Description

Technical Field

[0001] This utility model belongs to the field of water surface floating object interception technology, and specifically relates to a tensile and shock resistant floating object interception dart. Background Technology

[0002] In rivers and dams, floating debris is a common feature on the water surface, impacting both the river and its water quality. This is especially true after the flood season, when larger pieces of debris are more prevalent. Intercepting and removing floating debris is essential for environmental management. Floating debris barriers rely on the buoyancy of floating objects to keep them afloat, forming a barrier. When floating debris approaches the barrier, it is blocked by the screen and cannot continue moving with the current. Simultaneously, due to the barrier's obstruction, the debris gradually accumulates in front of it, facilitating centralized removal and cleanup.

[0003] Currently, commonly used floating debris interceptors use high-strength and flexible connecting materials such as steel wire ropes, iron chains, and nylon ropes to string together several cylindrical floating bodies. Fixed piles and heavy anchors are built on the shore, and ropes or chains are used to connect them to the debris interceptors, ensuring that the debris interceptors can float stably on the water surface to intercept debris and prevent the debris interceptors from drifting with the water flow or waves.

[0004] During the rainy season, the water flow increases dramatically, and the impact and velocity of the water flow increase. As the float deflector functions, it will also be subjected to stronger vibrations. Under such circumstances, the steel wire ropes, iron chains, or nylon ropes connecting the floats are prone to strong pulling due to frequent vibrations, resulting in breakage, detachment, and other damage. This can cause the float deflector to malfunction and lead to a series of dangerous situations. Utility Model Content

[0005] The present invention aims to provide a tensile and shock resistant drift barrier to solve the problem that drift barriers composed of steel wire ropes, iron chains or nylon ropes connecting floating bodies are very prone to strong pulling and breakage or detachment when subjected to strong oscillations.

[0006] This solution provides a tensile and seismic resistant drift barrier, comprising several floating bodies connected by a connecting body. The connecting body includes a hinge and two mounting seats. The hinge includes a base with bushings on both sides. Each bushing has a first shaft hole, and the central axes of the two first shaft holes are perpendicular to each other. The mounting seats have second shaft holes. The two mounting seats are located on both sides of the base, and the first shaft holes on both sides of the base are coaxial with the first shaft holes of the corresponding mounting seats and are rotatably connected by a pin.

[0007] The working principle of this scheme is as follows: the connecting body forms a hinge structure through the hinge (base and bushing) and the mounting seat. The two mounting seats are fixed to the adjacent floating bodies respectively. The bushings on both sides of the base are rotatably connected to the mounting seats through pins.

[0008] When the water flow impact causes the floating body to sway, the bushing and mounting base of the hinge can rotate around the pin in a direction perpendicular to the water flow and in sync with the water flow undulation, so that the floating body forms a "flexible linkage", which disperses the tensile force generated by the water flow impact and avoids the connecting body from bearing unidirectional concentrated stress.

[0009] The beneficial technical effects of this solution are: 1. Significantly improved tensile and seismic resistance: The hinged structure allows the floating body to swing in multiple directions, reducing rigid tension caused by water flow oscillation and lowering the risk of connection failure.

[0010] 2. Adaptable to complex water flow environments: It can automatically adjust its angle when the water flow direction changes or when waves impact, maintaining the overall stability of the drift barrier and avoiding failure due to excessive local stress.

[0011] Furthermore, the pin includes a pin body, with a pin head connected to one end and a pin tail with a diameter smaller than the pin body connected to the other end. A nut is threaded onto the pin tail. The outer diameters of both the pin head and the nut are larger than the first and second shaft holes. The pin head at one end and the threaded pin tail at the other end are secured by the nut. The outer diameters of the pin head and nut are larger than the shaft hole diameter, forming a "locking" structure to prevent the pin from coming out of the shaft hole. When the connecting body is subjected to tensile force, the pin head and nut respectively abut against the end faces of the bushing and the mounting base, transmitting the tensile force to the entire pin and preventing the pin from loosening or falling off.

