Description

Technical Field

[0001] This utility model relates to the field of submarine cable laying technology, specifically to a submarine cable laying and burial equipment. Background Technology

[0002] Submarine cables serve as power transmission and communication trunk lines connecting cities, continents, islands, and even internationally. They are currently the most reliable, safe, and effective means of telecommunications transmission. However, due to the complex conditions and high pressure on the seabed, the entire submarine cable laying work is difficult and dangerous. Therefore, it cannot be completed in one go and needs to be divided into three stages: line survey and clearing, cable laying, and burial protection. Burial equipment is required when laying submarine cables.

[0003] A search revealed Chinese patent CN110829285B, which discloses a burial device for laying submarine cables, including an upper support structure. While this device has the advantage of reducing power consumption, it still has the following problems:

[0004] 1. Cable lowering cannot be carried out during the excavation process, and the cable cannot be continuously lowered into the ditch by its own weight, making it difficult to lower the cable while excavating.

[0005] 2. If the cable cannot be effectively guided, pulled, and limited during the journey, it may fail to fall into the ditch when crossing it, affecting the normal cable laying. Utility Model Content

[0035] Reference Figures 1-6 A submarine cable laying and burying device includes a traveling vehicle 100. The traveling vehicle 100 has a digging mechanism 200, a cable lowering mechanism 300, and a flushing mechanism 400 mounted on its surface. The digging mechanism 200 includes a frame 201, a rotating pipe 202 rotatably connected to the surface of the frame 201, a rotating cylinder 203 fixedly sleeved on the surface of the rotating pipe 202, and a blade 204 welded to the surface of the rotating cylinder 203. The cable lowering mechanism 300 includes a horizontal plate 301, with a component rotatably connected to its bottom. A vertical roller 302 and a horizontal plate 301 are rotatably connected to one end of a short rod 303. A rotating plate 304 is fixedly connected to the lower end of the short rod 303. A movable roller 305 is rotatably connected to the bottom of the rotating plate 304. A baffle 306 is fixedly connected to the surface of the horizontal plate 301. The flushing mechanism 400 includes a water outlet pipe 401, one end of which is connected to the surface of a rotating pipe 202, and the other end is connected to the surface of a rotating drum 203. Punches 402 are rotatably connected to both ends of the rotating pipe 202 through sealed bearings.

[0036] Furthermore, the excavation mechanism 200 also includes a motor 205, which is fixedly connected to one side of the frame 201. The output shaft of the motor 205 is fixedly connected to a bevel gear 206, and a bevel gear 207 is fixedly sleeved on one end of the rotary tube 202. The bevel gear 206 meshes with the bevel gear 207.

[0037] Specifically, the motor 205 drives the first bevel gear 206 to rotate, which in turn drives the second bevel gear 207 to rotate, causing the rotating pipe 202, rotating drum 203 and blade 204 to rotate, thus performing the digging operation and excavating a trench into which the cable is subsequently buried. With the bevel gears 206 and 207 in place, when the motor 205 drives the rotating pipe 202 to rotate, it does not affect the water being discharged from the punch 402 through the rotating pipe 202.

[0038] Furthermore, a hydraulic rod 208 is fixedly connected to the surface of the traveling vehicle 100. The lower end of the hydraulic rod 208 is fixedly connected to the top of the frame 201. A cover 209 is fitted onto the surface of the motor 205. The cover 209 is fixedly connected to one side of the frame 201. A punch 402 penetrates the cover 209 and is fixedly connected to it.

[0039] Specifically, the height of the frame 201 is adjusted by hydraulic rod 208, which in turn adjusts the position of the drum 203 and the blade 204 to complete the excavation of the ditch from shallow to deep. The excavation depth is adjusted according to the actual situation. The cover 209 protects the motor 205, bevel gear 206 and bevel gear 207 from collisions and entanglement with debris, so that they can operate normally and stably.

[0040] Furthermore, the cable lowering mechanism 300 also includes a gear 307, which is fixedly connected to the upper end of the short rod 303. A hydraulic rod 308 is fixedly connected to the top of the horizontal plate 301, and a toothed plate 309 is fixedly connected to one end of the hydraulic rod 308. The gear 307 meshes with the toothed plate 309.

[0041] Specifically, by setting multiple vertical rollers 302, the side cable can be limited during the excavation process to prevent damage to the cable caused by the rotating drum 203 and blades 204. By controlling the retraction of the hydraulic rod 308, the toothed plate 309 is moved, which in turn drives the gear 307, short rod 303, horizontal plate 301 and movable roller 305 to rotate, swinging one end of the cable towards the excavated ditch. Under the combined guiding and limiting traction of the vertical rollers 302 and movable roller 305, and as the traveling vehicle 100 continues to advance and excavate, the cable continuously falls into the ditch under its own weight, realizing the simultaneous excavation and cable laying, and automatic burial by the flow of sea mud.

