For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific situations.

[0065] Please refer to Figures 1 to 2 , a direct-buried cable excavation device provided in the embodiments of the present application includes: a support frame 10, a swing assembly 20, a spraying assembly 30, a pumping assembly 40, and an excavation assembly;

[0066] The support frame 10 is internally provided with an excavation cavity 11 that penetrates vertically. Among them, the support frame 10 can be in the shape of a square frame.

[0067] The swing assembly 20 includes: two swing plates 21; the swing plates 21 are rotatably connected to the support frame 10, and the two swing plates 21 are respectively arranged on two opposite side walls inside the excavation cavity 11. Among them, the rotation directions of the two swing plates 21 are in the vertical plane, that is, the rotation axes of the swing plates 21 are horizontally arranged.

[0068] Please refer to Figures 1 to 4 , the spraying assembly 30 includes: a water tank 31, a water pump 32 and a water outlet pipe 33; the top of the support frame 10 is provided with a water inlet hole 12 for detachably connecting one end of the water outlet pipe 33, and the bottom is provided with a plurality of nozzles 13; among them, the plurality of nozzles 13 can be arranged in a straight line at uniform intervals. The other end of the water outlet pipe 33 is detachably connected to the water pump 32; the water pump 32 is detachably connected to the water tank 31.

[0069] Specifically, the spraying assembly 30 is used to spray liquid onto the ground. During use, after connecting the spraying assembly 30 to the support frame 10, open the valve of the water tank 31 and turn on the water pump 32, so that water flows into the water inlet hole 12 along the outlet pipe 33, and then is sprayed onto the ground below the support frame 10 through the nozzles 13, so that the soil and sand are injected with water and become mud.

[0070] The extraction assembly 40 includes: a storage tank 41, a booster pump 42 and an extraction pipe 43; the swing plate 21 is penetrated with an extraction hole 22 for detachably connecting one end of the extraction pipe 43; the other end of the extraction pipe 43 is detachably connected to the booster pump 42; the booster pump 42 is detachably connected to the storage tank 41.

[0071] Specifically, the extraction assembly 40 is used to extract the mud into the storage tank 41. Connect the extraction assembly 40 to the swing assembly 20, and after the spraying assembly 30 injects enough water into the ground, open the valve of the storage tank 41 and turn on the booster pump 42. During the swinging process of the swing plate 21, the mud is extracted into the storage tank 41 through the extraction hole 22 and the extraction pipe 43.

[0072] Among them, the support frame 10 can be a foldable structure. When not in use, the extraction assembly 40 and the spraying assembly 30 can be disassembled, and after folding the support frame 10 and the swing assembly 20, they can be stored on the vehicle body for convenient handling.

[0073] Please refer to Figure 5 And Figure 6 , the excavation assembly includes: a rotating excavator 51 and a rotating brush 52; the bottom of the swing plate 21 is provided with a first clamping member 23 for detachably connecting the rotating excavator 51 or the rotating brush 52.

[0074] Specifically, when the rotating excavator 51 is installed on the swing plate 21, it can rotate during the swinging of the swing plate 21 to excavate the ground. During the excavation process, the mud is gradually broken up and then pumped away by the extraction assembly 40. The support frame 10 gradually descends and approaches the cable as the mud is pumped away. When the distance between the support frame 10 and the cable is less than the first preset distance, such as 10 mm, the rotation of the swing plate 21 and the rotating excavator 51 is stopped, and the rotating excavator 51 is replaced with a relatively soft rotating brush 52 to avoid causing secondary damage to the cable.

[0075] In this specific embodiment, the solution may further include: a detection assembly (not shown in the figure); the detection assembly includes: a processor, a detection coil, a signal receiver, and a signal transmitter; a wire clamp is provided on the signal transmitter for connecting to the end of the cable through the wire clamp; the processor is electrically connected to the detection coil, the signal receiver, and the signal transmitter for judging the depth, direction, and fault location of the cable.

[0076] Specifically, the detection coil and the signal receiver can be integrated on a detection board. The detection board can be detachably connected to the swing plate 21. After the detection assembly, the support frame 10, the swing assembly 20, the spraying assembly 30, the extraction assembly 40, and the excavation assembly are self-tested normally, the signal transmitter is connected to the end of the faulty cable through the wire clamp. Through the cooperation of the detection coil, the signal receiver, and the signal transmitter, the electromagnetic field signal and the audio signal of the cable are detected and sent to the processor, so that the processor simulates and presents the image of the position, direction, depth, and fault location of the cable.

