Description

Technical Field

[0001] The invention relates to the technical field of floating object interception in water conservancy projects, and in particular to a floating object interception device for a large reservoir and a use method thereof. Background Art

[0002] A river forms a reservoir through a dam, and a ship lock is set on one side of the dam for ships to pass through. In the reservoir, as the water from the upstream basin flows downward, it will carry a large amount of floating objects, such as plastic bottles and wood, which will accumulate on the upstream side of the dam. When the ship lock is in operation, these floating objects may enter the ship lock, causing the ship lock to get stuck or hindering the passage of ships. In a large reservoir, the amount of water discharged is about tens of thousands of cubic meters per second, and the water flow rate is high, which has a great impact on the barrier device.

[0003] Among the current floating object blocking devices, for example, Chinese patent document CN107986357A, published (announcement) date: 2018.05.04, discloses an assembled water pollution emergency interception and treatment device, including several interception units, which are connected end to end; the interception unit includes a float, a wire rope, a reinforcement belt, a material bag, a counterweight, and a protective frame, and the wire rope, the float, the reinforcement belt, the material bag, and the counterweight are installed on the protective frame from top to bottom in sequence, and the material bag for holding water pollution treatment materials is made of permeable mesh. Its characteristics are: convenient storage, simple installation, wide application, strong practicality, high emergency treatment efficiency, etc.; its disadvantage is that the device is used to intercept on the river channel, that is, the device is installed in a direction perpendicular to the river channel. If this installation method is adopted, first, the ship cannot pass, and second, the impact of floating objects on the device is large, and the structural strength of the device cannot be guaranteed.

[0004] In addition, in the Chinese patent document CN210315441U, the publication (announcement) date: 2020.04.14, a dam trash rack optimization device is disclosed, which is composed of a buoy cable, a trash buoy, and a trash steel twisted rope net. The trash steel twisted rope net is suspended in the middle of the buoy cable through a fixed steel buckle and a movable steel ring. One end of the buoy cable is fixed to the dam body, and the other end is fixed with a buoy. When the upstream water level rises, the trash steel twisted rope net will rise with the trash buoy and straighten the buoy cable, so that the trash steel twisted rope net is lifted, and the trash can be intercepted. When regularly cleaning the garbage around the trash rack, the steel lock buckle can be opened and the movable steel ring can be moved to make the rope net be retracted to form a gap, and then the boat can pass through the opened gap. Its characteristics are: it solves the problem of garbage floating in the upstream river channel flowing out from the gap between the trash rack and the dam, and also solves the traffic problem between the front and back of the trash rack when small boats clean garbage from the trash rack; its disadvantage is that when the device is installed on the upstream side of the dam body, the buoy of the device will move toward the dam body under the action of the water flow, resulting in the loss of the floating object interception function.

DETAILED DESCRIPTION

[0019] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0020] Embodiment 1: See also Figure 1-8 A floating object blocking device for a large reservoir includes a floating belt 10, a floating tube 20 and a mooring rope 30. The floating belt 10 and the floating tube 20 are respectively provided with a plurality of floating belts 10 and adjacent floating tubes 20 are connected in a string by the floating belt 10. The mooring rope 30 is installed at the bottom of the floating tube 20 and is used to connect and fix with the riverbed 40. The floating belt 10 and the floating tube 20 are respectively provided with a water-breaking structure.

[0021] By connecting the floating barrier belt 10 and the floating tube 20 in a string, the bottom of the floating tube 20 is connected and fixed to the riverbed 40 by the mooring rope 30, the blocking device is arranged along the river channel, and the water is broken by the water-breaking structure on the floating barrier belt 10 and the floating tube 20 to reduce the resistance to the water, so that the blocking device can ensure the interception effect even when the water flow rate is high.

[0022] In this embodiment, the mooring rope 30 is a steel wire rope.

