[0031] In related technologies, existing buried cables may be compressed and damaged when soil subsidence or cable thermal expansion and contraction occur.

[0032] In view of this, such as Figures 1-4 As shown, some embodiments of this utility model provide a buried cable protection device, including a telescopic component and a protection component; the protection component is sleeved on the cable 202, and both ends of the protection component are tightly connected to the surface of the cable 202; the protection component is provided with a telescopic component; multiple telescopic components are provided, and the multiple telescopic components divide the protection component into several segments; each telescopic component is connected to a segment of the protection component on both sides; and each telescopic component can be stretched or compressed in the length direction.

[0033] In the above embodiments, the protective component can be made of metal and can be cylindrical. The protective component is sleeved on the surface of the cable 202. The telescopic component can be made of rubber and metal and can be folded tube or cylindrical. The telescopic component is connected to the protective component. When the protective component is divided into multiple segments, a telescopic component is connected between adjacent protective components at both ends. The telescopic component effectively responds to the deformation caused by soil settlement and thermal expansion and contraction of the cable. The protective component effectively avoids drastic temperature changes in the cable and prevents damage to the cable 202.

[0034] This utility model provides a buried cable protection device, including a telescopic component and a protective component. The protective component is sleeved on the cable 202, and both ends of the protective component are tightly connected to the surface of the cable 202. The protective component is provided with a telescopic component. Multiple telescopic components are provided, and the multiple telescopic components divide the protective component into several segments. Each telescopic component is connected to a protective component on both sides. Each telescopic component can be stretched or compressed in the length direction. The telescopic components solve the problem of the cable 202 being squeezed when the soil settles or the cable expands and contracts due to thermal expansion and contraction. The protective components protect the cable 202, solving the technical problem of cable damage under pressure in the prior art and achieving the technical effect that the cable 202 is not easily damaged.

[0035] In an optional embodiment, the telescopic assembly includes a telescopic tube 102, a fixing plate 103, a connecting plate 105, and a limiting block 106. Both ends of the telescopic tube 102 are connected to the flange of the protective assembly. A fixing plate 103 is provided at each end of the telescopic tube 102. The two fixing plates 103 are arranged opposite to each other. Each fixing plate 103 is provided with a limiting groove. The two limiting grooves are arranged opposite to each other. The connecting plate 105 extends into the two limiting grooves and slides. A limiting block 106 is connected at each end of the connecting plate 105. Each limiting block 106 is slidably connected to a limiting groove. The limiting block 106 can abut against the opening of the limiting groove.

[0036] In the above embodiment, the telescopic tube 102 can be made of rubber. Both ends of the telescopic tube 102 can be provided with a flange. The telescopic tube 102 is connected to the protective component through the flange. Each flange of the telescopic tube 102 is fixed with a connecting plate 105. The connecting plate 105 is rectangular. The ends of the two connecting plates 105 that are close to each other are provided with a limiting groove. The limiting groove is elongated. The two sides of the connecting plate 105 extend into the limiting groove and slide, thereby preventing the telescopic tube 102 from twisting. Each end of the connecting plate 105 is connected with a limiting block 106. The thickness of the limiting block 106 is greater than the thickness of the connecting plate 105. A step is provided at the opening of the limiting groove. The limiting block 106 abuts against the opening of the limiting groove, thereby preventing the limiting block 106 from sliding out of the limiting groove, limiting the maximum elongation of the telescopic tube 102, and preventing the telescopic tube 102 from over-elongating and breaking.

[0037] In an optional embodiment, the telescopic assembly further includes two springs 104, one of which is provided in each limiting groove. One end of the spring 104 abuts against the limiting block 106, and the other end of the spring 104 abuts against the limiting groove.

[0038] In the above embodiment, the spring 104 can be configured as a columnar spring 104. Each limiting groove is provided with a spring 104. One end of the spring 104 abuts against the limiting block 106, and the other end abuts against the inner wall of the limiting groove. When the telescopic tube 102 is compressed, the two fixing plates 103 on both sides move closer to each other, thereby causing the connecting plate 105 to squeeze the springs 104 on both sides, making the compression process of the telescopic tube 102 more gentle, while counteracting the external pressure.

