Description

Technical Field

[0001] The utility model relates to the technical field of surface floating object interception, in particular to a floating box drift interception device with stronger anti-tilting ability and capable of bearing two-way forces. Background Art

[0002] At present, most floating boxes of surface drift interception devices are unidirectionally stressed. The floating boxes of the drift interception devices are only affected by the water flow impact force in the downstream direction and not by the water flow impact force in the upstream direction. However, in actual applications, the water surface conditions are complex and changeable, and vortices may occur on the water surface, causing the water flow direction to change from downstream to upstream. Existing drift interception devices are not specifically designed for intercepting drift in the case of two-way water flow.

[0003] In the prior art, a Chinese invention patent document with the publication number CN116443190A and the publication date of July 18, 2023 was proposed to solve the above-mentioned existing technical problems. The technical solution disclosed in the patent document is as follows: A floating box drift interception device capable of bearing two-way forces, which includes end hinge seats at both ends. Each end hinge seat is connected to a connecting support. A steel wire rope is connected between the two connecting supports. A floating box device is installed on the steel wire rope through a sliding seat. There are multiple floating box devices, and the multiple floating box devices are arranged side by side on the steel wire rope. A chain net is installed between adjacent floating box devices.

[0004] During the actual use of the above technical solution, the following problems will occur: The suspension points of the suspension chain of the above drift interception device are set on the top surface of the floating box, and the distance between the force application point and the suspension point is very large, that is, the lever arm of the tilting moment of the floating box is very large, resulting in a very large tilting moment on the floating box, causing the floating box to have a large tilting angle under the action of the water flow. Only by increasing the floating box and counterweight can the tilting angle be reduced, which will lead to a large increase in cost. Summary of the Invention

[0005] To solve the above technical problems, the utility model provides a floating box drift interception device with stronger anti-tilting ability and capable of bearing two-way forces, which can effectively solve the problem of weak anti-tilting ability in the prior art, and has a simple structure, reliable performance and safety.

[0006] The utility model is realized by adopting the following technical solutions:

[0007] A floating box drift interception device with stronger anti-tilting ability and capable of bearing two-way forces includes end hinge seats, connecting supports connected to the end hinge seats, several floating boxes, and mounting seats arranged below the top surface of the floating boxes; a suspension chain is connected between the two connecting supports; a through hole for the suspension chain to pass through is formed in the floating box; the floating boxes are respectively connected to the suspension chain through the mounting seats, and the floating boxes can rotate around the suspension chain.

[0008] The through hole penetrates upward through the top surface of the floating box to form a groove.

[0009] The mounting base is arranged in the groove.

[0010] The mounting base is a bearing seat; the suspension chain includes a connecting member and a connecting shaft, and the connecting shaft is matched with the bearing in the bearing seat; the connecting member is configured to connect the connecting support and the connecting shaft or is configured to connect two adjacent connecting shafts.

[0011] Two mounting bases are provided on each floating box, and the two mounting bases are respectively located at both ends of the connecting shaft.

[0012] The connecting member is a connecting anchor chain or a steel wire rope.

[0013] Connecting heads for connecting with the connecting member are further provided at both ends of the connecting shaft.

[0014] The floating box includes an intercepting portion located at the upper part and a counterweight portion located below the intercepting portion, and the intercepting portion and the counterweight portion are connected by a connecting flange or are welded together.

[0015] A chain net is further arranged between two adjacent floating boxes.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. In the present utility model, the mounting base is arranged below the top surface of the floating box, and a through hole for the suspension chain to pass through is further formed in the floating box, so that the suspension point of the suspension chain can be arranged close to or below the water surface. Such a design can reduce the lever arm of the tilting moment received by the floating box, thereby reducing the tilting moment received by the floating box and making the anti-tilting ability of this floating debris interception device very strong. For other floating debris interception devices, such as the patent documents mentioned in the background art, the suspension point of the suspension chain is arranged on the top surface of the floating box, which increases the tilting lever arm received by the floating box, thereby increasing the tilting moment received by the floating box and resulting in a large tilting angle.

[0018] When the water flow velocity changes, sudden situations or other uncontrollable factors are encountered, the floating box of the floating debris interception device can freely rotate along the suspension chain. The floating box of this floating debris interception device can be stressed in two directions, can adapt to the working conditions where the water flow direction changes, and can ensure the stable and safe operation of the floating debris interception device and the effect of intercepting floating objects. Moreover, the structure of this floating debris interception device is simple and reliable.

[0019] 2. In the present utility model, the through hole penetrates upward through the top surface of the floating box to form a groove, and the processing method is simpler and is also convenient for better installation and disassembly.

[0020] 3. The mounting base is arranged in the groove, which is more convenient for installation and can also weaken the influence of the external environment on the mounting base during use.