[0023] In this embodiment, see Figure 2 , 34. The floating arresting belt 10 includes a float 11, on which at least one directional floating structure is arranged. The cross-section of the directional floating structure is streamlined, wide at the top and narrow at the bottom, and the two ends of the longitudinal section smoothly transition to the float 11, thereby forming the water-breaking structure. This structural design can optimize the distribution of buoyancy, ensure that the floating arresting belt 10 can maintain a proper floating state under different loading conditions, and at the same time reduce its weight by more than 50% compared with traditional floats. The smooth surface reduces the scratching and puncture of the floating arresting belt by branches and other floating objects when intercepting floating objects, avoiding surface damage. At the same time, this structural design can also reduce the resistance of the water flow, and at the same time produce a damping effect, which helps to reduce the swing amplitude of the float or floating body and reduce the impact of hydrodynamics on its stability. When the floating arresting belt 10 is tilted by the lateral force, the buoyancy point (i.e., the center of buoyancy) will generate a restoring torque relative to the center of gravity, which helps the floating arresting belt 10 effectively resist the tilt and restore balance to a vertical state. This structure has high mechanical strength and rigidity, which helps the floating belt 10 to maintain its shape when subjected to external forces. At the same time, the structure can better disperse the force of water waves or collisions, reduce direct impacts on the buoy, and improve its durability and safety.

[0024] Furthermore, a connecting rope 13 is installed penetrating through the floating barrier 10 , and at least two connecting ropes 13 are arranged at intervals in the upper and lower parts, and both ends of the connecting rope 13 are connected to the floating drum 20 respectively.

[0025] Further, the floating body 11 includes a first shell 111 and a second shell 112, the first shell 111 and the second shell 112 are fixedly connected, and limiting grooves 113 are respectively arranged on opposite sides of the first shell 111 and the second shell 112 and on both sides of the directional floating structure, and a plurality of fixed limiting rings 132 are arranged on the connecting cable 13, and the limiting rings 132 are located in the limiting grooves 113. Through the above structure, the floating body 11 is connected and fixed to the connecting cable 13, and because the limiting rings 132 are located in the limiting grooves 113, the floating body 11 will not slide on the connecting cable 13.

[0026] For easy connection, see Figure 6 , connecting rings 131 are also provided at both ends of the connecting rope 13.

[0027] In this embodiment, the connecting rope 13 is a steel wire rope.

[0028] See also Figure 3 The directional floating structure includes a bladder 12 , the upper side of the interior of the bladder 12 is filled with a floating material 121 , and the lower side of the interior of the bladder 12 is installed with a counterweight 122 .

[0029] In this embodiment, the floating material 121 is made of foamed foam, and the counterweight 122 is made of lead block.

[0030] The manufacturing process of the floating arresting belt 10 is as follows: First, pre-assembly is performed to place the connecting rope 13 and the lead block with horizontal bearing capacity into the first shell 111 or the second shell 112 of the semi-finished floating arresting belt 10 respectively.

[0031] Subsequently, precise die-casting technology is used to connect the other half to it and die-cast them together to form a fusion structure, ensuring the integrity and stability of the structure.

[0032] Finally, high-strength foam material is injected into the inner cavity of the bag 12 of the floating-blocking belt 10 to enhance its buoyancy and impact resistance.

[0033] In this embodiment, see Figure 7 , 8 The floating tube 20 has a conical structure that is larger at the top and smaller at the bottom, and the floating tube 20 has an elliptical structure when viewed from above, thereby forming the water-breaking structure.

[0034] This barrier is placed in front of the dam and arranged longitudinally at 90 degrees to the dam. Fig. 9 During the summer flood season, the water flow can reach 45,000-65,000 m³ / S and carry a large amount of floating objects, which has a very large impact force. The smooth surface of the structural parts and the elliptical water-breaking structure help reduce water flow separation and turbulence, so that the structure can evenly disperse the pressure when subjected to external force. Improving the strength and durability of the structure can greatly reduce the longitudinal impact force of the water flow on the barrier, increase the impact resistance of the barrier, and extend the service life of the barrier.

[0035] See also Figure 7 The float 20 has a conical structure that is larger at the top and smaller at the bottom. When the float 20 is tilted by a lateral force, the buoyancy point will generate a restoring torque relative to the center of gravity, which helps the float 20 to effectively resist the tilt and restore balance to a vertical state.