[0077] After that, the support frame 10 is moved to the fault location so that the fault location is in the exact middle of the support frame 10. And the swing assembly 20, the spraying assembly 30, and the extraction assembly 40 are installed on the support frame 10. The following steps are carried out:

[0078] S1. The processor judges the distance between the swing plate 21 and the cable in combination with the depth information obtained from the simulation result. If it is greater than the second preset distance (such as 1500 mm), then first manually mechanically excavate the soil until the distance between the swing plate 21 and the cable is less than the second preset distance, and then enter step S2;

[0079] S2. Remove the detection board and install the rotating excavator 51 at the bottom of the swing plate 21. And inject water liquid onto the ground through the spraying assembly 30. After the soil becomes mud, start the extraction assembly 40 to extract the mud, and at the same time, the swing plate 21 starts to swing and the rotating excavator 51 starts to rotate for excavation. The support frame 10 continuously descends and approaches the cable during the excavation. After judging that the distance between the swing plate 21 and the cable is less than the first preset distance (such as 10 mm), stop the operation and enter step S3;

[0080] S3. Remove the rotary excavator 51 and install the rotary brush 52 at the bottom of the swing plate 21. The rotary brush 52 rotates and gradually sweeps away the soil and sand through the bristles on it to expose the cable fault. Secondary damage to the cable can be avoided, and then the staff can carry out emergency repairs in the excavation cavity 11.

[0081] It should be noted that before excavation in step S1, when it is determined that the distance between the swing plate 21 and the cable is within a preset range (such as 700 to 1500 mm), the rotary excavator 51 can be not installed and the excavation can be directly carried out through the rotary brush 52. Among them, the liquid in the water tank 31 can be a high-pressure equipment cleaning agent composed of polymer materials. While it can be mixed with sand and soil, the part covering the cable can also form a semi-permanent protective film on the cable surface and the break, which has protective effects such as water repellency, mildew prevention, and improving the antioxidant property of the equipment.

[0082] In a more specific embodiment, please refer to Figure 5 , the rotary excavator 51 includes: a connecting plate 511 and a plurality of excavation shafts 512; a second clamping member for detachably connecting with the swing plate 21 is arranged on the connecting plate 511; the plurality of excavation shafts 512 are rotatably arranged at the bottom of the connecting plate 511, and a plurality of circumferentially distributed excavation teeth are fixed on the excavation shafts 512.

[0083] Among them, a clamping block can be arranged at the top of the connecting plate 511. A clamping groove can be arranged at the bottom of the swing plate 21, and the clamping connection between the connecting plate 511 and the swing plate 21 is realized through the cooperation of the clamping groove and the clamping block. In this embodiment, the first clamping member on the swing plate 21 is a tapered clamping strip arranged at its bottom. Correspondingly, the second clamping member is a tapered clamping groove.

[0084] Furthermore, the plurality of excavation shafts 512 are arranged in parallel at intervals; the plurality of excavation shafts 512 have two rotation directions.

[0085] Specifically, at the front and rear ends along the arrangement direction of the excavation shafts 512, the rotation directions of the front excavation shaft 512 and the rear excavation shaft 512 can be set to be opposite, so as to improve the rate of the excavation shafts 512 to disperse the slurry.

[0086] In other embodiments, please refer to Figure 6 , the rotary brush 52 includes: a support plate 521 and a plurality of brush shafts 522; a third clamping member for detachably connecting with the swing plate 21 is arranged on the support plate 521; the plurality of brush shafts 522 are rotatably arranged at the bottom of the support plate 521, and a plurality of circumferentially distributed bristles are fixed on the brush shafts 522.

[0087] Accordingly, in this embodiment, the first engaging member on the swing plate 21 can be a tapered clamping bar provided at its bottom. Correspondingly, the third engaging member is a tapered clamping groove. Moreover, the excavation shaft 512 can be made of steel, and the brush shaft 522 can be made of hard plastic.

[0088] Furthermore, a plurality of brush shafts 522 are arranged in parallel at intervals; the plurality of brush shafts 522 have two rotation directions.

[0089] Similarly, at the front and rear ends along the arrangement direction of the brush shafts 522, the rotation directions of the front brush shaft 522 and the rear brush shaft 522 can be set to be opposite, so as to improve the rate of cleaning mud and sand by the brush shafts 522.