[0042] Furthermore, a T-shaped block 310 is fixedly connected to the bottom of the toothed plate 309, and a T-shaped groove 311 is opened on the top of the horizontal plate 301. The T-shaped block 310 is slidably connected in the T-shaped groove 311. A cover 312 is fitted on the surface of the hydraulic rod 308, the toothed plate 309 and the gear 307. The cover 312 is fixedly connected to the top of the horizontal plate 301.

[0043] Specifically, the T-slot 311 and T-block 310 guide and limit the toothed plate 309, allowing it to move only in its direction. At the same time, they support the toothed plate 309, reducing the force on the hydraulic rod 308 and protecting it. The cover 312 protects the toothed plate 309, gear 307, and hydraulic rod 308 from damage caused by collisions and entanglement.

[0044] Furthermore, a fixing rod 313 is fixedly connected to the surface of the traveling vehicle 100, the lower end of the fixing rod 313 is fixedly connected to the top of the cross plate 301, and a roller 314 is rotatably connected to one side of the baffle 306.

[0045] Specifically, the traveling vehicle 100 and the cross plate 301 are indirectly fixed by the fixing rod 313, so that the traveling vehicle 100 can drive the cable lowering mechanism 300 to move when it moves. The baffle 306 limits the cable pulled by the movable roller 305, so that it falls accurately into the ditch and does not cross the ditch. There are several rollers 314 to support the baffle 306, reduce resistance when moving, and indirectly support the cross plate 301, making the cable lowering mechanism 300 more stable.

[0046] Furthermore, the flushing mechanism 400 also includes a connecting pipe 403, one end of which is connected to the surface of a punch 402, and the connecting pipe 403 is fixedly connected to one side of the frame 201 via a support plate.

[0047] Specifically, water is delivered to a punch 402 through a connecting pipe 403, and then through a rotating pipe 202 so that it can exit from both punches 402, thereby flushing away the marine mud generated during the excavation process and improving the excavation effect and speed.

[0048] Furthermore, a water pump 404 is installed on the surface of the traveling vehicle 100. The output end of the water pump 404 is connected to a bend 405. One end of the bend 405 is sleeved on the surface of the connecting pipe 403. The input end of the water pump 404 is connected to a filter 406.

[0049] Specifically, the bend 405 is fitted onto the surface of the connecting pipe 403. The movement of the frame 201 drives the connecting pipe 403 to move, so that the bend 405 and the connecting pipe 403 can still maintain communication. The water entering the water pump 404 is filtered by the filter 406 to prevent impurities from entering and damaging the impeller in the water pump 404.

[0050] The working principle of this utility model:

[0051] S1. The operation of the control motor 205 causes the bevel gear 1 206 and bevel gear 207 to rotate, which in turn causes the rotating pipe 202, connecting pipe 403, rotating drum 203 and blade 204 to rotate. The extension of the control hydraulic rod 1 208 drives the frame 201, rotating drum 203 and blade 204 to move downward. Under the action of the rotating drum 203 and blade 204 rotating and moving downward, digging is performed.

[0052] S2. Control the forward movement of the traveling vehicle 100, the operation of the water pump 404, and the retraction of the hydraulic rod 308. The movement of the traveling vehicle 100 drives the excavation mechanism 200 to move, and excavates according to the orientation of the cable. The operation of the water pump 404 filters the water through the filter 406, and then discharges it from one end of the punch 402 and the connecting pipe 403 through the bend 405, the connecting pipe 403, and the turn pipe 202, thereby flushing the sea mud during the excavation process, improving the excavation efficiency, and allowing the cable to fall into the ditch better.

[0053] S3, the retraction of hydraulic rod 308 causes the toothed plate 309 to move, which in turn drives the gear 307, short rod 303, horizontal plate 301 and movable roller 305 to rotate, swinging one end of the cable toward the excavated ditch. Under the guidance and limiting traction of vertical roller 302 and movable roller 305, and as the traveling vehicle 100 continues to advance and excavate, the cable continuously falls into the ditch under its own weight. The baffle 306 limits the cable pulled by the movable roller 305, making it fall into the ditch more accurately and preventing it from crossing the ditch and failing to fall into it. This achieves cable lowering while traveling and excavating, and automatic burial under the flow of sea mud.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