[0036] See also Figure 8 The floating tube 20 is an elliptical structure when viewed from above. The elliptical shape helps to effectively drain water, thereby reducing the impact force of the floating tube 20 when it is hit, reducing the adhesion of water to the tube body, reducing the resistance of water flow, thereby reducing the volume and diameter of the underwater anchor fixing cable 30, reducing the installation difficulty and construction period of the floating belt. At the same time, it can also produce a damping effect, which helps to reduce the swing amplitude of the floating tube or floating body and reduce the impact of hydrodynamics on its stability.

[0037] Specifically, in Figure 8 In the top view of the float 20, the distance between the float 20 on the upstream and downstream sides of the river channel is L2, and the distance between the other two sides is L1, and L2 is 2 to 5 times of L1.

[0038] Specifically, the floating cylinder 20 includes an upper cone cylinder 21 and a lower cone cylinder 22 , and the lower cone cylinder 22 is connected to the lower end of the upper cone cylinder 21 .

[0039] Furthermore, ear plates 23 are connected to both sides of the floating tube 20, and ear rings 24 are connected to the bottom of the floating tube 20. The ear rings 24 are connected to the ear plates 23 on both sides through connecting rib plates 25. The floating belt 10 is connected to the ear plates 23, and the mooring rope 30 is connected to the ear rings 24. There are two ear plates 23, one of which is convenient for connecting with the connecting rope 13 of the floating belt 10 through a shackle, and connecting with the mooring rope 30; the other is to further break the water. Figure 8 In the figure, the ear plate 23 is triangular in top view.

[0040] Embodiment 2: On the basis of the first embodiment, see 9, 10, 11, the present invention further comprises a sliding assembly 50, the sliding assembly 50 comprises a chute 52 and a pontoon 53, a plurality of mounting plates 51 are fixedly connected to the bottom of the chute 52, a plurality of supporting wheel groups 54 are arranged on the outer wall of the pontoon 53, the pontoon 53 is installed in the chute 52, and supported by the supporting wheel group 54 and the inner wall of the chute 52, the pontoon 53 is provided with a longitudinal plate 55 at the opening side of the chute 52, and the longitudinal plate 55 is used to connect with the floating belt 10 or the floating tube 20. By setting the sliding assembly 50, when the water level drops, the pontoon 53 moves down with the water level to ensure that the downstream end of the blocking device is connected with the dam body.

[0041] The blocking device is connected to the hole on the longitudinal plate 55 by the shackle during installation. The mounting plate 51 is used for mounting and fixing with the dam body, for example, by using high-strength expansion bolts.

[0042] Embodiment three: See also Fig. 9 , a method for using a large reservoir floating object blocking device, comprising the following steps: S1. Install a sliding assembly 50 on the side of the dam body close to the ship lock; S2. Install the first drift-blocking belt 10 or the first floating cylinder 20 on the longitudinal plate 55 of the sliding assembly 50, and then install the remaining floating cylinders 20 and the drift-blocking belt 10 of the barrier device on the upstream side of the first drift-blocking belt 10 or the first floating cylinder 20. The floating cylinders 20 and the drift-blocking belt 10 are connected in series, and the entire barrier device is arranged along the river channel.

[0043] When each floating cylinder 20 is installed, the mooring rope 30 is connected and fixed to the riverbed 40 through anchor rods. In this way, the downstream end of the entire barrier device is slidably connected to the dam body, the upstream end of the barrier device is located in the river channel, and the bottom of the barrier device is connected to the riverbed 40 through the mooring rope 30. Figure 1 shown.

[0044] The advantages of this application compared with traditional floating barrier: 1. Large carrying capacity: The load-bearing structure adopted by the present invention is compared with the traditional floating barrier belt. The traditional floating barrier belt mostly relies on rubber belt as the load-bearing medium, which has limited load-bearing capacity and is often difficult to cope with the accumulation pressure of a large number of floating objects, causing the floating barrier belt to break. The core highlight of the present invention is that it uses a high-strength horizontal load-bearing connecting rope 13 to undertake the load-bearing task. The connecting rope 13 uses a 20mm diameter steel wire rope with a maximum load-bearing capacity of up to 35t, which is more than 10 times higher than the existing floating barrier belt. This significantly improved load-bearing capacity means that even in extreme situations, such as when a large number of floating objects rush in at the same time or encounter strong water flow impact, the device can still remain stable and is not prone to breakage or deformation.

