Description

Technical Field

[0001] This utility model relates to a hydraulic cable device, and more particularly to its buffer structure, belonging to the technical field of hydraulic devices. Background Technology

[0002] Rivers often carry floating debris such as timber, which drifts downstream. Retrieving this debris is crucial to prevent it from impacting and damaging downstream water conservancy facilities. However, the unstable nature of the floating debris limits the amount of timber that can be retrieved by existing salvage vessels, resulting in high energy consumption. Salvage efficiency is lowest, especially in fast-flowing rivers. Therefore, how to gather, collect, and salvage timber and other debris from rivers to prevent them from impacting and damaging downstream water conservancy facilities is a pressing technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0003] To overcome the aforementioned shortcomings, the purpose of this utility model is to provide a hydraulic cable device to solve one of the problems mentioned in the background section.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a hydraulic cable device, comprising a first fixed stake, a rope, and a second fixed stake, one end of the rope being connected to the first fixed stake and inclinedly set on the bank of a river; the hydraulic cable device also includes a tensioner and a spring, and the rope, tensioner, spring, and second fixed stake are connected in sequence.

[0005] A further feature of this invention is that the hydraulic cable device also includes a fixed pulley, and the rope is connected to the tensioner by passing around the fixed pulley.

[0006] The present invention is further configured such that: the first fixed stake, the rope, and the second fixed stake are multiple sets, which are arranged sequentially on the surface of the river with their upper and lower parts facing each other.

[0007] The present invention is further configured such that: the hydraulic cable device also includes a railing, the railing is provided with several through holes, and the multiple sets of ropes pass through the several through holes respectively.

[0008] The present invention is further configured such that: a plurality of bearings are sleeved on the railing, and an outer ring is sleeved on the bearing; the outer ring is made of rubber.

[0009] A further feature of this invention is that the diameter of the outer ring at the middle position of the railing is larger than the diameter of the outer ring at other positions.

[0010] The present invention is further configured such that: the tensioner includes a rectangular frame, a pair of screws and a pair of hooks; the two ends of the rectangular frame are provided with threaded holes, the pair of threaded holes are respectively screwed to the pair of screws, and the pair of hooks are respectively fixedly connected to the outer ends of the pair of screws; the threads on the pair of screws are in opposite directions.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: Debris such as wood moves downstream with the water flow. By setting the rope at an angle along the riverbank, the debris is propelled along the rope by its force until it reaches the shallow water area where the rope meets the bank, where it is gathered and collected. Because the water is shallow near the bank, it is easier to retrieve the debris, improving retrieval efficiency. A tensioner and spring are used, with the rope, tensioner, spring, and second fixed stake connected in sequence. When debris impacts the rope, the spring extends, and the rope bends and expands. Once the impact force dissipates, the spring contracts, and the rope returns to its normal state, preventing the rope from breaking due to the debris. The tensioner is used to adjust the rope tension, causing the debris to move along the rope until it stops in the shallow water area near the bank.

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0019] See appendix Figure 1-4As shown, a hydraulic cable device in this embodiment includes a first fixed stake 3, a rope 2, and a second fixed stake 8. One end of the rope 2 is connected to the first fixed stake 3 and is inclinedly set on the bank 1 of the river. The hydraulic cable device also includes a tensioner 6 and a spring 7. The rope 2, tensioner 6, spring 7, and second fixed stake 8 are connected in sequence.

[0020] Debris such as wood moves downstream with the water flow. By setting rope 2 at an angle on the riverbank 1, the debris is propelled along rope 2 by its force until it reaches the shallow water area where rope 2 forms an angle with the bank 1, where it is gathered and collected. Because the water is shallow in the area near the bank 1, it is easier to retrieve the debris, improving retrieval efficiency. A tensioner 6 and a spring 7 are used, with rope 2, tensioner 6, spring 7, and a second fixed stake 8 connected in sequence. When debris impacts rope 2, spring 7 extends, causing rope 2 to bend and expand. Once the impact force dissipates, spring 7 contracts, and rope 2 returns to its normal state, preventing it from breaking due to the debris. Tensioner 6 is used to adjust the tension of rope 2, causing debris to move along rope 2 until it stops in the shallow water area near the bank 1.

[0021] A further feature of this invention is that the hydraulic cable device includes a fixed pulley 5, and the rope 2 is connected to the tensioner 6 by passing around the fixed pulley 5. By changing the direction of the rope 2 through the fixed pulley 5, the end of the rope 2 is brought from the water surface to above the water surface, avoiding the need to install the tensioner 6, spring 7, and second fixed stake 8 underwater. This facilitates implementation and operation.

[0022] To prevent debris such as timber from overflowing the rope 2 and flowing downstream, this invention is further configured such that the first fixing stake 3, the rope 2, and the second fixing stake 8 are multiple sets, arranged sequentially and vertically on the river surface. The multiple sets of ropes 2 form a three-dimensional interception structure on the water surface, effectively preventing debris such as timber from passing over or under the rope 2.

[0023] To prevent debris such as wood from passing through the gaps between adjacent ropes 2, the present invention is further configured such that: the hydraulic cable device also includes a railing 4, the railing 4 is provided with a plurality of through holes 11, and the plurality of ropes 2 pass through the plurality of through holes 11 respectively.

[0024] To reduce friction between debris such as wood and the railing 4 and to facilitate the movement of the debris along the rope 2, this invention further includes: several bearings 10 are fitted onto the railing 4, and an outer ring 9 is fitted onto each bearing 10; the outer ring 9 is made of engineering plastic. When the debris such as wood moving with the water flow comes into contact with the outer ring 9, the outer ring 9 rotates around the railing 4. This transforms the friction between the debris and the railing 4 into rolling, reducing the frictional force on the railing 4.

[0025] The present invention is further configured such that the diameter of the outer ring 9 at the middle position of the railing 4 is larger than the diameter of the outer ring 9 at other positions.

[0026] The present invention is further configured such that: the tensioner 6 includes a rectangular frame 61, a pair of screws 64, and a pair of hooks 62; the two ends of the rectangular frame 61 are provided with threaded holes 63, the pair of threaded holes 63 are respectively screwed to the pair of screws 64, and the pair of hooks 62 are respectively fixedly connected to the outer ends of the pair of screws 64; the threads on the pair of screws 64 are in opposite directions. The pair of hooks 62 are respectively connected to the rope 2 and the spring 7. By rotating the rectangular frame 61 in the forward direction, the pair of screws 64 move relative to each other in the threaded holes 63, moving away from each other, increasing the overall length of the tensioner 6, and slackening the rope 2. By rotating the rectangular frame 61 in the reverse direction, the pair of screws 64 move towards each other in the threaded holes 63, moving closer to each other, decreasing the overall length of the tensioner 6, and tightening the rope 2.
