Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering technology, specifically relating to a device for intercepting debris on the water surface in water conservancy projects. Background Technology

[0002] Water conservancy projects include various types of engineering facilities, such as flood control dikes, irrigation systems, hydroelectric power stations, reservoirs, river management projects, urban water supply and drainage systems, and soil and water conservation projects. When using debris-blocking floats, several floats can be strung together with ropes and then placed horizontally on the water surface. The strung floats can intercept debris floating on the river surface, thereby achieving the purpose of cleaning the river surface. However, in existing debris interception devices, the floating parts are strung together to block the river. When equipment boats or other vessels are passing through the river, they cannot pass normally. It is necessary to retract part of the interception device to make way for the vessels, which is quite troublesome. The two actions of intercepting debris and the passage of vessels interfere with each other, resulting in poor flexibility and limited applicability. Utility Model Content

[0003] This utility model provides a surface debris interception device for water conservancy projects. It can prevent the interception of debris on the river surface from interfering with the passage of ships, guide the debris on the river surface, collect it and process it centrally, reduce manpower, and is highly flexible. It can be flexibly installed according to river widths and has a wider range of applications.

[0004] This utility model provides the following technical solution: a surface debris interception device for water conservancy projects, comprising several interception floats, with a lever on the outer side of each interception float and a float at the bottom of each interception float, the interception floats and the floats being rotatably connected, several guide plates on the periphery of each float, a connecting rope connected to the bottom of each float, a counterweight on the connecting rope, a connecting rod connected to one end of the connecting rope, a riverbed connector at one end of the connecting rod, an interception partition on one side of each of the interception floats, the interception partition being installed on one side of the river channel, and a sunken net cage installed at the bottom of the interception partition.

[0005] The interceptor buoy has a connecting groove at the bottom center and a connecting shaft matching the connecting groove at the top center of the buoy. The connecting groove is rotatably connected to the inside of the connecting shaft.

[0006] The float is designed as a cone shape, and one end of the connecting rope is fixedly connected to the top of the float.

[0007] Several of the guide plates are evenly spaced around the perimeter of the float, and one side of each guide plate is fixedly connected to the float.

[0008] The push block and the intercepting float are integrated into one structure, and the push block is configured as a sawtooth structure.

[0009] The diameter of the intercepting buoy is larger than the diameter of the top of the float, and several intercepting buoys are arranged at equal intervals.

[0010] The counterweight is provided with connecting ropes at both ends, and the counterweight is connected to the float and the connecting rod respectively through the two connecting ropes.

[0011] The beneficial effects of this utility model are:

[0012] This new type of device can intercept floating debris in a river channel using several intercepting buoys. When equipment vessels or other vessels pass by, the force of the vessels' forward movement pushes the intercepting buoys to the sides of the vessels, opening a passage for them. After the vessels have passed, the buoys close again, ensuring that the interception of debris and the passage of vessels do not interfere with each other. This device guides the debris on the river surface, collects it, and processes it centrally. It reduces manpower, is highly flexible, and can be flexibly installed according to river channels of different widths, making it applicable to a wider range of situations.

[0013] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0019] Please see Figures 1-4The present invention provides the following technical solution: it includes several interception floats 1, with a lever 11 on the outer side of the interception floats 1, and a float 2 at the bottom of the interception floats 1. The interception floats 1 and the floats 2 are rotatably connected. Several guide plates 21 are provided around the perimeter of the floats 2. A connecting rope 3 is connected to the bottom of the floats 2. A counterweight 31 is provided on the connecting rope 3. A connecting rod 32 is connected to one end of the connecting rope 3. A riverbed connector 33 is provided at one end of the connecting rod 32. An interception partition 4 is provided on one side of the several interception floats 1. The interception partition 4 is installed on one side of the river channel, and a sunken net cage 41 is installed at the bottom of the interception partition 4.