[0045] 2. High effective distance: There is a common problem in the application of traditional floating arresting belts, that is, due to the softness of the material and the impact of the water flow, the floating arresting belt is prone to bending and deformation on the water surface. This bending and deformation makes it impossible for the floating arresting belt to achieve the ideal straight floating arresting effect, so a longer length is required to cover the entire pilot channel, which not only increases the material cost, but also increases the difficulty of installation and maintenance. Different from this, the present invention adopts a brand-new design, through the combination of built-in lead blocks and connecting ropes 13: the lead blocks increase the weight of the floating arresting belt 10, so that it can better maintain stability in the water; the linear bearing capacity of the connecting rope 13 makes the floating arresting belt 10 on the water surface closer to a straight line. When the floating arresting belt 10 or the floating drum 20 is tilted by the lateral force, the buoyancy point (i.e., the center of buoyancy) will generate a restoring torque relative to the center of gravity, ensuring that the floating drum can maintain a floating state relatively vertical to the water surface under different loading conditions, thereby effectively solving the problem of bending and deformation of the blocking device on the water surface and the tipping of the blocking device on the water surface. Due to the improvement of the above design, the effective floating arresting distance of the present invention is increased by about 40% compared with the traditional floating arresting belt. This means that under the same drift-blocking effect, the required drift-blocking belt length of the present invention is shorter, which greatly reduces the amount of material used and the installation workload.

[0046] 3. Solve the pain point of not being able to hang lead blocks externally: In traditional solutions for intercepting floating objects in reservoirs, the arresting belt usually increases its vertical force in the water by means of external lead blocks to ensure that the arresting belt can float vertically on the water surface, thereby effectively intercepting floating objects below the water surface. However, due to the wide variety of floating objects in the reservoir, especially hard floating objects such as branches and trunks, these floating objects can easily scrape off the external lead blocks under the impact and drive of the water flow. Once the external lead blocks are scraped off, the arresting belt will lose its vertical support force, causing it to fall under the action of the water flow. This tipping not only makes the arresting belt unable to effectively intercept underwater floating objects, but may also cause the failure of the entire arresting system, thereby affecting the normal operation of the reservoir and environmental protection. The present invention adopts a built-in counterweight 112 (lead block) design, and these lead blocks are evenly and firmly embedded in the structure of the arresting belt 10, and will not fall off due to the impact of external floating objects. Due to the built-in lead block, the floating arresting belt 10 can maintain a stable vertical floating state in the water and will not fall horizontally on the water surface due to the impact of floating objects, thereby ensuring the effective floating arresting depth of the floating arresting belt. The design of the built-in lead block enables the floating arresting belt to continuously maintain an underwater intercepting state, and even in the face of a large number of hard floating objects such as branches and trunks, it can effectively intercept and prevent them from entering the deep part of the reservoir. Compared with traditional external lead blocks, the design of the built-in lead block greatly improves the durability of the floating arresting belt and reduces the maintenance and replacement frequency caused by the fall of the lead block.

[0047] 4. High stability: In the design of traditional floating barrier belts, the internal structure is usually made up of multiple block foams. Once the outer rubber bladder of the floating barrier belt is damaged due to external force, the joint strength of the block foam joints is relatively low. Under the dual effects of water flow and pressure, the spliced ​​foam is easily dispersed and crushed, causing the buoyancy of the floating barrier belt to drop sharply, or even completely lose buoyancy and become scrapped. The floating barrier belt of the present invention adopts an integrated die-casting process, which can produce a continuous foam structure without splicing gaps, thereby eliminating the weaknesses of the splicing. At the same time, the selected high-strength foam material has excellent pressure resistance and impact resistance, and can maintain its structural integrity and buoyancy even under extreme water flow and floating object pressure.
