Description

Technical Field

[0001] This utility model relates to the field of optical cable laying technology, specifically a trenching and pre-burying device for DAS optical cables in soft geological conditions. Background Technology

[0002] Seismic exploration is a geophysical exploration method that uses the differences in elasticity and density of underground media to infer the properties and morphology of underground rock strata by observing and analyzing the propagation patterns of seismic waves generated by artificial earthquakes. Seismic exploration is the most important and effective method in geophysical exploration for solving oil and gas exploration problems. It is an important means of surveying oil and gas resources before drilling and is also widely used in coalfield and engineering geological exploration, regional geological research, and crustal research.

[0003] When conducting seismic exploration in desert areas, it is necessary to dig trenches to bury DAS optical cables. Traditional trenching tools include shovels and trenching machines. However, using shovels to dig pits is inefficient and requires a high level of physical strength from construction workers. On the other hand, using trenching machines will cause serious environmental damage.

[0004] Publication number CN216475273U discloses an automatic soil-carrying double-chain trencher, including a trenching device and a soil-carrying device. The trenching device is located at the rear end of a tractor, and the tractor drives the trenching device to move. The trenching device includes a rotatable trenching chain with cutters on it. The cutters can dig trenches on the ground by moving. The soil-carrying device is located above the trenching device and includes a soil-retaining mechanism and a conveying mechanism. The soil-retaining mechanism covers one side of the trenching chain and guides the soil loosened and lifted by the trenching chain to the conveying mechanism. The conveying mechanism transports the soil to other transport devices.

[0005] This existing technology causes significant environmental damage when used.

[0006] Announcement No. CN218479241U discloses an optical cable laying device, including a platform. Threaded holes are opened in the middle of both sides of the platform. Screws are rotatably connected inside the threaded holes on both sides. A first pulley is fixedly connected to the top of one screw, and a second pulley is fixedly connected to the top of the other screw. The first pulley and the second pulley are connected by a belt. A ground-breaking auger is fixedly connected to the drive end of the first motor.

[0007] The existing technology is difficult to control and has low laying efficiency.

[0008] Publication No.: CN118601078A discloses an integrated trenching and laying device for power construction, including a trenching component. The trenching component includes a base, and a moving component for driving the device to move is provided at the bottom of the base. A third fixed frame is installed on one side of the base. Two sets of the third fixed frames are provided. A first hydraulic lifting rod is provided on the top outer wall of the third fixed frame. The output end of the bottom of the first hydraulic lifting rod can slide through the third fixed frame. A second fixed frame is installed at the bottom end of the first hydraulic lifting rod. A second rotary motor is provided on one side outer wall of the second fixed frame. A second rotary shaft is connected to one side of the second rotary motor. One end of the second rotary shaft can rotatably pass through the second fixed frame. A digging frame is provided on the outer wall of the second rotary shaft. A reinforcement component for reinforcing the excavated trench and a burying component for burying cables are provided on one side of the base. The reinforcement component includes a second hydraulic lifting rod, which is fixed to the top outer wall of the base.

[0009] The existing hobbing cutter structure is easily damaged and difficult to replace, making it unsuitable for long-term use.

[0010] In summary, the technical solutions, technical problems to be solved, and beneficial effects of the above-disclosed technologies are all different from those of this utility model. For more technical features, technical problems to be solved, and beneficial effects of this utility model, the above-disclosed technical documents do not provide any technical inspiration.