[0020] In this embodiment: This novel device comprises several intercepting floats 1 to guide debris on the river surface. Each intercepting float 1 has a lever 11 on its outer side and a float 2 at its bottom. The intercepting floats 1 and float 2 are rotatably connected. By using the intercepting floats 1 and float 2, the device floats on the river surface. The intercepting floats 1 can be rotated by wind force via the lever 11, while the float 2 can be rotated by the force of water flow via the guide plate 21. This guides debris passing between the two intercepting floats 1. Several guide plates 21 are provided around the perimeter of the float 2, and a connecting rope 3 is connected to the bottom of the float 2. The connecting rope 3 is equipped with… A counterweight 31 is provided, and one end of the connecting rope 3 is connected to a connecting rod 32. A riverbed connector 33 is provided at one end of the connecting rod 32. The connecting rope 3, counterweight 31, connecting rod 32, and riverbed connector 33 form a connecting assembly for installing the float 2. The float 2 is installed in the river channel, and the riverbed connector 33 is fixed to the riverbed. The counterweight 31 is pulled by the connecting rod 32, keeping the connecting rope 3 taut. Depending on the depth of the river channel, different numbers of counterweights 31 are placed on the connecting rope 3, ensuring the connecting rope 3 is vertical within the river channel, thereby limiting the position of the intercepting float 1. An intercepting partition is provided on one side of each of the intercepting floats 1. 4. An interception frame 4 is installed on one side of the river channel, and a sunken net cage 41 is installed at the bottom of the interception frame 4. By setting up the interception frame 4 and the sunken net cage 41, the guided debris on the water surface is intercepted, and floating objects are collected and then processed. Depending on the width and shape of the river channel, different numbers of interception floats 1 are installed on the river surface. The riverbed connector 33 is installed on the riverbed, and then the connecting rod 32, counterweight 31 and connecting rope 3 are installed in sequence, so that the float 2 floats on the river surface. The interception float 1 is rotatably connected to the top of the float 2. Through the force of the river water flow, in conjunction with the guide plate 21, the float 2 is driven to rotate inside the river channel, guiding the floating objects passing between the two floats 2. When subjected to wind force, the intercepting float 1 rotates on top of the float 2 via the lever 11, moving the floating objects between the two floats 2. Simultaneously, with the force of the water flow, the floating objects drift towards the intercepting frame 4 on one side of the river channel. The submerged cage 41 of this novel type can rise upwards, and the submerged cage 41 can be manually retrieved from the river channel, thereby collecting and processing the debris intercepted in the intercepting frame 4. When the working equipment or boat passes by the river surface, its forward momentum is greater than the buoyancy of the intercepting float 1, squeezing the intercepting float 1 and causing it to move along both sides of the boat, opening a passage for the passing equipment or boat, and closing again after it has passed.

[0021] A connecting groove 22 is installed at the bottom center of the interception float 1, and a connecting shaft 12 matching the connecting groove 2 is provided at the top center of the float 2. The connecting groove 22 is rotatably connected to the inside of the connecting shaft 12. By setting the connecting groove 22 and the connecting shaft 12, the interception float 1 can rotate at the top of the float 2 when affected by wind. In this new invention, the connecting groove 22 is set as a one-way bearing with the same rotation direction as the float 2.

[0022] The float 2 is designed as a cone shape, and one end of the connecting rope 3 is fixedly connected to the top of the float 2; the connecting rope 3 pulls the float 2, thereby limiting the position of the connecting rope 3.

[0023] Several guide plates 21 are evenly spaced around the perimeter of the float 2, and one side of the guide plate 21 is fixedly connected to the float 2; the several guide plates 21 are evenly spaced around the perimeter of the float 2 so that the float 2 can remain stable when rotating.

[0024] The lever 11 and the intercepting float 1 are integrated into one structure, and the lever 11 is a sawtooth structure. The lever 11 increases the contact surface between the intercepting float 1 and the wind, making it easier to rotate the intercepting float 1, so that even a small wind force can drive the intercepting float 1 to rotate.

[0025] The diameter of the intercepting buoy 1 is larger than the top diameter of the float 2, and several intercepting buoys 1 are set at equal intervals; the intercepting buoy 1 completely covers the top of the float 2, and a channel is left between two floats 2 for floating objects to pass through.

[0026] The counterweight 31 is equipped with connecting ropes 3 at both ends, and the counterweight 31 is connected to the float 2 and the connecting rod 32 respectively through the two connecting ropes 3. The counterweight 31 keeps the connecting ropes 3 taut. The number of counterweights 31 is set on the connecting ropes 3 according to the depth of the river.

[0027] The working principle and usage process of this utility model are as follows: First, different numbers of intercepting floats 1 are installed on the river surface. The riverbed connector 33 is then installed on the riverbed. Next, the connecting rod 32, counterweight 31, and connecting rope 3 are installed in sequence, causing the float 2 to float on the river surface. The intercepting float 1 is rotatably connected to the top of the float 2. Through the force of the river water flow, and in conjunction with the guide plate 21, the float 2 rotates within the river channel, guiding any floating objects passing between the two floats 2. When subjected to wind force, the intercepting float 1 begins to rotate on top of the float 2 via the lever 11, guiding any objects passing between the two floats 2. The floating objects between the floats 2 move, and with the force of the water flow, the floating objects drift into the interception frame 4 on one side of the river channel. The submerged net cage 41 of this new type can rise up and be manually retrieved from the river channel, so that the debris intercepted in the interception frame 4 can be collected and processed. When the working equipment or boat passes by the river surface, its forward force is greater than the buoyancy of the interception float 1, which squeezes the interception float 1 and makes it move along both sides of the boat, opening a passage for the passing equipment and boat, and closing again after it passes.
