Description

Technical Field

[0001] The invention relates to the field of river management, and in particular to an unpowered interception system and interception solution for floating objects in a river. Background Art

[0002] Floating objects on the surface of rivers have always been an important target of river management. In the prior art, there are various management measures for floating objects on the surface of water, such as salvage ships, interception nets, etc. However, the device systems used in the interception schemes of the prior art are either complex in structure and high in cost, or require additional power to drive, or cannot automatically collect floating objects on the surface of water to one side of the shore for easy treatment. There is no prior art that has all three advantages. Summary of the invention

[0003] In response to the problems in the prior art, the present invention provides a non-powered interception system and interception solution for floating objects in rivers, which has three advantages: simple structure and low cost, can operate autonomously without additional power, and can automatically concentrate floating objects on the water surface to one side of the shore for easy handling. It has extremely high practical value.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a non-powered interception system for floating objects in a river, including ropes, floating plates and transmission wheels, the transmission wheels are arranged on both sides of the river, the ropes are respectively passed around the transmission wheels on both sides of the river, and the floating plates are evenly arranged on the ropes to form floating plates in the front row and floating plates in the back row across the river, and intervals are set between adjacent floating plates.

[0005] The rear side of the floating board in the front row is connected to the rope, and the floating board is tilted to the left or right along the direction of the rope. After the tilt, the projections of adjacent floating boards in a straight line on the vertical plane where the rope is located just intersect or overlap, so that the local flow direction of all water flows after passing through the floating boards in the front row will change.

[0006] A vertical rod fixed on the riverbed is arranged at the center of the transmission wheel, and the transmission wheel is rotatably connected to the vertical rod. The height of the transmission wheel is greater than the height of the floating plate. When the water level rises or falls during flood or drought seasons, the floating plate and the rope move with the water surface, and the rope can slide up and down at the transmission wheel as the water level rises and falls.

[0007] Preferably, the transmission wheel is a groove wheel, and the groove on the transmission wheel cooperates with the rope passing around it.

[0008] Preferably, when the rope and the floating board float on the water surface, the rope is just located on the water surface, so that when duckweed is rampant, the rope has the function of intercepting duckweed and has the effect of controlling the amount of duckweed.

[0009] Preferably, a baffle is provided in the direction in which the end of the front row of floating plates away from the rope is inclined, and a sliding hole is provided at the end of the baffle close to the shore, in which a sliding rod is slidably connected, and the sliding rod is fixed on the shore or riverbed, and the end of the baffle away from the shore is divided into two and respectively located above and below the floating plate. The buoyancy of the baffle can make the baffle float on the water surface, so that it can slide up and down with the rise and fall of the water surface, and a drainage hole is provided on the baffle.

[0010] Preferably, the bottom surface of one end of the float close to the rope is tilted downward, which on the one hand compensates for the weight of the rope to make the upper surface of the float level, and on the other hand pushes the water flow under the float downward, reduces the flow of water rushing to the rear layer of rope, and increases the difference in the component of the impact force of the water flow on the front and rear rows of floats.

[0011] Preferably, a depression is provided at the riverbed below the transmission wheel so that when the water level drops, the rope remains in the water after sliding downward on the transmission wheel.

[0012] Preferably, the transmission wheel on the side where the baffle is located is located behind the transmission wheel on the other side, so that an acute angle is formed between the rope and the river channel, which is convenient for storing and collecting floating objects on the water surface.

[0013] The interception scheme of the unpowered interception system for floating objects in a river comprises the following steps:

[0014] S1. Measure the width of the river, then cut a rope twice the length of the river width, and then connect the cut rope end to end;

[0015] S2. Dig two depressions on the riverbed on both sides of the river that are connected to the river, set transmission wheels in the two depressions respectively, then cross the river by boat, pass the ropes around the two transmission wheels respectively, and set the baffles on the shore;

[0016] S3, floating objects on the water surface follow the water flow and move to the floating board where they are intercepted;

[0017] S4. The water flow impacts the side of the front row of floating boards, giving the floating boards a component force along the direction of the ropes. After that, the water flow velocity is reduced and the flow direction is partially changed. When the water flow impacts the side of the rear row of floating boards, its flow direction is basically parallel to the side of the floating boards. Under the dual effects of reduced water flow velocity and parallel impact direction, the component force generated by the rear row of floating boards impacted by the water flow is smaller than the component force generated by the front row of floating boards impacted by the water flow. The difference in component force pushes the floating boards to move around the transmission wheel with the ropes, and at the same time, it moves the floating objects intercepted by the floating boards to one side of the shore;

[0018] S5. The floating objects on the water surface moving toward the shore in step S4 are intercepted and piled up at the baffle, waiting for centralized processing by staff.