[0021] 4. The suspension chain of this floating debris interception device is composed of a way that multiple sections of connecting parts and multiple sections of connecting shafts are alternately connected. The connecting parts make the suspension chain a flexible system that can be bent and twisted. The floating box is connected to the connecting shaft through a mounting seat, enabling the floating box to rotate freely around the connecting shaft, and the rotation process is more stable, meeting the requirement that the floating box swings freely with the waves, so that no constraint load occurs, ensuring the service life of the floating debris interception device.

[0022] In addition, through the settings of the end hinge seat, connecting support, and connecting parts, an end connection that can rotate both in the horizontal plane and in the vertical plane is provided for the suspension chain of this floating debris interception device, which can well meet the working condition requirements that the horizontal angle and vertical angle at the end of the suspension chain change with the water level and flow velocity.

[0023] 5. The number of mounting seats is two, which are respectively located at both ends of the connecting shaft, making the connection of the floating box more stable and the rotation process of the floating box more stable.

[0024] 6. The connecting part is a connecting anchor chain or wire rope, which has high strength, good rigidity, good fatigue resistance, and the bracing will not loosen, with a long service life.

[0025] 7. Connecting heads for connecting with the connecting part are also provided at both ends of the connecting shaft, making the connection between the connecting shaft and the connecting part more stable and more convenient.

[0026] 8. The interception part and the counterweight part are connected by a connecting flange or welding. The interception part and the counterweight part are set separately, which is convenient for the manufacture and transportation of the floating box and also convenient for replacing damaged components.

[0036] Embodiment 1

[0037] As a preferred embodiment of the present invention, the present invention includes a two-way force-bearing floating box drift interception device with stronger anti-tilting ability, including an end hinge seat 1, a connecting support 2 connected to the end hinge seat 1, several floating boxes 4, and a mounting seat 5 arranged below the top surface of the floating box 4. A suspension chain is connected between the two connecting supports 2. Among them, the suspension chain can be a steel wire rope.

[0038] The structures of the end hinge seat 1, the connecting support 2, the floating box 4, and the mounting seat 5 can adopt conventional technical means in the art, and this embodiment does not improve them. For example, the mounting seat 5 can include an upper mounting seat and a lower mounting seat. The upper mounting seat and the lower mounting seat are in a semi-circular ring structure, and the upper mounting seat and the lower mounting seat are fixed to each other by bolts. A steel wire rope fixing frame with a cylindrical structure that matches the channel is arranged in the channel formed by the two enclosing each other. The mounting seat 5 can be sleeved outside the steel wire rope fixing frame, and the steel wire rope passes through the through hole in the steel wire rope fixing frame.

[0039] More specifically, two mounting seats 5 can be correspondingly arranged on each floating box 4, and the two mounting seats 5 can be respectively located on two sides of the floating box 4. A through hole is arranged in the area of the floating box 4 corresponding to the position of the mounting seat 5, that is, a through hole is arranged below the top surface of the floating box 4 for the steel wire rope to pass through. The floating box 4 is respectively connected to the steel wire rope through the mounting seat 5, and the floating box 4 can rotate around the steel wire rope. When the water flow velocity changes, sudden situations or other uncontrollable factors occur, the floating box 4 of the drift interception device can rotate freely along the steel wire rope to ensure the stable and safe operation of the drift interception device and the effect of intercepting floating objects.

[0040] Embodiment 2

[0041] As a preferred embodiment of the present invention, the present invention includes a two-way force-bearing floating box drift interception device with stronger anti-tilting ability, including an end hinge seat 1, a connecting support 2 connected to the end hinge seat 1, and several floating boxes 4. A suspension chain is connected between the two connecting supports 2. The suspension chain can be a steel wire rope.

[0042] A through hole for the suspension chain to pass through is also formed in the floating box 4. For the convenience of installation and processing, the through hole can penetrate upward through the top surface of the floating box 4 to form a groove 10. The groove 10 penetrates the length direction of the floating box 4. An installation seat 5 is also arranged in the groove 10, so that the installation seat 5 is located below the top surface of the floating box 4. The structure of the installation seat 5 can be the same as that in Embodiment 1. The floating box 4 is respectively connected to the suspension chain through the corresponding installation seat 5, and the floating box 4 can rotate around the suspension chain. Through this structure, the suspension point of the suspension chain of the floating debris interception device is located below the top surface of the floating box 4. Specifically, it can be set near or below the water surface. Such a design can reduce the tilting force arm of the floating box 4, thereby reducing the tilting moment of the floating box 4, so that the floating debris interception device can adapt to the working conditions where the water flow direction changes.

[0043] As Figure 4 and Figure 5 shown are respectively the moment schematic diagrams of the suspension points of the floating box 4 in the present invention and the prior art; it can be seen from the figure that when the suspension point is located at the top of the floating box 4, its tilting force arm L is significantly greater than the force arm L1 when the suspension point is near the water surface. Therefore, its tilting moment is also greater than the tilting moment when the suspension point is near the water surface.

