Abstract
Description
Technical Field
[0001] The utility model relates to a floating debris interception device, in particular to a floating debris interception device with a suspension chain located underwater. Background Art
[0002] In the reservoir areas of some large-scale hydropower stations, during the flood season, sundries such as plant residues and domestic garbage will enter the reservoir along with the water flow, affecting the ecological environment of the reservoir area. Currently, floating debris interception devices are usually used to intercept these sundries and then clean them up uniformly. The floating debris interception devices in the prior art generally consist of multiple floating barrels connected in series. By relying on the buoyancy of the floating barrels, a dike is constructed to intercept the floating objects in the oncoming flow direction. For example, Patent CN217267343U discloses a floating debris interception device with a rotatable floating box; the device includes a floating debris interception mechanism fixed at both ends to an assembly foundation. The floating debris interception mechanism includes multiple floating barrel devices for intercepting floating debris and a main cable for connecting the floating barrel devices. The floating barrel devices are sequentially connected in series to the main cable, and both ends of the main cable are fixedly assembled to the assembly foundations on both sides through anchoring devices. The floating barrel devices are on the rotatable main cable, and the floating barrel devices can be rotated to flip when overloaded.
[0003] However, whether it is the floating debris interception device widely used in the market currently or the one mentioned in the above patent, the ropes connecting the floating barrels are usually located on the top surfaces of the floating barrels. This increases the tilting force arm of the floating box, thereby increasing the tilting moment of the floating box and making it unable to adapt to the working conditions of high flow velocity and deep underwater pollution interception. Summary of the Utility Model
[0004] The utility model aims to solve the problem of insufficient interception depth of the floating debris interception device due to the hanging cable connection position in the prior art, and proposes a floating debris interception device with a suspension chain located underwater. This device has the advantages of being able to adapt to high flow velocity, deep underwater pollution interception, simple structure, reliable performance, and safety.
[0005] In order to achieve the above utility model purpose, the technical solution of the utility model is as follows:
[0006] A floating debris interception device with a suspension chain located underwater, including a floating debris interception mechanism fixed at both ends to an assembly foundation. The floating debris interception mechanism includes multiple floating box devices for intercepting floating debris and a suspension chain for connecting the floating box devices. The floating box devices are sequentially connected in series to the suspension chain, and both ends of the suspension chain are assembled to the assembly foundations on both sides through anchoring mechanisms; it is characterized in that the front end surface of each floating box device facing the oncoming flow direction is connected to the suspension chain, and the floating box device can be rotated to flip around the suspension chain when overloaded.
[0007] In a certain embodiment, the suspension chain includes multiple floating box connection devices connected in series in sequence, and each floating box connection device correspondingly connects a floating box device.
[0008] In one embodiment, two adjacent buoyancy chamber connection devices are connected by an intermediate connecting anchor chain.
[0009] In one embodiment, the buoyancy tank connection device includes a connection shaft and bearing seats arranged at both ends of the connection shaft, the bearing seats are connected to the buoyancy tank device, and the bearings in the two bearing seats are mounted on the same connection shaft.
[0010] In one embodiment, a floating net is provided at the front end of each buoyancy device facing the incoming flow direction, and the floating net is connected to the buoyancy device or the hanging chain.
[0011] In one embodiment, a chain net is installed in the gap between two adjacent floating intercepting nets.
[0012] In one embodiment, the buoyancy box device includes a front box and a rear box that are integrally connected. The front box is located on the side close to the incoming flow and is filled with a polymer anti-sinking material, while the rear box is filled with counterweights.
[0013] In one embodiment, the anchoring mechanism is connected to the suspension chain and enables the suspension chain to obtain the freedom of vertical rotation and rotation around a horizontal plane.
[0014] In one embodiment, the anchoring mechanism includes an end hinge seat and a connecting support, wherein the end hinge seat is fixedly arranged on an assembly base, one end of the connecting support is vertically rotatably connected to the end hinge seat, and the other end is rotatably connected to the end anchor chain of the suspension chain system.
[0015] The working principle of the utility model is as follows:
[0016] The floating device is installed on both sides of the river to be cleaned, so that the floating net is facing the incoming flow direction. The floating box device and the floating net intercept the floating objects on the river. Since the hanging point of the floating box device is located underwater, the overturning moment of the floating box can be reduced, so that the device can adapt to the working conditions of high flow rate and underwater pollution interception depth;
[0017] When the floating arresting device encounters a change in water flow velocity, an emergency or other uncontrollable factors, the pontoon device and the pontoon connecting shaft can rotate freely along the suspension chain system to automatically balance the force to ensure the safe operation of the floating arresting device.
[0018] In summary, the utility model has the following advantages:
[0019] 1. The utility model's floating interception device has the advantages of being able to adapt to high flow rates, deep underwater interception, simple structure, reliable performance, and safety.
[0020] 2. In the present utility model, by setting the suspension point of the floating box device on the front end face facing the oncoming flow direction, the suspension chain is located below the water surface when the debris interception device is working properly.