[0090] Furthermore, through holes 53 communicating with the extraction holes are provided on the rotating excavator 51 and / or the rotating brush device 52, facilitating the entry of mud or mud and sand into the extraction holes 22 from the through holes 53 during their use.

[0091] In a further improved embodiment, please refer to Figure 7 , the swing plate 21 includes: a plate body 211 and a rotating shaft 212; the rotating shaft 212 is rotatably connected to the support frame 10; the plate body 211 is fixedly connected to the rotating shaft 212, and the swing angle of the plate body 211 is greater than 180°.

[0092] Specifically, the rotating shaft 212 is arranged outside the support frame 10. After the plate body 211 swings to be parallel to the support frame 10, it can further swing to expand the excavation range and improve the excavation efficiency.

[0093] In other embodiments, the swing assembly 20 further includes: two elevators 24; the two elevators 24 are respectively arranged on two opposite side walls in the excavation cavity 11 in a liftable manner; the swing plate 21 is rotatably connected to the elevators 24.

[0094] The elevators 24 can drive the swing plate 21 to lift and lower during the excavation process to adjust the excavation position. Specifically, during the process of the extraction assembly 40 sucking away the mud, the elevators 24 can drive the swing plate 21 to slowly descend, and at the same time, the support frame 10 slowly descends along with the excavation process.

[0095] In a more specific embodiment, please refer to Figure 1 , the support frame 10 includes: two fixing plates 101 and two hinge plates 102; the hinge plates 102 are of a foldable hinge structure; both ends of the hinge plates 102 are respectively rotatably connected to the two fixing plates 101; the two hinge plates 102 are arranged oppositely.

[0096] The support frame 10 with a foldable structure is formed by the two fixing plates 101 and the two hinge plates 102. Among them, the swing plate 21 can be arranged on the two fixing plates 101.

[0097] Further, it further includes two lifting plates 14; the two lifting plates 14 are rotatably arranged at the bottom of the hinge plate 102.

[0098] Specifically, during the excavation process, the two hinge plates 102 can be arranged on both sides of the axial direction of the cable. After excavating to the cable fault position, the swing of the swing plate 21 is stopped. The staff stands on the support frame 10, so that the support frame 10 descends under gravity, and the lifting plate 14 pierces into the soil under gravity, and the cable is jacked up and suspended as the support frame 10 descends, facilitating the maintenance by the staff.

[0099] Correspondingly, this solution can also be provided with a pedal (not shown in the figure). The pedal is detachably connected to the support frame 10 and is used for the staff to stand on.

[0100] In a more specific embodiment, please refer to Figure 1 and Figure 7 , a pointed extension 15 with a gradually decreasing cross-sectional area is arranged at the bottom of the fixing plate. It is convenient for the support frame 10 to descend during the excavation process.

[0101] Further, it further includes a plurality of extension frames; the extension frames have the same structure as the support frame 10 and are used for detachably connecting with the support frame 10 to extend the excavation cavity 11.

[0102] Specifically, as the excavation work progresses, after the support frame 10 is completely submerged in the ground, the extension frame can be installed on the support frame 10. The extension frame can be in the form of a square box with the same size as the support frame, so as to extend the excavation cavity 11 and prevent the surrounding soil and stones from falling into the excavation cavity 11.

[0103] Further, please refer to Figure 2 , both the water outlet pipe 33 and the extraction pipe 43 include a straight pipe and a Y-shaped pipe. Correspondingly, water inlet holes can be arranged at both ends of the support frame 10. The Y-shaped water outlet pipe 43 can be arranged to connect the water inlet holes at both ends of the support frame 10 at the same time. The Y-shaped extraction pipe 43 can be arranged to connect the extraction holes 22 on the two swing plates 21 at the same time. Among them, the Y-shaped pipe on the extraction pipe 43 can be arranged in the form of a telescopic rod, so as to expand and contract in cooperation with the swing of the swing plate 21. At the same time, the Y-shaped pipe on the water outlet pipe 33 can be arranged to have a smaller diameter than its straight pipe, so that the water pressure flowing into the Y-shaped pipe during the water outlet process increases, which is beneficial to high-pressure water outlet.

[0104] The above are the preferred embodiments of the present application and are not intended to limit the present invention.