[0012] The mechanical locking structure ensures that the pin will not fall off under long-term vibration or tension, further preventing the separation of the floating body from causing the drift barrier function to fail.

[0013] Furthermore, both the bushing and the pin body are provided with threaded holes of the same inner diameter. These threaded holes are coaxial, and the two are secured together with bolts. The coaxial threaded holes on the bushing and pin body, when tightened with bolts, create a rigid connection between the pin and the bushing, restricting relative rotation. When water flow impacts and causes the hinge to sway, the bolts prevent the pin from spinning freely within the bushing, avoiding wear or loosening of the pin due to long-term friction.

[0014] Bolt reinforcement reduces the relative movement between the pin and the bushing, reduces structural failure caused by frictional wear, improves fatigue strength, and extends the service life of the connection.

[0015] Furthermore, the mounting base includes a mounting plate and two connecting plates vertically connected to the mounting plate. The connecting plates have a second shaft hole, and the bushing is located between the two connecting plates. The mounting base consists of a mounting plate and two vertical connecting plates. The second shaft hole on the connecting plate is coaxial with the bushing, and the bushing is located between the two connecting plates, forming a "clamping" structure. When the float is subjected to tension, the vertical connecting plates of the mounting base can distribute the force to the mounting plate, resisting deformation through a rigid structure and preventing the shaft hole from being twisted due to force, thus affecting the pin connection.

[0016] The three-dimensional structural design improves the bending and shear strength of the mounting base, enabling it to withstand greater water flow impact and enhancing its load-bearing capacity.

[0017] Furthermore, reinforcing plates are connected between both sides of the bushing and the base, and between the mounting plate and the connecting plate. These reinforcing plates, added between the bushing and the base, and between the mounting plate and the connecting plate, form a triangular support structure through welding or bolting. The reinforcing plates disperse stress concentrated at the connection points over a larger structural area, reducing localized deformation, improving overall rigidity and deformation resistance, and extending service life.

[0018] Furthermore, the floating body has a box-shaped structure with internal reinforcing ribs. When the floating body is subjected to water flow impact, the box-shaped structure provides sufficient buoyancy. The combination of the box-shaped structure and the reinforcing ribs allows the floating body to resist water flow impact and withstand the tensile force of the connecting parts, preventing the float barrier from failing due to its own damage.

[0019] Furthermore, mounting holes are provided at both ends of the float, and the two ends of the reinforcing rib pass through the mounting holes and are connected to the mounting base. The reinforcing rib is directly connected to the mounting base, transferring the tensile force from the connecting body to the interior of the float, reducing local stress at the connection point and improving the overall tensile strength.

[0020] Furthermore, the reinforcing rib is tubular. The tubular reinforcing rib can reduce weight through its hollow structure while maintaining bending strength.

[0021] Synergistic effects of this solution: The above solution addresses existing problems from three aspects: the mobility of the connected body, structural strength, and stress distribution, through the synergy of "hinged flexible connection, structural rigid reinforcement, and load distribution design".

[0022] The hinged structure disperses the impact force through rotation, avoiding rigid tension; Optimization of the pin, mounting base, and reinforcing plate ensures connection reliability and fatigue resistance; The structural design of the floating body and reinforcing ribs improves the overall load-bearing capacity.

[0023] Ultimately, this will enable the drift barrier to operate stably in high-velocity, high-oscillation environments, reducing the risk of breakage and detachment, and lowering maintenance costs. Attached Figure Description

[0024] Figure 1 This is a structural schematic diagram of a tensile and seismic resistant drift barrier according to the present invention; Figure 2 for Figure 1 The main view; Figure 3 This is a schematic diagram of the hinged component. Detailed Implementation

[0025] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: second shaft hole 1, connecting plate 2, mounting plate 3, floating body 4, pin 5, hinge 6, base 61, bushing 62, first shaft hole 63, bolt 7, and threaded hole 8.