[0021] 3. In the present utility model, the floating box device includes a front box and a rear box that are integrally connected. The front box is located on the side close to the oncoming flow, and its interior is filled with a polymer anti-sinking material to prevent the floating box device from sinking to the bottom; the interior of the rear box is filled with counterweight blocks to maintain the balance of the floating box device under the debris interception force state;

[0036] To more clearly illustrate the present invention, the present invention will be further described below in conjunction with preferred embodiments and the accompanying drawings. Those skilled in the art should understand that the specific content described below is illustrative rather than restrictive, and should not be used to limit the protection scope of the present invention.
[0037] Embodiment 1
[0038] As a basic implementation mode, this embodiment provides a drift net device with a suspension chain located underwater, including a drift net mechanism fixed at both ends on an assembly foundation. The drift net mechanism includes a plurality of floating box devices 4 for drifting and a suspension chain for connecting the floating box devices 4. The floating box devices 4 are sequentially connected in series on the suspension chain, and both ends of the suspension chain are assembled on the assembly foundations on both sides through an anchoring mechanism; the front end surface of each floating box device 4 facing the oncoming flow direction is connected to the suspension chain, and the floating box device 4 is rotated through a rotatable assembly to turn over when overloaded.
[0039] In the drift net device of this embodiment, by setting the suspension point of the floating box device 4 on the front end surface facing the oncoming flow direction, the suspension chain is located below the water surface when the drift net device is working properly. Such a design can reduce the tilting force arm of the floating box, thereby reducing the tilting moment of the floating box, so that the device can adapt to working conditions with high flow velocity and deep underwater pollution interception.
[0040] As Figure 4 and Figure 5 show the moment schematic diagrams of the suspension points of the floating box device 4 in the present invention and the prior art respectively; it can be seen from the figure that when the suspension point is located at the top of the floating box device 4, its tilting force arm L is significantly greater than the force arm L1 when the suspension point is underwater, so its tilting moment is also greater than the tilting moment when the suspension point is underwater.
[0041] Embodiment 2
[0042] As a preferred embodiment, this embodiment provides a floating debris interception device with a suspension chain underwater, as Figure 1 , which includes a floating debris interception mechanism fixed at both ends on an assembly foundation.

The floating box devices 4 are successively connected in series on the suspension chain, and both ends of the suspension chain are assembled on the assembly foundations on both sides through an anchoring mechanism; the front end surface of each floating box device 4 facing the oncoming flow direction is connected to the suspension chain, and the floating box device 4 is rotatably assembled to flip when overloaded.
[0043] In this embodiment, as Figure 1 and Figure 3 shown, the floating box device 4 includes a front box and a rear box integrally connected. The front box is located on the side close to the oncoming flow, and its interior is filled with a polymer anti-sinking material 8 to prevent the floating box device 4 from sinking to the bottom; the interior of the rear box is filled with counterweight blocks 9 to maintain the balance of the floating box device 4 in the state of being stressed by intercepting debris.
[0044] Preferably, in this embodiment, the suspension chain includes a plurality of floating box connection devices 5 connected in series. Each floating box connection device 5 corresponds to and connects a floating box device 4, and an intermediate connecting anchor chain 6 is used to connect between two adjacent floating box connection devices 5.
[0045] As Figure 6 and Figure 7 shown, the floating box connection device 5 includes a connecting shaft 11 and bearing seats 10 arranged at both ends of the connecting shaft 11.