[0039] In an optional embodiment, the telescopic assembly further includes a damper 3. Two dampers 3 are provided, one in each spring 104. The damper 3 is fixed in the limiting groove and is used to limit the stroke of the spring 104.

[0040] In the above embodiment, the damper 3 can be cylindrical. The damper 3 is fixed at the axis of the spring 104 and is located inside the spring 104. The shortest stroke of the damper 3 is greater than the shortest stroke of the irreversible change of the spring 104, thereby preventing the spring 104 from being unable to recover its deformation after being compressed.

[0041] In an optional embodiment, the protection component includes a protective sleeve 101 and a protective net 201; the protective sleeve 101 is sleeved on the cable 202, and a protective net 201 is provided at both ends of the protective sleeve 101. The protective net 201 is sleeved on the cable 202 and is connected to the protective sleeve 101 and the cable 202 respectively.

[0042] In the above embodiments, the protective sleeve 101 can be made of metal, and the protective sleeve 101 can be cylindrical. Multiple protective sleeves 101 can be provided, and multiple protective sleeves 101 are sleeved along the outer surface of the cable 202. A telescopic tube 102 is connected between adjacent protective sleeves 101. A protective net 201 is connected to the end face of the first protective sleeve 101 and the last protective sleeve 101, respectively. The protective net 201 is circular, and the inner diameter of the protective net 201 is tightly connected to the outer surface of the cable 202. The outer diameter of the protective net 201 is tightly connected to the inner wall of the protective sleeve 101. The protective net 201 can prevent foreign objects such as mud and sand from entering the protective sleeve 101.

[0043] In an optional embodiment, the protective component further includes a drainage hole 203; multiple drainage holes 203 are provided, all of which are provided on the protective sleeve 101, and the multiple drainage holes 203 are spaced apart along the length direction of the protective sleeve 101.

[0044] In the above embodiment, the drain hole 203 can be circular, and multiple drain holes 203 are arranged in a straight line at the lowest point of the protective sleeve 101. Each drain hole 203 can drain the water inside the protective sleeve 101, thereby preventing water from corroding the cable 202 for a long time.

[0045] In an optional embodiment, the protection component further includes a one-way valve 204; multiple one-way valves 204 are provided, with one one-way valve 204 provided in each drain hole 203, and each one-way valve 204 is used for one-way discharge of water in the protective sleeve 101.

[0046] In the above embodiment, the number of one-way valves 204 is the same as the number of drain holes 203. Each drain hole 203 is equipped with a one-way valve 204. Each one-way valve 204 in each drain hole 203 can discharge the water in the protective sleeve 101 in one direction, while preventing the water below from entering the protective sleeve 101 again through the drain hole 203.

[0047] In an optional embodiment, a limiting ring 6 is also included; two limiting rings 6 are provided, and the two limiting rings 6 are respectively provided on both sides of the protective sleeve 101 and on the inner wall of the protective sleeve 101, and each limiting ring 6 abuts against a protective net 201.

[0048] In the above embodiments, the limiting ring 6 can be integrally formed with the protective sleeve 101 or welded to the protective sleeve 101. The limiting ring 6 is circular, and the inner diameter of the limiting ring 6 is smaller than the inner diameter of the protective sleeve 101. The outer diameter of the limiting ring 6 is equal to the inner diameter of the protective sleeve 101, so that after the limiting ring 6 is connected to the protective sleeve 101, the limiting ring 6 is stepped. The limiting ring 6 can be used to abut against the protective net 201, thereby better fixing the protective net 201.

[0049] In an optional implementation, a detection unit is also included, which is disposed between the protection component and the cable 202 and is connected to the protection component.

[0050] In an optional implementation, a transmission line 4 and a monitor 5 are also included. The transmission line 4 passes through the protection component and is connected to the detection unit. The other end of the transmission line 4 is connected to the monitor 5. The detection unit is electrically connected to the monitor 5 through the transmission line 4.

[0051] In the above embodiments, the detection unit may include a thermometer, a hygrometer, a pressure sensor and a displacement sensor. The detection unit can be used to measure the temperature, humidity, pressure changes of the soil on the protective sleeve 101 and the deformation of the protective sleeve 101, thereby effectively detecting the state of the underground protective sleeve 101, and can transmit the data to the monitor 5 on the ground through the transmission line 4, through which the underground state can be effectively observed.