[0026] The basic implementation examples are as follows: Figures 1 to 3 As shown: A tensile and seismic resistant drift barrier includes several floating bodies 4 (two are shown in the figure), which are connected by a connecting body. The connecting body consists of a hinge 6 and two mounting seats. The hinge 6 includes a base 61, with bushings 62 on both sides of the base 61. The bushings 62 have first shaft holes 63, and the central axes of the two first shaft holes 63 are perpendicular to each other. The mounting seats include a mounting plate 3 and two connecting plates 2 vertically connected to the mounting plate 3. The connecting plates 2 have second shaft holes 1. The two mounting seats are located on both sides of the base 61. The first shaft holes 63 on both sides of the base 61 are coaxial with the corresponding second shaft holes 1 of the mounting seats and are rotatably connected by a pin 5. The pin 5 includes a main body, one end of which is connected to a pin head, and the other end is connected to a pin tail with a diameter smaller than the main body of the pin 5. A nut is threaded onto the pin tail, and the outer diameters of both the pin head and the nut are larger than the first shaft holes 63 and the second shaft holes 1. Both bushing 62 and pin 5 have threaded holes 8 with the same inner diameter. After the threaded holes 8 on both are coaxial, they are reinforced by bolts 7.

[0027] As an optimized design, reinforcing plates are connected between the bushing 62 and the base 61 on both sides, and between the mounting plate 3 and the connecting plate 2. The bushing 62 is located between the two connecting plates 2.

[0028] The floating body 4 has a box-shaped structure with tubular reinforcing ribs inside. The two ends of the floating body 4 have mounting holes, and the two ends of the reinforcing ribs pass through the mounting holes and are connected to the mounting base.

[0029] The connecting body forms a hinged structure through the hinge 6 (base 61 and bushing 62) and the mounting base. The two mounting bases are fixed to adjacent floating bodies 4 respectively. The bushings 62 on both sides of the base 61 are rotatably connected to the mounting bases via pins 5. When the water flow impact causes the floating bodies 4 to sway, the bushings 62 of the hinge 6 are rotatably connected to the mounting bases via pins 5. The mounting bases can rotate around the pins 5 in directions perpendicular to the water flow and synchronous with the water flow fluctuations, creating a "flexible linkage" between the floating bodies 4. This disperses the tensile force generated by the water flow impact and prevents the connecting body from bearing unidirectional concentrated stress. Simultaneously, the pin head and nut of the pin 5 form a "locking" structure to prevent disengagement. The reinforcing plates of the bushings 62 and the mounting bases disperse stress, and the cooperation between the floating bodies 4 and the reinforcing ribs enhances the overall load-bearing capacity, ensuring stable operation of the structure under dynamic stress.

[0030] This solution has the following technical advantages: Significantly improved tensile and seismic resistance: The hinged structure allows the floating body 4 to swing in multiple directions, reducing rigid tension caused by water flow oscillation and lowering the risk of connection failure; structural optimizations such as pin 5 and reinforcing plate enhance fatigue resistance and further improve overall stability.

[0031] Adaptable to complex water flow environments: It can automatically adjust its angle when the water flow direction changes or when waves impact it. Through the synergy of "flexible linkage" and "rigid reinforcement", it maintains the overall stability of the drift barrier and avoids failure due to excessive local stress.

[0032] Structural reliability and economic optimization: The anti-detachment design of pin 5, the three-dimensional structure of the mounting base, and the supporting role of the reinforcing plate ensure long-term reliable operation of the connection parts and reduce the risk of detachment; the design of the float 4 and the tubular reinforcing ribs reduces weight while maintaining strength, thereby reducing the overall load and maintenance costs. Through the synergy of "hinged flexible connection, rigid structural reinforcement, and load-distributing design," the drift barrier achieves long-term stable operation in high-velocity and strong oscillation environments, comprehensively improving service life and economy.