[0019] The beneficial effects of the present invention are:

[0020] (1) The present invention can automatically collect floating objects on the water surface to one side of the shore for easy treatment, and can assist in river management work;

[0021] (2) The present invention can operate autonomously without the need for additional power, and can work autonomously and uninterruptedly without the need for manual maintenance after installation. Moreover, the structure is optimized to an extremely streamlined level. On the premise of achieving the innovation goal, the streamlined structure makes it excellent in stability and extremely low in cost, which is in line with the direction of invention and creation and truly has practical value.

[0022] Figure 1 It is a schematic diagram of the overall structure of the present invention. DETAILED DESCRIPTION

[0023] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0024] Example 1

[0025] like Figure 1 A non-powered interception system for floating objects in a river channel of this embodiment includes a rope 1, a floating plate 2 and a transmission wheel 3. The transmission wheel 3 is arranged on both sides of the river channel. The rope 1 passes around the transmission wheels 3 on both sides of the river channel respectively. The floating plates 2 are evenly arranged on the rope 1 to form a floating plate 2 in the front row and a floating plate 2 in the back row across the river channel, and intervals are set between adjacent floating plates 2.

[0026] The rear side of the floating plate 2 in the front row is connected to the rope 1, and the floating plate 2 is tilted to the left along the direction of the rope 1. After the tilt, the projections of the adjacent floating plates 2 in a straight line on the vertical plane where the rope 1 is located just intersect, so that the local flow direction of all water flows through the floating plates 2 in the front row will change.

[0027] A vertical rod fixed on the riverbed is arranged at the center of the transmission wheel 3, and the transmission wheel 3 is rotatably connected to the vertical rod. The height of the transmission wheel 3 is greater than the height of the floating plate 2. When the water level rises or falls during flood or drought seasons, the floating plate 2 and the rope 1 move with the water surface, and the rope 1 can slide up and down at the transmission wheel 3 with the rise and fall of the water level.

[0028] The transmission wheel 3 is a groove wheel, and the groove on the transmission wheel 3 cooperates with the rope 1 passing around it.

[0029] When the rope 1 and the floating board 2 float on the water surface, the rope 1 is just located on the water surface, so that the rope has the function of intercepting the duckweed when the duckweed is rampant, and has the effect of controlling the amount of the duckweed.

[0030] A baffle 4 is provided in the direction in which the end of the front row of floating plates 2 away from the rope 1 is inclined. A sliding hole is provided at the end of the baffle 4 close to the shore. A sliding rod is slidably connected in the sliding hole. The sliding rod is fixed on the riverbed. The end of the baffle 4 away from the shore is divided into two and is respectively located above and below the floating plate 2. The buoyancy of the baffle 4 can make the baffle 4 float on the water surface, so that it can slide up and down with the rise and fall of the water surface. A drainage hole is provided on the baffle 4.

[0031] The bottom surface of one end of the floating plate 2 close to the rope 1 is tilted downward, which on the one hand compensates for the weight of the rope to make the upper surface of the floating plate flush, and on the other hand pushes the water flow under the floating plate downward, reduces the flow of water rushing to the rear layer of rope, and increases the component difference of the water impact force on the front and rear rows of floating plates.

[0032] The riverbed below the transmission wheel 3 is provided with a depression so that when the water level drops, the rope can still be located in the water after sliding downward on the transmission wheel.

[0033] The transmission wheel 3 on the side where the baffle 4 is located is located behind the transmission wheel 3 on the other side, so that an acute angle is formed between the rope 1 and the river channel, which is convenient for storing and collecting floating objects on the water surface.

[0034] An interception scheme of a non-powered interception system for floating objects in a river channel comprises the following steps:

[0035] S1, measure the width of the river channel, then cut a rope 1 twice the length of the river channel width, and then connect the cut rope 1 end to end;

[0036] S2, dig two depressions connected to the river on the riverbed on both sides of the river, set transmission wheels 3 in the two depressions respectively, then cross the river by boat, pass the rope 1 around the two transmission wheels 3 respectively, and set the baffle 4 on the shore;

[0037] S3, floating objects on the water surface follow the water flow and move to the floating plate 2 where they are intercepted;

[0038] S4. The water flow impacts the side of the front row of floating boards 2, giving the floating boards 2 a component force along the direction of the rope 1. Then the water flow velocity is reduced and the flow direction is partially changed. When the water flow impacts the side of the rear row of floating boards 2, its flow direction is basically parallel to the side of the floating boards 2. Under the dual effects of the reduced water flow velocity and the parallel impact direction, the component force generated by the rear row of floating boards 2 being impacted by the water flow is smaller than the component force generated by the front row of floating boards 2 being impacted by the water flow. The difference in component force pushes the floating boards 2 to move around the transmission wheel 3 with the rope 1, and at the same time, it moves the floating objects intercepted by the floating boards 2 to one side of the shore.

[0039] S5. The floating objects on the water surface moving toward the shore in step S4 are intercepted and piled up at the baffle 4, waiting for centralized processing by staff.

[0040] It should be understood that the above are only preferred embodiments of the present invention, and the patent scope of the present invention cannot be limited thereto. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
