 3. The protective sleeve 10 can also prevent the transmission shaft 7 from being worn or corroded.
[0039] Reference Figure 2 and Figure 3 A partition 41 is arranged inside the box structure 4, and the partition 41 divides the inside of the box structure 4 into a lower cavity 42 and an upper cavity 43; the width of the box structure 4 gradually increases from the bottom to the top, so that the burial of the box structure 4 in the sunken cable trough 3 is more stable.
[0040] The driving structure 6 includes a bevel gear assembly 61, a gear assembly 62 and a set of fixed shafts 63. The bevel gear assembly 61 is arranged in the lower cavity 42. The transmission shaft 7 passes through both sides of the lower cavity 42 and rotates relative to the lower cavity 42. The transmission shaft 7 is fixedly connected to the bevel gear assembly 61. The gear assembly 62 is horizontally arranged in the upper cavity 43. A set of fixed shafts 63 is vertically arranged in the box structure 4 and passes through the partition 41. The fixed shaft 63 rotates relative to the partition 41. The gear assembly 62 in the upper cavity 43 is sleeved on the fixed shaft 63 and is fixedly connected to the fixed shaft 63; the bevel gear assembly 61 in the lower cavity 42 is fixedly connected to the end of the fixed shaft 63. The transmission shaft 7 drives the bevel gear assembly 61 to rotate through its own transmission, the bevel gear assembly 61 drives the gear assembly 62 to rotate, and the gear assembly 62 drives a set of guide wheels 5 to rotate in the same direction, so as to achieve the purpose of the guide wheels 5 conveying the cable 2.
[0041] The fixed shaft 63 includes a first fixed shaft 631 and a second fixed shaft 632. The first fixed shaft 631 passes through the top of the box structure 4 and is fixedly connected to a guide wheel 5. The second fixed shaft 632 passes through the top of the box structure 4 and is fixedly connected to another guide wheel 5. There is a gap between the two guide wheels 5 for the cable 2 to pass through.
[0042] Reference Figure 3 The bevel gear assembly 61 includes a first bevel gear 611 and a second bevel gear 612. The first bevel gear 611 is sleeved on the transmission shaft 7 and fixedly connected to the transmission shaft 7. The second bevel gear 612 is perpendicular to and meshes with the first bevel gear 611. The second bevel gear 612 is arranged below the partition 41 and fixedly connected to the end of the first fixed shaft 631.
[0043] Reference Figure 2 and Figure 3 The gear assembly 62 includes a first gear 621 and a second gear 622, which are meshed and horizontally arranged on the partition 41. The first gear 621 is sleeved on the first fixed shaft 631 and fixedly connected to the first fixed shaft 631, and the second gear 622 is sleeved on the second fixed shaft 632 and fixedly connected to the second fixed shaft 632. When the first bevel gear 611 drives the second bevel gear 612 to rotate, the first fixed shaft 631 rotates immediately, thereby driving the first gear 621 to rotate. Since the first gear 621 and the second gear 622 are meshed, the second gear 622 also rotates simultaneously with the first gear 621, thereby realizing a group of guide wheels 5 rotating in the same direction.
[0044] Reference Figure 4Two fixing holes 411 are provided on the partition 41, and a circle of annular grooves 411-1 are provided on the circumferential sides of the two fixing holes 411 along the circumferential direction of the fixing holes 411. Annular blocks 631-1 are correspondingly provided on the first fixed shaft 631 and the second fixed shaft 632 along the circumferential direction of the first fixed shaft 631 and the second fixed shaft 632, and the annular blocks 631-1 are placed in the annular grooves 411-1, so as to realize the connection between the first fixed shaft 631 and the second fixed shaft 632 and the partition 41.
[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