[0046] In this embodiment, the suspension chain system is composed of an alternating connection method of multiple sections of anchor chains and multiple sections of connecting shafts 11. The anchor chain makes the suspension chain system a flexible system that can be bent and twisted, and the floating box connection device 5 is used for the floating box to be connected to the suspension chain system through the two bearing seats 10, so that the floating box can freely rotate around the connecting shaft 11 (suspension chain system), meeting the requirement that the floating box swings freely with the waves, thereby preventing the occurrence of constraint loads and ensuring the service life of the floating debris interceptor.
[0047] When the floating debris interception device encounters changes in water flow velocity, sudden situations or other uncontrollable factors, the floating box device 4 and the floating box connecting shaft 11 can freely rotate along the suspension chain system, automatically balancing the stress to ensure the safe operation of the floating debris interception device.
[0048] Furthermore, as Figure 2 shown, in this embodiment, a floating debris interception net 12 is provided at the front end of each floating box device 4 facing the oncoming flow direction. The floating debris interception net 12 is fixedly connected to the floating box device 4 or the suspension chain, and the cross-section of the floating debris interception net 12 is perpendicular to the water flow direction.
[0049] Furthermore, asFigure 2 As shown in the figure, a chain net 7 is also installed at the gap between two adjacent floating debris barriers 12 (the position where the intermediate connecting anchor chain 6 is located) to prevent floating debris from flowing out through the gap between the floating box devices 4.

[0051] As a preferred embodiment, this embodiment provides a floating debris barrier with the suspension chain underwater, including a floating debris barrier mechanism fixed at both ends on the assembly foundation. The floating debris barrier mechanism includes a plurality of floating box devices 4 for floating debris interception and a suspension chain for connecting the floating box devices 4. The floating box devices 4 are sequentially connected in series on the suspension chain, and both ends of the suspension chain are assembled on the assembly foundations on both sides through an anchoring mechanism; the front end face of each floating box device 4 facing the oncoming flow direction is connected to the suspension chain, and the floating box device 4 is rotatably assembled so that the floating box device 4 can be turned over when overloaded.

The front box is located on the side close to the oncoming flow, and its interior is filled with a polymer anti-sinking material 8 to prevent the floating box device 4 from sinking to the bottom; the interior of the rear box is filled with counterweight blocks 9 to maintain the balance of the floating box device 4 under the state of receiving pollution interception force.
[0053] The suspension chain includes a plurality of floating box connecting shafts 11 connected in series. Each floating box connecting shaft 11 corresponds to and connects a floating box device 4, and the adjacent two floating box connecting shafts 11 are connected by an intermediate connecting anchor chain 6.
[0054] As shown in Figure 6 and Figure 7 the figure, the floating box connecting device 5 includes a connecting shaft 11 and bearing seats 10 arranged at both ends of the connecting shaft 11. The bearing seats 10 are connected to the floating box device 4, and the bearings in the two bearing seats 10 are sleeved on the same connecting shaft 11.
[0055] As shown in Figure 2 the figure, a floating debris barrier net 12 is provided at the front end of each floating box device 4 facing the oncoming flow direction, and a chain net 7 is also installed at the gap between two adjacent floating debris barrier nets 12 to prevent floating debris from flowing out through the gap between the floating box devices 4.
[0056] Furthermore, in this embodiment, as shown in Figure 1 and Figure 8 the figure, the anchoring mechanism includes an end hinge seat 1 and a connecting support 2. The end hinge seat 1 is fixedly arranged on the assembly foundation. One end of the connecting support 2 is vertically rotatably connected to the end hinge seat 1 through a pin shaft, and the other end is horizontally rotatably connected to an end connecting anchor chain 3 connected to the end of the suspension chain system.
[0057] In this embodiment, the end hinge support 1, the connecting support 2, and the end connecting anchor chain 3 provide an end connection for the suspension chain system that can rotate in both the horizontal plane and the vertical plane, which can well meet the working condition requirements that the horizontal angle and the vertical angle at the end of the suspension chain system change with the water level and the flow velocity.
[0058] The working principle of the present utility model is as follows:
[0059] Install this floating debris interception device on both sides of the river to be cleaned, so that the floating debris interception net 12 faces the oncoming flow direction. The floating box device 4 and the floating debris interception net 12 intercept the floating debris on the river. Since the suspension points of the floating box device 4 are underwater, the overturning moment on the floating box can be reduced, enabling this device to adapt to the working conditions of high flow velocity and deep underwater debris interception.
[0060] When the floating debris interception device encounters changes in water flow velocity, sudden situations, or other uncontrollable factors, the floating box device 4 and the floating box connecting shaft 11 can rotate freely along the suspension chain system to automatically balance the force, ensuring the safe operation of the floating debris interception device.