[0044] Embodiment 3

[0045] As another preferred embodiment of the present invention, the present invention includes a floating debris interception device with a floating box that can be stressed bidirectionally and has stronger anti-rotation ability, including an end hinge seat 1, a connection support 2 connected to the end hinge seat 1, a plurality of floating boxes 4, and a plurality of installation seats 5. A suspension chain is connected between the two connection supports 2. The suspension chain includes a connecting piece and a connecting shaft 14. The connecting piece can be a steel wire rope. A through hole for the connecting shaft 14 to pass through is also formed in the floating box 4. Two installation seats 5 are provided on each floating box 4. The installation seat 5 is a bearing seat, and the bearing in the bearing seat matches the connecting shaft 14. The two installation seats 5 are respectively fixed on the two sides of the floating box 4 and are located below the top surface of the floating box 4, corresponding to the position of the through hole. The connection support 2 is connected to the connecting shaft 14 through a steel wire rope, and the adjacent two connecting shafts 14 are also connected through a steel wire rope. Specifically, both ends of the connecting shaft 14 extend out of the floating box 4, pass through the bearings and are connected to the steel wire rope.

[0046] Embodiment 4

[0047] As the best embodiment of the present invention, referring to the attached Figure 1 and the attached Figure 2, the utility model includes a two-way force-bearing floating box drift interception device with stronger anti-tilting ability, which includes an end hinge seat 1, a connection support 2, a floating box 4, a mounting seat 5 and a suspension chain. The suspension chain includes a connecting piece and a connecting shaft 14. The connecting piece is a connecting anchor chain 3. The number of the floating boxes 4 can be several, and a chain net 7 is also arranged between two adjacent floating boxes 4.

[0048] Specifically, referring to the attached drawings of the specification Figure 3 , the floating box 4 includes an interception part 11 located at the upper part and a counterweight part 12 located under the interception part 11. The interception part 11 and the counterweight part 12 are connected by a connecting flange 13. Alternatively, the interception part 11 and the counterweight part 12 can be connected by welding.

[0049] The interception part 11 is filled with a high molecular anti-sinking material 8. The high molecular anti-sinking material 8 can adopt conventional technical means in the field, such as a material with the model of SCOHELXB-3040. A counterweight block 9 is arranged in the counterweight part 12.

[0050] Furthermore, a groove 10 is arranged on the interception part 11. The groove 10 penetrates upward through the top surface of the interception part 11 and penetrates the length direction of the interception part 11. Two mounting seats 5 are arranged in each groove 10. Referring to the attached drawings of the specification Figure 6 , the mounting seat 5 is a bearing seat, and the connecting shaft 14 matches the bearing in the bearing seat. The bearings in the two bearing seats are respectively sleeved at both ends of the same connecting shaft 14, so that the floating box 4 can rotate freely around the connecting shaft 14, meeting the requirement that the floating box 4 swings freely with the waves, so that no constraint load occurs, and the service life of the drift interception device is guaranteed. Connecting heads 6 for connecting with the connecting anchor chain 3 are also arranged at both ends of the connecting shaft 14.

[0051] Furthermore, as Figure 2 shown, in this embodiment, a hanging grid 15 is arranged at the front end of each floating box 4 facing the oncoming flow direction. The hanging grid 15 is fixedly connected with the floating box 4, and the cross section of the hanging grid 15 is perpendicular to the water flow direction.

[0052] The end hinge seat 1 is fixed on the left and right anchoring piers. One end of the connection support 2 is connected with the end hinge seat 1, and the other end is connected with the connecting shaft 14 on the adjacent floating box 4 through the connecting anchor chain 3. The connecting shafts 14 between two adjacent floating boxes 4 are also connected through the connecting anchor chain 3. Finally, the suspension chain of this drift interception device is formed by the alternating connection of multiple sections of connecting anchor chains 3 and multiple sections of connecting shafts 14, and this suspension chain is a flexible system that can be bent and twisted.

[0053] Compared with the conventional floating debris blocking device, the suspension point of the suspension chain in this embodiment is no longer located on the top surface of the floating box 4, but is set at the groove 10. The position of the suspension point is lowered and can be close to or under the water surface, which can reduce the tilting force arm of the floating box 4, thereby reducing the tilting moment of the floating box 4 and enabling the floating debris blocking device in this embodiment to adapt to the working conditions where the water flow direction changes. The end hinge seat 1, the connecting support 2 and the connecting anchor chain 3 provide an end connection for the suspension chain that can rotate both in the horizontal plane and in the vertical plane, which can well meet the working condition requirements that the horizontal angle and the vertical angle of the end of the suspension chain change with the water level and the flow velocity.

[0054] In summary, after reading the documents of the present utility model, various other corresponding transformation schemes made by those of ordinary skill in the art without creative mental labor according to the technical solutions and technical concepts of the present utility model all fall within the scope protected by the present utility model.
